Abstract

PURPOSE:To carry out the cleaning for the outer periphery of an inner tank which is used for washing and dehydration and is accommodated inside an outer tank, effectively and sufficiently. CONSTITUTION:A direction change part 11 where the water jetted from the inside of an inner tank 5 is direction-changed toward the outer surface of the inner tank by the revolution of the inner tank 5 is formed on the inner surface of the outer tank 2, and the whole periphery of the outer surface of the inner tank 5 is applied with the water hammer due to the water which is direction- changed, and cleaning is carried out effectively.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dehydrating and washing machine capable of washing the outer surface of an inner tub.

[0002]

2. Description of the Related Art Conventionally, in a washing machine for combined use of dehydration,
It has an outer tub and an inner tub, stores water in both tubs for washing, and spins the inner tub for dehydration.

However, in the case of this one, although the outer surface of the inner tank is in a state where dirt is attached by washing,
Generally out of reach and cannot be washed. As a result, dirt accumulates on the surface, mold grows, or an offensive odor is generated. Furthermore, the accumulated dirt sometimes separates from the outer surface of the inner tub and enters the inner tub. There was a problem that it adhered to.

Therefore, there is provided a special course for cleaning the outer surface of the inner tank by filling the outer tank with water and rotating the inner tank in the water.

[0005]

However, the above-mentioned one has a problem that the outer surface of the inner tank cannot be sufficiently cleaned only by rotating the inner tank in water.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a washing machine for combined use of dehydration, which is capable of sufficiently cleaning the outer surface of the inner tub.

[0007]

In order to achieve the above object, in a washing machine for combined use of dehydration according to the present invention, water spouted from the inside of the inner tub by the rotation of the inner tub is provided on the inner surface of the outer tub. Is provided with a turning portion for turning toward the outer surface of the.

[0008]

According to the above means, the water ejected from the inside of the inner tank by the rotation of the inner tank is diverted by hitting the turning portion of the inner surface of the outer tank and hitting the outer surface of the inner tank, so that the entire outer surface of the inner tank is completely covered. A water hammer can be applied to the lap to effectively perform cleaning.

[0009]

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

First, FIG. 3 shows an outer casing 1 of the entire washing machine for both dehydration and use.
The outer tub 2 is supported and arranged by the elastic suspension mechanism 3 in the inside. Inside the outer tub 2, an inner tub 5 having a large number of dehydration holes 4 on its peripheral side is rotatably arranged, and inside the inner tub 5, a stirring member 6 is arranged at the bottom. There is.

A drainage valve 7 and a drainage hose 8 are provided mainly at the outer lower portion of the outer tub 2, and a drive mechanism 10 having a motor 9 as a main component is also provided.
With 0, the inner tank 5 is stopped at the time of washing and rinsing to rotate the stirring body 6, and the inner tank 5 is rotated together with the stirring body 6 at the time of dehydration.

The inner surface of the outer tub 2 has a structure as shown in FIGS.
As shown in FIG. 5, the turning portion 11 is formed by a plurality of substantially vertically extending step portions.

A top cover 12 is mounted on the outer box 1, a control device 13 composed of, for example, a microcomputer is arranged inside the front part of the outer cover 1, and an inner tank 5 is formed inside the rear part.
A water supply valve 14 for supplying water is provided inside.

Now, in the case of the above-mentioned configuration,
As described above, the inner tub 5 is rotated by the drive mechanism 10 during dewatering, and the rotation causes the water contained in the laundry to be ejected from the inner tub 5 through the dewatering holes 4 to perform the required dewatering. At this time, the jetted water hits the turning portion 11 on the inner surface of the outer tank and is turned toward the inner tank 5 as shown by the arrow in FIG. By hitting the outer surface, a water hammer is given to the entire outer surface of the inner tank 5 to effectively wash the inner tank 5.

As described above, in this structure, the water ejected from the inside of the inner tank 5 by the rotation of the inner tank 5 is turned by the turning portion 11 on the inner surface of the outer tank 2 and applied to the outer surface of the inner tank 5. By this, a water hammer can be applied to the entire circumference of the outer surface of the inner tank 5 to effectively clean the outer surface of the inner tank 5, which is sufficient compared to the conventional one in which the inner tank is rotated in water. A good cleaning effect can be obtained.

Further, particularly in the case of the above-mentioned structure, the outer surface of the inner tub 5 is not cleaned specially, but also when it is dehydrated, so that it is automatically effective every time the washing machine is operated. Can be cleaned easily, and therefore user management,
The outer surface of the inner tank 5 can always be kept clean without the need for troublesome operations.

However, the present invention is not limited to the embodiment described above and shown in the drawings. Therefore, the cleaning of the outer surface of the inner tank 5 is performed while supplying water into the inner tank 5 separately from the dehydration operation. It may be performed by rotating the inner tank 5,
Moreover, the rotation may be performed in a state of being rotated by inertia instead of by driving, and may be appropriately changed and implemented without departing from the scope of the invention.

[0018]

As is clear from the above description, the washing machine for combined use of dehydration according to the present invention has an outer tub and an inner tub, and water is stored in the both tubs for washing and the inner tub is rotated. Thus, in the one for dehydration, a turning portion is provided on the inner surface of the outer tank to divert water ejected from the inner tank by the rotation of the inner tank toward the outer surface of the inner tank. By this, a water hammer caused by the water jetted from the inside of the inner tank and turned around can be applied to the entire circumference of the outer surface of the inner tank to effectively perform the cleaning, and the outer surface of the inner tank can be cleaned. It has the excellent effect that
