DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for supplying a detergent to a washing machine for supplying a powder detergent to a washing tub.

[0002]

2. Description of the Related Art Heretofore, this type of washing machine charging device for a washing machine has been configured as shown in FIGS. Less than,
The configuration will be described.

As shown in the figure, a detergent case 1 has a lower surface 3 of a detergent introduction part 2 inclined at a substantially constant inclination, and is housed in a water injection device 4 so as to be able to be drawn out. A water injection part 6 having a plurality of holes 5 is provided above. Tap water is supplied to the water supply section 6 through a water supply path 7, and the supplied water is sprinkled into the detergent case 1 through the plurality of holes 5, and the washing tank (not shown) is supplied through the water inlet 8 of the water injection device 4. ).

In the above configuration, the detergent case 1 is pulled out, the powder detergent 9 is introduced into the detergent introduction section 2, and the detergent case 1 is stored in the water injection device 4.
When the water is supplied to the water injection section 6 through the, the supplied water is sprinkled from the plurality of holes 5 onto the powder detergent 9 put into the detergent input section 2, and the powder detergent 9 is dissolved in the water and flows out from the outlet 1a together with the water. Then, it is put into the washing tub through the water inlet 8.

[0005]

In such a conventional configuration, even when the amount of water supplied from the water supply path 7 is small due to a low tap water pressure or the like, the detergent charging section 2 of the detergent case 1 can be used.
In order to put all of the powdered detergent 9 into the washing tub, it is necessary to increase the inclination of the lower surface of the detergent case 1. However, recent washing machines are required to be compact and shorten the operation time, and the detergent case 1 and the water injection device 4 cannot be easily increased in size because the inclination of the lower surface 3 of the detergent case 1 is made large. Had a problem.

On the other hand, as the capacity of the washing machine increases, the amount of the powdered detergent 9 used tends to increase, and a large amount of water is required to supply a large amount of the powdered detergent 9 to the washing tub. In addition, the powder detergent 9 has a large viscosity due to the compactness, and a large amount of water is required to put all the compacted powder detergent 9 into the washing tub. Even when the amount of water supplied is small, it is desired that the powder detergent 9 put in the detergent case 1 be put into the washing tub as soon as possible without partially remaining.

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and concentrates water supply on a portion where powdered detergent is apt to be undissolved, so that the powdered detergent introduced into the detergent case can be quickly supplied without being partially left. It is an object of the present invention to provide a cleaning agent charging device for a machine.

[0008]

According to the present invention, in order to achieve the above object, a detergent case having a detergent input part and an outlet is housed so as to be able to be drawn out in a water injection device for pouring water into a washing tub from a water inlet through a detergent case. The detergent case has a lower surface that is inclined so that the detergent flows down to the detergent input portion, and a water plate that is inclined near the outflow port and above the lower surface in a direction opposite to the lower surface.

[0009] Thus, the water supply can be concentrated on the portion where the powder detergent is likely to remain undissolved, and the powder detergent charged into the detergent case can be quickly charged without partially remaining.

[0010]
