Description

  The present invention relates to a refrigerator.

  A conventional refrigerator is disclosed in Patent Document 1. The refrigerator includes a storage chamber and a cooling chamber provided behind the storage chamber with a wall surface therebetween. The refrigerator includes an opening on the front surface, a door that closes the opening so as to be opened and closed, and a storage case that is disposed inside the storage chamber and slides forward and backward. The cooling chamber includes a cooler and a fan. And the said wall surface is provided with the blower outlet which blows off the cool air cooled with the said cooler and sent with the said fan in the said storage chamber.

  And the said blower outlet protrudes in the storage chamber. When the storage case is stored in the storage chamber, the tip of the air outlet is inserted into the storage case. With such a configuration, the cold air blown out from the blowout port can be surely flowed into the storage case.

JP-A-7-55321

  In the refrigerator as described above, air that is hotter than the air inside the storage chamber flows from the outside when the article is taken out, stored, and organized with the storage case pulled out from the opening. . In the storage chamber, the wall surface is adjacent to the cooling chamber, so that the temperature is low. When high-temperature air touches the wall surface, water vapor is condensed and water droplets adhere to the wall surface.

  The condensed water flows downward. In the refrigerator of patent document 1, since the said blower outlet protrudes from the said wall surface, dew condensation water accumulates on the upper part of the said blower outlet. And when the said storage case is stored in the said storage chamber, since the front-end | tip of the said blower outlet is inserted in the inside of the said storage case, there exists a possibility that the said dew condensation water may flow in the inside of the said storage case. When condensed water flows into the storage case, the condensed water is applied to the article stored in the storage case and wets the article. Some of the articles need to be stored dry, and the articles may be soiled or damaged. In addition, since the condensed water may contain foreign matters such as dust or germs contained in the external air, if the condensed water is accumulated in the storage container, there may be a problem in terms of hygiene.

  Then, an object of this invention is to provide the refrigerator which can cool the said storage chamber efficiently while suppressing the approach to the storage chamber in which the article | item of condensed water is stored.

  In order to achieve the above object, the present invention includes a storage member that is slidably stored in the storage chamber in the front-rear direction and can store articles, and a cold air duct that is disposed across a wall on the rear side of the storage chamber, A discharge hole provided in the rear wall and communicated with the cold air duct; and a cold air guiding member provided at a rear end of the storage member and extending rearward. The storage member is accommodated in the storage chamber. When this is done, a refrigerator is provided in which the rear end of the cold air guiding member is close to the periphery of the discharge hole of the rear wall.

  According to this configuration, since the cold air guiding member is provided at the rear end of the storage member, all or substantially all of the cold air discharged from the discharge holes can be guided to the storage member. Thereby, it is possible to effectively cool the article stored in the storage member. In addition, since the rear end of the cool air guiding 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, the wetness of the stored article is suppressed, and the condensed water does not adhere, so that the hygienic condition inside the storage member can be kept good.

  The said structure WHEREIN: The refrigerator may be provided with the rib which protrudes ahead from the edge of the said discharge hole. By setting it as such a structure, the edge of a discharge hole can be rounded off. Thereby, it can suppress that a user's or operator's finger | toe, the accommodated goods, etc. are damaged. Moreover, it can suppress that freshness falls or quality falls by the damage of the accommodated articles | goods.

  In the above configuration, in the refrigerator, the cold air guiding member may have a rear end adjacent to the lower side of the discharge hole of the rear wall when the storage member moves rearward. With this configuration, when the flow rate of the cold air flowing out from the discharge hole is slow, the cold air flowing out from the discharge hole immediately flows downward. By providing the cool air guiding member below, a lot of cool air can be guided to the storage member.

  In the above configuration, the refrigerator may have flexibility at a rear end of the cold air guiding member. By configuring in this way, even if the cold air guiding member and the rear wall come into contact with each other due to the deformation due to the temperature change of the cold air guiding member or the rear wall, the cold air guiding member is deformed, thereby The slide is not easily disturbed. Thereby, it can suppress that a store room becomes poor sealing. Further, even if the cold air guiding member and the rear wall are in contact with each other, it is difficult to break. Thereby, even if the proximity distance (gap) with respect to the rear wall of the cold air guiding member is reduced, it is difficult to cause trouble. For this reason, more cold air can flow into the storage member.

