Description

  The present invention relates to a refrigerator in which a storage container having a relatively large capacity is disposed in a refrigeration chamber at the top of a main body, and more particularly, to an apparatus that improves the visual impression of the storage container portion.

  Large-capacity refrigerators for home use have been commercialized as refrigerators with many doors in each storage room as well as diversified cooling storage temperatures to meet various user needs. Top freezer type with room placed at the top, middle freezer type with freezer room between the upper refrigerator room and lower vegetable room, bottom freezer type with freezer room at the bottom, below the upper refrigerator room Various types have been commercialized, such as a type in which a vertically long freezer compartment and a vegetable compartment are juxtaposed, and a side-by-side type in which a freezer compartment and a refrigerator compartment are juxtaposed on the left and right.

  In such a product environment, in recent years, in consideration of usability, a refrigerator room that is frequently used and has the largest storage capacity is installed at the top, a vegetable room below it, and a freezer room at the bottom. The type has become mainstream, and furthermore, a relatively small-capacity ice making room, a temperature switching room, etc. are arranged between the vegetable room and the freezing room to improve usability, for example, described in Patent Document 1 There are many forms. In addition, a configuration in which the relatively small-capacity ice making chamber, temperature switching chamber, and the like are disposed between the refrigerator compartment and the middle vegetable compartment has been commercialized.

On the other hand, in refrigerators equipped with dedicated refrigerators for freezing and refrigeration, which have been widely used in the market in recent years, the evaporation temperature of the refrigeration cooler is higher than that of the type cooled by a single cooler. In addition, by reducing the temperature difference from stored foods, the amount of frost is reduced to increase the humidity in the storage space, and by improving the freshness function by precise temperature control, vegetables and fish The necessity of storing foods such as meat by classification is decreasing. In addition, since the capacity of refrigerators has been increasing in recent years, it has become possible to secure an independent large storage space in the refrigeration room. A refrigerator form in which a vegetable container partitioned and formed by a ceiling plate is disposed in a lower part of the refrigerator compartment, and a refrigerated storage space that is cooled to a freezing temperature via a heat insulating partition wall is arranged below the refrigerator compartment. Has been commercialized.

  However, as in the case of the recently commercialized refrigerator, when a vegetable container is disposed in the refrigerator compartment, it actually looks as though it has a storage capacity equivalent to the independent dedicated door type. Therefore, there is a problem that gives the user the impression that the storage capacity is small.

  This is because the inner box that forms the refrigerator compartment is made by vacuum molding a white synthetic resin material, while the color of interior parts such as shelves and containers installed in the refrigerator compartment is reduced. Regardless of the size of the parts, it is a transparent resin or a colored transparent body in which a transparent resin material is colored blue or green.For example, when the installed container is viewed from the front side, Since the thickness of the side wall and bottom wall part extending rearward can be seen through, the color tone of this part is strong and dark, and the outline of the container is emphasized. As a result, the width of the container is given to the user. It is because it ends. In addition, since the container itself is a transparent body including coloring, and the difference in material thickness and the presence of the reinforcing rib can be clearly seen, the user has given a mixed impression when viewed from the front.

  The present invention has been made in consideration of the above points, and a storage container having a relatively large capacity such as a vegetable storage container is installed in the refrigeration room to improve food storage efficiency and usability, and in the refrigeration room. An object of the present invention is to provide a refrigerator capable of visually providing a sense of spaciousness, cleanliness, and cleanliness by making an installed storage container inconspicuous in appearance.

  In order to solve the above-mentioned problems, the refrigerator according to the present invention has a refrigerator compartment disposed in the upper part of the refrigerator body, the front opening thereof is closed by a rotary door, and a heat insulating partition wall is provided below the refrigerator compartment. A freezer storage space such as a drawer door type freezing room or other storage room, and a plurality of shelves made of a transparent or colored transparent body are installed in the upper part of the refrigerating room, and the lower part of the shelf A storage container made of an opaque body is installed in the lower space in the refrigerator compartment.

