Description

How to rinse the washing machine

The present invention relates to a rinsing method of a washing machine. In particular, the rinsing method of the washing machine to maximize the rinsing effect by rinsing with a rinsing water temperature in which residual detergent and contaminants are separated from the laundry during rinsing after washing is completed. It is about.

In general, when washing with a washing machine, there is mainly washing with only cold water, while washing with both cold and hot water, and rinsing with cold water only in the case of rinsing, but adding rinsing frequency or shower rinsing to improve rinsing power. There is a case.

However, if the washing and rinsing water temperature is generally maintained at the same water temperature during washing and rinsing, the contamination adhered to the fiber during washing and rinsing is maintained while the bond between the fiber and the soil is relaxed while the fiber swells. As a result, contamination is no longer easily separated from the fibers and the rinsing degree is relatively low.

Therefore, when washing to increase the washing water temperature during washing, the solubility of detergents and contaminants increases, and the fiber swells a lot so that the washing solution is penetrated deeply while the washing solution is penetrated deeply.

As such, when rinsing in the state of infiltrating the washing solution, the rinsing water does not contain detergent, so the penetration power is insufficient. Since the wash can not be washed off, the rinsing effect is lowered.

Nevertheless, conventionally, the rinsing water temperature is rinsed at a low water temperature when rinsing rather than washing, and thus, the fiber sometimes has a problem of completing a series of washing administrations in a state in which washing liquids and contaminants remain.

The present invention aims to improve the rinsing effect by swelling the fibers by swelling the fiber at a higher rinsing water temperature than the washing water temperature when the rinsing after the completion of the washing process.

In order to realize the above object, the present invention provides a step of supplying cold and hot water during rinsing after completion of the washing stroke in the initialization state, and sensing the rinsing water temperature supplied in the step to reach a predetermined rinsing water temperature. And rinsing if the rinsing water temperature detected in the step reaches the rinsing water temperature arbitrarily set, and proceeding with rinsing while determining whether the rinsing is completed at the rinsing time set at random. It is characterized by.

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

First, power is supplied to the washing machine to wash the laundry, and then, while the laundry to be washed is put in the washing machine, the operation signal for the washing, rinsing, and dehydrating administration, which is a series of washing administrations, is input through the operation signal input unit. B), the microcomputer (b) goes to the water supply step 30 according to a predetermined program for the input washing administration signal and controls the water supply and drainage drive unit (c) to supply water to the washing tank 2. The water level to be started at this time is to proceed through the water supply while sensing through the water level sensor (6) of the water level detection unit (D).

When the water supply is completed while the water supply is in progress as described above, the microcomputer (b) goes to the washing step 31 and rotates the motor 5 forward and reverse through the motor driving part (e). The rotational force of the motor 5 is decelerated through the gear unit 4 to proceed with washing by the pulsator 3.

In this way, during the washing process, the microcomputer (b) goes to the washing completion determination step 32 to determine whether the washing in progress is completed and repeats the washing until the washing is completed. 33) go to the drainage control unit (c) to proceed with the drainage, and after the drainage is completed, the microcomputer (b) go to the cold, hot water supply stage (34) through the water supply and drainage unit (c) The valve (not shown) and the hot water valve (not shown) are controlled to supply cold and hot water to the washing tank 2.

While the hot water is supplied as described above, the microcomputer (b) goes to the water temperature sensing step 35 to supply water while sensing the water temperature through the water temperature sensor 7 of the water temperature sensing unit (bar), and then the microcomputer (B) Go to the water temperature determination step 36 to determine whether the detected water temperature reaches a randomly set water temperature of 40 ℃, the reason is that when the water temperature is above 40 ℃ shrinkage and In the case of clothing dyed by printing in the dyeing process with the fear of deformation, there is a problem that discoloration and fading occur, whereas, in the case of the temperature lower than that, as shown in Table 1, the purge course of the washing machine (14 minutes), the water level ( High water level), washing amount 10KG, and the number of tests three times each condition,

That is, when the rinsing water temperature is 40 ℃ or less, the water temperature was found to be lower than 40 ℃, while on the other hand, as the temperature rises to 40 ℃ swelling fibers and detergents and contaminants that penetrated between the fibers and fibers during washing When the rinse water temperature is 40 ° C. or more, the degree of washing increases, but in the case of fibers dyed with the printing, there is a risk of discoloration or fading, and the rinsing water temperature is 80 ° C. When reached, it was rather reduced.

Therefore, the rinse water temperature is set to 40 ° C. to determine the water temperature of the water supply. At this time, when the water temperature of the water supply is determined, if the detected water temperature does not reach a randomly set water temperature of 40 ° C., the hot water is continuously supplied. On the other hand, if the sensed water temperature reaches a randomly set water temperature of 40 ℃ the microcomputer (b) to control the water supply and drain drive (c) to stop the cold water and hot water supply, and then go to the rinsing step (37) motor drive unit ( E) controlling the rinsing with hot water while rotating the pulsator 3 forward and reverse through the motor 5 and the gear unit 4.

During the rinsing as described above, the microcomputer (b) goes to the rinsing completion determination step 38 to determine whether the rinsing in progress has reached a predetermined rinsing frequency. If not reached, the microcomputer (b) proceeds to the rinsing step 37 and rinses until the set rinsing frequency is reached. Then, if the rinsing frequency reaches the predetermined rinsing frequency, the rinsing is completed. Then go to this dehydration step 39 to control the motor drive (e) to dehydrate and complete the washing tank 2 at high speed to complete a series of washing administration.

As described above, according to the present invention, in a series of washing strokes, the rinsing process is performed by swelling the fibers at a rinsing water temperature relatively higher than the washing water temperature when the rinsing cycle is completed. Since the rinsing proceeds while rinsing, the rinsing will provide a cleaner and more hygienic rinsing power.
