The refrigerator 10 shown in FIG. 1 is provided on the front surface of the refrigerator main body 1 with a refrigerating compartment left door 2, a refrigerating compartment right door 3, an ice making compartment door 4a, a rapid freezing compartment door 4b, a freezing compartment door 5, and a vegetable compartment door 6. The left door 2 of the refrigerating compartment can be rotated in the front direction of the paper by the upper hinge 7a and the lower hinge 8a. Further, the refrigerating chamber right door 3 can be rotated in the paper front direction by the upper hinge 7b and the lower hinge 8b. That is, the refrigerating compartment left door 2 and the refrigerating compartment right door 3 are arranged to be vertically movable, and a refrigerating compartment (not shown) is formed in the space formed by the refrigerator main body 1.

Further, the ice making compartment door 4a, the quick freezing compartment door 4b, and the freezing compartment door 5 can be pulled out in the forward direction of the paper. Next, an ice making compartment, a rapid freezing compartment, and a freezing compartment (none of which are shown) are formed in the space formed by the refrigerator main body 1. The vegetable room door 6 is also the same Pull the paper in the forward direction. Further, a vegetable compartment 100 (a storage compartment, see FIG. 2) is formed in a space formed by the refrigerator main body 1.

2 is a perspective view of the lower container 101 in which the upper container 102 has been mounted in the refrigerator 10. In the vegetable compartment 100, the inner box 124 of the refrigerator main body 1 (refer to FIG. 1) constitutes the wall surface (left wall, right wall, and bottom wall) of the vegetable compartment 100. Further, the vegetable container lid 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 airtightness of each of the lower container 101 and the upper container 102 is ensured to some extent.

In the vegetable compartment 100, the lower container 101 (storage container) and the upper container 102 (storage container, inner container) are freely housed on the front side and the back side (hereinafter sometimes referred to as "in the front-rear direction"). However, in the present embodiment, even if the lower stage container 101 moves in the front-rear direction, the position of the upper stage container 102 inside the lower stage container 101 does not change. However, the details will be described later. By the user operating the lock lever 106 (refer to FIG. 8), the upper container 102 can also be pulled out to the front side.

A machine room (not shown) for arranging a compressor (not shown) or the like outside the refrigerator is formed on the back side of the vegetable compartment 100. Therefore, the bottom wall is higher on the back side than the front side. Further, the lower container 101 is provided with a partition member 103 made of glass. Thereby, the lower stage container 101 is divided into two scribe areas (the front side space 101B on the front side, the rear side lower stage space 101A on the back side, and the rear side upper stage space 101C, which are not shown in FIG. 2). Next, the upper stage container 102 is disposed so as to cover the space on the back side of the two partitions of the lower stage container 101.

3 is a perspective view of the vegetable compartment 100 in which the vegetable container lid 105 (cover member) is disposed in the refrigerator 10. The vegetable container lid 105 is disposed so as to cover the upper portion of the lower container 101 and the upper container 102 (see FIG. 4, not shown in FIG. 3). Among these, the vegetable container lid 105 is disposed above the lower stage container 101 when the lower stage container 101 is housed in the refrigerator 10. Therefore, when the lower stage container 101 is completely pulled out from the refrigerator 10, the vegetable container cover 105 remains inside the refrigerator 10, and the inside of the lower stage container 101 is opened to the outside.

The vegetable container lid 105 is made of a resin having light transparency. A embossing (a plurality of grooves extending from the front side toward the back side) 105a is formed on the upper surface of the vegetable container lid 105 and on the front side. Next, when the user pulls the lower container 101 and the upper container 102 to the front side, and when the user uses the light, the light from the LED mounted on the outside of the vegetable compartment 100 is illuminated by the embossing 105a. The inside of the lower stage container 101 and the upper stage container 102. As described above, the embossing 105a is formed by a plurality of grooves, and thus the light system incident on the embossing 105a is diffused. Further, the embossing 105a is formed by a plurality of grooves, and therefore has a large surface area. Therefore, a large range is irradiated while suppressing the occurrence of the shadow.

Further, a vapor deposition plate 105b is disposed under the vegetable container lid 105 (that is, a surface facing the inside of the vegetable compartment 100). Further, a plurality of communication holes 105c (internal and external communication holes) that communicate the inside and the outside of the vegetable compartment 100 are formed on the upper surface of the vegetable container lid 105. The details of these are described later with reference to FIG. 9 or FIG.

