Description

A refrigerator comprising a vacuum space

The present invention relates to a refrigerator having a vacuum space, and more particularly, to a refrigerator capable of improving the thermal insulation function of the refrigerator by forming a vacuum space between the outer case and the inner case constituting the main body.

A refrigerator is an electric product that can store a stored object refrigerated or frozen by maintaining the temperature of a storage room at an image or sub-zero temperature using a refrigerant cycle.

A general configuration of a refrigerator includes a main body in which a storage space for storing stored objects is formed, and a door disposed rotatably or slidably in the main body to open and close the storage space.

The main body includes an inner case in which a storage space is formed and an outer case in which the inner case is accommodated, and an insulating material is disposed between the inner case and the outer case.

The heat insulator prevents the temperature in the storage space from being affected by the external temperature.

Urethane foaming materials are widely used as the insulating material, and liquid urethane was injected into the space between the inner case and the outer case to foam-molded.

However, in order to realize the insulation effect by using the insulation material, the thickness of the insulation material must be secured to a certain extent, which means that the insulation material becomes thicker, and the wall thickness between the inner case and the outer case naturally becomes thicker, so that the size of the refrigerator becomes that much. It gets bigger.

However, in recent years, the tendency of refrigerators to become more compact has emerged, and there has been a need for a structure in which the volume of the internal storage space can be increased and the external size can be reduced than before.

US patent publication US2000882 (1935.05.07.)

The present invention has been conceived to solve the above-described conventional problem, and provides a refrigerator capable of increasing the thermal insulation effect by forming a vacuum space between the inner case and the outer case, while minimizing the external volume. have.

In addition, it is an object to provide a refrigerator having a support structure capable of maintaining the space between the inner case and the outer case without being deformed by an external impact while a vacuum space is formed between the inner case and the outer case.

A refrigerator having a vacuum space part of the present invention for achieving the above object includes a body having a storage space in which a predetermined storage material can be accommodated, wherein the body is an inner case in which the storage space is formed inside Wow; An outer case accommodating the inner case and disposed to be spaced apart from the inner case by a predetermined distance; A vacuum space part provided between the inner case and the outer case, the inside of which is sealed and maintained in a vacuum state to perform an adiabatic action between the inner case and the outer case; A first support plate provided on one of the surfaces of the inner case and the outer case facing each other; And a plurality of spacers fixedly disposed on the first support plate to support the inner case and the outer case to maintain a space therebetween.

It is preferable that the main body further includes a second support plate provided on the other surface of the inner case and the outer case facing each other and disposed to face the first support plate.

It is preferable that the second support plate includes a plurality of grooves formed on an inner surface thereof such that end portions of the plurality of spaces are inserted.

It is preferable that the plurality of spacers are arranged in a plurality of rows vertically and horizontally.

It is preferable that the ends of the plurality of spacers have a convex curved shape.

It is preferable that the plurality of grooves of the second support plate have a concave curved shape corresponding to the shape of the plurality of spacers.

The spacer, the first support plate, and the second support plate are preferably made of any one of metal, ceramic, and reinforced plastic.

In addition, it is preferable that the main body further includes a metal coating part for blocking radiant heat transfer on at least one side of an outer surface of the first support plate and an inner surface of the second support plate.

Further, the first support plate may have a plurality of perforations formed between the plurality of spacers in the inner edge of the first support plate.

In addition, the first support plate includes a perforation portion formed in a portion surrounded by an edge portion and a plurality of spacers disposed along the edge portion, and a plurality of first support plates connecting the plurality of spacers in a first direction at the perforation portion. A rib and a plurality of second ribs formed to cross the plurality of first ribs and connecting the plurality of spacers in a second direction at the perforation portion may be included.

Here, the first support plate may further include a plurality of reinforcing ribs connecting the plurality of spacers between the first rib and the second rib.

