Description

Washing machine {WASHING MACHINE}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine, and more particularly, to a washing machine for generating bubbles and supplying the generated bubbles to a tub.

Generally, a washing machine performs washing of clothes by friction between water and laundry by rotation of a pulsator installed inside the washing tub. Specifically, a large number of perforations are formed in the outer circumferential surface of the washing tub located inside the tub, so that the water introduced into the tub flows into the tub, or water in the tub is discharged to the tub. That is, during washing, rinsing, and dewatering, the water in the tub is discharged to the outside of the tub through the drain line provided at the bottom of the tub.

Accordingly, the laundry contained in the washing tub is washed by the rotation of the washing water stored in the tub and the washing tub by the rotation of the pulsator, and by the contact of the laundry.

However, when the detergent or foreign matter remaining on the surface of the laundry remains in the laundry, there is a problem that the wearer repeatedly wears such clothes to cause skin irritation such as atopy.

In order to prevent this, a variety of techniques for supplying the washing water to the surface in a minute size have been applied. However, there is a problem that a separate device such as a pump for generating washing water in a minute size is installed. In such a case, noise due to the driving of the pump and maintenance work due to repetitive use thereof are difficult.

Thus, the embodiment is not limited to any particular form of the depicted area, but includes modifications of the form, for example, by manufacture.

Hereinafter, a washing machine 101 according to an embodiment of the present invention will be described with reference to FIGS. 1, 2, and 4 to 6. FIG.

1, a washing machine according to an embodiment of the present invention includes a housing 100, a tub 200, a drain line 210, a drain valve 500, a dissolving unit 300, (400).

The housing 100 forms an appearance of the washing machine 101. In addition, the housing 100 has a space therein in which the tub 200, the dissolving unit 300, and the bubble generating units 400 can be disposed.

The tub 200 is disposed inside the housing 100. Specifically, the tub 200 is a water tank in which wash water is stored. And, the tub 200 can be supported inside the housing 100 by a suspension device, as shown in Fig.

The drain line 210 is connected to the lower portion of the tub 200. Specifically, the drain line 210 is connected to a lower portion of the tub 200 where the washing water is stored, and is guided to be drained to the outside of the tub 200 where the washing water used for washing is stored.

The drain valve 500 is disposed on the drain line 210, as shown in FIG. In addition, the drain valve 500 can selectively partition the internal flow path of the drain line 210. Specifically, the drain valve 500 is operated by the control unit to selectively partition the flow path of the drain line 210.

That is, when the wash water is to be discharged to the outside of the tub 200, the controller may control the drain valve 500 to open the internal flow path of the drain line 210. The drain valve 500 divides the internal flow path of the drain line 210 and connects the drain valve 500 and one side of the drain valve 500 to the tub 200. In the case where the washing water is to be stored in the tub 200, And the washing water supplied into the tub 200 can be stored.

For example, the drain valve 500 is driven by a separate driving unit, and the internal flow path of the drain valve 500 can be selectively closed.

Air is stored inside the dissolving unit 300. In addition, a dissolution inlet 331 is formed at one side of the dissolution part 300 so that water is supplied from the outside to the inside of the dissolution part 300. A dissolution guide hole 311 is formed on the other side of the dissolving unit 300 to guide the air stored in the water introduced from the dissolving inlet 331 to dissolve and be discharged to the outside of the dissolving unit 300.

Water dissolved in air flows into the bubble generator 400 through the dissolution guide 311. [ In addition, the bubble generator 400 generates a bubble with the water in which the introduced air is dissolved. The bubble generator 400 supplies the generated bubbles to the drain line 210 adjacent to the tub 200 among the drain lines 210 partitioned by the drain valve 500. The bubbles generated in the bubble generator 400 may be supplied to the upper drain line 210 between the drain valve 500 and the tub 200. [ That is, the bubbles generated in the bubble generator 400 may be supplied to the lower portion of the tub 200 along the upper drain line 210.

