Description

Technical Field

[0001] Embodiments of the present invention relate to the technical field of separators, and more specifically, to a separator and a household appliance. Background Art

[0002] A cyclone separator is a device used to separate solid particles in a fluid. In related technologies, a filter screen is provided in the cyclone separator to filter the solid particles in the fluid. However, during the operation of the cyclone separator, a small amount of solid particles will adhere to the filter screen. If it runs for a long time and multiple times, more solid particles are likely to accumulate on the filter screen, and users need to clean the filter screen regularly. Summary of the Invention

[0003] Embodiments of the present invention aim to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of the embodiments of the present invention provides a separator.

[0005] A second aspect of the embodiments of the present invention provides a household appliance.

[0006] In view of this, according to the first aspect of the embodiments of the present invention, there is provided a separator, which includes: a housing provided with a chamber; a first filter member disposed in the chamber, the first filter member enclosing a first passage, and at least a part of the outer wall of the first filter member and the inner wall of the housing enclosing a second passage, the second passage communicating with the first passage; a feed port disposed on the housing, the feed port communicating with the second passage; a disturbance assembly disposed in the housing, a part of the disturbance assembly being located in the first passage; and a driving device connected to the disturbance assembly, the driving device being capable of driving the disturbance assembly to move.

[0007] The separator provided by the embodiments of the present invention includes a housing, a first filter member, a feed port, a disturbance assembly, and a driving device. Specifically, when the separator operates, the fluid mixed with solid particles and flowing at a high speed enters the separator from the feed port, and then flows circumferentially along the inner wall of the second passage to form a swirl. After the swirl separation, the relatively lighter liquid and / or gas and the relatively heavier solid particles are separated under the action of centrifugal force.

[0008] The first filter member is disposed in the chamber and encloses a first passage. At least a part of the outer wall of the first filter member and the inner wall of the housing enclose a second passage, and the second passage communicates with the first passage, so that the fluid entering the second passage from the feed port can enter the first passage after being filtered by the first filter member. That is to say, the first filter member can filter the solid particles in the fluid and allow the filtered liquid and / or gas to be discharged from the separator through the first passage, avoiding the mixing of solid particles in the liquid and / or gas, and effectively realizing the separation of gas, liquid, and solid.

[0009] Meanwhile, when the separator is operating, the fluid mixed with solid particles and flowing at a high speed enters the separator from the feed port, and then flows circumferentially along the inner wall of the second channel to form a swirl. When the swirl passes through the first filter element and enters the first channel, the first filter element can exert a certain resistance on the flow of the swirl, thereby weakening the swirl intensity of the fluid entering the first channel and further reducing the flow resistance of the separator.

[0010] Furthermore, the perturbation assembly is arranged in the housing, and a part of the perturbation assembly is located in the first channel. The driving device can drive the perturbation assembly to move. It can be understood that the movement of the perturbation assembly can perturb the fluid in the first channel, causing the fluid to be thrown towards the surroundings and hit the first filter element, thereby having a reverse flushing effect on the first filter element and realizing the cleaning of the first filter element.

[0011] Specifically, during the operation of the separator, pollutants such as solid particles are likely to deposit on the side of the first filter element facing away from the first channel, that is, pollutants are likely to deposit on the first filter element outside the first channel. After the separator is used for a long time, the first filter element is likely to be blocked, and the user needs to regularly disassemble and clean the first filter element. By arranging the perturbation assembly in the housing and a part of the perturbation assembly being located in the first channel, when the first filter element needs to be cleaned, the separator is controlled to stop operating, and the driving device is started. Under the drive of the driving device, the perturbation assembly can perturb the fluid, thereby realizing the automatic cleaning of the first filter element without the user manually disassembling the first filter element for regular cleaning, improving the user experience.

[0012] In addition, the separator provided by the above technical solution of the present invention further has the following additional technical features:

Detailed implementation manners

[0044] In order to more clearly understand the above objects, features and advantages of the present invention, the present invention will be further described in detail below with reference to the drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0045] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0046] Next, refer to Figures 1 to 8 to describe the separator 100 and the household appliance provided according to some embodiments of the present invention.

[0047] Embodiment 1:

[0048] As Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown in the figure, an embodiment of the first aspect of the present invention provides a separator 100, which includes: a housing 110 provided with a chamber 112; a first filter element 120 disposed in the chamber 112, the first filter element 120 enclosing a first channel, and at least a part of the outer wall of the first filter element 120 and the inner wall of the housing 110 enclosing a second channel 130, the second channel 130 communicating with the first channel; a feed port provided on the housing 110, the feed port communicating with the second channel 130; a disturbance assembly 150 disposed in the housing 110, a part of the disturbance assembly 150 being located in the first channel; and a driving device 160 connected to the disturbance assembly 150, the driving device 160 being capable of driving the disturbance assembly 150 to move.

[0049] The separator 100 provided by the embodiment of the present invention includes a housing 110, a first filter element 120, a feed port, a disturbance assembly 150, and a driving device 160. Specifically, when the separator 100 operates, a fluid mixed with solid particles and flowing at a high speed enters the separator 100 from the feed port, and then flows circumferentially along the inner wall of the second channel 130 to form a swirl. After the swirl separation, the relatively lighter liquid and / or gas and the relatively heavier solid particles are separated under the action of centrifugal force. In practical applications, the housing 110 is cylindrical, that is to say, the second channel 130 is an annular channel, and a diversion pipe 170 is provided at the position of the feed port. The diversion pipe 170 is connected to the side wall of the housing 110, so that the fluid enters the chamber 112 at the tangential position of the annular channel, thereby enabling the fluid entering the chamber to flow circumferentially along the inner wall of the second channel 130 to form a swirl and ensuring the separation effect.

