Description

  The present invention relates to a fan that can be used in both a fan mode and a circulator mode.

In recent years, fans can operate in a circulator mode that combines both a vertical swing operation and a left and right swing operation, in addition to a normal fan mode based on either a vertical swing operation or a left and right swing operation. In the circulator mode, the room air can be agitated (circulated) to improve the cooling efficiency in summer and the heating efficiency in winter.
For example, Patent Document 1 includes a left and right swing control unit 45 that controls the operation of the first stepping motor 26 and a vertical swing control unit 46 that controls the operation of the second stepping motor 27. Discloses a fan that can be swung in the horizontal direction.

  However, as the vertical and left and right swing angles are widened in order to improve performance, the load applied to the swing motor increases, causing vibrations and wear of the rotating mechanism. There was a problem that abnormal noise was generated.

  Therefore, an object of the present invention is to provide a fan that can be used in both the fan mode and the circulator mode, in which the above-described problems are eliminated.

The gist of the present invention is as follows.

Hereinafter, the electric fan of the present invention will be described in detail by exemplifying an embodiment thereof with reference to the drawings.
Fig.1 (a) is sectional drawing from the back direction of the electric fan which concerns on 1st Embodiment of this invention, represents the up-down direction on the Z-axis, and represents the left-right direction on the Y-axis. The blades face the front in the vertical direction and the front in the left and right direction, that is, the X direction. FIG. 1B is a schematic view of the electric fan according to the first embodiment of the present invention in a state where the blades are directed in the X direction, and FIG. 1C is the electric fan according to the first embodiment of the present invention. FIG. 2 is a schematic view of a state in which the blades face the Z direction.
As shown in FIG. 1A, the electric fan 100 includes a blade 1 (orbit is indicated by a two-dot chain line), a blade motor 2 for rotating the blade 1 around the rotating shaft 3, and the blade 1 up and down. Vertical swing mechanism for swinging in the (vertical) direction, left and right swing mechanism for swinging the blade 1 in the left-right (horizontal) direction, and sliding up and down to adjust the height of the blade 1 The slide pipe 30 includes a support 31 connected to the slide pipe 30, a base 40 connected to the support 31, and an operation panel 50 provided on the base 40 for controlling the operation of the electric fan 100.

The electric fan 100 rotates as a vertical swing mechanism in the vertical direction around the vertical swing motor 12, the drive gear 13 and the driven gear 14 of the vertical swing motor 12, the rotation shaft 15, and the rotation shaft 15. The motor case 16 accommodates the blade motor 2 and the vertical swing motor 12, and the weight 17 (see FIGS. 1B and 1C) disposed behind the motor case 16. When the vertical swing motor 12 rotates, the rotation of the drive gear 13 attached to the vertical swing motor 12 rotates via the driven gear 14 (the driven gear 14 is fixed to the rotating shaft 15 and does not rotate). A motor case 16 attached to the vertical swing motor 12 rotates about the shaft 15. The rotating shaft 15 is pivotally supported by the motor case 16 and is fixed to the support plate 26p in the support plate case 26. When the motor case 16 is rotated 90 degrees clockwise around the rotation shaft 15 from the state of FIG. 1B, the state of FIG. 1C is obtained.
The vertical swing motor 12 is, for example, a stepping motor. When the vertical swing motor 12 is rotated by a certain angle (time), the rotational direction is reversed by reversing the polarity of the applied voltage, thereby enabling the vertical swing operation of the blade 1.

As shown in FIG. 1B, the blade motor 2, the vertical swing motor 12, the rotary shaft 15 and the weight 17 are arranged from the blade 1 side with the blade 1 facing the front in the vertical direction (X direction). They are arranged in this order toward the -X direction. That is, the vertical swing motor 12 is disposed between the blade motor 2 and the rotation shaft 15 on the blade 1 side with respect to the rotation shaft 15. The weight 17 is arranged on the opposite side of the blade 1 with respect to the rotation shaft 15 (−X direction with respect to the rotation shaft 15).
As shown in FIG. 1B, the weight 17 and the position of the weight 17 in the state where the blade 1 faces the front in the vertical direction (X direction) As shown, each member constituting the upper and lower swing parts of the electric fan 100 (the blade 1, the blade guard 1g covering the blade 1, the blade motor 2, the vertical swing motor 12, the drive gear 13, the driven gear 14, and the motor The weight is preferably set in consideration of the weight of the case 16 and the like and the distance from the rotation shaft 15. Thus, by setting the weight and the arrangement position of the weight 17, the load applied to the vertical swing motor 12 is reduced, the occurrence of vibration is suppressed, and the rotation mechanism such as the drive gear 13 and the driven gear 14 is controlled. Generation of abnormal noise due to wear or the like can be prevented. Since the rotation shaft 15 coincides with the rotation shaft 25 for left and right swing operation described later in the X direction, the load applied to the left and right swing motor 22 is reduced by the weight 17 described above, It is also possible to suppress vibration and abnormal noise caused by the left and right swing mechanism.
In the illustrated example, the weight 17 is disposed inside the motor case 16, but may be disposed outside the motor case 16.

  As shown in the side view in FIG. 2, the electric fan 100 can swing about 10 ° downward and about 90 ° upward with respect to the X direction. Note that the angle of the swing operation in the vertical direction is not limited to this angle.

The left and right swing mechanism of the electric fan 100 will be described with reference to FIG.
The electric fan 100 rotates as a left / right swinging mechanism as a left / right swinging motor 22, a drive gear 23 and a driven gear 24 of the left / right swinging motor 22, a rotating shaft 25, and a rotating shaft 25. And a support plate 26p attached to the moving shaft 25. The left and right swing mechanism is disposed in the support plate case 26. When the left / right swing motor 22 rotates, the drive gear 23 attached to the left / right swing motor 22 and the driven gear 24 (fixed to the rotation shaft 25) linked to the drive gear 23 rotate. The support plate 26p attached to the rotation shaft 25 rotates. The support plate 26p and the rotation shaft 25 are pivotally supported by the slide pipe 30 so as to be rotatable.
The left / right swing motor 22 is, for example, a stepping motor, and after rotating at a constant angle (time), the direction of rotation is reversed by reversing the polarity of the applied voltage, thereby enabling the left / right swing operation of the blade 1.

  As shown in FIG. 3, the electric fan 100 can perform a swing operation of about 70 ° to the left and right. Note that the angle of the swing operation in the left-right direction is not limited to this angle.
