Description
Technical field
The utility model relates to a kind of family expenses heater, particularly a kind of energy-saving drinking machine.
Background technology
In the conventional domestic water dispenser, the heating of water all is to accomplish through built-in hot courage, and the personage a source says that according to industry, 99.3% traditional hot refill drinking machine " poisonous ".The source of its " poison " is " thousand boiling water ", " incrustation scale ", " manufacturing nitrite " etc.Hot refill drinking machine boils for a long time and is prone to produce " thousand boiling water ", though this water seems totally, is the concentrate of harmful substances such as heavy metal, arsenide, and drink can disturb people's gastrointestinal function for a long time, diarrhoea, abdominal distension occur.In addition; Water dispenser is called as household electrical appliance " power consumption king ": to make 1 liter of hot water is example; Under the state that does not shut down; Power is that 0.5 kilowatt conventional domestic water dispenser is daily wanted power consumption 1.8 degree, exactly because its operation principle of " burning and stopping " has caused the energy waste more than 90% virtually.
Summary of the invention
Use this novel disclosed a kind of energy-saving drinking machine, comprise heater and water storage device, said water dispenser also comprises control device, and heater is connected control device through circuit respectively with water storage device.
In the said water storage device condensate tank of dehumidifier is set, said Level monitor comprises level sensor, and level sensor connects said control device through circuit.
Said condensate tank of dehumidifier is provided with the lower limit valve, and the lower limit valve connects said control device through circuit.
Said condensate tank of dehumidifier is provided with upper limit valve, and upper limit valve connects said control device through circuit.
In the said water storage device temperature detector is set, said temperature detector comprises cooling-water temperature sensor, and cooling-water temperature sensor connects said control device through circuit.
In the said energy-saving drinking machine room temperature detector is set, said room temperature detector comprises temperature sensor, and temperature sensor connects said control device through circuit.
Said energy-saving drinking machine comprises display floater, shows water level monitoring, current water temperature and current room temperature, and said display floater connects said control device through circuit.
Said control device comprises resistance R 1, capacitor C 1, inductance L 1, diode, triode, power supply, and said resistance R 1 and capacitor C 1 parallel connection back is with after inductance L 1 is connected, and is parallelly connected with diode again, connects with triode and power supply again.
When firm unlatching water dispenser or use middle water level drop to minimum; Water dispenser is mended full water automatically, and heating with full power to boiling stops heating then, can detect the boiled mistake of water through the temperature sensor single-chip microcomputer; And this state remembered, show the boiled mistake of water through the display floater plate simultaneously.Stop to reduce to 96 water dispensers when spending when water temperature after the heating and get into insulation, this moment, water dispenser can be selected different power to feed water with water level according to room temperature at that time to be incubated, to make water temperature between 88 ° of C-96 ° of C, reach balance; Because can not especially accurately find in the reality makes water temperature remain on 88 ° of power between C-96 ° of C; So the water temperature of water dispenser perhaps can be with the very slowly rising or the reduction of speed; When this moment, if water temperature was lower than 88 ° of C; It is slightly little to explain that the insulation power ratio needs, and water dispenser can automatic total power quickly heat up to 96 ° of C entering insulation more then; When if water temperature is higher than 96 ° of C, it is big slightly to explain that actual insulation power ratio needs, and water dispenser can stop insulation automatically and when water temperature is reduced to 88 ℃, be incubated again, adopts the minimum power insulation again behind heating with full power to 96 degree then, repeats time process.Not only avoided the repeatedly boiling of water by this method, and reduced the water heater burning and stopped infringement and waste of electric energy switch.
By the room temperature situation of different latitude Various Seasonal, can room temperature range be confirmed between 10-35 ℃ that the heat of room temperature water dissipates to be influenced and can be obtained by experience.Can be got by table 1, water is little 0-100 ℃ of scope internal ratio thermal change, can be approximately constant.
The specific heat capacity of table 1 water under different temperatures
| Temperature (℃) | 5 | 10 | 15 | 20 | 25 | 30 | 35 | 40 | 45 | 50 |
| Specific heat (J/kg ℃) | 4204 | 4194 | 4187 | 4183 | 4179 | 4179 | 4179 | 4179 | 4179 | 4179 |
| Temperature (℃) | 55 | 60 | 65 | 70 | 75 | 80 | 85 | 90 | 95 | 100 |
| Specific heat (J/kg ℃) | 4179 | 4183 | 4183 | 4187 | 4191 | 4195 | 4204 | 4208 | 4216 | 4220 |
Being incubated required power output is to obtain through experiment in the reality and correlation computations.When supposing that room temperature is a ℃, the time when using stopwatch to measure quality in the water tank to drop to (n-0.5) ℃ as the water of m by n ℃ is t, and liberated heat is:
C is that specific heat of water holds in the formula; M is the quality of water; Here the quality of water can go out through the calculated signals that water temperature detects;
is temperature variation, is 0.5 ℃ here.
For guaranteeing that water temperature is constant, must make the heat that water absorbs in the water heater equal liberated heat, establishing the heating tube heat generation rate is η, then absorbs heat and does
U is a supply voltage in the formula, and R is the electrothermal tube resistance, and t can be got by formula (1).Can know
=
; If the heat dissipation process of water at the uniform velocity, can remain on a ℃ of required voltage with water
Healthy for guaranteeing drinking-water, the design avoids drinking mixed cold and hot water, promptly respectively establishes a position sensor on water tank top and bottom, and through the Single-chip Controlling magnetic valve, not water outlet when water is not opened is not intake when water flows to end.
Health energy-saving drinking water machine among the design can be selected the different power insulation automatically according to different room temperatures; Being intended to reach dissipation energy and water dispenser heating generation heat balances each other; Avoid repeated heating through keeping water temperature; Not only can not produce by " thousand boiling water ", also significantly reduce the number of times that water dispenser " burns and stops ", practice thrift electric energy.
Description of drawings
Fig. 1 system major loop schematic diagram
System hardware adopts buck circuit control electrothermal tube voltage, and triode full-control type device is selected IGBT for use among the figure, and D1 is a fly-wheel diode.When V was in on-state, power supply powered to the load, Uo=Ui; When V was in off-state, load current was through diode D afterflow, and voltage U o is approximately zero, to one-period T end, drove the V conducting again, repeated the process of one-period.The mean value of load voltage is:
Ton is the time that V is in on-state in the formula, and toff is the time that V is in off-state, and T is a switch periods, and α is the conducting dutycycle, and abbreviation dutycycle or conduction ratio (α=ton/T).Hence one can see that, and the average voltage Uo that outputs to load is supply voltage to the maximum, if reduce duty cycle alpha, then Uo reduces thereupon, because output voltage is lower than input voltage, so claim that this circuit is a buck circuit.
