Description

Cold storage

The present invention relates to a refrigerator having left and right split door panels.

The refrigerator having the left and right split door pieces has a rotary partition body that blocks the gap of the door piece on the free end side of the single side door piece, and serves as a countermeasure against cold air leakage between the right and left door pieces. When the one-side door piece is opened, the partition body is guided by the shutter body turning guide provided in the refrigerator case, and can be stacked while avoiding the rotation locus of the other side door piece. Further, when the one-side door piece is closed, the partition body is guided by the partition body turning guide and rotated in the opposite direction, and is turned to the back side of the other side door piece to block the gap between the two door pieces.

The separator body has a function of preventing heat from leaking from the inside of the reservoir to the outside of the reservoir, and also preventing heat from entering from the heater for preventing condensation or the outside of the reservoir. However, based on the characteristics of the opening and closing of the door piece and the gap between the two door pieces, the width of the spacer body in the width direction must be set to fill the width of the gap between the two pieces, and in the thickness. The size of the direction must be set so as not to reduce the amount of storage of the door pocket portion and not hit the door panel on the other side. Therefore, it is difficult to increase the size of the separator body in the thickness direction. When the dimension of the separator body in the thickness direction is small, a sufficient thickness as the heat insulating wall cannot be obtained, and therefore, the amount of heat intrusion into the reservoir is increased.

In Patent Document 1, a separator body is disclosed, which is made of a metal plate, The metal plate is sandwiched between the resin front plate member and the resin back plate member to form an outer shape, and a space portion is formed inside. The polyurethane resin having high heat insulating properties is filled and foamed in a space portion inside the separator. An injection hole for filling the polyurethane resin or an air discharge hole for exhausting air in the internal space or gas generated during foaming to the outside is formed on the back surface member of the separator. A heater for preventing condensation on the surface of the metal plate is provided on the back side of the metal plate.

Patent Document 1: JP-A-2011-174625 (pages 4 to 5, Fig. 5)

In the separator body of Patent Document 1, it is almost impossible to secure the thickness of the door piece or the above because of the above-described size limitation. Further, in general, the door piece of the refrigerator has a structure in which a polyurethane resin is internally filled. Therefore, even if the polyurethane resin is filled in the inside of the separator body, the heat insulating performance of the separator body is hardly higher than that of the door sheet. Therefore, in a refrigerator having left and right split door panels, it is very important to reduce the gap between the two door pieces in order to reduce the amount of heat intrusion into the interior of the magazine. In order to reduce the gap between the two door pieces, it is necessary to minimize the gap between the turning track of the partition body and the turning track of the other side door piece.

However, a non-uniform temperature distribution occurs in the constituent components of the separator body. For example, in the case of the separator body described in Patent Document 1, the front portion of the front member of the separator body is in contact with the metal plate heated by the heater, so that the temperature thereof Higher. On the other hand, the back surface portion of the back surface member of the separator body is cooled by the cold air in the storage chamber, so that it is low in temperature. Therefore, the front portion of the front member of the separator body is thermally expanded, and the back portion of the back member of the separator body is thermally contracted. The dimensional change caused by thermal expansion or thermal contraction has a large influence on the longitudinal direction of each member. In addition, the separator body front member and the separator body back member must be integrally formed by being in close contact with each other when the polyurethane resin is filled with air to vent the air to the outside. Further, the separator body front member and the separator body back member are integrally joined to each other by the polyurethane resin filled therein. Therefore, when the front portion of the front member of the separator body is thermally expanded, and the back portion of the back surface member of the separator body is thermally contracted, the separator body is bent and deformed into an arch shape, and the central portion of the longitudinal direction of the separator body is bent and deformed. There will be a situation that protrudes to the outside of the library.

When a portion of the spacer body protrudes toward the outside of the library, the trajectory of the slewing body of the spacer body is enlarged, so that the gap between the trajectory of the other side panel becomes smaller. Therefore, in the case where the gap between the two door pieces is designed to be small, the partition body and the other side door piece come into contact when the door piece is opened and closed, which may cause the separator body or the other side door piece to be broken. On the other hand, in the case where the gap between the two door pieces is designed to be large in order to avoid contact between the partition body and the other side door piece, it is difficult to reduce the amount of heat intrusion into the interior.

