Description

Technical Field

[0001] The utility model relates to the technical field of household electrical appliances, in particular to a pot cover assembly of a cooking utensil and the cooking utensil. Background Art

[0002] After cooking, existing pressure cookers maintain high pressure inside, requiring decompression before the lid can be opened. Traditional pressure cookers typically feature a venting mechanism on the lid. After cooking, pressing the vent button causes a push rod to lift a weight, connecting the pot to the outside world and releasing the pressure. This releases the float on the lid, allowing the lid to be opened.

[0003] However, traditional pressure cooking appliances require manual pressing of the exhaust button to exhaust, which takes a long time and causes sore fingers, which is a bad experience. When there is a lot of food in the pot, continuously pressing the exhaust button manually will cause the food and soup to overflow, which is difficult to clean. For example, when a large amount of porridge is cooked in the pot, the exhaust cannot be released, and it takes a long time to rely on natural pressure reduction.

[0004] In order to solve the problems caused by manual exhaust, related technologies have proposed a pressure cooking appliance that uses air cooling and pressure reduction. By arranging a fan on the pot body or lid of the pressure cooking appliance, cooling air is blown to the inner pot or the lid through the fan, quickly removing the heat of the inner pot or the lid and reducing the pressure in the pot, thereby achieving the purpose of no exhaust and pressure reduction and quick lid opening.

[0005] However, the existing air-cooling pressure reduction solution has an unreasonable air-cooling structure, which results in the float on the pot lid not responding quickly. There is a problem that even if the pressure in the pot has dropped to a pressure where the lid can be opened, it is still necessary to wait for the float on the pot lid to drop before opening the lid, which affects the user experience.

[0012] In some embodiments, an installation space is formed between the outer cover and the inner cover and is located in a peripheral area of the inner cover, and the first fan is disposed in the installation space;

[0013] And / or, the inner cover has a front end and a rear end opposite to each other in the front-to-rear direction, the first fan is arranged in the rear end area of the inner cover, and the air outlet of the first fan faces the front end of the inner cover.

[0014] In some embodiments, the pot cover assembly of the cooking utensil further comprises a lining cover, wherein the lining cover is disposed between the outer cover and the inner cover;

[0016] In some embodiments, wind guide ribs are provided on one side surface of the lining cover facing the inner cover, and the wind guide ribs are located on the air outlet side of the first fan. The wind guide ribs are formed into an eight-shaped structure that gradually extends away from the first fan and away from both sides, so as to divide and guide the wind blown out by the first fan so that it flows around the inner cover.

[0017] In some embodiments, the pot cover assembly of the cooking appliance further comprises a lining cover, wherein the lining cover is at least partially located between the peripheral edge of the outer cover and the peripheral edge of the inner cover;

[0018] A first air outlet gap is formed between the peripheral edge of the inner cover and the peripheral edge of the lining cover, and the first air outlet gap is communicated with the air duct cavity.

[0019] A second aspect of the present invention provides a cooking utensil, comprising a pot body assembly and a pot cover assembly as described in any of the above embodiments, wherein the pot cover assembly is openably and closably mounted on the pot body assembly.

[0020] In some embodiments, a covering gap is formed between the pot cover assembly and the pot body assembly, and the covering gap is formed as a peripheral air outlet communicating with the air duct cavity;

[0021] Moreover, a height of a covering gap formed between a rear end portion of the pot cover assembly and the pot body assembly is greater than a height of a covering gap formed between a front end portion of the pot cover assembly and the pot body assembly.

[0023] A second air inlet is provided on the side wall of the pot body, a second fan corresponding to the second air inlet is provided on the pot body, a second air outlet gap is formed between the top periphery of the pot body and the top periphery of the inner pot, and / or a bottom air outlet is provided at the bottom of the pot body.

[0024] The technical solution provided by the embodiment of the utility model has at least the following advantages compared with the prior art:

[0025] 1. A first fan is arranged between the outer cover and the inner cover of the pot lid assembly, and an air duct cavity is formed between the outer cover and the inner cover, so that cooling air is blown into the air duct cavity by the first fan, quickly taking away the heat of the inner cover, reducing the temperature of the inner cover, thereby reducing the temperature of the steam in the pot, and reducing the air pressure in the pot, achieving the purpose of exhaust-free pressure reduction; a float assembly is provided on the inner cover, and the float assembly is partially located in the air duct cavity. In this way, when the first fan blows cooling air into the air duct cavity, the cooling air can be blown to the float assembly, thereby cooling the inner cover and the steam in the pot, and at the same time, the temperature of the float assembly and the steam around the float assembly can be reduced more quickly, so that the air pressure around the float assembly is reduced, and the float assembly falls in time, so that the lid can be opened quickly after the float assembly falls, thereby solving the problem that the float on the pot lid cannot react quickly, resulting in the pressure in the pot being reduced to the pressure where the lid can be opened but the lid cannot be opened, thereby improving the user experience.

