Anupper cover assembly 100 for acooking appliance 110 according to an embodiment of the present invention is described below with reference to fig. 1 to 11.

Referring to fig. 1 to 6, anupper cover assembly 100 for acooking appliance 110 according to an embodiment of the present invention may include: the upper cover comprises anupper cover body 10, alock cover 11, alinkage slide block 20, a push-pull rod 30 and atransmission mechanism 40.

Specifically, thelock cover 11 may be provided on theupper cover body 10, theinterlocking slider 20 may be provided on theupper cover body 10, and theinterlocking slider 20 may be connected to thelock cover 11. Theinterlocking slider 20 can rotate relative to theupper cover body 10, and further drives thelocking cover 11 to rotate between an opening position and a closing position. The push-pull rod 30 may be provided on theupper cover body 10, and the push-pull rod 30 may be pushed and pulled. One end of the push-pull rod 30 is anoperation end 31, one end of thetransmission mechanism 40 is connected with the other end of the push-pull rod 30, and thetransmission mechanism 40 is connected with theinterlocking slide block 20.

Therefore, when the push-pull rod 30 is pushed and pulled through the operatingend 31 of the push-pull rod 30, so that the push-pull rod 30 moves relative to theupper cover body 10, thetransmission mechanism 40 can transmit the movement of the push-pull rod 30 to the interlockingslide block 20, convert the linear motion into the rotary motion, rotate theinterlocking slide block 20 around the pivot axis, and drive thelock cover 11 to move between the cover opening position and the cover closing position when the interlockingslide block 20 rotates, so as to open and close the cover.

Here, it should be noted that "opening the lid" is not generally considered to open theupper lid assembly 100 to open the opening of the pot of thecooking utensil 110, and "closing the lid" is not considered to close the opening of the pot of thecooking utensil 110 to close theupper lid assembly 100. Instead, when the lockingcover 11 is located at the cover closing position, theupper cover assembly 100 can be matched with the pot body of thecooking utensil 110, and at the moment, theupper cover assembly 100 is locked and cannot move, and theupper cover assembly 100 cannot be separated from the pot body; when the lockingcover 11 is located at the uncovering position, theupper cover assembly 100 is disengaged from the pot body of thecooking utensil 110, and at the moment, theupper cover assembly 100 can move relative to the pot body so as to be separated from the pot body.

It should be noted that the structure for opening and closing the cover by the interlockingslider 20 is known to those skilled in the art and is not related to the invention of the present application, and will not be described in detail herein, and only the embodiment shown in the drawings is taken as an example for simple description, as shown in fig. 1 and fig. 2, theupper cover assembly 100 further includes alatch pin 12, an arc-shaped track is provided on theupper cover body 10, an open-to-position stop surface 101 and a close-to-position stop surface 102 are provided on the upper side of the arc-shaped track, and one end of the interlockingslider 20 connected to thetransmission mechanism 40 has aU-shaped groove 201. The lockingcover 11 is matched with the pot body, one end of the lockingpin 12 is connected with the lockingcover 11, and the other end of the lockingpin 12 penetrates through the arc-shaped track groove and is inserted in theU-shaped groove 201. When thelinkage sliding block 20 rotates around the pivot axis under the driving of thetransmission mechanism 40, the wall of theU-shaped groove 201 can act on the outer surface of the lockingpin 12, so that the lockingpin 12 moves along the arc-shaped track groove under the action of theU-shaped groove 201, and then the lockingcover 11 is driven to rotate to realize the matching and the separation of the locking cover and the pot body, and further the cover closing and the cover opening of theupper cover assembly 100 are realized. When theupper cover assembly 100 is opened in place, the end surface of the side of thelinkage slider 20 close to the push-pull rod 30 abuts against the opening-in-place stop surface 101, and when theupper cover assembly 100 is closed in place, the end surface of the side of thelinkage slider 20 far away from the push-pull rod 30 abuts against the closing-in-place stop surface 102.

