To play a role. In addition, the case 7 for small articles is located in the upper part of the case 3, and is for accommodating small storage things, such as small vegetables and small cut food. Reference numeral 8 denotes a partition wall of the case 7 for small items.
[0017]
9 is an upper partition that separates the vegetable compartment 2 from the upper storage compartment above it. In this figure, since the upper storage compartment is a refrigeration compartment with a small temperature difference from the vegetable compartment 2, The insulation layer is thinned. 10 is a wind direction board, and is located in the upper part of the cover 6. FIG. The wind direction plate 10 is attached to the cover 6 so as to be rotatable around a rotation shaft 10a with a screw after the cover 6 is assembled in the refrigerator body 1. Reference numeral 11 denotes a wind direction plate at the cold air outlet 5.
[0018]
An angle 12 is fixed to the vegetable compartment door 13 with a screw or the like, holds the case 3 and a case 7 for small items, and pulls the vegetable compartment door 13 forward, so that the case 3 and the case 7 are attached to the vegetable compartment 2. It can be pulled out from inside. 14 is an evaporator for cooling the air in the refrigerator, and 15 is a fan assembly for blowing air composed of a fan and a drive motor.
[0019]
Next, the cold air flow in the vegetable compartment 2 will be described with reference to this figure. The cold air cooled by the evaporator 14 passes through a cold air passage (not shown) in the fan assembly 15 and is fed from the cold air outlet 5 to the vegetable compartment 2. It is sent to. The cold air sent into the vegetable compartment 2 passes through the space between the cover 6 and the upper partition 9 according to the wind direction plate 10 and flows from the front to the bottom of the cover 6.
[0020]
Thereafter, the cold air passes through the space between the vegetable compartment door 13 and the case 3 and flows downward outside the case 3. The cold air that flows under the outside of the case 3 flows into a cold air return port (not shown). During this time, the cool air indirectly cools the stored items in the case 3 and the case 7 for small items.
[0021]
The passage for the cold air flow in the vegetable room 2 from the cold air outlet 5 including the cold air outlet 5 to the cold air outlet (reference numeral 21 in FIG. 3) is referred to as a vegetable room cold air passage 16. Reference numeral 17 denotes a wind direction plate spring for moving the tip of the wind direction plate 10 on the front side of the vegetable compartment 2 to the side opposite to the cold return port (reference numeral 21 in FIG. 3). Only a part of the wind direction leaf spring 17 is shown for a cross-sectional view of the main part when cut.
[0022]
The cold air flowing into the cold air return port (reference numeral 21 in FIG. 3) then returns to the lower part of the evaporator 14 through a cold air passage (not shown) leading to the evaporator 14. Since the partition 4 in the case 3 has a case 7 for small articles, it is L-shaped in order to reliably partition each room.
[0023]
In FIG. 2, arrows indicate the cold airflow on the cover 6 when each room of the vegetable room 2 is brought to a different temperature.
[0024]
The vegetable compartment door 13 is pulled forward, the case 3 and the accessory case 7 located above the case 3 are pulled out from the vegetable compartment 2 to the outside, and the partition wall 8 of the accessory case 7 is attached to a predetermined position. Thereafter, when the vegetable compartment door 13 is closed, the partition wall projection 8a provided on the partition wall 8 pushes the rotation lever 10b of the freely rotatable wind direction plate 10 so that the wind direction plate 10 rotates, as shown in FIG. In addition, a large amount of cold air flows in the direction of the low temperature room (reference numeral 3a in FIG. 3).
[0025]
Therefore, the cold air flowing out from the cold air discharge port 5 is guided to the wind direction plate 10 and the auxiliary wind direction plate 18, and the upper part of the cover 6 is located near the cold air return port (reference number 21 in FIG. 3). 3a) It flows so as to concentrate in the direction. During this time, the stored items in the case 3 and the small case 7 are indirectly cooled by the cold air through the cover 6.
