Description

  The present invention relates to a refrigerator.

  Patent document 1 is mentioned, for example in the refrigerator which made the space | interval dimension between the doors opened and closed right and left small. Patent Document 1 includes a rotary partition that forms a magnetized surface of adjacent left and right doors, and a hook-shaped portion of a door packing that seals a gap generated between the upper and lower end surfaces of the rotary partition and the main body. It is disclosed that the door is inclined when the door is opened and is deformed when the door is closed and is in close contact with the partition.

  In this way, the hook-shaped portion of the door packing is inclined toward the inner side when the door is opened, and when the door is closed, it is deformed and closely contacts the partition, so that the tip of the door packing hook protrudes from the end surface of the door side portion. It is described that the size is reduced, the amount of contact with the other is reduced, and damage to the door packing and permanent deformation are prevented.

  Further, in the above document 1, not only the gap between the rotary partition and the main body seat but also the upper part of the door packing extends from the upper end to the lower end to form a bowl-like part, and the bowl-like part increases the restoring force as an elastic body. In addition, the sealing performance is improved. Further, there is a description that the partial notch processing of the hook-shaped portion of the door packing can be omitted, and the workability is increased.

  Further, in Patent Document 2, a refrigerator having a band-like handle protruding from the outer surface of a door and opening and closing adjacent doors in a double door (opening and closing left and right) is adjacent to the handle portion of the band-like handle provided in each door. There is disclosed one in which a handle shape that narrows the gap between adjacent handles is formed in a range that does not interfere with the rotation trajectory of the bowl-shaped portion of each seal packing of the mating door. As a result, it is described that the apparent gap size is reduced.

Japanese Patent Laid-Open No. 04-302983 JP 07-218103 A

  The refrigerator of the said patent document 1 has proposed the structure which makes small the space | interval dimension of a door on either side. However, with this configuration, it cannot be said that the distance between the doors can be sufficiently reduced at the present time.

  That is, the hook-shaped portion of the door packing shown in Patent Document 1 is inclined to the inside of the cabinet when the door is opened, slides on the surface of the partition when the door is closed, and is deformed from the inclination to parallel to the surface of the partition. While sliding, close contact. However, in order to reduce the distance between the doors, there is a limit to the angle at which the hook-shaped portion of the door packing is inclined. Therefore, it is difficult to greatly reduce the distance between the doors by inclining the hook-shaped portion, and the hook-shaped portion of the door packing is rubbed and worn at the inclined portion. Due to this wear and other changes over time, the initial shape may not be maintained. Moreover, at present, it cannot be said that the distance between the left and right doors can be made sufficiently small.

  Furthermore, it is not a partial provision of the bowl-shaped part, but a proposal to extend from the upper end to the lower end of the door packing has also been proposed, but this also has an inclined bowl-shaped part as described above. When the door is closed, the tip of the bowl-shaped portion first comes into contact with the rotating partition. In this case, the saddle-like portion is in the full length in the up-and-down direction of the door packing, and the door is not completely closed by the repulsive force of the full length of the saddle-like portion, and may be in a half-open state (half-door state). .

  This is also true when the hook-shaped portion of the door packing contacts the adjacent door. Accordingly, the distance between the doors cannot be made sufficiently small.

  The refrigerator of the conventional document 2 is only apparently made small in the space | interval dimension between right and left doors, and cannot make the space | interval dimension between left and right doors small. Accordingly, when the distance between the doors that are opened and closed to the left and right is reduced, the rotating partition member that closes the gap between the doors may come into contact with the adjacent door. In this case, the hook-shaped portion of the door packing rubs when the door is opened and closed, and the hook-shaped portion may be cut at a place worn by the rubbing.

  In order to solve the above-described problems, the present invention is configured so that even if the distance between the doors that opens and closes to the left and right is reduced, the hook-shaped portion of the door packing is in sliding contact when the door is opened and closed, causing rubbing, damage, and rubbing noise. It aims at suppressing generation | occurrence | production of this.

