Description

Detergent Dissolution Method of Washing Machine

The present invention relates to a detergent dissolving method of a washing machine, and in particular, to improve the washing power during washing, so that the detergent to be dissolved is not dissolved so that the undissolved detergent does not remain after washing the laundry, due to the undissolved detergent It relates to a detergent dissolving method of the washing machine to prevent damage or deterioration.

In general, the washing force, that is, the degree of washing in the washing machine, the difference occurs due to the shape of the pulsator, the intensity of the water flow, the time of the water flow, the shape of the water flow, etc., in particular, the difference is caused by the detergent added.

Therefore, in the case of the detergent, in order to improve the washing effect, the dissolution of the detergent first reaches the saturation solution at the beginning of washing, and then the chemical action, the pulsator's rotational motion, and the water flow must be performed together.

Therefore, since most of the detergents to be added are concentrated detergents, the initial dissolution of the detergent is very important when washing.

However, in the conventional detergent dissolving method, the washing machine is put together with water supply from the detergent at the time of washing, or the user starts washing while stirring the pulsator after manually adding the detergent.

Therefore, when the detergent is partially dissolved (unsaturated solution), it is often buried in the laundry or remains in the washing tank. In the case of the colored clothes, the chemical action of the detergent causes the color to be blurred or refluxed to damage the clothes. I had side effects.

The present invention is a detergent that is added during washing does not become an unsaturated solution state, so that the washing is made while being dissolved in a saturated state, to prevent the detergent from being undissolved or undissolved detergent remaining between the laundry during washing. By doing so, it is intended to prevent damage or deterioration of the laundry (clothing) due to the remaining detergent.

In order to achieve the above object, the present invention comprises the steps of dispensing the detergent through the detergent box with water in the initial state, and then the detergent is added and rotated forward and reverse, and dissolving the detergent while injecting air bubbles; When the water supply is completed, it is determined to determine whether the water supply is completed while dissolving the detergent in the step, characterized in that made to stop the water supply and proceed with the washing.

TABLE 1

Referring to the operation of the present invention made as described above are as follows.

First, when the power is supplied to the washing machine and the detergent according to the amount of laundry to be washed is put in a detergent box (not shown), the driving signal input unit (A) inputs the washing operation signal for a series of washing administrations through the microcomputer. (B) In the initialization state, go to the water level determination step (30) to control the motor driving part (e) to detect the amount of washing put into the pulsator (4), forward and reverse rotation, and determine the water supply level according to the detected washing amount Done.

When the water level determination is completed as described above, the microcomputer (b) goes to the water supply and detergent input step 31 and controls the water supply and drainage drive unit (c) to proceed with water supply to the determined water level in the washing tank 3 through the detergent box. In addition, the detergent put into the detergent box is primarily dissolved by physical potential energy while falling into the washing tank 3 together with the wash water being supplied.

Subsequently, in the state in which the detergent is first dissolved with the water supply, the microcomputer (b) goes to the pulsator forward and reverse rotation step 32 to control the motor driving part (e) while intermittently rotating the pulsator forward and reverse. In addition to dissolving the introduced detergent with the rotating water flow in the forward and reverse directions, the microcomputer (b) goes to the air bubble generating step 33 and controls the air bubble generator 8 through the air bubble generating part (bar). Injecting air bubbles into the rotating water flow in the forward and reverse rotation, while generating air bubbles while turning on and off for 1 minute to dissolve the unsaturated detergent in a saturated state by the impact of the air bubbles burst.

In the state of dissolving the detergent into the detergent injected into the pulsator forward, reverse rotation and the impact of bursting air bubbles and the potential energy of the wash water being supplied, the microcomputer (b) in the water supply completion determination step ( Go to 34) to control the water level detection unit (D) to detect the water level supplied through the water level sensor (7) to determine whether the detected water level reaches the water supply level determined according to the washing amount, and the determination result If the water supply is not completed at the determined water level, water is repeatedly performed from the water supply and detergent input step 31 until the water supply is completed at the determined water level, while if the water supply is completed, the water supply and drainage driver (C) To stop the water supply and control the motor driving part (e) to proceed with washing while the pulsator 4 is rotated forward and backward at a predetermined interval, Meanwhile, the air bubble generator (bar) is controlled to generate air to the air bubble generator 8 while the washing proceeds.

Thus, the conductivity of the wash water after completing a series of washing strokes while dissolving detergent and the conductivity of the wash water after completing a series of washing strokes while dissolving detergent in the past, as shown in Table 1 above, water level: high water level , Water temperature: 30 ℃, Washing course: Purge, Detergent: When measured with conductivity meter under high density super tie (1g / l) condition, detergent is added manually, pulsator is rotated forward and reverse, and air bubble is injected. In case of washing, 889 ㎲ before washing and 913 후 after washing, the detergent was added together with the washing water and the pulsator was rotated forward and reverse and air bubbles were injected. The test result was 892 ㎲, and when detergent was manually added and only the pulsator was rotated forward and reverse, it was 839 9 and 923 후 after washing.

Therefore, when the detergent is put together with the wash water supplied through the detergent box, the pulsator is intermittently rotated, and the air is injected to dissolve the detergent. You can see that the detergent was dissolved well.

As described above, in the present invention, the detergent is introduced through the detergent box together with the water supply in the initialization state, and then the detergent is added and rotated forward and backward, and the air is injected into the air to dissolve the detergent while dissolving the detergent. After the laundry is completed, the detergent is undissolved after the completion of the washing to prevent the detergent remaining undissolved between the laundry, to prevent damage or deterioration in the laundry (clothing) due to the remaining detergent. .
