1b and the heat insulating member 41c are isolated from the cool air flow. This prevents cold air flowing through the cold air passage 27 from entering the refrigerator compartment 11 from the opening 41a. As a result, it is possible to prevent the local cooling of the refrigerator compartment 11 from being excessively cooled due to the cold air leakage, and further to prevent the dew condensation around the blower cover 41, the local excessive cooling due to the cold air outflow, and the freezing of the stored product due to the local cooling. I can do it.

When the flow of the cool air is stronger than that of the cool air, the cool air on the side of the refrigerator compartment 11 flowing through the filter 41b flows into the blower 29 also through the heat insulating member 41c, and the filter 41 further increases.
The functional effect of b is improved.

If the upper wall surface portion leading to a is formed to be slightly inclined so as to be lower as it goes to the discharge portion 70b side, the discharged cool air flows out downward, and further, it is provided above. The influence of the cold air on the temperature detecting means 75 is eliminated, and the inside of the refrigerator can be kept at an appropriate temperature. Note that the same effect as described above can be obtained by providing a projection corresponding to the shielding plate 70f on the upper part of the discharge part 70b so as to be inclined downward as it goes forward.

Since the cool air passing through the central passage 28a is diffused right and left before flowing into the ceiling duct 54, the cool air is sufficiently discharged from the ceiling discharge port 43a provided at a position near the back plate 70 of the refrigerator compartment 11. For this reason, cool air falls from the entire area of the ceiling of the refrigerator compartment 11, which helps to make the temperature in the refrigerator uniform. Note that an illumination lamp 51 covered with a transparent illumination cover 53 is provided between the left and right ceiling ducts 54.

A part of the cold heat of the cool air passing through a conducts through the member 42 functioning as a heat conducting plate, and is discharged into the refrigerator compartment 11 from the entire surface. Therefore, the refrigerating compartment 11 is provided with the central passage 28a and the side passage 2
8b is uniformly cooled by cold heat uniformly discharged from a large area covering the 8b. Since the temperature detecting means 75 is not located in the member 42, the temperature detecting means 75 is hardly affected by the cold heat, and detects the temperature of the refrigerator compartment 11 more accurately.

や流量の冷気を流通させることができる。At this time, a large amount of cold heat is not transmitted to the member 42 from the cool air passing through the side passage 28b by the heat insulating member 28c. For this reason, when a lot of cool air flows into the cool air passage 27, the dew condensation of the member 42 and the discharge portion 70b is prevented, and the cold room 11
The inside can be prevented from drying. And the heat insulating member 2
By varying the area in which 8c is installed, cold air at a desired temperature and flow rate can be circulated.

In order to reduce the cooling of the member 42 by the cool air, a thin heat insulating member is provided in the central passage 28a.
May be provided on the member 42 side.

直接出ず、それらの騒音の低減がなされる。The discharge section 70b may be formed by opening the member 42, but is preferably provided around the outside of the member 42 as in the present embodiment. That is, since it does not open to the front side, firstly, the cool air passage 28 is covered and the aesthetic appearance is improved.
Secondly, since the cool air is not directly discharged to the front surface, the noise in the side passage 28b and the sound of the discharge wind at the opening 70a do not directly go out to the front, so that the noise is reduced.

できる等の効果を得ることができる。Third, since the member 42 has no opening for discharging cold air or detecting temperature, the entire surface of the member 42 contributes to uniform discharge of cold heat, and the temperature in the refrigerator becomes more uniform.
It is possible to obtain an effect that the light reflecting surface of the illumination lamp 51 or the like can be widely used without unevenness.

で若干減少し、冷蔵室１１内の温度ばらつきが生じる。The member 42 facing the central passage 28a is directly transmitted with the cold heat by the cool air, while the member 42 facing the side passage 28b is transmitted with the cold heat from the central passage 28a. For this reason, the released cold heat slightly decreases in the side passage 28b, and the temperature inside the refrigerator compartment 11 varies.

Although the temperature variation becomes larger when they are disposed on the upper surface 8a, the discharge portion 70b is disposed substantially at the center between the rib 28d forming the side wall of the central passage 28a and the side wall of the refrigerator compartment 11 in this embodiment. Accordingly, the area including the front of the side passage 28b and the vicinity of the side wall of the refrigerator compartment 11 is removed by the discharge unit 70.
Since cooling is performed with the cool air from b, the temperature variation is reduced, and cooling can be performed with more uniform discharge of cold heat.

The cool air discharge and the cold heat release of the member 42 allow the inside of the refrigerator compartment 11 to be cooled more uniformly.

By doing so, the member 42 is stored more cold by the cool heat of the cool air flowing through the cool air passage 28, and discharges as cool heat according to the temperature distribution in the refrigerator compartment 11. Therefore, the refrigerator compartment 11 is cooled uniformly.

At this time, since the cold storage member forms the inner wall of the refrigerator compartment 11, the space of the refrigerator compartment 11 can be widened, and the space of the refrigerator 1 can be saved. It is more desirable that the packaging materials 42b and 42c be made of aluminum alloy or stainless steel having thermal conductivity.

It is possible to further prevent dew condensation and icing that occurs near the vicinity, and prevent the refrigerator compartment 11 and the vegetable compartment 12 from drying.

It can be set higher than the cold air temperature. Thereby, dew condensation and icing generated on the member 42 can be further prevented.

For this reason, when the temperature and humidity in the refrigerator compartment 11 are extremely increased due to the number of times of opening and closing of the heat insulating door 3, even if dew is formed on the member 42 and water droplets are generated, they do not drop directly on the storage. Therefore, without damaging the storage,
Good storage condition can be maintained.

The inside dries. As a result, some of the water droplets evaporate while flowing down the member 42 and the back plate 35. Therefore, the humidity in the refrigerator compartment 11 can be increased again.
