Description

Technical Field

[0001] The invention belongs to the technical field of washing machines, and in particular relates to a circulation drainage component of a clothes processing device and the clothes processing device. Background Art

[0002] At present, clothing processing equipment includes a body, a barrel for washing or drying clothes, and a circulating drainage component. The circulating drainage component washes clothes by circulating spraying and draining washing water in the barrel. When the clothes are washed or dried in the barrel, foreign objects (such as coins and buttons, etc.) and lint on the clothes will fall off the clothes and enter the circulating drainage component with the washing water in the subsequent washing process. The washing water in the circulating drainage component will be re-sprayed into the barrel to clean the clothes in the circulating working mode. However, due to the blockage of lint, the circulating spraying process of the washing water will be affected, especially when the circulating spraying water pipe is narrow, the lint can easily block the spraying port, resulting in insufficient spraying. Therefore, there is a disadvantage of reduced circulating spraying effect, that is, reduced cleaning effect of the clothes. Summary of the invention

[0003] The technical problem to be solved by the present invention is to provide a circulation drainage component of a clothing processing device which prevents lint from affecting clothing washing.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions: a circulation drainage component of a clothing processing device, comprising: a shell having an inner cavity, provided with a water inlet, a drainage outlet and a circulation outlet; and a filter, which is assembled in the inner cavity and has a first filter portion that divides the inner cavity into a circulation cavity and a drainage cavity along its axial direction; wherein the water inlet and the drainage outlet are respectively connected to the drainage cavity, and the circulation outlet is connected to the circulation cavity; in the drainage working mode of the circulation drainage component, the washing water entering the drainage cavity from the water inlet is discharged from the drainage outlet; in the circulation working mode of the circulation drainage component, the washing water entering the drainage cavity from the water inlet is filtered by the first filter portion, enters the circulation cavity and is discharged from the circulation outlet.

[0005] In the above-mentioned circulation drainage assembly of the clothing processing equipment, the first filter part is a filter plate with filter holes, and the periphery of the filter plate matches the inner cavity.

[0006] In the circulation and drainage assembly of the above-mentioned clothes processing equipment, an annular boss for stopping the periphery of the filter plate is provided in the inner cavity.

[0007] In the circulation drainage assembly of the above-mentioned clothes processing equipment, the filter also includes a second filter part located in the circulation cavity, and the washing water entering the circulation cavity is filtered by the second filter part and then discharged from the circulation water outlet.

[0008] In the above-mentioned circulation and drainage assembly of the clothes processing device, the second filter part is a baffle extending along the axial direction of the circulation chamber.

[0009] In the circulation drainage assembly of the above-mentioned clothing processing equipment, the filter also includes a third filter part located in the drainage cavity, and the washing water entering the drainage cavity is filtered by the third filter part and then discharged from the drainage outlet.

[0010] In the circulating drainage assembly of the above-mentioned clothing processing equipment, the drainage outlet is arranged on the axial end wall of the shell, the third filter part blocks the drainage outlet in the axial direction of the drainage chamber, a radial filter gap is provided between the third filter part and the peripheral wall of the shell, and an axial filter gap is provided between the third filter part and the end wall of the shell where the drainage outlet is provided.

[0011] In the above-mentioned circulation drainage assembly of the clothes processing device, the side of the third filter part facing away from the drainage outlet has a conical guide surface which gradually expands toward the drainage outlet.

[0012] In the circulation and drainage assembly of the above-mentioned clothing processing equipment, one axial end of the shell is an opening connected to the inner cavity, and the filter is installed in or removed from the inner cavity through the opening.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] A circulation drainage component of a clothing treatment device comprises: a shell having an inner cavity, provided with a water inlet, a drainage outlet and a circulation outlet; and a filter, which is assembled in the inner cavity and has a first filter portion that divides the inner cavity into a circulation cavity and a drainage cavity along its axial direction; wherein the water inlet and the drainage outlet are respectively connected to the drainage cavity, and the circulation outlet is connected to the circulation cavity; in the drainage working mode of the circulation drainage component, the washing water entering the drainage cavity from the water inlet is discharged from the drainage outlet; in the circulation working mode of the circulation drainage component, the washing water entering the drainage cavity from the water inlet is filtered by the first filter portion and then enters the circulation cavity and is discharged from the circulation outlet. This technical solution has the following technical effects:

