Description

Technical Field

[0001] This utility model belongs to the field of kitchen appliance technology, specifically relating to a pot lid assembly and a pressure cooking appliance. Background Technology

[0002] Some cooking appliances with pressure cooking functions (such as pressure cookers, micro-pressure rice cookers, etc.) have lids that are locked to the pot body. The lid can be opened by using the lid opening button to drive the lid opening component.

[0003] However, in certain special scenarios, it is necessary to restrict users' opening of the lid. For example, during pressure cooking, when the pot is in a high-pressure environment, opening the lid rashly will not only disrupt the high-pressure environment inside the pot and affect the normal progress of pressure cooking, but also pose safety issues.

[0004] Simply restricting the movement of the lid-opening button, preventing it from being pressed in certain situations, may limit the lid from opening, but users may sometimes misoperate. Even when the lid-opening button cannot be pressed, users may still apply excessive pressure to it. In this case, a large force is generated between the lid-opening button, the lid-opening component, and the limiting mechanism, which may cause the lid-opening component to break or be damaged. This not only damages the product and affects the normal opening of the cooking appliance, but also greatly reduces the safety of the product due to the forced opening operation.

[0053] Preferably, as Figure 1 、 Figure 2 The cover 1 is further provided with the float valve 11, and the float valve 11 has the upper floating position and the falling position, in the falling position, the button assembly is in the unlocking state, and the float valve 11 and the locking piece 6 avoid each other, and the locking piece 6 can normally move, in the upper floating position, the float valve 11 and the locking piece 6 stop to make the button assembly be in the protection state.

[0054] The movement of the locking piece 6 is limited by the stop of the float valve 11 and the locking piece 6, and the movement of the protection piece 3 is further limited by the stop of the locking piece 6 and the protection piece 3, so that the movement limiting of each component is more reliable and effective, and the service life does not substantially reduce after long time use, to be able to stably and reliably limit the movement of the locking piece 6 when the pressure in the pot is high to ensure that the pot cover cannot be opened, and when the pressure in the pot is not high, ensure that the button 2 can effectively drive the locking piece 6 to move to realize the opening of the pot cover.

[0055] When the float valve 11 is in the falling position, the gas pressure in the pot is balanced with the outside atmosphere, at this time the float valve 11 forms an avoidance to the locking piece 6, when the user presses the uncovering button 2, the force applied on the uncovering button 2 is transmitted to the protection piece 3 through the elastic piece 4, the protection piece 3 is driven to move under the thrust of the elastic piece 4, and the locking piece 6 is driven to move so as to be unlocked with the pot body, at this time the pot cover assembly can be turned and opened.

[0056] It should be noted that the utility model does not limit the stopping mode of the float valve 11 to the locking piece 6, which can be direct stopping, that is, the float valve 11 directly contacts the locking piece 6 to limit the movement of the locking piece 6.

[0057] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 4 The cover body 1 is further provided with a linkage 7, the locking piece 6 can drive the linkage 7 to move when rotating, and the float valve 11 is in the floating position and is in stop cooperation with the linkage 7.

[0058] The float valve 11 can be in stop cooperation with the linkage 7, thereby indirectly limiting the locking piece 6, so that the arrangement positions of the float valve 11 and the locking piece 6 are more flexible, thereby more reasonably utilizing the internal space of the pot cover assembly, improving the space utilization and saving the space.

[0059] It should be noted that the utility model does not limit the setting position of the uncovering button 2, in an embodiment, the uncovering button 2 is arranged on the top surface of the cover body 1, and the user can operate the uncovering button 2 by pressing downward.

[0060] In another preferred embodiment, as shown in Figure 1 、 Figure 2 The uncovering button 2 is arranged on the side of the cover body 1, the locking piece 6 is rotatably connected to the cover body 1, and the uncovering button 2 can move in the horizontal direction to drive the protection piece 3 to move horizontally to push the locking piece 6 to rotate.

[0061] Further, as shown in Figure 1 The uncovering button 2 and the protection piece 3 can move in the radial direction of the pot cover, and the movement directions of the two are the same.

[0062] The movement paths of the opening button 2 and the guard 3 are both horizontal, which makes the movement paths of the two same, further simplifies the user operation, and facilitates the opening button 2 to drive the guard 3, and facilitates the arrangement of the elastic member 4, so that the elastic member 4 applies reliable elastic force to the opening button 2 and the guard 3. On the other hand, it can also effectively save the size in the height direction of the pot cover, which helps to realize the light and thin design of the pot cover.

[0063] Specifically, as shown in Figure 3 , the horizontal movement of the guard 3 pushes the locking member 6, so that the locking member 6 rotates, so that the locking member 6 is unlocked by the hook and the pot body, and the pot cover assembly and the pot body are unlocked. At this time, the pot cover assembly can be turned up to open the cover.

