Description

TECHNICAL FIELD

[0001] The utility model belongs to kitchen appliance technical field, concretely relates to a pot cover subassembly and pressure cooking utensil. BACKGROUND

[0002] Pressure cooking utensil is usually provided with exhaust valve and float valve on inner cover, wherein, float valve can float up and down under the push of gas in the pot, and is used for discharging cold gas in the pot before upper pressure, and float up to seal when upper pressure in the pot.

[0003] However, the top wall of inner cover is often uneven, which leads to difficulty in setting exhaust valve and float valve, both installation hole structure is not easy to be processed in uneven area, and sealing difficulty between exhaust valve, float valve and installation hole is increased, leading to poor sealing stability at both, and gas leakage is easy to occur.

[0004] In addition, a small amount of liquid such as rice soup will overflow from exhaust valve to the surface of inner cover during the exhaust process of exhaust valve, and the liquid will further flow to the float valve, thereby causing the float valve to adhere to the inner cover, so that the float valve cannot normally float and fails.

[0005] Furthermore, in order to prevent overflow during exhaust, the exhaust valve is generally eccentrically arranged on the inner cover in the prior art, and the pressure cooking utensil needs to horizontally rotate the pot cover before and after cooking to lock and unlock the pot cover and the pot body, so that the movement track of the exhaust valve is an arc when the pot cover rotates, so as to ensure the sealing property of the installation port on the inner cover for installing the exhaust valve, and avoid relative movement between the exhaust valve and the inner cover. Only the pot cover can be designed as a structure that can be rotated as a whole, which leads to large weight and volume of the rotatable part, and the user is more laborious when operating. At the same time, since the pot cover can be rotated as a whole with respect to the pot body, the pot cover and the pot body are made into a split structure, so that the pot cover can be removed from the pot body, and the pot cover and the pot body cannot be connected. Therefore, after opening the cover, the storage of the pot cover becomes a difficult problem for the user, and if a storage structure is added to the pot body, the product structure difficulty and manufacturing cost will be greatly increased.

In the description of the present application, the description of the terms "embodiment", "example", "one embodiment", "example" or "specific example" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In the present application, the illustrative description of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0046] As shown in Figure 3 , Figure 5 , Figure 6 A lid assembly 1, including a cover body 11 and an inner cover 12 placed below the cover body 11, the inner cover 12 cooperates with the pot body 6 to form a cooking cavity, the center area of the top surface of the inner cover 12 is provided with a sunken first sunken table 121, the outer side of the first sunken table 121 is provided with a second sunken table 122, the first sunken table 121 is provided with an exhaust valve 123, the second sunken table 122 is provided with a float valve 124, and the sinking height of the first sunken table 121 is greater than the sinking height of the second sunken table 122.

[0047] It should be noted that the shape of the second sunken platform 122 is not limited, in an embodiment, as shown in Figure 5 、 Figure 6 , the second sunken platform 122 is located on one side of the first sunken platform 121. In another embodiment, the second sunken platform 122 is a ring structure, and surrounds the outer periphery of the first sunken platform 121.

[0048] In the utility model, the inner cover 12 top surface is provided with the first sunken platform 121 and the second sunken platform 122, the first sunken platform 121 is located in the central region of the inner cover 12, the second sunken platform 122 is located on the outer side of the first sunken platform 121, that is, eccentrically arranged in the inner cover 12, wherein the exhaust valve 123 is arranged in the first sunken platform 121, and the float valve 124 is arranged in the second sunken platform 122. Due to the arrangement of the sunken platform structure, the inside of the first sunken platform 121 and the second sunken platform 122 is more flat compared with other regions of the inner cover 12 top surface, and then the mounting hole and other mounting structures for various valve installation are more conveniently processed, and the sealing difficulty of each valve installation place is greatly reduced, which helps to improve the installation stability and sealing reliability of the exhaust valve 123 and the float valve 124.

