Description

Cooking appliance

[0001] The present application claims priority to the Chinese Patent Application No. 202410703316.0, filed on May 31, 2024, and titled "Cooking appliance", and the Chinese Patent Application No. 202410703326.4, filed on May 31, 2024, and titled "Cooking appliance", the contents of which are incorporated herein by reference in their entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of household appliances, in particular to a cooking appliance. BACKGROUND

[0003] At present, the cooking appliance usually adopts a moisture removal technology to adjust the baking temperature and humidity, so as to realize various cooking effects such as baking, drying and steaming.

[0004] In the related art, the moisture removal technology is mainly divided into two categories: one is a natural moisture removal technology, which removes water vapor through a ventilation hole on the cooking cavity to maintain the stability of the humidity and temperature inside the cooking cavity. The other is a push door moisture removal technology, which opens the door to increase the air exchange between the cooking cavity and the outside environment to achieve auxiliary moisture removal. In the natural moisture removal technology, the air exchange speed is slow and cannot meet the requirement of moisture removal speed. The response speed of the push door moisture removal technology is slow, and in the case of microwave cooking, the interlocking of the door is abnormally opened, which increases the safety risk. SUMMARY

[0005] The present application aims to at least solve one of the problems in the prior art or related art.

[0006] To this end, the present application provides a cooking appliance.

[0007] Therefore, the present application provides a cooking appliance, which comprises a shell, a fan, and a valve body. The shell comprises a cooking cavity and a mounting cavity. The cooking cavity is provided with an air inlet and an air outlet. The mounting cavity is used for mounting electrical devices. The fan is arranged in the mounting cavity and can send air to the electrical devices to cool the electrical devices. The valve body comprises a valve seat and a valve core. The valve seat comprises a first connecting end and a second connecting end. The first connecting end is in communication with the fan, and the second connecting end is in communication with the air inlet. The valve core is rotatably arranged in the valve seat to have a first state and a second state. When the valve core is in the first state, the channel is in communication with the first connecting end and the second connecting end, and the fan sends air into the cooking cavity through the valve body. When the valve core is in the second state, the fan is disconnected from the cooking cavity.

[0008] The cooking appliance provided in the application comprises a shell, a fan and a valve body. The shell comprises a cooking cavity and a mounting cavity. An electrical device is mounted in the mounting cavity.

[0099] Exemplarily, the rotating drum part 240 is located in the valve seat 23 and rotationally connected with the valve seat 23, the channel 242 is arranged in the rotating drum part 240 and penetrates the rotating drum part 240 along the radial direction of the rotating drum part 240; a part of the connecting part 244 is located in the valve seat 23 and connected with the rotating drum part 240, and another part of the connecting part 244 is located outside the valve seat 23 and connected with the driving member 25, the driving member 25 drives the rotating drum part 240 to rotate around the axis of the rotating drum part 240 through the connecting part 244.

[0100] In this embodiment, the valve core 24 comprises a rotating drum portion 240 and a connecting portion 244 connected with the driving member 25 and the rotating drum portion 240, thereby achieving power transmission. Meanwhile, the connecting portion 244 extends out of the valve seat 23, thereby shortening the length of the output shaft of the driving member 25 and facilitating cost reduction. The rotating drum portion 240 is provided with a channel 242 penetrating the rotating drum portion 240 in the radial direction. The driving member 25 is connected with the rotating drum portion 240 to drive the rotating drum portion 240 to rotate around the axis of the rotating drum portion 240, thereby changing the position of the channel 242 and achieving switching between the first state and the second state. For example, when the valve core 24 is in the first state, the two ends of the channel 242 on the rotating drum portion 240 correspond to the first connecting end 220 and the second connecting end 222 respectively, so that the first connecting end 220 and the second connecting end 222 are connected through the channel 242, and the fan 3 can send air into the cooking cavity 10 through the valve body 22. When the valve core 24 is in the second state, the two ends of the channel 242 are offset from the first connecting end 220 and the second connecting end 222, and the wall surface of the rotating drum portion 240 blocks the first connecting end 220 and the second connecting end 222, so that the first connecting end 220 and the second connecting end 222 are disconnected, thereby preventing the air in the cooking cavity 10 from flowing to the chamber where the fan 3 is located.