In addition, in the wall of the vegetable room 100, or the vegetable room The heat insulating partition wall between the 100 and the freezing compartment is formed with a cool air blowing port (not shown). Next, a cooling air supply adjusting means 141 that can control the supply of the cold air that cools the vegetable compartment 100 is provided in the air outlet. As a result, the cold air blown into the vegetable compartment 100 enters the rear side space 101A (see FIG. 4) and leaks from the front side. Further, it is possible to prevent the humidity in the rear side space 101A from excessively rising and to prevent dew condensation at an unintended portion.

Figure 4 is a cross-sectional view taken along line A-A of Figure 3. Here, the vegetable compartment door 6 shown in Fig. 1 is also shown in Fig. 4. The lower stage container 101 is divided into three spaces such as a rear side lower section space 101A, a front side space 101B, and a rear side upper section space 101C. Among these, the rear lower stage space 101A is formed by partitioning the lower stage container 101 by the partition member 103 disposed inside the lower stage container 101 and the lower surface of the upper stage container 102. Further, the front side space 101B is formed by partitioning the lower stage container 101 by the side surface on the front side of the upper stage container 102, the partition member 103, and the vegetable container lid 105. The rear upper stage space 101C is formed by partitioning the lower stage container 101 by the upper stage container 102 and the vegetable container lid 105.

Among the above-mentioned spaces, three spaces for controlling the inside of the lower container 101 (that is, the rear lower space 101A, the front space 101B, and the rear upper space 101C) are disposed on the back side of the rear lower space 101A. The evapotranspiration of the humidity within the space 匣 112. The details of the evapotranspiration 112 will be described later with reference to FIG. 16 and the like.

Further, on the bottom surface of the upper stage container 102, a rear side lower section space 101A (first space) and a rear side upper section space 101C are formed. Two spaces) communicating holes 102a (space communicating holes) that communicate with each other. Thereby, dehumidification of both the rear side lower section space 101A and the rear side upper section space 101C can be performed.

Fig. 5 is a perspective view of the front side of the upper stage container 102. The lock handle 106 (supporting the fixing release mechanism) disposed on the front side of the upper stage container 102 is an upper stage container 102 that is supported by the inside of the lower stage container 101 in a normal state, and the upper stage container 102 can be operated by a user. Move in the front and rear direction. The lock lever 106 is configured to include a pressing portion 106a that is moved toward the front side of the upper container 102 by pressing, and a recess portion 106b that is formed by slightly recessing the upper end of the upper container 102. Then, the user presses the thumb or the like of the hand holding the pressing portion 106a while holding the depressed portion 106b, whereby the support of the upper container 102 in the lower container 101 is released. Then, the upper stage container 102 can be moved in the front-rear direction.

Further, the inside of the front side of the lock lever 106 is formed with the inside of the lock handle 106, and three spaces such as the rear lower space 101A, the front space 101B, and the rear upper space 101C (hereinafter sometimes referred to as the space) It is a communication hole 106c (space communication hole) which communicates with each other. Further, a platinum catalyst 118 is accommodated in a position where the inside of the lock lever 106 is in contact with the air in each space (see FIG. 8(b)). Therefore, the air taken into the lock cylinder 106 through the communication hole 106c contacts the platinum catalyst 118, and then the air that has come into contact with the platinum catalyst 118 is supplied to each space. Thereby, the air in the front side space 101B can reach the evaporation plate 105b in the rear upper space 101C (refer to FIG. 10). Or the condensation surface 101a formed on the back side in the back side lower space 101A (refer FIG. 16). Therefore, the control of the humidity of the air in the front side space 101B can be performed.

Fig. 6 is a perspective view of the back side of the upper stage container 102. A communication hole 106d that communicates with each other through the inside of the lock handle 106 is also formed below the back side of the lock lever 106. Then, similarly to the communication hole 106c, the air taken into the lock cylinder 106 through the communication hole 106d contacts the platinum catalyst 118, and then the air that has come into contact with the platinum catalyst 118 is supplied to each space. Among these, the communication hole 106d passes through the hole 102b formed on the front side surface of the upper stage container 102, and faces the rear upper stage space 101C.

Figure 7 is a perspective view of the lower side of the upper container 102. Below the lock handle 106, a communication hole 106e that communicates three spaces such as the rear lower space 101A, the front space 101B, and the rear upper space 101C is formed through the inside of the lock handle 106. Then, similarly to the communication holes 106c and 106d, the air taken into the lock cylinder 106 through the communication hole 106e contacts the platinum catalyst, and then the air that has come into contact with the platinum catalyst is supplied to each space. The communication hole 106e passes through the hole 102c formed in the bottom surface of the upper stage container 102 and faces the rear lower stage space 101A.

Fig. 8 is a cross-sectional view showing the components constituting the lock lever 106, (a) is a side view on the back side thereof, (b) is an exploded perspective view, and (c) is a cross-sectional view taken along line B-B in (a). Here, in FIG. 8(c), in order to simplify the illustration, the unlocking (supporting and fixing of the upper container 102) is omitted. An illustration of a part of the organization.

