DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of a non-powered pellet heater according to the present invention will be described in detail with reference to the accompanying drawings.

Prior to the description of the present invention, the term "fuel" in this specification refers to wood chips, pellets and the like, and pellets are exemplarily described in this specification, but it is obvious that other fuels mentioned above are applicable to the present invention .

FIG. 1 is a perspective view of one embodiment of a non-powered pellet furnace according to the present invention, and FIG. 2 is a partially cutaway perspective view of a fuel chamber and a combustion chamber of the embodiment of FIG.

The non-powered pellet stove 100 according to the present invention includes a fuel chamber 110, a combustion chamber 120, and a rod 130 as shown in FIGS.

The fuel chamber 110 is connected to the hopper H and receives a plurality of fuels 10 from the hopper H and discharges the fuel in one direction. A plurality of fuels (10) are injected into the hopper (H) through the upper part of the hopper (H). The hopper H is capable of selectively coupling the fuel to the fuel chamber 110 according to the amount of the plurality of fuels 10 accommodated therein. The hopper H is coupled to the open upper portion of the fuel chamber 110 using a coupling means such as a bolt. The fuel chamber 110 is obliquely inclined in a tubular shape and receives a plurality of fuels 10 from the hopper H. The reason why the fuel chamber 110 is tilted obliquely is to prevent the plurality of fuels 10 supplied from the hopper H from being loaded in the fuel chamber 110 and to be beautiful in appearance. The fuel chamber 110 may be divided into a preheated space and a non-preheated space. The preheated space refers to a space near the combustion chamber 120, and the unheated space is a space away from the combustion chamber 120. A plurality of ventilation holes 111 are formed in the side surface of the fuel chamber 110 so as to allow air to flow into the fuel chamber 110. The air introduced into the fuel chamber 110 through the vent hole 111 flows along a plurality of particles of the fuel 10 accommodated in the fuel chamber 110 to promote combustion of the fuel 10 . The shielding plate 112 is bonded to the outer wall of the fuel chamber 110 where the vent holes 111 are formed to cover the vent holes 111, respectively. The shielding plate 112 is a plate that is bent so that its cross section is square, and has a size such that a plurality of ventilation holes 111 are not visible from the outside, and is coupled through welding means such as welding or bolt. The shielding plate 112 is designed to provide a beautiful appearance of the fuel chamber 110 in which a plurality of ventilation holes 111 are formed. The present invention is exemplified in that the shielding plate 112 is a plate member bent in a rectangular shape in cross section so as to give a beautiful appearance to the fuel chamber 110 in which the vent hole 111 is formed, A plate material bent in a circular shape in cross section, a plate material bent in a triangular shape in cross section, and the like, as well as a curved plate material of another shape.

The combustion chamber 120 is formed with two inlets 121 and 122 and one outflow port 123. One inlet 121 is fixed to communicate with the fuel chamber 110 and is discharged from the fuel chamber 110 Fuel 10 is burned. The fuel 10 discharged from the fuel chamber 110 is ignited by using an ignition device such as a gas torch in a state of being stacked on the combustion chamber 120. One inlet 121 of the two inlet ports 121 and 122 formed in the combustion chamber 120 is a fuel inlet port 121 through which a plurality of fuels 10 flows in communication with the fuel chamber 110, (122) is an air inlet (122) communicating with the outside to introduce outside air. One outlet 123 formed in the combustion chamber 120 communicates with the heat dissipation chamber 140 described below. One opening and closing door 124 is formed in the combustion chamber 120. The opening and closing door 124 of the combustion chamber 120 is openable and closable to the air inlet 122. The opening and closing door 124 of the combustion chamber 120 is formed with an inlet hole 124a. The inflow hole 124a introduces outside air into the combustion chamber 120 to help burn the fuel 10. [ The air is introduced into the combustion chamber 120 through one inflow hole 124a formed in the opening and closing door 124 of the combustion chamber 120. However, The inlet hole 124a may be formed in the opening / closing door 124 of the combustion chamber 120 as long as it is possible. The opening and closing door 124 of the combustion chamber 120 ignites a plurality of fuels 10 laminated in the combustion chamber 120 while partially opening from the air inlet 122 and then closes the air inlet 122 again . The combustion chamber 120 can be divided into a preheating space on the basis of the combustion plate 125 and a combustion space below the combustion chamber. The combustion plate 125 is a U-shaped plate member and is fixed to a lower portion of the fuel inlet 121 which is elongated and communicates with the interior of the fuel chamber 110. The combustion plate 125 smoothes the combustion of the fuel 10 because the combustion space is ensured by the combustion plate 125 and the air supply is smooth. One end of the combustion plate 125 in the width direction and one end in the longitudinal direction are fixed to the combustion chamber 120 so that a plurality of fuels 10 discharged from the fuel chamber 110 are stacked at both ends in the width direction and at one end in the longitudinal direction, Some of the plurality of fuels 10 pass through the combustion plate 125 and fall to the bottom of the combustion chamber 120. The fuel 10 that has fallen on the bottom of the combustion chamber 120 is converted into fine particles 10a due to combustion. Although the combustion plate 125 is made of a U-shaped plate to facilitate combustion, the present invention is not limited to the E-shaped plate, the T-shaped plate, the H-shaped plate, the mesh net, As shown in FIG.

