Abstract

The invention relates to domestic refrigerators and relates to the design and placement of devices for installing heating elements that prevent the exterior surface of the refrigerator from becoming dampened. In the slots (P), made in the heat insulation of the body, respectively, of the vertical and horizontal partitions, holders (D) of elastic elastic material, such as polyvinyl chloride, are installed. In one of the sockets (D) of the holder, a heating element (NE) 12 is placed. In the recess 13, made in D opposite to this D, a locking tab 14 of the latch 13 is placed, which ensures that the NE 12 is pressed against the front plane of the partition. When D is installed in the slots of the housing or the vertical partition, the pressure of the ne 12 is carried out by a sealing insert 16 and an elastic tongue 18. 5 sludge. s- SS (L in g / Co JV 4 O O SL

Description

The invention relates to domestic refrigerators, the installation of heating elements in them, which ensure that the outer surface of the refrigerator is not allowed to sweat.

The aim of the invention is to improve the usability and expansion of technological capabilities.

FIG. 1 shows the cooling cabinet without doors, front view; in fig. 2 - the holder; in fig. 3 shows section A-A in FIG. 1 (placement of the holder in the slots of the housing); in fig. 4 shows a section BB in FIG. 1 (placing the holder in a vertical partition); in fig. 5 shows a section B-B in FIG. 1 (placing the holder in a horizontal partition).

The refrigerator contains a double-walled case with walls 1 and 2 with thermal insulation 3 and a decorative lining 4. The case is divided into low-temperature and refrigerating chambers by vertical and horizontal partitions 5 and 6, each of which consists of two walls 7 and 8 with thermal insulation 3 between them. In the slots 9-11, made in the thermal insulation of the body of the scaffold, the vertical and horizontal partitions on the side of the doorway, the heating element 12 is placed. In the groove 11 of the horizontal partition 6 there is a latch 13 with a locking element 14. elastic material, such as polyvinyl chloride, and sealing inserts 16. Each holder 15 has two slots 17, opposite one slot 17, an elastic tongue 18 to clamp and fix the heating element in the groove 10 vertically th partition 5 and in the grooves 9 of the outer walls meter cabinets housing. Opposite the other socket 17, a recess is made to place the locking element of the latch in the groove 11 of the horizontal partition 6.

The holder 15 when installing it in the grooves

The outer housing (FIG. 3) is placed so that the heating element 12, placed in the slot 17 of the holder 15, faces the plane of the door opening of the housing. The clamping of the heating element 12 is provided with an elastic tongue 18. The sealing insert 16 performs heat insulating functions.

The holder 15 when installing it in the grooves

The vertical partition 5 (FIG. 4) is rotated 90 °, and the heating element 12 is placed in another slot 17 of the holder 15 and facing the plane of the door opening. In this case, the seal-insert 16 and the elastic tongue 18 provide clamping of the heating element 12.

When installing the holder 15 into the groove 11 of the horizontal partition 6 between the chambers (FIG. 5), the heating clamp

the element 12 to the plane 9 of the element of the outer casing is provided with a latch 13, the fixing element 17 of which enters the recess 19 of the holder 15.

The anti-sweat device operates as follows.

Heating elements 12, located in the grooves around the perimeter of the low-temperature chambers, are included in the electrical circuit of the refrigerator.

If there is an increased humidity and temperature on the front plane of the chambers with negative temperatures in the room where the working household refrigerator is installed, moisture is lost due to the large temperature difference between the room air and the air of these chambers.

By switching on the heating elements 12, a smaller temperature difference is created between the air of the displacement and the air of the chambers, which prevents moisture loss on the front plane of the outer Icaf. If necessary, individual heating elements can be replaced. To replace the heating elements 12 installed in the grooves 9 of the outer casing (Fig. 3), it is necessary to remove the decorative strip 4, the sealing insert and disconnect the heating element 12. Assembly after replacing the heating element 12 is carried out in the reverse order.

To replace the heating elements 12 installed in the slots 10 of the vertical partition 5 (Fig. 4), it is necessary to remove the decorative strip 4 and disconnect the heating elements 12. Assembly after replacing the heating elements 12 is carried out in the reverse order.

In order to replace the heating element 12 installed in the groove 11 of the horizontal partition 6 between the chambers (Fig. 5), it is necessary to remove the latch 13 and disconnect the heating element 12. Assembly after replacing the heating element 12 is carried out in the reverse order.

The device for preventing the cabinet from misting down ensures reliable contact of the heater over the entire front surface of the outer casing, maintainability and quick replacement of out-of-date heaters, i.e. improves usability. The constructive design of the holder allows the use of one type of holder profile for all cases of mounting the holder with a heating element in different slots of the refrigerator.
