The invention provides a dishwasher.

Referring to fig. 1, 2 and 8, the dishwasher includes a rack 10 and a sealing cover 20, the sealing cover 20 being movably coupled to the rack 10 to open or seal a tub (not shown). Specifically, the inner container of the dishwasher is provided with a cavity for mounting a bowl and basket assembly (not shown) of the dishwasher, and the outer surface of the inner container is provided with an opening communicated with the cavity, wherein the opening is used for mounting the bowl and basket assembly; before the dishwasher starts to work, the sealing cover 20 is moved to a position covering the opening relative to the bracket 10 to seal the inner container, so that water in the cavity is prevented from leaking out through the opening during the working process of the dishwasher; when the dishwasher is finished and the bowl and basket assembly needs to be taken out of the inner container, the sealing cover 20 moves relative to the bracket 10 to open the opening of the inner container, so that the bowl and basket assembly is convenient for a user to take out of the inner container.

Alternatively, the inner container of the dishwasher may be slidably connected to the rack 10, and the upper top of the inner container may have an opening, and after the inner container is pushed into the rack 10 along the X direction, the sealing cover 20 is located above the inner container, and the opening at the top of the inner container is sealed by moving and/or rotating the sealing cover 20 downward; when the bowl and basket assembly or the dishes in the inner container need to be taken out, the sealing cover 20 can be moved upwards and/or rotated upwards to open the opening at the top of the inner container, and then the inner container is pulled out of the support 10, so that the bowl and basket assembly or the dishes in the inner container can be conveniently taken out. Note that the seal cover 20 can move in the up-down direction; can also rotate along the up-and-down direction; the dishwasher can also move along the up-down direction and rotate along the up-down direction, and the dishwasher can be specifically determined according to the structure of the dishwasher, and is not limited here.

Of course, the inner container of the dishwasher may be fixedly connected to the bracket 10, and the inner container may be opened or sealed only by the movement of the sealing cover 20. In addition, the opening on the inner container can also be positioned at other positions of the inner container, and the position and the moving direction of the sealing cover 20 are correspondingly changed, which is not described again here.

In an embodiment, as shown in fig. 3, the dishwasher may include an elastic member 30, where the elastic member 30 is used to make the sealing cover 20 move toward the inner container to ensure that the sealing cover 20 can move to a position for sealing the inner container, so as to avoid a situation that the sealing cover 20 is locked with the bracket 10 and the sealing cover 20 cannot seal the inner container. Specifically, one end of the elastic member 30 may be connected to the sealing cover 20, and the other end of the elastic member 30 may be connected to the bracket 10, so that when the sealing cover 20 moves to a position for opening the liner, the elastic member 30 applies an elastic force to the sealing cover 20, and the elastic force is used to move the sealing cover 20 toward the liner. The elastic force applied by the elastic member 30 to the sealing cover 20 may be a pulling force or a pushing force, and may be determined according to the structure, position, etc. of the elastic member 30. In addition, when the sealing cover 20 is in the position for sealing the inner container, the elastic member 30 may or may not apply an elastic force to the sealing cover 20, and of course, the former can further improve the sealing performance of the sealing cover 20 against the inner container.

Of course, when the sealing cover 20 is located at the top of the inner container, the sealing cover 20 may be moved and/or rotated downward to the position for sealing the inner container only under the action of gravity, which may be determined by the weight and structure of the sealing cover 20.

In one embodiment, as shown in fig. 2, 4 and 5, the dishwasher may include a pushing member 40, wherein the pushing member 40 is used for abutting against the sealing cover 20 to drive the sealing cover 20 to move relative to the bracket 10, so that the sealing cover 20 opens or seals the inner container. The pushing piece 40 and the inner container can be arranged independently, so that the movement of the pushing piece 40 is separated from the movement of the inner container, the movement of the pushing piece 40 is not required to be driven through the inner container, the thrust required by pushing the inner container can be reduced, and the use is more convenient for a user. In addition, when the liner is fixedly connected with the bracket 10, the pushing member 40 can be additionally moved and the sealing cover 20 can be pushed to move by the driving mechanism 50 or manually, so as to open or seal the liner.

In one embodiment, as shown in fig. 5, a first inclined surface 401 may be provided on the pushing member 40, and when the pushing member 40 is controlled to move relative to the rack 10, the first inclined surface 401 is used for sliding abutting against the sealing cover 20 and pushing the sealing cover 20 to move, so that the sealing cover 20 opens or seals the inner container of the dishwasher. It can be understood that, the first inclined plane 401 is in sliding abutment with the sealing cover 20 to push the sealing cover 20 to interact with each other, so that the problem that the sealing cover 20 is clamped by the pushing member 40 or the bracket 10 due to displacement of the pushing member 40 in the process that the sealing cover 20 moves relative to the bracket 10 can be avoided, the movement of the sealing cover is smoother, and the liner can be better opened and sealed. In addition, by setting the inclination angle of the first inclined plane 401, the driving force required for driving the pushing member 40 to move can be reduced, so that the driving force requirement of the driving mechanism 50 for driving the pushing member 40 to move is reduced, the size of the driving mechanism 50 is reduced, or the structure of the driving mechanism 50 is simplified, and the cost of the driving mechanism 50 is reduced.

