[0002] Cleaning equipment is usually provided with a filtering device for cleaning and filtering water flow so as to reuse the water flow. However, after long-term use, impurities (such as food residues, sediment or other foreign matters) are likely to adhere to the surface of the filtering device or block the flow channel of the water flow. Therefore, the cleaning equipment needs to be provided with a flow disturbing structure in the flow channel to change the flow form of the water flow so as to clean the filtering device or avoid blocking of the flow channel. Summary of the Utility Model

For this purpose, an object of the utility model is to provide a filtering device for a cleaning equipment. The filtering device of the utility model is provided with a flow disturbing component on the upstream side of the centrifugal filter screen. By stirring the water flow on the upstream side of the centrifugal filter screen through the flow disturbing component, the accumulation and blockage of impurities on the upstream side of the centrifugal filter screen and in the centrifugal cavity are avoided, so that the impurities can enter the slag collection cavity under the drive of the water flow, ensuring the filtering effect of the filtering device.

[0018] According to an embodiment of the present utility model, the spray holes of at least two of the backwashing members are staggered in the height direction.

[0019] The cleaning device according to the present utility model will be briefly described below.

[0020] The cleaning device according to the present utility model includes the filtering device in the above embodiment.

[0021] In summary, the cleaning device is provided with a filtering device. The filtering device is provided with a base located at the bottom of the cleaning device and a filter screen located on top of the base. The base is provided with a centrifugal chamber and a water collection chamber that is open towards the top. A filter cup is arranged in the water collection chamber. The filter screen is provided with a water inlet hole that is directly opposite to and communicates with the filter cup. When the cleaning device is cleaning, the water flow generated can enter the water collection chamber after passing through the filtration of the filter screen, while the large particle impurities in the water flow can directly enter the filter cup through the water inlet hole.

A plurality of spoiler vanes are arranged around the outer periphery of the bottom of the centrifugal filter screen. The water flow flows into the centrifugal chamber from the area near the bottom of the centrifugal chamber and impacts the spoiler vanes. After being impacted by the water flow, the spoiler vanes drive the centrifugal filter screen to rotate. After the centrifugal filter screen rotates, it can clean the impurities attached to the upstream side surface of the centrifugal filter screen through centrifugal force. At the same time, the spoiler vanes can also disturb the water flow in the centrifugal chamber to prevent impurities from accumulating in the centrifugal chamber. A communication port higher than the bottom of the centrifugal chamber is arranged on the side wall of the centrifugal chamber. The impurities located in the centrifugal chamber can enter the slag collection chamber through the communication port for centralized treatment of the impurities. The water flow that has passed through the filtration of the centrifugal filter screen can flow into the circulation pump for secondary use, improving the utilization rate of the water resources of the cleaning device. The outlet of the circulation pump is connected to a backwashing member located inside the centrifugal filter screen. Thus, a part of the water flow flowing out of the circulation pump can backwash and clean the centrifugal filter screen, further cleaning the centrifugal filter screen and improving the filtering effect of the centrifugal filter screen.

[0040] The embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0041] Cleaning devices usually are provided with a filtering device for cleaning and filtering water flow so as to reuse the water flow. However, after long - term use, impurities (such as food residues, sediment or other foreign matters) are likely to adhere to the surface of the filtering device or block the flow channel of the water flow. Therefore, the cleaning device needs to be provided with a turbulence - generating structure in the flow channel to change the flow form of the water flow so as to clean the filtering device or avoid blockage of the flow channel.

[0042] The following refers to Figures 1-6 Describe a filtering device according to an embodiment of the present utility model.