[0101] It can be understood that the rotating drum portion 240 has an axis, and the driving member 25 drives the rotating drum portion 240 to rotate around the axis of the rotating drum portion 240, thereby achieving opening and closing of the valve body 22 and reducing the space occupied by the rotating drum portion 240, thereby reducing the occupied space of the valve body 22.

[0102] For example, the driving member 25 can drive the rotating drum portion 240 to rotate 360° along the axis of the rotating drum portion 240.

[0103] For example, the rotating drum portion 240 is a solid cylinder, or the part of the rotating drum portion 240 provided with the channel 242 is a solid structure, and the channel 242 penetrates the part provided with the solid structure.

[0104] It can be understood that the rotating drum portion 240 is in the shape of a cylinder.

[0105] In some embodiments, after the driving member 25 drives the rotary drum part 240 to rotate by a first angle in a first direction about the axis of the rotary drum part 240, the valve core 24 is in the first state, the channel 242 on the rotary drum part 240 is in communication with the first connecting end 220 and the second connecting end 222, and the fan 3 is in conduction with the cooking cavity 10. On the basis that the valve core 24 is in the first state, after the driving member 25 drives the rotary drum part 240 to rotate by a second angle in the first direction, the valve core 24 is in the second state, and the wall surface of the rotary drum part 240 blocks the first connecting end 220 and the second connecting end 222, and the first connecting end 220 and the second connecting end 222 are cut off. The first direction is one of the clockwise direction and the counterclockwise direction of the rotary drum part 240, and the first angle and the second angle can be the same or different. For example, the first angle and the second angle are both 90°.

[0106] In some embodiments, after the driving member 25 drives the rotary drum part 240 to rotate by a third angle in a first direction about the axis of the rotary drum part 240, the valve core 24 is in the first state, the channel 242 on the rotary drum part 240 is in communication with the first connecting end 220 and the second connecting end 222, and the fan 3 is in conduction with the cooking cavity 10. On the basis that the valve core 24 is in the first state, after the driving member 25 drives the rotary drum part 240 to rotate by a third angle in a second direction, the valve core 24 is in the second state, and the wall surface of the rotary drum part 240 blocks the first connecting end 220 and the second connecting end 222, and the first connecting end 220 and the second connecting end 222 are cut off. The first direction and the second direction are opposite. The specific value of the third angle can be set according to actual conditions. For example, the third angle is equal to 90°.

[0107] For example, the output shaft of the driving member 25 is a profiled hole shaft, the connecting part 244 is provided with a profiled hole matched with the profiled hole shaft, and the profiled hole shaft is installed in the profiled hole to achieve power transmission.

[0108] As shown in FIG. 3, in some embodiments, for example, the cooking appliance further comprises: at least two micro switches 7 electrically connected with the driving member 25 and arranged on the valve seat 23. The valve core 24 is provided with a triggering part 246, and the triggering part 246 is located outside the valve seat 23. In the case that the valve core 24 is in the first state, the triggering part 246 triggers at least one micro switch 7, and in the case that the valve core 24 is in the second state, the triggering part 246 triggers another micro switch 7.

[0109] In this embodiment, the cooking appliance further includes at least two microswitches 7. A trigger part 246 is provided on the valve core 24, and the trigger part 246 is disposed opposite to the at least two microswitches 7 to trigger the at least two microswitches 7. Specifically, when the valve core 24 rotates, the trigger part 246 moves with the valve core 24. When the valve core 24 is in a first state, the trigger part 246 triggers at least one microswitch 7 and feeds back to the drive member 25, causing the drive member 25 to control the valve core 24 to remain in a state where the first connection end 220 and the second connection end 222 are connected. When the valve core 24 is in a second state, the trigger part 246 triggers another microswitch 7 and feeds back to the drive member 25, causing the drive member 25 to control the valve core 24 to remain in a state where the first connection end 220 and the second connection end 222 are blocked.

