Description

  The present invention relates to a refrigerator.

  As background art of this technical field, there are JP-A-2001-280830 (Patent Document 1) and JP-A-3378187 (Patent Document 2).

  Patent Document 1 discloses that a conventional refrigerator compartment in which a food storage container housed in a food storage chamber having a front opening is supported so that it can be pulled out in the front-rear direction together with a door that opens and closes the front opening is a frame that supports a storage case. The body is configured by the combination of the left and right supports and a connecting member that connects the rear ends of the supports, and "the body extends from the door to the food storage chamber and houses the lower portion of the food storage container. A configuration is disclosed in which a container-like support having an opening on the top surface is provided, and the container-like support is integrally formed with a side wall and a bottom wall by molding a synthetic resin or metal (summary, FIG. 2).

  Patent Document 2 states that “a drawer door provided with a frame on which a case for storing food and the like is attached, a moving roller provided at the rear of the frame, and an inner box of the main body. A rail portion provided on a side wall, in which the moving roller is accommodated and slid, and a side wall surface is curved outward so as to withstand a foaming pressure of a heat insulating material; And a main body side fixed roller that slides ”is disclosed (claim 1).

JP 2001-280830 A Japanese Patent No. 3378187

  In the conventional configuration described in Patent Document 1, that is, the configuration in which the storage case is supported by the support fixed to the door, the mounting position (particularly in the height direction) of the support with respect to the door is important.

  In a typical refrigerator, a drawer-type storage room (freezer room or vegetable room) is placed at the bottom of the refrigerator body, but the top of the door is easy to open and close even if the user does not bend forward. Is provided with a handle.

  In recent years, storage cases in vegetable rooms and freezer rooms can store about 30 to 50 kg of food. In the case of a refrigerator provided with such a storage case, when the distance in the height direction between the position of the handle portion of the door and the position of the frame body supporting the storage case becomes long, when the door is pulled out by placing a hand on the handle portion, A large load is applied to the connection portion between the door and the support, and there is a risk of deformation starting from this connection portion.

  Further, when the door is pulled out, the near side of the support body is lowered, so that the slidability of the support body is deteriorated and it may be difficult to pull out the support smoothly.

  Moreover, when the container-like support is made of metal as in Patent Document 1, the weight increases and the handleability and the portability decrease. In addition, the cost increases. On the other hand, when the container-shaped support is made of a synthetic resin, the container-shaped support may be bent and deformed when the weight of the storage case including the stored item is increased.

  Next, in Patent Document 2, in a door having a smaller amount of storage than a freezer room or a vegetable room (for example, a door having an amount of storage of 10 kg or less such as an ice making room door), a lower part away from a handle portion at the upper part of the door The connecting portion of the frame is provided at the position, that is, inside and below the door. However, in Patent Document 2, since it has a cantilever structure in which the frame and the case are fixedly supported only on the door side, the frame that supports the case is bent when a large load is applied, and the slidability of the frame is reduced.

  Further, in consideration of the amount of bending of the frame, a gap is provided between the case bottom and the storage chamber bottom. Therefore, there was a limit to increasing the case size.

  Therefore, an object of the present invention is to provide a refrigerator that improves the support strength of a storage container having a drawer structure and that can be smoothly pulled out even when the storage container is enlarged.

In order to solve the above problems, for example, the configuration described in the claims is adopted. The present application includes a plurality of means for solving the above-mentioned problems. To give an example, a refrigerator compartment formed in the refrigerator body, a freezer compartment below the refrigerator compartment, and a door for opening and closing the refrigerator compartment. A storage container disposed in the refrigerating chamber, a base on which the storage container is placed, a handle portion at the front of the base, a rail provided on the surface of the refrigerating chamber, and a rear portion of the base. A movable body that moves on the rail, and a first support body that is provided in front of the lower part of the refrigerator compartment and supports the base so as to be movable in the front-rear direction, the first support body, rails, and the height position of each of the sliding portion of the movable body, and at least part of the height position of the finger receiving portion is, as close or become like the height position of the bottom of the base, the housing Between the bottom of the container and the top of the base Characterized in that the formation of the space.

Hereinafter, with reference to drawings, the refrigerator which concerns on Example 1 of this invention is demonstrated concretely. In the drawings, similar parts and arrows are denoted by the same reference numerals, and redundant description is omitted.

<Overall configuration of refrigerator 1>
First, the whole structure of a refrigerator is demonstrated with reference to FIG.1, FIG.2, FIG.3 and FIG. FIG. 1 is a front perspective view of the refrigerator according to the first embodiment of the present invention. FIG. 2 is a front view showing a state in which the refrigerator compartment door of the refrigerator according to the first embodiment of the present invention is opened. FIG. 3 is a longitudinal sectional view of the refrigerator according to the first embodiment of the present invention. FIG. 4 is a rear perspective view in which the right side wall and the back wall of the refrigerator according to the first embodiment of the present invention are omitted.

  In the refrigerator 1, a refrigerator body 3 and a freezer compartment 6 are provided on the top and bottom of a refrigerator body 1 </ b> H constituting the body. The refrigerator compartment 3 and the freezer compartment 6 are partitioned by a partition wall 5a. In addition, the partition wall 5a is equipped with the heat insulating material inside, and functions as a heat insulation partition wall.

  The front upper part of the refrigerator main body 1H is provided with rotating doors 2a and 2b that are provided on the left and right sides and are pivotally supported at one ends by hinges so as to constitute a so-called French door. As shown in FIG. 2, the rotary doors 2a and 2b are refrigerator doors, and the stored items in the refrigerator compartment 3 can be stored and taken out by opening and closing the refrigerator doors 2a and 2b. A drawer door 2c is provided at the front lower part of the refrigerator main body 1H. The drawer door 2c is a freezer compartment door, and stored items in the freezer compartment 5 can be stored and taken out by opening and closing the freezer compartment door 2c.

