Fig. 2 is a top view of the same. You. An integrated air conditioner 20 with the cooler 1 on the upper side and the heater 2 on the lower side is installed on the floor behind the seat, and the inlet 3a of the cooler 1 is on the underside of the cooler 1. In addition, the outlet 3 is provided on the upper surface of the cooler 1. At the end of the duct 4 that is connected to the cooler 1 and reaches both sides of the seat, two outlets 7 are provided on each of the left and right sides. The outlet 7 is provided with a grill for adjusting the direction of the outlet and a shutter for closing the outlet. Further, the inlet 5 for the heater 2 is provided on both sides of the heater 2, and the outlet 6 is provided on the front of the heater 2.
一方、 座席 3 0 には シー ト 8 の前面か ら後方に向 っ て シー ト 8 内を貫通 し、 さ ら に背当て 9 の下端から上端に 至る接続 した通風孔 1 0 が設け られてい る。 こ の通風孔 1 0 内に は、 シー ト 8 の後部に相当する 部分に小形の ク ロ ス フ ロ ーフ ァ ン 1 1 が配設さ れて いる。 ま た運転者の 尻、 背中に対する暖房効果を高める手段 と して、 シー ト 8 前部の通風孔開口部付近に小形ヒ ータ 1 2 が配設さ れ てい る。 On the other hand, the seat 30 is provided with a ventilation hole 10 which penetrates through the seat 8 from the front to the rear of the seat 8 and extends from the lower end to the upper end of the backrest 9. . This ventilation hole In 10, a small cross-flow fan 11 is provided in a portion corresponding to the rear of the sheet 8. As a means to enhance the heating effect on the driver's buttocks and back, a small heater 12 is provided near the opening of the ventilation hole at the front of the seat 8.
上記空調装置および座席によ つて構成される空調 シ ス テ ム を利用 したキ ャ ビ ン内冷房の場合、 ク ー ラ 1 の上面 か ら吹き 出 した冷風は座席の背後か ら運転者の頭上を通 り 、 キ ャ ビ ン 1 3 の前部で下降 した後、 足元を通って ヒ ータ 2 の間か ら ク ーラ 1 の下面の吸い込み口 3 a に吸い 込ま れる経路でキ ャ ビ ン 1 3 内を冷却する。 こ の と き前 記冷風の一部は座席の シー ト 8 前面に設け られた開口部 8 a か ら シー ト 8 内に入り 、 ク ロ ス フ ロ ーフ ァ ン 1 1 に よ っ て背当て 9 内に送 られ、 シー ト 8 と背当て 9 とを冷 却 した上、 背当て 9 上端か らキ ャ ビ ン 1 3 内に排出さ れ る。 ま た、 ク ー ラ 1 の左右両側に接続さ れたダク ト 4 は、 その先端が座席の左右にま で延びて いて、 ダ ク ト 4 先端部に設け られた吹き岀 しロ 7 の う ち、 左右各 1 個の 吹き 出 し口 7 a か ら吹き出 した冷風は、 運転者の下肢を 冷却 した後、 ク ー ラ 1 の下面の吸い込み口 3 a に吸い込 ま れる。  In the case of air conditioning in a cabin that uses an air conditioning system composed of the above air conditioners and seats, the cool air blown out from the upper surface of cooler 1 is above the driver from behind the seats. After descending at the front of the cabin 13, the cabin is drawn into the suction port 3 a on the lower surface of the cooler 1 from between the heaters 2 through the feet. 1 Cool down the inside of the unit. At this time, a part of the cold air enters the seat 8 from the opening 8a provided in the front of the seat 8 of the seat, and is moved by the cross-flow fan 11 to the back. The sheet 8 and the backrest 9 are cooled in the backrest 9 and then discharged into the cabins 13 from the upper end of the backrest 9. The duct 4 connected to the left and right sides of the cooler 1 has a tip extending to the left and right of the seat, such as a blower 7 provided at the tip of the duct 4. The cool air blown out from each of the right and left outlets 7a cools the lower limb of the driver, and is then sucked into the inlet 3a on the lower surface of the cooler 1.
冷却風量は調節可能であ る。 ま た、 ダク ト 先端の冷風 吹き 出 し口 7 に設け られて い る グ リ ルの向き を調節して 、 冷風をすベて上方あ る い は下方に向ける こ と も でき る 。 そ のほか、 キ ャ ビ ン内面に沿って循環する 冷風のみで 十分な冷房効果が得られる場合は、 ク ロ ス フ ロー フ ァ ン のス ィ ッ チを O F F にする と と もに、 ダク ト 先端の吹き 出 し口 7 を閉鎖すればよ い。 The cooling air volume is adjustable. Also, by adjusting the direction of the grill provided in the cool air outlet 7 at the tip of the duct, all the cool air can be directed upward or downward. . In addition, if a sufficient cooling effect can be obtained only with cold air circulating along the inside of the cabin, switch off the cross-flow fan and turn off the duct. G The outlet 7 at the tip may be closed.
