[0018] When the heating assembly is operating, the heating assembly can heat the food by heat radiation, and when the adjustable speed driving element drives the impeller to rotate, the impeller blows the gas to form a circulating airflow in the cooking cavity, so that the food can also be heated by heat convection. One important factor affecting the heat convection efficiency is the flow rate of the fluid.

[0033] Fourthly, this application proposes a control device for a cooking apparatus, including a memory and a processor.

[0034] Fifthly, this application proposes a readable storage medium having a program or instructions stored thereon, wherein when the program or instructions are executed by a processor, they implement the steps of the control method for the cooking apparatus as described in the second aspect.

[0035] Sixthly, this application proposes a cooking device, comprising: a housing, the housing including a cooking cavity, the cooking cavity having an air inlet and an exhaust outlet; a dehumidification assembly disposed outside the cooking cavity, the dehumidification 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 being connected to the first connecting end, and the second connecting end being connected to 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.

[0036] The cooking equipment provided in this application includes a housing and a dehumidification assembly. The housing includes a cooking cavity for cooking food. The cooking cavity has an air inlet and an air outlet, and the dehumidification assembly is located on the housing outside the cooking cavity. The dehumidification 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. When the valve body is open, the first connecting end, the second connecting end, and the air inlet are sequentially connected, allowing the air supply unit to 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 air outlet, achieving dehumidification of the cooking cavity and improving dehumidification efficiency and safety performance. When the valve body is closed, the first connecting end and the second connecting end are disconnected, preventing the hot and humid air inside the cooking cavity from flowing to the location of the air supply unit through the valve body, thus avoiding damage to other components of the cooking equipment.

[0037] In some technical solutions, the valve body may optionally include: a valve seat, the valve seat including a first connecting end and a second connecting end; and a valve core, rotatably disposed within the valve seat, for connecting the first connecting end and the second connecting end, or for blocking the first connecting end and the second connecting end.

[0038] In this technical solution, the valve body includes a valve seat and a valve core. 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 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 and second connecting ends, 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 exhaust port of the cooking cavity, achieving dehumidification and improving the cooking effect on the food. When the valve body is in the closed state, the valve core separates the first and second connecting ends, disconnecting the connection between them. This prevents the air supply unit from supplying air into the cooking cavity, and the air in the cooking cavity cannot flow back into the valve body and the air supply unit through the air inlet, thus ensuring the safety performance of other components.

[0039] In some technical solutions, the valve body may optionally include a driving element, which is disposed on the valve seat and connected to the valve core, for driving the valve core to rotate within the valve seat.

[0040] In this technical solution, the valve body also includes a driving component, which is disposed on the valve seat and connected to the valve core to drive the valve core to rotate within the valve seat, thereby realizing automated control of the valve core's movement.

[0042] In this technical solution, the valve core includes a rotating cylinder with a radially penetrating channel. A driving component 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 and preventing air from flowing into the chamber where the air supply unit is located.

[0043] In some technical solutions, the valve core may optionally include a connecting part, a portion of which is located inside the valve seat and connected to the rotating drum part, and another portion of which extends to the outside of the valve seat and is connected to the driving member, which drives the rotating drum part to rotate through the connecting part.

[0044] In this technical solution, the valve core also includes a connecting part, which connects to the drive component and the rotating drum, thereby realizing the transmission of power. At the same time, by extending the connecting part out of the valve seat, the length of the output shaft on the drive component is shortened, which helps to reduce costs.

[0045] In some technical solutions, the dehumidification assembly may optionally include: at least two microswitches, disposed on the valve seat and electrically connected to the drive component, with a trigger part provided on the connection part, the trigger part being located outside the valve seat. When the valve body is in the open state, the trigger part triggers at least one microswitch, and when the valve body is in the closed state, the trigger part triggers another microswitch.

[0046] In this technical solution, the dehumidification assembly further includes at least two microswitches. A trigger part is provided on the connecting part, and the trigger part is arranged opposite to the at least two microswitches to realize the triggering of the at least two microswitches. Specifically, when the driving member drives the rotating drum to move through the connecting part, the trigger part moves with the connecting part. When the valve body is in the open state, the trigger part triggers at least one microswitch and feeds back to the driving member, so that the driving member controls the rotating drum to remain in the state of conducting the first connecting end and the second connecting end; when the valve body is in the closed state, the trigger part triggers another microswitch and feeds back to the driving member, so that the driving member controls the rotating drum to remain in the state of blocking the first connecting end and the second connecting end.

[0047] In some technical solutions, the valve seat may optionally include: a seat body; a cover body, which is disposed opposite to and connected to the seat body along the axis of the rotating cylinder, the rotating cylinder being located between the base and the cover body, and the seat body and the cover body enclosing a first connecting end and a second connecting end.

[0048] In this technical solution, the valve seat includes a seat body and a cover body. The seat body and the cover body are connected to enclose a space for installing the valve core, which facilitates the installation of the valve core. At the same time, the seat body and the cover body enclose a first connecting end and a second connecting end, realizing communication with the air supply unit and the air inlet.

[0049] In some technical solutions, the dehumidification component may optionally include an air duct, with the second connection end connected to the air inlet via the air duct.

[0050] In this technical solution, the dehumidification component also includes an air guide pipe, which connects the second connection end and the air inlet, so that the second connection end is connected to the air inlet through the air guide pipe, thereby improving the versatility of valve body setting positions.

[0051] In some technical solutions, the air delivery tube may optionally include a silicone tube or a rubber tube.

[0052] In this technical solution, the air guide tube includes a silicone tube or a rubber tube, which gives the air guide tube a certain degree of flexibility, thereby improving the sealing performance of the connection between the air guide tube and the second connecting end and the air inlet, and preventing air leakage.

[0053] In some technical solutions, the housing may optionally include: a mounting cavity located on one side of the cooking cavity, with a dehumidification component disposed within the mounting cavity.

[0054] In this technical solution, the dehumidification component is installed inside the installation cavity to protect it.

[0056] In this technical solution, the cooking equipment also includes electrical components and a cooling fan. Both the cooling fan and the electrical components are installed inside the mounting cavity. The cooling fan is used to blow air to the electrical components to dissipate heat from the electrical components inside the mounting cavity and improve the working performance of the electrical components.

Detailed Implementation

[0083] To better understand the above-mentioned objectives, features, and advantages of this application, the application 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.

[0084] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below.

[0085] The following describes, with reference to Figures 1 to 11, some embodiments of a cooking apparatus, a method for controlling a cooking apparatus, a control device for a cooking apparatus, and a readable storage medium provided according to this application.

