Description

Technical Field

[0001] This application relates to the field of clothing washing and care technology, and in particular to a clothing processing device. Background Technology

[0002] Taking a clothes dryer as an example, during the use of a clothes dryer, it is inevitable that some fiber tissue or other substances naturally adhering to the outer layer of the clothes, such as dust and human hair, will fall off. These will then form lint that is intercepted by the filter screen in the air duct as the air flows. However, when pet hair such as cat or dog hair is adhering to the outer layer of the clothes, even the high-mesh filter screens currently on the market are difficult to intercept. The filtration and interception of pet hair has become a problem that urgently needs to be solved. Summary of the Invention

[0016] In some implementations, the first support frame unit abuts against the filter structure in a direction away from the first filter cavity, so that the filter structure is positioned on the outer periphery of the support frame unit based on the frictional force generated by the abutment.

[0017] In some implementations, the support frame unit includes a first support frame and a second support frame, the first support frame and the second support frame being arranged along the airflow direction, and the filter structure being located between the first support frame and the second support frame.

It is also beneficial for intercepting pet hair mixed in the airflow. In addition, the three-dimensional fiber structure has a large dust holding capacity and a longer lifespan. Furthermore, the pressure drop increases more slowly with the accumulation of particles, meaning the increase in air resistance is slower. This helps to extend the filtration time, for example, by using it for 10 drying cycles before cleaning or replacement. Attached Figure Description

[0028] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0029] This application provides a garment processing device, including a bobbin assembly and an air duct.

[0030] The tube assembly has a garment handling chamber for holding garments. In some embodiments, the tube assembly is a vertical axis type, meaning the opening of the garment handling chamber faces upwards, and the user places garments into the garment handling chamber from above. In other embodiments, the tube assembly is a horizontal axis type, meaning the opening of the garment handling chamber faces directly forward or diagonally forward, and the user places garments into the garment handling chamber from the front.

[0031] Clothing handling equipment can be a dryer, a washer-dryer combo (i.e., washing and drying are performed separately in the same clothing handling chamber), or a washer-dryer suite (i.e., the same equipment integrates washing and drying functions, with washing performed in one clothing handling chamber and drying performed in another clothing handling chamber).

[0032] The air duct is connected to the garment processing chamber. Airflow from the garment processing chamber is discharged into the air duct. In some embodiments, the airflow discharged from the air duct is directed to an indoor or outdoor space; in this embodiment, the airflow discharge method can also be referred to as direct exhaust. In other embodiments, the end of the air duct is connected to the garment processing chamber, i.e., the air duct and the garment processing chamber form a circulation path, and the airflow circulates within the garment processing chamber and the air duct.

[0033] In some embodiments, please refer to Figure 1 and Figure 2 The garment processing equipment includes a housing 10, and a cylindrical assembly is disposed inside the housing 10.

[0034] In some embodiments, please refer to Figure 1 The housing 10 includes a left side panel and a right side panel 13, which are arranged at intervals along the left and right directions of the garment processing equipment.

[0035] In some embodiments, please refer to Figure 1 and Figure 2 The housing 10 includes a front panel 11. The two ends of the front panel 11 are connected to the left side panel and the right side panel 13. The front panel 11 serves as the exterior component of the garment handling equipment.

[0036] In some embodiments, please refer to Figure 1 The housing 10 includes a top cover 12, which connects the top of the left side panel and the top of the right side panel 13.

[0037] In some embodiments, the air duct has a condensation dehumidification structure and a heating structure. The condensation dehumidification structure is used to condense and dehumidify the airflow. The heating structure is used to heat the airflow and guide the heated airflow into the clothing processing chamber, thereby using the hot airflow to dry the clothes.

