Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a cooking utensil. Background Technology

[0002] Existing cooking appliances often result in rice sticking to the pot during cooking, making it difficult to clean the inner pot after meals and negatively impacting the user experience.

[0003] To solve this technical problem, the applicant has previously applied for a water-wetting film coating technology. By installing a cooling fan on the pot body, the operation of the cooling fan creates an airflow to cool the inner pot. This causes the high-temperature steam inside the inner pot to quickly condense into condensate when it comes into contact with the inner pot, forming a water film between the food and the inner wall of the inner pot. This prevents the food from sticking to the inner wall of the inner pot and achieves a non-stick effect.

[0004] However, heating elements are typically located at the bottom of the inner pot, concentrating heat on the bottom, while the fan is positioned on the side, blowing cool air towards the sides. This arrangement results in two problems: first, the heat source is singular, concentrating heat on the bottom of the inner pot while the sides receive less heat, leading to uneven heating and affecting the texture of the food. Second, because the sides of the inner pot are already cool, the temperature difference between the airflow and the sides is small, making it difficult to generate sufficient condensation to form a moist film. This results in poor film thickness and uniformity, hindering the creation of a good non-stick effect.

[0005] Furthermore, the installation of the fan occupies a large space on the side of the pot, making it difficult to install heating elements on the side of the pot. On the one hand, this increases the complexity and difficulty of assembly, and on the other hand, the cramped space on the side of the pot makes it easy for the fan and heating elements to interfere with each other, thereby affecting the side heating effect and the air cooling effect. Utility Model Content

[0006] This utility model provides a cooking appliance to solve the problems of small temperature difference between the inner pot side and the airflow, making it difficult to form a uniform water film, as well as the high complexity and difficulty in installing the fan and heating element on the side of the pot.

[0007] The technical solution adopted in this utility model is as follows:

[0008] A cooking appliance includes a pot body with a accommodating cavity and an inner pot placed inside the accommodating cavity. A first heating device is disposed below the accommodating cavity, and a second heating device is disposed on the outer periphery of the accommodating cavity. A fan assembly is disposed on the side of the pot body for supplying cold air to the side of the inner pot. The fan assembly is fixedly connected to the second heating device so that the fan assembly and the second heating device form an installation unit and are fixed to the pot body.

[0009] The cooking appliance of this utility model also has the following additional technical features:

[0010] The first heating device includes a fixed bracket and a first heating element disposed on the fixed bracket. A fixing element is disposed at the pot opening of the pot body, and the fixing element and the fixed bracket clamp and fix the second heating device.

[0011] The fixed bracket includes a body and a surrounding rib extending upward from the edge of the body. There is a stepped portion between the body and the surrounding rib. The stepped portion abuts against the lower end of the second heating device. The surrounding rib surrounds the outer periphery of the second heating device, and the surrounding rib is provided with a clearance notch corresponding to the fan assembly.

[0012] The second heating device has an air inlet, and fixed positions are provided on both sides of the air inlet. The fan assembly includes a blower and a mounting part located outside the blower. The mounting part is fixedly connected to the fixed position so that the air inlet and the blower are connected.

[0013] The fan assembly includes a fan, a shock-absorbing pad, and an air guide. The air guide has an internal air channel that communicates with the fan. The shock-absorbing pad has a first mounting side and a second mounting side that are arranged opposite to each other. The first mounting side is fixedly connected to the fan, and the second mounting side is fixedly connected to the air guide.

[0014] A filter element is provided between the air guide and the second heating device. The air guide and the second heating device are fixedly connected so that the air guide and the second heating device clamp and fix the filter element.

[0015] The first mounting side is provided with a fixing post protruding towards the fan. The fan is provided with a through hole corresponding to the fixing post. The fixing post is provided with a stop rib, which passes through the through hole to cooperate with the fan stop.

[0016] The second heating device includes a heating ring and a second heating element disposed on the heating ring, wherein the second heating element is located on the side of the heating ring facing the receiving cavity; or, the second heating element is located on the side of the heating ring away from the receiving cavity.

[0017] The inner liner has a maximum food mark on its side wall, and the projection of the second heating device toward the inner liner covers the maximum food mark.

[0018] The cooking appliance has a cooking stage and a depressurization stage. During the cooking stage, the fan assembly is activated to blow cold air into the inner liner; and / or, during the depressurization stage, the fan assembly is activated to blow cold air into the inner liner.