[0050] The first filter element 120 is disposed in the chamber 112, and the first filter element 120 encloses a first channel. At least a part of the outer wall of the first filter element 120 and the inner wall of the housing 110 enclose a second channel 130, and the second channel 130 communicates with the first channel, so that the fluid entering the second channel 130 from the feed port can enter the first channel after being filtered by the first filter element 120. That is to say, the first filter element 120 can filter the solid particles in the fluid, allowing the liquid and / or gas to be discharged from the separator 100 through the first channel, avoiding the mixing of solid particles in the liquid and / or gas, and effectively realizing the separation of gas, liquid, and solid.

[0051] At the same time, since when the separator 100 operates, a fluid mixed with solid particles and flowing at a high speed enters the separator 100 from the feed port and then flows circumferentially along the inner wall of the second channel 130 to form a swirl, when the swirl flows through the first filter element 120 for filtration and enters the first channel, the first filter element 120 can exert a certain resistance on the flow of the swirl, thereby weakening the swirl intensity of the fluid entering the first channel and further reducing the flow resistance of the separator 100.

[0052] Further, the perturbation component 150 is disposed within the housing 110, and a part of the perturbation component 150 is located within the first channel. The driving device 160 can drive the perturbation component 150 to move. It can be understood that the movement of the perturbation component 150 can perturb the fluid within the first channel, causing the fluid to be flung around and strike the first filter element 120, thereby having a reverse flushing effect on the first filter element 120 and achieving the cleaning of the first filter element 120.

[0053] Specifically, during the operation of the separator 100, pollutants such as solid particles are likely to deposit on the side of the first filter element 120 facing away from the first channel, that is, pollutants are likely to deposit on the first filter element 120 outside the first channel. After long-term use of the separator 100, the first filter element 120 is likely to be blocked, and the user needs to regularly disassemble and clean the first filter element 120. By disposing the perturbation component 150 within the housing 110 and having a part of the perturbation component 150 located within the first channel, when the first filter element 120 needs to be cleaned, the separator 100 is controlled to stop operating, and the driving device 160 is started. Under the drive of the driving device 160, the perturbation component 150 can perturb the fluid, thereby realizing the automatic cleaning of the first filter element 120 without the user manually disassembling the first filter element 120 for regular cleaning, improving the user experience.

[0054] Wherein, the first filter element 120 includes a filtering portion, and the filtering portion includes at least one of filtering holes and filtering openings. The number of filtering portions is multiple, and the multiple filtering portions are uniformly arranged. The solid particles in the fluid flowing through the first filter element 120 can be filtered through the filtering portion. Among them, the solid particles include spherical solid particles with a density much greater than that of the liquid, and the solid particles can also be flat solid particles with a density slightly greater than that of the liquid.

[0055] Specifically, the filtering method of the dishwasher 300 is circular filtering. The water flowing out contains some pollutants and will cause secondary pollution to the tableware 380. By applying this separator 100 to the dishwasher 300, after the sewage passes through the separator 100, all pollutants are intercepted, and the water flowing out is clean water, which will not cause secondary pollution to the tableware 380, is beneficial to improving the washing effect, reducing the washing time, and saving water consumption.

[0056] In practical applications, the separator 100 is a hydrocyclone separator 100, and the fluid refers to a mixture of liquid and solid particles, or a mixture of liquid, gas and solid particles, or a mixture of gas and solid particles.

[0057] Embodiment Two:

[0058] Such as Figure 3 、 Figure 4 and Figure 7As shown, on the basis of the above embodiments, further, the disturbance component 150 includes a first impeller 151; the first impeller 151 includes a first support member 1511 and a plurality of first blades 1512. Among them, the first support member 1511 is connected to the driving device 160, and the plurality of first blades 1512 are arranged at intervals in the circumferential direction on the first support member 1511.

[0059] In this embodiment, it is defined that the disturbance component 150 includes a first impeller 151. It can be understood that the first impeller 151 is a centrifugal impeller. Driven by the driving device 160, the rotation of the first impeller 151 can disturb the fluid in the first channel. The disturbed fluid is thrown onto the inner wall of the first filter element 120 under the action of centrifugal force. The fluid hitting the inner wall of the first filter element 120 can have a reverse flushing effect on the first filter element 120, thereby flushing off pollutants such as solid particles attached to the first filter element 120 and realizing the cleaning of the first filter element 120. And compared with scraping the blades directly from the filter screen in the related art, by discharging the pollutants in the reverse direction, it is easier to clean.

[0060] Specifically, the first impeller 151 includes a first support member 1511 and a plurality of first blades 1512. The plurality of first blades 1512 are arranged at intervals in the circumferential direction of the first support member 1511 on the first support member 1511. The driving device 160 is connected to the first support member 1511. Driven by the driving device 160, the first support member 1511 can drive the plurality of first blades 1512 to rotate to disturb the flow in the first channel. The disturbed fluid is thrown onto the inner wall of the first filter element 120 under the action of centrifugal force. The fluid hitting the inner wall of the first filter element 120 can have a reverse flushing effect on the first filter element 120, thereby flushing off pollutants such as solid particles attached to the first filter element 120 and realizing the cleaning of the first filter element 120, without the user having to manually disassemble the first filter element 120 for regular cleaning, improving the user experience.

