In winter, if the intake of air into the room due to the exhaust of indoor air by the ventilation fan is taken in from the outside, the temperature of the room will drop significantly, and the adjacent room 31, If it is taken in from 32, the heat load of the heating equipment of the living rooms 31 and 32 will increase. Therefore,
As shown in FIG. 8, if the outdoor air is warmed and supplied, or as shown in FIG. 9, it is supplied to the upper part of the range hood 39 and the heat of the range hood 39 is used to warm the intake air. It is good, however, that the one using the preheater 35 causes an increase in utility costs, and the one supplied to the upper part of the range hood 39 cannot sufficiently warm the cold outdoor air.

Further, if air is taken in from the outside, it is easily affected by a strong outside wind, and stable air supply cannot be performed.
When high air volume ventilation is required, there is a risk of shortage of air supply. Therefore, the present invention provides a residential air supply device capable of sufficiently warming the taken-in air even with heat from a range hood or the like, without causing a decrease in indoor temperature, and capable of performing stable air supply. The purpose is to
