Description

Technical Field

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

[0002] Currently, electric steamers sold on the market are unable to accurately match the cooking time according to the type and amount of ingredients. Users need to set an approximate cooking time by themselves. Therefore, it is easy to have the phenomenon that the food is undercooked or overcooked after cooking, which not only seriously affects the taste and deliciousness of the food, but also brings a bad user experience to users. Summary of the Invention

[0003] The present invention aims to at least solve or improve the technical problem in the prior art that the cooking time of a cooking appliance cannot be accurately matched.

[0004] To this end, a first aspect embodiment of the present invention proposes a control method for a cooking appliance.

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

[0006] A third aspect embodiment of the present invention proposes an electronic device.

[0007] A fourth aspect embodiment of the present invention proposes a readable storage medium.

[0008] A fifth aspect embodiment of the present invention proposes a cooking appliance.

[0009] A sixth aspect embodiment of the present invention proposes a cooking appliance.

[0010] In view of this, according to the first aspect of the present invention, the present invention proposes a control method for a cooking appliance, including: obtaining the temperature rise situation in the cooking cavity; determining the weight of the ingredients according to the temperature rise situation and the type of ingredients in the cooking cavity; determining the remaining cooking time according to the weight.

[0011] The control method for a cooking appliance proposed by the present invention includes obtaining the temperature rise situation in the cooking cavity of the cooking appliance, determining the weight of the ingredients according to the temperature rise situation and the type of ingredients in the cooking cavity, and determining the remaining cooking time required for cooking according to the weight of the ingredients.

[0012] Among them, the type of ingredients can be input into the cooking appliance by the user, or can be automatically recognized by the cooking appliance through components such as a camera or a radar.

[0013] Moreover, when the temperature rises in the cooking cavity, the temperature rise is affected by the weight of the food ingredients. Therefore, the temperature rise in the cooking cavity can objectively reflect the weight of the food ingredients. Also, different weights of food ingredients require different cooking times. Therefore, the remaining cooking time can be determined based on the weight of the food ingredients, enabling the cooking appliance to accurately match the cooking time and improve the cooking effect of the cooking appliance.

[0014] In addition, according to the control method of the cooking appliance provided by the above technical solution of the present invention, the following additional technical features may also be included:

[0015] In some embodiments, optionally, the step of determining the weight of the food ingredients based on the temperature rise and the type of food ingredients in the cooking cavity includes: determining the weight coefficient of the food ingredients according to the type; and determining the weight according to the weight coefficient and the temperature rise.

[0016] In this embodiment, the step of determining the type of food ingredients based on the temperature rise and the type of food ingredients in the cooking cavity includes: determining the weight coefficient of the food ingredients according to the type of the food ingredients, and determining the weight of the food ingredients according to the corresponding weight coefficient of the food ingredients and the temperature rise in the cooking cavity. Among them, the weight coefficient of the food ingredients needs to be determined through experiments for different cooking appliances. Different cooking appliances have different powers and different volumes of the cooking cavity. Therefore, their weight coefficients are also different. After determining the weight coefficient through experiments, it is pre-stored in the cooking appliance or in the server, and the cooking appliance can obtain the weight coefficient locally or online.

[0017] Moreover, since the weight coefficient is fully matched to the current cooking appliance, determining the weight according to the weight coefficient can improve the accuracy of weight determination.

[0018] Each type of food ingredient is matched with a weight coefficient.

[0019] In some embodiments, optionally, the step of determining the remaining cooking time based on the weight includes: obtaining the remaining time coefficient of the cooking appliance; and determining the remaining cooking time according to the remaining time coefficient and the weight.

[0020] In this embodiment, the step of determining the remaining cooking time based on the weight includes: obtaining the remaining time coefficient of the cooking appliance, and determining the remaining cooking time according to the remaining time coefficient and the weight of the food ingredients. Among them, the remaining time coefficient needs to be determined through experiments for different cooking appliances. Different cooking appliances have different powers and different volumes of the cooking cavity. Therefore, their remaining time coefficients are also different. After determining the remaining time coefficient through experiments, it is pre-stored in the cooking appliance or in the server, and the cooking appliance can obtain the remaining time coefficient locally or online.

[0021] Moreover, since the remaining time coefficient exactly matches the current cooking appliance, determining the remaining cooking time according to the remaining time coefficient can improve the accuracy of determining the remaining cooking time.

[0022] In some embodiments, optionally, it further includes: obtaining the water volume in the cooking appliance; controlling the working state of the cooking appliance according to the water volume and the remaining cooking time.

[0023] In this embodiment, the control method of the cooking appliance further includes: after determining the remaining cooking time, obtaining the water volume in the cooking appliance, and controlling the working state of the cooking appliance according to the water volume in the cooking appliance and the remaining cooking time. After the remaining cooking time is determined, it is possible to determine whether the current water volume in the cooking appliance is sufficient to support the entire cooking process. Thus, the working state of the cooking appliance can be controlled according to the remaining cooking time and the water volume in the cooking appliance, thereby improving the cooking effect of the cooking appliance.

[0024] In some embodiments, optionally, the step of controlling the working state of the cooking appliance according to the water volume and the remaining cooking time includes: when the water volume is less than the first threshold, controlling the cooking appliance to issue a water addition prompt; when the water volume is greater than or equal to the first threshold, controlling the cooking appliance to continue cooking; wherein, the first threshold is determined according to the remaining cooking time.

[0025] In this embodiment, the step of controlling the working state of the cooking appliance according to the water volume and the remaining cooking time includes: when the water volume is less than the first threshold, it indicates that the current water volume is not sufficient to support the cooking process of the cooking appliance. Therefore, it is necessary to control the cooking appliance to issue a heating prompt, thereby improving the cooking effect of the cooking appliance and reducing the occurrence of situations such as dry burning or inability to complete cooking of the cooking appliance. The water addition prompt can be issued through an indicator light, voice, or display screen, etc. Currently, the prompt can also be sent to a user-specified terminal through the network, such as a mobile phone, tablet computer, TV, computer, or speaker, etc.

[0026] When the water volume is greater than or equal to the first threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance. Therefore, it is only necessary to control the cooking appliance to continue cooking, and the cooking appliance can complete the cooking of the ingredients by continuing to cook for the remaining cooking time.

