The utility model is intended to overcome above-mentioned the deficiencies in the prior art, thereby provides the family expenses catamaran type that a kind of volume is little, the thermal efficiency is high energy-conservation gas range.

The total inventive concept of the utility model is: the structure of the family expenses catamaran type gas range by changing prior art, and the combustion chamber is placed in the housing, it directly not open to the external world, thereby reduces scattering and disappearing of heat, the raising thermal efficiency.

Specifically, the purpose of this utility model is to be reached by following technical scheme: the utility model comprises shell, a combustion gas house steward who is used to insert combustible gas, two cover air throttles, the sparking knob, spray combustion plate, it is characterized in that: it also comprises a total mixed air vessel, this mixed air vessel is positioned at the stove central enclosure, its termination is gone into the combustion gas house steward and is used to suck the air hose of air, the other end is then by two air throttles, the sparking knob is linked into the combustion chamber of the left and right sides respectively, described combustion chamber is a peviform, be positioned at kitchen range left and right sides housing, inner surface has muscle, by lightweight, porous, the refractory material that heat-proof quality is good is made, and there is a heat insulation rubber cushion that is used for the supporting pot body that outwards protrudes at its edge, upper end and is positioned at one under this heat insulation rubber cushion and the extraneous exhaust smoke hole that interlinks, the spray combustion plate that its bottom is a porous.

The utility model with structure like this is when work, the pot body places on the combustion chamber of peviform, the combustion chamber has formed suitable containing to the pot body, and form an airtight combustion space, be mixed into the combustible gas of oxygen enrichment state after the sparking knob is lighted in air in the mixed air vessel, by the ejection of spray combustion plate, the quirk internal combustion that between the muscle of pot body and combustion chamber inner surface, forms, heating kettle body.Like this, the heat that fuel gas buring produced scatters and disappears seldom, and the thermal efficiency improves greatly.

The purpose of this utility model can also further be reached by following technical measures: the muscle of described combustion chamber inner surface shape in the shape of a spiral distributes.Like this, the quirk that forms between the muscle of pot body and combustion chamber inner surface is shape distribution in the shape of a spiral also, has increased the holdup time of flame under the pot body, makes that the heat absorption of pot body is more abundant, thorough, and the thermal efficiency has further improved.

Of the present utility model more further technical measures be: in the housing middle part have one with edge, upper end, combustion chamber in the preheating chamber that interlinks of exhaust smoke hole, its top has smoke exhaust pipe, air hose passes through from preheating chamber.Cigarette in the combustion chamber compiles this exhaust smoke hole, and is discharged by the smoke exhaust pipe on preheating chamber top from the exhaust smoke hole process.Like this, the heat that burnt gas is taken away just passes to the air that enters in the mixed air vessel greatly, thereby the thermal efficiency also is able to further raising.

Owing to taked above structure, the utility model volume is little, the thermal efficiency is high
