Thus, the first heating means 310 can be operated only when both the first detectingmeans 410 and the second detecting means determine that thefirst lid assembly 200 is normally fastened. When detecting that firstpot cover subassembly 200 placespot body subassembly 100 on, and firstpot cover subassembly 200 realizes withpot body subassembly 100 that the electricity is connected and has the signal of telecommunication after, just can control the heating offirst heating device 310, can avoid the other pot covers of mistake heating, improve cooking utensil 1's operational reliability and stability like this.

That is to say, through setting upfirst detection device 410 and second detection device, can realize the dual detection to firstpot cover subassembly 200, only when detecting that firstpot cover subassembly 200 is located the on-position state and firstpot cover subassembly 200 is connected withpot body subassembly 100 electricity, just can controlfirst heating device 310 work, improve detection accuracy and reliability to firstpot cover subassembly 200 operating condition, improve cooking utensil 1's safety in utilization and reliability, improve cooking utensil 1's safety in utilization.

Therefore, the cooking appliance 1 according to the embodiment of the invention has the advantages of convenience in use, high working reliability and the like.

A cooking appliance 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

In some embodiments of the present invention, as shown in fig. 1 to 12, a cooking appliance 1 according to an embodiment of the present invention includes apot body assembly 100, a firstpot cover assembly 200, afirst heating device 310, asecond heating device 320, a first detectingdevice 410, a second detecting device 420, and a control device.

In some embodiments of the present invention, the cooking appliance 1 further includes asecond heating device 320, thesecond heating device 320 is disposed on thepot body 110, and the control device controls thesecond heating device 320 not to be operated when thefirst heating device 310 is operated.

In the related art, cooking utensil 1 has two heating element of last heating element and lower heating element, in the use, two heating element exist the condition that heats the food in cooking utensil 1's the culinary art intracavity simultaneously, for example, user's maloperation leads to two heating element simultaneous workings, not only easily lead to food overheat and influence the taste, and easily lead to the inside overheated of pan, make the pan appear the spare part melting, insulating inefficacy, produce the problem such as risk of electrocution, thereby easily appear spare part electric leakage and conflagration risk, and easily appear the power cord, socket and power supply loop current overload and lead to electric leakage and conflagration risk.

Therefore, under the above conditions, the food can be heated only by thefirst heating device 310, the situation that thefirst heating device 310 and thesecond heating device 320 heat simultaneously is prevented, the taste of the food cooking is improved, and the safety risk can be effectively reduced. Meanwhile, the situation that thefirst heating device 310 and thesecond heating device 320 work simultaneously due to the failure of the first detectingdevice 410 or the second detecting device can be avoided, for example, if the user mistakenly covers the firstpot cover assembly 200 on thepot body assembly 100, the control device can control thesecond heating device 320 not to work, so as to prevent the occurrence of safety accidents. Therefore, the phenomenon that parts are fused and insulated due to overheating inside the cooking appliance 1 to cause electric leakage or part ignition risk can be avoided. Meanwhile, the electric shock and fire risks caused by overload of power lines, sockets and power supply loop currents due to overlarge total power can be avoided.

For example, when thesecond heating device 320 works and thefirst lid assembly 200 is not covered on thepot body assembly 100, if thefirst detection device 410 fails to indicate that thefirst lid assembly 200 is fastened, thefirst heating device 310 can be controlled not to work through the detection result of the second detection device, so that thefirst heating device 310 and thesecond heating device 320 can be prevented from working simultaneously.

Optionally, the control device controls thefirst heating device 310 not to work when the first detectingdevice 410 detects that the firstpot lid assembly 200 is in the out-of-position state. Therefore, when the firstpot cover assembly 200 is not buckled on thepot body 110, thefirst heating device 310 is ensured not to work, so that thefirst heating device 310 is prevented from heating in a non-working state of the firstpot cover assembly 200, and the situation that the firstpot cover assembly 200 is burnt or a user is scalded is prevented from occurring.

Here, it should be understood that the "first lid assembly 200 is in the on-position state" means a state that thefirst lid assembly 200 is covered in place on thepot body 110. The "first lid assembly 200 is not in the position" means that thefirst lid assembly 200 is not in the position on thepot body 110.

Optionally, the control device controls thefirst heating device 310 not to work and controls thesecond heating device 320 not to work in a state that thefirst detection device 410 detects that thefirst lid assembly 200 is in the on state and the second detection device detects that thefirst lid assembly 200 is not electrically connected with thepot assembly 100. Specifically, if thefirst detection device 410 fails, thefirst heating device 310 and thesecond heating device 320 may be controlled not to operate, and if the second detection device fails, thefirst heating device 310 and thesecond heating device 320 may be controlled not to operate. Thus, the cooking utensil 1 is convenient to overhaul in time, and larger loss or larger potential safety hazard is avoided.

Further, the cooking appliance 1 further comprises a reminding device, and the control device controls the reminding device to send out reminding information when thefirst detection device 410 detects that thefirst lid assembly 200 is in the in-place state and the second detection device detects that thefirst lid assembly 200 is not electrically connected with thepot assembly 100. Like this can be under the condition that cooking utensil 1 broke down, in time send reminding information through reminding device, convenience of customers in time maintains and handles cooking utensil 1, is convenient for improve cooking utensil 1's intelligence, improves user's use convenience and travelling comfort.

