Description

Technical Field

[0001] This invention relates to a refrigerator. Background Technology

[0002] A refrigerator has a storage space that can be concealed by a door. Food can be stored at low temperatures in this storage space. The refrigerator utilizes cold air generated through heat exchange with the refrigerant in a circulating cooling cycle. In recent years, with changes in dietary habits and the trend towards more sophisticated products, refrigerators have gradually become larger and more multifunctional. Various refrigerators designed for user convenience and efficient use of internal space have been introduced in recent years.

[0003] The refrigerator's storage space can be opened and closed via a door. Furthermore, refrigerators can be classified into various types based on the layout of the storage space and the structure of the door. For example, refrigerator doors can be opened and closed by rotating or by sliding out / pushing in.

[0004] Users can open and close the door. However, the door can be difficult to operate when it is large and heavy, when there is a large pressure difference between the inside and outside of the refrigerator, and / or when the magnetic force of the door gasket is strong. For example, more force is required to open the door. This can be inconvenient for users. Doors that solve this problem have already been developed. For example, Korean Patent 10-1528729B1. This technology slightly improves user convenience, but other technical problems remain. Summary of the Invention

For example, in the description of this invention, direction can be based on 180 degrees, or on two directions. Towards a certain direction may mean closer to that direction. For example, if towards the right +X, it can be said to be in the range of -90 degrees to +90 degrees, based on the X-axis.

[0068] <First Embodiment>

[0069] Figure 1 This is a perspective view of the refrigerator according to the first embodiment. (Refer to...) Figure 1 The refrigerator 1 may include a cabinet 11 forming a storage space. It may include doors 12, 13, and 20 for opening and closing the storage space. The refrigerator may include a warming cabinet.

[0070] The storage space of the cabinet 11 can be divided by barriers. The storage space can be divided vertically. A refrigerator compartment can be formed in the upper part. A freezer compartment can be formed in the lower part. The door can include first doors 12 and 13 on the left and right sides for opening and closing the refrigerator compartment. The first door can be rotated with a hinge 14 as a support axis. The door can include a second door 20 for opening and closing the freezer compartment. The first door can be mounted to the cabinet 10 using a hinge 13. The first door can open and close the refrigerator compartment by rotating. The second door 20 can be slidably mounted to the cabinet 11. During the sliding action, the cabinet can be pulled out / pulled in. The freezer compartment can be opened and closed by pulling out / pushing in the second door 20. The second door 20 can include a basket on the back of the door. The second door 20 can be referred to as a drawer door 20. The refrigerator of the embodiment can include other types of opening and closing doors. The refrigerator of the embodiment can include combinations of various types of opening and closing doors.

[0071] The first doors 12 and 13 may have contact members. The second door 22 may have contact members. External force may be applied directly to the contact members. External force may be applied indirectly to the contact members. The user can operate the door through the contact members. By operating the contact members, the door can be pulled out from the cabinet. For example, the contact members can overcome at least one of door load, pressure difference between the inside and outside of the refrigerator, and / or magnetic force of the gasket to open the door. At this time, opening the door may refer to initial opening.

[0072] The opening of the door is described below. Door opening can include initial opening and non-initial opening. Initial opening refers to the initial opening of the door as it begins to open. Non-initial opening refers to opening the door after the initial opening has ended. The door load can act as resistance to both initial and non-initial openings. Resistance refers to the force that prevents the door from opening. The pressure difference between the inside and outside of the refrigerator can play a significant role in the initial stage of initial opening. After the initial stage of initial opening, the resistance caused by the pressure difference between the inside and outside of the refrigerator can disappear rapidly. The magnetic force of the gasket can act on the entire structure during initial opening. The magnetic force of the gasket can gradually decrease throughout the entire period of initial opening.

[0073] The contact member can provide a force to overcome the resistance to the initial opening. For example, if the contact member is activated, the door and the enclosure can be initially opened. For example, a user can activate the contact member with their finger to perform the initial opening. Then, the user's arm can move the door. The user can perform operations such as contacting, grasping, pushing, pulling, and / or pressing the contact member. Alternatively, an automatic mechanism can activate the contact member instead of the user. The contact member can be positioned at the corner of the first and second doors. The contact member can be positioned at the upper end of the second door. A guide rail 29 can be provided at the rear of the second door. The guide rail can guide the pulling / pushing of the second door.

[0074] This embodiment uses a bottom-freezing refrigerator with the freezer compartment located at the bottom as an example. This concept can be applied to other types of refrigerators. This concept can also be applied to other types of doors.

[0075] The following embodiment illustrates the use of the contact member in the second door as an example. The door mentioned in the following description is preferably the second door. Of course, the door could also be the first door.

[0076] Figure 2 yes Figure 1 The exploded perspective view of the door is shown in the image. Figure 3 yes Figure 2 Detailed exploded perspective view of the opening module of the first embodiment. (Refer to...) Figure 2 and Figure 3The door may include an outer panel 31 facing the outside of the enclosure and an inner panel 32 facing the inside of the enclosure. The outer panel may be made of metal. The inner panel may be made of resin. The inner panel may be a door liner. The door may include a bottom 311 to protect the lower part. A portion extending from one of the panels may protect the two sides of the door. For example, the two ends of the outer panel may include wings. A cap 8 may be included to protect the top surface of the door. The cap 8 may include a cap recess 34. The cap recess may have a recessed structure for a user's hand to enter. The cap recess may accommodate at least a portion of the contact member. The cap recess 34 may be recessed towards the underside of the cap. The cap recess may include a portion recessed towards the bottom of the door. An opening module 30 may be included that can be linked with the contact member. The opening module 30 may accommodate at least a portion of the contact member.

[0077] Figure 4 This is a diagram showing the opening module and the cap mounted on the outer panel and the inner panel. (Refer to...) Figure 4 The first component can be formed by fastening the opening module 30 and the cap. The second component can be formed by fastening the outer panel, the inner panel, and the bottom. The second component can be fastened to the top surface of the second component, and the above configuration can form a heat-insulating space inside the door.

[0078] Reference Figures 2 to 4 The following description is provided. Foamed components may be filled inside the door. The foamed components may be filled in the internal space defined by the rear of the outer panel, the front of the inner panel, the top of the bottom, the bottom of the cap, and the left and right sides of the wings facing inwards towards the door. The foamed components may also be filled in the external space of the opening module 30. The foamed components may not be filled in the internal space of the opening module 30. Foamed components may be filled between the opening module 30 and the outer panel, between the opening module 30 and the inner panel, between the opening module 30 and the bottom, between the opening module 30 and the cap, and / or between the opening module 30 and the wings. The foamed components may be made of resin, PS (polystyrene), and / or porous materials. Vacuum insulation components may be used in place of or in conjunction with the foamed components.

[0079] The cap 8 can be fastened to at least one of the inner panel and / or the outer panel. The cap can be fastened to at least one of the inner panel and / or the outer panel while the opening module 30 is fastened. The cap can be fastened to the upper end of at least one of the inner panel and / or the outer panel. The cap can be fastened to at least one of the inner panel and / or the outer panel using protrusions and grooves. The inner panel and the outer panel can have the same upper end height. The inner panel and the outer panel can be fastened without recesses and / or protrusions in the front-rear direction Y for fastening the cap. The inner panel and the outer panel can be fastened without recesses and / or protrusions in the vertical direction Z for fastening the cap. At least one of the gap between the cap and the inner panel and / or the gap between the cap and the outer panel can be filled with a foam component. The cap and the opening module 30 can be securely fixed to the door by the foam component.

