The embodiment of the invention relates to the technical field of household appliances, in particular to a household appliance.

Background

For the purposes of sectional storage, ease of operation, etc., the household appliance is usually provided with one or more drawers, which are supported within the household appliance by means of sliding rails and can be pulled out or pushed back along the sliding rails.

In the prior art, when the drawer is pulled out to the maximum travel distance during the use of the drawer and the sliding rail system for the household appliance, the gravity center of the drawer exceeds the front end of the sliding rail, and a gap exists between the rear end of the drawer and the sliding rail, so that the front end of the drawer is inclined downwards and sinks downwards.

This sinking is exacerbated if the drawer carries more storage. Excessive sinking of the front end of the drawer can cause the drawer to collide with other components of the household appliance located below the drawer, thereby affecting the normal use of the household appliance.

Disclosure of Invention

It is an aim of embodiments of the present invention to provide an improved domestic appliance.

Accordingly, an embodiment of the present invention provides a domestic appliance comprising: a storage compartment having a pick-and-place opening; a drawer having a first sliding portion, the drawer being located within the storage compartment and being drawn out of or pushed back into the storage compartment; and a guide rail located within the storage compartment, the guide rail having a sliding slot along which the first sliding portion is adapted to slide; wherein the sliding groove includes a chute portion inclined in a sinking direction of the drawer along a drawing direction of the drawer.

By adopting the scheme of the embodiment, the inclined groove part inclined towards the sinking direction of the drawer is arranged at the front end of the guide rail, so that the sinking amount of the front end when the drawer is pulled out can be reduced. The reduction of the amount of sinking is advantageous to avoid the front end of the drawer colliding with other parts of the household appliance when the drawer is pulled out. Wherein, the front end of the guide rail is the end close to the storage chamber taking and placing opening.

Optionally, the chute portion has an upper chute wall, and the upper chute wall is inclined toward the sinking direction along the pulling-out direction. When the first sliding part slides to the front end of the guide rail along the pulling-out direction, the front end of the drawer sinks under the action of gravity, and the first sliding part synchronously moves towards the direction opposite to the sinking direction. The upward movement distance of the first sliding part is limited by the declined upper groove wall to be reduced, so that the downward inclination distance of the front end of the drawer is also reduced.

Optionally, the upper groove wall is linear, arc or step-shaped. Particularly, when the upper groove wall is linear, the whole movement of the drawer can be smooth when the drawer is pulled out of the storage chamber, and a user does not feel that the display is blocked clearly.

Optionally, the guide rail includes a stop structure adapted to stop the drawer after the drawer is pulled out by a predetermined degree, and the first sliding portion is located in the chute portion when the drawer is stopped. Therefore, the maximum movement stroke of the drawer along the pulling-out direction is limited through the stop structure, and the drawer is prevented from being completely pulled out of the storage chamber.

Optionally, when the drawer is stopped, the first sliding portion abuts against an upper groove wall of the chute portion, and the drawer is supported by a second sliding portion located in front of the chute portion. Therefore, the front end of the drawer naturally sinks and the first sliding part synchronously tilts reversely by taking the second sliding part as a fulcrum. In this process, since the chute portion is inclined in the pull-out direction toward the sink direction, the first sliding portion tilted in the reverse direction can be brought into abutment with the upper groove wall of the chute portion earlier. Further, the first sliding part and the chute part which are abutted against each other can prevent the front end of the drawer from continuously sinking. In addition, the first sliding part can be abutted against the inclined groove part only by a small stroke of reversely tilting, so that the sinking amount of the front end of the drawer can be effectively reduced.

Optionally, in the pull-out direction of the drawer, a distance from an intersection point of the chute portion and the other portion of the chute to the stop structure is greater than a distance from the first sliding portion to the stop portion of the drawer, wherein the stop portion of the drawer is adapted to cooperate with the stop structure to stop the drawer. Therefore, the first sliding part can be positioned in the inclined groove part when the drawer is stopped, and the purpose of reducing the sinking amount of the front end of the drawer is achieved.

Optionally, an inclination angle of the chute portion inclining to the sinking direction along the pull-out direction is 3 degrees to 10 degrees, and/or a length of the chute portion along the pull-out direction of the drawer is at least one third of a length of the chute portion along the pull-out direction of the drawer. Through the angle of declination of rational design chute part and the length of chute part for when realizing reducing the heavy effect of sinking, ensure that the user can not produce obvious pause and feel when pulling the drawer, optimize user experience.

