[0046] An example in which a heat transfer resistor is connected to and provided on the plate can be understood by replacing the support with the heat transfer resistor in an example in which the support is provided to support the plate. Redundant descriptions are omitted.

As yet another example, the above-mentioned thermal transfer resistor may include a portion having a smaller radius of curvature than the plate.

[0048] Referring to FIG. 4a, for example, a conductive resistance sheet may be provided on a side plate connecting the first plate and the second plate. Referring to FIG. 4b, for example, a conductive resistance sheet (60) may be provided on at least a portion of the first plate and the second plate. A connecting frame (70) may be further provided on the outside of the conductive resistance sheet. The connecting frame may be an extended portion of the first plate or the second plate, or an extended portion of the side plate. Optionally, the connecting frame (70) may include a portion to which components disposed on the outside of the vacuum space are connected, such as a component for sealing between the door and the main body, an exhaust port required for the exhaust process, and a getter port for maintaining a vacuum. Referring to FIG. 4c, for example, a conductive resistance sheet may be provided on a side plate connecting the first plate and the second plate. The conductive resistance sheet may be installed in a through hole penetrating the vacuum space. The conduit (64) may be separately provided on the outer side of the conductive resistance sheet.

[0049] FIG. 5 is a graph observing the process of evacuating the interior of a vacuum insulation body with respect to time and pressure when a support is used. An example of the vacuum evacuation step of the vacuum insulation body is as follows. The present invention may be any one of the following examples or an example in which two or more are combined.

[0050] While the above exhaust step is being performed, an outgassing step may be performed, which is a process in which gas in the vacuum space is exhausted or potential gas remaining in the components of the vacuum insulation is exhausted. As an example of the outgassing step, the exhaust step may include at least one of the steps of heating or drying the vacuum insulation, applying vacuum pressure to the vacuum insulation, and providing a getter to the vacuum insulation. In this case, the potential gas remaining in the components provided in the vacuum space may be vaporized and exhausted. The exhaust step may include a step of cooling the vacuum insulation. The cooling step may be performed after the step of heating or drying the vacuum insulation is performed. Preferably, the step of heating or drying the vacuum insulation and the step of applying vacuum pressure to the vacuum insulation may be performed together. Preferably, the step of heating or drying the vacuum insulation and the step of providing a getter to the vacuum insulation may be performed together. Preferably, after the step of heating or drying the vacuum insulation is performed, the step of cooling the vacuum insulation may be performed. Preferably, the step of providing vacuum pressure to the vacuum insulation and the step of providing a getter to the vacuum insulation may be performed so as not to overlap. For example, the step of providing a getter to the vacuum insulation may be performed after the step of providing vacuum pressure to the vacuum insulation is performed. When vacuum pressure is provided to the vacuum insulation, the pressure in the vacuum space may drop to a certain level and then stop dropping further. At this time, the step of providing vacuum pressure to the vacuum insulation may be stopped, and the getter may be introduced. An example of stopping the step of providing vacuum pressure to the vacuum insulation may be the cessation of the operation of the vacuum pump connected to the vacuum space. When introducing the getter, the step of heating or drying the vacuum insulation may be performed simultaneously. Through this, outgassing can be promoted.As another example, after the step of providing a getter to the vacuum insulation is performed, the step of providing vacuum pressure to the vacuum insulation may be performed.

