Description

  The present invention relates to a refrigerator.

  A conventional refrigerator is disclosed in Patent Document 1. This refrigerator includes a storage room and a cooling room provided behind the storage room with a wall surface therebetween. The refrigerator has an opening on the front surface, a door that closes the opening so that it can be opened and closed, and a storage case that is arranged inside the storage room and slides back and forth. The cooling chamber includes a cooler and a fan. An outlet is provided on the wall surface for blowing cool air cooled by the cooler and sent by the fan into the storage chamber.

  The outlet protrudes into the storage chamber. When the storage case is stored in the storage room, the tip of the outlet is inserted into the storage case. With this configuration, the cool air blown out from the outlet can reliably flow into the storage case.

JP-A-7-55321

  In the refrigerator as described above, when the storage case is pulled out from the opening to the outside, when taking out, storing, and organizing articles, air having a higher temperature than the air inside the storage room flows in from the outside. . In the storage room, the temperature is low because the wall surface is adjacent to the cooling room. When hot air comes into contact with the wall surface, water vapor condenses, and water droplets adhere to the wall surface.

  The dew water flows downward. In the refrigerator of Patent Literature 1, since the outlet protrudes from the wall surface, dew condensation water accumulates on the upper part of the outlet. When the storage case is stored in the storage room, the tip of the air outlet is inserted into the storage case, so that the dew condensation water may flow into the storage case. When the dew water flows into the storage case, the dew water is applied to the articles stored in the storage case and wets the articles. Some of the above-mentioned articles need to be stored dry, and there is a risk that the articles may be soiled or damaged. In addition, since the dew condensation water may contain foreign matters such as dust and other germs contained in the external air, if the dew condensation water accumulates in the storage container, there may be a problem in hygiene.

  Therefore, an object of the present invention is to provide a refrigerator capable of suppressing entry of a dew condensation water into a storage room for storing articles and efficiently cooling the storage room.

  In order to achieve the above object, the present invention provides a storage member capable of storing articles slidably received in a storage chamber in a front-rear direction, and a cold air duct disposed across a rear wall of the storage chamber. A discharge hole that is provided in the rear wall and communicates with the cool air duct; and a cool air guide member that is provided at a rear end of the storage member and extends rearward, wherein the storage member is stored in the storage chamber. When provided, a refrigerator is provided in which a rear end of the cool air guiding member is close to a periphery of the discharge hole of the rear wall.

  According to this configuration, since the cool air guiding member is provided at the rear end of the storage member, all or substantially all of the cool air discharged from the discharge holes can be guided to the storage member. Thereby, it is possible to effectively cool the articles stored in the storage member. Further, since the rear end of the cool air guide member is close to the periphery of the discharge hole of the rear wall, the dew condensation water generated on the rear wall is prevented from flowing into the storage member. Thereby, it is possible to suppress the wetness of the stored articles and to prevent the dew condensation water from adhering, so that the sanitary condition inside the storage member can be kept good.

  In the above configuration, the refrigerator may be provided with a rib protruding forward from an edge of the discharge hole. With such a configuration, the edge of the ejection hole can be rounded. Thus, it is possible to prevent the finger of the user or the operator, the stored articles, and the like from being damaged. In addition, it is possible to suppress a decrease in freshness and a decrease in quality due to damage to stored articles.

  In the above configuration, in the refrigerator, a rear end of the cold air guiding member may be close to a position below the discharge hole of the rear wall when the storage member moves rearward. With this configuration, when the flow velocity of the cool air flowing out of the discharge hole is low, the cool air flowing out of the discharge hole immediately flows downward. Since the cool air guide member is provided below, much cool air can be guided to the storage member.

  In the above configuration, in the refrigerator, a rear end of the cold air guiding member may have flexibility. With this configuration, even if the cold air guide member and the rear wall come into contact with each other due to the temperature change of the cool air guide member and the rear wall, the cool air guide member is deformed, so that the housing member is not deformed. Slides are not easily disturbed. Thereby, it can suppress that a storage room becomes a poor sealing. Further, even if the cold air guiding member and the rear wall come into contact with each other, the member is hardly damaged. Thereby, even if the proximity distance (gap) to the rear wall of the cool air guide member is reduced, no trouble is likely to occur. This allows more cold air to flow into the storage member.

  In the above-described configuration, in the refrigerator, the cold air guide member may include a water guiding unit that causes the water flowing into the upper part to flow downward. In addition, as a water guide part, the drainage hole which penetrated up and down, the unevenness | corrugation inclined with respect to the direction orthogonal to the moving direction of a storage member, etc. can be mentioned. Thereby, the inflow of dew condensation water into the storage member is suppressed.

