Abstract

PURPOSE:To improve a snow-melting effect with a small device by dividing an outside air passage up and down by means of a partition and providing a heating body on the lower part to heat the fresh air directly and indirectly. CONSTITUTION:The fresh air is taken in from an air intake 4, passes through an upper duct 6 and an opening 8 and, then, after passing through a heating body 9, introduced into a room duct 12 through a lower duct 7. As this time, the partition 5 is heated by the heating body 9, while the temperature inside the upper duct 6 is also raised. Accordingly, the temperature of the fresh air passing through the upper duct 6 is raised and the snow floating in the fresh air is introduced to the partition 5 side by a guide plate 10, coming a contact with, or close to, the partition 5, and the melting of snow is accelerated. After that, the fresh air passes through the heating body 9 provided on the lower duct 7, further raising its temperature and melting the snow. The device is made light since it can be formed only by an upper and a lower duct 6, 7.

In the figure, 4 is a fresh outside air intake, 5 is a partition wall for dividing the upper duct 6 and lower duct 7, and 9 is the above-mentioned partition l! in the lower duct 7. 5 is a heating element provided at a position capable of heating the partition wall 5, that is, in close contact with the partition wall 5. ] 0 guides the fresh outside air passing through the upper duct 6 to the partition wall 5 side, and separates the fresh outside air from the snow. This is a guide plate for contacting or approaching 5. In addition, 8 is the upper duct 6
and an opening that communicates with the lower tact 7; ] 1 is a drain plate provided at the end of the partition wall 5 on the side of the opening 8 to prevent ice from melting snow on the surface of the partition wall 5 from penetrating into the interior; .
