Description

Technical Field

[0001] The present invention relates to the field of household appliances, and in particular to a clothing processing device and a shock absorbing device thereof. Background Art

[0002] Washing machines are household appliances commonly used in families, and various types of washing machines have brought many conveniences to people's lives. With the continuous development of technology, washing machines have become increasingly large-capacity, and as washing machines gradually become larger, the overall size of washing machines will inevitably increase, so it is necessary to provide a small-volume, large-capacity washing machine; most existing washing machines use a suspension rod shock-absorbing structure to hang the water tub in the box. When the eccentricity in the rotating barrel is large, the water tub is easy to hit the box, and the vibration will be transmitted to the ground through the box during dehydration, resulting in large vibration noise in the pulsator washing machine during dehydration. In addition, when the water tub is connected to the upper side of the box through the suspension rod shock-absorbing structure, the vibration is transmitted to the casing, requiring the box to have sufficient strength to support the rotating structure, which increases the difficulty of designing and manufacturing the box.

[0003] The Chinese patent application number CN01261711.3 discloses a pulsator washing machine, in which a support component is installed between the bottom of the outer barrel and the bottom of the box, and is tilted and fixed relative to the horizontal and vertical directions. The support component is a push rod spring device, which consists of a push rod, a vibration damping cylinder, a spring, and upper and lower end covers. There are two springs, both of which are arranged in the vibration damping cylinder sealed by the upper and lower end covers. One end of the push rod extends into the vibration damping cylinder, and the end is connected to a baffle located between the two springs. One end is fixed to the outer barrel, and the other end is fixed to the bottom frame of the box, or the bottom platform of the box. This structure effectively constrains the outer barrel, so that the relative displacement between the outer barrel and the box is reduced whether the whole machine is in operation or transportation.

[0004] However, the assembly of the support components and the base in the above structure is very troublesome and takes a long time, and strict requirements must be placed on the assembly process. In addition, since the support components transfer the shock absorption to the base, and the base transfers it to the base foot, the base requires higher strength. Also, during the shock absorption process, the base vibrates with a large amplitude, causing the lines or pipes installed on the base to generate greater vibration noise.

[0005] In view of this, the present invention is proposed. Summary of the invention

[0006] In order to solve the above technical problems, an object of the present invention is to provide a shock absorbing device for clothing processing equipment which is simple and quick to install, has good shock absorbing transmission effect and strong stability.

[0007] Another aspect of the present invention provides a clothes processing device which is easy and quick to assemble and has low vibration and noise.

[0008] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0009] A shock absorbing device for a clothes processing device, comprising:

[0010] A supporting shock absorbing member, used for providing a shock absorbing damping force in a supporting direction;

[0011] A mounting seat, mounted on the lower end of the supporting shock absorbing member, connected with the supporting shock absorbing member to form an integrated assembly module;

[0012] The mounting seat is provided with at least two mounting positions, one mounting position is defined above the mounting seat for mounting the supporting shock absorbing member, and the other mounting position is defined below the mounting seat for mounting a supporting foot supporting the mounting seat.

[0013] According to the shock absorbing device of the clothing processing equipment embodiment of the present invention, since the supporting shock absorbing component and the mounting seat are connected to form an integrated assembly module, it can be used as a pre-installed unit to achieve integrated assembly, which can simplify the installation process, make the installation more convenient and stable, and improve the production efficiency. It can not only reduce the difficulty of installing the supporting shock absorbing component, but also avoid deformation caused by misalignment of the supporting shock absorbing component during installation, thereby reducing the shock absorbing effect and service life.

[0014] In addition, the supporting shock-absorbing member is connected to the supporting foot as a whole through the mounting seat, and the shock-absorbing force is directly transmitted to the supporting foot. The supporting stability is strong and the shock-absorbing effect is good, so that the outer barrel of the support shakes less and the clothing processing equipment is more stable.

[0015] In addition, the damping device for clothes processing equipment according to the above embodiment of the present invention may also have the following additional technical solutions:

[0016] According to one embodiment of the present invention, the mounting seat is provided with:

[0017] A first mounting position, recessed on one side of the mounting seat, forming a recessed portion for accommodating a lower end supporting component of the supporting shock absorbing member;

[0018] The second mounting position protrudes from the other side of the mounting seat to form a mounting column for mounting the supporting foot.

