  The motor cover portion 9 is made of resin, has a bowl shape with an open bottom surface, and has openings on the front surface and the back surface. The motor cover portion 9 is fixed to the motor fixing plate portion 6, and includes the motor portion 7, the motor fixing plate portion 6, the rotating motor portion 10, the rotating motor substrate fixing portion 11, the metal balance weight 12, and a rotation described later. The dynamic motor substrate 14 and the rod 15 are covered. When viewed from the side of the electric fan, the motor cover portion 9 is inclined downward as it goes from the front to the rear.

  The rotation means 4 includes a rotation motor unit 10, a rod unit 15, and a rotation motor substrate unit 14.

  The rotation motor unit 10 is fixed to the motor fixing plate unit 6, has a rotation motor substrate unit 14 in the upper part, and has a shaft (not shown) for rotating the rod part 15 in the lower part. .

  The rod portion 15 is fixed to the clutch portion 16 interlocking with the shaft extending from the rotation motor portion 10 and the support column portion 2.

  The rotation motor substrate portion 14 is provided on the upper portion of the rotation motor portion 10 and is fixed to the rotation motor substrate fixing portion 11. The rotation motor substrate portion 14 includes a rotation motor substrate portion (not shown) and a rotation motor substrate case portion 14a. The rotation motor substrate case portion 14a has a box shape, includes a rotation motor substrate portion therein, and has a plurality of holes 14b on the upper surface. When the rotation motor substrate portion in the rotation motor substrate case portion 14a generates heat, warmed air is emitted from a large number of holes 14b on the upper surface, so that the temperature rise in the rotation motor substrate case portion 14a is suppressed. Is done.

  The rotation motor substrate fixing portion 11 is provided behind the motor portion 7 and is fixed to the motor fixing plate portion so as to sandwich the front side of the rotation motor substrate portion 14.

  A feature of the present embodiment is that a metallic balance weight 12 that covers at least the upper surface of the rotating motor substrate portion 14 is provided.

  That is, by covering at least the upper surface of the rotating motor substrate portion 14 with the metallic balance weight 12, heat generation from the rotating motor substrate portion 14 due to long-term use is blocked, and heat generation and deterioration of the motor cover portion 9 are prevented. Can be suppressed. As a result, the safety can be further improved.

  The balance weight 12 includes an upper surface portion 12a that covers the upper surface of the rotating motor substrate portion 14, and side surface portions 12b that extend downward from both ends of the upper surface portion 12a.

  Specifically, the upper surface portion 12a has a substantially rectangular flat plate shape having a horizontal surface, and includes a side surface portion 12b extending downward from both left and right sides of the upper surface portion 12a. The side surface portion 12b has a substantially rectangular flat plate shape having a vertical surface. That is, when viewed from the rear of the electric fan, the vertical cross-sectional shape is a U-shape with the lower part opened.

  Accordingly, when the rotation motor unit 10 and the rotation motor substrate unit 14 generate heat due to long-term use, the upper and side surfaces of the rotation motor unit 10 and the rotation motor substrate unit 14 are covered with the metallic balance weight 12. By covering, heat generation is blocked. Furthermore, since the front part and the rear part of the metallic balance weight 12 are opened, it is possible to suppress the heat generation of the rotation motor unit 10 and the rotation motor substrate unit 14 by creating an air vent.

  The thickness of the upper surface portion 12a of the balance weight 12 is larger than the thickness of the side surface portion 12b. More specifically, the thickness of the upper surface portion 12a is the maximum at the front and gradually decreases toward the rear, so that the balance can be maintained without affecting the shape of the motor cover portion in a limited space. Is. Further, when the rotation motor unit 10 and the rotation motor substrate unit 14 generate heat due to long-term use, the rotation motor substrate fixing unit 11 that fixes the rotation motor substrate unit 14 may also generate heat. . In this case, the distance to the metal balance weight is such that the rotation motor substrate fixing portion 11 that fixes the rotation motor substrate portion 14 is more metal than the rotation motor substrate portion 14. Since it is close to the weight 12, it has a thickness in the vicinity of the rotating motor substrate fixing portion 11, that is, in front of the metal balance weight 12. As a result, the safety can be further improved.

  Moreover, the flange part 12c extended outward is provided in the lower end side of the side part 12b. Thus, by providing the flange portion 12c, when the metallic balance weight 12 is screwed to the motor fixing plate portion 6, it can be mounted without having to support it by hand, and efficient assembly can be achieved. It is.

  Further, the metal balance weight 12 is not directly attached to the rotation motor unit 10 or the rotation motor substrate unit 14, but the rotation motor unit 10, the rotation motor substrate unit 14, and the metal balance weight 12. By making a space between them, heat conduction to the metal balance weight 12 can be suppressed. As a result, the safety can be further improved.

  As shown in FIGS. 4 and 5, the motor cover portion 9 has a front opening 17 on the front surface and a rear opening 18 on the back surface, and the side surface portion 12 b of the balance weight is located on the left and right sides of the motor cover portion. It is provided.

  That is, when the blade portion 8 is rotated by the motor portion 7, air is sucked into the motor cover portion 9 from the opening on the lower surface of the motor cover portion 9 and the rear opening 18. A part of the sucked air passes through the balance weight 12. That is, it flows between the balance weight 12 and the rotating motor substrate portion 14, and passes from the front opening 17 of the motor cover portion 9 to the motor cover above the rotating motor substrate fixing portion 11 and around the motor portion 7. It blows out of part 9. Accordingly, the motor cover portion 9 has a front opening 17 on the front surface and a rear opening 18 on the back surface, thereby creating a wind vent, and the rotation motor portion 10 and the rotation motor substrate portion that are used for a long time. The heat generation and deterioration of the motor cover 9 caused by the heat generation of 14 can be suppressed. Since the front, back, and bottom surfaces of the metal balance weight 12 that are not covered with the air vents are formed, heat generation can be suppressed without blocking the metal balance weight 12. As a result, the safety can be further improved.

  Further, when the blade portion 8 rotates, air is sucked into the motor cover portion 9 from the opening on the lower surface of the motor cover portion 9 and the rear opening 18, and blows out of the motor cover portion 9 from the front opening 17 of the motor cover portion 9. . The flow of the wind in the motor cover portion 9 mainly flows from the rear to the front in the electric fan. When the balance weight 12 is viewed from the rear of the electric fan, the vertical cross-sectional shape is a U-shape opened at the lower side and extends in the front-rear direction of the electric fan. That is, since the wind flowing in the motor cover portion 9 flows along the surfaces of the upper surface portion 12a and the side surface portion 12b of the balance weight 12, the balance weight 12 is efficiently cooled.
