Description

Technical Field

[0001] This invention relates to refrigerators. Background Technology

[0002] A refrigerator has a storage space capable of preserving food at low temperatures. Refrigerators utilize cold air generated through heat exchange with the refrigerant circulating in the refrigeration cycle. In recent years, refrigerators have gradually become larger and / or more multifunctional in response to changes in dietary habits and the trend towards more sophisticated products. Furthermore, various types of refrigerators are constantly emerging to provide convenience for users and to efficiently utilize internal space.

[0003] The storage space of a refrigerator can be opened and closed via a door. Furthermore, refrigerators can be classified into various types based on the configuration of the storage space and the structure of the door for opening and closing it. For example, a refrigerator door can be opened and closed by rotating or sliding the door out.

[0004] The door can be opened and closed by the user. However, if the door is large and heavy, if there is a significant pressure difference between the inside and outside of the refrigerator, or if the door seal has a strong magnetic force, the user may find it difficult to open or close the door. For example, more force may be required to open the door. This may cause inconvenience to the user.

[0005] Patent Publication No. 10-1528729 (hereinafter referred to as "Patent 729") discloses a refrigerator with a door opening device, which initially opens the door by pushing the main body. The door opening device of Patent 729 includes a handle for user operation, a rotating part having a rotating shaft and an actuating part, and a pushing unit that slides the actuating part to push the main body.

[0006] The door opening device of the "729" patent operates in a state where the rotating part and the pushing unit are in direct contact, therefore the pushing unit and at least a part of the rotating part need to be arranged at the same height.

[0007] While increasing the length of the actuating part allows for a larger height difference between the gripping part and the pushing unit, the following problems exist: the force required to rotate the gripping part increases, and the door becomes thicker in the front-to-back direction to ensure space for the rotating part to rotate.

[0133] The embodiments disclosed in this specification will now be described in detail with reference to the accompanying drawings, and the same or similar components will be given the same reference numerals regardless of the drawing numbers, and repeated descriptions thereof will be omitted.

[0134] The suffixes “module” and “section” used in the following description for the constituent elements are assigned or used interchangeably only for the convenience of writing the specification, and do not have the meaning or function of distinguishing between them.

[0135] Furthermore, in the process of describing the embodiments disclosed in this specification, if it is determined that a detailed description of related well-known technologies would obscure the technical concept of the embodiments disclosed in this specification, a detailed description thereof will be omitted. Moreover, the accompanying drawings are only for ease of understanding of the embodiments disclosed in this specification and should not be used to limit the technical concept disclosed in this specification. Rather, they should cover all modifications, equivalents, and even substitutions included within the scope of the invention's concept and technology.

[0136] Terms containing ordinal numbers such as "first" and "second" may be used to describe multiple constituent elements, but the constituent elements are not limited by the terms. The terms are used only for the purpose of distinguishing one constituent element from other constituent elements.

[0137] When a constituent element is mentioned as being "connected" or "linked" to another constituent element, it should be understood that it may be directly connected or linked to that other constituent element, but there may also be other constituent elements between them. Conversely, when a constituent element is mentioned as being "directly connected" or "directly linked" to another constituent element, it should be understood that there are no other constituent elements between them.

[0138] Unless the context clearly indicates a different meaning, a singular expression includes a plural expression.

[0139] Figure 1 This is a perspective view of the refrigerator in the embodiment. (Refer to...) Figure 1 The refrigerator 1 may include a cabinet 11 forming a storage space. The storage space may be located inside the cabinet 11. The refrigerator 1 may include doors 12, 13, and 20 for opening and closing the storage space. The refrigerator may include a thermal compartment. Hereinafter, the interior of the storage space will also be referred to as the "refrigerator interior".

[0140] The storage space of the housing 11 can be divided vertically by partitions. A refrigerator compartment can be formed in the upper part, and a freezer compartment can be formed in the lower part. However, the present invention is not limited to the refrigerator and freezer compartments described above. For example, the lower part of the storage space can also be a refrigerator compartment.

[0141] The doors may include first doors 12 and 13 for opening and closing the refrigerator compartment. First doors 12 and 13 may include a left door 12 and a right door 13. The first doors may be mounted to the housing 10 using hinges 14. The first doors can be opened and closed by rotating the refrigerator compartment.

[0142] The door may include a second door 20 for opening and closing the freezer compartment. The second door 20 may be slidably mounted to the cabinet 11. During the sliding action, the cabinet can be extended or retracted. The freezer compartment can be opened and closed by extending or retracting the second door 20. The second door 20 may include a door portion and a frame disposed on the back of the door portion. The second door 20 may be referred to as a drawer door 20.

[0143] The second door 20 may include a track 29 extending in the front-to-back direction. A track 21 may be provided behind the door portion of the second door 20. The track can guide the introduction and exit of the second door.

[0144] Contact members may be provided on the first doors 12 and 13. A contact member may be provided on the second door 20. The user can operate the second door 20 through the contact members. By operating the contact members, the door 20 can be pushed out from the cabinet 11. Hereinafter, the "contact member" will also be referred to as the "operating part". For example, the contact member can overcome door load, pressure difference between the inside and outside of the refrigerator, and the sealing gasket 111 (see reference). Figure 6 The door is opened by the gravitational force generated by the opening of the door 20. In this case, the opening of the door can refer to the initial opening. The sealing gasket 111 may contain a magnetic material, and the gravitational force may refer to magnetic force. Alternatively, the sealing gasket 111 may be able to seal the space between the door 20 and the housing 11, and the gravitational force may be the gravitational force generated by the pressure difference between the inside and outside of the storage space of the housing 11 when the door 20 is opened.

[0145] The opening of the door is described below. Door opening can include both initial opening and non-initial opening. Initial opening refers to the initial opening of the door 20. Non-initial opening refers to door opening after the initial opening has ended.

