[0043] The present application embodiment provides a cooking device, please refer to Figures 1 to 6 , comprising a housing 1, a detection device 2, a fan 3 and a control device 4. The housing 1 has a cooking cavity 1a and an exhaust passage 1b, the exhaust passage 1b connects the cooking cavity 1a with the external environment, and the exhaust passage 1b is used to exhaust the gas in the cooking cavity 1a.

[0044] In one embodiment, please refer to Figures 2 to 3 The housing 1 includes a housing assembly 11 and a cavity module 12 having a cooking cavity 1a, wherein the housing assembly 11 is disposed outside at least a portion of the structure of the cavity module 12. That is, the housing assembly 11 may be disposed outside the entire cavity module 12, or may be disposed outside a portion of the structure of the cavity module 12.

[0045] Exemplarily, the cavity module 12 may include a cavity front plate, a cavity top plate 121, a cavity lower plate, a cavity right plate, a cavity left plate and a cavity rear plate, and the cavity front plate, the cavity top plate 121, the cavity lower plate, the cavity right plate, the cavity left plate and the cavity rear plate together form a cooking cavity 1a.

[0046] Exemplarily, the housing 1 includes a heat insulating layer, the housing assembly 11 is disposed on the outside of the cavity module 12, and defines a storage space with the cavity module 12, and the heat insulating layer is disposed in the storage space to keep the cooking cavity 1a warm. That is, the housing assembly 11 is disposed on the outside of the cavity module 12, and the housing assembly 11 may include an upper outer cover, a lower outer cover, a right outer cover, a left outer cover, and a rear outer cover.

[0047] The cooking cavity 1a is used to contain food and cook the food, and the food can be put into the cooking cavity 1a or taken out from the cooking cavity 1a through the opening 1c of the cooking cavity 1a. The opening 1c is, for example, arranged at the front side of the housing 1.

[0048] In one embodiment, please refer to Figure 1 The cooking device includes a door body 6 covering the opening 1c for sealing the cooking cavity 1a, that is, the door body 6 can selectively open or close the opening 1c.

[0049] In one embodiment, please refer to Figure 1 To facilitate opening or closing the opening 1c, a door handle 61 is formed on the surface of the door body 6 away from the opening 1c. When the opening 1c needs to be opened or closed, the door body 6 can be opened by holding the door handle 61 to open the door body 6, thereby opening or closing the opening 1c, and then using the door body 6 to open or close the cooking cavity 1a, thereby improving the user's operating experience.

[0050] The detection device 2 is used to detect the concentration of oil smoke in the cooking cavity 1a.

[0051] The type of the detection device 2 is not limited.

[0052] In one embodiment, the detection device 2 is an oil smoke sensor. The oil smoke sensor is at least partially disposed in the cooking cavity 1a, and the oil smoke sensor is used to detect the oil smoke concentration. The oil smoke sensor has high sensitivity and is easy to install and use.

[0053] In other embodiments, the detection device 2 is a sieve sensor or a light sensor, that is, the corresponding detection principle is an electrochemical method or a photometric method.

[0054] The electrochemical method means that the detection device 2 is a sieve sensor with multiple holes. When oil fume particles enter the sensor, the holes of the sensor will receive the oil fume particles, thereby increasing the resistance of the sieve, which will affect the change of current intensity. Because there is a linear relationship (proportional relationship) between current intensity and oil fume concentration, the oil fume concentration can be calculated based on the electric field (current) intensity.

[0055] The light detection method refers to that the detection device 2 is a light sensor, which is fixedly installed in the cooking cavity 1a with two sides, one end is the transmitting end, and the other end is the receiving end. The transmitting end emits infrared light waves, which scatter light after irradiating the oil smoke particles. After the receiving end collects the light, it compares the changes of the light before and after, and thus calculates the oil smoke concentration value.

[0056] That is to say, at least part of the structure of the detection device 2 is located in the cooking cavity 1a.