[0051] The time during which the vacuum evacuation step of the vacuum insulation body is performed may be referred to as the vacuum evacuation time. The vacuum evacuation time may include at least one of the time during which the step of heating or drying the vacuum insulation body is performed (△t1), the time during which the step of maintaining the vacuum insulation body with a getter inserted is performed (△t2), and the time during which the step of cooling the vacuum insulation body is performed (△t3). Examples for △t1, △t2, and △t3 are as follows. Any of the following examples of the present invention may be an example in which two or more are combined. In the vacuum evacuation step of the vacuum insulation body, △t1 may be greater than or equal to t1a and less than or equal to t1b. As a first example, t1a may be greater than or equal to 0.2hr and less than or equal to 0.5hr. t1b may be greater than or equal to 1hr and less than or equal to 24.0hr. Preferably, the above △t1 may be 0.3 hr or more and 12.0 hr or less. Preferably, the above △t1 may be 0.4 hr or more and 8.0 hr or less. More preferably, the above △t1 may be 0.5 hr or more and 4.0 hr or less. In this case, it may be applied to a vacuum insulation body in which outgassing is sufficient even if △t1 is kept as short as possible. For example, among the components of the vacuum insulation body, the component exposed to the vacuum space may include a part having a lower outgassing rate (%) than any one of the components of the vacuum insulation body exposed to the external space of the vacuum space. Specifically, the component exposed to the vacuum space may include a part having a lower outgassing rate than the thermoplastic polymer. More specifically, a support or a radiation-resistant sheet may be placed in the vacuum space, and the outgassing rate of the support may be lower than that of the thermoplastic polymer.As another example, among the components of the vacuum insulator, the component exposed to the vacuum space may include a part having a higher maximum operating temperature (°C) than any of the components of the vacuum insulator exposed to the external space of the vacuum space. In this case, the vacuum insulator can be heated to a higher temperature, thereby increasing the outgassing rate. For example, the component exposed to the vacuum space may include a part having a higher operating temperature than the thermoplastic polymer. As a more specific example, a support or a radiation-resistant sheet may be placed in the vacuum space, and the operating temperature of the support may be higher than that of the thermoplastic polymer. As yet another example, among the components of the vacuum insulator, the component exposed to the vacuum space may include a greater amount of metallic material than non-metallic material. That is, the mass of the metallic material may be greater than the mass of the non-metallic material, the volume of the metallic material may be greater than the volume of the non-metallic material, or the area of ​​the metallic material exposed to the vacuum space The non-metallic material portion may be larger than the area exposed to the vacuum space. If there are multiple parts exposed to the vacuum space, the sum of the volume of the metal material contained in the first part and the volume of the metal material contained in the second part may be greater than the sum of the volume of the non-metallic material contained in the first part and the volume of the non-metallic material contained in the second part. If there are multiple parts exposed to the vacuum space, the sum of the mass of the metal material contained in the first part and the mass of the metal material contained in the second part may be greater than the sum of the mass of the non-metallic material contained in the first part and the mass of the non-metallic material contained in the second part.In the case where there are multiple parts exposed to the vacuum space, the sum of the area of ​​the metal material included in the first part exposed to the vacuum space and the area of ​​the metal material included in the second part exposed to the vacuum space may be greater than the sum of the area of ​​the non-metal material included in the first part exposed to the vacuum space and the area of ​​the non-metal material included in the second part exposed to the vacuum space. As a second example, t1a may be a value greater than or equal to 0.5hr and less than or equal to 1hr. t1b may be greater than or equal to 24.0hr and less than or equal to 65hr. Preferably, △t1 may be 1.0hr or more and 48.0hr or less. Preferably, △t1 may be 2hr or more and 24.0hr or less. More preferably, △t1 may be 3hr or more and 12.0hr or less. In this case, it may be a vacuum insulator that needs to maintain △t1 as long as possible. Examples of this case may include the opposite of the examples described in the first example above, or cases where the part exposed to the vacuum space is a thermoplastic material. Redundant descriptions are omitted. In the vacuum evacuation step of the vacuum insulator, △t2 may be greater than or equal to t2a and less than or equal to t2b. t2a may be greater than or equal to 0.1hr and less than or equal to 0.3hr. t2b may be greater than or equal to 1hr and less than or equal to 5.0hr. Preferably, △t2 may be greater than or equal to 0.2hr and less than or equal to 3.0hr. More preferably, △t2 may be greater than or equal to 0.3hr and less than or equal to 2.0hr. More preferably, △t2 may be greater than or equal to 0.5hr and less than or equal to 1.5hr. In this case, the vacuum insulation may be sufficient for outgassing through a getter even if △t2 is kept as short as possible. In the vacuum evacuation step of the vacuum insulation, △t3 may be greater than or equal to t3a and less than or equal to t3b. t3a may be greater than or equal to 0.2hr and less than or equal to 0.8hr. t3b may be greater than or equal to 1hr and less than or equal to 65.0hr.Preferably, the above △t3 may be 0.2 hr or more and 48.0 hr or less. Preferably, the above △t3 may be 0.3 hr or more and 24.0 hr or less. More preferably, the above △t3 may be 0.4 hr or more and 12.0 hr or less. More preferably, the above △t3 may be 0.5 hr or more and 5.0 hr or less. After the heating or drying step is performed during the above exhaust step, the above cooling step may be performed. For example, if the time during which the heating or drying step is performed is long, △t3 may be extended. The vacuum insulation body of the present invention may be manufactured such that △t1 is greater than △t2, or such that △t1 is less than or equal to △t3, or such that △t3 is greater than △t2. Preferably, △t2 < △t1 ≤ △t3. The vacuum insulation of the present invention may be manufactured such that △t1+△t2+△t3 is greater than or equal to 0.3 hr and less than or equal to 70 hr, greater than or equal to 1 hr and less than or equal to 65 hr, greater than or equal to 2 hr and less than or equal to 24 hr. More preferably, △t1+△t2+△t3 may be manufactured such that it is greater than or equal to 3 hr and less than or equal to 6 hr.