キ ャ ビ ン内暖房の場合は、 ヒ ータ 2 の前面に設け られ た吹き出 し口 6 か ら吹き出す温風が床面およ びキ ャ ビ ン 前面に沿 って上昇 し、 運転者の頭上を通って後方に流れ 、 座席 3 0 の背後を下降 して ヒ ータ の両側面に設け られ た吸い込み口 5 か ら吸い込まれる。 こ の と き温風の一部 は シー ト 前面に設け られた開口部 8 a か ら シー ト 内に入 り 、 ク ロ ス フ ロ ー フ ァ ン 1 1 に よ っ て シー ト 8 と 背当 て 9 内を流れ、 これ らを加熱 した後、 背当て 9 の上端開口 部 9 a か らキ ャ ビ ン内に排出さ れる 。 シー ト 前部に小形 ヒ ータ 1 2 を設け、 こ れを作動させた場合は、 室内を循 環する温風よ り 高温の風が シー ト 8 、 背当て 9 内を流れ る ので、 暖房効果が一層向上する。  In the case of heating inside the cabin, the warm air blown out from the outlet 6 provided in the front of the heater 2 rises along the floor and the front of the cabin, and the driver's It flows backwards above the head, descends behind the seat 30, and is sucked through suction ports 5 provided on both sides of the heater. At this time, a part of the warm air enters the seat through the opening 8a provided in the front of the seat, and is crossed by the cross-flow fan 11 to the back of the seat 8. After flowing through the inside of the backrest 9 and heating them, it is discharged into the cabin through the upper end opening 9 a of the backrest 9. If a small heater 12 is installed at the front of the seat and it is activated, the hot air circulating in the room will flow through the seat 8 and the backrest 9 so that the heating The effect is further improved.
ま た冷房時と同様に、 ク ロ ス フ ロ ーフ ァ ン 1 1 や小形 ヒ ータ 1 2 のス ィ ツ チを O F F にすれば温風の座席内流 通を止め る こ とができ る。  As in the case of cooling, turning off the switches of the cross-flow fan 11 and the small heater 12 can stop the hot air from flowing through the seat. You.
なお、 図示 しないがヒータか ら吹き出す温風の一部を 前記ダク ト 4 に導き、 暖房使用時にダク ト か ら温風が吹 き 出すよ う に して もよ い。  Although not shown, a part of the hot air blown out from the heater may be guided to the duct 4 so that the hot air blows out from the duct when heating is used.
ダ ク ト 4 は座席の肘掛け と一体に した もので も よ く 、 あ る いは座席両側に設けた操作バネ ルボ ッ ク ス と一体に し た も ので も よ い。 The duct 4 may be integrated with the armrest of the seat, or may be integrated with the operating spring box provided on both sides of the seat. Whatever you do.
こ の よ う に キ ャ ビ ン 1 3 内面に沿 っ て循環する 冷風 （ ま た は温風） によ って キ ャ ビ ン 1 3 内を適温に保つ と と も に、 座席内部を流通する 冷風 （ま た は温風） と、 ダク ト 4 から吹き 出す冷風 （ま た は温風） と によ っ て運転者 の皮膚表面を適切に冷却 （ ま た は加熱） する こ と によ り 、 運転者の稼働条件の向上を図っ た。  In this way, the cold air (or hot air) circulating along the inside of the cabin 13 keeps the cabin 13 at an appropriate temperature and distributes the inside of the seat. By appropriately cooling (or heating) the driver's skin surface with cold (or hot) air and cold (or hot) air blowing from duct 4 Therefore, the operating conditions of the driver were improved.
本実施例で は座席内部の加熱効果を高める ため、 シ ー ト 8 の通風孔開口部 8 a 付近に小形ヒータ 1 2 を設けた が、 稼働地域の環境条件等によ っ て は小形ヒ ータ 1 2 は 装着 しな く て もよ い。  In this embodiment, a small heater 12 is provided in the vicinity of the ventilation hole opening 8a of the seat 8 in order to enhance the heating effect inside the seat. However, a small heater may be provided depending on the environmental conditions in the operating area. It is not necessary to attach the data 12.
以上説明 したよ う に本発明によれば、 冷風ま た は温風 がキ ャ ビ ン 1 3 の内面に沿 って循環する経路 と、 運転者 の前後をそれぞれ流れる経路とから なる空調 シ ス テ ム を 構成 し、 こ れに必要な空調装置 2 0 と座席 3 0 と をキ ヤ ビ ン 1 3 内に設置 した ので、 運転者が所望す る状態にな る よ う に こ の空調装置 2 0 を適切に操作する こ と によ り 、 稼働地域， 季節， 日射等の環境条件によ っ て変化す る キ ャ ビ ン内温度あ る い は運転者の身体各部の表面温度を 、 年間を通 じて常に快適に保つ こ と がで き る。 こ れによ り 運転者の身体的および精神的負荷が著 し く 軽減され、 作業能率を向上させる こ とがで き る。 ま た、 座席 3 0 前 方に空調装置、 吹き 出 し口等を設置 しな い の で、 前方視 界は十分に確保す る こ とができ る。 産業上の利用可能性 本発明 は、 建設機械 * 農業機械等ある いは各種自動車 の運転者の身体各部の表面温度を、 常に快適に保つこ と がで き る キ ャ ビ ン内空調シ ス テ ム と 、 そ の空調装置およ び座席と して有用であ る。 As described above, according to the present invention, the air-conditioning system includes a path in which cold air or hot air circulates along the inner surface of the cabin 13 and a path in which the air flows before and after the driver. The air conditioner 20 and the seat 30 necessary for this were installed in the cabin 13 so that the air conditioner could be in the desired condition by the driver. By operating the 20 properly, it is possible to reduce the temperature inside the cabin or the surface temperature of each part of the driver's body, which changes depending on the environmental conditions such as the operating area, season, and solar radiation. You can always stay comfortable throughout the year. This significantly reduces the physical and mental burden on the driver and can improve work efficiency. In addition, since no air conditioner, outlet, etc. are installed in front of the seat 30, sufficient forward visibility can be secured. INDUSTRIAL APPLICABILITY The present invention relates to an air conditioning system in a cabin capable of constantly maintaining the surface temperature of each part of the body of a driver of a construction machine, an agricultural machine, or various kinds of automobiles. Useful for items and their air conditioners and seats.
