Description

Technical Field

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

[0002] In related technologies, clothing processing equipment such as dryers typically include functional modules such as atomizing devices for wrinkle removal. However, during use, lint and other dirt accumulate on these modules. Over time, this can cause these modules to malfunction, affecting reliability. Utility Model Content

[0003] This application provides a garment processing device to solve the problem that the functional modules of existing garment processing devices are prone to failure due to the accumulation of lint.

[0004] In a first aspect, embodiments of this application provide a garment processing device, comprising:

[0005] The equipment body has a drying air duct.

[0006] An air duct is installed on the equipment body. The air duct forms an auxiliary air channel. The air inlet end of the auxiliary air channel is connected to the outside, and the air outlet end of the auxiliary air channel is connected to the drying air channel.

[0007] The functional modules are located in the additional air duct;

[0008] The first fan is located at the air inlet end of the additional air duct.

[0009] In some embodiments of this application, a second fan is provided in the drying duct, and the second fan is connected to the first fan through a transmission component; the second fan is adapted to rotate under the action of airflow in the drying duct, and drives the first fan to rotate through the transmission component.

[0010] In some embodiments of this application, the first fan is provided with a first drive wheel, the second fan is provided with a second drive wheel, and the transmission component includes a transmission belt, one end of which is sleeved on the first drive wheel and the other end of which is sleeved on the second drive wheel.

[0011] In some embodiments of this application, a negative electrode plate is provided in the additional air duct, and the negative electrode plate is configured to adsorb lint in the additional air duct.

[0012] In some embodiments of this application, the additional air duct is provided with an opening that communicates with the outside air, and the opening is provided corresponding to the negative electrode plate.

[0013] In some embodiments of this application, the clothing processing device further includes a filter element disposed at the air inlet end of the additional air duct and located in front of the first fan.

[0014] In some embodiments of this application, an air guide is provided at the connection between the additional air duct and the drying air duct.

[0015] In some embodiments of this application, the number of functional modules is multiple, and the multiple functional modules are arranged sequentially at intervals along the air intake direction of the additional air duct.

[0016] In some embodiments of this application, the clothing processing equipment further includes a drying fan, which is disposed in the drying duct and is used to drive the airflow within the drying duct.

[0017] In some embodiments of this application, the functional module includes at least one of a fogging wrinkle removal module, a negative ion generator, and a fogging aromatherapy module.

[0018] The garment processing equipment provided in this application includes a main body, an air duct, a functional module, and a first fan. The main body forms a drying air duct; the air duct is disposed within the main body and forms an auxiliary air duct, with its inlet end connected to the outside and its outlet end connected to the drying air duct; the functional module is disposed within the auxiliary air duct; and the first fan is disposed at the inlet end of the auxiliary air duct. By placing the functional module within the auxiliary air duct, a certain degree of isolation is achieved between it and the drying air duct, reducing the possibility of lint accumulation. Simultaneously, during equipment operation, negative pressure is generated within the drying air duct due to airflow. This results in a relatively high air pressure within the auxiliary air duct. Based on this pressure difference, any small amount of lint and dust that may be generated within the auxiliary air duct will naturally flow towards and enter the lower-pressure drying air duct under the influence of air pressure, rather than depositing on the functional module within the auxiliary air duct. This effectively avoids the problem of blockage or performance degradation of the functional module due to dirt accumulation, significantly improving its reliability and service life. The first fan also helps to blow lint from the auxiliary air duct into the drying air duct.

[0019] Additional aspects and advantages of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0036] In related technologies, existing clothing processing equipment, such as dryers, uses ultrasonic atomizers for aromatherapy and wrinkle removal during the drying process, and negative ion generators to eliminate static electricity. During the use of these components, lint and other dirt accumulate on the ultrasonic atomizer's vibrating plates or the negative ion generator's electrodes. Over time, this can cause malfunctions in the ultrasonic generator and negative ion generator electrodes, affecting reliability. To address reliability issues, filters are typically installed in the air duct to remove airborne lint; however, to maintain functionality, these filters require regular cleaning, impacting the user experience.

