A motor (8) rotatably supported in the vertical direction, a front cover (9) attached to the front of the motor (8), and a rear card cover attached to the front cover (9); The rear guard (not shown in the figure) is attached to the outer wall of +04, and the front and rear guards (
The blades attached to the rotary shaft (1) of the motor (8) projecting into the interior of the motor (8), the vertical swinging device end attached to the rear m1 of the motor (8), and ) and a cup-shaped rear cover that covers the vertical swing movement (+31 etc.).

The vertical swing device o3) is mounted on a mounting plate 05) fixed to the motor (8), a swing motor (+6) mounted on the mounting plate (+5), and an output shaft of the motor 0. The cam body θ force that is The motor device (4) includes a swinging motor θmari, a cam body attached to the output shaft of the motor (Iil), one end of which is pivotally supported between the cam bodies, and the other end of which is supported between the cam bodies.
7) and a swing link II).

In the above-mentioned conventional structure, the pivot point of the motor (8) by the support (7) is set at a distance H from the front surface of the motor (8), and the width of the support (7) is set to W. An electric fan fi with an elevation angle of s degrees and a depression angle of β degrees.
In order to obtain +, it was necessary to provide a certain distance between the lower surface of the rear cover (14) and the upper surface of the support (7). In this case, the elevation angle and the depression angle β degrees did not take into account the distance between the neck heath (3) and the main body of the fan (6), but in this regard, the shape of the neck piece (3) etc. This can be resolved by doing so. Therefore, in the conventional structure, the above-mentioned dimensions are large.
It is not possible to make the electric fan (1) compact, and in order to increase the angle of vertical swing, it is necessary to increase the above-mentioned dimensions. Although the vertical swing angle can be increased even if the width W of the support (7) is reduced, the motor (8), which is a heavy object, is attached to the tip of the long U-shaped support (7). , which supported the front and rear guards (10) and were insufficient in terms of strength.

(/9 Purpose of the Invention It is an object of the invention to provide an electric fan whose vertical dimensions can be reduced, or whose elevation angle can be increased with the same dimensions.

B) Structure of the Invention The main body of the electric fan is supported by a support member at the lower side of the motor portion of the main body, specifically, at the lower surface of the motor or the lower surface of the rear cover, so as to be rotatable in the vertical direction. The fan plate is configured compactly by reducing the distance between the support member and the main body, and is structured and cut so that the angle in the elevation direction can be increased while keeping the distance between the support member and the main body the same as before. It is.

(-Embodiments of the Invention The present invention will be explained with reference to a first embodiment shown in FIGS. 4 to 6 and a second embodiment shown in FIGS. 7 and 8.

A first example will be explained.

The electric fan has a stand that is placed on the floor, a neck piece that is pivoted to the two ends of the stand so that the angle of elevation can be adjusted, and a left and right neck that is installed in the neck heath. It consists of a vibration motor device ah, and a main body of the electric fan supported rotatably in the left and right directions facing the neck piece. The main body of the electric fan has a bent part (B) at one end with a spindle/L' (to) vertically supported by the neck piece (2).
A substantially U-shaped pivot supported by a support member having a short bent portion at the other end and a long supporting member, and a pivot pivoted between the bent portion @(to) of the support cooperating with each other. A motor (6) with a 4υ mounted on the bottom, a front cover (4) mounted on the front of the motor, a rear garter mounted on the cover 14, and the outer periphery of the rear guard (2). a front guard (not shown) attached to the front and rear guards, a vane decoy attached to the rotating shaft of the motor (6) protruding into the front and rear guards, and a vertical swinger attached to the rear surface of the motor (6). The device i1 [η] and a cup-shaped rear cover decoy that covers the motor [4 and the vertical swing device a←η, etc. a mounting plate (49), a oscillating motor mounted on the mounting plate (49), a cam body extension (1) mounted on the output shaft of the motor (2), one end of which is pivotally supported on the cam body (49); It consists of a swinging link whose other end is pivoted to the tip of the long bent portion (to) of the support tool (2). The left and right oscillating motor device (four forces include a oscillating tanabata fixed in the neckpiece flame, a cam body (58) attached to the output shaft of the motor, and one end connected to the cam body (ffi) and a swing arm whose other end is pivoted to the support.

In this embodiment, in order to clarify the difference between the present invention and the conventional example, the width of the support is W, the distance from the front surface of the motor (2) to the pivot is H, and The fan 6υ with the angle of the tilting direction set as β degrees is the 6th fan.
It is shown in the figure.

Therefore, as is clear from the drawing, the distance between the lower surface of the rear cover and the upper surface of the support is l, and the size relationship with the conventional example is L>
It's J, which makes it more compact. Furthermore, in this embodiment, if the above-mentioned interval l is kept the same as the conventional one, it is clear that the angle in the upward direction and the angle in the downward direction become larger.

Furthermore, since the support C11 is compact, the electric fan clη can be configured compactly from this point as well. In addition, since the bent portion of the support tool (-) is short, it is possible to obtain sufficient strength to support the motor α4 without increasing the width W of the support tool (2). By reducing the width of , the range of the elevation angle and the interval l can be further reduced.

In the first embodiment, the motor (
Although the rear cover υ is directly pivoted, the lower surface of the rear cover υ may be pivoted by the support.

Therefore, the position of the pivot of the fan main body (2) is not particularly limited as long as it is on the lower side of the motor part located below the lower surface of the motor (44). In addition, although the support member - is used as a support member for the main body (to) of the fan M machine, the support member may be the stand (A) or the neck piece. Good too.

In the twelfth embodiment, the present invention is applied to a wall-mounted electric fan that does not particularly require rotation in the upward direction.

The wall-mounted fan (E) consists of a substantially square pyramid-shaped stand attached to the wall (5), and a neck piece (-) that is pivotably supported in the left and right direction by the forked tip of the stand (-). , a left-right oscillating motor device (swing) for driving the neck piece (@) mounted in the stand to oscillate left and right; The main body of the electric fan (81 is a motor with an approximately U-shaped pear-shaft lettering (gQ) formed on the lower surface of the front end, and a front cover attached to the front of the motor (@). , the front cover (the ml rear guard (4) which can be divided into two parts attached to the shoe), and the motor (68
