[0038] For ease of description, the up and down directions mentioned below are... Figure 4 Its vertical direction is consistent with the horizontal direction mentioned below. Figure 3 Its left-right direction is consistent, and the front-back direction mentioned below is consistent with it. Figure 3 Its vertical direction is consistent.

[0039] like Figures 1 to 4 As shown, a washing machine chassis 1 includes a first support base 101, a first telescopic member 102, a second support base 103, a second telescopic member 104, a third support base 105, a third telescopic member 106, a fourth support base 107, and a fourth telescopic member 108 connected end-to-end. The first support base 101, second support base 103, third support base 105, and fourth support base 107 collectively support the washing machine body 2, with the bottom of the washing machine body 2 abutting against these supports. The first telescopic member 102, second telescopic member 104, third telescopic member 106, and fourth telescopic member 108 can accommodate components such as an electric telescopic rod, a manual telescopic rod, a linear cylinder, and two mutually slidingly connected tubes. The first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 are arranged sequentially along the four vertices of a rectangular trajectory. The first support base 101 is located at the front left of the bottom of the washing machine body 2, the second support base 103 is located at the front right of the bottom of the washing machine body 2, the third support base 105 is located at the rear right of the bottom of the washing machine body 2, and the second support base 103 is located at the rear left of the bottom of the washing machine body 2. The extension and retraction directions of the first telescopic joint 102 and the third telescopic joint 106 are parallel to each other, as are the extension and retraction directions of the second telescopic joint 104 and the fourth telescopic joint 108. The extension and retraction directions of the first telescopic joint 102, the second telescopic joint 104, the third telescopic joint 106, and the fourth telescopic joint 108 are all horizontal.

[0040] The first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 are all L-shaped. The first support base 101 is connected to the second support base 103 via the first telescopic joint 102. The second support base 103 is connected to the third support base 105 via the second telescopic joint 104. The third support base 105 is connected to the fourth support base 107 via the third telescopic joint 106. The fourth support base 107 is connected to the first support base 101 via the fourth telescopic joint 108. Through the first telescopic joint 102, the second telescopic joint 104, the third telescopic joint 106, and the fourth telescopic joint 108, the first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 can move closer to or further away from each other, enabling the washing machine chassis 1 to be adjusted in both horizontal and longitudinal directions. This allows the washing machine chassis 1 to accommodate washing machine bodies 2 of different sizes, ensuring that the chassis 1 can support the washing machine body 2 even if the length and width of the washing machine body 2 are different.

[0041] The bottoms of the first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 are all equipped with foot cups 109. The foot cup 109 typically consists of a screw and a base plate, and is a commonly used mechanical component that adjusts the height of the equipment through the rotation of the screw, thereby adjusting the level of the washing machine base 1 and keeping the washing machine body 2 on the base 1 level. When the ground where the washing machine body 2 is located is tilted or uneven, adjusting the height of each foot cup 109 ensures that the washing machine body 2 remains level, preventing vibration and noise caused by tilting. The washing machine base 1 also allows for height adjustment of the washing machine body 2 above the ground, preventing it from getting damp due to water accumulation and avoiding friction and noise between the washing machine body 2 and the ground, thus preventing damage to the washing machine body 2.

[0042] The tops of the first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 are all equipped with shock absorbers 110. The bottom of the washing machine body 2 abuts against the shock absorber 110. The shock absorber 110 can use existing shock-absorbing components. The shock absorber 110 can use damping force to control the rebound of the spring and absorb the impact. The shock absorber 110 can absorb the vibration generated when the washing machine body 2 is working.

[0043] Furthermore, the shock absorber 110 includes a base 1101, a top seat 1102, a first folding assembly 1103, a second folding assembly 1104, and a cylindrical spring 1105; both the first folding assembly 1103 and the second folding assembly 1104 include an upper rotating plate 1106 hinged to the base 1101, a lower rotating plate 1107 hinged to the top seat 1102, a connecting shaft 1108, and a torsion spring 1109 sleeved on the connecting shaft 1108; the upper rotating plate 1106 and the lower rotating plate 1107 are hinged to each other via connecting shaft 1108. One end of torsion spring 1109 is connected to upper rotating plate 1106, and the other end of torsion spring 1109 is connected to lower rotating plate 1107. One end of cylindrical spring 1105 is connected to connecting shaft 1108 of first folding assembly 1103, and the other end of cylindrical spring 1105 is connected to connecting shaft 1108 on second folding assembly 1104. The axis of cylindrical spring 1105 is perpendicular to the axis of torsion spring 1109.