[0019] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0020] 1. In this invention, the inner pot is placed within a receiving cavity. A first heating device is located below the receiving cavity, and a second heating device is located on the outer periphery of the receiving cavity. The first heating device heats the bottom of the inner pot, and the second heating device heats the sides of the inner pot, thereby ensuring that both the bottom and sides of the inner pot are heated evenly, resulting in better cooking performance. Furthermore, the presence of the second heating device results in a higher temperature on the sides of the inner pot. When the fan assembly blows cool air onto the sides of the inner pot, the temperature difference between the airflow and the sides of the inner pot is greater, which is more conducive to forming a sufficient and uniform moist film, ensuring a non-stick effect. Furthermore, the fan assembly is fixed to the second heating device. This integration allows for a more compact structure, saving space on the side of the pot and improving space utilization. It also ensures more precise positioning of the air inlets on both the fan assembly and the second heating device, allowing the airflow from the fan to pass smoothly through the second heating device and into the receiving cavity. This avoids the inaccurate positioning of the fan assembly and air inlet, which would affect the cooling effect, if the fan assembly and the second heating device were fixed separately. On the other hand, fixing the fan assembly to the second heating device creates a single unit, allowing for complete installation of both components within the pot. This simplifies the assembly process and improves efficiency.

[0021] 2. In a preferred embodiment of this utility model, the first heating device includes a fixed bracket and a first heating element disposed on the fixed bracket. A fixing element is disposed at the pot opening, and the fixing element and the fixed bracket clamp and fix the second heating device. The fixed bracket is located below the second heating device, and the fixing element is located at the pot opening, above the second heating device. The two clamp and fix the second heating device from above and below, ensuring the stability of the second heating device while eliminating the need for complex fixing structures on the second heating device, thus reducing processing difficulty and saving space on the side of the pot body. Furthermore, the second heating device and the fixing element are separate structures, allowing the second heating device to be manufactured as a single component, thereby facilitating the installation and fixing of the second heating device and the fan assembly.

[0022] 3. In a preferred embodiment of this utility model, the fixed support includes a main body and a surrounding rib extending upward from the edge of the main body. A stepped portion is provided between the main body and the surrounding rib. The stepped portion abuts against the lower end of the second heating device. The surrounding rib surrounds the outer periphery of the second heating device, and a clearance notch is provided for the surrounding rib corresponding to the fan assembly. The stepped portion serves as the abutment point for the second heating device, making the contact between them more stable, thereby providing stable and reliable support for the second heating device. The surrounding rib surrounds the outer periphery of the second heating device, which on the one hand positions the second heating device, allowing it to be placed more accurately on the stepped portion; on the other hand, it blocks the heat from the second heating device, confining the heat within the accommodating cavity and directing more heat radiation towards the inner liner, reducing heat loss and improving heat utilization and heating efficiency. Simultaneously, the clearance notch provided for the surrounding rib corresponding to the fan assembly not only positions the fixed support and fan assembly but also makes the structure of the pot side more compact, helping to save space.

[0023] 4. In a preferred embodiment of this utility model, the side wall of the inner pot is provided with a maximum food mark, and the projection of the second heating device toward the inner pot covers the maximum food mark. Because the second heating device covers the maximum food mark, the heating position of the second heating device on the inner pot is located near the upper surface of the food. This allows the food to be heated simultaneously from both the top and bottom, improving the uniformity of heating and ensuring the cooked taste. Furthermore, during the heat preservation process, using the second heating device to heat and preserve the upper surface of the food shortens the heat transfer path, improves heat preservation efficiency, saves overall power consumption of the heating device, and avoids the bottom of the food from burning due to bottom heating.

[0024] 5. In a preferred embodiment of this utility model, the cooking appliance has a cooking stage and a depressurization stage. During the cooking stage, the fan assembly is activated to blow cold air into the inner pot; and / or, during the depressurization stage, the fan assembly is activated to blow cold air into the inner pot. The fan assembly in this utility model has multiple functions. During the cooking stage, when the food is gelatinizing, the fan assembly utilizes the temperature difference between the inside and outside of the pot to form a moist film on the inner wall of the inner pot, thereby preventing direct contact between the food and the inner pot wall, effectively improving the non-stick effect. During the depressurization stage, the fan assembly, for pressure cooking appliances, can achieve rapid pressure release by cooling with the fan, which greatly shortens the depressurization time compared to natural pressure release, thus facilitating quick opening of the lid.

