The cleaning device of the present invention does not require removal of the filter net during the process of cleaning the filtering device. In addition, it has a simple structure, is highly reliable, and is easy to inspect, repair, and maintain.

As shown in FIGS. 1-6, the present embodiment discloses a clothes processing apparatus. The clothes processing apparatus is a clothes dryer or an integrated washing and drying machine. As shown in FIG. 6, the clothes processing apparatus includes a filtering device 2 for filtering lint and a cleaning device 1 located thereabove. The clothes treating apparatus of this embodiment is provided with a lint filtering device to prevent lint from circulating in the drying system and clogging the air passages and other malfunctions. An opening is provided in the front support panel 3 of the clothes processing apparatus and the filtering device 2 is placed in said opening. Filtration device 2 is provided with a filter net or other filtration media to filter lint from the air within the clothes dryer.

The cleaning device 1 in the present invention is positioned above the filtering device 2 . As shown in FIG. 1, the cleaning device 1 includes a liquid supply port 101, a nozzle 105, and a guiding path that communicates these. The liquid introduced into the cleaning device 1 from the liquid supply port 101 flows out from the nozzle 105 after passing through the guiding path, and washes the filtering device. As a result, the lint adhering to the filter net 202 is washed away by the cleaning liquid. Also, the washing liquid may be directly discharged from the clothes dryer by the flow diversion device, or may be subjected to other treatments.

In order to save mounting space and improve the reliability of the equipment, the present invention takes full advantage of the panels of a conventional clothes treatment machine, making the front support panel of the clothes treatment machine part of the housing of the cleaning machine. As shown in FIGS. 2, 4 and 5, the cleaning device of the present invention includes a diverter plate 106. FIG. Said diverting plate 106 is laid on the front support panel 3 above the opening in the front support panel of the clothes treatment machine where the filtering device is located. Both the flow guide plate 106 and the front support panel 3 constitute the housing of the cleaning device 1 .

The guide plate 106 in the housing is provided with a guide groove recessed downward, and the main flow path 102 is formed by combining the guide groove and the front support panel 3 . An opening is formed in the guiding groove to form the liquid supply port 101 . The liquid supply port 101 is located on the main flow path 102 .

As shown in FIGS. 3 and 5, the guide path includes a main flow path 102 communicating with the liquid supply port 101, and a sub-guide path 103 communicating with the main flow path 102 and the nozzle 105, respectively. The main flow path 102 is located above the sub-flow path 103 . The sub-direct flow paths 103 of the cleaning device are a plurality of flow-direct paths installed at intervals and respectively communicating with the main flow path 102 . Each sub guide path 103 extends in the width direction of the cleaning device.

Furthermore, as shown in FIGS. 4 and 5, the guide plate 106 is provided with a plurality of protruding belt-like water stop ribs 104 at intervals. The water stop rib 104 is connected to the guide groove, which is the main flow path 102 , and extends in the width direction of the guide plate 106 . The protruding upper part of the water stop rib 104 is in close contact with the front support panel 3, and the adjacent water stop rib 104 and the front support panel 3 guide the liquid to flow out of the main flow path 102 as a sub-flow guide. A path 103 is formed. The sub-directing channel 103 opens at the bottom of the housing and forms a nozzle 105 of the cleaning device. The nozzle 105 is positioned above the filter and flushes the filter by spraying liquid toward the filter.

As shown, the nozzle 105 is flat and has a rectangular cross section with a large aspect ratio. The liquid ejected from the nozzle 105 has a wide coverage area and can cover most of the surface of the filtering device, so that the washing effect is excellent.

In this embodiment, the water cut-off ribs 104 combine the water flow of the main flow channel 102 into several water flows and discharge them from the nozzles 105 corresponding to the respective sub-drainage channels 103, so that the corresponding area of the filter device wash away. This improves washing accuracy. Such a design takes full advantage of the acceleration of water flow due to gravity. The main flow path is located above the sub-drainage path, and the liquid that has entered the cleaning device automatically flows into the nozzle due to the action of gravity. As a result, the cleaning liquid can be quickly ejected from the nozzles, and cleaning of the filtering device located below the cleaning device is realized.

As shown in FIGS. 2 and 5, one end of the main flow path 102 of the cleaning device of the present invention is bent downward in the longitudinal direction. As a result, both upper and lower ends having a drop are formed in the main flow path. The position at which the liquid supply port 101 communicates with the main flow path 102 is such that the length from the lower end of the main flow path 102 in the length direction of the main flow path 102 is from the liquid supply port 101 to the main flow path 102 is greater than the length to the top of the That is, after the liquid flows in from the liquid supply port 101, the length of the liquid flowing until it reaches both ends of the main flow path 102 is not the same, and the main flow path 102 bends relatively downward and the ends are closer to the lower side. The distance to the end of the flow path is longer. Such a design makes full use of the acceleration effect of gravity, and also fully considers the potential energy caused by the difference in elevation, and fully utilizes the advantage of the potential energy of the low-positioned end. , allowing the cleaning liquid to reach the far end. Furthermore, the flow velocity and flow rate are made uniform when the cleaning liquid reaches the upper and lower ends of the main flow path. This results in a uniform flow rate and velocity of water reaching each nozzle of the cleaning device, so that when the cleaning device flushes the filtering device, it is possible to achieve a consistent flushing effect across the width. Therefore, in the conventional washing device, the flow velocity of the water flow for washing is high at a position near the liquid supply port, and the washing effect is good, whereas the washing effect decreases at a position far from the liquid supply port. harm is avoided.

As shown in Figure 1, the filtering device 2 of the present invention comprises a frame structure. A reinforcing rib 201 is provided within the frame structure, and a filter net 202 covers the reinforcing rib 201 . The reinforcing ribs 201 of the present embodiment are provided in order to prevent lint from accumulating on the reinforcing ribs during the washing process and to reduce blind spots during washing, thereby making the washing action more thorough and comprehensive during cleaning. is the same as the flow direction of the liquid flowing out from the nozzle 105 of the cleaning device. Specifically, since the direction of water flowing out from the nozzle of the cleaning device in this embodiment is vertically downward, the direction of the reinforcing ribs is also set to be vertical. Also, both ends of the reinforcing rib are connected to both upper and lower sides of the frame of the filtering device. As a result, lint that has been washed off with washing water will not accumulate on the reinforcing ribs.

In other embodiments, the cleaning device included in the laundry treatment apparatus of the present invention is a separate assembly. The difference from the above embodiment is that it has an independent back panel and eliminates the need to combine it with the panel of the clothes dryer or the integrated washer/dryer. It is also mounted on the upper part of the filtering device in the same way, and the cleaning liquid is used to wash the filtering device.