  In the above configuration, in the refrigerator, the cold air guiding member may have a cylindrical shape. With this configuration, even when the cool air blown out from the discharge holes is directed horizontally or upward and the flow velocity is high, the cool air can be reliably guided to the storage member.

  In the above configuration, the refrigerator has a brim portion extending from below the discharge hole, and the cold air guiding member has an upper surface facing the brim portion when the storage member is stored in the storage room. And a side wall extending from the end of the upper surface in a direction orthogonal to the front-rear direction toward the collar. With this configuration, when the storage member is stored in the storage room, the cool air guiding member has a cylindrical shape, so that the cool air can be reliably flowed into the storage member. Further, since the cold air guiding member has a shape without a bottom surface, the shape of a mold for molding is simple, and the manufacturing cost can be reduced.

  In the above configuration, in the refrigerator, the storage member may include a frame and a storage case supported by the frame, and the cool air guide member may be provided in the storage case.

  In the above configuration, in the refrigerator, the storage member may include a frame and a storage case supported by the frame, and the cool air guide member may be provided in the frame. With this configuration, the shape of the storage case can be made simple. Thereby, at the time of maintenance such as cleaning, repair, and inspection, the storage case can be easily removed, and workability can be improved.

 ADVANTAGE OF THE INVENTION According to this invention, a refrigerator provided with the door which can suppress deformation | transformation and breakage and can suppress the fall of cooling performance by deformation | transformation of a frame can be provided.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(1st Embodiment)
FIG. 1 is a front view of an example of a refrigerator according to the present invention. In the following description, the directions such as the front-back direction, the up-down direction, and the left-right direction may be indicated. In this case, the state illustrated in FIG. The refrigerator Rf has a heat insulating box 100 filled with a foamed heat insulating material. In the refrigerator Rf, the inside of the heat-insulating box 100 is partitioned by a partition wall to form a plurality of storage rooms. A partition wall 101 for vertically dividing the inside of the heat insulating box 100 is provided at an intermediate portion in the vertical direction. Further, a partition wall 102 for dividing the inside of the lower space into upper and lower parts is provided. Further, a partition wall 103 that divides an upper space partitioned by the partition wall 102 into right and left is provided. Further, a partition wall 104 for vertically dividing the left space partitioned by the partition wall 103 is provided.

  The storage room formed above the partition wall 101 among the plurality of storage rooms of the refrigerator Rf is the refrigerator room 1. The storage room formed below the partition wall 102 is the lower freezing room 2. The upper storage room on the left side of the space partitioned by the partition wall 103 is the ice making room 4 (ice storage section), and the lower storage room is the upper freezing room 3. The storage room on the right side of the ice making room 4 and the upper freezing room 3 is a vegetable room 5. A machine room 10 is provided at a lower rear portion of the lower freezing compartment 2. Inside the machine room 10, a compressor 12 for operating a refrigeration cycle is installed.

  The refrigerator room, the lower freezer room, the upper freezer room, the ice making room, and the vegetable room need not be arranged in this manner, and may be changeable in accordance with the frequency of use, the amount of storage, and the like. Moreover, you may provide the storage room which stores a storage thing in temperature other than these storage rooms.

  The lower freezer compartment 2 and the upper freezer compartment 3 are storage compartments for storing and storing the stored products in a frozen state (for example, at -18 ° C). The ice making room 4 is a storage room for storing ice produced by an ice making device (not shown), and is maintained at the same temperature as the upper freezing room 3 and the lower freezing room 2.

  In the refrigerator Rf, the lower freezing compartment 2, the upper freezing compartment 3, and the ice making compartment 4 form one integrated heat insulating area. As shown in FIG. 2, an opening 105 is provided in the partition wall 102. The upper freezer compartment 3 and the lower freezer compartment 2 are communicated via the opening 105. Similarly, an opening 106 is provided in the partition wall 104. The ice making room 4 and the upper freezing room 3 communicate with each other through the opening 106.

  Then, the refrigerator compartment 1 refrigerates and stores the stored material at a higher temperature (for example, 3 ° C. to 5 ° C.) than the lower freezer compartment 2 and the upper freezer compartment 3, and the vegetable compartment 5 has a higher temperature (for example, the refrigerator compartment 1). (7 ° C. to 8 ° C.) and refrigerate storage of vegetables and the like. In addition, the temperature of each storage room is not limited to this, and is set to a temperature that can suppress deterioration of articles stored in each storage room. Further, the user may be able to set the temperature as needed or as desired.