[0038] In some embodiments, please refer to Figure 4 , Figure 5 , Figure 6 The garment processing equipment also includes a filter structure 20. The filter structure 20 is located in the air duct and is used to filter the airflow entering the air duct from the garment processing chamber. The filter structure 20 is a three-dimensional random fiber web. That is, the filter structure 20 has no warp or weft threads; it is not a woven structure. The fiber arrangement is random and irregular, forming a three-dimensional, fluffy mesh. This allows it to capture tiny particles with high interception efficiency, facilitating high-precision filtration and effectively intercepting pet hair mixed in the airflow. Furthermore, the three-dimensional fiber structure has a large dust holding capacity and a longer lifespan. The pressure drop increases more slowly with particle accumulation, meaning the increase in air resistance is slower, which helps extend the filtration time; for example, it can be cleaned or replaced after 10 drying cycles. In existing technologies, the filter structure uses a two-dimensional planar woven mesh. Woven mesh has the drawback of only being able to perform surface coarse filtration. The pore shape of the woven mesh is regular and the pore size is uniform, which can only intercept large particles on the surface. It has poor filtration efficiency for fine lint, pet hair and other impurities. In addition, the woven mesh has a two-dimensional straight-through pore structure with a small dust holding capacity. Impurities can easily and quickly clog the mesh, resulting in a sharp increase in airflow resistance and a sharp decrease in filtration efficiency.

[0039] In some embodiments, the area mass of the three-dimensional random fiber filter is 10 g / m²–90 g / m² (grams per square meter). For example, values ​​such as 10 g / m², 15 g / m², 20 g / m², 25 g / m², 30 g / m², 33 g / m², 38 g / m², 40 g / m², 46 g / m², 50 g / m², 54 g / m², 60 g / m², 63 g / m², 70 g / m², 75 g / m², 80 g / m², 87 g / m², and 90 g / m², as well as any value between two adjacent values, are used. It should be noted that a higher area mass value indicates more fiber accumulation and higher filtration efficiency, but also higher air resistance; a lower area mass value indicates less fiber accumulation and lower filtration efficiency, but lower air resistance. This embodiment's range balances the filtration efficiency and air resistance of the filter structure 20. In some specific embodiments, the mass per unit area of ​​the three-dimensional random fiber filter is 25 g / m²–75 g / m². This range allows for a better balance between the filtration efficiency and air resistance of the filter structure 20.

[0040] In some embodiments, the thickness of the three-dimensional random fiber filter is 0.1mm-0.5mm. For example, values ​​such as 0.1mm, 0.2mm, 0.3mm, 0.4mm, and 0.5mm, as well as any value between two adjacent values. It should be noted that a thicker filter results in greater air resistance, but also better filtration efficiency. The thickness range in this embodiment is beneficial for balancing filtration efficiency and air resistance.

[0041] The material of the three-dimensional random fiber filter is not limited. For example, it can be polypropylene, polyester PET (polyethylene terephthalate), or bicomponent PET. Among them, bicomponent PET is made by making two different types of PET into a composite fiber, which combines the advantages of the two materials: strength, elasticity, softness, fluffiness, and good adhesion.

[0042] In some embodiments, please refer to Figure 8 and Figure 9 The filter structure 20 is formed by three-dimensional random fiber mesh enclosing an interconnected dust collection chamber 20b and a bag opening 20a, with the bag opening 20a used to allow airflow to enter the dust collection chamber 20b.

[0043] For example, please refer to Figure 8 and Figure 9 The filter structure 20 has a seam 21. The three-dimensional random fiber filter can be cut into a suitable shape and then connected to form a seam 21 at the connection point. This facilitates processing and helps reduce production costs.

[0044] In some embodiments, the seam 21 is located on the side of the filter structure facing the dust collection chamber 20b. Since the seam 21 faces the dust collection chamber 20b, it helps to improve the aesthetic appearance of the filter structure.

[0045] The method of forming the seam 21 is not limited; for example, it can be sewing, fusion bonding, adhesive bonding, etc., and there is no restriction here.

