Description

  The present invention relates to a refrigerator.

  The ethylene gas emitted from the vegetables in the refrigerator tends to promote the aging of other vegetables in the refrigerator. Therefore, attempts have been made to decompose ethylene gas in the warehouse and convert it into carbon dioxide that can suppress ripening of plants. Moreover, the trial which delays ripening of the other vegetables in a warehouse is also performed by raising the sealing degree in a warehouse and filling the inside with the converted carbon dioxide.

  As a technique related to these attempts, a technique described in Patent Document 1 is known. In Patent Document 1, a barrier member having elasticity and antibacterial properties for preventing inflow and outflow of the atmosphere is provided over the entire joint portion of the storage container and the storage container lid, and the temperature in the storage container is changed from 5 ° C. to a temperature near the freezing point. In addition, the humidity in the storage chamber is controlled by warm air containing moisture that evaporates from stored food and moisture that flows in when the lid of the storage container is opened and closed by an antibacterial moisture absorbing and releasing member that has both high moisture absorption and moisture release properties. It is described that it is controlled to 95% RH (relative humidity) or more.

  Patent Document 1 also discloses a configuration in which the atmosphere gas composition is reduced in oxygen concentration by the oxygen partial pressure action of the oxygen permeable membrane utilizing the breathing action of stored food, and ethylene gas emitted from the stored food is decomposed by the catalyst member. Further, it is described that moderate convection is generated in the storage container by further setting the cooling temperature on the upper surface side of the storage container lower than that on the lower surface side.

JP-A-8-136113

  When the degree of sealing in the chamber increases, carbon dioxide generated by decomposing ethylene gas tends to stay in the chamber. However, when the degree of sealing in the warehouse is increased, moisture (water vapor) generated from the plant also tends to stay in the warehouse. Therefore, dew condensation is likely to occur on the side wall or the like in the cabinet. And when dew condensation occurs on the side wall or the like in the storage, the user may have to frequently clean the storage. Further, when liquid water (condensation water) generated by condensation adheres to food such as vegetables, the food may be easily deteriorated.

  In order to prevent dew condensation in the storage, it is also conceivable to absorb moisture (water vapor) in the storage and to install a hygroscopic member in the storage. However, the water collected by the hygroscopic member continues to accumulate as it is. For this reason, the user or the like must periodically drain the accumulated water, which is troublesome.

  This invention is made | formed in view of the said subject, The subject which this invention tends to solve is providing the refrigerator which can control humidity favorable, maintaining the freshness of the foodstuff in a warehouse.

As a result of intensive studies to solve the above problems, the present inventors have found the following findings. That is, the present invention includes a storage chamber, a lower container that is movable back and forth with respect to the storage chamber, a partition that is detachably provided on the lower container, and partitions the lower container into a front space and a rear space. An upper container placed on top of the lower container and in contact with or close to the upper end surface of the partition; and a moisture absorption / release device provided in the rear space of the lower container; The moisture absorption / release device is held by contacting a metal high heat conduction member that condenses moisture in the rear space on its surface to form dew condensation water, and cold air that cools the storage chamber. the moisture and a moisture absorption and release members of the resin fibers to be released to the cold air, the moisture absorption and release member is received condensed water flowing down from the high thermal conductivity member, receiving dew condensation water is the water absorption It is absorbed by the release member It is arranged at the lower end of said high thermal conductivity member to so that, above a high thermal conductivity member and the moisture absorption and release member is disposed opposite with a predetermined gap, facing the rear space of the high thermal conductivity member The high heat conductive member is arranged so that the high heat conductive member is cooled by the cold air coming into contact with the side opposite to the side.

In the space formed by these and the refrigerator main body 1, an ice making room, a quick freezing room, and a freezing room (all not shown) are formed. Similarly, the vegetable compartment door 6 can be pulled out toward the front side of the page. Furthermore, the vegetable compartment 100 (refer FIG. 2) is formed in the space comprised by this and the refrigerator main body 1. FIG.

  FIG. 2 is a top perspective view of the vegetable room 100 (an example of a storage room) in the refrigerator 10 of the present embodiment. In the vegetable compartment 100, the inner box 124 of the refrigerator main body 1 (see FIG. 1) constitutes the wall surface (left wall, right wall, and bottom wall) of the vegetable compartment 100, and the heat insulation located between the vegetable compartment 100 and the freezer compartment. The partition wall constitutes the upper wall of the vegetable room 100. In the vegetable compartment 100, a corrugated container 101 and an upper container 102 are accommodated so that they can be pulled out in the front-rear direction. On the back side of the vegetable room 100, a machine room for arranging a compressor (not shown) and the like outside the cabinet is formed. Therefore, the bottom wall is higher on the back side than on the front side. The lower container 101 is provided with a glass partition 103. Thereby, the lower container 101 is divided | segmented into two divisions (front side and back side). And the upper container 102 is arrange | positioned so that the division of the back side of the two divisions of the lower container 101 may be covered.