[0061] In a specific embodiment, further, the distance d1 between at least one side of the first blade 1512 close to the first filter element 120 and the inner wall of the first filter element 120 satisfies 1mm ≤ d1 ≤ 4mm.

[0062] In this embodiment, it is defined that the distance d1 between at least one side of the first blade 1512 close to the first filter element 120 and the inner wall of the first filter element 120 is greater than or equal to 1mm and less than or equal to 4mm. That is to say, the distance between at least one first blade 1512 and the inner wall of the first filter element 120 is relatively close, so that the impact force of the fluid disturbed by the first blade 1512 hitting the inner wall of the first filter element 120 is relatively large, which can improve the cleaning effect on the first filter element 120.

[0063] It can be understood that the distance d1 should not be too small. If the distance between the first blade 1512 and the first filter element 120 is too small, it is likely to affect the flow of the liquid flowing from the first channel to the outlet portion 180, reducing the separation efficiency. Moreover, the distance d1 should not be too large. If the distance between the first blade 1512 and the first filter element 120 is too large, the impact force of the disturbed fluid hitting the inner wall of the first filter element 120 is small, which is not conducive to the cleaning effect of the first filter element 120. By limiting d1 to be between 1 mm and 4 mm, it is possible to improve the effective cleaning of the first filter element 120 while not affecting the flow of the fluid between the first channel and the outlet portion 180, ensuring the separation efficiency.

[0064] It should be noted that in practical applications, by limiting the distance between the side of each first blade 1512 close to the first filter element 120 and the inner wall of the first filter element 120 to 2 mm, it is possible to improve the effective cleaning of the first filter element 120 while not affecting the flow of the fluid between the first channel and the outlet portion 180, ensuring the separation efficiency.

[0065] On the basis of the above embodiments, further, the first end of each first blade 1512 is connected to the first support member 1511, and the second end of each first blade 1512 extends along the axial direction of the first impeller 151.

[0066] In this embodiment, one end of each first blade 1512 is connected to the first support member 1511, and the other end of each first blade 1512 extends along the axial direction of the first impeller 151. It can be understood that the first channel extends along the axial direction of the first impeller 151. That is to say, the first filter element 120 has a certain dimension in the axial direction of the first impeller 151. By axially extending the free end of each first blade 1512, under the drive of the driving device 160, the amount of liquid and / or gas disturbed by the first blade 1512 can be increased, so that more disturbed liquid and / or gas hits the inner wall of the first filter element 120, improving the cleaning effect of the first filter element 120.

[0067] In a specific embodiment, further, along the axial direction of the first impeller 151, the dimension of the first filter element 120 is equal to the length of the first blade 1512.

[0068] In this embodiment, along the axial direction of the first impeller 151, the size of the first filter element 120 is equal to the length of the first blade 1512, that is, the length of the first filter element 120 in the axial direction of the first impeller 151 is equal to the length of the first blade 1512 extending along the axial direction of the first blade 1512, so that under the drive of the driving device 160, the liquid and / or gas disturbed by the first blade 1512 can hit various positions on the inner wall of the first filter element 120, thereby achieving comprehensive cleaning of the first filter element 120 and further improving the cleaning effect of the first filter element 120.

[0069] like Figure 4 As shown, based on the above embodiment, the disturbance assembly 150 further includes a first fixing member 152 , and the first fixing member 152 is connected to the second end of each first blade 1512 .

[0070] In this embodiment, the disturbance assembly 150 is further defined as including a first fixing member 152. Specifically, the first fixing member 152 is connected to the second end of each first blade 1512. That is, the free end of each first blade 1512 is connected via the first fixing member 152. Thus, when the first blade 1512 disturbs the fluid in the first channel under the drive of the driving device 160, the first blade 1512 can be prevented from being deformed or broken, thereby extending the service life of the first impeller 151.

[0071] It should be noted that the first fixing member 152, the plurality of first blades 1512, and the first support member 1511 are integrally formed. It will be appreciated that this integral structure exhibits excellent mechanical properties, thereby improving the connection strength between the first fixing member 152 and the first blades 1512, and between the first blades 1512 and the first support member 1511, thereby extending the service life of the agitation assembly 150. Furthermore, this integral structure facilitates processing and production, thereby reducing the production cost of the agitation assembly 150, and thereby reducing the production cost of the separator 100.

[0072] like Figure 4 and Figure 7 As shown, based on the above embodiment, the disturbance assembly 150 further includes a plurality of first through holes 153, which are circumferentially spaced apart on the first support member 1511, and the plurality of first through holes 153 are connected to the first channel.

[0073] In this embodiment, it is defined that the perturbation assembly 150 further includes a plurality of first through holes 153. Specifically, a plurality of first through holes 153 are provided on the first support member 1511, and the plurality of first through holes 153 are arranged along the circumferential direction of the first support member 1511. The plurality of first through holes 153 communicate with the first channel. By providing a plurality of first through holes 153 in the first support member 1511, the flow area of the liquid / or gas between the first channel and the outlet portion 180 can be increased, and the separation efficiency can be improved.