[0049] At the same time, due to the eccentric arrangement of the second sunken platform 122 and the inner cover 12, the float valve 124 is closer to the edge of the inner cover 12, and the float valve 124 is also matched with the stop opening structure on the pot cover assembly 1. Specifically, when the float valve 124 is in the floating state, it indicates that the pot is in a high pressure state, at this time, the float valve 124 and the stop opening structure form a stop, so that at least part of the area of the pot cover assembly 1 cannot rotate and unlock with the pot body 6. When the float valve 124 is in the sinking state, the stop opening structure is avoided, and at this time, the pot cover assembly 1 can rotate and unlock with the pot body 6.

[0050] In addition, as shown in Figure 7 , the sinking height H1 of the first sunken platform 121 is greater than the sinking height H2 of the second sunken platform 122, so that the first sunken platform 121 is lower than the second sunken platform 122, so that even if the liquid overflows from the exhaust valve 123, due to the higher position of the second sunken platform 122, the liquid is difficult to enter the second sunken platform 122, and it is also difficult to reach the float valve 124, and can only be temporarily stored in the first sunken platform 121, so that the cleaning of the float valve 124 is greatly improved, the risk of the liquid overflowed from the exhaust valve 123 adhering to the float valve 124 is reduced, and the stable and reliable work of the float valve 124 is ensured.

[0051] Further, since the first sink 121 is located in the central region of the inner cover 12, the exhaust valve 123 can be correspondingly arranged in the center of the inner cover 12. Thus, for the pressure cooking utensil, when the inner cover 12 rotates horizontally, the rotation center coincides with the center of the exhaust valve 123, so that the exhaust valve 123 rotates in place without changing position, and thus the pot cover assembly 1 does not need to rotate as a whole, but only the inner cover 12 or other parts need to be rotatable. Thus, the cover body 11 can be designed as a structure connected to the pot body 6, so that it does not need to be removed from the pot body 6, and thus the user does not need to separately store the pot cover assembly 1 after opening, which greatly improves the user experience.

[0052] Preferably, as shown in Figure 5 , the bottom walls of the first sink 121 and the second sink 122 are provided with mounting planes, and the exhaust valve 123 and the float valve 124 are arranged on the mounting planes. The planar structure is easier to process the mounting port for mounting the float valve 124 and the exhaust valve 123, thereby reducing the processing difficulty, and the planar structure makes the sealing between the mounting port and the float valve 124 and the exhaust valve 123 easier, which can ensure the sealing reliability.

[0053] Further, as shown in Figure 7 , a barrier rib 127 protruding upward is arranged between the first sink 121 and the second sink 122. The arrangement of the barrier rib 127 can improve the blocking effect of the liquid in the first sink 121, further increasing the difficulty of the liquid in the first sink 121 entering the second sink 122.

[0054] As a preferred embodiment of the utility model, as shown in Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , the exhaust valve 123 is arranged in the center of the inner cover 12, one end of the cover body 11 is provided with a connecting portion 113, and the connecting portion 113 is used for rotatingly connecting with the pot body 6, so that the pot cover assembly 1 can be flipped up and down relative to the pot body 6.

[0055] The exhaust valve 123 is arranged in the center of the inner cover 12, and when the inner cover 12 rotates horizontally, the rotation center of the inner cover 12 coincides with the center of the exhaust valve 123, so that the exhaust valve 123 rotates in place without changing position, and thus the cover body 11 can be designed as a non-rotatable structure. When locking and unlocking the pot cover assembly 1 and the pot body 6, only the inner cover 12 or the local parts of the pot cover assembly 1 need to be rotated. Thus, the cover body 11 can be designed as a structure connected to the pot body 6, so that it does not need to be removed from the pot body 6 when opening, but is always connected to the pot body 6. Thus, the user does not need to separately store the pot cover assembly 1 after opening, which greatly improves the user experience. Moreover, it is also convenient for the electrical connection of the electrical elements on the pot cover assembly 1 and the pot body 6, and reduces the design cost of the electrical appliances.