[0043] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0044] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0046] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0047] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0048] like Figure 1 , Figure 2 As shown, a cooking appliance includes a pot body with a accommodating cavity 7 and an inner pot 4 placed inside the accommodating cavity 7. A first heating device 1 is disposed below the accommodating cavity 7, and a second heating device 2 is disposed on the outer periphery of the accommodating cavity 7. A fan assembly 3 is disposed on the side of the pot body. The fan assembly 3 is used to supply cold air to the side of the inner pot 4. The fan assembly 3 is fixedly connected to the second heating device 2 so that the fan assembly 3 and the second heating device 2 form an installation unit and are fixed to the pot body.

[0049] In this invention, the inner pot 4 is placed inside the accommodating cavity 7. A first heating device 1 is provided below the accommodating cavity 7, and a second heating device 2 is provided on the outer periphery of the accommodating cavity 7. The first heating device 1 is used to heat the bottom of the inner pot 4, and the second heating device 2 is used to heat the sides of the inner pot 4, so that the bottom and sides of the inner pot 4 are heated together, making the heating of each area of ​​the inner pot 4 more uniform and the cooking effect of food better.

[0050] In addition, due to the presence of the second heating device 2, the temperature of the side of the inner liner 4 is relatively high. When the fan assembly 3 blows cold air to the side of the inner liner 4, the temperature difference between the airflow and the side of the inner liner 4 is relatively large, which is more conducive to forming a sufficient and uniform wet film and ensuring the non-stick effect.

[0051] The fan assembly 3 is fixed to the second heating device 2. This integration of the fan assembly 3 and the second heating device 2 creates a more compact structure, saving space on the side of the pot and improving space utilization. It also allows for more precise positioning of the air inlet 21 on both the fan assembly 3 and the second heating device 2, ensuring the airflow from the fan assembly 3 passes smoothly through the second heating device 2 and enters the receiving cavity 7. This avoids the situation where the fan assembly 3 and the second heating device 2 are fixed separately, leading to inaccurate positioning of the fan assembly 3 and the air inlet 21 and affecting the cooling effect. Furthermore, fixing the fan assembly 3 to the second heating device 2 forms a single component, constituting an installation unit that can be fixed to the inside of the pot. This allows for simultaneous fixing of the fan assembly 3 and the second heating device 2 in a single operation, greatly simplifying the assembly process and improving assembly efficiency.

[0052] Preferably, such as Figure 8 As shown, the projection of the fan assembly 3 toward the inner liner 4 is located on the height centerline of the inner liner 4, so that when the fan assembly 3 blows cold air into the accommodating cavity 7, the airflow blows toward the middle of the inner liner 4. After contacting the inner liner 4, part of it flows down along the side wall of the inner liner 4 to the bottom of the inner liner 4, part of it flows up to the top of the inner liner 4, and part of it flows around the inner liner 4 in a circumferential direction. Multiple airflows form a complete surround on the inner liner 4, which helps to improve the uniformity of cooling of the inner liner 4 and make the distribution of the water film on the inner surface of the inner liner 4 more uniform.

[0053] It should be noted that this utility model does not limit the number of fan components 3, such as... Figure 1 As shown, there can be one fan assembly 3, arranged on one side of the inner liner 4. Of course, there can also be two fan assemblies 3, arranged along the opposite side of the inner liner 4, or there can be more fan assemblies, arranged at intervals along the circumference of the inner liner 4.

[0054] As a preferred embodiment of this utility model, such as Figure 1 , Figure 3 , Figure 4 , Figure 8 As shown, the first heating device 1 includes a fixed bracket 11 and a first heating element disposed on the fixed bracket 11. A fixing element 5 is disposed at the pot opening of the pot body. The fixing element 5 and the fixed bracket 11 clamp and fix the second heating device 2.

[0055] The fixing bracket 11 is located below the second heating device 2, and the fixing member 5 is located at the pot opening, above the second heating device 2. The two clamp the second heating device 2 from above and below, ensuring the stability of the second heating device 2 while eliminating the need to process complex fixing structures on the second heating device 2, thus reducing processing difficulty and saving space on the side of the pot. In addition, the second heating device 2 and the fixing member 5 are separate structures, allowing the second heating device 2 to be manufactured as a separate component, which facilitates the installation and fixing of the second heating device 2 and the fan assembly 3.