[0027] Wherein, the first threshold is a set value, and it can be based on the water volume required for the cooking appliance to cook for the remaining time at the first power. The first power can be the lowest operating power of the cooking appliance and other set powers. That is, the first threshold is used as the minimum water volume for completing cooking. Therefore, the working state of the cooking appliance can be determined based on the first threshold.

[0028] In some embodiments, optionally, when the water volume is greater than or equal to the first threshold, the steps of controlling the cooking appliance to continue cooking include: when the water volume is greater than or equal to the first threshold and less than the second threshold, controlling the cooking appliance to reduce the heating power; when the water volume is greater than or equal to the second threshold and less than the third threshold, controlling the cooking appliance to maintain the current heating power; when the water volume is greater than or equal to the third threshold, controlling the cooking appliance to increase the heating power; wherein, the second threshold is greater than the first threshold, and the third threshold is greater than the second threshold.

[0029] In this embodiment, the steps of controlling the cooking appliance to continue cooking include: when the water volume is greater than or equal to the first threshold and less than the second threshold, controlling the cooking appliance to reduce the heating power and continue cooking, that is, if the current water volume is not sufficient to support the cooking appliance to continue cooking at the current working state, the cooking appliance is controlled to reduce the heating power, so as to ensure that the cooking can be completed smoothly.

[0030] When the water volume is greater than or equal to the second threshold and less than the third threshold, controlling the cooking appliance to maintain the current heating power and continue cooking, that is, if the current water volume can only support the cooking appliance to continue working at the current heating power, the cooking appliance is controlled to continue running at the current heating power, so as to ensure that the cooking can be completed smoothly and, as much as possible, shorten the cooking time.

[0031] When the water volume is greater than or equal to the third threshold, controlling the cooking appliance to increase the heating power and continue cooking, that is, if the current water volume is sufficient to support the cooking appliance to increase the heating power and continue running, the cooking appliance is controlled to increase the heating power, so as to further shorten the cooking time.

[0032] Wherein, the second threshold is greater than the first threshold. Specifically, the second threshold is determined according to the heating power of the current cooking appliance. The heating power of the current cooking appliance can be the second power, and the second power is greater than the first power.

[0033] The third threshold is greater than the second threshold. Specifically, the third threshold is determined according to the third power of the cooking appliance. The third power is greater than the second power, and the third power can be the maximum heating power of the cooking appliance, etc.

[0034] Thus, according to the water volume of the cooking appliance, the cooking time is dynamically adjusted to improve the cooking effect of the cooking appliance.

[0035] In some embodiments, optionally, the steps of obtaining the temperature rise situation in the cooking cavity include: controlling the cooking appliance to work at the target heating power, obtaining the temperature in the cooking cavity; after the temperature reaches the target temperature threshold for the target duration, determining the change time for the temperature to reach the target temperature threshold from the initial temperature; and determining the temperature rise situation according to the initial temperature, the target temperature threshold and the change time.

[0036] In this embodiment, the steps of obtaining the temperature rise in the cooking cavity include: when the cooking appliance starts cooking, controlling the cooking appliance to operate at a target heating power. This stage can be defined as the temperature rise stage. During this stage, the temperature in the cooking cavity is obtained. And when the temperature reaches the target temperature threshold for the target duration, it is determined that the target temperature threshold is the cooking temperature set by the user. Then, the change time from the initial temperature to the target temperature threshold in the cooking cavity at the start of cooking is calculated. The temperature rise situation is determined based on the initial temperature, the target temperature threshold, and the change time.

[0037] Among them, the initial temperature, the target temperature threshold, and the change time fully reflect the temperature change process in the cooking appliance, thereby ensuring the accuracy of determining the temperature rise situation.

[0038] According to the second aspect of the present invention, a control device for a cooking appliance is proposed, including: a first acquisition module for obtaining the temperature rise situation in the cooking cavity; a first determination module for determining the weight of the ingredients according to the temperature rise situation and the type of ingredients in the cooking cavity; a second determination module for determining the remaining cooking time according to the weight.

[0039] The control device for the cooking appliance proposed by the present invention includes obtaining the temperature rise situation in the cooking cavity of the cooking appliance, determining the weight of the ingredients according to the temperature rise situation and the type of ingredients in the cooking cavity, and determining the remaining cooking time required for cooking according to the weight of the ingredients.

[0040] Among them, the type of ingredients can be input by the user into the cooking appliance, or can be self-identified by the cooking appliance through components such as a camera or radar.

[0041] Moreover, when the temperature rises in the cooking cavity, its temperature rise situation will be affected by the weight of the ingredients. Therefore, the temperature rise situation in the cooking cavity can objectively reflect the weight of the ingredients. And different weights of ingredients require different cooking times. Therefore, the remaining cooking time can be determined according to the weight of the ingredients, so that the cooking appliance can accurately match the cooking time and improve the cooking effect of the cooking appliance.

[0042] According to the third aspect of the present invention, an electronic device is proposed, including a processor, a memory, and a program or instruction stored in the memory and executable on the processor. When the program or instruction is executed by the processor, it implements the control method of the cooking appliance as proposed in the first aspect.

[0043] The electronic device proposed by the present invention includes a processor, a memory, and a program or instruction stored on the memory and executable on the processor. Since the program or instruction, when executed by the processor, implements the control method of the cooking appliance proposed in the first aspect, the electronic device proposed by the present invention has all the beneficial effects of the control method of the cooking appliance proposed in the first aspect, which will not be elaborated one by one here.

[0044] According to the fourth aspect of the present invention, a readable storage medium is proposed. A program or instruction is stored on the readable storage medium, and when the program or instruction is executed by a processor, the steps of the control method of the cooking appliance proposed in the first aspect are implemented.

[0045] For the readable storage medium proposed by the present invention, a program or instruction is stored on the readable storage medium. Since the program or instruction, when executed by a processor, implements the control method of the cooking appliance proposed in the first aspect, the readable storage medium proposed by the present invention has all the beneficial effects of the control method of the cooking appliance proposed in the first aspect, which will not be elaborated one by one here.

[0046] According to the fifth aspect of the present invention, a cooking appliance is proposed, including: the control device of the cooking appliance proposed in the second aspect; or the electronic device proposed in the third aspect; or the readable storage medium proposed in the fourth aspect.

[0047] For the cooking appliance proposed by the present invention, since it includes the control device of the cooking appliance proposed in the second aspect; or the electronic device proposed in the third aspect; or the readable storage medium proposed in the fourth aspect, the cooking appliance proposed by the present invention has all the beneficial effects of the control device of the cooking appliance proposed in the second aspect; or the electronic device proposed in the third aspect; or the readable storage medium proposed in the fourth aspect, which will not be elaborated one by one here.

