Abstract

PURPOSE:To improve the convenience of use by providing a pulsator rotating number control means to wash the clothes of various quality by either a pulsator for full automatic washing machine or a pulsator for non-full automatic washing machine. CONSTITUTION:In a non-full automatic tank 2 provided parallelly to a full- automatic tank 1, a bearing 17 is fixed on the bottom part and a pulsator 18 is supported to this bearing. The rotating number of a pulsator 7 is decelerated to 110-rpm by a reduction gear integrated into a clutch 10. On the other hand, the rotating number of the pulsator 18 is set to 300rpm according to the ratio of a diameter of a seep, around which belts 22 of a slave pulley 19 and a driving pulley 21 are wound. The ON/OFF time limit of the two pulsators 7 and 18 is controlled by the microcomputer of an operation part. Since the full automatic tank 1 and the non-full automatic tank 2 are parallelly provided, simultaneous washing, etc., can be executed to separate wash colored objects and white objects at the same time.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a washing machine in which a fully automatic washing tank and a non-fully automatic washing tank are installed side by side, and more specifically, the present invention relates to a washing machine in which a fully automatic washing tank and a non-fully automatic washing tank are installed side by side. This invention relates to a rotation control device for a pulsator on a non-automatic washing tank side.

[Conventional technology]

Fully automatic washing tanks, i.e., fully automatic washing tanks that automatically perform all processes of water supply, washing, drainage, rinsing, and dehydration (hereinafter referred to as fully automatic washing tanks), and non-fully automatic washing tanks, i.e., excluding the dewatering process. For example, Japanese Patent Publication No. 63-66232 discloses a washing machine that is equipped with a non-fully automatic washing tank (hereinafter referred to as a non-fully automatic tank) that performs the processes of water supply, washing, drainage, and rinsing individually or automatically. proposed earlier.

However, since the washing machine adopting the above configuration has a fully automatic tank and a non-fully automatic tank installed side by side, it is possible to wash colored items and white items separately and at the same time. You can wash the items at the same time or wash them first in the non-automatic tank side.
After washing, the items to be washed are transferred to the fully automatic tank for rinsing and dehydration, and during this time, the washing liquid and rinsing liquid in the non-automatic tank are reused for the next wash, which has the advantage of being able to perform so-called forward washing. be.

By the way, as mentioned above, among the conventional washing machines of this type that have a fully automatic tank and a non-fully automatic tank installed side by side, the ones that were commercialized for a while in the past have a pulsator that controls the washing action in the fully automatic tank. The rotation speed of the pulsator was the same as that of the pulsator that controls the cleaning action in the non-fully automatic tank.

[Problem to be solved by the invention]

However, when the pulsator on the fully automatic tank side and the pulsator on the non-fully automatic tank side are set to the same rotation speed, it is difficult to use the pulsator for clothing that has become more diverse in recent years, especially women's lingerie and clothing that easily loses its shape. is insufficient in terms of generating so-called soft water flow for delicate clothing such as woolen sweaters.

In other words, a conventional washing machine with a fully automatic tank and a non-automatic tank installed side by side can wash everything from stiff work clothes and jeans to delicate lingerie and wool sweaters.
As a method for washing a wide variety of clothes, the rotation speed of the pulsators in both tanks is the same, and the ON-OF
It is conceivable to use a means of changing only the time limit for F.

According to the above-mentioned precepts, it is possible to handle stiff clothing and general clothing, but for delicate clothing, even if the pulsator is turned on for a short period of time, the The reality is that the impact force on the fabric increases, making it impossible to obtain the desired effect.For example, when washing a sweater made of wool, the size of the sweater shrinks.

In this way, in a conventional washing machine that has a fully automatic tank and a non-fully automatic tank installed side by side, even if it has two washing tanks,
Looking at the quality of the clothes, there was a drawback in that delicate clothes could not be washed separately from stiff or regular clothes.

When looking at the quality of the clothes, the disadvantage of not being able to wash delicate clothes separately from stiff or regular clothes is the same for the washing machines that are currently mainstream, that is, washing machines with a single washing tank. That can be said. In other words, a washing machine with a single washing tank can handle stiff or general clothing, but for delicate clothing, shortening the on-time of the pulsator will basically not work. The reality is that the impact force on clothing increases, making it impossible to obtain the desired effect.

