[0029] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0030] The present invention provides a washing machine support and shock absorption system, which is aimed at a buffer mechanism in a pulsator washing machine, wherein a spring is a main buffer structure. The present invention can not only timely adjust the corresponding buffer resistance according to the actual weight of the washing outer tub, but also effectively keep the reserved space between the washing outer tub and the washing machine body constant, which is beneficial to reducing the external volume of the washing machine body. In other words, for a 5-kilogram washing tub, its originally adapted buffer mechanism needs to occupy one unit of the reserved space between the washing outer tub and the washing machine body, and a 10-kilogram washing tub needs to occupy two units of the reserved space between the washing outer tub and the washing machine body. In the present invention, both a 5-kilogram washing tub and a 10-kilogram washing tub only need to occupy one unit of the reserved space between the washing outer tub and the washing machine body, thereby relatively reducing the external size of the washing machine, because the present invention does not need to change the spring stiffness coefficient or the reserved stroke of the buffer on a large scale.

[0031] See also Figure 1-6The embodiment of the present invention provides a washing machine support and shock absorption system, comprising a washing machine housing 1 and a washing tub 2, wherein a support and buffer mechanism is provided between the washing machine housing 1 and the washing tub 2, and the support and buffer mechanism comprises:

[0032] A supporting assembly 3, comprising a supporting plate 3.1 located at the bottom of the washing outer tub 2, and a plurality of force changing units 3.2 in contact with the washing outer tub 2 are provided on the supporting plate 3.1;

[0033] The buffer assembly 4 comprises a plurality of accommodating structures 4.1 evenly distributed in the circumferential direction of the washing outer tub 2, each accommodating structure 4.1 being provided with a buffer unit 4.2 and an adjusting unit 4.3, wherein the adjusting unit 4.3 can automatically adjust the buffer resistance of the buffer unit 4.2 according to the force change of the force changing unit 3.2;

[0034] Specifically, the edge of the supporting plate 3.1 is vertically fixed to the washing machine housing 1, and the middle part of the supporting plate 3.1 has a through hole to facilitate the transmission connection between the output shaft of the washing outer tub 2 and the driving mechanism on the washing machine housing 1. The force changing unit 3.2 can receive the gravity change of the washing outer tub 2 in real time and undergo corresponding deformation. The buffer unit 4.2 will undergo corresponding elastic deformation when squeezed by the washing outer tub 2, and has an obstructive reaction force on the movement of the washing outer tub 2 during the deformation process, namely, buffer resistance. The adjustment unit 4.3 can adjust the buffer resistance of the buffer unit 4.2 according to the deformation state of the force changing unit 3.2, so as to adapt to the impact force of the current washing tub weight, so that the washing machine always maintains a good and stable state during use.

[0035] In another embodiment provided by the present invention, the force changing unit 3.2 includes a support cylinder 3.21 fixed to the support plate 3.1, each support cylinder 3.21 is evenly distributed in an annular shape on the support plate 3.1, and a piston unit 3.22 in contact with the washing outer barrel 2 is movably provided in the support cylinder 3.21, and a transmission fluid 3.23 is provided in the piston space 5 formed between the piston unit 3.22 and the inner bottom wall of the support cylinder 3.21, wherein the piston unit 3.22 includes a piston block 15 located in the support cylinder 3.21, and a piston block 15 is vertically fixed on the top of the piston block 15 to contact with the washing outer barrel 2. The piston rod 16 contacts the bottom of the washing tub 2, and the outer side of the piston rod 16 is movably sleeved with a limiting cylinder 17 fixed to the bottom of the washing outer tub 2. The piston block 15 is connected to the support cylinder 3.21 by a first spring 18, which is conducive to the reset of the piston block 15. In actual use, when the weight of the washing outer tub 2 increases, the piston block 15 moves toward the bottom of the support cylinder 3.21, so that the transmission fluid 3.23 in the piston space 5 is squeezed and the pressure increases. According to the different gravity of the washing outer tub 2, the depth of the piston rod 16 extending into the limiting cylinder 17 is different.

