Abstract

The utility model relates to a multi-function high efficiency energy saving stove, which is composed of a main stove, a far-infrared baking oven, a hot water tank, a heater and an air preheater. The utility model has the advantages of high thermal efficiency over 78%, time saving, small size, light weight and convenience. Cooking operations, such as frying, boiling water, cooking rice, baking food, etc., can be made at the same time on the same stove. The multi-function high efficiency energy saving stove can automatically cook rice and boil water, and meanwhile can be used for warming and automatically adjusting temperature when the multi-function high efficiency energy saving stove is sealed, which is an ideal household coal stove.

Description

Multi-functon high efficiency energy saving stove

The utility model belongs to the coal stove technical field among the mankind life article.

In considerable countries and regions, home-use coal stove is as the equipment of the cooking and heating.Because the existing coal stove thermal efficiency is not high, generally only be 60%, the highest by only 71%, therefore, there is every year a large amount of coal charges to be slatterned because of can not rationally utilizing.And the function of this class coal stove is few, can not carry out multiple cooking work simultaneously, uses this coal stove not only time-consuming, and inconvenient.

The purpose of this utility model is: the thermal efficiency that improves coal stove, use a coal stove, can carry out cooking, hot water simultaneously, cook or cooking work such as baked food, when banking up a fire, can cook automatically, boil water, also have heating simultaneously, regulate the function of humidity automatically.

The utility model and the structural difference of existing coal stove are: existing state-of-the-art coal stove is made up of combustion chamber, stove basin and boiler.And the utility model mainly is made up of several parts such as main stove, far-infrared oven, boiler, heating device, air preheater, chimney, ash buckets.

Main stove is made of rounded combustion chamber in cross section (4) and stove basin (5).Combustion chamber (4) inside and outside wall is coated with far ultrared paint.Air preheater (6) is two concentric drums with chimney (7), and the cylinder of the inside is chimney (7) (seeing Fig. 1, Fig. 2), on chimney (7) outer wall strip fin (1) is arranged.It is foursquare combustion chamber cover (8) that combustion chamber (4) outside is with a cross section, and four jiaos of spaces between combustion chamber (4) and the combustion chamber cover (8) are secondary air duct, and four sides of combustion chamber cover (8) all have the secondary eye of wind (9) (Fig. 2,3).

When coal during in combustion chamber (4) internal combustion, extraneous air enters air preheater (6) by air admission hole (12), flue gas in air and the chimney (7) is reverse and flow, air themperature after the preheating can reach more than 120 ℃, air after most of preheating enters in the combustion chamber (4) combustion-supporting by grate (10), after being heated once more, secondary air duct rises to combustion chamber (4) top on a small quantity, by the secondary eye of wind (9) ejection (see figure 2), the gas-fired that combustion chamber (4) top is not fired, pyrotechnics is through entering flue again around the bottom of a pan and the pot, after fully carrying out heat exchange, become waste gas and discharge by chimney (3).

The baking box of coal stove (11) lays respectively at combustion chamber (4) both sides with boiler (12), and combustion chamber and combustion chamber cover are close in the baking box of rectangular shape and the side of boiler, and the upper side of baking box and boiler is close to the bottom of stove basin (5).On baking box and side that the combustion chamber cover pastes mutually, there are two conducting strips to be close to two sides in addition of combustion chamber cover respectively, and connect mutually with the combustion chamber cover, so that the radiant heat of combustion chamber is passed to baking box more with screw.The inwall of baking box is coated with far ultrared paint.Baking box (11) and boiler (12) are sealed in the furnace shell, (Fig. 4) with insulation material (13).

On the stove basin (5) of coal stove a thermal loop (14) is arranged, thermal loop and Da Gai (15) link together, and six equally distributed cigarette holes (16) are arranged on the thermal loop, and the coal stove below has the ash bucket (17) of a cuboid to place outside the coal stove housing.(Fig. 4).

One mobilizable heating device (18) is arranged (Fig. 5) at the fire door place of coal stove, the rosette (19) that it all has a spirality fin by a upper and lower surface (Fig. 6) and the lid (20) that has the air intake aperture around constitute.Existing coal stove is that body of heater and bell are burnt heat, and with thermal-radiating mode heating, the consumption coal is many, and heating effect is poor.Heating system of the present utility model is that air heat is become heating installation, deliver to heating zone heating, the conveying of heating installation has free convection and forced convertion dual mode, and it is indoor that as long as the former be placed on stove, snorkel just can be sent the clean heating installation about 120 ℃ continuously, can supply 40m ²Room heating; The latter, stove can be placed on the kitchen, with pipeline and warm feeder heating installation is delivered to indoor heating, can place the electric fan of a 15～20W in the warm feeder, and to strengthen the conveying of heating installation, fan can be made thermantidote in hot day and use.During heating, the water vapour in the boiler is imported in the heating device with a short tube, just can regulate humidity automatically.This coal stove is except that heating device (18) is movable, and other parts all are coupled as one regularly.

The Multi-functon high efficiency energy saving stove that the utility model proposes, its overall thermal efficiency be more than 78%, can carry out simultaneously cooking, hot water, cook or the cooking work such as baked food, and when automatically banking up a fire, just can Automatic-cooking, boil water. Opened fire 2～3 minutes, flare can rise to several cun high. This coal stove have save time, make things convenient for, the characteristics of efficient, health, six mouthfuls family, three honeycomb briquettes of one day burning have not only been carried out food, also at any time have a large amount of boiling water, hot water to use. This coal stove volume is little, in light weight, and cost is lower, is well suited for family and uses.
