Fig. 2 is the structural representation of embodiment 2.
The specific embodiment
Embodiment 1
Referring to Fig. 1, the electric heating drinking machine that connects pressure water source comprises an electric heating inner bag 1 that is connected with pressure water source.In inner bag water inlet and pressure water source water pipe connecting road inner bag entering water electromagnetic valve 2 is installed, this magnetic valve is exactly the water inlet main valve of whole water dispenser usually.The delivery port of inner bag 1 is connected with four depotition cocks.Wherein also be connected with tube-in-tube heat exchanger 6 between three depotition cocks 3,4,5 and the inner bag 1, reducing the leaving water temperature of these three depotition cocks, and the cold water that enters inner bag 1 carried out preheating.In order to prevent that producing steam in adding the process of hot water causes inner bag 1 hypertonia, inner bag 1 also is connected with a capillary 7, and capillary 7 plays the effect of pressure releasing device.The above is the existing structure of water dispenser.Characteristics of the present utility model are in the water lines between inner bag entering water electromagnetic valve 2 and depotition cock pressure inductor 8 to be installed, and inner bag entering water electromagnetic valve 2 with pressure inductor 8 as the control signal source.Pressure inductor 8 can be installed in from inner bag entering water electromagnetic valve 2 to the water lines any depotition cock, comprises being installed in the inner bag 1.The type of pressure inductor 8 can be mechanical compression switch, electronic pressure sensor or pressure transmitter.The control circuit of 8 pairs of entering water electromagnetic valves 2 of relevant pressure inductor can be selected for use from the pressure control circuit of routine according to control logic of the present utility model.
During water dispenser work, the water process entering water electromagnetic valve 2 injection inner bags 1 from pressure water source supply water to each depotition cock after inner bag 1 heating.Under the situation that all depotition cocks are all closed, water pressure from entering water electromagnetic valve 2 to the water lines any depotition cock is all higher, cause pressure inductor 8 to produce control signal (for example closure of mechanical compression switch), this signal makes entering water electromagnetic valve 2 close by control circuit, thereby avoids inner bag 1 to bear the high pressure of pressure water source.After opening any depotition cock, water pressure from entering water electromagnetic valve 2 to the water lines any depotition cock will reduce, after water pressure is reduced to a certain degree, pressure inductor 8 produces control signal (for example disconnection of mechanical compression switch) once more, this signal makes entering water electromagnetic valve 2 open the water dispenser normal water supply by control circuit.
Embodiment 2
In last embodiment, when inner bag entering water electromagnetic valve 2 was closed, inner bag 1 still maintained certain pressure.This pressure will make the water in the inner bag 1 let out through capillary 7.Though capillary 7 has very big damping action, but because the compressibility hardly of water, the each several part pipeline of water dispenser all is to make with rigid material usually in addition, almost there is not elasticity, so after entering water electromagnetic valve 2 is closed, as long as leak some water from inner bag 1, the water pressure in the inner bag 1 will be reduced to rapidly is enough to make pressure inductor 8 to produce the degree of control signal, causes inner bag entering water electromagnetic valve 2 to be opened.The result forms a kind of like this poor circulation: the water in the inner bag 1 constantly lets out through capillary 7, and pressure water source constantly replenishes water inlet to inner bag 1 again, causes waste.For addressing this problem, present embodiment as shown in Figure 2, in the water lines between inner bag 1 delivery port and depotition cock magnetic valve 9 is installed, pressure inductor 8 is installed in the water lines between magnetic valve 9 and the depotition cock, magnetic valve 9 with inner bag entering water electromagnetic valve 2 jointly with pressure inductor 8 as the control signal source.Under the control of pressure inductor 8, magnetic valve 9 opens, cuts out together with inner bag entering water electromagnetic valve 2.When magnetic valve 9 cuts out with inner bag entering water electromagnetic valve 2, even the water pressure in the inner bag 1 reduces rapidly because of the leakage of capillary 7, but as long as depotition cock is not opened, the water pressure at place, pressure inductor 8 positions can not reduce yet, and has just avoided aforesaid poor circulation thus.Magnetic valve 9 preferably is installed in before first tap bifurcation after inner bag 1 delivery port, that is is installed between the bifurcation A and inner bag 1 delivery port among Fig. 2, and 8 of pressure inductors can be installed in magnetic valve 9 any water lines afterwards.
The another kind of version of present embodiment, be magnetic valve 9 separately with another pressure inductor as the control signal source, in the case, this another pressure inductor and pressure inductor 8 should be installed in the same water pressure environment, make magnetic valve 9 open, close together with inner bag entering water electromagnetic valve 2.
Though present embodiment is the improvement of making at leakage problem capillaceous, even adopt the pressure releasing device of other structure, present embodiment is suitable for too.
