Description

Technical Field

[0001] The present invention relates to the technical field of cyclone separators, and more particularly, to a cyclone separator and a dishwasher. Background Art

[0002] Currently, a cyclone separator is a device used for separating gas-solid systems or liquid-solid systems.

[0003] First, when using a cyclone separator alone to separate solid particles in a fluid, when the density of the solid particles is only slightly greater than the density of the fluid and the solid particles are flaky, the centrifugal force acting on the solid particles weakens, causing the solid particles located at the periphery to be unable to descend, and the solid particles will flow out from the outlet of the cyclone separator, making it impossible to achieve solid-liquid separation.

[0004] Second, the single separation efficiency of the cyclone separator itself is less than 100%, and pollutants cannot be filtered cleanly in a single time, so it will cause secondary pollution to downstream components. Summary of the Invention

[0005] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0006] To this end, in the first aspect of the present invention, a cyclone separator is provided.

[0007] In the second aspect of the present invention, a dishwasher is provided.

[0008] In view of this, according to the first aspect of the present invention, a cyclone separator is provided, which includes a first housing, a second housing, a first filter element, a flow-through channel, an input pipe, an output pipe, and a reflux part. The second housing is disposed inside the first housing, and a dirt collection chamber is included between the second housing and the first housing; the first filter element is disposed inside the second housing, and the first filter element encloses to form a first filtration chamber; the flow-through channel is located between the first filter element and the second housing, and the flow-through channel communicates with the first filtration chamber through filter holes, and the dirt collection chamber communicates with the flow-through channel; the input pipe communicates with the flow-through channel, and a flowing medium enters the cyclone separator through the input pipe and forms a swirl in the flow-through channel; the output pipe communicates with the first filtration chamber, and the flowing medium is discharged from the cyclone separator through the output pipe; the flowing medium flows from the dirt collection chamber to the output pipe through the reflux part.

[0009] The cyclone separator provided by the present invention includes a first housing, a second housing, a first filter element, and a reflux portion. The second housing is disposed inside the first housing, and there is a dirt collection chamber between the second housing and the first housing. The dirt collection chamber is used for collecting pollutant particles. The first filter element is disposed inside the second housing. The first filter element has filter holes. When the flowing medium passes through the first filter element, the liquid can enter the first filter chamber of the first filter element through the filter holes, and the pollutant particles will be blocked outside the first filter element. There is a flow-through channel between the first filter element and the second housing, and the flow-through channel communicates with the first filter chamber through the filter holes.

[0010] Further, the cyclone separator further includes an input pipe, and the input pipe can be disposed on the first housing. Or the input pipe is disposed on the second housing. Or the input pipe is located on both the first housing and the second housing at the same time. The input pipe communicates with the flow-through channel. A pumping assembly is disposed at the input pipe or the output pipe of the cyclone separator. The pumping assembly can pressurize the flowing medium so as to disturb the flowing medium in the flow-through channel. Specifically, when the pumping assembly is disposed at the input pipe, the pressurized flowing medium will enter the flow-through channel tangentially along the inner wall of the second housing through the input pipe, and then in the flow-through channel, that is, flow circumferentially along the inner wall of the second housing to form a swirl. It should be noted that the flow-through channel is an annular channel, and the flowing medium forms a swirl in the annular channel and then enters the first filter chamber through the filter holes on the first filter element.

[0011] Further, the cyclone separator further includes a reflux portion. The reflux portion guides the flowing medium from the dirt collection chamber to the output pipe. Since the reflux portion is in a low-pressure area and the flow-through channel is in a high-pressure area, the flowing medium has a tendency to flow from the high-pressure area to the low-pressure area. Under this flowing tendency, although the centrifugal force of the solid particles with a density slightly greater than that of the fluid in the flow-through channel weakens, the solid particles can still flow downward toward the dirt collection chamber, thereby realizing solid-liquid separation. At the same time, it can also ensure the filtering effect of the first filter element, prevent the phenomenon of the first filter element being blocked by pollutant particles, and at the same time bring the pollutants in the flow-through channel into the dirt collection chamber to prevent the pollutant particles from entering the filter chamber and causing secondary pollution to the downstream components.

[0012] Specifically, during the operation of the cyclone separator, due to the flow characteristics of the swirl, the area near the rotation center line of the fluid in the first filter chamber is a low-pressure area. The reflux portion can be disposed in the low-pressure area, so that the reflux portion is in a region with a lower pressure to guide the flowing medium at the flow-through channel to flow into the dirt collection chamber. Or, the reflux portion can be disposed in the dirt collection chamber. The reflux portion can be connected to a negative pressure device, and the negative pressure device can make the position where the reflux portion is located a low-pressure area, and thus can also drive the flowing medium in the flow-through channel to flow toward the dirt collection chamber. The installation position of the reflux portion is diverse and will not be enumerated exhaustively.

[0013] It should also be noted that the fluid entering the first filtering chamber will directly flow out from the output pipe via the first filtering chamber. Among them, the first end of the output pipe extends into the first filtering chamber, and the second end of the output pipe is communicated with the external drainage pipeline.

[0014] In a possible design, further, the reflux part includes a reflux port arranged on the output pipe, and the reflux port is arranged outside the first filtering chamber.

