Abstract
The utility model relates to an automatic temperature control water fountain, which provides various holding temperatures and achieves the manual change in the holding temperature by the application of an automatic temperature control circuit so as to meet different demands of people. The automatic temperature control water fountain consists of a water control tank (5), a cooling water switch (3), a hot water switch (6), a hot liner (4) and a heating pipe (7). The heating process is achieved through the automatic temperature control circuit. The trimming resistor RP is adjusted so as to set the final holding temperature. If water temperature is not the setting temperature after supplying power, a relay K arranged in the automatic temperature control circuit is actuated and the water fountain begins to heat the cooling water; if the water temperature is the setting temperature after supplying power, the relay K arranged in the automatic temperature control circuit is closed, the water fountain stops the heating and keeps in the state of heat preservation.
Description
Technical field
The utility model relates to the automatic temperature-control water dispenser, and its holding temperature can be regulated automatically, has made things convenient for people's use.
Background technology
The present water dispenser that uses, its holding temperature is single, and the coolant-temperature gage that is under the keeping warm mode is higher, is not easy to directly drink.
The utility model content
The objective of the invention is to overcome the weak point in the prior art, provide a kind of holding temperature adjustable water dispenser.
This utility model is made up of control tank, cold water switch, hot-water switch, hot courage and heating tube.Buoyancy aid and valve are fixedly linked in the control tank, valve closing when the lucky submergence of buoyancy aid, buoyancy aid not during submergence valve slightly descend, inner bucket water flows into controls tank.Because the minimum volume of buoyancy aid satisfies the buoyancy that is subjected to when buoyancy aid just is immersed in the water upwards and is subjected to the downward pressure of water with valve and equates, so total energy keeps certain water level in the control tank.
Whether the realization of heating process is controlled by automatic temperature control circuit.Temperature-sensing element RT, resistance R 1, trimmer resistor RP and resistance R 2 are formed bridge for measuring temperature in the automatic temperature control circuit, the base stage of difference amplifier tube VT1 and VT2 is connected on two brachium pontis respectively, as electric signal input end, the VT3 emitter stage connects the VT1 colelctor electrode, the VT3 base stage connects the VT2 colelctor electrode, and the VT3 colelctor electrode is connected on the VT4 base stage as electrical signal through VD1, and the signal of telecommunication amplifies the work of rear drive relay K through VT4, utilize the contactor control circuit of relay K, can realize temperature control.
Operation principle: regulate trimmer resistor RP, to set final heating-up temperature.The energising back does not reach design temperature as if water temperature, the relay K adhesive in the automatic temperature control circuit, and water dispenser begins cold water is heated; If water temperature has reached design temperature, the relay K in the automatic temperature control circuit disconnects, and heating stops, and water dispenser is in keeping warm mode.
Beneficial effect
The utility model has its remarkable advantage:
This utility model provides a kind of new heat preserving mode, and it makes the holding temperature of water dispenser no longer single, and the application by automatic temperature control circuit has realized artificial change holding temperature, to satisfy people's different needs.
Description of drawings
Concrete structure of the present utility model is provided by the following drawings:
Each drawing reference numeral name is called:
1-valve, 2-buoyancy aid, 3-cold water switch, the hot courage of 4-, 5-control tank, 6-hot-water switch, 7-heating tube.
The specific embodiment
Set holding temperature by the resistance that changes trimmer resistor RP before the heating, if water temperature does not reach design temperature, then the resistance of temperature-sensing element RT is greater than the resistance of RP in the automatic temperature control circuit, and relay K is in attracting state, and water dispenser continues heating; If water temperature has reached design temperature, then the resistance of temperature-sensing element RT equals the resistance of RP, and relay K disconnects, and water dispenser changes keeping warm mode automatically over to.
Claims (1)
- The automatic temperature-control water dispenser, comprise control tank (5), cold water switch (3), hot-water switch (6), hot courage (4) and heating tube (7), it is characterized in that: temperature-sensing element RT in the automatic temperature control circuit, resistance R 1, trimmer resistor RP and resistance R 2 are formed bridge for measuring temperature, the base stage of difference amplifier tube VT1 and VT2 is connected on two brachium pontis respectively, as electric signal input end, the VT3 emitter stage connects the VT1 colelctor electrode, the VT3 base stage connects the VT2 colelctor electrode, the VT3 colelctor electrode is connected on the VT4 base stage as electrical signal through VD1, the signal of telecommunication amplifies the work of rear drive relay K through VT4, utilize the contactor control circuit of relay K, can realize temperature control.
