[0047] In the description of the present application, "first feature" and "second feature" can include one or more features, and the meaning of "a plurality of" is two or more. "Above" or "below" the second feature of the first feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature therebetween. "Above", "over" and "on" the second feature of the first feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is higher than the second feature in terms of horizontal height.

[0048] A cooking appliance 100 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0049] Referring to Figures 1-8 As shown, the cooking appliance 100 according to an embodiment of the present application has a first cooking mode and a second cooking mode, and the cooking appliance 100 includes a pot assembly 10, a food container 40, a heating assembly 20, and a fuse 80.

[0050] Specifically, the food container 40 is placed in the pot assembly 10 for holding food. The heating assembly 20 is provided in the pot assembly 10, and in the first cooking mode and the second cooking mode, the food container 40 is heated by the heating assembly 20 to achieve cooking of the food. In other words, the same heating assembly 20 is used for heating in different cooking modes, which simplifies the heating structure and reduces the cost.

[0051] In addition, as Figure 1 and Figure 3As shown, the fuse 80 is arranged adjacent to the heating assembly 20, so that the ambient temperature around the fuse 80 is increased during the operation of the heating assembly 20, and the fuse 80 can be protected according to the ambient temperature to avoid safety accidents caused by abnormal heating temperature of the heating assembly 20.

[0052] In the embodiment of the present application, the fuse 80 is arranged such that, in the first cooking mode and the second cooking mode, the fuse 80 is fused when the contact temperature of the fuse 80 reaches the preset temperature. In other words, the fuse 80 can be used for safety protection in both the first cooking mode and the second cooking mode, so that the fuse 80 is shared by the two cooking modes, which not only ensures the safety, but also reduces the number of components, simplifies the safety protection structure, and reduces the production cost.

[0053] According to the cooking appliance 100 of the embodiment of the present application, the fuse 80 is fused at the preset temperature, which has an effective safety protection effect and high reliability. Moreover, the fuse 80 is shared by the first cooking mode and the second cooking mode, which simplifies the safety protection structure and reduces the cost of the cooking appliance 100.

[0054] According to some embodiments of the present application, the contact temperature of the fuse 80 in the first cooking mode and the second cooking mode can be basically the same by reasonably arranging the position of the fuse 80 and adjusting the power of the heating assembly 20 in the first cooking mode and the second cooking mode, so that the single fuse 80 ensures the safety performance of the two cooking modes.

[0055] Specifically, as shown in Figure 1 , Figure 9 and Figure 10 , the heating assembly 20 can include a first heating member 21 and a second heating member 22, and the distance between the fuse 80 and the first heating member 21 is less than the distance between the fuse 80 and the second heating member 22, so that the first heating member 21 radiates more heat around the fuse 80 than the second heating member 22 at the same heating power. In addition, in the first cooking mode, the heating power of the first heating member 21 is P1, and the second heating member 22 stops heating; in the second cooking mode, the heating power of the first heating member 21 is P2, and the heating power of the second heating member 22 is P3. Wherein, P1>P2.

[0056] Thus, in the first cooking mode, the fuse 80 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 80 is too high, the contact temperature of the fuse 80 is too high, and the fuse 80 is fused. In the second cooking mode, the fuse 80 is simultaneously 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 80 in the second cooking mode is basically the same as the heat radiated by the first heating element 21 around the fuse 80 in the first cooking mode, and the safety protection of the single fuse 80 is realized.

[0057] In some embodiments, the heating powers P1 and P2 satisfy: 0.3≤P2 / P1≤0.7, so that the contact temperature of the fuse 80 in the first cooking mode and the second cooking mode is closer, and the safety protection effect of the single fuse 80 in the two cooking modes is improved.

[0058] In some embodiments, the heating powers P1, P2 and P3 satisfy: P2+P3>P1, so that in the second cooking mode, the heat radiated by the first heating element 21 to the fuse 80 is still closer to the heat radiated by the first heating element 21 to the fuse 80 in the first cooking mode when the second heating element 22 is far away from the fuse 80, that is, the contact temperature of the fuse 80 in the two cooking modes is closer, and the safety protection effect of the single fuse 80 in the two cooking modes is improved.