[0015] In a possible design, further, the output pipe includes a connected outer pipe and inner pipe. At least a part of the inner pipe is located outside the first filtering chamber and within the first housing. The reflux port is opened on the inner pipe and is located outside the first filtering chamber, and the outer pipe is located outside the first housing.

[0016] In a possible design, further, the inner pipe is coaxially arranged with the first filtering chamber.

[0017] In a possible design, further, the cyclone separator further includes a second filtering member, and the second filtering member is arranged between the dirt collection chamber and the reflux part. After the flowing medium passes through the second filtering member, it flows from the reflux part to the output pipe.

[0018] In a possible design, further, the cyclone separator further includes a sewage discharge port, and the sewage discharge port is communicated with the dirt collection chamber.

[0019] In a possible design, further, a part of the second housing protrudes away from the first filtering member to form a buffer part.

[0020] In a possible design, further, the cyclone separator further includes a guiding part, and the guiding part is located in the first filtering chamber.

[0021] In a possible design, further, the guiding part includes a cone, the top of the cone is close to the output pipe, and the bottom of the cone is far from the output pipe.

[0022] In a possible design, further, the cyclone separator further includes a bottom shell, the bottom shell is connected to the first housing, and the second housing is located between the bottom shell and the first housing; among them, a passage is formed between the bottom shell and the second housing to connect the flow passage and the dirt collection chamber, and the reflux part is arranged away from the bottom shell.

[0023] In a possible design, further, the cyclone separator further includes a guiding member, which is arranged on the bottom shell and is located in the passage.

[0024] In a possible design, further, the guiding member includes a plurality of guide vanes, and the plurality of guide vanes are arranged on the bottom shell at intervals. The tangential direction of the guide vane inlet is opposite to the fluid rotation direction in the second housing.

[0025] In a possible design, further, the cyclone separator further includes a driving member and a first cleaning member. The first cleaning member is attached to the outer wall of the first filter member, and the driving member is used to drive the first cleaning member to move relative to the first filter member.

[0026] According to a second aspect of the present invention, there is provided a dishwasher, including the cyclone separator provided in the first aspect above and a pumping assembly. The pumping assembly is communicated with the output pipe or the input pipe of the cyclone separator, and the pumping assembly is used to pump a flowing medium.

[0027] In a possible design, further, the input pipe of the cyclone separator is arranged lower than the output pipe of the cyclone separator.

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.

[0056] 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.

[0057] Refer to the following Figures 1 to 7 to describe the cyclone separator 1 and the dishwasher 2 provided according to some embodiments of the present invention.

[0058] According to the first aspect of the present invention, as Figure 2 and Figure 4 shown, a cyclone separator 1 is provided, which includes a first housing 11, a second housing 12, a first filter member 131, a flow-through channel 140, an input pipe 142, an output pipe 143, and a reflux portion 15. The second housing 12 is disposed within the first housing 11, and a dirt collection chamber 10 is included between the second housing 12 and the first housing 11. The first filter member 131 is provided within the second housing 12, and the first filter member 131 encloses to form a first filter chamber. The flow-through channel 140 is located between the first filter member 131 and the second housing 12, and the flow-through channel 140 communicates with the first filter chamber through filter holes. The dirt collection chamber 10 communicates with the flow-through channel 140. The input pipe 142 communicates with the flow-through channel 140, and the flowing medium enters the cyclone separator 1 through the input pipe 142 and forms a swirl within the flow-through channel 140. The output pipe 143 communicates with the first filter chamber, and the flowing medium is discharged from the cyclone separator 1 through the output pipe 143. The flowing medium flows from the dirt collection chamber 10 to the output pipe 143 through the reflux portion 15.

[0059] The cyclone separator 1 provided by the present invention includes a first housing 11, a second housing 12, a first filter member 131, and a reflux portion 15. The second housing 12 is provided inside the first housing 11, and a dirt collection chamber 10 is provided between the second housing 12 and the first housing 11. The dirt collection chamber 10 is used for collecting pollutant particles. The first filter member 131 is provided within the second housing 12. The first filter member 131 has filter holes. When the flowing medium flows through the first filter member 131, the liquid can enter the first filter chamber of the first filter member 131 through the filter holes, and the pollutant particles will be blocked outside the first filter member 131. A flow-through channel 140 is provided between the first filter member 131 and the second housing 12, and the flow-through channel 140 communicates with the first filter chamber through filter holes.

[0060] Further, the cyclone separator 1 further includes an input pipe 142, and the input pipe 142 can be provided on the first housing 11. Or the input pipe 142 is provided on the second housing 12. Or the input pipe 142 is located on both the first housing 11 and the second housing 12 at the same time. The input pipe 142 communicates with the flow-through channel 140. Among them, in some embodiments, at least a part of the output pipe 143 extends into the first filtration chamber, so that the output pipe 143 communicates with the filtration chamber, simplifying the structure. A pumping assembly is provided at the input pipe 142 or the output pipe 143 of the cyclone separator 1, and the pumping assembly can pressurize the flowing medium, thereby disturbing the flowing medium in the flow-through channel 140. Specifically, when the pumping assembly is provided at the input pipe 142, the pressurized flowing medium will enter the flow-through channel 140 tangentially along the inner wall of the second housing 12 via the input pipe 142, and then in the flow-through channel 140, that is, flow circumferentially along the inner wall of the second housing 12 to form a swirl. It should be noted that the flow-through channel 140 is an annular channel, and the flowing medium forms a swirl in the annular channel, and then enters the first filtration chamber through the filter holes on the first filter element 131.

