[0028] The existing pressure rice cooking utensil needs to ensure that the cooking cavity is kept sealed in the pressure state, and one form is to provide a movable clamp mechanism on the upper cover, when the upper cover covers the inner pot, the clamp mechanism clamps the inner pot to maintain the sealing of the cooking cavity.

[0029] Because the force of the clamp clamping the inner pot is relatively large, an electrically driven clamp mechanism is usually needed to lock or release the upper cover and the inner pot. For the electrically driven structure, after the power is off, the electrically driven part cannot operate to drive the clamp to switch the state. If the user manually switches the clamp state, there is the problem of inconvenient operation.

[0030] The present application provides an upper cover and a cooking utensil, which aims to manually drive the clamp mechanism to open the upper cover under the condition of power failure.

[0031] Please refer to Figures 1 to 4In an embodiment of the present application, the upper cover 10 is used for the cooking appliance 100 with pressure, the upper cover 10 comprises a cover plate 1, a caliper mechanism 2 and a push rod mechanism 5, the cover plate 1 and the inner pot 30 of the cooking appliance 100 enclose to form a cooking cavity; the caliper mechanism 2 is slidingly connected to the cover plate 1 and has a locking state of clamping the inner pot 30 and an opening state of being away from the inner pot 30; the push rod mechanism 5 is movably arranged in the upper cover 10, one end of the push rod mechanism 5 is exposed to the upper cover 10, and the other end of the push rod mechanism 5 is connected to the caliper mechanism 2, and the push rod mechanism 5 can push the caliper mechanism 2 to switch to the opening state.

[0032] In the embodiment, the upper cover 10 covers the opening of the inner pot 30 of the cooking appliance 100, and the cover plate 1 of the upper cover 10 and the inner pot 30 enclose to form a cooking cavity, which is used for cooking food such as rice, the caliper mechanism 2 comprises two oppositely arranged calipers, the inner pot 30 is clamped by the two calipers to lock the inner pot 30 and the upper cover 10 together, and then the food in the cooking cavity is heated, so that the pressure in the cooking cavity is increased. The upper cover 10 is also provided with a push rod mechanism 5, one end of the push rod mechanism 5 is exposed to the upper cover 10, so that the user can directly touch one end of the push rod mechanism 5, the push rod mechanism 5 is displaced, and then the caliper mechanism 2 is switched to the opening state, so that the upper cover 10 and the inner pot 30 can be separated, and then the food in the inner pot 30 is processed. The push rod mechanism 5 provides a way for the user to manually open the upper cover 10, preventing the upper cover 10 from being unable to open due to power failure and other unexpected situations. The user only needs to push the push rod structure 5 to switch the caliper mechanism 2 to the opening state, which is simple and convenient to operate.

[0033] The cover plate 1, the caliper mechanism 2 and the push rod mechanism 5 can all be made of metal materials, such as stainless steel materials and aluminum alloy materials, which are solid, durable and have strong corrosion resistance. The cover plate 1 and the caliper mechanism 2 are commonly used in the market, and the sliding connection between the cover plate 1 and the caliper mechanism 2 is also commonly used in the market, so further limitation is not made here.

[0034] The technical scheme of the present application adopts the push rod mechanism 5 which can be manually triggered by the user on the upper cover 10, drives and connects the caliper mechanism 2 to switch from the locking state of clamping the inner pot 30 to the opening state of being away from the inner pot 30, so that the user can manually open the upper cover 10 under the condition of power failure to process the food inside the cooking appliance 100.

[0035] In the embodiment of the present application, as shown in Figure 1As shown, the upper cover 10 further comprises a linkage mechanism 3 and a driving mechanism 4, the linkage mechanism 3 is slidingly connected to the cover plate 1, and the driving mechanism 4 is arranged in the upper cover 10 and is used to drive the linkage mechanism 3 to slide relative to the cover plate 1, so that the linkage mechanism 3 drives the clamp mechanism 2 to switch between the locking state and the opening state.

