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

  FIG. 1 is a front view of the refrigerator 10 of the present embodiment. The refrigerator 10 shown in FIG. 1 includes a refrigerator compartment left door 2, a refrigerator compartment right door 3, an ice making room door 4a, a rapid freezing room door 4b, a freezing room door 5, and a vegetable room on the front of the refrigerator body 1. The door 6 is provided. The cold storage room left door 2 is rotatable in the front side of the drawing by the upper hinge 7a and the lower hinge 8a. Furthermore, the refrigerator compartment right door 3 is rotatable in the front side of the drawing by the upper hinge 7b and the lower hinge 8b. That is, the cold storage room left door 2 and the cold storage room right door 3 are provided so as to be capable of double opening, and a cold storage room (not shown) is formed in the space formed by these and the refrigerator main body 1.

  In addition, the ice making room door 4a, the rapid freezing room door 4b and the freezing room door 5 can be pulled out in the front side of the drawing. And, 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 respectively formed. Similarly, the vegetable compartment door 6 can be pulled out in the front direction of the drawing. Furthermore, a vegetable room 100 (a storage room, see FIG. 2) is formed in a space formed by this and the refrigerator main body 1.

  FIG. 2 is a perspective view of the lower container 101 to which the upper container 102 is attached in the refrigerator 10. In the vegetable compartment 100, the inner box 124 of the refrigerator main body 1 (see FIG. 1) constitutes the wall (left wall, right wall and bottom wall) of the vegetable compartment 100. In addition, a vegetable container cover 105 (see FIG. 3) disposed above the vegetable compartment 100 constitutes the upper wall of the vegetable compartment 100. Therefore, in the vegetable compartment 100, the sealing property of the inside of each of the lower vessel 101 and the upper vessel 102 is secured to some extent.

  In the vegetable compartment 100, the lower container 101 (storage container) and the upper container 102 (storage container, inner container) are accommodated in the front side and the back side (hereinafter sometimes referred to as "in the front-rear direction") ing. However, in the present embodiment, even if the lower container 101 is moved in the front-rear direction, the position of the upper container 102 in the lower container 101 does not change. However, although the details will be described later, when the user operates the lock handle 106 (see FIG. 8), the upper container 102 can also be pulled out to the front side.

  On the back side of the vegetable compartment 100, a machine compartment (not shown) for forming a compressor (not shown) or the like outside the storage compartment is formed. Therefore, the bottom wall is higher on the back side than on the front side. In addition, the lower container 101 is provided with a glass partition 103. As a result, the lower container 101 is divided into two sections (a front space 101B on the front side, a rear lower space 101A on the rear side, and a rear upper space 101C, both not shown in FIG. 2). The upper container 102 is disposed so as to cover the space on the back side of the two sections of the lower container 101.

  FIG. 3 is a perspective view of the vegetable compartment 100 in which the vegetable container cover 105 (cover member) is disposed in the refrigerator 10. The vegetable container cover 105 is disposed so as to cover the upper opening of the lower container 101 and the upper container 102 (see FIG. 4; both are not shown in FIG. 3). The vegetable container cover 105 is arranged above the lower container 101 when the lower container 101 is accommodated in the refrigerator 10. Therefore, when the lower container 101 is completely pulled out of the refrigerator 10, the vegetable container cover 105 remains inside the refrigerator 10, and the inside of the lower container 101 is opened to the outside.

  The vegetable container cover 105 is made of a light-transmitting resin. A knurl (a plurality of grooves extending from the front side to the back side) 105a is formed on the front side of the upper surface of the vegetable container cover 105. Then, when the user pulls out the lower container 101 and the upper container 102 to the front side and uses them, the light from the LED illumination attached to the outside of the vegetable compartment 100 and above is transmitted through the knurled 105 a The inside of the lower container 101 and the upper container 102 is irradiated. As described above, since the knurled 105 a is formed of a plurality of grooves, light incident on the knurled 105 a is diffused. Further, since the knurls 105a are formed by a plurality of grooves, the surface area is large. Therefore, a wide range is irradiated, suppressing generation | occurrence | production of a shadow.

  In addition, a transpiration board 105 b is disposed on the lower surface of the vegetable container cover 105 (that is, the surface facing the inside of the vegetable compartment 100). Furthermore, on the upper surface of the vegetable container cover 105, a plurality of communication holes 105c (inner and outer communication holes) that communicate the inside and the outside of the vegetable chamber 100 are formed. Details of these points will be described later with reference to FIG. 9 and FIG.

  A cold air outlet (not shown) is formed in the wall of the vegetable compartment 100 or in the heat insulating partition wall located between the vegetable compartment 100 and the freezing compartment. And the cold air supply adjustment means 141 which can control supply of the cold air which cools the vegetable compartment 100 is provided in this blower outlet. As a result, the cold air blown out to the vegetable room 100 slightly intrudes into the rear space 101A (see FIG. 4), and is removed from the front side. Furthermore, it is possible to prevent the humidity in the back side space 101A from excessively rising, and to prevent condensation at an unintended site.