[0061] Further, the cyclone separator 1 further includes a reflux portion 15, and the reflux portion 15 guides the flowing medium to flow from the dirt collection chamber 10 to the output pipe 143. Since the reflux portion 15 is in a low-pressure area and the flow-through channel 140 is in a high-pressure area, the flowing medium has a tendency to flow from the high-pressure area to the low-pressure area. Under this flowing tendency, although the centrifugal force of the solid particles with a density slightly greater than that of the fluid in the flow-through channel 140 weakens, the solid particles can still flow downward toward the dirt collection chamber 10, thereby realizing solid-liquid separation. At the same time, it can also ensure the filtration effect of the first filter element 131, prevent the phenomenon of the first filter element 131 being blocked by pollutant particles, and at the same time bring the pollutants in the flow-through channel 140 into the dirt collection chamber 10 to prevent the pollutant particles from entering the filtration chamber and causing secondary pollution to the downstream components.

[0062] Specifically, during the operation of the cyclone separator 1, due to the flow characteristics of the swirl, the area near the rotation center line of the fluid in the first filtration chamber is a low-pressure area. The reflux portion 15 can be provided in the low-pressure area, so that the reflux portion 15 is in a region with a lower pressure to guide the flowing medium at the flow-through channel 140 into the dirt collection chamber 10. Or, the reflux portion 15 can be provided in the dirt collection chamber 10, and the reflux portion 15 can be connected to a negative pressure device, and the negative pressure device can make the position where the reflux portion 15 is located a low-pressure area, and thus can also drive the flowing medium in the flow-through channel 140 to flow toward the dirt collection chamber 10. The installation position of the reflux portion 15 is diverse, as long as it can guide the flowing medium to flow from the flow-through channel 140 toward the dirt collection chamber 10, and the specific installation position of the reflux portion 15 will not be enumerated.

[0063] It should also be noted that the fluid entering the first filtering chamber will directly flow out from the output pipe 143 through the first filtering chamber. Among them, the first end of the output pipe 143 extends into the first filtering chamber, and the second end of the output pipe 143 is communicated with the external drainage pipeline.

[0064] Furthermore, as Figure 2 and Figure 4 shown, the reflux part 15 includes a reflux port arranged on the output pipe 143, and the reflux port is arranged outside the first filtering chamber.

[0065] In this embodiment, the output pipe 143 includes a first end facing the first filtering element 131 and a second end communicated with the drainage pipeline. The first end of the output pipe 143 extends into the first filtering chamber. The reflux port is arranged on the output pipe 143 and is located outside the first filtering chamber. During the flow of the fluid, the fluid can enter through the first end of the output pipe 143 and then flow out through the second end.

[0066] Furthermore, the output pipe 143 can be an integral pipe section or can be composed of two spliced pipe sections, as Figure 4As shown, specifically, the outlet pipe 143 includes an inner pipe 1432 and an outer pipe 1431 that are connected and communicate with each other. The reflux port is provided on the inner pipe 1432. At least a part of the inner pipe 1432 is located outside the first filtration chamber and inside the first housing 11, and the outer pipe 1431 is located outside the first housing 11. The reflux port is provided on the inner pipe 1432 and is located outside the first filtration chamber. Among them, there is a gap between the inner pipe 1432 and the first filter element 131, so that the inner pipe 1432 does not closely adhere to the first filter element 131, avoiding clogging the filter holes on the first filter element 131 due to the setting of the inner pipe 1432. The fluid can flow in the gap to meet the filtration efficiency of the cyclone separator 1. It should be noted that there is a reflux channel 141 between the part of the inner pipe 1432 located outside the first filtration chamber and the first housing 11. The reflux channel 141 communicates with the dirt collection chamber 10. A reflux port is provided on the part of the inner pipe 1432 corresponding to the reflux channel 141. Since the inner pipe 1432 is coaxially arranged with the first filtration chamber, according to the flow characteristics of the swirl, the area near the rotation center line of the fluid in the first filtration chamber is a low-pressure area. That is to say, the reflux port is in the low-pressure area in the filtration chamber. The reflux port is used for fluid circulation. During the operation of the cyclone separator 1, the flowing medium entering the flow-through channel 140 will form a swirl. The flowing medium will pass through the first filter element 131, enter the first filtration chamber, and then flow out through the inner pipe 1432 and the outer pipe 1431. At the same time, under the guiding action of the reflux part 15, the flowing medium in the flow-through channel 140 flows through the dirt collection chamber 10 and the reflux channel 141 to the reflux port, and then flows out through the inner pipe 1432 and the outer pipe 1431. Based on the conservation of flow rate, a flow direction towards the dirt collection chamber 10 will be formed in the flow-through channel 140 to supplement the flow rate in the reflux port. The flowing medium flows towards the dirt collection chamber 10 in the flow-through channel 140, and pollutants particles can be carried into the dirt collection chamber 10 during the flowing process, so that the amount of pollutants particles separated into the dirt collection chamber 10 per unit time can be increased, and the clogging of the first filter element 131 can be effectively alleviated.