In the related art, the upper cover of the pressure cooker is provided with an upper cover screwing hand, and the mode for driving the locking ring to be locked and unlocked is to rotate the upper cover screwing hand, but the upper cover screwing hand destroys the integrity of the surface of the upper cover and increases the height of the pressure cooker.

In the present invention, theupper cover assembly 100 converts the movement of the push-pull rod 30 into the rotation of the interlockingslide 20 through the cooperation of the push-pull rod 30, thetransmission mechanism 40 and the interlockingslide 20, and there is no need to additionally provide an upper cover handle on the upper surface of theupper cover assembly 100, the upper surface of theupper cover assembly 100 is smooth and complete, and the height of thecooking utensil 110 is smaller.

According to theupper cover assembly 100 for thecooking utensil 110 of the embodiment of the present invention, as shown in fig. 1 to 6, the push-pull rod 30 can move along the axial vertical plane of theupper cover body 10, and thus theoperation end 31 of the push-pull rod 30 can be located outside the side surface of theupper cover body 10, rather than above the upper surface of theupper cover body 10, which can further ensure that the height of thecooking utensil 110 is lower, and is more beneficial to reducing the height of thecooking utensil 110 and saving kitchen space.

According to some embodiments of the present invention, as shown in fig. 2-6, thetransmission mechanism 40 may include: afirst link 41 and astrut 42. One end of the push-pull rod 30 is theoperation end 31, thefirst connector 41 may be connected to the other end of the push-pull rod 30, and thefirst connector 41 may move along with the movement of the push-pull rod 30. The first connectingmember 41 may be provided with afitting slot 411, thepillar 42 is connected to the interlockingslider 20, and thepillar 42 extends into thefitting slot 411. When the first connectingmember 41 moves, the outer surface of thepillar 42 can abut against the groove wall of the matchinggroove 411, and thepillar 42 can move along the circumferential direction of theupper cover body 10 under the abutting action of the groove wall of the matchinggroove 411 to drive the linkingslide block 20 to rotate. Therefore, the translation of the push-pull rod 30 is converted into the rotation of the interlockingslide block 20, and the connecting structure is simple.

Further, as shown in fig. 2 and 3, the first connectingmember 41 may be formed as a connecting plate, and thefitting groove 411 may penetrate the connecting plate in the axial direction of theupper cover body 10, so that thestay 42 may pass through the connecting plate from below the connecting plate and extend to above the connecting plate. When the cover is opened and closed, the action positions of thesupport column 42 and the matchinggroove 411 are only a line which is formed by the contact of the outer surface of thesupport column 42 and the groove wall of the matchinggroove 411 and extends along the axial direction of theupper cover body 10, so that the friction between thesupport column 42 and the matchinggroove 411 is favorably reduced, the resistance of the cover is reduced, and the cover is opened and closed more easily and smoothly.

In addition, in the present invention, the length direction of the first connectingmember 41 may be perpendicular to the length direction of the push-pull rod 30, so that the movement of the push-pull rod 30 is transmitted to the first connectingmember 41 more easily. The engagingslot 411 may be formed in various shapes, alternatively, in some embodiments of the present invention, as shown in fig. 2 to 6, the engagingslot 411 may extend in a straight line shape along the length direction of the first connectingmember 41, in other embodiments of the present invention, the engagingslot 411 may extend in an arc shape along the length direction of the first connectingmember 41, which may satisfy the requirement that thepillar 42 moves under the resisting action of the wall of theengaging slot 411, and the resistance between thepillar 42 and the wall of the slot is small, so that thepillar 42 moves more smoothly in theengaging slot 411.