  FIG. 3 is a cross-sectional view taken along line AA in FIG. As described above, the inside of the lower container 101 is divided into two compartments, that is, the rear space 101A and the front space 101B by the partition 103. The partition 103 is sandwiched between a pair of partition locking portions 104 provided to face each other on the inner wall of the lower container 101.

  The lower container 101 is accommodated in the vegetable compartment 100 as described above. And the roller (not shown) provided in the side surface of the lower container 101 rolls the inside of the drawer rail 127 formed in the inner wall of the inner box 124 which comprises the left wall and the right wall of the vegetable room 100, and a vegetable room It is accommodated in 100 and pulled out from the vegetable compartment 100. Further, when the upper container 102 pulled out from the vegetable compartment 100 is pushed to the vegetable compartment 100 side, it is supported by a drawer rail 134 formed on the inner wall of the inner box 124. When the vegetable compartment door 6 is closed, the upper container 102 is supported by the upper edge of the lower container 101. In addition, by operating the handle 106 provided on the front side of the upper container 102, the upper container 101 can be easily pushed and pulled out.

  A resin-made shielding member 120 that covers a photocatalyst for decomposing ethylene gas in the rear space 101A to form carbon dioxide on the side wall inside the lower container 101, does not transmit light, or reduces transmittance. Is provided. This photocatalyst will be described later with reference to FIGS. Further, the back side wall inside the lower container 101 is provided with a moisture absorption / release device 112 for reducing the moisture (water vapor) in the rear space 101A to a predetermined amount or less and a cover 110 covering the front surface thereof. . Details of the transpiration cassette 112 will also be described later with reference to FIGS.

  FIG. 4 is an enlarged view of a portion B in FIG. As described above, the upper container 102 is disposed so as to cover the rear space 101A. At this time, on the front side of the upper container 102, the partition engaging portion 102 a provided on the front side bottom surface of the upper container 102 is positioned so as to be in contact with or close to the upper end surface 103 a of the partition 103. Note that a gap may be formed between the partition engaging portion 102 a and the upper end surface 103 a of the partition 103. In the present embodiment, a seal member such as packing is not provided on the lower surface on the front side of the upper container 102. However, the seal member may be partially provided.

  FIG. 5 is an enlarged view of a portion C in FIG. On the back side of the upper container 102, as shown in FIG. 5, the seal member 107 attached to the lower rear surface of the upper container 102 is in contact with the upper rear part of the lower container 101. Therefore, air flow is less likely to be performed on the back side of the upper container 102 than on the front side.

  The seal member 107 attached to the lower surface on the back side of the upper container 102 is not attached to the entire area of the upper container 102 in the left-right direction (see FIG. 2), but is attached to the left and right ends of the upper container 102. It is attached with a slight gap (see also FIG. 20). That is, in the present embodiment, the sealing member 107 is provided on the lower surface on the back side of the upper container 102, thereby increasing the degree of sealing in the rear space 101A. However, as described above, the seal member is not provided on the front side, and there is a portion where the seal member 107 is not provided on both the left and right sides of the back side. Therefore, the rear space 101A is in a completely sealed state. Instead, it is almost sealed.

  Note that the seal member 107 is not necessarily provided as long as air does not easily flow from the gap between the upper container 102 and the lower container 101. For example, a rib extending downward may be provided at the lower portion of the upper container 102 so that the gap between the upper container 102 and the upper end of the lower container 101 becomes small. Further, a rib extending upward may be provided on the upper part of the lower container 101, and the gap between the lower end of the upper container 102 and the lower container 101 may be reduced by this rib.

  Further, a cold air outlet (not shown) is formed on the wall surface of the vegetable room 100 or the heat insulating partition wall located between the vegetable room 100 and the freezer room. The air outlet is provided with cold air supply adjusting means (open / close damper) 141 (see FIG. 2) capable of controlling the supply of cold air for cooling the vegetable compartment 100. As a result, the cold air blown into the vegetable compartment 100 enters the rear space 101A to some extent and escapes from the front side. Furthermore, the humidity in the rear space 101A can be prevented from rising excessively, and condensation at unintended parts is prevented. This point will be further described in detail with reference to FIG. Note that the cold air supply adjusting unit 141 is not necessarily provided at the air outlet.

  FIG. 6 is a top perspective view from the front side of the lower container 101 provided in the refrigerator 10 of the present embodiment. The left inner wall of the lower container 101 is provided with the shielding member 120 and the partition locking portion 104. A partition locking portion (not shown) that holds the partition 103 together with the partition locking portion 104 provided on the left inner wall is also provided on the right inner wall of the lower container 101. Further, a cover 110 having ventilation portions 110a and 110b (see FIG. 12) through which air can pass is provided on the inner wall on the back side so as to cover a moisture absorption / release device 112 (not shown in FIG. 6).

  In addition, although the ventilation parts 110a and 110b formed in the cover 110 are configured by slits extending in the left-right direction in this embodiment, the present invention is not limited thereto, and is configured by slits extending in the vertical direction. Also good. Moreover, as a structure of a ventilation | gas_flowing part, well-known structures, such as the clearance gap shape which can pass air, and a hole shape, are not restricted to a slit.