[0146] In both initial and non-initial opening, the door load acts as a resistance. This resistance can be considered the force that prevents the door 20 from opening. Initially, the pressure difference between the inside and outside of the refrigerator plays a significant role in the initial opening. During the initial opening process, the resistance caused by the pressure difference between the inside and outside of the refrigerator can disappear rapidly. The magnetic force of the sealing gasket 111 can function throughout the entire initial opening period. The magnetic force of the sealing gasket 111 can gradually decrease throughout the entire initial opening period.

[0147] 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 20 and the housing 11 can be initially opened. For example, a user can operate the contact member with their finger to perform the initial opening. Subsequently, the user's arm can move the door. The user can touch, grasp, push, pull, and / or press the contact member. An automatic mechanism can be used to activate the contact member instead of the user. The contact member can be located at the corners of the first doors 12, 13 and the second door 20. The contact member can be located at the upper end of the second door 20.

[0148] The embodiment uses a bottom-freezer refrigerator with the freezer compartment located at the bottom as an example. The concept of this invention can be applied to other types of refrigerators. The concept of this invention can also be applied to other types of doors.

[0149] In the following embodiments, the case where the contact member is provided in the second door will be described as an example. In the following description, when referring to a door, the second door is preferred. The door may also be the first door.

[0150] Figure 2 This is an exploded 3D view of the door. Figure 3 yes Figure 2 A detailed exploded 3D view of the activation module.

[0151] Reference Figure 2 and Figure 3 The door 20 may include an outer panel 31 facing the exterior (i.e., front) of the housing 11 and an inner panel 32 facing the interior (i.e., rear) of the housing. The outer panel 31 may be made of metal. The inner panel 32 may be made of resin. Hereinafter, the outer panel 31 will also be referred to as the front panel. The inner panel 32 may be a door lining.

[0152] The door 20 may include a bottom 311 that protects the lower part. The two sides of the door may be portions extending from either the outer panel 31 or the inner panel 32. For example, the two sides may extend rearward from the front two ends of the outer panel 31.

[0153] The door 20 may include a cap 8 that provides a top surface for the door 20. The cap 8 can protect the upper part of the door 20.

[0154] The cap 8 may include a cap recess 34. The cap recess 34 may have a downwardly recessed structure to allow 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 into the interior of the cap 8. The cap recess 34 may include a portion recessed downwards towards the door 20.

[0155] The door 20 may include an opening module 30 capable of being linked with the contact member. The opening module may accommodate at least a portion of the contact member.

Figure 4 A first component can be provided by fastening the opening module and the cap. A second component can be provided by fastening the outer panel, the inner panel, and the bottom. The second component can be fastened to the top surface of the first component. With the above structure, an insulated space inside the door can be achieved.

[0157] Reference Figures 2 to 4Foamed components can be filled in the intervals defined by the spacing between the components. The foamed components can 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 sides. The foamed components can be filled in the external space of the opening module. The foamed components can be filled between the opening module and the outer panel, between the opening module and the inner panel, between the opening module and the bottom, between the opening module and the cap, and / or between the opening module and the sides. The foamed components can be PS (Polystyrene) or porous materials. Vacuum insulation components can be used in place of the foamed components or used together with them.

[0158] The cap 8 can be fastened to at least one of the inner panel and the outer panel. The cap can be fastened to at least one of the inner panel and the outer panel while the opening module 30 is fastened to it. The cap can be fastened to the upper end of at least one of the inner panel and the outer panel. The cap can be fastened to at least one of the inner panel and the outer panel using protrusions and grooves. The inner panel and the outer panel can have upper ends of the same height. For the cap to be fastened, the inner panel and the outer panel may not provide recesses or protrusions in the front-rear direction Y. For the cap to be fastened, the inner panel and the outer panel may not provide recesses or protrusions in the vertical direction Z. At least one of the gaps between the cap and the inner panel and between the cap and the outer panel can be filled with foam material. The cap and the opening module can be securely positioned.

[0159] 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 track 29 can extend inward toward the inner side of the inner panel 32. Prescribed fastening members can fasten the track and the inner panel to each other. Prescribed fastening members can fasten the track mounting part and the track. The prescribed fastening members can be the same. The track mounting part 321 can be fastened to the inner panel. The track mounting part can make the track and the inner panel securely fastened. Through the track mounting part, even if the door thickness (Y-axis length) is thin, the track can be strongly fixed to the inner panel. The track mounting part 321 can be aligned with the track groove 33.

[0160] The opening module 30 can initially open the door through the action of the contact member. Figure 5 This is a perspective view used to illustrate the function of the opening module. Figure 5This is a diagram showing the state after the cover and housing of the opening module have been removed.

[0161] 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. The grip may be fastened to the handle. If the grip is absent, the handle may serve as the contact member. A component that actuates the opening module through external force may be referred to as a contact member.

[0162] The handle can rotate when the grip portion moves forward -Y. The handle can rotate in a first direction with reference to a first axis 42. The handle can rotate the connecting rod 7. The connecting rod can rotate in a second direction with reference to a second axis 71. The first direction and the second direction can be opposite directions. The connecting rod can push the push rod 6 backward +Y. The push rod and the housing can perform action / reaction movements. When the push rod pushes the housing, the door can be initially opened. Here, the housing may include components that do not move relative to the door movement.

[0163] The activation module is described in detail.

