Abstract

The utility model discloses a domestic range, particularly an accessory used for ranges. The utility model comprises an inner sleeve, an outer sleeve and a heat insulating layer. The utility model is characterized in that the outer wall of a reverse truncated cone-shaped inner sleeve is coated with a heat insulating layer, an upper end outer edge flange of the reverse truncated cone-shaped inner sleeve is arranged on the upper end of the outer sleeve, small through holes which are uniformly distributed are arranged in a composite body composed of the inner sleeve and the heat insulating layer, and the inner wall of the inner sleeve is provided with three uniformly distributed pot supporting frames of which the upper ends are fixed to the outer edge flange. The utility model has the advantages that the gas can be thoroughly burnt and the heat quantity sent by the flame can be maximally recovered and utilized. Compared with the old type gas range, the utility model can save the energy by 35 to 56%. The domestic range is sanitary and beautiful.

Description

The gas cooker energy saving device

The utility model relates to a kind of home furnace, especially for the annex of cooking stove.

At present relevant with gas-cooker energy-saving scheme is a lot, and patent relatively early has＜the gas disk energy-saving water heater〉(patent No. 90217503.3), many after this people improve this again in succession.As on January 26th, 1994 utility model patent communique disclosed a kind of＜the gas-cooker efficient energy-saving device (patent No. 93236783.6) its primary structure is: inwall is made by pottery, which is provided with the spill ring body of arc muscle, and the shell periphery is established heat-insulation layer.Its weak point is that heat-insulation layer is too far away from heating surface, can not guarantee effectively that the heat that flame sends does not does not scatter and disappear, and the spill ring body is provided with air admission hole simultaneously, can not replenish enough oxygen to flame it is fully burnt.

The purpose of this utility model is to provide a kind of and combustion gas is fully burnt and maximally utilises the gas cooker energy saving device of the heat that flame sends.

The purpose of this utility model can realize by following measure: a kind of gas cooker energy saving device, it includes interior cover, overcoat and heat-insulation layer, it is characterized in that: upper end extension flange places the interior cover of truncated cone shape of outer set upper side, its outer wall covers heat-insulation layer, on the complex of interior cover and heat-insulation layer composition, be provided with uniform small through hole, be fixed on three uniform pot supporters on its extension flange on the inwall of interior cover is provided with.Overcoat is a cylindrical shell, and its underpart is evenly equipped with 3～8 wind holes.

The utility model mainly includes overcoat, heat-insulation layer, interior cover and pot supporter.Wherein the structure of overcoat and shape are not all limit, and no matter are that support or its upper end of cartridge type housing are annulus.Preferably overcoat is a cylindrical shell, and its underpart is evenly equipped with 3～8 through holes, i.e. combustion air hole, and it can be flame combustion-supporting oxygen is provided.Be preferably in the overcoat lower end and establish 3～4 square fixed heads.Be fixed on by screw on the plane of gas-cooker.The interior cover of set upper side outside the flange of extension places on being provided with in overcoat.Should be metal truncated cone shape housing by interior cover, the big opening in its upper end is corresponding with the bottom of a pan, the little opening of lower end is corresponding with the flame emission place of gas-cooker, it can be crowded around flame at the bottom of the cooking device, the heat of flame is not is not scattered and disappeared, inner metal sleeve can also be accumulated heat and constantly with the radiation at the bottom of cooking device of these heats, add thermal effect with enhancing simultaneously.Heat energy radiation at the bottom of cooking device fully for cover in making covers heat-insulation layer at outer wall of inside race.Preferably heat-insulation layer adopts composition silicate coating, and it is not only high temperature resistant but also good heat-insulation effect.Be provided with several uniform small through hole in addition on the complex of being made up of interior cover and heat-insulation layer, it also is the combustion air hole.Air from overcoat enters flame zone via above-mentioned wind hole, can impel the carbide in the combustion gas fully to burn, the pollution that removes smoke first, the caloric value when also increasing fuel gas buring simultaneously.Be provided with three uniform pot supporters on interior cover inwall, it is the N font, overlaps on the flange of extension in the upper end places, and is fixed by securing member.The pot supporter lower end is a free end, and they are all towards the center.This pot supporter can make cooking device and interior inner room have certain slit, so that make fluids such as flame unimpeded.

The utility model has following advantage compared to existing technology:

1, combustion gas is fully burnt.

2, the heat that flame can be sent is recycled to greatest extent to compare with old-fashioned gas-cooker and can be saved 35～56% the energy.

3, health, attractive in appearance.

Drawing is described as follows:

Fig. 1 is that master of the present utility model looks generalized section.

Fig. 2 is a schematic top plan view of the present utility model.

The utility model is described in further detail to utilize the example shown in the accompanying drawing.In the schematic diagram of gas cooker energy saving device illustrated in figures 1 and 2, overcoat 1 is a cylindrical metal case, and its underpart is evenly equipped with 4 through holes 2.The square fixed head 3 of 4 band screws is established in the overcoat lower end.The interior cover 4 of set upper side outside the flange of extension places on being provided with in overcoat, cover is stainless steel truncated cone shape housing in this.Cover composition silicate coating heat-insulation layer 5 at outer wall of inside race.On the complex of forming by interior cover and heat-insulation layer, be provided with 19 uniform small through hole 6.Be provided with three uniform pot supporters 7 at interior cover inwall, overlap on the flange of extension in its upper end places, and fixed by securing member, the pot supporter lower end is all towards the center.
