A washing machine 1 according to an embodiment of the present disclosure will be described below with reference to FIGS. 1-26.

In some specific embodiments of the present disclosure, as shown in FIGS. 1 to 6, a washing machine 1 according to an embodiment of the present disclosure includes an outer tub 100, an inner cylinder 200, and a pulsator 300.

The outer tub 100 is provided with a drain port 110 which may be provided at the bottom wall of the outer tub 100 and at the outer periphery of the bottom wall of the outer tub 100. The inner cylinder 200 is rotatably disposed in the outer tub 100, and a gap cavity 120 is defined between the inner cylinder 200 and the outer tub 100. For example, the gap cavity 120 is formed on the outer circumferential surface of the inner cylinder 200 and the inner circumferential surface of the outer tub 100. Between the outer bottom surface of the inner cylinder 200 and the inner bottom surface of the outer tub 100, the gap chamber 120 communicates with the drain port 110, and the inner cylinder 200 is provided with a chip discharge port 210, and the chip discharge port 210 spaces the inner space and the gap of the inner tube 200. The cavity 120 is in communication.

The pulsator 300 is rotatably disposed in the inner cylinder 200. The pulsator 300 defines a washing chamber 220 located above the pulsator 300 and a water receiving chamber 230 located below the pulsator 300 in the inner cylinder 200. The space in 200 is divided into two parts by the pulsator 300. The washing chamber 220 is located above the pulsator 300, and the water receiving chamber 230 below the pulsator 300, that is, the lower surface of the pulsator 300 and the inner cylinder 200 A water receiving chamber 230 is defined between the inner bottom surfaces. The water receiving chamber 230 communicates with the gap chamber 120 through the discharge port 210. The pulsator 300 is provided with a plurality of water filling holes 310 connecting the washing chamber 220 and the water receiving chamber 230. The bottom of the pulsator 300 is provided with a plurality of water inlet chambers 230 extending into the water receiving chamber 230. Drainage ribs 320. When the pulsator 300 rotates, the drain rib 320 pushes the fluid in the water receiving chamber 230 into the gap chamber 120 from the discharge port 210, and the fluid in the washing chamber 220 is filled into the water receiving chamber 230 by the water filling hole 310.

The cross-sectional area (ie, the flow area) of the single water-filling hole 310 is 10 mm ² to 20 mm ² .

The chip removal process of the washing machine 1 according to an embodiment of the present disclosure will be described below with reference to FIG.

When the washing machine 1 performs washing, the pulsator 300 rotates, the drain rib 320 rotates with the pulsator 300, and the water in the water receiving chamber 230 is centrifugally displaced by the displacement of the drain rib 320, thereby pushing the water flow into the gap through the discharge port 210. In the cavity 120, the swarf in the inner cylinder 200 is discharged to the inner cylinder 200 and the outer tub 100 with the water flow. During this process, a large negative pressure is generated in the water receiving chamber 230, and the water flow in the washing chamber 220 is caused to flow from the water filling hole 310 to the water receiving chamber 230 to supplement the reduced water in the water receiving chamber 230, thereby maintaining the entire water circulation. . After the pulsator 300 stops rotating, the swarf entering the water in the gap cavity 120 gradually settles to the bottom of the outer tub 100. When draining, the swarf in the gap cavity 120 is automatically discharged by the drain port 110 with the water flow.

For the washing machine with the water permeable hole in the side wall of the inner cylinder 200, after the pulsator 300 stops rotating, the water flow in the gap chamber 120 enters the washing chamber 220 through the water permeable hole, and since the cross-sectional area of the water permeable hole is small, With a certain ability to filter the chips, the chips do not return to the washing chamber 220 with the water flow, but gradually settle to the bottom of the outer tub 100.

The washing machine 1 according to an embodiment of the present disclosure passes the principle of time separation, that is, at the time of washing, the wire scraps pass through the discharge port 210 into the gap chamber 120 through the discharge port 210, and when the water is drained or dehydrated, the gap chamber 120 is driven by the wash water. The swarf is discharged from the drain port 110, thereby completing the automatic cleaning of the swarf, and the flow of the water flowing into the gap chamber 120 in the washing chamber 220 is increased by centrifugally squeezing the water flow, thereby greatly increasing the discharge rate of the swarf.

Moreover, since the parameter setting of the water filling hole 310 is directly related to the efficiency of whether the wire can be discharged and discharged, by defining the cross-sectional area of the water filling hole on the pulsator, that is, the cross-sectional area of the single water filling hole 310 is 10 mm ² to 20 mm ² , It is preferably 13 mm ² to 18 mm ² and may further define that the maximum span of the cross section of the water replenishing hole 310 is not more than 6 mm.

Therefore, on the one hand, the water filling hole 310 can have a sufficiently large cross-sectional area, combined with the resistance generated when the pulsator 300 rotates, and the overall water flow resistance at the water filling hole 310 can ensure that the water flow in the washing chamber 220 can smoothly enter the water. The cavity 230, thereby ensuring that the wire can smoothly enter the water receiving cavity 230;

On the other hand, it is possible to prevent the cross-sectional area of the water filling hole 310 from being excessively large, and prevent foreign matter such as coins and buttons remaining in the clothes from falling into the water filling hole 310, thereby preventing the foreign matter from entering the water receiving chamber 230 or the gap chamber 120, thereby eliminating the trouble of being difficult to take out. .

It is proved by experiments that the correspondence between the cross-sectional area of the single water-filling hole 310 and the wire discharge rate is as follows:

7mm ² , the wire discharge rate is 30%;

10mm ² , the wire discharge rate is 60%;

13mm ² , the wire discharge rate is 69%;

16mm ² , the wire discharge rate is 77%;

19mm ² , the wire discharge rate is 81%.

In some embodiments of the present disclosure, as shown in FIGS. 5 and 6, the discharge port 210 is provided at the bottom of the side wall of the inner cylinder 200 such that the discharge port 210 is located in the radial direction of the inner cylinder 200. The outer side of the cavity 230 is such that the draining water 320 is pushed into the gap cavity 120 by the discharge port 210 when the drain rib 320 rotates with the pulsator 300.

