Abstract

PURPOSE:To make the entire body thin and to make the apperance beautiful, in the ventilating fan, which simultaneously performs air supply and air exhaustion by one fan, by attaching the main body of the fan so that the rotary shaft of a motor becomes approximately vertical with respect to the wall surface of the inside of a room, and contriving the formation of the air supplying and exhausting paths and the like. CONSTITUTION:When an operating switch of the main body of the fan is turned ON in ventilating the air in the room, the fan 3, wherein an air exhausting centrifugal fan 5 on the side of a motor 2 and an air supplying centrifugal fan 4 are combined as a unitary body, is rotated by the motor 2. By this action, the air in the room flows to the fan 5 from an inlet port 7 of a louver 6, and exhausted to the outside of the room through the intermediate part between the main body 1 and a first partitioning part 10 and the part between the main body 1 and a patitioning plate 11. Meanwhile, the outdoor air is supplied into the room through an air supplying path 13, the fan 4, and an air supply port 9 of the louver 6 by the action of the fan 4. In this way, the part of the main body 1 which is protruded into the room can be made compact and thin.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wall-mounted ventilation fan that forcibly takes in and exhausts air at the same time using one fan. The purpose is to make the part that protrudes from the interior wall compact and thin.

Conventionally, as shown in FIG.
2 is installed parallel to the indoor wall surface 103, and an integrated 7-amp 104 for intake and exhaust is connected to the motor 101.
Since it rotates perpendicularly to the rotational axis 102, the protrusion from the indoor wall surface 103 is very large, creating an obstruction and spoiling the aesthetics of the room.

The present invention solves the above-mentioned conventional drawbacks, and an embodiment thereof will be described below based on FIG. 1.

1 is the main body with motor 2 attached, 3 is the rotating shaft 3 of motor 2
A fan that integrates an intake centrifugal cuff 4 and an exhaust centrifugal cuff 6 fixed to the body, 6 is a suction lower for exhausting air with a louver attached to the main body 1, and the exhaust and intake are separated near the outer periphery of the exhaust centrifugal cuff 6. A first partition part 8 and a discharge port 9 for discharging air into the room are provided. Reference numeral 10 denotes a second partition portion on the outer periphery of the intake centrifugal force fan 4 that partitions the exhaust air and the intake air;
Reference numeral 1 designates a partition plate that partitions the exhaust air and intake air within the main body 1, 12 represents an exhaust passage/passage for exhausting indoor air, 13 represents an intake passage for intake of outdoor air, and 14 represents an indoor wall surface.

In the above configuration, when the fan 3 is rotated by the motor 2, the exhaust fan 6 on the opposite side to the motor 2 side causes the fan 3 to rotate.
Indoor air enters from the suction port of the louver 6, flows to the exhaust centrifugal cuff 6, and then flows through the louver 6, the main body 1, and the first partition 10.
It flows through the space of , further flows into the exhaust passage 12 of the main body 1 and is exhausted outdoors, and also flows through the air intake fan 4 on the motor 2 side.
Otherwise, outdoor air enters from the intake passage 13 of the main body 1,
The air flows through the centrifugal cuff for intake 4 and is discharged into the room from the outlet 9 of the louver 6.

As described above, according to the present invention, since the rotation of the fan is parallel to the wall surface, the rotation of the fan is faster than the conventional case where the rotation of the fan is perpendicular to the wall surface.
The part that protrudes into the room can be made compact and thin, making it less of a hindrance than before, and the effect of greatly improving the aesthetics of the room is exhibited.

Claims (1)

[Claims] The main body is mounted so that the axis of one rotation of the motor is almost perpendicular to the indoor wall surface, the centrifugal cuff for exhaust is fixed to the axis of rotation of the motor and sucks in from the side opposite to the motor side, and the centrifugal cuff for intake sucks from the motor side. The centrifugal cuff for exhaust has a fan with an integrated fan and a suction port for exhaust on the front, and a first partition part A is provided near the outer periphery of the centrifugal cuff for exhaust to prevent intake and exhaust from mixing. A louver with an outlet, a second partition part B near the outer periphery of the intake fan to prevent intake air and exhaust air from mixing, and a partition plate to prevent exhaust air and intake air from mixing inside the main body. A wall-mounted ventilation fan comprising: the main body, a louver, a fan, a partition part B, and a partition plate to form an exhaust passage and an intake passage.
