The engaging part 52 is engaged with the groove part 70 provided in the back surface of the right door 30b, and the gasket 50 is fixed to the right door 30b. When the engaging portion 52 is engaged with the groove portion 70 , the base portion 52 a of the engaging portion 52 closes the opening portion 70 a of the groove portion 70 .

The magnet 54 is accommodated in the magnet accommodating portion 56, and in the closed state of the right door 30b, the magnet 54 is in contact with the peripheral edge portion 15 (the flange portion 36 of the outer case 12a) of the front opening portion 14a. The magnet 54 is formed so that the length in the thickness direction (the vertical direction in the drawing) is longer than the length in the width direction (the left-right direction in the drawing). Moreover, the magnet 54 is provided so that it may be located on the outer peripheral side of the main body rather than the groove part 70 when the main body 12 is viewed from the front. In other words, when the main body 12 is viewed in a front view, the magnet 54 is displaced toward the outer peripheral side of the main body with respect to the groove portion 70 .

The first connecting portion 58 connects the base portion 52 a of the engaging portion 52 of the spacer 50 and the magnet receiving portion 56 . The first connection portion 58 extends from the rear of the surface on the central side of the main body of the magnet housing portion 56 . The first connection portion 58 has a first curved portion 58a that is curved toward the center of the main body. Specifically, the first connecting portion 58 extends from the magnet accommodating portion 56 to the center side of the main body, and after passing over the groove portion 70 , is connected to the base portion 52 a of the engaging portion 52 from the center side of the main body via the first curved portion 58 a that is bent forward. connect. That is, both ends of the first connection portion 58 are connected to the magnet housing portion 56 and the base portion 52a of the engaging portion 52 via the first curved portion 58a.

The second connection portion 60 connects the base portion 52 a of the engaging portion 52 of the spacer 50 and the magnet storage portion 56 . The second connection portion 60 extends from the surface on the center side of the main body of the magnet housing portion 56 and further forward than the first connection portion 58 . The second connection portion 60 has a second curved portion 60a that is curved toward the center side of the main body. Specifically, the second connection portion 60 extends from the magnet accommodating portion 56 to the outer peripheral side of the main body via the second curved portion 60 a that is bent forward in the vicinity of the opening portion 70 a on the outer peripheral side of the main body of the groove portion 70 , and then again toward the center of the main body. The sides are bent and connected to the base portion 52 a of the engaging portion 52 .

The third connecting portion 62 connects between the base portion 52 a of the engaging portion 52 and the first connecting portion 58 . The third connecting portion 62 extends linearly along the thickness direction of the gasket 50 (the vertical direction in the drawing) at the center position in the left-right direction of the engaging portion 52 .

The fourth connecting portion 63 connects between the base portion 52 a of the engaging portion 52 and the first connecting portion 58 at a position closer to the center side of the main body than the third connecting portion 62 . The fourth connection portion 63 has a fourth curved portion 63a that is curved toward the center side of the main body.

The inside of the spacer 50 is divided into a first bag-like portion 90 , a second bag-like portion 90 , a second connecting portion 58 , a second connecting portion 60 , a third connecting portion 62 , and a fourth connecting portion 63 by the base portion 52 a , the magnet housing portion 56 , the first connecting portion 58 , the second connecting portion 60 , the third connecting portion 62 , and the fourth connecting portion 63 . The bag-shaped part 92 and the third bag-shaped part 94 . An air layer is formed in each of the bag-shaped portions 90 , 92 , and 94 , respectively. Specifically, the first pocket portion 90 is a space defined by the magnet housing portion 56 , the first connection portion 58 , the third connection portion 62 , the base portion 52 a , and the second connection portion 60 . The second pocket portion 92 is a space defined by the first connection portion 58 , the fourth connection portion 63 , the base portion 52 a , and the third connection portion 62 . The third pocket portion 94 is a space defined by the first connection portion 58 , the base portion 52 a , and the fourth connection portion 63 .

When the right door 30b is changed from the open state to the closed state, as shown in FIG. 3, an external force is applied to the gasket 50, and the respective pockets 90, 92, 94 are blocked by the peripheral edge 15 of the front surface opening 14a (ie, the outer The flange portion 36 of the case 12a and the flange portion 39 of the inner case 12b are pressed. Thereby, the space between the back surface of the right door 30b and the peripheral edge part 15 of the front surface opening part 14a is sealed. As a result, the interior space S1 of the refrigerator 10 is insulated from the exterior space S2 thereof.

The first protruding portion 64 protrudes toward the center of the main body from the first curved portion 58a. The second protruding portion 66 protrudes toward the center of the main body from a position rearward of the first protruding portion 64 of the first curved portion 58a. The first protruding portion 64 and the second protruding portion 66 extend in a fin shape from the first curved portion 58a toward the center side of the main body. FIG. 5 is an enlarged cross-sectional view around the first protrusion 64 and the second protrusion 66 . As shown in FIG. 5, the thickness of the 1st connection part 58 in the range A1 between the 1st protrusion part 64 and the 2nd protrusion part 66 is thinner than the thickness of the 1st connection part 58 of other parts. In addition, the third protrusion portion 67 protrudes from the front surface of the magnet accommodating portion 56 to the rear surface side of the right door 30b.

