図１および図２は、本発明の一実施形態を備える温室を示している。なお、図１における左下が前方、同じく右上が後方である。
温室１は、稜線が前後方向を向く切り妻形屋根を有し、かつ建屋の外形を構成すべく枠組みされたサッシ枠と、サッシ枠間に張設された透明ガラス、または透明ビニールシートなどの透光性の部材により構成された建屋躯体２と、温室１内を、培地Ｇを覆う内室Ａとその外側の外室Ｂとを仕切る開閉可能な遮蔽装置３とを備えており、培地Ｇに耕作した複数の畝上に、植物を植設し、温室栽培を行うことができるようになっている。また、建屋躯体２の天井部には、天窓４が開閉可能に設けられ、昼間時などの比較的外気温が高い時間帯に、天窓４を開いて温室１の内部に新鮮な外気を取入れるようにしている。 1 and 2 illustrate a greenhouse comprising an embodiment of the present invention. Note that the lower left in FIG. 1 is the front, and the upper right is the rear.
The greenhouse 1 has a gable-shaped roof whose ridgeline faces in the front-rear direction, and a sash frame that is framed to form the outer shape of the building, and a transparent glass or a transparent vinyl sheet that is stretched between the sash frames. A building housing 2 composed of a translucent member, and an openable / closable shielding device 3 for partitioning the inside of the greenhouse 1 from the inner chamber A covering the medium G and the outer chamber B outside the medium G. Plants can be planted on greenhouses that have been cultivated in the greenhouse and can be grown in greenhouses. In addition, a skylight 4 is provided on the ceiling of the building housing 2 so as to be openable and closable. The skylight 4 is opened and fresh outside air is taken into the greenhouse 1 during a time when the outside air temperature is relatively high such as during the daytime. I am doing so.

建屋躯体２の長手方向一端部の外側には、これに隣接して暖房用の温風発生装置５が配設されている。温風発生装置５は、灯油を燃焼し、その燃焼ガスを温風とする灯油燃焼式のものであり、本体部６と、本体部６の一側部に接続した灯油タンク７と、本体部６の他側部に連結したバーナ８と、本体部６の上部に設けられた初期排気用の煙突９と、煙突９の基部に設けられ、かつ本体部６より発生する燃焼ガスを、煙突９側と温室１側とに選択的に切換えて供給するダンパ１０と、このダンパ１０の温室１側出口に接続され、かつ温室１の内室Ａ内の両側部に分岐して配設された暖房用配管１１と、暖房用配管１１の各分岐部の基部に設けられた強制循環用のファン１２とを備えている。   A warm air generator 5 for heating is disposed on the outside of one end in the longitudinal direction of the building housing 2 so as to be adjacent thereto. The hot air generator 5 is a kerosene combustion type that burns kerosene and uses the combustion gas as hot air, a main body 6, a kerosene tank 7 connected to one side of the main body 6, and a main body The burner 8 connected to the other side of the main body 6, the chimney 9 for initial exhaust provided at the top of the main body 6, and the combustion gas provided at the base of the chimney 9 and generated from the main body 6 Damper 10 that selectively switches between the side of the greenhouse 1 and the side of the greenhouse 1, and the heating that is connected to the outlet of the damper 1 on the side of the greenhouse 1 and that is branched and disposed on both sides of the interior room A of the greenhouse 1 And a forced circulation fan 12 provided at the base of each branch portion of the heating pipe 11.

暖房用配管１１は、本体部６より発生する燃焼ガスが熱媒体として流通することにより、表面が加熱され、その輻射熱により、内室Ａ内を暖房するようにしたもので、図示の例では、内室Ａ内の培地Ｇ上の両側部に１対配設しただけのものとしてあるが、例えば、それらを畝に沿って蛇行するように配設したり、畝内に埋設したり、または３枝以上に分岐して配設したりすることもできる。   The heating pipe 11 is such that the combustion gas generated from the main body 6 circulates as a heat medium, the surface is heated, and the inside of the inner chamber A is heated by the radiant heat. In the illustrated example, One pair is arranged on both sides of the medium G in the inner chamber A. For example, they are arranged so as to meander along the basket, embedded in the basket, or 3 It can also be arranged so as to be branched beyond the branches.

