The present invention is directed to solving at least one of the problems of the prior art or the related art.

To this end, one aspect of the present invention proposes a cover assembly.

Another aspect of the present invention is directed to a home appliance.

In view of the above, according to one aspect of the present invention, there is provided a cover assembly for a home appliance, including: a face cover provided with an exhaust valve hole; the exhaust valve seat is arranged in the exhaust valve hole, and the liquid accumulation surface of the exhaust valve seat is lower than the top surface of the side wall of the exhaust valve hole; the bottom wall of the water outlet is flush with the accumulated liquid surface of the exhaust valve seat or lower than the accumulated liquid surface of the exhaust valve seat.

According to the cover body assembly provided by the invention, the exhaust valve hole for mounting the exhaust valve seat is formed in the face cover, the drainage port is formed in the side wall of the exhaust valve hole, and the bottom wall of the drainage port is flush with or lower than the accumulated liquid level of the exhaust valve seat, so that the flowing path of the accumulated liquid in the exhaust valve hole is changed, liquid can be guided through the drainage port to flow laterally when the accumulated liquid is in the exhaust valve hole, and cannot flow downwards into the face cover, the cleaning is facilitated, and the problem that the part surface through which the liquid flows in the related technology cannot be cleaned completely to cause mildew and odor is solved.

In addition, according to the cover assembly in the above technical solution provided by the present invention, the following additional technical features may be further provided:

in the above technical solution, preferably, the width W of the drain opening is greater than or equal to a preset value, and a value range of the preset value is 1mm to 3 mm.

In this solution, the width W of the drain opening is defined. Through the width W more than or equal to the default of injecing the outlet, flow area when can ensure the liquid water conservancy diversion helps guaranteeing that liquid smoothly discharges and can not cause because of stifled liquid that the exhaust is obstructed or liquid flows out from other gaps.

In any of the above technical solutions, preferably, the cover assembly further includes: the metal cover is embedded in the face cover, and the face cover is of a hollow structure; the water outlet is arranged towards the exposed metal cover so as to guide the discharged liquid to the surface of the metal cover; or the water outlet is arranged far away from the exposed metal cover so as to guide the discharged liquid to flow to the water storage box of the household appliance through the surface of the surface cover.

In this technical scheme, lid subassembly is still including inlaying the metal lid of establishing in the face lid of fretwork, and the metal lid can bear high temperature, and intensity is high, can guarantee to cook and normally go on. The metal cover is sleeved with the surface cover, so that a handle is conveniently constructed for a user to hold, the user is protected from being scalded by the high-temperature metal cover in the cooking process or after the cooking is finished, optionally, the metal cover is a steel cover, and the surface cover is a plastic cover; the design of fretwork can reduce the face and cover the material, correspondingly, can produce two kinds of water conservancy diversion schemes because of the difference of outlet orientation, one is when the outlet orientation is naked metal covering, the downthehole hydrops of discharge valve can flow to naked metal covering surface through face lid surface, the metal covering is very high at culinary art in-process temperature, can directly evaporate the liquid that flows to its surface, even metal covering and face lid are made dirty by the soup that flows through its surface this moment, because of its dirty position all is in easily cleaning position, so also wash very easily after the dirt. When the water outlet is far away from the exposed metal cover, accumulated liquid in the exhaust valve hole can flow to the surface of the surface cover through the water outlet, then flow to the outer shell cover of the household electrical equipment, and then flow to the water storage box on the outer shell cover through the water outlet on the outer shell cover.

