[0001] This invention relates to the field of household appliance technology, and more specifically, to a cooking appliance and its control method, apparatus, electronic device, and readable storage medium. Background Technology

[0002] Currently, cooking appliances using this technology generate a large amount of steam when the user opens the oven door after cooking, causing steam to hit their face, affecting the user experience and posing a risk of burns. Additionally, a large amount of condensation accumulates inside the steam oven after cooking, making cleaning inconvenient. Summary of the Invention

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

[0004] Therefore, a first aspect of the present invention provides a method for controlling a cooking appliance.

[0005] A second aspect of the present invention also provides a control device for a cooking appliance.

[0006] A third aspect of the invention also provides a cooking utensil.

[0007] A fourth aspect of the present invention also provides an electronic device.

[0008] A fifth aspect of the invention also provides a readable storage medium.

[0009] In view of this, a first aspect of the present invention provides a control method for a cooking appliance. The control method is used for a cooking appliance, which includes a housing and a steam exhaust assembly. The housing includes a cooking cavity, which has an air inlet and an exhaust port. The steam exhaust assembly includes an air supply unit and a valve body. The valve body includes a first connecting end and a second connecting end. The air supply unit is connected to the first connecting end, and the second connecting end is connected to the air inlet. When the valve body is in an open state, the first connecting end and the second connecting end are connected, and the air supply unit can supply air into the cooking cavity through the valve body. When the valve body is in a closed state, the first connecting end and the second connecting end are disconnected. The control method includes: acquiring the cooking state of the cooking appliance; and when the cooking appliance has finished cooking, controlling the air supply unit and the valve body to open, so that the air supply unit supplies air into the cooking cavity through the valve body, and the cooking cavity exhausts steam through the exhaust port.

[0010] The present invention provides a control method for a cooking appliance, which includes a housing and a steam exhaust assembly. The housing includes a cooking cavity for cooking food. The cooking cavity has an air inlet and an exhaust outlet. The steam exhaust assembly includes an air supply unit and a valve body. A first connection end of the valve body is opposite to the air supply unit, and a second connection end of the valve body is connected to the cooking cavity through the air inlet. The control method includes: acquiring the cooking state of the cooking appliance; when the cooking appliance has completed cooking, controlling the air supply unit and the valve body to open, thereby connecting the first connection end, the second connection end, and the air inlet in sequence. The air supply unit can supply air into the cooking cavity through the valve body and the air inlet. As the pressure inside the cooking cavity gradually increases, the air inside the cooking cavity is quickly discharged through the exhaust outlet, realizing the exhaust of steam or moisture from the cooking appliance, improving exhaust efficiency and safety performance, and preventing users from being scalded by hot air when opening the door. Furthermore, during steam cooking, the reduced amount of steam within the cooking chamber leads to less steam condensation after cooking, resulting in less condensation at the bottom of the chamber and reducing the hassle of cleaning accumulated water. Simultaneously, with the valve closed, the first and second connections are disconnected, preventing air from flowing through the valve to the air supply unit and avoiding damage to other components of the cooking appliance, thus ensuring the reliability of the cooking process.

[0011] The control method for cooking appliances provided by the present invention may also have the following additional technical features:

[0012] In some embodiments, optionally, the step of controlling the opening of the air supply unit and the valve body when the cooking appliance has finished cooking includes: controlling the air supply unit to open based on the cooking status being that cooking is complete; and opening the valve body after the air supply unit has been running for a first period of time.

[0013] In this embodiment, when cooking is complete, the air supply unit is turned on first, and then the valve body is opened after the air supply unit has been running for a first period of time. This can prevent the steam or moisture in the cooking cavity from flowing back through the valve body, thereby ensuring the reliability of steam or moisture discharge and preventing the air supply unit from being damaged if steam or moisture flows back into the air supply unit.

[0014] In some embodiments, optionally, the valve body includes a valve seat, a valve core, and a drive member. The valve seat includes a first connecting end and a second connecting end. The valve core is rotatably disposed within the valve seat and is used to connect or block the first connecting end and the second connecting end. The drive member is disposed within the valve seat and connected to the valve core, and is used to drive the valve core to rotate within the valve seat. The step of opening the valve body includes: controlling the drive member to operate so that the drive member drives the valve core to rotate, and the first connecting end and the second connecting end are connected.

[0015] In this embodiment, the valve body includes a valve seat, a valve core, and a drive component. The valve seat has a first connecting end and a second connecting end. The valve core is movably disposed within the valve seat and can rotate within the valve seat, thereby enabling the valve body to switch between an open state and a closed state. The step of opening the valve body includes controlling the drive component to operate, causing the drive component to drive the valve core to rotate, thereby connecting the valve core with the first connecting end and the second connecting end, allowing the air supply unit to supply air into the cooking cavity through the first connecting end and the second connecting end.

[0016] In some embodiments, optionally, the valve core is provided with a triggering part, and the exhaust assembly further includes a first micro switch, the first micro switch being electrically connected to the drive member, and the triggering part being disposed opposite to the first micro switch for triggering the first micro switch and controlling the drive member to work so that the drive member drives the valve core to rotate, the step of which includes: turning on the drive member so that the valve core rotates along a first direction and drives the triggering part to rotate; and turning off the drive member when the triggering part triggers the first micro switch.

[0017] In this embodiment, a trigger part is provided on the valve core, and the exhaust assembly includes a first micro switch. The first micro switch is electrically connected to the drive member and is disposed opposite to the trigger part. The step of controlling the drive member to work so that the valve core rotates includes controlling the valve core to rotate in a first direction so that the trigger part on the valve core rotates with the valve core. When the trigger part triggers the first micro switch, the drive member stops working, so that the valve core remains in the open state.

[0018] In some embodiments, the steam venting assembly may optionally include a second micro switch, which is electrically connected to the drive member. A triggering part is disposed opposite to the second micro switch and is used to trigger the second micro switch. The control method further includes: determining whether the cooking cavity has completed steam venting; if the cooking cavity has completed steam venting, controlling the drive member to open so that the valve core rotates in a second direction and drives the triggering part to rotate; if the triggering part triggers the second micro switch, closing the drive member so that the valve core blocks the first connection end and the second connection end; the first direction is opposite to the second direction.

[0019] In this embodiment, the steam exhaust assembly further includes a second micro switch, which is electrically connected to the drive unit and disposed opposite to the trigger unit. The control method further includes: determining whether the cooking cavity has completed steam exhaust; if the cooking cavity has completed the steam exhaust operation, the valve body needs to be closed; at this time, the drive unit is controlled to work, causing the valve core to rotate in the second direction, thereby driving the trigger unit to rotate in the second direction with the valve core; when the trigger unit triggers the second micro switch, it indicates that the valve core has rotated to the correct position, thereby closing the drive unit, stopping the drive on the valve core, keeping the valve core in the closed state, disconnecting the first connection end and the second connection end, and resetting the entire machine.