[0026]
The auxiliary wind direction plate 18 is provided between the cover 6 and the upper partitioning portion 9 and is formed integrally with at least one of the cover 6 and the upper partitioning portion 9 or is attached with a separate object.
[0027]
Usually, a cool air return opening (reference numeral 21 in FIG. 3) is provided at or near the corner of the back wall of the vegetable room 2, and an independent room nearby is a low temperature room (reference numeral 3 a in FIG. 3). Is provided in the upper part of the back wall of the vegetable compartment 2, the cold air from the cold air outlet 5 flows in the direction of the cold air outlet (reference numeral 21 in FIG. 3), so that the wind direction plate 10 and the auxiliary wind direction plate 18 The position and shape are close to the cold airflow, and the shapes of the concave wind direction plate 10 and the fixed wind direction plate 18 toward the cold air return port (reference numeral 21 in FIG. 3) do not cause much vortex flow due to the cold airflow. It is a shape that not only effectively changes the direction of the wind, but also has a silent effect.
[0028]
Further, the cold air hole 6a provided in the cover 6 is located above the low temperature room (reference numeral 3a in FIG. 3) or the return side accessory room (reference numeral 7a in FIG. 3) near the front side of the cover 6 of the auxiliary wind direction plate 18 in FIG. It arrange | positions and a part of cold air by the wind direction board 10 and the auxiliary wind direction board 18 flows in the direction of the cold air hole 6a.
[0029]
Reference numeral 19 denotes a cold air hole lid that can freely open and close the cold air hole 6a, and is attached to the cover 6 so as to be movable to the left and right by a claw. Moreover, the partition protrusion part 4a provided in the partition 4 moves the cool air hole lid 19 to the side, and the cool air hole 6a is in an open state. Therefore, cold air flows into the cold room (reference numeral 3a in FIG. 3) from the cold hole 6a, keeps this room at a lower temperature, and has a cold room suitable for storing wine, beer, etc. other than vegetables in the vegetable room. A refrigerator is obtained.
[0030]
The above description is for the case where the accessory case 7 is provided in the entire lateral direction of the upper portion of the case 3. However, when the accessory case 7 is not provided, or the accessory case is located beside the upper portion of the case 3. When it is in a part of the direction, the wind direction plate 10 and the cold air hole lid 19 are operated to a partition having a shape in which the partition 4 and the partition 8 are integrated instead of the partition protrusions 4a and 8a. The same effect can be obtained even if each partition wall protrusion is provided.
[0031]
In FIG. 2, the cold air hole lid 19 is interlocked with the wind direction plate 10, and when the wind direction plate 10 faces the auxiliary wind direction plate 18, the cold air hole 6 a is opened. If the cold air hole 6a can be opened and closed independently without interlocking with the wind direction plate 10, the room below the room can be adjusted by opening and closing the cold air hole 6a with the cold air hole lid 19. It is obvious that it can be done independently.
[0032]
Further, since the cool air scooping wall 10c is provided at the end of the wind direction plate 10 on the cover 6 side in the vertical direction, leakage of cold air from the gap between the wind direction plate 10 and the cover 6 is reduced, and the cool air is efficiently guided. .
[0033]
It is obvious that if another wind direction plate is supplementarily provided on the cold air rake wall 10c of the wind direction plate 10, the cool air discharged from the cold air discharge port 5 can be more efficiently dispersed and the upper part of the cover 6 can flow.
[0034]
In addition, if a sealing material is attached to the portion of the cover 6 that faces the wind direction plate 10 at this position or a sealing wall is provided, it is possible to reliably prevent cold leakage and to guide cold air more efficiently. Is obvious. Further, the same effect can be obtained by providing the same cool air scoop wall at the end of the wind direction plate 10 on the upper partition 9 side in the up-down direction. Even if it is provided in the portion 9, the same effect is produced.
