Description

Technical Field

[0001] The present invention relates to the technical field of washing machines, in particular to a washing machine suspension rod conversion device and a washing machine vibration absorber using the conversion device. Background Art

[0002] Existing pulsator washing machines generate vibrations during startup and operation. In order to reduce the vibrations, a washing machine hanging rod is directly installed between the washing machine outer drum and the washing machine outer shell. The washing machine hanging rod includes a washing machine vibration damper and an upper hanging rod installed together. The washing machine upper hanging rod is installed on the washing machine outer shell, and the washing machine vibration damper is installed at the bottom of the washing machine outer drum. Currently, there is no conversion device for connecting the washing machine hanging rod and the washing machine outer drum that is suitable for various models. In addition, due to the large size of the washing machine vibration damper, it can only be installed at the bottom of the washing machine outer drum, resulting in a single installation position of the washing machine hanging rod and weak correction ability.

[0003] Therefore, there is a need for a washing machine boom conversion device that solves the above-mentioned problem and a washing machine vibration absorber using the conversion device. Summary of the Invention

The device can be installed between the washing machine hanger rod and the washing machine outer drum, and can be used to modify existing washing machines. This solves the problem of the previous single installation position of the washing machine hanger rod. While not affecting the vibration damping capacity of the original washing machine guide rod, a secondary correction function is added, thereby increasing the correction capacity of the existing washing machine and making the operation of the existing washing machine more stable.

[0009] As a preferred technical solution, a limiting portion is provided on each of the limit blocks, and the limiting portion has a horizontally arranged limiting end face. The distance between the outer side of each of the limit end faces and the axis of the limit disk is greater than the radius of the bushing mounting hole. An installation guide portion is provided on the outer wall of each of the limit blocks, and the installation guide portion has a guide inclined surface inclined toward the axis of the limit disk.

[0010] As a preferred technical solution, the intermediate structure includes at least one group of connecting arms, each of the connecting arms includes an upper arm and a lower arm, each of the upper arms is integrated with the upper connecting member, each of the lower arms is integrated with the lower connecting member, and each corresponding upper arm and lower arm are fixedly installed together.

[0011] As a preferred technical solution, the upper connecting member includes a first upper horizontal connecting plate, which is bent to both sides to form a second upper horizontal connecting plate, and a swing angle limiting space for a shock absorber housing or a spring support is formed between the two second upper horizontal connecting plates. A downward-opening groove is provided at the bottom of the first upper horizontal connecting plate, and the groove is located above the swing angle limiting space. A through hole for a suspension rod is provided at the center of the groove.

[0012] As a preferred technical solution, the lower connecting member includes a first lower horizontal connecting plate, which is bent to both sides to form a second lower horizontal connecting plate. The second lower horizontal connecting plate is provided with a bushing mounting hole, and the independent hanger is installed in the bushing mounting hole through the bushing.

[0013] As a preferred technical solution, the upper suspension rod and the independent suspension rod are coaxially arranged.

[0014] As a preferred technical solution, the upper connecting member and the lower connecting member are symmetrically arranged along the independent suspension rod.

[0015] A washing machine vibration damper, the washing machine vibration damper is installed together with the upper suspension rod to form a washing machine suspension rod, including the washing machine suspension rod conversion device, the washing machine vibration damper includes a vibration damper shell or a spring upper support, the vibration damper shell or the spring upper support is installed in the swing angle limit space, the upper connecting member is installed with the washing machine vibration damper, the lower connecting member is installed with an independent suspension rod, the free end of the upper suspension rod is opposite to the free end of the independent suspension rod, one free end passes through the upper connecting member and is installed on the washing machine outer shell, and the other free end passes through the lower connecting member and is installed between the middle and bottom of the washing machine outer barrel.

[0016] By adopting the above technical solution, the beneficial effects of the present invention are:

[0017] Since the washing machine suspension rod conversion device and the washing machine vibration damper using the conversion device include an upper connecting part and a lower connecting part, the device is suitable for various models of washing machine vibration damping suspension rods and can be used to modify existing washing machines. The upper connecting part is connected to the washing machine vibration damper, and the independent suspension rod is installed between the middle and bottom of the washing machine outer barrel. Without affecting the original vibration damping capability of the washing machine guide rod, a secondary correction function is added, thereby increasing the correction capability of the existing washing machine and making the operation of the existing washing machine more stable.

[0018] Since the washing machine boom conversion device includes a swing angle limiting space, after this device is installed between the washing machine boom and the washing machine outer drum, during the use of the washing machine, when the washing machine outer drum shakes under the action of centrifugal force, the horizontal component of the washing machine boom will provide a first obstacle to the deflection of the washing machine outer drum. At the same time, the washing machine vibration damping device will swing in the swing angle limiting space, and the setting of the groove will hinder the swing of the shock absorber shell or the spring support, that is, this device will provide a second obstacle to the deflection of the washing machine outer drum. Therefore, this device not only does not affect the vibration reduction and correction of the washing machine outer drum by the washing machine guide rod, but also adds a secondary correction function, effectively improving the correction ability of the existing washing machine, reducing the shaking of the washing machine outer drum during operation, and ensuring the stability of the washing operation.

[0019] Since the washing machine hanger rod conversion device includes a vibration-damping activity space, after this device is assembled with the existing washing machine hanger rod, the upper hanger rod passes through the through hole, and the washing machine vibration isolator is arranged in the vibration-damping activity space. The connection method of the upper hanger rod and the upper connecting piece is more flexible, providing a moving gap for vibration-damping movement. At the same time, this method is fast to install and convenient for maintenance and replacement, and the setting of the vibration-damping activity space provides the vibration absorber with the displacement space required for vibration reduction.

