FIG. 2 is a sectional view taken along line AA of the vegetable compartment 2 shown in FIG. 1. An arrow indicates a cold air flow in the humidity control cover 6 when each compartment of the vegetable compartment 2 is set to a different temperature. .

The wind direction plate 9 is arranged such that a large amount of cool air flows in the direction of a cool air return port (reference numeral 19 in FIG. 3) by operating the operation plate 11 from the front of the vegetable compartment. Therefore, the cool air flowing out of the cool air discharge port 5 is guided to the wind direction plate 9, and the upper part of the humidity control cover 6 is located near the cool air return port (reference numeral 19 in FIG. 3). Flow to concentrate in the direction. During this time, the stored items in the case 3 and the accessory case 7 are indirectly cooled by the cool air via the humidity control cover 6.

Usually, a cold air return port (reference numeral 1 in FIG. 3)
9) is provided at or near the corner of the back wall of the vegetable compartment 2 and the cool air outlet 5 is provided at the upper part of the back wall of the vegetable room 2, and the cool air coming out of the cool air outlet 5 returns to the cool air outlet ( Since it flows in the direction of reference numeral 19 in FIG. 3, the contact position and shape of the wind direction plate 9 are close to the cold air flow, and the contact position of the wind direction plate 9 concave toward the cool air return port (reference numeral 19 in FIG. 3). The shape is a shape that does not cause eddy currents due to the cool air flow, and that not only efficiently changes the wind direction, but is also good for a silent effect.

A hole 6a provided in the humidity control cover 6 is provided.
Is arranged near the front side of the humidity control cover 6 with respect to the wind direction plate 9 in FIG. 2, and a part of the cool air by the wind direction plate 9 flows in the direction of the hole 6a. Reference numeral 17 denotes a cool air hole lid capable of freely opening and closing the hole 6a, which is attached to the humidity control cover 6 so as to be movable left and right with claws.

If the cool air hole lid 17 is not linked to the wind direction plate 9 and the hole 6a can be freely opened and closed independently, the room below it can be opened and closed by the cool air hole lid 17. It is clear that the adjustment of the room temperature can also be performed independently.

Also, since the cool air rake walls 9c and 9d are provided at the vertical end of the wind direction plate 9 on the humidity control cover 6 side, the cool air leaks from the gap between the wind direction plate 9 and the humidity control cover 6. Is reduced, and cool air is efficiently guided. Further, if a sealing material is adhered to the portion of the humidity control cover 6 facing the wind direction plate 9 at this position, or if a sealing wall is provided, the cool air leakage is reliably prevented, and the cool air is more efficiently conducted. It is clear that he is. Further, the same effect can be obtained even if the same cool air rake wall is provided at the upper partition 8 at the end in the vertical direction of the wind direction plate 9, and the sealing material / seal wall is provided at the upper portion facing the corresponding position of the wind direction plate 9.

By covering the case 3 and the accessory case 7, the inside of the case 3 and the accessory case 7 can be kept at a constant humidity.

If the moisture permeable members 6b and 6c are provided in a place where a low humidity gas flow such as a cool air flow is provided, the moisture permeable effect is improved. The regions of the moisture permeable materials 6b and 6c may be set according to the set humidity in the accessory case 7. When the moisture permeable members 6b and 6c are detachably provided, the moisture permeable members 6b and 6c can be easily replaced when the moisture permeable effect is reduced.

Further, in addition to the moisture permeable materials 6b and 6c, a member having a property of absorbing ethylene gas, a member made of an odor adsorbent such as activated carbon, or a member provided only with holes may be used.
If the humidity control cover 6 has a shape that covers the upper portions of the case 3 and the accessory case 7, it is apparent that the humidity control cover 6 serves to maintain a certain level of humidity.

FIG. 3 is a cross-sectional view of a main portion taken along the line BB in the vicinity of the vegetable room shown in FIG. 1 when each room in the vegetable room is set to a different temperature. The cold air flow in the whole interior of the vegetable room 2 when the room 2 is viewed from the front is shown. The cool air sent to the vegetable compartment 2 through the cool air discharge port 5 flows around the storage section surrounded by the humidity control cover 6 and the case 3 in a dispersed manner as indicated by an arrow, and the cool air return port 19 is formed.
And return to the evaporator.

During this time, the cool air flows along the wind direction plate 9 so as to flow around the upper part of the humidity control cover 6 so as to concentrate around the outside of the return room 3a, and then passes near the front and under the outside of the return room 3a to return to the cool air. To return to the mouth 19, much cool air flows around the outside of the return side room 3a, and this part is indirectly kept at a low temperature.

It is to be noted that the opposite side of the case 3 in the opposite direction to the cool air return port 19 and the side 3 b on the opposite side of the side where the cool air flow is small.
However, it is clear that the temperature is higher than that of the return room 3a. Further, the inside of the accessory case 7 has a temperature different from that of the return side room 3a and the counter return side room 3b. Here, partition 4
Has a double structure and has a heat insulating effect. In some cases, a heat insulating material may be provided in the partition wall 4. Further, the partition wall 4 may be formed integrally with the case 3.

FIG. 4 is a sectional view of an essential part taken along line AA of the vegetable compartment 2 shown in FIG. 1. The arrows indicate the cool air flow in the humidity control cover 6 when the respective compartments of the vegetable compartment 2 are set to substantially the same temperature. To represent.