The bubbles are supplied to the lower part of the tub 200 and one side of the drain valve 500 and the inner circumferential surface of the tub 200 can form one area, 200, respectively.

In addition, the dissolving unit 300 of the washing machine 101 according to an embodiment of the present invention may further include a dissolving drain hole 312, as shown in FIG. The drain port 312 may communicate with the drain line 210 relatively distant from the tub 200 among the drain lines 210 defined by the drain valve 500.

Specifically, the dissolution drain port 312 may be formed on the other side of the dissolution section 300. The dissolution drain hole 312 may be formed apart from the dissolution guide hole 311.

The drain port 312 may communicate with the lower drain line 210 disposed below the upper drain line 210 between the drain valve 500 and the tub 200. Therefore, the water discharged through the dissolution drain port 312 can be discharged to the outside of the tub 200 through the drain line 210 regardless of whether the drain valve 500 is opened or closed.

The dissolution guide 311 formed in the dissolution part 300 of the washing machine 101 according to an embodiment of the present invention may be disposed relatively above the dissolution drainage port 312. [ Specifically, the dissolution guide 311 may be formed on the upper side of the dissolution drain port 312 along the longitudinal direction of the dissolution part 300.

The dissolving unit 300 may include an outer body 310, a valve receiving protrusion 351, an inner body 320, and a dissolving cap 330, as shown in FIG.

The outer body 310 may be open at one side and hollow inside. For example, the outer body 310 may be formed in a hollow shape having a lower hemispherical shape and a top open cross-section having a "U" shape.

Specifically, one side of the outer body 310 is formed in an open shape, and a drain hole 315 is formed in the other side of the outer body 310. That is, the outer body 310 has a U-shaped cross section and a space can be formed to store the fluid therein. Therefore, one side of the outer body 310 is completely opened, and the other side of the outer body 310 is formed in a hemispherical shape, and a drain hole 315 relatively smaller than the opened side can be formed. For example, the drain hole 315 may be formed on the other lowermost surface of the external body 310.

The valve receiving protrusion 351 may be formed to surround the drain hole 315. In addition, the valve receiving protrusion 351 may protrude outward along the longitudinal direction of the outer body 310 at one side of the outer body 310. Specifically, the valve receiving protrusion 351 may protrude from the other side of the outer body 310 so as to surround the drain hole 315. That is, a hollow portion communicating with the drain hole 315 may be formed inside the valve receiving protrusion 351.

The inner body 320 may have one side opened in the same manner as the outer body 310 and the other side may be formed in a hemispherical shape. Also, the inner body 320 may be disposed inside the outer body 310. The outer circumferential surface of the inner body 320 may be spaced apart from the outer circumferential surface of the inner body 320 to form a dissolving flow path. Specifically, one side of the inner body 320 may be supported on one side of the outer body 310.

That is, one side of the inner body 320 is supported on one side of the outer body 310, and the outer circumferential surface of the inner body 320 is spaced apart from the inner circumferential surface of the outer body 310 to form a dissolution path.

The dissolving cap 330 may be coupled to one side of the outer body 310. Specifically, the dissolving cap 330 may be formed in an approximately hemispherical shape to cover an open side of the outer body 310. Accordingly, the hemispherical shape of the dissolving cap 330 and the hemispherical shape of the lower portion of the outer body 310 can effectively store air inside the dissolving unit 300. The dissolution cap (330) may be formed with a dissolution inlet (331). The dissolution inlet 331 may guide the water supplied from the outside to be supplied to the inside of the inner body 320.

The inner body 320 may have a porous portion 321 formed on the inner surface thereof. The repletion 321 can guide at least a part of the water introduced into the interior of the inner body 320 through the dissolution inflow port 331 to collide with the water currently flowing through the dissolution inflow port 331 and to be moved to the dissolution path . The porous body 321 may be formed on one side of the inner body 320 or on one side of the outer surface of the inner body 320. Specifically, the porous portion 321 may be formed in one region of the inner body 320, which is relatively adjacent to the dissolution inlet 331. For example, the plurality of holes 321 may be formed along the circumferential direction of the inner body 320 with respect to each other. That is, the porous portion 321 may be formed on the upper side of the inner body 320 adjacent to the dissolution inlet 331.

