Description

Technical Field

[0001] The present invention relates to the technical field of drainage of a non-hole inner barrel washing machine, and in particular to a drainage sealing device of the washing machine and the washing machine. Background Art

[0002] The structure of existing washing machines generally includes an inner barrel and an outer barrel. The inner barrel and the outer barrel are connected, and a dehydration hole is provided on the inner barrel for dehydration, and the outer barrel is closed as a water storage barrel. In this way, when the washing machine is working, the area between the inner barrel and the outer barrel is full of water. During the long-term use and operation of the washing machine, the area between the inner barrel and the outer barrel will be covered with dirt and thread scraps in the water. After years of use, bacteria and odor will be generated, which will have a great impact on the washing effect and user experience.

[0003] In order to solve the problem of contamination of the inner and outer barrels caused by water filling the space between the inner and outer barrels, a new type of washing machine is available that can seal the inner and outer barrels to prevent the contamination problem. A known solution is to design the inner barrel as a hole-free inner barrel, so that the inner and outer barrels are isolated, and the inner barrel acts as a water storage barrel. At the same time, in order to drain the inner barrel, an external sealing structure is placed on the drainage hole of the inner barrel to achieve the sealing of the inner barrel. In this case, the inner barrel and the outer barrel cannot rotate relative to each other; when the load in the inner barrel shakes due to the rotation of the laundry, the sealing structure also has the hidden danger of shaking, which may cause water leakage.

[0004] In addition, with the improvement of living standards, users have higher and higher requirements for the washing effect of clothes. Existing washing machines basically use the impeller to rotate and stir the water flow to wash clothes during the washing or rinsing process. The water flow formed by this washing method is relatively single, and the washing effect needs to be improved. There is a dual-power washing machine that can control the impeller and the inner drum to rotate in the opposite direction during washing and rinsing to give the water flow more power, increase the water flow mode, enhance the water flow effect, and have a better washing effect.

[0005] In summary, the present invention aims to provide a washing machine that can achieve waterless operation between barrels and at the same time has the washing method of a dual-power washing machine, thereby meeting the user's dual requirements for the cleanliness of clothes and the cleanliness of the washing machine.

[0030] The following is a detailed description of a drainage sealing device for a washing machine and a washing machine according to the present invention in conjunction with the accompanying drawings:

[0031] like Figure 1-Figure 3 As shown, a drainage sealing device of a washing machine of this embodiment, the washing machine includes an inner barrel 500, a drainage hole is provided at the bottom of the inner barrel 500, the drainage sealing device includes a sealing mechanism that can be sealed with the drainage hole, the sealing structure includes a blocking component 100 and a supporting component 600, the supporting component 600 is fixedly mounted at the bottom of the inner barrel and extends to the drainage hole, and the blocking component 100 can be relatively slidably mounted on the supporting component 600:

[0032] During washing or rinsing, the blocking component 100 seals with the drain hole, and the inner barrel contains washing water; during drainage, the blocking component 100 opens the drain hole, and the washing water in the inner barrel is discharged from the drain hole.

[0033] The drainage sealing device of this embodiment is designed based on the structure of the inner barrel itself. The sealing component of the sealing mechanism can make the inner barrel self-sealed. When the washing machine is working, no water will accumulate between the inner barrel and the outer barrel to prevent contamination. It is also an application of water-saving technology for users. In addition, after the inner barrel is self-sealed through the sealing mechanism, the inner barrel and the impeller can rotate relative to each other to realize the function of dual-power washing clothes.

[0034] As an implementation mode of this embodiment, the supporting component 600 includes a fixing portion and a sleeve portion 601, the fixing portion is fixedly installed at the bottom of the inner barrel and extends to the drain hole and is fixedly connected to the sleeve portion, and the sleeve portion 601 has a hollow slide; the blocking component 100 includes a sealing portion 101 and a connecting portion 102, and the connecting portion 102 can be slidably arranged in the hollow slide of the sleeve portion 601 to achieve sealing and separation of the sealing portion 101 and the drain hole.

