Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a cooking appliance and a control method, a control device and a readable storage medium thereof. Background Art

[0002] In the related art, the spray system equipped in the cooking appliance can only spray and clean the inner wall of the cooking cavity, and its function is relatively single, which cannot meet the various needs of the cooking process and affects the user experience. Summary of the invention

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

[0004] To this end, a first aspect of the present invention provides a cooking appliance.

[0005] A second aspect of the present invention provides a method for controlling a cooking appliance.

[0006] A third aspect of the present invention provides a control device for a cooking appliance.

[0007] A fourth aspect of the present invention provides a control device for a cooking appliance.

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

[0009] A first aspect of the present invention provides a cooking utensil, comprising: a box body, the box body comprising a cooking cavity; a containing box, the containing box being used to contain liquid; a steam generator, the inlet of the steam generator being connected to the containing box, and the outlet of the steam generator being connected to the cooking cavity of the cooking utensil; wherein the liquid in the containing box can be delivered to the steam generator at a first flow rate so that the steam generator delivers steam to the cooking cavity, and the liquid in the first containing box can also be delivered to the steam generator at a second flow rate so that the steam generator delivers a vapor-liquid mixture to the cooking cavity, and the first flow rate is less than the second flow rate.

[0010] The cooking device provided by the present invention comprises a box body, the box body comprises a cooking cavity, and the cooking cavity is used to place food materials so as to cook the food materials in the cooking cavity. Specifically, a tray can be provided in the box body so that food materials can be placed on the tray for heating.

[0011] Furthermore, the cooking appliance further comprises a holding box and a steam generator, wherein the holding box is used to hold liquid, specifically water. The steam generator is connected to the holding box, so that the liquid in the holding box can be transported to the steam generator. Furthermore, during the operation of the steam generator, the liquid transported to the steam generator can be evaporated, thereby converting the liquid into steam. Furthermore, the outlet of the steam generator is connected to the cooking cavity, and after converting the liquid into steam, the steam generator can finally transport the converted steam into the cooking cavity, so as to achieve steam heating of the food in the cooking cavity.

[0012] Furthermore, the liquid in the containing box can be transported to the steam generator at a first flow rate and a second flow rate, respectively, wherein the first flow rate is smaller than the second flow rate.

[0013] Specifically, when the liquid in the container is delivered to the steam generator at a first flow rate, since the first flow rate is relatively small, during the operation of the steam generator, all the liquid delivered to the steam generator can be converted into steam, and then the steam generator delivers the converted steam to the cooking cavity to achieve steam heating of the food in the cooking cavity. That is, when the liquid in the container is delivered to the steam generator at the first flow rate, it corresponds to the steam heating function of the cooking appliance.

[0014] When the liquid in the holding box is delivered to the steam generator at the second flow rate, the second flow rate is larger than the first flow rate. Therefore, during the operation of the steam generator, part of the liquid delivered to the steam generator can be converted into steam. Specifically, the steam generator can convert 70% to 90% of the liquid into steam, and the other part still exists in the form of liquid. Then the steam generator can deliver the vapor-liquid mixture to the cooking cavity, so that the surface of the food can be rinsed with liquid while the food in the cooking cavity is steam-heated, so as to rinse the starch, grease, purine, salt and other components precipitated on the surface of the food during the heating process, thereby further improving the cooking effect of the food. That is, when the liquid in the holding box is delivered to the steam generator at the second flow rate, it corresponds to the food cleaning function of the cooking utensil. It can be understood that when the liquid in the holding box is delivered to the steam generator at the second flow rate, the outlet of the steam generator can be controlled to face the surface of the food to ensure that the liquid in the vapor-liquid mixture output by the steam generator can be sprayed on the surface of the food to rinse the substances precipitated on the surface of the food.

[0015] Specifically, during the cooking process, the user can first select the steam heating function of the cooking utensil. During the steam heating process, the starch, oil, purine, salt and other components inside the food gradually precipitate to the surface of the food. After the steam heating lasts for a certain period of time, the user can adjust the cooking utensil to perform the food cleaning function, and rinse off the substances precipitated on the surface of the food by outputting a vapor-liquid mixture. After the rinsing lasts for a certain period of time, the user can set the cooking utensil to the steam heating function again to complete the steam heating process of the food.

[0016] The cooking utensil provided by the present invention controls the liquid in the holding box of the cooking utensil to be transported to the steam generator at a first flow rate and a second flow rate, respectively, so that the cooking utensil can respectively realize the steam heating function and the food cleaning function. Specifically, when the liquid in the holding box is transported to the steam generator at a first flow rate, the steam generator converts all the liquid into steam to realize the steam heating function of the cooking utensil. When the liquid in the holding box is transported to the steam generator at a second flow rate, the steam generator converts part of the liquid into steam, thereby realizing the transport of a vapor-liquid mixture to the surface of the food, so as to realize the cleaning of the food.

