Description

Technical Field

[0001] This application relates to a lint filter for use in a garment processing device in the field of household appliances, which removes lint from the drying air, and more particularly to a lint filter that can increase filtration efficiency. It also relates to a garment processing device with a garment drying function that is equipped with the above-mentioned lint filter. Background Technology

[0002] Many existing household laundry detergents include a drying function, allowing users to dry their clothes so they can be folded and stored or worn immediately. However, these devices typically dry clothes by blowing drying air into a drum containing the garments. But as the airflow passes over the clothes, lint and other fibers can mix with it, causing the lint to fly around and become a nuisance.

[0003] To eliminate the aforementioned problem, lint filters need to be installed on garment processing equipment. These filters utilize filter screens to trap lint in the drying airflow. However, existing lint filters on garment processing equipment are not effective in improving lint filtration efficiency.

[0004] To address the aforementioned issues, a method has been proposed that involves installing multi-stage filters to filter lint from the drying air. However, the aforementioned lint filters do not allow for easy cleaning of the multi-stage filters.

[0005] Based on the above problems, how to design a lint filter suitable for use in clothing drying equipment that can easily filter lint and efficiently clean the lint from the filter assembly has become an urgent technical challenge.

[0006] In view of the above, this application is hereby submitted. Summary of the Invention

Therefore, they should not be construed as limitations on this application.

[0035] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0036] like Figures 1 to 8 As shown in the embodiments of this application, a clothing processing device is introduced. This clothing processing device can be any existing device capable of drying clothing, such as a dryer, washer-dryer combo, or stackable clothing processing device. All clothing processing devices include a housing 200 with a clothing inlet for feeding clothing into a drum module inside the housing 200. The drum module then washes, dehydrates, and dries the clothing, thus achieving the desired processing effect. In this embodiment, a drum-type washer-dryer combo is used as an example. After the clothing processing device is placed on a support surface, the front side of the housing 200 facing the user is defined as follows: a clothing inlet is located on the front side of the housing 200; the axis of the drum module inside the housing 200 extends horizontally or slightly upwards at the opening; the opening of the drum module faces forward and is connected to the clothing inlet via a window pad, thus forming a channel for loading and unloading clothing. A door 100 is installed on the front panel of the housing 200. The door 100 can be installed on the housing 200 by means of sliding, hinge, etc., to correspond to the effect of opening or closing the clothing processing opening.

[0037] In this embodiment of the invention, to achieve drying of clothes inside the drum module, an air duct is generally installed inside the casing 200 of the clothing processing equipment. One end of the air duct 400 is connected to the outer drum of the drum module, and the other end is connected to the outside, forming a direct-vent drying equipment; alternatively, both ends of the air duct are connected to the outer drum of the drum module, and a condenser and evaporator of a heat pump system are installed on the air duct to form a circulating drying equipment. However, regardless of the form of the clothing processing equipment, a lint filter 300 needs to be installed on the air duct so that the drying airflow from the drum module passes through the lint filter, and the lint filter 300 filters the lint in the drying airflow. However, the lint filters installed on existing clothing processing equipment that filter lint in the drying air cannot effectively increase the ventilation volume, nor can the filter screen be cleaned conveniently and efficiently; in view of this, the specific method adopted in this embodiment is as follows:

[0038] like Figures 1 to 8 As shown in the figure, an embodiment of the present invention introduces a lint filter 300, including: an installation component 1 and a filter component, wherein a filter screen component 2 is installed on the installation component 1, so that the two together form a cylindrical filter cavity 3, so that the drying air flows into the cylindrical filter cavity 3 and is filtered and intercepted by the filter component before flowing out, thereby achieving the effect of filtering lint from the drying air.

[0039] In this embodiment of the invention, the filter assembly covers at least two adjacent radial sidewalls of the cylindrical filter cavity 3, so that the drying air flowing through the cylindrical filter cavity 3 can flow outward from the filter assembly in different radial directions, thereby increasing the filtration area of ​​the drying air and achieving a significant technical advancement in improving the filament filtration efficiency of the drying air.