When the first inclined plane 401 is used for pushing the sealing cover 20 to move to a position for opening the liner, the pushing member 40 can be controlled to move in the reverse direction, so that the sealing cover 20 moves in the reverse direction to a position for sealing the liner under the action of gravity or the elastic member 30; when the first inclined plane 401 pushes the sealing cover 20 to move to the position for sealing the inner container, the pushing member 40 can be controlled to move in the reverse direction, so that the sealing cover 20 moves in the reverse direction to the position for opening the inner container under the action of gravity or the elastic member 30.

Alternatively, a second inclined surface may be provided on the sealing cover 20, and when the pushing member 40 moves relative to the bracket 10, the pushing member 40 abuts against the second inclined surface and pushes the sealing cover 20 to move, which is not described herein again.

It should be noted that the first inclined surface 401 may be provided only on the pusher 40, or the second inclined surface may be provided only on the seal cover 20; the first inclined surface 401 may be provided on the pushing member 40, and the second inclined surface may be provided on the sealing cover 20, which may be determined according to the structures of the pushing member 40 and the sealing cover 20.

Alternatively, the pushing member 40 may be slidably connected to the bracket 10, the first inclined surface 401 of the pushing member 40 may be inclined in a direction away from the sealing cover 20, and the first inclined surface 401 may extend in the sliding direction of the pushing member 40. Therefore, by controlling the pushing element 40 to slide relative to the bracket 10, the first inclined surface 401 on the pushing element 40 can be in sliding contact with the sealing cover 20, and the sealing cover 20 is pushed to move in the direction away from the pushing element 40, so that the sealing cover 20 opens the liner. Then, by controlling the pushing member 40 to slide in the opposite direction, the sealing cover 20 can move toward the direction close to the pushing member 40 under the action of gravity or the elastic member 30 to seal the inner container.

Alternatively, when the sealing cover 20 is provided with the second inclined surface, the second inclined surface on the sealing cover 20 may also be inclined toward a direction away from the pushing member 40 and extend along the sliding direction of the pushing member 40, which is not described herein again.

Of course, the pushing member 40 may also be rotationally connected with the bracket 10, and by driving the pushing member 40 to rotate, the first inclined surface 401 on the pushing member 40 is in sliding contact with the sealing cover 20, and pushes the sealing cover 20 to move; alternatively, the pushing member 40 is slidably abutted against the second inclined surface of the sealing cover 20 to push the sealing cover 20 to move.

In an embodiment, as shown in fig. 5, 13 and 14, the pushing element 40 may have a first retaining surface 402 for abutting against the sealing cover 20, the first retaining surface 402 is connected to one end of the first inclined surface 401 close to the pushing element 40, and the extending direction of the first retaining surface 402 is the same as the sliding direction of the pushing element 40, so that when the sealing cover 20 moves to the position of opening the inner container, the first retaining surface 401 abuts against the sealing cover 20 in a sliding manner. Accordingly, the component force of the reaction force of the seal cap 20 applied to the pusher 40 in the sliding direction of the pusher 40 is 0, that is, the reaction force of the seal cap 20 applied to the pusher 40 does not slide in the direction opposite to the pusher 40, and the pusher 40 does not slide by the action of the seal cap 20 even after the driving force for driving the pusher 40 to slide disappears, so that the stability of the pusher 40 is improved, and the driving mechanism 50 does not need to apply a driving force to the pusher 40 to maintain the position of the pusher 40, so that the structure of the driving mechanism 50 for driving the pusher 40 can be made simpler.

Alternatively, as shown in fig. 5, 11 and 12, the pushing member 40 may have a second holding surface 403 for abutting against the sealing cover 20, the second holding surface 403 is connected to one end of the first inclined surface 401 away from the pushing member 40, and the extending direction of the second holding surface 403 coincides with the sliding direction of the pushing member 40, so that when the sealing cover 20 moves to the position for sealing the inner container, the second holding surface 403 slidably abuts against the sealing cover 20. Thus, the reaction force of the seal cap 20 on the pusher 40 does not slide in the direction opposite to the pusher 40, and the pusher 40 does not slide by the seal cap 20 even when the driving force for driving the pusher 40 to slide disappears.

