Abstract

The utility model discloses an air-door type air return furnace which comprises a furnace bottom, a furnace wall, a furnace face plate and a furnace core arranged in the furnace wall. The furnace wall is arranged between the furnace bottom and the furnace face plate. A smoke exhaust box is arranged on the outer side of the furnace wall and is communicated with a cavity through a smoke vent in the furnace wall, and the cavity is formed by the furnace wall and the smoke exhaust box. An air door is arranged on one side of the lower portion of the smoke exhaust box. A smoke exhaust pipe is arranged on the top of the smoke exhaust box and is communicated with the smoke exhaust box. A check bridge is arranged at the bottom of the furnace wall. An ash box is arranged under the furnace bottom. A handle is arranged between the check bridge and the ash box. Due to the fact that the smoke exhaust box is arranged on the furnace wall, and the air door is arranged on the smoke exhaust box, when the air door is opened, an inner cavity of a furnace body can fully contact with the air so as to enable fuel to be fully burnt. When the air door is closed, the air-door type air return furnace can play a sealing role to the interior of the furnace body, prevents the fuel in the furnace body from freely burning, thereby having an energy-saving function.

Description

A kind of throttle type air return stove

Technical field

The utility model belongs to the combustion stove technical field, relates to a kind of domestic briquet stove, especially relates to a kind of throttle type air return stove.

Background technology

Along with the development of economic technology and improving constantly of living standards of the people, also obtain the development of advancing by leaps and bounds as requisite Domestic stove, stove and accessory miscellaneous has appearred in market.For increasing heating effect, it mostly is to increase heating, energy-saving effect by the mobile stroke that increases flue-gas that existing family adopts air return stove, but the air return stove of this structure exists combustion gas not enough, even smoke exhaust pipe easily stops up, thereby cause this kind stove to exist smoke discharging effect poor, stove fire burning is not vigorous, is difficult to satisfy coal stove and is used for the problem of cooking.

The utility model content

For addressing the above problem, the utility model provides a kind of throttle type air return stove.

A kind of throttle type air return stove, comprise furnace bottom, furnace wall, furnace panel and place combustion chamber in the furnace wall, described furnace wall places between furnace bottom and the furnace panel, the outside in the furnace wall is provided with smoking box, smoking box is communicated with by the cavity that the exhaust smoke hole on the furnace wall and furnace wall surround, and one side is provided with air door in the smoking box bottom, is provided with smoke exhaust pipe at the smoking box top, smoke exhaust pipe is communicated with smoking box, bottom, described furnace wall is provided with grate, and the furnace bottom below is provided with ash bin, is provided with handle between grate and ash bin.

Described air door is installed on the furnace wall by loose-leaf, so that open or close smoking box.

The described air door outside is provided be used to the handle of opening air door.

Described smoking box and air door the same side are equipped with clamp, and when air door was closed, rotatable clamp was locked with it.

The bell that described furnace panel is provided with the stove circle and is complementary with the stove circle, and be provided with venthole at the bell center.

The beneficial effects of the utility model are:

Compared with prior art, it is simple, easy to use to the utlity model has structure fabrication, reasonable in design, owing in the furnace wall smoking box is set, and at smoking box air door is set, when open air door is opened, the body of heater inner chamber is fully contacted with air, impel full combustion of fuel, stove fire is vigorous; When air door is closed, can play sealing function to body of heater inside, prevent body of heater fuel free combustion, thereby play energy-conservation effect.。
