Abstract

The utility model relates to the field of household appliances, in particular to a gas water heater. An internal-pressure monitoring security-type gas water heater comprises a housing, a burner, a heat exchanger, an exhaust flue, a water inlet pipe, a gas pipe, a water outlet pipe and a gas electronic proportioning valve, wherein the air outlet of the heat exchanger is communicated with the exhaust flue; the water outlet of the heat exchanger is communicated with the water outlet pipe through a water outlet pipeline; the gas electronic proportioning valve is connected with a water inlet pipeline and an air inlet pipeline respectively; the gas heater further comprises an air inlet pressure gage and a burner pressure gage; the air inlet pressure gage is communicated with the front part of the air inlet of the gas pipe; and the burner pressure gage is communicated with the air inlet of the burner. The internal-pressure monitoring security-type gas water heater adopts the two pressure gages to compare the readings, and the leakage of the air inlet pipeline can be shown when the readings are inconsistent, so that gas leakage can be found immediately and the safety of lives and property of users can be guaranteed. The gas water heater has a simple structure, and is convenient to use.

Description

Inspection of inner pressure safety-type gas heater

Technical field

The utility model relates to household appliance technical field, relates in particular to a kind of gas heater.

Background technology

The living standard of Along with people's is increasingly high, and everybody has had further requirement to the personal hygiene problem, more than general of particularly bathing aspect has been accomplished once, so sanitary bath equipment has been had higher requirement.It is different that the water heater that uses on the market at present has more the energy of use, roughly is divided into three kinds of electric heater, solar water heater and gas heaters.Wherein gas heater is with imflammable gas: liquefied petroleum gas, artificial coal gas, natural gas etc. are fuel carries out Fast Heating to water water heater; Have thermal efficiency height, go out hot water fast, continue constant temperature, regulate easily, plurality of advantages such as volume is little, easy for installation, more and more receive vast consumer's favor.

Existing gas heater is Flue Gas Water Heater mostly, and basic structure mainly is made up of valve body assembly, burner, heat exchanger, safety device etc.Valve body assembly is being controlled the working procedure of whole water heater, and it comprises water valve, air valve, microswitch and igniter etc.When using water heater, must open gas valve and water intaking valve earlier.When opening water valve, the current inductor is sensed current, igniter and microswitch control, ignition combustion device.Combustion gas is internal combustion in the combustion chamber, and the heat of generation heats water through heat exchanger, and hot water flows out from delivery port continually.Existing gas heater does not have any combustion gas to reveal safety alarm device usually; The simple normal operation that relies on daily maintenance to guarantee water heater; For average family, generally can not do conventional maintenance; Can't detect gas heater and whether leak gas, not have safety guarantee, thus the time regular meeting gas poisoning takes place.

Summary of the invention

The utility model technical problem to be solved provides a kind of inspection of inner pressure safety-type gas heater, this water heater.

The utility model is achieved in that a kind of inspection of inner pressure safety-type gas heater; Comprise shell, burner, heat exchanger, exhaust uptake, water inlet pipe, Gas Pipe, outlet pipe and combustion gas electronics proportioning valve; Said exhaust uptake is arranged on the top of shell, and said water inlet pipe, Gas Pipe and outlet pipe are arranged on the bottom of shell, and water inlet pipe is connected with the water inlet of heat exchanger through inlet pipeline; Gas Pipe is connected with the fuel gas inlet of burner through air inlet pipeline; The heat outlet of burner is connected with the air inlet of heat exchanger, and the gas outlet of heat exchanger is connected with exhaust uptake, and the delivery port of heat exchanger is connected with outlet pipe through outlet pipeline; Said combustion gas electronics proportioning valve links to each other with air inlet pipeline with inlet pipeline respectively; This gas heater also comprises air inlet pressure gauge and burner pressure gauge, and said air inlet pressure gauge is communicated with before the air inlet of said Gas Pipe, and described burner pressure gauge is communicated with on the fuel gas inlet of burner.

Have observation window with the burner corresponding position on the described shell.

Described side wall of outer shell offers louver(-vre).

The utility model inspection of inner pressure safety-type gas heater through two pressure gauges relatively when reading is inconsistent, explains that air inlet pipeline has leakage, can find the combustion gas leakage problem at once, and is simple in structure, easy to use, ensured user's the security of the lives and property.

Description of drawings

Fig. 1 looks sketch map for the utility model inspection of inner pressure safety-type gas heater structure master;

Fig. 2 is the utility model structural upright sketch map.

Among the figure: 1 shell, 2 burners, 3 heat exchangers, 4 exhaust uptakes, 5 water inlet pipes, 6 Gas Pipe, 7 outlet pipes, 8 observation windows, 9 louver(-vre)s, 10 combustion gas electronics proportioning valves, 11 air inlet pressure gauges, 12 burner pressure gauges.

The specific embodiment

Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment only to be used to the utility model is described and be not used in the restriction the utility model scope.Should be understood that in addition those skilled in the art can do various changes or modification to the utility model after the content of having read the utility model statement, these equivalent form of values fall within the application's appended claims institute restricted portion equally.

Embodiment 1

Like Fig. 1, shown in 2; A kind of inspection of inner pressure safety-type gas heater; Comprise shell 1, burner 2, heat exchanger 3, exhaust uptake 4, water inlet pipe 5, Gas Pipe 6, outlet pipe 7 and combustion gas electronics proportioning valve 10; Said exhaust uptake 4 is arranged on the top of shell 1, and said water inlet pipe 5, Gas Pipe 6 and outlet pipe 7 are arranged on the bottom of shell 1, and water inlet pipe 5 is connected through the water inlet of inlet pipeline with heat exchanger 3; Gas Pipe 6 is connected through the fuel gas inlet of air inlet pipeline with burner 2; The heat outlet of burner 2 is connected with the air inlet of heat exchanger 3, and the gas outlet of heat exchanger 3 is connected with exhaust uptake 4, and the delivery port of heat exchanger 3 is connected with outlet pipe 7 through outlet pipeline; Said combustion gas electronics proportioning valve 10 links to each other with air inlet pipeline with inlet pipeline respectively; This gas heater also comprises air inlet pressure gauge 11 and burner pressure gauge 12, and said air inlet pressure gauge 11 is communicated with before the air inlet of said Gas Pipe 6, and described burner pressure gauge 12 is communicated with on the fuel gas inlet of burner 2.
