Description

Cold storage

technical field

The utility model relates to the structure of a vegetable room container of a refrigerator.

Background technique

Generally, a household refrigerator includes a vegetable compartment. Various researches have been carried out on the vegetable room so that it can preserve the stored vegetables etc. in a good way. For example, JP-A-2002-286358 (hereinafter referred to as Patent Document 1) discloses a refrigerator in which a moisture-permeable film is provided in a vegetable container in order to maintain the humidity in the vegetable compartment substantially constant.

Hereinafter, the conventional refrigerator described in patent document 1 is demonstrated using FIG. 24. FIG. Fig. 24 is a schematic cross-sectional view of main parts in the vicinity of a vegetable compartment in a conventional refrigerator.

As shown in FIG. 24 , in a conventional refrigerator, vegetable compartment 104 is provided between refrigerator compartment 102 and freezer compartment 103 of refrigerator main body 101 . Vegetable compartment 104 includes vegetable compartment container 106 drawn out by opening and closing drawer door 105 . The upper opening of the vegetable compartment container 106 is provided with a lid 108 that can be hermetically covered, and a moisture-permeable film 107 is provided on a part of the lid 108 .

Moisture-permeable membrane 107 allows moisture components to permeate to the outside of vegetable compartment container 106 through moisture-permeable membrane 107 when the humidity in vegetable compartment 104 exceeds a predetermined value. Thereby, the humidity of the vegetable compartment container 106 is maintained substantially constant, and vegetables etc. are cooled and stored in a good state.

However, in the structure of the above-mentioned conventional refrigerator, since the lid 108 of the airtight vegetable compartment container 106 is provided with the moisture-permeable film 107, the lid 108 is required.

In addition, in recent years, refrigerators in which vegetable compartment container 106 is composed of an upper container and a lower container stacked in two layers to increase the food storage capacity have become mainstream. In this case, a moisture-permeable film is provided on the bottom surface of the upper container. In this case, there is a problem that the moisture-permeable film provided on the bottom surface of the upper container is damaged by fruits and vegetables stored in the upper container.

Therefore, in order to avoid the above-mentioned problems, it is conceivable to provide the moisture-permeable film 107 on the outer peripheral wall of the vegetable compartment container 106 . In this case, the outer shape is large, and it is necessary to form an opening in a part of the outer peripheral wall of the box-shaped vegetable compartment container 106 molded with resin to attach the moisture-permeable film 107 . Generally, however, it is difficult to provide an opening for attaching the moisture-permeable membrane 107 to the outer peripheral wall of the box-shaped vegetable compartment container 106 by integral molding. Therefore, an additional process of forming an opening for mounting the moisture-permeable membrane 107 is required. As a result, there are problems such as reduction in productivity.

Utility model content

The utility model provides a refrigerator which prevents damage to a moisture-permeable film or lowers productivity and can maintain the humidity in a vegetable compartment at a predetermined value.

That is, the refrigerator of the present invention has a structure including a storage room including a vegetable compartment container including a vegetable storage section and a non-vegetable storage section separated by a partition plate provided with a moisture-permeable film.

According to this structure, a moisture-permeable membrane is attached to a partition plate, and is arrange|positioned at the position which partitions between the vegetable storage part and the non-vegetable storage part in a vegetable compartment container. Thereby, vegetables etc. will not be damaged by being placed on the upper part of a moisture-permeable membrane. In addition, since the partition plate to which the moisture-permeable membrane is attached can also be made into a plate-shaped member instead of a box-shaped container like the vegetable compartment, it can also be reduced in size. Thereby, when forming a partition plate, the opening for attaching a moisture-permeable membrane can be formed by integral molding. As a result, reduction in productivity can be prevented. Moreover, the humidity of the vegetable storage part can be maintained substantially constant by a moisture-permeable film. As a result, it is possible to provide a refrigerator that cools and preserves vegetables and the like in a good state.