[0019] According to the shock-absorbing device of the clothing processing equipment embodiment of the present invention, the two mounting positions arranged above and below the mounting seat enable the supporting component supporting the lower end of the shock-absorbing component to be accommodated in the recessed portion on the upper side of the mounting seat, and the supporting foot is inserted into the protruding mounting column on the lower side of the mounting seat, which has greater stability and higher supporting strength.

[0020] Furthermore, the mounting seat comprises:

[0021] A concave sink groove, a part of which constitutes a recessed portion for accommodating the lower end supporting component of the supporting shock-absorbing member;

[0022] and a connecting portion extending from the opening of the sink to the outer periphery, for fixing the mounting seat;

[0023] The second installation position is arranged at the outer side of the bottom of another part of the sinking trough, and the other part of the sinking trough constitutes a movable space for the supporting leg to pass through the sinking trough.

[0024] The design of the above-mentioned mounting seat rationally utilizes the internal concave space of the sink and can reduce the overall height of the shock absorbing device through the upper and lower staggered layout, which not only improves the strength of the mounting seat, but also enhances the stability of the shock absorbing device and reduces the vibration noise caused by the shaking of the supporting shock absorbing parts.

[0025] Furthermore, the bottom of the sink is gradually inclined and becomes lower from the area where the activity space is located to the area where the recessed portion is located.

[0026] The inclined design of the above-mentioned groove bottom creates a spatial dislocation effect in height of the mounting seat, which can also reduce the overall height of the mounting seat and the installation space of the clothing processing base. In addition, it also enables the supporting shock-absorbing parts to be tilted to support and avoid structural damage caused by hard connection tilt.

[0027] Furthermore, the size of the area where the activity space in the sink is located is smaller than the size of the area where the recessed portion is located.

[0028] The mounting seat adopting the above structure has a small size, low cost and higher strength, and the base space of the clothing processing device used to support the mounting seat can be designed to be smaller, and the overall layout can be more reasonable.

[0029] Furthermore, the mounting seat is an integral sheet metal part or an integral injection molded part, which has high strength and is easy to process.

[0030] According to another embodiment of the present invention, the supporting shock absorbing member comprises:

[0031] A damper, one end of which is provided with an axially extending first mounting rod connected to the mounting seat;

[0032] The first mounting rod is provided with a first protruding step extending radially outward, the first protruding step is supported above the mounting seat, the end of the first mounting rod passes downward through the mounting seat, and the mounting seat is clamped between the first protruding step and the first fastener by cooperating with the first mounting rod under the mounting seat;

[0033] Preferably, a first buffer is sandwiched between the first protruding step and the mounting seat and / or between the first fastener and the mounting seat.

[0034] Furthermore, the shock absorbing device for the clothing processing equipment further comprises:

[0035] A connecting piece, mounted on the other end of the damper;

[0036] The other end of the damper is provided with a second mounting rod extending axially, the second mounting rod is provided with a second protruding step extending radially outward, the second protruding step is supported below the connecting member, the end of the second mounting rod passes through the connecting member upward, and the second fastener is connected to the second mounting rod above the connecting member to clamp the connecting member between the second protruding step and the second fastener;

[0037] Preferably, a second buffer member is sandwiched between the second protruding step and the connecting member and / or between the second fastener and the connecting member.

[0038] The above-mentioned embodiment of the present invention can utilize the compression amount of the buffer instead of the torque by setting the first buffer component and / or the second buffer component, so that the installation accuracy is higher, the transmission of the vibration force between different components can be properly buffered, and the torque error caused by lateral shaking can be prevented from causing adverse effects on vibration and noise.

[0039] Furthermore, the damper comprises:

[0040] Damping inner rod;

[0041] A damping outer cylinder, wherein the damping outer cylinder is movably sleeved on the damping inner rod along the axial direction of the damping inner rod;

[0042] One end of the damping outer cylinder away from the damping inner rod is connected to the mounting seat, or one end of the damping inner rod extending out of the damping outer cylinder is connected to the mounting seat;

[0043] Preferably, the supporting shock absorbing member further comprises:

[0044] The shock-absorbing elastic member is sleeved on the damping inner rod of the damper and is used for providing auxiliary damping force for the axial movement of the damping inner rod.

