When realizing the connection of the support bracket 40 with the connecting plate 50, first of all, the fixing bar 41 located on the supporting bracket 40 is placed in the fixing hole 51 located on the connecting plate 50. The seating portion 411 provided on the fixing bar 41 does not allow the fixing the lug 41 to disengage from the fixing hole 51 when landing on the connecting plate 50. After that, the positioning bar 52 provided on the connecting plate 50 is placed in the positioning opening 42, provided on the support bracket 40. As a result of these two movements, mounting holes 43, 53 provided on the support bracket 40 and on the connecting plate 50 are aligned with each other. After that, the mounting holes 43, 53 are connected to each other using a connecting element 70. A support 60 comprising a cylindrical portion 62 with a groove formed on a side surface of the support is introduced into the adjustment hole 44, starting from part 62 of the support 60 with a groove; by rotation, the support 60 is set to such a height that will ensure contact of the landing section 63 on the supporting part 61 (on the one hand) with the base. The supporting part 61 is designed so that its design is compatible with the locking edge.

An embodiment of the invention, characterized by a simpler and more reliable assembly of the household appliance using the passage between the cardboard pad and the connecting plate, is shown in figures 6-11.

In this detailed embodiment, the cooling device comprises a housing 10, an insert 90 is provided inside the housing 10, and an insulating material 100 is introduced between the housing 10 and the insert 90.

As shown in FIG. 6, a pin 45 is provided at one end of the support bracket 40, oriented substantially perpendicularly to the support bracket 40. The hinge support 80 is placed on said pivot 45 to connect to the door 20, for example, the hinge support 80 is mounted on the pivot. An adjustment hole 44 is provided that is adjacent to the spigot 45 and can be engaged with a support 60.
