Description

  The present invention relates to a refrigerator.

  In order to provide one room of a refrigerator having a so-called drawer-type door, for example, a freezing room that can efficiently cool the room, the lower end of the protrusion provided on the lower surface of the main body is attached to the container. In contact with the front end, the upper space of the container and the heat intrusion space formed by the upper back of the drawer door and the main body are shielded, and a heat insulating member is disposed between the drawer door and the container. Thus, a refrigerator has been proposed that shields the space in front of the container and the heat intrusion space, and blocks the cool air flowing from the upper front of the container through the vent hole to the front from the heat that has entered the heat intrusion space ( For example, see Patent Document 1).

  In this refrigerator, the gasket attached to the peripheral edge of the door and the partition wall come into contact with the door closed, and the convex part of the drawer-type door and the front wall extension of the container are brought into contact with each other through a sealing material. This prevents the cold air in the freezer compartment from flowing into the front space of the container.

  Further, plate-like ribs hang from the lower surface of the partition wall over the entire width of the container. This rib is in contact with the front wall extension of the container, so that the cold air in the freezer compartment is prevented from flowing from the upper part of the container to the gasket side.

In addition, the container has a margin in the front-rear direction so that it can be removed from the container support and cleaned, but the flange portion and the sealing material are sufficiently in contact with each other even when the container is located at the rearmost position. .
JP-A-9-79728

  However, in the refrigerator described in Patent Document 1, the rib of the partition wall and the front wall extending portion of the container do not come into contact with each other when the container has a margin in the front-rear direction or before the door is completely closed. There is a problem that the rib and the extension part come into contact with each other, which causes the door not to close.

  In the case of a refrigerator having a plurality of containers in one room, the lower container has a mechanism for sliding the upper container, and the upper container slides backward after the door is pulled out, so that the food in the lower container Can be taken. In such a case, in the method in which the extension part and the door convex part are brought into contact with each other via the sealing material, the upper container is sealed to the door convex part because of the slide mechanism when trying to make the upper container contact with the door convex part. If the material is attached, the upper container becomes lower than a predetermined position due to the deterioration of the drawer operability or the load of food, and the door protrusion and the upper container may hit from the front. In addition, in order to bring the lower container into contact with the convex portion of the door, it is necessary to enlarge the lower container in the height direction, and there is a problem that the cost is increased and the cleaning property of the container is deteriorated.

  The present invention has been made to solve the above-described problems, and an object thereof is to provide a refrigerator capable of suppressing leakage of cold air to the outside at low cost and without deteriorating door drawer operability. And

The refrigerator according to the present invention includes a main body,
A storage chamber formed by partitioning the inside of the main body with a partition wall, and having a front opening,
A drawer type that opens and closes the front opening of the storage chamber, has a door inner plate and a door outer plate, is filled with a heat insulating material between the door inner plate and the door outer plate, and can slide back and forth. Door,
A gasket having fins provided over substantially the entire circumference of the outer peripheral edge of the door inner plate of the drawer-type door;
It is attached to the lower surface of the partition wall along the opening edge of the partition wall, and includes a packing with which the soft portion comes into contact with the fin of the gasket in a state where the drawer type door is closed. .

  In the refrigerator according to the present invention, in the state where the drawer door is closed, the fins of the gasket provided over substantially the entire circumference of the outer peripheral edge of the door inner plate of the drawer door are formed on the lower surface of the partition wall on the opening edge of the partition wall. Attached to the soft part of the packing that is installed along the side to be pushed into the freezer compartment side to prevent cold air in the storage compartment from flowing into the gasket side, contributing to energy savings without deteriorating the drawer operability It is possible to provide a refrigerator having a structure.

  FIG. 4 is a view showing a comparative example, and is an enlarged view of a main part in the vicinity of a freezer compartment door 2 d of a general refrigerator 100.