[0052] Examples of vacuum pressure conditions during the above exhaust step are as follows. The present invention may be any one of the following examples or an example in which two or more are combined. During the above exhaust step, the minimum vacuum pressure of the vacuum space may be greater than 1.8E-6 Torr. Preferably, the minimum vacuum pressure may be greater than 1.8E-6 Torr and less than or equal to 1.0E-4 Torr, greater than 0.5E-6 Torr and less than or equal to 1.0E-4 Torr, greater than 0.5E-6 Torr and less than or equal to 0.5E-5 Torr. More preferably, the minimum vacuum pressure may be greater than 0.5E-6 Torr and less than 1.0E-5 Torr. Limiting the minimum vacuum pressure provided during the above exhaust step in this way is because, even if pressure reduction is performed by a vacuum pump during the above exhaust step, the rate at which the vacuum pressure decreases slows down below a certain level. As an example, after the exhaust step is performed, the vacuum pressure of the vacuum space may be maintained at a pressure greater than or equal to 1.0E-5 Torr and less than or equal to 5.0E-1 Torr. The maintained vacuum pressure may be greater than or equal to 1.0E-5 Torr, less than or equal to 1.0E-1 Torr, greater than or equal to 1.0E-5 Torr, less than or equal to 1.0E-2 Torr, greater than or equal to 1.0E-4 Torr, less than or equal to 1.0E-2 Torr, greater than or equal to 1.0E-5 Torr, less than or equal to 1.0E-3 Torr, greater than or equal to 1.0E-4 Torr, and less than or equal to 1.0E-3 Torr. As a result of predicting the change in vacuum pressure through accelerated testing of two example products, it was confirmed that one vacuum pressure was maintained at 1.0E-04 Torr or lower even after 16.3 years, and the other vacuum pressure was maintained at 1.0E-04 Torr or lower even after 17.8 years.As such, the vacuum pressure of the vacuum insulation must be maintained below a predetermined level, even with aging changes, in order to be utilized in a desirable industrial manner.

[0053] Figure 5a is a graph of the elapsed time and pressure of an exhaust process according to one example, and Figure 5b explains the results of a long-term vacuum maintenance experiment conducted as an accelerated test on a vacuum insulation of a refrigerator with an internal volume of 128 liters. Referring to Figure 5b, it can be seen that the vacuum pressure gradually increases with age. For example, it was confirmed that it reached 6.7E-04 Torr after 4.7 years, 1.7E-03 Torr after 10 years, and 1.0E-02 Torr after 59 years. Based on these experimental results, it can be confirmed that the vacuum insulation according to the example is sufficiently suitable for industrial application.

[0054] FIG. 6 is a graph comparing vacuum pressure and gas conductivity. Referring to FIG. 6, the gas conductivity according to vacuum pressure is shown as a graph of the actual heat transfer coefficient (eK) according to the size of the gap inside the vacuum space (50). The gap of the vacuum space was measured in three cases: 3 mm, 4.5 mm, and 9 mm. The gap of the vacuum space is defined as follows: when the radiation resistance sheet (32) is inside the vacuum space, it is the distance between the radiation resistance sheet and the adjacent plate, and when the radiation resistance sheet is not inside the vacuum space, it is the distance between the first plate and the second plate. It was observed that the point corresponding to the actual heat transfer coefficient of 0.0196 W / mk, which is provided by foaming polyurethane as an insulating material, is 5.0E-1 Torr even when the gap size is small at 3 mm. Meanwhile, it was confirmed that even if the vacuum pressure decreases, the point at which the reduction effect of the insulation effect due to gas conduction heat becomes saturated is approximately 4.5E-3 Torr. The pressure of 4.5E-3 Torr can be determined as the point at which the reduction effect of gas conduction heat becomes saturated. In addition, when the actual heat transfer coefficient is 0.01 W / mk, it is 1.2E-2 Torr. An example presenting the range of vacuum pressure in the vacuum space according to the gap is as follows. When the support includes at least one of a bar, a connecting plate, and a support plate, and the gap in the vacuum space is greater than or equal to 3 mm, the vacuum pressure may be greater than or equal to A and less than 5E-1 Torr, or greater than 2.65E-1 Torr and less than 5E-1 Torr. As another example, the support comprises at least one of a bar, a connecting plate, and a support plate, and when the gap of the vacuum space is greater than or equal to 4.5 mm, the vacuum pressure may be greater than or equal to A and less than 3E-1 Torr, greater than 1.2E-2 Torr, and less than 5E-1 Torr.As another example, the support comprises at least one of a bar, a connecting plate, and a support plate, and when the gap of the vacuum space is greater than or equal to 9 mm, the vacuum pressure may be greater than or equal to A and less than 1.0 × 10^-1 Torr, greater than 4.5 E-3 Torr, and less than 5 E-1 Torr, where A may be greater than or equal to 1.0 × 10^-6 Torr and less than or equal to 1.0 E-5 Torr. Preferably, A may be greater than or equal to 1.0 × 10^-5 Torr and less than or equal to 1.0 E-4 Torr. When the support comprises a porous material or a filler, the vacuum pressure may be greater than or equal to 4.7 E-2 Torr and less than or equal to 5 E-1 Torr. In this case, the size of the gap can be understood to be from several micrometers to several hundred micrometers. When the support and the porous material are provided together in the vacuum space, a vacuum pressure intermediate between the case where only the support is used and the case where only the porous material is used can be created and used.