  According to the configuration of the present invention, not only can each storage room be placed at a convenient height and position to increase the volume and space efficiency, but also the storage container installed in the refrigerator compartment can be shown large and wide. In addition, since the shade of color and the thickness of the material are not seen through, a clean appearance can be obtained.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. 1 is a front view of the whole, FIG. 2 is a longitudinal sectional view thereof, and FIG. 3 is a perspective view of the refrigerator main body (1) with each storage chamber door removed. The refrigerator main body (1) has an outer box (2) and an inner box (3). A foam insulation (4) is filled in between to form a heat insulation box, and the inside of the storage chamber is divided into an upper refrigerator compartment (6) and a lower frozen storage space (7) by a heat insulating partition wall (5). It is partitioned.

  The front opening of the refrigerator compartment (6) is closed by double doors (8) and (8 '), and the interior upper part is a refrigerator compartment (9) provided with a plurality of mounting shelves (9). 10), and the lower part is partitioned by a ceiling plate (12) that also serves as a mounting shelf made of transparent resin, so that an independent space is formed, and a drawer-type vegetable container (13) is placed inside the vegetable room. (11). Furthermore, at the lowermost part in the refrigerator compartment (6), a cryogenic container (15a) that cools the room to about 0 to -3 ° C through a partition bottom plate (14) that similarly forms the bottom of the vegetable compartment (11). The cold room (15) and accessory case (16) provided with a compartment are arranged as a drawer type.

  The said vegetable container (13) is arrange | positioned over the full width dimension of the inner box (3) which forms the refrigerator compartment (6), toward the back from a low front wall and front part. It is a container with an open upper surface composed of a peripheral wall that rises in an arc shape, and is configured to be slidable in the front-rear direction by slide rails (not shown) provided on both side walls of the inner box (3) in the front-rear direction. Yes.

  And when the said vegetable container (13) is accommodated and installed in the predetermined position in a refrigerator compartment (6), an upper surface is obstruct | occluded by the said ceiling board (12) arrange | positioned on the upper surface, The said vegetable container (13 ) And the front edge of the ceiling panel (12) form an opening. In addition, you may make it close the opening part of this vegetable compartment (11) so that opening and closing is possible by the cover body pivotally supported by the said ceiling board (12).

  For the frozen storage space (7), an ice making chamber (19) provided with a relatively small volume automatic ice making device directly below the heat insulating partition wall (5), and a relatively small volume cooling storage chamber, for example, A temperature switching chamber (20) that can be cooled to a freezing temperature such as a soft freezing temperature zone of −18 ° C. or −9 ° C. is divided into left and right, and is placed side by side with a door provided in each front opening. Yes. The temperature switching chamber (20) is not limited to the above temperature zone, but may be switched to a temperature zone such as a partial freezing temperature, a chilled temperature, a refrigeration temperature, or a vegetable room temperature of −3 ° C. It is good also as an exclusive 2nd freezer compartment. In addition, the second vegetable room, for example, an independent fruit dedicated room may be used. If the room temperature is refrigerated as described above, the ice making room (19) There is no need to divide the space with an insulating wall.

  In the lower part of the ice making chamber (19) and temperature switching chamber (20) that are juxtaposed, a freezing chamber (21), which is a drawer door type as described above and has an enlarged height compared to the conventional one, is the full width of the main body. It is provided over. The freezer compartment (21) has a pair of left and right support frames (not shown) fixed to the inside of a door (22) that closes its front opening so as to be openable and closable. The storage container (23) for storing the frozen food is held by rail members arranged in the front-rear direction on both side wall surfaces, and the drawer system is slidable back and forth.

  On the back of the refrigerator compartment (6) and the frozen storage space (7), a refrigerator for cooling (24), a refrigerator for freezing (25), and fans (26) and (27) corresponding to the respective refrigerators are provided. Cold air generated by each cooler (24) (25) that is arranged and cooled by alternately guiding the refrigerant discharged from the compressor (28) provided in the lower part of the refrigerator body (1) 26) Introduced into the respective storage chambers via ducts according to (27) and cooled, and during the refrigeration operation for operating the refrigeration chamber (6), the temperature was lowered by the refrigeration cooler (24). The cold air is blown out into the refrigerator compartment (6) by the fan (26) to cool the refrigerator storage compartment (10) and the vegetable compartment (11) to an appropriate temperature, and a part of the cold air is put into the cold compartment (15). It is directly introduced and cooled to a lower temperature than in the upper refrigerator compartment (6).

