Abstract

The utility model relates to a kuppe gas-saving cooker, which relates to a plurality of kinds of energy-saving cookers used for gas burners and which can reduce the heat loss of the cooker and increase thermal efficiency. The utility model is characterized in that the outer surface of the cooker is fixed with an outer cover to make a space channel formed between the cooker and the outer cover (kuppe); waster hot flue gas passes through the space channel to carry out full heat exchange with the outer surface of the cooker and is exhausted from the top of the kuppe; the bottom edge of the kuppe and the surface of the gas burner are provided with space used as a ventilating hole to make the gas burned fully. The inner surface of the kuppe is provided with an insulating layer which has the function of thermal insulation to the waste hot flue gas and the cooker, and the utility model has the advantage of better effect of gas saving.

Description

The kuppe gas-saving cooker

The utility model relates to several energy-saving pots of using on the gas cooker, and promptly serial solar term pan is owing to belong to a total inventive concept, according to 5. bar of " patent application notice " 31 pages the, so concurrent application.This pan comprises three kinds of pots: 1. kuppe solar term frying pan; 2. kuppe solar term boiled water pot; 3. kuppe solar term pressure cooker

The pan that uses on the present gas cooker, the thermal efficiency is very low, reason mainly contains: the thermal loss that most of heat causes along with the space of the hot flue gas after combustion gas (vial road coal gas or the liquefied gas) burning around being dispersed into very soon also has the surperficial self heat of pot to distribute and also causes thermal loss.

The utility model purpose provides the pan of new structure, heat was dispersed into the thermal loss that surrounding space causes very soon with waste heat flue gas after it can prevent fuel gas buring effectively, reach the surperficial self heat of pot and distribute the heat loss that causes, thereby improve the thermal efficiency of pot, reach the purpose of saving combustion gas.

The utility model purpose is achieved in that pot body outer surface is fixed with an outer cover, also claim kuppe, the shape of outer cover does not have to be strict with different variation of pot shape (hood-shaped shape is all inequality for Fig. 1, Fig. 2, Fig. 3) with cooperating with it at home and abroad, as long as make and between pot body and outer cover, form a spatial channel, because waste heat flue gas is lighter, so can up flow, and after carrying out sufficient heat exchange with pot body outer surface, discharge by this spatial channel top along this spatial channel.

Steam vent is arranged at the outer cover top, and outer cover base and kitchen range face will have the space as passage, in order to circulation of air, combustion gas can fully be burnt.Outer cover inner surface also has heat-insulation layer.Can reduce scattering and disappearing of the surperficial heat of pot, and waste heat flue gas is had insulation effect.

The utility model need only be fixed a kuppe at former pot body outer surface, so structure is simpler.Owing to be conceived to form gas channel and can carry out sufficient heat exchange, be applicable to the energy-conservation of multiple pot with the pot outer surface.Improve more than 25% through measuring evenly heat efficient, also have this pan on coal stove, to use also and can reach purpose of energy saving.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing.

Fig. 1 is the cutaway view and the schematic diagram of the kuppe solar term frying pan that the utility model proposes;

Fig. 2 is the cutaway view and the schematic diagram of the kuppe solar term boiled water pot of concurrent application;

Fig. 3 is the cutaway view and the schematic diagram of the kuppe solar term pressure cooker of concurrent application.

Elaborate below in conjunction with Fig. 1: this gas-saving cooker comprises a pot body (1), pot handle (2), fix place cover (5) by securing member (3) (4) at pot body (1) outer surface and make and form spatial channel (6) between pot body and the outer cover, waste heat flue gas upwards flows and carries out being discharged by cover (5) top after the sufficient heat exchange with pot body (1) outer surface along direction shown in passage (6) arrow.

Outer cover (5) top has the kitchen range face of steam vent (7) outer cover (5) base and gas range (10) must leave passage (9) in order to circulation of air, combustion gas can fully be burnt, carbon monoxide content can not exceed standard, and outer cover (5) inner surface also has heat-insulation layer (8) that useless flue gas and pot body (1) are had insulation effect.

Fig. 2 is the separable connection except that pot body (11) pot handle (12) outer cover (15) and outer cover (15) top (15) different with Fig. 1 corresponding component shape, and all the other structures are all identical with operation principle and Fig. 1, just do not elaborate at this.

Elaborate below in conjunction with Fig. 3: this solar term pressure cooker comprises that a pot body (21) pot handle (22) fixes an outer cover (25) at pot body (21) outer surface by securing member (23) (24), outer cover top (23) is located to the separable conical surface connects with cylinder so that the pot cover folding with align automatically.

Outer cover (25) top has the kitchen range face of steam vent (27) outer cover (25) base and gas range (30) to have passage (29) outer cover (25) inner surface that heat-insulation layer (28) is arranged.

Air bleeding valve (31) (32) (33) can be adjusted the combined part of pressure at expulsion; it is made up of little valve body (31) (weight has only half of usual pressure pot air bleeding valve) and two trimmers (32) (33); increase and decrease trimmer (32) (33) can be adjusted pressure at expulsion; usually promptly can exhaust at half pressure of usual pressure pot; can cease fire after the exhaust; at this moment outer cover (25) heat-insulating property plays a role; make a pot interior long period maintain pressure; as long as have pressure then kettle temperature all more than 100 ℃; still continue cooking; utilize the steam waste heat thereby reach, further improve the effect of the thermal efficiency.