  In the above configuration, in the refrigerator, the cold air guiding member may include a water guide portion that causes water that has flowed into the upper portion to flow downward. In addition, as a water guide part, the uneven | corrugated etc. which inclined with respect to the direction orthogonal to the water drain hole penetrated up and down and the movement direction of a storage member can be mentioned. Thereby, the inflow of the dew condensation water into the storage member is suppressed.

  The said structure WHEREIN: A cylinder shape may be sufficient as the said cold air induction | guidance | derivation member. With this configuration, even when the cool air blown out from the discharge hole is oriented horizontally or upward and the flow rate is high, the cool air can be reliably guided to the storage member.

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

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

  In the above-described configuration, the refrigerator may include the storage member having a frame and a storage case supported by the frame, and the cool air induction member may be provided in the frame. By being configured in this way, 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.

In addition, the temperature of each store room is not limited to this, It sets to the temperature which can suppress deterioration of the articles | goods stored in each store room. Further, the user may be able to set the temperature as required or according to his / her preference.

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

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

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

  Discharge holes 601, 602, and 603, which are openings for discharging cool air, are formed in the partition wall 107. In addition, the partition wall 107 is formed with a return port 604 that is an opening through which cool air returns. The cold air blown out from the discharge holes 601, 602, and 603 cools the lower freezer compartment 2, the upper freezer compartment 3, and the ice making chamber 4, respectively, and returns to the cold 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 into the front and the rear.

  The front part of the cool air passage 6 partitioned by the partition member 600 is a cool air duct 605 that guides cool air to the discharge holes 601, 602, and 603. The partition member 600 is in contact with the partition wall 107 at the lower part. Further, the rear portion partitioned by the partition member 600 is a cold air generation flow path 606.

The partition wall 101 is provided with a communication passage 702 that allows the refrigerator compartment 1 and the vegetable compartment 5 to communicate with each other. The cold air is heated to take heat away from the stored items when flowing through the refrigerator compartment 1. Then, the heated cold air flows into the vegetable compartment 5 from the communication path 702. Therefore, the vegetable compartment 5 is maintained at a higher temperature than the refrigerator compartment 1. The cold air flowing through the vegetable compartment 5 returns to the cold air flow path 6 via a return port (not shown). The return ports are provided on the lower side and the back side of the vegetable compartment 5.

Cool the chamber 4. Further, the cold air in the cold air flow path 7 is discharged from the discharge hole 701 provided in the partition wall 108 to cool the refrigerator compartment 1.

(First 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 perform opening and closing. The ice making chamber 4 stores ice produced by the refrigerator Rf, but the basic configuration is the same as that of the lower freezer chamber 2 and the upper freezer chamber 3.

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

  As described above, the drawer-type storage chamber shown in FIG. In the lower freezer compartment 2, a storage case 22 is stored in a storage space 20 having a rectangular parallelepiped shape that is a storage room so as to be movable forward and backward. 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-like 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 surface 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 connecting member 231 is a beam-like member extending in the left-right direction. A guide roller 232 is provided at the rear of the lower surface of the side support rail 230.

  A pair of guide rails 24 extending in the front-rear direction are 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 in 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 relative to the side support rail 230. Further, the guide roller 232 rolls on the upper surface of the guide rail 24. The frame 23 moves back and forth with a small force by the guide roller 232 and the guide roller 241. Further, the lower freezer compartment 2 has a closing mechanism that generates a force to move later by utilizing its own weight when the door 21 and the storage case 22 move to the rear part. The door 21 is reliably closed by this closing mechanism. Moreover, the structure of the lower freezer compartment 2 is not limited to this structure, The structure which supports the door 21 and the storage case 22 so that movement to the front and back is possible is employ | adopted widely.

