Document Type and Number:
WIPO Patent Application WO/2022/107987
Kind Code:
A1
Abstract:
A pellet stove capable of shortening an initial ignition time is disclosed. A pellet stove according to an embodiment of the present invention comprises: a housing unit having a pellet storage space formed therein and having, mounted on one side thereof, a combustion furnace monitoring window through which a combustion furnace mounted therein can be monitored from the outside; a pellet providing unit mounted inside the housing unit and providing pellets stored in the pellet storage space to the combustion furnace through a tubular transport path; a pellet heating unit mounted adjacent to the tubular transport path and heating the pellets transported through the tubular transport path; the combustion furnace which is mounted inside the housing unit, has a combustion space of a predetermined volume capable of accommodating the pellets received from the pellet providing unit, has a combustion air inlet hole formed on one side or the lower side thereof, and has an ignition device mounted on one side thereof; a combustion air providing unit mounted on one side or inside of the housing unit and supplying air to the combustion air inlet hole of the combustion furnace by sucking air in from the outside; a combustion gas exhaust unit having a structure communicating with an upper space of the combustion furnace and providing a flow path for discharging combustion gas to the outside; a hot air supply pipe for providing heated air to a user by performing heat exchange with the combustion gas exhausted through the combustion gas exhaust unit; a heat transfer unit for preheating the external air sucked into the combustion air providing unit; a combustion air amount adjustment unit for adjusting the amount of the combustion air provided to the combustion furnace from the combustion air providing unit; an exhaust amount control unit for controlling the amount of exhaust discharged by the combustion gas exhaust unit; and a control unit for preheating the combustion air provided from the combustion air providing unit at the time of ignition, and controlling the heat transfer unit, the combustion air amount control unit, and the exhaust amount control unit so as to increase the amount of the combustion air and reduce the amount of exhaust after the ignition is completed.