  The refrigerator compartment 1 is opened and closed by a pair of double doors 11 which are pivotally supported at left and right ends. The lower freezing compartment 2, the upper freezing compartment 3, and the ice making compartment 4 are provided with storage cases 22, 32 and 42, respectively. The storage cases 22, 32 and 42 are slid back and forth as the drawer-type doors 21, 31 and 41 are opened and closed. The vegetable compartment 5 includes a storage case 52 and is slid back and forth with opening and closing of a drawer-type door (not shown).

  The refrigerator Rf includes a cool air passage 6 and a cool air passage 7 that communicate with each other via a damper 71 at a rear portion. The cold air passage 6 is provided behind the lower freezing compartment 2, the upper freezing compartment 3, and the ice making compartment 4. Further, the cold air flow path 7 is provided behind the refrigerator compartment 1.

  In the cool air passage 6 and the cool air flow passage 7, a freezing room fan 61 and a refrigerating room fan 72 for circulating cool air are arranged, respectively. An evaporator 62 for generating cool air is disposed below the freezer compartment fan 61. Below the evaporator 62, a defrost heater 63 for removing (defrosting) frost attached to the evaporator 62 is arranged. As shown in FIG. 2, a partition 107 is provided as a rear wall behind the lower freezing compartment 2, the upper freezing compartment 3, and the ice making compartment 4. The lower freezing compartment 2, the upper freezing compartment 3, and the ice making compartment 4 are adjacent to the cold air passage 6 with the partition wall 107 interposed therebetween.

  The partition 107 has discharge holes 601, 602, and 603, which are openings for discharging cool air. In addition, a return port 604, which is an opening through which cool air returns, is formed in the partition wall 107. The cool air blown out from the discharge holes 601, 602, and 603 cools the lower freezing room 2, the upper freezing room 3, and the ice making room 4, respectively, and returns to the cool air passage 6 from the return port 604. The cold air passage 6 is provided with a partition member 600 that divides the cold air passage 6 back and forth.

  The front part of the cool air passage 6 partitioned by the partition member 600 is a cool air duct 605 for guiding cool air to the discharge holes 601, 602, and 603. The partition member 600 is in contact with the partition 107 at the lower part. The rear part partitioned by the partition member 600 is a cool air generation flow path 606. The cool air duct 605 and the cool air generation flow path 606 communicate with each other at the upper part.

  In the cool air generation flow path 606, a freezing room fan 61 and an evaporator 62 are arranged. That is, the cool air generated in the cool air generation flow path 606 turns back at the upper part and flows into the cool air flow path 605. Then, it passes through the cool air flow path 60 and flows into the lower freezing chamber 2, the upper freezing chamber 3, and the ice making chamber 4 from the discharge holes 601, 602, and 603. In addition, the return port 604 is in direct communication with the cool air generation channel 606, and the air returning from the return port 604 directly flows into the cool air generation channel 606.

  In addition, a partition 108 is provided behind the refrigerator compartment 1. The refrigerator compartment 1 is adjacent to the cold air flow path 7 with the partition wall 108 interposed therebetween. The cool air passage 7 communicates with the cool air passage 6 via a damper 71. When cooling the refrigerator compartment 1, the damper 71 is opened, and the cool air in the cool air passage 6 flows into the cool air passage 7. Note that a cooling fan 72 is provided inside the cool air passage 7, and the cool air flowing from the damper 71 flows through the cool air passage 7 by the cooling fan 72.

  The partition 108 has a plurality of discharge holes 701 which are openings for discharging cool air into the refrigerator compartment. The plurality of discharge holes 701 discharge cool air to respective stages partitioned by shelves of the refrigerator compartment 1. The partition wall 101 is provided with a communication path 702 that connects the refrigerator compartment 1 and the vegetable compartment 5. Note that the temperature of the cold air is raised to remove heat from the stored material when flowing through the refrigerator compartment 1. Then, the heated cool air flows into the vegetable compartment 5 from the communication passage 702. Therefore, the vegetable room 5 is maintained at a higher temperature than the refrigerator room 1. The cool air flowing through the vegetable compartment 5 returns to the cool air flow path 6 via a return port (not shown). The return port is provided on the lower side and the back side of the vegetable compartment 5.

  As described above, in the refrigerator Rf according to the present invention, the cool air in the cool air passage 6 is discharged from the discharge holes 601, 602, and 603 provided in the partition wall 107, and the lower freezing compartment 2, the upper freezing compartment 3, and the ice making The chamber 4 is cooled. The cool air in the cool air passage 7 is discharged from the discharge holes 701 provided in the partition wall 108 to cool the refrigerator compartment 1.