[0080] The left-right direction of the door can be defined as the X-axis. The inward-outward direction of the door can be defined as the Y-axis. The up-down direction of the door can be defined as the Z-axis. The guide rail 29 can extend along the inner side of the inner panel 32. Prescribed fastening members can fasten the guide rail and the inner panel to each other. Prescribed fastening members can fasten the guide rail mounting base and the guide rail. The guide rail mounting base 321 can be fastened to the inner panel. The guide rail mounting base makes the fastening of the guide rail and the inner panel secure. Due to the guide rail mounting base, even if the door thickness (Y-axis length) is thin, the guide rail can be firmly fixed to the inner panel. The guide rail mounting base 321 can be aligned with the guide rail recess 33.

[0081] The opening module 30 can use the contact member to initially open the door. Figure 5 This is a perspective view illustrating the function of the aforementioned activation module. Figure 5 The diagram shows the state with the cover and housing of the opening module removed.

[0082] Reference Figure 3 and Figure 5 The opening module 30 may include the contact member. The opening module 30 may include a grip 5 for user contact. The contact member may be the grip 5, and the opening module 30 may include a handle 4. The grip may contact the handle 4. The grip may be fastened to the handle 4. If there is no grip, the handle 4 may serve as the contact member. A component that uses external force to activate the opening module 30 may be referred to as a contact member.

[0083] If the grip moves forward (-Y), the handle 4 can rotate. The handle 4 can rotate in a first direction with a first axis 42 as a reference. The handle 4 can rotate the connecting rod 7. The connecting rod 7 can rotate in a second direction with a second axis 71 as a reference. The first direction and the second direction can be opposite directions. The connecting rod 7 can push the pusher 6 backward (+Y). The pusher 6 and the housing can perform action / reaction movements. If the pusher 6 pushes the housing, the door can be initially opened. Here, the housing may include non-moving components that move differently from the door movement.

[0084] The opening module 30 of the first embodiment will be described in detail.

[0085] The opening module 30 may include a handle 4 for external force application. The handle 4 may have a portion extending in the vertical direction Z. The handle 4 may have a first region 40 in its central portion. A grip 5 may be provided in the first region 40. External force may be applied to the first region. The handle 4 may have second regions 41a and 41b on the sides of the first region 40. The lateral length w1 (X-direction length) of the first region may be greater than the lateral length w2 of the second region. By setting the lateral length w1 of the first region to be longer, the torsion of the handle 4 is reduced. The torsion of the handle 4 may occur when the handle 4 is rotated. The torsion of the handle 4 may increase as the grip 5 and the pusher 6 move away in the horizontal direction X. To further reduce the torsion of the handle 4, a plurality of reinforcing ribs 45 may be provided in the handle 4. The reinforcing ribs may be more densely packed in the second region compared to the first region. Thus, the torsion of the handle 4 can be further reduced. The height h1 (Z-direction length) of the first region may be greater than the height h2 of the second region. The height of the first region may be set higher for external force application. The height of the first region can be relatively high to utilize the lever principle to obtain a large force with a small external force. Due to the amplification of the leverage force, the user can operate the handle 4 with a small external force. A first shaft 42 can be provided on the lower side of the handle 4. The first shaft 42 can extend in the left-right direction (X direction). The upper part of the first region can be a first pressure part 43. The upper part of the second region can be a second pressure part 44. If the first pressure part 43 is pushed, the handle 4 can rotate about the first shaft 42. If the handle 4 rotates, the second pressure part 44 can push the connecting rod 7. The cover 3 can support the first shaft 42. The cover can support the handle 4 from the side of the first shaft 42.

[0086] The connecting rods 7a and 7b can be respectively disposed on the left and right sides of the handle 4. The connecting rods 7 can rotate around the second shafts 71a and 71b. The connecting rods 7 may include third pressing portions 72a and 72b disposed on the lower side of the second shaft 71. The connecting rods 7 may include fourth pressing portions 73a and 73b disposed on the upper side of the second shaft 71. The third and fourth pressing portions may have portions extending in the vertical direction Z. The third and fourth pressing portions may have reinforcing ribs. The reinforcing ribs can prevent deformation of the connecting rods 7. The lengths of the third and fourth pressing portions may be different from each other. Lever operation can be performed by adjusting the lengths of the third and fourth pressing portions. For example, the third pressing portion 72 can be shorter than the fourth pressing portion 73. In this case, even if the third pressing portion 72 moves a short distance, the fourth pressing portion 73 can move a longer distance. Thus, the movement distance of the pusher 6 can be ensured. The second pressure part 44 can push the third pressure part 72. If the second pressure part 44 is pushed, the connecting rod 7 can rotate about the second shaft 71. If the connecting rod 7 rotates, the third pressure part and the fourth pressure part can rotate together. The fourth pressure part 73 can push the pushers 6a and 6b. There can be at least one connecting rod 7. There can be two connecting rods 7. The connecting rods 7 can be arranged in pairs on the left and right sides of the handle 4. The connecting rods 7 can use balanced forces to initially open the door. One end of the second shafts 71a and 71b can be supported by the cover 3. The other end of the second shafts 71a and 71b can be supported by the housing.

[0087] The pushers 6a and 6b can be located between the opening module 30 and the housing 11. The pusher 6 can include the action / reaction point of the door and the housing. The pusher 6 can have an outer end 61 extending in the vertical direction Z. The outer end can remain in contact with each other even when the position changes due to the rotation of the fourth pressure part 73. The pusher 6 can have an extension 62 extending in the front-rear direction Y. The extension can increase the working length of the pusher 6. The rear end of the extension can have an inner end 63. The inner end can be connected to the housing 11. If the pusher 6 is pushed backward, the inner end can push the housing. The inner end can be referred to as the push end. The front-rear length of the extension can be longer than the vertical length of the outer end. The height of the inner end can be longer than the height of the extension. The fourth pressure part 73 can push the outer end. If the outer end is pushed, the pusher 6 can move backward as a whole. The covers 3a and 3b can guide the pusher 6. At least one rib may be provided on the cover to guide the movement of the pusher 6. The rib may extend in the front-rear direction Y. Due to the first lever action of the handle 4 and the second lever action of the connecting rod 7, the force applied to the pusher 6 can be amplified. Due to the first lever action of the handle 4 and the second lever action of the connecting rod 7, the movement distance of the pusher 6 can be ensured.

[0088] The first pressing part 43 and the fourth pressing part 73 can be arranged in the upper direction +Z relative to the first rotation axis. The first pressing part 43 and the fourth pressing part 73 can be arranged in the same direction relative to the first rotation axis. The first pressing part 43 and the fourth pressing part 73 can be arranged in the upper direction +Z relative to the second rotation axis. The first pressing part 43 and the fourth pressing part 73 can be arranged in the same direction relative to the second rotation axis. The first pressing part 43 can be a pressing part that initiates the application of external force. The fourth pressing part 73 can be a pressing part that ultimately pushes the pusher 6. The second pressing part 44 and the third pressing part 72 can be arranged in the upper direction +Z relative to the first rotation axis. The second pressing part 44 and the third pressing part 72 can be arranged in the lower direction -Z relative to the second rotation axis. The first rotation axis can be arranged in a lower direction lower than the second rotation axis. According to the above configuration, the width of the opening module 30 in the front-rear direction Z can be narrowed. Therefore, the front wall of the door can be constructed thinner. This extends the front-to-back insulation length of the door, thus improving insulation performance and allowing for a larger internal volume of the refrigerator.

[0089] The grip 5 can be located on at least one of the upper and / or rear parts of the handle 4. The user can easily access the grip. Due to the first and second lever actions, the external force acting on the grip can be amplified. For example, even with a small force applied by the user, the door can be initially opened. Initial opening can be achieved with a small grip of the fingers. During initial opening, only the grip of the hand may be in effect. During initial opening, the force of the arm other than the fingers may be ineffective. Under the first and second lever actions, the ratio of the movement distance of the handle 4 to the movement distance of the pusher 6 can be adjusted. As a result, the external force applied by the user to the handle 4 and the movement distance of the handle 4 can correspond to the force of the pusher 6 pushing the housing and the distance the pusher 6 moves the housing. The rotational action of the handle 4 can be converted into the translational action of the pusher 6 pushing the housing.

