  The first motor section 20 is configured to include an electric motor housed in the first housing section 14 and connected to the fan rotation shaft section 20 a located at the center of the fan section 12.

  The first housing section 14 houses the first motor section 20 connected to the fan rotation shaft section 20 a of the fan section 12 on the back side of the fan section 12. The first housing part 14 is a dome-shaped case, and a convex part 14 a that fits into the concave part 17 of the second housing part 22 is formed on the dome-shaped ceiling part. The first housing part 14 is connected to the housing rotation shaft part 16a, and is rotated by the torque transmitted from the second motor part 16.

  The first angle adjusting unit 34 has a mechanism for changing the position of the convex portion 14a on the back side of the first housing portion 14 with respect to the concave portion 17, and the fan rotation shaft portion 20a and the housing rotation shaft portion 16a It has a function of adjusting the angle θ1 so that the angle formed can move within the range of 180 ± α °.

  Here, since the angle θ1 = 0 ° is a reference angle when the angle between the fan rotation shaft portion 20a and the housing rotation shaft portion 16a is 180 °, the angle θ1 changes within a range of 0 ° ± α. I do.

  The first angle adjustment unit 34 includes a slide unit 37 including a guide unit 33 and a protrusion 35. As shown in FIG. 2, the slide portion 37 has a shape like a horizontally long plate, and has a curved surface along a dome-shaped ceiling portion.

  The guide portion 33 is a protruding member that is guided by the guide long hole portion 30 provided in two rows on the back side of the first housing portion 14 as shown in FIG. The guide slot 30 is formed along both ends of the slide portion 37.

  As shown in FIG. 2, the protrusion 35 is a convex member that can be fitted in a plurality of fitting holes 32 provided on the back side of the first housing portion 14 along the longitudinal direction of the guide elongated hole 30. is there. As shown in FIG. 2, the guide elongate holes 30 in two rows are formed at the center of the slide portion 37.

  The pedestal portion 26 is a base for disposing the electric fan 10 on a floor surface or the like, and has a substantially columnar shape. On the upper surface of the base 26, operation buttons such as a power operation unit, an air volume operation unit, and a timer operation unit of the electric fan 10 are arranged.

  The support shaft portion 24 is a member that extends upward from the pedestal portion 26 and can support the second housing portion 22. As shown in FIG. 1, the support shaft 24 is a rod-shaped member that extends perpendicular to the upper surface of the pedestal 26. The support shaft portion 24 is provided with two support portions in a nested manner, and the height can be adjusted by changing the insertion amount of the two support portions. An inclined portion 23 that extends in an oblique direction is attached to an upper end portion of the support shaft portion 24.

  The second housing portion 22 has a concave portion 17 into which the convex portion 14a on the back side of the first housing portion 14 is fitted, and is connected to a housing rotation shaft portion 16a for rotating the first housing portion 14. The second motor unit 16 is housed.

  The second motor unit 16 is configured to include a geared motor that is an electric motor that reverses (the rotation direction changes in the opposite direction) every time it rotates 180 ° (half rotation). The first housing portion 14 is connected to rotate by the rotation force of the housing rotation shaft portion 16a, which is the rotation shaft of the second motor portion 16. Thereby, as shown in the example of FIG. 2, the first housing 14 operates so as to rotate alternately in the directions of the arrow A and the arrow B.

  A recess 17 is provided on the front side of the second housing portion 22. The concave portion 17 has a depression along the outer shape of the dome-shaped convex portion 14a. The recess 17 is provided on the back side of the first housing part 14 as shown in FIGS.

  The second angle adjuster 19 includes a screw member having a function of adjusting the angle θ2 such that the angle formed between the housing rotation shaft 16a and the support shaft 24 moves within a range of 90 ± β °. Is done. Here, since the reference angle θ2 = 0 ° when the angle between the housing rotation shaft portion 16a and the support shaft portion 24 is 90 °, the angle θ2 changes within a range of 0 ° ± β.

  When the screw member is tightened, the angle θ2 is fixed, and when the screw member is loosened, the second angle adjustment unit 19 can adjust the angle θ2.

