This application relates to the field of washing machine technologies, and in particular, to a laundry treatment apparatus.
A washing machine is a relatively common laundry treatment apparatus in our daily life. Whether it is an up-loaded washing machine or a front-loaded washing machine, a door plate of the washing machine is generally hinged to a door hole of a housing of the washing machine, and the door hole is uncovered after the door plate is generally turned by a specific angle. However, when in an open state, the door plate occupies a relatively large external space of the housing of the washing machine. A sufficient space needs to be reserved when the washing machine is installed and placed, to ensure that the door plate of the washing machine can be normally opened.
In the prior art, in some advanced washing machines, the door plate is embedded in the middle of a housing wall where the door hole is provided. By providing a cavity for the door plate to move in the housing wall, the door hole can be uncovered or covered when the door plate moves in the cavity.

With reference to the foregoing technical solutions, the beneficial effects of this application are analyzed as follows:
The laundry treatment apparatus provided in this application includes a housing, a door plate, and a driving mechanism. The housing is provided with a door hole, and the door plate is used for covering the door hole. The driving mechanism is disposed on the housing and is in transmission connection with the door plate, and is used for driving the door plate to approach or move away from the door hole along a horizontal direction and approach or move away from the door hole along a vertical direction.

As shown in FIG. 1, an embodiment of this application provides a laundry treatment apparatus. The laundry treatment apparatus includes a housing 1, a door plate 2, and a driving mechanism 3. The housing 1 is provided with a door hole 11; the door plate 2 is used for covering the door hole 11; and the driving mechanism 3 is disposed on the housing 1 and is in transmission connection with the door plate 2, and is used for driving the door plate 2 to approach or move away from the door hole 11 along a horizontal direction L and approach or move away from the door hole 11 along a vertical direction H.
When the door hole 11 is uncovered, the door plate 2 first moves away from the door hole 11 along the horizontal direction L and then moves away from the door hole 11 along the vertical direction H; and when the door hole 11 is covered, the door plate 2 first approaches the door hole 11 along the vertical direction H and then approaches the door hole 11 along the horizontal direction L.
When the door hole 11 is uncovered, the laundry treatment apparatus first drives, by using the driving mechanism 3, the door plate 2 to move away from the door hole 11 along the horizontal direction L, and then drives, by using the driving mechanism 3, the door plate 2 to move away from the door hole 11 along the vertical direction H, so that a function of uncovering the door hole 11 can be implemented. Moreover, in this case, the door plate 2 is located at an interval on an outer side of the housing of the laundry treatment apparatus in parallel and occupy a relatively small external space when being opened. When the door hole 11 is covered, the laundry treatment apparatus first drives, by using the driving mechanism 3, the door plate 2 to approach to be right in front of the door hole 11 along the vertical direction H, and then drives, by using the driving mechanism 3, the door plate 2 to approach to be attached to the door hole 11 along the horizontal direction L, so that the door plate 2 covers the door hole 11. Moreover, in this case, because the door plate 2 is attached to the outer side of the housing of the laundry treatment apparatus, a housing structure of the laundry treatment apparatus is not affected at all.
Based on the foregoing, the laundry treatment apparatus provided in this application has advantages that the door plate 2 occupies a small external space when the door hole 11 is uncovered, and the door plate 2 does not affect the housing structure.
Specifically, the laundry treatment apparatus may be an apparatus such as a washing machine, a drying machine, or a dryer.
In an optional solution of this embodiment, the driving mechanism 3 includes a first driving member 31 and a second driving member 32. One end of the first driving member 31 is connected to a side of the door plate 2 facing the door hole 11, and the other end is connected to the second driving member 32, for driving the door plate 2 to approach or move away from the door hole 11 along the horizontal direction L; and the second driving member 32 is used for driving the first driving member 31 to approach or move away from the door hole 11 along the vertical direction H.
Specifically, as shown in FIG. 4 or FIG. 5, the driving mechanism 3 is configured as the foregoing first driving member 31 and the second driving member 32, and the function of covering or uncovering the door hole 11 by the door plate 2 is implemented in a manner that the first driving member 31 drives the door plate 2 to approach or move away from the door hole 11 along the horizontal direction L and the second driving member 32 drives the first driving member 31 to approach or move away from the door hole 11 along the vertical direction H, thereby achieving advantages of a simple structure and good driving stability.