内室Ａを出た１対の暖房用配管１１は、温室１の側端部における外室Ｂ内において立上り、さらに上端部が互いに内方に向かって折曲されている。   The pair of heating pipes 11 exiting the inner chamber A rises in the outer chamber B at the side end of the greenhouse 1 and the upper ends are bent inward from each other.

図２に示すように、遮蔽装置３は、温室１内の両側下部に配設した１対の巻取軸１３、１３に巻き取られた遮蔽カーテン３ａを、案内手段であるガイドローラ１４、１５により、上方に向かった後、互いに内方に向かう正面視倒立Ｌ字状に引き出されるように案内するとともに、各遮蔽カーテン３ａの先端に止着したワイヤ１６を、各遮蔽カーテン３ａが巻かれている巻取軸１３と反対側の内室Ａ内の側部に配設した巻取軸１７により巻き取るようにしてある。
各遮蔽カーテン３ａは、遮熱性の透明なビニールシート、キャンバス地、または布等により形成するのが好ましい。 As shown in FIG. 2, the shielding device 3 is configured to guide the shielding curtain 3 a wound around a pair of winding shafts 13, 13 disposed at both lower portions in the greenhouse 1, as guide rollers 14, 15. Then, the guide curtains are guided so as to be pulled out in an inverted L shape when viewed from the front and then inward, and the shielding curtains 3a are wound around the wires 16 fixed to the tips of the shielding curtains 3a. It winds up with the winding shaft 17 arrange | positioned in the side part in the inner chamber A on the opposite side to the winding shaft 13 which exists.
Each shielding curtain 3a is preferably formed of a heat-shielding transparent vinyl sheet, canvas, cloth or the like.

ワイヤ１６は、案内手段であるガイドローラ１８、１９により、遮蔽カーテン３ａと同様に、巻取軸１７から上方に向かった後、互いに内方に向かう正面視倒立Ｌ字状に引き出されるように案内されている。   As with the shielding curtain 3a, the wire 16 is guided by the guide rollers 18 and 19 serving as guide means so that the wire 16 is pulled out in an inverted L-shape when viewed from the front and then inward from the winding shaft 17. Has been.

左右に隣接するワイヤ１６巻き取り用の巻取軸１７と、遮蔽カーテン３ａ巻き取り用の巻取軸１３とは、巻掛け連動手段である無端ベルト２０が掛け回されることにより、互いに同期して連動されている。   The winding shaft 17 for winding the wire 16 adjacent to the left and right and the winding shaft 13 for winding the shielding curtain 3a are synchronized with each other when the endless belt 20 that is a winding interlocking unit is wound around. Linked.

したがって、いずれか一方の巻取軸１７(または巻取軸１３)を、モータ２１により、予め定めた一方向に回転させることにより、左右の巻取軸１７、１７は同期して回転させられ、両ワイヤ１６を同期して巻き取り、それによって、遮蔽カーテン３ａ、３ａは、左右の巻取軸１３から繰り出されて、図２に示すように、両先端部が温室１内の上部中央において互いに上下に重合また近接する閉止位置まで閉じられる。   Therefore, by rotating one of the winding shafts 17 (or the winding shaft 13) in one predetermined direction by the motor 21, the left and right winding shafts 17 and 17 are rotated synchronously. Both wires 16 are wound up synchronously, whereby the shielding curtains 3a and 3a are unwound from the right and left winding shafts 13 so that both ends are mutually aligned at the upper center in the greenhouse 1 as shown in FIG. It is closed up to the close position where it is superposed and close.

この状態で、内室Ａの両側面と上面とが閉塞される。
なお、内室Ａの前後の端面は、透光性のビニールシート等により常時閉塞しておく。 In this state, both side surfaces and the upper surface of the inner chamber A are closed.
Note that the front and rear end faces of the inner chamber A are always closed with a translucent vinyl sheet or the like.

モータ２１を逆転させて、いずれかの巻取軸１７を、上記と逆の方向に回転させると、上記と逆の作用で、左右の遮蔽カーテン３ａ、３ａは、両巻取軸１３、１３に巻き取られ、遮蔽装置３は開かれる(開いた状態は図示略)。   When the motor 21 is rotated in the reverse direction and any one of the winding shafts 17 is rotated in the direction opposite to the above, the left and right shielding curtains 3a and 3a are moved to both the winding shafts 13 and 13 by the reverse operation. The shield device 3 is wound up (the opened state is not shown).