[0036] In another embodiment provided by the present invention, the buffer unit 4.2 includes a buffer column 4.21 capable of contacting the washing outer tub 2, one end of the buffer column 4.21 is connected to a return spring 4.22 located in the accommodating structure 4.1, the return spring 4.22 can be a coil spring, and the other end of the return spring 4.22 is connected to the adjustment unit 4.3, and the washing outer tub 2 can be elastically deformed by squeezing the return spring 4.22 through the buffer column 4.21;

[0037] The regulating unit 4.3 comprises a first piston plate 4.31 fixed to the end of the return spring 4.22, that is, the first piston plate 4.31 is located at the end of the return spring 4.22 away from the buffer column 4.21, a first space structure 6 is formed between the first piston plate 4.31 and the inner bottom wall of the accommodating structure 4.1, the first space structure 6 is connected to the piston space 5 through the liquid transfer pipe 7, a first blocking portion 6.1 for limiting the first piston plate 4.31 is provided in the first space structure 6, and the first space structure 6, the piston space 5 and the liquid transfer pipe 7 are all filled with transmission fluid 3.23;

[0038] In actual use, when the pressure in the piston space 5 increases, the transmission fluid 3.23 transmits the pressure to the first space structure 6 through the fluid transmission pipe 7. The increase in the pressure in the first space structure 6 causes the first piston plate 4.31 to push the return spring 4.22 to be compressed. At this time, the return spring 4.22 is in a pre-compression state from its original natural length state. According to the characteristics of the return spring 4.22 itself, the elastic resistance of the return spring 4.22 in the pre-compression state is higher than that of the return spring 4.22 in the original natural length state. In this state, the buffer unit 4.2 is in a state of high buffer resistance, completing the switching of increased buffer resistance, which is suitable for withstanding the inertial impact of the washing outer barrel 2 with a large impact force. At this time, the washing outer barrel 2 squeezes the return spring 4.22 in the pre-compression state through the buffer column 4.21, and the elastic resistance it encounters becomes larger, thereby having a good buffering and shock absorbing effect. In addition, according to the different gravity of the washing outer barrel 2, the degree of pre-compression of the return spring 4.22 is different each time.

[0039] In another embodiment provided by the present invention, a second piston plate 4.23 is fixed on the rod body of the buffer column 4.21 inserted into the accommodating structure 4.1, and the second piston plate 4.23 can be fixed with the return spring 4.22, so as to increase the force bearing area of ​​the connection between the return spring 4.22 and the buffer column 4.21, and a second space structure 8 for accommodating the return spring 4.22 is formed between the second piston plate 4.23 and the first piston plate 4.31, and an air flow pipe 9 which can communicate with the outside is provided in the middle of the second space structure 8. In actual use, when the buffer column 4.21 applies pressure to the return spring 4.22, the second piston plate 4.23 moves toward the first piston plate 4.31, and the second space structure 8 is compressed. In this process, the compressed air in the second space structure 8 also plays an auxiliary buffering role;