[0086] As shown in Figure 1, an embodiment of this application proposes a cooking device, including: a housing 100, a heating assembly 200, an adjustable speed drive 300, and an impeller 400. The housing 100 has a cooking cavity 110. The heating assembly 200 and the adjustable speed drive 300 are connected to the housing 100 and are used to heat the inside of the cooking cavity 110. The rotational speed of the adjustable speed drive 300 is associated with target cooking parameters. The impeller 400 is connected to the adjustable speed drive 300, which drives the impeller 400 to rotate. The impeller 400 drives the airflow within the cooking cavity 110.

[0087] The housing 100 is provided with a cooking cavity 110, which is used to place the food to be cooked. A heating element 200 is installed on the inner wall of the cooking cavity 110, which is used to heat the food in the cooking cavity 110. An adjustable speed drive 300 is installed on the housing 100, and an impeller 400 is connected to the adjustable speed drive 300. The adjustable speed drive 300 is used to drive the impeller 400 to rotate, and the speed of the adjustable speed drive 300 can be adjusted, thereby realizing the speed regulation of the impeller 400.

[0088] When the heating component 200 is running, it heats the food through thermal radiation. With the adjustable speed drive 300 driving the impeller 400 to rotate, the impeller 400 blows gas, creating a circulating airflow within the cooking cavity 110, thus also heating the food through thermal convection. A key factor affecting the efficiency of heat transfer through convection is the fluid velocity. By controlling the airflow speed within the cooking cavity 110 during baking, the efficiency of heat transfer through convection can be controlled. When cooking the same food at the same temperature and time, a higher airflow speed results in a higher convective heat transfer coefficient, faster heat transfer and moisture evaporation from the food surface, and greater crispness and browning at the end of cooking. Utilizing this principle, a fan control module can be added to steam-baked and microwave-steam-baked products. This means that the output speed of the adjustable speed drive 300 can be adjusted. On one hand, different airflow speeds can be used to adjust the crispness and browning of the food; on the other hand, different airflow speeds can be controlled at different stages of cooking to achieve better cooking results and better meet the user's cooking needs.

[0089] Before cooking, target cooking parameters are obtained, including a target rotation speed. Based on the target rotation speed, the adjustable rotation speed drive 300 is controlled to operate. This cooking product, which allows control of the airflow speed within the cooking cavity 110, can adjust the speed of hot air flow within the cooking cavity 110 according to the cooking needs of different foods through the air control module, thereby achieving airflow control during the cooking process and achieving better cooking results. For example, the cooking equipment can be an oven, a steam oven, or a microwave-steam-oven combination appliance.

[0090] For example, the cooking device in this embodiment can be a household oven, a household steam oven, or a household microwave steam oven. During the baking process, the airflow speed inside the cavity can be adjusted via the air control module. Different air speeds can be controlled at different stages of the cooking process according to the cooking requirements of different foods to achieve the best cooking effect. Alternatively, different air speeds can be used to cook foods to achieve different levels of crispness and browning based on the user's desired crispness or browning.

[0091] In one possible application, the cooking device also includes a control module 600, which controls the rotational speed of the adjustable speed drive 300. The higher the rotational speed of the adjustable speed drive 300, the faster the impeller 400 rotates, and the greater the airflow speed entering the cooking chamber 110. Three fan speeds (low, medium, and high) are defined based on the actual cooking effect of different speeds. The low speed corresponds to a lower rotational speed of the adjustable speed drive 300 and a lower airflow speed, resulting in lower convective heat transfer efficiency during cooking. Conversely, the high speed corresponds to a higher rotational speed of the adjustable speed drive 300 and a higher airflow speed, resulting in higher convective heat transfer efficiency during cooking. When the same food is cooked at the same temperature for the same amount of time, different fan speeds can produce significantly different results in terms of crispness and color. Specifically, at the low fan speed, the color is lighter and the surface dehydration is less (less crispness); at the medium fan speed, the color is moderate and the surface dehydration is moderate (moderate crispness); and at the high fan speed, the color is darker and the surface dehydration is greater (greater crispness). Of course, in other embodiments, the three speeds are not limited to those mentioned above.

[0092] In some embodiments, the adjustable speed drive 300 may optionally include any of the following: a DC motor, a shaded pole motor, a variable frequency motor, a servo motor, and a stepper motor.

[0093] When a DC motor is used as the driving component of the impeller 400, the controller in the cooking equipment can adjust the duty cycle of PWM (Pulse Width Modulation) through analog signals to achieve stepless speed regulation of the DC motor.

[0094] When the shaded-pole motor is used as the driving component of the impeller 400, the shaded-pole motor achieves different output speeds through different coil positions.

[0095] When the variable frequency motor is used as the driving component of the impeller 400, the variable frequency motor uses a frequency converter to control the power supply frequency and voltage, thereby achieving different output speeds of the variable frequency motor.

[0096] When the servo motor is used as the driving component of the impeller 400, the servo motor uses a feedback control system, which typically uses an encoder or other sensors to detect the motor's speed and position, and performs speed control according to the set values.

[0097] When the stepper motor is used as the driving component of the impeller 400, the stepper motor rotates in fixed steps by applying pulse signals through the control power supply, and the speed is adjusted by adjusting the pulse frequency and direction.

[0098] As shown in Figure 1, in some embodiments, the cooking device may optionally include: a cover plate 500, which is connected to the inner wall of the cooking cavity 110, and an impeller 400 located between the cover plate 500 and the inner wall of the cooking cavity 110. The cover plate 500 is provided with a first air inlet 511 and a first air outlet 520, both of which are connected to the cooking cavity 110.

[0099] A cover plate 500 is installed on the inner wall of the cooking cavity 110. The cover plate 500 covers the impeller 400 and protects the impeller 400, preventing the food in the cooking cavity 110 from contacting the impeller 400 and reducing the damage rate of the impeller 400.

[0100] A first air inlet 511 and a first air outlet 520 are provided on the cover plate 500. When the impeller 400 rotates, the gas in the cooking chamber 110 can be drawn into the space between the cover plate 500 and the inner wall of the chamber through the first air inlet 511. Under the blowing of the impeller 400, the gas between the cover plate 500 and the inner wall of the chamber is blown into the cooking chamber 110 through the first air outlet 520, thereby forming a circulating airflow in the cooking chamber 110.

[0101] In one possible application, the first air inlet 511 is located circumferentially to the first air outlet 520, or the first air outlet 520 is located circumferentially to the first air inlet 511. That is, the impeller 400 can drive the airflow by means of central air intake or circumferential air intake.

[0102] As shown in Figure 2, in some embodiments, optionally, the impeller 400 is located outside the cooking chamber 110, and the chamber wall of the cooking chamber 110 is provided with a second air inlet 530 and a second air outlet 540. The impeller 400 blows airflow into the cooking chamber 110 through the second air inlet 530 and the second air outlet 540. As shown in Figure 2, a second air inlet 530 and a second air outlet 540 are provided on one of the cooking chamber walls 111 of the cooking chamber 110.

