Abstract

The utility model relates to an energy-saving hood for a gas cooker, belongs to the technical field of cooking utensils, and aims to provide the energy-saving hood for the gas cooker, which can fully utilize the heat generated fuel gas and improve heat utilization rate in the use of the cooking utensil. The utility model adopts the technical scheme that: the energy-saving hood comprises a retainer ring and a ferrule; the inner diameter of the cylindrical retainer ring is larger than that of the outer ring of the burner of the cooking utensil; the ferrule takes the shape of a circular ring; the outer peripheral rack of the ferrule is placed at the upper opening of the retainer ring, and is matched with the rim of the upper opening of the retainer ring; and a plurality of ventilation breaches are uniformly formed on the edge of the inner periphery of the ferrule. After adopting the energy-saving hood, most part of the heat generated by the fuel gas diffuses around the bottom of a pan through the ventilation breaches of the ferrule, and self-loss of heat is greatly reduced, so that greater firepower can be obtained by using less power fire and energy is saved. The energy-saving hood with the advantages of simple structure, easy manufacturing and low price has good social and economic benefits and is valuable for popularization.

Description

A kind of gas cooker energy saving cover

Technical field

The utility model relates to a kind of energy saver of gas-cooker, belongs to the kitchen range technical field.

Background technology

The family expenses kitchen range generally all are open, and promptly the heat of a duration and degree of heating part is absorbed by pot, and remainder then freely runs off.Therefore when our cooking was cooked, the heat that combustion gas produced had only sub-fraction to be utilized, and major part has but lost.And duration and degree of heating is big more, and heat runs off many more relatively, and in other words, along with the increase of duration and degree of heating, heat utilization efficiency is successively decreased.From the using energy source angle, this waste is surprising, if can improve kitchen range, reduces the loss of heat as much as possible, and for energy savings, it is very useful increasing economic efficiency.

Summary of the invention

Technical problem to be solved in the utility model provides a kind of heat that can make full use of the combustion gas generation when using kitchen range, improves the gas cooker energy saving cover of heat utilization efficiency.

The technical scheme that solves the problems of the technologies described above is:

A kind of gas cooker energy saving cover, it is made up of back-up ring, lasso, and back-up ring is a cylinder, the internal diameter of back-up ring is greater than the outer ring of the burner of kitchen range, and lasso is circular, and lasso cylindrical chow scheme is placed on the suitable for reading of back-up ring, cooperate with the rim of the mouth of back-up ring, the inner circumferential edge of lasso is evenly distributed with a plurality of ventilation gap.

Above-mentioned gas cooker energy saving cover, there is frying pan at the edge suitable for reading of described back-up ring gap, and described lasso also has corresponding plane breach, has downward arc to connect at the two ends of breach, the radian of arc and frying pan are complementary the circular arc of gap, and the inner periphery of lasso is less than the diameter of frying pan.

Above-mentioned gas cooker energy saving cover, the excircle of described lasso have downward vertical flanging, and the end opening of flanging matches with the rim of the mouth of back-up ring, and the inner periphery of lasso is greater than the external diameter of steamer.

Above-mentioned gas cooker energy saving cover, the lower limb of back-up ring also is connected with inner ring, and inner ring is circular, and its excircle is less than the internal diameter of back-up ring, and matches with the outer ring internal diameter of kitchen range burner, is evenly distributed with the support in a plurality of supports the bottom of a pan at inner ring upper edge circumference.

After adopting this energy-saving cover, the heat overwhelming majority that fuel produces is dispersed from the ventilation gap of lasso around along the bottom of a pan, significantly reduces voluntarily and runs off, and therefore can use less firepower and reaches the effect of big firepower, has saved the energy.The utility model is simple in structure, and it is easy, cheap to make, and has good social benefit and economic benefit, is worthy to be popularized.

Mark is as follows among the figure: back-up ring 1, lasso 2, rim of the mouth 3, ventilation gap 4, frying pan are gap 5, arc 6, flanging 7, inner ring 8, support 9

The specific embodiment

Fig. 1,2 shows that the utility model is made up of back-up ring 1 and lasso 2.

Back-up ring 1 is a cylinder, is mounted on the outer ring of burner of kitchen range.The end opening of back-up ring 1 can be directly and the outer plane contact of kitchen range burner, at the uniform a plurality of passages of back-up ring 1 lower circumference, utilize the original stent support of the kitchen range burner the bottom of a pan, also can connect an inner ring 8 at the lower limb of back-up ring 1, the excircle of inner ring 8 matches with the outer ring internal diameter of kitchen range burner, is evenly distributed with the support 9 in a plurality of supports the bottom of a pan at inner ring 8 upper edge circumference.There is frying pan at the edge suitable for reading of the back-up ring 1 that shows among Fig. 1 gap 5, and this is the design of placement frying pan, and when using steamer, does not need this gap.Producer can dispose two kinds of back-up rings when producing this product, match with frying pan lasso and steamer lasso respectively, perhaps only dispose a kind of frying pan that has the back-up ring 1 of gap 5, the lower limb of while at the lasso 2 of steamer increases a washer that gap is mated with frying pan, with this gap shutoff, prevent that heat runs off.

Fig. 3,4,5 shows, the lasso 2 of placing frying pan is circular, lasso 2 cylindrical chow schemes are placed on the suitable for reading of back-up ring 1, cooperate with the rim of the mouth 3 of back-up ring 1, the inner circumferential edge of lasso 2 is evenly equipped with a plurality of ventilation gap 4, the inner periphery of lasso is less than the diameter of frying pan, and when frying pan was placed on the lasso 2 like this, flame and hot gas were discharged from ventilation gap 4 along the bottom of a pan.Because the top edge of back-up ring 1 has the frying pan of placement gap 5, therefore the lasso 2 of placing frying pan also has corresponding plane breach, there is downward arc 6 to connect at the two ends of breach, the radian of arc 6 and frying pan are complementary the circular arc of gap 5, the front end of arc 6 is against the side of frying pan, prevents that heat from overflowing gap 5 from frying pan.

Fig. 6,7 shows that the excircle of placing the lasso 2 of steamer has downward vertical flanging 7, and the end opening of flanging matches with back-up ring 1 rim of the mouth 3, and 2 of lassos are placed on the back-up ring.The inner periphery of lasso 2 is greater than the external diameter of steamer, and steamer is put into by lasso 2, and frame is on support 9, and flame and hot gas are discharged from ventilation gap 4 along steamer circumference side.