As shown in Fig. 8(a), the lock lever 106 is configured to include a catalyst cover 106f having a communication hole 106d, a handle housing 106g for mounting the catalyst cover 106f, and a handle housing 106g front handle housing front 106h; and handlebar 106j integrally formed with the pressing portion 106a (see Fig. 5). Next, as shown in FIG. 8(b), when the catalyst cover 106f is detached by the lock lever 106, the platinum catalyst 118 is disposed to extend in the left-right direction inside the lock handle 106. The platinum catalyst 118 is disposed inside the lock handle 106 so as to avoid a mechanism (not shown) for releasing the lock in the lock handle 106.

In Fig. 8(c), the thick arrow indicates the air flow direction. As shown in FIG. 8(c), the platinum catalyst 118 is in contact with the air in each space through the communication holes 106c, 106d, and 106e. Further, the illustration by the arrow is not performed, but the air in each space is not supplied to the platinum catalyst 118 and is supplied to other spaces.

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 when there is no light such as an LED. Ethylene is decomposed by the platinum catalyst 118, whereby carbon dioxide and water vapor are generated. Then, the generated carbon dioxide is supplied to each space through the communication hole, so that the pores of the vegetables stored in the respective spaces are closed, the vegetable respiration is suppressed, and the reduction of nutrients due to respiration or drying is suppressed. Therefore, the freshness of the vegetables is maintained for a long time. In the installation place of the platinum catalyst 118, the catalyst storage portion is provided on at least one wall surface partitioning each space, and the catalyst is received in the catalyst. The nano-portion accommodates the platinum catalyst 118, and is not limited to the inside of the lock handle 106. At this time, a communication hole that communicates with each space is also formed in the catalyst containing portion. Further, a configuration may be adopted in which a catalyst accommodating portion is provided on any wall surface of each space, and a communication hole is formed in a wall surface that partitions each space.

In addition, when carbon dioxide is dissolved in water existing on the surface of vegetables or the like stored in the vegetable compartment 100, the surface of vegetables or the like becomes acidic. However, if trimethylamine which exhibits alkalinity occurs when dissolved in water, trimethylamine also dissolves in the water present on the surface of the vegetable, and thus the surface of the vegetable which is acidified by the dissolution of carbon dioxide is neutralized. However, in the refrigerator 10, trimethylamine is decomposed by the platinum catalyst 118, whereby the surface of the vegetables or the like stored in the vegetable compartment 100 is 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 a pellet and is housed in the lock handle 106 in a state of being housed in the bag. Thereby, the pellet-shaped platinum catalyst 118 is moderately mixed in the bag when the upper container 102 is pulled out and stored. Therefore, the air is prevented from being contacted by only one direction with respect to the pellet, and the catalyst function is maintained. Among them, other migration metal catalysts may be used instead of being limited to the platinum catalyst 118. In the case of the migration metal catalyst, ruthenium dioxide (intermediate pore ruthenium dioxide) having pores is used in the refrigerator 10, and fine particles of a migration metal such as platinum or ruthenium are supported inside the pores.

Fig. 9 is a perspective view from above of the vegetable container lid 105. As described above, the embossing 105a is formed on the upper surface side of the vegetable container lid 105. Light from the LED illumination (not shown) is irradiated inside the vegetable compartment 100 from the outside of the embossing 105a. Also, in vegetables The container lid body 105 is formed with a plurality of inside and outside of the rear side upper space 101C which is formed between the upper stage container 102 (not shown in FIG. 9) disposed below the vegetable container lid 105 and the vegetable container lid 105. Connected communication holes 105c. The communication hole 105c is formed in the refrigerator 10, and is formed in the vicinity of the cold air return port (not shown) formed in the right side of the back surface of the vegetable compartment 100.

Fig. 10 is a perspective view of the lower side of the vegetable container lid 105, (a) is a whole view, and (b) is a view showing a portion C of (a) in an enlarged manner. Fig. 10 (a) shows a state in which the vegetable container lid 105 is viewed from the lower side of the front side of the vegetable container lid 105. As shown in Fig. 10 (a), a vapor deposition plate 105b (water absorbing and discharging member) is disposed on the lower surface of the vegetable container lid 105 (the surface facing the inside of the upper container 102). The vapor deposition plate 105b is a flat member formed by knitting resin fibers such as PET fibers, and passes through the air, and the liquid moisture is absorbed. Then, the moisture absorbed by the moisture can evade (release) the air.

