[0057] like Figures 1 to 5 As shown, according to an embodiment of the utility model, a filtering device 20 for a clothing processing apparatus 100 is proposed, wherein the clothing processing apparatus 100 includes a body 10, a clothing processing chamber 11 is arranged on the body 10, the filtering device 20 includes a shell 21 and a filtering component 22 arranged inside the shell 21, when the filtering device 20 is arranged in the washing water of the clothing processing chamber 11, the shell 21 floats or is suspended in the washing water, so that the filtering device 20 as a whole can float or be suspended in the washing water.

[0058] Specifically, the filter device 20 includes a shell 21 and a filter assembly 22. A water inlet 2111 and a water outlet are spaced apart on the shell 21. The water inlet 2111 has a first flow cross-section, and the water outlet has a second flow cross-section. Along the direction from the water inlet 2111 to the water outlet, at least one of the first flow cross-section and the second flow cross-section is in a tapered structure. The filter assembly 22 is arranged in the shell and between the water inlet 2111 and the water outlet. The filter assembly 22 is configured to filter the fluid flowing from the water inlet to the water outlet.

[0059] According to the filter device 20 of the utility model, when the filter device 20 is used in the clothing processing equipment 100, the filter device 20 is arranged in the washing water of the clothing processing chamber 11 in a floating or suspended manner. During the process of washing clothes, the filter device 20 moves in the washing water. During the movement of the filter device 20, the washing water enters the interior of the shell 21 through the water inlet 2111 and is filtered by the filter component 22. The washing water filtered by the filter component 22 is discharged through the water outlet.

[0060] The filter device 20 is arranged in the washing water and moves with the washing water, thereby increasing the contact area with the washing water and improving the filtering effect on the washing water.

[0061] It should be understood that, in the direction from the water inlet 2111 to the water outlet, at least one of the first flow cross-section of the water inlet 2111 and the second flow cross-section of the water outlet is arranged in a tapered structure, that is, only the first flow cross-section may be a tapered structure, or only the second flow cross-section may be a tapered structure, or both the first flow cross-section and the second flow cross-section may be tapered structures.

[0062] When the first flow cross-section of the water inlet 2111 is a tapered structure in the direction from the water inlet 2111 to the water outlet, it can be known from the Bernoulli equation that the pressure at the inlet end of the water inlet 2111 (the external port of the water inlet 2111) is greater than the outlet end of the water inlet 2111 (the internal port of the water inlet 2111). Under the action of the pressure difference, the washing water can flow into the interior of the shell 21 through the water inlet 2111 in a unidirectional manner, so that the washing water can be filtered through the filter assembly 22.

[0063] When the second flow cross-section of the water outlet is a tapered structure in the direction from the water inlet 2111 to the water outlet, according to the Bernoulli equation, the pressure at the inlet end of the water outlet (the inner port of the water outlet) is greater than the outlet end of the water outlet (the outer port of the water outlet). Under the action of the pressure difference, the washing water can flow out of the shell 21 in one direction through the water outlet, so that the filtered washing water can be discharged from the filter device 20.

[0064] By setting the water inlet and / or the water outlet, the flow rate of the washing water can be increased, so that the filtering efficiency of the filtering device 20 for the washing water is effectively improved.

[0065] In some embodiments of the present invention, Figures 2 to 5 As shown, the housing 21 includes an intermediate shell 212 and an end shell 211. The intermediate shell 212 is provided with an opening 2123. The number of the openings 2123 is two. The two openings 2123 are located on opposite sides of the intermediate shell 212 and are arranged opposite to each other. At least part of the filter assembly 22 is arranged inside the intermediate shell 212. The filter assembly 22 is detachably connected to the intermediate shell 212. The number of the end shells 211 is two. Each end shell 211 is detachably connected to the intermediate shell 212 and closes one opening 2123.

[0066] Specifically, after the filter device 20 is used, the shell 21 can be opened by releasing the cooperation between the end shell 211 and the middle shell 212, so that the filter component 22 is exposed to the outside, and then the filter component 22 can be removed from the middle shell 212 by releasing the connection between the filter component 22 and the middle shell 212, so that the filter component 22 can be cleaned to reduce the situation where the filtering effect of the filter device 20 is deteriorated due to foreign matter clogging the filter component 22.

[0067] It should be noted that the connection between the filter assembly 22 and the intermediate shell 212 includes but is not limited to snap connection or connection via fasteners.

[0068] In addition, the connection between the end shell 211 and the middle shell 212 also includes but is not limited to snap connection or connection via fasteners.