  In order to achieve the above object, the present invention provides an upper and lower hinge fixed to a box, a first door provided on the left and right of the front opening of the box fixed by using the hinge as a rotation shaft, A second door, a door packing that is provided in each of the first door and the second door, and suppresses gas movement between the box and the periphery of the box, the first door, and the first door A rotary partition member provided on the first door so as to close a gap between the second door and the door so as to close a gap between upper and lower ends of the rotary partition member and the front opening of the box. And a refrigerator provided with a bowl-shaped portion provided in the packing, wherein the width dimension of the bowl-shaped portion of the second door is smaller than the width dimension of the upper portion of the bowl of the first door. .

  In addition, the flange-shaped portion of the first door has a large width dimension at both upper and lower end portions, and the flange-shaped portion of the second door has a width dimension that is substantially the same in height, A portion having a large width dimension of the hook-shaped portion of the first door overlaps with the hook-shaped portion of the second door at both ends.

  Further, the hook-like portion of the second door is a rotation locus that does not contact the first door.

  In addition, the rotation trajectory of the large width portion of the upper and lower end portions of the bowl-shaped portion of the first door is substantially the same as or larger than that of the rotary partition, and does not contact the end surface of the second door. And

  In addition, when the door closes the front opening of the box, the flange-shaped portion of the second door has a width dimension that does not contact the rotating partition member in a bent state. .

  The present invention can suppress the generation of rubbing, damage, and rubbing noise, even when the distance between the doors that opens and closes to the left and right is reduced, because the hook-shaped portion of the door packing is in sliding contact when the door is opened and closed. .

  Hereinafter, a refrigerator according to an embodiment of the present invention will be described with reference to the drawings.

It is a figure which shows the state which experimented when it tried to close simultaneously from an open state. That is, it shows that the hook-shaped portion of the door packing is kept in contact with the rotating partition member.

  FIG. 11 is a diagram of the embodiment, and is a diagram illustrating the state of the hook-shaped portion of the door packing when both doors are closed simultaneously as in FIG. 10. FIG. 12 is an explanatory diagram of the door on the side not provided with the rotating partition member. FIG. 13 is a diagram illustrating an overlapping state between the hook-shaped portion of the door packing illustrated in FIG. 12 and the hook-shaped portion of the door packing on the rotating partition member side. FIG. 14 is an enlarged explanatory view of the main part of FIG.

  1 to 4, reference numeral 1 denotes a refrigerator main body, which is provided with a refrigerator compartment 7, a first freezer compartment, a second freezer compartment, and a vegetable compartment from the top. The refrigerator compartment 7 is closed at the front opening edge by doors 2 and 3 provided in parallel in the left and right directions. The doors 2 and 3 are rotatably attached to the refrigerator main body 1 using upper hinges 4 and 5 and a lower hinge (not shown).

  A handle 6 is gripped by the user when the doors 2 and 3 are opened and closed. The doors 2 and 3 of the refrigerating room 7 are attached to the opening of the refrigerating room and are of a double door type that opens and closes left and right. In order to seal the gap between the left and right doors that open and close to the left and right, the door 2 is provided with a rotating partition member 8.

  The rotating partition member 8 is pivoted on a door inner plate 9 by a shaft 10 and has a guide (not shown) at its end. The guide of the rotating partition member 8 is guided to a guide member (not shown) provided on the main body side of the refrigerator, whereby the rotating partition member 8 rotates, and thereby the door packing (magnet packing) provided on the door 3. ) Magnetized surface.

  In this case, a gap necessary for rotating the rotary partition member 8 is provided between the upper and lower ends of the rotary partition member 8 and the main body constituting the refrigerator compartment 7. 11 and 12 are door packings provided on the doors 2 and 3, and the door packings 11 and 12 are attached to the four peripheral edges of the doors 2 and 3, and cold air leaks from between the box body and the door of the refrigerator main body 1. To prevent.

  Reference numerals 13 and 14 denote bowl-shaped portions provided on the door packings 11 and 12. The flanges 13 and 14 seal the gap. Therefore, the hook-shaped portions 13 and 14 are provided only on the side that contacts the rotary partition member 8 of the door packing. A indicates the center of the gap between the left and right doors 2 and 3. B shows the center of the rotation partition in the width direction. C shows the maximum rotation locus of the rotary partition.

