Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of a switch operating lever for a wall-mounted electric fan.

[Conventional technology]

Figures 5 to 7 are drawings showing a conventional electric fan disclosed in, for example, Japanese Utility Model Publication No. 39-5688. A flexible wire with a built-in inner wire 3a for remote control; one end of the inner wire 3a is fixed to the other end of the operating shaft 1a, and the other end is connected to the oscillation mechanism of the electric fan, and the inner wire 3a is connected to the swinging mechanism of the electric fan. It moves by 4a
1 is a mounting plate, which is formed by bending support plates 4b and 4c back and forth, which loosely fit and support the operating shaft 1a so as to be slidable back and forth. A, A _a are protrusions formed on both sides of the support plate 4b, 5a is a coil portion formed in the center, and two springs with both ends extended in the same direction, connecting one end of each extended end so that they are parallel. A nearly U-shaped butterfly spring formed by
The protruding portions A and _Aa of b are inserted and locked, and the middle side of the U-shape engages with locking grooves 6a and 6b formed on the outer periphery of the operating shaft 1a.
The two end portions of the butterfly spring 5a are always in contact with the flat surface of the mounting plate 4a, and the middle side portion presses the operating shaft 1a.

The conventional electric fan is constructed as described above, and when the inner wire 3a is pushed as shown in FIG. 7, one side of the butterfly spring 5a fits into the locking groove 6a and locks the operating shaft 1a. There is. In this state, when the knob 1b is operated and the operating shaft 1a is pulled, the inner wire 3a is pulled, and the portion of the butterfly spring 5a that is engaged with the operating shaft 1a is released from the locking groove 6a and is inserted into the locking groove 6b. The depressed operating shaft 1a is the inner wire 3a
Locks when pulled. Swing control is performed by repeating this operation.

[Problem that the invention attempts to solve]

Since the conventional electric fan described above has a structure in which the knob 1b is pulled linearly, it is necessary to install and operate the fan so that the outlet of the flexible wire 2a and the axis of the operating shaft 1a are on the same line. If there is, and they are not on the same line, the flexible wire 2a
A stiffness occurs between the inner wire 3a, the shaft of the operating knob 1b, and the bearing portions of the support plates 4b and 4c of the mounting plate 4a, increasing resistance. Therefore, the operation of the knob 1b becomes difficult and the operability deteriorates. For this reason, the mounting plate 4 is
In addition to preventing deformation of the flexible wire 2a, when fixing the flexible wire 2a to the mounting plate 4a, adjust the height and angle of the mounting plate 4a so that the axis of the operating knob 1b and the axis of the inner wire 3a are the same. It needs to be firmly fixed, and it must be pulled along the axis so that it does not curl during operation. Further, when attaching the operating shaft 1a, there was a problem that workability was poor, such as having to hold down the butterfly spring 5a.

This idea was made to solve these problems, and it is a wall-mounted fan that not only operates smoothly even when the control lever is tilted and is easy to install, but also has convenient lever operation. The purpose is to obtain.

[Means for solving problems]

A blower section consisting of an electric motor, blades, and a guard and having a swinging mechanism; a base section that rotatably supports the blower section and is hung on a wall; A wall-mounted electric fan having an oscillation control switch connected via a tube and a speed control switch provided in the base for switching the speed of the electric motor,
An endless swing operating lever suspended from the swing control switch and an endless speed operating lever suspended from the speed control switch are provided, and both levers have the same protrusion from the base. A wall fan characterized by being formed in a U-shape at the center and on the same plane.

[Effect]

In operation of this wall fan, by pulling downward the speed control lever 31 protruding from the lower part of the base part hung on the wall, the switching sliding piece 29 engaged with the lever slides. The speed display plate 30 rotates, its notch is displayed in the display hole 36, and the electric motor 2 rotates to blow air.

By pulling the swing operation lever 26 downward, the sliding piece 25 engaged with it slides downward and is locked, and the flexible tube 33 is pulled through the spring 32 to operate the swing mechanism of the blower section 1. The blower unit 1 swings its head from side to side.

〔Example〕

Figures 1 to 4 show an embodiment of this invention, and in the figure, 1 is a blower section with a swing mechanism, an electric motor 2, a blade 3, and a pair of guards covering the front and rear of the blade 3. It is formed from 4. 5 is a handle provided at the lower part of the guard 4 to move the blower section 1; 6 is a base; and 16 is a stand forming this base 6, which is hung on a mounting bracket 20 attached to a wall 8. It is fixed with a fixing screw 10. The blower section 1 is rotatably supported by a neck piece 18 which is pivotally supported by a neck pin 17. Reference numeral 19 denotes a reinforcing plate provided on the back side of the stand, and 20 a mounting bracket for securing and fixing the reinforcing plate with fixing screws 10, which are fixed to the wall 8 with screws 21. Reference numeral 22 designates a swing control switch provided in the stand 16, which has a locking mechanism and is provided with a sliding piece 25 having an engagement hole 23 formed at one end and an engagement portion 24 formed at the other end. It is being Reference numeral 26 is a metal oscillating operating lever that is slidable up and down, with one end engaged with the engaging portion 24 and the other end projected externally from an opening 39 provided in the base. It is formed into a U-shape and is bent forward with a predetermined curvature. 2
Reference numeral 7 denotes a switch for controlling the electric motor 2, which is provided with a switching sliding piece 29 that slides up and down to switch contacts and has an engaging portion 28 formed at the end thereof, and a speed display plate that rotates when switching. 30 are provided. Reference numeral 31 denotes a metal switch operating lever which is formed so that one end thereof is engaged with the engaging portion 28 of this switch and the other end is formed to be slidable up and down with the other end protruding from the base portion 6 and the opening 39. It is formed in a U-shape with the same center as the swing operating lever 26, is bent forward with a predetermined curvature, and is formed on the same plane as the swing operating lever 26. . A spring 32 has one end engaged with an engagement hole 23 provided in the sliding piece 25 of the swing control switch 22, and the other end is connected to the swing mechanism of the blower section 1 via a flexible tube 33. ing. 34 is a timer provided in the stand 16, and 35 is a front panel attached to the stand 16, which is provided with a plurality of display holes 36, in which the speed display board 30 of the switch 27 is displayed.
