Description

Technical Field

[0001] The utility model relates to the technical field of small household appliances, and in particular to a lid assembly and a cooking appliance having the same. Background Art

[0002] Cooking appliances are indispensable kitchen equipment in daily life. Cooking appliances are used to prepare and cook various foods. A cooking appliance includes a pot body and a lid assembly. The lid assembly is detachably provided on the pot body. The pot body is used to hold food. When the lid assembly is buckled on the pot body, the lid assembly can keep the heat and steam inside the pot body and promote the uniform cooking of the food by the cooking appliance.

[0003] In the related art, the lid assembly includes an outer lid and an inner lid. A transmission member is movably provided on the outer lid. The inner lid is rotatably provided on the outer lid about its axis. The transmission member is drivingly connected to the inner lid. The inner lid is detachably provided on the outer lid. The inner lid has a lid tooth that can be buckled with the pot tooth of the pot body.

[0004] However, after the inner lid of the lid assembly in the related art is disassembled, the transmission member will be misaligned under the misoperation of the user, so that the inner lid cannot be installed on the outer lid. Summary of the Utility Model

[0005] The main purpose of the present utility model is to provide a lid assembly and a cooking appliance having the same, so as to solve the problem that after the inner lid of the lid assembly in the related art is disassembled, the transmission member will be misaligned under the misoperation of the user, so that the inner lid cannot be installed on the outer lid.

[0006] To achieve the above object, according to one aspect of the present utility model, there is provided a lid assembly, including: an outer lid, on which a transmission member is movably provided, a driving hole is provided on the transmission member, and the transmission member has a first position and a second position; an inner lid, which is detachably and rotatably provided below the outer lid, a driving column is provided on the inner lid and passes through the driving hole, and when the transmission member moves, it can drive the inner lid to rotate through the driving column. When the transmission member is in the first position, the inner lid is in an unlocked state, and when the transmission member is in the second position, the inner lid is in a locked state; a limiting member, which is movably provided on the outer lid and has a limiting position for limiting the transmission member in the first position and a first avoiding position for avoiding the transmission member so that the transmission member can move. When the limiting member is in the limiting position, the driving column can pass through the driving hole so that the inner lid can be installed below the outer lid.

[0007] Applying the technical solution of the present utility model, the cover assembly includes an outer cover, an inner cover and a limiting member. When the inner cover is installed on the outer cover, the driving column passes through the driving hole, and the limiting member is switched to the first avoidance position. The transmission member is switched between the first position and the second position. The transmission member drives the driving column to rotate through the driving hole, and drives the inner cover to rotate relative to the outer cover. When the transmission member is in the second position, the inner cover is in the locked state, and the inner cover is buckled with the pot body of the cooking appliance. When the transmission member is in the first position, the inner cover is in the unlocked state, and the inner cover is separated from the pot body of the cooking appliance. The inner cover can be detached relative to the outer cover. After the inner cover is detached, the limiting member is switched to the limiting position to limit the transmission member in the first position, preventing the user from accidentally operating the transmission member and changing the position of the driving hole. Thus, when the inner cover is installed again, the driving column can pass through the driving hole smoothly, and the inner cover can be installed on the outer cover smoothly.

[0008] Further, the limiting member is movably passed through the outer cover. When the inner cover is installed below the outer cover, the inner cover is in a stop fit with the limiting member, so that the limiting transmission member moves from the limiting position to the first avoidance position and remains in the first avoidance position. When the inner cover is installed below the outer cover, without additional operation by the user, by using the stop fit between the inner cover and the limiting member, the transmission member can be moved from the limiting position to the first avoidance position, simplifying the user operation.

[0009] Furthermore, the cover body assembly also includes: a driving member, which is arranged on the outer cover, the driving member drives the transmission member to move relative to the outer cover, and the transmission member drives the inner cover to rotate between a locked state and an unlocked state; a pressure limiting assembly, including an exhaust pipe and a pressure limiting valve, the exhaust pipe is passed through the outer cover and the inner cover, and the pressure limiting valve can be floatingly arranged at the upper end of the exhaust pipe; wherein, the cover body assembly also includes a pushing member, the pushing member and the exhaust pipe are both arranged on the outer cover, the pushing member is movable relative to the outer cover, when the transmission member drives the inner cover to rotate to the unlocked state, the transmission member drives the pushing member to lift the pressure limiting valve, and when the transmission member drives the inner cover to rotate to the locked state, the pushing member releases the pressure limiting valve. In the process of buckling the cover assembly to the pot body, firstly, the driving member is used to drive the transmission member to switch the inner cover to the unlocked state, at which time the transmission member drives the push member to lift the pressure limiting valve, and then the cover assembly is placed on the pot body, so that the inside of the pot body can be connected to the outside through the exhaust pipe, and even if the temperature inside the pot body is high, the exhaust can be exhausted through the exhaust pipe to avoid excessive pressure inside the pot body, so that the inner cover and the pot body are buckled, and the driving member is used to drive the transmission member to switch the inner cover to the locked state, at which time the cover teeth and the pot teeth are buckled, and the push member releases the pressure limiting valve to pressure cook the food in the cooking utensil. When the cover assembly is placed on the pot body and the inner cover is in the locked state, as the internal pressure of the cooking utensil changes, the inner cover will float up and down relative to the outer cover. Since the exhaust pipe and the push member of this embodiment are both arranged on the outer cover, the lifting stroke required by the push member is avoided to change during the floating process of the inner cover, and the matching reliability of the push member and the pressure limiting valve is improved. Furthermore, the exhaust pipe and the push member are arranged on the outer cover, so that when the inner cover is disassembled and assembled relative to the outer cover, the matching relationship between the transmission member, the push member and the pressure limiting valve is avoided from being affected.