As shown in FIG. 6 , in a state in which the spacer 50 has released the external force (ie, the right door 30 b is in an open state), the rear end of the first connection portion 58 is positioned more rearward than the rear surface of the magnet accommodating portion 56 . Location. That is, in each of the pocket parts 90 , 92 , and 94 , the position of the rearmost end is located more rearward than the magnet storage part 56 . Then, when the right door 30b is switched from the open state to the closed state (when switching from the state of FIG. 6 to the state of FIG. 3 ), the gasket 50 (the first connection part 58 ) is pressed by the peripheral edge part 15 as indicated by the arrow Y1 deformation occurs. At this time, as indicated by arrow Y2, the first protrusion 64 moves to the back side of the right door 30b and comes into contact with the back member 48 of the right door 30b on the center side of the main body rather than the groove 70. Moreover, as shown by arrow Y3, the 2nd protrusion part 66 moves to the main body 12 side, and is in contact with the inner case 12b. Moreover, as shown by arrow Y4, the 3rd protrusion part 67 is in contact with the side member 44 of the right door 30b.

(Effect)

In the refrigerator 10 of the present embodiment, the opening 70a of the groove 70 is positioned more rearward (front opening 14a side) than the portion P1 on the body outer peripheral side of the rear surface of the right door 30b. Thereby, since the area|region which the groove part 70 enters into the inner side of the right door 30b is reduced, it is possible to ensure a large interior space of the right door 30b. Therefore, the amount of the heat insulating material to be filled in the inner space of the right door 30b can be increased. In addition, the portion P2 located on the rear surface of the right door 30b at a position closer to the center of the main body than the groove 70 extends in the depth direction of the main body 12 from substantially the same position as the opening 70a of the groove 70 toward the center of the main body. Therefore, the large inner space of the right door 30b on the center side of the main body than the groove portion 70 can be utilized, and the space can be filled with a large amount of heat insulating material. Therefore, in the refrigerator 10 of the present embodiment, the heat flowing into the refrigerator 10 is reduced, and the heat insulation performance of the refrigerator 10 can be improved. In addition, since the portion P2 is usually located closer to the center side of the main body than the center 96 of the pivot shaft of the hinge member 34, the distance between the portion P2 and the peripheral edge portion 15 does not decrease when the right door 30b is opened and closed (see Figure 7). Therefore, even if the part P2 is located at substantially the same position as the opening part 70a of the groove part 70 in the depth direction of the main body 12, the two do not interfere with each other.

In addition, in the depth direction of the main body 12, the position of the side of the opening 70a of the groove portion 70 (the center side of the main body) is substantially the same as the position of the back surface of the right door 30b. Therefore, the refrigerator can be easily manufactured by injection molding. Parts on the back surface of the right door 30b of 10 (the groove part 70, the parts P1, P2, etc.).

Moreover, in the refrigerator 10 of this Example, the 1st connection part 58 and the 2nd connection part 60 each have the 1st bending part 58a and the 2nd bending part 60a which are bent toward the main body center side. Moreover, the 4th connection part 63 also has the 4th curved part 63a curved toward the main body center side similarly. In this way, since each connection part has a part bent toward the center side of the main body, flexibility in the opening and closing direction of the right door 30b can be sufficiently ensured.

In addition, in the spacer 50 of the present embodiment, all the connecting portions 58 , 60 , 62 , and 63 extending from the magnet accommodating portion 56 extend from the surface on the central side of the main body of the magnet accommodating portion 56 . Therefore, the magnet accommodating portion 56 has Most face the outer space S2. Typically, the thermal conductivity of the magnet 54 is higher than that of air. Therefore, the magnet 54 lowers the temperature of the refrigerant on the way from the compressor to the cooler, or absorbs the heat released by the radiator pipe 80 for preventing dew condensation by raising the temperature of the outer surface of the main body 12, thereby promoting Heat is conducted to the inside of the refrigerator 10 . However, in the present embodiment, most of the magnet accommodating portion 56 faces the outer space S2 of the refrigerator 10 , so the heat dissipation toward the outer space S2 side is dominant compared to the inner space S1 side of the refrigerator 10 , and heat can be suppressed. into the refrigerator 10 .

