Since the cooking utensil is running during cooking, the temperature inside the cooking utensil is high, and the user may cause high-temperature scalding when adding food materials, or the fan and the like in the cooking utensil are running, and the rotating fan may cause harm to the user. SUMMARY

[0003] The utility model aims at least to solve one of the technical problems existing in the prior art or related art.

[0004] Therefore, the utility model provides a cooking utensil.

[0005] Therefore, the utility model provides a cooking utensil.

[0006] The cooking utensil provided by the utility model includes a main body and a cover, wherein the main body includes a cooking space, and the cooking space can be used for placing food materials. The cover is hinged to the main body, that is, the cover and the main body can rotate relative to each other to realize covering the opening of the cooking space of the main body by the cover.

[0007] Further, the cooking utensil can further include a cooking module, which can be used for cooking food materials in the cooking space. Specifically, the cooking module can be a heating device to heat the food materials, or the cooking module can be a microwave device to microwave the food materials, or the cooking module can be a baking device to bake the food materials.

[0008] Further, the cooking utensil can further include a power supply circuit, a first end of the power supply circuit being configured to be connected to the power source, and a second end of the power supply circuit being connected to the cooking module, so that the power supply circuit is configured to transmit the power provided by the power source to the cooking module, to realize the cooking function of the cooking module.

[0009] In the power supply circuit, a switch is included, two ends of the switch being connected to the first end of the power supply circuit and the second end of the power supply circuit respectively, that is, the switch is located between the power source and the cooking module during the operation of the cooking utensil. When the cover does not cover the opening of the cooking space, the switch is in an off state, and when the cover covers the opening of the cooking space, the switch is in an on state.

[0010] That is, during the cooking process of the cooking utensil, if the cover normally covers the opening of the cooking space, the switch is in an on state, and at this time, the power provided by the power source can be normally transmitted to the cooking module through the power supply circuit, to realize the cooking of the food in the cooking space. If the user opens the cover of the cooking utensil during the cooking process, the switch is in an off state at this time, and the power provided by the power source cannot be transmitted to the cooking module, at this time, the cooking module stops running, so that the temperature in the cooking space can gradually decrease, so that the user can add food or seasoning without causing burns to the user. That is, through the setting of the switch in the power supply circuit, the opening detection of the cover of the cooking utensil can be realized, to stop the operation of the cooking module when the cover is opened, to avoid burns caused by high temperature during the cooking process. Compared with the related art which uses a dry reed tube sensor to detect the opening of the cover, the switch has a lower cost, and thus the cost of the cooking utensil can be effectively reduced.

[0011] The cooking utensil provided by the utility model can realize power supply for the cooking module of the cooking utensil through the setting of the power supply circuit, to realize the cooking process of the cooking utensil. At the same time, the switch is set between the first end of the power supply circuit and the second end of the power supply circuit, the switch is disconnected when the cover is opened, to realize the power supply to the cooking module when the cover is opened, at this time, the cooking module stops running, so that the temperature in the cooking space can gradually decrease, so that the user can add food or seasoning without causing burns to the user.

[0012] In addition, the cooking utensil according to the above technical solution provided by the utility model can further have the following additional technical features:

[0013] In some embodiments, the switch member comprises a micro switch, one end of the micro switch is arranged on the main body and connected to the first end of the power supply circuit, the other end of the micro switch is arranged on the cover and connected to the second end of the power supply circuit, wherein when the cover does not cover the opening of the cooking space, the two ends of the micro switch are disconnected, and when the cover covers the opening of the cooking space, the two ends of the micro switch are connected.

[0014] In this embodiment, the switch member can comprise a micro switch, which can be arranged at the connection between the cover and the main body of the cooking appliance, so that the micro switch can switch between being turned on and turned off during the rotation of the cover relative to the main body.

