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 between the guide rib 381 and the rib 380 and between the guide rib 381 and the detergent injection portion 303. The discharge hole 360 may be formed. The water continues to be supplied by the failure of the control circuit, and the water discharged through the steam discharge hole 360 moves along the guide ribs 381 and the ribs 380 toward the support part 390 and through the opening part 390. It is discharged into the washing machine.

The dispenser lower body 400 includes a detergent input part 403 forming a detergent input hole 310, 320, 330 and a water supply path facing the dispenser upper body 300, and a water supply path and a steam 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.

Lose. 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 failure of the main insulation and shortening 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 an electrical apparatus such as a drying duct and a drying heater is located on the right side of the dispenser body 500, and the dispenser body 500 is slightly biased to the left side of the entire cabinet, the flow guide hole 545 is illustrated. As described above, it is preferable that the flow path be formed in the cabinet closest to the advancing direction of the water by being formed in the left direction.

     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 channel 411 and the liquid detergent supply channel 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 the 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.
