Description

Refrigerator and storage box in refrigerator

The present invention relates to a refrigerator and a storage box provided in the refrigerator.

Most of the fruits and vegetables such as vegetables contain more than 90% of water. It is generally believed that if about 5% of the water is lost, the value of the commodity is lost. The water loss caused by evaporation is the cause of the decrease in the quality of fruits and vegetables such as weight loss and wilting. Therefore, it is important that the fruits and vegetables such as vegetables suppress evaporation to maintain freshness. Here, the evaporation of vegetables is more intense, and is suppressed at low temperatures. Further, in suppressing the evaporation action, it is known that the control humidity is effective in addition to the temperature. Moreover, the evaporation system and the surface of the fruits and vegetables are roughly proportional to the water vapor pressure difference of the outside air. Therefore, in order to maintain the freshness of the fruits and vegetables, the low temperature storage room is set to a high humidity environment, and in the ring It is better to contain (save) fruits and vegetables under the environment.

However, on the other hand, in order to maintain the freshness of fruits and vegetables such as vegetables, it is also necessary to suppress condensation. For example, when the airflow enters the storage room due to opening or closing of the door, or the humidity in the storage compartment rises rapidly due to the input of food into the storage compartment, dew condensation may occur in the storage compartment. At this time, the dew condensation drops, and when it comes into contact with food, it promotes the growth of bacteria and mildew due to dew condensation, leading to the corruption of fruits and vegetables.

In this case, a refrigerator is provided, for example, "the vegetable storage portion disposed in the vegetable compartment has a plurality of storage blocks, and the storage compartments are substantially sealed by the compartments" (see Patent Document 1). Further, Patent Document 1 discloses a configuration in which a humidity control means for adjusting the humidity between adjacent storage blocks is provided in a partition plate that partitions a plurality of storage blocks, in addition to the configuration of the refrigerator.

Here, the number of boxes installed in each storage room may be one. However, from the viewpoint of the capacity of the entire refrigerator, two or more cases may be used in the case where the finishing property is improved.

A cooling device that supplies cold air to each storage compartment has a compressor 2, a cooler 3, and a blower fan 4. The compressor 2 and the cooler 3 are connected by a refrigerant pipe in the order of the compressor 2, the cooler 3, and the decompression device (not shown). The piping that connects the pressure reducing device and the suction side of the compressor 2 is disposed, for example, on the side surface of the refrigerator 1 and functions as an evaporator. That is, the refrigeration cycle apparatus is constituted by the compressor 2, the cooler 3, the decompression device (not shown), and the like.

The components constituting the cooling device, the compressor 2, the cooler 3, and the blower fan 4 are disposed on the back surface of the refrigerator 1. Specifically, the compressor 2 is provided at a lower portion of the rear surface portion of the refrigerator 1. The cooler 3 and the blower fan 4 are provided in the air passage 5 formed in the back part of the refrigerator 1.

Etc., the temperature of each storage compartment becomes the preset temperature.

Next, details of the vegetable compartment 500 of the refrigerator 1 according to the first embodiment will be described.

Fig. 3 is a cross-sectional view showing the vegetable compartment according to the first embodiment of the present invention as seen from the side surface side. Further, Fig. 4 is a cross-sectional view of the vegetable compartment as viewed from above. In addition, the third drawing is a cross-sectional view seen from the same direction as the second drawing, and the opening of the vegetable compartment 500 (that is, the position of the door 11) is indicated on the left side of the paper. Moreover, the fourth drawing shows the opening of the vegetable compartment 500 (that is, the position of the door 11) on the lower side of the paper surface.

The storage case 501 provided in the vegetable compartment 500 has two cases (the lower case 7 and the upper case 8). The lower case 7 is open at the upper portion and is connected to the door 11 (also formed integrally with the door 11). That is, the lower case 7 is pulled out in conjunction with the door 11. Further, the lower casing 7 is provided with a partition 10, and the inside is divided into two regions (a front region 7a and a rear region 7b).

The upper case 8 is open at the upper portion and is disposed above the lower case 7 so as to overlap. More specifically, the upper box 8 is configured to cover the lower box 7 A part of the opening of the portion region 7b. In Figs. 3 and 4, the upper case 8 covers the range excluding the opening of the rear portion 7b.

