Description

[Detailed description of the invention] [Industrial application field] The present invention relates to an electric washing machine.

[Conventional technology and its problems]

As is well known, a washing machine has rotary blades such as a pulsator or agitator installed at the bottom of a tank, and is rotated by a motor to create a whirlpool water flow in the water stored in the tank, thereby washing and rinsing. It is.

During washing and rinsing, frayed fabrics and lint are released from the items being washed, and the swirling water flow causes them to adhere to other items being washed. Various methods have been devised to dispose of such lint, such as filter-type ones, but in this method, an upward flow of water flowing from the bottom to the top inside the tank is intentionally created, and small lint, etc. are brought to the surface of the water. There are two ways to do this, such as letting it float in the water and draining it as is, or trapping it in a filter.

For example, one example is the one shown in Japanese Utility Model Publication No. 50-936, in which the rising water flow is obtained by the back action of a pulsator, which is expected especially during rinsing because it is full of water. You won't be able to get as much water flow as you did.

Furthermore, as disclosed in Japanese Utility Model Publication No. 51-41425, a holder for a water injection hose is installed vertically on the tank wall, and water from the hose is forced to flow into the center of the tank through the holder. However, since the water pressure of the water discharged from the holder is released at this point, an effective upward water flow cannot be obtained when the holder is full of water during rinsing.

The purpose of the present invention is to provide a method for operating a washing machine that eliminates the disadvantages of the conventional example and that can reliably and effectively obtain an upward flow of water, thereby allowing fine lint and detergent residue to quickly rise to the water surface and make it easier to drain them. Our goal is to provide the following.

[Means for solving problems]

In order to achieve the above object, the present invention stands up a shaft body with spiral blades formed on the outer periphery in the center of a pulsator provided at the bottom of the tank, and during rinsing, these pulsators and spiral blades are rotated in the opposite direction to the washing time. The gist of this is to obtain a water flow that descends and blows up around the tank.

[Effect]

According to the present invention, when rinsing, the pulsator and the spiral blade are rotated in the opposite direction to those during washing, and the fresh water near the water surface is pushed down by the spiral blade at the center of the tank, and then pushed out by the pulsator to the outside. The water pushed out by the pulsator is blown up around the tank, and as a result, fine lint and detergent residue rise to the water surface and are appropriately discharged from around the tank.

〔Example〕

Embodiments of the present invention will be described in detail below with reference to the drawings.

The figure is a longitudinal sectional front view of the main parts of an example of the washing machine used in the present invention, and (1) in the figure shows the washing tank.

A pulsator (3) is attached to the protruding end of a rotary shaft (2) in the tank that penetrates the bottom of the washing tank (1), and a washing motor (4) and a pulley are attached to the lower end of the rotating shaft (2) outside the tank.
■Connect using a transmission mechanism such as a belt.

This pulsator (3) has radial blades (3a) projecting downward, and has upper and lower water ports (3b).
was formed on the ceiling surface.

In the figure, (5) is provided parallel to the wall of the tank (1), and a large number of small holes (
5a), the lower end of which is curved to enter below the pulsator (3), and the end thereof forms a water inlet (6).

The space between the partition cover (5) and the tank (1) is a space for overflow treatment, and an overflow hose (1) using a telescopic pipe is installed here.
3) and connect it to a drain pipe, etc.

At the center of the pulsator (3) is a flexible spiral blade (screw blade) (7) made of flexible rubber or synthetic resin.
A shaft body (7b) having a) formed on the outer periphery is stood up, and a cylindrical cover (8b) with an open tip is attached to the outer periphery of the spiral blade (7a).
).

The diameter of the spiral blade (7a) is Φd, and the second cover (8b
), the relationship ΦD≧Φd is established.

The first cover (8a) and the second cover (8b) are connected to form a continuous cover (8) whose center rises as a cylinder and whose lower part widens in a saw-like shape. ) is fixed to the bottom of the tank (1) by the part of the first cover (8a), and the first cover (8a) as a hem end.
A water inlet (9) was formed between the end and the partition cover (5). Furthermore, the water inlet (9) is divided by a direction plate (10) attached at right angles between the cover (8a) and the partition cover (5).

The covers (8a) and (8b) are coated with fluorine or are molded using fluororesin in order to have a low coefficient of friction on their inner surfaces. Furthermore, the direction board (10)
, pulsator (3), etc. may be similarly applied.

A roof-like cylindrical cover (11) is attached to the upper opening of the second cover (8b), which is a cylindrical body. A water inlet (12) opens downward from the upper end of the cover (8b) all around the circumference.

Next, the method of the present invention using the above-mentioned washing machine will be explained.

Let us assume that water is stored in the washing tank (1) and that there is something to be washed in the water.

When the motor (4) is started, the pulsator (3) rotates via the rotating shaft (2), and the rotation of the pulsator (3) further rotates the shaft body (7b) and the spiral blade (7a).

Both of these rotate in the normal direction, and the water between the partition cover (5) and the tank (1) is sucked up from the water inlet (6) by the rotation of the pulsator (3), and some of the water is absorbed by the blades (3a) of the pulsator (3).
) and flows out into the tank (1) from the water inlet (9) as an ascending water flow, thereby pushing the items to be washed up and down and washing them.

Note that because of the first cover (8a), the items to be washed do not come into direct contact with the pulsator (3).

Further, a part of the water sucked up from the water inlet (6) passes through the water inlet (3b) of the pulsator (3), and is further moved along the water to the second cover by the lifting action of the spiral blade (7a). (8b) and is ejected from the water inlet (12) at the upper end over the entire circumference.

The water spouted out in this way falls downward in the tank (1),
Since water is sprayed onto the surface of the water, unnecessary foaming on the surface of the water is suppressed.

Next, when water is newly stored in the transfer tank (1) during rinsing, the motor (4) is reversed, thereby causing the pulsator (
3) and the spiral blade (7a) also rotate in the opposite direction to the washing time.

In the figure, α is the water level during washing, β is the water level during rinsing,
During rinsing, the water level is high and above the water inlet (12) at the upper end of the second cover (8b).

Therefore, by reversing the spiral blade (7a), the water inlet (1
2) The fresh water sucked in near the water surface is pushed downward through the cover (8b) at the center of the tank (1), passes through the water inlet (3b) of the pulsator (3), and is sent to the outside by the blades (3a). being pushed out.

The water pushed out by the pulsator (3) in this way is
An upward flow of water blows up from the bottom of the tank, lifting small lint and detergent residue from the water to the water surface.

Then, these are connected to the overflow hose (1
3) is discharged to the outside.

In addition, such a pulsator (3) and a spiral blade (7a
) may be performed only in part of the rinsing process.

〔Effect of the invention〕

As described above, the operating method of the washing machine of the present invention reliably and effectively obtains a rising water flow during rinsing, which allows fine lint and detergent residue to quickly rise to the water surface, improving washing efficiency. It is something that can improve.

As a result, the rinsing time is shortened, and the time required for washing the items to be washed is also shortened, which prevents fabric damage and deformation.