[0056] It should be noted that this utility model does not limit the heating method of the first heating element and the second heating device 2. In one embodiment, the first heating element is an electromagnetic coil wound on the fixed bracket 11 to heat the bottom of the inner liner 4 by electromagnetic heating, achieving non-contact heating. At the same time, there is a gap between the bottom of the inner liner 4 and the first heating device 1 to facilitate the passage of airflow, allowing the airflow to contact the bottom of the inner liner 4 and improve the cooling effect. In another embodiment, the first heating element is a heating plate that contacts the bottom of the inner liner 4 to heat the bottom of the inner liner 4 by contact. Of course, the second heating device 2 can also be electromagnetic heating or a heating element. However, regardless of the structure of the second heating device 2, there is a gap between it and the side wall of the inner liner 4. Therefore, when the second heating device 2 is a heating element, the side of the inner liner 4 is heated by radiation rather than by contact heating.

[0057] Furthermore, such as Figure 3 , Figure 4 , Figure 7 , Figure 9As shown, the fixed bracket 11 includes a body 111 and a surrounding rib 112 extending upward from the edge of the body 111. There is a step portion 115 between the body 111 and the surrounding rib 112. The step portion 115 abuts against the lower end of the second heating device 2. The surrounding rib 112 surrounds the outer periphery of the second heating device 2, and the surrounding rib 112 is provided with an avoidance notch 113 corresponding to the fan assembly 3.

[0058] The step portion 115 serves as the abutment point for the second heating device 2, making the contact between them more stable and thus providing stable and reliable support for the second heating device 2. The surrounding rib 112 encircles the outer periphery of the second heating device 2, serving two purposes: firstly, it positions the second heating device 2, allowing it to be placed more accurately on the step portion 115; secondly, it blocks the heat from the second heating device 2, confining it within the receiving cavity 7 and directing more heat towards the inner liner 4, reducing heat loss and improving heat utilization and heating efficiency. Simultaneously, the surrounding rib 112 has a clearance notch 113 corresponding to the fan assembly 3, which not only positions the fixed bracket 11 and the fan assembly 3 but also makes the side structure of the pot body more compact, helping to save space.

[0059] Specifically, such as Figure 9 As shown, the stepped portion 115 has a supporting surface, and the lower end of the second heating device 2 is in contact with the supporting surface. Figure 3 , Figure 4 As shown, the edge of the clearance notch 113 is provided with a positioning flange 114 extending outward toward the receiving cavity 7 to improve the positioning accuracy of the fan assembly 3 and the fixed bracket 11.

[0060] Furthermore, such as Figure 2 , Figure 5 , Figure 6 , Figure 9 As shown, the second heating device 2 has a ring structure, and its top and / or bottom ends are provided with reinforcing rolled edges 25 to improve strength and stability of clamping the second heating device 2.

[0061] Specifically, such as Figure 6 As shown, the reinforcing rolled edge 25 at the top of the second heating device 2 is rolled into an arc or circle so as to contact the fixing member 5 through the arc surface. The reinforcing rolled edge 25 at the bottom has a contact plane for contacting the supporting plane of the step portion 115. Of course, the structures of the reinforcing rolled edges 25 at the top and bottom ends can be interchanged, or the same rolled edge structure can be used, or other rolled edge structures can be used, which is not limited here.

[0062] Both the fixing component 5 and the fixing bracket 11 are provided with connecting columns, and the two are fastened together by screws and other fasteners to form a clamping force on the second heating device 2.

[0063] Preferably, such as Figure 1 , Figure 3 As shown, a handle 41 is provided on the outer periphery of the inner pot 4, and the fan assembly 3 is located below the handle 41. During cooking, the highest point of the food inside the inner pot 4 is generally below the handle 41. Placing the fan assembly 3 below the handle 41 allows the cooling airflow to directly blow on the surface of the inner pot 4 corresponding to the food, resulting in a greater temperature difference and better formation of a moist film, thus enhancing the lubrication and non-stick effect. At the same time, the handle 41 being above the fan assembly 3 does not obstruct the airflow, allowing for better circulation of cold air within the cavity 7, which helps to increase the temperature difference and enhance the non-stick effect.