The rod 130 is rod-shaped and fixed to both ends of the inlet 121 of the combustion chamber 120 communicating with the fuel chamber 110 in the width direction. The rod 130 serves to suppress the passage of a plurality of fuels 10 discharged from the fuel chamber 110 and to secure an air flow space for the air to flow into the combustion chamber 120. The plurality of fuels 10 are kept in the combustion state because air flows smoothly due to the air flow space secured in the combustion chamber 120. The rod 130 can be selectively replaced with any one of a mesh network, a pipe, and a pipe. The rod 130a may be deformed as shown in Fig. The rod 130a is made of two or more pieces, and the distance between the rods 130a is such that the passage of the plurality of fuels 10 can be suppressed. This makes it possible to ensure more air flow space than the air flow space ensured by the single rod 130 described above, so that combustion is more efficient.

The heat dissipation chamber 140 communicates with the exhaust port 123 of the combustion chamber 120 and exhausts the ash 10a and the exhaust gas through the exhaust port 123 of the combustion chamber 120. The ash material 10a flows into the heat dissipation chamber 140 ), And the exhaust gas is discharged to the outside. The heat dissipation chamber 140 is formed with one discharge port 141 and one opening / closing door 142. One discharge port 141 formed in the heat dissipation chamber 140 is an exhaust gas discharge port 141 formed in the upper portion of the heat dissipation chamber 140 to discharge the exhaust gas discharged from the combustion chamber 120. The exhaust gas outlet 141 is separately connected to the pipe-shaped communication pipe 143 to discharge the exhaust gas to the outside. One opening and closing door 142 formed in the heat dissipation chamber 140 can be opened and closed in a lower portion of the heat dissipation chamber 140 and a circular glass plate 142a is formed. The glass plate 142a is transparent so that the internal condition of the heat dissipation chamber 140 can be visually confirmed. The glass plate 142a has a circular shape and the internal condition of the heat dissipation unit 140 is visually checked. However, if the internal condition of the heat dissipation unit 140 can be visually confirmed, a glass plate 142a A triangular shape, a rectangular shape, and the like, as well as other shapes. The opening and closing door 142 of the heat dissipation chamber 140 is kept closed during the burning process and is opened when the material 10a stacked in the heat dissipation chamber 140 is removed. The material 10a stacked on the heat dissipation chamber 140 is removed by repeatedly entering and exiting the opening and closing door 142 of the heat dissipation chamber 140 in an opened state. When the removal of the ash 10a is completed, the opening and closing door 142 of the heat dissipating chamber 140 is closed and the operation of burning the fuel 10 again is performed.

The cooking chamber 150 is formed on the top of the combustion chamber 120 and is formed between the fuel chamber 110 and the heat dissipation chamber 140. The cooking platform 150 can directly place the object to be cooked in a space heated by the heat generated by the combustion of the fuel 10, or cook the food by placing the cooking utensil.