The entrance section is in a horn mouth shape, and the first sliding part of the drawer is favorably arranged in the sliding groove, so that the drawer is convenient to assemble.

Optionally, the first sliding part includes a first roller rotatably disposed on the drawer. From this, first gyro wheel is suitable for and supports the drawer and rolls on the spout to avoid drawer and spout dry friction, make the user can more smoothly pull the drawer.

Optionally, the sliding groove includes a horizontal section located behind the chute portion in the pull-out direction of the drawer, and a lower groove wall of the horizontal section is parallel to the horizontal direction. The horizontal section is thereby adapted to support the drawer being pulled out or pushed back into the storage compartment in a substantially horizontal direction and to guide the drawer to move to the chute portion when the drawer is pulled out.

Optionally, the sliding groove has an inclined portion at a rear end in a pull-out direction of the drawer, and the inclined portion is inclined in the sinking direction in a push-back direction of the drawer. Thus, the drawer pushed back to the inclined portion along the slide groove has a tendency to continue to automatically move into the storage compartment, so that the drawer can automatically move to a final position after being pushed back to a predetermined degree.

Optionally, at least part of the stroke of the first sliding part in the chute part is in contact with the upper chute wall of the chute part, so that the rear end of the drawer is limited to continue tilting upwards, and then the first sliding part acts on the front end of the drawer to reduce the sinking amount.

Detailed Description

As background art, when a drawer of a conventional home appliance is pulled out of a storage compartment, the front end of the drawer greatly sinks under the action of gravity, and is easily damaged due to collision with other components of the home appliance.

To solve the above technical problem, an embodiment of the present invention provides a home appliance, including: a storage compartment having a forward opening; a drawer having a first sliding portion, the drawer being located within the storage compartment and being drawn out of or pushed back into the storage compartment; and a guide rail located within the storage compartment, the guide rail having a sliding slot along which the first sliding portion is adapted to slide; wherein the sliding groove includes a chute portion inclined in a sinking direction of the drawer along a drawing direction of the drawer.

By adopting the scheme of the embodiment, the inclined groove part inclined towards the sinking direction of the drawer is arranged at the front end of the guide rail, so that the sinking amount of the front end when the drawer is pulled out can be reduced. The reduction of the amount of sinking is advantageous to avoid the front end of the drawer colliding with other parts of the household appliance when the drawer is pulled out. Wherein, the front end of the guide rail is the end close to the opening of the storage room.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Fig. 1 is a partial schematic view of a household appliance according to an embodiment of the present invention.

To show the embodiment more clearly, fig. 1 is only shown by way of example for the region of the household appliance in which the drawer is located.

The household appliance in the embodiment can be a refrigerating/freezing box, and can also be a dishwasher, a wardrobe and the like.

In particular, with reference to fig. 1, the household appliance 1 may comprise: a storage chamber 10, the storage chamber 10 having a forward access opening 101.

Further, the household appliance 1 may further comprise: a drawer 11 having a first sliding portion 110 (as shown in fig. 4 and 5), the drawer 11 being located inside the storage chamber 10 and being pulled out or pushed back into the storage chamber 10.

The width direction of the household appliance 1 is referred to as the x direction, the depth direction is referred to as the y direction, and the height direction is referred to as the z direction. The drawer 11 can be pulled out or pushed back into the storage compartment 10 in the y-direction. The storage chamber 10 has a forward access opening 101 which is an access opening 101 opened to the front side of the household appliance 1 in the pull-out direction of the drawer 11, wherein the front side of the household appliance 1 is the side facing the user when in use, and in fig. 1, the front side is the y direction.

The drawer 11, which is pushed back into the storage compartment 10 in the opposite direction of y, is adapted to close the access opening 101 of the storage compartment 10. The drawer 11 pulled out of the storage chamber 10 in the y direction is adapted to expose the access opening 101, and the drawer 11 may have an upward opening (not shown) through which a user can access the storage placed in the drawer 11 and can put the storage into the drawer 11.

In one variation, the drawer 11 may be a drawer door slidably supported by the rails 12 and adapted to open or close the access opening 101 of the storage compartment 10 in a push-pull manner. When the access port 101 is opened, the stored material can be placed in or taken out of the cavity exposed by the access port 101.

Further, referring to fig. 2 and 3, the household appliance 1 may further include a rail 12, the rail 12 being located inside the storage chamber 10, the rail 12 may have a slide groove 120, and the first sliding portion 110 may be adapted to slide along the slide groove 120.

