[0002]

2. Description of the Related Art Hitherto, various types of house ventilation devices have been developed for introducing air in an underfloor space (that is, underfloor air) into a living room space in order to ventilate a house. For example, as shown in FIGS. 4 and 5, the house ventilation device a is arranged between the wall panels c1 and c2 for partitioning the house and is unitized in a tower shape extending vertically from the floor f to the ceiling k. Become
An air passage e connecting the underfloor space d and the living room space b therein
Is formed.

Further, upper and lower fans g1 and g2 are arranged in the air passage e. For example, in summer, the lower fan g2 is used to suck cool air in the underfloor space d and to blow air from the lower outlet h. In addition to being able to blow out into the living room space b, in the winter season, warm air that tends to stay in the upper portion of the living room space b can be taken in from the air intake i by using the upper fan f, and blown out from the lower air outlet j. .

Further, a damper m for adjusting the wind direction is provided in the air passage e so that the upper and lower fans g1 and g2 can be simultaneously driven by operating to a position shown by a dashed line in FIG. Thus, necessary air circulation can be performed, for example, by mixing the air in the underfloor space d and the air in the upper part of the house space b and supplying the mixed air to the house space b.