<Control structure>

Next, the control structure of the refrigerator of this embodiment is demonstrated using FIG. 23. FIG.

Fig. 23 is a control block diagram of the refrigerator in this embodiment.

As shown in FIG. 23 , the control block of the refrigerator in this embodiment includes at least a refrigerator compartment temperature detection unit 78 , a vegetable compartment temperature detection unit 79 , a freezer compartment temperature detection unit 80 , a control unit 81 and the like. The refrigerating compartment temperature detecting part 78, the vegetable compartment temperature detecting part 79, and the freezing compartment temperature detecting part 80 are made of, for example, thermistors, and are respectively installed in appropriate positions of the refrigerating compartment 7, the vegetable compartment 8, and the freezing compartment 9 as storage rooms to Check the temperature. The control part 81 is comprised, for example with a microcomputer etc., and controls the whole refrigerator collectively. That is, control unit 81 is controlled by preinstalled control software based on outputs from refrigerating compartment temperature detecting unit 78 and freezing compartment temperature detecting unit 80 . Specifically, control unit 81 controls the opening and closing of refrigerator compartment damper 31 and freezer compartment damper 34 . The control unit 81 also controls the driving of the compressor 15 and the cooling fan 19 . Through these controls, the control unit 81 controls each storage room to have a set temperature.

And the control part 81 controls the operation of the vegetable compartment fan 53 incorporated in the vegetable compartment passage part 50 of the vegetable compartment 8 . Specifically, when detecting that the temperature detected by any one of the refrigerating compartment temperature detecting unit 78 and the vegetable compartment temperature detecting unit 79 is higher than the respective set temperatures for driving the vegetable compartment fan 53, the control unit 81 drives the vegetable compartment fan 53. Room fan 53. Thereby, the control part 81 controls the temperature in the storage room which comprises the vegetable compartment 8 to be set temperature.

As mentioned above, the control of the refrigerator of this embodiment is comprised.

Hereinafter, the operation|movement and effect|action of the refrigerator comprised as mentioned above are demonstrated.

First, the operation of the refrigeration cycle in the refrigerator according to the present embodiment will be described.

First, according to the temperature set in the refrigerator, according to the signal from the control part 81, the refrigerating cycle which generates cold air operates. Thereby, the cooling operation of the refrigerator is started.

When the cooling operation is started, the high-temperature and high-pressure refrigerant discharged from the compressor 15 is condensed and liquefied to some extent in a condenser (not shown) by the operation of the compressor 15 . Then, the high-temperature and high-pressure refrigerant reaches a capillary (not shown) through refrigerant pipes (not shown) arranged on the side or back of the refrigerator, or in the front range of the refrigerator. Accordingly, the high-temperature and high-pressure refrigerant is further condensed and liquefied while preventing dew condensation in the refrigerator.

Thereafter, the refrigerant is decompressed while exchanging heat with a suction pipe (not shown) leading to the compressor 15 in the capillary tube, becomes a low-temperature and low-pressure liquid refrigerant, and reaches the cooler 18 of the cooling chamber 16 . Then, the refrigerant in the cooler 18 evaporates and vaporizes. Thereby, cold air for cooling each storage room is generated in the cooling room 16 having the cooler 18 .

Next, the cooling operation of the cold air cycle in the refrigerator according to the present embodiment will be described.

First, the low-temperature cold air generated in the cooling chamber 16 is sent by the cooling fan 19 from the cooling chamber cold air delivery path 30 to the refrigerator compartment 7 and the freezer compartment 9 . The cold air supplied to refrigerator compartment 7 is supplied to vegetable compartment 8 after cooling refrigerator compartment 7 . Thereby, storage rooms, such as refrigerating room 7, vegetable room 8, and freezing room 9, are cooled to preset temperature. And the cool air after cooling each store room returns to the cooling room 16 again, and is cooled by the cooler 18 . Thereafter, the above-described operation of circulating cooling in each storage chamber by the cooling fan 19 is repeated again. At this time, the cold air supplied to each storage room is controlled and supplied by the control part 81 so that each storage room may maintain the preset temperature range. Specifically, the control unit 81 controls the operation/stop of the compressor 15 and the cooling fan 19 and the opening and closing of the refrigerating compartment damper 31 and the freezing compartment damper 34 based on the detected temperatures of the refrigerating compartment temperature detecting unit 78 and the freezing compartment temperature detecting unit 80. close. Thereby, each store room is maintained in a preset temperature range.