[0010] Furthermore, the push member includes a connecting rod and a push rod, the middle part of the connecting rod and the middle part of the push rod are both hinged to the outer cover, the transmission member is drivingly connected to the first end of the connecting rod, the second end of the connecting rod is drivingly connected to the first end of the push rod, and the second end of the push rod is drivingly connected to the pressure limiting valve. The above connecting rod and push rod are adopted to make the layout of the push member more flexible. Specifically, when the transmission member drives the inner cover to rotate to the unlocked state, the transmission member lifts the first end of the connecting rod, so that the second end of the connecting rod presses down the first end of the push rod, so that the second end of the push rod lifts the pressure limiting valve. When the transmission member drives the inner cover to rotate to the locked state, the transmission member presses down the first end of the connecting rod, so that the second end of the connecting rod tilts up and separates from the first end of the push rod. Under the gravity of the pressure limiting valve, the pressure limiting valve presses down the second end of the push rod.

[0011] Furthermore, the pressure-limiting assembly further includes a solenoid valve disposed on the outer cover, and the solenoid valve is drivingly connected to the first end of the ejector rod. When the cover assembly is covered on the pot body and the inner cover is in the locked state, the solenoid valve is drivingly connected to the first end of the ejector rod, so as to drive the second end of the ejector rod to lift the pressure-limiting valve to separate from the pressure-limiting valve. Thus, during and before and after the pressure cooking process of the cooking appliance, the solenoid valve, the ejector rod and the pressure-limiting valve cooperate to change the communication state between the exhaust pipe and the outside, thereby enriching the cooking methods of pressure cooking.

[0012] Furthermore, the first end of the connecting rod is located on the side of the hinge axis of the connecting rod and the outer cover close to the pressure-limiting valve, and the second end of the ejector rod is located on the side of the hinge axis of the ejector rod and the outer cover close to the pressure-limiting valve. With the connecting rod, the ejector rod and the pressure-limiting valve arranged in the above layout, the distance between the first end of the connecting rod and the second end of the ejector rod can be reduced, making the layout among the connecting rod, the ejector rod and the pressure-limiting valve more compact.

[0013] Furthermore, the outer cover includes a mounting hole for mounting the limiting member. The limiting member includes a rod portion inserted through the mounting hole and a block portion connected to the rod portion. When the block portion is in limit fit with the transmission member, the limiting member is in the limiting position. When the block portion is in avoidance fit with the transmission member, the limiting member is in the first avoidance position. With the limiting member having the above structure, the rod portion is inserted into the mounting hole, which is convenient for installing the limiting member and guides the movement of the limiting member relative to the inner lining, enabling the limiting member to move smoothly and reliably between the limiting position and the first avoidance position.

[0014] Furthermore, the cover assembly further includes an elastic member disposed between the outer cover and the limiting member. The elastic member applies an elastic force to the limiting member to keep the limiting member in the limiting position. When the inner cover is disassembled, the inner cover is separated from the limiting member, and the limiting member is acted on by the elastic force of the elastic member, so that the transmission member moves from the first avoidance position to the limiting position and remains in the limiting position. Thus, when the inner cover is not installed, the limiting member restricts the movement of the transmission member, so that the handle cannot be operated and the cover assembly cannot be closed, avoiding the operation of closing the cover when the inner cover is not installed.

[0015] Furthermore, the outer cover includes an inner lining disposed outside the inner cover and a face cover disposed outside the inner lining. The limiting member is movably disposed on the inner lining, and an arc-shaped hole for guiding and cooperating with the driving column is provided on the inner lining. The arc-shaped hole extends along the circumferential direction of the inner lining. During the process that the driving column drives the driving column to rotate through the driving hole, the driving column moves in the arc-shaped hole along the extending direction of the arc-shaped hole, and the arc-shaped hole is used to guide the rotation of the driving column.

[0016] Further, a chute is provided on the inner side wall of the outer cover, and a plug block slidably engaged with the chute is provided on the outer side wall of the inner cover. The dimension of the chute along the circumferential direction of the outer cover is larger than the dimension of the plug block along the circumferential direction of the outer cover, and the width of the chute is larger than the dimension of the plug block along the width direction of the chute. A cover tooth that engages with the pot tooth of the pot body of the cooking appliance is provided at the lower edge of the inner cover. When installing the inner cover, the inner cover is inclined relative to the outer cover to insert the plug block into the chute, and then the inner cover is pushed, so that with the plug block as the swing point, the inner cover swings towards the direction close to the outer cover, thereby installing the inner cover on the outer cover. When disassembling the inner cover, the inner cover is pulled, so that with the plug block as the swing point, the inner cover swings towards the direction away from the outer cover, and the inner cover is inclined relative to the outer cover to facilitate taking out the plug block from the chute; a guide groove is further provided on the inner side wall of the outer cover, and a clamping block that is guidingly engaged with the guide groove is provided on the outer side wall of the inner cover. When installing the inner cover, the inner cover is inclined relative to the outer cover to insert the plug block into the chute, and then the inner cover is pushed, so that with the plug block as the swing point, the inner cover swings towards the direction close to the outer cover, causing the clamping block to extend into the guide groove, thereby installing the inner cover on the outer cover. When disassembling the inner cover, the inner cover is pulled, so that with the plug block as the swing point, the inner cover swings towards the direction away from the outer cover, causing the clamping block to disengage from the guide groove, and the inner cover is inclined relative to the outer cover to facilitate taking out the plug block from the chute; the cover body assembly further includes a supporting member movably provided on the outer cover. The supporting member has a second avoiding position for avoiding the clamping block from entering the guide groove and a supporting position for supporting the clamping block to keep the clamping block in the guide groove. When the supporting member is in the second avoiding position, the inner cover can be removed from the outer cover. When the supporting member is in the supporting position, the inner cover is installed on the outer cover. When installing the inner cover, the inner cover is inclined relative to the outer cover to insert the plug block into the chute, and then the inner cover is pushed, so that with the plug block as the swing point, the inner cover swings towards the direction close to the outer cover, causing the clamping block to press the supporting member. The supporting member switches to the avoiding position, the clamping block extends into the guide groove, and the supporting member switches to the supporting position, thereby installing the inner cover on the outer cover. When disassembling the inner cover, the supporting member is switched to the avoiding position, the inner cover is pulled, so that with the plug block as the swing point, the inner cover swings towards the direction away from the outer cover, causing the clamping block to disengage from the guide groove, and the inner cover is inclined relative to the outer cover to facilitate taking out the plug block from the chute.