[0017] In addition, the control method of the cooking appliance in the above technical solution provided by the present invention may also have the following additional technical features:

[0018] In the above technical solution, further, the cooking appliance also includes: a first nozzle, which is arranged in the cooking cavity, the inlet of the first nozzle is connected to the outlet of the steam generator, and the first nozzle can rotate in the cooking cavity.

[0019] In this technical solution, the cooking appliance may also be provided with a first nozzle. Specifically, the first nozzle is provided in the cooking cavity, and the inlet of the first nozzle is connected to the outlet of the steam generator. During the operation of the steam generator, the generated steam or the vapor-liquid mixture can be delivered to the cooking cavity through the nozzle. In addition, during the process of delivering the vapor-liquid mixture to the cooking cavity, the angle of the first nozzle can be adjusted so that the outlet of the first nozzle faces the surface of the food in the cooking cavity, so as to ensure that the vapor-liquid mixture can be sprayed on the surface of the food, and ensure the cleaning effect of the precipitates on the surface of the food.

[0020] Furthermore, the cooking appliance can also realize a cooking cavity cleaning function. Specifically, when realizing the cooking cavity cleaning function of the cooking appliance, the steam generator can be turned off, and the liquid in the containing box can be controlled to be transported to the steam generator at a third flow rate. At this time, the steam generator is not turned on, so the liquid will not be converted into steam, but directly transported to the cooking cavity in a liquid state through the first nozzle, thereby realizing cleaning of the cooking cavity. Furthermore, during the cleaning process, the first nozzle can be controlled to rotate in the cooking cavity, so as to spray the liquid onto the circumferential side wall of the cooking cavity, thereby improving the cleaning effect of the cooking cavity.

[0021] In any of the above technical solutions, further, the containing box includes a first containing box, and the cooking utensil also includes: a first pump body, the inlet of the first pump body is connected to the first containing box, and the outlet of the first pump body is connected to the steam generator, wherein, when the first pump body operates at a first power, the liquid in the first containing box can be delivered to the steam generator at a first flow rate, and when the first pump body operates at a second power, the liquid in the first containing box can be delivered to the steam generator at a second flow rate.

[0022] In this technical solution, the cooking appliance may further include a first pump body, through which the liquid in the containing box can be driven to be transported to the steam generator. Specifically, the containing box may include a first containing box, and when the first pump body operates at a first power, the liquid in the first containing box can be driven to be transported to the steam generator at a first flow rate, thereby realizing the steam heating function of the cooking appliance.

[0023] Accordingly, when the first pump body is operated at the second power, the liquid in the first containing box can be driven to be transported to the steam generator at the second flow rate. The steam generator can then convert part of the liquid into steam and transport the vapor-liquid mixture into the cooking cavity to clean the surface of the food in the cooking cavity. It can be understood that the first power is less than the second power, and accordingly, the first flow rate is less than the second flow rate.

[0024] Furthermore, when the cooking cavity cleaning function is realized, the steam generator is stopped first, and the first pump body is controlled to operate at the third power, so that the liquid in the first containing box can be delivered to the steam generator at the third flow rate, and then delivered to the cooking cavity through the first nozzle, and the first nozzle is controlled to rotate to realize the cleaning of the circumferential side wall in the cooking cavity. It can be understood that the third power of the first pump body is greater than the second power and the first power, and accordingly, the third flow rate is greater than the second flow rate and the first flow rate.

[0025] In any of the above technical solutions, further, the containing box includes a second containing box, and the cooking utensil also includes: a second pump body, the inlet of the second pump body is connected to the second containing box; a second nozzle, arranged in the cooking cavity, the inlet of the second nozzle is connected to the outlet of the second pump body, and the second nozzle can rotate in the cooking cavity; wherein the second pump body is used to transport the liquid in the second containing box to the cooking cavity through the second nozzle.

[0026] In this technical solution, the container box may further include a second container box, that is, the cooking utensil includes a first container box and a second container box. Further, the cooking utensil further includes a second pump body and a second nozzle, the inlet of the second pump body is connected to the second container box, the second nozzle is connected to the outlet of the second pump body, and the second nozzle is arranged in the cooking cavity. That is, the liquid in the first container box of the cooking utensil can be transported to the cooking cavity through the steam generator, and the liquid in the second container box does not need to pass through the steam generator, and can be directly transported to the cooking cavity through the second nozzle under the drive of the second pump body.

[0027] Specifically, when the cooking appliance realizes the steam heating function, the first pump body can be turned on to operate at a first power, so that the liquid in the first containing box is transported to the steam generator at a first flow rate, and then the liquid is converted into steam and transported to the cooking cavity to realize the steam heating function.