Next, the cooling operation of the vegetable compartment 8 of the refrigerator according to the present embodiment will be described.

First, vegetable compartment 8 is cooled by cold air after cooling refrigerator compartment 7 from refrigeration cold air return passage 33 . At this time, as shown in FIG. 11 , cold air is supplied from the vegetable cold air inlet 44 provided in the cold air return path 38 . Specifically, the cool air flows slowly from the vegetable cool air inlet 44 through the vegetable compartment passage 50 into the vegetable compartment 8 by the blowing pressure of the cooling fan 19 . The cold air that has flowed in flows in the space formed between the lower container 57 and the upper container 58 of the vegetable compartment container 55 and the inner peripheral wall of the vegetable compartment 8 . Then, vegetables, bottles, and the like stored in vegetable compartment container 55 are indirectly cooled from the outer periphery of vegetable compartment container 55 . Thereafter, the cold air that has cooled vegetable compartment 8 returns from cold air return duct 40 to cooling chamber 16 from vegetable cold air return port 46 via refrigerating cold air return passage 33 , and is further circulated.

Moreover, the refrigerator of this embodiment is provided with the vegetable compartment fan 53 in the vegetable compartment passage part 50 of the vegetable compartment 8, as shown in FIG. Therefore, when the vegetable compartment fan 53 rotates, most of the return cold air flowing through the return passage 38 is sucked into the vegetable compartment passage portion 50 from the vegetable cool air inlet 44 . Then, the sucked cold air is supplied from the air outlet 54 of the vegetable compartment fan 53 to the rear of the lower container 57 in the vegetable compartment 8 , particularly the rear of the non-vegetable storage portion 60 .

The cold air supplied to the lower container 57 of the vegetable compartment 8 is faster than the cold air flow that circulates in the space between the lower container 57 and the upper container 58 and the bottom surface and the inner peripheral wall of the vegetable compartment 8 by the blown air from the cooling fan 19. flow. Then, the cool air returns to the cooling chamber 16 through the return path 38 from the vegetable cool air return port 46 and circulates. At this time, the cold air other than the cold air returned to the cooling chamber 16 for circulation is sucked into the first passage 47a and the second vegetable cold air inlet 51 from the first vegetable cold air suction port 47 and the second vegetable cold air suction port 51 provided on the top of the vegetable compartment 8. Passage 51a. The sucked cool air is sucked into the vegetable compartment fan 53 from the upper opening of the vegetable compartment passage portion 50 communicating with the first passage 47a and the second passage 51a. Then, the cool air sucked by the vegetable compartment fan 53 is supplied to the lower container 57 in the vegetable compartment 8 again from the air outlet 54 of the vegetable compartment fan 53 . Thereby, cool air circulates while diffusing in the vegetable compartment 8 .

Next, applications of the vegetable compartment container of the present embodiment will be described in detail.

First, the lower container 57 of the vegetable compartment container 55 of the refrigerator according to the present embodiment is divided into a vegetable storage section 61 and a non-vegetable storage section 60 by a partition plate 59 . Furthermore, the upper container 58 is placed on the top opening of the vegetable storage portion 61 and the upper end of the partition plate 59 . Thereby, the vegetable compartment container 55 can be comprised by three storage parts, and foodstuffs can be divided and stored in each storage part. Specifically, for example, fruit can be efficiently stored in the upper container 58, vegetables can be stored in the vegetable storage unit 61, and beverages such as bottles (bottles) and bags (bags) can be stored in the non-vegetable storage unit 60 .

