Background technology
At present, the application of water dispenser is widely used, and the employed control device of water dispenser, its function singleness, dangerous, the user drinks not boiled water easily, as Chinese patent 02248373.X number, open day is on September 17th, 2003, name is called " water dispenser control device ", its principal feature is: between the power input of water dispenser and thermoelectric heating device earth leakage protective device is set, limit warm restrictor, thermostat, attemperating unit is by temperature controller one, the safety type temperature controller, temperature controller two constitutes, earth leakage circuit-breaker is arranged on the phase line end of incoming cables of AC power, one end of thermal cut-off is connected the output terminal of earth leakage circuit-breaker, the other end and temperature controller, power light also connects; The other end of temperature controller and the other end of temperature indicator also connect; Safety type temperature controller, temperature controller series connection are connected across the two ends of thermoelectric heating device.The control device of this water dispenser can prevent electric leakage, 1), but still in following shortcoming: owing in the control device automatic control electromagnetic valve is not set, can not control the function of its boiling water flow, when water is not opened, still can open and drink, so people often drink the warm water of cold and hot mixing, do not meet the requirement of drinking water hygiene; 2), the break-make of heating arrangement directly by switch control, promptly is not provided with conversion equipment, makes in its heating process and can not control heating automatically, uses inconvenience.
The utility model content
In order to solve the defective that exists in the above-mentioned prior art, the purpose of this utility model is to provide a kind of can guarantee water hygiene, water dispenser automaton safe, easy to use.
The technical solution of the utility model is: the automaton of water dispenser, between the power input of water dispenser and electro-heat equipment and connect a control circuit, be in series with switch on the described control circuit respectively, the normally closed type temperature controller, normally closed type temperature controller and A.C. contactor, described A.C. contactor is provided with normally closed switch and normal open switch, the input end of described normally closed switch connects the input end of switch, the output terminal of normally closed switch connects the input end of solenoid valve, the output terminal of described solenoid valve connects the output terminal of control circuit, the input end of described switch also connects a red light input end, the red light output terminal connects the green light input end, the green light output terminal is connected with the output terminal of control circuit, the input end of one temperature controller open in usual is connected with the input end of switch, its output terminal is connected across normally closed switch respectively and solenoid valve joins joining between the end of end and red light and green light, and the normal open switch on the described A.C. contactor is located at the input end of electro-heat equipment.Described A.C. contactor is provided with a normally closed contact and three normally opened contacts.Above fuse of input end series connection of described heating arrangement.Described normally closed type temperature controller and temperature controller open in usual are radiator valves, and another normally closed type temperature controller is the warm Current limited Control device of limit.Described normally closed type temperature controller, temperature controller open in usual are to be close on the outer wall of inner bag.
The beneficial effects of the utility model are:
1), since control device in be provided with automatic control electromagnetic valve, can control the function of its boiling water flow, when water is not opened, valve closing, water can not flow out.So people often drink the boiling water through the high temperature heating, meet the requirement of drinking water hygiene;
2), the break-make of heating arrangement directly by the normally closed switch and the normal open switch control of A.C. contactor, makes in its heating process and can control heating automatically, uses inconvenience;
3), the warm limiting fuse of one limit is set, can effectively protects electro-heat equipment, thereby improve its safety in utilization at the input end of heating arrangement.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is another embodiment of the present utility model.
Embodiment
As shown in Figure 1: the automaton of water dispenser, between the power input of water dispenser and electro-heat equipment H and connect a control circuit, be in series with K switch 1 on the control circuit respectively, normally closed type temperature controller A, normally closed type temperature controller B and A.C. contactor KM, described A.C. contactor KM is provided with normally closed switch KM1 and normal open switch KM2, the input end of described normally closed switch KM1 connects the input end of K switch 1, the output terminal of normally closed switch KM1 connects the input end of solenoid valve DJ, the output terminal of described solenoid valve DJ connects the output terminal of control circuit, the input end of described K switch 1 also connects a red light L1 input end, red light L1 output terminal connects green light L2 input end, green light L2 output terminal is connected with the output terminal of control circuit, the input end of one temperature controller C open in usual is connected with the input end of K switch 1, its output terminal is connected across normally closed switch KM1 respectively and solenoid valve DJ joins joining between the end of end and red light L1 and green light L2, and the normal open switch KM2 on the described A.C. contactor KM is located at the input end of electro-heat equipment H.Described A.C. contactor KM is provided with a normally closed contact and three normally opened contacts.The input end of heating arrangement H is provided with a fuse FU.Described normally closed type temperature controller A and temperature controller C open in usual are that radiator valve and normally closed temperature controller B are the warm Current limited Control devices of limit.Temperature controller A, B and C are close on the outer wall of inner bag.
Be the utilization structure figure under the 220V power supply of the present utility model as shown in Figure 2.
Principle of work: because normally closed type temperature detect switch (TDS) A and normally closed type temperature detect switch (TDS) B and ac contactor coil are series connection, therefore, during heating, when normally closed type temperature controller A takes place when malfunctioning, temperature is too high, normally closed temperature controller B will automatic cutout, and contactor KM coil discharges because of dead electricity, and normal open switch KM2 and normally closed switch KM1 reset, thereby cut off the electricity supply, make heating arrangement stop H and end heating, and red light L1 extinguishes, green light L2 is bright.Simultaneously, because temperature controller C open in usual and solenoid valve DJ constitute control minable water yield automatically, temperature controller C open in usual detects the water temperature in the water courage automatically, when water temperature reaches boiling point, temperature controller C closure open in usual, solenoid valve DJ opens, and the water in the water courage can be drunk for the people, when the Wen Wei that turns one's coat reaches boiling point, normally closed switch KM1 and temperature device open in usual still are in open mode, make closed electromagnetic valve, the water in the water courage can not flow out, thereby can effectively guarantee drinking water hygiene.At last, K switch 1, normal open switch KM2 and normally closed switch KM1 constitute conversion equipment, when the water courage is anhydrous, must press K switch 1 to water filling one side, K switch 1 disconnects, and contactor coil KM dead electricity discharges, and normal open switch KM2 and normally closed switch KM1 are in reset position, thereby heating arrangement H is continued out, and it is electric that solenoid valve DJ is got, and opens water filling port automatically, and water is injected inner bag.Thereby reach temperature automatically controlled, control water.
