Problems to be Solved by the Invention Not only in the above-mentioned publications but also in these showcases,
A fluorescent lamp as a lighting device is provided between the upper storage room and the lower storage room, that is, below the partition wall to illuminate the lower storage room, and a sliding door of the lower storage room is provided below the partition wall. It is common practice to form a door storage section for storing the door when it is opened, and a fluorescent lamp is arranged at one corner of the door storage section, that is, in the front, so that the cool air generated by cooling the lower storage room can be reduced. Due to the influence and storage of the cooled door, the door storage portion is also likely to be in a cooled state. In addition, when the fluorescent lamp is lit, the interior of the lighting unit is so small that heat is trapped in the lighting unit, and the synthetic resin plate near the fluorescent lamp is deformed by the action of the heat. The drawback is that the life of the fluorescent lamp is shortened at high temperatures, and when the fluorescent lamp is turned off, part of the cool air that cools the inside of the refrigerator hits the surface of the fluorescent lamp, resulting in fluorescent light. There is a drawback that dew condensation occurs on the surface of the lamp and the dew enters the fittings of the fluorescent lamp and shortens the life of the fluorescent lamp.

Therefore, in order to eliminate the above drawbacks, the present invention guides a part of the exhaust gas discharged from the machine room into the lighting unit between the upper storage unit and the lower storage unit without requiring special heating means,
When the fluorescent lamp of the lighting device is turned on, the fluorescent lamp is cooled to prevent heat from being trapped in the lighting unit, and when the fluorescent lamp is turned off, the purpose is to prevent condensation of the fluorescent lamp. It is.

To store. Drainage such as defrost water from the plate fin type cooler 17 of the upper case 4 is supplied to the rear of the door storage portion 25.
Outlet pipe 27 arranged through bottom wall 3E to lead out
The drainage pipe 28 extending to the drainage tray 44 of the machine room 40 via the space P is connected to the outlet pipe 27. The machine room 40 communicates with the air P, and since this space P communicates with the door storage unit 25, warm air generated in the machine room 40 (shown by a thin line arrow called warm air) is in the machine room.
The air discharged from the exhaust port 45 at the rear of the airbag 40 to the outside of the machine room 40 is directed to the illumination unit 26 through the warm air passage 29 formed by the space P and the door storage unit 25 by changing the direction at the lower part of the rear cover. (In the present example, the former: the latter = approximately 9: 1).

The lighting part 26 is formed in the left-right direction below the front part of the bottom wall 3E of the heat insulating wall 3 and includes a fluorescent lamp 51 detachably attached to the clip 50 and a hinge 10 disposed directly below the transparent door 11. It has flexibility and translucency to lock its upper end in the locking groove 52A of the fixed exposure receiving rail 52 and to lock its rear end to the fixing piece 54B of the fixing member 54 to which the clip 50 is fixed. A shade 55 made of resin is provided. It is desirable that the fixing piece 54B also has flexibility. Then, by using the flexibility to fix the shade 55, the gap between the upper end of the shade and the locking groove 52A and the rear end of the shade and the fixing piece 54B are fixed.
And a slight gap is formed between them, and this gap becomes an air passage for discharging the air in the illumination unit 26 to the outside, and the air can be circulated through the gap.

Here, the outside air taken into the machine room 40 is heated by exchanging heat in the condenser 42 or removing heat of the compressor (the temperature is about 40 ° C. as described later). The air is blown to the exhaust port 45 side. Most of the warm air is exhaust vent 45
However, since the rear of the machine room 40 and the space P communicate with each other and the lower end of the cover 43 is exposed to warm air, a part of the warm air is guided to the space P (see the dashed line), and the door is stored. The light is discharged to the outside through the gap formed in the lighting unit 26 as shown by the dashed line in FIG. The outside air temperature of the machine room 40 is 30
Because it is usually heated to about 40 ° C at ℃, drain pipe
Dewdrops generated in 28 and the door storage unit 25 are gradually vaporized and carried to the front of the door storage unit. When the fluorescent lamp is turned on, the temperature in the lighting unit is higher than the temperature of the guided warm air when the fluorescent lamp is turned on, so that the inside of the lighting unit 26 is cooled and turned off. Sometimes lighting
It will be heated within 26. Then, the evaporating and evaporating of the dew that accumulates on the dew receiving rail 52 can be promoted by the warm air emitted from the lighting unit 26.

According to the above configuration, the outside air taken into the machine room 40 is warmed by heat exchange with the machine parts in the machine room, and is discharged to the outside of the machine room.
Of the door storage section 25
The lighting section 26 and the lighting section selected in the lighting section 16
Discharged below 26. At this time, the drain pipe 28 in the space P
And the top wall of the door storage unit 25, that is, the bottom wall 3E of the heat insulating wall 3 and the like, and gradually evaporate and evaporate while contacting with the exposed surface attached to the lower surface. On the other hand, when the dew is evaporated and evaporated, or gradually cooled warm air is introduced into the illumination unit 26 by contact with other parts, (i) if the fluorescent lamp 51 is on, the radiant heat by the lighting (2) If the fluorescent lamp 51 is turned off, the dew adhering to the inner surface of the lighting unit 26 evaporates. After acting to vaporize, it is discharged to the outside from the gap formed around the end of the shade 55 and the door entrance part of the door storage part 25, enabling the removal of water droplets on the surface of the sliding door 30 I have. Therefore, it is possible to efficiently use the warm air of the machine room 40 generated by performing the cooling operation and the dew prevention of the door storage unit 25 and the storage unit 26, and to suppress the temperature rise in the illumination unit 26. . Further, since the piping is performed using the space P, the surface of the piping can be heated.

As described in detail above, according to the present invention, a warm air passage that guides air that has been taken into the machine unit and is heated by heat exchange with parts in the machine unit into the lighting unit, and an air passage that discharges air in the lighting unit to the outside By forming a flow of air that is discharged from the machine room through the warm air passage and the inside of the lighting unit to the outside through the air passage, ventilation of the lighting unit is improved when the lighting device is turned on, and the inside of the lighting unit is improved. As the heat stops,
When the lamp is turned off, it is possible to prevent condensation of the fluorescent lamp in the lighting unit. In particular, since the relative humidity of the air heated by the mechanical unit is reduced, it is possible to dehumidify the warm air passage leading to the lighting unit. In addition, since the warm air that has been simply discharged is effectively used, a special device for preventing heat from being trapped in the lighting unit and preventing dew condensation is not required.

また、排水管を暖気通路内に設けたことにより、除露
水等の冷たい排水を導出するための排水管の表面に暖気
が通過し、排水管の表面に発生した露滴を徐々に蒸発気
化させることにより、排水管の表面の結露を抑止するこ
とができる。
In addition, since the drain pipe is provided in the warm air passage, warm air passes through the surface of the drain pipe for deriving cold drainage such as dew water, and the dew drops generated on the surface of the drain pipe are gradually evaporated and vaporized. Thereby, dew condensation on the surface of the drain pipe can be suppressed.

更に、暖気通路を排水管の配設路にも兼用することが
できるので下部貯蔵部の構成を簡略化することもでき
る。
Further, the configuration of the lower storage section can be simplified since the warm air passage can also be used as the drain pipe arrangement path.