[0045] Compared with the method of using a damper alone for shock absorption, the structure of the supporting shock absorbing member can avoid the difficulty of speeding up the clothes processing device and ensure the washing efficiency. In other words, the supporting shock absorbing member can avoid the defects of using a single shock absorption method, ensure the stability of the outer barrel support, and reduce the noise of the clothes processing device during operation.

[0046] The present invention also provides a clothes processing device, comprising

[0047] A box body, comprising a base and a shell constituting the outer appearance of the laundry processing device, wherein the shell is mounted on the base;

[0048] An outer barrel is arranged in the box body;

[0049] Support feet, installed at the bottom of the box, used to support the box;

[0050] The above-mentioned shock-absorbing device for clothes processing equipment is arranged between the base and the outer barrel, the mounting seat is mounted on the base, and the supporting foot is mounted on the mounting position of the mounting seat below the base.

[0051] The clothing processing equipment adopts the shock-absorbing device described in the present invention to support the outer barrel above the base, which can greatly improve the constraint on the position of the outer barrel in the box, reduce the shaking and vibration amplitude of the outer barrel, and make the whole equipment achieve better shock-absorbing effect, thereby reducing the gap between the outer barrel and the box, so that the capacity can be increased by increasing the diameter and height of the outer barrel.

[0052] In addition, the lower end of the supporting shock-absorbing member is connected to the mounting seat support, and the mounting seat is fixedly supported on the base, which can not only improve the strength of the base, but also facilitate reducing the strength requirements of the box, and also make the supporting shock-absorbing member easier to install and more accurately positioned, thereby improving the balance of the outer barrel in the box.

[0053] By adopting the above structure, the mounting seat adopts a groove design, and the mounting seat can be embedded in the base, which can prevent the mounting seat from moving on the base. The mounting position of the support shock absorber is set in the groove, which can also improve the position stability of the support shock absorber on the mounting seat and prevent the support shock absorber from moving horizontally on the mounting seat and the base; in addition, the sinking design of the groove can not only effectively increase the shock-absorbing effect distance of the support shock absorber, but also enhance the strength of the mounting seat and avoid deformation of the mounting seat; the supporting foot and the supporting shock absorber are integrated on the mounting seat, and the supporting force borne by the supporting shock absorber can be effectively transmitted to the supporting foot, further improving the impact strength of the base, and transmitting the vibration to the ground through the supporting foot, thereby avoiding the noise caused by the vibration of the box.

DETAILED DESCRIPTION

[0065] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0066] In the description of the present invention, it should be noted that the terms "up", "down", "left", "right", "vertical", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0067] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0068] like Figure 1 and Figure 2 As shown, the present invention provides a shock absorbing device for a clothes processing device, comprising

[0069] A support shock absorbing member 32, used for providing a shock absorbing damping force in a supporting direction;

[0070] A mounting seat 4 is mounted on the lower end of the supporting shock absorbing member 32 and connected with the supporting shock absorbing member 32 to form an integrated assembly module;

[0071] The mounting seat 4 is provided with two mounting positions, namely a first mounting position 411 and a second mounting position 412. The first mounting position 411 is defined above the mounting seat 4 and is used to install the supporting shock absorbing member 32. The second mounting position 412 is defined below the mounting seat 4 and is used to install the supporting foot 5 supporting the mounting seat 4.

[0072] The mounting base of the present invention is provided with at least two mounting positions. The above only uses two mounting positions as an example, which does not limit the number of mounting positions of the present invention. For example, a mounting position for installing a support roller for moving a clothing processing device, or a mounting position for installing a support height adjustment device, etc. can also be provided.

[0073] In the above structure, the first mounting position 411 is designed to be concave on the upper side of the mounting seat 4, forming a concave portion for accommodating the lower end support component of the support and shock absorber 32. The concave accommodation design can not only play a guiding and positioning role in the installation of the support and shock absorber 32, but also enhance the strength of the mounting seat 4;

[0074] The second mounting position 412 protrudes from the other side of the mounting base 4 to form a mounting column for mounting the supporting foot 5 (see Figure 2 ), the screw of the supporting foot 5 is screwed into the mounting column, which can adjust the height of the supporting foot and adjust the balance of the clothing processing equipment on the ground. The protruding mounting column structure designed at the second mounting position 412 can enhance the connection strength between the supporting foot 5 and the mounting base 4.

