The present invention realizes that method that water dispenser goes out boiled water immediately according to three kinds of different duties of water dispenser, works respectively as follows:
One, as shown in Figure 2, when water dispenser is connected power supply, water dispenser promptly is in the duty of the heating and the insulation of water tank water, control circuit will be worked according to the following steps: (one), after the user opens the water dispenser power supply, and control circuit detects the temperature of water in the water tanks 5 by the temperature sensors in the water dispenser water tank 5 502; When (two), the temperature of water is lower than setting value in temperature sensor 502 detects water tank 5, control circuit control water pump 4 and heater 1 work, to heat in the input heater 1 behind the current stabilization in the water suction constant-current stabilizer 3 in the water tank 5, and the water that heater 1 heated will be failed in the recovery tank 5 by pipeline; (3), when the temperature that detects water in the water tank 5 when temperature sensor 502 reaches setting value, control circuit control water pump 4 and heater 1 quit work.
The concrete course of work is as follows: when temperature sensor 502 detects coolant-temperature gage in the water tank 5 and is lower than setting value, control circuit control water pump 4 and heater 1 work, water in the water tank 5 is extracted out by water pump 4, the pipeline 602 of flowing through enters water pump 4 water inlets 402, be drawn in the water pump 4, flow out from water pump 4 delivery ports 401 again, current 601 enter constant-current stabilizer 3 water inlets 303 by the road, current are after current stabilization valve body 304 flows into current stabilization chamber 305, current are divided into two-way, the condensation cover 105 that the water inlet 108 that one route delivery port 301 flows into heaters 1 is flowed through in the heater 1 enters in the heater 1, another road flow stabilizing valve 304 of flowing through enters spill cavity 306, flow out through another delivery port 302 and enter the three-way device 7 water tank water inlet 503 of flowing through and enter in the water tank 5, if water flow pressure is big, the water that then flows into spill cavity 306 is just many; If water flow pressure is little, the water that then flows into spill cavity 306 is just few.Like this, the flow of water just is well controlled, reach more stable level, water through the constant-current stabilizer current stabilization flows into the water of heater 1 by 101 heating of helical form heater, because water pump 4 is constantly with water suction heater 1 from water tank 5, when the water temperature of heater 1 raises, its water surface also can constantly raise, but go out Water gate valve 2 and be in closed condition this moment, water does not flow out from go out Water gate valve 2, last water flows out from the steam outlet 107 at heater 1 top, and water 604 flows into three-way device 7 by the road, flows into water tank water inlet 503 by three-way device 7 again and flows in the water tank 5.If the water temperature that temperature sensor 502 records still is lower than temperature value is set, control circuit will continue control water pump 4 and heater 1 work, like this, water in the water tank 5 is still by in the suction heater 1 constantly, in the also constantly defeated recovery tank 5 of the water of heating, so continuous circulation constantly raises the temperature of the water in the water tank 5.When the coolant-temperature gage in the water tank 5 is elevated to design temperature, found out by temperature sensor 502, control circuit is according to temperature sensor 502 data of surveying, control water pump 4 quits work with heater 1, the heating and the heat insulation work of the water in the water tank 5 have so just been finished, have only temperature when water in the water tank 5 to be reduced to setting value once more when following, control circuit just can start water pump 4 once more and reenter with heater 1 and heat and the heat insulation work state.
Two, as shown in Figure 3, when the user selects the water fountain effluent function, water dispenser is in the duty of emitting boiled water, control circuit will be worked according to the following steps: (one), after the user selects the water fountain effluent function, and control circuit detects the temperature of water in the heaters 1 by the temperature sensor in the heater 1 104; (2), when the temperature that detects water in the heater 1 when temperature sensor 104 is lower than setting value, the 1 beginning heating work of control circuit control heater; When (three), the temperature that detects water in the heater 1 when temperature sensor 104 reaches setting value, control circuit is controlled water pump 4 and is gone out Water gate valve 2 and starts working, behind water suction constant-current stabilizer 3 current stabilizations in the water tank 5, input heater 1 heats, and flows out by the Water gate valve of opening 2 that goes out; (4), when the user cancels the water fountain effluent function, control circuit control heater 1, water pump 4 and go out Water gate valve 2 and quit work.