[0046] In some embodiments, the filter structure 20 is formed by enclosing the same three-dimensional random fiber filter, the bag opening 20a extends along a first direction, and the length of the bag opening 20a along the first direction is greater than the width in the second direction. There are two seams 21, which are perpendicular to the first and second directions and are both perpendicular to the depth of the dust collection chamber 20b.

[0047] In this embodiment, the same three-dimensional random fiber filter is cut and two seams 21 are formed at the splicing point, thereby enclosing the dust collection chamber 20b and the bag opening 20a. This helps to reduce the number of seams 21 and reduce the number of processing steps.

[0048] In some embodiments, please refer to Figure 8 and Figure 9 The two seams 21 are located on opposite sides of the dust collection chamber 20b in the first direction, or one seam 21 is located on one side of the dust collection chamber 20b in the first direction, and the other seam 21 is located on the side of the dust collection chamber 20b away from the bag opening 20a. This helps to maintain the integrity of a large area of ​​the sidewalls on opposite sides of the filter structure 20 in the second direction, which helps to improve the aesthetic appearance.

[0049] In some embodiments, the cross-sectional area of ​​the dust collection chamber 20b decreases sequentially from the bag opening 20a toward the bottom wall near the dust collection chamber 20b; and / or, the cross-sectional profile of the dust collection chamber 20b is approximately rectangular, wherein the cross-section is perpendicular to the direction from the bag opening 20a toward the bottom wall near the dust collection chamber 20b.

[0050] In embodiments where the cross-sectional area of ​​the dust collection chamber 20b decreases sequentially, the bag opening 20a is larger, which facilitates fitting the filter structure 20 onto the outer periphery of other structures (the first support frame described below). Furthermore, the larger bag opening 20a facilitates the airflow entering the dust collection chamber 20b at a larger flow rate.

[0051] In embodiments where the cross-sectional profile of the dust collection chamber 20b is rectangular, the filter structure 20 can be fitted onto the periphery of other structures with a generally rectangular cross-section. Of course, in other embodiments, the cross-sectional profile of the dust collection chamber 20b can also be other shapes, such as circular.

[0052] It should be noted that since the filter structure 20 is composed of a flexible three-dimensional random fiber filter, the filter structure 20 itself is relatively soft and may not be able to maintain the designed shape. Therefore, the cross-sectional profile here refers to the cross-sectional profile of the filter structure 20 when it is unfolded and stretched to the designed state.

[0053] In some embodiments, please refer to Figure 10 The three-dimensional random fiber filter includes a first trapezoidal region 2011 and a second trapezoidal region 2012. It should be noted that this refers to the shape of the three-dimensional random fiber filter when it has been cut and not yet enclosed. Figure 10 In the three-dimensional random fiber filter, the first trapezoidal region 2011 and the second trapezoidal region 2012 are located on both sides of the dashed line L. The first trapezoidal region 2011 and the second trapezoidal region 2012 are arranged symmetrically. The short base of the trapezoid of the first trapezoidal region 2011 and the short base of the trapezoid of the second trapezoidal region 2012 are directly or indirectly connected. The long base of the trapezoid of the first trapezoidal region 2011 20111 and the long base of the trapezoid of the second trapezoidal region 2012 20121 enclose the bag opening 20a. The trapezoidal waist 20112 of the first trapezoidal region 2011 and the trapezoidal waist 20122 of the second trapezoidal region 2012 are connected to form a seam, and the trapezoidal waist 20113 of the first trapezoidal region 2011 and the trapezoidal waist 20123 of the second trapezoidal region 2012 are connected to form another seam. Thus, when the three-dimensional random fiber filter mesh surrounds and forms the dust collection chamber 20b and the bag opening 20a, only the side walls on both sides have seams 21, and there are no seams 21 in other positions. In addition, due to the construction of the first trapezoidal region 2011 and the second trapezoidal region 2012, the cross-sectional area of ​​the dust collection chamber 20b decreases sequentially from the bag opening 20a toward the bottom wall of the dust collection chamber 20b, and the cross-sectional outline of the dust collection chamber 20b is roughly rectangular.