[0028] Furthermore, when the food cleaning function of the cooking utensil needs to be realized, there is no need to adjust the operating power of the first pump body. The second pump body can be directly turned on to allow the liquid in the second containing box to be transported to the cooking cavity, and the second nozzle can be controlled to face the surface of the food to achieve cleaning of the surface of the food.

[0029] By setting up the second containing box and the second pump body, the steam delivery part can be separated from the liquid delivery part to ensure the delivery amount of steam and liquid, avoid mutual influence between steam delivery and liquid delivery, and thus ensure the heating and cleaning effects of the ingredients in the cooking cavity.

[0030] Furthermore, when realizing the cleaning function of the cooking cavity, the operation of the first pump body can be stopped, and the liquid in the second containing box can be directly delivered to the cooking cavity through the second nozzle through the operation of the second pump body, and the second nozzle can be controlled to rotate in the cooking cavity to realize the cleaning of the circumferential inner wall of the cooking cavity.

[0031] In any of the above technical solutions, further, the cooking appliance also includes: a recovery box, which is arranged at the bottom of the box body, and the recovery box is connected to the cooking cavity and is used to recover liquid flowing out of the cooking cavity.

[0032] In this technical solution, a recycling box may be provided at the bottom of the box, and the recycling box is connected to the cooking cavity. Specifically, a through hole may be provided on the bottom wall of the box, and the through hole may be opposite to the opening of the recycling box, so that the cooking cavity and the recycling box are connected. During cooking or cleaning, the liquid inside the cooking cavity can flow to the bottom of the cooking cavity under gravity, and flow into the recycling box through the through hole at the bottom of the box, so as to recycle waste water and ensure the cleanliness of the cooking utensil during use.

[0033] In any of the above technical solutions, further, the cooking appliance also includes: a liquid level detection component, which is arranged in the recovery box and is used to detect the liquid level of the liquid in the recovery box.

[0034] In this technical solution, by arranging a liquid level detection component in the recovery box, real-time detection of the liquid level in the recovery box can be achieved. When the liquid level in the recovery box reaches a preset height, it indicates that there is a lot of liquid in the recovery box, and the user needs to clean the liquid in the recovery box in time to avoid overflow of the liquid in the recovery box.

[0035] According to a second aspect of the present invention, a control method for a cooking appliance is proposed, which is used for the cooking appliance of any one of the above technical solutions. The control method includes: in response to a cooking instruction, controlling the liquid in the storage box to be delivered to the steam generator at a first flow rate; controlling the operation of the steam generator to deliver steam to the cooking cavity; and in response to an instruction to clean the food, controlling the liquid in the storage box to be delivered to the cooking cavity in the form of a vapor-liquid mixture.

[0036] The control method of the cooking appliance provided by the present invention can deliver steam or a vapor-liquid mixture into the cooking cavity to achieve steam heating of food in the cooking cavity or cleaning of the surface of the food.

[0037] Specifically, when the liquid in the container is delivered to the steam generator at a first flow rate, since the first flow rate is relatively small, during the operation of the steam generator, all the liquid delivered to the steam generator can be converted into steam, and then the steam generator delivers the converted steam to the cooking cavity to achieve steam heating of the food in the cooking cavity. That is, when the liquid in the container is delivered to the steam generator at the first flow rate, it corresponds to the steam heating function of the cooking appliance.

[0038] Furthermore, when the surface of the food needs to be cleaned, a food cleaning instruction can be input to transport the liquid in the holding box into the cooking cavity and spray it onto the surface of the food to clean the surface of the food.

[0039] In actual operation, the user can first select the steam heating function of the cooking utensil, that is, input the cooking instructions. During the steam heating process, the starch, oil, purine, salt and other components inside the food gradually precipitate to the surface of the food. After the steam heating lasts for a certain period of time, the user can adjust the cooking utensil to perform the food cleaning function, that is, input the food cleaning quality, so as to output the vapor-liquid mixture to rinse off the substances precipitated on the surface of the food. After the rinsing lasts for a certain period of time, the user can re-set the cooking utensil to the steam heating function to complete the steam heating process of the food.

[0040] In any of the above technical solutions, further, the step of controlling the liquid in the containing box to be delivered to the cooking cavity in the form of a vapor-liquid mixture includes: controlling the liquid in the containing box to be delivered to the steam generator at a second flow rate; controlling the operation of the steam generator to deliver the vapor-liquid mixture to the cooking cavity.