(1st Embodiment)
In the lower freezer compartment 2 and the upper freezer compartment 3, articles are placed in the storage cases 22 and 32. Then, the storage cases 22 and 32 are slid back and forth together with the doors 21 and 31 to open and close. The ice making chamber 4 stores ice produced by the refrigerator Rf, but has the same basic configuration as the lower freezing compartment 2 and the upper freezing compartment 3.

  The features of the configuration of such a drawer-type storage room will be described with reference to the drawings. The lower freezing compartment 2, the upper freezing compartment 3, and the ice making compartment 4 have substantially the same configuration. Therefore, in the following description, the characteristics will be described with the lower freezing compartment 2 as a representative. FIG. 3 is a sectional view of a drawer type storage room of the refrigerator according to the present invention, and FIG. 4 is a schematic layout diagram showing a closed state of the storage room shown in FIG.

  As described above, the drawer-type storage room shown in FIG. In the lower freezer compartment 2, a storage case 22 is stored in a rectangular parallelepiped storage space 20, which is a storage room, so as to be movable back and forth. The storage case 22 moves integrally with the door 21. The lower freezer compartment 2 includes a frame 23 that supports a door 21 and a storage case 22. In the lower freezer compartment 2, the door 21, the storage case 22, and the frame 23 move back and forth. Therefore, the door 21, the storage case 22, and the frame 23 are storage members.

  The frame 23 includes a side support rail 230, a connecting member 231, and a guide roller 232. The side support rail 230 is a beam-shaped member extending in the front-rear direction, and is provided in parallel to the left and right. That is, the frame 23 includes a pair of side support rails 230. The front end of the side support rail 230 is fixed to the door 21. A connecting member 231 for connecting the side support rails 230 is provided at the rear ends of the pair of side support rails 230. Here, the connection member 231 is a beam-shaped member extending in the left-right direction. A guide roller 232 is provided behind the lower surface of the side support rail 230.

  A pair of guide rails 24 extending in the front-rear direction is provided on the inner surface of the storage space 20, that is, on the side surface of the heat insulating box 100. The pair of guide rails 24 extend in parallel with the side support rails 230. A guide roller 241 is provided at the front of the upper surface of the pair of guide rails 24.

  In the lower freezer compartment 2, the guide roller 241 supports the lower surface of the side support rail 230 and rolls with respect to the side support rail 230. The guide roller 232 rolls on the upper surface of the guide rail 24. The frame 23 is moved back and forth by the guide rollers 232 and 241 with a small force. In addition, the lower freezing compartment 2 has a closing mechanism that generates a force to move rearward by using its own weight when the door 21 and the storage case 22 move rearward. With this closing mechanism, the door 21 is securely closed. Further, the structure of the lower freezing compartment 2 is not limited to this configuration, and a configuration that supports the door 21 and the storage case 22 movably back and forth can be widely adopted.

  As described above, when the storage case 22 is stored in the storage space 20, if the rear end of the storage case 22 contacts the partition 107, the lower freezing compartment 2 may be insufficiently sealed. In addition, due to the action of the above-described closing mechanism, the storage case 22 may be pushed backward even when the rear end of the storage case 22 is in contact with the partition 107. In this case, the storage case 22 may be damaged, and the partition 107 may be damaged. Therefore, when the storage case 22 is stored in the storage space 20, the storage case 22 does not contact the partition 107. That is, when the storage case 22 is in the storage state, a gap is formed between the rear end of the storage case 22 and the partition 107.

  As described above, the partition 107 is provided with the discharge hole 601, and the cool air discharged from the discharge hole 601 cools the article inside the storage case 22. Therefore, it is preferable that the cool air discharged from the discharge holes 601 flow into the storage case 22 as much as possible. Therefore, a cool air guiding member 81 is provided at the rear end of the storage case 22.

  As shown in FIGS. 3 and 4, the cool air guide member 81 is a plate-like member extending rearward from the rear end of the upper surface of the storage case 22. The cool air guide member 81 is inclined rearward, and the rear is higher than the front. Then, the rear end of the cool air guide member 81 faces the lower side of the discharge hole 601. When the storage case 22 is stored in the storage space 20 and the door 21 is closed, a gap is formed between the rear end of the cool air guiding member 81 and the partition 107.

  As described above, the cool air flowing through the cool air duct 605 is discharged from the discharge hole 601. Since the cool air has a lower temperature than the surrounding air, it tends to flow downward. A cool air guide member 81 is provided in front of the partition 107, that is, below the discharge holes 601 on the cool air discharge side. Therefore, the cool air flowing downward is guided by the cool air guide member 81 and flows into the storage case 22. By providing the cool air guide member 81 in the storage case 22, all or substantially all of the cool air discharged from the discharge holes 601 can flow into the storage case 22. Thereby, a decrease in cooling efficiency can be suppressed.

