Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

4 is a perspective view showing an overall exploded view of the dispenser assembly.

The dispenser assembly (DISPENSER ASSEMBLY) is divided into dispensers (300, 400), liquid detergent and softener box assemblies (100, 200) and dispenser body (500). Again, the dispenser is configured by combining the dispenser upper body 300 and the dispenser lower body 400 and has a rectangular shape.

When the dispenser upper body 300 is viewed from the front of the washing machine, the body part 304 in which the detergent input part 303 and the vapor discharge hole 360 are formed to form the plurality of rectangular holes 310, 320, and 330 in the horizontal direction. It is composed of Here, the reference of the front or rear corresponds to the front side of the washing machine. The rectangular hole is composed of the main detergent detergent injection hole 310, the detergent box insertion hole 320 is inserted into the detergent box and the preliminary detergent injection hole 330, it is formed facing the dispenser lower body (400).

Here, the liquid detergent and softener box assemblies 100 and 200 are inserted into the detergent box insertion hole 320, and the liquid detergent and softener box assemblies 100 and 200 are coupled to the main body 100 and the cap 200. The cap 200 is divided by the partition wall and the left side is divided into the liquid washing section 210 and the right side is divided into the softening section 220. The cap 200 is coupled to the upper portion of the main body 100, and when water is supplied to the main body 100, to prevent the fabric softener or the liquid detergent from being splashed and mixed with each other, or to enter the other storage space by the drop of water. It is for.

In addition, the dispenser upper body 300 is formed with a steam discharge hole 360 for discharging water vapor generated during drying. By the formation of the steam discharge hole 360, the dew condensation phenomenon occurring on the back 610 of the lid 610 of the detergent guide cap 600 fitted to the dispenser upper body 300 by steam generation during hot boiling and hot water washing can be removed. It becomes possible.

Supports 390, 490, and 590 are formed to support the dispenser when combined with the washing machine, which is also formed in the dispenser underbody and the dispenser body. Therefore, it can be firmly combined with the washing machine.

In addition, the dispenser upper body 300 has a rib 380 formed along an edge thereof and is open at the support 390. A guide rib 381 is formed in the dispenser body 304 in parallel with the rib 380, and a plurality of guide ribs 381 and ribs 380 are formed between the guide ribs 381 and the ribs 380 and between the guide ribs 381 and the detergent injection part 303. Vapor discharge holes 360 may be formed. The water continues to be supplied due to a failure of the control circuit, and the water discharged through the steam discharge hole 360 is moved along the guide ribs 381 and the ribs 380 toward the support part 390 and the washing machine through the opening 390. It will be discharged inside.

The dispenser lower body 400 includes a detergent input part 403 forming a detergent injection hole 310, 320, 330 and a water supply path facing the dispenser upper body 300, and a water supply path and a vapor discharge hole 460. It is composed of a body portion 404 is formed. A main detergent water supply 411, a liquid detergent water supply 451, a flexible detergent water supply 421, and a preliminary detergent water supply 431 are formed in the body portion 404 of the dispenser lower body 400. Here, the main detergent water supply passage 411 and the liquid detergent water supply passage 451 are divided and contacted by the distribution rib 450. The main detergent water supply passage 411 is intended for the main laundry detergent and should have a wider width than the liquid detergent water supply passage 451.

In addition, a main washing water supply passage 411 and a preliminary washing water supply passage 431 are also surrounded by the main detergent washing unit 310 and the preliminary washing detergent injection hole 330 in the detergent injecting unit 404. The flexible detergent supply channel 421 is formed between the liquid detergent supply channel 451 and the preliminary detergent supply channel 431 of the body 404 of the dispenser lower body 400 at the front of the washing machine, and comes vertically from the rear to the front. While contacting the front surface of the body portion 404 is formed by bending 90 ° to the softener section inlet hole 471.

Among the ribs 480 and 485 which are positioned around the main laundry detergent injection hole 310 and the preliminary detergent injection hole 330 to form the main detergent water supply channel 411 and the preliminary detergent water supply channel 431, The uneven rib 480 forming the feed hole 310 and the pre-washing detergent feed hole 330 has a shape of unevenness 481, 482, and 483. The sealed ribs 485 formed around the detergent box insertion hole 320 form a water supply path together with the uneven ribs 480. However, the sealing rib 485 is sealed when the upper body 300 and the lower body 400 is combined to prevent leakage of water.