[0067] Conceivably, the reflux port is a long strip-shaped hole, a circular hole, etc.

[0068] Furthermore, as Figure 4 shown, the inner pipe 1432 includes a pipe body 1432a and an assembly convex part 1432b. The reflux port is provided on the pipe body 1432a. One end of the pipe body 1432a is arranged on the first housing 11. The assembly convex part 1432b is provided on the outer wall of the pipe body 1432a, and the assembly convex part 1432b is connected to the first filter element 131.

[0069] In this embodiment, the inner tube 1432 includes a tube body 1432a and a fitting protrusion 1432b. The tube body 1432a is a circular tube, and a return port is provided on the tube body 1432a. The fluid can enter the interior of the tube body 1432a through the return port and then flow to the outer tube 1431. The return port corresponding to the return channel 141 is provided on the tube body 1432a. Since the return port is used for the fluid flowing from the return channel 141 to circulate, it only needs to be provided for the return channel 141, and no other positions need to be provided, reducing the processing difficulty and avoiding affecting the overall structural strength due to the large opening area of the tube body 1432a. The fitting protrusion 1432b is provided on the outer wall of the tube body 1432a, and the fitting protrusion 1432b is used for the fixed connection between the tube body 1432a and the first filter element 131. The components with different functions are relatively independent, avoiding mutual interference.

[0070] It is worth noting that the fitting protrusion 1432b extends circumferentially around the tube body 1432a, so as to provide all-round position fixation for the tube body 1432a. Further, the fitting protrusion 1432b is located at the middle position of the tube body 1432a, so that the tube body 1432a on both sides of the fitting protrusion 1432b can be relatively balanced in force.

[0071] Further, as Figure 2 and Figure 4 shown, the cyclone separator 1 further includes a second filter element 132. The second filter element 132 is provided between the dirt collection chamber 10 and the return part 15. After the flowing medium passes through the second filter element 132, it flows from the return part 15 to the output pipe 143.

[0072] In this embodiment, the cyclone separator 1 further includes a second filter element 132. The second filter element 132 is provided between the dirt collection chamber 10 and the return part 15. Under the action of the return part 15, the flowing medium flows from the flow-through channel 140 towards the dirt collection chamber 10. The second filter element 132 can filter the flowing medium flowing from the dirt collection chamber 10 to the output pipe 143, further improving the filtering effect of the cyclone separator 1.

[0073] Specifically, the second filter element 132 is connected to the first housing 11 and is correspondingly arranged in the reflux channel 141. The second filter element 132 has a second filter chamber and is mainly used to intercept pollutant particles in the dirt collection chamber 10. The flowing medium from the dirt collection chamber 10 flows through the reflux channel 141 to the second filter element 132, and the fluid passing through the second filter element 132 enters the second filter chamber and then flows out through the reflux port into the output pipe 143. The first filter element 131 is located between the second filter element 132 and the second housing 12. That is to say, compared with the second filter element 132, the first filter element 131 is arranged farther away from the output pipe. The first filter element 131 is correspondingly arranged for the flow-through channel 140. The first filter element 131 includes a first filter chamber, and the second filter chamber communicates with the first filter chamber. During the forward flow process, the flowing medium enters the first filter chamber through the first filter element 131, then flows to the second filter chamber, and finally flows out through the output pipe 143. The first filter element 131 filters particles larger than the mesh size to achieve a complete primary filtration. At the same time, the first filter element 131 can also significantly weaken the swirl intensity in the second housing 12 and can significantly reduce the resistance of the entire cyclone separator 1. Under the action of the reflux part 15, the flowing medium in the flow-through channel 140 can flow towards the dirt collection chamber 10. The flowing medium in the dirt collection chamber 10 will flow through the reflux channel 141 to the second filter element 132, and the pollutant particles are intercepted by the second filter element 132. The fluid passes through the second filter element 132 and enters the second filter chamber, and then flows out through the reflux port by the output pipe 143.

[0074] At the same time, the second filter element 132 and the first filter element 131 are used in combination in the cyclone separator 1, which can reduce the assembly difficulty and the manufacturing difficulty.

[0075] It should be noted that the second filter element 132 can assist the reflux part 15 to ensure that in the large reflux volume formed due to the setting of the reflux port, the pollutant particles can be intercepted, so that the pollutant particles brought during the reflux process can be intercepted at the reflux channel 141 and then can be collected in the dirt collection chamber 10.

[0076] It should be noted that as Figure 2 and Figure 4 shown, the first filter element 131 and the second filter element 132 are combined to form the filtering mechanism of the cyclone separator 1. That is, the first filter element 131 and the second filter element 132 are two independent components. During the splicing process of the two, there will inevitably be a splicing and mating position. A part of the reflux part 15 can be clamped between the first filter element 131 and the second filter element 132, so that there is no need to additionally add mating components for the fixed installation of the reflux part 15. The splicing and mating position of the first filter element 131 and the second filter element 132 can be effectively utilized, simplifying the product structure and improving the structural compactness of the overall product.

