Description

[Detailed Description of the Invention] The present invention relates to an electric fan having a decorative panel on the base.

Conventional electric fans of this type are shown in FIGS. 1 to 3.

Figure 1 is a side view of the base of a conventional electric fan, and Figure 2 is a side view of the base of a conventional electric fan.
The top view of the base shown in the figure, Figure 3 is III-III in Figure 2.
A line cross-sectional view is shown.

In Figures 1 to 3, 1 is the base of the electric fan, 1a is the lower member that covers the base 1 from below, 2 is the decorative panel, 3 is the fan air volume switch, and 4 is the time switch 12. The decorative panel 2 is fixed to the base 1 with mounting screws.The decorative panel 2 is fitted with a convex portion 1C having small holes 1b provided at multiple locations from the inside of the base 1, and a convex portion 1C of the decorative panel 2 that fits into the convex portion 1C. Projection 2
The decorative panel 2 is fastened to the base 1 using the screws 12 via the screws 12, so that the surface side of the decorative panel 2 is not exposed.

As described above, in the conventional electric fan, the mounting bracket 12 is attached to the decorative panel 2 in order to ensure safety when operating the air volume switching switch 3 and the time switch 4, and to improve the aesthetic appearance of the decorative panel 2. Do not expose the surface of the base 1.
Since it is tightened from the inside of the fan, the lower member 1a of the base 1 must be attached after the decorative panel 2 is attached when assembling the electric fan.

In this case, the work of attaching the decorative panel 2 and the lower member 1a to the base 1 is done by laying down the base 1 sideways and attaching it from the bottom of the base. ,
The attached decorative panel 2 may be damaged due to a mistake during the work.

This is not preferable from the aesthetic point of view of the decorative panel 2 as the surface of the product.

Further, although the decorative panel 2 is usually made of plastic material, it may be damaged or deformed by tightening the mounting screws, which is a drawback of the conventional method of fixing the decorative panel 2.

The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional electric fan, and has a protrusion facing outward on the outer periphery of the decorative panel and a recess A that fits into the protrusion. A decorative frame surrounding the outer periphery of the decorative panel, a plurality of pawls provided on the back side of the decorative frame of the decorative panel, and a recess B into which the decorative panel fits through the decorative frame, into which the pawls are inserted. By providing a fan base having a plurality of pawl insertion holes and a pawl holder that engages with the pawls to prevent the decorative panel from being removed, it is possible to prevent the decorative panel from being damaged due to work errors during assembly work. The purpose of this invention is to provide an electric fan that causes fewer scratches on the body.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric fan which is an embodiment of the present invention will be described below with reference to the drawings.

Fig. 4 is a top view of the base of an electric fan that is an embodiment of the present invention, Fig. 5 is a perspective view of the main parts of Fig. 4 before assembly, and Fig. 6 is taken along the VI-VI line of Fig. 4. Cross-sectional view, Figure 7 is VII of Figure 4.
-VII line sectional view is shown.

In Figures 4 to 7, 1 is the base of the electric fan, 1a is the lower member that covers the base 1 from below, 2 is the decorative panel, 3 is the fan air volume switch, and 4 is the time switch. .

The air volume switching switch 3 and the time switch 4 are fixed to the base 1.

5 is an operation hole for the air volume switching switch 3, time switch 4, etc., drilled in the decorative panel 2; 6 is a protrusion provided on the outer periphery of the decorative panel 2 facing outward; 7 is a decorative frame; It has a recess A (7a) that fits into the protrusion 6, and is manufactured in four pieces and attached to the decorative panel 2 so as to surround the outer periphery of the decorative panel 2.

8 are claws, and four of them are provided in the shape of protrusions facing toward the outer circumference of the decorative panel 2 on the back side of the decorative frame 7 of the decorative panel 2.

The decorative panel 2 of this embodiment has a structure in which the protrusion 6 extends to the outer peripheral part of the decorative panel 2 except for the outer peripheral part of the decorative panel 2 corresponding to the surface side of the claw 8, This is an attempt to simplify the structure of the mold when molding the panel 2 from synthetic resin or the like.

Reference numeral 9 denotes a recess B extending in the shape of a groove in the base 1, into which the decorative panel 2 can be fitted via the decorative frame 7.

Reference numeral 10 denotes a pawl insertion opening drilled in the base 1, and four pawls are provided at positions corresponding to the pawls 8 in contact with the recess B (9). 1
It is provided on the base 1 inside the 0.

In assembling the electric fan according to the embodiment of the present invention, as shown in FIG. The claw 8 attaches the decorative panel 2 to which the decorative frame 7 is attached by fitting the recess A (7a) into the protrusion 6 on the outer periphery of the base 1 to which the lower member 1a is attached from the side. When inserted from above so as to fit into the insertion openings 10, the claws 8 engage with the claw receivers 11 of the base 1, preventing removal, and the decorative panel 2 and the decorative frame 7 are inserted into the recess B of the base 1. (9), the decorative panel 2 can be sufficiently fixed to the base 1.

As described above, it is possible to complete the assembly of the fan by fixing the decorative panel 2 to the base 1 from the front side without using screws, etc., so the installation process of the decorative panel 2 can be carried out on the base 1. The installation of the lower member 1a is done in a later process, and there is no need to tilt or fall the base 1 after installing the decorative panel 2, so there is no need to damage the decorative panel 2 due to a work error during the assembly process. You can reduce the possibility of it happening.

In addition, since the decorative panel 2 and the decorative frame 7 fit into the recess B(9) of the base 1 and are sufficiently fixed, the decorative panel 2 can be set in an excellent position on the base 1, and the air volume switching switch 3 , the operation of the time switch 4, etc. will not be hindered.

In addition, the appearance of the decorative panel 2 from the front side is improved aesthetically as the claw insertion slot 10 is hidden by the decorative frame 7, and of course, since no screw fixing is used, the decorative panel 2
Since there are no protrusions on the surface, operational safety is also improved.

As described above, according to the present invention, in the electric fan, the decorative frame surrounds the outer periphery of the decorative panel and has a protrusion facing outward on the outer periphery of the decorative panel and a recess A that fits into the protrusion. a plurality of pawls provided on the back side of the decorative frame of the decorative panel; a recess B into which the decorative panel fits through the decorative frame; a plurality of pawl insertion openings into which the pawls are inserted; Since the base of the fan is equipped with a tab holder that engages with the tab to prevent the decorative panel from being removed, the decorative panel can be fixed to the base from the top when assembling the fan. Since this can be done by inserting the decorative panel, the installation work of the decorative panel can be done in a later process than before, which has the effect of reducing the possibility of damage to the decorative panel due to work errors during fan assembly work. In addition, since no screws or the like are exposed on the surface of the decorative panel, the beauty of the decorative panel is not impaired, and the operational safety of the electric fan is not impaired.