In this case, the height of the uneven rib 480 is the largest of the unevenness 481 formed in the body portion, and the smallest in the order of 483, 482 unevenness. The uneven ribs 480 forming the holes 310 and 330 are coupled to the upper body 300 at intervals when the dispenser upper body 300 and the dispenser lower body 400 are coupled to each other. Accordingly, the water flowing along the water supply path drops through the unevennesses 481, 482, and 483 to the main laundry detergent or the prewashing detergent, which is placed in the dispenser body 500 with swirling water. As the height of the unevenness 481, 482, and 483 changes, the detergent mixed evenly with water enters the washing drum through the detergent outlet 540 located at the bottom left of the rear surface of the dispenser body 500. Therefore, the laundry detergent is softly removed, and the problem that the laundry detergent is lumped and remains in the detergent section is eliminated.

The sealing rib 485 formed around the liquid detergent and softener box assembly input hole 320 forms a water supply path together with the uneven rib 480. However, when the upper body 300 and the lower body 400 are combined to prevent leakage of water. The dispenser upper body 300 and the dispenser lower body 400 are bonded to each other to perform heat welding to maintain airtightness. The dispenser body 500 accommodates the dispensers 300 and 400 in the upper portion, and is a device that accommodates detergent and guides the washing drum together with the water dropped from the dispensers 300 and 400, and has a thickness from the front to the rear. Thickening This is for the water dropped in the dispenser body 500 to smoothly go to the detergent outlet 540. The edge of the opening is formed with a step so that the dispenser can be seated, and a groove for accommodating the valve of the dispenser is formed. In addition, a hook 570 for engaging the dispenser is formed around the open side of the dispenser body 500. The hooks 570 may allow the dispensers 300 and 400 to be firmly seated on the dispenser body 500. Therefore, the hook catching groove 370 is formed around the dispenser upper body 300 to couple with the hook 570 of the dispenser body 500.

The inside of the dispenser body 500 is divided into three sections by the partitions 515 and 525, and the partitions 515 and 525 are formed toward the detergent outlet 540 located behind the dispenser body 500.

The left section of the three sections is the main laundry detergent section 500 into which the main detergent is injected, and the right section is the preliminary detergent section 530. In addition, the center is the liquid detergent and softener box section 520, the detergent box 200 is coupled to the cap 100 is inserted. These are inclined bottom toward the detergent outlet 540. Each section is opposed to the detergent injection holes (310, 320, 330) of the dispenser.

The dispenser body 500 has a flow path guide hole 545 formed on the upper left side when viewed from the front, and its shape does not matter. The flow path induction hole 545 is formed to prevent such a water overflow when the water supply valve is broken and water is continuously supplied. By installing the flow path guide hole 545 to form a flow path when water overflows, it is possible to prevent the failure of the main insulation and shorten the life of the washing machine.

That is, the flow path guide hole 545 is preferably formed on the opposite side where the insulating devices are installed. That is, since the drying duct or the like is located on the right side of the dispenser body 500, the flow path guide hole 545 is preferably formed in the cabinet direction closest to the water traveling direction.

5 is a cross-sectional view of the dispenser underbody according to the present invention.

     The dispenser is configured by the combination of the upper body 300 and the lower body 400, and is a device for dispensing the wash water flowing through the valves (410, 430, 440). Water introduced through the main valve 410 enters the main laundry detergent section 510 and the liquid detergent section 210 through the main detergent water supply passage 411 and the liquid detergent supply passage 431. Water entering the detergent section 510 is mixed with the detergent added to the detergent section 510 and enters a washing drum (not shown).

     The main valve 410 is an inlet for water to enter the dispenser 300, 400, and is formed in the lower body 400 of the dispenser 300, 400. In addition, one end of the main valve 410 is integrally formed with the lower body 400 at a predetermined angle with one surface of the lower body 400. The other end of the main valve 410 is threaded 415 to connect with the hose. The diameter 412 of the inlet of the main valve 410 is larger than the diameter of the outlet of the main valve. This is to speed up the flow of water to the outlet even if a small amount of flow enters the inlet. The hydraulic pressure injected through the outlet is between about 0.5 to 10 kg / cm 2. Therefore, the water can be evenly distributed in the detergent section, so that the detergents put into the detergent section can be washed neatly, thereby improving washing performance and rinsing performance.