[0035] Furthermore, the end of the fixing portion connected to the sleeve portion 601 and located inside the drainage hole has a smooth structure 602 for the wire scraps to slide down smoothly during drainage;

[0036] Preferably, the smooth structure 602 is a saddle-shaped structure with high ends and low middle;

[0037] Further preferably, the upper surface of the smooth structure is a downwardly curved arc surface.

[0038] Specifically, the sleeve portion 601 is a sleeve with a hollow interior, the bottom surface of the blocking component 100 has a circular sealing portion that matches the drainage hole, and the connecting portion 102 is a center rod disposed at the center of the circular sealing portion, and the center rod is inserted into the sleeve and can slide relatively;

[0039] Preferably, the blocking component 100 further includes a sealing gasket 300, and the sealing gasket 300 is arranged on the annular sealing portion.

[0040] In order to maintain the self-sealing of the blocking component 100 and the reset seal after the drain hole is opened, the sealing mechanism includes an elastic component, one end of which is abutted against the supporting component 600, and the other end is abutted against the blocking component 100. The elastic component is deformed when the blocking component 100 slides to a state separated from the drain hole, thereby realizing the elastic reset seal of the blocking component 100.

[0041] Preferably, the elastic component is initially in a compressed state to maintain a sealed fit between the blocking component and the drainage hole.

[0042] As an implementation of this embodiment, the elastic component is a compression spring 200 , which is sleeved in the hollow slideway of the sleeve portion 601 , with one end of the compression spring 200 abutting against the sleeve portion 601 and the other end abutting against the blocking component 100 .

[0043] Furthermore, a fixing buckle 700 is installed at the end of the center rod of the blocking component 100, and the upper end of the sleeve portion 601 has a limiting step extending a certain distance toward the inside of the hollow slideway. The compression spring 200 is sleeved on the center rod, with one end resting on the fixing 700 and the other end resting on the limiting step.

[0044] The blocking component described in this embodiment includes a top cover, the upper end surface of the top cover is an arc surface, and the lower end surface of the top cover has a sealing portion that seals with the drainage hole.

[0045] During drainage, the washing water flowing out through the drainage hole may enter the sleeve part 601 of the supporting component. As time goes by, if lint, dirt or debris in the washing water enters, it may affect the components inside the sleeve part 601, such as the compression spring 200, causing it to malfunction, thereby affecting the normal resetting and sealing effect of the sealing component. Therefore, in order to ensure the relative stability of the working environment of the internal components of the sleeve part 601, the sealing mechanism described in this embodiment includes a sealing component, and both ends of the sealing component are sealed and installed between the sealing component and the supporting component to form a sealed space.

[0046] Preferably, the sealing component is a sealing threaded sleeve 1000, one end of which is sealedly connected to the blocking component, and the other end is sealedly connected to the sleeve portion of the support component, forming a sealed space that completely covers the interior of the sleeve portion 601. The sealing threaded sleeve 1000 has a sealing effect and can be extended and retracted with the up and down movement of the top cover, has a simple structure, and is low in cost, and ensures the sealing of the working environment of the compression spring 200.

[0047] The assembly relationship between the various parts of the sealing mechanism of this embodiment is shown in FIG. Figure 1 First, assemble the support component 600 to the flange 400 with two screws, then assemble the blocking component 100 with the sealing gasket 300 into the hollow slide of the sleeve part 601, and clamp the compression spring 200 from the other end with the fixing buckle 700, and the installation is completed.

[0048] Working principle of the seal: the compression spring 200 is compressed, one end of the force acts on the support component 600, and the other end acts on the fixing buckle 700. The fixing buckle 700 is transmitted to the entire blocking component 100 through the central rod of the blocking component 100. The blocking component 100 presses the bottom of the inner barrel under the action of the spring force to achieve a sealing effect. Figure 1 shown.

[0049] Working principle of drainage: When preparing to drain water, the inner barrel uses a positioning structure to achieve the overlap of the sealing structure and the driving mechanism. At this time, the output end of the driving mechanism 1000 hits the fixing buckle 700, driving the top cover to move up, and a gap is generated between the top cover and the drainage hole to achieve drainage. At this time, the compression spring 200 is also compressed to the limit position. After the drainage is completed, the output end 1001 of the driving mechanism 1000 retracts, and the top cover re-seals the drainage hole under the action of the spring force. Figure 2 shown.