[0077] Further, as Figure 1 , Figure 2 and Figure 4 shown, the cyclone separator 1 further includes a blowdown port 144, and the blowdown port 144 communicates with the dirt collection chamber 10.

[0078] In this embodiment, the cyclone separator 1 further includes a blowdown port 144. The blowdown port 144 is provided on the first housing 11, and the blowdown port 144 communicates with the dirt collection chamber 10. Pollutant particles intercepted by the second filter element 132 and the first filter element 131 will be deposited in the dirt collection chamber 10. During the operation of the cyclone separator 1, the blowdown port 144 can be intermittently opened, and after the pollutant particles have accumulated for a certain period of time, the pollutants in the dirt collection chamber 10 can be concentrated and discharged.

[0079] It should be noted that the flowing medium can enter the interior of the cyclone separator 1 through the input pipe. After being filtered by the first filter element 131, the flowing medium is generally divided into fluid and pollutant particles (solids). The fluid will flow out through the output pipe, while the solids will be discharged from the cyclone separator 1 through the blowdown port 144.

[0080] Further, the blowdown port 144 corresponds to the reflux portion 15, so that more impurities can be discharged.

[0081] Further, a part of the second housing 12 protrudes away from the first filter element 131 to form a buffer portion 12a.

[0082] In this embodiment, a part of the second housing 12 protrudes away from the first filter element 131 to form a buffer portion 12a. The buffer portion 12a itself can form a buffer groove, and the buffer groove is used to increase the volume of the flow passage 140, so that a large amount of flowing medium entering the flow passage 140 can be buffered well, preventing the flowing medium from directly hitting the first filter element 131 due to future swirling, avoiding pollutants from adhering to the first filter element 131 and blocking the flow, and at the same time also avoiding a large amount of flowing medium with too high a flow rate from directly hitting the first filter element 131 and threatening the structural strength of the first filter element 131.

[0083] Further, as Figure 2 and Figure 4 shown, the cyclone separator 1 further includes a diversion portion 16, and the diversion portion 16 is located in the first filter chamber.

[0084] In this embodiment, the cyclone separator 1 further includes a diversion part 16, and the diversion part 16 is located in the first filtration chamber. The diversion part 16 and the second housing 12 form a channel that contracts outward. When the rotating fluid in the flow channel 140 moves from left to right, it tends to move in the direction of the dirt collection chamber 10. At this time, the particles in the flowing medium will also flow towards the dirt collection chamber 10, which is consistent with the direction of centrifugal separation, thereby enhancing the effect of centrifugal separation.

[0085] Further, as Figure 4 and Figure 6 shown, the diversion part 16 includes a cone, the top of the cone is close to the output pipe 143, and the bottom of the cone is far from the output pipe 143.

[0086] In this embodiment, the diversion part 16 includes a cone. Regarding the definition of a cone, the set formed by the surface obtained by rotating the other two sides 360° with the straight line where the right-angled side of a right-angled triangle is located as the rotation axis is called a cone. The rotation axis is called the axis of the cone, the surface formed by rotating the side perpendicular to the axis is called the bottom surface of the cone, and the surface formed by rotating the side not perpendicular to the axis is called the side surface of the cone. Among them, the top of the cone is located in the first filtration chamber, and the side surface of the cone forms a drainage surface, and the drainage surface can guide the fluid to flow from the flow channel 140 towards the dirt collection chamber 10.

[0087] At the same time, since the diversion part 16 is conical, the cone can also assist the fluid in the filtration chamber to better form a swirl, so that the flaky pollutant particles in the flow channel 140 can be thrown to the outside under the action of centrifugal force, and at the same time, the fluid can also flow along the drainage surface of the cone towards the output pipe.

[0088] It should be noted that when the diversion part 16 is a cone, the space formed between the cone and the second housing 12 is tapered from the top (left) of the cone to the bottom (right) of the cone. When the rotating fluid inside the flow channel 140 moves in the direction from left to right, it will tend to the bottom of the cone, that is, move in the direction of the dirt collection chamber 10, so that the particles in the flowing medium move towards the dirt collection chamber, which is consistent with the direction of centrifugal separation, thereby enhancing the effect of centrifugal separation.

[0089] Further, as Figure 2 、 Figure 3 、 Figure 4 and Figure 6 shown, the cyclone separator 1 further includes a bottom shell 120. The bottom shell 120 is connected to the first housing 11, and the second housing 12 is located between the bottom shell 120 and the first housing 11; wherein, a passage 145 is formed between the bottom shell 120 and the second housing 12 to connect the flow channel 140 and the dirt collection chamber 10, and the reflux part 15 is arranged far from the bottom shell 120.