[0017] According to another aspect of the present utility model, a cooking appliance is provided, which includes a lid assembly. The lid assembly is the lid assembly provided above. When the inner lid is installed on the outer lid, the driving post passes through the driving hole, and the limiting member is switched to the first avoidance position. The operating handle is operated to switch the transmission member between the first position and the second position, and drive the inner lid to rotate relative to the outer lid. When the transmission member is in the second position, the inner lid is in the locked state, and the inner lid is fastened to the pot body of the cooking appliance. When the transmission member is in the first position, the inner lid is in the unlocked state, and the inner lid is separated from the pot body of the cooking appliance. The inner lid can be disassembled relative to the outer lid. After the inner lid is disassembled, the limiting member is switched to the limiting position to limit the transmission member in the first position, so as to prevent the user from misoperating the transmission member and changing the position of the driving hole. Thus, when the inner lid is installed again, the driving post can pass through the driving hole smoothly, and the inner lid can be installed on the outer lid smoothly.

DETAILED DESCRIPTION

[0060] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0061] like Figures 1 to 27As shown in the figure, an embodiment of the present utility model provides a cover assembly. The cover assembly includes an outer cover 10, a handle 20, an inner cover 30, and a limiting member 40. A transmission member 11 is movably arranged on the outer cover 10. A driving hole 113 is arranged on the transmission member 11. The transmission member 11 has a first position and a second position. The handle 20 is movably arranged on the outer cover 10 and can drive the transmission member 11 to move. The inner cover 30 is detachably and rotatably arranged below the outer cover 10. A driving column 31 penetrating through the driving hole 113 is arranged on the inner cover 30. When the transmission member 11 moves, it can drive the inner cover 30 to rotate through the driving column 31. When the transmission member 11 is in the first position, the inner cover 30 is in an unlocked state. When the transmission member 11 is in the second position, the inner cover 30 is in a locked state. The limiting member 40 is movably arranged on the outer cover 10 and has a limiting position for limiting the transmission member 11 in the first position and a first avoiding position for avoiding the transmission member 11 so that the transmission member 11 can move. When the limiting member 40 is in the limiting position, the driving column 31 can penetrate through the driving hole 113 so that the inner cover 30 can be installed below the outer cover 10.

[0062] When applying the cover assembly provided by this embodiment, the cover assembly includes an outer cover 10, a handle 20, an inner cover 30, and a limiting member 40. When the inner cover 30 is installed on the outer cover 10, the driving column 31 penetrates through the driving hole 113, and the limiting member 40 is switched to the first avoiding position. The handle 20 is operated to make the transmission member 11 switch between the first position and the second position. The transmission member 11 drives the driving column 31 to rotate through the driving hole 113 and drives the inner cover 30 to rotate relative to the outer cover 10. When the transmission member 11 is in the second position, the inner cover 30 is in a locked state, and the inner cover 30 is buckled with the pot body of the cooking appliance. When the transmission member 11 is in the first position, the inner cover 30 is in an unlocked state, and the inner cover 30 is separated from the pot body of the cooking appliance. The inner cover 30 can be detached relative to the outer cover 10. After the inner cover 30 is detached, the limiting member 40 is switched to the limiting position to limit the transmission member 11 in the first position, avoiding the user from misoperating the transmission member and changing the position of the driving hole 113. Thus, when the inner cover 30 is installed again, the driving column 31 can penetrate through the driving hole 113 smoothly, and the inner cover can be installed on the outer cover smoothly.

[0063] It should be noted that the cover assembly further includes a driving member for driving the transmission member 11 to move relative to the outer cover 10. The driving member includes a handle or a driving motor. When the driving member includes a handle, the transmission member 11 is driven to move by the handle 20. Since the limiting member 40 is switched to the limiting position, the transmission member 11 is limited to the first position to prevent the user from accidentally operating the handle 20 and changing the position of the driving hole 113. When the driving member includes a driving motor, the transmission member 11 is driven to move by the driving motor. A trigger switch is provided on the cooking appliance for turning on or off the driving motor. Since the limiting member 40 is switched to the limiting position to limit the transmission member 11 to the first position, the user is prevented from accidentally operating the trigger switch and changing the position of the transmission member 11, effectively preventing the trigger switch from being accidentally operated by the user.

[0064] As Figure 1 , Figure 2 , Figure 8 , Figure 12 , Figure 15a , Figure 15b , Figure 22 and Figure 26 shown, the limiting member 40 is movably inserted through the outer cover 10. When the inner cover 30 is installed below the outer cover 10, the inner cover 30 is in a stop fit with the limiting member 40, so that the transmission member 11 moves from the limiting position to the first avoidance position and remains in the first avoidance position. When the inner cover 30 is installed below the outer cover 10, without the need for additional user operation, by using the stop fit between the inner cover 30 and the limiting member 40, the transmission member 11 can be moved from the limiting position to the first avoidance position, simplifying the user operation.

