Abstract

The utility model relates to a household gas range composed of a range body, and an ejector, a stove plate, a metal net radiator, etc. which are arranged on the range body. A metal supporting net, a flat pattern Fe-Cr-Al metallic inner net, and a flat pattern Fe-Cr-Al metallic outer net which are stacked together in sequence between a low pressing cover and an upper pressing cover of the metal net radiator of the utility model. The utility model has the characteristics of simple structure, low cost, favorable burning effect, no back fire, etc. Besides, the processing and the installing procedures are simplified, and the household gas range is more suitable for mass production.

Description

General-purpose energy-saving infrared radiation gas-cooker

The utility model relates to a kind of household gas utensils.

I once with other people co-applications 95212090.9) and " wire netting infrared burner " (patent No. 95217730.7) " general-purpose energy-saving the infrared gas stove " (patent No.:, though this utility model has some characteristics, but on design, still exist following deficiency: 1, because the metal Intranet is the part of colding pressing, internal stress is not eliminated, and occurs " recessed " phenomenon after use a period of time easily; 2, because Intranet is matrix, and insufficient rigidity, instability, also thermal deformation is recessed easily, causes chamber temperature too high, produces tempering and " blows out " phenomenon; 3, because only adopt one deck Intranet, the aperture of Intranet is greater than the critical aperture of flame propagation, and stays spacing between the inside and outside net hardly, influences the gas-flow wire side of overflowing reposefully, very easily causes tempering " to blow out " phenomenon.In addition, this utility model also has some optional features such as fire holding cycle, wind loop, accent airduct, causes shortcomings such as complex structure, cost height.

The purpose of this utility model is intended to overcome the deficiency of prior art, and provide a kind of simple in structure, reasonable in design, result of use is good, be suitable for practical general-purpose energy-saving infrared radiation gas-cooker.

The utility model is made up of stove (12) and the injector (7), stone or metal plate for standing a stove on as a precaution against fire (5) and the wire netting radiator several parts such as (10) that are installed on the stove (12).The metal holder net (16) that stacks successively, two-layer flat pattern iron-chromium-aluminum metal Intranet (15) and iron-chromium-aluminum metal outer net (14) have been clamped between the lower cover (17) of the utility model wire netting radiator (10) and the upper press cover (13) through annealing in process.

Distance between the utility model metal Intranet (15) and the metal outer net (14) is 6 ± 1 millimeters.

The mesh of the utility model metal Intranet (15) is that 44-33 order/inch, wire diameter are the 0.213-0.35 millimeter, the mesh of metal outer net (14) is that 10-8 order/inch, wire diameter are the 0.8-1.0 millimeter, and the mesh of metal holder net (16) is that 4 order/inches, wire diameter are 2.0 millimeters.The material of metal holder net (16) is a common iron wire.

The utlity model has following advantage:

1, Intranet (15) has been eliminated internal stress after annealing in process, uses indeformablely for a long time, does not rupture;

2, Intranet (15) is designed to flat pattern, is provided with metal holder net (16) in addition in its lower section, has strengthened the rigidity of Intranet (15), and the chamber temperature of avoiding original concave shape Intranet and temperature distortion thereof to cause is too high, and phenomenon " is blown out " in the tempering that produces;

3, because Intranet (15) is that flat pattern is not recessed, and is superimposed together by two-layer Intranet and forms, prevent the generation of " tempering " phenomenon effectively;

In addition, the utility model also has characteristics such as simple in structure, that cost is low, has simplified processing, installation procedure, is more suitable for producing in batches.

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

Fig. 2 is the utility model injector, combustion chamber stove body portion structural representation;

Fig. 3 is the utility model wire netting radiators structural representation;

Among the figure: 1, intake valve; 2, pad; 3, deep bead; 4, decorative panel; 5, stone or metal plate for standing a stove on as a precaution against fire; 6, screw; 7, injector; 8, screw; 9, heat insulating mattress; 10, metallic radiator; 11, movable leg; 12, body of heater; 13, upper press cover; 14, outer net; 15, two layers of Intranet; 16, holder net; 17, lower cover.

Most preferred embodiment of the present utility model as shown in the figure, intake valve (1) is installed on the deep bead (3) on the injector (7), and pad (2) is housed therebetween.Decorative panel (4) is fixed on the stone or metal plate for standing a stove on as a precaution against fire (5) with screw (6).Injector (7) is connected with body of heater (12) by screw (8), heat insulating mattress (9).Stone or metal plate for standing a stove on as a precaution against fire (5) is an one with body of heater (12) sealing and fixing.Movable leg (11) is hinged on the stone or metal plate for standing a stove on as a precaution against fire (5).Wire netting radiator (10) is installed on the stone or metal plate for standing a stove on as a precaution against fire.Wire netting radiator of the present utility model (10) by upper and lower gland (13), (17) and the metal holder net (16) that stacks successively, two-layer be 6 ± 1 millimeters through the flat pattern iron-chromium-aluminum metal Intranet (15) of annealing in process and the distance between the metal outer net (14).The mesh of metal Intranet (15) is that 44-33 order/inch, wire diameter are the 0.213-0.35 millimeter, the mesh of metal outer net (14) is that 10-8 order/inch, wire diameter are the 0.8-1.0 millimeter, metal holder net (16) is a common iron wire, and its mesh is that 4 order/inches, wire diameter are 2.0 millimeters.

Operation principle of the present utility model is: the kinetic energy when utilizing the coal gas ejection, make fuel gas through intake valve (1), windscreen (3), suck by injector (7) the required whole air that will burn, and fuel gas and air are mixed, mixed gas enters body of heater, the mixed gas flow of being returned by the furnace body wall cavity reflection passes through the shunting of holding in the palm net (16), and with more steady even velocity effusion wire side, the mist after lighting is flameless combustion between inside and outside net.The infrared ray flame that fervid inside and outside net and the high-temperature flue gas between them promptly send extreme temperatures.