[0054] In some embodiments, the garment processing device includes a woven filter unit, which and the filter structure 20 are arranged along the airflow direction, i.e., the woven filter unit is located upstream and / or downstream of the filter structure 20 in the airflow direction. Thus, the woven filter unit and the filter structure 20 constitute a multi-stage filtration system, which helps to further improve the filtration effect.

[0055] It should be noted that the woven filter is a two-dimensional planar woven mesh. The pore shape of the woven filter unit is regular, the pore size is relatively uniform, the structural strength is high, and it is resistant to erosion and repeated cleaning.

[0056] In some embodiments, the woven filter unit includes a first woven filter located upstream of the filter structure 20 in the airflow direction; and / or, the woven filter unit includes a second woven filter located downstream of the filter structure 20 in the airflow direction.

[0057] In an embodiment with a first woven filter, the airflow first passes through the first woven filter unit. The airflow first passes through the first woven filter located upstream of the filter structure 20. Large particles of impurities are intercepted by the first woven filter unit, which plays a coarse filtration role. The airflow after coarse filtration flows through the filter structure 20. The filter structure 20 uses its three-dimensional random fiber filter to filter the airflow again, which is beneficial for intercepting small particles of impurities, thereby further improving the filtration effect and taking into account both filtration efficiency and filtration effect.

[0058] In an embodiment with a second woven filter, the airflow first flows through the filter structure 20 and then through the second woven filter, thus improving the filtration effect through two filtrations.

[0059] In an embodiment having a first woven filter and a second woven filter, the filter structure 20 is located between the first woven filter and the second woven filter, and the airflow undergoes at least three stages of filtration.

[0060] In some embodiments, please refer to Figure 5 The garment processing equipment includes a support frame unit 30, and a filter structure 20 is disposed on the support frame unit 30. In this embodiment, the support frame unit 30 provides support for the filter structure 20, which helps to stably maintain the filter structure 20 in the air duct and resist the impact of airflow. Of course, in other embodiments, the support frame unit 30 may not be provided, and the structure of the air duct itself may be used to fix the filter structure 20.

[0061] In some embodiments, the filter structure 20 is detachably disposed from the support frame unit 30 as a consumable. This facilitates quick disassembly and installation of the filter structure 20 and the support frame unit 30, and allows for rapid replacement of the filter structure 20. After a period of use, the filter structure 20 can be removed from the support frame unit 30 and replaced with a new filter structure 20. It is understood that the manufacturing cost of the filter structure 20 is lower than that of a woven filter screen, and using the filter structure 20 as a consumable will not significantly increase the user's operating costs.

[0062] In some embodiments, the filter structure 20 and the support frame unit 30 form a manual disassembly and assembly structure, meaning that users can disassemble it by hand without the need for tools. This facilitates manual disassembly and assembly of the filter structure 20, improving its ease of use.

[0063] In some specific embodiments, the filter structure 20 and the support frame unit 30 are detachably connected by at least one of Velcro or magnetic coupling structures. Specifically, these assembly structures are manual disassembly and assembly structures. This allows users to easily disassemble and install the filter structure 20 by hand (without the aid of tools, directly by hand).

[0064] Specifically, the Velcro includes a first adhesive piece and a second adhesive piece. One of the first and second adhesive pieces has a hook side, and the other has a rough side. The first adhesive piece is fixed to the filter structure 20, and the second adhesive piece is fixed to the support frame unit 30. The connection is achieved by the interlocking of the hook and rough sides of the first and second adhesive pieces. To disassemble, simply pull the first adhesive piece to separate it from the second adhesive piece. After replacing the filter structure 20, simply reattach the first adhesive piece of the new filter structure 20 to the second adhesive piece.