In addition, as described above, in the vegetable compartment container 55 , the moisture-permeable membrane unit 62 including the moisture-permeable membrane 622 is attached to the partition plate 59 forming the vegetable storage portion 61 . Thereby, the humidity in the vegetable storage part 61 can be maintained substantially constant (including constant), and vegetables can be cooled and stored in a good state. That is, normally, the inside of the vegetable storage section 61 is in a high-humidity state due to the moisture evaporated from the vegetables stored in the vegetable storage section 61 . However, when it becomes more than a predetermined humidity, for example, when it is more than the saturated humidity, as shown by the dotted arrow in FIG. Inside the storage unit 60 . Thereby, the inside of the vegetable storage part 61 is maintained at the humidity of 80-95% R.H., for example. As a result, vegetables and the like can be cooled and preserved in a good state.

Moreover, the moisture-permeable film 622 is arrange|positioned in the position between the vegetable storage part 61 and the non-vegetable storage part 60 in the vegetable compartment container 55. As shown in FIG. Therefore, the moisture-permeable membrane 622 is not damaged by placing vegetables and the like on top as in the prior art. In addition, the partition plate 59 to which the moisture-permeable membrane unit 62 having the moisture-permeable membrane 622 is attached can be formed of, for example, a small plate-shaped member instead of a box-like shape like the vegetable compartment container 55 . Therefore, when the partition plate 59 is molded, the opening 591 for attaching the moisture-permeable membrane unit 62 shown in FIG. 17 can be formed by integral molding. As a result, reduction in productivity of vegetable compartment container 55 and the like can be prevented.

In addition, in the present embodiment, as described above, the vegetable compartment container 55 is constituted by the lower container 57 and the upper container 58 slidably mounted on the upper portion of the lower container 57 in the front-rear direction. Furthermore, the upper container 58 is used as a lid member covering the upper part of the vegetable storage part 61 . Therefore, the upper part of the vegetable storage part 61 can be suitably covered by the upper container 58, and it can form substantially airtight (including airtight). Thereby, cold air can be prevented from penetrating into the vegetable storage part 61 . Furthermore, the humidity in the vegetable storage part 61 can be kept substantially constant (including constant), and vegetables can be favorably cooled and stored.

In addition, the moisture-permeable membrane 622 is attached to the partition plate 59 as the moisture-permeable membrane unit 62 integrally formed with the resin frame 621 . Therefore, the moisture-permeable membrane 622 itself can also be easily attached to the partition plate 59 .

In addition, the partition plate 59 is fitted with the hanging piece portions 593 a , 593 b formed at both ends of the partition plate 59 into the recess 57 a formed at the upper end of the outer peripheral wall of the lower container 57 . That is, the mounting piece portions 592 a and 592 b of the partition plate 59 are inserted into the lower container 57 along the recess 57 a provided at the upper end of the outer peripheral wall of the lower container 57 . Therefore, the partition plate 59 can be attached only by fitting in from the upper opening of the lower container 57 . In addition, the partition plate 59 is positioned and fixed in the left-right direction by fitting the hanging pieces 593a and 593b into the recess 57a. Therefore, it can prevent that the volume of the vegetable storage part 61 or the non-vegetable storage part 60 is changed by the partition plate 59 moving unexpectedly in the lower container 57. As shown in FIG. In addition, it is possible to prevent the bottles and the like stored in the non-vegetable storage unit 60 from moving every time the door 11 is opened and closed, thereby preventing the partition plate 59 from being pushed into the vegetable storage unit 61 side to degrade the vegetables and the like.

In addition, the partition plate 59 is detachably attached to the lower container 57 of the vegetable compartment container 55 . Therefore, cleaning and maintenance of the moisture-permeable membrane unit 62 are easy.

