And it cools again by the cooler 5, and cold air is circulated through the refrigerator main body 1. FIG.

  1 is an example of the configuration of the refrigerator main body 1, and a cold air branching portion 91 is formed in a part of the cold air passage 6. On the other hand, what is shown in FIG. 2 is another example of the configuration of the refrigerator main body 1, and by providing a branch cover 92 on the back side in the room 2, the cold air branch portion 91 is provided separately from the cold air passage 6. It is to be formed.

  That is, as shown in FIG. 2, a branch cover 92 is attached between the shelf (shelf plate) 3 and the back surface in the room 2. The cold air passage 6 is provided with an opening penetrating the back surface in the room 2, and the branch cover 92 is provided so as to cover the opening from the room 2.

The branch cover 92 is provided with a plurality of cold air outlets 9. These cold air outlets 9 are arranged on the back side (back side) of each space partitioned by the shelf (shelf plate) 3. The space in the branch cover 92 configured as described above forms a cold air branch portion 91.
Other configurations are the same as those shown in FIG.

  In the refrigerator configured as described above, the air cooled by the cooler 5 passes through the cool air passage 6 and enters the cool air branch portion 91 in the branch cover 92. In the cold air branching portion 91, the air is distributed to the respective cold air outlets 9 and blown out from the respective cold air outlets 9 into the room 2.

  By adopting a configuration in which the branch cover 92 as shown in FIG. 2 is provided, the arrangement of the cold air outlet 9 and / or the shape of the cold air branch portion 91 can be changed simply by replacing the branch cover 92. . Hereinafter, in view of such advantages, a case where a configuration including the branch cover 92 shown in FIG. 2 is employed will be described as an example.

  Next, the details of the configuration of the shelf (shelf plate) 3 provided in the refrigerator according to Embodiment 1 of the present invention will be described with reference to FIGS. 3 and 4. A shelf lower surface wing 31 and a shelf lower surface rib 32 are provided on the lower surface of the shelf (shelf plate) 3. The shelf lower surface wing 31 is attached to the back side of the shelf (shelf plate) 3, that is, a position closer to the back side. In other words, the shelf lower surface wing 31 is arranged at a location near the cold air outlet 9 on the lower surface of the shelf (shelf plate) 3.

  Here, at least one of the plurality of cold air outlets 9 provided in the branch cover 92 is a shelf arranged so that the cold air is blown out (along) toward the lower surface of the shelf (shelf plate) 3. It is provided as an outlet 921 for the lower surface.

  The shelf lower surface wing 31 is formed of a flat plate-like or wing-like member disposed substantially parallel to the lower surface of the shelf (shelf plate) 3. The shelf lower surface wing 31 is attached so as to hang downward from the lower surface of the shelf (shelf plate) 3. Here, the shelf lower surface wing 31 is arranged substantially in parallel with the shelf (shelf plate) 3, and the back side close to the shelf lower surface outlet 921 of the shelf lower surface wing 31 is lower and the door side is higher. In other words, it is more desirable that the distance between the upper surface of the shelf lower surface wing 31 and the lower surface of the shelf (shelf plate) 3 is arranged to be farther away from the back side and closer to the door side. .

  In addition, when the shelf lower surface wing 31 is arranged in parallel with the lower surface of the shelf (shelf plate) 3, the cold air outlet 9 is provided for the distance between the shelf lower surface wing 31 and the lower surface of the shelf (shelf plate) 3. That is, the location near the inner wall surface and the location far from the inner wall surface are equal. Therefore, when expressing both the case where the shelf lower surface wing 31 is arranged in parallel to the lower surface of the shelf (shelf plate) 3 and the case where the shelf lower surface wing 31 is inclined so as to descend toward the back side, the shelf lower surface wing 31 is expressed. The distance from the lower surface of the shelf (shelf) 3 at a location near the inner wall surface where the cold air outlet 9 is provided is equal to or greater than the distance from the lower surface of the shelf (shelf) 3 at a location far from the inner wall surface. It is arranged so that.