[0026] 2. The float assembly is partially located in the area formed by the air outlet of the first fan extending along the central axis of the first fan to ensure that the cooling air blown by the first fan can be better blown to the float assembly, thereby more effectively cooling the float assembly.

[0027] 3. By vertically or obliquely arranging the first fan between the outer cover and the inner cover, and the central axis of the first fan is perpendicular to the central axis of the inner cover or the angle between the two is greater than 45 degrees, the cooling air blown out by the first fan can flow horizontally or approximately horizontally in the air duct cavity, so that the cooling air can flow along the top surface of the inner cover, reducing wind resistance, increasing the contact area between the cooling air and the inner cover, and improving heat dissipation efficiency.

[0028] 4. An installation space located in the peripheral area of the inner cover is formed between the outer cover and the inner cover. By arranging the first fan in the installation space, the installation space in the peripheral area of the inner cover can be fully utilized, and the first fan can be installed on the pot cover assembly without increasing or excessively increasing the overall height of the pot cover assembly.

[0029] 5. The inner cover has a front end and a rear end that are opposite to each other in the front-to-back direction. By arranging the first fan in the rear end area of the inner cover with the air outlet of the first fan facing the front end of the inner cover, the space in the rear end area of the inner cover can be fully utilized to install the first fan, and the cooling air blown out by the first fan can be blown from back to front to cool the entire surface of the inner cover, which is beneficial to improving the heat dissipation efficiency.

[0030] 6. By arranging a lining cover between the outer cover and the inner cover, and the lining cover surrounding and covering the inner cover, a relatively closed air duct cavity is formed between the lining cover and the inner cover, and the cooling air blown out by the first fan is confined to the interlayer formed between the lining cover and the inner cover, so as to better utilize the cooling air to cool the inner cover and the steam in the pot; in addition, by arranging the lining cover, the outer cover can also be isolated to avoid the temperature of the outer cover being too high during cooking.

[0031] 7. By providing an eight-shaped air guide rib on the side surface of the lining cover facing the inner cover, the air blown out by the first fan is divided and guided by the air guide rib so that it flows around the inner cover, thereby increasing the contact area between the cooling air and the inner cover and achieving more effective cooling of the inner cover.

[0032] 8. A first air outlet gap connected to the air duct cavity is formed between the peripheral edge of the inner cover and the peripheral edge of the lining cover, so that the cooling air blown out by the first fan can flow out from the first air outlet gap between the lining cover and the inner cover after cooling the inner cover, thereby ensuring the rapid circulation of cooling air in the air duct cavity and being beneficial to improving the heat dissipation efficiency; in addition, the air is discharged from the first air outlet gap formed between the lining cover and the inner cover, and there is no need to open an additional air outlet on the outer cover, which is beneficial to ensuring the aesthetics of the pot cover assembly.

[0033] 9. A covering gap is formed between the pot lid assembly and the pot body assembly, and the covering gap is formed as a peripheral air outlet connected to the air duct cavity, so that the wind in the air duct cavity eventually flows out through the peripheral air outlet to form a cooling cycle; and the height of the covering gap formed between the rear end of the pot lid assembly and the pot body assembly is greater than the height of the covering gap formed between the front end of the pot lid assembly and the pot body assembly, so that the wind in the air duct cavity flows out more from the rear end of the peripheral air outlet to avoid scalding the user by the outflowing high-temperature airflow.

[0034] 10. By setting a first fan on the pot cover assembly and a second fan on the pot body assembly, the two can work together to quickly cool down the pot, thereby achieving the purpose of rapid pressure reduction without exhaust after cooking. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the scheme of the present invention will be further described below. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0056] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0057] Reference Figures 1 to 16As shown, some embodiments of the present invention provide a pot cover assembly 1 of a cooking utensil, which can be covered on a pot body assembly 2 of the cooking utensil to form a cooking cavity for cooking food therebetween.

[0058] Specifically, refer to Figure 1 and Figure 11 As shown, the pot cover assembly 1 can be hinged to the pot body assembly 2, so that the pot cover assembly 1 and the pot body assembly 2 form an integrated cooking utensil. Of course, the pot cover assembly 1 can also be detachably provided with the pot body assembly 2, so that the pot cover assembly 1 and the pot body assembly 2 form a split cooking utensil.

[0059] Reference Figure 2 and Figure 12 As shown, some embodiments of the present invention provide a pot lid assembly 1 for a cooking utensil, comprising an outer lid 11 and an inner lid 12. The outer lid 11 serves as the exterior component of the pot lid assembly 1 and may also be referred to as a surface cover; the inner lid 12 serves as the pressure-bearing component of the pot lid assembly 1 and is generally made of metal, and may also be referred to as a pressure-bearing cover or steel cover.

