Embodiment Construction

[0018] The present invention will be further described below in conjunction with drawings and embodiments.

[0019] Such as figure 1 The illustrated embodiment is as follows: a temperature control circuit for a water dispenser.

[0020] The live wire L of the power supply is connected to the neutral wire N of the power supply through the power switch T, the rectifier diode D1, the drop-down resistor R1, and the yellow indicator light Y-LED in turn. The yellow indicator lights up when the power switch T is turned on.

[0021] The power switch T is also connected to the incoming line terminal of the thermal protector KSD1, and the set temperature of the thermal protector KSD1 is 90°C. When the temperature inside the hot water tank reaches 90 degrees due to special reasons such as circuit failure, the thermal protector KSD1 will automatically disconnect and stop power supply. Like this except that the yellow light line has electricity and the yellow light is bright, other circ...

Abstract

The invention discloses a temperature regulation and control circuit of a water dispenser. The circuit is an improvement to the primary water dispenser circuit. The new temperature regulation and control circuit is additionally provided with an intermediate delay KA and an adjustable controller KSD2. Drinking water can be heated by an electrical heater DSP (digital signal processor)-1 according to the set temperature of the adjustable temperature controller KSD2. The intermediate delay KA can automatically control the electrical heater DSP-1 and the electric thermophore-2 to heat and warm the drinking water. In the temperature regulation and control circuit, the electrical heater can be conveniently regulated by the adjustable temperature controller to heat the drinking water in the range from 30 to 80 degrees centigrade. Thus the heating temperature of the drinking water can be regulated and set according to seasonal change and individual temperature requirements. The temperature regulation and control circuit can satisfy the different-temperature requirements of the drinking water in people's lives.

Description

technical field [0001] The invention relates to a temperature regulating circuit, in particular to a temperature regulating circuit of a water dispenser. Background technique [0002] At present, there is a hot water liner inside an ordinary water dispenser, which is equipped with 2 electric heaters, one for rapid heating and the other for heat preservation, and there is an insulation layer outside the hot water liner. The 2 electric heaters are controlled by 2 temperature control switches, one for heating and one for heat preservation. The temperatures controlled by the two temperature control switches are all fixed values ​​and cannot be adjusted. When the heating temperature control switch detects that the water temperature has not reached the set temperature, it will automatically turn on the power, at this time the red light is on and the electric heater used for rapid heating will quickly heat the drinking water. The switch will be automatically disconnected and the e...