[0164] The opening module 30 may include a handle 4, to which an external force is applied. The handle may have a portion extending in the vertical direction Z. The handle may have a first region 40 at its center. The handle may have a second region 41 on the side 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 increasing the lateral length w1 of the first region, the torsion of the handle can be reduced. The torsion of the handle may occur when the handle is rotated. The greater the torsion of the handle, the further the grip and the push rod are in the left-right direction X. To further reduce the torsion of the handle, a plurality of reinforcing ribs 45 may be provided on the handle. The reinforcing ribs in the second region may be more densely packed than the reinforcing ribs in the first region. This further reduces the torsion of the handle. 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 higher so that an external force is applied to the first region. The height of the first region may be higher so that a larger force can be obtained with a smaller external force using the principle of leverage. The external force can be adjusted to an appropriate level according to the lever principle. A first shaft 42 may be provided on the lower side of the handle. The first shaft may extend in the left-right direction (X direction). The upper part of the first region may be a first pressure part 43. The upper part of the second region may be a second pressure part 44. If the first pressure part is pushed, the handle rotates about the first shaft. If the handle rotates, the second pressure part may push the connecting rod. The first shaft 42 may be supported by a cover 3. The cover may support the handle on both sides of the first shaft.

[0165] The connecting rod 7 can be located on the left or right side of the handle. The connecting rod 7 can rotate about the second shaft 71. The connecting rod may include a third pressure part 72 on the lower side of the second shaft. The connecting rod may include a fourth pressure part 73 on the upper side of the second shaft. The third and fourth pressure parts may have portions extending in the vertical direction Z. The third and fourth pressure parts may provide reinforcing ribs. The reinforcing ribs can prevent deformation of the connecting rod. The lengths of the third and fourth pressure parts may be different from each other. The lever effect can be achieved by adjusting the lengths of the third and fourth pressure parts. The second pressure part can push the third pressure part. If the second pressure part is pushed, the connecting rod can rotate about the second shaft. If the connecting rod rotates, the third and fourth pressure parts can rotate together. The fourth pressure part can push the push rod 6. At least two connecting rods may be provided. A pair of connecting rods may be provided. The connecting rod can initially open the door with a balanced force. One end of the second shaft 71 may be supported on the cover 3. The other end of the second shaft 71 can be supported in the housing.

[0166] The push rod 6 can be located between the opening module 30 and the housing 11. The push rod can be the point of action for the door and the housing. The push rod can have an outer end 61 extending in the vertical direction Z. Even if the fourth pressure part 73 changes position during rotation, the outer ends can remain in contact with each other. The push rod can have an extension 62 extending in the front-rear direction Y. The extension can increase the effective length of the push rod. An inner end 63 can be present at the rear end of the extension. The inner end can contact the housing 11. If the push rod is pushed rearward, the inner end can push the housing. The inner end can be referred to as the pushing 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 greater than the height of the extension. The fourth pressure part 73 can push the outer end. If the outer end is pushed, the push rod can move rearward as a whole. The push rod can push the housing. The cover 3 can guide the push rod. The cover may provide at least one rib to guide the movement of the push rod. The rib may extend in the forward-backward direction (Y). The force applied to the push rod can be adjusted by the first lever action of the handle and the second lever action of the connecting rod.

[0167] The first pressurizing part 43 and the fourth pressurizing part 73 can be located in the upper direction +Z relative to the first rotation axis. The first pressurizing part 43 and the fourth pressurizing part 73 can be located in the same direction relative to the first rotation axis. The first pressurizing part 43 and the fourth pressurizing part 73 can be located in the upper direction +Z relative to the second rotation axis. The first pressurizing part 43 and the fourth pressurizing part 73 can be located in the same direction relative to the second rotation axis. The first pressurizing part can be a pressurizing part that initiates external force. The fourth pressurizing part can be a pressurizing part that ultimately pushes the push rod. The second pressurizing part 44 and the third pressurizing part 72 can be located in the upper direction +Z relative to the first rotation axis. The second pressurizing part 44 and the third pressurizing part 72 can be located in the lower direction -Z relative to the second rotation axis. The first rotation axis can be located further down than the second rotation axis. Based on the above configuration, the width of the opening module in the front-rear direction Z can be small. Therefore, the front wall of the door can be constructed thinner. Thus, the thermal insulation length can be longer. This can improve the heat insulation effect.

[0168] The grip portion 5 can be located on the upper part of the handle 4. The user can easily access the grip portion. The external force acting on the grip portion can be amplified by the first and second lever actions. For example, even with a small force applied by the user, the door can be initially opened. Initial opening of the door can be achieved with a small force applied by the fingers.

[0169] The housing 2 can accommodate at least a portion of the handle. The housing can guide the movement of the handle. The housing can guide the position of the handle. 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 can connect the lower parts of the internal support plate and the external support plate front and rear. The side of the housing may include an opening 25. The second region 41 can extend laterally through the opening. A bushing 26 may be included above the opening 25. The bushing can support the second shaft 71. The bushing may include a cylindrical structure supporting the inner side of the second shaft. The upper part of the housing may be open. The handle 4 can be assembled through the upper part of the housing. The outer surface of the housing may be curved in accordance with the movement and shape of the handle and the connecting rod. The housing may have a groove extending in the left-right direction X. A foaming member can flow into the groove. The housing can be securely positioned by the foaming member. The gap between the outer support plate 21 and the inner support plate 22 can widen as it approaches the top. This allows for smooth flow of the foaming component. Therefore, the handle can rotate smoothly about a first axis. Therefore, the connecting rod can rotate smoothly about a second axis. The foaming component can flow in from the lower side of the opening module 30. The upper part of the inner support plate 22 may include a connector 24 extending rearward +Y. The connector can guide the position of the opening module 30 and the cap 8. For example, the opening module and the cap can be assembled using the connector. The connector 24 can guide the movement of the push rod.

[0170] 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 relative to the outside. The cover can block the inflow of the foaming component. The cover can have bushings supporting the first and second shafts. The cover can guide the movement of the push rod.

[0171] The second axis can be located further forward (Y position) than the first axis. The second axis can be located further upward (Z position) than the first axis. The second axis can be closer to the user than the first axis. 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.