[0059] In some embodiments, the heating powers P1, P2 and P3 satisfy: 500W≤P1≤1100W, 300W≤P2≤900W, and 700W≤P3≤1300W. In the above heating power range, the normal and efficient cooking of the food material in the first cooking mode and the second cooking mode is ensured, the cooking efficiency and the cooking effect are ensured, and the heat radiated by the heating assembly 20 to the fuse 80 in the two cooking modes is the same, so that the safety protection effect of the single fuse 80 is more accurate.

[0060] For example, in some specific embodiments, the fuse 80 has a fuse temperature of 300℃, the first heating element 21 has a heating power of 1000W in the first cooking mode, and the second heating element 22 stops heating; in the second cooking mode, the first heating element 21 has a heating power of 600W, and the second heating element 22 has a heating power of 1200W.

[0061] According to some embodiments of the present application, as Figure 1As shown, the fuse 80 and the second heating element 22 are both arranged below the first heating element 21, and the second heating element 22 is arranged around the fuse 80, in other words, the fuse 80 is located in the region surrounded by the second heating element 22, which is conducive to making the contact temperature of the fuse 80 closer to the equivalent heating temperature of the heating assembly 20, and the arrangement of the heating assembly 20 and the fuse 80 is more compact.

[0062] In some specific embodiments, continuing to refer to Figure 1 As shown, the first heating element 21 is a ring-shaped heating disc, and the fuse 80 is arranged adjacent to the inner periphery of the ring-shaped heating disc, in other words, in the radial direction of the ring-shaped heating disc, the distance between the fuse 80 and the inner periphery of the ring-shaped heating disc is smaller than the distance between the fuse 80 and the outer periphery. The second heating element 22 is a ring-shaped heating tube, and the ring-shaped heating tube is arranged adjacent to the outer periphery of the ring-shaped heating disc, in other words, in the radial direction of the ring-shaped heating disc, the distance between the ring-shaped heating tube and the inner periphery of the ring-shaped heating disc is greater than the distance between the ring-shaped heating tube and the outer periphery. Thus, the distance between the fuse 80 and the ring-shaped heating tube is greater than the distance between the fuse 80 and the ring-shaped heating disc, and the fuse 80 is adjacent to the lower surface of the ring-shaped heating disc, so that the ring-shaped heating disc can directly radiate heat to the fuse 80, thereby improving the safety protection reliability.

[0063] According to some embodiments of the present application, as Figures 1-8 As shown, the food container 40 can include a first food container 41 and a second food container 42, and the first food container 41 and the second food container 42 are placed in the pot assembly 10 alternatively. And when different food containers 40 are matched with the pot assembly 10, the cooking appliance 100 can work in different cooking modes to achieve different cooking functions. By changing the type of the food container 40 matched with the pot assembly 10, the cooking appliance 100 can work in different cooking modes, so that the cooking appliance 100 can meet more cooking demands and achieve different cooking effects.

[0064] In some specific embodiments, as Figures 1-3 As shown, the cooking appliance 100 can have a first cooking mode and a second cooking mode, and the food container 40 can include a first food container 41 and a second food container 42. In the state that the first food container 41 is placed in the pot assembly 10, the cooking appliance 100 can be in the first cooking mode; and in the state that the second food container 42 is placed in the pot assembly 10, the cooking appliance 100 can be in the second cooking mode.

[0065] 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.

[0066] In addition, as Figures 1-8As shown, the cooking utensil 100 can further 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 food container 40 placed in the pot assembly 10, and the control assembly can control the cooking mode of the cooking utensil 100 according to the detection result of the detection assembly 70, i.e., according to the type of the food container 40 currently placed in the pot assembly 10.

[0067] In this way, after the user fits the required food container 40 to the pot assembly 10, the cooking utensil 100 can automatically control the cooking utensil 100 to work according to 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 utensil 100 cannot work normally or the food container 40 is damaged. For example, the user uses a basket and cover for air frying, but selects a pressure cooking mode, which can cause the cooking utensil 100 to fail to work normally.

[0068] In the embodiment 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 assembly 10 is the first food container 41, the control assembly can control the cooking utensil 100 to be in the first cooking mode; and when the detection assembly 70 detects that the food container 40 placed in the pot assembly 10 is the second food container 42, the control assembly can control the cooking utensil 100 to be in the second cooking mode. In this way, the automatic selection and switching of the first cooking mode and the second cooking mode are realized.