[0044] The base 1101 and the top seat 1102 are parallel to each other. The base 1101 is mounted on the first support seat 101, the second support seat 103, the third support seat 105, or the fourth support seat 107. The top seat 1102 is located above the base 1101 and is used to support the washing machine body 2. When the washing machine body 2 vibrates during operation, the top seat 1102 moves up and down in the vertical direction. The first folding assembly 1103 and the second folding assembly 1104 are folded by force, and the upper rotating plate 1106 and the lower rotating plate 1107 move closer to each other, causing the cylindrical spring 1105 and the torsion spring 1109 to deform. The cylindrical spring 1105 and the torsion spring 1109 absorb the vibration generated by the washing machine body 2 during operation. Specifically, when the upper rotating plate 1106 and the lower rotating plate 1107 rotate relative to each other around the connecting shaft 1108, they will twist the torsion spring 1109. The two ends of the torsion spring 1109 will generate forces of the same magnitude but opposite direction, resisting the rotation of the upper rotating plate 1106 and the lower rotating plate 1107. At this time, the torsion spring 1109 provides positive stiffness characteristics. The two ends of the cylindrical spring 1105 are fixedly connected to the connecting shaft 1108 of the first folding assembly 1103 and the connecting shaft 1108 of the second folding assembly 1104, respectively. The axis of the cylindrical spring 1105 is perpendicular to the axis of the torsion spring 1109. When the top seat 1102 approaches the base 1101, the upper end of the upper rotating plate 1106 rotates around the top seat 1102, and the lower end of the lower rotating plate 1107 rotates around the base 1101. Simultaneously, the upper rotating plate 1106 and the lower rotating plate 1107... 7. The components rotate and fold around the connecting shaft 1108. The folding directions of the first folding assembly 1103 and the second folding assembly 1104 are opposite, meaning that the connecting shafts 1108 of the first folding assembly 1103 and the second folding assembly 1104 will approach each other. The approaching connecting shafts 1108 will compress the cylindrical spring 1105, which will generate a force that resists the approaching of the connecting shafts 1108. At this time, the cylindrical spring 1105 provides negative stiffness characteristics. The torsion spring 1109 and the cylindrical spring 1105 together resist the folding of the first folding assembly 1103 and the second folding assembly 1104. The torsion spring 1109 and the cylindrical spring 1105 make the total stiffness zero, thus achieving the effect of shock absorption and vibration isolation.

[0045] Optionally, the shock absorber 110 also includes a damper 1110. The two ends of the damper 1110 are fixedly connected to the base 1101 and the top seat 1102, respectively. The damper 1110 is a rubber damper. When the top seat 1102 moves towards the base 1101, the damper 1110 is compressed, which slows down mechanical vibration and dissipates kinetic energy, enhancing the shock absorption and vibration isolation effect.

[0046] In one embodiment, the tops of the first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 are all provided with receiving grooves 111. The base 1101 is installed in the receiving grooves 111, and the initial height of the top seat 1102 is above the receiving grooves 111 to prevent the installation height of the washing machine body 2 from being too high. The width of the receiving groove 111 is greater than the width of the shock absorber 110 to avoid interference.

[0047] Optionally, the first support 101 is provided with a first enclosure 112, the second support 103 is provided with a second enclosure 113, the third support 105 is provided with a third enclosure 114, and the fourth support 107 is provided with a fourth enclosure 115. The first enclosure 112, the second enclosure 113, the third enclosure 114, and the fourth enclosure 115 are all L-shaped. The first enclosure 112, the second enclosure 113, the third enclosure 114, and the fourth enclosure 115 together form a clamping space for clamping the washing machine body 2. By utilizing the proximity of the first support base 101, the second support base 103, the third support base 105, and the fourth support base 107, the first enclosure 112, the second enclosure 113, the third enclosure 114, and the fourth enclosure 115 abut against the four sides of the washing machine body 2, so that the first enclosure 112, the second enclosure 113, the third enclosure 114, and the fourth enclosure 115 together clamp the washing machine body 2, thereby realizing the installation and positioning of the washing machine body 2.