  FIG. 7 is a top perspective view from the back side of the lower container 101 provided in the refrigerator 10 of the present embodiment. A moisture absorption / release device 112 is attached to the outside on the back side of the lower container 101 with an inclination with respect to the vertical direction. An opening not shown in FIG. 7 is formed in the side wall on the back side of the lower container 101, and a moisture absorption / release device 112 is attached so as to fit into the opening. The moisture absorption / release device 112 condenses the water vapor in the rear space 101A to form liquid water (condensation water), and evaporates the liquid water to discharge it as water vapor to the outside of the rear space 101A. It is. The configuration of the moisture absorption / release device 112 will be described with reference to FIGS.

  FIG. 8 is a perspective view from the front side of the moisture absorption / release device 112 provided in the refrigerator 10 of the present embodiment. As shown in FIG. 8, the moisture absorption / release device 112 is configured such that a flat metal plate 113 is disposed on the front side when attached to the lower container 101. Therefore, when the moisture absorption / release device 112 is attached to the opening of the lower container 101, the metal plate 113 faces the rear space 101A. By the metal plate 113, water vapor in the rear space 101A is condensed and liquid water (condensed water) is obtained. The frame 114 is a rectangular member capable of supporting and fixing each component of the moisture absorption / release device 112. Each side portion of the frame 114 can be detached independently.

  FIG. 9 is a perspective view from the back side of the moisture absorption / release device 112 shown in FIG. As shown in FIG. 9, the moisture absorption / release device 112 is configured such that the second frame 115 is disposed on the back side. The second frame 115 includes an opening (vent hole) 115a. In the present embodiment, the opening 115a has a configuration in which a plurality of circular holes are arranged. However, the shape, size, number, and the like of the holes are not particularly limited, and may be any configuration that allows air to pass therethrough. Accordingly, the moisture absorption / release member 116 (described later with reference to FIGS. 10 and 11) inside the moisture absorption / release device 112 can come into contact with air. Note that it is preferable to set the size and shape of the opening 115a in consideration of preventing the user from directly touching the inside of the moisture absorption / release device 112 from the opening 115a and improving the appearance design. .

  FIG. 10 is a view showing a state when the moisture absorption / release device 112 shown in FIG. 8 is opened. As shown in FIG. 10, the periphery of the metal plate 113 is supported by the first frame 151. A boundary portion between the first frame 151 and the second frame 115 is connected to each other so as to be rotatable (see an arrow d in FIG. 10). Accordingly, when the first frame 151 is rotated to the position overlapping the second frame 115 with the boundary as a base point, a plurality of engaging recesses 152 provided on the left and right of the first frame 151 at predetermined intervals are engaged. And the engagement pieces 153 located on the left and right of the corresponding second frame 115. Thereby, these are fixed in a state where the first frame 151 and the second frame 115 overlap. In addition, the periphery of the assembly in a state where the first frame 151 and the second frame 115 are overlapped and fixed is further supported and fixed by the frame 114 as described above.

  The moisture absorption / release device 112 includes a flat moisture absorption / release member 116 sandwiched between the metal plate 113 and the second frame 115. The moisture absorption / release member 116 is in contact with the cold air flowing outside the back side of the lower container 101 to release moisture (liquid) held by the moisture absorption / release member 116 into the cold air. The moisture absorption / release member 116 is disposed to face the metal plate 113 with a gap. An absorption piece 154 is integrally provided below the moisture absorption / release member 11. Details of the absorption piece 154 will be described later with reference to FIG.

  FIG. 11 is an enlarged view of the moisture absorption / release member 116 shown in FIG. In this embodiment, the moisture absorption / release member 116 is made of resin fibers. As an example of the resin fiber, PE fiber or PET fiber is knitted. Further, as an example, PE fibers are knitted in the vertical direction. That is, the fiber direction of the PE fiber is the vertical direction. Thereby, the movement of the water to an up-down direction is accelerated | stimulated more.

  The moisture absorption / release member 116 is opposite to the metal plate 113 (arranged side by side with the metal plate 113) and the absorption portion where the lower end surface of the metal plate 11 contacts when the moisture absorption / release device 112 is assembled. 116b. Among these, the discharge part 116 a comes into contact with cold air flowing outside the lower container 101. And the absorption part 116b supplies the received dew condensation water to the discharge | release part 116a while receiving the dew condensation water produced in the metal plate 113. FIG.

  The discharge part 116a and the absorption part 116b are integrally connected. Specifically, the discharge part 116a extends in the vertical direction, and the absorption part 116b connected to the discharge part 116a extends in the front-rear direction. In particular, the absorption part 116b is formed so as to extend from the lower end of the discharge part 116a toward the front side. As a result, when the moisture absorption / release device 112 is assembled using the moisture absorption / release member 116, the arrangement direction of the moisture absorption / release member 116 is uniquely determined, and misassembly is prevented.

