Description

  The present invention relates to a refrigerator, and more particularly to a refrigerator with improved food visibility and humidity control in a refrigerator storage case.

  Conventionally, for example, “as shown in FIG. 2 and FIG. 3, the storage container 10 has a normal storage chamber 11 used for storing vegetables for about a week by a partition plate 10 a erected in the center, It is divided into a long-term storage chamber 12 that is used when storing over the above-mentioned long period of time. “Of the two storage chambers 11 and 12, the upper surface opening port of the long-term storage chamber 12 is transparent as an opening / closing member. There is a case in which the upper opening opening serving as an entrance / exit of the normal storage chamber 11 is closed by a cover 15 covering the entire upper surface of the storage container 10 (see Patent Document 1).

  In such a case, “the normal storage chamber 11 and the long-term storage chamber 12 are closed by the cover 15 and the lid 13, so that the storage chambers 11 and 12 are kept in a high humidity state”. Patent Document 1).

  Also, for example, “The vegetable storage chamber has a storage case in which the top opening can be opened and closed with a lid and contains food such as vegetables, and the storage case in a state of closing a hole formed in the storage case. A humidity control case that is detachably attached to the outside and houses the humidity control material, wherein the humidity control material is covered with a porous film having vent holes with a predetermined pore diameter, At least one of the material and the porous film is impregnated with a fungicide, and at the same time, the opening of the humidity control material case faces the hole, and the humidity control material in the humidity control material case is interposed through the porous film. The food storage is characterized by being separated from the atmosphere in the storage case ”(see Patent Document 2).

  In such a case, “the inside of the storage is kept hygienic and the range of humidity adjustment in the storage is increased, which is extremely practical” (see Patent Document 2).

  Further, for example, there is a method in which a humidity control member is formed by combining a porous material having a pore diameter in a predetermined range and fine particles of hygroscopic organic material and the humidity control member is installed in a refrigerator (see Patent Document 3). .

  In such a case, “It is possible to complement each other's drawbacks while taking advantage of the former's autonomous humidity control ability and the latter's ability to prevent condensation, and as a result, without causing condensation. The effect is that the vegetable compartment can be kept at high humidity "(see Patent Document 3).

JP-A-6-18152 (paragraph 0012, paragraph 0013, paragraph 0018, FIG. 2, FIG. 3) Japanese Patent No. 2999642 (Claim 1, paragraph 0009) Japanese Patent No. 3563286 (paragraph 0019, paragraph 0032)

  As described above, in the conventional example (Patent Document 1), the vegetable compartment is partitioned in the width direction, and a lid is provided on the upper opening of the partitioned compartment, thereby improving the visibility of the food stored in the vegetable compartment. At the same time, it was improving the quality of the vegetable room. However, there has been a problem that dew condensation occurs due to the inability to adjust the humidity in the vegetable compartment.

  In addition, in the conventional example (Patent Document 2), in order to maintain the humidity inside the storage case of the vegetable storage room, a hole provided in advance on the front surface of the storage case with a lid on the opening above the storage case Humidity control was performed by providing a humidity control material on the outside of the storage case so as to close the part. However, since the humidity conditioner regulates the humidity of the entire storage case, the space to be controlled by the humidity conditioner is relatively large. As a result, the entire storage case cannot be fully conditioned, and a large amount of dew condensation occurs. Hereinafter, the storage case is referred to as a storage chamber.

  Moreover, in the conventional example (patent document 3), when installing the humidity control member, the opening of the target case was not closed with a lid. For this reason, the space for humidity control with respect to the humidity control member is relatively large. As a result, the entire case could not be fully conditioned, and a large amount of dew condensation occurred.

  As described above, the conventional examples (Patent Documents 1 to 3) have a problem that both the visibility of food and the humidity control of the storage room cannot be improved at the same time.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a refrigerator capable of simultaneously improving both the visibility of food and the humidity control of a storage room. It is.