In some embodiments of the present invention, thefirst detection device 410 is adapted to communicate with the control device when thefirst lid assembly 200 is in the in-position state and not communicate with the control device when thefirst lid assembly 200 is in the out-of-position state. Specifically, the communication means of "the first detectingdevice 410 communicates with the control device" includes wired communication and wireless communication. Thus, the control device can control the working states of thefirst heating device 310 and thesecond heating device 320 according to the detection result of thefirst detection device 410, and the working reliability of the cooking appliance 1 is improved.

In some embodiments of the present invention, as shown in fig. 6 or fig. 7, the first detectingdevice 410 includes amicro switch 411 and a movablefitting element 412, themicro switch 411 is disposed on one of thefirst lid assembly 200 or thepan body assembly 100, and themicro switch 411 is electrically connected to the control device. When thefirst cover assembly 200 is covered on thepan body assembly 100, the engagingelement 412 is driven to move to trigger themicro switch 411, and the control device receives a signal of themicro switch 411. That is, themating member 412 is adapted to activate themicro switch 411 when thefirst lid assembly 200 is in the on state, and themating member 412 is adapted not to activate themicro switch 411 when thefirst lid assembly 200 is in the off state. Therefore, when the firstpot cover assembly 200 is buckled, thematching piece 412 triggers themicro switch 411 to enable themicro switch 411 to send a signal to the control device, so that the control device can judge the working state of the firstpot cover assembly 200 according to the received signal of themicro switch 411.

Alternatively, themating element 412 may be formed as a push rod adapted to activate themicro switch 411 when thefirst lid assembly 200 is in the in-position state, the push rod being adapted not to activate themicro switch 411 when thefirst lid assembly 200 is in the out-of-position state.

Specifically,micro switch 411 andmating member 412 are both disposed onpan body assembly 100. This facilitates the installation of the first detectingdevice 410, and facilitates the connection of the first detectingdevice 410 with the control device.

In other embodiments of the present invention, as shown in fig. 8, the first detectingdevice 410 includes a firstmagnetic switch 413 and afirst magnet 414, and the firstmagnetic switch 413 is electrically connected to the control device. Thefirst magnet 414 is in contact with the firstmagnetic switch 413 when thefirst lid assembly 200 is in the on state to trigger the firstmagnetic switch 413, and thefirst magnet 414 is not in contact with the firstmagnetic switch 413 when thefirst lid assembly 200 is in the off state to trigger the firstmagnetic switch 413. Therefore, when the firstpot cover assembly 200 is buckled, thefirst magnet piece 414 is inducted with the first magneticsensitive switch 413 to trigger the first magneticsensitive switch 413, so that the first magneticsensitive switch 413 sends a signal to the control device, and the control device can judge the working state of the firstpot cover assembly 200 according to the received signal of the first magneticsensitive switch 413.

Specifically, one of the firstmagnetic switch 413 and thefirst magnet 414 is disposed on thefirst lid assembly 200 and the other is disposed on thepot assembly 100. This facilitates the first detectingdevice 410 to accurately detect the in-place state of the firstpot lid assembly 200.

More specifically, thefirst magnet 414 is disposed on thefirst lid assembly 200 and the firstmagnetic switch 413 is disposed on thepan assembly 100. This facilitates the installation of the first detectingdevice 410, and facilitates the connection of the first detectingdevice 410 with the control device.

In other embodiments of the present invention, as shown in fig. 9, the first detectingmeans 410 comprises a shielding member, a second magneticsensitive switch 416 and asecond magnet member 417, the shielding member is disposed on one of thefirst cover assembly 200 and thebody assembly 100. The second magneticsensitive switch 416 is adapted to be electrically connected to the control device, and the second magneticsensitive switch 416 and thesecond magnet piece 417 are both disposed on the other of thefirst lid assembly 200 and thepot body assembly 100. Wherein, when thefirst lid assembly 200 is in the on state, the shielding member disconnects the induction between the second magneticsensitive switch 416 and thesecond magnet piece 417 so that the second magneticsensitive switch 416 is not triggered, and when thefirst lid assembly 200 is in the off state, thesecond magnet piece 417 is induced with the second magneticsensitive switch 416 so that the second magneticsensitive switch 416 is triggered. Therefore, when the firstpot cover assembly 200 is buckled, the second magneticsensitive switch 416 is triggered by the shielding member to disconnect the induction between the second magneticsensitive switch 416 and thesecond magnet piece 417, so that the second magneticsensitive switch 416 sends a signal to the control device, and the control device can conveniently judge the working state of the firstpot cover assembly 200 according to the received signal of the second magneticsensitive switch 416.

Optionally, the second magneticallysensitive switch 416 is of a normally closed type and is electrically connected to the control means in a state where the second magneticallysensitive switch 416 is not triggered. This also facilitates the first detecting means 410 to send a signal to the control means when thefirst lid assembly 200 is snapped on.

