公報はこの点についても言及されてないものであった。A conventional refrigerator of this type has a machine room 3, as shown in Utility Model Application Publication No. 58-190378 (Figs. 9 and 10), and a machine room cover 4 is provided to cover the opening of the machine room. Together with this cover 41, the evaporating dish inlet/outlet 6 and the inlet/outlet 6
An evaporating dish support stand 7 connected to the evaporating dish support stand 7 is provided, and by placing the evaporating dish 5 inserted through the evaporating dish inlet/outlet 6 on this support stand 7, the evaporating dish 5 is placed above the compressor 2 and inside the refrigerator. Is it indicated whether the position 1 where the defrosting water is drawn from the cooler is placed away from the compressor 2? There were various problems in efficiently evaporating the defrosting water in the cooler. In other words, in order to increase the evaporation efficiency of the evaporating dish, it is necessary to efficiently conduct the heat from the compressor to the evaporating dish to raise the temperature of the water in the evaporating dish as much as possible, and to improve the convection of the air around the evaporating dish so that the temperature after evaporation increases. There was not much mention of this seafood promotion plan, whether it was necessary to quickly release the humid air outside the machine room so that fresh air could be sucked in instead. Furthermore, while the refrigerator is operating, the above publication also mentions whether it is the vibration of the compressor or the vibration of the evaporator tray placed on the refrigerator body that generates resonance noise from time to time. It had never been done before.

An air passage is formed between the handle 24 and the front wall 18C of the evaporating dish, and a slit 25 is formed in the handle part corresponding to the upper end of the passage. It is provided. Of course, this slit 25 efficiently discharges the air sucked in from the slit 26 which is an air suction port provided in the machine room cover 16 and warmed by the compressor 17 to the outside of the machine room to promote evaporation in the evaporating dish 18. It was created to allow 24a is the evaporating dish 17
This locking portion 24 is provided at both ends of the handle 24.
The anti-camera rubber 21 deposited on the machine room cover 16 described above is shown in a.
One evaporating dish 18 is attached to the machine room cover 16 so that the surface of the evaporating dish handle 24 is substantially the same as the machine room cover 16 by locking the head 21a of the evaporating dish 18.

。Next, the machine room cover 16 of the present invention will be explained. As shown in the figure, the machine room cover 16 has a slit 26 serving as an air inlet to the machine room 14, and also has a slit 26 which is an air inlet to the machine room 14.
7. Further, a vibration isolating rubber 21 is fitted onto the side wall 16a surrounding the evaporating dish 18, as shown in FIGS. 6 and 7.

Air that passes through the slit 25 and is sucked in through the gap 28 between the base 15 and the bottom plate 11a of the refrigerator body passes through the recess 23 provided in the evaporating dish 18 and the air vent chimney 22, and both pass through the upper surface of the evaporating dish 18 and the machine room. It is discharged to the outside of the machine room 14 through a gap 29 between the ceiling surfaces.

蒸発皿１８内の除霜水の蒸発が促進される。At this time, in the present invention, the slit 26 serving as the air suction port is provided below the position of the evaporation plate 18 installed above the compressor 17, so all the air sucked through the slit 26 is warmed by the compressor 17 and rises. Since the defrosting water is discharged outside the machine room 14 as an air current, the convection of the air around the evaporating dish 18 becomes good, and the evaporation of the defrosting water in the evaporating dish 18 is promoted.

・＾（ｌガ効に働にとは云うまでもない。Evaporation of defrosting water in a refrigerator having such a configuration is performed as follows. That is, the defrosting water of the cooler is first passed from the refrigerator interior 12 through the defrosting water conduit outlet 19 to the partition wall 18b of the evaporating tray 18.
Water is introduced into a small chamber at the top of the compressor formed by In this part, the bottom part 18a of the evaporating dish is made of flexible rubber 20 with good thermal conductivity.
Since the water temperature is the highest because it is in direct contact with the upper part of the compressor and almost matches the shape of the upper part of the compressor, the evaporating dish 181 also has the air vent chimney 22, the recess 23 forming the air passage, the totte 24, and the front wall 18c. Since a slit 25 is provided on the top surface of the totte, the air sucked in from the gap 28 between the base 15 and the bottom plate 11a and the slit 26 of the machine room cover is transferred to the compressor 1 as shown in FIG.
7 becomes an upward air current that heats the evaporating dish 18 and is also discharged from the machine room 14 from the gap 29. As a result, the temperature of the water inside the evaporating dish 18 rises and the temperature around the evaporating dish 18 (especially the evaporating dish 18) increases. Since the convection of air on the upper surface of the tray (related to the evaporating tray 18) becomes active, evaporation of the defrosting water in the evaporating tray 18 is promoted. Of course, it goes without saying that at this time, the machine room 14 is depicted as being very effective.

。Furthermore, in the present invention, since the slit 26, which is the air suction port opened in the machine room cover 161, is located below the position of the evaporating dish 18 installed on the compressor 17, all the air sucked through the slit 26 is compressed by $17. When the evaporating plate 18 is heated and the rising air current is heated, the convection area of the air around the evaporating plate 18 is increased, so that the efficiency of evaporation is further improved.

尚、冷却器の除霜水か蒸発皿１８の圧縮機上部の小室の

の部分からも蒸発は行われる。In addition, when the defrost water of the cooler exceeds the capacity of the small chamber above the compressor of the evaporating dish 18, it will overflow into the next small chamber.
Of course, evaporation also occurs from this part, although the amount of evaporation is smaller than from the small chamber at the top of the compressor.

Since the compressor 17 is elastically supported by the vibration isolating rubber 21 of the machine room cover and the refrigerator, the vibration noise of the compressor 17 does not propagate and generate resonance noise from the evaporating plate 18 when the refrigerator is operated. Furthermore, a cut-and-raised piece 30 is provided using a part of the rib forming the slit 26 of the machine room cover, and the cut-and-raised piece 30
The power cord 31 can be easily disposed of when installing the refrigerator, since the cord 31 can be hung on the refrigerator.

Since the slit that forms the air suction port into the machine room provided in the machine room cover is provided below the position where the evaporating dish is installed, the air sucked through the slit is All of the air is heated by the compressor and becomes an upward air current that heats the evaporating dish and increases the convection flow rate of the air around the evaporating dish, so that the defrosting water in the evaporating dish is efficiently evaporated.
