[0034] In the related art, a dry cleaning device is a washing device that uses a washing solvent to remove stains on fabrics through the chemical force of the solvent and the mechanical force of the equipment. The dry cleaning device mainly includes functions such as washing, filtering, dehydration, drying, purifying and recovering solvents and realizing recycling. The dry cleaning device includes multiple filtering devices, and the multiple filtering devices are connected in turn through connecting pipes and formed into a filtering system suitable for filtering the washing solvent. However, this will result in a large volume of the filtering system, which will result in the dry cleaning device needing to design a larger installation space for installing the filtering system, resulting in a larger volume of the dry cleaning device.

[0035] Reference below Figure 1-Figure 4 A filter device 1 for a laundry treating apparatus according to an embodiment of the present invention is described.

[0036] like Figure 1-Figure 4 As shown, the filtering device 1 according to the present invention includes: a filter housing and a filter element, at least two filter cavities are formed in the filter housing, and the at least two filter cavities are connected in sequence. An inlet 21 and an outlet 22 are formed on the filter housing, the inlet 21 is connected to one of the at least two filter cavities, and the outlet 22 is connected to the other of the at least two filter cavities. The filter element is constructed into a plurality of elements corresponding to the at least two filter cavities one by one, each filter element is accommodated in the corresponding filter cavity, and the plurality of filter elements filter the washing solvent flowing from the inlet 21 to the outlet 22 in sequence.

[0037] In some embodiments, multiple filter cavities are formed in the filter housing, which may be two filter cavities, three filter cavities, four filter cavities or any other number of filter cavities, and there is no limitation here. When three filter cavities are formed in the filter housing, the three filter cavities are respectively a first filter cavity, a second filter cavity and a third filter cavity, and the first filter cavity, the second filter cavity and the third filter cavity are connected in sequence. An inlet 21 and an outlet 22 are formed on the filter housing, and the inlet 21 is suitable for connecting with the first filter cavity, and the outlet 22 is suitable for connecting with the third filter cavity. At this time, the filter element is constructed as three and the three filter elements are respectively arranged in the first filter cavity, the second filter cavity and the third filter cavity.

[0038] When the dry cleaning device is working, the stains fall off the fabric and mix with the washing solvent to reduce the cleanliness of the washing solvent. The washing solvent enters the first filter cavity through the inlet 21. The filter element in the first filter cavity can filter the stains to initially improve the cleanliness of the washing solvent. Subsequently, the washing solvent enters the second filter cavity. The filter element in the second filter cavity can filter the stains to further improve the cleanliness of the washing solvent. Then, the washing solvent enters the third filter cavity. The filter element in the third filter cavity can filter the washing solvent again. Finally, the washing solvent that has undergone multi-stage filtration is discharged from the outlet 22.

[0039] It can be understood that a plurality of filter cavities connected in sequence are formed in the filter housing, and filter elements are respectively arranged in the plurality of filter cavities. The washing solvent passes through the plurality of filter cavities in sequence and is filtered by the filter elements in the plurality of filter cavities in sequence and then discharged. Thus, the plurality of filter cavities connected in sequence and the filter elements in the plurality of filter cavities cooperate together to construct a multi-stage filter system in the filter housing, so that the filter device 1 has a good filtering effect. At the same time, compared with the filter system in which a plurality of filter devices 1 are connected in sequence through connecting pipes, the filter system in the filter housing of the present application has a smaller volume, which can reduce the installation space of the dry cleaning device for installing the filter system, thereby reducing the volume of the dry cleaning device. Moreover, the multi-stage filter system of the present application is integrated in the filter housing, thus, the multi-stage filter system can be installed on the dry cleaning device by installing the filter housing to the dry cleaning device, which simplifies the assembly process of the dry cleaning device and improves the assembly efficiency of the dry cleaning device.

[0040] According to the filtering device 1 involved in the present invention, a plurality of filter chambers connected in sequence are arranged in the filter housing, and filter elements are respectively arranged in the plurality of filter chambers, thereby a multi-stage filtering system can be formed in the filter housing, and the multi-stage filtering system in the filter housing of the present application is small in size, which reduces the installation space of the dry cleaning device for installing the filtering system, thereby reducing the volume of the dry cleaning device, and at the same time, the multi-stage filtering system is integrated in the filter housing, which simplifies the assembly process of the dry cleaning device and improves the assembly efficiency of the dry cleaning device.