As described above, in the refrigerator according to the present embodiment, the moisture-permeable membrane 622 is provided on the partition plate 59 in a position where the moisture-permeable membrane 622 is not damaged or in a shape that does not lower productivity. Thereby, the humidity of the vegetable storage part 61 can be maintained substantially constant (including constant), and vegetables etc. can be cooled and stored in a favorable state.

Moreover, the refrigerator of this embodiment reduces the sliding of the upper container 58 which comprises the vegetable compartment container 55, and makes it easy to move. In addition, since the lower container 57 and the upper container 58 are in close contact with each other without gaps, cold air can be effectively prevented from entering the lower container 57 .

Therefore, below, the reason why the upper container 58 can be slightly moved and the reason why cold air can be prevented from entering the lower container 57 will be described more specifically.

That is, as described above, in the state where the door 11 is closed and the vegetable compartment container 55 is accommodated in the vegetable compartment 8, the protruding portion 68 provided on the upper container rail portion 63 of the upper container 58 is aligned with the lower layer container 57 provided on the lower container 57. The container rail portion 64 is accommodated in a state where the recessed portion 72 is fitted. Therefore, when the vegetable compartment container 55 is drawn out of the vegetable compartment 8 through the door 11 , the upper container 58 and the lower container 57 constituting the vegetable compartment container 55 are drawn out together with the door 11 .

Moreover, in the state where the vegetable compartment 8 is drawn out, when the user takes out the vegetables stored in the vegetable storage portion 61 in the lower container 57 or stores the vegetables in the vegetable storage portion 61, the user pushes the vegetables backward and places them on the lower layer. The upper container 58 of the container 57. Accordingly, the upper container 58 slides and moves into the vegetable compartment 8 on the lower container rail portion 64 opened on the upper surface of the lower container 57 .

At this time, as shown in FIG. 22 , the protrusion 68 provided on the upper container rail 63 of the upper container 58 straddles the recess 72 of the lower container rail 64 and contacts the straight portion 69 of the lower container rail 64 . At the same time, the linear portion 67 of the upper container rail portion 63 is also in contact with the intersection portion 71 of the lower container rail portion 64 . Therefore, the upper container 58 is supported by the lower container rail portion 64 by point contact between the protrusion portion 68 and the intersection portion 71 at two points. Thereby, the sliding resistance generated when the upper container 58 and the lower container 57 slide is reduced. As a result, the upper container 58 can be slid on the lower container rail portion 64 of the lower container 57 with relatively light force. Therefore, even if the upper container 58 is heavy due to accommodating many fruits and the like, the upper container 58 can be slid and moved with a relatively light force.

In addition, when the door 11 is closed and the vegetable compartment container 55 is stored in the vegetable compartment 8 , the protrusion 68 of the upper container rail 63 is accommodated in the recess 72 of the lower container rail 64 . At this time, the straight portion 67 of the upper container rail portion 63 and the straight portion 69 of the lower container rail portion 64 are in a state of being in contact with each other in line contact (surface contact). Therefore, the contact portion between the straight portion 67 of the upper container rail portion 63 and the straight portion 69 of the lower container rail portion 64 is in close contact with each other without gaps. Thus, it is possible to prevent the cold air from entering the vegetable compartment container 55 from the vegetable compartment fan 53 and the blower port 54 from the vegetable compartment fan 53 and the air outlet 54 into the vegetable storage portion of the lower compartment container 57 from between the lower compartment container 57 and the upper compartment container 58. Within 61. As a result, the vegetables and the like stored in the vegetable storage unit 61 can be prevented from being dried and deteriorated in advance, and can be stored in a good state with intermittent cooling.

Moreover, in addition to the structure of the above-mentioned vegetable compartment container, the refrigerator of this embodiment has various effects also in cooling a vegetable compartment. Therefore, various effects of cooling the vegetable compartment will be described below.