  Further, at this time, the rear end of the shelf lower surface wing 31 is disposed below the corresponding shelf lower surface outlet 921 so that it flows out of the shelf lower surface outlet 921. The cold air can be lifted and guided along the lower surface of the shelf (shelf plate) 3 by the shelf lower surface wing 31.

  In addition, by making the cross-sectional shape of the shelf lower surface wing 31 thicker at the back side close to the outlet 921 for the shelf lower surface and thinner at the door side, turbulent flow generation at the end of the shelf lower surface wing 31 is suppressed. can do. In addition, as a cross-sectional shape of the shelf lower surface wing 31, turbulent flow is also generated by rounding the tip of the shelf lower surface outlet 921 side on an arc or by making the entire cross section of the shelf lower surface wing 31 draw an arc. Can be suppressed.

  Further, the tip of the shelf lower surface wing 31 on the shelf lower surface outlet 921 side is disposed so as to be positioned closer to the door than the tip of the shelf (shelf plate) 3 to which the shelf lower surface wing 31 is attached. . That is, the front end of the shelf lower surface wing 31 on the shelf lower surface side of the shelf lower surface wing 31 and the door of the branch cover 92 than the distance between the rear end of the shelf (shelf plate) 3 and the end surface of the branch cover 92 on the door side. The distance between the side end faces is wider.

  By arranging in such a positional relationship, a part or most of the cold air flowing out from the outlet 921 for the lower surface of the shelf is caused by the shelf lower surface wing 31 and the shelf (shelf plate) 3 above the shelf lower surface wing 31. The remaining air is led to the space above the shelf (shelf plate) 3 on the lower side of the shelf lower surface wing 31.

  In a situation where the amount of food placed on the shelf (shelf plate) 3 below the shelf lower surface wing 31 is not large and the cold air flows smoothly, the cool air is blown regardless of the upper and lower sides of the shelf lower surface wing 31, and the shelf lower surface When the amount of food placed on the shelf (shelf) 3 below the wing 31 is large, the airflow along the lower surface of the shelf (shelf) 3 on the upper side of the shelf lower surface wing 31 preferentially prevails. Can be formed.

  In addition, as shown in FIG. 4, the lateral width of the shelf lower surface wing 31 is wider than the lateral width of the outlet 921 for the shelf lower surface. By doing in this way, before the cool air which flowed out in the room 2 from the blower opening 921 for the shelf lower surface diffuses in the right and left (lateral direction), the shelf lower surface wing 31 receives the cool air, thereby the shelf (shelf plate) 3. More airflow directed toward the lower surface of the can be obtained.

  Furthermore, as shown in FIG. 4, the shelf lower surface wing 31 is arranged inside the shelf (shelf plate) 3 in plan view. That is, the shelf lower surface wing 31 is formed so that the projected area of the shelf lower surface wing 31 on the projection plane parallel to the upper surface of the shelf (shelf plate) 3 is smaller than the area of the upper surface of the shelf (shelf plate) 3. Has been. For this reason, since the shelf lower surface wing 31 is hidden under the shelf (shelf plate) 3, even if food waste, liquid, or the like falls from the shelf (shelf plate) 3, the shelf lower surface wing These can be prevented from sagging on the upper surface of 31 and being contaminated, so that sanitary properties can be prevented from deteriorating.

  As described above, the shelf lower surface rib 31 is also provided on the lower surface of the shelf (shelf plate) 3 provided with the shelf lower surface wing 31 in addition to the shelf lower surface wing 31. The shelf lower surface rib 32 is provided so as to protrude from the lower surface of the shelf (shelf plate) 3 substantially vertically downward. The shelf lower surface rib 32 prevents the airflow that is guided by the shelf lower surface wing 31 from the back side to the near side of the bottom surface of the shelf (shelf plate) 3 from being naturally dissipated from side to side. ) Regulate the direction of the cold air flow along the lower surface of 3.

