Description

Technical Field

[0001] The present application relates to the technical field of household appliances, and particularly relates to a shock absorption device and a laundry treatment device. Background Art

[0002] A drum - type laundry treatment device usually has a shock absorption system, which is used to buffer the vibration amplitude of the washing drum of the laundry treatment device during rotation. The shock absorption system usually includes suspension springs. When the washing drum is affected by external factors, the suspension springs will deform and release energy, thereby reducing the impact on the washing tub and the ground, and can also eliminate the noise during rotation and maintain the balance state inside the laundry treatment device. Different suspension angles of the suspension springs will affect the shock absorption effect of the shock absorption system. In the related art, the suspension angles of the suspension springs in the laundry treatment device are fixed, and the performance of the suspension springs cannot be changed by replacing the suspension angles. This may lead to poor shock absorption effect, and may cause the washing drum to vibrate greatly during operation, and even deviate seriously from the axis and impact the housing.

[0008] In some embodiments, the connecting plate is adjustably arranged in the front - to - back direction of the outer tub to adjust the distance between the connecting plate and the front end face of the outer tub.

[0009] In some embodiments, the line connecting the first end and the center of the first connecting portion is a first connecting line, and the first connecting line is inclined at a first angle with respect to the vertical direction, so that when the suspension spring connects the first connecting portion and the housing, the suspension spring is inclined at the first angle with respect to the vertical direction, and the range of the first angle is from 3 degrees to 9 degrees.

[0010] In some embodiments, at least three first connecting portions are provided on the connecting plate, and a plurality of first angles corresponding to the at least three first connecting portions increase in an arithmetic progression.

The mounting seat is detachably connected to the outer barrel, the positioning assembly is disposed between the mounting seat and the outer barrel, and the positioning assembly is used to position the mounting seat on the outer surface of the outer barrel.

[0012] In some embodiments, the shock absorption device includes a shock absorption assembly. The shock absorption assemblies are provided in one-to-one correspondence with the mounting seats. The shock absorption assembly includes a gas spring, a support leg, and a connecting seat. The connecting seat is mounted below the outer barrel.

In order for any person skilled in the art to implement and use the present application, the following description is given. In the following description, details are set forth for purposes of explanation. It should be understood that those of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, well-known structures and processes are not elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope that conforms to the principles and features disclosed in the present application.

[0030] An embodiment of the present application provides a shock-absorbing device and a laundry treatment device. The laundry treatment device can be a washing machine or others. The washing machine has a housing 4, an outer tub 5, and an inner tub. The inner tub is installed inside the outer tub 5, and the outer tub 5 is connected to the inner wall of the housing 4 through the shock-absorbing device.

[0031] On the one hand, as Figures 1 to 7As shown in the figure, an embodiment of the present application provides a shock absorption device, which includes a mounting seat 1 and a suspension spring 2; the mounting seat 1 is used to be mounted on the outer surface of the outer tub 5 of a laundry treatment device, and a plurality of spaced-apart first connection portions 12 are provided on the mounting seat 1; the suspension spring 2 has a relative first end 21 and a second end 22, the first end 21 is used to connect to the housing 4 of the laundry treatment device, and the second end 22 is detachably connected to one of the plurality of first connection portions 12 to adjust the mounting position of the suspension spring 2 on the mounting seat 1.

[0032] Among them, in the related art, there is a hanging hole on the surface of the outer tub 5 of the washing machine for connecting the suspension spring 2, and the mounting position of the suspension spring 2 cannot be changed. When the suspension spring 2 is used for a long time, the deformation of the suspension spring 2 will make the shock absorption effect worse, and the state of the outer tub 5 cannot be kept balanced. Therefore, only by replacing the suspension spring 2 with different performances can the shock absorption effect be changed, which consumes a high cost.

[0033] In the embodiment of the present application, the shock absorption device includes a mounting seat 1 mounted on the surface of the outer tub 5 of the washing machine, and a suspension spring 2 for connecting the mounting seat 1 and the housing 4. A plurality of first connection portions 12 are provided on the mounting seat 1, and the positions among the plurality of first connection portions 12 are different. The first end 21 of the suspension spring 2 is connected to the housing 4 of the washing machine, and the position of the first end 21 is fixed. The second end 22 of the suspension spring 2 can select one of the first connection portions 12 for connection. When the second end 22 of the suspension spring 2 is connected to different positions, the position of the outer tub 5 lifted by the suspension spring 2 in the housing 4 will change. With such a setting, when the outer tub 5 is installed in the housing 4, the position of the outer tub 5 can be adjusted by adjusting the mounting position of the suspension spring 2. The shock absorption effect and noise reduction effect of the suspension spring 2 are different at different positions. The decibel level of the noise generated by the washing machine when the suspension spring 2 is at different mounting positions can be counted to determine which mounting position of the suspension spring 2 has a better shock absorption effect and noise reduction effect. At the same time, the position of the outer tub 5 can be balanced by changing the mounting position of the suspension spring 2 to improve the anti-eccentric ability of the outer tub 5 and avoid collision between the outer tub 5 and the housing 4.