In order to further increase the wire discharge rate, the total cross-sectional area S0 of the single discharge port 210 is greater than 2500 mm ² , thereby ensuring the flow of water from the water-receiving chamber 230 into the gap chamber 120, thereby improving the chip removing effect.

It is proved by experiments that the correspondence between the cross-sectional area of the single chip discharge port 210 and the wire discharge rate is as follows:

S0=2250mm ² , the residual rate of thread waste is 46.7%;

S0=2965mm ² , the residual rate of wire waste is 35.5%;

S0=3420mm ² , the wire residue rate is 24.3%;

S0 = 3798 mm ² , and the residual rate of the thread was 19.3%.

Alternatively, in order to further increase the wire discharge rate, the discharge ports 210 may be provided in plurality and disposed along the circumferential interval of the inner cylinder 200.

Alternatively, the chip evacuation port 210 may be a grid-like through hole, as shown in FIG. 28, a lateral grid-like through hole extending in the circumferential direction of the inner cylinder 200, and then along the inner cylinder 200 as shown in FIG. The axially extending vertical grid-like through holes, of course, the discharge ports 210 may also be separate through holes as shown in FIG.

In some specific examples of the present disclosure, as shown in FIGS. 2 and 3, the gap L between the pulsator 300 and the inner cylinder 200 in the radial direction of the pulsator 300 is 2.5 mm to 3.5 mm, that is, the outer circumference of the pulsator 300 The minimum distance between the inner cylinders 200 is 2.5 mm to 3.5 mm, so that when the pulsator 300 rotates, the lint in the water receiving chamber 230 can be prevented from overflowing from the outer peripheral edge of the pulsator 300 to the washing chamber 220 to ensure The amount of wire that enters the gap cavity 120.

In some embodiments of the present disclosure, as shown in FIGS. 2 and 6, the inner barrel 200 includes a barrel 710, a barrel bottom 720, and a flange 730.

The barrel 710 has a circular cross section. The bottom 720 is mounted on the bottom of the barrel 710. The side wall of the inner tube 200 may be formed by the barrel 710 and the bottom 720, or may be formed by the barrel 710 alone. The discharge port 210 is disposed on the outer side of the bottom 720. The cylinder bottom 720 has a mounting opening 721 that penetrates in the vertical direction. The flange 730 is mounted to the bottom 720 and covers the mounting opening 721. The flange 730 and the bottom 720 together form the bottom wall of the inner cylinder 200. The drive assembly 800 can be mounted to the flange 730 and positioned below the flange 730. The drive shaft 810 of the drive assembly 800 is coupled upwardly through the flange 730 to the pulsator 300 to drive the pulsator 300 to rotate.

In some embodiments of the present disclosure, as shown in FIGS. 7 and 8, the pulsator 300 includes a wheel 330 and a plurality of water ribs 340.

The wheel 330 is rotatably disposed in the inner cylinder 200, and a plurality of drainage ribs 320 are disposed on the lower surface of the wheel 330. A plurality of water ribs 340 are disposed on the upper surface of the wheel 330. The water ribs 340 are plural and disposed along the circumferential direction of the wheel 330. Each of the water ribs 340 may extend substantially along the radial direction of the wheel 330. The faucet 340 extends into the washing chamber 220. The water replenishing hole 310 is divided into a disk surface water replenishing hole 311 provided in the wheel 330 and a rib portion water replenishing hole 312 provided in the water rib 340. The disk surface water replenishing hole 311 and the rib portion water replenishing hole 312 are provided in plurality.

By providing the disk surface water filling hole 311 in the wheel 330 and the rib water filling hole 312 in the water rib 340, the interaction with the water when the pulsator 300 rotates can be fully utilized, so that more water enters the water receiving chamber through the water filling hole 310. 230, thereby driving more swarf into the water-receiving chamber 230 to further increase the swarf discharge rate.

In some specific examples of the present disclosure, as shown in FIG. 8, the disk surface water replenishing holes 311 are distributed in a 7/10 radius region of the pulsator 300 from the center to the outer circumference of the pulsator 300, and the rib water replenishing holes 312 are distributed to the pulsator 300. From the center of the pulsator 300 to the 8/10 radius of the outer perimeter.

In other words, the outer diameter of the pulsator 300 is R, and two annular dividing lines concentrically arranged with the pulsator 300 are assumed on the pulsator 300, wherein one of the dividing lines has a radius R1 and the other dividing line has a radius of R2, R1= 7/10R, R2=8/10R, the disk surface water filling hole 311 is distributed in the boundary line with the radius R1, and the rib portion water filling hole 312 is distributed in the boundary line with the radius R2.

Therefore, when the pulsator 300 rotates, the drain rib 320 pushes the washing water in the water receiving chamber 230 to perform centrifugal movement in the radial direction of the inner cylinder 200, and limits the disc surface water replenishing hole 311 and the rib portion water replenishing hole 312 within the above range. The washing water in the water receiving chamber 230 can be prevented from returning from the disk surface water filling hole 311 and the rib water filling hole 312 to the washing chamber 220 under the displacement of the drain rib 320, thereby ensuring the amount of wire dust entering the gap cavity 120, so as to increase the wire dust discharge rate. .

Further, in the radial direction of the pulsator 300, the outermost disk surface water filling hole 311 is located at a 7/10 radius of the pulsator 300 from the center to the outer peripheral edge of the pulsator 300, and the outermost rib portion water filling hole 312 is located at the wave. The wheel 300 is from the center of the pulsator 300 to the 8/10 radius of the outer circumference. That is, the disk outer water filling hole 311 located at the outermost side is located at the boundary line of the radius R1, and the outermost rib portion water filling hole 312 is located at the boundary line of the radius R2. Therefore, in the case where the washing water in the water receiving chamber 230 is not returned from the disk surface water filling hole 311 and the rib portion water filling hole 312 to the washing chamber 220, the disk surface water filling hole 311 and the rib portion water filling hole 312 can be enlarged as much as possible. The area is increased to increase the amount of water entering the water containment chamber 230 to increase the amount of strands entering the water containment chamber 230.

Further, in order to further increase the wire discharge rate, the sum of the cross-sectional areas of the disk surface water filling holes 311 is 10% to 20% of the projected area of the pulsator 300 in the horizontal plane, and the cross-sectional area of the rib portion water filling holes 312 The sum is greater than 8% of the projected area of the pulsator 300 in the horizontal plane.

