Description
Technical field
The utility model relates to a kind of temperature control circuit, particularly a kind of temperature control circuit of water dispenser.
Background technology
At present, there is a hot water inner bag common drinking machine inside, and 2 electric heaters are equipped with in the inside, one for Fast Heating, another for insulation, have heat-insulation layer outside hot water inner bag.2 electric heaters are controlled by 2 temperature detect switch (TDS)s, one for heating, one for insulation, the temperature that 2 temperature detect switch (TDS)s control is all fixed value, can not adjust.When heating temperature control switch detects that water temperature does not arrive design temperature, can automatically switch on power, now when red and for the electric heater of Fast Heating to potable water Fast Heating, after being heated to design temperature, temperature detect switch (TDS) automatically can disconnect and making and electric heater stopping heating, and now red light goes out.Open the electric heater for being incubated for the temperature detect switch (TDS) be incubated after stopping heating and namely holding stage entered to the micro-heating of potable water, now green light.After temperature drops to certain value, heating temperature control switch resets again to potable water Fast Heating.Circulating-heating like this is until cut off water dispenser general supply.Amber light is power light.
The heating-up temperature of above-mentioned water dispenser setting is a fixed value, and the requirement to potable water temperature according to seasonal variations and individual can not be followed to adjust and set.

The leading-out terminal of thermal protector KSD1 is also connected with the end of incoming cables of the normally open contact KA2 of auxiliary reclay KA.The end of incoming cables of normally open contact KA2 was both connected with zero-power line N through commutation diode D3, dropping resistor R3, green indicating lamp G-LED successively.The leading-out terminal of the normally open contact KA2 of auxiliary reclay KA is connected with zero line N through the electric thermophore DSP-2 be arranged in hot water inner bag again.When electric heater DSP-1 stops heating to the pure water in hot water inner bag because normally closed interlock KA1 disconnects dead electricity, normally open contact KA2 can automatically reset and make electric thermophore DSP-2 obtain electric work.Now green indicating lamp G-LED also obtains electroluminescence.Because of electric thermophore DSP-2, to add heat minimum, so electric thermophore DSP-2 can not improve the temperature of potable water but greatly can reduce the cooling velocity of potable water temperature.Normally closed interlock KA1 again while electric work normally open contact KA2 automatically can disconnect and make electric thermophore DSP-2 dead electricity and quit work, green light also stops luminescence simultaneously.
Thermal protector KSD1 is also connected with adjustable temperature controller KSD2 one end, and the other end of adjustable temperature controller KSD2 is connected with the coil of auxiliary reclay KA, and the leading-out terminal of the coil of auxiliary reclay KA is connected with zero-power line N.The knob of rotary adjustable temperature controller KSD2 can set the heating-up temperature of electric heater DSP-1 to the pure water in hot water inner bag.The design temperature scope of adjustable temperature controller KSD2 is 35-85 DEG C.
Electric heater DSP-1 is also all connected with power ground E with electric thermophore DSP-2.
Adjustable temperature controller KSD2 selects knob temperature controller.
JTX-3C relay selected by auxiliary reclay.
During installation, temperature control circuit plate is contained in water dispenser.Electric heater DSP-1 and electric thermophore DSP-2 is contained in hot water inner bag.The knob of knob adjustable temp. controller KSD2 and three pilot lamp are all contained on drinking machine panel.
The utility model has the advantages that the temperature control circuit providing a kind of water dispenser, this temperature control circuit can adjust the heating-up temperature of electric heater to potable water easily by adjustable temperature controller, and water temperature setting range is 30-85 DEG C.Such can following adjusts according to seasonal variations and individual the heating-up temperature of the requirement of temperature to potable water and sets.Requirements different to potable water temperature in people's life can be met.