[0090] The housing 2 can accommodate at least a portion of the handle 4. The housing can guide the movement of the handle 4. The housing can guide the position of the handle 4. The housing may include an external support plate 21 providing a front-Y wall. The housing may include an internal support plate 22 providing a rear wall. The housing may include a lower support plate 23 providing a lower wall. The lower support plate may connect the lower portions of the internal support plate and the external support plate front to back. The side of the housing may include an opening gap 25. The second region 41 can extend laterally through the opening gap. Above the opening gap 25 may include a shaft support portion 26. The shaft support portion can support the second shaft 71. The shaft support portion may include a cylindrical structure supporting the inner side of the second shaft 71. The upper part of the housing may be open. The handle 4 can be assembled through the upper part of the housing. The upper part of the internal support plate 22 may include fitting portions 24a, 24b extending rearward +Y. The fitting portions can guide the position of the opening module 30 and the cap 8. For example, the opening module 30 and the cap can be assembled through the fitting portions. The mating part 24 can guide the movement of the pusher 6.

[0091] The cover 3 can be disposed on the left or right side of the housing. The cover can shield the internal space of the housing 2 relative to the outside. The cover can block the inflow of the foaming component. The cover can have shaft support portions that support the first shaft and the second shaft. The cover can guide the movement of the pusher 6.

[0092] The second axis 71 can be positioned forward (-Y) than the first axis 42. The second axis 71 can be positioned above the first axis 42 (+Z). The second axis 71 can be closer to the user than the first axis 42. Therefore, the user's grip 5 can be closer to the user. The user can operate the opening module 30 more conveniently. The user can operate the grip with less force.

[0093] Figure 6 This is a diagram illustrating the structure of the pressurizing section. Figure 6 (a) is Figure 1 Three-dimensional view of the cross section of 6a-6a'. Figure 6 (b) is Figure 1 A three-dimensional view of the cross-section of 6b-6b'. Figure 6 (b) is Figure 1 A three-dimensional view of the cross-section of 6b-6b'.

[0094] Reference Figure 6 This describes the operation of the pressure unit. In a static state, at least one of the handle 4 and / or the connecting rod 7 can be in contact with at least one of the inner support plate 22, the outer support plate 21, and / or the cap 8. In a static state, the handle 4 can be in contact with at least one of the cap 8 and / or the inner support plate 22. In a static state, the connecting rod 7 can be in contact with the outer support plate 21. Under the action of an external force, the grip 5 can push the first pressure unit 43. The first pressure unit 43 can rotate. The first pressure unit 43 and the second pressure unit 44 can rotate in the same direction. The second pressure unit 44 can push the third pressure unit 72. The second pressure unit 44 and the third pressure unit 72 can rotate in different directions. The third pressure unit 72 can rotate. The third pressure unit 72 and the fourth pressure unit 73 can rotate in the same direction. As described above, the pressure unit can rotate around a first axis and a second axis. The fourth pressurizing part 73 can push the pushing member 6. The pressing end 63 of the pushing member 6 can push the box body. The pressing end can push the partition wall of the storage compartment. The box body can refer to the outermost panel of the box body. The pressing end can push the outside of the liner 111.

[0095] The thickness w11 of the first region 40 and the thickness w12 of the second region 41 can be the same. The ratio h1 / w11 of the thickness w11 of the first region 40 to its height h1 can be greater than the ratio h2 / w12 of the thickness w12 of the second region 41 to its height h2. This further reduces the torsion in the second region. When the handle 4 is actuated, the second region can generate a greater torque than the first region.

[0096] Figure 7This is a side sectional view comparing the opening module before and after its operation. Figure 7 (a) and Figure 7 (b) can be in a static state. Figure 7 (c) can be an action state. Figure 7 (a) can be with Figure 6 (a) corresponds to. Figure 7 (b) and Figure 7 (c) can be with Figure 6 (b) corresponds to.

[0097] Reference Figure 7 When the opening module 30 is activated, the handle 4 can rotate counterclockwise around the first axis 42. When the opening module 30 is activated, the connecting rod 7 can rotate clockwise around the second axis 71. When the opening module 30 is activated, the pushing member 6 can move forward. An elastic member 64 can be provided to control the movement of the pushing member 6. The elastic member can return the pushing member 6 to a stationary state. The elastic member can be located between the outer end 61 of the pushing member 6 and the cover 3.

[0098] A padding recess 36 can be provided on the lower side of the cap recess 34. The padding 111 can be fixed in the padding recess 36. A spacer 35 can be provided at the rear +Y of the opening module 30. The spacer can increase the heat insulation thickness of the wall where the opening module 30 is located. The spacer can provide an energy nose. The energy nose can improve the heat insulation effect by blocking the airflow in the storage space.

[0099] Figure 8 This is a diagram showing the tightening process of the opening module. Figure 8 The accompanying drawings illustrate the fastening of the various components.

[0100] Reference Figure 8 . Figure 8 (a1) shows the elastic member 64 fastened to the pusher 6. The elastic member can guide the pusher 6 to a rest position. The elastic member can pull or push the pusher 6 forward-Y. Figure 8 (a2) shows the handle 4 being fastened to the housing 2. Figure 8 (b) shows the pusher 6 fastened to the cover 3 and the connecting rod 7 fastened to the cover. The movement of the pusher 6 can be guided by the cover. The elastic member can be disposed between the pusher 6 and the cover. At least a portion of the connecting rod 7 can be disposed in front of the pusher 6. One side of the second shaft 71 of the connecting rod 7 can be supported by the cover. The state in which the various components are fastened to the cover can be referred to as the cover assembly.

[0101] Figure 8 (a2) shows that the left second region 41a of the handle 4 moves deeper to the left through the opening gap 25a of the left-X direction. At this time, the handle 4 can be in a rightward and upward tilted posture. It can be in the state where the handle 4 is tightened to hold the grip. Then, the handle 4 can be aligned horizontally. The handle 4 can be moved to the right. By this action, the left second region 41a of the handle 4 can be moved to the right through the opening gap 25a of the left side. By this action, the right second region 41b of the handle 4 can be moved to the right through the opening gap 25a of the right side +X direction. Through this process, the handle 4 can be aligned in an accurate position within the housing. The component in which the handle 4 is set in the state of the housing is called the handle 4 assembly.

[0102] Figure 8 Figure (c) shows the cover assembly and the handle 4 assembly fastened together. The two assemblies can be fastened by the engagement of protrusions and recesses. The cover can be fastened to both sides of the housing 2. The first shaft 42 can be supported on the cover. The second shaft 71 can be supported on the cover. The first shaft 42 can be supported only on the cover. Each of the second shafts 71 can be supported on both the cover and the housing.

[0103] Figure 8 Figure (d) shows the opening module 30 and the cap fastening. The cap can be fastened to the upper end of the opening module 30. The cap can be fastened to the connecting rod 7. The cap can be fastened to the mating part. The various components can be fastened by the engagement of protrusions and recesses. The cap recess 34 and the grip 5 can be aligned in a precise position. The single unit fastened to the cap and the opening module 30 can be fastened to the panels 31, 32. The single unit can be fixed by the cap 8 fastened to the panels 31, 32. The opening module 30 may not be fixed to the panels. The internal support plate 22 may not be in contact with the panels 31, 32. Then, as... Figure 4 The instructions and instructions state that it can be fastened to door 20.

[0104] The area inside the housing 2 and the cap 8 can be referred to as the internal region. No foaming component may be provided in the internal region. An opening module 30 may be provided in the internal region.

