Description

[Technical field]

[0001] The present invention relates to a refrigerator. [Background technology]

[0002] Some refrigerators are equipped with indirectly cooled storage compartments such as chilled compartments that prevent food from drying out by adopting an airtight structure that does not allow dry air to enter. For example, Patent Document 1 discloses that a storage unit incorporated in a refrigerator's refrigeration compartment has a housing and a storage section, and the storage section has a front panel and a flat-bottom container (paragraphs 0012, 0019, figures 1-2). Patent Document 1 also discloses that a slide rail mechanism attached to the front panel and a slide rail mechanism attached to the housing assist in taking food in and out of the storage section (paragraph 0020, figure 2).

[0003] [Patent Document 1] Special Publication No. 2010-529405 Summary of the Invention [Problem to be solved by the invention]

[0004] In the refrigerator described in Patent Document 1, the rollers at the bottom of the storage section are provided at the rear end of the flat-bottom container, so the weight of the storage section, including food, is supported mainly by each slide rail mechanism. That is, the further the storage section is pulled out, the greater the moment applied to each slide rail mechanism becomes, so the more the user pulls out the storage section, the greater the force required to pull it out.

[0005] The present invention has been made in consideration of such problems, and has an object to provide a refrigerator that allows a user to smoothly insert and remove storage containers and has high operability. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems, the refrigerator of the present invention includes an outer container having an opening at the front, a structure on which the outer container is placed, a storage container that can slide in the front-to-back direction within the outer container, and a support part that contacts the structure and supports the front side of the storage container when the storage container is pulled out of the outer container. Effect of the Invention

[0007] According to the present invention, a refrigerator with high operability can be provided, allowing the user to smoothly insert and remove storage containers. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, modes (embodiments) for carrying out the present invention will be described.

[0010] (Overall configuration of refrigerator) 1 is a front view showing a refrigerator according to an embodiment of the present invention. In the following description, a six-door refrigerator 1 will be taken as an example, but the refrigerator is not limited to six doors.

[0011] As shown in Fig. 1, the insulated box 10 of the refrigerator 1 has storage compartments arranged in the following order from above: a refrigerator compartment 2, an ice-making compartment 3 on the left and right, an upper freezer compartment 4, a lower freezer compartment 5, and a vegetable compartment 6. The refrigerator 1 is equipped with doors that open and close the openings of each storage compartment. These doors are rotating refrigerator compartment doors 2a and 2b divided into left and right doors that open and close the opening of the refrigerator compartment 2, and a pull-out ice-making compartment door 3a, an upper freezer compartment door 4a, a lower freezer compartment door 5a, and a vegetable compartment door 6a that open and close the openings of the ice-making compartment 3, the upper freezer compartment 4, the lower freezer compartment 5, and the vegetable compartment 6, respectively.

[0012] Ice-making compartment 3, upper freezer compartment 4, and lower freezer compartment 5 are basically storage compartments whose interiors are kept in the freezing temperature range (below 0°C), for example, at an average of about -20°C, while refrigerator compartment 2 and vegetable compartment 6 are storage compartments whose interiors are kept in the refrigeration temperature range (above 0°C), for example, refrigerator compartment 2 at an average of about 4°C and vegetable compartment 6 at an average of about 7°C.

[0013] Fig. 2 is a cross-sectional view taken along the line AA in Fig. 1. As shown in Fig. 2, the refrigerator 1 is configured such that the outside and the inside are separated by an insulated box 10 formed by filling a space between an outer box 10a (made of steel plate) and an inner box 10b (made of synthetic resin) with a foam insulation material (e.g., urethane foam). In addition to the foam insulation material, vacuum insulation material 25, which has a lower thermal conductivity than the foam insulation material, is mounted between the outer box 10a and the inner box 10b in the insulated box 10, thereby improving the insulation performance without reducing the food storage volume.

[0014] The refrigerator compartment 2 is separated from the ice-making compartment 3 and the upper freezer compartment 4 by a heat-insulating partition wall 27. The lower freezer compartment 5 and the vegetable compartment 6 are separated by a heat-insulating partition wall 28. In addition, a partition 29 is provided at the front edge between the ice-making compartment 3 and the upper freezer compartment 4, and a partition 30 is provided at the front edge between the ice-making compartment 3 and the upper freezer compartment 4 and the lower freezer compartment. These partitions make it difficult for air in each storage compartment to leak outside through the gaps in the doors 3a, 4a, 5a, and also makes it difficult for air from outside to enter each storage compartment.

