Description

[Detailed description of the invention] The present invention relates to a ventilation fan with an improved structure for adjusting the length of the power cord led out from the outer frame.
The purpose is to provide a ventilation fan which can adjust the lead-out length of a power cord without causing any increase in the number of parts even if the lead-out length of the power cord becomes redundant, and which is generally advantageous in terms of cost.

An embodiment of the present invention will be described below based on the drawings. Reference numeral 1 denotes a rectangular outer frame of the ventilation main body 2, and a decorative frame (not shown) can be freely attached to and detached from the outer frame 1 through flange parts 3 integrally formed on the upper, lower, left, and right sides of the indoor opening of the outer frame 1. It can be attached to. Reference numeral 4 denotes a blower consisting of a capacitor-started motor 5 and a blower fan 6, which is fixed to a support frame 7 disposed within the outer frame 1. Reference numeral 8 denotes a switch device for turning on and off the motor, which is attached to one corner of the indoor side of the outer frame 1, for example, the front surface of the lower left corner;
Reference numeral 9 denotes a plastic capacitor cover which is installed in the lower left corner of the outer frame 1 in the vicinity of the switch device 8, and houses a capacitor 10 for starting the motor inside. A pair of winding protrusions 11 are integrally formed in a substantially inverted L-shape to protrude from each other by a predetermined distance. Note that 9a is a lid fitted to the open end of the capacitor cover 9.

Now, 12 is a power cord, which is connected to the motor 5 via the switch device 8 and the capacitor 10, the tip of which is led out from the outer frame 1 and has a plug 13 attached thereto. . A plastic clip 14 is screwed to the lower part of the flange portion 3 on the left side of the outer frame 1, and is used to clamp the starting end of the power cord 12 extending from the outer frame 1.

By the way, the power cord 12 is led out from the outer frame 1 for a certain length, but the power cord may be too long depending on the installation location of the ventilation fan or the location of the outlet. It is necessary to adjust the lead length of 12.

When adjusting this length, please use the power cord 12.
The length of the lead-out portion from the outer frame 1 is set to a predetermined length depending on the location, and is temporarily fixed with clips 14. In this case, if there is no excess length in the power cord 12 between the clip 14 and the switch device 8, as shown by the solid line in FIG.
The starting end of the power cord 12 can be fixed by strongly tightening the lead-out end of the power cord 12, and if there is an excess length as shown by the two-dot chain line in FIG. The excess length is wound around the winding protrusion 11 of the capacitor cover 9, and then the leading end is fixed with the clip 14.

In this way, in this embodiment, the power cord 12
By winding it around the winding protrusion 11, the length of the winding from the outer frame 1 can be adjusted.

By the way, in the past, a pair of hooks were provided by cutting and bending the metal outer frame as winding protrusions, and the power cord was wound around these hooks. Since there is a risk that the cord may be damaged by the edge of the hook, a vinyl cap is attached to the cord, which increases the number of parts and costs.

On the other hand, according to this embodiment, the winding protrusion 1
1 is integrally formed with the plastic capacitor cover 9, so even if the power cord 12 is directly wound around the winding protrusion 11, there is no risk of damage, and therefore there is no need to cover it with a cap. This reduces the number of parts and reduces costs. Moreover, since the capacitor cover 9 on which the winding protrusion 11 is formed is located near the switch device 8 to which the power cord 12 is connected, the capacitor cover 9 is located near the switch device 8 to which the power cord 12 is connected. The winding protrusion 11 is located at a very convenient location for winding up the excess length of the hanging power cord 12, and the winding protrusion 11 is located at a very convenient location.
Unlike when the switch is located away from the switch device 8, for example in the lower right corner, the excess length does not need to be routed around the outer frame 1 during winding. It is possible to prevent problems such as the exposed portion hitting other components within the outer frame 1.

Note that the winding protrusion is not limited to the pair of L-shaped protrusions as in the above embodiment; for example, a fin-like rectangular protrusion extending in the axial direction of the capacitor cover 9 may be provided and used for winding. It may also be used as a mounting protrusion.

As explained above, the present invention is characterized in that the winding protrusion is integrally molded on the plastic capacitor cover located near the switch device. Not only can the length of the power cord be adjusted by winding it around the switch device, but also the excess length of the power cord can be wound up near the switch device, and the excess length can be used for other purposes. It is possible to prevent defects such as hitting component parts, and there is no risk of damage even if the product is wound directly onto the winding protrusion, so unlike conventional products, there is no need for a cap to prevent scratches, reducing costs. It is possible to provide a ventilation fan that can be used for various purposes.
