Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only to distinguish the description, and are not to be construed as indicating or implying relative importance.

The present application provides a filter cleaning device for cleaning a processing apparatus provided with a filter. The treatment device equipped with the filter may be any of household or office treatment devices such as laundry treatment devices, air conditioners, purifiers, range hoods, air cleaners, dehumidifiers, and dust collectors.

In one embodiment of the present application, there is provided a laundry treatment apparatus for performing washing, rinsing, ironing, drying, etc. of laundry, the laundry treatment apparatus including a filter and a filter cleaning device as referred to in any one of the following embodiments. The laundry treatment apparatuses include, but are not limited to, laundry treatment apparatuses such as washing machines, dryers, washing and drying integrated machines, and the like. In fig. 1, a laundry treating apparatus 1000 is illustrated including a laundry accommodating device 1100 (which may be provided to include an inner tub and/or an outer tub), a drying device 2000, and an air outlet duct 1300 for accommodating laundry to be treated. The air outlet duct 1300 connects the laundry accommodating device 1100 and the drying device 2000. The air outlet duct 1300 is configured to guide an air flow from the laundry accommodating device 1100 to the drying device 2000. The relative positions of the laundry accommodating device 1100 and the drying device 2000 may be disposed opposite to each other up and down, or may be disposed opposite to each other back and forth, which is not limited in this application.

In one embodiment of the present application, the moisture flow in the laundry accommodating device 1100 enters the drying device 2000 after passing through the air outlet duct 1300, and the moisture flow enters the laundry accommodating device 1100 again after being dried by the drying device 2000 to form a circulating air flow between the laundry accommodating device 1100 and the drying device 2000.

In one embodiment of the present application, the drying device 2000 includes a moisture absorption unit and a moisture discharge unit. The moisture absorbing unit serves to absorb moisture in the air flow guided out from the laundry accommodation device 1100. The dehumidifying unit is used for discharging the moisture absorbed by the moisture absorbing unit so as to recover the dehumidifying capability of the moisture absorbing unit. A filter 601 is disposed between the air outlet of the laundry accommodation device 1100 and the air inlet of the drying device 2000 to filter the air flow. In one embodiment, a filter cleaning device 6200 is disposed on the non-filtering face of the filter 601 for cleaning the filter 601.

In one embodiment of the present application, the drying device 2000 includes: moisture absorption and removal turntable. The moisture absorption and removal turntable can rotate. The shell is used for accommodating the moisture absorption and removal turntable. The inner space of the case is partitioned into at least a moisture absorption space and a moisture discharge space. The moisture absorption and removal rotary table rotating to the moisture absorption space is used as a moisture absorption unit. The moisture absorption and removal rotary table rotating to the moisture removal space is used as a moisture removal unit.

In one embodiment of the present application, the drying device 2000 may include a moisture absorbing and discharging turntable on which a moisture absorbent for absorbing moisture is disposed, and a driving part driving the moisture absorbing and discharging turntable to rotate. The moisture absorbent can be zeolite, alkali aluminosilicate, lithium chloride, silica gel, modified silica gel, activated alumina, etc. In one embodiment, the moisture absorbent may also be a material with moisture absorption performance such as molecular sieves (including but not limited to zeolite molecular sieves, a/X/Y type molecular sieves, ZSM molecular sieves, beta molecular sieves, etc.), high molecular moisture absorbent, etc. The high molecular absorbent is also called as polymer absorbent, and has lower regeneration temperature than traditional silica gel, active carbon, molecular sieve absorbent and the like.

In one embodiment, the moisture absorbing and removing turntable may be made of porous materials such as zeolite, molecular sieve, metal-organic framework (Metal Organic Framework, MOF) materials, covalent organic framework materials (Covalent Organic Frameworks, COFs), nanocarbon, silica, and the like. In one embodiment, the moisture absorbing and removing turntable may be further formed by filling granular solid or particles made of at least one porous material as described above.

In an embodiment, the moisture absorbing and discharging turntable may be a honeycomb turntable or a corrugated turntable carrying a moisture absorbent, and can absorb and desorb absorbed water vapor so as to realize repeated desorption and regeneration. In one embodiment, the moisture absorbing and removing rotary disc comprises inorganic/organic fiber carriers (such as ceramics, glass fibers, MOFs, COFs, cordierite and the like), wherein the fiber carriers are coated with moisture absorbing agents such as molecular sieves and the like, and the molecular sieves are uniformly distributed among the fiber carriers and on the surfaces of the fiber carriers so as to realize the adsorption of air flow moisture. The molecular sieve may include a single-crystal molecular sieve or mixed-crystal molecular sieve such as A-type molecular sieve, X/Y-type molecular sieve, ZSM molecular sieve, beta molecular sieve, etc.