That is, the water introduced into the dissolution inlet 331 formed in the dissolution cap 330 flows into the inner body 320 and flows from the inside of the inner body 320 through the dissolution inlet 321 to the dissolution inlet 331 As shown in Fig. The water supplied to the dissolution inlet port 331 formed in the dissolution cap 330 moves along the dissolving channel formed between the inner body 320 and the inner body 320 and the outer body 310, And the air stored in the water introduced from the dissolution inlet 331 can be dissolved.

In other words, the water introduced into the dissolution inlet 331 of the dissolving unit 300 moves along the inner side of the inner body 320 inside the dissolving unit 300 and the dissolving channel without any separate stirring device or mixing member, And may be mixed with the air stored inside the dissolving unit 300.

The dissolution guide 311 may be formed on the other side of the outer body 310. The dissolution guide 311 may guide water supplied through the dissolution passage formed between the inner body 320 and the outer body 310 to be supplied to the bubble generator 400.

The dissolution drain 312 may be formed on the other side of the external body 310 and may be spaced apart from the dissolution guide 311. Specifically, the dissolution drain hole 312 may be formed in the hemispherical minimum surface of the external body 310, and the dissolution guide hole 311 may be formed in a direction intersecting the dissolution drain hole 312.

For example, the dissolution guide 311 may protrude along the circumferential direction on the outer circumferential surface of the lower part of the outer body 310, and the dissolving outlet 312 may protrude from the center of the lowest part of the hemispherical outer body 310 .

In addition, the washing machine 101 according to an embodiment of the present invention may further include a discharge check valve 350. 6, the discharge check valve 350 is installed at a lower portion of the outer body 310 and selectively opens and closes the drain hole 315 to selectively open the drain hole 315 and the dissolution drain hole 312, So that it can be communicated.

Accordingly, the water that has passed through the dissolution drain port 312 opened by the discharge check valve 350 can be effectively discharged to the outside of the tub 200 through the drain line 210.

Further, the discharge check valve 350 is capable of opening and closing the drain hole 315. Specifically, the discharge check valve 350 may be opened or closed in accordance with the level of the water supplied from the internal pressure or the dissolution inlet 331 which is partitioned by the dissolving cap 330 and the external body 310.

Therefore, the dissolving unit 300 includes the discharge check valve 350 that can selectively open and close the drain hole 315 formed in the outer body 310, so that when water remains in the winter dissolving unit 300, It is possible to prevent the water from freezing and the dissolving part 300 from being broken.

6, the discharge check valve 350 of the washing machine 101 according to an embodiment of the present invention includes a valve member 20, a valve cover member 10, and an elastic member 30 .

One end of the valve member 20 is inserted into the drain hole 315 and the other end is disposed inside the valve receiving protrusion 351. Specifically, the valve member 20 can selectively open and close the drain hole 315 by one end inserted into the drain hole 315. One end of the valve member 20 can be inserted and supported in the drain hole 315.

The valve cover member 10 can be detachably engaged with the outer circumferential surface of the valve receiving projection 351. [ Further, a dissolution drain hole 312 may be formed to guide the water that has passed through the drain hole 315 to be discharged to the outside of the external body 310. More specifically, the valve cover member 10 surrounds the outer circumferential surface of the valve receiving protrusion 351 and is detachably coupled to the valve receiving protrusion 351. The valve cover member 10 has a drain hole 315 and a valve member 20 A communicating dissolution drain 312 can be formed. In other words, the valve member 20 can selectively communicate with the drain hole 312 and the drain hole 315.

