Abstract

The utility model relates to a gas burning infrared ray range. The utility model is composed of a gas inlet pipe, a gas control switch, a gas inlet nozzle, a flow chamber, an infrared fire tray and a gas mixing cavity body which is formed between an infrared ray fire tray and a circular casing. A primary gas mixing chamber and a secondary high-temperature gas mixing chamber are arranged in the cavity body; gas stream can be disturbed by an air exchange plate which is positioned between a groove channel and the two mixing chamber, so air and air can be mixed fully and flow synchronously; the mixed gas has an optimize concentration, which is favorable for gas to burn fully. Having the advantages of complete combustion, material saving, safety, less pollution and few pollution, the utility model can improve caloricity.

Description

Energy-saving gas burning infrared ray range

The utility model belongs to the improvement to existing gas kitchen ranges, is mainly used in the infrared kitchen range of combustion gas.

Along with development of technology, the kitchen range of using in people's daily life are also constantly improving, the gas kitchen ranges kind of Xiao Shouing is more in the market, on structural design, use on the material, control on the gas flow all than bigger improvement was arranged in the past with automatic on the sparking mode, but with regard to the kitchen range that at present wide model is used, also do inadequately aspect the burning condition improving, combustion-supporting air is not taked the preheating measure, ignition temperature is lower, and needed oxygen mainly obtains from ambient air by diffusion during burning, because the lack of air incomplete combustion, flame is yellow, the thermal efficiency is lower, waste fuel, contaminated environment.

The purpose of this utility model is a kind of economical gas infrared kitchen range that burns complete, safe and reliable, that contaminative is little of design.

The energy-saving infrared kitchen range of the utility model is by admission line, compositions such as kitchen range pin on burner, circular shell and the housing and pot frame.Burner comprises gas control switch, nozzle of air supply, the gaseous mixture cavity that infrared ray tray for combustion and infrared ray tray for combustion and circular shell constitute, be characterized in along two annular preheating chamber are arranged in the circular shell top edge, and on top the trailing flank of edge is provided with air inlet, cold air divides mobile limit, two roadsides pre-heating temperature elevation through air inlet, and it is indoor to enter band stream through hot-air channel.

Place, preheating chamber gas outlet in the gaseous mixture cavity is provided with hot-air channel, below the infrared ray tray for combustion, is provided with gas mixer chamber and secondary high-temperature gas mixing chamber.The bottom of a gas mixer chamber is exactly a circular shell, a gas mixer chamber is a round entrance, bearing of trend in its bottom along inlet, being provided with sectional area is the semicircular power of disappearing groove, this groove extends internally always, its end points reaches the middle part of a gas mixer chamber, is provided with secondary high-temperature gas mixing chamber above the gas mixer chamber at one time, and in the centre of first and second mixing chamber the air dividing plate for the power mixing usefulness that disappears is housed.The air dividing plate width can be 10--20mm.

The infrared ray tray for combustion is a porous disc, is the inside that is contained in the circular shell top edge, and this dish is gone up the plane than the low 15--25mm of circular shell top edge, makes preheating chamber on tray for combustion.Flame is in the internal-combustion of circular shell top edge, and its thermal loss is little, and waste heat on every side carries out preheating to the air in the preheating chamber, and the flame at middle part can improve the thermal efficiency of cookers such as pot, spoon.

The air admission hole of band stream chamber and nozzle are for being threaded, and rotary nozzle can be adjusted the air gap of advancing between air admission hole and the nozzle, and the combustion efficiency of acquisition the best.

The side of band stream chamber 18 shells below hot-air channel, have one and transfer the wind valve, mainly be when using LPG gasifying, should will transfer the wind valve to open, and between the air admission hole of nozzle and band stream chamber, add a tube connector, and on the tube wall of the afterbody of tube connector, have the pore of two symmetries.

When using town gas, use the gas appliance nozzle instead, and will transfer the wind valve to close, can reach best ignition temperature.

Open switch when using kitchen range, combustion gas enters in the mixing chamber cavity from nozzle, because the band stream effect of combustion gas, cold air from air inlet through preheating chamber, flow the chamber from the preheating chamber gas outlet through hot-air channel and band again, porch and combustion gas at a gas mixer chamber are met, hot-air flows down at the band of combustion gas, together enter gas mixer chamber one time, and flow along the groove on the bottom surface near the gas of bottom, when reaching the terminal point of groove, airflow obstruction is because air-flow is subjected to disturbance, combustion gas can be mixed preferably with hot-air, air-flow enters the further high temperature of secondary mixing chamber through air dividing plate to be mixed, and when reaching near ignition temperature and concentration, can enter the burning of infrared ray tray for combustion.

The utility model and existing gas-fired infrared kitchen range relatively have following advantage:

1, adopted air preheating chamber, made full use of waste heat and improved ignition temperature, favourable burning.

2, owing to adopted combustion gas band stream hot-air to carry out combustion-supporting mode, can adjust hot-air and the flammable mixing ratio of combustion gas automatically, enter the gap of air between adjustable band stream chamber air admission hole and the nozzle and transfer the wind valve.Make the combustion air abundance, two kinds of gas through once, the secondary mixing chamber mixes, and particularly adopted groove and air dividing plate rough air structure, two kinds of gases are mixed, can be adjusted to the concentration of catching fire preferably, can completing combustion, improve calorific value, fuel saving has reduced pollution.

3, these kitchen range flameholding, by regulating the controlled preparing high-temp fire of flame, in wet fire, the fiery ignition temperature of idle temperature.