According to the refrigerator of the present invention as described above, a vacuum space portion is formed between the inner case and the outer case, rather than a conventional heat insulating material, and the heat transfer between the inner case and the outer case is suppressed by the vacuum space portion.

Since the heat insulation effect in a vacuum state is remarkably superior to the heat insulation effect of a conventional heat insulating material, the refrigerator according to the present invention has the advantage of excellent heat insulation than the conventional refrigerator.

On the other hand, in the case of the vacuum space, heat insulation is achieved if only the vacuum state is maintained regardless of its thickness (the gap between the inner case and the outer case). The increase in thickness leads to an increase in the size of the refrigerator.

Accordingly, the refrigerator according to the present invention can reduce the size of the outer case portion while maintaining the same storage space as compared with the conventional refrigerator, thereby contributing to the compactness of the refrigerator.

Further, according to the refrigerator of the present invention, even though a vacuum space is formed between the inner case and the outer case, the inner case and the outer case are not deformed by an external shock, and the gap can be maintained.

By providing a structure capable of easily assembling the inner case and the outer case forming the vacuum space, and supporting parts therebetween, workability is improved.

Can be applied to refrigerators. In addition, of course, it may be applied to a refrigerator including only a refrigerating chamber or a freezing chamber, or a refrigerator further including a separate cooling chamber in addition to the refrigerating chamber and the freezing chamber.

Looking at the structure of the main body 1, an inner case 110 in which the storage space is formed inside; An outer case 120 in which the inner case is accommodated and disposed to be spaced apart from the inner case by a predetermined distance; A vacuum space unit 130 provided between the inner case and the outer case, the inner case being sealed and maintained in a vacuum state to perform an adiabatic action between the inner case and the outer case; A first support plate 160 provided on one of the surfaces of the inner case 110 and the outer case 120 facing each other; It includes a plurality of spacers 150 fixedly disposed on the first support plate to support the inner case 110 and the outer case 120 to maintain a space between the inner case 110 and the outer case 120.

The outer case 120 and the inner case 110 are disposed to be spaced apart from each other, and a separate insulating material is not disposed in this space, but is only maintained in a vacuum state to perform heat insulation.

That is, the vacuum space 130 is formed between the outer case 120 and the inner case 110, so that the medium mediating heat transfer between the inner case 110 and the outer case 120 is removed. Keep.

Accordingly, it is possible to prevent heat of the hot air outside the outer case 120 from being transferred to the inner case 110 and the inside thereof.

A plurality of spacers allowing the vacuum space 130 between the inner case 110 and the outer case 120 to maintain a gap between the inner case 110 and the outer case 120 in order to maintain the shape (spacer) 150 is placed. The plurality of spacers 150 are disposed and supported so as to maintain a gap between the inner case 110 and the outer case 120.

A plurality of the plurality of spacers 150 should be fixed between the inner case 110 and the outer case 120, and the plurality of spacers 150 are provided with the first support plate 160 as a structure for fixing them. Is placed in

Since the first support plate 160 is in contact with the outer surface of the inner case 110, and the second support plate 170 is in contact with the inner surface of the outer case 120, the plurality of spacers 150 As a result, the inner case 110 and the outer case 120 are supported so as to maintain a gap therebetween.

In the case of the embodiment shown in FIG. 2, although the first support plate 160 and the second support plate 170 are disposed to be spaced apart by a predetermined distance, as shown in FIG. 1, a plurality of spacers 150 are integrally fixed. Only the disposed first support plate 160 may be provided between the inner case 110 and the outer case 120.

In this case, when the second support plate 170 is not present, the ends of the plurality of spacers 150 will be disposed to directly contact the inner surface of the outer case 120.

Meanwhile, in FIG. 1, for convenience, the inner case 110, the outer case 120, and the spacer 150 are illustrated with the first support plate 160 and the second support plate 170 omitted.

As shown, it is preferable that the plurality of spacers 150 are arranged in a plurality of rows vertically and horizontally.