[0075] In one embodiment of the present invention, the mounting seat 4 of the present invention comprises a sink 41 and a connecting portion 42, wherein the sink 41 is a concave design structure of the mounting seat 4, and the opening of the sink extends toward the periphery to form the connecting portion 42, wherein:

[0076] A part of the sink 41 forms a recessed portion for accommodating the lower end support component of the support and shock-absorbing member 32, that is, forming the first installation position 411;

[0077] The connecting portion 42 is provided with a connecting structure such as a screw hole 421, and the connecting portion 42 is supported on the base 12 of the laundry processing device. The mounting base 4 can be fixed on the base 12 by passing the screw 422 through the screw hole 421 (see Figure 1 , Figure 4 and Figure 7 );

[0078] The second mounting position 412 is arranged at the outer side of the bottom of another part of the sink 41, and the other part of the sink 41 constitutes a movable space for the support leg 5 to be inserted into the sink 41, that is, when the extension amount of the support leg 5 relative to the mounting column is adjusted to adjust the support height, the support leg 5 will pass through one end of the mounting column in the movable space (see Figure 2 ).

[0079] This design rationally utilizes the internal concave space of the sink and can reduce the overall height of the shock-absorbing device through an up-and-down staggered layout. It not only improves the strength of the mounting base, but also enhances the stability of the shock-absorbing device and reduces the vibration noise caused by the shaking of the supporting shock-absorbing parts.

[0080] Preferably, the center of the second installation position 412 and the center of the first installation position 411 are located in the same radial direction of the outer barrel 2 .

[0081] like Figure 7As shown, in the clothes processing device, the distance between the supporting foot 5 and the center of the outer tub 2 is greater than the distance between the lower end of the supporting shock absorbing member 32 and the center of the outer tub 2. Therefore, the distance between the second mounting position 412 of the present invention and the center of the outer tub 2 is farther than the distance between the first mounting position 411 and the center of the outer tub 2. In addition, since the mounting seat 4 is mounted on the four corners of the base 12, in order to facilitate and flexibly assemble, the size of the area where the activity space in the sink 41 is located can be designed to be smaller than the size of the area where the recessed portion is located (see FIG. Figure 1 ).

[0082] Furthermore, the bottom of the sink 41 gradually slopes down from the area where the activity space is located to the area where the recessed portion is located (see Figure 2 ).

[0083] The inclined design structure of the above-mentioned trough bottom creates a spatial dislocation effect in height of the mounting seat 4, and can also reduce the overall height of the mounting seat 4, reducing the installation space of the clothing processing base. In addition, it also enables the supporting shock-absorbing parts to be tilted to support, avoiding structural damage caused by hard connection tilt.

[0084] The mounting seat 4 of the present invention can be designed as an integral sheet metal part manufactured by a stamping process, or as an integral injection molded part manufactured by a high-strength plastic or rubber and metal injection molding process.

[0085] like Figure 2 As shown, the supporting shock absorbing member 32 of the present invention comprises:

[0086] The damper 321 has a first mounting rod 323 extending axially at one end and connected to the mounting seat 4;

[0087] The first mounting rod 323 is provided with a first protruding step 324 extending radially outward, the first protruding step 324 is supported in the first mounting position 411 of the recessed groove 41 above the mounting seat 4, the end of the first mounting rod 323 passes downward through the bottom of the recessed groove 41, and the mounting seat 4 is clamped between the first protruding step 324 and the first fastener 6 through the first fastener 6 below the mounting seat 4, and the first fastener 6 is preferably a tightening nut, which is screwed to the first mounting rod 323;

[0088] Preferably, a first buffer member 7 is sandwiched between the first protruding step 324 and the mounting seat 4 and / or between the first fastener 6 and the mounting seat 4 .

[0089] Furthermore, a groove bottom through-hole 413 is punched out at the groove bottom of the sink groove 41 corresponding to the first mounting position 411, and the groove bottom through-hole 413 is flanged downward to form a cylindrical structure. The first buffer member 7 includes a third buffer block 71, which is clamped between the first protruding step 324 and the groove bottom of the sink groove 41. The third buffer block 71 is provided with a protrusion on the side facing the groove bottom, and the protrusion extends into the groove bottom through-hole 413. By extending the protrusion into the groove bottom through-hole 413, the third buffer block 71 can be prevented from sliding in the sink groove 41, thereby achieving positioning and more convenient installation.