  The cool air flowing through the cool air duct 605 is cool air discharged from the freezer compartment fan 61 and flows at a certain flow rate. The cool air discharged from the discharge hole 601 has a velocity component orthogonal to the partition 107. Therefore, the cool air discharged from the discharge hole 601 has a velocity in a direction away from the partition 107, and even if there is a gap between the cool air guide member 81 and the partition 107 immediately below the discharge hole 601, Few or very little cool air leaks downward from the gap. In other words, in a configuration in which forced air is blown using the freezing room fan 61, even if there is a gap between the partition 107 around the discharge hole 601 and the cool air induction member 81, the cooling efficiency does not decrease, or even if it decreases. It is minute.

  In the lower freezer compartment 2, the door 21 is opened and closed when articles are taken in and out. At this time, external high-temperature air flows into the storage space 20. Since the partition wall 107 is also cooled in the lower freezing compartment 2, moisture contained in the external high-temperature air condenses. Then, the dew water flows downward along the partition 107. In the lower freezing compartment 2 of the present embodiment, the condensed water drops flow below the partition 107 through a gap between the rear end of the cool air guide member 81 and the partition 107. That is, the condensed water that has flowed downward does not flow into the cool air guide member 81 but flows through the partition 107 as it is. Therefore, it is possible to prevent the dew water from flowing into the storage case 22.

  In the lower-stage freezer 2, there are cases in which articles such as medicines and foods that cannot be wetted with water are stored and stored. In addition, the dew condensation water may contain dust and the like, and may contain microorganisms. May not be preferred. By providing the cool air guide member 81, the stored articles can be cooled, and the adhesion of the dew condensation water to the stored articles can be suppressed, and the above-described problems can be suppressed.

  Further, even if there is no problem with the dew water, some users may feel uncomfortable that the dew water is attached to the storage case 22. By providing the cool air guide member 81, the inflow of dew condensation water into the storage case 22 is suppressed, so that the user can be prevented from feeling uncomfortable.

  In addition, it is preferable that the gap between the cold air guide member 81 and the partition 107 is a distance through which dewed water can pass. Further, a container for storing dew condensation water may be provided below the cool air guide member 81. In the present embodiment, the cool air guide member 81 is formed as the same member as the storage case 22. This simplifies manufacturing. However, the present invention is not limited to this, and the storage case 22 and the cool air guide member 81 may be combined as separate members.

(Modification 1)
Another example of the drawer type storage room of the present embodiment will be described with reference to the drawings. FIG. 5 is a sectional view of another example of the drawer-type storage room of the refrigerator according to the present invention, and FIG. 6 is a schematic layout diagram showing a closed state of the storage room shown in FIG.

  The above-described cold air guide member 81 is manufactured as the same member as the storage case 22, and is formed as a member having the same hardness as the storage case 22. Even if the partition wall 107 and the cold air guide member 81 are formed of the same material, there may be a difference in deformation due to heat depending on the amount of circulating cool air and the temperature at that time. For this reason, when the gap between the cool air guide member 81 and the partition 107 is designed as a gap through which water can pass, if there is a difference in deformation between the cool air guide member 81 and the partition 107, the cool air guide member 81 and the partition 107 come into contact with each other. However, the door 21 is not securely tightened and there is no poor sealing, or the cold air guiding member 81 or the partition 107 is damaged.

  In order to eliminate such a problem caused by the contact between the cool air guide member 81 and the partition wall 107, in the lower freezer compartment 2 shown in FIGS. The elastic member 811 having the property is attached. By attaching the elastic member 811, the elastic member 811 is deformed by coming into contact with the partition 107 even if the distance between the cold air guiding member 81 and the partition 107 is smaller than a design value due to a difference in thermal deformation. For this reason, it is possible to suppress breakage of the cool air guiding member 81 and the partition 107 and poor sealing of the door 21.

  In addition, even if the elastic member 811 and the partition 107 come into contact with each other, a trouble hardly occurs. Therefore, the gap between the elastic member 811, that is, the cool air guiding member 81 and the partition 107 can be reduced. Thus, the amount of cool air flowing downward from the gap between the cool air guide member 81 and the partition 107 can be reduced, so that more cool air can be guided to the storage case 22. Note that the rear end of the cool air guide member 81 may have flexibility, or the entire cool air guide member 81 may have flexibility.

(Modification 2)
Another example of the drawer type storage room of the present embodiment will be described with reference to the drawings. 7 is a cross-sectional view of another example of the drawer-type storage room of the refrigerator according to the present invention, and FIG. 8 is a schematic layout diagram illustrating a closed state of the storage room illustrated in FIG.