In some specific examples of the present disclosure, as shown in FIG. 7 and FIG. 8 , the water rib 340 has a first water-repellent surface 341 and a second water-repellent surface second water-repellent surface 342 , and the rib water-replenishing hole 312 is disposed on the first water-repellent surface. 341.

The first water-repellent surface 341 is inclined from the bottom to the second water-repellent surface 2, and the second water-repellent surface 342 is inclined from the bottom to the first water-repellent surface 341. The angle of inclination of the water-repellent surface 341 with respect to the horizontal plane is greater than the angle of inclination of the second water-repellent surface 342 of the second water-repellent surface with respect to the horizontal plane; and/or

The first water surface 341 is recessed toward the second water-repellent surface 2 at the center of the first water-repellent surface 341, and the second water-repellent surface 342 of the second water-repellent surface is along the second water-repellent surface. The center of the longitudinal direction protrudes away from the first water-repellent surface 341, and the curvature of the first water-repellent surface 341 is greater than the curvature of the second water-repellent surface 342 of the second water-repellent surface.

In this way, not only the holes on both sides of the water rib 340 are avoided, but the water flow directly passes through the water sling 340 and does not enter the water receiving chamber 230, and the interaction force between the first water surface 341 and the water is large, and the first water surface 341 is opposite. The water has a large upward resistance and is capable of collecting more washing water into the water-receiving chamber 230, thereby greatly increasing the wire discharge rate. In addition, the agitating effect of the water rib 340 on the water flow is improved.

In some specific examples of the present disclosure, the water rib 340, the drain rib 320, and the wheel 330 are integrally formed, and the bottom of the water rib 340 forms an upward depression, that is, it can be understood that the wheel 330 and the water rib 340 are one piece. The sheet is pressed and deformed to form an upwardly protruding water faucet 340. Of course, the description is only for the purpose of understanding the structure of the pulsator 300, and is not intended to limit the processing of the pulsator 300, and the wheel 330 is also It can be formed by other means such as injection molding.

In some specific embodiments of the present disclosure, as shown in FIGS. 9 and 10, the drainage ribs 320 are plural and radially distributed around the center of the pulsator 300, and each drainage rib 320 is along the length of the drainage rib 320. Divided into an inner edge segment 321 and an outer edge segment 322, the inner edge segment 321 is located in the 2/5 radius region of the pulsator 300 from the center of the pulsator 300 to the outer peripheral edge, and the outer edge segment 322 is located at the pulsator of the pulsator 300. The outer circumference of 300 is within a radius of 3/5 of the center.

Specifically, as shown in FIG. 10, the outer diameter of the pulsator 300 is R, and a circular boundary line concentrically arranged with the pulsator 300 is assumed on the pulsator, and the radius of the boundary line is r, r/R=2/5 The inner edge segment 321 is located within the boundary line, and the outer edge segment 322 is located between the boundary line and the outer peripheral edge of the pulsator 300.

It can be understood that the one-sided area of the inner edge section 321 and the one-side area of the outer edge section 322 refer to the area of the surface of the inner edge section 321 and the outer edge section 322 that plucks the water flow, as shown in FIG. The area of one of the inner side section 321 and the outer edge section 322, one of the two side faces orthogonal to the radial direction of the pulsator 300. Since the outer circumference of the pulsator 300 is generally tilted up, it is ensured that the outer side of the drain rib 320 has a sufficiently large water-repellent area, so that a sufficient negative pressure is generated when the pulsator 300 rotates, which not only improves the water retention. The amount of water entering the gap chamber 120 by the chamber 230 is increased, and the amount of water entering the water chamber 230 from the washing chamber 220 can be increased to increase the rate of swarf discharge.

Further, the one-side area S2 of the outer edge section 322 is not more than 3500 mm ² to prevent the drainage ribs 320 from occupying too much space in the inner cylinder 200, and the washing capacity is ensured to ensure the washing efficiency.

Optionally, each of the drainage ribs 320 has a single-sided area of 2,500 mm ² to 4,500 mm ² , that is, S1 + S2 = 2,500 mm ² to 4,500 mm ² , to enhance the displacement effect of the drainage ribs 320 on the water flow.

In some specific examples of the present disclosure, as shown in FIG. 9, the ratio of the one-side area S1 of the inner edge section 321 to the one-side area S2 of the outer edge section 322 is not more than 1/4, that is, S1/S2≤1/4 The portion of the drain rib 320 that is located on the outer side has a higher drainage capacity, and by limiting the ratio of the one-side area, the area of the inefficient area can be reduced, and the displacement water flow of the drain rib 320 can be made more efficient overall.

In some specific examples of the present disclosure, as shown in FIG. 9 and FIG. 10, in order to improve the structural strength of the pulsator 300, the bottom of the pulsator 300 is provided with a wheel bottom rib, an inner edge section 321 of the drain rib 320 and the The bottom ribs are connected.

Specifically, the wheel bottom rib includes a plurality of wheel bottom annular ribs 350 and a plurality of wheel bottom radial ribs 360.

Each of the wheel bottom annular ribs 350 extends in the circumferential direction of the pulsator 300, and a plurality of wheel bottom annular ribs 350 are coaxially disposed and located at the inner circumference of the pulsator 300. Each of the wheel bottom radial reinforcing ribs 360 is disposed between the adjacent two wheel bottom annular reinforcing ribs 350 and is respectively connected with the adjacent two wheel bottom annular reinforcing ribs 350, and the plurality of wheel bottom radial reinforcing ribs 360 are along the pulsator 300 circumferential spacing, a plurality of wheel bottom radial stiffeners 360 may be arranged in one or more turns, the specific number of turns is determined by the number of round bottom annular stiffeners 350, usually the number of turns than the number of round bottom stiffeners 350 One less. The inner edge section 321 of the drain rib 320 is connected to the outermost wheel bottom annular rib 350, and the drain rib 320 extends from the outermost wheel bottom annular rib 350 in the radial direction of the pulsator 300 to the outer peripheral edge of the pulsator 300.