[0015] Specifically, one end of the micro switch is arranged on the main body of the cooking appliance and connected to the first end of the power supply circuit, the other end of the micro switch is arranged on the cover and connected to the second end of the power supply circuit. When the cover covers the opening of the cooking space, the two ends of the micro switch are connected to realize the cooking process of the cooking module. On the contrary, when the cover does not cover the opening of the cooking space, that is, when the cover is opened, the two ends of the micro switch are disconnected, so that the power supply circuit cannot supply power to the cooking module, that is, the cooking process is stopped when the cover is opened.

[0016] In this way, during the cooking process, if the user needs to add food or seasoning, the user can directly open the cover, at this time the two ends of the micro switch are disconnected, the cooking module stops running, and the temperature in the cooking space decreases, avoiding scalding the user.

[0017] In some embodiments, the cooking appliance further comprises a display and control module arranged on the main body for collecting and displaying the cooking parameters of the cooking appliance, wherein the third end of the power supply circuit is connected to the display and control module.

[0018] In this embodiment, the cooking appliance further comprises a display and control module, which can be arranged on the main body of the cooking appliance. Through the display and control module, the cooking parameters of the cooking appliance can be collected and displayed during the cooking process, so that the user can view the cooking parameters during the cooking process to improve the user's cooking experience. The first end of the power supply circuit is used to connect to the power source, and the second end of the power supply circuit is connected to the display and control module, so that the power supply provided by the power supply circuit is transmitted to the display and control module to ensure the normal operation of the display and control module.

[0019] Further, by the setting of the switch piece in the power supply circuit, the opening detection of the cover of the cooking utensil can be realized, so as to stop the operation of the cooking module when the cover is opened, to avoid the high temperature in the cooking process from causing scalding to the user. Compared with the opening detection by using a dry reed sensor in the related art, the switch piece has a lower cost, and thus the cost of the cooking utensil can be effectively reduced. Meanwhile, since the switch piece is arranged between the first end and the second end of the power supply circuit, that is, between the power supply and the cooking module, in the case that the switch piece is disconnected, the power supply to the display and control module of the cooking utensil will not be affected. In this way, even if the user opens the cover during the cooking process, the display and control module can still continue to retain the current cooking progress and cooking parameters, and after the user closes the cover, the cooking utensil can still continue the incomplete cooking process.

[0024] In this technical solution, the conversion assembly can comprise a power supply chip and a voltage reduction module. One end of the power supply chip is connected to the voltage stabilizing and filtering assembly, which can be used to receive the high-voltage alternating current output by the voltage stabilizing and filtering assembly. Through the power supply chip, the received high-voltage alternating current can be converted into high-voltage direct current, so as to realize the conversion between alternating current and direct current, and specifically, the high-voltage alternating current can be converted into 12V high-voltage direct current.

[0025] Further, one end of the voltage reduction module is connected to the power supply chip, and can receive high-voltage direct current output by the power supply chip. After receiving the high-voltage direct current, the voltage reduction module can reduce the voltage of the high-voltage direct current, thereby converting the high-voltage direct current into low-voltage direct current. The other end of the voltage reduction module is connected to the display and control module, thereby transmitting the low-voltage direct current to the display and control module, so as to provide the required low-voltage direct current for the display and control module.

[0028] Specifically, the heating unit is connected to the voltage stabilizing and filtering assembly. The voltage stabilizing and filtering assembly is configured to stabilize and filter the alternating current provided by the alternating current power supply, and then transmit the stabilized and filtered electric energy to the heating unit, so that the heating unit generates heat when powered on, thereby achieving the heating function.

[0029] In addition, the switch of the power supply circuit is located between the voltage stabilizing and filtering assembly and the heating unit. When the user opens the cover, the switch is disconnected, so that the voltage stabilizing and filtering assembly and the heating unit are disconnected. At this time, the heating unit is no longer powered on, thereby stopping heating and preventing the user from being scalded by high temperature when opening the cover.

[0030] In some embodiments, the cooking module further comprises a driving unit arranged in the cover and connected to the voltage stabilizing and filtering assembly.

