Description

Technical Field

[0001] The utility model belongs to the technical field of washing equipment, and particularly relates to a filtering system for washing equipment and washing equipment with the filtering system. Background Art

[0002] Conventional pulsator washing machines typically include a housing, an outer tub suspended within the housing, and an inner tub housed within the outer tub, driven by an outer shaft. The inner shaft is connected to an agitator at the bottom of the inner tub. A drain valve is located at the bottom of the outer tub, with its water inlet connected to a drain outlet at the bottom of the outer tub. A filter is typically installed on the inner tub wall, passively filtering lint from the wash water flow. A water pump is located at the bottom of the outer tub, with its water inlet connected to a drain pipe at the bottom of the outer tub, and its outlet connected to a pipe leading to the inner tub of the washing machine. During washing, the motor drives the agitator, rotating the clothes, while the circulating water pump operates, drawing wash water from the bottom of the outer tub back into the inner tub. A filter is installed at the outlet of the water pump connection pipe to filter out lint and debris from the wash water. The filtered wash water then flows back into the inner tub, achieving clean water. This type of filter device is generally a soft filter bag or a rigid filter frame. After a period of use, the lint and debris in the filter device must be manually removed, otherwise the filter device will be blocked and bacteria will breed; and the washing water with lint and debris will entangle the water pump parts after entering the water pump. If there are harder foreign objects such as paper clips, hairpins or coins, it is easy to cause the water pump to malfunction.

[0048] See also Figures 1-6 , is an embodiment of a washing device proposed by the utility model, Figure 1-Figure 3 This is a structural diagram when the circulating water circuit is opened. Figure 4-Figure 6 This is a schematic diagram of the structure when the drainage water channel is open. A washing machine 100 includes: a housing 60, an inner tub 50, an outer tub 10, a circulation line 20, a drainage line 30, and a filter device 40. The filter device 40 is connected to both the circulation line 20 and the drainage line 30. The circulation line 20 is connected to the outer tub 10 at both ends. It is used to flow the washing water in the outer tub 10 through the circulation line 20 and then back into the outer tub 10. The circulating water is filtered by the filter device 40, and the lint and other particles carried by the circulating water are filtered into the filter device 40.

[0049] The drain line 30 is used to drain the wash water from the outer tub 10. The drain water also flushes the filter 40, removing lint from the filter 40 and automatically cleaning it. The outer tub 10 is provided with a first connection port 11, which connects to the filter. This port is used to drain the drain line 30 and return water to the circulation line 20. The circulating water in the circulation line 20 flows through the filter 40, filtering out the lint in the circulating water. The circulating water then flows back into the outer tub 10 through the first connection port 11. Within the drain line 30, the drain water flows from the first connection port 11 into the filter 40, flushing the filtered lint away. This automatically cleans the filter 40 and prevents clogging. Furthermore, flushing the filter 40 using drain water simplifies the process, allowing it to be integrated into existing procedures, eliminating the need for a dedicated cleaning procedure and re-entering the flushing water supply. In the washing process of the washing device 100, during the washing step or the rinsing step, the circulation pipe 20 is opened to filter the lint. After the washing step or the rinsing step is completed, the drainage pipe 30 is opened to drain water, and the drainage water flows through the filter device 40 to carry away the filtered lint.

[0050] In some embodiments of the present application, the filter device 40 includes a housing 41 and a filter screen 42 disposed within the housing 41. The direction of water flowing through the filter screen 42 in the circulation line 20 is opposite to the direction of water flowing through the filter screen 43 in the drainage line 30, thereby filtering the wash water and automatically flushing and cleaning the filter screen 42. The water flowing through the filter screen 42 in the drainage line 30 is used to flush away the lint filtered by the filter screen 42.

[0051] In some embodiments of the present application, the filter screen 42 has a filtering surface away from the first connection port 11 and a flushing surface closer to the first connection port 11, with the filtering surface and the flushing surface being disposed opposite each other. The filtering surface is used to block lint in the circulating water flow, while the drainage water in the drainage pipe 30 impacts the flushing surface, thereby removing the lint filtered by the filtering surface.