[0020] In some embodiments, the cooking appliance may optionally include a door for opening or closing the cooking cavity. The step of determining whether the cooking cavity has completed venting includes: obtaining opening information of the door and confirming that the cooking cavity has completed venting based on the door being in an open state; or obtaining the running time of the venting component and confirming that the cooking cavity has completed venting based on the running time being greater than or equal to a target time.

[0021] In this embodiment, determining whether the cooking cavity has completed venting can be done by detecting the running time of the venting component or by observing the opening and closing status of the door. Specifically, if the door is open, confirming that the cooking cavity has completed venting prevents continued airflow into the cooking cavity from causing airflow to flow out of the door and directly hit the user's face, affecting the user experience; or, if the venting component has run for the target duration, confirming that the cooking cavity has completed venting prevents prolonged airflow from causing the food inside the cooking cavity to cool down.

[0022] In some embodiments, optionally, after the step of shutting down the drive, the method further includes: shutting down the air supply unit while the drive has been shut down for a second period of time.

[0023] In this embodiment, after confirming that the cooking cavity has completed steam venting, the air supply unit is turned off after the second time period of the drive unit is turned off, so as to ensure that the air supply unit is turned off only after the valve body is completely closed, thereby preventing the hot air in the cooking cavity from flowing to the location of the air supply unit.

[0024] According to a second aspect of the present invention, a control device for a cooking appliance is also provided. The cooking appliance includes a housing and a steam exhaust assembly. The housing includes a cooking cavity with an air inlet and an exhaust port. The steam exhaust assembly includes an air supply unit and a valve body. The valve body includes a first connecting end and a second connecting end. The air supply unit is connected to the first connecting end, and the second connecting end is connected to the air inlet. When the valve body is in an open state, the first connecting end and the second connecting end are connected, and the air supply unit can supply air into the cooking cavity through the valve body. When the valve body is in a closed state, the first connecting end and the second connecting end are disconnected. The control device includes: an acquisition unit for acquiring the cooking state of the cooking appliance; and a control unit for controlling the air supply unit and the valve body to open when the cooking appliance has finished cooking, so that the air supply unit supplies air into the cooking cavity through the valve body, and the cooking cavity exhausts steam through the exhaust port.

[0025] The second aspect of this invention provides a control device for a cooking appliance. The cooking appliance includes a housing and a steam exhaust assembly. The housing includes a cooking cavity for cooking food. The cooking cavity has an air inlet and an exhaust outlet. The steam exhaust assembly includes an air supply unit and a valve body. A first connecting end of the valve body is opposite to the air supply unit, and a second connecting end of the valve body is connected to the cooking cavity. The control device includes an acquisition unit and a control unit. The acquisition unit acquires the cooking status of the cooking appliance, and the control unit controls the air supply unit and the valve body to open when the cooking appliance has finished cooking. This allows the first connecting end, the second connecting end, and the air inlet to connect sequentially. The air supply unit can supply air into the cooking cavity through the valve body and the air inlet. As the pressure inside the cooking cavity gradually increases, the air inside the cooking cavity is quickly discharged through the exhaust outlet, achieving steam or moisture removal from the cooking appliance. This improves exhaust efficiency and safety performance, preventing users from being scalded by hot air when opening the door. Furthermore, during steam cooking, the reduced amount of steam within the cooking chamber leads to less steam condensation after cooking, resulting in less condensation at the bottom of the chamber and reducing the hassle of cleaning accumulated water. Simultaneously, with the valve closed, the first and second connections are disconnected, preventing air from flowing through the valve to the air supply unit and avoiding damage to other components of the cooking appliance, thus ensuring the reliability of the cooking process.

[0026] According to a third aspect of the present invention, a cooking appliance is also provided, comprising: a housing, the housing including a cooking cavity having an air inlet and an exhaust outlet; an exhaust assembly disposed outside the cooking cavity, the exhaust assembly including an air supply unit and a valve body, the valve body including a first connecting end and a second connecting end, the air supply unit communicating with the first connecting end, and the second connecting end communicating with the air inlet; the valve body having an open state and a closed state, wherein when the valve body is in the open state, the first connecting end and the second connecting end are connected, and the air supply unit can supply air into the cooking cavity through the valve body; and when the valve body is in the closed state, the first connecting end and the second connecting end are disconnected; and a control device as described in the second aspect.

[0027] The cooking appliance provided in the third aspect of the present invention includes a housing, a steam exhaust assembly, and a control device. The housing includes a cooking cavity for cooking food. The cooking cavity has an air inlet and an exhaust outlet. The steam exhaust assembly is disposed on the housing outside the cooking cavity. The steam exhaust assembly includes an air supply unit and a valve body. A first connecting end of the valve body is disposed opposite to the air supply unit, and a second connecting end of the valve body is connected to the cooking cavity. Thus, when the valve body is in the open state, the first connecting end, the second connecting end, and the air inlet are sequentially connected, and the air supply unit can supply air into the cooking cavity through the valve body and the air inlet. As the pressure inside the cooking cavity gradually increases, the air inside the cooking cavity is discharged through the exhaust outlet, realizing the steam exhaust of the cooking cavity and improving the steam exhaust efficiency and safety performance. When the valve body is in the closed state, the first connecting end and the second connecting end are disconnected, so that the hot and humid air inside the cooking cavity cannot flow to the location of the air supply unit through the valve body, avoiding damage to other components of the cooking appliance. Meanwhile, the control device can regulate the ventilation components to supply air to the cooking cavity based on the cooking status of the appliance. This allows for the removal of steam or moisture, improving ventilation efficiency and safety, and preventing scalding from hot air when the door is opened. Furthermore, in steam cooking, the reduced amount of steam within the cooking cavity leads to less condensation after cooking, resulting in less water accumulation at the bottom of the cavity and reducing the hassle of cleaning away condensation.

[0028] In some embodiments, the valve body may optionally include: a valve seat, the valve seat including a first connecting end and a second connecting end; a valve core, rotatably disposed within the valve seat, for connecting or blocking the first connecting end and the second connecting end; and a driving member, disposed within the valve seat and connected to the valve core, for driving the valve core to rotate within the valve seat.

