[0033] In related technologies, cleaning equipment is used to clean stains and food residues on tableware. Cleaning equipment generally uses circulating water, and a filtering device is provided inside the cleaning equipment to filter the residues in the cleaning liquid. In some existing technologies, after the filtering device filters the impurities in the cleaning liquid, when the filtered impurities flow to the next level, the filtered impurities may flow back into the filtering device, thereby causing secondary pollution to the filtered cleaning liquid.

[0034] Reference below Figures 1-6 A filtering device for cleaning equipment according to an embodiment of the present invention is described.

[0035] According to the utility model, the filtering device 100 for cleaning equipment includes: a base 11, a discharge device 13 and a filter mechanism 21. The base 11 is formed with a centrifugal chamber and a slag collecting chamber 102 that are connected to each other, and the centrifugal chamber 101 is suitable for being connected to the cleaning equipment; the discharge device 13 is formed with a discharge channel that is connected to the slag collecting chamber 102; the filter mechanism 21 is arranged in the centrifugal chamber, and the filter mechanism 21 is suitable for filtering impurities flowing through the centrifugal chamber, and the upstream side of the filter mechanism 21 is connected with the slag collecting chamber 102 and the slag collecting chamber 102 is suitable for collecting impurities; wherein a centrifugal chamber outlet 204 that connects the centrifugal chamber with the slag collecting chamber 102 is formed on the base 11, and the base 11 also forms a centrifugal chamber inlet 201 of the centrifugal chamber, and the position of the centrifugal chamber outlet 204 is higher than the centrifugal chamber inlet 201.

[0036] In some specific embodiments, the filtering device 100 is composed of a base 11, a discharge device 13 and a filtering mechanism 21. A centrifugal chamber and a slag collecting chamber 102 are provided on the base 11. The base 11 is also formed with a centrifugal chamber inlet 201 of the centrifugal chamber. The centrifugal chamber is connected to the cleaning equipment through the centrifugal chamber inlet 201. The cleaning liquid in the cleaning process of the cleaning equipment can flow into the centrifugal chamber through the centrifugal chamber inlet 201. A filtering mechanism 21 is also provided in the centrifugal chamber. The filtering mechanism 21 can be used to filter impurities in the cleaning liquid in the centrifugal chamber. A centrifugal outlet is also formed on the base 11. The upstream side of the filtering mechanism 21 is connected to the slag collecting chamber 102 through the centrifugal outlet. The filtered impurities in the centrifugal chamber can be connected and discharged into the slag collecting chamber 102 through the centrifugal outlet, and the position of the centrifugal chamber outlet 204 is set higher than the position of the centrifugal chamber inlet 201 to ensure that the filtered impurities can only flow from the centrifugal chamber into the slag collecting chamber 102, and the filtered impurities in the slag collecting chamber 102 cannot flow back to the centrifugal chamber, preventing the cleaning liquid in the centrifugal chamber from being contaminated secondary, thereby improving the cleaning effect of the cleaning equipment. In addition, the slag collecting chamber 102 is also connected to the discharge device 13 through the discharge channel formed in the discharge device 13, and the filtered impurities in the slag collecting chamber 102 can be discharged to the outside through the discharge channel, thereby ensuring the cleanliness of the slag collecting chamber 102. According to the filtering device 100 of the present invention, a centrifugal chamber and a slag collecting chamber 102 that are connected to each other are provided on the base 11. The centrifugal chamber can be used to clean impurities in the cleaning liquid, and the slag collecting chamber 102 can be used to collect filtered impurities flowing out of the centrifugal chamber. A centrifugal chamber inlet 201 and a centrifugal chamber outlet 204 are also formed on the base 11. The centrifugal chamber is connected to the cleaning equipment through the centrifugal chamber inlet 201, and the centrifugal chamber is connected to the slag collecting chamber 102 through the centrifugal chamber outlet 204. The position of the centrifugal chamber outlet 204 is set to be higher than the position of the centrifugal chamber inlet 201 to ensure that filtered impurities can only flow from the centrifugal chamber into the slag collecting chamber 102, and the filtered impurities in the slag collecting chamber 102 cannot flow back to the centrifugal chamber, thereby preventing the cleaning liquid in the centrifugal chamber from being secondary contamination and improving the cleaning effect of the cleaning equipment.

[0037] According to some embodiments of the present invention, the distance between the centrifugal chamber outlet 204 and the bottom surface of the centrifugal chamber is h1, the height of the centrifugal chamber is h2, and the following condition is satisfied: h1 / h2≥1 / 2.