[0035]
Furthermore, 11a is a wind direction plate provided in the cold air outlet 5, and is arranged so as to direct the cold air in the direction opposite to the cold air outlet (reference numeral 21 in FIG. 3). For this reason, a part of the cold air flowing out from the cold air discharge port 5 is guided to the wind direction plate 11a, and the upper side of the cover 6 is placed on the opposite side room (see FIG. 3) opposite to the cold air return port (reference numeral 21 in FIG. 3). 3b) and in the direction of the return side accessory room (7b in FIG. 3), this room is indirectly cooled.
[0036]
Reference numeral 20 denotes a cold air escape prevention wall, which is a prevention wall useful when bringing the vegetable rooms in FIG. 4 to substantially the same temperature, and the wind direction plate 10 does not obstruct the cold air flow flowing from the cold air outlet 5. Arrangement is also taken into consideration with the movement of.
[0037]
6b and 6c are moisture permeable materials each having a property of transmitting moisture, and are integrally formed with the cover 6. When the inside of the case 3 and the case 7 for small items is high humidity, the cover 6 having the moisture permeable materials 6b and 6c is used for the case 3 and the small items in order to let the moisture pass through the moisture permeable materials 6b and 6c. By providing so as to cover the upper part of the case 7, the inside of the case 3 and the case 7 for small items can be kept at a constant humidity.
[0038]
When the moisture permeable materials 6b and 6c are provided in a place where a low-humidity gas flow such as a cold airflow is provided, the moisture permeable effect is improved. Therefore, the moisture permeable ability of the moisture permeable materials 6b and 6c and the case 3 and small objects The area of the moisture permeable materials 6b and 6c may be set in accordance with the set humidity in the case 7.
[0039]
In addition, when the moisture permeable materials 6b and 6c are detachably provided, the moisture permeable materials 6b and 6c can be easily replaced when the moisture permeable effect is lowered. In addition to the moisture permeable materials 6b and 6c, a humidity adjusting material, a member having a property of absorbing ethylene gas, a member made of an odor adsorbent such as activated carbon, a member containing an antibacterial agent, or a member provided with only a hole may be used. If the cover 6 has a shape that covers the upper portions of the case 3 and the accessory case 7, it is obvious that the cover 6 plays a role of maintaining a certain level of humidity.
[0040]
FIG. 3 is a cross-sectional view of the principal part of the BB line 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 airflow in the whole inside of the vegetable compartment 2 when it sees from the front is shown. The cold air sent to the vegetable compartment 2 through the cold air discharge port 5 flows in a distributed manner as shown by the arrow around the storage section surrounded by the cover 6 and the case 3, passes through the cold air return port 21, and the evaporator. Return to.
[0041]
During this time, the cold air flow follows the wind direction plate 10 and the auxiliary wind direction plate (reference numeral 18 in FIG. 2) so that the upper part of the cover 6 concentrates on the outer periphery of the low temperature room 3a and the return side accessory room 7a, and then the outside of the low temperature room 3a. Since it passes through the vicinity of the front and the vicinity and returns to the cool air return port 21, a lot of cool air flows around the outside of the low temperature room 3a and the return side accessory room 7a, and this part is indirectly kept at a low temperature.
[0042]
In addition, it is clear that the return side room 3b on the side of the case 3 in the opposite direction to the cold return port 21 on the side where the cold air flow is less is higher than the low temperature room 3a. Also, the return side accessory room 7a and the return side accessory room 7b in the accessory case 7 have the same tendency as described above. Here, the partition walls 4 and 8 have a double structure to increase the heat insulation effect. In some cases, a heat insulating material may be placed in the partition walls 4 and 8. Moreover, although the partition walls 4 and 8 are substantially on the same line in the vertical direction, the same effect as described above can be obtained even if they are in different positions depending on circumstances.
[0043]
In FIG. 4, an arrow indicates a cold airflow on the cover 6 when the vegetable rooms 2 are brought to substantially the same temperature.
