It is opened and closed by sliding it on.

Further, as shown in FIG. 3, a part of the back surface 2b of the door 2 projects into the storage chamber 10. The protruding portion 2d of the back surface 2b of the door 2 is formed, for example, along the peripheral edge of the back surface 2b of the door 2. The protruding portion 2d does not have to be formed in the door 2.

The refrigerator 100 is not limited to the above configuration, and any or all of the ice making chamber 10b, the switching chamber 10c, and the vegetable compartment 10e may be omitted depending on the form and use of the refrigerator 100, or the refrigerating chamber. One of 10a and the freezer 10d may be omitted. In the present invention, the freezing storage having only the freezing chamber 10d is also included in the refrigerator 100.

Further, the refrigerator 100 may have a plurality of storage chambers 10 for the same purpose depending on the form and use of the refrigerator 100.

Further, in FIG. 1, the opening 1a of the box body 1 is provided in the front direction of the refrigerator 100. For example, as in the refrigerator 100 for business use, the opening 1a of the box body 1 is in the upper surface direction of the refrigerator 100. It may be provided in.

As shown in FIG. 3, the refrigerator 100 is arranged between the box body 1 and the door 2 and includes a gasket 5 that seals the gap 20 between the box body 1 and the door 2. The gasket 5 is arranged along the peripheral edge of the back surface 2b of the door 2 and seals the gap 20 between the box body 1 and the door 2. For example, as shown in FIG. 3, the protruding portion of the back surface 2b of the door 2. It is arranged along the outer peripheral side of the door 2 rather than 2d. Hereinafter, an example of a specific configuration of the gasket 5 will be described with reference to FIG. FIG. 4 is an enlarged view of the gasket 5 of FIG.

The gasket 5 includes a mounting member 51, an accommodating member 53, a magnetic body 53a, a first connecting member 55a, a second connecting member 55b, a third connecting member 55c, an outer packaging member 57a, and a cold air leakage suppressing member 57b. And have.

The mounting member 51 is a member that mounts the gasket 5 on the door 2. The mounting member 51 has a support portion 51a attached to the back surface 2b of the door 2, a body portion 51b connected to the support portion 51a, and a head portion 51c arranged at the tip of the body portion 51b.

As shown in FIG. 3, a groove 2e for engaging the mounting member 51 is provided on the back surface 2b of the door 2. The groove 2e is provided along the peripheral edge of the back surface 2b of the door 2, and is arranged along the outer peripheral side of the protruding portion 2d, for example, as shown in FIG. The cross section of the wall surface 2e1 of the groove 2e on the surface perpendicular to the back surface 2b of the door 2 is formed in a C shape.

The support portion 51a is arranged so as to cover the groove 2e. For example, the support portion 51a is formed as a flat member. Further, the support portion 51a supports the first connecting member 55a, the second connecting member 55b, and the third connecting member 55c on the surface opposite to the surface covering the groove 2e. The body portion 51b is arranged inside the groove 2e and extends from the support portion 51a in the direction of the groove 2e. The head portion 51c is arranged inside the groove 2e, and is engaged with the groove 2e by being locked by a pair of convex portions 2e3 formed on the wall surface 2e1 of the groove 2e. As shown in FIG. 4, the head 51c is, for example, a tapered member, and the width of the head 51c decreases toward the tip of the head 51c. Further, the width of the head 51c in the direction of the convex portions 2e3 is larger than the width between the pair of convex portions 2e3. The shape of the head 51c does not have to be tapered as long as it is locked to the wall surface 2e1 of the groove 2e. Further, the shape of the wall surface 2e1 of the groove 2e does not have to have a C-shaped cross section as long as the head portion 51c can be engaged.

Further, a cavity 51d is provided inside the body portion 51b and the head portion 51c of the mounting member 51. Since the cavity 51d is provided in the body portion 51b and the head portion 51c of the mounting member 51, the elasticity of the body portion 51b and the head portion 51c of the mounting member 51 is increased as compared with the case where the cavity 51d is not provided. growing. Therefore, by providing the cavity 51d in the body portion 51b and the head portion 51c of the mounting member 51, the body portion 51b and the head portion 51c can be easily engaged with the inside of the groove 2e.

Further, in the mounting member 51, the support portion 51a is made of foamed vinyl chloride, and the body portion 51b and the head portion 51c are made of soft vinyl chloride. In the drawings after FIG. 4, each member of the gasket 5 made of foamed vinyl chloride is shown by hatching that rises to the right, and each member of the gasket 5 made of soft vinyl chloride is hatched that rises to the left. It is indicated by.

