摘要
The present invention relates to a no-load discrimination method using a temperature sensor of a cold / hot water purifier. In particular, when the temperature reaches a target temperature set by a microcomputer capable of temperature control, the control unit controls the control and checks whether there is water in the temperature rise curve. It is related to the prevention of fire risk due to temperature rise by sensing;Hot water tank GT with a heating body G is installed so that the hot water or cold water is supplied to the purified water tank T having the water detection sensor H detecting the water from raw water D, and the cooling body L. Control board (CP) comprising an input unit (I) capable of inputting temperature, a control unit (C) for controlling input and output, and a microcomputer unit (M) for detecting a temperature increase. The microcomputer starts the on / off command process to the control unit (10) when the power supply (20) is supplied to the heating element (G) and the cooling element (L). The Y value 40 obtained by subtracting the temperature is obtained. If the predetermined time has not elapsed, the power supply of the heating body (G) and the cooling body (L) is turned on again, and if the Y value (40) is added to or subtracted from the initial temperature at the initial temperature, the power is larger than the predetermined temperature (50). After the predetermined time has elapsed, the heater 60 supplies power to the heating body G and the cooling body L. If the Y value is smaller than the predetermined temperature, the current temperature becomes the target temperature 70 and the power supply 80 is turned off. The present temperature is equal to the set temperature 90 and power is supplied to the heating body G and the cooling body L. If the current temperature is not the same as the target temperature 70, the heating body G and the cooling body L. Apply power. Therefore, the presence or absence of water is determined by using the temperature rise and fall characteristics of the hot water and cold water parts, and controlled according to the state to prevent ashes caused by rapid temperature rise in advance and to remove the unnecessary energy so that it is properly controlled only when there is water. It is an invention provided with an effect.