[0074] It should be noted that the number of the first through holes 153 can be set according to actual needs. It can be understood that the number of the first through holes 153 should not be too large, because too many first through holes 153 will reduce the structural strength of the first support member 1511, and the number of the first through holes 153 should not be too small, because too few first through holes 153 will affect the flow area between the first channel and the outlet portion 180 and reduce the separation efficiency. Therefore, the number of the first through holes 153 needs to be reasonably set to ensure the separation efficiency of the separator 100 on the basis of ensuring the structural strength of the first support member 1511.

[0075] Embodiment Three:

[0076] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 shown, on the basis of any of the above embodiments, further, the separator 100 further includes a diversion pipe 170, an outlet portion 180 and a discharging portion 190. Among them, the diversion pipe 170 is connected to the housing 110 and is located at the feed inlet. The diversion pipe 170 communicates with the second channel 130 through the feed inlet. The outlet portion 180 is connected to the housing 110, and the outlet portion 180 communicates with the first channel. The discharging portion 190 is connected to the housing 110; the housing 110 includes a housing body 111 and a partition member. Among them, the partition member is arranged inside the housing body 111, and the partition member divides the chamber 112 into a first chamber 1121 and a second chamber 1122. The first filter member 120 is located in the first chamber 1121, and the second chamber 1122 communicates with the discharging portion 190; the partition member includes a discharging channel 114, and the second channel 130 communicates with the second chamber 1122 through the discharging channel 114.

[0077] In this embodiment, it is defined that the separator 100 further includes a diversion pipe 170, an outlet part 180 and a discharging part 190. Specifically, the diversion pipe 170 is connected to the housing 110 and is located at the feed inlet, and the diversion pipe 170 communicates with the second channel 130. The outlet part 180 communicates with the first channel. The partition divides the chamber 112 into a first chamber 1121 and a second chamber 1122. The first filter element 120 is located in the first chamber 1121. That is to say, the first channel formed by enclosing the first filter element 120 is located in the first chamber 1121. The outer wall of the first filter element 120 and the chamber wall of the first chamber 1121 enclose to form the second channel 130.

[0078] The partition includes a discharging channel 114. The second channel 130 communicates with the second chamber 1122 through the discharging channel 114, and the discharging part 190 communicates with the second chamber 1122. Specifically, before the separator 100 operates, the discharging part 190 is closed. Then, after the fluid mixed with solid particles and flowing at a high speed enters the separator 100 from the diversion pipe 170, it flows circumferentially along the inner wall of the second channel 130 to form a swirl. After the fluid is separated by the swirl, it enters the first channel after being filtered by the first filter element 120 and is discharged from the separator 100 through the outlet part 180. The solid particles intercepted by the first filter element 120 and the like enter the second chamber 1122 through the discharging channel 114 via the second channel 130. Then, by opening the discharging part 190, the separated solid particles are discharged from the separator 100 through the discharging part 190, realizing separation.

[0079] Moreover, the first filter element 120 is arranged in the first chamber 1121. The high-speed fluid entering the separator from the feed inlet will flow circumferentially along the inner wall of the second channel 130 to form a swirl. At the same time, under the action of centrifugal force, the fluid will bring the solid particles intercepted by the first filter element 120 from the second channel 130 into the second chamber 1122, so as to avoid the deposition of solid particles on the outer wall of the first filter element 120, prevent the first filter element 120 from being blocked, and improve the efficiency of gas-liquid-solid separation of the separator 100.

[0080] In addition, the outlet part 180 communicates with the first channel, and the discharging part 190 communicates with the second chamber 1122. That is to say, the outlet part 180 for discharging liquid and / or gas and the discharging part 190 for discharging solid particles communicate with different chambers respectively, so as to effectively prevent the solid particles intercepted by the first filter element 120 from flowing out of the separator 100 through the outlet part 180 and improve the separation effect of the separator 100.

[0081] In a specific application, the diversion pipe 170 includes an inlet pipe body, the outlet part 180 includes an outlet pipe body, a part of the outlet pipe body extends outside the housing 110, another part of the outlet pipe body extends into the first channel, and the discharging part 190 includes a discharging pipe body. The structural setting of the pipe body has a diversion effect. When the fluid flows through the pipe body, the turning of the fluid is reduced, and further the flow loss of the fluid can be reduced, so that more energy is converted into dynamic pressure, which is beneficial to increasing the flow velocity. In addition, the pipe body has a flow concentration effect, which can reduce the occurrence frequency of phenomena such as fluid flow separation, flow detachment, and vortex, and further is beneficial to reducing noise and improving the use performance of the product.

[0082] On the basis of the above embodiment, further, the first channel extends along the direction of the outlet part 180 towards the partition member.

[0083] In this embodiment, the first channel extends along the direction of the outlet part 180 towards the partition member. That is to say, the extension direction of the first channel is the same as that of the inner wall of the housing 110. Since the inner wall of the housing 110 and the outer wall of the first filter element 120 form the second channel 130, that is, the extension directions of the first channel and the second channel 130 are the same, so that the fluid flowing from the diversion pipe 170 into the second channel 130 and entering the first channel after being filtered by the first filter element 120 is filtered, ensuring that the liquid and / or gas separated by the outlet part 180 does not contain solid particles mixed therein, and improving the separation effect of the separator 100.