[0048] Furthermore, the first enclosure 112, the second enclosure 113, the third enclosure 114, and the fourth enclosure 115 each include a first limiting plate and a second limiting plate connected by circular arcs; both the first limiting plate and the second limiting plate are provided with shock-absorbing pads 116, which are located in the clamping space. The shock-absorbing pads 116 can be silicone pads, sponge pads, etc., to reduce the impact force between the washing machine body 2 and the first enclosure 112, the second enclosure 113, the third enclosure 114, and the fourth enclosure 115 when the washing machine body 2 vibrates.

[0049] In one embodiment, the washing machine chassis 1 further includes a drain seat 117, a reversing seat 118 rotatably mounted on the drain seat 117, a fifth telescopic joint 119, a sixth telescopic joint 120, a seventh telescopic joint 121, and an eighth telescopic joint 122. The telescopic directions of the fifth telescopic joint 119, the sixth telescopic joint 120, the seventh telescopic joint 121, and the eighth telescopic joint 122 are parallel to each other, and their telescopic directions are all parallel to the telescopic direction of the first telescopic joint 102. The fifth telescopic joint 119, the sixth telescopic joint 120, the seventh telescopic joint 121, and the eighth telescopic joint 122 are respectively mounted on the first support seat 101, the second support seat 103, the third support seat 105, and the fourth support seat 107. Guide rails are provided on both sides of the drain seat 117, and sliders that are slidably connected to the guide rails are provided at the output ends of the fifth telescopic joint 119, the sixth telescopic joint 120, the seventh telescopic joint 121, and the eighth telescopic joint 122. The drain seat 117 is slidably connected to the first support seat 101 via the fifth telescopic joint 119, to the second support seat 103 via the sixth telescopic joint 120, to the third support seat 105 via the seventh telescopic joint 121, and to the fourth support seat 107 via the eighth telescopic joint 122. The height of the drain seat 117 is slightly lower than that of the first support seat 101, the second support seat 103, the third support seat 105, and the fourth support seat 107. In other embodiments, the drain seat 117 can also be connected to the first support seat 101, the second support seat 103, the third support seat 105, and the fourth support seat 107 via an elastic band.

[0050] The drain base 117 is provided with multiple drain channels 1171, which are arranged at intervals along the circumference of the reversing base 118. The reversing base 118 has a connecting channel 1181, which has an outlet and an inlet for connecting to the drain outlet at the bottom of the washing machine body 2. All drain channels 1171 are located on the rotation path of the outlet on the reversing base 118. By rotating the reversing base 118, the connecting channel 1181 connects to different drain channels 1171, thereby changing the drainage direction. This allows the washing machine body 2 to be installed with the drainage direction adjusted according to the location of the drain pipe on the ground, facilitating the installation of the drainage circuit.

[0051] Furthermore, the drain seat 117 is provided with multiple first scale lines, each corresponding to a single drain channel 1171. The reversing seat 118 is provided with second scale lines, and the multiple first scale lines are located on the rotation path of the second scale lines. By aligning the first and second scale lines, the reversing seat 118 can be rotated to adjust the drainage direction.

[0052] In one embodiment, the bottoms of the first support base 101, the second support base 103, the third support base 105, and the fourth support base 107 are all equipped with rollers 123 to facilitate the movement and handling of the washing machine chassis 1.

[0053] Meanwhile, this application embodiment also provides a washing device, including a washing machine body 2 and the aforementioned washing machine chassis 1. Specifically, the top seat 1102 of the shock absorber 110 is provided with an insertion hole 1111, and the support foot at the bottom of the washing machine body 2 can be inserted into the insertion hole 1111. The drain outlet of the washing machine body 2 is located on the bottom wall and communicates with the drum of the washing machine body 2. The drain outlet is connected to the connecting channel 1181 of the steering seat through a drain pipe.