[0110] As shown in Figure 6, in some embodiments, exemplarily, the channel 242 is extended outward from the middle to both ends along the extension direction of the channel 242.

[0111] In this embodiment, the channel 242 is expanded outward from the middle to both ends, so that the area at both ends of the channel 242 is larger. In this way, even if the valve core 24 does not rotate into place or has a slight error, the airflow can still be guaranteed, thereby ensuring the dehumidification speed.

[0112] For example, in a cross section perpendicular to the axis of the roller portion, the included angle between the opposite sides of the channel 242 is 8°.

[0113] It is understandable that when there is a sliding gap error in the micro switch 7, the channel 242 of the rotating drum 240 may not be fully connected with the air guide 6 and the air guide pipe 27, resulting in airflow loss and failure to meet the dehumidification speed requirements. Therefore, the rotating drum 240 adopts a tapered cross-section design to compensate for the trigger gap error of the micro switch 7.

[0114] As shown in Figure 3, in some embodiments, the valve seat 23 includes, by way of example, a seat body 230, a first connecting end 220 and a second connecting end 222 disposed on the seat body 230; and a cover body 232 disposed opposite to and connected to the seat body 230 along the axial direction of the valve core 24.

[0115] In this embodiment, the valve seat 23 includes a seat body 230 and a cover body 232, which are connected together. The valve core 24 is located between the seat body 230 and the cover body 232, thereby limiting the valve core 24. At the same time, the seat body 230 is provided with a first connecting end 220 and a second connecting end 222, which realizes the connection between the fan 3 and the cooking cavity 10.

[0116] As shown in FIG. 1, in some embodiments, the cooking cavity 10 further includes a cooking opening 106, and the exhaust port 104 and the cooking opening 106 are located on the same side of the cooking cavity 10.

[0117] In this embodiment, the exhaust port 104 and the cooking opening 106 are located on the same side of the cooking cavity 10, thereby avoiding the exhaust port 104 being blocked and ensuring the reliability of the dehumidification operation.

[0118] It can be understood that the cooking opening 106 is in communication with the cooking cavity 10, and food materials can be taken in or out of the cooking cavity 10 through the cooking opening 106.

[0119] For example, the exhaust port 104 is located above the cooking opening 106 and exposed to the door body of the cooking appliance, wherein the door body of the cooking appliance is used to open or close the cooking opening 106.

[0120] As shown in FIG. 1, in some embodiments, the fan 3 includes a first air supply port 30 and a second air supply port 32, the first air supply port 30 is used to supply air to the electrical device 5, and the second air supply port 32 is used to supply air to the first connecting end 220.

[0121] In this embodiment, the fan 3 includes the first air supply port 30 and the second air supply port 32, the first air supply port 30 is located opposite to the electrical device 5, so that the fan 3 supplies air to the electrical device 5 through the first air supply port 30, and the second air supply port 32 is in communication with the first connecting end 220, so that the fan 3 supplies air to the cooking cavity 10 through the second air supply port 32. The fan 3 can not only realize heat dissipation of the electrical device 5, but also realize dehumidification of the cooking cavity 10, thereby improving the utilization rate of the fan 3, and reducing the number of parts without additional fans for dehumidification of the cooking cavity 10.

[0122] In some embodiments, for example, the fan 3 includes a cross-flow fan.

[0123] In this embodiment, the fan 3 includes a cross-flow fan, and the cross-flow fan has a large air volume, which can improve the heat dissipation efficiency of the electrical device 5 and the dehumidification speed of the cooking cavity 10.

[0124] For example, the electrical device 5 includes a control device (such as a control panel), a magnetron, a waveguide, a relay, a capacitor, etc.

[0125] For example, the shell 1 further includes a mounting cavity 12, the mounting cavity 12 is located on one side of the cooking cavity 10, and the valve body 22 and the electrical device 5 are arranged in the mounting cavity 12.

