[0106] Refer to FIGS. 20 and 15. The open module 30 of the present invention may achieve miniaturization, particularly, a reduction in thickness in the front-rear direction. By applying the configuration, it is possible to prevent the frost forming, secure stable interlocking between members, and secure a large initial force. To achieve the above-described effects, the present invention has the following operational characteristics. The following description may be identical in the first and second embodiments. Additional explanations will be provided in other cases. 1. The handle 4 may push the link 7 in the pulling direction of the handle 4. The handle 4 may push the link 7 in a forward direction (-Y). The second pressing part 44 may push the third pressing part 72 in a forward direction. Due to the above force action, the thickness of the open module 30 in the front-rear direction (Y) may be reduced. 2. The front surface (-Y surface) of the handle 4 may push the rear surface (+Y surface) of the link 7 in a forward direction (-Y). The front surface of the second pressing part 44 may push the rear surface of the third pressing part 72. Due to the interaction of the above force, the open module 30 may be configured more compactly. 3. Based on the contact portion (C) of the handle 4 and the link 7, the slip length, which is the amount of slip between two members, may be defined. The slip length of the link 7 is smaller than the thickness of the link 7. The thickness of the link 7 may denote the thickness of a cross-section cut normal to the extension direction of the second axis 71. The link 7 has a length, and the direction perpendicular to the length may be defined as a thickness. The thickness of the link 7 may refer to the thickness of the link 7 in the YZ plane in the first embodiment. The YZ plane may refer to the normal plane of the X-axis. The same applies below. The thickness of the link 7 may refer to the thickness of the link 7 in the XY plane in the second embodiment. As the slip length decreases, damage to the member due to friction may be prevented. Reliable operation of the accessed member may be achieved. 4. The contact portion (C) of the handle 4 and the link 7 may pass beyond the second axis 71 when the handle 4 is operated. Before the operation of the handle 4 and the link 7, the contact portion may be placed at the front (+Y) with respect to the second axis 71. After the operation of the handle 4 and the link 7, the contact portion may be placed at the rear (-Y) with respect to the second axis 71. Here, the front and rear may be set as the front (+Y) or rear (-Y) with respect to the XZ plane including the second axis 71. The XZ plane may be the same in the first embodiment and the second embodiment. By changing the position of the contact portion before and after the operation of the handle 4 or before and after the operation of the link 7, the slip length may be provided to be further smaller. Accordingly, damage to the member may be prevented and the operation reliability between the members may be improved. The slip length may occur in both the link 7 and the handle 4. That is, the slip length of the link 7 and the slip length of the handle 4 may occur. In an embodiment, the slip length of the link 7 may be longer than the slip length of the handle 4. This may be because the position of the contact portion of the link 7 passes beyond the second axis 71. 5. The thickness / length (thickness divided by length) of the link 7 may be provided to be greater on the fourth pressing part 73 side than on the third pressing part 72 side. In other words, the aspect ratio of the fourth pressing part 73 may be smaller than the aspect ratio of the third pressing part 72. Here, the thickness and length may be based on a virtual rectangle that accommodates both the third pressing part 72 and the fourth pressing part 73. In the first embodiment, the thickness and length of the link 7 may refer to the thickness and length of the link 7 in the YZ plane. In the second embodiment, the thickness and length of the link 7 may refer to the thickness and length of the link 7 in the XY plane. According to the above configuration, the force amplification due to the lever action may be performed significantly and stably. 6. The thickest part of the handle 4 and the link 7 may be provided on the handle 4. The handle 4 may transmit external force to both the left and right ends. It is preferable that the handle 4 have a thickness sufficient to withstand bending stress. To this end, a plurality of reinforcing ribs may be provided. The reinforcing ribs may make the thickness of the handle 4 in the front-rear direction (Y) greater than that of the link 7. Accordingly, stable operation of the open module 30 can be induced. Accordingly, dimensional errors that may occur during operation can be minimized. 7. A first virtual axis in the front-rear direction (Y) based on the first axis 42 and a second virtual axis in the up / down direction (Z) based on the first axis 42 are provided. In the first embodiment, the second axis 71 may be closer to the second virtual axis than to the first virtual axis. In the second embodiment, the second axis 71 may pass through the second virtual axis. In the second embodiment, the second axis 71 may be parallel to the first virtual axis. When the first axis 42 and the second axis 71 have a certain range, the second axis 71 may overlap with the first virtual axis in the second embodiment. By the above configuration, the open module 30 may be configured compactly 8. The handle 4 may rotate in a first direction around the first axis 42. The link 7 may rotate in a second direction around the second axis 71. In the first embodiment, the handle 4 and the link 7 may rotate in an opposite direction. The handle 4 may rotate clockwise (+X) with respect to the left-right direction (X), and the link 7 may rotate clockwise (+X) with respect to the left-right direction (X). In the second embodiment, the handle 4 and the link 7 may rotate in different directions. In the second embodiment, the handle 4 and the link 7 may rotate in intersecting directions. In the second embodiment, the handle 4 may rotate clockwise (+X) with respect to the left-right direction (X), and the link 7 may rotate clockwise (+Z) with respect to the up-down direction (Z). The open module 30 may be provided in a narrow space by the rotational direction of the handle 4 and link 7 described above. 