[0036] In the embodiment, the upper cover 10 further comprises a linkage mechanism 3 and a driving mechanism 4, the driving mechanism 4 is drivingly connected to the linkage mechanism 3, so that the linkage mechanism 3 can slide on the upper cover 10, the linkage mechanism 3 is drivingly connected to the clamp mechanism 2, and the sliding of the linkage mechanism 3 can drive the clamp mechanism 2 to switch between the locking state and the opening state, so as to lock or open the inner pot 30 by the upper cover 10. The linkage mechanism 3 can be a slider commonly used in the clamp type pressure cooking utensil 100 on the market, and the slider is provided with S-shaped sliding grooves on the opposite sides, so that the clamp mechanism 2 slides along the S-shaped sliding grooves, and then moves close to or away from each other, so as to switch the clamp mechanism 2 between the locking state and the opening state. The linkage mechanism 3 can be made of metal material, such as stainless steel material or aluminum alloy material, which is strong, durable and has strong corrosion resistance. The driving mechanism 4 can directly drive the linkage mechanism 3 to move linearly by using a linear motor 41, or drive the linkage mechanism 3 to move linearly by using a rotating motor 41 through the transmission of a gear and a rack 31.

[0037] In the embodiment of the utility model, as shown in the figure, Figure 3 The push rod mechanism 5 comprises a driving piece 51 and a driven piece 52, one end of the driving piece 51 is partially exposed on the upper cover 10, the driven piece 52 is arranged in the upper cover 10, the other end of the driving piece 51 abuts against the driven piece 52, and the driven piece 52 abuts against the linkage mechanism 3. The driving piece 51 drives the driven piece 52 to move, so as to push the linkage mechanism 3 and the clamp mechanism 2 to switch between the locking state and the opening state.

[0038] In the embodiment, the push rod mechanism 5 comprises two parts of the driving piece 51 and the driven piece 52, because the sliding stroke of the linkage mechanism 3 is long, the two parts of the driving piece 51 and the driven piece 52 are used as the push rod mechanism 5, which can make it more labor-saving and the pushing distance shorter, and also facilitates assembly and reduces the requirement for machining precision. One end of the driving piece 51 is partially exposed on the upper cover 10, the other end of the driving piece 51 abuts against the driven piece 52 arranged in the upper cover 10, the user pushes one end of the driving piece 51 partially exposed on the upper cover 10 to move the driven piece 52, and then pushes the linkage mechanism 3 to switch the clamp mechanism 2 to the opening state, so as to realize the opening of the upper cover 10.

[0039] Specifically, the driven piece 52 can be slidingly arranged on the upper cover 10, or can be rotatably arranged on the upper cover 10.

[0040] In the embodiment of the utility model, as shown in the figure, Figure 3As shown, the driven part 52 is rotationally connected with the cover plate 1, the driving part 51 abuts against the first position of the driven part 52, and the linkage mechanism 3 abuts against the second position of the driven part 52, and the first position is closer to the connection between the driven part 52 and the cover plate 1 than the second position. A user can drive the driving part 51 to rotate the driven part 52 relative to the upper cover 10 to push the linkage mechanism 3.

[0041] In the embodiment, the driven part 52 is rotationally connected with the cover plate 1, the driving part 51 pushes the driven part 52 to rotate relative to the cover plate 1 at the first position of the driven part 52, and the driven part 52 further pushes the linkage mechanism 3 at the second position of the driven part 52 to finally drive the calipers 2 to move away from each other to open the upper cover 10. The rotational connection between the driven part 52 and the cover plate 1 can shorten the pushing distance of the driving part 51 compared with the linear connection, and improve the user experience. The distance between the first position and the connection between the driven part 52 and the cover plate 1 is smaller than the distance between the second position and the connection between the driven part 52 and the cover plate 1, so that the user only needs to push the driving part 51 to move a small distance, and the second position of the driven part 52 will move a large distance forward, and then the linkage mechanism 3 will move a large distance forward, thereby driving the calipers 2 to move away from each other to open the upper cover 10.

