Description
【考案の詳細な説明】 本考案は局所冷房機に関するものである。[Detailed explanation of the idea] The present invention relates to a local air conditioner.
従来の局所冷房機を第1図および第2図に示すと、圧縮
器1により圧縮された高温・高圧冷媒ガスは吐出管2を
経て凝縮器3に入るが、ここで凝縮器側送風機4により
放熱液化し、凝縮器3を出た後キャピラチューブ5によ
り減圧され蒸発器6に入る。A conventional local air conditioner is shown in FIGS. 1 and 2. High-temperature, high-pressure refrigerant gas compressed by a compressor 1 enters a condenser 3 via a discharge pipe 2, where it is pumped by a blower 4 on the condenser side. After releasing heat and liquefying, it exits the condenser 3, is depressurized by the capillary tube 5, and enters the evaporator 6.
液化した冷媒は蒸発器6において蒸発器側送風機7によ
り送られる吸込空気8から吸熱ガス化し、吸入管9を経
て圧縮器1に戻る。The liquefied refrigerant is endothermically gasified in the evaporator 6 from the suction air 8 sent by the evaporator-side blower 7, and returns to the compressor 1 through the suction pipe 9.
以上の一般的な冷媒サイクルを構成する一連の機器が第
1図における外箱10の中に納められている。A series of devices constituting the above-mentioned general refrigerant cycle are housed in an outer box 10 in FIG.
この冷媒サイクルを行なう中で蒸発器側送風機7により
蒸発器側空気吸込口11から吸込まれた吸込空気8が蒸
発器6で吸熱され、冷却される際に生ずる結露水(ドレ
ン)はドレン受皿12に受けられ、ドレンタンク13に
貯えられる。During this refrigerant cycle, the suction air 8 sucked in from the evaporator side air suction port 11 by the evaporator side blower 7 absorbs heat in the evaporator 6 and is cooled. and stored in the drain tank 13.
外箱10にはキャスタ14が設けられている。The outer box 10 is provided with casters 14.
以上の構成により従来の本機はドレン処理の面でも外箱
10を固定する必要性がなく、本機は外箱10内にドレ
ンタンク13を設置している”ため、外箱10の制約を
受けない。With the above configuration, the conventional machine does not need to fix the outer box 10 in terms of drain processing, and this machine has the drain tank 13 inside the outer box 10. I don't accept it.
ドレンはドレンタンク13を外箱10より取出し放てき
する。For the drain, take out the drain tank 13 from the outer box 10 and set it aside.
本機はキャスタ14により移動も容易であるという特徴
を持つが、反面、凝縮器3からの放熱処理に難があった
。This machine has the feature of being easily movable due to the casters 14, but on the other hand, there was a problem in heat dissipation from the condenser 3.
即ち、本機は蒸発器側空気吸込口11から吸込まれ蒸発
器側吹出口15から吹出す冷却された蒸発器側吹出空気
16をスポット的に冷却対象物に当てる使い方をし、凝
縮器側空気吸込口17から吸込まれ凝縮器側吹出口18
から吹出す加熱された凝縮器側吹出空気19は冷却対象
物以外の方向へ逃がす方法しかなかった。That is, this machine uses cooled evaporator-side air 16 that is sucked in from the evaporator-side air suction port 11 and blows out from the evaporator-side air outlet 15 to hit the object to be cooled in spots, and the condenser-side air Sucked in from the suction port 17 and the condenser side outlet 18
The only way to release the heated air 19 from the condenser side is to release it in a direction other than the object to be cooled.
従って、本機を密閉した部屋などで使用すると、吸熱量
より放熱量の方が大きいため、室温は運転と共に上昇し
て行くことになり、このため開放した部屋などで使い、
凝縮器3の放熱量を室外に逃がすような使い方をせざる
を得なかった。Therefore, if you use this machine in a closed room, etc., the amount of heat dissipated is greater than the amount of heat absorbed, so the room temperature will rise as you operate.
There was no choice but to use the condenser 3 in such a way that the amount of heat dissipated was released outside.
この点を改良するため凝縮器側吹出口18に蛇腹状の可
撓な排気ダクト20を取り付け、移動容易であるという
特徴を殺さないよう、加熱された凝縮器側吹出空気19
を室外へ逃す工夫がなされたが十分でなかった。In order to improve this point, a bellows-shaped flexible exhaust duct 20 is attached to the condenser side outlet 18, and heated condenser side outlet air 19 is installed so as not to destroy the characteristic of easy movement.
Efforts were made to allow the water to escape outside, but it was not sufficient.
他のタイプとしてドレンを室外に排水する冷房機があり
、この場合ドレンホースを用い、ドレンホースの一端を
ドレン受皿12に連結し、他端を室内の壁に穿けた穴等
を介して室外に出すようにしているが、場所はドレンホ
ースの設置状態により規制されることになり、本体の移
動は制約された。Another type is an air conditioner that drains the drain outdoors.In this case, a drain hose is used, one end of which is connected to the drain tray 12, and the other end is drained outdoors through a hole made in the indoor wall. However, the location was restricted depending on how the drain hose was installed, and movement of the main body was restricted.
本考案は上記従来の不具合を解消したもので、凝縮器か