First, in this embodiment, a vegetable compartment fan 53 is provided in the vegetable compartment 8 . And the air outlet 54 of the vegetable compartment fan 53 is provided in the back part of the vegetable compartment 8 in the non-vegetable storage part 60 side of the vegetable compartment container 55. As shown in FIG. That is, it is configured to diffuse or/and circulate cold air in the vegetable compartment 8 to the non-vegetable storage portion 60 . Thereby, the cold air supplied by the vegetable compartment fan 53 is concentrated and circulated around the non-vegetable storage part 60 . Therefore, the bottle, bag, etc. accommodated in the non-vegetable storage part 60 can be cooled efficiently.

Usually, the heat capacity of drinks such as bottles and bags stored in the non-vegetable storage unit 60 is larger than that of vegetables, so it is difficult to cool them down. Therefore, the temperature of vegetable compartment 8 tends to rise due to storage of bottles and the like. However, according to the said structure, the temperature rise of the vegetable compartment 8 can be suppressed efficiently by cooling the non-vegetable storage part 60 directly.

Moreover, in this embodiment, the vegetable compartment fan 53 and the 1st cold vegetable air inlet 47 provided in the vegetable compartment 8 are provided in the front part of the vegetable compartment container 55 by the non-vegetable storage part 60 side. Therefore, the cool air from the vegetable compartment fan 53 to the vegetable cool air return port 46 can be more efficiently concentrated and circulated in the non-vegetable storage portion 60 . As a result, the non-vegetable storage part 60 can be cooled more effectively.

In addition, in this embodiment, in order to circulate the cool air in the vegetable compartment 8, the second vegetable cool air inlet 51 is provided in the upper part of the vegetable compartment 8 at a position substantially diagonal to the vegetable compartment fan 53 (including the diagonal position). . Therefore, the cold air supplied via the vegetable compartment fan 53 diffuses or/and circulates while passing through the bottom surface portion of the non-vegetable storage portion 60 of the vegetable compartment container 55 obliquely and vertically through the vegetable compartment 8 forward. Then, the cold air flows into the second vegetable cold air suction port 51 at the top of the vegetable compartment 8 . Thereby, cold air can be prevented from entering the vegetable compartment container 55 constituted by the lower container 57 and the upper container 58 . Also, by diffusing or/and circulating cool air over a wide range of the outer periphery of the vegetable compartment container 55, vegetables, bottles, and the like can be effectively cooled.

In addition, in the refrigerator of this embodiment, the communication path 39 is provided between the refrigerated cold air going passage 32 and the refrigerated cold air return path 33 . And, when the vegetable compartment fan 53 rotates, the low temperature and fresh cold air in the refrigerated cold air going passage 32 is mixed into the refrigerated cold air returning passage 33 by its suction force. The mixed cool air is supplied into vegetable compartment 8 from vegetable cool air inlet 44 via return passage 38 . That is, by the rotation of vegetable compartment fan 53 , low-temperature and fresh cool air is mixed into the cold air after cooling refrigerator compartment 7 , and vegetable compartment 8 is cooled by the cooled cold air. Thereby, vegetable compartment 8 can be cooled efficiently. Specifically, even when a lot of vegetables are temporarily stored, or the cooling load conditions such as bottles are poor, the vegetable compartment 8 can be reliably cooled. In addition, the amount of low-temperature and fresh cold air taken in through the communication passage 39 can be increased by increasing the rotation speed of the vegetable compartment fan 53 . Therefore, even when storing a large amount of normal-temperature bottles and the like with a large heat capacity in summer or the like, it can be reliably cooled. In addition, since the vegetable compartment 8 is reliably cooled according to the above, generation of dew condensation due to cold radiation from the cooling compartment 16 can be efficiently suppressed. As a result, vegetables can be cooled and stored in a better state.

