[0002] Existing garment drying equipment typically includes a centrifugal fan, a condenser, and a filter. During operation, the centrifugal fan drives air to circulate between the outer drum and the circulating air duct to dry the clothes inside. The filter removes and collects lint and impurities from the circulating air, preventing them from flowing into the outer drum and contaminating the clothes. However, after a period of use, lint and impurities accumulate in the filter, affecting ventilation and thus the drying function. Therefore, the filter needs to be removed for cleaning. Removing the filter is complex and requires frequent cleaning, impacting the user experience. Utility Model Content

[0028] 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.

[0029] 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 element 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.

[0030] 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.

[0031] The present invention addresses the problem mentioned in the background section that the centrifugal fan 30 of the existing clothing processing equipment cannot clean the filter structure 20 by means of airflow, resulting in a poor user experience. This invention provides a clothing processing equipment that enables the fan 30 to blow air in the opposite direction, thereby cleaning the filter structure 20 by means of airflow from the fan 30, which greatly improves the user experience.

[0032] According to one aspect of the present invention, a garment processing device is provided, comprising an outer cylinder 10, a circulating air duct, a filter structure 20, a fan 30, and a bypass structure. The two ends of the circulating air duct are connected to the outer cylinder 10. The filter structure 20 is disposed within the circulating air duct and is used to filter impurities in the gas supplied from the outer cylinder 10 to the circulating air duct. The fan 30 is disposed within the circulating air duct and is used to drive the outer cylinder 10 and the gas within the circulating air duct to circulate. The bypass structure is connected to the circulating air duct and is disposed at both ends of the fan 30. The bypass structure is used to redirect the gas within the circulating air duct to reverse the flow of air through the filter structure 20, thereby removing impurities from the filter structure 20.

[0033] With this configuration, bypass structures are located at both ends of the fan 30. When the fan 30 starts working, the bypass structures redirect the gas in the circulating air duct, causing the gas to blow against the filter structure 20, dislodging the lint adhering to the filter structure 20. This prevents the lint from clogging the filter structure 20, thus avoiding blockage and ensuring the normal drying operation of the garment processing equipment. This invention achieves automatic cleaning of the filter structure 20, eliminating the need for users to remove it for cleaning and significantly improving the user experience.

[0034] It is understood that, in a specific embodiment of this utility model, those skilled in the art can control the opening of the bypass structure in different ways. For example, the bypass structure can be set to automatically open after the clothing processing equipment has dried n times, controlling the gas in the circulating air duct to blow back against the filter structure 20 to peel off the lint attached to the filter structure 20. Alternatively, the bypass structure can be set to be opened manually by the user, so that the gas in the circulating air duct cleans the filter structure 20, etc. Such limitations on the opening method of the bypass structure 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.

[0035] Preferably, in a specific embodiment of this utility model, the control logic is designed to automatically clean the filter structure 20. After the clothing processing equipment has completed 10 drying cycles, the clothing processing equipment automatically starts the cleaning mode of the filter structure 20, opens the bypass structure, and starts the fan to the maximum wind speed and runs continuously for 3 minutes before stopping.

[0036] The specific structure of the bypass structure will be described below with reference to two embodiments:

[0037] like Figure 1 As shown, in Embodiment 1 of this utility model, the bypass structure includes a first bypass ventilation duct 41, a second bypass ventilation duct 42, a first valve 43, and a second valve 44. The two ends of the first bypass ventilation duct 41 are respectively connected to the circulating air duct, with connection points A and B respectively. The two ends of the second bypass ventilation duct 42 are respectively connected to the circulating air duct, with connection points C and D respectively. The position of the fan 30 is E. The connection points along the positive direction of the air flow in the circulating air duct are A, C, E, B, and D in sequence. The first valve 43 is located between connection points A and C, and the second valve 44 is located between connection points B and D.

