2. Description of the Related Art Heretofore, an air supply port has been provided in which a ventilation passage is penetrated through a wall so as to communicate with the inside and outside of a room, and an opening portion of the ventilation passage facing the room is an air outlet. This kind of air supply port takes in outside air into the room by utilizing a pressure difference between the room and the outside. That is, when a ventilation facility or the like is used in a room, the air pressure in the room is lower than the outside air pressure. Therefore, the outside air is introduced into the room by the pressure difference between the room and the outside at that time. In this type of air supply port, due to its structure, air at the outside air temperature flows into the room as it is.

[0003]

On the other hand, in winter, the temperature difference between indoor and outdoor (indoor and outdoor) may exceed 20 ° C. In such a case, if the cold outside air flows into the room as it is from the air supply port, the occupant is given the discomfort of cold. Therefore, the air supply port is often closed,
When the air intake is closed, the amount of fresh outside air that must be supplied to the room is reduced, resulting in poor ventilation and causing dew condensation, mold and chemical sensitivity. The present invention has been devised in view of the above circumstances, and an object of the present invention is to allow outside air to be taken into a room without giving a resident a discomfort, thereby closing an air supply port. It is an object of the present invention to provide an air supply port and an air supply method that can eliminate insufficient ventilation caused by the above.

[0004]

In order to achieve the above object, the present invention provides an air supply port for blowing outside air into a room through an air supply passage communicating between the room and the outside and an air blowing port, wherein the first air A passage, a second air passage, and an air mixing passage, wherein the first air passage and the second air passage are separated from each other, and an upstream end of the first air passage is provided so as to be able to communicate with the air supply passage; An upstream end of the second air passage is provided so as to be able to communicate with the room, and the air mixing passage is connected to each of a downstream end of the first air passage and a downstream end of the second air passage, and the first air passage The air flowing through the first air passage and the air flowing through the second air passage are mixed by the air flowing through the second air passage, and the air outlet is formed by a downstream end of the air mixing passage. It is characterized by being composed That. In the air supply method of the present invention, when blowing outside air into the room through the air supply port, the air in the room is taken into the air supply port by using the flow of the outside air from the outside to the room, and the air is supplied into the air supply port. Create a flow of indoor air. Before the outside air is blown into the room from the air supply port, the flow of the outside air and the flow of the room air are merged in the air supply port to mix the outside air and the room air. It is characterized in that it is made to blow out.

According to the present invention, after the outside air and the room air are mixed in the air supply port, the mixture is blown into the room, and the outside air approaching the room temperature is blown into the room.