[0172] Figure 6 This is a diagram illustrating the structure of the pressurizing section. Figure 6 (a) is along Figure 1 A sectional perspective view cut along line 6a-6aˊ. Figure 6 (b) is along Figure 1A sectional perspective view cut along line 6b-6bˊ. Figure 6 (b) is along Figure 1 A sectional perspective view cut along line 6b-6bˊ. (Refer to...) Figure 6 Explain the operation of the pressurization section.

[0173] In a stationary state, at least one of the handle and the connecting rod can be in contact with at least one of the inner support plate 22, the outer support plate 21, and the cap 8. In a stationary state, the handle can be in contact with at least one of the cap 8 and the inner support plate 22. In a stationary state, the connecting rod can be in contact with the outer support plate 21. Under the action of external force, the grip 5 can push the first pressing part 43. The first pressing part can rotate. The first pressing part and the second pressing part 44 can rotate in the same direction. The second pressing part can push the third pressing part 72. The second pressing part and the third pressing part can rotate in different directions. The third pressing part can rotate. The third pressing part and the fourth pressing part 73 can rotate in the same direction. As described above, the pressing part can rotate around the first axis and the second axis. The fourth pressing part 73 can push the push rod 6. The pressing end 63 of the push rod can push the box body. The pressing end can push the partition wall of the storage compartment. The housing may be the outermost panel of the housing. The pressing end may push the outside of the sealing gasket 111.

[0174] 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 to the height h1 of the first region 40 can be greater than the ratio (h2 / w12) of the thickness w12 to the height h2 of the second region 41. Therefore, the torsion of the second region can be further reduced. When the handle is actuated, the second region can generate a greater torque than the first region.

[0175] Figure 7 This is a diagram showing a comparison of the operation of the activation module before and after. Figure 7 (a) and Figure 7 (b) can be in a static state. Figure 7 (b) 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.

[0176] Reference Figure 7When the module is opened, handle 4 can rotate counterclockwise around the first axis. When the module is opened, linkage 7 can rotate clockwise around the second axis. When the module is opened, the push rod can move forward. An elastic member 64 can be provided to control the movement of the push rod. The elastic member can return the push rod to a stationary state. The elastic member can connect the outer end 61 of the push rod and the cover 3.

[0177] A sealing gasket groove 36 can be provided on the lower side of the cap groove 34. The sealing gasket 111 can be fixed in the sealing gasket groove 36. The door 20 can provide a dam 35 at the rear +Y of the opening module. The dam can enhance the insulation thickness of the wall of the opening module. The dam can provide an energy nose. The energy nose can improve the insulation effect by blocking the airflow in the storage space.

[0178] Figure 8 This shows the tightening process of the opening module. Figure 8 The diagrams in the diagrams represent the fastening of each component.

[0179] Figure 8 (a1) shows the elastic member 64 fastened to the push rod 6. The elastic member can guide the push rod to a rest position. The elastic member can pull the push rod forward. Figure 8 (a2) shows the handle 4 being fastened to the housing 2. Figure 8 (b) shows the push rod being secured to the cover 3 and the connecting rod being secured to the cover. The movement of the push rod can be guided by the cover. The elastic member can be clamped between the push rod and the cover. At least a portion of the connecting rod can be located in front of the push rod. One side of the second axis of the connecting rod can be supported by the cover. The state in which the various components are secured to the cover is referred to as the cover assembly.

[0180] Figure 8 (a2) shows the second region 41 on the left side of the handle moving deeply to the left through the opening 25 on the left-X side. At this time, the handle can be in a tilted position towards the upper right. It can be in a state where the grip portion is firmly attached to the handle. Then, the handle can be aligned horizontally. The handle can be moved to the right. Through this action, the second region 41 on the left side of the handle can be moved to the right through the opening 25 on the left side. Through this action, the second region 41 on the right side of the handle can be moved to the right through the opening 25 on the right-X side. Through the above process, the handle can be aligned to an accurate position within the housing. The state in which the handle is placed within the housing is referred to as the handle assembly.

[0181] Figure 8Figure (c) shows a diagram of the cover assembly and the handle assembly being fastened. The two assemblies can be fastened by inserting protrusions into recesses. The cover can be fastened to both sides of the housing 2. The first shaft can be supported by the cover. The second shaft can be supported by the cover. The first shaft can be supported only by the cover. Each of the second shafts can be supported by both the cover and the housing.

[0182] Figure 8 Figure (d) shows the opening module and cap fastening. The cap can be fastened to the upper end of the opening module. The cap can be fastened to the connecting rod. The cap can be fastened to the connector. Each component can be fastened by inserting a protrusion into a groove. The cap groove 34 and the grip 5 can be aligned in a precise position. The unit after the cap and the opening module are fastened can be fastened to the panels 31, 32. The unit can be fixed by fastening the cap 8 to the panels 31, 32. The opening module may not be fixed to the panels. The internal support plate 22 may not be in contact with the panels 31, 32.

[0183] Figure 9 This is a diagram used to illustrate the cap groove.

[0184] Reference Figure 9 The cap recess 34 may include an opening for the grip portion 5 to enter. The opening may be provided on the front of the cap recess. The cap recess 34 may include two side walls defining the two ends of the recess in the left-right direction X. 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 front-back direction Y. A rear wall 82 may be provided on 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 spacing for user finger insertion. Even if the width of the door in the front-back direction Y is narrow, sufficient spacing for user finger insertion can be ensured. The rear wall 82 may have at least one arcuate shape. The rear wall may be formed such that it shifts further rearward +Y towards the upper +Z. This ensures sufficient width of the cap recess for user finger insertion. 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 larger than the radius of curvature of the upper portion c2 of the rear wall. This maximizes the heat insulation effect and ensures proper finger insertion spacing. At least one of the rear and lower walls of the cap recess can be securely fitted with the internal support plate 22. By placing the internal support plate on the rear and lower walls of the cap recess, the opening module and the cap can be positioned accurately.