[0057] The fan 3 includes a motor 31 and a first impeller 32. The motor 31 is connected to the first impeller 32 to generate a directional flow of the airflow in the exhaust passage 1b. That is, the motor 31 drives the first impeller 32 to rotate to generate airflow, so that the gas in the cooking chamber 1a flows to the external environment through the exhaust passage 1b. The control device 4 is used to adjust the speed of the motor 31 according to the oil smoke concentration detected by the detection device 2.

[0058] It is understandable that when food is baked, carbohydrates such as protein and fat contained in the food are easy to produce oil smoke after being heated to the smoke point. The oil smoke contains many harmful substances. If it cannot be removed in time, when the door is opened to take out the food, the oil smoke will enter the room and cause harm to the human body. In the related art, the fan speed is fixed, and the exhaust volume cannot be automatically adjusted according to the cooking conditions. If the exhaust fan speed is too high, the noise is large, energy consumption, and the motor life is affected; if the exhaust fan speed is too low, the exhaust volume of oil smoke cannot be satisfied. The cooking device provided in the embodiment of the present application adjusts the speed of the motor 31 based on the detection result of the detection device 2 by the control device 4 to timely discharge the oil smoke in the cooking device, realize the cleaning of the oil smoke, and reduce the impact of excessive oil smoke concentration on the health of the user. It is understandable that when the oil smoke concentration is greater than the preset concentration, the speed of the motor 31 is increased to speed up the exhaust volume, and when the oil smoke concentration is less than the preset concentration, the speed of the motor 31 is reduced to save energy, reduce noise, and extend the service life of the fan 3.

[0059] It should be noted that the specific type of the cooking device is not limited here. For example, in one embodiment, the cooking device is one of an oven, an air fryer, a steamer, and a steam oven. The present application embodiment is described by taking the cooking device as an oven as an example.

[0060] In other embodiments, the microwave heating function can be integrated into cooking devices with different functions according to user needs, so as to separate the microwave from the oven, steamer or steam oven, thereby improving the convenience of kitchen use. For example, a microwave steam oven is integrated.

[0061] The installation position of the fan 3 is not limited. In some embodiments, the fan 3 is disposed in the exhaust passage 1b, and the first impeller 32 rotates to draw the gas in the cooking cavity 1a out of the cooking cavity 1a.

[0062] In other embodiments, the fan 3 is disposed outside the exhaust passage 1b.

[0063] In one embodiment, please refer to Figure 3 to Figure 4The cooking device includes a heating element 5, a first impeller 32 for blowing air into the cooking cavity 1a, and the heating element 5 is arranged on the air flow path of the fan 3. That is, the heating element 5 can generate heat for baking food, and the first impeller 32 rotates to blow the heat into the cooking cavity, so that the heat is more evenly distributed in the cooking cavity, the food is fully cooked, and the cooking efficiency is improved. The fan 3 generates positive pressure in the cooking cavity 1a by blowing air into the cooking cavity 1a, so that the gas in the cooking cavity 1a is discharged through the exhaust channel 1b.

[0064] In one embodiment, please refer to Figure 5 The box body 1 includes a cavity top plate 121, which is configured as the top wall of the cooking cavity 1a. The top wall is provided with an air hole 121a. The fan 3 is arranged on the top side of the top wall. The heating element 5 is located in the cooking cavity 1a and is arranged on the bottom side of the air hole 121a. It can be understood that the airflow generated by the fan 3 flows into the cooking cavity 1a through the air hole 121a. That is, the airflow flows to the cooking cavity 1a under the action of the fan 3 of the cooking device, so that the airflow carrying heat can be blown vertically to the food, further improving the cooking efficiency and cooking effect.

[0065] In one embodiment, please refer to Figures 2 to 4 , the control device 4 is arranged in the space above the cavity top plate 121. It can be understood that the control device 4 can be installed on the housing assembly 11. When cooking in the cooking cavity 1a, hot air flow is generated. The control device 4 is arranged above the cavity top plate 121 to reduce the influence of the hot air flow on the control accuracy of the control device 4.