The concrete course of work is as follows: after the user selects the water fountain effluent function, when the temperature that detects water in the heater 1 when temperature sensor 104 is lower than setting value, 1 work of control circuit control heater, the water that retains in the heater 1 is heated to boiling, when the temperature that detects water in the heater 1 when temperature sensor 104 reaches setting value, control circuit is controlled water pump 4 and is gone out Water gate valve 2 and starts working, like this, going out Water gate valve 2 is opened, water flows out the water inlet 202 that enters out Water gate valve 2 from the outlet pipe 103 in the heater 1, flow into out Water gate valve 2, flow out from the delivery port 201 that goes out Water gate valve 2 again.Simultaneously, water in the water tank 5 is extracted out by water pump 4, the pipeline 602 of flowing through enters water pump 4 water inlets 402, be drawn in the water pump 4, flow out from water pump 4 delivery ports 401 again, current by the road 601 enter constant-current stabilizer 3 water inlets 303 and flow into current stabilization chambeies 305 after, current are divided into two-way, the condensation cover 105 that the water inlet 108 that one route delivery port 301 flows into heaters 1 is flowed through in the heater 1 enters in the heater 1, the water inlet 303 that another road flows into constant-current stabilizer 3 enters current stabilization chamber 305, the valve body 304 of flowing through then, enter spill cavity 306 by the through hole 308 between current stabilization chamber 305 and the spill cavity 306, another delivery port on spill cavity 306 302 flows out and enters the three-way device 7 water tank water inlet 503 of flowing through and enter in the water tank 5 again.If water flow pressure is big, the water that then flows into spill cavity 306 is just many.If water flow pressure is little, the water that then flows into spill cavity 306 is just few.Like this, the flow of water just is well controlled, reach more stable level, the water of process constant-current stabilizer current stabilization flows into the water of heater 1 by 101 heating of helical form heater through the water of constant-current stabilizer current stabilization, flow out the water inlet 202 that enters out Water gate valve 2 from heater 1 interior outlet pipe 103 again, flow into out Water gate valve 2, flow out from the delivery port 201 that goes out Water gate valve 2 again.Owing to flow into the water yield of heater 1 is to handle through constant-current stabilizer 3 current stabilizations, stability of flow, so when the user selects water outlet, the water yield that goes out Water gate valve 2 outflows is the same with the water yield that flows into heater 1, for this reason, water quilt in the water tank 5 is suction heater 1 constantly, reach the water yield basically identical of turnover in the heater 1, under the constant situation of the heating power of the heater 101 of heater 1, also just guaranteed the heated temperature basically identical of water in the heater 1, can constantly flow out the boiling water of boiling from heater 1, water can not flow out from the steam outlet 107 at heater 1 top yet like this.Because outlet 107 of the steam of heater 1 and water inlet 108 are arranged on the top of heater 1, outlet conduit 103 is arranged on the below of steam outlet 107 and water inlet 108, and is positioned at heater 101 tops.Owing to producing water vapour in the process that adds hot water, because entering the water yield of heater and outflow heater is consistent substantially, therefore at this moment only there is water vapour to flow out from steam outlet 107, but, owing in heater 1, be provided with condensation cover 105, the through hole at the top of condensation cover 105 is socketed in the steam outlet 106, and be in the top of heater 1, heater 101 is positioned at the bottom of heater 1, because it is lower by the coolant-temperature gage of water inlet 108 that water tank 5 is pumped into heater 1, and water inlet 108 is in the top of condensation cover 105, for this reason, the water of suction heater 1 constantly waters on condensation cover 105 from water tank 5, cooling condensation cover 105, make the temperature of condensation cover 105 remain on lower level always, when the water vapour in the heater 1 rose to condensation cover 105, major part was condensed into water, and the steam that has only minority not to be condensed into water enters in the water tank 5 by pipeline 604, reduced water vapour so effectively, the difficult problem of the steam of emerging easily when having solved the water dispenser boiling.