[0185] Figure 10This is a diagram showing the heat insulation effect around the door. Figure 10 The lines shown represent isotherms. Closely spaced isotherms indicate drastic temperature changes. Dramatic temperature changes can indicate significant heat leakage. Significant heat leakage can reduce insulation performance. Heat can travel towards the normal direction of the isotherms. Figure 10 It is the result of simulation through modeling.

[0186] Figure 10 The diagram shows a housing 2 for the handle 4, an outer panel 31, an inner panel 32, a cap 8, and a dam 35. The interior of the door may provide an insulating space 38. This insulating space can accommodate at least a portion of the opening module 30. The insulating space 38 may be filled with a foam component, such as a polyurethane foam component, thereby improving insulation. In addition to the foam component, the insulating space may also contain insulating components of vacuum components and porous components. At least two of these insulating components may also be used.

[0187] The inner region where the housing 2 and the cap 8 are placed can be referred to as the internal region. The internal region does not provide insulation. This internal region can be referred to as a low-insulation region with poor insulation performance. This low-insulation region narrows the door's insulation gap 38, potentially causing a decrease in the door's insulation performance. It is necessary to improve the insulation performance of the internal region. This ensures the refrigerator's insulation performance. The pressurizing sections can be located in the same temperature range. The second, third, and fourth pressurizing sections can be located in the same temperature range. All pressurizing sections can be located in the same temperature range. Therefore, the pressurizing sections are 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. This configuration reduces heat transfer within the internal region itself.

[0188] The energy nose 39 can improve the heat insulation effect by blocking the internal airflow. It can be confirmed that the isotherm does not pass through the energy nose. The upper end of the embankment 35 can generate the energy nose. The embankment can control the shape of the isotherm. By controlling the shape of the isotherm, the heat insulation effect can be improved. The embankment can have a top surface that provides the energy nose 39. The embankment can have an inner surface extending downward from the top surface. The embankment can have a bottom surface that slopes forward from the lower end of the inner surface. The slope angles of the top surface and the bottom surface can be different. The slope angle of the bottom surface can be larger than that of the top surface. Here, the slope angle can refer to the angle of inclination relative to the front-back direction Y. The inner surface of the embankment can have a predetermined length h1 in the vertical direction Z. The embankment can have a predetermined length in the front-back direction X to provide the energy nose. The vertical length d2 of the embankment can be longer than the front-back length d2. The lower end of the inner surface of the embankment can extend further downward than the lower end of the shell 2. The embankment can be trapezoidal in shape.

[0189] The isotherms of the insulation interval may have a portion extending in a downward-right direction. Here, the downward-right direction can refer to the direction towards the rear (+Y) and downward (-Z). Sufficient isotherm spacing can be maintained through the downward-right isotherms. Widening the spacing between isotherms improves the insulation effect. Even with a thin door, sufficient insulation performance can be achieved. Heat transfer in a downward-left direction may occur according to the isotherms. The embankment may be provided at the upper end of the inner panel 32. Here, the downward-left direction can refer to the direction towards the front (-Y) and downward (-Z). The shape of this heat transfer results in a longer heat transfer length, thereby improving insulation performance.

[0190] The vertical plane (XZ plane) in the front-to-back direction Y can be the actual extension direction of the wall that performs thermal insulation for the door. The thickness of the door along the length of the front-to-back direction Y can provide thermal insulation. The energy nose 39 can provide thermal insulation. The thickness of the door including the energy nose can be referred to as the main thermal insulation region D. The main thermal insulation region can be referred to as the thermal insulation interval. The main thermal insulation region can include an insulation wall region d1 and an energy nose region d2. The insulation wall region can reduce conductive heat. The energy nose region can reduce convective heat through flow. The energy nose region can be the same as the front-to-back length d2 of the embankment. The push rod 6 can be placed in the main thermal insulation region. At least a portion of the push rod can be placed in the energy nose region. At least a portion of the pressurizing part can be placed in the main thermal insulation region. The pressurizing part can be entirely placed in the main thermal insulation region. This improves thermal insulation performance. The sealing gasket can be placed in the main thermal insulation region.

[0191] Figure 11This diagram illustrates the structure used to prevent condensation on doors caused by cold air.

[0192] Reference Figure 11 On the door, the condensation point can be the lowest-temperature area on the outer surface of the door that is in contact with outside air. There can be at least one such lowest-temperature area (c). The lowest-temperature area (c) can be adjacent to the junction of the cap 8 and the internal support plate 22. In the opening module, the lowest-temperature area (c) can be the junction of the lower wall 81 and the rear wall 82. In the opening module, the lowest-temperature area (c) can be 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 towards the lower wall 81 and the rear wall 82. A heat diffusion member 37 can be provided near the lowest-temperature area (c). The heat diffusion member can be a heat diffusion plate. The heat diffusion plate can promote heat transfer. The heat diffusion member can use a thermally conductive metal sheet. The heat diffusion plate can also diffuse cold air. By diffusing the cold air, the temperature of the lowest-temperature area 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 area (c). The heat diffusion plate may be provided on the bottom surface of the lower wall 81 adjacent to the lowest temperature portion c. The heat diffusion plate may be provided on at least one side of the back and front of the inner support plate 22 at a position adjacent to the lowest temperature portion c.

[0193] When the door is thin, condensation at the lowest temperature location can be very severe. The heat diffuser plate prevents condensation. The accompanying drawings illustrate, as an example, the heat diffuser plate 37 being installed on the outer support plate 21, lower support plate 23, inner support plate 22, rear wall 82, and top wall 83. This allows external heat to be transferred to the lowest temperature location c. The arrows indicate the direction of heat transfer. The heat transfer path via the outer support plate 21, lower support plate 23, and inner support plate 22 allows heat to be conducted from the outside air. The heat transfer path via the rear wall 82 and top wall 83 allows heat to be conducted from the heater. Here, the heater can be installed in 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 installed in the partition wall dividing the storage space. Here, the partition wall can be a partition wall dividing the refrigerator compartment and the freezer compartment.