  In addition, the discharge | release part 116a and the absorption part 116b may be comprised integrally, and the structure which arrange | positioned what was comprised separately and mutually contacted or adjoined may be sufficient. Further, the material of the emitting part 116a and the material of the absorbing part 116b may be the same or different. In addition, the extending direction of the emission part 116a and the absorption part 116b is not necessarily limited to the above-described direction, and the emission part 116a and the absorption part 116b may be configured to extend in the same direction or in different directions, respectively. Or a combination of curved surfaces.

  Further, a slit 116c is formed in the discharge portion 116a. Therefore, when the moisture absorption / release device 112 is attached to the lower container 101, the cold air that has entered the moisture absorption / release device 112 from the opening 115 of the moisture absorption / release device 112 enters the metal plate 113 in addition to the moisture absorption / release member 116. Will also come into contact. Thereby, cold air is also contacted from the side opposite to the side facing the rear space 101A, and condensation on the metal plate 113 in the rear space 101A is promoted. Further, since cold air comes into contact with both surfaces of the moisture absorption / release member 116, the release of condensed water from the moisture absorption / release member 116 is promoted.

  Moreover, the slit 116c formed in the discharge part 116a extends in the vertical direction. As a result, a large number of slits are secured, and cold air is reliably brought into contact with both sides of the discharge portion 116a. The slit 116c is not limited to the vertical direction, and may be a slit shape in the horizontal direction or a hole shape other than the slit shape.

  With reference to FIG. 12, a method for releasing moisture in the rear space 101 </ b> A by the moisture absorption / release device 112 will be described.

  FIG. 12 is a diagram illustrating an air flow in the vicinity of the moisture absorption / release device 112 in the rear space 101A in the refrigerator 10 of the present embodiment. As described above, when the moisture absorption / release device 112 is attached to the lower container 101, the metal plate 113 faces the rear space 101A. Therefore, the air in the rear space 101A comes into contact with the metal plate 113 through the upper slit 110a or the lower slit 110b formed in the cover 110 as shown by the solid arrow in FIG.

  Here, cold air for cooling the vegetable compartment 100 flows outside the back side of the lower container 101. Therefore, this cold air also flows on the back side of the metal plate 113 as shown by the broken line in FIG. Therefore, the metal plate 113 is also cooled by this cold air. Thereby, it becomes easy to condense on the metal plate 113, and the dew condensation in parts other than the metal plate 113 is suppressed. Then, the water condensed on the metal plate 113 flows down as a water droplet 117 by its own weight, and reaches the absorption portion 116b of the moisture absorption / release member 116.

  The water droplet 117 that has reached the absorption portion 116b diffuses inside the moisture absorption / release member 116 by capillary action. That is, the water droplet 117 that has flowed down to the absorption unit 116b diffuses throughout the absorption unit 116b. Then, the diffused water ascends the discharge portion 116a disposed to face the metal plate 113 and diffuses the discharge portion 116a. In particular, in the present embodiment, since the resin fibers are knitted in the vertical direction, moisture diffusion tends to occur upward.

  As described above, the metal plate 113 and the discharge portion 116a of the moisture absorption / release member 116 are disposed with a gap. Further, the moisture absorption / release member 116 is formed with a slit 116c. Therefore, the cold air flowing on the back side of the metal plate 113 flows so as to wrap around the discharge portion 116a. Accordingly, the moisture diffusing through the discharge part 116a is promoted to be released by contact with cold air. In this way, the moisture in the rear space 101A is sent from the vegetable compartment 100 to the heat exchanger (not shown) constituting the refrigeration cycle via the moisture absorption / release member 116. That is, the release of moisture is promoted when the moisture in the rear space 101A is equal to or greater than a predetermined amount.

  Further, as described above, the cover 110 is formed with the upper slit 110a and the lower slit 110b. The upper slit 110a has an inclination such that the air flow is directed upward. Since the upper slit 110a directed upward is provided on the upper side of the cover 110, it is difficult for the user to visually recognize the metal plate 113 when the user opens the rear space 101A. Thereby, design nature is improved.

  Further, the lower slit 110b has an inclination so that the air flow is downward. By providing the lower slit 110b directed downward on the lower side of the cover 110, when water drops adhere to the wall surface of the cover 110 (the surface facing the rear space 101A) and flow down, the rear space 101A It can suppress flowing down to the bottom. That is, the water droplets that have flowed down the wall surface of the cover 110 pass through the lower slit 110b and reach the absorption portion 116b of the moisture absorption / release member 116. As a result, water droplets adhering to the cover 110 are also absorbed and released by the moisture absorption / release member 116.

  In particular, in the present embodiment, the moisture absorption / release device 116 has an inclination on the back side on the upper side and on the front side on the lower side. Therefore, the moisture that flows down the surface of the cover 110 can be prevented from falling directly to the bottom surface, and can easily enter the lower slit 110b. Thereby, it is suppressed more that a water | moisture content adheres to the vegetable etc. in 101 A of back side spaces.

  Further, a water receiving portion 114 a as shown in the figure is provided on the inner bottom portion of the frame 114. The absorption part 116b of the moisture absorption / release member 116 is positioned above the water receiving part 114a. And the support part 155 extended upwards is provided in the water receiving part 114a. The support portion 155 supports the vicinity of the middle in the front-rear direction of the absorption portion 116b from below, so that the water receiving portion 114a for storing moisture is formed below the absorption portion 116b. As described above, the moisture dropped on the metal plate 113 is directly absorbed by the absorbing portion 116b. However, even if the moisture is not absorbed by the absorbing portion 116b, the unabsorbed moisture is stored in the water receiving portion 114a. It will be.

