Description

[Detailed description of the invention] The present invention relates to a fan that can be disassembled into a fan main body, a main body support pipe, and a pipe support base.

What is shown in FIG. 1 is a conventional floor-type electric fan, and the electric fan 1 includes a fan head 2 comprising a fan motor or the like, a neck piece 3 that supports the head so that it can swing freely, and a neck piece that can be tilted up and down. It consists of a fan frame 4 which is freely pivoted and houses electrical components, a pipe 5 which supports the frame, and a base 6 which supports the pipe unstablely.

The frame body 4 has a structure shown in FIG.

The frame body 4 has a bottom mold made of synthetic resin, and has a bifurcated neckpiece support part 7 formed in its upper part and a cylindrical pipe attachment part 8 formed in its lower part.

A mounting recess 10 for the decorative lamp 9 and a protrusion hole 13 from which a push button 12 of a fan motor control switch 11 protrudes are formed on the front surface of the frame 4.

The heavy head 2 is supported by a pipe 5 via the frame 4, and the frame 4 needs to have sufficient strength.

However, since the recess 10 and the protruding hole 13 are formed in the frame 4, it is necessary to form many reinforcing ribs etc. in order to obtain strength, making the frame structure complicated. Ta.

Furthermore, the formation of the ribs has the disadvantage that many sink marks occur on the surface of the frame, which does not look good and requires the attachment of a decorative plate or the like.

This proposal was made in view of the above points, and will be explained below based on the embodiments shown in FIGS. 3 and 4.

Reference numeral 21 denotes a neckpiece support made of aluminum die-casting, and the support includes a forked portion 22 for pivotally supporting the neckpiece 3, and a cylindrical portion 23 into which the pipe 5 is inserted and fixed.

A connector 24 is fixed to the upper end of the pipe 5, and when the pipe is inserted into the cylindrical part 23, the connector 24 is mechanically connected to a connector 25 fixed to the upper part of the cylindrical part, and electrically connected. conducts to.

The pipe 5 is fixed to the cylindrical portion 23 with a screw 26 screwed into the side surface of the cylindrical portion.

Therefore, the fan head supported by the neck piece 3 is supported by the pipe 5 via the support 21 which has sufficient strength, so that the fan head is supported stably and reliably.

27 is an electrical equipment storage box that covers the support 21 and the upper part of the pipe 5, and the storage box 27 is connected to the support 21 with a screw 28.
Fixed.

A recess 3 for mounting a decorative lamp 29 is provided on the front surface of the storage box 27.
0, an insertion hole 33 for the operation shaft 32 of the timer 31, and a protrusion hole 36 for the operation button 35 of the control switch 34.

37 is a translucent cover that covers the recess 30.

38 is a pipe insertion hole 3 formed on the lower surface of the storage box 27.
9, the guide cylinder 38 has its upper end in contact with the lower part of the cylinder 23, and its lower end is attached to the donut-shaped elastic body 40 attached to the edge of the insertion hole 39.
It is supported within the storage box 27 by being received at.

Since the elastic body 40 is fitted into the annular hanging rib 41 formed at the edge of the insertion hole 39, it will not come out of the storage box 27 even if the cylinder body 38 is mounted and supported.

Since the pipe 5 is guided by the cylindrical body 38, it can be smoothly inserted from the lower part of the storage box 27 into the cylindrical part 23 located at the upper part of the box.

When the pipe 5 is inserted into the cylindrical body 38, the elastic body 4
The inner edge of the pipe 5 is pressed against the outer periphery of the pipe 5.

Therefore, the vibration of the lower part of the storage box with the fixed portion of the storage box 27 to the support body 21 as a fulcrum is efficiently absorbed by the elastic body 40.

Further, since the weight of the electric fan head is not applied to the storage box 27, there is no need to form reinforcing ribs or the like on the inner surface of the storage box 27, and molding can be easily performed.

Reference numeral 42 denotes a back cover that closes the rear opening of the storage box 27, and the back cover 42 is fixed to a mounting portion 43 formed inside the storage box 27 with screws 44.

The mounting portion 43 is formed on the rear surface of the recess 30,
A through hole 45 for the cylindrical body 38 is formed in the mounting portion 43 .

Further, the tip of the screw 14 is pressed against the side surface of the cylindrical body 38 inserted through the insertion hole 45, and the back cover 4 to the storage box 27
Simultaneously with the fixing of 2, the cylindrical body 38 is securely fixed in the storage box 27 with the screw 44.

The head of the screw 26 for fixing the pipe 5 to the cylindrical portion 23 protrudes from a through hole 46 formed in the back cover 42.
The cylindrical portion 23 and the pipe 5 can be attached and detached without attaching and detaching the pipe 5.

As described above, the present invention is to detachably attach a pipe to the cylindrical part of the neckpiece support that supports the head of the fan, cover the support and the upper part of the pipe, and store electrical components such as switches inside. Since the box is fixed to the support, the fan head is supported by the support and the pipe, and the weight of the head is not added to the storage box, simplifying the structure of the storage box. Support is also stable.

In addition, since a pipe guide cylinder is installed between the pipe insertion hole formed in the lower part of the storage box and the lower part of the cylinder part, assembly after disassembly of each part can be carried out smoothly, resulting in great practical effects.
