Description

[Technical Field]

[0001] An embodiment of the present invention relates to a refrigerator. [Background technology]

[0002] BACKGROUND ART Conventionally, some refrigerators have storage cases for vegetables and the like that are designed to maintain the freshness of foods such as vegetables or to prevent the growth of bacteria and mold. For example, in Patent Document 1, the lid of the storage case is a double lid with a hollow interior, and air vents are provided on the top and bottom surfaces of the double lid to create an air passage connecting to the outside, with a humidity-regulating member provided within the air passage. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2012-255609 Summary of the Invention [Problem to be solved by the invention]

[0004] However, even if the storage case with the above configuration is intended to maintain the freshness of vegetables and other items in a high-humidity environment, the humidity control member is positioned in a way that blocks the air passage inside the lid, making condensation more likely to occur. Furthermore, the humidity control member in the air passage inside the lid has a limited contact area with the air, which means that it is inevitably relatively small, and this may weaken its humidity control ability. Furthermore, there are many types of bacteria that can grow even in the refrigerator or vegetable compartment temperature ranges, and since the higher the humidity, the faster the bacteria grow, and bacteria (and their decomposition products) are also the cause of odors, it is important to ensure humidity control functions.

[0005] Therefore, a refrigerator is provided that can adequately agitate the air inside a container capable of storing food while ensuring a contact area between the air inside the container and a humidity adjusting member. [Means for solving the problem]

[0006] A refrigerator according to an embodiment includes a heat-insulating box having a storage compartment, and a container provided in the storage compartment having a storage space capable of holding food therein. The container includes an opening that opens the storage space into the storage compartment, a lid that covers the opening, and a humidity adjusting member that adjusts the humidity in the storage space. The humidity adjusting member is provided by the lid so as to be exposed to the air in the storage space, and at least one ventilation portion is provided around the humidity adjusting member.

[0008] Hereinafter, refrigerators according to a plurality of embodiments will be described with reference to the drawings. Note that substantially the same components in the respective embodiments will be denoted by the same reference numerals, and the description thereof will be omitted.

[0009] First Embodiment A refrigerator 1 shown in FIG. 1 is mainly composed of a heat-insulating box body 2 that is a vertically long rectangular box with an open front. The insulating box 2 is a refrigerator main body having multiple storage compartments therein, and will be referred to below as the "insulating box 2." In the following description, the open side of the insulating box 2 is the front side, and the left-right direction when viewed from the front side of the insulating box 2 is the left-right direction of the refrigerator 1 (see the "left-right" arrow directions in FIG. 1).

[0010] As shown in FIGS. 1 and 2, the heat-insulating box 2 has a structure in which a heat-insulating material 2c such as urethane foam is disposed in the space between an outer box 2a made of steel plate and an inner box 2b made of synthetic resin. The refrigerator 1 has multiple storage compartments, for example, a refrigerator compartment 11 and a vegetable compartment 12 arranged in order from the top inside the insulated box body 2, and below these an ice-making compartment 13 and a small freezer compartment 14 arranged side by side, and below these a freezer compartment 15 is arranged.

[0011] Both the refrigerator compartment 11 and the vegetable compartment 12 are in the refrigeration temperature range, for example, the refrigerator compartment 11 is a storage compartment in the plus temperature range of 1 to 5°C, and the vegetable compartment 12 is a storage compartment in the plus temperature range of 3 to 7°C, and they are separated into upper and lower sections by a partition wall 3 made of synthetic resin. 1 and 2, hinged double-door insulated doors 11a and 11b are provided at the front opening of the refrigerator compartment 11, and a drawer-type insulated door 12a is provided at the front opening of the vegetable compartment 12. A vegetable container 5 (described later) is connected to the back of this insulated door 12a.

[0012] A chilled compartment 16 is provided at the bottom (above the partition wall 3) of the refrigerator compartment 11 shown in Fig. 2. A chilled case 16a is provided so that it can be put in and taken out within the chilled compartment 16. Note that the above-mentioned chilled temperature range may also include a chilled temperature range of, for example, 0°C to 2°C, and is sometimes referred to as the normal temperature range of the refrigerator compartment 11.

[0013] The ice making compartment 13, small freezing compartment 14, and freezing compartment 15 are all storage compartments in the freezing temperature range (for example, below -15°C, preferably below -18°C), and the vegetable compartment 12, ice making compartment 13, and small freezing compartment 14 are separated vertically by an insulating partition wall 4. The front opening of ice making compartment 13 is provided with drawer-type insulated door 13a as shown in Fig. 1, and an ice storage container (not shown) is connected to the back of insulated door 13a. Also, as shown in Fig. 2, the front opening of small freezing compartment 14 is provided with drawer-type insulated door 14a to which storage container 14b is connected, and the front opening of freezing compartment 15 is provided with drawer-type insulated door 15a to which storage container 15b is connected.

[0014] A refrigeration cycle for cooling each storage compartment is incorporated within the insulated box 2. The refrigeration cycle has a well-known configuration including a refrigeration cooler 21, a freezing cooler 22, a compressor 23, a condenser (not shown), etc. The lower end on the back side of the insulated box 2 shown in Figure 2 is a machine room 19 in which the compressor 23, etc. are disposed.

[0015] As shown in Fig. 2, at the back of storage compartments 11, 12 in the refrigeration temperature range, there is provided refrigeration-side cooler compartment 25 accommodating refrigeration cooler 21, and cold air supply duct 26 connected to the top of cooler compartment 25. In this case, refrigeration-side cooler compartment 25 is a cooler compartment that also serves as an air duct, provided in the back insulating wall of insulated box body 2, extending behind chilled compartment 16 at the lowest level of refrigeration compartment 11 and vegetable compartment 12.

