Compared with the prior art, the beneficial effects of the present invention are:

A circulation drainage component of a clothing treatment equipment, including: a housing with an inner cavity, which is provided with a water inlet, a drainage outlet and a circulation outlet; and a filter, which is assembled in the inner cavity and has the function of dividing the inner cavity along its axial direction It is the first filtering part of the circulation cavity and the drainage cavity; wherein, the water inlet and the drainage outlet are connected to the drainage cavity respectively, and the circulation outlet is connected to the circulation cavity; in the drainage working mode of the circulation drainage assembly, the wash water entering the drainage cavity from the water inlet It is discharged from the drainage outlet; in the circulation working mode of the circulation drainage assembly, the washing water entering the drainage cavity from the water inlet is filtered by the first filter part and then enters the circulation cavity and is discharged from the circulation outlet. This technical solution has the following technical effects:

Clothes processing equipment includes a machine body, a barrel for washing or drying clothes, and a circulating drainage assembly. The circulating drainage assembly realizes the washing of clothes by circulating spraying and draining the washing water in the barrel. The clothes are washed or dried in the barrel. When dry, foreign objects in the clothes (such as coins and buttons, etc.) and lint on the clothes will break away from the clothes. In the subsequent washing process, they will enter the circulation drainage component with the washing water. The washing water in the circulation drainage component will be in the circulation working mode. The clothes will be re-sprayed into the barrel to clean the clothes. However, due to the blockage of lint, it will affect the washing water cycle spray process. Especially when the circulating spray water pipe is narrow, lint can easily block the spray port. As a result, the spraying is insufficient, so the circulating spraying effect is reduced, that is, the cleaning effect of the clothes is reduced. The present invention divides the inner cavity into a circulation cavity and a drainage cavity along its axial direction through the first filter part of the filter installed in the inner cavity. In the circulation working mode, the washing water enters the drainage cavity from the water inlet, and then passes through The filtration of the first filter part enters the circulation cavity, and is finally discharged from the circulation drainage assembly through the circulation water outlet. When the washing water passes through the first filter part, the first filter part filters the foreign matter and clothing lint in the washing water, and removes the foreign matter and clothing lint. Clothes lint remains on the side of the first filter part facing the drainage cavity to prevent the washing water entering the circulation chamber from containing foreign matter and clothing lint that will block the clothes spray, ensuring the clothes spray effect; in the drainage working mode, the wash water It enters the drainage cavity through the water inlet and is discharged out of the drainage outlet together with the clothing lint left in the drainage cavity.

It should be noted that the casing of the circulating drainage assembly involved in the present invention is generally a cylindrical structure, and the axial direction of the inner cavity is the axis center line direction of the casing. Taking into account other components of the circulating drainage assembly (motor, etc.) ) installation space, the length of the inner cavity in the axial direction must be greater than the maximum width of the inner cavity cross-section (the circular inner cavity is the cross-sectional diameter).

In the present invention, the first filter part is divided along the axial direction of the inner cavity. The axial length of the drainage cavity thus formed is smaller than the axial length of the inner cavity. In the drainage working mode, the wash water can pass through the drainage cavity. Generates greater water pressure and water flow energy, thereby more effectively taking away the lint and other impurities collected in the drainage cavity to avoid the problem of poor drainage caused by excessive accumulation of lint in the drainage cavity; due to the use of axial separation In this way, the first filter part only needs to match the cross-section of the inner cavity. Therefore, the outer surface area of the first filter part is small, and the washing water can fully flush the first filter part to prevent lint from accumulating in the first filter part. outer surface.

The first filter part is a filter plate with filter holes, so that the first filter part has a good filtering effect and has a simple structure, which is convenient for the washing water to take away the lint on the first filter part in the drainage mode and prevent lint. accumulate on the first filter part and affect the filtration effect of the first filter part. The periphery of the filter plate matches the inner cavity, that is, the shape of the filter plate is the same as the cross-section shape of the inner cavity, which facilitates the installation of the filter plate into the inner cavity and prevents The lint in the wash water passes between the edge of the filter plate and the cavity wall of the inner cavity.

The inner cavity is equipped with an annular boss that blocks the edge of the filter plate. When installing, push the filter into the inner cavity until the filter plate and the annular boss are offset. When it can no longer move, stop pushing the filter to facilitate the filter. Installation allows the annular boss to prevent gaps between the filter plate and the housing and to install and position the filter plate.

