[0040] The control method of the cooking appliance 100 according to an embodiment of the present application will be described below with reference to the accompanying drawings.

[0041] Referring to Figures 1-5 As shown, the cooking appliance 100 according to an embodiment of the present application can include a pot assembly 10 and a plurality of food containers 40.

[0042] Specifically, the plurality of food containers 40 are placed in the pot assembly 10 alternatively. And when different food containers 40 are fitted in the pot assembly 10, the cooking appliance 100 can work in different cooking modes to achieve different cooking functions.

[0043] The cooking appliance 100 works in different cooking modes by changing the type of the food container 40 fitted in the pot assembly 10, so that the cooking appliance 100 can meet more cooking needs and achieve different cooking effects.

[0044] As Figure 6 As shown, the control method of the cooking appliance 100 according to an embodiment of the present application can include the following steps:

[0045] S1: detecting the type of the current food container 40 placed in the pot assembly 10;

[0046] S2: controlling the cooking mode of the cooking appliance 100 according to the type of the current food container 40.

[0047] Thus, after the user matches the required food container 40 to the pot body assembly 10, the cooking appliance 100 can automatically control the cooking appliance 100 to work according to the type of the food container 40 used by the user, without the user manually selecting the cooking mode, simplifying the user operation steps and making the use more convenient. Moreover, it avoids the situation that the cooking mode selected by the user does not match the type of the food container 40 used, resulting in that the cooking appliance 100 cannot work normally or the food container 40 is damaged. For example, the user uses a basket for air frying, but selects a pressure cooking mode, which can cause the cooking appliance 100 to fail to normally build pressure.

[0048] In some embodiments, as shown in FIG. 1, the cooking appliance 100 can have a first cooking mode and a second cooking mode, and the plurality of food containers 40 can include a first food container 41 and a second food container 42. The step S2 of controlling the cooking mode of the cooking appliance 100 according to the type of the current food container 40 can include the following steps: Figures 1-5

[0049] When it is determined that the current food container 40 is the first food container 41, the cooking appliance 100 is controlled to be in the first cooking mode; and when it is determined that the current food container 40 is the second food container 42, the cooking appliance 100 is controlled to be in the second cooking mode.

[0050] Of course, the plurality of food containers 40 can also include a third food container, a fourth food container, etc., and the corresponding cooking appliance 100 can also have a third cooking mode, a fourth cooking mode, etc., which are all within the protection scope of the present application.

[0051] For example, the cooking appliance 100 can include a detection assembly 70 and a control assembly in communication connection with the detection assembly 70. The detection assembly 70 can detect the type of the current food container 40 placed in the pot body assembly 10, and the control assembly can control the cooking mode of the cooking appliance 100 according to the detection result of the detection assembly 70, i.e., according to the type of the current food container 40.

[0052] In the embodiments in which the plurality of food containers 40 include the first food container 41 and the second food container 42, when the detection assembly 70 detects that the food container 40 placed in the pot body assembly 10 is the first food container 41, the control assembly can control the cooking appliance 100 to be in the first cooking mode; and when the detection assembly 70 detects that the food container 40 placed in the pot body assembly 10 is the second food container 42, the control assembly can control the cooking appliance 100 to be in the second cooking mode. The automatic selection and switching of the first cooking mode and the second cooking mode are realized.

[0053] ​According to the control method of the cooking utensil 100, different cooking modes can be realized by replacing the food container 40 matched with the pot assembly 10, the cooking demand of the user can be met, and the cooking utensil 100 can automatically execute the corresponding cooking mode without manual selection of the user, the operation is simplified, and the used cooking accessory is matched with the executed cooking mode, and normal cooking is ensured.

[0054] According to some embodiments of the present application, the detection assembly 70 is arranged in the pot assembly 10, and the detection assembly 70 has a first detection state and a second detection state. When the first food container 41 is placed in the pot assembly 10, the detection assembly 70 is in the first detection state, and at this time, the cooking utensil 100 can be controlled to be in the first cooking mode; when the second food container 42 is placed in the pot assembly 10, the detection assembly 70 is in the second detection state, and at this time, the cooking utensil 100 can be controlled to be in the second cooking mode. The type of the food container 40 is determined according to the different detection states of the detection assembly 70, the detection structure is simple, and the detection precision is high.

[0055] In the embodiments of the present application, the specific structure of the detection assembly 70 can be flexibly set according to actual conditions.

