Abstract

Disclosed is a gas-fired stove which solves the problems for existing gas-fired stoves of nonuniform distribution of pressure, inconsistent combustion flame height, a small air inlet section, and existing dead corners of air flow. The air inlet of the premixing chamber is like a streamlined bell-mouth, and nozzle retaining nuts on the end of the gas-fired stove has a suspension type; the outlet of the premixing chamber has a semi-open type. The air inlet section is enlarged so that the burning gas and air can be fully mixed in the premixing chamber. The outlet of the premixing chamber is semi-open type, thus after the mixture gas enters a stove basin, a mobile pressing head quickly goes down, so that the mixture gas can diffuse to the whole stove basin with a more uniform pressure. Therefore, the flame height of the stove face is similar, so that the burning gas can fully burn, to save burning gas.

Description

Gas stove

The utility model belongs to a kind of stove and accessory, particularly a kind of gas furnace.

Existing gas furnace, the union end of its premixer and stove basin is a vertical plane, so just make exit, stove basin premixer with away from the pressure distribution inequality in exit, premixer, during burning, flame height is not to unanimity.The air intlet of premixer is not a streamlined, and the cross section is little, is the moving dead angle of free air-flow to exist.

The purpose of this utility model is to solve above-mentioned existing problem, provides a kind of combustion gas can fully mix with air, the uniform gas furnace of stove basin internal pressure.

The utility model be achieved in that on the lower sides of stove basin with the stove basin in communicate and be welded with the premixer, the air intake place of premixer is the streamlined bell mouth shape, and the nozzle retaining nut of end is a suspension type; Premixer's outlet is semi-open-type.At stove basin upper end edge boiler face is installed.

Advantage of the present utility model is, because combustion gas is to spray into the premixer under certain pressure, and air is negative pressure backflow and the inflow mixing chamber that forms when relying on combustion gas to spray into, the air intake place of premixer adopts streamlined horn-like, and the nozzle retaining nut of end is a suspension type, increased the air intake cross section, combustion gas can be mixed in the premixer fully with air; Premixer's outlet is semi-open-type, and mist enters stove basin dynamic head and descends rapidly, makes mist be diffused into whole stove basin with uniform pressure, thereby makes the flame height unanimity of boiler face.Combustion gas can fully be burnt, save combustion gas.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A of Fig. 1 is to view.

Describe in detail below in conjunction with accompanying drawing:

As shown in the figure, communicate and be welded with premixer 4 on the lower sides of stove basin 3 with in the stove basin, air intake 6 places of premixer 4 are the streamlined bell mouth shape, and the nozzle retaining nut 5 of end is a suspension type, the outlet 2 of premixer 4 is a semi-open-type, at stove basin 3 upper end edges boiler face 1 is installed.During use, the premixer can fully make combustion gas mix with air, in the stove basin everywhere pressure reach unanimity, thereby make the flame height unanimity of boiler face, combustion gas is fully burnt.

Claims (1)

1, a kind of gas furnace communicates and is welded with the premixer on the lower sides of stove basin with in the stove basin, at stove basin upper end edge boiler face is installed; It is characterized in that the air intake place of premixer is the streamlined bell mouth shape, and the nozzle retaining nut of end is suspension type, the outlet of premixer is half worn-out open type.
