Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a detergent dispensing device for a washing machine that prevents discoloration of clothes due to detergent adhesion to the clothes and enables efficient use of detergent.

Conventional technology In the past, when adding detergent to this type of washing machine, the detergent was put directly into the washing tub.For example, in a washing machine that has a circulation path that uses a pump-up rotary blade, the detergent is placed near the lint filter. There was a structure in which the input port was placed in the middle of the circulation path.

Problems to be Solved by the Invention However, in the conventional configuration, a detergent inlet is provided in the middle of the circulation path to capture lint and collect dust, but especially in the case of synthetic detergents, the detergent does not dissolve completely and the lint is removed. The detergent itself adhered to the filter as a lump, did not dissolve completely, and the detergent itself sometimes adhered to the upper part of the tank, such as when using a low water level.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a detergent dispenser for a washing machine that improves detergent agitation performance after detergent is dispensed.

Means for solving the problem In order to solve the above problem, a detergent input case that can be taken out and put in freely is installed at the rear of the clothes input slot that forms the upper frame, and the detergent put into the detergent input case is transferred to the detergent tank by supplying water. The detergent case has a structure in which water is injected into the detergent case, and above the detergent case there is provided a water inlet spout that has a plurality of holes and causes water to flow out in the form of a shower.

Function: With this configuration, the detergent dispenser case for dispensing powdered detergent, etc. can be taken in and out at will, and is positioned at the rear of the clothes inlet, making it easier to use the detergent dispenser. This makes it easy to add the specified amount of detergent and prevents adding an excess amount. Furthermore, the water supply spout having a plurality of holes provided above the detergent injection case allows the water to be jetted in a stream-like manner, and the water can be injected into the washing tub while uniformly dissolving the detergent.

EXAMPLE The following is an example of the present invention 'f! : This will be explained with reference to FIGS. 1 to 4.

In FIG. 2, an opening/closing lid 3 that opens and closes when clothes are loaded is pivotally supported on an upper frame 2 constituting the upper part of a washer main body 1, and a water supply pulp 4 is provided at the rear.

Reference numeral 6 denotes a rotary blade which is rotatably driven by the rotation of the motor 6 through a belt 7 to reduce the speed of the mechanical unit 8. Reference numeral 9 is a washing/drying tank (hereinafter referred to as the washing tank), which is pivotally supported by the mechanical unit 8 and dehydrates the water. The support 10 hangs from the main body 1 via a suspension 11 and is elastically supported.

The upper frame body 2 has a circular flange-shaped clothes inlet 12 for putting clothes in, and a detergent inlet case 13 that can be freely put in and taken out is provided at the rear of the clothes inlet 12, as shown in FIG. ing. A water inlet 16 with a plurality of water holes 14 is disposed above the detergent injection case 13, and a water supply connection port 17 communicates with the water supply pulp 4 via a water supply hose 16.
The water filler main body 18 is formed into a box to accommodate the detergent input case 13 and the water filler 16, and the opening of the box is provided only on the side of the washing tub 9.

The water filler cap 15 is fixed to the water filler main body 18 by screws 19, and the detergent charging case 13 is guided by a step 2o for a slider provided on the water filler main body 18 so as to be freely drawn back and forth.

The water supplied through the pressure hose 21 passes through the water supply pulp 4 and the water supply hose 16 as indicated by arrow a, and is jetted downward into the detergent injection case 13 through the water hole 14 of the water injection spout 16 in a shower-like manner. The detergent 21 is mixed with the shower-like water, flowed backward, guided by the water flow guide 22 of the water inlet main body 18, and swept forward. The washed away detergent water is poured into the washing tub 9, and is efficiently dissolved as detergent for washing, so that washing operation can be performed. Since the bottom surface 13A of the detergent input case 13 is sloped α so as to be lower toward the rear, residual detergent, residual water, etc. can be eliminated, and an efficient water flow effect can be achieved.

As shown in FIG. 3, the detergent charging case 13 can be freely pulled out in the front and rear directions of the arrows, and FIG. 4 shows the water injection state when the detergent charging case 130 is set.

As described above, according to this embodiment, the water inlet main body is provided in a box-like shape and is opened only on the washing tub side, so that water leakage from inside the detergent case or from the middle of the water supply path such as the water inlet spout, etc.
Detergent leakage can be prevented.

Effects of the Invention As described above, according to the present invention, since the detergent input case that can be freely taken out and put in is provided at the rear of the clothes input port, it is easy to use the detergent input case, and the size of the detergent input case is limited. This makes it possible to always use the appropriate amount of detergent and prevent the use of excess detergent. Furthermore, the cleaning effect is improved by injecting water into the washing tub while dissolving the detergent uniformly. Prevents detergent adhesion and prevents discoloration of clothes.