  In the refrigeration operation, the refrigerant is directly introduced into the refrigeration cooler (25), evaporates at a low evaporation temperature, and low-temperature cold air of about −30 ° C. is cooled by a fan (27) as a refrigeration storage space (7) ( It is introduced into 21) and ice making chamber (19), etc., and each chamber is controlled to cool to a predetermined freezing temperature.

  In the refrigeration operation, the refrigerant does not flow into the refrigeration cooler (24), but the refrigeration fan (26) is rotated and the surface temperature is about −3 ° C. because it is in a frosted state. By letting the refrigeration cooler (24) flow down the cold air in the refrigeration room, the frost adhering to the cooler is melted by circulating air at 0 ° C or higher, and at the same time, high humidity that contains a lot of moisture due to melting of the frost Low temperature cold air is allowed to flow into the vegetable compartment (11) from the refrigerated storage compartment (10).

  As a result, the temperature in the vegetable compartment (11) is cooled to about 2 ° C., and on average it can be kept at 4 ° C., and the chilled storage compartment ( 10) The humidity in the vegetable room (11) is as high as 80%. In addition, if the stored vegetables are stored, the transpiration action further increases the humidity to 90 to 95%. Therefore, the vegetable compartment (11) can keep the vegetables inside even when the front is open. A humid atmosphere that does not dry can be maintained.

  As described above, the vegetable compartment (11) is partitioned by the vegetable container (13) arranged at the bottom of the refrigerator compartment (6) and the ceiling plate (12) installed on the top, so that the refrigerator When an independent vegetable compartment is arranged in the middle of the main body in the height direction and a freezer storage compartment is arranged above and below it, it is necessary to provide heat insulating partition walls above and below, and a dedicated pull-out door and rail mechanism Compared to the configuration that requires this, at least one heat insulating partition wall can be reduced, so that the effective storage capacity can be greatly increased not only in the height direction but also in the width and depth directions. is there. In addition, as described above, since there is no dedicated door and the rail mechanism is simplified, the cost can be greatly reduced. Further, since the number of doors is reduced, the dew condensation phenomenon at the front opening can be suppressed and the opening. Therefore, power leakage can be reduced.

  And since the vegetable compartment (11) is arrange | positioned in the refrigerator compartment (6), both storage of the refrigerator compartment door and the vegetable compartment door are opened by the storage of the refrigerator food and vegetables after shopping, respectively conventionally. There is no need, and there is the convenience that can be done at once by opening the refrigerator door (8). In addition, the height of the upper end of the vegetable compartment (11) is higher than in the conventional configuration, so it is closer to the user's line of sight. It can improve usability.

  As described above, by installing the vegetable compartment (11) inside, the lower end position of the refrigerator compartment (6) becomes longer to a position slightly below the belt line of the user, and at the same time the refrigerator compartment door (8). The image of the entire refrigerator becomes fresh and can be designed with a novel design.

  Therefore, when the refrigerator compartment door (8) (8 ') is opened, it is opened to a position below the user's waist, so that the interior volume is large and a sense of spaciousness in the room can be obtained. In addition, the room is easy to look around, and the vegetable room (11) and the low temperature room (15) are located in the low position in the refrigerator room (6), so that even a heavy object can be easily taken out and the usability is improved. As for the vegetable room (11), the vegetables in the vegetable container (13) are easy to see through the transparent ceiling board (12), and the storage and removal operations are greatly improved.

