Field of the Invention The present invention relates to a portable pellet stove, and more particularly, to a portable pellet stove which can be easily installed and dismantled, prevents backfire during pellet combustion, and has high thermal efficiency, and can be used indoors and outdoors.

Recently, pellets made of various materials, such as waste wood and waste resins, are very inexpensive, have high calories, and are easy to manage. Recently, the use of pellets as a fuel is increasing.

In particular, as interest in camping has increased, interest in pellet stoves has steadily increased.

As such, the furnace using pellets as a raw material is simply composed of a cylindrical body having a combustion chamber formed therein, and an exhaust pipe connected to the main body, and when pellets are introduced into the main body through an inlet, heat generated while the pellets are burned in the combustion chamber It is transmitted to the outside through the circumferential surface of the body to be heated.

However, such a pellet stove is difficult to completely burn the pellet, so that not only soot or soot is generated a lot, there is a problem that the thermal efficiency is low and it is very difficult to use for other purposes than heating.

On the other hand, Patent No. 10-1080198 has been introduced for a pellet stove with a high thermal efficiency, but the structure of supplying pellets from the vertical top was not able to solve the backfire phenomenon occurs during the combustion of the pellet, it does not solve the backfire phenomenon The gas problem that still occurred was still present.

The technical problem to be solved by the present invention is to provide a portable pellet stove that can solve the backfire phenomenon occurring during the combustion of the pellet, thereby reducing the amount of gas emissions.

Another technical problem to be solved by the present invention is to provide a portable pellet stove that can be easily installed and dismantled, easy to store and carry, very convenient for use indoors and outdoors, and can quickly perform first aid. The purpose is.

Another technical problem to be solved by the present invention is to form a bending structure bent or bent at least a plurality of flame passing structure, so that the flame stays in the pellet stove for a long time portable pellet stove that can increase the thermal efficiency The purpose is to provide.

In order to achieve the above object, the portable pellet stove of the present invention, a pellet inlet is provided at the top, a combustion chamber is provided in the diagonal direction of the lower portion of the pellet inlet, the upper portion of the combustion chamber and the lower side of the combustion chamber air Combustion unit formed with a supply hole; A supply unit connected to the pellet inlet for supplying pellets; A supply guide plate for guiding the pellets supplied from the supply part to be diagonally transferred to the combustion chamber; A heat transfer part in which one end part communicates with the combustion part, and flames and gases generated during combustion of the pellets are transferred; And a pipe connection part communicating with the other end of the heat transfer part and discharging the gas generated from the combustion part, wherein the supply part is detachably coupled to the pellet inlet, and the pellet is connected to the pellet inlet through the pellet inlet. A supply hole configured to be opened and closed to supply is formed, and the portable pellet stove is usually housed therein.

According to the present invention as described above, by forming the supply of pellets as fuel to be supplied along the inclined surface from the upper side rather than the vertical upper portion, it is possible to solve the backfire phenomenon occurring during the combustion of the pellets, the air inflow into the combustion chamber In addition, it is possible to reduce the amount of gas discharged by being formed to be supplied at the same time at the bottom to induce complete combustion.

In addition, it is easy to install and dismantle, easy to store and carry, so it is very convenient to use indoors and outdoors, and can quickly perform first aid.

In addition, by forming a bending structure in which at least a plurality of structures through which the flame passes is bent or bent, the flame stays inside the pellet stove for a long time, thereby improving thermal efficiency.