[0015] The refrigerator compartment doors 2a and 2b are provided with multiple door pockets on the inside of the compartment. The refrigerator compartment 2 is divided into multiple storage spaces by shelves 34a, 34b, 34c, and 34d. The ice making compartment 3, the upper freezer compartment 4, the lower freezer compartment 5, and the vegetable compartment 6 are provided with an ice making compartment container (not shown), an upper freezer compartment container 4b, a lower freezer compartment container 5b, and a vegetable compartment container 6b, which are pulled out together with the doors 3a, 4a, 5a, and 6a, respectively.

[0016] The first evaporator 14a, which is a refrigeration evaporator, is provided in a refrigeration evaporator chamber provided at approximately the rear of the refrigeration chamber 2. The air that has been cooled by heat exchange with the first evaporator 14a is sent to the refrigeration chamber 2 by a first fan 9a provided above the first evaporator 14a, and cools the interior of the refrigeration chamber 2. The air sent to the refrigeration chamber 2 returns to the refrigeration evaporator chamber and is cooled again by the first evaporator 14a.

[0017] The second evaporator 14b, which is a freezing evaporator, is provided in a freezing evaporator chamber provided at the rear of the lower freezing chamber 5. The air that has been cooled by heat exchange with the second evaporator 14b is sent to the ice making chamber 3, the upper freezing chamber 4, and the lower freezing chamber 5 by the second fan 9b provided above the second evaporator 14b, and cools each storage chamber. The air sent to each storage chamber returns to the second evaporator chamber 8b and is cooled again by the second evaporator 14b. Furthermore, although not shown, a vegetable chamber air duct and a vegetable chamber damper are provided, and the second evaporator 14b also cools the vegetable chamber 6. In addition, the heat-insulating partition wall 28 is provided with a return air duct 24 that runs from the vegetable chamber to the second evaporator chamber 8b.

[0018] (Chilled room configuration) In the refrigerator compartment 2, the space above the heat-insulating partition wall 27 and below the shelf 34d is provided with the chilled compartment 7, which is maintained at a chilled temperature range (for example, -1°C to 2°C). A pump (not shown) is provided at the back of the chilled compartment 7 to suck air from the chilled compartment 7. When the pump is driven with the lid closed, the air pressure in the chilled compartment 7 becomes approximately 0.8 atm. As a result, the lid prevents cold air from being blown directly into the chilled compartment 7, and the reduced pressure creates an environment with a reduced oxygen concentration, making it a storage space in which food drying and oxidation are suppressed. The chilled compartment 7 is cooled mainly by cold heat transferred from the ice-making compartment 3 and upper freezer compartment 4 located below it.

[0019] Fig. 3 is a perspective view showing the exterior of chilled compartment 7 when lid 73 is closed, and Fig. 4 is a right side view showing chilled compartment 7 when lid 73 is open. Chilled compartment 7 is made up of outer container 71 (box) with an open front, storage container 72 (tray) that can slide back and forth within outer container 71, and lid 73 that opens and closes the front of outer container 71.

[0020] The lid body 73 mainly has a lid main body 73a arranged on the front side of the storage container 72, a cover member 73b covering the front side of the lid main body 73a, a handle 73c located in front of the curved shape of the lid main body 73a and extending in the left-right direction, a roller 73d (support portion) provided on the lower rear side of the lid main body 73a, and a gasket 73e provided on the rear side of the lid main body 73a.

[0021] The front side of the lid body 73a has a curved shape recessed toward the rear at the center in the up-down direction, and this curved shape extends continuously in the left-right direction. In addition, a recess for attaching a packing 73e is continuously formed on the periphery of the rear side of the lid body 73a. The cover member 73b is a flat member formed around the front side of the lid body 73a. The handle 73c is held by the user when opening or closing the chilled compartment 7.

[0022] The rollers 73d are in contact with the upper surface of the structure (insulating partition wall 27) to support the storage container 72 when the storage container 72 is pulled out from the outer container 71. When the lid body 73 is closed and the storage container 72 is inside the outer container 71, the rollers 73d are located outside the outer container 71 (outside in the left-right direction). However, it is preferable that most of the rollers 73d are arranged in a position hidden behind the lid body 73a when viewed from the front side, and only a small part of the lower part of the rollers 73d protrudes downward from the lid body 73a. In this case, the rollers 73d are almost invisible to a user standing at the front side. The method of fixing the rollers 73d to the lid body 73a will be described later with reference to FIG. 7. The packing 73e plays a role in sealing the chilled chamber 7 when the lid body 73 is closed, and has a thick portion 73e1 and a fin portion 73e2 (see FIG. 8). The thick portion 73e1 is press-fitted into a recess formed on the rear side of the lid body 73a. The fin portion 73e2 is formed behind the thick portion 73e1 and extends gradually away from the thick portion 73e1 toward the periphery, and when the lid body 73 is closed, it comes into contact with the opening of the outer shell container 71 and elastically deforms. This improves the airtightness of the chilled chamber 7.