[0032] Specifically, the driving unit can be arranged on the cover body, so that the driving unit can be opposite to the opening of the cooking space, and thus the gas in the cooking space can be driven. Meanwhile, the driving unit is connected to the voltage stabilizing and filtering assembly, so that the voltage stabilizing and filtering assembly can transmit the voltage-stabilized and filtered electric energy to the driving unit to meet the operation requirement of the driving unit.

[0033] In addition, the switch of the power supply circuit is located between the voltage stabilizing and filtering assembly and the driving unit. When the user opens the cover body, the switch is disconnected, so that the voltage stabilizing and filtering assembly and the driving unit are disconnected. At this time, the driving unit is no longer powered, and thus the driving of the gas can be stopped, which can avoid the user from being scalded by high temperature after opening the cover body, and can also avoid the user's hand from being injured by the rotation of the fan blade during the operation of the driving unit.

[0034] In some technical solutions, the driving unit comprises: a motor arranged on the cover body; and a fan blade connected to the output end of the motor, the fan blade being opposite to the cooking space. The power supply circuit further comprises: a rectifier unit, one end of the rectifier unit being connected to the voltage stabilizing and filtering assembly, and the other end of the rectifier unit being connected to the motor, the rectifier unit being configured to rectify the alternating current to drive the motor to operate, and the switch being located between the voltage stabilizing and filtering assembly and the rectifier unit.

[0035] In this technical solution, the driving unit can comprise a motor and a fan blade, the motor is arranged on the cover body of the cooking utensil, and the fan blade is connected to the output end of the motor. Through the motor, the fan blade can be driven to rotate. Meanwhile, the fan blade is opposite to the opening of the cooking space, and the gas in the cooking space can be driven during the rotation of the fan blade.

[0036] Further, the power supply circuit further comprises a rectifier unit, one end of the rectifier unit being connected to the voltage stabilizing and filtering assembly, and the other end of the rectifier unit being connected to the motor. Through the arrangement of the rectifier unit, the alternating current output by the voltage stabilizing and filtering assembly can be converted into direct current required by the motor to operate, so as to ensure the normal operation of the motor.

[0037] In addition, the switch of the power supply circuit is located between the voltage stabilizing and filtering assembly and the rectifier unit. When the user opens the cover body, the switch is disconnected, so that the voltage stabilizing and filtering assembly and the rectifier unit are disconnected. At this time, the motor is no longer powered, and thus the driving of the gas can be stopped, which can avoid the user from being scalded by high temperature after opening the cover body, and can also avoid the user's hand from being injured by the continuous rotation of the fan blade.

[0038] In some embodiments, the display and control module comprises a control unit connected to the other end of the conversion assembly, the control unit is further connected to the motor; a sampling circuit, one end of the sampling circuit is connected to the display and control module, and the other end of the sampling circuit is connected to the voltage stabilizing and filtering assembly; the sampling circuit is configured to collect a first voltage signal of the voltage stabilizing and filtering assembly when the cover does not cover the opening of the cooking space, and the control unit is configured to control the output shaft of the motor to stop rotating when the first voltage signal is received.

[0040] Further, the two ends of the sampling circuit are respectively connected to the control unit and the voltage stabilizing and filtering assembly, and the sampling circuit can be used to collect the voltage signal of the voltage stabilizing and filtering assembly. It can be understood that, according to the on and off states of the switch, the voltage stabilizing and filtering assembly can simultaneously supply power to the display and control module and the cooking module, or can supply power to the display and control module alone. In the two power supply modes, the voltage stabilizing and filtering assembly can generate different voltage signals. By collecting the voltage signal of the voltage stabilizing and filtering assembly through the sampling circuit, the control unit can determine the current power supply state of the voltage stabilizing and filtering assembly.

[0041] Specifically, when the cover does not cover the opening of the cooking space, that is, when the cover is opened, at this time, the voltage stabilizing and filtering assembly supplies power to the display and control module alone.