[0048] According to the sixth aspect of the present invention, a cooking appliance is proposed, including: a steam generating device; a steamer disposed on the steam generating device, the steamer including a cooking chamber; a temperature detection component disposed on the steam generating device for detecting the temperature in the cooking chamber; a controller disposed on the steam generating device and electrically connected to the temperature detection component and the steam generating device; wherein, the controller is configured to, during the cooking process, obtain the temperature rise situation in the cooking chamber according to the temperature detection component; determine the weight of the food ingredients in the cooking chamber according to the temperature rise situation and the types of food ingredients in the cooking chamber; and determine the remaining cooking time of the steam generating device according to the weight.

[0049] The cooking appliance proposed by the present invention includes a steam generating device, a steamer basket, and a temperature detection component. The steamer basket is arranged on the steam generating device. The steamer basket includes a cooking cavity where food ingredients can be placed. The steam generated by the steam generating device can cook the food ingredients in the steamer basket. The temperature detection component can detect the temperature in the cooking cavity of the steamer basket. The controller is electrically connected to the temperature detection component and the steam generating device. Thus, the controller can obtain the temperature rise situation in the cooking cavity of the cooking appliance through the temperature detection component, determine the weight of the food ingredients according to the temperature rise situation and the type of food ingredients in the cooking cavity, and determine the remaining cooking time required for cooking according to the weight of the food ingredients.

[0050] Among them, the type of food ingredients can be input by the user into the cooking appliance, or can be recognized by the cooking appliance itself through components such as a camera or radar.

[0051] Moreover, when the temperature in the cooking cavity rises, its temperature rise situation will be affected by the weight of the food ingredients. Therefore, the temperature rise situation in the cooking cavity can objectively reflect the weight of the food ingredients. And, the required cooking time for food ingredients of different weights is also different. Therefore, the remaining cooking time can be determined according to the weight of the food ingredients, so that the cooking appliance can accurately match the cooking time and improve the cooking effect of the cooking appliance.

[0052] In some embodiments, optionally, the steam generating device includes a heating element and a heating cavity, and the heating element is used to heat the heating cavity.

[0053] In this embodiment, the steam generating device includes a heating element and a heating cavity. The heating element is used to heat the heating cavity. Thus, when there is water in the heating cavity, the water in the heating cavity can be heated to generate steam, and the steam enters the cooking cavity to realize the cooking of the food ingredients.

[0054] In some embodiments, optionally, the heating cavity includes a first heating cavity and a second heating cavity, the heating element includes a first heating element and a second heating element. The first heating element is used to heat the inside of the first heating cavity, and the second heating element is used to heat the inside of the second heating cavity. The controller is electrically connected to the first heating element and the second heating element.

[0055] In this embodiment, the heating cavity includes a first heating cavity and a second heating cavity, the heating element includes a first heating element and a second heating element. The first heating element is used to heat the inside of the first heating cavity, and the second heating element is used to heat the inside of the second heating cavity. The first heating cavity and the second heating cavity can provide steam for the cooking cavity simultaneously, and the first heating cavity and the second heating cavity can also provide steam for the cooking cavity separately.

[0056] Thus, the two heating elements and the two heating cavities can enable the cooking appliance to have a larger adjustment range of heating power.

[0057] In some embodiments, optionally, the cooking chamber includes a first chamber and a second chamber. The first chamber includes a first state in communication with the first heating chamber and a second state in communication with both the first heating chamber and the second heating chamber. The second chamber includes a third state in communication with the second heating chamber and a fourth state in communication with both the first heating chamber and the second heating chamber.

[0058] In this embodiment, the cooking chamber includes a first chamber and a second chamber. In the case of the first state of the first chamber, the first chamber is in communication with the first heating chamber, that is, steam is provided to the first chamber by the first heating chamber. In the case of the second state of the first chamber, the first chamber is in communication with both the first heating chamber and the second heating chamber, that is, steam is provided to the first chamber jointly by the first heating chamber and the second heating chamber.

[0059] In the case of the third state of the second chamber, the second chamber is in communication with the second heating chamber, that is, steam is provided to the second chamber by the second heating chamber. In the case of the fourth state of the second chamber, the second chamber is in communication with both the first heating chamber and the second heating chamber, that is, steam is provided to the second chamber jointly by the first heating chamber and the second heating chamber.

[0060] In some embodiments, optionally, when the cooking appliance is in the temperature rise stage, the controller controls the first heating element and the second heating element to work simultaneously; the controller controls the working states of the first heating element and the second heating element according to the remaining cooking time and the amount of water in the cooking appliance.

[0061] In this embodiment, in the temperature rise stage of the cooking appliance, that is, the initial stage when the cooking appliance starts cooking, the first heating element and the second heating element are controlled to work simultaneously, which increases the amount of steam provided to the cooking chamber, improves the temperature rise speed of the cooking chamber, and improves the cooking speed of the cooking appliance. Moreover, rapid heating can quickly denature the surface of the ingredients, achieve the effect of locking water, and improve the taste of the ingredients, etc., that is, improve the cooking effect of the cooking appliance.

[0062] Moreover, after determining the remaining cooking time, the controller obtains the amount of water in the cooking appliance and controls the working states of the first heating element and the second heating element according to the amount of water in the cooking appliance and the remaining cooking time. After the remaining cooking time is determined, it can be determined whether the amount of water in the current cooking appliance is sufficient to support the entire cooking process, so that the working states of the first heating element and the second heating element can be controlled according to the remaining cooking time and the amount of water in the cooking appliance, thereby improving the cooking effect of the cooking appliance.

[0063] In some embodiments, optionally, when the water volume is greater than or equal to a fourth threshold and less than a fifth threshold, the controller controls one of the first heating element and the second heating element to turn off and the other to operate; when the water volume is greater than or equal to the fifth threshold and less than a sixth threshold, the controller controls the first heating element and the second heating element to maintain their current operating states; when the water volume is greater than or equal to the sixth threshold, the controller controls the first heating element and / or the second heating element to increase the heating power; wherein, the fifth threshold is greater than the fourth threshold, the sixth threshold is greater than the fifth threshold, and the fourth threshold is determined according to the remaining cooking time.