Further, as shown in FIG. 9, the bottom corner of the outer end of the outer edge section 322 of the drain rib 320 is rounded to match the structure of the inner cylinder 200, and to avoid scratching other components during the rotation of the pulsator 300.

Optionally, as shown in FIG. 9, the lower edge of the inner edge section 321 is flush with the lower edge of the outer edge section 322 and is disposed in the horizontal direction, and the lower edge of the drain rib 320 is spaced apart from the inner bottom surface of the inner cylinder 200 to The uniformity of the drainage rib 320 and the water flow displacement is improved, and the drainage rib 320 is prevented from interfering with the inner cylinder 200.

In some embodiments of the present disclosure, as shown in FIGS. 11-13, the washing machine 1 further includes a one-way valve sheet 400.

The one-way valve plate 400 is disposed in the inner cylinder 200 and is used to normally close the discharge port 210. The one-way valve plate 400 opens the discharge port 210 by the fluid impact of the drain rib 320 as the pulsator 300 rotates.

Specifically, the pulsator 300 rotates, the drain rib 320 rotates with the pulsator 300, and the water in the water receiving chamber 230 is centrifugally displaced by the displacement of the drain rib 320, thereby pushing the water flow to impact the check valve 400, so that the check valve The sheet 400 opens the discharge port 210, and the wash water in the water receiving chamber 230 enters the gap chamber 120 through the discharge port 210. When the one-way valve piece 400 is not impacted by the water flow, it closes the discharge port 210 to separate the water-receiving cavity 230 and the gap cavity 120, ensures the reliability of other program operations, and can prevent the wire debris in the gap cavity 120 from being The discharge port 210 returns to the water receiving chamber 230.

Alternatively, the one-way valve sheet 400 may be made of a plastic material and formed by an injection molding process. Of course, the one-way valve sheet 400 may also be made of other materials such as metal and rubber.

In some specific examples of the present disclosure, as shown in FIG. 12, the one-way valve piece 400 is rotatably mounted to the inner cylinder 200 and often closes the discharge port 210 by its own weight.

Specifically, the one-way valve sheet 400 includes a sheet body 410 and a weighted portion 420. The sheet 410 is rotatably mounted to the inner cylinder 200. The weight portion 420 is provided on the sheet 410, and the weight portion 420 can have a weight of 35% or more of the weight of the check valve 400.

Therefore, by providing the weight increasing portion 420, the overall weight of the one-way valve piece 400 can be increased, and the one-way valve piece 400 can be opened only when the pulsator 300 is rotated to discharge the water flow, and is not easily disturbed by the disturbance of the small water flow. That is, the check valve 400 is guaranteed to be less susceptible to interference from minute water flows.

In some specific examples of the present disclosure, the body 410 is provided with a rotating shaft 430, and the inner cylinder 200 is provided with a hook 440, and the hook 440 forms a groove with an opening upward, and two ends of the rotating shaft 430 respectively enter the groove from the opening, so that Rotatingly engaging the hook 440, the one-way valve piece 400 is rotated about the rotating shaft 430 to effect the opening and closing of the discharge port 210.

For example, the rotating shaft 430 has a circular cross section, and the groove formed by the hook 440 has a semicircular cross section with the opening facing upward, and the radius of the rotating shaft 430 is at least 0.5 mm smaller than the radius of the groove to ensure the one-way valve 400. It can be smoothly assembled and rotated into the groove. The opening of the recess upwards ensures that the one-way valve flap 400 does not slip out of the recess such that the rotational contact area of the spindle 430 is primarily the lower portion of the recess.

Further, the rotating shaft 430 is disposed on the upper edge of the sheet body 410, and the weight increasing portion 420 is disposed on the surface of the sheet body 410 facing away from the chip discharge port 210 and located at the lower edge of the sheet body 410. On the one hand, the water flow displaced by the drainage ribs 320 can be facilitated to push the one-way valve piece 400 to open the discharge port 210. On the other hand, the position selection of the weight-enhancing portion 420 can move the overall center of gravity of the one-way valve plate 400 downward to ensure the one-way valve. The sheet 400 is less susceptible to interference by the minute flow of water, and the setting of the weight-increasing portion 420 does not affect the degree of fit when the check valve 400 closes the discharge port 210.

In some specific examples of the present disclosure, as shown in FIG. 12, the one-way valve sheet 400 further includes a sheet reinforcing rib 450 disposed on a surface of the sheet body 410 facing away from the discharge port 210 to improve The structural strength of the one-way valve plate 400 increases its service life.

Optionally, there are a plurality of sheet reinforcing ribs 450, each of the sheet reinforcing ribs 450 extending in the up and down direction and a plurality of sheet ribs 450 are spaced apart in the horizontal direction. It is to be understood that the up and down direction and the horizontal direction are here. This is for the case where the check valve 400 closes the discharge port 210. Of course, the arrangement of the sheet reinforcing ribs 450 is not limited thereto, and the sheet reinforcing ribs 450 may be arranged in other manners, for example, horizontally extending or the like.

In some specific examples of the present disclosure, as shown in FIGS. 11-13 and 15 , in order to arrange the one-way valve piece 400 in the inner cylinder 200 without interfering with other components, the outer surface of the inner cylinder 200 is provided. The accommodating groove 470 is located in the accommodating groove 470. For example, the accommodating groove 470 is disposed on the outer side surface of the inner cylinder 200 and penetrates the outer bottom surface of the inner cylinder 200, that is, the accommodating groove 470 is disposed at the cylinder bottom 720.

Further, as shown in FIGS. 11-13, the inner cylinder 200 is configured with a stop surface 460. The receiving groove 470 may be provided with a similar door frame structure surrounding the discharge port 210, and the stop surface 460 is formed on the door frame structure. When the check valve 400 closes the discharge port 210, the stop surface 460 stops on the inner side of the one-way valve piece 400, that is, stops on the closed side of the one-way valve piece 400 by the stop surface 460, avoiding the one-way valve piece 400 Excessive rotation to the closing side to improve the sealing effect on the discharge port 210 when the one-way valve piece 400 is closed

Further, the inner cylinder 200 is provided with a limiting structure 480 for limiting the maximum opening degree of the one-way valve piece 400 to open the discharge port 210, that is, stopping the one-way valve piece by the limiting structure 480 The open side of the 400 defines the maximum opening of the one-way valve piece 400, preventing the one-way valve piece 400 from excessively rotating toward the open side and interfering with the outer tub 100. The stopper structure 480 may be formed on the side wall of the accommodating groove 470 and protruded into the accommodating groove 470, and may be formed, for example, in the radial direction of the inner cylinder 200 of the accommodating groove 470.