The present invention has been made to solve the above problems, and an object of the invention is to provide a refrigerator capable of reducing a heat intrusion into a reservoir by preventing a gap between the two door sheets from being reduced by bending deformation of the spacer body. .

A refrigerator according to the present invention includes: a heat insulating box having an opening formed at a front surface; and a pair of left and right split doors that open and close the opening a spacer; the spacer body is rotatably mounted on the inner side of the free end of one of the door pieces by a hinge member to block the gap between the pieces; and prevent condensation of the spacer body a heater; wherein the separator body has: a front side member disposed on the slit side and provided with the heater; and the front side member is slidably fitted in a longitudinal direction, and the front surface The side members together constitute a back side member of the tubular body; and a heat insulating material provided inside the cylindrical body.

According to the present invention, the front side member and the back side member of the separator body are slidably fitted in the longitudinal direction, whereby the front side member and the back side member can be lengthwise in the longitudinal direction. Increase or decrease, absorbed by sliding each other. Therefore, it is possible to prevent the bending deformation of the separator body. Further, by this, the gap between the two door pieces can be designed to be small, and the amount of heat intrusion into the interior of the library can be reduced.

As shown in FIGS. 1 and 2, the refrigerator 1 has a heat insulating box 10 in which an opening is formed in the front surface. The heat insulating box 10 has, for example, an outer wall formed of a thin metal plate, an inner wall formed of, for example, a resin, and a heat insulating material filled in a space between the outer wall and the inner wall. For example, a foamed polyurethane resin or the like is used as the heat insulating material. Inside the heat insulating box 10, an upper refrigerating chamber 20 and a lower freezing chamber 30 are provided as cold storage chambers having different cooling temperatures. In the refrigerating compartment 20 and the freezing compartment 30 They are separated by a partition member (not shown) formed using a heat insulating material.

The left and right split left door pieces 21 and the right door piece 22 that open and close the opening of the refrigerator compartment 20 are provided at the open end of the refrigerator compartment 20. The left door piece 21 is attached to the left end of the opening of the refrigerating compartment 20 by a hinge member so as to be freely rotatable in a horizontal plane, and the right door piece 22 is rotatably mounted in a horizontal plane by a hinge member. The right end of the opening of the chamber 20. The left door piece 21 and the right door piece 22 have, for example, an outer wall formed of a thin metal plate, an inner wall formed of, for example, a resin, and a heat insulating material filled in a space between the outer wall and the inner wall. A gasket is provided on the outer peripheral portion of the inner side of the left door piece 21 and the right door piece 22, and is adsorbed by the magnet to the sheet metal portion provided at the open end of the refrigerating chamber 20 to prevent leakage of cold air from the refrigerating chamber 20.

Similarly, left and right split left door pieces 31 and right door pieces 32 that open and close the opening of the freezing compartment 30 are provided at the open end of the freezing compartment 30. The left door piece 31 is attached to the left end of the opening of the freezing compartment 30 by means of a hinge member so as to be freely rotatable in a horizontal plane, and the right door piece 32 is attached to the freezer by means of a hinge member so as to be freely rotatable in a horizontal plane. The right end of the opening of the chamber 30. The left door piece 31 and the right door piece 32 have, for example, an outer wall formed of a thin metal plate, an inner wall formed of, for example, a resin, and a heat insulating material such as a space urethane resin filled between the outer wall and the inner wall. A gasket is provided on the outer peripheral portion of the inside of the left door piece 31 and the right door piece 32, and is adsorbed by the magnet to the sheet metal portion provided at the open end of the freezing chamber 30 to prevent cold air from leaking from the freezing chamber 30.

The partition body 40 for blocking the gap 24 between the left door piece 21 and the right door piece 22 of the refrigerator compartment 20 is attached by a hinge member (an upper end side hinge member and a lower end side hinge member) (not shown). The left door piece 21 or the right door piece 22 in the refrigerating compartment 20 The inner side of the free end of one of them (in this case, the left door piece 21). The separator body 40 has a shape of a rectangular column in one direction (the vertical direction of the refrigerator 1). The partition body 40 is attached to the left door piece 21 via a hinge member, whereby the rotation axis 40a can be freely rotated in the horizontal plane. On the other hand, a guide portion 23 (not shown in FIG. 2) for guiding the partition body 40 to rotate is provided on the top surface portion of the refrigerating chamber 20.

