Abstract

The utility model discloses an energy-saving device for a gas stove. The utility model is composed of a ring form base and a cylinder assembly, and the cylinder assembly is concentrically arranged on the base and is made of the thermal insulation heat resisting material. The inner wall of each cylinder is coated with far infrared coating. When the device and the gas stove are matched together to be used, the contact face of the flame and a kettle can be enlarged, and one part of dispersed heat energy can be reused due to the radiation of the infrared coating. In addition, the influence of the wind to the flame can be avoided, and therefore, the defect that the conventional furnace has the disadvantage of low heat efficiency is overcome. When the gas stove which is provided with the utility model is compared with the same gas stove, the heat efficiency is raised by 40% to 50%, the energy consumption and the cost are reduced by 35% to 45%, and the heating time is reduced by 10% to 30%.

Description

Energy-saving device for gas stove

The utility model belongs to a kind of and the matching used energy saver of house gas boiler, both can be used for using the gas furnace of natural gas, coal gas, biogas, gaseous mixture, also can be used for coke and honeycomb briquette stove, uses but be particularly suitable for gas furnace.

The structure of present all kinds of domestic gas stoves generally is worn-out open type, be that duration and degree of heating is positioned at the stone or metal plate for standing a stove on as a precaution against fire middle part, several feets are located on the stone or metal plate for standing a stove on as a precaution against fire, duration and degree of heating and support all are exposed to upper of furnace body with top, therefore, in use directly contact the bottom of a pan partly is utilized except that flame, all the other more most heat energy have then lost around gas furnace; If met wind, that I guess gentle breeze all will make flame depart from the bottom of a pan, cause bigger heat loss, this to barrel-shaped pot more so.Therefore, it is lower that this class gas furnace exists the thermal efficiency, only is about 30～35% generally, both wasted fuel, expend time in again, and when wind is arranged the bottom of a pan disadvantage such as inhomogeneous of being heated.

The purpose of this utility model is the matching used energy saver of a kind of and conventional gas furnace of design, this energy saver both can be with flame control within the specific limits, again can with its to around the heat energy that distributes return part utilization, thereby reach the thermal efficiency that improves gas furnace, fuel saving, expense and purpose such as between the time.

1 ring bodies of employing of the present utility model is as base, the assembly that one or more concentric drums that play heat shield effect constitute is set on this base, each cylinder adopts heat-resisting heat-barrier material to make, and each cylinder inner wall all applies the far infrared coating, and this device is by base or set up in the support plate of base bottom and connect with the combustion gas stone or metal plate for standing a stove on as a precaution against fire and be used with gas furnace.Above-mentioned each concentric drums both can be designed to contour, low, outer high stairstepping or tilted mouth shape in also can being designed to, cylinder heights is generally 40～140mm, and the internal diameter of each cylinder is fixed by the specification of general bucket pot commonly used and frying pan, but the difference of the external diameter of each inner diameter and corresponding bucket pot must not be less than 10mm; The number of cylinder can be selected according to operating position, generally then can be provided with 1～4.The material of cylinder can adopt alumina silicate or other heat-resisting, heat-barrier material manufacturing.

The utility model is owing to adopt the cylinder heat-resisting, that heat-barrier material is made as the shading ring around the gas furnace flame, and each cylinder inner wall all is coated with the far infrared coating, therefore in use this device both can increase flame and the bottom of a pan and the outside contact-making surface and with a part to around the heat energy that distributes pass through the radiation Returning utilization of infrared coating, but also can prevent to depart from the disadvantage that thermal waste is caused in the bottom of a pan etc. because of wind makes flame.Compare test with same gas furnace after using the utility model, for different pot types, the former gas furnace of its thermal efficiency ratio improves 40～50%, and actual solar term and expense 35～45% thereof save time 10～30%.Therefore, the utlity model has with the supporting use of gas furnace greatly the spoke degree improve characteristics such as its thermal efficiency, energy savings and expense thereof, saving service time.

Accompanying drawing and description of drawings

Fig. 1 is present embodiment structure and user mode schematic diagram: double dot dash line is a bucket pot body profile schematic diagram among the figure.

Among the figure: 1, gas furnace, 2, the base support plate, 3, base, 4, the concentric drums assembly, 5, the far infrared coating, 6, the frying pan feet.

Embodiment

Present embodiment is that the family expenses frying pan that φ 22～32cm bucket pot and bore generally are not more than φ 47cm is an example to be used for diameter:

This device adopts three not contour concentric drums movable sets to form on base 3, one support plate 2 is set under the base, the cylindrical shell material adopts alumina silicate tubing, thickness of pipe wall is 1.75cm, and wherein the inner core internal diameter is φ 255mm, and middle tube internal diameter is φ 295mm, the urceolus internal diameter is φ 335mm, each cylindrical shell height is respectively 60mm, and each nozzle of 90mm and 120mm is all established three frying pan feets 6, about each tube inner surface coating far infrared coating 0.15mm is thick; Base support plate 2 adopts the 5mm steel plate to be welded, base 3 also adopts alumina silicate compression moulding, " protruding " shape is adopted in present embodiment base longitudinal section, so that each cylindrical shell is located automatically, base inner and outer rings pedestal is gone into corresponding inside and outside tube, middle base is gone into middle cylinder body, and pedestal itself then is anchored on the base support plate 2 by screw.During use, will be with the support plate 2 of base 3 to be fixed on the gas furnace stone or metal plate for standing a stove on as a precaution against fire, and then interior, the domestic and abroad cylinder base in the cylinder group be encircled on the platforms accordingly in base 3, because base is " protruding " shape, so cylinder is tightened automatically.In the use,, frying pan directly can be placed on the nozzle to use when bore is when being not more than the frying pan of φ 47cm; When using the bucket pot to hot plate; If bucket pot diameter can be directly during less than φ 24cm on the feet of gas furnace, shown in double dot dash line among the figure; If when bucket pot bore is φ 26～28cm, middle tube and urceolus are only stayed in the inner core taking-up; When bucket pot bore is φ 30～32cm, then middle tube is also taken out and only stay urceolus and equally use as described above, can be when being used for the bucket pot in a word according to the diameter configuration or the increase and decrease cylindrical shell of bucket pot, so that reach optimum efficiency.
