Abstract

The utility model relates to an improved gas stove, comprising a mixing chamber, a gas inlet, an air inlet, a lighting device and a shell; wherein the inner loop and the outer loop of the mixing chamber are filled with steel wires. The utility model greatly improves the stability of flame and prevents flame from back burning gas in the mixing chamber; moreover, the are of the air inlet is increased, thus a great deal of air enter the mixing chamber; while the area of the gas inlet remains the same, thus gas is burt in an adequate air environment; at the same time, the height of a support is lowered, so as to reduce radiation and improve thermal efficiency. Gas utilization ration is improved to one time under the situation that other situation is the same, thereby the utility model not only saves energy, lowers environment pollution, but also is able to be utilized in households, eateries and hotels, etc.

Description

A kind of improved gas furnace

Technical field

The utility model relates to Domestic stove, particularly a kind of gas furnace.

Background technology

Existing gas furnace mainly improves flame temperature by increasing the fuel gas supply amount, and when increasing gas quantity, must increase wind supply quantity again, and wind supply quantity can make flame instability greatly even extinguish, therefore general gas furnace all can be provided with deep bead with the control wind supply quantity at air inlet, and the height of gas furnace support is improved.But combustion gas is fully burnt, not only waste the combustion gas resource, but also can produce the carbon black and the pernicious gas of contaminated environment, simultaneously, the support of rising makes the thermal efficiency descend.

Summary of the invention

For addressing the above problem, the purpose of this utility model provides a kind of flame stabilization, sufficient combustion, the improved gas furnace that the thermal efficiency is high.

The purpose of this utility model is achieved in that a kind of improved gas furnace, comprises mixing chamber, air inlet, air inlet, support, ignition device and shell, it is characterized in that: the inner ring and the outer ring of described mixing chamber are filled with steel wire.

Described main air inlet cancellation deep bead becomes without hindrancely every the air port, increases another air-admitting surface to 60～80mm simultaneously ², make the gross area of air inlet increase greatly, make sufficient air enter mixing chamber.

Fulcrum height＜the 15mm of described support.

The utility model can reduce wind speed by at the mixing chamber filler wires, has avoided the impact to flame, improving the stability of flame, can also prevent that flame from firing the combustion gas in the mixing chamber, is very effective flame stabilizer, and, increase air-admitting surface, allow a large amount of air enter mixing chamber, and the air inlet area is constant, combustion gas is burnt under the air ambient of abundance, simultaneously, reduce support height, improve the thermal efficiency thereby reduce heat radiation.Under the situation of other term harmonization, about the combustion gas utilization rate doubles, both saved the energy, reduced environmental pollution again, can be widely used in places such as family, dining room, restaurant.

Fig. 3 is the B-B profile of Fig. 1.

Fig. 4 is the profile of air inlet of the present utility model, air inlet.

The specific embodiment

The utility model is a kind of improved gas furnace, comprises support, ignition device, shell mixing chamber 1, air inlet 2 and air inlet 3,4.Shown in Fig. 1～3, mixing chamber 1 adopts and approaches cast copper is material, and it is fast to utilize it to conduct heat, and quick heating reduces thermal loss and rapid heating gas, and then improves the temperature of flame.Mixing chamber 1 is made up of inner ring 11 and outer ring 12, is connected with two mixing gas ports 6 that vary in size respectively.All be filled with steel wire 5 in inner ring 11 and the outer ring 12, packed density is moderate.As shown in Figure 4,3 places are not provided with traditional deep bead at air inlet, and the diameter with air inlet 4 increases simultaneously, and number reduces, and should be 5 * 4 of φ by 3 * 6 of traditional φ, and air inlet 4 gross areas are by original about 40mm ²Be increased to 80mm ², air inlet 2 big or small constant.Air and combustion gas enter mixing chamber 1 via mixing gas port 6.Support is parts of putting pot, the distance in its fulcrum height decision flame and the bottom of a pan, thereby the effect that influence heat is transmitted, and traditional fulcrum height is about 20mm, and the fulcrum height 13mm of present embodiment.

Claims

1. an improved gas furnace comprises support, ignition device, shell, mixing chamber (1), air inlet (2) and air inlet (3,4), it is characterized in that: inner ring (11) and outer ring (12) of described mixing chamber (1) are filled with steel wire (5).

2. a kind of improved gas furnace according to claim 1 is characterized in that: described air inlet (3) is for without hindrance every air inlet, and the gross area of air inlet (4) is 60～80mm ²

3. a kind of improved gas furnace according to claim 1 is characterized in that: described support fulcrum height＜15mm.
