Description

[Detailed Description of the Invention] The present invention relates to a dewatering cap for a centrifugal dehydrator that can reliably perform water rinsing and also has a water saving effect.

Conventionally, in a centrifugal dehydrator, in order to maximize its water-saving effect, after washing and before rinsing, the laundry is placed in a centrifugal dehydrator basket (hereinafter simply referred to as a dehydrator), and after water is supplied, the dehydrator is opened. There is a so-called dehydration rinsing method that uses high-speed rotation to dilute the detergent.

It is well known that in this dehydration rinsing system, a dehydration cap b provided with a plurality of holes a as shown in FIG. 5 has been conventionally used for the purpose of increasing the dilution effect. If there are many items to be washed in the dehydrating basket with only the extraction hole a, the items to be washed will come into close contact with the dehydration cap b, blocking the extraction hole a, making it impossible to sufficiently moisten the items in the deicing basket. Another drawback is that a large amount of water is wasted.

Therefore, as shown in Fig. 6, some dehydration caps have a structure in which ribs C are erected on the underside of the dehydration cap b to prevent them from coming into close contact with the laundry, but some have a structure in which the extraction hole a provided in the dehydration cap b is small. If so, a large amount of water would be wasted if the amount of water supplied was large, and if a large extraction hole a was provided, there was a risk that part of the laundry would come out during dewatering, which was dangerous. .

The present invention eliminates the above-mentioned conventional drawbacks, and embodiments thereof will be described below with reference to the accompanying drawings.

In Figures 1 to 4, 1 is an outer tank, 2 is a water receiving tank provided in the outer tank 1, and a dewatering cylinder 3 is installed inside, and this dehydrating cylinder 3 is connected to a motor (not shown). and rotates by rotating the motor.

A cover plate 4 placed and fixed on the water receiving tank 2 facing the upper part of the dewatering cylinder 3 has a through hole 4a in the center and is provided with an inner cover 5 which can be opened and closed.

Furthermore, a dewatering cylinder 6 that can be opened and closed is provided on the top of the cover plate 4.

Reference numeral 7 denotes a switch stand placed and fixed on the upper part of the water receiving tank 2, and has a dewatering timer 8 inside.

A curled portion 3a is provided at the upper opening end of the dehydration tube 3, and the dehydration cap 9 is inscribed inside the opening end through the curled portion 3a to facilitate attachment and detachment. In addition, it is made of a synthetic resin material that is highly flexible and bendable.

The outer frame portion of the dehydration cap 9 is bordered with a convex portion 10 that fits into the curled portion 3a of the upper opening of the dehydration cylinder 3, and the dehydration camp 9 is circular and detachable from the dehydration cylinder 3. Since it is difficult to do so, a pair of circular fleshy parts are cut out to make it roughly oval-shaped.

A notch 10a is formed in a portion of the convex portion 10 in the non-circular portion 9a to facilitate attachment and detachment.

Further, in order to easily attach and detach the dehydrating cap 9, a handle 11 is protruded from the center of the dehydrating cap 9.

Furthermore, as shown in FIGS. 2 and 3, the water injection surface of the dehydration cap 9 is provided with a recess 14 having a substantially truncated conical cross-sectional shape in a circular, arcuate, or radial manner, and A plurality of punch holes 15 are provided in the slope portion of this truncated cone, as shown in FIG. 4 (4).

The punch hole 15 may be formed by cutting out a part of the bottom of the truncated cone as shown in FIG. 4(B).

Here, the water for dehydration rinsing is supplied from the water supply hose 12.
, through the water supply port 13 and the extraction hole 15 of the dehydration cap 9,
Water is supplied into the dehydration cylinder 3.

As described above, according to the present invention, a substantially truncated conical recess is formed in the substantially flat plate portion near the center of the dehydration cap in a circular, arc-shaped, or circular shape.
Alternatively, a plurality of rows are arranged radially and holes are provided in the slopes of the recesses, and the unevenness caused by the approximately truncated cone-shaped recess and the other flat plate parts can be used even when there are many items to be washed in the dewatering basket. Since a space is created between the dehydration cap and the laundry, even when a large amount of water is supplied, this recess becomes multiple rows of pockets to store the water. The water is evenly injected into the space through the vent hole without wasting water, and as a result, the laundry is well moistened, which not only saves water but also saves money. Dehydration and rinsing can be performed.

In addition, since the approximately truncated cone-shaped recess also serves as a rib,
The wall thickness of the dehydration cap can be made thinner, and as a result,
Since the amount of molding material can be reduced, excellent economical effects can be achieved.
