Description

CROSS-REFERENCE TO RELATED APPLICATIONS

The present application claims priority from Chinese patent applications No. 202210908304.2 , No. 202210910795.4 and No. 202210908305.7 filed on July 29, 2022 and entitled "CLOTHES TREATMENT APPARATUS", the entire disclosures of which are incorporated herein by reference.

FIELD OF THE INVENTION

The present application relates to the technical field of clothing treatment, and specifically provides a clothing treatment apparatus.

BACKGROUND OF THE INVENTION

In the prior art, there is a type of clothing treatment apparatus which is opened by pulling out. This type of clothing treatment apparatus uses a pull-out machine to put in laundry or other clothing and shoes for washing, drying or deodorizing, or take them out; it mainly includes an assembly of drawer and cabinet. The washing or other treatment of laundry is mainly completed inside the drawer, and the cabinet mainly plays a role of load-bearing and fixing. Therefore, the connection method between the drawer and the cabinet is particularly important.
In the prior art, the connection is mostly achieved through a sliding rail. However, for drawer washing devices similar to the pulsator type, since a washing tub is provided inside the drawer, there will be horizontal vibrations during the washing and spinning processes. The sliding rail is mainly designed to bear a vertical force, and has poor reliability in the horizontal direction. After a long time, the sliding rail will be damaged, making the drawer unable to be pulled out smoothly and ultimately completely damaged.
Accordingly, there is a need for a new clothing treatment apparatus in the art to solve the problem that the connection structure between the drawer and the cabinet in the prior art cannot effectively bear both horizontal and vertical forces.

They are only used for ease of description, and do not indicate or imply that the device or element must have a specific orientation, or must be constructed or operated in a specific orientation; therefore, they should not be considered as limitations to the present application. In addition, terms "first" and "second" are only used for descriptive purpose, and should not be understood as indicating or implying relative importance.
In addition, it should also be noted that in the description of the present application, unless otherwise clearly specified and defined, terms "install", "connect" and "connection" should be understood in a broad sense; for example, the connection may be a fixed connection, or a detachable connection, or an integral connection; it may be a mechanical connection, or an electrical connection; it may be a direct connection, or an indirect connection implemented through an intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present application can be interpreted according to specific situations.