[0064] In this embodiment, when the water volume is greater than or equal to the fourth threshold and less than the fifth threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance. However, it is not sufficient to support the simultaneous operation of the two heating elements. Therefore, the controller controls one of the first heating element and the second heating element to turn off and the other to turn on.

[0065] Among them, the fourth threshold is a set value, which can be the water volume required for the cooking appliance to cook the remaining time using a single heating element. The fifth threshold is a set value, which can be the water volume required for the cooking appliance to cook the remaining time using two heating elements.

[0066] When the water volume is greater than or equal to the fifth threshold and less than the sixth threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance and is sufficient to support the simultaneous operation of the two heating elements. Therefore, the controller controls the first heating element and the second heating element to continue operating.

[0067] Among them, the sixth threshold is a set value, which can be the water volume required for the cooking appliance to cook the remaining time using two heating elements.

[0068] When the water volume is greater than the sixth threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance and is sufficient to support the two heating elements to operate simultaneously with a greater heating power. Therefore, the controller controls the first heating element and the second heating element to increase the heating power.

[0069] According to the above control logic, it is possible to ensure that the cooking time is shortened as much as possible when the cooking is completed.

[0070] In some embodiments, optionally, the temperature detection component is used to detect the temperature in the first cavity; or the temperature detection component includes a first temperature detection element and a second temperature detection element. The first temperature detection element is used to detect the temperature in the first cavity, and the second temperature detection element is used to detect the temperature in the second cavity. The controller is electrically connected to the first temperature detection element and the second temperature detection element.

[0071] In this embodiment, the temperature detection component is used to detect the temperature in the first cavity. That is, the temperature detection component reflects the temperatures of the first cavity and the second cavity through the first cavity.

[0072] Alternatively, the temperature detection component includes a first temperature detection piece and a second temperature detection piece. The first temperature detection piece is used to detect the temperature in the first cavity, and the second temperature detection piece is used to detect the temperature in the second cavity. The controller is electrically connected to the first temperature detection piece and the second temperature detection piece. That is, the first cavity and the second cavity are respectively based on the first temperature detection piece and the second temperature detection piece, improving the accuracy of obtaining the temperature in the cooking cavity.

Detailed implementation manners

[0086] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0087] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention may be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0088] Next, refer to Figures 1 to 9 to describe a control method for a cooking appliance, a control device for a cooking appliance, an electronic device, a readable storage medium, and a cooking appliance according to some embodiments of the present invention. Among them, Figure 8 the arrows in indicate the flow direction of the steam.

[0089] Figure 1 shows a flowchart of a control method for a cooking appliance provided by an embodiment of the present invention.

[0090] As Figure 1 shown, the specific process of the control method for a cooking appliance provided by an embodiment of the present invention is as follows:

[0091] Step 102: Obtain the temperature rise situation in the cooking cavity;

[0092] Step 104: Determine the weight of the food ingredients according to the temperature rise situation and the types of food ingredients in the cooking cavity;

[0093] Step 106: Determine the remaining cooking time according to the weight.

[0094] The control method of the cooking appliance provided by the present invention includes obtaining the temperature rise situation in the cooking cavity of the cooking appliance, determining the weight of the food material according to the temperature rise situation in the cooking cavity and the type of the food material in the cooking cavity, and determining the remaining cooking time required for cooking according to the weight of the food material.

[0095] Among them, the type of the food material can be input into the cooking appliance by the user, or can be automatically recognized by the cooking appliance through components such as a camera or a radar.

[0096] Moreover, when the temperature rises in the cooking cavity, its temperature rise situation will be affected by the weight of the food material. Therefore, the temperature rise situation in the cooking cavity can objectively reflect the weight of the food material. And, the required ripening time for food materials of different weights is also different. Therefore, the remaining cooking time can be determined according to the weight of the food material, so that the cooking appliance can accurately match the cooking time and improve the cooking effect of the cooking appliance.

[0097] In some embodiments, optionally, the step of determining the weight of the food material according to the temperature rise situation in the cooking cavity and the type of the food material in the cooking cavity includes: determining the weight coefficient of the food material according to the type of the food material; and determining the weight according to the weight coefficient and the temperature rise situation.

[0098] In this embodiment, the step of determining the type of the food material according to the temperature rise situation and the type of the food material in the cooking cavity includes: determining the weight coefficient of the food material according to the type of the food material, and determining the weight of the food material according to the corresponding weight coefficient of the food material and the temperature rise situation in the cooking cavity. Among them, the weight coefficient of the food material needs to be determined through experiments for different cooking appliances. Different cooking appliances have different powers and different volumes of the cooking cavity. Therefore, their weight coefficients are also different. After determining the weight coefficient through experiments, it is pre-stored in the cooking appliance or pre-stored in the server. The cooking appliance can obtain the weight coefficient locally or online.

[0099] Moreover, since the weight coefficient is completely matched with the current cooking appliance, determining the weight according to the weight coefficient can improve the accuracy of weight determination.

[0100] Among them, each type of food material is matched with a weight coefficient.

[0101] Specifically, the types of the food material can be seafood, vegetables and meat. For example: the types of the food material can be sea bass, yellow croaker, mandarin fish, scallop, shrimp, crab, potato, eggplant, Chinese cabbage, vermicelli, beef, chicken or pork, etc. Among them, each type can be matched with a separate weight coefficient, or all weights can be matched with a weight coefficient, or multiple types can be matched with a weight coefficient, etc.

[0102] In some embodiments, optionally, the step of determining the remaining cooking time according to the weight of the food ingredient includes: obtaining the remaining time coefficient of the cooking appliance; and determining the remaining cooking time of the cooking appliance according to the remaining time coefficient and the weight of the food ingredient.

[0103] In this embodiment, the step of determining the remaining cooking time according to the weight includes: obtaining the remaining time coefficient of the cooking appliance, and determining the remaining cooking time according to the remaining time coefficient and the weight of the food ingredient. The remaining time coefficient needs to be determined through experiments for different cooking appliances. Different cooking appliances have different powers and different volumes of the cooking cavity. Therefore, their remaining time coefficients are also different. After determining the remaining time coefficient through experiments, it is pre-stored in the cooking appliance or pre-stored in the server. The cooking appliance can obtain the remaining time coefficient locally or online.

[0104] Moreover, since the remaining time coefficient exactly matches the current cooking appliance, determining the remaining cooking time according to the remaining time coefficient can improve the accuracy of determining the remaining cooking time.