As shown in FIG. 10(b), on the lower surface of the vegetable container lid 105, ribs 105d are formed to face the communication holes 105c that communicate the inside and the outside of the vegetable compartment 100. Next, the evaporation plate 105b is inserted into the space 105e formed between the communication hole 105c and the rib 105d, whereby the evaporation plate 105b is held under the vegetable container cover 105. Further, by holding the evaporation plate 105b in the space 105e, the communication hole 105c is positioned under the vertical projection of the vapor deposition plate 105b, and the communication hole 105c is closed by the vapor deposition plate 105b. By this, the air containing the moisture inside the lower stage container 101 and the upper stage container 102 is discharged to the outside of the vegetable compartment 100 through the communication hole 105c, and the cold is suppressed. The gas directly enters the inside of the vegetable compartment 100 through the communication hole 105c directly from the outside of the vegetable compartment 100.

Further, when the air inside the rear upper space 105C contacts the vegetable container lid 105, the moisture contained in the air may be dew condensation in the vegetable container lid 105 to cause dew condensation. However, the dew condensation water generated is absorbed by the vapor deposition plate 105b disposed over the entire upper portion of the upper container 102. Therefore, the dew condensation water is suppressed from falling to the rear upper space 10C.

Figure 11 is a side view of the vegetable container lid 105. In FIG. 11, the lower stage container 101 and the lower stage container 102 which are disposed below the vegetable container lid 105 are indicated by imaginary lines. The slick plate 105b is attached to the lower surface of the vegetable container lid 105 facing the inside of the upper container 102. Moreover, although not shown in FIG. 11, the cold air for cooling the vegetable compartment 100 is flow-flowed above the vegetable container cover 105. Therefore, the through-flow cold air flows through the evaporation plate 105b exposed by the communication hole 105c. Thereby, the water of the liquid which is absorbed by the evaporation plate 105b is formed into water vapor and is released to the cold air flowing therethrough. That is, the moisture in the vegetable compartment 100 is absorbed in the evaporation plate 105b, and the moisture-absorbing moisture is discharged to the outside of the vegetable through the communication hole 105c. Therefore, the evaporation plate 105b is prevented from excessively absorbing water, and the water droplets are dropped to the inside of the upper container 102.

Fig. 12 is a perspective view of the front side of the lower stage container 101. The inside of the lower stage container 101 is partitioned into a front side and a back side by the partition member 103. Next, a rear lower stage space 101A is formed inside the back side of the lower stage container 101, and further, on the front side of the lower stage container 101. The inside is formed with a front side space 101B (not shown in FIG. 12). The lower container lid body 110 is attached to the back surface side of the lower stage container 101 so as to cover the surface (dew condensation surface 101a, not shown in FIG. 12) to which the dew condensation water adheres. The appearance of dew condensation water will be described later with reference to Fig. 16 .

Fig. 13 is a perspective view of the back side of the lower stage container 101. The partition 103 partitioning the inside of the lower stage container 101 as described above is supported by a pair of guide portions 104 provided on the left and right inner walls of the lower stage container 101. In addition, the surface of the lower side of the lower container 101 to which the lower container lid 110 (see FIG. 12) is attached (that is, the outer surface) is attached with cold air from the cold air supply adjusting means 141 (see FIG. 3). The surface 113 and the water dewed on the surface to which the dew condensation water adheres are evaporated to the enthalpy enthalpy 112 of the cold air.

Fig. 14 is a perspective view of a member attached to a side wall on the back side of the lower stage container 101, wherein (a) is a lower container lid body 110 mounted on the inner side surface, and (b) is a housing 112 attached to the outer side surface. As shown in Fig. 14 (a), a plurality of slits 110a are formed in the lower container lid 110. The direction of the slit 110a formed is formed to face the downward direction when flowing from the front side to the back side. Even in the case where the slit 110a is formed in the direction as described above, in the case where dew condensation water is generated on the surface of the lower container lid 110, the dew condensation water can be reached through the slit 110a to the vapor deposition plate disposed on the back side thereof. 112e (described later) prevents the dew condensation water from falling to the rear lower space 101A.

Further, the surface of the lower container lid 110 is subjected to roughening processing. That is, the surface of the lower container lid 110 is roughened. Chemical. Thereby, the hydrophilicity of the lower container lid 110 is increased, and it is difficult to form water droplets, whereby the user can hardly perceive the presence of water droplets. Therefore, the user is prevented from feeling uneasy about the drop of water droplets.

In addition, as shown in FIG. 14(b), the evapotranspiration 112 is configured to include a casing 112a that accommodates a lid body 112c that is fitted to cover the slick plate 112d (see FIG. 15) (not shown) in FIG. And fixing the lower casing 112b of the cover body 112c to be embedded.

