Description

  The present invention relates to a refrigerator used by dividing a storage space into a plurality of storage rooms.

  In recent years, refrigerators for home use have been commercialized with diversified cooling storage temperatures and many doors provided for each storage room in order to meet various user needs. The refrigerator configuration according to the above is, for example, as shown in FIG. 4, which is a configuration shown in Patent Document 1, with a refrigerator room (60) that is used most frequently and has a large volume arranged at the top of the main body (51). In the lower part, an ice making chamber (62) and a temperature switching chamber (63) having a relatively small storage volume are juxtaposed to the left and right by the horizontal partition plates A (54) and C (57) and the vertical partition plate (56). In this embodiment, the vegetable compartment (65) is installed in the lower part and the freezer compartment (64) is installed in the lowermost part through the horizontal partition plate B (55).

On the other hand, as the volume of the freezer compartment increases, in recent years, as described in Patent Document 1, the freezer compartment is provided as a wide room between the lowermost part of the main body and between the refrigerator compartment and the vegetable compartment. Conventionally, for example, the freezer compartment is divided into left and right parts, doors are provided for each, and various layout configurations for improving usability have been commercialized. The configuration in that case is as shown in FIG. The freezer compartment (64 '), which is divided into the lower part by the partition wall (54') at the uppermost part of the main body (51 '), is divided into left and right parts by the vertical partition wall (56') and closed with a double door revolving door. A refrigerator room (60 ') with a maximum volume is placed below it, and a vegetable room (65') is provided at the bottom. Further, as shown in FIG. 6, the lower part of the refrigerator compartment (60 ″) provided at the uppermost part is partitioned by a partition wall (58 ″) and the lower part is divided into left and right parts by a vertical partition wall (56 ″), The vertical storage spaces formed on the left and right sides were the freezer compartment (64 ″) and the vegetable compartment (65 ″), respectively.

  However, in the configuration described in Patent Document 1, the ice making chamber (62) and the temperature switching chamber (63) disposed between the refrigerator compartment (60) and the vegetable compartment (65) are divided and placed side by side. However, due to the height limit of the entire refrigerator and the relationship with the height position of the other storage rooms, both chambers inevitably become smaller in height with width, making the capacity smaller and difficult to use. Had.

  Moreover, since the storage capacity in the mainstream refrigerator is increased to 400 to 500 L, a large amount of stored items are stored in a pocket inside the door such as the refrigerator compartment (60) as the storage amount in the main body increases. Due to the configuration, the load on the door increases, the squareness of the front of the cabinet collapses due to weight, and the structure deforms into a rhombus, resulting in the possibility of the door falling phenomenon. In order to prevent this, it has been necessary to take measures such as increasing the coupling strength between the partition plates between the storage chambers in the front opening of the cabinet and the T-shaped intersection between the partition plate and the outer box side plate. .

  As the freezer structure related to the above, the left and right freezer compartments (64 ′) shown in FIG. 5 are arranged at the uppermost part of the main body. Since the chamber (60 ') position is lowered, the usability deteriorates, and the upper end of the vertical partition (56') that divides the freezer compartment (64 ') into the right and left has a small engagement margin of about 20 mm, and the plate thickness is also zero. It is fixed to the collar part (52a ') of the outer box (52') which is about 5 mm, and the recent large-sized refrigerator structure is weak in strength and easily deformed.

  In addition, as shown in FIG. 6, when the freezer compartment (64 ″) is formed vertically adjacent to the vegetable compartment (64 ″) below the refrigerator compartment (60 ″) on the left and right, the vertical partition plate (56 ″) The volume of the storage room increases and the volume that cannot be used for storage increases, resulting in a decrease in volumetric efficiency. Naturally, each storage room is in a narrow state and a sufficient width dimension is secured as a storage space. It was not possible and it was not easy to use.

  The present invention has been made in consideration of the above-described circumstances, and provides a refrigerator with a large storage capacity that can easily arrange each storage room with multiple doors and increase the cabinet strength as a structure. For the purpose.