  The width dimensions of the hook-shaped portions 13 and 14 in this embodiment were asymmetric. Moreover, the width dimensions W1 and W2 of the bowl-shaped portion 13 are set to W1> W2 as shown in FIGS. The dimensional difference between the widths of the hook-like portion 13 and the hook-like portion 14 in the example was confirmed when W2 was 1 mm smaller and 1.5 mm smaller. A dew prevention heater 15 is attached to the back surface of the front plate 17 of the rotary partition member 8. This dew prevention heater 15 holds the surface plate of the rotating partition member 8 at about 30 ° C. when the ambient temperature is 30 ° C.

  Further, when the rotating partition member 8 is exposed outside the refrigerator compartment 7 (so-called half door), the surface temperature of the surface plate 17 is warmed to about 40 ° C., and in some cases to about 60 ° C. It is assumed that Reference numeral 16 denotes a contact-preventing concave portion that prevents the hook-shaped portion 13 from coming into contact. This prevents the hook 13 from being damaged by friction, wear or the like. The contact preventing recess 16 is formed integrally with the door frame 18 when the door frame 18 constituting the door 3 is formed.

  The contact-preventing recess 16 is formed so as to avoid the rotation trajectory created by the point c of the door 2 and the rotation trajectory of the rotary partition member 8. That is, as shown in FIG. 2, when the dimensions (rotation trajectory) from the hinge 4a to the points a, b, and c are compared, the dimension (rotation trajectory) from the hinge 4a to the point c is the maximum.

  Therefore, the rotation locus drawn by the point c is absorbed by the contact preventing recess 16 formed on the door 3 side, and the distance L1 between the doors can be reduced accordingly.

  The interval dimension L1 in the case of FIG. 2 is naturally set to a dimension in which the maximum rotation locus portion of the door 2 does not contact the adjacent door. The distance L1 between the doors of the latest refrigerator is small to the limit. For example, about 6 mm or 6.5 mm is the smallest. This interval dimension L1 is considered to be an assembly minimum dimension because an error of about ± 1 mm occurs even if the assembly error is strictly controlled. As described above, the current distance dimension L1 has become extremely small. Therefore, it is difficult to reduce the distance dimension L1 beyond this. Further, when the distance L1 between the small doors is further reduced as described above, the hook-shaped portion strongly contacts or slides on other members, and damage to the hook-shaped portion becomes a problem.

  If the door thickness can be reduced to a fraction of the current thickness, it is easy to reduce the distance L1, but this is not possible in the last few years. is there. Therefore, the present invention has a configuration in which the distance L1 between the doors is reduced without reducing the thickness dimension of the door, or the hooked portion does not strongly contact or slide contact with other members. suggest.

  The rotating partition member 8 in FIG. 4 is set so as to draw the maximum rotation locus on the door 2 side. Therefore, the points a and b are within the rotation locus of the rotary partition member 8. And the rotation locus which the rotation partition member 8 draws is set so that it may be located in the approximate center of the space | interval dimension L1 dimension. Naturally, the hook-shaped portion 13 is located outside the rotation locus. Therefore, the hook-shaped portion 13 comes into contact with or slides on the door 3 side every time the door is opened and closed. However, it is flexible and will not damage other members.

  Next, the relationship between the interval dimension L1 and the rotation locus drawn by the rotating partition member 8 will be described with reference to FIG.

  The space | interval dimension L1 is so good that it is small in order to balance the appearance with the door space | interval dimension (gap dimension), such as a system kitchen installed so that a refrigerator may adjoin, and other kitchen storage furniture.

  However, since the refrigerator door requires heat insulation, the thickness dimension is significantly large. For this reason, the rotation locus is drawn so that the point c at the corner of the door approaches the adjacent door when the door is opened and closed. The contact preventing recess 16 is provided so as to absorb the rotation locus.

  Since the rotation locus drawn by the door becomes maximum near the center of the thickness of the door as shown in the figure, L1 may be minimized on the front side of the door.

  Next, the rotation locus drawn by the rotation partition member 8 will be described. The rotating partition member 8 shown in FIG. 4 is an example outside the rotation locus of the point c of the door 2.