[0050] The drainage sealing device of this embodiment is designed with a conical design for the inner barrel and the sealing pad, so that when clothes gather near the drainage outlet, the foreign matter can be discharged more easily under the impact of the water flow and the gravity of the foreign matter itself. It is also helpful to prevent the accumulation of lint during long-term operation.

[0051] The sealing rubber pad is fixed to the top of the entire sealing structure. Considering that foreign matter is closely attached to the bottom of the inner barrel when it is discharged, the inner barrel is made of stainless steel, and its friction damping is less than the friction resistance of rubber, which is more conducive to the discharge of foreign matter. It is also helpful to prevent the accumulation of wire scraps after long-term operation.

[0052] The support member 600 adopts a saddle-shaped structure to prevent foreign matter from being stuck when it is discharged from the inner barrel. If the bracket is flat, the possibility of the foreign matter being stuck is greater. The semicircular structure design reduces damping and is also helpful in preventing the accumulation of wire scraps during long-term operation.

[0053] The sleeve portion 601 of the support component 600 can be overfitted with the central rod of the blocking component 100, effectively preventing wire scraps and foreign matter from entering the spring cavity and causing the spring to be stuck when working.

[0054] Preferably, the driving mechanism can be a drain valve, and the support of the drain valve should be larger than the diameter of the inner cylinder of the fixing buckle 700, to ensure that the thrust of the drain valve acts on the fixing buckle, to prevent the thrust from directly acting on the central rod of the blocking component 100, which may cause the plug to fall off. Threaded fixing or elastic buckle fixing can also be used here.

[0055] As an implementation of this embodiment, the washing machine includes a water collecting device 800 arranged outside the inner drum, and the drainage sealing device also includes a driving mechanism 900, which is installed on the water collecting device corresponding to the sealing mechanism, and the driving mechanism has an output end that can be extended up and down:

[0056] During washing or rinsing, the output end of the driving device retracts, the sealing mechanism cooperates with the drainage hole in a sealing manner, and the washing water is contained in the inner barrel; during drainage, the output end of the driving device extends to push the sealing mechanism open and separate it from the drainage hole, the drainage hole opens, and the washing water in the inner barrel flows out of the drainage hole to the water collecting device for discharge.

[0057] The output end 1001 of the driving device of this embodiment is a telescopic rod, which can be extended into the fastening sleeve 600 to lift up the blocking component 100.

[0058] The present embodiment also provides a washing machine, including an inner drum, a drainage hole is provided at the bottom of the inner drum, a drainage sealing device is installed at the bottom of the inner drum, including a sealing mechanism that can be sealed with the drainage hole, the sealing structure includes a blocking component and a supporting component, the supporting component is fixedly installed at the bottom of the inner drum and extends to the drainage hole, and the blocking component can be relatively slidably installed on the supporting component:

[0059] During washing or rinsing, the blocking component seals with the drain hole, and the inner barrel contains washing water; during drainage, the blocking component opens the drain hole, and the washing water in the inner barrel is discharged from the drain hole.

[0060] The washing machine of this embodiment can achieve water-free space between barrels, solving the problem that the area between the inner barrel and the outer barrel is easily contaminated. In addition, the washing machine of this embodiment can achieve dual-power washing, improve the washing effect, and meet the washing requirements of users.

[0061] The inner barrel of the present embodiment is a hole-free inner barrel. Except for a circle of dehydration holes arranged on the upper part of the barrel wall of the inner barrel of the present embodiment, the rest are closed. Preferably, the dehydration holes are arranged at the inner barrel mouth. After the balance ring is installed on the inner barrel mouth, the balance ring can hide the dehydration holes, thereby realizing a hole-free inner barrel structure in appearance.

[0062] The above 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, it is not used to limit the present invention. Any technician familiar with this patent can make some changes or modify the technical contents suggested above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the solution of the present invention.
