Therefore, according to the twelfth embodiment, the operation can be continued with only the electric power from the solar cell panel 27 for an extremely long time without using an external commercial power source.

  A thirteenth embodiment of the present invention will be described with reference to FIG. 14, parts that are the same as or similar to the elements shown in FIG. 1 are given the same reference numerals, and descriptions thereof are omitted. The thirteenth embodiment is a cold / hot air supply device suitable for installation in, for example, a zoo or a park. In the thirteenth embodiment, the underground pipe 1 is buried in an arbitrary place in a zoo or park. At a position above the underground pipe 1, a substantially rod-shaped cylindrical body 2 is projected from the ground. A discharge port 6 that discharges air introduced from the underground pipe 1 and circulated through the cylindrical body 2 to the outside is formed in the approximate center of the cylindrical body 2. In the thirteenth embodiment, a substantially flat roof portion 34 extending in a substantially horizontal direction is disposed above the cylindrical body 2. That is, in the thirteenth embodiment, the upper end portion of the cylindrical body 2 and the hollow portion (not shown) in the roof portion 34 are connected and fixed to each other through the connection portion 35 so that air can flow. Has been. At a plurality of locations on the lower surface of the substantially flat roof portion 34, discharge ports 34a are formed for discharging the air flowing through the hollow portions in the roof portion 34 downward (in the direction in which people are present), respectively. ing. Therefore, in Example 13, the air from the underground pipe 1 is supplied to the substantially flat roof portion 34 via the cylindrical body 2 and the connection portion 35, whereby the substantially flat plate shape is obtained. A comfortable air after heat exchange with the underground heat in the underground pipe 1 is supplied from a plurality of locations on the lower surface of the roof portion 34 to a relatively wide area below the roof portion 34. it can. In the thirteenth embodiment, since the roof portion 34 is provided above the tubular body 2, a person in the vicinity of the tubular body 2 can get wet by the roof portion 34. While preventing, it can receive comfortable cold air or warm air from above.

  A fourteenth embodiment of the present invention will be described with reference to FIG. 15, parts that are the same as or similar to the elements shown in FIG. The embodiment 14 is a cool / warm air supply device suitable for installation in, for example, a dugout of a baseball field (a facility in which a reserved seat for players and managers is provided). As shown in FIG. 15, in the fourteenth embodiment, the upper end portion of the underground pipe 1 embedded in the ground and the lower end portion of the cylindrical body 2 thereabove are connected and fixed so as to allow air flow therebetween. ing. In the fourteenth embodiment, the upper end portion of the cylindrical body 2 extending in the illustrated vertical direction is connected to the end portion of the substantially rod-shaped extension flow path portion 36 extending in the illustrated horizontal direction so that air can flow. Yes. The air sent from the cylindrical body 2 into the extended flow path portion 36 is discharged obliquely downward in the figure from discharge ports 36 a formed at a plurality of locations on the side surface of the extended flow path portion 36. In the fourteenth embodiment, the extended flow path portion 36 is for extending the flow path through which the air in the cylindrical body 2 flows to a place away from the cylindrical body 2.

  While the embodiments and examples of the present invention have been described above, the present invention is not limited to those described as the embodiments and examples, and various modifications and changes can be made. For example, in the above-described embodiment and each example, the case where the cold / hot air supply device according to the present invention is mainly installed outdoors has been described. However, the present invention can be applied to any place in a building, for example, in a kitchen in a building. It can be placed in various places such as in a dressing room. Further, as described above, the underground pipe and the cylindrical body in the present invention extend not only in a straight line with respect to the ground surface or the floor surface but also in a substantially horizontal direction with respect to the ground surface or the floor surface. Various shapes such as a substantially L-shape including a part, a substantially U-shape that is partially curved, and a shape in which a plurality of portions are bent are possible. Further, as described above, the underground pipe and the cylindrical body in the present invention are not limited to those having a circular cross section but also include those having a polygonal cross section. Moreover, in each said Example, the case where the said underground pipe 1 and the said cylindrical body 2 were mutually corresponded in the horizontal surface (it overlapped in the horizontal surface) was mainly shown (the part which is not partly shown). However, in the present invention, the underground pipe 1 and the cylindrical body 2 do not coincide with each other in the horizontal plane (not overlap in the horizontal plane), and a predetermined connection portion (for example, for connection extending in the horizontal direction) This includes the case where they are connected and fixed so that air can flow through each other via a pipe or the like.
