For washing machine water, the water looks like clean water, and impurities such as sediment, rust, algae and the like which are invisible to naked eyes still exist. For example, in the case of tap water, sediment is often contained therein, or the tap water can carry away impurities on a part of the pipeline when conveyed through the pipeline, so that the water source of the washing machine contains impurities, which is not good for cleaning clothes, and particularly is not friendly for users who are sensitive to skin. For another example, for some self-drilling wells in rural areas, because water is not filtered, water from the water well often contains more sediment and other impurities, and users often use the precipitated water to clean clothes, but the precipitation is not thorough for cleaning the water. In order to solve the problem that washing machine water is not clean, washing machines with water purifying devices gradually appear. However, the existing water purifying apparatus generally requires manual cleaning by a user, resulting in inconvenience to the user.
In order to solve the problem that the existing water purifying device needs manual cleaning by a user, the embodiment of the application provides a water purifying device of a washing machine and the washing machine, and the water purifying device and the washing machine are described below with reference to the accompanying drawings.

The embodiment of the application provides a water purifying device 20 of a washing machine, wherein the water purifying device 20 can comprise a filter element 21 and a shell 22, the shell 22 is provided with a filtering space 220, and the filter element 21 is arranged in the filtering space 220. The housing 22 is provided with a first inlet 221, a second inlet 222, a first outlet 223, and a second outlet 224, which communicate with the filtering space 220. The first inlet 221 is for communication with a first inlet pipe of the washing machine. The second inlet 222 is for communication with a second inlet pipe of the washing machine. The first outlet 223 is for communication with a tub of the washing machine. The second outlet 224 is for communication with a drain pipe of the washing machine. The water purification apparatus 20 may have two modes of operation: a filtering mode, i.e. corresponding to the normal operation mode of the water purifying device 20, and a cleaning mode, i.e. cleaning the water purifying device 20. Illustratively, in the filtration mode, the first inlet 221 and the first outlet 223 are open and the second inlet 222 and the second outlet 224 are closed. Water entering the housing 22 from the first inlet pipe through the first inlet 221 is filtered through the filter cartridge 21 and then enters the drum of the washing machine from the first outlet 223. It will be appreciated that this process is also referred to as a water filtration process. In the cleaning mode, the second inlet 222 and the second outlet 224 are opened, and the first inlet 221 and the first outlet 223 are closed. The water entering the housing 22 from the second water inlet pipe through the second inlet 222 flushes the filter element 21 and is discharged to the outside of the washing machine through the second outlet 224.