Fig. 15 is an exploded perspective view of the evapotranspiration 112 attached to the outer back surface of the lower stage container 101, wherein (a) the state in which the slick plate 112d is attached, and (b) the state in which the slick plate 112d is removed. In the state shown in Fig. 15 (a), the lid body 112c is slid to the front side and is detached, and the squirt plate 112d is exposed. In this case, the lower end portion of the casing 112a and the lower end portion of the lid body 112c are rotatably fastened. Therefore, as shown in Fig. 15 (a), when the lid body 112c is removed by the casing 112a, the portion to be buckled is used as the shaft center, and the lid body 112c is rotated and moved downward. Thereby, the plate-shaped evaporation plate 112d is exposed toward the front side.

Further, a vapor deposition plate 112e extending from the front side toward the back side is integrally connected to the vapor deposition plate 112d at the lower end of the plate-shaped vapor deposition plate 112d. Therefore, one of the vapor deposition plates 112d and the evaporation plate 112e disposed inside the evaporating bowl 112 is formed of an L shape of resin fibers.

The evaporation plates 112d and 112e are the same as those of the evaporation plate 105b described with reference to Fig. 10, and therefore the detailed description thereof is omitted. Description. Next, as will be described later in detail, water dewed on the inner side surface (dew condensation surface 101a shown in FIG. 16) of the lower stage container 101 is dripped on the inner side surface and is absorbed by the vapor deposition plate 112e. Next, the moisture-absorbing water system is sequentially diffused on the evaporation plate 112e and the evaporation plate 112d to the evaporation plate 112d.

As shown in Fig. 15 (b), a protective material 112f in which a vent hole 112g through which air can pass is formed is disposed on the back side of the vapor deposition plate 112d. The cold air flowing through the back side of the steam enthalpy 112 passes through the vent hole 112g to come into contact with the back side of the vapor deposition plate 112d. Thereby, the moisture to the evaporation plate 112d is evaporated to the cold air which is in contact.

FIG. 16 is a view showing a state in which moisture in the inside of the rear lower stage space 101A is dew condensation, and the dew condensation water is evaporated to the outside of the vegetable compartment 100. The cold air blowing surface 113 integrally formed on the rear side wall of the lower stage container 101 is blown with cold air from the cold air supply adjusting means 141. Thereby, the wall temperature of the near side of the blowing surface 113 is lower than the wall temperature of the other parts. Therefore, the dew condensation water 117 is generated by condensation of moisture in the air that comes into contact with the inner wall surface (dew condensation surface 101a) of the portion constituting the lower stage container 101. The dew condensation water 117 that has occurred is dropped by the gap portion 114 formed at the lower portion of the rear side wall of the lower stage container 101 to the outside of the lower stage container 101 due to its own weight, and flows to the evaporation plate 112e through the slit 112c1 formed in the lid body 112c. . The gap portion 114 may be formed in another place on the lower portion of the lower stage container 101, or may be formed on the bottom surface and the back side of the lower stage container 101, for example.

The moisture absorbed by the evaporation plate 112e is diffused inside the evaporation plates 112e and 112d. At this time, the moisture absorbed is below the above The inside of the arranged evaporation plate 112d is diffused upward. Then, the moisture diffused in the evaporation plate 112d is evaporated to the cold air contacting the evaporation plate 112d 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 evaporation plates 112e and 112d cause the dew condensation water flowing down on the inner surface of the rear side wall to be sucked out of the lower portion of the container 101 by the gap portion 114 formed on the rear side wall, and is discharged to the cold air. At this time, the cold air is directly brought into contact with the rear side wall of the lower stage container 101, and the rear side wall itself is formed into a dew condensation surface, whereby the metal high heat conduction member can be provided without a conventional structure, and the humidity inside the storage chamber can be controlled simply.

In the refrigerator 10 of the present embodiment, as shown in FIG. 16, the length (height) of the vertical direction of the vapor deposition plate 112d and the length (height) of the vertical direction of the blowing surface 113 are substantially the same. Here, the length of the vapor deposition plate 112d in the left-right direction and the length of the blowing surface 113 in the left-right direction are substantially the same as shown in FIG. Therefore, the area of the vapor deposition plate 112d is formed to be substantially the same as the area of the blowing surface 113. Next, cold air is blown to the outer surface of the lower stage container 101, that is, the blowing surface 113, and the enthalpy 112 placed in the lower portion of the lower stage container 101 evaporates the moisture in the refrigerator, whereby the smaller lower container 101 can be effectively utilized. The outer side controls the humidity inside.

Here, a modification of the lower container lid 110 attached to the back side of the lower stage container 101 will be described.

