Description

Technical Field

[0001] The present invention belongs to the technical field of mechanical vibration and noise control, and in particular, relates to a vibration reduction device and method for a clothing processing device and the clothing processing device. Background Art

[0002] According to user satisfaction surveys, the noise of clothing processing equipment is the most concerned issue for users. The reason for this is that the vibration of various components of clothing processing equipment during the washing and dehydration process is the main source of noise in clothing processing equipment. Therefore, vibration reduction of various components of clothing processing equipment is the main means to reduce the noise of clothing processing equipment.

[0003] However, the common vibration reduction methods on the market are mostly to add structural parts for buffering, and the vibration reduction methods are relatively simple.

[0004] A Chinese patent application with application number 201721866792.6 discloses a vibration-damping and noise-reducing door panel, comprising a door frame, an outer panel and an interior panel, wherein the outer side surface of the door frame is fixedly connected to the outer panel, the inner side surface of the door frame is provided with the interior panel, and the side of the interior panel facing the door frame is fixedly connected to a plurality of iron embedded columns, and the side of the door frame facing the interior panel is provided with a plurality of embedded blind holes, the stop end of the iron embedded column is fixedly connected to a first magnet, and a second magnet is fixedly embedded in the bottom of the embedded blind hole, the magnetic south pole and magnetic north pole of the first magnet and the second magnet are in opposite directions, a magnet ring is fixedly embedded in the inner wall of the embedded blind hole, the iron embedded column is located in the embedded blind hole, the surface of the interior panel is fixedly connected to a foamed silicone plate, and the surface of the foamed silicone plate is fixedly connected to a vibration-damping rubber layer.

[0005] The above technical solution uses the magnet ring to attract the iron embedded column to ensure that the iron embedded column cannot slide out easily, improve the position stability of the interior panel, and play a role in buffering and reducing vibration when the interior panel moves toward the door frame. However, the above vibration reduction structure cannot be realized through program control.

DETAILED DESCRIPTION

[0056] 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.

[0057] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as “upper”, “lower”, “front”, “back”, “left”, “right”, “vertical”, “inside” and “outside” are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0058] 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.

[0059] like Figures 1 to 3As shown, the present invention provides a vibration reduction device for a clothes processing device 5 with intelligent control, comprising an upper bracket 1 and a lower bracket 2, wherein the lower bracket 2 is installed below the upper bracket 1, and the upper bracket 1 can move relative to the lower bracket 2 in the longitudinal direction and the transverse direction, and the distance between the two is variable; and further comprising a spacing sensing unit 16 and a force adjustment unit, both of which are arranged between the upper bracket 1 and the lower bracket 2, wherein the spacing sensing unit 16 is used to obtain the distance variation of the relative movement between the upper bracket 1 and the lower bracket 2, and the force adjustment unit is used to adjust the force between the upper bracket 1 and the lower bracket 2 according to the comparison between the distance variation and the preset variation. Compared with the prior art, the present invention compares the distance variation with the preset variation, and according to the comparison result, controls and adjusts the force between the upper bracket 1 and the lower bracket 2 through a program, so as to ensure that the vibration reduction device for the clothes processing device 5 is in the best vibration reduction state.

[0060] The upper bracket 1 and the lower bracket 2 are both in the shape of a disc, and in the assembled state, the upper bracket 1 and the lower bracket 2 are buckled with each other. In use, the upper bracket 1 and the lower bracket 2 can achieve longitudinal and lateral vibration reduction by means of the longitudinal and lateral relative movement, thereby achieving buffering of the vibration in both longitudinal and lateral directions and significantly reducing noise.

[0061] The vibration reduction device of the laundry processing apparatus 5 of the present invention further includes a force detection unit 14 , a circumferential vibration reduction mechanism 4 and a longitudinal vibration reduction mechanism 3 .

[0062] The force detection unit 14 is arranged on the upper bracket 1 or the lower bracket 2, and is used to detect the force borne by the upper bracket 1 or the lower bracket 2; the circumferential vibration reduction mechanism 4 is used to provide the damping force of the lateral vibration reduction, and the longitudinal vibration reduction mechanism 3 is used to provide the damping force of the longitudinal vibration reduction. The longitudinal vibration reduction mechanism 3 includes a vibration reduction member 31, one end of the vibration reduction member 31 is in contact with the upper bracket 1, and the other end is in contact with the lower bracket 2.

[0063] Preferably, the vibration damper 31 is a spring, at least one end of which is fixedly abutted against the corresponding bracket. The force exerted on the upper bracket 1 or the lower bracket 2 forces the spring to compress, resulting in a compression amount, and the compression amount of the spring is the change in the distance between the upper bracket 1 and the lower bracket 2.