It should be noted that the connection mode of the first connectingmember 41 and the push-pull rod 30 and the connection mode of thepillar 42 and the interlockingslide block 20 are not particularly limited in the present invention, and only the requirements that the first connectingmember 41 is connected to the push-pull rod 30 and thepillar 42 is connected to the interlockingslide block 20 are satisfied. For example, the first connectingmember 41 and the push-pull rod 30 can be welded or bonded, and thepillar 42 and the interlockingslider 20 can be welded or bonded, so that the connection is more secure and reliable, and the damage is not easy to occur. For another example, the first connectingmember 41 and the push-pull rod 30 may be integrally formed, and thepillar 42 and the interlockingslider 20 may be integrally formed, so that the structure is simpler and the manufacturing is more convenient. For another example, the first connectingmember 41 and the push-pull rod 30 may be fixedly connected by a slot, a threadedfastener 44, etc., and thepillar 42 and the interlockingslider 20 may also be fixedly connected by a slot, a threadedfastener 44, etc., which are simple in connection and easy to disassemble and assemble, and are within the scope of the present invention.

According to some embodiments of the present invention, as shown in fig. 6, in a radial direction of theupper lid body 10 perpendicular to the push-pull direction of the push-pull rod 30, the extension dimension of thefitting groove 411 is L1, and the maximum distance of thestay 42 when theupper lid assembly 100 is in the open lid position and the closed lid position is T1. It should be noted that the illustration of two interlockingsliders 20 in fig. 6 does not mean that theupper lid assembly 100 includes two interlockingsliders 20, but is to display the positional relationship of theupper lid assembly 100 in the opening position and the closing position in a one-to-one correspondence manner for comparison.

When L1 is too small, thelid assembly 100 is not completely moved to the open position or the close position, thepillar 42 is moved to the end of theengaging slot 411 in theengaging slot 411, so that the interlockingslide 20 cannot continue to rotate, thelid assembly 100 cannot be opened or closed in place, and thecooking device 110 cannot be used normally. When L1 is too large, raw materials and installation space are wasted, which is not favorable for reducing cost and reasonably utilizing installation space.

Therefore, in order to ensure that the push-pull rod 30 pushes and pulls thelinkage slide block 20 to rotate in place and save the installation space, in the invention, T1+0.5mm is more than or equal to L1 is more than or equal to T1+10mm, so that when theupper cover assembly 100 is in the cover opening position and the cover closing position, thesupport column 42 does not move to the end part of the matchinggroove 411 in the matchinggroove 411, theupper cover assembly 100 can be completely opened or closed, the contact area between thesupport column 42 and the matchinggroove 411 when theupper cover assembly 100 is away from the cover opening position or the cover closing position can be reduced, the friction resistance is further reduced, and the cover opening and closing are smoother. For example, in some embodiments of the invention, the length of L1 is T1+1mm, T1+3mm, T1+5mm, T1+7mm, and the like.

When the push-pull rod 30 moves, one end of thesecond link 43 connected to the push-pull rod 30 moves along with the movement of the push-pull rod 30, and simultaneously, the other end of thesecond link 43 rotates relative to the end of thesecond link 43 connected to the push-pull rod 30, thereby driving the end of the interlockingslide 20 connected to thesecond link 43 to rotate. Therefore, the movement of the push-pull rod 30 is converted into the rotation of the interlockingslider 20, and the connection structure is simple.

Further, as shown in fig. 7 and 8, the second connectingmember 43 and the push-pull rod 30 may be connected by the cooperation of the first connectingshaft 431 and thefirst shaft hole 432, the first connectingshaft 431 may be provided on one of the push-pull rod 30 and the second connectingmember 43, and thefirst shaft hole 432 may be provided on the other of the push-pull rod 30 and the second connectingmember 43.

With continued reference to fig. 7 and 8, the first connectingshaft 431 may be provided with a first screw hole 433, and the first screw hole 433 may be used for installing a threadedfastener 44 to prevent the second connectingmember 43 from being loosened, so that the second connectingmember 43 is more firmly and reliably connected to the push-pull rod 30.

It should be noted that the connection manner of the first connectingshaft 431 and the push-pull rod 30 is not limited in the present invention, and only the requirement of connecting the first connectingshaft 431 and the push-pull rod 30 is satisfied. For example, the first connectingshaft 431 and the push-pull rod 30 may be welded, bonded or integrally formed, so that the connection is more secure and reliable and is not easily damaged. For another example, the first connectingshaft 431 and the push-pull rod 30 may be fixedly connected through a slot, a threadedfastener 44, etc., and the connection manner is simple and easy to disassemble and assemble, which is within the scope of the present invention.

