<p>The present invention relates to a hot air heater using coal which can uniformly increase indoor temperature by adding a heat-generating case, a blast pipe having a fan formed therein, a lift force-generating wing for inducing smooth transference of heat, and the like to an existing coal heater. To this end, the hot air heater using coal of the present invention includes: a briquette stove (100a); a heat-generating case (10) which is provided along a periphery of an outer room of the coal heater (100a) and forms a space for keeping and transferring the heat generated from the coal heater (100a); a blast pipe (20) which is coupled with an upper side of the heat-generating case (10) and in which a surface corresponding to an upper end of the coal heater (100a) is opened, a fan (30) is provided at one side of the inside thereof, and a cavity is formed through both ends of the lateral direction thereof to enable the inflow and outflow of air; a blast pipe hinge combination member in which the blast pipe (20) is opened or closed from the heat-generating case (10) by combining one side of a lower portion with one side of an upper portion of the heat-generating case (10); and an exhaust pipe (80) which is provided at one side of the heat-generating case (10) to discharge the gas generated from the briquette stove (100a) to the outside.</p> |