  In order to solve the above problems, the refrigerator of the present invention includes an outer box having a front opening and forming an outer shell, and a refrigerator compartment disposed at the top of the inner box provided with a heat insulating material in the outer box. And a storage space formed by upper and lower horizontal partition plates and partition walls whose left and right ends are fixed to the front surface of the outer box at the lower part of the refrigerator compartment, and upper and lower ends fixed to the upper and lower horizontal partition plates to store the storage. A vertical partition plate that divides the front opening of the space into left and right, and a horizontal partition whose left and right ends are fixed to the outer box of the opening and the vertical partition plate so as to divide the front opening on one side of the divided space up and down A plurality of storage chambers are formed by the left and right and upper and lower divisions.

  According to the present invention, it is possible to improve the usability of storing and taking out each storage chamber in a large-capacity refrigerator having a large number of storage chambers, each opening of which is closed with a door, and increasing the cabinet strength as a structure. can do.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. As shown in FIG. 1 which is a front view of the refrigerator and FIG. 2 which is a front view of a state where the door is removed from FIG. 1, the refrigerator main body (1) includes an outer box (2) which forms an outer shell, and a synthetic resin. It is formed by an inner box (3) that is formed of a molded product and forms a storage space inside, and a urethane foam heat insulating material filled between the inner and outer boxes (2) and (3).

  The refrigerator main body (1) as a heat insulating casing has an approximate width dimension of slightly less than 900 mm, and a height of about 1800 mm, which is almost half the height of the outer shell and is almost the height of the user's waist. At the position corresponding to the height, the horizontal partition plate A (4) to the left and right is fixed to the flange (2a) forming the front opening of the outer box (2) by screwing or welding, and the space below it is further provided. The horizontal partition plate B (5) is fixed to the upper and lower positions, for example, at positions that are divided into about 55:45 as in the above.

  And between the horizontal partition plates A (4) and B (5) attached above and below, the left and right spaces are divided into, for example, about 40; A vertical partition plate (6) screwed to A (4) and B (5) is fixed, and one side of this vertical partition plate (6) and outer box (2), in this embodiment, the left outer The horizontal partition plate C (7) installed between the box flange (2a) divides the space up and down at substantially equal intervals.

  The front opening of the outer box (2) is divided into a plurality of, specifically five, by the respective partition plates, and the inner box (3) and the partition wall extending in a plane shape in the room direction for each section. By arranging (8), an independent storage space is formed inside the heat insulating casing.

  The storage space in the outer shell is provided with the horizontal partition plate A (4) and the heat insulating partition wall (9) provided with a refrigerator compartment (10) at the uppermost part of the main body and provided with a heat insulating partition wall (8) below the storage room. The horizontal partition plate B (5) is used as a refrigerated storage space (11), and the vertical partition plate (6) and the left side ridge (2a) of the outer box are partitioned by a horizontal partition plate C (7). A relatively small ice-making chamber (12) with an automatic ice maker is installed in the upper part of the space, and the lower part is installed as a temperature switching chamber (13) of almost the same volume. The ice making chamber (12) and the temperature switching chamber (13) are arranged adjacent to each other in a freezing chamber (14) having a larger storage capacity.

  Below the horizontal partition plate (5) forming the lower side of the frozen storage space (11) formed by the ice making room (12), the temperature switching room (13) and the freezing room (14), a vegetable room (15) is provided. They are provided independently, and a dedicated door is provided at the front opening of each of the storage chambers so as to be freely opened and closed.

  That is, as shown in FIG. 1, the refrigerator compartment (10) has the largest storage volume and is frequently used, so that the double doors are pivotally supported by hinges provided on both sides of the front opening. The ice making room (12), temperature switching room (13), freezer room (14), and vegetable room (15) located at the bottom have a smaller storage capacity than the refrigerated room (10). Due to its small size and ease of use due to its installation height, the container held on the support frame fixed to the back side of the door is slid back and forth with the rail member provided on the indoor wall surface, and is pulled out of the room with the door opening operation. A well-known drawer door system for storing and taking out food from the top opening is adopted.