[0066] In one embodiment, please refer to Figures 3 to 6 The cooking device includes a heat dissipation duct a, which is arranged at the top of the box body 1 and is used to dissipate the heat between the shell assembly 11 and the top of the cavity module 12, that is, the heat transferred from the cooking cavity 1a to the top of the cavity top plate 121 can be dissipated to achieve heat dissipation and cooling of the box body 1 and the control device 4 located above the cavity top plate 121. That is, the hot air between the cavity module 12 and the shell assembly 11 in the cooking device is circulated with the outside air, so as to dissipate heat and cool the cooking device.

[0067] There is no limitation on the method of achieving air flow in the heat dissipation duct a.

[0068] In another embodiment, please refer to Figure 3 , Figure 4 and Figure 6 The fan 3 includes a second impeller 33, which is disposed in the heat dissipation duct a and connected to the motor 31, and is used to discharge the airflow of the heat dissipation duct a out of the cooking device. In other words, the motor 31 can drive the first impeller 32 and the second impeller 33 to work at the same time, saving the arrangement space of the motor 31 driving the second impeller 33.

[0069] The second impeller 33 may be a centrifugal impeller, that is, the fan 3 blows air toward the heat dissipation air duct a through the second impeller 33 so that the hot air between the cavity module 12 and the housing assembly 11 is discharged to the outside air.

[0070] In some embodiments, the second impeller 33 may be configured with an independent motor, that is, the second impeller 33 and the first impeller may not share a motor.

[0071] In one embodiment, please refer to Figure 3 and Figure 4 The heat dissipation air duct a is connected to the exhaust duct 1b so that the airflows in the two merge and then are discharged from the same outlet of the cooking device. That is, the gas in the cooking cavity 1a is discharged from the exhaust duct 1b and merges with the heat dissipation air duct a, and then is discharged from the cooking device through the same outlet.

[0072] For example, please refer to Figures 3 to 5 , a partial area of ​​the cavity top plate 121 protrudes toward the side away from the cooking cavity 1a to form a protruding area 121b, that is, the cavity top plate 121 protrudes toward the heat dissipation duct a to form a protruding area 121b, and the side wall of the protruding area 121b is surrounded to form an outlet duct 121c, that is, the cavity top plate 121 is connected to the cooking cavity 1a and the heat dissipation duct a through the outlet duct 121c of the protruding area 121b, that is, the hot air flow in the cooking cavity 1a can be discharged to the heat dissipation duct a through the outlet duct 121c of the protruding area 121b, and discharged to the outside together with the air flow in the heat dissipation duct a. In this embodiment, the exhaust channel 1b is formed by the outlet duct 121c, part of the heat dissipation duct a and the outlet.

[0073] Of course, the cavity top plate 121 can also be connected to the outside through the raised area 121b, that is, the hot air flow in the cooking cavity 1a can be directly discharged to the outside through the air outlet duct 121c of the raised area 121b. At this time, the air outlet duct 121c is the exhaust duct 1b.

[0074] Exemplarily, the cavity top plate 121 and the raised area 121b formed with the air outlet duct 121c are an integrated structure, for example, an integrated sheet metal part. In other words, the cavity top plate 121 is an integrated sheet metal part, a structure formed by a cold working process from the same metal plate. For example, the structure finally obtained after processes such as blanking, stamping, and bending. In this way, the structural strength and rigidity of the cavity top plate 121 can be improved.

[0075] In some specific embodiments, the same metal plate is cut into a desired shape through a punching process; stamping is performed on the cut plate to punch out a raised area 121b, wherein the portion of the plate that has not been punched and bent is a non-raised area, that is, the non-raised area is equivalent to a reference datum for the plate to undergo stamping, bending and other processes.