  In the refrigerator compartment 2, a plurality of shelves 3a on which the stored items are placed, which are supported by protrusions provided on the left and right side walls inside the refrigerator main body 1H, are arranged in the vertical direction. A storage shelf 3b that also serves as a partition between the refrigerator compartment 3 and the chilled chamber 4 is disposed at a position lower than the shelf 3a. Furthermore, the door pocket 8 is provided in the surface (the back side of the refrigerator compartment doors 2a and 2b) facing the refrigerator compartment 2 of the refrigerator compartment doors 2a and 2b.

  A chilled room 4 and a vegetable room 5 are provided in a part of the refrigerator compartment 3. More specifically, a space above the freezer compartment 6 and above the partition wall 5a and behind the refrigerator compartment doors 2a and 2b is formed as a chilled compartment 4 and a vegetable compartment 4. The refrigerated room 3 and the vegetable room 5 are storage rooms in a refrigerated temperature range of about 3 to 5 ° C. as an example. The chilled chamber 4 is a storage chamber in a temperature range of about 0 ° C. as an example.

  A chilled chamber container 4 a is disposed in the chilled chamber 4, and a storage container 50 that is a vegetable chamber container is disposed in the vegetable chamber 5. When the refrigerator compartment doors 2a and 2b are opened, the chilled room container 4a and the vegetable room container 50 are stored in the chilled room 4 and the vegetable room 5, respectively. Then, by pulling out the chilled chamber container 4a and the vegetable chamber container 50, stored items can be stored and taken out in the respective containers. Moreover, it is the structure which accommodates the chilled chamber container 4a and the vegetable chamber container 50 of the withdrawn state in a predetermined position, and closes the refrigerator compartment doors 2a and 2b.

  In the refrigerator 1 of the present embodiment, the refrigerator compartment 3, the chilled compartment 4, and the vegetable compartment 5 constituting the refrigerated space are arranged in order from the top, and the vegetable compartment container 50 is compared with the shelves 3 a and 3 b and the chilled compartment container 4. And has a shape that protrudes forward. As described above, since the vegetable compartment container 50 has a space protruding forward, the storage space of the vegetable compartment 5 can be increased. In addition, the door pocket 8 is not provided in the height position which opposes the vegetable compartment 5 so that it may not interfere with the overhang | projection part of the vegetable compartment container 50. FIG.

  Thus, since the vegetable compartment container 50 has a protruding part in the front, a large amount of vegetables and the like can be accommodated in large quantities. Moreover, by having the door pocket 8 in the position facing the refrigerator compartment 3 and the chilled chamber 4 on the rear side of the refrigerator compartment doors 2a and 2b, it is possible to store the refrigerator in a refrigerator such as a plastic bottle or a paper pack, a seasoning in a bottle or a tube, etc. Necessary foods can be stored effectively, and these foods can be easily put in and out by simply opening one of the refrigerator compartment doors 2a and 2b.

  The cold air cooled by the cooler 12 to be described later drives the cold air blower fan 11 (refrigeration room blower fan 11a, freezer compartment blower fan 11b), so that the cold room 3, the chilled room 4, Cold air flows into the vegetable compartment 5, and cold air flows from the freezer compartment cold air blow duct 18F to the freezer compartment 6.

  The cold air blown to the refrigerator compartment 3, the chilled compartment 4, and the vegetable compartment 5 passes through the refrigerator compartment cool air return duct 17R provided behind the cooler compartment 10 where the cooler 12 is disposed, and enters the cooler compartment 10. Return. Further, the cold air after being blown into the freezer compartment 6 passes through the freezer compartment cold air return duct 17 </ b> F provided at the rear portion of the freezer compartment 6 and returns to the cooler compartment 10.

  Next, a chilled chamber container 4a that can be taken out by being pulled out is disposed in the chilled chamber 4. Since the shelf 3b is disposed above the chilled chamber container 4a, the cold air in the chilled chamber 4 is blocked by the shelf 3b and is difficult to leak out of the container. Moreover, as shown in FIG. 2, the switching lever 4b is provided in the back surface in the refrigerator compartment 3 above the chilled chamber 4. By switching the switching lever 4b to the left and right, it is possible to operate opening and closing of a cold air port (not shown) in the chilled chamber 4. By opening the cold air opening, the cold air is guided into the chilled chamber 4.

  Accordingly, since the user can adjust the temperature in the chilled chamber 3, temperature management suitable for the user can be performed. In the present embodiment, the switching lever 4b is provided on the back of the lowermost stage of the refrigerating chamber 2 in consideration of a height position that is easy to use when operating, but this is not restrictive. The other location in the refrigerator main body 1H may be sufficient, and you may enable it to operate from an external control panel in the state which closed the refrigerator compartment doors 2a and 2b. Further, the information receiving means may be provided in the refrigerator 1 so that the switching input operation can be performed remotely from the mobile terminal or the remote operation means.

  Next, the freezer compartment 6 is a storage room of a freezing temperature zone of about −18 ° C. as an example. In the freezer compartment 6, a drawer-type upper freezer compartment container 6a and a lower freezer compartment container 6b are arranged. The lower freezer compartment container 6b is suspended and supported by a support frame (not shown) connected to the drawer-type freezer compartment door 2c, and is pulled out together with the drawing operation of the freezer compartment door 2c. The upper freezer compartment container 6a may be pulled out together with the lower freezer compartment container 6b, and the upper freezer compartment container 6a remains in the freezer compartment 6 when the freezer compartment door 2c is pulled out. It is good also as a structure which pulls out the freezer compartment 6a independently.

