CONSTITUTION:A drain hole 17 is formed in that side edge of a finishing agent vessel mounting part 11 which is situated on the agent influx part 13 side, and thereby the water flowing in from a small gap between the agent vessel 18 and the mounting part 11 in the direction toward the agent influx part 13 is discharged to outside the tub 5 through the drain hole 17.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine capable of skillfully injecting a finishing agent.

[0002]

2. Description of the Related Art Conventionally, a so-called fully automatic washing machine has been provided with a finish agent, for example, a soft finish agent, which can be skillfully injected. This is, for example, in JP-A-63
JP-A-281698 discloses that a finishing agent container mounting portion having a finishing agent inflow portion is provided in a washing / dehydrating tank for centrifugal dehydration, and the finishing agent container mounting portion includes first to third chambers. The finishing agent container having the above is installed, the finishing agent is put into the first chamber of the container, and the operation is started in this state, whereby the finishing agent is dehydrated after the first "washing" and "draining" steps. The centrifugal force due to the rotation of the tank during the stroke
From the second chamber to the second chamber, and from the second chamber to the third chamber by gravity flow during the subsequent “rinsing” stroke, and after the subsequent “drainage” stroke, the tank was removed during the “dewatering” stroke. It is discharged from the third chamber to the outside of the finishing agent container by the centrifugal force due to the rotation, and is stored in the finishing agent inflow portion during the "dehydration" step, and then is naturally flowed down into the tank during the final "rinsing" step. It was designed to allow inflow.

[0003]

However, in the above-mentioned one, the "dehydration" particularly before the final "rinsing" step is performed.
During the process, water enters the finishing agent inflow part through a slight gap between the finishing agent container and the finishing agent container mounting part of the tank in which it is installed, and fills this finishing agent inflow part, so it is discharged from the finishing agent container. The finishing agent is not able to enter the finishing agent inflow part and scatters around, is discharged to the outside of the tank with other water from the nearest dehydration hole, and is further discharged to the outside of the machine through the drain port and drain hose. Therefore, there is a problem that the effect cannot be exerted during the next final "rinsing" step.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to prevent water from entering the finishing agent inflow portion during the dehydration step before the final rinsing step, and to disperse the finishing agent. It is an object of the present invention to provide a washing machine which can avoid the above and fully exert the effect of the finishing agent during the final "rinsing" step.

[0005]

In order to achieve the above-mentioned object, in the washing machine of the present invention, the washing / drying by centrifugal dehydration is performed.
A finishing agent container having a plurality of chambers in which the stored finishing agent is sequentially transferred as the stroke progresses and is discharged during the dehydration step before the final rinsing step can be attached to the tank that also serves as dehydration and is discharged from the finishing agent container. A finishing agent container mounting portion having a finishing agent inflow portion for receiving the finishing agent during the dehydration step before the final rinsing step and allowing the finishing agent to flow into the tank during the final rinsing step. The feature is that a water draining hole is formed at the side edge of the finishing agent inflow side.

[0006]

According to the above means, during the "dehydration" step before the final "rinsing" step, the finishing agent inflow portion enters into the finishing agent inflow section through a slight gap between the finishing agent container and the finishing agent container mounting portion of the tank in which it is mounted. Water is discharged from the water drain hole as it enters,
Accumulation in the finish agent inflow part is avoided. Therefore, the finishing agent inflow portion is not filled with water, the finishing agent enters the finishing agent inflow portion, and the finishing agent inflow portion flows down the finishing agent inflow portion during the final rinsing process to enter the tank. Can be fully exerted.

[0007]

An embodiment of the present invention will be described below with reference to the drawings.

First of all, FIG. 2 shows an outer box 1 of a so-called fully automatic washing machine, in which a water tub 2 is supported by an elastic suspension mechanism 3 (only a part of which is shown). is doing. Inside the water tub 2, there is disposed a washing / dehydrating tank 5 having a large number of dehydration holes 4 on the peripheral side thereof, and further, inside the tank 5, an agitator 6 is arranged at the bottom. There is.

On the other hand, on the outer lower part of the water tub 2, a motor 7 and a mechanism portion 8 having a clutch mechanism, a brake mechanism and the like, which are not shown in detail, are arranged, whereby the tank is washed and rinsed. 5 is stopped and the stirring body 6 is rotated, and the tank 5 is rotated together with the stirring body 6 during the dehydration process to perform dehydration by centrifugal force.

A lid 9 is provided on the upper part of the outer box 1, and a control device 10 is provided inward of the front of the lid 9, and the control device 10 causes the operation to be performed in the order of the strokes shown in FIG. Is done automatically.

The upper part of the inside of the tank 5 is shown in FIG.
And, the finish agent container mounting portion 11 is formed by the recessed portion shown in FIG. 1, and further, the finish agent container mounting portion 11 is formed with an engaging recessed portion 12 for mounting the finish agent container at a lower portion thereof, A finishing agent inflow portion 13 is formed on the right side in the figure by partitioning with a rib 14, and a deepening lower end portion of the finishing agent inflow portion 13 has a finishing agent injection port 15 leading to the inside of the water tub 2 and further to the tank 5. Is formed. Further, a step portion 16 is formed at the side edge portion of the finish agent container mounting portion 11 on the side of the finish agent inflow portion 13 side, and a plurality of drain holes 17 are formed in the step portion 16.

On the other hand, the finishing agent container 18 is the same as that disclosed in the above-mentioned JP-A-63-281698.
A finishing agent, for example, a softening finishing agent accommodated in the accommodation opening 19 on the upper surface is moved from the first chamber 20 to the second chamber 21 and from the second chamber 21 by centrifugal force or natural flow along with the progress of the process. It is sequentially transferred to the third chamber 22 and is discharged from the discharge port 23 on the rear face toward the finishing agent inflow part 13 during the dehydration process (F) before the final rinsing process (G). The engaging projection 24 on the lower surface is engaged with the engaging recess 12 on the finishing agent container mounting portion 11, and the engaging claw 25 on the upper surface is attached to the tank 5 (specifically, as shown in FIG. 5 is engaged with the engagement receiving portion 26 of the upper balance ring 5) and is detachably attached to the finish agent container attaching portion 11.