[0105] Figure 9 This is a comparison diagram of the internal regions. The internal regions can be based on their maximum range in the front-back and up-down directions. Figure 9 (a) is a diagram showing the internal region of the comparative example. Figure 9 (b) is a diagram illustrating the internal region of the embodiment. The internal region may be represented by a rectangle. The comparative example and the embodiment may be configurations required to operate doors of the same size and weight.

[0106] Reference Figure 9 In the comparative example, the ratio W1 / H1 of the vertical Z-axis dimension H1 to the horizontal Y-axis dimension W1 in the internal region can be greater than 1. In the embodiment, the ratio W2 / H2 of the vertical Z-axis dimension H2 to the horizontal Y-axis dimension W2 in the internal region can be less than 1. In the embodiment, the ratio W2 / H2 of the vertical Z-axis dimension H2 to the horizontal Y-axis dimension W2 in the internal region can be less than 0.5. Based on these ratios, the horizontal thickness of the internal region can be reduced. Therefore, the door thickness can be reduced. If the door thickness is reduced, a larger storage space can be obtained, enhancing the user's aesthetic experience.

[0107] <Second Embodiment>

[0108] The refrigerator of the second embodiment will now be described. The opening module and related configuration of the refrigerator of the second embodiment may differ from those of other embodiments.

[0109] Figure 10 This is a perspective view of the refrigerator according to the second embodiment.

[0110] Reference Figure 10 The refrigerator 1 may include a cabinet 11 forming a storage space. It may include doors 12, 13, and 20 for opening and closing the storage space. The refrigerator may include a warming compartment. The first door can rotate with a hinge 14 as a support axis. The door may include a second door 20 for opening and closing the storage compartment. The second door 20 may be slidably mounted to the cabinet 11.

[0111] The second door may have a pusher 6. The second door may have at least two pushers 6. Compared to the first embodiment, the position of the pusher 6 can be moved along the left and right ends of the door. The pusher 6 may overlap with at least a portion of the guide rail mounting base 321 in the vertical direction. The pusher 6 and the guide rail mounting base 321 may not overlap in the vertical direction. In this case, compared to the first embodiment, the pusher 6 and the guide rail mounting base 321 may be adjacent to each other. The guide rail mounting base may overlap with the guide rail 29 in the front-back direction. The pushing action of the pusher 6 can be directly applied to the guide rail. Here, "directly applied" may mean that the torque in the left-right direction X is absent or very small. The pushing action of the pusher 6 can be directly applied to the load. Here, the load may refer to the guide rail that supports the door and accommodates objects. Thus, the door 20 can open smoothly. This action may be due to the rotation direction of the second shafts 71a, 71b being parallel to the Z-axis and / or the connecting rods 7a, 7b moving towards the left and right ends of the door. Details of the connecting rod 7 and the second shaft 71 will be explained later.

The first direction can be a rotation direction with the left-right direction X as the central axis. The handle 4 can cause the connecting rod 7 to rotate. The connecting rod 7 can rotate in a second direction with a second axis 71 as a reference. The second axis 71 can extend in the up-down direction Z. The second direction can be a rotation direction with the up-down direction Z as the central axis. The first direction and the second direction can be intersecting each other. The first direction and the second direction can be orthogonal. The connecting rod 7 can push the pusher 6 backward +Y. The pusher 6 and the housing can perform action / reaction movements. If the pusher 6 pushes the housing, the door can be initially opened.

[0118] A first pressure section 43 may be provided at the upper part of the first region. The first pressure section 43 may include a vertically extending section 431. The vertical section 431 may be the part that the user's fingers directly contact. A horizontal section 432 may be provided at approximately the middle or lower part of the vertical section. The height of the vertical section may vary depending on the depth or shape of the cap recess. The horizontal section may extend rearward + Y from the back of the vertical section. The horizontal section may have a predetermined length in the left-right direction. The horizontal section may extend along the top surface of the bottom wall of the cap recess 34. The horizontal section may prevent external substances from flowing into the opening module 30. At least a portion of the horizontal section may be in contact with the wall of the cap recess. The horizontal section may slide along the wall of the cap recess.

[0119] A second pressure part 44 can be provided at the upper part of the second region. If the first pressure part 43 is pushed, the handle 4 can rotate about the first axis 42. The handle 4 can rotate about the first direction as the central axis. The first axis 42 can be fastened to the lower part of the handle 4. The first axis 42 can be fastened to the inner support plate 22 by the first axis 42 mounting base 421. The first axis 42 mounting base and the inner support plate can be fastened to each other by a fastening tool. Here, the fastening tool can be a screw.

The second axis 71 can extend in the vertical direction Z. The second axis 71 can intersect with the first axis 42. The connecting rod 7 can extend in the horizontal direction X. The connecting rods 7a and 7b can include a third pressure part 72 disposed on the inner portion of the connecting rod 7. The connecting rod 7 can include a fourth pressure part 73 disposed on the outer portion of the connecting rod 7. Since the fourth pressure part 73 is disposed on the outer side of the connecting rod 7, the pusher 6 can be located further outward. Here, the inner and outer sides of the connecting rod 7 can be referenced to the center of the opening module 30. Unless the reference for the inner and outer sides is described, the center of the opening module 30 can be used as the reference. The third pressurizing part 72 and the fourth pressurizing part 73 may be adjacent to the extended end of the connecting rod 7. The fourth pressurizing part 73 may push the pushers 6a and 6b.

The first shaft 42 and the second shaft 71 can extend in directions that are orthogonal to each other. Therefore, the push member 6 can be located further outward. Therefore, the push member 6 and the guide rail mounting base can overlap or be adjacent in the vertical direction. Therefore, the front wall of the door can be constructed thinner. Therefore, the insulation length can be increased. Therefore, the insulation effect can be improved. Therefore, the internal volume of the refrigerator can be increased. Therefore, the user can open the door conveniently with less force.

[0123] The housing may have a support plate. The support plate may include an inner support plate 22 and an outer support plate 21. The inner support plate 22 may be provided with a rearwardly recessed +Y-shaped recess 9. The recess 9 may accommodate at least a portion of the handle 4.

[0135] Reference Figure 17 (c) The inner support plate 22 can securely hold the covers 3a and 3b. The first surface of the cover can include a second shaft 71 support portion 26 supporting the lower end of the second shaft 71. Here, the first surface of the cover can be the top surface of the cover. The second surface of the cover can include a first shaft 42 support portion 27 supporting the ends of the second shafts 71 and 42. The second surface can be the side surface of the cover.

(a) is a perspective view of handle 4, (b) is a sectional view of the mounting base of the first axis 42 cut along the YZ plane, and (c) is a perspective view of the bottom surface before the cover is tightened. (Refer to...) Figure 18The first pressing part 43 and the second pressing part 44 of the handle 4 can be bent forward at a predetermined angle (+Y). The bending angle α of the first pressing part 43 is smaller than the bending angle b of the second pressing part 44. According to this configuration, the opening module 30 can be configured within a narrow range in the forward and backward direction (Y).

The inner surface area of ​​the slit can be slightly larger than the cross-section of the outer end. The protective cap 95 can be fixed by fastening it to at least one of the internal support plate, the cover, and / or the cap by fastening rib 951. Alternatively, it can be fastened using a separate fastening member. It can prevent the inflow of external foreign objects through the slit. It can prevent product failure.

[0140] Figure 20 The diagrams illustrate the relationship between the shaft, handle, and connecting rod. (a) is a diagram showing the function of the handle, connecting rod, and pusher in the first embodiment, and (b) is a diagram showing the function of the handle, connecting rod, and pusher in the second embodiment.

[0141] Simultaneously refer to Figure 20 and Figure 15 The opening module 30 of the present invention can be miniaturized, and in particular, the thickness of the opening module 30 in the front-rear direction can be reduced. While applying the above-described configuration, condensation can be prevented, stable inter-component linkage can be ensured, and a large initial force can be generated. To achieve the above effects, the present invention has the following functional features. The following description can be the same in the first and second embodiments. If there are differences, they will be described separately.