  FIG. 4 is a cross-sectional view taken along line AA of FIG. In addition, in FIG. 4, the vegetable compartment door 6 shown in FIG. 1 is also shown collectively. The lower container 101 is divided into three spaces of a rear lower space 101A, a front space 101B, and a rear upper space 101C. Among these, the lower rear space 101A is formed by dividing the lower vessel 101 by the partition 103 disposed inside the lower vessel 101 and the lower surface of the upper vessel 102. Further, the front space 101 B is formed by dividing the lower container 101 by the side surface on the front side of the upper container 102, the partition 103 and the vegetable container cover 105. The rear upper stage space 101C is formed by dividing the lower vessel 101 by the upper vessel 102 and the vegetable vessel cover 105.

  Of the respective spaces, on the back side of the lower rear space 101A, the respective spaces inside the lower vessel 101 (ie, the lower rear space 101A, the front space 101B, and the rear upper space 101C) A transpiration cassette 112 is disposed to control the humidity in the space. The details of the transpiration cassette 112 will be described later with reference to FIG.

  Further, a communication hole 102a (space communication hole) for communicating the rear lower space 101A (first space) with the rear upper space 101C (second space) is formed on the bottom surface of the upper container 102. . Thereby, dehumidification of both the back side lower stage space 101A and the back side upper stage space 101C becomes possible.

  FIG. 5 is a perspective view from the front side of the upper container 102. The lock handle 106 (support fixing and releasing mechanism) disposed on the front side of the upper container 102 normally operates the upper container 102 by operating the upper container 102 supported and fixed inside the lower container 101 by the user. It is possible to move back and forth. The lock handle 106 is configured to include a pressing portion 106 a that allows the upper container 102 to move to the front side by being pressed, and a recessed portion 106 b that is slightly recessed on the front upper end of the upper container 102. Be done. Then, the user holds the depressed portion 106 b and presses the holding portion 106 a with the thumb or the like of the hand holding the pressed portion 106 a, thereby releasing the support and fixation of the upper container 102 in the lower container 101. And thereby, the upper stage container 102 becomes movable in the front-back direction.

  Further, below the front side of the lock handle 106, three spaces of a rear lower lower space 101A, a front lower space 101B, and a rear upper upper space 101C (hereinafter, these spaces are A communication hole 106 c (space communication hole) is formed, which collectively communicate “each space”. Further, inside the lock handle 106, a platinum catalyst 118 (see FIG. 8 (b)) is accommodated at a position where it can contact air in each space. Therefore, the air taken into the lock handle 106 through the communication hole 106 c comes in contact with the platinum catalyst 118, and then the air in contact with the platinum catalyst 118 is supplied to each space. Thereby, the air in the front space 101B reaches the transpiration board 105b (see FIG. 10) in the rear upper stage space 101C and the dew condensation surface 101a (see FIG. 16) formed on the back side in the rear lower stage space 101A. be able to. Therefore, control of the humidity of the air in front side space 101B is attained.

  FIG. 6 is a perspective view from the back side of the upper container 102. A communication hole 106 d is formed in the lower part of the back side of the lock handle 106 to connect the spaces with each other through the inside of the lock handle 106. As in the case of the communication hole 106c, the air taken into the lock handle 106 through the communication hole 106d contacts the platinum catalyst 118, and thereafter, the air in contact with the platinum catalyst 118 is supplied to each space. It will be. The communication hole 106 d faces the rear upper stage space 101 C through a hole 102 b formed on the front side surface of the upper vessel 102.

  FIG. 7 is a perspective view from the lower side of the upper container 102. Below the lock handle 106, there are also formed communication holes 106e that communicate three spaces of the rear lower lower space 101A, the front space 101B, and the rear upper upper space 101C via the inside of the lock handle 106. . As in the case of the communication holes 106c and 106d, the air taken into the lock handle 106 through the communication hole 106e contacts the platinum catalyst, and thereafter, the air in contact with the platinum catalyst is supplied to each space. It will be. The communication hole 106 e faces the rear lower space 101 A through a hole 102 c formed in the bottom surface of the upper container 102.

  FIG. 8 shows each member constituting the lock handle 106, (a) is a perspective view from the back side, (b) is an exploded perspective view, and (c) is a B- in (a). It is a B line sectional view. In addition, in FIG.8 (c), in order to simplify illustration, illustration of a part of mechanism for releasing a lock | rock (the support fixation of the upper stage container 102) is abbreviate | omitted.

  As shown in FIG. 8A, the lock handle 106 has a catalyst cover 106f having a communication hole 106d, a back of the handle case 106g to which the catalyst cover 106f is attached, and a front of the handle case attached to the front of the handle case 106g. 106 h and a handle lever 106 j integrally formed with the pressing portion 106 a (see FIG. 5). Then, as shown in FIG. 8B, when the catalyst cover 106f is removed from the lock handle 106, a platinum catalyst 118 is disposed inside the lock handle 106 so as to extend in the left-right direction. The platinum catalyst 118 is disposed inside the lock handle 106 so as to avoid a mechanism (not shown) for unlocking the lock handle 106.

  In FIG. 8C, thick arrows indicate the air flow direction. As shown in FIG. 8C, the platinum catalyst 118 can be in contact with the air in each space through the communication holes 106c, 106d and 106e. Further, although not shown by the arrows, the air in each space is also supplied to another space without contacting the platinum catalyst 118.