9. A first virtual axis in the front-rear direction (Y) based on the first axis 42 and a second virtual axis in the up-down direction (Z) based on the first axis 42 are provided. The first virtual axis as X-axis and the second virtual axis as Y-axis may provide a quadrant. For example, a YZ plane may be provided based on the first axis 42 and a quadrant may be provided. At this time, the contact portion (C) of the handle 4 and the link 7 may be placed in at least one of a first quadrant and / or a second quadrant. In the first embodiment, the contact portion may be placed in the second quadrant. In the second embodiment, the contact portion may move the first quadrant and the second quadrant. By the above configuration, a narrow open module 30 in the front-rear direction (Y) may be provided. The open module 30 of the embodiment may be narrow in a width in the front-rear direction (Y), and long in the up-down direction (Z). The open module 30 of the embodiment may have a length in the up-down direction (Z) greater than a thickness in the front-rear direction (Y). 10. A contact portion (C) between the handle 4 and the link 7 is provided. At this time, the distance between the contact portion and the first axis 42 may be greater than the distance between the contact portion and the second axis 71. Here, the distance may be measured based on the YZ plane. In this manner, force amplification by the handle 4 may be induced. Accordingly, an open module 30, which is greater in an up-down direction than in an up-down direction, may be provided. Consequently, a compact open module 30 may be provided. 11. A contact portion (C) between the handle 4 and the link 7 is provided. At this time, the contact portion may move forward (-Y) during operation of the open module 30. By moving the contact portion, the open module 30 may be provided in a narrow space. 12. The link 7 may have a first area close to the second axis 71 and a second area farther from the second axis 71. The first area may be thicker than the second area. This configuration prevents deformation of the member when an external force is applied. Accordingly, force transmission of precise distance and direction may be achieved. 13. The total length of the handle 4 may be longer than the total length of the link 7. Here, the length may be based on the YZ plane. By providing the handle 4 long, the amplification of force by the handle 4 may be significantly induced. By ensuring that the handle 4 is sufficiently elongated in one direction, the open module 30 may be provided in a compact size. 14. The point (see A of FIG. 13) where an external force is applied to the first pressing part 43 is referred to as a point of action. This is referred to as the contact portion (C) between the handle 4 and the link 7. The distance between the point of action (A) and the contact portion (C) may be shorter than the distance between the point of action and the first axis 42. Here, the length may be based on the YZ plane. According to this configuration, the external force applied to the point of action may be amplified and applied to the link 7. Accordingly, the initial opening may be achieved even with a smaller force. 15. A virtual line connecting the first axis 42 and the second axis 71 is provided. The first virtual line may represent the shortest distance between the two shafts. For example, in the second embodiment, the virtual line may be included in the YZ plane. The angle formed by the virtual line with respect to the front-rear direction (Y) may be greater than the angle formed by the virtual line with respect to the up / down direction (Z). The virtual line may be close to a standing position. Here, the standing position may be based on the YZ plane. As described above, the center of motion of the handle 4 and the link 7 may be arranged in the up / down direction Z. In this case, the open module 30 may be configured to be narrow in the front-rear direction. It should be noted that the front-rear direction refers to the thickness direction of the door. Accordingly, a thinner door may be provided. 16. A first virtual line connecting the first axis 42 and the second axis 71 is provided. The first virtual line may represent the shortest distance between the two shafts. For example, in the second embodiment, the virtual line may be included in the YZ plane. The point where an external force is applied to the first pressing part 43 is referred to as a point of action (A). A contact portion (C) between the handle 4 and the link 7 is provided. A second virtual line connecting the point of action and the contact portion is provided. All of the virtual lines may be based on the YZ plane. The length of the first virtual line may be longer than the length of the second virtual line. According to this configuration, each contact portion may be arranged in one direction. Accordingly, an open module 30 that is long in the up-down direction may be provided. 17. The elastic member may come into contact with one surface of the pusher 6 and one surface of the support plate. In the first embodiment, the elastic member may push the pusher 6 in a forward direction (-Y). Accordingly, the accurate operation of the pusher 6 may be guided. The elastic member 64 is provided horizontally, thereby accurately guiding the operation of the pusher 6. 18. The centerline of the elastic member 64 may be above the centerline of the gasket 111. The center of gravity of the elastic member 64 may be placed upward (+Z) than the center of gravity of the gasket. According to this configuration, the pusher 6 and the gasket may operate without interference. By this configuration, a compact open module 30 may be configured.

