Description

Detailed Description of the Invention The present invention is a centrifugal dehydration type comprising a dehydration cage and a water receiving tank in which the dehydration basket is rotatably installed, and rinsing is performed by supplying water into the dehydration basket and rotating the dehydration basket. The present invention relates to a rinsing device.

Conventionally, there is a system that increases the rinsing effect of laundry by alternately performing spin-drying operation and water supply operation, but in this case, when the spin-drying operation is stopped and water is supplied into the spinner basket, a large amount of water is added to the laundry. Because of this, the next time the dewatering tank starts up, the balance state may be affected (shifting, it may hit the side wall of the water tank, or abnormal vibrations may occur, and as a result, the dewatering tank may not reach its normal rotation speed, and the motor may become unstable). The problem was that it caused a rise in temperature.

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

In the figure, 1 is an outer casing, 2 is a water receiving tank provided in the outer casing 1, and a dewatering cup 3 is rotatably installed inside the tank.

Reference numeral 4 indicates a large number of drainage holes provided on the circumferential wall of the dewatering basket 30, and reference numeral 5 indicates a motor that is vibration-proofly supported in the lower part of the outer casing 1 by a suspension 6. 8. The dewatering water is transmitted to the dehydration valve 3 via the coupling 9.

10 is provided in the middle of the dehydration shaft 8, and an oil seal 1
1 and a buffer rubber having a bearing 12, 13 a drain port formed at the bottom of the water tank 2, 14 a drain hose connected to the drain port 13, and 15 located at the rear of the upper part of the water tank 2. One end of a water supply hose 16 is connected to this water supply nozzle 15, and the other end of the water supply hose 16 is connected to a water tap 17.

Reference numeral 18 denotes a panel section that houses a time switch and the like.

Reference numeral 19 denotes a balance weight attached around the upper end opening of the dehydration basket 3. A press-fit lip 20 is arranged on the inner circumference side of the dehydration basket 3, and a claw portion 21 is formed on the outer circumference side.
1 is fixed to the dewatering basket 3 by engaging with the hook portion 21.

23 is a reinforcing ring formed to protrude above the balance weight 19; 24 is a rounded water puddle formed on the outer periphery of the balance weight 19; 25 is a water puddle located at the bottom of the water puddle 24; 24 and has a drain guide 26 below, and a plurality of drain ports are provided.

27 is welded and fixed to the outer periphery of the water puddle portion 24, and the water puddle portion 2
4, the outer peripheral end is continuous with the distribution part 28 whose outer peripheral end is welded and fixed to the outer peripheral end of the water reservoir part 24, and the inner peripheral end of this distribution part 28, and becomes smaller in diameter toward the bottom. Partition rib 29
It becomes more.

The operation in the above configuration will be explained.

First, the laundry is put into the dewatering basket 3, and the motor 5 is energized to perform dewatering.

Then, the dewatering basket 3 is stopped, and water is supplied from the water supply hose 16 into the dehydration basket 3 through the water supply nozzle 15.

At this time, a part of the supplied water is supplied into the water reservoir 24 along the outer peripheral side wall of the reinforcing ring 23.

When the water level of the supplied water becomes higher than the lower end of the partition rib 29, the water level supplied to the water reservoir section 24 is kept constant due to the air pressure sealed between the partition plate 27 and the excess water is Water overflows into the water tank 2 from above the partition plate 27.

In this case, the water drain port 2 provided at the bottom of the water reservoir 24
Although water leaks a little more than 5, the effect of the fluid balancer can be prevented by appropriately setting the number of drain ports 25 and the inner diameter size.

Furthermore, if the water supplied into the dewatering basket 3 overflows over the upper end of the reinforcing ring 23, the water is also supplied into the water reservoir 24, so there is no need to consider the spouting position of the water supply nozzle 15. During the cycle, it is possible to reliably replenish the water reservoir 24 with a constant amount of water.

After the water supply is finished, the motor 5 is energized to perform dehydration, but in this case, since the laundry contains a large amount of water that was supplied while the dehydration basket 3 was stopped, when the dehydration basket 3 is started, This will result in a very unstable condition.

However, the water in the water reservoir 24 provided on the outer periphery of the balance weight 19 is pushed up to the side wall by centrifugal force and flows, exerting the effect of a fluid balancer, causing the unstable dewatering basket 3 to become unstable at the start of dewatering. Adjust the balance.

In this case, if the design is such that the water pushed up to the outer periphery of the side wall of the water reservoir 24 by centrifugal force is always located above the upper end of the drain port 25, the water in the water reservoir 24 will be reduced during dewatering operation. The balance state can be adjusted by always maintaining a constant amount of water.

After the dewatering is completed, the water remaining in the water reservoir 24 passes along the inner circumferential wall of the dehydrating basket 3 and is directly discharged into the water receiving tank 2 from the drain guide 26 without coming into contact with the laundry.

Therefore, there is no risk of residual water freezing during the winter.

Note that in the above embodiment, one water supply nozzle 15
However, as shown in FIG. 2, a water supply nozzle 15' that supplies water only to the water reservoir 24 is provided separately, and the water supply nozzle 15
Even if water is supplied only to the dewatering basket 3, the same effects as in the above embodiment can be obtained.

As is clear from the above embodiments, according to the present invention, water is supplied to the water pool of the balance weight attached above the dewatering corner when water is supplied. Since water exerts the effect of a fluid balancer, it is possible to reliably prevent unbalance when starting the dewatering process, and therefore the start of the dehydrating corner becomes smooth, and as a result, the conventional problem of causing a rise in motor temperature can be avoided. It disappears.