[0041] According to some embodiments of the present invention, Figure 3-Figure 4 As shown, a partition is formed in the filter housing to separate two adjacent filter chambers; wherein the partition is arranged in a surrounding manner to define two filter chambers isolated from each other in the radial direction; and / or the partition is orthogonal to the extension direction of the filter housing to define two filter chambers isolated from each other in the axial direction in the filter housing.

[0042] In some embodiments, the partition is constructed in an annular shape and extends in the axial direction. The annular partition is suitable for defining two filter cavities isolated from each other in the radial direction in the filter housing. It is worth mentioning that the annular partition can be constructed as multiple and multiple annular partitions are distributed at intervals in the radial direction. Therefore, through the above-mentioned arrangement, multiple filter cavities distributed at intervals in the radial direction can be defined, thereby improving the filtering capacity of the filtering device 1; in other embodiments, the partition extends radially and is arranged in the filter housing. The partition is suitable for defining two filter cavities isolated from each other in the axial direction in the filter housing. It is worth mentioning that the partition can be constructed as multiple and multiple partitions are distributed at intervals in the axial direction. Therefore, through the above-mentioned arrangement, multiple filter cavities distributed at intervals in the axial direction can be defined, thereby improving the filtering capacity of the filtering device 1.

[0043] In some other embodiments, the partition includes a transverse partition extending in the radial direction and an annular partition extending in the axial direction, the transverse partition is arranged in the filter shell and defines a first filter space and a second filter space isolated from each other in the axial direction in the filter shell, the annular partition is arranged in the first filter space and defines a third filter space in the first filter space, and the third filter space and the first filter space are isolated from each other in the radial direction; and / or the annular partition is arranged in the second filter space and defines a fourth filter space in the second filter space, and the second filter space and the fourth filter space are isolated from each other in the radial direction, which is not limited here.

[0044] Therefore, through the above-mentioned arrangement, multiple filter chambers can be isolated and distributed from each other in the axial and / or radial directions, making the layout of multiple filter chambers more compact, thereby reducing the volume of the filter housing and reducing the installation space of the dry cleaning device for installing the filter equipment 1, thereby reducing the volume of the dry cleaning device.

[0045] According to some embodiments of the present invention, Figure 3-Figure 4As shown, the filter housing includes: an outer cylinder 10, an end cover 20, a first partition plate 30 and a second partition plate 40. The end covers 20 are arranged at both ends of the outer cylinder 10 to close the outer cylinder 10. The first partition plate 30 is arranged in the outer cylinder 10 and divides the interior of the outer cylinder 10 into a first cavity and a second cavity isolated from each other in the axial direction.

[0047] It is worth mentioning that the second partition plate 40 may be arranged in the first cavity and define an inner cavity and an outer cavity in the first cavity. In this case, the inner cavity is configured as the third filter space, and the outer cavity is configured as the first filter space; the second partition plate 40 may be arranged in the second cavity and define an inner cavity and an outer cavity in the second cavity. In this case, the inner cavity is configured as the fourth filter space, and the outer cavity is configured as the second filter space; the second partition plate 40 may also be arranged in the first cavity and the second cavity, respectively, and the second partition plate 40 defines an inner cavity and an outer cavity in the first cavity and the second cavity, respectively, and no limitation is made here.

[0048] According to some embodiments of the present invention, Figure 3-Figure 4 As shown, the first partition plate 30 is provided with a first through hole connecting the first cavity with the second cavity, the second partition plate 40 is arranged in the first cavity, and the second cavity is connected with the inner cavity and the outer cavity respectively; the second partition plate 40 is arranged in the first cavity and is provided with a second through hole connecting the inner cavity and the outer cavity, and the second cavity is connected with the inner cavity or the outer cavity.

[0049] In some embodiments, the second partition plate 40 is disposed in the first cavity and defines an inner cavity and an outer cavity in the first cavity, the inner cavity and the outer cavity are radially isolated from each other, and the first partition plate 30 is formed with a plurality of first through holes that penetrate in the axial direction, and the axial projections of the plurality of first through holes are respectively located in the inner cavity and the outer cavity. At this time, the washing solvent can be discharged from the outlet 22 after passing through the outer cavity, the second cavity, and the inner cavity in sequence; or the washing solvent can be discharged from the outlet 22 after passing through the inner cavity, the second cavity, and the outer cavity in sequence, which is not limited here.