[0040] In another embodiment provided by the present invention, the airflow tube 9 can be replaced by a ventilation component 19, and the ventilation component 19 includes a first hard cylinder 19.1 whose bottom extends into the accommodating structure 4.1, wherein the accommodating structure 4.1 includes a columnar block 4.11, and a columnar cavity 4.12 for accommodating a buffer unit 4.2 and an adjustment unit 4.3 is provided in the columnar block 4.11, and the length direction of the columnar cavity 4.12 is parallel to the horizontal plane, and the columnar block 4.11 is fixed to the washing machine housing 1, that is, the first hard cylinder 19.1 is perpendicular to the length direction of the columnar block 4.11, and a second hard cylinder 19.2 is vertically fixed and penetrated on the cylinder body of the accommodating structure 4.1 of the first hard cylinder 19.1, and the second hard cylinder 19.2 is suitable for A movable blocking block 19.3 is provided, and the blocking block 19.3 is a cylindrical block. A piston sealing space is formed between the blocking block 19.3 and the bottom end of the second rigid cylinder 19.2. A long strip opening 19.7 facing the tube mouth of the first rigid cylinder 19.1 is opened on the cylinder body of the second rigid cylinder 19.2. The length direction line of the long strip opening 19.7 is parallel to the axis line of the second rigid cylinder 19.2. An extension rod 19.4 fixed to the blocking block 19.3 is movably inserted at the bottom end of the second rigid cylinder 19.2. The length direction of the extension rod 19.4 is parallel to the moving direction of the second piston plate 4.23, and the length direction of the extension rod 19.4 is parallel to the axis line of the second rigid cylinder 19.2. Preferably, the extension rod 19 The outer part of the extended end of the second rigid cylinder 19.4 is connected to the outer part of the bottom of the second rigid cylinder 19.2 through an elastic sealing shielding sleeve 19.5, ensuring that the piston sealing space has good sealing performance. Preferably, when the extension rod 19.4 is at the maximum extended position, the elastic sealing shielding sleeve 19.5 can have an elastic restoring force that allows the extension rod 19.4 to return to its initial position. A nozzle 19.6 connected to the piston sealing space is fixed at the bottom of the second rigid cylinder 19.2. The nozzle 19.6 is provided with a one-way valve that only allows the flow direction to flow to the nozzle 19.6 nozzle. The nozzle of the nozzle 19.6 is toward the inner top position of the cylindrical cavity 4.12, that is, toward the top position of the second space structure 8. A sealed storage barrel 20 is fixed on the columnar block 4.11, and lubricating oil is stored in the storage barrel 20. The lubricating oil is used to reduce the friction resistance between the second piston plate 4.23 and the inner wall of the columnar cavity 4.12. The storage barrel 20 is connected with the second hard cylinder 19.2 near the bottom of the cylinder through a guide tube 21 with a one-way valve. The lubricating oil can only flow from the storage barrel 20 to the piston sealing space in one direction. The columnar cavity 4.12 is located at the bottom of the second space structure 8. A gathering container 22 is fixed, and there is always lubricating oil in the gathering container 22, such as a collecting barrel. The container mouth of the gathering container 22 is located at the bottom of the second space structure 8. The bottom of the gathering container 22 is connected with the storage barrel 20 through a liquid transfer tube 23.

[0041] In actual use, when the second piston plate 4.23 moves toward the first piston plate 4.31, it is a positive movement; when the second piston plate 4.23 moves away from the first piston plate 4.31, it is a reverse movement; when the buffer column 4.21 is subjected to the axial extrusion force and moves toward the inside of the cylindrical cavity 4.12, the second piston plate 4.23 moves forward, and the pressure in the second space structure 8 increases, so that the blocking block 19.3 moves toward the bottom end of the second hard cylinder 19.2. At this time, the piston sealing space is reduced, so that the lubricating oil in the piston sealing space can be sprayed to the inner top position of the cylindrical cavity 4.12 through the nozzle of the nozzle 19.6, so that the lubricating oil slides and spreads along the cavity wall at the top of the cylindrical cavity 4.12, keeping the cavity wall of the cylindrical cavity 4.12 in a lubricated state, and a branch pipe can also be added to increase the position of the cavity wall of the cylindrical cavity 4.12 where the lubricating oil needs to be sprayed;

[0042] During the movement of the blocking block 19.3 toward the bottom end of the second hard cylinder 19.2, as the blocking block 19.3 moves, the actual air permeability length of the long strip opening 19.7 gradually increases, thereby increasing the air escape speed in the second space structure 8 of the cylindrical cavity 4.12; as the second piston plate 4.23 continues to move for a distance, it is axially squeezed with the protruding end of the extension rod 19.4, and at this time, the blocking block 19.3 moves toward the cylinder mouth end of the second hard cylinder 19.2, and the piston sealing space forms a negative pressure, thereby sucking the lubricating oil in the storage barrel 20 into the piston sealing space, and the negative pressure in the storage barrel 20 increases, so that the lubricating oil in the gathering container 22 is supplemented into the storage barrel 20 through the guide tube 23, so that the lubricating oil in the cylindrical cavity 4.12 is in a circulating lubrication state, and the cross-sectional contour line of the cylindrical cavity 4.12 is preferably circular, and at the same time, the blocking block 19.3 blocks the long strip opening 19.7;

[0043] When the axial extrusion force on the buffer column 4.21 is removed, the second piston plate 4.23 moves in the opposite direction under the elastic restoring force of the reset spring 4.22. Preferably, a one-way spring air valve 24 is fixed to the second piston plate 4.23. The unit air flow rate of the one-way spring air valve 24 in the open state is 4 times the maximum air flow rate of the ventilation component 19. When the second piston plate 4.23 moves forward, the one-way spring air valve 24 is in a closed state. When the second piston plate 4.23 moves reversely, when the negative pressure in the second space structure 8 is lower than the external air pressure, the one-way spring air valve 24 can be in an open state, thereby ensuring that the second piston plate 4.23 can quickly return to its initial state.