[0016] The refrigeration-side cooler chamber 25 is provided with an outlet 25a located at the upper front part thereof facing the chilled compartment 16, and an intake 25b facing the vegetable compartment 12 at the lower part. The cold air supply duct 26 has a predetermined width in the left-right direction (the direction perpendicular to the plane of the paper in FIG. 2 ) and is formed so as to extend upward from the cooler chamber 25 side along the back insulating wall of the refrigerator chamber 11. The cold air supply duct 26 is provided with a plurality of air outlets 26a that open inside the refrigerator chamber 11.

[0017] As shown in FIG. 2, a refrigeration blower 21f is disposed in the refrigeration-side cooler chamber 25, and the blowing action of the refrigeration blower 21f supplies the cold air generated in the cooler 21 from each outlet 26a or 25a of the supply duct 26 to the refrigeration chamber 11 side. In addition, although detailed illustration is omitted, the partition wall 3 (bottom plate of the refrigerator compartment 11) has communication openings located at both left and right corners on the rear side thereof, which connect the refrigerator compartment 11 and the vegetable compartment 12.

[0018] When refrigeration blower 21f is driven, the blowing action of blower 21f draws air into refrigeration-side cooler chamber 25 from inlet 25b on the vegetable compartment 12 side. The air then passes through refrigeration cooler 21 to become cold air, and is supplied into refrigeration compartment 11 from outlet 26a of cold air supply duct 26 (see the arrow in FIG. 2). The cold air supplied into refrigerator compartment 11 cools the interior of refrigerator compartment 11, and then a portion of the cold air flows into vegetable compartment 12 through the communication opening to cool vegetable compartment 12 (see arrow A0 in FIG. 3, which will be described later). The cold air that has cooled refrigerator compartment 11 and vegetable compartment 12 is again sucked into refrigerator-side cooler compartment 25 through intake opening 25b. In this way, the cold air circulates, cooling refrigerator compartment 11 and vegetable compartment 12.

[0019] A freezing-side cooler chamber 28, which also serves as an air duct, is provided at the back of the freezing temperature range storage chambers 13, 14, and 15 of the insulated box body 2. The freezing-side cooler chamber 28 houses a freezing cooler 22 in its lower part, and a freezing fan 22f is provided in its upper part. As shown in Figure 2, the freezer-side cooler chamber 28 is provided with multiple cool air outlets 28a located on its front side facing the storage chambers 13 to 15, as well as an intake port 28b facing the lower storage chamber 15.

[0020] When freezer blower 22f is driven, the air in lower freezer compartment 15 is drawn into freezer-side cooler chamber 28 through suction port 28b by the blowing action of blower 22f. The air then passes through freezer cooler 22, where it is cooled, becoming cold air, which is then supplied through outlet 28a to ice-making compartment 13, small freezer compartment 14, and freezer compartment 15. After cooling ice-making compartment 13, small freezer compartment 14, and freezer compartment 15, the cold air is again drawn into freezer-side cooler chamber 28 through suction port 28b. In this way, the cold air circulates, cooling ice-making compartment 13, small freezer compartment 14, and freezer compartment 15.

[0021] The cold air path is not limited to the circulating path (cold air path) as described above, but may be configured so that the cold air generated by the refrigeration cycle is supplied into each storage compartment by the above-mentioned blowing action. For example, in the vegetable compartment 12 shown in Fig. 3, a separate cold air supply port 30 can be provided in place of the communication port on the rear side of the partition wall 3. In this case, the cold air supply port 30 is disposed at the upper rear side of the vegetable compartment 12 as shown in the figure, as part of the cold air path, and a damper 30a is rotatably disposed at the tip side of the cold air supply port 30. By controlling the amount of rotation of the damper 30a, the opening degree of the cold air supply port 30 is adjusted so that the amount of cold air supplied into the vegetable compartment 12 is relatively increased or decreased. In either case, cold air is supplied to the vegetable compartment 12 from the upper rear side thereof, and a flow of cold air is formed toward the upper surface or front side of the vegetable container 5 as shown by arrow A0 in FIG.

[0022] The vertical cross-sectional view of FIG. 3 schematically shows the vegetable compartment 12 and the vegetable container 5 disposed therein. The vegetable container 5 is a container capable of storing food such as vegetables (see reference symbol "Ve" in FIG. 7 described later), and is configured with a humidity adjusting member 31 that adjusts the humidity of the storage space for the vegetables Ve. This configuration will be described with reference to FIGS. 4 and 5. Note that FIG. 4 is a plan view of the upper container 7 in the vegetable container 5, and FIG. 5 is a longitudinal sectional front view taken along line XX in FIG. 4.

[0023] As shown in FIG. 3, the vegetable container 5 includes a lower container 6 fixed to the back surface of the heat-insulating door 12a in the vegetable compartment 12, and an upper container 7 arranged on the upper surface side of the lower container 6. Of these, the upper container 7 is a compartmentalized container for storing vegetables Ve separately, and for example, in Figure 4, the portion forming the compartmentalized storage space 8a on the left side is the small container 8. Hereinafter, the lower container 6, the upper container 7, and the small container 8 will also be referred to simply as "containers" 6, 7, and 8, respectively, and these will be collectively referred to as the vegetable container 5.

[0024] 3, the lower container 6 constituting the vegetable container 5 is made of, for example, an opaque plastic material and is a box-shaped case with an open top and a relatively deep bottom. The lower container 6 is held slidably in the front-to-rear direction by a slide rail (not shown) within the vegetable compartment 12, and is moved in and out of the vegetable compartment 12 together with the upper containers 6 and 8 when the insulated door 12a is opened or closed.

[0025] A partition wall 33 is provided inside the lower container 6 shown in Figure 3 at a position slightly toward the front. The partition wall 33 is formed in a plate shape from, for example, a transparent plastic material, and divides the interior of the lower container 6 into a main storage section 6a and a sub-storage section 6b. The main storage section 6a is a storage space formed behind the partition wall 33 and occupies most of the vegetable container 5, including the rear part. The sub-storage section 6b is a space formed on the insulated door 12a side, which is the front side of the partition wall 33, and occupies the front part of the vegetable container 5.