[0020] Since the washing machine boom conversion device includes a bushing, the bushing limit block limits the bushing to the connecting arm, the bushing is constrained and installed in the bushing mounting hole, and the elastic clamping claw clamps the connecting arm, thereby fixing the upper connecting member and the connecting member through the bushing and the connecting arm. When the device is installed on an existing washing machine, the existing washing machine and the existing washing machine boom can be adapted by replacing the connecting arm of an appropriate length. If other models of washing machine booms are used, it is sufficient to replace the connecting arm without replacing the entire device. In the present invention, the setting of the bushing and the connecting arm improves the adaptability of the device.

[0021] After this device is installed together with the existing washing machine hanger, the independent hanger can be installed between the middle and bottom of the washing machine outer drum, which solves the problem of the single installation position of the existing washing machine hanger. The position of the washing machine hanger on the wall of the washing machine outer drum can be adjusted according to the size of different washing machine outer drums and the degree of operating swing, thereby improving the adaptability of the existing washing machine hanger and the corresponding washing machine outer drum, enabling the existing washing machine hanger to better reduce vibration and correct the deviation of the washing machine outer drum, thereby ensuring the stability of the washing machine operation.

The free end of the upper hanger 1 passes through the upper connecting member 3, and the free end of the independent hanger passes through the lower connecting member 4.

[0035] like Figure 2 and Figure 3 As shown together, the intermediate structure includes at least one group of connecting arms 7 , one end of each connecting arm 7 is fixedly mounted to the upper connecting member 3 , and the other end of each connecting arm 7 is fixedly mounted to the lower connecting member 4 .

[0036] Among them, a bushing mounting hole 8 is respectively provided at both ends of the upper connecting member 3 and the lower connecting member 4, and a bushing 9 is installed in each bushing mounting hole 8.

The groove 23 is located above the swing angle limiting space 22, and a suspension rod through-hole 24 is provided at the center of the groove 23.

[0039] Secondly, the lower connecting member 4 includes a first lower horizontal connecting plate 25, which is bent to both sides to form a second lower horizontal connecting plate 26. The second lower horizontal connecting plate 26 is provided with a bushing mounting hole 8, and the independent hanger 6 is installed in the bushing mounting hole 8 through a bushing 9.

[0040] The upper boom 1 and the independent boom 6 are coaxially arranged.

[0041] The upper connecting member 3 and the lower connecting member 4 are both symmetrically arranged along the independent suspension rod 6 .

[0042] A bushing limit block 27 is provided at both ends of each connecting arm 7 and at the end of the independent suspension rod 6 close to the lower connecting piece 4 , and a rubber pad 28 and a gasket 29 are provided between each limit plate 10 and the adjacent bushing limit block 27 .

[0043] In the first embodiment, the upper connecting member 3 and the lower connecting member 4 are fixedly connected by the connecting arm 7. Only by replacing the connecting arm 7 of different lengths, the washing machine boom conversion device can be adapted to washing machine vibration dampers 32 of different lengths, thereby improving the adaptability of the device to different washing machine vibration dampers 32 and making the upper connecting member 3 and the lower connecting member 4 reusable.

[0044] Example 2:

[0045] like Figure 4 As shown, this embodiment is basically the same as the first embodiment, except that the intermediate structure includes at least one group of connecting arms 7, each connecting arm 7 includes an upper arm 30 and a lower arm 31, each upper arm 30 is integrated with the upper connecting member 3, and each lower arm 31 is integrated with the lower connecting member 4, and each corresponding upper arm 30 and lower arm 31 are fixedly installed together. In the present invention, the upper arm 30 and the lower arm 31 are fixedly installed together by riveting or bolts. Compared with the first embodiment, the second embodiment can be quickly fixed together, has a simple structure, and is easy to operate.

[0046] Example 3:

[0047] like Figure 1 and Figure 5-Figure 7 As shown together, the washing machine vibration damper, the washing machine vibration damper 32 and the upper suspension rod 1 are installed together to form a washing machine suspension rod, and the washing machine suspension rod conversion device in Example 1 and Example 2 is applied.

[0048] The washing machine vibration absorber 32 includes a sealing structure, a friction structure, an unsealing structure, and a semi-open structure.

[0049] In the present invention, Figure 8As shown, according to the physical formula Fx=F×cos(α), F represents the magnitude of the pulling force exerted on the washing machine outer tub 2 by the washing machine hanger, Fx represents the horizontal component of F, and α represents the inclination angle between F and the horizontal plane. The larger the inclination angle α between F and the horizontal plane, the smaller cos(α), resulting in a smaller horizontal component Fx of F. The lower end of the washing machine hanger without the present device can only be installed at the bottom of the washing machine outer tub 2. Compared with the washing machine hanger without the present device, after the present device is installed in the existing washing machine, the washing machine vibration absorber 32 is connected to the upper connecting member 3, and the independent hanger 6 is installed between the middle and bottom of the washing machine outer tub 2, that is, the lower end of the existing washing machine hanger can be installed between the middle and bottom of the washing machine outer tub 2. After installing the present device, the angle between the existing washing machine hanger and the washing machine outer tub 2 is increased, that is, the inclination angle α between the washing machine hanger and the horizontal plane is reduced, thereby increasing the horizontal component of the force exerted by the washing machine hanger on the washing machine outer tub 2, thereby improving the deviation correction ability of the existing washing machine hanger on the washing machine outer tub 2, and making the washing machine operation more stable.

[0050] In summary, this device is compatible with various models of washing machine booms. This device can be installed between the washing machine boom and the outer drum of the washing machine to modify the existing washing machine, solving the problem of the previous single installation position of the washing machine boom. While not affecting the vibration reduction ability of the original washing machine guide rod, it adds a secondary correction function, increases the correction ability of the existing washing machine, and makes the operation of the existing washing machine more stable.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
