In detail, the amount of solid particles separated into the second chamber 140 per unit time is fixed by simply relying on centrifugal force. If the amount of solid particles in the fluid is increased, the separated solid particles (e.g., contaminants) may not be able to attach to the first filter element 150, resulting in clogging of the first filter element 150. Therefore, by properly configuring the separator 100, the separator 100 includes the return pipe 200, one end of the return pipe 200 is connected to the housing 110, one end of the return pipe 200 is communicated with the second chamber 140, the other end of the return pipe 200 is communicated with the outlet 170, and one end of the return pipe 200 is located in the low pressure area, so that, inside the separator 100, besides the flow from the guide pipe 160 to the outlet 170 through the second passage 154 and the first passage, the flow from the second chamber 140 to the outlet 170 through the return pipe 200 is also formed. That is, more fluid is introduced into the first chamber from the top to the bottom of the return pipe 200, so that more fluid can flow into the flow guide pipe 160. The fluid flows from top to bottom in the first chamber, and the solid particles thrown to the wall of the first chamber flow downward into the second chamber 140, so that the amount of the solid particles separated into the second chamber 140 per unit time is increased, and the blockage of the first filter 150 is effectively relieved.

Further, as shown in fig. 9, the separator 100 further includes a third filter member 210, the third filter member 210 is located in the second chamber 140, the third filter member 210 is provided with a fifth path, one end of the fifth path is connected to the partition plate 114, the other end of the fifth path is connected to the bottom wall of the second chamber 140, and one end of the return pipe 200 is connected to the fifth path.

Therefore, the third filter element 210 is disposed such that the third filter element 210 includes a fifth channel, one end of the fifth channel is connected to the partition 114, and the other end of the fifth channel is connected to the bottom wall of the second chamber 140, so that the fluid flowing back to the return pipe 200 is the liquid filtered by the third filter element 210, and the solid particles can be intercepted by the third filter element 210 and then collected in the second chamber 140.

Specifically, the third filter member 210 includes a plurality of filter portions including at least one of filter holes and filter openings, and the plurality of filter portions are uniformly arranged to filter solid particles in the fluid flowing through the third filter member 210 through the filter portions.

This arrangement provides for the vanes 126 to have the effect of directing the fluid flow such that the fluid within the second passage 154 may be effectively channeled into the second chamber 140.

Meanwhile, by reasonably arranging the arrangement structure of the guide vanes 126, the extension direction of the guide pipe 160 is different from the direction of the fluid in the second passage 154, so that the flow velocity of the fluid in the communicating part 116 can be reduced to weaken the disturbance of the strong rotational flow in the first chamber to the fluid in the second chamber 140, so that the solid particles can effectively flow into the second chamber 140 from the communicating part 116 to be deposited in the second chamber 140, and the collection of the solid particles is realized.

Specifically, there is a gap between the edge of the diaphragm 114 and the wall of the second chamber 140, and the vanes 126 extend beyond the edge of the diaphragm 114.

Further, the first chamber is located above the second chamber 140 along the first direction, the bottom wall of the housing 110 is inclined upward from the discharging portion 180 toward the housing 110, and the first direction is a gravity direction.

In detail, due to the suction effect, the liquid below the upper edge of the discharging portion 180 is difficult to be discharged, and therefore, by reasonably setting the structure of the bottom wall of the casing 110, the bottom wall of the casing 110 is inclined upward, specifically, from the discharging portion 180 to the direction of the casing 110, the bottom wall of the casing 110 is inclined upward, so that the fluid in the second chamber 140 flows to the discharging portion 180 along the bottom wall of the casing 110 under the action of gravity, which facilitates the fluid mixed with the solid particles to be effectively discharged out of the separator 100 through the discharging portion 180.

Specifically, as shown in fig. 3 and 9, the bottom wall of the housing 110 has an angle C with the horizontal plane that satisfies: c is more than 0 degree and less than 90 degrees.

Example 9:

an embodiment of the second aspect of the present invention proposes a home appliance, comprising: the separator of any embodiment of the first aspect.

The household appliance provided by the present invention comprises a separator 100, the separator 100 comprising a housing 110, a first filter 150, a flow conduit 160, an outlet section 170 and a discharge section 180. Before the separator 100 is operated, the discharge portion 180 is closed, and then the fluid mixed with the solid particles enters the separator 100 from the flow guide tube 160, and flows along the circumferential direction of the inner wall of the second passage 154 to form a spiral cyclone, the relatively light liquid and/or gas after cyclone separation is discharged out of the separator 100 through the outlet portion 170, and the relatively heavy solid particles enter the second chamber 140, and then are discharged out of the separator 100 through the discharge portion 180 by opening the discharge portion 180.

Further, due to the action of the first filter element 150, the solid particles flow from the top to the bottom of the second channel 154 and are thrown into the second chamber 140 by centrifugal force, so that the solid particles are prevented from depositing on the outer wall of the first filter element 150, the first filter element 150 is not blocked, and the gas-liquid-solid separation efficiency of the separator 100 is ensured.