[0037] This application provides a garment processing device to solve the problem that functional modules of existing garment processing devices are prone to failure due to the accumulation of lint and hair. The following will be described in conjunction with the accompanying drawings. Figure 1-3 Please provide an explanation.

[0038] The garment processing equipment provided in this application embodiment is referenced. Figure 1 As shown, the device includes a main body 100, an air duct 200, a functional module 300, and a first fan 220. The main body 100 forms a drying air duct 110. The air duct 200 is disposed on the main body 100 and forms an auxiliary air duct 210. The air inlet end of the auxiliary air duct 210 is connected to the outside, and the air outlet end of the auxiliary air duct 210 is connected to the drying air duct 110. The functional module 300 is disposed in the auxiliary air duct 210. The first fan 220 is disposed at the air inlet end of the auxiliary air duct 210.

[0039] For example, the device body 100 is provided with an air duct 200, which forms an independent auxiliary air duct 210. The auxiliary air duct 210 is connected to the outside air. Functional modules 300, such as atomizing wrinkle removal devices and fragrance release devices, are installed on the auxiliary air duct 210, so that these functional modules 300 are not directly exposed to the drying air duct 110 filled with lint and fibers. A first fan 220 is installed near the air inlet of the auxiliary air duct 210, and its function is to draw in outside air through the air inlet of the auxiliary air duct 210 and push the air to flow along the auxiliary air duct 210.

[0040] Optionally, when the garment processing equipment is running, the first fan 220 starts, drawing in air from the outside. The air flows through the auxiliary air duct 210, passing through the functional module 300 (such as an atomizing device that generates water mist) located therein. The air carrying the substances (such as water mist) generated by the functional module 300 then enters the drying air duct 110 from the outlet of the auxiliary air duct 210, merging with the main drying airflow. Finally, these substances (such as water mist) come into contact with the garments, providing wrinkle removal, humidification, or other care effects.

[0041] In this embodiment, since the functional module 300 is located in a separate auxiliary air duct 210, and this air duct mainly draws in relatively clean external air, rather than the main drying air duct 110 that carries out a large amount of lint, fibers and dirt from the roller, the risk of the functional module 300 (such as atomizing nozzles, heating elements, etc.) being contaminated, blocked or damaged is greatly reduced.

[0042] During equipment operation, the drying duct 110 generates negative pressure due to high-speed airflow, while the air pressure in the auxiliary duct 210 is relatively high. This pressure difference causes any small amount of impurities that may be generated in the auxiliary duct 210 (even if present) to tend to flow towards and enter the main drying duct 110, rather than depositing on the functional module 300, further reducing dirt accumulation on the functional module 300. Simultaneously, the first fan 220 supplies air to the drying duct 110 through the auxiliary duct 210, further reducing the possibility of lint and dust entering the auxiliary duct 210.

[0043] Furthermore, the substances released by the functional module 300 (such as water mist and fragrance) are more effectively and concentratedly transported to the drying air duct 110 after passing through the auxiliary air duct 210 and being pushed by the first fan 220, and are evenly applied to the clothes, ensuring that the wrinkle removal, softening, and fragrance functions can achieve better actual results and improve the overall care level of the clothes.

[0044] In one alternative implementation, refer to Figure 1 and Figure 2 As shown, a second fan 400 is installed in the drying duct 110. The second fan 400 is connected to the first fan 220 through a transmission component 410. The second fan 400 is adapted to rotate under the action of airflow in the drying duct 110 and drives the first fan 220 to rotate through the transmission component 410.

[0045] In this embodiment, an additional impeller or fan, namely a second fan 400, is provided inside the drying air duct 110 of the equipment body 100. The second fan 400 can be installed at a key position of air flow in the drying air duct 110 so that it can be rotated to the greatest extent affected by the main airflow.

[0046] The second fan 400 can be driven by the airflow within the drying duct 110. When the equipment is drying, as air flows at high speed through the main drying duct 110, the airflow impacts the blades of the second fan 400, causing it to rotate passively. The second fan 400 is connected to the first fan 220 via a transmission component 410 (e.g., a mechanical transmission device such as a belt, chain, gear, or shaft connection). When the second fan 400 is driven to rotate by the airflow in the drying duct 110, its rotational power is transmitted to the first fan 220 through the connected transmission component 410. Thus, the first fan 220 also rotates, drawing in air from the outside and driving the airflow in the auxiliary duct 210.

