Description of drawings
Fig. 1 is the control circuit figure of embodiment of the invention drinking device;
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subjected to the restriction of the specific embodiment.
This drinking device comprises a housing, and the top of housing is provided with for the bucket that bucket and water storage are installed, and enclosure interior is equipped with water pump P UMP, calandria and the discharging device that order links on the water route.Former water temperature sensor CN102 for detection of former coolant-temperature gage is installed in the described bucket, the calandria temperature sensor CN101 for detection of the calandria surface temperature is installed on the calandria surface.Under the effect of water pump, the current in the bucket enter the calandria heating through bucket, flow out from discharging device after being heated to the temperature of setting.
One automaton also is installed in this housing, single-chip microcomputer IC101 is installed in this automaton, this single-chip microcomputer IC101 links to each other with calandria temperature sensor CN101 circuit with water pump P UMP, former water temperature sensor CN102 respectively.Described single-chip microcomputer IC101 is after receiving former water temperature sensor CN102 and the detected temperature signal of calandria temperature sensor CN101, in the time range of setting, the voltage that leads to water pump P UMP is cut ripple, thus switching and the discharge of control water pump P UMP.
The electronic device that described hot water temperature's sensor CN101 and former water temperature sensor CN102 are negative temperature coefficient.Along with the variation of the temperature of test point, sensor response out be the variation of resistance value.The meaning of negative temperature coefficient is when temperature is higher, and the resistance value of sensor is less.When temperature was lower, the resistance value of sensor was larger.As shown in Figure 1, the calandria temperature sensor links to each other with capacitor C 101 with resistance R 105.The calandria temperature sensor just is equivalent to a resistance that varies with temperature and change.After the connection, the calandria temperature sensor is connected with R105 and is formed bleeder circuit.Middle dividing point is connected with an input port of single-chip microcomputer.Along with the variation of temperature, the voltage of dividing point changes immediately.This magnitude of voltage will be gathered by the input port of single-chip microcomputer, the temperature value of hence one can see that current institute test point.Capacitor C 101 wherein plays a part to filter interfering signal.