  In the above-described lower freezing compartment 2, a cool air guide member 81 is provided at the rear end of the storage case 2. However, it is not limited to this. The cool air guide member 81 may be provided at the rear end of the storage member including the storage case 2. For example, as in the lower freezer compartment 2 shown in FIGS. 7 and 8, the cool air guiding member 81 is provided on the connecting member 231. That is, the cool air guide member 81 is provided at the rear end of the storage member including the door 21, the storage case 22, and the frame 23, and extends rearward.

  With such a configuration, since the cool air guide member 81 is not attached to the storage case 21, it is possible to easily attach and detach the storage case 21 when performing maintenance such as cleaning and repair.

(2nd Embodiment)
A drawer-type storage room according to the present invention will be described with reference to the drawings. As in the first embodiment, the features will be described with the lower freezing compartment 2 as a representative. 9 is a cross-sectional view of another example of the drawer-type storage room of the refrigerator according to the present invention, and FIG. 10 is a schematic layout diagram illustrating a closed state of the storage room illustrated in FIG. In the lower freezing compartment 2A of the present embodiment, a rib 82 protruding forward is provided around the outlet hole 601. Other features are the same as those of the lower freezing compartment 2 of the first embodiment, and substantially the same portions are denoted by the same reference characters, and detailed description of the same portions will be omitted.

  As shown in FIGS. 9 and 10, a rib 82 extending forward from the edge of the discharge hole 601 of the partition 107 is provided. The rib 82 has a tubular shape with a rectangular cross section. When the door 21 is closed, the front end of the rib 82 is located behind the rear end of the cool air guiding member 81, that is, on the back side of the storage space 20.

  The provision of the rib 82 can prevent a user or an operator from sharpening the edge of the discharge hole 601. Accordingly, it is possible to prevent the edge of the discharge hole 601 from being damaged even when the user or the operator touches the hand or the stored article touches the edge.

  Further, a rib 82 is provided at an edge of the discharge hole 601, and water accumulates in the rib 82. Then, the water accumulated in the rib 82 flows along the rib 82 and flows downward from the left and right ends of the rib 82. Therefore, it is possible to suppress the dew water flowing down the partition 107 from flowing into the discharge holes 601. Further, since the dew water flows in the right and left directions by the ribs 82, the flow of the dew water to the cool air guide member 81 is also suppressed. The protruding height of the rib 82 may be, for example, about 2 mm to 3 mm, but is not limited thereto.

  Other features are the same as in the first embodiment.

(Third embodiment)
A drawer-type storage room according to the present invention will be described with reference to the drawings. As in the first embodiment, the features will be described with the lower freezing compartment 2 as a representative. FIG. 11 is a sectional view of still another example of the drawer-type storage room of the refrigerator according to the present invention. The lower freezing compartment 2B of the present embodiment is characterized in that a cool air guide member 83 is provided at the rear end of the storage case 22. Other features are the same as those of the lower freezing compartment 2 of the first embodiment, and substantially the same portions are denoted by the same reference characters, and detailed description of the same portions will be omitted.

  The cool air guide member 83 provided in the lower freezing compartment 2B shown in FIG. 11 includes a plurality of drainage holes 831 penetrating from the upper surface to the lower surface. The drainage hole 831 is a water guide for flowing the water flowing into the upper part of the cool air guide member 83 downward.

  Similar to the cool air guide member 81 provided in the lower freezing compartment 2, the cool air guide member 83 is provided with a gap through which dew condensation water can pass between the partition 107 and the cool air guide member 81. However, when the door 21 is closed, the cool air guide member 83 itself is also cooled, and when high temperature air flows in by opening and closing the door 21, dew may be formed on the cool air guide member 83 itself. In addition, there may be a case where dew condensation water more than expected adheres due to a change in external temperature or humidity. In this case, the water flowing down the partition 107 may flow toward the cool air guide member 83 in some cases.

  As described above, when the dew water flows through the cool air guide member 83, it flows through the drain hole 831 and below the cool air guide member 83. Therefore, the inflow of dew condensation water into the storage case 22 can be suppressed.

  Other features are the same as those of the first embodiment and the second embodiment. In addition, a convex portion for suppressing dew condensation water from flowing into the storage case 22 may be provided at a connection portion between the cool air guide member 83 and the storage case 22.

