Abstract

The utility model relates to a side gas inlet natural balance type environmental protection safety type gas water heater. The side lower part of a housing body of the gas water heater is provided with a gas inlet connected with a gas inlet joint and a gas inlet pipe, and an exhaust pipe and the gas inlet pie which are in the same direction are arranged on the housing body. The natural balance type water heater does not use alternating current and is independent of a common smoke flue, and a burner is completely sealed; the natural balance type water heater can be installed in a bathroom, and the problems such as the carbon monoxide poisoning, the oxygen deficiency, the gas leakage, the electric shock, the scalding, the use mistake, etc. of a user can not occur; moreover, water heater which has low production cost and high safety is suitable for bathrooms installed on the sides.

Description

Side air inlet natural equilibrium formula environmental protection and safety type gas heater

Technical field

The utility model belongs to natural equilibrium formula gas heater field.

Background technology

Problems such as anthracemia, anoxic, gas leakage, scald, electric shock electric leakage take place easily in order to solve existing general gas water heater, the applicant had once proposed the fine technical scheme that addresses the above problem of a kind of energy at Chinese patent " balanced type safe environment protection type gas heater " in (ZL03235287.5), practice has also proved the positive effect of this technical scheme to addressing the above problem, and water heater is installed in the bathroom also without any problem.But,, can't satisfy family's needs that the bathroom does not have exterior wall having installed big limitation because it belongs to intake method behind.

Summary of the invention

But the technical problems to be solved in the utility model provides the gas heater of the natural equilibrium formula environmental protection and safety type of a kind of side air inlet.

The utility model solves the problems of the technologies described above with following technical scheme: offer the air inlet that taps into gas joint and air inlet pipe at gas heater housing two side lower parts, blast pipe will be located at the same direction of housing with air inlet pipe during installation.

Side air inlet natural equilibrium formula environmental protection and safety type gas heater of the present utility model, air enters from the case side bottom, discharge the top, enough drafts are arranged, thermal efficiency height without alternating current, does not rely on public flue, and because of housing airtight, problems such as CO poisoning, anoxic, gas leakage, scald, electric shock electric leakage can not take place, and can install in the bathroom, safe in utilization.The user can be according to the actual conditions around the shower wall, optional a gas heater in the present invention and aforementioned invention (ZL03235287.5), can reach burning well, no anoxic, do not have poison, do not have scald, do not have get an electric shock, convenient purpose of safety again.

Description of drawings

Fig. 1 is the structural representation of side air inlet natural equilibrium formula environmental protection and safety type water heater of the present utility model.

Fig. 2 is the air inlet 8 on the utility model water heater side panel 1 and the structural representation of explosion proof door 4.

Smoke exhaust pipe 14 is positioned at the casing top of water heater 16, be connected with exhaust outlet 15, air inlet pipe 22 is connected with the inlet suction port 12 that is positioned at housing side plate 1, parts such as fiery row, heat exchanger, air inlet-outlet pipe, valve body, aqueous vapor linked switch and battery case 13, hot-water line 17, Gas Pipe 20, cold water pipe 21 are installed in the casing, backboard is totally-enclosed, covers with anti-gas-leak with hush panel 7 on the air inlet 8 of both sides.When the user needs left side or right side air inlet, to open a corresponding hush panel 7 and set up inlet suction port 12 and is connected with air inlet pipe 22, usefulness screw 11 is fixing.Be positioned at the water side that connects heat exchanger on the anti-scald water tank 18 of gas heater housing, connect hot water outlet 19 down.Air inlet 8 tops, casing side are provided with explosion proof door 4, have venthole 5 on the explosion proof door 4, and seal up with viscosity tinfoil 6, and the explosion proof door both sides are provided with grooved rail 9, and with fuze (cured continuous line) explosion proof door are hung on hanger 2.The below of grooved rail is provided with caution switch 10, and smoke exhaust pipe 14 stretches out exterior wall 23 through elbow and is connected with anti-blast cap 24, and air inlet pipe 22 is stretched out exterior wall 23, loads onto rodent-proof mesh.

When gas heater took fire work, outdoor air entered from air inlet pipe and participates in burning in the machine, transfers to hot water outlet through anti-scald water tank after cold water is heated.Though can not export hot water equally if anti-scald water tank is not installed, when hot water was exported in igniting again, originally the superheating phenomenon of secondary heating can appear in the hot water in the heat exchanger water pipe, scalds the people easily.Install anti-scald water tank can play superheated water in and regulating action, hot water output is more stable, can not scald the people.

Explosion proof door is the last line of defenses of water heater components and parts after malfunctioning or out of control, when water heater damage or malfunctioning cause out of control, burner can can't quit work and cause over-heat inside dry combustion method fire to suffer from, at this moment, suffer from because of fire and to blow fuze 3 and explosion proof door 4 is fallen automatically close air inlet 8, and close caution switch 10, and cut off general supply and automatic self-closing gas and air enter, allow in the housing moment cause scarce combustion gas, anoxic gas and the fire that suffocates is suffered from.When the time comes, under the situation of cutting off general supply, the user can't reactivate water heater, also can't burn because of anoxic in the housing, can avoid causing bigger accident because of operate miss.Even just in case when gas explosion takes place; the tinfoil of gas breakdown weakness is run out of to the blast pipe on air inlet pipe and top from the pore row of explosion proof door; drawn outdoorly by shunting because of gas, the housing internal gas pressure reduces, and plays the explosion-proof anti-error effect of protection room and personal safety.

The utility model side air inlet natural equilibrium formula environmental protection and safety type gas heater belongs to closed structure, the blast cap that needs the anti-down draught function admirable of configuration, when the smoke exhaust pipe end has used " the anti-down blast cap of horizontal tower shape " that the applicant invented (ZL01252649.5), can conveniently install, can solve the problem that anti-flue gas pours in down a chimney again.

Claims