  In the example shown in FIG. 4, four shelf lower surface ribs 32 are provided. Each of the shelf lower surface ribs 32 has a shape that bends so as to spread to the left and right outer sides as it goes to the door side. By doing in this way, the airflow guided along the lower surface of the shelf (shelf plate) 3 by the shelf lower surface wing 31 is guided toward the left and right outer sides on the lower surface of the shelf (shelf plate) 3. For this reason, even when the width of the outlet 921 for the lower surface of the shelf is narrow, the cold air can be spread over a wide range on the lower surface of the shelf (shelf plate) 3.

  In the example shown in FIG. 4, a rib that guides cold air from the back side near the shelf lower surface wing 31 to the vicinity of the center of the shelf (shelf plate) 3, and the position on the door side of the shelf lower surface wing 31 (shelf (shelf plate) 2) Ribs for guiding cold air from the vicinity of the center of 3) to the vicinity of the door side end of the shelf (shelf plate) 3 are formed in pairs. As described above, by arranging the start position and the end position of the shelf lower surface rib 32 at appropriate positions, the cool air can be efficiently guided. Then, for example, as shown in FIG. 4, it can be widespread over the entire area, or conversely, it can flow intensively in a part.

  One or more refrigerators configured as described above are provided in a room provided in the refrigerator main body, a shelf plate for placing the contents on the upper surface thereof, a cooler that cools the air and generates cold air, and A cool air passage for supplying cool air generated by the cooler to the room, a blower for generating an air flow for sending cool air to the room in the cool air passage, and a cool air passage, provided on the inner wall surface of the room The distance between the cold air outlet and the lower surface of the shelf at a location close to the inner wall provided with the cold air outlet is below the at least one shelf. A shelf lower surface wing 31, which is a wing disposed so as to be at least a distance from the lower surface of the shelf board.

  For this reason, the flow of the cold air from the cold air outlet can be guided along the shelf (shelf plate) 3 by the shelf lower surface wing 31. Then, by creating a flow of cool air along the lower surface of the shelf (shelf) 3, the shelf (shelf) 3 is cooled from the lower surface, and heat conduction through the shelf (shelf) 3 causes the shelf (shelf) 3 It is possible to efficiently cool the contents placed on the upper surface of the.

  Further, by forming the cold air flow so as to be collected in the vicinity of the lower surface of the shelf (shelf plate) 3, the flow of the cold air is obstructed by the stored items even when the amount of the stored items in the warehouse increases. It is possible to suppress the occurrence of uneven temperature distribution in the cabinet.

  Therefore, when a large amount of food is stored in the refrigerator, in the conventional refrigerator, the gap between the food and / or the container is scarce, and the cooling of the food newly placed for cooling is slowed by blocking the cold air. Ingredients may deteriorate. On the other hand, according to the refrigerator according to the present invention, the refrigerator is placed so as to be in contact with the shelf (shelf) 3 having the shelf lower surface wing 31 attached to the lower surface thereof, or already placed on the shelf (shelf) 3. It can be cooled efficiently by placing it on the cooled foodstuff.

  Further, the shelf lower surface wing 31 is provided with shelf lower surface ribs 32 provided on the lower surface of the shelf (shelf plate) 3 to which the shelf lower surface wing 31 is attached. The cold air guided to flow along the lower surface of the plate (3) can be distributed to a desired location on the lower surface of the shelf (shelf plate) 3 by the shelf lower surface rib 32, thereby realizing efficient cooling. Contribute.

  Further, two or more shelf lower surface ribs 32 are provided, and the space between the two shelf lower surface ribs 32 of the two or more shelf lower surface ribs 32 is provided on the inner wall surface provided with the cold air outlet 9. Even if the width of the outlet 921 for the lower surface of the shelf is narrow as described above, the shelf (shelf (shelf)) is arranged so that the interval at the close location is narrower than the interval at the location far from the inner wall surface. Cold air can be spread over a wide area on the lower surface of the plate 3.

