The reference voltage is input to the inverting input terminal (- terminal) of the comparator U2 of the summer comparison unit 18 and the voltage of the drinking water When the voltage due to the sensing temperature is inputted to the non-inverting input terminal (+ terminal) of the comparator U2 of the summer comparator 18 via the summer voltage regulating unit 17, the non-inverting input terminal And the voltage input to the non-inverting input terminal (+ terminal) is less than 800 mv, the comparator U2 outputs a high signal.

The driving signal output unit 14 is connected to the second terminal and the first terminal of the switch JB by a high signal outputted from the summer comparator 18 and receives a driving signal of the compressor 6 The transistor Q1 is disconnected and the current does not flow into the resistor R7 and the inductor K1-B and the switch K1-A of the driver 16 is turned off because the inductor K1- An alternating current for driving the compressor 6 flows and the compressor 6 is driven while the three terminals and the five terminals are connected.

The switch JB of the drive signal output unit 14 is brought into contact with the second terminal and the first terminal by the high signal in the comparator U2 of the summer comparator 18 to drive the compressor 6, (4) to cool the drinking water.

That is, when the temperature of the drinking water in the cold water tank 4 is equal to or higher than 8 캜, the compressor 6 is driven to circulate the refrigerant in the instant cooling system and heat exchange is performed with the drinking water in the evaporator and the cold water tank 4, It gets cool enough to be good.

The resistor R2 and the resistor R1 of the summer comparator 18 divide the power supplied to the comparator U2 as a voltage divider circuit using two resistors and the voltage input to the resistor R2 is divided by a voltage source And the voltage between the resistor R2 and the resistor R1 becomes the reference voltage input to the comparator U2 as a divided voltage.

The partial pressure ratio of the divided voltage and the divided voltage in the summer comparator 18 is proportional to the ratio of the resistor R2 to the resistor R1 and the divided voltage is as follows.

 V3 = (1+ (R2 / R1)) V4

Here, V3 is the reference voltage of the comparator U2, and V4 is the voltage to be divided.

A signal input to each of the comparator U1 and the summer comparator U2 of the winter comparison section in order to maintain a high level in the logic circuits of the winter comparison section 13 and the summer comparison section 18 is plotted floating state is not high level and not low level. Therefore, the system becomes unstable due to side effects such as oscillation, high power consumption, noise, and the like. When the switch JB is turned on, a low state is normally input. When the switch JB is off, a pull-up resistor R17 , R5) were used.

The pull-up resistors R17 and R5 make the voltage applied to the switch JB close to the power source when the output terminals of the comparators U1 and U2 are connected

That is, since the input impedance is extremely high, the current flows less and the voltage drop in the resistor hardly occurs due to a small current flow.

The display unit 19 is further connected to the winter driving circuit and the summer driving circuit and the display unit 19 is connected to the switch J9 separately and the light emitting diodes D8 and D9, When the compressor 6 is driven, the red LED emits light, and if the compressor 6 is not driven, the red diode is caused to emit light, thereby allowing the user to recognize whether the compressor 6 is driven.

The emission color or the display method of the light emitting diodes D8 and D9 depending on whether the compressor 6 is driven is not limited to the above method and can be changed as much as possible.

Therefore, the present invention is effective in that the compressor for cooling the drinking water is not driven during the winter season, so that energy of the winter season is saved and the drinking water of the winter season is not subcooled, so that the drinking water can be easily consumed and the cold water can be consumed even in the summer season .