  The cooler room 10 is a space formed to protrude from the rear upper part of the freezer room 6 to the rear part of the vegetable room 5. In the cooler chamber 10, a cooler 10 that constitutes a part of the refrigeration cycle, a cool air blower fan 11 (refrigeration chamber blower fan 11 a, freezer compartment blower fan 11 b) above the cooler 10, A defrost heater 15 is arranged. The cooler 10 is disposed behind the freezer compartment 6. This is because the cooler 10 is at a low temperature in the freezing temperature zone, so that the effect of the low temperature does not reach the adjacent storage room by making it adjacent to the freezer compartment 6 in the temperature zone. At the same time, if it is adjacent to a storage room in a refrigerated temperature zone, not only will the temperature of the cooler 10 rise, but frost tends to adhere and the heat exchange efficiency decreases, so this is also avoided.

  The cold air blower fan 11 is disposed behind the vegetable compartment 5. More specifically, the cooler 12 is arranged as large as possible in the height direction behind the freezer compartment 6, and the cool air blower fan 11 is arranged behind the vegetable compartment 5 above the freezer compartment 6. This is to increase the size of the cooler 12 as much as possible to improve the cooling performance. In particular, it is necessary to improve the cooling performance in a refrigerator such as this embodiment having a large storage space.

  Here, if the cooler 12 is located to the back of the vegetable compartment 5, the vegetable compartment 5 becomes low temperature by the influence of the cooler 12, and the stored vegetables etc. may freeze. Therefore, in this embodiment, the cooler 12 is held at the rear position of the freezer compartment 6 (the height position of the partition wall 5 a), and the cold air blower fan 11 is arranged behind the vegetable compartment 5. Furthermore, a heat insulating partition 5b is arranged in front of the cold air blower fan 11 and behind the vegetable compartment 5. That is, the cooler room 10 and the vegetable room 5 which are the height positions of the cold air blower fan 11 are partitioned insulatively by the heat insulating partition 5b. Therefore, the influence of the low temperature of the cooler chamber 10 on the vegetable chamber 5 is suppressed.

  A machine room 13 is formed in the lower rear part of the refrigerator main body 1H from the back side to the freezer compartment 6 side. The machine room 13 is provided with a compressor 14. The frost adhering to the cooler 12 is melted by the defrost heater 15 and guided to the machine room 13 by the drain pipe 16 and drained.

  In the present embodiment, the cold air blower fan 11 includes two refrigerator air blowers 11a and 11b. When the refrigerator air blower fan 11a is driven, cold air passes through the refrigerator air cooler air duct 18R, and the refrigerator compartment 3, the chilled room 4, and the vegetable compartment 5 are cooled. When the freezer compartment blower fan 11b is driven, cool air passes through the freezer compartment cool air blow duct 18F, and the freezer compartment 6 is cooled.

<Composition of vegetable room 5>
Next, a specific configuration of the vegetable compartment 5 will be described with reference to FIGS. FIG. 5 is a longitudinal sectional view around the vegetable compartment of the refrigerator according to the first embodiment of the present invention.

  The vegetable room 5 is provided with a vegetable room container 50 which is a storage container. The vegetable room 5 is partitioned by the following space, and the vegetable room container 50 is arranged in the vegetable room 5. That is, the rear surfaces of the refrigerator compartment doors 2a and 2b where the door pocket 8 is not disposed, the upper surface of the partition wall 5a, the lower surfaces of the partition portions 4c and 4d with the chilled chamber 4, the heat insulating partition portion 5b, and the vegetable compartment A space surrounded by left and right storage chamber side walls 5c (see FIG. 10) in the vegetable compartment 5 is defined as a vegetable compartment 5.

  The vegetable compartment container 50 is placed and held on a base 60 described later. The user is configured to pull out the vegetable compartment container 50 together with the base 60 by placing a hand on the handle portion 51 of the base 60.

  As shown in FIG. 5, the shelf 3b that also serves as a partition between the refrigerator compartment 3 and the chilled compartment 4 is provided so as to approach the door pocket 8 in front of the chilled compartment 4 when the refrigerator compartment doors 2a and 2b are closed. ing. Further, between the chilled chamber 4 and the vegetable chamber 5, there is a partition 4c that is the bottom surface of the chilled chamber 4 below the chilled chamber container 4a, and a front of the vegetable chamber container 50 described later from the front end of the partition 4c. A partition portion 4d formed up to the upper portion is continuously provided. That is, the vegetable room 5 and the vegetable room container 50 are configured to protrude from the upper chilled room 4 and the chilled container 4a.

  The cold air in the refrigerator compartment 3 is difficult to flow into the chilled chamber container 4a by the shelf 3d and the door pocket 8. Further, the partition portion 4d and the bottom surface of the door pocket 8 make it difficult for cold air to flow into the vegetable compartment container 50. That is, by making it difficult for cold air in other rooms to enter the chilled room container 4a or the vegetable room container 50, it is possible to prevent the room temperature from decreasing or rising, and to manage the temperature appropriately. In addition, cold air flows directly into the chilled chamber 4 from a discharge port provided in a part of the refrigerator air cooler air duct 18R by the setting of the switching lever 4b.

  The cold air blown into the refrigerated chamber 3 and the chilled chamber 4 passes between the bottom surface of the chilled chamber container 4a and the upper surfaces of the partitions 4c and 4d, and from the chilled chamber cold air return duct 17R at the rear of the chilled chamber 4 and the vegetable chamber 5. Return to cooler chamber 10.

  The vegetable compartment 5 is configured to be indirectly cooled from above by return cold air passing between the bottom surface of the chilled chamber container 4a and the top surfaces of the partition portions 4c and 4d.