[0056] For example, in some embodiments, the detection assembly 70 can include a detection part arranged in the pot assembly 10, and the second food container 42 can be provided with a detection matching part. The detection part is used to detect the detection matching part. When the second food container 42 is placed in the pot assembly 10, the detection matching part is in the detection range of the detection part, so that the detection part can detect the detection matching part on the second food container 42. When the second food container 42 is not placed in the pot assembly 10 and the first food container 41 is placed in the pot assembly 10, the detection matching part is out of the detection range of the detection part, and the detection part cannot detect the detection matching part. Thus, in the state that the detection part detects the detection matching part on the second food container 42, it can be determined that the second food container 42 is placed in the pot assembly 10; in the state that the detection part does not detect the detection matching part, it can be determined that the first food container 41 is placed in the pot assembly 10. The type of the food container 40 is identified by whether the detection part can detect the detection matching part, only one detection matching part is needed, and the detection logic of the detection part is simple, which simplifies the structure of the detection assembly 70 and reduces the cost.

[0057] Of course, according to the above description, the technical solution that the first food container 41 is provided with the detection matching part and the second food container 42 is not provided with the detection matching part is understandable to those skilled in the art.

[0058] In some embodiments, the detection part can be a dry reed, and the detection matching part can be a magnetic piece. When the second food container 42 is placed in the pot assembly 10, the magnetic piece is within the detection range of the dry reed, forming a feedback detection, the dry reed is turned on, and the control assembly controls the cooking appliance 100 to be in the second cooking mode; when the first food container 41 is placed in the pot assembly 10, the dry reed is turned off, and the control assembly controls the cooking appliance 100 to be in the first cooking mode.

[0059] In some embodiments, the detection assembly 70 can be a weight sensor, which can detect the weight of the food container 40 placed in the pot assembly 10 to distinguish the type of the food container 40 according to the weight of the food container 40. For example, the first food container 41 can be a metal inner pot, and the second food container 42 can be a frying basket with a hollow structure, and the weight of the inner pot is greater than that of the frying basket. In addition, the weight sensor can also be used to detect the weight of the food container 40 and the food material in the food container 40 during cooking, so as to control the cooking parameters (such as cooking temperature, time, etc.) according to the weight.

[0060] In some embodiments, the detection assembly 70 can be a micro switch, which is triggered to be in an on state when the first food container 41 is placed in the pot assembly 10, and is not triggered to be in an off state when the second food container 42 is placed in the pot assembly 10. The on-off state of the micro switch can be used to control the cooking mode of the cooking appliance 100. Of course, the micro switch can also be triggered when the second food container 42 is placed in the pot assembly 10.

[0061] In some embodiments, as shown in Figures 1-5 and Figure 7 The detection assembly 70 can include two signal transceiver assemblies 73, and the detection state of the detection assembly 70 can be determined according to the on-off state of the two signal transceiver assemblies 73, so as to determine the type of the food container 40 placed in the pot assembly 10.

[0062] For example, when both of the two signal transceiver assemblies 73 are in an off state, the detection assembly 70 is in a first detection state, and the current food container 40 is the first food container 41; when one of the two signal transceiver assemblies 73 is in an on state and the other is in an off state, the detection assembly 70 is in a second detection state, and the current food container 40 is the second food container 42.

[0063] The signal transceiver assembly 73 can be an optical signal detection or an electrical signal detection. The type of the food container 40 can be determined according to the on-off state of the two signal transceiver assemblies 73, which is not easy to misjudge, and the signal transceiver assembly 73 does not need to be in mechanical contact with the food container 40, which is beneficial to prolong the service life of the signal transceiver assembly 73.

[0064] In some embodiments, as shown in Figures 1-3 and Figure 7 The signal transceiver assembly 73 includes a signal transmitting part 731 and a signal receiving part 732. The signal transmitting part 731 can transmit a signal such as an optical signal or an electrical signal. When the signal receiving part 732 receives the signal transmitted by the signal transmitting part 731, the signal transceiver assembly 73 is turned on. When the second food container 42 is placed on the pot assembly 10, the second food container 42 can block the signal transmitting part 731 and the signal receiving part 732 of one of the signal transceiver assemblies 73, so that the one signal transceiver assembly 73 is turned off, and the other signal transceiver assembly 73 is turned on. When the first food container 41 is placed on the pot assembly 10, the first food container 41 can block the signal transmitting part 731 and the signal receiving part 732 of both of the signal transceiver assemblies 73, so that both of the signal transceiver assemblies 73 are turned off.