[0069] According to some embodiments of the present application, as shown in Figures 1-8 As shown, the cover assembly 60 can include the first cover assembly 61 and the second cover assembly 62, which are alternatively covered on the pot assembly 10. Moreover, when different cover assemblies 60 are fitted to the pot assembly 10, the cooking utensil 100 can work in different cooking modes to realize different cooking functions. The cooking utensil 100 works in different cooking modes by changing the type of the cover assembly 60 fitted to the pot assembly 10.

[0070] In some specific embodiments, as shown in Figures 1-3 As shown, the cooking utensil 100 can have the first cooking mode and the second cooking mode, and the plurality of cover assemblies 60 can include the first cover assembly 61 and the second cover assembly 62. In the state that the first cover assembly 61 is covered on the pot assembly 10, the cooking utensil 100 can be in the first cooking mode; and in the state that the second cover assembly 62 is covered on the pot assembly 10, the cooking utensil 100 can be in the second cooking mode.

[0071] Of course, the plurality of cover assemblies 60 can further include a third cover assembly and a fourth cover assembly, and the corresponding cooking utensil 100 can further have a third cooking mode and a fourth cooking mode, which are all within the protection scope of the present application.

[0072] In the embodiment in which the cooking utensil 100 includes the detection assembly 70 and the control assembly, as shown in Figure 11 the detection assembly 70 can be of the type of the cover assembly 60 of the pot assembly 10, and the control assembly can control the cooking mode of the cooking utensil 100 according to the detection result of the detection assembly 70, i.e., according to the type of the current cover assembly 60.

[0073] Therefore, after the user matches the required cover assembly 60 to the pot assembly 10, the cooking utensil 100 can automatically control the cooking utensil 100 to work according to the cover assembly 60 used by the user, without the user manually selecting the cooking mode, which simplifies the user operation steps and is more convenient to use. Moreover, it avoids the situation that the cooking mode selected by the user does not match the type of the cover assembly 60 used, which leads to the cooking utensil 100 unable to work normally or the cover assembly 60 being damaged.

[0074] In the embodiment in which the plurality of cover assemblies 60 includes the first cover assembly 61 and the second cover assembly 62, when the detection assembly 70 detects that the cover assembly 60 covered on the pot assembly 10 is the first cover assembly 61, the control assembly can control the cooking utensil 100 to be in the first cooking mode; and when the detection assembly 70 detects that the cover assembly 60 covered on the pot assembly 10 is the second cover assembly 62, the control assembly can control the cooking utensil 100 to be in the second cooking mode. Therefore, the automatic selection and switching of the first cooking mode and the second cooking mode are realized.

[0075] In some specific embodiments, the detection assembly 70 can simultaneously detect the type of the cover assembly 60 covered on the pot assembly 10 and the type of the food container 40 placed in the pot assembly 10, and the control assembly simultaneously controls the cooking mode of the cooking utensil 100 according to the types of the current cover assembly 60 and the food container 40.

[0076] The specific structure and arrangement structure of the detection assembly 70 according to some embodiments of the present application will be described below in combination with the accompanying drawings.

[0077] According to some embodiments of the present application, as shown in Figures 1-3 and Figure 11As shown, the detection assembly 70 can include a cover detection portion 71 provided on the pot body assembly 10, and the second cover assembly 62 can be provided with a cover detection matching portion 72. The cover detection portion 71 is configured to detect the cover detection matching portion 72. When the second cover assembly 62 is provided on the pot body assembly 10, the cover detection matching portion 72 is within the detection range of the cover detection portion 71, so that the cover detection portion 71 can detect the cover detection matching portion 72. When the second cover assembly 62 is not provided on the pot body assembly 10 and the first cover assembly 61 is provided on the pot body assembly 10, the cover detection matching portion 72 is out of the detection range of the cover detection portion 71, so that the cover detection portion 71 cannot detect the cover detection matching portion 72. Thus, when the cover detection portion 71 detects the cover detection matching portion 72, it can be determined that the second cover assembly 62 is provided on the pot body assembly 10; when the cover detection portion 71 does not detect the cover detection matching portion 72, it can be determined that the first cover assembly 61 is provided on the pot body assembly 10. The type of the cover assembly 60 is identified by whether the cover detection portion 71 can detect the cover detection matching portion 72, only one cover detection matching portion 72 is needed, and the detection logic of the cover detection portion 71 is simple, which simplifies the structure of the detection assembly 70 and reduces the cost.