[0065] The magnetic attraction structure includes a first magnetic attraction structure and a second magnetic attraction structure. The first magnetic attraction structure is fixed to the filter structure 20, and the second magnetic attraction structure is fixed to the support frame unit 30. At least one of the first and second magnetic attraction structures is a permanent magnet, and the other is a permanent magnet or a ferromagnetic material. In this way, the magnetic attraction force of the two structures constrains the filter structure 20 to the support frame unit 30.

[0066] In some embodiments, the woven filter unit is fixed to the support frame unit 30, meaning that the support frame unit 30 can simultaneously support the installation of both the woven filter unit and the filter structure 20. Of course, in other embodiments, the woven filter unit may not be mounted on the support frame unit 30.

[0067] In some specific embodiments, the woven filter unit and the support frame unit 30 form a non-removable assembly structure or a tool-removable assembly structure. Since the woven filter unit does not need to be replaced, using a reliable, non-removable, or inconveniently removable method to fix the woven filter unit ensures the reliability of the connection between the woven filter unit and the support frame unit 30 and prevents users from arbitrarily disassembling it. A non-removable assembly structure refers to a structure that requires structural damage to disassemble, cannot be restored, and cannot be repeatedly disassembled and reassembled; examples include welding, bonding, riveting, and integral molding. A tool-removable assembly structure refers to a structure that is not easily disassembled and requires tools for disassembly; examples include screw connections and bolt connections.

[0068] It should be noted that the support frame unit 30 and the filtering structure disposed on the support frame unit 30 constitute the airflow filtering assembly 200.

[0069] The following is a brief description of the airflow filtration assembly 200 in four specific embodiments.

[0070] First specific embodiment Please see Figure 5The support frame unit 30 includes a first support frame 30A, which has a first filter chamber 301 and a first air inlet 302 that are interconnected. The filter structure 20 is sleeved on the outer periphery of the first support frame 30A or disposed inside the first filter chamber 301. Airflow enters the first filter chamber 301 from the first air inlet 302 and flows through the filter structure 20 to achieve filtration.

[0071] In the embodiment where the filter structure 20 is fitted around the outer periphery of the first support frame 30A, during installation, the first support frame 30A is inserted into the dust collection chamber 20b through the bag opening 20a, thus supporting the filter structure 20. Airflow enters the first filter chamber 301 from the first air inlet 302 of the first support frame 30A, flows outward from the first filter chamber 301, and passes through the filter structure 20, whereby the filter structure 20 filters the airflow. It should be noted that the first air inlet 302 of the first support frame 30A is positioned in the opposite direction of insertion; thus, after the first support frame 30A is inserted into the filter structure 20, the first air inlet 302 of the first support frame 30A will not be blocked by the filter structure 20. In this embodiment, the airflow filtering assembly 200 has a filter structure 20 that can be fitted around the outer periphery of the first support frame 30A. The first support frame 30A provides support for the filter structure 20, which can effectively support the filter structure 20 and maintain its shape. This helps to keep the filter structure 20 stably in the air duct and resist the impact of airflow. In addition, fitting the filter structure 20 around the outer periphery of the first support frame 30A increases the contact area between the two, which helps to increase the installation stability of the filter structure 20 and makes it less likely to fall off the first support frame 30A.

[0072] In the embodiment where the filter structure 20 is disposed inside the first filter chamber 301, the filter structure 20 is simply installed into the first filter chamber 301, and after installation, the bag opening 20a faces the first air inlet 302.

[0073] It should be noted that the filter structure 20 needs to cover all the air outlet positions of the first support frame 30A so that the airflow exiting the first support frame 30A can all flow through the filter structure 20 to achieve filtration.

[0074] For example, the filter structure 20 is detachably disposed on the first support frame 30A. The filter structure 20 can be removed from the first support frame, making it convenient for the user to replace the filter structure 20. In this way, the filter structure 20 can be used as a consumable. Of course, the filter structure 20 can also be removed, cleaned, and reused. It is understood that the manufacturing cost of the filter structure 20 is lower than that of a woven filter screen, and using the filter structure 20 as a consumable will not significantly increase the user's operating costs.

