This U.S. nonprovisional patent application asserts the benefit of Korean Patent Application No. 10-2021-0111183 filed on August 23, 2021, pursuant to 35 U.S.C. § 119, the entire contents of which are hereby incorporated by reference.

Invention background

The present disclosure is related to a vacuum insulation plate and a system for detecting the vacuum insulation plate, and more specifically, to a vacuum insulation plate that facilitates vacuum level detection and a system for detecting the vacuum insulation plate.

Generally, vacuum insulation panels are made of microporous insulation materials and have extremely low thermal conductivity. The vacuum insulation panel is surrounded by a multi-layer film coated with aluminum using fumed silica as the inner material. The inner side of the vacuum insulation panel is vacuum treated to produce a panel with excellent thermal conductivity.

In the process of measuring the vacuum degree of the vacuum insulation plate, according to the related art, a method has been used to apply reverse vacuum after inserting the vacuum insulation plate into a vacuum processing chamber to measure the displacement difference caused by the pressure difference between the inside and outside of the chamber during volume expansion. However, as the size of the product increases, the size of the chamber must also increase. Therefore, when measuring the vacuum degree, there is a limitation that the measurement time requires a long period of time. Therefore, in the process of measuring the vacuum degree of the vacuum insulation plate, a device for detecting the vacuum insulation plate is being studied, which can more easily save manufacturing costs and improve productivity.

For example, the vacuum insulation panel I may be an insulation panel in which the internal pressure is vacuum-treated to about 5 mbar or less. The vacuum insulation panel I may be used in various places where thermal insulation is required. For example, the vacuum insulation panel I may be used to insulate the inside and outside of a storage box. However, an embodiment of the present inventive concept is not limited thereto, and the vacuum insulation panel I may be used for various other purposes.

The vacuum insulation plate 1 may include a core material 1, a shell material 3, and a vacuum measuring component 5 (see FIG. 2, etc.).

In one embodiment, the shell material 3 can include an aluminum foil film, wherein a polyethylene terephthalate (PET) film is attached to the aluminum foil, but is not limited thereto.

The vacuum measuring component 5 will be described later with reference to Figures 2 to 5.

Referring to FIG. 2 , the vacuum measuring component 5 can be disposed between the core material 1 and the shell material 3. The vacuum measuring component 5 can include a supporting member 51 and a magnetic coupling member 53.

Referring to Figure 3, the core material 1 may include a top surface 11, a recessed surface 13, and a connecting surface 15. The top surface 11 may include a flat surface. The recessed surface 13 may be recessed from the top surface 11 into the inner side of the core material 1. That is, the recessed surface 13 may be a flat surface set downward from the top surface 11 to a predetermined depth. In an embodiment, the recessed surface 13 may include a circular shape in a plan view, but is not limited thereto. The recessed surface 13 may define a recessed space 1h. That is, the core material 1 may provide the recessed space 1h through the recessed surface 13. The connecting surface 15 may connect the recessed surface 13 to the top surface 11. For example, the connecting surface 15 may extend from an edge of the recessed surface 13 along the first direction D1. In an embodiment, the connecting surface 15 may surround the concave space 1h. When the concave surface 13 includes the circular shape, the connecting surface 15 may surround the concave space 1h in the same shape as the side of a cylinder. The concave space 1h may be defined by the concave surface 13 and the connecting surface 15.

The vacuum measuring component 5 may include the supporting member 51 and the magnetic coupling member 53. The supporting member 51 may be disposed in the recessed space 1h. In more detail, the supporting member 51 may be disposed in the recessed space 1h in a state supported by the recessed surface 13. The supporting member 51 may include a material that is not magnetic. That is, the supporting member 51 may include a non-magnetic material. For example, the supporting member 51 may include ceramic and/or plastic. The magnetic coupling member 53 may include a magnetic material. For example, the magnetic coupling member 53 may include a metal. In more detail, the magnetic coupling member 53 may include iron (Fe), nickel (Ni) and/or neodymium alloy. However, an embodiment of the present inventive concept is not limited thereto. The magnetic coupling member 53 may be disposed on the supporting member 51. More specifically, the magnetic coupling member 53 may be disposed between the supporting member 51 and the shell material 3. The magnetic coupling member 53 may have a flat plate shape. A top surface of the magnetic coupling member 53 may contact the shell material 3.

FIG. 4 is a cross-sectional view illustrating the vacuum measuring component of the vacuum insulation plate according to an embodiment of the present invention, and FIG. 5 is a plan view illustrating the vacuum measuring component of the vacuum insulation plate according to an embodiment of the present invention.