[0065] As Figure 1 , Figure 2 , Figures 4 to 13 , Figure 15a , Figure 15b , Figures 19 to 27 shown, the outer cover 10 includes a mounting hole for mounting the limiting member 40. The limiting member 40 includes a rod portion 41 inserted through the mounting hole and a block portion 42 provided and connected to the rod portion 41. When the block portion 42 is in a limiting fit with the transmission member 11, the limiting member 40 is in the limiting position. When the block portion 42 is in an avoidance fit with the transmission member 11, the limiting member 40 is in the first avoidance position. With the limiting member 40 having the above structure, the rod portion 41 is inserted into the mounting hole, which facilitates the installation of the limiting member 40 and guides the movement of the limiting member 40 relative to the inner liner 13, enabling the limiting member 40 to move smoothly and reliably between the limiting position and the first avoidance position.

[0066] As Figure 12 , Figure 13 , Figure 23 and Figure 27As shown, the cover assembly further includes an elastic member 50 disposed between the outer cover 10 and the limiting member 40. The elastic member 50 applies an elastic force to the limiting member 40 to keep the limiting member 40 in the limiting position. When the inner cover 30 is disassembled, the inner cover 30 is separated from the limiting member 40. The limiting member 40 is acted upon by the elastic force of the elastic member 50, so that the transmission member 11 moves from the first avoidance position to the limiting position and remains in the limiting position. Thus, when the inner cover 30 is missing during assembly, the limiting member 40 restricts the movement of the transmission member 11, making the handle 20 inoperable and the cover assembly unable to be closed, avoiding the operation of closing the cover when the inner cover 30 is missing.

[0067] Specifically, at least two floating members are further disposed on the outer cover 10. The floating members can abut against the outer top wall of the inner cover 30, so that the inner cover 30 can float relative to the pot body in a direction approaching or away from the outer cover 10. Thus, when the cover assembly is placed on the pot body and during the process of the inner cover 30 rotating relative to the outer cover 10, the elastic expansion and contraction of the floating members can be utilized to prevent the inner cover 30 from tilting, thereby avoiding interference between the cover teeth and the pot teeth, making the opening and closing of the cover assembly smooth. During the cooking process, with the change of pressure inside the cooking appliance, the elastic expansion and contraction of the floating members are utilized to make the inner cover 30 float relative to the pot body in a direction approaching or away from the outer cover 10.

[0068] In this embodiment, the elastic member 50 includes a spring.

[0069] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 10 、 Figure 15a 、 Figure 15b 、 Figure 17 、 Figure 20 and Figure 24 As shown, the outer cover 10 includes a lining 13 disposed outside the inner cover 30 and a face cover 14 disposed outside the lining 13. The limiting member 40 is movably disposed on the lining 13. An arc-shaped hole 131 that is in guiding cooperation with the driving column 31 is disposed on the lining 13. The arc-shaped hole 131 extends along the circumferential direction of the lining 13. During the process of the transmission member 11 driving the driving column 31 to rotate through the driving hole 113, the driving column 31 moves in the arc-shaped hole 131 along the extending direction of the arc-shaped hole 131, and the arc-shaped hole 131 is utilized to guide the rotation of the driving column 31.

[0070] As Figure 4 、 Figure 6 、 Figure 10 、 Figure 17 、 Figure 20 and Figure 24As shown, the driving hole 113 is a strip-shaped hole. During the process that the transmission member 11 drives the driving column 31 to rotate through the driving hole 113, the driving column 31 moves within the arc-shaped hole 131 along the extending direction of the arc-shaped hole 131, and the driving column 31 also moves within the strip-shaped hole along the extending direction of the strip-shaped hole. Thus, during the movement of the transmission member 11, it is convenient to maintain the driving cooperation between the driving hole 113 and the driving column 31.

[0071] As Figure 1 , Figure 3 , Figure 15a and Figure 16 As shown, a sliding groove 17 is provided on the inner side wall of the outer cover 10, and a plug 33 that is slidably engaged with the sliding groove 17 is provided on the outer side wall of the inner cover 30. The dimension of the sliding groove 17 along the circumferential direction of the outer cover 10 is larger than the dimension of the plug 33 along the circumferential direction of the outer cover 10, and the width of the sliding groove 17 is larger than the dimension of the plug 33 along the width direction of the sliding groove 17. A cover tooth that is buckled with the pot tooth of the pot body of the cooking appliance is provided at the lower edge of the inner cover 30. When installing the inner cover 30, the inner cover 30 is inclined relative to the outer cover 10 to insert the plug 33 into the sliding groove 17, and then the inner cover 30 is pushed. Thus, with the plug 33 as the swing point, the inner cover 30 swings towards the direction close to the outer cover 10, so as to install the inner cover 30 on the outer cover 10. When disassembling the inner cover 30, the inner cover 30 is pulled. Thus, with the plug 33 as the swing point, the inner cover 30 swings towards the direction away from the outer cover 10, and the inner cover 30 is inclined relative to the outer cover 10 to facilitate taking out the plug 33 from the sliding groove 17.

[0072] Wherein, when the inner cover 30 is installed on the outer cover 10, the cover body assembly is covered on the pot body. Since the dimension of the sliding groove 17 along the circumferential direction of the outer cover 10 is larger than the dimension of the plug 33 along the circumferential direction of the outer cover 10, the inner cover 30 can be rotated relative to the outer cover 10, and the plug 33 slides within the sliding groove 17 along the rotation direction, so that the cover tooth and the pot tooth of the pot body are buckled or separated. During the cooking process, since the width of the sliding groove 17 is larger than the dimension of the plug 33 along the width direction of the sliding groove 17, with the change of the pressure inside the cooking appliance, the inner cover 30 floats towards the direction close to or away from the outer cover 10 relative to the pot body, and the plug 33 slides within the sliding groove 17 along the floating direction.

