Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a one-tank dehydrating and washing machine, and particularly relates to a structure in which water is supplied to a dehydration and washing tank, and the dehydration and washing tank is rotated to perform rinsing and dewatering.

Conventional column configuration and its problems Conventionally, in this type of single-tank dehydration washing machine, after washing, draining and dehydration are performed, then water is supplied, the water is stored in the dehydration and washing tank, and the water is stirred, and then the water is drained (dewatered). In order to repeat the process, rinsing was performed by rinsing. Therefore, the rinsing process does not start until water has accumulated in the tank, and when the water supply is low, it takes time for the water to accumulate, which has the drawback that the overall washing time inevitably increases.

Additionally, with the recent trend of larger washing machines, the tank itself has also become larger, making this drawback an even bigger problem.

At the same time, rinsing by storing a large amount of water in a large tank was a waste of money from a water-saving perspective, and a structure that allowed rinsing to be performed using a small amount of water was desired.

OBJECTS OF THE INVENTION The present invention solves the conventional problems and provides a one-tank dehydration washing machine that improves the rinsing effect, reduces the amount of water used, and shortens the time required for the process.

Structure of the Invention In order to achieve the object of "2.1", the present invention provides a water supply means for supplying water to the inner surface of the upper side wall of the dehydrating dishwashing tank;
A motor for driving the dehydrating dish washing tank is provided, and the motor is intermittently energized to perform dewatering and rinsing while changing the rotational speed of the dehydrating dish washing tank. The water from Shosha provides an excellent rinsing effect.

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of the present invention will be described based on the accessory chair and the drawings.

In the figure, reference numeral 1 denotes a dehydrating dishwashing tank having a plurality of through holes 1a in its side wall, and has an agitator 2 at the center of the bottom that reciprocates from side to side. 3 is a washing shaft to which the agitator 2 is connected. Reference numeral 4 denotes a receiving tank in which a dehydrating dish washing tank 1 is installed, and the washing water is discharged to the outside of the machine via a cock 5 and a drain hose 6. 7 is an autobalancer attached to the upper end of the dehydration and sump tank 1. Reference numeral 8 denotes a dehydration receiving cover attached to the upper part of the receiving tank 4, which prevents water from scattering during dehydration. 9 is a water inlet spout that communicates with the water supply via the water supply valve 10, and the water inlet surface is connected to the dehydrating dishwasher 41#.
It faces the inner surface of the upper side wall of 1. Reference numeral 4a denotes a tank reinforcing plate installed at the bottom of the tank 4, which has a spherical seat 4b, and suspends and supports the tank l'fj4 on the outer casing 12 via a support rod 11 and a suspension (not shown). . A motor 13 transmits rotation to a pulley 15 via a V-belt 14. 16 is a rotation transmission mechanism section.

In the above configuration, the operation will be explained after washing, draining,
After dewatering, normally the power to the motor 13 is turned off and at the same time the rotation of the dewatering tank 1 is stopped using a brake, but this is not done and only the power to the motor 13 is turned off. As a result, the rotation speed of the dehydrating dish washing tank 1 gradually decreases due to the inertia of high-speed rotation during dehydration, and when the rotation speed drops to 200 rpm or less, the water supply valve 10
, and supply water through the water inlet spout 9. At this time, since the water injection surface of the water injection spout 9 faces the inner surface of the upper side wall of the tank 1, the supplied water is directly supplied to the items to be washed that are pressed against the side wall of the tank 1. Therefore, the supplied water penetrates into the fabric without wasting it, and compared to the conventional water supply to the center of tank 1, the water penetrates into the fabric better, increasing the rinsing effect and using less water. It will be possible soon.

Next, the motor 13 is energized and the dehydrating dish washing tank 1 is turned on.
When the rotation speed reaches around 200 rpm, the motor 13 is turned off, and the dehydration dish washing tank 1 is rotated by inertia, and the rotation speed of the dehydration dish washing tank 1 reaches 5 orp.
When the object falls near m, the motor 13 is energized again.

The rotation of the dehydrating dish washing tank 1 was set to the aforementioned 20 rpm, which is the maximum rotation speed at which the supplied water does not become 5 ounces of water and scatter when it hits the rotating washing item. Because there is. Also, the minimum rotation speed is 60 r
The reason for setting it as pm is as follows. Dehydration dish washing tank 1
If the water supply is completely stopped, the water will be supplied to only one part of the item to be washed, and some parts of the item will absorb water and become heavy, resulting in an imbalance. In this state, motor 1
3, there is a risk that the entire suspended mechanism will shake significantly and hit the outer casing 12. Therefore, by constantly rotating the dehydrating dishwashing tank 1 at a rotational speed of 5 Orpm, water is evenly supplied to the items to be washed.

By repeating the above intermittent operation, dehydration and rinsing can be performed. The relationship between the rotational speed of the dehydrating dishwashing tank 1 and the process of the sukiyaki cycle is as shown in FIG.

Here, dehydration rinsing will be explained in detail.

The water supplied to the items to be washed during inert rotation is shown in Figure 2 (A).
As shown in the figure, gravity allows it to penetrate evenly throughout the item being washed. Next, the infiltrated water is placed in the dehydrating dish washing tank 1 at 200 rpm.
It passes through the items to be washed and flies out of the tank at a rotational speed of about m. At this time, the detergent components contained in the items to be washed are simultaneously discharged out of the tank along with the water, and the items to be washed are rinsed.

Even if it drops to around 50 rpm! If there is no blue operation and the tank is constantly rotating at high speed, as shown in Figure 2 (B), it is difficult for water to penetrate the entire object to be washed, and the water supplied to the top of the object to be washed is immediately drained. Only the upper part of the item to be washed passes through and comes out of the dehydrating dishwashing tank 1, leaving the lower part of the item to be washed unrinsed. That is, 20 Orpm
By having a process in which the rotation of the dehydrating dishwashing tank 1 is lowered from 5 to 50 rpm, the water permeates all the items to be washed, and the items to be washed are rinsed uniformly.

Since washing can be performed in the manner described above, there is no need for time for water supply as in the past, and there is no difference in water supply time due to the size of the water supply flow rate, and the water supply time itself is eliminated, making it possible to shorten the time for washing. This point is
Figure 4 (A) shows the conventional program shown in K, and Figure 4 (B)
This is clear when compared with the IZIJ program shown in the following. Furthermore, since rinsing requires considerably less water than conventional rinsing, the water saving effect can be enhanced.

In addition, in the conventional method, dewatering is applied after the water has been drained, and the brakes are applied after the dehydration is completed, but in this embodiment, the brakes are not applied and coasting is performed, so the number of times the brakes are applied is reduced. There is one less cycle per cycle, which improves brake durability.

In addition, in the embodiment, an agitation type washing machine using a substantially conical agitator was described, but the present invention can also be implemented in a washing machine using a pulsator to obtain the same effect as the present embodiment. .

Effects of the Invention As is clear from the above embodiments, the single-tank dehydrating washing machine of the present invention can shorten the time required for the entire washing process, and at the same time save the amount of water used for washing. It permeates evenly, and furthermore, the permeated water can be reliably dehydrated along with the ingredients, resulting in an extremely good rinsing effect.