[0043] The filtering device 1 according to the present utility model includes a base 11, a centrifugal filter screen 15, and a flow disturbing member 17. A centrifugal chamber 13 and a slag collection chamber 14 are formed inside the base 11. The centrifugal chamber 13 is adapted to communicate with a cleaning device, and a communication port 131 communicating with the slag collection chamber 14 is formed on the wall surface of the centrifugal chamber 13; the centrifugal filter screen 15 is received in the centrifugal chamber 13 and is adapted to filter impurities flowing through the centrifugal filter screen 15, and the upstream side of the centrifugal filter screen 15 is connected to the communication port 131; the flow disturbing part is arranged on the upstream side of the centrifugal filter screen 15 to stir the residual impurities on the upstream side to enter the slag collection chamber 14 through the communication port 131.

[0044] The filtering device 1 according to the present utility model is provided with a base 11. A centrifugal chamber 13 and a slag collection chamber 14 are formed inside the base 11. A centrifugal filter screen 15 for filtering water flow is arranged in the centrifugal chamber 13, and the slag collection chamber 14 can be used to collect foreign residue filtered out by the filtering device 1. A communication port 131 connecting the centrifugal chamber 13 and the slag collection chamber 14 is arranged on the side wall of the centrifugal chamber 13, and the impurities entering the centrifugal chamber 13 can enter the slag collection chamber 14 through the communication port 131 driven by the water flow. Specifically, the water flow of the cleaning device can enter the centrifugal chamber 13 through the diversion of the flow channel. The water flow passes through the centrifugal filter screen 15 and can enter the circulating water path of the cleaning device for secondary use, and the impurities in the water flow stay on the upstream side of the centrifugal filter screen 15 or remain in the centrifugal chamber 13. At this time, the filtering device 1 is provided with a flow disturbing member 17 on the upstream side of the centrifugal filter screen 15. The flow disturbing member 17 can stir the flow of the water in the centrifugal chamber 13, effectively avoiding the accumulation of impurities in the centrifugal chamber 13. At the same time, the stirred water flow can wash the surface on the upstream side of the centrifugal filter screen 15 to avoid the blockage of the centrifugal filter screen 15 by impurities, thereby improving the filtering effect of the filtering device 1. The water flow stirred by the flow disturbing member 17 can better drive the impurities to enter and exit the slag collection chamber 14 through the communication port 131 for centralized treatment of the impurities.

[0045] It should be noted that the communication port 131 is higher than the bottom of the centrifugal chamber 13, and the water flow enters the centrifugal chamber 13 from the bottom or a position close to the bottom of the centrifugal chamber 13, which can prevent the impurities in the slag collection chamber 14 from being directly impacted by the water flow and returning to the centrifugal chamber 13.

[0046] The setting of the flow disturbing member 17 not only helps the automatic slag discharge of the filtering device 1, effectively avoiding the blockage and accumulation of impurities in the centrifugal chamber 13, but also can effectively clean the impurities adhered to the surface on the upstream side of the filter screen, avoid the blockage of the filter screen, and maintain the filtering efficiency of the filter screen. At the same time, by stirring the flow of the water on the upstream side by the flow disturbing member 17, the filtering effect of the impurities can be further improved.

[0047] According to an embodiment of the present utility model, the spoiler member 17 protrudes from the upstream side of the centrifugal filter screen 15; and / or the spoiler member 17 protrudes from the wall surface of the centrifugal chamber 13; and / or the spoiler member 17 is movably disposed between the upstream side of the centrifugal filter screen 15 and the wall surface of the centrifugal chamber 13.

[0048] The spoiler member 17 is a key structure for preventing the filter device 1 from being blocked. Therefore, the position of the spoiler member 17 will affect the filtration of the water flow of the cleaning device by the filter device 1 and the spoiler effect of the spoiler member 17. During the assembly of the filter device 1, it is only necessary to ensure that the spoiler member 17 is located between the surface on the upstream side of the centrifugal filter screen 15 and the centrifugal side wall. Such a position can ensure that the spoiler member 17 can stir the water flow on the upstream side of the centrifugal filter screen 15.