[0041] In this technical solution, when it is necessary to clean the surface of the food in the cooking cavity, the liquid in the holding box can be controlled to be transported to the steam generator at a second flow rate. The second flow rate is larger than the first flow rate. Therefore, during the operation of the steam generator, part of the liquid transported to the steam generator can be converted into steam. Specifically, the steam generator can convert 70% to 90% of the liquid into steam, and the other part still exists in the form of liquid. Then, the steam generator can transport the vapor-liquid mixture into the cooking cavity, so that the surface of the food can be rinsed with liquid while the food in the cooking cavity is steam-heated, so as to rinse off the starch, grease, purine, salt and other components precipitated on the surface of the food during the heating process, thereby further improving the cooking effect of the food. That is, when the liquid in the holding box is transported to the steam generator at the second flow rate, it corresponds to the food cleaning function of the cooking utensil. It can be understood that when the liquid in the container is delivered to the steam generator at a second flow rate, the outlet of the steam generator can be controlled to face the surface of the food to ensure that the liquid in the steam-liquid mixture output by the steam generator can be sprayed onto the surface of the food, so as to rinse the substances precipitated on the surface of the food.

[0042] In any of the above technical solutions, further, in response to the cooking cavity cleaning instruction, the liquid in the containing box is controlled to be delivered to the steam generator at a third flow rate; the steam generator is controlled to stop running; the first nozzle connected to the steam generator is controlled to rotate in the cooking cavity; wherein the third flow rate is greater than the second flow rate.

[0043] In this technical solution, the cooking appliance can also realize the cooking cavity cleaning function. Specifically, in response to the cooking cavity cleaning instruction of the cooking appliance, the steam generator can be turned off, and the liquid in the containing box is controlled to be delivered to the steam generator at a third flow rate. At this time, the steam generator is not turned on, so the liquid will not be converted into steam, but directly delivered to the cooking cavity in a liquid state through the first nozzle, thereby realizing the cleaning of the cooking cavity. Furthermore, during the cleaning process, the first nozzle can be controlled to rotate in the cooking cavity, so as to spray the liquid onto the circumferential side wall of the cooking cavity, thereby improving the cleaning effect of the cooking cavity.

[0044] In any of the above technical solutions, further, the containing box includes a first containing box and a second containing box, and the step of controlling the liquid in the containing box to be delivered to the cooking cavity in the form of a vapor-liquid mixture includes: controlling the liquid in the first containing box to be delivered to the steam generator at a first flow rate; controlling the operation of the steam generator to deliver steam to the cooking cavity; and controlling the liquid in the second containing box to be delivered to the cooking cavity.

Furthermore, the cooking utensil also includes a second pump body and a second nozzle, the inlet of the second pump body is connected to the second containing box, the second nozzle is connected to the outlet of the second pump body, and the second nozzle is arranged in the cooking cavity. That is, the liquid in the first containing box of the cooking utensil can be transported to the cooking cavity through the steam generator, and the liquid in the second containing box does not need to pass through the steam generator, and can be directly transported to the cooking cavity through the second nozzle under the drive of the second pump body.

[0046] Specifically, when the cooking appliance realizes the steam heating function, the first pump body can be turned on to operate at a first power, so that the liquid in the first containing box is transported to the steam generator at a first flow rate, and then the liquid is converted into steam and transported to the cooking cavity to realize the steam heating function.

[0047] Furthermore, when the food cleaning function of the cooking utensil needs to be realized, there is no need to adjust the operating power of the first pump body. The second pump body can be directly turned on to allow the liquid in the second containing box to be transported to the cooking cavity, and the second nozzle can be controlled to face the surface of the food to achieve cleaning of the surface of the food.

[0048] In any of the above technical solutions, the control method further includes: in response to a cooking cavity cleaning instruction, controlling the steam evaporator to stop running; controlling the liquid in the second containing box to be transported into the cooking cavity; controlling the second nozzle connected to the second containing box to rotate in the cooking cavity.

[0049] In this technical solution, when the cleaning function of the cooking cavity is realized, the first pump body can be stopped, and the liquid in the second containing box can be directly transported to the cooking cavity through the second nozzle through the operation of the second pump body. At the same time, the second nozzle is controlled to rotate in the cooking cavity to realize the cleaning of the circumferential inner wall of the cooking cavity.

[0050] In any of the above technical solutions, the control method further includes: obtaining a detection signal of a liquid level detection component in a recovery box of the cooking utensil; and controlling the liquid in the containing box to stop conveying when the detection signal is obtained.

[0051] In the technical solution, the cooking appliance further includes a recovery box and a liquid level detection member disposed in the recovery box. The recovery box can realize the recovery of waste water flowing out of the box. The liquid level detection member can realize the detection of the liquid level in the recovery box. When the detection signal of the liquid level detection member is detected, it indicates that there is a lot of liquid in the recovery box, and the user needs to clean the liquid in the recovery box in time to avoid the liquid in the recovery box from overflowing.

