The base closes the bottom of the sleeve, the pressure buffer mechanism is located in the sleeve, the top of the hanger is connected to the hanger seat, and the bottom of the hanger extends into the sleeve and is connected to the pressure buffer mechanism.

[0004] In order to ensure strength, the casing is generally made of metal. The top of the casing is interference fit with the suspension rod, and the bottom is closed by the base, which makes the inside of the casing closed. During the operation of the washing machine, moisture is easily absorbed into the casing. If the user does not use the washing machine for a long time, it will cause rust inside the casing. Summary of the invention

[0005] The present application provides a vibration-damping component and a washing machine to solve the problem that the inner wall of a sleeve is easily rusted due to moisture absorption.

[0006] A first aspect of the present application provides a vibration-damping component for a washing machine, comprising a metal sleeve and a suspension rod, wherein the lower end of the suspension rod extends into the metal sleeve, and the metal sleeve is provided with at least one oil storage portion, the oil storage portion being used to store semi-fluid grease, and the lower end of the oil storage portion is provided with a grease outlet arranged in a ring on the outside of the suspension rod, so that the semi-fluid grease passing through the grease outlet enters the gap between the suspension rod and the metal sleeve.

[0007] In some possible designs, the semi-fluid grease is molybdenum disulfide grease.

[0008] In some possible designs, the oil storage portion includes an annular protrusion, which is located on the side of the metal casing away from the hanger, the annular protrusion is inclined, and the annular protrusion extends toward the top of the metal casing, a first annular cavity is provided inside the annular protrusion, a second annular cavity is provided on the metal casing and passes through the metal casing, the first annular cavity and the second annular cavity are connected to each other, and the grease outlet is located on the second annular cavity close to the hanger.

[0009] In some possible designs, the second annular cavity has the same inclination angle as the first annular cavity, and the upper end of the second annular cavity is connected to the lower end of the first annular cavity.

[0010] In some possible designs, an oil injection hole is provided on the annular protrusion. The oil injection hole communicates with the first annular cavity, and a sealing cover for controlling the opening and closing of the oil injection hole is configured on the oil injection hole.

[0011] In some possible designs, the metal sleeve includes an outer tube, a first connecting tube, and a second connecting tube. The first connecting tube is connected to the top of the outer tube. The second connecting tube communicates with the first connecting tube, and the second connecting tube is located inside the outer tube. The suspension rod passes through the first connecting tube and the second connecting tube and extends into the inner part of the outer tube. At least one of the oil storage parts is provided on each of the first connecting tube and the second connecting tube.

[0012] In some possible designs, the outer tube, the first connecting tube, and the second connecting tube are integrally formed.

[0013] In some possible designs, a delivery pump is further included. The delivery pump is used to deliver the semi-fluid grease at the bottom of the outer tube into the oil storage part on the second connecting tube.

[0014] In some possible designs, a controller is further included. The controller is communicatively connected to the delivery pump. The controller is used for:

At the same time, after the semi-fluid grease flows into the gap between the metal sleeve and the suspension rod, the frictional resistance between the two can also be reduced, thereby reducing the use noise of the vibration damping component. In addition, the requirements for the coatings on the inner and outer walls of the metal sleeve can also be indirectly reduced, thereby reducing the processing difficulty of the vibration damping component.

[0024] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed implementation manners

[0025] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below in conjunction with the drawings in the present application. Obviously, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present application.

[0026] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and do not necessarily need to be used to describe a specific order or sequence. It should be understood that such used data can be interchanged under appropriate circumstances so that the embodiments of the present invention described herein can be implemented in an order different from those illustrated or described herein, for example.

[0027] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0028] As Figure 1 shown, the vibration damping components of the washing machine mainly include a hanger seat 1, a hanger rod, a sleeve, a pressure buffer mechanism 2 and a base 3. The base 3 closes the bottom of the sleeve. The pressure buffer mechanism 2 is located inside the sleeve. The top of the hanger rod is connected to the hanger seat 1, and the bottom of the hanger rod extends into the sleeve and is connected to the pressure buffer mechanism 2. Among them, the pressure buffer mechanism 2 generally includes components such as a spring and a piston. The spring is sleeved outside the hanger rod, and the piston is located at one end of the spring close to the base 3 and can move up and down relative to the sleeve.

[0029] From Figure 1 it can be seen that after the hanger rod is inserted into the sleeve, both the upper and lower ends of the sleeve are closed. During use, the sleeve and the hanger rod will move relatively. After a long time, a gap will be generated due to friction between the sleeve and the hanger rod. Therefore, during the operation of the washing machine, moisture is easily sucked into the sleeve through this gap. And the sleeve is generally made of metal. During the period when the user does not use the washing machine, the moisture in the sleeve cannot escape, which results in the problem that the inner wall of the sleeve rusts generally within 1-2 years, seriously affecting the service life of the vibration damping components.