[0103] The impeller 400 can be placed outside the cooking cavity 110. The impeller 400 will not occupy the space inside the cooking cavity, thus providing more space for placing ingredients inside the cooking cavity 110. The impeller 400 blows air into the cooking cavity 110 through the second air inlet 530. The air in the cooking cavity 110 can be drawn out by the impeller 400 through the second air outlet 540, thus forming a circulating airflow inside the cooking cavity 110.

[0104] As shown in Figure 1, in some embodiments, optionally, the heating assembly 200 includes a first heating element 210, and the first heating element 210 and the cover plate 500 are disposed on the same inner wall of the cooking cavity 110.

[0105] The first heating element 210 is installed on the inner wall of the cooking cavity 110 and is used to heat the food. The cover plate 500 and the first heating element 210 are installed on the same inner wall of the cavity, so the first heating element 210 can be set close to the impeller 400. When the impeller 400 rotates, the airflow near the impeller 400 is faster. When the high-speed airflow passes through the first heating element 210, the airflow can quickly carry away the heat on the surface of the first heating element 210. When the heated airflow passes through the food, it can quickly heat the food, which helps to improve the heating efficiency of the food.

[0106] If the adjustable speed drive 300, impeller 400 and cover plate 500 are located at the top of the cooking chamber 110, the heat from the first heating element 210 heats the high-speed airflow. If the adjustable speed drive 300, impeller 400 and cover plate 500 are located on the sides of the cooking chamber 110 where there are no heating components 200, then the impeller 400 disturbs the gas heated by the heating components 200 inside the cooking chamber 110.

[0107] As shown in Figure 1, in some embodiments, the first heating element 210 is optionally located between the cover plate 500 and the inner wall of the cooking cavity 110.

[0108] With the impeller 400 positioned between the cover plate 500 and the inner wall of the cooking cavity 110, and the first heating element 210 also positioned between the cover plate 500 and the inner wall of the cooking cavity 110, the close proximity of the first heating element 210 to the impeller 400 further increases the speed at which the airflow carries heat to the surface of the first heating element 210, thereby increasing the heating speed of the food. Furthermore, by positioning the first heating element 210 between the cover plate 500 and the inner wall of the cooking cavity 110, the cover plate 500 provides protection for the first heating element 210, preventing direct contact between the food and the first heating element 210, thus preventing the food from burning due to contact with the first heating element 210.

[0109] For example, the first heating element 210 is located between the cover plate 500 and the top wall of the cavity, or the first heating element 210 is located between the cover plate 500 and the side wall of the cavity.

[0110] As shown in Figure 1, in some embodiments, the heating assembly 200 may optionally include a second heating element 220, wherein the first heating element 210 and the second heating element 220 are disposed on different inner walls of the cooking cavity 110.

[0111] Both the first heating element 210 and the second heating element 220 are used to heat the food. Since the first heating element 210 and the second heating element 220 are arranged on different inner walls of the cavity, the first heating element 210 and the second heating element 220 can heat the food from different directions, which is beneficial to improving the uniformity of heating the food.

[0112] As shown in Figure 1, in some embodiments, the heating assembly 200 may optionally include: a third heating element 230, the cooking cavity 110 having an opening 120, a first heating element 210 disposed on the inner wall of the cooking cavity 110 opposite to the opening 120, a second heating element 220 disposed on the top wall of the cooking cavity 110, and a third heating element 230 disposed on the bottom wall of the cooking cavity 110.

[0113] The first heating element 210, the second heating element 220, and the third heating element 230 can heat the food together, or the first heating element 210, the second heating element 220, and the third heating element 230 can heat the food in different combinations, which is conducive to improving the diversity of cooking modes. In different cooking scenarios, different heating combinations are conducive to improving the cooking effect of the food.

[0114] In an embodiment of this application, a control method for a cooking device is proposed, wherein the cooking device includes: a housing, a heating component, an adjustable speed drive, and an impeller. The housing has a cooking cavity, the heating component is connected to the housing and is used to heat the inside of the cooking cavity, the adjustable speed drive is connected to the housing, and the impeller is connected to the adjustable speed drive. The adjustable speed drive is used to drive the impeller to rotate, and the impeller is used to drive the airflow inside the cooking cavity.

[0115] As shown in Figure 3, the control methods for cooking equipment include:

[0116] Step 202: Obtain the target cooking parameters, which include the target rotation speed of the adjustable rotation speed drive.

[0117] Step 204: Control the operation of the adjustable speed drive according to the target speed.

[0118] When the heating element is running, it heats the food through thermal radiation. With the adjustable speed drive rotating the impeller, the impeller blows gas, creating a circulating airflow within the cooking cavity, which in turn heats the food through thermal convection. A key factor affecting the efficiency of heat transfer through convection is the fluid velocity. By controlling the airflow speed within the cooking cavity during baking, the efficiency of heat transfer through convection can be controlled. When cooking the same food at the same temperature and time, a higher airflow speed results in a higher convective heat transfer coefficient, faster heat transfer and moisture evaporation from the food surface, and greater crispness and browning at the end of cooking. Utilizing this principle, a fan control module can be added to steam-baked and microwave-steam-baked products. This means that the output speed of the adjustable speed drive can be adjusted. On one hand, different airflow speeds can be used to adjust the crispness and browning of the food; on the other hand, different airflow speeds can be controlled at different stages of cooking to achieve better cooking results and better meet the user's cooking needs.

[0119] Before cooking, the target cooking parameters are obtained, including the target rotation speed. Based on the target rotation speed, the adjustable rotation speed drive is controlled to operate. The steam oven and microwave oven proposed in this application, which can control the airflow speed inside the cooking cavity, can adjust the speed of hot air flow inside the cooking cavity through the air control module according to the cooking needs of different foods, thereby achieving airflow control during the cooking process and achieving better cooking results.

[0120] The cooking program of the control system can be stored in the control system's memory or in the cloud.

[0121] In some embodiments, optionally, before the step of obtaining the target cooking parameters, the control method of the cooking device further includes: receiving user input; determining a target cooking mode based on the user input; and determining target cooking parameters based on the target cooking mode, wherein the target cooking parameters are associated with the target cooking mode.

[0122] Users can choose cooking modes according to their needs. For example, the cooking equipment has a menu. Users can select from the menu, and each menu has corresponding target cooking parameters. The cooking equipment determines the target cooking parameters based on the user's selection, thereby realizing the cooking of the ingredients.

[0123] An automatic menu cooking program is an optimal cooking program designed for a specific recipe and portion size. The program is pre-stored in the control system's storage device, containing information such as the function mode, baking temperature, time, and fan speed setting for each stage of the cooking process. Different foods require different fan speeds at different stages of cooking; by controlling the fan speed at each stage of the cooking process through the automatic menu cooking program, optimal cooking results can be achieved. After the user selects an automatic menu and starts cooking, the control system will control the temperature and fan speed according to the signals output by the menu cooking program.