  Here, the platinum catalyst 118 will be described. Unlike the photocatalyst, the platinum catalyst 118 is a catalyst that decomposes ethylene and trimethylamine contained in the air in each space even without light such as an LED. The decomposition of ethylene by the platinum catalyst 118 generates carbon dioxide and water vapor. And since the generated carbon dioxide is supplied to each space through the communicating hole, the pores of the vegetables stored in each space are closed, the respiration of the vegetables is suppressed, and the nutrient component by respiration is reduced or dried. Can be kept, so the freshness of vegetables is maintained for a long time. The installation location of the platinum catalyst 118 is not limited to the inside of the lock handle 106, and a catalyst storage portion may be provided on at least one wall surface that divides each space, and the platinum catalyst 118 may be stored in the catalyst storage portion. In this case, communication holes communicating with the respective spaces are also formed in the catalyst storage portion. Moreover, while providing a catalyst accommodating part in the wall surface in any one of each space, the structure which forms a communicating hole in the wall surface which divides each space may be sufficient.

  In addition, when carbon dioxide is dissolved in water present on the surface of a vegetable or the like stored in the vegetable room 100, the surface of the vegetable or the like becomes acidic. However, when trimethylamine having alkalinity is generated when it is dissolved in water, trimethylamine is also dissolved in water present on the surface of the vegetable, so that the acidified vegetable surface is neutralized by the dissolution of carbon dioxide. However, in the refrigerator 10, the trimethylamine is decomposed by the platinum catalyst 118, whereby the surface of the vegetables and the like stored in the vegetable compartment 100 becomes acidic, and the growth of microorganisms on the surface of the vegetables is suppressed.

  The platinum catalyst 118 in the refrigerator 10 is in the form of pellets, and is packed in a bag and accommodated in the lock handle 106. Thereby, the pellet-like platinum catalyst 118 is appropriately mixed in the bag when the upper-stage container 102 is pulled out and stored. Therefore, air can be prevented from contacting the pellets from one direction only, and the catalytic function is maintained. In addition, you may use not only the platinum catalyst 118 but another transition metal catalyst. In the refrigerator 10, silica (mesoporous silica) having pores is used as the transition metal catalyst, and fine particles of transition metals such as platinum and ruthenium are supported inside the pores.

  FIG. 9 is a perspective view from above of the vegetable container cover 105. FIG. As described above, the knurling 105 a is formed on the front upper surface of the vegetable container cover 105. Light from LED lighting (not shown) is applied to the inside of the vegetable compartment 100 from the outside of the knurled 105 a. In addition, inside and outside of the upper rear space 101C formed between the upper container 102 (not shown in FIG. 9) disposed below the vegetable container cover 105 and the vegetable container cover 105 in the vegetable container cover 105 A plurality of communicating holes 105c communicating with each other are formed. In the refrigerator 10, the number of the communication holes 105c is eighteen and is formed including the vicinity of a cold air return port (not shown) formed on the back right side of the vegetable compartment 100.

  FIG. 10 is a perspective view from below of the vegetable container cover 105, where (a) is an overall view thereof and (b) is an enlarged view of a portion C of (a). FIG. 10A shows a state in which the vegetable container cover 105 is observed from below the front side of the vegetable container cover 105. As shown to Fig.10 (a), the transpiration board 105b (water absorption and release member) is arrange | positioned on the lower surface (surface which faces the inside of the upper stage container 102) of the vegetable container cover 105. As shown in FIG. The transpiration board 105b is a flat plate-like member formed by knitting resin fibers such as PET fibers, and is a material that allows air to pass but absorbs liquid moisture. And the moisture absorbed is transpirationable (released) with respect to the air.

  As shown in FIG. 10 (b), a rib 105d is formed on the lower surface of the vegetable container cover 105 so as to face the communication hole 105c in the vertical projection of the communication hole 105c communicating the inside and the outside of the vegetable compartment 100. There is. And the transpiration board 105b is hold | maintained on the lower surface of the vegetable container cover 105 by inserting the transpiration board 105b in the space 105e formed between the communicating hole 105c and the rib 105d. Since the rib 105d is provided at the location where the communication hole 105c is formed and the strength weakens, the vegetable container cover 105 can be effectively reinforced. Furthermore, since the rib 105 d prevents the transpiration board 105 b from being exposed directly upward, the handleability is improved. Further, by holding the transpiration board 105b in the space 105e, the communication hole 105c is positioned under the vertical projection of the transpiration board 105b, and the communication hole 105c is closed by the transpiration board 105b. Thus, while the air containing moisture inside the lower container 101 and the upper container 102 is discharged to the outside of the vegetable compartment 100 through the communication hole 105 c, the vegetable compartment 100 from the outside of the vegetable chamber 100 through the communication hole 105 c. Direct entry of cold air into the interior of the

  In addition, when the air inside the rear upper stage space 105C contacts the vegetable container cover 105, the water contained in the air may condense on the vegetable container cover 105 to generate condensation water. However, the generated dew condensation water is absorbed by the transpiration board 105 b disposed over the entire area above the upper vessel 102. Therefore, the drop of the condensed water to the rear upper stage space 10C is suppressed.

  FIG. 11 is a side view of the vegetable container cover 105. In FIG. 11, the lower container 101 and the lower container 102 disposed below the vegetable container cover 105 are shown by imaginary lines. The transpiration board 105 b is attached to the lower surface of the vegetable container cover 105 facing the inside of the upper container 102. Further, although not shown in FIG. 11, cold air for cooling the vegetable compartment 100 flows above the vegetable container cover 105. Therefore, the flowing cold air flows so as to lick the transpiration board 105b exposed from the communication hole 105c. As a result, the liquid water absorbed by the transpiration board 105 b is released as cold water that flows as water vapor. That is, the moisture in the vegetable compartment 100 is absorbed by the transpiration board 105b, and the moisture absorbed is released to the outside of the vegetable through the communication hole 105c. Therefore, the transpiration board 105 b absorbs water excessively, and the water droplets are prevented from dripping into the upper container 102.

