Description

Technical Field

[0001] The present application belongs to the technical field of clothing processing equipment, and in particular relates to a lint filter box and clothing processing equipment. Background Art

[0002] The drying principle of the heat pump dryer is as follows: the hot and humid air in the drying barrel enters the condenser for heat exchange under the action of the fan, obtaining dry air with a lower temperature, which is then heated through the drying tunnel to become high-temperature dry air and then returns to the drying barrel, thereby drying the clothes in the barrel. As the moisture in the clothes evaporates, the high-temperature dry air becomes hot and humid air again and starts the next cycle.

[0003] During the drying process, lint from clothes inside the drum can circulate with the air and enter the folds of the door seal, making it difficult to clean and prone to bacterial growth. Furthermore, lint can easily become entangled in the heating element as it passes through the drying duct. The high temperatures of the heating element can cause the lint to burn, posing a safety risk. Some existing dryers incorporate filters within the drying duct to filter out lint from the air. To ensure effective filtration, the filter must be cleaned regularly. However, the cylindrical filter, due to its shape, makes cleaning more difficult, impacting the user experience.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0040] The embodiment of the present application provides a lint filter box, which can be applied to a clothes processing device, which can be a clothes dryer or a washer-dryer. Figure 1-Figure 3 , Figure 1 This is a schematic diagram of the structure of the lint filter box provided in the embodiment of the present application. Figure 2 for Figure 1 A cross-sectional view of the lint filter box is shown, Figure 3 for Figure 1 The lint filter box 100 comprises a box body 110 , a filter cartridge 120 and a scraping assembly 130 .

[0041] Among them, the box body 110 is provided with an air inlet 111 and an air outlet 112; the filter cartridge 120 has a cartridge opening 121, the filter cartridge 120 is suitable for extending into the box body 110, and is connected with the air inlet 111 through the cartridge opening 121, and the air flowing into the filter cartridge 120 from the air inlet 111 flows out from the air outlet 112 after being filtered; the scraping assembly 130 includes an annular scraping piece 131 arranged in the filter cartridge 120, and the circumferential inner wall of the filter cartridge 120 is sleeved on the outer periphery of the annular scraping piece 131, and the annular scraping piece 131 is suitable for moving along the length direction H1 of the filter cartridge 120 to scrape off the fluff on the filter cartridge 120.

[0042] It should be noted that the air flowing into the air inlet 111 carries substances such as fluff and dust. After the air flows through the filter cartridge 120, the fluff and dust it carries are left on the filter surface inside the filter cartridge 120. The scraping assembly 130 is conformally matched with the circumferential inner wall of the filter cartridge 120, so that the annular scraper 131 can efficiently scrape off the fluff around the circumferential inner wall. Preferably, the filter cartridge 120 is cylindrical, and correspondingly, the annular scraper 131 is annular, and the outer periphery of the annular scraper 131 abuts against the circumferential inner wall of the filter cartridge 120. In some other embodiments, the filter cartridge 120 can also be prismatic, and the shape of the annular scraper 131 is adapted to the shape of the filter cartridge 120.

[0043] In some embodiments, the annular scraper 131 includes an annular support portion and bristles disposed on the outer peripheral sidewall of the annular support portion. The bristles are adapted to brush the circumferential inner wall of the filter cartridge 120 to remove lint and hair debris adhering to the circumferential inner wall of the filter cartridge 120. The material and arrangement of the bristles are selected by the designer based on actual needs. Alternatively, the bristles can be made of plastic, silicone, or the like, and can be densely distributed in an array along the entire outer peripheral sidewall of the annular support portion.

[0044] The lint filter box 100 provided in the embodiment of the present application uses a filter cartridge 120 to filter lint, has a larger filtration area, and thus improves the filtration efficiency. In addition, by adding a scraping assembly 130 to scrape off the lint on the filter cartridge 120, on the one hand, it can be convenient for the user to clean the filter cartridge 120. On the other hand, the annular scraper 131 is used for scraping, which is simple to operate and can improve the cleaning efficiency and effect of the lint.

[0045] In some embodiments, the filter cartridge 120 defines a guide hole 122, and the scraper assembly 130 further includes a pull-out member 132. One end of the pull-out member 132 is connected to the annular scraper 131, while the other end extends through the guide hole 122 and is partially located outside the filter cartridge 120. The pull-out member 132 is adapted to be pulled by an external force to drive the annular scraper 131 to move along the length of the filter cartridge 120. This further improves the user's convenience in cleaning the filter cartridge 120. The pull-out member 132 and the annular scraper 131 can be integrally formed, and the pull-out member 132 can be made of plastic, metal, or other non-deformable material.