[0015] The clothing processing device includes a machine body, a barrel for washing or drying clothes, and a circulating drainage component. The circulating drainage component washes clothes by circulating, spraying and draining washing water in the barrel. When the clothes are washed or dried in the barrel, foreign objects (such as coins and buttons, etc.) and lint on the clothes will fall off the clothes and enter the circulating drainage component with the washing water in the subsequent washing process. The washing water in the circulating drainage component will be re-sprayed into the barrel to clean the clothes in the circulating working mode. However, due to the blockage of lint, the circulating spraying process of the washing water will be affected, especially when the circulating spraying water pipe is narrow, the lint can easily block the spraying port, resulting in insufficient spraying. Therefore, there is a disadvantage of reduced circulating spraying effect, that is, reduced cleaning effect of the clothes. The present invention divides the inner cavity into a circulation cavity and a drainage cavity along its axial direction by assembling a first filter part of the filter in the inner cavity. In the circulation working mode, washing water enters the drainage cavity from the water inlet, then enters the circulation cavity through the filtration of the first filter part, and finally discharges the circulation drainage component through the circulation outlet. When the washing water passes through the first filter part, the first filter part filters foreign matter and clothing lint in the washing water, and leaves the foreign matter and clothing lint on the side of the first filter part facing the drainage cavity, thereby preventing the washing water entering the circulation cavity from containing foreign matter and clothing lint that may block clothing spraying, thereby ensuring the clothing spraying effect; in the drainage working mode, the washing water enters the drainage cavity from the water inlet, and is discharged from the drainage outlet together with the clothing lint left in the drainage cavity.

[0016] It should be noted that the shell of the circulating drainage component involved in the present invention is generally a cylindrical structure, and the axial direction of the inner cavity is the axis direction of the shell. Considering the installation space of other components (motor, etc.) on the circulating drainage component, 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).

[0017] In the present invention, the first filter portion is divided along the axial direction of the inner cavity, and the axial length of the drainage cavity formed thereby is smaller than the axial length of the inner cavity. In the drainage working mode, the washing water can generate greater water pressure and kinetic energy when passing through the drainage cavity, thereby more effectively taking away the lint and other impurities collected in the drainage cavity, so as to avoid the problem of poor drainage caused by excessive lint accumulation in the drainage cavity. Due to the axial separation method, the first filter portion only needs to match the cross-section of the inner cavity, so the area of ​​the outer surface of the first filter portion is relatively small, and the washing water can fully flush the first filter portion to prevent lint from accumulating on the outer surface of the first filter portion.

[0018] The first filter part is a filter plate with filter holes, so that the first filter part has a good filtering effect and a simple structure, which makes it easy for washing water to carry away the lint on the first filter part in the drainage working mode, and prevents the lint from accumulating on the first filter part and affecting the filtering 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 shape of the cross-section of the inner cavity, which makes it easy to install the filter plate into the inner cavity and prevents the lint in the washing water from passing between the edge of the filter plate and the cavity wall of the inner cavity.

[0019] An annular boss is provided in the inner cavity to stop the periphery of the filter plate. During installation, the filter is pushed into the inner cavity until the filter plate abuts against the annular boss. When the filter plate can no longer be moved, the filter is stopped from being pushed, which facilitates the installation of the filter. The annular boss can prevent a gap from being generated between the filter plate and the shell and can also position the filter plate for installation.

[0020] 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 performs secondary filtration on the washing water to further reduce the lint content in the washing water and prevent the lint in the washing water from causing clogging of the spray port during the later spraying process.

[0021] The second filter part is a baffle extending along the axial direction of the circulation chamber. When the washing water filtered by the first filter part enters the circulation chamber and flows from the circulation chamber to the circulation water outlet, the baffle performs secondary filtration on the washing water to block the clothing lint that has not been completely filtered by the first filter part. The filtered washing water enters the circulation water outlet. The structure is simple and the filtering effect is good.

[0022] The filter also includes a third filter part located in the drain chamber. The washing water entering the drain chamber is filtered by the third filter part and then discharged from the drain outlet. The third filter part filters foreign matter in the washing water in the drain chamber that needs to be discharged through the drain outlet to prevent large foreign matter in the washing water from getting stuck in the drain motor and affecting the normal operation of the drain motor.