[0060] Specifically, refer to Figure 1 、 Figure 2 、 Figure 11 and Figure 12 As shown, a first air inlet 111 is provided on the outer cover 11, and a first fan 14 is provided between the outer cover 11 and the inner cover 12. The first fan 14 is provided corresponding to the first air inlet 111, and an air duct cavity 15 is formed between the outer cover 11 and the inner cover 12, and the air outlet of the first fan 14 is provided toward the air duct cavity 15.

[0061] With such an arrangement, when the cooking utensil needs to open its lid, cooling air can be blown into the air duct cavity 15 through the first fan 14 to quickly take away the heat of the inner lid 12, lower the temperature of the inner lid 12, thereby lowering the steam temperature in the pot and reducing the air pressure in the pot, thereby achieving the purpose of no exhaust and pressure reduction and quick lid opening.

[0062] In a specific implementation, the air inlet (or air suction port) of the first fan 14 can be set near the first air inlet 111, and the air outlet of the first fan 14 is set toward the air duct cavity 15, so that when the first fan 14 is working, the air with a relatively low external temperature can be sucked into the first fan 14 through the first air inlet 111, and then blown into the air duct cavity 15 through the air outlet of the first fan 14, so as to dissipate heat and cool down the inner cover 12 with a higher temperature and the steam in the pot.

[0063] It should be understood that in order to improve the safety of the cooking appliance, a float assembly 13 is usually provided on the inner cover 12. When the pressure inside the cooking appliance is increased, the float assembly 13 will be pushed up by the steam in the pot, and the pot cover assembly 1 cannot be turned to open the lid. After cooking is completed, it is necessary to wait for the float assembly 13 on the pot cover to fall before opening the lid.

[0064] In order to achieve the purpose of quick opening, refer to Figure 2 and Figure 12 As shown, in the pot cover assembly 1 provided by some embodiments of the present invention, a float assembly 13 is provided on the inner cover 12 , and a portion of the float assembly 13 is located in the air duct cavity 15 .

[0065] With such arrangement, when the first fan 14 blows cooling air into the air duct cavity 15, the cooling air can be blown to the float assembly 13, thereby cooling the inner cover 12 and the steam in the pot while quickly reducing the temperature of the float assembly 13 and the steam around the float assembly 13, so that the air pressure around the float assembly 13 drops, and the float assembly 13 falls in time, so that the lid can be opened quickly after the float assembly 13 falls, thereby solving the problem that the float on the pot lid cannot react quickly, resulting in the pressure in the pot being reduced to the pressure at which the lid can be opened but the lid still cannot be opened, thereby improving the user experience.

[0066] In a specific implementation, a mounting hole for mounting the float assembly 13 can be provided on the inner cover 12. The float assembly 13 can be mounted at the mounting hole so as to float up and down. The upper end of the float assembly 13 can extend out of the mounting hole and extend into the air duct cavity 15 formed between the outer cover 11 and the inner cover 12, so that the float assembly 13 is partially located in the air duct cavity 15 formed between the outer cover 11 and the inner cover 12, so that when the first fan 14 blows cooling air into the air duct cavity 15, the hot steam around the float assembly 13 can be cooled more effectively, thereby ensuring that the float falls quickly; at the same time, while quickly cooling the area around the float assembly 13, the condensed water generated can also flush the float assembly 13 and the inner cover area near it, thereby preventing food residues accumulated here from adhering to the float assembly 13, causing the float assembly 13 to be unable to fall, and thus the cover cannot be opened.

[0067] In a specific implementation, a mounting hole can be provided on the outer cover 11 for the float assembly 13 to partially pass through, that is, the upper end of the float assembly 13 can partially extend to the mounting hole on the outer cover 11, so that the upper end of the float assembly 13 can be exposed through the mounting hole on the outer cover 11, so that the user can observe the floating state of the float assembly 13.

[0068] Of course, the specific arrangement structure of the float assembly 13 is not limited to the above-mentioned limitation, as long as the float assembly 13 can be installed on the inner cover 12 so as to float up and down, and the cover cannot be opened when the float assembly 13 is lifted up, and the cover can be opened when the float assembly 13 is lowered.