[0047] In this embodiment, there is no need to set up an additional dedicated power source to drive the first fan 220 to rotate, which reduces the overall energy consumption of the equipment and saves energy.

[0048] In one optional implementation, combined with Figure 1 and Figure 2 As shown, the first fan 220 is provided with a first drive wheel 221, the second fan 400 is provided with a second drive wheel 420, and the transmission component 410 includes a transmission belt, one end of which is sleeved on the first drive wheel 221 and the other end of which is sleeved on the second drive wheel 420.

[0049] Optionally, a first transmission wheel 221 is mounted on the shaft of the first fan 220, and a second transmission wheel 420 is mounted on the shaft of the second fan 400. The dimensions of the first transmission wheel 221 and the second transmission wheel 420 can be the same or different, depending on the designed transmission ratio. This embodiment does not impose any specific limitations on this.

[0050] When the airflow in the drying duct 110 passes the second fan 400, it impacts its blades, causing them to rotate. The rotation of the second fan 400 drives the second drive wheel 420 on its shaft to rotate as well. The rotation of the second drive wheel 420 transmits power to the first drive wheel 221 via a taut drive belt. The first drive wheel 221 then rotates, which in turn drives the main shaft and blades of the first fan 220 to rotate together, thereby achieving the function of drawing air in from the air inlet end of the auxiliary duct 210.

[0051] Belt drives offer relatively smooth operation and lower noise. Compared to direct shaft connections, they provide better cushioning and shock absorption, reducing impact on the bearings of the two fans and helping to extend equipment life. Furthermore, their simple structure and easy maintenance make them convenient. The transmission ratio can be easily adjusted by selecting first and second drive pulleys 221 and 420 of different diameters.

[0052] In one optional implementation, combined with Figure 1 and Figure 3 As shown, a negative electrode plate 230 is provided inside the auxiliary air duct 210, and the negative electrode plate 230 is configured to adsorb the hair inside the auxiliary air duct 210.

[0053] In this embodiment, the negative electrode plate 230 is an electrode plate made of conductive material, which generates a negative charge after being energized. When positively charged lint moves with the airflow within the auxiliary air duct 210, it will be strongly attracted by electrostatic attraction once it approaches the negatively charged negative electrode plate 230. This electrostatic force will cause the lint, which was originally moving in a straight line with the airflow, to deviate from its trajectory and be "pulled" towards the negative electrode plate 230. Ultimately, these lint particles will adhere to the negative electrode plate 230, thereby being separated from the airflow and preventing them from continuing to flow into the functional module 300 or entering the drying air duct 110. This greatly reduces the risk of the functional module 300 being contaminated, blocked, or damaged by wear from impurities, further improving the reliability and service life of the functional module 300.

[0054] In one optional implementation, combined with Figure 1 and Figure 3 As shown, the auxiliary air duct 210 is provided with an opening 240, which is connected to the outside air, and the opening 240 is provided corresponding to the negative electrode plate 230.

[0055] In this embodiment, one or more openings 240 are formed on the side wall of the auxiliary air duct 210. These openings 240 are located near the negative electrode plate 230, and their orientation is generally towards the indoor environment outside the device, allowing direct communication between the openings 240 and the indoor air. The negative electrode plate 230 is used to adsorb positively charged lint that moves with the airflow. When lint is adsorbed by the negative electrode plate 230 and its trajectory deviates, the presence of the opening 240 provides a direct discharge path for this adsorbed lint. After being deviated from the main airflow direction by electrostatic force, the lint will be directly discharged from the opening 240 and enter the indoor environment.

[0056] In an optional embodiment, the garment processing device further includes a filter (not shown) disposed at the air inlet of the auxiliary air duct 210 and located in front of the first fan 220.

