  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
As shown in FIGS. 1, 2, 3, and 4, the ceiling fan 1 includes a support column 2, a motor unit 3, a blade unit 4, a control unit 5, a discharge product generating unit 6, and a case unit 7. And a lower cover portion 8.

  The column part 2 has a hollow rod shape, and has a suspended part 9 that can be engaged with the ceiling in the upper part, and the motor part 3 is fixed to the lower part.

  The motor unit 3 is an outer rotor motor, and includes a stator core 10, a stator winding 11, a magnet 12, and a rotor 13. The rotor 13 is rotatably provided in the motor unit 3. That is, when the motor unit 3 is driven, the rotor 13 rotates.

  The blade portion 4 includes a substantially rectangular plate-like blade portion 4a and a blade fixing portion 4b on the base side of the blade portion 4a. This blade fixing portion 4 b is fixed to the rotor 13.

  As shown in FIG. 2, the control unit 5 is provided at an upper portion of the motor unit 3, and includes a control board holding unit 14, a control case unit 15, and a control board unit 16 provided in the control case unit 15. It is configured.

  The control board unit 16 is electrically connected to the motor unit 3, the discharge product generation means 6, and a power supply wire (not shown) extending from the ceiling. The control board unit 16 controls the motor unit 3 and the discharge product generation means 6.

  The case portion 7 has a cylindrical side surface and is provided with an opening 20 that is a square opening on the side surface.

  The lower cover portion 8 has a substantially bowl shape and covers the lower portion of the blade fixing portion 4b.

  The discharge product generating unit 6 is provided above the motor unit 3 in the case unit 7 and includes a discharge product generating unit 17, a discharge product generating unit control unit 18, and a communication unit 19.

  The discharge product generation unit 17 includes a needle-like discharge electrode 21 and a counter electrode 22 disposed to face the discharge electrode 21, and a Peltier element 23 disposed as a cooling unit that cools the discharge electrode 21. Become.

  The discharge product generating means controller 18 applies a high voltage (-5 KV in this embodiment) between the counter electrode 22 and the discharge electrode 21 and applies a voltage of about 0.75 V to 2.8 V to the Peltier element 23. To do. In this embodiment, the discharge electrode 21 side is set to a low temperature. Cooling at the discharge electrode 21 portion causes condensation to generate charged fine particle water that is a discharge product. The hydroxyl radicals in the charged fine particle water react with the odor, and oxidize it to decompose the odor.

  A hydroxyl radical is a radical that reacts with a hydroxy group (hydroxyl group), and since this radical usually has only one electron that should be rotating in orbit in pairs, it is very unstable electrically. In order to take away the missing electrons from the surrounding atoms and molecules, the oxidizing power is very strong, and the odor is decomposed and removed by this oxidizing action. The discharge product generating means 6 is not limited to the above charged fine particle water, but may be any one that generates a discharge product for sterilization and deodorization.

  The feature of the present embodiment is that the discharge product generating means 6 is provided in the case part 7 above the blade part 4, and the discharge product generating means 6 is provided by the opening 20 provided on the side surface of the case part 7. 7 It is a point that communicates with the outside.

  Specifically, when the blade portion 4 is viewed from below and rotated in the clockwise direction, the blade portion 4a is inclined, so that an airflow flowing from the ceiling to the floor is generated. Due to this air flow, an induced air flow that flows downward along the side surface of the case portion 7 is generated on the side surface near the opening 20 of the case portion 7 above the blade portion 4. The air in the communication part 19 is attracted to the outside of the case part 7 through the opening part 20 of the case part 7 by this induced airflow. In addition, since the case part 7 above the opening part 20 and the case part 7 below the opening part 20 are formed on the same surface, the induced airflow that flows downward along the side surface of the case part 7 is generated. It is easy to flow, and the air in the communication part 19 is easily attracted to the outside of the case part 7 through the opening 20 of the case part 7.

  With such a configuration, the discharge product generated by the discharge product generating means 6 is discharged from the opening 20 of the case part 7 to the outside of the case part 7 through the communication part 19.

  That is, since the discharge product generation part 17 is not exposed outside the case part, the design can be improved.

  Further, a communication part 19 extending in the horizontal direction from the opening 20 is provided between the discharge product generating means 6 and the opening 20, and an upper surface hole which is a hole in the uppermost surface on the innermost side of the communication part 19. 24. The discharge electrode 21 of the discharge product generating means 6 is located above the upper surface hole.

  That is, the discharge product is generated from the discharge electrode 21 of the discharge product generating means 6, and passes through the communication part 19 from the upper surface hole provided immediately below the discharge electrode 21, and communicates with the communication part 19. 7 is released to the outside of the case portion 7 from the opening portion 20 on the side surface of 7.

  Such a configuration prevents dust from reaching the discharge electrode 21 of the discharge product generating means 6 even when dust enters from the external space, and stable discharge from the discharge product generating means 6. Can be obtained.

  Further, the discharge electrode 21 has a configuration extending downward. By adopting such a configuration, it is possible to suppress the adhesion of dust from the space above the discharge product generation means 6 in the case portion 7 and to obtain a stable discharge from the discharge product generation means 6. .

  In addition, the blade portion 4 is configured to rotate in both the clockwise direction and the counterclockwise direction when viewed from below.

  When the opening 20 on the side surface of the case portion 7 is provided above the blade portion 4, the discharge product discharged from the opening 20 is diffused throughout the space as follows.

  First, when the blade part 4 is rotated clockwise as viewed from below, an opening on the side surface of the case part 7 above the blade part 4 is caused by an induced airflow that flows downward when the blade part 4 rotates. It is attracted to the lower part of the blade part 4 from the part 20, and is diffused in the entire space by the wind generated by the rotation of the blade part 4.

  Next, when the blade portion 4 rotates counterclockwise when viewed from below, the side surface of the case portion 7 located above the blade portion 4 is caused by the induced airflow that flows upward when the blade portion 4 rotates. Is attracted to the upper portion of the blade portion 4 from the opening portion 20 and diffused throughout the space by the wind generated by the rotation of the blade portion 4.

  If the opening part 20 is provided below the blade part 4, when the blade part 4 rotates counterclockwise when viewed from below, the discharge product is charged fine particle water. Compared to the case of being provided above 4, it is considered that it is attracted upward by the blade part 4 and is less likely to be diffused throughout the space. That is, it is considered that the discharge product is easily moved downward by gravity. Here, in the blade portion 4 that rotates counterclockwise when viewed from below, the opening portion 20 is provided below the blade portion 4 as compared to the case where the opening portion 20 is provided above the blade portion 4. The moving distance upwards becomes longer. Therefore, it is thought that it becomes difficult to be diffused in the whole space.

  On the other hand, when the opening 20 is provided above the blade 4, the discharge product discharged from the opening 20 on the side surface of the case portion 7 is diffused throughout the space regardless of the rotation of the blade. Can be made.

As described above, the present invention provides a support column that can be engaged with the ceiling, a motor unit provided at a lower portion of the support column, a blade unit that is rotated by the motor unit, and a control unit that controls the rotation of the motor unit. And a case part covering at least a part of the motor part and the control part, and a discharge product generation means, the discharge product generation means is provided in the case part above the blade part, The discharge product generating means communicates with the outside of the case portion through an opening provided on a side surface of the case portion. That is, the discharge product generating means is provided in the case portion, and the design can be further improved.
Therefore, it is expected to play an active role as a ceiling fan for home use and office use.
