Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

With the improvement of living standard of people, new household appliances such as health preserving pots and the like are more and more appeared in the life of people. The health preserving pot can be used for cooking food materials such as tremella, angelica, ganoderma lucidum and the like, so that delicious and nutrient-rich health preserving porridge, fruit tea, health preserving soup and the like can be obtained.

However, when the health preserving pot cooks the health preserving food material, the liquid in the pot may boil to cause an overflow phenomenon. After the health preserving food materials and liquid overflow, the table top can be polluted, the food materials are wasted, and the phenomena of scalding of personnel and the like can be caused. Meanwhile, the food materials in the health preserving kettle are different in types, or the solid food materials and the liquid materials are different in proportion, so that the overflow probability is different when different food materials are cooked in the health preserving kettle. In order to avoid the overflow phenomenon of the health preserving pot during cooking, the invention provides the health preserving pot which can finish normal cooking and avoid food materials from overflowing.

Fig. 1 is a schematic flow chart of a heating control method according to an embodiment of the present invention. As shown in fig. 1, the heating control method provided in this embodiment is applied to a health preserving pot, and specifically includes the following steps:

s101, when the health preserving kettle is in a heating state, whether the health preserving kettle sends an anti-overflow signal is detected.

S102, if the health preserving kettle sends an anti-overflow signal, controlling the heating state of the health preserving kettle according to the anti-overflow signal and the cooking mode of the health preserving kettle, so that the health preserving kettle realizes anti-overflow heating, and different cooking modes correspondingly cook different food materials.

Specifically, the health preserving kettle including the kettle body with can be to the heating device of the internal portion heating of kettle, in addition, in order to realize the anti-overflow function of health preserving kettle, can also be provided with the anti-overflow subassembly in the health preserving kettle, the anti-overflow subassembly is including induction capacitance or induction resistance etc. usually. The induction capacitor or the induction resistor is usually positioned in the upper area of the health preserving kettle body. When the liquid that boils in the health preserving kettle is excessive, the liquid level of liquid rises to contact induction capacitance or inductive resistor, induction capacitance or inductive resistor's the capacitance value or the corresponding emergence of resistance value change this moment, thereby produce and be used for instructing the anti-overflow signal that the interior liquid of health preserving kettle is about to overflow.

Like this, when the health preserving kettle was in the heating state, can detect whether the health preserving kettle sent the anti-overflow signal to the heating process of health preserving kettle is controlled to the number of times that has or the anti-overflow signal sent according to the anti-overflow signal. Wherein, the anti-overflow signal can be sent by the anti-overflow subassembly, also can send by other subassemblies of health preserving kettle. Specifically, when the anti-overflow assembly detects that the primary liquid level rises, a primary anti-overflow signal is sent; and when the liquid level of the liquid drops to a height below the induction capacitor or the induction resistor, the anti-overflow signal disappears.

And when the health preserving kettle sent the anti-overflow signal, can control the heating state of health preserving kettle according to this anti-overflow signal and the cooking mode that the health preserving kettle is located at present, reduce the internal heat that receives of edible material of the kettle of health preserving kettle to let the liquid level of the internal liquid of kettle drop to the height that can not overflow from the internal of kettle. Specifically, the health preserving kettle can have a plurality of different cooking modes, and the different cooking modes correspond to different food material types for cooking. For example, the cooking mode can be cooking fruit tea, various porridge, medicated food, health preserving soup and the like. Corresponding to different edible material types, the proportion of its edible material and liquid to and required temperature and time are all inequality when cooking, therefore it boils the degree of difficulty that overflows and also can have the difference, need adjust the heating state according to the kind of this edible material like this, just can avoid edible material to produce when cooking and spill over, also prevent simultaneously because of heating state adjustment excessively and influenced the effect of cooking of edible material.

Specifically, because the health preserving kettle relies on heating of the heating device to heat the food material when cooking the food material, the heating condition of the food material can be controlled by the heating power of the heating device and the heating time of the food material. At this time, as an optional implementation manner, the step S102 may specifically be: reducing at least one of a heating time and a heating power of the health preserving pot according to the overflow preventing signal and a cooking mode of the health preserving pot.