  The reason for taking it out of the rotation trajectory of the point c is to make the rotating partition member 8 smaller and to enlarge the door pocket (not shown) as described above.

  A rotation locus drawn by the rotating partition member 8 is indicated by a one-dot chain line C. This alternate long and short dash line C generally passes near or in the center of the distance L1 between the left and right doors. Thereby, even if the door 2 and the door 3 are opened simultaneously, it can prevent that the rotation partition member 8 and the door 3 collide, and the door 2 and the door 3 cannot be opened and closed.

  Next, the hook-shaped parts 13 and 14 provided in the door packings 11 and 12 will be described with reference to FIGS.

  In FIG. 5, 2 is a door (left) and 3 is a door (right). Reference numeral 8 denotes a rotating partition member. In the figure, the width dimension W1 of the bowl-shaped part 13 attached to the door 2 side and the width dimension W2 of the bowl-shaped part 14 are asymmetric and made to have a relationship of W1> W2. The gap between the upper and lower ends of the rotary partition member 8 and the box constituting the refrigerator main body 1 is closed by the dimensional relationship between the bowl-shaped portions 13 and 14, and the room and the outside are blocked. The difference in width between the hook-like portion 13 and the hook-like portion 14 in the embodiment is confirmed by the fact that W2 is 1 mm smaller and 1.5 mm smaller. confirmed. In this case, the overlapping dimension of the bowl-shaped parts 13 and 14 is the same as that of the conventional product.

  By configuring the door packings 11 and 12 in this way, it is possible to improve the deformation of the bowl-shaped portions 13 and 14 and improve the sealing performance when the door is closed. That is, since the hook-shaped portion 13 rubs against the door 3 side as in the prior art, it generates a rubbing sound when worn or opened / closed, but the rubbing-shaped portion 14 side is shortened so that no rubbing noise is generated or a small rubbing sound.

  6 to 8, FIG. 6 is a cross-sectional view of the door packing 11 in which the flange 13 is integrally formed by extrusion molding or the like. This door packing 11 is comprised by flexible members, such as a vinyl chloride resin. The door packings 11 and 12 have a thickness of about 0.5 mm.

  And the collar-shaped part of the said door packing 11 is cut and deleted except the L2 dimension part, as shown in FIG.

  Note that the hook-shaped portions 13 are provided above and below the door packing 11 and correspond to both the upper and lower end portions of the rotary partition member 8.

  Further, the L2 dimension is set to about 50 mm to 100 mm, and even if the hook-shaped portion 13 contacts the door 3 on the other side when the door 2 is opened and closed, it does not become a large resistance (particularly the hook-shaped portion 13 is cooled and hardened). Is considered).

  FIG. 8 is a combination of the door packing 11 having the hook-like portion 13 made in the same manner as the door packing 11 having the hook-like portion 13 shown in FIG. That is, it is a view in which the hook-like portion 13 and the hook-like portion 14 are overlapped with each other in the W3 dimension. Usually, the overlap dimension W3 is set to about 3 mm to 5 mm. Further, the width dimensions W1 and W2 of the bowl-shaped portions 13 and 14 shown in this figure are set so that W1> W2.

  Accordingly, when the door 3 is opened and closed, the bowl-shaped portion 14 does not contact the door 2 as illustrated in FIG. 9 or contacts or rubs against the rotary partition member 8 as in the rotation path D of the bowl-shaped portions 14 and 14a of FIG. Reduce the amount, reduce friction and wear, and suppress the generation of rubbing noise when opening and closing.

  In addition, the bowl-shaped portion 14 having the width dimension W2 has a small amount of contact or rubbing when the door is opened and closed. Furthermore, since the amount of deformation is small, it can be suppressed that the sealing effect of the gap between the rotating partition member 8 and the refrigerator main body is lowered due to long-term use.

  That is, by reducing the width W2 of the hook-shaped portion 14, when the hook-shaped portion 14 overlaps the hook-shaped portion 13, the force for pressing the hook-shaped portion 13 is increased. Furthermore, since the bowl-shaped part 14 is the same dimension in the full length of a height direction, local deformation | transformation is suppressed. Therefore, it is possible to suppress a decrease in the sealing effect of the overlapping portion (overlapping portion).