[0090] Furthermore, a third gasket 72 is provided between the first protruding step 324 and the third buffer block 71, which can not only improve the limiting effect of the first protruding step 324 and the groove 41 on the third buffer block 71, but also increase the force-bearing area of ​​the third buffer block 71 and increase the compression amount of the third buffer block 71, thereby further reducing vibration and noise. In addition, it can avoid damage to the third buffer block 71 due to concentrated force.

[0091] Preferably, below the mounting seat 4, a fourth gasket 73 is sandwiched between the end of the cylindrical structure corresponding to the downward-turned through hole 413 at the bottom of the groove and the first fastener 6 to prevent the locking stress and vibration force of the first fastener 6 from damaging and deforming the through hole 413 at the bottom of the groove.

[0092] like Figure 4 and Figure 5 As shown, in another embodiment of the present invention, the damping device of the laundry processing equipment further comprises:

[0093] A connecting member 22, mounted on the other end of the damper 321;

[0094] The other end of the damper 321 is provided with an axially extending second mounting rod 325, the second mounting rod 325 is provided with a second protruding step 326 extending radially outward, the second protruding step 326 is supported below the connecting member 22, the end of the second mounting rod 325 passes through the connecting member 22 upward, and the connecting member 22 is clamped between the second protruding step 326 and the second fastener 8 by the second fastener 8 above the connecting member 22, and the second fastener 8 is preferably a tightening nut, which is screwed to the second mounting rod 325;

[0095] Preferably, a second buffer member 9 is sandwiched between the second protruding step 326 and the connecting member 22 and / or between the second fastening member 8 and the connecting member 22 .

[0096] A further solution is that the second buffer component 9 includes a first buffer block 91 which is sleeved on the second mounting rod 325, and the side of the first buffer block 91 abutting against the connecting component 22 is a spherical supporting surface 911. The connecting component 22 is provided with a through mounting hole 221, and the end of the mounting hole 221 facing the spherical supporting surface is a spherical groove 222 which cooperates with the spherical supporting surface, and the spherical supporting surface 911 of the first buffer block 91 is supported in the spherical groove 222.

[0097] Preferably, the first buffer block 91 is provided with a through hole 912 for the second mounting rod 325 to pass through the spherical supporting surface 911, and the through hole 912 is arranged radially along the spherical supporting surface 911. A protruding side of the spherical supporting surface 911 is provided with a protruding sleeve 913 extending along the direction of the through hole 912. The sleeve 913 is also sleeved on the second mounting rod 325, and the sleeve 913 passes through the mounting hole 221 of the connecting member 22.

[0098] The second buffer member 9 further includes a second buffer block 92 . The second buffer block 92 is disposed on the other side of the connecting member 22 opposite to the spherical groove 222 and is sleeved on the outer circumference of the sleeve 913 .

[0099] More preferably, the spherical supporting surface 911 of the first buffer block 91 is arranged between the connecting member 22 and the second protruding step 326, the second buffer block 92 is arranged between the second fastener 8 and the connecting member 22, the second fastener 8 is a tightening nut, which is threadedly connected to the second mounting rod 325, and a second gasket 94 is arranged between the tightening nut and the second buffer block 92, one end of the sleeve 913 extends abuts against the second gasket 94, and a first gasket 93 is arranged between the first buffer block 91 and the second protruding step 326.

[0100] The above structure uses the compression of the buffer block instead of the torque, which is more accurate and can prevent the torque error from causing adverse effects on vibration and noise. In addition, the buffer block can also release the eccentric force caused by the shaking of the connecting part from the supporting direction, further reducing vibration and noise.

[0101] In particular, the spherical support surface 911 of the first buffer block 91 is assembled in the spherical groove 222 of the matching connector 22, so that local damage to the first buffer block 91 caused by the tilting and squeezing of the connector 22 can be avoided both during the assembly process and the operation process.

[0102] like Figures 3 to 7 As shown, the present invention provides a clothing processing device, including a box body 1, an outer barrel 2 and a shock absorbing assembly 3, the outer barrel 2 is arranged in the box body 1, and the shock absorbing assembly 3 is respectively connected to the box body 1 and the outer barrel 2, and is used to suspend the outer barrel 2 in the box body 1.

[0103] The clothes processing device further includes an inner tub rotatably disposed in the outer tub 2; a pulsator rotatably mounted in the inner tub, or may be integrally mounted with the inner tub; and a driving device mounted below the outer tub 2, driving the inner tub and the pulsator to rotate separately or together through a rotating shaft. The above structure is prior art and will not be described one by one here.