  FIG. 24 is a perspective view when the vegetable container cover 105 is viewed from below before attaching the transpiration board 105 b. As shown in FIG. 24, ribs 105 d are formed on the front side and the rear side on the back surface of the vegetable container cover 105, and the ribs 105 d are arranged at a plurality of intervals in the width direction (left and right direction). Although the number of ribs 105d on the front side and the rear side may be changed according to the number of transpiration boards 105b, in the present embodiment, since three transpiration boards 105b are used, the number of ribs 105d is also different. I'm thinking of three pieces each. The front ribs 105d extend rearward, the rear ribs 105d extend forward, and the transpiration board 105b is inserted between the ribs 105d. Thus, the rib 105d is a structure extending in the front-rear direction, and therefore, it is effective to restrain the movement of the transpiration board 105b due to the rubbing of vegetables. In addition, it is possible to reduce the space between the vegetable container cover 105 and the transpiration board 105 b as compared with the case where the transpiration board 105 b is fixed by a rib or the like extending in the vertical direction.

  FIG. 25 is a perspective view of the vegetable container cover 105 as viewed from below after the transpiration board 105 b is attached. A plurality of projections are formed on the back surface of the vegetable container cover 105, and the transpiration board 105 is attached by inserting a hole formed in the transpiration board 105b corresponding to the projections. As a result, the position of the transpiration board 105b is difficult to shift. Here, the projections of the vegetable container cover 105 have projections 105 j and 105 m which are symmetrical in the left-right direction with respect to the direction in which the door is pulled out, and projections 105 k which are in the asymmetrical shape. The protrusion 105k of the vegetable container cover 105 and the hole 105r having a symmetrical shape provided on the transpiration board 105b enable assembling to the vegetable container cover 105 without making a mistake in the back and forth of the transpiration board 105b.

  FIG. 26 is a perspective view when the vegetable container cover 105 is viewed from below after the supporting means for supporting the vegetable container cover 105 so as to prevent the transpiration board 105b from falling is attached. 29 is an enlarged view of a portion indicated by arrow E in FIG. 26, and FIG. 30 is a cross-sectional view taken along the line A-A in FIG. Each support means is fixed by sliding in the left-right direction with respect to the nail | claw part 105n formed in the front side, center, and back side of the back of the vegetable container cover 105. As shown in FIG. For this reason, it is difficult for the respective support means to be detached with respect to the movement of the vegetable container cover 105 in the front-rear direction. In addition, although each support means travels downward below the transpiration board 105b and is easily in contact with the vegetables, each support means has a shape extending in the front-rear direction, so the vegetable container cover 105 is compared with the shape extending in the left-right direction. It is hard to catch vegetables when opening and closing, and it can control that vegetables hurt and each support means falls off. In the present embodiment, four support means are provided, so four claw portions 105n of the vegetable container cover 105 are provided on the front side, the center, and the rear side respectively, but the number of the claw portions 105n and the support means If the number is the same, it is not limited to four.

  Further, the support means of the present embodiment is a first support means 105f attached to the left and right ends of the vegetable container cover 105, and a second support means attached to the overlapping portion between the two evaporation boards 105b. It has 105g. It is a case where the width dimension of the vegetable compartment 100 is large by making the transpiration board 105b into a plurality of sheets divided in the left-right direction instead of one and providing the second support means 105g in the adjacent transpiration board 105b. Even if the transpiration board 105b can be prevented from dropping. For this reason, the space between the vegetable container cover 105 and the transpiration board 105 b can be made small, and it is possible to absorb the condensation water generated in the vegetable container cover 105 efficiently. The second support means 105g also plays a role of enhancing the rigidity of the vegetable container cover 105. When one mesh-like support means is provided instead of providing a plurality of divided support means extending in the front-rear direction as in the present embodiment, the area of the support means is increased as a whole and is exposed in the vegetable room The range of the transpiration board 105b becomes narrow. Thus, when the area of the support means is increased, the water condensed on the support means is increased and the water tends to fall into the vegetable room.

  Furthermore, in the present embodiment, the bent portion is formed over the entire area in the width direction of the vegetable container cover 105 and each support means, and the rear side (rear side) is low. The strength of the vegetable container cover 105 is increased by the step of the bent portion. In the present embodiment, the first support means 105 f and the second support means 105 g have the same structure, but may have different structures.

  FIG. 27 is a diagram showing the positional relationship of the three transpiration boards 105b. As described above, in the present embodiment, since the transpiration board 105 b is formed by being divided into plural in the width direction, it can be applied in combination to refrigerators having different width dimensions, and the productivity is improved. Further, even in a vegetable room having a large width dimension, strain of the transpiration board 105b can be absorbed, and deflection can be suppressed.