In this system, when adopting electromagnetic pump, can produce very big noise, in order to solve the too big problem of electromagnetic pump noise, water pump 4 has been selected cheap vane wheel type centrifugal pump for use, it is low that it has a noise, cheap advantage, but when drawing water, the pump-out in the unit interval can be subjected to the influence of the water yield in the water tank 5, i.e. hydraulic pressure difference, the water yield that water pump 4 is taken out is also different, so also influence is entered the stability of the leaving water temperature after heater 1 heats, seethe with excitement in order to guarantee the water that 1 heating is emitted through heater, and be stable, in this system, added constant-current stabilizer 3, when the water that will flow through constant-current stabilizer 3 enters heater 1 after by current stabilization again, make the stability of flow of water, be the purpose of the boiling water of boiling to reach the water of emitting from water dispenser always.
Described constant-current stabilizer 3 is provided with valve body 304, current stabilization chamber 305 and spill cavity 306, be provided with through hole 308 between current stabilization chamber 305 and the spill cavity 306, the set cap of the one end portion 3041 of valve body 304 is in through hole 308 tops in the spill cavity 306, the other end of valve body 304 is in the current stabilization chamber 305, its end is arranged in stop 307 centers of putting that 305 bottoms, current stabilization chamber are provided with, and be slidingly connected with its formation, described current stabilization chamber 305 is provided with delivery port 301 and water inlet 303, and described spill cavity 306 is provided with delivery port 302.
The operation principle of constant-current stabilizer 3 is as follows: when current flow into described constant-current stabilizer 3 through water pump 4, at first flow into current stabilization chamber 305, current are divided into two-way then, the delivery port 301 that is provided with on the current stabilization chamber 305 of leading up to flows into heaters 1, another road valve body 304 of flowing through, enter spill cavity 306 through the through hole 308 between current stabilization chamber 305 and the spill cavity 306, the delivery port 302 through spill cavity 306 flows out in three-way device 7 enters water tank 5 again.If water flow pressure is too little, because the deadweight of valve body 304, the distance that the cap portion 3041 on the valve body 304 is open is less, and the gap that the through hole 308 between current stabilization chamber 305 and the spill cavity 306 is opened is less, and it is just less that current flow into spill cavity 306.If water flow pressure is bigger, then to promote the thrust of valve body 304 just big for water flow pressure, and the distance that the cap portion 3041 of valve body 304 is pushed open is just bigger, is about to current stabilization chamber 305 and opens also greatly with the through hole 308 between the spill cavity 306, and the water yield that flows into spill cavity 306 just greatly.The size that enters the water yield of spill cavity 306 is to decide according to the size that flows into hydraulic pressure in the current stabilization chamber 305, hydraulic pressure is big more, the water yield that then enters spill cavity 306 is just many more, hydraulic pressure is more little, the water yield that then enters spill cavity 306 is just few more, constant-current stabilizer 3 has just played good VOLTAG CHOPPER VEGULATOR effect like this, just can control the water yield that flows into heater 1 preferably, thereby has guaranteed the stability of the water outlet of water dispenser.
Three, as shown in Figure 4, after water dispenser is connected power supply, water dispenser is in the heating of water tank water and heat insulation work state or when the user selects the water fountain effluent function, water dispenser is in the course of work of the duty of emitting boiled water, when water dispenser is anhydrous, water dispenser is in anhydrous anti-dry duty, and control circuit will be worked according to the following steps: (one), control circuit detect the current value of water pump 4; (2), when the survey current value when setting current value, control circuit control heater 1 and water pump 4 quit work, or control circuit will be worked according to the following steps: whether (one), control circuit detect magnetic switch 802 closed; (2), when institute's survey magnetic switch 802 is closed, control circuit control heater 1 and water pump 4 quit work.