The filter 21 is used to filter impurities from the water source. For example, please refer to fig. 1 in combination with fig. 2 and fig. 3, fig. 2 is a schematic structural diagram of a second angle of the water purifying device according to an embodiment of the present application, and fig. 3 is a schematic sectional structural diagram of the water purifying device along A-A direction shown in fig. 2. The filter element 21 may be a structure formed by a plurality of filter sheets, each filter sheet is a net structure, and the plurality of filter sheets are arranged in parallel. The material of the filter element 21 may be a material which is not easily rusted, for example, the filter element 21 may be a stainless steel material such as SUS304, so as to prevent the influence of rusting of the filter element 21 on water quality.
The housing 22 is adapted to receive the filter cartridge 21 to provide space and access for the filter cartridge 21 to filter water. The shape of the housing 22 may be cylindrical, and the filtering space 220 may be provided in accordance with the shape of the housing 22, such as a cylindrical space. Illustratively, the first inlet 221 and the first outlet 223 are oppositely disposed at both ends of the housing 22 in a horizontal direction X perpendicular to the gravitational direction Y. The filter element 21 is disposed in the filtering space 220, and the water inlet direction of the first inlet 221 may form a preset angle with the filter element 21, where the preset angle is greater than 0 ° and less than 180 °. For example, the water inlet direction of the first inlet 221 may be at a predetermined angle of 90 ° to the filter cartridge 21, thereby facilitating the flow of water through the filter cartridge 21. The first inlet 221, the filter element 21 and the first outlet 223 are arranged on the same straight line, such as a straight line in the horizontal direction, that is, the housing 22 can be horizontally placed, and the axial direction of the housing 22 is perpendicular to the horizontal direction, so that water flows from the first inlet 221 through the filter element 21 and then flows out of the first outlet 223 conveniently. The second outlet 224 is disposed on a sidewall of the housing 22 along the gravity direction Y, and it is understood that the second outlet 224 is disposed at a lower end of the housing 22, so that water or impurities in the housing 22 can flow out under the action of gravity. The second inlet 222 is also provided on a side wall of the housing 22, and the water inlet direction of the second inlet 222 may be parallel to the filter element 21 so as to wash impurities on the filter element 21, thereby facilitating cleaning of the filter element 21.
Illustratively, the aperture of the first inlet 221 may be larger than that of the second inlet 222, so that the flow rate of the water flow in the filtering mode is larger, and the water inlet time of the drum of the washing machine may be saved. It should be noted that, in some embodiments, the second inlet 222, the first outlet 223, and the second outlet 224 may be closed first, and the first inlet 221 may be opened, so that a portion of the water immersed filter element 21 may be stored in the housing 22 in the cleaning mode. The first inlet 221 is then closed and the second outlet 224 and the second inlet 222 are opened such that the inlet water at the second inlet 222 flushes the filter cartridge 21, discharging the contaminated water through the second outlet 224.
Wherein the filter element 21 may also be arranged to be rotatable relative to the housing 22, thereby facilitating cleaning of the filter element 21. For example, the filter element 21 may be configured to be at a first angle to the housing 22 under the influence of water pressure in the filtration mode, the first angle facilitating the filtration of water by the filter element 21. For another example, the filter element 21 may be made to be at a second angle to the housing 22 under the influence of water flow and water pressure in the cleaning mode, the second angle facilitating cleaning of the filter element 21.
It should be noted that, the opening and closing of the first inlet 221, the second inlet 222, the first outlet 223 and the second outlet 224 are controlled by electromagnetic valves, that is, electromagnetic valves are respectively disposed at the first inlet 221, the second inlet 222, the first outlet 223 and the second outlet 224, so as to realize the electric control of the first inlet 221, the second inlet 222, the first outlet 223 and the second outlet 224, thereby facilitating the intelligent program control of the water purifying device 20.
For example, referring to fig. 1 to 3, the water purifying device 20 may further include a dirt collecting portion 23, where the dirt collecting portion 23 is disposed below the housing 22 along the gravity direction Y. The dirt collection portion 23 may have a dirt collection space 230, and the dirt collection space 230 communicates with the filter space 220 through the second outlet 224. For example, the dirt collection space 230 is disposed directly opposite the filter element 21. The dirt collecting portion 23 is disposed between the casing 22 and the drain pipe of the washing machine, and the dirt collecting space 230 is disposed opposite to the filter element 21, so as to collect the impurities filtered by the filter element 21, and further, the impurities on the filter element 21 and the impurities collected by the dirt collecting portion 23 are discharged when the filter element 21 is cleaned.
The dirt collecting portion 23 may be prismatic, the axial direction of the dirt collecting portion 23 is perpendicular to the axial direction of the housing 22, one axial end of the dirt collecting portion 23 is connected to a circumferential side wall of the housing 22, and the dirt collecting portion 23 is disposed below the housing 22 along the gravity direction Y, so as to collect impurities filtered by the filter element 21.

The side walls 12 may include a first side wall, a second side wall, a third side wall, and a fourth side wall that are sequentially connected, and in terms of a spatial orientation, the first side wall, the second side wall, the third side wall, and the fourth side wall may be located in four orientations, respectively. For example, the first side wall may be a side wall in front of the washing machine 1, i.e., a side wall facing the user. The second side wall may be a side wall behind the washing machine 1, i.e. a side wall facing away from the user. The corresponding third and fourth sidewalls are sidewalls of the left and right sides of the washing machine 1. The water purifying device 20 is disposed in the accommodating space 11, and the water purifying device 20 is mounted on the sidewall 12, that is, the water purifying device 20 is disposed inside the washing machine 1. For example, the water purifying apparatus 20 may be mounted on the second sidewall, i.e., the sidewall at the rear of the washing machine 1. The structure of the water purifying device 20 can be referred to in fig. 1 and the above description, and will not be described again here.
Illustratively, the cylinder 30 is disposed in the accommodating space 11, and the cylinder 30 is disposed corresponding to the first outlet 223. The drum 30, i.e., the washing drum of the washing machine 1, is disposed corresponding to the first outlet 223 such that the drum 30 can receive the water filtered through the filter cartridge 21 from the first outlet 223. It should be noted that, the water purifying device 20 is disposed above the washing machine 1, for example, in the gravity direction Y, the cylinder 30 may be disposed below the water purifying device 20 to facilitate the water flow.
The first water inlet pipe 40 is installed at one side of the side wall 12 facing away from the accommodating space 11, and the first water inlet pipe 40 is used for communicating with the first inlet 221.