  An overall configuration of an example of the refrigerator 100 will be described with reference to FIGS. 1 and 2. The refrigerator 100 is formed by filling a heat insulating material 1c between a steel plate outer box 1a and a resin inner box 1b, and has a box-shaped main body 1 (heat insulating box) having an opening with one surface (front surface) opened. Body). The interior of the main body 1 is partitioned into a plurality of chambers by partition walls.

  The refrigerator 100 shown in FIGS. 1 and 2 is an example that is partitioned into five rooms. The front surfaces of the five chambers are open, and a door described later is attached to the front opening. A refrigeration room 6 is formed at the top, an ice making room 7 at the center left side, a switching room at the right side of the ice making room 7, a freezing room 9 below the ice making room 7 and the switching room, and a vegetable room 8 below the freezing room 9. In this specification, left and right are defined as left and right when the refrigerator 100 is viewed from the front. In FIG. 2, the switching room is not visible. In this specification, an ice making room 7, a switching room, a freezing room 9, and a vegetable room 8 having a drawer-type door are defined as an example of a storage room.

  A partition wall 10 partitions the refrigerator compartment 6 from the ice making chamber 7 and the switching chamber.

  The ice making chamber 7 and the switching chamber and the freezing chamber 9 are partitioned by a partition wall 12.

  The freezer compartment 9 and the vegetable compartment 8 are partitioned by a partition wall 13.

  The refrigerating room door 2a of the refrigerating room 6 located at the upper part of the refrigerator 100 is a rotary door and is a double-open door separated into left and right refrigerating room left doors 2a-1 and 2a-2.

  The ice making room door 2b of the ice making room 7 located on the left side under the refrigerator compartment 6 is a drawer-type door.

  The switching chamber door 2c located on the right side of the ice making chamber 7 is a drawer-type door.

  The freezer compartment door 2d of the freezer compartment 9 located below the ice making room 7 and the switching room is a drawer-type door.

  The vegetable compartment door 2e of the vegetable compartment 8 located under the freezer compartment 9 is a drawer-type door.

  The ice making chamber door 2b of the ice making chamber 7 is provided with a container support 20a (a steel plate frame) for installing the container 50a on the back surface of the ice making chamber door 2b.

  A container support 20b (a steel plate frame) for installing the container 50c is attached to the freezer compartment door 2d of the freezer compartment 9 on the back surface of the freezer compartment door 2d. Further, a container 50b having a shorter depth than the container 50c is placed on the container 50c. The container 50b can slide back and forth on the container 50c.

  To the vegetable compartment door 2e of the vegetable compartment 8, a container support 20c (a steel plate frame) for attaching the container 50d is attached to the back of the vegetable compartment door 2e.

  The refrigerator 100 generates cold air that cools each room (the refrigeration room 6, the ice making room 7, the switching room, the freezing room 9, and the vegetable room 8) by a refrigeration cycle using a compressor (not shown). On the back side of the refrigerator 100, a cooler chamber (not shown) is provided inside the inner box 1b, and cold air is generated in the cooler chamber. In an evaporator (not shown) of the refrigeration cycle provided in the cooler chamber, cold air is generated by heat exchange between the refrigerant and air. At this time, moisture in the air condenses in the evaporator and eventually becomes frost. In order to maintain the performance of the evaporator, the frost adhering to the evaporator is periodically melted using, for example, an electric heater, and stored in an evaporating dish (not shown). For example, the defrost water stored in the evaporating dish is heated and evaporated by a condenser of a refrigeration cycle.

  Although the present embodiment provides a refrigerator 100 that can suppress the leakage of cold air to the outside at low cost and without deteriorating the door pull-out operability, first, FIG. As for the comparative example shown in the enlarged view in the vicinity of the freezer compartment door 2d), the seal of the freezer compartment door 2d in the freezer compartment 9 (prevention of leakage of cold air to the outside) will be described.

  In the general refrigerator 100 shown in FIG. 4, the gasket 21 in which the magnet 22 was inserted is attached to the back periphery of the freezer compartment door 2d. A horizontal partition plate 11 is attached to the opening edge of the freezer compartment 9. The gasket 21 and the partition plate 11 are in contact with each other when the freezer compartment door 2d is closed, thereby preventing the cold air in the freezer compartment 9 from leaking to the outside.