[0026] The upper container 7 is made of, for example, the same transparent plastic material as the partition wall 33, and is a box-shaped case with an open top and a shallower bottom than the lower container 6. Although detailed illustration is omitted, the upper container 7 is detachably and movably placed on a flange formed on the side of the upper surface of the lower container 6. This allows the upper container 7 to also function as a cover for the lower container 6, particularly the main storage section 6a.

[0027] As shown in Figure 3, the front-to-rear dimension L1 (see Figure 4) of the upper container 7 is set to be smaller than the front-to-rear dimension of the lower container 6. Therefore, when the upper container 7 is placed on top of the lower container 6, an open section 34 that is not blocked by the upper container 7 is formed at the rear upper part of the main storage section 6a. 3 and 4, a handle 35 is provided at the upper edge of the front wall of the upper container 7. The handle 35 extends from the upper edge of the front wall of the upper container 7 so as to slope downward and forward. This allows the user to place their fingers on the handle 35 as a handhold when moving the upper container 7 back and forth or when attaching or detaching the upper container 7 from the lower container 6.

[0028] 4, a partition wall 36a is provided inside upper container 7 at a position slightly to the left. Partition wall 36a divides the interior of upper container 7 into a storage section 8a for small container 8 and the remaining storage section 7a. Storage section 8a for small container 8 is located on the left side of partition wall 36a and is formed as a storage space independent of storage section 7a on the right side of partition wall 36a.

[0029] In this embodiment, in Figure 4, the left storage section 8a indicated by the width dimension W1 is also referred to as the "storage space 8a of the container 8," and the right storage section 7a indicated by the width dimension W2 is also referred to as the "storage space 7a of the container 7." The container 8 has the open portion of the storage space 8a covered by the lid 38, while the container 7 has the open portion of the storage space 7a left open and uncovered.

[0030] 4 can be integrally formed by resin molding, but the dimensions and shapes of each can be set and changed as appropriate. For example, container 8 may be configured to have a wider width "W1+W2" and eliminate the storage space 7a on the right side (eliminate container 7 entirely), or container 8 and the container 7 to its right may be formed separately as separate, independent containers 8, 7. The following description will focus on the configuration of container 8.

[0031] As shown in FIGS. 4 and 5, the container 8 comprises a container body 36 and the lid 38 that covers an upper opening 37 of the container body 36. The container body 36 is made of, for example, the transparent plastic material and is formed into a rectangular box shape that is slightly elongated in the front-to-rear direction. In this case, as shown in Figures 4 and 5, the container body 36 integrally includes peripheral walls including the partition wall 36a as the right side wall 36a, the left side wall 36b, the front wall 36c, and the rear wall 36d, and a bottom wall 36e. The top surface of the container body 36 is an open portion 37 that opens the storage space 8a into the vegetable compartment 12.

[0032] The lid 38 is made of, for example, the transparent plastic material, and has a rectangular plate shape that is slightly elongated in the front-rear direction and has a size corresponding to the opening 37 of the container body 36 . The lid 38 is provided with a humidity adjusting member 31 that adjusts the humidity in the storage space 8a of the container 8.

[0033] 4 and 5, the humidity adjusting member 31 is attached to the left-right center of the lid 38, slightly toward the rear. An opening 38a for the humidity adjusting member 31 is formed in the lid 38 at this attachment position, and the humidity adjusting member 31 is fitted in such a way as to close the opening 38a. As a result, the humidity adjusting member 31 is positioned such that its upper surface faces the space on the ceiling side (partition wall 3 side) of the vegetable compartment 12, and its lower surface faces the storage space 8a. When the open portion 37 of the container body 36 is covered with the lid 38, the vegetables Ve in the storage space 8a can be seen through the lid 38 (excluding the humidity adjusting member 31).

[0034] The humidity adjusting member 31 shown in Figures 4 and 5 is composed of multiple layers, for example, including a nonwoven fabric that allows air to pass through and a breathable film, and is formed into a rectangular sheet or plate as a whole. This nonwoven fabric carries moisture-retaining particles, and in an environment where dryness and humidity alternate, it adjusts humidity by absorbing moisture at high humidity and releasing moisture at low humidity. In this case, the moisture-retaining particles are formed into a powder form using a polymer or the like, or are formed into fine particles to increase the surface area in contact with air, and are carried by the nonwoven fabric of the humidity adjusting member 31. The breathable film is, for example, a porous body having many fine pores, which allows the passage of gaseous water vapor but restricts the passage of liquid water. In this way, the humidity adjusting member 31 has the function of adjusting the humidity of at least the storage space 8a, and has a laminated structure including a nonwoven fabric and a breathable film, but can also be configured using a catalytic functional material 31a that has a sterilization effect, etc.

[0035] 5, reference numeral 31a schematically indicates a catalytic substance, and a carrier other than the nonwoven fabric may be used as the carrier. The catalytic substance 31a is, for example, an inorganic catalyst made of a metal oxide such as manganese dioxide, or an organic catalyst such as an artificial enzyme, impregnated with an adsorbent such as activated carbon, and by supporting this on an air-permeable carrier made of an inorganic or organic material, deodorization and sterilization can be performed. 4 and 5, the humidity adjusting member 31 occupies a central portion of the lid body 38 (a portion slightly toward the rear in FIG. 5) and has a similar shape to the lid body 38, which allows the humidity adjusting member 31 to occupy a relatively large area. The thickness of the humidity adjusting member 31 is set to be approximately the same as the thickness of the lid body 38.