[0064] Specifically, such as Figure 1 As shown, the fixing member 5 is provided with a positioning notch corresponding to the grip handle 41, so that after the inner liner 4 is inserted, it can avoid the grip handle 41 and can also play a positioning role in the placement of the inner liner 4.

[0065] In a preferred embodiment, such as Figure 2 , Figure 5 As shown, the second heating device 2 has an air inlet 21, and fixed positions 22 are provided on both sides of the air inlet 21. The fan assembly 3 includes a blower 34 and a mounting part 35 located outside the blower 34. The mounting part 35 is fixedly connected to the fixed position 22 so that the air inlet 21 and the blower 34 are connected and communicated.

[0066] The blower section 34 is where the fan blades are located. It is aligned with the air inlet 21, so that all the airflow blown out by the fan 31 can enter the accommodating cavity 7 through the air inlet 21. The mounting section 35 is provided with a mounting structure for fixed connection with the second heating device 2. It is located outside the blower section 34, so that the fixing structure will not block the airflow blown out by the blower section 34, thus ensuring the efficiency of airflow.

[0067] Specifically, such as Figure 2 As shown, the fixing position 22 includes mounting holes on both sides of the air inlet 21, and the mounting part 35 is a mounting rib protruding on both sides of the blower part 34. The mounting rib also has mounting holes, and the two are fastened together by screws or other fasteners.

[0068] Of course, more mounting holes can be provided, spaced apart on the outer periphery of the air inlet 21, to improve the stability of the fixation. Alternatively, the fixing position 22 and the mounting part 35 can be provided with other fixing structures to fix and connect them in other ways, such as snap-fit ​​connections, etc., which are not limited here.

[0069] In a preferred embodiment of this utility model, such as Figure 2 , Figure 5As shown, the fan assembly 3 includes a fan 31, a shock-absorbing pad 33, and an air guide 32. The air guide 32 has an air guide channel 321 that communicates with the fan 31. The shock-absorbing pad 33 has a first mounting side 331 and a second mounting side that are arranged opposite to each other. The first mounting side 331 is fixedly connected to the fan 31, and the second mounting side is fixedly connected to the air guide 32.

[0070] The air guide 32 is fixed to the side of the pot body, leaving space for other necessary structures of the pot body, making the structural layout of the pot body more compact and saving space. In addition, the air guide channel 321 can not only guide the airflow blown out by the fan 31 into the cavity 7, but also appropriately lengthen the distance between the fan 31 and the second heating device 2, thereby reducing the heat transferred from the second heating device 2 to the fan 31 and preventing the fan 31 from being damaged at high temperatures.

[0071] The shock-absorbing pad 33 not only reduces the vibration transmitted from the fan 31 to the air guide 32, but also serves as a mounting bracket. By fixing the air guide 32 and the fan 31 to both sides of the shock-absorbing pad 33, the two clamp the shock-absorbing pad 33 from both sides, reducing the installation difficulty of the fan 31.

[0072] Furthermore, such as Figure 2 As shown, a filter element 6 is provided between the air guide 32 and the second heating device 2. The air guide 32 and the second heating device 2 are fixedly connected so that the air guide 32 and the second heating device 2 clamp and fix the filter element 6.

[0073] Specifically, such as Figure 2 As shown, the filter element 6 is a filter screen. A fixing part is provided on the outer periphery of the filter screen. When fixing the filter screen, the filter screen can be fixed by using the air guide part and the second heating device 2 to clamp the fixing part. Alternatively, a through hole can be opened in the fixing part, and the air guide part 32 and the second heating device 2 can be fastened together by screws or other fasteners passing through the through hole, so that the air guide part 32 and the second heating device 2 clamp the filter element 6 under the action of pre-tightening force.

[0074] Specifically, such as Figure 2 As shown, the first mounting side 331 is provided with a fixing post 332 protruding towards the fan 31. The fan 31 is provided with a through hole 311 corresponding to the fixing post 332. The fixing post 332 is provided with a stop rib 333, which passes through the through hole 311 to cooperate with the fan 31.