In some embodiments of the present invention, as shown in fig. 7 and 8, the second connectingmember 43 and the interlockingslider 20 may be connected by the cooperation of the second connectingshaft 434 and thesecond shaft hole 435, the second connectingshaft 434 may be disposed on one of the interlockingslider 20 and the second connectingmember 43, and thesecond shaft hole 435 may be disposed on the other of the push-pull rod 30 and the second connectingmember 43. For example, in the embodiment shown in fig. 7 and 8, thelinkage slider 20 is provided with a second connectingshaft 434, the second connectingmember 43 is provided with asecond shaft hole 435, the second connectingshaft 434 is inserted into thesecond shaft hole 435 to connect the push-pull rod 30 and the second connectingmember 43, the second connectingshaft 434 rotates in thesecond shaft hole 435 to rotate the second connectingmember 43 relative to thelinkage slider 20, and the connection structure is simple and firm.

As shown in fig. 7 and 8, a second screw hole 436 may be disposed on the second connectingshaft 434, and the second screw hole 436 may be used for installing the threadedfastener 44 to prevent the second connectingelement 43 from being loosened, so that the second connectingelement 43 and the interlockingslider 20 are connected more firmly and reliably.

The connection mode of the second connectingshaft 434 and the interlockingslider 20 is not particularly limited, and the requirement of connecting the second connectingshaft 434 and the interlockingslider 20 can be met. For example, the second connectingshaft 434 and the interlockingslider 20 may be welded, bonded or integrally formed, so that the connection is more secure and reliable and is not easily damaged. For another example, the second connectingshaft 434 and the interlockingslider 20 can also be fixedly connected by a slot, a threadedfastener 44, etc., and the connecting manner is simple and easy to disassemble and assemble, which is within the protection scope of the present invention.

According to some embodiments of the present invention, as shown in fig. 11, in a radial direction of theupper lid body 10 perpendicular to the push-pull direction of the push-pull rod 30, the distance between the pivot axes of both ends of thesecond link 43 is L2, and the center distance of thesecond link shaft 434 when theupper lid assembly 100 is in the open lid position and the closed lid position is T2. It should be noted that the illustration of two interlockingsliders 20 in fig. 11 does not mean that theupper lid assembly 100 includes two interlockingsliders 20, but is for displaying the positional relationship of theupper lid assembly 100 in the opening position and the closing position in a one-to-one correspondence manner for comparison.

When thesecond link 43 is perpendicular to the push-pull rod 30, the distance between the end of thesecond link 43 connected to the interlockingslider 20 and the push-pull rod 30 is the largest in the radial direction of theupper lid body 10 perpendicular to the push-pull direction of the push-pull rod 30. When L2 is too small, thelid assembly 100 is not completely moved to the closed position, the second connectingmember 43 is already perpendicular to the push-pull rod 30, so that the linkingslide 20 cannot rotate, thelid assembly 100 cannot be closed in place, and thecooking utensil 110 cannot be used normally. When L2 is too large, raw materials and installation space are wasted, which is not favorable for reducing cost and reasonably utilizing installation space.

Therefore, in order to ensure that the push-pulllinkage sliding block 20 of the push-pull rod 30 rotates in place and save the installation space, in the invention, T2+0.5mm is not less than L2 is not less than T2+10mm, when theupper cover assembly 100 is in the cover closing position, the second connectingpiece 43 does not rotate to the position perpendicular to the push-pull rod 30, theupper cover assembly 100 can completely close the cover, when theupper cover assembly 100 is in the cover opening position, the included angle between the second connectingpiece 43 and the push-pull rod 30 is an obtuse angle, when theupper cover assembly 100 moves from the cover opening position to the cover closing position, the second connectingpiece 43 can smoothly rotate around the connecting end between the second connectingpiece 43 and the push-pull rod 30, so that the push-pull rod 30 is more labor-saving.