In an optional solution of this embodiment, the first driving member 31 is an electric telescopic frame, and the second driving member 32 is a lifting motor. The lifting motor includes a lead screw rotating shaft 321 and a nut 322 sleeved on the lead screw rotating shaft 321. One end of the electric telescopic frame is connected to one side of the door plate 2 facing the door hole 11, and the other end is connected to the nut 322.
Specifically, as shown in FIG. 4, the first driving member 31 is configured as an electric telescopic frame, and the second driving member 32 is configured as a lifting motor. By electric telescoping of the electric telescopic frame along the horizontal direction L, the function of driving the door plate 2 to approach or move away from the door hole 11 along the horizontal direction L can be implemented. The lead screw rotating shaft 321 of the lifting motor rotates forward or backward to drive the nut 322 to move up or down along the vertical direction H, and further drive the electric telescopic frame to move up or down along the vertical direction H, so that a function of driving the door plate 2 to approach or move away from the door hole 11 along the vertical direction H is implemented. In addition, because the second driving member 32 is a main component for bearing the weight of the door plate 2, the lead screw rotating shaft 321 of the lifting motor may stably and reliably bear the door plate 2. In addition, the lifting motor may be configured as a stepper motor, and by controlling an output rotation angle of the lifting motor, a lifting height of the door plate 2 along the vertical direction H can be controlled stably and accurately.
The first driving member 31 is configured as the electric telescopic frame, and the second driving member 32 is configured as the lifting motor, thereby achieving advantages of a simple structure, driving stability, and good accuracy.
Certainly, both the first driving member 31 and the second driving member 32 may alternatively be configured as the foregoing electric telescopic frame, or the foregoing lifting motor.
In addition, this embodiment further provides another optional solution of the first driving member 31 and the second driving member 32. The first driving member 31 is an electric telescopic rod, and the second driving member 32 is a lifting motor. The lifting motor includes a lifting rack 323 and a gear 324 in meshing transmission with the lifting rack 323. One end of the electric telescopic rod is connected to a side of the door plate 2 facing the door hole 11, and the other end is connected to the lifting rack 323.
Specifically, as shown in FIG. 5, the first driving member 31 is configured as an electric telescopic rod, and the second driving member 32 is configured as a lifting motor. By electric telescoping of the electric telescopic rod along the horizontal direction L, the function of driving the door plate 2 to approach or move away from the door hole 11 along the horizontal direction L can be implemented. The gear 324 of the lifting motor rotates backward to drive the lifting rack 323 to move up or down along the vertical direction H, and further drive the electric telescopic frame to move up or down along the vertical direction H, so that a function of driving the door plate 2 to approach or move away from the door hole 11 along the vertical direction H can also be implemented. In addition, the lifting rack 323 can also bear the door plate 2 stably and reliably. The lifting motor is configured as a stepper motor, and by controlling an output rotation angle of the lifting motor, a lifting height of the door plate 2 along the vertical direction H is controlled stably and accurately.
The first driving member 31 is configured as the electric telescopic rod, and the second driving member 32 is configured as the lifting motor, thereby also achieving advantages of a simple structure, driving stability, and good accuracy.
Certainly, both the first driving member 31 and the second driving member 32 may alternatively be configured as the foregoing electric telescopic rod, or the foregoing lifting motor.
In an optional solution of this embodiment, on an outer side wall on which the door hole 11 is provided, the housing 1 is further provided with a recessed portion 12 for receiving the door plate 2. Along the vertical direction H, the housing 1 is further provided with a lifting seam 13 in the recessed portion 12, and the first driving member 31 penetrates the lifting seam 13 and is connected to a lower side of the door plate 2.
Specifically, as shown in FIG. 1, when the door plate 2 covers the door hole 11, the door plate 2 may be received in the recessed portion 12, thereby reducing the external space occupied when the door plate 2 covers the door hole 11. The lifting seam 13 vertically provided in the recessed portion 12 may receive and limit the first driving member 31, to prevent the first driving member 31 from shaking side to side along the horizontal direction. The first driving member 31 penetrates the lifting seam 13 and is connected to the lower side of the door plate 2. In this way, when the door plate 2 uncovers the door hole 11, the first driving member 31 first drives the door plate 2 to move away from the door hole 11 along the horizontal direction L, and the second driving member 32 then drives the door plate 2 to move upward along the vertical direction H, so that the door hole 11 is uncovered.