[0084] Embodiment Four:

[0085] As Figure 3 shown, on the basis of the above embodiment, further, the housing 110 further includes a return hole 200. The return hole 200 is arranged on the partition member, and the return hole 200 is respectively communicated with the first channel and the second chamber 1122.

[0086] In this embodiment, it is defined that the housing 110 further includes a return hole 200. Specifically, the return hole 200 is arranged on the partition member, and the return hole 200 is respectively communicated with the second chamber 1122 and the first channel. By providing the return hole 200 on the partition member, more fluid can be guided into the return hole 200 in the first chamber 1121, so that more fluid can flow into the diversion pipe 170, and the separation efficiency of the separator 100 is improved. In addition, when the fluid flows in the second channel 130 to supplement the return hole 200, the solid particles thrown to the wall of the first chamber 1121 can be carried into the second chamber 1122, so that the amount of solid particles separated into the second chamber 1122 per unit time can be increased, effectively alleviating the blockage of the first filter element 120.

[0087] Specifically, relying solely on centrifugal force, the amount of solid particles separated into the second chamber 1122 per unit time is fixed. If the amount of solid particles in the fluid is large, solid particles (such as contaminants) that are not separated in time may adhere to the first filter element 120, causing clogging of the first filter element 120. By providing a reflux hole 200 on the separator, each communicating with the first channel and the second chamber 1122, it can be understood that the area near the center of the separator 100 is a low-pressure zone. The reflux hole 200 is provided on the separator, i.e., the reflux hole 200 is located near this low-pressure zone. Consequently, within the separator 100, in addition to the flow from the flow conduit 170 through the second channel 130 and the first channel to the outlet 180, flow also occurs from the second chamber 1122 through the reflux hole 200 and the first channel to the outlet 180. In other words, more fluid is directed within the first chamber 1121 to replenish the reflux hole 200, allowing more fluid to flow into the flow conduit 170, thereby improving the separation efficiency of the separator 100. Moreover, when the fluid flows in the second channel 130 to replenish the reflux hole 200, it can carry the solid particles thrown toward the cavity wall of the first cavity 1121 into the second cavity 1122, thereby increasing the amount of solid particles separated into the second cavity 1122 per unit time, effectively alleviating the blockage of the first filter element 120.

[0088] like Figure 3 and Figure 4 As shown, on the basis of the above embodiment, the separator 100 further includes a second filter element 210, the second filter element 210 is located in the second cavity 1122, and the two ends of the second filter element 210 are clamped between the partition and the inner wall of the shell 110. The second filter element 210 encloses a third channel, and the third channel is respectively connected to the reflux hole 200 and the second cavity 1122.

[0089] In this embodiment, the separator 100 is further defined as comprising a second filter element 210. Specifically, the second filter element 210 is positioned within the second cavity 1122, with both ends of the second filter element 210 sandwiched between the partition and the inner wall of the housing 110. In other words, one end of the second filter element 210 is connected to the partition, and the other end of the second filter element 210 is connected to the inner wall of the housing 110 facing away from the reflux hole 200. The second filter element 210 encloses a third channel, which is in communication with the reflux hole 200 and the second cavity 1122, respectively. By positioning the second filter element 210 within the second cavity 1122, fluid flowing from the second cavity 1122 to the reflux hole 200 is filtered by the second filter element 210. Consequently, when the fluid flows through the reflux hole 200 and the first channel out of the outlet 180, solid particles are intercepted by the second filter element 210 and collected in the second cavity 1122, thereby improving the separation efficiency of the separator 100.

[0090] Specifically, due to the provision of the reflux holes 200 in the separator, the flow guide pipe 170 can allow more fluid to flow in per unit time, increasing the disturbance of the fluid in the second chamber 1122, preventing solid particles in the second chamber 1122 from depositing, and causing some solid particles to pass through the reflux holes 200, flow through the first channel and the outlet part 180, and flow out of the separator 100, reducing the filtration efficiency of the separator 100. By providing the second filter member 210 in the second chamber 1122, when the fluid refluxes from the second chamber 1122 to the reflux holes 200, it can be filtered by the second filter member 210, preventing the fluid mixed with solid particles from flowing out through the reflux holes 200 and the outlet part 180, and improving the separation efficiency of the separator 100.

[0091] In a specific application, the second filter member 210 includes a filtering part, the filtering part includes at least one of filtering holes and filtering ports, the number of the filtering parts is multiple, and the multiple filtering parts are uniformly arranged, and the solid particles in the fluid flowing through the second filter member 210 can be filtered by the filtering part.

[0092] It should be noted that at least one of the first filter member 120 and the second filter member 210 includes a filter net. The first filter member 120 includes a filter net, and the filter net encloses the first channel, and the cross-section of the first channel is circular, rectangular or polygonal. Or the second filter member 210 includes a filter net, and the filter net encloses the third channel, and the cross-section of the third channel is circular, rectangular or polygonal. Or both the first filter member 120 and the second filter member 210 include filter nets, and the filter nets enclose the first channel and the third channel, the cross-section of the first channel is circular, rectangular or polygonal, and the cross-section of the third channel is circular, rectangular or polygonal. Specifically, it can be set according to actual needs.

[0093] Embodiment Five:

[0094] As Figure 4 shown, on the basis of the above embodiment, further, a part of the disturbance assembly 150 is located in the third channel.