Fig. 17 is a view showing a modification of the lower container lid body 110 attached to the inside of the lower stage container 101, and a perspective view of the ET unit cover 116 to which the lower container lid body 110 is attached is replaced. Figure 14 (a) The lower container lid 110 has a plate shape, but an L-shaped evapotranspiration unit cover 116 may be used instead of the lower container lid 110.

In the evapotranspiration unit cover 116, a plurality of slits 116a that generate a downward flow of air are formed in the same manner as the slits 110a in the lower container lid 110. However, on the right side of the ET unit cover 116, an opposing member 116b that faces the right side surface of the lower stage container 101 is formed. The surface of the evapotranspiration unit cover 116 is roughened in the same manner as the lower container lid body 110 described above.

Fig. 18 is a perspective view showing the inside of the lower stage container 101 when the evapotranspiration unit cover 116 shown in Fig. 17 is attached to the inside of the lower stage container 101 from the front side. The evapotranspiration unit cover 116 is fixed to the inner wall of the lower stage container 101 by a screw or the like (not shown). As described above with reference to Fig. 16, the refrigerator 10 is intended to generate dew condensation water by blowing cold air to the blowing surface 113 (see Fig. 16) formed on the outer surface of the lower stage container 101.

However, the blowing surface 113 is in close contact with the outer side surface of the right side of the lower container 101. Therefore, when the cold air is blown to the blowing surface 113, the lower stage container 101 is cooled, and the cold heat is also transmitted to the inner side surface on the right side, and dew condensation water is also generated on the inner side surface of the right side. Therefore, as shown in FIG. 18, in order to collect the dew condensation water which may generate|occur|produce on the inner side surface of the right side, the evaluation unit cover 116 which has the opposing member 116b is arrange|positioned on the right side of the back side. Further, the L-shaped ET unit cover 116 is formed with a dew condensation water receiving portion on the bottom surface, and has a slope in which the bottom surface thereof is lowered toward the back side. Therefore, even if the dew condensation water that occurs on the right side is assumed to arrive The bottom surface can also be guided to the back side, and finally the cold air is released by the evaporation plates 112e and 112d absorbing moisture.

On the right side surface of the ET unit cover 116, that is, below the opposing member 116b, a groove portion 116c having an inclination which is lowered from the front side toward the back side is formed. Next, as a result of the cooling of the right side surface of the lower stage container 101, if dew condensation water is generated on the surface of the opposing member 116b, the dew condensation water falling by its own weight is blocked by the groove portion 116c which is inclined toward the rear side wall by the right side wall. It is prevented from falling to the inside of the lower stage container 101. Then, the blocked dew condensation water flows through the groove portion 116c to the back side, and the dew condensation water discharge portion 116d provided by the slit 116a is supplied to the vapor deposition plate disposed on the back side of the ET unit cover 116. 112e. Next, by the above, the dew condensation water generated on the surface of the opposing member 116b is also discharged to the outside of the vegetable compartment 100. That is, the dew condensation water guiding member extending from the right side wall adjoining the rear side wall toward the rear side wall is attached to the inner surface of the container, and therefore, dew condensation water not only on the inner side of the rear side wall, but also condensation on the inner side of the right side wall Water is also supplied to the inside of the rear side wall, and is finally discharged to the outside of the rear side wall by the evaporation plate 112e.

However, although the inner wall of the lower stage container 101 and the opposing surface of the opposing member 116b are fixed by the screw etc. which are not shown, it has a slight gap. However, between these, since the air layer is formed, the heat transfer performance is poor, so that dew condensation water is less likely to be generated. Therefore, the occurrence of dew condensation water between the gaps is sufficiently suppressed.

Next, the operation of the lower stage container 101 and the like when the vegetable compartment door 6 of the refrigerator 10 is pulled out will be described with reference to Figs. 19 to 22 . its In FIGS. 19 to 22, a part of the members described above is omitted for simplification of illustration.

Fig. 19 is a cross-sectional view of the lower stage container 101 when the lower stage container 101 is completely housed in the vegetable compartment 100 of the main body of the refrigerator 10. Fig. 19 is a cross-sectional view when viewed from the left-right direction when the proximal side of the lock lever 106 is cut from the front side toward the rear side. As shown in FIG. 19, when the lower container 101 is accommodated in the refrigerator 10, the vegetable container lid 105 covers the entire lower container 101 and the upper container 102, which are the openings of the lower container 101 (that is, the front side space 101B and the upper side upper side). Space 101C). Thereby, the airtightness of the interior of the spaces is improved. Therefore, all the spaces in the storage container 101, that is, not only the rear lower space 101A, but also the front side space 101B and the rear side upper space 101C, can maintain the internal carbon dioxide concentration at 1000 ppm or more. Further, since the swash plate 105b is configured to be positioned in the vertical projection of the rear upper space 101C, the humidity in the rear upper space 101C can be more effectively controlled.