[0073] As Figure 1 , Figure 2 , Figure 15a and Figure 15bAs shown, a guide groove 15 is further provided on the inner side wall of the outer cover 10, and a clamping block 32 that is in guiding cooperation with the guide groove 15 is provided on the outer side wall of the inner cover 30. When installing the inner cover 30, the inner cover 30 is inclined relative to the outer cover 10 so that the insertion block 33 is inserted into the sliding groove 17, and then the inner cover 30 is pushed. Thus, with the insertion block 33 as the swing point, the inner cover 30 swings towards the direction close to the outer cover 10, so that the clamping block 32 extends into the guide groove 15, thereby installing the inner cover 30 onto the outer cover 10. When disassembling the inner cover 30, the inner cover 30 is pulled, so that with the insertion block 33 as the swing point, the inner cover 30 swings towards the direction away from the outer cover 10, so that the clamping block 32 disengages from the guide groove 15, and the inner cover 30 is inclined relative to the outer cover 10 to facilitate taking out the insertion block 33 from the sliding groove 17.

[0074] In this embodiment, the dimension of the guide groove 15 along the circumferential direction of the outer cover 10 is larger than the dimension of the clamping block 32 along the circumferential direction of the outer cover 10. When the inner cover 30 is inclined relative to the outer cover 10, the clamping block 32 slides in the guide groove 15 along the rotation direction. The width of the guide groove 15 is larger than the dimension of the clamping block 32 along the width direction of the guide groove 15. During the floating process of the inner cover 30, the clamping block 32 slides in the guide groove 15 along the floating direction.

[0075] As Figure 2 and Figure 15b shown, the cover assembly further includes a supporting member 60 movably provided on the outer cover 10. The supporting member 60 has a second avoidance position for avoiding the clamping block 32 from entering the guide groove 15 and a supporting position for supporting the clamping block 32 to keep the clamping block 32 in the guide groove 15. When the supporting member 60 is in the second avoidance position, the inner cover 30 can be detached from the outer cover 10. When the supporting member 60 is in the supporting position, the inner cover 30 is installed on the outer cover 10. When installing the inner cover 30, the inner cover 30 is inclined relative to the outer cover 10 so that the insertion block 33 is inserted into the sliding groove 17, and then the inner cover 30 is pushed. Thus, with the insertion block 33 as the swing point, the inner cover 30 swings towards the direction close to the outer cover 10, so that the clamping block 32 presses the supporting member 60, and the supporting member 60 switches to the avoidance position. The clamping block 32 extends into the guide groove 15, and the supporting member 60 switches to the supporting position, thereby installing the inner cover 30 onto the outer cover 10. When disassembling the inner cover 30, the supporting member 60 is switched to the avoidance position, and the inner cover 30 is pulled. Thus, with the insertion block 33 as the swing point, the inner cover 30 swings towards the direction away from the outer cover 10, so that the clamping block 32 disengages from the guide groove 15, and the inner cover 30 is inclined relative to the outer cover 10 to facilitate taking out the insertion block 33 from the sliding groove 17.

[0076] In this embodiment, a notch communicating with the guide groove 15 is provided on the outer cover 10, the supporting member 60 is arranged in the notch, and the clamping block 32 can enter and exit the guide groove 15 through the notch.

[0077] In the related art, a pivot is provided at the center of the outer cover, and the inner cover is connected to the pivot by means of a nut, so that the pivot and the inner cover are movably connected.

[0078] like Figure 1 , Figure 2 , Figure 12 , Figure 15a , Figure 15b as well as Figure 22 As shown, in this embodiment, the outer cover 10 is provided with an exhaust pipe 16, and the inner cover 30 is provided with an avoidance hole for the exhaust pipe 16 to pass through. In this way, the avoidance hole only avoids the exhaust pipe 16. Since the outer cover 10 is not provided with a pivot in the related art, the avoidance hole does not need to be provided as a pivot hole that cooperates with the pivot, thereby reducing the number of components and reducing the cost. In addition, the exhaust pipe 16 provided on the outer cover 10 will not interfere with the pivot in the related art, and the original setting position of the exhaust pipe 16 does not need to be adjusted on the outer cover 10, thereby ensuring the original layout design on the outer cover 10, that is, the cover assembly of the present application can retain the exhaust pipe 16 in the original position under the premise of only minimal modification. In this way, during the mold processing of the outer cover 10 and the inner cover 30, there is no need to make major adjustments to the mold, thereby reducing the design cost and improving the processing efficiency.

[0079] Among them, Figures 1 to 13 As shown, the exhaust pipe is arranged concentrically with respect to the inner cover, that is, the exhaust pipe is arranged coaxially with the rotation axis of the inner cover. Figures 13 to 27 As shown, the exhaust pipe is eccentrically arranged relative to the inner cover, that is, the exhaust pipe is arranged parallel to the rotation axis of the inner cover.

[0080] like Figures 1 to 13 As shown, in an embodiment where the exhaust pipe is arranged concentrically with respect to the inner cover, the outer cover 10 includes an inner lining 13 arranged outside the inner cover 30 and a surface cover 14 arranged outside the inner lining 13, the transmission member 11 is movably arranged on the inner lining 13, the handle 20 includes a first gripping portion 211 and a driving portion 212 connected to the first gripping portion 211, the first gripping portion 211 is rotatably arranged on the surface cover 14, a first avoidance hole for avoiding the driving portion 212 is arranged on the surface cover 14, and the driving portion 212 can drive the transmission member 11 to move. By utilizing the structure that the surface cover 14 can cover the inner lining 13 and the outer surface of the inner lining 13, the user operates the first gripping portion 211 arranged on the surface cover 14 to drive the transmission member 11 arranged on the inner lining 13 to switch between the first position and the second position through the driving portion 212 penetrating the first avoidance hole.