[0049] When the spoiler member 17 protrudes from the surface on the upstream side of the centrifugal filter screen 15, the spoiler member 17 can more directly stir the fluid and residual impurities on the upstream side, making it easier for them to enter the slag collection chamber 14 through the communication port 131. The protruding design increases the contact area between the spoiler member 17 and the fluid, thereby improving the stirring effect.

[0050] When the spoiler member 17 protrudes from the wall surface of the centrifugal chamber 13, the spoiler member 17 can not only stir the fluid and impurities on the upstream side, but also may have a certain influence on the fluid flow in the centrifugal chamber 13, guiding more impurities to move towards the communication port 131, thereby improving the slag discharge efficiency.

[0051] When the spoiler member 17 is located between the upstream side of the centrifugal filter screen 15 and the wall surface of the centrifugal chamber 13, the spoiler member 17 can be reasonably planned according to the actual size of the filter device 1, with higher flexibility. For example, the filter device 1 can adjust the position, angle or movement mode of the spoiler member 17 and optimize the spoiler member 17 according to different cleaning requirements and usage scenarios to achieve the best stirring and slag discharge effects.

[0052] According to an embodiment of the present utility model, the centrifugal filter screen 15 is configured in a cylindrical shape, and the flow disturbing member 17 is disposed on the outer peripheral wall of the centrifugal filter screen 15. The structure of the centrifugal filter screen 15 affects the filtering effect of the filtering device 1. Specifically, the centrifugal filter screen 15 is configured in a cylindrical shape. The outer surface of the cylinder can be understood as the upstream side of the centrifugal filter screen 15, and the inside of the cylinder can be understood as the downstream side of the centrifugal filter screen 15. The water flow of the cleaning device enters the centrifugal chamber 13 and can be filtered through the cylindrical centrifugal filter screen 15. The impurities in the water flow are retained in the centrifugal chamber 13, and the filtered water flow enters the inside of the centrifugal filter screen 15 and can enter the circulating water path or other structures. The design of the cylindrical centrifugal filter screen 15 can increase the contact area between the centrifugal filter screen 15 and the water flow in a limited space, improving the filtering effect. In addition, the cylindrical centrifugal filter screen 15 can self-clean the impurities attached to the outer surface of the filter screen through the centrifugal force generated by rotation, further preventing the centrifugal filter screen 15 from being blocked.

[0053] According to an embodiment of the present utility model, the flow disturbing member 17 is configured as a plurality of flow disturbing vanes disposed on the outer periphery of the centrifugal filter screen 15, and each flow disturbing vane is inclined in the same direction relative to the axis of the centrifugal filter screen 15. The presence of the plurality of flow disturbing vanes increases the area of contact with the fluid, making the stirring effect more significant. When the water flow passes through the centrifugal filter screen 15, the flow disturbing vanes can more effectively disturb the water flow, prompting the residual impurities and particulate matters to be more easily carried by the water flow from the upstream side to the communication port 131 and then enter the slag collection chamber 14.

[0054] The flow disturbing vanes are inclined in the same direction relative to the axis of the centrifugal filter screen 15. The inclined flow disturbing vanes help to guide the fluid to flow in a certain direction. The inclined flow disturbing vanes can generate a certain thrust or guiding force, enabling the impurities and particulate matters in the fluid to more easily enter the slag collection chamber 14 along a predetermined path under the combined action of the centrifugal force and the flow disturbing vanes, thereby improving the slag discharge efficiency. At the same time, the thrust generated by the water flow on the flow disturbing vanes can push the cylindrical centrifugal filter screen 15 to rotate, increasing the rotation speed of the centrifugal filter screen 15, further enhancing the ability of the centrifugal filter screen 15 to self-clean the impurities on the surface of the filter screen through centrifugal force, and thus preventing the centrifugal filter screen 15 from being blocked and improving the filtering effect of the filtering device 1.