[0090] In this embodiment, the cyclone separator 1 further includes a bottom shell 120, which is detachably connected to the first shell 11, and the bottom shell 120 is located on the side of the first shell 11 away from the output pipe 143, and the guide portion 16 is provided on the bottom shell 120. The second shell 12 is located between the bottom shell 120 and the first shell 11, and the second shell 12 is detachably connected to the first shell 11. Specifically, the first shell 11 is provided with an escape port 110, and a part of the second shell 12 forms a connecting buckle 12b, and the connecting buckle 12b is clamped on the first shell 11 through the escape port 110, so as to realize the installation between the second shell 12 and the first shell 11. It should be noted that the number of the connecting buckles 12b is multiple, the number of the escape ports 110 is multiple, and the multiple connecting buckles 12b and the multiple escape ports 110 are arranged one by one, so as to realize the omnidirectional position stability of the second shell 12 on the first shell 11. The bottom shell 120, the first shell 11 and the second shell 12 are combined to form a connected flow channel 140, a passage 145 and a sewage collecting chamber 10, which can reduce the disturbance of the strong vortex in the flow channel 140 to the sewage collecting chamber 10, so that the pollutant particles in the sewage collecting chamber 10 are deposited and will not be discharged.

[0091] Furthermore, a portion of the first filter element 131 is located between the bottom shell 120 and the second shell 12 , and a portion of the second filter element 132 is located inside the first shell 11 .

[0092] Furthermore, if Figure 6 As shown, the cyclone separator 1 further includes a flow guide 122 , which is disposed on the bottom shell 120 and located in the passage 145 .

[0093] In this embodiment, the cyclone separator 1 also includes a flow guide 122, which is arranged on the bottom shell 120 and located in the passage 145, that is, the flow guide 122 is arranged toward the flow channel 140, and the flow guide 122 can weaken the flow velocity of the flowing medium. Since the flow velocity of the flowing medium entering the flow channel 140 is too fast, if the flowing medium with too fast flow velocity directly flows into the sewage collecting chamber 10, it will bring a large disturbance to the sewage collecting chamber 10, so that the pollutant particles that have been deposited in the sewage collecting chamber 10 are disturbed again. By setting the flow guide 122, the flow of the flowing medium with a faster flow velocity can be well limited, so that the flow velocity of the flowing medium entering the sewage collecting chamber 10 is weakened, so that the pollutant particles can be easily deposited after entering the sewage collecting chamber 10, which is convenient for collecting the pollutant particles.

[0094] Furthermore, the flow guide 122 includes a plurality of guide vanes 122a, which are arranged at intervals on the bottom shell 120. The tangential direction of the inlet of the guide vane 122a is opposite to the rotation direction of the fluid in the second shell 12.

[0095] In this embodiment, the flow guide member 122 includes a plurality of guide vanes 122a, and the plurality of guide vanes 122a are arranged at intervals on the bottom shell 120. Specifically, the plurality of guide vanes 122a are arranged at intervals on the periphery of the flow guiding portion 16. A guide vane channel is formed between two adjacent guide vanes 122a, and the guide vane channel communicates with the flow-through channel 140. The flowing medium from the flow-through channel 140 can enter the dirt collection cavity 10 through the guide vane channel. The guide vane channel formed by two adjacent guide vanes 122a can weaken the flow velocity of the flowing medium.

[0096] Further, each of the plurality of guide vanes 122a includes a plurality of connected flow guiding segments, and the plurality of flow guiding segments include a leading edge straight segment facing the flow guiding portion 16. The leading edge straight segment is the inlet of the guide vane 122a, and the leading edge straight segment is a straight line segment. For the leading edge straight segment, it has a straight line direction extending away from the flow guiding portion 16, that is, the tangential direction of the inlet of the guide vane 122a. For the rotating fluid in the first filter cavity, when the fluid flows to the end point of the leading edge straight segment close to the flow guiding portion 16 during rotation, it will have a tangential direction opposite to the aforementioned straight line direction. By making the extension direction of the leading edge straight segment associated with the tangential direction of the rotating fluid, the speed limit of the flowing medium about to flow into the dirt collection cavity 10 is realized, and finally the strong swirl in the flow-through channel 140's disturbance to the dirt collection cavity 10 is weakened, so that the pollutant particles can be deposited after entering the dirt collection cavity 10, thereby realizing the collection of the particles.

[0097] Further, as Figure 2 and Figure 4 shown, the cyclone separator 1 further includes a driving member 17 and a first cleaning member 181. The first cleaning member 181 is attached to the outer wall of the first filter member 131, and the driving member 17 is used to drive the first cleaning member 181 to move relative to the first filter member 131.

[0098] In this embodiment, during the use of the cyclone separator 1, there is still a certain probability that a small amount of pollutants will adhere to the first filter member 131. If it runs for a long time and multiple times, more pollutants may accumulate on the first filter member 131. Although under the scouring action of the fluid, part of the pollutants will be washed back into the dirt collection cavity 10, there will still be some pollutants that are difficult to detach from the first filter member 131 under the scouring action of the fluid. Therefore, the cyclone separator 1 further includes a driving member 17 and a first cleaning member 181. The first cleaning member 181 is attached to the outer wall of the first filter member 131. When the driving member 17 drives the first cleaning member 181 to move relative to the first filter member 131, the first cleaning member 181 can clean the outer wall of the first filter member 131, thereby separating the stubborn pollutants attached to the first filter member 131. The shed pollutants can enter the dirt collection cavity 10 through the flow-through channel 140 and the guide vane 122a channel under the action of the strong swirl, and thus be collected.