  In addition, as material which comprises the shelf (shelf board) 3, when importance is attached to the thermal conductivity of the shelf (shelf board) 3, aluminum, carbon, etc. are used for at least a part of the shelf (shelf board) 3. It is desirable to do. In addition, when importance is placed on the visibility in the room of the refrigerator, it is desirable to use transparent resin, glass, or the like for at least a part of the shelf (shelf plate) 3.

FIG. 5 is a perspective view schematically showing an example of a shelf provided in the refrigerator and an enlarged view of the main part thereof, and FIG. 6 is a shelf provided in the refrigerator. It is the perspective view which shows other examples typically, and the enlarged view of the principal part.
The second embodiment described here is a configuration in which the shelf lower surface wing 31 and / or the shelf lower surface rib 32 are detachably attached to the shelf (shelf plate) 3 in the configuration of the first embodiment described above.

  First, an example of the configuration of the second embodiment of the present invention will be described with reference to FIG. In the example shown in FIG. 5, engaging portions are formed at both left and right ends of the shelf lower surface wing 31. This engaging part is comprised from the site | part which stood up upwards from each of the right-and-left both ends of the shelf lower surface wing 31, and the site | part provided substantially horizontally over the left-right direction in the upper end of the said upright site | part. The engaging portion thus formed has a substantially T-shape when viewed from the front.

  A shelf lower surface sleeve 301 is provided on the lower surface of the shelf (shelf plate) 3. Two shelf lower sleeves 301 are provided in pairs corresponding to the left and right engaging portions of the shelf lower wing 31. One shelf lower surface sleeve 301 corresponds to the shape of the engaging portion of the shelf lower surface wing 31 (substantially T-shaped), and a substantially L-shaped part in front view and a substantially inverted L-shaped part in front view are paired. Configured.

  The shelf lower surface wing 31 can be attached to and detached from the lower surface of the shelf (shelf plate) 3 by sliding the engaging portion of the shelf lower surface wing 31 configured in this way to the shelf lower surface sleeve 301 from the front and rear direction. Can be attached.

  Next, another example of the configuration of the second embodiment of the present invention will be described with reference to FIG. In the example shown in FIG. 6, wing suspension members 311 are respectively attached to the four corners of the shelf lower surface wing 31. These wing suspension members 311 are erected upward from the four corners of the shelf lower surface wing 31.

  A shelf lower surface mounting portion 302 is provided on the lower surface of the shelf (shelf plate) 3. The shelf lower surface attachment portion 302 is disposed corresponding to each of the wing suspension members 311 of the shelf lower surface wing 31. The wing suspension member 311 has a hollow cylindrical shape in which a hole is provided along the central axis. On the other hand, each shelf lower surface mounting portion 302 is provided with a protruding portion that protrudes downward to engage with the hole of the wing suspension member 311. Then, the shelf lower surface wing 31 can be detachably attached to the shelf (shelf plate) 3 by engaging the protrusion of the shelf lower surface attachment portion 302 with the hole of the wing suspension member 311.

  In addition, as shown in FIG. 6, you may arrange | position the some shelf lower surface attaching part 302 in a grid | lattice form etc. according to the space | interval dimension between the wing suspension members 311 of the shelf lower surface wing 31. FIG. By doing in this way, the attachment position of the shelf lower surface wing 31 can be changed by selecting suitably the shelf lower surface attachment part 302 engaged with the wing suspension member 311. The same applies to the shelf lower surface sleeve 301 in the example shown in FIG.

  Note that the shelf lower surface rib 32 may also be detachably attached to the shelf (shelf plate) 3 in the same manner as the shelf lower surface wing 31. In this way, the shelf lower surface wing 31 and / or the shelf lower surface rib 32 can be removed and washed to maintain hygiene, to be replaced when broken, to be removed in the case of obstruction, specifications such as length and size It is possible to change the cold air transfer function by changing to a different one.

