  Currently, garden lights, street lights, and warning lights are not used as household power supplies, but are generated and stored using, for example, a solar power generation device, and the stored power is used for lighting to contribute to energy saving. Attempts have been made.

  As described above, as is clear from Patent Document 1 and Patent Document 2, the configuration of the wind turbine generator is already known. As is apparent from Patent Document 3, attempts have been made to effectively use and use air conditioning outdoor units.

  In addition, home or commercial air conditioners are used throughout the year. In particular, the wind emitted from the outdoor unit for air conditioning has the characteristics of being hot in the summer and cold in the winter, and the wind blown from the outdoor unit. Direct hitting is very unpleasant.

  For this reason, this invention is providing the wind power generator for outdoor units which performs wind power generation using the wind discharge | released from the outdoor unit of an air conditioner.

  Therefore, the present invention relates to a windmill that turns by receiving wind power, a generator connected to the windmill, a power storage device that stores power generated by the power generator, and a converter that outputs power stored by the power storage device In the wind power generation apparatus configured at least by the above, an air inlet and an air outlet are provided, an air passage in which the windmill is disposed is formed between the air inlet and the air outlet, and at least the generator is accommodated. A casing having a storage portion and fixing means for detachably fixing the casing so that the suction port is disposed at a position facing the air outlet of the outdoor unit of the air conditioner.

  Moreover, it is preferable that the casing further accommodates a power storage device and a converter. As a result, an integrated wind power generator can be provided. The wind power generator itself can be made compact.

  The power storage device and the converter may be housed in a power storage / power transmission unit formed separately from the casing. As a result, the portion to be mounted on the outdoor unit can be reduced in weight, so that the mounting property is improved and the power storage / power transmission unit can be installed in an appropriate place, so that space saving can be achieved. In addition, the storage capacity can be improved by making the storage / power transmission unit separate.

  Furthermore, it is desirable that a converter for converting the rotational speed of the windmill is interposed between the windmill and the generator. As a result, the wind power blown out from the outdoor unit and the rotational speed of the generator can be balanced, so that the optimum power generation capacity can be achieved.

  A plurality of air outlets formed in the casing are formed on the outer peripheral edge of the casing, and can change the discharge direction of the air blown out from the outdoor unit. Thereby, for example, when an outdoor unit is installed on the side of the passage, the wind blown from the outdoor unit can be diffused, so that discomfort of passersby can be reduced.

  As described above, by attaching the wind turbine generator for outdoor unit according to the present invention to the outdoor unit for air conditioning, it is possible to generate power from the wind force emitted from the outdoor unit, so that garden lights, street lamps, entrance lights, The power used for alarms, warning lights, etc. can be turned on all night without using a household power supply.

  Moreover, by installing the wind turbine generator for outdoor unit of the present invention on the outdoor unit, the direction of the wind blown out from the outdoor unit can be changed, and the temperature of the blown out air is relaxed (the temperature of hot air in summer) Is reduced, and the cold wind in winter rises), so that discomfort to passersby can be prevented.

  Furthermore, by installing the wind turbine generator for outdoor unit of the present invention on the outdoor unit, a predetermined ventilation resistance is added, so the wind sent from the fan of the outdoor unit is effective in the heat exchanger in the outdoor unit. Therefore, the heat exchange capacity of the outdoor unit heat exchanger is improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  A wind turbine generator 1 for an outdoor unit according to Embodiment 1 of the present invention shown in FIG. 1 has a casing 4 that is mounted on the front surface of an outdoor unit 2 of an air conditioner via a fixing mechanism 3. The casing 4 includes a ventilation portion 40 disposed at a position facing the air outlet 20 of the outdoor unit 2, and a storage portion 41 attached and fixed to the ventilation portion 40. The ventilation section 40 includes a suction port 42 that opens at a position facing the blower outlet 20 of the outdoor unit 2, and a plurality of blower outlets 43 that are formed on a radially outer peripheral edge. An air passage 44 that communicates with the air outlet 43 is defined.

  A propeller-like windmill 5 is disposed in the air passage 44, and a rotating shaft 7 of the windmill 5 is rotatably supported by the casing 4 via a bearing portion 6 and is stored in the storage portion 41. The machine 8 is operated. In the first embodiment, the storage unit 41 stores a power storage device 9 that stores the power generated by the generator 8 and a converter 10 that converts and outputs the power stored in the power storage device 9. The In this embodiment, the converter 10 outputs an AC voltage V1 of 100V and a DC voltage V2 of 12V.

  The power storage device 9 is preferably a light-weight capacitor type power storage device because it is integrally stored in the storage portion 41 of the casing 4, but may be a normal chemical power storage device. In addition, by storing the generator 8, the power storage device 9, and the inverter 10 in the storage unit 41, the wind turbine generator 1 for an outdoor unit can be made compact.

  Furthermore, it is desirable that the fixing mechanism 3 for holding the casing 4 on the front surface of the outdoor unit 2 has an adjuster portion 31 and the width direction can be adjusted depending on the size of the outdoor unit 2. Furthermore, it is desirable to have an adjustment function that can adjust the position in the vertical direction.

  As a result, the wind W blown from the outdoor unit 2 flows into the air passage 44 from the blower outlet 42 to rotate the windmill 5 and blown radially outward from the blower outlet 43. The generator 8 is rotated by the rotation of the windmill 5, and the generated power is stored in the power storage device 9. The electric power stored in the power storage device 9 is converted into a predetermined voltage via the inverter 10 and output. For example, 100V AC voltage V1 and 12V DC voltage V2.

  The outdoor unit wind power generator 1A according to Embodiment 2 of the present invention shown in FIG. 2 divides the storage part 41 of the casing 4 into a power generation part 41A and a power storage / power transmission part 41B, and the power storage / power transmission part 41B. Is a separate body from the casing 4. Accordingly, since only the generator 8 is accommodated in the power generation unit 41A that is integral with the casing 4, the weight of the casing 4 can be reduced, and the casing 4 itself can be made compact. It has the feature that it can do. In the second embodiment, the same portions as those of the first embodiment and the portions having the same effects are denoted by the same reference numerals and the description thereof is omitted.

  The power storage device 9 and the inverter 10 are housed in a power storage / power transmission unit 41 </ b> B formed separately from the casing 4. Accordingly, the power storage / power transmission unit 41B can be installed at any place that does not get in the way. In addition, since the power storage / power transmission unit 41B is separated, the capacity of the power storage device 9 can be increased, and a conventional chemical power storage device such as a battery can be used, so that it can be manufactured at low cost.