Referring to FIG. 4 , the support member 51 may include a support plate 511 and a side wall 513. A bearing space 51h may be defined by the support plate 511 and the side wall 513. The support plate 511 may have a circular shape in a plan view. A bottom surface 511b of the support plate 511 may contact the recessed surface 13 (see FIG. 3 ). The shape of the bottom surface 511b of the support plate 511 may be substantially the same as or similar to the shape of the recessed surface 13. The support plate 511 may provide a through hole 511h to connect the top surface 511u to the bottom surface 511b. The through hole 511h may extend in the first direction D1. The through hole 511h may connect a space below the support plate 511 to the seating space 51h. Due to the through hole 511h, the atmospheric pressure in the space below the support plate 511 and the atmospheric pressure in the seating space 51h may be substantially the same or similar to each other. In an embodiment, a plurality of through holes 511h may be provided. Each of the plurality of through holes 511h may be spaced apart from each other in the second direction D2 and/or the third direction D3. The side wall 513 may extend from the support plate 511 along the first direction D1. In an embodiment, the side wall 513 may include a cylindrical shape. The seating space 51h may be defined by an inner surface 513i of the side wall 513 and the top surface 511u of the support plate 511. In an embodiment, when the supporting member 51 is disposed in the recessed space 1h (see FIG. 3 ), the top surface 513u of the side wall 513 may be disposed on the same plane as the top surface 11 of the core material 1. An outer surface 513e of the side wall 513 may contact the connecting surface 15.

The magnetic coupling member 53 may be disposed in the seating space 51h. In more detail, a bottom surface 53b of the magnetic coupling member 53 may be in contact with the top surface 511u of the support plate 511. In a state where the magnetic coupling member 53 is seated on the support plate 511, a level of the top surface 53u of the magnetic coupling member 53 may be lower than a level of the top surface 513u of the side wall 513. Therefore, the level of the top surface 53u of the magnetic coupling member 53 may be lower than a level of the top surface 11 of the core material 1. In an embodiment, the width of the magnetic coupling member 53 may be smaller than the width of the seating space 51h. Therefore, a side surface 53s of the magnetic coupling member 53 can be separated from the inner surface 513i of the side wall 513.

Referring again to FIG. 2 , the magnetic coupling member 53 may be in contact with the shell material 3. When the level of the top surface of the magnetic coupling member 53 is lower than the level of the top surface of the core material 1, the shell material 3 may be recessed downward from an area on which the magnetic coupling member 53 is disposed. In some cases, the shell material 3 may also be inserted between the magnetic coupling member 53 and the side wall of the supporting member 51.

Figures 6 and 7 are cross-sectional views illustrating a system for detecting a vacuum insulation plate according to an embodiment of the present invention; referring to Figure 6, a system S for detecting the vacuum insulation plate may be provided. The system S for detecting the vacuum insulation plate may include a vacuum insulation plate I and an element 7 for detecting the vacuum insulation plate.

The vacuum insulation plate I may be substantially the same or similar to the vacuum insulation plate described with reference to FIGS. 1 to 5 .

The element 7 for detecting the vacuum insulation plate can detect the vacuum degree of the vacuum insulation plate I. In more detail, the element 7 for detecting the vacuum insulation plate can be arranged at one side of the vacuum insulation plate I to detect the vacuum degree of the vacuum insulation plate I. The element 7 for detecting the vacuum insulation plate can be arranged on an area on which the vacuum measuring component 5 is arranged, and is located on the vacuum insulation plate I. The element 7 for detecting the vacuum insulation plate can include a fixed component 71, a movable component 73, and an elastic member 75.

The fixing member 71 can fix the element 7 for detecting the vacuum insulation plate to the vacuum insulation plate I. For example, a user can press down the fixing member 71 to fix the element 7 for detecting the vacuum insulation plate at a predetermined position on the vacuum insulation plate I. The fixing member 71 can be movably coupled to the movable member 73. The fixing member 71 can include a support member 713 and an extension portion 711. The support member 713 can directly contact an outer surface of the vacuum insulation plate I. In more detail, the support member 713 can contact the shell material 3. The support member 713 can extend along the first direction D1. A plurality of support members 713 can be provided. Each of the plurality of supporting members 713 may be spaced apart from each other in the second direction D2 and/or the third direction D3. The extension portion 711 may be connected to the supporting member 713. The extension portion 711 may extend from a side of the supporting member 713 along a horizontal direction. The extension portion 711 may connect the plurality of supporting members 713 to each other. The extension portion 711 may provide an extension through hole 711h. The movable member 73 may be inserted into the extension through hole 711h. The movable member 73 may be movably coupled to the fixed member 71. In more detail, the movable member 73 may be movably coupled to the fixed member 71 through the elastic member 75. According to the compression of the elastic member 75, the movable member 73 may move along the first direction D1.

The movable part 73 may include a magnet 731, a force measuring element 733, an extension member 735 and a handle 737. The magnet 731 may be magnetically coupled to the magnetic coupling member 53. The magnet 731 may be coupled below the force measuring element 733. The magnetic coupling member 53 may be lifted upward by the magnet 731. The force measuring element 733 may be disposed above the magnet 731. The force measuring element 733 may measure the force applied to the force measuring element 733. In an embodiment, the force measuring element 733 may include a load cell or the like. The force measuring element 733 may output information about the measured force to the outside. For example, the force measuring element 733 may include a separate display (not shown) to display the measured force. Alternatively, the force measuring element 733 may transmit information about the measured force to an external display or the like. The extension member 735 may extend in the first direction D1. The extension member 735 may extend upward from the force measuring element 733. The extension member 735 may pass through the extension through hole 711h. To this end, a width of the extension member 735 may be less than a width of the extension through hole 711h. The handle 737 may be coupled to an upper side of the extension member 735. A width of the handle 737 may be greater than a width of the extension member 735.