A plurality of spacers 150 integrally formed and disposed on the first support plate 160 are arranged in rows in vertical and horizontal directions, as shown in FIGS. 3 and 4.

Since the plurality of spacers 150 are arranged in a plurality of rows in this way, not only is it easy to design and manufacture, but also assemble work is easy, and the strength to withstand vacuum pressure or external shock in the vacuum space unit 130 after assembly is increased. It can be bigger.

In addition, it is preferable that the ends of the plurality of spacers 150 have a convex curved shape.

As shown in the enlarged circle of FIG. 4, by forming the end of the spacer 150 in a convex curved shape, the end of each spacer 150 is in the groove 175 formed in the second support plate 170 when assembling. Because it is easily seated, the assembly work can be much easier.

In addition, it is more preferable that the plurality of groove portions 175 of the second support plate 170 have a concave curved shape corresponding to the shape of the plurality of spacers 150.

Since the plurality of grooves 175 of the second support plate 170 are formed in a shape corresponding to the shape of the plurality of spacers 150, positioning is easy during assembly and the second support plate 170 is It can be fixed so that it does not move in a direction parallel to its surface.

The spacer 150, the first support plate 160, and the second support plate 170 may be made of any one of metal, ceramic, and reinforced plastic.

The spacer 150 is provided in the vacuum space 130 between the inner case 110 and the outer case 120, and the first support plate 160 and the second support plate 170 are the inner case 110 And the outer case 120 are in contact with each other.

Therefore, it is necessary to minimize heat transfer from the outside of the outer case 120 to the inside of the inner case 110, and external heat is conducted through the second support plate 170, the spacer 150, and the first support plate 160. I can.

Thus, the spacer 150, the first support plate 160, and the second support plate 170, which are provided to contact between the inner case 110 and the outer case 120, are metal and ceramic materials having low thermal conductivity, respectively. It is desirable to be made of any one of reinforced plastics.

Among them, since it is preferable to fabricate the spacer or the like from a material having low thermal conductivity and excellent strength, it would be more preferable to fabricate the spacer or the like from a metal having excellent strength but relatively high thermal conductivity among the materials.

Meanwhile, the main body 1 may further include a metal coating for blocking radiant heat transfer on at least one side of an outer surface of the first support plate 160 and an inner surface of the second support plate 170.

Although not shown in the drawings, the metal coating portion is coated with metal on at least one side of the outer surface of the first support plate 160 and the inner surface of the second support plate 170, and the inner case 110 and the outer case ( 120) to minimize heat transfer by radiation.

In the case of metal, since it has excellent properties of blocking radiant heat transfer, it is coated with metal to minimize radiant heat transfer despite having relatively high thermal conductivity in general.

In order to minimize radiant heat transfer, it is preferable that the metal coating is provided on both the outer surface of the first support plate 160 and the inner surface of the second support plate 170.

Hereinafter, two other embodiments of the first support plate will be described with reference to FIGS. 5 and 6.

First, FIG. 5 shows a first support plate 260 in which a plurality of spacers 150 are integrally formed and disposed according to a second embodiment of the present invention.

In this embodiment, the difference from the first support plate 160 according to the first embodiment described above is that the first support plate 260 has a plurality of perforations 262 between the plurality of spacers 150 toward the inside of the edge thereof. Is formed.

The reason for forming the plurality of perforations 262 in the first support plate 260 in this way is that fine atoms on the surface of the first support plate 260 by vacuum pressure in the first support plate 260 in the vacuum space 130 Or, it is to prevent outgassing in which molecules are protruding.

In other words, by reducing the surface area of the first support plate 260, the material itself that can cause outgassing is reduced.

Of course, by forming the plurality of perforations 262 in the first support plate 260, not only the material cost for forming the first support plate can be reduced, but also the weight thereof can be reduced.

As shown in FIG. 5, since the plurality of spacers 150 are arranged in a plurality of rows vertically and horizontally, the plurality of perforations 262 have four vertices adjacent to the spacers 150. It consists of a rectangular shape positioned so as to be.