[0069] The pot cover assembly 1 of the cooking utensil provided by the above embodiment of the present invention is provided with a first air inlet 111 on the outer cover 11, a first fan 14 is provided between the outer cover 11 and the inner cover 12, and an air duct cavity 15 is formed between the outer cover 11 and the inner cover 12. The air outlet of the first fan 14 is arranged toward the air duct cavity 15, so that cooling air is blown into the air duct cavity 15 by the first fan 14, quickly taking away the heat of the inner cover 12, reducing the temperature of the inner cover 12, thereby reducing the steam temperature in the pot, reducing the air pressure in the pot, and achieving the purpose of no exhaust and pressure reduction; a float assembly 13 is provided on the inner cover 12, and the float assembly The first fan 14 can blow cooling air into the air duct cavity 15, so that the cooling air can be blown to the float assembly 13, thereby cooling the inner cover 12 and the steam in the pot while quickly reducing the temperature of the float assembly 13 and the steam around the float assembly 13, so that the air pressure around the float assembly 13 drops, and the float assembly 13 falls in time, so that the lid can be opened quickly after the float assembly 13 falls, thereby solving the problem that the float on the pot lid cannot react quickly, resulting in the pressure in the pot being reduced to the pressure where the lid can be opened but the lid cannot be opened, thereby improving the user experience.

[0070] In order to achieve that the cooling air blown by the first fan 14 can be blown to the float assembly 13 more effectively, in some embodiments, referring to Figure 5 、 Figure 6 、 Figure 13 and Figure 14 As shown, the float assembly 13 can be arranged adjacent to the first fan 14, and the float assembly 13 can be arranged in an area formed by the air outlet of the first fan 14 extending along the central axis direction of the first fan 14. That is, the float assembly 13 can be arranged directly opposite or as directly opposite as possible to the air outlet of the first fan 14, so that the first fan 14 can blow cooling air directly toward the float assembly 13.

[0071] Of course, in a specific implementation, due to limitations of the mounting structure, etc., it may not be possible to set the float assembly 13 completely opposite the air outlet of the first fan 14. The float assembly 13 can be slightly deviated from the air outlet of the first fan 14, but the mounting position of the float assembly 13 on the inner cover 12 is relatively close to the position of the first fan 14, so that the cooling air blown out by the first fan 14 can dissipate heat and cool the float assembly 13 in a timely manner.

[0072] It should be noted that for cooking appliances with a separate lid assembly 1 and pot body assembly 2, the inner lid 12 and outer lid 11 of the lid assembly 1 are relatively fixed. During use, the lid assembly 1 and pot body assembly 2 are locked or unlocked by rotating the lid assembly 1 as a whole. In this solution, the float assembly 13 on the inner lid 12 is relatively fixed in position within the air duct cavity 15. That is, the float assembly 13 and the fan are relatively fixed in position. Simply by placing the float assembly 13 within the area extending from the air outlet of the first fan 14 along the central axis of the first fan 14, the first fan 14 can blow cooling air directly toward the float assembly 13.

[0073] For a cooking appliance in which the pot lid assembly 1 and the pot body assembly 2 are hingedly connected as one, the inner cover 12 of the pot lid assembly 1 can rotate relative to the outer cover 11. During use, the pot lid assembly 1 and the pot body assembly 2 are locked or unlocked by rotating the inner cover 12, that is, the inner cover 12 has a locked position and an unlocked position. In this solution, the position of the float assembly 13 on the inner cover 12 in the air duct cavity 15 is not fixed, that is, the position of the float assembly 13 and the fan is not fixed. Because the pot lid assembly 1 and the pot body assembly 2 are in a locked state during cooking, it is necessary to ensure that at least part of the float assembly 13 is located within the area formed by the air outlet of the first fan 14 extending along the central axis of the first fan 14 when the inner cover 12 is in the locked position, thereby ensuring that the first fan 14 can use it to blow cooling air directly toward the float assembly 13 after cooking.

[0074] For example, referring to Figure 5 、 Figure 6 and Figure 7 As shown, the outer cover 11 is provided with a handle 19, which is connected to the inner cover 12. The inner cover 12 has a locked position and an unlocked position. By rotating the handle 19, the inner cover 12 can be driven to rotate switchably between the locked position and the unlocked position relative to the outer cover 11. When the inner cover 12 rotates, the float assembly 13 is driven to rotate together. Figure 6 and Figure 7 As shown, when the inner cover 12 is in the locked position, the float assembly 13 is in the position as shown in FIG. Figure 6 and Figure 7 When the inner cover 12 is in the unlocked position, the float assembly 13 is in the position shown; Figure 6 and Figure 7 In order to achieve effective cooling of the float assembly 13, at least when the inner cover 12 is in the locked position, that is, at least when the float assembly 13 is in the position shown in FIG. Figure 6 and Figure 7 In the position a shown, the float assembly 13 is partially located in a region formed by the air outlet of the first fan 14 extending along the central axis of the first fan 14 .

[0075] It should be noted that, in a specific implementation, the float assembly 13 can be arranged directly opposite the air outlet of the first fan 14, or it can be appropriately deviated from the air outlet of the first fan 14. When an air guide structure is provided in the air duct cavity 15, the position of the float assembly 13 can also be set accordingly according to the air guide structure in the air duct cavity 15. In addition, the float assemblies 13 set at different positions can be tested to better ensure that when the temperature in the pot reaches the temperature at which the lid can be opened, the float assembly 13 just falls, thereby achieving a good match between the lid opening temperature in the pot and the fall of the float assembly 13, so as to ensure the safety of opening the lid while achieving rapid lid opening.