[0052] In some embodiments of the present application, the housing 41 has a first filter port 411, a second filter port 412, and a third filter port 413. The first filter port 411 and the second filter port 412 are connected to the drain line 30, while the first filter port 411 and the third filter port 413 are connected to the circulation line 20. The first filter port 411 is connected to the first connection port on the outer tub 10. By providing three filter ports, the housing 41 is connected to both the circulation line 20 and the drain line 30. The first filter port 411 is a shared filter port for both the circulation line 20 and the drain line 30. The third filter port 413 is located between the first filter port 411 and the second filter port 412, which increases the distance within the housing 41 through which the drain water flows, thereby ensuring a more effective flushing effect.

[0053] In some embodiments of the present application, the circulation line 20 and the drainage line 30 are not opened at the same time, and at most one of the circulation line 20 and the drainage line 30 can be opened at the same time. The filter device 40 also includes a valve plug 43 for opening and closing the second filter port 412 and the third filter port 413. The valve plug 43 is movable and is used to open and close the second filter port 412 and the third filter port 413. The valve plug 43 is used to control the opening and closing of the second filter port 412 and the third filter port 413. When the valve plug 43 moves to open one filter port, it will close the other filter port. This reduces the number of valve plugs and control components, facilitates structural simplification, and reduces costs. For example, when the valve plug 43 moves in the forward direction, the second filter port 412 can be opened and the third filter port 413 can be closed; when the valve plug 43 moves in the reverse direction, the third filter port 413 can be opened and the second filter port 412 can be closed.

[0054] In some embodiments of the present application, the housing 41 includes a shell 410, a second filter port 412, and a third filter port 413 extending outward from the shell 410. The second filter port 412 and the third filter port 413 are arranged in parallel and located on the same side of the shell 410. The definition of the second filter port 412 and the third filter port 413 facilitates the placement of the valve plug 43, ensuring that the movement of the valve plug 43 can control the opening and closing of the second filter port 412 and the third filter port 413.

[0055] In some embodiments of the present application, the filter device 40 further includes a power gear 44 for driving the valve plug 43. The middle portion of the valve plug 43 meshes with the power gear 44. One end of the valve plug 43 can extend into the second filter port 412 to close the second filter port 412, while the other end of the valve plug 43 can extend into the third filter port 413 to close the third filter port 413. By setting the power gear 44 to rotate forward and reverse, the valve plug 43 can be driven to move forward and reverse, thereby opening and closing the second filter port 412 and the third filter port 413.

[0056] In some embodiments of the present application, a second inlet is defined on the wall of the second filter port 412 to match the first end 431 of the valve plug 43. The first end 431 extends into the second filter port 412 through the second inlet. A removable seal is formed between the first end 431 and the second inlet to prevent water from leaking through the second inlet. A second sealing groove 4121 is defined within the second filter port 412 to match the first end 431. The edge of the first end 431 extends into the second sealing groove 4121, achieving a circumferential seal between the first end 431 and the inner wall of the second filter port 412, ensuring that the first end 431 shuts off the second filter port 412. A seal is provided between the first end 431 and the second inlet to prevent water from leaking out of the second filter port 412.

[0057] In some embodiments of the present application, a third inlet is defined on the wall of the third filter port 413 to mate with the second end 432 of the valve plug 43. The second end 432 extends into the third filter port 413 through the third inlet. A removable seal is formed between the second end 432 and the second inlet to prevent water from leaking through the second inlet. A third sealing groove 4131 is defined within the third filter port 413 to mate with the second end 432. The edge of the second end 432 extends into the third sealing groove 4131, achieving a circumferential seal between the second end 432 and the inner wall of the third filter port 413, ensuring that the second end 432 shuts off the third filter port 413. A seal is provided between the second end 432 and the third inlet to prevent water from leaking out of the third filter port 413.

[0058] In some embodiments of the present application, the outer tub 10 is provided with a second connection port 12 connected to the circulation pipeline 20 for allowing wash water to flow into the circulation pipeline 20. The circulation pipeline 20 is also provided with a circulation pump 21 located between the second connection port 12 and the third filter port 413. The circulation pump 21 is provided to circulate water in the circulation pipeline 20. The circulation pipeline 20 needs to be in an open state at the second connection port 12 and the circulation pump 21 is turned on before the water circulation in the circulation pipeline 20 can be started.

[0059] In some embodiments of the present application, a drain pipe 31 is connected to the second filter port 412 in the drain line 30. The housing 41 includes a shell 410 and a removable gland 415 disposed on the shell 410 to facilitate installation and removal of the filter 42. The gland 415 is provided with a first filter port 411.

[0060] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, it is still possible for a person skilled in the art to modify the technical solutions described in the above embodiments, or to replace some of the technical features therein with equivalents.