Further, the side wall of the lower case 7 extends beyond the bottom surface of the upper case 8, and the side wall is divided into a front portion 7a of the area where the opening is not covered by the upper case 8. Thereby, even if it is the food of the height which the lower case 7 cannot accommodate, this food can be accommodated in the front area|region 7a. In this way, since the state of the food of a high height such as a beverage bottle can be erected, the convenience is improved.

The opening portions of the lower case 7 and the upper case 8 are covered by the cover 9. More specifically, in the lower portion of the first embodiment, the internal space of the case 7 is divided by the partition 10, and the opening of the rear portion 7b of the lower case 7 (described in more detail, the upper portion of the opening is not included) The range covered by 8) and the opening of the upper case 8 are covered by the cover 9. Thereby, the inner space of the rear portion 7b and the upper casing 8 of the lower casing 7 can be made into a space having a high degree of sealing. Further, the "space having a high degree of airtightness" as used in the first embodiment means that the cover 9 covers the opening of the rear region 7b and the opening of the upper casing 8 so that the air does not pass from the rear region 7b of the lower casing 7. The state in which the upper casing 8 flows by an air passage other than the air passage 13 to be described later.

The cover 9 has a double structure formed by the upper panel 9a and the lower panel 9b, and an air layer is formed between the upper panel 9a and the lower panel 9b. In other words, the inside of the cover 9 (between the upper panel 9a and the lower panel 9b) has a hollow double structure. Further, a vent port 12a and a vent port 12b that communicate with the internal space of the double structure are formed on the cover 9. The vent opening 12a is formed in the upper panel 9a, and connects the "vegetable room 500 which becomes the rear part area 7b of the lower stage tank 7 and the upper stage tank 8" and the "double structure internal space". Again The air port 12b is formed in the lower panel 9b, and "the space in the rear region 7b and the upper casing 8 of the lower casing 7" communicates with the "double structure internal space". In other words, the "double-structured internal space" is such that "the vegetable compartment 500 which becomes the rear section 7b and the upper compartment 8" and the "lower compartment 7 rear area 7b and the space in the upper compartment 8" are connected. Wind road 13. Further, the vent port 12b of the first embodiment is constituted by the first vent port 12b1 and the second vent port 12b2 that communicate with the rear region 7b of the lower case 7. In the following description, the first vent port 12b1 and the second vent port 12b2 are not necessarily described differently, and the vent port 12b is referred to as no difference.

Here, the vent hole 12a corresponds to the external vent port of the present invention, and the vent port 12b corresponds to the internal vent port of the present invention.

As described above, in the refrigerator 1 configured as described in the first embodiment, since the opening portion of the rear region 7b of the lower casing 7 and the opening portion of the upper casing 8 are covered by the cover 9, the rear portion 7b of the lower casing 7 can be The opening and the internal space in the upper casing 8 are spaces having a high degree of sealing. Therefore, it is possible to prevent the cold air containing moisture from excessively flowing out from the rear region 7b and the upper casing 8 of the lower casing 7, and to maintain the high humidity in the rear region 7b and the upper casing 8 of the lower casing 7. Therefore, the dryness of the food contained in the rear region 7b and the upper casing 8 of the lower casing 7 can be minimized, and the evapotranspiration of these foods can be suppressed.

Further, in the refrigerator 1 configured as described in the first embodiment, the air vents 12a and 12b and the air passage 13 formed in the cover 9 can be used to lower the air in the rear region 7b and the upper casing 8 of the lower casing 7 The rear portion 7b of the tank 7 and the vegetable compartment 500 outside the upper tank 8 are taken in and out. So in the lower box 7 The air in the rear region 7b and the upper casing 8 is excessively high in humidity, and the air passes through the vents 12a and 12b and the air passage 13 to the vegetables in the rear region 7b and the upper casing 8 in the lower casing 7 The chamber 500 is discharged, and condensation can be suppressed from occurring due to an excessive rise in humidity in the rear region 7b of the lower casing 7 and the upper casing 8. Further, the humidity in the rear region 7b and the upper casing 8 of the lower tank 7 can be adjusted to a predetermined humidity in accordance with the opening amount (opening size) of the vents 12a and 12b.

