図５に示すように、冷蔵庫の背面下部の空間部１はカバー１４によって覆われており、カバー１４には開口部１５が設けられ、この開口部１５から蒸発皿４の排水用切欠き部４ｆが外部に貫通するようになっている。   As shown in FIG. 5, the space 1 at the lower back of the refrigerator is covered with a cover 14, and the cover 14 is provided with an opening 15, through which the drainage cutout 4 f of the evaporating dish 4 is provided. Penetrates to the outside.

次に動作について説明する。
冷蔵庫の運転時において、冷凍室８の背面に配置された冷却器９に霜が付着すると、この霜は霜取り用ヒータ１１によって加熱されて除霜水として水受け部１２に落下し、ここから水受け排水管１２ａを通過して排水管６を通り、蒸発皿４内に導かれる。排水管６の先端部６ａは蒸発皿４の第１の底面４ｂに位置しているので、除霜水は吐出管７に直接当たることなく蒸発量の多い吐出管７付近の蒸発皿４内に流入する。蒸発皿４内の除霜水は、吐出管７及び圧縮機２の熱と、圧縮機冷却用送風機５の吸込み側から吹出し側への空気の強制対流とにより蒸発して、冷蔵庫周囲の空間に放出される。
冷蔵庫を引越し等により運搬して移動させるときは、カバー１４を外すことなく、冷蔵庫全体を後方に傾けて、除霜水を排水用切欠き部４ｅから開口部１５を通して冷蔵庫の外に排出する。 Next, the operation will be described.
During operation of the refrigerator, when frost adheres to the cooler 9 disposed on the back surface of the freezer compartment 8, the frost is heated by the defrosting heater 11 and falls to the water receiving portion 12 as defrost water, from which water It passes through the drainage pipe 12a, passes through the drainage pipe 6, and is led into the evaporating dish 4. Since the front end portion 6a of the drain pipe 6 is located on the first bottom surface 4b of the evaporating dish 4, the defrost water does not directly hit the discharge pipe 7, but enters the evaporating dish 4 near the discharge pipe 7 where the evaporation amount is large. Inflow. The defrost water in the evaporating dish 4 evaporates by the heat of the discharge pipe 7 and the compressor 2 and the forced convection of air from the suction side to the blower side of the compressor cooling blower 5, and enters the space around the refrigerator. Released.
When transporting and moving the refrigerator by moving or the like, the entire refrigerator is tilted rearward without removing the cover 14, and defrost water is discharged from the drainage notch 4 e through the opening 15 to the outside of the refrigerator.

冷蔵庫の運転時には、以上のようにして除霜水を蒸発させるようにしたので、上下の狭い空間に蒸発皿４と圧縮機冷却用送風機５とを配置しても、除霜能力を低下させることなく除霜水を蒸発させることができる。この場合、圧縮機冷却用送風機５の吸込み側、吹出し側に蒸発皿４の脚部４０、４１が配置されているので、蒸発皿４に溜まっている除霜水表面の空気の対流を増加させることができる。
そして、排水管６の先端部６ａは蒸発皿４と一体成形された爪部４ａに取り付けられて固定されているので、除霜水は蒸発皿４内に確実に導入され、蒸発皿４以外に水が飛び散ったり床に水漏れが生じるのを防ぐことができる。また、吐出管７の下部の蒸発皿４内にリブ４ｄを設けたので、吐出管７が蒸発皿４の底面に接触することがなく、穴あきによる水漏れを防止することができる。さらに、排水管６を圧縮機冷却用送風機５の吹出し側に配置したので、圧縮機２の熱と圧縮機冷却用送風機５からの送風によって除霜水が凍結することがないため、凍結による詰まりを防止することができる。 Since the defrost water is evaporated as described above during the operation of the refrigerator, even if the evaporating dish 4 and the compressor cooling blower 5 are arranged in the upper and lower narrow spaces, the defrosting ability is reduced. Without defrosting water can be evaporated. In this case, since the leg portions 40 and 41 of the evaporating dish 4 are arranged on the suction side and the outlet side of the compressor cooling blower 5, the convection of the air on the surface of the defrost water collected in the evaporating dish 4 is increased. be able to.
And since the front-end | tip part 6a of the drain pipe 6 is attached and fixed to the nail | claw part 4a integrally molded with the evaporating dish 4, defrost water is reliably introduce | transduced in the evaporating dish 4, and other than evaporating dish 4 It is possible to prevent water from splashing and water leakage from the floor. Moreover, since the rib 4d is provided in the evaporating dish 4 below the discharge pipe 7, the discharge pipe 7 does not contact the bottom surface of the evaporating dish 4, and water leakage due to perforation can be prevented. Further, since the drain pipe 6 is arranged on the outlet side of the compressor cooling blower 5, the defrost water is not frozen by the heat of the compressor 2 and the air blown from the compressor cooling blower 5, and therefore clogging due to freezing. Can be prevented.

