Heating mechanism of instantaneously heated type drinking machine
Technical field
The invention belongs to the water dispenser technical field, be specially heating mechanism of instantaneously heated type drinking machine.
Background technology
The operation principle that the tradition water dispenser boils water is: cold water enters from hot courage bottom, and hot water flows out from hot courage top, utilizes hot water proportion to be lower than the characteristics of cold water proportion, and when opening the hot water tap, cold water enters hot courage hot water is extruded from the top from the bottom; In hot courage, heater is set, uses the temperature detect switch (TDS) control heater, when the water in the hot courage burns to 95 ℃ of left and right sides, outage automatically, heater quits work, when the water temperature in the heating water tank is reduced to 78 ℃ of left and right sides, energising automatically, heater is reworked.Under the water dispenser holding state, hot courage always is in the circulation that repeats to heat, and power wastage is surprising; And the water in the hot courage also can be aging gradually because repeating heating, loses activity, and influences health.Detect according to specialty, a power is the common water dispenser of 550W, and under holding state, per hour power consumption is 0.0354 degree, power consumption every day 0.85 degree, and annual power consumption 310 degree, national hundreds of millions water dispenser will slattern hundreds of hundred million degree every year.
Also there is secondary pollution problem in the problem that the tradition water dispenser repeats to heat except existence.Because in use normal owing to unclean air, dust enter water tank and the bucket that does not seal, and polluted water; Bucket repeatedly recycles, and also is easy to generate pollution, endangers healthy; And bottled water is because of its volume is big, uses and transports also very inconvenient.
Summary of the invention

The specific embodiment
The invention will be further described below in conjunction with Figure of description.
As shown in the figure, the diversion column 2 one tunnel of water dispenser is connected with cold water faucet 3, another road is connected with water inlet pipe 5, water inlet pipe 5 is connected with the water inlet of micro pump 6, the delivery port of micro pump 6 is connected with heater 7 bottom water inlets by pipeline, heater 7 top delivery ports are connected with hot water tap 12, described heater 7 is connected and composed by one group of heating pipe 8 who is connected in series connection mutually, the heater 9 of connection parallel with one another is set respectively in the heating pipe 8, adjacent heating pipe's 8 top delivery port is connected heater 9 with bottom water inlet pipeline, micro pump 6 is connected with power supply 15 circuit.Heating pipe 8 and respective heater 9 are more than three or three, and the delivery port of micro pump 6 is connected with first heating pipe's 8 bottom water inlets by pipeline, and last heating pipe's 8 top delivery port is connected with hot water tap 12.Micro pump 6 front ends are connected in series successively variable resistor 13, transformer 14, bridge rectifier 16 are set.Be equipped with temperature controller 10 and anti-dry heating temperature controller 11 on last heating pipe's 8 the outer tube wall, temperature controller 10 is connected with power supply 15, micro pump 6 circuit, and anti-dry heating temperature controller 11 is connected with power supply 15, heater 9 circuit.
When above-mentioned heating mechanism of instantaneously heated type drinking machine is used for bagged water dispenser, the upper end of described diversion column 2 is provided with water conservancy diversion tip 2a, the pod apertures 2b that one or more are communicated with diversion column 2 inner chambers is set on the water conservancy diversion tip 2a, water conservancy diversion tip 2a base diameter is greater than diversion column 2 diameters, and the top of water conservancy diversion tip 2a 1/2nd height evenly is provided with three pod apertures 2b.Water conservancy diversion tip 2a thrusts in the water bag 1, and diversion column 2 lower ends are connected with three-way pipe 4 one ends, and three-way pipe 4 other two ends are connected with cold water faucet 3, hot water inlet pipe 5 respectively.During use, water bag 1 own wt impels water conservancy diversion tip 2a to puncture the film of water bag 1, simultaneously under the elastic shrinkage and water deadweight extruding of film, film and water conservancy diversion tip 2a conical surface stabilized seal, form the water intake mechanism of sealing, its good sealing effect, antileaking, avoided the pollution of air, dust, stopped the generation of secondary pollution water body.Above-mentioned heating mechanism of instantaneously heated type drinking machine also can directly replace the heating arrangements of traditional water dispenser, has reduced production cost.
Heating pipe 8 outer wall is close to and is set together, and improves heat energy utilization rate and firing rate.When temperature controller 10 reaches design temperature, micro pump 6 unlatching work, temperature controller 10 can automatically reset.When anti-dry heating temperature controller 11 reaches design temperature, automatically outage, the heater 9 that is connected with its circuit cuts off the power supply, and ensures safe in utilizationly, and anti-dry heating temperature controller 11 needs hand-reset.The power of heater 9 is controlled in the 3000W, further ensures safe in utilization.The resistance of variable resistor 13 is set according to actual needs, can be by regulating the resistance of variable resistor 13, the water velocity of control micro pump 6, water velocity generally is controlled at 20-30ml/ second, and then regulates the hot water temperature, and water velocity is slow, leaving water temperature is just high, otherwise just low.When water velocity is 20ml/ during second, what the hot water tap was flowed out is exactly boiling water.Transformer 14 is reduced to required low tension with the 220V civil power, generally is reduced to 6-12v low pressure.The effect of bridge rectifier 16 is that alternating current is become direct current, and concrete structure is existing known technology.Must wait a moment 5-30 time second when connecing first glass of water, environment temperature the when length of waiting time is used by water dispenser and the decision of the height of cold water temperature at every turn.Environment temperature and cold water temperature are high more, and the time of waiting is just short more.After first glass of boiling water flows out,, then need not wait plug and play if get second glass or any cup.Hot water tap 12 can charged magnet valve, also can not establish valve.The hot water tap 12 of charged magnet valve is connected with power supply 15 circuit, prevents that air, dust from entering heating pipe's 8 internal contamination water bodys from hot water tap 12.
The magnetic valve that turns on the power switch energising back hot water tap 12 is opened simultaneously, heater 9 is started working, when heating reaches the design temperature of temperature controller 10, micro pump 6 unlatching work, drinking water enters in the heater 7 from pump outlet, after the heater 9 continuous heating through connection parallel with one another, boiling water promptly flows out from hot water tap 12, and firing rate is fast; Outage back hot water tap's 12 closed electromagnetic valve, micro pump 6 quits work, and does not have water to flow out among the hot water tap 12, accomplished that electric water flowing is just logical, electricity is cut off the water supply and is just stopped, and prevents that the phenomenon that repeats to heat from taking place, avoid boiling water aging, compare power saving more than 80% with traditional water dispenser.