  Next, an embodiment different from FIG. 5 will be described with reference to FIGS. 2 is a door (left), 3 is a door (right), 7 is a refrigerator compartment, 8 is a rotary partition member, 11 and 12 are door packings, 13 and 14 are bowl-shaped parts, 15 is a dew prevention heater, 17 Is a face plate.

  With reference to FIG. 10, the experimental results of how the door packing looks when the left and right door spacing of a recently sold refrigerator is mounted to a minimum dimension that can open and close the door will be described.

  As a result of this experiment, as shown in FIG. 10, the rotating partition member remained in contact with the bent portion of the door packing being bent. If the state shown in FIG. 10 is not noticed and left unattended, the flange 14 of the door packing 12 undergoes permanent thermal deformation due to overheating of the heater of the rotary partition member 8 and the sealing performance is greatly reduced. This will be described in detail below.

  51 is a door on the side having a rotating partition member, and 52 is the other door. 53 and 54 are door packings provided on the door, and 55 and 56 are bowl-shaped portions of the door packings. The flanges 55 and 56 close the gap between the upper and lower ends of the rotary partition member 57 and the main body. Point a, point b, and point c indicate portions that draw the maximum rotation locus when the doors 51 and 52 rotate when opened and closed.

  When the left and right doors are mounted to a minimum dimension that allows the door to be opened and closed, the hooks 55 and 56 contact the points a, b, and c, but the maximum of the doors 51 and 52 The rotation trajectory points a, b, and c are set to a distance dimension that does not interfere (contact) with each other.

  In this refrigerator, when a state where the doors 51 and 52 stop halfway (so-called half-door state) occurs, the bowl-shaped portion 56 is held in the state shown in FIG.

  In this case, a mechanical bending force is applied to the bowl-shaped portion 56, and the heat of the rotating partition member 57 is applied, so that what should originally be a plane is thermally deformed into a bent shape, and the subsequent sealing effect It has been found that there is a risk that it will not be possible to obtain sufficient.

  In this way, when the left and right door spacing of the currently known refrigerator is mounted small enough to the minimum dimension that can open and close the door, the bowl-shaped portion is caused by the heat of the dew prevention heater 58 of the rotating partition member 57. There is a risk of 56 being thermally deformed.

  FIG. 11 is a diagram for explaining the state of the hook-shaped portions 14 and 14a of the door packing when both doors are opened and closed simultaneously, as in FIG. The width dimension W2 of the bowl-shaped part 14 of a present Example draws the locus | trajectory rotated along the straight line A which equally divides the space | interval (L1 dimension shown in FIG. 4) between doors as shown in FIG.

  On the other hand, the hook-shaped portion 13 on the door 2 side and the rotary partition member 8 draw a rotation locus that is closer to the door 3 side than the straight line A.

  In this case, the flange-shaped portion 14 is set to a width dimension W2 that does not bend greatly with respect to the surface plate 17 of the rotating partition member 8 and that can be bent slightly to the extent that the tip portion contacts.

  Of course, even in the case of this width dimension W2, the overlap (overlapping part) dimension in which the flanges 13 and 14 overlap in the surface plate 17 ensures the dimension W3 shown in FIG.

  As means for this purpose, means for increasing the width dimension W1 of the bowl-shaped portion 13 or decreasing the left and right door distance dimension can be considered. In this embodiment, a means for reducing the door interval dimension is taken.

  Next, the bowl-shaped portion 14 having the width dimension W2 will be described with reference to FIGS. 12, 13, and 14. FIG. Reference numeral 12 denotes a door packing, and the width dimension W2 of the door packing 12 is set to be slightly in contact with the rotary partition member 8 in the state shown in FIG.

  The two hook-like parts 13 and 14 are made asymmetric so as to have a relationship of W1> W2. And as for the width dimension W2 of this bowl-shaped part 14, the full length is set to the width dimension shown in FIG.

  That is, the door packing 12 having the hook-shaped portion 14 has the same width dimension in the entire length in the height direction as shown in FIGS. When the door packing 12 having the hook-like portion 14 and the door packing 11 are combined to ensure an overlapping dimension, the results are as shown in FIGS. In the figure, W1 is the width dimension of the bowl-shaped part 13, W2 is the width dimension of the bowl-shaped part 14, and W3 is the overlapping (polymerization) dimension.