The filter also includes a second filter part located in the circulation chamber. The washing water entering the circulation chamber is filtered by the second filter part and then discharged from the circulation outlet. The washing water filtered by the first filter part enters the circulation chamber, and then the second filter part enters the circulation chamber. The filtering part performs secondary filtration of the washing water to further reduce the lint content in the washing water and prevent the lint in the washing water from clogging the spray nozzle during the later spraying process.

The second filter part is a baffle extending along the axial direction of the circulation chamber. When the wash water filtered by the first filter part enters the circulation chamber and flows from the circulation chamber to the circulation outlet, the baffle performs secondary filtering of the wash water. It blocks the clothing lint that has not been completely filtered by the first filtering part, and the filtered washing water enters the circulation outlet. The structure is simple and the filtering effect is good.

The filter also includes a third filter part located in the drainage cavity. The washing water entering the drainage cavity is filtered by the third filter part and then discharged from the drainage outlet. The third filter part controls the washing water in the drainage cavity that needs to be discharged through the drainage outlet. Filter the foreign matter in the wash water to prevent large foreign matter from getting stuck in the drain motor and affecting the normal operation of the drain motor.

The drainage outlet is arranged on the axial end wall of the housing. The third filter part blocks the drainage outlet in the axial direction of the drainage chamber. There is a radial filter gap between the third filter part and the peripheral wall of the housing. The third filter part There is an axial filtering gap between the end wall of the housing and the drainage outlet. Clothing lint is small in size and can first pass through the radial filtering gap, and then turn and pass through the axial filtering gap to be discharged out of the drainage outlet. However, the volume of coins and other debris is relatively large. Large foreign objects will be blocked to achieve foreign object blocking.

Preferably, the side of the third filter part away from the drainage outlet has a tapered guide surface that gradually expands toward the direction of the drainage outlet, so that the third filter part can filter the wash water while reducing the obstruction of the shielding member. The water flow resistance of the washing water flowing into the drainage outlet from the drainage cavity prevents the accumulation of clothing lint on the blocking member.

One axial end of the housing is an opening that communicates with the inner cavity. The filter is installed or detached from the inner cavity through the opening. The detachable connection structure facilitates cleaning or replacement of the filter, making it more convenient to use. The first filter part is along the inner cavity. The axial separation makes it possible that no matter what angle the filter is installed or how it rotates in the inner cavity, the first filter part always firmly separates the drainage outlet and the circulation outlet, and there will be no drainage outlet and circulation outlet. Without the separation of the first filter part, it is convenient to install and use the filter.

The present invention also provides a clothes treatment device, including the above-mentioned circulating drainage assembly.

The features and advantages of the present invention will be disclosed in detail in the following detailed description and drawings.

Example 1:

The circulation drainage assembly of the clothing treatment equipment, as shown in Figures 1 to 5, includes a housing 100 and a filter 200. An inner cavity 140 is formed in the housing. The housing 100 is provided with water inlets 110 and 110 that are connected to the inner cavity 140 respectively. There is a drainage outlet 120 and a circulation outlet 130. The drainage outlet 120 is equipped with a drainage motor 121, and the circulation outlet 130 is equipped with a circulation motor 131.

In this embodiment, one axial end of the housing 100 is an opening 160 connected to the aforementioned inner cavity 140. The filter 200 is inserted into or detached from the inner cavity 140 through the opening 160. When the filter 200 is assembled in the inner cavity 140, the opening 160 is closed. , the detachable connection structure facilitates cleaning or replacement of the filter 200, making it more convenient to use. The filter 200 includes a first filter part 210, a second filter part 220, a third filter part 230 and a mounting cover 240 for assembling the filter 200 to the housing 100. The second filter part 220 and the third filter part 230 are connected respectively. On both sides of the first filter part 210, the mounting cover 240 is connected to the end of the second filter part 220 away from the first filter part 210.

