REFRIGERATOR WITH A HEATED HOUSING FRAME Russian patent published in 2022 - IPC F25D21/04 

FIELD: refrigeration equipment.

SUBSTANCE: invention relates to refrigeration equipment. The refrigeration unit contains a prefabricated profile consisting of three ring profiles. The internal removable profile (5) has a U-shaped protrusion (10) in contact with the rear wall of the front part of the housing with clamps (11) located on the inner side walls of the protrusion, and a catcher (12) of the outer end walls (13) of the doorway of the housing located in the groove (14) of the catcher located on different sides of the U-shaped protrusion, and the catcher (15) of the front wall (16) of the doorway of the housing located in the groove (17) of the catcher. The middle removable profile (6) is made in the form of a strip (18) with stops located perpendicular to the strip on both sides of the strip. Moreover, two stops located on one side of the strip have latches (21) at the end that interact with the clamps when connecting the middle and inner profiles, and the stops (22) located on the other side of the strip have the same length, on the extreme of which shelves (23), (24) are located parallel to the strip. The external removable profile is made in the form of a strip (25) with a chamber (26) with a magnet (9) placed in it, a latch (27) is located at one end of the strip, and an installation protrusion (28) on the other, interacting respectively with small and large shelves when connecting the outer and middle profiles to form, at least two chambers. At the same time, an electric heating wire (8) is placed in at least one chamber, and a chamber with a magnet is placed between two adjacent stops (30) of the middle profile.

EFFECT: reliability and safety are improved, the design of the refrigeration unit is simplified.