[0078] Of course, according to the above description, the technical solution that the first cover assembly 61 is provided with the cover detection matching portion 72 and the second cover assembly 62 is not provided with the cover detection matching portion 72 is understandable to those skilled in the art.

[0079] In some embodiments, as shown in Figure 2 The cover detection portion 71 can be a dry reed, and the cover detection matching portion 72 can be a magnetic piece. When the second cover assembly 62 is provided on the pot body assembly 10, the magnetic piece is within the detection range of the dry reed, a feedback detection is formed, 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 cover assembly 61 is provided on the pot body assembly 10, the dry reed is turned off, and the control assembly controls the cooking appliance 100 to be in the first cooking mode.

[0080] In some examples, as shown in Figure 2 The pot body assembly 10 can include a housing 11, an outer pot 12, and a housing cover, the outer pot 12 is provided in the housing 11, and the housing cover is provided on the top of the housing 11. The cover detection portion 71 can be embedded in the housing cover and connected with the control assembly through a lead wire between the housing 11 and the outer pot 12. The outer edge of the second cover assembly 62 is supported on the housing cover, and the cover detection matching portion 72 can be embedded in the outer edge of the second cover assembly 62, so that when the second cover assembly 62 is provided on the pot body assembly 10, the cover detection matching portion 72 is above the cover detection portion 71, which is beneficial to improve the detection sensitivity.

[0081] In some embodiments, the cover detection matching portion 72 can be a transmitting end for transmitting an electrical signal or an optical signal, and the cover detection portion 71 can be a receiving end for receiving the electrical signal or the optical signal transmitted by the cover detection matching portion 72. When the cover detection portion 71 receives the electrical signal or the optical signal, the control assembly controls the cooking appliance 100 to be in the second cooking mode; when the cover detection portion 71 does not receive the electrical signal or the optical signal, the control assembly controls the cooking appliance 100 to be in the first cooking mode.

[0082] Of course, the specific structure of the cover detection portion 71 and the cover detection matching portion 72 includes but is not limited to the above, as long as it can meet the requirement of detecting the type of the cover assembly 60 provided on the pot assembly 10.

[0083] According to some other embodiments of the present application, as shown in Figures 4-8 and Figure 12 The plurality of food containers 40 includes a first food container 41 and a second food container 42, and the detection assembly 70 can include two signal transceiving assemblies 73, both of which are provided on the pot assembly 10. The signal on-off state of the two signal transceiving assemblies 73 can be used to determine the type of the food container 40 placed on the pot assembly 10.

[0084] For example, in some embodiments, when the second food container 42 is placed on the pot assembly 10, the second food container 42 can block the transmitting portion 731 and the receiving portion 732 of one of the two signal transceiving assemblies 73, so that the signal of one of the two signal transceiving assemblies 73 is disconnected, while the signal of the other signal transceiving assembly 73 is connected; when the first food container 41 is placed on the pot assembly 10, the first food container 41 can block the transmitting portion 731 and the receiving portion 732 of both of the two signal transceiving assemblies 73, so that the signals of both of the two signal transceiving assemblies 73 are disconnected.

[0085] Therefore, when only one of the two signal transceiving assemblies 73 is connected, it is determined that the second food container 42 is placed on the pot assembly 10, and when both of the two signal transceiving assemblies 73 are disconnected, it is determined that the first food container 41 is placed on the pot assembly 10.

[0086] In addition, as shown in Figure 12 when both of the two signal transceiving assemblies 73 are connected, it is determined that no food container 40 is placed on the pot assembly 10, and the control assembly can control the reminding assembly of the cooking appliance 100 to send a container placement reminding information.

