この考案は、自動車の室内暖房用ヒータの内外
気切換装置にヒータユニツトとを結合するエアダ
クトに関する。[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an air duct that connects a heater unit to an inside/outside air switching device of a heater for indoor heating of an automobile.

As shown in FIG. 1, a typical heater air duct 1 has an inside/outside air switching device 2 and a heater unit 3 connected to each end, and a bellows 1a in the middle so that these can be connected properly. Pressure force is generated in both directions. The inside/outside air switching device 2 has a damper that switches between introducing outside air from the cowl top and circulating inside air inside the room.

Conventionally, during heavy rain, rainwater that has entered through the cowl top portion of the internal/external air switching device may leak from the connection between the internal/external air switching device and the air duct, and wet the area near the feet of the passenger seat. If this part is completely sealed, this situation will not occur, but it has the drawback of increasing costs.

This invention is a concave portion for a water reservoir formed in the lower bottom surface near the opening end suitable for the inside/outside air switching device in an air duct that connects the inside/outside air switching device of the heater and the heater unit. A concave portion whose wall surface on the heater unit side is inclined toward the heater unit is formed integrally with the air duct.

As shown in FIG. 2, the air duct 11 has a recess 11 for a water reservoir in the lower bottom surface near the opening end 11b connected to the outer periphery of the outlet opening of the inside/outside air switching device 2.
c is formed. As shown in FIG. 3, the wall surface 11d of the water reservoir recess 11c on the side of the heater unit is inclined toward the heater unit side, and the water accumulated in the recess 11c is directly transferred to the recess 11.
At the same time, the water evaporates inside the air duct 11 and is blown upward along the wall surface by the air flowing inside the air duct 11 from the inside/outside air switching device 2 toward the heater unit 3, becoming minute water droplets inside the air duct 11 and inside the heater unit 3. Evaporate.

According to this invention, even if rainwater enters from the cowl top of the inside/outside air switching device, the water will collect in the recess of the air duct and will not leak to the outside. In addition, since the accumulated rainwater is evaporated by the air passing through the air duct, there is no need to connect a drain hose to the recess to drain the water. The purpose can be achieved at low cost with a simple structure.