[0052] According to a third aspect of the present invention, a control device for a cooking appliance is proposed, comprising a control unit for controlling, in response to a cooking instruction, the liquid in a storage box to be delivered to a steam generator at a first flow rate; and controlling the operation of the steam generator to deliver steam to a cooking cavity; and in response to an instruction to clean food, controlling the liquid in the storage box to be delivered to the cooking cavity in the form of a vapor-liquid mixture.

[0053] The control device of the cooking appliance provided by the present invention can deliver steam or a vapor-liquid mixture into the cooking cavity to achieve steam heating of food in the cooking cavity or cleaning of the surface of the food.

[0054] Specifically, when the liquid in the container is delivered to the steam generator at a first flow rate, since the first flow rate is relatively small, during the operation of the steam generator, all the liquid delivered to the steam generator can be converted into steam, and then the steam generator delivers the converted steam to the cooking cavity to achieve steam heating of the food in the cooking cavity.

[0079] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present invention and the features in the embodiments can be combined with each other without conflict.

[0080] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0081] Refer to the following Figures 1 to 11 The cooking appliance and its control method, control device and readable storage medium provided according to some embodiments of the present invention are described.

[0082] The present invention provides a cooking device 100, such as Figure 1 and Figure 2 As shown, it includes a box body 102, and the box body 102 includes a cooking cavity 104; it also includes a containing box 106 and a steam valve artifact, wherein the containing box 106 is used to contain liquid; the inlet of the steam generator 108 is connected to the containing box 106, and the outlet of the steam generator 108 is connected to the cooking cavity 104 of the cooking utensil 100; further, the liquid in the containing box 106 can be delivered to the steam generator 108 at a first flow rate, so that the steam generator 108 can deliver steam to the cooking cavity 104, and the liquid in the containing box 106 can also be delivered to the steam generator 108 at a second flow rate, so that the steam generator 108 can deliver a vapor-liquid mixture to the cooking cavity 104, and the first flow rate is less than the second flow rate.

[0083] The cooking device 100 provided by the present invention includes a housing 102, which includes a cooking cavity 104. The cooking cavity 104 is used to place food, so that the food can be cooked in the cooking cavity 104. Specifically, a tray can be provided in the housing 102, so that the food can be placed on the tray for heating.

[0084] Furthermore, the cooking appliance 100 also includes a holding box 106 and a steam generator 108, wherein the holding box 106 is used to hold liquid, specifically water. The steam generator 108 is connected to the holding box 106, so that the liquid in the holding box 106 can be transported to the steam generator 108. Furthermore, during the operation of the steam generator 108, the liquid transported to the steam generator 108 can be evaporated, thereby converting the liquid into steam. Furthermore, the outlet of the steam generator 108 is connected to the cooking cavity 104, and after converting the liquid into steam, the steam generator 108 can finally transport the converted steam into the cooking cavity 104, so as to achieve steam heating of the food in the cooking cavity 104.

[0085] Furthermore, the liquid in the containing box 106 can be transported to the steam generator 108 at a first flow rate and a second flow rate, respectively, wherein the first flow rate is smaller than the second flow rate.

[0086] Specifically, when the liquid in the holding box 106 is delivered to the steam generator 108 at a first flow rate, since the first flow rate is relatively small, during the operation of the steam generator 108, all the liquid delivered to the steam generator 108 can be converted into steam, and then the steam generator 108 delivers the converted steam to the cooking cavity 104 to steam-heat the food in the cooking cavity 104. That is, when the liquid in the holding box 106 is delivered to the steam generator 108 at the first flow rate, it corresponds to the steam heating function of the cooking appliance 100.

[0087] When the liquid in the holding box 106 is delivered to the steam generator 108 at the second flow rate, the second flow rate is larger than the first flow rate. Therefore, during the operation of the steam generator 108, a part of the liquid delivered to the steam generator 108 can be converted into steam. Specifically, the steam generator 108 can convert 70% to 90% of the liquid into steam, and the other part still exists in the form of liquid. Then, the steam generator 108 can deliver the vapor-liquid mixture to the cooking cavity 104, so that the surface of the food can be rinsed with liquid while the food in the cooking cavity 104 is steam-heated, so as to rinse off the starch, grease, purine, salt and other components precipitated on the surface of the food during the heating process, thereby further improving the cooking effect of the food. That is, when the liquid in the holding box 106 is delivered to the steam generator 108 at the second flow rate, it corresponds to the food cleaning function of the cooking utensil 100. It can be understood that when the liquid in the holding box 106 is delivered to the steam generator 108 at a second flow rate, the outlet of the steam generator 108 can be controlled to be directed toward the surface of the food, so as to ensure that the liquid in the steam-liquid mixture output by the steam generator 108 can be sprayed onto the surface of the food, so as to rinse the substances precipitated on the surface of the food.