[0046] In actual application, when the user needs to clean the filter cartridge 120, the user pulls the part of the pull-out member 132 located outside the filter cartridge 120 to drive the annular scraper 131 to move along the length direction of the filter cartridge 120, so that the annular scraper 131 can scrape off the fluff on the filter cartridge 120. The user can then remove the scraped fluff from the filter cartridge 120 to achieve cleaning.

[0047] In some embodiments, see Figure 4-Figure 5 , Figure 4 This is a schematic diagram of the structure of the scraping assembly provided in the embodiment of the present application installed on the filter cartridge. Figure 5 for Figure 4 The filter cartridge 120 includes a first end 120a and a second end 120b that are opposite to each other in the longitudinal direction H1. The scraper assembly 130 also includes an elastic member 133, one end of which is connected to the annular scraper 131 and the other end is connected to the filter cartridge 120. When the pull member 132 is driven by an external force to move the annular scraper 131 from the first end 120a toward the second end 120b, the elastic member 133 is elastically deformed. When the external force disappears, the elastic member 133 returns to its original shape, driving the annular scraper 131 to move from the second end 120b toward the first end 120a.

[0048] It is understood that the user can pull the pull-out member 132 to move the annular scraper 131 from the first end 120a of the filter cartridge 120 toward the second end 120b, thereby scraping off the lint on the filter cartridge 120. After the user releases the pull-out member 132, the elastic member 133 will return to its original shape and pull the annular scraper 131 back to the first end 120a of the filter cartridge 120. In this way, the user does not need to manually return the annular scraper 131 to its original position, further improving the convenience of cleaning the filter cartridge 120 and enhancing the user experience.

[0049] In an optional embodiment, the filter cartridge 120 includes a bottom wall 123 disposed near the second end 120 b thereof in the length direction H1 , the guide hole 122 is opened in the bottom wall 123 , and the elastic member 133 is connected to the bottom wall 123 .

[0050] The extending direction of the guide hole 122 may be the same as the length direction H1 of the filter cartridge 120. Figure 4 When the elastic member 133 is in a normal state, the annular scraping member 131 is located in the filter cartridge 120 near the first end 120a thereof, and the pull-out member 132 extends from the first end 120a to the second end 120b inside the filter cartridge 120 and extends out of the filter cartridge 120 through the guide hole 122 on the bottom wall 123. That is, at this time, the pull-out member 132 is partially received inside the filter cartridge 120; see Figure 5 When cleaning the filter cartridge 120, the portion of the drawer 132 that is stored is pulled out through the guide hole 122, thereby driving the annular scraper 131 to move to the second end 120b. This reduces the space outside the filter cartridge 120 occupied by the drawer 132, thereby reducing the space required by the entire lint filter box 100.

[0051] In another optional embodiment, the guide hole 122 may be formed on the circumferential sidewall of the filter cartridge 120. For example, the guide hole 122 is a strip-shaped hole, and its length direction is the same as the length direction H1 of the filter cartridge 120, thereby guiding the movement of the pull-out member 132 so that the annular scraping member 131 moves along the length direction of the filter cartridge 120.

[0052] In some embodiments, see Figure 6 , Figure 6 Schematic diagram of the structure of the scraper assembly provided in an embodiment of the present application. The pull-out member 132 includes a pull rod 1321 and a handle 1322. The handle 1322 is disposed outside the filter cartridge 120. One end of the pull rod 1321 is connected to the annular scraper 131, and the other end is passed through the guide hole 122 and connected to the handle 1322.

[0053] It can be understood that the handle 1322 is suitable for the user to hold tightly with his hand so as to facilitate pulling the pull rod 1321. Exemplarily, the handle 1322 is a pull ring. Exemplarily, a connecting bracket 134 is provided on the inner ring side wall of the annular scraper 131, and one end of the pull rod 1321 is connected to the annular scraper 131 through the connecting bracket 134. Preferably, the annular scraper 131 is in the shape of a circular ring, and the geometric center of the annular scraper 131 at least falls on the extension line where the pull rod 1321 is located. For example, the annular scraper 131 in the shape of a circular ring includes a first end and a second end that are symmetrical with respect to the diameter, the connecting bracket 134 is a linear bracket, and the two ends are respectively connected to the first end and the second end of the annular scraper 131, and one end of the pull rod 1321 is connected to the middle position on the connecting bracket 134.