Specifically, as shown in FIG. 13, when the one-way valve piece 400 is restrained to the maximum opening degree, the one-way valve piece 400 is the largest in the radial direction of the inner cylinder 200 and the central axis of the inner cylinder 200. The distance d1 is not greater than the maximum radius d2 of the inner cylinder 200. Preferably, d1 < d2. As a result, a safe collision margin can be ensured to prevent the one-way valve 400 from being excessively opened and being damaged by contact with the outer tub 100.

In some embodiments of the present disclosure, as shown in FIGS. 14-16, the washing machine 1 further includes a spray hood 500.

The spray sluice cover 500 is disposed in the inner cylinder 200 and defines a spray passage 510. The spray passage 510 has a water inlet 511 communicating with the water receiving chamber 230 and an injection hole 512 communicating with the washing chamber 220. For example, the effluent cover 500 and the inner side of the inner cylinder 200 together define a spray passage 510, and the water inlet 511 is provided at the lower end of the spray hood 500. When the pulsator 300 rotates, a part of the washing water can be squeezed from the water inlet 511 into the spray channel 510. Under the centrifugal force of the rotation of the inner cylinder 200, the water in the spray channel 510 rises upward and is sprayed from the spray hole 512. The chamber 220 is washed to enhance the washing effect.

Optionally, the sluice cover 500 and the swarf outlet 210 are disposed opposite each other in the radial direction of the inner cylinder 200.

In some specific examples of the present disclosure, as shown in FIGS. 15 and 16, the inner cylinder 200 is configured to:

When the pulsator 300 rotates in one of a clockwise direction and a counterclockwise direction, the inner cylinder 200 guides the fluid in the water receiving chamber 230 to the discharge port 210 and blocks the fluid in the water receiving chamber 230 from flowing into the water inlet 511;

When the pulsator 300 rotates in the other of the clockwise direction and the counterclockwise direction, the inner cylinder 200 guides the fluid in the water permeable chamber 230 to the water inlet 511 and blocks the fluid in the water permeable chamber 230 from flowing toward the discharge port 210.

Since the structure of the automatic removal of the wire has a certain influence on the flow of the waterfall, the resistance of the water discharged from the discharge port 210 is low, and the resistance ejected from the injection hole 512 is large, and the flow of water from the injection hole 512 needs to overcome the head resistance. And the gravity of its own, so the amount of water spray will be greatly reduced.

In an embodiment of the present disclosure, when the pulsator 300 is rotated in one direction, one of the functions of the squirting and the swarf is weakened, and the other function is reinforced, and vice versa. In this way, by adjusting the steering of the pulsator 300, the demand for rinsing the clothes by the waterfall water flow can be satisfied, and the better discharge rate of the swarf can be ensured, so that the clothes do not adhere to the swarf, thereby ensuring a high washing. degree.

Specifically, as shown in FIG. 16, the outer peripheral edge of the inner bottom surface of the inner cylinder 200 is provided with a boss 520 extending in the circumferential direction of the inner cylinder 200, and the boss 520 is disposed around the pulsator 300, and the outer circumference of the pulsator 300 is The distance L between the bosses 520 is 2.5 mm to 3.5 mm. The boss 520 is provided with a chip discharge passage 530 connecting the water receiving chamber 230 and the discharge port 210, and a spray passage 540 connecting the water receiving chamber 230 and the water inlet 511, that is, due to the arrangement of the chip removal passage 530 and the spray channel 540, The boss 520 is not a closed loop structure but an open loop structure.

Wherein, as shown in FIG. 16, a side wall of the chip discharge passage 530 is configured to guide the fluid in the water receiving chamber 230 to the chip discharge guide portion 531 of the discharge port 210, and the other side wall of the chip discharge passage 530 is configured Blocking the fluid in the water-receiving chamber 230 from flowing toward the chip choke portion 532 of the discharge port 210, the chip discharging guide portion 531 and the chip discharging choke portion 532 in the clockwise direction and the counterclockwise direction One direction is distributed in turn.

Further, one side wall of the waterfall channel 540 is configured to guide the fluid in the water receiving chamber 230 to the spray guide 541 of the water inlet 511, and the other side wall of the spray channel 540 is configured to block the water chamber 230. The fluid flows to the spray block 542 of the water inlet 511, and the spray guide 541 and the spray block 542 are sequentially distributed in the other of the clockwise direction and the counterclockwise direction.

In other words, in the circumferential direction of the inner cylinder 200, the exhaust flow blocking portion 532 - the chip discharge guide portion 531 - the spray waterfall guide portion 541 - the spray waterfall blocking portion 542 may be sequentially used.

Specifically, as shown in FIG. 16, the outer end of the chip discharging guide 531 is offset with respect to the inner end of the chip discharging guide 531 in the one of the clockwise direction and the counterclockwise direction. . The outer end of the discharge choke portion 532 is offset with respect to the inner end of the discharge choke portion 532 in the one of the clockwise direction and the counterclockwise direction.

The outer end of the spray guide portion 541 is offset with respect to the inner end of the spray guide portion 541 in the other of the clockwise direction and the counterclockwise direction. The outer end of the sluice block 542 is offset with respect to the inner end of the slugage block 542 in the other of the clockwise direction and the counterclockwise direction.

For example, in the example shown in FIG. 16, the chip discharging guide portion 531 and the chip discharging choke portion 532 are inclined in the counterclockwise direction, and the waterfall guiding portion 541 and the waterfall blocking portion 542 are inclined in the clockwise direction. .

Referring to FIG. 16 , when the pulsator 300 rotates clockwise, the water flow is difficult to enter the chip discharge passage 530 due to the blockage of the discharge block 532, and the water flow is easily guided by the flow guiding portion 541. The waterfall passage 540 is finally ejected from the injection hole 512, and most of the centrifugal water flow displaced by the pulsator 300 is converted into a waterfall water flow to enhance the washing of the laundry.