[0038] With this setup, when the garment processing equipment is in normal drying mode, both the first valve 43 and the second valve 44 are open, and the gas in the circulating air duct flows sequentially through five connection points A, C, E, B, and D. When the garment processing equipment is cleaning the filter structure 20, both the first valve 43 and the second valve 44 are closed, and the gas flows from connection point E to connection point B, then through the first side ventilation duct 41, and flows into the circulating air duct through point A, blowing on the filter structure 20 to remove lint. The gas then enters the outer cylinder 10 through the circulating air duct, passes through the outer cylinder 10 to the other end of the circulating air duct, and finally enters the second side ventilation duct 42 through connection point D, enters the circulating air duct through point C, and returns to connection point E, thus forming a new cycle. By allowing the gas to blow against the filter structure 20 in reverse, the lint attached to the filter structure 20 is effectively removed, achieving automatic cleaning of the filter structure 20 and greatly improving the user experience.

[0039] like Figure 2As shown, in Embodiment 2 of this utility model, the bypass structure includes a third bypass ventilation duct 51, a fourth bypass ventilation duct 52, a third valve 53, a fourth valve 54, and a fifth valve 55. The two ends of the third bypass ventilation duct 51 are respectively connected to the circulating air duct, with connection points J and K respectively. One end of the fourth bypass ventilation duct 52 is connected to the circulating air duct, with connection point M. The other end of the fourth bypass ventilation duct 52 is connected to the outer cylinder 10. The position point of the fan 30 is E. The circulating air duct flows in the forward direction, with connection points J, M, E, and K in sequence. The third valve 53 is located between connection points J and M. The fourth valve 54 is located on the side away from the fan 30 at connection point K. The fifth valve 55 is located in the fourth bypass ventilation duct 52.

[0040] With this setup, when the garment processing equipment is in normal drying mode, both the third valve 53 and the fourth valve 54 are open, and the fifth valve 55 is closed. Gas flows forward along the circulating air duct, passing through connection points J, M, E, and K in sequence. When the garment processing equipment cleans the filter structure 20, the third valve 53 and the fourth valve 54 are closed, and the fifth valve 55 is open. Gas flows from connection point E to connection point K, then through the third bypass ventilation duct 51, enters the circulating air duct from connection point J, blows through the filter structure 20, and enters the outer cylinder 10. The gas in the outer cylinder 10 passes through the fourth bypass ventilation duct 52, enters the circulating air duct through connection point M, and then flows to connection point E, forming a new cycle. During normal drying, the fifth valve 55 is closed to avoid affecting the normal operation of the garment processing equipment.

[0041] like Figure 1 and Figure 2 As shown, the garment processing equipment also includes a heating device 60, which is located in the circulating air duct and between the filter structure 20 and the outer cylinder 10. The heating device 60 is used to heat the gas flowing through it.

[0042] With this configuration, the heating device 60 is used to heat the gas in the circulating air duct, so that the heated gas enters the outer cylinder 10 to dry the clothes inside the outer cylinder 10.

[0043] like Figures 1 to 2 As shown, the garment processing equipment also includes a condenser 70, which is located in the circulating air duct and between the fan 30 and the outer cylinder 10.

[0044] With this setup, the hot and humid gas inside the outer cylinder 10 enters the condenser 70 from bottom to top. Water in the condenser 70 sprays the hot and humid gas from top to bottom, causing the water vapor in the gas to condense, thus achieving dehumidification of the hot and humid air. During the reverse-blowing process of the filter structure 20 in the clothing processing equipment, the shed lint falls into the condenser 70. Water in the condenser 70 washes away the lint, and the wastewater generated by the condenser 70 flows along the condenser pipe to the bottom of the outer cylinder 10 and is discharged.

[0045] Furthermore, it is conceivable that the garment processing equipment also includes a water supply device connected to the condenser 70 to supply condensate to the condenser 70.

