本考案はヒートポンプ式空気調和機の室外ユニ
ツトの改良に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of an outdoor unit of a heat pump type air conditioner.
第３図及び第４図に基づいて、従来のヒートポ
ンプ式空気調和機の室外ユニツトの底板ドレンパ
ン部分の構造を示す。
3 and 4, the structure of a bottom plate drain pan portion of an outdoor unit of a conventional heat pump type air conditioner is shown.
図中において、１１は底板ドレンパン本体、１
２はドレンパン部分、１３はドレンパン部分１２
に配設されたヒータ、１４は排水口を示す。 In the figure, 11 is the bottom plate drain pan body, 1
2 is the drain pan part, 13 is the drain pan part 12
14 indicates a drain port.
第４図は熱交換器が置かれる部分の断面図を示
したもので、１５は熱交換器、１６は室外ユニツ
トを支える足である。 FIG. 4 shows a cross-sectional view of the part where the heat exchanger is placed, where 15 is the heat exchanger and 16 is the leg that supports the outdoor unit.
一般に、ヒートポンプ式空気調和機は室外ユニ
ツトの熱交換器１５で室外空気から熱交換器を吸
熱するため、空気中の水分が熱交換器１５の表面
で凝縮し、ドレンパン部１２にドレン水となつて
溜まり、このドレン水は排水口１４を介して外へ
排水されるようになつている。 Generally, in a heat pump type air conditioner, the heat exchanger 15 of the outdoor unit absorbs heat from the outdoor air, so moisture in the air condenses on the surface of the heat exchanger 15 and becomes drain water in the drain pan section 12. This drain water is drained to the outside through a drain port 14.
なお、ヒータ１３はドレンパン部１２でのドレ
ン水の凍結を防ぐためのものである。 Note that the heater 13 is provided to prevent drain water from freezing in the drain pan section 12.
ヒートポンプ式空気調和機は、室外温度が下が
ると熱交換器１５の表面温度も下がり結氷し始め
る。そのままでは、熱交換器１５は、氷で覆われ
て室外空気との熱交換ができなくなり、吸熱能力
が減少し、暖房能力も減少するため、デフロスト
運転に入り、熱交換器１５の表面の結氷を融かす
ようにしている。
In the heat pump type air conditioner, when the outdoor temperature drops, the surface temperature of the heat exchanger 15 also drops and ice begins to form. If left as it is, the heat exchanger 15 will be covered with ice and will not be able to exchange heat with the outdoor air, reducing its heat absorption capacity and decreasing its heating capacity. I'm trying to melt it.
この時の融解水がドレンパン部１２へ流れ落ち
て排水口１４から排水されるが、室外温度が非常
に低い場合、ドレンパン部１２へ流れ落ちた融解
水が排水口１４から排水される前にドレンパン部
１２で再凍結する。このため、ドレンパン部１２
にヒータ１３を設置してドレン水の再凍結を防ぐ
ようにしている。 The melted water at this time flows down to the drain pan section 12 and is drained from the drain port 14, but if the outdoor temperature is very low, the melted water that has flowed down to the drain pan section 12 is drained from the drain pan section 12 before being drained from the drain port 14. Refreeze. For this reason, the drain pan section 12
A heater 13 is installed to prevent the drain water from refreezing.
しかし、ドレンパン部１２の表面積は広く、全
域にヒータを設けて凍結を防ぐようにすると電気
消費量が多くなると共に、熱交換器１５の周囲に
はヒータを設置するスペースがないため、この部
分がヒータから遠く凍結することがあるなどの問
題点があつた。 However, the surface area of the drain pan section 12 is large, and if a heater is installed in the entire area to prevent freezing, electricity consumption will increase, and there is no space to install a heater around the heat exchanger 15, so this area is There were problems such as freezing occurring far away from the heater.
また、一度凍結すると、なかなか融解せず運転
中凍結量はどんどん進行し、そのうち熱交換器１
５の下部のパイプが氷によりつぶされて冷媒が放
出し、ひいては運転不能となる問題点があつた。 In addition, once frozen, it does not thaw easily and the amount of freezing progresses rapidly during operation, and eventually the heat exchanger 1
There was a problem that the pipe at the bottom of No. 5 was crushed by ice and the refrigerant was released, making it impossible to operate.

