本発明の地熱利用空調装置は、埋設エアー管路１が地中で蛇行状に埋設されているため、省スペースで効率の良い熱交換を行い得る。
しかも、各蛇行部分の水勾配の各下端には夫々ドレン管２が連通し、その水溜部３に排水管４が連通されてドレン水を外部に排出するようにしたから、埋設エアー管路１内の各蛇行部分にドレン水が溜まって閉塞することを確実に防止できる。
さらに、埋設エアー管路１が蛇行状であっても、ドレン管２を利用して内部洗浄が可能となる。即ち、エアー管路１内部を洗浄した洗浄液を各蛇行部分から全てドレン管２を介して、外部に排出できる。 In the geothermal air-conditioning apparatus of the present invention, since the buried air pipe 1 is buried in a meandering manner in the ground, it can perform space-saving and efficient heat exchange.
In addition, the drain pipe 2 communicates with each lower end of the water gradient of each meandering portion, and the drain pipe 4 communicates with the water reservoir 3 to discharge the drain water to the outside. It is possible to reliably prevent drain water from accumulating and blocking in each meandering portion.
Furthermore, even if the buried air pipe 1 has a meandering shape, the inside can be cleaned using the drain pipe 2. That is, the cleaning liquid that cleans the inside of the air pipe 1 can be discharged to the outside through the drain pipe 2 from each meandering portion.

上記構成において、埋設エアー管路１を重力方向に蛇行するように配置し、各蛇行部分の下端に小孔1cを介してドレン管２を連通させた場合には、埋設エアー管路１の埋設のための掘削を縦方向のみ小範囲で行えばよく、埋設エアー管路１の埋設作業を迅速に行い得る。それと共に、ドレン水の排出を円滑に行い得る。
上記構成において、埋設エアー管路１を重力方向に交差させると共に、水勾配を設けて蛇行するように配置した場合には、埋設エアー管路１の埋設のための掘削深さが比較的浅くても、埋設エアー管路の各部と地熱との温度差を略一定とし、効率の良い熱交換を行い得る。 In the above configuration, when the buried air pipe 1 is arranged so as to meander in the direction of gravity and the drain pipe 2 is communicated with the lower end of each meandering portion via the small hole 1c, the buried air pipe 1 is buried. Therefore, the burial operation of the buried air pipe 1 can be performed quickly. At the same time, drain water can be discharged smoothly.
In the above configuration, when the buried air pipe 1 is crossed in the direction of gravity and arranged to meander with a water gradient, the excavation depth for embedding the buried air pipe 1 is relatively shallow. However, the temperature difference between each part of the buried air pipeline and the geothermal heat is made substantially constant, so that efficient heat exchange can be performed.

上記構成において、埋設エアー管路１を直管1aとＵ字管1bとの連結体により構成する場合には、埋設エアー管路１の組立てが容易で且つ部品点数が少なくなり、低コストな装置を提供できる。

上記構成において、水勾配の下流側の接続用直管部６がドレン管２を兼ね、その閉塞手段８の下端位置に小孔1dを設けた場合には、さらに構造が単純で低コストな装置を提供できる。 In the above configuration, when the embedded air pipe 1 is constituted by a connecting body of the straight pipe 1a and the U-shaped pipe 1b, the assembly of the embedded air pipe 1 is easy, the number of parts is reduced, and the cost is reduced. Can provide.
In the above configuration, a pair of parallel connecting straight pipe portions 6 and a plurality of branch pipe portions 7 communicated between them are provided as the buried air pipe 1, and an appropriate position of the connecting straight pipe portion 6 is closed. When closed by 8, the structure of the entire buried air pipe 1 is simplified and the meandering buried air pipe 1 is obtained. Moreover, since each part of the embedment air duct 1 mutually reinforces, it becomes a strong and strong apparatus.
In the above configuration, when the connecting straight pipe portion 6 on the downstream side of the water gradient also serves as the drain pipe 2 and the small hole 1d is provided at the lower end position of the closing means 8, the structure is further simple and the cost is low. Can provide.

上記装置の内部を洗浄する本発明の方法は、埋設エアー管路１内に洗浄液を流入し、排水管４を利用して、その洗浄液を排出するようにしたから、埋設エアー管路１内の洗浄を迅速に且つ完全に行うことができる。   In the method of the present invention for cleaning the inside of the above apparatus, the cleaning liquid flows into the embedded air pipe 1 and the cleaning liquid is discharged using the drain pipe 4. Cleaning can be done quickly and completely.