For example, the guide rail 12 may be made of a plastic material.

Further, the chute 120 may include a chute portion 121 inclined in a sinking direction of the drawer 11 in a drawing direction (illustrated y direction) of the drawer 11. Wherein fig. 2 is a schematic view of a guide rail 12 of the household appliance 1 shown in fig. 1; fig. 3 is a side view of the guide rail 12 shown in fig. 2.

The sinking direction of the drawer 11 may be the direction of gravity. For drawers 11 that are pulled out of or pushed back into the storage compartment 10 in the y-direction as shown in FIG. 1, the direction of depression of the drawer 11 may be the opposite of the z-direction as shown.

In one embodiment, the number of the guide rails 12 may be two, and the two guide rails 12 are oppositely disposed on the left and right inner sidewalls of the storage room 10 along the x direction, and fig. 4 and 5 show a combination of the guide rails 12 on one side of which the drawer 11 is supported. Wherein fig. 4 is a schematic view of the household appliance 1 of fig. 1 when the drawer 11 is pushed back into the storage compartment 10 along the rails 12 of fig. 2; fig. 5 is a schematic view of the drawer 11 of the household appliance 1 shown in fig. 1 being pulled out of the storage compartment 10 along the rail 12 shown in fig. 2.

In one embodiment, the extending direction of the sliding groove 120 may be substantially parallel to the drawing direction (shown as y direction) of the drawer 11, so that the drawer supported on the rail 12 by the first sliding portion 110 can be smoothly drawn out or pushed back to the storage chamber 10.

In one embodiment, the sliding groove 120 may have an opening 122 facing the drawer 11, and the first sliding part 110 extends from the opening 122 and is supported on the sliding groove 120, so that the first sliding part 110 can effectively support the drawer 11 to slide along the sliding groove 120.

In one implementation, the first sliding portion 110 may include a first roller 111 rotatably disposed at the drawer 11. Thus, the first roller 111 is adapted to support the drawer 11 to roll on the sliding groove 120, so as to avoid dry friction between the drawer 11 and the sliding groove 120, and enable a user to pull the drawer 11 more smoothly.

In a variation, the first sliding portion 110 may include a flange bent from an upper edge of a side wall of the drawer 11 in a direction away from the opening of the drawer 11, the flange being supported by the sliding groove 120 and being slidable back and forth on the sliding groove 120 in the y direction.

In one embodiment, the drawer 11 has a front end 11a and a rear end 11b opposite to each other along the y-direction, wherein the front end 11a is an end of the drawer 11 close to the access opening 101 when the drawer 11 is located in the storage compartment 10, and the rear end 11b is an end of the drawer 11 far from the access opening 101 when the drawer 11 is located in the storage compartment 10.

The guide rail 12 has a front end 12a and a rear end 12b opposite to each other in the y direction, wherein the front end 12a is an end close to the access opening 101 of the storage chamber 10, and the rear end 12b is an end far from the access opening 101.

In one implementation, the first sliding portion 110 may be disposed at the rear end 11b of the drawer 11.

In one implementation, rail 12 may be provided with one or more mounting holes 123 adapted to secure rail 12 to an interior side wall of storage compartment 10. For example, the rail 12 may be fixed to the storage room 10 through the mounting hole 123 in a direction such as a bolt fixing direction.

Taking the household appliance 1 as an example of a refrigerator, the guide rail 12 can be fixed to the inner liner of a refrigerating chamber or a freezing chamber.

In one implementation, the chute portion 121 may have an upper chute wall 124, the upper chute wall 124 being inclined in the pull-out direction (shown as the y-direction) to the sink-down direction (shown as the reverse of the z-direction) to form a guide surface extending obliquely downward in the y-direction.

When the first sliding portion 110 slides in the pull-out direction (y direction in the figure) to the front end 12a of the guide rail 12, the front end 11a of the drawer 11 sinks by gravity, and the first sliding portion 110 moves in a direction (z direction in the figure) opposite to the sinking direction in synchronization. The distance that the first sliding portion 110 moves upward is limited by the downwardly inclined upper groove wall 124 to be reduced, so that the distance that the front end 11a of the drawer 11 is downwardly inclined is also reduced.

In one embodiment, the upper slot wall 124 can be straight, as shown in fig. 3, so that the overall movement of the drawer 11 is smooth during the drawing out of the storage compartment 10, and the user does not feel a display jam.

