In the figure, 1 is the refrigerator main body, 2 is the freezer compartment, 3 is the cooler chamber provided at the back of the freezer compartment 2, 4 is the blower installed in the cooler compartment 3, and 5 is formed on the back of the cooler compartment 3. The air path is branched into a cold room air path 5A and a chilled room air path 5B. Reference numeral 6 denotes a refrigerating room partitioned at the lower part of the freezer compartment 2, and numeral 7 represents a control room arranged at the upper rear of the refrigerating compartment 5 and communicating with the refrigerating room air passage 5A and the chilled room air passage 5B at the upper part. 6 and the air passages 5A and 5B are insulated with a heat insulating material 7a, and a temperature regulator 8 for a refrigerator room and a temperature regulator 9 for a chilled room are installed in the control room 7, and the main bodies 8a and 9a are respectively installed.
The brackets 8b and 9b are arranged so as to be on top. A middle wall 7b is provided next to the refrigerator room temperature regulator 8, and its upper end 7c is located above the baffle 8b. The air passage 7d formed by the inner wall 7b opens into the refrigerator compartment 5 and serves as a cold air outlet 7e. Reference numeral 10 denotes a chilled compartment formed in the lower part of the refrigerator compartment 6; 11 indicates an air passage formed on the back side of the refrigerator compartment 6 and communicates with the lower part of the temperature controller 9 for the chilled compartment in the control room 8 and opens into the chilled compartment 10;

The air passage device of a conventional refrigerator is configured as described above, and when the blower 4 rotates, the cold air descends through the air passage 5, but is divided into two parts in the middle, an air passage for the refrigerator compartment 5A and a chilled compartment air passage 5A. It passes through the ventilation path 5B. The cold air that has passed through the refrigerator compartment air passage 5A passes through the temperature controller 8, passes through the air passage 7d, and is blown into the refrigerator compartment 6 from the cold air outlet 7e. On the other hand, the cold air that has passed through the chilled room air passage 5B passes through the temperature regulator 9, is blown into the control room 7, is then blown out into the chilled room 10 through the air passage 11, and is further blown out from the gap 13a to the vegetables. Air is blown into the room 12.

In addition, since the upper end 7c of the inner wall 7b in FIG. 7 is located above the full height of the temperature regulator 8,
When the blower 4 is stopped, the cold air is blocked by the inner wall 7b and does not descend through the air path 7d. Therefore, if you forget to close the door, cold air will flow backwards, causing the temperature controller 8, air path 5,
This prevents condensation and freezing from touching the cooler chamber 3, etc. (hereinafter, such a configuration will be referred to as a cold air trap).

[Problem that the invention attempts to solve]

In the conventional refrigerator air path device as described above, only one cold air outlet 7e of the refrigerator compartment 6 is provided at the upper back of the refrigerator compartment 6. Cold air is difficult to reach,
Further, since the cold air outlet 7e is arranged slightly to the right of the center, there is a problem that the temperature distribution inside the refrigerator becomes uneven from side to side. Furthermore, since the cold air trap on the refrigerator compartment side is provided on the right side of the temperature controller, there is also the problem that space is required in the width direction.

This invention was made in order to solve the above-mentioned problems, and the purpose is to provide an air passage device for a refrigerator that can uniformly distribute temperature inside the refrigerator and save space in the width direction.

[Means for solving problems]

In the refrigerator air passage device according to this invention, the control room is formed over the entire height of the refrigerator compartment, and the cold air outlet to the refrigerator compartment is formed over the entire width of the control room and placed in front of the air passage for a separate room. , a plurality of traps are provided at different heights, and a cold air trap is provided below the temperature regulator for the refrigerator compartment.

[Effect]

In this invention, a plurality of cold air outlets for the refrigerator compartment are formed over the entire width of the control room and are provided over the entire height, so that the cold air is blown out from the entire surface of the refrigerator compartment. Furthermore, since the cold air trap is provided below the temperature controller, no space in the width direction is required.