  Furthermore, as shown in FIGS. 10 and 11, the moisture absorption / release member 116 has a plurality of absorption piece portions 154 that extend partially below the absorption portion 116 b. In the assembled state shown in FIG. 12, the absorbent piece 154 is located in the space of the water receiving part 114a on the inner bottom part of the frame 114 (not shown in FIG. 12). For this reason, the water | moisture content stored by the water receiving part 114a without being absorbed by the absorption part 116b is absorbed through the absorption piece part 154, and the movement to the discharge | release part 116a is promoted. That is, with this configuration, it is possible to suppress the moisture dropped from the metal plate 113 from leaking from the moisture absorption / release device 112 into the lower container 101 or the vegetable compartment 100.

  FIG. 13 is a perspective view of the partition 103 provided in the lower container 101 in the refrigerator 10 of the present embodiment. The partition 103 includes a rectangular resin frame member 103a and a rectangular glass plate 103b surrounded by the frame member 103a. The partition 103 is supported and fixed in the lower container 101 by inserting the frame member 103b into the partition locking portion 104 shown in FIG.

  Moreover, the recessed part 103c is formed toward the back direction at the lower end of both the left and right sides of the frame member 103b. Therefore, when the partition 103 is inserted into the partition locking portion 104, the direction of the partition 103 (the direction between the front side and the back side and the direction in the vertical direction) is determined. Thereby, the incorrect assembly of the partition 103 is prevented. This point will be described in more detail with reference to FIGS.

  FIG. 14 is a diagram illustrating a state in which the partition 103 is attached in the refrigerator 10 of the present embodiment. The partition 103 is attached so as to be sandwiched between a pair of partition locking portions 104 provided on the left and right side surfaces of the lower container 104. That is, the partition plate 104 is attached in the lower container 101 by inserting the partition plate 104 from above between the pair of partition locking portions 114.

  15 is a cross-sectional view taken along the line DD of FIG. As described above, the frame member 103b of the partition 103 is formed with the recess 103c toward the back surface. On the other hand, when the partition 103 is attached as shown in FIG. 15, a convex surface 104a is formed inside the set of partition locking portions 104 so as to face the recess 103c. By doing in this way, when the partition 103 is attached, it is prevented that the partition 103 is attached with the front side and the back side being reversed. Further, the partition 103 is prevented from being inserted into the partition locking portion 104 with the vertical direction and the front-rear direction reversed.

  In addition, the structure of the partition 103 is not limited to the structure which has the recessed part 103c. Therefore, for example, by making at least one of the left and right or the front and rear of the frame member 103a an asymmetrical or irregular shape, it is possible to prevent erroneous assembly of the partition 103.

  Further, on the side surface of the frame member 103a (the surface facing the inner wall of the lower container 101 sandwiched between the set of partition locking portions 104), the width in the left-right direction of the partition 103 becomes narrower as it goes downward. A slope is formed. On the other hand, on the inner wall of the lower container 101 sandwiched between the pair of partition locking portions 104, the width in the left-right direction of the lower container 101 becomes narrower toward the lower side corresponding to the width of the frame member 103a to be inserted. The slope is formed so as to be. With these configurations, when the partition 103 is to be installed in the lower container 101 with the partition 103 upside down, the partition 103 is wider toward the upper side, so the partition 103 is below the predetermined height position of the lower container 101. Cannot be incorporated. Thereby, the upper and lower incorrect assembly of the partition 103 can be prevented.

  FIG. 16 is an exploded perspective view showing a part including a photocatalyst for decomposing ethylene gas in the rear space 101A of the refrigerator 10 of the present embodiment. As described above, the shielding member 120 that does not transmit light or has reduced transmittance is attached to the inner wall of the lower container 101. As shown in FIG. 16, the shielding member 120 is attached so as to cover the slit 101 a formed on the wall surface of the lower container 101. In addition, although it is preferable to form the slit 101a from the viewpoint of ensuring the strength of the lower container 101 more reliably, the opening may be formed without providing the slit 101a.

  On the other hand, the glass plate 122 is arrange | positioned so that it may fit in the outer frame 156 of the outer side (left side) of the slit 101a. The glass plate 122 is coated with a photocatalytic material such as titanium oxide on the side (right side) facing the rear space 101A. A light transmissive resin member 121 is disposed so as to cover the glass plate 22. The resin member 121 is fixed to the outer wall of the lower container 101 by fastening members 123 such as screws and locking claws.

  FIG. 17 is a cross-sectional view showing the vicinity of a portion including a photocatalyst that decomposes ethylene gas in the rear space 101A of the refrigerator 10 of the present embodiment. The shielding member 120 is attached to the inner wall of the lower container 101 such that the longitudinal direction thereof is directed in the vertical direction, but is not limited thereto, and may be attached so that the longitudinal direction thereof is directed in the left-right direction.