In one variation, the upper slot wall 124 may also be arcuate in shape extending in a generally downward sinking direction along the y-direction, and the arcuate shape may be convex toward the sinking direction. Alternatively, the arc may be convex in the illustrated z-direction.

In a variation, the upper slot wall 124 may also be stepped extending in the y direction and substantially toward the sinking direction, so as to reduce the sinking amount of the front end 11a of the drawer 11 and achieve a certain deceleration effect, thereby preventing the drawer 11 from being pulled too fast to cause a safety accident.

In one implementation, the sliding groove 120 may have a substantially constant cross section to ensure that the first sliding portion 110 can smoothly slide along the sliding groove 120, and to facilitate reducing the complexity of the mold and optimizing the manufacturing process. The cross section is a section on a plane formed by the x direction and the z direction.

In one implementation, chute 120 has opposing upper and

lower chute walls

120a, 120b along the z-direction. For any point of the chute 120 in the y-direction, the distance from the upper slot wall 120a to the lower slot wall 120b of the chute 120 in the z-direction may be substantially the same.

The first sliding part 110 is mostly supported by the lower groove wall 120b of the sliding groove 120 and slides along the lower groove wall 120b during the drawer 11 is pulled out or pushed back to the storage chamber 10.

When the drawer 11 moves in the pull-out direction to the point where the center of gravity is beyond the rail 12, the drawer 11 sinks by gravity, so that the first sliding portion 110 is tilted in the z-direction and comes into contact with the upper groove wall 120a of the slide groove 120.

As the drawer 11 continues to move in the pull-out direction, the first sliding portion 110 slides along the upper groove wall 120a of the chute 120 to the upper groove wall 124 of the chute portion 121. Of course, the length of the chute part 121 in the y direction may be adapted so that the first slider 110 just switches to the upper chute wall 124 of the chute part 121 when separating from the lower chute wall 120b of the chute 120.

In one implementation, the upper slot wall 124 of the chute portion 121 may be formed by the upper slot wall 120a of the chute 120. For example, for the upper slot wall 120a of the chute 120 extending in the y-direction, the direction of extension of the upper slot wall 120a at the middle of the chute 120 and at the portion near the rear end 12b of the rail 12 may be substantially parallel to the horizontal direction (as shown in the y-direction), and the upper slot wall 120a at the portion of the chute 120 near the front end 12a of the rail 12 is adapted to form the upper slot wall 124 of the chute portion 121.

In a variation, the upper groove wall 124 of the chute portion 121 may be a separate baffle plate and engage with the upper groove wall 120a of the chute 120. For example, the end of the upper groove wall 124 of the chute portion 121 remote from the front end 12a of the guide rail 12 may be connected to the upper groove wall 120a of the chute 120, and the end of the upper groove wall 124 of the chute portion 121 near the front end 12a of the guide rail 12 extends in the sinking direction. Thereby, the chute part 121 can be mounted to the guide rail of the existing home appliance in a separate assembly.

In one implementation, the rail 12 may include a stop structure 125, and the stop structure 125 may be adapted to stop the drawer 11 after the drawer 11 is pulled out a predetermined degree. When the drawer 11 is stopped, the first sliding portion 110 is located at the chute portion 121, as shown in fig. 5. Thus, the maximum movement stroke of the drawer 11 in the pull-out direction (illustrated as the y-direction) is limited by the stopper structure 125, and the drawer 11 is prevented from being completely pulled out of the storage chamber 10.

For example, the predetermined degree may be determined according to the length of the chamfer portion 121 in the y direction.

In one embodiment, the side wall of the drawer 11 may be provided with a stop portion 112, and the stop portion 112 is adapted to cooperate with the stop structure 125 to achieve the effect of stopping the drawer 11.

For example, the stop structure 125 can be an arc-shaped structure protruding in the z-direction, and the stop portion 112 can be an arc-shaped notch adapted to stop the drawer 11 when the drawer 11 moves in the y-direction until the stop portion 112 abuts against the stop structure 125.

In one embodiment, when the drawer 11 is stopped, the first slide 110 abuts the upper slot wall 124 of the chute portion 121 and the drawer 11 is supported by the second slide 126 in front of the chute portion 121.

For example, the second sliding portion 126 may include a second roller 127, and the side wall of the drawer 11 may be relatively provided with a support to support the movement of the second roller 127 during being pulled out or pushed back to the storage chamber 10, so as to reduce friction and optimize the moving effect of the drawer 11.