[0029] In this embodiment, the valve body includes a valve seat, a valve core, and a driving component. The valve seat has a first connecting end and a second connecting end. The valve core is movably disposed within the valve seat and can rotate within the valve seat. The driving component can drive the valve core to rotate, thereby allowing the valve body to switch between an open state and a closed state. When the valve body is in the open state, the valve core connects the first connecting end and the second connecting end, allowing the air supply unit to supply air into the cooking cavity through the valve body and the air inlet. This allows the humid and hot air in the cooking cavity to be discharged through the steam outlet of the cooking cavity, achieving dehumidification or steam removal from the cooking cavity, thereby improving the cooking effect on the food. When the valve body is in the closed state, the valve core separates the first connecting end and the second connecting end, disconnecting the connection between the two connecting ends. This prevents the air supply unit from supplying air into the cooking cavity, and the air in the cooking cavity cannot flow back to the valve body and the location of the air supply unit through the air inlet, thus ensuring the safety performance of other components.

[0030] In some embodiments, the exhaust assembly may optionally include: a first micro switch disposed on a valve seat and electrically connected to a drive member, wherein a trigger portion is provided on the valve core, and the first micro switch is located on one side of the trigger portion along a first direction; and a second micro switch disposed on a valve seat and electrically connected to a drive member, wherein a trigger portion is provided on the valve core, and the second micro switch is located on one side of the trigger portion along a second direction; when the trigger portion triggers the first micro switch, the drive member is closed and the valve body is in an open state; when the trigger portion triggers the second micro switch, the drive member is closed and the valve body is in a closed state.

[0031] In this embodiment, the exhaust assembly further includes a first microswitch and a second microswitch. A triggering part is provided on the valve core, and the triggering part is disposed opposite to the first and second microswitches to trigger them. Specifically, when the driving member drives the valve core to rotate in a first direction, the triggering part moves with the valve core. When the triggering part triggers the first microswitch, a signal is fed back to the driving member, causing the driving member to stop moving and controlling the valve core to remain in a state where the first and second connection ends are connected. When the driving member drives the valve core to rotate in a second direction, the triggering part moves relative to the valve core. When the triggering part triggers the second microswitch, a signal is fed back to the driving member, causing the driving member to control the valve core to remain in a state where the first and second connection ends are blocked.

[0032] In some embodiments, the valve core may optionally include: a rotating cylinder portion rotatably connected to a valve seat, the rotating cylinder portion having a channel extending radially through the rotating cylinder portion, a drive member connected to the rotating cylinder portion for driving the rotating cylinder portion to rotate around the axis of the rotating cylinder portion, so as to switch the valve body between an open state and a closed state; when the valve body is in the open state, the two ends of the channel are connected to a first connection end and a second connection end; when the valve body is in the closed state, the wall of the rotating cylinder portion blocks the first connection end and the second connection end.

[0033] In this embodiment, the valve core includes a rotating cylinder with a radially penetrating channel. A driving member is connected to the rotating cylinder to drive it to rotate around its axis, thereby changing the position of the channel and switching between the open and closed states of the valve body. Specifically, when the valve body is in the open state, the two ends of the channel on the rotating cylinder correspond to a first connecting end and a second connecting end, respectively, allowing the first and second connecting ends to be connected through the channel, enabling the air supply unit to supply air into the cooking cavity through the valve body. When the valve body is in the closed state, the wall of the rotating cylinder blocks the first and second connecting ends, disconnecting the connection between them and preventing air from flowing into the chamber where the air supply unit is located.

[0034] In some embodiments, the valve core may optionally include: a connecting portion, a part of which is located inside the valve seat and connected to the rotating drum portion, and another part of which extends to the outside of the valve seat and is connected to the driving member, the driving member driving the rotating drum portion to rotate through the connecting portion, and a trigger portion located at one end of the connecting portion located outside the valve seat.

[0035] In this embodiment, the valve core also includes a connecting portion, which connects to the drive component and the rotating drum portion, thereby realizing power transmission. Simultaneously, by extending the connecting portion out of the valve seat, the length of the output shaft on the drive component is shortened, which helps reduce costs. A trigger portion is located at the end of the connecting portion located outside the valve seat to trigger the first and second microswitches.

[0036] In some embodiments, the cooking appliance may optionally include: an electrical component, the housing further including a mounting cavity located on one side of the cooking cavity, a steam exhaust assembly disposed within the mounting cavity, and the electrical component disposed within the mounting cavity; and a cooling fan disposed within the mounting cavity for dissipating heat from the electrical component.

[0037] In this embodiment, the cooking appliance also includes electrical components and a cooling fan. The exhaust assembly, the cooling fan, and the electrical components are all disposed within the mounting cavity. The cooling fan is used to blow air to the electrical components to dissipate heat from the electrical components within the mounting cavity, thereby improving the working performance of the electrical components. By placing the exhaust assembly within the mounting cavity, the space occupied by the exhaust assembly in the cooking appliance is reduced.

[0038] In some embodiments, the cooking appliance may optionally include a door, the cooking cavity further including a cooking opening, the door for opening or closing the cooking opening, and the vent and the cooking opening being located on the same side of the cooking cavity.

[0039] In this embodiment, the vent and the cooking opening are located on the same side of the cooking cavity, thereby avoiding the vent being blocked and ensuring the reliability of the dehumidification operation.

[0040] In some embodiments, the vent is optionally located at the top of the cooking opening; and / or the vent is disposed near at least one of the opposite side walls of the cooking cavity.

[0041] In this embodiment, the vent can be located at the top of the cooking opening to avoid scalding the user. The vent can be located near one of the opposite sides of the cooking cavity; optionally, the vent is located at the upper left or upper right of the cooking cavity.

[0042] In some embodiments, the cooking appliance may optionally include a heating element disposed in the housing for heating the cooking cavity.

[0043] In this embodiment, the cooking appliance also includes a heating element for heating the cooking cavity to cook the food inside the cooking cavity.

[0044] In some embodiments, the heating element may optionally include at least one of a heating tube, a hot air assembly, a steam generator, and a microwave generator.

[0045] In this embodiment, the heating element radiates heat into the cooking cavity to achieve cooking such as grilling; the hot air assembly delivers hot air into the cooking cavity to achieve grilling; the steam generator delivers steam into the cooking cavity to achieve steaming; and the microwave generator feeds microwaves into the cooking cavity to achieve microwave cooking. The heating element in this application can be at least one of a heating element, a hot air assembly, a steam generator, and a microwave generator to achieve various cooking methods such as grilling, steaming, and drying, as well as combinations of these methods.

[0046] In some embodiments, the cooking appliance may optionally include any one of a microwave oven, oven, steam oven, steam oven, microwave-steam-roaster, or air fryer.

[0047] In this embodiment, the cooking appliance can be any one of a microwave oven, oven, steam oven, steam oven, microwave-steam-roast machine, or air fryer.

[0061] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0062] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0063] The following reference Figures 1 to 7 This invention describes cooking appliances, control methods, apparatuses, electronic devices, and readable storage media according to some embodiments of the invention.