For example, a screw thread is formed on the outer circumferential surface of the valve receiving projection 351, and a spiral which is engaged with the thread of the valve receiving projection 351 is formed on one surface of the valve cover member 10 opposed to the outer circumferential surface of the valve receiving projection 351 .

The elastic member 30 may be disposed between the valve member 20 and the valve cover member 10. [ In addition, the elastic member 30 can provide an elastic force to the valve member 20. Specifically, the elastic member 30 can provide an elastic force such that the valve member 20 opens the drain hole 315.

That is, the elastic member 30 can be expanded when the valve member 20 is compressed when the drain hole 315 is closed and the valve member 20 is opened when the drain hole 315 is opened.

The valve member 20 of the dissolving unit 300 according to the embodiment of the present invention includes the valve hollow 21 as shown in Fig. 6, and the outer diameter of one end of the valve member 20 is The diameter of the drain hole 315 may be larger than the diameter of the drain hole 315.

Specifically, the valve member 20 includes an elastic material such as rubber, and can be effectively deformed by an external force by the valve hollow 21 and inserted into the drain hole 315.

The outer diameter of one end of the valve member 20 with respect to the valve hollow 21 may be larger than the diameter of the drain hole 315. Therefore, the valve member 20 includes the valve hollow 21, and one end portion of the valve member 20, which is formed relatively larger than the diameter of the drain hole 315, can be effectively inserted into the drain hole 315 . That is, the valve member 20 can provide a deformable space so that one end of the valve member 20 is deformed by an external force, so that the valve hollow 20 formed at the center portion can be deformed, It can be easily assembled at the time of insertion and installation.

The outer diameter of the other end of the valve member 20 of the dissolving unit 300 according to an embodiment of the present invention may be larger than the diameter of the drain hole 315. A support groove 22 may be formed at the other end of the valve member 20.

The outer diameter of the other end of the valve member 20 may be formed to be larger than the diameter of the drain hole 315. Specifically, the outer diameter of the other end of the valve member 20 may be formed to be larger than the outer diameter of the one end of the valve member 20.

Further, a support groove 22 may be formed at the other end of the valve member 20. A support groove 22 formed concavely along the longitudinal direction of the valve member 20 is formed at the other end of the valve member 20 facing the inside of the valve cover member 10 in the longitudinal direction of the valve member 20 . Specifically, the support groove 22 may be formed in the shape of a ring along the center of the valve member 20.

The support groove 22 can support the elastic member 30. Specifically, one side of at least a part of the elastic member 30 is inserted into the support groove 22, so that the elastic force acting on the elastic member 30 can be effectively transmitted to the valve member 20. [

The locking protrusion 40 is disposed apart from the dissolution drain port 312 of the valve cover member 10 and can be protruded toward the valve member 20. The engaging protrusion 40 supports the inner peripheral surface of the other side of the elastic member 30 to prevent the elastic member 30 from separating from the valve cover member 10 and the elastic member 30 upon elongation and contraction .

That is, the engaging protrusion 40 can support the inner circumferential surface of the elastic member 30 so that the elastic member 30 is effectively positioned inside the valve cover member 10.

The valve cover member 10 of the dissolving unit 300 according to an embodiment of the present invention may further include a valve rib 12 as shown in FIG.

The valve ribs 12 may be formed in the valve cover member 10.

The first sealing member 60 may be installed between the cover outer wall 11 and the valve rib 12. Further, the first sealing member 60 can maintain the watertightness between the valve receiving projections 351 and the valve cover member 10. Specifically, one surface of the first sealing member 60 disposed between the valve rib 12 and the cover outer wall 11 may be in contact with the valve receiving projection 351. [ Therefore, it is possible to effectively prevent the water passing through the drain hole 312 through the drain hole 315 from leaking between the cover outer wall 11 and the outer peripheral surface of the valve receiving protrusion 351.

In addition, the first sealing member 60 can effectively prevent air stored inside the dissolving unit 300 from leaking out of the dissolving unit 300.