[0064] A limiting portion 32 for installing the longitudinal vibration damping mechanism 3 is provided at the lower portion of the upper bracket 1. The limiting portion 32 is used to limit the range of motion of the vibration damping member 31. The limiting portion 32 includes a first limiting groove 321 and a second limiting groove 322. The first limiting groove 321 is provided at the lower portion of the upper bracket 1, and the opening of the first limiting groove 321 faces the lower bracket 2. The second limiting groove 322 is provided at a side of the lower bracket 2 facing the upper bracket 1, corresponding to the first limiting groove 321, and the opening faces the first limiting groove 321. The second limiting groove 322 has an arc shape extending in the circumferential direction in the transverse direction, and the second limiting groove 322 has a space for the first limiting groove 321 to move therein.

[0065] One end of the vibration damping member 31 abuts against the bottom of the first limiting groove 321, and the other end abuts against the bottom of the second limiting groove 322. In addition, the opening end of the first limiting groove 321 can extend into the second limiting groove 322, thereby ensuring that the first limiting groove 321 and the second limiting groove 322 rotate relative to each other, and even if the upper bracket 1 and the lower bracket 2 are in a longitudinally stretched state, the first limiting groove 321 at the lower part of the upper bracket 1 cannot be separated from the second limiting groove 322, causing the bidirectional vibration damping device to fail.

[0066] There are at least three longitudinal vibration damping mechanisms 3 , and the longitudinal vibration damping mechanisms 3 are evenly distributed along the circumference of the upper bracket 1 relative to the rotation center of the lower bracket 2 .

[0067] The circumferential vibration damping mechanism 4 includes a sliding portion 41, a buffer 42 and a blocking portion 43. The sliding portion 41 is slidably disposed on one of the upper bracket 1 and the lower bracket 2 along the circumferential direction, and is rotatably connected with the other bracket in the circumferential direction. The buffer 42 is disposed on both sides of the sliding portion 41 in the circumferential direction, with one end abutting against the sliding portion 41 and the other end abutting against the blocking portion 43; the blocking portion 43 is disposed on the bracket that slides relative to the sliding portion 41.

[0068] Preferably, the sliding portion 41 is a slider, which is slidably arranged on the upper surface of the lower bracket 2 along the circumferential direction, and the top surface of the slider 22 has a plugging hole 411 that can be plugged with the pin 11. A plurality of pins 11 are arranged at the lower part of the upper bracket 1, and the extension direction of the pins 11 is perpendicular to the lower surface of the upper bracket 1. The pins 11 and the plugging holes 411 are arranged correspondingly. In the assembled state, the pins 11 can be accurately inserted into the plugging holes 411 on the top surface of the slider, so as to realize the rotation of the upper bracket 1 and the slider together.

[0069] The blocking portion 43 is a fixed block, which is fixed on the upper surface of the lower bracket 2. The fixed block and the lower bracket 2 can be an integral structure or a separate structure. The fixed block and the sliding block are alternately arranged along the same circumferential direction.

[0070] The buffer member 42 is a buffer spring, which is arranged between the fixed block and the sliding block, and two ends of the buffer spring are respectively in contact with the sliding block and the fixed block.

[0071] Preferably, a slide rail 12 for the sliding part 41 to slide back and forth is arranged between adjacent blocking parts 43, and the slide rail 12 is an arc-shaped segment slide rail 12. The buffer 42 is movably arranged in the slide rail 12, and one end of the buffer 42 abuts against the sliding part 41, and the other end abuts against the buffer 42. That is to say, when the upper bracket 1 rotates together with the slider, the buffer 42 is compressed by the reciprocating slider to achieve circumferential vibration reduction.

[0072] An anti-separation component 6 is also provided between the upper bracket 1 and the lower bracket 2 to limit the range of motion of the upper bracket 1 relative to the lower bracket 2, thereby preventing the upper bracket 1 from being completely separated from the lower bracket 2 during movement, thereby causing failure of the vibration reduction structure.

[0073] The anti-detachment assembly 6 includes a connecting column 61, a limiting hole 62 and an anti-detachment nut 63. The connecting column 61 is provided on the lower surface of the upper bracket 1 and extends downward from the lower surface of the upper bracket 1. The limiting hole 62 corresponds to the connecting column 61 and is provided through the lower bracket 2. The connecting column 61 is limited to be penetrated in the limiting hole 62, and the connecting column 61 can slide in the arc-shaped limiting hole 62. One end of the connecting column 61 passing through the limiting hole 62 is provided on the anti-detachment nut 63 or the anti-detachment pin.