  As described above, when the storage case 22 is stored in the storage space 20, if the rear end of the storage case 22 comes into contact with the partition wall 107, the lower freezer compartment 2 may be insufficiently sealed. Further, 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 and the partition wall 107 are in contact with each other. In this case, the storage case 22 may be damaged or the partition wall 107 may be damaged. Therefore, when the storage case 22 is stored in the storage space 20, the storage case 22 and the partition wall 107 are not brought into contact with each other. That is, when the storage case 22 is stored, a gap is formed between the rear end of the storage case 22 and the partition wall 107.

  As described above, the partition wall 107 is provided with the discharge hole 601, and the article inside the storage case 22 is cooled by the cold air discharged from the discharge hole 601. For this reason, it is preferable that as much cold air discharged from the discharge holes 601 as possible flows into the storage case 22. Therefore, a cold air guiding member 81 is provided at the rear end of the storage case 22.

  As shown in FIGS. 3 and 4, the cold air guiding member 81 is a plate-like member that extends rearward from the rear end of the upper surface of the storage case 22. The cold air guiding member 81 is inclined rearward, and the rear is higher than the front. The rear end of the cool air guiding 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 wall 107.

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

  The cold air flowing through the cold air duct 605 is the cold 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 wall 107. Therefore, the cold air discharged from the discharge hole 601 has a speed in a direction away from the partition wall 107, and even if there is a gap between the cold air guiding member 81 and the partition wall 107 immediately below the discharge hole 601, Little or no cool air leaks downward from the gap. That is, even if there is a gap between the partition wall 107 around the discharge hole 601 and the cold air guiding member 81 in the configuration in which forced ventilation is performed using the freezer compartment fan 61, the cooling efficiency does not decrease or even decreases. It is minute.

  Further, in the lower freezer compartment 2, the door 21 is opened and closed when an article is 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 freezer compartment 2, moisture contained in the external high-temperature air is condensed. The condensed water flows downward along the partition wall 107. In the lower freezer compartment 2 of the present embodiment, the condensed water droplets flow below the partition wall 107 through a gap between the rear end of the cold air guiding member 81 and the partition wall 107. That is, the dew condensation water that has flowed downward does not flow into the cold air guiding member 81 but flows through the partition wall 107 as it is. Therefore, it is possible to prevent the condensed water from flowing into the storage case 22.

  The lower freezer compartment 2 may store and store articles that cannot be wet, such as medicines and foods. Condensed water may contain dust or other microorganisms, and even when stored items that allow water to wet are stored, the adhesion of condensed water is hygienic. It may not be preferable. By providing the cool air guiding member 81, the stored article can be cooled, and the above-described problems can be suppressed by suppressing the attachment of condensed water to the stored article.

  Moreover, even if there is no problem with the condensed water, some users may feel uncomfortable with the condensed water adhering to the storage case 22. Since the cool air guiding member 81 is provided, the inflow of condensed water into the storage case 22 is suppressed, so that the user can be prevented from feeling uncomfortable.

  The gap between the cold air guiding member 81 and the partition wall 107 is preferably a distance through which condensed water can pass. Further, a container for storing condensed water may be provided below the cold air guiding member 81. In the present embodiment, the cold air guiding 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 cold air guiding member 81 may be combined as separate members.

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

  The cold air induction member 81 described above 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 guiding member 81 are formed of the same material, there may be a difference in deformation due to heat depending on the amount of cold air circulating and the temperature at that time. Therefore, when the gap between the cold air guiding member 81 and the partition wall 107 is designed as a gap through which water can pass, if there is a difference in deformation between the cold air guiding member 81 and the partition wall 107, the cold air guiding member 81 and the partition wall 107 come into contact with each other. However, the door 21 is not securely tightened and the sealing is not defective, or the cold air guiding member 81 or the partition wall 107 is damaged.

  In order to eliminate such problems caused by the contact between the cold air guiding member 81 and the partition wall 107, in the lower freezer compartment 2 shown in FIGS. 5 and 6, the cold air guiding member 81 is made small and flexible at the rear end. A flexible elastic member 811 is attached. By attaching the elastic member 811, the elastic member 811 comes into contact with the partition wall 107 and deforms even if the distance between the cool air induction member 81 and the partition wall 107 becomes smaller than the design value due to a difference in thermal deformation. Therefore, the breakage of the cold air guiding member 81 and the partition wall 107 and the poor sealing of the door 21 can be suppressed.