[0104] The shock absorbing assembly 3 includes a suspension shock absorbing member 31 and a support shock absorbing member 32. One end of the suspension shock absorbing member 31 is connected to the upper part of the box body 1, and the other end is suspended and connected to the upper part of the outer barrel 2; one end of the support shock absorbing member 32 is connected to the lower part of the box body 1, and the other end is supported and connected to the lower part of the outer barrel 2.

[0105] The present invention installs a suspension shock-absorbing component 31 on the upper part of the box body 1 and a supporting shock-absorbing component 32 on the lower part, so that the upper part of the outer barrel 2 is suspended and the lower part is supported in the box body 1. Compared with the method of using a suspension rod shock-absorbing structure in the prior art, the horizontal displacement of the outer barrel 2 during rotation can be reduced, the collision between the outer barrel 2 and the box body 1 due to vibration can be avoided, the stability of the outer barrel 2 during rotation can be improved, and the collision noise can be avoided.

[0106] This is because the existing pulsator washing machine is suspended on the upper part of the box body 1 through the suspension rod suspension assembly, and the other end extends downward and is suspended on the lower part of the outer barrel 2 near the bottom of the outer barrel. When there are more clothes to be washed, the overall center of gravity of the outer barrel 2 is higher, higher than the suspension position of the suspension rod suspension assembly and the outer barrel 2. During the washing and dehydration process, the upper part of the outer barrel 2 will be horizontally offset, shake violently and even hit the box body 1. Even if the bottom is supported and damped, since the upper part of the outer barrel 2 is in a suspended state, it will still shake during operation. The present invention can reduce the shaking amplitude of the outer barrel 2 and improve the stability of the outer barrel 2 in the box body 1 through the coordinated cooperation of the suspension damping member 31 and the support damping member 32, so as to achieve the purpose of good shock absorption effect. Furthermore, since the outer barrel 2 shakes less and is more stable in the box body 1, it can be designed to make the gap between the outer barrel 2 and the box body 1 smaller, expand the size of the outer barrel 2, and relatively expand the volume of the outer barrel 2.

[0107] The box body 1 of the present invention includes a base 12 and a shell 10, and the shell 10 constitutes the surrounding appearance of the clothing processing device and is supported on the base 12. One end of the support shock-absorbing member 32 is supported on the base 12, and the vibration of the outer barrel 2 can be transmitted to the base 12 at the lower part of the box body 1 through the support shock-absorbing member 32. Generally speaking, the overall strength of the base 12 is much higher than the strength of the shell 10, and the base 12 is supported on the ground, and its supporting strength is higher; compared with the method of using a suspension rod shock-absorbing structure in the related art, the suspension rod can be prevented from transmitting vibration to the shell 10, thereby reducing the vibration amplitude of the box body 1, improving the stability of the box body 1, and further reducing the noise of the clothing processing device when it is working.

[0108] Preferably, the number of the suspension damping members 31 and the number of the supporting damping members 32 are the same, that is, four are provided, and the four suspension damping members 31 and the four supporting damping members 32 are evenly distributed along the circumference of the upper part of the outer barrel 2 and the circumference of the lower part of the outer barrel 2. The corresponding position of the box body 1 connected thereto is located at the corner of the adjacent side wall of the box body 1.

[0109] In the present invention, the upper portion of the outer barrel 2 connected to the other end of the suspension damping member 31 is a region ranging from the top of the outer barrel 2 downward to the half height of the outer barrel 2 .

[0110] Preferably, the area ranges from the top of the outer barrel 2 downward to one third of the height of the outer barrel 2 from the top.

[0111] More preferably, the position is close to the mouth of the outer barrel 2. In this way, no matter how much clothes the clothing processing device processes, the shaking degree of the outer barrel 2 is not obvious.

[0112] The position where the suspension shock-absorbing member 31 of the present invention is connected to the box body 1 is adjustable;

[0113] Preferably, the upper part of the box body 1 is provided with at least two connection positions different in the height direction for adjusting the height of the connection with the suspension shock absorber 31. That is to say, the height of the suspension shock absorber 31 connected to the upper part of the box body 1 can be adjusted according to the designed volume of the outer barrel 2, so that even if a large-volume outer barrel 2 is used, it can work stably without large shaking.