First embodiment

Firstly, with reference to FIGS. 1-15, a specific preferred embodiment of the present application will be described.
Referring to FIGS. 1-15, the present application proposes a clothing treatment apparatus, which includes a first movement component, a second movement component, and a pull-out working component 3. The second movement component is provided with a groove 23. Specifically, in the first embodiment of the present application, the first movement component may be a rear roller 1, and the second movement component may be a sliding rail 2. In a possible embodiment, the solution of the sliding rail 2 may be the sliding rail 2 with protruding guide blocks 21 arranged on both sides and a slideway 22 arranged in the middle, as shown in FIGS. 2 and 11. Correspondingly, the groove 23 is arranged on a rear side of the slideway 22 to match with the first movement component.
The working component 3 can be a pull-out type pulsator washing machine, which can be directly slidably arranged on the sliding rail 2; alternatively, as shown in FIG. 2, the pulsator washing machine can be placed in a box (FIG. 2 only shows the box, and the body of the pulsator washing machine is not shown), and then slidably arranged on the sliding rail.
Next, reference is made to FIGS. 6, 7, and 8, a support component 31 is provided below the working component 3, and the rear roller 1 of the first movement component is also provided on the working component 3. In a preferred solution, the rear roller 1 is indirectly arranged on the working component 3 by placing it on the support component 31, as shown in FIG. 7.
Through the above structure, in the clothing treatment apparatus of the present application, the rear roller 1 can drive the working component 3 to move on the sliding rail 2 during the pulling process of the working component 3; after the working component 3 reaches a working position, the rear roller 1 moves to the groove 23, as shown in FIG. 9 or FIG. 10, so that the rear roller 1 does not support the gravity of the working component 3 or supports part of the gravity of the working component 3, and the support component 31 supports the remaining part of the gravity of the working component 3. There are two situations for this. If the rear roller 1 directly falls into the groove 23 completely and is suspended, at this time, the support component 31 will fully bear the gravity of the working component 3. If the rear roller 1 is provided with an elastic structure such as an elastic member like a spring arranged above the rear roller 1, as shown in FIG. 14, then the rear roller 1 can still provide certain support after abutting a bottom surface of the groove 23; at this time, the support component 31 plays a role in supporting the remaining part of the gravity of the working component 3.
In a preferred solution of the first embodiment, as shown in FIGS. 2, 6-8 and 11, support positions of the support component 31 in the above solution can be located on the protruding guide blocks 21 on both sides of the sliding rail 2, in which the support component 31 abuts against the protruding guide blocks 21 to transmit the force to the sliding rail 2. Of course, the support component 31 and the sliding rail 2 can also be staggered so that the force is directly transmitted to a bottom surface of a cabinet 7 (this solution is not shown in the drawings), or if the clothing treatment apparatus does not have the cabinet 7, the force can also be directly transmitted to the ground or an installation platform (this solution is not shown in the drawings).
Through the above structural design, the present application enables the rear roller 1 to fall into the groove 23 after the working component 3 is pulled out to put the clothing in and pushed back to the working position, so that the support component 31 supports the majority of the force, and the rear roller 1 no longer bears the eccentric force of the washing machine during the washing and vibrating process, that is, the rear roller 1 no longer bears the horizontal force, which is in turn borne by the support component 31. In this way, the service life of the rear roller 1 can be greatly extended. Moreover, due to the presence of the support component 31, the washing machine can also be supported more stably and firmly during the washing process, thus reducing the vibration frequency of the washing machine and reducing the overall vibration noise of the clothing treatment apparatus. Preferably, the support component 31 is a support block shown in FIG. 7; a bottom surface of the support block can be configured as a surface with a higher coefficient of friction, or the support block is overall made of a material with higher friction, such as rubber, further preventing the support component 31 from slipping or vibrating and displacing.
Preferably, in the first embodiment, as shown in FIG. 6, the clothing treatment apparatus of the present application is further provided with a front roller 4, which is arranged on a front side of the working component 3 and which is arranged to be capable of contacting with the ground to achieve support at a front end during the pulling process. Therefore, the overall structure does not rely entirely on the sliding rail to complete, and part of the force can be distributed to the front roller 4.
In the first embodiment, as shown in FIGS. 8 and 14, a damping device 5 is also provided on a rear side of the rear roller 1. The damping device 5 is preferably a spring; of course, it can also adopt other damping structures, such as a damping rod or an elastic block, so as to avoid excessive force after pushing in, which may cause the rear roller 1 to detach from the groove and continue to move backward and collide with the cabinet 7.
In the first embodiment, as shown in FIG. 14, a sensor 6 capable of detecting whether the rear roller 1 has stopped in place is also provided on an inner side of the groove 23. Preferably, the structure that can be extended and retracted up and down of the rear roller 1 can not only provide part of support force as described above, but also can prevent the rear roller 1 from being suspended, so that the rear roller 1 at least partially abuts against the sensor 6, avoiding failure of detection of the sensor 6 and improving the detection accuracy of the sensor 6. The steps of clothing treatment are started after the clothing treatment apparatus detects that the working component 3 is installed in place, so as to avoid accidental situations.
In the first embodiment, as shown in FIG. 15, the working component 3 is also provided with an insertable buckle 32, and the clothing treatment apparatus further includes a cabinet 7 on which a slot 71 that matches with the buckle 32 is provided. The buckle 32 is arranged such that it can move toward the slot 71 during the process of the working component 3 entering the working position, and can be inserted into the slot 71 after the working component 3 enters the working position. This insertion snap-fit connection solution is highly suitable for the solution of the present application, so that once the working component 3 is pushed into the working position in the present application, it can be locked; the function of unlocking first is achieved during the process of pulling out the handle, and the pushing and pulling action is also coordinated with the opening and closing of the lock. Users only need one action to achieve the opening and pulling-out actions, as well as closing and pushing-in actions.
In the first embodiment, as shown in FIG. 9, the sliding rail 2 can be parallel to the horizontal plane. At this time, after the working component 3 is pushed in, a certain inclination may be formed since the rear roller 1 has entered the groove 23; but this is also within the allowable range of the working state of the working component 3 of the present application, and it can still work normally.

Second embodiment

The solution of the second embodiment is overall the same as the first embodiment with the following difference therebetween: at the same time of achieving stable support for the working component 3 as in the first embodiment, horizontal placement of the working component 3 is also achieved; as shown in FIG. 10, in a more preferred embodiment, an operating side of the clothing treatment apparatus is a front side, and there is a height difference between front and rear sides of the second movement component (the sliding rail 2). Preferably, a height of the rear side is higher than that of the front side. Through the design of the height difference, the working component 3 can have an appropriate climbing action during the pushing-in process; then after the rear roller 1 falls into the groove 23, the overall flatness of the working component 3 can be achieved, making the working state of the working component 3 more stable. The service life is longer, and it is less likely to splash washing water during the operation.

