Description

[0001] The technical field of the invention is the kitchen appliance field, in particular a cooking appliance with a heating assembly in the lid. BACKGROUND Various cooking appliances with a heating assembly in the lid are known in the art, in particular air fryers and multi-cookers with air fryer or baking functions. Typically, the heating assembly comprises a heating device and a fan, which heats air with the heating device and blows the heated air towards the food in the pot for cooking purposes. The food is usually placed in a movable basket or inner pot in the pot body. Some inner pots have a handle for holding the inner pot for moving. When the cooking appliance is working, the handle is wrapped between the lid assembly and the pot body. In this way, the heat absorbed by the handle cannot be dissipated naturally, and the surface of the handle quickly warms up, which can cause a safety hazard. CONTENT OF THE INVENTION The object of the invention is to provide a cooking appliance that solves the problem of the excessively high temperature of the handle. To this end, the invention proposes a cooking appliance comprising a pot assembly and a lid assembly covering the pot assembly, wherein the pot assembly comprises a housing and an inner pot placed in the housing, and the lid assembly comprises an outer lid, an inner lid and an air heating assembly, characterized in that:

[0002] - the inner pot is provided with a handle for resting along the housing;

[0003] - the air heating assembly comprises a driving device and an upper fan in a first space defined between the outer lid and the inner lid, and a lower fan and a heating device in a second space defined between the inner lid and the inner pot;

[0004] - The outer cover is provided with an air guide channel, and the air guide channel passes through a position on the side wall of the outer cover corresponding to the portion of the handle of the inner pot to guide the cold air sucked in by the upper fan to the handle of the inner pot. The inner pot according to the application is provided with a handle, and the inner pot can be conveniently held and moved. The handle is designed to be placed on the outer shell, and thus the space between the outer shell and the inner pot is not occupied, and thus the volume of the inner pot can be increased, and the cooking efficiency is improved. However, when the cooking appliance is working, the handle of the inner pot is clamped between the pot body shell and the cover assembly, and thus the heat absorbed by the handle from the inner pot cannot be quickly dissipated, and the handle is overheated too quickly, which exceeds the requirements of safety regulations. Therefore, the cover assembly of the application is provided with an upper fan and an air guide channel for blowing cold air to the handle to reduce the temperature. The upper fan sucks the room temperature air outside the cooking appliance, is used for cooling the elements in the first space, avoids the risk of overheating, and flows out of the air guide channel of the outer cover and is guided to the handle of the inner pot under the action of the upper fan. In addition, the upper fan and the lower fan can be driven by the driving device, and the two work at the same time, and the room temperature air sucked by the upper fan can continuously reach the handle of the inner pot during the working period of the cooking appliance, and the handle is cooled to prevent the handle from being overheated and having a high temperature. In the following, "room temperature air" and "cold air" are used without distinction. Preferably, the air guide channel includes an air outlet provided in the side wall of the outer cover, and a guide fin provided in the inner cover and / or a guide cover provided outside the side wall of the outer cover. In fact, after the cold air is sucked in by the upper fan, it flows in the first space defined between the outer cover and the inner cover, and the air guide channel is part of the flow path. The air outlet can be provided only on the portion of the side wall of the outer cover corresponding to the handle of the inner pot, so that the cold air can flow out of the air outlet. More preferably, a guide fin can be provided inside the outer cover to guide the cold air to the air outlet or make the cold air flow to the air outlet more concentrated. Alternatively or additionally, a guide cover can be provided outside the side wall of the outer cover to guide the cold air flowing out of the air outlet to the handle of the inner pot or prevent it from diffusing to useless areas. It can be understood that these features can improve the cooling efficiency of the handle. Preferably, the guide fin is arranged downstream of the air outlet in the direction of the air flow generated by the upper fan to block the air flow