When the left door piece 21 is closed, the partition body 40 is rotated in a predetermined direction in accordance with the guidance of the guide portion 23, and is turned into the back side of the right door piece 22 to abut against the gasket of the left door piece 21 and the right door piece 22. Thereby, when the left door piece 21 and the right door piece 22 are in the fully closed state, the gap 24 between the left door piece 21 and the right door piece 22 is blocked by the partition body 40. Further, when the left door piece 21 is opened, the partition body 40 is rotated in a direction opposite to the above direction by the guidance of the guide portion 23, and is stacked while avoiding the rotation locus of the right door piece 22. In Fig. 2, the rotation locus of the right door piece 22 is indicated by a single-point lock line A, and the rotation locus of the partition body 40 is indicated by a single-point lock line B.

A partition body having the same configuration as the partition body 40 of the refrigerating chamber 20 is attached to the inside of the free end of one of the left door piece 31 or the right door piece 32 of the freezing compartment 30.

Fig. 3 is a cross-sectional view showing the structure of a separator 40 according to an embodiment of the present invention. The upper side of the third figure shows the outer side (front side, slit 24 side) of the left door piece 21 and the right door piece 22 in the fully closed state. As shown in FIG. 3, the separator body 40 has a sheet metal member 41, a condensation preventing heater 42, a front side member 43, a back side member 44, and a heat insulating material 45.

The sheet metal member 41 is provided on the outer surface of the bulkhead 40 to form a part of the outer design surface. The sheet metal member 41 has an U shape with one side open The cross-sectional shape is a long metal member in one direction. The sheet metal member 41 is attracted to the magnets of the pads provided on the left door piece 21 and the right door piece 22. In other words, each of the spacers provided on the left door piece 21 and the right door piece 22 is adsorbed to the open end of the refrigerating chamber 20, and the one side is attracted to the sheet metal member 41 of the spacer body 40. Thereby, it is possible to prevent cold air from leaking from the inside of the refrigerating compartment 20 to the outside.

The condensation preventing heater 42 is disposed inside the bank of the sheet metal member 41, for example, on the surface inside the bank of the sheet metal member 41. The condensation preventing heater 42 can heat the sheet metal member 41 to prevent the separator 40 (the surface of the sheet metal member 41) from being condensed. It is possible to use not only the electric heater for converting the electric power into a hot electric heater, but also a condenser for the refrigerating cycle provided in the refrigerator 1 or a refrigerant pipe between the compressor and the condenser as the anti-condensation heater 42.

The front side member 43 has a substantially H-shaped cross-sectional shape having concave portions on both sides, and is a resin member having a long length in one direction. A sheet metal member 41 and a condensation preventing heater 42 are provided in the concave portion on the outer side of the reservoir of the front side member 43. The front side member 43 is fitted with the sheet metal member 41 and the recessed portion to hold the sheet metal member 41 and the condensation preventing heater 42. The front side member 43 and the sheet metal member 41 are slidably fitted in the longitudinal direction. The concave portion inside the reservoir of the front side member 43 and the back side member 44 together constitute a cylindrical body. The front side member 43 is located outside the magazine of the cylindrical body when the left door piece 21 and the right door piece 22 are in a closed state. Further, the front side member 43 and the sheet metal member 41 together constitute an outer peripheral shape of the outer side of the reservoir body 40.

The back side member 44 has a U-shaped cross-sectional shape in which one side is open, and is a resin material having a long length in one direction. The back side member 44 is in the longitudinal direction with respect to the concave portion on the inner side of the front side member 43 (the vertical direction of the refrigerator 1) The housing is slidably slidably formed together with the front side member 43 to form a cylindrical body. In this example, the contact area of the back side member 44 and the front side member 43 is to be made as small as possible. The back side member 44 is located inside the magazine of the cylindrical body when the left door piece 21 and the right door piece 22 are in a closed state. The back side member 44 constitutes an outer peripheral shape of the inside of the reservoir of the separator 40.

The heat insulating material 45 is provided inside the cylindrical body composed of the front side member 43 and the back side member 44. In this example, the heat insulating material 45 is placed in the back side member 44 at the time of assembling the separator body 40. The heat insulating material 45 has a function of preventing heat generated by the condensation preventing heater 42 or heat outside the reservoir from entering the inside of the storage. For example, foamed styrene can be used as the heat insulating material 45.

