Description

Household gas burner

The utility model relates to a kind of burner, specifically, relates to a kind of wall-hanging gas fired-boiler of family, gas burner of utensils such as wall-hanging gas heater of being used for.

Use the domestic boiler and the water heater of combustion gas more and more general now.And general at present boiler that uses and water heater mostly are straight-line, combustion air required during burning derives from room air, this combustion system will cause the amount of oxygen in the room air to reduce apace, like this, it is also dangerous both to have polluted indoor environment, in addition, because the room air amount is limited, can make combustion gas because of oxygen supply is not enough can not completing combustion, unburned fuel will directly enter the further pollution that causes indoor and outdoor in the external environment condition.Therefore, in order to reach the purpose of safe handling, an urgent demand domestic boiler and water heater appliances use the combustion system of forcing the supply and exhaust formula.

In view of this, the purpose of this utility model is to provide a kind of gas burner that is used to force supply and exhaust formula domestic boiler and water heater appliances, and the source of supply of combustion air can burn combustion gas in the external world fully, can obviously reduce environmental pollution.

For realizing above-mentioned task, household gas burner of the present utility model comprises body, is the cylindrical shape that binds, and there is an air inlet its underpart; Carrier pipe has entrance and exit, and its outlet is fixedlyed connected with the air inlet of body bottom; Also be included in a plurality of glory holes that body top is offered along periphery.

The advantage of household gas burner of the present utility model is to prevent the indoor and outdoor environmental pollution effectively; Simple in structure.

Below in conjunction with drawings and Examples, the utility model is described in further detail.For the ease of understanding, these accompanying drawings may be out-of-proportion, and in this accompanying drawing, relative parts adopt the corresponding symbol that indicates.

Fig. 1 is the perspective view of the utility model household gas burner:

Fig. 2 is the side view of burner shown in Figure 1:

Fig. 3 is the partial sectional view of burner shown in Figure 1, wherein, with solid line flow deflector is shown and is fixed on unitary side view under this interior state;

Fig. 4 is the perspective view of the flow deflector of burner;

Fig. 5 is the cutaway view of flow deflector shown in Figure 4 along the A-A line.

As depicted in figs. 1 and 2, as the household gas burner 1 of embodiment, the cylindrical shape of its body 2 for binding is welded by upper and

lower bottom surface

10,11 and peripheral wall.Have an air inlet 5 in the bottom of body 2, this air inlet 5 welds with the outlet 7 of carrier pipe 3.Carrier pipe 3 is a tubular-shaped structures, but its inlet 6 flares are convenient to air inlet, and preferably the relative both sides pressing by a seamless tubular goods forms.Offer a plurality of small scale flame hole 4 on the top of body 2, this glory hole 4 distributes equably along the periphery of body 2, preferably by configuration set.Each hole of every group of glory hole 4 can be elongated rectangular, is elongated rectangular hole 41, also can offer a plurality of circular ports 42 equably between the upper surface hole in these elongated rectangular holes 41, in addition, also can offer a plurality of circular ports 42 again below every group of elongated rectangular hole 41.

Fig. 3 to Fig. 5 shows at the body 2 inner flow deflectors 8 that are provided with, and is used for guiding inlet air flow, and this flow deflector 8 is curved, arc opening is towards air inlet 5, its lower end is welded on the bottom surface 11 of body 2, is provided with to such an extent that make arc be in the middle position of body 2 basically, as shown in Figure 3.Preferably the plane is made in the lower end of flow deflector 8, like this, welding easily, and firmly.In order to strengthen the intensity of flow deflector 8, the middle part of flow deflector 8 has along its strip ledge 9 longitudinally, and as shown in Figure 4 and Figure 5, the length of strip ledge 9 terminates in down that preferably transverse plane goes up the position of some slightly.

The utility model household gas burner can adopt stainless steel to make.

During work, be forced to introduce from forcing suction and discharge chimney (not shown), enter the air distribution device (not shown) through the air intake pipe (not shown) as the extraneous air of combustion air, make combustion air be full of this gas burner 1 around.Combustion gas by the ejection of nozzle (not shown) enters carrier pipe 3 from the inlet 6 of carrier pipe 3 together with peripheral combustion air, by body 2 air inlets 5 and carrier pipe 3 outlets 7, the mist that exports 7 ejections from carrier pipe 3 is after flow deflector 8 guiding shuntings, speed reduces, direction changes, and mixes.Then, be discharged to outside the burner, carry out mixing the second time with the combustion air of burner periphery again from glory hole 4.Meanwhile, by the igniting of igniter (not shown), light this well-mixed secondary air mixture.In the present embodiment, because glory hole 4 is by the even thin long rectangular hole 41 of configuration of group, can make flame concentrate relatively and evenly distribute along body 2 peripheries.In addition, the circular port of evenly offering between the upper surface hole of every group thin long rectangular hole 41 42 can be used for the flame of thin long rectangular hole 41 is shifted rapidly mutually, causes every group thin long rectangular hole 41, even all there is flame in each hole, promptly.The circular port of offering between the upper surface hole 42 plays a part to connect flame, makes body 1 first half form a ring-type flame.In addition, a plurality of circular ports 42 of offering below every group thin long rectangular hole 41 can be used for replenishing flame, and so that burning is more abundant.In the present embodiment, glory hole 4 is small-sized hole, and thin and many, like this, can make the combustion gas atomizing of coming out from the hole, helps mixing with combustion air.Therefore, burner structure of the present utility model can make combustion gas and combustion air fully burn.

Though the front can make those of ordinary skill in the art form to description of the present utility model and adopt the mode that is considered to best at present, those of ordinary skill in the art understands and can expect the existence of various conversion, combination and the equivalent of above-mentioned specific embodiment.Therefore, the utility model is not limited to cited embodiment here, but is limited by the essence of claim of the present utility model and all embodiment that ask for protection in the scope.