[0064] like Figure 1 , Figure 2 and Figure 4 As shown, according to an embodiment of the present invention, the present invention proposes a control method for a cooking appliance. The control method is used for a cooking appliance, which includes a housing and a steam exhaust assembly. The housing includes a cooking cavity, which is provided with an air inlet and an exhaust outlet. The steam exhaust assembly includes an air supply unit and a valve body. The valve body includes a first connecting end and a second connecting end. The air supply unit is connected to the first connecting end, and the second connecting end is connected to the air inlet. When the valve body is in the open state, the first connecting end and the second connecting end are connected, and the air supply unit can supply air into the cooking cavity through the valve body. When the valve body is in the closed state, the first connecting end and the second connecting end are disconnected.

[0065] like Figure 4 The diagram shows a flowchart of a control method for a cooking appliance, which includes:

[0066] Step 602: Obtain the cooking status of the cooking utensils;

[0067] Step 604: When the cooking appliance has finished cooking, control the air supply unit and valve body to open, so that the air supply unit supplies air into the cooking cavity through the valve body, and the cooking cavity exhausts steam through the exhaust port.

[0068] The present invention provides a control method for a cooking appliance, which includes a housing and a steam exhaust assembly. The housing includes a cooking cavity for cooking food. The cooking cavity has an air inlet and an exhaust outlet. The steam exhaust assembly includes an air supply unit and a valve body. A first connection end of the valve body is opposite to the air supply unit, and a second connection end of the valve body is connected to the cooking cavity through the air inlet. The control method includes: acquiring the cooking state of the cooking appliance; when the cooking appliance has completed cooking, controlling the air supply unit and the valve body to open, thereby connecting the first connection end, the second connection end, and the air inlet in sequence. The air supply unit can supply air into the cooking cavity through the valve body and the air inlet. As the pressure inside the cooking cavity gradually increases, the air inside the cooking cavity is quickly discharged through the exhaust outlet, realizing the exhaust of steam or moisture from the cooking appliance, improving exhaust efficiency and safety performance, and preventing users from being scalded by hot air when opening the door. Furthermore, during steam cooking, the reduced amount of steam within the cooking chamber leads to less steam condensation after cooking, resulting in less condensation at the bottom of the chamber and reducing the hassle of cleaning accumulated water. Simultaneously, with the valve closed, the first and second connections are disconnected, preventing air from flowing through the valve to the air supply unit and avoiding damage to other components of the cooking appliance, thus ensuring the reliability of the cooking process.

[0069] Optionally, the cooking appliance includes a heating element, which includes a steam generator, enabling steam cooking of food inside the cooking cavity.

[0070] In some embodiments, optionally, the step of controlling the opening of the air supply unit and the valve body when the cooking appliance has finished cooking includes: controlling the air supply unit to open based on the cooking status being that cooking is complete; and opening the valve body after the air supply unit has been running for a first period of time.

[0071] In this embodiment, when cooking is complete, the air supply unit is turned on first, and then the valve body is opened after the air supply unit has been running for a first period of time. This can prevent the steam or moisture in the cooking cavity from flowing back through the valve body, thereby ensuring the reliability of steam or moisture discharge and preventing the air supply unit from being damaged if steam or moisture flows back into the air supply unit.

[0072] Optionally, the first duration is greater than or equal to 2 seconds and less than or equal to 10 seconds.

[0073] Optionally, the first duration can be any value among 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, and 10s.

[0074] In some embodiments, optionally, the valve body includes a valve seat, a valve core, and a drive member. The valve seat includes a first connecting end and a second connecting end. The valve core is rotatably disposed within the valve seat and is used to connect or block the first connecting end and the second connecting end. The drive member is disposed within the valve seat and connected to the valve core, and is used to drive the valve core to rotate within the valve seat. The step of opening the valve body includes: controlling the drive member to operate so that the drive member drives the valve core to rotate, and the first connecting end and the second connecting end are connected.

[0075] In this embodiment, the valve body includes a valve seat, a valve core, and a drive component. The valve seat has a first connecting end and a second connecting end. The valve core is movably disposed within the valve seat and can rotate within the valve seat, thereby enabling the valve body to switch between an open state and a closed state. The step of opening the valve body includes controlling the drive component to operate, causing the drive component to drive the valve core to rotate, thereby connecting the valve core with the first connecting end and the second connecting end, allowing the air supply unit to supply air into the cooking cavity through the first connecting end and the second connecting end.

[0076] In some embodiments, optionally, the valve core is provided with a triggering part, and the exhaust assembly further includes a first micro switch, the first micro switch being electrically connected to the drive member, and the triggering part being disposed opposite to the first micro switch for triggering the first micro switch and controlling the drive member to work so that the drive member drives the valve core to rotate, the step of which includes: turning on the drive member so that the valve core rotates along a first direction and drives the triggering part to rotate; and turning off the drive member when the triggering part triggers the first micro switch.

[0077] In this embodiment, a trigger part is provided on the valve core, and the exhaust assembly includes a first micro switch. The first micro switch is electrically connected to the drive member and is disposed opposite to the trigger part. The step of controlling the drive member to work so that the valve core rotates includes controlling the valve core to rotate in a first direction so that the trigger part on the valve core rotates with the valve core. When the trigger part triggers the first micro switch, the drive member stops working, so that the valve core remains in the open state.

[0078] In some embodiments, the steam venting assembly may optionally include a second micro switch, which is electrically connected to the drive member. A triggering part is disposed opposite to the second micro switch and is used to trigger the second micro switch. The control method further includes: determining whether the cooking cavity has completed steam venting; if the cooking cavity has completed steam venting, controlling the drive member to open so that the valve core rotates in a second direction and drives the triggering part to rotate; if the triggering part triggers the second micro switch, closing the drive member so that the valve core blocks the first connection end and the second connection end; the first direction is opposite to the second direction.

[0079] In this embodiment, the steam exhaust assembly further includes a second micro switch, which is electrically connected to the drive unit and disposed opposite to the trigger unit. The control method further includes: determining whether the cooking cavity has completed steam exhaust; if the cooking cavity has completed the steam exhaust operation, the valve body needs to be closed; at this time, the drive unit is controlled to work, causing the valve core to rotate in the second direction, thereby driving the trigger unit to rotate in the second direction with the valve core; when the trigger unit triggers the second micro switch, it indicates that the valve core has rotated to the correct position, thereby closing the drive unit, stopping the drive on the valve core, keeping the valve core in the closed state, disconnecting the first connection end and the second connection end, and resetting the entire machine.

[0080] It is understandable that the angle by which the valve core rotates in the first direction during the opening process is the same as the angle by which the valve core rotates in the second direction during the closing process.

[0081] Specifically, along the circumferential rotation of the valve core, the triggering part is located between the first micro switch and the second micro switch. Thus, when the valve core rotates in the first direction and reaches its position, the first micro switch is triggered, and when the valve core rotates in the second direction and reaches its position, the second micro switch is triggered.