[0194] Figure 12 This is a diagram showing the thickness of the door in the comparative embodiment and the door in the comparative example. Figure 12 (a) is a comparative example where the left and right lengths of the cap groove are relatively long and it has a single push rod. Figure 12 (b) is an embodiment with a shorter left and right length of the cap groove and at least two push rods.

[0195] Reference Figure 12 In the embodiment, the length b1 of the front-to-back Y direction of the door end is less than the length a1 of the front-to-back Y direction of the door end in the comparative example. This allows for a larger internal volume of the storage space. The problem of thinner insulation thickness at the door end can be eliminated through the various solutions described above. In the embodiment, the length b2 of the left-to-right X direction of the cap groove is less than the length a2 of the front-to-back Y direction of the door in the comparative example. This shortens the area where the insulation thickness is narrower.

[0196] The comparative example has a single push rod, which may result in initial door opening difficulties. The force concentrated in one place may be insufficient for initial door opening. Due to the large force applied to a single component, the dimensions of each component become larger. The embodiment can provide at least two push rods. The embodiment can provide two push rods 6 on the left and right sides. The push rods can be symmetrical in the left-right direction X. The push rods can be located near the dividing points when the door is divided into three equal parts in the left-right direction X. The push rods can be located in the middle region when the door is divided into three equal parts in the left-right direction X. The push rods can be located near the second and fourth dividing points starting from one end when the door is divided into six equal parts in the left-right direction X. The attached figures show the case where the push rod is located near the second dividing point starting from the left. The push rods can be located in the third and fourth regions starting from either 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 with minimal external force. Therefore, the force applied to each component can be reduced. Thus, each component can be formed thin and long. This allows for a smaller opening module.

[0197] Figure 13 It is a diagram comparing the internal regions. Figure 13 (a) is a diagram showing the internal region of the comparative example. Figure 13 (b) is a diagram illustrating the internal region of an embodiment. The internal region may be represented by a rectangle.

[0198] Reference Figure 13 In the comparative example's internal region, the ratio W1 / H1 of the vertical Z-direction dimension H1 and the horizontal Y-direction dimension W1 is greater than 1. In the embodiment's internal region, the ratio W1 / H1 of the vertical Z-direction dimension H2 and the horizontal Y-direction dimension W2 is greater than 1. In the embodiment's internal region, the ratio W1 / H1 of the vertical Z-direction dimension H2 and the horizontal Y-direction dimension W2 can be greater than 2. Based on these ratios, it can be determined that the door thickness is reduced. When the door thickness is reduced, a larger storage space can be obtained. This can improve the user's aesthetic experience.

[0199] Figures 14 to 2Figure 0 illustrates a refrigerator door 200 and an opening module 9 according to another embodiment of the present invention. Unless otherwise specified, refer to... Figures 1 to 13 The description of one embodiment can be found directly in Figures 14 to 2 The embodiment shown in Figure 0 uses [the specific feature]. Hereinafter, descriptions of features identical to those in the foregoing embodiments will be omitted. Referring to [the specific example]... Figures 14 to 2 0, indicating another embodiment of the refrigerator of the present invention.

[0200] For example, the structure of the handle 94 in this embodiment differs from the structure of the handle 4 in the aforementioned embodiment. Although the structure of the handle 4 in the aforementioned embodiment cannot be directly applied to this embodiment, its function can be applied. For example, the descriptions of the housing 11 and the first doors 12 and 13 in the aforementioned embodiments can be directly applied to this embodiment.

[0201] Figure 14 This is the front view of door 200. Figure 15 This is the rear view of door 200.

[0202] Reference Figure 14 The door 200 may include a front panel 310. The front panel 310 may face forward. The front panel 310 may include an opening 209.

[0215] Reference Figure 16 The opening module 9 may include a handle 94.

[0216] The handle 94 may include an operating part 95, a rotating shaft 942 that provides a rotation center for the handle, and a lever 943 located below the rotation center.

[0217] The operating unit 95 may include a front side 951 and a rear side 952. The operating unit 95 may include a gripping part 950 (see reference). Figure 17 The grip portion 950 may be located behind the front surface 951. The grip portion 950 may be located between the front surface 951 and the rear surface 952. The grip portion 950 may be recessed upward.

[0218] The handle 94 may include a body 941. The rotation shaft 942 may protrude from the body 942 in a left-right direction.

[0219] Alternatively, a groove may be formed in the body 942, and a shaft may protrude from the housing or door, the shaft being inserted into the groove to provide a rotating shaft for the handle.

[0220] The main body 942 can extend in the width direction of the door 200. In the width direction of the door 200, the main body 942 can extend longer than the operating part 95.

[0221] The handle 94 may include a neck 945. The neck 945 may extend from the body 941. The neck 945 may extend from the center of the body 941. The neck 945 may extend upward from the body 941.

[0222] The neck 945 can be connected to the operating part 95. The neck 945 can be connected to the rear part 952.

[0223] Lever 943 can extend from body 941. Lever 943 can extend downward from body 941.

[0224] The lever 943 may include a first side end and a second side end 944 protruding downwards from the left and right ends of the body 941. The lever 943 may extend in a left-right direction between the first side end and the second side end 944. Alternatively, with... Figure 16 Unlike the example shown, it may also protrude only at the side end of the main body 941.

[0225] In the radial direction, the outer end of the operating part 95 can be located further outward than the outer ends of the levers 943 and 944.

[0226] The opening module 9 may include a linkage 97. The linkage 97 may connect a handle 94 and a push rod 96. The linkage 97 may contact the handle 94.