<Configuration of vegetable compartment container 50 (storage container) and base 60>
Next, the shape of the vegetable compartment container 50 (storage container) and the base 60 will be described with reference to FIGS. 6A to 9. FIG. 6A is a front view of the storage container of the refrigerator according to the first embodiment of the present invention. 6B is a right side view of the storage container of FIG. 6A. 6C is a rear perspective view of the storage container of FIG. 6A. FIG. 7 is a front perspective view of the base of the refrigerator according to the first embodiment of the present invention. FIG. 8 is a partial cross-sectional view of a state where the storage container is placed on the base of the refrigerator according to the first embodiment of the present invention. FIG. 9 is a partial cross-sectional view showing a different embodiment from FIG. 8 in a state in which the storage container is placed on the base.

  The storage container 50 has a handle recess 50 b formed along the handle 51 of the base 60. Accordingly, when the storage container 50a is placed on the base 60, the concave portion 50b and the convex portion 60b on the handle 51 side are fitted, so that the placement position of the storage container 50 is determined, and the concave portion 50b is positioned by the positioning of the storage container 50. It will also act as a means. Thus, by providing the handle 60 on the base 60, the left and right movements of the storage container 50 are suppressed, and the storage container 50 can be stably held.

  As shown in FIG. 6A, a pair of claw portions 50c protruding downward are provided on the upper surface of the recess 50b of the storage container 50. Furthermore, as shown in FIG. 7, a pair of recessed locking portions 60 c are provided on the left and right on the upper surface of the convex portion 60 b of the base 60. In this configuration, the claw portion 50 c of the storage container 50 is locked to the locking portion 60 c of the base 60, whereby the position of the storage container 50 with respect to the base 60 is regulated, and the storage container 50 is operated in accordance with the operation of the base 60. Also work together.

  Moreover, as shown to FIG. 6C, the convex part 52 is provided in the bottom face of the storage container 50, and it has an uneven | corrugated shape. Thereby, in a state where the storage container 50 is held on the base 60, the convex portion 52 forms a space between the bottom surface of the storage container 50 and the top surface of the base 60. By forming the air heat insulating layer in this space, the heat insulating effect in the storage container 50 is enhanced, and the storage container 50 and the base 60 have a role of making it difficult to transmit heat to each other. Therefore, it is possible to obtain a stable cold insulation characteristic in the vegetable compartment 4.

  Further, the storage container 50 of this embodiment has a configuration in which the lateral width dimension A is larger than the depth width dimension B. Therefore, in a storage container in which a large variety of stored items are generally stored, the longer the width than the depth, the better the visibility to the back, so the convenience is improved. Moreover, by setting it as such a structure, the space behind the vegetable compartment 5 can be utilized effectively, and the freedom degree of design can be improved. In the present embodiment, as shown in FIG. 5, a cold air blower fan 11 is arranged in the rear space of the vegetable compartment 5, and a heat insulating partition portion 5 b is further arranged between the vegetable compartment 5 and the cold air blower fan 11. Therefore, the heat insulation thickness of the heat insulation partition part 5b can be taken large. Thereby, the heat influence to the vegetable compartment 5 from the cooler room 10 can be reduced, and the temperature change of the vegetable compartment 5 can be suppressed.

  Next, the configuration of the base 60, particularly the shape and material will be described. 7 and 8, the base 60 includes a glass member 61 formed of a glass material and a resin member 62 formed of a resin material (for example, polyacetal) and combined so as to surround the end of the glass member 61. Has been.

  The resin member 62 includes a holding portion 63 arranged in an annular shape so as to cover a predetermined width of the upper surface of the end portion of the glass member 61, a side wall 64 that rises upward from the holding portion 63 and suppresses the front, rear, left, and right movement of the storage container 50; A slide portion 65 that slides in a rail 70 (details will be described later) provided in the front-rear direction outside the side wall 64 and provided on the refrigerator main body 1H side is integrally formed. The slide portion 65 is formed so as to protrude from the side wall 64 toward the side wall 5c of the refrigerator 1 (see FIGS. 8 and 10). Further, as shown in FIG. 8, the end of the glass member 61 is covered so that the base 60 is vertically sandwiched between the holding portion 63 of the resin member 62 and the end of the slide portion 65, and together with the holding portion 63, the storage container 50 a. Holding.

  Further, as shown in FIG. 7, the resin member 62 has base-side rollers (movable rollers) 67 as moving bodies at both rear ends (rear of the slide portion 65). The moving body 67 is not limited to a roller but may be a slider (see a base-side slider 67a in FIG. 14). Details will be described later.

  In the present embodiment, the vegetable compartment container 50 has a configuration in which the lateral width dimension A is larger than the depth width dimension B. The width dimension C of the base 60 is larger than the depth dimension D so as to match the size ratio of the vegetable compartment container 50.

  In the case of such a dimensional ratio, when the slide portions 65 provided at both ends of the base 60 are brought into contact with the rail 70 on the refrigerator main body 1H side, a bending force is generated toward the center of the base 60. At this time, this bending can be suppressed by forming a part including the vicinity of the center of the base 60 with a glass material having a higher bending rigidity than the resin.

  That is, the strength of the base 60 can be increased by molding the frame material of the base 60 with a resin, and forming a part of the bottom of the base 60 with a glass material, compared with a base molded with a resin or metal. By configuring the base 60 as described above, when the storage container 50 having a large load is molded only with resin, the base may be deformed by bending, but this can be suppressed. In addition, since the glass material is less expensive than resin or metal, the manufacturing cost can be reduced.

  In addition, in the bottom freezer type refrigerator as in the present embodiment, a cold air blowing fan is disposed on the back of the vegetable room, and the base 60 includes a softer resin than the glass material. Noise and vibrations from the motor can be absorbed, and a silent effect and an anti-vibration effect can be expected.