The curvature of the outer contour of the second roller 127 can be matched with the shape of the stop structure 125, and the stop portion 112 of the drawer 11 can be matched with at least one of the second roller 127 and the stop structure 125 to effectively achieve the stop effect.

The front end 12a of the guide rail 12 may be provided with a pivot portion 128, and the second roller 127 may be rotatably provided to the pivot portion 128.

The second roller 127 may be fixed to the rail 12 or located in front of the rail 12.

Thus, the front end 11a of the drawer 11 naturally sinks and the first slide portion 11 synchronously tilts back with the second slide portion 126 as a fulcrum. In this process, since the chute portion 121 is inclined in the pull-out direction toward the sink direction, the first slide portion 110 tilted in the reverse direction can be brought into abutment with the upper groove wall 124 of the chute portion 121 earlier. Further, the first sliding portion 110 and the inclined groove portion 121 which are abutted against each other can have an effect of preventing the front end 11a of the drawer 11 from further sinking. Further, since the first sliding member 110 is allowed to abut against the inclined groove portion 121 by a small stroke in the reverse tilting, the amount of sinking of the front end 11a of the drawer 11 can be effectively reduced.

In one embodiment, referring to fig. 5, in the drawing direction (shown as the y direction) of the drawer 11, a distance L1 from the boundary point of the chute portion 121 and the other portion of the chute 120 to the stop structure 125 is greater than a distance L2 from the first sliding portion 110 to the stop portion 112 of the drawer 11. Thus, the first sliding part 110 can be positioned in the chute part 121 when the drawer 11 is stopped, so as to reduce the sinking of the front end 11a of the drawer 11.

Specifically, the boundary point between the chute part 121 and the other part of the chute 120 may be a boundary point between the upper groove wall 120a of the chute 120 and the upper groove wall 124 of the chute part 121.

In one implementation, the chute portion 121 may be inclined in the pull-out direction (shown y-direction) toward the sinking direction at an inclination angle (shown inclination angle α) of 3 degrees to 10 degrees. The inclination angle α is an angle between the extending direction of the upper groove wall 124 of the inclined groove portion 121 and the y direction.

In one embodiment, the length of the chute portion 121 in the drawing direction (illustrated as the y direction) of the drawer 11 may be at least one third of the length of the chute 120 in the drawing direction (illustrated as the y direction) of the drawer 11.

From this, through the angle of declination of rational design chute part 121 and the length of chute part 121 for when realizing reducing the deflection effect, ensure that the user can not produce obvious pause and feel when pulling drawer 11, optimize user experience.

In one embodiment, the guide rail 12 may include an entrance section 129 located at a front end of the slide groove 120 in a drawing direction (shown as y-direction) of the drawer 11, the entrance section 129 being located in front of the chute portion 121. For example, the inlet section 129 may be closer to the front end 12a of the guide rail 12 than the chute portion 121.

In one embodiment, at least one of the upper or

lower slot walls

129a, 129b of the inlet section 129 is inclined in the direction of withdrawal of the drawer 11 (y-direction shown) progressively away from the other of said upper or

lower slot walls

129a, 129 b.

Thus, the inlet section 129 is in a bell mouth shape, which facilitates the first sliding part 110 of the drawer 11 to be installed in the sliding groove 120, and facilitates the assembly of the drawer 11.

For example, the upper slot wall 129a of the inlet section 129 may be formed by the upper slot wall 120a of the chute 120 and the lower slot wall 129b of the inlet section 129 may be formed by the lower slot wall 120b of the chute 120.

In one embodiment, the sliding slot 120 may include a horizontal section 130 behind the sliding slot 121 along the drawing direction (shown as y direction) of the drawer 11, and the lower slot wall 130b of the horizontal section 130 is parallel to the horizontal direction (e.g., y direction). Thus, the horizontal section 130 is adapted to support the drawer 11 to be pulled out or pushed back into the storage compartment 10 in a substantially horizontal direction, and to guide the drawer 11 to move to the chute part 121 when the drawer 11 is pulled out.

For example, the lower slot wall 130b of the horizontal segment 130 may be formed by the lower slot wall 120b of the chute 120.

In one embodiment, the rear end of the sliding chute 120 in the drawing direction (shown as y direction) of the drawer 11 may have an inclined portion 131, and the inclined portion 131 is inclined in the pushing-back direction (shown as opposite direction to the y direction) of the drawer 11 toward the sinking direction.