[0087] In some embodiments, as shown in Figure 4 and Figure 7As shown, the pot body assembly 10 has a containing cavity 101, and the food container 40 can be placed in the containing cavity 101. The signal transceiver assembly 73 can include a transmitting portion 731 and a receiving portion 732, which are oppositely arranged on the cavity wall of the containing cavity 101. The transmitting portion 731 can emit a signal (e.g. an optical signal), and the receiving portion 732 can receive the signal emitted by the transmitting portion 731 after the signal passes through the containing cavity 101, so that the signal transceiver assembly 73 is in a signal-on state. If the signal is blocked by a component in the containing cavity 101, the receiving portion 732 cannot receive the signal emitted by the transmitting portion 731, and at this time, the signal transceiver assembly 73 is in a signal-off state. Therefore, by oppositely arranging the transmitting portion 731 and the receiving portion 732 on the cavity wall of the containing cavity 101, the blocking states of the different food containers 40 to the transmitting portion 731 and the receiving portion 732 are different when different food containers 40 are used, so that the signal-on and signal-off states of the two signal transceiver assemblies 73 are different, the detection mode of the detection assembly 70 is simple and accurate, and misjudgment is not easy.

[0088] In some embodiments, as shown in Figures 4-8 The containing cavity 101 is provided with a support for supporting the food container 40 placed in the containing cavity 101. The transmitting portion 731 and the receiving portion 732 can be arranged on the side wall of the containing cavity 101. The longitudinal distances between the two signal transceiver assemblies 73 and the support are L1 and L2, respectively, that is, the two signal transceiver assemblies 73 are arranged on the side wall of the containing cavity 101 in a longitudinal direction. The height of the first food container 41 is L3, and the height of the second food container 42 is L4. Among them, L1 < L4 < L2 < L3.

[0089] Therefore, as shown in Figures 4-6 When the second food container 42 is placed in the containing cavity 101, the top of the second food container 42 is located between the two signal transceiver assemblies 73, so that the second food container 42 can block the transmitting portion 731 and the receiving portion 732 of the signal transceiver assembly 73 with a lower height, so that the signal transceiver assembly 73 is in a signal-off state, and the transmitting portion 731 and the receiving portion 732 of the signal transceiver assembly 73 with a higher height can be in a signal-on state. As shown in Figure 7 and Figure 8 When the first food container 41 is placed in the containing cavity 101, the top of the first food container 41 is higher than the two signal transceiver assemblies 73, so that the first food container 41 can block the transmitting portion 731 and the receiving portion 732 of the two signal transceiver assemblies 73 at the same time, so that the two signal transceiver assemblies 73 are in a signal-off state at the same time.

[0090] According to some embodiments of the present application, as shown in Figure 5 and Figure 6As shown, the pot assembly 10 can include a housing 11 and an outer pot 12, and the outer pot 12 is arranged in the housing 11. The side wall of the outer pot 12 can be provided with a first through hole 121 and a second through hole 122 arranged oppositely, the emitting part 731 is located between the housing 11 and the outer pot 12 and opposite to the first through hole 121, and the receiving part 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 emitting part 731 can pass through the first through hole 121, the accommodating cavity 101 and the second through hole 122 in sequence to propagate to the receiving part 732. The housing 11 and the outer pot 12 can protect the emitting part 731 and the receiving part 732, so as to avoid the signal transceiver assembly 73 from being damaged or contaminated and affecting the detection effect.

[0091] It should be noted that in the embodiment provided with two signal transceiver assemblies 73, the emitting parts 731 of the two signal transceiver assemblies 73 can be opposite to the same first through hole 121, or can be arranged opposite to two first through holes 121 respectively, and the two receiving parts 732 can be opposite to the same second through hole 122, or can be arranged opposite to two second through holes 122 respectively.

[0092] Of course, according to the above description, the technical solution that only one signal transceiver assembly 73 is signal-conducted when the first food container 41 is placed in the pot assembly 10, and two signal transceiver assemblies 73 are signal-disconnected at the same time when the second food container 42 is placed in the pot assembly 10, is understandable to those skilled in the art.

[0093] According to some embodiments of the present application, as shown in the accompanying drawings, Figures 1-8 As shown, the cooking utensil 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 for directly conducting heat to the food container 40 placed in the pot assembly 10, or indirectly heating the food container 40 by heating air, so as to realize the cooking of the food in the food container 40. In some embodiments, the heating assembly 20 can be arranged in the accommodating 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 second cover assembly 62, and the air fan assembly 30 can drive the air flow in the pot assembly 10. For example, when the second food container 42 is placed in the pot assembly 10, the air heated by the heating assembly 20 can be fully contacted with the food material in the second food container 42 by the driving of the air fan assembly 30, so as to improve the uniformity of the coloring of the food material.