There is an exhaust valve lid assembly design among the electric pressure cooker of correlation technique, design into vertical limit with the inside wall of exhaust valve opening, in addition, many vertical muscle of exhaust valve lid lateral wall design, reserve a small amount of interference magnitude between this vertical muscle and the vertical limit of exhaust valve opening lateral wall, during the assembly, assemble in the exhaust valve opening with the exhaust valve lid of impressing by force, through the vertical muscle on the exhaust valve opening lateral wall extrusion exhaust valve lid, make vertical muscle warp a little, thereby make the exhaust valve lid firmly fix at exhaust valve opening top, can design into the exhaust valve lid and can 360 degrees assemblies often in this scheme. However, the temperature of parts contacted with high-temperature steam is increased when the exhaust valve exhausts, and due to the difference of product structure and material, the expansion amount of the exhaust valve cover and the expansion amount of the exhaust valve hole cannot be completely consistent in a hot state; when the expansion amount of the exhaust valve cover is smaller than that of the exhaust valve hole, the exhaust valve cover and the exhaust valve hole are extruded to be small during exhaust, and the exhaust valve cover is easy to flush out of the exhaust valve hole by water vapor. For solving this problem in the old scheme, often can do the cooperation height of exhaust valve opening and exhaust valve lid very high, need to do exhaust valve opening lateral wall very high promptly to ensure when exhaust valve exhausts, because of highly different and structure difference, the inflation of these two parts is different, so can appear some local cooperation pine but some local cooperation tightly, exhaust valve lid is in a stable elasticity and can not pop out from exhaust valve downthehole all the time with the cooperation of exhaust valve opening. In addition, in this scheme, because of the exhaust valve lid all can assemble for 360 degrees, so no matter when exhaust valve lid is in which assembly angle, the downthehole hydrops of exhaust valve should all be able to follow the gap between hydrops face and the outlet top of exhaust valve seat and flow out, for avoiding leading to the hydrops can't flow out because of the tension of water reason, need design the distance between hydrops face and the outlet top enough big, so this condition also need further heighten the lateral wall of exhaust valve opening on the basis that has originally very high. Because of the exhaust valve lid all uses exhaust valve opening top face to assemble as the holding surface, exhaust valve opening lateral wall too high can lead to exhaust valve lid assembling surface to uprise, exhaust valve lid top face is the peak of product usually, so the whole height of product can be very high when adopting this scheme, has just also led to the packing size of product too high to lead to the reduction of product dress cabinet quantity, make the whole cost of product high on the contrary, product competitiveness descends.

As shown in fig. 4 to 7, 9, 14, 15, 17, 19, 20, in one embodiment of the present invention, preferably, the cover assembly further includes: the exhaust valve cover 50 is buckled in the exhaust valve hole 30, the exhaust valve cover 50 is provided with a water flowing port 502, and when the exhaust valve cover 50 is buckled and connected with the exhaust valve hole 30, the water flowing port 502 is opposite to the water outlet.

In this embodiment, in order to solve the problem of the excessively high exhaust valve hole 30 in the related art, the exhaust valve cover 50 of the cover assembly is disposed to be in snap-fit connection with the exhaust valve hole 30, so that the assembly angle of the exhaust valve cover 50 is determined, and thus the scheme can achieve effective fixation of the exhaust valve cover 50 without making the side wall of the exhaust valve hole 30 very high as in the related art. On the basis, the exhaust valve cover 50 can be assembled in place when the angle is fixed, so the water flowing port 502 can be added at the bottom of the exhaust valve cover 50, and the side wall of the exhaust valve hole 30 does not need to be further heightened like in the related art, so that the height of the side wall of the exhaust valve hole 30 can be far smaller than that of the side wall of the exhaust valve hole 30 in the related art, and the assembly reference position of the exhaust valve cover 50 is lower than that of the related embodiment, so that the overall height of the product can be made shorter than that of the related art, the packaging size of the product can be reduced, the cabinet installing quantity of the product can be increased, the product cost is reduced, and the competitiveness of the product is enhanced. Optionally, as shown in fig. 19 and 24, the width L of the water flow opening 502 also needs to be greater than or equal to a preset value to ensure smooth water flow, and specifically, may be greater than the width W of the water discharge opening or may be smaller than the width W of the water discharge opening.

As shown in fig. 12, 21, 23 and 24, in one embodiment of the present invention, the water flow opening 502 is preferably configured as a water flow gap.

In this embodiment, the water flow opening 502 is configured as a water flow gap, i.e., the bottom of the water flow opening 502 is flush with the bottom of the exhaust valve cover 50, which further reduces the height of the exhaust valve cover 50.

As shown in fig. 3, 4, 9, 14, 15, 19, 20, in one embodiment of the present invention, the drain opening is preferably configured as a drain channel 302.

In this embodiment, the drain opening is configured as a drain channel 302, i.e., the top of the drain opening is flush with the top of the vent valve opening 30, further reducing the height of the vent valve opening 30.