[0227] Link 97 can be configured to rotate. Link 94 may include a rotation axis 971. The rotation axis 971 of link 97 may be located lower than the rotation center 942 of handle 94.

[0228] Link 97 may include a first arm 972 and a second arm 973. The first arm 972 may extend upward from the rotation axis, and the second arm 973 may extend downward from the rotation axis.

[0229] The first arm 972 can be connected to levers 943 and 944. The first arm 972 can contact levers 943 and 944. The second arm 973 can be connected to the push rod 96. The second arm 973 can contact the push rod 96.

[0230] The first arm 972 may be shorter than the lever 943 or the side end 944 of the lever. The second arm 973 may be longer than the first arm 972.

[0231] Link 97 may include a first link and a second link 97 at the first end and the second end 944 of lever 943.

[0232] The opening module 9 may include a push rod 96. The push rod 96 may be configured to slide in the forward and backward direction. The push rod 96 moves backward by rotation of the handle 94 and the connecting rod 97, and moves forward by elastic member 964. Here, the movement of the push rod 96 may be a relative concept with respect to the door 200.

[0233] Since the second door 200 includes a basket and stores food in the basket, it has a heavy load and its center of gravity is located lower than the handle. In the refrigerator of this embodiment, the point of action of the opening module 9 pushing the cabinet 11 is moved to a lower position than the operating part 95 where the user applies force, thereby preventing the door from rotating and converting the force into translational motion, thus having the advantage of being able to open easily with little force.

[0234] The push rod 960 can be located lower than the operating part 95. The push rod 960 can be positioned at the same height as the lower end of the second arm 973 of the connecting rod 97. The push rod 960 can be positioned adjacent to the side end of the door 200. The push rod 960 is positioned lower than the upper end of the door 200, so that it can contact the side end of the housing 11. The width of the push rod 960 in the left-right direction can be less than its height in the up-down direction.

[0235] The push rod 960 may include an outer end 961 connected to the connecting rod 94, an inner end 963 located at the rear, and an extension 962 connecting the outer end 961 and the inner end 963.

[0236] The outer end 961 can extend from the extension 962 along the width direction of the door and includes a groove 965 and an elastic member 964 (see reference). Figure 17 It is configured in the setting slot 965.

[0237] Although Figure 16 Not shown, but as mentioned above, the opening module 9 may include a housing.

[0238] Figure 17 and Figure 18 (a) is a diagram showing the opening of a refrigerator according to another embodiment of the present invention.

[0239] Reference Figure 17 Door 200 can seal the storage space of cabinet 11. A sealing gasket 111 can be installed on door 200 to seal the space between door 200 and cabinet 11.

[0240] As mentioned above, in reference Figures 1 to 14 In the illustrated embodiment, opening door 200 may require a relatively large force in the initial stage. The user can initially open door 200 by operating opening module 9.

[0241] The user can open the door 200 by pushing the operating unit 95 backward.

[0242] If a force F1 is applied to the operating part 95 in the first direction D1 (rearward), the handle 94 can rotate in the first rotation direction R1 with the rotation axis 942 as the center. At this time, the operating part 95 can move backward, while the levers 943 and 944 move forward.

[0243] exist Figure 17 The diagram shows that the first rotation direction R1 is counterclockwise.

[0244] If handle 94 is rotated in the first rotation direction R1, then connecting rod 972 rotates in the second rotation direction R2, which is opposite to the first rotation direction R1. Connecting rod 972 rotates around rotation axis 971.

[0245] If handle 94 is rotated in the first rotation direction R1, levers 943 and 944 push the first arm 972 forward, and connecting rod 97 rotates in the second rotation direction. If connecting rod 97 rotates in the second rotation direction, the second arm 973 pushes the push rod 96 backward.

[0246] If the linkage 97 pushes the push rod 96 backward, the push rod 96 pushes the housing 11 backward. Since the housing 11 is fixed, the linkage 97, handle 94, and door 200 are pushed forward. That is, the push rod 96 can be in a state of sliding backward relative to the door 200 while remaining relatively stationary relative to the housing.

[0247] With the door 200 blocking the storage space and no external force applied to the handle 94, the push rod 96 can be in contact with the box 11.

[0248] Alternatively, with the door 200 blocking the storage space and no external force applied to the handle 94, the push rod 96 is separated from the housing 11. When an external force is applied to the operating part 95, the push rod 96 can move backward and come into contact with the housing 11. If an external force is applied to the operating part 95 in this state, the handle 94 will rotate further, and the push rod 96 will push the housing 11, thereby leading out the door 200.

[0249] If the user pushes the operating part 95 in the first direction D1, the handle 94 rotates in the first rotation direction 94, the connecting rod 97 rotates in the second rotation direction, the push rod 97 applies pressure to the housing in the first direction, a gap G is created between the housing 11 and the door 200, and the door 200 extends in the second direction D2, becoming... Figure 18 The state.

[0250] On the other hand, the user can also open the door 200 by lifting the operating part 95 upwards. The lower end of the front surface 951 of the operating part 95 can be located further forward than the rotation center 942 of the handle 94. That is, when no external force is applied to the operating part 95, the handle 94 can be rotated so that the lower end of the front surface 951 moves upwards along an arc.

[0251] If the user lifts the operating part 95 upwards, the handle 94 rotates in the first rotation direction 94, the connecting rod 97 rotates in the second rotation direction, and the push rod 97 applies pressure to the housing in the first direction, thereby creating a gap G between the housing 11 and the door 200. The door 200 extends in the second direction D2 and becomes... Figure 18 The state.

[0252] Reference Figure 18 In (a), the elastic member 964 can apply a force F2 forward to the push rod 964. If the external force applied to the operating part 95 is removed, the push rod 96 can move forward due to the elastic member 964, the connecting rod 97 rotates in the first rotation direction, and the handle can rotate in the second rotation direction. The operating part 95 can move forward D2. At this time, the opening module 9 becomes connected with... Figure 17 In the same state shown, door 200 can be spaced forward relative to housing 11. Figure 18 The state of (a).