[0036] The cover 38 is provided with a plurality of ventilation sections 41 positioned around the outer periphery of the humidity adjusting member 31. The ventilation sections 41 are arranged linearly at equal intervals along the long sides (long sides on the left and right sides in FIG. 4) extending in the longitudinal direction, i.e., the front-to-rear direction, of the humidity adjustment member 31. In this case, for example, five ventilation sections 41 are provided on the left side of the humidity adjustment member 31 and five on the right side, so that the ventilation sections 41 are arranged symmetrically on the left and right sides.

[0037] 4 and 5, the plurality of ventilation sections 41 are all rectangular holes that penetrate the lid body 38 in the vertical direction, which is the plate thickness direction, and are also referred to as "vent holes 41." In other words, the ventilation holes 41 are formed in the lid body 38 so as to communicate the space within the vegetable compartment 12 with the storage space 8a, and function as ventilation sections 41. 4, the plurality of ventilation holes 41 are formed at positions slightly spaced to the left of the left side of the humidity adjusting member 31 on the lid 38 or slightly spaced to the right of the right side, but the positions and number of the ventilation holes 41 around the humidity adjusting member 31 can be changed as appropriate. The ventilation holes 41 may also be round holes, and the dimensions and shape thereof may also be changed as appropriate. In any case, the size and number of the ventilation holes 41 are set so that cool air flows into the storage space 8a of the container 8 at an appropriate rate, and a downward flow of cool air is formed through the ventilation holes 41 (see arrow A1 in Figure 5).

[0038] Next, the operation of the above configuration will be described. As shown by arrow A0 in FIG. 3, cold air is supplied to the vegetable compartment 12 from a cold air supply port 30 at the upper rear side thereof, and a flow of cold air directed toward the upper surface or front side of the vegetable container 5 is formed.

[0039] At this time, as shown in Figure 5, part of the cool air flowing over the upper side of the lid 38 of the container 8 passes through the humidity adjusting member 31 and flows into the storage space 8a (see arrow A0'). As a result, cool air whose humidity has been adjusted by the humidity adjusting member 31 is supplied to the inside of the container 8. Furthermore, even if there is an odor or airborne bacteria in the vegetable compartment 12, the humidity adjusting member 31 containing the catalytic functional material 31a can deodorize and disinfect the cool air as it passes through the member 31. In this way, a flow of cool air is formed inside the container 8 via the humidity adjusting member 31 and directed downward therefrom, as indicated by the arrow A0' in the center of FIG.

[0040] Furthermore, part of the cool air flowing over the upper surface of the lid 38 of the container 8 flows into the storage space 8a through the multiple vent holes 41 (see arrow A1). That is, the cool air is supplied downward into the container 8 through the multiple vent holes 41 on both the left and right sides around the humidity adjusting member 31 of the lid 38. In this case, as shown by arrow A1' on the left side of the figure, the cold air flowing in from the air vent 41 on the left side of the humidity adjustment member 31 flows downward along the left side wall 36b or hits the lower bottom wall 36e or vegetables, etc. Ve due to natural convection caused by the temperature difference within the storage space 8a, and then turns back upward near the center in the left-right direction (towards the upper humidity adjustment member 31), forming a circulating flow of cold air.

[0041] In contrast, the cold air flowing in through the air vent 41 on the right side of the humidity adjusting member 31 flows downward along the right side wall 36a or hits the bottom wall 36e below or vegetables, etc. Ve due to natural convection within the storage space 8a, and then forms a flow of circulating cold air that turns back upward near the center in the left-right direction. In this way, in the storage space 8a of the container 8, the above-mentioned inflow of cold air and natural convection agitate the air with the pair of cold air flows (arrows A1', A1') on the left and right as shown in Figure 5 and the opposite cold air flow (arrow A0') from the humidity adjustment member 31 side, and by exposing the entire area under the humidity adjustment member 31 to this air, humidity is maintained at an appropriate level and efficient deodorization and sterilization are also possible.

[0042] Unlike this embodiment, if a container without ventilation holes 41 is used, natural convection is unlikely to occur within the container, and if airborne bacteria enter the container when the lid is opened or closed, there is a risk that they will remain within the container. In contrast, in the container 8 of this embodiment, the lid 38 is provided so that the humidity adjustment member 31 is exposed to the air in the storage space 8a, and a plurality of air vents 41 are arranged around it, particularly on both the left and right sides, aligned in the longitudinal direction of the humidity adjustment member 31. Therefore, even if airborne bacteria enter when the lid 38 is opened or closed, as described above, air can be efficiently brought into contact with the humidity adjustment member 31 along its entire length, and coupled with the agitation action of the air in the storage space 8a, the deodorizing and sterilizing effects of the humidity adjustment member 31 can be enhanced, and an appropriate humidity can be maintained, suppressing bacterial growth.

[0043] As described above, the container 8 of this embodiment includes the lid 38 that covers the open portion 37 of the container body 36, and the humidity adjusting member 31 that adjusts the humidity in the storage space 8a of the container 8. The humidity adjusting member 31 is provided so as to be exposed to the air in the storage space 8a by the lid 38, and at least one ventilation portion 41 is provided around the humidity adjusting member 31.

[0044] This allows the humidity adjusting member 31 to be exposed to the air in the storage space 8a in the lid 38, and the lid 38 can be used to ensure a sufficient contact area between the air in the storage space 8a and the humidity adjusting member 31. Also, as shown by arrow A1 in Fig. 5, for example, cool air can be introduced from the ventilation part 41 around the humidity adjusting member 31, allowing air to come into contact with the humidity adjusting member 31 by natural convection, making it possible to maintain a humidity level suitable for preserving the freshness of vegetables Ve in the container 8.