  Next, the operation of the electric fan 10 having the above configuration will be described. In the electric fan 10, as shown in FIG. 1B, the first angle adjustment unit 34 sets the angle between the fan rotation shaft 20a and the housing rotation shaft 16a, that is, the angle θ1 to 0 ° ± α. Can be adjusted within the range.

  Further, as shown in FIG. 1A, according to the second angle adjusting section 19, the angle formed between the housing rotation shaft section 16a and the support shaft section 24, that is, the angle θ2 is within the range of 0 ° ± β. Can be adjusted within.

  Since the electric fan 10 has the two-stage adjustment mechanism of the first angle adjustment unit 34 and the second angle adjustment unit 19, various angles can be adjusted and the movable area can be widened. Hereinafter, the width of the movable area of the electric fan 10 will be described with reference to FIGS.

  FIG. 3 is a side view showing a state where the angle of the first angle adjustment unit 34 is changed in the electric fan 10. FIG. 3A is a side view around the fan unit 12 when the angle θ1 of the first angle adjustment unit 34 is 0 ° and the angle θ2 of the second angle adjustment unit 19 is 0 °. FIG. 3B is a side view around the fan unit 12 when the angle θ1 of the first angle adjustment unit 34 is 30 ° and the angle θ2 of the second angle adjustment unit 19 is 0 °.

  In the case of FIG. 3A, the angle θ1 of the first angle adjustment unit 34 is 0 °, that is, the angle formed between the fan rotation shaft 20a and the housing rotation shaft 16a is 180 °. Even when the second housing 16 is rotated by the operation of the second motor 16, there is no change in the direction in which the fan unit 12 sends air.

  On the other hand, in the case of FIG. 3B, the angle θ1 of the first angle adjusting unit 34 is set to 30 °, and the second motor unit 16 operates as it is because the inclined state is maintained. When the first housing part 14 rotates, the wind can be sent up, down, left, and right through 360 ° with the fan part 12 inclined at 30 °. Thereby, the area to be blown can be widened.

  FIG. 4 is a side view of the electric fan 10 when the angle θ1 of the first angle adjusting unit 34 is 30 ° and the angle θ2 of the second angle adjusting unit 19 is 30 ° in the electric fan 10, and the first housing unit. FIGS. 4 (a), 4 (b), and 4 (c) show the state when 14 is rotated.

  In the example of FIG. 4, the angle θ2 of the second angle adjustment unit 19 is set to 30 ° from the state of FIG. 3B so that the second angle adjustment unit 19 faces obliquely upward. Thereby, the wind can be sent to a wide area above FIG.

  FIG. 5 is a side view of the electric fan 10 when the angle θ1 of the first angle adjustment unit 34 is 30 ° and the angle θ2 of the second angle adjustment unit 19 is 50 ° in the electric fan 10, and the first housing unit FIGS. 5 (a), 5 (b) and 5 (c) show the state when 14 is rotated.

  In the example of FIG. 5, by setting the angle θ2 of the second angle adjustment unit 19 to 50 °, which is further increased by 20 ° from the state of FIG. 4, it is possible to send wind to a wider area further above FIG. Can be done.

  FIG. 6 is a side view of the electric fan 10 in the case where the angle θ1 of the first angle adjustment unit 34 is 30 ° and the angle θ2 of the second angle adjustment unit 19 is 70 ° in the electric fan 10, and the first housing unit. FIGS. 6 (a), 6 (b) and 6 (c) show a state in which 14 is rotated.

  In the example of FIG. 6, by setting the angle θ2 of the second angle adjustment unit 19 to 70 °, which is further increased by 20 ° from the state of FIG. 5, the range wider than that of FIG. Can send wind.

  As described above, the first housing portion 14 can be rotated by 360 ° with the fan rotation shaft portion 20a inclined at various angles with respect to the housing rotation shaft portion 16a. The blowing area can be expanded. Further, since the electric fan 10 has the two-stage adjustment mechanism of the first angle adjustment unit 34 and the second angle adjustment unit 19, the fan 10 is set to blow air in various ranges from the ceiling surface to the floor surface. I can do it.