generated by the upper fan.It can be understood that the upper fan is driven to rotate around the shaft by the driving device, so as to drive the cold air sucked into the first space to also move in the circumferential direction. The air guide ribs are arranged downstream of the air outlet along the airflow direction, which can block part of the airflow from continuing to move in the circumferential direction, so that more cold air flows to the air outlet, which can improve the cooling efficiency of the handle. Preferably, the outer cover is provided with a cold air inlet above, and the outer cover side wall is also provided with an additional outlet. Specifically, for example, the outer cover is provided with an opening above, and an air inlet and an air inlet cover are installed, and the cold air inlet is formed between the two, for example, in the form of multiple gap openings. Under the action of the rotation of the upper fan, the room temperature air enters the first space from the gap openings and forms a whirlwind, so as to cool the elements located in the cover assembly. Then, the cold air flows out from the air outlet provided in the outer cover side wall, which also cools the inner pot handle. The additional outlet is beneficial to the faster flow of cold air out of the outer cover, which can speed up the speed of air circulation and improve the cooling efficiency. Preferably, the handle comprises a through hole, so that the cold air blown out from the air guide channel can pass through the through hole to reach the lower surface of the handle. In this way, the upper and lower surfaces of the handle can be cooled at the same time, and the inner pot is also convenient to hold. Preferably, the handle is a thin shell structure. The thin shell structure is beneficial to heat dissipation. Preferably, the inner cover is a heat insulation cover. The inner cover separates the first space from the cooking space, which can prevent the heat generated by the heating device from entering the first space and causing improper heating of the elements arranged therein, thereby causing safety hazards. The other features and advantages of the present application will become more apparent from the following description of the preferred embodiments provided as simple examples and not limiting, and the accompanying drawings, in which:On the contrary, they are merely examples of devices, systems, apparatuses, and methods consistent with some aspects of the present invention. Fig. 1 shows a cooking appliance 1, in this case a multi-cooker, in particular a multi-cooker comprising a baking function or an air-frying function, according to a preferred embodiment of the present invention. In particular, the cooking appliance 1 comprises a cooker assembly 2 and a lid assembly 3 which can be closed on the cooker assembly 2. As shown in Fig. 1, the lid assembly 3 is arranged at one end of the cooker assembly 2. The cooker assembly 2 comprises an outer shell 20 and an inner cooker 22 which is movably arranged in the outer shell. The cooker assembly 2 can also comprise a plurality of inner cookers which are replaceable with each other. As shown in Fig. 3, the inner cooker 22 can be provided with a movable grill 220. Radially opposite outer walls of the inner cooker 22 are provided with handles 24. As shown in Fig. 1, the outer shell 20 is correspondingly provided with handle supporting portions 26. By supporting the handles 24 by means of the handle supporting portions 26, the inner cooker 22 is rested on the upper edge of the outer shell 20. In a preferred embodiment, the handle supporting portions 26 comprise longitudinal gaps provided in the upper edge of the outer shell 20, so that when the handles 24 of the inner cooker 22 are placed thereon, the upper edge of the inner cooker 22 is only slightly higher than the upper edge of the outer shell 20. In addition, the handle supporting portions 26 can also comprise protruding grooves provided on the outer wall of the outer shell 20, which accommodate the handles 24, so that the cooking appliance 1 is more beautiful when the lid assembly 2 is closed. The lid assembly 3 comprises an outer lid 30, an inner lid 32 and an air heating assembly 4. As shown in Fig. 3, the outer lid 30 comprises an opening 310 at the top. As shown in Fig. 2, an air inlet cover seat 311 and an air inlet cover 312 are mounted in the opening 310, and the gap between the two forms a cold air inlet 31. In the illustrated embodiment, the cold air inlet 31 is arranged around the air inlet cover 312. The space defined between the outer lid 30 and the inner lid 32 is called a first space, and a driving device 40 and an upper fan 42 of the air heating assembly 4 are arranged in the first space. The space defined between the inner lid 32 and the inner cooker 22 is called a second space, and a lower