[0114] The suspension shock-absorbing member 31 of the present invention is a suspension spring, which improves the stability of the upper part of the outer barrel 2 by a hanging manner.

[0115] like Figure 3 and Figure 7 As shown, a box reinforcement part 11 is provided on the upper part of the box body 1, and the box reinforcement part 11 is provided with at least one hanging hole 111 in the direction of the outer barrel 2, preferably at least two hanging holes 111 different in height direction, for installing the hook at one end of the hanging spring; and / or, a barrel reinforcement part 21 is provided on the upper peripheral wall of the outer barrel 2, and the barrel reinforcement part 21 protrudes from the outer surface of the upper peripheral wall of the outer barrel 2, and is provided with at least one hanging hole 211, for installing the hook at the other end of the hanging spring. By installing the box reinforcement part 11 and the barrel reinforcement part 21, the connection strength between the hanging spring and the box body 1 and the outer barrel 2 is improved.

[0116] The other end of the supporting shock absorbing member 32 of the present invention is connected to the lower part of the outer barrel 2 , and the connection position extends from the bottom of the outer barrel 2 upward to the area of ​​half the height of the outer barrel 2 .

[0117] Preferably, the area is from the bottom of the outer barrel 2 upward to one third of the height of the outer barrel 2 from the bottom;

[0118] A more preferred arrangement is a position close to the bottom of the outer barrel 2 . By arranging it in this manner, a larger outer barrel 2 can be designed without colliding with the box body 1 .

[0119] Preferably, the support shock absorber 32 is tilted relative to the axial direction of the outer tub 2, the angle between the axis of the support shock absorber 32 and the axis of the outer tub 2 is greater than 0°, and the lower end of the support shock absorber 32 is located outside the upper end of the support shock absorber 32 in the radial direction of the outer tub 2, preferably in the same radial direction of the outer tub 2, thereby not only improving the support stability of the support shock absorber 32 on the outer tub 2, but also improving the shock absorbing effect of the support shock absorber 32 on the outer tub 2. In addition, by tilting the support shock absorber 32, the greater the load, the more effective the limiting effect of the support shock absorber 32 on the vibration of the clothes processing device, so that it can adapt to supporting the washing of clothes of different weights to adjust the vibration of the clothes processing device.

[0120] like Figure 4 As shown, the supporting shock-absorbing member 32 includes a damper 321 and a shock-absorbing elastic member 322. One end of the damper 321 is installed at the lower part of the housing 1 and the other end supports the outer barrel 2. The shock-absorbing elastic member 322 is mounted on the damper 321. Compared with the method of using elastic members alone for shock absorption, it is possible to avoid the problem of reducing the stiffness of the elastic members to ensure the shock absorption effect, thereby shortening the life of the elastic members and premature failure of the elastic members. Compared with the method of using the damper 321 alone for shock absorption, it is possible to avoid the difficulty in speeding up the clothing processing equipment and ensure the washing efficiency. In other words, the supporting shock-absorbing member 32 can avoid the defects of using a single shock absorption method, ensure the stability of the outer barrel 2, and reduce the noise of the clothing processing equipment during operation.

[0121] The damper 321 includes a damping inner rod 3211 and a damping outer cylinder 3212. The damping inner rod 3211 is connected to the outer barrel 2. The damping outer cylinder 3212 is movably sleeved on the damping inner rod 3211 along the axial direction of the damping inner rod 3211. The damping outer cylinder 3212 is mounted on the base 12 of the box body 1, and the shock-absorbing elastic member 322 is respectively connected to the damping outer cylinder 3212 and the damping inner rod 3211. Of course, it can also be configured that the damping outer cylinder 3212 is connected to the outer barrel 2, and the damping inner rod 3211 is mounted on the base 12 of the box body 1. In this way, the relative movement between the damping inner rod 3211 and the damping outer cylinder 3212 or the compressed fluid of the two can be used to provide a damping force on the outer barrel 2, and the eccentricity or displacement caused by the outer barrel 2 can be buffered to ensure the shock-absorbing effect on the outer barrel 2.

[0122] The damping elastic member 322 is a spring and is sleeved on the damping inner rod 3211, with one end abutting against the second protruding step 326 and the other end abutting against the damping outer cylinder 3212. The damper 321 is a friction damper or an air damper. This not only facilitates the installation of the damping elastic member 322, but also allows the damping inner rod 3211 to be used to position the damping elastic member 322 to prevent the damping elastic member 322 from shifting. At the same time, the friction of the damper 321 can be relied on to reduce the energy of the vibration, making it easier to control the vibration of the outer barrel 2.