  Moreover, the part which the base 60 contacts with the structure (the storage container 50, the rail 70, etc.) of the refrigerator 1 is comprised with the resin member 62, and the glass member 61 is directly other than that by comprising the other part with the glass member 61. It prevents contact with the structure. Thereby, the glass member 61 is prevented from being damaged, the strength of the base 60 itself is secured, and the drawer-type storage container 50 can be enlarged.

  The glass member 61 may be a material transparent to visible light, or may be a translucent or opaque material. When a transparent or translucent material is used, the bottom surface partitioning the space of the storage container 50a can be seen through, so that the container space can be shown larger to the user.

  In the present embodiment, the outer frame of the glass member 61 is covered so as to be sandwiched between the holding portion 63 of the resin member 62 and the end portion of the rail portion 65, but this is not restrictive. For example, as shown in FIG. 9, the holding portion 63 may be deleted from the base 60 and the glass member 61 may be placed on the end portion of the rail portion 65. By setting it as such a structure, since the glass member 61 is only mounted in the resin member 62, it can be removed. Therefore, since the glass member 61 can be removed and washed, the cleaning property can be improved. Further, when cleaning, the base 60 can be carried separately by the resin member 62 and the glass member 61, so that the portability can be improved.

  Further, even when a liquid material such as juice or juice is attached to the base 60, the glass member 61 is not easily deteriorated by the components of the liquid material, so that the base member 60 is prevented from being easily bent and deformed due to a decrease in strength of the base 60 for a long time. it can. As a result, even if a large amount of items are stored in the storage container 50 and a large load is applied to the base 60, a smooth pull-out operation is possible.

<Rail configuration>
Next, the configuration of the rail will be described with reference to FIGS. 10, 11A, and 11B. FIG. 10 is a front partial cross-sectional view around the rail of the refrigerator according to the first embodiment of the present invention. FIG. 11A is a perspective view illustrating a state in which the storage container of the refrigerator according to Embodiment 1 of the present invention is pulled out. FIG. 11B is a perspective view illustrating a state in which the storage container of the refrigerator according to the first embodiment of the present invention is stored.

  The slide portion 65 has a substantially U-shaped receiving portion 66 that receives a storage chamber side roller 71 (fixed roller) which is a first support described later. On the other hand, a rail 70 is provided at the lower portion of the storage chamber side wall 5 c and guides the movable roller 67 attached to the slide portion 65 of the base 60. Thereby, the base side roller 67 (movable roller) fixed to the back both side surfaces of the base 60 which will be described later rotates in the front-rear direction as the vegetable compartment container 50 is put in and out.

  A storage chamber side roller 71 (fixed roller) is fixed to the front end portion of the rail 70, and the receiving portion 66 which is the lower surface of the slide portion 65 is rotated back and forth. On the other hand, base-side rollers 67 (movable rollers) are provided on both rear side surfaces of the base 60. The movable roller 67 rotates back and forth as indicated by a broken line in FIG. As a result, the base 60 can be pulled out.

  In the present embodiment, the base 60 is provided with a handle 60a, the height position of at least a part of the handle 60a, the first support 71 (the storage chamber side roller (fixed roller)), the rail 70, The height position of each sliding portion with the moving body 67 (base side roller (movable roller)) is set close to or the same as the height position of the bottom surface of the base 60. Thereby, the user can transmit the force for pulling out the vegetable compartment container 50 in the horizontal direction directly to the sliding portion of the vegetable compartment container 50, and the vegetable compartment container 50 can be pulled out with a small force.

  In the present embodiment, the rail 70 facing the slide portion 65 of the base 60 is formed so as to project outward with respect to the left-right direction of the refrigerator 1. And the concave rail 70 was formed in the front-back direction of the side wall 5c of the vegetable compartment 5, and it was set as the structure in which the slide part 65 of the base 60 is located in this. Therefore, the clearance (clearance) between the vegetable compartment container 50 and the left and right side walls 5c of the vegetable compartment 5 can be reduced. As a result, the dead space can be reduced and the volume of the storage container 50 can be increased.

<Structure of refrigerator compartment door>
Next, the relationship between the vegetable compartment container 50 and the refrigerator compartment doors 2a and 2b when the vegetable compartment container 50 is pulled out will be described with reference to FIGS. 12, 13A, and 13B. 12A and 12B relate to the first embodiment of the present invention, in which FIG. 12A is a perspective view of the refrigerator compartment door seen from the side opposite to the hinge, and FIG. 12B is a perspective view of the refrigerator compartment door seen from the side on the hinge side. FIG. FIG. 13A is a front perspective view of the vegetable compartment storage container with the refrigeration compartment door opened 90 degrees according to the first embodiment of the present invention. FIG. 13B is a front perspective view of a state in which the storage container of the vegetable compartment is housed in a state where the refrigerator compartment door is opened 90 degrees according to the first embodiment of the present invention.

  A rear pocket located on the storage room side of the refrigerator compartment door 2b has a door pocket 8 that can accommodate drinks and small items. Further, on the rear surface of the refrigerator compartment door 2b, projecting portions 101 and 102 are provided on the left and right sides of the rear surface so as to project toward the storage chamber side. The protrusions 101 and 102 function as a door liner, and the position of the door pocket 8 is defined when the door pocket 8 is locked to a locking portion (not shown) provided in the protrusions 101 and 102.