In this embodiment, the outer surface of the water flow opening 502 on the exhaust valve cover 50 is provided with a limiting protrusion, and a 360-degree assembling manner of the exhaust valve cover 50 in the related art is changed into a fixed-angle insertion fastening manner, as shown in fig. 5, 8, and 10 to 13, a specific fastening structure is that at least two fastening barbs 506 are designed on the side wall of the exhaust valve cover 50, and a fastening hanging hole 304 matched with the fastening barbs 506 is designed on the side wall of the exhaust valve hole 30, as shown in fig. 4 and 8, the fastening hanging hole 304 may be a blind hole, and in the process of inserting the exhaust valve cover 50 into the exhaust valve hole 30, the limiting protrusion on the exhaust valve cover 50 is aligned with the drainage groove 302, so as to facilitate the user to align and install, and the limiting protrusion is embedded into the drainage groove 302 along with the movement of the exhaust valve cover 50, so as to play. After the assembly is completed, the fastening barb 506 on the exhaust valve cover 50 is fastened with the fastening hanging hole 304 in the exhaust valve hole 30, so that the exhaust valve cover 50 is completely fixed, meanwhile, the limiting protrusion plays an auxiliary circumferential limiting role, and the impact of high-pressure gas on the fastening structure in the circumferential direction in the exhaust process is reduced. In addition, the limiting protrusion ensures that the water flowing port 502 is opposite to the drainage groove 302, and the liquid can flow out conveniently by avoiding the port.

In one embodiment of the present invention, it is preferable that the number of the water flow ports 502 is at least one; when the number of the water flowing openings 502 is at least two, the number of the water discharging grooves 302 is more than or equal to that of the water flowing openings 502, the number of the buckling structures on the exhaust valve cover 50 and the exhaust valve hole 30 is more than or equal to that of the water discharging grooves 302, and the plurality of water discharging grooves 302 and the plurality of buckling structures are uniformly distributed along the circumferential direction of the exhaust valve hole 30; at most one drainage groove 302 is arranged between two adjacent buckling structures, and the positions of all the drainage grooves 302 relative to the buckling structures adjacent to the drainage grooves are the same.

Specifically, firstly, the number of the drain grooves 302 is ensured to be greater than or equal to that of the drain openings 502, so that the same drain opening 502 can face different drain grooves 302 along with the rotation of the exhaust valve cover 50; further, the quantity more than or equal to drainage tank 302 of lock structure, and a plurality of lock structures along the circumference evenly distributed of exhaust valve opening 30, make exhaust valve lid 50 have the lock direction that equals with lock structure quantity, only can set up a drainage tank 302 or not set up drainage tank 302 on exhaust valve opening 30 between two adjacent lock structures simultaneously, a plurality of drainage tank 302 that set up keep the same along the circumference evenly distributed of exhaust valve opening 30 and with adjacent lock structure's relative position, lock structure just in time can the lock when making drain 502 and drainage tank 302 relative. At this time, when the number of the drainage grooves 302 is greater than the number of the water flow openings 502, only the drainage grooves 302 opposite to the water flow openings 502 can drain water, and when the number of the drainage grooves 302 is equal to the number of the water flow openings 502, the plurality of water flow openings 502 and the plurality of drainage grooves 302 are uniformly distributed along the circumferential direction, so that each drainage groove 302 can correspond to one water flow opening 502, and each drainage groove 302 can drain water.

The arrangement of the snap structure, the drainage channel 302 and the drain opening 502 is described in four embodiments.

The concrete implementation is three:

four buckling hanging holes 304 and two drainage grooves 302 are arranged on the exhaust valve hole 30, the buckling hanging holes 304 are positioned on the quartering point of the exhaust valve hole 30, the two drainage grooves 302 are symmetrically distributed, the drainage grooves 302 avoid the buckling hanging holes 304, one or two drain openings 502 are arranged on the exhaust valve cover 50 corresponding to the drainage grooves 302, and two installation directions of the exhaust valve cover 50 are formed.

The fourth concrete embodiment:

four buckling hanging holes 304 and four drainage grooves 302 are arranged on the exhaust valve hole 30, the buckling hanging holes 304 and the drainage grooves 302 are all positioned on the quartering point of the exhaust valve hole 30, the drainage grooves 302 avoid the buckling hanging holes 304, one, two, three or four water flowing ports 502 are arranged on the exhaust valve cover 50 corresponding to the drainage grooves 302, and four installation directions of the exhaust valve cover 50 are formed.

