BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ventilator which is inserted into an opening provided in a room wall and discharges dirty air in the room to the outside.

[0002]

2. Description of the Related Art Conventionally, this type of ventilator is generally shown in FIG.
And it was comprised as shown in FIG. That is, a cylindrical shape is inserted into the opening 102 formed in the room wall 101 from the room 103 side, and the opening 102 is formed at the end of the room 103 side.
Inside a main body 105 provided with a flange portion 104 abutting on a peripheral edge of the room 103 side, a blower 108 including an electric motor 107 to which a blade 106 is fixed is provided. The flange 104 of the main body 105 has a cord lead-in hole 110 for drawing a power supply wire 109 disposed in the room wall 101 into the room 103, and a power supply cord of the blower 108 in the power supply wire 109 drawn in from the cord lead-in hole 110. A connection terminal 112 for connecting 111 is provided.
The flange portion 104 houses electrical components such as a capacitor 113 connected to the blower 108 and a crimp terminal 114 for connecting the power cord 111. A louver 115 that covers the flange portion 104 and guides air to the blades 106 is mounted on the room 103 side of the main body 105. In addition, a drain hole 116 for discharging dew condensation water and the like generated inside the power cable 107 to the outside is provided in a jacket of the power supply cable 107.

The installation of the ventilation device in the above configuration has been performed as follows. When the drainage hole 116 is positioned below so that the dew condensation water accumulated inside the motor 107 is drained well in advance, a hole 117 communicating with the cord drawing hole 110 is opened in the chamber wall 101, The power supply wire 109 wired in the room wall 101 is drawn into the room 103 through the hole 117, and
The installation work is completed by pulling the main body 105 into the opening 102 of the room wall 101, connecting the power supply wire 109 to the connection terminal 112, and finally installing the louver 115 while pulling the main body 105 forward from the cord insertion hole 110 of FIG. .

[0004]

In such a conventional ventilating apparatus, the positional relationship between the cord drawing hole 110 of the flange portion 104 of the main body 105 and the drainage hole 116 of the electric motor 107, that is, the angle, is fixed. In this state, for example, as shown by a two-dot chain line in FIG.
In the case where an obstacle such as the body edge 118 is provided directly below the body 2, a hole 117 is opened in the room wall 101 and a through hole 119 is also provided in the body edge 118 to draw the power supply wire 109 into the room 103. Since it must be provided, there is a problem that workability is reduced.

The present invention solves the above-mentioned problem. In order to ensure the drainage of dew condensation accumulated inside the motor when there is an obstacle such as a rim behind the cord lead-in hole when installing a ventilation device. Further, it is an object of the present invention to provide a ventilation device that can easily draw out a power supply wire disposed in a room wall to a room side without performing a troublesome operation such as opening a hole through which the power supply wire passes through the obstacle. The purpose is.

[0006]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and has a cylindrical portion inserted into an opening provided in a chamber wall, the flange being in contact with a peripheral edge of the opening on the indoor side. A main body having a cord lead-in hole for drawing a power supply wire wired in the chamber wall to the inside of the room at the flange portion, a blower disposed inside the main body, and provided at the flange portion, A connection portion for connecting the power supply wire to a power supply cord of the blower, and a flange portion of the main body,
The ventilator has a configuration in which at least one cord lead-in portion is provided at a position different from the cord lead-in hole so that the power supply wire can be led indoors.

[0007]

According to the present invention, when the ventilator is installed, if there is an obstacle such as a rim behind the chamber wall where the cord lead-in hole of the flange is located, the ventilator is installed in a place where there is no obstacle. A hole is opened in the room wall behind the located cord lead-in portion, and the power supply wire disposed in the room wall can be easily drawn into the room from the cord lead-in portion.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

As shown in the figure, a cylindrical shape is inserted into the opening 2 formed in the room wall 1 from the room 3 side, and the end of the room 3 is in contact with the peripheral edge of the opening 2 on the room 3 side. Flange part 4
Inside the main body 5 provided with a blower, a blower 9 composed of an electric motor 8 having a blade 6 fixed to the front and a drain hole 7 provided at a lower end is disposed. The flange portion 4 of the main body 5 is provided with a cord lead-in hole 11 for leading the power supply wire 10 disposed in the room wall 1 into the room 3, and the three cord lead-in portions 13 closed by the thin portions 12. However, it is provided at a position different from the cord drawing hole 11. Further, the flange portion 4 is provided with a connection terminal 15 for connecting the power supply cord 14 of the blower 9 to the power supply wire 10 drawn from the cord lead-in hole 11. The flange 4 and the main body 5 are mounted on the indoor 3 side to cover the flange 4,
Electrical components such as a capacitor 16 connected to the blower 9 and a crimp terminal 17 for connecting the power cord 14 are accommodated in a space between the louver 18 for guiding the air to the blade 6.

In the above configuration, when the ventilator is installed, when the drainage hole 7 is positioned below so that the condensed water accumulated in the electric motor 8 can be drained well, the cord lead-in hole of the flange portion 4 is formed. If there is an obstacle such as a rim 19 shown by a two-dot chain line in the figure behind the room wall 1 where the locator 11 is located, a hole for drawing the power supply wire 10 into the room 3 is provided in the rim 19. A hole 20 is opened in the chamber wall 1 behind the cord lead-in portion 13 provided at a place where the waist edge 19 is not located, and the thin portion 12 of the cord lead-in portion 13 is broken without performing a troublesome work of opening the cord lead-in portion 13. In addition, the power supply wire 10 can be easily drawn into the room 3 through the cord drawing portion 13.

In the practical example, the thin portion 12 is provided in the cord lead-in portion 13 so as to be broken when the cord lead-in portion 13 is used.
There may be no pores, and there is no difference in the operation and effect.

[0012]

As is apparent from the above embodiments, according to the present invention, when installing the ventilation device, there is an obstacle such as a rim at the rear of the chamber wall where the cord lead-in hole of the flange portion is located. In this case, the power cable can be easily drawn into the room from the cord lead-in section where no obstacle is located, without having to perform the troublesome work of opening the hole for the power cable through this obstacle. Can be provided.