  In addition, the protrusion part 101 is provided in the up-down direction of the side rotated to the near side when the refrigerator compartment door 2b is opened, and the protrusion part 102 is provided in the up-down direction on the hinge part 104 side. Yes. And as shown in FIG.12 (b), the protrusion part 102 is not provided in the height position of the door back surface part 103 of the position facing the vegetable chamber container 50 pulled out at least. Moreover, the position of the door pocket 8 is provided in the position higher than the door back surface part 103, and when pulling out the vegetable compartment container 50, it is installed in the position where the door pocket 8 does not interfere. In addition, the refrigerator compartment door 2a is also configured such that the protruding portion 102 and the door pocket 8 are not provided at the height position of the door back surface portion 103, similarly to the refrigerator compartment door 2b.

  By adopting a configuration in which the protruding portion 102 is not provided on the door rear face portion 103 facing the vegetable compartment container 50, the vegetable compartment container is opened in the state where the refrigerator compartment doors 2a and 2b are opened 90 degrees as shown in FIGS. 13A and 13B. There is nothing in front of 50, and the amount of drawers of the vegetable compartment container 50 can be increased. Therefore, even if the refrigerator compartment doors 2a and 2b are not opened over the range exceeding the projected area of the refrigerator 1 (even if the refrigerator compartment doors 2a and 2b are not opened beyond the horizontal dimension of the refrigerator main body 1H), the vegetables The chamber container 50 can be pulled out.

  Moreover, although it was set as the structure which does not provide the protrusion part 102 in the position of the door back surface part 103 at the hinge part 104 side, the protrusion part 101 side is similarly set as the structure which does not provide the protrusion part 101 in the position facing the vegetable compartment container 50. Also good. Thereby, since interference of the protrusion part 101 is lose | eliminated when pulling out the vegetable compartment container 50, it can be set as the structure which pulls out the vegetable compartment container 50 to the near side.

  As described above, there is no obstacle such as walls or furniture on the left and right sides of the refrigerator compartment doors 2a and 2b by providing the projections 101 and 102 on the rear surfaces of the refrigerator compartment doors 2a and 2b with no protrusions. Even if it is, the opening operation of the refrigerator compartment doors 2a and 2b is possible, and the arrangement | positioning according to the layout of each user's living environment is attained. Moreover, since it is not necessary to open the refrigerator compartment doors 2a and 2b largely, cold air is hard to leak and there is an energy saving effect.

  Further, in the case where the protruding portion 102 is not provided at the position of the door back surface portion 103 on the hinge portion 104 side, the protruding portion 101 on the side opposite to the hinge portion 104 serves as a stopper when the vegetable compartment container 50 is pulled out. The vegetable compartment container 50 can be stopped so as not to protrude too far forward. Therefore, the vegetable compartment container 50 can be prevented from dropping by unexpectedly pulling out the vegetable compartment container 50 excessively.

  In the present embodiment, when the vegetable compartment container 50 is pulled out, at least the rear surface of the door at the position facing the vegetable compartment container 50 to be pulled out is not provided with a convex part. Absent. For example, it is good also as a structure which provides a convex part of the height which does not interfere with the vegetable compartment container 50, even if it is a structure provided with a convex part partially. Moreover, although the vegetable compartment container 50 was demonstrated in the present Example, if it is a drawer-type storage container 50, a convex part will not be partially provided in the back of the door of the position which opposes it, or it will interfere with the storage container 50. What is necessary is just to set it as the structure provided with the convex part of the height which does not. In addition, although description was abbreviate | omitted about the refrigerator compartment door 2a, it is set as the structure similar to the refrigerator compartment door 2b.

  In this embodiment, the refrigeration room doors 2a and 2b are configured to open 90 degrees. However, the present invention is not limited to this. For example, the refrigeration is performed so that the handle 51 for pulling out the vegetable compartment container 50 is handled. Even when the chamber doors 2a and 2b are opened (for example, about 30 degrees), the vegetable chamber container 50 is pulled out so as not to interfere with convex portions such as door liners provided on the back side of the refrigerator doors 2a and 2b. be able to.

  In addition, in a present Example, the protrusion part 102 is not provided in the hinge part 104 side of the part facing the vegetable compartment container 50 located in the lowest part behind refrigerator compartment door 2a, 2b, or it does not interfere with the vegetable compartment container 50. Although the structure which provides the protrusion part 102 of height was demonstrated, it does not restrict to this. If the storage container 50 having a drawer structure is provided in a double-opening (French door) or single-opening (single door) door, a convex portion is not provided facing the position of the storage container 50, or What is necessary is just to set it as the structure which provides the convex part of the height which does not interfere with the storage container 50. FIG. Moreover, you may provide the recessed part and notch of the grade which do not interfere with the storage container 50. FIG.

(Example 2)
Next, a second embodiment of the present invention will be described with reference to FIGS. FIG. 14 relates to the first embodiment of the present invention, in which (a) shows a state in which the storage container is stored in the vegetable room, (b) shows a transient state in which the storage container is pulled out, and (c) shows a state in which the storage container is pulled out. FIG. FIG. 15 is a partial perspective view illustrating the position of the second support portion according to the second embodiment of the invention. FIG. 16 is a partial perspective view showing a state where the storage container of FIG. 15 is removed. FIG. 17 is an enlarged perspective view of a main part of the base according to the second embodiment of the present invention. FIG. 18 is a partial vertical cross-sectional view illustrating a second support portion according to Embodiment 2 of the present invention. FIG. 19 is a diagram for explaining a mounting configuration of the first support portion according to the second embodiment of the present invention.

  The difference from the first embodiment is that the base side roller 67 is a slider (moving body 67a). Further, the second support 72 is provided in front of the first support 71. In addition, about the structure similar to Example 1, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  In FIG. 14, the base 60 is composed of the glass member 61 and the resin member 62 as described above. Therefore, the bottom surface of the base 60 is rigid with the glass member 61 and does not bend like a resin. When the hand 60 is applied to the handle 51 of the base 60 and a forward force is applied, the storage container 50 is pulled out together with the base 60.