Further, in the refrigerator 1 configured as described in the first embodiment, cold air containing moisture (that is, cold air discharged from the rear region 7b of the lower casing 7 and the upper casing 8) can be retained in the air passage 13. The moisture is kept in the wind path 13. Therefore, in the case where the humidity in the rear region 7b and the upper casing 8 of the lower tank 7 is lowered, the cold air containing moisture moves from the air passage 13 to the rear region 7b and the upper casing 8 of the lower casing 7, and the lower casing 7 can be made. The humidity in the rear portion 7b and the upper tank 8 rises.

In this manner, excess air can be discharged and moisturized by the air passage 13 and the vents 12a and 12b having the double structure of the cover 9, and the rear portion 7b and the upper box 8 of the lower box 7 can be held in an appropriate position. Store food in a humid environment.

Further, by making the lid 9 a double structure, the temperature distribution in the rear region 7b and the upper casing 8 of the lower casing 7 can be made uniform by the heat insulating effect of the air layer of the air passage 13. Therefore, deterioration of the food caused by temperature fluctuations in the rear region 7b and the upper casing 8 of the lower casing 7 can be prevented.

In addition, the refrigerator 1 of the first embodiment is a return air passage 5a for the refrigerating compartment passing through the top surface of the vegetable compartment 500 by the return air of the refrigerating compartment 100. Since it is circulated and cooled, the upper panel 9a and the lower panel 9b of the cover 9 have a lower temperature of the upper panel 9a than the lower panel 9b by radiant cooling from the top surface. Therefore, in the case where condensation occurs on the air passage 13, the dew condensation water adheres to the side of the upper panel 9a. Therefore, by the lower panel 9b provided on the lower side than the upper panel 9a, it is possible to prevent the dew condensation water from falling to the rear region 7b and the upper casing 8 of the lower casing 7. Thereby, it is possible to prevent contact of the food with dew condensation water which is one of the causes of food spoilage.

Further, in the refrigerator 1 configured as described in the first embodiment, the storage case 501 is constituted by two cases (the lower case 7 and the upper case 8), and the cover 9 covers the both cases (the lower case 7 and the upper case) 8) The opening. Further, the vent port 12b has a first vent port 12b1 that communicates with the lower case box 7 and a second vent port 12b2 that communicates with the upper case box 8. In other words, the lower tank 7 and the upper tank 8 communicate with each other via the first vent 12b1, the air passage 13, and the second vent 12b2. Therefore, the upper case 8 and the lower case 7 are free to enter and exit the air. Therefore, for example, when one of the cases has a low humidity, the moisture containing the moisture flows in from the other side, and the humidity in the two cases becomes balanced, and the humidity in the two cases can be adjusted to each other.

Further, in the first embodiment, since the lower casing 7 is divided into the front region 7a and the rear region 7b by the partition plate 10, the cover 9 covers the opening of the rear region 7b of the opening of the lower casing 7. That is, the space that communicates with the upper case 8 becomes the rear area 7b of the lower case 7.

Further, in the first embodiment, by forming the vent hole 12a and the vent port 12b at, for example, the following positions, dew condensation on the rear region 7b and the upper casing 8 of the lower casing 7 can be further suppressed. In detail, as shown above, the vegetable compartment 500 is passed through the vegetable compartment 500 by the return air of the refrigerating compartment 100. The refrigerating compartment on the top surface is circulated by the return air passage 5a and is cooled. Further, the vegetable compartment 500 is also cooled by the cold air blown from the cold air outlet 5c formed on the back side (see FIG. 3). Therefore, the temperature of the top side of the vegetable compartment 500 is lower than that of the bottom side, and the temperature of the back side is lower than that of the door 11 side. Therefore, by forming the vent hole 12b closer to the back side than the vent hole 12a, the vent port 12b can be disposed at a position lower than the vent port 12a. By arranging the vent holes 12a and 12b at such a position, the air containing the moisture from the food in the rear region 7b and the upper casing 8 of the lower casing 7 is disposed on the back side of the lower temperature by the vent hole 12b. It is cooled and becomes high humidity air. Further, the vicinity of the vent hole 12a communicates with the air having a low humidity outside the rear portion 7b of the lower casing 7 and the upper portion of the upper casing 8. Since the temperature is higher than the vent 12b, the humidity is always higher than the air near the vent 12b. low. Therefore, by arranging the vent ports 12a and 12b in accordance with the temperature distribution, the moisture contained in the air in the vicinity of the vent port 12b is easily moved to the vent port 12a side in the air path 13, because it is easy to move from the vent port 12a. Since the outer side is discharged, condensation on the rear region 7b and the upper casing 8 of the lower casing 7 can be further suppressed.

