  As shown in FIGS. 11, 12, and 13, the opened upper end 50 of the motor cover row 47 enters the opening 44 below the motor cover 24, and the upper side of the motor cover row 47 and the lower side of the motor cover 24 are over. When the motor cover 24 is rotated in the vertical direction, there is a gap L1 having a predetermined distance between the outer surface 52 of the motor cover row 47 and the inner surface 54 of the lower end 53 of the opening 44 below the motor cover 24. Thus, the motor cover 24 rotates.

  The gap L1 is provided with a gap and an interval, for example, about 1 to 3 mm, such that a foreign substance such as a finger does not enter or is difficult to enter.

  The motor cover 24 has a horizontal cylindrical shape, and is continuously opened by connecting a lower opening 44 and an opening 46 on one side 45. A plurality of openings 46 are provided on the outer circumference of the motor 25 when viewed from the front. Thereby, when the blade 19 rotates, a part of air is sucked into the motor cover 24 from the gap L <b> 1, and an airflow flowing into the blade 19 through the opening 46 of the one side surface 45 is generated. With this air flow, the temperature rise of the motor 25 in the motor cover 24 can be reduced. Further, since this air flow enters the motor cover 24 along the outer surface of the motor cover row 47, the air flow flows along the inner surface of the motor cover 24 and flows so as to cover the motor unit 22, so that the temperature of the motor 25 rises. Can be reduced efficiently.

  Opposite sides of the blades 19 of the motor cover row 47 and the motor cover 24 have an arc shape 56, and the center of the arc shape 56 is a pivotal support that is reciprocally rotated in the vertical direction in the blowing direction by the vertical swinging means. 34 and the shaft support 35 are located concentrically.

  As shown in FIGS. 5 and 6, in the above configuration, when the crank 39 is rotated by the stepping motor 38, it is uniquely determined by the relationship between the pivot 16, the length of the link 40, and the pitch fixed by the screws of the crank 39. In the fixed angle range determined by the following, the link 40 causes the motor holder 23 to rotate within the fixed cover 14 about the pivot 16 of the motor holder 23 as the center of rotation, and the air blowing means and the vertical swinging means are moved horizontally. That is, it is reciprocated in the left-right direction. The upper strut portion 5 is moved up and down by the left and right swinging means, but is fixed without swinging and swinging back and forth, that is, horizontal swing, that is, horizontal swing, vertical swing, that is, vertical swing. I do not.

  When the crank 42 is rotated by the stepping motor 41, the motor holder 23 is placed in a certain angle range that is uniquely determined by the relationship between the length of the fixing portion 33 and the link 43 and the pitch fixed by the screw of the crank 42 or the like. The motor holder 23 rotates about a shaft support 34 and a shaft support 35 that rotatably connect a hole at the tip of the character body 32 and a hole provided in the rotation support portion 30 of the motor front plate 27. And the blade | wing part 18, the motor part 22, the motor holder 23, and the motor cover 24 which are a ventilation means are rotated to the orthogonal | vertical direction, ie, an up-down direction.

  The basic configuration of the electric fan 1 is as described above. As shown in FIGS. 14 and 15, the feature of the present embodiment is composed of a control unit 66 fixed to the motor unit 22 and an electric wire part 57 extending from the control unit 66 to the left and right swinging means. The control unit 66 extends from the control unit 66 to the left and right swinging means through the vicinity of the rotation center portion in which the motor unit 22 rotates in the vertical direction.

  Specifically, the pivot center is a shaft support 34 and a shaft support 35. When the motor part 22 rotates in the vertical direction, the part that rotates in the vertical direction including the motor part 22 is the center of the opening opened in the upper part of the U-shaped body 32 of the motor holder 23 that does not rotate in the vertical direction, That is, it rotates in the vertical direction about the shaft support 34 and the shaft support 35. An electric wire portion 57 that connects a control portion 66 fixed to the motor portion 22 that rotates in the vertical direction and a stepping motor 38 that is a left and right swinging means that does not rotate in the vertical direction is a shaft support 34 that is the center of rotation in the vertical direction. And routed around the vicinity of the shaft support 35.

  As a result, when the motor unit 22 swings in the vertical direction, the positional relationship between the vertical swing unit and the control unit 66 is close or far, but between the vertical swing unit and the vertical swing center. , And the distance between the control unit 66 and the vertical swing rotation center portion is kept constant, so that the electric wire portion 57 connecting the vertical swing means passing through the vicinity of the vertical swing rotation center portion and the control unit 66 is Since the amount of displacement in the length direction is reduced, there is an effect that the stress applied to the electric wire portion 57 when the motor portion 22 swings in the vertical direction is reduced and the risk of disconnection is reduced.

  Moreover, the electric wire part 57 extended from the control part 66 to the left-right swing rotation means has a length that can follow the wall surface of the space through which the electric wire part 57 passes.

  Specifically, the wall surface of the space through which the electric wire portion 57 passes is the space between the motor cover inner 26 and the motor holder 23 or between the motor cover inner 26 and the motor cover front 36 at a position above the motor holder 23. It is the inner wall of the space. The electric wire part 57 is separated from the control part 66 and is routed along the inner wall of the space between the motor cover inner 26 and the motor cover front 36 or the motor holder 23.