[0044] In some embodiments, the display and control module comprises a display unit connected to the control unit, and the control unit is configured to control the display unit to display the cooking parameters of the cooking appliance.

[0045] In this embodiment, the display and control module further comprises a display unit connected to the control unit, so that the control unit can control the display unit to display the cooking parameters after obtaining the cooking parameters of the cooking appliance.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0055] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the protection scope of the present application is not limited by the specific embodiments disclosed below.

[0056] The following description refers to the accompanying drawings that show embodiments of the present application. Figures 1 to 4 A cooking appliance according to some embodiments of the present application is described.

[0057] According to the present application, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a cooking appliance 100 is provided, comprising: a main body 102, the main body 102 comprising a cooking space 104; a cover body 106, the cover body 106 being hinged to the main body 102, for covering an opening 150 of the cooking space 104; a cooking module 110, the cooking module 110 being arranged on the main body 102 and / or the cover body 106, for cooking food materials in the cooking space 104; a power supply circuit 112, a first end of the power supply circuit 112 being used for connecting to a power source 200, a second end of the power supply circuit 112 being connected to the cooking module 110, the power supply circuit 112 comprising: a switch piece 116, two ends of the switch piece 116 being respectively connected to the first end of the power supply circuit 112 and the second end of the power supply circuit 112; wherein, in a case that the cover body 106 does not cover the opening 150 of the cooking space 104, the switch piece 116 is in an off state, and in a case that the cover body 106 covers the opening 150 of the cooking space 104, the switch piece 116 is in a conduction state.

[0058] The cooking appliance 100 provided by the present application comprises a main body 102 and a cover body 106, wherein the main body 102 comprises a cooking space 104, and the cooking space 104 can be used for placing food materials. The cover body 106 is hinged to the main body 102, that is, the cover body 106 and the main body 102 can rotate relative to each other, so as to cover the opening 150 of the cooking space 104 of the main body 102 by the cover body 106.

[0059] Further, the cooking appliance 100 can further include a cooking module 110, which can be used to cook the food materials in the cooking space 104. Specifically, the cooking module 110 can be a heating device to heat the food materials, or the cooking module 110 can be a microwave device to microwave the food materials, or the cooking module 110 can be a baking device to bake the food materials.

[0060] Further, the cooking appliance 100 can further include a power supply circuit 112, a first end of the power supply circuit 112 being configured to be connected to the power source 200, and a second end of the power supply circuit 112 being connected to the cooking module 110, so as to transmit the electric energy provided by the power source 200 to the cooking module 110 through the power supply circuit 112, to realize the cooking function of the cooking module 110.

[0061] Specifically, the power supply circuit 112 includes a switch 116, two ends of the switch 116 being connected to the first end of the power supply circuit 112 and the third end of the power supply circuit 112 respectively, that is, the switch 116 is located between the power source 200 and the cooking module 110 during the operation of the cooking appliance 100. In addition, when the cover 106 does not cover the opening 150 of the cooking space 104, the switch 116 is in an off state, and conversely, when the cover 106 covers the opening 150 of the cooking space 104, the switch 116 is in an on state.

[0062] That is, during the cooking process of the cooking appliance 100, if the cover 106 normally covers the opening 150 of the cooking space 104, the switch 116 is in an on state, and at this time, the electric energy provided by the power source 200 can be normally transmitted to the cooking module 110 through the power supply circuit 112, to realize the cooking of the food materials in the cooking space 104. If the user opens the cover 106 of the cooking appliance 100 during the cooking process, at this time, the switch 116 is in an off state, and the electric energy provided by the power source 200 cannot be transmitted to the cooking module 110, at this time, the cooking module 110 stops running, so that the temperature in the cooking space 104 can gradually decrease, so that the user can add food materials or seasonings without causing burns to the user. That is, through the arrangement of the switch 116 in the power supply circuit 112, the opening detection of the cover 106 of the cooking appliance 100 can be realized, so as to stop the operation of the cooking module 110 when the cover 106 is opened, to avoid burns to the user caused by high temperature during the cooking process. Compared with the related art which uses a dry reed tube sensor to detect the opening of the cover, the switch 116 has a lower cost, and thus the cost of the cooking appliance 100 can be effectively reduced.