Further, at this time, the evaporation plate 105b (not shown in FIG. 10, FIG. 19) and the evapotranspiration 112 are disposed on the lower surface of the vegetable container lid 105 (see FIG. 6, which is not shown in FIG. The humidity inside the vegetable compartment 100 is controlled. Next, each space constituting the vegetable compartment 100 is formed by a communication hole 102 (not shown in FIG. 4, FIG. 19) formed on the bottom surface of the upper container 102 or a communication hole 106c, 106d, 106e formed in the lock handle 106. (see FIG. 8 and not shown in FIG. 19) and communicated with each other, thereby controlling the humidity of the entire vegetable compartment 100.

Figure 20 is a view showing that the lower container is slightly pulled out from the inside of the refrigerator 10. At 101 o'clock, specifically, a cross-sectional view of the lower container 101 when the front side space 101B is also pulled out of the vegetable compartment 100. If the lower stage container 101 is pulled out to the front side, the upper stage container 102 is also pulled out to the front side. However, the relative position of the upper stage container 102 inside the lower stage container 101 is not changed, and even if the lower stage container 101 is pulled out to the front side, the upper stage container 102 is kept supported to be fixed above the rear side lower section space 101A.

Further, when the lower container 101 is pulled out to the front side, the vegetable container lid 105 slides on the upper end of the upper container 102 in accordance with the pulling operation, and the upper end portion 105d of the vegetable container lid 105 contacts the front side of the lock handle 106. side. Thereby, even if the lower stage container 101 is pulled out to the front side, only the front side space 101B is opened to the outside (exposed by the vegetable container cover 105), and the opening of the rear side upper stage space 101C is covered with the vegetable container cover 105. Therefore, the airtightness of the rear upper space 101C is maintained. Therefore, the concentration of carbon dioxide generated by vegetables or the like can be maintained higher in the rear upper space 101C than in the front side space 101B. Further, when the lower stage container 101 is pulled out to the front side, the amount of movement of the vegetable container lid 105 is smaller than the amount of movement of the upper stage container 102. Therefore, if the user wants to use only the front side space 101B, the operation of the vegetable container lid 105 or the lock handle 106 is not required.

When the lower container 101 is further pulled out to the front side by the state shown in FIG. 20, the vegetable container lid 105 remains in the inside of the main body of the refrigerator 10, and the lower container 101 is pulled out. That is, when the rear upper space 101C is also pulled out of the vegetable compartment 100, not only the front space The opening of 101B, a part of the opening of the rear upper space 101C is exposed by the vegetable container cover 105.

Fig. 21 is a cross-sectional view showing a state in which the rear upper space 101C is released by releasing the lock handle 106 after the lower container 101 is completely pulled out from the refrigerator 10. By operating the lock lever 106, the upper end portion 105d (not shown in FIG. 21) on the front side of the vegetable container lid 105 is moved upward from the upper end of the lock handle 106, and the vegetable container lid 105 is moved. . Thereby, the rear upper space 101C is opened to the outside, and even the upper container 102 can be pulled toward the front side.

22 is a cross-sectional view of the refrigerator 10 when the lower stage container 101 and the upper stage container 102 are completely pulled out from the inside of the refrigerator 10. When the upper stage container 102 is completely pulled out, the lower end of the front side of the upper stage container 102 is placed on the upper end of the partition member 103, whereby vegetables and the like can be taken out stably. Further, when the upper container 102 is completely pulled out, the vegetable container lid 105 is disposed from the back side toward the front side with a slight inclination. In other words, the vegetable container lid 105 is disposed inside the refrigerator 10 such that the height of the upper end portion (the upper end portion 105d) in the vertical direction is slightly higher than the rear end portion 105e. Thereby, it is possible to broaden the space (taken out) that is opened to the outside of the upper container 102, and to easily take out vegetables and the like.

In the present embodiment, since the trimethylamine which is an alkaline gas is decomposed by the platinum catalyst 118 for a short period of time, the surface of the vegetable acidified by the dissolution of carbon dioxide is suppressed, and the acidity of the surface can be improved. In other words, when the vegetables are stored in the storage container, the pH of the surface is increased in the related art, whereas in the present embodiment, the pH of the surface is reduced. As a result, enzymes or microorganisms occurring on the surface of vegetables are inhibited, and spoilage progress is suppressed. Further, if trimethylamine is decomposed, carbon dioxide is also generated, so that the effect of increasing carbon dioxide is higher than in the case of using a photocatalyst. Through actual experiments, it was found that if the platinum catalyst 118 is used, there is about twice the carbon dioxide generating ability when using a photocatalyst. Therefore, even in a large area, the internal carbon dioxide can be increased.