[0094] In some embodiments, when the first food container 41 is placed in the accommodating cavity 101, the first cooking cavity 411 of the first food container 41 is not in communication with the accommodating cavity 101 (i.e., 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 the first food container 41 and heat the food in the first cooking cavity 411.

[0095] In some embodiments, the first food container 41 can be attached to the heating assembly 20, i.e., 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 heating of the food in the first cooking cavity 411.

[0096] In some embodiments, when the second food container 42 is placed in the accommodating cavity 101, an air duct 423 is defined between the second food container 42 and the pot assembly 10, and the second food container 42 can be provided with an air passing hole 422 that is in communication with the air duct 423 and the second cooking cavity 421 (i.e., the cooking cavity of the second food container 42, hereinafter referred to as the second cooking cavity 421) of the second food container 42, for example, at least one of the top wall and the side wall of the second food container 42 can be provided with the air passing hole 422, or the top opening of the second food container 42 can be formed as the air passing hole 422 and be in communication with the accommodating cavity 101. Under the driving of the fan assembly 30, the air heated by the heating assembly 20 can 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 conduction mode of the first food container 41, the mode of directly heating the food by hot air can improve the dehydration and coloring effect of the food and achieve different cooking functions.

[0097] In addition, in some embodiments, the bottom wall of the second food container 42 is spaced apart from the bottom wall of the accommodating 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 accommodating cavity 101 by a certain gap, so that the air duct 423 is formed between the second food container 42 and the cavity wall of the accommodating cavity 101. By providing the air duct 423, the air flow resistance is reduced, the air can fully circulate in the air duct 423 and the second cooking cavity 421, and the uniformity and efficiency of heating of the food are improved.

[0098] In some specific embodiments, as Figure 1 and Figure 4As shown, the bottom wall of the second food container 42 is provided with an air passing hole 422, and an air duct 423 is formed between the second food container 42 and the cavity wall of the accommodating cavity 101. Under the driving of the fan assembly 30, the air in the air duct 423 can enter the second cooking cavity 421 through the air passing hole 422, and then return to the air duct 423 through the top opening of the second cooking cavity 421, or 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 passing hole 422, thereby realizing the circulating flow of the air. The air passing hole 422 and the top opening of the second cooking cavity 421 are oppositely arranged, so that the air can flow through a larger range of the second cooking cavity 421, and the uniformity of the heating of the food in each region is improved.

[0099] In some other embodiments, the side wall of the second food container 42 is provided with air passing holes 422, and at least two air passing holes 422 are oppositely arranged (for example, some air passing holes 422 are arranged on the left side of the second cooking cavity 421, and some air passing holes 422 are arranged on the right side of the second cooking cavity 421). The air in the air duct 423 can enter and exit the second cooking cavity 421 through the oppositely arranged air passing holes 422, so that the food in each region in the second cooking cavity 421 is uniformly heated.

[0100] In some embodiments of the fan assembly 30 including a fan, the fan can be oppositely arranged with the air passing hole 422, or the fan can be oppositely arranged with the top opening of the second cooking cavity 421, so as to improve the efficiency of the air entering and exiting the second cooking cavity 421 through the air passing hole 422 or the top opening, thereby improving the effect of the circulating flow of the air.

[0101] 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.

[0102] In some embodiments of the present application, as shown in Figure 1 and Figure 4 As shown, the fan assembly 30 can be mounted at the bottom of the pot body assembly 10. The fan assembly 30 can form a positive pressure or a negative pressure in the air duct 423 located at the lower part of the accommodating cavity 101, so as to flow the air in the entire air duct 423 and make the air enter and exit the second cooking cavity 421. The mounting space at the bottom of the pot body assembly 10 is larger, 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 accommodating 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. The air heated by the heating assembly 20 can flow rapidly to the low-temperature region, which is beneficial to improve the uniformity of the temperature in the accommodating cavity 101 and the second cooking cavity 421.