In addition, in the present embodiment, when the main body 12 is viewed from the front, the magnet 54 is positioned closer to the outer peripheral side of the main body than the groove portion 70 . Therefore, compared to the structure in which the groove portion 70 and the magnet 54 overlap when the main body 12 is viewed from the front, the thickness of the entire spacer 50 can be reduced. In addition, in the gasket 50 of the present embodiment, the magnet 54 is offset with respect to the groove portion 70, whereby the thickness of the portion (the pockets 90, 92, 94, etc.) on the center side of the main body than the magnet 54 can be reduced In addition, the thickness of the magnet 54 can be ensured, so that a sufficient magnetic force of the magnet 54 can be ensured. In addition, even when the temperature of the magnet 54 with high thermal conductivity increases, since the magnet 54 is located on the outer peripheral side of the main body, the heat of the magnet 54 hardly flows into the refrigerator 10 . In addition, since the contact area between the entire pockets 90 , 92 , and 94 of the gasket 50 and the magnet accommodating portion 56 is small, it is difficult for heat to be conducted to the inner space S1 side.

In addition, in the closed state of the right door 30b, the first protrusion 64 abuts on the back surface of the right door 30b to form a space S3, the second protrusion 66 abuts against the inner box 12b to form a space S4, and the third protrusion 67 The space S5 is formed in contact with the side member 44 . In this way, in the closed state of the right door 30b, in addition to the respective bag-shaped portions 90, 92, and 94, an air layer shown by the spaces S3 to S5 is formed. Therefore, the thermal conductivity of the entire gasket 50 can be further reduced, and the thermal insulation performance of the refrigerator 10 can be further improved.

In addition, the thickness of the range A1 between the first protruding portion 64 and the second protruding portion 66 of the first connecting portion 58 is thinner than that of the other portions. Therefore, when the right door 30b is closed and each of the pockets 90, 92, and 94 is pressed, the deformation of the gasket 50 in the range A1 is larger than that of the other parts. Therefore, the angles of the first protruding portion 64 and the second protruding portion 66 are easily changed, and the respective protruding portions 64 and 66 can be brought into contact with each surface appropriately.

Moreover, the 1st connection part 58 and the base part 52a of the engaging part 52 are connected by the linear 3rd connection part 62. Therefore, when the right door 30b is opened, the magnet 54 can be efficiently pulled by the third connection portion 62 and separated from the peripheral edge portion 15 .

Moreover, as shown in FIG. 7, the rotation axis center 96 of the hinge member 34 is normally provided in the main body center side rather than the outermost surface of the refrigerator 10. As shown in FIG. Therefore, as shown in FIG. 7 , in the process of opening and closing the door, a timing occurs when the distance between the rear surface of the door and the peripheral edge portion 15 is compared with the distance L between the rear surface of the door and the peripheral edge portion 15 in the closed state. The distance between is closer to the distance L1. In the refrigerator 10 of the present embodiment, the protruding portion 31 provided on the rear surface of the right door 30b has the inclined portion 31a. Therefore, the front end of the protruding portion 31 (the portion closest to the peripheral edge portion 15 in the closed state) is located more than the right door 30b. The outermost side is located closer to the center side of the main body. Therefore, in the process of opening and closing the right door 300b of the refrigerator (refrigerator in which the side surface of the right door 300b is linearly extended rearward) 100 of the comparative example shown in FIG. The distance of the peripheral edge portion 115 is the distance L2, and the distance L1 by which the right door 30b approaches the peripheral edge portion 15 during the opening and closing of the right door 30b is shorter than the distance L2. Compared with the prior art, the front end of the protruding portion 31 and the peripheral edge portion 15 are less likely to interfere, so the distance L can be set shorter. By setting the distance L to be short, it is possible to prevent the user's finger from entering the gap between the right door 30b and the main body 12 .

In addition, by setting the position of the front end of the protruding portion 31 to be closer to the center of the main body than the heat dissipation pipe 80, the path from the heat dissipation pipe 80 to the interior space S1 of the refrigerator 10 is narrowed, so that the heat dissipation pipe 80 can be efficiently moved. The released heat is released toward the outer space S2 side of the refrigerator 10 .

In addition, in the refrigerator 10 of the present embodiment, the distance L between the front end of the protruding portion 31 and the peripheral edge portion 15 is larger than a finger probe (JIS C0922, probe code of 5.6 mm) equivalent to the finger of an infant of about 0 to 3 years old. 19. IEC 61032) narrow. Therefore, it is possible to prevent a child's finger from entering between the right door 30b and the main body 12, thereby improving safety.

In addition, the surface member 40 covering the front surface of the right door 30b and the side member 44 provided on the side surface of the right door 30b are covered with different covering members 42 and 46, respectively. Therefore, compared with the case where the right door 30b is integrally formed, it is easier to manufacture.

Although several embodiments of the present invention have been described, these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the gist of the invention.

In the above-described embodiment, the gasket 50 is attached to the groove portion 70 provided on the back surface of the left and right side doors 30a and 30b of the split type. Install the gasket described in this manual. In addition, the side member 44 of the right door 30b may not have the protruding portion 31 .

These embodiments and modifications thereof are included in the scope and spirit of the invention, and are also included in the inventions described in the claims and their equivalents.