[0126] For example, the mounting cavity 12 is located at the top of the cooking cavity 10.

[0127] Exemplarily, the air inlet 102 is arranged on at least one of the top wall of the cooking cavity 10, the side wall of the cooking cavity 10, and the bottom wall of the cooking cavity 10.

[0128] As shown in FIG. 9, in some embodiments, the cooking appliance further comprises a heating member 9 arranged in the housing 1 and configured to supply heat to the cooking cavity 10.

[0129] In this embodiment, the cooking appliance further comprises a heating member 9 configured to supply heat to the cooking cavity 10 to achieve cooking of the food material in the cooking cavity 10.

[0130] In some embodiments, the heating member 9 comprises at least one of a heating tube, a hot air assembly, a steam generator, and a microwave generating portion.

[0131] In this embodiment, the heating tube is capable of radiating heat to the cooking cavity 10 to achieve cooking such as baking of the food material, the hot air assembly is capable of delivering hot air into the cooking cavity 10 to achieve baking of the food material, the steam generator is capable of delivering steam into the cooking cavity 10 to achieve steaming of the food material, and the microwave generating portion is capable of feeding microwaves into the cooking cavity 10 to achieve microwave cooking. The heating member 9 in the present application can be at least one of a heating tube, a hot air assembly, a steam generator, and a microwave generating portion to achieve various cooking modes such as baking, steaming, and drying and combinations of the various cooking modes.

[0132] Exemplarily, in the case where the heating member 9 comprises a microwave generating portion, at least a portion of the microwave generating portion is arranged in the installation cavity 12, the microwave generating portion comprises a magnetron, a waveguide tube, etc., and the fan 3 is capable of dissipating heat from the magnetron, the waveguide tube, etc.

[0133] Exemplarily, in the case where the heating member 9 comprises a steam generator, the steam generator delivers steam into the cooking cavity 10 to achieve steaming of the food material, and the fan 3 and the valve body 22 are further capable of causing the steam after steaming or during steaming to be discharged from the air outlet 104, thereby avoiding the situation that the user is patted in the face by steam when opening the door.

[0134] Exemplarily, the heating member 9 is arranged on at least one of the top, the back, the bottom, and the side wall of the cooking cavity 10.

[0135] In some embodiments, the cooking appliance comprises any one of a microwave oven, an oven, a steamer, a steaming oven, a microwave steaming oven, and an air fryer.

[0136] In this embodiment, the cooking appliance can be any one of a microwave oven, an oven, a steamer, a steaming oven, a microwave steaming oven, and an air fryer to achieve various cooking of the food material such as baking, drying, and steaming.

[0137] In a specific application, the moisture removal structure of the cooking appliance includes the air guide cover 6, the cross-flow fan, and the moisture removal on-off valve (for example, the valve body 22), etc. The air guide cover 6 is connected to the cross-flow fan and the cooking cavity 10, and the exhaust port 104 is arranged obliquely above the cooking cavity 10. The moisture removal structure is mounted on the silica gel pipeline (for example, the air guide pipe 27) of the oven body.

[0138] The moisture removal structure can control the humidity inside the oven by means of the cross-flow fan, thereby achieving various cooking effects such as baking, drying, and steaming. Meanwhile, the cross-flow fan can automatically remove moisture, thereby improving the moisture removal speed.

[0139] The moisture removal structure is assembled on the air guide bottom plate and connected to the cooking cavity 10 through the silica gel pipeline (for example, the air guide pipe 27). The cross-flow fan for cooling is used to inject the airflow of the cross-flow fan into the cooking cavity 10 through the moisture removal on-off valve, and the moisture in the cooking cavity 10 is forcibly squeezed out from the exhaust port 104, thereby achieving airflow exchange and removing the moisture in the cooking cavity 10.