The fitting of the front side member 43 and the back side member 44 may be a claw fitting. 4 to 6 are views showing an example of a configuration in which the front side member 43 and the back side member 44 are fitted to each other in the spacer body 40 according to the embodiment of the present invention. Fig. 4 is a side view showing a schematic configuration of a side surface of one of the separator bodies 40. Fig. 5 is a cross-sectional view taken along line C-C of Fig. 4, and Fig. 6 is a cross-sectional view taken along line D-D of Fig. 4. As shown in the fourth to sixth embodiments, a plurality of claw portions 46 (for example, a plurality of degrees in the entire longitudinal direction) are partially provided on one side surface of the front side member 43 in the longitudinal direction. The claw portion 46 is formed to protrude downward from the lower end surface 83 of the front side member 43. The groove portion 47 that is fitted (engaged) with the claw portion 46 on one side surface of the back side member 44 is provided to extend in the longitudinal direction. The claw portion 46 and the groove portion 47 are free to slide each other in the longitudinal direction. In the portion where the claw portion 46 is not formed in the longitudinal direction, the contact area of the front side member 43 and the back side member 44 is relatively small, or the front side member 43 and the back side member 44 are not in contact at all. In this example, the lower end surface 83 of the front side member 43 and the upper end surface 84 of the back side member 44 are located substantially in the same plane.

A claw portion and a groove portion are also formed on the other side surface of the front side member 43 and the back side member 44. The other claw portion on the side surface may be provided at a position symmetrical with the claw portion 46 on one side surface, or the claw portion 46 on one side surface and the claw portion on the other side surface may be alternately arranged in the longitudinal direction.

In the present example, the groove portion 47 continuously extends in the entire longitudinal direction of the back side member 44, but the groove portion 47 may be intermittently formed in a portion corresponding to the claw portion 46. In this example, the claw portion 46 is formed on the side of the front side member 43 and the groove portion 47 is formed on the side of the back side member 44. However, the claw portion may be formed on the side of the back side member 44, and the front side member may be formed. The 43 side forms a groove.

In the configuration of the present example, since the front side member 43 and the back side member 44 can be joined by the partial fitting of the claw portion 46 and the groove portion 47, the front side member 43 and the back side member 44 can be formed. The contact area is relatively small. Thereby, the heat transfer area between the front side member 43 and the back side member 44 can be reduced, and therefore, the front side member 43 and the back side member 44 can be thermally insulated from each other. Further, by reducing the contact area, the front side member 43 and the back side member 44 are easily slid freely in the longitudinal direction.

In addition, the spacer body 40 of the present example includes a resin body made of one or both of the front side member 43 and the back side member 44, and the upper end portion of the spacer body 40 is made of resin. The upper end side member; the upper end side hinge member held by the upper end member; and the small end portions of one or both of the front side member 43 and the back side member 44 are fitted to form the lower end of the spacer body 40. a resin-made lower end side member; and a lower end side hinge member held by the lower end side member.

When the refrigerator 1 is operated, the refrigerator compartment 20 is cooled to prevent condensation The heater 42 is heated. As a result, the back side member 44 is cooled by the cold air in the refrigerating chamber 20 and is thermally contracted. On the other hand, the front side member 43 is heated by the heater 42 for preventing condensation and thermally expanded. Both the front side member 43 and the back side member 44 have a lateral dimension (width) larger than a longitudinal dimension (thickness) in FIG. Therefore, the ratio of the entire cooled or heated surface of each member is large. As a result, since the temperature gradient in the longitudinal direction is small in FIG. 3, the front side member 43 and the back side member 44 can suppress the bending deformation caused by the temperature gradient in the plane shown in FIG.

In the longitudinal direction (the depth direction in FIG. 3), the length of the back side member 44 is reduced by heat shrinkage, and the length of the front side member 43 is increased due to thermal expansion. However, in the present embodiment, since the front side member 43 and the back side member 44 are fitted so as to be slidable in the longitudinal direction, the front side member 43 and the back side member 44 are in the longitudinal direction. The increase or decrease of the length is absorbed by the sliding of the front side member 43 and the back side member 44. Therefore, according to the present embodiment, it is possible to prevent bending deformation of the entire separator body 40. Further, by this, the gap 24 between the left door piece 21 and the right door piece 22 can be designed to be small, and the amount of heat intrusion into the refrigerator compartment 20 can be reduced. Further, it is possible to prevent the separator body 40 or the right door panel 22 from being damaged due to the contact between the partition body 40 and the right door panel 22, and it is possible to achieve long-term use of the refrigerator 1.