[0075] In some embodiments, where the filter structure 20 is fitted onto the outer periphery of the first support frame 30A, the first support frame 30A abuts against the filter structure 20 in a direction away from the first filter cavity 301, causing the filter structure 20 to be positioned on the outer periphery of the first support frame based on the frictional force generated by the abutment. That is, the circumferential dimension of the filter structure 20 is slightly smaller than the dimension of the first support frame 30A. During installation, after the first support frame 30A is inserted into the filter structure 20, the filter structure 20 is tensioned and tightly pressed against the outer periphery of the first support frame 30A, resulting in greater friction. This fixes the filter structure 20 relative to the first support frame 30A, thus achieving fixation of the filter structure 20 without the need for other additional connection measures. The structure is simple and allows users to easily disassemble and install the filter structure 20 by hand, improving ease of installation and disassembly.

[0076] In other embodiments, the filter structure 20 and the first support frame 30A are detachably connected by at least one of Velcro, magnetic coupling, or hook structure. This allows users to easily disassemble and install the filter structure 20 by hand, improving ease of assembly and disassembly.

[0077] Specifically, the Velcro includes a first adhesive piece and a second adhesive piece. One of the first and second adhesive pieces has a hook side, and the other has a rough side. The first adhesive piece is fixed to the filter structure 20, and the second adhesive piece is fixed to the first support frame 30A. The connection is achieved by the interlocking of the hook and rough sides of the first and second adhesive pieces. To disassemble, simply pull the first adhesive piece to separate it from the second adhesive piece. After replacing the filter structure 20, simply reattach the first adhesive piece of the new filter structure 20 to the second adhesive piece.

[0078] The magnetic attraction structure includes a first magnetic attraction structure and a second magnetic attraction structure. The first magnetic attraction structure is fixed to the filter structure 20, and the second magnetic attraction structure is fixed to the first support frame 30A. At least one of the first and second magnetic attraction structures is a permanent magnet, and the other is a permanent magnet or a ferromagnetic material. In this way, the magnetic attraction force of the two structures constrains the filter structure 20 to the first support frame 30A.

[0079] In some embodiments, the first woven filter of the airflow filtering assembly 200 is disposed on the first support frame 30A, and the filtering structure 20 is located downstream of the first woven filter along the airflow direction. It should be noted that the filtration accuracy of the first woven filter is less than that of the filtering structure 20.

[0080] In this embodiment, the first woven filter and the filter structure 20 constitute a two-stage filtration system, which helps to improve the filtration effect. The first woven filter is beneficial for filtering large particles or larger lint, while the filter structure 20 filters fine fluff.

[0081] In some embodiments, please refer to Figure 5 The first support frame 30A includes a first frame portion 31 and a second frame portion 32. One end of the first frame portion 31 and one end of the second frame portion 32 are rotatably connected. The first frame portion 31 and the second frame portion 32 can rotate relative to each other so that the first support frame 30A can be opened or closed. Figure 5 The first support frame 30A is in a closed state. When installing the filter structure 20, the first support frame 30A needs to be closed first, and then the filter structure 20 is fitted. In this embodiment, when the first frame portion 31 and the second frame portion 32 are opened, it is convenient to clean the internal space of the first support frame 30A.

[0082] In a first specific embodiment, the support frame unit 30 may have only a first support frame 30A and no second support frame 30B, or it may have both a first support frame 30A and a second support frame 30B. Similarly, it may have only a filter structure 20 and no woven filter unit, or it may have both a filter structure 20 and a woven filter unit.

[0083] Second specific embodiment The structure of filter structure 20 is the same as that of the first specific embodiment.

[0084] Please see Figure 5 The support frame unit 30 includes a first support frame 30A and a second support frame 30B. The first support frame 30A and the second support frame 30B are arranged along the airflow direction, and the filter structure 20 is located between the first support frame 30A and the second support frame 30B.

