To achieve the goals above, the technical solution of first aspect present invention provides a kind of damping door lock, for doing washing Machine, comprising: shell is equipped with first connecting portion；Damper is at least partially seated in the shell, for increasing the door closure The resistance being subject to during the shutdown process, the damper are equipped with the second connecting portion that can be rotated relative to the shell, and described One in second connecting portion and the first connecting portion can be connected with the body, another can be with the door closure phase Even, so that the door closure is articulated with the body；Lock core is mounted in the shell, and can be in the lock in the shell Positioning is set to be moved back and forth between unlocked position, and locks the second connecting portion when moving to the latched position to limit The second connecting portion is rotated relative to the shell, and is released when moving to the unlocked position to the second connecting portion Locking.

The damping door lock that the technical solution of first aspect present invention provides, door lock and damper are integrated, passed through Lock core to limit door closure rotation indirectly to the limitation of damper, so that function of locking a door is realized, because without in door closure and workbench Upper aperture avoids the problem of needing the leak to opening to carry out security protection in the prior art；And damper and door lock are integrated To damp door lock, damping function is had both and function of locking a door, so that the structure of washing machine is more compact, assembly efficiency is higher.

Specifically, damping door lock includes shell, damper and lock core, shell is equipped with first connecting portion, and damper is equipped with Second connecting portion, one in first connecting portion and second connecting portion is fixedly linked with door closure, another is fixedly linked with body, Due to second connecting portion can opposite shell rotation, to realize being rotatably connected for door closure and body；Damper can be Door closure increases the resistance that door closure is subject to during closing, to play damping action, slow down the speed of door closure closing, to avoid Door body closing velocity is too fast and situations such as generating noise or clamp hand；Lock core can move back and forth inside the shell, be hindered by locking The second connecting portion of Buddhist nun's device rotates to limit second connecting portion opposite shell, so that shell can only keep opposite with second connecting portion It is static, to realize function of locking a door.The specific working principle is as follows for it:

When lock core moves to latched position, second connecting portion is locked by lock core, is limited its opposite shell and is rotated in a circumferential direction, Since the first connecting portion on shell is fixedly linked with one in door closure and body, and the second connecting portion of damper and door closure It is fixedly linked with another in body, thus when the relative rotation between the second connecting portion and shell of damper is limited When, the relative rotation between door closure and body is also limited, it may be assumed that door closure cannot be freely rotated with respect to body, to realize lock Door function；Conversely, the locking to second connecting portion is released when lock core counter motion to unlocked position, so that the second connection It can relatively rotate between portion and shell, thus door closure can be opened and closed normally.Therefore, it locks a door in the application function Realization be to realize that lock core need to only move back and forth inside the shell can be realized lock by the cooperation between lock core and damper Door function and unlocking function, without being passed through as the prior art in the corresponding opening of the insertion door closure of the opening on workbench, The hole for opening up and locking a door on workbench and door closure thus is avoided, and then the leak progress safety avoided to opening is anti- Shield, solves the problems, such as door lock preventing water leakage in the prior art, and avoid water and enter inside door closure and workbench, has reached waterproof Security purpose is conceived very ingenious.

In addition, the damping door lock in above-mentioned technical proposal provided by the invention can also have following additional technical feature:

In the above-mentioned technical solutions, the damper includes: fixing piece, is mounted in the shell, and with the shell It matches, the fixing piece can be limited and rotated relative to the shell；And rotating member, it is mounted in the shell, and being capable of phase The shell is rotated, and is oppositely arranged with the fixing piece, and during the door closure is closed with the fixing piece phase Mutually only support friction；Wherein, the second connecting portion is fixedly linked with the rotating member.

Damper includes fixing piece and rotating member, and fixing piece is installed inside the shell, and the cooperation of itself and shell can limit Fixing piece opposite shell rotation, it may be assumed that fixing piece is nonrotatably mounted tO in shell, is protected with the movement of shell in circumferential direction Hold synchronization；Rotating member install inside the shell, and can opposite shell rotation, it may be assumed that rotating member is installed in rotation in shell；And Rotating member is oppositely arranged with fixing piece, and mutually only supports friction with fixing piece during door closure is closed, and is closed to slow down door closure The speed closed, thus the frictional force between fixing piece and rotating member can increase the resistance being subject in door closure closing process, into And realize the damping function of damper；And second connecting portion is fixedly linked with rotating member, thus second connecting portion and rotating member are protected Synchronous rotation is held, therefore also being capable of opposite shell rotation.

