[0007] In a preferred embodiment of the above-mentioned wire lint filtering device, the wire lint filtering device further includes a frame disposed at the edge of the filter screen.

[0024] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0025] It should be noted that in the description of this utility model, terms such as "upper," "lower," "inner," and "bottom," which indicate direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is merely for ease of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0026] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] Based on the fact that the lint filter devices in the prior art clothing processing equipment mentioned in the background are prone to generating noise during use, this utility model provides a lint filter device. The lint filter device is provided with a first air duct and a second air duct with gradually changing widths, which divides the air entering from the air inlet into two groups and enters the air outlet respectively, so as to guide the air, making the filter screen 20 less resistant to the air, avoiding noise generation, and greatly improving the user experience.

[0028] According to one aspect of the present invention, a lint filtering device is provided, comprising a filter box 10 and a filter screen 20. The filter box 10 has a front side wall 101, a rear side wall 103, a left side wall 102, and a right side wall 104. An air inlet is provided on the front side wall 101, and an air outlet is provided on the left side wall 102. The front side wall 101 and the left side wall 102 form an angle, and the left side wall 102 and the right side wall 104 are arranged in parallel. The filter screen 20 includes a first mesh surface 21 and a second mesh surface 22 connected to each other. Along the direction of air travel, the first mesh surface 21 is arranged to gradually approach the right side wall 104, so that the first air duct enclosed by the front side wall 101, the first mesh surface 21, and the right side wall 104 gradually narrows. Along the direction of air travel, the second mesh surface 22 is arranged to gradually move away from the right side wall 104, so that the second air duct enclosed by the rear side wall 103, the second mesh surface 22, and the right side wall 104 gradually widens.

[0029] With this configuration, part of the gas entering through the inlet passes through the first mesh surface 21 and enters the outlet, while the other part flows along the first air duct into the second air duct. The gas in the second air duct flows along the right side wall 104 and the rear side wall 103 before passing through the second mesh surface 22 and entering the outlet. Dividing the gas into two groups makes the gas flow smoother and less prone to turbulence. Furthermore, both the first mesh surface 21 and the second mesh surface 22 are angled to the gas flow direction, preventing direct impact of gas on the filter screen 20 and thus avoiding noise. This new wire lint filter device solves the problem of noise generation in existing wire lint filters.

[0030] It is conceivable that, in practical applications, those skilled in the art can set the included angle between the front sidewall 101 and the left sidewall 102 to an angle of less than 180°. For example, the included angle between the front sidewall 101 and the left sidewall 102 can be set to a right angle as shown in the figure, or the included angle between the front sidewall 101 and the left sidewall 102 can be set to 60°, etc. Such changes to the included angle between the front sidewall 101 and the left sidewall 102 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0031] Preferably, the included angle between the front sidewall 101 and the left sidewall 102 is set as a right angle, so that the lint filter device is box-shaped as a whole, which makes installation and processing more convenient.

[0032] In practical applications, those skilled in the art can fix the filter screen 20 in various ways. For example, the edge of the filter screen 20 can be fixed to the edge of the filter box 10, and the connection position of the first mesh surface 21 and the second mesh surface 22 can be fixed inside the filter box 10 to tension the filter screen 20, thereby forming the first air duct and the second air duct. Alternatively, a supporting frame can be installed around the filter screen 20 to fix the filter screen 20. Or, the first mesh surface 21 and the second mesh surface 22 can be integrally formed, etc. Such changes to the fixing method of the filter screen 20 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0033] Preferably, the first mesh surface 21 and the second mesh surface 22 are integrally formed into one mesh surface.

[0034] This design makes the processing of the first mesh surface 21 and the second mesh surface 22 more convenient and saves costs. Furthermore, the one-piece molding reduces the processing difficulty of the first mesh surface 21 and the second mesh surface 22, eliminating the need for connecting parts between them.

[0035] It is conceivable that, in a specific embodiment of this utility model, the filter screen 20 is provided with a frame at its edge, the length of which is greater than the distance between the front sidewall 101 and the rear sidewall 103. Those skilled in the art can bend the frame to install it into the filter box 10, so that the filter screen 20 is divided into a first mesh surface 21 and a second mesh surface 22 along the bending position.