  The storage container 50a is integrally formed of a synthetic resin material, and has a configuration in which the width dimension A is larger than the depth dimension B (see FIG. 6C). For this reason, when a lot of stored items such as vegetables are put into the storage container 50, the bottom of the storage container 50 bends downward by 40 to 50 mm in the width direction. The glass member 61 on the base 60 side supports this bending. That is, the glass member 61 supports the bottom portion of the storage container 50 in a bent state, thereby suppressing the storage container 50 from being bent outward by 40 to 50 mm to 5 mm or less (corresponding to the bending amount of the glass member 61).

  As shown in FIG. 14, the moving body 67a (base-side slider) has an arc shape that protrudes downward. The second support 72 (storage chamber side slider) has a center of gravity forward when the vegetable compartment container 50 and the base 60 are pulled out of the vegetable compartment 5 like the first support 71 (fixed roller). Prevent moving and falling forward. The upper end position of the second support 72 is substantially the same as that of the first support 71.

  Furthermore, as shown in FIG. 15, the position where the second support 72 is provided is on the partition wall 5a (the bottom wall of the storage chamber), forward of the first support 71, and the opening edge of the storage chamber. The front side is close to 73 (for example, 20 to 40 mm behind the storage chamber opening edge 73). The partition wall 5a provided with the second support 72 is filled with a foam heat insulating material, and the mounting strength of the second support 72 to the partition wall 5a is ensured. That is, when the load of the vegetable compartment container 50 and the stored item is applied to the second support 72 and the first support 71, the height at the position of the second support 72 and the first support 71 changes. Make sure to keep the strength.

<Drawing operation of vegetable compartment container 50>
Next, the operation | movement at the time of pulling out the vegetable compartment container 50 from the vegetable compartment 5 is demonstrated.

  First, in FIG. 14A, approximately 20 to 40 kg of vegetables or the like can be stored in the storage container 50. Further, the storage container 50 and the base 60 are configured such that a protrusion 60b (see FIG. 7) on the base 60 side that protrudes toward the storage container 50 is detachably engaged with a recess 50b (see FIG. 6C) on the storage container 50 side. Therefore, they are combined so as to be integrated.

  The handle 51 is provided near the lower surface of the base 60 in a range where the user's hand can be put. That is, at least a part of the handle portion 51, the first support 71 (fixed roller) and rail 70 on the vegetable compartment 5 side, and the moving body 67 a (base side slider) on the base 60 side are attached to the base 60. It is designed to be close to or the same as the height position. As a result, the storage volume of the storage container 50 can be increased, the pulling force can be efficiently transmitted to the sliding portion, and the force required for pulling can be reduced.

  Next, in FIG. 14B and FIG. 15, the second support 72 (storage chamber side slider) is close to the storage chamber opening edge 73 of the partition wall 5a (as an example, 20 to 40 mm from the storage chamber opening edge 73). It is provided in the position. The second support 72 does not contact the vegetable compartment container 50 in a state where the vegetable compartment container 50 is stored behind the vegetable compartment 5 (the state of FIG. 14A), and the vegetable compartment container 50 is predetermined forward. After the distance is drawn, the base 60 is contacted. Thus, the vegetable compartment container 50 is supported from below so that the vegetable compartment container 50 is held horizontally even when it is pulled out.

  Next, in FIG.14 (c), when the vegetable compartment container 50 is pulled out to the forefront from the state of FIG.14 (b), most of the vegetable compartment container 50 will be located in the near side rather than the rail 70, and the base 60 will be shown. Only the rear part of the side slide part 65 is located in the rail 70.

  In this state, a downward load F1 is applied to the front end of the vegetable compartment container 50, and the second support 72 (storage chamber side slider) is used as a fulcrum to contact the rail 70 and the moving body 67a (base side slider) on the base 60 side. An upward force acts at the contact P. The reason that the second support 72 is a fulcrum is that there is a slight gap in the rail 70 for sliding the moving body 67a.

  Here, in the case of the conventional general refrigerator, the 1st support body 71 becomes a fulcrum. On the other hand, in this embodiment, the second support 72 is provided in front of the first support 71. From this, the distance L1 from the contact part (P part) of the moving body 67a and the rail 70 to the contact part of the second support 72 and the base 60, and the first support 71 and the base 60 from the P part. When the distance L2 to the contact portion is set, the force applied to the action point P can be reduced by L2 / L1. With this configuration, it is possible to reduce the need to increase the strength of the first support 71, the moving body 67a, and the rail 70 more than necessary.

  In the present embodiment, the bottom of the base 60 is supported by the second support 72 provided near the storage chamber opening edge 73 of the partition wall 5a, thereby assisting in preventing the vegetable chamber container 50 from falling forward.

<Configuration of first support 71 and rail 70>
Next, in FIGS. 16, 17, 18, and 19, the relationship between the first support 71 (fixed roller) and the rail 70 and the attachment / detachment configuration of the first support 71 will be described.

  In FIG. 16, the 1st support body 71 (fixed roller) is provided in the open part 70a vicinity of the rail 70 front end provided in the storage chamber side wall 5c.

  17 and 18, reference numeral 74 denotes an inclined portion provided on the front lower surface of the slide portion 65. The inclined portion 74 has an inclination that becomes lower on the rear side. When the vegetable compartment container 50 is accommodated from the state of FIG. 14B or FIG. 14C to the state of FIG. 14A, the inclined portion 74 located on the fixed roller 71 is caused to function as a drop-in portion. In other words, at the contact position on the inclined portion 74 and the fixed roller 71, the weight of the vegetable compartment container 50 is urged in the direction of moving backward, thereby fulfilling the function of a closer that automatically closes. Thereby, storage operation is assisted so that vegetable compartment container 50 may not stop in the middle of storage.

