Abstract

The utility model relates to a fully-automatic water heater, composed of an electromagnetic valve, a shell, a fire watching sash, a fuel gas quantity regulating knob, a hot water outlet, a fuel gas inlet, a water inlet, a nonfreezing drainage valve, a gas flue, a heat exchanger, a burner, an igniter, a battery box, a micro switch, a water quantity regulating handle, an ignition electrode, an induction needle, an air valve body, etc. The utility model adopts the self priming type electromagnetic valve to replace the traditional differential pressure valve, so the fully-automatic water heater can be started under the condition of low air source pressure, and the adaptability of various fuel gases is enhanced. The utility model also adopts the double ignition electrode, so the ignition rate is high, the deflagration is prevented, and the safety is good.

Description

Fully-automatic water heater

The utility model relates to a kind of water heater, particularly a kind of full-automatic water heater.

Existing water heater generally all is to adopt valve for pressure difference to control the break-make of combustion gas gas circuit.But the air pressure of combustion gas now is lower, and the pressure reduction of generation is obvious inadequately, causes valve opening less, tolerance deficiency, starting difficulty.Particularly adopt the user of artificial coal gas, problem is just more outstanding.In addition existing water heater all is to utilize single-point thermoelectricity limit fire, and the rate of catching fire is not high enough, causes detonation easily.

The purpose of this utility model is to avoid above-mentioned the deficiencies in the prior art part and self-priming magnetic valve of a kind of employing and dual ignition electrode is provided, thereby guarantees still can start under the situation of gas source low pressure, and safe and reliable full-automatic water heater.

The purpose of this utility model can reach by following measure: a kind of full-automatic water heater, comprise housing, see fiery window, gas quantity adjusting knob, hot water outlet, fuel gas inlet, water inlet, non-freezing drainage valve, flue, heat exchanger, burner, igniter, battery case, microswitch, water yield regulating handle, ignitor, inductive needle, it is characterized in that: also have magnetic valve, magnetic valve is loaded on the interior air valve body of blast tube.

The purpose of this utility model can also reach by following measure: ignitor adopts two, is loaded on the both sides of burner.

Fig. 1 is a profile schematic diagram of the present utility model;

Fig. 2 is an internal structure schematic diagram of the present utility model;

Fig. 3 is the mounting structure signal of magnetic valve;

The utility model is described in further detail below in conjunction with accompanying drawing (embodiment):

With reference to Fig. 1, Fig. 2, the utility model is made up of magnetic valve 1, housing 2, the fiery window 3 of sight, gas quantity adjusting knob 4, hot water outlet 5, fuel gas inlet 6, water inlet 7, non-freezing drainage valve 8, flue 9, heat exchanger 10, burner 11, igniter 12, battery case 13, microswitch 14, water yield regulating handle 15, ignitor 16, inductive needle 17, air valve body 18 etc.Magnetic valve 1 is loaded on the interior air valve body 18 of blast tube.Two ignitors 16 are loaded on the both sides of burner, and when sparking, lighting a fire simultaneously in both sides, guarantees to avoid detonation.

With reference to Fig. 3, magnetic valve 1 is made up of valve body 1-1, valve 1-2, spring 1-3, solenoid 1-4, securing member etc.Valve body 1-1 is fixed on the air valve body 18, and communicate with blast tube 19, after starting water valve, water enters from water inlet 7, and the automatic adhesive of 14 meetings is started in fine motion, and pulse igniter 12 sends two high-tension ignitions by two ignitors 16, and export big electric current to solenoid 1-4, make its adhesive, open blast tube 19, the water heater operate as normal.After closing water valve, microswitch 14 disconnects, and solenoid 1-4 discharges, and valve 1-2 resets under the effect of spring 1-3, seals blast tube.

Other parts of this water heater are identical with general water heater, herein no longer narration.

The utility model has following advantage compared to existing technology:

1. adopt self-suction type electromagnetic valve to replace traditional differential magnetic valve, in the situation of gas source low pressure, still can start, improved the adaptability of combustion gas kind.

2. adopted the dual ignition electrode, so the rate height that catches fire can prevent detonation, safe and reliable.

Claims

1, a kind of full-automatic water heater, comprise housing 2, see fiery window 3, gas quantity adjusting knob 4, hot water outlet 5, fuel gas inlet 6, water inlet 7, non-freezing drainage valve 8, flue 9, heat exchanger 10, burner 11, igniter 12, battery case 13, microswitch 14, water yield regulating handle 15, ignitor 16, inductive needle 17, it is characterized in that: also have magnetic valve 1, magnetic valve 1 is loaded on the interior air valve body 18 of blast tube.

2, water heater according to claim 1 is characterized in that: ignitor 16 adopts two, is loaded on the both sides of burner 11.
