Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of clothes dryers, and more precisely to a filter cleaning structure and a clothes dryer. Background Technology
[0002] After clothes in a dryer drum are dried by the drying air, fine lint and fuzz are produced. When the dryer exhausts air, it easily expels these lint and fuzz into the air. Furthermore, the lint circulates with the drying air in the duct, causing a significant amount of lint to adhere to the clothes. Therefore, most dryers are equipped with a lint filter. The hot drying air continuously passes through the clothes, blows onto the filter, and then enters the duct. The lint is trapped on the filter, and after prolonged use, a large amount of lint accumulates on the filter, requiring regular removal and cleaning.
[0003] Due to the drying effect of hot air, the lint and fuzz collected by the filter are very dry. When the filter is removed, the lint tends to fly everywhere and has a strong odor, affecting the user experience. To prevent lint from flying everywhere when the filter is removed, it needs to be moistened. In the past, users usually had to manually moisten the filter using a spray bottle or similar tool, which was cumbersome, easy to forget, and inconvenient for users.
[0004] In summary, there is a need in the art for a structure that can wet the filter screen while it is being removed, in order to reduce lint scattering and facilitate operation. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1 to 5 As shown, this application discloses a filter cleaning structure installed in the front cover 1 of a dryer. The filter cleaning structure includes a filter 2 and water spray components 3 disposed on both sides of the filter 2. The filter 2 is detachably installed in the front cover 1, and the side of the filter 2 exposed from the front cover 1 has filter holes 21 for collecting lint and fuzz. The two opposite sides of the filter 2 have protrusions 23 and several through holes 22, respectively. The water spray components 3 are installed inside the front cover 1, and are respectively disposed corresponding to the protrusions 23. The water spray components 3 have nozzles 32 and buttons 33 facing the protrusions 23. The water spray components 3 are filled with liquid. When the button 33 is squeezed, the nozzles 32 spray liquid toward the side of the filter 2. When the filter 2 is removed, the protrusions 23 squeeze the button 33, and the nozzles 32 spray liquid toward the side of the filter 2. The liquid enters the interior of the filter 2 through the through holes 22, wetting the lint and fuzz inside the filter 2. The filter cleaning structure effectively prevents lint and fuzz from flying around when the filter 2 is removed, while also reducing the odor of lint and fuzz. It can also wet the filter 2 while it is being removed, without requiring any additional operation from the user. In addition, the water spray assembly 3 does not require an external power supply, has a simple and stable structure, requires no additional wiring, and is easy to maintain.
[0025] For details, see Figure 3The water spray assembly 3 has a water storage chamber 30 inside, and a removable sealing cover 300 is installed on the top of the water spray assembly 3. The sealing cover 300 closes the water storage chamber 30 from the top of the water spray assembly 3, with the sealing cover 300 protruding from the front cover 1. The water storage chamber 30 can store water or aromatic water. When the liquid in the water storage chamber 30 is depleted, the user can remove the sealing cover 300 and add replenishing water or aromatic water from the top of the water spray assembly 3. The installation position of the sealing cover 300 and the operating position of the filter screen 2 are on the same plane, allowing the user to easily and quickly complete the disassembly and cleaning of the filter screen and the replenishment of liquid in the water spray assembly 3.
[0026] The filter screen 2 has a filter chamber 20 inside, where the lint and fuzz collected by the filter screen 2 are located. The through hole 22 communicates with the filter chamber 20. The liquid sprayed by the water spray assembly 3 enters the filter chamber 20 through the through hole 22 and falls under the action of gravity, wetting the lint and fuzz in the filter chamber 20, preventing the lint and fuzz from spreading and reducing the odor of the lint and fuzz.
[0027] See Figure 3 and Figure 6 Nozzle 32 is connected to water storage chamber 30 via connecting pipe 31, which extends into the bottom of water storage chamber 30. Button 33 is integrated with connecting pipe 31. Pressing button 33 changes the pressure distribution in connecting pipe 31, causing it to absorb and transport liquid from water storage chamber 30 to nozzle 32. Preferably, connecting pipe 31 has a one-way valve 34, which allows flow from bottom to top of connecting pipe 31. The one-way valve 34 is located at the bottom of button 33. When button 33 is pressed, it compresses connecting pipe 31, increasing the flow velocity and decreasing the hydraulic pressure at the upper part of connecting pipe 31. The hydraulic pressure at the lower part of connecting pipe 31 is relatively greater, causing the liquid to move upward and be ejected from nozzle 32.
[0028] See Figure 7 Preferably, the boss 23 has several small holes 231, which communicate with the filter chamber 20. The liquid sprayed by the water spray assembly 3 can enter the filter chamber 20 through the small holes 231. By setting the small holes 231, the amount of liquid entering the filter chamber 20 is further increased, which helps to more effectively wet the lint and fibers in the filter chamber 20.
[0029] This application also discloses a clothes dryer using the aforementioned filter cleaning structure, wherein when the filter is removed for cleaning, the user does not need to manually wet the filter, making the operation convenient and quick.
[0030] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