[0107] FIG. 21 illustrates another embodiment combining the first and second embodiments.

[0108] Refer to FIG. 21A. The handle 4, first axis 42, second axis 71, link 7, and pusher 6 shown in the first embodiment are proposed. It may have a narrow width w1 and a high height H1.

[0109] Refer to FIG. 21B. The present embodiment suggests the handle 4, the first axis 42, the second axis 71, the link 7, and the pusher 6. The second axis 71 may extend in the up-down direction (Z), as in the second embodiment. The open module 30 of the present embodiment may have a narrow width w1 and a high height H1. The open module 30 of the present embodiment may suggest an embodiment in which the position of the pusher 6 is shifted outwards.

[0110] Refer to FIG. 21c. This embodiment suggests the handle 4, the first axis 42, the second axis 71, the link 7, and the pusher 6. The handle 4 is similar to the handle 4 of the first embodiment, but may be provided longer in the left-right direction. The handle 4 is similar to the handle 4 of the first embodiment, but may be provided shorter in the up-down direction. The width and height of the handle 4 may be similar to those of the second embodiment and the handle 4. The open module 30 of this embodiment may have a wide width w2 and a low height H2.

[0111] Referring to FIG. 21D. This embodiment suggests the handle 4, the first axis 42, the second axis 71, the link 7, and the pusher 6. The handle 4 is similar to the handle 4 of the first embodiment, but may be provided longer in the left-right direction. The handle 4 is similar to the handle 4 of the first embodiment, but may be provided shorter in the up-down direction. The width and height of the handle 4 may be similar to those of the handle 4 of the second embodiment. The second axis 71 may extend in the up-down direction (Z) as in the second embodiment. The open module 30 of this embodiment may have a wide width w2 and a low height H2. The open module 30 of this embodiment may have an embodiment in which the pusher 6 is shifted to the outermost position.

[0112] Like the other embodiment, the handle 4 of the second embodiment may be provided in various shapes, similar to the handle 4 of the first embodiment.<Third Embodiment>

[0113] A refrigerator according to a third embodiment will be described below. The refrigerator according to the third embodiment may differ from the other embodiments in the relationship between the cap 8, the handle 4, the case 2, and the front panel 31.

[0114] FIG. 22 is a cross-sectional view showing a cap recess according to the third embodiment. This drawing is a cross-sectional view of the handle of the refrigerator according to the third embodiment, viewed from the YZ plane. The virtual line of the handle in FIG. 22 shows the handle before it rotates.