[0045] The ventilation section 41 connects the space inside the storage chamber 12 in the lid body 38 with the storage space 8a of the container 8, and the air in the storage space 8a is agitated by the air flowing in from the ventilation section 41 and comes into contact with the humidity adjustment member 31. As a result, for example, as shown by arrow A1' in Figure 5, the cold air flowing in from at least one ventilation section 41 can agitate the air in the storage space 8a and bring it into contact with the humidity adjustment member 31, which is suitable for adjusting the humidity in the storage space 8a or for maintaining the freshness of vegetables, etc. Ve.

[0046] <Other embodiments> 6 to 12 show the second and subsequent embodiments of the present invention. Below, we will describe the points that are substantially different from the previously described embodiments.

[0047] 6(a) is a vertical sectional front view of the container 8 shown together with the ventilation part 42 of the second embodiment, and (b) is an explanatory view showing an enlarged view of the vicinity of the ventilation part 42. The ventilation part 42 of the second embodiment differs from the ventilation part 41 of the first embodiment in the following points. That is, as shown in FIG. 6(a), the lid 38 is provided around the outer periphery of the humidity adjusting member 31 with a plurality of ventilation sections 42 (hereinafter also referred to as "vent holes 42") that are inclined relative to the vertical direction.

[0048] Of these, the air vents 42 arranged side by side on the left side of the humidity adjusting member 31 are all inclined downwards in a direction approaching the humidity adjusting member 31. In this case, in Figure 6(a), the arrow A2 on the left side indicates the directional direction of the cool air passing through the left air vent 42 (the downward right direction that is the penetration direction of the air vent 42), and the inclination angle α between this directional direction and the vertical direction is set so that the cool air does not directly hit the vegetables Ve inside and flows toward the center where the humidity adjusting member 31 is located.

[0049] In contrast, the air vents 42 arranged side by side on the right side of the humidity adjusting member 31 are all inclined downwards, approaching the humidity adjusting member 31. The arrow A2 on the right side of the figure indicates the direction (downward and left) of the cool air passing through the right air vent 42, and the angle of inclination α between that direction and the vertical direction is set so that the cool air does not directly hit the vegetables Ve inside and flows toward the center where the humidity adjusting member 31 is located.

[0050] 6(b), the direction of the cold air passing through the vent hole 42 (arrow A2) can be roughly seen to coincide with the penetration direction, which is the direction in which the vent hole 42 extends (although arrow A2 is shown as a straight line in (a)), but strictly speaking, the cold air flowing downward through the vent hole 42 hits the inclined inner peripheral surface of the vent hole 42 and snakes gently toward the storage space 8a. In this sense, or in the sense that the cold air flowing in through the vent hole 42 does not flow directly downward toward the bottom wall 36e, it can be said that the cold air is unlikely to directly hit the vegetables Ve inside.

[0051] Thus, as shown by arrow A1' on the left side of Figure 6(a), the cold air flowing in from the air vent 42 on the left side of the humidity adjustment member 31 flows toward the central humidity adjustment member 31 or, due to natural convection within the storage space 8a, combines with the direction of the cold air flowing downward in the center (see arrow A0') and flows toward the lower bottom wall 36e and vegetables, etc. Ve, and then forms a flow of cold air that circulates by turning back to the left side.

[0052] In contrast, the cold air flowing in from the air vent 42 on the right side of the humidity adjusting member 31 flows toward the central humidity adjusting member 31 or, due to natural convection within the storage space 8a, combines with the downward flow of cold air in the center and flows toward the lower bottom wall 36e and vegetables, etc. Ve, and then forms a flow of cold air that circulates by turning back to the right side. Thus, in the storage space 8a of the container 8, due to the direction of the inflow of the cold air and natural convection described above, a pair of cold air flows (arrows A2', A2') are formed on the left and right as shown in Figure 6, heading toward the humidity adjustment member 31, and these flows combine with the direction of the cold air (arrow A0') from the humidity adjustment member 31 side to agitate the air, so that the entire area of ​​the underside of the humidity adjustment member 31 is exposed to this air.

[0053] As described above, the ventilation section 42 of the second embodiment connects the space within the storage chamber 12 in the lid body 38 with the storage space 8a of the container 8, and is formed as a connecting passage having an inclined shape so that the air flowing into the storage space 8a through the ventilation section 42 flows toward the humidity adjustment member 31 in the storage space 8a. According to this, by forming the ventilation section 42 as a communication passage such as the air vent 42, the cold air flowing in from the communication passage is less likely to directly hit the vegetables Ve on the bottom wall 36e side, making it possible to agitate the air in the storage space 8a while preventing the vegetables Ve from drying out. Also, because the cold air flowing in from the communication passage flows toward the humidity adjustment member 31, it is easy for the air to come into contact with the humidity adjustment member 31, and humidity can be suitably maintained.

[0054] 7(a) is a vertical sectional front view of the container 8 shown together with the ventilation part 43 of the third embodiment, and (b) is an explanatory view showing an enlarged view of the vicinity of the ventilation part 43. The ventilation part 43 of the third embodiment differs from the ventilation part 42 of the second embodiment in the following points.

[0055] That is, the ventilation section 43 shown in Figure 7(a) is, roughly speaking, a ventilation hole 43 with an overall inclination angle set to α, and is formed so that the cool air passing through the ventilation hole 43 does not directly hit the vegetables etc. Ve inside and flows toward the center where the humidity adjustment member 31 is located. 7(b), the vent hole 43 is formed in the shape of an inverted truncated cone having a large-diameter opening 43a on the upper surface of the lid 38 and a small-diameter opening 43b on the lower surface, and the inclination angle between the central axis and the vertical direction is set to α. In this case, the inner diameter of the vent hole 43 decreases from the large-diameter opening 43a to the small-diameter opening 43b, and the small-diameter opening 43b is shifted toward the humidity adjustment member 31 with respect to the large-diameter opening 43a.