Second embodiment

As described above, the set humidity in the rear region 7b and the upper tank 8 of the lower tank 7 differs depending on the opening amount of the vents 12a and 12b. Therefore, by providing an adjusting device for adjusting the opening amount (in other words, the opening ratio) of the vent hole 12a, the set humidity in the rear region 7b and the upper casing 8 of the lower casing 7 can be changed, and the usability is further improved. In addition, in the second embodiment, the items that are not described in detail are the same as in the first embodiment. Function or composition, using the same symbolic description.

Fig. 5 is a cross-sectional view showing the vegetable compartment according to the second embodiment of the present invention as seen from the side surface side. This fifth drawing is a cross-sectional view seen from the same direction as that of Fig. 3, and shows the opening of the vegetable compartment 500 (i.e., the position of the door 11) on the left side of the paper.

As shown in Fig. 5, the movable cover 14 is provided on the upper panel 9a of the cover 9. The movable cover 14 is slidable, for example, on the cover 9, and the aperture ratio of the vent 12a can be changed by the position of the movable cover 14.

Here, the sliding mechanism of the movable cover 14 and the movable cover 14 corresponds to the aperture ratio adjusting device of the present invention.

By providing the movable cover 14 in this manner, the degree of sealing in the rear region 7b and the upper casing 8 of the lower casing 7 can be changed in accordance with the amount or type of food to be stored. For example, when a large amount of food is put into the rear region 7b and the upper casing 8 of the lower casing 7, the movable cover 14 is moved, and the opening ratio of the vent 12a is increased, whereby the rear portion 7b of the lower casing 7 can be discharged. And excess moisture in the upper tank 8 to suppress condensation. Further, for example, when the amount of food stored in the rear region 7b and the upper casing 8 of the lower casing 7 is small, the movable cover 14 is moved, and the opening ratio of the vent opening 12a is reduced (for example, closed). The moisture can be prevented from flowing out from the rear region 7b and the upper tank 8 of the lower tank 7, and the drying of the food can be suppressed. That is, by moving the movable cover 14 and adjusting the aperture ratio of the vent opening 12a, an optimum storage environment can be realized in accordance with the amount or type of the food.

Further, in the second embodiment, the vent hole 12a is disposed in front of the cover 9, and the movable cover 14 is slid rearward of the vent hole 12a. borrow According to this configuration, when the door 11 is opened and the storage case 501 is pulled out, since the movable cover 14 enters the viewing angle of the user, the adjustment of the aperture ratio of the vent hole 12a is facilitated, and the usability is improved.

Third embodiment

The deodorant material may be provided in the vegetable compartment 500 shown in the first embodiment or the first embodiment. In the third embodiment, the items that are not specifically described are the same as in the first embodiment or the second embodiment, and the same functions and configurations are denoted by the same reference numerals.

Fig. 6 is a cross-sectional view showing the vegetable compartment according to the third embodiment of the present invention as seen from the side surface side. Fig. 6 is a cross-sectional view seen from the same direction as Fig. 3, showing the opening of the vegetable compartment 500 (i.e., the position of the door 11) on the left side of the paper.

In the refrigerator 1 of the third embodiment, the deodorizing material 15 is placed in the vegetable compartment 500. By providing the deodorizing material 15 in the vegetable compartment 500, it is possible to prevent the malodor from spreading or remaining in the vegetable compartment 500, and to prevent the odor from moving to other foods.

In particular, as shown in Fig. 6, by providing the deodorizing material 15 in the air passage 13, the deodorizing effect can be obtained more efficiently. This is because the cold air in the rear portion 7b and the upper tank 8 of the lower tank 7 passes through the air passage 13 and can be efficiently deodorized. Further, the installation of the deodorizing material 15 is not limited to the air passage 13, and may of course be provided in at least one of the upper casing 8 and the lower casing 7.