  FIG. 28 is a cross-sectional view (in the vicinity of the left side) from the front of the upper container 102 and the vegetable container cover 105. The lateral end (the left end in FIG. 28) of the transpiration board 105 b is positioned outside the inner surface of the opening edge of the upper vessel 102. For this reason, the transpiration board 105b can be arrange | positioned over the substantially full width of a vegetable container, and not only a water absorption capability increases, but falling of the dew condensation water to the vegetable compartment can be suppressed. In addition, it is possible to prevent the side end of the transpiration board 105b from being caught when the upper container 102 is pulled out. Furthermore, the vertical projection of the first support means 105f and a part of the upper opening edge of the upper vessel 102 overlap, that is, on the sliding surface of the upper opening edge of the upper vessel 102, one of the first supporting means 105f. Since the part is located, breakage of the transpiration board 105b can also be prevented. In particular, since the upper container 102 and the vegetable container cover 105 are both made of polystyrene resin, abnormal noise and wear occur if they are rubbed directly when the upper container 102 is pulled out. However, in the present embodiment, since the first support means 105 f is made of polypropylene resin, such noise and the like are less likely to occur.

  FIG. 12 is a perspective view from the front side of the lower container 101. The inside of the lower container 101 is divided by the partition 103 into a front side and a back side. Then, a rear side lower space 101A is formed inside the back side of the lower vessel 101, and a front space 101B (not shown in FIG. 12) is formed inside the front side of the lower vessel 101. . A lower container cover 110 is attached to the back surface side of the lower container 101 so as to cover a surface to which dew condensation water adheres (condensed surface 101a, not shown in FIG. 12). The state of the generation of the condensed water will be described later with reference to FIG.

  FIG. 13 is a perspective view of the lower case 101 from the back side. As described above, the partitions 103 for dividing the inside of the lower container 101 are supported by the guide portions 104 provided on the left and right inner walls of the lower container 101 in a pair. Further, on the opposite surface (ie, the outer surface) of the lower container 101 to which the lower container cover 110 (see FIG. 12) is attached, a cold air supply surface 113 from the cold air supply adjusting means 141 (see FIG. 3) A transpiration cassette 112 is attached for transpiration the condensed water on the surface to which the above-mentioned dew condensation water adheres.

  FIG. 14 is a perspective view of a member attached to the side wall on the back side of the lower vessel 101, where (a) is the lower vessel cover 110 attached to the inner side, and (b) is the case 112 attached to the outer side is there. As shown in FIG. 14A, the lower container cover 110 is formed with a plurality of slits 110a. The direction of the formed slit 110 a is formed to be directed downward when flowing from the front side to the back side. Even if dew condensation water is generated on the surface of the lower container cover 110 by forming the slits 110 a in such a direction, the dew condensation water passes through the slits 110 a and is a transpiration board 112 e (described later) disposed on the back side. It is possible to prevent the dew condensation water from falling to the lower rear space 101A.

  Furthermore, the surface of the lower container cover 110 is subjected to embossing. That is, the surface of the lower container cover 110 is roughened. Thereby, the user can make it hard to notice presence of a water droplet by raising the hydrophilic property of the lower-part container cover 110 and making a water droplet hard to be made. Therefore, it is prevented that the user feels uneasy that the water drop may fall.

  Also, as shown in FIG. 14 (b), the transpiration cassette 112 is fitted with a case 112a that accommodates a cover 112c that is fitted to cover the transpiration board 112d (see FIG. 15) not shown in FIG. And a lower case 112b for fixing the cover 112c.

  FIG. 15 is an exploded perspective view of the transpiration cassette 112 attached to the outer back surface of the lower vessel 101, where (a) is a state where the transpiration board 112d is attached, and (b) is a state where the transpiration board 112d is removed. . The state shown in FIG. 15A also shows a state in which the cover 112c is pivoted to the front side and removed from the state shown in FIG. 14 to expose the transpiration board 112d. To explain this point, the lower end of the case 112 a and the lower end of the cover 112 c are rotatably engaged. Therefore, as shown in FIG. 15A, when the cover 112c is removed from the case 112a, the cover 112c pivots about the locked portion to move downward. Thereby, the plate-like transpiration board 112d is exposed to the front side.

  Further, a transpiration board 112e extending from the front side to the back side is connected to the lower end of the plate-like transpiration board 112d integrally with the transpiration board 112d. Therefore, the integral product consisting of the transpiration board 112d and the transpiration board 112e disposed inside the transpiration cassette 112 is an L-shaped one made of resin fibers.

  Since these transpiration boards 112 d and 112 e are made of the same material as the transpiration board 105 b described with reference to FIG. 10, the detailed description thereof is omitted. And although the details will be described later, water condensed on the inner side surface (the dew condensation surface 101a shown in FIG. 16) of the lower container 101 drops on the inner side surface and is absorbed by the transpiration board 112e. Then, the absorbed water diffuses the transpiration board 112 e and the transpiration board 112 d in this order to reach the transpiration board 112 d.

  As shown in FIG. 15 (b), on the back side of the transpiration board 112d, a protective material 112f having ventilating holes 112g through which air can pass is formed. Cold air flowing through the back side of the transpiration cassette 112 contacts the back side of the transpiration board 112 d through the vent holes 112 g. As a result, the water that has reached the transpiration board 112 d is transpirated in the cold air that has come into contact.