[0115] Refer to FIG. 22. The cap recess 34 may include an opening through which the grip 5 is inserted. The opening may be provided in the entire area of the cap recess. The cap recess 34 may include both side walls defining both ends of the recess in the left-right direction (X). The cap recess may include a connecting portion connecting the both side walls. The connecting portion may have a lower wall 81 defining a lower portion of the recess. The lower wall may extend in the front-rear direction (Y). A rear wall 82 may be provided at the rear portion of the lower wall. The rear wall may extend in a rearward direction (+Y). The rear wall may extend upward (+Z). A gap for inserting a user's finger may be secured by the rear wall. Even if the width of the door in the front-rear direction (Y) is narrow, a gap for inserting a user's finger may be secured. The rear wall 82 may have at least one round shape. The rear wall may move more in a rearward direction (+Y) as it goes upward (+Z). Accordingly, the width of the cap recess for inserting a user's finger may be secured. For example, the width of the cap recess 34 may be secured to be 12 millimeters. The round shape of the rear wall may have at least two curvature radii. The curvature radius of a curvature radius portion c1 of the lower portion of the rear wall may be larger than the curvature radius of a curvature radius portion c2 of the upper portion of the rear wall. Through this, the insulation effect may be maximized. Through this, the insertion gap of the finger may be secured. The inner support plate 22 may be fastened to at least one of the rear wall and / or the lower wall of the cap recess. By placing the inner support plate on the rear wall and the lower wall of the cap recess, the exact positioning of the open module 30 and the gap may be accurately achieved.

[0116] The cap 8 may be fastened to the outer panel 31. The cap may cover the outer panel. The front upper end of the cap may cover the upper end of the outer panel. The front lower end of the cap may be in contact with the inner surface of the outer panel. The cap may be fastened to the case 2. The front lower end of the cap may be fastened to the outer support plate 21. The upper end of the outer support plate may be in contact with the inner surface of the outer panel. A foam member may be flowed into the upper end of the outer support plate up to the inner surface and the contact portion of the outer panel.

[0117] The outer surface of the case may be bent in response to the operation and shape of the handle 4 and the link 7. By the bending, the case may have a recess extending in the left-right direction (X). The recess may extend in a straight line. The outer support plate 21 may be provided to be curved by the recess. At least two recesses may be provided. The recess may be spaced apart from each other in the up-down direction. The outer support plate may be provided to be curved in the up-down direction. The outer support plate may be inclined rearward (+Y) as it goes downward. The gap between the outer panel 31 and the outer support plate 21 may be larger at the lower side than at the upper side. A foam member may be flowed in from the lower side upward through the gap between the outer panel 31 and the outer support plate 21. The foam member may be flowed in from the lower side of the open module 30. Since the gap between the outer panel 31 and the outer support plate 21 is wider at the lower side, the foam member may be flowed in more smoothly. This is because a foam member with a high pressure may be flowed in through the wider gap at the lower side.

[0118] A foam member may be flowed into the recess. The case may be firmly positioned by the foam member. The foam member may be hardened into a curved shape by the recess. Accordingly, the bonding strength between the foam member and the case may be enhanced. The gap between the outer support plate 21 and the inner support plate 22 may increase as it progresses upward. This facilitates the inflow of the foam member. Accordingly, it may be firmly positioned with respect to the open module 30 and the door. Accordingly, the handle 4 may rotate smoothly around the first axis 42. Accordingly, the link 7 may rotate smoothly around the second axis 71.

[0119] The foam member may be unevenly flowed into the gap between the outer panel 31 and the outer support plate 21. If the gap between the outer panel 31 and the outer support plate 21 is narrow, if the gap between the outer panel 31 and the outer support plate 21 is not wide at the lower side, or if the bonding between the outer panel 31 and the outer support plate 21 is poor, the foam member may be unevenly flowed in. In this case, an unfilled space, in which the foam member is not filled, may occur in the gap between the outer panel 31 and the outer support plate 21. This unfilled space may provide unevenness on the surface of the outer panel. This unevenness may cause long-term defects and deterioration in aesthetic appeal. FIG. 23 is a surface view of the outer panel including the unevenness. The unevenness may be removed by the open module 30 of the present embodiment.<Fourth Embodiment>

[0120] A refrigerator according to a fourth embodiment will be described below. The refrigerator according to the fourth embodiment may differ characteristically from other embodiments in its configuration for enhancing the insulation effect and preventing frost formation.

[0121] FIG. 24 is a drawing showing the insulation effect around the open module in the refrigerator according to the fourth embodiment. The lines in FIG. 24 represent isotherms. When the isotherms become denser, it may denote that the temperature change is severe. When the temperature change is severe, it may denote that heat leakage is severe. Severe heat leakage may degrade insulation performance. Heat may move in the normal direction of the isotherm. FIG. 24 shows the results of a simulation performed using modeling.