[0076] In some embodiments, reference Figure 4 and Figure 13 As shown, the first fan 14 is vertically disposed between the outer cover 11 and the inner cover 12 , and the central axis of the first fan 14 is perpendicular to the central axis of the inner cover 12 .

[0077] It should be noted that the above-mentioned embodiment states that "the first fan 14 is vertically disposed between the outer cover 11 and the inner cover 12" with reference to the cooking utensil being placed normally with the pot cover assembly 1 covering the pot body assembly 2. In this placement, the central axis of the inner cover 12 of the pot cover assembly 1 is in a vertical position, the central axis of the first fan 14 is perpendicular to the central axis of the inner cover 12, and the central axis of the first fan 14 is in a horizontal position. This arrangement allows the cooling air blown out by the first fan 14 to flow horizontally in the air duct cavity 15, allowing the cooling air to flow along the top surface of the inner cover 12, reducing wind resistance, increasing the contact area between the cooling air and the inner cover 12, and improving heat dissipation efficiency.

[0078] Of course, in actual implementation, taking into account factors such as installation space, first fan 14 is not limited to being vertically positioned between outer cover 11 and inner cover 12. It can also be tilted at a certain angle, but the angle relative to the horizontal direction is preferably greater than 45 degrees. That is, first fan 14 is tilted between outer cover 11 and inner cover 12, and the angle between the central axis of first fan 14 and the central axis of inner cover 12 is greater than 45 degrees. The specific tilt angle of first fan 14 is not limited here and can be appropriately set according to actual circumstances.

[0079] In some embodiments, reference Figures 4 to 6 、 Figures 13 to 15 As shown, an installation space is formed between the outer cover 11 and the inner cover 12, which is located in the peripheral area of the inner cover 12, and the first fan 14 is disposed in the installation space. In other words, the first fan 14 is disposed in the peripheral area of the inner cover 12, which can fully utilize the installation space in the peripheral area of the inner cover 12. Compared with installing the fan in the top area of the inner cover 12, the first fan 14 can be installed on the pot cover assembly 1 without increasing or increasing the overall height of the pot cover assembly 1 too much.

[0080] In a specific implementation, the inner cover 12 is generally configured as a circular cover that matches the shape and size of the inner pot 22 of the pot body assembly 2, while the outer cover 11 is generally configured as an oval cover, a circular cover, or a square cover that is larger than the inner cover 12. In this way, an installation space is formed between the outer cover 11 and the inner cover 12, which is located in the peripheral area of the inner cover 12. Specifically, the installation space can be located at the rear end, the front end, or a corner of the pot cover assembly 1. In other words, the first fan 14 can be located at the rear end, the front end, or a corner of the pot cover assembly 1.

[0081] For example, referring to Figure 4 and Figure 13 As shown, the hinge position of the pot cover assembly 1 and the pot body assembly 2 is located at the rear end of the pot cover assembly 1. In order to arrange the hinge structure at the rear end of the pot cover assembly 1, the installation space formed between the outer cover 11 and the inner cover 12 of the pot cover assembly 1 at the rear end of the pot cover assembly 1 is relatively large. In a specific implementation, the first fan 14 can be set in the installation space behind the inner cover 12.

[0082] In some embodiments, reference Figure 4 and Figure 13 As shown, the inner cover 12 has a front end and a rear end that are opposite to each other in the front-to-back direction. The first fan 14 is disposed in the rear end region of the inner cover 12, with the air outlet of the first fan 14 facing the front end of the inner cover 12. This arrangement not only fully utilizes the space in the rear end region of the inner cover 12 for installing the first fan 14, but also allows the cooling air blown by the first fan 14 to cool the entire surface of the inner cover 12 as it blows from the back to the front, thereby improving heat dissipation efficiency.

[0083] In order to achieve the installation of the first fan 14 between the outer cover 11 and the inner cover 12, a lining cover 16 or a fixed bracket 18 can be set between the outer cover 11 and the inner cover 12, the first fan 14 can be installed on the lining cover 16 or the fixed bracket 18, and the first fan 14 can be used to blow cooling air into the air duct cavity 15 formed between the outer cover 11 and the inner cover 12.

[0084] In some embodiments, reference Figures 2 to 6 As shown, the pot cover assembly 1 of the cooking utensil further includes a lining cover 16 , which is disposed between the outer cover 11 and the inner cover 12 ; the lining cover 16 surrounds and covers the inner cover 12 , and an air duct cavity 15 is formed between the lining cover 16 and the inner cover 12 .

