Description

Detergent Dissolution Method of Washing Machine

In general, a washing machine may be washed with only cold water, and may be washed with both cold and hot water. In addition, a washing machine may be added to a washing machine while washing cold water by heating.

Therefore, in the case of the washing machine for cold water, the water temperature of the washing water to be supplied is relatively low, so that the detergent introduced during washing does not dissolve well, and thus, undissolved detergent may be caught or remains between the laundry. Water can be supplied while maintaining a predetermined water temperature with respect to the water temperature of the washing water to be watered, but when the water supply level is completed at a predetermined predetermined water level, washing is performed as it is even if the water temperature of the water supply is lowered, and detergent It was a problem to completely dissolve the water, and in the case of the washing machine equipped with the heating device, because the water temperature and water level of the wash water to be supplied is continuously heated until the water level and water temperature reaches a predetermined water level and water temperature You can dissolve the detergent that is added together when the washing water temperature reaches the predetermined temperature Since only washing is performed without heating, the washing proceeds without heating even though the water temperature is lowered during washing, so that the undissolved detergent remains.

The present invention is intended to prevent the dissolution of the detergent to be added during the water supply and to prevent the undissolved detergent remaining in the laundry, in order to realize this in a state in which the heater is mounted in the water storage tank of the washing machine, the water after supplying to a very low water level to the heater Heat and wash, but heat washing while judging whether the predetermined water temperature has been reached, and when the predetermined water temperature is reached, stop the heat washing and detect the quantity of water to determine the water level. Detect the water temperature of the water and washing the heat while judging whether the detected water temperature is lower than the predetermined predetermined temperature, and if the detected water temperature is not lower than the predetermined predetermined temperature, it is determined whether the determined water level has been reached. Characterized in that to be made.