[0044]
Pull the vegetable compartment door 13 forward, pull out the accessory case 7 located at the top of the case 3 from the vegetable compartment 2, and either remove the bulkhead 8 of the accessory case 7 or move to one of the ends of the case 7. Transfer. After that, even if the vegetable compartment door 13 is pushed in and closed, the partition wall protruding portion 8a provided on the partition wall 8 does not push the rotating lever 10b of the wind direction plate 10 which can rotate freely, so that the wind direction by the force of the wind direction plate spring 17 The plate 10 is pushed, and the wind direction plate 10 keeps rotating until it reaches 6d per wind direction plate provided on the cover 6.
[0045]
Therefore, the cold air flowing out from the cold air discharge port 5 is guided to the wind direction plate 10 and the auxiliary wind direction plate 22 and flows so as to concentrate on the upper side of the cover 6 on the opposite side to the cold air return port (reference numeral 21 in FIG. 5). During this time, the stored items in the case 3 and the accessory case 7 are indirectly cooled by the cold air through the cover 6.
[0046]
Note that if a sealing material is attached to the portion of the cover 6 that faces the wind direction plate 10 at this position or a sealing wall is provided, it is possible to reliably prevent cold leakage and guide cold air more efficiently. Is obvious. Further, if a cold rake wall similar to the cold rake wall 10 c is provided on the opposite side of the wind direction plate 10 at the end of the wind direction plate 10 on the cover 6 side, the gap between the wind direction plate 10 and the cover 6 is provided. It is clear that the cold air leakage is reduced and the cold air is efficiently guided.
[0047]
It is obvious that if another wind direction plate is supplementarily provided on the cold rake wall, the cool air discharged from the cold air discharge port 5 can be more efficiently dispersed and the upper part of the cover 6 can flow.
[0048]
Further, the same effect can be obtained by providing the same cool air scoop wall at the end of the wind direction plate 10 on the upper partition 9 side in the up-down direction. Even if it is provided in the portion 9, the same effect is produced.
[0049]
In particular, if the cold air scooping wall / seal material / seal wall is provided in the vicinity of the cold air outlet 5 where the wind direction conversion amount is large, the effect is great, and this part is close to the rotating shaft 10a, and the wind direction plate With the shape of 10, the arm portion to which the force is applied is long, and due to the lever principle, the increase in the frictional force due to the addition of the sealing material does not greatly affect the force for moving the wind direction plate 10. The spring load may be low and does not significantly affect the operation load when closing the vegetable compartment door 13.
[0050]
Further, the wind direction plate 11a provided at the cold air discharge port 5 is preliminarily set so that the cold air flows out to the side opposite to the cold air return port (reference numeral 21 in FIG. 5). It has the function of inducing cold airflow conversion when changing the airflow. Immediately after the cold air flows out from the cold air outlet 5, the cold air can be sent more efficiently to the opposite side of the cold air outlet (reference numeral 21 in FIG. 5). Therefore, it is possible to flow cold air more efficiently throughout the vegetable compartment 2.
[0051]
The cold air escape prevention wall 20 is located so as to connect between the end of the cold air outlet 5 and the end of the wind direction plate 10, and the cool air outlet (see FIG. 5 on the opposite side to the reference numeral 21). It is obvious that when a sealing material is attached to the wind direction plate 10 side of the cold air escape prevention wall 20, the prevention of cold air leakage between the cold air escape prevention wall 20 and the wind direction plate 10 is improved.