[0056] In a preferred embodiment, as shown in Figure 7 , the pot cover assembly 1 is further provided with an exhaust operating member 4, which comprises an operating button 41 arranged on the cover body 11 and a transmission member 42, one end of which is matched with the operating button 41 and the other end of which extends into the first sunken platform 121 to be matched with the exhaust valve 123.

[0057] The arrangement of the exhaust operating member 4 provides the pot cover assembly 1 with the function of manual exhaust pressure relief. After the pressure cooking is finished, the user can manually press the operating button 41 to drive the operating button 41 to move the transmission member 42, which further drives the exhaust valve 123 to open to perform the exhaust pressure relief.

[0058] The utility model does not limit the movement mode of the transmission member 42. In a preferred embodiment, as shown in Figure 7 , the transmission member 42 is rotationally connected with the cover body 11 to make the transmission member 42 a lever structure, one end of which is below the operating button 41 and can swing downward under the pressing of the operating button 41, and the other end of which extends into the first sunken platform 121 to be matched with the exhaust valve 123. The transmission member 42 and the weight 1231 can be directly matched, that is, the transmission member 42 directly acts on the weight 1231, or they can be indirectly matched, as shown in Figure 7 , the exhaust operating member 4 further comprises a trigger member 43 between the transmission member 42 and the weight 1231, the transmission member 42 drives the trigger member 43 to move, and then the trigger member 43 acts on the weight 1231 to lift the weight 1231.

[0059] Specifically, as shown in Figure 3 , Figure 7 , the exhaust valve 123 comprises an exhaust pipe 1232 and a weight 1231 arranged at the top end of the exhaust pipe 1232, one end of the transmission member 42 can lift the weight 1231 to lose the sealing of the exhaust pipe 1232, so that the gas in the pot is sprayed out through the exhaust pipe 1232.

[0060] Of course, the transmission member 42 can also have other movement modes, for example, the transmission member 42 is slidingly connected with the cover body 11 to make it able to transmit the force of the operating button 41 by translation to drive the weight 1231 to lift.

[0061] The operation button 41 drives the exhaust valve 123 to exhaust through the transmission member 42, the transmission member 42 is rotationally connected to the cover body 11, and one end extends into the first sunken table 121, so that the length of the transmission member 42 is increased, the force arm between the exhaust valve 123 and the transmission member 42 is increased, on the one hand, the transmission member 42 can drive the exhaust valve 123 more easily, and the operation sensitivity is improved, on the other hand, the pressing stroke of the operation button 41 is shortened, the structure of the operation button 41 is simplified, and the operation experience is improved.

[0062] As a preferred embodiment of the utility model, as shown in Figure 3 The cover body 11 is provided with a cooling fan 5, a wind cooling channel 112 in communication with the cooling fan 5 is formed between the upper surface of the cover body 11 and the inner cover 12, and the cooling fan 5 can blow cold air to the surface of the inner cover 12 to cool the inner cover 12.

[0063] The cooling fan 5 can blow cold air into the wind cooling channel 112, so that the cold air contacts the surface of the inner cover 12 to cool the inner cover 12, thereby achieving different effects.

[0064] Specifically, in one embodiment, the cooling fan 5 is started and operated during cooking, the temperature of the inner cover 12 is reduced by cooling the inner cover 12, and then when exhaust, the foam, bubbles and the like in the pot upsurge to the inner cover 12, which will break at low temperature, and then the liquid in the bubbles is separated from the gas, the liquid flows back to the pot, and the gas is discharged upward through the exhaust structure such as the float valve 124, thereby realizing bubble breaking and anti-overflow. In another embodiment, the cooling fan 5 is operated after pressure cooking is completed, the temperature in the pot is reduced by cooling and cooling the inner cover 12, and rapid pressure reduction is achieved. Compared with the exhaust pressure relief mode, the air cooling mode has faster pressure reduction speed and does not produce large air flow noise, which helps to realize rapid opening of the cover and improve the use experience. The first sunken table 121 and the second sunken table 122 on the surface of the inner cover 12 increase the surface area of the inner cover 12, increase the contact area of the cold air flow with the inner cover 12, and improve the cooling efficiency. Of course, the cooling fan 5 can also be operated during cooking and after pressure cooking is completed, so that the pressure cooking appliance realizes the integration of multiple functions and improves the use experience.