Moreover, in this embodiment, the refrigerator compartment damper 31 is opened by the output from the refrigerator compartment temperature detection part 78, and the refrigerator compartment 7 and the vegetable compartment 8 are cooled. At this time, the vegetable compartment fan 53 is operated to diffuse or/and circulate cold air in the vegetable compartment 8 . Furthermore, it is comprised so that the operation|movement of the vegetable compartment fan 53 may be controlled also based on the detected temperature of the vegetable compartment temperature detection part 79 provided in the vegetable compartment 8. As shown in FIG. Therefore, even when the temperature of refrigerator compartment 7 is high and the cooling operation is not performed, when the temperature of vegetable compartment 8 becomes higher than the set temperature, vegetable compartment fan 53 starts to rotate. Then, the cold air is diffused or/and circulated in the vegetable compartment 8 . Thus, when the temperature of vegetable compartment 8 is high and dew condensation is likely to occur due to a large temperature difference due to cold radiation from cooling chamber 16, vegetable compartment fan 53 rotates to eliminate this situation. As a result, generation of dew condensation in vegetable compartment 8 can be effectively prevented.

In addition, in this embodiment, when the temperature of the vegetable compartment 8 is higher than the second set temperature which is set to a temperature slightly higher than the set temperature regardless of the rotation of the vegetable compartment fan 53, the vegetable compartment fan is raised. The rotation speed of 53 enhances the diffusion or/and circulation of cold air. Furthermore, the intake and mixing amount of low-temperature and fresh cold air into vegetable compartment 8 is increased. Thereby, the vegetable compartment 8 can be reliably cooled, and especially the cooling shortage in summer etc. can be eliminated. As a result, favorable cold storage of vegetables etc. can be realized more reliably, and the refrigerator with high reliability can be realized.

In addition, the structure demonstrated in the said embodiment was shown as an example which implements this invention. Therefore, it is needless to say that various modifications can be made within the scope of achieving the object of the present invention.

That is, in the above-mentioned embodiment, the example in which the moisture-permeable membrane 622 is formed by laminating silicon thin films and hydrophilic nylon fibers has been described, but the present invention is not limited thereto. For example, the material and structure of the moisture-permeable membrane may be arbitrary as long as it is a moisture-permeable membrane that allows the moisture content to permeate to maintain a substantially stable humidity when the humidity in the vegetable storage portion 61 exceeds a predetermined value.

In addition, in the above-mentioned embodiment, the structure in which the lower container 57 of the vegetable compartment container 55 is partitioned left and right by the partition plate 59 and the non-vegetable storage part 60 is provided on either side has been described as an example, but it is not limited to this. For example, the lower container 57 may be partitioned in the front-rear direction by the partition plate 59 , and the non-vegetable storage portion 60 may be provided in the front portion of the lower container 57 . Thereby, the same effect can be obtained, and the degree of freedom of design can be improved.

In addition, in the above-mentioned embodiment, the structure in which the moisture-permeable membrane 622 is incorporated in the moisture-permeable membrane unit 62 and attached to the partition plate 59 has been described as an example, but it is not limited thereto. For example, a structure in which the moisture-permeable membrane 622 is directly attached to the opening 591 of the partition plate 59 may be employed. Thereby, component parts can be reduced.

Moreover, in the said embodiment, the structure which partitioned the lower container 57 into the vegetable storage part 61 and the non-vegetable storage part 60 by the partition plate 59 was demonstrated as an example, but it is not limited to this. For example, the lower container 57 may be constituted by only the vegetable storage portion 61 . In this case, recesses 57 a for attaching the partition plate 59 are formed on the left and right side walls of the lower container 57 . Thereby, the partition plate 59 provided with the moisture-permeable membrane 622 can be easily attached to the lower container 57 . Furthermore, since there is no need to provide an opening for attaching a moisture-permeable membrane by integral molding with the lower container 57, productivity will not be lowered.

Moreover, although it did not demonstrate in the said embodiment, you may provide the movement prevention member 60a in the non-vegetable storage part 60 like FIG.15 and FIG.16. Thereby, storage places such as bottles and bags are partitioned off. Furthermore, it is possible to prevent the stored bottles, bags, etc. from being turned upside down or moved due to the opening and closing of the door 11 .

