Description

Technical Field

[0001] The utility model belongs to the technical field of cooking devices, and particularly relates to an open - cover structure of a cooking device and a cooking device. Background Art

[0002] At present, cooking devices are used to cook food. In the prior art, the Chinese utility model patent with the publication number CN217827591U discloses "a cooking device with air - frying and hot - pot functions": including a main body, a concave cavity with an upward opening is formed in the main body, a pot is placed in the concave cavity, and an electric heating plate for heating the pot is arranged at the bottom of the concave cavity; it also includes an upper cover body for closing the pot, the main body and the upper cover body are hinged by a hinge, a motor assembly and an impeller for blowing air into the pot are arranged in the upper cover body, the motor assembly drives the impeller to rotate, a heating element for heating the air flow generated by the operation of the impeller is arranged in the upper cover body, and the upper cover body can be opened to a horizontal state. Thus, the cooking device has two functions of air - frying and hot - pot; when using the hot - pot function, the upper cover body is opened to the horizontal state. Then, when several users surround the cooking device to have a hot - pot, the upper cover body will not interfere with the activities of the users' chopsticks or other tableware. However, for users who do not often use the hot - pot function, when the upper cover body is opened to the horizontal state, it occupies a large area on the kitchen countertop, which is not conducive to the placement of the above - mentioned cooking device. When the user uses the air - frying function, after the air - frying is completed, in fact, the user only needs to open the upper cover body about 90°, and then the food in the concave cavity can be taken out. However, if the other hand does not support the upper cover body, the upper cover body may swing backward due to gravity during opening and collide with other objects placed behind the cooking device (such as a soy sauce bottle, etc.). Therefore, the use of this cooking device is not convenient enough, and it is necessary to improve the open - cover structure of this cooking device. Summary of the Utility Model

[0004] In order to achieve the above - mentioned purpose, the utility model adopts the following technical solutions:

The first limit moving groove and the second limit moving groove are axially and circumferentially offset relative to each other and are in transitional connection at the end. The rotation convex part is arranged to slide between the two limit moving grooves; The first limit moving groove is used to limit the rotation convex part so that the cover body rotates between the closed position and the first open position; When the rotation convex part slides into the second limit moving groove, the second limit moving groove is used to limit the rotation convex part so that the cover body rotates from the first open position to the second open position; The position - switching control structure includes a pressing structure and a reset mechanism; The pressing structure is arranged at the end of the rotating - shaft limit sleeve and is used to drive the rotating - shaft limit sleeve to move axially relative to the rotating - shaft assembly so that when the rotation convex part cooperates with the relative movement of the cover body, it changes positions between the first limit moving groove and the second limit moving groove; The reset mechanism acts on the rotating - shaft limit sleeve and applies a driving force to the rotating - shaft limit sleeve in the direction opposite to the driving direction of the pressing structure.

By operating the position - switching control structure, the rotation convex part of the rotating - shaft assembly can enter and move in the second limit moving groove, so that the cover body can continue to rotate to the second open position. For a cooking device applying the open - cover structure of the cooking device of the present utility model, for example, setting the first open position as the vertical open position and the second open position as the horizontal open position, the upper cover of the cooking device can be limited at the vertical open position or the horizontal open position when opened, and the user does not need to hold the upper cover by hand when using the cooking device, which is convenient to use. When the open - cover structure of the cooking device is in use, the cover body can directly flip from the closed position to the first position.

[0031] See Figures 1 to 12, The opening structure of the cooking device of the present utility model includes a lid body 1, a body 2, and a position switching control structure 3; the lid body 1 is rotatably connected to the body 2, and a circumferentially limiting rotating shaft assembly 4 is provided at the rotation connection part. The rotating shaft assembly 4 is provided with a rotation convex part 41 arranged radially; the body 2 is provided with a rotating shaft limiting sleeve 5 that is matched and installed with the rotating shaft assembly 4. The rotating shaft limiting sleeve 5 is rotatably sleeved outside the rotating shaft assembly 4, so that the lid body 1 can be rotatably covered or opened relative to the body 2; the rotating shaft limiting sleeve 5 is provided with a first limiting moving groove 51 and a second limiting moving groove 52 arranged circumferentially corresponding to the rotation convex part 41. The first limiting moving groove 51 and the second limiting moving groove 52 are axially and circumferentially offset from each other and are transitionally connected at the end. The rotation convex part 42 slides between the two limiting moving grooves 52; the first limiting moving groove 51 is used to limit the rotation convex part 41, so that the lid body 1 rotates between the closed position and the first opening position; when the rotation convex part 41 slides into the second limiting moving groove 52, the second limiting moving groove 52 is used to limit the rotation convex part 41, so that the lid body 1 rotates from the first opening position to the second opening position; the position switching control structure 3 includes a pressing structure and a reset mechanism 32; the pressing structure is arranged at the end of the rotating shaft limiting sleeve 5 and is used to drive the rotating shaft limiting sleeve 5 to move axially relative to the rotating shaft assembly 4, so that when the rotation convex part 41 cooperates with the relative movement of the lid body 1, it changes positions between the first limiting moving groove 51 and the second limiting moving groove 52. The reset mechanism 32 acts on the rotating shaft limiting sleeve 5 and applies a driving force to the rotating shaft limiting sleeve 5 in the direction opposite to the driving direction of the pressing structure.