[0140] For example, the moisture removal structure includes the upper air guide cover (for example, the first cover body 64), the lower air guide cover (for example, the second cover body 66), the roller part, the seat body 230, the cover body 232, the alternating current motor, the micro switch 7, the support plate 8, the air guide pipe 27, etc. The roller part is provided with a channel 242 and connected to the seat body 230 and the cover body 232, and can rotate by 360°. The support plate 8 of the cross-flow fan is used to support and fix the cross-flow fan, the air guide cover 6, and the moisture removal on-off valve. The upper air guide cover and the lower air guide cover are connected through buckling and jointly constitute the air guide cover 6, which is used to guide the airflow of the cross-flow fan. The roller part is provided with a cam structure (for example, the trigger part 246) and can trigger the micro switch 7, thereby achieving the fixation and switching of the posture of the roller part. The connecting rod structure (for example, the connecting part 244) is connected to the alternating current motor, and the alternating current motor drives the roller part to rotate through the profiled hole shaft. When moisture removal is needed, the roller part is turned to a state of communication with the cross-flow fan and the air guide pipe 27, thereby blowing the airflow into the cooking cavity 10.

[0141] The air guide cover 6 adopts a design of front wide and rear narrow, upper thick and lower thin, and gentle transition, so as to reduce the wind resistance coefficient, thereby minimizing the airflow loss of the cross-flow fan, so that the airflow injected into the cooking cavity 10 reaches the wind speed requirement of 10 m / s.

[0142] The seat body 230 is provided with a sawtooth-shaped anti-falling structure 224, which has a smooth chamfer design when inserted, thereby saving manpower. When the air guide pipe 27 has a tendency to loosen, the reverse buckle structure increases the sliding resistance, thereby better preventing the air guide pipe 27 from falling off the seat body 230 to cause air leakage.

[0143] The working process of the entire moisture removal structure is as follows:

[0144] When the user selects the menu with the moisture control function, the food is put in and the cooking is started. When the temperature in the cooking cavity 10 rises to the temperature set by the user, the program controls the operation of the moisture removal on-off valve, and the drum part is driven to rotate by the AC motor. Since the air guide cover 6 is always connected to the cross-flow fan, the control of the moisture removal on-off valve rotating to communicate with the air guide cover 6 can inject air flow into the cooking cavity 10. When the channel 242 of the drum part rotates 90° to communicate with the air guide pipe 27, the micro switch 7 is triggered to stop working. At this time, the air flow of the air guide cover 6 is directly communicated with the cooking cavity 10 through the air guide pipe 27, so as to blow the air flow into the cooking cavity 10. When the air flow is continuously injected into the cooking cavity 10, the air pressure in the cooking cavity 10 becomes larger, so that the original moisture in the cooking cavity 10 is forcibly squeezed out from the exhaust port 104, so as to achieve the purpose of reducing the humidity in the cooking cavity 10. When the cooking program runs to the end, the AC motor is started to drive the drum part to rotate 90°. At this time, the micro switch 7 is triggered to stop working, and the channel 242 of the drum part is completely isolated from the air guide pipe 27 and the air guide cover 6, so as to block the cooking cavity 10 and the cross-flow air flow, and the moisture removal function is closed. When the cooking is finished, the user can take out the cooked food by opening the door.

[0145] As shown in FIGS. 10, 11 and 12, according to one embodiment of the present application, the present application provides a cooking appliance, which comprises a shell 1 and a moisture removal assembly 2.

[0146] Exemplarily, the shell 1 comprises a cooking cavity 10 provided with an air inlet 102 and an air outlet 104; the moisture removal assembly 2 is arranged outside the cooking cavity 10, and comprises a blowing unit 20 and a valve body 22. The valve body 22 comprises a first connecting end 220 and a second connecting end 222, the blowing unit 20 is in communication with the first connecting end 220, and the second connecting end 222 is in communication with the air inlet 102. The valve body 22 has an open state and a closed state. In the open state, the first connecting end 220 and the second connecting end 222 are in communication, and the blowing unit 20 can blow air into the cooking cavity 10 through the valve body 22. In the closed state, the first connecting end 220 and the second connecting end 222 are disconnected.