FIG. 23 is a view showing a conventional structure for improving the freshness of vegetables having only the rear lower space, and a structure of the present embodiment, in which the photocatalyst is intended to be used, and measuring the amount of vitamin C remaining in the vegetables in each space of the storage container. A diagram of the experimental results. Fig. 23 (a) compares the citrus cut into 1/2 in the rear upper space 101C, and the amount of vitamin C remaining after 7 days is found to be about 21% higher than the conventional one. Fig. 23(b) compares the amount of vitamin C which has been cut into 1/2 in the front side space 101B and the amount of vitamin C remaining after 6 days, which is about 22% higher than the conventional one. Fig. 23(c) shows that the Komatsu is stored in the rear lower space 101A, and the amount of vitamin C remaining after 7 days is known to be equivalent to the conventional one. In other words, in the present embodiment, not only the rear lower space 101A but also the rear upper space 101C and the front space 101B, the nutrients in the vegetables are hardly consumed by the aging action, and can be stored for a long time with high nutritional value. vegetables.

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

For example, the evapotranspiration 112 is disposed on the back side of the lower stage container 101, but the squirting plate may be disposed along the inner side surface of the lower side of the lower stage container 101 instead of the evapotranspiration 112. At this time, the moisture absorption and release structure The pieces are disposed inside the rear side lower section space 101A. Next, at this time, it is preferable to provide a communication hole that connects the inner and outer phases of the upper stage container 101 above the evaporation plate. Thereby, the water condensed on the inner side surface of the lower stage container 101 above the transpiration plate is absorbed by the transpiration plate disposed below it. Then, the moisture-absorbed water is appropriately evaded by the air inside the lower stage container 101 (inside the rear lower stage space 101A), and is discharged to the lower stage container 101 through a communication hole formed at a position that is easily discharged to the outside. The outside.

Further, for example, the evaporation plate 105b as the moisture storage and discharge member is disposed on the lower surface of the vegetable container lid 105, but the moisture storage and discharge member may be the side surface of the upper container 102 (for example, the side on the back side), instead of For that below.

Further, the rear side upper space 101C as the first space, the rear lower space 101A as the second space, and the front side space 101B are connected by the communication hole 106e formed in the lock lever 106, and therefore, in the space At least one of them is provided with a moisture absorbing and discharging member, and humidity control can be performed for any space. Of course, a moisture absorbing and discharging member may be disposed in each of the two spaces. In the above embodiment, the vapor deposition plate 105b is disposed inside the rear upper space 101C, and the moisture storage and discharge member is not disposed inside the rear lower space 101A.

Further, for example, the area of the evaporation plate 112d does not need to be substantially the same as the area of the blowing surface 113 formed on the outer surface of the lower stage container 101, and the blowing surface 113 may be made from the viewpoint of more reliable condensation. The area is larger than the area of the evaporation plate 112d. That is, it can also be stored The area of the area in which the compartment is exposed is larger than the area of the area in which the evaporation plate 112d is mounted, and constitutes the rear side wall of the lower stage container 101. At this time, the slick plate 112d is attached so as to be positioned lower than the height center of the rear side wall of the lower stage container 101. Further, the amount of cold air blown onto the blowing surface 113 may be appropriately changed depending on the amount of vegetables stored in the vegetable compartment 100 or the like.

Further, the blowing surface 113 is disposed on the right side, but may be appropriately changed depending on the position of the cooling air supply adjusting means 141, or may be a center near side or a left side.

Further, the communication holes 105c formed in the vegetable container lid 105 do not need to be equally spaced, and may be formed by appropriately changing the interval as needed. However, by providing a cold air passage near the outside of the vegetable container lid 105, the moisture inside the vegetable compartment 100 can be discharged to the outside more efficiently.

In addition, after the lower container 101 is pulled out to the front side, the support of the upper container 102 is released by operating the lock handle 106, but the lock handle 106 is not required to be operated, and the upper container 102 is also pulled out with the lower container 101 being pulled out. Being opened to the outside.

The refrigerator 10 is divided into three spaces such as the rear lower space 101A, the front space 101B, and the rear upper space 101C. However, two spaces may be formed, and four or more spaces may be formed.

In addition to these, a part of the configuration of a certain embodiment may be replaced with a configuration of another embodiment, and a configuration of another embodiment may be added to the configuration of a certain embodiment. In addition, regarding each implementation A part of the configuration of the form may be added, deleted, replaced, or the like in other configurations.
