Abstract

The utility model relates to a combustion gas heating arrangement which comprises a combustion gas valve, and a casing without a top cap of which the horizontal section is of a long strip shape, wherein the upper portion of the casing is movable provided with a perforated plate made by the fireproof material which is fit with the shape of the end surface of the upper portion of the casing and is provided with through holes which penetrate the upper surface and the lower surface. The lower part of the inner portion of the casing is provided with a T-shaped mixing air pipe of which the left air outlet and the right air outlet are left-right symmetrical arranged. The air inlet of the mixing air pipe is positioned at the outer portion of the side upright wall of one side of the casing, and the combustion gas valve is fixed on the axial line of the end surface of the air inlet via a bracket. The horizontal section of the casing of the utility model and the shape of the perforated plate used as the combustion surface are all of the long strip shape, thereby under the precondition of ensuring the combustion heating area without increasing the size of the oven body or the roaster body, the requirement that the utility model is arranged under the side lower portion of the being baked food is satisfied, thereby the aim of baking food without oil smoke is achieved.

Description

Gas-operated thermal bath facility

Technical field: the utility model relates to a kind of heater, is meant a kind of gas-operated thermal bath facility especially.

Background technology: at present, people are burning, are baking staple and non-staple food, during as kebob or roast duck, the gas-operated thermal bath facility that uses all is to manufacture and design according to the requirement that is arranged on by under the Broiled Dish, its shortcoming is that oil, blood, juice, bits and the condiment etc. of the material outflow that quilt is roasted in the process of barbecue can directly drop on the gas-operated thermal bath facility, thereby produce a large amount of flue gases, cause the pollution of environment.

The utility model content: the purpose of this utility model provides a kind ofly can not produce flue gas in the barbecue process, according to being arranged on by the gas-operated thermal bath facility of the requirement of Broiled Dish side-lower design.

The purpose of this utility model is achieved in that a kind of gas-operated thermal bath facility, comprise burnt gas valve, it also includes the elongated housing in half-headed horizontal cross-section, is provided with an orifice plate made from refractory material that is evenly equipped with the small through hole that connects its upper and lower surface that matches with housing upper end shape in the top movable of housing; Be provided with a T-shaped mixture pipe below the inside of housing, the left gas outlet and the right gas outlet of mixture pipe are symmetrical set; The air inlet of mixture pipe is positioned at the outside of the edge-on wall of housing one side, and burnt gas valve is fixed on the end face axis of air inlet by support.

Because the shape of the horizontal cross-section of the utility model middle shell and the orifice plate that uses as combustion front is all elongated, so its can guarantee the burning heating surface (area) (HS and increase the baking box casing within bounds or the prerequisite of baking oven body of heater size under, satisfy the utility model is placed on by the requirement of the side-lower of food roasting, can food roasting thereby both reach, can avoid producing the purpose of oil smoke gas again.

The specific embodiment: the utility model will be further described below in conjunction with accompanying drawing, a kind of gas-operated thermal bath facility, comprise burnt gas valve 2, it also includes the elongated housing in half-headed horizontal cross-section 4, is provided with an orifice plate 5 made from refractory material that is evenly equipped with the small through hole that connects its upper and lower surface that matches with housing 4 upper end shapes in the top movable of housing 4; Orifice plate 5 meanwhile, can also produce infra-red radiation for the air mixture of its inner small through hole of flowing through provides a combustion front after orifice plate 5 is heated; Below the inside of housing 4, be provided with a T-shaped mixture pipe 6, the left gas outlet 7 and the right gas outlet 8 of mixture pipe 6 are symmetrical set, and left gas outlet 7 and right gas outlet 8 can guarantee air mixture is distributed within the elongated mixed air vessel that is surrounded by housing 4 and orifice plate 5 more equably; The air inlet 1 of mixture pipe 6 is positioned at the outside of the edge-on wall of housing 4 one sides, and burnt gas valve 2 is fixed on by support 3 on the end face axis of air inlet 1, and the outlet of burnt gas valve 2 is over against air inlet 1, and the inlet of burnt gas valve 2 is connected with gas supply pipe; During use, open burnt gas valve 2, the malleation combustion gas will enter mixture pipe 6 by air inlet 1, and air also can be introduced among the mixture pipe 6 and combustion gas mixing by the space on the air inlet 1, the air mixture that generates housing 4 inside of flowing through are flowed out the back at last and are lighted the small through hole from orifice plate 5.

In order to reduce the eddy current that air mixture and housing 4 inwalls produce because of gas shock, guarantee the uniform and stable of air mixture, the setting that can be inclined upwardly of the end face of left gas outlet 7 and right gas outlet 8.

Because by support 3 burnt gas valve 2 is installed on the air inlet 1, in order to guarantee that enough air can flow into mixture pipe 6 among the slit that forms between air inlet 1 upper bracket 3 and the burnt gas valve 2, mixture pipe 6 is positioned at the axial cross section shape of the tube chamber of air inlet 1 one ends can do flue, to enlarge the diameter of air inlet 1.

The duration and degree of heating that the utility model also can directly be used as gas furnace uses.
