Small particles of residue will enter the circulating water and be brought to the tableware, causing secondary contamination of the tableware.

[0039] Reference below Figures 1-4 A cleaning device 1 according to an embodiment of the present invention is described.

[0040] like Figures 1-4As shown, the cleaning device 1 according to the present invention includes: a shell 10, a filter 20, a circulation pump 30 and a recoil member 40, and a first cavity 10a and a second cavity 10b that are connected to each other are formed in the shell 10; the filter 20 is arranged in the first cavity 10a and the upstream side of the filter 20 is connected to the second cavity 10b; the inlet of the circulation pump 30 is connected to the downstream side of the filter 20; the recoil member 40 is arranged in the first cavity 10a and is connected to the outlet of the circulation pump 30, and a spray hole 40a open to the filter 20 is provided on the recoil member 40. Specifically, when the cleaning device 1 cleans the object to be cleaned, the flow of washing water will drive the impurities on the object to be cleaned to flow, and the washing water carrying impurities flows from the second cavity 10b toward the first cavity 10a. Here, the filter 20 located in the first cavity 10a can filter the washing water, and the washing water will flow from the upstream side of the filter 20 to the downstream side. The larger impurities in the washing water will be blocked by the filter 20 on the upstream side of the filter 20, and the smaller impurities will flow to the downstream side of the filter 20 with the washing water, and flow toward the recoil component 40 under the action of the circulation pump 30. The recoil component 40 sprays this part of the washing water toward the filter 20 to use the washing water to flush the filter 20, thereby flushing away the impurities attached to the filter 20, ensuring the water permeability of the filter 20.

[0041] According to the present invention, the cleaning device 1 is provided with a recoil component 40 to use washing water to flush the filter 20, flushing away impurities attached to the filter 20, ensuring the water permeability of the filter 20, and saving water resources while improving the cleaning effect of the cleaning device 1 on the object to be cleaned.

[0042] In some embodiments, a filter element may also be provided in the second cavity 10b to perform preliminary filtration on the washing water to reduce impurities carried by the washing water. The filter net 20 located in the first cavity 10a can further filter the washing water, thereby improving the filtering effect of the cleaning device 1 on impurities.

[0043] In some embodiments, the second cavity 10b is connected to the first cavity 10a through a communication port 10c on the housing 10, and the washing water carrying impurities in the second cavity 10b can flow toward the first cavity 10a through the communication port 10c.

[0044] It will be appreciated that, under the pumping action of the circulation pump 30, wash water enters the recoil member 40 at a certain speed and is sprayed onto the filter 20 through the spray hole 40a of the recoil member 40. The spray hole 40a on the recoil member 40 opens toward the filter 20. In some embodiments, the spray hole 40a may be directly opposite the filter 20, and the wash water sprayed from the spray hole 40a can be sprayed directly onto the filter 20. In other embodiments, the spray hole 40a may not be directly opposite the filter 20, and the wash water sprayed from the spray hole 40a may be sprayed onto the filter 20 along a parabolic trajectory. The design can be tailored to actual needs.

[0045] In some embodiments, the spray hole can be in various forms such as fan-shaped, cone-shaped, and surface-shaped.

[0046] According to some embodiments of the present invention, the radial distance between the recoil member 40 and the filter 20 is d, and satisfies the following: d ≥ 3 mm. It is understood that to prevent impurities on the filter 20 from splashing onto the recoil member 40, the recoil member 40 and the filter 20 are spaced a certain distance apart to ensure the cleanliness of the spray holes 40a on the recoil member 40, thereby ensuring the cleanliness of the wash water sprayed from the spray holes 40a and reducing contamination of the wash water by impurities. In some embodiments, the location of the recoil member 40 is related to the size of the interior space of the filter 20, and the radial distance between the recoil member 40 and the filter 20 is designed based on the size of the interior space of the filter 20. The specific location of the recoil member 40 and the specific radial distance between the recoil member 40 and the filter 20 are not limited herein.