[0040] In this embodiment of the invention, as shown in... Figure 1 As shown, the side of the filter assembly that is pulled outward relative to the mounting assembly 1 is the front side, and the side that is pushed inward is the rear side. Taking the side of the mounting assembly 1 relative to the filter assembly as the upper side and the side of the filter assembly relative to the mounting assembly 1 as the lower side, and taking the side of the filter assembly with the air outlet as the right side and the opposite side as the left side, the following discussion will elaborate on this example:

[0041] like Figures 1 to 8As shown, in this embodiment of the invention, an installation component 1 is mounted, and a filter assembly 2 is mounted on the installation component 1, together forming a cylindrical filter cavity 3. The filter assembly 2 covers at least two adjacent radial sidewalls of the cylindrical filter cavity 3. At least a portion of the adjacent sidewalls of the cylindrical filter cavity 3 are provided with air outlets 302. The filter assembly 2 has a filter screen covering the air outlets 302, so that the filter assembly 2 filters lint from the air outlets 302 on different sidewalls respectively, achieving the effect that the drying air flowing through the lint filter 300 exits from different radial sidewalls, thereby achieving a significant technical advancement in increasing the area of ​​the air outlet 302 of the lint filter 300 and improving the lint filtration efficiency.

[0042] In this embodiment of the invention, the axis of the cylindrical filter cavity 3 extends along a first direction, and the cross-section of the cylindrical filter cavity 3 in the first direction is square. In the first direction, one end of the cylindrical filter cavity 3 is open to form an air inlet 301, and the other end is closed. The air outlet 302 covers at least a portion of the horizontal side wall and the vertical lower side wall of the cylindrical filter cavity 3, so that the drying air flows into the cylindrical filter cavity 3 from the rear air inlet 301 and flows out after being filtered by the filter screen assembly 2 provided on the right and lower sides. This achieves the dispersion of the drying air in different radial directions, thereby achieving a significant technical advancement in increasing the air outlet area and improving the filtration efficiency of the filter assembly.

[0043] In this embodiment of the invention, the filter assembly 2 includes inner and outer double-layer filters; the inner part of the cylindrical filter cavity 3 is divided into a first part 303 and a second part 304 by the inner filter 201; the air inlet 301 of the cylindrical filter cavity 3 is connected to the first part 303, the second part 304 is connected to the air outlet 302 of the cylindrical filter cavity 3, and the outer filter 202 is laid at the air outlet 302.

[0044] In this embodiment of the invention, the air outlet 302 of the cylindrical filter cavity 3 covers at least a portion of the adjacent horizontal side and vertical lower side; the inner filter 201 and the mounting portion together form the first part 303; the inner filter 201 and the outer filter 202 are spaced apart to form the second part 304; the first part 303 is connected to the second part 304 via the inner filter 201, and the second part 304 is connected to the outside via the outer filter 202.

[0045] In this embodiment of the invention, the mounting assembly 1 includes a mounting top plate 101, and the front and rear sides of the mounting top plate 101 are respectively provided with a front mounting frame 102 and a rear mounting frame 103 extending vertically downward; the filter assembly 2 includes a filter frame, which is a grooved grid structure formed by cross-arranged horizontal and vertical beams. The upper end of the grooved grid structure is open, and the mounting top plate 101 is fastened to the upper side of the grooved grid structure. The front and rear sides of the grooved grid structure are correspondingly supported on the front mounting frame 102 and the rear mounting frame 103 on the corresponding sides.

[0046] In this embodiment of the invention, the filter frame includes an inner frame 211 and an outer frame 221; the inner filter 201 is laid on the inner frame 211, and the outer filter 202 is laid on the outer frame 221; the front sides of the inner frame 211 and the outer frame 221 are connected to the handle 203, and the handle 203 correspondingly covers and seals the front side of the filter frame; the rear side of the inner frame 211 is in communication with the air inlet 301 formed by the rear mounting frame 103, and the rear side of the outer frame 221 is correspondingly covered and sealed by the rear mounting frame. Optionally, the rear side of the inner frame 211 is connected to the rear side of the outer frame 221 via a stop 204. The stop 204 covers and seals the rear side of the interlayer space between the inner and outer filters 201 and 202. At least a portion of the stop 204 is staggered with the scraper assembly 4 on the front side to prevent the filter assembly 2 from moving too much relative to the mounting assembly 1 and causing it to fall off.