[0065] When only one of the signal transceiver assemblies 73 is turned on, it is determined that the second food container 42 is placed on the pot assembly 10. When both of the signal transceiver assemblies 73 are turned off, it is determined that the first food container 41 is placed on the pot assembly 10.

[0066] In some embodiments, as shown in Figure 7 When both of the signal transceiver assemblies 73 are turned on, it is determined that no food container 40 is placed on the pot assembly 10. The control assembly can control the reminding assembly of the cooking appliance 100 to issue a container placement reminding information (i.e., issue a reminding information for selecting a cooking mode).

[0067] In some embodiments, as shown in Figure 1 and Figure 4 The pot assembly 10 has a receiving cavity 101, and the food container 40 can be placed in the receiving cavity 101. The signal transmitting part 731 and the signal receiving part 732 are arranged on the cavity wall of the receiving cavity 101 and are oppositely arranged. The signal transmitted by the signal transmitting part 731 passes through the receiving cavity 101 and is received by the signal receiving part 732, so that the signal transceiver assembly 73 is turned on. If the signal transmitted by the signal transmitting part 731 is blocked by a component in the receiving cavity 101, the signal receiving part 732 cannot receive the signal, and the signal transceiver assembly 73 is turned off. Therefore, by oppositely arranging the signal transmitting part 731 and the signal receiving part 732 on the cavity wall of the receiving cavity 101, the blocking states of the signal transmitting part 731 and the signal receiving part 732 by different food containers 40 are different when different food containers 40 are used, so that the signal on-off states of the two signal transceiver assemblies 73 are different. The detection mode of the detection assembly 70 is simple and has high accuracy and is not prone to misjudgment.

[0068] In some embodiments, as shown in Figures 1-5As shown, a support member is provided inside the receiving cavity 101 to support the food container 40 placed inside the receiving cavity 101. A signal transmitting unit 731 and a signal receiving unit 732 are provided on the side wall of the receiving cavity 101. The longitudinal distance between the two signal transceiver components 73 and the support member can be L1 and L2 respectively; in other words, the two signal transceiver components 73 are longitudinally spaced and positioned on the side wall of the receiving cavity 101. The height of the first food container 41 is L3, and the height of the second food container 42 is L4. Wherein, L1 < L4 < L2 < L3.

[0069] Therefore, as Figures 1-3 As shown, when the second food container 42 is placed inside the receiving cavity 101, the top of the second food container 42 is positioned between the two signal transceiver components 73. This allows the second food container 42 to block the signal transmitting part 731 and the signal receiving part 732 of the lower-height signal transceiver component 73, thus disconnecting its signal, while allowing the signal transmitting part 731 and the signal receiving part 732 of the higher-height signal transceiver component 73 to conduct signals. Figure 4 and Figure 5 As shown, when the first food container 41 is placed in the receiving cavity 101, the top of the first food container 41 is higher than the two signal transceiver components 73, so that the first food container 41 can simultaneously block the signal transmitting part 731 and the signal receiving part 732 of the two signal transceiver components 73, so that the two signal transceiver components 73 disconnect signals at the same time.

[0070] In some embodiments of the present invention, such as Figure 2 and Figure 3 As shown, the pot assembly 10 may include a housing 11 and an outer pot 12, with the outer pot 12 disposed within the housing 11. The sidewall of the outer pot 12 may have a first through-hole 121 and a second through-hole 122, which are arranged opposite to each other. A transmitting unit 731 is located between the housing 11 and the outer pot 12 and opposite to the first through-hole 121, while a signal receiving unit 732 is located between the housing 11 and the outer pot 12 and opposite to the second through-hole 122. The signal emitted by the transmitting unit 731 can sequentially pass through the first through-hole 121, the receiving cavity 101, and the second through-hole 122 to propagate to the signal receiving unit 732. The housing 11 and the outer pot 12 can protect the signal transmitting unit 731 and the signal receiving unit 732, preventing damage or contamination of the signal transceiver assembly 73, which would affect the detection performance.

[0071] It should be noted that in the embodiment with two signal transceiver components 73, the signal transmitting part 731 of the two signal transceiver components 73 can be opposite to the same first via 121, or can be opposite to two first vias 121 respectively. The two signal receiving parts 732 can be opposite to the same second via 122, or can be opposite to two second vias 122 respectively.