[0085] It should be noted that the first support frame 30A can be located upstream of the second support frame 30B. In this case, the filter structure 20 can be installed on either the first support frame 30A or the second support frame 30B. Alternatively, the second support frame 30B can be located upstream of the first support frame 30A. In this case, the filter structure 20 can be installed on either the first support frame 30A or the second support frame 30B. Since the filter structure 20 is located between the first support frame 30A and the second support frame 30B, the filter structure 20 is constrained by both the first support frame 30A and the second support frame 30B, thus avoiding the risk of the filter structure 20 becoming trapped in the air duct due to detachment from the support frame unit 30.

[0086] In some embodiments, please refer to Figure 4 The second support frame 30B has a second air inlet 303 and a second filter chamber 304 that are interconnected, and the first support frame 30B is disposed in the second filter chamber 304.

[0087] In some embodiments, please refer to 5 to Figure 7The second support frame 30B includes a third frame portion 33 and a fourth frame portion 34. One end of the third frame portion 33 and one end of the fourth frame portion 34 are rotatably connected, allowing the third frame portion 33 and the fourth frame portion 34 to rotate relative to each other, thereby opening or closing the second support frame 30B. Thus, when it is necessary to insert the filter structure 20 and / or the first support frame 30A into the second support frame 30B, the third frame portion 33 and the fourth frame portion 34 are opened to facilitate the insertion of the filter structure 20 into the second filter chamber 304, and then the third frame portion 33 and the fourth frame portion 34 are closed. After filtering for a period of time, the third frame portion 33 and the fourth frame portion 34 are opened to remove the filter structure 20 for cleaning impurities or replacement of the filter structure 20. Of course, in the embodiment where the airflow filtering assembly 200 includes the first support frame 30A, when the first frame portion 31 and the second frame portion 32 are in the open state, the first support frame 30A and the filter structure 20 are installed as a whole into the second support frame 30B, or the first support frame 30A and the filter structure 20 are separated from the second support frame 30B as a whole under the action of external force.

[0088] In the second specific embodiment, there may be only a filter structure 20 without a woven filter unit, or there may be both a filter structure 20 and a woven filter unit.

[0089] Third specific embodiment The support frame unit 30 includes a first support frame 30A and a second support frame 30B, which are arranged along the airflow direction. The first support frame 30A may be located upstream of the second support frame 30B, or the second support frame 30B may be located upstream of the first support frame 30A.

[0090] The airflow filtration assembly 200 is simultaneously configured with a filter structure 20 and a woven filter unit. Both the filter structure 20 and the woven filter unit are disposed on a first support frame 30A; alternatively, both the woven filter unit and the filter structure 20 are disposed on a second support frame 30B; or, the woven filter unit is disposed on the first support frame 30A and the filter structure 20 is disposed on the second support frame 30B. It should be noted that in this embodiment, the first support frame 30A can be either the first support frame in the first / second specific embodiment or the second support frame in the first / second specific embodiment. That is, the filter structure 20 and the woven filter unit can be disposed on the same support frame or on different support frames.

[0091] In an embodiment where the woven filter unit is disposed on the first support frame 30A and the filter structure 20 is disposed on the second support frame 30B, the first support frame 30A is located upstream of the second support frame 30B along the airflow direction; and / or, the second support frame 30B has a second filter cavity 304, and the first support frame 30A is accommodated in the second filter cavity 304 to form a nested structure.

[0092] In this way, the airflow will first pass through the woven filter unit. The airflow passes through the woven filter unit located upstream of the filter structure 20. Large particles of impurities are intercepted by the woven filter unit, which plays a coarse filtration role. After coarse filtration, the airflow flows through the filter structure 20. The filter structure 20 uses its three-dimensional random fiber filter to filter the airflow again, which is conducive to intercepting small particles of impurities, thereby further improving the filtration effect and taking into account both filtration efficiency and filtration effect.