[0081] like Figure 4 as well as Figures 6 to 13As shown, the transmission member 11 includes a sliding plate 111, and a swing rod 112 is swingably arranged along a direction parallel to the bottom surface of the outer cover 10. The user operates the first holding portion 211 provided on the face cover 14, and drives the sliding plate 111 to move horizontally through the driving portion 212 passing through the first avoidance hole, so that the transmission member 11 switches between a first position and a second position. When the limiting member 40 is in the limiting position, the limiting member 40 can be in limiting cooperation with the sliding plate 111 in the moving direction of the sliding plate 111.

[0082] It should be noted that when the cover assembly is covered on the pot body of the cooking appliance, the bottom surface of the outer cover 10 is arranged parallel to the horizontal plane, and when the cover assembly is opened from the pot body, the bottom surface of the outer cover 10 is arranged obliquely to the horizontal plane.

[0083] As Figure 4 、 Figure 6 and Figure 10 As shown, a sliding cavity 132 for the sliding plate 111 to move horizontally is provided on the outer wall of the inner liner 13. The sliding cavity 132 has a first limiting wall 1321 and a second limiting wall 1322 oppositely arranged along the moving direction of the sliding plate 111. When the sliding plate 111 is in limiting cooperation with the first limiting wall 1321, the transmission member 11 is in the first position, and when the sliding plate 111 is in limiting cooperation with the second limiting wall 1322, the transmission member 11 is in the second position.

[0084] As Figure 4 、 Figure 6 and Figure 10 As shown, a handle seat 141 is provided on the face cover 14. The first holding portion 211 is rotatably arranged on the handle seat 141. The sliding plate 111 includes a plate body 1111 and a support seat 1112 provided on the plate body 1111. A U-shaped driving groove 1113 extending along the up and down direction of the outer cover 10 is provided on the support seat 1112. The driving portion 212 includes a driving shaft 2121 passing through the U-shaped driving groove 1113. By flipping the first holding portion 211, the driving portion 212 is driven to swing relative to the handle seat 141. The driving shaft 2121 moves in the U-shaped driving groove 1113 along the up and down direction of the outer cover 10, and drives the sliding plate 111 to move horizontally relative to the inner liner 13.

[0085] As Figure 9 and Figure 13As shown, when the limiting member 40 is in the limiting position, the distance between the lower end of the rod portion 41 and the lower surface of the inner lining is H1, the lower surface of the block portion 42 is lower than the upper surface of the plate body 1111, and the height difference between the lower surface of the block portion 42 and the upper surface of the plate body 1111 is H2. When the limiting member 40 is in the first avoidance position, the distance between the lower end of the rod portion 41 and the lower surface of the inner lining is H3, and H1 - H3 > H2. The above dimensional relationship effectively ensures that when the limiting member 40 is in the first avoidance position, the horizontal movement of the sliding plate 111 relative to the inner lining 13 will not interfere with the block portion 42.

[0086] As Figures 14a to 14f shown, the cover assembly further includes: a driving member and a pressure limiting assembly 43. The driving member is arranged on the outer cover 10, and the driving member drives the transmission member 11 to move relative to the outer cover 10, and the transmission member 11 drives the inner cover 30 to rotate between a locked state and an unlocked state. The pressure limiting assembly 43 includes an exhaust pipe 16 and a pressure limiting valve 44. The exhaust pipe 16 passes through the outer cover 10 and the inner cover 30, and the pressure limiting valve 44 is movably arranged at the upper end of the exhaust pipe 16. Among them, the cover assembly further includes a pushing member 18. Both the pushing member 18 and the exhaust pipe 16 are arranged on the outer cover 10, and the pushing member 18 is movable relative to the outer cover 10. When the transmission member 11 drives the inner cover 30 to rotate to the unlocked state, the transmission member 11 drives the pushing member 18 to lift the pressure limiting valve 44. When the transmission member 11 drives the inner cover 30 to rotate to the locked state, the pushing member 18 releases the pressure limiting valve 44.

[0087] During the process of buckling the cover assembly onto the pot body, first use the driving member to drive the transmission member 11 to switch the inner cover 30 to the unlocked state. At this time, the transmission member 11 drives the pushing member 18 to lift the pressure limiting valve 44, and then cover the cover assembly on the pot body, so that the inside of the pot body can communicate with the outside through the exhaust pipe 16. Even if the temperature inside the pot body is relatively high, it can be exhausted through the exhaust pipe 16, avoiding excessive air pressure inside the pot body and facilitating the buckling of the inner cover and the pot body. Use the driving member to drive the transmission member 11 to switch the inner cover 30 to the locked state. At this time, the cover teeth and the pot teeth are buckled together, and the pushing member 18 releases the pressure limiting valve 44 to perform pressure cooking on the food in the cooking appliance. And, during the process of opening the cover of the cooking appliance, first use the driving member to drive the transmission member 11 to switch the inner cover 30 to the unlocked state, separate the cover teeth and the pot teeth, and the pushing member 18 lifts the pressure limiting valve 44, so that the high-pressure gas inside the pot body can be discharged through the exhaust pipe 16, reducing the air pressure inside the pot body to reduce the pressure difference between the inside and outside of the cooking appliance and improving the operating safety during the process of opening the cover.

[0088] In addition, when the cover assembly is covered on the pot body and the inner cover 30 is in a locked state, the inner cover 30 will float up and down relative to the outer cover 10 as the internal pressure of the cooking utensil changes. Since the exhaust pipe 16 and the push piece 18 of this embodiment are both arranged on the outer cover 10, the change of the lifting stroke required by the push piece 18 is avoided during the floating process of the inner cover 30, thereby improving the matching reliability of the push piece 18 and the pressure limiting valve 44. In addition, the exhaust pipe 16 and the push piece 18 are arranged on the outer cover 10, so as to avoid affecting the matching relationship between the transmission member 11, the push piece 18 and the pressure limiting valve 44 when the inner cover 30 is disassembled relative to the outer cover 10.