[0074] In the present invention, at least three connecting posts 61 are provided, and the limiting holes 62 corresponding to the connecting posts 61 are arc-shaped holes extending in the circumferential direction.

[0075] Preferably, a buffer pad 13 is further provided between the upper bracket 1 and the lower bracket 2 to limit the approach distance between the upper bracket 1 and the lower bracket 2 .

[0076] The preset change amount of the present invention includes a first-order preset change amount and a second-order preset change amount. The first-order preset change amount is smaller than the second-order preset change amount. The force adjustment unit determines that the distance change amount of the relative movement between the upper bracket 1 and the lower bracket 2 obtained by the spacing sensing unit 16 is between the first-order preset change amount and the second-order preset change amount. That is to say, the pin shaft 11 set on the upper bracket 1 is inserted into the plug hole 411 on the top surface of the slider. At this time, the annular vibration reduction mechanism 4 works to ensure that the vibration reduction device of the clothing processing equipment 5 is in the optimal state where the longitudinal vibration reduction mechanism 3 and the annular vibration reduction mechanism 4 act simultaneously.

[0077] Preferably, the force adjustment unit of the present invention includes a permanent magnet 15 and an electromagnet 21, the permanent magnet 15 is arranged on one of the brackets, and the electromagnet 21 is arranged on the other bracket, so as to control the permanent magnet 15 and the electromagnet 21 to generate attractive force or repulsive force, and then control the distance change of the relative movement between the upper bracket 1 and the lower bracket 2 to be between the first-order preset change and the second-order preset change, thereby ensuring that the longitudinal vibration reduction mechanism 3 and the annular vibration reduction mechanism 4 play a vibration reduction role at the same time.

[0078] like Figure 4 As shown, a method for applying the vibration reduction device of the above-mentioned intelligently controlled clothing processing device 5 comprises:

[0079] S1, obtaining the distance change of the relative movement between the upper bracket 1 and the lower bracket 2;

[0080] S2. Compare the distance change with the preset change to obtain a comparison result;

[0081] S3. Adjust the force between the upper bracket 1 and the lower bracket 2 according to the comparison result.

[0082] In the initial state, the upper bracket 1 and the lower bracket 2 do not move relative to each other. At this time, the distance between the upper bracket 1 and the lower bracket 2 is defined as the first distance. When the upper bracket 1 is subjected to a certain force, the upper bracket 1 will move in the direction of the lower bracket 2. After the movement, the distance between the upper bracket 1 and the lower bracket 2 is defined as the second distance. The difference between the first distance and the second distance is the change in the distance of the relative movement of the upper bracket 1 and the lower bracket 2.

[0083] Preferably, before executing S1 and obtaining the distance change of the relative movement between the upper bracket 1 and the lower bracket 2, the following steps are included:

[0084] S10 , obtaining the force borne by the upper bracket 1 or the lower bracket 2 , and comparing the force borne by the upper bracket 1 or the lower bracket 2 with a preset limit value of the vibration damping member 31 .

[0085] Preferably, the force borne by the upper bracket 1 or the lower bracket 2 is compared with 80% of the preset limit of the shock absorbing member 31 to obtain a comparison result, and the force between the upper bracket 1 and the lower bracket 2 is further adjusted according to the comparison result.

[0086] Preferably, S10, obtaining the force borne by the upper bracket 1 or the lower bracket 2, and comparing the force borne by the upper bracket 1 or the lower bracket 2 with the preset limit value of the vibration damping member 31, specifically includes:

[0087] S101, judging that the applied force does not exceed a preset limit value and the distance change does not exceed a first-order preset change amount, and adjusting the gravitational force between the upper bracket 1 and the lower bracket 2;

[0088] The distance change obtained by the relative movement of the upper bracket 1 with respect to the lower bracket 2 does not exceed the first-order preset change, that is, the force borne by the upper bracket 1 or the lower bracket 2 is small, and only the longitudinal vibration reduction mechanism 3 plays a vibration reduction role. In order to achieve a better vibration reduction effect, the gravitational force between the upper bracket 1 and the lower bracket 2 is controlled to increase the distance change. At the same time, the distance change exceeds the first-order preset change, but does not exceed the second-order preset change. The pin shaft 11 set at the lower part of the upper bracket 1 is inserted into the socket hole 411 to ensure that the annular vibration reduction mechanism 4 can also play a vibration reduction role.