[0124] In some embodiments, optionally, before the step of obtaining the target cooking parameters, the control method of the cooking device further includes: receiving user input; determining the target cooking effect of the ingredients based on the user input, the target cooking effect including target crispness and / or target coloring; and determining the target cooking parameters based on the target cooking effect, the target cooking parameters being associated with the target cooking effect.

[0125] Users can select the crispness and color of the ingredients according to their needs. The cooking equipment has a pre-stored correspondence between crispness and color and target cooking parameters. After the user selects the crispness and color, the cooking equipment retrieves the corresponding target cooking parameters to cook the ingredients.

[0126] Before cooking, the target cooking parameters are obtained, including the target rotation speed. Based on the target rotation speed, the adjustable rotation speed drive is controlled. The steam-bake and microwave-steam oven product proposed in this application, which can control the air speed inside the cooking cavity, can adjust the speed of the hot air flow inside the cavity according to the cooking needs of different foods or according to the user's selection of browning and crispness. This achieves air speed control during the cooking process, resulting in better cooking effects. While achieving multiple levels of crispness and browning adjustment, it also makes crispy meat, air-fried foods, and other foods crispier and better in taste.

[0127] During food cooking, the airflow speed within the cooking system is closely related to the heat exchange efficiency of the food surface. High airflow speed can effectively accelerate heat absorption and moisture evaporation from the food surface. For the same food cooked at the same temperature for the same amount of time, different airflow speeds can achieve different cooking results. Low airflow speed results in lighter browning and less surface dehydration (less crispness); medium airflow speed results in moderate browning and moderate surface dehydration (moderate crispness); and high airflow speed results in darker browning and more surface dehydration (greater crispness). Through experiments, we have summarized the cooking temperature and time for various foods at different quantities. When users need to bake a certain type of food, they only need to select the corresponding food category and quantity, and choose the desired final cooking effect (crispness / browning). After starting cooking, the airflow control system will control the temperature and airflow speed according to the signals output by the corresponding program.

[0128] In some embodiments, the cooking parameters may optionally include a target cooking temperature and a target cooking time; the control method of the cooking device may further include controlling the operation of the heating component according to the target cooking temperature and the target cooking time.

[0129] Users can select any cooking mode with an impeller (such as back tube + impeller, top tube + impeller, top and bottom tubes + impeller, etc.) and set the temperature, time, and fan speed to achieve the desired cooking effect.

[0130] In some embodiments, the heating assembly may optionally include a first heating element, a second heating element, and a third heating element. The cooking cavity has an opening, the first heating element is disposed on the inner wall of the cooking cavity opposite to the opening, the second heating element is disposed on the top wall of the cooking cavity, and the third heating element is disposed on the bottom wall of the cooking cavity.

[0131] The target cooking parameters also include a target cooking temperature. After obtaining the target cooking parameters, the control method further includes controlling the operation of at least one of the first heating element, the second heating element, and the third heating element according to the target cooking temperature.

[0132] The first heating element, the second heating element, and the third heating element can heat the food together, or they can heat the food in different combinations. This is beneficial for increasing the diversity of cooking modes. In different cooking scenarios, different heating combinations are beneficial for improving the cooking effect on the food.

[0133] Given a target cooking temperature, heating can be achieved using a single heating element, a combination of two heating elements, or all three heating elements operating simultaneously. For example, at a lower target cooking temperature, one or two heating elements are sufficient, while at a higher target cooking temperature, three heating elements operating simultaneously can quickly meet the heating requirements.

[0134] In one possible application, the first heating method involves a single heating element combined with a wind control scheme, including at least one element capable of baking the cooking cavity, for example, using a heating element on the back to achieve inner cavity baking.

[0135] The second heating method is a dual-heating element superposition air control scheme, in which the first heating element works in combination with a heating element at any position on the inner cavity, or the upper and lower heating elements work in combination.

[0136] The third heating method is a three-heating-element scheme, where the first heating element, the second heating element, and the third heating element on the back work together.

[0137] In some embodiments, the target cooking parameter may optionally include a target cooking temperature. The control method for the cooking device further includes: acquiring the temperature inside the cooking cavity while the heating element is operating; maintaining or increasing the heating power of the heating element if the temperature inside the cooking cavity is lower than the target cooking temperature; and reducing the heating power of the heating element if the temperature inside the cooking cavity is higher than the target cooking temperature.

[0138] With a target cooking temperature determined, the temperature inside the cooking cavity needs to be continuously monitored during the cooking process. If the temperature inside the cooking cavity hasn't reached the target temperature during the heating phase, the heating power of the heating element can be maintained to keep the temperature rising. If the heating phase has passed and the temperature inside the cooking cavity still hasn't reached the target temperature, the heating power of the heating element needs to be increased to bring the temperature to the target temperature. If the temperature inside the cooking cavity is higher than the target cooking temperature, it indicates that the heating power of the heating element is too high; in this case, the heating power can be reduced to prevent the temperature inside the cooking cavity from becoming too high. By using this method, the temperature inside the cooking cavity can be maintained near the target cooking temperature, which is beneficial for improving the cooking effect on the food.

[0139] In some embodiments, the target cooking parameters may optionally include a target cooking temperature. After obtaining the target cooking parameters, the control method for the cooking device further includes: obtaining target rotation speed and target cooking temperature for multiple cooking stages, based on the assumption that the cooking process has multiple cooking stages; controlling the operation of an adjustable rotation speed drive according to the target rotation speed; and controlling the operation of a heating component according to the target cooking temperature.

[0140] When a cooking process has multiple stages, the target rotation speed and target cooking temperature may differ for each stage. The adjustable rotation speed drive and heating element can be controlled according to the target rotation speed and target cooking temperature for each stage. Different cooking stages allow for targeted adjustments to the target rotation speed and target cooking temperature for different ingredients, which helps improve the crispness and browning of the ingredients, thus enhancing the overall cooking effect.

[0141] As shown in Figure 4, in one possible embodiment, the control method for the cooking device includes:

[0142] Step 502: The user selects the automatic menu and starts cooking;

[0143] Step 504: The control system performs temperature control and fan speed control based on the signals output by the menu cooking program;

[0144] Step 506: The temperature sensor detects the actual temperature;

[0145] Step 508: Determine the difference between the actual temperature and the target cooking temperature;

[0146] Step 510: Start the heating component to heat up and control the temperature according to the on / off logic;

[0147] Step 512: Based on the fan speed information for different cooking time periods stored in the cooking program, output different signals at different time periods to control the speed of the adjustable speed drive.

[0148] Step 514: The adjustable speed drive drives the impeller to rotate, generating a cooking hot airflow with a corresponding wind speed in the cooking chamber.

[0149] Step 516, cooking complete.

