Conventional Technology A conventional example will be described with reference to FIG. 1 is the refrigerator body, 2
Is a freezing room, 3 is a refrigerating room, and 4 is a third room. Reference numeral 5 denotes a cooler, which is installed on the back surface of the freezer compartment 2 and includes a blower 6 for forcedly circulating cold air through the freezer compartment 2, the refrigerating compartment 3, and the third compartment 4. Reference numeral 7 is a duct cover connected to a freezing compartment 2 and a duct 8 for dividing the cold air into the refrigerating compartment 3 and the third compartment 4, and the duct 8 is connected to a temperature control device 9 of the refrigerating compartment 3 and the third compartment 4. is doing. The temperature control device 9 has a damper opening / closing device for adjusting the amount of cold air discharged to the refrigerating chamber 3 and a cool air discharge passage to the refrigerating chamber 3 (both not shown) and discharges cool air to the third chamber 4. A damper opening / closing device 10 for adjusting the amount, a temperature sensing portion 11 of the damper opening / closing device 10, and a cool air discharge passage 1 to the third chamber 4.
2. It has a cold air outlet 13. On the other hand, the partition wall 14 is provided with a cool air return passage 15 to the refrigerating chamber 3 and a cool air return passage 16 of the third chamber 4 connected to the return passage 15. Further, the third chamber 4 is substantially sealed by a partition wall 14 at the ceiling surface, a wall surface of the temperature control device 9 at the back surface, a door 17, and a second partition wall 18 at the bottom surface.

In such a configuration, the air cooled by the cooler 5 flows into the freezer compartment 2 by the blower 6 through the discharge port 7 ′ of the duct cover 7 and is forcedly circulated, and also through the duct 8 to the temperature control device 9. The amount of cold air is controlled to a desired temperature by a damper opening / closing device (not shown) for the refrigerating chamber and a damper opening / closing device 10 for the third chamber, respectively, and a cooler is provided via each discharge passage and return passage. After returning to 5, the same operation is continued and cooling is performed. Incidentally, here, the third chamber 4
Is set in a temperature range (for example, 0 to 3 ° C) lower than the normal refrigeration temperature (0 to 10 ° C), and stores fresh foods such as fish and meat that require stable low temperature storage to maintain freshness. Often provided in a dedicated low temperature room.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the air passage structure of the third chamber 4 among the above-described structures, the cool air discharge port 13 of the temperature control device 11 has two or more
Cold air discharge port 13 when used because there are only 3 places
If food is stored in an arrangement that obstructs the front of
Since the flow of the discharged cool air is obstructed, the temperature of the entire third chamber 4 becomes high, and conversely, the food immediately before the cool air discharge port 13 may be frozen. It has been a problem in use for fresh foods that require storage in the low temperature zone. On the other hand, in the third chamber 9, the upper part is the freezing chamber 2, the lower part is the refrigerating chamber 3, and the rear part is the duct 8
In this way, the three sides are surrounded by low temperature parts other than the outside air, and the amount of heat absorption load into the room is small due to the arrangement structure, and the purpose can be achieved with a small amount of cooling for the room cooling.
It does not require the active introduction of discharged cold air, especially in the rear of the center of the room, it is indirectly cooled by a duct maintained at a low temperature, and it is not easily affected by the heat absorbed by the outside air from the door 17 part. Because the indoor structure is relatively low and the depth is deeper than that, it is not easily affected by outside air intrusion when opening and closing the door 17 during actual use. It strongly includes an element showing a distribution of a lower temperature than that in the vicinity of 17, and since the cool air discharge port 13 is provided on the temperature adjusting device 9 at the rear of the room, it becomes easier to cool the rear of the room, and However, there was a problem that the temperature unevenness of the above was further expanded.

The present invention solves the above-mentioned conventional problems, and an object of the present invention is to provide a structure of a cold air discharge port which is not disturbed by food and has less temperature unevenness.

Means for Solving the Problems In order to solve the above problems, the present invention provides a plurality of cool air discharge holes by providing a cool air introduction passage connected to a cool air discharge passage of a temperature control device of a third chamber in a partition wall. And a case frame that forms a cold air discharge passage communicating with the cold air introduction passage is arranged around the front surface of the third chamber.

Action The present invention has the above-described configuration, there is almost no risk that the cold air discharge port is obstructed by food or the like, the cool air is discharged from the cool air discharge hole in the upper part of the case frame toward the front of the third room, and The temperature unevenness can be reduced.

EXAMPLES Examples of the present invention will be described below with reference to FIGS. In addition, the same reference numerals are given to the same components as the conventional one,
Only different parts will be described.

In FIGS. 1 and 2, 19 is a third chamber cool air discharge passage
It is a cold air introduction passage connected to 12 and provided in the partition wall 14 to the third chamber 4. Further, a case frame 20 facing the door 17 is provided around the front surface of the third chamber 4, and a plurality of cool air discharge holes 21 are provided at the upper portion of the case frame 20. A cold air discharge passage 23 communicating with each other is formed.

With such a configuration, the cool air controlled in an appropriate amount by the damper opening / closing device 10 is guided to the cool air discharge passage 23 through the cool air discharge passage 12 and the cool air introduction passage 19, and the plurality of cool air discharge holes 21 dispersedly arranged in appropriate places. Since the cool air is supplied mainly to the inside of the third chamber 4 inside the room, temperature unevenness and local freezing due to food arrangement can be prevented, and at the same time, the inside of the inside of the room shows a higher temperature than the inside of the room. It is possible to perform Hashimasa due to uneven temperature.