  FIG. 16 is a view showing a state when water in the rear lower stage space 101A is condensed to evaporate the condensed water to the outside of the vegetable room 100. As shown in FIG. Cold air from the cold air supply adjusting means 141 is blown on the cold air blowing surface 113 integrally formed on the rear side wall of the lower case 101. As a result, the wall temperature in the vicinity of the spray surface 113 is lower than the wall temperature of the other portions. Therefore, the moisture in the air in contact with the inner wall surface (condensed surface 101 a) of that portion, which constitutes the lower container 101, condenses to generate the condensed water 117. Condensed water 117 generated flows down from the gap portion 114 formed in the lower portion of the rear sidewall of the lower vessel 101 to the outside of the lower vessel 101 by its own weight and further to the transpiration board 112e through the slit 112c1 formed in the cover 112c. . The gap portion 114 may be formed at another place under the lower container 101, for example, may be formed on the bottom surface and the back side of the lower container 101.

  The moisture absorbed by the transpiration board 112e diffuses inside the transpiration board 112e, 112d. At this time, the absorbed moisture diffuses upward in the inside of the transpiration board 112 d disposed in the vertical direction. Then, the moisture diffused in the transpiration board 112 d is evaporated in the cold air contacting the transpiration board 112 d as described above, whereby the moisture of the air inside the vegetable compartment 100 is discharged to the outside of the vegetable compartment 100. As described above, the transpiration boards 112 e and 112 d suck the condensed water which has fallen down on the inner surface of the rear side wall from the gap portion 114 formed on the rear side wall to the outside of the lower vessel 101 and discharge it to the cold air. At this time, cold air is brought into direct contact with the rear side wall of the lower vessel 101, and the rear side wall itself is made a dew condensation surface, so that a simple structure without the metal high thermal conductivity member as in the prior art is provided. It is possible to control the humidity of the

  In the refrigerator 10 of the present embodiment, as shown in FIG. 16, the vertical length (height) of the transpiration board 112 d and the vertical length (height) of the spray surface 113 are substantially the same. There is. Here, the length in the left-right direction of the transpiration board 112 d and the length in the left-right direction of the spray surface 113 are substantially the same as shown in FIG. 13. Therefore, the area of the transpiration board 112 d is substantially the same as the area of the spray surface 113. Then, cold air is blown to the spray surface 113 which is the outer surface of the lower container 101, and the moisture in the storage is evaporated from the transpiration cassette 112 disposed in the lower part, thereby effectively utilizing the outer surface of the small lower container 101. , The humidity inside it can be controlled.

  Here, a modified example of the lower container cover 110 attached to the back side of the lower container 101 will be described.

  FIG. 17 is a view showing a modified example of the lower container cover 110 attached to the inside of the lower container 101, and is a perspective view of the transpiration unit cover 116 attached instead of the lower container cover 110. As shown in FIG. The lower container cover 110 shown in FIG. 14A has a plate shape, but instead of the lower container cover 110, an L-shaped transpiration unit cover 116 can be used.

  Similar to the slits 110 a in the lower container cover 110, the transpiration unit cover 116 is formed with a plurality of slits 116 a so as to generate a downward air flow. However, on the right side of the transpiration unit cover 116, an opposing member 116b opposed to the right side surface of the lower vessel 101 is formed. The surface of the transpiration unit cover 116 is embossed as in the case of the lower container cover 110 described above.

  FIG. 18 is a perspective view showing the inside of the lower vessel 101 from the front side when the evaporation unit cover 116 shown in FIG. 17 is attached to the inside of the lower vessel 101. The transpiration unit cover 116 is fixed to the inner wall of the lower vessel 101 by a screw or the like (not shown). As described above with reference to FIG. 16, in the refrigerator 10, dew condensation is intentionally generated by spraying cold air on the spray surface 113 (see FIG. 16) formed on the outer surface of the lower container 101. It has become.

  However, the spray surface 113 and the outer surface on the right side of the lower container 101 are close to each other. Therefore, when the lower vessel 101 is cooled by blowing cold air onto the spray surface 113, the cold heat is also transmitted to the right inner surface, and condensation water may also be generated on the right inner surface. Therefore, as shown in FIG. 18, in order to recover condensation water that may occur on the right inner surface, a transpiration unit cover 116 including an opposing member 116b is disposed on the back right side. The L-shaped transpiration unit cover 116 also has a dew condensation water receiving portion formed on the bottom surface, and the bottom surface is inclined to the back side. Therefore, even if condensation water generated on the right side surface reaches the bottom surface, it can be guided to the back side, and it is finally possible to absorb moisture and release it to cold air by the transpiration boards 112e and 112d. It is.

  On the right side surface of the transpiration unit cover 116, that is, below the opposing member 116b, there is formed a groove portion 116c having a slope which falls from the front side toward the back side. Then, when condensation water is generated on the surface of the opposing member 116b as a result of cooling the right side surface of the lower container 101, the condensation water dropped by its own weight is received by the groove 116c that inclines from the right wall to the rear wall. A drop into the interior of the container 101 is prevented. Then, the received condensed water flows through the groove portion 116c to reach the back side, passes through the condensed water discharge portion 116d provided close to the slit 116a, and is a transpiration board disposed on the back side of the transpiration unit cover 116 It is supplied to 112e. And the condensation water which arose on the surface of the opposing member 116b is also discharged | emitted by the exterior of the vegetable compartment 100 by doing in this way. That is, since the dew condensation water guide member extending from the right side wall adjacent to the back side wall to the back side wall is attached to the inner surface of the container, not only the dew condensation water condensed inside the back side wall but also dew condensation inside the right side wall The condensed water is also supplied to the inside of the rear side wall, and can be finally discharged to the outside of the rear side wall by the transpiration board 112e.