[0032] Compared with the prior art, for the open - cover structure of the cooking device of the present utility model, by providing a rotating shaft assembly 4 at the rear side of the cover body 1 and a rotating shaft limiting sleeve 5 at the rear side of the body 2, and the rotating shaft limiting sleeve 5 is provided with a first limiting movable groove 51 and a second limiting movable groove 52 arranged circumferentially corresponding to the rotating convex part 41 of the rotating shaft assembly 4, and the first limiting movable groove 51 and the second limiting movable groove 52 are axially and circumferentially offset relative to each other. When the rotating convex part 41 of the rotating shaft assembly 4 moves in the first limiting movable groove 51, the cover body 1 can be switched between the closed position and the first open position. By operating the position - switching control structure 3, the rotating convex part 41 of the rotating shaft assembly 4 can enter and move in the second limiting movable groove 52, so that the cover body 1 can continue to rotate to the second open position. For a cooking device applying the open - cover structure of the cooking device of the present utility model, for example, setting the first open position as the vertical open position and the second open position as the horizontal open position, the upper cover of the cooking device can be limited in the vertical open position or the horizontal open position when opened, and the user does not need to hold the upper cover by hand during use, which is convenient. When the open - cover structure of the cooking device is in use, the cover body 1 can directly flip from the closed position to the first position. Further, by operating the pressing structure, the rotating convex part 41 can be changed from the first limiting movable groove 51 to the second limiting movable groove 52, so that the cover body 1 further flips from the first position to the second position. And through the action of the reset mechanism 32, the rotating convex part 41 can be changed from the second limiting movable groove 52 to the first limiting movable groove 51, so that the cover body 1 directly flips from the second position to the closed position, which is convenient for the user to operate.

[0033] See Figures 5 to 12 , in an embodiment, the rotating shaft limiting sleeve 5 is provided with a clearance area 53 that axially and circumferentially communicates the first limiting movable groove 51 and the second limiting movable groove 52. By pressing the pressing structure, the axial movement of the rotating shaft limiting sleeve 5 can be controlled to make the rotating convex part 41 disengage from any position in the first limiting movable groove 51 and enter the clearance area 53, which makes it more convenient for the user to operate the pressing structure. The reset mechanism 32 is used to drive the rotating convex part 41 to enter the first limiting movable groove 51 from the clearance area 53 when the body 2 rotates to make the rotating convex part 41 disengage from the second limiting movable groove 52 and enter the clearance area 53; by such a setting, on the one hand, only by pressing the pressing structure, the cover body 1 can be further rotated from the first open position to the second position, which is convenient for the user to operate. On the other hand, when the cover body 1 rotates from the second open position to the first open position, when the rotating convex part 41 moves in the second limiting movable groove 52 to the clearance area 53, the reset mechanism 32 can automatically drive the rotating shaft limiting sleeve 5 to reset relative to the rotating shaft assembly 4, so that the rotating convex part 41 automatically falls back into the first limiting movable groove 51, so that the cover body 1 can be quickly closed to the closed state, which is convenient for the user to operate.

[0034] SeeFigures 7 to 10 , in one embodiment, the first limiting activity groove 51 and the second limiting activity groove 52 are respectively communicated with the inner side and the outer side of the rotating shaft limiting sleeve 5. The rotating shaft assembly 4 includes a rotating shaft member 42 and an end cover member 43. The rotating convex portion 41 is arranged on the end cover member 43 and extends radially. A plugging hole 44 is provided at the end of the rotating shaft member 42, and a plugging portion 45 is provided at the bottom of the end cover member 43. The plugging portion 45 and the plugging hole 44 cooperate to assemble the rotating shaft member 42 and the end cover member 43 into the rotating shaft assembly 4. By such arrangement, the rotating shaft assembly 4 includes the separately arranged rotating shaft member 42 and the end cover member 43, which facilitates the assembly of the rotating shaft assembly 4 into the rotating shaft limiting sleeve 5 in a split structure manner, and the assembly operation efficiency is high.

