Description

A kind of fireplace

Technical field

The utility model relates to fireplace manufacturing technology field, more particularly, relates to a kind of fireplace.

Background technology

Along with the raising of people's living standard, fireplace more and more has been subjected to people's welcome, and fireplace not only is used for heating, also can play certain beautification function to indoor environment.

Traditional fireplace is in the process of work, the firewood of burning is placed in the burner hearth, and fresh air inlet bubbling air in burner hearth by being arranged on burner hearth bottom, because the distributed areas of fresh air inlet are limited, so in the process of air-supply, air feeds from the bottom of burner hearth, is difficult to guarantee that all sites in the burner hearth can both bubbling air, causes to have the air-supply dead angle in the burner hearth.Particularly the edge of burner hearth is not owing to there are enough air, so it is slow to be in the firewood combustion at this position, and it is insufficient to burn.

In addition, existing fireplace is in the process of burning, the fresh air inlet that is arranged on burner hearth bottom directly communicates with the external world, so its intake is certain, the burning velocity of the uncontrollable fuel of this fireplace is not when in case the user uses fireplace (go out or sleep etc.), timber in the fireplace is still in burning, cause a large amount of consumption of firewood, and since fireplace light more loaded down with trivial details, so the user does not wish directly to extinguish fireplace again.

The utility model content

In view of this, the utility model provides a kind of fireplace, to solve the problem that has the dead angle of blowing when existing fireplace is worked.

In order to achieve the above object, the utility model embodiment provides following technical scheme:

A kind of fireplace comprises:

Burner hearth, the top of this burner hearth is provided with air inlet, and the bottom is provided with down air inlet;

Be arranged on the front end at the top of described burner hearth, and form the baffle upper plate of first inlet channel with the door of described fireplace, described first inlet channel communicates with described air inlet, and its port of export is towards the bottom of described burner hearth;

Be arranged on the chin spoiler on the bottom of described burner hearth, described chin spoiler is a notch plate, and its concave panel is towards the rear wall of described burner hearth;

Be arranged on the rear wall of described burner hearth, and second inlet channel that communicates with described air inlet down, the rear wall of described burner hearth is provided with the air admission hole that communicates with described second inlet channel.

Preferably, in the above-mentioned fireplace, described chin spoiler is an arc.

Preferably, in the above-mentioned fireplace, the top of described burner hearth is provided with the first pyrotechnics deflector and the second pyrotechnics deflector that is interspersed, and both form the zigzag flue that communicates with the chimney of this fireplace.

Preferably, in the above-mentioned fireplace, the described first pyrotechnics deflector and the second pyrotechnics deflector are parallel to each other.

Preferably, in the above-mentioned fireplace, the described air inlet of going up is provided with the air door that can regulate aperture with following air inlet.

Preferably, in the above-mentioned fireplace, described air door comprises air door body and air door regulating handle, and described air door regulating handle one end is fixed on the described air door body, and the other end rotatably is connected on the described burner hearth.

As shown from the above technical solution, the utility model embodiment provides in the fireplace, be provided with air inlet at the top of burner hearth, the bottom is provided with down air inlet, air enters into first inlet channel by last air inlet, the rear wall of burner hearth is provided with the air admission hole that communicates with second inlet channel, air is by being ventilated to burner hearth bottom by top in first inlet channel, second inlet channel is by the direction ventilation of the air admission hole on the rear wall to the door of fireplace, above-mentioned two kinds of ventilation air-flows form annular airflow in burner hearth, because the inlet air flow that is passed in the burner hearth has very big perturbation, realized inlet air flow is sent to every nook and cranny in the burner hearth, avoided having the air-supply dead angle in the burner hearth, made that fireplace firewood combustion in the process of work is more abundant.

In addition, in the fireplace that the utility model embodiment provides, last air inlet and following air inlet are provided with the air door that can regulate aperture, by the aperture of damper, and then regulate the air capacity that is passed in the burner hearth, realized the firewood controlled burning in the burner hearth, when the user does not use fireplace, the aperture of turning air door down makes that to reduce the air inlet fireplace is unlikely to extinguish, and has reduced the consumption of fireplace to firewood.