[0088] Specifically, during the cooking process, the user can first select the steam heating function of the cooking appliance 100. During the steam heating process, the starch, oil, purine, salt and other components in the food gradually precipitate to the surface of the food. After the steam heating lasts for a certain period of time, the user can adjust the cooking appliance 100 to perform the food cleaning function, and rinse off the substances precipitated on the surface of the food by outputting a vapor-liquid mixture. After the rinsing lasts for a certain period of time, the user can set the cooking appliance 100 to the steam heating function again, thereby completing the steam heating process of the food.

[0089] The cooking utensil 100 provided by the present invention controls the liquid in the holding box 106 of the cooking utensil 100 to be transported to the steam generator 108 at a first flow rate and a second flow rate, respectively, so that the cooking utensil 100 can respectively realize the steam heating function and the food cleaning function. Specifically, when the liquid in the holding box 106 is transported to the steam generator 108 at a first flow rate, the steam generator 108 converts all the liquid into steam to realize the steam heating function of the cooking utensil 100. When the liquid in the holding box 106 is transported to the steam generator 108 at a second flow rate, the steam generator 108 converts part of the liquid into steam, thereby realizing the transport of a vapor-liquid mixture to the surface of the food, so as to realize the cleaning of the food.

[0090] In the above embodiment, further, Figure 1 As shown, the cooking appliance 100 further includes a first spray head 110 , which is disposed in the cooking cavity 104 , an inlet of the first spray head 110 is connected to an outlet of the steam generator 108 , and the first spray head 110 can rotate in the cooking cavity 104 .

[0091] In this embodiment, the cooking appliance 100 may further be provided with a first nozzle 110. Specifically, the first nozzle 110 is provided in the cooking cavity 104, and the inlet of the first nozzle 110 is connected to the outlet of the steam generator 108. During the operation of the steam generator 108, the generated steam or the vapor-liquid mixture can be delivered to the cooking cavity 104 through the nozzle. In addition, during the process of delivering the vapor-liquid mixture to the cooking cavity 104, the angle of the first nozzle 110 can be adjusted so that the outlet of the first nozzle 110 faces the surface of the food in the cooking cavity 104, so as to ensure that the vapor-liquid mixture can be sprayed on the surface of the food, and ensure the cleaning effect of the precipitates on the surface of the food.

[0092] Furthermore, the cooking device 100 can also realize the function of cleaning the cooking cavity 104. Specifically, when realizing the function of cleaning the cooking cavity 104 of the cooking device 100, the steam generator 108 can be turned off, and the liquid in the containing box 106 is controlled to be transported to the steam generator 108 at a third flow rate. At this time, the steam generator 108 is not turned on, so the liquid will not be converted into steam, but directly transported to the cooking cavity 104 in a liquid state through the first nozzle 110, thereby realizing the cleaning of the cooking cavity 104. Furthermore, during the cleaning process, the first nozzle 110 can be controlled to rotate in the cooking cavity 104, so as to spray the liquid to the circumferential side wall in the cooking cavity 104, thereby improving the cleaning effect of the cooking cavity 104.

[0093] In any of the above embodiments, further, the containing box 106 includes a first containing box, and the cooking appliance 100 also includes: a first pump body 112, the inlet of the first pump body 112 is connected to the first containing box, and the outlet of the first pump body 112 is connected to the steam generator, wherein, when the first pump body 112 operates at a first power, the liquid in the first containing box can be delivered to the steam generator 108 at a first flow rate, and when the first pump body 112 operates at a second power, the liquid in the first containing box can be delivered to the steam generator 108 at a second flow rate.

[0094] In this embodiment, the cooking appliance 100 may further include a first pump body 112, through which the liquid in the containing box 106 may be driven, and then the liquid may be transported to the steam generator 108. Specifically, Fig. 9 and Fig.11 As shown, the first pump body 112 can be a water pump, and the containing box 106 can include a first containing box. When the water pump operates at a first power W1, it can drive the liquid in the first containing box to be transported to the steam generator 108 at a first flow rate Q1, thereby realizing the steam heating function of the cooking appliance 100.

[0095] Accordingly, when the water pump is operated at the second power W2, the liquid in the first containing box can be driven to be transported to the steam generator 108 at the second flow rate Q2. The steam generator 108 can then convert part of the liquid into steam and transport the vapor-liquid mixture into the cooking cavity 104 to clean the surface of the food in the cooking cavity 104. It can be understood that the first power W1 is less than the second power W2, and accordingly, the first flow rate Q1 is less than the second flow rate Q2.