[0072] Of course, according to the above description, the technical solution that only one signal transceiver assembly 73 is signal on when the first food container 41 is placed in the pot assembly 10, and both signal transceiver assemblies 73 are signal off when the second food container 42 is placed in the pot assembly 10, is understandable to those skilled in the art.

[0073] In some embodiments of the present application, as shown in Figures 1-5 The cooking appliance 100 can further include a heating assembly 20 and an air fan assembly 30. The heating assembly 20 is arranged in the pot assembly 10, and the heating assembly 20 is used to directly conduct heat to the food container 40 placed in the pot assembly 10, or indirectly heat the food container 40 by heating air to achieve the cooking of the food in the food container 40.

[0074] In some embodiments, the heating assembly 20 can be arranged in the containing cavity 101 of the pot assembly 10, and the food container 40 can be supported on the heating assembly 20, that is, the heating assembly 20 is formed as a support for supporting the food container 40. The air fan assembly 30 can be arranged in the pot assembly 10 or in the cover assembly 60, and the air fan assembly 30 can drive the air flow in the pot assembly 10. When the second food container 42 is placed in the pot assembly 10, the air heated by the heating assembly 20 can be in full contact with the food material in the second food container 42 through the driving of the air fan assembly 30, improving the uniformity of the coloring of the food material.

[0075] In some embodiments, when the first food container 41 is placed in the containing cavity 101, the first cooking cavity 411 of the first food container 41 is not communicated with the containing cavity 101 (that is, the bottom wall and the side wall of the first food container 41 are continuous walls), and the heating assembly 20 can heat the first food container 41 to warm up the first food container 41 and heat the food in the first cooking cavity 411.

[0076] In some embodiments, the first food container 41 can be in contact with the heating assembly 20, that is, in surface contact, which can improve the heat conduction efficiency between the first food container 41 and the heating assembly 20, and improve the uniformity of the heating of the food in the first cooking cavity 411.

[0077] In some embodiments, when the second food container 42 is placed in the receiving cavity 101, an air duct 423 is defined between the second food container 42 and the pot body assembly 10. The second food container 42 may be provided with an air passage 422, which connects the air duct 423 and the second cooking cavity 421 of the second food container 42 (i.e., the cooking cavity of the second food container 42, hereinafter referred to as the second cooking cavity 421). In some embodiments, at least one of the top wall and side wall of the second food container 42 may be provided with an air passage 422, or the top opening of the second food container 42 may be formed as an air passage 422 and communicate with the receiving cavity 101. In the second cooking mode, the fan assembly 30 drives the air heated by the heating assembly 20 to circulate between the second cooking cavity 421 and the air duct 423 to heat the food in the second cooking cavity 421. Compared with the heat transfer method of heat conduction by the first food container 41, the method of directly heating the food with hot air can improve the dehydration and coloring effect of the food and achieve different cooking functions.

[0078] In some embodiments, the bottom wall of the second food container 42 is spaced apart from the bottom wall of the receiving cavity 101 by a certain gap, and the side wall of the second food container 42 is spaced apart from the side wall of the receiving cavity 101 by a certain gap, so that an air duct 423 is formed between the second food container 42 and the cavity wall of the receiving cavity 101. By setting the air duct 423, the air flow resistance is reduced, and the air can circulate fully in the air duct 423 and the second cooking cavity 421, thereby improving the uniformity and efficiency of food heating.

[0079] In some specific embodiments, such as Figure 1 As shown, the bottom wall of the second food container 42 is provided with an air passage 422, and an air duct 423 is formed between the second food container 42 and the cavity wall of the receiving cavity 101. Driven by the fan assembly 30, the air in the air duct 423 can enter the second cooking cavity 421 through the air passage 422, and then return to the air duct 423 through the top opening of the second cooking cavity 421. Alternatively, the air in the air duct 423 can enter the second cooking cavity 421 through the top opening of the second cooking cavity 421, and then return to the air duct 423 through the air passage 422, thereby realizing the circulation of air. Furthermore, the air passage 422 and the top opening of the second cooking cavity 421 are arranged opposite to each other, allowing air to flow through a larger area of ​​the second cooking cavity 421, thereby improving the uniformity of heating of food in each area.

