Heating and bathing gas water heater for double volume and condensation heat exchange system

Abstract

The invention discloses a heating and bathing wall-mounted gas furnace for a 'double volume + condensation heat exchange system', which comprises a shell, a microcomputer controller, a normally closed solenoid valve, a combustor, a first combustion chamber, a second combustion chamber, a lower honeycomb-shaped or parallel circular tube grate-shaped condensation volume heat exchanger and the like so as to form a heating and bathing combustor which has the advantages of forcedly changing hot water flow rule, fully utilizing heat energy, fully combusting gas, having large heat exchange area, long stroke and no resistance, not needing cleaning a flue in lifetime, supplying heating and bathing domestic water, and singly supplying bathing water in summer. The heating and bathing wall-mounted gas furnace saves energy by 30 percent and saves cost by about 60 percent than concentrated heating, saves energy and cost by over 60 percent than a pipeline type wall-mounted gas furnace, saves energy and cost by about 65 percent than the electric energy, and saves cost by 40 percent than honeycomb briquette heating. Because the gas furnace is ignited by gas electronically, so the heating can be started and stopped at any time, and the trouble of making a fire by coal and briquettes and pollution are eliminated; therefore, the heating and bathing wall-mounted gas furnace is an energy-saving and clean heating and bathing water heater which can be opened and closed at any time or fixed time.

Description

1. Technical field [0001] The invention relates to a gas-fired heating and bathing water heater. Furnace type: wall-mounted furnace and floor-standing furnace. It is a heating and bathing water heater for families, offices and public places. It is a kind of water heater with microcomputer automatic control or manual control. The gas heating and bathing water heater controlled by the temperature and each indicator light and five keys is a double-volume plus condensing heat exchange system; the internal pressure of the double-volume heat exchange is equal to the atmospheric pressure, so it is absolutely explosion-proof, and the internal expansion tank can also be made larger than Atmospheric pressure, plus pressure gauge and safety valve; gas burns once and then burns again, so there is no carbon monoxide; double-volume large-area heating, no resistance to combustion, no need to clean the flue for life; there is a water pump to enhance hot water flow and heat exchange , and can ...

Problems solved by technology

[0002] At present, central heating, briquette stoves, briquette soil heaters or coal fire chimneys are mostly used for heating in winter. In recent years, movable liquid fuel, fuel oil and pipeline gas wall-hung boilers have been introduced from abroad, and 30% of central heating energy is wasted. Above, this is because there is usually no one in the family residence or office for 1 / 3-1 / 2 of the time, no heating is required, and the cost is higher; honeycomb coal stove, honeycomb coal soil heater or coal fire chimney for heating, the fire will be turned off if you are not careful , the labor intensity is high, it pollutes the environment, it is easy to gas poisoning, and it also consumes energy for a long time; the movable liquid and oil heating furnaces are local, and the doors and windows need to be often opened for ventilation, otherwise the indoor lack of oxygen, pipeline gas Wall-hung boilers have low heat utilization and high prices