The first filter part 210 divides the inner cavity 140 into a circulation cavity 141 and a drainage cavity 142 along its axial direction. The drainage cavity 142 is connected with the drainage outlet 120 and the water inlet 110. The circulation cavity 141 is connected with the circulation outlet 130. During the circulation drainage In the cycle working mode of the component, the cycle motor 131 works, the washing water enters the drainage cavity 142 from the water inlet 110, and then enters the circulation cavity 141 after being filtered by the first filter part 210, and finally is discharged from the circulation drainage assembly through the circulation outlet 130, and the washing water When the water passes through the first filter part 210, the first filter part 210 filters the foreign matter and clothing lint in the washing water, leaving the foreign matter and clothing lint on the side of the first filter part 210 facing the drainage cavity 142 to prevent The washing water entering the circulation chamber 141 contains foreign matter and clothes lint that will block the circulation motor 131 and the clothes spray, thereby ensuring the clothes spray effect. In the drainage working mode of the circulating drainage assembly, the drainage motor 121 operates, and the washing water enters the drainage cavity 142 from the water inlet 110 and is discharged out of the drainage outlet 120 together with the clothes lint left in the drainage cavity 142 .

It should be noted that the casing 100 of the circulating drainage assembly involved in the present invention is generally a cylindrical structure, and the axial direction of the inner cavity 140 is the axis direction of the casing 100. Taking into account other components of the circulating drainage assembly (Motor, etc.) installation space, the axial length of the inner cavity 140 should be greater than the maximum width of the cross-section of the inner cavity 140 (the circular inner cavity is the cross-sectional diameter).

In the present invention, the first filter part 210 is divided along the axial direction of the inner cavity 140. The axial length of the drainage cavity 142 thus formed is smaller than the axial length of the inner cavity 140. In the drainage working mode, the wash water passes through The drainage cavity 142 can generate greater water pressure and water flow energy, thereby more effectively taking away the lint and other impurities collected in the drainage cavity 142, so as to avoid excessive lint accumulation in the drainage cavity 142 and causing poor drainage. Problem: Due to the axial separation method, the first filter part 210 only needs to match the cross-section of the inner cavity 140. Therefore, the area of the outer surface of the first filter part 210 is small, and the wash water can fully clean the first filter part 210. The flushing prevents wire debris from accumulating on the outer surface of the first filter part 210; and the first filter part 210 is separated along the axial direction of the inner cavity 140, so that no matter what angle the filter 200 is installed or how it rotates in the inner cavity 140 , the first filter part 210 always firmly separates the drainage outlet 120 and the circulation outlet 130, and there will be no situation where the drainage outlet 120 and the circulation outlet 130 are not separated by the first filter part 210, which facilitates the operation of the filter 200 Install and use. Preferably, the first filter part 210 is a filter plate with filter holes 211, and the periphery of the filter plate matches the inner cavity 140, that is, the shape of the filter plate is the same as the cross-section shape of the inner cavity 140, which facilitates the installation of the filter plate into the inner cavity. 140, and prevent the lint in the washing water from passing between the edge of the filter plate and the cavity wall of the inner cavity 140. The filter plate is perpendicular to the central axis of the inner cavity 140, so that the first filter part 210 has a good filtering effect. The structure is simple, which facilitates the washing water to take away the lint on the first filter part 210 in the drainage mode, and prevents the lint from accumulating on the first filter part 210 and affecting the filtration effect of the first filter part 210. The filter hole 211 can be Round, square, oval or special shape.

The second filter part 220 is located in the circulation cavity 141. The second filter part 220 is connected between the first filter part 210 and the installation cover 240. While filtering the washing water in the circulation cavity 141, it also filters the first filter part 210. It plays a supporting role, so that the first filter part 210 is fixed on the installation cover 240 through the second filter part 220. In this embodiment, the second filter part 220 is a baffle extending axially along the circulation chamber 141. The edge of the baffle does not contact the wall of the circulation chamber 141, but is in contact with the wall of the circulation chamber 141 at the edge of the baffle. There is a certain gap between them. When the washing water filtered by the first filter part 210 enters the circulation chamber 141 and flows from the circulation chamber 141 to the circulation outlet 130, the baffle performs secondary filtration of the washing water, and the unused water is filtered by the baffle. The completely filtered clothing lint in the first filter part 210 forms a barrier, and the washing water passes through the gap. The filtered washing water enters the circulation outlet 130 to further reduce the lint content in the washing water and prevent the lint from being sprayed in the later stage. The spray nozzle may be clogged. Preferably, there are a plurality of baffles, the plurality of baffles are distributed around the axis of the housing, and the angles between adjacent baffles are the same. The plurality of baffles enhance the strength of the second filter part 220 and at the same time protect the filter. The clothing lint in the washing water is blocked many times, and the filtration effect is better.