[0069] In some embodiments of the present invention, Figures 2 to 5 As shown, the housing 21 includes an intermediate shell 212 and two end shells 211. The two end shells 211 are respectively installed on opposite sides of the intermediate shell 212, and each end shell 211 closes an opening 2123 of the intermediate shell 212. A water inlet 2111 is provided on each end shell 211. The number of the water inlet 2111 on each end shell 211 is one, and the water inlets 2111 on the two end shells 211 are arranged opposite to each other.

[0070] Specifically, by providing two water inlets 2111 , the water inflow into the housing 21 can be increased, thereby further improving the filtering capacity of the filter device 20 for washing water.

[0071] It should be understood that the two end shells 211 are respectively arranged facing the filter assembly 22, and a water inlet 2111 is opened on each end shell 211, so that the washing water can be filtered by utilizing different positions of the filter assembly 22, and the filter assembly 22 can be fully utilized to improve the filtering efficiency of the washing water.

[0072] It should be pointed out that, in the present application, the shape of the opening of the water inlet 2111 includes but is not limited to a circle, an ellipse, a rectangle, a triangle, a rhombus, a pentagon or a hexagon, etc.

[0073] In some embodiments of the present invention, Figures 2 to 5 As shown, a water inlet 2111 is provided on each end shell 211, and each end shell 211 has an inner wall surface facing the filter assembly 22, and a flow guide 2113 having a flow guide channel is provided on the inner wall surface, and the water inlet 2111 is connected to the filter assembly 22 through the flow guide channel. Among them, in the direction from the water inlet 2111 to the filter assembly 22, at least part of the flow cross section of the flow guide channel is a tapered structure.

[0074] Specifically, the guide member 2113 having a guide channel is arranged between the water inlet 2111 and the filter assembly 22, and the guide channel of the guide member 2113 is used to guide the washing water from the water inlet 2111 to the position of the filter assembly 22 so that the washing water is filtered by the filter assembly 22.

[0075] It should be understood that, since the guide channel of the guide member 2113 has a tapered structure (for example, a trumpet shape) in the direction from the water inlet 2111 to the filter assembly 22, at least part of the flow cross-section thereof can be known from the Bernoulli equation that the pressure at the inlet end (one side of the water inlet 2111) of the guide channel is greater than the pressure at the outlet end (one side of the filter assembly 22) of the guide channel, that is, at the position of the water inlet 2111, the external pressure of the shell 21 is greater than the internal pressure of the shell 21. Under the action of the pressure difference, the washing water can flow into the interior of the shell 21 through the water inlet 2111 so as to be filtered by the filter assembly 22.

[0076] In addition, the guide channel of the guide member 2113 has a tapered structure in at least part of its flow cross-section in the direction from the water inlet 2111 to the filter assembly 22, which can increase the speed of the washing water in the process of passing through the guide channel, thereby improving the entry efficiency of the washing water, so that the filtering efficiency of the washing water by the filter device 20 is effectively improved, and at the same time, it also plays a guiding role, further guiding the washing water into the filter assembly 22.

[0077] It should be noted that the guide member 2113 and the end shell 211 can be an integral structure or a split structure. When the guide member 2113 and the end shell 211 are an integral structure, the two can be processed and manufactured by an integral molding method (such as injection molding, etc.). When the guide member 2113 and the end shell 211 are a split structure, the two can be connected and fixed by bonding, welding, clamping or fastener connection after being processed separately.

[0078] In addition, the shape of the flow cross section of the guide channel is consistent with the opening shape of the water inlet 2111 to reduce the resistance generated when the washing water enters the guide channel through the water inlet 2111.

[0079] In some embodiments of the present invention, Figures 2 to 5 As shown, the housing 21 includes an intermediate housing 212 and two end housings 211. The two end housings 211 are respectively installed on opposite sides of the intermediate housing 212, and each end housing 211 closes an opening 2123 of the intermediate housing 212. The housing 21 is provided with a water inlet 2111 and a water outlet. Each end housing 211 is provided with a water inlet 2111, and the water inlet 2111 is arranged at the center of the end housing 211. The water inlets 2111 on the two end housings 211 are arranged opposite to each other, and the water outlets include a first water outlet 2112 and a second water outlet 2122, wherein each end housing 211 is provided with a first water outlet 2112, and the intermediate housing 212 is provided with a second water outlet 2122. The opening area of ​​the water inlet 2111 toward the inner side of the housing 21 is larger than the opening area of ​​the second water outlet toward the inner side of the housing 21 and the opening area of ​​the first water outlet 2112 toward the inner side of the housing 21.

[0080] Specifically, when the filter device 20 is in use, washing water enters the interior of the housing 21 through the two water inlets 2111, and the washing water entering the interior of the housing 21 is filtered by the filter assembly 22, and the filtered washing water is discharged through the first water outlet 2112 and the second water outlet 2122. By providing the first water outlet 2112 and the second water outlet 2122, the drainage volume of the filter device 20 can be increased, so that the filtering ability of the filter device 20 for washing water is improved.