左右の暖房用配管１１、１１の端末部には、送られてきた燃焼ガスを、外室Ｂ内の上部に導く内向き配管２２と、建屋躯体２の壁面を貫通して、燃焼ガスを温室１外に導く外向き配管２３とに選択的に供給するアクチュエータ付きのダンパ２４が、それぞれ設けられている。   The terminal portions of the left and right heating pipes 11, 11 pass through the inward pipe 22 that guides the sent combustion gas to the upper part of the outer chamber B and the wall surface of the building housing 2, and the combustion gas is sent to the greenhouse. 1 is provided with a damper 24 with an actuator, which is selectively supplied to the outward piping 23 leading outside.

ダンパ２４は、図３に示すように、暖房用配管１１の先端部に接続されたハウジング２４ａと、駆動用サーボモータ(または電磁ソレノイド等)からなるアクチュエータ(または手動操作ハンドル)に連結されるとともに、ハウジング２４ａ内に回動可能に設けられたダンパ板２４ｂとを備えており、後述するような制御装置の作動により、ダンパ板２４ｂが、図３(ａ)に示すように、燃焼ガスを外向き配管２３を介して外部に放出する第１切換位置と、図３(ｂ)に示すように、燃焼ガスを内向き配管２２を介して外室Ｂ内に放出する第２切換位置と、図３(ｃ)に示すように、燃焼ガスを適宜の割合で分配して内向き配管２２と外向き配管２３との両方に供給する中間切換位置とのいずれかに切り換えられる。   As shown in FIG. 3, the damper 24 is coupled to a housing 24 a connected to the tip of the heating pipe 11 and an actuator (or a manual operation handle) including a drive servo motor (or electromagnetic solenoid). And a damper plate 24b rotatably provided in the housing 24a, and the damper plate 24b removes the combustion gas as shown in FIG. FIG. 3B shows a first switching position for releasing the combustion gas into the outer chamber B through the inward piping 22, and a second switching position for discharging the combustion gas into the outer chamber B through the inward piping 22, as shown in FIG. As shown in FIG. 3 (c), it is switched to either an intermediate switching position in which the combustion gas is distributed at an appropriate ratio and supplied to both the inward piping 22 and the outward piping 23.

上記遮蔽装置３におけるモータ２１、ダンパ２４、および温風発生装置５等は、例えば押しボタンスイッチなどの手動操作により個別に駆動されるほか、図４に示すような制御装置２５により自動的に制御されるようにするのが好ましい。   The motor 21, the damper 24, the hot air generator 5 and the like in the shielding device 3 are individually driven by a manual operation such as a push button switch, and are automatically controlled by a control device 25 as shown in FIG. It is preferable to do so.

この制御装置２５は、外気温を測定する外気温センサ２６と、内室Ａ内の温度を測定する室温センサ２７と、日照センサ２８と、上記の遮蔽装置３におけるモータ２１、ダンパ２４、および温風発生装置５にそれぞれ接続され、図５のフローチャートに示すように、日照センサ２８が夜間であることを検知(ST1)し、かつ外気温センサ２６および室温センサ２７が、それぞれについて予め定めた設定温度より低い温度を検知したとき(ST2、ST3)、モータ２１を正転させて、遮蔽装置３を閉じ(ST4)、ダンパ２４を図３(ｂ)に示す第２切換位置に自動的に切り換え(ST5)、かつ温風発生装置５を作動させる(ST6)ようになっている。   The control device 25 includes an outside air temperature sensor 26 that measures the outside air temperature, a room temperature sensor 27 that measures the temperature in the inside room A, a sunshine sensor 28, the motor 21, the damper 24, and the temperature in the shielding device 3 described above. As shown in the flowchart of FIG. 5, each connected to the wind generator 5 detects that the sunshine sensor 28 is at night (ST1), and the outside air temperature sensor 26 and the room temperature sensor 27 are set in advance for each. When a temperature lower than the temperature is detected (ST2, ST3), the motor 21 is rotated forward, the shielding device 3 is closed (ST4), and the damper 24 is automatically switched to the second switching position shown in FIG. (ST5) and the warm air generator 5 is operated (ST6).

