Problems solved by technology

In addition, gas is introduced from the outside into the vacuum heat insulating material through the outer envelope, so that the degree of vacuum inside the vacuum heat insulating material is lowered and the heat insulating performance of the vacuum heat insulating material is lowered.

[0060] figure 1 A cross-sectional view illustrating a configuration of a refrigerator E according to various embodiments of the present disclosure.

[0061] like figure 1 As shown, the refrigerator E according to the present embodiment includes an outer case 33 and inner cases 32 and 31 received in the outer case 33 and forming storage compartments in the outer case 33 , respectively. Both the inner cases 32 and 31 and the outer case 33 have openings formed in the forward direction. exist figure 1 In the example shown, the storage compartment in the inner shell 32 is a freezer compartment 43 set to be at a freezing temperature, and the storage compartment in the inner shell 31 is a refrigerated compartment 45 set to be at a refrigerated temperature.

[0062] The vacuum heat insulator 1 on the rear surface of the refrigerator E is provided between the inner cases 32 and 31 and the outer case 33, and the vacuum heat insulator 38 on the top surface of the refrigerat...

no. 2 approach

[0116] Figure 5 A cross-sectional view showing a configuration of a vacuum heat insulator according to various embodiments of the present disclosure.

[0117] In the vacuum heat insulating material 1 according to the above embodiment, the container 7 includes the two openings 23A and 23B, but as Figure 5 As shown, only one opening 23 may be formed. Furthermore, the location where the opening 23 is to be formed is not limited to the discharge port 8 of the outer envelope 2 , and the opening 23 may be formed in any surface of the container 7 . Specifically, for example, as Image 6 As shown, the opening 23 is formed in the surface 72 of the container 7, and as Figure 5 As shown, the opening 23 may be installed such that the opening direction of the opening 23 is perpendicular to the suction direction of the evacuation.

[0118] According to this configuration, since only one opening 23 is formed, the operability of processes S2 and S4 can be improved. In addition, because ...

no. 3 approach

[0120] In the first and second embodiments, two openings 23 or one opening 23 are formed, but three or more (ie, plural) openings may be formed. Specifically, for example, a plurality of small openings each having a maximum diameter of about 3 mm may be formed. Therefore, in the process S4, when the container 7 is installed in the outer envelope 2, the adsorbent 9 is not easy to overflow from the inside of the container 7, thereby improving workability.

[0121] Regardless of the embodiment of the opening 23, the ratio of the area of ​​the opening 23 to the total surface area of ​​the outer surface 7B of the container 7 (hereinafter, referred to as "area ratio") is preferably 2 to 40%, more specifically 3 to 40%. 30%, and especially preferably 4 to 20%. Therefore, the ratio of the adsorbent 9A and the adsorbent 9B can be adjusted, thereby improving the short-term and long-term performance of the adsorbent 9 .

[0122] With this configuration, the adsorbent 9B only needs to d...

Abstract

In an insulator including an adsorbent configured to adsorb gas, an initial adsorption performance of the remaining gas inside the insulator using the adsorbent and a long-term adsorption performanceof gas introduced into the insulator from the outside are improved so that the short-term performance and the long-term performance of the insulator can be simultaneously improved. An adsorbent that is a first part of an adsorbent included in a vacuum insulator is accommodated in a first space formed with an inside surface of a container, and an adsorbent that is a second part of the adsorbent isdispersed into a second space formed with an inside surface of an outer envelope and an outside surface of the container.

Description

technical field [0001] Embodiments of the present disclosure relate to a vacuum insulation, a method of manufacturing the vacuum insulation, and a refrigerator having the vacuum insulation. Background technique [0002] Because, recently, the energy saving of refrigerators and the manufacture of large-scale refrigerators have been carried out in the world. No matter at home or abroad, the use of vacuum insulation parts in refrigerators has been rapidly developed. The vacuum heat insulator works by, for example, covering a core material having a fine and connected space inside glass wool or silica powder with an outer envelope having gas barrier properties and by depressurizing and sealing the inside of the outer envelope to manufacture. [0003] For the purpose of large refrigerators, in order to reduce the insulation thickness of the refrigerator, it is necessary to improve the initial performance of the insulation to be used in terms of obtaining energy-saving performance...