[0052]
Further, since the rotation shaft 10a of the wind direction plate 10 is located inside the end of the wind direction plate 10 and is located on the cold return port (reference numeral 21 in FIG. 5) in front of the cool air discharge port 5, the cool air is returned to the cold return port (see FIG. 5). When the wind direction plate 10 is directed as shown in FIG. 4 so as to flow in the direction opposite to the reference numeral 21) in FIG. 5, the wind direction plate 10 is cooled by the appropriate rotation of the wind direction plate 10 near the cool air discharge port 5. 5 is positioned so as to cover the entire front side with a proper interval for changing the direction of the cold air flow, and the portion of the wind direction plate 10 on the front side of the cover 6 is sufficiently on the opposite side to the cold return port (reference numeral 21 in FIG. 5). In addition to being directed and including the case where the auxiliary wind direction plate 22 is provided, the cold air outflow area in the front portion of the cover 6 can be taken to an appropriate width. Capture It can more efficiently send cold air to the opposite side of the cold air return port (reference numeral 21 in FIG. 5), therefore, can flow cold air throughout the vegetable compartment 2 in the wind direction plate 10 one.
[0053]
Further, the cool air escape prevention wall 20 provided by the relationship between the wind direction plate 10, the cool air discharge port 5 and the rotating shaft 10a is provided from the cool air discharge port 5 when each of the vegetable rooms in FIG. In order not to disturb the flowing cold airflow, the cold air discharge port 5 is opened wide, and the shape is widened away from the cold air discharge port 5.
[0054]
In addition, in FIG. 4, the partition wall 4 provided in the partition wall 4 is protruded even if the vegetable compartment door 13 is pushed in and closed because the partition wall 4 of the case 3 is removed or moved to one of both ends of the case 3. Since the portion 4a does not push the cold air hole lid 19 in the right direction, the cold air hole lid 19 is left pushed by the force of the lid spring 23, and the cold air hole lid 19 maintains the cold air hole 6a in a closed state. .
[0055]
The lid spring 23 is attached to the cover 6 with screws. Further, the cold air hole lid 19 is moved in the horizontal direction between a hook nail (reference numeral 19d in FIG. 9) of the cold air hole lid 19 to be attached to the cover 6 and a hook hole provided on the cover 6 side (reference numeral 6g in FIG. 9). The amount of movement of the cold air hole lid 19 for opening and closing the cold air hole 6a is adjusted.
[0056]
Since it is closed so that the cold air does not flow from the cold air holes 6a, there is no partial temperature drop in the vicinity of the inside of the case 3 due to the incoming cold air. In addition, the operation holes 6e and 6f for the protrusions for the partition protrusions 8a and 4a are blocked by the rotating lever 10b and the cold air hole lid 19, respectively.
[0057]
In this figure, the wind direction plate 10 and the auxiliary wind direction plate 22 are formed of continuous walls. However, a notch is provided in a part of the wall of the wind direction plate 10 and the auxiliary wind direction plate 22 so By bringing the portion toward the cold return port (reference numeral 21 in FIG. 5), the diffusion effect of the cold airflow on the cover 6 is improved, and indirect cooling to the case 3 and the case 7 in this portion is made more uniform. It is clear that it will improve.
[0058]
Further, when a notch is provided in a part of the wind direction plate 10, the influence on the cold air flow on the cover 6 in FIG. 2 is that the position of the cold air return port (reference numeral 21 in FIG. 3) is changed to the position of the auxiliary wind direction plate 18. If it is provided on the tip side (that is, the position as shown in FIG. 3), the number is small.
[0059]
FIG. 5 is a cross-sectional view of the main part of the BB line in the vicinity of the vegetable room shown in FIG. 1, but the cold airflow indicated by the arrow is the entire interior of the vegetable room 2 when the vegetable room 2 is viewed from the front. It shows the cold airflow at. The cold air sent to the vegetable compartment 2 through the cold air discharge port 5 is disposed on the upper side of the cover 6 on the opposite side of the cold air return port 21 according to the wind direction plate 10 and the auxiliary wind direction plate (reference numeral 22 in FIG. 4). Then, the air flows from the opposite side of the cold return port 21 toward the cold return port 21 through the vicinity of the outside of the case 3 and near the lower side, returns to the cold return port 21, and then evaporates from the cold return port 21. Return to the vessel.