Specifically, in order to avoid overflowing of the food material during boiling, the heating time and the heating power of the health preserving kettle can be reduced independently, or the heating time and the heating power of the health preserving kettle can be reduced simultaneously. Because no matter reduce heating time or reduce heating power, the homoenergetic that the homoenergetic received by eating material reduces, therefore can effectively avoid the kettle body in cause the boiling phenomenon of eating material because of the heat is too high, prevent that the internal liquid of kettle from spilling over.

It can be understood that the heating time of the health preserving kettle is reduced, and the original continuous heating of the health preserving kettle is usually changed into intermittent heating, so that the heating device is in a non-heating state in the interval between two adjacent times of heating. Therefore, by the intermittent heating mode, the total heat generated by the heating device in the rated time can be reduced, so that the liquid in the kettle body is prevented from being heated, and the overflow is avoided.

Specifically, according to the difference of the material kind of cooking that boils in the health preserving kettle, the health preserving kettle can change into different heating state to carry out the anti-overflow heating according to the characteristic of eating the material. The following is described in detail with reference to specific food material categories:

as an alternative embodiment, the cooking mode of the health preserving pot is used for cooking health preserving soup, and specifically, the health preserving soup can comprise cubilose, red bean soup, white fungus soup, other kinds of health preserving soup and the like. Because the possibility of overflowing during cooking the health preserving soup is high, the heating power or the heating time of the health preserving pot needs to be greatly reduced so as to avoid the overflow phenomenon. Fig. 2 is a schematic flow chart of another heating control method according to an embodiment of the present invention. As shown in fig. 2, at this time, the step S102, namely, the step of reducing the heating time and/or the heating power of the health preserving pot according to the anti-overflow signal and the cooking mode of the health preserving pot, may specifically include:

and S1021, when the anti-overflow signal is sent for the first time, performing intermittent heating with first heating power, wherein the first heating power is smaller than preset heating power.

When the health preserving kettle is in a heating state and the anti-overflow signal is sent for the first time, the situation that the heat accumulated by the health preserving kettle is too much by heating with rated heating power before the health preserving kettle is indicated, the heating power can be reduced, and continuous heating is changed into an intermittent heating mode so as to avoid the excessive heat in the kettle body.

And S1022, when the anti-overflow signal is not sent for the first time, carrying out intermittent heating with second heating power, wherein the second heating power is smaller than the heating power when the anti-overflow signal is sent for the last time.

When the overflow-preventing signal is sent out again, the danger of overflow still exists when the first heating power is used for heating. At this time, the heating power or heating time should be continuously adjusted to avoid overheating of the liquid in the kettle body. Specifically, the heating may be performed with a second heating power, where a power value of the second heating power is smaller than the heating power when the anti-overflow signal is sent last time, for example, when the anti-overflow signal is sent for the second time, the power value of the second heating power needs to be lower than the first heating power; when the anti-overflow signal is sent for the third time, the second heating power needs to be further reduced, so that the second heating power is smaller than the heating power when the anti-overflow signal is sent for the second time. By analogy, the health preserving kettle can reduce the heating power once when an anti-overflow signal is sent once, thereby continuously reducing the heat during heating according to the anti-overflow signal and avoiding the overflow phenomenon during heating.

Further, the power value of the second heating power can be equal to the heating power when the anti-overflow signal is sent last minus the first preset power value. Thus, the heating power of the health preserving kettle is reduced by a rated value, namely a first preset power value, every time the anti-overflow signal is sent out. The heating power is in the trend of equal-rate reduction, thereby realizing more accurate control on the heating temperature of the health preserving kettle.

However, since there is a high possibility that boiling water such as health soup overflows, it is necessary to reduce the heating power and the heating time to a large extent. Alternatively, when intermittent heating is performed, the single heating time of the intermittent heating is generally less than the single intermittent time. Therefore, the intermittent time of the intermittent heating in two adjacent times is longer, the accumulation of heat in the kettle body can be effectively reduced, and the anti-overflow effect is better.

Alternatively, when intermittent heating is performed, the single heating time of the intermittent heating generally lasts from about 3 seconds to about 4.5 seconds, and the single intermittent time of the intermittent heating can generally be maintained from about 5 seconds to about 7 seconds. Such intermittent heating frequency, its heating effect is better, can guarantee to have better heating effect to eating the material when avoiding liquid to spill over.