[0095] In this embodiment, it is defined that a part of the disturbance assembly 150 is located in the third channel, and the driving device 160 can drive the disturbance assembly 150 to move. It can be understood that the movement of the disturbance assembly 150 can disturb the fluid in the third channel, causing the fluid to be thrown to the surroundings and hit the inner wall of the second filter member 210, thereby having a reverse flushing effect on the second filter member 210 and realizing the cleaning of the second filter member 210.

[0096] Specifically, during the operation of the separator 100, pollutants such as solid particles are likely to deposit on the second filter element 210. After long-term use of the separator 100, the second filter element 210 is likely to be blocked, and users need to regularly disassemble and clean the second filter element 210. By arranging a disturbance component 150 inside the housing 110, and a part of the disturbance component 150 is located in the third channel. When the second filter element 210 needs to be cleaned, the separator 100 is controlled to stop operating, and the driving device 160 is started. Driven by the driving device 160, the disturbance component 150 can generate disturbance to the fluid, thereby realizing automatic cleaning of the second filter element 210, without the need for users to manually disassemble the second filter element 210 for regular cleaning, improving the user experience.

[0097] Embodiment Six:

[0098] As Figure 4 and Figure 6 shown, on the basis of the above embodiment, further, the disturbance component 150 includes a second impeller 154; the second impeller 154 includes a second support member 1541 and a plurality of second blades 1542. Among them, the second support member 1541 is connected to the driving device 160, and the plurality of second blades 1542 are circumferentially spaced on the second support member 1541.

[0099] In this embodiment, it is defined that the disturbance component 150 includes a second impeller 154. It can be understood that the second impeller 154 is a centrifugal impeller. Driven by the driving device 160, the rotation of the second impeller 154 can disturb the fluid in the third channel. The disturbed fluid is thrown onto the inner wall of the second filter element 210 under the action of centrifugal force. The fluid hitting the inner wall of the second filter element 210 can have a reverse flushing effect on the second filter element 210, thereby flushing away pollutants such as solid particles attached to the second filter element 210 and realizing the cleaning of the second filter element 210.

[0100] Specifically, the second impeller 154 includes a second support member 1541 and a plurality of second blades 1542. The plurality of second blades 1542 are circumferentially spaced on the second support member 1541 along the circumferential direction of the second support member 1541. The driving device 160 is connected to the second support member 1541. Driven by the driving device 160, the second support member 1541 can drive the plurality of second blades 1542 to rotate to disturb the flow in the third channel. The disturbed fluid is thrown onto the inner wall of the second filter element 210 under the action of centrifugal force. The fluid hitting the inner wall of the second filter element 210 can have a reverse flushing effect on the second filter element 210, thereby flushing away pollutants such as solid particles attached to the second filter element 210 and realizing the cleaning of the second filter element 210, without the need for users to manually disassemble the second filter element 210 for regular cleaning, improving the user experience.

[0101] In a specific embodiment, further, the distance d2 between at least one second blade 1542 and the inner wall of the second filter element 210 on the side close to the second filter element 210 satisfies 1 mm ≤ d2 ≤ 4 mm.

[0102] In this embodiment, the distance d2 between at least one second blade 1542 and the inner wall of the second filter element 210 on the side close to the second filter element 210 is defined to be greater than or equal to 1 mm and less than or equal to 4 mm. That is to say, the distance between at least one second blade 1542 and the inner wall of the second filter element 210 is relatively close, so that the impact force of the fluid disturbed by the second blade 1542 hitting the inner wall of the second filter element 210 is relatively large, which can improve the cleaning effect on the second filter element 210.

[0103] It can be understood that the distance d2 should not be too small. If the distance between the second blade 1542 and the second filter element 210 is too small, it is easy to affect the liquid flow from the third channel to the return hole 200 and reduce the separation efficiency. Moreover, the distance d2 should not be too large. If the distance between the second blade 1542 and the second filter element 210 is too large, the impact force of the disturbed fluid hitting the inner wall of the second filter element 210 is relatively small, which is not conducive to the cleaning effect of the second filter element 210. By defining d2 between 1 mm and 4 mm, it is possible to improve the effective cleaning of the second filter element 210 while not affecting the flow of fluid between the third channel and the return hole 200 and ensuring the separation efficiency.

[0104] It should be noted that in practical applications, when the distance between each second blade 1542 and the inner wall of the second filter element 210 on the side close to the second filter element 210 is defined to be 2 mm, it is possible to improve the effective cleaning of the second filter element 210 while not affecting the flow of fluid between the third channel and the return hole 200 and ensuring the separation efficiency.

[0105] On the basis of the above embodiment, further, the first end of each second blade 1542 is connected to the second support member 1541, and the second end of each second blade 1542 extends along the axial direction of the second impeller 154.

[0106] In this embodiment, one end of each second blade 1542 is connected to the first support 1511, and the other end of each second blade 1542 extends along the axial direction of the second impeller 154. It can be understood that the third channel extends along the axial direction of the second impeller 154. That is to say, the second filter element 210 has a certain dimension in the axial direction of the second impeller 154. The free ends of each second blade 1542 are axially extended, so that under the drive of the drive device 160, the amount of liquid and / or gas disturbed by the second blade 1542 can be increased, and more disturbed liquid and / or gas can hit the inner wall of the second filter element 210, improving the cleaning effect on the second filter element 210.