[0030] In order to avoid the above problems, the present application provides a vibration damping component and a washing machine. An oil storage part 300 is provided on the vibration damping component. The semi-fluid grease stored in the oil storage part 300 can flow into the gap between the metal sleeve 200 and the hanger rod through the grease outlet, realizing the sealing of the gap between the metal sleeve 200 and the hanger rod, avoiding moisture from entering the inside of the metal sleeve 200 through this gap, thereby effectively improving the rust prevention ability of the metal sleeve 200, extending the service life of the metal sleeve 200, and assisting in reducing the use noise of the vibration damping component.

[0031] The technical solutions of the present application and how the technical solutions of the present application solve the above technical problems will be described in detail below with specific embodiments. These several specific embodiments below can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below with reference to the drawings.

[0032] Please refer to Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown in the figure, this embodiment provides a vibration damping component for a washing machine, which includes a metal sleeve 200 and a suspension rod 100. The lower end of the suspension rod 100 extends into the metal sleeve 200, and the metal sleeve 200 and the suspension rod 100 can move relative to each other. It can be understood that the vibration damping component further includes Figure 1 conventional structures such as a suspension rod seat 1, a base 3, a pressure buffer mechanism 2, etc. in Figure 1 to enable the normal operation of the vibration damping component. This is well-known to those skilled in the art, and this embodiment will not elaborate on it here.

[0033] The difference of this embodiment is that at least one oil storage part 300 is arranged on the metal sleeve 200.

[0034] Wherein, an oil outlet is arranged at the lower end of the oil storage part 300. The oil outlet is annularly arranged outside the suspension rod 100, and semi-fluid grease is stored in the oil storage part 300. During the operation of the washing machine, the semi-fluid grease stored in the oil storage part 300 will automatically flow out through the oil outlet under the action of gravity. The oil outlet annularly arranged outside the suspension rod 100 can make the semi-fluid grease flowing out of the oil storage part 300 through the oil outlet enter the gap between the suspension rod 100 and the metal sleeve 200 ( Figure 5 a in Figure 5 is the gap between the metal sleeve 200 and the suspension rod 100), realizing the complete sealing of the gap between the metal sleeve 200 and the suspension rod 100.

[0035] It can be understood that the oil storage part 300 can be of any structure and can be arranged at any position, as long as it is ensured that the oil outlet is annularly arranged outside the suspension rod 100, and the oil in the oil storage part 300 can flow through the oil outlet into the gap between the metal sleeve 200 and the suspension rod 100 to realize the complete sealing of the gap between the metal sleeve 200 and the suspension rod 100.

[0036] It can be understood that when multiple oil storage parts 300 are arranged, the oil storage parts 300 can be arranged along the extension direction of the metal sleeve 200. The distance between adjacent oil storage parts 300 can be the same or different. This embodiment does not limit it here. When multiple oil storage grooves are arranged, semi-fluid grease can be added from multiple places to achieve a multiple sealing effect, thereby improving the rust prevention ability of the metal sleeve 200.

[0037] After the shock-absorbing component is installed on the washing machine, during the operation of the washing machine, relative movement will occur between the suspension rod 100 and the metal sleeve 200. At this time, the semi-fluid grease stored in the oil storage part 300 will automatically flow out through the grease outlet under the action of gravity, and the grease outlet is annularly arranged outside the suspension rod 100, so that the semi-fluid grease can flow into the gap between the suspension rod 100 and the metal sleeve 200 more evenly, realizing complete sealing of this gap, so that moisture cannot enter the metal sleeve 200 through the gap between the suspension rod 100 and the metal sleeve 200.

[0038] This enables the shock-absorbing component to have at least the following advantages:

[0039] 1. It can prevent moisture from entering the interior of the metal sleeve 200, effectively improving the rust prevention ability of the metal sleeve 200, which helps to extend the service life of the metal sleeve 200;

[0040] 2. It can greatly improve the rust prevention ability of the metal sleeve 200 under the same plating process, indirectly reducing the requirements for the plating on the inner and outer walls of the metal sleeve 200, which helps to reduce the processing difficulty of the metal sleeve 200;

[0041] 3. When the semi-fluid grease flows into the gap between the metal sleeve 200 and the suspension rod 100, it can play a good lubricating role, which helps to reduce the frictional resistance between the metal sleeve 200 and the suspension rod 100, so as to reduce the use noise of the shock-absorbing component.