The elastic member 75 may connect the fixed member 71 to the movable member 73. The elastic member 75 may extend along the first direction D1. The elastic member 75 may be compressed in the first direction D1. In an embodiment, the elastic member 75 may include a spring or the like. According to the compression and expansion of the elastic member 75, the movable member 73 may move vertically relative to the fixed member 71. The elastic member 75 may be coupled to a top surface of the force measuring element 733 and a bottom surface of the extension portion 711.

Referring to Figure 7, the movable part 73 can move vertically. In more detail, the handle 737 or the like can be used to apply force to the movable part 73 to allow the movable part 73 to move along the first direction D1. The process of applying force to the movable part 73 can be performed in various ways. For example, force can be applied to the movable part 73 via a separate power element (not shown), or the operator can pull the handle 737 upward by hand. When the movable part 73 is pulled upward, the elastic member 75 can be compressed. The elastic member 75 can be compressed in the first direction D1. The moving direction of the movable part 73 can be guided by the elastic member 75. When the magnet 731 moves upward, the magnetic coupling member 53 magnetically coupled to the magnet 731 may also move upward. When the magnetic coupling member 53 moves upward, the magnetic coupling member 53 may be spaced upward from the supporting member 51. At the same time, when the magnetic coupling member 53 moves upward, a portion of the casing material 3 may be lifted upward in a protruding manner. More specifically, the casing material 3 on the region disposed on the magnetic coupling member 53 may be lifted upward in a protruding manner. If a pressure lower than the atmospheric pressure is provided in the vacuum insulation panel, a force that overcomes the atmospheric pressure applied to the top surface of the casing material 3 may be required to lift the casing material 3 upward. When measuring the force required to lift the shell material 3, the pressure difference between the atmospheric pressure and the pressure in the vacuum insulation plate can be calculated. When the movable member 73 is lifted upward, the force measuring element 733 can receive the force in the first direction D1. The force measuring element 733 can measure the magnitude of the force applied in the first direction D1. The force applied to the force measuring element 733 may include the force generated by the air pressure difference between the top surface and the bottom surface of the shell material 3, the force according to a weight of the shell material 3, the force according to a weight of the magnetic coupling member 53, the force according to a weight of the movable member 73, the force according to a weight of the elastic member 75, and the elastic force according to the compression of the elastic member 75. The information of the force applied to the force measuring element 733 can be displayed on a separate display (not shown) or an external display (not shown). The force generated by the air pressure difference between the top and bottom surfaces of the casing material 3 can be calculated using the information about the force applied to the force measuring element 733 and the information about the weight of the casing material 3, the force according to the weight of the magnetic coupling member 53, the force according to the weight of the movable part 73, the force according to the weight of the elastic member 75, and the elastic force according to the compression of the elastic member 75. Information about the internal pressure of the vacuum insulation panel can be obtained using information about the force generated by the air pressure difference between the top and bottom surfaces of the shell material 3 and information about the force applied to the top surface of the shell material 3. When the internal pressure of the vacuum insulation panel exceeds a predetermined value, it can be determined that the thermal insulation performance of the vacuum insulation panel is insufficient. That is, whether the vacuum insulation panel is defective can be determined by using the information about the internal pressure of the vacuum insulation panel.

According to the system for detecting the vacuum insulation plate of the embodiment of the present invention, the vacuum degree of the vacuum insulation plate can be simply measured. That is, even without a vacuum pump or a pressure gauge, the vacuum degree inside the vacuum insulation plate can be measured as long as there is a magnet and a load cell. Since the measurement of the vacuum degree does not require bulky and expensive equipment, the vacuum degree can be simply measured at a relatively low cost. In addition, since the structure of the element used to detect the vacuum insulation plate is simple, anyone can quickly measure the vacuum degree of the vacuum insulation plate.

According to the system for detecting the vacuum insulation board of the embodiment of the present inventive concept, one side of the core material can be pressed to check the vacuum degree of the vacuum insulation board, and only the supporting member and the magnetic coupling member are provided. That is, the vacuum degree can be measured without having a complicated configuration inside the vacuum insulation board. Therefore, the vacuum insulation board itself can be easily manufactured and the price can be reduced. In addition, since it is sufficient if only a part of the core material is impregnated, the damage of the vacuum insulation board can be minimized to improve the insulation effect.

The external thread formed on the outer surface of the extension member 735' may engage with an internal thread formed on an inner circumferential surface of the extension through hole of the extension portion 711'. The movable part 73' can move in a spiral rotation relative to the fixed part 71'. When the movable part 73' moves in the spiral rotation, the force measuring element 733' can receive the force in the first direction D1.