[0107] In a specific embodiment, further, along the axial direction of the second impeller 154, the dimension of the second filter element 210 is equal to the length of the second blade 1542.

[0108] In this embodiment, along the axial direction of the second impeller 154, the dimension of the second filter element 210 is equal to the length of the second blade 1542. That is to say, the length of the second filter element 210 in the axial direction of the second impeller 154 is equal to the extended length of the second blade 1542 along the axial direction of the second blade 1542. Thus, under the drive of the drive device 160, the liquid and / or gas disturbed by the second blade 1542 can hit various positions on the inner wall of the second filter element 210, realizing the comprehensive cleaning of the second filter element 210 and further improving the cleaning effect on the second filter element 210.

[0109] As Figure 4 shown, on the basis of the above embodiment, further, the disturbing assembly 150 further includes a second fixing member 155, and the second fixing member 155 is connected to the second end of each second blade 1542.

[0110] In this embodiment, it is defined that the disturbing assembly 150 further includes a second fixing member 155. Specifically, the second fixing member 155 is connected to the second end of each second blade 1542. That is to say, the free ends of each second blade 1542 are connected through the second fixing member 155. Thus, when the second blade 1542 disturbs the fluid in the third channel under the drive of the drive device 160, the second blade 1542 can be prevented from deforming or breaking, and the service life of the second impeller 154 can be prolonged.

[0111] It should be noted that the second fixing member 155, the plurality of second blades 1542 and the second support member 1541 are of an integral structure. It can be understood that the integral structure has good mechanical properties, so that the connection strength between the second fixing member 155 and the second blades 1542, and between the second blades 1542 and the second support member 1541 can be improved, and the service life of the disturbance assembly 150 can be extended. In addition, the integral structure is also convenient for processing and production, so the production cost of the disturbance assembly 150 can be reduced, and further the production cost of the separator 100 can be reduced.

[0112] As Figure 4 and Figure 6 shown, on the basis of the above embodiment, further, the disturbance assembly 150 further includes a plurality of second through holes 156. The plurality of second through holes 156 are arranged at intervals in the circumferential direction on the second support member 1541, and the plurality of second through holes 156 are respectively communicated with the return holes 200 and the third channel.

[0113] In this embodiment, it is defined that the disturbance assembly 150 further includes a plurality of second through holes 156. Specifically, a plurality of second through holes 156 are provided on the second support member 1541, and the plurality of second through holes 156 are arranged along the circumferential direction of the second support member 1541, and the plurality of second through holes 156 are communicated with the third channel. By providing a plurality of second through holes 156 on the second support member 1541, the flow area of the liquid / or gas between the third channel and the return holes 200 can be increased, and the separation efficiency can be improved.

[0114] It should be noted that the number of the second through holes 156 can be set according to actual needs. It can be understood that the number of the second through holes 156 should not be too many, otherwise the structural strength of the second support member 1541 will be reduced, and the number of the second through holes 156 should not be too few, otherwise the flow area between the third channel and the return holes 200 will be affected, and the separation efficiency will be reduced. Therefore, the number of the second through holes 156 needs to be reasonably set to ensure the separation efficiency of the separator 100 on the basis of ensuring the structural strength of the second support member 1541.

[0115] Embodiment Seven:

[0116] As Figure 5 shown, on the basis of the above embodiment, further, the separator 100 further includes a partition plate 113 and a plurality of guide vanes 220. Among them, the plurality of guide vanes 220 are arranged on the partition plate 113, the guide vanes 220 are located in the first cavity 1121, the plurality of guide vanes 220 are distributed at intervals on the periphery of the first filter element 120, and a discharge channel 114 is enclosed by any two adjacent guide vanes 220 and a part of the partition plate 113; wherein, the extending direction of the discharge channel 114 is different from the direction of the fluid in the second channel 130.

[0117] In this embodiment, it is defined that the separator 100 further includes a plurality of guide vanes 220. Specifically, a plurality of guide vanes 220 are provided on the side of the partition plate 113 facing the first chamber 1121. The plurality of guide vanes 220 are spaced apart and distributed around the periphery of the first filter element 120, and a discharge channel 114 is formed by enclosing between two adjacent guide vanes 220. The first chamber 1121 is communicated with the second chamber 1122 through the discharge channel 114. By arranging a plurality of guide vanes 220 at intervals on the partition plate 113, the plurality of guide vanes 220 can guide the fluid in the second channel 130, so that the fluid mixed with solid particles in the second channel 130 is diverted into the second chamber 1122, realizing the effective separation of the fluid by the separator 100.

[0118] Furthermore, the extending direction of the discharge channel 114 is different from the direction of the fluid in the second channel 130, so as to effectively reduce the flow velocity of the fluid flowing into the discharge channel 114, and further weaken the disturbance of the strong swirling flow in the first chamber 1121 to the fluid in the second chamber 1122. When the solid particles flow into the second chamber 1122 from the discharge channel 114, they can be deposited in the second chamber 1122, realizing the collection of the solid particles and further improving the separation effect and separation efficiency of the separator 100.

[0119] Embodiment Eight:

[0120] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 shown, on the basis of any one of the above embodiments, further, the driving device 160 includes a motor 161 and a rotating shaft 162. Among them, the rotating shaft 162 is connected to the output end of the motor 161, and the first support member 1511 is connected to the rotating shaft 162.