[0089] like Figures 14a to 14f As shown, the push member 18 includes a connecting rod 181 and a push rod 182, the middle parts of the connecting rod 181 and the middle parts of the push rod 182 are hinged to the outer cover 10, the transmission member 11 is drivingly connected to the first end of the connecting rod 181, the second end of the connecting rod 181 is drivingly connected to the first end of the push rod 182, and the second end of the push rod 182 is drivingly connected to the pressure limiting valve 44. The above-mentioned connecting rod 181 and push rod 182 are adopted to make the layout of the pushing member 18 more flexible. Specifically, when the transmission member 11 drives the inner cover 30 to rotate to the unlocked state, the transmission member 11 lifts the first end of the connecting rod 181, so that the second end of the connecting rod 181 presses down the first end of the push rod 182, so that the second end of the push rod 182 lifts the pressure limiting valve 44. When the transmission member 11 drives the inner cover 30 to rotate to the locked state, the transmission member 11 presses down the first end of the connecting rod 181, so that the second end of the connecting rod 181 is lifted and separated from the first end of the push rod 182. Under the action of gravity of the pressure limiting valve 44, the pressure limiting valve 44 presses down the second end of the push rod 182.

[0090] It should be noted that the middle part of the connecting rod 181 refers to the part of the connecting rod 181 except its two ends, and the middle part of the top rod 182 refers to the part of the top rod 182 except its two ends. The middle parts of the connecting rod 181 and the top rod 182 are hinged to the outer cover 10 to facilitate the lever pushing effect.

[0091] In this embodiment, the pressure limiting assembly 43 further includes a solenoid valve, which is disposed on the outer cover 10 and is drivingly connected to the first end of the push rod 182. When the cover assembly is covered on the pot body and the inner cover 30 is in a locked state, the solenoid valve is drivingly connected to the first end of the push rod 182, so that the second end of the push rod 182 is driven by the solenoid valve to lift the pressure limiting valve 44 and separate the pressure limiting valve 44, so that during and before and after the pressure cooking of the cooking appliance, the solenoid valve, the push rod 182 and the pressure limiting valve 44 cooperate to change the connection state between the exhaust pipe 16 and the outside world, thereby enriching the cooking method of pressure cooking.

[0092] like Figures 14a to 14fAs shown, the middle part of the pushing member 18 has a second hinge shaft 1812, and the middle part of the push rod 182 has a first hinge shaft 1823. Both the first hinge shaft 1823 and the second hinge shaft 1812 are perpendicular to the up-and-down direction of the cover assembly. The pushing member 18 is hinged to the outer cover 10 through the first hinge shaft 1823, and the push rod 182 is hinged to the outer cover 10 through the second hinge shaft 1812.

[0093] As Figures 14a to 14f shown, the transmission member 11 has a pushing block 114 and a transmission inclined surface 115 arranged at intervals in its moving direction. The transmission inclined surface 115 extends in the direction away from the connecting rod 181 in the up-and-down direction. Among them, when the transmission member 11 drives the inner cover 30 to rotate to the unlocked state, the transmission member 11 jacks up the first end of the connecting rod 181 through the pushing block 114. When the transmission member 11 drives the inner cover 30 to rotate to the locked state, the transmission member 11 presses down the first end of the connecting rod 181 through the transmission inclined surface 115. When the transmission member 11 drives the inner cover 30 to rotate to the unlocked state, move the transmission member 11 in the direction from the pushing block 114 to the transmission inclined surface 115. The pushing block 114 moves below the connecting rod 181 to the lower part of the first end of the connecting rod 181, and the pushing block 114 jacks up the first end of the connecting rod 181. When the transmission member 11 drives the inner cover 30 to rotate to the locked state, move the transmission member 11 in the direction from the transmission inclined surface 115 to the pushing block 114. The pushing block 114 moves below the connecting rod 181 to leave the first end of the connecting rod 181. At this time, the transmission inclined surface 115 moves to the first end of the connecting rod 181, and the transmission inclined surface 115 contacts and presses down the first end of the connecting rod 181.

[0094] As Figures 14a to 14f shown, a guiding inclined surface is provided at one end of the pushing block 114 facing the transmission inclined surface 115. The guiding inclined surface extends in the direction approaching the transmission inclined surface 115 in the up-and-down direction. During the process of the transmission member 11 driving the inner cover 30 to rotate from the locked state to the unlocked state, the lower end of the guiding inclined surface first contacts the first end of the connecting rod 181, and then the transmission member 11 moves to the upper end of the guiding inclined surface contacting the first end of the connecting rod 181, so that the first end of the connecting rod 181 is jacked up under the guiding action of the guiding inclined surface.

[0095] As Figures 14a to 14fAs shown, a pushing boss is provided on the upper surface of one end of the pushing block 114 away from the transmission inclined surface 115. When the transmission member 11 drives the inner cover 30 to rotate to the unlocking state, the first end of the connecting rod 181 abuts and cooperates with the pushing boss, so as to increase the lifting distance of the pushing block 114 to the first end of the connecting rod 181 and the lifting distance of the push rod 182 to the pressure limiting valve 44. A connecting rod inclined surface 1811 that cooperates with the transmission inclined surface 115 is provided at the first end of the connecting rod 181. By providing the connecting rod inclined surface 1811 at the first end of the connecting rod 181, when the transmission member 11 presses down the first end of the connecting rod 181 through the transmission inclined surface 115, the transmission inclined surface 115 and the connecting rod inclined surface 1811 are in sliding cooperation, so that the first end of the connecting rod 181 swings downward smoothly and steadily.