[0150] As shown in Figure 5, in one possible embodiment, the control method for the cooking device includes:

[0151] Step 602: The user enters the baking function, selects the food and quantity, and chooses the desired crispness and browning, then starts cooking;

[0152] Step 604: The control system controls the cooking temperature and time according to the cooking program of the food in the corresponding quantity, and controls the wind speed according to the crispness and coloring selected by the user.

[0153] Step 606: The temperature sensor detects the actual temperature;

[0154] Step 608: Determine the difference between the actual temperature and the target cooking temperature;

[0155] Step 610: Start the heating component to heat up and control the temperature according to the on / off logic;

[0156] Step 612: Low crispness / light coloring, output low wind speed signal; medium crispness / medium coloring, output medium wind speed signal; high crispness / dark coloring, output high wind speed signal.

[0157] Step 614: The adjustable speed drive drives the impeller to rotate, generating a cooking hot airflow with a corresponding wind speed in the cooking chamber.

[0158] Step 616, cooking complete.

[0159] In one possible application, the cooking effect can be improved by controlling the wind speed at different stages of the crispy roast pork cooking process.

[0160] Taking the automatic menu for crispy roast pork as an example, we compare the cooking effects with and without airflow control.

[0161] 1. No fan control cooking program:

[0162] First, upper and lower heating elements + impeller (impeller fixed speed), 140℃, 1h;

[0163] Second, upper and lower heating elements + impeller (impeller fixed speed), 230℃, 20min.

[0164] 2. Features a controlled-air cooking program:

[0165] First, with upper and lower heating elements and low fan speed, 140℃, 1 hour;

[0166] Second, upper and lower heating elements + high wind speed, 230℃, 20min.

[0167] As shown in Table 1, the cooking process of crispy roast pork can be divided into a preliminary medium-temperature steaming and roasting stage and a subsequent high-temperature grilling stage. In the preliminary medium-temperature steaming and roasting stage, a low airflow rate is required to ensure the pork skin is fully cooked without drying out. In the subsequent high-temperature grilling stage, rapid heating and high airflow are needed for rapid heat exchange, causing the moisture inside the pork skin cells to evaporate quickly. This creates steam pressure that expands the skin, forming a honeycomb structure. The cooking results show that crispy roast pork with controlled airflow exhibits better skin expansion, a larger expanded area, and a higher expansion height.

[0168] Table 1

[0169] In one possible application, different levels of coloring and crispiness of the fries can be achieved by controlling the wind speed.

[0170] Taking French fries as an example, this study compares the effects of air frying under different wind speeds.

[0171] 1. Low wind speed program:

[0172] First, it quickly preheats to 220℃, and reminds the user to put food in after preheating is reached; second, it uses upper and lower heating elements with low fan speed to reach 220℃ for 20 minutes.

[0173] 2. Medium wind speed program:

[0174] First, it quickly preheats to 220℃ and reminds the user to put food in after preheating is reached.

[0175] Second, upper and lower heating elements + medium fan speed, 220℃, 20min.

[0176] 3. High wind speed program:

[0177] First, it quickly preheats to 220℃ and reminds the user to put food in after preheating is reached.

[0178] Second, upper and lower heating elements + high wind speed, 220℃, 20min.

[0179] As shown in Table 2, after cooking, the difference in coloring and dehydration (crispness) of the fries under different wind speeds is obvious, which can meet the needs of different users for different crispness and coloring effects.

[0180] Table 2

[0181] In an embodiment of this application, a control device 700 for a cooking device is proposed. The cooking device includes a housing, a heating component, an adjustable speed drive, and an impeller. The housing has a cooking cavity. The heating component is connected to the housing and is used to heat the inside of the cooking cavity. The adjustable speed drive is connected to the housing. The impeller is connected to the adjustable speed drive. The adjustable speed drive is used to drive the impeller to rotate. The impeller is used to drive the airflow inside the cooking cavity.

[0182] As shown in Figure 6, the control device 700 of the cooking equipment includes:

[0183] The acquisition module 710 is used to acquire target cooking parameters, including the target speed of the adjustable speed drive.

[0184] The control module 720 is used to control the operation of the adjustable speed drive according to the target speed.

[0185] The output speed of the adjustable speed drive can be adjusted. On the one hand, different wind speeds can be used to adjust the crispness and color of food. On the other hand, different wind speeds can be controlled at different stages of food cooking to achieve better cooking results and meet the cooking needs of users.

[0186] Before cooking, the target cooking parameters are obtained, including the target rotation speed. Based on the target rotation speed, the adjustable rotation speed drive is controlled to operate. The steam oven and microwave oven proposed in this application, which can control the airflow speed inside the cooking cavity, can adjust the speed of hot air flow inside the cooking cavity through the air control module according to the cooking needs of different foods, thereby achieving airflow control during the cooking process and achieving better cooking results.

[0187] In some embodiments, before the step of obtaining the target cooking parameters, the obtaining module is further configured to: receive user input, and the control module is further configured to: determine the target cooking mode based on the user input; determine the target cooking parameters based on the target cooking mode, wherein the target cooking parameters are associated with the target cooking mode.

[0188] Users can choose cooking modes according to their needs. For example, the cooking equipment has a menu. Users can select from the menu, and each menu has corresponding target cooking parameters. The cooking equipment determines the target cooking parameters based on the user's selection, thereby realizing the cooking of the ingredients.

[0189] In some embodiments, before the step of obtaining the target cooking parameters, the obtaining module is further configured to: receive user input; the control module is further configured to: determine the target cooking effect of the ingredients based on the user input, the target cooking effect including target crispness and / or target coloring; and determine the target cooking parameters based on the target cooking effect, the target cooking parameters being associated with the target cooking effect.

[0190] Users can select the crispness and color of the ingredients according to their needs. The cooking equipment has a pre-stored correspondence between crispness and color and target cooking parameters. After the user selects the crispness and color, the cooking equipment retrieves the corresponding target cooking parameters to cook the ingredients.

[0191] Before cooking, the target cooking parameters are obtained, including the target rotation speed. Based on the target rotation speed, the adjustable rotation speed drive is controlled. The steam-bake and microwave-steam oven product proposed in this application, which can control the air speed inside the cooking cavity, can adjust the speed of the hot air flow inside the cavity according to the cooking needs of different foods or according to the user's selection of browning and crispness. This achieves air speed control during the cooking process, resulting in better cooking effects. While achieving multiple levels of crispness and browning adjustment, it also makes crispy meat, air-fried foods, and other foods crispier and better in taste.

[0192] In some embodiments, the cooking parameters may optionally include a target cooking temperature and a target cooking time; the control method of the cooking device may further include controlling the operation of the heating component according to the target cooking temperature and the target cooking time.

