Abstract
Description
Technical Field
[0001] The utility model relates to the field of kitchen appliances, in particular to a cooking appliance with a heating component arranged in a top cover. Background Art
[0002] In the prior art, various cooking utensils with a heating assembly in the top cover are known, especially air fryers and multifunctional pots with air fryer functions or baking functions. Generally, the heating assembly includes a heating device and a fan, the heating device is used to heat the air, and the fan is used to blow the heated air to the food in the pot to achieve the purpose of cooking.
[0003] Ingredients are usually placed in a removable basket or inner pot inside the pot. Some inner pots have a handle for holding to move the inner pot. When the cooking appliance is in operation, 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 its surface heats up quickly, which may cause safety risks. Utility Model Content
[0004] The utility model aims to provide a cooking utensil to solve the problem of excessively high handle temperature.
[0005] To this end, the utility model proposes a cooking utensil, comprising a pot assembly and a cover assembly covering the pot assembly, wherein the pot assembly comprises an outer shell and an inner pot placed in the outer shell, and the cover assembly comprises an outer cover, an inner cover and an air heating assembly, characterized in that:
[0006] - the inner pot is provided with a handle for resting on the upper edge of the outer shell;
[0007] - the air heating assembly comprises a driving device and an upper fan located in a first space defined between the outer cover and the inner cover, and further comprises a lower fan and a heating device located in a second space defined between the inner cover and the inner pot;
[0008] -The outer cover is provided with an air guiding channel, which passes through a portion of the side wall of the outer cover corresponding to the handle of the inner pot, so as to guide the cold air sucked by the upper fan to the handle of the inner pot.
[0009] According to the utility model, the inner pot is provided with a handle, which can be convenient for holding and moving the inner pot. The handle is designed to be placed on the outer shell, so that there is no need to occupy the space between the outer shell and the inner pot, thereby increasing the volume of the inner pot and improving the cooking efficiency. However, when the cooking utensil is working, the inner pot handle is sandwiched between the pot body outer shell and the cover assembly, so the heat absorbed by the handle from the inner pot cannot be quickly dissipated, resulting in the handle heating up too quickly, exceeding the requirements of safety regulations. For this reason, the cover assembly of the utility model is provided with an upper fan and an air guide channel, which are used to blow cold air to the handle to cool it down. The upper fan is used to suck the room temperature air outside the cooking utensil to cool the components located in the first space to avoid the risk of overheating, and under the action of the upper fan, it flows out from the air guide channel of the outer cover and is guided to the handle of the inner pot. In addition, the upper fan and the lower fan can be set to be driven by the driving device, and advantageously the two work at the same time, so that the room temperature air sucked by the upper fan can continuously reach the handle of the inner pot during the operation of the cooking utensil to cool it and prevent it from heating up too quickly and the temperature is too high. Hereinafter, "room temperature air" and "cold air" are used without distinction.
[0010] Preferably, the air guide channel includes an air outlet arranged in the side wall of the outer cover, and an air guide rib arranged inside the outer cover and / or an air guide cover arranged 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 a part of its flow path. The air outlet can be set only on the part of the side wall of the outer cover corresponding to the position of the inner pot handle, so that the cold air can flow out from the air outlet. More preferably, air guide ribs can be set inside the outer cover to guide the cold air to the air outlet or make the cold air flow to the air outlet more concentratedly. Optionally or alternatively, an air guide cover can also be provided on the outside of the side wall of the outer cover to guide the cold air flowing out of the air outlet to the inner pot handle, or to prevent it from diffusing to useless areas. It can be understood that these features can improve the cooling efficiency of the handle.
[0011] Preferably, the wind guide ribs are arranged downstream of the air outlet in the direction of the airflow generated by the upper fan to block the airflow generated by the upper fan. It can be understood that the upper fan is driven by the driving device to rotate around the axis, thereby driving the cold air sucked into the first space to also move circumferentially. Providing wind guide ribs downstream of the air outlet along the airflow direction can block part of the airflow from continuing to move circumferentially, thereby allowing more cold air to flow to the air outlet, which can improve the cooling efficiency of the handle.
[0012] Preferably, a cold air inlet is provided above the outer cover, and an additional outlet is provided on the side wall of the outer cover. Specifically, for example, the outer cover includes an opening above, and an air inlet cover and an air inlet cover are installed, and a cold air inlet is formed between the two, for example, in the form of multiple slits. Under the action of the rotation of the upper fan, room temperature air enters the first space from the slits and forms a cyclone, thereby cooling the components located in the cover assembly. Afterwards, the cold air flows out from the air outlet provided in the side wall of the outer cover, and also cools the inner pot handle. Providing an additional outlet is conducive to the cold air flowing out of the outer cover more quickly, speeding up the air circulation speed, and improving the cooling efficiency.
[0013] Preferably, the handle includes a through hole, so that the cold air blown out from the air guide channel can pass through the through hole and reach the lower surface of the handle, thereby cooling the upper and lower surfaces of the handle at the same time, and making it convenient to hold the inner pot.
[0014] Preferably, the handle is a thin shell structure, which is conducive to heat dissipation.
[0015] Preferably, the inner cover is a heat-insulating 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 improperly heating the components arranged therein, thereby causing safety hazards.

[0022] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the utility model. Instead, they are only examples of devices, systems, equipment and methods consistent with some aspects of the utility model.
[0023] Figure 1 A cooking utensil 1 according to a preferred embodiment of the present invention is shown, which is a multifunctional pot in this example, in particular a multifunctional pot with a baking function or an air fryer function. Specifically, the cooking utensil 1 comprises a pot assembly 2 and a cover assembly 3 that can cover the pot assembly 2. Figure 1 As shown, the cover assembly 3 is hingedly arranged at one end of the pot assembly 2.