[0047] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, the recoil member 40 extends axially along the filter 20, and the spray holes 40a are located on the surface of the recoil member 40 facing the filter 20. In some embodiments, the filter 20 is annular, and the recoil member 40 can be disposed on the upstream side or the downstream side of the filter 20. The recoil member 40 extends axially along the filter 20, allowing the spray holes 40a to spray the filter 20 axially, thereby increasing the coverage area of ​​the wash water sprayed on the filter 20 and improving the cleaning effect of the wash water on the filter 20.

[0048] According to some embodiments of the present invention, Figure 2-Figure 4As shown, the recoil member 40 is located on the downstream side of the filter 20. It is understood that after the filter 20 filters the wash water, larger impurities in the wash water may adhere to the surface of the filter 20 located on the upstream side. At this time, the recoil member 40 sprays wash water toward the filter 20 on the downstream side of the filter 20 to flush down the impurities attached to the surface of the filter 20 located on the upstream side, thereby separating the impurities from the filter 20. Positioning the recoil member 40 on the downstream side of the filter 20 also prevents impurities from contaminating the recoil member 40, thereby preventing impurities from clogging the spray holes 40a of the recoil member 40. This prevents the recoil member 40 from re-contaminating the filter 20, thereby ensuring the recoil member 40's cleaning effect on the filter 20.

[0049] According to some embodiments of the present invention, the spray hole 40a extends along the axial direction of the filter screen 20. At this time, the washing water sprayed from the spray hole 40a can be sprayed on the filter screen 20 along the axial direction of the filter screen 20 to fully spray the filter screen 20, further improving the cleaning effect of the recoil component 40 on the filter screen 20.

[0050] In some embodiments, the recoil member 40 is provided with a spray hole 40 a extending axially along the filter screen 20 . The water pressure of the single hole is large, and the force exerted on the impurities is also greater, so that the impurities are effectively separated from the filter screen 20 .

[0051] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, the spray holes 40a are constructed in a plurality, and the plurality of spray holes 40a are spaced apart in the axial direction of the filter screen 20. The plurality of spray holes 40a can spray water alternately or simultaneously to fully spray the filter screen 20, and the multi-hole spraying form sprays more comprehensively.

[0052] In some embodiments, as Figure 4 As shown, the recoil member 40 is located inside the annular filter 20, and the outer circumferential surface of the recoil member 40 is opposite to the inner surface of the annular filter 20. The outer circumferential surface of the recoil member 40 is provided with a plurality of spray holes 40a at intervals in the circumferential direction to spray the filter 20 along the circumference of the filter 20.

[0053] In some embodiments, as Figure 4 As shown, the outer circumferential surface of the recoil member 40 is provided with a plurality of groups of spray holes 40 a spaced apart in the circumferential direction, and each group of spray holes 40 a includes a plurality of spray holes spaced apart in the axial direction, so as to spray along the circumferential and axial directions of the filter screen 20 to clean the filter screen 20 more comprehensively.

[0054] According to some embodiments of the present invention, the spraying areas of at least two spray holes 40a overlap. This may be the case with two spray holes 40a or more spray holes 40a. Furthermore, this may be the case with adjacent spray holes 40a or with spaced spray holes 40a. By designing the multiple spray holes 40a so that the spraying areas of at least two of them overlap, the wash water sprayed by the spray holes 40a can be sprayed multiple times on portions of the filter 20, thereby improving the cleaning effect of the filter 20.

[0055] According to some embodiments of the present invention, the plurality of spray holes 40a include at least a first hole, a second hole, and a third hole. The spray areas of the first hole, the second hole, and the third hole cover heights h1, h2, and h3, respectively, in the axial direction of the filter screen 20. The axial height of the filter screen 20 is H, and the following conditions are satisfied: [h1∪h2∪h3]≥H. In some embodiments, the first hole, the second hole, and the third hole can be arranged sequentially along the axial direction of the filter screen 20. In this case, the spray areas of the first hole and the second hole can overlap, the spray areas of the second hole and the third hole can overlap, or the spray areas of the first hole, the second hole, and the third hole can all overlap. It is sufficient to ensure that the wash water sprayed from the plurality of spray holes 40a can cover the filter screen 20, that is, to satisfy the following conditions: [h1∪h2∪h3]≥H, thereby achieving sufficient spraying of the filter screen 20.