[0142] 1. The handle 4 can push the connecting rod 7 in the direction in which the handle 4 is pulled. The handle 4 can push the connecting rod 7 forward -Y. The second pressure part 44 can push the third pressure part 72 forward. Due to the above-mentioned force, the thickness of the opening module 30 in the front-rear direction Y can be reduced.

[0143] 2. The front (-Y side) of the handle 4 can push the back (+Y side) of the connecting rod 7 forward by -Y. The front of the second pressure part 44 can push the back of the third pressure part 72. Due to the aforementioned reverse force, the opening module 30 can be configured more compactly.

[0144] 3. The slip length, representing the amount of sliding between the two components, can be defined based on the contact portion C between the handle 4 and the connecting rod 7. The slip length of the connecting rod 7 is less than the thickness of the connecting rod 7. The thickness of the connecting rod 7 can refer to the thickness of the cross-section cut with the extension direction of the second axis 71 as the normal. The connecting rod 7 has a length, and the orthogonal direction of the length can be defined as the thickness. In the first embodiment, the thickness of the connecting rod 7 can refer to the thickness of the connecting rod 7 in the YZ plane. The YZ plane can refer to the normal plane of the X-axis. The same applies below. In the second embodiment, the thickness of the connecting rod 7 can refer to the thickness of the connecting rod 7 in the XY plane. The smaller the slip length, the better it is possible to prevent damage to the components caused by friction. This ensures reliable operation of the connected components.

[0145] 4. The contact portion C of the handle 4 and the connecting rod 7 can pass over the second axis 71 when the handle 4 is actuated. Before the handle 4 and the connecting rod 7 are actuated, the contact portion can be positioned forward +Y with reference to the second axis 71. After the handle 4 and the connecting rod 7 are actuated, the contact portion can be positioned rearward -Y with reference to the second axis 71. Here, the forward and rearward positions can be set forward +Y or rearward -Y with reference to the XZ plane including the second axis 71. The XZ plane can be the same in the first embodiment and the second embodiment. By changing the position of the contact portion before and after the actuation of the handle 4 or the actuation of the connecting rod 7, the sliding length can be reduced. This can prevent damage to the components and improve the reliability of the operation between the components.

[0146] Both the connecting rod 7 and the handle 4 can exhibit the aforementioned sliding length. That is, both the connecting rod 7 and the handle 4 can exhibit a sliding length. In this embodiment, the sliding length of the connecting rod 7 can be longer than the sliding length of the handle 4. This may be because the position of the contact portion of the connecting rod 7 extends beyond the second axis 71.

[0147] 5. The thickness / length (thickness divided by length) of the connecting rod 7 in the fourth pressure section 73 can be greater than the thickness / length of the connecting rod 7 in the third pressure section 72. In other words, the aspect ratio of the fourth pressure section 73 can be less than that of the third pressure section 72. Here, the thickness and length can be based on a virtual rectangle accommodating the third pressure section 72 and the fourth pressure section 73. The thickness and length of the connecting rod 7 can refer to the thickness and length of the connecting rod 7 on the YZ plane in the first embodiment. The thickness and length of the connecting rod 7 can refer to the thickness and length of the connecting rod 7 on the XY plane in the second embodiment. According to this configuration, the force amplification based on the lever action is large, and it can be executed stably.

[0148] 6. The thickest part of the handle 4 and the connecting rod 7 can be located in the handle 4. The handle 4 can transmit external force to the left and right ends. Preferably, the handle 4 has a thickness that can correspond to the degree of bending stress. For this purpose, a plurality of reinforcing ribs can be provided. With the reinforcing ribs, the thickness of the handle 4 in the front-rear direction Y can be greater than that of the connecting rod 7. This can guide the stable operation of the opening module 30. As a result, the dimensional errors that may occur during operation can be minimized.

[0149] 7. A first virtual axis in the forward / backward direction Y, based on the first axis 42, and a second virtual axis in the up / down direction Z, also 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 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. In the second embodiment, when the first axis 42 and the second axis 71 have a defined range, the second axis 71 may overlap with the first virtual axis. Based on the above configuration, the opening module 30 can be configured more compactly.

[0150] 8. The handle 4 can rotate in a first direction with the first axis 42 as the center. The connecting rod 7 can rotate in a second direction with the second axis 71 as the center. In the first embodiment, the handle 4 and the connecting rod 7 can rotate in opposite directions. The handle 4 can rotate clockwise +X with the left-right direction X as the reference, and the connecting rod 7 can rotate clockwise +X with the left-right direction X as the reference. In the second embodiment, the handle 4 and the connecting rod 7 can rotate in directions different from each other. In the second embodiment, the handle 4 and the connecting rod 7 can rotate in directions that intersect each other. In the second embodiment, the handle 4 can rotate clockwise +X with the left-right direction X as the reference, and the connecting rod 7 can rotate clockwise +Z with the up-down direction Z as the reference. Due to the rotation directions of the handle 4 and the connecting rod 7 described above, the opening module 30 can be installed in a narrow space.

[0151] 9. A first virtual axis in the front-rear direction Y and a second virtual axis in the vertical direction Z are set with the first axis 42 as a reference. The first virtual axis can be used as the X-axis and the second virtual axis as the Y-axis to establish a four-quadrant system. For example, a YZ plane can be provided with the first axis 42 as a reference to establish a four-quadrant system. In this case, the contact portion C of the handle 4 and the connecting rod 7 can be located in at least one of the first quadrant and / or the second quadrant. In the first embodiment, the contact portion can be located in the second quadrant. In the second embodiment, the contact portion can move in both the first and second quadrants. According to the above configuration, an opening module 30 that is narrow in the front-rear direction Y can be provided. The width of the opening module 30 in the embodiment can be narrow in the front-rear direction Y and long in the vertical direction Z. The length of the opening module 30 in the vertical direction Z in the embodiment can be longer than the thickness in the front-rear direction Y.

[0152] 10. A contact portion C is provided between the handle 4 and the connecting rod 7. In this case, the distance between the contact portion and the first shaft 42 can be greater than the distance between the contact portion and the second shaft 71. Here, the distance can be based on the YZ plane. This allows for the amplification of the force passing through the handle 4. Consequently, an opening module 30 with a greater vertical than horizontal direction can be provided. As a result, a compactly constructed opening module 30 can be provided.

[0153] 11. A contact portion C is provided between the handle 4 and the connecting rod 7. At this time, the contact portion can move forward-Y when the opening module 30 is activated. By moving the contact portion, the opening module 30 can be installed in a narrow space.

[0154] 12. The connecting rod 7 may have a first region close to the second shaft 71 and a second region away from the second shaft 71. The first region may be thicker than the second region. Due to this configuration, deformation of the component when external forces are applied can be prevented. Therefore, accurate force transmission in terms of distance and direction can be ensured.

[0155] 13. The total length of the handle 4 can be longer than the total length of the connecting rod 7. Here, the length can be based on the YZ plane. By making the handle 4 longer, the force applied through the handle 4 can be significantly amplified. By making the handle 4 sufficiently long in one direction, a smaller opening module 30 can be provided.

[0156] 14. The point at which external force is applied to the first pressurizing part 43 is called the point of application (refer to...). Figure 13 (A). The contact portion between the handle 4 and the connecting rod 7 is referred to as C. The distance between the point of action A and the contact portion C can be shorter than the distance between the point of action and the first shaft 42. Here, the length can be based on the YZ plane. According to this configuration, the external force applied to the point of action can be amplified and applied to the connecting rod 7. Thus, the initial opening can be achieved with a smaller force.