When the pulsator 300 rotates counterclockwise, the water flow is difficult to enter the sump passage 540 due to the blockage of the sluice blocking portion 542, and the water flow is guided by the swarf guiding portion 531, so that it is easy to enter the discharge port 210, thereby facilitating the flow. The discharge of wire scraps.

Alternatively, the chip discharge guide portion 531, the chip discharge choke portion 532, the spray waterfall guide portion 541, and the spray block flow blocking portion 542 may each be configured as a straight slope. The chip discharge guide portion 531, the chip discharge choke portion 532, the spray waterfall guide portion 541, and the spray block flow blocking portion 542 may each be configured in an arc shape, specifically, in the cross section of the inner cylinder 200, the chip discharge The flow guiding portion 531 has an arc shape protruding in the direction of the chip discharging passage 530, and the chip discharging choke portion 532 is curved in a direction away from the chip discharging passage 530, and the spray guiding portion 541 is directed toward the spray channel 540. The direction of the arc is convex, and the sluice block 542 is curved in a direction that is recessed away from the dam channel 540.

In other specific embodiments of the present disclosure, as shown in FIG. 17 and FIG. 18, the inner cylinder 200 is provided with a water permeable hole. Specifically, the side wall of the inner cylinder 200 is provided with a large water permeable hole 240 and a small water permeable hole 250, which is large. The smallest cross-sectional area of the water permeable hole 240 is larger than the minimum cross-sectional area of the small water permeable hole 250, that is, the flow area of the large water permeable hole 240 is larger than the flow area of the small water permeable hole 250, and the large water permeable hole 240 is located at the upper part of the inner tube 200, and the small water permeable hole 250 is located at a lower portion of the inner cylinder 200. It should be understood here that the upper and lower portions of the inner cylinder 200 may be bounded by a center boundary line in the height direction of the inner cylinder 200, and the boundary line portion is an upper portion of the inner cylinder 200, and the lower portion of the boundary line is the inner cylinder 200. In the lower portion, the boundary line may be finely adjusted in the up and down direction instead of being completely at the center, and as long as the entire inner cylinder 200 is formed, a structure in which the upper water permeable hole is large and the lower water permeable hole is small may be formed.

Therefore, a structure in which a large water permeable hole 240 is disposed in the upper portion of the inner cylinder 200 and a small water permeable hole 250 is disposed in the lower portion ensures that the water flowing between the coils enters the gap chamber 120 through the discharge port 210, and the swarf is subjected to the resistance of the small permeable hole 250. It is not easy to return to the inner cylinder 200, thereby depositing or suspending in the gap chamber 120, and automatically discharging with the water flow when draining. At the same time, the large water permeable hole 240 in the upper portion of the inner cylinder 200 can ensure better dehydration efficiency due to the centrifugal climbing action during dehydration.

Specifically, as shown in FIG. 17, the 1/2 to 3/5 of the overall height of the inner cylinder 200 is a boundary line, the large water permeable hole 240 is located above the boundary line, and the small water permeable hole 250 is located below the boundary line. Specifically, the overall height of the inner cylinder 200 is H, and the height of the boundary line from the bottom of the inner cylinder 200 is h, h/H=1/2 to 3/5, and the large water permeable hole 240 is located above the boundary line and is small. The water permeable hole 250 is located below the boundary line, thereby ensuring both the wire discharge rate and the dewatering efficiency.

Optionally, the large water permeable aperture 240 has a minimum cross-sectional area of 3 mm ² to 9.5 mm ² and the small water permeable aperture 250 has a minimum cross-sectional area of 0.1 mm ² to 3 mm ² .

And a plurality of rows are arranged along the circumferential interval of the inner cylinder 200.

In some embodiments of the present disclosure, as shown in FIGS. 19-21, the outer bottom surface of the inner cylinder 200 is provided with a plurality of drainage wings 600, that is, the bottom of the bottom 720 is provided with a drainage wing 600, and a plurality of drainage wings 600 are provided with the inner cylinder. When the 200 rotates, a pressure difference is formed in the gap chamber 120, so that the fluid in the water receiving chamber 230 enters the gap chamber 120 from the discharge port 210.

Specifically, during the washing process, the inner cylinder 200 is controlled to rotate at a certain speed by the program, and the drainage fin 600 rotates with the inner cylinder 200. Due to the action of the drainage fin 600, the water level in the gap chamber 120 is greatly increased, so that the gap chamber is increased. The bottom portion of the 120 forms a relatively low pressure region, which causes the water chamber 230 to form a sufficient pressure gradient with the relatively low pressure region, and the water flow in the water receiving chamber 230 is discharged into the gap chamber 120 through the discharge port 210, while the washing chamber 220 The water in the water is filled into the water receiving chamber 230 by the disk surface water filling hole 311 and the rib portion water filling hole 312. After the inner cylinder 200 stops rotating, the water flow in the gap chamber 120 returns to the washing chamber 220. At this time, the thread is blocked by the water permeable hole of the inner cylinder 200 and is difficult to enter the washing chamber 220, thereby temporarily remaining in the gap chamber 120. Discharged with water when draining.

Therefore, the bottom drainage fin 600 of the inner cylinder 200 is used to dial water to form a relatively low pressure zone, which improves the chip removal efficiency and the chip discharge amount, and the drainage wing 600 is more flexible in setting, and the optional space is larger, and the capacity can be greatly improved. The water flow displacement rate of the water chamber 230 and the gap chamber 120 increases the wire discharge rate.

It will be understood by those skilled in the art that the manner of the drainage fins 600 and the manner of the drain ribs 320 may be alternatively or simultaneously set.

Further, as shown in FIGS. 19 to 21, the drainage fins 600 are plural and are disposed at the outer peripheral edge of the outer bottom surface of the inner cylinder 200 at intervals in the circumferential direction of the inner cylinder 200. The drain fin 600 is further away from the center of the inner cylinder 200, and the centrifugal force generated is greater, and by providing a larger number of drain fins 600, the dialed water flow can be increased.

