Abstract

The utility model relates to a gas energy-saving device which is manufactured by special fireproof thermal-insulating materials in the burning way. The utility model comprises a flame returning ring, a reversing chamber, a smoke exhausting hole, and a pot-bottom-shaped structure of a combustion-supporting hot air flowing hole. The inner and the outer surfaces of the gas energy-saving device are coated with high-efficiency heat-insulating fire-resistant thermal-insulating paint, and the outer surface of the upper part is covered with a circle of decorative iron sheets. The utility model which has special structure and artful design can effectively prevent the dissipation of heat, and the energy-saving effect is obvious.

Description

The fuel gas energy-saving device

The utility model belongs to the household gas apparatus parts, is a kind of gaseous fuel energy-saving appliance.

In recent years, gaseous fuel entered China town dweller's kitchen in a large number, and various gaseous fuels such as coal gas, liquefied gas, natural gas, biogas are easy to use easily, and are fast clean, are subjected to liking of numerous residents deeply.Along with China's rapid economic development, people's rhythm of life is accelerated, and in order to alleviate the environmental issue that is on the rise, the town dweller of using gases fuel will be multiplied.But all gas-cookers that use exist a common problem at present, promptly all are full open form burning gases, cause a large amount of of heat to scatter and disappear.According to test, during various gas-cooker burning gases fuel, the heat up to 30-40% is scattered and disappeared.Though gas-cooker hot water block energy-saving appliance is arranged on the market, because of the heat radiation utilization rate is low, energy-saving effect is undesirable, adds to use inconvenience, and people seldom use.Other is not reported at home about the technology that overcomes the problems referred to above and uses.Along with gaseous fuel user's increase, and the anxiety of gas energy, it is more outstanding, more serious that this problem will seem.

The purpose of this utility model provides the gaseous fuel energy-saving appliance that the special refractory heat-insulating insulation material of a kind of usefulness is made, its structure uniqueness, directly be placed on the household gas range and get final product, energy-saving effect is remarkable, can make the various gas-cookers that generally use at present save gaseous fuel about 30% under the identical condition.

The purpose of this utility model is achieved in that with special refractory heat-insulating insulation material makes a closed pan bottom shape structural solid, replaces the pot frame on the household gas range, uses on various kitchenwares (as pot, kettle etc.) place.Its inwall has four layers of ladder, and the orlop ladder is the combustion chamber, has many combustion-supporting thermal air current through holes on the wall and tiltedly is in communication with the outside to energy-saving appliance outer wall below, about the about 3mm in aperture.Gaseous fuel is in the combustion chamber internal combustion, the burned indoor negative pressure of cool ambient air sucks the opening that burns heat and becomes hot-air to enter the combustion chamber combustion-supporting, and the burned chamber interior walls of clean-burning flame is heat insulation, remain in a standstill, enter second layer ladder (second layer reversing chamber) after giving the bottom of a pan when reflection and folding.Flame enters the 3rd layer of ladder (the 3rd layer of reversing chamber) after the petal-shaped inwall of second reversing chamber is given the bottom of a pan by heat insulation, viscous flow for the second time, tempering, reflection and refraction, flame is heat insulation by petal-like inwall again, viscous flow, tempering, reflection and refraction enter the 4th layer of (top layer) ladder, promptly upper end and pot form the 4th a layer of reversing chamber of closed, and flame all refluxed, heat insulation, reflection and refraction enter the external world by the many fume emissions hole that is in communication with the outside after giving the bottom of a pan.Aperture, fume emission hole is about 8mm.Like this, gaseous fuel is after the utility model burning, and through four tempering, viscous flow, heat insulation, reflection and refraction, most heats are absorbed by the bottom of a pan, have extremely effectively prevented scattering and disappearing of heat.Simultaneously, the utility model is provided with combustion-supporting hot air generator, makes gas fuel combustion more complete, more thorough, thereby has further saved gaseous fuel.And the fume emission hole be provided with solved because of hingle by the roasting problem that can't take with hand of scalding.Through the use test more than 2 years, COMPREHENSIVE CALCULATING on average can be saved gaseous fuel 30%.

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a vertical view of the present utility model.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure (1). the 4th layer (level) totally-enclosed time flame circle (wall); (2). energy-saving appliance fume emission hole; (3). the 3rd layer (level) returns flame circle (wall); (4). the 3rd layer of (level) reversing chamber; (5). the second layer (level) returns flame circle (wall); (6). the second layer (level) reversing chamber; (7). ground floor (level) returns flame circle (wall); (8). the combustion-supporting thermal air current through hole of energy-saving appliance; (9) energy-saving appliance mounting yoke; (10). effectively insulating thermal insulation fire-resistant coating; (11). decorate the iron sheet cover.

In Fig. 1 (or Fig. 2), gaseous fuel returns at ground floor that end spaces is a combustion chambers burn under the flame circle (wall) (7), cool ambient air enters the combustion chamber through combustion-supporting thermal air current through hole (8) makes burning more abundant, more thorough, combustion flame kept off back by the bottom of a pan after ground floor to return flame circle (wall) (7) heat insulation, remain in a standstill, after giving the bottom of a pan, reflection and refraction enter second layer reversing chamber (6), once more heat is passed to the bottom of a pan, to return flame circle (wall) (5) through the petal-like second layer heat insulation for flame then, remain in a standstill, reflection and refraction are conducted heat again to the bottom of a pan to entering the 3rd layer of reversing chamber (4) behind the bottom of a pan, the flame upper reaches is heat insulation by petal-like the 3rd layer time flame circle (wall) (3) again, remain in a standstill, reflection and refraction are passed to a pot thing with heat and are entered the 4th layer of reversing chamber, and flame is all kept off back by the 4th layer of totally-enclosed time flame circle (wall) (1) and enters the external world by fume emission hole (2) after heat passed to the bottom of a pan.

Energy-saving appliance mounting yoke (9) is the pot frame (dish) on the gas-cooker and place mounting yoke on the gas-cooker before the utility model replaces.