[0067] As an example, examples of processes related to the support are as follows. The present invention may be any one of the following examples or an example combining two or more of them. The vacuum insulation component preparation step may include a step of manufacturing the support. The step of manufacturing the support may be performed before the vacuum insulation vacuum evacuation step is performed. For example, the support may be manufactured by injection molding. Optionally, a step of cleaning the support may be performed before the vacuum insulation vacuum evacuation step is performed. A step of storing the support under predetermined conditions may be performed before or during the vacuum insulation vacuum evacuation step is performed. For example, the first storage step may be performed before the vacuum insulation vacuum evacuation step is performed, and the second storage step may be performed during the vacuum insulation vacuum evacuation step. As another example, the storage step may be performed during the vacuum insulation vacuum evacuation step. Examples of the storage step are as follows.

For example, the joining step may include a step of joining the bar of the support and a connecting plate. As another example, the joining step may include a step of joining the bar of the support and a support plate.

[0069] Regarding the support, the process may optionally include a process related to the step of storing the support under predetermined conditions.

The step of drying or heating the support and the step of storing the support at atmospheric pressure may be performed simultaneously. The step of storing the support under conditions lower than atmospheric pressure and the step of cooling the support can be performed simultaneously.

[0070] With respect to the above support, the process may optionally include a process related to the step of joining the support. An example of a process sequence related to the step of joining the support is as follows. The present invention may be any one of the following examples or an example in which two or more are combined. Before the joining step is performed, a step of providing a separate part separated from the support in a space provided inside the support may be performed. For example, the part may include a heat transfer resistor. After the joining step is performed, a step of packaging or storing the support in a vacuum state may be performed. After the step of storing the support under predetermined conditions is performed, a step of joining a plurality of parts of the support together may be performed.

[0071] Regarding the support, the process may optionally include a process related to the step of cleaning the support. An example of a process sequence related to the step of cleaning the support is as follows. The present invention may be any one of the following examples or an example in which two or more are combined. After the step of manufacturing the support is performed, at least one of the step of cleaning the support, the step of storing the support under a predetermined condition, and the step of joining a plurality of parts of the support together may be performed. After the step of cleaning the support is performed, at least one of the step of storing the support under a predetermined condition and the step of joining a plurality of parts of the support together may be performed. Before the step of cleaning the support is performed, at least one of the step of storing the support under a predetermined condition and the step of joining a plurality of parts of the support together may be performed.

[0072] Regarding the above support, the process may optionally include a process related to the step of providing the support to the plate.

The present invention may be any one of the following examples or an example in which two or more are combined. Before the vacuum insulation vacuum evacuation step is performed, the support may be provided in the space between the first plate and the second plate. Before the vacuum insulation vacuum evacuation step is performed, the support may be provided inside the plate or on the surface of the plate. Before the vacuum insulation vacuum evacuation step is performed, the support may be coupled to the plate. After the component fastening part is provided on a part of the plate, the support may be provided in the space between the first plate and the second plate.

[0073] The contents described in FIGS. 1 to 11 may be applied to all or optionally to the embodiments presented in the following drawings.

[0074] FIG. 12 is a perspective view and a partial cross-sectional view of a vacuum insulation body, FIG. 12(a) is a vacuum insulation body with the left side facing down and the right side facing up, FIG. 12(b) is a cross-sectional perspective view of 1-1' in (a), and FIG. 12(c) is a cross-sectional view of 1-1'. In this drawing, the foam member is shown in a removed state.

[0075] Referring to FIG. 12, the vacuum insulation body can be used in a door that opens and closes the receiving space. A hinge may be installed on the first side of the vacuum insulation body. The first side may be provided thinner than the second side to avoid interference when opening and closing the door. The additional insulation body (90) may be provided thinner on the first side than on the second side. The first side and the second side may be placed facing each other. The first side may point toward A in FIG. 12(a), and the second side may point toward B in FIG. 12(a). The thickness of the sides C and D connecting A and B may gradually change. Here, C may be the upper third side of the vacuum insulation body, and D may be the lower fourth side of the vacuum insulation body.

[0076] The above description of sides may also be applied to the first plate (10), the second plate (20), the side plate (15), the additional insulation (90), and the gasket (80). For example, the first and second plates may be provided in a rectangular shape. For example, the side plate may have four sides in a rectangular shape.

[0077] In one or more embodiments, the tube (40) may be provided where the vacuum space (50) and the additional insulation (90) meet. A first end of the tube (40) may be placed in the vacuum space (50), and a second end of the tube (40) may be placed in the additional insulation (90). The tube (40) may protrude into the additional insulation (90). The other end of the tube (40) may not protrude into the receiving space, thereby preventing waste of the receiving space. The foamed insulation is an insulation material that solidifies after a foaming liquid is injected into the periphery of the vacuum insulation and expands. The foaming liquid may be exemplified by polyurethane. The foamed insulation may generate high pressure during the expansion process. The foamed insulation may allow the foamed insulation to penetrate into the narrow space of the periphery. The above pipe (40) may not extend beyond the outer boundary of the additional insulation (90). The above pipe (40) may be embedded in the additional insulation (90) and the vacuum space (50). An example of the above pipe may be a port, such as an exhaust port or a getter port.