The purpose of the present invention is to provide a washing machine with a fully automatic tank and a non-fully automatic tank installed side by side, regardless of the case of a washing machine with a single washing tank.
In other words, it is possible to wash colored items and white items separately and at the same time, so-called simultaneous washing, or to wash the items to be washed first in the non-automatic tank side, and then wash the finished items in the fully automatic tank side. We focused on the quality of clothes in a washing machine that has the advantage of being able to carry out rinsing and dehydration, during which time the washing liquid and rinsing liquid are reused in a non-automatic tank for the next wash. The purpose of the present invention is to provide a washing machine of this kind that is easier to use than conventional ones and can separate stiff or ordinary clothes such as lingerie and woolen sweaters using a soft stream of water. ．． [Means for solving the problem] The above purpose is to create a fully automatic washing tank that automatically performs the entire process of water supply, washing, floating water, rinsing, and dehydration, and a fully automatic washing tank that automatically performs the entire process of water supply, washing, water drainage, and dehydration, and a system that independently performs the steps of water supply, washing, drainage, and rinsing. Alternatively, in a washing machine that has a pulsator that is installed in parallel with a non-fully automatic washing tank and each has a pulsator driven by an independent motor, either the fully automatic washing tank pulsator or the non-fully automatic washing tank pulsator is used. This is achieved by providing a pulsator rotation speed control means that allows washing of all types of clothes of different quality.

In other words, the present invention provides control that makes the rotational speed of the pulsator on the washing tank side of either a fully automatic washing tank or a non-fully automatic washing tank different from the rotational speed of the pulsator on the other washing tank side. It is characterized by having a means.

[Effect]

According to the present invention including the control means, it is possible to prevent the stiffness from being caused by one of the fully automatic and non-automatic tanks installed in parallel, that is, the washing tank with a higher rotational speed of the pulsator. Wash washed and general clothing. In addition, delicate clothing such as lingerie and woolen sweaters can be washed with a soft stream of water using the other washing tank, that is, the washing tank with a lower rotational speed of the pulsator.

18 is a diagram showing the ON10FF time period of the fully automatic washing tank pulsator and the non-fully automatic washing tank pulsator.

In Fig. 2 showing the appearance of the washing machine of the present invention, 1 is a fully automatic tank that automatically performs a series of processes from fetal fluid → washing → floating water → dehydration → water supply → rinsing → wandering water → dehydration; This is a non-fully automatic tank that performs each process of washing, draining, and rinsing individually or automatically, and the fully automatic tank 1 and the non-fully automatic tank 2 are placed side by side on a base 3. There is.

Reference numeral 4 indicates an outer frame surrounding the two tanks 1 and 2, and reference numeral 5 indicates an operation panel 5 placed above the outer frame 4.

As shown in FIG. 1, the fully automatic tank 1 is elastically suspended by a plurality of hanging rods 6, and a pulsator (1) 7 is rotatably supported at the bottom of the tank. The fully automatic tank 1 is rotatable by a clutch 10 fixed to the bottom of an outer tank 9 surrounding the inner tank 8. It is pivoted on. Moreover, a balancer l1 is fixed above the inner tank 8 to suppress imbalance during dehydration, and a liquid 12 is sealed inside the balancer l1. On the other hand, Clutch 10

A bearing 17 is fixed to the bottom of the non-fully automatic tank 2 installed in parallel with the fully automatic tank 1, and a pulsator (2) 18 is pivotally supported on the bearing 17. Further, a driven pulley (2) 19 is pivotally supported below the bearing work 7, and this driven pulley (2) 19 is pivoted above the motor (2) 20 supported on the base 3 in a vibration-proof manner. Drive pulley (2) 21 and belt (2) 22
It is connected through the , and is driven during washing and rinsing.

Furthermore, a part of the corner of the non-fully automatic tank 2 is covered with the overflow port 23.
is provided, and the water overflow port 23 performs overflow during water injection and rinsing.

On the base 3, there is also an internal drain hose (1) 25, which is installed at the bottom of the outer tank 9 of the fully automatic tank 1 and is connected to a drain valve (1) 24 that opens and closes the valve electrically. A Y-shaped pipe 28 is fixed to join the two hoses, the internal drainage hose (2) 27 connected to the drain valve (2) 2G provided at the bottom of the non-fully automatic tank 2, and this Y-shaped pipe 28 is connected to an external drainage hose 29 for draining water to the outside of the machine.

In the above configuration, the rotation speed of the pulsator (1) 7 is
110r due to the reduction gear built into the clutch 10
pm, and on the other hand, the rotation speed of the pulsator (2) 18 is reduced by the driven pulley (2) 19 and the driving pulley (2) 2
The speed is set to 300 rpm depending on the ratio of the sheave diameters around which belt (2) 22 of 1 is wound. The OFF time of the two pulsators (1) 7, (2) 180 is controlled by a microcomputer in the operating section shown at 30 in FIG. 3, and rotates forward and reverse in a time cycle as shown in FIG. return.

