Reference will be made in detail to embodiments of the present disclosure. Examples of the embodiments are shown in the drawings. The same or similar elements and the elements having same or similar functions are denoted by like reference numerals throughout the descriptions. The embodiments described herein with reference to drawings are explanatory, illustrative, and used to generally understand the present disclosure. The embodiments shall not be construed to limit the present disclosure.
In the following, a front-loading washing machine according to embodiments of the present disclosure will be described with reference to
As shown in
The cabinet 100 has a front panel 110 (a front-and-back direction is indicated by an arrow B shown in
In the front-loading washing machine 1 according to the embodiments of the present disclosure, the tub 200 is configured to make the access port move up and down in the opening 111. Hence, compared with a front-loading washing machine having an access port disposed in a front surface in the related art, the washing machine 1 can make the access port move to a suitable position for a user to load clothes or unload them, for example, making the access port move upwards. The user does not need to stoop or crouch when loading clothes or unloading them. Therefore, not only ordinary users can conveniently add clothes or take clothes out via the access port, but also elderly people and other users who cannot stoop easily can load clothes or unload them successfully, which improves convenience of the washing machine 1.
Furthermore, as the access port may move up and down in the opening 111, the access port can be moved to a position for washing clothes after the clothes are added. For example, the access port can be moved downwards. When the clothes are washed, the drum can roll to drive the clothes to be beaten up and down so as to be washed, which not only reduces abrasion on the clothes, but also no longer needs to fully soak the clothes in water—instead, only needs a small amount of water for washing, thus reducing water consumption and facilitating environment protection.
In addition, the driving mechanism 400 is provided to drive the tub 200. The user can operate the driving mechanism 400 to drive the tub 200 when the user needs to adjust a position of the access port. The user can adjust a position of the tub 200 more effortlessly, to facilitate adjusting the position of the tub 200, so as to further improve convenience when the elderly people and similar users use the washing machine 1.
That is, in the washing machine 1, the tub 200 is configured to make the access port move up and down in the opening 111, and the driving mechanism 400 is provided to drive the tub 200 to move. In such a way, the washing machine 1 can not only achieve a washing effect as a common front-loading washing machine when washing clothes, but also adjust the access port to a suitable position for loading clothes or unloading them, which overcomes the problem that clothes cannot be conveniently loaded or unloaded from a front-loading washing machine in the related art, and hence makes it convenient for the user to use.
Accordingly, the front-loading washing machine 1 according to the embodiments of the present disclosure has the advantages of user-friendliness, little clothes abrasion, water saving and the like.
In the following, the front-loading washing machine 1 according to specific embodiments of the present disclosure will be described with reference to the drawings.
In some specific embodiments of the present disclosure, as shown in
The driving mechanism 400 drives the access port to move up and down between a non-washing position and a washing position in the opening 111. Thus, the driving mechanism 400 can be used for driving the tub 200 to make the access port move to the washing position so as to wash clothes, when the clothes needs washing; and the driving mechanism 400 can be used for driving the tub 200 to make the access port move to the non-washing position convenient for the user to add clothes or take clothes out, when the clothes does not need washing.
Specifically, as shown in
Specifically, as shown in
Advantageously, as shown in
Optionally, the access port has a motion scope in the opening 111 configured in such a way that an included angle between a central axis of the access port and a horizontal plane is 0 degree to 90 degrees. In other words, the access port can move between a first position where the central axis thereof lies horizontally and a second position where the central axis thereof stands vertically. Specifically, when the access port is located at the non-washing position suitable for loading clothes or unloading them, the central axis of the access port can be oriented along a vertical direction; and when the access port is located at the washing position suitable for washing the clothes, the central axis of the access port can be oriented along a horizontal direction. Thus, it is convenient for the user to load or unload the clothes from above and to wash the clothes through rolling of the drum.