[0038] When h1 and h2 satisfy the above relationship, it can ensure that the filtered impurities can only flow from the centrifugal chamber into the slag collecting chamber 102, and the filtered impurities in the slag collecting chamber 102 cannot flow back to the centrifugal chamber, preventing the cleaning liquid in the centrifugal chamber from being secondary contaminated, thereby improving the cleaning effect of the cleaning equipment.

[0039] According to some embodiments of the present invention, the centrifugal chamber is constructed as a rotating body, and a slag collecting channel is formed between the centrifugal chamber and the slag collecting chamber 102. The slag collecting channel is connected to the centrifugal chamber outlet 204, and the filtered impurities in the centrifugal chamber can be discharged into the slag collecting chamber 102 through the slag collecting channel. Since the centrifugal chamber is constructed as a rotating body, when the filter mechanism 21 rotates at high speed in the centrifugal chamber, the water flow can drive the filtered impurities to flow around the centrifugal chamber under the action of centrifugal force. When flowing to the centrifugal chamber outlet 204, since at least part of the slag collecting channel extends along the tangential direction of the centrifugal chamber body, the extension direction of the slag collecting channel is the same as the water flow direction, so that the water flow encounters little resistance when flowing in the slag collecting channel, thereby improving the smoothness of the movement of filtered impurities in the slag collecting channel.

[0040] According to some embodiments of the present invention, the discharge device 13 includes: a circulation pump 23 and a recoil member 31, the inlet of the circulation pump 23 is connected to the downstream side of the filter mechanism 21; the recoil member 31 is arranged in the centrifugal chamber 101, the recoil member 31 is arranged on the downstream side of the filter mechanism 21 and is formed with a recoil port 301 facing the filter mechanism 21, and the recoil member 31 is connected to the outlet of the circulation pump 23 so as to be suitable for spraying toward the filter mechanism 21.

[0041] In some specific embodiments, the discharge device 13 is composed of a circulation pump 23 and a backwash member 31. The inlet of the circulation pump 23 is connected to the downstream side of the filter mechanism 21. The cleaning liquid filtered by the filter mechanism 21 in the centrifugal chamber 101 can directly enter the circulation pump 23 through the inlet of the circulation pump 23, thereby increasing the flow rate of the cleaning liquid between the circulation pump 23 and the centrifugal chamber 101 and improving the circulation efficiency of the cleaning liquid. The backwash member 31 is accommodated in the centrifugal chamber 101 and is located on the downstream side of the filter mechanism 21. The backwash member 31 is connected to the outlet of the circulation pump 23. The cleaning liquid filtered in the centrifugal chamber 101 enters the inlet of the circulation pump 23. In the process of the cleaning liquid flowing from the inlet of the circulation pump 23 to the outlet of the circulation pump 23, at least part of the cleaning liquid will flow into the recoil member 31 from the connection between the recoil member 31 and the outlet of the circulation pump 23. A recoil port 301 open toward the filter mechanism 21 is formed on the recoil member 31. The cleaning liquid flowing into the recoil member 31 can be sprayed onto the filter mechanism 21 from the recoil port 301 to remove the filtered impurities adhering to the surface of the filter mechanism 21, reduce the possibility of clogging of the filter mechanism 21, improve the cleanliness and water permeability of the filter mechanism 21, reduce the loss of cleaning liquid, and improve the filtration efficiency and filtration effect of the filter mechanism 21.

[0042] According to some embodiments of the present invention, an outlet connected to the circulation pump 23 is formed at the bottom of the centrifugal chamber 101, and the cleaning liquid filtered by the filter mechanism 21 in the centrifugal chamber can directly flow into the circulation pump 23 through the outlet, reducing water loss and improving the efficiency of water circulation. The filter mechanism 21 is constructed as a cylinder open toward the bottom, which can increase the filtering area of ​​the filter mechanism 21 and improve the filtering effect on the cleaning liquid. At the same time, it can also optimize the flow direction of the cleaning liquid to ensure that the cleaning liquid can pass through the filter mechanism 21 more effectively, thereby improving the filtering effect of the filter mechanism 21. An upstream side connected to the slag collecting chamber 102 is formed between the outer periphery of the filter mechanism 21 and the inner wall of the centrifugal chamber. The high-speed rotation of the filter mechanism 21 drives the cleaning liquid containing filtered impurities to flow toward the upstream side, and enters the slag collecting chamber 102 through the centrifugal chamber outlet 204 set on the upstream side.