[0099] Further, as shown in Figure 2 and Figure 4 , the first cleaning member is located in the flow-through channel 140. The first cleaning member 181 is attached to the outer wall of the first filter member 131, and the first cleaning member 181 is used to clean the outer wall of the first filter member 131. The cyclone separator 1 further includes a first transmission assembly. The driving member 17 is connected to the first cleaning member 181 through the first transmission assembly. Through the first transmission assembly, flexible arrangement of the driving member 17, the first cleaning member 181, and the first filter member 131 can be achieved, with higher degrees of freedom, and the steering of power output is achieved through the first transmission assembly.

[0100] Further, the cyclone separator 1 further includes a second cleaning member 182. The second cleaning member 182 is located in the return channel 141. The second cleaning member 182 is attached to the outer wall of the second filter member 132, and the second cleaning member 182 is used to clean the outer wall of the second filter member 132. The cyclone separator 1 further includes a second transmission assembly. The driving member 17 is connected to the second cleaning member 182 through the second transmission assembly. Through the second transmission assembly, flexible arrangement of the driving member 17, the second cleaning member 182, and the second filter member 132 can be achieved, with higher degrees of freedom, and the steering of power output is achieved through the second transmission assembly.

[0101] It should be noted that through the first transmission assembly and the second transmission assembly, one driving member 17 can simultaneously drive two cleaning members (the first cleaning member 181 and the second cleaning member 182), realizing a one-drive-two driving mode, effectively improving the structural compactness of the cyclone separator 1.

[0102] Further, as shown in Figure 1 , Figure 4 and Figure 5 , the driving member 17 includes a driving motor. The first transmission assembly includes at least one first driving gear 191a and at least one first driven gear 191b. At least one first driving gear 191a is sleeved on the transmission shaft 171 of the driving motor. At least one first driven gear 191b is disposed on the first cleaning member 181, and at least one first driven gear 191b is correspondingly meshed and connected with at least one first driving gear 191a.

[0103] In this embodiment, the driving member 17 includes a driving motor, and the driving motor has the advantages of simple structure, small occupied space, and low cost.

[0104] It should be noted that the drive motor includes a drive shaft 171, on which a coupling 172, a bearing 174 and a seal 173 are sleeved. The coupling 172 is located outside the first housing 11, the bearing 174 is embedded in the outer wall of the first housing 11, the seal 173 is embedded in the inner wall of the first housing 11, and a part of the seal 173 contacts the return channel 141. Specifically, the seal 173 is an oil seal bearing 174.

[0105] Furthermore, the second transmission assembly includes a second driving gear 192a and a second driven gear 192b. The second driving gear 192a is sleeved on the drive shaft 171 of the drive motor, and the drive shaft 171 rotates synchronously with the second driving gear 192a. The second cleaning member 182 is also provided with a second driven gear 192b, and the second driven gear 192b can rotate synchronously with the second cleaning member 182. The second driven gear 192b is meshed and connected with the second driving gear 192a. During the operation of the drive motor, the drive shaft 171 rotates. At the same time, driven by the drive shaft 171, the second driving gear 192a and the second driven gear 192b also rotate synchronously, thereby driving the second cleaning member 182 to rotate relative to the second filter member 132, so that the adhered contaminants are separated from the outer wall of the second filter member 132.

[0106] Furthermore, the number of at least one first driven gear 191b is at least two, and at least two first driven gears 191b are arranged at intervals on the first filter member 131. The first cleaning member 181 is arranged between two adjacent first driven gears 191b.

[0107] In this embodiment, since the volume of the first filter member 131 is large and the length of the first filter member 131 is long, in order to ensure the effective cleaning of the entire outer wall of the first filter member 131 by the first cleaning member 181, the length of the first cleaning member 181 is long. At this time, in order to ensure the smooth scraping of the first cleaning member 181 relative to the first filter member 131 as a whole, the number of the first driven gears 191b is at least two, and the first cleaning member 181 is connected between two adjacent first driven gears 191b. At this time, the first driven gears 191b can transmit stable power to the first cleaning member 181, so that the first cleaning member 181 runs smoothly relative to the first filter member 131.

[0108] Furthermore, the cyclone separator 1 further includes at least one reinforcing rib, the at least one reinforcing rib is connected to the first cleaning member 181, and the at least one reinforcing rib extends around the outer wall of the first filter member 131.

[0109] In this embodiment, the cyclone separator 1 further includes at least one reinforcing rib. The reinforcing rib is connected to the first cleaning member 181 and moves synchronously with the first cleaning member 181. The reinforcing rib extends around the outer wall of the first filter member 131, thereby providing structural support for the first cleaning member 181 and preventing the first cleaning member 181 from deforming when it is difficult to separate due to a large amount of contaminants adhering to the first filter member 131.

[0110] According to the second aspect of the present invention, as Figure 7 shown, a dishwasher 2 is provided, which includes the cyclone separator 1 provided by any of the above designs and a pumping assembly 21. The pumping assembly 21 is in communication with the output pipe of the cyclone separator 1, and the pumping assembly 21 is used to pump a flowing medium.

[0111] The dishwasher 2 provided by the present invention includes the cyclone separator 1 provided by any of the above designs, and thus has all the beneficial effects of the cyclone separator 1, which will not be elaborated here.