[0078] Optionally, the height of the tube (40) can be secured to be at least twice the diameter of the tube (40). Pinch-off can be performed after exhaust is completed through the tube (40). When pinch-off, compression deformation can be propagated. The propagating deformation can prevent deformation and damage to the connection part between the tube (40) and the plate. The tube (40) can be placed at the corner (211) opposite the upper hinge among the four corner parts (211) of the vacuum insulation body. The tube (40) can be placed on the upper part of the vacuum insulation body to prevent damage to the tube (40). Examples of the tube mentioned above may be ports such as exhaust ports or getter ports.

[0079] Optionally, the foaming liquid may be injected from the top downwards to utilize gravity. The foaming liquid may be filled first at the bottom of the vacuum insulation. When filling the foaming liquid, a phenomenon may occur where the foaming liquid is pushed downwards in the direction of gravity. The expansion force of the foaming liquid is greater at the bottom of the vacuum insulation than at the top. The foaming liquid placed at the bottom of the vacuum insulation has a greater expansion force due to, first, the pressure exerted by the foaming liquid at the top, and second, the constraint on the foaming space caused by the foaming liquid that solidified first at the top. To reduce the effect of the expansion force of the foaming liquid on the tube (40), the tube (40) may be provided at the top of the vacuum insulation. To minimize the effect of the expansion force of the foaming liquid on the tube (40), the tube (40) may be provided at the first part (101) of the first plate on the upper side of the vacuum insulation. When ductile copper is used as the material for the above-mentioned tube (40), the above-mentioned tube (40) may deform directly. An example of the above-mentioned tube may be a port, such as an exhaust port or a getter port.

[0080] Optionally, to reduce the effect of local differences in the expansion force of the foaming liquid on the tube (40), the tube (40) may be provided on the upper part of the vacuum insulation. The tube (40) may be provided on the first part (101) of the first plate on the upper side of the vacuum insulation. The tube (40) may be spaced apart from the side plate (15) of the vacuum insulation by a predetermined distance (W1). Since the foaming liquid solidifies in bundles, the expansion force of the foaming liquid may vary locally. For example, the expansion force of the foaming liquid on the right side of the tube (40) may be greater than the expansion force of the foaming liquid on the left side of the tube (40). In this case, the tube (40) may be damaged. Damage to the tube (40) may include deformation of the connection part between the tube (40) and the first plate (10) and expansion damage to the sealing part of the tube (40). Examples of the aforementioned pipes may be ports such as exhaust ports or getter ports.

[0081] Optionally, the insulation thickness on the side of the vacuum insulation where the hinge is placed may be thinner than on the opposite side. The tube (40) may be placed on the side opposite the hinge of the vacuum insulation to reduce insulation loss. The side opposite the hinge of the vacuum insulation may refer to the side opposite to the side where the hinge is installed. An example of the aforementioned tube may be a port, such as an exhaust port or a getter port.

[0082] Optionally, the tube (40) may have a long portion protruding into the additional insulation (90). The tube (40) may provide a heat conduction path for heat passing through it. The tube (40) provides a position in which it is placed by excluding the foaming agent that makes the additional insulation (90). The tube (40) may cause insulation loss in the vacuum insulation. To reduce insulation loss caused by the tube (40), the tube (40) may be placed on the side opposite the hinge of the vacuum insulation having a relatively thick additional insulation (90). The tube (40) may be provided in the first portion (101) of the first plate on the side opposite the hinge of the vacuum insulation. An example of the aforementioned tube may be a port, such as an exhaust port or a getter port.

[0083] FIG. 13 is a cross-sectional perspective view and a cross-sectional view illustrating the cross section 2-2' of FIG. 12(a), where (a) is a cross-sectional perspective view and (b) is a cross-sectional view.

[0084] Referring to FIG. 13, the foaming liquid is injected through the foaming liquid injection port (470). The foaming liquid injection port (470) may not be aligned vertically with the pipe (40). The pipe (40) may avoid the passage path of the foaming liquid. The foaming liquid injected through the foaming liquid injection port can go down to the bottom of the vacuum insulation body without getting stuck in the pipe (40). Examples of the aforementioned pipe may be ports such as exhaust ports or getter ports.

[0085] Preferably, the distance (W1) between the tube (40) and the side plate (15) is smaller than the distance (W2) between the tube (40) and the upper cover (112). The upper cover (112) may be placed on the edge of the third side. A lower cover (113) may be placed on the fourth side of the vacuum insulation facing the upper cover (112). Examples of the tubes mentioned above may be ports such as exhaust ports or getter ports.

[0086] FIGS. 14 to 16 are drawings related to the cross-section of 3-3' of FIG. 12(a), FIG. 14 is a cross-sectional view of 3-3' of FIG. 12(a), FIG. 15 is an enlarged cross-sectional view of the Z portion of FIG. 14, and FIG. 16 is a cross-sectional perspective view.

