Description
Technical Field
The invention belongs to the field of washing machines, and particularly relates to a washing machine with a supporting damping piece.
Background
When the washing machine is operated in a dewatering starting mode, if the clothes are seriously loaded in a deviated way and the inner barrel rotates to be seriously eccentric, larger parallel amplitude can be generated, the inner barrel of the washing machine is possibly unbalanced in rotation, the barrel collision and abnormal vibration of the machine are generated, the washing machine can also shift in serious conditions, the washing machine is easily damaged, and even safety accidents are caused. Therefore, when the washing machine starts to operate in a dewatering mode, if the unbalance loading is serious, in order to prevent the outer barrel from seriously impacting the box body, a mode of installing a safety control rod and a stop switch below the washing machine tray seat is adopted. When the outer barrel rotates eccentrically, the outer barrel collides with the safety control rod to influence the stop switch, the washing machine stops running, then a dewatering program is restarted, or a wave wheel is adopted to run, the load distribution is adjusted, or partial water is compensated, the washing is carried out for a short time, the load distribution is balanced, and other modes are adopted.
In addition, a shock-absorbing supporter 3 is provided between the tub 1 and the cabinet 4 to achieve a shock-absorbing effect, as shown in fig. 1. Since the rotating eccentricity generated in the inner tub at the end where the supporting damper 3 is not provided is the largest at the initial starting stage of the washing machine, if the safety lever 5 is provided at a position on the tray base where it does not fit with the supporting damper 3, it is possible to trigger the safety lever 5 due to a large vibration at the initial starting stage of the dehydration, and then trigger the stop switch to suspend the washing machine. However, as the support damper 3 performs a damping function, the generated vibration is relatively reduced to meet the standard of the normal operation of the washing machine. Therefore, if the safety control lever 5 is triggered by a large vibration at the beginning of the dehydration start, the washing machine may not operate normally, and the user experience may be seriously affected.
The present invention has been made in view of this situation.

In some embodiments of the present invention, the washing tub assembly 200 includes a rotatable washing tub 203 and a water collecting device 204 installed outside the washing tub 203, and two supporting dampers are respectively connected to a bottom wall of the water collecting device 204; two suspension dampers are connected to the side walls of the water collecting device 204, respectively.

In the above solution, the wall of the washing tub 203 is not provided with dewatering holes, but is provided with a dewatering channel, so that water is guided into the water collecting device 204 and discharged through a water outlet arranged on the bottom wall of the water collecting device 204.
The proposal not only solves the problem of storing dirt and containing dirt between the barrels, but also achieves the purpose of capacity expansion. Also, for the capacity-expanded washing machine, the distance between the washing tub assembly 200 and the cabinet 100 becomes smaller than that of the conventional washing machine. The present invention adds a supporting shock absorbing member between the bottom of the water collecting device 204 of the washing machine and the cabinet 100, and can solve the problem that the washing tub assembly 200 collides with the cabinet 100 in the washing process. However, if the supporting dampers are provided at the four corners, an "over-constraint" condition occurs, and the vibration of the tub assembly 200 is easily transmitted to the cabinet 100 during the dehydration process, resulting in a displacement of the washing machine.
Therefore, the first supporting shock-absorbing member 401, the second supporting shock-absorbing member 402, the first suspension shock-absorbing member 501 and the second suspension shock-absorbing member 502 of the present invention are respectively located at four corners of the washing tub assembly 200 and the cabinet 100, and are arranged two by two at intervals, and the four members can jointly act on the washing tub assembly 200, thereby not only playing a role of common shock absorption, but also avoiding the washing machine displacement phenomenon caused by over-constraint problem.
In a further aspect, the upper edge of the water collecting device 204 does not exceed the centerline position of the washing tub 203 in the vertical direction; two suspension shock absorbers are respectively connected with the upper edge of the water collecting device 204.
In detail, the lower parts of the first suspension damper 501 and the second suspension damper 502 are respectively connected to the upper edge of the water collecting device 204, so that the occupied space of the suspension damper in the cabinet 100 can be reduced, and the capacity expansion of the washing machine can be facilitated.
In some embodiments of the present invention, the washing machine further includes a water inlet assembly communicating with the washing tub assembly 200, and the lever 300 is disposed at a side away from the water inlet assembly.
In the above scheme, the control rod 300 and the water inlet assembly are respectively arranged on two sides of the disk seat, so that the utilization rate of the space is maximized.
In a preferred embodiment, the lever 300 is disposed at the left rear of the washing machine, and it is understood that the left rear refers to the orientation when the user faces the washing machine.
In some embodiments of the present invention, the first and second suspension dampers 501 and 502 are inclined from the bottom to the top, from the inside to the outside; the first supporting shock-absorbing member 401 and the second supporting shock-absorbing member 402 are inclined from the outside to the inside from the bottom to the top.
In the above solution, the first and second suspension dampers 501 and 502 and the first and second support dampers 401 and 402 are obliquely disposed between the cabinet 100 and the washing tub assembly 200; so the steadiness is better, and the surplus of cushioning effect is bigger, not only can reduce the vibrations in vertical direction, also can play certain cushioning effect on other directions.
When the washing machine vibrates, the washing barrel assembly 200 deflects outwards, the distance from one end of the two shock absorption members connected with the box body 100 to the central axis of the washing machine is larger than the distance from one end of the shock absorption members connected with the washing barrel assembly 200 to the central axis of the washing machine, deformation or damping force can be generated along with the vibration of the washing machine to a greater extent, and the shock absorption effect is better. Since the vibration of the upper portion of the tub assembly 200 is greater than that of the lower portion, the first and second suspension dampers 501 and 502 are inclined from the inside to the outside from the bottom to the top, and the distance between the upper end and the tub assembly 200 is large, so that the tub assembly 200 is prevented from striking the hanger bar and can be more stably suspended on the upper portion of the cabinet 100.
Although the present invention has been described with reference to a preferred embodiment, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