[0082] In some embodiments, the cooking appliance may optionally include a door for opening or closing the cooking cavity. The step of determining whether the cooking cavity has completed venting includes: obtaining opening information of the door and confirming that the cooking cavity has completed venting based on the door being in an open state; or obtaining the running time of the venting component and confirming that the cooking cavity has completed venting based on the running time being greater than or equal to a target time.

[0083] In this embodiment, determining whether the cooking cavity has completed venting can be done by detecting the running time of the venting component or by observing the opening and closing status of the door. Specifically, if the door is open, confirming that the cooking cavity has completed venting prevents continued airflow into the cooking cavity from causing airflow to flow out of the door and directly hit the user's face, affecting the user experience; or, if the venting component has run for the target duration, confirming that the cooking cavity has completed venting prevents prolonged airflow from causing the food inside the cooking cavity to cool down.

[0084] Understandably, the target duration can be set according to the actual situation, such as any value between 1 minute and 20 minutes.

[0085] In some embodiments, optionally, after the step of shutting down the drive, the method further includes: shutting down the air supply unit while the drive has been shut down for a second period of time.

[0086] In this embodiment, after confirming that the cooking cavity has completed steam venting, the air supply unit is turned off after the second time period of the drive unit is turned off, so as to ensure that the air supply unit is turned off only after the valve body is completely closed, thereby preventing the hot air in the cooking cavity from flowing to the location of the air supply unit.

[0087] Specifically, such as Figure 5 The diagram shows a flowchart of a control method for a cooking appliance, which includes:

[0088] Step 702: Steam cooking is complete;

[0089] Step 704: The control device issues a steam exhaust command;

[0090] Step 706: Start the DC fan;

[0091] Step 708: The AC motor starts running;

[0092] Step 710: Determine whether the first micro switch has been triggered. If yes, proceed to step 712; otherwise, return to step 708.

[0093] Step 712: The AC motor stops;

[0094] Step 714: The exhaust assembly is turned on to exhaust steam;

[0095] Step 716: Steam venting complete;

[0096] Step 718: The AC motor starts running;

[0097] Step 720: Determine whether the second micro switch is triggered. If yes, proceed to step 722; otherwise, return to step 718.

[0098] Step 722: The AC motor stops;

[0099] Step 724: Turn off the DC fan;

[0100] Step 726: The venting assembly is closed, the oven door can be opened, there is no condensation or water splashing onto the face.

[0101] The entire exhaust assembly operates as follows:

[0102] After the user finishes steam cooking, the program control activates the exhaust component. A DC fan (e.g., an air supply unit) is driven by an AC motor (e.g., a drive unit). After a 5-second delay, the AC motor drives the valve core to rotate. The first microswitch is triggered, and the AC motor stops. At this point, the DC fan is directly connected to the cooking cavity, generating airflow that blows into the cavity. As airflow continues to enter the cavity, the pressure increases, forcibly expelling steam from the exhaust port. This reduces the amount of steam in the cavity, so that when the user opens the door, they can barely feel any steam, effectively eliminating the risk of steam hitting their face and causing burns. The reduced steam volume also reduces condensation after cooking, decreasing the amount of water accumulating at the bottom of the cavity and alleviating the hassle of cleaning accumulated water.

[0103] When the user opens the door or releases steam for a specific period of time, the AC motor starts, driving the valve core to rotate. At this time, the trigger unit activates the second microswitch, stopping the AC motor and thus blocking the airflow between the cooking cavity and the DC fan. After a 5-second delay, the DC fan stops working, the steam release function is turned off, and the entire unit resets.

[0104] like Figure 6 As shown, according to an embodiment of the present invention, a control device 800 for a cooking appliance is also provided. The control device 800 is used for a cooking appliance, which includes a housing and a steam exhaust assembly. The housing includes a cooking cavity, which is provided with an air inlet and a steam exhaust port. The steam exhaust assembly includes an air supply unit and a valve body. The valve body includes a first connecting end and a second connecting end. The air supply unit is connected to the first connecting end, and the second connecting end is connected to the air inlet. When the valve body is in the open state, the first connecting end and the second connecting end are connected, and the air supply unit can supply air into the cooking cavity through the valve body. When the valve body is in the closed state, the first connecting end and the second connecting end are disconnected. The control device 800 includes: an acquisition unit 802, used to acquire the cooking state of the cooking appliance; and a control unit 804, used to control the air supply unit and the valve body to open when the cooking appliance has finished cooking, so that the air supply unit supplies air into the cooking cavity through the valve body, and the cooking cavity exhausts steam through the steam exhaust port.

[0105] The present invention provides a control device 800 for a cooking appliance, which includes a housing and a steam exhaust assembly. The housing includes a cooking cavity for cooking food. The cooking cavity has an air inlet and an exhaust outlet. The steam exhaust assembly includes an air supply unit and a valve body. The first connecting end of the valve body is opposite to the air supply unit, and the second connecting end of the valve body is connected to the cooking cavity. The control device 800 includes an acquisition unit 802 and a control unit 804. The acquisition unit 802 is used to acquire the cooking status of the cooking appliance. The control unit 804 is used to control the air supply unit and the valve body to open when the cooking appliance has finished cooking, thereby connecting the first connecting end, the second connecting end, and the air inlet in sequence. The air supply unit can supply air into the cooking cavity through the valve body and the air inlet. As the pressure in the cooking cavity gradually increases, the air in the cooking cavity is quickly discharged from the exhaust outlet, realizing the steam or moisture removal of the cooking appliance, improving the steam exhaust efficiency and safety performance, and preventing the user from being scalded by hot air when opening the door. Furthermore, during steam cooking, the reduced amount of steam within the cooking chamber leads to less steam condensation after cooking, resulting in less condensation at the bottom of the chamber and reducing the hassle of cleaning accumulated water. Simultaneously, with the valve closed, the first and second connections are disconnected, preventing air from flowing through the valve to the air supply unit and avoiding damage to other components of the cooking appliance, thus ensuring the reliability of the cooking process.

[0106] Optionally, the cooking appliance includes a heating element, which includes a steam generator, enabling steam cooking of food inside the cooking cavity.

[0107] In some embodiments, optionally, the step of the control unit 804 controlling the opening of the air supply unit and the valve body when the cooking appliance has finished cooking includes: controlling the air supply unit to open based on the cooking status being that cooking is complete; and opening the valve body after the air supply unit has been running for a first period of time.

[0108] In this embodiment, when cooking is complete, the air supply unit is turned on first, and then the valve body is opened after the air supply unit has been running for a first period of time. This can prevent the steam or moisture in the cooking cavity from flowing back through the valve body, thereby ensuring the reliability of steam or moisture discharge and preventing the air supply unit from being damaged if steam or moisture flows back into the air supply unit.