[0024] The pot assembly 2 includes an outer shell 20 and an inner pot 22 movably disposed in the outer shell. The pot assembly 2 may also include a plurality of inner pots that are replaceable with each other. Figure 3 As shown, a movable grill 220 may be provided in the inner pot 22. Handles 24 are provided at two radially opposite locations on the outer wall of the inner pot 22. Figure 1 As shown, a handle support portion 26 is correspondingly provided on the outer shell 20. With the handle support portion 26 supporting the handle 24, the inner pot 22 is placed on the upper edge of the outer shell 20. In a preferred embodiment, the handle support portion 26 includes a longitudinal notch provided in the upper edge of the outer shell 20, so that when the handle 24 of the inner pot 22 is placed thereon, the upper edge of the inner pot 22 is only slightly higher than the upper edge of the outer shell 20. In addition, the handle support portion 26 may also include a raised groove provided on the outer wall of the outer shell 20, and the handle 24 is accommodated in the raised groove, so that the cooking utensil 1 is more beautiful when the lid assembly 2 is closed.
[0025] The cover assembly 3 includes an outer cover 30, an inner cover 32 and an air heating assembly 4. Figure 3 As shown, the outer cover 30 includes an opening 310 at the top. Figure 2 As shown, an air intake cover seat 311 and an air intake cover 312 are installed 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 intake cover 312. The space defined between the outer cover 30 and the inner cover 32 is called a first space, and the driving device 40 and the upper fan 42 of the air heating assembly 4 are arranged in the first space. The space defined between the inner cover 32 and the inner pot 22 is called a second space, and the lower fan 44 and the heating device 46 of the air heating assembly 4 are arranged in the second space.
[0026] The driving device 40 is, for example, an electric motor and is fixed in the inner cover 30 in a known manner, for example, by providing a support seat. The driving device 40 includes 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 cover 32 to directly or indirectly drive the lower fan 44 to rotate. The upper fan 42 rotates, causing room temperature air to be sucked into the first space from the air inlet 31 to cool the components therein, and then flows out from the air outlet 62 to cool the handle. The lower fan 44 rotates, causing the air used for heating in the pot to enter the second space from another air inlet (not shown in the figure) to participate in cooking. The air duct paths passed by the air for cooling and heating are independent of each other and will not interfere with each other.
[0027] Preferably, the inner cover 32 is a heat-insulating cover that separates the first space from the cooking space, especially the heating device 46, thereby preventing the heat generated by the heating device 46 from entering the first space and improperly heating the components disposed therein, thereby causing safety hazards.
[0028] Preferably, if Figure 1 and Figure 2 As shown, the cover assembly 4 may further include a protective cover 48 disposed below the heating device 46 to prevent oil stains generated in the pot during cooking from splashing onto the heating device 46, thereby facilitating cleaning and avoiding the generation of burnt odors.
[0029] An air guiding channel is provided in the outer cover 30, and the air guiding channel passes through the portion of the side wall 33 of the outer cover 30 corresponding to the inner pot handle 24, so as to guide the cold air sucked in by the upper fan 42 to the inner pot handle 24. In fact, the cold air sucked 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 on the side wall 33 of the outer cover 30. The air guiding channel is a part of the components that define the above-mentioned flow path. Specifically, the air guiding channel especially includes an air outlet 62, which is arranged on the side wall 33 of the outer cover 30, and especially above the handle 24, so that the cold air flows out from the first space and blows directly to the handle 24, so as to cool the handle 24. Figure 1 As shown, the air outlet 62 may be configured to include a plurality of vertical holes arranged in a circumferential direction. Figure 1 and Figure 4 As shown, an additional outlet 35 may be provided on the side wall 33 of the outer cover 30, which helps the cold air to flow out of the outer cover more quickly, speeds up the air circulation, and improves the cooling efficiency.
[0030] In this embodiment, if Figure 4As shown, the air guide channel also includes an air guide rib 64 disposed inside the outer cover 30 and an air guide cover 66 disposed outside the side wall 33 of the outer cover 30. In other embodiments not shown, the air guide rib and the air guide cover are optional features. It can be understood that the upper fan 42 is driven by the driving device 40 to rotate around the axis, thereby driving the cold air sucked into the first space to also move with a circumferential component, such as along the Figure 4 Preferably, referring to the left wind guide rib 64, a wind guide rib 64 is provided downstream of the air outlet 62 along the air flow direction R, so that the cold air tends to gather at the air outlet 62 due to being blocked by the wind guide rib 64, thereby allowing more cold air to flow out of the air outlet 62, thereby improving the cooling efficiency of the handle 24. In addition, as Figure 4 As shown, due to the limitations of other designs, the right wind guide rib 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 wind guide cover 66 extends outward from the side wall 33 of the outer cover 30, and the cross section is generally inverted U shape. It is used to guide the cold air flowing out of the air outlet 62 to the inner pot handle 24 to prevent the cold air from spreading to useless areas.
[0031] like Figure 3 As shown, the handle 24 of the inner pot 22 includes a through hole 240, so that the cold air blown out from the air guide channel can pass through the through hole 240 and reach the lower surface 242 of the handle 24. In this way, the upper and lower surfaces of the handle 24 can be cooled at the same time, and it is also convenient to hold the inner pot 22. Figure 2 As shown, the handle 24 may be a thin shell structure to facilitate heat dissipation.