In one embodiment of the present application, the moisture absorbing and discharging rotary disc is divided into a moisture absorbing area and a regeneration area by the sealing system, and the moisture absorbing and discharging rotary disc slowly rotates under the drive of the driving part. When the moisture flow in the laundry accommodating device 1100 passes through the moisture absorption region of the moisture absorption and removal turntable, a portion of the moisture therein is absorbed by the moisture absorption medium in the turntable, and the drying air passing through the moisture absorption is introduced into the laundry accommodating device 1100 to dry the laundry therein. At the same time, the turntable gradually tends to saturate due to the absorption of a certain amount of moisture. In the regeneration zone of the moisture absorption and dehumidification rotary table, the other air can be changed into high-temperature air after passing through the heater and pass through the saturated rotary table after moisture absorption, so that the absorbed moisture in the rotary table is evaporated, and the dehumidification capability of the rotary table is recovered. In general, the wet air from the laundry accommodating apparatus 1100 may carry some foreign matters such as lint falling off from the laundry, but if the foreign matters such as lint are not filtered, the wet air may enter the drying apparatus 2000 and adhere to the moisture absorbing and discharging turntable, thereby blocking the moisture absorbing and discharging turntable, or the lint adhering to the moisture absorbing and discharging turntable may be ignited while passing through the heater, thereby damaging the moisture absorbing and discharging turntable.

Accordingly, in one embodiment of the present application, as shown in fig. 2, a filter 601 may be provided on a flow path of the humid air of the laundry accommodation device 1100 to filter foreign substances such as lint. For example, the filter 601 may be provided in the air outlet duct 1300 connecting the laundry accommodation device 1100 and the drying device 2000, and for example, the filter 601 may be provided in the air outlet duct 1300 to increase the filtering area of the filter 601. In the operation of the laundry treating apparatus, if the filter 601 is not cleaned for a long time, foreign matters such as lint attached thereto may block the air flow in the air outlet duct 1300, affecting the drying efficiency of the laundry treating apparatus.

In order to remove foreign substances such as lint from the filter 601, in one embodiment of the present application, a filter cleaning apparatus 6200 is provided for cleaning foreign substances attached to the filter 601. The filter cleaning device 6200 may be a spray device, through which cleaning liquid is sprayed to remove impurities attached to a filter.

The spray mechanism 6220 includes a water supply assembly 6230 and a spray assembly 6240. The water supply assembly 6230 is connected to the water supply port of the treatment apparatus through a water inlet 6231. The water supply assembly 6230 may include a flow directing structure for directing the cleaning fluid. The spray assembly 6240 is connected to the flow directing structure and the spray assembly 6240 has a plurality of spray ports 6241 spaced apart. The flow directing structure may direct the flow path of the cleaning fluid to the spray assembly 6240.

In this embodiment, a filter 601 may be disposed between the air outlet of the laundry accommodation device 1100 and the air inlet of the drying device 2000 to filter the air flow. A filter cleaning device 6200 may be provided on the non-filtering face side of the filter 601 for cleaning the filter 601. The drive mechanism 6210 is used in conjunction with the spray mechanism 6220 to facilitate the cleaning of the filter screen 601.

Further, as shown in fig. 3 and 4, in one embodiment, the spray mechanism 6220 includes a water supply assembly 6230 and a spray assembly 6240. Wherein the diversion structure is a water supply connector 6107 (which may be provided as a water supply hose) as shown in fig. 4. The water supply assembly 6230 further includes a water supply tube 6105. The water supply connector 6107 is connected to the water inlet 6231, and the water supply pipe 6105 is connected to the water supply connector 6107.

As shown in fig. 3, the drive mechanism 6210 includes a drive motor 6101 and a transmission, such as a gear box 6102 shown in fig. 3. The spray mechanism 6220 includes a spray header 6103 and a water supply pipe 6105. The showerhead 6103 may include one or more spray holes 6104 spaced apart. Such as: the showerhead 6103 may be similar in structure to a shower. The spraying holes 6104 may be arranged up and down row by row, and the spraying holes 6104 may be arranged left and right row by row. The shower holes 6104 may be provided in one or more rows, or may be provided in one or more columns. The shower holes 6104 may be regularly arranged, for example, the shower holes may be equally spaced, may be irregularly arranged, or may be randomly distributed according to a certain rule.