[0046] With this setup, when the condenser 70 is turned on, the water supply equipment also turns on to supply water to the condenser 70; when the condenser 70 is turned off, the water supply equipment also stops working.

[0047] It is conceivable that, in a specific embodiment of this utility model, the water supply device has a solenoid valve, which has a first gear and a second gear. The water flow in the first gear is greater than that in the second gear. When the clothing processing device is in normal drying process, the solenoid valve uses the second gear to supply water to the condenser 70. When the clothing processing device blows the filter structure 20 in reverse, the solenoid valve uses the first gear to rinse off the lint.

[0048] like Figure 1 and Figure 2 As shown, the garment processing equipment also includes a drain pump 81 and a drain pipe 82. The drain pump 81 is disposed on the drain pipe 82 and is used to pump water from the outer cylinder 10 to the drain pipe 82.

[0049] With this setup, the drain pipe 82 is located at the bottom of the garment processing equipment and is connected to the bottom of the outer drum 10. When the outer drum 10 needs to drain, the drain pump 81 draws water from the outer drum 10 and discharges it through the drain pipe 82.

[0050] Furthermore, it can be conceivable that the filter structure 20 is a raised structure, with one raised end of the filter structure 20 facing away from the fan 30.

[0051] With this design, the convex structure of filter 20 has a larger surface area at one end, increasing the contact area between the filter 20 and the gas. Lint in the gas adheres to the lower surface of filter 20 after filtration. The larger surface area and convex shape slow down lint accumulation, allowing for sufficient airflow channels and preventing the filter 20 from clogging due to excessive lint filtration, which could affect the normal operation of the garment processing equipment. Furthermore, the larger surface area of ​​the convex structure allows for maximum removal of lint from the filter 20 during reverse blowing, minimizing lint residue.

[0052] It is conceivable that in practical applications, the protrusion structure can adopt different shapes. For example, it can adopt a conical protrusion structure, or a hemispherical protrusion structure, or an ellipsoidal protrusion structure. Such changes to the shape of the protrusion structure do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0053] Preferably, a conical protrusion structure is more conducive to the use of the filter structure 20. The conical structure has an air-breaking effect. Since the wind speed and air volume are relatively high at this point, compared with the spherical structure, the conical structure of this application has an air-breaking effect, and the impact on the air volume can be minimized.

[0054] It is conceivable that, in practical applications, there are multiple options for the installation position of the filter structure 20 in the circulating air duct. For example, the filter structure 20 can be set between the bypass structure and the condenser 70, or the filter structure 20 can be installed inside the condenser 70, etc. Such adjustments and changes to the installation position of the filter structure 20 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0055] Preferably, in a specific embodiment of the present invention, the condenser 70 includes a condenser body and a condenser pipe, and the filter structure 20 is disposed in the condenser body.

[0056] With this setup, the filter structure 20 is placed inside the condenser body. During the reverse blowing of the filter structure 20 by the garment processing equipment, the air flow can peel off the lint from the surface of the filter structure 20. At the same time, the water entering the condenser 70 can rinse the filter structure 20, making the cleaning of the filter structure 20 more thorough and preventing the filter structure 20 from becoming clogged and causing the garment processing equipment to malfunction.

[0057] Furthermore, compared to conventional existing technologies that do not have a filter structure 20 at this location, the condensate flowing through the filter structure 20 in this application can also create a shower effect, causing the humid and hot air from the outer cylinder to be sprayed with the condensate in the condenser body once, and then sprayed with the condensate a second time in the condenser pipe, resulting in more thorough heat exchange and further increasing the dehumidification effect of the condensate on the humid and hot air.

[0058] Furthermore, the filter structure 20 is made of a flexible mesh material.

[0059] With this setup, the filter structure 20 is made of a flexible mesh material. The filter structure 20 can be bent and placed into the circulating air duct, and then unfolded and fixed at the installation position, avoiding the problem of the filter structure 20 having a large area and being difficult to install.

[0060] 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.
