Abstract

PROBLEM TO BE SOLVED: To reduce time and labor of a construction work by internally providing a quick connection terminal for connecting wires for supplying a power to a motor to wires for supplying a power to an illuminator in the motor. SOLUTION: When a wall switch is operated to be closed, a motor 23 of the ventilating fan for a ceiling is energized from wires via a quick connection terminal 30, and an illuminator is energized via the terminal 30 and the wires. Thus, the motor 23 is rotatably driven at air supplying blades, and the illuminator is lit. When the switch is opened, the motor 23 and the illuminator are interrupted, the motor 23 is then stopped, and the illuminator is turned OFF. Thus, the wires for supplying a power to the motor 23 and the wires for supplying a power to the illuminator are inserted together and connected to the terminal 30 internally provided in the motor 23, and hence the motor 23 and the illuminator can be energized. Accordingly, an operation of the motor 23 and lighting of the illuminator can be controlled without requiring a relay box and its cost can be reduced.

As shown in FIG. 10, a motor 2 having a quick connection terminal 3 provided therein is provided to a motor 2 to which a blower blade 1 is attached and which is driven to rotate. As described in Japanese Patent Application Laid-Open No. 9-159245, the motor 2 has a quick-connecting terminal 3 provided therein. Attachment of the quick-connecting terminal 3 is completed at the same time, and the labor for separately assembling the quick-connecting terminal 3 to the main body frame 4 can be eliminated.

Also, the connection of the quick connection terminal 3 to the motor 2 is performed when the quick connection terminal 3 is assembled to the motor 2, so that it is not necessary at the time of assembling the product of the ceiling ventilation fan. No external parts are required outside the motor 2, and there is no need to equip the body frame 4 with an electrical box for accommodating the quick connection terminal 3.

[0004] That is, according to the present invention, the assembling work and the connecting work of the quick connection terminal 3 at the time of assembling the product of the ceiling fan can be omitted, and the number of necessary parts can be reduced. After the main body frame 4 is attached to the ceiling 5a of the room 5, the electric wire 6a of the power cord 6 for supplying power to the motor 2 is inserted and connected to the quick connection terminal 3. As is well known, the quick connection terminal 3 chucks and holds the connection state by simply inserting the electric wire 6a, and is also called an SL (screwless) terminal.

[0005]

As described above, in the conventional ceiling fan, the electric wire 6a for supplying power to the motor 2 is inserted and connected to the quick connection terminal 3 provided inside the motor 2. It is possible.

However, the room 5 in which the main body frame 4 is attached to the ceiling 5a usually requires lighting equipment, and therefore,
Actually, the electric wire 6 is connected to the quick connection terminal 3 provided inside the motor 2.
a is not directly connected, but one end of the electric wire 7a of the relay cord 7 is connected as shown in FIG. 11 and FIG.
The other end of the electric wire 7a is connected by screwing to a connection terminal 8a existing inside a relay box 8 attached to the back of the ceiling 5a of the room 5, and the connection terminal 8a is connected to the electric wire 6a and the lighting. Connection cord 10 for powering appliance 9
And the electric wire 10a is also connected by screwing.

[0007] The electric wire 6a has a wall switch 11 in the middle of one of the two wires, and a base end (not shown) is connected to a power supply. Therefore, when the user switches the wall switch 11
Is operated, the electric motor 6 of the ceiling ventilation fan is energized from the electric wire 6a through the connection terminal 8a and the electric wire 7a, and the lighting fixture 9 is energized through the connection terminal 8a and the electric wire 10a. The motor 2 operates and the lighting fixture 9 is turned on.

However, in this case, the relay box 8 is specially required to operate the motor 2 of the ceiling ventilation fan and to turn on the lighting fixture 9 as described above, which leads to high cost. Had become. In the relay box 8, the electric wire 7a and the electric wire 6 are connected to the connection terminal 8a.
