Description

Firewood fireplace comprising bottom air inlet device

Technical Field

The utility model relates to the technical field of indoor heating, in particular to a firewood fireplace comprising a bottom air inlet device.

Background

Indoor firewood stove (heating cabinet, heating stove, fireplace etc.) heats the air in the stove through burning firewood and forms the high temperature, and the glass panel on the rethread furnace gate is with high temperature radiation to indoor, forms the effect of heating, and this kind of indoor firewood stove is fixed the heat insulating board on the stove outer covering inner wall mostly, carries out the heat insulation through the heat insulating board, and this kind of heat insulating type can't keep apart the heat completely, leads to stove outer covering surface temperature often to reach 150 ℃ more, and the scald easily takes place when the mistake touches, and the flue gas in this kind of mode stove is big because lack air combustion-supporting when rising in addition, and its flue gas discharge is big, combustion efficiency is low.

Disclosure of Invention

The utility model aims to overcome the defects of the prior art and provide the bottom air inlet device which is reasonable in structure and good in using effect and is used for the firewood temperature control furnace.

In order to achieve the above purpose, the technical scheme provided by the utility model is as follows: the utility model provides a firewood fireplace that contains bottom air inlet unit, it is including the stove outer covering, be equipped with the stove courage in the stove outer covering, reserve the heat exchange chamber between stove courage and the stove outer covering, the stove outer covering front side is equipped with the outer heating mouth that runs through in and out, the outer heating mouth outside is equipped with the furnace gate, the stove courage front side is equipped with the inner heating mouth that runs through in and out, connect through the heat-conducting cover between inner heating mouth and the outer heating mouth, the stove outer covering bottom is equipped with the bottom air inlet that runs through in and out, be equipped with the aviation baffle on the stove outer covering inner chamber wall of outer heating mouth top, reserve the air guide passageway between aviation baffle and the heat-conducting cover, be equipped with the furnace gate air guide mouth that runs through in and out on the stove outer covering of air guide passageway department.

The air deflector is obliquely fixed on the inner cavity wall of the furnace shell above the external heat supply port, and the oblique direction of the air deflector is consistent with the oblique direction of the top of the heat conduction cover.

The heat conducting cover is trapezoid with a small outside and a large inside, one larger end of the heat conducting cover is connected with the furnace pipe outside the inner heat supply port, and the smaller end of the heat conducting cover is connected with the furnace shell inside the outer heat supply port.

The bottom air inlet is positioned at the bottom of the furnace shell or at the lower part of the rear side wall.

After the scheme is adopted, when firewood in the furnace is combusted, air in the furnace is reduced, under the action of negative pressure, the air enters the heat exchange cavity from the air inlet at the bottom, heat exchange is carried out with high temperature on the furnace, air preheating is carried out, the temperature of the furnace shell can be reduced after the heat exchange cavity is adopted, the surface temperature of the furnace shell is controlled below 60 ℃, the air entering the furnace can be preheated, thus the combustion effect is better, the preheated air enters the air guide channel and is blown to the furnace door through the air guide channel, dust attached to the furnace door (glass panel) is blown off, the preheated air is blocked by glass and then reversely enters the furnace inner (the periphery of the heat guide cover can be designed into the air guide plate and the air guide opening of the furnace door according to the requirement), part of the hot air entering the furnace inner is risen to be mixed with smoke, the smoke is fully combusted, the smoke discharge amount is reduced, the other part of the hot air is contacted with the flame surface, the firewood is fully combusted, and the smoke is generated.