[0157] 15. Establish a virtual line connecting the first axis 42 and the second axis 71. The first virtual line can refer to the shortest distance between the two axes. For example, in the second embodiment, the virtual line can be contained within the YZ plane. The angle formed by the virtual line and the front-back direction Y can be greater than the angle formed by the virtual line and the vertical direction Z. The virtual line can be nearly vertical. Here, verticality can be based on the YZ plane. As described above, the center point of motion of the handle 4 and the connecting rod 7 can be configured in the vertical direction Z. In this case, a narrower opening module 30 in the front-back direction can be formed. Here, it should be noted that the front-back direction is the thickness direction of the door. Thus, the door can be made thinner.

[0158] 16. A first virtual line is provided to connect the first axis 42 and the second axis 71. The first virtual line may refer to the shortest distance between the two axes. For example, in the second embodiment, the virtual line may be contained within the YZ plane. The point where external force is applied to the first pressure part 43 is called the point of action A. A contact part C is provided between the handle 4 and the connecting rod 7. A second virtual line is provided to connect the point of action and the contact part. The virtual line may be based on all YZ planes. The length of the first virtual line may be longer than the length of the second virtual line. According to this configuration, each contact part can be arranged in one direction. Thus, an opening module 30 that is long in the vertical direction can be provided.

[0159] 17. The elastic member can contact one side of the pusher 6 and one side of the support plate. In the first embodiment, the elastic member can push the pusher 6 forward-Y. This allows for accurate guidance of the pusher 6's movement. The elastic member 64 is horizontally positioned, thereby enabling accurate guidance of the pusher 6's movement.

[0160] 18. The centerline of the elastic member 64 can be located above the centerline of the pad 111. The center of gravity of the elastic member 64 can be located above +Z the center of gravity of the pad. According to this configuration, the pusher 6 and the pad can move without interference. According to the above configuration, a compact opening module 30 can be constructed.

[0161] Figure 21 Other embodiments combining the first and second embodiments are illustrated.

[0162] Reference Figure 21 (a). The handle 4, first shaft 42, second shaft 71, connecting rod 7, and pusher 6 in the first embodiment are shown. They may have a narrow width w1 and a high height H1.

[0163] Reference Figure 21 (b). This embodiment shows a handle 4, a first shaft 42, a second shaft 71, a connecting rod 7, and a pusher 6. As in the second embodiment, the second shaft 71 may extend in the vertical direction Z. The opening module 30 of this embodiment may have a narrow width w1 and a high height H1. The opening module 30 of this embodiment may show the pusher 6 in a position moved to the outside.

[0164] Reference Figure 21 (c). This embodiment shows a handle 4, a first shaft 42, a second shaft 71, a connecting rod 7, and a pusher 6. The handle 4 is similar to the handle 4 of the first embodiment, but may be longer in the left-right direction. The handle 4 is similar to the handle 4 of the first embodiment, but may be 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 opening module 30 of this embodiment may have a wide width w2 and a low height H2.

[0165] Reference Figure 21(d). This embodiment shows a handle 4, a first shaft 42, a second shaft 71, a connecting rod 7, and a pusher 6. The handle 4 is similar to the handle 4 of the first embodiment, but may be longer in the left-right direction. The handle 4 is similar to the handle 4 of the first embodiment, but may be 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. As in the second embodiment, the second shaft 71 may extend in the up-down direction Z. The opening module 30 of this embodiment may have a wide width w2 and a low height H2. The opening module 30 of this embodiment may show the pusher 6 in its outermost position.

[0166] Similar to the other embodiments, the handle 4 of the second embodiment can be provided in various forms similar to the handle 4 of the first embodiment.

[0167] <Third Embodiment>

[0168] The refrigerator of the third embodiment will now be described. The relationship between the cap 8, handle 4, shell 2, and front panel 31 of the refrigerator of the third embodiment may differ from that of other embodiments.

[0169] Figure 22 This is a cross-sectional view showing the cap recess of the third embodiment. This figure is a cross-sectional view of the refrigerator handle of the third embodiment viewed from the YZ plane. Figure 22 The virtual lines of the handle show the shape of the handle before it is rotated.

[0170] Reference Figure 22The cap recess 34 may include an opening for inserting a grip 5. The opening may occupy the entire area of ​​the cap recess. The cap recess 34 may include two side walls defining the left and right ends of the recess in the X direction. The cap recess may include a connecting portion connecting the two side walls. The connecting portion may have a lower wall 81 defining the lower part of the recess. The lower wall may extend in the Y direction. A rear wall 82 may be present in the rear portion of the lower wall. The rear wall may extend rearward +Y. The rear wall may extend upward +Z. The rear wall ensures sufficient space for inserting a user's fingers. Even if the width of the door in the Y direction is narrow, sufficient space for inserting a user's fingers can be ensured. The rear wall 82 may have at least one arcuate shape. The rear wall may move further rearward +Y as it approaches upward +Z. This ensures sufficient width of the cap recess for inserting a user's fingers. For example, the width of the cap recess 34 may be 12 mm. The arcuate shape of the rear wall may have at least two radii of curvature. The radius of curvature of the lower portion c1 of the rear wall can be greater than the radius of curvature of the upper portion c2 of the rear wall. This maximizes the heat insulation effect and ensures a clear insertion gap for the finger. At least one of the rear wall and / or lower wall of the cap recess can be securely fitted with the internal support plate 22. By providing the internal support plate on the rear and lower walls of the cap recess, the precise positioning of the opening module 30 and the gap can be made more accurate.

[0171] The cap 8 can be fastened to the outer panel 31. The cap can cover the outer panel. The upper front end of the cap can cover the upper end of the outer panel. The lower front end of the cap can contact the inner surface of the outer panel. The cap can be fastened to the housing 2. The lower front end of the cap can be fastened to the outer support plate 21. The upper end of the outer support plate can contact the inner surface of the outer panel. In the upper end of the outer support plate, the foaming component can flow into the contact portion with the inner surface of the outer panel.

[0172] The outer surface of the housing can be bent in accordance with the movement and shape of the handle 4 and the connecting rod 7. Through this bending, the housing can have a recess extending in the left-right direction X. The recess can extend in a straight line. The outer support plate 21 can be bent through the recess. At least two recesses can be provided. The recesses can be spaced apart in the vertical direction. The outer support plate can be bent in the vertical direction. The outer support plate can be inclined backward + Y towards the lower part. In the gap between the outer panel 31 and the outer support plate 21, the lower gap can be larger than the upper gap. The foaming component can flow from the lower side to the upper side through the gap between the outer panel 31 and the outer support plate 21. The foaming component can flow from below the opening module 30. Because the lower side of the gap between the outer panel 31 and the outer support plate 21 is wider, the foaming component can flow more smoothly. This is because high-pressure foaming components can flow through the wider lower gap.

[0173] The foamed component can flow into the recess. The housing can be firmly fixed by the foamed component. Due to the recess, the foamed component can solidify in a curved shape. Therefore, the bonding force between the foamed component and the housing can be further increased. The gap between the outer support plate 21 and the inner support plate 22 can be wider towards the top. Therefore, the foamed component can flow in smoothly. Therefore, it can be firmly positioned relative to the opening module 30 and the door. Therefore, the handle 4 can rotate smoothly about the first axis 42. Therefore, the connecting rod 7 can rotate smoothly about the second axis 71.

[0174] The foamed component may flow unevenly into the gap between the outer panel 31 and the outer support plate 21. This uneven flow can occur when the gap between the outer panel 31 and the outer support plate 21 is narrow, when the lower side of the gap is not wide, or when the bonding between the outer panel 31 and the outer support plate 21 is poor. In such cases, unfilled spaces containing unfilled foamed component may form in the gap between the outer panel 31 and the outer support plate 21. These unfilled spaces can create unevenness on the surface of the outer panel. This unevenness can cause long-term defects and reduced aesthetics. Figure 23 This is a surface view of the outer panel including the aforementioned unevenness. The unevenness can be removed using the opening module 30 of this embodiment.