Those skilled in the related art should understand that a motion standard of the access port can be adjusted according to actual needs. For example, when the access port is located at the non-washing position (as shown in
Accordingly, the washing machine 1 can adjust the height and positon of the access port, which eliminates the need to stoop to operate, and thus provides great convenience for the user and good user experience.
The washing machine 1 further includes a drain pump 510, a drain internal tube 520 and a drain external tube 530. Specifically, the drain pump 510 is mounted to the tub 200, the drain internal tube 520 is mounted to the tub 200 and connected with the drain pump 510, the drain external tube 530 is configured to be a flexible elastic tube, and the drain external tube 530 is connected with the drain pump 510 and extends out of the cabinet 100.
That is, the washing machine 1 further includes a drain assembly 500, and the drain assembly is mainly composed of the drain pump 510, the drain internal tube 520 and the drain external tube 530. As shown in
Optionally, the drain pump 510 is mounted to the tub 200 through a threaded fastener. The drain external tube 530 and the drain pump 510 are connected through a simple structure that is easy to mount and dismount, convenient to maintain and replace, and low in cost.
Under the action of the driving mechanism 400, the tub 200 of the washing machine 1 makes the access port of the washing machine 1 move up and down between the non-washing position and the washing position. During this process, the drain pump 510 and the drain internal tube 520 of the drain assembly 500 can move up and down synchronously with the tub 200 of the washing machine 1, and the drain assembly 500 can still work when the washing machine 1 starts washing.
Preferably, the drain external tube 530 may be made of a flexible and elastic material. As the drain external tube 530 itself is flexible and has a certain elasticity, the drain external tube 530 may have a certain elastic deformation in the washing machine 1 when the tub 200 of the washing machine 1 moves, which will not affect the movement of the tub 200 of the washing machine 1 and can also guarantee normal work of the drain assembly 500.
As the tub 200 is located at different angles during washing and static processes, the drain assembly 500 of the washing machine 1 will move up and down along with the tub 200 of the washing machine 1 compared with a front-loading washing machine in the related art. If a traditional mounting and fixing mode is adopted, the drain internal tube will be overlong, faults such as falling off, friction and snapping may easily occur, and the lower space of the washing machine cannot be utilized effectively.
Accordingly, in the front-loading washing machine 1 according to the embodiments of the present disclosure, by disposing the drain assembly 500 to the tub 200 of the washing machine 1 and making the drain assembly 500 move synchronously with the tub 200, a length of the drain internal tube 520 can be reduced, and the faults such as falling off, friction and snapping can be avoided. Further, by adopting a flexible and elastic tube as the drain external tube 530, faults such as falling off and snapping can be effectively avoided when the drain external tube 530 moves with the tub 200, and the reliability of the drain assembly 500 during movement can be improved.
Advantageously, according to an embodiment of the present disclosure, the drain internal tube 520 and the drain pump 510 are mounted to a bottom of the tub 200, such that a lower space below the tub 200 in the washing machine 1 can be effectively utilized, and the space use efficiency in the washing machine 1 can be raised. With reference to
In some specific embodiments of the present disclosure, the drain internal tube 520 is connected with the inlet of the drain pump 510 through an internal tube clamp hoop (not shown), and the drain external tube 530 is connected with the outlet of the drain pump 510 through an external tube clamp hoop (not shown).
Specifically, one end of the drain internal tube 520 is fitted over the inlet of the drain pump 510, and then the internal tube clamp hoop is disposed at an inlet position of the drain pump 510 to clamp the drain internal tube 520; in the same way, one end of the drain external tube 530 is fitted over the outlet of the drain pump 510, and then the external tube clamp hoop is disposed at an outlet position of the drain pump 510 to clamp the drain external tube 530. The reliability between the drain internal tube 520 and the inlet of the drain pump 510 and the reliability between the drain external tube 530 and the outlet of the drain pump 510 can be guaranteed, times of maintenance can be reduced, and the cost can be reduced. Moreover, the drain internal tube 520 and the drain external tube 530 can be prevented from falling off the drain pump 510, and normal draining of the washing machine 1 can be guaranteed.
