- the method of supplying condensed water generated during drying of clothes to the filter is largely divided into a method using potential energy and a method using a pump.
- Korean Patent Registration No. 10-1410595 As a method of using a fall, there is Korean Patent Registration No. 10-1410595. This is a method in which the condensed water generated during drying is moved to the drain tank located on the upper part of the drum, and then the water in the drain tank is drained with a filter or heat exchanger when the filter needs to be cleaned.
- the problem is that whether to wash the filter or the heat exchanger and the degree of cleaning are determined according to the amount of condensed water generated during drying. In other words, in both methods, it is the process of determining whether the amount of condensate required for cleaning the filter or heat exchanger (cleaner compliance level) has accumulated. Since the method of washing the filter or the heat exchanger only with the condensed water, conventional laundry treatment plants have a problem in that the filter or the heat exchanger cannot be sufficiently washed if the amount of condensed water is small.
- the present disclosure is to supplement the heat exchanger washing water, which can be worn out depending on the situation, through direct water introduced into the washing machine to ensure a sufficient amount of cleaning at all times. .
- the present disclosure can easily implement drainage through a drain hole provided in the drying device, and through this, the residual water in the dryer can always be completely removed, thereby blocking hygiene and odor problems caused by the proliferation of microorganisms. do.