[0080] In some other specific embodiments, the side wall of the second food container 42 is provided with air passage holes 422, and at least two air passage holes 422 are arranged opposite to each other (for example, some air passage holes 422 are located on the left side of the second cooking cavity 421, and some air passage holes 422 are located on the right side of the second cooking cavity 421). Air in the air duct 423 can enter and exit the second cooking cavity 421 through the oppositely arranged air passage holes 422, so that the food in each area of ​​the second cooking cavity 421 is heated evenly.

[0081] In some embodiments of the fan assembly 30, the fan can be arranged opposite to the air passage hole 422, or the fan can be arranged opposite to the top opening of the second cooking cavity 421, so as to improve the efficiency of air passing through the air passage hole 422 or the top opening to enter or exit the second cooking cavity 421, thereby improving the effect of air circulation.

[0082] The mounting structure of the fan assembly 30 according to some embodiments of the present application will be described below with reference to the accompanying drawings.

[0083] In some embodiments of the present application, as shown in Figure 1 The fan assembly 30 can be mounted at the bottom of the pot assembly 10, and the fan assembly 30 can form positive pressure or negative pressure in the air duct 423 located at the lower part of the containing cavity 101 when it is working, so as to make the air in the entire air duct 423 flow in and out of the second cooking cavity 421. The bottom of the pot assembly 10 has a larger mounting space, which facilitates the installation of the fan assembly 30, improves the space utilization, and reduces the transverse size of the cooking appliance 100. In the embodiments in which the heating assembly 20 is arranged at the lower part of the containing cavity 101, the fan assembly 30 is closer to the heating assembly 20, which can drive the air around the heating assembly 20 to flow more fully, and the air heated by the heating assembly 20 can flow rapidly to the low-temperature area, which is conducive to improving the uniformity of the temperature in the containing cavity 101 and the second cooking cavity 421.

[0084] In some embodiments of the present application, the fan assembly 30 can be mounted at the side of the pot assembly 10, and the fan assembly 30 can form positive pressure or negative pressure in the air duct 423 located at the side of the containing cavity 101 when it is working, so as to make the air in the entire air duct 423 flow in and out of the second cooking cavity 421. Driving the air in the containing cavity 101 to flow from the side of the containing cavity 101 is conducive to making the air in the upper part and the lower part of the containing cavity 101 circulate more rapidly, thereby improving the uniformity of the temperature in the containing cavity 101 and the second cooking cavity 421. In the embodiments in which the heating assembly 20 is arranged at the lower part of the containing cavity 101, the upper part of the containing cavity 101 is farther away from the heating assembly 20, and the fan assembly 30 is located between the heating assembly 20 and the top of the containing cavity 101 in the up-down direction, which is conducive to the flow of hot air from the lower part to the upper part of the containing cavity 101.

[0085] In some embodiments in which the cooking appliance 100 comprises the second cover assembly 62, the fan assembly 30 can be arranged in the second cover assembly 62 to drive air flow in and out of the second cooking cavity 421 from the upper portion of the containing cavity 101. In embodiments in which the heating assembly 20 is arranged in the lower portion of the containing cavity 101, the fan assembly 30 can form a positive pressure or a negative pressure in the area far from the heating assembly 20 to accelerate the hot air in the area close to the heating assembly 20 to flow to the low-temperature area quickly, thereby achieving the uniformity of the temperature in the containing cavity 101 and the second cooking cavity 421.

[0086] In some embodiments of the present application, as shown in Figure 1 and Figure 4 The heating assembly 20 can comprise two heating elements, i.e., a first heating element 21 and a second heating element 22. The second heating element 22 is arranged below the first heating element 21. In the first cooking mode of the cooking appliance 100, the first heating element 21 is controlled to work, but the second heating element 22 is not controlled to work, so that the first heating element 21 close to the first food container 41 can exchange heat sufficiently, thereby improving the cooking efficiency and the cooking effect. In the second cooking mode of the cooking appliance 100, the first heating element 21 is not controlled to work, but the second heating element 22 and the fan assembly 30 are controlled to work. The working heating element is far from the second food container 42, which is convenient for the second food container 42 to contact with the air in the air duct 423 sufficiently, and avoids that the wall surface of the second food container 42 is locally heated too much to affect the cooking effect.