[0023] The storage container 72 mainly comprises a container body 72a in which food is stored, a sliding rib 72b formed on the underside of the bottom surface of the rear part of the container body 72a, and an engagement rib 72c extending outward from the left and right side surfaces of the rear part of the container body 72a. The container body 72a is attached to a lid body 73a, and when the lid body 73 is opened or closed, the storage container 72 also opens and closes (slides forward and backward).

[0024] 4, the outer shell container 71 mainly includes an outer shell main body 71a that is open at the front, side rails 71b that extend in the front-rear direction on the inside of the left and right side surfaces of the outer shell main body 71a, a sliding surface 71c formed on the inside of the bottom surface, a plurality of reinforcing ribs 71d that extend in the up-down direction on the outside of the top surface and bottom surface of the outer shell main body 71a, and a reinforcing member 71e attached to the outside of the top surface of the outer shell main body 71a. The outer shell main body 71a, the side rails 71b, the sliding surface 71c, and the reinforcing ribs 71d are integrally formed of resin such as ABS resin or AS resin, and the reinforcing member 71e is made of metal. A method for attaching the reinforcing member 71e to the outer shell main body 71a will be described later.

[0025] The outer shell body 71a is placed on the upper surface of the structure (insulating partition wall 27). At the front end of the side rail 71b, a stopper 71f that abuts against the engagement rib 72c of the storage container 72 is formed, and the position of the storage container 72 is regulated so that the lid body 73 is not pulled out beyond a certain pull-out dimension. The sliding surface 71c has an inclination that is inevitably formed when the outer shell body 71a is integrally molded, and has an inclination such that the front is lower. When the lid body 73 and the storage container 72 are pulled out, the engagement rib 72c of the storage container 72 moves below the side rail 71b and finally abuts against the stopper 71f of the side rail 71b, and the sliding rib 72b of the storage container 72 moves while sliding on the sliding surface 71c. At this time, it is desirable that the engagement rib 72c and the side rail 71b move in a separated state, but they may be configured to move in a contacting state as long as the movement is not hindered. Members that slide in contact with each other, such as the engagement rib 72c and the side rail 71b, and the sliding rib 72b and the sliding surface 71c, may be coated with a lubricant to reduce friction during sliding.

[0026] (Comparative Example) Here, the structure of the chilled compartment according to the comparative example will be described with reference to Figs. 5 and 6. Figs.

[0027] FIG. 5 is a diagram showing an outer shell container in a chilled compartment according to a comparative example. In the comparative example, when the lid and the storage container are pulled out, the engagement rib of the storage container moves forward while abutting against the lower surface of the side rail. At this time, if the pulled out lid comes into contact with the upper surface of the structure, it may damage the structure. For this reason, the side rail is designed to have a lower front and a steeper inclination than the sliding surface, similar to the sliding surface. That is, the vertical distance between the side rail and the sliding surface is narrower at the front than at the rear. As a result, as the lid and the like are pulled out, the plane S including the sliding rib and engagement rib of the storage container inclines so as to fall backward. That is, the lid is in a floating state relative to the structure. In FIG. 5, the position of the plane S when closed is indicated by S1, and the position of the plane S when opened is indicated by S2.

[0028] Fig. 6 is a diagram showing a storage container in a pulled-out state in a chilled compartment according to a comparative example. As shown in Fig. 6, when the lid and other parts are pulled out, the front side of the storage container is lifted up compared to the rear side, but in the comparative example, since rollers are not provided at the bottom of the lid, the load is supported only at the rear side in a cantilevered state. At this time, the storage container is balanced between a moment M1 that tries to rotate counterclockwise around the sliding rib due to the gravity of the lid, storage container, and food, and a moment M2 that tries to rotate clockwise due to the reaction force that the engagement rib receives from the side rail. The position at which M1 acts corresponds to the center of gravity of the lid, storage container, and food.