The wind direction plate 9 is arranged on the operation plate 11 so that a large amount of cool air flows in a direction opposite to the cool air return port (reference numeral 19 in FIG. 5). Reference numeral 6 d denotes a contact with the wind direction plate, and is provided on the humidity control cover 6 for positioning the wind direction plate 9. The cool air flowing out of the cool air outlet 5 is guided to the wind direction plate 9, and flows so as to concentrate on the upper side of the humidity control cover 6 toward the return room (reference numeral 3 b in FIG. 5). During this time, the stored items in the case 3 and the accessory case 7 are indirectly cooled by the cool air via the humidity control cover 6.

Since the cool air rake walls 9c and 9d are provided at the vertical end of the wind direction plate 9 on the humidity control cover 6 side, the cool air leaks from the gap between the wind direction plate 9 and the humidity control cover 6. Is reduced, and cool air is efficiently guided. Further, if a sealing material is adhered to the portion of the humidity control cover 6 facing the wind direction plate 9 at this position, or if a sealing wall is provided, the cool air leakage is reliably prevented, and the cool air is more efficiently conducted. It is clear that he is. Further, the same effect can be obtained even if the same cool air rake wall is provided at the upper partition 8 at the end in the vertical direction of the wind direction plate 9, and the sealing material / seal wall is provided at the upper portion facing the corresponding position of the wind direction plate 9. The same effect can be obtained by providing the partition portion 8.

In particular, when the above-mentioned cool air rake wall, seal material, and seal wall are provided in the vicinity of the cool air discharge port 5 where the amount of wind direction change is large, the effect is great, and this part is close to the rotating shaft 9a. If the shape of the wind direction plate 9 is used, the arm portion for applying a force is long, and the increase in frictional force due to the addition of a sealing material or the like does not significantly affect the force for moving the operation plate 11 due to the leverage principle.

Immediately after the cool air has flowed out, the cool air can be more efficiently sent to the side opposite to the cool air return port (reference numeral 19 in FIG. 5), so that the cool air can flow more efficiently through the entire vegetable compartment 2.

Further, the cool air escape preventing wall 18 is positioned so as to connect between the end of the cool air discharge port 5 and the end of the wind direction plate 9, and returns the cool air from the cool air discharge port 5 without escaping. It flows to the side opposite to the mouth (19 in FIG. 5). It should be noted that when a sealing material is adhered to the cool air escape preventing wall 18, it is apparent that the cooling air leak preventing between the cool air escape preventing wall 18 and the wind direction plate 9 is improved.

Further, since the rotation axis 9a of the wind direction plate 9 is located inside the end of the wind direction plate 9 and is located on the side of the cool air outlet (reference numeral 19 in FIG. 5) in front of the cool air discharge port 5, the cool air is cooled. When the wind direction plate 9 is directed by the movement of the operation plate 11 so as to flow to the opposite side to the return port (reference numeral 19 in FIG. 5), the wind direction plate 9 near the appropriate cool air discharge port 5 is rotated. Is positioned so as to cover the entire area in front of the cool air discharge port 5 at an appropriate interval for changing the direction of the cool air flow, and the portion of the wind direction plate 9 in front of the humidity control cover 6 is a cool air return port (reference numeral 19 in FIG. 5). And the cold air outflow area in the front part of the humidity control cover 6 can have a suitable width, so that only one wind direction plate 9 can be used.
The whole cool air coming out of the cool air discharge port 5 can be captured without difficulty, and the cool air can be sent more efficiently to the side opposite to the cool air return port (reference numeral 19 in FIG. 5).
With one piece, cool air can flow through the entire vegetable compartment 2.

Is to open the cold air discharge port 5 widely so as not to hinder the cool air flow flowing from the cool air discharge port 5 when each room of the vegetable room in FIG.
It has a shape that spreads greatly as you move away from it.

The cool rake wall 9c of the wind direction plate 9
It is obvious that if another wind direction plate is provided as an auxiliary to each 9d, the cool air coming out of the cool air discharge port 5 can be more efficiently dispersed and the upper part of the humidity control cover 6 can be flown.

In FIG. 4, the cool air hole lid 17 has the hole 6a closed so that the cool air does not flow into the return room (reference numeral 3a in FIG. 5). There is no temperature drop in this room.

FIG. 5 is a cross-sectional view of a main portion taken along the line BB in the vicinity of the vegetable room shown in FIG. 1. The cold air flow indicated by the arrow indicates that the vegetable room 2 is viewed from the front. The figure shows the cold air flow throughout the interior. The cool air sent to the vegetable compartment 2 through the cool air discharge port 5 flows around the storage section surrounded by the humidity control cover 6 and the case 3 as shown by the arrow, and the cool air return port 1

During this time, the cool air flows along the wind direction plate 9 so as to concentrate on the upper part of the humidity control cover 6 around the outside of the return side room 3b, and thereafter, the case 3 moves from the return side room 3b toward the return side room 3a. Since the air passes through the vicinity of the outside front and the vicinity below, and returns to the cool air return port 19, the cool air flows substantially similarly around the outside of the return room 3b and the return room 3a, and indirectly substantially the same in each room. Keep at temperature. If the partition 4 is removed from this portion and placed on either of the two ends of the case 3, the temperature inside the case 3 becomes more uniform.

FIG. 6 is an enlarged view of a main portion near the cool air hole cover 17 of FIG. 2. The cool air hole cover 17 is in a state where the hole 6a is opened in conjunction with the wind direction plate 9 at this position.