[0093] Fourth embodiment The support frame unit 30 includes a first support frame 30A and a second support frame 30B, which are arranged along the airflow direction. The first support frame 30A may be located upstream of the second support frame 30B, or the second support frame 30B may be located upstream of the first support frame 30A.

[0094] The airflow filtration assembly 200 includes a filter structure 20 and a woven filter unit. The woven filter unit includes a first woven filter and a second woven filter. Both the first woven filter and the filter structure 20 are disposed on a first support frame, and the second woven filter is disposed on a second support frame. That is to say, when the airflow flows through the airflow filtration assembly 200, it undergoes at least three stages of filtration.

[0095] It should be noted that the first woven filter screen can be located upstream of the filter structure 20 or downstream of the filter structure 20.

[0096] In some embodiments, the mesh count of the first woven filter and the mesh count of the second woven filter are different, wherein the mesh count of the upstream filter is greater than that of the downstream filter, so as to achieve coarse filtration of the airflow first and then fine filtration of the airflow.

[0097] In some embodiments, the filter structure 20 is located between the first woven filter and the second woven filter.

[0098] It should be noted that in embodiments with a first woven filter and / or a second woven filter, when it is not necessary to filter fine lint, the filter structure 20 can be removed. In other words, the user can choose not to install the filter structure 20 and rely on the filtration capacity of the first woven filter and / or the second woven filter. That is, the filter structure 20 can be an optional accessory, and the user can decide whether to install it or not, thereby improving the convenience and selectivity of use.

[0099] In some embodiments, please refer to Figure 1 and Figure 2 The garment processing equipment has an installation port 10a, which communicates with an air duct. The filter structure 20 can be removed from or inserted into the air duct through the installation port 10a. This facilitates the user in removing the filter structure 20 for replacement, maintenance, cleaning, etc. It should be noted that in embodiments where the garment processing equipment includes a support frame unit 30, the support frame unit 30 may remain within the air duct, and only the filter structure 20 may be detached from the support frame unit 30 before being removed through the installation port 10a. In this embodiment, the support frame unit 30 may be fixed within the air duct, meaning it cannot be removed from the installation port 10a under any circumstances. Alternatively, the support frame unit 30 may be removable from the installation port 10a. In this case, the user can choose, for example, to remove only the filter structure 20 without removing the support frame unit 30, or the user can choose to remove both the support frame unit 30 and the filter structure 20 together.

[0100] In some embodiments, please refer to Figure 3 The garment handling device includes a front support 40, which has an interconnected pick-and-place port 40a and a mounting groove. The pick-and-place port 40a is connected to the garment handling chamber. Specifically, the front support 40 has a surrounding structure that extends approximately along the air inlet 302 at the front end of the cylindrical assembly to form the pick-and-place port 40a. The pick-and-place port 40a is aligned with the garment handling chamber, and the user places garments into the garment handling chamber through the pick-and-place port 40a.

[0101] In some embodiments, the mounting port 10a is formed on the sidewall of the front support 40 facing the loading / unloading port 40a, and the support frame unit 30 is disposed in the mounting groove and covers the mounting port 10a. The air inlet 302 of the support frame unit 30 is exposed in the mounting port 10a, so that airflow can flow into the support frame unit 30 from the air inlet 302.

[0102] In some embodiments, please refer to Figure 1 The mounting port 10a is formed on the front panel 11, and the support frame unit 30 can enter and exit the mounting port 10a in the front-rear direction of the garment handling equipment. For example, the mounting port 10a is located in the lower left region of the front panel 11.

[0103] In some embodiments, please refer to Figure 2 The mounting port 10a is formed on the top cover 12, and the support frame unit 30 can enter and exit the mounting port 10a along the height direction of the garment processing equipment.

[0104] It should be noted that the number of filter structures 20 can be one or more. The garment processing equipment can install filter structures 20 at different locations in the air duct.