  Further, a gas flow part 120 a is formed at the front side end and the back side end of the shielding member 120. A gap is formed between the shielding cover 120 and the slit 101a. That is, a gap is formed between the shielding cover 120 and the glass plate 122 (not shown in FIG. 17, refer to FIG. 16) disposed on the outside (left side) of the slit 101a. By doing so, the air in the rear space 101A can reach the glass plate 122 coated with the photocatalyst through this gap.

  In addition, in FIG. 17, the gas circulation part 120a is provided in two places, the top and bottom, respectively, at the front end and the back end, but not limited to this, the front end and the back end are provided. The structure provided in one place at least in any one of the edge parts may be sufficient. In addition to the front-side end and the back-side end, the gas circulation part 120a may be provided on the surface facing the rear space 101A of the shielding member 120.

  FIG. 18 is a perspective view showing the vegetable compartment 100 in which the lower container 101 is accommodated in the refrigerator 10 of the present embodiment. An LED cover 125 that covers the LED board 126 (not shown in FIG. 18, see FIG. 19) is disposed on the inner wall on the left side of the inner box 124 that constitutes the wall surface of the vegetable compartment 100. The LED cover 125 is made of a light transmissive material, and is attached so that the longitudinal direction thereof is in the vertical direction, like the shielding cover 120. An LED (not shown) is mounted on the LED substrate 126, and a voltage is applied to the LED so that the LED emits light. Although not shown in FIG. 18, the LED board 126 is prevented from coming into contact with the urethane foam described later by attaching the storage member 128 from the outside of the inner box 124.

  Further, as described above, inside the inner box 124, as described above, the drawer rail 127 that slidably supports the end of the lower container 101 and the end of the upper container 102 are slidably supported. The drawer rail 134 to be formed is formed. And the LED board 126 etc. are arrange | positioned under the drawer rail 127, and the dead space which exists under the drawer rail 127 is used effectively.

  In the present embodiment, the LED board 126 and the like are disposed below the drawer rail 127 when the drawer rail 127 is positioned upward in the vertical direction of the inner box 124 surface, but the present invention is not limited to this. . For example, when the drawer rail 127 is positioned on the lower side in the vertical direction of the inner box 124 surface, the LED board 126 and the like may be disposed above the drawer rail 127. With this configuration, the dead space below or above the drawer rail can be used effectively.

  FIG. 19 is a diagram showing a relative positional relationship between the LED substrate 126 and the glass plate 122 when the lower container 101 is accommodated in the vegetable compartment 100. When the lower container 101 is accommodated in the inner box 124, the photocatalyst and the like attached to the lower container 101 and the LED substrate 126 attached to the inner box 124 face each other. That is, the lower container 101 is accommodated in the inner box 124 so that the LED cover 125 and the resin member 121 face each other.

  As described above, both the LED cover 125 and the resin member 121 are made of a light transmissive material. Therefore, the light emitted from the LEDs on the LED substrate 126 passes through the LED cover 125 and the resin member 121 and reaches the glass plate 122 coated with the photocatalyst. The light that reaches the glass plate 122 passes through the glass plate 122 and is irradiated to the photocatalyst applied to the rear space 101A side. As a result, the photocatalyst is activated, and the ethylene gas contained in the air in the rear space 101A is decomposed into carbon dioxide, so that the freshness of vegetables and the like is maintained, or a decrease in freshness is suppressed.

  Moreover, since the shielding member 120 which suppressed light transmission is attached to the position facing LED, it is suppressed that the light which permeate | transmitted the slit 101a is irradiated to the vegetables etc. in 101 A of back side spaces. Thereby, growth of vegetables etc. by light irradiation to vegetables etc. is controlled.

  FIG. 20 is a diagram illustrating an air flow in the vegetable compartment 100 of the refrigerator 10 of the present embodiment. In FIG. 20, air flows as shown by a thick solid line as an example. Specifically, the air flows into the vegetable compartment 100 through the air outlet (cold air supply adjusting means 141) provided on the upper right back side. And the inflowed air is sent to the heat exchanger (not shown) which comprises a freezing cycle from the vegetable compartment 100 through the suction inlet (not shown) provided in the lower left front side.

  In addition, although the relative arrangement | positioning of a blower outlet, a suction inlet, and the water | moisture-content absorption / release apparatus 116 is not restricted to the example of illustration, it is preferable that the water | moisture-content absorption / release apparatus 116 is arrange | positioned in the blower outlet vicinity. For example, the moisture absorption / release device 116 may be configured to be provided on any one of the left wall, the right wall, the bottom wall, or the partition 103 constituting the rear space 101A of the lower container 101. When the upper space 102B is covered with the upper container 102 to form a relatively airtight space, the moisture absorption / release device 116 may be disposed on the front wall of the lower container 101.

