Abstract

The utility model relates to an energy saving drinking water machine which adaptively shuts down, and comprises a single chip microcomputer (1), a hot water temperature sensor (2), a single chip clock circuit (3), a key-press circuit (4), a display circuit (5) and a heating pipe driving circuit (6). When the single chip microcomputer (1) controls drinking water in constant temperature, temperature sampling results of the hot water temperature sensor (2) is tracked timely, when people drink, the water temperature of a region which is close to a water inlet of a hot liner changes greatly in a short time, when no people drink, the water temperature is always kept in a critical value, when the single chip microcomputer can not detect that the water temperature is not greatly changed in a short time in a relatively long time, which is regarded as no people use water, and an adaptive shut down mode of the drinking water is automatically transferred to a low consumption holding state. The energy saving drinking water machine has simple circuit structure, low cost and remarkable energy saving effect.

Description

A kind of energy-saving drinking machine of self-adaptation shutdown

Affiliated technical field

The utility model relates to a kind of energy-saving drinking machine that can determine the suitable unused time automatically.

Background technology

At present, can preset the shutdown function though the part water dispenser possesses, owing to need human intervention, seem not too convenient and flexibly, the part water dispenser adopts photoelectricity, special shutdown measure such as infrared, and cost increases.

Summary of the invention

In order to overcome the existing shortcoming of water dispenser on the shutdown function, the utility model provides a kind of energy-saving drinking machine of self-adaptation shutdown, it can be from motion tracking people's drinking-water activity, when unmanned potable water in a relative long period, automatically shutdown enters real low consumption holding state for energy savings.

The technical scheme that its technical matters that solves the utility model adopts is: monolithic clock circuit (3) links to each other with the I/O terminal of single-chip microcomputer (1), constituting serial ports connects, hot water temperature's sensor (2) is installed in the hot courage of water dispenser near on the courage wall of water inlet, hot water temperature's sensor (2) is gone up linear change modeling amount is input to single-chip microcomputer (1) by terminal pin an A/D input end, an I/O terminal of single-chip microcomputer (1) constitutes heating tube driving circuit (6) by light idol drives power scr, some I/O terminal mouths of display circuit (5) and single-chip microcomputer (1) link to each other, and key circuit (4) links to each other with the I/O terminal of single-chip microcomputer (1).When single-chip microcomputer (1) is carrying out potable water thermostatically controlled the time, constantly follow the tracks of the temperature sampling result of hot water temperature's sensor (2), during someone potable water, outflow along with hot water, the hot courage water inlet of water dispenser can replenish the into cold water of equivalent immediately, cause this zone water temperature that bigger in short-term variation can take place, during unmanned potable water, water temperature can be stabilized on the critical value always, when single-chip microcomputer detects water temperature in one long relatively period bigger in short-term variation is not arranged, promptly be considered as unmanned water, water dispenser self-adaptation shutdown mode can change the low consumption holding state automatically over to.

The beneficial effects of the utility model are, are that the telemetry circuit of core is simple in structure, cheap with the single-chip microcomputer, and easy to use flexible, energy-saving effect is remarkable.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a circuit part functional-block diagram of the present utility model, 1. single-chip microcomputers among the figure, 2. hot water temperature's sensor, 3. monolithic clock circuit, 4. key circuit, 5. display circuit, 6. heating tube driving circuit.

Embodiment

In the present embodiment, the chip that single-chip microcomputer (1) adopts is PIC16F873, hot water temperature's sensor (2) adopts negative tempperature coefficient thermistor, 25 ℃ of normal resistances are 10K Ω, 10 A/D input terminal AN0 of branch pressure voltage input single-chip microcomputer (1) PIC16F873 that itself and another 10K Ω resistance is connected, monolithic clock circuit (3) adopts the DS1302 chip, its SCLK, I/O, and the RET terminal respectively and the RC2 of single-chip microcomputer (1) PIC16F873, three I/O terminals of RC3 and RC0 link to each other, constituting serial ports connects, single-chip microcomputer (1) PIC16F873 is carrying out temperature sampling, the self-adaptation shutdown, when time showing and self check, all the time all to carry out real-time Communication for Power with monolithic clock, key circuit (4) is made up of resistor network, adopt single line to be connected to the A/D input terminal AN3 of single-chip microcomputer (1) PIC16F873, key assignments adopts the way of A/D scanning to differentiate, display circuit (5) is made up of LED charactron and LED light, carry out dynamically and show, pin is connected respectively to the I/O terminal RA5 of single-chip microcomputer (1) PIC16F873, RC4, RC5, RC6, RC7, RB0-RB6 can show real time temperature respectively, real-time time, unused time, self-detection result, warning message or the like content.The I/O terminal RC1 of single-chip microcomputer (1) PIC16F873 constitutes heating tube driving circuit (6) by light idol drives power scr.After the potable water people is by the button start, the RC1 of single-chip microcomputer (1) PIC16F873 heats to potable water by light idol drives power scr, when reaching default value or selective value, single-chip microcomputer (1) PIC16F873 begins potable water is carried out thermostatic control, while presets the unused time automatically and follows the tracks of the temperature sampling result of hot water temperature's sensor (2) constantly, during someone potable water, outflow along with hot water, the hot courage water inlet of water dispenser can replenish the into cold water of equivalent immediately, cause this zone water temperature that bigger in short-term variation can take place, single-chip microcomputer (1) PIC16F873 can refresh the unused time immediately automatically, when reentering thermostatic control, single-chip microcomputer (1) PIC16F873 can preset the unused time again again automatically, when unmanned water, water temperature can be stabilized on the critical value always, when single-chip microcomputer detects water temperature in one long relatively period bigger in short-term variation is not arranged, it is promptly locked to preset the unused time, be considered as unmanned water, water dispenser self-adaptation shutdown mode can change the low consumption holding state automatically over to.
