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 an exploded perspective view of an embodiment of a non-powered pellet stove according to the present invention, and FIG. 2 is a perspective view of the embodiment of FIG.

The non-powered pellet heat stove 100 according to the present invention includes a fuel chamber 120, a combustion chamber 130, a heat dissipation chamber 140, and a fuel blocking member 150, as shown in FIGS. 1 to 5.

The fuel chamber 120 includes a hopper 110 for receiving a plurality of fuels 10 and a plurality of fuels 10 supplied from the hopper 110 by being coupled to the hopper 110 to be discharged in one direction. The hopper 110 is in the form of a supersonic light bulb, and a plurality of fuels 10 are injected and accommodated through the upper part. The hopper 110 is coupled to the fuel chamber 120 by selectively defining a capacity according to the amount of fuel 10 to be received. The hopper 110 is joined to the open upper portion of the fuel chamber 120 by tightening with a coupling means such as a bolt. The fuel chamber 120 is obliquely inclined in a tubular shape and receives a plurality of fuels 10 from the hopper 110. The reason why the fuel chamber 120 is tilted obliquely is to prevent the plurality of fuels 10 supplied from the hopper 110 from being loaded in the fuel chamber 120 and to be beautiful in appearance. The fuel chamber 120 may be divided into a preheated space and a non-preheated space. The preheated space refers to a space near the combustion chamber 130, and the unheated space is a space away from the combustion chamber 130. A plurality of vent holes 121 are formed in the side surface of the fuel chamber 120 so that air flows into the fuel chamber 120. The air introduced into the fuel chamber 120 through the vent hole 121 flows along a plurality of particles of the fuel 10 accommodated in the fuel chamber 120 to promote the combustion of the fuel 10 . The shielding plate 122 is coupled to the outer wall of the fuel chamber 120 in which a plurality of vent holes 121 are formed to cover the vent holes 121. The shielding plate 122 is a plate that is bent to have a square cross section and is formed to have a size such that a plurality of ventilation holes 121 are not visible from the outside and are coupled through welding means such as welding or bolt. The ventilation hole 121 formed in the fuel chamber 120 may be formed by cutting the ventilation hole 121 formed in the fuel chamber 120. In this case, As long as it can be covered, it can be deformed into a plate material bent in a circular shape in cross section, a plate material bent in a triangular shape in cross section, or the like, as well as a curved plate material in another shape.

The combustion chamber 130 is formed with two inlets 131 and 132 and one outflow port 133. One inlet 131 is fixed to communicate with the fuel chamber 120 and is discharged from the fuel chamber 120 Fuel 10 is burned. The fuel 10 discharged from the fuel chamber 120 is ignited by using an ignition device such as a gas torch in a state of being stacked on the combustion chamber 130. One inlet 131 of the two inlets 131 and 132 formed in the combustion chamber 130 is a fuel inlet 131 through which a plurality of fuels 10 flow into the fuel chamber 120, (132) is an air inlet (132) communicating with the outside to introduce outside air. One discharge port 133 formed in the combustion chamber 130 communicates with the heat dissipation chamber 140. The outlet 133 of the combustion chamber 130 is arranged so as to send the ash 10a generated by the combustion in the combustion chamber 130 and the exhaust gas toward the heat dissipation chamber 140 communicated with the discharge port 133 of the combustion chamber 130 . One opening and closing door 134 is formed in the combustion chamber 130. The opening and closing door 134 of the combustion chamber 130 is openably and closably formed in the air inlet 132. The opening and closing door 134 of the combustion chamber 130 is formed with an inflow hole 134a. The inflow hole 134a introduces outside air that helps combustion of the fuel 10 into the combustion chamber 130. The air is introduced into the combustion chamber 130 through one inflow hole 134a formed in the opening and closing door 134 of the combustion chamber 130. However, The inflow hole 134a may be formed in the opening / closing door 134 of the combustion chamber 130 as long as it can inflow the inflow hole 134a. The opening and closing door 134 of the combustion chamber 130 ignites a plurality of fuels 10 stacked in the combustion chamber 130 while partially opening from the air inlet 132 and then closes the air inlet 132 again . The combustion chamber 130 can be divided into a preheating space on the basis of the combustion plate 135 and a combustion space below the combustion chamber 130. The combustion plate 135 is a U-shaped plate member and is fixed to a lower portion of the fuel inlet 131 which is elongated and communicates with the interior of the fuel chamber 120. The combustion plate 135 smoothes the combustion of the fuel 10 because the combustion space is ensured by the combustion plate 135, so that the air supply is smooth. One end of the combustion plate 135 in the width direction and one end in the longitudinal direction thereof are fixed to the combustion chamber 130 so that a plurality of fuels 10 discharged from the fuel chamber 120 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 135 and fall to the bottom of the combustion chamber 130. The fuel 10 that has fallen on the bottom of the combustion chamber 130 is converted into the fine particle material 10a due to the combustion. The present invention exemplifies that the combustion plate 135 is made of a U-shaped plate material to facilitate combustion, but it can be an E-shaped plate, a T-shaped plate, an H-shaped plate, a mesh net, As shown in FIG.