[0060]
Therefore, cool air flows around the outside of the portion surrounded by the cover 6, the case 3, and the case 7 for small articles, and the inside of the case is indirectly cooled to a substantially similar temperature. Further, since the partition walls 4 and 8 are moved to the ends of the case 3 and the case 7 for small articles, air can be convected in the case, and the temperature in the case becomes more uniform.
[0061]
In FIG. 6, the cover 6 is provided with a step 6g and an operation hole 6e connected to the step 6g. The partition wall protruding portion 8a provided on the partition wall 8 protrudes from the operation hole 6e behind the step 6g to the upper surface of the cover 6 by closing the vegetable compartment door 13, and pushes the rotation lever 10b of the wind direction plate 10 to push the wind direction plate 10 In this case, the operating hole 6e is relatively small, and the strength of the cover 6 itself is less decreased due to the perforation of the operating hole 6e, and the operating hole 6e is blocked by the rotating lever 10b of the wind direction plate 10. The size can be small, and the operability and sealing performance of the wind direction plate 10 can be improved.
[0062]
In addition, a part of the partition protrusion 8a provided on the partition wall 8 extends away from the partition wall 8 in a substantially lateral direction (in the figure, rearward with respect to the refrigerator main body). Therefore, an operation hole provided in the cover 6 is provided. 6e becomes smaller, and when the operation hole 6e is blocked by the rotation lever 10b of the wind direction plate 10, the operability and the sealing performance of the wind direction plate 10 are further improved, and Even if the required operating range of the moving lever 10b is far behind the partition wall 8, the rotating lever 10b is surely pushed to turn the wind direction plate 10.
[0063]
FIG. 6 shows the case where the partition protrusion 8a protrudes upward with respect to the refrigerator body and extends away from the partition 8 backward, but the partition protrusion 8a protrudes in the left-right direction toward the refrigerator body. Even if it is extended rearward from the partition wall 8, it is obvious that the same effect as described above can be obtained depending on how the steps are taken.
[0064]
In FIG. 7, the vegetable compartment door 13 is pulled forward, the case 3 and the accessory case 7 located at the top of the case 3 are pulled out from the vegetable compartment 2 to the outside, and the accessory case 7 is removed from the case 3. 3 is attached to a predetermined position, and the accessory case 7 is returned to the upper part of the case 3. Then, when the vegetable compartment door 13 was pushed in and closed, the partition protrusion 4a provided in the partition 4 pushed the guide wall 19a of the cool hole cover 19, and the cold hole cover 19 moved sideways and the cold hole 6a opened. It becomes a state. That is, by closing the vegetable compartment door 13 by attaching the partition wall 4 to a predetermined position, the cold air holes 6a are opened in conjunction with each other, and the cold air flows into the low temperature room (reference numeral 3a in FIG. 3) to keep the room at a lower temperature.
[0065]
In this state, the lid spring 23 works in a direction to move the cold air hole lid 19 to the left. Reference numeral 19b denotes a lock surface of a part of the guide wall 19a, which is substantially perpendicular to the direction in which the lid spring 23 acts. Therefore, when the partition protrusion 4a is positioned on the lock surface 19b as shown in FIG. 7, the force by the lid spring 23 in the direction of pushing the partition body 4 having the partition protrusion 4a to the front of the refrigerator body 1 does not work. Thus, the force of the lid spring 23 does not work as a force in the direction of opening the vegetable compartment door 13, and the closing performance of the vegetable compartment door 13 is increased. It is obvious that if the lock surface 19b is inclined reversely with respect to the inclined surface of the guide wall 19a, the lockability is increased and the closeability of the vegetable compartment door 13 is further increased.