  Here, the cold air flowing into the vegetable compartment 100 from the air outlet is at a low temperature. Therefore, due to this influence, the wall surface of the lower container 101 or the upper container 102 constituting the rear space 101A (or the front space 101B) that is relatively airtight in the vicinity of the air outlet becomes a condition where condensation is likely to occur. Therefore, if the moisture absorption / release device 116 is disposed in the vicinity of the air outlet, moisture at the position of the rear space 101A (or the front space 101B) that is likely to condense due to overcooling can be absorbed. Release efficiency is improved.

  As described above, the seal member 107 is fixed to the lower surface on the back side of the upper container 102 (see FIG. 5 and the like). Therefore, in the space formed between the upper container 102, the lower container 101, and the partition 103 (that is, the rear space 101A), the airtightness is relatively improved. However, if the airtightness increases, the indoor humidity is likely to increase due to water vapor generated from indoor vegetables and the like. Therefore, in the present embodiment, the seal member 107 fixed to the lower surface on the back side of the upper container 102 does not extend over the entire area in the left-right direction on the lower surface of the upper container 102, and is provided with portions that are not provided on the left and right ends. Yes.

  Thereby, the cold air from the air outlet enters the rear space 101A from a portion where the seal member 107 in the vicinity of the air outlet of the cold air is not provided. Here, on the front side of the rear space 101A, no seal member is provided between the partition 103 and the upper container 102 thereon. For this reason, the cool air is relatively easy to pass on the front side than on the back side. Further, gaps are formed between the right and left walls of the upper container 102 and the lower container 101, and between the vicinity of the bottom corner of the upper container 102 and the lower container 101, respectively.

  In these configurations, the cool air blown from the upper rear side of the vegetable compartment 100 flows into the rear space 101A from the vicinity of the right bottom corner of the upper container 102 that is in front of the position where the cool air is blown. The cold air that has flowed into the rear space 101A escapes from the vicinity of the upper end of the right wall of the lower container 101 to the outside of the rear space 101A, and passes between the right wall of the upper container 102 or the lower container 191 and the right wall of the inner box 124. It flows from the rear to the front and travels from the front suction port to a heat exchanger (not shown).

  Further, a part of the cold air blown from the upper rear side of the vegetable chamber 100 flows from the right side to the left side along the back wall of the upper container 102, and in the rear space 101 </ b> A from the vicinity of the bottom corner on the left side of the upper container 102. Flow into. This cold air also flows from the vicinity of the upper end of the left wall of the lower container 101 to the outside of the rear space 101A, and flows from the rear to the front between the left wall of the upper container 102 or the lower container 191 and the left wall of the inner box 124. From the front suction port, it goes to the heat exchanger (not shown).

  Here, the photocatalyst that decomposes the ethylene gas in the rear space 101A into carbon dioxide is provided at a position away from the outlet. In the present embodiment, the air outlet is disposed on the rear right side of the vegetable compartment 100, and the photocatalyst is disposed on the left wall surface of the vegetable compartment 100. The temperature at a position away from the air outlet is relatively higher than the temperature at a position near the air outlet. Therefore, in the rear section 101A, a vegetable placed in a place where the temperature is high is relatively easy to release ethylene gas compared to a vegetable placed in a place where the temperature is low. Therefore, the ethylene gas is decomposed more efficiently by attaching the photocatalyst to such a relatively high temperature place.

  FIG. 21 is a diagram illustrating a state in which urethane foam is injected into the side portion of the refrigerator 10 of the present embodiment. FIG. 21 is a side view of the refrigerator 10, but the outer wall (outer box) of the refrigerator body 1 is omitted for convenience of explanation. A heat insulating material 130 made of urethane is provided on the side surface of the refrigerator 10.

  The urethane constituting the heat insulating material 130 is formed by solidifying urethane foam. Specifically, in a state where the front side of the refrigerator 10 is tilted vertically downward, the urethane foam is formed from the inlet 131 that is formed on the back side of the refrigerator 10 and communicates with the space in which the hard urethane foam is filled and foamed. It is injected into the space. At this time, the urethane foam is injected in the direction of the dashed arrow shown in FIG. Therefore, the urethane foam injected from the inlet 131 flows vertically downward (toward the front side of the refrigerator 10). Then, urethane foam is gradually accumulated in the space.

  While the urethane foam is being injected, the interface (liquid level) of the urethane foam in the space gradually rises. Here, the housing member 128 that houses the LED board 126 is attached to the inner box 124 so as to face the space. In the present embodiment, the housing member 128 that houses the LED board 126 is disposed so as to avoid the projection position in the front-rear direction of the injection port 131 of the urethane foam. Therefore, when the urethane foam is injected, the housing member 128 that houses the LED substrate 126 is inhibited from inhibiting the flow of the urethane foam. Therefore, it is possible to sufficiently fill and foam the urethane foam without any spots up to the upper side (back side) of the storage member 128.

  Further, a vacuum heat insulating material is disposed as the heat insulating material 130 in a space filled with foamed urethane foam (rigid urethane foam). A general vacuum heat insulating material is configured by covering a fiber laminate such as glass wool or resin with an outer packaging material and sealing the inside of the outer packaging material in a reduced pressure state. Therefore, the heat insulation performance tends to be higher than that of urethane foam. Moreover, since the vacuum heat insulating material has high heat insulating performance, the thickness and the filling amount of the heat insulating material can be reduced by using the vacuum heat insulating material and the urethane foam together as compared with the case of using the urethane foam alone. .