It can be understood that the second filter part 220 may also be a filter screen disposed in the circulation chamber 141 . The filter screen can be arranged parallel to the filter plate, so that the washing water passes through the filter plate and the filter screen successively, is filtered twice, and then enters the circulation outlet 130; the filter screen can also be distributed along the axis of the housing, that is, the above-mentioned baffle Replace with a filter to further filter the wash water.

The third filter part 230 is located in the drainage cavity 142 and filters the washing water in the drainage cavity 142 that needs to be discharged through the drainage outlet 120 to prevent large foreign objects in the washing water from getting stuck in the drainage motor 121 and affecting the normal operation of the drainage motor 121 . The drainage outlet 120 is provided on the axial end wall of the housing 100. The third filter part 230 includes a connector 232 connected to the first filter part 210 and a shield 233 fixed on the end of the connector 232. The shield 233 is used for drainage. The cavity 142 blocks the drainage outlet 120 in the axial direction, so that there is a radial filtering gap T ₂ between the blocking member 233 and the peripheral wall of the housing 100 , and there is an axis between the blocking member 233 and the end wall of the housing 100 where the drainage outlet 120 is provided. To the filter gap T ₁ , as shown in Figure 3 , the radial filter gap T ₂ and the axial filter gap T ₁ preferably satisfy 3mm≤T ₁ ≤8mm and 3mm≤T ₂ ≤8mm, that is, the wash water in the drainage cavity 142 and clothing lint first pass through the axial filter gap and then enter the drainage outlet 120 through the radial filter gap. During this process, foreign objects (such as coins, etc.) in the washing water will be blocked by the blocking member 233 and cannot pass through the axial filter. The gap and the radial filter gap are left in the drainage cavity 142 for the user to take out from the circulation drainage assembly after washing to prevent foreign matter from getting stuck in the drainage motor 121 and affecting the normal operation of the drainage motor 121 . Preferably, the shielding member 233 is in the shape of a trumpet. The side of the shielding member 233 away from the drainage outlet 120 forms a tapered guide surface 231 that gradually expands toward the direction of the drainage outlet 120 . The tapered guide surface 231 makes the shielding member 233 While filtering the wash water, the flow resistance of the shielding member 233 to the wash water flowing from the drainage chamber 142 into the drainage outlet 120 is reduced to prevent accumulation of clothing lint on the shielding member 233 .

Preferably, in this embodiment, the interior of the housing 100 is provided with an annular boss 150 that blocks the periphery of the filter plate. During installation, the third filter part 230 first enters the inner cavity 140 through the opening 160, and then the first filter part 210 enters. In the inner cavity 140, push the filter 200 toward the drainage outlet 120 until the filter plate is against the annular boss 150. When it can no longer move, stop pushing the filter 200. At this time, remove the installation cover located at the opening 160. 240 and the housing 100 are locked to realize the installation of the filter 200 and the housing 100.

As shown in Figure 4, the width of the annular boss 150 is T ₃ , and the distance between the periphery of the filter plate and the inner wall of the housing 100 is T ₄ , which satisfies T ₃ ≥ 2T ₄ , so that even if the filter plate is inside the housing 100 When shaking, the edge of the filter plate is always in contact with the annular boss, preventing a gap from appearing between the filter plate and the annular boss 150, that is, preventing lint in the washing water from entering the circulation chamber 141 through the gap.

In order to facilitate the installation and use of the filter 200, the installation cover 240, the first filter part 210, the second filter part 220 and the third filter part 230 are integrally provided. When the housing 100 is cylindrical, the installation cover 240 is preferably It is threadedly connected to the housing 100. As shown in Figure 5, in order to facilitate the rotation of the installation cover 240, a handle 242 for easy operation can be provided on the installation cover 240. The installation cover is provided with a positioning protrusion 241. On the inner wall of the housing 100 A limiting convex rib 170 is provided. During installation, the user can tighten the mounting cover 240 to the housing 100 by turning the handle 242. During the rotation of the mounting cover 240, when the positioning protrusion 241 and the limiting protrusion When the ends of the ribs 170 are in contact with each other, it indicates that the installation cover 240 has been locked to the housing 100 and installed in place, which plays a role in installation and positioning.