[0103] In some embodiments of the present invention, the fan assembly 30 can be installed on the side of the pot body assembly 10. The operation of the fan assembly 30 can create positive or negative pressure in the air duct 423 located on the side of the receiving cavity 101, thereby causing air to flow throughout the air duct 423 and into and out of the second cooking cavity 421. Driving the airflow within the receiving cavity 101 from the side of the receiving cavity 101 facilitates faster air circulation in the upper and lower parts of the receiving cavity 101, improving the temperature uniformity within the receiving cavity 101 and the second cooking cavity 421. In embodiments where the heating assembly 20 is located at the lower part of the receiving cavity 101, the upper part of the receiving cavity 101 is farther from the heating assembly 20, and the fan assembly 30 is positioned vertically between the heating assembly 20 and the top of the receiving cavity 101, which facilitates the upward flow of hot air from the lower part of the receiving cavity 101.

[0104] In some embodiments of the cooking appliance 100 that include a second cover assembly 62, a fan assembly 30 may be disposed on the second cover assembly 62 to drive airflow within the receiving cavity 101 from the upper part of the receiving cavity 101 and to the second cooking cavity 421. In embodiments where the heating assembly 20 is disposed at the lower part of the receiving cavity 101, the fan assembly 30 can create positive or negative pressure in areas farther from the heating assembly 20 to accelerate the flow of hot air from areas closer to the heating assembly 20 to low-temperature areas, thereby achieving temperature uniformity within the receiving cavity 101 and the second cooking cavity 421.

[0105] The heating assembly 20 according to some embodiments of the present invention is described below with reference to the accompanying drawings.

[0106] According to some embodiments of the present invention, the heating assembly 20 may include a first heating element 21. The first heating element 21 operates in both a first cooking mode and a second cooking mode of the cooking appliance 100. Heating through the same heating element in both cooking modes helps to reduce the number of components and lower costs.

[0107] According to some embodiments of the present invention, such as Figure 1 and Figure 3 As shown, the heating assembly 20 may include two heating elements, namely a first heating element 21 and a second heating element 22. The second heating element 22 is located below the first heating element 21. In the first cooking mode, the first heating element 21 is operational, but the second heating element 22 is inactive; in the second cooking mode, both the first and second heating elements are operational. In other words, the first heating element 21 is used in both the first and second cooking modes. In the second cooking mode, heating with both heating elements further increases the surface area in contact with air, thereby further improving the air frying effect.

[0108] It should be noted that the working of the first heating member 21 and the working of the second heating member 22 are to be understood in a broad sense. That is, the first heating member 21 and the second heating member 22 can work simultaneously, alternately, or staggeredly, and the like, as long as the first heating member 21 and the second heating member 22 can heat the air in the containing cavity 101 in the second cooking mode.

[0109] In the embodiments of the present application, the first heating member 21 can be a combination of a hot plate or IH, and the second heating member 22 can be a heat pipe, infrared, or a hot plate. The first heating member 21 and the second heating member 22 can be a combination of any two heating modes.

[0110] In some embodiments of the present application, as shown in Figure 1 and Figure 3 , the heating assembly 20 is located at the lower part of the containing cavity 101. When the food container 40 (the first food container 41 or the second food container 42) is placed in the containing 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 containing cavity 101, as shown in Figure 3 , 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 containing 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 containing cavity 101 heated by the heating assembly 20 has a natural upward tendency, which is conducive to improving the internal heat field circulation and achieving the uniformity of the heat received by the food.

[0111] 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. 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 practicality.

[0112] 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, and the like, and the food cooking efficiency is high, and the nutrient extraction effect is better.

[0113] 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 baking, frying, air-frying and other treatments of the food, so that the food is uniformly heated and the baking effect is good.

[0114] In the embodiments of the present application, since the heating assembly 20 provided on the pot assembly 10 is used for heating in the first cooking mode and the second cooking mode, the heating structure does not need to be provided 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, the heating assembly 20 is used for heating, which realizes the under placement of the heat source and is beneficial to more uniform coloring of the food.

[0115] In the embodiments including the first cover assembly 61 and the first cooking mode being the pressure cooking mode, as shown in Figure 3 the first cover assembly 61 can close the top opening of the first food container 41 to make the first cooking cavity 411 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. For example, the first cover assembly 61 can include a cover body, an exhaust valve 611 and a sealing ring. The sealing ring is mounted on the cover body and sealingly matches 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 provided 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.