  In the above embodiment, the refrigerator compartment doors (8) and (8 ') are double doors, so that even if the size is increased, the open / close door can be formed with a relatively light force by suppressing heat leakage, and the refrigerator compartment door ( 8) The vertical dimension of the door has become longer, so the placement conditions for the door inner pocket (29) are relaxed. For example, the storage pocket (30) for PET bottles can be placed in two steps. In addition, it is possible to improve usability by making it easier to take out.

  Moreover, according to the said Example structure, as understood from FIG.3 and FIG.5, between the heat insulation partition wall (5) of a refrigerator compartment (6) lower part, and the horizontal partition plate of a freezer compartment (21) upper part. The vertical partition plate that divides the storage space (19) (20) into the left and right can form a substantially E-shaped reinforcing structure at the intermediate part of the refrigerator body (1), increasing the rigidity as a cabinet and improving the strength. Can do.

  Thus, it was provided in the multi-stage mounting shelf (9) installed in the refrigerator compartment (6), the ceiling plate (12) of the vegetable room, or the cold room (15) below the vegetable room (11). The cryocontainer (15a) and the small case (16) are injection-molded with a transparent resin such as polypropylene colored light blue, for example, but are disposed in the refrigerator compartment (6) as described above, and are refrigerated. The vegetable container (13) housed in the vegetable room (11) occupying the largest space in the room (6) is injection-molded with an opaque material, and its color tone forms the refrigerator compartment (6) It has almost the same color as the inner box (3), for example, white.

  The opaque material mentioned above refers to a material that does not allow light to pass through, and the inside and back side of the material cannot be seen through. Thus, by forming the vegetable container (13) with an opaque material, light can be transmitted. Therefore, as in the case of transparent or colored transparent materials, the thickness of the container structure and the reinforcing ribs are not seen through from the front, so even if it occupies a large space in the refrigerator compartment (6) It is possible to give the user a clean impression.

  Further, as described above, the vegetable container (13) is arranged over the entire width of the inner box (3), and the gap with the side wall of the inner box (3) is as small as possible (for example, 10 mm or less). Because the color of the opaque material is almost the same white color as the surrounding inner box, the outer shell of the container itself is assimilated with the inner box (3), making the border inconspicuous, thereby making the vegetable container (13) The interior of the room can be seen as a large and spacious feeling with a clean impression.

  In addition, when the vegetable container (13) is an opaque body, the lighting of the interior lamp (31) provided on the ceiling of the refrigerator compartment (6) is blocked, and the accessory case (under the vegetable container (13) ( 16) and the inside of the cold room (15) may become dark, but the cold container (15a) and the small case (16) are pull-out type. It will be illuminated from above by the lamp (30), and the inside of the container can be visually recognized and can be taken out and stored without hindrance.

  Moreover, as shown in FIG. 4 which is an enlarged cross-sectional view of the rear of the vegetable compartment (11), the vegetable provided with the LED (33) and the shade (34) above the rear portion of the vegetable container (13) in the vegetable compartment (11). If the lighting device (32) for the room (11) is arranged so that it lights up when the refrigerator door (8) (8 ') is opened, the inside of the vegetable container (13) Since the container has a white color tone, it is brighter and easier to see from the back, and the interior can be shown larger and wider. At the same time, the lower front part of the refrigerator compartment (6) can be illuminated by the illumination from the inside of the vegetable compartment (11), and the inside of the drawn out cryogenic container (15a) and the accessory case (16) can be illuminated.

  In each of the above embodiments, the vegetable compartment (11) is arranged above the small case (16) and the low temperature chamber (15). However, as shown in FIG. You may make it install a vegetable room (11 ') in the lower part of (15').

  In the above description, the vegetable compartment (11) is installed in the refrigerator compartment (6), and the vegetable container (13) disposed in the vegetable compartment (11) has been described as an example. The container is not limited to a vegetable container, and can be similarly applied to any container having a relatively large storage volume installed in the refrigerator compartment (6).

It is a front view of the refrigerator which shows one Embodiment of this invention. It is a longitudinal cross-sectional view of FIG. It is a perspective view which shows the state which removed each door in FIG. It is an expanded longitudinal cross-sectional view of the vegetable compartment back in FIG.