(Modification)
FIG. 12 is a schematic layout view of still another example of the drawer-type storage room of the refrigerator according to the present invention. On the upper surface of the cool air guide member 83 of the lower freezing compartment 2B2 shown in FIG. 12, unevenness 832 inclined left and right is provided. The water on the upper surface of the cool air guide member 83 is blocked by the unevenness 832, and the flow into the storage case 22 is restricted. The unevenness 832 is inclined forward, that is, rightward downward. For this reason, even if an amount of water that flows on or adheres to the upper surface of the cool air guide member 83 flows into or adheres to the upper surface, the water flows along the irregularities 832 and flows downward from the right end of the cool air guide member 83. Thus, the inflow of water into the storage case 22 can be suppressed. In addition, the unevenness 832 is a water guide part. Further, the drain hole 831 may be used in combination.

(Fourth embodiment)
A drawer-type storage room according to the present invention will be described with reference to the drawings. As in the first embodiment, the features will be described with the lower freezing compartment 2 as a representative. FIG. 13 is a sectional view of still another example of the drawer-type storage room of the refrigerator according to the present invention. FIG. 14 is a schematic layout diagram showing a closed state of the storage chamber shown in FIG. In the lower freezer compartment 2C of the present embodiment, a cool air guide member 84 is provided at the rear end of the storage case 22. Other features are the same as those of the lower freezing compartment 2 of the first embodiment, and substantially the same portions are denoted by the same reference characters, and detailed description of the same portions will be omitted.

  As shown in FIGS. 13 and 14, the cool air guide member 84 has a tubular shape that penetrates back and forth. The cool air guide member 84 is inclined, and the rear portion is higher than the front portion. The cool air guide member 84 has an inlet opening 841 through which cool air flows into the rear end, and an outlet opening 842 through which cool air flows out into the storage case 22 at the front end. The inflow opening 841 has a rectangular shape larger than the discharge hole 601, and when the door 21 is closed, the inflow opening 841 comes close to the periphery of the discharge hole 601 before and after.

  When the flow rate of the cool air flowing out of the discharge hole 601 is low, all or almost all of the cool air can flow into the storage case 22 by the plate-like cool air guide member 81 provided below the discharge hole 601. . However, when the speed of the cool air discharged from the discharge hole 601 is high, a fast airflow is blown out from the discharge hole 601 in the horizontal direction. Further, depending on the shape of the discharge hole 601 and the shape of the cool air duct 605, cool air may be blown upward from horizontal. When the cool air is blown in such a blowing direction, the cool air may be blown to the same place in the storage case 22 and the cooling efficiency may be reduced.

  Therefore, by providing the cylindrical cool air guide member 84, cool air blown horizontally or upward is forcibly rectified toward the storage case 22. Therefore, all or almost all of the cool air can be blown into the storage case 22, so that (articles) in the storage case 22 can be efficiently cooled. In FIG. 14, the cold air guiding member 84 has a reinforcing column member inside. However, the column member may be omitted if it has sufficient strength. Further, the water guide portion having unevenness shown in the third embodiment may be provided on the upper part of the cool air guide member 84.

  The other features are the same as those of the first to third embodiments.

(Modification)
FIG. 15 is a schematic layout diagram showing a closed state of still another example of the drawer-type storage room of the refrigerator according to the present invention. FIG. 16 is a schematic layout diagram showing a state where a drawer type storage room of the refrigerator shown in FIG. 15 is opened. A cool air guide member 85 is provided in the lower freezing compartment 2C2 shown in FIG. The other portions are the same as those of the lower freezing compartment 2, and substantially the same portions are denoted by the same reference numerals, and detailed description of the same portions will be omitted.

  As shown in FIG. 15, in the lower freezing compartment 2C2, the cool air guide member 85 includes an upper surface portion 851 and side surface portions 852 and 853. The rear part of the cool air guide member 85 is inclined upward with respect to the front part.

  Then, as shown in FIG. 16, the flange portion 86 is provided to protrude from below the discharge hole 601 of the partition wall 107. The upper surface portion 851 is parallel to the flange portion 86, and side surface portions 852 and 853 are connected to left and right ends of the upper surface portion 851. The front ends of the side portions 852 and 853 are connected to the storage case 22.

  Then, as shown in FIG. 15, when the door 21 is closed, the front end of the flange 86 faces the front and rear of the storage case 22 via a gap. Then, the lower ends of the side surfaces 852 and 853 approach the flange 86. That is, when the door 21 is closed, the cool air guide member 85 and the collar portion 86 become cylindrical, and the cool air flows through the inside of the cylindrical shape, thereby guiding the cool air to the storage case 22.

  According to such a cool air guiding member 85, the lower surface is open in the shape in which the upper surface portion 851 and the side surface portions 852 and 853 are combined. When resin is molded for the cold air guiding member 85 having such a configuration, the structure of the mold is simplified, and the labor and time required for manufacturing can be reduced.