[0042] In the embodiment of the utility model, as shown in Figure 3 One end of the driven part 52 is hingedly connected with the upper cover 10, and the other end of the driven part 52 abuts against the linkage mechanism 3, and the driving part 51 abuts against the middle position of the driven part 52.

[0043] In the embodiment, the other end of the driven part 52 abuts against the linkage mechanism 3, one end of the driven part 52 is rotationally connected with the upper cover 10, and the driving part 51 abuts against and pushes the middle position of the driven part 52, so that the user only needs to push the driving part 51 to move a small distance, and the other end of the driven part 52 will move a large distance forward, and then the linkage mechanism 3 will move a large distance forward, thereby driving the calipers 2 to move away from each other to open the upper cover 10.

[0044] In the embodiment of the utility model, as shown in Figure 3 The other end of the driven part 52 is formed with an arc-shaped groove 521, and the linkage mechanism 3 abuts against the groove of the arc-shaped groove 521.

[0045] In order to prevent the other end of the driven part 52 from being separated from the linkage mechanism 3, in the embodiment, the arc-shaped groove 521 is formed at the other end of the driven part 52, and the linkage mechanism 3 is slidably abutted in the arc-shaped groove 521, so that when the driven part 52 rotates relative to the upper cover 10, the linkage mechanism 3 is always slidably abutted in the arc-shaped groove 521, preventing the separation between the two, causing the problem of manual unlocking failure.

[0046] In the embodiment of the utility model, as shown inFigure 3 As shown in the drawings, the side wall of the upper cover 10 is inwardly recessed to form a groove 6, a through hole 61 is formed in the groove bottom of the groove 6, the other end of the driving member 51 is movably arranged in the through hole 61 and abuts against the driven member 52, and the one end of the driving member 51 is limited to the edge of the through hole 61, and the driving member 51 can reciprocate along the groove wall of the groove 6.

[0047] In the embodiment, the side wall of the upper cover 10 is inwardly recessed to form a groove 6, the driving member 51 is movably arranged in the through hole 61 formed in the groove 6 and abuts against the driven member 52, and the other end of the driving member 51 is limited to the edge of the through hole 61, so that the driving member 51 cannot be pushed into the upper cover 10, thereby avoiding the problem of manual unlocking failure. The driving member 51 can reciprocate along the groove wall of the groove 6, thereby guiding the movement direction of the driving member 51 and preventing the problem of manual unlocking failure caused by the deflection of the movement direction of the driving member 51.

[0048] Please refer to Figure 1 In the embodiment of the utility model, the upper cover 10 further comprises an elastic member 7, one end of the elastic member 7 abuts against the edge of the through hole 61, and the other end of the elastic member 7 abuts against the one end of the driving member 51, which is used to reset the driving member 51 in the direction away from the groove bottom of the groove 6, and after resetting, the one end of the driving member 51 is located in the groove opening of the groove 6 or flush with the groove opening of the groove 6.

[0049] In the embodiment, the elastic member 7 is arranged between the edge of the through hole 61 of the groove 6 and the one end of the driving member 51, and the elastic member 7 can be a spring or other elastic components, such as a spring plate, which is not limited here. When the driving member 51 is pushed into the interior of the upper cover 10 to unlock the upper cover 10, the elastic member 7 is shortened and deformed under the action of external force, and when the external force is lost, the elastic member 7 restores the deformation to push the driving member 51 to move in the direction away from the groove bottom of the groove 6 to restore the initial position. Even if the driving member 51 moves towards the exterior of the upper cover 10, the manual resetting step is reduced, and the operation is more convenient. After resetting, the one end of the driving member 51 is located in the groove opening of the groove 6 or flush with the groove opening of the groove 6, thereby preventing the user from accidentally touching the driving member 51 to cause the interruption of cooking or personal injury.