The concrete course of work is as follows: after water dispenser is connected power supply, control circuit detects the current value of water pump 4, when the current value of water pump 4 during greater than the current value set, the normal operating conditions work that the control circuit follow procedure requires, be that water dispenser is in the heating and the heat insulation work state of water tank 5 water or when the user selected the water fountain effluent function, water dispenser was in the duty of emitting boiled water.If the current value that control circuit detects water pump 4 is during less than the current value set, control circuit quits work control heater 1 and water pump 4.As: if record in water tank 5 when anhydrous, the operating current of water pump 4 is 100mA, so, it is 100mA that control program in control circuit is set water pump 4 current value when anhydrous, the working current value of the water pump 4 that records when control circuit is during smaller or equal to 100mA, and the control program in the control circuit quits work with regard to control heater 1 and water pump 4.As: the current value of the detected water pump 4 of control circuit is 130mA, illustrates to also have water in the water tank 5, and control circuit works on control heater 1 and water pump 4.If the current value of the detected water pump 4 of control circuit is 100mA or during less than 100mA, then illustrate in the water tank 5 anhydrous, control circuit will control heater 1 and water pump 4 quit work.
Be the control method of the another kind of anhydrous anti-dry of the present invention as shown in Figure 4, as can be seen from the figure, described anti-dry burning device 8 is vertical cavity body structures of upper and lower opening, be provided with magnetic float 801 in the cavity, the outer bottom of cavity is provided with magnetic switch 802, be arranged on the delivery port 502 and the pipeline 602 between the water pump 4 of water tank 5, when water flows through pipeline 602, also flow in the cavity of anti-dry burning device 8, magnetic float 801 will be floated.When in the water tank 5 when anhydrous, magnetic float 801 will drop to the bottom because of deadweight, and the position that magnetic float 801 falls is corresponding with magnetic switch 802, and can make magnetic switch 802 closures.When the water yield in the water tank 5 during greater than anti-dry position A, because buoyancy of water, magnetic float 801 is floated, make magnetic float 801 leave magnetic switch 802, at this moment, magnetic switch 802 just disconnects, when control circuit detects magnetic switch 802 disconnections, illustrate to also have water in the water tank 5, like this, control circuit just can be controlled this system's operate as normal according to the residing duty of system.Whether control circuit comes control heater 1 and water pump 4 to work by the break-make that detects the magnetic switch 802 on the anti-dry burning device 8; thereby reach water dispenser when water tank 5 is anhydrous; the heating of control circuit control heater 1 no power; the safety problem of having avoided heater 1 to be burnt out when anhydrous reaches the protection purpose of anhydrous anti-dry.
The preheat temperature computing formula of the specific embodiment of preheating water of the present invention and acquisition boiling water is as follows:
If seek out the boiling water of 100 degree, get then that heater 101 power are 2500W in the heater 1, the flow of water intaking pump 4 is 10 Grams Per Seconds.The thermal conversion efficiency that heater 1 adds hot water is 98%, then can immediately water temperature be improved: (the 4.2nd, specific heat of water holds the 2500W*0.98/10/4.2=58.3 degree, it is the required heat of the every raising 1 degree temperature of material of unit mass, unit is a joule), then the coolant-temperature gage of preheating is the 100-58.3=41.7 degree.In the time will drinking 100 degree boiling water, the warm water that is preheating to 41.7 degree can obtain the boiling water of 100 degree after the instant heating by heater 1.
If only seek out the hot water of 80 degree, under other conditions did not become situation, the power of the heater in the device 1 101 can be adjusted to mean power was that P=(80-41.7) * 10*4.2/0.98=1727W gets final product.