[0109] Optionally, the first duration is greater than or equal to 2 seconds and less than or equal to 10 seconds.

[0110] Optionally, the first duration can be any value among 2s, 3s, 4s, 5s, 6s, 7s, 8s, 9s, and 10s.

[0111] In some embodiments, optionally, the valve body includes a valve seat, a valve core, and a drive member. The valve seat includes a first connecting end and a second connecting end. The valve core is rotatably disposed within the valve seat and is used to connect or block the first connecting end and the second connecting end. The drive member is disposed within the valve seat and connected to the valve core, and is used to drive the valve core to rotate within the valve seat. The step of the control unit 804 opening the valve body includes: controlling the drive member to work so that the drive member drives the valve core to rotate, and connecting the first connecting end and the second connecting end.

[0112] In this embodiment, the valve body includes a valve seat, a valve core, and a drive component. The valve seat has a first connecting end and a second connecting end. The valve core is movably disposed within the valve seat and can rotate within the valve seat, thereby enabling the valve body to switch between an open state and a closed state. The step of opening the valve body includes controlling the drive component to operate, causing the drive component to drive the valve core to rotate, thereby connecting the valve core with the first connecting end and the second connecting end, allowing the air supply unit to supply air into the cooking cavity through the first connecting end and the second connecting end.

[0113] In some embodiments, optionally, the valve core is provided with a trigger part, and the exhaust assembly further includes a first micro switch, the first micro switch being electrically connected to the drive member, the trigger part being disposed opposite to the first micro switch and used to trigger the first micro switch, and the control unit 804 controlling the drive member to work so that the drive member drives the valve core to rotate includes: turning on the drive member so that the valve core rotates in a first direction and drives the trigger part to rotate; and turning off the drive member when the trigger part triggers the first micro switch.

[0114] In this embodiment, a trigger part is provided on the valve core, and the exhaust assembly includes a first micro switch. The first micro switch is electrically connected to the drive member and is disposed opposite to the trigger part. The step of controlling the drive member to work so that the valve core rotates includes controlling the valve core to rotate in a first direction so that the trigger part on the valve core rotates with the valve core. When the trigger part triggers the first micro switch, the drive member stops working, so that the valve core remains in the open state.

[0115] In some embodiments, the steam venting assembly may optionally include a second micro switch, which is electrically connected to the drive member. A triggering part is disposed opposite to the second micro switch and is used to trigger the second micro switch. The control unit 804 is further configured to: determine whether the cooking cavity has completed steam venting; if the cooking cavity has completed steam venting, control the drive member to open so that the valve core rotates in a second direction and drives the triggering part to rotate; if the triggering part triggers the second micro switch, close the drive member so that the valve core blocks the first connection end and the second connection end; the first direction is opposite to the second direction.

[0116] In this embodiment, the steam venting assembly further includes a second micro switch. The second micro switch is electrically connected to the drive component and is disposed opposite to the triggering part. The control unit 804 is also used to: determine whether the cooking cavity has completed steam venting. If the cooking cavity has completed the steam venting operation, the valve body needs to be closed. At this time, the drive component is controlled to work, so that the valve core rotates in the second direction, thereby driving the triggering part to rotate in the second direction with the valve core. When the triggering part triggers the second micro switch, it indicates that the valve core has rotated to the correct position. Then the drive component is closed, the drive on the valve core is stopped, so that the valve core remains in the closed state, the first connection end and the second connection end are disconnected, and the whole machine is reset.

[0117] It is understandable that the angle by which the valve core rotates in the first direction during the opening process is the same as the angle by which the valve core rotates in the second direction during the closing process.

[0118] Specifically, along the circumferential rotation of the valve core, the triggering part is located between the first micro switch and the second micro switch. Thus, when the valve core rotates in the first direction and reaches its position, the first micro switch is triggered, and when the valve core rotates in the second direction and reaches its position, the second micro switch is triggered.

[0119] In some embodiments, optionally, the cooking appliance includes a door for opening or closing the cooking cavity. The step of the control unit 804 in determining whether the cooking cavity has completed venting includes: obtaining opening information of the door and confirming that the cooking cavity has completed venting based on the door being in an open state; or obtaining the running time of the venting component and confirming that the cooking cavity has completed venting based on the running time being greater than or equal to the target time.

[0120] In this embodiment, determining whether the cooking cavity has completed venting can be done by detecting the running time of the venting component or by observing the opening and closing status of the door. Specifically, if the door is open, confirming that the cooking cavity has completed venting prevents continued airflow into the cooking cavity from causing airflow to flow out of the door and directly hit the user's face, affecting the user experience; or, if the venting component has run for the target duration, confirming that the cooking cavity has completed venting prevents prolonged airflow from causing the food inside the cooking cavity to cool down.

[0121] Understandably, the target duration can be set according to the actual situation, such as any value between 1 minute and 20 minutes.

[0122] In some embodiments, optionally, after the step of shutting down the drive, the control unit 804 is further configured to: shut down the air supply unit while the drive has been shut down for a second duration.

[0123] In this embodiment, after confirming that the cooking cavity has completed steam venting, the air supply unit is turned off after the second time period of the drive unit is turned off, so as to ensure that the air supply unit is turned off only after the valve body is completely closed, thereby preventing the hot air in the cooking cavity from flowing to the location of the air supply unit.

[0124] like Figure 1 , Figure 2 and Figure 3 As shown, according to an embodiment of the present invention, a cooking appliance is also provided, comprising: a housing 1, the housing 1 including a cooking cavity 10, the cooking cavity 10 having an air inlet 102 and an exhaust port 104; an exhaust assembly 2, disposed outside the cooking cavity 10, the exhaust assembly 2 including an air supply unit 20 and a valve body 22, the valve body 22 including a first connecting end 220 and a second connecting end 222, the air supply unit 20 being connected to the first connecting end 220, and the second connecting end 222 being connected to the air inlet 102; the valve body 22 having an open state and a closed state, wherein when the valve body 22 is in the open state, the first connecting end 220 and the second connecting end 222 are connected, and the air supply unit 20 can supply air into the cooking cavity 10 through the valve body 22; and when the valve body 22 is in the closed state, the first connecting end 220 and the second connecting end 222 are disconnected; and a control device 800 as described in the above embodiment.

