<p>PURPOSE:To make a single fan perform two functions, one for blowing-off hot air and the other for circulating indoor air by a constitution wherein one fan case, which is formed by dividing a cross-flow fan by a partition plate into two fan case, and the other fan case are formed in forms opposite to each other. CONSTITUTION:A cross-flow fan 9 rotates in the direction indicated with the arrow, resulting in acting for sucking indoor air through a rear surface opening into a combustion chamber 16 so as to mix with the combustion gas produced by burning at a burner 14 in order to pass through a fan case 17 to discharge from the front surface lower opening 4 into a room as hot air. Simultaneously, the cross-flow fan 9 on the side divided by a partition plate 6 acts for sucking the indoor air through a front surface lower opening 5 so as to pass through a fan case 18 in order to discharge from a top surface opening into the room. Because the fan cases 17 and 18 have forms opposite to each other, the air currents in opposite directions are formed by the same fan rotation.</p> |
