Abstract

The utility model relates to a novel energy-saving gas range whose fire jetting head is lower than a range face greatly. A horn-shaped heat collecting ring with a large upper part and a small lower part is installed on the periphery of the fire jetting head, a pot supporting frame corresponding to the heat collecting ring is installed on the heat collecting ring (or the heat collecting ring and the pot supporting frame are connected into integration), and then, other parts of an existing range are utilized to form the integration of the novel energy-saving gas range. The heat efficiency of the utility model can reach as high as 70%, other indexes come up to the standards, and the air preventing ability is strong. The utility model is an ideal product to replace existing gas ranges.

Description

The novel energy-conserving gas-cooker

The utility model relates to a kind of gas stove.

Existing gas-cooker, its firn-jet head all opens wide, during work flame to around radiations heat energy, cause thermal loss big, the thermal efficiency is not high.For energy savings, save coal gas, improve the thermal efficiency of kitchen range, people have carried out many improvement to gas kitchen ranges.Such as, various novel burning shower nozzles, magnetizing assembly, infrared facility etc. have all been obtained certain effect.Patents 882071483,902151215 etc. design a kind of gas kitchen heat-flash dish or flame-gathering cover, load onto a firestopping ring around the kitchen range, form greenhouse effects, to energy-conservation and windproofly played certain effect.But have 1, energy-saving effect is not remarkable; 2, to the bad adaptability of various cookers; 3, do not observe flame after adding firestopping ring; 4, diminish number of drawbacks such as attractive in appearance.Patent 92212065X, 922351104 etc. has designed a kind of energy saver that is applicable to various kitchen range, its energy-saving effect is better, but exist equally attractive in appearance wait not enough, and when being made into gas-cooker by it, its energy-saving appliance part exceeds standard because of temperature is high, can not make whole kitchen range.

The purpose of this utility model be development and design a kind of not only had energy-efficient, but also the novel gas kitchen range of wind-shielding function is arranged.

The scheme that the utility model adopts

Flame kitchen range (1) is starkly lower than the last plane (2) of gas-cooker, the peripheral heat absorbing ring (3) of installing of firn-jet head, the pot supporter (4) that crooked radian adapts with it is installed on the heat absorbing ring (3), pot supporter (4) by with gas-cooker on the vertical component (4A) of the contacted pot supporter in plane (2) (4) and pot supporter fin part (4B) constitute.Other parts and existing kitchen range are same or similar.

Energy-saving principle: heat absorbing ring of the peripheral installation of firn-jet head has prevented the convection current and the outside radiation of heat of cold air effectively.Simultaneously, utilize the size of a pot fin part of pot supporter, clearance distance between control cooker and the heat absorbing ring heating surface, secondary wind reasonably is provided, reduces excess air, thereby improved flame temperature significantly, accelerated the burning velocity of fuel, feasible burning is more abundant, has improved the thermal efficiency of kitchen range significantly, has reached purpose of energy saving.

Concrete structure of the present utility model is provided by the following description and accompanying drawing thereof:

Fig. 1. front view of the present utility model

Fig. 2. vertical view of the present utility model

Fig. 3. the cutaway view Amplified image of Fig. 1

As shown in the figure, the firn-jet head of this efficiency energy saving gas range (1) is lower than kitchen range face (2) significantly, and a heat absorbing ring (3) is installed in the periphery of firn-jet head (1); The heating surface of heat absorbing ring (3) is that infrared radiation coating or reflecting coating are coated on the sheet metal, is the insulation material (5) with the binding agent bonding below the sheet metal.Pot supporter (4) is installed on the heat absorbing ring (3), and a pot fin part (4B) of pot supporter adapts with the crooked radian of heat absorbing ring (3).The height of a pot fin part (4B) of pot supporter is being controlled the clearance distance between cooker and the heat absorbing ring heating surface, the closer to firn-jet head, and its distance big more (about 8-15mm); Far away more from firn-jet head, its distance more little (about 4-9mm).Kitchen range other parts and existing kitchen range are same or similar.

Gas-cooker according to the utility model made has: 1, thermal efficiency height, after tested its The thermal efficiency reaches more than 70%, compares solar term with general gas kitchen range (thermal efficiency 55%) and reaches 30 %; 2, all other indexs can be up to standard; 3, capability of anti-wind is strong, is household gas utensils The ideal product that updates.