[0065] Preferably, as shown in Figure 1 、 Figure 2 The top surface of the cover body 11 is provided with a convex structure 111 protruding upward, and the cooling fan 5 is arranged inside the convex structure 111.

[0066] The convex structure 111 is hollow inside, leaving installation space for the cooling fan 5, and the cooling fan 5 is installed inside the convex structure 111, achieving a hidden design, and compared with the way of arranging the fan inside the pot cover assembly 1, the distance between the cooling fan 5 and the inner cover 12 or the cooking cavity can be increased, thereby reducing the heat transferred to the cooling fan 5, allowing the cooling fan 5 to work at a safe temperature, and improving the service life of the cooling fan 5.

[0067] At the same time, the top surface of the cover body 11 is also provided with a protruding operation handle 2, and the shape of the convex structure 111 can be further arranged to allow the convex structure 111 to form the top modeling of the pot cover assembly 1 together with the operation handle 2, thereby reducing the sense of strangeness caused by the convex structure 111 and improving the aesthetics.

[0068] It should be noted that the present embodiment does not limit the air outlet direction of the cooling fan 5. In one embodiment, the air outlet of the cooling fan 5 faces the top surface of the inner cover 12. The air outlet of the cooling fan 5 faces downward, i.e., the top surface of the inner cover 12, so that the cold air can directly collide with the top surface of the inner cover 12, thereby dispersing along the surface of the inner cover 12, prolonging the contact time of the cold air with the inner cover 12, and improving the cooling effect. In another embodiment, as shown in Figure 3 、 Figure 4 , the air outlet of the cooling fan 5 faces the side surface of the inner cover 12. The cold air enters the air cooling channel 112 horizontally, so that the inner cover 12 does not block the cold air, thereby improving the flow efficiency and heat exchange efficiency of the cold air and avoiding the formation of turbulence in the air cooling channel 112.

[0069] Preferably, as shown in Figure 1 、 Figure 7 , the top surface of the cover body 11 is provided with an operation handle 2, the operation handle 2 has a fixed part 22 located at the center of the cover body 11, and a holding part 21 eccentrically arranged with the cover body 11, the fixed part 22 has a containing cavity 221, and the exhaust valve 123 is contained in the containing cavity 221.

[0070] When the user rotates the operation handle 2 by the holding part 21, the operation handle 2 will rotate around the center of the fixed part 22, i.e., the center of the cover body 11 (the cover body 11 and the inner cover 12 are concentrically arranged). In this way, on the one hand, the rotation center of the operation handle 2 is located on the operation handle 2 itself, and the operation handle 2 moves as a swing of the holding part 21 with the fixed part 22 as the center, the position of the fixed part 22 does not change, and the whole operation handle 2 does not change much in position, saving the space occupied by the operation handle 2 when moving and the operation space of the user, which is more conducive to the operation of the pot cover in a small space and improves the use experience. On the other hand, the holding part 21 is eccentric to the cover body 11 and the inner cover 12, increasing the moment arm between the user's operation position and the rotation center, making the user's operation more labor-saving.

[0071] The exhaust valve 123 is accommodated in the accommodation cavity 221, which can avoid the exhaust valve 123 from protruding too much from the operation handle 2, and help to reduce the overall height of the pot cover, and achieve the design of light and thin. On the other hand, the exhaust valve 123 can be hidden, and the appearance of the pot cover is improved.

[0072] Further, as shown in the drawings, Figure 1 The pot cover assembly 1 further comprises an exhaust cover 3 which is detachably fixed to the fixed part 22 to cover the accommodation cavity 221, and the exhaust cover 3 is provided with an exhaust port 31.

[0073] The exhaust cover 3 can cover the accommodation cavity 221, so as to hide the exhaust valve 123, and the exhaust cover 3 is provided with the exhaust port 31, so that the airflow discharged from the exhaust valve 123 can be sprayed outside through the exhaust port 31. The exhaust cover 3 is designed to be detachable, which is convenient for the user to clean the inside of the accommodation cavity 221.