[0085] By configuring in this way, a relatively closed air duct cavity 15 is formed between the lining cover 16 and the inner cover 12, and the cooling air blown out by the first fan 14 is confined to the interlayer formed between the lining cover 16 and the inner cover 12, so that the cooling air can be better utilized to cool the inner cover 12 and the steam in the pot; in addition, by configuring the lining cover 16, the outer cover 11 can also be isolated to avoid the outer cover 11 from being too hot during cooking.

[0086] In the specific implementation, refer to Figures 2 to 6 As shown, the lining cover 16 may include a lining cover plate 161, which may be arranged on the top of the inner cover 12, that is, the lining cover plate 161 may be arranged on the side of the inner cover 12 facing away from the cooking cavity, and be separated between the outer cover 11 and the inner cover 12, and the peripheral edge of the lining cover plate 161 surrounds and covers the inner cover 12 to form an air duct cavity 15 between the lining cover plate 161 and the inner cover 12.

[0087] Continue to refer to Figures 2 to 6 As shown, the lining cover 16 may further include an inner lining ring 162, which may be arranged between the circumferential edge of the outer cover 11 and the circumferential edge of the inner cover 12. During specific assembly, the inner cover 12 may be first assembled onto the inner lining ring 162 from the side of the inner lining ring 162 facing the cooking cavity. The circumferential edge of the inner cover 12 is provided with snap teeth, and the snap teeth provided on the circumferential edge of the inner cover 12 are located on the side of the inner lining ring 162 facing the cooking cavity so as to be rotatably engaged with the pot teeth on the pot body assembly 2. The middle area of the inner cover 12 is exposed on the side of the inner lining ring 162 facing away from the cooking cavity through the middle through hole of the inner lining ring 162.

[0088] In a specific implementation, the circumferential edge of the lining cover plate 161 can be connected and fixed to the inner lining ring 162. Specifically, the lining cover plate 161 can be fixed to the inner lining ring 162 by screwing or snap-fit connection, or the lining cover 16 can be fixed to the inner lining ring 162 by snap-fit connection combined with screw fixation, and the circumferential edge of the lining cover plate 161 surrounds and covers the inner cover 12. Specifically, the circumferential edge of the lining cover plate 161 can surround and cover the area of the inner cover 12 exposed through the central through hole of the inner lining ring 162 to form an air duct cavity 15 between the lining cover plate 161 and the inner cover 12.

[0089] In the specific implementation, refer to Figures 2 to 6As shown, the first fan 14 can be installed on the lining cover plate 161. Specifically, a fan mounting portion 1611 can be provided on the lining cover plate 161, and the first fan 14 can be mounted on the fan mounting portion 1611 to achieve the installation of the first fan 14 on the lining cover plate 161. It should be noted that in order to achieve the installation of the first fan 14 on the lining cover plate 161, the fan mounting portion 1611 on the lining cover plate 161 can protrude from other parts of the lining cover plate 161 so that there is enough space to install the first fan 14. In a specific implementation, the first fan 14 can be installed at the rear end of the lining cover plate 161.

[0090] Of course, in a specific implementation, the lining cover plate 161 and the inner lining ring 162 can also form an integrated lining cover 16 structure, and the inner cover 12 is installed on the side of the integrated lining cover 16 facing the cooking cavity, and a duct cavity 15 is formed between the side surface of the lining cover 16 facing away from the cooking cavity and the inner cover 12.

[0091] In some embodiments, reference Figure 5 and Figure 7 As shown, the lining cover 16 is provided with a wind guide rib 1612 on one side of the surface facing the inner cover 12. The wind guide rib 1612 is located on the air outlet side of the first fan 14. The wind guide rib 1612 is formed into an eight-shaped structure that gradually extends away from the first fan 14 in the direction away from the first fan 14 to divide and guide the wind blown out by the first fan 14 so that it flows around the inner cover 12. Figure 7 The arrows shown indicate the flow direction of the cooling air.

[0092] By configuring in this manner, the wind guide ribs 1612 are used to divide and guide the wind blown out by the first fan 14 so as to flow around the inner cover 12 , thereby increasing the contact area between the cooling wind and the inner cover 12 and achieving more effective cooling of the inner cover 12 .

[0093] In a specific implementation, the first fan 14 can be arranged in the rear end area of the inner cover 12, or the first fan 14 can be installed at the rear end of the lining cover 16, and the air outlet of the first fan 14 is facing the front end of the lining cover 16. In this way, the eight-shaped air guide ribs 1612 can be used to divide and guide the wind blown out by the first fan 14, so that it flows around the inner cover 12 and flows to the front end area of the inner cover 12, thereby realizing heat dissipation and cooling of the entire top surface of the inner cover 12 from back to front, which is beneficial to improving the heat dissipation effect.