[0121] In this embodiment, it is defined that the driving device 160 includes a motor 161 and a rotating shaft 162. Specifically, the rotating shaft 162 is connected to the output end of the motor 161, so that the rotating shaft 162 can rotate under the drive of the motor 161. The first support member 1511 is connected to the rotating shaft 162, so that when the rotating shaft 162 rotates, it can drive the first support member 1511 to rotate. The rotation of the first support member 1511 can drive a plurality of first blades 1512 to rotate to disturb the fluid in the first channel, so as to perform backwashing on the first filter element 120 and realize the automatic cleaning of the first filter element 120.

[0122] Further, the second support member 1541 is connected to the rotating shaft 162. That is to say, driven by the motor 161, the rotating shaft 162 can drive the first support member 1511 and the second support member 1541 to rotate, and further drive the first blade 1512 and the second blade 1542 to rotate. The rotation of the first blade 1512 can throw the fluid in the first channel towards the inner wall of the first filter element 120, and the rotation of the second blade 1542 can throw the fluid in the third channel towards the inner wall of the second filter element 210, thereby achieving a reverse flushing effect on the first filter element 120 and the second filter element 210, and realizing the cleaning of the first filter element 120 and the second filter element 210.

[0123] In addition, sharing a rotating shaft 162 for the first impeller 151 and the second impeller 154 can simplify the structure of the separator 100 on the basis of realizing the cleaning of the first filter element 120 and the second filter element 210, and thus reduce the cost of the separator 100.

[0124] It should be noted that the first support member 1511 can be fixedly connected to the rotating shaft 162 by screws, and the second support member 1541 can also be fixedly connected to the rotating shaft 162 by screws, so as to ensure the connection effect between the rotating shaft 162 and the first support member 1511 and the second support member 1541, and effectively realize power transmission.

[0125] In addition, the separator 100 further includes a bearing 163 and an oil seal bearing 164. The bearing 163 is arranged on the housing 110 and sleeved on the rotating shaft 162, so as to ensure the stability of the rotation of the rotating shaft 162 and extend the service life of the rotating shaft 162. The oil seal bearing 164 can seal the chamber 112 at the connection between the rotating shaft 162 and the housing 110 on the basis of ensuring the stable rotation of the rotating shaft 162.

[0126] Embodiment Nine:

[0127] According to the second aspect of the present invention, a household appliance is provided, including the separator 100 provided in any of the above embodiments, and thus has all the beneficial technical effects of the separator 100, which will not be elaborated here.

[0128] Further, the household appliance further includes a base 310, and the separator 100 is arranged on the base 310; wherein, the central axis of the rotating shaft 162 of the driving device 160 is parallel to the plane where the bottom wall of the base 310 is located.

[0129] The household device provided by the embodiment of the present invention includes a separator 100 and a base 310. Specifically, the separator 100 is disposed on the base 310, and the central axis of the rotating shaft 162 of the driving device 160 is parallel to the plane where the bottom wall of the base 310 is located, that is, the central axis of the housing 110 is parallel to the horizontal plane. That is to say, when the separator 100 is horizontally placed on the base 310 of the household device, compared with vertically disposing the separator 100 on the base 310, when the separator 100 is horizontally placed, at the same height dimension of the base 310 of the household device, the height of the feed port of the separator 100 is lower, so that the liquid level depth at the feed port is deeper, and when the fluid enters the second channel 130 from the feed port, air is not easily brought in, further improving the separation efficiency of the separator 100.

[0130] Specifically, the household device is a dishwasher 300. The dishwasher 300 includes a base 310, and the separator 100 is horizontally placed on the base 310. At the same height dimension of the dishwasher 300, the height of the feed port of the separator 100 is lower. When the water sprayed on the tableware 380 falls down, air is not easily brought in, weakening the air suction effect of the washing pump 320 and improving the performance of the washing pump 320.

[0131] As Figure 8 shown, the dishwasher 300 includes a base 310, a washing pump 320, a pipeline 370, a lower spray arm 340, a middle spray arm 350, an upper spray arm 360, a spray nozzle 341 and a chassis 330. The tableware 380 is placed in the dishwasher 300. The process of circulating washing and filtering of the dishwasher 300 is as follows: Water flows out from the washing pump 320, enters the lower spray arm 340, the middle spray arm 350 and the upper spray arm 360 respectively through the pipeline 370, and then is sprayed on the tableware 380 through the spray nozzle 341. The contaminants washed down fall into the chassis 330 together with the water, and then enter the separator 100 together with the water. The contaminants are separated and stored in the second chamber 1122 of the separator 100, and the clean water flows into the washing pump 320 through the outlet part 180 of the separator 100 to start the next cycle. Among them, the arrow indicates the flow direction of the water flow.

[0132] In the related art, the filtering method of the dishwasher 300 is circular filtering, and the water flowing out contains some contaminants, which will cause secondary pollution to the tableware 380. After the separator 100 of any one of the embodiments in the first aspect is applied to the dishwasher 300 in this application, the sewage passes through the separator 100, and all contaminants are intercepted. The water flowing out is clean water and will not cause secondary pollution to the tableware 380, which is beneficial to improving the washing effect, reducing the washing time and saving water consumption.

[0133] Among them, the household device includes but is not limited to a dishwasher 300, a washing machine and a clothes dryer, etc.

[0134] In the description of this specification, terms such as "connection", "installation", "fixation", etc. shall be understood in a broad sense.