      The flow rate introduced through the main valve 410 is moved through the main detergent water supply passage 411 and the liquid detergent water supply passage 451. At this time, a distribution rib 450 is formed between the main detergent water supply passage 411 and the liquid detergent water supply passage 451, and thus the main detergent supply passage 411 and the liquid detergent supply passage 451 are formed by the distribution rib 450. To allow enough water to flow. At the closed end of the liquid detergent water supply passage 451, a liquid detergent section inlet hole 472 is provided, through which water flows into the liquid detergent section 210. The wash water enters the liquid detergent section 210 through the inflow hole 472, and the water filled in the liquid detergent section 210 guides the detergent to the laundry drum by the effect of the siphon.

     The preliminary detergent valve 430 is located adjacent to the main valve 410, and water is supplied first through the preliminary detergent valve 430 before entering the main laundry. The water introduced through the preliminary detergent valve 430 may cleanly clean the preliminary detergent introduced into the preliminary detergent section 530 of the dispenser body 500 through the preliminary detergent water supply 431.

      The hot water valve 440 is formed on the lower body 400 of the dispenser and is located on the left side of the dispenser lower body 400 when viewed from the front of the washing machine. The hot water is mixed with the water introduced through the main valve 410 to fall into the main laundry detergent section 510 into which the main laundry detergent is introduced.

      A drainage hole 473 is formed in the dispenser lower body 300 connected to the main valve 410, the preliminary detergent valve 430, and the hot water valve 440. The drainage hole 473 serves to discharge the water remaining in the water supply passages 411, 421, 431, and 451 when the water flowing from the valves 410, 430, and 440 is shut off by the electrical control. do. Accordingly, the main detergent feed water passage 411 and the preliminary detergent feed passage 431 are inclined toward the valves 410, 430, and 440.

      A plurality of vapor discharge holes 460 are formed in the lower body 400 of the dispenser. Steam is generated during hot boiling or hot water washing, which causes dew to form on the back of a lid (not shown) of the detergent guide cap (not shown). Therefore, the dew condensation can be eliminated and steam can be discharged into the washing machine. The vapor discharge hole 460 is also formed in the upper body 300 of the dispenser described above.

       Here, the water supply path of the water introduced through the main valve 410 or the pre-wash valve 430 is as follows. Water entering through the main valve 410 enters the main detergent supply channel 411 and the liquid detergent supply channel 451, and the water entering the main detergent supply channel 411 flows around the main detergent detergent injection hole 310 and has an uneven rib ( 480 between the main washing section 510 falls in a swirling water type. Thus, by means of a powerful water pressure method, detergents are not left, and the detergent masses and debris are prevented from being generated, and they remain clean and do not need to be cleaned separately.

     The main detergent water supply passage 411 surrounds the main laundry detergent introduction hole 310 and is connected to the hot water valve 440. Therefore, the hot water may be introduced into the hot water valve 440. In addition, the water entering the liquid detergent water supply 451 enters the liquid detergent section inlet hole 471 falls into the liquid detergent section 210 and the liquid detergent section 210 is dispensed by the liquid detergent dispenser body (500) Guided to the detergent inlet hole 540 formed in.

       Water introduced from the preliminary washing valve 430 moves through the preliminary washing water supply channel 431 and moves around the preliminary washing detergent injection hole 330, and the preliminary washing section 530 between the uneven ribs 480. Swirl into water tide type. The preliminary detergent water supply passage 431 wraps around the periphery of the preliminary washing detergent injection hole 330 or one end thereof is blocked.

       The flexible detergent water supply passage 421 is located between the main detergent water supply passage 411 and the preliminary detergent water supply passage 431, and water from the main valve 410 and the pre-wash valve 430 is simultaneously supplied to the flexible detergent water supply passage 421. Ride through the softener section inlet hole 471 to enter the softener section 220. The softener is guided to the detergent inlet hole 540 of the dispenser body 500 by the siphon effect.

       FIG. 6 is a view showing a distribution rib formed in the dispenser lower body between the main detergent supply channel and the liquid detergent supply channel, and FIG.

      The distribution rib 450 is separated into the main detergent water supply 411 and the liquid detergent water supply 451. Water coming out through the main valve 410 flows through the water supply passages 411 and 451. The water flowing from the main valve 410 by the distribution rib 450 may be simultaneously sent to the main detergent water supply passage 411 and the liquid detergent water supply passage 451. Water entering the main detergent water supply passage 411 exits the main laundry detergent section 510 through the uneven rib 480 around the main laundry detergent injection hole 310. Water entering the liquid detergent water supply passage 451 exits the liquid detergent section 210 through the liquid detergent section inlet hole 472. Therefore, the washing machine user can selectively wash the powder or liquid detergent into the detergent section.