  Further, as shown in FIG. 3, which is an arrangement state of a cooler, a cold air duct, and the like in the storage chamber of FIG. (18) is provided, and the cold air generated by the refrigeration cooler (16) is introduced from the discharge duct (18) into the refrigeration room (10) through the outlet (19) by the fan (17) to cool the room. Then, it is controlled so that only the refrigerator compartment (10) is cooled to the set temperature by circulating from the suction port (20) back to the cooler (16).

  On the other hand, a freezing storage space (11) comprising the freezing chamber (14), the ice making chamber (12), and the temperature switching chamber (13) is provided at the back of the freezing chamber (14) disposed on the right side portion below the center of the main body. The refrigeration cooler (21) that cools the air is arranged, and the cold air generated by the cooler is blown out from the freezer outlet (23) into the freezer compartment (14) by the fan (22). A part of the air is introduced into the ice making chamber (12) from the blower outlet (25) through the discharge duct (24) and further to the temperature switching chamber (13) from the blower outlet (26) to cool them. (27) From (28), through the return duct for freezing (29), and merged with the return cold air from the suction port (30) formed below the freezer compartment (14) to the freezer cooler (21) Return the cold air circulation, and use a cold air damper (not shown) to store each storage room in the frozen storage space (11). It is intended to cool to a constant temperature.

  The vegetable room (15) arranged at the lowermost part of the storage room space is configured to transfer heat from the low-temperature frozen storage space (11) provided in the upper part through the heat insulating partition wall (9) and the heat insulating partition wall (9 ) Is indirectly cooled by heat transfer from the freezing return duct (29). At this time, in order to increase the amount of heat transfer from the frozen storage space (11) to the vegetable compartment (15), the thickness of the heat insulating partition wall (9) is reduced, and the freezing return duct (29) is You may make it cool by the slight heat transfer by the heat leakage by arrange | positioning widely inside the heat insulation partition wall (8). In addition, when the degree of cooling on the frozen storage space (3) side is large, the vegetable compartment (9) is supercooled with respect to a predetermined temperature due to heat transfer from the heat insulating partition wall (8). What is necessary is just to adjust so that a vegetable room may become suitable temperature by arrange | positioning a heater etc. to the ceiling surface of (9), and carrying out energization control.

  The outer box (2) forming the outer shell of the refrigerator main body (1) is formed by rolling a thin steel plate having a thickness of about 0.5 mm into a substantially inverted U shape by roll forming, and the ceiling and both sides of the main body. A plate portion is formed, and the flange portion (2a) is formed to be bent to a thickness of about 20 mm around the front surface of the housing and overlap to form an opening. Even if the plates are joined at the flange portion (2a), the strength as a cabinet structure is not sufficient.

  For this reason, when the load on the door is large as described above, there is a concern that the cabinet may be deformed into a diamond shape. However, according to the configuration of the embodiment of the present invention, the flange (2a The horizontal partition plates A (4) and B (5) fixed to the upper and lower ends of the vertical partition plate (6) are joined to each other in a T shape by screws or the like. (4), (5) and (6) are formed by angle forming a steel plate having a thickness of about 1.0 mm, and the rigidity is much stronger than the flange (2a) of the outer box. If the shape is maintained, that is, fixed so that the squareness does not collapse, the strength as a cabinet can be sufficiently secured, and deformation in which the entire front opening is distorted into a rhombus can be prevented.

  Reinforcing effect by the T-shaped intersection formed in the center of the cabinet by the combination of the upper and lower horizontal partition plates A (4), B (5) and the vertical partition plate (6) forming the frozen storage space (11) Thus, the refrigerator main body (1) is capable of maintaining a large rigidity over the whole, and is further coupled with a horizontal partition plate C (7) that is coupled to the vertical partition plate (6) from one side. Therefore, the structure strength against strain is further improved.