In the above-mentioned technical solutions, the lock core includes: locating part, can be reciprocatingly mounted in the shell, And it is matched with the shell to limit the lock core relative to the shell and rotate；And limit shaft, it is connected with the locating part, and Its cross section be it is non-circular, axis hole compatible with the limit shaft is equipped in the rotating member, the limit shaft is inserted into Or the abjection axis hole, to lock or unlock the second connecting portion.

Lock core includes locating part and limit shaft, and locating part can reciprocatingly be installed inside the shell, ensure that lock core energy It is enough to move back and forth between locked and unlocked positions, while the cooperation of locating part and shell limits between lock core and shell It relatively rotates, ensure that synchronism when lock core and shell move in circumferential direction；The cross section of limit shaft is non-circular Shape (such as rectangular, D-shaped, triangle, ellipse), rotating member is interior to be equipped with axis hole compatible with limit shaft, then the shape of axis hole It also is non-circular, thus when in limit shaft insertion axis hole, the relative rotation between lock core and rotating member can be limited.Due to lock Core is synchronous with the movement holding of shell in circumferential direction, and the movement of rotating member and second connecting portion in circumferential direction keeps same Step, thus when that cannot relatively rotate between lock core and rotating member, phase can not occur between shell and second connecting portion To rotation, it may be assumed that lock core has locked second connecting portion, limits the rotation of second connecting portion opposite shell；Conversely, when limit shaft is deviate from When axis hole, do not contacted between lock core and rotating member, so that rotating member can be rotated with opposite shell, thus second connecting portion It can also be relatively rotated with opposite shell, it may be assumed that lock core relieves the locking to second connecting portion.

Shape as locating part and its fit system between shell are not particularly limited, such as: locating part can be with For rectangular block, be equipped with slideway compatible with locating part in shell, locating part can only reciprocatingly slide along slideway and cannot phase It rotates to shell；Alternatively, locating part is semi-surrounding structure, the inner wall of shell is equipped with compatible with locating part half and wraps Closed structure, two semi-surrounding structures, which are docking together, constitutes square structure, and the two sides of square structure are correspondingly provided with support construction Or position limiting structure, it also can be realized the reciprocating movement of locating part, and limit the relative rotation between lock core and shell；..., This will not enumerate.

In the above-mentioned technical solutions, optionally, the fixing piece is described between the locating part and the rotating member Avoid holes are offered on fixing piece, the limit shaft passes through the avoid holes and is inserted into the axis hole.

Fixing piece is between locating part and rotating member, then limit shaft needs guiding through the axis that fixing piece could be inserted on rotating member Kong Zhong, therefore corresponding avoid holes are opened up in the middle part of fixing piece, to avoid limit shaft；At this point, the relatively close body of rotating member With the connecting portion of door closure, it is connected with body or door closure convenient for second connecting portion, and since to be located at rotating member remote for second connecting portion Side from fixing piece, thus will not influence each other between second connecting portion and fixing piece, so the structure of second connecting portion It can be simplified, and size and volume can accordingly reduce.

In the above-mentioned technical solutions, optionally, the rotating member is described between the locating part and the fixing piece Fixing piece is set in the second connecting portion, and can be rotated relative to the second connecting portion, and the second connecting portion passes through The fixing piece is connected with the body or the door closure.

Rotating member is between locating part and fixing piece, then the interconnecting piece of fixing piece relatively close body and door closure, thus Second connecting portion, which needs guiding through fixing piece, to be connected with body or door closure, therefore need to also open up in the middle part of fixing piece corresponding Hole to avoid second connecting portion, while also needing to guarantee to relatively rotate between second connecting portion and fixing piece, to guarantee It can relatively rotate between second connecting portion and shell, therefore the hole in the middle part of fixing piece is circular hole, and in second connecting portion At least one section is cylinder, to guarantee that fixing piece can be set in second connecting portion, and can be turned with respect to second connecting portion It is dynamic.

In any of the above-described technical solution, set on one in the outer peripheral edge of the inner wall of the shell and the fixing piece There is locating slot, another is equipped with locating piece, and the locating piece is embedded in the locating slot, and it is opposite can to limit the fixing piece The shell rotation.