  In addition, even if the elastic member 811 and the partition wall 107 come into contact with each other, problems do not easily occur. Therefore, the gap between the elastic member 811, that is, the cold air guiding member 81 and the partition wall 107 can be reduced. Thereby, since the cool air flowing downward from the gap between the cool air guiding member 81 and the partition wall 107 can be reduced, more cool air can be guided to the storage case 22. The rear end of the cold air guiding member 81 may have flexibility, or the entire cold air guiding member 81 may have flexibility.

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

  In the lower freezer compartment 2 described above, a cold air guiding member 81 is provided at the rear end of the storage case 2. However, the present invention is not limited to this. The cool air guiding 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, a cold air guiding member 81 is provided on the connecting member 231. That is, the cold air guiding 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.

  By adopting such a configuration, since the cold air guiding member 81 is not attached to the storage case 21, the storage case 21 can be easily attached and detached when performing maintenance such as cleaning and repair.

(Second Embodiment)
The drawer type storage chamber according to the present invention will be described with reference to the drawings. Similar to the first embodiment, the features will be described with the lower freezer compartment 2 as a representative. 9 is a cross-sectional view of another example of the drawer-type storage chamber of the refrigerator according to the present invention, and FIG. 10 is a schematic layout diagram showing a closed state of the storage chamber shown in FIG. In the lower freezer compartment 2A of the present embodiment, a rib 82 protruding forward is provided around the blowout hole 601. Other features are the same as those of the lower freezer compartment 2 of the first embodiment, and substantially the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted.

  As shown in FIGS. 9 and 10, a rib 82 extending forward from the edge of the discharge hole 601 of the partition wall 107 is provided. The rib 82 has a cylindrical 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 cold air guiding member 81, that is, on the back side of the storage space 20.

  By providing the rib 82, it is possible for a user or an operator to suppress sharpening of the edge of the discharge hole 601. Thereby, even if a user's or operator's hand touches the edge of discharge hole 601, or a stored article touches, it can control that a crack is made.

  A rib 82 is provided at the edge of the discharge hole 601, and water accumulates in the rib 82. 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 condensation water that has flowed downward through the partition wall 107 from flowing into the discharge hole 601. Further, since the condensed water is caused to flow in the left and right directions by the ribs 82, the condensed water is also prevented from flowing to the cold air guiding member 81. In addition, as protrusion height of the rib 82, although 2 mm-about 3 mm can be mentioned, for example, it is not limited to this.

  Other features are the same as those in the first embodiment.

(Third embodiment)
The drawer type storage chamber according to the present invention will be described with reference to the drawings. Similar to the first embodiment, the features will be described with the lower freezer compartment 2 as a representative. FIG. 11 is a sectional view of still another example of the drawer-type storage chamber of the refrigerator according to the present invention. The lower freezer compartment 2 </ b> B of the present embodiment is characterized in that a cold air guiding member 83 is provided at the rear end of the storage case 22. Other features are the same as those of the lower freezer compartment 2 of the first embodiment, and substantially the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted.

  The cold air induction member 83 provided in the lower freezer compartment 2B shown in FIG. 11 includes a plurality of drain holes 831 penetrating from the upper surface to the lower surface. The drain hole 831 is a water guide part that causes water that has flowed into the upper part of the cold air guiding member 83 to flow downward.

  Like the cold air guiding member 81 provided in the lower freezer compartment 2, the cold air guiding member 83 is provided with a gap through which condensed water can pass between the partition wall 107 and the cold air guiding member 81. However, when the door 21 is in the closed state, the cold air guiding member 83 itself is also cooled. Therefore, when hot air flows in by opening and closing the door 21, condensation may occur on the cold air guiding member 83 itself. In addition, more condensed water than expected may be attached due to changes in external temperature and humidity. In this case, water flowing downward through the partition wall 107 may flow toward the cold air guiding member 83.