It will be appreciated that the pushing member 40 may have one of the first holding surface 402 and the second holding surface 403, or both the first holding surface 402 and the second holding surface 403, and of course, when the pushing member 40 has both the first holding surface 402 and the second holding surface 403, the driving mechanism 50 can drive the pushing member 40 and the sealing cover 20 more stably.

Similarly, when the sealing cover 20 has the second inclined surface, the sealing cover 20 may have a third retaining surface for abutting against the pushing member 40, the third retaining surface and the second inclined surface have one end connected to each other near the pushing member 40, and the extending direction of the third retaining surface coincides with the sliding direction of the pushing member 40, so that when the sealing cover 20 moves to the position of opening the liner, the third retaining surface abuts against the pushing member 40 in a sliding manner. And/or, a fourth holding surface used for abutting against the pushing piece 40 is arranged on the sealing cover 20, the fourth holding surface is connected with one end, away from the pushing piece 40, of the second inclined surface, and the extending direction of the fourth holding surface is consistent with the sliding direction of the pushing piece 40, so that when the sealing cover 20 moves to the position for sealing the liner, the fourth holding surface is in sliding abutting against the pushing piece 40. And will not be described in detail herein.

In an embodiment, as shown in fig. 8, the sealing cover 20 may include a sealing cover body 21, and a supporting frame 22 disposed at an edge of the sealing cover body 21, when the pushing member 40 moves relative to the bracket 10, the first inclined surface 401 on the pushing member 40 slidably abuts against the supporting frame 22 to push the sealing cover 20 to move, so as to prevent the first inclined surface 401 on the pushing member 40 from slidably abutting against other positions of the sealing cover 20 to affect the sealing performance of the sealing cover 20.

Or, when the sealing cover 20 is provided with the second inclined surface, the second inclined surface may be formed on the supporting frame 22, and the pushing member 40 has a pushing portion (not shown), and the pushing member 40 moves relative to the bracket 10, so that the pushing portion on the pushing member 40 is in sliding contact with the second inclined surface, and pushes the sealing cover 20 to move, which is not described herein again.

In one embodiment, as shown in fig. 4 and 5, the pushing member 40 may have a groove 404 on a side thereof adjacent to the sealing cover 20, and the first slope 401 may be formed on an inner surface of the groove 404. Thereby reducing the overall volume of pusher member 40. Moreover, the formation of the first and second retaining surfaces 402, 403 can be facilitated, thereby facilitating the processing of the pusher member 40.

Alternatively, as shown in fig. 4 and 5, the pushing member 40 may be disposed in a plate shape, and the pushing member 40 is recessed near the side surface of the sealing cover 20 to form a groove 404, so that the first inclined surface 401 is formed on the side surface of the pushing member 40, so as to improve the strength of the first inclined surface 401 on the pushing member 40, and enable the pushing member 40 to push the sealing cover 20 to move more stably. It can be understood that, by forming the groove 404 on the side face of the plate-shaped pushing member 40, the bending resistance of the pushing member 40 can be improved, and the problem that the pushing member 40 is bent by the reaction force of the sealing cover 20 when the pushing member 40 abuts against the sealing cover 20, so that the pushing member 40 is not smoothly moved, or the sealing cover 20 is not moved to the set position due to the bending of the pushing member 40, so that the sealing effect is poor is avoided.

Alternatively, as shown in fig. 5, a first flange 405 may be disposed on the pushing member 40 at a position corresponding to the groove 404, and the first flange 405 may form a supporting surface of the first inclined surface 401. Therefore, the width of the first inclined surface 401 can be increased, and the problem that the pushing member 40 cannot push the sealing cover 20 to move due to the fact that the part of the sealing cover 20 in sliding contact with the first inclined surface 401 falls off from the first inclined surface 401 due to the fact that the width of the first inclined surface 401 is too narrow is avoided.

Of course, the side of the pushing member 40 close to the sealing cover 20 may have an abutting protrusion, and the first inclined surface 401 may be formed on the upper surface of the abutting protrusion, which may be determined by the structures of the pushing member 40 and the sealing cover 20.

In an embodiment, the pushing members 40 may be respectively disposed on two opposite sides of the bracket 10 in the left-right direction, and the moving direction of the pushing members 40 may be made to coincide with the sliding direction of the inner container (the direction parallel to the X direction). Therefore, the space of the dishwasher can be fully utilized, and the problem that the volume of the dishwasher is overlarge due to the arrangement of the pushing piece 40 on the dishwasher is avoided. When the pushing member 40 is in a plate shape, the plate surface of the pushing member 40 and one side of the inner container can be arranged oppositely, that is, the two plate surfaces of the pushing member 40 face the left side and the right side of the pushing member 40 respectively, so as to reduce the width of the dishwasher along the left-right direction as much as possible.