  Next, 75 is a recess provided in the partition wall 5a. The concave portion 75 is formed with a depth at which approximately ½ of the diameter of the fixed roller 71 provided on the storage chamber side wall 5c is positioned in the partition wall 5a in the vertical direction. In the case where the entire diameter of the fixed roller 71 is positioned above the partition wall 5a, the bottom position of the vegetable compartment container 50 is increased by the size, and the storage capacity of the vegetable compartment container 50 is reduced. Therefore, at least the upper end portion where the fixed roller 71 is in contact with the bottom surface of the base 60 is configured to be exposed above the partition wall 5a. With this configuration, the fixed roller 71 comes into contact with the base 60 and assists the back-and-forth movement, and the bottom surface position of the vegetable compartment container 50 can be further lowered to increase the storage volume.

  Next, with reference to FIG. 19, the attachment / detachment of the fixed roller 71 will be described. The attachment and removal of the fixed roller 71 fixed to the side wall of the vegetable compartment 5 is performed by removing the vegetable compartment container 50 from the vegetable compartment 5 or moving the vegetable compartment container 50 backward from the fixed roller 71 (cooler compartment 10 side). It is done in the state. The fixed roller 71 is fixed to the storage chamber side wall 5 c by fastening means such as a screw 76. Moreover, the fixed roller 71 is attached so that about 1/2 of the diameter is positioned in the partition wall 5a in the vertical direction. This configuration makes it difficult to turn the screw 76 with a tool (for example, a driver 77) shown in FIG.

  Therefore, in the present embodiment, the operation using a tool is facilitated by using the recess 75. That is, the recess 75 facilitates the attaching / detaching operation of the fastening means such as the screw 76 for fixing the fixing roller 71 to the storage chamber side wall 5c in addition to enabling the fixing roller 71 to rotate. More specifically, by forming the recess 75, the tip of the tool can reach the screw 76 even if the tool 77 is tilted sideways along the partition wall 5a as shown in FIG.

  The recess 75 is formed to expand in the width direction (left-right direction) of the partition wall 5a, and has an inclined surface 75a that gradually increases at a predetermined distance from the storage chamber side wall 5c. The inclined surface 75a is formed at an angle sufficient to insert and operate the tip of the tool 77 in the screw hole of the head of the screw 76 with the handle portion of the tool 77 inclined at a predetermined angle from the horizontal direction. In addition, since the vegetable compartment container 50 is always located on the recessed part 75, it is hard to be visually recognized by a user and an external appearance design property is not impaired.

  Since the present embodiment has the above-described configuration, the following effects can be obtained.

  First, a storage chamber 3 formed in the refrigerator body 1, doors 2a and 2b for opening and closing the storage chamber 3, a storage container 50 disposed in the storage chamber 3, a base 60 for mounting the storage container 50, A handle 51 at the front of the base 60, a rail 70 provided on the inner surface of the storage chamber 3, a moving body 67 a (67) that is provided at the rear of the base 60 and moves on the rail 70, And a first support 71 that is provided in front of the lower part and supports the base 60 so as to be movable in the front-rear direction, and each of the first support 71, the rail 70, and the movable body 67a (67) slides. The height position of the portion and the height position of at least a part of the handle portion 51 are set close to or the same as the height position of the bottom surface of the base 60.

  As a result, the dimensions of the storage container can be increased, and when the storage container is pulled out, the sliding part and the handle part are located on substantially the same line. With this, the storage container can be pulled out.

  In addition, the second support body 72 includes a second support body 72 provided in front of the first support body 71. When the moving body 67 is located on the rear end side of the rail 70, the second support body 72 When the handle portion 51 is operated and the moving body 67 moves a predetermined distance from the rear end side of the rail 70 to the front from the front end, by supporting the base 60, the storage container 50 is separated from the front portion. It moves in the front-rear direction so that the height position of the rear part does not change.

  Accordingly, even when the storage container 50 moves forward and most of the storage container 50 is positioned in front of the rail 70, the storage container 50 is tilted forward by the second support 72 supporting the base 60. This can be reduced and a smooth drawer operation can be achieved.

  The base 60 is composed of a glass member 61 and a resin member 62 at the end of the glass member 61, and the moving body 67 a is formed on the resin member 62, and the first support body 71 and the second support body 71 are formed. The support 72 supports the resin member 62.

  Thereby, even if a storage container is a resin molded product, since there is a rigid base at the bottom, bending is reduced.

  The moving body 67a (67) is a roller or a slider, and the first support 71 is a roller. Thereby, the sliding movement of the storage container becomes smooth.

  Moreover, the 2nd support body 72 is a slider, Comprising: It provides in the bottom wall (partition wall 5a) of the storage chamber 3 which has a foam heat insulating material inside.

  Thereby, rigidity can be improved by dispersing the load acting on the second support 72 on the bottom wall of the storage chamber 3.

  Further, the bottom wall (partition wall 5a) adjacent to the storage chamber side wall 5c is formed with a concave portion 75 having a predetermined width in the left-right direction, and the first support 71 is configured near the storage image chamber side wall 5c of the concave portion 75. The roller which performs is arrange | positioned, and the half of the height dimension of a roller is located in the recessed part 75. FIG.

  Thereby, while the dimension between the base 60 and the partition wall 5a can be made small, the attachment / detachment of the 1st support body 71 becomes easy, without using a special tool.

  Further, the handle portion 51 of the base 60 protruding toward the storage container 50 is detachably engaged with the recess 50b on the storage container 50 side. Thereby, without requiring a special part for integrating the storage container 50 and the base 60, the handle portion 51 can be improved in strength by having a double structure.