[0066]
In FIG. 8, the cover 6 is provided with a step 6h and an operation hole 6f connected to the step 6h. The partition wall protrusion 4a provided on the partition wall 4 protrudes from the operation hole 6f behind the step 6h to the upper surface of the cover 6 by closing the vegetable compartment door 13, and guide wall of the cold air hole lid 19 (reference numeral 19a in FIG. 7). Since the cold air hole lid 19 is moved laterally with respect to the refrigerator body 1 by pushing, the operating hole 6f is relatively small, and the strength of the cover 6 itself is less reduced by the perforation of the operating hole 6f. When the operating hole 6f is blocked by the hole lid 19, the size thereof can be reduced, and the operability and the sealing performance of the cold air hole lid 19 are improved.
[0067]
FIG. 8 shows the case where the partition protrusion 4a protrudes upward with respect to the refrigerator main body. However, even if the partition protrusion 4a protrudes leftward and rightward toward the refrigerator main body, the steps of the steps are shown. Depending on the case, it is obvious that the same effect as described above can be obtained.
[0068]
In FIG. 9, 19c is a cover hole of the cold air hole cover 19, and it overlaps with the cold air hole 6a of the cover 6, and cold air flows in this state. Reference numeral 19d denotes a hook for the cover 6, and 6g denotes a hook for the hook 19d.
[0069]
Even when a plurality of wind direction plates are provided, it is obvious that each of the above effects can be obtained more efficiently. It is also clear that if the cold air scooping wall overlaps the outside of the upper and lower walls of the cold air outlet 5, the cold air leakage is further reduced.
[0070]
【The invention's effect】
Since the refrigerator of the present invention is configured as described above,The present inventionBy setting the bulkhead to a predetermined position, the temperature of each independent room can be set to a different temperature, or by removing the bulkhead from the predetermined position, the temperature in the case can be set to almost the same temperature at any position.

In addition, the present inventionCan easily and reliably supply different amounts of cold air to various locations, and set the temperature of each room to a different temperature depending on the direction of the wind direction plate, or set the temperature in the case to almost the same temperature at any position. However, it is possible to obtain a refrigerator having a vegetable room with high practicality that can be easily and reliably selected. In addition, since the wind direction plate is located near the partition through the cover, the wind direction plate can be rotated more easily in the specified direction when the vegetable compartment door is closed by attaching and detaching the partition to the predetermined position. become able to.
[0072]
In addition, the present inventionSince the auxiliary wind direction plate is provided, even if the length of the rotating wind direction plate is short, the change in the flow rate of the cold air flowing on the cover, the case, and the periphery thereof can be wide-range, and it can be rotated. Because the length of the wind direction plate is short, the rotation range of the wind direction plate is small and the rotation load is small, and the wind direction plate can be easily and quickly rotated with a small force. Different amounts of cold air can be supplied more easily and reliably, and it is easier to set the temperature of each room to a different temperature depending on the direction of the wind direction plate, and to set the temperature in the case to almost the same temperature at any position. A refrigerator with a vegetable room rich in practicality that can be surely obtained is obtained.
[0073]
In addition, the present inventionIf the cold air holes are opened when the bulkhead is installed in place, the cold air will flow into the vegetable room that has cold holes in the cover, and this room will become even colder. A refrigerator with a cold room in the vegetable room suitable for storage of food and beer is obtained.
[0074]
In addition, the present inventionCan cut off the cool air flowing in from the operation hole, and when the temperature inside the case is set to almost the same temperature at any position, a refrigerator having a vegetable room that can keep the parts in the case at almost the same stable temperature can be obtained. .
[0075]
In addition, the present inventionThe operating hole provided in the cover is relatively small, and the decrease in strength of the cover itself due to the drilling of the operating hole is reduced. When the operating hole is blocked with a wind direction plate or a cold air hole lid, the size can be small. The operability and sealing performance of the wind direction plate or the cold hole lid are improved.
[0076]
In addition, the present inventionThe operating hole provided in the cover is smaller, and when the operating hole is covered with a wind direction plate or cold air hole lid, the size can be smaller, and the operability and sealing performance of the wind direction plate or cold air hole lid are further improved. At the same time, even if the operating part by the partition of the wind direction plate or the cold hole lid is located away from the partition, it can be reliably operated.