  Further, the shelf lower surface wing 31, the shelf lower surface rib 32, the shelf lower surface sleeve 301, the shelf lower surface mounting portion 302, and the wing suspension member 311 are made of a flexible, flexible or elastic material such as silicone rubber or a soft resin material. Etc. are desirable. Since the shelf lower surface wing 31 and the shelf lower surface rib 32 protrude into the food storage space, there is a high possibility that the shelf lower surface wing 31 and the food storage container come into contact with the food material or food container. Therefore, by using the material having the above-described properties, it is possible to prevent the shelf lower surface wing 31 and the like from being damaged and the food and the container from being damaged.

It can be made difficult to come off.

  In addition, the shelf (shelf plate) 3 may be transparent (for example, colorless and transparent), and the shelf lower surface wing 31 and / or the shelf lower surface rib 32 may be colored. By doing in this way, the user can easily visually recognize the position where the shelf lower surface wing 31 and / or the shelf lower surface rib 32 is arranged from the upper side of the shelf (shelf plate) 3.

  Then, the user can easily check the position of the shelf lower surface wing 31 and / or the shelf lower surface rib 32 by visually confirming the position of the shelf lower surface wing 31 and / or the shelf lower surface rib 32 to form the path of the cold air formed. It becomes possible to guess. Therefore, the user can easily hit a desired position in the warehouse with cold air and form a spot that can maintain a lower temperature, or easily determine the position where the food is placed by visual observation.

Specifically, for example, a shelf lower surface wing 31 and a shelf lower surface rib 32 that are colored in blue so that the cool air is most guided to the left front on the lower surface of the shelf (shelf plate) 3 are installed, and the cool air is shielded from the right front. The shelf lower surface rib 32 colored in red is installed. In the vicinity of the blue shelf lower rib 32, food that is desired to be cooled quickly, or food that tastes better or is likely to deteriorate if the temperature is kept low is placed. On the other hand, in the vicinity of the red shelf lower rib 32, food that may be slowly cooled or food that does not need to be kept at a low temperature is placed. Such a device can be taken and the refrigerator can be customized to be more efficient and convenient for the user.
Other configurations are the same as those in the first embodiment, and detailed description thereof is omitted.

Embodiment 3 FIG.
7 to 11 relate to Embodiment 3 of the present invention. FIG. 7 is a sectional view schematically showing an example of a shelf provided in the refrigerator as viewed from the side, and FIG. 8 is shown in FIG. FIG. 9 is a perspective view schematically showing the shelf shown in FIG. 7, and FIG. 10 is a perspective view of another example of the shelf provided in the refrigerator from above. FIG. 11 is a perspective view schematically showing the shelf shown in FIG. 10.

  The third embodiment described here descends to a position almost at the end where cold air is guided by the shelf lower surface rib 32 provided on the lower surface of the shelf (shelf plate) 3 in the configuration of the first embodiment or the second embodiment. The flow rib 33 is provided.

  That is, as shown in FIGS. 7 to 9, the downflow rib 33 is provided at a position near the door on the lower surface of the shelf (shelf plate) 3 and where the cool air is guided by the shelf lower surface rib 32. ing. The downflow rib 33 is provided so as to protrude obliquely downward from the lower surface of the shelf (shelf plate) 3 to the door side. In other words, the length of the downflow rib 33 is arranged so as to cross the path of the airflow formed along the lower surface of the shelf (shelf plate) 3.

  The flow direction of the cool air flowing toward the door side along the lower surface of the shelf (shelf plate) 3 by the action of the shelf lower surface wing 31 and the shelf lower surface rib 32 is changed downward by the downward flow rib 33. For example, as shown in FIG. 9, cold air is directed to the quenching spot 10 set on the shelf (shelf plate) 3 below the shelf (shelf plate) 3 provided with the downflow ribs 33.