At this time, it can be that the washing solvent passes through the outer cavity, the inner cavity, and the second cavity in sequence and then is discharged from the outlet 22; it can be that the washing solvent passes through the inner cavity, the outer cavity, and the second cavity in sequence and then is discharged from the outlet 22; it can also be that the washing solvent passes through the second cavity, the inner cavity, and the outer cavity in sequence and then is discharged from the outlet 22; it can also be that the washing solvent passes through the second cavity, the outer cavity, and the inner cavity in sequence and then is discharged from the outlet 22, and it can also be that the washing solvent passes through the second cavity, the outer cavity, and the inner cavity in sequence and then is discharged from the outlet 22, and there is no limitation here.

[0051] According to some embodiments of the present invention, Figure 3-Figure 4 As shown, the outer cavity is provided with an annular first filter element 61 suitable for filtering the washing solvent entering the second cavity; the second cavity is provided with an annular second filter element 62 suitable for filtering the washing solvent entering the inner cavity, the inner cavity is connected to the outlet 22 and the inner cavity is provided with an annular third filter element 63 suitable for filtering the washing solvent passing through the outlet 22.

[0052] In some embodiments, the inlet 21 is connected to the outer cavity, and the outlet 22 is connected to the inner cavity. After the washing solvent enters the outer cavity from the inlet 21, the washing solvent passes through the first filter element 61 from one side and enters the other side of the first filter element 61. During the process of the washing solvent passing through the first filter element 61, the first filter element 61 can filter the stains mixed in the washing solvent to improve the cleanliness of the washing solvent. Subsequently, the washing solvent that has undergone preliminary filtration enters the second cavity. At this time, the washing solvent passes through the second filter element 62 from one side and enters the other side of the second filter element 62. During the process of the washing solvent passing through the second filter element 62, the second filter element 62 can filter the stains mixed in the washing solvent again. Then, the washing solvent enters the inner cavity. The washing solvent that enters the inner cavity passes through the third filter element 63 from one side and enters the other side of the third filter element 63. During the process of the washing solvent passing through the third filter element 63, the third filter element 63 can further filter the stains mixed in the washing solvent. Finally, the filtered washing solvent is discharged through the outlet 22.

[0053] According to some embodiments of the present invention, Figure 3-Figure 4 As shown, the inlet 21 and the outlet 22 are arranged at the same end of the filter housing on the axial side; or, the inlet 21 and the outlet 22 are respectively arranged at two ends of the filter housing on the axial direction.

[0054] In some embodiments, the inlet 21 and the outlet 22 are respectively arranged at the same end of the filter housing in the axial direction; in other embodiments, the inlet 21 and the outlet 22 are respectively arranged at both ends of the filter housing in the axial direction. Preferably, the inlet 21 and the outlet 22 are respectively arranged at the same end of the filter housing in the axial direction. It can be understood that the dry cleaning device also includes a washing device 2 and a solvent storage part 3, the inlet 21 is connected to the washing device 2 through a first connecting pipe, and the outlet 22 is connected to the solvent storage part 3 through a second connecting pipe. Therefore, the above arrangement can facilitate the first connecting pipe and the second connecting pipe to be connected to the inlet 21 and the outlet 22 respectively, thereby improving the assembly efficiency of the dry cleaning device.

[0055] According to some embodiments of the present invention, Figure 1-Figure 4 As shown, the filter device 1 further comprises: a pressure detection device 50, the pressure detection device 50 is provided with a detection end located in one of the filter cavities, and the detection end is suitable for detecting the pressure in the filter cavity.

[0056] In some embodiments, the pressure detection device 50 is provided with a detection end. Among the multiple filter cavities, one of the filter cavities is provided with a detection end. The detection end is suitable for detecting the pressure in the filter cavity. It is understandable that after the filter element is used for a long time, the filtering effect of the filter element will be reduced, and the efficiency of the washing solvent passing through the filter element will be reduced. When the filter element needs to be replaced, the efficiency of the washing solvent passing through the filter element is low and the washing solvent accumulates in the filter cavity. When the pressure in the filter cavity exceeds the preset value of the pressure detection device 50, the pressure detection device 50 can issue an alarm to prompt that the filter element needs to be replaced. Therefore, by setting the pressure detection device 50, the user can be prompted to replace the filter element in time to avoid the washing solvent passing through the filter element inefficiently and reduce the working efficiency of the dry cleaning device. At the same time, it can avoid excessive pressure in the filter cavity and damage to the filter device 1.