  Next, the outer case 7 and the inner case 11 will be described with reference to FIGS.

  FIG. 3 is an outline view of the outer case of the vegetable compartment in Embodiment 1 of the present invention, FIG. 4 is a front view of the outer case of the vegetable compartment in Embodiment 1 of the present invention, and FIG. It is a perspective view which shows the schematic structure of the cover and its periphery in Embodiment 1 of this invention.

  First, as shown in FIG. 3, the outer case 7 is provided with an inner case 11.

  The outer case 7 has a surface opened to the outside. For example, as shown in FIG. 3, the upper surface is opened. In addition, the outer case 7 is formed of a surface whose depth is in the short direction and a pair of surfaces (hereinafter, each surface of the first outer case 7) that is spaced apart from each other by a predetermined distance. A surface that is in the longitudinal direction and a pair of surfaces (hereinafter, each surface of the second outer case 7) that forms a pair at a predetermined interval so as to be substantially orthogonal to the surfaces. The bottom surface portion of the outer case 7 is formed in a substantially rectangular shape. The four surfaces of each surface of the first outer case 7 and each surface of the second outer case 7 are formed so as to be substantially orthogonal to the respective sides of the inner bottom surface of the outer case 7, thereby forming a box. A substantially rectangular parallelepiped shape is formed.

  The inner case 11 has, for example, two surfaces (hereinafter referred to as the first inner case 11) that have a smaller area than the surface that forms the short direction of the outer case 7 and that are formed in pairs at a predetermined interval. Each surface) is formed. In addition, the inner case 11 has a smaller area than the surface forming the longitudinal direction of the outer case 7 and has a predetermined interval substantially perpendicular to each surface of the first inner case 11. Two surfaces formed in pairs (hereinafter, each surface of the second inner case 11) are formed. The bottom surface of the inner case 11 is formed in a shape that is substantially rectangular. The four surfaces of the first inner case 11 and the second inner case 11 are formed so as to be substantially orthogonal to the sides of the inner bottom surface of the inner case 11 to form a box. A substantially rectangular parallelepiped shape is formed.

  The inner case 11 has a surface opened to the outside. The opened surface is covered with a lid 12 so as to seal the opened surface. For example, a packing or the like is formed at a location where the lid 12 is in contact with the inner case 11, whereby the lid 12 seals the inner case 11. A cover 13 is provided on the lid 12 so as to partially cover the lid 12. The cover 13 is formed to be slidable with respect to the lid 12.

  As shown in FIG. 4, the inner case 11 is accommodated in the outer case 7. The bottom surface of the inner case 11 is formed with a smaller area than the bottom surface of the outer case 7. The inner case is provided so as to contact the inner bottom surface of the outer case 7. Further, each of the four surfaces of the first inner case 11 and the second inner case 11 is formed with a smaller area than the first outer case 7 and the second outer case 7. ing. Further, the inner case 11 is housed so as to divide a part of the space in the outer case 7, for example, the left and right spaces, and in the outer case 7 in a direction substantially perpendicular to the inner bottom surface of the outer case 7. It is stored so as to partition the space.

  Next, as shown in FIG. 5, the lid 12 is provided with, for example, holes having a predetermined shape (hereinafter referred to as ventilation holes) in a checkered pattern at predetermined intervals. The humidity control material 14 is provided so as to close one. And the cover 13 is covered so that the humidity control material 14 whole may be covered. This cover 13 is slidable as described above. Moreover, packing etc. are formed in the location which contact | connects the cover 12 of the cover 13, for example, and the humidity control material 14 is sealed. In other words, a layer in which the lid 12, the humidity control material 14, and the cover 13 are sequentially stacked (hereinafter, a sealed structure) seals the surface opened to the outside of the inner case 11.

  Next, the humidity control material 14 will be described.

  Specifically, the main component of the humidity control material 14 is a porous material. Such a porous material is, for example, silica gel or the like, but is not limited thereto, and may be any material that repeats desorption and adsorption of moisture according to the surrounding humidity conditions. With such a humidity control material 14, the inside of the inner case 11 can be adjusted to a humidity suitable for storage of vegetables.