[0075] Preferably, both the shock-absorbing pad 33 and the fixing column 332 are structures made of elastic material. For example... Figure 2As shown, a mounting groove for accommodating the fan 31 is formed between the stop rib 333 and the first mounting side 331. The fan 31 is stopped on both sides by the first mounting side 331 and the stop rib 333, respectively, to restrict the position of the fan 31. Furthermore, the fixing post 332 is an elastic structure that can be inserted into the through hole 311 by interference fit to smoothly pass through the fan 31. When the stop rib 333 passes through the fan 31, it returns to its original position under its own elastic force, forming a stop with the end face of the fan 31.

[0076] Preferably, such as Figure 2 As shown, a fixing column 332 is also provided on the second installation side, and the air guide 32 and the shock absorber 33 are fixedly connected in the same way.

[0077] In a preferred embodiment, such as Figure 5 As shown, the second heating device 2 includes a heating ring 23 and a second heating element 24 disposed on the heating ring 23. It should be noted that the present invention does not limit the location of the second heating element 24. In one embodiment, the second heating element 24 is located on the side of the heating ring 23 facing the accommodating cavity 7. Since the second heating element 24 is located inside the accommodating cavity 7, during cooking, the heat from the second heating element 24 is radiated to the side of the inner pot 4 through the air inside the accommodating cavity 7, radiating heat to the side of the inner pot 4, which shortens the heat transfer path and improves heat transfer efficiency.

[0078] In another embodiment, such as Figure 5 , Figure 6 As shown, the second heating element 24 is located on the side of the heating ring 23 away from the receiving cavity 7. Because the second heating element 24 is located outside the receiving cavity 7, during cooking, the heat from the second heating element 24 is first transferred to the heating ring 23 and then radiated to the side of the inner pot 4. This placement of the second heating element 24 outside the receiving cavity 7 prevents it from being contaminated by liquids, food residue, or other impurities.

[0079] Specifically, in one embodiment, such as Figure 5 As shown, the second heating element 24 is a heating tube. Of course, the second heating element 24 can also be an electromagnetic coil, which is not limited here.

[0080] In a preferred embodiment of this utility model, the inner liner 4 has a maximum food mark on its side wall, and the projection of the second heating device 2 toward the inner liner 4 covers the maximum food mark.

[0081] The second heating device 2 covers the largest food mark, thus placing the heating position of the second heating device 2 on the inner pot 4 near the upper surface of the food. On the one hand, this allows the food to be heated from both the top and bottom sides simultaneously, improving the uniformity of heating and ensuring the taste of the food. On the other hand, during the heat preservation process, the second heating device 2 heats and keeps the upper surface of the food warm. Compared with bottom heating, this shortens the heat transfer path, improves heat preservation efficiency, saves the overall power consumption of the heating device, and avoids the bottom of the food from burning due to bottom heating.

[0082] It should be noted that this utility model does not limit the function of the fan assembly 3 or the start-up time. In one embodiment, the cooking appliance has a cooking stage, during which the fan assembly 3 starts to blow cold air into the inner pot 4.

[0083] The fan assembly 3 in this invention has multiple functions. During the cooking stage, the fan assembly 3 starts working. During the food gelatinization stage, the temperature difference between the inside and outside of the pot is used to form a moist film on the inner wall of the inner pot 4, thereby preventing the food from directly contacting the inner pot 4 wall and effectively improving the non-stick effect.

[0084] In another embodiment, the cooking appliance is a pressure cooking appliance having a cooking stage and a depressurization stage, during which the fan assembly 3 is activated to blow cold air into the inner liner 4.

[0085] When the fan assembly 3 starts working during the depressurization phase, the pressure cooker can achieve rapid depressurization by cooling down the pressure using the fan 31. Compared with the natural depressurization method, this can greatly shorten the depressurization time, thus helping to open the lid quickly.

[0086] In a preferred embodiment, the cooking appliance is a pressure cooking appliance having a cooking stage and a depressurization stage, during which the fan assembly 3 is activated to blow cold air into the inner liner 4.

[0087] In this embodiment, the fan assembly 3 is activated during both the cooking and depressurization stages, enabling the cooking appliance to integrate air-cooling anti-stick and air-cooling depressurization functions, giving the fan assembly 3 more uses and improving the user experience.

[0088] For any parts not mentioned in this utility model, existing technologies can be used or referenced.

[0089] The various embodiments in this specification are described in a progressive manner. The same or similar parts between the various embodiments can be referred to each other. Each embodiment focuses on describing the differences from other embodiments.

[0090] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