Here, soft vinyl chloride is a synthetic resin whose softness can be adjusted by adding a plasticizer such as a phthalate ester. Soft vinyl chloride has a higher elasticity than foamed vinyl chloride, but has a characteristic of high thermal conductivity. Further, the foamed vinyl chloride is a synthetic resin formed into a foamed or porous shape by finely dispersing gas in a synthetic resin of vinyl chloride. Foamed vinyl chloride has a lower thermal conductivity than soft vinyl chloride, but has a characteristic of low elasticity.

Since the support portion 51a is arranged in the gap 20 between the box body 1 and the door 2, the support portion 51a is made of foamed vinyl chloride, which is a material having a low thermal conductivity, to form the outside of the storage chamber 10 and the refrigerator 100. It is possible to improve the heat insulation performance between the door and the door. On the other hand, by forming the body portion 51b and the head portion 51c with soft vinyl chloride which is a material having high elasticity, the elastic performance of the body portion 51b and the head portion 51c can be maintained, so that the body portion 51b and the head portion 51c can be formed. The possibility of detachment from the groove 2e can be reduced.

Therefore, according to the mounting member 51 having the above configuration, it is possible to provide the gasket 5 which can secure both the heat insulating performance and the elastic performance and can reduce the possibility that the gasket 5 is detached from the door 2.

The accommodating member 53 is a member accommodating the magnetic body 53a. The magnetic material 53a is formed of, for example, a magnetic material such as ferrite. When the door 2 is closed, the gap 20 between the box body 1 and the door 2 is closed by bringing the accommodating member 53 into close contact with the flange 1b1 of the outer box 1b by magnetic force.

The accommodating member 53 is made of soft vinyl chloride, which is a material having high elasticity. When the door 2 is opened and closed, the accommodating member 53 rubs against the box body 1 to generate a friction noise. When the accommodating member 53 is made of foamed vinyl chloride, which is a material having a low thermal conductivity, the foamed vinyl chloride has a rough surface as compared with the soft vinyl chloride, so that the friction noise becomes louder. Further, the accommodating member 53 is a part of the appearance of the refrigerator 100, and when foamed vinyl chloride is used, it has a rough surface as compared with soft vinyl chloride, so that the design is deteriorated.

On the other hand, if the accommodating member 53 is made of soft vinyl chloride, the frictional noise between the accommodating member 53 and the box 1 can be reduced and the design can be improved as compared with the foamed vinyl chloride. Therefore, by forming the accommodating member 53 with soft vinyl chloride, it is possible to improve the comfort of the user when using the refrigerator 100.

The first connecting member 55a, the second connecting member 55b, and the third connecting member 55c are connected between the mounting member 51 and the accommodating member 53. Further, the first connecting member 55a, the second connecting member 55b, and the third connecting member 55c are arranged at intervals from each other, and are arranged between the first connecting member 55a and the third connecting member 55c, and the second. A space 56 is formed between the connecting member 55b and the third connecting member 55c. By arranging the first connecting member 55a, the second connecting member 55b, and the third connecting member 55c at intervals, heat conduction is blocked by the space 56, so that between the mounting member 51 and the accommodating member 53. Insulation performance can be improved. Further, the first connecting member 55a, the second connecting member 55b, and the third connecting member 55c have a curved shape. Since the first connecting member 55a, the second connecting member 55b, and the third connecting member 55c have a curved shape, when the door 2 is closed, the accommodating member 53 is inserted into the first connecting member 55a, the second connecting member 55b, and the second connecting member 55b. 3 It can be supported by expanding and contracting the connecting member 55c. Further, the second connecting member 55b has a plurality of ribs 57c extending from the second connecting member 55b toward the protruding portion 2d of the back surface 2b of the door 2, and the inflow of cold air in the direction of the mounting member 51. Is suppressed. In the gasket 5, the plurality of ribs 57c and the third connecting member 55c can be omitted.

Further, the second connecting member 55b is arranged on the inner peripheral side of the door. The third connecting member 55c is arranged outside the second connecting member 55b. The first connecting member 55a is arranged outside the second connecting member 55b and the third connecting member 55c. Further, the first connecting member 55a is made of soft vinyl chloride, which is a material having higher elasticity than the second connecting member 55b. Further, the second connecting member 55b is made of foamed vinyl chloride, which is a material having a lower thermal conductivity than the first connecting member 55a.

By forming the second connecting member 55b with foamed vinyl chloride, the heat insulating performance between the storage chamber 10 and the outside of the refrigerator 100 can be improved. Therefore, even if the first connecting member 55a is made of flexible vinyl chloride, it is insulated by the second connecting member 55b and the adjacent connecting members 55 are arranged at intervals, so that the mounting member 51 and the accommodating member are accommodated. The heat insulating performance with 53 can be maintained. Further, even if the accommodating member 53 is made of soft vinyl chloride, if the second connecting member 55b is located closer to the storage chamber 10 than the accommodating member 53 and is arranged so as to cover the storage chamber 10, the box body 1 The heat insulating performance of the gap 20 between the door 2 and the door 2 can be maintained. Therefore, by forming the second connecting member 55b with foamed vinyl chloride, which is a material having a lower thermal conductivity than the first connecting member 55a, the heat insulating performance of the gap 20 between the box body 1 and the door 2 can be maintained.

