Abstract
The utility model provides a combustion chamber of gas kitchen ranges, comprising an ejection mixing tube and a nozzle. The nozzle is arranged at the lower part of the ejection mixing tube; the inner perisporium of the ejection mixing tube is a multi-stage stepped appearance. The diameter of the inner perisporium at the subordinate step is smaller than the diameter of the inner perisporium at the superior step, and the side wall of all levers of the steps are arranged with several air mixing holes. The range core make the gas fully mixed with the air; the combustion is enough; the energy can be saved more than half gas compared with the original range. The ejection mixing tube is integrated the nozzle into one unit, and the problems of the sealing and safe caused by matching loose between the mixing tube and the nozzle can not be occurred.
Description
Technical field
The utility model relates to the stove or the kitchen range of using gases fuel, specifically is meant a kind ofly to realize energy-conservation stove core of combustion-gas range by architecture advances.
Background technology
Combustion chamber is the gas-cooker vitals, can its structure fully burn to fuel gas and play a key effect, its structure connects a nozzle usually and constitutes below mixing tube, mixing tube sidewall differing heights is provided with a plurality of air mix aperture, nozzle links to each other with source of the gas, and fuel gas enters mixing tube from nozzle, and air enters mixing tube from mix aperture to be mixed with fuel gas, gaseous mixture enters the flue internal combustion from the mixing tube upper end, and stone or metal plate for standing a stove on as a precaution against fire is heated.
Chinese patent has been announced a kind of " putting fire gas combustion range automatically for quiver " for No. 00220166.6, its combustion chamber is made up of constraint mixing drum, injection mixing tube and nozzle, the constraint mixing tube is a cavity body, be equivalent to flue, its top links to each other with the stone or metal plate for standing a stove on as a precaution against fire bottom surface, the injection mixing tube is the step pipe, comprise the elongated tubular on top and the short and thick pipe of bottom, elongated tubular is positioned at the constraint mixing drum, short and thick pipe is positioned at below, constraint mixing drum bottom surface, short and thick pipe perisporium and elongated tubular bottom perisporium are provided with a plurality of mix aperture in differing heights, and nozzle and short and thick pipe bottom are fixed by threaded engagement.
Aforementioned combustion chamber has following shortcoming: one, though the injection mixing tube is the step pipe that comprises the short and thick pipe of top elongated pipe and bottom, though the tube wall of injection mixing tube is provided with the mix aperture of differing heights, but its inboard tube wall is a smooth cylinder, the air that never level mix aperture is come in can not fully mix with the fuel gas through the injection mixing tube, thereby can not fully burn; Two, adopt threaded engagement between nozzle and the injection mixing tube, loosening easily, poor sealing, and cost height, security is bad.
The utility model content
The utility model provides a kind of stove core of combustion-gas range, and its main purpose is to overcome existing stove core of combustion-gas range can not make combustion gas and air fully mix, thereby the shortcoming that can not fully burn, waste energy.
The nozzle that another purpose of the present utility model is to overcome existing stove core of combustion-gas range is for independent detachable, and is loosening easily, the shortcoming that sealing and security are bad.
The utility model adopts following technical scheme: a kind of stove core of combustion-gas range, comprise injection mixing tube and nozzle, nozzle is connected in injection mixing tube below, the internal perisporium of injection mixing tube is for being multistage stepped, the diameter of subordinate's ladder internal perisporium is less than the diameter of higher level's ladder internal perisporium, and the sidewall of ladders at different levels is arranged with some air mix aperture.Combustion gas enters the injection mixing tube by nozzle, makes progress along its stair-stepping internal perisporium, and mixes with air step by step by the air mix aperture of ladders at different levels, strengthens the air capacity of sneaking into step by step, reaches mixed uniformly purpose.
Described injection mixing tube and nozzle are one-body molded, do not have the problem of matching loose between injection mixing tube and the nozzle.
Described injection mixing tube upper periphery face is provided with the external screw thread that can match with gas-cooker flue bottom, and the nozzle outer peripheral face is provided with the external screw thread that can match with the air supply pipe of source of the gas.
Described nozzle top sidewall also is provided with the air mix aperture.
The periphery wall of described injection mixing tube is a multi-prismatic surface, and described air mix aperture is distributed on this multi-prismatic surface.
By above-mentioned description to the utility model structure as can be known, compare, the utlity model has following advantage with prior art: one, combustion gas can fully mix with air, sufficient combustion, energy savings greatly, comparable original gas-cooker is saved combustion gas over half; Two, injection mixing tube and nozzle are one-body molded, do not have the sealing brought because of matching loose and the problem of security aspect between injection mixing tube and the nozzle.

The specific embodiment
Say a specific embodiment of the present utility model in detail referring to figs. 1 through Fig. 7.
Extremely shown in Figure 6 as Fig. 1, this stove core of combustion-gas range comprises injection mixing tube 1 and nozzle 2, injection mixing tube 1 and nozzle 2 integrally casting moulding, the internal perisporium of injection mixing tube 1 is stepped, comprise four cascaded surfaces 11,12,13,14 from the bottom to top, the internal diameter of each cascaded surface 11,12,13,14 increases from the bottom to top successively, and the sidewall of ladders at different levels is arranged with some air mix aperture 10.
Injection mixing tube 1 periphery wall is one or six prismatic surfaces, the bottom of cascaded surface 11 extends into the napex of nozzle 3, the top of this nozzle 3 is provided with three main air mix aperture 30 that equidistantly distribute, cascaded surface 12 sidewalls are evenly distributed six secondary air mix aperture 101, and corresponding respectively being distributed on six faces of six prismatic surfaces, cascaded surface 13 sidewalls are also evenly distributed six three grades of air mix aperture 102, also corresponding respectively being distributed on six faces of six prismatic surfaces, cascaded surface 14 sidewalls are evenly distributed three level Four air mix aperture 103, and corresponding respectively be distributed in six prismatic surfaces apart from one another by three faces on.