  Thus, when the dew condensation water flows through the cold air guiding member 83, it passes through the drain hole 831 and flows below the cold air guiding member 83. Therefore, the inflow of condensed water into the storage case 22 can be suppressed.

  Other features are the same as those in the first and second embodiments. In addition, the connection part of the cold-air induction | guidance | derivation member 83 and the storage case 22 may be provided with the convex part for suppressing that dew condensation water flows in into the inside of the storage case 22. FIG.

(Modification)
FIG. 12 is a schematic layout view of still another example of the drawer-type storage chamber of the refrigerator according to the present invention. On the upper surface of the cold air guiding member 83 of the lower freezer compartment 2B2 shown in FIG. The water on the upper surface of the cold air guiding member 83 is blocked by the unevenness 832 and the inflow into the storage case 22 is restricted. Further, the unevenness 832 is inclined forward, that is, downward on the right side. Therefore, even if a sufficient amount of water flowing on the upper surface of the cold air guiding member 83 flows in or adheres to the upper surface, the water flows along the unevenness 832 and flows downward from the right end of the cold air guiding member 83. As a result, the inflow of water into the storage case 22 can be suppressed. In addition, the unevenness | corrugation 832 is a water conveyance part. Moreover, you may use the drain hole 831 together.

(Fourth embodiment)
The drawer type storage chamber according to the present invention will be described with reference to the drawings. Similar to the first embodiment, the features will be described with the lower freezer compartment 2 as a representative. FIG. 13 is a cross-sectional view of still another example of the drawer-type storage chamber of the refrigerator according to the present invention. 14 is a schematic layout diagram showing a closed state of the storage chamber shown in FIG. In the lower freezer compartment 2 </ b> C of the present embodiment, a cold air guiding member 84 is provided at the rear end of the storage case 22. Other features are the same as those of the lower freezer compartment 2 of the first embodiment, and substantially the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted.

  As shown in FIGS. 13 and 14, the cold air guiding member 84 has a cylindrical shape that penetrates forward and backward. The cold air guiding member 84 is inclined, and the rear part is higher than the front part. The cool air guiding member 84 has an inflow opening 841 through which cool air flows into the rear end, and an outflow opening 842 through which cool air flows 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 in the front-rear direction.

  When the flow rate of the cold air flowing out from the discharge hole 601 is slow, it is possible to allow all or almost all of the cold air to flow into the storage case 22 by the plate-like cold air guiding 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 air flow 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 cold air duct 605, the cold air may be blown upward from the horizontal. When the cool air is blown out 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 lowered.

  Therefore, by providing the cylindrical cold air guiding member 84, the cold air blown horizontally or upward is forcibly rectified toward the storage case 22. Therefore, all or substantially all of the cool air can be blown into the inside of the storage case 22, so that the inside (the article) of the storage case 22 can be efficiently cooled. In FIG. 14, the cold air guiding member 84 has a reinforcing column member inside, but the column member may be omitted if it has sufficient strength. Moreover, you may provide the water guide part which has an unevenness | corrugation shown in 3rd Embodiment in the upper part of the cold air guide member 84. FIG.

  The other features are the same as those in 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 chamber of the refrigerator according to the present invention. 16 is a schematic layout diagram showing a state in which the drawer-type storage chamber of the refrigerator shown in FIG. 15 is opened. A cool air induction member 85 is provided in the lower freezer compartment 2C2 shown in FIG. The other parts are the same as those in the lower freezer compartment 2, and substantially the same parts are denoted by the same reference numerals and detailed description of the same parts is omitted.

  As shown in FIG. 15, in the lower freezer compartment 2 </ b> C <b> 2, the cool air induction member 85 includes an upper surface portion 851 and side surface portions 852 and 853. The cold air guiding member 85 has a rear portion inclined upward with respect to the front portion.

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

  As shown in FIG. 15, when the door 21 is in the closed state, the front end of the collar portion 86 faces the front end of the storage case 22 through the gap. Then, the lower ends of the side surface portions 852 and 853 approach the collar portion 86. That is, when the door 21 is closed, the cold air guiding member 85 and the collar portion 86 are formed in a cylindrical shape, and the cold air flows inside the cylindrical shape, thereby guiding the cold air to the storage case 22.