[0105] In some embodiments, optionally, it further includes: obtaining the water volume in the liquid storage cavity of the cooking appliance; and controlling the working state of the heating element of the cooking appliance according to the water volume in the liquid storage cavity and the remaining cooking time.

[0106] In this embodiment, the control method of the cooking appliance further includes: after determining the remaining cooking time, obtaining the water volume in the liquid storage cavity of the cooking appliance, and controlling the working state of the heating element of the cooking appliance according to the water volume in the cooking appliance and the remaining cooking time. After determining the remaining cooking time, it can be determined whether the water volume in the current cooking appliance is sufficient to support the entire cooking process, so that the working state of the cooking appliance can be controlled according to the remaining cooking time and the water volume in the cooking appliance, thereby improving the cooking effect of the cooking appliance.

[0107] In some embodiments, optionally, the step of controlling the working state of the cooking appliance according to the water volume and the remaining cooking time includes: when the water volume in the liquid storage cavity is less than the first threshold, controlling the cooking appliance to issue a water addition prompt; when the water volume is greater than or equal to the first threshold, controlling the heating element of the cooking appliance to continue cooking; wherein the first threshold is determined according to the remaining cooking time.

[0108] In this embodiment, the steps of controlling the working state of the heating element of the cooking appliance according to the water volume in the liquid storage cavity and the remaining cooking time include: when the water volume in the liquid storage cavity is less than the first threshold, it indicates that the current water volume is not sufficient to support the cooking process of the cooking appliance. Therefore, it is necessary to control the cooking appliance to issue a heating prompt, so as to improve the cooking effect of the cooking appliance and reduce the occurrence of the situation that the cooking appliance dries out or fails to complete cooking. Among them, the water addition prompt can be issued through an indicator light, voice, display screen, etc. Currently, the prompt can also be sent to the user-specified terminal through the network, such as: mobile phone, tablet computer, TV, computer, or speaker, etc.

[0109] When the water volume is greater than or equal to the first threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance. Therefore, it is only necessary to control the heating element of the cooking appliance to continue working, and the heating element continues to work for the remaining cooking time to complete the cooking of the ingredients.

[0110] Among them, the first threshold is a set value, and it can be based on the water volume required for the cooking appliance to cook for the remaining time at the first power. Among them, the first power can be the lowest operating power of the cooking appliance and other set powers, that is, the first threshold is used as the minimum water volume to complete cooking. Therefore, the working state of the cooking appliance can be determined based on the first threshold.

[0111] In some embodiments, optionally, the steps of controlling the heating element of the cooking appliance to continue cooking when the water volume in the liquid storage cavity is greater than or equal to the first threshold include: when the water volume in the liquid storage cavity is greater than or equal to the first threshold and less than the second threshold, control the heating element of the cooking appliance to reduce the heating power; when the water volume is greater than or equal to the second threshold and less than the third threshold, control the heating element of the cooking appliance to maintain the current heating power; when the water volume is greater than or equal to the third threshold, control the heating element of the cooking appliance to increase the heating power; among them, the second threshold is greater than the first threshold, and the third threshold is greater than the second threshold.

[0112] In this embodiment, the steps of controlling the heating element of the cooking appliance to continue cooking include: when the water volume is greater than or equal to the first threshold and less than the second threshold, control the heating element of the cooking appliance to reduce the heating power and continue cooking. That is, if the current water volume is not sufficient to support the heating element of the cooking appliance to continue cooking at the current heating power, then control the heating element of the cooking appliance to reduce the heating power, so as to ensure that the cooking can be completed smoothly.

[0113] When the water volume is greater than or equal to the second threshold and less than the third threshold, control the heating element of the cooking appliance to maintain the current heating power and continue cooking. That is, if the current water volume can only support the heating element of the cooking appliance to continue working at the current heating power, control the heating element of the cooking appliance to continue running at the current heating power, so as to ensure that the cooking can be completed smoothly and, as much as possible, shorten the cooking time.

[0114] When the water volume is greater than or equal to the third threshold, control the heating element of the cooking appliance to increase the heating power and continue cooking. That is, if the current water volume is sufficient to support the heating element of the cooking appliance to increase the heating power and continue running, control the heating element of the cooking appliance to increase the heating power, so as to further shorten the cooking time.

[0115] Among them, the second threshold is greater than the first threshold. Specifically, the second threshold is determined according to the current heating power of the cooking appliance. The current heating power of the cooking appliance can be the second power, and the second power is greater than the first power.

[0116] The third threshold is greater than the second threshold. Specifically, the third threshold is determined according to the third power of the cooking appliance. The third power is greater than the second power, and the third power can be the maximum heating power of the cooking appliance, etc.

[0117] Thus, according to the water volume in the liquid storage cavity of the cooking appliance, dynamically adjust the cooking time and improve the cooking effect of the cooking appliance.

[0118] In some embodiments, optionally, the step of obtaining the temperature rise situation in the cooking cavity includes: controlling the heating element of the cooking appliance to work at the target heating power, obtaining the temperature in the cooking cavity; after the temperature reaches the target temperature threshold for the target duration, determining the change time for the temperature to reach the target temperature threshold from the initial temperature; and determining the temperature rise situation according to the initial temperature, the target temperature threshold, and the change time.

[0119] In this embodiment, the step of obtaining the temperature rise situation in the cooking cavity includes: when the cooking appliance starts cooking, controlling the heating element of the cooking appliance to work at the target heating power. This stage can be defined as the heating-up stage. In this stage, obtain the temperature in the cooking cavity. And, after the temperature reaches the target temperature threshold for the target duration, it is determined that the target temperature threshold is the cooking temperature set by the user. Furthermore, calculate the change time for the temperature in the cooking cavity to reach the target temperature threshold from the initial temperature at the start of cooking, and determine the temperature rise situation according to the initial temperature, the target temperature threshold, and the change time.

[0120] Among them, the initial temperature, the target temperature threshold, and the change time fully reflect the temperature change process in the cooking appliance, thus ensuring the accuracy of determining the temperature rise situation.

[0121] Specifically, the temperature rise situation can be a temperature rise curve, t_remaining = s × m, m = c ÷ k, k = T1 ÷ t, that is, t_remaining = s × c × t ÷ T1.

[0122] Among them, t_remaining represents the remaining cooking time, s represents the remaining time coefficient, m represents the weight of the food ingredient, c represents the weight coefficient of the food ingredient, k represents the temperature rise curve of the food ingredient, that is, the temperature rise situation, t represents the time when the temperature of the cooking cavity reaches the target temperature threshold, and T1 represents the target temperature threshold.