一方、冷蔵庫を引越し等により運搬して移動させるときは、カバー１４に蒸発皿４内の除霜水を排水する開口部１５を設けたので、カバー１４を外すことなく冷蔵庫全体を後方に傾けて、排水用切欠き部４ｅから開口部１５を通して除霜水を冷蔵庫の外に排出することができるため、排水作業を短時間に終えることができる。また、排水箇所を複数設けたので、蒸発皿４の排水用切欠き部４ｆ以外からの水漏れを防止することができる。   On the other hand, when the refrigerator is moved and moved by moving or the like, the cover 14 is provided with the opening 15 for draining the defrosted water in the evaporating dish 4, so that the entire refrigerator is tilted rearward without removing the cover 14. Since defrost water can be discharged out of the refrigerator through the opening 15 from the drainage notch 4e, the drainage operation can be completed in a short time. Moreover, since the several drainage location was provided, the water leak from other than the notch 4f for drainage of the evaporating dish 4 can be prevented.

実施の形態２．
実施の形態１では排水管６を圧縮機冷却用送風機５の吹出し側に配設したが、実施の形態２では圧縮機冷却用送風機５の吸込み側に配設したものである。
図６に示すように、排水管６は圧縮機冷却用送風機５の吸込み側に配置されており、さらに、圧縮機冷却用送風機５のファン部５ａの投影面の外側に位置する。
このように排水管６を配置したので、圧縮機冷却用送風機５から圧縮機２への送風量が増加して圧縮機２の能力を向上させ、消費電力量を削減することができる。 Embodiment 2. FIG.
In the first embodiment, the drain pipe 6 is disposed on the outlet side of the compressor cooling blower 5, but in the second embodiment, the drain pipe 6 is disposed on the suction side of the compressor cooling blower 5.
As shown in FIG. 6, the drain pipe 6 is disposed on the suction side of the compressor cooling blower 5 and is located outside the projection surface of the fan portion 5 a of the compressor cooling blower 5.
Since the drain pipe 6 is arranged in this manner, the amount of air blown from the compressor cooling blower 5 to the compressor 2 is increased, the capacity of the compressor 2 is improved, and the power consumption can be reduced.

実施の形態３．
実施の形態１、２ではほぼＵ字形状の蒸発皿４を設けた場合を示したが、実施の形態３はこのＵ字状の蒸発皿４の切欠き溝４３にさらにフランジ等を取り付けたものである。
図７において、ほぼＵ字形状の蒸発皿４の切欠き溝４３を跨いで両脚４０、４１を接続するフランジ４ｇが設けられており、蒸発皿４と一体に成形してある。また、フランジ４ｇにはネジ固定用の穴部が設けられ、蒸発皿４の下部の台板１６に当接させて、フランジ４ｇの穴を通してフランジ４ｇを台板１６にネジ固定してある。 Embodiment 3 FIG.