[0096] Furthermore, when the cleaning function of the cooking cavity 104 is realized, the steam generator 108 is stopped first, and the water pump is controlled to run at the third power W3, so that the liquid in the first containing box can be delivered to the steam generator 108 at the third flow rate Q3, and then delivered to the cooking cavity 104 through the first nozzle 110, and the first nozzle 110 is controlled to rotate to realize the cleaning of the circumferential side wall in the cooking cavity 104. It can be understood that the third power W3 of the water pump is greater than the second power W2 and the first power W1, and accordingly, the third flow rate Q3 is greater than the second flow rate Q2 and the first flow rate Q1.

[0097] Furthermore, if Fig.10As shown, the containing box 106 includes a second containing box, and the cooking utensil 100 also includes: a second pump body, the inlet of the second pump body is connected with the second containing box; a second nozzle, arranged in the cooking cavity 104, the inlet of the second nozzle is connected with the outlet of the second pump body, and the second nozzle can rotate in the cooking cavity 104; wherein, the second pump body is used to transport the liquid in the second containing box to the cooking cavity 104 through the second nozzle.

[0098] Specifically, the containing box 106 may further include a second containing box, that is, the cooking utensil 100 includes a first containing box and a second containing box. Further, the cooking utensil 100 further includes a second pump body and a second nozzle, the inlet of the second pump body is connected to the second containing box, the second nozzle is connected to the outlet of the second pump body, and the second nozzle is arranged in the cooking cavity 104. That is, the liquid in the first containing box of the cooking utensil 100 can be transported to the cooking cavity 104 through the steam generator 108, and the liquid in the second containing box does not need to pass through the steam generator 108, and can be directly transported to the cooking cavity 104 through the second nozzle under the drive of the second pump body.

[0099] Specifically, when the cooking appliance 100 realizes the steam heating function, the first pump body 112 can be turned on to run at the first power W1, so that the liquid in the first containing box is transported to the steam generator 108 at the first flow rate Q1, and then the liquid is converted into steam and transported to the cooking cavity 104 to realize the steam heating function.

[0100] Furthermore, when the food cleaning function of the cooking utensil 100 needs to be realized, there is no need to adjust the operating power of the first pump body 112. The second pump body can be directly turned on to allow the liquid in the second containing box to be transported to the cooking cavity 104, and the second nozzle can be controlled to face the surface of the food to achieve cleaning of the surface of the food.

[0101] By setting up the second containing box and the second pump body, the steam delivery part can be separated from the liquid delivery part to ensure the delivery amount of steam and liquid, avoid mutual influence between steam delivery and liquid delivery, and thus ensure the heating and cleaning effects of the ingredients in the cooking cavity 104.

[0102] Furthermore, when the cleaning function of the cooking cavity 104 is to be realized, the operation of the first pump body 112 can be stopped, and the liquid in the second containing box can be directly transported to the cooking cavity 104 through the second nozzle through the operation of the second pump body, and the second nozzle can be controlled to rotate in the cooking cavity 104 to realize the cleaning of the circumferential inner wall of the cooking cavity 104.

[0103] In any of the above embodiments, further, Figure 1As shown, the cooking appliance 100 further includes: a recovery box 114 disposed at the bottom of the housing 102 . The recovery box 114 is connected to the cooking cavity 104 and is used to recover liquid flowing out of the cooking cavity 104 .

[0104] In this embodiment, a recovery box 114 may be provided at the bottom of the housing 102, and the recovery box 114 is connected to the cooking cavity 104. Specifically, a through hole may be provided on the bottom wall of the housing 102, and the through hole may be opposite to the opening of the recovery box 114, so that the cooking cavity 104 is connected to the recovery box 114. During cooking or cleaning, the liquid inside the cooking cavity can flow to the bottom of the cooking cavity 104 under gravity, and flow into the recovery box 114 through the through hole at the bottom of the housing 102, so as to recover the waste water and ensure the cleanliness of the cooking device 100 during use.

[0105] Furthermore, the cooking appliance 100 further includes: a liquid level detection element, which is disposed in the recovery box 114 and is used to detect the liquid level of the liquid in the recovery box 114 .

[0106] Specifically, by providing a liquid level detection component in the recovery box 114, the liquid level in the recovery box 114 can be detected in real time. When the liquid level in the recovery box 114 reaches a preset height, it indicates that there is a lot of liquid in the recovery box 114. The user needs to clean the liquid in the recovery box 114 in time to avoid overflow of the liquid in the recovery box 114.