  According to such a cool air guiding member 85, the lower surface of the shape combining the upper surface portion 851 and the side surface portions 852 and 853 is open. When molding 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 condensation water that has flowed downward along the partition wall 107 flows through the collar portion 86. Since the front end of the collar portion 86 faces the rear end of the storage case 22 through a gap, water does not flow into the storage case 22 but flows down from the gap. At this time, if the cool air is flowing on the upper surface of the collar portion 86, sublimation is promoted by the cool air or it is pushed into the gap, so that accumulation of water droplets can be suppressed.

  In each embodiment according to the present invention, the lower freezer compartment has been described as an example. However, for example, the upper freezer compartment 3 and the ice making chamber 4 may have the same configuration. Further, the present invention is not limited to these, and the present invention can be widely used in a drawer-type storage chamber having a discharge hole for discharging cool air on the rear wall.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this content. The embodiments of the present invention can be variously modified without departing from the spirit of the invention.

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

  According to this configuration, since the cold air guiding member is provided at the rear end of the storage member, all or substantially all of the cold air discharged from the discharge holes can be guided to the storage member. Thereby, it is possible to effectively cool the article stored in the storage member. In addition, since the rear end of the cool air guiding 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, the wetness of the stored article is suppressed, and the condensed water does not adhere, so that the hygienic condition inside the storage member can be kept good.

  The refrigerator mentioned above may be provided with a rib protruding forward from the edge of the discharge hole. By setting it as such a structure, the edge of a discharge hole can be rounded off. Thereby, it can suppress that a user's or operator's finger | toe, the accommodated goods, etc. are damaged. Moreover, it can suppress that freshness falls or quality falls by the damage of the accommodated articles | goods.

  In the refrigerator described above, the cold air guiding member may have a rear end adjacent to the lower side of the discharge hole of the rear wall when the storage member moves rearward. With this configuration, when the flow rate of the cold air flowing out from the discharge hole is slow, the cold air flowing out from the discharge hole immediately flows downward. By providing the cool air guiding member below, a lot of cool air can be guided to the storage member.

  In the refrigerator described above, the rear end of the cold air guiding member may have flexibility. By configuring in this way, even if the cold air guiding member and the rear wall come into contact with each other due to the deformation due to the temperature change of the cold air guiding member or the rear wall, the cold air guiding member is deformed, thereby The slide is not easily disturbed. Thereby, it can suppress that a store room becomes poor sealing. Further, even if the cold air guiding member and the rear wall are in contact with each other, it is difficult to break. Thereby, even if the proximity distance (gap) with respect to the rear wall of the cold air guiding member is reduced, it is difficult to cause trouble. For this reason, more cold air can flow into the storage member.

  In the refrigerator described above, the cold air guiding member may include a water guide portion that causes water flowing into the upper portion to flow downward. In addition, as a water guide part, the uneven | corrugated etc. which inclined with respect to the direction orthogonal to the water drain hole penetrated up and down and the movement direction of a storage member can be mentioned. Thereby, the inflow of the dew condensation water into the storage member is suppressed.

  In the refrigerator described above, the cold air guiding member may be cylindrical. With this configuration, even when the cool air blown out from the discharge hole is oriented horizontally or upward and the flow rate is high, the cool air can be reliably guided to the storage member.

  The refrigerator described above has a flange portion extending from below the discharge hole, and the cold air guiding member has an upper surface portion that faces the flange portion when the storage member is stored in the storage chamber, You may provide the side wall part extended toward the said collar part from the edge part of the direction orthogonal to the said front-back direction of an upper surface part. With this configuration, when the storage member is stored in the storage chamber, the cold air guiding member has a cylindrical shape, so that the cold air can surely flow into the storage member. Further, since the cold air guiding member has a shape without a bottom surface, the shape of the molding die 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 induction 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 cool air induction member may be provided in the frame. By being configured in this way, 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.