[0047] In this embodiment of the invention, the left or right side of the outer frame 221 is covered with a windbreak portion 223 formed by a sealing plate; the windbreak portion 223 correspondingly closes the corresponding side of the outer frame 221. Optionally, the left side of the outer frame 221 is provided with a windbreak portion 223, and the right and lower sides are provided with outer filter screens 202, so that the drying air entering the cylindrical filter chamber 3 can flow out from the lower and right sides, and be filtered sequentially by the inner filter screen 201 and the outer filter screen 202, thereby achieving the effect of sequentially filtering and intercepting lint from the drying air.

[0048] In addition, in order to improve the lint interception efficiency, the mesh size of the inner filter 201 can be set to be smaller than that of the outer filter 202, so that smaller lint can be filtered and intercepted by the downstream outer filter 202, thereby reducing the lint accumulated on the inner filter 201, improving the airflow permeability of the inner filter 201, and further improving the significant technological progress of the double-layer filter assembly 2 in filtering lint from the drying air.

[0049] In this embodiment of the invention, the filter assembly 2 is installed on the mounting assembly 1 in a pull-back manner; the mounting assembly 1 and / or the filter assembly 2 are provided with a handle 203 for the user to hold. Specifically, the handle 203 can be configured as follows: In this embodiment, the mounting assembly 1 has a mounting top plate 101 on its upper side, and the upper side of the mounting top plate 101 has a downwardly recessed first handle groove 104; the filter assembly 2 has a handle 203 on its front side, and the front side of the handle 203 has a rearwardly recessed second handle groove. Alternatively, the front side of the handle 203 can be made into a smooth plane so that the lint filter 300 forms a smooth and flat front surface after being pushed into the garment processing device; and a handle or similar structure can be provided on the lower or upper side, left or right side of the handle 203 to form a second handle groove, which can also achieve the effect of pulling the filter assembly 2.

[0050] Furthermore, the existing lint filter 300 installed on garment processing equipment, which filters lint from the drying air, cannot be easily and efficiently cleaned; in particular, there is no existing technical solution for easily cleaning the inner and outer double-layer filter screens of the lint filter 300. In view of this, the specific method adopted in the embodiments of this application is as follows:

[0051] like Figures 1 to 8 As shown in the illustration, an embodiment of the present invention introduces a lint filter 300, which includes: an installation component 1, on which a filter screen component 2 is retractably installed, forming a cylindrical filter chamber 3; the filter screen component 2 includes inner and outer double-layer filter screens, through which drying air flows sequentially to achieve the effect of filtering and intercepting lint in stages; simultaneously, a scraper component 4 is provided on the installation component 1 for cleaning the lint from the inner and outer filter screens 202 of the retracted filter screen component 2. Through the above configuration, the inner and outer filter screens 202 of the filter screen component 2 can be simultaneously cleaned of lint by the scraper component 4, achieving the effect of cleaning different filter screens separately using a single scraper component 4, thus achieving a significant technological advancement in convenient and efficient cleaning of lint from the inner and outer double-layer filter screen component 2.

[0052] In this embodiment of the invention, the double-layer filter assembly 2 includes an inner filter 201 and an outer filter 202 arranged at intervals; the double-layer filter assembly 2 is pulled out from the front side of the mounting assembly 1; the scraper assembly 4 is disposed at the front side of the mounting assembly 1 and is used to simultaneously scrape off the lint from the inner filter 201 and the outer filter 202 during the pulling and moving process.

[0053] In this embodiment of the invention, the scraper assembly 4 includes a first scraper 401; the first scraper 401 is located between the inner filter 201 and the outer filter 202, and the two opposite sides of the first scraper 401 respectively clean the opposite sides of the inner filter 201 and the outer filter 202; that is, the first scraper 401 cleans and scrapes the outer side of the inner filter 201 with the inner peripheral side facing the inside of the cylindrical filter cavity 3, and the first scraper 401 cleans and scrapes the inner side of the outer filter 202 with the outer peripheral side facing the outside of the cylindrical filter cavity 3.

