초록

A refrigerator includes a vacuum insulated cabinet structure having side walls that are formed from a tube that has been folded/deformed into a structure having an “O” shape with vertically enlarged front and rear openings. The interior of the tube may be filled with silica powder or other filler, and a vacuum is formed within the tube. An insulated rear panel may be utilized to close off the rear opening of the vacuum insulated cabinet structure.

1. A free-standing vacuum insulated refrigerator housing structure comprising: a pair of horizontally spaced apart upright primary side walls, each primary side wall defining upper and lower end portions and spaced apart inner and outer side walls and spaced apart front and rear edge walls extending transversely between the inner and outer side walls such that each primary upright side wall forms a dosed tubular section defining a vertically extending interior space;a horizontally extending upper side wall having an interior space and including opposite ends connected to the upper end portions of the primary upright side walls;a horizontally extending lower side wall having an interior space and including opposite ends connected to the lower end portions of the primary upright side walls;porous insulating material disposed in the interior spaces of the primary upright side walls, the upper side wall, and the lower side wall;wherein the primary upright side walls and the upper and lower side walls comprise a one piece integral tubular structure defining an insulated interior space, wherein the one piece integral tubular structure has a front perimeter extending around a front opening that provides access to the insulated interior space and wherein the interior spaces of the primary side walls, the upper side wall, and the lower side wall have a vacuum formed therein; andat least one door movably connected to the one piece integral tubular structure whereby the at least one door at least partially closes off the front opening when the at least one door is in a closed position, and wherein the at least one door provides access to the insulated interior space through the front opening when the at least one door is in an open position. 2. The free-standing vacuum insulated refrigerator housing structure of claim 1, wherein: the one piece integral tubular structure comprises metal. 3. The free-standing vacuum insulated refrigerator housing structure of claim 2, wherein: the one piece integral tubular structure comprises low carbon steel. 4. The free-standing vacuum insulated refrigerator housing structure of claim 2, wherein: the one piece integral tubular structure comprises aluminum. 5. The free-standing vacuum insulated refrigerator housing structure of claim 1, wherein: the one piece integral tubular structure comprises a polymer material. 6. The free-standing vacuum insulated refrigerator housing structure of claim 5, wherein: the one piece integral tubular structure comprises a thermoplastic polymer material that is co-extruded with a layer of impermeable polymer material. 7. A free-standing vacuum insulated refrigerator housing structure comprising: a pair of horizontally spaced apart upright side walls defining upper and lower end portions and an airtight interior space;a horizontally extending upper side wall having an airtight interior space and including opposite ends connected to the upper end portions of the upright side walls;a horizontally extending lower side wall having an airtight interior space and including opposite ends connected to the lower end portions of the upright side walls;porous insulating material disposed in the airtight interior spaces of the upright side walls, the upper side wall, and the lower side wall;wherein the upright side walls and the upper and lower side walls comprise a one piece integral tubular structure defining an insulated interior space, wherein the one piece integral tubular structure has a front perimeter extending around a front opening that provides access to the insulated interior space and wherein the airtight interior spaces of the side walls, the upper side wall, and the lower side wall have a vacuum formed therein; andat least one door movably connected to the one piece integral tubular structure whereby the at least one door at least partially closes off the front opening when the at least one door is in a closed position, and wherein the at least one door provides access to the insulated interior space through the front opening when the at least one door is in an open position;the one piece integral tubular structure has a rear perimeter extending around a rear opening; and including:an upright rear panel extending over the rear opening. 8. The free-standing vacuum insulated refrigerator housing structure of claim 7, wherein: the one piece integral tubular structure defines a rearwardly-facing surface extending around the rear opening; andthe upright rear panel is disposed against the rearwardly-facing surface. 9. The free-standing vacuum insulated refrigerator housing structure of claim 8, wherein: the rearwardly-facing surface is planar. 10. The free-standing vacuum insulated refrigerator housing structure of claim 7, wherein: the upright rear panel includes an insulated divider that divides the insulated interior space into first and second spaces. 11. The free-standing vacuum insulated refrigerator housing structure of claim 10, wherein: the insulated divider extends vertically.