fan 44 and a heating device 46 of the air heating assembly 4 are arranged in the second space. The driving device 40 is, for example, an electric motor and is fixed in the inner lid 30 in a known manner, for example by providing a supporting seat. The driving device 40 comprises a driving shaft (not shown) which directly or indirectly drives the upper fan 42 to rotate, and the driving shaft also passes through the inner lid 32 to directly or indirectly drive the lower fan 44 to rotate.When the upper fan 42 rotates, room temperature air is drawn from the air inlet 31 into the first space to cool the elements therein, and then flows out from the air outlet 62 to cool the handle. When the lower fan 44 rotates, air for heating is drawn from another air inlet (not shown in the drawings) into the second space to participate in cooking. The air paths for cooling and for heating are independent of each other and do not interfere with each other. Preferably, the inner cover 32 is a heat-insulating cover. The inner cover 32 separates the first space from the cooking space, especially the heating device 46, so that heat generated by the heating device 46 can be prevented from entering the first space to cause undue heating of the elements arranged therein and to cause a safety hazard. Preferably, as shown in FIGS. 1 and 2, the cover assembly 4 can further include a protective cover 48 arranged below the heating device 46 to prevent oil splatters generated in the pot during cooking from splashing onto the heating device 46, to facilitate cleaning and to avoid the generation of burnt odor. The outer cover 30 is provided with a wind guide channel that passes through a portion of the sidewall 33 of the outer cover 30 corresponding to the position of the inner pot handle 24, to guide the cool air drawn in by the upper fan 42 towards the inner pot handle 24. In practice, the cool air drawn in by the upper fan 42 flows in the first space defined between the outer cover 30 and the inner cover 32, and flows out from the various openings in the sidewall 33 of the outer cover 30, and the wind guide channel is part of the elements that define the flow path in the above. Specifically, the wind guide channel particularly includes the air outlet 62 arranged on the sidewall 33 of the outer cover 30, particularly above the handle 24, so that the cool air flows out from the first space directly towards the handle 24 to achieve cooling of the handle 24. As shown in FIG. 1, the air outlet 62 can be arranged to include a plurality of vertically arranged holes arranged circumferentially. In addition, as shown in FIGS. 1 and 4, the sidewall 33 of the outer cover 30 can be further provided with additional outlets 35, which are advantageous for the cool air to flow out of the outer cover more quickly, to speed up the air circulation and to improve the cooling efficiency. In the present embodiment, as shown in FIG. 4, the wind guide channel further includes a wind guide rib 64 arranged inside the outer cover 30 and a wind guide cover 66 arranged outside the sidewall 33 of the outer cover 30. In other embodiments not shown, the wind guide rib and the wind guide cover are optional features.It is appreciated that the upper fan 42 is driven to rotate around the shaft by the driving device 40, so that the cold air sucked into the first space is also driven to move with a circumferential component, such as in the circumferential direction shown by the arrow R in FIG. 4. Preferably, referring to the left air guide fin 64, the air guide fin 64 is arranged downstream of the air outlet 62 along the airflow direction R, so that the cold air tends to gather at the air outlet 62 due to being blocked by the air guide fin 64, thereby causing more cold air to flow out of the air outlet 62 and improving the cooling efficiency of the handle 24. In addition, as shown in FIG. 4, due to the limitation of other designs, the right air guide fin 64 is not arranged downstream of the entire air outlet 62, but is arranged in the middle of the air outlet 62, which is also an acceptable technical solution. The air guide cover 66 extends outward from the side wall 33 of the outer cover 30 and has a generally inverted U-shaped cross section, which is used to guide the cold air after flowing out of the air outlet 62 to the inner pot handle 24 and prevent the cold air from spreading to useless areas. As shown in FIG. 3, the handle 24 of the inner pot 22 includes a through hole 240, so that the cold air blown out of the air guide channel can pass through the through hole 240 to reach the lower surface 242 of the handle 24. Thus, the upper and lower surfaces of the handle 24 can be cooled at the same time, and the inner pot 22 is also convenient to hold. As shown in FIG. 2, the handle 24 can be a thin shell structure, which is conducive to heat dissipation.