[0056] According to some embodiments of the present invention, the spraying area of ​​the spray hole 40a covers the filter screen 20 at a height h in the axial direction, the height of the filter screen 20 in the axial direction is H, and satisfies: h≥H, so that the washing water sprayed by the spray hole 40a can cover the filter screen 20, thereby achieving sufficient spraying of the filter screen 20.

[0057] According to some embodiments of the present invention, Figure 2-Figure 3 As shown, the recoil members 40 are constructed in plurality, and the plurality of recoil members 40 are arranged at intervals in the circumferential direction of the filter screen 20. At this time, the plurality of recoil members 40 can spray at the same time to comprehensively clean the filter screen 20 in the circumferential direction of the filter screen 20, or the plurality of recoil members 40 spray intermittently to improve the cleaning efficiency of the filter screen 20.

[0058] According to some embodiments of the present invention, Figure 2-Figure 3 As shown, the recoil members 40 have different sizes in the axial direction of the filter 20. The recoil members 40 of different sizes can take into account different positions and different heights of the filter 20 to clean the filter 20 more comprehensively. In addition, the longer recoil member 40 can spray to a higher position of the filter 20. The spraying range of the longer recoil member 40 and the shorter recoil member 40 in the axial direction of the filter 20 has a certain overlap, which can improve the spraying effect on the filter 20.

[0059] According to some embodiments of the present invention, Figure 2-Figure 3 As shown, the spray holes 40a on at least two recoil members 40 are staggered in the axial direction of the filter 20. The spray holes 40a at different heights can take care of different positions and heights of the filter 20 to clean the filter 20 more comprehensively.

[0060] According to some embodiments of the present invention, Figure 1 As shown, the cleaning device 1 further includes a drive motor 50, which is connected to the filter 20 and is suitable for driving the filter 20 to rotate. Here, in some embodiments, the recoil member 40 is located inside the annular filter 20, and the outer peripheral surface of the recoil member 40 is provided with at least one spray hole 40a. The filter 20 is rotatable so that the washing water sprayed by the recoil member 40 can be sprayed along the circumference of the filter 20, thereby more comprehensively cleaning the filter 20.

[0061] At the same time, the filter 20 rotates, so that the impurities attached to the filter 20 are separated from the filter 20 under the action of centrifugation, and the recoil component 40 sprays washing water to the filter 20 to further separate the impurities from the filter 20. The filter 20 can be fully and comprehensively cleaned, thereby improving the cleaning effect of the filter 20, thereby improving the cleaning effect of the cleaning equipment 1.

[0062] As well as Figure 1-Figure 2 As shown, a fixed cover 11 is provided on the shell 10 to connect with the filter 20, and the filter 20 is fixed on the fixed cover 11. The fixed cover 11 is connected to the drive shaft 52. The drive shaft 52 is arranged parallel to the drive motor 50. The drive motor 50 drives the drive shaft 52 to rotate through the transmission gear 51, so that the drive shaft 52 can drive the fixed cover 11 to rotate, thereby driving the filter 20 to rotate.

[0063] According to some embodiments of the present invention, Figure 1-Figure 2 As shown, the cleaning device 1 also includes a drain pump 60, the inlet of the drain pump 60 is connected to the upstream side of the filter 20, and the outlet of the drain pump 60 is connected to the outside of the shell 10. At this time, the washing water carrying more impurities can be directly discharged from the cleaning device 1, which can reduce the amount of impurities during the water circulation process, avoid impurities from re-entering the circulating water, and avoid contaminating the filter 20.

[0064] In some embodiments, the inlet of the drain pump 60 is also communicated with the second cavity 10 b , so as to discharge the excess wash water carrying impurities from the second cavity 10 b .

[0065] To sum up, according to the cleaning equipment 1 of the present invention, washing water is used to flush the filter 20, thereby washing away impurities attached to the filter 20, ensuring the water permeability of the filter 20, reducing the amount of impurities in the washing water, and saving water resources while improving the cleaning effect of the cleaning equipment 1 on the object to be cleaned.