[0029] Here, the storage container in the chilled compartment has a width close to that of the refrigerator compartment, and since a large amount of food is stored in it, the moment M1 is likely to be large. In particular, in the chilled compartment, which is premised on decompression, the lid body is inevitably heavy in order to ensure its rigidity, so the moment M1 becomes even larger. Therefore, the more the lid body or the like is pulled forward, the larger the moment M2 applied to the engagement rib and side rail that balances the moment M1 becomes, and a large force is required when the user operates the handle. In other words, in the chilled compartment according to the comparative example, the lid body or the like may not be pulled out smoothly, and there is a concern that the operability may decrease.

[0030] (Example) On the other hand, in the case of the chilled compartment 7 according to the embodiment shown in FIG. 4, when the lid 73 and the like are pulled out, the sliding rib 72b comes into contact with the sliding surface 71c. As the sliding rib 72b slides on the inclined sliding surface 71c, the roller 73d provided on the lower part of the lid body 73a and on the outside of the packing 73e that comes into contact with the opening of the outer shell container 71 when the lid 73 is closed gradually descends and comes into contact with the upper surface of the heat-insulating partition wall 27. Then, the load of the lid 73, the storage container 72, and the food is supported by the roller 73d and the heat-insulating partition wall 27 in the front and by the sliding rib 72b and the sliding surface 71c in the rear, so that no moment M2 that tends to rotate the engagement rib clockwise due to the reaction force received from the side rail is generated. Therefore, the user can smoothly insert and remove the lid 73 and the like, improving operability.

[0031] Here, the inside of the insulating partition wall 27 is filled with a foamed insulating material, and foaming deformation can cause unevenness on the surface of the insulating partition wall 27. If the roller 73d is positioned on this unevenness, the position of the lid body 73 will be shifted up and down relative to the outer container 71. If the lid body 73 is in a vertically shifted state even when the lid body 73 is closed, this will affect the airtightness of the chilled chamber 7. Therefore, when the lid body 73 is closed and the storage container 72 is inside the outer container 71, it is desirable that the roller 73d does not come into contact with the insulating partition wall 27.

[0032] The surface of the heat insulating partition wall 27 is made of resin such as PP, and may be damaged by contact with the main body of the roller 73d, which is made of resin such as POM. Therefore, in this embodiment, an O-ring made of rubber such as NBR or silicone is provided on the outer periphery of the main body of the roller 73d. Since the O-ring on the outer periphery of the roller 73d is softer than the surface of the heat insulating partition wall 27, which is the ground surface, it is possible to prevent the ground surface of the heat insulating partition wall 73d from being damaged when the roller 73d moves on the surface of the heat insulating partition wall 27. Note that the O-ring does not have to be made of rubber as long as it is made of a material softer than the heat insulating partition wall 27. The softness of the O-ring and the heat insulating partition wall 27 is defined by, for example, their respective surface hardness and elastic modulus. In addition, when the lid body 73 is closed, the O-ring on the outer periphery of the roller 73d is separated from the ground surface, so that even if seasoning oil or the like is present on the ground surface, the O-ring is unlikely to continue to be immersed in the oil, and deterioration of the O-ring is suppressed.

[0033] (How to fix the roller) FIG. 7 is a plan view showing a method of fixing the roller to the lid body, and is a view of the front left side of the chilled compartment from below. The main body of the roller 73d is fixed to the lid body 73a via a screw fixing part 73f (positioning part) located on the inside in the left-right direction. FIG. 7 shows how the main body of the roller 73d on the front left side of the chilled compartment is fixed to the lid body 73a via the screw fixing part 73f located on the right side. When the lid body 73 is closed, a clearance CL of a predetermined width is provided between the screw fixing part 73f and the outside of the left side surface at the opening of the outer shell container 71. Similarly, the main body of the roller 73d on the front right side of the chilled compartment is fixed to the lid body 73a via the screw fixing part 73f located on the left side, and a clearance CL of a predetermined width is provided between the screw fixing part 73f and the outside of the right side surface at the opening of the outer shell container 71.

[0034] Fig. 8 is a horizontal cross-sectional view showing the positional relationship between the lid body and the outer container when the lid body, which is provided with rollers and screw fixing parts, is closed as a chilled chamber according to the embodiment, as viewed from below on the front left side of the chilled chamber. A protrusion 71g that protrudes forward is formed on the opposite peripheral edge side of the front surface of the opening of the outer container 71. In the chilled chamber 7 according to the embodiment, as shown in Fig. 8, the protrusion 71g of the outer container 71 abuts against the rear surface of the fin portion 73e2 of the packing 73e provided on the lid main body 73a. In this state, the chilled chamber 7 is well kept airtight.