[0056] Therefore, as shown in the same figure (b), the cool air (arrow A3) flowing in from the large diameter opening 43a in the vertical downward direction in the ventilation hole 43 hits the inclined inner surface of the ventilation hole 43, and combined with the shape of the inner surface which narrows as it approaches the small diameter opening 43b, it is weakened (its inflow is suppressed) as shown by the thin arrow A3, and then it snakes gently towards the storage space 8a.

[0057] Therefore, in the storage space 8a of the container 8 shown in Fig. 7(a), the amount of cool air flowing in through the air vent 43 is limited, resulting in a slower and gentler air stirring action. In this case, the air flows indicated by arrows A3', A0', and A3' in Fig. 7(a) stir the air in the storage space 8a more slowly than the air flows indicated by arrows A2', A0', and A2' in Fig. 6(b).

[0058] As described above, in the ventilation section 43 of the third embodiment, the outer portion facing the space inside the storage chamber 12 is larger than the inner portion facing the storage space 8a. According to this, the ventilation section 43 as a communication passage such as the air vent 43 has a large diameter opening 43a on the outer part that is larger than the small diameter opening 43b on the inner part, so that cool air can flow in efficiently from the outer part while restricting the inflow into the storage space 8a at the inner part, thereby more slowly stirring the air in the storage space 8a. In addition, the ventilation section 43 is formed as a communicating passage that is inclined so that air flows toward the humidity adjustment member 31, thereby achieving the same effects as the above embodiment, such as making it easier for air to come into contact with the humidity adjustment member 31.

[0059] 8(a) is a vertical sectional front view of the container 8 shown together with the ventilation part 44 of the fourth embodiment, and (b) is an explanatory diagram showing an enlarged view of the vicinity of the ventilation part 44. Note that in FIG. 8(a) as a schematic diagram, the thicknesses of the lid body 38 and the humidity adjusting member 31 are slightly different, but it goes without saying that in embodiments other than the fourth embodiment, the thickness dimensions of both the lid body 38 and the humidity adjusting member 31 can be set to different dimensions or approximately the same dimensions.

[0060] As shown in the enlarged view of Figure 8(b), the ventilation section 44 is an "L"-shaped ventilation hole 44 in vertical cross section, in which a large-diameter vertical hole 44a on the upper surface side of the lid body 38 and a small-diameter horizontal hole 44b on the lower surface side are connected to each other. In this case, the inner diameter of the large-diameter vertical hole 44a is set larger than that of the small-diameter horizontal hole 44b in the ventilation hole 44. The large-diameter vertical hole 44a extends in the thickness direction of the lid 38 and is formed as a first communication passage that opens at its upper end and communicates with the small-diameter horizontal hole 44b at its lower end. On the other hand, the small diameter horizontal hole 44b extends in a direction along the lower surface, which is the main surface of the humidity adjustment member 31, and is formed as a second communication passage that communicates with the large diameter vertical hole 44a on its left-right outer side and opens on the inner side, which is the humidity adjustment member 31 side.

[0061] Therefore, as shown in Figures 8(a) and (b), the cool air (arrow A4) flowing in downward from the large-diameter vertical hole 44a in the ventilation hole 44 hits the connecting part with the small-diameter horizontal hole 44b, and combined with the shape of the small-diameter horizontal hole 44b, which has a relatively small diameter and extends toward the humidity adjustment member 31, the flow into the storage space 8a is suppressed (weakened) and the air is directed toward the humidity adjustment member 31.

[0062] 8(a), the amount of cold air flowing in through the vent holes 44 is limited, and a flow is formed along the underside of the humidity adjusting member 31 as shown by arrow A4. In this case, the flow of cold air indicated by arrow A4, or the air flows indicated by arrows A4', A0', and A4', is less likely to directly hit the vegetables Ve inside, and the air is more likely to come into contact with the humidity adjusting member 31, and a slower air agitation effect can be obtained.

[0063] As described above, the ventilation section 44 of the fourth embodiment has a bent shape at the connection between the first communication passage that faces the outer space and extends in the thickness direction of the lid body 38, and the second communication passage that faces the storage space 8a and extends in a direction along the main surface of the humidity adjustment member 31. According to this, for example, the ventilation hole 44 as the ventilation section 44 is configured as a first communication passage and a second communication passage in which the large diameter vertical hole 44a and the small diameter horizontal hole 44b are bent at the connection part between the two, so that the cold air is less likely to directly hit the vegetables Ve inside and can be made to easily come into contact with the humidity adjustment member 31. Furthermore, for example, the large-diameter vertical hole 44a of the ventilation hole 44 as the ventilation section 44 is larger than the small-diameter horizontal hole 44b of the inner part, so that cool air can flow in efficiently from the outer part while restricting the flow into the storage space 8a at the inner part, thereby achieving the same effect as the above embodiment, such as being able to stir the air in the storage space 8a more slowly.

[0064] 9(a) is a vertical front view of the container 8 showing the holding frame 50 of the humidity adjusting member 31 in the fifth embodiment and the surrounding ventilation portion 45, and (b) is a plan view showing the humidity adjusting member 31 held by the holding frame 50. Also, FIGS. 10(a) and 10(b) show how the holding frame 50 is attached and detached together with the humidity adjusting member 31.

[0065] In this way, the humidity adjusting member 31 of the fifth embodiment is held by the holding frame 50 and is configured as a unit 310 integrated with the holding frame 50. The holding frame 50 shown in FIGS. 9(a) and 9(b) is made of, for example, a plastic material, and is formed into a rectangular frame shape that matches the outer shape of the humidity adjusting member 31 as a whole.

[0066] As shown in FIG. 10(a), the holding frame 50 is integrally formed with a holding portion 50c that is substantially U-shaped in vertical cross section, and engagement portions 50a and 50b that protrude above the holding portion 50c. In the holding frame 50, the holding portion 50c holds the adjustment member 31 by clamping the edge of the adjustment member 31 with the U-shaped portion. As shown in Figures 9(b) and 10(a), the engagement portions 50a and 50b are located in the middle of the left and right sides of the holding portion 50c in the front-to-rear direction and are formed to protrude upward. The tip sides of the engagement portions 50a and 50b are inclined to form a V-shape as shown in Figure 10(a), making it easy for the user to hook their fingertips, etc.

