Abstract

PURPOSE:To dissolve the entire detergent in a detergent case in a short time period by a method wherein water is fed on to detergent in the detergent case through upper and lower water paths, and to the bottom of the case as well. CONSTITUTION:A water path 4 is formed above a container 2 on a washing machine, and the bottom plate of the water path 4 is shower plate 6 provided with small holes 5. A tubular part 17 is provided on the front wall 16 of the water path 4, and a small hole 18 is provided on the bottom plate of the tubular part 17. A double-wall water path 21 is formed in a handle 20 on the front side of a detergent case 19 and located under the hole 18, and holes 26 are provided on the inside wall of the water path 21. With this constitution described above, the water supplied from a water hose 8 flows into the water path 4 and is fed on to detergent 14 in the detergent case 19 through the holes 5. Further, the water flows horizontally along a bottom 15 of the case 19 after passing through the tubular part 17, the water path 21 and the hole 26, washes away the detergent 14 toward an outlet 13, and flows into an inner drum of a washing machine along a sloped bottom 43 of the container 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a detergent dispenser for a washing machine configured to inject water into a detergent case.

2. Description of the Related Art A conventional detergent dispensing device is shown in FIG. As shown in the figure, a storage foil 2 with a front opening is provided in a part of the spring /I/1 on the upper part of the main body of the washing machine, and a water channel 4 is formed in the upper surface part 3 of the storage box 2.
A shower plate 6 having a large number of small holes 5 on the inner surface of the storage box 2
are welded. Furthermore, water is injected into the water junction 4 formed by the shower plate 6 and the storage box 2 through a water inlet hose 8 from a water inlet 7 provided at the rear. The detergent case 9 is stored in the storage box 2 below the shower plate 6 in a drawable manner. The detergent case 9 is box-shaped with an open top and has a handle 10 on the front.
The bottom surface 11 is an inclined surface toward the rear wall 12, and the lower end of the wall 12 has an opening 13.

Then, when the detergent 14 is put into the detergent case 9 and the water supply is started during washing, the water is poured into the detergent 14 from the water channel 4 through the small hole 6 of the shower plate 6 in the form of a shower, dissolving the detergent 14 and flowing through the opening 13. It flows out through the bottom surface 16 of the storage box 2 which is inclined forward.

Problems to be Solved by the Invention However, when water is poured through the small holes 5 on the top surface, water does not reach all of the detergent 14, and not only does it take time for the detergent to flow out,
Sometimes the detergent remains undissolved while the water is being supplied to the washing machine to reach the required amount of water, and when water is supplied during the rinsing process, which is the next step after washing, the detergent dissolves and flows into the water, creating bubbles during the rinsing process. However, the rinsing process was ruined.

Concentrated detergents have become mainstream in recent years, and these detergents have a high specific gravity and become even heavier when water is added. It was difficult to dissolve.

SUMMARY OF THE INVENTION An object of the present invention is to provide a detergent dispensing device that dissolves all the detergent in the detergent case in a short time when water is supplied for washing, and without leaving any detergent in the detergent case.

Means for Solving the Problems In order to solve the conventional problems, the present invention has a structure in which water is injected into the detergent in the detergent case from an upper water channel, and when the detergent case is stored, there is a gap between the water channel and the detergent case. The structure is such that water is communicated with the water channel and water is injected into the bottom of the detergent case.

Function: In the detergent dispensing device configured as described above, the detergent in the detergent case is dissolved by pouring water from above, and when the detergent case is loaded, the detergent at the bottom of the detergent case is dissolved by pouring water from the side, making it effective. It will be poured into the washing machine.

Embodiment FIG. 1 shows a detergent dispenser according to an embodiment of the present invention, in which a storage box 2 with an open front is provided at the top of the washing machine, and a first water channel 4 is formed on the top surface of this storage box 2. ing. The lower plate of the water channel 4 is a hollow plate 6 having small holes 5, and water is supplied to the first water channel 4 from a water inlet 7 at the rear. A cylindrical portion 17 is provided on the front wall surface 16 of the first water channel 4.
A hole 18 is formed in the lower wall surface of the cylindrical portion 17.

The storage box 2 includes a box-shaped detergent case 1 with an open top.
A handle 2o at the front of the detergent case 19 forms a double-walled second water channel 21. A hole 26 is provided in the inner wall 22 of this second water channel 21. The upper part of the second water channel 21 is open,
The lower part is plugged with a lid 24. And detergent case 19
is housed in the storage box 2, the second water channel 21 of the detergent case 19 is positioned below the hole 18 at the tip of the first water channel 4. The bottom 15 of the detergent case 19 is a rearwardly inclined surface, and an opening 13 is provided below the rear wall surface 12.

In the above purchase, the water supplied from the water injection hose 8 is
The water flows into the water channel 4 and is injected into the detergent 14 in the detergent case 9 below through the small hole 5 of the shower plate 6.

Further, the water flows out from the cylindrical part 17 at the front end of the first water channel 4, through the second water channel 21 of the handle part 2o, through the water inlet 26, and laterally flows out along the bottom surface 15 of the detergent case 19, causing the detergent 14 to flow out. The slanted bottom surface 43 of the storage box 2 flows out to the outlet 13 side.
It flows into the inner tub of the washing machine.

Effects of the Invention According to the detergent dispensing device of the present invention, when water is supplied during washing, the detergent in the detergent case is dissolved in the shower from above.
In addition, the detergent dissolves quickly and flows into the inner tub of the washing machine without leaving any residue inside the detergent case, and when rinsing water is supplied, it flows through the detergent case. Since the water does not contain detergent, effective rinsing can be achieved and the user will not feel anxious.