  Further, the protrusion 70 of the drawer-type freezer compartment door 2d (formed on the inner plate of the freezer compartment door 2d and formed in the left-right direction when viewed from the front of the refrigerator 100) and the flange portion 50c-2 of the container 50c are provided. By abutting through the sealing material 60, the cold air in the freezer compartment 9 is prevented from flowing into the front space 52 of the container 50c.

  Further, a plate-like rib 16 hangs down from the lower surface of the partition wall 12 over the entire width of the container 50c (left and right direction when viewed from the front of the refrigerator 100). This rib 16 is in contact with the front wall extension 50c-1 of the container 50c to prevent the cold air in the freezer compartment 9 from flowing from the upper part of the container to the front space 52 on the gasket 21 side.

  Further, the container 50c is provided with a margin in the front-rear direction so that it can be removed from the container support 20b and cleaned, but the flange portion 50c-2 and the sealing material 60 are provided even when the container 50c is located at the rearmost position. It is the structure which contact | abuts enough so that the leakage of cold air can be suppressed.

  However, the rib 16 of the partition wall 12 and the front wall extension 50c-1 of the container 50c do not contact if the container 50c has a margin in the front-rear direction, or the rib 16 before the freezer compartment door 2d is completely closed. And the front wall extending part 50c-1 come into contact with each other, and there is a problem that causes the freezer compartment door 2d not to be closed.

  Further, as shown in FIG. 2, in the case of the refrigerator 100 having a plurality of containers (the lower container 50c and the upper container 50b) in the freezer compartment 9, the upper container 50b has a mechanism for sliding on the lower container 50c, After pulling out the freezer compartment door 2d, the upper container 50b is slid rearward so that the food in the lower container 50c can be taken.

  In such a case, in the method in which the flange portion 50c-2 and the convex portion 70 of the freezer compartment door 2d are brought into contact with each other via the sealing material 60, a slide mechanism is used when the upper container 50b is brought into contact with the convex portion 70. For this reason, if the sealing material 60 is attached to the convex portion 70, the drawer operability is deteriorated. Alternatively, the upper container 50b may be lower than a predetermined position due to a load of food, and the convex portion 70 and the upper container 50b may hit from the front.

  Further, in order to bring the lower container 50c into contact with the convex portion 70, it is necessary to enlarge the lower container 50c in the height direction, resulting in an increase in cost and a deterioration in the cleanability of the container 50c. It was.

  With reference to FIG. 3, the seal (prevention of leakage of cold air to the outside) of the freezer compartment door 2d in the freezer compartment 9 of the present embodiment will be described.

  The freezer compartment door 2 d includes a door inner plate 80 and a door outer plate 81. A heat insulating material 82 is filled between the door inner plate 80 and the door outer plate 81 to suppress heat intrusion from the outside of the refrigerator 100. The material of the door inner plate 80 is ABS resin (acrylonitrile, butadiene, styrene copolymer synthetic resin).

  The door inner plate 80 has a convex portion 70 extending left and right when viewed from the front of the refrigerator 100. This convex part 70 protrudes to the freezer compartment 9 side. The protrusion 70 protrudes toward the freezer compartment 9, thereby increasing the thickness of the heat insulating material 82. The larger the dimension of the convex portion 70 that protrudes into the freezer compartment 9, the thicker the heat insulating material 82, and the better the heat insulation performance of the freezer compartment door 2d.

  The packing 90 is attached to the lower surface of the partition wall 12 along the opening edge of the partition wall 12 over the entire width (left and right direction when viewed from the front of the refrigerator 100).

  As shown in FIG. 3, the packing 90 includes an attachment portion 90 b attached to the partition wall 12 and a plurality of fins 90 a formed so as to hang downward from the attachment portion 90 b. The plurality of fins 90 a are formed in substantially the entire width of the packing 90. In the example shown in FIG. 3, the packing 90 includes three fins 90a.