[0054] In this embodiment of the invention, the scraper assembly 4 includes a second scraper 402; the second scraper 402 is located inside the inner filter screen 201, and the outer peripheral side of the second scraper 402 cleans the inner peripheral side of the inner filter screen 201 of lint; that is, the second scraper 402 cleans and scrapes the inner surface of the inner filter screen 201 of lint towards the outer peripheral side of the cylindrical filter cavity 3.

[0055] In this embodiment of the invention, the front end of the cylindrical filter chamber 3 is a closed handle 203, the rear end is an air inlet 301, and the side wall is provided with an air outlet 302; the double-layer filter assembly 2 at least covers the air outlet 302, the air inlet 301 is connected to the space surrounded by the inner layer filter 201 of the double-layer filter assembly 2, and the interlayer space between the inner layer filter 201 and the outer layer filter 202 is connected to the air inlet 301 and the air outlet 302 respectively through the inner layer filter 201 and the outer layer filter 202.

[0056] In this embodiment of the invention, the mounting assembly 1 includes a mounting top plate 101, the lower side of which is slidably connected to the upper ends of the inner filter 201 and the outer filter 202 respectively; a scraper assembly 4 is provided on the front side of the mounting top plate 101, the scraper assembly 4 has a gap, and the double-layer filter assembly 2 passes through the gap; a handle 203 is installed at the front end of the double-layer filter assembly 2, the handle 203 is located in front of the scraper assembly 4, and is used for the user to pull the double-layer filter assembly 2 outward; a stop 204 is installed at the rear end of the double-layer filter assembly 2, the stop 204 at least partially intersects with the scraper assembly 4, and is used to restrict the double-layer filter assembly 2 from detaching from the mounting assembly 1. Optionally, to improve the scraping effect, a scraper made of elastic material such as rubber can be provided on the scraper assembly 4. The scraper forms a gap through which the inner filter 201 and outer filter 202 of the filter assembly 2 pass, so that the end of the scraper can fit in contact with the side wall of the corresponding filter, thereby achieving a significant technical advancement in effectively cleaning the filter and improving the scraping efficiency of the lint.

[0057] In this embodiment of the invention, the inner filter 201 has horizontally protruding inner sliding portions 212 on the upper ends of its left and right sides facing each other; the outer filter 202 has horizontally protruding outer sliding portions 222 on the upper ends of its left and right sides facing each other; the scraper assembly 4 has sliding grooves for the inner sliding portions 212 and the outer sliding portions 222 to be inserted into, respectively, to guide the double-layer filter assembly 2 to slide horizontally back and forth. In particular, by using the horizontally protruding sliding portions with different orientations on the inner and outer filter 202, the stability of the entire horizontal pulling process of the double-layer filter assembly 2 is improved, effectively avoiding problems such as left-right or up-down tilting during the pulling process of the filter assembly 2.

[0058] In this embodiment of the invention, the inner and outer filter layers 202 of the dual-layer filter assembly 2 at least cover the lower and right sides of the lint filter 300, guiding airflow from the air outlets 302 located on different side walls. Simultaneously, to avoid interference between the lint filter 300 and other components, rounded chamfers can be provided at the lower left and lower right corners of the dual-layer filter to improve safety; furthermore, the air outlets 302 on both sides can be directly connected to form a single air outlet 302 to further improve the convenience of air filtration.

[0059] Furthermore, in this embodiment of the invention, the filter frame includes an inner frame 211 and an outer frame 221; the inner filter 201 is laid on the inner frame 211, and the outer filter 202 is laid on the outer frame 221; the front sides of the inner frame 211 and the outer frame 221 are connected to the handle portion 203, and the handle portion 203 correspondingly covers and blocks the front side of the filter frame; the rear side of the inner frame 211 is in relative communication with the air inlet 301 formed by the rear mounting frame 103, and the rear side of the outer frame 221 is correspondingly covered and blocked by the rear mounting frame. Optionally, the rear side of the inner frame 211 is connected to the rear side of the outer frame 221 via a stop 204. The stop 204 covers and seals the rear side of the space between the inner and outer filters 201 and 202. At least a portion of the stop 204 is staggered with the front scraper assembly 4 to prevent the filter assembly 2 from moving too much and falling off when it is pulled forward relative to the mounting assembly 1. In order to clean and discharge the lint scraped off the filter assembly 2 by the scraper assembly 4, the stop 204 can be detachably installed on the filter frame, and / or an openable and closable door can be provided on the stop 204. The scraper assembly 4 scrapes off the filter assembly 2 and collects the lint between the stop 204 and the scraper assembly 4 using the detached stop 204 or the open door, and then dumps it out for cleaning.