[0063] Specifically, the switch piece 116 can be a switch tube, two ends of the switch tube are connected to the first end and the third end of the power supply circuit 112 respectively, and a control end of the switch tube can be used to collect the cover opening signal, that is, in the process of opening or closing the cover 106 by the user, the signal of the control end of the switch tube changes, so as to control the conduction state between the two ends of the switch tube. Alternatively, the switch tube can also be a photoelectric switch, which realizes the switching of the conduction state of the two ends of the switch piece 116 through the change of light, for example, when the cover 106 is opened, the photoelectric switch can receive light, at this time the photoelectric switch can be in an open state, on the contrary, after the cover 106 is closed, the photoelectric switch cannot receive light, and the two ends of the photoelectric switch are in a conduction state.

[0064] The cooking appliance 100 provided by the utility model can realize power supply for the cooking module 110 of the cooking appliance 100 through the setting of the power supply circuit 112, and further realize the cooking process of the cooking appliance 100. Meanwhile, the switch piece 116 is arranged between the first end of the power supply circuit 112 and the second end of the power supply circuit 112, the switch piece 116 is disconnected when the cover 106 is opened, so that the power supply to the cooking module 110 is stopped when the cover 106 is opened, at this time the cooking module 110 stops running, so that the temperature in the cooking space 104 can gradually decrease, so that the user can add food materials or seasonings without causing scalding to the user.

[0065] In some embodiments, optionally, as shown in Figure 4 The switch piece 116 includes: a micro switch 118, one end of the micro switch 118 is arranged on the main body 102 and connected to the first end of the power supply circuit 112, and the other end of the micro switch 118 is arranged on the cover 106 and connected to the second end of the power supply circuit 112; wherein, in the case that the cover 106 does not cover the opening 150 of the cooking space 104, the two ends of the micro switch 118 are disconnected, and in the case that the cover 106 covers the opening 150 of the cooking space 104, the two ends of the micro switch 118 are connected.

[0066] In this embodiment, the switch piece 116 can include a micro switch 118, and the micro switch 118 can be arranged at the connection between the cover 106 and the main body 102 of the cooking appliance 100, so that the micro switch 118 can realize the switching of conduction and cut-off in the process of rotating the cover 106 relative to the main body 102.

[0067] Specifically, one end of the micro switch 118 is arranged on the main body 102 of the cooking utensil 100 and connected to the first end of the power supply circuit 112, and the other end of the micro switch 118 is arranged on the cover body and connected to the second end of the power supply circuit 112. In the case that the cover body 106 covers the opening 150 of the cooking space 104, the two ends of the micro switch 118 are in conduction to realize the cooking process of the cooking module 110. On the contrary, in the case that the cover body 106 does not cover the opening 150 of the cooking space 104, that is, in the case that the cover body 106 is opened, the two ends of the micro switch 118 are disconnected, so that the power supply circuit 112 cannot supply power to the cooking module 110, that is, the cooking process is stopped in the case that the cover body 106 is opened.

[0068] In this way, during the cooking process, if the user needs to add food materials or seasonings, the user can directly open the cover body 106, at this time, the two ends of the micro switch 118 are disconnected, the cooking module 110 stops running, and the temperature in the cooking space 104 decreases, avoiding scalding the user.

[0069] In some embodiments, optionally, as shown in Figure 2 The cooking utensil further comprises a display and control module arranged on the main body, for collecting and displaying the cooking parameters of the cooking utensil; wherein the third end of the power supply circuit is connected to the display and control module.

