  FIG. 1 is a perspective view of a refrigerator according to an embodiment to which the present invention is applied as viewed from the front, and FIG. 2 is a conceptual cross-sectional view taken along line AA of FIG.

  As shown in FIG.1 and FIG.2, the refrigerator 1 of this embodiment has the refrigerator compartment 2 which is a storage room of the refrigerating temperature zone of about 6 degreeC in the uppermost part, and the storage room of the refrigerating temperature zone of about 6 degreeC in the lowermost part. And a freezing temperature zone of 0 ° C. or lower (for example, about −20 ° C. to −20 ° C.) that is adiabatically partitioned from both the refrigerator compartment 2 and the vegetable compartment 5. As shown in FIG. 2, an ice making room 3a, a quick freezing room 3b, and a freezing room 4 that are freezing rooms in a temperature zone of 18 ° C. are partitioned and arranged by partition walls k1, k2, and k3, respectively.

  The refrigerator 1 is provided with doors 6 to 10 having a heat insulating structure for closing front openings of the refrigerator compartment 2, the ice making room 3a, the quick freezing room 3b, the freezing room 4 and the vegetable room 5 on the front surface, excluding the doors 6 to 10. The outer peripheral casing portion is configured to include a urethane foam heat insulating material and a vacuum heat insulating material (not shown) for heat insulation from the outside air between the steel plate outer box 11 and the resin inner box.

  The refrigerator compartment door 6 (6a, 6b) which closes the front opening part of the refrigerator compartment 2 is comprised with the double doors of a double door type, on the other hand, the ice making compartment door 7 which obstruct | occludes the front opening part of the ice making compartment 3a, A quick freezer door 8 that closes the front opening of the quick freeze room 3b, a freezer door 9 that closes the front opening of the freezer room 4, and a vegetable room door 10 that closes the front opening of the vegetable room 5 are stored. It is comprised by the drawer-type door from which an indoor container is pulled out together.

  In the refrigerator 1, the refrigeration cycle for performing refrigeration and refrigeration is configured in such a manner that a compressor, a condenser, a capillary tube, an evaporator serving as a cooling source that takes away the heat of vaporization of the refrigerant, and a compressor are connected in this order. ing.

  The evaporator serving as the cooling source is installed behind the freezer compartments 3 and 4, and the cooler air of the evaporator is sent to the ice making chamber 3 a, the quick freezer compartment 3 b, and the freezer compartment 4 by the blower fan, and below the refrigeration temperature. Then, it is sent to each storage room of the refrigerator compartment 2 and the vegetable compartment 5 through the openable and closable damper device. The cold air has a cold air circulation structure that is circulated after each storage chamber is cooled, and the refrigerator compartment 2, the ice making compartment 3a, the quick freeze compartment 3b, the freezer compartment 4 and the vegetable compartment 5 have temperature sensors. It is maintained at a predetermined temperature by temperature control by the control device used.

  As shown in FIG. 3 of the sectional view taken along the line B-B in FIG. 1, the refrigerator compartment door 6a is supported so as to be rotatable about a support shaft S1, and is made of a semi-transparent resin-molded pocket-shaped resin. The door storage 6a1 protrudes on the inner side, and a rotating partition 6a2 configured to be swingable by a biasing force of a torsion coil spring and a guide is provided on the rear surface thereof.

  The rotating partition 6a2 prevents cold air from leaking between the refrigerator compartment doors 6a and 6b at a position along the left refrigerator compartment door 6a when the refrigerator compartment doors 6a and 6b are closed (see FIG. 1). When the refrigerator door 6a is opened, the refrigerator door 6a is rotated in the thickness direction (indicated by a two-dot chain line) so as not to disturb the user.

  Further, the right refrigerator compartment door 6b is supported so as to be rotatable about the support shaft S2, and a pocket-like semi-transparent resin-molded door storage 6b1 is provided on the inner side so as to store a drink or the like. .

  The chilled chamber shown in FIG. 3 is maintained in a chilled temperature zone (for example, a temperature zone of about 0 to 2 ° C.).

  As shown in FIG. 3, when the refrigerator compartment door 6b is closed, a predetermined space is formed between the door storage 6b1 of the refrigerator compartment door 6b and the chilled compartment lid 16 of the chilled compartment 13, and does not contact each other. It is configured as follows. And the chilled room 13 is comprised by the box shape of the width | variety same as the width | variety of the refrigerator compartment door 6b which is one door of a double door, or narrower than it.

  FIG. 4 is a perspective view of the structure of the chilled chamber 13 as viewed obliquely from above and front.

  The chilled chamber 13 has an opening on the upper surface and the front surface and has a flat, substantially rectangular parallelepiped outer shell (housing portion) 14 that covers the opening. And a chilled chamber lid 16 that opens and closes forward and backward.