[0076] The main function of the oven is to heat food through the heat of the heating tube. In order to protect electrical components, plastic parts, cabinets, etc., the product needs to dissipate heat inside and outside the cooking cavity 1a. In the related art, the oven is provided with an exhaust pipe, which is fixed on the cavity top plate 121, and the hot air flow in the cooking cavity 1a is discharged through the exhaust pipe, resulting in the oven needing an extra part. In order to manufacture the part, an additional mold needs to be set up, which leads to reduced assembly efficiency and increased costs. In addition, an extra part will also increase the cumulative tolerance of the assembly of various parts to a certain extent.

[0077] The cavity top plate 121 of the cooking device provided in the embodiment of the present application has an outlet duct 121c integrally formed on the cavity top plate 121 for connecting the cooking cavity 1a and the heat dissipation duct a. That is, the hot air flow in the cooking cavity 1a can flow into the heat dissipation duct a through the outlet duct 121c and flow to the outside together with the air flow in the heat dissipation duct a, so as to discharge the hot air flow in the cooking cavity 1a. In other words, the cavity top plate 121 provided in the embodiment of the present application has an integrally formed raised area 121b surrounding the outlet duct 121c, so there is no need to additionally set up an exhaust pipe, which reduces the number of parts and the molds for manufacturing the parts. Therefore, the installation efficiency is improved, the cost is reduced, and the cumulative tolerance of the assembly of the parts is reduced.

[0078] In one embodiment, the cooking device includes a door lock switch, which is connected by a wiring harness and can control the motor 31 to stop rotating. That is, the motor 31 can be controlled to stop rotating immediately through the door lock switch, thereby improving the efficiency of disassembly or maintenance.

[0079] The door lock switch can be connected to the front plate of the cavity, and the door body 6 can be opened or closed to control the door lock switch, thereby controlling the motor 31 to stop suddenly.

[0080] Due to the door lock switch, if the first impeller 32 or the second impeller 33 needs to be replaced, the door body 6 is opened to trigger the door lock switch, so that the first impeller 32 and the second impeller 33 are stopped through the program harness, etc., and the moving parts will not be touched, so there will be no safety issues. At the same time, the effect of easy disassembly and easy maintenance is achieved.

[0081] For another aspect of the present application, please refer to Figure 7 , provides a control method for a cooking device, comprising:

[0082] S1. Obtaining preset oil fume concentration and current oil fume concentration;

[0083] S2. Based on the current oil fume concentration and the preset oil fume concentration, adjust the speed of the exhaust fan of the cooking chamber 1a.

[0084] In step S2, the exhaust fan may be the fan 3 in the above embodiment.

[0085] The present application detects the current oil fume concentration, compares the current oil fume concentration with the preset oil fume concentration to adjust the speed of the motor 31 of the fan 3, and can adjust the exhaust volume of the fan 3 in real time according to the cooking status, which is energy-saving and environmentally friendly and extends the service life of the fan 3.

[0086] In step S1, the preset oil fume concentration is obtained, including: obtaining the type of food; and obtaining the preset oil fume concentration corresponding to the type of food according to the mapping relationship between the type of food and the oil fume concentration.

[0087] It is understandable that due to the different nutrient content of different ingredients, meat contains more carbohydrates such as protein and fat, while vegetarian ingredients contain less carbohydrates such as protein and fat. Therefore, when heating different ingredients, the amount of oil smoke generated per unit time is also different, that is, the oil smoke concentration in the cooking chamber 1a is different, and even when heating some ingredients, no oil smoke is generated. The corresponding preset oil smoke concentration is obtained for different types of ingredients, so that when heating ingredients that generate more oil smoke, the exhaust intensity of the exhaust channel 1b can meet the demand for exhausting oil smoke. When heating ingredients that do not generate oil smoke, the exhaust intensity of the exhaust channel 1b is reduced to suit the cooking of ingredients and save energy.