[0147] The cooking appliance provided in the application comprises a shell 1 and a moisture removal assembly 2. The shell 1 comprises a cooking cavity 10 for cooking food. The cooking cavity 10 is provided with an air inlet 102 and an air outlet 104. The moisture removal assembly 2 is arranged on the shell 1 outside the cooking cavity 10. The moisture removal assembly 2 comprises an air supply unit 20 and a valve body 22. The first connecting end 220 of the valve body 22 is arranged opposite to the air supply unit 20. The second connecting end 222 of the valve body 22 is connected to the cooking cavity 10. In the case that the valve body 22 is in an open state, the first connecting end 220, the second connecting end 222 and the air inlet 102 are sequentially communicated. The air supply unit 20 can supply air to the cooking cavity 10 through the valve body 22 and the air inlet 102. As the pressure in the cooking cavity 10 gradually increases, the air in the cooking cavity 10 is discharged through the air outlet 104, realizing moisture removal of the cooking cavity 10 and improving the moisture removal efficiency and safety performance. In the case that the valve body 22 is in a closed state, the first connecting end 220 is disconnected from the second connecting end 222. In this way, the humid hot air in the cooking cavity 10 cannot flow to the position where the air supply unit 20 is located through the valve body 22, avoiding damage to other components of the cooking appliance.

[0148] Exemplarily, the air supply unit 20 refers to a device capable of providing a gas source with a pressure higher than atmospheric pressure, including but not limited to a fan, a blower, an air pump, an air compressor, a high-pressure air pipeline, etc.

[0149] Exemplarily, the air supply unit 20 comprises an air outlet, which is in communication with the first connecting end 220.

[0150] As shown in FIGS. 10 and 11, the direction indicated by the arrow is the flow direction of the air flow.

[0151] As shown in FIGS. 10 and 12, in some embodiments, the valve body 22 comprises a valve seat 23 and a valve core 24.

[0152] Exemplarily, the valve seat 23 comprises the first connecting end 220 and the second connecting end 222. The valve core 24 is rotatably arranged in the valve seat 23, for opening or blocking the first connecting end 220 and the second connecting end 222.

[0153] In this embodiment, the valve body 22 comprises a valve seat 23 and a valve core 24, the valve seat 23 is provided with a first connecting end 220 and a second connecting end 222, the valve core 24 is movably arranged in the valve seat 23 and can rotate in the valve seat 23, thereby enabling the valve body 22 to switch between the open state and the closed state. When the valve body 22 is in the open state, the valve core 24 connects the first connecting end 220 and the second connecting end 222, thereby enabling the air supply unit 20 to supply air into the cooking cavity 10 through the valve body 22 and the air inlet 102, enabling the humid hot air in the cooking cavity 10 to be discharged from the air outlet 104 of the cooking cavity 10, achieving the dehumidification in the cooking cavity 10, thereby improving the cooking effect of the food. When the valve body 22 is in the closed state, the valve core 24 separates the first connecting end 220 and the second connecting end 222, so that the first connecting end 220 and the second connecting end 222 are disconnected, thereby the air supply unit 20 cannot supply air into the cooking cavity 10, and the air in the cooking cavity 10 cannot flow back to the position of the valve body 22 and the air supply unit 20 through the air inlet 102, thereby ensuring the safety performance of other components.

[0154] As shown in FIG. 12, in some embodiments, the valve body 22 further comprises a driving member 25 arranged in the valve seat 23 and connected with the valve core 24, for driving the valve core 24 to rotate in the valve seat 23.

[0155] In this embodiment, the valve body 22 further comprises a driving member 25 arranged in the valve seat 23 and connected with the valve core 24, for driving the valve core 24 to rotate in the valve seat 23, achieving the automatic control of the movement of the valve core 24.

[0156] Exemplarily, the valve core 24 can rotate 360° in the valve seat 23.

