Abstract

The vacuum heat-preserving refill drinking machine that the utility model discloses a kind of energy automatic shutdown, adopts single-chip microcomputer (4) control technology.Vacuum heat-preserving courage (1) has good heat-insulating property, water after refrigeration or heating, just heating or turn cold lentamente for a long time in vacuum heat-preserving courage (1), effectively reduce the working time of compressor or heater, on this basis, single-chip microcomputer (4) is in controlling refrigeration or heating, by the analog quantity of water temperature sensor (3) output is carried out to continual sampling, can judge whether that someone drinks water, in the time that the continuous time that nobody drinks water, accumulation reached preset value, an I/O terminal of single-chip microcomputer (4) sends off signal (6), control water dispenser and enter off-mode, power savings is remarkable.

Description

A kind of vacuum heat-preserving refill drinking machine of energy automatic shutdown

Affiliated technical field

The utility model relates to a kind of vacuum heat-preserving refill drinking machine of energy automatic shutdown.

Background technology

Traditional have a refill drinking machine, the general heating liner that adopts stainless steel to make individual layer, rapid heat dissipation, in the time that nobody drinks water, heated water can turn cold faster, dependence is arranged on Kick type temperature detect switch (TDS) on heating liner shell and comes the connection of control heater, heat can stop heating, cool can heating again.Also there is similar phenomenon in compressor-type Cold Drinking Water machine, cooled water heating faster causes temperature controller to be connected, the work of drive compression machine, and after disconnecting soon, because the heating of water is very fast, compressor start frequency is also higher for temperature controller.So again and again, consumption electric energy is surprising.

Summary of the invention

In order to overcome the large disadvantage of traditional cold hot shot water machine power consumption, the utility model provides a kind of vacuum heat-preserving courage (1) cold and hot water drinking machine of energy automatic shutdown.

The technical scheme that the utility model technical solution problem adopts is: adopt cold courage or the hot courage of vacuum heat-preserving courage (1) as water dispenser, energy body (2) in cold courage is evaporimeter, energy body (2) in hot courage is heater, in order to measure the temperature of water in cold courage or hot courage, water temperature sensor (3) is placed in to a tubule, then insert the ad-hoc location in cold courage or hot courage, adopt single-chip microcomputer (4) control technology, in controlling refrigeration or heating, analog quantity to water temperature sensor (3) output is carried out continual sampling, in the time that water temperature reaches preset value without the continuous time accumulation of jumping phenomenon, an I/O terminal of single-chip microcomputer (4) sends off signal (6), control water dispenser and enter off-mode.

The beneficial effects of the utility model are, vacuum heat-preserving courage (1) has good heat-insulating property, water after refrigeration or heating, just heating or turn cold lentamente for a long time in heat-insulating internal container, reduce the effective time of compressor or heater work, on this basis, the automatic shut-off function in the time that nobody drinks water, has further reduced the invalid loss of electric energy.

Brief description of the drawings

Fig. 1 is functional-block diagram of the present utility model, 1. vacuum heat-preserving courages in figure, 2. energy body, 3. water temperature sensor, 4. single-chip microcomputer, 5. key circuit, 6. off signal, 7. display circuit.

Detailed description of the invention

Below in conjunction with drawings and Examples, the utility model is described.

In the present embodiment, what introduce is the example of a compressor cooling, refrigeration courage is the vacuum heat-preserving courage (1) that adopts food stage stainless steel to make, heat insulation layer between inner bag and outer courage is evacuated, can delay the heating of courage inner cold water temperature, single-chip microcomputer (4) has adopted the PIC single-chip microcomputer of U.S. MICROCHIP (micro-core) company, water temperature sensor (3) adopts negative tempperature coefficient thermistor, water temperature sensor (3) is placed in from vacuum heat-preserving courage (1) mouthful and extends a pipe of the interior ad-hoc location of vacuum heat-preserving courage (1), the analog quantity of the inner linear change of water temperature sensor (3) is input to an A/D terminal of single-chip microcomputer (4) by lead-in wire, the close ad-hoc location in rear insertion vacuum heat-preserving courage (1) of evaporimeter of compressor refrigeration system is as energy body (2), key circuit (5), display circuit (7) is connected with the I/O terminal of single-chip microcomputer (4).When starting after water dispenser by key circuit (5), single-chip microcomputer (4) is controlled compressor starts refrigeration, and the inner analog quantity of water temperature sensor (3) is sampled always, in the time that the temperature of water drops to set temperature value, compressor stops heating, water in vacuum heat-preserving courage (1) starts cold insulation, if someone drinks water, when cold water is emitted, the normal-temperature water that can supplement equivalent enters vacuum heat-preserving courage (1), make the temperature of the interior water of vacuum heat-preserving courage (1) have suddenly a rising by a relatively large margin, single-chip microcomputer (4) can be synchronizeed it to preserve with real-time time signal as the signal that has people to drink water, when in a predetermined relatively long-time section, water temperature never has unexpected variation, single-chip microcomputer (4) can drink water it signal as nobody is synchronizeed and is preserved with real-time time signal, and send off signal (6) by I/O terminal, make water dispenser enter low power consumption standby state, display circuit (7) is made relevant demonstration.

Claims

1. the vacuum heat-preserving refill drinking machine of an energy automatic shutdown, adopt single-chip microcomputer control technology, it is characterized in that: water dispenser energy body (2) is placed in vacuum heat-preserving courage (1), accept the control signal of single-chip microcomputer (4), water temperature sensor (3) is placed in from vacuum heat-preserving courage (1) mouthful and extends a pipe of the interior ad-hoc location of vacuum heat-preserving courage (1), the analog quantity of the inner linear change of water temperature sensor (3) is input to an A/D terminal of single-chip microcomputer (4) by lead-in wire, display circuit (7) is connected with the I/O terminal of single-chip microcomputer (4), key circuit (5) is connected with the I/O terminal of single-chip microcomputer (4), when water temperature reaches preset value without the continuous time accumulation of jumping phenomenon, an I/O terminal of single-chip microcomputer (4) sends off signal (6), display circuit (7) is made relevant demonstration.