[0057] In this embodiment, the filter element acts as a primary filter before air enters the auxiliary air duct 210. It captures some larger dust, lint, or other impurities, preventing these larger particles from directly entering the air duct and contaminating clothing, thereby reducing the risk of physical wear or blockage of the negative electrode plate 230 surface by large particles. It also protects the first fan 220 from direct impact or entanglement by large particles. The filter element also provides some protection for the functional modules 300 within the auxiliary air duct 210. Furthermore, the filter element located on the air inlet side of the auxiliary air duct 210 is convenient for user maintenance and replacement.

[0058] In one optional implementation, combined with Figure 1 and Figure 3 As shown, an air guide 250 is provided at the connection between the auxiliary air duct 210 and the drying air duct 110 to guide the airflow blown out of the auxiliary air duct 210, reduce flow resistance, and reduce wind resistance. The number and shape of the air guide 250 can be designed as needed, and this embodiment does not impose specific limitations on them.

[0059] In one optional implementation, combined with Figure 1 and Figure 3 As shown, there are multiple functional modules 300, and these multiple functional modules 300 are arranged sequentially and at intervals along the air intake direction of the auxiliary air duct 210. On the one hand, this reduces the space occupied and improves the space utilization rate; on the other hand, different functional modules 300 can be selected according to actual usage needs, thereby improving the user experience.

[0060] In one optional implementation, combined with Figure 1 and Figure 2 As shown, the garment processing equipment also includes a drying fan 500, which is installed in the drying duct 110 and is used to drive the airflow within the drying duct 110.

[0061] In this embodiment, the function of the drying fan 500 is to generate power to drive the air to circulate in the drying duct 110, thereby improving the drying efficiency. At the same time, the airflow can drive the second fan 400 in the drying duct 110 to rotate, and then drive the first fan 220 to rotate through the transmission component 410.

[0062] In one optional implementation, combined with Figure 1 and Figure 3 As shown, functional module 300 includes at least one of a misting wrinkle-removing module 310, a negative ion generator 320, and a misting aromatherapy module 330. The misting wrinkle-removing module 310 helps reduce wrinkles in clothing during or after drying by spraying fine water mist or steam, making the clothing smoother. The negative ion generator 320 releases negative ions, which may help remove static electricity from clothing, making it softer. The misting aromatherapy module 330 allows the addition of aromatherapy liquid, which is then evenly sprayed onto the clothing through misting, giving the dried clothing a pleasant fragrance.

[0063] The garment processing equipment provided in this application includes a device body 100, an air duct 200, a functional module 300, and a first fan 220. The device body 100 forms a drying air duct 110. The air duct 200 is disposed in the device body 100 and forms an auxiliary air duct 210. The air inlet end of the auxiliary air duct 210 is connected to the outside, and the air outlet end of the auxiliary air duct 210 is connected to the drying air duct 110. The functional module 300 is disposed in the auxiliary air duct 210. The first fan 220 is disposed at the air inlet end of the auxiliary air duct 210. By placing the functional module 300 in the auxiliary air duct 210, a certain degree of isolation is formed between it and the drying air duct 110, reducing the possibility of lint accumulation. At the same time, during equipment operation, negative pressure is generated in the drying air duct 110 due to airflow. This results in a relatively high air pressure in the auxiliary air duct 210. Based on this pressure difference, any small amount of lint, dust, or other impurities that may be generated in the auxiliary air duct 210 will naturally flow into the lower-pressure drying air duct 110 under the influence of air pressure, instead of accumulating on the functional module 300 within the auxiliary air duct 210. This effectively avoids the problem of blockage or performance degradation of the functional module 300 due to dirt accumulation, significantly improving its reliability and service life. The placement of the first fan 220 also helps to blow lint from the auxiliary air duct 210 into the drying air duct 110.

[0064] It is understood that the clothing processing equipment in this embodiment may include, but is not limited to, household appliances such as dryers, tumble dryers, and washer-dryer combos.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate this application and are not intended to limit this application. Although this application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications, or equivalent substitutions of the technical solutions of this application do not depart from the spirit and scope of the technical solutions of this application and should all be covered within the protection scope of this application.