Fig. 5 illustrates a filter assembly (the filter assembly includes a filter 601, and the filter 601 is not directly shown in fig. 5 because fig. 5 is a partial cross-sectional view of the filter assembly) provided at an outer wall of the laundry accommodation device 1100, and a filter cleaning device 6200 for cleaning the filter 601. The drive motor 6101 and the gear box 6102 cooperate such that the spray mechanism 6220 is movable in a first direction (the length direction of the spray mechanism 6220) so that the cleaning fluid (the spray fluid, which may be water or water with a detergent added) is applied to both upper and lower ends of the filter 601 in the first direction. The spray mechanism 6220 may be rotated about an axis of rotation such that the spray fluid is applied to both the left and right ends of the filter 601 in a second direction.

In one embodiment, a specific configuration of the showerhead 6103 is illustrated in fig. 6. Fig. 6 (a) is a front view of the showerhead 6103, which is a front view of the showerhead 6103: the face of the showerhead 6103 facing the filter 601 (straight face filter 601) and fig. 6 (b) is a side view of the showerhead 6103. The movement distance of the spray mechanism 6220 in the first direction is greater than or equal to the shortest distance d3 between two adjacent spray holes 6104, so that the filter 601 can be directly sprayed by the spray fluid in the first direction, so as to ensure that the filter cleaning device 6200 can clean the filter 601 more comprehensively.

In one embodiment, the showerhead 6103 may be rotated to cause the sprayed fluid to cover the filter 601 in the second direction. In this embodiment, the rotation of the shower head 6103 can be driven by the driving motor 6101 and the gear case 6102, so that the shower holes 6104 rotate at a preset speed to remove the flocks and impurities attached to the filter 601.

The spray mechanism 6220 may be movable along the length of the spray mechanism 6220 such that the spray fluid covers the filter 601 in a first direction, the length of the spray mechanism 6220 being the first direction. The spray mechanism 6220 is rotated by a first angle about a first direction (the axis of rotation of the spray mechanism 6220 being parallel to the first direction) to expand the area of the spray fluid covering the filter 601. In one embodiment, as shown in FIG. 6 (c), the first angle α is 5-45. The direction from inside to outside and into the vertical paper surface in fig. 6 (c) is the first direction. Specifically, the first angle α may be set to 5 °, 12 °, 16 °, 19 °, 24 °, 28 °, 31 °, 37 °, 42 °, 45 °, or other angles. The rotation angle of the first angle α may be selected according to different widths of the filter 601. In this embodiment, the spray fluid covers more than 80% of the area of the filter 601 by movement of the spray mechanism 6220.

In one embodiment, the spray mechanism 6220 further comprises a switch for opening or closing one or more of the plurality of spray holes. The switch can control the opening or closing of the spray holes. The switch may be provided in an integrally formed structure, or may be provided in a plurality of intermittent structures. The spray mechanism 6220 comprises a first barrier 6106 as shown in fig. 6. The first blocking block 6106 is disposed on a surface of the showerhead 6103 away from the water supply pipe 6105 for blocking one or more of the plurality of spray holes 6104. The shower head 6103 has a cavity therein, and the first blocking block 6106 is disposed in the cavity so that the first blocking block 6106 can move up and down. The first blocking piece 6106 may be moved up and down in the first direction. In the practical application process of the clothes treating apparatus, the filter cleaning device 6200 may have a relative position of the spraying mechanism 6220 and the filter 601 set to the first position, that is, the spraying mechanism 6220 and the filter 601 are arranged at intervals in parallel in the first direction, and a specific parallel interval distance may be adjusted according to the different air outlet pipes 1300. With continued reference to fig. 6 (b), the first blocking block 6106 may first block some of the spray holes 6104 below, so that on one hand, the spray water pressure of the spray holes 6104 above may be made larger, so as to achieve the cleaning of the filter 601 above with the maximum effect; on the other hand, during the cleaning of the upper filter 601, part of the flock and impurities at the lower part of the filter 601 may be carried away by the filtered water. After the flock and impurities above the filter 601 are cleaned, the first blocking block 6106 is slowly moved down to expose more spray holes 6104, further washing the flock and impurities in the middle of the filter 601 and the lower portion of the filter 601. Eventually, the filter 601 can be cleaned with different water pressures. Specifically, the amount of spray holes 6104 (the amount of spray water), the speed of spray fluid in the spray holes 6104 (the speed of spray water), the pressure of spray fluid in the spray holes 6104 (the spray water pressure) may be controlled by providing a faucet/water valve.

In this embodiment, the amount of water sprayed, the speed of water sprayed, the water pressure sprayed and the angle of spraying can be adjusted by the spraying mechanism 6220, so that the cleaning effect of the spraying mechanism 6220 on the filter 601 is enhanced.