[0042] In some possible implementation manners, the semi-fluid grease is molybdenum disulfide grease, which has good heat resistance, water resistance, rust prevention and extreme pressure properties, and the price is moderate. After flowing into the gap between the metal sleeve 200 and the suspension rod 100, it can not only seal the gap, play a good rust prevention role, but also play an excellent lubricating role, reducing the use noise of the shock-absorbing component.

[0043] It can be understood that common composite calcium base grease, aluminum base grease, general lithium base grease, extreme pressure lithium base grease and other greases can also be selected as the semi-fluid grease. Here is just an example, rather than restricting the types of semi-fluid grease.

[0044] In some possible embodiments, the oil storage portion 300 includes an annular protrusion 310, which is located on the side of the metal sleeve 200 away from the boom 100 and is fixedly connected to the metal sleeve 200. The annular protrusion 310 is inclined, with its lower end connected to the metal sleeve 200 and its upper end extending toward the top of the metal sleeve 200, so that the extension direction of the annular protrusion 310 and the extension direction of the metal sleeve 200 form a certain angle. A first annular cavity 320 is arranged inside the annular protrusion 310, and a second annular cavity 330 is arranged on the metal sleeve 200 and penetrates the metal sleeve 200. One end of the second annular cavity 330 is connected to the lower end of the first annular cavity 320, and the other end is a grease outlet (the side where the metal sleeve 200 is connected to the suspension rod 100). Of course, the top of the first annular cavity 320 is closed, and only an opening is set at the end connected to the second annular cavity 330, so that the semi-fluid grease can automatically flow from the first annular cavity 320 to the second annular cavity 330.

[0045] Such an arrangement enables the first annular cavity 320 and the second annular cavity 330 to together form an oil storage tank for storing semi-fluid grease. Since the first annular cavity 320 is arranged at an angle and the lower end is connected to the second annular cavity 330, during the use of the vibration damping component, the semi-fluid grease stored in the oil storage tank will automatically fill the gap between the metal sleeve 200 and the suspension rod 100 through the grease outlet under the action of gravity to seal the gap.

[0046] The annular protrusion 310 may be welded to the metal sleeve 200 , and in order to improve the sealing effect at the connection between the annular protrusion 310 and the metal sleeve 200 , the metal sleeve 200 and the annular protrusion 310 may be integrally formed.

[0047] In addition, the top of the annular protrusion 310 may be arc-shaped to improve safety in use.

[0048] Furthermore, the second annular cavity 330 has the same inclination angle as the first annular cavity 320, and the upper end of the second annular cavity 330 is connected to the lower end of the first annular cavity 320, and the lower end of the second annular cavity 330 is a grease outlet, so that the semi-fluid grease can better enter the gap between the metal sleeve 200 and the hanger 100 through the grease outlet, avoiding excessive accumulation of semi-fluid grease in the oil storage tank, thereby improving the utilization rate of the semi-fluid grease.

[0049] It is understandable that the extension direction of the second annular cavity 330 can also be perpendicular to the extension direction of the metal sleeve 200, and the semi-fluid grease in the first annular cavity 320 can automatically enter the second annular cavity 330 under the action of gravity and flow out through the second annular cavity 330.

[0050] In some possible embodiments, an oil injection hole is provided on the annular protrusion 310. The oil injection hole communicates with the first annular cavity 320, and a sealing cover for controlling the opening and closing of the oil injection hole is arranged at the oil injection hole.

[0051] Among them, the oil injection hole can be opened at the top of the annular protrusion 310 or other positions, as long as the semi-fluid grease can be smoothly injected into the oil storage tank through the oil injection hole.

[0052] Of course, the oil injection hole may not be provided. During assembly, the semi-fluid grease can be directly filled into the oil storage tank from the grease outlet. However, relatively speaking, adding an oil injection hole can improve the convenience of replenishing the semi-fluid grease.

[0053] The sealing cover can be hinged to the annular protrusion 310, or a threaded connection port can be provided at the oil injection hole for threaded connection with the sealing cover, or the sealing cover and the annular protrusion 310 can be directly connected by bolts. Of course, other connection methods can also be used, as long as the opening and closing of the oil injection hole can be achieved through the sealing cover.

[0054] In some possible embodiments, the metal sleeve 200 includes an outer tube 210, a first connecting tube 220, and a second connecting tube 230. A connection port is provided at the top of the outer tube 210. The bottom of the first connecting tube 220 communicates with the connection port. The second connecting tube 230 is located inside the outer tube 210, and the top of the second connecting tube 230 communicates with the bottom of the first connecting tube 220. That is, the outer tube 210, the first connecting tube 220, and the second connecting tube 230 are connected at the connection port of the outer tube 210. The suspension rod 100 passes through the first connecting tube 220 and the second connecting tube 230 and extends into the inner part of the outer tube 210. At the same time, at least one oil storage part 300 is provided on each of the first connecting tube 220 and the second connecting tube 230 to perform multiple seals on the gap between the metal sleeve 200 and the suspension rod 100 through the oil storage parts 300 on the first connecting tube 220 and the second connecting tube 230, effectively improving the sealing effect.