Specifically, the above heating control process is described by a specific example: when the health preserving kettle is normally heated, the preset heating power is 500W, and continuous heating is carried out. When the health preserving kettle sends out the anti-overflow signal for the first time, then reduce heating power to first heating power, specifically 400W to carry out single heating 6 seconds later 10 seconds of intermittent heating process stop again. If the overflow prevention signal is detected again, the heating power is reduced by a first preset power value, for example, 100W, and heating is performed at the reduced power value. When the number of the anti-overflow signals is increased, the heating power value is reduced once, so that the heating power is in a descending state.

In addition, when the health preserving kettle heats with certain heating power and does not send out the anti-overflow signal again for a long time, it indicates that the liquid of the health preserving kettle overflows less, and the heating power can be properly increased or the heating time can be prolonged at the moment so as to accelerate the cooking process of food materials. Fig. 3 is a schematic flow chart of a third heating control method according to an embodiment of the present invention. As shown in fig. 3, as an alternative, after step S1021 or step S1022, the following steps may be further included:

s103, if the difference value between the current time and the sending time of the last anti-overflow signal is larger than a first preset time threshold value, carrying out intermittent heating with third heating power, wherein the third heating power is equal to the sum of the heating power and the accumulated power when the last anti-overflow signal is sent; the accumulated power is the product of the accumulated times and second preset power, and the accumulated times is equal to the ratio of the difference between the current time and the sending time of the last anti-overflow signal to the preset time.

Specifically, if the current time is far from the time of sending the last anti-overflow signal (greater than the first preset time threshold), the intermittent heating process may be performed using a third heating power, which is not a constant value but changes with time. The heating power can be accumulated according to the time difference between the current time and the sending time of the last anti-overflow signal, and the third heating power during heating can be calculated according to the accumulated times and the second preset power. It will be appreciated that the value of the accumulated power will vary from one time to another, and that the accumulated power will increase as the difference between the current time and the time of the last anti-overflow signal increases. Therefore, the counting of the accumulation times can be carried out according to the difference between the current time and the sending time of the last anti-overflow signal. And because the number of times of accumulation is an integer, when the difference is greater than the preset time, the maximum integer less than the ratio between the difference and the preset value can be used as the number of times of accumulation for calculation.

Specifically, the foregoing specific examples are still illustrative. When the heating is performed at the second heating power, for example, 200W, if the current time is after the first preset time threshold, for example, 3 minutes, from the time when the last anti-overflow signal is issued, the intermittent heating is performed at the third heating power. The third heating power is equal to the sum of the heating power when the last anti-overflow signal is sent and the accumulated power. Assuming that the preset time is 3 minutes, the number of times is 1, and the second preset power is 100W, so that the third heating power is 200W +1 x 100W, and the heating can be performed at 300W.

In addition, when the anti-overflow operation is performed, if the heating device does not provide heat for the food in the kettle body, the food is cooled due to heat loss, and then the problems of nutrition loss, taste reduction and the like are caused. Therefore, the health preserving kettle needs to maintain a heating state inside the kettle body all the time so as to preserve heat of food materials. In this case, as an alternative embodiment, the minimum power of the health preserving kettle is always greater than or equal to 100W when heating. Therefore, no matter the health preserving kettle is heated, the power of the health preserving kettle is always larger than or equal to 100W, so that the food materials in the kettle body can be continuously heated, and the problem that the nutrition loss or the taste of the food materials is reduced due to temperature reduction is avoided.

In this embodiment, the heating control method is applied to heating of the health preserving kettle, and specifically includes the following steps: firstly, detecting whether the health preserving kettle sends an anti-overflow signal or not when the health preserving kettle is in a heating state; if the health preserving kettle sends the anti-overflow signal, the heating state of the health preserving kettle is controlled according to the anti-overflow signal and the cooking mode of the health preserving kettle, so that the health preserving kettle realizes anti-overflow heating, wherein different cooking modes correspond to different food materials to be cooked. Can adjust heating state according to the kind of different edible materials like this, produce when avoiding eating the material and cook and spill over, guarantee simultaneously that the material of eating has good effect of cooking.