[0035] See Figures 5 to 9 , in one embodiment, the reset mechanism 32 is a reset spring. An axial abutting portion 46 is provided on the outer periphery of the rotating shaft assembly 4. Two ends of the reset spring respectively abut between the axial abutting portion 46 and the end of the rotating shaft limiting sleeve 5. By such arrangement, the reset mechanism 32 is a reset spring, with a simple structure and good use effect.

[0036] In an alternative embodiment, in addition to being set as a reset spring, the reset mechanism 32 can also be set as a tension spring, a spring piece, or a compression spring. When set as a tension spring, a spring piece, or a compression spring, its elastic reset direction is the same as that of the reset spring, but the specific setting manner of the tension spring, the spring piece, and the compression spring is not limited.

[0037] In an alternative embodiment, the reset structure can be a manually controlled reset mode.

[0038] See Figures 5 to 9 , in one embodiment, one circumferential end of the second limiting activity groove 52 is communicated with one axial side of the first limiting activity groove 51 to form the clearance area 53, and the second limiting activity groove 52 is located between the pressing structure and the first limiting activity groove 51 in the axial direction. By such arrangement, the limiting protrusion can be better limited to move in the first limiting activity groove 51, and when the limiting protrusion moves to the clearance area 53 in the second limiting activity groove 52, it can automatically reset to the first limiting activity groove 51, and the operation mode of the cover body 1 is simple and convenient.

The clamping portion 54 is provided with a clamping hole 541. A clamping structure 33 is provided at the end of the pressing cover 31. The clamping structure 33 cooperates with the clamping hole 541 to assemble and connect the pressing cover 31 and the rotating shaft limiting sleeve 5. With this arrangement, the installation method of the pressing cover 31 is simple, which is convenient for product production and assembly. In other embodiments, the pressing structure can directly form the end of the shaft limiting sleeve 5.

[0040] See Figures 1 to 11 , in one embodiment, a second adapter seat 21 is provided at the rear side of the body 2. A second adapter hole 22 is provided inside the second adapter seat 21. The rotating shaft limiting sleeve 5 is non-rotatably installed in the second adapter hole 22. For example, on the surfaces of the rotating shaft limiting sleeve 5 and the second adapter hole 22 that are nested with each other, there are guiding ribs and grooves with concave-convex fit, which can not only position circumferentially but also slide axially. The clamping portion 54 extends out of the second adapter hole 22 and is connected to the pressing cover 31. With this arrangement, the assembly connection between the rotating shaft limiting sleeve 5 and the pressing cover 31 is ingenious, which is convenient for the user to control the moving position of the rotating shaft limiting sleeve 5 by pressing the pressing cover 31 at the side. In other embodiments, the installation positions of the mutually cooperating rotating shaft limiting sleeve 5 and the rotating shaft assembly 4 can be equivalently interchanged.

[0041] See Figures 5 to 9 , in one embodiment, the height of the second limiting groove 52 in the axial direction is greater than the height of the rotating convex portion 41, but less than twice the height of the rotating convex portion 41. With this arrangement, it is better to avoid the phenomenon of the rotating convex portion 41 getting stuck in the second limiting groove 52, ensuring that the rotating convex portion 41 rotates smoothly and ensuring the pressing feel of the pressing cover 31.

Another rotating shaft limiting sleeve is non-rotatably installed in the second adapter hole 22. The above non-rotatable connection methods include but are not limited to the card slot fixing method and the screw connection method. With this arrangement, the assembly methods of the rotating shaft limiting sleeve 5 and the rotating shaft assembly 4 are simple and convenient for assembly.

[0043] See Figures 1 to 3, in one embodiment, the first open position is a vertical open position where the cover 1 is opened relative to the body 2 by [70°, 120], and the second open position is a horizontal open position where the cover 1 is opened relative to the body 2 by [150° 210°]; the central angle corresponding to the first limiting slot 51 is greater than or equal to 90°, and the central angle corresponding to the second limiting slot 52 is greater than or equal to 90°; with such a setting, the cover 1 can be maintained in the vertical open position and the horizontal open position, facilitating the user to use according to the actual situation.