[0193] Users can select any cooking mode with an impeller (such as back tube + impeller, top tube + impeller, top and bottom tubes + impeller, etc.) and set the temperature, time, and fan speed to achieve the desired cooking effect.

[0194] In some embodiments, the heating assembly includes a first heating element, a second heating element, and a third heating element. The cooking cavity has an opening. The first heating element is disposed on the inner wall of the cooking cavity opposite to the opening. The second heating element is disposed on the top wall of the cooking cavity. The third heating element is disposed on the bottom wall of the cooking cavity.

[0195] The target cooking parameters also include the target cooking temperature. After obtaining the target cooking parameters, the control module is also used to control the operation of at least one of the first heating element, the second heating element, and the third heating element according to the target cooking temperature.

[0196] Given a target cooking temperature, heating can be achieved using a single heating element, a combination of two heating elements, or all three heating elements operating simultaneously. For example, at a lower target cooking temperature, one or two heating elements are sufficient, while at a higher target cooking temperature, three heating elements operating simultaneously can quickly meet the heating requirements.

[0197] In some embodiments, the target cooking parameter further includes a target cooking temperature. The acquisition module is also configured to: acquire the temperature inside the cooking cavity when the heating element is operating. The control module is also configured to: maintain or increase the heating power of the heating element when the temperature inside the cooking cavity is lower than the target cooking temperature; and decrease the heating power of the heating element when the temperature inside the cooking cavity is higher than the target cooking temperature.

[0198] With a target cooking temperature determined, the temperature inside the cooking cavity needs to be continuously monitored during the cooking process. If the temperature inside the cooking cavity hasn't reached the target temperature during the heating phase, the heating power of the heating element can be maintained to keep the temperature rising. If the heating phase has passed and the temperature inside the cooking cavity still hasn't reached the target temperature, the heating power of the heating element needs to be increased to bring the temperature to the target temperature. If the temperature inside the cooking cavity is higher than the target cooking temperature, it indicates that the heating power of the heating element is too high; in this case, the heating power can be reduced to prevent the temperature inside the cooking cavity from becoming too high. By using this method, the temperature inside the cooking cavity can be maintained near the target cooking temperature, which is beneficial for improving the cooking effect on the food.

[0199] In some embodiments, the target cooking parameters further include a target cooking temperature. After obtaining the target cooking parameters, the obtaining module is further configured to: obtain target rotation speed and target cooking temperature for multiple cooking stages, assuming the cooking process has multiple cooking stages. The control module is further configured to: control the operation of the adjustable speed drive according to the target rotation speed, and control the operation of the heating component according to the target cooking temperature.

[0200] When a cooking process has multiple stages, the target rotation speed and target cooking temperature may differ for each stage. The adjustable rotation speed drive and heating element can be controlled according to the target rotation speed and target cooking temperature for each stage. Different cooking stages allow for targeted adjustments to the target rotation speed and target cooking temperature for different ingredients, which helps improve the crispness and browning of the ingredients, thus enhancing the overall cooking effect.

[0201] As shown in Figure 7, in an embodiment of this application, a control device 800 for a cooking device is proposed, including a memory 810 and a processor 820. The memory 810 stores programs or instructions that can be run on the processor 820. When the program or instructions are executed by the processor 820, they implement the steps of the control method for the cooking device as described in any of the above embodiments and can achieve the same technical effect, which will not be repeated here.

[0202] In the embodiments of this application, a readable storage medium is proposed, on which a program or instruction is stored, wherein when the program or instruction is executed by a processor, it implements the steps of the control method of the cooking device as described in any of the above embodiments, and can achieve the same technical effect, which will not be repeated here.

[0203] The methods can be implemented in various ways depending on specific features and / or example applications. For example, these methods can be implemented by a combination of hardware, firmware, and / or software. For instance, in a hardware implementation, the processor can be implemented in one or more application-specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field-programmable gate arrays (FPGAs), controllers, microcontrollers, microprocessors, electronic devices, other device units for performing the functions described above, and / or combinations thereof.

[0204] A computer-readable storage medium can be a tangible device that holds and stores instructions for use by an instruction execution device. A computer-readable storage medium can be an electronic storage device, a magnetic storage device, an optical storage device, an electromagnetic storage device, a semiconductor storage device, or any suitable combination of the foregoing, but is not limited thereto. A non-exhaustive list of more specific examples of computer-readable storage media includes: portable computer floppy disks, hard disks, random access memory (RAM), read-only memory (ROM), erasable and programmable read-only memory (EPROM or flash memory), static random access memory (SRAM), portable optical disc read-only memory (CD-ROM), digital universal disk (DVD), memory cards, floppy disks, encoding mechanical devices (e.g., punched cards or grooves with raised structures for recording instructions), and any suitable combination of the foregoing. The computer-readable storage medium used herein should not be construed as the transmission of signals themselves, such as radio waves or other freely propagating electromagnetic waves, electromagnetic waves propagating through waveguides or other transmission media, or electrical signals transmitted through wires.

[0205] As shown in Figures 8, 9 and 10, according to one embodiment of this application, a cooking device is proposed, comprising: a housing 100 and a dehumidification assembly 2.

[0206] Specifically, the housing 100 includes a cooking cavity 10, which has an air inlet 102 and an exhaust outlet 104. The dehumidification assembly 2 is located on the outside of the cooking cavity 10. The dehumidification assembly 2 includes an air supply unit 20 and a valve body 22. The valve body 22 includes a first connecting end 221 and a second connecting end 222. The air supply unit 20 is connected to the first connecting end 221, and the second connecting end 222 is connected to the air inlet 102. The valve body 22 has an open state and a closed state. When the valve body 22 is in the open state, the first connecting end 221 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. When the valve body 22 is in the closed state, the first connecting end 221 and the second connecting end 222 are disconnected.

[0207] The cooking equipment provided in this application includes a housing 100 and a dehumidification assembly 2. The housing 100 includes a cooking chamber 10 for cooking food. The cooking chamber 10 is provided with an air inlet 102 and an exhaust outlet 104. The dehumidification assembly 2 is disposed on the housing 100 outside the cooking chamber 10. The dehumidification assembly 2 includes an air supply unit 20 and a valve body 22. The first connecting end 221 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 chamber 10. Thus, when the valve body 22 is in the open state, the first connecting end 221, 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 chamber 10 through the valve body 22 and the air inlet 102. As the pressure inside the cooking chamber 10 gradually increases, the air inside the cooking chamber 10 is discharged through the exhaust outlet 104, thereby achieving dehumidification of the cooking chamber 10 and improving dehumidification efficiency and safety performance. When the valve body 22 is in the closed state, the first connection end 221 and the second connection end 222 are disconnected, so the hot and humid air in the cooking cavity 10 cannot flow through the valve body 22 to the location of the air supply unit 20, thus avoiding damage to other parts of the cooking equipment.