[0157] Exemplarily, the cooking appliance further comprises a control device connected with the driving member 25 and the air supply unit 20, and a temperature sensor arranged in the cooking cavity 10 and electrically connected with the control device. When the temperature sensor detects that the temperature in the cooking cavity 10 reaches the set temperature, the control device controls the driving member 25 to drive the valve core 24 to move, so that the first connecting end 220 and the second connecting end 222 are connected, and at the same time, the control device controls the air supply unit 20 to supply air into the cooking cavity 10, achieving the dehumidification in the cooking cavity 10. When the cooking program is running to the end, the control device controls the driving member 25 to drive the valve core 24 to move, so that the first connecting end 220 and the second connecting end 222 are disconnected, and at the same time, the control device controls the air supply unit 20 to stop working.

[0158] Exemplarily, the driving member 25 comprises an electric motor.

[0159] Exemplarily, the driving member 25 comprises an alternating current motor.

[0160] As shown in FIG. 12, in some embodiments, the spool 24 includes a rotating drum 240 rotatably connected with the valve seat 23, the rotating drum 240 is provided with a channel 242 penetrating the rotating drum 240 along a radial direction B of the rotating drum 240, the driving member 25 is connected with the rotating drum 240 for driving the rotating drum 240 to rotate around an axis A of the rotating drum 240, so as to switch the valve body 22 between the open state and the closed state; in the case that the valve body 22 is in the open state, the two ends of the channel 242 are communicated with the first connecting end 220 and the second connecting end 222; in the case that the valve body 22 is in the closed state, the wall surface of the rotating drum 240 blocks the first connecting end 220 and the second connecting end 222.

[0161] In this embodiment, the spool 24 includes the rotating drum 240 provided with the channel 242 penetrating the rotating drum 240 along the radial direction B, the driving member 25 is connected with the rotating drum 240 for driving the rotating drum 240 to rotate around the axis A of the rotating drum 240, so as to change the position of the channel 242, and realize the switching between the open state and the closed state of the valve body 22. For example, in the case that the valve body 22 is in the open state, the two ends of the channel 242 on the rotating drum 240 correspond to the first connecting end 220 and the second connecting end 222 respectively, so that the first connecting end 220 and the second connecting end 222 are communicated through the channel 242, and the air supply unit 20 can supply air into the cooking cavity 10 through the valve body 22; in the case that the valve body 22 is in the closed state, the wall surface of the rotating drum 240 blocks the first connecting end 220 and the second connecting end 222, so that the first connecting end 220 and the second connecting end 222 are disconnected, and the air in the cooking cavity 10 is prevented from flowing to the chamber where the air supply unit 20 is located.

[0162] It can be understood that the rotating drum 240 has an axis A, and the driving member 25 drives the rotating drum 240 to rotate around the axis A of the rotating drum 240, which can realize the opening and closing of the valve body 22, and reduce the space occupied by the rotating drum 240, thereby reducing the occupied space of the valve body 22.

[0163] For example, the driving member 25 can drive the rotating drum 240 to rotate 360° along the axis A of the rotating drum 240.

[0164] For example, the rotating drum 240 is a solid cylinder, or the part of the rotating drum 240 provided with the channel 242 is a solid structure, and the channel 242 penetrates the part where the solid structure is located.

[0165] In some embodiments, after the driving member 25 drives the rotary drum portion 240 to rotate by a first angle in a first direction about the axis A of the rotary drum portion 240, the channel 242 on the rotary drum portion 240 communicates the first connecting end 220 and the second connecting end 222, realizing the conduction between the air supply unit 20 and the cooking cavity 10. On the basis that the valve body 22 is in the open state, after the driving member 25 drives the rotary drum portion 240 to rotate by a second angle in the first direction, the wall surface of the rotary drum portion 240 blocks the first connecting end 220 and the second connecting end 222, realizing the cut-off of the first connecting end 220 and the second connecting end 222. The first angle and the second angle can be the same or different. For example, the first angle and the second angle are both 90°.

[0166] In some embodiments, after the driving member 25 drives the rotary drum portion 240 to rotate by a third angle in a first direction about the axis A of the rotary drum portion 240, the channel 242 on the rotary drum portion 240 communicates the first connecting end 220 and the second connecting end 222, realizing the conduction between the air supply unit 20 and the cooking cavity 10.