[0034] In some embodiments, a connecting plate 11 is provided on the mounting seat 1, and the connecting plate 11 extends toward the side away from the outer tub 5, and a plurality of first connection portions 12 are distributed on the connecting plate 11.

[0035] Specifically, the mounting seat 1 is in a plate-like structure, and the plate-like structure is arc-shaped and attached to the outer surface of the outer tub 5. A connecting plate 11 is provided on the side of the mounting seat 1 away from the outer tub 5, and the connecting plate 11 extends in the direction away from the outer tub 5. A plurality of first connection portions 12 are distributed on the connecting plate 11. Such a setting can set the first connection portions 12 to a position protruding from the outer tub 5, making the first connection portions 12 more obvious and facilitating the connection between the suspension spring 2 and the connecting plate 11 during assembly. In some other embodiments, a plurality of first connection portions 12 respectively protrude from the mounting seat 1.

[0036] In some embodiments, the first connecting portion 12 is a connecting hole penetrating through the connecting plate 11, and the connecting hole extends along the axial direction of the outer barrel 5.

[0037] Specifically, the orientation of the end face of the connecting plate 11 is the same as the extending direction of the axis of the outer barrel 5. Looking from the front side of the outer barrel 5, the end face of the connecting plate 11 can be directly seen. A plurality of connecting holes are provided through the end face of the connecting plate 11. The second end 22 of the suspension spring 2 is a hook structure, and the hook can conveniently hook any one of the connecting holes. With such a setting, since the connection between the hook and the connecting hole is convenient, it makes the replacement and installation position of the suspension spring 2 simpler. In some other embodiments, the connecting holes extend along the radial direction of the outer barrel 5.

[0038] In some embodiments, the connecting plate 11 is adjustably arranged along the front-back direction of the outer barrel 5 to adjust the distance between the connecting plate 11 and the front end face of the outer barrel 5.

[0039] Specifically, the position of the connecting plate 11 on the mounting base 1 can be adjusted. The distance between the end face of the connecting plate 11 close to the front side of the outer barrel 5 and the front end face of the outer barrel 5 is 60 mm, and the adjustable range of the connecting plate 11 is within 7 mm. That is, in this embodiment, the distance between the end face of the connecting plate 11 and the front end face of the outer barrel 5 can be 60, 61, 62, 63, 64, 65, 66 or 67 mm. The mounting base 1 and the connecting plate 11 are integrally formed. The mounting base 1 has multiple specifications, and the difference between multiple mounting bases 1 lies in the position of the connecting plate 11 on the mounting base 1. That is, on the outer barrel 5, one of the specifications of the mounting base 1 can be selected for installation to adapt to different sizes of the outer barrel 5. With such a setting, one mounting base 1 can be selected to make the center line of the connecting plate 11 coincide with the center line of the suspension spring 2 in the front-back direction, so that the suspension spring 2 will not be subjected to pulling forces in other directions, ensuring the normal use of the suspension spring 2. In some other embodiments, the connecting plate 11 is detachably mounted on the mounting base 1, and a plurality of adjustment holes are provided on the mounting base 1. The connecting plate 11 is mounted in one of the adjustment holes to adjust the position of the connecting plate 11.

[0040] In some embodiments, the connection line between the first end 21 and the center of the first connecting portion 12 is the first connection line, and the first connection line is inclined at a first included angle with respect to the vertical direction, so that when the suspension spring 2 connects the first connecting portion 12 and the housing 4, the suspension spring 2 is inclined at a first included angle with respect to the vertical direction. The range of the first included angle is from 3 degrees to 9 degrees.

[0041] Specifically, the center of the first connection part 12 from the position where the first end 21 of the suspension spring 2 is connected is the first connection line. That is, when the suspension spring 2 is connected to the connection hole, the first connection line is the hypotenuse of the first included angle, the position where the first end 21 of the suspension spring 2 is connected is the vertex of the first included angle, and the vertical direction is the right side of the first included angle. That is, the suspension spring 2 is connected to the first connection part 12 with a certain angle of outward swing relative to the vertical direction. The range of the first included angle can be 3, 4, 5, 6, 7, 8 or 9 degrees. In this embodiment, the first included angle is 3 degrees. The angles of the multiple first included angles of the multiple first connection parts 12 are different from each other. Such a setting can hang the suspension spring 2 on the first connection parts 12 at different angles, so as to test and obtain the best suspension angle.