  Further, the dew water flowing downward along the partition wall 107 flows through the flange 86. Since the front end of the flange 86 faces the rear end of the storage case 22 via the gap, the water does not flow into the storage case 22 but flows down from the gap. At this time, if cool air is flowing over the upper surface of the collar portion 86, sublimation is promoted by the cool air or an effect of pushing into a gap is provided, so that accumulation of water droplets can be suppressed.

  In each embodiment according to the present invention, the lower freezing compartment has been described as an example. However, in addition to this, for example, the upper freezing compartment 3 and the ice making compartment 4 may have the same configuration. The present invention is not limited to these, and can be widely applied to a drawer-type storage room having a structure in which a discharge hole for discharging cool air is provided in a rear wall.

  The embodiments of the present invention have been described above, but the present invention is not limited to the contents. Various modifications can be made to the embodiments of the present invention without departing from the spirit of the invention.

  The refrigerator according to the present invention described above includes a storage member that is slidably received in the storage room in the front-rear direction and that can store articles, a cold air duct that is disposed across a rear wall of the storage room, A discharge hole provided on a rear wall and communicating with the cool air duct, and a cool air guide member provided at a rear end of the storage member and extending rearward is provided, and the storage member is stored in the storage chamber. Then, the rear end of the cool air guiding member is close to the periphery of the discharge hole in the rear wall.

  According to this configuration, since the cool air guiding member is provided at the rear end of the storage member, all or substantially all of the cool air discharged from the discharge holes can be guided to the storage member. Thereby, it is possible to effectively cool the articles stored in the storage member. Further, since the rear end of the cool air guide member is close to the periphery of the discharge hole of the rear wall, the dew condensation water generated on the rear wall is prevented from flowing into the storage member. Thereby, it is possible to suppress the wetness of the stored articles and to prevent the dew condensation water from adhering, so that the sanitary condition inside the storage member can be kept good.

  The above-described refrigerator may be provided with a rib protruding forward from an edge of the discharge hole. With such a configuration, the edge of the ejection hole can be rounded. Thus, it is possible to prevent the finger of the user or the worker, the stored articles, and the like from being damaged. In addition, it is possible to suppress a decrease in freshness and a decrease in quality due to damage to stored articles.

  In the above-described refrigerator, when the storage member moves rearward, the cold air guide member may have a rear end close to a position below the discharge hole in the rear wall. With this configuration, when the flow velocity of the cool air flowing out of the discharge hole is low, the cool air flowing out of the discharge hole immediately flows downward. Since the cool air guide member is provided below, much cool air can be guided to the storage member.

  In the above-described refrigerator, a rear end of the cool air guide member may have flexibility. With this configuration, even if the cold air guide member and the rear wall come into contact with each other due to a change in temperature of the cold air guide member and the rear wall, the cool air guide member is deformed, so that the housing member is not deformed. The slide is not easily disturbed. Thereby, it can suppress that a storage room becomes a sealing failure. Further, even if the cold air guiding member and the rear wall come into contact with each other, the member is hardly damaged. Thereby, even if the proximity distance (gap) to the rear wall of the cool air guiding member is reduced, no trouble is likely to occur. This allows more cool air to flow into the storage member.

  In the above-described refrigerator, the cold air guide member may include a water guide for flowing the water flowing into the upper portion downward. In addition, as a water guide part, the drainage hole which penetrated up and down, the unevenness | corrugation inclined with respect to the direction orthogonal to the moving direction of a storage member, etc. can be mentioned. Thereby, the inflow of dew condensation water into the storage member is suppressed.

  In the above-described refrigerator, the cold air guiding member may have a cylindrical shape. With this configuration, even when the cool air blown out from the discharge holes is directed horizontally or upward and the flow velocity is high, the cool air can be reliably guided to the storage member.

  The above-described refrigerator has a collar portion extending from below the discharge hole, and the cold air guide member, when the storage member is stored in the storage room, an upper surface portion facing the collar portion, A side wall extending from the end of the upper surface in a direction orthogonal to the front-rear direction toward the flange may be provided. With this configuration, when the storage member is stored in the storage room, the cool air guiding member has a cylindrical shape, so that the cool air can be reliably flowed into the storage member. Further, since the cold air guiding member has a shape without a bottom surface, the shape of a mold for molding is simple, and the manufacturing cost can be reduced.

  In the refrigerator described above, the storage member may include a frame and a storage case supported by the frame, and the cool air guide member may be provided in the storage case.

  In the refrigerator described above, the storage member may include a frame and a storage case supported by the frame, and the cold air guide member may be provided on the frame. With this configuration, the shape of the storage case can be made simple. Thereby, at the time of maintenance such as cleaning, repair, and inspection, the storage case can be easily removed, and workability can be improved.
