Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a warm air stove. Background Art

[0002] The warm air stove is a stove used for indoor heating, heating the kang and cooking. It is a thin iron plate cover fixed on the ordinary cast iron stove, forming a space layer with the stove body, that is, a warm air box. The warm air box has a cold air inlet at the bottom, a warm air outlet and a warm air pipe at the top, which changes the radiation heat dissipation into directional warm air heating.

[0003] However, the heat is dissipated by the furnace body, and most of the heat in the furnace body will be discharged through the flue gas, so the heat utilization rate is not high. For this reason, we propose a warm air furnace. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a warm air stove.

[0005] The utility model provides the following technical solution: a warm air furnace, comprising a furnace body and a combustion chamber with a bracket installed inside the furnace body, a grate is provided at the bottom of the combustion chamber, and a collection bin for collecting furnace ash is provided in the furnace body below the bracket;

[0006] The side of the combustion chamber does not contact the interior of the furnace body, and a charging window is provided on the furnace body, through which fuel is added into the combustion chamber;

[0007] A plurality of heat-conducting pipes are provided at the top of the combustion chamber, and the heat-conducting pipes extend from both ends of the combustion chamber. A fan is installed on the outside of the furnace body, and the fan is connected to one end of the plurality of heat-conducting pipes through a pipeline. An air inlet is opened on the outside of the furnace body, and a smoke exhaust port is installed at the top of the furnace body, and the bottom end of the smoke exhaust port extends to the inside of the combustion chamber.

[0008] Preferably, a feed port is installed on the combustion chamber, and the feed port extends to the front side of the furnace body and is provided with a feed window.

[0009] Preferably, the inner wall of the furnace body is paved with heat-insulating material.

[0010] Preferably, the material collecting bin is of drawer design, and ventilation holes are provided on the front side of the material collecting bin, so that air can enter the material collecting bin and pass through the grate into the combustion chamber.

[0011] Preferably, the heat pipe is made of high temperature resistant heat conductive metal.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The warm air furnace is equipped with a collecting bin to collect the ash dropped from the grate for easy discharge. In addition, the outside air is drawn into the furnace body through the fan, so that the air contacts the combustion chamber and takes away the heat therefrom. Finally, the air is heated by the heat in the combustion chamber through the heat conduction pipe, and the hot air is discharged through the fan. The suction method is adopted to reduce the noise generated by the air flow. The air not only takes away the heat outside the combustion chamber, but also passes through the inside of the combustion chamber, which can further improve the utilization of heat.