[0067] In this way, the humidity adjustment member 31 is attached to the opening 51 of the lid 38 as a unit 310 held by the holding portion 50c of the holding frame 50. When the unit 310 is attached to the opening 51, the engagement portions 50a and 50b of the holding frame 50 slightly protrude from the top surface of the lid 38 (see FIG. 9(a)), and therefore function as handles.

[0068] As shown in FIG. 10(a), the opening 51 of the cover 38 is formed to a size that allows the unit 310 to be attached. In this case, the opening 51 serves as the mounting portion, and the holding portion 50c on the outer circumferential side of the humidity adjustment member 31 serves as the mounting portion, with a receiving portion 51c formed around the entire periphery of the lower end of the inner circumferential surface of the opening 51. The receiving portion 51c of the opening 51 protrudes toward the inner circumferential side and is configured to receive the holding frame 50 from below. Furthermore, a pair of left and right engagement claws 51a, 51b are formed on the inner peripheral surface of the opening 51, positioned at the upper end thereof, and corresponding to the engagement portions 50a, 50b of the holding frame 50. Although not shown in detail, engagement holes are formed in the engagement portions 50a, 50b of the holding frame 50, and the engagement claws 51a, 51b of the opening 51 engage with the respective engagement holes, thereby locking the unit 310 and attaching it to the opening 51 (see FIG. 9(a)).

[0069] Here, the clearance (gap) between the inner peripheral side of the opening 51 in the lid body 38 and the opposing outer peripheral side of the holding portion 50c of the humidity adjustment member 31 functions as a ventilation portion 45 that connects the space within the vegetable compartment 12 with the storage space 8a. In detail, the ventilation section 45 is a communication passage around the humidity adjustment member 31 and extending over the entire circumference of the holding section 50c, and is composed of a first communication passage 45a consisting of the gap between the inner surface of the opening 51 shown in Figure 9(a) and the outer surface of the holding section 50c, and a second communication passage 45b consisting of the gap between the receiving section 51c and the underside of the holding section 50c.

[0070] In other words, the ventilation section 45 is made up of communication passages 45a, 45b that are bent at the connection between a first communication passage 45a that faces the space above it and extends in the thickness direction of the lid body 38, and a second communication passage 45b that faces the storage space 8a and extends in a direction along the underside of the humidity adjustment member 31. Therefore, the flow of cold air (arrow A5) flowing in from the ventilation section 45 shown in Figure 9(a) is in the same direction as the flow of cold air (arrow A4) flowing in from the ventilation hole 44 in Figure 8(a), but the communication passages 45a, 45b of the former 45 are provided around the entire circumference of the holding frame 50.

[0071] These communicating passages 45a, 45b extending all around the circumference form a flow of cold air from both left and right ends of the humidity adjusting member 31 toward the center, as shown by arrow A5 in Figure 9(a), as well as a flow of cold air from both front and back ends toward the center. Therefore, in the storage space 8a of the container 8 shown in Figure 9(a), the cold air flowing in from the ventilation section 45 is weakened at the bent parts of the connecting passages 45a, 45b and heads toward the center of the humidity adjustment member 31, and the flow of cold air indicated by the arrow A5 or the air flow indicated by the arrows A5', A0', A5' is symmetrical when viewed in both the vertical front view of the same figure and the vertical side view not shown, making it difficult for the cold air to directly hit the vegetables Ve inside and making it easier for the air to come into contact with the humidity adjustment member 31, resulting in an optimal air stirring effect.

[0072] The unit 310 can be attached or detached simply by engaging or disengaging the engagement claws 51a, 51b of the opening 51 in the lid 38 with the engagement holes of the engagement portions 50a, 50b of the holding frame 50. 10(b), for example, a user places a fingertip on the tip of one of the engagement portions 50a of the holding frame 50 and pulls it up. As a result, the engagement portion 50a disengages from the engagement claw 51a of the opening 51 due to its own flexibility or the play, while the other engagement portion 50b remains engaged with the engagement claw 51b, allowing only one side of the holding frame 50 to be lifted. Next, by lifting the holding frame 50 in the direction in which the engaging portions 50b are disengaged from the engaging claws 51b, the entire unit (together with the humidity adjusting member 31) can be removed from the opening 51 (see FIG. 10(a)). In this way, the unit 310 can be easily removed from the lid 28, and maintenance such as cleaning or replacing the humidity adjusting member 31 is also easy.

[0073] 10(a), the user pushes the unit 310 into the opening 51 from above. As a result, the left and right engagement portions 50a, 50b of the holding frame 50 come into contact with the engagement claws 51a, 51b and bend inward, and the holding frame 50 is pushed in until the engagement claws 51a, 51b are locked into their respective engagement holes, thereby allowing the entire unit to be fitted into the opening 51. Alternatively, as shown in FIG. 10(b), the unit 310 may be tilted and inserted into the opening 51 by pushing in the engaging portions 50a and 50b one by one so that they engage with the engaging claws 51a and 51b. The holding frame 50 only needs to be configured to be detachable as an attachment portion on the outer periphery of the humidity adjusting member 31, and can be modified as appropriate as shown in Figs. 11 and 12 described later.

[0074] As described above, the cover body 38 of the fifth embodiment has an opening 51 to which the humidity adjusting member 31 is removably attached, and the ventilation section 45 is composed of communicating passages 45a, 45b, with the opening 51 as the attachment portion and the outer circumferential side of the humidity adjusting member 31 as the attachment portion, and the gap between the inner circumferential side of the attachment portion and the outer circumferential side of the attachment portion opposite it. This allows the humidity adjusting member 31 to be removed from the opening 51 of the lid 38 and to be cleaned, replaced, or otherwise maintained. Furthermore, the ventilation section 45 is composed of communication passages 45a, 45b that utilize the gap around the mounting section (e.g., holding section 50c) on the outer periphery of the humidity adjusting member 31, so that air can flow into the storage space 8a from the outer periphery of the mounting section of the humidity adjusting member 31 without providing any other separate ventilation section.