[0122] FIG. 24 illustrates the case 2 to which the handle 4 is inserted, the outer panel 31, the inner panel 32, the cap 8, and the dike 35. An insulation gap 38 may be provided inside the door. The insulation gap may accommodate at least a portion of the open module 30. The insulation gap 38 may be filled with a foam member, for example, a polyurethane foam member, to enhance the insulation effect. In addition to the foam member, the insulation gap may also provide insulating members such as vacuum member and porous member. At least two of the above-mentioned insulating members may be provided together.

[0123] The internal area is not provided with an insulating member. The internal area may be considered an insulation-vulnerable area with weak insulation performance. This insulation-vulnerable area narrows the insulation gap 38 of the door, which may lead to a decrease in the door's insulation performance. The insulation performance of the internal area needs to be improved. This may secure the refrigerator's insulation performance. The pressing part may be provided in the same temperature range. The second, third, and fourth pressing parts may be provided in the same temperature range. All pressing parts may be provided in the same temperature range. Accordingly, the pressing part may not be affected by cold air. Accordingly, the temperature difference perceived by a user may be reduced. The isotherm of the internal area may be provided to be wider than the insulation gap. According to this configuration, the internal area's own heat transfer can be reduced.

[0124] The energy nose 39 may block internal airflow to enhance the insulation effect. It may be seen that the isotherm does not pass through the energy nose. The upper end of the dike 35 may create an energy nose. The dike may control the pattern of the isotherm. By controlling the shape of the isotherm, the insulation effect may be enhanced. The dike may have an upper surface that provides the energy nose 39. The dike may have an inner surface extending downward from the upper surface. The dike may have a lower surface that slopes forward from the lower end of the inner surface. The upper surface and the lower surface may have different inclination angles. The inclination angle of the lower surface may be greater than that of the upper surface. Here, the inclination angle may refer to the angle of inclination with respect to the front-rear direction (Y). The inner surface of the dike may have a certain length h1 in the up-down direction (Z). The dike may have a certain length in the front-rear direction (X) to provide an energy nose. The dike may have a length d2 in an up-down direction longer than the length d2 in a front-rear direction. The lower end of the inner surface of the dike may further extend downward from the lower end of the case 2. The dike may be provided in a trapezoidal shape.

[0125] The isotherm of the insulation gap may have a portion extending in a right-downward direction. Here, the right-downward direction may refer to a rearward direction (+Y) and a downward direction (-Z). A sufficient gap between isotherms may be maintained by the right-downward isotherm. By increasing the gap between isotherms, the insulation effect may be enhanced. Despite the thinness of the door, sufficient insulation performance may be achieved. The heat transfer may occur in a left-downward direction due to the isotherm. The dike may be provided at the upper end of the inner panel 32. Here, the left-downward direction may refer to a forward direction (-Y) and a downward direction (-Z). This heat transfer pattern may enhance insulation performance by increasing the heat transfer length.

[0126] The vertical plane (XZ plane) in the front-rear direction (Y) may be the actual extension direction of the wall along which the door provides insulation. The thickness of the door in the length of the front-rear direction (Y) may provide insulation. The energy nose 39 may provide insulation. The thickness of the door including the energy nose may be referred to as the main insulation area. The main insulation area may be referred to as an insulation gap. The main insulation area may include an insulation wall area (d1) and an energy nose area (d2). The insulation wall area may reduce heat conduction. The energy nose area may reduce convection heat through flow. The energy nose area may be equal to the length (d2) of the dike in the front-rear direction. The pusher 6 may be placed in the main insulation area. At least a portion of the pusher 6 may be placed in the energy nose area. At least a portion of the pressing part may be placed in the main insulation area. The entire pressing part may be placed in the main insulation area. This enhances insulation performance. The gasket may be placed in the main insulation area.

[0127] FIG. 25 is a drawing illustrating a configuration for preventing frost formation due to cold air on a refrigerator door according to a fourth embodiment.