[0089] S102, judging that the force does not exceed the preset limit, the distance change exceeds the first-order preset change, judging again that the distance change exceeds the second-order preset change, and adjusting the repulsive force between the upper bracket 1 and the lower bracket 2;

[0090] S103, judging that the force exceeds the preset limit value and the distance change exceeds the second-order preset change amount, adjusting the repulsive force between the upper bracket 1 and the lower bracket 2;

[0091] In steps S102 and S103, the distance change obtained by the relative movement of the upper bracket 1 to the lower bracket 2 exceeds the second-order preset change, that is, the force exerted on the upper bracket 1 or the lower bracket 2 is relatively large. Although the longitudinal vibration reduction mechanism 3 and the circumferential vibration reduction mechanism 4 both play a vibration reduction role, the pressure on the longitudinal vibration reduction mechanism 3 is relatively large. In order to maintain the best vibration reduction effect and reduce the pressure of the longitudinal vibration reduction mechanism 3, the repulsive force between the upper bracket 1 and the lower bracket 2 is adjusted so that the distance change is between the first-order preset change and the second-order preset change.

[0092] Otherwise, the force between the upper bracket 1 and the lower bracket 2 is no longer adjusted.

[0093] Preferably, adjusting the gravitational force between the upper support 1 and the lower support 2 specifically includes:

[0094] The electromagnet 21 arranged on the upper bracket 1 or the lower bracket 2 is energized in the forward direction, and the magnitude of the current of the forward power supply corresponds to the magnitude of the attractive force between the upper and lower brackets, ensuring that the distance change obtained by the movement of the upper bracket 1 relative to the lower bracket 2 is between the first-order preset change and the second-order preset change, so that the vibration reduction device of the clothing processing equipment 5 reaches the optimal vibration reduction state.

[0095] Preferably, adjusting the repulsive force between the upper bracket 1 and the lower bracket 2 specifically includes:

[0096] The difference between the applied force and the preset limit is calculated, and the magnitude of the reverse current is calculated based on the difference. The magnitude of the reverse current corresponds to the magnitude of the repulsive force between the upper and lower brackets.

[0097] Preferably, the magnitude of the reverse current can be calculated according to a set function, and such a function can be a linear function or a trigonometric function.

[0098] like Figure 5 to Figure 6 As shown, the present invention further provides a clothes processing device 5, which adopts the method of the above-mentioned intelligently controlled clothes processing device 5 vibration reduction device to perform vibration reduction control.

[0099] Taking a pulsator washing machine as an example, it includes a shell 51, which constitutes the appearance of the pulsator clothing processing device 5; a base 52, which is located below the shell 51 and is used to support the shell 51; an outer barrel 54, which is supported inside the shell 51 in a suspended manner and is used to hold washing water; an inner barrel 53, which is rotatably arranged inside the outer barrel 54 and is used to perform washing and dehydration; a pulsator 55, which is rotatably arranged inside the inner barrel 53 and is used to rotate and stir to form a washing water flow; a motor 57, which is arranged at the lower part of the outer barrel 54, and is used to simultaneously or selectively drive the inner barrel 53 and the pulsator 55 to rotate; an outer barrel shaft 56, which is rotatably arranged in the middle of the outer barrel 54, and one end of which is connected to the motor 57.

[0100] The upper bracket 1 of the vibration reduction device of the laundry processing device 5 is fixed on the bottom surface of the outer barrel 54 of the pulsator laundry processing device 5 , and the lower bracket 2 of the vibration reduction device of the laundry processing device 5 is fixed above the base 52 of the pulsator laundry processing device 5 .

[0101] The clothes processing device 5 includes multiple sets of vibration reduction devices, which are evenly arranged along the circumference of the outer tub 54 .

[0102] Working principle: When the pulsator washing machine is running, the pressure on the inner barrel 53 is relatively small, and the pressure on the upper bracket 1 is relatively small, which causes the distance change obtained by the movement of the upper bracket 1 relative to the lower bracket 2 to not exceed the first-order preset change, and the longitudinal vibration reduction mechanism 3 plays a vibration reduction role. In order to achieve a better vibration reduction effect, the gravitational force between the upper bracket 1 and the lower bracket 2 is controlled to make the distance change exceed the first-order preset change, but not exceed the second-order preset change, so that the longitudinal vibration reduction mechanism 3 and the circumferential vibration reduction mechanism 4 can jointly play a vibration reduction role; the pressure on the inner barrel 53 is relatively large, which makes the pressure on the upper bracket 1 relatively large, and the distance change exceeds the second-order preset change. In order to relieve the pressure on the upper bracket 1, the repulsive force between the upper bracket 1 and the lower bracket 2 is adjusted; when the pressure on the inner barrel 53 is relatively moderate, that is, the distance change is between the first-order preset change and the second-order preset change, the force between the upper bracket 1 and the lower bracket 2 is no longer adjusted.

[0103] The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes by using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation scheme in the above embodiment can also be further combined or replaced. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the scope of the solution of the present invention.
