Description

[Detailed Description of the Invention] In a conventional two-tub washing machine, the laundry is first washed in the washing tub, then the laundry is transferred to the spin-drying basket for spin-drying, and then the laundry is transferred to the washing tub again. A common rinsing method was to rotate a pulsator while supplying water.

However, recently, a method has been proposed in which a structure is constructed so that water can be supplied into the dehydration basket during dehydration, and rinsing is performed while dehydration is being performed.

This method is widely used because it requires only a small amount of water and can be easily rinsed, and is easy to use.

Furthermore, as an even more user-friendly method, a system has been proposed in which dehydration and rinsing is performed by automatically repeating the cycle of water supply, stirring, drainage, and water several times using a timer. Water is supplied immediately, and since the dehydration basket is still rotating due to inertia during this water supply, the supplied water is immediately sprinkled over the dehydration cap and out of the dehydration basket. The rinsing efficiency was unsatisfactory because the water was not effectively entering the dewatering basket.

The present invention has been made to solve the above problems, and one embodiment thereof will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes the main body of the dehydrating and rinsing type washing machine, and 2 a washing tub installed in the main body 1, which is integrally molded with a dehydrating tub 3 from resin.

Reference numeral 4 denotes a pulsator installed at the inner bottom of the washing tub 2, which is rotationally driven by the washing motor 5.

Reference numeral 6 denotes a dehydration basket rotatably installed in the dehydration tank 3, and is rotationally driven by a dehydration motor 7.

Reference numeral 8 denotes a panel section installed at the rear of the upper part of the main body 1, which houses electrical components such as a time switch.

Reference numeral 9 denotes a dewatering tray cover that is removably installed at the top opening of the dehydrating tank 3; 10 denotes a dehydrating inner lid that can be opened and closed at the top of the dehydrating tray cover 9; It is made of transparent material so that you can see the inside.

Reference numeral 11 denotes a dehydration outer lid, and a transparent plate 12 is provided in the center so that the inside of the dehydration basket 6 can be seen.

Reference numeral 13 denotes a ring-shaped water supply nozzle disposed on the lower surface of the dehydration receiver cover 9. As shown in FIGS. A nozzle hole 14 is formed.

Reference numeral 15 denotes a water supply solenoid valve installed in the panel portion T, and this water supply solenoid valve 15 is connected to the water supply nozzle 13 via a water supply hose 16.
is connected to.

Reference numeral 17 denotes a dehydration cap that is detachably attached to the inside of the dehydration basket 6 and has a plurality of holes 18 formed therein.

Reference numeral 19 denotes a flange formed on the outer periphery of the upper end opening of the dewatering basket 6, and this flange 19 constitutes a curled portion.

Reference numeral 20 denotes a friction plate fixed to the lower surface of the water supply nozzle 13, and this friction plate 20 comes into contact with the outer peripheral flange 19 of the upper end opening of the dewatering basket 6 during water supply.

Further, the water supply nozzle 13 is normally contracted as shown in FIG. 2a.

The operation in the above configuration will be explained.

Water from the water supply solenoid valve 15 flows into the water supply nozzle 13 via the water supply hose 16.

Since the water supply nozzle 13 is made up of an elastic bellows, the pressure of the water flowing into the water supply nozzle 13 causes the friction plate 20 fixed to the lower surface of the water supply nozzle 13 to expand as shown in FIG. The movement of the dewatering basket 6 is restricted by coming into contact with the outer periphery flange 19 of the upper end opening of the dehydrating basket 6.

Thereby, the water that has flowed into the water supply nozzle 13 is ejected from the multiple nozzle holes 14 and is reliably supplied into the dewatering basket 6.

Therefore, all of the supplied water passes through the laundry in the spin-drying basket 6, so the rinsing efficiency is significantly improved.

As described above, according to the present invention, a telescopic ring-shaped water supply nozzle is provided above the dehydration basket, and the lower surface of the water supply nozzle is brought into contact with the outer periphery flange of the upper end opening of the dehydration basket when water is supplied. Because of this, the water sprayed from the water supply nozzle can be reliably supplied into the dehydration basket.
As a result, all of the supplied water passes through the laundry in the spin-drying basket, making it possible to significantly improve rinsing efficiency.
