The mode selection switch 140 may be configured to select a wash water supply mode to be one of a neutral mode, a heating mode, and a cooling mode.

In the neutral mode, the washing water of the first washing water storage tank 320 or the washing water of the second washing water storage tank 420 that has not been heated is sprayed as it is, or the outside air temperature sensed by the temperature sensor 130 The temperature of the wash water supplied to the spray tube 200 may be adjusted by comparing the temperature T3 of the reference temperature Ts with the temperature range T4 < Ts < T5 of the set reference temperature Ts.

In the heating mode and the cooling mode, the washing water heated or cooled by any one of the first washing water supplying unit 300 and the second washing water supplying unit 400 is supplied or cooled according to the washing water supplying mode set by the user . That is, in the heating mode and the cooling mode, the wash water is supplied based on the wash water supply mode selected by the user regardless of the outside temperature T3 sensed by the temperature sensor 130. Accordingly, The washing water supply mode can be arbitrarily selected.

In the above description, the temperature of the washing water supplied to the spray tube 200 is controlled by driving one of the first washing water supplying part 300 and the second washing water supplying part 400. However, The temperature of the washing water may be adjusted while the washing water 300 and the second washing water supply unit 400 are simultaneously driven and the washing water is mixed and supplied. In this case, there is an advantage that the supply flow rate of the washing water can be increased.

As described above, in the present invention, in consideration of the ambient temperature, the washing water is heated and supplied in a low temperature environment, and the washing water is coolly supplied in a high temperature environment. In the spring / autumn season, By supplying the washing water of the storage tank as it is, the washing water supply mode can be arbitrarily selected in accordance with the user's constitution, thereby improving the usability of the hand washer.