Of course, the shape of the perforated portion 262 is not limited to such a rectangular shape, and may be formed in other shapes such as hexagonal, octagonal, or elliptical.

However, the plurality of perforations 262 may have sufficient strength to support the spacers 150 without interfering with the plurality of perforations 262 in consideration of the positions where the plurality of spacers 150 are disposed. Will have to form.

Further, the plurality of perforations 262 formed in the first support plate 160 are arranged inside the edge portion 261 of the first support plate 160.

A first rib 263 connecting the spacers 150 in the horizontal direction and a second rib 264 connecting the spacers 150 in the vertical direction are formed between the plurality of perforations 262, have.

The plurality of spacers 150 may be disposed at a point where the first rib 263 and the second rib 264 intersect or the two ribs intersect the edge portion 261, as shown in FIG. 5. desirable.

It is preferable that the edge portion 261 of the first support plate 160 is formed to have a width greater than that of the first rib 263 and the second rib 264.

This is because the edge portion 261 forms the entire skeleton of the first support plate 160 and provides basic strength.

In addition, the second support plate 170 illustrated in FIGS. 2 to 4 may also have a plurality of perforations formed in the same manner as the first support plate 260 illustrated in FIG. 5.

In this case, the second support plate 170 will preferably have the same shape corresponding to the first support plate 260. Of course, the plurality of grooves 175 described above may be formed in the second support plate 170.

Finally, FIG. 6 shows a first support plate 360 in which a plurality of spacers 150 are integrally formed and disposed according to the third embodiment of the present invention.

In this embodiment, the difference from the first support plate 260 according to the second embodiment described above is that the first support plate 360 is inside the perforated portion 362 surrounded by a plurality of ribs 363 and 364. It means that it further includes a reinforcing rib 365 connecting two or more spacers 150.

That is, in the third embodiment, the first support plate 360 includes an edge portion 361, a perforation portion 362 formed in a portion surrounded by a plurality of spacers 150 disposed along the edge portion, and the cloth. In the study, a plurality of first ribs 363 connecting the plurality of spacers in a first direction, and a plurality of first ribs 363 connecting the plurality of spacers in the second direction in the perforation portion and crossing the plurality of first ribs A second rib 364 may be included, and a plurality of reinforcing ribs 365 for connecting the plurality of spacers between the first rib and the second rib may be further included.

For convenience, in the third embodiment, the perforated portion 362 is formed in a portion surrounded by a plurality of spacers 150 disposed along the edge portion 361, unlike the perforated portion 262 in the second embodiment. As referring to a part, it is defined as indicating a rectangular part formed by an imaginary outline excluding the ribs 363, 364, 365.

However, as a result, it will be understood that the first support plate 360 of the third embodiment has the same shape as the first support plate 260 of the second embodiment except for the reinforcing ribs 365.

The reinforcing rib 365 may be formed to connect between two spacers disposed in a diagonal direction among the plurality of spacers 150. Thus, the two reinforcing ribs 365 are formed so as to cross each other at the intermediate portion.

In addition, if a shape capable of reinforcing the strength of the first support plate 360 in which the plurality of spacers 150 are integrally formed, it is connected in a direction parallel to the first rib 363 or the second rib 364. Of course, it can be made in other forms, such as.

Since the above-described first support plates 160, 260, and 360 and second support plates 170 are formed integrally with each other, regardless of their shape, it is preferable that they are molded and manufactured at one time in a mold made in a predetermined shape.

According to the refrigerator according to the present invention, it is very easy to assemble a plurality of spacers by inserting a plurality of spacers in the vacuum space between the inner case and the outer case, and may have a structure capable of sufficiently withstanding vacuum pressure.

In the above, preferred embodiments of the present invention have been described, but the scope of the present invention is not limited only to such specific embodiments, and those of ordinary skill in the relevant field will appropriately fall within the scope described within the scope of the claims of the present invention. Changes will be possible.