[0087] Referring to FIGS. 14 to 16, the thickness of the vacuum insulation on the second side may be thicker than the thickness on the first side. The thickness of the additional insulation (90) on the second side may be thicker than the thickness on the first side. Here, the thickness of the vacuum insulation may refer to the height between the first and second plates (10)(20). The height of the vacuum space (50) on the first side and the second side may be the same.

[0088] Optionally, the distance (W3) from the third part (203) of the second plate on the second side to the tube (40) may be smaller than the distance (W2) between the tube (40) and the upper cover (112). Accordingly, the thermal insulation loss leaking upward from the tube (40) can be further reduced. An imaginary extension line (X-direction) of the second part (152) of the side plate on the second side may pass through the tube (40). According to this, the thermal insulation loss leaking from the tube (40) toward the second side of the vacuum insulation body can be reduced. The third part (203) of the second plate may be placed on the edges of the first side and the second side. An example of the aforementioned tube may be a port, such as an exhaust port or a getter port.

[0089] Optionally, a flange (42) may be provided on the first plate (10) to connect the tube (40) and the first plate (10). The flange (42) may extend inwardly into the vacuum space (50). In this case, it is easy to insert the tube (40) into the flange (42). In this case, the tube (40) can be easily connected to the flange (42) even when the first plate (10) and the second plate (20) are connected.

[0100] FIG. 19 is a drawing comparing the peripheral portions on both sides of a vacuum insulation body according to an embodiment, and is a drawing comparing a cross-sectional view of the second side of the vacuum insulation body with the first side of the vacuum insulation body.

[0101] Referring to FIG. 19, the second side of the vacuum insulation and the first side of the vacuum insulation are different from each other. An additional insulation (90) placed inside, which can be defined as the interior of the first plate (10), the second plate (20), and the side plate (15), is different from the first and second sides. Various insulating materials, such as foamed insulation or pre-molded resin, can be used for the additional insulation (90).

[0102] The insulation area (XY plane) of the additional insulation body (90) may be larger on the second side than on the first side. The insulation thickness of the additional insulation body (90) in the height direction (Y direction) of the vacuum space (50) may be larger on the second side than on the first side. Accordingly, more additional insulation bodies (90) can insulate the second side, and the insulation performance of the second side, such as the latch (81), can be further reinforced. The insulation thickness of the additional insulation body (90) in the length direction (X direction) of the vacuum space (50) may be larger on the first side than on the second side. Accordingly, heat loss leaking to the edge of the second side, which has a smaller insulation area compared to the first side, can be reduced.

[0103] The rate of change in insulation thickness in the height direction (Y direction) of the vacuum space (50) of the additional insulation body (90) may be greater on the first side than on the second side. Accordingly, while reducing insulation loss, interference with parts due to the opening and closing of the door on the side where the hinge is placed can be minimized. Accordingly, the angle of inclination (A) of the second part of the second plate (20) may be greater on the first side. Although the second part (202) of the second plate may cause interference with external objects, interference can be prevented because the angle of inclination (A) of the second part (202) of the second plate is large.

[0104] The additional insulation (90) may use a foamed insulation material. The foamed insulation material may undergo a process of solidification after injecting a foaming liquid. The foaming liquid is a fluid and is affected by the hydraulic diameter of the space into which it is injected. The hydraulic diameter may be proportional to the insulation area and inversely proportional to the length of the curve surrounding the insulation area. The hydraulic diameter may be larger on the second side than on the first side. The foaming liquid may flow more smoothly on the second side than on the first side. The second side may be filled with more foaming liquid than the first side. When a large amount of foaming liquid is injected, a greater foaming pressure may be applied.

[0105] Since the hydraulic diameter on the second side is larger than on the first side, the foaming liquid on the first side cannot flow smoothly. To improve the fluidity of the foaming liquid, the second part (152) of the side plate on the first side does not extend to the component. To improve the fluidity of the foaming liquid, the second part (152) of the side plate on the first side may maintain a predetermined distance from the component in the longitudinal direction (X-direction) of the vacuum space (50). To improve the fluidity of the foaming liquid, the second part (152) of the side plate on the first side may not overlap with the component in the height direction (Y-direction) of the vacuum space (50). Here, the component may include a hinge.

[0106] Although the fluidity of the foaming liquid is not poor on the second side, the position of each member may be misaligned or the member may be deformed due to the high foaming pressure. The second part (152) of the side plate on the second side may extend beyond the member in the longitudinal direction (X direction) of the vacuum space (50). Accordingly, the second part (152) of the side plate and the member may interact to maintain the positional relationship between the members according to the design. The second part (152) of the side plate on the second side may overlap with the member in the height direction (Y direction) of the vacuum space (50). Accordingly, the second part (152) of the side plate and the member may interact to maintain the positional relationship between the members according to the design. Here, the member may include a latch (81). In addition, multiple members may come into contact with each other, support each other, or be fixed to each other. Through this interconnected structure, movable members such as the latch (81) exposed to external impact can maintain their original design position.