Thus, the drawer 11 pushed back to the inclined portion 131 along the slide groove 120 has a tendency to continue to automatically move into the storage chamber 10, so that the drawer 11 can automatically move to a final position after being pushed back to a predetermined degree.

For example, the inclined portion 131 may include a lower groove wall 131b, and the lower groove wall 131b of the inclined portion 131 may be formed by the lower groove wall 120b of the chute 120.

In one implementation, the chute 120 may include, in order along the y-direction, an inclined portion 131, a horizontal section 130, a chute portion 121, and an inlet section 129. Each part can comprise an upper groove wall and a lower groove wall which are opposite, the upper groove walls of the two adjacent parts are in smooth transition, and the lower groove walls of the two adjacent parts are also in smooth transition. The upper slot wall of each component is adapted to form an upper slot wall 120a of the chute 120 and the lower slot wall of each component is adapted to form a lower slot wall 120b of the chute 120.

Specifically, upper and

lower slot walls

129a, 129b of inlet section 129 extend in a direction away from each other in the y-direction to form a flare to facilitate extension of first runner 110 into runner 120.

The chute portion 121, which is located behind the inlet section 129 in the y-direction, may have an upper chute wall 124 extending obliquely downwards in the y-direction. Accordingly, the lower groove wall of the chamfer portion 121 may be parallel to the upper groove wall 124 thereof to ensure that the height of the chamfer portion 121 in the z-direction is substantially constant.

The horizontal segment 130, which is located rearward of the diagonal slot portion 121 in the y-direction, may have upper and lower slot walls 130b that each extend generally in the y-direction.

The inclined portion 131, which is located behind the horizontal section 130 in the y-direction, may have a lower groove wall 131b extending obliquely downward in the opposite direction to the y-direction. Accordingly, the upper groove wall of the inclined portion 131 may be parallel to the lower groove wall 131b thereof to ensure that the height of the inclined portion 131 in the z direction is substantially constant.

When the drawer 11 is positioned in the storage chamber 10, as shown in fig. 4, the first slide portion 110 is supported by the lower groove wall 131b of the inclined portion 131. While the drawer 11 is drawn out of the storage chamber 10 from the position shown in fig. 4, the first sliding part 110 slides along the lower groove wall 120b of the chute 120, and passes through the lower groove wall 131b of the inclined part 131 and the majority of the lower groove wall 130b of the horizontal section 130 in sequence.

When the drawer 11 is pulled out to the position close to fig. 5, the front end 11a of the drawer 11 sinks under the action of gravity, causing the first sliding part 110 to disengage from the lower groove wall 120b of the chute 120 and tilt up to abut against the upper groove wall 124 of the chute part 121.

As the drawer 11 is further pulled out, the stopper 112 of the drawer 11 abuts against the stopper 125 provided on the rail 12, and the drawer 11 is stopped, and the position of the drawer 11 is shown in fig. 5.

When the drawer 11 is pushed back into the storage compartment 10 from the position shown in fig. 5, the first slide 110 transitions from sliding along the upper slot wall 124 of the chute portion 121 to sliding along the lower slot wall 130b of the horizontal section 130.

As the drawer 11 continues to be pushed back, the first sliding portion 110 slides to the lower groove wall 131b of the inclined portion 131. At this time, even if the drawer 11 is not pushed in the direction opposite to the y direction, the first sliding portion 110 can continue to slide toward the rear end 12b of the guide rail 12 along the lower groove wall 131b of the inclined portion 131 by gravity. The drawer 11 can thus be automatically moved into the position shown in fig. 4.

In one embodiment, at least a portion of the travel of the first sliding member 110 in the inclined slot 121 contacts the upper slot wall 124 of the inclined slot 121, so that the rear end 11b of the drawer 11 is limited to tilt upwards, and further acts on the front end 11a of the drawer 11 to reduce the amount of sinking.

In view of the above, according to the present embodiment, the front end 12a of the guide rail 12 is provided with the inclined groove portion 121 inclined in the sinking direction of the drawer 11, so that it is possible to reduce the sinking amount of the front end 11a when the drawer 11 is pulled out. The reduction in the amount of sinking is advantageous in avoiding the front end 11a of the drawer 11 colliding with other components of the household appliance 1 (e.g., the drawer 11 located below in fig. 1) when the drawer 11 is pulled out.