31に入っている。The water heat exchanger 21 has a water supply connection port 23 and a drainage connection port 24 for supplying and discharging water for cooling, and a water supply connection port through hole 25 and a drainage connection port through hole 26 provided in the outer box 10.
Flexible hoses 27 and 28 are connected to the water supply connection port 23 and the drainage connection port 24 through them, respectively.The flexible hose 27 is connected to the discharge side of the water pump 29, and the flexible hose 30 is connected to the suction side of the water pump 29. The end of the flexible hose 28 is connected to the water storage container 31, and one end of the flexible hose 28 is also inserted into the water storage container 31.

The bimetal thermoswitch 32 and the condenser-side ventilation motor 34 connected in series are connected in parallel, and energization of these is performed by opening and closing a switch 37.
なお、38は電源プラグである。Note that 38 is a power plug.
次に本考案の作用を述べると、可撓ホース27.28を

プ29を駆動し、貯水容器31内の水を循環させる。Next, the operation of the present invention will be described. The flexible hoses 27 and 28 are connected to the water supply connection port 23 and the drainage connection port 24, respectively, and the water pump 29 is driven to circulate the water in the water storage container 31.
一方、圧縮器1により圧縮された高温高圧冷媒ガスは吐
出管2を経て水熱交換器21に入り、循環水と熱交換(
放熱)し、配管22を得て凝縮器3に入る。On the other hand, the high-temperature, high-pressure refrigerant gas compressed by the compressor 1 enters the water heat exchanger 21 through the discharge pipe 2, and exchanges heat with the circulating water (
heat dissipation) and enters the condenser 3 through a pipe 22.
凝縮器3に入った冷媒ガスは凝縮器側送風機4により送
られる吸込空気8と熱交換(放熱)し、高圧液冷媒とな
って凝縮器3を出る。The refrigerant gas that has entered the condenser 3 exchanges heat (radiates heat) with the suction air 8 sent by the condenser-side blower 4, and exits the condenser 3 as a high-pressure liquid refrigerant.
高圧液冷媒はキャピラチューブ5により減圧され、低圧

媒となって吸入管9を経て圧縮器1に戻る。The high-pressure liquid refrigerant is depressurized by the capillary tube 5, becomes a low-pressure liquid refrigerant, enters the evaporator 6, exchanges heat (absorbs heat) with the suction air 8 sent by the evaporator-side blower 7, becomes a low-pressure gas refrigerant, and enters the suction pipe. 9 and returns to the compressor 1.
このサイクルにおいて水の循環により水熱交換器21の
出口の配管22を通る冷媒は、水を循環しない時より温
度が下っている。In this cycle, due to the circulation of water, the temperature of the refrigerant passing through the pipe 22 at the outlet of the water heat exchanger 21 is lower than when water is not circulated.
この温度変化をバイメタルサーモスイッチ32が検知し
てその接点を切換え、凝縮器側送風機用モータ34の回
転数を変える。The bimetal thermoswitch 32 detects this temperature change and switches its contact to change the rotation speed of the condenser side blower motor 34.
即ち、循環水により冷媒温度が下げられた場合は、凝縮
器側送風機用モータ34の回転数が落され、風量が減る
。That is, when the refrigerant temperature is lowered by the circulating water, the rotation speed of the condenser side blower motor 34 is lowered, and the air volume is reduced.
逆に水が循環されない場合や、循環されでも水温が十分
高く冷媒温度が下らない場合は回転数は落されず、通常
送風される。Conversely, if the water is not circulated, or if the water temperature is sufficiently high and the refrigerant temperature does not drop even if it is circulated, the rotational speed will not be reduced and air will be blown normally.
水ポンチ29の代りに直接水道から給水してもよい。Instead of the water punch 29, water may be supplied directly from the tap.