  Thereby, since the movement of the electric wire part 57 can be suppressed without using a fixing means because the electric wire part 57 follows the wall surface of space, the stress which generate | occur | produces by fixing the electric wire part 57 can be avoided, and disconnection There is an effect that fear is reduced.

  Further, the electric wire part 57 extending from the control unit 66 to the left and right swing rotation means is directed in a direction opposite to the direction of the left and right swing means immediately after coming out of the control unit 66 and extends from the left and right swing means to the control unit 66. 57 may be configured to extend so as to extend in the direction opposite to the direction of the control unit 66 immediately after coming out of the left and right swing means.

  As a result, the wire portion 57 does not extend in a straight line toward the target direction to be connected, and the wire portion 57 can be bent by extending the wire portion 57 by making a detour. It is possible to reduce the stress on the part and to reduce the risk of disconnection.

  The motor holder 23 includes a flat plate 31 having a horizontal surface and a U-shaped body 32 extending upward from the left and right sides of the plate 31, and the motor section 22 rotates in the vertical direction on the U-shaped body 32. A rotation center is provided. The left and right swing means includes a stepping motor 38 fixed to the upper surface on the back side of the plate 31, a crank 39 rotated by the stepping motor 38, and a link 40 attached to the crank 39. The electric wire part 57 extends from the upper part on one side in the left-right direction of the control part 66 downward to the upper surface of the plate 31 along the motor part 22, and extends from there to the stepping motor 38 along the upper surface of the plate 31. May be.

  Thereby, since the electric wire part 57 extends along the motor part 22, the electric wire part 57 comes along the vicinity of the vertical swing center part, and the amount of displacement in the length direction when rotating in the vertical direction is reduced. When the motor unit 22 swings in the vertical direction, the stress applied to the electric wire unit 57 is reduced, and the risk of disconnection is reduced.

  In addition, the electric wire portion 57 extends downward from the upper portion on one side in the left-right direction of the control portion 66 along the motor 25 that is the motor portion 22, and further passes between the motor 25 and the plate 31. It may be configured to extend to the upper surface on the other side in the left-right direction and then extend to the stepping motor 38 along the upper surface on the other side in the left-right direction of the plate 31.

  Thereby, since the electric wire part 57 extends between the motor 25 and the plate 31 and extends to the other side of the upper surface of the plate 31 in the left-right direction, the length of the electric wire part 57 is increased, and the bending radius when the electric wire part 57 is bent is increased. Since the ratio of the moving amount with respect to the length of the electric wire portion 57 when moving in the length direction is reduced, the stress on the bent portion of the electric wire portion 57 can be reduced, and the risk of disconnection is reduced. There is an effect.

  Further, the control unit 66 may be fixed to the back side of the motor unit 22 and the electric wire unit 57 may be extended from the control unit 66 so as to be pressed to the vicinity of the rotation center portion on the front side.

  Specifically, the control unit 66 is attached to the motor cover inner rear portion 26a, and the electric wire portion 57 extends so as to be pressed against the motor cover inner front portion 26b in order to pass near the rotation center portion.

  Thereby, by setting it as the structure extended so that the electric wire part 57 may be pressed against the vicinity of the rotation center part of the front side from the control part 66, sufficient slack was produced in the space which the electric wire part 57 passes, and by the slack Since the electric wire part 57 fits between the motor 25 and the plate 31 and the movement of the electric wire part 57 can be suppressed without using a cable tie or a notch for fixing, the electric wire part 57 is fixed. The generated stress can be avoided, and the risk of disconnection is reduced.

  In the present invention, the electric wire portion 57 moves in accordance with the vertical rotation of the motor portion 22 although the movement amount is small as compared with the case where it does not pass through the vicinity of the vertical rotation center portion. Therefore, in order to ensure a sufficient length with respect to the moving amount of the electric wire part 57, the length from the binding band 68 to the control part 66 is ensured by using the electric wire part fixing member 67 and the binding band 68.

  The electric fan according to the present invention includes a base, a support column extending from the support, a motor holder provided on the support column so as to be rotatable in the left-right direction, and a left-right direction for rotating the motor holder in the left-right direction. A swinging means, a motor part provided on the motor holder so as to be rotatable in the vertical direction, a vertical swinging means for rotating the motor part in the vertical direction, and a drive shaft extending from the motor part to the front side A blade portion fixed to the motor portion, a control portion fixed to the motor portion, and an electric wire portion extending from the control portion to the left and right swinging means. The electric wire portion is vertically moved from the control portion to the motor portion. It extends to the left and right swinging means via the vicinity of the rotation center portion that rotates in the direction, and can further improve the durability of the electric wire portion.

  That is, the electric wire portion extends from the control portion to the left and right swing means via the vicinity of the rotation center portion where the motor portion rotates in the vertical direction, so when swinging up and down, the left and right swing means and the control means However, the distance between the control means and the rotation center and the distance between the rotation center and the left and right swinging means are kept constant. As a result, the electric wire portion extending from the control portion to the left and right swing means via the vicinity of the rotation center portion has a small amount of displacement in the length direction, and the stress applied to the electric wire portion when swinging up and down is small.