[0123] like Figure 3 and Figure 4 As shown, the laundry processing device of the present invention further includes a supporting foot 5 .

[0124] The supporting legs 5 are used to support the box body 1 so that the box body 1 is suspended in the air; the mounting seat 4 corresponds one-to-one with the supporting legs 5 and the supporting shock absorber 32, integrating the supporting legs 5 and the supporting shock absorber 32 into an independent mounting structure, which is installed on the base 12 at the lower part of the box body 1.

[0125] The supporting foot 5 and the supporting shock absorber 32 are integrated on the mounting base 4. The supporting force borne by the supporting shock absorber 32 can be effectively transmitted to the supporting foot 5, further improving the impact strength of the base 12, and transmitting the vibration to the ground through the supporting foot 5, avoiding the noise generated by the vibration of the box 1.

[0126] like Figure 3 and Figure 4 As shown, one end of the damper 321, that is, the second mounting rod 325 extending from the upper end of the damping inner rod 3211 is connected to the connecting member 22 at the lower part of the outer barrel 2. The connecting member 22 can be an individual installed on the outer barrel 2 separately, or a structure designed integrally with the outer barrel 2. The connecting member 22 is provided with a mounting hole 221. The second mounting rod 325 at the upper end of the damping inner rod 3211 passes through the mounting hole 221 of the connecting member 22 and is tightened and fixed by the second fastener 8. The second mounting rod 325 is sequentially sleeved with a first buffer block 91 and a first gasket 93 below the connecting member 22, sandwiched between the connecting member 22 and the second protruding step 326. The second mounting rod 325 is sequentially sleeved with a second buffer block 92 and a second gasket 94 above the connecting member 22, sandwiched between the connecting member 22 and the second fastener 8. A shock-absorbing elastic member 322 is sleeved on the damping inner rod 3211, abutting between the second protruding step 326 and the damping outer cylinder 3212.

[0127] The other end of the damper 321, i.e., the damping outer cylinder 3212, is mounted on the mounting seat 4, and the mounting seat 4 is fixedly supported on the base 12. A first mounting rod 323 is axially provided at the lower end of the damping outer cylinder 3212, and a first protruding step 324 is provided at one end of the first mounting rod 323 close to the damping outer cylinder 3212. A third gasket 72 and a third buffer block 71 are sleeved on the first mounting rod 323, and are located between the first protruding step 324 and the mounting seat 4. The third buffer block 71 is supported in the sink 41 corresponding to the first mounting position 411; the lower end of the first mounting rod 323 extends through the bottom through hole 413 of the sink 41, and is sleeved with a fourth gasket 73, and the first fastener 6 is screwed and tightened with the lower end of the first mounting rod 323, so that the third gasket 72 and the third buffer block 71 are pressed between the first protruding step 324 and the mounting seat 4, and the fourth gasket 73 is pressed between the mounting seat 4 and the first fastener 6.

[0128] The above structure can not only enhance the strength of the base 12 and further ensure the stability of the damper 321, but also facilitate reducing the strength requirement of the housing 1, thereby reducing the production cost of the clothing processing device.

[0129] like Figure 6 As shown, the base 12 of the present invention is square, and is provided with upper and lower hollow mounting portions 121 at the four corners, and the mounting portions 121 correspond one-to-one with the mounting seat 4;

[0130] The recessed groove 41 of the mounting seat 4 is embedded in the mounting portion 121 of the base 12, and the connecting portion 42 extending outward from the top opening of the recessed groove 41 is supported on the base 12 at the periphery of the mounting portion 121. The connecting portion 42 is provided with screw holes 421 and is fixedly connected to the base 12 by screws 422.

[0131] Since the mounting seat 4 is provided with a sunken groove 41, the installation method of embedding it on the base 12 can prevent the mounting seat 4 from moving on the base 12, improve the stability of the mounting seat 4 on the base 12, and further prevent the supporting shock-absorbing member 32 from translating on the mounting seat 4 and the base 12.

[0132] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above in preferred embodiments, they are not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the above-mentioned technical contents without departing from the scope of the technical solution of the present invention. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the solution of the present invention.
