In the cold water supply step (S1), the control unit 90 first turns on the cold water valve (S1).

The cold water supplied from the outside of the tap water when the cold water valve is turned on is gradually supplied to the inside of the tub 10, and the temperature sensor 88 detects the temperature of the supplied cold water and outputs it to the controller 90.

The hot water supply step (S2) (S3) (S4) is to supply hot water if the temperature of the cold water supplied in the cold water supply step (S1) is outside the rinse set temperature range (for example, 25 ℃ ~ 35 ℃) The temperature of the water is adjusted within the rinse set temperature range (for example, 25 ° C to 35 ° C).

The hot water supply step (S2) (S3) (S4), including a temperature comparison process (S2), a hot water valve on process (S3), and a temperature recomparison process (S4), hereinafter, the hot water supply Steps S2, S3, and S4 will be described in detail.

First, the controller 90 performs a temperature comparison process to check whether the temperature of the cold water detected by the temperature sensor 88 is within a rinse set temperature range (for example, 25 ° C. to 35 ° C.) (S2).

Here, the rinse set temperature range is a temperature range set to exhibit an optimal rinsing performance and is set by an experiment or the like.

The controller 90 determines that the detected cold water temperature is outside the rinse set temperature range (eg, 25 ° C. to 35 ° C.), that is, the cold water temperature is the lower limit temperature of the rinse set temperature range (eg, 25 ° C.). If it is determined to be lower than), to turn on the hot water valve for water supply (S3).

Hereinafter, a description will be given of turning off the cold water valve when the hot water valve is turned on.

When the hot water valve is turned on, hot water supplied from outside such as a boiler or hot water is supplied into the tub 10 and mixed with cold water, and the water temperature in the tub 10 is increased by mixing hot water.

Here, the hot water valve may be turned off after being turned on for a preset time (for example, 30 seconds), or may be kept on until a separate off signal is input.

The temperature sensor 88 detects the temperature of the water risen by the hot water supply and outputs it to the controller 90, and the controller 90 provides an optimum rinse reference temperature (eg, 30 ° C.) Compare again (S4)

Herein, the optimum rinse reference temperature (for example, 30 ° C) is a temperature exhibiting optimal rinsing performance, particularly in the rinse set temperature range (for example, 25 ° C to 35 ° C). It is used as a reference temperature value for determining whether the hot water valve is off.

As a result of the comparison, if the temperature of the elevated water is less than the optimum rinse reference temperature (eg, 30 ° C.), the controller 90 determines that the temperature suitable for rinsing has not been reached and repeats the on-off of the hot water valve S3. Or continue (S3)

On the other hand, if the temperature of the elevated water is above the optimum rinse reference temperature (eg, 30 ° C.), since the temperature of the water has risen appropriately for rinsing, turn on the cold water valve again to minimize the use of hot water.

When the cold water valve is turned on, the cold water is additionally supplied to the inside of the tub 10 and mixed with the water whose temperature is raised by the hot water supply.

The controller 90 may continuously turn on the hot water valve when the cold water valve is turned on again, and may turn off the hot water valve.

If the hot water valve is continuously turned on when the cold water valve is turned on again, the temperature of the water may be higher than the upper limit temperature (for example, 35 ° C.) of the rinse set temperature range, and the rinsing performance may be lowered. Since the usage-amount becomes large, it is preferable to turn off a hot water valve.

On the other hand, after the control unit 90 turns on the cold water valve again (S5), if the water temperature in the tub 20 is outside the rinse set temperature range (for example, 25 ° C to 35 ° C), the hot water feed water Steps S2, S3 and S4 and cold water resupply step S5 are repeated to adjust the temperature of the water in the tub 20 to the rinse set temperature range.

On the other hand, the controller 90 does not turn on the hot water valve if the detected temperature of the cold water is within the rinse set temperature range (for example, 25 ° C to 35 ° C) as a result of the temperature comparison process S2. To turn on the cold water valve.

On the other hand, the water level sensor 86 detects the water level in the tub 10 when the water supply as described above, and outputs to the control unit 90, the control unit 90 performs the rinsing step, when the water level reaches the rinsing level. (S6) (S7)

That is, the controller 90 turns off the water supply valve 41 and drives the motor 30 to rotate the drum 20 so that rinsing may proceed.

When the drum 20 rotates, the fabric inside the drum 20 is tumbled inside the drum 20 to act with water in a rinse set temperature range (for example, 25 ° C to 35 ° C), and the rinsing force is increased. .