[0123] As Figure 9 shown, the temperature rise situation is represented by a coordinate system. Among them, O is the origin, representing the initial temperature and the initial time, and T1 represents the target temperature threshold.

[0124] Among them, k1 = T1 ÷ t1, k2 = T1 ÷ t2, k3 = T1 ÷ t3.

[0125] k1, k2, and k3 respectively represent the temperature rise curves of food ingredients with different weights, and t1, t2, and t3 represent the times when the temperature of the cooking cavity reaches the target temperature threshold in the case of food ingredients with different weights.

[0126] m1 = c1 ÷ k1 = c1 × t1 ÷ T1, m2 = c2 ÷ k2 = c2 × t2 ÷ T1, m3 = c3 ÷ k3 = c3 × t3 ÷ T1.

[0127] m1, m2, and m3 represent the weights of different food ingredients, and c1, c2, and c3 represent the weight coefficients of different food ingredients. Among them, c1, c2, and c3 can be the same or different.

[0128] t_remaining1 = s1 × m1 = s1 × c1 × t1 ÷ T1, t_remaining2 = s2 × m2 = s2 × c2 × t2 ÷ T1, t_remaining3 = s3 × m3 = s3 × c3 × t3 ÷ T1.

[0129] t_remaining1, t_remaining2, and t_remaining3 represent the remaining cooking times corresponding to food ingredients with different weights, and s1, s2, and s3 represent the remaining time coefficients of different food ingredients. Among them, s1, s2, and s3 can be the same or different.

[0130] The control methods of the cooking appliance can be implemented in various different ways according to specific features and / or example applications. For example, these methods can be implemented through a combination of hardware, firmware, and / or software. For example, in 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 above functions, and / or combinations thereof.

[0131] As Figure 2 shown, according to the second aspect of the present invention, the present invention provides a control device 200 for a cooking appliance, comprising: a first acquisition module 202 for acquiring the temperature rise situation in the cooking cavity; a first determination module 204 for determining the weight of the food ingredients according to the temperature rise situation and the types of food ingredients in the cooking cavity; and a second determination module 206 for determining the remaining cooking time according to the weight.

[0132] The control device for a cooking appliance provided by the present invention includes acquiring the temperature rise situation in the cooking cavity of the cooking appliance, determining the weight of the food ingredients according to the temperature rise situation and the types of food ingredients in the cooking cavity, and determining the remaining cooking time required for cooking according to the weight of the food ingredients.

[0133] Among them, the types of food ingredients can be input by the user into the cooking appliance, or can be self-identified by the cooking appliance through components such as a camera or radar.

[0134] Moreover, when the temperature rises in the cooking cavity, its temperature rise situation will be affected by the weight of the food ingredients. Therefore, the temperature rise situation in the cooking cavity can objectively reflect the weight of the food ingredients, and moreover, the required cooking times for food ingredients of different weights are also different. Therefore, the remaining cooking time can be determined according to the weight of the food ingredients, so that the cooking appliance can accurately match the cooking time and improve the cooking effect of the cooking appliance.

[0135] In some embodiments, optionally, the first determination module includes: a first determination sub-module for determining the weight coefficient of the food ingredients according to the type; and a second determination sub-module for determining the weight according to the weight coefficient and the temperature rise situation.

[0137] In some embodiments, optionally, it further includes: a second acquisition module for acquiring the water volume in the cooking appliance; and a first control module for controlling the working state of the cooking appliance according to the water volume and the remaining cooking time.

[0138] In some embodiments, optionally, the first control module includes: a first control sub-module for controlling the cooking appliance to give a water addition prompt when the water volume is less than the first threshold; and a second control sub-module for controlling the cooking appliance to continue cooking when the water volume is greater than or equal to the first threshold; wherein the first threshold is determined according to the remaining cooking time.

[0139] In some embodiments, optionally, the second control sub-module includes: a first control unit configured to control the cooking appliance to reduce the heating power when the water volume is greater than or equal to a first threshold and less than a second threshold; a second control unit configured to control the cooking appliance to maintain the current heating power when the water volume is greater than or equal to the second threshold and less than a third threshold; a third control unit configured to control the cooking appliance to increase the heating power when the water volume is greater than or equal to the third threshold; wherein the second threshold is greater than the first threshold, and the third threshold is greater than the second threshold.

[0140] In some embodiments, optionally, the first acquisition module includes: a second acquisition sub-module configured to control the cooking appliance to operate at a target heating power and acquire the temperature in the cooking cavity; a fourth determination sub-module configured to determine the change time for the temperature to reach the target temperature threshold from the initial temperature after the temperature has reached the target temperature threshold for a target duration; a fifth determination sub-module configured to determine the temperature rise situation based on the initial temperature, the target temperature threshold, and the change time.

[0141] As Figure 3 shown, according to a third aspect of the present invention, there is provided an electronic device 300, including a processor 302, a memory 304, and a program or instruction stored on the memory 304 and executable on the processor 302. When the program or instruction is executed by the processor 302, it implements the control method of the cooking appliance provided in the first aspect.

[0142] The electronic device provided by the present invention includes a processor, a memory, and a program or instruction stored on the memory and executable on the processor.

[0144] The readable storage medium provided by the present invention has a program or instruction stored thereon. Since the program or instruction implements the control method of the cooking appliance provided in the first aspect when executed by a processor, the readable storage medium provided by the present invention has all the beneficial effects of the control method of the cooking appliance provided in the first aspect, which will not be elaborated herein one by one.

[0145] A computer-readable storage medium can be a tangible device that can retain and store instructions for use by an instruction execution device. The 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 above devices, but is not limited thereto. A non-exhaustive list of more specific examples of the computer-readable storage medium includes: a portable computer floppy disk, a hard disk, a random access memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), a static random access memory (SRAM), a portable compact disc read-only memory (CD-ROM), a digital versatile disc (DVD), a memory card, a floppy disk, a coding mechanical device (such as a punched card or a groove with a raised structure recording instructions), and any suitable combination of the above devices. The computer-readable storage medium used herein should not be construed as a signal itself, such as a radio wave or other freely propagating electromagnetic wave, an electromagnetic wave propagating through a waveguide or other transmission medium, or an electrical signal transmitted through a wire, etc.