  In addition, as shown in FIG. 8, when the cold air outlet 9 is provided at a position near the side wall surface in the room 2 in the branch cover 92 to generate a flow of cold air along the side wall surface in the room 2, Side ribs 34 may be provided on the side walls. The side rib 34 is provided at a position near the door of the side wall in the room 2. The side ribs 34 are provided so as to protrude obliquely inward from the side wall surface in the room 2 to the door side. In other words, the length of the side rib 34 is arranged so as to cross the path of the airflow formed along the side wall surface.

  The flow direction of the cold air flowing toward the door side along the side surface in the room 2 is changed to the inner direction by the side rib 34. Then, for example, as shown in FIG. 9, cold air is directed to the quenching spot 10.

  In this manner, in the quenching spot 10 formed by providing the downflow rib 33 and / or the side rib 34 in addition to the configuration of the first or second embodiment, the wind speed is higher than that of other portions. Is early. For this reason, when hot food is placed in the quenching spot 10, it quickly cools, or an air curtain is formed between the food already cooled in the vicinity, and the rising airflow and heat pool generated around the hot food Can be resolved. And while guiding an airflow to the cold return part 7 quickly, it can suppress that a surrounding foodstuff raises a temperature by radiant heat.

  In order to make it easier for the user to visually recognize the position where the quenching spot 10 is formed, the quenching spot 10 on the upper surface of the shelf (shelf plate) 3 below the shelf (shelf plate) 3 provided with the downflow ribs 33 is provided. Marking may be applied to the position where the mark is formed. The marking or quenching spot 10 is disposed at a position where the downflow generated by the downflow rib 33 and / or the airflow guided to the inside of the room 2 by the inner wall rib (side rib 34).

  Moreover, what is shown in FIG.10 and FIG.11 is the example comprised so that the position where the quenching spot 10 was formed can be moved by making the position of the downflow rib 33 movable. In this configuration, first, at least two pairs of shelf lower surface ribs 32 are formed of a material having flexibility, flexibility, or elasticity. Then, the back sides of the pair of shelf lower surface ribs 32 are fixed to, for example, wing suspension members 311. Further, the door-side end portions of the pair of shelf lower surface ribs 32 are connected to the left and right ends of the downflow ribs 33. The downflow rib 33 is attached so as to be movable in the left-right direction along the lower surface of the shelf (shelf plate) 3.

  By doing in this way, it is possible to change the position of the downflow rib 33 in the left-right direction. At this time, the shelf lower surface rib 32 is also deformed in accordance with the changed position of the downflow rib 33, and a path for guiding cool air from the back side to the position where the downflow rib 33 is present is formed. Here, as shown in FIG. 11, the convenience of changing the position of the downflow rib 33 can be improved by providing a handle 331 on the door side of the downflow rib 33.

With the configuration described above, when the handle 331 of the downflow rib 33 is slid to the left and right, the bending direction of the shelf lower surface rib 32 follows accordingly, and the quenching spot 10 is formed below the downflow rib 33. Therefore, when a user tries to add a new hot food or container in the cabinet, the user roughly arranges the food in the lower space of the shelf (shelf) 3 to create a space. By newly placing the food to be cooled and sliding the downflow rib 33 to the vicinity of the upper portion of the food, the cool air is guided to the vicinity of the newly added food and can be efficiently cooled.
Other configurations are the same as those in the first or second embodiment, and detailed description thereof is omitted.

Embodiment 4 FIG.
FIG. 12 relates to Embodiment 4 of the present invention, and is a cross-sectional view schematically showing a state in which a shelf provided in the refrigerator is viewed from the side.
In the fourth embodiment described here, in addition to the configuration of any of the first to third embodiments described above, a shelf lower surface fan 35 is provided on the lower surface of the shelf (shelf plate) 3 as shown in FIG. Is further provided. Here, the shelf lower surface fan 35 is a shelf (shelf plate) 3 and is disposed substantially immediately above the shelf lower surface wing 31.