[0036] It is conceivable that those skilled in the art could design the filter box to have an open top, allowing users to empty the lint filter through the open top of the filter box after removing the lint filter from the garment processing equipment, making it more convenient for users.

[0037] like Figure 1 As shown, a support structure for fixing the filter screen 20 is also provided between the filter screen 20 and the left side wall 102. One end of the support structure is connected to the left side wall 102 or the right side wall 104, and the other end of the support structure is connected to the connection position of the first mesh surface 21 and the second mesh surface 22.

[0038] With this setup, the support device fixes the installation position of the filter screen 20, preventing the filter screen 20 from becoming loose or displaced during use.

[0039] In practical applications, those skilled in the art can set different support devices to fix the filter screen 20. For example, one end of the support structure can be connected to the left side wall 102, and the other end of the support structure can support or tighten the filter screen 20 to tension the first mesh surface 21 and the second mesh surface 22. Alternatively, one end of the support structure can be connected to the right side wall 104, and the other end of the support structure can drag or support the filter screen 20 to tension the first mesh surface 21 and the second mesh surface 22, etc. Such changes to the position and usage of the support device do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0040] The specific structure of the support structure will be described below with reference to two embodiments:

[0041] like Figure 1 As shown, in Embodiment 1 of this utility model, the support structure includes a support plate 31. One end of the support plate 31 abuts against the left side wall 102, and the other end of the support plate 31 is connected to the connection position of the first mesh surface 21 and the second mesh surface 22. The support plate 31 is inclined relative to the vertical line of the left side wall 102 in the direction away from the air inlet. The included angle between the support plate 31 and the vertical line of the left side wall 102 is γ, 30°≤γ≤40°.

[0042] With this configuration, when the gas entering through the inlet passes through the first mesh surface 21, the support plate 31 can guide the gas flowing through it, making the gas flow smoother. Furthermore, the other side of the support plate 31 can guide the gas flowing through the second mesh surface 22. The gas will create turbulence as it passes through the narrow opening at the connection between the first and second air ducts. Gas near the right side wall 104 flows along the right side wall 104, while gas away from the right side wall 104 will form vortices. The other side of the support plate 31 can slow down these vortices, allowing the gas to flow smoothly before entering the outlet. The angle between the support plate 31 and the perpendicular to the left side wall 102 is between 30° and 40°, making the gas flow smoother and preventing the gas from directly impacting the support plate 31, thus reducing noise generated by the gas flow.

[0043] Preferably, the angle between the support plate 31 and the perpendicular line of the front sidewall 101 is 30°, so that the impact of gas on the support plate 31 is small and noise is not easily generated.

[0044] By adjusting the angle γ between the support plate 31 and the perpendicular line of the left side wall 102, the size of the air outlets corresponding to the first mesh surface 21 and the second mesh surface 22 can be adjusted. Setting γ between 30° and 40° ensures that the air outlet corresponding to the first mesh surface 21 is larger than the air outlet corresponding to the second mesh surface 22. Most of the gas entering the inlet passes through the first mesh surface 21 along the first air duct and then enters the air outlet. A small portion of the gas flows along the first and second air ducts to the rear side wall 103, where it is guided through the rear side wall 103 and passes through the second mesh surface 22 before entering the air outlet. Compared to the prior art where most gas flows along the right side wall 104 to the rear side wall 103, impacts the rear side wall 103, and then changes direction to enter the air outlet, this solution only allows a small portion of the gas to flow to the rear side wall 103, with most gas entering the air outlet through the first mesh surface 21. This effectively diverts the gas flow and avoids a large amount of gas impacting the rear side wall 103, thus preventing noise.

[0045] Furthermore, it is conceivable that the lint filter device also includes a frame, which is set at the edge of the filter screen 20. The frame is used to support the filter screen 20. The frame has a groove, which is set at the connection position between the first mesh surface 21 and the second mesh surface 22. The groove is connected to the support plate 31.

[0046] With this configuration, the frame supports the filter screen 20, allowing the filter screen 20 to be tensioned to form a first mesh surface 21 and a second mesh surface 22. One end of the support plate 31 abuts against the left side wall 102, and the other end of the support plate 31 is connected to the groove to prevent the support plate 31 from slipping or falling off during the process of supporting the filter screen 20.