Further, by forming the second connecting member 55b with foamed vinyl chloride, it is possible to prevent the first connecting member 55a from being cooled by the cold air from the storage chamber 10. Therefore, even when the refrigerator 100 is used under high temperature and high humidity, the occurrence of dew condensation on the first connecting member 55a can be suppressed.

Further, conventionally, in order to suppress the occurrence of dew condensation on the gasket 5, the gasket 5 has been heated by a heating element such as a heater. However, if the second connecting member 55b is made of foamed vinyl chloride, the occurrence of dew condensation on the first connecting member 55a can be suppressed, so that the heater capacity for heating the gasket 5 can be reduced, and the energy of the refrigerator 100 can be reduced. it can.

Further, by forming the first connecting member 55a with soft vinyl chloride, the elastic function between the mounting member 51 and the accommodating member 53 can be improved as compared with the case where the first connecting member 55a is made of foamed vinyl chloride. , Elastic performance can be maintained. Therefore, by forming the first connecting member 55a with soft vinyl chloride and the second connecting member 55b with foamed vinyl chloride, the refrigerator 100 having a gasket 5 capable of ensuring both heat insulating performance and elastic performance is provided. be able to.

Further, if the first connecting member 55a is made of soft vinyl chloride, the sound generated by the expansion and contraction of the first connecting member 55a is reduced as compared with the foamed vinyl chloride, and the design can be improved. Therefore, by forming the first connecting member 55a with soft vinyl chloride, it is possible to improve the comfort of the user when using the refrigerator 100.

Further, when the first connecting member 55a is made of soft vinyl chloride and the second connecting member 55b is made of foamed vinyl chloride, the accommodating member 53 due to the difference in elasticity between the first connecting member 55a and the second connecting member 55b. May stick to the box 1 at an angle. However, if the elasticity of the first connecting member 55a and the second connecting member 55b is adjusted by adjusting the curved shape and length of the first connecting member 55a and the second connecting member 55b, respectively, the accommodating member 53 becomes a box. It is possible to suppress oblique adsorption to the body 1. Therefore, even if the first connecting member 55a is made of soft vinyl chloride and the second connecting member 55b is made of foamed vinyl chloride, the heat insulating performance of the gap 20 between the box body 1 and the door 2 is not impaired.

The outer packaging member 57a is arranged so as to cover the mounting member 51. If the outer packaging member 57a is made of soft vinyl chloride, which is a highly elastic material, the support portion 51a made of foamed vinyl chloride can be made invisible from the outside, so that the design of the gasket 5 is further improved. Further, since the outer packaging member 57a covers the mounting member 51, the air flowing from the outside of the refrigerator 100 to the box body 1 and the mounting member 51 can be shielded.

The cold air leakage suppressing member 57b is connected to the accommodating member 53 and is arranged on the inner peripheral side of the door 2 with respect to the accommodating member 53. The cold air leakage suppressing member 57b has a rib 57b1 extending to a protruding portion 2d of the back surface 2b of the door 2 and a protrusion 57b2 arranged at the tip of the rib 57b1 and having a cavity 57b3 inside. The protrusion 57b2 is arranged between the protruding portion 2d of the back surface 2b of the door 2 and the box body 1, and suppresses the leakage of cold air from the storage chamber 10 when the door 2 is closed. Thereby, the heat insulating performance of the gasket 5 can be improved.

FIG. 5 is a modified example of the gasket 5 of FIG. FIG. 6 is an enlarged view of the gasket 5 of FIG. As shown in FIGS. 5 and 6, the cold air leakage suppressing member 57b shields between the box body 1 and the door 2, and the protrusion 57b2 provides cold air flowing from the storage chamber 10 to the outside when the door 2 is closed. Is blocking. According to this configuration, the heat insulating performance of the gasket 5 can be further improved.

In the gasket 5, the outer packaging member 57a and the cold air leakage suppressing member 57b can be omitted.

Further, the gasket 5 can be integrally molded by simultaneously extruding soft vinyl chloride and foamed vinyl chloride. As a result, the gasket 5 is manufactured in a state where the soft vinyl chloride and the foamed vinyl chloride are adhered to each other, so that the manufacturing man-hours can be reduced.

It should be noted that the physical properties such as elasticity of the soft vinyl chloride used in the gasket 5 do not necessarily have to be the same in each member of the gasket 5. Further, the physical properties such as heat insulating properties of the foamed vinyl chloride used in the gasket 5 do not necessarily have to be the same in each member of the gasket 5.