As shown in fig. 9 to 11 and 13, in one embodiment of the present invention, the stopper protrusion preferably includes two stopper protrusions 504 spaced apart from each other in the circumferential direction of the exhaust valve cover 50.

In this embodiment, it is specifically defined that the limiting protrusion is composed of two limiting protrusions 504 arranged at intervals along the circumferential direction of the exhaust valve cover 50, and the space between the two protrusions is configured as an avoiding opening, so that the structure is simple, on one hand, the height requirement of the exhaust valve cover 50 is reduced, on the other hand, the flow area of the avoiding opening is enlarged as much as possible, and the obstruction to the discharged liquid is reduced to the greatest extent.

As shown in fig. 14 to 30, in an embodiment of the present invention, at least one pair of fastening holes 508 and fastening notches 510, which are circumferentially communicated with each other, are preferably formed on one of the exhaust valve hole 30 and the exhaust valve cover 50, and the plurality of pairs of fastening holes 508 and fastening notches 510 are spaced apart from each other; the other of the exhaust valve hole 30 and the exhaust valve cover 50 is provided with a fastening protrusion 306 protruding toward the other, and the fastening protrusion 306 is inserted into the fastening notch 510 and screwed into the fastening hole 508 along with the movement and rotation of the exhaust valve cover 50.

In this embodiment, the 360-degree assembly of the exhaust valve cover 50 in the related art is changed to a fixed-angle rotation fastening manner, and specifically, the fastening structure includes at least one pair of fastening holes 508 and fastening notches 510 and at least one fastening protrusion 306, which are adapted to the pair of fastening holes 508 and fastening notches 510, and the plurality of pairs of fastening holes 508 and fastening notches 510 are spaced apart from each other. During assembly, as the exhaust valve cap 50 moves downward, the fastening protrusion 306 is gradually inserted into the fastening notch 510, and when the exhaust valve cap 50 is rotated, the fastening protrusion 306 rotates into the fastening hole 508, thereby completing the assembly. By reasonably designing the position of the water flowing port 502 at the bottom of the exhaust valve cover 50, after the exhaust valve cover 50 rotates to the right position, the water flowing port 502 at the bottom of the exhaust valve cover 50 just faces the water outlet on the side wall of the exhaust valve hole 30, so that accumulated liquid in the exhaust valve hole 30 can flow from the water flowing port 502 to the water outlet and finally flows out of the exhaust valve hole 30. By adopting the buckling mode, a user does not need to pay large pressing force during installation, and only needs to align the buckling protrusion 306 with the buckling notch 510 to place the buckling protrusion into the exhaust valve cover 50 and rotate, so that the risk of damaging the buckling structure when the user applies force improperly is reduced. Optionally, as shown in fig. 18 and 21, when the fastening hole 508 and the fastening notch 510 are disposed on the exhaust valve cover 50, the fastening hole 508 is a blind hole, i.e., does not penetrate through the sidewall of the exhaust valve cover 50, and the fastening notch 510 does not penetrate through the sidewall of the exhaust valve cover 50, so as to prevent effusion from flowing out from the gap between the fastening hole 508 and the fastening protrusion 306 and the fastening notch 510, which causes inconvenience in cleaning. The snap holes 508 and snap notches 510 may be positioned on the vent opening 30 to ensure that the outer side wall of the vent opening is flat.

In one embodiment of the present invention, preferably, the snap protrusions 306 are provided on the exhaust valve cover 50; the drain port is configured as a drain tank 302; the width D of the catching indentation 510, the width D of the catching protrusion 306, and the width W of the drain opening satisfy D > D > W.

