Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.
Referring to fig. 1, conventional air fryers typically use a temperature controller to control the heating temperature. The temperature controller is connected with the heating tube, and when the temperature in the air fryer reaches the target temperature, the heating tube is closed; after a period of time, the temperature in the air fryer is reduced, and the heating tube is opened to make the air fryer reach the target temperature, so that the operation is circulated. However, the control mode controls the on and off of the heating tube through the open circuit and the closed circuit of the relay, so that the heating element has two working states of 0 power and full power, and therefore, the heating amplitude change is large in the whole working process, and the small-amplitude temperature regulation control is not facilitated.
Therefore, different heating powers are adopted in different temperature intervals in the embodiment of the application, so that the variation amplitude of the temperature in the cooking cavity in the working process is reduced. Specifically, when the temperature in the cooking cavity is within a preset temperature interval, the heating device works at the lowest power; when the temperature in the cooking cavity is not within the preset temperature interval, the heating device is operated at 0 power (the heating device is turned off at the moment) or rated power.
In a first aspect, referring to fig. 2 and 3, an embodiment of the present application illustrates a low temperature amplitude control method for an air fryer, where the air fryer includes a temperature measuring device, a heating device, a regulating device and a cooking cavity, the temperature measuring device is used for detecting a temperature in the cooking cavity, the heating device is used for heating the cooking cavity, and the regulating device is used for regulating power of the heating device, and the method includes:
step S1, receiving the temperature T in the cooking cavity sent by the temperature measuring device in real time;
in this embodiment, the temperature measuring device is an NTC temperature sensor, and the NTC thermistor is disposed inside the temperature measuring device, so as to accurately detect the temperature inside the cooking cavity, such as an MF58 type NTC thermistor, whose thermal coefficient is 3950K ± 1%. Because the temperature T in the cooking cavity is in the continuous change process, the NTC temperature sensor detects the temperature T in the cooking cavity in real time and sends the detected temperature value to the control device.
Step S2, determining whether the temperature T is within a preset temperature interval;
in the present embodiment, the air fryer has a predetermined temperature range, which is generally a range around the target temperature; after receiving the detection value of the NTC temperature sensor, the control device determines whether the detection value is within the preset temperature range, and if so, performs step S3.
Step S3, when the temperature T is within the preset temperature interval, controlling the adjusting device to adjust the heating power of the heating device so that the heating device heats the cooking cavity with the lowest power; when the temperature T is within the preset temperature interval, the heating device heats the cooking cavity in an intermittent working mode; the lowest power is the power corresponding to the heating device when the heating device works intermittently.
In this embodiment, the heating device is a mosquito coil type electric heating tube, which is resistant to high temperature, oil and smoke and has a rated power Pe(ii) a The adjusting device is a silicon controlled rectifier which can adjust the heating power of the electric heating tube. When the control device determines that the temperature T in the cooking cavity is within a preset temperature interval, the control device sends a control instruction to the controlled silicon; after the controlled silicon receives the control instruction, the heating power of the electric heating tube is adjusted to be the lowest power, the electric heating tube works in an intermittent heating mode under the power, and the temperature T in the cooking cavity is kept at the target temperature T0Nearby when the temperature in the cooking chamber is at T0The vicinity fluctuates up and down.
Compared with the prior art, in this embodiment, when the temperature T of culinary art chamber was in presetting the temperature interval, adjusting device can be with heating device's heating power adjustment for minimum power, and under this power, heating device works with intermittent type heating's mode, makes the temperature in the culinary art chamber float at the sub-range to the amplitude of air fryer temperature variation in the course of the work has been reduced.
To more vividly illustrate the technical effects of the present embodiment, when the temperature rise coefficient of the cooking cavity is λ, and the temperature of the cooking cavity is T,the operation of the heating tube is P0(ii) a The temperature of the cooking chamber is T0At a time, the power of the heating device is Pe(ii) a When the heating device works intermittently, the corresponding power is PL(ii) a The temperature range of the heating device is Tpp(ii) a When the heating device works intermittently, the starting time and the stopping time are respectively t. When the existing temperature control mode is adopted for controlling the temperature, the temperature amplitude T of the cooking cavitypp=(P0-Pe)λt+(Pe-0)λt=P0λ t; when the temperature is controlled by adopting the low-temperature amplitude control method of the air fryer in the embodiment, the temperature amplitude T of the cooking cavitypp=(P0-Pe)λt+(Pe-PL)λt=(P0-PL)λt<P0λ t. Therefore, when the temperature is controlled by the low-temperature amplitude control method for the air fryer in the embodiment, the temperature change amplitude in the cooking cavity is small, namely the temperature amplitude is small. In an alternative embodiment, in step S2, the preset temperature interval is [ T0,T1]Wherein, T0Is a target temperature, T1To protect the temperature.
In this embodiment, the air fryer is preset with a plurality of cooking modes to adapt to the cooking of different kinds of food, and different cooking modes correspond to different target temperatures T0. At a target temperature T0A protective temperature T is preset nearby1To prevent excessive temperatures within the cooking chamber. When the temperature T in the cooking cavity is in a preset temperature interval T0,T1]During the operation, the SCR adjusts the heating power of the electrothermal tube to the lowest power, and under the power, the heating device works in an intermittent heating mode to enable the temperature in the cooking cavity to float in a small range.
In an alternative embodiment, in step S3, the minimum power is PeB/(a + b), wherein PeAnd a and b are respectively the corresponding shutdown time and startup time when the heating device works intermittently.
In this embodiment, the temperature T of the cooking cavity is within a preset temperature interval T0,T1]When the electric heating tube is used for heating the cooking cavity in an intermittent heating mode, namely starting up, stopping the machine,The system works in a starting-up and stopping way. In general, when an electrothermal tube performs a cycle operation, the shutdown time is a and the startup time is b. In order to ensure the temperature in the cooking cavity to float in a small range, the heating power of the electric heating tube needs to be adjusted to b/(a + b) times of the rated power, i.e. the electric heating tube is PeB/(a + b) power.
In an alternative embodiment, the method for controlling the low temperature web of an air fryer further comprises: at the temperature T being greater than the protection temperature T1And when the temperature is higher than the preset temperature, the heating device is closed.
In this embodiment, when the temperature T in the cooking cavity is greater than the protection temperature T1When the temperature in the cooking cavity is higher than the target temperature T0At this time, in order to avoid the temperature from continuously rising, the electric heating tube needs to be closed to cool the cooking cavity.
In an alternative embodiment, the method for controlling the low temperature web of an air fryer further comprises: at said temperature being less than said target temperature T0While controlling the heating device to rated power PeHeating the cooking cavity.
In this embodiment, when the temperature T in the cooking cavity is less than the target temperature T0If a large amount of heat is needed in the cooking cavity, the electric heating tube needs to be opened to provide heat for the cooking cavity, so that the temperature in the cooking cavity reaches the target temperature T0。