  In addition, although these are fixed with the screw etc. which are not shown in figure between the inner wall of the lower stage container 101, and the opposing surface of the opposing member 116b, some clearance gaps have arisen. However, since a layer of air is formed between them, the heat transfer performance is poor, and therefore, condensation water is less likely to occur. Therefore, the generation of dew condensation water between these gaps is sufficiently suppressed.

  Next, with reference to FIGS. 19 to 22, an operation of the lower container 101 or the like when the vegetable compartment door 6 of the refrigerator 10 is pulled out will be described. In addition, in FIGS. 19-22, illustration of a part of member mentioned above is abbreviate | omitted for the simplification of illustration.

  FIG. 19 is a cross-sectional view of the lower container 101 when the lower container 101 is completely accommodated in the vegetable compartment 100 of the refrigerator 10 main body. FIG. 19 shows a cross section as viewed from the left and right direction when the vicinity of the lock handle 106 is cut in the direction from the front side to the back side. As shown in FIG. 19, when the lower vessel 101 is accommodated in the refrigerator 10, the vegetable vessel cover 105 is the whole of the lower vessel 101 and the upper vessel 102 which are the openings of the lower vessel 101 (ie, the front space 101B). And the upper rear space 101C). Thereby, the airtightness inside these spaces is enhanced. Therefore, the carbon dioxide concentration inside can be maintained at 1000 ppm or more for all the spaces in the storage container 101, that is, not only for the lower rear space 101A but also for the front space 101B and the rear upper space 101C. Further, since the transpiration board 105b is positioned in the vertical projection of the rear upper stage space 101C, it is possible to control the humidity in the rear upper stage space 101C more effectively.

  At this time, a vegetable room is provided by a transpiration board 105b (see FIG. 10, not shown in FIG. 19) and a transpiration cassette 112 (see FIG. 6, not shown in FIG. 19) disposed on the lower surface of the vegetable container cover 105. The internal humidity of 100 is controlled. And each space which constitutes vegetable room 100, communication hole 106c, 106d, which was formed in communicating hole 102 (refer to Drawing 4, not shown in Drawing 19) and lock handle 106 which were formed in the bottom of upper row container 102 In communication by 106e (see FIG. 8, not shown in FIG. 19), the overall humidity of the vegetable compartment 100 is controlled.

  FIG. 20 is a cross-sectional view showing the lower container 101 when the lower container 101 is pulled out a little from the inside of the refrigerator 10, specifically when the space up to the front space 101B is pulled out of the vegetable compartment 100. When the lower container 101 is drawn to the front side, the upper container 102 is also drawn to the front side accordingly. However, the relative position of the upper container 102 in the lower container 101 does not change, and even if the lower container 101 is pulled out to the front side, the upper container 102 is supported and fixed above the rear lower space 101A. Yes.

  When the lower container 101 is pulled out to the front side, the vegetable container cover 105 slides on the upper end of the upper container 102 along with the pulling out operation, and the upper end 105 h of the vegetable container cover 105 contacts the front side surface of the lock handle 106 Do. Thereby, even if the lower container 101 is pulled out to the front side, only the front space 101B is opened to the outside (exposed from the vegetable container cover 105), and the opening of the rear upper space 101C is covered with the vegetable container cover 105. The airtightness of the upper rear space 101C is maintained. Therefore, it is possible to maintain the concentration of carbon dioxide generated from vegetables etc. higher in the rear upper stage space 101C than in the front space 101B. In addition, when the lower container 101 is pulled out to the front side, the moving amount of the vegetable container cover 105 is smaller than the moving amount of the upper container 102. Therefore, when the user wants to use only the front space 101B, the operation of the vegetable container cover 105 or the lock handle 106 is not required.

  When the lower container 101 is further pulled out to the front side from the state shown in FIG. 20, the lower container 101 is pulled out with the vegetable container cover 105 remaining inside the main body of the refrigerator 10. That is, when the rear upper stage space 101C is also drawn out of the vegetable compartment 100, not only the opening of the front side space 101B but also a partial opening of the rear upper stage space 101C is exposed from the vegetable container cover 105.

  FIG. 21 is a cross-sectional view showing a state in which the rear upper stage space 101C is released by releasing the lock handle 106 after completely pulling out the lower vessel 101 from the inside of the refrigerator 10. By operating the lock handle 106, the vegetable container cover 105 is moved so that the upper end 105h (not shown in FIG. 21) on the front side of the vegetable container cover 105 is above the upper end of the lock handle 106. Thereby, the rear upper stage space 101C is opened to the outside, and furthermore, the upper vessel 102 can be pulled out to the front side.

  FIG. 22 is a cross-sectional view of the refrigerator 10 when the lower container 101 and the upper container 102 are completely pulled out of the refrigerator 10. When the upper container 102 is completely pulled out, the lower end on the front side of the upper container 102 is placed on the upper end of the partition 103, which enables stable extraction of vegetables and the like. Further, when the upper container 102 is completely pulled out, the vegetable container cover 105 is disposed with a slight inclination from the back side to the front side. That is, the vegetable container cover 105 is disposed inside the refrigerator 10 such that the height in the vertical direction of the front end (the upper end 105d) is slightly higher than the rear end 105e. Thereby, a space (extraction port) opened to the outside of the upper container 102 can be widely secured, and it becomes easy to take out vegetables and the like.