[0094] Of course, in a specific implementation, the first fan 14 is not limited to being set in the rear end area of the inner cover 12. For the case where the first fan 14 is set in other areas between the outer cover 11 and the inner cover 12, the cooling air can also be arranged around the inner cover 12 to cool and dissipate heat by setting an eight-shaped air guide rib 1612.

[0095] In some embodiments, reference Figure 8 As shown, the pot cover assembly 1 of the cooking utensil also includes a lining cover 16, which is at least partially located between the circumferential edge of the outer cover 11 and the circumferential edge of the inner cover 12; a first air outlet gap 163 is formed between the circumferential edge of the inner cover 12 and the circumferential edge of the lining cover 16, and the first air outlet gap 163 is connected to the air duct cavity 15.

[0096] It should be noted that the lining cover 16 in this embodiment can be the inner lining ring 162 described in the above embodiment, or it can be the lining cover 16 structure formed by the inner lining ring 162 and the lining cover plate 161 described in the above embodiment. Specifically, the inner lining ring 162 and the lining cover plate 161 can be a split structure or an integrated structure.

[0097] It is configured in this way so that the cooling air blown out by the first fan 14 can flow out from the first air outlet gap 163 between the lining cover 16 and the inner cover 12 after cooling the inner cover 12, thereby ensuring the rapid circulation of the cooling air in the air duct cavity 15, which is beneficial to improving the heat dissipation efficiency; in addition, the air is discharged from the first air outlet gap 163 formed between the lining cover 16 and the inner cover 12, and there is no need to open an additional air outlet on the outer cover 11, which is beneficial to ensuring the aesthetics of the pot cover assembly 1.

[0098] In the specific implementation, refer to Figures 2 to 9 As shown, the lining cover 16 may include an inner lining ring 162, which may be disposed between the peripheral edge of the outer cover 11 and the peripheral edge of the inner cover 12. During assembly, the inner cover 12 may be first assembled onto the inner lining ring 162 from the side of the inner lining ring 162 facing the cooking cavity. The peripheral edge of the inner cover 12 is provided with snap teeth, which are located on the side of the inner lining ring 162 facing the cooking cavity so as to be rotatably engaged with the pot teeth on the pot body assembly 2. The central area of the inner cover 12 is exposed on the side of the inner lining ring 162 facing away from the cooking cavity through the central through hole of the inner lining ring 162; and, referring to FIG. Figure 2 and Figure 8 As shown, a first air outlet gap 163 is formed between the peripheral edge of the inner cover 12 and the peripheral edge of the inner lining ring 162 , and the first air outlet gap 163 is connected to the air duct cavity 15 .

[0099] In some embodiments, reference Figure 8 and Figure 9 As shown, a plurality of air outlet grooves 1621 are arranged at intervals on the circumferential edge of the inner liner 162. The air outlet grooves 1621 can be formed by the inner peripheral wall surface of the circumferential edge of the inner liner 162 being recessed toward the outer peripheral wall surface. The air outlet grooves 1621 are connected to the first air outlet gap 163.

[0100] In a specific implementation, the number of the air outlet grooves 1621 can be multiple, and the multiple air outlet grooves 1621 are arranged at intervals along the circumference of the inner liner 162. By providing the air outlet grooves 1621, the cooling air blown by the first fan 14 can flow out more quickly after dissipating heat and cooling the inner cover 12, thereby reducing wind resistance.

[0101] In other embodiments, referring to Figures 11 to 16 As shown, the pot cover assembly 1 of the cooking appliance further includes a fixing bracket 18 . The fixing bracket 18 is disposed between the outer cover 11 and the inner cover 12 , and the first fan 14 is mounted on the fixing bracket 18 .

[0102] In this embodiment, compared to the aforementioned embodiment in which lining cover plate 161 is provided, lining cover plate 161 can be eliminated. Instead, a fixing bracket 18 is provided between outer cover 11 and inner cover 12 to facilitate installation of first fan 14 therebetween. The primary difference from the embodiment in which lining cover plate 161 is that the cooling air blown by first fan 14 flows between outer cover 11 and inner cover 12, rather than through the interlayer formed between lining cover plate 161 and inner cover 12. Using fixing bracket 18 to install first fan 14 simplifies the overall structure of pot lid assembly 1 compared to the embodiment in which lining cover plate 161 is provided, thereby reducing costs.

[0103] It should be noted that, in a specific implementation, the fixing bracket 18 can be disposed on the side of the inner liner 162 facing away from the cooking cavity and fixedly connected to the inner liner 162. Specifically, the fixing bracket 18 can be disposed at the rear end of the inner liner 162 to ensure that the cooling air blown by the first fan 14 flows from the back to the front. Alternatively, an eight-shaped air guide rib 1612 can be disposed on the side of the fixing bracket 18 facing the inner cover 12 to divide and guide the air blown by the first fan 14 so that it fully surrounds the inner cover 12 for cooling and heat dissipation.