[0023] The drainage outlet is arranged on the axial end wall of the shell, the third filter part blocks the drainage outlet in the axial direction of the drainage chamber, a radial filtering gap is provided between the third filter part and the peripheral wall of the shell, and an axial filtering gap is provided between the third filter part and the end wall of the shell where the drainage outlet is provided. Clothing lint is relatively small in volume and can first pass through the radial filtering gap and then turn and be discharged from the drainage outlet through the axial filtering gap. However, larger foreign objects such as coins will be blocked, thereby achieving foreign object blocking.

[0024] Preferably, the third filter portion has a conical guide surface on the side facing away from the drain outlet, which gradually expands toward the drain outlet, so that while the third filter portion filters the washing water, it reduces the flow resistance of the covering member to the washing water flowing from the drain chamber into the drain outlet, thereby preventing clothing lint from accumulating on the covering member.

[0025] One axial end of the shell is an opening connected to the inner cavity, and the filter is installed in or removed from the inner cavity through the opening. The detachable connection structure is convenient for cleaning or replacing the filter, and it is more convenient to use. The first filter part is separated along the axial direction of the inner cavity, so that no matter at what angle the filter is installed or how it is rotated in the inner cavity, the first filter part always firmly separates the drainage outlet and the circulation outlet, and the drainage outlet and the circulation outlet will not be separated by the first filter part, which is convenient for the installation and use of the filter.

[0026] The present invention also provides a clothes processing device, comprising the above-mentioned circulation drainage component.

[0041] The circulating drainage component of the clothing processing equipment proposed in the present invention comprises: a shell having an inner cavity, provided with a water inlet, a drainage outlet and a circulating water outlet; and a filter, which is assembled in the inner cavity and has a first filter portion which divides the inner cavity into a circulating cavity and a drainage cavity along its axial direction; wherein the water inlet and the drainage outlet are respectively connected to the drainage cavity, and the circulating water outlet is connected to the circulating cavity; in the drainage working mode of the circulating drainage component, the washing water entering the drainage cavity through the water inlet is discharged from the drainage outlet; in the circulation working mode of the circulating drainage component, the washing water entering the drainage cavity through the water inlet is filtered by the first filter portion, enters the circulating cavity and is discharged from the circulating water outlet. The present invention divides the inner cavity into a circulation cavity and a drainage cavity along its axial direction by assembling the first filter part of the filter in the inner cavity. In the circulation working mode, the washing water enters the drainage cavity from the water inlet, then enters the circulation cavity through the filtration of the first filter part, and finally discharges the circulation drainage assembly through the circulation outlet. When the washing water passes through the first filter part, the first filter part filters the foreign matter and clothing thread scraps in the washing water, and leaves the foreign matter and clothing thread scraps on the side of the first filter part facing the drainage cavity, so as to prevent the washing water entering the circulation cavity from having foreign matter and clothing thread scraps that will block the clothing spraying, thereby ensuring the clothing spraying effect; in the drainage working mode, the washing water enters the drainage cavity from the water inlet, and is discharged from the drainage outlet together with the clothing thread scraps left in the drainage cavity. It should be noted that the circulation drainage assembly involved in the present invention generally has a cylindrical structure, and the axial direction of the inner cavity is the axial centerline direction of the shell. Considering the installation space of other components (motor, etc.) on the circulation drainage assembly, the axial length of the inner cavity is greater than the maximum width of the inner cavity cross section (the circular inner cavity is the cross section diameter). In the present invention, the first filter portion is divided along the axial direction of the inner cavity, and the axial length of the drainage cavity formed thereby is smaller than the axial length of the inner cavity. In the drainage working mode, the washing water can generate greater water pressure and kinetic energy when passing through the drainage cavity, thereby more effectively taking away the lint and other impurities collected in the drainage cavity, so as to avoid the problem of poor drainage caused by excessive lint accumulation in the drainage cavity. Due to the axial separation method, the first filter portion only needs to match the cross-section of the inner cavity, so the area of ​​the outer surface of the first filter portion is relatively small, and the washing water can fully flush the first filter portion to prevent lint from accumulating on the outer surface of the first filter portion.

[0047] Embodiment 1:

[0048] Circulation and drainage components of laundry treatment equipment, such as Figures 1 to 5 As shown, it includes a shell 100 and a filter 200, an inner cavity 140 is formed in the shell, and the shell 100 is provided with a water inlet 110, a drainage outlet 120 and a circulation outlet 130 which are respectively connected to the inner cavity 140, a drainage motor 121 is provided in the drainage outlet 120, and a circulation motor 131 is provided in the circulation outlet 130.