Of course, the secondmagnetic switch 416 may be a normally open type and electrically connected to the control device in a state where the secondmagnetic switch 416 is activated. That is, the firstpot cover assembly 200 is not triggered when the pot cover is closed, and is in an open state, and at this time, the second magnetic-sensing switch 416 is not electrically connected with the control device, that is, does not send a signal; thefirst lid assembly 200 is triggered when not closed, i.e. in a closed state, and the second magnetic-sensing switch 416 is electrically connected with the control device. Thus, the control device can determine the on-position state of thefirst lid assembly 200 according to the electrical connection state of the second magneticsensitive switch 416, so as to control the working state of the cooking appliance 1.

Specifically, themicro switch 411 is triggered or the magnetic sensitive switch is triggered, wherein "triggered" may mean that themicro switch 411 or the magnetic sensitive switch acts to be in a triggered position, and "not triggered" may mean that themicro switch 411 or the magnetic sensitive switch is in a normal position. For example, the first magneticallysensitive switch 413 may comprise a reed switch, wherein activating the first magneticallysensitive switch 413 means bringing the two reed switches of the first magneticallysensitive switch 413 into attractive contact with each other, and deactivating the first magneticallysensitive switch 413 means that the two reed switches are in a normally non-contact position. For another example, themicro switch 411 includes a movable contact and a fixed contact, the triggering of themicro switch 411 means that the movable contact and the fixed contact of themicro switch 411 are connected, and the non-triggering of themicro switch 411 means that the movable contact and the fixed contact are in a normally open position.

In some embodiments of the present invention, as shown in fig. 4 and 5, the second detection device comprises afirst coupler 421, asecond coupler 422 and adetection sensor 423, wherein thefirst coupler 421 is disposed on thepan body assembly 100. Thesecond coupler 422 is disposed on thefirst lid assembly 200. Thedetection sensor 423 communicates with the control device in a triggered state, thedetection sensor 423 is triggered in a state where thefirst coupler 421 is in electrical communication with thesecond coupler 422, and thedetection sensor 423 is not triggered in a state where thefirst coupler 421 is not in electrical communication with thesecond coupler 422. Therefore, when the firstpot cover assembly 200 is buckled, thedetection sensor 423 is triggered through the electric communication between thefirst coupler 421 and thesecond coupler 422, so that thedetection sensor 423 sends a signal to the control device, and the control device can judge the working state of the firstpot cover assembly 200 according to the received signal of thedetection sensor 423.

Alternatively, thedetection sensor 423 may be a current sensor that detects a current or a voltage sensor that detects a voltage.

Specifically, as shown in fig. 10, the control device includes a microprocessor 510, the microprocessor 510 is respectively in communication with the first detectingdevice 410, the second detecting device, thefirst heating device 310 and thesecond heating device 320, and the microprocessor 510 controls the working states of thefirst heating device 310 and thesecond heating device 320 according to the detection results of the first detectingdevice 410 and the second detecting device. Therefore, the working states of thefirst heating device 310 and thesecond heating device 320 can be controlled in a centralized manner, so that the control accuracy and reliability of the control device can be improved, and the situation that thefirst heating device 310 and thesecond heating device 320 work simultaneously can be avoided.

More specifically, as shown in fig. 10, the control device includes a microprocessor 510, and further includes a first control member 520 and a second control member 530, the first control member 520 is used for controlling the operating state of thefirst heating device 310, the first control member 520 is disposed on thefirst lid assembly 200, and the first control member 520 is in communication with the microprocessor 510 and thefirst heating device 310, respectively. The second control member 530 is used for controlling the working state of thesecond heating device 320, the second control member 530 is disposed on thepot body assembly 100, and the second control member 530 is respectively communicated with the microprocessor 510 and thesecond heating device 320. Thus, the microprocessor 510 can control the operation states of thefirst heating device 310 and thesecond heating device 320 by controlling the operation states of the first control 520 and the second control 530.

Further, the microprocessor 510 is configured and adapted to detect the operation states of the first control 520 and the second control 530, the microprocessor 510 controls the second heating means 320 to be not operated when the first control 520 is detected to be in the failure state, and the microprocessor 510 controls the first heating means 310 to be not operated when the second control 530 is detected to be in the failure state. Thus, in the case where the first control member 520 fails to make the first heating means 310 possible to operate, the opposite second heating means 320 may be controlled not to operate, and in the case where the second control member 530 fails to make the second heating means 320 possible to operate, the opposite first heating means 310 may be controlled not to operate. Thereby, it is possible to avoid the situation that thefirst heating device 310 and thesecond heating device 320 operate simultaneously due to the failure of the first control member 520 or the failure of the second control member 530, and further improve the safety and reliability of the cooking appliance 1.

Alternatively, the first and second controllers 520 and 530 are relays, respectively. Thus, the operating state of the heating apparatus can be controlled by the on/off state of the relay, and the microprocessor 510 can determine whether the relay is out of order according to the on/off state of the relay.

Of course, in other embodiments of the present invention, the control means may include failure detection means, and the microprocessor 510 may detect whether the first and second control members 520 and 530 have failed through the failure detection means.