[0125] The cooking appliance provided by this invention includes a housing 1, a steam exhaust assembly 2, and a control device 800. The housing 1 includes a cooking cavity 10 for cooking food. The cooking cavity 10 is provided with an air inlet 102 and a steam exhaust port 104. The steam exhaust assembly 2 is disposed on the housing 1 outside the cooking cavity 10. The steam exhaust assembly 2 includes an air supply unit 20 and a valve body 22. The first connecting end 220 of the valve body 22 is disposed opposite to the air supply unit 20, and the second connecting end 222 of the valve body 22 is connected to the cooking cavity 10. Thus, when the valve body 22 is in the open state, the first connecting end 220, the second connecting end 222, and the air inlet 102 are connected in sequence. The air supply unit 20 can supply air into the cooking cavity 10 through the valve body 22 and the air inlet 102. As the pressure inside the cooking cavity 10 gradually increases, the air inside the cooking cavity 10 is discharged through the steam exhaust port 104, realizing the steam exhaust of the cooking cavity 10 and improving the steam exhaust efficiency and safety performance. With valve body 22 in the closed state, the first connection end 220 and the second connection end 222 are disconnected, preventing the hot and humid air in the cooking cavity 10 from flowing to the location of the air supply unit 20 via valve body 22, thus avoiding damage to other components of the cooking appliance. Simultaneously, the control device 800 can control the exhaust assembly 2 to supply air to the cooking cavity 10 after cooking is complete, based on the cooking status of the appliance. This achieves steam or moisture removal, improving exhaust efficiency and safety, and preventing scalding from hot air when the user opens the door. Furthermore, in steam cooking, the reduced amount of steam in the cooking cavity 10 leads to less steam condensation after cooking, resulting in less condensate buildup at the bottom of the cooking cavity 10 and reducing the hassle of cleaning accumulated water.

[0126] Specifically, when the valve body 22 is in the open state and the air supply unit 20 is turned on, the airflow follows... Figure 1 and Figure 2 The flow is in the direction indicated by the middle arrow.

[0127] like Figure 3 As shown, in some embodiments, the valve body 22 may optionally include: a valve seat 23, the valve seat 23 including a first connecting end 220 and a second connecting end 222; a valve core 24, rotatably disposed within the valve seat 23, for connecting the first connecting end 220 and the second connecting end 222, or for blocking the first connecting end 220 and the second connecting end 222; and a driving member 25, disposed within the valve seat 23 and connected to the valve core 24, for driving the valve core 24 to rotate within the valve seat 23.

[0128] In this embodiment, the valve body 22 includes a valve seat 23, a valve core 24, and a drive member 25. The valve seat 23 has a first connecting end 220 and a second connecting end 222. The valve core 24 is movably disposed within the valve seat 23 and can rotate within the valve seat 23. The drive member 25 can drive the valve core 24 to rotate, thereby allowing the valve body 22 to switch between an open state and a 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, and the air supply unit 20 supplies air into the cooking cavity 10 through the valve body 22 and the air inlet 102, so that the hot and humid air in the cooking cavity 10 is discharged through the steam outlet 104 of the cooking cavity 10, realizing the dehumidification or steam removal in the cooking cavity 10, thereby improving the cooking effect on the food. When the valve body 22 is in the closed state, the valve core 24 separates the first connection end 220 and the second connection end 222, thereby disconnecting the first connection end 220 and the second connection end 222. As a result, the air supply unit 20 can no longer supply air into the cooking cavity 10, and the air in the cooking cavity 10 cannot flow back to the valve body 22 and the location of the air supply unit 20 through the air inlet 102, thus ensuring the safety performance of other components.

[0129] like Figure 3 As shown, in some embodiments, optionally, the exhaust assembly 2 further includes: a first micro switch 260, disposed on the valve seat 23 and electrically connected to the drive member 25, with a trigger part 246 provided on the valve core 24, and the first micro switch 260 located on one side of the trigger part 246 along a first direction; a second micro switch 262, disposed on the valve seat 23 and electrically connected to the drive member 25, with a trigger part 246 provided on the valve core 24, and the second micro switch 262 located on one side of the trigger part 246 along a second direction; when the trigger part 246 triggers the first micro switch 260, the drive member 25 is closed and the valve body 22 is in an open state; when the trigger part 246 triggers the second micro switch 262, the drive member 25 is closed and the valve body 22 is in a closed state.

[0130] In this embodiment, the exhaust assembly 2 further includes a first micro switch 260 and a second micro switch 262. A triggering part 246 is provided on the valve core 24, which is disposed opposite to the first micro switch 260 and the second micro switch 262, and is used to trigger the first micro switch 260 and the second micro switch 262. Specifically, when the driving member 25 drives the valve core 24 to rotate in a first direction, the triggering part 246 moves with the valve core 24. When the triggering part 246 triggers the first micro switch 260, a signal is fed back to the driving member 25, causing the driving member 25 to stop moving and controlling 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 driving member 25 drives the valve core 24 to rotate in a second direction, the triggering part 246 moves with the valve core 24. When the triggering part 246 triggers the second micro switch 262, a signal is fed back to the driving member 25, causing the driving 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.

[0131] Optionally, one of the first direction and the second direction is the forward rotation direction of the motor shaft, and the other is the reverse rotation direction.

[0132] Specifically, the first direction is the forward rotation of the motor shaft, and the second direction is the reverse rotation.

[0133] like Figure 3 As shown, in some embodiments, optionally, the valve core 24 includes: a rotating drum portion 240 rotatably connected to the valve seat 23, the rotating drum portion 240 having a channel 242 extending radially through the rotating drum portion 240, and a driving member 25 connected to the rotating drum portion 240 for driving the rotating drum portion 240 to rotate around the axis of the rotating drum portion 240, so that the valve body 22 switches between an open state and a closed state; when the valve body 22 is in the open state, the two ends of the channel 242 are connected to the first connecting end 220 and the second connecting end 222; when the valve body 22 is in the closed state, the wall of the rotating drum portion 240 blocks the first connecting end 220 and the second connecting end 222.

[0134] In this embodiment, the valve core 24 includes a rotating drum portion 240, on which a channel 242 is provided that passes through the rotating drum portion 240 radially. The driving member 25 is connected to 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 to achieve the switching between the open state and the closed state of the valve body 22. Specifically, when 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 connected through the channel 242, and the air supply unit 20 can supply air into the cooking cavity 10 through the valve body 22; when the valve body 22 is in the closed state, the wall 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, preventing the air in the cooking cavity 10 from flowing to the chamber where the air supply unit 20 is located.

[0135] Optionally, such as Figure 3 As shown, A is the axis of the rotating drum 240, and B is the radial direction of the rotating drum 240.

[0136] like Figure 3 As shown, in some embodiments, the valve core 24 may optionally include a connecting portion 244, a part of which is located inside the valve seat 23 and connected to the rotating drum portion 240, and another part of which extends to the outside of the valve seat 23 and is connected to the driving member 25. The driving member 25 drives the rotating drum portion 240 to rotate through the connecting portion 244, and a trigger portion 246 is provided at one end of the connecting portion 244 located outside the valve seat 23.