次に、図面に基づいて本発明の実施の形態につき説明する。
図１は、本発明の第１の実施の形態を示す説明図である。
この例の地熱利用空調装置は、地下16に蛇行状に埋設した埋設エアー管路１を上下方向に形成し、その上流端および下流端を室内11内に連通する。即ち、埋設エアー管路１のエアー入口13が室内11内に位置する。 Next, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is an explanatory view showing a first embodiment of the present invention.
The geothermal air conditioner of this example forms an embedded air pipe 1 embedded in a meandering manner in the basement 16 in the vertical direction, and communicates the upstream end and the downstream end into the room 11. That is, the air inlet 13 of the buried air pipe 1 is located in the room 11.

この例では、埋設エアー管路１に連通するエアー入口13の外周に、入口カバー17が被嵌されている。また、エアー入口13の内部にはフィルタ12が着脱自在に取付けられている。さらに、エアー出口14にはエアー供給装置５が連結され、内部に送風用のファン９が設けられている。そして、そのエアー供給装置５の下流端が室内11内に開口する。
埋設エアー管路１の各蛇行部分の下端は、小孔1cを介してドレン管２に連通する。このドレン管２には水勾配が形成され、その下流端が水溜部３に連通する。そしてこの水溜部３に排水管４の下端が挿入され、その排水管４にポンプ10が設けられ、その排水管４の上端が外部に導かれている。 In this example, an inlet cover 17 is fitted on the outer periphery of the air inlet 13 communicating with the buried air pipeline 1. A filter 12 is detachably attached inside the air inlet 13. Further, an air supply device 5 is connected to the air outlet 14, and a fan 9 for blowing is provided inside. The downstream end of the air supply device 5 opens into the room 11.
The lower end of each meandering portion of the buried air duct 1 communicates with the drain pipe 2 through a small hole 1c. A water gradient is formed in the drain pipe 2 and its downstream end communicates with the water reservoir 3. And the lower end of the drain pipe 4 is inserted in this water reservoir 3, the pump 10 is provided in the drain pipe 4, and the upper end of the drain pipe 4 is led outside.

〔作用〕
エアー供給装置５を駆動することにより、室内11の空気がエアー入口13よりフィルタ12を通過して埋設エアー管路１内に流入し、それが矢印の如く蛇行状に流通する。夏季においては、室温より低温に維持されている地下16と、埋設エアー管路１内の空気とが熱交換され、それが冷風となってエアー出口14からエアー供給装置５を介して室内に吹き出される。そのとき埋設エアー管路１の各蛇行部分の内面には結露が生じ、それらが各小孔1cを介してドレン管２より水溜部３に導かれる。水溜部３には、一例として図示しない液面センサーが設けられ、水溜部３内のドレンが一定レベル以上になるとポンプ10を駆動し、それを外部に排出する。 [Action]
By driving the air supply device 5, the air in the room 11 passes through the filter 12 from the air inlet 13 and flows into the buried air pipe 1, and it circulates in a meandering manner as indicated by an arrow. In summer, the underground 16 maintained at a temperature lower than room temperature and the air in the buried air pipe 1 exchange heat, and the air is cooled and blown into the room through the air supply device 5 from the air outlet 14. Is done. At that time, dew condensation occurs on the inner surface of each meandering portion of the buried air pipe 1, and these are led to the water reservoir 3 from the drain pipe 2 through each small hole 1c. The water reservoir 3 is provided with a liquid level sensor (not shown) as an example, and when the drain in the water reservoir 3 reaches a certain level or more, the pump 10 is driven and discharged to the outside.

この例では、各蛇行部分の下端に小孔1cを介してドレン管２が連通しているので、埋設エアー管路１内に付着するドレンを完全且つ確実に回収し、埋設エアー管路１の内部を乾燥状態に維持することができる。それにより、カビの発生を防止すると共に室内空気の湿気を取り、乾燥した空気を室内に送ることができる。
なお、冬季においては埋設エアー管路１内を流通する空気は地下16で温められる。次いで、図示しない加熱装置で、少しそれを加熱すれば適温の温風を室内11内に導くことができる。 In this example, since the drain pipe 2 communicates with the lower end of each meandering portion through a small hole 1c, the drain adhering in the buried air pipe 1 is completely and reliably collected, and the buried air pipe 1 The inside can be kept dry. Thereby, generation | occurrence | production of mold | fungi can be prevented, the humidity of indoor air can be taken, and dry air can be sent indoors.
In winter, air circulating in the buried air pipe 1 is warmed in the underground 16. Next, if it is heated a little with a heating device (not shown), an appropriate temperature of warm air can be introduced into the room 11.