[0107] The first side and the second side may have the same component mounted on the additional insulation. The component may include a gasket (80). The gasket (80) may be placed on the same plane. A virtual line perpendicular to the virtual plane formed by the gasket (80) may be provided. A first virtual line (L1) and a second virtual line (L2) may be provided on the first side. A third virtual line (L3) and a fourth virtual line (L4) may be provided on the second side. The spacing between the first and second virtual lines (L1)(L2) may represent the area where the component is placed on the first side. The spacing between the third and fourth virtual lines (L3)(L4) may represent the area where the component is placed on the second side.

[0108] The vacuum space (50) extends further toward the periphery of the vacuum insulation body on the first side than on the second side. The vacuum space (50) on the first side extends further beyond the virtual line than on the second side. Accordingly, the vacuum space (50) on the first side can reinforce the insulation wall of the foam insulation material that is narrow in the height direction. By utilizing the large insulation effect of the vacuum space (50), the insufficient insulation effect of the foam insulation material can be reinforced.

[0109] The edge of the second part (152) of the side plate moves further toward the periphery of the vacuum insulation body on the first side than on the second side. The edge of the second part (152) of the side plate extends the vacuum space (50) on the first side beyond the virtual line and further than on the second side. Accordingly, the second part (152) of the side plate on the first side moves to the extent that it almost touches the hinge axis (21). The first side can reinforce the insulation wall of the foam insulation material where the vacuum space (50) is narrow in the height direction. By utilizing the large insulation effect of the vacuum space (50), the insufficient insulation effect of the foam insulation material can be reinforced. It can further support the load acting on the adjacent area of ​​the hinge axis (21).

[0110] The edge of the heat transfer resistor (32) moves further toward the periphery of the vacuum insulation on the first side than on the second side. The edge of the heat transfer resistor (32) extends the vacuum space (50) on the first side beyond the virtual line and further than on the second side. The first side can reinforce the insulation wall of the foam insulation material, which is narrow in the height direction, with the vacuum space (50) on the first side. By utilizing the large insulation effect of the vacuum space (50), the insufficient insulation effect of the foam insulation material can be reinforced. Radiant heat transfer of the vacuum space (50) can be further reduced on the first side. An example of a heat transfer resistor described in FIG. 19 may be a radiation resistance sheet.

[0111] Among the supports (30), the outermost bar moves further toward the periphery of the vacuum insulation body on the first side than on the second side. The outermost bar extends the vacuum space (50) on the first side beyond the two virtual lines and further than on the second side. With this configuration, the vacuum space (50) can be supported over a long area on the first side.

[0112] The outermost bar among the supports (30) may not be placed in the area formed by the two virtual lines (L1, L2). In other words, the outermost bar may not overlap with the area where the gasket (80) extends in the height direction of the vacuum space (50). The heat conduction distance between the gasket (80) and the outermost bar may be increased. Accordingly, heat loss passing through the gasket (80) and the outermost bar can be reduced. Accordingly, the thermal insulation loss caused by the narrow foam wall on the first side can be compensated.

[0113] FIG. 20 is a drawing comparing a cross-sectional view of the second side of the vacuum insulation body with a cross-sectional view of the first side of the vacuum insulation body, and using this drawing, the configuration related to the latch and hinge is explained in detail.

[0114] A hinge including a hinge shaft (21) may be placed on the first side. A latch (81) may be placed on the second side. At least a portion of the latch may be received in a component receiving space (830). The component receiving space (830) may receive various components exemplifying the latch. An additional insulating body (90) may not be placed in the component receiving space (830). The additional insulating body (90) may not interfere with the operation of the component.

[0115] The above-mentioned component receiving space (830) may be protected by a component case (810) that opens upward with respect to the height direction (y-axis) of the vacuum space. The component case (810) may provide a lower wall of the component receiving space (830). The component case (810) may have a lower portion (811) adjacent to the second portion (152) of the side plate. The component case (810) may have an inner portion (812) adjacent to the center of the vacuum space. The component case (810) may have an outer portion (813) adjacent to the periphery of the vacuum space. The component case (810) may be provided as a single unit. The second portion (102) of the first plate may have a gasket seating portion (103) on which the gasket (80) is placed. The second part (102) of the first plate may have a plurality of folded cross-sections. The second part (102) of the first plate may have fourth and fifth parts (107) (105) of the first plate extending in the height direction of the vacuum space. The fourth part (107) of the first plate may be aligned with the inner part (812). The fourth part (107) of the first plate may be closer to the component receiving space (830) than the inner part (812). The second part (102) of the first plate may have a stepped part (108). The upper end of the inner part (812) may contact the lower end of the stepped part (108). Foaming liquid may not flow between the inner portion (812) and the fourth portion (107) of the first plate. The fifth portion (105) of the first plate may be aligned with the outer portion (813). The fifth portion (105) of the first plate may be closer to the component receiving space (830) than the outer portion (813). The fifth portion (105) of the first plate may have a stepped portion (1051).The upper end of the outer part (813) may come into contact with the lower end of the stepped part (1051). Foaming liquid may not flow between the outer part (813) and the fifth part (105) of the first plate. The second part (102) of the first plate may have a sixth part (106) of the first plate that contacts the second plate (20). The second plate (20) and the sixth part (106) of the first plate may be firmly connected to each other.

