A refrigeration device, in particular a refrigerator and/or freezer, includes a housing with a top, a base, lateral walls and a rear wall as external walls, a door, an interior compartment situated in the housing and surrounded by internal walls and a front frame for thermally decoupling the internal walls from the external walls, the lateral walls being thermally insulated from the other walls by an additional insulation strip. The invention is characterized in that the entry of heat from the exterior into the interior compartment via the lateral walls can be significantly reduced by the thermal decoupling of the lateral walls, thus significantly increasing the efficiency of the refrigeration device.

1. A refrigeration device, including at least one of a refrigerator and a freezer, the refrigeration device comprising: a housing including a top, a base, a plurality of lateral walls and a rear wall forming outer walls;an inner chamber located in the housing which is formed by inner walls, with the inner walls being fitted in a nested relationship with the outer walls and defining an access opening to the inner chamber;a door for selectively covering the access opening;a front frame disposed intermediate the inner walls and the outer walls for thermally decoupling the inner walls from the other walls, the front frame being exposed as an external surface of the housing; andat least one insulating member disposed in an operative relationship with at least one of said lateral walls for thermally insulating the at least one lateral wall from the other walls,wherein the front frame has a U shape including a first leg of the U shape and a second leg of the U shape separated by a base portion, and wherein a first end portion of the first leg is connected to the inner walls by at least one connection element and a second end portion of the second leg is connected to the at least one insulating member. 2. The refrigeration device according to claim 1 wherein the at least one insulating member includes a mounting element, the mounting element being formed as one of a groove and a structure not formed as a groove, for accepting at least one of the lateral walls, the top and the base. 3. The refrigeration device according to claim 1 wherein the at least one insulating member includes a second mounting element, the mounting element being formed as one of a groove and a structure not forming a groove, for accepting the front frame. 4. The refrigeration device according to claim 1 wherein the at least one insulating member includes a mounting element, the mounting element being formed as one of a clip element and not a clip element, for accepting a reinforcement frame. 5. The refrigeration device according to claim 4 wherein the reinforcement frame includes means for strengthening the housing and the door is hingedly mounted onto the reinforcement frame. 6. The refrigeration device according to claim 5 wherein the reinforcement frame includes profile bars which include a plurality of openings extending there through for contacting the insulating member with insulating foam. 7. The refrigeration device according to claim 1 wherein the at least one insulating member further comprises a plurality of ribs including at least one of support ribs and spacer ribs for reducing the heat conductivity between the lateral walls and at least one of the other walls and at least one reinforcement frame is disposed on the insulating member. 8. The refrigeration device according to claim 7 wherein the length of at least one of the support ribs is at least 50% of the distance between the lateral wall and the adjacent at least one of the other walls, such that a heat transfer path between the lateral wall and at least one of the adjacent other wall and the reinforcement frame is extended by at least 50% by the at least one of the support ribs and the spacer ribs. 9. The refrigeration device according to claim 7 wherein the length of at least one of the support ribs is at least the distance between the lateral wall and the adjacent at least one of the other walls, such that a heat transfer path between the lateral wall and at least one of the adjacent other wall and the reinforcement frame is extended by at least 100% by the at least one of the support ribs and the spacer ribs. 10. The refrigeration device according to claim 7 wherein the length of at least one of the support ribs is at least twice the distance between the lateral wall and the adjacent at least one of the other walls, such that a heat transfer path between the lateral wall and at least one of the adjacent other wall and the reinforcement frame is extended by at least 200% by the at least one of the support ribs and the spacer ribs. 11. The refrigeration device according to claim 1 wherein the at least one insulating member is disposed between the at least one lateral wall and the front frame and connects the lateral wall to the front frame. 12. A refrigeration device, including at least one of a refrigerator and a freezer, the refrigeration device comprising: a housing including a top, a base, a plurality of lateral walls and a rear wall forming outer walls;an inner chamber located in the housing which is formed by inner walls, with the inner walls being fitted in a nested relationship with the outer walls and defining an access opening to the inner chamber;a door for selectively covering the access opening;a front frame disposed intermediate the inner walls and the outer walls for thermally decoupling the inner walls from the other walls;at least one insulating member disposed in an operative relationship with said lateral walls for thermally insulating the lateral walls from the other walls; anda reinforcement frame to provide structural support to the housing, the reinforcement frame being connected to at least one of the lateral walls,wherein the at least one insulating member includes a plurality of spaced-apart ribs protruding from a surface thereof to abut against a common surface of 1 ) the reinforcement frame or 2) at least one of the other walls to increase a distance between 1) the lateral walls and 2) the reinforcement frame and/or at least one of the other walls to thereby reduce a heat conductivity between 1) the lateral walls and 2) the reinforcement frame and/or at least one of the other walls. 13. The refrigeration device according to claim 12, wherein the at least one insulating member includes a mounting element, the mounting element being formed as one of a groove and a structure not formed as a groove, for accepting at least one of the lateral walls, the top and the base. 14. The refrigeration device according to claim 12, wherein the at least one insulating member includes a second mounting element, the mounting element being formed as one of a groove and a structure not forming a groove, for accepting the front frame. 15. The refrigeration device according to claim 12, wherein the at least one insulating member includes a mounting element, the mounting element being formed as one of a clip element and not a clip element, for accepting the reinforcement frame. 16. The refrigeration device according to claim 15, wherein the ribs are arranged to abut against the reinforcement frame. 17. The refrigeration device according to claim 12, wherein the at least one insulating member includes sealing fins to seal the housing during a filling procedure to prevent insulating foam from escaping the housing. 18.