  The material of the attachment portion 90b of the packing 90 is hard PVC (polyvinyl chloride), and the material of the fin 90a is soft PVC. Thus, the fin 90a is comprised by soft resin (soft part) compared with the attachment part 90b.

  A recess 80a is provided on the outer peripheral edge of the door inner plate 80 over the entire periphery. The gasket 21 is attached to the recess 80a. The material of the gasket 21 is, for example, PVC.

  The gasket 21 is provided with a plurality of fins 21a. These fins 21a and the door inner plate 80 are in contact with each other, thereby creating an air heat insulation layer and improving heat insulation performance.

  With the freezer compartment door 2d closed, any one of the fins 21a of the packing 90 (in the example of FIG. 3, the central fin 21a among the three fins 21a) is protruded from the door inner plate 80. It abuts on the part 70 in a form pushed behind the freezer compartment 9.

  Thereby, the cold air in the freezer compartment 9 is prevented from flowing into the gasket 21 side.

  Since the fin 90a of the packing 90 is made of a soft resin, when the fin 90a of the packing 90 is pushed rearward of the freezer compartment 9 by the convex portion 70 of the door inner plate 80, there is no resistance and abuts the convex portion 70. Thus, the freezer compartment door 2d is closed with the gasket 21 in contact with the partition plate 11 of the partition wall 12 properly.

  In addition, when the protrusion 90 of the door inner plate 80 pushes the fin 90a of the packing 90 to the rear of the freezer compartment 9, the protrusion 70 of the door inner plate 80 is caused by the mounting variation of the packing 90 and the assembly variation of the freezer compartment door 2d. And the packing 90 can be prevented from coming into contact.

  The gasket 21 is provided with a bag-like portion 21 a-1 on a plurality of fins 21 a closest to the freezer compartment along the entire circumference of the opening edge of the freezer compartment 9.

  In the state where the freezer compartment door 2d is closed, the fin 90a (one piece closest to the freezer compartment door 2d side) of the packing 90 is brought into contact with the bag-like portion 21a-1 so as to be pushed into the freezer compartment side.

  Thereby, the cold air in the freezer compartment 9 is prevented from flowing into the gasket 21 side.

  Therefore, it is possible to provide a refrigerator having a structure that contributes to energy saving without causing deterioration of the drawer operability.

  In the above description, the freezer compartment door 2d is taken as an example, but this embodiment can be applied to any drawer type door such as the ice making compartment door 2b, the switching compartment door 2c, the vegetable compartment door 2e, and the like.

  As described above, according to the present embodiment, any one of the fins 21a of the packing 90 is placed on the convex portion 70 of the door inner plate 80 with the freezer compartment door 2d closed. The cold air in the freezer compartment 9 is prevented from flowing into the gasket 21 side.

  Moreover, since the fin 90a of the packing 90 is made of soft PVC resin, when the fin 90a of the packing 90 is pushed rearward of the freezer compartment 9 by the convex portion 70 of the door inner plate 80, there is no resistance and the convex portion 70 By abutting, the freezer compartment door 2d is properly closed with the gasket 21 abutting against the partition plate 11 of the partition wall 12.

  In addition, when the protrusion 90 of the door inner plate 80 pushes the fin 90a of the packing 90 to the rear of the freezer compartment 9, the protrusion 70 of the door inner plate 80 is caused by the mounting variation of the packing 90 and the assembly variation of the freezer compartment door 2d. It can be avoided that the packing 90 does not come into contact.

  Further, the gasket 21 is provided with a bag-like portion 21a-1 on a plurality of fins 21a closest to the freezer compartment along the entire circumference of the opening edge of the freezer compartment 9 and the freezer compartment door 2d is closed. 21a-1 makes contact with the fin 90a (one sheet closest to the freezer compartment door 2d) at the end of the packing 90 so that the cold air in the freezer compartment 9 flows into the gasket 21 side. To prevent. Therefore, it is possible to provide a refrigerator having a structure that contributes to energy saving without causing deterioration of the drawer operability.