Example two

When other food materials are cooked in the health preserving kettle, the heating state can also be changed to avoid the liquid in the kettle body from overflowing. Fig. 4 is a schematic flow chart of a fourth heating control method according to the second embodiment of the present invention. As shown in fig. 4, in this embodiment, the cooking mode of the health preserving pot is used for cooking medicated food or fruit tea, and the boiling overflow probability of the health preserving pot is less than that of the health preserving soup, so step S102, that is, the step of reducing the heating time and/or heating power of the health preserving pot according to the overflow preventing signal and the cooking mode of the health preserving pot, may specifically include:

and S1023, when the anti-overflow signal is sent for the first time, continuously heating with fourth heating power, wherein the fourth heating power is smaller than preset heating power.

When the health preserving kettle is in a heating state and the anti-overflow signal is sent for the first time, the situation shows that the heat accumulated by the health preserving kettle heated by the rated heating power is too much, the heating power can be reduced, and the excessive heat in the kettle body is avoided.

And S1024, when the anti-overflow signal is not sent for the first time, continuously heating at a fifth heating power, wherein the fifth heating power is smaller than the heating power when the anti-overflow signal is sent for the last time.

When the overflow prevention signal is sent out again, the danger of overflow still exists when the heating is carried out at the fourth heating power. At this time, the heating power or heating time should be continuously adjusted to avoid overheating of the liquid in the kettle body. Specifically, the heating may be performed at a fifth heating power, and the power value of the fifth heating power is smaller than the heating power when the overflow-preventing signal is sent last time, for example, when the overflow-preventing signal is sent for the second time, the power value of the fifth heating power needs to be lower than the fourth heating power; when the anti-overflow signal is sent for the third time, the fifth heating power needs to be further reduced, so that the fifth heating capacity is smaller than the heating power when the anti-overflow signal is sent for the second time. By analogy, the health preserving kettle can reduce the heating power once when an anti-overflow signal is sent once, thereby continuously reducing the heat during heating according to the anti-overflow signal and avoiding the overflow phenomenon during heating.

Further, the fifth heating power is equal to the heating power when the anti-overflow signal is sent last time minus a third preset power. Thus, the heating power of the health preserving kettle is reduced by a rated value, namely a third preset power value, every time the anti-overflow signal is sent out. The heating power is in the trend of equal-rate reduction, thereby realizing more accurate control on the heating temperature of the health preserving kettle.

The above heating control process is explained still by an example. When the health preserving kettle is normally heated, the preset heating power is 500W, and continuous heating is carried out. When the health preserving kettle sends out the anti-overflow signal for the first time, then reduce heating power to fourth heating power, specifically 400W to carry out the continuous heating. If the overflow prevention signal is detected again, the heating power is reduced by a third preset power value, for example, 100W, and heating is performed at the reduced power value. When the number of the anti-overflow signals is increased, the heating power value is reduced once, so that the heating power is in a descending state.

In addition, when the health preserving pot does not send out the anti-overflow signal again for a long time, it indicates that the liquid of the health preserving pot overflows less, and the heating power can be properly increased at the moment so as to accelerate the cooking process of food materials. Fig. 5 is a schematic flow chart of a fifth heating control method according to the second embodiment of the present invention. As shown in fig. 5, specifically, after step S102, the heating control method may further include:

s104, if the difference value between the current time and the sending time of the last anti-overflow signal is larger than a second preset time threshold value, continuously heating with sixth heating power, wherein the sixth heating power is equal to the sum of the heating power and the accumulated power when the last anti-overflow signal is sent; the accumulated power is the product of a second accumulated time and fourth preset power, and the second accumulated time is equal to the ratio of the difference between the current time and the sending time of the last anti-overflow signal to second preset time.

Specifically, if the current time is far from the sending time of the last anti-overflow signal (greater than the second preset time threshold), the continuous heating may be performed by using the sixth heating power. The heating power can be accumulated according to the time difference between the current time and the sending time of the last anti-overflow signal, and the sixth heating power during heating can be calculated according to the accumulated times and the fourth preset power. It will be appreciated that the value of the accumulated power will vary from one time to another, and that the accumulated power will increase as the difference between the current time and the time of the last anti-overflow signal increases. Therefore, the counting of the accumulation times can be carried out according to the difference between the current time and the sending time of the last anti-overflow signal. And because the number of times of accumulation is an integer, when the difference is greater than the preset time, the maximum integer less than the ratio between the difference and the preset value can be used as the number of times of accumulation for calculation.

