Description

The invention relates to domestic refrigerators with multi-temperature chambers and relates to the prevention of moisture condensation at the outer end of an inter-chamber thermally insulated partition.

A refrigerator is known comprising a thermally insulated body with different temperature chambers separated by a thermally insulated partition, doors for each of the chambers, a metal plate for interacting with magnetic door seals, mounted on the outer end of the partition, and a device for preventing condensation. Said device includes an additional seal fixed

on the inner surface of the chamber door with a relatively low temperature and forming an air channel with the main seal when the door is closed, and a thermally insulated partition is made with holes that connect the air channel with the chamber at a relatively high temperature.

The disadvantages of the known refrigerator are the design complexity and insufficient reliability during operation.

The purpose of the invention is to simplify the design and increase reliability during operation.

This is achieved in that in a refrigerator containing a thermally insulated body with different temperature and cameras,

separated by a heat-insulated partition, doors for each of the chambers, a metal plate for interacting with magnetic door seals, mounted on the outer end of the partition, and a device for preventing condensation, the specified attachment is made in the form of a longitudinal lpe6pa HlT.MJ &Target; iH4ecKOU the overlay located between the ends of the closed doors of the temperature chambers.

In this case, the overlay with a longitudinal edge is made in the form of a profiled part.

In addition, the end sections of the lining and the longitudinal rib are provided with T-shaped elements made with holes for fastening to the refrigerator body and the door hinge.

In FIG. 1 shows a two-chamber refrigerator, general view; in FIG. 2 - double-chamber refrigerator, section, fragment; in FIG. 3 - pad with a longitudinal rib and T-shaped elements; FIG. 4 - cabinet three-compartment refrigerator, General view.

The refrigerator contains a thermally insulated casing 1 with different temperature chambers 2 separated by a thermally insulated partition 3, and a door 4 for each chamber with magnetic seals 5. At the outer end of the partition 3, a metal plate 6 is mounted to interact with magnetic seals 5. The entire length of the plate b a longitudinal rib 7 was made, located in the gap between the ends of the closed doors of the temperature chambers. The overlay and the rib are a profiled part made of sheet material, the ends of which are equipped with T-shaped elements 8 with holes 9 for attaching to the refrigerator body and a hole 10 for installing the door hinge axis 11. The lining with a rib at the end of the partition is fixed using shoulders 12.

The rib 7, located in the gap between the ends of the closed doors, is constantly surrounded by ambient air to a temperature close to the temperature of the room in which the refrigerator is installed. During operation of the refrigerator, between the rib 7 and the cover 6, part of which is located in the cooled chamber 2, intense heat exchange occurs, as a result of which the pad is heated to a temperature above the dew point, t; е. higher temperature at which condensation occurs, The wider the rib 7, the larger its area, the more intense

heat transfer between the environment and the lining 6 and, therefore, the higher the possibility of heating the lining to a temperature exceeding the dew point. Width

it is advisable to choose the ribs 7 equal to the thickness of the door with a seal, which ensures that the ribs are flush with the front planes of the closed refrigerator doors. T-shaped elements 8 mounted on the end sections of the lining and the longitudinal rib serve as rigid power supports for the axis 11 with a right or left hinge of the refrigerator doors. In this case, the axis 11 is the lower axis

for the upper door and the upper axis for the lower door. In the case of vertical placement of the lining and the longitudinal rib, with the horizontal arrangement of the multi-temperature chambers 2, use the aforementioned

T-shaped elements are not necessary. The pad with the rib is securely held at the end of the septum using the shoulder pads 12.

The proposed design of the cold-seal allows preventing the formation of condensate on the outer end of the thermally insulated partition when the temperature ratio in the temperature chambers is from 0 to -12 ° C. Use of the invention

in combination with an electric heater, the end wall of the partition allows half the power of the heater, to 5.5 kW, with a temperature ratio in different temperature chambers from 0 to -18 ° C.