[0087] In addition, the first heating element 21 and the second heating element 22 are used for different cooking modes, respectively, so that the shapes and control logics of the two heating elements can be set separately without affecting each other, thereby reducing the design difficulty and improving the cooking control effect. In some embodiments, the first heating element 21 can comprise a heating element and a heat-conducting plate, and the heat-conducting plate is in contact with the bottom wall surface of the first food container 41 to improve the heating uniformity and the heat exchange efficiency. The second heating element 22 can be a heating pipe, and the surface area of the heating pipe is larger, which can contact with the air sufficiently to exchange heat and improve the air frying efficiency.

[0088] In embodiments in which the first heating element 21 and the second heating element 22 are used for different cooking modes, respectively, the first heating element 21 can be mounted to the pot assembly 10 to reduce the weight of the first food container 41 and facilitate the cleaning and taking out of the first food container 41. Alternatively, the first heating element 21 can be mounted to the first food container 41, and when the first food container 41 is placed in the containing cavity 101, the first heating element 21 is located in the containing cavity 101, and when the first food container 41 is taken out, the first heating element 21 can be taken out together, which is also within the protection scope of the present application.

[0089] In some embodiments of the present application, when the cooking appliance 100 is in the first cooking mode, the first heating element 21 is controlled to work, but the second heating element 22 does not work; and when the cooking appliance 100 is in the second cooking mode, the first heating element 21 is controlled to work, and the second heating element 22 and the fan assembly 30 work. In other words, the first heating element 21 is used for both the first cooking mode and the second cooking mode. In the second cooking mode, the heating area in contact with the air is further increased by heating through two heating elements, and the air frying effect is further improved.

[0090] It should be noted that the working of the first heating element 21 and the working of the second heating element 22 herein are to be understood in a broad sense. That is, the first heating element 21 and the second heating element 22 can work simultaneously, alternately, or staggered, etc., as long as in the second cooking mode, both the first heating element 21 and the second heating element 22 can heat the air in the accommodation cavity 101.

[0091] In embodiments of the present application, the first heating element 21 can be a combination of a hot plate or IH, etc., and the second heating element 22 can be a heat pipe, infrared, or hot plate, etc. The first heating element 21 and the second heating element 22 can be any combination of two heating modes.

[0092] In some embodiments of the present application, as shown in Figure 1 and Figure 4 , the heating assembly 20 is located at the lower part of the accommodation cavity 101. When the food container 40 (the first food container 41 or the second food container 42) is placed in the accommodation cavity 101, the heating assembly 20 is located below the food container 40 to heat the food from the lower side. When the first food container 41 is placed in the accommodation cavity 101, as shown in Figure 4 , the bottom wall of the first food container 41 is in contact with the heating assembly 20, that is, in surface contact, which can support and limit the first food container 41 on one hand, and improve the heat conduction efficiency between the first food container 41 and the heating assembly 20 on the other hand, thereby improving the uniformity of the heat received by the food in the first cooking cavity 411. When the second food container 42 is placed in the accommodation cavity 101, as shown in Figure 1 , the bottom wall of the second food container 42 can be partially in contact with the heating assembly 20 or spaced apart by a certain gap. The air at the lower part of the accommodation cavity 101 has a natural upward tendency after being heated by the heating assembly 20, which is conducive to improving the internal thermal field circulation and achieving the uniformity of the heat received by the food.

[0093] In some specific embodiments of the present application, the first cooking mode can be a pressure cooking mode, and the second cooking mode can be an air frying cooking mode. Correspondingly, the first food container 41 can be an inner pot, which can form a sealed space in cooperation with the cover assembly 60, and the second food container 42 can be a frying basket, which has a hollow structure so that the space in the frying basket can communicate with the space between the frying basket and the pot assembly 10, facilitating the circulation of hot air. The cooking appliance 100 is formed as a pressure-air frying all-in-one machine, which has both pressure cooking and air frying cooking modes, and has strong practicability.

[0094] In the pressure cooking mode, the heating assembly 20 can heat the food in the first food container 41 and can change the air pressure in the first cooking cavity 411 of the first food container 41. In the pressure cooking mode, the food can be processed by braising, boiling, stewing, etc., and the food cooking efficiency is high and the nutrient extraction effect is better.

[0095] In the air frying cooking mode, the heating assembly 20 can heat the air in the containing cavity 101, and the hot air enters the second cooking cavity 421 of the second food container 42 to realize the processing of food baking, frying, air frying, etc., and the food is heated uniformly and the baking effect is good.