In addition, this embodiment further provides a second specific configuration solution of the door plate 2. On an outer side wall on which the door hole 11 is provided, the housing 1 is further provided with a recessed portion 12 for receiving the door plate 2. Along the vertical direction H, the housing 1 is further provided with a lifting seam 13 in the recessed portion 12, and the first driving member 31 penetrates the lifting seam 13 and is connected to an upper side of the door plate 2.
Specifically, as shown in FIG. 2, in this optional solution, the first driving member 31 penetrates the lifting seam 13 and is connected to the upper side of the door plate 2. In this way, when the door hole 11 is uncovered, the first driving member 31 first drives the door plate 2 to move away from the door hole 11 along the horizontal direction L, and the second driving member 32 then drives the door plate 2 to move downward along the vertical direction H, so that the door hole 11 is uncovered.
In addition, this embodiment further provides a third specific configuration solution of the door plate 2. On an outer side wall on which the door hole 11 is provided, the housing 1 is further provided with a recessed portion 12 for receiving the door plate 2. The door plate 2 includes a first door plate 21 and a second door plate 22. Along the vertical direction H, the housing 1 is further provided with a lifting seam 13 in the recessed portion 12, and the first driving member 31 penetrates the lifting seam 13 and is connected to a lower side of the first door plate 21 and an upper side of the second door plate 22 respectively.
Specifically, as shown in FIG. 3, in this optional solution, the door plate 2 is configured as the first door plate 21 and the second door plate 22, and the first driving member 31 is connected to the lower side of the first door plate 21 and the upper side of the second door plate 22 respectively. In this way, when the door hole 11 is uncovered, the first driving member 31 first drives the door plate 2 to move away from the door hole 11 along the horizontal direction L, and the second driving member 32 then separately drives the first door plate 21 to move upward along the vertical direction H, and drives the second door plate 22 to move downward along the vertical direction H, so that the door hole 11 is uncovered.
In an optional solution of this embodiment, a side of the door plate 2 facing the door hole 11 is further provided with a plugging portion 23 used for plugging the door hole 11; and when the door plate 2 covers the door hole 11, the plugging portion 23 is correspondingly plugged in the door hole 11.
Specifically, as shown in FIG. 4 and FIG. 5, the plugging portion 23 may be used for plugging and blocking the door hole 11 when the door plate 2 covers the door hole 11, to prevent moisture in the laundry treatment apparatus from wetting the door plate 2 through the door hole 11, and further improve a sealing effect of the door plate 2 for the door hole 11.
Certainly, to allow treatment inside the housing of the laundry treatment apparatus to be observed through the door hole 11, the door plate 2 and the plugging portion 23 may be preferably made of a transparent material, such as transparent plastic, or transparent tempered glass.
In an optional solution of this embodiment, along a direction toward the door hole 11, the plugging portion 23 is configured as a frustum with a gradually decreasing diameter.
Specifically, as shown in FIG. 4 and FIG. 5, the plugging portion 23 is configured as the frustum with the gradually decreasing diameter. In this way, when the plugging portion 23 plugs and blocks the door hole 11, even if the plugging portion 23 is not perfectly aligned with the door hole 11 and a slight deviation exists, the plugging portion 23 in the shape of the frustum may be also plugged in the door hole 11, and when the plugging portion 23 in the shape of the frustum is fully plugged in the door hole 11, beneficial effects of adjusting and calibrating a relative position relationship between the door hole 11 and the door plate 2 can further be achieved.
In an optional solution of this embodiment, the plugging portion 23 includes an annular peripheral wall abutting against the door hole 11, and a sealing member 231 is further disposed around the annular peripheral wall.
Specifically, as shown in FIG. 4 and FIG. 5, the sealing member 231 may be specifically configured as an annular sealing strip, such as a rubber sealing ring or a silicone sealing ring, and is fixed, by a process such as pasting or hot pressing and hot stamping, to the annular peripheral wall of the plugging portion 23 which abuts against the door hole 11. The foregoing sealing member 231 can further improve sealing performance of the plugging portion 23 for plugging and blocking the door hole 11.
The foregoing descriptions are merely exemplary embodiments of this application, but are not intended to limit this application. Any modification, equivalent replacement, improvement, or the like made without departing from the spirit and principle of this application shall fall within the protection scope of this application.
It should be noted that features of dependent claims may be combined with each other in any manner and combined with the features of independent claims without departing from the concept of this application.