Embodiment 2

Next, a second embodiment of the present invention will be described. Fig. 7 is an exploded perspective view showing the configuration of the separator body 140 of the present embodiment. It is to be noted that the components having the same functions and functions as those of the separator body 40 of the first embodiment are denoted by the same reference numerals and the description thereof will not be repeated.

As shown in Fig. 7, the separator body 140 of the present embodiment, one or both of the front side member 43 and the back side member 44 (in this example, only the front side member 43) has A part in the longitudinal direction (in this example, a slightly central portion) is divided into two. That is, the front side member 43 is divided into the upper member 43a and the lower member 43b. Each of the upper member 43a and the lower member 43b has joint portions 63a and 63b that can be coupled to each other by fitting or the like.

In the present embodiment, the upper member 43a has a predetermined fitting shape to be fitted to the upper end side hinge member 51, and serves as a hinge member holding portion for holding the upper end side hinge member 51. The lower member 43b has a predetermined fitting shape fitted to the lower end side hinge member 52 as a hinge member holding portion that holds the lower end side hinge member 52. Further, the upper member 43a and the lower member 43b have a predetermined fitting shape to be fitted to the back side member 44. For example, the upper member 43a and the lower member 43b have a shape (a shape in which the upper end and the lower end of the back side member 44 are fitted) at the upper end and the lower end thereof, respectively, at the upper end and the lower end of the back side member 44. Further, the front side member 43 and the back side member 44 composed of the upper member 43a and the lower member 43b are slidably fitted in the longitudinal direction.

The back side member 44 is formed by extrusion molding and has a constant cross-sectional shape in the longitudinal direction. The heat insulating material 45 is surrounded by the back side member 44.

In the present embodiment, since the front side member 43 side has a shape that fits with another member, the shape of the back side member 44 side is less restricted. Therefore, the cross-sectional shape of the back side member 44 can be made constant in the longitudinal direction, and the back side member 44 can be formed by extrusion molding. Thereby, the molding cost of the back side member 44 can be greatly suppressed.

In addition, when the upper member 43a and the lower member 43b have the shape of the upper end and the lower end of the back side member 44, the upper member 43a and the lower member 43b can be covered by the upper member 43a and the lower member 43b. Cut the upper and lower end faces. Therefore, it is possible to realize a separator body 140 which does not allow the user to cut the hand even if the edge treatment of the upper and lower end faces is omitted.

In the present embodiment, the front side member 43 and the back side member 44 are slidably fitted in the longitudinal direction, whereby the same effects as those of the first embodiment described above can be obtained.

In the present embodiment, the front side member 43 (the upper member member 43a and the lower member member 43b) is surrounded by the upper end and the lower end of the back side member 44, and is configured as one side of the front side member 43. The surface side is heated by the heater 42 for preventing condensation, and the other surface side of the front side member 43 is cooled by the cold air in the reservoir. Therefore, in the above-described portion, in the front side member 43, one surface side is thermally expanded, and the other surface side is thermally contracted. However, in the front side member 43, the portion that surrounds the upper end and the lower end of the back side member 44 is a very narrow range of the upper end and the lower end of the spacer body 140, so that the entire bulkhead 140 is bent and deformed. The impact is very slight.

Further, the separator body 140 is a structure having a high aspect ratio in which the dimension in the longitudinal direction is much larger than the dimension in the short-side direction. Therefore, the front side member 43 or the back side member 44 disposed almost across the entire length of the separator body 140 is also a high aspect ratio module. In general, when the assembly is formed by injection molding, it is necessary to select a molding machine based on the dimension in the longitudinal direction. Therefore, in forming a high aspect ratio component, it is necessary to use a large molding machine that molds large components.

In the present embodiment, the front side member 43 is configured to be on the long side. The slightly central portion of the direction is divided into the upper member 43a and the lower member 43b, whereby the aspect ratio of each member (the upper member 43a and the lower member 43b) can be made small. Therefore, a smaller molding machine can be employed to shape the upper member 43a and the lower member 43b. Therefore, the manufacturing cost of the separator body 140 (especially the front side member 43) can be greatly reduced.

