(First embodiment)
Hereinafter, the hydraulic drive device in 1st Embodiment of this invention is demonstrated based on FIG. 1 thru | or FIG. FIG. 1 is an example in which the hydraulic drive device of the present invention is applied to a blower unit 10, and is a schematic diagram showing the overall configuration of the blower unit 10. 2 and 3 are explanatory views showing an application example of the blower unit 10.

  As shown in FIG. 1, a blower unit 10 that is a hydraulic drive device of the present embodiment is installed in the middle of a water supply pipe 1. The blower unit 10 includes a water turbine 12, a blower 17 as power means, and a housing 11, and is configured to rotate the blower 17 provided outside the water passage 2 indirectly by the rotational force of the water turbine 12. is doing.

  First, the housing 11 is formed of a resin material, and a partition plate 11 a is formed inside to partition the inside and outside of the water passage 2. The upstream end and the downstream end of the water passage 2 are connected to the water supply pipe 1. Yes. A suction port 11b is formed outside the water passage 2. The upstream end and the water supply pipe 1 and the downstream end and the water supply pipe 1 are sealed by an airtight member such as an O-ring (not shown).

  The water turbine 12 is disposed in the water passage 2 formed in the casing 11 so as to rotate by flowing water energy, and the blower 17 is disposed above the partition plate 11a, that is, outside the water passage 2 and substantially coaxial with the water turbine 12.

First, when water flows in the water supply pipe 1, the water wheel 12 is rotated by the flowing water energy. Then, when the first magnet 14a is rotated by the rotation of the water wheel 12, an attractive or repulsive magnetic force acts on the second magnet 14b on the blower 17 side, and the rotational force is transmitted to the blower 17 side indirectly and in a non-contact manner. Thus, the blower 17 can rotate.

  Thereby, the air blower 17 can be rotated by substantially the same rotation without reducing the rotational force of the water turbine 12. Therefore, compared with the apparatus which converts the rotational force of the water wheel 12 into electric energy, stores electric power in the battery, and drives the blower motor using the stored electric power as a power source, the parts for converting the rotational force into electric energy can be reduced. .

  It should be noted that a nozzle is provided in the water passage 2, and the water flow ejected from the nozzle is vigorously applied to the water turbine 12, or a swirl flow is formed in the water flowing in the water passage 2 so as to vigorously strike the water turbine 12.

Can be rotated.

  Therefore, compared with the apparatus which converts the rotational force of the water wheel 12 into electric energy, stores electric power in the battery, and drives the blower motor using the stored electric power as a power source, the parts for converting the rotational force into electric energy can be reduced. . In addition, since it is not necessary to drive the blower 17 with a power source, the component cost of the blower 17 can be reduced.

  Moreover, the non-powered fragrance generator 20 can be easily configured by combining the blower unit 10 and the fragrance 20a as the fragrance generator 20. Moreover, the deodorizer 20 of a non-power supply can be easily comprised by combining the deodorizer 21a and the ventilation unit 10 instead of the fragrance | flavor 20a.

  Further, by installing the blower unit 10 in a storage space in the sink 4 or the cabinet 4 of the wash basin, a ventilation fan for ventilating the sink 4 or the cabinet 4 of the wash stand by the blower 17 can be easily configured without a power source.