[0042] In some embodiments, at least three first connection parts 12 are provided on the connection plate 11, and the multiple first included angles corresponding to the at least three first connection parts 12 increase arithmetically.

[0043] Specifically, the first included angle of the lowermost first connection part 12 is 3 degrees, the first included angle of the middle-position first connection part 12 is 6 degrees, and the first included angle of the upper-side first connection part 12 is 9 degrees. With such a setting, the difference between these angles is large, so that when adjusting the installation position of the suspension spring 2, a relatively obvious effect feedback can be obtained, and the difference in the shock absorption effect will not be insignificant due to too small a change in the angle. In some other embodiments, the multiple first included angles of the multiple first connection parts 12 increase geometrically.

[0044] In some embodiments, the shock absorption device includes a positioning component. The mounting seat 1 is detachably connected to the outer barrel 5. The positioning component is arranged between the mounting seat 1 and the outer barrel 5, and the positioning component is used to position the mounting seat 1 on the outer surface of the outer barrel 5.

[0045] Specifically, a plurality of threaded holes are provided on the outer barrel 5. The mounting seat 1 is provided with a plurality of through holes corresponding to the plurality of threaded holes. The through holes and the threaded holes are arranged in one-to-one correspondence. The through holes are used for a screw member to pass through, and the screw member is used to be screwed into the threaded hole. The positioning component includes at least two positioning pins. The two positioning pins are arranged on the surface of the outer barrel 5 at intervals. The mounting seat 1 is provided with positioning holes corresponding to the positioning pins, and the positioning pins are used to be inserted into the positioning holes. Such a setting facilitates the disassembly and assembly of the mounting seat 1. The screw member plus the positioning pins can limit the mounting seat 1. The plurality of screw members jointly fix the mounting seat 1, which can improve the mounting stability of the mounting seat 1.

[0046] In some embodiments, the shock absorption device includes a shock absorption component 3. The shock absorption component 3 is arranged in one-to-one correspondence with the mounting seat 1. The shock absorption component 3 includes a gas spring 31, a support leg 33 and a connection seat 32. The connection seat 32 is installed below the outer barrel 5. One end of the gas spring 31 is rotatably connected to the connection seat 32, and the other end is rotatably connected to the support leg 33. The support leg 33 is fixed to the inner wall of the housing 4.

[0047] Specifically, the number of shock-absorbing components 3 corresponds one-to-one with the number of mounting seats 1, and the number of suspension springs 2 corresponds one-to-one with the number of mounting seats 1. The expansion and contraction of the gas spring 31 is used to buffer the vibration on the outer barrel 5. When the outer barrel 5 rotates, the suspension spring 2 and the gas spring 31 act together to keep the outer barrel 5 balanced and not deviate from the central position, reducing the possibility of collision. At the same time, the gas spring 31 can also play a certain supporting role to support the outer barrel 5 and the inner barrel of the washing machine.

[0048] On the other hand, the embodiment of the present application provides a laundry treatment device, including a housing 4, an outer barrel 5, and the shock-absorbing device as described above. The housing 4 is provided with a receiving cavity, the outer barrel 5 is installed in the receiving cavity, and the shock-absorbing device is installed between the side wall of the receiving cavity and the outer barrel 5.

[0049] Specifically, the outer barrel 5 is installed in the housing 4, the shock-absorbing device is also provided in the receiving cavity, and the shock-absorbing device is provided between the side wall of the outer barrel 5 and the side wall of the receiving cavity for providing a shock-absorbing effect to the outer barrel 5. An upper connecting plate 41 is provided in the receiving cavity, the upper connecting plate 41 is fixed to the housing 4, and the first end 21 of the suspension spring 2 is hung on the upper connecting plate 41.

[0050] In some embodiments, the shock-absorbing device includes at least two mounting seats 1, and the two mounting seats 1 are spaced apart and installed on the outer surface of the outer barrel 5.

[0051] Specifically, in this embodiment, there are two mounting seats 1 and two suspension springs 2. The two mounting seats 1 are respectively arranged at the upper left corner and the upper right corner of the outer barrel 5, and the suspension springs 2 are correspondingly connected to the mounting seats 1. In the embodiment where the shock-absorbing component 3 is provided, correspondingly, two shock-absorbing components 3 are provided at the bottom of the outer barrel 5, and the two connecting seats 32 are respectively arranged at the lower left corner and the lower right corner of the outer barrel 5. The shock-absorbing effect is provided to the outer barrel 5 from four directions of the outer barrel 5, making the shock-absorbing effect better.

[0052] The above has introduced in detail the shock-absorbing device and the laundry treatment device provided by the embodiments of the present application. Specific examples are used in this article to elaborate on the principle and implementation manner of the present application. The description of the above embodiments is only used to help understand the method and its core idea of the present application; at the same time, for those skilled in the art, according to the idea of the present application, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present application.