[0253] When door 200 is initially open, i.e., when door 200 is separated from the housing 11 by G to the front, the user can pull door 200 forward by pulling handle 94 forward by D2 (F3). Of course, the user can also grab other parts of door 200 (such as the top surface of the door) to pull door 200 forward instead of handle 94.

[0254] Reference Figure 17 and Figure 18(a) The user can initially open the door 200 by pushing the (F1) operating part 95 backward D1 while the door 200 is closed, and then pull the (F3) operating part 95 forward D2 or the handle 94 to bring the door 200 out.

[0255] Alternatively, the user can initially open the door 200 by lifting the operating part 95 upwards while the door 200 is closed, and then pull the operating part 95 or the handle 94 forward by pulling forward D2 (F3) to bring the door 200 out.

[0256] For reference Figures 1 to 13 The illustrated embodiment has the advantage that, when the initial opening and subsequent extension of the door 20 are performed in the same direction, the user can extend the door 20 with a single action.

[0257] The force required to initially open doors 20 and 200 differs from the force required for subsequent opening (or extension), especially the initial stage which requires a larger force. Given that the initial and subsequent forces for opening door 200 act in the same direction, the door may be opened rapidly after the initial moment when a large force is required.

[0258] As in this embodiment, if the initial opening of the door 200 and the subsequent extension are in different directions, the user can extend the door 200 by means of two distinct phases of action.

[0259] Therefore, in this embodiment, in order to initially open the door 200 and subsequently extend it, the user can apply force in different directions respectively, which can prevent the door 200 from being opened too quickly.

[0260] In particular, the ability to initially open the door 200 by pushing the handle 94 may be advantageous for users with limited strength, such as children or the elderly.

[0261] Figure 18 This is a diagram showing three embodiments of the relative positions of the handle 94 and the link 97 in the front-rear direction.

[0262] Reference Figure 18 (a) The rotation axis 942 of the handle 94 can be located at a position G1 further forward than the linkage rotation axis 971 of the linkage 97.

[0263] The length of the handle 94 (the length of the handle over its rotation radius) can be greater than the length of the link 97 (the length of the link over its rotation radius). Furthermore, the front surface 951 of the operating part 95 is positioned at or adjacent to the opening 209.

[0264] That is, if the shaft of handle 94 is positioned at the rear, the opening module 9 occupies a large space in the front-to-back direction.

[0265] By positioning the rotation axis 942 of the handle 94 further forward than the rotation axis 971 of the link 97, the space required for setting up the opening module 9 can be reduced, and the door 200 can be designed to be thinner.

[0266] Reference Figure 18 (b) The rotation center 942 of the handle 94 can be located on the same vertical line as the rotation axis 971 of the connecting rod 97. That is, the rotation center 942 of the handle 94 can be located on the vertical upper side of the rotation axis 971 of the connecting rod 97.

[0267] The displacement of levers 943 and 944 relative to handle 94 in the forward and backward direction of their rotation angle is the sine of the angle between the levers and the horizontal direction. Therefore, the change in displacement is the cosine. Thus, the change in displacement is greatest when levers 943 and 944 are located vertically below the rotation axis 942.

[0268] Similarly, the change in displacement of the first arm 971 relative to the front-rear direction is greatest when the first arm is located on the vertical upper side of the rotation axis 971 of the connecting rod 97.

[0269] By arranging the rotation axis 942 of the handle 94 and the rotation axis 971 of the connecting rod 97 on the same vertical line, even if the handle 94 is rotated by a small angle, the push rod 96 can move a lot.

[0270] Reference Figure 18 (c) The rotation axis 942 (or rotation center) of the handle can be located G2 further back than the rotation axis 971 of the link 97.

[0271] As mentioned above, the user can lift the operating part 95 upwards to rotate the handle 94 in the first direction and open the door 200. The torque that rotates the handle 94 in the force required to lift the operating part 95 upwards is equivalent to the cosine of the angle between the horizontal line and the operating part 95. Therefore, the smaller the angle between the horizontal line and the operating part 95, the smaller the force required to open the door 200.

[0272] Since the operating part 95 is located in or adjacent to the opening 209, the further back the rotation axis 942 of the handle 94 is located, the smaller the angle between the horizontal line and the operating part 95 can be.

[0273] Therefore, according to the embodiment of FIG20, it is advantageous for the user to initially open the door 200 by lifting the operating part 95 upward.

[0274] On the other hand, as mentioned above, the opening module 9 may include a housing. The handle 94 is larger in volume than the link 97, and the rotation axis 942 of the handle 94 is located further rearward than the rotation axis 971 of the link 97, thereby creating a space between the housing and the front panel 310. Therefore, when thermal insulation material is filled inside the door 200, the thermal insulation material can be smoothly filled between the housing and the front panel 310.

[0275] The front portion of the housing can be separated from the front panel 310 and rearward. The lower side of the front portion of the housing can be separated from the front panel 310 and rearward.

[0276] The foregoing embodiments or other embodiments of the present invention are not exclusive or distinct from each other. Various constituent elements or functions of the foregoing embodiments or other embodiments of the present invention can be used together or combined.

[0277] For example, this means that configuration A illustrated in a particular embodiment and / or drawing can be combined with configuration B illustrated in other embodiments and / or drawings. That is, even if the combination between structures is not directly described, it is implied that they can be combined unless explicitly stated that they cannot be combined.

[0278] The detailed description described above should not be construed as restrictive in all respects, but rather as exemplary. The scope of the invention should be determined by a reasonable interpretation of the appended claims, and all modifications within the equivalent scope of the invention should fall within its scope.