  As shown in FIG. 14, in this figure, since the bowl-shaped portion 14 is on the door 3 side from the middle (straight line A) between the door packings 11 and 12, the bowl-shaped portion 13 side is larger than the width dimension of the bowl-shaped portion 14. It is made and overlaps with the bowl-shaped portion 14 so as to secure the overlap allowance W3.

  In addition, the bowl-shaped part 13 is made by extrusion molding with a molding die with a width dimension W1 shown in the drawing over the entire length in the height direction of the refrigerator. This is cut into the shape shown in the figure, leaving the upper and lower ends, and the width of the hook-like portion is set to W4 in portions other than L2. The width dimension of W4 is set to be equal to W2 or smaller than W2.

  As described above, the bowl-shaped part is made W1> W2, and the W2 width dimension is a dimension that can omit the cutting operation. Therefore, the left and right door spacing dimensions are reduced, and the cost can be greatly reduced, and the reliability is further improved. Can be improved.

  Since the above embodiment has the above-described configuration, it has the following effects.

  That is, a box having a plurality of storage chambers, upper and lower hinges fixed to the box, and doors fixed to the front opening of the box in parallel to the left and right by using the upper and lower hinges as a rotation shaft And a door packing attached to the door in order to prevent cold air leakage between the door and the periphery of the box, and attached to the door to close the space between the doors provided in the left and right side. In the refrigerator provided with the rotating partition member and the hook-shaped portion provided in the door packing so as to close the gap between the upper and lower ends of the rotating partition member and the front opening of the box body, the door packing The width dimension of the hook-shaped part of the door packing is asymmetrical, and the width dimension of the hook-shaped part on the side without the rotating partition member is smaller than that on the other side, thereby ensuring the overlap margin of the hook-shaped part of the door packing. The door pad provided on the door without the rotating partition member By reducing the width of the hook-shaped part of the kin compared to the other side, it is possible to improve the deformation of the hook-shaped part when opening and closing the door and to improve the sealing performance when opening and closing the door. The interval between them can be reduced.

  In addition, the upper and lower ends of the door packing of the door to which the rotating partition member is attached are provided with hook-shaped portions having a large width, and the door packing of the other door has a hook-like shape having the same width and the same height. Since both the upper and lower ends of the rotating partition member are made so that the hook-shaped portions of the door packing of both doors overlap, the extruded one can be used as it is. Can be halved.

  Also, when both doors are closed at the same time, the hook-shaped portion of the other door that approaches the rotating partition member provided on one door contacts the rotating partition member over a wide area as in the conventional case, and the sliding portion is closed. Does not move or is suppressed. Therefore, it is possible to prevent damage due to friction and to prevent the hook-shaped portion from being thermally deformed.

  In addition, the rotation trajectory of the bowl-shaped portion having the same width dimension at the entire height is set to a width dimension that does not slide or abut against the other door except for the rotating partition member. When operating both doors from open to closed at the same time, as described above, the bowl-shaped portion having the same height and the same height does not slide or abut against the rotating partition member in a largely bent state. Therefore, when the door is opened and closed, the hook-like portion on the side without the rotating partition member does not touch the other door. This prevents the hook-shaped portion from being damaged by friction and prevents the hook-shaped portion from sliding or coming into contact. Moreover, compared to the conventional case where sliding or abutting is performed in a state where the hook-shaped portions of both doors are largely bent, wear or noise due to sliding does not occur or can be greatly reduced.

  In addition, when both doors are opened and closed at the same time, the hook-shaped part of the same width dimension at the entire height provided on one door has a small width dimension at the part contacting the rotating partition member. As a result, there is no longer any contact in a largely bent state. As a result, when both doors are simultaneously opened from the closed state, it is possible to prevent the hook-shaped portion contacting the rotating partition member from being worn by sliding, or contacting the rotating partition member. Even if the door is in a half-door state where the door is opened for a long time in the state, since it does not contact in the deformed state, it can be prevented from being permanently deformed by heat.