[0096] As Figures 14a to 14f shown, the connecting rod 181 and the push rod 182 are arranged at intervals in the transverse direction. A rib 1821 extending in the transverse direction is provided at the first end of the push rod 182, and the second end of the connecting rod 181 is pressed on the rib 1821. With the above structure, only by making the second end of the connecting rod 181 located above the rib 1821, the requirement that the second end of the connecting rod 181 presses down the first end of the push rod 182 can be met, reducing the height space occupied by the connecting rod 181 and the push rod 182 in the cover body, and making the structure of the cover body assembly compact. A fitting plate 1813 is provided at the second end of the connecting rod 181, and the fitting plate 1813 is pressed on the rib 1821. A bump 1822 that abuts against the pressure limiting valve 44 is provided at the second end of the push rod 182. By using the bump 1822 to abut and cooperate with the pressure limiting valve 44, it is possible to prevent the second end of the push rod 182 from scratching the pressure limiting valve 44 when lifting the pressure limiting valve 44.

[0097] As Figures 15a to 27 shown, in the embodiment where the exhaust pipe is eccentrically arranged relative to the inner cover, the outer cover 10 includes a lining 13 provided outside the inner cover 30 and a face cover 14 provided outside the lining 13. The transmission member 11 is movably provided on the lining 13. The handle 20 includes a second holding portion 22, and the second holding portion 22 is connected to the transmission member 11. A second avoidance hole for avoiding the second holding portion 22 is provided on the face cover 14, and the second holding portion 22 can drive the transmission member 11 to move. By using the face cover 14 to block the lining 13 and the structure provided on the outer surface of the lining 13, the user operates the portion of the second holding portion 22 located outside the face cover 14 and drives the transmission member 11 provided on the lining 13 to switch between the first position and the second position through the portion of the second holding portion 22 located inside the face cover 14.

[0098] As Figure 17 、 Figure 18 and Figures 20 to 27As shown, the transmission member 11 includes a swing rod 112, and the swing rod 112 is swingably arranged in a plane parallel to the bottom surface of the outer cover 10. The user operates the part of the second holding part 22 located outside the face cover 14, and drives the swing rod 112 to swing through the part of the second holding part 22 located inside the face cover 14. When the limiting member 40 is in the limiting position, the limiting member 40 can be in limiting cooperation with the swing rod 112 in the swinging direction of the swing rod 112.

[0099] Specifically, as Figure 21 , Figure 23 , Figure 25 and Figure 27 shown, a stop platform 1121 is arranged on the outer wall of the swing rod 112. When the limiting member 40 is in the limiting position, the limiting member 40 is in limiting cooperation with the stop platform 1121.

[0100] As Figure 17 , Figure 20 and Figure 24 shown, first limiting ribs 133 and second limiting ribs 134 are arranged at intervals on the outer wall of the inner liner 13. The swing rod 112 swings within the range between the first limiting rib 133 and the second limiting rib 134. When the swing rod 112 is in limiting cooperation with the first limiting rib 133, the transmission member 11 is in the first position. When the swing rod 112 is in limiting cooperation with the second limiting rib 134, the transmission member 11 is in the second position.

[0101] Another embodiment of the present utility model provides a cooking appliance, and the cooking appliance includes a cover body assembly, and the cover body assembly is the cover body assembly provided above. Applying the cooking appliance provided in this embodiment, when the inner cover 30 is installed on the outer cover 10, the driving column 31 passes through the driving hole 113, and the limiting member 40 is switched to the first avoidance position. The operating handle 20 is operated to enable the transmission member 11 to be switched between the first position and the second position, and drive the inner cover 30 to rotate relative to the outer cover 10. When the transmission member 11 is in the second position, the inner cover 30 is in the locked state, and the inner cover 30 is buckled with the pot body of the cooking appliance. When the transmission member 11 is in the first position, the inner cover 30 is in the unlocked state, and the inner cover 30 is separated from the pot body of the cooking appliance. The inner cover 30 can be disassembled relative to the outer cover 10. After the inner cover 30 is disassembled, the limiting member 40 is switched to the limiting position to limit the transmission member 11 in the first position, avoiding the user from misoperating the handle 20 and changing the position of the driving hole 113. Thus, when the inner cover 30 is installed again, the driving column 31 can be smoothly passed through the driving hole 113, and the inner cover can be smoothly installed on the outer cover.

[0102] In this embodiment, the pot body includes a heat preservation cover and an inner pot arranged in the heat preservation cover, and a pot tooth is arranged on the heat preservation cover.

[0103] The cooking appliance in this embodiment is a combined flip - type electric pressure cooker. The pot body further includes a housing arranged outside the heat - preservation cover. A hinge structure is provided between the housing and the cover assembly. A control circuit board is arranged inside the housing, and electrical components such as pressure control and temperature measurement are arranged inside the outer cover. The combined - type setting of the combined flip - type electric pressure cooker facilitates the wired connection between the electrical components inside the outer cover and the control circuit board inside the housing, ensuring the reliability of the electrical connection.

[0104] Since a hinge structure is provided between the housing and the cover assembly, when the cover assembly is opened from the pot body, the cover assembly stands upright on the housing as a whole. At this time, when disassembling the inner cover 30, the user operates the supporting member 60 to move the supporting member 60 from the supporting position to the avoiding position, and then pulls the inner cover 30. Thus, with the insertion block 33 as the swing point, the inner cover 30 swings away from the outer cover 10, causing the locking block 32 to disengage from the guide groove 15, and the inner cover 30 is inclined relative to the outer cover 10 to facilitate taking out the insertion block 33 from the sliding groove 17. Conversely, when installing the inner cover 30 on the outer cover 10, the insertion block 33 is inserted into the sliding groove 17, and the locking block 32 slides into the guide groove 15.

[0105] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