[0055] According to an embodiment of the present utility model, the height of each spoiler in the axial direction is L1, and the height of the centrifugal filter screen 15 in the axial direction is L2, and they satisfy: 0.1 ≤ L1 / L2 ≤ 0.25. Since the spoiler is arranged on the centrifugal filter screen 15, it is necessary to define the dimensional relationship between the spoiler and the centrifugal filter screen 15. Specifically, if the height of the spoiler in the axial direction is L1 and the height of the centrifugal filter screen 15 in the axial direction is L2, then 0.1 ≤ L1 / L2 ≤ 0.25. When L1 / L2 ≤ 0.1, that is, when the height of the spoiler relative to the centrifugal filter screen 15 is too low, the flow disturbing effect of the spoiler is weak, which easily causes blockage in the centrifugal chamber 13; when L1 / L2 ≥ 0.25, that is, when the height of the spoiler relative to the centrifugal filter screen 15 is too high, the spoiler will block the centrifugal filter screen 15 and affect the filtering effect of the centrifugal filter screen 15. Therefore, setting the ratio of L1 / L2 within the range of 0.1 to 0.25 can take into account the filtering performance of the centrifugal filter screen 15 while improving the flow disturbing ability of the spoiler.

[0056] According to an embodiment of the present utility model, the centrifugal filter screen 15 is configured as a cylindrical shape open towards the bottom, and the spoiler is arranged on the outer periphery of the centrifugal filter screen 15 adjacent to the open side. The centrifugal filter screen 15 is provided with an open port at the bottom, and the water flow filtered by the centrifugal filter screen 15 can enter the inside of the centrifugal filter screen 15 and flow into the circulating water path or other structures of the cleaning device through the open port at the bottom of the centrifugal filter screen 15. The spoiler is arranged on the outer periphery of the centrifugal filter screen 15 adjacent to the open side of the centrifugal filter screen 15, which can also be simply understood as: the spoiler is located on the outer periphery of the centrifugal filter screen 15 close to the bottom. Such a layout design can make the spoiler close to the bottom of the centrifugal chamber 13. Since the water flow enters the centrifugal chamber 13 from the bottom of the centrifugal chamber 13 and flows towards the communication port 131 higher than the bottom of the centrifugal chamber 13, the water flow speed at the bottom of the centrifugal chamber 13 is fast. The spoiler located at the bottom of the centrifugal chamber 13 can improve the flow disturbing effect and can also increase the thrust generated by the water flow on the spoiler.

[0057] According to an embodiment of the present utility model, the filtering device 1 further includes: a driving device, which is connected to the flow disturbing component 17 and is adapted to drive the flow disturbing component 17 to disturb the impurities on the upstream side of the centrifugal filter screen 15. Different from the above embodiment, the filtering device 1 can also be provided with a driving device for driving the flow disturbing component 17 to work. When the water flow of the cleaning device enters the centrifugal chamber 13, the driving device can drive the flow disturbing component 17 to disturb the impurities on the upstream side of the centrifugal filter screen 15, so as to prevent the impurities from accumulating in the filter screen and the centrifugal chamber 13. It should be noted that the flow disturbing component 17 here is different from the spoiler in the above embodiment, and can also be other flow disturbing structures convexly arranged on the side wall of the centrifugal chamber 13 or between the side wall of the centrifugal chamber 13 and the centrifugal filter screen 15.

[0058] According to an embodiment of the present utility model, a water collecting cavity 12 communicating with the centrifugal cavity 13 is formed on the base 11. The centrifugal cavity 13 is communicated with the cleaning device through the water collecting cavity 12, and the water collecting cavity 12 is open towards the top. The filtering device 1 further provides a water collecting cavity 12 communicating with the centrifugal cavity 13 on the base 11. The water collecting cavity 12 is open towards the top, and the open mouth of the water collecting cavity 12 is communicated with the cleaning device. The water flow of the cleaning device can converge into the water collecting cavity 12 through the open mouth of the water collecting cavity 12. The water collecting cavity 12 can converge the water flowing out of the cleaning device and then introduce it into the centrifugal cavity 13, avoiding the residue of water flow in the cleaning device or other structures of the filtering device 1.