[0081] In addition, the first water outlet 2112 is disposed on the end shell 211 , and the second water outlet 2122 is disposed on the middle shell 212 , so that multi-position drainage of the filter device 20 can be achieved.

[0082] In addition, the opening area of ​​the water inlet 2111 is set to be larger than the areas of the first water outlet 2112 and the second water outlet 2122, so that the washing water can enter the shell 21 from the water inlet 2111 and be discharged through the water outlet.

[0083] In some embodiments of the present invention, Figures 2 to 5 As shown, the first water outlet 2112 is provided on the end shell 211, and the number is multiple, and all the first water outlets 2112 are arranged at intervals in the circumferential direction of the water inlet 2111. By setting the first water inlet 2111, the drainage capacity of the filter device 20 can be further increased, thereby improving the filtering efficiency of the washing water, and the setting of multiple water outlets can reduce the risk of the water outlet being blocked and unable to drain.

[0084] In some embodiments of the present invention, Figures 2 to 5 As shown, the second water outlet 2122 is provided on the end shell 211, and there are multiple second water outlets 2122, all of which are arranged at intervals in the circumferential direction of the opening 2123. By setting the second water inlet 2111, the drainage capacity of the filter device 20 is further increased, so that the filtering efficiency of the filter device 20 for washing water is further improved.

[0085] In some embodiments of the utility model, at least one of the end shell 211 and the middle shell 212 is a floatable component. Specifically, by configuring the end shell 211 and the middle shell 212, the housing 21 can have a floating ability, and the filter device 20 can float or suspend in the washing water during use. When the filter device 20 is used in a clothes processing device, the contact area between the filter device 20 and the washing water can be further increased, thereby further improving the filtering effect on the washing water.

[0086] In the present application, at least the middle shell 212 is a floatable component, and the floatable component can be a plastic component or a silicone component, etc.

[0087] In some embodiments of the utility model, the shell 21 includes an intermediate shell 212 and two end shells 211, and the two end shells 211 are respectively installed on opposite sides of the intermediate shell 212. A protrusion 2121 structure is arranged on the outer surface of the intermediate shell 212. The number of the protrusion 2121 structures is multiple, and all the protrusion 2121 structures are arranged at intervals in the circumferential direction of the opening 2123 of the intermediate shell 212.

[0088] Specifically, during the washing process of clothes, the protrusion 2121 structure contacts the clothes, thereby reducing the tangling of clothes during the washing process.

[0089] It should be pointed out that in the present application, the protrusion 2121 structure is a convex rib with a smooth outer surface, and the convex rib is a curved structure. By setting the protrusion 2121 structure, the washing water can flow smoothly on the outer surface of the intermediate shell 212, reducing the resistance during the flow of the washing water.

[0090] In addition, the plurality of protrusions 2121 and the plurality of second water outlets 2122 are both disposed on the outer circumferential surface of the intermediate shell 212 , and along the circumferential direction of the opening 2123 of the intermediate shell 212 , the plurality of protrusions 2121 and the plurality of second water outlets 2122 are alternately disposed.

[0091] In addition, the protruding structure 2121 is a floatable part formed of a floatable material. The protruding structure 2121 can be integrally formed with the intermediate shell 212 (in this case, the intermediate shell 212 is also a floatable part formed of a floatable material), or it can be processed separately and then fixed on the intermediate shell 212.

[0092] In some embodiments of the present invention, Figures 3 to 5 As shown, the filter assembly 22 includes a first filter element 221 and a second filter element 222, the number of the first filter elements 221 is two, the second filter element 222 has two oppositely arranged ends, one end is connected to a first filter element, and the other end is connected to a first filter element 221, and the second filter element 222 is located in the area between the two ends.

[0093] Specifically, when the filter device 20 is in use, washing water enters the interior of the shell 21 through the water inlet 2111 on the two end shells 211, and the washing water entering the shell 21 first passes through the first filter element 221 for a first-stage filtration. The washing water after the first-stage filtration is subjected to a second-stage filtration by the second filter element 223, and the washing water after the second-stage filtration is discharged through the first water outlet 2112 on the end shell 211 and the second water outlet 2122 on the middle shell 212.

[0094] The first filter element 221 and the second filter element 223 are used to implement two-stage filtration of the washing water, thereby improving the filtering effect of the washing water.

[0095] It should be pointed out that, in the present application, the first filter element 221 can be a filter frame, a filter net or filter cotton, etc. In addition, the second filter element 223 can also be a filter frame, a filter net or filter cotton, etc.