[0208] Optionally, the air supply unit 20 refers to a device that can provide an air source with pressure higher than atmospheric pressure, including but not limited to fans, blowers, air pumps, air compressors, high-pressure air ducts, etc.

[0209] Optionally, the air supply unit 20 includes an air outlet, which is connected to the first connection terminal 221.

[0210] As shown in Figures 8 and 9, the arrows indicate the direction of airflow.

[0211] As shown in Figures 8 and 10, in some embodiments, the valve body 22 may optionally include a valve seat 23 and a valve core 24.

[0212] Specifically, the valve seat 23 includes a first connecting end 221 and a second connecting end 222; the valve core 24 is rotatably disposed in the valve seat 23 for connecting the first connecting end 221 and the second connecting end 222, or for blocking the first connecting end 221 and the second connecting end 222.

[0213] In this embodiment, the valve body 22 includes a valve seat 23 and a valve core 24. The valve seat 23 is provided with a first connecting end 221 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, 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 221 and the second connecting end 222, thereby allowing the air supply unit 20 to supply air into the cooking cavity 10 through the valve body 22 and the air inlet 102. This allows the humid and hot air in the cooking cavity 10 to be discharged through the exhaust port 104 of the cooking cavity 10, achieving dehumidification within the cooking cavity 10 and thus 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 221 and the second connection end 222, thereby disconnecting the first connection end 221 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.

[0214] As shown in Figure 10, in some embodiments, the valve body 22 may optionally include a drive member 25, disposed on the valve seat 23 and connected to the valve core 24, for driving the valve core 24 to rotate within the valve seat 23.

[0215] In this embodiment, the valve body 22 further includes a drive member 25, which is disposed on the valve seat 23 and connected to the valve core 24 to drive the valve core 24 to rotate within the valve seat 23, thereby realizing automated control of the movement of the valve core 24.

[0216] Optionally, the valve core 24 can rotate 360° within the valve seat 23.

[0217] Optionally, the cooking device also includes a control unit connected to the drive unit 25 and the air supply unit 20. A temperature sensor is installed inside the cooking cavity 10 and is electrically connected to the control unit. When the temperature sensor detects that the temperature inside the cooking cavity 10 has reached the set temperature, the control unit controls the drive unit 25 to move the valve core 24, thereby connecting the first connection end 221 and the second connection end 222. Simultaneously, the control unit controls the air supply unit 20 to supply air into the cooking cavity 10, achieving dehumidification within the cooking cavity 10. When the cooking program ends, the control unit controls the drive unit 25 to move the valve core 24, thereby disconnecting the first connection end 221 and the second connection end 222, and simultaneously controls the air supply unit 20 to stop operating.

[0218] Optionally, the drive unit 25 includes a motor.

[0219] Optionally, the drive unit 25 includes an AC motor.

[0220] As shown in Figure 10, in some embodiments, the valve core 24 optionally includes: a rotating drum portion 240, which is rotatably connected to the valve seat 23. The rotating drum portion 240 is provided with a channel 242, which passes through the rotating drum portion 240 along the radial direction B. A driving member 25 is connected to the rotating drum portion 240 and is used to drive the rotating drum portion 240 to rotate around the axis A 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 221 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 221 and the second connecting end 222.

[0221] 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 along B. The driving member 25 is connected to the rotating drum portion 240 to drive the rotating drum portion 240 to rotate around the axis A 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 221 and the second connecting end 222 respectively, so that the first connecting end 221 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 221 and the second connecting end 222, so that the first connecting end 221 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.

[0222] It is understandable that the rotating drum 240 has its own axis A, and the driving member 25 drives the rotating drum 240 to rotate around its own axis A, which can realize the opening and closing of the valve body 22, and reduce the space occupied by the rotation of the rotating drum 240, thereby reducing the space occupied by the valve body 22.

[0223] Optionally, the drive member 25 can drive the rotating drum 240 to rotate 360° along the axis A of the rotating drum 240.

[0224] Optionally, the rotating cylinder 240 is a solid column, or the portion of the rotating cylinder 240 with the channel 242 is a solid structure, with the channel 242 penetrating the portion containing the solid structure.

[0225] In some embodiments, after the driving member 25 drives the rotating drum portion 240 to rotate a first angle around the axis A of the rotating drum portion 240 in a first direction, the channel 242 on the rotating drum portion 240 connects the first connecting end 221 and the second connecting end 222, realizing the connection between the air supply unit 20 and the cooking cavity 10. With the valve body 22 in the open state, after the driving member 25 drives the rotating drum portion 240 to rotate a second angle in the first direction, the wall surface of the rotating drum portion 240 blocks the first connecting end 221 and the second connecting end 222, realizing the interception of the flow at the first connecting end 221 and the second connecting end 222. The first direction can be either a clockwise or counterclockwise direction around the circumference of the rotating drum portion 240, and the first angle and the second angle can be the same or different. Optionally, both the first angle and the second angle are 90°.

[0226] In some embodiments, after the driving member 25 drives the rotating drum portion 240 to rotate a third angle along the axis A of the rotating drum portion 240 in the first direction, the channel 242 on the rotating drum portion 240 connects the first connecting end 221 and the second connecting end 222, realizing the connection between the air supply unit 20 and the cooking cavity 10. With the valve body 22 in the open state, after the driving member 25 drives the rotating drum portion 240 to rotate a third angle along the second direction, the wall surface of the rotating drum portion 240 blocks the first connecting end 221 and the second connecting end 222, realizing the interception of the flow at the first connecting end 221 and the second connecting end 222. The first direction and the second direction are opposite. The specific value of the third angle can be set according to the actual situation. Optionally, the third angle is equal to 90°.

[0227] As shown in FIG10, 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 driving the rotating drum portion 240 to rotate through the connecting portion 244.

[0228] 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. At the same time, 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.

[0229] Optionally, the output shaft of the drive unit 25 is a square hole shaft, and the connecting part 244 is provided with a square hole that is adapted to the square hole shaft. The square hole shaft is installed in the square hole to realize the transmission of power.

[0230] As shown in Figure 10, in some embodiments, optionally, the dehumidification assembly 2 further includes: at least two microswitches 26 disposed on the valve seat 23 and electrically connected to the drive member 25, and a trigger part 246 provided on the connection part 244. The trigger part 246 is located outside the valve seat 23. When the valve body 22 is in the open state, the trigger part 246 triggers at least one microswitch 26, and when the valve body 22 is in the closed state, the trigger part 246 triggers another microswitch 26.

