Description

Air-intake combustion-supporting firewood stove

Technical Field

The utility model relates to the technical field of combustion stoves, in particular to an air-inlet combustion-supporting firewood stove.

Background

The firewood stove for burning wood is one common kitchen utensil in village area or in field camping, and has single wall structure, firewood adding port in the wall and combustion chamber in the hearth.

However, the conventional firewood stove has the following disadvantages: firstly, the fire power of the part which obtains the combustion supporting of the air blower in the combustion chamber is strong, the fire power is poor at the part far away from the air inlet position of the air blower, and the firewood combustion effect in the combustion chamber is not uniform; secondly, the furnace wall is burned to be red when the firewood stove burns, and a large amount of heat is emitted to cause heat loss; thirdly, a large amount of flue gas and fly ash generated in the combustion chamber are blown up by the air flow of the air blower and overflowed from the upper part, so that the surrounding environment of the firewood stove is bad, and the use is influenced.

Disclosure of Invention

The utility model aims to provide an air-intake combustion-supporting firewood stove which has the advantages of good combustion effect, less heat loss, thorough flue gas collection and emission and the like.

In order to achieve the purpose of the utility model, the technical scheme adopted is as follows:

an air inlet combustion-supporting firewood stove, wherein an annular air cavity is formed in a space between the outer wall and the inner wall, a combustion chamber is arranged in an intermediate space surrounded by the inner wall, and a plurality of air inlet combustion-supporting holes are formed in the inner wall; an air inlet pipe is arranged at the outer side of the outer wall and leads to the air cavity; the outer wall is provided with a firewood adding port, and the bottom of the outer wall is provided with a plurality of support feet for supporting the furnace body.

The utility model changes the structure that the traditional blower blows air into the combustion chamber directly, but takes the annular air cavity as the middle structure of air intake, and the annular air cavity plays the following roles: firstly, air for air intake and combustion supporting enters a combustion chamber in all directions from all directions, so that the burnt firewood can be comburedly supported by fresh air at all positions, but in the traditional combustion chamber, the position blown by the air blast burns vigorously, and the position not blown by the air blast is still anoxic; and secondly, the annular air cavity also forms a hollow heat insulation layer, heat in the combustion chamber cannot easily permeate out from the outer wall and overflow, cold air is continuously injected into the annular air cavity, and the air is introduced into the combustion chamber after being heated, which is equivalent to the combustion heat to form internal circulation for heating again, so that the energy-saving effect is remarkable.

The air inlet direction of the air inlet pipe is the tangential direction of the annular air cavity. The air entering the annular air cavity tangentially reaches the positions of the air inlet combustion-supporting holes along the annular inner wall, and air inlet is smooth and free from obstruction.

The air cavity is positioned at the middle lower part of the firewood stove, the upper end face of the inner wall is lower than the end face of the firewood stove top, and a space ring is arranged on the annular plane of the upper end of the inner wall. The function of the spacer ring is that: the heat at the heating furnace mouth is concentrated to prevent flame from being sprayed outwards, the spacer is also provided with a plurality of through holes, and the flue gas of the combustion chamber can still enter the smoke outlet to be discharged through the through holes.

And a plurality of air inlet combustion-supporting holes are formed in the annular plane of the upper end of the inner wall. Fresh air can be upwards sprayed out through the air inlet combustion-supporting holes on the upper end face, and combustion supporting is carried out on the upper area of the combustion chamber.

And a smoke outlet communicated with the combustion chamber is arranged on the outer side of the outer wall. The smoke outlet is used for discharging the smoke generated in the combustion chamber to a place through the pipeline for being discharged remotely, so that the influence of the smoke overflow on the surrounding environment of the cooking range is greatly reduced.

The bottom of the combustion chamber is provided with an ash falling port which leads to the external ground, and the ash falling port is provided with a movable ash falling cover. When the ash collecting device is in a working state, the ash collecting cover is lifted, and after the ash collecting device is used, ash in the combustion chamber is cleaned by lifting the ash collecting cover, and ash is cleaned out from the ash collecting port.

Handles are arranged on the two outer sides of the outer wall. The stove is convenient to move.

The technology of the application has the characteristics and advantages compared with the prior art:

1. the utility model changes the air path of blowing combustion supporting by arranging the annular air cavity, so that the air intake combustion supporting is more uniform, the firewood combustion is more sufficient, and the purposes of improving the heat efficiency and saving the energy are achieved.

2. The annular air cavity forms a heat insulation layer, so that heat in the furnace is not easy to leak, internal heat circulation is formed, the heat efficiency is further improved, and energy sources are saved.

3. Most of the smoke generated in the combustion chamber can be discharged through the smoke discharge pipe, and the surrounding environment of the stove is effectively improved.