  The humidity control material 14 may have deodorizing and antibacterial properties as well as humidity control.

  As described above, in the refrigerator 1 configured as in the first embodiment, the humidity control material for adjusting the humidity in the inner case and the lid for sealing the opening of the inner case are provided, and the inner case is Since it can be accommodated in a part of the space in the outer case, both the visibility of the food and the humidity control of the storage room can be improved at the same time.

  Further, with such a configuration, the space in the outer case 7 can be partitioned in a direction substantially perpendicular to the inner bottom surface of the outer case 7.

  Further, with such a configuration, by storing the inner case 11 in the outer case 7, the vertical space of the outer case 7 can be used to the maximum, and the division is divided, so that the storage target is classified finely. It will be possible. Therefore, for example, as shown in FIG. 3, two plastic bottles can be placed on the front side of the outer case, and leafy vegetables can be placed inside the inner case 11. By doing so, not only the vertical space of the outer case 7 can be used to the maximum, but also the entire volume of the outer case 7 can be used to the maximum. Therefore, the vegetable compartment 500 can be used effectively and the visibility of food can be improved.

  Further, with such a configuration, the inner case 11 can be installed so as to divide the outer case 7 into left and right. Therefore, the organization of the whole vegetable room 500 can be improved. Thereby, it is possible to prevent forgetting to use vegetables.

  Further, since the sealed structure is installed in the inner case 11 with such a configuration, a substantially sealed space inside the inner case 11 can be formed. Thereby, it is possible to prevent cold air containing moisture from flowing out of the inner case 11 and to maintain high humidity inside the inner case 11. Therefore, it is possible to minimize the dryness of food and the like. And the transpiration | evaporation effect | action of vegetables etc. can also be suppressed. As a result, the freshness of vegetables and the like can be prolonged.

  Moreover, the inside case 11 can be made into sealed space by such a structure. Therefore, it is possible to relatively reduce the space that is subject to humidity control by the humidity control material 14. Thereby, since the humidity control by the humidity control material 14 can be performed efficiently, generation | occurrence | production of the dew condensation in the inner side case 11 can be prevented.

  Here, the effect by putting vegetables etc. vertically is demonstrated easily.

  Leafy vegetables and the like have the property of being able to maintain freshness more than when they are stored by placing them vertically. For this reason, in the fruit and vegetable department of grocery stores, the vegetables are stored as vertically as possible. More specifically, it is said that vertically growing vegetables and the like should be placed vertically, and the root portion should be kept down.

  Therefore, by vertically placing leafy vegetables or the like in the inner case 11, the period for maintaining their freshness can be improved.

  Moreover, although it demonstrates supposing that the outer case 7 is accommodated in the vegetable compartment 500 here, it is not limited to this. In short, it only has to be accommodated in the refrigerator 1. Therefore, for example, you may be accommodated in the refrigerator compartment 100 of the refrigerator 1.

Embodiment 2. FIG.
As described above, in the case where the humidity control material 14 controls the humidity in the inner case 11 in a sealed space where the humidity control target area is relatively small, the humidity can be efficiently controlled. Become. At this time, by providing an adjustment function for slightly opening the atmosphere of the sealed space to the outside, it becomes possible to actively adjust the humidity in the inner case 11 and the usability is further improved. In the second embodiment, items that are not particularly described are the same as those in the first embodiment, and the same reference numerals are used for the same functions and configurations.

  FIG. 6 is an enlarged perspective view showing a schematic configuration of the lid according to Embodiment 2 of the present invention. The difference from the first embodiment is that a moisture discharge port 15 is provided in the lid 12, and the cover 13 opens the moisture discharge port to the outside, shields it from the outside, or partially opens it.