[0096] In the embodiments of the present application, since heating is performed by the heating assembly 20 arranged on the pot assembly 10 in both the first cooking mode and the second cooking mode, the heating structure does not need to be arranged on the cover assembly 60, which is beneficial to simplify the structure of the cover assembly 60, reduce the number, volume and weight of the components of the cover assembly 60, and make it more labor-saving for the user to take and place the cover assembly 60. In addition, heating by the heating assembly 20 realizes the under-placed heat source, which is beneficial to more uniform coloring of the food.

[0097] In the embodiments in which the cover assembly 60 includes the first cover assembly 61 and the first cooking mode is the pressure cooking mode, as shown in FIG. 1, the first cover assembly 61 can close the top opening of the first food container 41, so that the first cooking cavity 411 is closed. When the heating assembly 20 heats the first food container 41, the air pressure in the first cooking cavity 411 can be increased to realize pressure cooking. Figure 4 In some embodiments, the first cover assembly 61 can include a cover body, an exhaust valve 611 and a sealing ring. The sealing ring is mounted to the cover body and sealingly cooperates with the top opening edge of the first food container 41 to close the top opening of the first food container 41. The exhaust valve 611 is arranged on the cover body and communicates with the first cooking cavity 411 to facilitate the adjustment of the pressure in the first cooking cavity 411.

[0098] In the embodiment of controlling the cooking mode by detecting the type of the food container 40 placed in the pot assembly 10, the same cover assembly 60 can be used in cooperation with the pot assembly 10 in the first cooking mode and the second cooking mode, that is, the cover assembly 60 does not need to be replaced when switching the cooking mode, and the user operation is simpler. In some embodiments, the cooking utensil 100 can only include the first cover assembly 61, and the first cover assembly 61 is covered on the pot assembly 10 in the first cooking mode and the second cooking mode. Of course, when the first cover assembly 61 is used in the second cooking mode, the first cover assembly 61 can be spaced apart from the top opening of the second food container 42 by a certain gap, so that the second cooking cavity 421 can communicate with the air duct 423 through the top opening, facilitating the circulation of hot air.

[0099] In the embodiment in which the cover assembly 60 includes the first cover assembly 61 and the second cover assembly 62, as shown in Figure 1 The second cover assembly 62 can also have a transparent area 621, through which the user can check the cooking state of the food in the second cooking cavity 421 at any time, facilitating the user to observe and grasp the cooking degree of the food, and improving the user experience. Specifically, as shown in Figure 1 The second cover assembly 62 can include a cover plate and a handle, and the handle is connected to the cover plate to facilitate the taking and placing of the second cover assembly 62. The cover plate can be a transparent glass plate to facilitate user observation.

[0100] According to some embodiments of the present application, the cooking utensil 100 can include a fuse, which is arranged adjacent to the heating assembly 20, so that the ambient temperature around the fuse increases during the operation of the heating assembly 20. The fuse can be safely protected according to the ambient temperature to avoid safety accidents caused by abnormal heating temperature of the heating assembly 20.

[0101] In some specific embodiments, the heating assembly 20 can include a first heating element 21 and a second heating element 22, and the distance between the fuse and the first heating element 21 is less than the distance between the fuse and the second heating element 22, so that the heating assembly 20 has the same heating power, the first heating element 21 radiates more heat around the fuse than the second heating element 22. In addition, in the first cooking mode, the heating power of the first heating element 21 is P1, and the second heating element 22 stops heating; in the second cooking mode, the heating power of the first heating element 21 is P2, and the heating power of the second heating element 22 is P3. Wherein, P1>P2.

[0102] Thus, in the first cooking mode, the fuse is only affected by the heat radiated by the first heating element 21, and when the first heating element 21 is abnormally heated, the ambient temperature around the fuse is too high, the contact temperature of the fuse is too high, and the fuse is blown. In the second cooking mode, the fuse is affected by the heat radiated by the first heating element 21 and the second heating element 22. The heating power of the first heating element 21 in the second cooking mode is less than that in the first cooking mode, and the heating power of the second heating element 22 is superimposed, so that the heat radiated by the first heating element 21 and the second heating element 22 around the fuse in the second cooking mode is basically the same as the heat radiated by the first heating element 21 around the fuse in the first cooking mode, realizing the safety protection of the single fuse.