In this embodiment, the fastening protrusion 306 is disposed on the outer sidewall of the exhaust valve cover 50, and the fastening hole 508 and the fastening indentation 510 are disposed on the sidewall of the exhaust valve hole 30, so that the alignment between the fastening protrusion 306 and the fastening indentation 510 is easy to observe during installation, and the operation is convenient. By configuring the drain opening as the drain groove 302 at this time, the height of the vent valve hole 30 can be further reduced. When the exhaust valve cap 50 is rotatably assembled, since the width D of the catching recess 510, the width D of the catching protrusion 306 and the width W of the drain opening are sequentially reduced, when the snap-fit protrusion 306 is rotated to the top of the drain groove 302, the exhaust valve cap 50 cannot be pressed downward, the assembly cannot be rotated after the insertion, only when the catching protrusion 306 is rotated to the top of the catching recess 510, the exhaust valve cap 50 can be downwardly assembled at this time because D < D, the exhaust valve cover 50 is then rotated to snap over the exhaust valve opening 30, such that a user may place the exhaust valve cover 50 on top of the exhaust valve opening 30 of the face cap 10 without intentionally aligning the snap features, the exhaust valve cap 50 is then rotated and pressed downward or naturally falls by the gravity of the exhaust valve cap 50, after the snap protrusions 306 are inserted into the snap notches 510, the exhaust valve cap 50 is rotated to complete the assembly.

In one embodiment of the present invention, preferably, the snap protrusions 306 are provided on the inner side wall of the exhaust valve hole 30; the flow opening 502 is configured as a flow gap; the width D of the catching notch 510, the width D of the catching protrusion 306, and the width L of the water flow notch satisfy D > L.

In this embodiment, the latching protrusion 306 is disposed on the inner sidewall of the vent hole 30, and the latching hole 508 and the latching notch 510 are disposed on the sidewall of the vent cover 50, so that the appearance of the vent hole 30 is neat. At this time, the drain port 502 is configured as a drain notch, and the height of the exhaust valve cover 50 can be further reduced. When the exhaust valve cover 50 is assembled in a rotating manner, because the width D of the fastening notch 510, the width D of the fastening protrusion 306 and the width L of the water flowing notch are sequentially reduced, when the water flowing notch rotates to the top of the fastening protrusion 306, the exhaust valve cover 50 still cannot be pressed downwards, the situation that the assembly cannot be rotated after the assembly is inserted is avoided, only when the fastening notch 510 of the exhaust valve cover 50 rotates to the top of the fastening protrusion 306 in the exhaust valve hole 30, the exhaust valve cover 50 can be assembled downwards due to D < D, and then the exhaust valve cover 50 is rotated to fasten the exhaust valve hole 30 to complete the assembly.

As shown in fig. 21, fig. 22, fig. 24, and fig. 25, in an embodiment of the present invention, preferably, the plurality of pairs of fastening holes 508, fastening notches 510, and the plurality of water flow openings 502 are uniformly distributed along the circumferential direction of the exhaust valve cover 50, and the number of the fastening notches 510 and the fastening holes 508 is equal to the number of the water flow openings 502, and is greater than or equal to the number of the fastening protrusions 306; the number of the water discharge ports is equal to or less than the number of the water discharge ports 502.

In this embodiment, the plurality of pairs of fastening holes 508 and fastening notches 510 are uniformly distributed along the circumferential direction of the exhaust valve cover 50, so that several pairs of fastening holes 508 and fastening notches 510 are provided, the exhaust valve cover 50 has several optional installation angles, and at this time, the same number of water flow ports 502 are provided and uniformly distributed along the circumferential direction, so that it is ensured that the water flow ports 502 are opposite to the water discharge port regardless of the installation angle, and the liquid smoothly flows out, and the number is greater than or equal to the number of the fastening protrusions 306, so that the fastening fit is ensured by reasonably setting the positions of the fastening protrusions 306, and the number of the fastening protrusions 306 can be reasonably reduced as required, thereby simplifying the structure. Specifically, when the number of the fastening protrusions 306 is equal to that of the fastening holes 508, the fastening protrusions 306 are uniformly distributed along the circumferential direction and occupy equal division points, and when the number of the fastening protrusions 306 is smaller than that of the fastening holes 508, the positions can be arbitrarily selected from the equal division points, preferably symmetrical or approximately symmetrical positions, so as to ensure the stability of the connection. The number of the water outlets can be less than or equal to that of the water outlets 502, on the basis of ensuring that each water outlet is provided with the communicated water outlets 502, a reasonable number of water outlets can be arranged according to the requirement of water flow, and the positions of the water outlets can also be arranged according to the expected accumulated liquid discharge direction.