[0128] Referring to FIG. 25, the point where frost formation occurs on the door may be a point with the lowest temperature on the outer surface of the door exposed to outside air. The lowest temperature point (C) may be at least one point. The lowest temperature point (C) may be adjacent to a place with which the cap 8 and the inner support plate 22 come into contact. In the open module 30, the lowest temperature point (C) may be a place with which the lower wall 81 and the rear wall 82 come into contact. In the open module 30, the lowest temperature point (C) may be a branching portion (B) where the flow of cold air branches. The branching may mean that the cold air flowing through the inner support plate 22 branches off to the lower wall 81 and the rear wall 82. A heat diffusion member 37 may be installed adjacent to the lowest temperature point (C). The heat diffusion member may be a heat diffusion plate. The heat diffusion plate may promote heat transfer. The heat diffusion member may use a metal plate. The heat diffusion plate may also diffuse cold air. By diffusing the cold air, the lowest temperature point may be prevented from dropping to a frost formation temperature. The heat diffusion plate may be provided on the rear surface of the rear wall 82 adjacent to the lowest temperature point (C). The heat diffusion plate may be provided on the lower surface of the lower wall 81 adjacent to the lowest temperature point (C). The heat diffusion plate may be provided on at least one of the rear surface and / or the front surface of the inner support plate 22 adjacent to the lowest temperature point (C).

[0129] If the door is thin, frost formation at the lowest temperature point may be severe. The heat diffusion plate may prevent frost formation. As an example, the drawing shows that the heat diffusion plate 37 is provided on the outer support plate 21, the lower support plate 23, the inner support plate 22, the rear wall 82, and the upper wall 83.

[0130] A refrigerator according to a fifth embodiment will now be described. The fifth embodiment may differ characteristically from other embodiments in the left-right length of the cap recess and the pusher 6.

[0131] FIG. 26 is a drawing comparing the thicknesses of the door of the fifth embodiment with that of the comparative example. FIG. 26A shows a comparative example in which the cap recess is long horizontally and has a single pusher. FIG. 26B shows a fifth embodiment in which the cap recess is short horizontally and has at least two pushers.

[0132] Refer to FIG. 26. The length b1 of the door end of the fifth embodiment in the front-rear direction (Y) is smaller than the length a1 of the door end of the comparative example in the front-rear direction (Y). Accordingly, the internal volume of the storage space can be increased. The issue of reduced insulation thickness at the door end may be solved by various methods as described. The length b2 of the cap recess of the embodiment in the left-right direction (X) may be larger than the length a2 of the cap recess of the comparative example in the left-right direction (X). Accordingly, the area where the insulation thickness is reduced can be shortened.

[0133] In the comparative example, there is a concern that the initial opening of the door may not be smooth due to a single pusher 6. The concentrated force at one location may not be sufficient for the initial opening of the door. Since the force applied to a single member is large, there is a problem that the size of each member increases. The embodiment may provide at least two pushers 6. The embodiment may provide two pushers 6a, 6b on the left and right sides. The pusher 6 may be provided symmetrically in the left-right direction (X). The pusher 6 may be placed adjacent to dividing points when the door is divided into three parts in the left-right direction (X). The pusher 6 may be placed in the middle area when the door is divided into three parts in the left-right direction (X). The pushers 6 may be placed adjacent to a second dividing point and a fourth dividing point from any one end, when the door is divided into six parts in the left-right direction (X). The drawing shows that it is adjacent to the second dividing point from the left. The pusher 6 may be placed in a third area and a fourth area from any one end when the door is divided into six parts in the left-right direction (X). According to the above configuration, the door may be initially opened with a minimum external force. Accordingly, the force applied to each member may be reduced. Accordingly, each member may be formed thin and long. Accordingly, the open module 30 may be provided in a smaller size.

[0134] The comparative example may be included within the scope of the present invention. The pusher 6 of the comparative example may be provided as a single pusher 6 located in the center of the door in the left-right direction. The single pusher 6 may be implemented by configuring the link 7 as a single unit, changing the position of the axis to the center, changing the position of the handle 4, and changing the vertical position of the pusher 6 to avoid interference.<Sixth Embodiment>

[0135] A refrigerator according to a sixth embodiment will be described below. The sixth embodiment may differ characteristically from other embodiments in the left-right length of the cap recess, the pusher 6, and the handle 4.