[0043] According to some embodiments of the present invention, the filter device 100 also includes: a first disturbance blade, which is formed on the outer peripheral wall of the filter mechanism 21 and is located at the bottom of the outer peripheral wall of the filter mechanism 21. The first disturbance blade can rotate together with the filter mechanism 21. When the filter mechanism 21 rotates, the first disturbance blade can push the filtered impurities to flow toward the centrifugal chamber outlet 204, thereby helping the filtered impurities to flow smoothly into the slag collection channel. At the same time, the first disturbance blade can stir the surrounding cleaning liquid when rotating, generating a vortex effect, driving the water flow to flush the surface of the filter mechanism 21, preventing the filtered impurities from accumulating on the filter mechanism 21, and reducing the possibility of clogging of the filter mechanism 21. The cleanliness and water permeability of the filter mechanism 21 are improved, the loss of cleaning liquid is reduced, and the filtering efficiency and filtering effect of the filter mechanism 21 are improved. The first disturbance blade is constructed to surround the outer periphery of the filter mechanism 21 and is arranged at intervals. Each first disturbance blade is inclined relative to the axis of the filter mechanism 21, reducing mutual interference between the multiple first disturbance blades, avoiding the clogging of filtered impurities between two adjacent first disturbance blades, improving the rotation efficiency of the first disturbance blades, and ensuring that the water flow can be evenly distributed, avoiding the concentration of water flow in a certain part, ensuring that the first disturbance blade can effectively stir the water flow when rotating, and improving the cleaning effect of the filter mechanism 21.

[0044] According to some embodiments of the present invention, a first outlet and a second outlet 203 are formed in the slag collecting chamber 102, the first outlet is connected to the inlet of the circulating pump 23 and the first outlet is provided with a slag collecting filter 22, the second outlet 203 is connected to the outside world, and the second outlet 203 is provided with a one-way valve 24 that conducts in one direction in the discharge direction of the slag collecting chamber 102.

[0045] In some specific embodiments, a first outlet and a second outlet 203 are provided in the slag collecting chamber 102. The first outlet connects the slag collecting chamber 102 with the inlet of the circulation pump 23. The cleaning liquid in the slag collecting chamber 102 can enter the circulation pump 23 from the first outlet, thereby realizing the recycling of the cleaning liquid. A slag collecting filter 22 is provided on the upper cover of the first outlet. The slag collecting filter 22 can be used to intercept larger impurities in the cleaning liquid in the slag collecting chamber 102, ensuring that the cleaning liquid entering the circulation pump 23 from the slag collecting chamber 102 is relatively clean, effectively preventing the circulation pump 23 from being blocked or damaged, and ensuring the safe operation of the cleaning equipment. Stability, the second outlet 203 connects the slag collecting chamber 102 with the outside world, and the filtered impurities in the slag collecting chamber 102 can be discharged to the outside world through the second outlet 203. A one-way valve 24 is provided in the second outlet 203, and the one-way valve 24 is conducted in the direction of discharging the slag collecting chamber 102 to ensure that the filtered impurities in the slag collecting chamber 102 can only flow in one direction (i.e., flow out from the slag collecting chamber 102), preventing the filtered impurities discharged to the outside world from the slag collecting chamber 102 from flowing back to the slag collecting chamber 102, avoiding secondary contamination of the cleaning liquid in the slag collecting chamber 102, and improving the cleaning effect of the cleaning equipment.

[0046] According to some embodiments of the present invention, second disturbance blades 25 are formed on the slag collecting filter screen 22 . The second disturbance blades 25 are configured to be multiple and spaced apart and arranged on the outer periphery of the slag collecting filter screen 22 .

[0047] In some specific embodiments, the second disturbance blades 25 are formed on the outer periphery of the slag filter 22 and are located at the bottom of the slag filter 22. The second disturbance blades 25 are constructed as a plurality of them arranged at intervals. The second disturbance blades 25 can rotate together with the slag filter 22 or rotate alone. When rotating, the second disturbance blades 25 can stir the filtered impurities in the slag chamber 102 and mix them with water, so as to facilitate better discharge of filtered impurities. When the slag filter 22 rotates, the second disturbance blades 25 can push the filtered impurities to move toward the second outlet 203, thereby helping the filtered impurities to be smoothly discharged from the second outlet 203 to the outside world. At the same time, the rotation of the second disturbance blades 25 can stir the surrounding water flow, generate a vortex effect and drive the water flow to flush the surface of the slag filter 22, prevent the filtered impurities from accumulating on the filter screen and remove the filtered impurities adhering to the surface of the slag filter 22, reduce the possibility of clogging of the slag filter 22, improve the cleanliness of the slag filter 22, and improve the filtration efficiency and filtration effect of the slag filter.