[0104] Reference Figure 1 and Figure 11 As shown, other embodiments of the present invention provide a cooking utensil, comprising a pot body assembly 2 and a pot cover assembly 1 of the cooking utensil according to any of the above embodiments, wherein the pot cover assembly 1 can be opened and closed to cover the pot body assembly 2.

[0105] The cooking utensil provided in the embodiment of the present invention includes the pot cover assembly 1 of any of the above embodiments, and thus has the beneficial effects of the pot cover assembly 1 of any of the above embodiments, which will not be described in detail here.

[0106] In some embodiments, reference Figure 1 and Figure 11As shown, a cover gap is formed between the pot lid assembly 1 and the pot body assembly 2, and the cover gap is formed into a peripheral air outlet 17 connected to the air duct cavity 15. This arrangement allows the air in the air duct cavity 15 to eventually flow out through the peripheral air outlet 17, forming a cooling cycle.

[0107] In a specific embodiment, the height of the gap formed between the rear end of the pot lid assembly 1 and the pot body assembly 2 is greater than the height of the gap formed between the front end of the pot lid assembly 1 and the pot body assembly 2. This arrangement allows more air in the air duct cavity 15 to flow out from the rear end of the peripheral air outlet 17, thereby preventing the user from being burned by the high-temperature air flow.

[0108] Of course, in a specific implementation, the height of the covering gap formed between the rear end portion of the pot cover assembly 1 and the pot body assembly 2 can also be set to be equal to the height of the covering gap formed between the front end portion of the pot cover assembly 1 and the pot body assembly 2, so that the air outlet when the pot cover assembly 1 and the pot body assembly 2 are covered is more uniform and more aesthetically pleasing.

[0109] In a specific embodiment, referring to Figure 2 As shown, the rear end of the outer cover 11 is provided with a first air inlet 111, the first fan 14 is vertically arranged in the rear end area of the inner cover 12, and the air outlet of the first fan 14 is directed toward the front end of the inner cover 12, and a lining cover plate 161 is provided between the inner cover 12 and the outer cover 11 to surround and cover the inner cover 12, so as to form a sandwich-shaped air duct cavity 15 between the inner cover 12 and the lining cover plate 161, and a first air outlet is provided between the peripheral edge of the inner cover 12 and the peripheral edge of the inner lining ring 162. The gap 163 forms a peripheral air outlet 17 at the covering surface of the pot cover assembly 1 and the pot body assembly 2; the cooling air blown out by the first fan 14 flows from back to front through the interlayer formed between the inner cover 12 and the lining cover plate 161, surrounds the inner cover 12 to dissipate heat, and then flows out of the pot cover assembly 1 through the first air outlet gap 163 formed between the inner cover 12 and the inner lining ring 162, and finally flows out through the peripheral air outlet 17 formed at the covering surface of the pot cover assembly 1 and the pot body assembly 2, thereby realizing a cooling cycle.

[0110] In some embodiments, reference Figure 1 、 Figure 10 、 Figure 11 and Figure 16 As shown, the pot body assembly 2 includes a pot body 21 and an inner pot 22 placed in the pot body 21; a second air inlet 211 is provided on the side wall of the pot body 21, and a second fan 23 corresponding to the second air inlet 211 is provided on the pot body 21, a second air outlet gap 24 is formed between the top periphery of the pot body 21 and the top periphery of the inner pot 22, and / or a bottom air outlet 212 is provided at the bottom of the pot body 21.

[0111] In this way, the second fan 23 provided on the pot body assembly 2 can dissipate heat and cool down the inner pot 22 and the steam in the pot, thereby cooperating with the first fan 14 provided on the pot cover assembly 1 to achieve the purpose of quickly cooling down the steam in the pot, so as to more quickly reduce the temperature of the steam in the pot, reduce the air pressure in the pot, and achieve the purpose of reducing pressure without exhaust.

[0112] That is to say, by respectively arranging air cooling systems on the pot lid assembly 1 and the pot body assembly 2 of the cooking utensil, a double air cooling system is realized, and the pressure reduction is not limited by the amount of food. In the case of a large amount of food, the first fan 14 can be used to dissipate heat and cool down the inner lid 12 and the steam in the pot, and at the same time, the second fan 23 can be used to dissipate heat and cool down the inner pot 22 and the steam in the pot, so as to quickly take away the heat and achieve the purpose of quickly opening the lid.

[0113] After testing, it was found that the cooking utensil provided by the embodiment of the present invention can realize one cup of rice porridge with the lid opened quickly within 5 minutes without exhausting, avoiding disturbance and shortening waiting time, thus improving the user experience.