[0054] Optionally, the elastic member 133 comprises a spring, which is sleeved on the pull rod 1321 and has its ends connected to the annular scraper 131 and the bottom wall 123, respectively. One end of the spring may also be connected to the connecting bracket 134. When the annular scraper 131 moves from the first end 120a toward the second end 120b of the filter cartridge 120, the spring is compressed. When the external force acting on the pull member 132 disappears, the spring recovers its length, driving the annular scraper 131 from the second end 120b toward the first end 120a.

[0055] For further information, see Figure 7 , Figure 7 An exploded view of a filter cartridge provided in an embodiment of the present application. Filter cartridge 120 includes a body 124 and a filter screen 125. One end of body 124 is open to form a port 121, while the other end is closed to form a bottom wall 123. A filter port 126 is defined in the sidewall of body 124. Filter screen 125 is disposed within body 124 and covers at least filter port 126.

[0056] Optionally, there are multiple filter ports 126, each of which is a square opening and spaced apart along the circumference of the cylinder 124. To increase the filtration area of the filter cartridge 120, the filter ports 126 can be opened as large as possible to increase the filtration area while ensuring the support performance of the cylinder 124. The cylinder 124 can be made of plastic material.

[0057] Optionally, the filter 125 is an annular filter that conforms to the sidewall of the barrel 124. The filter 125 can be adhered to the inner wall of the barrel 124, or an annular retaining groove can be provided on the inner wall of the barrel 124, with the annular filter 125 being retained in the retaining groove. In other embodiments, the filter 125 can be a sheet-like filter, with multiple sheets provided, with at least one sheet of filter 125 covering each filter opening 126.

[0058] In some embodiments, see Figure 3 The box body 110 is further provided with an installation opening 113, through which the filter cartridge 120 can be inserted into or pulled out of the box body 110. In this way, when the user needs to clean the filter cartridge 120, the filter cartridge 120 can be pulled out of the box body 110 for cleaning.

[0059] The filter cartridge 120 further includes a mounting base 127, which allows the filter cartridge 120 to be removably mounted to the housing 110. In practice, after inserting the filter cartridge 120 into the housing 110, the user can connect the mounting base 127 to the housing 110 to securely mount the filter cartridge 120 thereto. The user can also remove the mounting base 127 from the housing 110 to remove the filter cartridge 120 from the housing 110 for cleaning. Optionally, the mounting base 127 is disposed on a side of the bottom wall 123 facing away from the first end 120a.

[0060] In some embodiments, the mounting base 127 is further adapted to block the mounting opening 113. In this way, air leakage from the mounting opening 113 can be avoided. Exemplarily, a threaded groove is provided on the inner wall of the box body 110 for forming the mounting opening 113, and a threaded portion is correspondingly provided on the outer peripheral side wall of the mounting base 127. The threaded portion is screwed into the threaded groove, so that the mounting base 127 is mounted on the box body 110 and blocks the mounting opening 113. To facilitate the user's disassembly and assembly of the filter cartridge 120, a knob portion may be further provided on the surface of the mounting base 127 facing away from the box body 110. The knob portion is adapted for the user to rotate so that the mounting base 127 is screwed into or removed from the box body 110. In other embodiments, the mounting base 127 may be configured as a piston that conforms to the mounting opening 113.

[0061] In order to reduce the overall volume of the lint filter box 100, the box body 110 can be set to a cylindrical shape that matches the shape of the filter cartridge 120, and the box body 110 is sleeved on the outer periphery of the filter cartridge 120; the air inlet 111 is opened at one end of the box body 110 in the length direction, the installation port 113 is opened at the other end of the box body 110 in the length direction, and the air outlet 112 is opened on the side wall of the box body 110.

[0062] The lint filter box 100 provided in the embodiment of the present application uses a filter cartridge 120 to filter lint, has a larger filtration area, and thus improves the filtration efficiency. In addition, by adding a scraping assembly 130 to scrape off the lint on the filter cartridge 120, on the one hand, it can be convenient for the user to clean the filter cartridge 120. On the other hand, the annular scraper 131 is used for scraping, which is simple to operate and can improve the cleaning efficiency and effect of the lint.

[0063] The present application also provides a clothes processing device, for example, see Figure 8 , Figure 8 Schematic diagram of the structure of the clothing processing device provided in an embodiment of the present application.