[0116] The upper wall of the above-mentioned part receiving space (830) may be provided by a part cover (820). The part cover (820) may have a step. The part cover (820) may have a plate-corresponding surface (822) at the same height as the sixth part (106) of the first plate. The part cover (820) may have a through hole (823). The through hole (823) may be provided in the plate-corresponding surface (822). The part cover (820) may have a gasket seating portion (821) on which the gasket is seated. The gasket seating portion (821) and the plate-corresponding surface (822) may be placed at different heights in the height direction of the vacuum space. At least a part of a latch, for example, a hook, may protrude outward from the through hole (823). The hook may engage with the main body. The above latch (81) may have a portion that extends long in the depth direction (z-axis) of the vacuum space. The extended portion may extend long vertically within the component receiving space (830). The lower end of the latch may reach the lower end of the vacuum insulation body. The upper end of the latch may reach the middle part of the vacuum insulation body. An operating knob may be provided at the lower end of the latch. A locking projection may be provided at the upper end of the latch.

[0117] After the above-mentioned part case (810) and the above-mentioned first plate (10) are connected, the latch (81) can be placed. After the latch (81) is placed, the above-mentioned part cover (820) can be connected. After the above-mentioned part cover (820) is connected, the above-mentioned gasket (80) can be connected.

[0118] FIG. 21 is a drawing describing a hinge shaft cover on which the hinge shaft is placed and a hinge case. FIG. 22 is a drawing showing the state in which a hinge is installed in the hinge case.

[0119] Referring to FIGS. 21 and 22, the hinge may include a hinge shaft cover (22) on which the hinge shaft (21) is placed in order to place the hinge, and a hinge case (23) on which a link (24) is placed that is connected to the hinge shaft cover (22) and connects the hinge body to the main body (2). The hinge shaft cover (22) and the hinge case (23) may be made of resin. The hinge shaft cover (22) may surround the hinge shaft (21). The hinge shaft cover (22) and the hinge case (23) may be provided by being recessed in the depth direction (Z-axis) of the vacuum space (50).

[0120] In the first vacuum insulation body (11), the extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) may not overlap with the range (L1) of the hinge axis (21). Here, overlap may mean penetration. In the first vacuum insulation body (11), the extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) may not overlap with the range (L2 or L3) of the hinge axis cover (22). In the first vacuum insulation body (11), the extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) may overlap with the range (L4) of the hinge case (23). Members extending in the depth direction of the vacuum space (50) may include an inner panel (111), a support (30), a radiation resistance sheet (32), a second plate (20), a first plate (10), and an outer panel (211).

[0121] The extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) does not form an angle of inclination with the extension axis of the hinge axis (21). The extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) may be parallel to the extension axis of the hinge axis (21).

[0122] The lower space of the above hinge shaft cover (22) makes it difficult for the foaming liquid to flow. In order not to obstruct the flow path of the foaming liquid, a member extending in the depth direction (Z-axis) of the above vacuum space (50) can be prevented from encroaching on the lower part of the above hinge shaft cover (22). A supply line, such as a water way or an electric way, can pass through the above hinge shaft (21). The above supply line may interfere with the member extending in the depth direction (Z-axis) of the above vacuum space (50). To avoid such interference, the member extending in the depth direction (Z-axis) of the above vacuum space (50) can be prevented from entering the lower side of the above hinge shaft cover (22).

[0123] The extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) from the first vacuum insulation body (11) may overlap with the hinge case (23). Here, overlap may mean penetration. The extension line of the member extending in the depth direction (Z-axis) of the vacuum space (50) may overlap with the link (24). Due to this overlapping relationship, the first vacuum insulation body (11) can support the hinge case (23). The member extending in the depth direction of the vacuum space (50) may include an inner panel (111), a support (30), a radiation resistance sheet (32), a second plate (20), a first plate (10), and an outer panel (211).

[0124] Since the first vacuum insulation body (11) is made of a metal with a high specific gravity, a greater load is generated on the hinge. If an excessive load is applied to the hinge, deformation may occur. The load applied to the hinge shaft cover (22) and the hinge case (23) can be supported by the first vacuum insulation body (11). Since the load on the hinge causes rotational deformation, it can support both the hinge shaft cover (22) and the hinge case (23).

[0125] Since the first vacuum insulation body (11) supports the hinge case (23), deformation and damage to the hinge can be prevented. To facilitate the support of the hinge case (23), the second part (152) of the side plate can come into contact with the hinge case (23) and the vacuum space (50) in the height direction (Z-axis). The second part (152) of the side plate can support the hinge case (23). The second part (152) of the side plate can come into contact with the hinge shaft cover (22) and the vacuum space (50) in the length direction (X-axis). The second part (152) of the side plate can support the hinge shaft cover (22). Industrial applicability

[0126] According to the present invention, a vacuum insulation material applicable to real life can be provided.