[0035] Fig. 9 is a horizontal cross-sectional view of a comparative chilled compartment in which the positional relationship between the lid and the outer container is shifted to the right when the lid, which does not have rollers and screw fixing parts, is closed, as viewed from below on the front left side of the chilled compartment. In the chilled compartment in the comparative example, as shown in Fig. 9, the convex part 71g of the outer container 71 does not come into contact with the fin part 73e2, and the front surface of the outer container 71, not the convex part 71g, comes into contact with the rear surface of the fin part 73e2 of the packing 73e. In this state, it may not be possible to ensure airtightness of the chilled compartment.

[0036] In this embodiment, the width of the clearance CL is appropriately set so that the left-right movement of the lid body 73 can be restricted within a range where the protrusion 71g and the fin portion 73e2 of the outer container 71 come into contact with each other. In other words, the width of the clearance CL is narrower than the left-right movement from the state where the protrusion 71g and the fin portion 73e2 come into contact with each other as shown in Fig. 8 to the state where the protrusion 71g and the fin portion 73e2 are no longer in contact with each other as shown in Fig. 9. As a result, when the lid body 73 is closed, the screw fixing portions 73f on both the left and right sides of the chilled chamber play a role in positioning the lid body 73 relative to the outsides of the left and right side surfaces of the opening of the outer container 71 to restrict the left-right movement of the lid body 73, and the airtightness of the chilled chamber 7 can be maintained in a good condition.

[0037] (Reinforcing member) The details of the reinforcing member will be described with reference to Figs. 10 to 12. Fig. 10 is a vertical cross-sectional view of the chilled compartment at the left-right center as viewed from the right. Fig. 11 is a cross-sectional view taken along line B--B of Fig. 3, and is a vertical cross-sectional view of the chilled compartment from the front to the front of the front-rear center. Fig. 12 is an enlarged view of the vicinity of the fastening portion in Fig. 11.

[0038] The reinforcing member 71e is, for example, a plate-like member made of iron that extends in the left-right direction and is provided on the outside of the top surface of the outer shell container 71. In addition, since the reinforcing member 71e is provided in a location where the reinforcing rib 71d does not exist, it is possible to prevent the upper end of the reinforcing member 71e from exceeding the upper end of the reinforcing rib 71d and interfering with the shelf 34d.

[0039] As shown in FIG. 11, the reinforcing member 71e is fastened to the top surface of the outer container 71 at the center in the left-right direction, with the vicinity of both left-right ends as fulcrums. Also, as shown in FIG. 12, a clearance is provided between the upper end of the screw boss portion 71h of the outer container 71 and the lower surface of the reinforcing member 71e. Therefore, even if the pressure inside the chilled chamber 7 is reduced or a large amount of food is placed on the shelf 34d above the chilled chamber 7, the phenomenon in which the center in the left-right direction of the top surface of the outer container 71 sags (inward warping) can be suppressed. That is, the reinforcing member 71e suppresses deformation of the top surface of the outer container 71 and makes it difficult for the vertical position of the opening to change, so that the adhesion between the packing 73e of the lid body 73 and the opening of the outer container 71 is stabilized. As a result, the airtightness of the chilled chamber 7 is improved, and the freshness-preserving performance of food is improved.

[0040] Here, as shown in FIG. 10, the top surface of the outer container 71 has an inclination such that the front is higher than the rear, and therefore the reinforcing rib 71d provided on the front side has a smaller vertical dimension than the reinforcing rib 71d provided on the rear side. If the reinforcing member 71e is provided near the frontmost reinforcing rib 71d, the upper end of the reinforcing member 71e may exceed the upper end of the reinforcing rib 71d and interfere with the shelf 34d. On the other hand, as described above, the reinforcing member 71e plays a role in suppressing the change in the vertical position of the opening of the outer container 71, so it is desirable to provide it as far forward as possible. In consideration of these, the reinforcing member 71e of this embodiment is provided forward of the center in the front-rear direction of the chilled chamber 7 (outer container 71) and rearward of the front end (opening) in the front-rear direction.

[0041] (Additional Note) The present invention is not limited to the above-described embodiment, and includes various modified examples. For example, in the above-described embodiment, the chilled compartment is depressurized by a pump, but the chilled compartment may not be depressurized. In addition, in the above-described embodiment, the lid body and the storage container are separate, and the rollers are provided on the lid body. However, the lid body and the storage container may be integrated, and the rollers may be provided on the storage container. In this case, the rollers may be replaced by support parts that slide on the ground surface without rotating. When the lid body and the storage container are integrated, the number of parts can be reduced, which can reduce manufacturing costs and facilitate assembly of the refrigerator.