The heat dissipation chamber 140 is fixed to communicate with the discharge port 133 of the combustion chamber 130 and has a discharge port 141 and a single opening and closing port 142. The discharge port 141 is connected to the combustion chamber 130 And exhausts the exhaust gas generated by the combustion of the exhaust gas. One exhaust port 141 formed in the heat dissipation chamber 140 is formed in an upper portion of the heat dissipation chamber 140 as an exhaust gas exhaust port 141 for exhausting the exhaust gas discharged from the combustion chamber 130. The exhaust gas outlet 141 is separately connected to the pipe-shaped communication pipe 141a. The heat dissipation chamber 140 discharges the material 10a generated by the combustion in the combustion chamber 130 together with the exhaust gas discharged to the discharge port 141 of the heat dissipation chamber 140 and stacks them. The opening and closing door 142 of the heat dissipation chamber 140 is formed at the lower portion of the heat dissipation chamber 140 so as to be openable and closable, and a circular glass plate 142a is formed. The opening and closing door 142 of the heat dissipation chamber 140 is kept closed in the process of burning 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 open / close door 142 of the heat dissipation chamber 140 in an opened state using a separate material remover. The heat dissipation chamber 140 closes the opening / closing door 142 of the heat dissipation chamber 140 when the removal of the ash 10a is completed using the remover equipment. 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 fuel block 150 is provided with a through hole 111 at a lower portion of the hopper 110 and cuts off a plurality of fuels 10 supplied through the through hole 111 to the fuel chamber 120. The fuel block 150 is installed at a lower portion of the hopper 110 so that the firepower generated during the combustion process in the combustion chamber 130 can not be exceeded. The fuel blocking member 150 is formed of a handle 151 and a plurality of shut-off bars 152, and has a fork shape. The knob 151 is formed to be elongated and is bent to have a square cross section, and is easy to grasp. The plurality of shut-off bars 152 are formed in a bar shape and are elongated like the knob 151. One end of each of the plurality of shut-off bars 152 is fixed to one end in the width direction of the knob 151, and the other end is formed in a sharp manner. The reason why the other end of the shut-off bar 152 is formed in a sharp manner is to allow the fuel to easily enter into a space between a plurality of fuel particles 10 accommodated in the hopper 110. The fuel blocking member 150 blocks the plurality of fuels 10 installed in the hopper 110 when the combustion is stopped. A plurality of shut-off bars 152 fixed to the knob 151 are brought into close contact with the through-holes 111 of the hopper 110 while holding the knob 151, The plurality of shut-off bars 152 pass through the through-holes 111 of the hopper 110 by pushing them toward the hopper 110. A plurality of shut-off bars 152 passing through the through-holes 111 of the hopper 110 collects a plurality of fuels 10 accommodated in the hopper 110 and blocks the inside of the hopper 110. As a result, the plurality of fuels 10 required for combustion are no longer supplied toward the fuel chamber 120, so combustion is stopped. On the contrary, when the combustion is proceeded, the knob 151 for cutting off the inside of the hopper 110 is detached from the hopper 110 together with the plurality of shut-off bars 152 while grasping the knob 151. As a result, a plurality of fuels 10 necessary for combustion are supplied toward the fuel chamber 120, and the combustion proceeds again. The present invention is exemplified in that the shut-off bar 152 is formed in a cylindrical shape to suppress the passage of the fuel 10. However, if the fuel 10 can be prevented from passing therethrough, . The fuel blocking member 150 'may be deformed in position to block the fuel 10 as shown in FIG. The fuel blocker 150 'is provided with a through hole 123 at an upper portion of the fuel chamber 120 and passes through the through hole 123 of the fuel chamber 120 to be supplied from the hopper 110 to the fuel chamber 120 Thereby shutting off the plurality of fuels 10 to be supplied. The fuel blocking member 150 'has the same function as the fuel blocking member 150 passing through the above-described hopper 110, but has a different position. The fuel blocking member 150 'is installed on the upper portion of the fuel chamber 120, which is high enough that the thermal power generated during the combustion process in the combustion chamber 130 can not be exceeded.

The support rod 160 is fixed to the inside of the hopper 110 and is fixed to the lower side of the through hole 111 of the hopper 110. The support rod 160 passes through the through hole 111, Support the end. The support rod 160 prevents the deflection of the shutoff rod 152 of the fuel blocking member 150 due to the weight of the fuel 10 supplied from the upper portion of the hopper 110. The axis of the support rod 160 and the axis of the shutoff rod 152 of the fuel blocking member 150 are orthogonal to each other. It is possible to prevent the deflection of the shutoff rod 152 of the fuel cut-off bar 150. However, it is possible to prevent the deflection of the shutoff rod 152 of the fuel cutoff rod 150 If it is, it can be deformed into other shapes as well as pipes, pipes and the like. The position where the support rod 160 'is fixed due to the deformed fuel blocking member 150' as shown in FIG. 5 can be deformed. The support rod 160 'is fixed to the inside of the fuel chamber 120 and is fixed to the lower portion of the through hole 123 of the fuel chamber 120. The support rod 160' And supports the end of the stand 150 '. The support rod 160 'has the same function as the support rod 160 fixed to the inside of the above-mentioned hopper 110 but has a different position.

The cooking chamber 170 is formed on the top of the combustion chamber 130 and is formed between the fuel chamber 120 and the heat dissipation chamber 140. The cooking block 170 may directly place the object to be cooked in a space heated by the heat generated by the combustion of the fuel 10, or may cook the food by placing the cooking utensil.