Specifically, the household appliances include a dishwasher, a washing machine, a dryer, and the like, which are not listed here.

In the present embodiment, as shown in fig. 11, the household appliance is a dishwasher 300, the dishwasher 300 comprising a cabinet 310, a washing pump 320, a pipe 330, a lower spray arm 340, a middle spray arm 350, an upper spray arm 360, a spout 370, a chassis 380. The tableware 400 is placed in the dishwasher 300, and the dishwasher 300 circulates the washing and filtering processes as follows: the water flows out of the washing pump 320, and enters the lower spray arm 340, the middle spray arm 350 and the upper spray arm 360 through the pipe 330, and then is sprayed on the tableware 400 through the spraying nozzle 370, the flushed contaminants fall into the bottom plate 380 together with the water, and then enter the separator 100 together with the water, the contaminants are separated and stored in the dirt collecting box of the separator 100, and the clean water flows into the washing pump 320 through the outlet 170 of the separator 100, and the next cycle is started. Wherein the arrows indicate the flow direction of the water flow.

In the related art, the filtering method of the dish washer is a circulation filtering method, and the effluent water contains a part of pollutants and can cause secondary pollution to the tableware. After the separator 100 of any embodiment of the first aspect is applied to the dishwasher 300, all pollutants are intercepted when sewage passes through the separator 100, and the effluent water is clean water, so that secondary pollution to the tableware 400 is avoided, the washing effect is improved, the washing time is reduced, and the water consumption is saved.

Example 10:

the separator 100 (e.g., a cyclonic fluid separator) includes a draft tube 160, an outlet portion 170, a housing 110, a discharge portion 180, a guide vane 126, a first filter pack 150, and a second filter pack 190.

Before the cyclone separator is operated, the discharge section 180 is closed.

The fluid, which then contains plate-like particles having a density slightly greater than the fluid, enters the cyclone separator from the draft tube 160, and the cyclone separator begins to operate. When running, strong rotational flow is formed inside the reactor.

Due to the first filter member 150, on the one hand, particles smaller than the mesh size of the first filter member 150 cannot pass through the first filter member 150, thereby realizing a full filtration; on the other hand, the first filter 150 greatly weakens the strength of the swirling flow at the first passage, and can greatly reduce the resistance of the entire cyclone separator.

A guide 118 (e.g., a cone) is provided in the first passage so that the sheet-like particles are not only thrown by centrifugal force toward the second passage 154, but also tend to move toward the second passage 154 as the fluid flows upward and downward within the cone.

After moving to the bottom in the second channel 154, the solid particles are thrown into the communication portion 116 formed by the transverse partition plate 114 and the guide vane 126, so as to avoid the particles from depositing on the surface of the first filter element 150, and solve the problem of blockage of the first filter element 150.

Because the extending direction of the communicating part 116 is opposite to the direction of the fluid in the first chamber, the flow velocity of the fluid in the communicating part 116 can be reduced, and finally the disturbance of the strong swirling flow of the fluid to the fluid in the second chamber 140 is weakened, so that the solid particles can be deposited in the second chamber 140 after entering the second chamber 140 from the communicating part 116, and the collection of the particles is realized.

The amount of particles separated into the second chamber 140 per unit time is constant by the centrifugal force alone, increasing the initial amount of solid particles that may not reach the first filter 150 to be attached, resulting in the first filter 150 being clogged, and thus the third channel 120 is provided in the middle of the inner cone. Since the region near the center of the cyclone is a low-pressure region, near which the third channel 120 is located, a flow from the flow guide tube 160, through the first filter 150, to the outlet section 170, and a return flow from the second chamber 140, through the third channel 120, to the interior in the direction of the outlet section 170 are formed in the cyclone. A top-down flow is established in the first chamber to supplement the flow in the third channel 120. The fluid flowing from the top down in the first chamber may carry the plate-like particles thrown towards the second channel 154 down into the second chamber 140, thereby increasing the amount of solid particles separated into the second chamber 140 per unit time. Clogging of the first filter member 150 is effectively alleviated.

However, when the guide portion 118 is disposed in the third channel 120, the turbulence in the second chamber 140 increases, particles cannot be deposited, and a part of the particles flows out from the third channel 120, which directly reduces the overall filtering efficiency of the cyclone separator. Thus, the second filter pack 190 is disposed between the partition 114 and the bottom wall of the housing 110, and the second filter pack 190 may assist the third passage 120 to ensure that particles may be intercepted and collected by the second chamber 140 under high return flow rates.

The bottom wall of the housing 110 is at an angle C (0 ° < C <90 °) to the horizontal. Because water below the upper edge of the discharge opening 182 is difficult to remove due to suction, the bottom wall of the housing 110 is designed to be sloped so that as much fluid and contaminants as possible are discharged to complete particle collection.

The cyclonic separator is deactivated and the discharge opening 182 is opened to allow the water and contaminant particles in the second chamber 140 to be discharged by the drain pump.
