Abstract
The utility model relates to the field of domestic appliances, in particular to a gas water heater. The gas water heater with seal burning comprises an outer shell, a burner, a heat exchanger, a gas inlet channel, a water inlet pipe, a gas pipe, a water outlet pipe and a gas electronic proportion valve, wherein the burner is a seal burner; a draught flue is sleeved in the gas inlet channel which is divided into an inner layer of air current channel and an outer layer of air current channel by the draught flue; the inner layer of air current channel is communicated with a gas outlet of the heat exchanger while the outer layer of air current channel is communicated with a burner through a pipeline; and exhaust blowers are both arranged in the pipeline between the burner and the heat exchanger and the fume exhaust pipe. When the gas water heater with seal burning operates, the needed oxygen is supplied from the outer layer of air current channel, and the smoke gas generated by the burning is exhausted to the outdoor from the inner layer of air current channel so as not to consume and pollute the indoor air, therefore, the gas water heater with seal burning has security and reliability, can be installed in a bathroom and has wide popularization application value.
Description
Technical field
The utility model relates to household appliance technical field, relates in particular to a kind of gas heater.
Background technology
Along with people's living standard is more and more higher, 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.At present the water heater that uses on the market has more the energy difference 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 be subjected to vast consumer's favor.
Existing gas heater mostly is Flue Gas Water Heater greatly, 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, initial igniter and microswitch control, ignition combustion device.Combustion gas is in the combustion chamber internal combustion, and the heat of generation heats water by heat exchanger, and hot water flows out continually from delivery port.Because the combustion chamber blow-by of this class water heater, water heater is installed in indoor, needed oxygen is also taken from indoor during the water heater burning, the waste gas that burning is produced is arranged to outdoor by flue, so this class water heater can not be installed in the bathroom, must install by locellus, the CO that imperfect combustion produces can stay within, and brings potential safety hazard.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of gas heater of sealing combustion, and the combustion chamber of this water heater is a Seal Design, and required air and exhaust gas discharged during burner operation all are communicated with outdoor by pipeline, and be more safe and reliable.
The utility model is achieved in that a kind of gas heater of sealing combustion, comprise shell, burner, heat exchanger, air intake duct, water inlet pipe, Gas Pipe, outlet pipe and combustion gas electronics proportioning valve, described air intake duct is arranged on the top of shell, described water inlet pipe, Gas Pipe and outlet pipe are arranged on the bottom of shell, water inlet pipe is connected with the water inlet of heat exchanger by inlet pipeline, Gas Pipe is connected with the fuel gas inlet of burner by air inlet pipeline, the heat outlet of burner is connected with the air inlet of heat exchanger by pipeline, the delivery port of heat exchanger is connected with outlet pipe by outlet pipeline, described combustion gas electronics proportioning valve links to each other with air inlet pipeline with inlet pipeline respectively, described burner is the sealing combustion device, be set with exhaust uptake in the described air intake duct, described exhaust uptake is divided into inside and outside two-layer gas channel with air intake duct, described internal layer gas channel is communicated with the gas outlet of heat exchanger, described outer gas flow passage is communicated with the burner sealing by pipeline, all is provided with air exhauster in pipeline between burner and the heat exchanger and the exhaust uptake.
Have observation window with the burner corresponding position on the described shell.
Burner seals in the gas heater of the utility model sealing combustion, air intake duct and exhaust uptake are combined to form inside and outside two-layer gas channel, the oxygen that needs during the water heater operation is supplied from the outer gas flow passage, the flue gas that the burning back produces is discharged to outdoor from the internal layer gas channel, so it neither consumes room air, also not polluting, is a kind of safe and reliable gas heater that can be installed in the bathroom, has application value widely.
Description of drawings
Fig. 1 looks schematic diagram for the gas heater structure master of the utility model sealing combustion;
Fig. 2 is that the X of Fig. 1 is to schematic diagram;