  In this embodiment, since trimethylamine which is an alkaline gas is decomposed in a short time by the platinum catalyst 118, the neutralization of the surface of the acidified vegetable by the dissolution of carbon dioxide is suppressed, and the acidity of the surface is increased. It becomes possible. That is, when vegetables are stored in a storage container, while the pH of the surface conventionally increases, in the present embodiment, the pH of the surface decreases. As a result, enzymes and microorganisms generated on the surface of vegetables are suppressed, and the progress of rot is suppressed. Further, when trimethylamine is decomposed, carbon dioxide is also generated, so the effect of increasing carbon dioxide is also high as compared with the case of using a photocatalyst. The experiment was actually performed, and it was found that the use of the platinum catalyst 118 has about twice the ability to generate carbon dioxide as compared with the use of the photocatalyst. For this reason, it is possible to increase the internal carbon dioxide even in a wide area.

  FIG. 23 shows the remaining amount of vitamin C in vegetables in each space of the storage container with respect to the conventional structure intended to increase the freshness of only the vegetables in the lower rear space by using a photocatalyst and the structure of the present embodiment It is a figure which shows the result of the experiment which measured. FIG. 23 (a) is a comparison of the remaining amount of vitamin C after 7 days with half cut orange stored in the rear upper stage space 101C, and it is found that it is about 21% higher than the conventional one. The FIG. 23 (b) is a comparison of the amount of remaining vitamin C after 6 days with half-cut long onions stored in the front space 101B, and it was found that it is about 22% higher than before. . FIG. 23 (c) shows the remaining amount of vitamin C after 7 days of storing komatsuna in the lower rear space 101A, and it was found to be equivalent to that of the conventional case. That is, according to the present embodiment, not only in the lower rear space 101A but also in the upper rear space 101C and the front space 101B, the nutrient component in the vegetables is less likely to be consumed by the aging action, and the vegetables have nutritional value It is possible to keep it high for a long time.

  Although the present embodiment has been described above with reference to the drawings, the present invention is not limited to the above embodiment.

  For example, although the transpiration cassette 112 is disposed on the back side of the lower container 101, the transpiration board may be disposed along the inner surface on the back side of the lower container 101 instead of the transpiration cassette 112. In this case, the moisture storage and release member is disposed inside the lower rear space 101A. And at this time, it is preferable to provide the communicating hole which connects the inside and outside of the upper stage container 101 above this transpiration board. Thus, the water condensed on the inner surface of the lower vessel 101 above the transpiration board is absorbed by the transpiration board disposed below. Then, the absorbed water is appropriately evaporated by the air inside the lower vessel 101 (inside the rear lower space 101A), and is discharged to the outside of the lower vessel 101 through the communication hole formed at the position where it is easily discharged to the outside. It will be done.

  Also, for example, although the transpiration board 105b as a moisture storage and release member is disposed on the lower surface of the vegetable container cover 105, the moisture storage and release member is not this lower surface but the side surface (for example, the side surface on the back side) of the upper container 102 It may be.

  Furthermore, since the rear upper space 101C as the first space, the rear lower space 101A as the second space, and the front space 101B communicate with each other by the communication hole 106e formed in the lock handle 106, As long as the water storage and release member is disposed in at least one of the spaces, the humidity can be controlled for any space. Of course, the moisture storage and release member may be disposed in each of these two spaces. In the above-described embodiment, the transpiration board 105b is disposed inside the rear upper stage space 101C, and the water absorption and release member is not disposed inside the rear lower stage space 101A.

  Further, for example, the area of the transpiration board 112 d does not have to be substantially the same as the area of the spray surface 113 formed on the outer surface of the lower vessel 101, and the area of the spray surface 113 is more May be larger than the area of the transpiration board 112d. That is, the rear sidewall of the lower vessel 101 may be configured such that the area of the area exposed to the storage chamber is larger than the area of the area to which the transpiration board 112d is attached. At this time, the transpiration board 112 d is attached so as to be lower than the center of height of the rear side wall of the lower vessel 101. In addition, the amount of cold air sprayed onto the spray surface 113 may be appropriately changed according to the amount of vegetables stored in the vegetable room 100 or the like.

  Furthermore, although the blowing surface 113 was arrange | positioned on the right side, you may change suitably according to the position of the cold air | gas supply adjustment means 141, and may be center vicinity or the left side.

  In addition, the communication holes 105c formed in the vegetable container cover 105 do not have to be at equal intervals, and can be formed by changing intervals as necessary. However, the moisture in the inside of the vegetable compartment 100 can be discharged to the outside more efficiently by providing it in the vicinity of the passage of the cool air which flows outside the vegetable container cover 105.

  Furthermore, after the lower container 101 was pulled out to the front side, the support fixing of the upper container 102 was released by operating the lock handle 106, but without operating the lock handle 106, the upper container is pulled up with the lower container 101 pulled. The container 102 may also be opened to the outside.

  Although the refrigerator 10 is divided into three spaces of the lower rear space 101A, the front space 101B, and the rear upper space 101C, two spaces may be formed, and four or more spaces are formed. You may do so.

  In addition to these, it is possible to replace part of the configuration of one embodiment with the configuration of another embodiment, and it is also possible to add the configuration of another embodiment to the configuration of one embodiment. is there. Furthermore, other configurations can be added, deleted, replaced, etc., with respect to a part of the configurations of the respective embodiments.