[0096] In some embodiments of the present invention, Figures 3 to 5 As shown, the filter assembly 22 includes two first filter elements 221, a connecting element 222 and a second filter element 223, the connecting element 222 has a first end and a second end arranged oppositely, the first end and the second end are respectively connected to a first filter element 221, and the connecting element 222 is connected to the second filter element 222 in the area between the first end and the second end.

[0097] Specifically, the first filter element 221 and the second filter element 223 are combined by the connecting element 222 , so that the filter assembly 22 forms an integral structure, thereby improving the convenience of disassembly and assembly of the filter assembly 22 .

[0098] In some embodiments of the present invention, Figures 3 to 5 As shown, the opening 2123 includes an inner edge and an outer edge, the inner edge abuts against a first filter element 221 , and the outer edge is connected to an end shell 211 .

[0099] Specifically, when the filter assembly 22 is installed on the intermediate shell 212, the second filter element 223 is arranged in the intermediate shell 223, and the inner edge of each opening 2123 is respectively abutted against a first filter element 221. A first clamping structure is arranged around the outer edge of the opening 2123, and a second clamping structure is arranged on the end shell 211. The first clamping structure and the second clamping structure are clamped and matched with each other, so that the end shell 211 and the intermediate shell 212 are clamped and fixed, wherein one of the first clamping structure and the second clamping structure is an annular clamping groove, and the other is an annular clamping hook. The clamping matching method has a simple structure and is easy to disassemble and assemble.

[0100] In some embodiments of the present invention, Figures 3 to 5 As shown, the second filter element 223 is a cylindrical structure, and the second filter element 223 is sleeved on the connecting element 222, and the second filter element 223 is fixed relative to the connecting element 222. By setting the second filter element 223 and the connecting element 222, the structural stability of the connecting element 222 and the second filter element 223 is improved, thereby effectively improving the filtering effect.

[0101] It should be noted that the connection method between the connecting member 222 and the first filter element 221 includes but is not limited to snap-fitting or connection via fasteners, and the connection method between the connecting member 222 and the second filter element 223 is snap-fitting.

[0102] In some embodiments of the present invention, Figures 4 to 5 As shown, the filtration aperture of the first filter element 221 is larger than the filtration aperture of the second filter element 223. Specifically, the filtration apertures of the first filter element 221 and the second filter element 223 are set so that the first filter element 221 is for coarse filtration and the second filter element 223 is for fine filtration. When the washing water is filtered, it is firstly coarsely filtered by the first filter element 221 and then finely filtered by the second filter element 223. By setting the coarse filtration and fine filtration, the clogging of the filter assembly 22 is reduced, so that the filter assembly 22 can effectively filter the washing water.

[0103] In some embodiments of the present invention, Figures 1 to 5 As shown, the housing 21 is a spherical structure. By setting the housing 21 to a spherical structure, the resistance of the housing 21 to the washing water can be reduced, thereby effectively reducing the influence of the filter device 20 on the laundry washing process, so that the laundry treatment effect is improved.

[0104] In addition, in some embodiments of the present invention, the filtering device 20 may only include a shell 21. During use, under the action of the impeller of the clothing processing device 100, the washing water can enter the interior of the shell 21 through the water inlet 2111 of the shell 21, and then flow out from the water outlet of the shell 21. Inside the shell 21, when the washing water flows from the water inlet 2111 to the water outlet, foreign matter carried in the washing water is intercepted by the water outlet in the shell, thereby achieving filtration of the washing water.

[0105] like Figures 1 to 5 As shown, the second aspect of the utility model proposes a clothing processing device 100, which includes a body 10 and a filtering device 20 as described above. The body 10 includes a clothing processing chamber 11 having a water inlet 12, and the filtering device 20 is arranged at the water inlet 12 and is configured to enter the clothing processing chamber 11 along with water from the water inlet 12.

[0106] According to the clothes processing device 100 of the utility model, the filter device 20 is arranged in the washing water of the clothes processing chamber 11 in a floating or suspended manner. During the process of washing clothes, the filter device 20 moves in the washing water. During the movement of the filter device 20, the washing water enters the interior of the housing 21 through the water inlet 2111 and is filtered by the filter assembly 22. The washing water filtered by the filter assembly 22 is discharged through the water outlet. The filter device 20 is arranged in the washing water and moves with the washing water, which increases the contact area with the washing water and improves the filtering effect on the washing water. At the same time, the filter assembly 22 includes at least two-stage filtering structures, which can further improve the filtering effect on the washing water.

[0107] In some embodiments of the utility model, the above-mentioned clothing processing device can be a pulsator washing machine or an agitator washing machine, etc. In the drawings of the utility model, the clothing processing device is shown as a pulsator washing machine as an example. For the structure of other parts of the pulsator washing machine, please refer to the prior art, and this application will not go into details here.

[0108] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model shall be based on the protection scope of the claims.