      When the water discharged through the outlet of the main valve 411 is ejected at high pressure and high speed, the water collides with the distribution rib 450 to cause water to scatter. In this case, the water that has been scattered enters the softener section 220 through the softener section inlet hole 471 along the softener water supply passage 421, and the softener is introduced early by the water overflow phenomenon. As a result, the amount of water that has to enter the liquid detergent supply can be reduced.

      The flexible water supply canal 421 is located between the main tax water supply canal 411 and the preliminary detergent water supply canal 431, and the inflow that water can flow into the flexible product section 220 at a closed end of the flexible water supply canal 421. The hole 471 is located. Injecting the softening agent into the washing drum should enter the final rinsing step. Water from the main valve 410 is scattered by the collision with the distribution rib 450 and flows into the softening water supply passage 421 and into the softening section 220. The softener drops prematurely into the washing drum.

     Thus, the end of the distribution rib 450 facing the main valve 410 is installed in the shape of a chamfer 455 to form a slope toward the main valve 410. The height of the distribution rib 450 is preferably formed lower than the height of the water supply passage formed by the dispenser upper body 300 and the lower body 400. In addition, by making the height of the distribution rib 450 lower than the center of the main valve 410, it is possible to solve the problem of water splashing. In addition, the height (H) of the distal end of the distribution rib 450 is formed to about 3.5mm, the base length (L) from the end to the starting portion is preferably formed to about 15mm. As such, the end of the distribution rib 450 facing the main valve 410 may be formed in a chamfer shape, thereby preventing scattering of water sprayed from the main valve 410. In addition, water is introduced into the softener section 220 through the softener water supply passage 421 due to water scattering, and the chamfer portion 452 of the distribution rib 450 may prevent premature injection of the softener due to the water overflow phenomenon. do.

8 is a view showing the residual amount of the liquid detergent according to the change in the length and height of the distribution rib of the present invention.

The chamfer 452 is formed at the end of the distribution rib 450 so that the water flowing from the main valve 410 flows stably into the main detergent supply channel 411 and the liquid detergent supply channel 451. The chamfer 452 is formed in the distribution rib 450 to prevent the scattering of water, and the water enters the liquid detergent water supply passage 451 adjacent to the main detergent water supply passage 411 and water into the liquid detergent section 210. This will flow. The liquid detergent mixed with water is guided to the washing drum by the effect of puncture in the detergent box.

At this time, without changing anything at the end of the distribution rib 450, 65.5g of liquid detergent into the liquid detergent section and the water pressure of the water flowing into the main valve 410 flows into 2.5bar on average 10.7g of liquid detergent Is left in the liquid detergent section 210. 8 shows that the remaining amount of liquid detergent remaining in the liquid detergent section 210 when the end of the distribution rib 450 is changed into a chamfer shape is more remarkably than when the end of the distribution rib 450 does not change anything at the end of the distribution rib 450. This is a graph showing the decrease.

 Here, the height of the distribution rib is 7mm, Case1 has a chamfer length (L) of 15mm, the inclination is made from the end of the distribution rib. The end of the distribution rib shows a pointed triangular shape, the height (H) of the end is 0mm, the angle formed by the chamfer 450 can be said to be the most urgent case among the cases. In the case of Case3, the length L is 30 mm, and the height H of the tip is 0 mm, and the angle formed by the chamfer 450 is smaller than that of Case1. As can be seen from the graph, it can be seen that as the angle formed by the chamfer portion 450 becomes gentle, the residual amount of the liquid detergent remaining in the liquid detergent section 210 decreases.

Case 2 is the case where the height (H) of the end of the distribution rib is 3.5mm and the length (L) is 15mm. Case 2 gives a constant height (H) to the end of the distribution ribs to form a chamfer (450). As shown in FIG. 8, in the case of Case2, the amount of the liquid detergent remaining in the liquid detergent section 210 is about 3.5 g, which is the smallest, thus satisfying the residual standard (8 g) of the liquid detergent zone. This can be seen that the chamfer 452 is formed at the end of the distribution rib 450 so that the flow rate stably flows to the liquid detergent water supply passage 451. In addition, due to the collision of water and the distribution rib 450, the softening agent is added early due to the scattering of water improves the performance of washing and rinsing.

It is apparent to those skilled in the art that the present invention is not limited to the described embodiments, and that various modifications and changes can be made without departing from the spirit and scope of the present invention. Accordingly, such modifications or variations will be considered to belong to the claims of the present invention.