  In the above configuration, the refrigerator compartment (10) is provided above the frozen storage space (11), and the vegetable compartment (15) is provided below the entire width of the main body. Reinforcing structure made of T-shaped structure can be concentrated and arranged in the frozen storage space (11) part in the central part of the main body while suppressing the lengthening, and the rigidity as a cabinet can be increased. However, the present invention can also be applied to a form in which a storage room such as a vegetable room (15) below is not provided. That is, when the lower part of the frozen storage space (11) is the bottom surface of the main body, this part is not a partition plate, but a front plate made of steel plate, which is a separate member from the outer box, is arranged. Since the front plate is also a thick rigid body, it sufficiently functions as a reinforcing material.

  At this time, since the space surrounded by each partition plate in the above embodiment is a frozen storage space (11), the heat insulation thickness of the left and right side walls of the main body is formed thick in order to prevent heat leakage. Is further improved.

  The upper and lower ice making chambers (12) which are the first and second storage chambers formed by the horizontal partition plates A (4), B (5), C (7) and the vertical partition plate (6). And a temperature switching chamber (13), and a freezing storage space (11) consisting of a freezing chamber (14) which is a third storage chamber disposed laterally adjacent to these upper and lower chambers, is a conventional storage space shown in FIG. Compared to the configuration where the vegetable compartment (65) and freezer compartment (64) are provided below or above the ice making chamber (62) and the temperature switching chamber (63) placed side by side over the entire width of the main body, Since there is no horizontal partition plate (57) in the case of normal refrigerator width dimensions, and when the refrigerator width is wider, the volume of the heat insulation partition wall portion does not exist is widened as a storage space, The storage capacity as a whole increases. In addition, the freezer compartment (14) with a large storage volume arranged adjacent to the left side of the ice making chamber (12) and the temperature switching chamber (13) in FIG. Therefore, the interior of the storage space can be used conveniently by dividing the room into two or three stages according to the stored items.

  The ice making chamber (12), the temperature switching chamber (13) and the freezing chamber (14) constituting the frozen storage space (11) are adjacent to each other, of which the freezing chamber (14) and the ice making chamber (12) Is basically the same refrigeration temperature zone, and does not require a heat insulating partition wall between the chambers on the indoor side of each partition plate, and the switching temperature of the temperature switching chamber (13) is If the switching is performed at a relatively low temperature, for example, a freezing temperature, a soft freezing temperature of about −9 ° C., a partial freezing temperature of −3 ° C. or a low temperature of about 0 ° C. As the temperature difference between each chamber is reduced, the insulation thickness of each partition wall can be reduced, and the heat insulation power can be reduced compared to the conventional one, which can contribute to cost reduction and the freezing storage space (11 Effective use as storage volume) Is something that can be done.

  In the above embodiment, the storage chambers constituting the frozen storage space (11) have been described as the ice making chamber (12), the temperature switching chamber (13), and the freezing chamber (14). The ice making chamber (12) and the temperature switching chamber (13) are smaller in volume than the freezing chamber (14) and cooled to the freezing temperature, and the second freezing chamber (12) The freezer compartments are arranged adjacent to each other, and used separately according to each storage volume, adjacent to the third freezer compartment (14) arranged on the other side, that is, on the right side in FIGS. May be.

  In the above embodiment, the space formed by the horizontal partition plates A (4), B (5), C (7) and the vertical partition plate (6) is the frozen storage space (11). The present invention is not limited to this, and is not shown again. However, the chamber (15) below the horizontal partition plate B (5) disposed below the first to third storage chambers shown in FIG. The other side divided into the left and right by the vertical partition plate (6), that is, the right side chamber (14) in FIG. 2 is a vegetable room and the lower storage room (13 ) As an ice making room and communicated with a freezing room below the ice making room, and the storage room (12) above the ice making room may be a second vegetable room or a temperature switching room.

  With this layout, the vegetable room can be positioned above the user's convenience, and the ice making room can be adjacent to the freezing room. The volume can be increased.
