The purpose of the present invention is to automatically control the temperature of washing water sprayed onto the hand in response to the external temperature to allow washing water to have a pleasant temperature, or control the temperature of washing water in accordance to a water supply mode selected by a user. To achieve this purpose, the present invention comprises: a main body (100, 1000) including a hand input port (110, 1100), a sensor (120, 1200) to sense whether or not the hand enters the hand input port (110, 1100) and a mode selection switch (140) to select any one of a heating mode and a cooling mode as a water supply mode a spray nozzle (210, 2100) to spray washing water into the hand input port (110, 1100) a first washing water supply unit (300, 3000) including a heater (350, 3500) to heat the washing water supplied to the spray nozzle such that the temperature of the washing water is a first target temperature (T1), and then supplying the heated washing water a second washing water supply unit (400, 4000) including a cooler (450, 4500) to cool the washing water supplied to the spray nozzle such that the temperature of the washing water is a second target temperature (T2), and then supplying the cooled washing water and a controller (500) to control the washing water to be heated or cooled by any one of the first washing water supply unit (300, 3000) and the second washing water supply unit (400, 4000) in accordance to the washing water supply mode selected by the mode selection switch (140) and then be supplied to the spay nozzle (210, 2100).COPYRIGHT KIPO 2015본 발명은 손에 분사되는 세척수의 온도를 외기온도에 대응하여 쾌적한 온도 상태가 되도록 자동으로 조절하거나, 사용자가 선택한 세척수 공급 모드에 따라 조절하여 공급할 수 있는 핸드 워셔를 제공함에 그 목적이 있다. 이를 구현하기 위한 본 발명은, 손 투입구(110,1100)와, 그 내부로 손의 진입 여부를 감지하는 감지센서(120,1200)와, 세척수 공급 모드를 가열 모드와 냉각 모드 중 어느 하나로 선택하는 모드 선택 스위치(140)가 구비된 본체(100,1000) 상기 손 투입구(110,1100)의 내측으로 세척수를 분사하는 분사노즐(210,2100) 상기 분사노즐(210,2100)로 공급되는 세척수의 온도가 제1목표온도(T1)가 되도록 가열시켜 공급하는 가열부(350,3500)를 구비한 제1세척