Similarly, when the heating is performed at the second heating power, for example, 200W, if the current time is after the time of the last emission of the anti-overflow signal by the second preset time threshold, for example, 3 minutes, the continuous heating is performed at the sixth heating power instead. The sixth heating power is equal to the sum of the heating power and the accumulated power when the last anti-overflow signal is sent. Assuming that the preset time is 3 minutes, the number of times is 1, and the second preset power is 100W, so that the third heating power is 200W +1 x 100W, and the heating can be continued at 300W.

Similarly, in this embodiment, as an alternative, the minimum power of the health preserving kettle during heating is maintained to be greater than or equal to 100W. Therefore, the heat of the food materials in the kettle body can be preserved, and the problem that the nutrition loss or the taste of the food materials is reduced due to temperature reduction is avoided.

In this embodiment, the heating control method specifically includes the following steps: firstly, detecting whether the health preserving kettle sends an anti-overflow signal or not when the health preserving kettle is in a heating state; if the health preserving kettle sends an anti-overflow signal, controlling the heating state of the health preserving kettle according to the anti-overflow signal and the cooking mode of the health preserving kettle, so that the health preserving kettle realizes anti-overflow heating, and different cooking modes are used for correspondingly cooking different food materials; wherein, the heating state of the health preserving kettle is specifically that when the anti-overflow signal is sent for the first time, the health preserving kettle is continuously heated by fourth heating power, and the fourth heating power is less than the preset heating power; and when the anti-overflow signal is not sent for the first time, continuously heating at a fifth heating power, wherein the fifth heating power is smaller than the heating power when the anti-overflow signal is sent for the last time. Like this when the health preserving kettle cook be the medicated diet or fruit tea in, then the adaptability adjust the heating state, produce when avoiding eating the material to cook and spill over, guarantee simultaneously that the material of eating has good effect of cooking.

EXAMPLE III

When the variety cooked by the health preserving kettle is the variety which is not easy to boil and overflow, the health preserving kettle can adopt other heating state changing modes to realize overflow prevention. Fig. 6 is a schematic flow chart of a sixth heating control method according to a third embodiment of the present invention. As shown in fig. 6, in the present embodiment, the cooking mode of the health preserving pot is used for cooking porridge such as health preserving porridge, so the step S102, that is, the step of reducing the heating time and/or heating power of the health preserving pot according to the anti-overflow signal and the cooking mode of the health preserving pot, may specifically include:

s1025, if the duration time of the anti-overflow signal sent by the health preserving kettle exceeds a third preset time threshold value, carrying out intermittent heating with sixth heating power, wherein the sixth heating power is less than the preset heating power.

Specifically, when the health preserving kettle is used for cooking porridge, the porridge contains more solid matters, so that the phenomenon of boiling overflow is not easy to occur, but the phenomenon of bubble wall hanging can occur for a period of time when the porridge is cooked, and the health preserving kettle can continuously send an overflow preventing signal for a long time. In order to avoid that the health preserving kettle adopts wrong boiling-stopping and anti-overflow measures due to the mistaken sending of the anti-overflow signal, the heating mode of the health preserving kettle can be changed when the duration time for sending the anti-overflow signal exceeds a third preset time threshold value, so that the heating mode is intermittently heated by sixth heating power, and porridge and other food materials in the health preserving kettle body are kept in a state to be boiled.

Alternatively, the single heating time of the intermittent heating at the sixth heating power may be less than the single intermittent time. Therefore, the intermittent time of the intermittent heating in two adjacent times is longer, the accumulation of heat in the kettle body can be effectively reduced, and the anti-overflow effect is better.