[0047] The frame is made of flame-retardant PET material to prevent damage to the frame or other structures of the garment processing equipment caused by high temperatures during use.

[0048] like Figure 3 As shown, in Embodiment 2 of this utility model, the support structure includes a fixing member 32. One end of the fixing member 32 is connected to the right side wall 104, and the other end of the fixing member 32 is connected to the connection position of the first mesh surface 21 and the second mesh surface 22.

[0049] With this configuration, the fastener 32 secures the filter screen 20, preventing it from loosening or shifting during use and affecting the normal operation of the garment processing equipment. The fastener 32 supports the filter screen 20, ensuring that the first mesh surface 21 and the second mesh surface 22 are taut.

[0050] In practical applications, those skilled in the art can set a frame at the edge of the filter screen, and both the frame and the fastener 32 are made of PET flame-retardant material.

[0051] In practical applications, those skilled in the art can use various methods to set the connection between the frame and the fastener 32. For example, the frame and the fastener 32 can be integrally formed, or the frame and the fastener 32 can be processed separately and then fixedly connected, etc. Such changes to the connection between the frame and the fastener do not deviate from the principle and protection scope of this utility model, and should all be included within the protection scope of this utility model.

[0052] It can be inferred that, along the air inlet direction of the filter box 10, the distance between the connection position of the first mesh surface 21 and the second mesh surface 22 and the front side wall 101 is a, and the distance between the connection position of the first mesh surface 21 and the second mesh surface 22 and the rear side wall 103 is b, where 2≥a / b≥3.

[0053] With this setting, the connection position of the first mesh surface 21 and the second mesh surface 22 is set at 2 / 3 to 3 / 4 of the distance from the air inlet direction in the filter box 10, so that the width change of the first air duct and the second air duct is relatively gradual and there will be no sudden change in width, thus avoiding gas turbulence.

[0054] Preferably, the connection position of the first mesh surface 21 and the second mesh surface 22 is set at 2 / 3 of the distance from the air inlet direction in the filter box 10, so that a / b equals 2 / 3, and the width change of the first air duct and the second air duct is more gradual, which is conducive to the stable flow of gas.

[0055] It can be inferred that, along the air outlet direction of the filter box 10, the distance between the connection position of the first mesh surface 21 and the second mesh surface 22 and the left side wall 102 is c, and the distance between the connection position of the first mesh surface 21 and the second mesh surface 22 and the right side wall 104 is d, where 2≥c / d≥3.

[0056] With this setting, the connection position of the first mesh surface 21 and the second mesh surface 22 is set at 2 / 3 to 3 / 4 of the distance from the air outlet along the filter box 10. This makes the angle of contact between the gas and the first mesh surface 21 and the second mesh surface 22 during the gas flow more gradual, without generating a large impact. This allows the gas to pass through the first mesh surface 21 and the second mesh surface 22 more smoothly without generating a large noise.

[0057] Furthermore, it is understood that the filter cartridge 10 also includes a guide structure for guiding the gas input into the air inlet.

[0058] With this configuration, the guide structure is placed inside the filter box 10 to guide the gas inside the filter box 10, making the gas flow inside the filter box 10 smoother and less noisy, effectively improving the user experience.

[0059] In one specific embodiment of this utility model, such as Figure 1 As shown, the guide structure includes a guide surface 40, which is disposed on the right side wall 104 and is an arc-shaped curved surface.

[0060] With this setup, when the gas in the second air duct flows to the right side wall 104, the gas flows along the guide surface 40 to generate circulation, and then smoothly passes through the second mesh surface 22. The guide surface 40 guides and buffers the gas in the second air duct, avoiding turbulence caused by unstable gas flow, which could generate noise and affect the user experience.

[0061] According to another aspect of the present invention, a garment processing device is provided, including an outer drum, a circulating air duct, and the aforementioned lint filter device. The two ends of the circulating air duct are respectively connected to the outer drum, and the lint filter device is disposed inside the circulating air duct.

[0062] With this setup, the clothing processing equipment equipped with the aforementioned lint filter can perform drying work better, and noise is less likely to be generated during the airflow through the lint filter, greatly improving the user experience.

[0063] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