[0048] According to some embodiments of the present invention, the outlet 202 of the slag collecting channel is higher than the first outlet and the second outlet 203 .

[0049] In some specific embodiments, the slag collecting channel is connected to the centrifugal chamber, and the outlet 202 of the slag collecting channel is set at a position higher than the setting positions of the first outlet and the second outlet 203, respectively, to prevent the filtered impurities in the slag collecting chamber 102 from flowing back into the slag collecting channel through the outlet of the slag collecting channel, and then flowing back into the centrifugal chamber through the slag collecting channel, thereby avoiding secondary contamination of the cleaning liquid in the centrifugal chamber and improving the cleaning effect of the cleaning equipment.

[0050] According to some embodiments of the present invention, the first outlet and the second outlet 203 are respectively provided at the bottom of the slag collecting chamber 102 , and the slag collecting filter 22 is cylindrical in structure and the bottom is connected to the first outlet.

[0051] In some specific embodiments, since the cleaning liquid that flows into the slag collecting chamber 102 through the slag collecting channel after filtration by the filter mechanism 21 contains more filtered impurities, the cleaning liquid at this time is usually heavier, and the filtered impurities in the cleaning liquid tend to be deposited at the bottom of the slag collecting chamber 102. Setting the second outlet 203 on the bottom side wall of the slag collecting chamber 102 can ensure that the filtered impurities can be smoothly discharged to the outside through the second outlet 203. Setting the first outlet at the bottom of the slag collecting chamber 102 can reduce the obstruction in the flow path of the cleaning liquid, so that the cleaning liquid filtered by the slag collecting filter 22 can smoothly flow into the circulation pump 23 through the first outlet.

[0052] In addition, the slag filter 22 is constructed in a cylindrical shape, which can, on the one hand, increase the area of ​​the slag filter 22 and improve the filtering efficiency of the slag filter 22, and on the other hand, optimize the flow direction of the cleaning liquid, ensuring that the cleaning liquid can pass through the slag filter 22 more effectively, thereby improving the filtering effect of the slag filter 22. The bottom of the slag filter 22 is connected to the first outlet, and the cleaning liquid filtered by the slag filter 22 can flow directly from the first outlet into the circulation pump 23, simplifying the cleaning liquid discharge process and improving the efficiency of the cleaning liquid circulation flow in the cleaning equipment. According to some embodiments of the present invention, the filtering device 100 also includes: a driving device, which is connected to the filtering mechanism 21 and / or the slag filter 22 to be suitable for driving the filtering mechanism 21 and / or the slag filter 22 to rotate.

[0053] In some specific embodiments, a driving device is further provided in the filter device 100, and the driving device can be connected to the filter mechanism 21. The driving device can drive the filter mechanism 21 to rotate at high speed. The high-speed rotation of the filter mechanism 21 generates centrifugal force to separate the filtered impurities attached to the surface of the filter mechanism 21, thereby ensuring the water permeability of the filter mechanism 21, thereby improving the filtering efficiency and effect of the filter mechanism 21.

[0054] The driving device can also be connected to the slag filter 22 and drive the slag filter 22 to rotate at high speed, and drive the second disturbance blade 25 set at the bottom of the slag filter 22 to rotate to stir the water in the slag chamber 102. The water flushes the surface of the slag filter 22 to separate the filtered impurities from the slag filter 22, and pushes the filtered impurities to move toward the second outlet 203, so as to facilitate the discharge of filtered impurities to the outside world.

[0055] The cleaning device according to the present invention is briefly described below.

[0056] The cleaning device according to the present invention has the filtering device 100 described in any one of the above embodiments. Since the cleaning device according to the present invention is also provided with a device body and a filter cup 12, the base 11 is integrated in the device body, and the device body is formed with a cleaning space and a filter cavity 103. The filter cavity 103 is located below the cleaning space, and the bottom of the cleaning space is connected to the filter cavity 103, and the side wall of the filter cavity 103 is connected to the side wall of the centrifugal cavity; the filter cup 12 is installed in the filter cavity 103, and the filter cup 12 is open toward the cleaning space. The filter cup can clean larger impurities in the liquid, so the cleaning device according to the present application has a better cleaning effect on tableware.