  The shelf lower surface fan 35 is attached such that the rotation axis is substantially perpendicular to the lower surface of the shelf (shelf plate) 3. When the shelf lower surface fan 35 is rotated, the cold air on the shelf lower surface wing 31 is sucked further upward, and the cold air quickly flows along the lower surface of the shelf (shelf plate) 3. Here, as shown in FIG. 12, the end of the back side of the shelf (shelf plate) 3 to which the shelf lower surface fan 35 is attached is bent downward, so that the cold air sucked up by the shelf lower surface fan 35 is deeply absorbed. It can prevent returning to the side.

  Further, by making the fan rotation speed of the shelf lower surface fan 35 variable, the amount of cold air along the lower surface of the shelf (shelf plate) 3 is appropriately adjusted according to the internal temperature, the amount of food stored and the degree of clogging. Can be adjusted. Furthermore, the presence or absence of the quenching spot 10 can be switched by stopping the shelf lower surface fan 35.

In addition, by supplying power to the shelf lower surface fan 35 by wireless power transfer using an induction coil or the like, the shelf lower surface fan 35 can be installed without hindering the attachment or detachment or arrangement of the shelf (shelf plate) 3. It is easy to use.
Other configurations are the same as those in any one of the first to third embodiments, and detailed description thereof is omitted.

  As described above, by providing the shelf lower surface fan 35 between the lower surface of the shelf (shelf plate) 3 and the shelf lower surface wing 31, the cold air blown out from the cold air outlet 9 (the outlet 921 for the shelf lower surface) can be quickly discharged. The airflow along the lower surface of the shelf (shelf plate) 3 can be guided to the airflow.

Embodiment 5. FIG.
FIG. 13 relates to Embodiment 5 of the present invention, and is a cross-sectional view schematically showing a state in which a shelf provided in the refrigerator is viewed from the side.
In the fifth embodiment described here, in the configuration of any of the first to fourth embodiments described above, the installation position of the shelf (shelf plate) 3 is made movable in the vertical direction, and the shelf The cool air can be constantly blown to the lower surface of the shelf (shelf plate) 3 regardless of the position of the (shelf plate) 3.

  In the fifth embodiment, the shelf (shelf plate) 3 is supported by a support mechanism (not shown) so that its installation position can be moved in the vertical direction within a predetermined range. In this case, the opening size in the vertical direction of the outlet 921 for the lower surface of the shelf is increased so that at least the lower surface of the shelf (shelf plate) 3 is located at any position within the range. If cold air is blown to the wings 31, a temporary purpose is achieved.

  That is, the upper end of the shelf lower surface outlet 921 is located above the shelf lower surface wing 31 when the three shelves (shelf plates) are arranged at the top in the above range, and the shelf lower surface outlet 921. The size of the outlet 921 for the lower surface of the shelf is such that the lower end of the shelf is positioned below the lower surface of the shelf (shelf plate) 3 when the shelf (shelf plate) 3 is disposed at the lowest position within the range. And the position may be adjusted.

  However, in this configuration, since the opening area of the outlet 921 for the lower surface of the shelf is widened, there is a possibility that inconveniences such as insufficient wind speed of the cold air blown from the outlet 921 for the lower surface of the shelf may occur. Moreover, the case where the gap | deviation arises between the shelf lower surface wing 31 and the blower outlet 921 for shelf lower surfaces by restrictions, such as a structure, is also considered.

  Therefore, in such a case, as shown in FIG. 13, by providing the shelf-outlet connection portion 36, the opening area of the outlet 921 for the lower surface of the shelf is kept small, and the shelf (shelf plate) 3 is provided. Cool air can be sent to the shelf lower surface wing 31 of the shelf (shelf plate) 3 regardless of the position in the vertical direction.