[0070] In this embodiment, the cooking utensil 100 further comprises a display and control module 108, which can be arranged on the main body 102 of the cooking utensil 100. Through the display and control module 108, the cooking parameters of the cooking utensil 100 can be collected and displayed during the cooking process, so that the user can view the cooking parameters during the cooking process to improve the user's cooking experience. The first end of the power supply circuit 112 is used to be connected to the power source 200, and the second end of the power supply circuit 112 is connected to the display and control module 108, so as to transmit the electric energy provided by the power source 200 to the display and control module 108 through the power supply circuit 112, to ensure the normal operation of the display and control module 108.

[0071] Further, by the arrangement of the switch piece 116 in the power supply circuit 112, the opening detection of the cover 106 of the cooking utensil 100 can be realized, so as to stop the operation of the cooking module 110 when the cover 106 is opened, to avoid the high temperature in the cooking process from causing burns to the user. Compared with the related art which uses a dry reed tube sensor to detect the opening of the cover, the switch piece 116 has a lower cost, and thus the cost of the cooking utensil 100 can be effectively reduced. Meanwhile, since the switch piece 116 is arranged between the first end and the third end of the power supply circuit 112, that is, between the power source 200 and the cooking module 110, in the case where the switch piece 116 is disconnected, the power source 200 will not be affected to supply power to the display and control module 108 of the cooking utensil 100. In this way, even if the user opens the cover 106 during the cooking process, the display and control module 108 can still continue to retain the current cooking progress and cooking parameters, and after the user closes the cover 106, the cooking utensil 100 can still continue the unfinished cooking process.

[0072] In some embodiments, optionally, the power supply circuit 112 further includes a voltage stabilizing and filtering assembly 120, the voltage stabilizing and filtering assembly 120 is connected to the power source 200; a conversion assembly 122, one end of the conversion assembly 122 is connected to the voltage stabilizing and filtering assembly 120, and the other end of the conversion assembly 122 is connected to the display and control module 108, the conversion assembly 122 is used to convert high-voltage alternating current into low-voltage direct current.

[0073] In this embodiment, the power supply circuit 112 can further include the voltage stabilizing and filtering assembly 120, by which the voltage stabilizing and filtering assembly 120 can stabilize and filter the power provided by the power source 200, to ensure the quality of the power input to the display and control module 108 and the cooking module 110, so as to ensure that the display and control module 108 and the cooking module 110 can normally and stably operate.

[0074] Specifically, the voltage stabilizing and filtering assembly 120 can include a voltage stabilizing and filtering module 146 and a plurality of diodes 148. It can be understood that the cooking utensil is usually connected to alternating current, the current direction and voltage of the alternating current usually change periodically, and interference waves are generated during current transmission. The voltage stabilizing and filtering module 146 can stabilize the voltage and filter the interference waves in the current. By arranging the plurality of diodes 148, based on the unidirectional conduction characteristic of the diodes 148, the flow direction of the current can be controlled and the interference waves can be filtered in one step.

[0075] Further, the power supply circuit 112 further comprises a conversion assembly 122, through which the high-voltage alternating current can be converted into low-voltage direct current, so as to provide the low-voltage direct current for the display control module 108, and meet the normal operation requirement of the display control module 108. It can be understood that the display control module 108 usually needs 5V low-voltage direct current, therefore, the conversion assembly 122 can convert the high-voltage alternating current provided by the alternating current power supply into 5V low-voltage direct current, so as to meet the operation requirement of the display control module 108. Specifically, one end of the conversion assembly 122 is connected to the voltage stabilizing and filtering assembly 120, and the other end of the conversion assembly 122 is connected to the display control module 108.

[0076] In some embodiments, as shown in Figure 4 , the conversion assembly 122 comprises a power supply chip 124, one end of the power supply chip 124 is connected to the voltage stabilizing and filtering assembly 120, and the power supply chip 124 is used for converting alternating current into direct current; a voltage reduction module 126, one end of the voltage reduction module 126 is connected to the power supply chip 124, and the other end of the voltage reduction module 126 is connected to the display control module 108, and the voltage reduction module 126 is used for converting high-voltage direct current into low-voltage direct current.

