Abstract

The utility model relates to a gas warming apparatus for domestic heating; a flow choking device arranged in a heat transferring casing is used for extending the process of the combustion of hot gas and increasing the contacting (heat transferring) time of the hot gas and a casing wall. The gas warming apparatus has the advantages of simple and compact structure, low cost and price, the integral completion of combustion and heat supply, favorable effect of heat utilization and no pollution on indoor air.

Description

Gas warm apparatus

The utility model belongs to the heat supply heating system, particularly a kind of fuel gas heating apparatus that is suitable for family expenses.

At present, household warming mostly is space heater or the stove of warming oneself by a fire.Space heater sanitation and hygiene, convenience, but power consumption height, the cost height; The furnace structure of warming oneself by a fire is simple, the heat utilization efficiency height, but the carbon dioxide packing gas that the burning back generates pollutes room air, and when burning was insufficient, the carbonic oxide that is generated had the danger that causes indoor occupant to poison.As directly being provided with on the stove of warming oneself by a fire waste gas is discharged the piping outside the house, its thermal loss is too big again.

China's utility model discloses the domestic gas hot air heater of a kind of CN2083718U, by gas-fired heater, the two-stage heat exchanger of annular heating calancria is housed, and air blast and the attached member that helps constitute, and air heats back inlet chamber inner radiator in the I and II heat exchanger.Its subject matter is complex structure, the cost height, and price is more expensive.

The purpose of this utility model is by fuel gas buring, heat supply (heat transfer) one being finished, provided a kind of simple in structure, compact, sanitation and hygiene, the high and cheap domestic gas warmer of heat utilization efficiency.

The technical solution of the utility model is the housing that includes heat transfer usefulness, is contained in the gas furnace of bottom in the housing chamber, the waste gas mozzle on housing top, on this sidewall of shell with the bearing of corresponding peep hole of gas furnace and bottom thereof.In the housing chamber, be provided with choke apparatus with matching.

Choke apparatus is corresponding, wrong being installed in order on the inner walls and the perpendicular spoiler of combustion flame.This spoiler can prolong the flow process of hot gas in housing, increases itself and the contacting of shell wall (conduct heat, heat radiation) time.This choke apparatus also can be to be contained in the endoceliac conveyor screw of shell, and spirochetal outer rim is connected with the housing cavity wall, forms helical duct.

Shell wall is thin more, and its heat transfer radiating effect is good more, but its intensity can be influenced, for this reason, also is provided with reinforcement on the sidewall of housing.

Waste gas mozzle lower port communicates with housing top, and its upper end outlet is outdoor.

The utility model compared with prior art has simple and compact for structure, cost and cheap, and burning, heat supply (heat transfer) is integrated, direct heat transfer, heat utilization efficiency is high and do not pollute the advantage of room air.

Accompanying drawing drawing of the present utility model is described as follows:

Fig. 1: front view of the present utility model.

Fig. 2: the A-A cutaway view among Fig. 1.

Below in conjunction with embodiment (accompanying drawing) the utility model is further described:

Shown in Fig. 1-Tu, the lower port 2 of waste gas mozzle 1 of the present utility model is communicated with the top of housing 3, and its upper port is contained in outdoor.On the sidewall outer surface of housing 3 reinforcement 4 is arranged, tighten up in its bottom 4 symmetrical bearings 8 are housed, the gas furnace 7 of band automatic ignitor 10 and Gas Pipe 9 is equipped with in the bottom, chamber within it.Air enters gas furnace 7 from the lower bottom part of housing 3.The peep hole 6 of band cloche is located on the sidewall of housing 3 corresponding to gas furnace 7.On spoiler 5 correspondences, staggered, the overlapping orderly inwall that is contained in housing 3, make inner chamber form the burning hot gas passage of S shape.

Claims

1, a kind of fuel gas heating apparatus includes shell originally, is located at the gas furnace of bottom in the housing, and the waste gas mozzle on top, peep hole and the bottom support bracket thereof on the sidewall is characterized in that being provided with choke apparatus with matching in the housing chamber.

2, fuel gas heating apparatus according to claim 1, it is characterized in that described choke apparatus be corresponding, staggered, be contained on the inner walls and the perpendicular spoiler of flame in order.

3, to show 1 or 2 described fuel gas heating apparatus according to right, it is characterized in that also being provided with reinforcement on the sidewall of described housing.