次に、図２は本発明の第２の実施の形態を示し、この例が前記第１の実施の形態と異なる点は、埋設エアー管路１の蛇行平面が水平面に対し僅かに水勾配をとって、略水平に地中に埋設されていることである。
なお、この例では埋設エアー管路１はドレン管２側が他の部分よりも低く位置されている。また、埋設エアー管路１は多数の直管1aとＵ字管1bとの結合体からなる。そしてドレン管２側に配置されたＵ字管1bは、夫々小孔1cを介してドレン管２に連通する。ドレン管２は、水溜部３側に傾斜するように水勾配が設けられ、ドレン管２内のドレン水を水溜部３に導く。図１および図２において、埋設エアー管路１を地中に埋設するには、地面を所定深さ掘って埋設エアー管路１を配置し、次いで掘り返した土を埋設エアー管路１上に埋め戻せばよい。 Next, FIG. 2 shows a second embodiment of the present invention. This example is different from the first embodiment in that the meandering plane of the buried air pipe 1 has a slight water gradient with respect to the horizontal plane. In other words, it is buried in the ground almost horizontally.
In this example, the buried air pipe 1 is positioned lower on the drain pipe 2 side than the other parts. The buried air pipe 1 is composed of a combination of a large number of straight pipes 1a and U-shaped pipes 1b. The U-shaped tube 1b arranged on the drain tube 2 side communicates with the drain tube 2 through a small hole 1c. The drain pipe 2 is provided with a water gradient so as to be inclined toward the water reservoir 3, and guides drain water in the drain pipe 2 to the water reservoir 3. In FIG. 1 and FIG. 2, in order to embed the buried air pipeline 1 in the ground, the buried air pipeline 1 is arranged by digging the ground to a predetermined depth, and then the dug soil is buried in the buried air pipeline 1. Return it.

次に、図３は本発明の第３の実施の形態を示し、この例はドレン管２をコ字状に形成し、そのドレン管２上に埋設エアー管路１を配置し、夫々のＵ字管1bとドレン管２とを小孔1cを介して連通したものである。
埋設エアー管路１とドレン管２とを予め地上で組み立てておくことにより、装置の取付け作業を効率的に行うことができる。
なお、地中においてドレン管２は排水管４側が低くなるように配置される。 Next, FIG. 3 shows a third embodiment of the present invention. In this example, a drain pipe 2 is formed in a U-shape, an embedded air pipe 1 is arranged on the drain pipe 2, and each U The character tube 1b and the drain tube 2 are communicated through a small hole 1c.
By assembling the buried air pipe 1 and the drain pipe 2 in advance on the ground, the apparatus can be efficiently attached.
In the ground, the drain pipe 2 is disposed so that the drain pipe 4 side is lowered.

次に、図４は本発明の第４の実施の形態を示し、その（Ａ）は全体的説明図であり、（Ｂ）は（Ａ）におけるＢ部拡大図である。
この例は、埋設エアー管路１が一対の接続用直管部６と多数の支管部７および閉塞手段８とからなる。一対の接続用直管部６は互いに平行に配置され、定間隔に並列された支管部７の上下両端が接続用直管部６に連通する。一対の接続用直管部６には千鳥状に閉塞手段８が配置され、それにより埋設エアー管路１内を蛇行状の流路としている。閉塞手段８の最下端には、（Ｂ）の如く小孔1dが夫々設けられている。それにより、接続用直管部６内のドレン水を水溜部３に導くものである。 Next, FIG. 4 shows the 4th Embodiment of this invention, (A) is a general explanatory drawing, (B) is the B section enlarged view in (A).
In this example, the buried air pipe 1 is composed of a pair of straight connecting pipe parts 6, a large number of branch pipe parts 7 and closing means 8.

In this example, the meandering direction of the buried air pipe 1 is changed by 90 degrees through the U-shaped pipe 1b, and the three-dimensional meander structure is shown. It is what makes. The U-shaped tube 1b located on the lower end side communicates with the central small hole 1c and the drain tube 2 as shown in FIG. Thus, by embedding the embedded air pipe 1 three-dimensionally, it is possible to provide a device that saves space and has good heat exchange performance.

次に、本装置の洗浄方法につき述べる。
先ず、入口カバー17およびフィルタ12を取り外して、それらを洗浄すると共に、埋設エアー管路１内に洗浄液を供給して、その洗浄液を埋設エアー管路１内に充満した状態で暫く放置する。それにより埋設エアー管路１内面の汚れやカビが剥離し、洗浄液内にそれが混入する。次にポンプ10を駆動し、埋設エアー管路１内の洗浄液をドレン管２，水溜部３，排水管４を介し外部に流出させる。それにより、埋設エアー管路１内を完全に洗浄し、次いで乾燥させることができる。 Next, a cleaning method of this apparatus will be described.
First, the inlet cover 17 and the filter 12 are removed to clean them, and a cleaning liquid is supplied into the embedded air pipe 1 and left for a while in a state where the cleaning liquid is filled in the embedded air pipe 1. As a result, dirt and mold on the inner surface of the buried air pipe 1 are peeled off and mixed into the cleaning liquid. Next, the pump 10 is driven, and the cleaning liquid in the buried air pipe 1 flows out through the drain pipe 2, the water reservoir 3, and the drain pipe 4. Thereby, the inside of the buried air pipe 1 can be completely cleaned and then dried.