[0231] In this embodiment, the dehumidification assembly 2 further includes at least two microswitches 26. A trigger part 246 is provided on the connecting part 244, and the trigger part 246 is disposed opposite to the at least two microswitches 26 to realize the triggering of the at least two microswitches 26. When the driving member 25 drives the rotating drum part 240 to move through the connecting part 244, the trigger part 246 moves with the connecting part 244. When the valve body 22 is in the open state, the trigger part 246 triggers at least one microswitch 26 and feeds back to the driving member 25, so that the driving member 25 controls the rotating drum part 240 to remain in the state of conducting the first connecting end 221 and the second connecting end 222; when the valve body 22 is in the closed state, the trigger part 246 triggers another microswitch 26 and feeds back to the driving member 25, so that the driving member 25 controls the rotating drum part 240 to remain in the state of blocking the first connecting end 221 and the second connecting end 222.

[0232] As shown in Figure 10, in some embodiments, the valve seat 23 may optionally include a seat body 231 and a cover body 232. The cover body 232 is disposed opposite to and connected to the seat body 231 along the axis A of the rotating cylinder portion 240. The rotating cylinder portion 240 is located between the base and the cover body 232. The seat body 231 and the cover body 232 together form a first connecting end 221 and a second connecting end 222.

[0233] In this embodiment, the valve seat 23 includes a seat body 231 and a cover body 232. The seat body 231 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 231 and the cover body 232 enclose a first connecting end 221 and a second connecting end 222, realizing communication with the air supply unit 20 and the air inlet 102.

[0234] It is understandable that the base 231 and the cover 232 together form the first connecting end 221 and the second connecting end 222.

[0235] As shown in Figure 10, in some embodiments, the dehumidification component 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.

[0236] In this embodiment, the dehumidification component 2 also 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 setting position.

[0237] In some embodiments, the air duct 27 may optionally include a silicone tube or a rubber tube.

[0238] 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.

[0239] As shown in Figure 8, in some embodiments, the housing 100 may optionally include: a mounting cavity 12 located on one side of the cooking cavity 10, and a dehumidification assembly 2 disposed in the mounting cavity 12.

[0240] In this embodiment, the dehumidification component 2 is disposed within the mounting cavity 12 to protect the dehumidification component 2.

[0241] Optionally, the mounting cavity 12 is located at the top of the cooking cavity 10.

[0242] As shown in Figure 8, in some embodiments, the cooking device may optionally further include an electrical component 3 and a cooling fan 4.

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.

[0244] Optionally, the cooling fan 4 includes an axial fan.

[0245] Optionally, the electrical component 3 includes a control device (e.g., a control board), a magnetron, a waveguide, a relay, a capacitor, etc.

[0246] In some embodiments, the air inlet 102 may be disposed on at least one of the top wall, the side wall, and the bottom wall of the cooking cavity 10.

[0247] In this embodiment, the air inlet 102 is disposed on at least one of the top wall, side wall, and bottom wall of the cooking cavity 10, so as to increase the diversity of the placement of the air inlet 102.

[0248] In some embodiments, the cooking cavity 10 may optionally include a cooking opening 106, with the vent 104 and the cooking opening 106 located on the same side of the cooking cavity 10.

[0249] 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 from being blocked and ensuring the reliability of the dehumidification operation.

[0250] Optionally, the vent 104 is located above the cooking opening 106 and exposed in the door of the cooking appliance, wherein the door of the cooking appliance is used to open or close the cooking opening 106.

[0251] In some embodiments, the vent 104 is optionally 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.

[0252] In this embodiment, the vent 104 can be located at the top of the cooking opening 106 to avoid scalding the user. The vent 104 can be located near one of the opposite sides of the cooking cavity 10, optionally, the vent 104 is located at the upper left or upper right of the cooking cavity 10.

[0253] Optionally, valve body 22 includes a butterfly on / off valve.

[0254] Optionally, the air supply unit 20 includes a DC fan.

[0255] As shown in Figure 9, in some embodiments, the cooking device may optionally include a heating element 5, which is disposed in the housing 100 and is used to heat the cooking cavity 10.

[0256] In this embodiment, the cooking device further includes a heating element 5, which is used to heat the cooking cavity 10 to cook the food inside the cooking cavity 10.

[0257] In some embodiments, the heating element 5 may optionally include at least one of a heating tube, a hot air assembly, a steam generator, and a microwave generator.

[0258] In this embodiment, the heating element can radiate heat into the cooking cavity 10 to achieve cooking such as grilling; the hot air assembly can deliver hot air into the cooking cavity 10 to achieve grilling; the steam generator can deliver steam into the cooking cavity 10 to achieve steaming; and the microwave generator can feed microwaves into the cooking cavity 10 to achieve microwave cooking. The heating element 5 in this application can be at least one of the heating element, hot air assembly, steam generator, and microwave generator to achieve various cooking methods such as grilling, steaming, and drying, as well as combinations of these methods.

[0259] Optionally, the heating element 5 is disposed in at least one of the top, back, bottom and side walls of the cooking cavity 10.

[0260] Optionally, the microwave generator includes a magnetron, a waveguide, etc. The cooling fan 4 is used to cool the magnetron and the waveguide.

[0261] In some embodiments, the cooking equipment may optionally include any one of a microwave oven, oven, steam oven, steam oven, microwave-steam-roaster, or air fryer.

[0262] In this embodiment, the cooking device can be any one of a microwave oven, oven, steam oven, steam oven, microwave-steam-roast machine, or air fryer.

[0263] In practical applications, the dehumidification component 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 dehumidification component 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.

[0264] Specifically, the dehumidification assembly 2 includes a base 231, a cover 232, a rotating drum 240, a DC fan (e.g., an air supply unit 20), an AC motor, a micro switch 26, and an air duct 27. The rotating drum 240 has a butterfly-shaped vent (e.g., channel 242) and is connected to the base 231 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 26, 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 square-hole shaft. The air duct 27 is connected to the base 231, and the DC fan serves as the air intake source, blowing air into the cooking cavity 10.

[0265] As shown in Figure 11, the entire working process of the butterfly valve dehumidification structure is as follows:

[0266] After the user selects a cooking menu with humidity control, they add ingredients and start cooking. When the temperature inside the cooking cavity 10 rises to the user-set temperature, the program controls the butterfly valve to operate, and the rotating drum 240 is driven to rotate by an AC motor. When the vent on the rotating drum 240 rotates 90° and connects with the air duct 27 and the DC fan, the micro switch 26 is triggered to stop. At this time, the DC fan is directly connected to the cooking cavity 10 through the air duct 27, and the DC fan blows air 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 squeezing out the original moisture from the exhaust port 104, achieving the purpose of reducing the humidity inside the cooking cavity 10. When the cooking program ends, the AC motor is started to drive the rotating drum 240 to rotate 90°, at which point the micro switch 26 is triggered to stop. At this time, the vent on the rotating drum 240 is orthogonal to the air duct 27, thereby blocking the airflow between the cooking cavity 10 and the DC fan. The DC fan stops working, and the dehumidification function is turned off. When cooking is finished, the user can simply open the door to remove the cooked food.