Optionally, each of the drainage fins 600 has a single side area of 400 mm ² to 1200 mm ² , that is, the water discharge area of the drainage wing 600 is 400 mm ² to 1200 mm ² , and the sum of the single side areas of the plurality of drainage wings 600 is 12000 mm ² ～ 36000mm ² , thereby ensuring better chip removal rate and the strength of a single drainage wing 600.

In some specific examples of the present disclosure, as shown in FIGS. 20 and 21, the inner end of the drain fin 600 is offset from the inner end of the drain fin 600 in the circumferential direction of the inner cylinder 200 in the cross section of the inner cylinder 200. That is, the drain fin 600 is disposed obliquely with respect to the radial direction of the inner cylinder 200.

Optionally, as shown in FIG. 20, in the cross section of the inner cylinder 200, the drainage wing 600 is linear, and the angle α between the drainage wing 600 and the radial line of the inner end of the drainage wing 600 is -60°. ～60°, that is, the angle α between the line connecting the inner end of the drainage fin 600 and the center of the inner cylinder 200 and the longitudinal direction of the drainage fin 600 is -60° to 60°. Wherein, when α is a positive value, the inclination direction of the drainage wing 600 coincides with the rotation direction of the inner cylinder 200, and the power consumption is low at this time; when α is a negative value, the inclination direction of the drainage wing 600 and the rotation direction of the inner cylinder 200 On the contrary, the wire discharge rate is higher at this time.

Alternatively, as shown in FIG. 21, in the cross section of the inner cylinder 200, the drainage fin 600 is curved, and the angle β between the tangent to the inner end of the drainage fin 600 and the tangent to the outer end of the drainage fin 600 is 60°. ～120°, the centrifugal water flow that can be generated is large, and the power consumption is small.

In some specific examples of the present disclosure, as shown in FIGS. 19-21, in order to increase the structural strength of the inner cylinder 200, the outer bottom surface of the inner cylinder 200 (ie, the bottom of the cylinder bottom 720) is provided with a bottom reinforcement rib, a drainage wing 600 is connected to the bottom reinforcement rib.

Specifically, the bottom reinforcement rib includes a plurality of bottom annular ribs 610 and a plurality of bottom radial ribs 620.

Each of the bottom radial ribs 620 is disposed between the adjacent two bottom annular ribs 610 and is respectively connected to the adjacent two bottom annular ribs 610. The plurality of bottom-bottom radial reinforcing ribs 620 are disposed along the circumferential direction of the inner cylinder 200, and the plurality of bottom-bottom radial reinforcing ribs 620 may be arranged in one or more turns, and the specific number of turns is determined by the number of the annular reinforcing ribs 610 at the bottom of the cylinder. Typically, the number of turns is one less than the number of annular ribs 610 at the bottom of the barrel. The drain wing 600 is coupled to the outermost bottom annular rib 610, and the drain wing 600 extends from the outermost bottom annular rib 610 in the radial direction of the inner cylinder 200 to the outer periphery of the inner cylinder 200.

In some embodiments of the present disclosure, as shown in FIGS. 22-24, the inner barrel 200 includes a barrel 710, a barrel bottom 720, and a flange 730.

The flange 730 is The non-porous closed structure, that is, the water supply hole is not provided on the flange 730. In this way, the circulation of the water flow can be completely blocked, so that the wire chips in the gap cavity 120 are not returned to the washing chamber 220 through the flange 730, thereby improving the wire removal rate, and at the same time, the flange 730 without the water hole can be lifted. The inner cylinder 200 has anti-eccentricity and simple structure, and the stamping die process is simple, the process is small, and the production process complexity and production cost are reduced.

Specifically, the existing flange opening water hole is required to balance the drainage and the rigidity of the inner cylinder. The distribution of the opening on the flange is wide, and the area of the single opening is small, such as the application of the existing flange. The washing machine 1 in the present disclosure, due to the viscous resistance of water, causes the wire scraps in the space below the pulsator to easily remain in the upper part of the flange. After multiple washings, it is easy to mix a large amount of the flange and the bottom of the cylinder. The wire scraping, polluting the body, and at the same time, after the flange is opened, the center of the bottom cavity between the outer tub and the inner cylinder communicates with the central area of the space below the pulsator. When the pulsator rotates and washes the laundry, the water in the back cavity of the pulsator will The centrifugal force acts on the circumference to form a negative pressure zone in the central region, and the water flow in the central region between the outer tub and the inner cylinder and the water flow in the washing chamber are subjected to the pressure difference gravitational force respectively upward and downward toward the pulsator The central space of the lower space flows, and the upward hydration method will cause some of the water flowing into the space between the outer tub and the inner cylinder to return to the space below the pulsator, and enter the space due to the pressure surge when the pulsator is stopped. Hydrating in the washing chamber while facing upwards The flow rate will greatly reduce the downward hydration flow and reduce the discharge rate of the wire in the washing chamber.

According to the flange 730 of the washing machine 1 of the embodiment of the present disclosure, the arrangement of the water-free hole can prevent the wire from entering the water-receiving cavity 230 from the through-hole thereof, and the hydrating water can only be hydrated by the pulsator 300 when the pulsator 300 rotates. The hole 310 replenishes the water chamber 230 to maintain the pressure balance, and the negative pressure formed after the water volume in the washing chamber is reduced is supplemented by the water flow of the gap chamber 110 through the inner tube permeable hole, and the swarf which can be returned to the washing chamber 220 is only 7~. About 8%, thereby effectively increasing the discharge rate of the wire, greatly reducing the residual rate of the wire in the washing chamber 220 and the water chamber 230. In addition, the lint and dirt do not easily remain on the flange 730.

Moreover, the existing flanges for opening the water holes will reduce the rigidity of the inner cylinder, especially the large opening holes in the concentrated area have a greater influence on the rigidity of the inner cylinder, which may cause the eccentricity when the laundry is washed and dehydrated, and the impact tube The risk is greatly increased. Therefore, the opening area on the flange is not required to be too large, and the opening on the flange is required to be widely distributed. However, in order to balance the drainage speed, the opening area on the flange cannot be too small. This causes the existing flange opening area to be set to an intermediate value, which causes the drainage speed and the cylinder eccentric impact indicator to fail to reach an optimized value.