[0088] The mapping relationship between food types and oil fume concentrations can be stored in the control device 4 in advance.

[0089] In some implementation schemes, the control device 4 stores a formula of food type and oil smoke concentration.

[0090] In other embodiments, a preset comparison table of food types and oil fume concentrations is stored in the control device 4. The preset comparison table stores the mapping relationship between food types and oil fume concentrations. It can be understood that the preset comparison table is obtained based on multiple experiments and stored in the control device 4.

[0091] In one embodiment, step S2 includes:

[0092] S21, if the current oil fume concentration is not less than the preset oil fume concentration, increasing the speed of the exhaust fan of the cooking chamber 1a;

[0093] S22: If the current oil fume concentration is less than the preset oil fume concentration, reduce the rotation speed of the exhaust fan of the cooking chamber 1a.

[0094] That is to say, the user places the desired cooking food in the cooking cavity 1a, starts the oven, and the detection device 2 works at the same time to detect the oil fume concentration value in the cooking cavity 1a in a timely manner. When the detected current oil fume concentration is greater than or equal to the preset oil fume concentration, this signal is sent to the control device 4, and the control device 4 automatically controls to increase the speed of the motor 31 of the fan 3. When the detected current oil fume concentration is less than the preset oil fume concentration, this signal is sent to the control device 4, and the control device 4 automatically controls to reduce the speed of the motor 31 of the fan 3. That is, the real-time control of the speed of the motor 31 of the fan 3 can be achieved, and the motor 31 can be adjusted according to the current cooking needs, which is intelligent and convenient, improves the user experience, saves energy, and prolongs the service life of the fan 3.

[0095] In one embodiment, if the current oil fume concentration is greater than the preset oil fume concentration, the control method further includes:

[0096] S221, obtaining the status of the range hood;

[0097] S222: Output a signal for controlling the range hood based on the state of the range hood.

[0098] It is understandable that the range hood and the cooking device are connected to the smart home network. For example, the cooking device is used in the kitchen. When the current fume concentration is greater than the preset fume concentration, the cooking device can transmit a radio signal to the smart home control assembly to obtain the state of the range hood. Based on the state of the range hood, the range hood is controlled to absorb the fume discharged into the room by the cooking device through the exhaust channel 1b. In this way, a healthy kitchen environment is created and the user experience is improved.

[0099] In one embodiment, step S222 includes:

[0100] If the state of the range hood is off, outputting an on signal for turning on the range hood;

[0101] If the state of the range hood is the on state, an increase signal for increasing the rotation speed of the range hood is output.

[0102] That is, when the range hood is turned off, the control device 4 outputs an on signal to the smart home control assembly to control the range hood to turn on; when the range hood is turned on, the control device 4 outputs an increase signal to the smart home control assembly to control the range hood to increase its speed. In this way, the cooking device and indoor fumes are discharged in time, improving the user experience.

[0103] In a third aspect of an embodiment of the present application, an electronic device is provided, comprising a processor and a memory for storing a computer service that can be run on the processor, wherein the processor is used to run the computer service to implement any of the above control methods. It can be understood that the memory can be a volatile memory or a non-volatile memory, and can also include both volatile and non-volatile memories. Among them, the non-volatile memory can be a read-only memory (ROM), a programmable read-only memory (PROM), an erasable programmable read-only memory (EPROM), an electrically erasable programmable read-only memory (EEPROM), a magnetic random access memory (FRAM), a flash memory, a magnetic surface memory, an optical disc, or a read-only optical disc (CD-ROM); the magnetic surface memory can be a disk memory or a tape memory.

The memory described in the embodiments of the present application is intended to include but is not limited to these and any other suitable types of memory.

[0104] Among them, the control method disclosed in the present invention can be applied to a processor or implemented by a processor.

In the implementation process, each step of the voice conversion method can be completed by an integrated logic circuit of hardware in the processor or an instruction in the form of software.