  Specifically, the water discharge port 15 is, for example, a group of holes of a predetermined shape adjacent to each other on the edge side of one of the four sides of the lid 12 like a checkerboard pattern. Hole group) is formed on the edge side of one side at a predetermined interval. In FIG. 6, three such hole groups are formed on the edge side of one side. The cover 13 is slidable with respect to the inner case 11 in the front-rear direction (the direction in which the outer case 7 is pulled forward), and the cover 13 includes the moisture outlet 15 and the humidity control material 14. (Not shown here) can be sealed. That is, the moisture discharge port 15 is provided with the humidity control function in a pair with the cover 13.

  For example, a case is assumed where the inside of the inner case 11 becomes too humid and the humidity is lowered.

  First, the user of the refrigerator 1 slides the cover 13 toward the door side of the refrigerator 1. At this time, it is made to slide to the door side until the moisture discharge port 15 appears. Since the moisture outlet 15 is formed integrally with the lid 12, the moisture outlet 15 is usually covered with a cover 13. Therefore, the inside of the inner case 11 is in a state of being conditioned by the humidity adjusting material 14 while being kept at high humidity. Further, since the moisture discharge port 15 is a hole having a function as an outside air port outside the so-called inner case 11, if the moisture discharge port 15 is opened, a humid atmosphere inside the inner case 11 is generated outside the inner case 11. Will naturally move to a low humidity atmosphere. Therefore, the movement speed of such an atmosphere can be adjusted by adjusting the degree of opening of the moisture discharge port 15 with the cover 13. By moving the cover 13 in this manner, the area of the moisture outlet 15 can be actively adjusted. Therefore, the humidity inside the inner case 11 can be adjusted by the cover 13.

  Therefore, with such a configuration, the user inside the refrigerator 1 can further adjust the humidity inside the inner case 11 by manually adjusting the area of the moisture outlet 15. Thereby, suppression of the condensation which may arise when a large amount of vegetables are preserve | saved inside the inner side case 11 can be made still more efficient.

Embodiment 3 FIG.
The accessory case 16 may be provided in the outer case 7 shown in the first embodiment or the second embodiment. In Embodiment 3, items that are not particularly described are the same as those in Embodiment 1 or Embodiment 2, and the same functions and configurations are described using the same reference numerals.

  Here, the structure of the accessory case 16 will be described.

  The accessory case 16 is formed of an accessory case upper portion 16a and an accessory case lower portion 16b. The small case top 16a is formed of a box made of a substantially rectangular parallelepiped with one surface opened. The accessory case upper 16a is provided with locking means (not shown), and can be attached to and detached from the inner case 11 and the outer case 7 by the locking means. Further, the small case upper 16a has a part of one side opposite to the opened one side so as to form a so-called hole shape. The “small case upper 16a” corresponds to the “first small case” in the present invention, and the “small case lower 16b” corresponds to the “second small case” in the present invention.

  The accessory case lower 16b has a shape that can be accommodated in the accessory case upper 16a, and is a box made of a substantially rectangular parallelepiped with one surface opened. The accessory case lower 16b has a shape in which a part of one surface opposite to the opened surface is not opened.

  Then, as shown in FIG. 7, the accessory case 16 has an integrated structure by accommodating the accessory case lower 16b so as to overlap the accessory case upper 16a. It is locked so as not to be caught from the opened surface and so as to be close to the edge of the opening portion of each surface of the first inner case 11 or each surface of the second inner case 11.

  With such a configuration, the dead space above the inner case 11 can be effectively utilized.

Embodiment 4 FIG.
Further, the small case upper 16a and the small case lower 16b shown in the third embodiment are not used in an integrated manner, but may be used by providing them in different places. In the fourth embodiment, items not particularly described are the same as those in the first to third embodiments, and the same functions and configurations are described using the same reference numerals.

  FIG. 8: is a front view of the outer case of the vegetable compartment which showed the 2nd usage example of the accessory case in Embodiment 4 of this invention. FIG. 8 is a front view seen from the same direction as FIG.