[0049] In this embodiment, one axial end of the housing 100 is an opening 160 connected to the inner cavity 140, and the filter 200 is installed in or removed 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 the cleaning or replacement of the filter 200, and is 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 mounting the filter 200 on the housing 100. The second filter part 220 and the third filter part 230 are respectively connected to both sides of the first filter part 210, and the mounting cover 240 is connected to the end of the second filter part 220 away from the first filter part 210.

[0050] 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 to the drainage outlet 120 and the water inlet 110, and the circulation cavity 141 is connected to the circulation outlet 130. In the circulation working mode of the circulation drainage component, the circulation motor 131 works, and the washing water enters the drainage cavity 142 from the water inlet 110, and then enters the circulation cavity 141 through the filtration of the first filter part 210, and finally discharges the circulation drainage component through the circulation outlet 130. When the washing water passes through the first filter part 210, the first filter part 210 filters foreign matter and clothing lint in the washing water, and leaves the foreign matter and clothing lint on the side of the first filter part 210 facing the drainage cavity 142, so as to prevent the washing water entering the circulation cavity 141 from having foreign matter and clothing lint that may block the circulation motor 131 and the clothing spraying, thereby ensuring the clothing spraying effect. In the drainage working mode of the circulation drainage assembly, the drainage motor 121 works, and the washing water enters the drainage chamber 142 from the water inlet 110 and is discharged from the drainage outlet 120 together with the clothing lint remaining in the drainage chamber 142 .

[0051] It should be noted that the shell 100 of the circulating drainage component 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 shell 100. Considering the installation space of other components (motor, etc.) on the circulating drainage component, the length of the inner cavity 140 in the axial direction is greater than the maximum width of the cross section of the inner cavity 140 (the circular inner cavity is the cross-sectional diameter).

[0052] In the present invention, the first filter part 210 is divided along the axial direction of the inner cavity 140, and the axial length of the drainage cavity 142 formed thereby is smaller than the axial length of the inner cavity 140. In the drainage working mode, the washing water can generate greater water pressure and water flow energy when passing through the drainage cavity 142, thereby more effectively taking away the lint and other impurities collected in the drainage cavity 142, so as to avoid the problem of poor drainage caused by excessive accumulation of lint in the drainage cavity 142; due to the axial separation method, the first filter part 210 only needs to match the cross section of the inner cavity 140, so the first filter part 2 The outer surface area of ​​10 is small, and the washing water can fully flush the first filter part 210 to prevent the accumulation of lint on the outer surface of the first filter part 210; and the first filter part 210 is divided along the axial direction of the inner cavity 140, so that no matter at what angle the filter 200 is installed or how it is rotated in the inner cavity 140, the first filter part 210 always firmly separates the drainage outlet 120 and the circulation outlet 130, and the drainage outlet 120 and the circulation outlet 130 will not be separated by the first filter part 210, which is convenient for the installation and use of the filter 200. Preferably, the first filter portion 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 shape of the cross-section of the inner cavity 140, which facilitates the installation of the filter plate into the inner cavity 140 and prevents lint in the washing water from passing through between the edge of the filter plate and the 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 portion 210 has a good filtering effect and a simple structure, which facilitates the washing water to carry away the lint on the first filter portion 210 in the drainage working mode, and prevents the lint from accumulating on the first filter portion 210 and affecting the filtering effect of the first filter portion 210. The filter holes 211 can be circular, square, oval or irregular.

[0053] The second filter part 220 is located in the circulation chamber 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 chamber 141, it also supports the first filter part 210, 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 220 is a baffle extending axially along the circulation cavity 141. The edge of the baffle does not contact the wall of the circulation cavity 141, but a certain gap is left between the edge of the baffle and the wall of the circulation cavity 141. When the washing water filtered by the first filter 210 enters the circulation cavity 141 and flows from the circulation cavity 141 to the circulation outlet 130, the baffle performs secondary filtration on the washing water, and blocks the clothing lint that has not been completely filtered by the first filter 210. The washing water passes through the gap, and the filtered washing water enters the circulation outlet 130, further reducing the lint content in the washing water, and preventing the lint from clogging the spray port in the later spraying process. Preferably, a plurality of baffles are provided, and the plurality of baffles are distributed in the direction of the axis of the shell, and the angles between adjacent baffles are the same. The plurality of baffles enhance the strength of the second filter 220, and at the same time, the clothing lint in the washing water is blocked multiple times, and the filtering effect is better.