[0059] According to an embodiment of the present utility model, the filtering device 1 further includes: a filtering cup 121, and the filtering cup 121 is received in the water collecting cavity 12. A filtering cup 121 is arranged in the centrifugal cavity 13. The filtering cup 121 is communicated with the water flow of the cleaning device. The filtering cup 121 can filter large particle impurities in the water flow flowing out of the cleaning device, avoiding the large particle impurities from entering the centrifugal cavity 13 and blocking the centrifugal cavity 13.

[0060] According to an embodiment of the present utility model, the filtering device 1 further includes: a filter screen 18, and the filter screen 18 is arranged on the top of the base 11. The filter screen 18 is formed with a water dropping hole 181, and the water dropping hole 181 faces the open side of the water collecting cavity 12. The filtering device 1 further provides a filter screen 18. The filter screen 18 is located on the top of the base 11, which can also be understood that the filter screen 18 is located between the base 11 and the water outlet of the cleaning device. The water flow flowing out of the water outlet of the cleaning device enters the filter screen 18 for the first filtration. The filtered water can flow into the water collecting cavity 12, and after the confluence of the water collecting cavity 12, it flows into the centrifugal cavity 13 for secondary filtration. The setting of the filter screen 18 further improves the filtering effect of the filtering device 1. In addition, a water dropping hole 181 facing the filtering cup 121 is also formed in the filter screen 18. The large particle impurities carried in the water flow flowing out of the cleaning device can enter the filtering cup 121 through the water dropping hole 181. After the filtering cup 121 collects the large particle impurities, they can be uniformly processed, avoiding the large particle impurities from blocking other structures and some flow channels in the filtering device 1.

[0061] According to an embodiment of the present utility model, the filtering device 1 further includes: a circulation pump 161 and a backwashing member 162. The inlet end of the circulation pump 161 is communicated with the centrifugal cavity 13 and is located on the downstream side of the centrifugal filter screen 15; the backwashing member 162 is arranged in the centrifugal cavity 13 and is located on the downstream side of the centrifugal filter screen 15. The backwashing member 162 is connected to the outlet end of the circulation pump 161, and spray holes facing the centrifugal filter screen 15 are formed on the backwashing member 162.

[0062] A circulating water path can be arranged inside the filtering device 1. The water flow filtered by the centrifugal filter screen 15 can flow through the circulating water path of the filtering device 1 for secondary utilization. Specifically, a circulating pump 161 is also arranged in the filtering device 1. The inlet of the circulating pump 161 is communicated with the downstream side inside the centrifugal filter screen 15 (i.e., the internal space of the cylindrical centrifugal filter screen 15). That is, the water flow filtered by the centrifugal filter screen 15 can enter the circulating pump 161. The outlet of the circulating pump 161 is communicated with a backwashing member 162 located on the downstream side of the centrifugal filter screen 15. It can also be simply understood that the circulating pump 161 is a part of the circulating water path, and the backwashing member 162 is a branch of the circulating water path. That is, the water flowing out of the circulating pump 161 can also flow back to the cleaning device for secondary use. A nozzle facing the centrifugal filter screen 15 is arranged on the backwashing member 162. The water flow entering the backwashing member 162 can be sprayed from the nozzle towards the centrifugal filter screen 15 to clean the centrifugal filter screen 15. The arrangement of the backwashing member 162 can further improve the cleaning effect of the filtering device 1 on the centrifugal filter screen 15 and ensure that the centrifugal filter screen 15 will not be blocked.

[0063] According to an embodiment of the present invention, the backwashing members 162 are configured to be multiple and arranged at intervals on the inner circumference of the centrifugal filter screen 15. The multiple backwashing members 162 can be arranged at different positions. When the centrifugal filter screen 15 rotates, the multiple backwashing members 162 wash the centrifugal filter screen 15 simultaneously, which can improve the cleaning effect of the backwashing members 162 on the centrifugal filter screen 15.