Here, the operation of the washing machine having the above structure will be explained.

First, put cloth in fully automatic tank 1 and start operation. The operation proceeds according to the steps shown in FIG.

However, as mentioned above, in the washing machine to which the present invention is applied, the fully automatic tank and the non-fully automatic tank 2 are installed side by side, so that it is possible to wash colored items and white items separately and in a timely manner. Simultaneous washing that allows you to wash the same items, and washing items in a non-fully automatic tank 2
The washed items are first washed on the side, and the washed items are transferred to the fully automatic tank side for rinsing → dehydration. During this time, the non-fully automatic tank 2
It has the advantage of being able to reuse the washing and rinsing liquid for the next wash.

However, in this type of washing machine commercialized in the past, as mentioned above, the rotation speed of the pulsator (1) 7 that controls the washing action in the fully automatic tank 1 and the washing action in the non-fully automatic tank 2 are different. Since the rotation speed of the pulsator (2) 18, which controls the It is impossible to wash the fabric without causing dimensional shrinkage or major damage to the fabric.

However, according to this embodiment, stiff work clothes, jeans, and judo uniforms are removed by powerful water jets (in addition,
According to experiments, delicate clothes such as lingerie and woolen sweaters were washed in the fully automatic tank 1 while washing at a speed of 250 to 350 rpm (in order to enhance the cleaning effect and prevent fabric damage). It can be washed with a soft stream of water (according to experiments, 100 = 15 Orpm was appropriate in order to increase the cleaning effect and prevent fabric damage), and from a qualitative standpoint, it is possible to wash a wide variety of clothes at the same time. Washing becomes possible.

In addition, the items to be washed are first washed in the non-fully automatic tank 2 side, and the washed items are transferred to the fully automatic tank 1 side for rinsing and dehydration, and during this time, the washing liquid in the non-fully automatic tank 2 is reused. When performing the next washing, so-called feed-washing, the standard water flow is selected from among the water flows preset in stages on the fully automatic tank 1 side as the agitation force for the fully automatic tank 1 used for rinsing. A moderate stirring force is sufficient, and there is no need to worry about insufficient rinsing.

In addition, as shown in this example, when the rotation speed of the pulsator (2) 8 on the side of the non-fully automatic tank 2 is made high and the rotation speed of the pulsator (1) 7 on the side of the fully automatic tank 1 is made low, the The rotation speed reduction mechanism on the automatic tank machine side (i.e., when rotating the pulsator (1) 7 during washing and rinsing, and on the other hand, when rotating the fully automatic tank 1 during dewatering, the rotation speed of the pulsator (1) 7 and the fully automatic tank Since a rotation reduction mechanism on the side of the non-fully automatic tank 2 is not required in addition to the rotation reduction mechanism (which makes the rotation speed of the tank 1 variable), the manufacturing cost of the product can be reduced accordingly.

〔Effect of the invention〕

The present invention is as described above, and as is clear from the explanation of the illustrated embodiment, the present invention has a fully automatic tank and a non-fully automatic tank installed side by side, and a pulsator driven by an independent motor. A washing machine that can wash colored items and white items separately and at the same time.
So-called simultaneous washing, in which the items to be washed are washed first in the non-fully automatic tank side, the washed items are transferred to the fully automatic tank side for dewatering, and during this time, the washing liquid and rinse are carried out in the non-fully automatic tank. In a washing machine that has the advantage of being able to perform so-called feed-washing, in which the liquid is reused for the next wash, all clothes of different quality can be washed using either the fully automatic washing tank pulsator or the non-fully automatic washing tank pulsator. In other words, by providing a pulsator rotation speed control means that controls the rotation speed of the pulsator on the washing tank side of either the fully automatic washing tank or the non-fully automatic washing tank, and the rotation speed of the pulsator on the remaining washing tank side. By providing a control means to differentiate between the fully automatic and non-automatic tanks installed in parallel, one of the washing tanks, that is, the washing tank with a higher rotation speed of the pulsator, removes stiff clothes. This machine washes general clothes, and also washes delicate clothes such as lingerie and woolen sweaters with a soft stream of water in the other washing tank, that is, the washing tank with a lower pulsator rotation speed. According to the invention, when focusing on the quality of clothing, it is easier to use than before by allowing delicate clothing such as lingerie and wool sweaters to be washed separately with soft water jets, as opposed to stiff or ordinary clothing. We can provide this type of washing machine with good quality.