[0077] In this embodiment, the conversion assembly 122 can comprise the power supply chip 124 and the voltage reduction module 126, wherein one end of the power supply chip 124 is connected to the voltage stabilizing and filtering assembly 120, and can be used for receiving the high-voltage alternating current output by the voltage stabilizing and filtering assembly 120, and through the power supply chip 124, the received high-voltage alternating current can be converted into high-voltage direct current, so as to realize the conversion between alternating current and direct current, and specifically, the high-voltage alternating current can be converted into 12V high-voltage direct current.

[0078] Further, one end of the voltage reduction module 126 is connected to the power supply chip 124, and can receive the high-voltage direct current output by the power supply chip 124, and after receiving the high-voltage direct current, the voltage reduction module 126 can reduce the voltage of the high-voltage direct current, so as to convert the high-voltage direct current into low-voltage direct current, and specifically, the 12V high-voltage direct current can be converted into 5V low-voltage direct current. And the other end of the voltage reduction module 126 is connected to the display control module 108, so as to transmit the low-voltage direct current to the display control module 108, so as to provide the required low-voltage direct current for the display control module 108.

[0079] In some embodiments, as shown in Figure 2 , Figure 3 and Figure 4 , the cooking module 110 comprises a heating unit 128, which is arranged in the main body 102, and the heating unit 128 is connected to the voltage stabilizing and filtering assembly 120, and the heating unit 128 is used for heating in the case of power-on, so as to heat the food materials in the cooking space 104, wherein the switch piece 116 is located between the voltage stabilizing and filtering assembly 120 and the heating unit 128.

[0080] In this embodiment, the cooking module 110 can include a heating unit 128, and the heating unit 128 can be arranged in the main body 102 of the cooking appliance, and the heating unit 128 can generate heat when powered on to heat the cooking space 104 in the main body 102, thereby achieving the heating and cooking of the food materials in the cooking space 104. The heating unit 128 can be a resistive load, such as an electric heating wire, to generate heat when powered on.

[0081] Specifically, the heating unit 128 can be connected to the voltage stabilizing and filtering assembly 120, so that the voltage stabilizing and filtering assembly 120 can stabilize and filter the alternating current provided by the alternating current power supply, and then transmit the stabilized and filtered electrical energy to the heating unit 128, so that the heating unit 128 generates heat when powered on to achieve the heating function.

[0082] In addition, the switch 116 of the power supply circuit 112 is located between the voltage stabilizing and filtering assembly 120 and the heating unit 128. When the user opens the cover 106, the switch 116 is disconnected, so that the voltage stabilizing and filtering unit and the heating unit 128 are disconnected, and at this time the heating unit 128 is no longer powered on, thereby stopping heating to avoid the user being scalded by high temperature after opening the cover 106.

[0083] Further, as shown in Figure 2 The cooking module 110 further includes a driving unit 130 arranged in the cover 106 and connected to the voltage stabilizing and filtering assembly 120, the driving unit 130 is opposite to the cooking space 104 and is used to drive the gas flow in the cooking space 104; wherein the switch 116 is located between the voltage stabilizing and filtering assembly 120 and the driving unit 130.

[0084] Specifically, the cooking module 110 can further include a driving unit 130, which can be used to drive the gas in the cooking space 104, so as to drive the high-temperature gas in the cooking process to flow in the cooking space 104, thereby improving the uniformity of heating the food materials. For example, in the steam and oven integrated machine, during the process of steaming or baking the food materials in the cooking space 104 by the high-temperature gas, the high-temperature gas is driven by the driving unit 130 at the same time, so that the contact between the food materials and the high-temperature gas is more uniform, thereby improving the steaming and baking efficiency and effect of the steam and oven integrated machine.