[0064] According to an embodiment of the present invention, the spray holes of at least two backwashing members 162 are staggered in the height direction. When arranging the backwashing members 162, it should be noted that at least two backwashing members 162 are staggered in the height direction. When the centrifugal filter screen 15 rotates, the staggered backwashing members 162 can ensure that every area of the centrifugal filter screen 15 can be washed, thereby ensuring the cleaning effect of the backwashing members 162 on the centrifugal filter screen 15.

[0065] The cleaning device according to the present invention will be briefly described below.

[0066] The cleaning device according to the present invention includes the filtering device 1 in the above embodiment. Since the cleaning device according to the present invention is provided with the filtering device 1 in the above embodiment, therefore, the water flow generated after the cleaning device performs the cleaning work can be filtered by the filtering device 1, and the filtered water flow can be used for secondary use, improving the water resource utilization efficiency of the cleaning device and realizing environmental protection and cost reduction and efficiency increase.

[0067] In some embodiments, the cleaning device can be a dishwasher.

[0068] In summary, the cleaning device is provided with a filtering device 1. The filtering device 1 is provided with a base 11 located at the bottom of the cleaning device and a filter net 18 located at the top of the base 11. An centrifugal chamber 13 and a water collecting chamber 12 opening towards the top are arranged on the base 11. A filter cup 121 is arranged in the water collecting chamber 12. A water falling hole 181 which is opposite to and communicated with the filter cup 121 is arranged on the filter net 18. When the cleaning device is cleaning, the water flow generated can enter the water collecting chamber 12 after being filtered by the filter net 18, and the large particle impurities in the water flow can directly enter the filter cup 121 through the water falling hole 181. The filter cup 121 can collect the large particle impurities, prevent the large particle impurities from blocking the filtering device 1, and is convenient for unified treatment. The water flow entering the water collecting chamber 12 can flow into the centrifugal chamber 13 after converging. An centrifugal filter net 15 is arranged in the centrifugal chamber 13. The centrifugal filter net 15 is configured in a cylindrical shape. The water flow entering the centrifugal chamber 13 is located on the upstream side of the centrifugal filter net 15, that is, the outer surface of the centrifugal filter net 15. After the water flow passes through the centrifugal filter net 15, it enters the downstream side of the centrifugal filter net 15 (that is, the internal space of the centrifugal filter net 15). A plurality of flow disturbing pieces surrounding the outer periphery of the bottom of the centrifugal filter net 15 are arranged on the centrifugal filter net 15. The water flow flows into the centrifugal chamber 13 from the area near the bottom of the centrifugal chamber 13 and impacts the flow disturbing pieces. After being impacted by the water flow, the flow disturbing pieces drive the centrifugal filter net 15 to rotate. After the centrifugal filter net 15 rotates, it can clean the impurities attached to the upstream side surface of the centrifugal filter net 15 by centrifugal force. At the same time, the flow disturbing pieces can also disturb the water flow in the centrifugal chamber 13 to prevent the impurities from accumulating in the centrifugal chamber 13. A communication port 131 higher than the bottom of the centrifugal chamber 13 is arranged on the side wall of the centrifugal chamber 13. The impurities located in the centrifugal chamber 13 can enter the slag collecting chamber 14 through the communication port 131 for convenient centralized treatment of the impurities. The water flow filtered by the centrifugal filter net 15 can flow into the circulation pump 161 for secondary use, improving the utilization rate of the water resources of the cleaning device. The outlet of the circulation pump 161 is communicated with a backwashing member 162 located inside the centrifugal filter net 15. Thus, a part of the water flow flowing out of the circulation pump 161 can backwash and clean the centrifugal filter net 15 to further clean the centrifugal filter net 15 and improve the filtering effect of the centrifugal filter net 15.