[0064] Specifically, as shown in Figure 3 , the locking member 6 is vertically fixed to the cover body 1, the upper end is used to cooperate with the guard 3, the lower end is provided with a hook, and the two ends are rotatably connected to the pot cover through a rotating shaft. When the user presses the opening button 2, the guard 3 pushes the top end of the locking member 6 transversely inward, so that the lower end of the locking member 6 swings outward and is unlocked from the pot body.

[0065] Preferably, as shown in Figure 1 , Figure 3 , Figure 5 , the pot cover assembly further comprises a button seat 5 arranged on the cover body 1, the button seat 5 has a sliding channel 51 extending in the horizontal direction inside, the opening button 2 is arranged in the sliding channel 51, and the guard 3 has a trigger portion 31 penetrating out of the sliding channel 51 and cooperating with the locking member 6.

[0066] The opening button 2 is in the sliding channel 51 of the button seat 5 and can reciprocate along the extension direction of the sliding channel 51, and the sliding channel 51 extends in the radial direction of the pot cover, so that the movement path of the opening button 2 is limited in the radial direction of the pot cover, and the movement of the opening button 2 is more reliable and smooth, and the probability of jamming of the opening button 2 is reduced. The guard 3 is partially arranged in the sliding channel 51, which facilitates the arrangement of the elastic member 4 and reduces the installation difficulty, and is partially arranged outside the button seat 5, which is used to cooperate with the locking member 6 to facilitate the driving of the locking member 6.

[0067] As shown in Figure 3 , the side of the button seat 5 away from the center of the cover body 1 has a mounting hole for mounting the opening button 2, and the side toward the center of the cover body 1 has an opening 52 for the trigger portion 31 to extend out of.

[0068] Further, as shown in Figure 3 , Figure 5 , the button seat 5 is provided with an opening 52 for the trigger portion 31 to extend out of, and the opening 52 is provided with a guide protrusion 53 extending in the horizontal direction.

[0069] The guide protrusion 53 can guide the movement of the trigger part 31, so that the trigger part 31 can only reciprocate along the radial direction of the pot cover, thereby further improving the movement reliability of the protection part 3.

[0070] As shown in the drawings, the guide protrusion 53 can extend towards the inside of the sliding channel 51, or extend towards the outside of the sliding channel 51, and can completely surround the opening 52 or only surround part of the opening 52, as long as it can guide the horizontal movement of the trigger part 31. Figure 3 As shown in the drawings, the guide protrusion 53 can extend towards the inside of the sliding channel 51, or extend towards the outside of the sliding channel 51, and can completely surround the opening 52 or only surround part of the opening 52, as long as it can guide the horizontal movement of the trigger part 31.

[0071] Figure 3 As shown in the drawings, the cover opening button 2 has a stop protrusion 21 extending towards the inside of the sliding channel 51 and along the length direction of the sliding channel 51, and the gap L1 between the stop protrusion 21 and the end face of the sliding channel 51 in the initial position of the cover opening button 2 constitutes the maximum movement amount of the cover opening button 2. Figure 5 The gap L1 between the stop protrusion 21 and the end face of the sliding channel 51 in the initial position of the cover opening button 2 constitutes the maximum movement amount of the cover opening button 2, as shown in the drawings, when the cover opening button 2 moves inwardly to the position where the stop protrusion 21 contacts the end face of the sliding channel 51, the stop protrusion 21 and the end face of the sliding channel 51 stop each other, so that the cover opening button 2 cannot move any more, and thus the maximum movement amount. The maximum movement amount is not greater than the maximum compression amount of the elastic part 4, so that the elastic part 4 always remains in a reliable deformation range during the movement of the cover opening button 2, that is, when the cover opening button 2 reaches the maximum movement amount, the elastic part 4 has not reached the maximum compression amount. Thus, the force applied by the user on the cover opening button 2 can be effectively relieved, which can not only avoid that the elastic part 4 is excessively pressed to affect the service life, but also avoid that when the elastic part 4 reaches the maximum compression amount, the force transmitted by the cover opening button 2 to the protection part 3 through the elastic part 4 is large, thereby further reducing the risk of damage of the protection part 3, the locking part 6 and the float valve 11.

[0072] Figure 5 Specifically, as shown in the drawings, when the user presses the cover opening button 2, the cover opening button 2 can move inwardly along the radial direction of the cover body 1, the stop protrusion 21 protrudes inwardly along the radial direction of the pot cover, and the gap between the end of the stop protrusion 21 and the vertical end face of the sliding channel 51 close to the center of the cover body 1 constitutes the maximum movement amount of the cover opening button 2.

[0073] As a preferred embodiment of the utility model, as shown in the drawings, Figure 3 Figure 5 Specifically, as shown in the drawings, when the user presses the cover opening button 2, the cover opening button 2 can move inwardly along the radial direction of the cover body 1, the stop protrusion 21 protrudes inwardly along the radial direction of the pot cover, and the gap between the end of the stop protrusion 21 and the vertical end face of the sliding channel 51 close to the center of the cover body 1 constitutes the maximum movement amount of the cover opening button 2.