[0085] Specifically, the driving unit 130 can be arranged on the cover 106, so that the driving unit 130 can be opposite to the opening 150 of the cooking space 104, and thus the gas in the cooking space 104 can be driven. Meanwhile, the driving unit 130 is connected to the voltage stabilizing and filtering assembly 120, so that the voltage stabilizing and filtering assembly 120 can transmit the voltage-stabilized and filtered electric energy to the driving unit 130 to meet the operation requirement of the driving unit 130.

[0086] In addition, the switch 116 of the power supply circuit 112 is located between the voltage stabilizing and filtering assembly 120 and the driving unit 130. When the user opens the cover 106, the switch 116 is disconnected, so that the voltage stabilizing and filtering assembly 120 and the driving unit 130 are disconnected. At this time, the driving unit 130 is no longer powered, and thus the driving of the gas can be stopped. This can avoid the user from being scalded by high temperature after opening the cover 106, and can also avoid the user's hand from being injured during the operation of the driving unit 130.

[0087] In some embodiments, as shown in Figure 3 and Figure 4 The driving unit 130 includes a motor 132 arranged on the cover 106, and a fan blade 134 connected to the output end of the motor 132. The fan blade 134 is opposite to the cooking space 104. The power supply circuit 112 further includes a rectifier unit 136, one end of the rectifier unit 136 being connected to the voltage stabilizing and filtering assembly 120, and the other end of the rectifier unit 136 being connected to the motor 132. The rectifier unit 136 is used to rectify the alternating current to drive the motor 132 to operate. The switch 116 is located between the voltage stabilizing and filtering assembly 120 and the rectifier unit 136.

[0088] In this embodiment, the driving unit 130 can include the motor 132 and the fan blade 134. The motor 132 is arranged on the cover 106 of the cooking appliance 100. The fan blade 134 is connected to the output end of the motor 132. Through the motor 132, the fan blade 134 can be driven to rotate. Meanwhile, the fan blade 134 is opposite to the opening 150 of the cooking space 104. During the rotation of the fan blade 134, the gas in the cooking space 104 can be driven.

[0090] In addition, the switch 116 of the power supply circuit 112 is located between the voltage stabilizing filter assembly 120 and the rectifier unit 136. When the user opens the cover 106, the switch 116 is turned off, so that the voltage stabilizing filter assembly is disconnected with the rectifier unit 136. At this time, the motor 132 is no longer powered, and the driving of the gas is stopped, thereby avoiding the user from being scalded by high temperature after opening the cover 106, and avoiding the fan blade 134 from continuing to rotate to cause injury to the user's hand.

[0093] Further, the two ends of the sampling circuit 140 are connected to the control unit 138 and the voltage stabilizing filter assembly 120, respectively. The sampling circuit 140 can be used to collect the voltage signal of the voltage stabilizing filter assembly 120. It can be understood that, according to the on and off states of the switch 116, the voltage stabilizing filter assembly 120 can supply power to the control module 108 and the cooking module 110 at the same time, or supply power to the control module 108 alone. In the two power supply modes, the voltage stabilizing filter assembly 120 can generate different voltage signals. By collecting the voltage signal of the voltage stabilizing filter assembly 120 through the sampling circuit 140, the control unit 138 can determine the current power supply state of the voltage stabilizing filter assembly 120.

[0094] Specifically, in the case that the cover 106 does not cover the opening 150 of the cooking space 104, that is, in the case that the cover 106 is opened, at this time, the voltage stabilizing and filtering assembly 120 supplies power to the display and control module 108 alone, at this time, the sampling circuit 140 can collect the first voltage signal of the display and control module 108 and transmit the first voltage signal to the control unit 138. Moreover, the control unit 138 is connected with the motor 132 of the driving unit 130, and the control unit 138 can determine that the cover 106 is opened at this time when the first voltage signal is received, and the user can need to add food or seasoning to the cooking space 104, and the control unit 138 can control the output end of the motor 132 of the driving unit 130 to stop rotating immediately, so as to make the fan blade 134 of the driving unit 130 stop rotating immediately, thereby avoiding that the user is injured by the fan blade 134 continuing to rotate due to inertia after the cover 106 is opened.
