Abstract

The utility model provides to a secondary air-preheating combustion accelerating device for gas ranges, relating to the components of a gas range, especially a special air-preheating combustion accelerating device for supplying secondary hot air. The waste heat of burned gas is used sufficiently for preheating the secondary air for burning the fuel gas sufficiently and improving the temperature of combustion flame and the heat efficiency. The secondary air-preheating combustion accelerating device for gas ranges can be widely used in various gas ranges and is characterized in that a wind inlet disk, a wind outlet disk, a wind shield ring and a preheating chamber are made into a whole, and then clamped and sheathed on the fire head and the fire hole of a gas range.

Description

Secondary air-preheating combustion accelerating device for gas range

The utility model relates to the gas-cooker parts.Particularly a kind of for making fuel completing combustion supply with the special-purpose air preheated-combustion-supporting device of secondary hot-air.

Gas-cooker in use, combustion gas sprays at a high speed from nozzle, relies on its ejector action that outside air is drawn in the mixing tube through air door.Combustion gas fully mixes with primary air in mixing tube, and the fire hole from duration and degree of heating flows out burning then.Simultaneously, all there is auxiliary air to participate in burning with the centre around the duration and degree of heating.But now mixing with the secondary of air for combustion gas with gas-cooker all is the nature mixed form.This mixed form is owing to fail the air that institute's secondary mixes is carried out preheating, and flame temperature produces the side effect that reduces during therefore to burning, has reduced the thermal efficiency.

At the problems referred to above, the purpose of this utility model is to provide a kind of combustion-supporting that makes the auxiliary air preheating of gas-cooker, is fastened on the height of anger, to improve the efficiency of combustion of gas-cooker.

The utility model is realized in the following way: it is made of supplying air disc 1, air-out dish 2, air baffle ring 4, preheating chamber 5, annexation is as follows between each member: air-out dish 2 is fastened in the top of duration and degree of heating 3, supplying air disc 1 is fastened in the root of duration and degree of heating 3, and constitutes the annular preheating chamber 5 of a sealing between supplying air disc 1 and the air-out dish 2; 2 edges are connected with air baffle ring 4 at the air-out dish, and this air baffle ring 4 is curved to the inclination of duration and degree of heating 3 central authorities; Above-mentioned supplying air disc 1, air-out dish 2, air baffle ring 4, preheating chamber 5 are made into an entire card and are enclosed within on the duration and degree of heating 3, fire hole of gas-cooker; Described supplying air disc 1 is a ring bodies, is arranged with a plurality of air intake grooves on its anchor ring; Described air-out dish 2 is ring bodies, is arranged with a plurality of air outlet holes on its anchor ring.

The utility model is simple in structure.Make full use of the waste heat preheating auxiliary air of fuel gas buring, combustion gas is fully burnt, improved the temperature of combustion flame, improved the thermal efficiency, both saved the energy, reduce waste gas again and produce.Can be widely used in various gas kitchen ranges.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is that the utility model is fastened in the structural representation on the gas-cooker duration and degree of heating 3;

Fig. 2 is the structural representation of air-out dish 2;

Fig. 3 is the structural representation of supplying air disc 1.

With reference to Fig. 1-Fig. 3, the utility model is fastened on the gas-cooker duration and degree of heating 3, during burning, natural air enters preheating chamber 5 from the air intake groove of supplying air disc 1, because the conduct radiation of duration and degree of heating 3 combustions heat, air heat in the preheating chamber 5, hot-air enters duration and degree of heating 3 centres, the effect that air baffle ring 4 plays radiation of heat equally and keeps out the wind from the air outlet hole of air-out dish 2.Under the acting in conjunction of air-out dish 2 and air baffle ring 4, the air of outflow further heats, and the auxiliary air that passes through preheating is provided for the flame of gas-cooker duration and degree of heating 3, promotes the abundant burning of combustion gas.