Third embodiment

Next, reference is made to FIGS. 16 and 17, the third embodiment differs from the first and second embodiments in that a climbing boss 24 is provided on the front side of the groove 23 on the sliding rail 2 in the third embodiment, and correspondingly, two platforms 25 are also provided on the protruding guide blocks 21. This design makes the sliding rail 2 still be overall horizontal. The horizontal sliding rail 2 is a standard part with a lower purchase price, and there is no need to fabricate it into an inclined non-standard part. At this time, the rear roller 1 first passes over the climbing boss 24, and then during the process of the rear roller 1 falling into the groove 23, the support component 31 directly falls onto the platforms 25. At this time, it can also ensure that the working component 3 is overall placed horizontally during the operation, while also saving the cost. Preferably, the sliding rail 2 and the climbing boss 24 can be fixedly connected separately, or integrally formed; the protruding guide blocks 21 and the platforms 25 can be fixedly connected separately, or integrally formed.

Fourth embodiment

In the first embodiment, there is still a certain deficiency in limiting the position of the front roller 4. In order to make up for this defect, the present application also proposes a fourth embodiment. Referring to FIG. 18, two protruding stoppers 26 are also provided on the front side of the protruding guide blocks 21. When the working component 3 reaches the working position, the front roller 4 can be clamped between the two protruding stoppers 26, so that the front roller 4 no longer has a swinging state, and the overall clothing treatment apparatus is fixed more firmly. Preferably, as shown in FIG. 18, the protruding stoppers 26 are integrally formed with the protruding guide blocks 21, that is, the protruding stoppers 26 are protruding parts of the protruding guide blocks 21.

Fifth embodiment

As shown in FIGS. 19 and 20, in some extreme situations, such as when the user pulls the working component 3 vertically upward instead of pulling it horizontally, it is very likely to cause the sliding rail 2 to detach from the rear roller 4, resulting in the inability to slide and making the product fail to continue its operation. In order to avoid such extreme situations, in a fifth embodiment of the present application which is based on the first embodiment, anti-detachment concave rails 211 are designed on inner side walls of the protruding guide blocks 21. Two ends of the support component 31 are inserted into the anti-detachment concave rails 211. When the rear roller 4 moves to the groove 23, the support component 31 can bear the remaining part of the gravity of the working component. At this time, as shown in FIG. 17, there may be two situations. In one situation, the farthest distance M between the support component 31 and a lower side wall of the anti-detachment concave rail 211 after the support component 31 is inserted into the anti-detachment concave rails 211 is smaller than the farthest distance N between the support component 31 and a top surface of the protruding guide block 21 after the support component 31 is inserted into the anti-detachment concave rails 211, that is, M<N; at this time, the support component 31 at M abuts against the lower side walls of the anti-detachment concave rails to provide support force. If M>N, the support component 31 at N provides the support force. If M=N, the support component 31 at both M and N provides the support force. Due to the presence of the gap M, the rear roller 4 can also fall into the groove 23 normally without being affected, so that the anti-detachment concave rails 211 only play a role in preventing detachment and do not affect the actual operating trajectory of the product.
In summary, through the design of the support component 31 in combination with the groove 23, the present application enables the rear roller 1 to enter the groove 23 when the working component moves to the working position, and then the support component 31 plays the main supporting role. The supporting method of the rolling friction between the rear roller 1 and the slideway 22 is directly changed to the supporting method of the up-and-down stacking between the support component 31 and the protruding guide blocks 21. When the clothing is taken out after use, the working component 3 can be pulled out with a slight force, and the rear roller 1 can climb out of the groove 23 so that the rolling friction is restored, making it still very effortless for the user to push and pull. This seamless switching not only protects the rear roller 1 and reduces the noise generated by the working component 3 during operation, but also takes care of users, making it still very effortless for the user to push and pull. By making simple structural modifications to simply add the structures of the support component 31 and the groove, a fundamental switch and change in the movement mode is made on the basis of the original solution, which greatly improves the stability of the product on the basis of not increasing the cost of the clothing treatment apparatus of the present application, that is, the service life of the rear roller 1 is extended, and user satisfaction is also improved, meaning lower vibration noise during use. In addition, the present application also proposes a design of height difference between the front and rear sides of the sliding rail 2, which further improves the stability of product during use and also reduces the probability of water leakage and the like caused by the tilting of the working component 3. The design of the sensor 6 also ensures that washing, drying and other operations can be performed only after the working component 3 reaches the working position, ensuring the safety of the product.