According to the flange 730 of the washing machine 1 according to the embodiment of the present disclosure, the flange 730 without the water hole can greatly reduce the risk of the collision tube, improve the washing safety performance, and at the same time, rely on the gravity of the water flow when draining, the one-way valve piece After the draining port 210 is opened, the drainage operation is performed, and the opening area of the chip discharging port 210 can be set large, which is convenient for rapid drainage and improves the drainage speed.

The outer edge region 760 is further provided with a plurality of limiting holes 763, and the limiting holes 763 cooperate with the protrusions 722 of the bottom 720 (as shown in FIG. 21).

The middle edge region 750 is provided with a rotating shaft hole 741 through which the driving shaft 810 of the pulsator 300 passes, and the central portion 740 is further provided with a plurality of screw holes 742 for fixing the driving assembly 800 of the pulsator 300, and the plurality of screw holes 742 surround the rotating shaft The holes 741 are spaced apart.

The transition ring 770, which is inclined at a horizontal plane, is connected, and the bottom 720 is configured with a bevel that cooperates with the transition ring 770. Thereby, the tightness of the combination of the flange 730 and the bottom 720 can be improved, and the space under the inner cylinder 200 can be saved to facilitate the mounting of the drive assembly 800.

Further, the transition ring 770 is configured as a non-porous structure to prevent wash water in the gap cavity 120 and the inclusions therein from being returned to the wash chamber 220 by the flange 730.

Optionally, to avoid stress concentration and scratching other components, the transition ring 770 and the middle edge region 750 and between the transition ring 770 and the outer edge region 760 are respectively rounded.

In some specific examples of the present disclosure, as shown in FIGS. 23 and 24, the outer contours of the mounting opening 721 and the middle edge region 750 are circularly shaped, and the outer contour of the outer peripheral region 760 is rectangular, and the outer peripheral region is The inner contour of the 760 has a circular shape that is adapted to the outer contour shape of the middle edge region 750, thereby facilitating the covering of the mounting opening 721, reducing the resistance to water flow, and facilitating the stability of the mounting of the flange 730 and the inner cylinder 200.

Wherein, the flange 730 is a single piece, that is, the central zone 740, the middle edge zone 750, the outer edge zone 760 and the transition ring 770 are integrally formed to improve the structural strength of the flange 730, simplify the production process of the flange 730 and cost.

In some embodiments of the present disclosure, as shown in FIGS. 25 and 26, the inner barrel 200 includes a barrel 710, a barrel bottom 720, and a flange 730.

The barrel 710 has a circular cross section. The bottom 720 is mounted to the bottom of the barrel 710, and the bottom 720 has a mounting opening 721. The flange 730 is integrally formed with the base 720 by being inserted into the bottom 720, and the flange 730 covers the mounting opening 721. Thereby, the joint gap between the flange 730 and the bottom 720 can be eliminated, and the swarf can be prevented from being caught in the gap between the flange 730 and the bottom 720. On the one hand, the discharge of the wire is facilitated, and on the other hand, it can be ensured. The laundry environment of the washing machine 1 is clean.

Specifically, the flange 730 is a metal piece, the bottom 720 is a plastic part, and the flange 730 is inserted into the base 720 by injection molding. With a mixture of different materials, the cost is greatly reduced compared to the one-piece inner cylinder bottom made entirely of metal.

In some specific examples of the present disclosure, as shown in FIGS. 25 and 26, the flange 730 is divided into a central zone 740, a middle edge zone 750, and an outer edge zone from the inside to the outside in the radial direction of the flange 730 (in In the present embodiment, due to the relationship of the angle of the drawing, the outer edge region has been embedded in the bottom 720, so the outer edge region is not shown in the drawing, and the flange 730 is inserted into the bottom 720, the middle edge region 750 and the center through the outer edge region. The zone 740 collectively covers the mounting opening 721, the middle edge zone 750 is configured as a non-porous structure, and the central zone 740 is used to mount the drive assembly 800 of the pulsator 300. In other words, the flange 730 is not only provided for the installation of the required holes, such as the flange 730 and the hole provided by the drive assembly 800. The flange 730 is a non-porous closed mechanism, that is, the flange 730 is not Set the water hole.

Thus, the flange 730 and the bottom 720 are integrated to form a closed inner and outer space. When the pulsator 300 rotates, the water with the swarf flows from the washing chamber 220 into the gap chamber 120 from the discharge port 210, and the water flow can only be washed from the washing chamber 220. The chamber 220 moves downwardly to the water containing chamber 230 to supplement the reduced water flow of the water containing chamber 230. When the pulsator 300 is stopped, the discharge port 210 is closed by the one-way valve piece 400, and the water flow in the gap cavity 120 can only return to the inner cylinder 200 through the water permeable hole, thereby functioning to filter the wire.

Moreover, since the existing flange is provided with a water-passing hole, in order to ensure the overall structural strength, the flange needs to be thickened or provided with a rugged structure to increase the strength, resulting in a higher flange height and a larger space. However, according to the flange 730 of the washing machine 1 according to the embodiment of the present disclosure, since the flange 730 has a water-free hole structure, it is not necessary to provide a thick and uneven structure, thereby reducing the space occupied. For example, the flange 730 can be a flat plate, and its maximum height (ie, thickness) is 5 mm to 10 mm, which is much smaller than the thickness of the existing flange of about 32 mm, which can save a lot of space.

In some specific examples of the present disclosure, the central zone 740 is provided with a spindle hole 741 through which the drive shaft 810 of the pulsator 300 passes, and the central zone 740 is further provided with a plurality of screw holes 742 for securing the drive assembly 800 of the pulsator 300. A plurality of screw holes 742 are spaced apart around the shaft hole 741.

In some embodiments of the present disclosure, as shown in FIGS. 25 and 26, the mounting opening 721 and the outer contour of the flange 730 are rounded in shape, thereby facilitating the covering of the mounting opening 721 and reducing the flow of water. The resistance also facilitates the embedding of the flange 730 and the inner cylinder 200.

The flange 730 is a single piece, that is, the central zone 740, the middle edge zone 750 and the outer edge zone 760 are integrally formed to improve the structural strength of the flange 730 and simplify the production process and cost of the flange 730.
