Specifically, the third passage 120 extends in the direction of the partition plate along the outlet portion, that is, one end of the third passage 120 communicates with the first passage and the other end of the third passage 120 communicates with the opening.

In the present embodiment, the partition 114 is provided with an opening, and the guide portion 118 is provided through the opening.

In other embodiments, the guide 118 is located above the partition 114 along the gravity direction, the partition 114 is provided with an opening, and the third channel 120 of the guide 118 is disposed corresponding to the opening.

Therefore, the third filter 210 is arranged in the present invention, so that the third filter 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, which can ensure that the fluid flowing back into the return pipe 200 is the liquid filtered by the third filter 210, so that the solid particles can be intercepted by the third filter 210 and collected into the second chamber 140.

In detail, since the liquid lower than the upper edge of the discharge portion 180 is difficult to be discharged due to the suction effect, by reasonably arranging the bottom wall of the housing 110 such that the bottom wall of the housing 110 is inclined upward, specifically, from the discharge portion 180 toward the housing 110, the bottom wall of the housing 110 is inclined upward, so that the fluid in the second chamber 140 flows along the bottom wall of the housing 110 toward the discharge portion 180 under the action of gravity, and the fluid mixed with the solid particles is conveniently and effectively discharged out of the separator 100 through the discharge portion 180.

Example 9:

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

The present invention provides a home appliance including a separator 100, the separator 100 including a housing 110, a first filter 150, a flow guide tube 160, an outlet portion 170, and a discharge portion 180. Before the separator 100 operates, the discharge portion 180 is closed, and after the fluid mixed with the solid particles enters the separator 100 from the flow guide tube 160, a spiral swirl flow is formed along the circumferential direction of the inner wall of the second channel 154, and relatively light liquid and/or gas after the swirl separation is discharged from the separator 100 through the outlet portion 170, and relatively heavy solid particles enter the second chamber 140, and then are discharged from the separator 100 through the discharge portion 180 by opening the discharge portion 180.

Specifically, the home appliances include a dish washer, a washing machine, a clothes dryer, and the like, which are not listed herein.

In this embodiment, as shown in fig. 11, the home appliance is a dishwasher 300, and the dishwasher 300 includes a cabinet 310, a wash pump 320, a duct 330, a lower spray arm 340, a middle spray arm 350, an upper spray arm 360, a spray nozzle 370, and a chassis 380. The dishes 400 are placed in the dishwasher 300, and the dishwasher 300 circulates the washing and filtering processes as follows: the water flows out of the wash pump 320, enters the lower spray arm 340, the middle spray arm 350 and the upper spray arm 360 through the pipes 330, is sprayed on the tableware 400 through the spray nozzles 370, and the flushed contaminants fall into the chassis 380 together with the water, then enter the separator 100 together with the water, are separated and stored in the dirt collecting box of the separator 100, and the clean water flows into the wash pump 320 through the outlet portion 170 of the separator 100 to start the next cycle. Wherein the arrows indicate the flow direction of the water flow.

In the related art, the filtering mode of the dish washer is circulation filtering, and the discharged water contains a part of pollutants, so that secondary pollution can be generated to tableware. In the present application, after the separator 100 according to any one of the embodiments of the first aspect is applied to the dishwasher 300, the sewage passes through the separator 100, all contaminants are intercepted, and the discharged water is clean water, so that no secondary pollution is generated to the tableware 400, which is advantageous for improving the washing effect, reducing the washing time, and saving the water consumption.

Example 10:

the separator 100 (e.g., a cyclone separator) includes a draft tube 160, an outlet portion 170, a housing 110, a discharge portion 180, vanes 126, a first filter 150, a second filter 190.

The discharge portion 180 is closed before the cyclone is operated.

The fluid, which contains plate-like particles having a density slightly greater than the fluid, then enters the cyclone separator from the draft tube 160, and the cyclone separator begins to operate. The internal part forms strong rotational flow during operation.

On the one hand, particles smaller than the mesh size of the first filter 150 cannot pass through the first filter 150 due to the presence of the first filter 150, thereby realizing one-time full filtration; on the other hand, the first filter 150 greatly weakens the cyclone strength at the first channel, and can greatly reduce the resistance of the whole cyclone separator.

The first channel has a guide 118 (e.g., a cone) disposed therein so that the pellet may not only be thrown against the second channel 154 by centrifugal force, but also tend to move toward the second channel 154 as fluid flows down the cone from above.

After moving to the bottom in the second channel 154, the solid particles are thrown into the communication part 116 formed by the transverse partition 114 and the guide vane 126, so that the particles are prevented from depositing on the surface of the first filter 150, and the problem of blockage of the first filter 150 is solved.

Because the extending direction of the communicating portion 116 is opposite to the direction of the fluid in the first chamber, the flow velocity of the fluid in the communicating portion 116 can be reduced, and finally the disturbance of the strong rotational 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 portion 116, and the collection of the particles is realized.

The amount of particles separated into the second chamber 140 per unit time is fixed by the centrifugal force alone, and the amount of initial solid particles is increased so that the separated solid particles are not attached to the first filter 150, resulting in the blocking of the first filter 150, thereby providing the third channel 120 in the middle of the inner cone. Since the region near the center of the cyclone separator is a low pressure region, the third passage 120 is located near the low pressure region, and thus, in the cyclone separator, in addition to the flow from the flow guide 160, through the first filter 150, to the outlet 170, the flow from the second chamber 140, through the third passage 120, flows back to the inside in the direction of the outlet 170 is formed. A top-down flow is created in the first chamber to supplement the flow in the third channel 120. The fluid flows from top to bottom within the first chamber, which may carry the sheet-like particles thrown toward 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. Effectively alleviating clogging of the first filter 150.

However, after the third channel 120 is provided in the guide portion 118, the turbulence in the second chamber 140 increases, particles cannot be deposited, and part of the particles flow out of the third channel 120, so that the overall filtering efficiency of the cyclone separator is directly reduced. A second filter 190 is thus provided between the partition 114 and the bottom wall of the housing 110, the second filter 190 assisting the third passage 120 to ensure that particles can be intercepted and collected by the second chamber 140 at high reflux flow rates.

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

The cyclone stops operating and the discharge port 182 is opened, and the water and contaminant particles in the second chamber 140 are discharged by the drain pump.