In one embodiment, as shown in fig. 4, the number of the first inclined surfaces 401 on the pushing member 40 may be multiple, and the multiple first inclined surfaces 401 are distributed in sequence along the sliding direction of the pushing member 40. Therefore, when the pushing piece 40 pushes the sealing cover 20 to move, the acting force applied by the pushing piece 40 to the sealing cover 20 is distributed more evenly, so that the movement of the sealing cover 20 is smoother.

Similarly, when the sealing cover 20 is provided with a plurality of second inclined surfaces, the number of the second inclined surfaces on the sealing cover 20 may be multiple, and the plurality of second inclined surfaces are sequentially distributed along the sliding direction of the pushing member 40, so that the movement of the sealing cover 20 is smoother, and details are not repeated herein.

It should be noted that the pushing member 40 may have only a plurality of first inclined surfaces 401, the sealing cover 20 may have only a plurality of second inclined surfaces, or the pushing member 40 may have a plurality of first inclined surfaces 401 and the sealing cover 20 may have a plurality of second inclined surfaces, which may be determined by the structures of the pushing member 40 and the sealing cover 20.

The invention also provides an elastic piece.

In addition to any of the above embodiments, as shown in fig. 3 and fig. 11 to 14, one end of the elastic member 30 may be abutted against the support 10, and the other end of the elastic member 30 may be abutted against the sealing cover 20, so that when the sealing cover 20 moves to the position for opening the liner, the elastic member 30 applies an elastic force to the sealing cover 20, and the elastic force is used to move the sealing cover 20 toward the liner to ensure that the sealing cover 20 can move to the position for sealing the liner, thereby avoiding the situation that the sealing cover 20 is locked with the support 10 to cause the sealing cover 20 to be unable to seal the liner.

Specifically, when the sealing cover 20 is located on the top of the inner container, as shown in fig. 1 and 6, the bracket 10 further includes a top plate 12 located on the top of the sealing cover 20, one end of the elastic member 30 can be abutted against the lower surface of the top plate 12, and the other end of the elastic member 30 is abutted against the sealing cover 20, so that the elastic member 30 applies a downward elastic force to the sealing cover 20, and when the pushing force of the pushing member 40 on the sealing cover 20 disappears, the elastic force can push the sealing cover 20 to move downward, so as to ensure that the sealing cover 20 can seal the inner container. Of course, one end of the elastic member 30 may abut against the supporting bar 11, and the structure of the supporting bar 11 and the top plate 12 may be specifically determined.

Alternatively, a retaining structure 41 may be provided on the sealing cover 20, and the elastic member 30 may be clamped with the retaining structure 41, so that the elastic member 30 can stably abut against the sealing cover 20, and the part of the elastic member 30 abutting against the sealing cover 20 is prevented from falling off from the sealing cover 20 during the movement of the sealing cover 20.

Specifically, as shown in fig. 10, the elastic member 30 may be disposed in a rod shape, and the elastic member 30 has a holding section 301 that is engaged with the holding structure 41; the holding structure 41 of the sealing cover 20 includes an abutting portion 411 and a limiting portion 412, and the abutting portion 411 and the limiting portion 412 are respectively located at two sides of the holding section 301 to limit the movement of the holding section 301 along the arrangement direction of the abutting portion 411 and the limiting portion 412. When the sealing cover 20 moves to the position for opening the inner container, the elastic member 30 abuts against the bracket 10, and the holding section 301 of the elastic member 30 abuts against the abutting portion 411 to apply an elastic force to the sealing cover 20; the limiting portion 412 is used for limiting the movement of the holding section 301 in a direction away from the abutting portion 411, so that the holding section 301 of the elastic member 30 can stably abut against the abutting portion 411 in the moving process of the sealing cover 20.

It should be noted that the abutting portion 411 and the limiting portion 412 may be disposed opposite to each other, or may be disposed at two sides of the holding portion in a staggered manner, which may be determined according to the structures of the abutting portion 411 and the limiting portion 412. In addition, the relative distance between the abutting portion 411 and the limiting portion 412 may be smaller than or equal to the width of the holding section 301, or may be larger than or equal to the width of the holding section 301, which may be determined according to the structures of the holding structure 41 and the holding section 301.

Optionally, the number of the abutting portions 411 may be multiple, and the multiple abutting portions 411 are sequentially distributed along the extending direction of the holding section 301, so that the elastic force applied by the elastic member 30 to the sealing cover 20 is uniformly distributed, and the shaking generated during the movement of the sealing cover 20 is reduced.

In an embodiment, as shown in fig. 9, a first limiting protrusion 413 may be disposed on the abutting portion 411, and the first limiting protrusion 413 is located on a side of the retaining section 301 away from the sealing cover 20 to move the retaining section 301 of the elastic member 30 towards a direction away from the sealing cover 20, so that the connection between the elastic member 30 and the sealing cover 20 is more stable.