  That is, in the configuration shown in FIG. 13, the opening size in the vertical direction of the outlet 921 for the bottom surface of the shelf is the shelf (shelf plate) 3 regardless of the vertical position of the shelf (shelf plate) 3 as described above. It is enlarged to such an extent that cold air can be sent to the shelf lower surface wing 31. And the shelf-air outlet connection part 36 is attached to the air outlet 921 for the shelf lower surface so as to be movable in the vertical direction.

  The shelf-air outlet connection portion 36 includes a plate-like member having a size that can sufficiently cover the air outlet 921 for the lower surface of the shelf. The vertical dimension of the plate-like member is adjusted to be slightly larger than the dimension of the outlet 921 for the lower surface of the shelf plus the dimension of the vertical movable range of the shelf (shelf plate) 3. And the said plate-shaped member of this shelf-air outlet connection part 36 and the shelf (shelf plate) 3 movable up and down are connected via the rod-shaped member. In this way, the shelf (shelf plate) 3 and the shelf-air outlet connection portion 36 are provided so as to be substantially integrated and movable in the vertical direction.

  The plate-like member of the shelf-air outlet connection portion 36 is provided with an opening having an opening area similar to that of the other cold air outlets 9. That is, the opening area of this opening is smaller than the opening area of the outlet 921 for the lower surface of the shelf where the shelf-outlet connection part 36 is provided. The opening is arranged at a position where cool air can be blown out toward the lower surface of the shelf (shelf plate) 3. As described above, since the shelf (shelf) 3 and the shelf-outlet connection portion 36 move substantially integrally, even if the shelf (shelf) 3 is moved up and down, the shelf (shelf) 3 and The relative positional relationship with the shelf-outlet connection portion 36 does not change. Accordingly, the relative position between the opening provided in the shelf-outlet connection portion 36 and the shelf (shelf plate) 3 is also unchanged.

  For this reason, even if the shelf (shelf plate) 3 is moved up and down, the opening provided in the shelf-outlet connection portion 36 can always blow cold air toward the lower surface of the shelf (shelf plate) 3. The possible positional relationship can be maintained. In addition, a portion of the outlet 921 for the lower surface of the shelf where cold air is blown out to other than the lower surface of the shelf (shelf plate) 3 can be covered by the plate-like member of the shelf-outlet connection portion 36. Therefore, it is possible to prevent the cool air from flowing out toward the lower surface of the shelf (shelf plate) 3 and efficiently blow out the cold air to the lower surface of the shelf (shelf plate) 3.

  When the shelf (shelf) 3 is detachably provided in the room 2, the shelf (shelf) 3 and the shelf-outlet connection portion are connected to the shelf (shelf) 3 via the rod-shaped member in accordance with the attachment / detachment of the shelf (shelf) 3. It is preferable that the connection with 36 can be smoothly connected and disconnected.

  In the refrigerator configured as described above, the shelf (shelf) 3 is provided so as to be movable in the vertical direction, and the cold air outlet 9 (the outlet 921 for the lower surface of the shelf) has an upper end at the shelf (shelf) 3. The lower end of the movable range is arranged below the lower end of the movable range of the shelf (shelf plate) 3.

  For this reason, cold air can be sent from the outlet 921 for the lower surface of the shelf to the lower surface wing 31 of the shelf (shelf) 3 at any position within the movable range.

  Further, a shelf having an opening that is provided in the outlet 921 for the lower surface of the shelf so as to be movable in the vertical direction integrally with the shelf (shelf plate) 3 and has an opening area smaller than the outlet 921 for the lower surface of the shelf. By providing the outlet connection portion 36, the cool air can be sent toward the lower surface of the shelf (shelf plate) 3 regardless of the position of the shelf (shelf plate) 3, and the shelf (shelf) The cool air can be prevented from flowing out to the lower surface of the plate 3, and the cool air can be efficiently sent to the lower surface of the shelf 3.