  Therefore, in this embodiment, a vacuum heat insulating material is disposed at a position facing the storage member 128 that stores the LED substrate 126. Thereby, in the vicinity of the storage member 128, the thickness of the urethane foam is thinner than that of the other part (that is, the flow space of the urethane foam is narrower than that of the other part), but the heat insulation performance is improved by the vacuum heat insulating material. The decrease can be suppressed.

  FIG. 22 is a perspective view from the front side showing another embodiment of the moisture absorption / release device 112 attached to the refrigerator 10 of the present embodiment. In the embodiment described above, the moisture absorption / release device 112 is configured such that the metal plate 113 and the moisture absorption / release member 116 face each other. However, in another embodiment of the moisture absorption / release device 112, the metal plate 113 and the moisture absorption / release member 116 are arranged on the left and right in a front view. Specifically, as illustrated in FIG. 22, the metal plate 113 is disposed on the right side of the inner back surface of the lower container 101 so as to face the rear space 101 </ b> A.

  FIG. 23 is a rear view showing another embodiment of the moisture absorption / release device 112 attached to the refrigerator 10 of the present embodiment. As shown in FIG. 23, the moisture absorption / release member 116 faces the outside of the lower container 101 and is disposed on the right side of the outer back surface of the lower container 101.

The metal plate 113 and the moisture absorption / release member 116 arranged on the left and right in front view are connected through a dew condensation water channel (not shown in FIG. 23 ) that communicates the inside and outside of the rear space 101A. Accordingly, the water droplet 117 (see FIG. 12) generated on the surface of the metal plate 113 reaches the moisture absorption / release member 116 attached to the outer wall of the rear space 101A through the condensed water flow path. The condensed water that has reached the moisture absorption / release member 116 diffuses in the moisture absorption / release member 116 and is released to the cold air flowing outside. Even in this case, the humidity in the rear space 101A is well adjusted.

  While the present embodiment has been described with reference to the drawings, the present embodiment is not limited to the above contents. Therefore, various modifications are included in the present invention. That is, the above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to one having all the configurations described.

  For example, a metal plate (for example, aluminum, iron, stainless steel, etc.) is used in the above example as the high heat conductive member that condenses moisture in the rear space 101A to form dew condensation water, but a material other than the metal plate may be used. For example, a resin material etc. are mentioned. The shape of the high heat conductive member is not limited to a flat plate shape, and may be any shape.

  Further, for example, the resin fiber is used in the above example as the moisture absorption / release member that releases the retained moisture (condensation water) to the cold air, but is not limited thereto. For example, a porous material, sponge or the like can be applied in a desired shape. However, normally, if the thickness of the moisture absorption / release member is increased, the amount of water retained increases, so that moisture can be absorbed and released more efficiently.

  Furthermore, in the above example, the metal plate 113 and the absorbing portion 116b constituting the moisture absorption / release member 116 are arranged in contact with each other, but these do not have to be in contact with each other. That is, as long as the dew condensation water on the surface of the metal plate 113 is supplied to the absorber 116b, any form may be used.

  Further, the metal plate 113 is arranged with an inclination with respect to the horizontal direction so that the dew condensation water generated on the surface of the metal plate 113 flows down by its own weight. What is the degree of this inclination? May be. That is, although it is preferable to attach as shown in the drawing if the mounting location and the inclination are considered comprehensively, for example, it may be attached in the vertical direction (inclination of 90 ° with respect to the horizontal direction). Further, the mounting position of the metal plate 113 is not limited to the illustrated location.

  Furthermore, although it is preferable that a predetermined gap is provided between the metal plate 113 and the moisture absorption / release member 116 as described above, the degree of the gap may be any. Usually, if the gap becomes large, water can be released more sufficiently. In addition, by bringing a sufficient amount of cool air into contact with the metal plate 113, the metal plate 113 can be cooled more sufficiently to promote condensation on the surface of the metal plate 113 in the rear space 101A. . Further, even if there is no gap, since cold air contacts the moisture absorption / release member 116, the metal plate 113 arranged side by side with the moisture absorption / release member 116 is cooled, causing condensation on the surface of the metal plate 113. be able to.

  In the above example, the metal plate 113 and the moisture absorption / release member 116 are both flat. However, these shapes are preferably flat, but are not limited to flat. Moreover, although these were arrange | positioned facing or left and right, the form of arrangement | positioning is not restricted to these.

  In addition, although glass is used as the partition 103 in the above example, a material other than glass may be used. For example, a resin material and a metal material are mentioned. That is, the partition 103 may be made of a material having a predetermined rigidity.

  Furthermore, although the vegetable room 100 was mentioned as a storage room where humidity is adjusted in the said example, another storage room may be sufficient.

  In addition to these, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of another embodiment can be added to the configuration of one embodiment. is there. Furthermore, other configurations can be added, deleted, replaced, etc., for a part of the configurations of each embodiment.
