An inlet 22 for a laundry treatment agent (for example, detergent) is formed on the upper surface of the water supply section 4c, and the inlet 22 is covered with a lid 23.

A box-shaped input container 25 having a storage chamber 24 for storing detergent input from the input port 22 is installed below the input port 22 . The storage chamber 2
A box-shaped water receiving part 2 is provided inside the upper part of the rear wall 24a of 4.
I am wearing 6.

The bottom of the water receiving section 26 is composed of a surface 26a parallel to the bottom surface 24b of the storage chamber 24 and an upwardly inclined surface 26b, and a plurality of water holes 27 are formed in each of the surfaces 26a, 26b. It is set up.

Now, 28 is a bath water supply port from a pump branched from the dual water supply electromagnetic valve, and opens into the water receiving portion 26 from the rear wall 24a of the storage chamber 24. Also, a tap water supply port 30 branched from the dual water supply solenoid valve via a connection hose 29.
is opened into a water supply pipe 31 disposed at the rear of the storage container 25. The upper end of the water supply pipe 31 is communicated with the inside of the water receiving section 26. Reference numeral 32 denotes a bypass path connected to the lower end of the water supply pipe 31, and is used to directly lead out a portion of tap water into the tank or to drain residual water in the water supply pipe 31.

A horizontally long opening 33 is provided at the front edge of the bottom surface 24b of the storage chamber 24.
An overflow wall 34 is provided along the rear side of the opening 33. The overflowing wall 34 has an inclined surface 35 at its upper end that descends from both sides to the center, and a vertical slit 36 at the center.

At the location where the water discharged from the slope 26b of the water receiving portion 26 falls, there is a rib 37 that is parallel to the overflow wall 34, is lower than the overflow wall 34, and has a short width.
has been established.

A siphon device 38 whose outlet is located above the washing tub 3 is provided between the overflow wall 34 and the rib 37, and this siphon device 38 is connected to the storage chamber 24.
The liquid that has passed over (passed) the ribs 37 can be sucked up and discharged into the washing tub 3.

The operation will be explained based on this configuration.

First, the lid 23 is opened in advance and an appropriate amount of detergent is poured into the storage chamber 24 of the storage container 25.

Next, when washing is started by operating the operation button, the water supply side electromagnetic valve 17 opens and water is supplied from the tap water supply port 30 to the water receiving part 26 via the water supply pipe 31. Water is injected into the storage chamber 24 from the water holes 27 of the water receiving portion 26 in a shower-like manner. This shower water injection dissolves the detergent in the storage chamber 24 and discharges it into the washing tub 3 by the siphon device 38. Further, the detergent liquid that has exceeded the overflow wall 34 is discharged into the tank from the opening 33. At this time, since the overflow wall 34 has an inclined surface 35 and a slit 36 so that the upper center part thereof is the lowest, water flows from the opening 33 on average around the center part. It flows out and has a good appearance. Further, the overflowing effect is performed smoothly, and the detergent floating on the liquid surface is discharged into the tank without being blocked by the overflowing wall 34.

When using the pump device to supply bath water into the tank, first open the water supply side solenoid valve 17 for 30 seconds, then switch to open the pump side solenoid valve 18 and drive the pump device at the same time. This is because if bath water from the pump device is used from the beginning, the detergent in the storage chamber 24 will not dissolve well due to low water pressure, so tap water with high water pressure is used only for the first 30 seconds. Note that the water supply is stopped when the water level switch 12 detects the specified water level.

Here, the parallel surface 26a in the water receiving portion 26
The water released from the water holes 27... of the storage chamber 24
The water flows forward along the rear wall 24a and the bottom surface 24b, and also flows along the inclined surface 26b of the water receiving portion 26.
The water discharged from the water holes 27 of the ribs 37
The water falls to around the base of the water, collides with the rib 37, and promotes convection in the storage chamber 24 together with water from the water passage holes 27 of the parallel surface 26a. As a result, the detergent in the storage chamber 24 is neatly dissolved, and the detergent in the storage chamber 24 is completely dissolved.
No detergent remains inside.

Note that, in accordance with the program of the washing machine, not only detergent but also other softening agents can be put into the storage container 25 as appropriate.

(g) Effects of the invention The laundry treatment agent dispensing device of the present invention has a low cost and simple structure, and can neatly dissolve the laundry treatment agent in the storage chamber and discharge it into the washing tub, so that no laundry treatment agent remains. This can reduce the hassle of cleaning.