  The outer member 14 is resin-molded using ABS (resin containing acrylonitrile, butadiene, styrene), AS (resin containing acrylonitrile, styrene) or the like, and has left and right side walls 14a, 14b, a bottom wall 14c, and a rear wall 14d (FIG. 3), and an upper surface having a front wall 14e and a shape having an open front surface.

  FIG. 5 is a conceptual view of the chilled chamber 13 shown in FIG.

  As shown in FIG. 5, the chilled chamber lid 16 has a substantially rectangular shape when viewed from the front, and has an elongated shape in the left-right direction. Further, a cover portion 26 extending integrally from the left end to the right end is provided on the front surface of the chilled chamber lid 16. The front side of the cover portion 26 has a flat shape over the entire width of the chilled chamber lid 16, and the design is improved. On the back surface of the chilled chamber lid 16, an elastic packing 16p is disposed on the inner peripheral edge that abuts the outer shell member 14 when the chilled chamber lid 16 is closed. The packing 16p and the outer shell member 14 are chilled. Sealing between the chamber lids 16 is performed.

  FIG. 6 is a view showing a state in which the chilled chamber lid 16 is locked to the outer member 14 by the cover portion 26.

  As shown in FIG. 6, metal support portions 28 and 29 to which guide rollers (sliding portions) 31 are attached are provided at both left and right ends of the cover portion 26. On the other hand, on the left and right side walls 14a, 14b outside the chilled chamber 13, a curved guide portion 30 formed of resin is provided. For this reason, when the cover part 26 is rotated, the guide roller 31 slides along the guide part 30, and the chilled chamber lid 16 is attracted to the outer member 14 and locked. When the chilled chamber 13 has a decompression pump, the chilled chamber lid 16 is further attracted by depressurizing from this state, and the packing 16p is strongly pressed against the opening 14e. The sealing property with the outer member 14 is improved. Further, when the cover portion 26 is rotated, the guide roller 31 is brought into contact with the guide portion 30 with a strong force, giving a heavy feeling to the user who operates the cover portion 26, and a click feeling when locked. Has been granted.

  Next, the structure of the cover part 26 provided in the chilled chamber lid 16 shown in FIG. 5 will be described.

  The cover part 26 is resin-molded using ABS, and has a full width of the chilled chamber lid 16. The cover portion 26 has a recess formed in the inner surface at the center in the left-right direction, and plays a role as an operation portion that is grasped and operated by the user. In the present embodiment, since the operation part is integrally formed of resin as a part of the cover part 26, the strength is improved even with a simple structure.

  In particular, since 5% or more of glass fibers are mixed in the resin material of the cover portion 26, the rigidity is high and there is no fear of deformation during operation. Further, deformation becomes difficult to occur due to the load of the food material or reduced pressure, and sealing performance can be secured. Even if the glass fiber ratio is less than 5%, a certain degree of effect can be expected. Moreover, since the cover part 26 of this embodiment is shape | molded by a heat cycle, a moldability increases and a sink mark etc. do not arise in the front.

  Furthermore, in this embodiment, the concave part 32 which forms the space where the cover part 26 rotates is formed in the front side of the main body of the chilled chamber lid 16, and this concave part 32 respond | corresponds to the position of an operation part. It extends from the left end to the right end as well as the middle. For this reason, it becomes difficult for the door storage 6b1 of the refrigerator compartment door 6b and the chilled chamber lid 16 to interfere, and the capacity of the door storage 6b1 can be increased.

  Further, as shown in FIG. 7, a case 35 for accommodating the catalyst can be attached to the back side of the main body of the chilled chamber lid 16. The case 35 contains a catalyst that decomposes ethylene gas generated from food in the chilled chamber 13 into carbon dioxide, specifically, a transition metal catalyst such as platinum or ruthenium.

  Here, a rib 35 t is provided on the bottom surface of the case 35, and the case 35 is attached to the chilled chamber lid 16 by inserting the rib 35 t into a groove 16 m formed on the back surface of the chilled chamber lid 16. The case 35 is a place that is difficult to see between the container 17 that is opened and closed together with the chilled chamber lid 16 and the back side of the chilled chamber lid 16, and that is a cover portion 26 formed of an opaque resin. It is difficult to see from the front because it is hidden behind. Further, it is impossible to remove the case 35 unless the chilled chamber lid 16 is removed from the container 7. Therefore, it is possible to prevent the user from removing the case 35 by mistake.

  In addition, a plurality of reinforcing ribs extending in the vertical direction are provided on the back side of the chilled chamber lid 16, and a storage space in the chilled chamber 13 is provided by arranging a case 35 between the reinforcing ribs. I try not to suppress it. Furthermore, since the installation location of the case 35 is outside the container 17, the condensed water hardly reaches the case 35, and the catalytic reaction is prevented from decreasing due to contact between the catalyst and water. On the other hand, since the case 35 is installed in the chilled chamber lid 16, the catalyst efficiently comes into contact with air as the chilled chamber lid 16 is opened and closed, and the catalytic reaction is activated.