[0175] <Fourth Embodiment>

[0176] The refrigerator of the fourth embodiment will be described below. The configuration for improving heat insulation and preventing condensation in the refrigerator of the fourth embodiment may differ from the features of the other embodiments.

[0177] Figure 24 This is a diagram showing the heat insulation effect around the opening module in the refrigerator of the fourth embodiment. Figure 24 The lines are isotherms. The closer the isotherms are, the more drastic the temperature change. Dramatic temperature changes can indicate significant heat leakage. Significant heat leakage can reduce insulation performance. Heat can move along the normal direction of the isotherms. Figure 24 It is the result of performing a simulation using a model.

[0178] Figure 24 The diagram shows a housing 2 into which the handle 4 is inserted, an outer panel 31, an inner panel 32, a cap 8, and a spacer 35. An insulation gap 38 can be provided inside the door. This insulation gap can accommodate at least a portion of the opening module 30. The insulation effect can be improved by filling the insulation gap 38 with foamed components, such as polyurethane foam. In addition to foamed components, the insulation gap can also be provided with vacuum components and porous components. At least two of these insulation components can also be provided simultaneously.

[0179] No insulation components are provided in the internal region. This internal region can be referred to as a weak insulation region. Because this weak insulation region narrows the door's insulation gap 38, it may reduce the door's insulation performance. Therefore, it is necessary to improve the insulation performance through this internal region. This ensures the refrigerator's insulation performance. The pressurizing section can be arranged in the same temperature region. The second heating section, the third heating section, and the fourth pressurizing section can be arranged in the same temperature region. All pressurizing sections can be arranged in the same temperature region. This allows the pressurizing sections to be unaffected by cold air. This reduces the temperature difference perceived by the user. The isotherm of the internal region can be wider than the isotherm of the insulation gap. With this configuration, heat transfer within the internal region itself can be reduced.

[0180] The electronic nose 39 can improve the heat insulation effect by cutting off the internal airflow. It can be seen that the isotherm does not pass through the electronic nose. The upper end of the spacer 35 can form the electronic nose. The spacer can control the shape of the isotherm. By controlling the shape of the isotherm, the heat insulation effect can be improved. The spacer can have a top surface on which the electronic nose 39 is disposed. The spacer can have an inner surface extending downward from the top surface. The spacer can have a bottom surface sloping forward from the lower end of the inner surface. The sloping angles of the top surface and the bottom surface can be different. The sloping angle of the bottom surface can be greater than the sloping angle of the top surface. Here, the sloping angle can refer to the angle sloping relative to the front-back direction Y. The inner surface of the spacer can have a predetermined length h1 along the vertical direction Z. To provide the electronic nose, the spacer can have a predetermined length along the front-back direction X. The vertical length d2 of the spacer can be longer than the front-back length d2. The lower end of the inner surface of the spacer can extend further downward than the lower end of the housing 2. The spacer can have a trapezoidal shape.

[0181] The isotherm of the insulation gap can have a portion extending to the lower right. Here, "lower right" can refer to the rear (+Y) and lower (-Z) directions. This lower right isotherm maintains sufficient spacing between isotherms. The wider spacing between isotherms improves insulation performance. Sufficient insulation is achieved even with a thin door. Heat can be transferred to the lower left due to the isotherms. The spacer can be positioned at the upper end of the inner panel 32. Here, "lower left" can refer to the front (-Y) and lower (-Z) directions. The shape of the heat transfer allows for a longer heat transfer length, thereby improving insulation performance.

[0182] The vertical plane (XZ plane) in the front-to-back direction Y can be the substantial extension direction of the wall that performs heat insulation for the door. The thickness of the door within the length of the front-to-back direction Y can perform heat insulation. The electronic nose 39 can perform heat insulation. The thickness of the door including the electronic nose can be referred to as the main heat insulation region. The main heat insulation region can be referred to as the heat insulation interval. The main heat insulation region can include a heat insulation wall region d1 and an electronic nose region d2. The heat insulation wall region can reduce heat conduction. The electronic nose region can reduce convective heat through flow. The electronic nose region can be the same as the length d2 of the partition in the front-to-back direction. The pusher 6 can be provided in the main heat insulation region. At least a portion of the pusher 6 can be provided in the electronic nose region. At least a portion of the pressurizing portion can be provided in the main heat insulation region. All of the pressurizing portions can be provided in the main heat insulation region. This improves heat insulation performance. The gasket can be provided in the main heat insulation region.

[0183] Figure 25This diagram illustrates the configuration used to prevent condensation from cold air in the door of the refrigerator in the fourth embodiment.

[0184] Reference Figure 25 The condensation point in the door can be the lowest temperature point on the outer surface of the door in contact with external air. This lowest temperature point c can be at least one location. The lowest temperature point c can be adjacent to the area where the cap 8 and the internal support plate 22 meet. In the opening module 30, the lowest temperature point c can be the area where the lower wall 81 and the rear wall 82 meet. In the opening module 30, the lowest temperature point c is a branch B of a cold air flow branch. This branch can refer to the cold air flowing in the internal support plate 22 branching to the lower wall 81 and the rear wall 82. A heat diffusion member 37 can be provided adjacent to the lowest temperature point c. The heat diffusion member can be a heat diffusion plate. The heat diffusion plate can promote heat transfer. The heat diffusion member can be made of metal sheet. The heat diffusion plate can also diffuse cold air. Due to the diffusion of cold air, the lowest temperature point can be prevented from dropping to the condensation temperature. The heat diffusion plate can be provided on the back side of the rear wall 82 adjacent to the lowest temperature point c. The heat diffusion plate may be disposed on the bottom surface of the lower wall 81 adjacent to the lowest temperature part c. The heat diffusion plate may be disposed on at least one of the back and / or front of the internal support plate 22 adjacent to the lowest temperature part c.

[0185] When the door is thin, condensation at the lowest temperature location can be extremely severe. The heat diffusion plate prevents condensation. As an example, the figure shows the heat diffusion plate 37 disposed on the outer support plate 21, lower support plate 23, inner support plate 22, rear wall 82, and upper wall 83. This allows external heat to be transferred to the lowest temperature location c. The arrows indicate the direction of heat transfer. Heat can be conducted from the outside air via the heat transfer path through the outer support plate 21, lower support plate 23, and inner support plate 22. Heat can also be conducted from the outside air via the heat transfer path through the rear wall 82 and upper wall 83. Heat can also be conducted from the heater via the heat transfer path through the rear wall 82 and upper wall 83. Here, the heater can be disposed on the cabinet 11. The heater prevents condensation on the cabinet. The heater prevents condensation on both the cabinet and the door. The heater can be disposed on the partition wall separating the storage space. Here, the partition wall can be the partition wall separating the refrigerator compartment and the freezer compartment.

[0186] <Fifth Embodiment>

[0187] The refrigerator of the fifth embodiment will now be described. The lateral length of the cap recess and the pushing member 6 of the fifth embodiment may differ from the features of the other embodiments.

[0188] Figure 26This is a diagram comparing the thickness of the door in the fifth embodiment and the door in the comparative example. Figure 26 (a) is a comparative example where the concave part of the cap is longer on the left and right and has a single pusher. Figure 26 (b) is a fifth embodiment in which the concave portion of the cap is shorter on the left and right sides and has at least two pushers.

[0189] Reference Figure 26 In the fifth embodiment, the length b1 of the front-to-back direction Y of the door end is less than the length a1 of the front-to-back direction Y of the door end in the comparative example. This allows for a further increase in the internal volume of the storage space. The problem of thinning insulation thickness at the door end can be eliminated using the various solutions described above. In the embodiment, the length b2 of the left-to-right direction X of the cap recess can be greater than the length a2 of the left-to-right direction X of the cap recess in the comparative example. This shortens the area where the insulation thickness is narrowed.