[0137] In this embodiment, the valve core 24 further includes a connecting portion 244, which is connected to the drive member 25 and the rotating drum portion 240, thereby realizing the transmission of power. Simultaneously, by extending the connecting portion 244 out of the valve seat 23, the length of the output shaft on the drive member 25 is shortened, which helps to reduce costs. A trigger portion 246 is located at the end of the connecting portion 244 located outside the valve seat 23 to trigger the first microswitch 260 and the second microswitch 262.

[0138] Optionally, the trigger part 246 is cam-shaped.

[0139] like Figure 3 As shown, in some embodiments, the valve seat 23 may optionally include: a seat body 230; a cover body 232, which is disposed opposite to and connected to the seat body 230 along the axis of the rotating cylinder portion 240, the rotating cylinder portion 240 being located between the base and the cover body 232, and the seat body 230 and the cover body 232 enclosing a first connecting end 220 and a second connecting end 222.

[0140] In this embodiment, the valve seat 23 includes a seat body 230 and a cover body 232. The seat body 230 and the cover body 232 are connected to enclose a space for installing the valve core 24, which facilitates the installation of the valve core 24. At the same time, the seat body 230 and the cover body 232 enclose a first connecting end 220 and a second connecting end 222, which realizes communication with the air supply unit 20 and the air inlet 102.

[0141] like Figure 3 As shown, in some embodiments, the exhaust assembly 2 may optionally include an air guide pipe 27, and the second connection end 222 is connected to the air inlet 102 through the air guide pipe 27.

[0142] In this embodiment, the exhaust assembly 2 further includes an air guide pipe 27, which connects the second connection end 222 and the air inlet 102, so that the second connection end 222 is connected to the air inlet 102 through the air guide pipe 27, thereby improving the diversity of the valve body 22's installation position.

[0143] In some embodiments, the air duct 27 may optionally include a silicone tube or a rubber tube.

[0144] In this embodiment, the air guide tube 27 includes a silicone tube or a rubber tube, which makes the air guide tube 27 flexible, thereby improving the sealing performance at the connection between the air guide tube 27 and the second connecting end 222 and the air inlet 102, and preventing air leakage.

[0145] like Figure 1 As shown, in some embodiments, the cooking appliance may optionally include: an electrical component 3, the housing 1 may also include a mounting cavity 12, the mounting cavity 12 is located on one side of the cooking cavity 10, the exhaust assembly 2 is disposed in the mounting cavity 12, the electrical component 3 is disposed in the mounting cavity 12; and a cooling fan 4 is disposed in the mounting cavity 12 for cooling the electrical component 3.

[0146] In this embodiment, the cooking appliance also includes an electrical component 3 and a cooling fan 4. The exhaust assembly 2, the cooling fan 4, and the electrical component 3 are all disposed in the mounting cavity 12. The cooling fan 4 is used to send air to the electrical component 3 to dissipate heat from the electrical component 3 in the mounting cavity 12 and improve the working performance of the electrical component 3. By disposing of the exhaust assembly 2 in the mounting cavity 12, the space occupied by the exhaust assembly 2 in the cooking appliance is reduced.

[0147] In some embodiments, the cooking appliance may optionally include a door, the cooking cavity 10 may also include a cooking opening 106, the door is used to open or close the cooking opening 106, and the vent 104 is located on the same side of the cooking cavity 10 as the cooking opening 106.

[0148] In this embodiment, the vent 104 and the cooking opening 106 are located on the same side of the cooking cavity 10, thereby avoiding the vent 104 being blocked and ensuring the reliability of the dehumidification operation.

[0149] In some embodiments, optionally, the vent 104 is located at the top of the cooking opening 106; and / or the vent 104 is disposed near at least one of the opposite side walls of the cooking cavity 10.

[0158] According to one embodiment of the present invention, a readable storage medium is also provided, on which a program or instructions are stored. When the program or instructions are executed, the steps of the control method for the cooking appliance as described in any of the above claims are implemented, and thus have all the beneficial effects of the control method for the cooking appliance, which will not be elaborated here.

[0159] In practical applications, the exhaust assembly 2 is mounted on the air guide plate and connected to the cooking cavity 10 via a silicone tube. Dry airflow from the outside is injected through the exhaust assembly 2, forcibly expelling moisture from the cooking cavity 10 through the exhaust port 104, thus achieving airflow exchange and expelling moisture from the cooking cavity 10. The air inlet 102 can be located at the upper left, upper right, side, top, or bottom of the cooking cavity 10. The exhaust port 104 can be located at the upper left or upper right of the cooking cavity 10.

[0160] Specifically, the exhaust assembly 2 includes a base 230, a cover 232, a rotating drum 240, a DC fan (e.g., an air supply unit 20), an AC motor, a micro switch, and an air duct 27. The rotating drum 240 has a butterfly-shaped vent (e.g., channel 242) and is connected to the base 230 and cover 232, allowing it to rotate 360°. The rotating drum 240 has a cam structure (e.g., trigger part 246) that triggers the micro switch, thereby fixing and switching the posture of the rotating drum 240. A connecting rod structure (e.g., connecting part 244) on the rotating drum 240 is connected to the AC motor, which drives the rotating drum 240 to rotate via a contoured shaft. The air duct 27 is connected to the base 230, and the DC fan serves as the air intake source, blowing air into the cooking cavity 10.

[0161] The entire steam exhaust assembly operates as follows: After the user finishes steam cooking, the program controls the on / off valve to operate. The rotating drum 240 is driven to rotate by an AC motor. When the channel 242 of the rotating drum 240 rotates 90° and connects with the silicon air guide pipe 27, the first micro switch 260 is triggered to stop. At this time, the DC fan is directly connected to the cooking cavity 10 through the air guide pipe 27. The DC fan generates airflow that blows into the cooking cavity 10. As airflow is continuously injected into the cooking cavity 10, the air pressure inside the cooking cavity 10 increases, thereby forcibly expelling the steam from the exhaust port 104. This reduces the amount of steam in the cooking cavity 10, so that when the user opens the door, they can hardly feel any steam, fundamentally eliminating the risk of steam hitting their face and causing steam burns. Because the amount of steam in the cooking cavity 10 is reduced, the amount of steam condensation caused by the temperature drop after cooking is reduced, which in turn reduces the amount of condensate water accumulating at the bottom of the cooking cavity 10, thus alleviating the user's hassle of cleaning accumulated water.

[0162] When the user opens the door or after a specific steam release time, the AC motor starts, driving the rotating drum 240 to rotate 90°. At this time, the second micro switch 262 is triggered, and the AC motor stops. The channel 242 of the rotating drum 240 is now orthogonal to the air duct 27, thus blocking the airflow between the cooking cavity 10 and the DC fan. The DC fan stops working, the steam release function is turned off, and the entire unit resets.