In addition, although not described in the above-mentioned embodiment, a plurality of holes may be provided in the outer peripheral wall of the non-vegetable storage portion 60 of the lower container 57 other than those partitioned by the partition plate 59 . Thereby, the bottle etc. accommodated in the non-vegetable storage part 60 can be cooled more effectively.

As described above, the refrigerator of the present utility model has the following structure: it has a storage room including at least a vegetable compartment container, and the vegetable compartment container includes a vegetable storage part and a non-vegetable storage part separated by a partition plate, and the partition plate is set Has a moisture-permeable membrane.

According to this structure, a moisture-permeable membrane is attached to a partition plate, and is arrange|positioned at the position which partitions between the vegetable storage part and the non-vegetable storage part in a vegetable compartment container. Thereby, vegetables etc. will not be damaged by being placed on the upper part of a moisture-permeable membrane. In addition, since the partition plate to which the moisture-permeable membrane is attached can also be made into a plate-shaped member instead of a box-shaped container like the vegetable compartment, it can also be reduced in size. Thereby, when forming a partition plate, the opening for attaching a moisture-permeable membrane can be formed by integral molding. As a result, reduction in productivity can be prevented. Moreover, the humidity of the vegetable storage part can be maintained substantially constant by a moisture-permeable film. As a result, it is possible to provide a refrigerator that cools and preserves vegetables and the like in a good state.

Moreover, the refrigerator of this invention may further include the cover member which covers the upper part of a vegetable storage part. Thereby, cold air can be prevented effectively from invading into the vegetable storage part.

According to this structure, the vegetable compartment container has three storage parts, the storage part of the vegetable storage part and the non-vegetable storage part in the lower container, and the storage part of the upper container. Therefore, non-vegetable ingredients such as vegetables, fruits, and bottles can be divided and stored efficiently. Furthermore, the upper container is used as the cover member covering the upper part of the vegetable storage part. Thereby, intrusion of cold air can be effectively prevented, and vegetables can be favorably cooled and stored.

In addition, in the refrigerator of the present invention, the moisture-permeable membrane and the resin frame may be integrally formed to form a moisture-permeable membrane unit, and the moisture-permeable membrane unit may be provided on the partition plate.

Thereby, it can be attached only by fitting the partition plate into the lower container from the upper opening of the lower container. Furthermore, the partition plate can be easily positioned and fixed by fitting the hanging piece portion into the recess. Accordingly, it is possible to prevent the volume of the vegetable storage section or the non-vegetable storage section from being changed due to the partition plate accidentally moving in the lower container.

In addition, in the refrigerator of the present utility model, the upper container may include an upper container rail portion, the lower portion of the upper container rail portion is formed by a straight line portion, and a protrusion is provided in front of the upper container rail portion, and the lower container is provided with a The lower container rail portion supporting the upper container rail portion, the lower container rail portion has a straight portion, an inclined portion inclined downward, and an intersection between the straight portion and the inclined portion, and the intersection portion is disposed behind the lower container rail portion.

According to this configuration, when the upper container is slid relative to the lower container, the upper container comes into contact with two points at the intersection of the protrusion of the upper container rail and the intersection of the lower container rail. Therefore, the sliding resistance between the upper container and the lower container can be reduced. Thereby, the upper container can be moved with light force. In addition, when storing the upper container and the lower container in the vegetable compartment as a storage room, the linear portion of the upper container rail portion and the linear portion of the lower container rail portion are in line contact (surface contact). Therefore, no gap is formed between the upper container and the lower container. Thereby, cold air circulating in the storage room can be prevented from entering the vegetable storage portion of the lower container. As a result, vegetables and the like stored in the vegetable storage portion of the lower container can be favorably cooled and stored without deteriorating due to drying.

Moreover, the refrigerator of this invention may have the recessed part which accommodates the protrusion part of the upper container rail part in the front side of the linear part of the lower container rail part of a lower container.