この制御装置２５の作動により、遮蔽装置３が閉じられた状態で、温風発生装置５より発生する燃焼ガスが、熱媒体として、暖房用配管１１に供給され、内室Ａ内は、暖房用配管１１の輻射熱により、清浄な状態で暖房され、しかも、暖房用配管１１の先端からから出た燃焼ガスは、ダンパ２４および内向き配管２２を通って、外室Ｂに導入され、この燃焼ガスの余熱により外室Ｂが暖められる。
したがって、内室Ａ内の暖かい空気が、外気によって直接冷却されることがなくなり、暖房効果を高め、ランニングコストを低減することができる。 By the operation of the control device 25, the combustion gas generated from the hot air generator 5 is supplied to the heating pipe 11 as a heat medium in a state where the shielding device 3 is closed, and the inside of the inner chamber A is for heating. The combustion gas is heated in a clean state by the radiant heat of the pipe 11, and the combustion gas emitted from the tip of the heating pipe 11 is introduced into the outer chamber B through the damper 24 and the inward piping 22, and this combustion gas The outer chamber B is warmed by the remaining heat.
Therefore, the warm air in the inner chamber A is not directly cooled by the outside air, and the heating effect can be enhanced and the running cost can be reduced.

外室Ｂ内に導入された燃焼ガスは、天窓４その他の隙間から外部に放出されるが、建屋躯体２の気密性が高い場合には、ダンパ２４の第２切換位置への切り換えに連動して、天窓４を自動的に開くようにするか、または建屋躯体２に設けた排気用ファン(図示略)を作動させるようにするのがよい。   Combustion gas introduced into the outer chamber B is released to the outside through the skylight 4 and other gaps. However, if the airtightness of the building housing 2 is high, the damper 24 is interlocked with switching to the second switching position. The skylight 4 may be automatically opened, or an exhaust fan (not shown) provided in the building housing 2 may be operated.

また、温風発生装置５の作動の初期には、不完全燃焼の燃焼ガスが発生するが、その時期だけ、燃焼ガスがすべて煙突９より外部に排気されるように、ダンパ１０を切り換えておくか、または、不完全燃焼の燃焼ガスもすべて暖房用配管１１に供給し、温風発生装置５の作動の初期だけ、ダンパ２４を第１切換位置へ切り換えておき、暖房用配管１１を通った不完全燃焼の燃焼ガスを、すべて外向き配管２３より外部に排気させるようにするのがよい。   In addition, incomplete combustion gas is generated at the initial stage of the operation of the hot air generator 5, but the damper 10 is switched so that only the combustion gas is exhausted outside from the chimney 9 only at that time. Alternatively, all of the incompletely combusted combustion gas is supplied to the heating pipe 11, and the damper 24 is switched to the first switching position only in the initial stage of the operation of the hot air generator 5, and passes through the heating pipe 11. It is preferable to exhaust all the incomplete combustion combustion gas to the outside through the outward piping 23.

温風発生装置５の安定作動時には、燃焼ガスには、人体に影響のない程度の微量の炭酸ガスが含まれるが、この炭酸ガスは、遮蔽装置３が閉じられていることにより、内室Ｂ内に洩れるおそれは少なく、万一洩れたとしても、植物の生育を助長することはあっても、害となることはない。   During the stable operation of the hot air generator 5, the combustion gas contains a small amount of carbon dioxide gas that does not affect the human body. This carbon dioxide gas is contained in the inner chamber B because the shielding device 3 is closed. There is little risk of leaking into the inside, and even if it leaks, it may promote plant growth, but it will not be harmful.

なお、本発明は、上記の実施形態のみに制限されるものではなく、特許請求の範囲を逸脱しない範囲で、変形した態様での実施が可能である。
例えば、日照センサ２８を省略して実施したり、制御装置２５そのものを省略して、すべて手動で操作することもできる。
温風発生装置５は、燃料ガスや重油を燃焼させて、その燃焼ガスを温風とする型式のものとすることができる(重油燃焼式の場合は、燃焼ガスの浄化装置を並設するのが好ましい)。
また、暖房用配管１１に供給する熱媒体は、温風発生装置５から発生する燃焼ガスに限られるものではなく、例えば、ボイラーから発生する蒸気、その他の高温の気体とすることができる。
さらに、遮蔽装置３における遮蔽カーテン３ａの開閉機構は、どのような構造のものでもよい。 In addition, this invention is not restrict | limited only to said embodiment, Implementation in the modified aspect is possible in the range which does not deviate from a claim.
