[0021] This utility model provides a filtration and water return device, including a cleaning tank 100 and a filtration and water return assembly. The filtration and water return assembly includes a treatment box 210, a filter frame 220, a filter screen 230, a water return pipe 240, a shielding structure, and a pull rod 270. The shielding structure includes a second spring 261 and a shielding block 262.

[0022] In this specific embodiment, the treatment box 210 is fixedly connected to the cleaning tank 100, and the treatment box 210 is located at the lower end of the cleaning tank 100. The filter frame 220 is slidably connected to the treatment box 210, and the filter frame 220 is located inside the treatment box 210. The filter screen 230 is fixedly connected to the filter frame 220, and the filter screen 230 is located inside the filter frame 220. The return water pipe 240 is fixedly connected to and communicates with the treatment box 210, and the return water pipe 240 is located at the bottom of the side of the treatment box 210. The cleaning tank 100 contains cleaning utensils for cleaning dishes. The treatment box 210 is installed at the bottom inner side of the cleaning tank 100. The treatment box 210 is used to install the filter frame 220, and the filter frame 220 is used to install the filter screen 230. The filter screen 230 is used to filter the water after cleaning. The return water pipe 240 is used to recycle the filtered water. After the vessel is cleaned through the cleaning chamber 100, the cleaning water falls onto the filter screen 230, which filters the water, blocking impurities such as chemical residues. The filtered cleaning water is then recycled through the return pipe 240. The filter screen 230 effectively prevents chemical residues from clogging the return pipe 240, thus solving the problem of water clogging the outlet due to chemical residues.

[0023] Furthermore, the filter frame 220 has a placement frame 221 on its inner side, and a positioning post 222 is provided on the placement frame 221. The filter screen 230 has a positioning groove 231. The filter screen 230 is placed on the placement frame 221, and the positioning post 222 passes through the interior of the positioning groove 231. The placement frame 221 is used to place the filter frame 220, and the positioning post 222 and the positioning groove 231 cooperate with each other to position the filter screen 230, so as to facilitate the installation of the filter screen 230. When installing the filter screen 230, the positioning groove 231 is aligned with the positioning post 222, so that the positioning post 222 is inserted into the positioning groove 231, thereby positioning the filter screen 230 for installation.

[0024] Specifically, a fixing structure is provided on the inner side of the filter frame 220. The fixing structure includes a first spring 251 and a fixing block 252. The two ends of the first spring 251 are fixedly connected to the filter frame 220 and the fixing block 252, respectively. The first spring 251 is located inside the filter frame 220. The fixing block 252 is slidably connected to the filter frame 220. The end of the fixing block 252 away from the first spring 251 extends out of the filter frame 220 and is located above the filter screen 230. The fixing structure is used to fix the filter screen 230 to the filter frame 220. The first spring 251 abuts against the fixing block 252, so that the end of the fixing block 252 away from the first spring 251 abuts against the filter frame 220 and is positioned above the end of the filter screen 230. The fixing block 252 and the placement bracket 221 cooperate to restrict the filter screen 230, preventing the filter screen 230 from wobbling up and down relative to the filter frame 220, thereby fixing the filter screen 230. When it is necessary to remove the filter screen 230, press the fixing block 252 so that the fixing block 252 no longer obstructs the filter screen 230, and the filter screen 230 can be removed from the placement bracket 221 for disassembly.

[0025] The processing box 210 has a mounting cavity 211. The two ends of the second spring 261 are fixedly connected to the processing box 210 and the blocking block 262, respectively. The second spring 261 is located inside the mounting cavity 211. The blocking block 262 is slidably connected to the processing box 210, and one end of the blocking block 262 away from the second spring 261 is in contact with the side of the filter frame 220. The blocking structure is used to fix the filter frame 220. The second spring 261 abuts against the blocking block 262, causing the end of the blocking block 262 away from the second spring 261 to abut out of the mounting cavity 211 to block the filter frame 220, thereby fixing the filter frame 220 inside the processing box 210. When the filter screen 230 needs to be disassembled, press the blocking block 262 so that the blocking block 262 moves into the mounting cavity 211, and the filter frame 220 can be slid out of the processing box 210. Press the fixing block 252 so that the fixing block 252 no longer blocks the filter screen 230, and the filter screen 230 can be removed from the placement rack 221 for disassembly.

[0026] In addition, the pull rod 270 is fixedly connected to the filter frame 220, and the pull rod 270 is located on the outside of the filter frame 220. The pull rod 270 is provided on the outside of the filter frame 220 so that the filter frame 220 can be pulled by the pull rod 270, thereby facilitating the removal of the filter frame 220 from the processing box 210.

[0027] When cleaning utensils using a filtration and water return device, the utensils are cleaned through the cleaning tank 100, and the cleaned water falls onto the filter screen 230. The filter screen 230 filters the cleaned water, blocking impurities such as chemical residues. The filtered cleaned water is then recycled through the return pipe 240. Because of the filter screen 230, chemical residues in the cleaned water are blocked, preventing clogging of the return pipe 240 and thus solving the problem. After cleaning, the water flows out through the outlet, but the water contains chemical residues, which can easily clog the outlet and affect its use. When it is necessary to disassemble the filter screen 230, press the blocking block 262 so that the blocking block 262 moves into the mounting cavity 211, and the filter frame 220 can be slid out of the treatment box 210. Press the fixing block 252 so that the fixing block 252 no longer blocks the filter screen 230, and the filter screen 230 can be removed from the placement rack 221 for disassembly.

[0028] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