[0136] FIG. 27 is a drawing comparing the thicknesses of the door of the sixth embodiment with that of the comparative example. FIG. 27A is a comparative example where a cap recess is shorter in the left-right direction and has two pushers. FIG. 27B is a sixth embodiment where a cap recess is longer in the left-right direction and has at least two pushers. FIG. 27A may be an embodiment of the door suggested in the fifth embodiment. The sixth embodiment may have a cap recess that is shorter in the left-right direction than the comparative example of the fifth embodiment.

[0137] Refer to FIG. 27. The front-rear lengths of the door ends of the comparative example and the sixth embodiment may be the same. The length b2 of the cap recess in the left-right direction (X) of the sixth embodiment is shorter than the length a2 of the door of the comparative example in the front-rear direction (Y). Accordingly, the area where the insulation thickness is narrowed may be shortened. When the cap recess is provided to be longer in the left-right direction, accessibility of user may be improved. User may access not only the center of the door, but also any portion of the cap recess that is wide in one direction.

[0138] In the comparative example, there is a concern that the initial opening of the door may not be smooth even if two pushers 6 are used. This is because the position of the rail to which the door's static friction force is applied and the pusher 6 becomes more distant. In the embodiment, at least two pushers 6 may be provided at positions further outward in the left-right direction. In the embodiment, two pushers 6a, 6b may be provided on both left and right sides. The pushers 6 may be provided symmetrically in the left-right direction (X). The position of the pusher 6 may be positioned as far outward as possible with respect to the left-right direction (X) of the door. Accordingly, the pushers 6 may be adjacent to a pair of rail portions to which the static friction force is applied. The pushers 6 may be positioned outside the cap recess 34. This is because interference may occur when there exists a portion where the pusher 6 and the cap recess are aligned in the front-rear direction (Y). Among a pair of pushers 6, the right pusher 6 may be placed on the right of the cap recess 34. Among the pair of pushers 6, the left pusher 6 may be placed on the left of the cap recess 34. The pusher 6 may interfere with the hinge 14 in the up-down direction (Z). The hinge may rotate the first door 12, 13. The hinge may protrude in the up-down direction from the first door 12, 13. This is because interference may occur when there is a portion where the pusher 6 and the hinge are aligned in the up-down direction (Z). Among the pair of pushers 6, the right pusher 6 may be placed on the left of the hinge 14. Among the pair of pushers 6, the left pusher 6 may be placed on the right of the cap recess 34. In the pusher 6, the length l4 from the center of the door to the pusher 6 in the left-right direction may be longer than the length l3 from the pusher 6 to the distal end of the door in the left-right direction. Accordingly, the position of the pusher 6 can be as close as possible to the rail.

[0139] The handle 4 may be positioned at the center of the cap recess 34. The handle 4 may be provided to be long in the left-right direction (X). As the handle 4 becomes longer, a user may access the handle 4 conveniently. As the cap recess becomes longer, the handle 4 may be provided to be long. The length l1 from the center of the gap recess to the distal end of the handle 4 in the left-right direction may be longer than the length 12 from the distal end of the handle 4 to the distal end of the cap recess in the left-right direction.

[0140] Accordingly, the configuration of the handle 4 may be characteristically provided differently to ensure that the handle 4 and the pusher 6 are adjacent to each other. FIG. 28 is a perspective view of a part related to a handle applicable to the sixth embodiment. The part of FIG. 28 may vary in the parts of the handle 4, the first axis 42, the second axis 71, the link 7, and the pusher 6 of FIG. 21.

[0141] Refer to FIG. 28. The configuration of the handle 4, the first axis 42, the second axis 71, the link 7, and the pusher 6 of the embodiment may be such that, compared to FIG. 21, the distal end of the handle 4 and the pusher 6 may be adjacent. The distal end of the handle 4 of the embodiment may be provided so that the handle 4 is longer in the left-right direction (X) compared to FIG. 21. The distal end of the link 7 of the embodiment may be provided so that the handle 4 is longer in the left-right direction (X) compared to FIG. 21. In the present embodiment, the second area 41 may be reduced in the left-right direction (X). The second area of the present embodiment may have a left-right direction area of the second pressing part 44. The second area may be deleted except for the left-right direction area of the second pressing part 44. According to the present embodiment, the effect of reducing the twisting force of the handle 4 may be obtained.<Seventh Embodiment>
