Abstract
A self-controlled electrothermal steam boiler is composed of casing, boiler body, electric heater, water inlet, steam outlet, safety valve and electric heating controller consisting of probe, drive circuit board, transformer, AC contactor, buzzer and operating panel. An interrupter is arranged between the buzzer and the alternating current contactor, and the interrupter consists of a coil and a metal spring piece. When the water level in the furnace body is lower than the warning line, the buzzer alarms, and the breaker automatically cuts off the power supply of the electric heater, so that the automatic protection effect is achieved, and accidents are avoided. And after water is supplied, power supply is automatically recovered. The utility model is widely used in the occasions of clothes ironing, sanitation and disinfection, food cooking, etc., and is safe and reliable.
Description
The utility model relates to a kind of electric steam boiler, particularly has automaton, has the electric steam boiler of safety protection function.
Electric steam boiler employing electric heater makes the water generates high-temperature steam in the boiler, is widely used in occasions such as clothes ironing, disinfecting, food boiling, and large-scale electric steam boiler then is used for industrial production.The electric steam boiler that uses generally is made up of boiler, electric heater and electrical control part at present, for preventing that the water in the boiler from being dryouied, autoalarm is housed usually.When the water surface in the boiler was lower than the detecting head position, electric control part branch provided signal, and alarm is sounded, and reminded the operator to hasten to handle.But this moment, electric heater still heated, and in time handled as the operator, and then electric heater may burn out or take place other accident, therefore, warning device is only arranged, and strictness is said and be dangerous.
The purpose of this utility model is to overcome weak point of the prior art, and a kind of safe and reliable, self-controlling electrothermal formula steam boiler with automatic protection functions is provided.
The technical solution of the utility model is, self-controlling electrothermal formula steam boiler mainly is made up of shell, body of heater, electric heater, water inlet, venthole, safety valve and electrical heating control section, and this control section comprises detecting head, driver circuit plate, transformer, A.C. contactor, buzzer and guidance panel again.Improvements are, contain circuit breaker in the described control section, and this circuit breaker is connected between buzzer and the A.C. contactor.When detecting head provides signal, in the time of buzzer warning, circuit breaker work makes the power supply of the automatic sever supply electric heater of A.C. contactor, and electric heater stops heating; After the boiler middle water level raise, circuit breaker resetted, and A.C. contactor is the electric heater power supply again automatically.
As further improvement of the utility model, described circuit breaker is made up of coil and the metal spring sheet that is arranged in coil magnetic field, and whether switching in the coil is changing the position of spring leaf, is whether electric heater powers with the decision A.C. contactor.
The utility model when boiler is anhydrous, is not only reported to the police automatically owing to be provided with circuit breaker and buzzer, but the power supply of automatic disconnection electric heater also prevents that heater from burning out or other accident takes place, and is therefore safe and reliable.After adding water, again can automatic recovery of power supply, easy to use.
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a circuit connecting relation schematic diagram in the utility model electrical heating control section.
As figure, body of heater 4 and electrical heating control section 8 are installed in the shell 1, guidance panel 9 is contained in the front of shell.The bottom of body of heater 4 is provided with electric heater 2, and the top is provided with water inlet 5, venthole 6 and An Jin valve 7.Detecting head 3 is inserted by the body of heater top, and its head extends the position that bottom of furnace body is higher than electric heater.In the electrical heating control section, the 12V output of transformer 11 links to each other with driver circuit plate 12, and the 220V output links to each other with A.C. contactor 10, and is electric heater power supply in the body of heater 4 by the output of A.C. contactor.Have lead to link to each other with detecting head in the body of heater in the driver circuit plate 12 respectively, link to each other with buzzer 13, circuit breaker 14 is connected between buzzer 13 and the A.C. contactor 10.Circuit breaker is made up of coil and the metal spring sheet that is arranged in coil magnetic field.When detecting head provides anhydrous signal,, make the circuit breaker coil electricity simultaneously by driver circuit plate control buzzer warning; the metal spring sheet changes the position; automatically cut off the 220V power supply that A.C. contactor is supplied with electric heater, play automatic protective effect, avoid electric heater to burn out.After the boiler middle water level raises, the detecting head ring off signal, the circuit breaker reed of being hit by a bullet resets, and A.C. contactor then recovers to power to electric heater.
Claims (2)
1, a kind of self-controlling electrothermal formula steam boiler, comprise shell, body of heater, electric heater, water inlet, venthole, safety valve and electrical heating control section, this control section comprises detecting head, driver circuit plate, transformer, A.C. contactor, buzzer and guidance panel again, it is characterized in that, contain circuit breaker in the described control section, this circuit breaker is connected between buzzer and the A.C. contactor.
By the described self-controlling electrothermal formula of claim 1 steam boiler, it is characterized in that 2, described circuit breaker is made up of coil and the metal spring sheet that is arranged in coil magnetic field.