[0055] Exemplarily, an annular protrusion 310 can be provided on the first connecting tube 220 for the first-stage seal outside the outer tube 210, and an annular protrusion 310 can be provided on the second connecting tube 230 for the second-stage seal inside the outer tube 210, so as to achieve double seals on the gap between the metal sleeve 200 and the suspension rod 100 through the two annular protrusions 310.

[0056] It can be understood that the number of annular protrusions 310 on the first connecting tube 220 and the second connecting tube 230 can be determined according to actual situations. This embodiment is only an example and does not limit it.

[0057] Further, the outer tube 210, the first connecting tube 220, and the second connecting tube 230 can be integrally formed to enhance the overall strength and improve the processing convenience.

[0058] In some possible embodiments, the damping component further includes a delivery pump for delivering the semi-fluid grease at the bottom of the outer tube 210 into the oil storage portion 300 on the second connecting tube 230, so as to achieve automatic replenishment of the semi-fluid grease, which can not only reduce costs but also improve the convenience of use.

[0059] Among them, the delivery pump for delivering the semi-fluid grease and the usage method of delivering the semi-fluid grease through the delivery pump are well-known prior arts to those skilled in the art, and will not be elaborated in this embodiment.

[0060] Specifically, the annular protrusion 310 on the first connecting tube 220 is located outside the outer tube 210, and the semi-fluid grease can be directly replenished through the oil injection hole, which is relatively convenient to add. However, the annular protrusion 310 on the second connecting tube 230 is located inside the outer tube 210, and it is not convenient to directly add through the oil injection hole. The semi-fluid grease that has fallen to the bottom of the outer tube 210 is directly pumped back into the oil storage portion 300 on the second connecting tube 230 through the delivery pump for reuse, which can effectively improve the convenience of use.

[0061] In some possible embodiments, the damping component further includes a controller communicatively connected to the delivery pump, and the delivery pump can be controlled according to a certain control logic through the controller to achieve automatic recycling of the semi-fluid grease.

[0062] It can be understood that the controller can be the controller of the washing machine or an additional controller, which can be specifically selected according to the actual situation.

[0063] Meanwhile, the controller can also be connected to the control panel of the washing machine or a mobile terminal so that the user can perform personalized control according to the usage requirements.

[0064] Specifically, the controller can determine whether to start the delivery pump according to the operating parameters of the washing machine, and pump the semi-fluid grease at the bottom of the outer tube 210 into the oil storage portion 300 on the second connecting tube 230.

[0065] Exemplarily, the operating parameters of the washing machine can be the number of times the washing machine runs the washing program. For example, the controller obtains the number of times the washing machine runs, and when the washing machine runs 100 times, 120 times, 200 times or any other number of times, the delivery pump is controlled to start for a certain period of time to send the semi-fluid grease at the bottom of the outer tube 210 into the oil storage portion 300 on the second connecting tube 230.

[0066] Among them, the number of operations of the washing machine and the running time of the delivery pump each time can be determined after measurement in the laboratory. For example, after measuring in the laboratory approximately how many times the washing machine runs until the semi-fluid grease in the oil storage part 300 on the second connecting pipe 230 is exhausted, and measuring how long the delivery pump runs until the semi-fluid grease can be effectively returned to the oil storage part 300 on the second connecting pipe 230.

[0067] Exemplarily, the operating parameter of the washing machine can also be the cumulative operating duration of the washing machine. For example, the controller obtains the operating duration of the washing machine, and after the cumulative operating duration of the washing machine reaches a certain value, it controls the delivery pump to start once to send the semi-fluid grease at the bottom of the outer pipe 210 into the oil storage part 300 on the second connecting pipe 230.

[0068] It can be understood that this embodiment is only for illustration and not for limitation. Other suitable operating parameters of the washing machine can also be used by the controller as the basis for controlling the delivery pump.

[0069] The embodiment of the present application also provides a washing machine, which includes the vibration damping component in the above embodiment. The usage mode of the vibration damping component is well known to those skilled in the art and will not be elaborated herein.

[0070] In summary, after using the above vibration damping component, the washing machine can prevent moisture from entering the metal sleeve 200, improve the rust prevention ability and service life of the metal sleeve 200 under the same plating process, indirectly reduce the requirements for the plating on the inner and outer walls of the metal sleeve 200, and moreover, the semi-fluid grease can also play a good lubricating role, effectively improving the smoothness of the operation of the vibration damping component and reducing the noise during the operation of the vibration damping component.

[0071] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them. Although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