[0074] Preferably, the exhaust cover 3 rotates with the operation handle 2, so that the relative position between the exhaust port 31 and the holding part 21 remains consistent regardless of the position of the operation handle 2, and the relative positions of the holding position and the exhaust position remain fixed, which greatly reduces the risk of being scalded by the user during operation, and improves the use experience.

[0075] Specifically, as shown in the drawings, Figure 7 The top surface of the cover body 11 is provided with a sunken groove, the fixed part 22 is provided with a protruding structure extending into the sunken groove, and the accommodation cavity 221 is located inside the protruding structure, so as to increase the volume of the accommodation cavity 221, facilitate the installation of the exhaust valve 123, and prevent the overall height of the pot cover from being increased too much, and ensure the design of the whole machine to be small.

[0076] As a preferred embodiment of the present application, as shown in the drawings, Figure 4 , Figure 6 The cover body 11 is further provided with a temperature measuring element 125, and the bottom wall of the first sunken table 121 is provided with a through hole 126, and the temperature measuring element 125 extends into the cooking cavity through the through hole 126.

[0077] Since the first sunken table 121 has a large sinking height, it is closer to the food in the pot. By arranging the temperature measuring element 125 in the first sunken table 121, the temperature measuring element 125 is also closer to the food in the pot, which can improve the sensitivity of the temperature measuring element 125 to the temperature of the food in the pot, improve the sensitivity of temperature measurement, and improve the accuracy of the temperature measuring element 125, and achieve the purpose of accurate temperature measurement.

[0078] The utility model discloses still disclose a kind of pressure cooking utensils, including pot body 6, still including the pot cover assembly 1 of above, pot body 6 is provided with hinged seat, one end of cover body 11 is rotatably connected with hinged seat, and cover body 11 and the connecting place of pot body 6 is provided with damping structure.

[0079] Pot cover assembly 1 is rotatably connected with pot body 6, pot cover assembly 1 can be opened and closed in the way of up-down overturning, not only save the user's annoyance of storing pot cover assembly 1, but also make the opening and closing mode of pressure cooking utensils more close to normal pressure cooking utensils (such as electric rice cooker), and further more conform to the user's usage habit.

[0080] Preferably, the damping structure includes a damper disposed in the hinged seat, the pot cover assembly 1 cooperates with the damper, and the damper is configured to receive a rotational damping force when the pot cover assembly 1 rotates towards a first direction, the first direction being a closing direction.

[0081] The damper itself provides a damping force when the pot cover assembly 1 rotates, which simplifies the connection structure and the number and complexity of components of the damping structure. Moreover, the damping force of the damper is generated between the two parts that rotate relative to each other, and does not directly exert a force on the pot body 6 and the pot cover, thereby reducing the stress on the pot cover and the pot body 6, and greatly reducing the structural strength requirements of the two, thus saving material costs.

[0082] When the user opens the cover, the user needs to actively hold the pot cover assembly 1 and turn it upwards to open it. Since this process is entirely operated by the user, the user can subjectively adjust the force with which the pot cover assembly 1 is turned over, thereby alleviating the problem of excessive turning force of the pot cover assembly 1 upwards causing shaking. When closing the cover, the user does not need to continuously exert a downward pressure on the pot cover assembly 1, but only needs to gently push the pot cover assembly 1 downwards, and the pot cover assembly 1 can automatically and slowly close under the action of its own gravity and the damping force of the damper. Due to the presence of the damping force, the pot cover assembly 1 will not collide with the pot body 6 at a fast speed, thereby reducing the risk of abnormal noise and collision damage. This makes the opening and closing operation of the user more simple, convenient and labor-saving, and improves the user experience.

[0083] Of course, the damping structure can also be other structures, such as a torsional spring, etc., as long as it can provide a damping force to the pot cover assembly 1 during the closing movement of the pot cover assembly 1, so that the pot cover assembly 1 moves more stably, which is not limited herein.