[0075] In addition, the ventilation section 45 has a curved shape at the connection between the first communication passage 45a, which faces the outside space and extends in the thickness direction of the lid body 38, and the second communication passage 45b, which faces the storage space 8a and extends in a direction along the main surface of the humidity adjustment member 31, so that the cold air is less likely to directly hit the vegetables etc. Ve inside and can be made to easily come into contact with the humidity adjustment member 31, thereby achieving the same effects as the above embodiment.

[0076] FIG. 11(a) is a plan view of a unit 311 including a holding frame 52 of the sixth embodiment, and (b) is a left side view in vertical section of the unit 311 and its vicinity. The holding frame 52 and the ventilation part 46 of the sixth embodiment differ from the holding frame 50 and the ventilation part 45 of the fifth embodiment in the following points.

[0077] That is, the holding frame 52 is detachably attached to the opening 53 of the lid 38 as a unit 311 integral with the humidity adjusting member 31 to be held by the holding frame 52. 11(a) and 11(b), the holding frame 52 is provided with engagement portions 52a, 52b located at the left-right middle of both front and rear sides of the holding portion 50c. The engagement portions 52a, 52b extend upward from the lower end of the holding portion 50c as the base end, and are inclined outward in the front-rear direction so as to move away from the holding portion 50c as they extend upward. Furthermore, as shown in FIG. 11(b), the engagement portions 52a, 52b are each formed with recesses 54a, 54b recessed into their outer surfaces in the front-rear direction.

[0078] 11(b), a receiving portion 53c that receives the holding frame 52 from below is formed around the entire periphery of the lower end of the inner circumferential surface of the opening 53 of the lid 38. Also, a pair of front and rear engaging claws 53a, 53b that correspond to the engaging portions 52a, 52b of the holding frame 52 are formed on the inner circumferential surface of the opening 53, positioned on the upper end side. The engaging claws 53a, 53b engage with recesses 54a, 54b of the engaging portions 52a, 52b to lock the holding frame 52 (unit 311).

[0079] Here, the gap between the inner peripheral side surface of the opening 53 in the lid 38 and the opposing outer peripheral side surface of the holding portion 50c of the humidity adjusting member 31 functions as the ventilation portion 46. In this case, the ventilation portion 46 is made up of a first communication passage 46a formed by the gap between the inner peripheral surface of the opening 53 and the outer peripheral surface of the holding portion 50c shown in Figures 11(a) and 11(b), and a second communication passage 46b formed by the gap between the receiving portion 53c and the underside of the holding portion 50c.

[0080] For ease of explanation, Figure 11 is a schematic diagram in which the first communication passage 46a shown in (a) is exaggerated to be larger than the second communication passage 46b shown in (b), but the respective sizes and gaps can be set appropriately by adjusting the engagement position of the holding frame 52 in the lid body 38 or by adjusting the dimensions of the opening 53, etc.

[0081] Therefore, the ventilation section 46 of the sixth embodiment can also form a flow of cool air that flows into the storage space 8a of the container 8, as indicated by arrow A5 in Fig. 9. Furthermore, the same effects as those of the above-described embodiments can be achieved, such as the fact that the unit 311 can be attached and detached with a simple configuration that utilizes the flexibility of the engagement sections 52a, 52b of the holding frame 52 or by engaging the recesses 54a, 54b of the engagement sections 52a, 52b with the engagement claws 53a, 53b. In addition, in Figure 11(b), the catalytic functional material 31a is omitted from the humidity adjustment member 31, and in (a) the humidity adjustment member 31 and the holding frame 52 are formed in an approximately square shape, but the functions other than the humidity adjustment function of the humidity adjustment member 31, as well as the dimensions and shape, can be changed as appropriate.

[0082] The present invention is not limited to the embodiments and modifications described above and shown in the drawings, but can be practiced by appropriately modifying the embodiments or modifications, for example, by combining the embodiments or modifications.

[0083] For example, as shown in FIG. 12, the holding frame 50 may have only the holding portion 50c, without the engaging portions 50a and 50b (see FIG. 10(a)). In this case, the inner peripheral surface of the opening 51 of the lid 38 is provided with, for example, an "L"-shaped abutment portion 61, as shown in FIG. 12, instead of the engaging claws 51a and 51b of FIG. 10(a). The abutment portion 60 is a rib that protrudes from multiple locations (for example, four locations) around the inner peripheral surface of the opening 51, and abuts against the outer peripheral surface and bottom surface of the holding portion 50c, respectively, to secure gaps that form the communication paths 45a and 45b of the ventilation portion 45.

[0084] The contact portion 61 may be configured as a small convex protrusion instead of the L-shaped rib shown in Fig. 12. The unit 310 can be attached to the lid 38 by pushing the unit 310 into the opening 51 from above and bringing the lower surface of the holding portion 50c into contact with the contact portion 61 on the receiving portion 51c. In any case, as is clear from a comparison between FIG. 12 and FIG. 9(a), and as indicated by the same arrow A5, it is possible to form the intended communication paths 45a, 45b through which cool air can flow.

[0085] Although one embodiment of the present invention has been described above, this embodiment is presented as an example and is not intended to limit the scope of the invention. This novel embodiment can be embodied in various other forms, and various omissions, substitutions, and modifications can be made without departing from the spirit of the invention. The present embodiment and its modifications are included within the scope and spirit of the invention, and are also included in the inventions and their equivalents as defined in the claims.
