Description

Washing and rinsing method of permeation type washing machine using centrifugal force

The present invention relates to a method of washing and rinsing a permeation type washing machine using centrifugal force, and more particularly, to control the number of revolutions of a washing tank to reduce the occurrence of large noise or foam while allowing a smooth washing to be performed even with a small pump. And a rinsing method.

Permeation type washing machine using the centrifugal force proposed to solve the entangled problems, such as entanglement, kinky, porosity, etc., which is a conventional problem of a pulsator washing machine, which is commonly used, as shown in FIG. An inner tank 2 is provided, a nozzle 4 for spraying the washing liquid into the washing inner tank 2 is provided at the center upper portion of the inner tank 2, and the washing inner tank 2 is disposed below the outer tank 1. A motor (5) for rotating the engine is installed, and the tax solution is introduced into the tank (6) through the tax solution supply passage (3) on the lower surface of the outer tub (1), and then installed on one side of the tank (6). The driving of the pump (7) to be supplied to the nozzle 4 of the upper through the liquid supply flow passage 3, the drainage pipe (9) having a drain valve (8) is connected to the other side of the water tank (6) It is. In the permeation type washing machine using the centrifugal force configured as described above, the driving force of the motor 5 is rotated along the tax solution supply passage 3 by the pump 7 while the inner tank 2 is rotated through the nozzle 4. By the centrifugal force is injected with a constant spraying force to the laundry side biased to the wall surface of the inner tank (2), as a result the washing is made by using the washing liquid as the tax solution is transmitted through the laundry. Therefore, it is possible to prevent entanglement, kinking and foam damage, which are problems of the pulsator washing machine, and to reduce washing quantity and detergent amount, and to simplify the driving unit, thereby increasing efficiency and reducing power consumption by reducing the load on the motor. There are several advantages.

In the permeation type washing machine using the centrifugal force, the flow rate of the washing liquid sprayed from the nozzle is 30 L / min. When the abnormality is over, the inherent rotational speed of the washing tub which is excellent in washing performance is present, and 40 L / min. Efficient washing is achieved only by using the ideal pump. However, in this case, since the injection flow rate is too large, the noise of the moment when the liquid is injected from the nozzle hits the laundry is about 60 dB, so it is shielded. There is a technical difficulty in eliminating this because the amount of foam generated when the washing liquid sprayed from the nozzle is passed through the laundry or falling freely dropping in the tank.

Accordingly, an object of the present invention is to provide a washing method capable of efficiently washing even a small-capacity pump by controlling the number of revolutions of the washing tank to reduce the occurrence of the noise and foam.

The present invention is a laundry tank containing laundry, a tank that can hold a certain amount of washing, a pump that can pump up the washing liquid from the tank, and the washing and rinsing of the permeation type washing machine using a centrifugal force consisting of a nozzle for spraying the washing liquid to the laundry. In the method, there is provided a washing and rinsing method of a permeation type washing machine using centrifugal force having a plurality of washing tank revolutions.

Figure 2 shows the change in the cleaning power according to the number of revolutions of the washing tank, Figure 3 schematically shows the flow of the washing liquid in the laundry in the washing machine according to the present invention.

FIG. 2 shows that the difference in washing power between washing at low rotation speed and washing at high rotational speed is about 2% if washing only at a single rotation speed after washing the laundry well at a low frequency of about 100 rpm. Shows low. On the other hand, if considering the impact noise generated by the foaming side or the injection of the laundry hit the laundry will not be able to exceed the rotation speed of the washing tank 500rpm.

The reason why the washing performance is almost no difference when washing only a single rotation speed is that once the laundry is put in the washing tank and the inner tank is rotated, the laundry is biased to the inner tank wall so that the entire laundry maintains a constant shape. The washing liquid flows to the area where washing liquor tends to flow, such as the gap between laundry with small density or between washings, so when the washing tank rotates at a certain speed, the position where the washing liquor passes is constant so that the effect of improving the washing power is not obvious. do.

At this time, the position of the laundry is determined by the tangential speed, normal speed, gravity acceleration and centrifugal force as physical factors.

Therefore, if the washing tank rotation speed is single and the rotation speed is changed for each washing, the washing speed increases and the washing performance is slightly improved due to the centrifugal force, but it is extremely insignificant. You can't raise it without limit.

However, in the case of washing while changing the rotation speed every minute without making the rotation speed constant, the position where the tax solution flows changes because the permeation speed, permeation resistance, etc. of the normal direction and the tangential direction change according to the rotation speed change. Since the tax solution can pass evenly between the laundry, the washing performance is improved and the washing deviation is reduced.

Therefore, as shown in Table 1, the washing liquid is sufficiently wetted with the laundry at a low rotational speed of about 100 rpm at the initial stage of washing, and the water is rotated at the first high rpm (200), and lowered again to the low rotational speed to make the laundry sufficiently wet again. And raising the first or second high rpm (300) to have a different flow of the tax solution from the first high rpm so as to evenly wet the laundry to the laundry, and to lower the washing speed again. Try to run it repeatedly.

At this time, by operating the pulsator in the middle of the laundry to the shape different from the previous to the washing tank so that the washing in the laundry, if possible to evenly wet the washing solution improves the effect of the washing well.

In addition, in the centrifugal washing machine, the process of removing contaminants that do not pass through the laundry must be removed from the laundry. At this time, the washing process of the conventional washing method (pulsator, spiral winding pulsator, drum method, etc.) is entered. Rotating at a low rotational speed allows the laundry to contain the tax liquor and then supplies additional water to remove the dirt that cannot pass through the laundry. In this way, the laundry is supplied with a sufficient amount of detergent, and the excess water for flowing the laundry is between the laundry, so that a large amount of detergent is embedded in the laundry compared to the conventional method, thereby improving laundry performance.

On the other hand, when the time is not sprayed at a high rotational speed can be made to break the bubbles between the inner tank and the outer tank by the rotation of the inner tank.

If the laundry is unevenly placed in the washing tank and the vibration of the inner tank is severe when washing at high rotation speed, additional water is supplied to finish the general washing stroke for the remaining washing time.

On the other hand, the control of the number of revolutions in advance to input the time of repeating the low and high rotation speed, or as shown in Figure 1 to install the water level sensor 10 in the tank as shown in Figure 1 to rotate the rotation speed of the inner tank The water sensor 11 can be provided and performed.

In the latter case, when the washing tank is rotated at a low rotational speed, the washing liquid is evenly wetted to the laundry, and the washing liquid is almost collected in the washing tank, so the amount of washing liquid in the water tank 6 is reduced, which is detected by the water level sensor 10. When the rotation speed of the washing tank is increased to a high rotation speed, the washing liquid in the laundry is discharged by centrifugal force, and the washing tank is rotated at a high rotation speed. When the foam fills between the inner and outer tanks, the rotation speed of the washing tank is dropped. ) Detects and lowers the speed of the washing tank to low speed so that this process can be done automatically.

Table 1 Washing and Rinsing Process of One Embodiment of the Invention

The use of a low capacity pump lowers the price of the pump, reduces noise and suppresses foaming. In addition, by doing this, when performing a full stroke of washing only with the existing pulsator method, the amount of washing can be improved to 45% or less (below 5%) than the existing (more than 30%). In addition, since the washing time using a pulsator, etc., only a fraction of the time can reduce the damage. In addition, since less water is used during rinsing, the time for water supply and drainage can be reduced by this time.