In an outdoor unit of a heat pump type air conditioner in which a heat exchanger is installed on a drain pan, a heat exchanger installation portion of the drain pan is made to protrude upward in a rail shape, and a heater is disposed on the rail-like protrusion, A heat exchanger is installed on top of the heat exchanger through an L-shaped heat transfer material that has a flange that prevents drain from flowing into the drain pan, and drain water that falls from the heat exchanger is directly discharged to the outside of the outdoor unit. This is an outdoor unit of an air conditioner with a discharge section.
上記構成によると、ヒータをドレンパン全域に
設ける必要がなくなると共に熱交換器から落下し
たドレンは直ちに外部へ排出されるため、熱交換
器下部付近で再凍結することもなくなる。
According to the above configuration, there is no need to provide a heater over the entire drain pan, and since drain that has fallen from the heat exchanger is immediately discharged to the outside, there is no possibility of refreezing near the bottom of the heat exchanger.
以下に本考案の一実施例を第１図及び第２図に
基づいて説明する。
An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
図中、１は底板ドレンパン本体、２は熱交換器
９を設置する上方へレール状に突出されたレール
状突出部、３は排水口、４はドレンパン部分、５
はドレンパン部分の排水口、６は突出部に配設さ
れたヒータ、７は突出部２と熱交換器間に介装さ
れ、ドレンパン部分側にフランジを有するＬ字形
の伝熱材、８は室外ユニツトを支える足である。 In the figure, 1 is the bottom plate drain pan main body, 2 is a rail-shaped protrusion that protrudes upward in a rail-like manner on which the heat exchanger 9 is installed, 3 is a drain port, 4 is a drain pan part, 5
is the drain port of the drain pan section, 6 is the heater disposed on the protrusion, 7 is an L-shaped heat transfer material interposed between the protrusion 2 and the heat exchanger and has a flange on the drain pan side, 8 is the outdoor These are the legs that support the unit.
上記構成において、デフロスト運転により熱交
換器９からの融解水は下方へ流れ落ちる。ヒータ
６は室外温度が低い時あるいは熱交換器９の温度
が低い時通電されて、Ｌ字形伝熱材７を介して、
熱交換器９とレール状突出部２に伝熱され、排水
口３の凍結防止と熱交換器９の下部付近の凍結を
防ぐ。 In the above configuration, the molten water from the heat exchanger 9 flows downward due to the defrost operation. The heater 6 is energized when the outdoor temperature is low or when the temperature of the heat exchanger 9 is low, and through the L-shaped heat transfer material 7,
Heat is transferred to the heat exchanger 9 and the rail-shaped protrusion 2, preventing the drain 3 from freezing and the vicinity of the lower part of the heat exchanger 9 from freezing.
Ｌ字形伝熱材７は熱交換器９より幅が広く、か
つＬ字形にしてあり、融解水のすべてを排水口３
から室外ユニツトの外へ排水できるようにしてあ
るので、ドレンパン部分に流れ落ちることがな
い。 The L-shaped heat transfer material 7 is wider than the heat exchanger 9 and is L-shaped, and drains all of the melted water to the drain port 3.
Since the water can be drained from the outside of the outdoor unit, there is no chance of water flowing down into the drain pan.
また、ドレンパン部分４に降雪、降雨等により
水が溜まつた場合は、排水口５から排水される。、
なお、このドレンパン部分４の水が凍結しても、
熱交換器９は、レール状突出部上に設置されてい
るため、熱交換器９まで氷が生長するには、かな
りの長時間を要するので実用上問題はなくなる。 Further, when water accumulates in the drain pan portion 4 due to snowfall, rainfall, etc., it is drained from the drain port 5. ,
Furthermore, even if the water in this drain pan section 4 freezes,
Since the heat exchanger 9 is installed on the rail-shaped protrusion, it takes a considerable amount of time for ice to grow to the heat exchanger 9, so there is no problem in practical use.
以上のように本考案によればヒータにより温め
られるＬ字形伝熱材を熱交換器の下部に介装して
あるため、熱交換器からの融解水はすべてＬ字形
伝熱材７受けて外部へ排水される。従つて、熱交
換器下部付近での再凍結はなく、従来のような熱
交換器のパイプのつぶれによる運転不能を解消で
きると共にヒータの設置域を少なくし、電気消費
量の低減を図ることができる。
As described above, according to the present invention, since the L-shaped heat transfer material that is heated by the heater is installed at the bottom of the heat exchanger, all the melt water from the heat exchanger is received by the L-shaped heat transfer material 7 and external. is drained to. Therefore, there is no refreezing near the bottom of the heat exchanger, which eliminates the problem of inoperability caused by collapsed pipes of the heat exchanger, and also reduces the installation area of the heater and reduces electricity consumption. can.