[0116] In the embodiments 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 the cooking mode is switched, and the user operation is simpler. For example, the cooking appliance 100 can only include the first cover assembly 61, and the first cover assembly 61 is provided 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, and the circulation flow of the hot air is facilitated.

[0117] In the embodiments including the second cover assembly 62, as shown in Figure 1 the second cover assembly 62 can also have a transparent area 621. The user can check the cooking state of the food in the second cooking cavity 421 through the transparent area 621 at any time, which is beneficial to the observation of the user, facilitates the user to master the cooking degree of the food, and improves the user experience. Specifically, as shown in Figure 1As shown, the second cover assembly 62 may include a cover plate and a handle. The handle is connected to the cover plate to facilitate the removal and placement of the second cover assembly 62. The cover plate may be a transparent glass plate for easy observation by the user.

[0118] like Figure 11 and Figure 12 As shown, according to an embodiment of the present invention, the control method of a cooking appliance 100 includes a heating assembly 20 and a fuse 80. The heating assembly 20 includes a first heating element 21 and a second heating element 22. The distance between the fuse 80 and the first heating element 21 is less than the distance between the fuse 80 and the second heating element 22. The control method includes:

[0119] S1: In the first cooking mode, the heating power of the first heating element 21 is controlled to P1, and the second heating element 22 stops heating;

[0120] S2: In the second cooking mode, the heating power of the first heating element 21 is controlled to be P2, and the heating power of the second heating element 22 is controlled to be P3, where P1 > P2.

[0121] According to the embodiments of the present invention, the cooking appliance 100 adjusts the power of the heating component 20 in the first cooking mode and the second cooking mode, so that the contact temperature of the fuse 80 is basically the same in the two cooking modes, and it can melt at the basically the same preset temperature, so as to achieve effective safety protection and high reliability. It realizes the sharing of the fuse 80 in the first cooking mode and the second cooking mode, and achieves the goal of ensuring the safety performance of the two cooking modes with a single fuse 80, which simplifies the safety protection structure and reduces the cost of the cooking appliance 100.

[0122] According to some embodiments of the present invention, the heating powers P1 and P2 satisfy: 0.3≤P2 / P1≤0.7, so that the contact temperature of the fuse 80 in the first cooking mode and the second cooking mode is closer, which is more conducive to improving the safety protection effect of the single fuse 80 in the two cooking modes.

[0123] In some embodiments, the heating powers P1, P2, and P3 satisfy: P2 + P3 > P1, so that even when the second heating element 22 is far from the fuse 80, the heat radiated to the fuse 80 in the second cooking mode in conjunction with the first heating element 21 is still closer to the heat radiated to the fuse 80 by the first heating element 21 in the first cooking mode. That is, the contact temperature of the fuse 80 is closer in the two cooking modes, which is more conducive to improving the safety protection effect of the single fuse 80 in the two cooking modes.

[0124] In some embodiments, the heating powers P1, P2 and P3 satisfy: 500W≤P1≤1100W, 300W≤P2≤900W, 700W≤P3≤1300W. Within the above heating power ranges, the normal and efficient cooking of the food material in the first and second cooking modes is ensured, the cooking efficiency and effect are ensured, and the heat radiated by the heating assembly 20 as a whole to the fuse 80 is the same in the two cooking modes, achieving more accurate single-fuse 80 safety protection effect.

[0125] For example, in some specific embodiments, the fusing temperature of the fuse 80 is 300℃, in the first cooking mode, the heating power of the first heating piece 21 is 1000W, and the second heating piece 22 stops heating; in the second cooking mode, the heating power of the first heating piece 21 is 600W, and the heating power of the second heating piece 22 is 1200W.

[0126] The cooking appliance 100 according to the embodiments of the present application can adopt the control method of the cooking appliance 100 according to the embodiments of the present application, and all the features of the cooking appliance 100 according to the embodiments of the present application are introduced into the control method of the cooking appliance 100 according to the embodiments of the present application, and the specific operation, structure and advantages will not be described here.

[0127] Other structures and operations of the cooking appliance 100 according to the embodiments of the present application are known to those skilled in the art, and will not be described in detail here.