Fourth embodiment

Moreover, the humidity control material may be provided in the vegetable compartment 500 shown in the first embodiment to the third embodiment. Further, in the fourth embodiment, there is no special The items that are not described are the same as in the first embodiment to the third embodiment, and the same functions and configurations are denoted by the same reference numerals.

Fig. 7 is a cross-sectional view of the vegetable compartment according to the fourth embodiment of the present invention as seen from the side surface side. This seventh drawing is a cross-sectional view seen from the same direction as that of Fig. 3, and shows the opening of the vegetable compartment 500 (i.e., the position of the door 11) on the left side of the paper.

In the refrigerator 1 of the fourth embodiment, the humidity control material 16 is installed in the air passage 13. The humidity-conditioning material 16 absorbs moisture when the humidity is higher than a predetermined humidity according to its characteristics, and releases moisture when the humidity is lower than a predetermined humidity. Thereby, it is easy to hold the inside of the lower section 7b and the upper case 8 of the lower case 7 at a fixed humidity. Further, the installation of the humidity control material 16 is not limited to the air passage 13, and may of course be provided in at least one of the upper casing 8 and the lower casing 7.

In the first embodiment to the fourth embodiment, an example of the present invention will be described, but the configuration described in the first embodiment to the fourth embodiment is not limited.

For example, as shown in Figs. 8 and 9, it is also possible to form a structure in which one part of the cover 9 has a double structure. Further, in Figs. 8 and 9, the area of the lower panel 9b is made smaller than that of the upper panel 9a, and the rear side of the lid 9 has a double structure. By making the low temperature portion of the vegetable compartment 500 which is easily dew condensation, a double structure is obtained, and the same effect as the case where the lid 9 is completely doubled can be obtained.

In addition, in the first embodiment to the fourth embodiment, the inside of the lower case 7 is divided into two regions by the partition plate 10, but the number of divisions inside is arbitrary. For example, of course, the inside of the lower case 7 may be divided into three or more regions, or the inside of the lower case 7 may not be divided. Also, in the lower box 7 In the case where the inside is divided into a plurality of regions, it is of course possible to cover the opening portion of the entire region with the cover 9. In other words, the region in which the opening portion is not covered in the front region 7a as in the first embodiment to the fourth embodiment is not necessarily required in the present invention.

Further, in a case where an area where the opening portion is not covered as in the front portion 7a is not formed (that is, a case where the storage height cannot be accommodated in the area of the food in one case), the lower case 7 and the upper case can also be formed. The overlapping direction of 8 is set to, for example, the front-back direction or the left-right direction. In other words, the opening portions of the lower case 7 and the upper case 8 may be formed on the front side or the side surface, and the opening portion may be covered by the cover 9, and the lower case 7 and the upper case 8 may be spaces having a high degree of sealing.

In the above-described first to fourth embodiments, the storage case 501 is configured by two cases (the lower case 7 and the upper case 8). However, the number of the cases constituting the storage case 501 (that is, the number of cases) The number of boxes that overlap in 500 is arbitrary. For example, a configuration in which three or more cases are overlapped and the openings of the cases are covered with a cover 9 may be employed. In this case, the vent hole 12b may be formed as a plurality of vent holes so as to communicate with the respective casings. Further, of course, one case may be provided in the vegetable compartment 500, and the cover 9 may cover the opening of the case.

Further, the positions or the number of formations of the vent holes 12a and 12b shown in the above-described first to fourth embodiments are completely exemplified. For example, the vent hole 12a may be provided at the center portion.

In the above-described first to fourth embodiments, an example in which the case in which the opening is covered by the cover 9 is provided in the vegetable compartment 500 is described. However, as long as there is a storage room for storing food requiring humidity adjustment, Covered by cover 9 A case in which the opening of the cover is provided is provided in the storage compartment. Further, in the above-described first to fourth embodiments, the present invention has been described by taking a refrigerator having a plurality of storage rooms as an example. However, the present invention may of course be practiced in a refrigerator having only one storage room (for example, a vegetable compartment).