[0112] Furthermore, the dishwasher 2 further includes a pumping assembly 21. The pumping assembly 21 is in communication with the output pipe of the cyclone separator 1. The pumping assembly 21 can pump the clean fluid separated by the cyclone separator 1 back to the area to be cleaned again, so that the inside of the dishwasher 2 is in a circulating filtration state, saving water resources.

[0113] Furthermore, the dishwasher 2 further includes a housing 22, a chassis 23 and an installation cavity. The chassis 23 is arranged inside the housing 22. The installation cavity is located between the bottom walls of the housing 22 and the chassis 23. The pumping assembly 21 and the cyclone separator 1 are located in the installation cavity. The input pipe of the cyclone separator 1 is arranged farther away from the chassis 23 than the output pipe of the cyclone separator 1.

[0114] In this embodiment, the dishwasher 2 further includes a housing 22, a chassis 23 and an installation cavity. The chassis 23 is arranged inside the housing 22. The housing 22 constitutes the outer contour of the dishwasher 2. The chassis 23 is used to divide the housing 22 into upper and lower cavity parts. The lower one is the installation cavity. The pumping assembly 21 and the cyclone separator 1 are located in the installation cavity. The cyclone separator 1 is placed horizontally in the installation cavity, that is, the central axis of the filtration cavity of the cyclone separator 1 extends in the horizontal direction. At this time, the input pipe of the cyclone separator 1 is arranged farther away from the chassis 23 than the output pipe of the cyclone separator 1. That is to say, compared with the output pipe, the input pipe is closer to the horizontal plane on which the dishwasher 2 is placed. At this time, the liquid level depth of the input pipe will be deeper. When the water sprayed on the tableware falls under the action of gravity, it is less likely to bring air into the interior of the cyclone separator 1 through the input pipe, thereby weakening the air suction effect of the pumping assembly 21 located downstream of the cyclone separator 1 and making the power performance of the pumping assembly 21 stronger.

[0115] Further, the dishwasher 2 further includes a washing cavity, a plurality of spray arms 24, and a liquid supply pipeline 25. The washing cavity is located on the side of the chassis 23 away from the cyclone separator 1. The plurality of spray arms 24 are spaced apart and distributed in the washing cavity. The plurality of spray arms 24 are communicated with the pump outlet of the pumping assembly 21 through the liquid supply pipeline 25.

[0116] In this embodiment, the dishwasher 2 further includes a washing cavity located above the chassis 23. The washing cavity is used for placing the dishes to be washed. The plurality of spray arms 24 are spaced apart and distributed in the washing cavity, so as to spray and wash the dishes to be washed at various positions in the washing cavity. The plurality of spray arms 24 are communicated with the pump outlet of the pumping assembly 21 through the liquid supply pipeline 25. After the filtered fluid in the cyclone separator 1 enters the pumping assembly 21 from the output pipe, it is pressurized inside the pumping assembly 21 and then flows out from the pump outlet, and then is conveyed to the plurality of spray arms 24 through the liquid supply pipeline 25, realizing spray cleaning.

[0117] Further, the plurality of spray arms 24 include a first spray arm 24 and a second spray arm 24, and the spraying directions of the first spray arm 24 and the second spray arm 24 are opposite.

[0118] In this embodiment, the plurality of spray arms 24 include a first spray arm 24 and a second spray arm 24, and the spraying directions of the first spray arm 24 and the second spray arm 24 are opposite, so as to be able to wash the dishes to be washed in different areas.

[0119] Specifically, the first spray arm 24 is located at the top of the washing cavity, and the first spray arm 24 sprays downward. The second spray arm 24 is arranged closer to the chassis 23 than the first spray arm 24, and the second spray arm 24 sprays upward. For the same dish to be washed, the first spray arm 24 can wash its upper surface, and the second spray arm 24 can wash its lower surface, so as to ensure targeted flushing of different areas of the dish to be washed and improve the cleaning effect of the dishwasher 2.

[0120] Specifically, the number of the first spray arm 24 and the second spray arm 24 is at least one, and they can be adaptively arranged according to the size of the space in the washing cavity.

[0121] Further, at least a part of the chassis 23 is recessed toward the inside of the installation cavity to form a receiving groove. The dishwasher 2 further includes a circulation port and a circulation pipeline 26. The circulation port is provided on the chassis 23 and communicated with the receiving groove. One end of the circulation pipeline 26 is connected to the chassis 23, the circulation pipeline 26 is communicated with the circulation port, and the other end of the circulation pipeline 26 is communicated with the input pipe.

[0122] In this embodiment, at least a part of the chassis 23 is recessed toward the interior of the installation cavity, that is, at least a part of the chassis 23 is recessed downward to form a receiving groove. The liquid sprayed by the multiple spray arms 24 in the washing cavity will fall into the receiving groove after flushing the dishes to be washed. A circulation port is also provided on the chassis 23. The circulation port is communicated with the input pipe of the hydrocyclone 1 through a circulation pipeline 26, so that the flowing medium with pollutant particles can be conveyed to the interior of the hydrocyclone 1 via the circulation port and the circulation pipeline 26, and then the circulating filtration and cleaning are realized through the filtration of the first filter element 131 and the second filter element 132 inside the hydrocyclone 1.