[0054] It is understandable that the second filter part 220 may also be a filter screen disposed in the circulation chamber 141. The filter screen may be disposed in parallel with 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 water outlet 130; the filter screen may also be distributed along the axis direction of the housing, that is, the baffle plate is replaced with the filter screen, so as to further filter the washing water.

[0055] The third filter 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, so as 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 arranged on the axial end wall of the housing 100, and the third filter 230 includes a connecting member 232 connected to the first filter 210 and a shielding member 233 fixed to the end of the connecting member 232. The shielding member 233 shields the drainage outlet 120 in the axial direction of the drainage cavity 142, so that a radial filtering gap T is formed between the shielding member 233 and the peripheral wall of the housing 100. 2 There is an axial filtering gap T between the shielding member 233 and the end wall of the housing 100 where the water outlet 120 is disposed. 1 ,like Figure 3 As shown, the radial filter clearance T 2 and axial filter clearance T 1 Preferably, 3mm≤T 1 ≤8mm and 3mm≤T 2≤8mm, that is, the washing water and clothing lint in the drainage cavity 142 first pass through the axial filter gap and then through the radial filter gap to enter the drainage outlet 120. During this process, foreign matter (such as coins, etc.) in the washing water will be blocked by the shielding member 233 and cannot pass through the axial filter gap and the radial filter gap and remain in the drainage cavity 142, so that the user can remove it from the circulation drainage assembly by himself after washing, thereby preventing the 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 trumpet-shaped, and the side of the shielding member 233 away from the drainage outlet 120 forms a conical guide surface 231 that gradually expands toward the drainage outlet 120. The conical guide surface 231 allows the shielding member 233 to reduce the water flow resistance of the shielding member 233 to the washing water flowing from the drainage cavity 142 into the drainage outlet 120 while filtering the washing water, thereby preventing clothing lint from accumulating on the shielding member 233.

[0056] Preferably, in the present embodiment, an annular boss 150 for stopping the periphery of the filter plate is provided inside the shell 100. During installation, the third filter portion 230 first enters the inner cavity 140 through the opening 160, and then the first filter portion 210 enters the inner cavity 140, and the filter 200 is pushed toward the direction of the drain outlet 120 until the filter plate abuts against the annular boss 150. When the filter 200 can no longer be moved, the pushing of the filter 200 is stopped. At this time, the installation cover 240 located at the opening 160 can be locked with the shell 100 to achieve the installation of the filter 200 and the shell 100.

[0057] like Figure 4 As shown, the width of the annular boss 150 is T 3 , the distance between the periphery of the filter plate and the inner wall of the housing 100 is T 4 , satisfying T 3 ≥2T 4 , so that even if the filter plate shakes in the housing 100, 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 the lint in the washing water from entering the circulation chamber 141 through the gap.

[0058] 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 arranged. When the housing 100 is cylindrical, the installation cover 240 is preferably threadedly connected to the housing 100, such as Figure 5As shown, in order to facilitate the rotation of the mounting cover 240, a handle 242 for easy operation can be provided on the mounting cover 240, a positioning protrusion 241 is provided on the mounting cover, and a limiting rib 170 is provided on the inner wall of the shell 100. During installation, the user can rotate the mounting cover 240 by the handle 242 to tighten the mounting cover 240 onto the shell 100. During the process of rotating the mounting cover 240, when the positioning protrusion 241 abuts against the end of the limiting rib 170, it indicates that the mounting cover 240 has been locked onto the shell 100 and installed in place, thereby playing a role in installation positioning.

[0059] Embodiment 2:

[0060] Clothes handling equipment, such as Figure 6 As shown, it includes a body, a barrel body 300 arranged in the body and a circulating drainage component 400 in Example 1. The barrel body 300 includes an outer barrel 310 and an inner barrel 320 rotatably arranged in the outer barrel 310. The inner barrel cavity of the inner barrel 320 is used to accommodate clothes and washing water. The barrel body 300 is provided with a spray port 330 connected to the inner barrel cavity.