[0044] In another embodiment provided by the present invention, a convex filter screen cover 25 for filtering foreign matter is fixed to the top of the gathering container 22. The convex filter screen cover 25 can be optionally semi-spherical. A support spring 26 is provided between the bottom of the convex filter screen cover 25 and the gathering container 22, which is used to keep the top of the filter screen cover 25 slightly protruding from the wall of the cylindrical cavity 4.12. In actual use, when the second piston plate 4.23 contacts the convex filter screen cover 25, the convex filter screen cover 25 is squeezed and becomes concave, and the support spring 26 is squeezed and deformed. When the second piston plate 4.23 leaves the convex filter screen cover 25, the restoring force of the support spring 26 restores the convex filter screen cover 25 to its initial state. During the recovery process of the convex filter screen cover 25, it is helpful to bounce off foreign matter attached to the mesh body, thereby maintaining the filtering and blocking effect of the convex filter screen cover 25.

[0045] In another embodiment provided by the present invention, the first piston plate 4.31 includes a first cover plate 4.311 and a second cover plate 4.312, the first cover plate 4.311 and the second cover plate 4.312 are connected and buckled by an elastic sealing ring 4.313, and a cavity is formed between the first cover plate 4.311 and the second cover plate 4.312, wherein an opening 4.314 is provided on the outer side of the first cover plate 4.311 facing the first space structure 6, and an elastic sealing membrane 4.315 covering the opening 4.314 is fixed on the first cover plate 4.311;

[0046] In actual use, when the first piston plate 4.31 is squeezed and moved by the transmission fluid 3.23, the elastic sealing membrane 4.315 is recessed, and the pressure in the cavity formed between the first cover plate 4.311 and the second cover plate 4.312 increases, so that the elastic sealing ring 4.313 bulges outward, further increasing the sealing between the first piston plate 4.31 and the wall of the containing structure 4.1, preventing the transmission fluid 3.23 from entering the second space structure 8 from the first space structure 6.

[0047] In another embodiment provided by the present invention, a plurality of plug-in tubes 4.316 are fixed on the concave surface of the first cover plate 4.311, and each plug-in tube 4.316 is inserted with a plug rod 4.317 fixed to the concave surface of the second cover plate 4.312, thereby increasing the deformation resistance of the cavity formed between the first cover plate 4.311 and the second cover plate 4.312, and also facilitating the assembly of the first cover plate 4.311 and the second cover plate 4.312.

[0048] In another embodiment provided by the present invention, a driving unit 10 is provided at the inner bottom of the washing machine housing 1. The driving unit 10 can be selected as a driving motor. The axis centerline of the power output shaft of the driving motor is upward. The output shaft of the driving unit 10 is fixed with a rectangular sleeve 11. A plug post 12 is adapted to be inserted in the rectangular sleeve 11. The cross-sectional contour line of the plug post 12 is rectangular. The plug post 12 is fixed to a connecting shaft extending from the bottom of the washing outer tub 2, so that space is reserved for the vertical movement of the washing outer tub 2 during use. A stabilizing mechanism for keeping the washing outer tub 2 in the washing machine housing 1, such as a slide rail, is provided on the outside of the washing outer tub 2.

[0049] In another embodiment provided by the present invention, a plug-in port 13 adapted to the columnar block 4.11 is provided on the inner wall of the washing machine housing 1, and the plug-in port 13 is connected to the columnar block 4.11 through an elastic gasket 14, thereby playing an emergency buffering and protecting role for the axial impact force of the columnar block 4.11 caused by overload, which is beneficial to avoid the washing machine housing 1 from being broken.