[0060] like Figures 1 to 8As shown in the embodiment of the present invention, a clothing processing device is also introduced, which includes: an air duct 400, wherein the air duct 400 is provided, and when the air duct 400 is working, an airflow is formed in the air duct 400 from the air inlet end to the air outlet end; a lint filter 300 as described above is installed in the air duct 400, the air inlet of the lint filter 300 is connected to the bottom side of the outer cylinder through an air inlet hose, and the air outlet of the lint filter is connected to the cylinder opening side of the outer cylinder through the air duct 400 to form a drying air circulation path, and the filter screen assembly of the lint filter filters and intercepts lint from the circulating drying air, so as to achieve the effect of filtering and intercepting lint generated by the clothes to be dried in the outer cylinder.

[0061] In this embodiment of the invention, an installation cavity is provided in the air duct 400, and the lint filter 300 can be installed in the installation cavity by being pulled back and forth. An inclined surface is provided on the lower side of the installation cavity, and the right side of the installation cavity is connected to the air duct 400, so that the right air outlet 302 of the cylindrical filter cavity 3 of the lint filter 300 can be directly connected to the air duct 400, and the lower air outlet 302 is indirectly connected to the air duct 400 by being guided by the inclined surface. This achieves the effect that the air outlets 302 of the lint filter 300 with different radial orientations can all be used to allow the drying airflow after lint filtration to flow into the air duct 400, achieving a significant technical advancement in improving the lint filtration efficiency of the drying airflow.

[0062] In this embodiment, both the inner filter 201 and the outer filter 202 of the filter assembly 2 have a perimeter frame, and a layer of filter mesh is laid on the side of the perimeter facing the inside of the cylindrical filter cavity 3. The filter frame can be made of rigid materials such as metal or plastic to form a supporting frame structure for the filter. To improve the structural strength of the filter assembly 2, horizontal and vertical beams can be arranged intersectingly within the frame to form a grid-like frame structure. The filter mesh laid on the frame can be composed of a filter structure with a certain mesh size, and can be formed by interlacing threads, wires, etc. Therefore, in this embodiment, the upper, lower, front, rear, left, and right sides of the inner filter 201 and the outer filter 202 are all portions of the corresponding sides of the outer perimeter frame of the filter.

[0063] In this embodiment, the middle part of the mounting top plate 101 of the mounting assembly 1 and the corresponding upper side of the filter assembly 2 are all set as transparent observation sections. These transparent observation sections can be independent components, fixedly mounted, or integrally embedded in the mounting top plate 101, and are made of transparent materials such as plastic or glass, allowing users to directly observe the accumulation of lint below through the transparent observation sections. Alternatively, the entire mounting top plate 101 can be made of transparent material, making the entire mounting top plate 101 a transparent observation section, etc. This allows users to directly observe the inner circumference of the filter assembly 2 through the transparent observation sections provided on the mounting assembly after removing the lint filter 300, effectively obtaining the amount of lint accumulated by the filter assembly, thus achieving a significant technological advancement in timely and effective cleaning of the filter assembly 2.

[0064] Furthermore, in this embodiment, the mounting top plate 101 of the mounting assembly 1 is located at the uppermost side of the lint filter 300 that is pulled out along the front and rear directions. Multiple reinforcing ribs are arranged on the upper side of the mounting top plate 101, and the upper end face of each reinforcing rib abuts against the inner top wall of the mounting cavity of the air duct 400, so that the middle part of the mounting top plate 101, which is composed of the entire plate, can be structurally reinforced, and each part of the mounting top can be respectively limited and abutted downward to prevent the excessive air pressure inside the cylindrical filter cavity 3 from causing the upper mounting top plate 101 to deform upward.