In the present embodiment, the front side member 43 is divided into two members (the upper member 43a and the lower member 43b) in the long side, but the front member 43 may be divided. It is more than three members. Further, in the present embodiment, the back side member 44 is not divided. However, the back side member 44 may be divided into two or more members in the long side. When the back side member 44 is divided, the back side member 44 can have a shape to be fitted to another member. Thereby, the cross-sectional shape of the front side member 43 can be made constant in the longitudinal direction, and the front side member 43 can be formed by extrusion molding. Thereby, the molding cost of the front side member 43 can be greatly suppressed.

Further, in the refrigerator 1, when the left door piece 21 is opened and closed, the upper end portion of the partition body 140 is guided by the guide portion 23, whereby the partition body 140 is entirely rotated. Therefore, the separator body 140 must have a predetermined strength in the torsional direction. In general, when the constituent members of the separator body are divided in the longitudinal direction, the strength of the separator body in the torsional direction is lowered. However, in the present embodiment, even if one of the front side member 43 and the back side member 44 is divided, the other member member and the sheet metal member 41 that are not divided can be divided by the reinforcing member. Therefore, it is possible to easily ensure that the bulkhead body 140 as a whole has sufficient strength in the twisting direction.

Further, in the present embodiment, the joint portion of the upper member 43a is Between the joint portion 63b of the 63a and the lower member 43b, a certain length increase and decrease can be absorbed. Therefore, it is possible to prevent the bending deformation of the separator body 140.

Embodiment 3

Next, a third embodiment of the present invention will be described. Fig. 8 is an exploded perspective view showing the structure of the separator body 240 according to the third embodiment of the present invention. It is to be noted that the components having the same functions and functions as those of the separator body 40 of the first embodiment are denoted by the same reference numerals and the description thereof will not be repeated.

As shown in Fig. 8, the separator body 240 of the present embodiment, one of the front side member 43 and the back side member 44 (in this example, the front side member 43) has a portion divided into the following portions. The intermediate member 43e is provided at one end portion (upper end portion) in the longitudinal direction of the intermediate member 43e, and has an upper end member 43c (an example of the end member) which is fitted to the upper end side hinge member 51. And the other end portion (lower end portion) located in the longitudinal direction of the intermediate member 43e, and having a shape lower end member 43d (an example of the end member) fitted to the lower end side hinge member 52. The upper end member 43c has a configuration in which only a portion including a portion (hinge member holding portion) fitted to the upper end side hinge member 51 is separated from the intermediate member 43e. Similarly, the lower end member 43d has a configuration in which only a portion including the portion (hinge member holding portion) fitted to the lower end side hinge member 52 is separated from the intermediate member 43e. The intermediate member 43e is formed by extrusion molding and has a constant cross-sectional shape in the longitudinal direction. Further, the back side member 44 is also formed by extrusion molding, and has a constant cross-sectional shape in the longitudinal direction. The front side member 43 (the upper end member 43c, the lower end member 43d, and the intermediate member 43e) and the back side member 44 are slidably fitted in the longitudinal direction.

In the present embodiment, it can be formed by injection molding. The dimension of the upper end member 43c and the lower end member 43d in the longitudinal direction is minimized, and the aspect ratio can be reduced. Therefore, the mold cost can be reduced to be lower than that of the second embodiment.

Further, in the present embodiment, since the intermediate member 43e and the back side member 44 are formed by extrusion molding, it is necessary to develop the refrigerating in which the lengths of the left door piece 21 and the right door piece 22 in the vertical direction are different. In the case of the library, it is not necessary to re-manufacture the mold for resin molding, and it is also possible to adjust the cut size of the intermediate member 43e and the back side member 44. Therefore, the development cost of the refrigerator having different sizes can be greatly reduced.

Other embodiments

The present invention is not limited to the above-described embodiments, and various modifications can be made.

For example, in the above-described embodiment, the configuration in which both the front side member 43 and the back side member 44 are resin members is exemplified, but one of the front side member 43 and the back side member 44 is used. Or both are metal members.

Further, each of the above embodiments and modifications can be implemented in combination with each other.
