Abstract

The utility model relates to a household stove for cooking and heating, in particular to a household energy-saving stove. The invention solves the problem that the structural design of the existing domestic furnace is unreasonable, so that the fuel cannot be fully burned, which not only wastes energy, but also pollutes the environment. The household energy-saving furnace includes a chassis, a furnace body on the chassis and a furnace head on the upper part of the furnace body. A fire grate is arranged in the furnace body. There is an air duct between the furnace liner and the furnace body, and an annular burner with holes on it is arranged between the fire outlet on the upper part of the furnace liner and the burner at the bottom of the burner. The household energy-saving furnace forms a secondary circulation air path in the furnace by setting the air inlet, the furnace air duct and the annular burner, so that the fuel can be fully burned for the second time, and has the remarkable effect of saving energy and reducing pollution. It can be used for cooking and heating at home, especially suitable for popularization and application in rural areas.

Description

Household Energy Saving Furnace

technical field

The utility model relates to a household stove for cooking and heating, in particular to a household energy-saving stove.

Background technique

Existing domestic stove is usually made of burner head, stove body and chassis. Due to the unreasonable structural design, the existing domestic furnace fuel cannot be fully burned, which not only wastes energy, but also pollutes the environment.

Contents of the invention

The utility model provides a household energy-saving furnace in order to solve the problem that the structure design of the existing household furnace is unreasonable, so that the fuel cannot be fully burned, energy is wasted, and the environment is polluted.

The utility model is realized by adopting the following technical scheme: a household energy-saving furnace, including a chassis, a furnace body located on the chassis and a furnace head on the upper part of the furnace body. There is a furnace liner above the grate in the furnace body, an air duct is provided between the furnace liner and the furnace body, and a hole is provided between the fire outlet on the upper part of the furnace liner and the fire port at the bottom of the burner. Annular crater. When in use, open the air inlet under the furnace body, part of the natural wind enters the furnace through the grate, and the other part of the natural wind passes through the air duct between the grate, the furnace liner and the furnace body, and is sprayed out through the hole on the annular burner , so that the fuel can be fully burned for the second time at the annular burner and in the burner, so as to achieve the purpose of saving energy and reducing pollution.

The household energy-saving furnace described in the utility model forms a secondary circulation air path in the furnace by setting the air inlet located under the furnace body, the air duct between the furnace liner and the furnace body, and the annular burner, so that the fuel can be recycled Subsequent complete combustion has the remarkable effect of saving energy and reducing pollution. Compared with the existing ordinary household furnaces, the household energy-saving furnace described in the utility model can improve the thermal efficiency by dozens of times, and the furnace smoke can be reduced by about 40%. The household energy-saving stove can be used for cooking, and can also be used for household heating, conforms to national environmental protection standards, quality standards, and hygiene standards, and is especially suitable for popularization and application in rural areas.

Detailed ways

The household energy-saving furnace includes a chassis 1, a furnace body 2 on the chassis, and a furnace head 3 on the upper part of the furnace body. A fire grate 4 is arranged inside the furnace body, and an air inlet 5 is opened at the position below the furnace body. A furnace liner 6 is provided above, an air duct 7 is provided between the furnace liner 6 and the furnace body 2, and an annular ring with holes is provided between the fire outlet on the upper part of the furnace liner and the fire port at the bottom of the burner. Crater 8. The cross section of the furnace body 2 is square, and the air channels 7 between the furnace liner 6 and the furnace body 2 are distributed at the four corners of the furnace body 2, so that the structure of the furnace can be further optimized. The air inlet 5 is opened on the front of the furnace body 2 . The front of the burner 3 has a coal filling port 9, which is used to add coal or fire. Air inlet 5 and coal filling port 9 are provided with door, close the door on coal filling port 9 when using fire, open the door on air inlet 5; Can close the door on air inlet 5 when sealing fire. Same as the existing household stove, the burner 3 is provided with a smoke outlet, and the chassis 1 is provided with a pull-out ash hopper.
