Description

The invention relates to household appliances, in particular to household refrigerators with thermoses for cooked food and can be used in restaurants, buffets, culinary stores.

The prior art household refrigerator (SU No. 1183795, F25D 11/00, 1985), comprising a metal cabinet, a refrigerator and freezer, a refrigeration unit consisting of an electric motor and compressor, an evaporator, an automatic regulator and an electrical circuit.

A disadvantage of the known refrigerator is its lack of a thermos to preserve the warmth of previously cooked food.

The objective of the invention is the creation of an electric refrigerator with a thermos for use (consumption) of food delivered in a thermos in a hot form without heating.

The technical result, which consists in eliminating this drawback in an electric refrigerator containing a metal cabinet, a refrigerator and a freezer, a refrigeration unit consisting of an electric motor and compressor, an evaporator, an automatic temperature regulator and an electrical circuit, is achieved due to the fact that it has a thermos heated for hot food , a hot chamber with electric heating, an electric motor and a compressor enclosed in a sealed enclosure in which freon-12 refrigerant and XB-12 oil with a filter are placed, discharge the tube passing into the condenser tube, the dryer and the suction tube, the hot chamber is located at the level of the refrigeration unit, is separated by a lattice partition and insulated from all sides, including the door, the refrigeration unit is located deep in the niche, and there is a place on the side of the door for cooked food, and the casing of the refrigeration unit is provided with ribs on the outside to enhance heat transfer, near the casing the discharge tube is made in the form of a coil and serves as a tray for cooked food, the hot chamber is equipped with a thermostat to maintain the desired temperature in the chamber.

New is that the electric refrigerator is divided into three parts: freezer, refrigerator and hot chambers. The lower, hot chamber is combined with the space of the refrigeration unit, where the chamber is disconnected and delimited by a steel or cast-iron grid for heat transfer during operation of the refrigeration unit, and the condenser discharge pipe is attached to the finned casing of the unit, and the still-cooled hot pipe is made in the form of a coil (Fig. .3), which is attached to the floor of the hot chamber, outside the refrigeration unit from the partition to the thermally insulated door. The hot chamber and the refrigeration unit are thermally insulated from all sides with the output of the condenser tubes into the surrounding external environment.

The electric refrigerator is illustrated by the drawings:

figure 1 - electric refrigerator;

figure 2 is the same as in figure 1 a section along aa;

figure 3 - scheme of the refrigeration unit.

The electric refrigerator contains three chambers: freezing 1, refrigerating 2, hot 3. The refrigerating unit 4, enclosed in a casing 5, in which the engine and compressor are located, also belongs to the hot chamber. On the casing, to increase the efficiency of heat transfer, ribs 6 are made, contributing to heat transfer to the environment. The hot chamber is divided into two parts by a lattice partition 7, the space 8 for the refrigeration unit and the space 9 is the place for hot food in the container 10. The discharge tube 11 adjacent to the casing of the refrigeration unit is the hottest and a coil 12 is made in this section of the tube, which like the coil in the freezer (not shown in the drawing) is attached to the floor or pan of the hot chamber 3. The electric refrigerator operates as follows.

The temperature regulator automatically makes the refrigeration unit work, which, each time it warms up, delivers the liquefied freon, passing through the condenser, evaporator and dehumidifier, taking away heat, but the previously heated liquefied freon-12 gives off heat through the coil in the hot chamber, through the grating comes from the refrigeration unit. If the temperature in the hot chamber is insufficient, set in the thermostat, equalizes the temperature through the electric circuit.

The technical and economic advantages of the proposed technical solution are as follows:

- saving energy and electricity;

- saving labor costs;

- More time is devoted to intellectual work.
