Description

[Detailed explanation of the idea] The present invention relates to a dehydrator having a dehydrating and rinsing function.

This type of dehydrator has a water sprinkling tube erected approximately in the center of the dehydrator, and by injecting water into the water sprinkling tube while rotating the dehydrator intermittently, water is sprayed onto the surrounding laundry. However, with this type, the water spray tube is fitted into a support tube fixed to the inner bottom of the dewatering tube, so the water spray tube is not surrounded by the support tube. There is a problem in that water is not sprayed at all from the bottom end of the water sprinkling tube, and as a result, water cannot sufficiently penetrate into the laundry stored in the water spinner, resulting in insufficient rinsing. Ta.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a dehydrator capable of sufficiently rinsing even the laundry stored in the dehydrator.

An embodiment in which the present invention is applied to a two-tub washing machine will be described below with reference to the drawings.

First, in FIG. 1, 1 is the outer box of the washing machine, 2 is a dewatering tank installed together with the washing tub 3 inside the outer box 1, and 4 is a dewatering cylinder installed inside the dehydrating tank 2. A large number of dehydration holes 5 are formed in the peripheral wall.

In FIG. 2, reference numeral 6 denotes a cylindrical support member, which is used to attach a water spray tube to be described later, and is fixed to the inner bottom of the dewatering tube 4 by screws or the like, and its outer periphery is A plurality of projections 7 are integrally provided.

Reference numeral 8 denotes a water spray tube, which is made of sintered resin having countless water-permeable micropores in its wall, and whose lower end is expanded in a substantially tapered shape to form an enlarged diameter portion 8a. ing.

Reference numeral 9 denotes a mounting tube part for attaching the water spray tube 8 to the support member 6, which is made of synthetic resin separately from the water spray tube 8, and has a bayonet engagement mechanism on the inner periphery as shown in FIG. A plurality of substantially inverted engagement grooves 10 are formed.

Such a mounting cylinder part 9 has seven flange 9 integrally extending on the outer periphery of the lower end.
a is fixed to the lower end of the water spray tube 8 by heat welding or the like,
In this fixed state, the mounting cylinder part 9 projects upward from the lower end of the water spray cylinder 8 inside the large diameter part 8a, and is surrounded by the peripheral wall of the large diameter part 8a via a predetermined space 11.

The water sprinkling tube 8 is removably installed in the dewatering tube 4 by fitting the mounting tube 9 to the outside of the support member 6 and engaging the engagement groove 10 with the protrusion 7. There is.

In FIG. 1, 12 and 13 are inner and outer lids for opening and closing the laundry entrance/exit 14 to the water spinner 4, and 15 is attached to the lower surface of the inner lid 12 so that the water inlet 15a faces into the water sprinkling barrel 8. It is a water injector.

Next, the operation of the above configuration will be explained.

To dehydrate and rinse the detergent-washed laundry, it is transferred from the washing tub 3 to the space surrounding the water sprinkling tube 8 in the dewatering capacity 4.

In this state, when water is injected into the water sprinkling cylinder 8 through the water injector 15 while the dewatering cylinder 4 is intermittently driven by a dewatering motor (not shown), water flowing out from the water inlet 15a is stored in the water sprinkling cylinder 8. Due to the water head and rotational centrifugal force, the water is vigorously discharged through the water-permeable micropores in the peripheral wall toward the surrounding laundry, and then passes through the laundry by centrifugal dewatering action, and finally through the small holes 5 of the dewatering cylinder 4. It is discharged into the dewatering tank 2.

According to this embodiment, the lower end portion of the water spray tube 8 is formed into a so-called double tube shape, and the mounting tube portion 9 corresponding to the inner tube is fitted and connected to the support member 6. The water supplied to the water spray tube 8 is also stored in the lower end large diameter portion 8a, that is, within the space 11, and is also released from the peripheral wall of the large diameter portion 8a. Unlike the conventional system in which water is not sprayed from the lower end at all, water is sprayed approximately evenly from the entire area between the upper and lower ends of the water spray tube 8.

Since the mounting cylinder part 9 is located within the large diameter part 8a of the water sprinkling cylinder 8, the lower end of the water sprinkling cylinder 8 comes to be located near the inner bottom of the dewatering cylinder 4 by fitting into the support member 6. A sufficient amount of water can penetrate into the laundry stored in the bottom of the dehydrator 4, as well as the laundry above it, and it can be rinsed thoroughly.

By the way, in the case of dehydration and rinsing by installing a water spray tube upright in the dewatering section, the diameter of the dewatering tube is increased to avoid a decrease in dewatering capacity due to the installation of the water spray tube.
In such a device, unless the balance of the dewatering cylinder is improved to reduce the amount of movement, the dewatering tank and the outer box must be enlarged, which is disadvantageous in terms of manufacturing and cost.

Regarding this point, in this embodiment, since the mounting tube part 9 is provided at the lower end of the water spray tube 8, the weight of the lower center of the dehydration tube 4 increases accordingly, and as a result, the overall center of gravity is also slightly lowered. As a result, the effect of correcting the uneven storage distribution of laundry is improved, and the excellent effect of suppressing the swinging movement of the dehydrator cylinder 4 is achieved.

Incidentally, the mounting cylinder portion 9 may be formed integrally with the water spray tube 8 by simultaneous molding, or the water spray tube may be, for example, a metal tube with a large number of small holes formed in its peripheral wall.

As explained above, in the present invention, the lower end of the water spray cylinder is formed into a double cylinder shape, and the inner cylinder part is fitted and connected to the support member provided at the inner bottom of the dewatering cylinder. A sufficient amount of water can permeate even the laundry stored at the bottom of the basket and it can be thoroughly rinsed, which is an extremely excellent practical effect.