[0074] As a preferred embodiment of the utility model, as shown in the drawings, Figure 3 Figure 5 ​​​​As shown, the interior of the shield 3 has a limiting channel 32, and at least a partial region of the elastic member 4 is located in the limiting channel 32.

[0075] The elastic member 4 is located in the limiting channel 32, so that the shield 3 can also limit the elastic member 4, and the elastic member 4 can only deform in the axial direction, avoiding deflection and ensuring that the application direction of the elastic force is stable and reliable.

[0076] Specifically, as shown in the drawings, Figure 3 The axis of the elastic member 4 is horizontally arranged, one end of the elastic member 4 abuts and cooperates with the cover opening button 2, and the other end of the elastic member 4 is located in the limiting channel 32 and abuts and cooperates with the shield 3.

[0077] In a preferred embodiment of the utility model, as shown in the drawings, Figure 6 The cover body 1 is also provided with a driving member 16 and a pressure relief valve 12, the cover body 1 is provided with a pressure relief port 13, the pressure relief valve 12 blocks the pressure relief port 13, and the driving member 16 can drive the pressure relief valve 12 to move to open the pressure relief port 13.

[0078] The pot cover is also provided with a partially exposed driving member 16, the driving member 16 can drive the push rod 81, thereby realizing the function of manual pressure relief. When the equipment is powered off during cooking, the user can operate the driving member 16 to drive the push rod 81 of the electromagnetic valve 8, and then the push rod 81 lifts the pressure relief valve 12, the pressure relief port 13 is conducted to exhaust and relieve pressure, thereby realizing the function integration of automatic pressure relief and manual pressure relief of the cooking utensil. Therefore, after power failure, the user can realize rapid exhaust and pressure relief by operating the driving member 16, thereby shortening the pressure relief time and helping the user to quickly and safely open the cover.

[0079] Further, as shown in the drawings, Figure 2 , Figure 6 The driving member 16 includes the electromagnetic valve 8, the electromagnetic valve 8 has the push rod 81, the push rod 81 has a driving end 811 for cooperating with the driving member 16 to be driven by the driving member 16, and an acting end 812 for lifting the pressure relief valve 12 to open the pressure relief port 13.

[0080] Both pressure relief modes are performed by the electromagnetic valve 8, that is, the electromagnetic valve 8 is controlled, thereby controlling the pressure relief valve 12 by using the same component, without the need to additionally set a driving mechanism for the pressure relief valve 12, simplifying the structure of the pot cover, saving the internal space of the pot cover and saving the cost.

[0081] Further, one end of the driving member 16 is exposed outside the opening button 2. The driving member 16 is located outside the opening button 2, realizing the position integration of the driving member 16 and the opening button 2. On the one hand, no additional position is needed in the cover 1 for arranging the driving member 16 or the manual exhaust structure, improving the simplicity of the appearance of the pot cover, and at the same time, making the operation of the user more simple and convenient. On the other hand, since the driving member 16 and the opening button 2 are in the same position, the opening button 2 cannot be pressed under the state of pressure in the pot, and the user can operate the driving member 16 alone to make it lift the pressure relief valve 12 to exhaust and depressurize. Moreover, after the automatic exhaust and depressurization is completed through program control after the normal pressure cooking is finished, when the user opens the cover, the opening button 2 and the driving member 16 can be pressed at the same time, so that the pressure relief valve 12 is lifted again when the pot cover is opened, which helps to exhaust the residual gas in the pot, ensures safe opening of the cover, and avoids the gas pressure in the pot from rising again under the action of residual heat in the pot.

[0082] In an embodiment, as shown in FIG. 8, the push rod 81 is horizontally arranged, and a transmission member 9 is arranged between the acting end 812 and the pressure relief valve 12. The transmission member 9 includes a force receiving end, a triggering end, and a connecting portion between the force receiving end and the triggering end. The connecting portion is rotationally connected to the cover 1, and the acting end 812 can horizontally push the force receiving end to make the transmission member 9 rotate around the connecting portion, so that the triggering end lifts the pressure relief valve 12 to open the pressure relief port 13. Figure 2

[0083] The push rod 81 of the electromagnetic valve 8 is horizontally arranged, which not only can save the internal space of the cover 1, but also is convenient for cooperation with the opening button 2 and the driving member 16. The transmission member 9 is arranged between the electromagnetic valve 8 and the pressure relief valve 12, and the connecting portion of the transmission member 9 is rotationally connected to the cover 1, so that the transmission member 9 is a lever structure. When the acting end 812 of the push rod 81 pushes the force receiving end of the transmission member 9, the force receiving end swings downward, so that the transmission member 9 rotates as a whole around the connecting portion, the triggering end lifts upward to lift the pressure relief valve 12, and the pressure relief port 13 is opened. The lever structure can make the push rod 81 more easily lift the pressure relief valve 12 through the transmission member 9 by adjusting the length of the force arm, and thus the user operation is more labor-saving.
