Description

Ventilation fan for ceiling {VENTILATING FAN}

The present invention relates to a ceiling ventilation fan installed on the ceiling of a room to exhaust and supply air to the interior of the room.

Conventionally, as a ceiling ventilation fan installed in the ceiling of a bathroom, for example, there is one disclosed in Japanese Patent Publication No. 2607226.

That is, in FIG. 8, the opening 2a is formed in the ceiling 2 of the bathroom 1, and inside the ceiling 2, the rectangular box-shaped main body 3 has the opening 2a from the bathroom 1 side. It is inserted in and installed. A fan casing 4 is provided inside the main body 3, and a blowing fan 5 is provided inside the fan casing 4. In addition, the fan casing 4 is formed with a suction port 4a which opens downward, and a discharge port 4b that opens laterally.

In the lower part of the ceiling 2, the panel 6 covers the opening part 2a of the ceiling 2, and is provided in the ceiling 2 at predetermined intervals so that air may flow between it. . In this case, the air supply 7 is formed by the portion between the panel 6 and the ceiling 2. In addition, an exhaust port 8 is formed almost at the center of the panel 6, that is, just below the blowing fan 5 and the inlet 4a of the fan casing 4.

At this time, the air supply fan (not shown) is rotated so that the air outside the bathroom 1 is supplied through the air supply 7 into the bathroom 1 (see arrow Q in FIG. 8). As a result, the bathroom 1 is ventilated.

By the way, since the air in the bathroom 1 is high temperature and humidity, the water droplets tend to form on the inner wall surface of the fan casing 4 and the blowing fan 5. However, in the above-described conventional method, since the exhaust port 8 is located directly below the blowing fan 5, the condensation water formed on the inner wall surface of the fan casing 4 or the blowing fan 5 passes through the exhaust port 8 and the bathroom ( 1) It may fall inside. At this time, for example, if the condensation water falls to the body when bathing, the bather feels uncomfortable.

In addition, in this case, since the air in the bathroom 1 is sucked from the substantially vertical direction through the exhaust port 8, when the water droplets adhere to the ceiling 2, for example, the ceiling 2 to which the water droplets adhered is attached. ), It takes a relatively long time to dry.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a ceiling ventilation fan that can quickly dry the ceiling to which the water droplets are attached even when condensation water does not fall into the room, for example, when the water droplets are attached to the ceiling.
