Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention is intended to introduce a treatment agent such as a softening agent into a washing / dehydrating tank in a dehydrating / washing machine. The present invention relates to a treatment agent feeding device for a washing machine that also serves as a dehydrator.

(Prior Art) Conventionally, as a treating agent charging device for a washing machine of this kind combined with dehydration, for example, JP-A-56-97496 and JP-B-60-504 are known.
There is one shown in Japanese Patent Publication No. 79. These things are
A washing / dehydrating tank, in particular, a balance ring located at the upper end of the tank is equipped with an inserter having first to fourth chambers,
By injecting a treatment agent such as a softening finish agent into the first chamber and starting the operation in this state, the treatment agent is stored in the tank at the time of "dewatering" after "washing" and "draining" during the operation course. By the centrifugal force caused by the rotation of the above, the first chamber is discharged and transferred to the second chamber, and at the time of the subsequent "rinsing", it is transferred spontaneously from the second chamber to the third chamber, and the subsequent "drainage" It is said that after the passing of "dehydration", the centrifugal force by the rotation of the tank again discharges and transfers it from the third chamber to the fourth chamber, and at the final "rinsing" thereafter, it flows into the tank from the fourth chamber. It is like this.

(Problem to be Solved by the Invention) However, in the case of the above-mentioned conventional one, the injector has four chambers of first to fourth, and therefore the adhesion of the treatment agent is also observed in the four chambers. Cleaning must also be performed for the four chambers. In this case, the treatment agent such as a softening agent is generally liquid, but has a high viscosity, and if it adheres, it is rubbed with a brush or a cloth. This was extremely troublesome because it was required to clean things that could not be removed without doing so, to the interior of each of the four chambers of the above-mentioned injector, which were difficult to reach.

The present invention has been made in view of the above circumstances, and therefore an object thereof is to provide a treating agent feeding device for a washing machine for both dehydration and washing, which is generally easy to clean.

[Structure of the Invention] (Means for Solving the Problems) A treating agent feeding device for a combined washing and dewatering machine according to the present invention stores a treating agent in a tub for both washing and dewatering and rotates the accommodated treating agent in the tub. In addition to detachably mounting a dispenser that discharges by centrifugal force due to, the dispenser is configured to receive a processing agent discharged from this dispenser and finally supply it into the tank. The feature is that the passage is formed by a groove that opens toward the inside of the tank, and the open portion is covered by the above-mentioned charging device attached to the tank.

(Operation) According to the above means, the treatment agent is finally supplied into the tank through the charging passage, and the charging passage is provided in the tank separately from the charging device. The number of chambers inside the feeder can be reduced, and the number of places for cleaning can be reduced. Also, as for the charging path, it is formed by the groove that opens toward the inside of the tank, and the opening is covered with the charging device attached to the tank. From the opening that appears to the inside of the charging path, especially the inside of the charging path where the degree of adhesion of the processing agent is considered to be high due to the fact that the processing agent is discharged by the centrifugal force due to the rotation of the tank, It can be cleaned as desired.

FIG. 8 shows the details of the operation course of the dehydration / washing machine of this embodiment. That is, when the operation of the dehydration / washing machine of this embodiment starts, "washing" is first performed. ,
Subsequently, "drainage" is performed and then "dehydration" is performed. In this "dehydration", the tub 4 is rotated at a high speed together with the agitator 5 and the centrifugal force causes the water to be shaken off and discharged from a laundry (not shown) through a dehydration hole (not shown).
At the same time, due to the centrifugal force, the soft finish agent is discharged from the first chamber 19 of the above-mentioned injector 18 through the communication port 24, and the soft finish agent is discharged to the second chamber.
Room 30 receives and houses. Therefore, after this "dehydration", "rinsing" is performed, and at the time of this "rinsing", the softening agent is discharged from the second chamber 30 onto the bottom extension 20a of the second chamber accommodating chamber 20. It flows out and flows out naturally, and it is the third chamber 21
To house. Then, after that, "drainage" is performed and "dehydration" is further performed. At the time of "dehydration", the soft finishing agent is removed from the third chamber 21 by the centrifugal force caused by the high speed rotation of the tank 4 as described above. It is discharged through the discharge port 25, and the charging path 35 receives and stores it. Furthermore, after this "dehydration", "rinsing" is performed, and at the time of this "rinsing", the soft finish naturally flows through the charging path 35, and from the lower outlet port 36 to the lower portion in the water trough 2, Then, the water enters into the tank 4 that communicates with the water tub 2. Therefore, it has a soft finishing effect on the laundry, after which "drainage" is performed, "dehydration" is further performed, and the operation is terminated.

As described above, according to this embodiment, the softening finishing agent (treatment agent) can be surely charged into the tank 4 at the time of the final "rinsing" required. Further, in that configuration, the treatment agent is added to the tank 4 A charging path 35 corresponding to the fourth chamber in the conventional charging device, which is finally supplied, is provided in the tank 4 separately from the charging device 18, so that the charging device 18 has a chamber corresponding to that. Since it is possible to reduce the number of chambers inside the throwing device 18 as compared with the conventional throwing device, a place where the soft finish agent adheres, in other words, a place where cleaning is performed to remove the adhered soft finish agent. Can be reduced and the cleaning can be made easier. Further, the charging passage 35 is formed by a groove that opens toward the inside of the tank 4, and the opening portion 35a is covered by the charging device 18 attached to the tank 4, so that the charging device 18 is removed. If removed, it is considered that the degree of adhesion of the soft finish agent is high because it receives the soft finish agent discharged from the feeder 18 by the centrifugal force generated by the rotation of the tank 4 from the open portion 35a which appears immediately. It is possible to easily and desirably clean the inner surface of the throwing path 35, and also to easily remove dust, lint, etc., which tend to adhere to the inner surface of the throwing passage 35, so that the entire apparatus can be easily cleaned. can do.

In addition to the above, particularly in the above embodiment, the injector 18
Since the lower part 18a and the upper part 18b are simply fitted together, the manufacturability can be improved, and even with such a structure, the inside of the throwing device 18 can be used when the tank 4 is subjected to centrifugal dehydration. Since the second chamber 20 in which there is a risk of leakage of the softening agent discharged and transferred by means of the above is provided integrally with the upper part 18b of the container, the liquid leakage can be prevented. Furthermore, since the lower part 18a of the charging device 18, particularly the lower part 18a, is made of a transparent material, it is possible to easily judge the adhesion state of the softening agent and confirm the cleaning, and in addition, the charging device 18 is exclusively used for the wall surface part of the tank 4. Since the balance ring 11 is mounted on the balance ring 11, it is possible to avoid denting the balance ring 11 as much as possible, and it is possible to ensure good vibration damping performance by the balance ring 11.

However, the present invention is not limited to the embodiment described above and shown in the drawings. Therefore, the injector 18 may be constructed in a structure other than the above, and the lower part 18 of the injector 18 can be constructed.
a may be made of non-transparent material, and
May be provided on the tank 4 by being applied to the balance ring 11 or mounted on the balance ring 11, and may be appropriately modified and implemented within a range not departing from the gist.