[0146] According to a fifth aspect of the present invention, there is provided a cooking appliance, comprising: a control device of the cooking appliance provided in the second aspect; or an electronic device provided in the third aspect; or a readable storage medium provided in the fourth aspect.

[0147] Since the cooking appliance provided by the present invention includes the control device of the cooking appliance provided in the second aspect; or the electronic device provided in the third aspect; or the readable storage medium provided in the fourth aspect, the cooking appliance provided by the present invention has all the beneficial effects of the control device of the cooking appliance provided in the second aspect; or the electronic device provided in the third aspect; or the readable storage medium provided in the fourth aspect, and will not be elaborated one by one herein.

[0148] Among them, the cooking appliance can be an electric steam cooker, an electric cooking pot, an electric rice cooker, an electric pressure cooker, or other cooking appliances.

[0149] As Figures 4 to 8 shown, according to a sixth aspect of the present invention, there is provided a cooking appliance 400, comprising: a steam generating device 410; a steamer 430 disposed on the steam generating device 410, the steamer 430 including a cooking cavity 432; a temperature detection assembly 440 disposed on the steam generating device 410 for detecting the temperature inside the cooking cavity 432; a controller 450 disposed on the steam generating device 410 and electrically connected to the temperature detection assembly 440 and the steam generating device 410; wherein, the controller 450 is configured to, during the cooking process, obtain the temperature rise condition inside the cooking cavity 432 according to the temperature detection assembly 440; determine the weight of the ingredients according to the temperature rise condition and the types of ingredients inside the cooking cavity 432; and determine the remaining cooking time of the steam generating device 410 according to the weight.

[0150] The cooking appliance 400 provided by the present invention includes a steam generating device 410, a steamer 430, and a temperature detection component 440. The steamer 430 is disposed on the steam generating device 410. The steamer 430 includes a cooking cavity 432. Ingredients can be placed in the cooking cavity 432 of the steamer 430. The steam generated by the steam generating device 410 can cook the ingredients in the steamer 430. The temperature detection component 440 can detect the temperature in the cooking cavity 432 of the steamer 430. The controller 450 is electrically connected to the temperature detection component 440 and the steam generating device 410. Thus, the controller 450 can obtain the temperature rise situation in the cooking cavity 432 of the cooking appliance 400 through the temperature detection component 440, determine the weight of the ingredients according to the temperature rise situation and the type of the ingredients in the cooking cavity 432, and determine the remaining cooking time required for cooking according to the weight of the ingredients.

[0151] Among them, the type of the ingredients can be input into the cooking appliance 400 by the user, or can be automatically recognized by the cooking appliance 400 through components such as a camera or a radar.

[0152] Moreover, when the temperature in the cooking cavity 432 rises, its temperature rise situation will be affected by the weight of the ingredients. Therefore, the temperature rise situation in the cooking cavity 432 can objectively reflect the weight of the ingredients. And, the required cooking time for ingredients of different weights is also different. Therefore, the remaining cooking time can be determined according to the weight of the ingredients, so that the cooking appliance 400 can accurately match the cooking time and improve the cooking effect of the cooking appliance 400.

[0153] As Figure 7 and Figure 8 shown, in some embodiments, optionally, the steam generating device 410 includes a heating element 412 and a heating cavity 418. The heating element 412 is used to heat the heating cavity 418.

[0154] In this embodiment, the steam generating device 410 includes a heating element and a heating cavity 418. The heating element 412 is used to heat the heating cavity 418. Thus, when there is water in the heating cavity 418, the water in the heating cavity 418 can be heated to generate steam, and the steam enters the cooking cavity 432 to realize the cooking of the ingredients.

[0155] As Figure 7 and Figure 8 shown, in some embodiments, optionally, the heating cavity 418 includes a first heating cavity 420 and a second heating cavity 422. The heating element 412 includes a first heating element 414 and a second heating element 416. The first heating element 414 is used to heat the inside of the first heating cavity 420, and the second heating element 416 is used to heat the inside of the second heating cavity 422. The controller 450 is electrically connected to the first heating element 414 and the second heating element 416.

[0156] In this embodiment, the heating chamber 418 includes a first heating chamber 420 and a second heating chamber 422, the heating element 412 includes a first heating element 414 and a second heating element 416. The first heating element 414 is used to heat the interior of the first heating chamber 420, and the second heating element 416 is used to heat the interior of the second heating chamber 422. The first heating chamber 420 and the second heating chamber 422 can simultaneously provide steam to the cooking chamber 432, or the first heating chamber 420 and the second heating chamber 422 can separately provide steam to the cooking chamber 432.

[0157] Thus, the two heating elements 412 and the two heating chambers 418 can enable the cooking appliance 400 to have a larger adjustment range of heating power.

[0158] As Figure 8 shown, in some embodiments, optionally, the cooking chamber 432 includes a first cavity 434 and a second cavity 436. The first cavity 434 includes a first state in communication with the first heating chamber 420, and a second state in communication with both the first heating chamber 420 and the second heating chamber 422. The second cavity 436 includes a third state in communication with the second heating chamber 422, and a fourth state in communication with both the first heating chamber 420 and the second heating chamber 422.

[0159] In this embodiment, the cooking chamber 432 includes a first cavity 434 and a second cavity 436. In the case of the first state of the first cavity 434, the first cavity 434 is in communication with the first heating chamber 420, that is, the first heating chamber 420 provides steam to the first cavity 434. In the case of the second state of the first cavity 434, the first cavity 434 is in communication with both the first heating chamber 420 and the second heating chamber 422, that is, the first heating chamber 420 and the second heating chamber 422 jointly provide steam to the first cavity 434.

[0160] In the case of the third state of the second cavity 436, the second cavity 436 is in communication with the second heating chamber 422, that is, the second heating chamber 422 provides steam to the second cavity 436. In the case of the fourth state of the second cavity 436, the second cavity 436 is in communication with both the first heating chamber 420 and the second heating chamber 422, that is, the first heating chamber 420 and the second heating chamber 422 jointly provide steam to the second cavity 436.

[0161] In some embodiments, optionally, when the cooking appliance 400 is in the temperature rise stage, the controller 450 controls the first heating element 414 and the second heating element 412 to work simultaneously; the controller 450 controls the working states of the first heating element 414 and the second heating element 416 according to the remaining cooking time and the water volume in the cooking appliance 400.