[0107] According to a second aspect of the present invention, Figure 3 As shown, a control method for a cooking appliance is proposed, which is used for the cooking appliance of any one of the above technical solutions, and the control method includes:

[0108] S302, in response to a cooking instruction, controlling the liquid in the container to be delivered to the steam generator at a first flow rate;

[0109] S304, controlling the steam generator to operate so as to deliver steam into the cooking cavity;

[0110] S306, in response to the food cleaning instruction, controlling the liquid in the containing box to be delivered to the cooking cavity in the form of a vapor-liquid mixture.

[0111] The control method of the cooking appliance provided by the present invention can deliver steam or a vapor-liquid mixture into the cooking cavity to achieve steam heating of food in the cooking cavity or cleaning of the surface of the food.

[0112] Specifically, when the liquid in the container is delivered to the steam generator at a first flow rate Q1, since the first flow rate Q1 is relatively small, during the operation of the steam generator, all the liquid delivered to the steam generator can be converted into steam, and then the steam generator delivers the converted steam to the cooking cavity to achieve steam heating of the food in the cooking cavity. That is, when the liquid in the container is delivered to the steam generator at the first flow rate Q1, it corresponds to the steam heating function of the cooking appliance.

[0113] Furthermore, when the surface of the food needs to be cleaned, a food cleaning instruction can be input to transport the liquid in the holding box into the cooking cavity and spray it onto the surface of the food to clean the surface of the food.

[0114] In actual operation, the user can first select the steam heating function of the cooking utensil, that is, input the cooking instructions. During the steam heating process, the starch, oil, purine, salt and other components inside the food gradually precipitate to the surface of the food. After the steam heating lasts for a certain period of time, the user can adjust the cooking utensil to perform the food cleaning function, that is, input the food cleaning quality, so as to output the vapor-liquid mixture to rinse off the substances precipitated on the surface of the food. After the rinsing lasts for a certain period of time, the user can re-set the cooking utensil to the steam heating function to complete the steam heating process of the food.

[0115] According to one embodiment of the present invention, Figure 4 As shown, a control method for a cooking appliance is proposed, comprising:

[0116] S402, in response to a cooking instruction, controlling the liquid in the container to be delivered to the steam generator at a first flow rate;

[0119] S408, controlling the steam generator to operate so as to deliver the steam-liquid mixture into the cooking cavity.

[0120] In this embodiment, when it is necessary to clean the surface of the food in the cooking cavity, the liquid in the holding box can be controlled to be transported to the steam generator at a second flow rate Q2. The second flow rate Q2 is larger than the first flow rate Q1. Therefore, during the operation of the steam generator, a part of the liquid transported to the steam generator can be converted into steam. Specifically, the steam generator can convert 70% to 90% of the liquid into steam, and the other part still exists in the form of liquid. Then, the steam generator can transport the vapor-liquid mixture into the cooking cavity, so that the surface of the food can be rinsed with liquid while the food in the cooking cavity is steam-heated, so as to rinse off the starch, grease, purine, salt and other components precipitated on the surface of the food during the heating process, thereby further improving the cooking effect of the food. That is, when the liquid in the holding box is transported to the steam generator at the second flow rate Q2, it corresponds to the food cleaning function of the cooking utensil. It can be understood that when the liquid in the container is delivered to the steam generator at the second flow rate Q2, the outlet of the steam generator can be controlled to face the surface of the food to ensure that the liquid in the steam-liquid mixture output by the steam generator can be sprayed onto the surface of the food, so as to rinse the substances precipitated on the surface of the food.

[0128] S514, controlling the first nozzle connected to the steam generator to rotate in the cooking cavity.

[0129] In this embodiment, the cooking appliance can also realize the cooking cavity cleaning function. Specifically, in response to the cooking cavity cleaning instruction of the cooking appliance, the steam generator can be turned off, and the liquid in the containing box is controlled to be delivered to the steam generator at a third flow rate Q3. At this time, the steam generator is not turned on, so the liquid will not be converted into steam, but directly delivered to the cooking cavity in a liquid state through the first nozzle, thereby realizing the cleaning of the cooking cavity. Furthermore, during the cleaning process, the first nozzle can be controlled to rotate in the cooking cavity, so as to spray the liquid onto the circumferential side wall of the cooking cavity, thereby improving the cleaning effect of the cooking cavity.

[0130] According to one embodiment of the present invention, Figure 6 As shown, a control method for a cooking appliance is proposed, comprising:

[0153] The control device of the cooking appliance provided by the present invention can deliver steam or a vapor-liquid mixture into the cooking cavity to achieve steam heating of food in the cooking cavity or cleaning of the surface of the food.

[0154] Specifically, when the liquid in the container is delivered to the steam generator at a first flow rate Q1, since the first flow rate Q1 is relatively small, during the operation of the steam generator, all the liquid delivered to the steam generator can be converted into steam, and then the steam generator delivers the converted steam to the cooking cavity to achieve steam heating of the food in the cooking cavity.