[0190] In the comparative example, the initial opening of the door may be uneven due to the single pusher 6. The force concentrated in one place may not be sufficient for the initial opening of the door. Because the force applied to a single component is large, there is a problem of increased size for each component. In the embodiment, at least two pushers 6 can be provided. In the embodiment, two pushers 6a and 6b can be provided on the left and right sides. The pushers 6 can be symmetrically arranged in the left-right direction X. The pushers 6 can be positioned adjacent to the dividing points when the door is divided into three equal parts in the left-right direction X. The pushers 6 can be positioned in the middle region when the door is divided into three equal parts in the left-right direction X. The pushers 6 can be positioned adjacent to the second and fourth dividing points from one end when the door is divided into six equal parts in the left-right direction X. The figure shows the pusher adjacent to the second dividing point from the left. The pushers 6 can be positioned in the third and fourth regions from one end when the door is divided into six equal parts in the left-right direction X. According to the above configuration, the door can be initially opened using minimal external force. Therefore, the force applied to each component can be reduced. Therefore, each component can be formed thinner and longer. Therefore, a smaller opening module 30 can be provided.

[0191] The comparative example can be included within the scope of the present invention. In the comparative example, the pusher 6 can be a single pusher 6 positioned in the middle of the left-right direction of the door. The single pusher 6 can be achieved by individually constructing the connecting rod 7, changing the position of the shaft to the middle, changing the position of the handle 4, or avoiding interference by changing the vertical position of the pusher 6.

[0192] <Sixth Embodiment>

[0193] The following describes the refrigerator according to the sixth embodiment. The left-right length of the cap recess, the pusher 6, and the handle 4 in the sixth embodiment may differ from the features of other embodiments.

[0194] Figure 27 This is a diagram comparing the thickness of the door in the sixth embodiment and the door in the comparative example. Figure 27 (a) is a comparative example where the cap recess has a shorter length on the left and right and two pushers. Figure 27 (b) is a sixth embodiment in which the cap recess has a longer left and right side and at least two pushers. Figure 27 (a) can be an embodiment of the door proposed in the fifth embodiment. Compared with the comparative example of the fifth embodiment, the cap recess of the sixth embodiment can be shorter along the left and right sides.

[0195] Reference Figure 27 The front-to-back lengths of the door ends in the comparative example and the sixth embodiment can be the same. The length b2 of the left-to-right direction (X) of the cap recess in the sixth embodiment is less than the length a2 of the front-to-back direction (Y) of the door in the comparative example. Therefore, a shorter area with narrower insulation thickness can be formed. When the cap recess is longer in the left-to-right direction, user accessibility can be improved. The user can approach not only the center of the door but also any position of the cap recess, which is wider in one direction.

[0196] In the comparative example, even using two pushers 6, the initial opening of the door may not be smooth. This is because the positions of the guide rails applying the static friction force to the door and the pushers 6 become farther apart. In the embodiment, at least two pushers 6 can be positioned further outward in the left-right direction. In the embodiment, two pushers 6a and 6b can be provided on the left and right sides. The pushers 6 can be symmetrically arranged along the left-right direction X. The position of the pushers 6 can be located at the maximum outward of the left-right direction X of the door. Thus, the pushers 6 can be adjacent to the pair of guide rail portions applying the static friction force. The pushers 6 can be located outward of the cap recess 34. This is because interference may occur if there are portions of the pushers 6 and the cap recess aligned in the front-back direction Y. The right pusher 6 of the pair of pushers 6 can be positioned further to the right than the cap recess 34. The left pusher 6 of the pair of pushers 6 can be positioned further to the left than the cap recess 34. The pushers 6 can interfere with the hinge 14 in the vertical direction Z. The hinge allows the first doors 12 and 13 to rotate. The hinge can protrude vertically along the first doors 12 and 13. This is because interference may occur when there is a portion where the pusher 6 and the hinge are aligned vertically (Z-direction). The right pusher 6 of a pair of pushers 6 can be positioned further to the left than the hinge 14. The left pusher 6 of a pair of pushers 6 can be positioned further to the right than the cap recess 34. The length l4 of the pusher 6 from the center of the door along the left-right direction can be longer than the length l3 from the pusher 6 to the left-right end of the door. Therefore, the position of the pusher 6 can be maximized to be adjacent to the guide rail.

[0197] The handle 4 can be located at the center of the cap recess 34. The handle 4 can be extended in the left-right direction X. The longer the handle 4, the more conveniently the user can access it. The longer the cap recess, the longer the handle 4 should be. The length l1 from the center of the cap recess to the end of the handle 4 in the left-right direction can be longer than the length l2 from the end of the handle 4 to the left-right end of the cap recess.

[0198] As described above, in order to make the handle 4 and the pusher 6 adjacent, the configuration of the handle 4 can be set differently in terms of features. Figure 28 This is a perspective view of the components related to the handle that can be applied to the sixth embodiment. Figure 28 The components can be found Figure 21 Changes occur in the components of the handle 4, the first shaft 42, the second shaft 71, the connecting rod 7, and the pusher 6.

[0199] Reference Figure 28 The configuration of the handle 4, first shaft 42, second shaft 71, connecting rod 7, and pusher 6 in the embodiment is similar to... Figure 21 In contrast, the end of handle 4 and push member 6 can be adjacent. In this embodiment, the end of handle 4 is adjacent to... Figure 21 In contrast, handle 4 can be positioned longer along the left-right direction X. The end of the connecting rod 7 in the embodiment is... Figure 21 In contrast, the handle 4 can be provided to be longer along the left-right direction X. In this embodiment, the second region 41 can be reduced in the left-right direction X. The second region in this embodiment can have the left-right direction region of the second pressure part 44. The second region other than the left-right direction region of the second pressure part 44 can be deleted. According to this embodiment, the effect of reducing the torsional force of the handle 4 can be obtained.

[0200] <Seventh Embodiment>

[0201] The refrigerator of the seventh embodiment will now be described. The relationship between the first axis 42 and the second axis 71 in the seventh embodiment may differ in features from those in other embodiments.

[0202] Figure 29 The following are side sectional views of the door showing the positional relationship between the first axis 42 and the second axis 71 of the refrigerator in the seventh and eighth embodiments. (a) shows the positional relationship between the first axis 42 and the second axis 71 in the first embodiment, and (b) shows the positional relationship between the first axis 42 and the second axis 71 in the seventh embodiment.

[0203] Reference Figure 29 In the first embodiment, the second axis 71 may be positioned forward-Y relative to the first axis 42. The second axis 71 may be closer to the user than the first axis 42. This allows the user to operate the handle with less force.

[0204] In the seventh embodiment, the second axis 71 and the first axis 42 may be located at the same position in the front-rear direction Y. In the seventh embodiment, at least a portion of the second axis 71 and the first axis 42 may be aligned in the vertical direction Z.

For example, it can be bent downward in the upward direction Z. In the seventh embodiment, the upper end of the connecting rod can be bent backward. In addition to the connecting rod, the shape of at least one of the handle and / or the pusher can be changed. Thus, the opening module can be installed in a narrow space.

[0206] According to this embodiment, the outer panel 31 and the outer support plate 21 can be adjacent in the front-to-back direction (Y direction). Heat from the outer panel can be transferred to the outer support plate. This prevents condensation on the opening module 30. In this embodiment, the flowability of the foamed component may deteriorate. To prevent this, a bend-resistant film can be attached to the outer surface of the outer panel.

[0207] <Eighth Embodiment>

[0208] The refrigerator of the eighth embodiment will now be described. The relationship between the first axis 42 and the second axis 71 in the eighth embodiment may differ in features from those in other embodiments.