[0162] In this embodiment, during the temperature rise stage of the cooking appliance 400, that is, the initial stage when the cooking appliance 400 starts cooking, the first heating element 414 and the second heating element 412 are controlled to work simultaneously, which increases the amount of steam provided to the cooking cavity 432, improves the temperature rise speed of the cooking cavity 432, and enhances the cooking speed of the cooking appliance 400. Moreover, rapid heating can quickly denature the surface of the food ingredients, achieving the effect of locking in water and improving the taste of the food ingredients, that is, enhancing the cooking effect of the cooking appliance 400.

[0163] Furthermore, after determining the remaining cooking time, the controller 450 obtains the water volume in the cooking appliance 400, and controls the working states of the first heating element 414 and the second heating element 416 according to the water volume in the cooking appliance 400 and the remaining cooking time. After the remaining cooking time is determined, it can be determined whether the current water volume in the cooking appliance 400 is sufficient to support the entire cooking process. Thus, the working states of the first heating element 414 and the second heating element 416 can be controlled based on the remaining cooking time and the water volume in the cooking appliance 400, thereby enhancing the cooking effect of the cooking appliance 400.

[0164] In some embodiments, optionally, when the water volume is greater than or equal to the fourth threshold and less than the fifth threshold, the controller 450 controls one of the first heating element 414 and the second heating element 416 to turn off and the other to work; when the water volume is greater than or equal to the fifth threshold and less than the sixth threshold, the controller 450 controls the first heating element 414 and the second heating element 416 to maintain their current working states; when the water volume is greater than or equal to the sixth threshold, the controller 450 controls the first heating element 414 and / or the second heating element 416 to increase the heating power; wherein, the fifth threshold is greater than the fourth threshold, the sixth threshold is greater than the fifth threshold, and the fourth threshold is determined according to the remaining cooking time.

[0165] In this embodiment, when the water volume is greater than or equal to the fourth threshold and less than the fifth threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance 400. However, it is not sufficient to support the simultaneous operation of the two heating elements 412. Therefore, the controller 450 controls one of the first heating element 414 and the second heating element 416 to turn off and the other to turn on.

[0166] Among them, the fourth threshold is a set value, which can be the water volume required for the cooking appliance 400 to cook the remaining time using a single heating element 412, and the fifth threshold is a set value, which can be the water volume required for the cooking appliance 400 to cook the remaining time using two heating elements 412.

[0167] When the water volume is greater than or equal to the fifth threshold and less than the sixth threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance 400, and is sufficient to support the simultaneous operation of the two heating elements 412. Therefore, the controller 450 controls the first heating element 414 and the second heating element 416 to continue to operate.

[0168] Among them, the sixth threshold is a set value, which can be the water volume required for the cooking appliance 400 to cook the remaining time using the two heating elements 412.

[0169] When the water volume is greater than the sixth threshold, it indicates that the current water volume is sufficient to support the cooking process of the cooking appliance 400, and is sufficient to support the two heating elements 412 to operate simultaneously at a greater heating power. Therefore, the controller 450 controls the first heating element 414 and the second heating element 416 to increase the heating power for operation.

[0170] According to the above control logic, it is possible to ensure that the cooking time is shortened as much as possible when the cooking is completed.

[0171] As Figure 6 and Figure 7 shown, in some embodiments, optionally, the temperature detection component 440 is used to detect the temperature inside the first cavity 434.

[0172] In this embodiment, the temperature detection component 440 is used to detect the temperature inside the first cavity 434, that is, the temperature detection component 440 reflects the temperatures of the first cavity 434 and the second cavity 436 through the first cavity 434.

[0173] As Figure 8 shown, in some embodiments, optionally, the temperature detection component 440 includes a first temperature detection element 442 and a second temperature detection element 444. The first temperature detection element 442 is used to detect the temperature inside the first cavity 434, and the second temperature detection element 444 is used to detect the temperature inside the second cavity 436. The controller 450 is electrically connected to the first temperature detection element 442 and the second temperature detection element 444.

[0174] In this embodiment, the temperature detection component 440 includes a first temperature detection element 442 and a second temperature detection element 444. The first temperature detection element 442 is used to detect the temperature inside the first cavity 434, and the second temperature detection element 444 is used to detect the temperature inside the second cavity 436. The controller 450 is electrically connected to the first temperature detection element 442 and the second temperature detection element 444, that is, the first cavity 434 and the second cavity 436 are respectively based on the first temperature detection element 442 and the second temperature detection element 444, improving the accuracy of obtaining the temperature inside the cooking cavity 432.

[0175] As Figure 5 and Figure 6As shown, in some embodiments, optionally, the steam generating device 410 further includes a water receiving tray 426. The heating cavity 418 is disposed on the water receiving tray 426. The steam generating device 410 further includes a liquid storage cavity 424. The water receiving tray 426 is located above the liquid storage cavity 424. The heating cavity 418 and the liquid storage cavity 424 are in communication. Thus, the heating element 412 does not need to heat the water in the entire liquid storage cavity 424, and only needs to heat a small amount of water to generate steam, thereby improving the steam generation speed.

[0176] Wherein, the cooking appliance 400 further includes a water adding box 480. The water adding box 480 is disposed on the steam generating device 410. And the water adding box 480 can move to a first position where it extends into the steam generating device 410, and can also move to a second position where it is pulled out of the steam generating device 410.

[0177] When the water adding box 480 moves to the first position, the water adding box 480 is located inside the steam generating device 410. When the water adding box 480 moves to the second position, at least a part of the water adding box 480 is located outside the steam generating device 410. Thus, water can be added into the liquid storage cavity 424 through the water adding box 480.

[0178] As Figure 8 shown, in some embodiments, optionally, the steamer 430 includes a first steamer 4302 and a second steamer 4304. The first cavity 434 is disposed in the first steamer 4302, and the second cavity 436 is disposed in the second steamer 4304. The first steamer 4302 is disposed on the steam generating device 410, and the second steamer 4304 is disposed on the first steamer 4302. The first steamer 4302 includes a steam channel 4306, and the steam channel 4306 communicates the second heating cavity 422 and the second cavity 436.

[0179] As Figure 5 shown, in some embodiments, optionally, a steaming tray 438 is disposed in the steamer 430 for placing food ingredients.

[0180] As Figures 4 to 8 shown, the cooking appliance 400 provided by the present invention includes a steam generating device 410 and a steamer 430.

[0181] The steam generating device 410 includes a plurality of heating elements 412 disposed at the bottom, and further includes a water tank 428 and a cover or a water receiving tray 426 disposed above the heating elements 412.