When the sixth heating power is used for intermittent heating, in order to ensure the heating effect on the porridge while realizing normal overflow prevention, optionally, the single heating time of the intermittent heating with the sixth heating power may be 2 to 4 seconds, and the single intermittent time of the intermittent heating with the sixth heating power may be 8 to 12 seconds. The heating frequency can avoid overflowing of food materials such as porridge in the health preserving kettle, and can also enable the food materials to be heated well, so that good heating and boiling preserving effects are achieved.

The above heating control method is still exemplified by a specific example: when the health preserving kettle is used for normally heating food materials such as health preserving porridge and the like, the preset heating power is 500W, and continuous heating is carried out. When the health preserving kettle sends an anti-overflow signal, and the anti-overflow signal lasts all the time, timing is carried out, if the duration time of the anti-overflow signal exceeds a third preset time threshold value, which can be set to 30 seconds, the heating power is reduced to 300W, namely sixth heating power, and the intermittent heating process of heating for 3 seconds and then stopping for 10 seconds is realized under the power.

Similarly, in this embodiment, similarly to the first and second embodiments, optionally, the minimum power of the health preserving kettle during heating is also greater than or equal to 100W, so as to preserve heat of food materials in the kettle body and avoid loss of nutrition or reduction of taste.

In this embodiment, the heating control method specifically includes the following steps: firstly, detecting whether the health preserving kettle sends an anti-overflow signal or not when the health preserving kettle is in a heating state; if the health preserving kettle sends an anti-overflow signal, controlling the heating state of the health preserving kettle according to the anti-overflow signal and the cooking mode of the health preserving kettle, so that the health preserving kettle realizes anti-overflow heating, and different cooking modes are used for correspondingly cooking different food materials; wherein, the heating state specifically is if the duration that the health preserving kettle sent the anti-overflow signal exceeds the third preset time threshold, then carries out intermittent heating with sixth heating power, and sixth heating power is less than and predetermines heating power. Like this when the health preserving kettle is used for cooking congee such as health preserving congee, the adaptability is adjusted the heating state, produces when avoiding eating the material to cook and spills over, guarantees simultaneously that the material of eating has good effect of cooking.

Example four

The present embodiment further provides a health preserving pot, which is used for executing the heating control method in the first to third embodiments, so as to perform anti-overflow heating control according to the food material variety cooked in the health preserving pot. Fig. 7 is a schematic structural view of a health preserving pot provided by the fourth embodiment of the invention. As shown in fig. 7, the health preserving pot of the embodiment comprises a pot body 1, aheating device 2, ananti-overflow detection device 3 and a controller (not shown in the figure), wherein theheating device 2 is used for heating the inside of the pot body 1, theanti-overflow detection device 3 is used for detecting whether liquid overflows in the pot body 1, theheating device 2 and theanti-overflow detection device 3 are both electrically connected with the controller, and the controller is used for executing a heating control method so as to perform anti-overflow heating control according to food material varieties. The specific process steps of the heating control method have been described in detail in the first to third embodiments, and are not described herein again.

Specifically, the health preserving kettle that this embodiment provided can heat for the internal edible material of kettle through heating device, and wherein, heating device can include dish or heating tube etc. that generates heat. The anti-overflow detection device usually comprises an induction capacitor or an induction resistor and the like, when the liquid level of the liquid in the kettle body rises and the liquid is about to overflow or overflows, the capacitance value or the resistance value of the induction capacitor or the induction resistor changes, so that the anti-overflow detection device can send a signal to the controller, the controller can perform anti-overflow heating control, and the overflow of the liquid in the kettle body is avoided.

In the embodiment, the health preserving pot comprises a pot body, a heating device, an anti-overflow detection device and a controller, wherein the heating device is used for heating the interior of the pot body, the anti-overflow detection device is used for detecting whether liquid overflows from the pot body, the heating device and the anti-overflow detection device are both electrically connected with the controller, and the controller is used for executing a heating control method so as to perform anti-overflow heating control according to food material varieties; the heating control method specifically comprises the following steps: firstly, detecting whether the health preserving kettle sends an anti-overflow signal or not when the health preserving kettle is in a heating state; if the health preserving kettle sends the anti-overflow signal, the heating state of the health preserving kettle is controlled according to the anti-overflow signal and the cooking mode of the health preserving kettle, so that the health preserving kettle realizes anti-overflow heating, and different cooking modes correspond to different food materials to be cooked.
