Description

1

The invention relates to household refrigerators, namely, the construction of a condensed and melt water collection and disposal device in product storage chambers. The refrigerator is equipped with a product storage compartment and a refrigeration unit consisting of a compressor, a condenser, a refrigerant evaporator (s), a control and signaling device, and a dewatering device. In the refrigerator product storage chamber, the water contained in or stored in the refrigerant is condensed and / or precipitated by the refrigerant evaporator. The back wall of the product storage cabinet is equipped with a refrigerant evaporator, so this wall is constantly damp, dripping and condensed water vapor droplets, hereinafter referred to as "melt water". During the breaks in the refrigerator compressor, more melt water is released. The dissolution water enters the water drain hole and the duct (tube) flows into the bath from which it is removed by evaporation. The dissolution water is evaporated in various ways, using either the heat of the compressor or the condenser, or the electric heater or a combination thereof, or by blowing the fan in the air. The rate of evaporation of the dissolving water depends on the efficiency of the heating source, the surface area of the evaporation and the efficiency of the vapor removal.

There is known "Fridge Water Evaporator" (TR9902544 (A2) F25D) in which the bath is attached to the rear wall of the refrigerator casing above the compressor so that it does not touch its top. The disadvantage is a small water evaporation surface, low air circulation.

There is known "Refrigerator with soluble water evaporation tank" (KR2000141255 (Y1); F25D21 / 00) in which the evaporation tank is attached to the refrigerator body above the compressor. The bottom geometry of the evaporation tank corresponds to the geometry of the compressor. There are 3 to 8 air convection channels in the central part of the evaporation tank. The disadvantage of this evaporation tank is its complex design, the small surface of water evaporation.

There is a known "Refrigerator with evaporation bath" (EP1700069 B1; F25D21 / 14) in which the evaporation bath is attached to the refrigerator body above the compressor. The bath is divided into 4 sections. The inner section contains a maze consisting of vertical and horizontal partitions. The dissolving water from the side section enters the inner section 2

LT 6241 B, its surplus flows into the other two side sections. The water is evaporated by the heat of the refrigerator compressor, which heats the bottom of the bath and is spread through the air convection channel in the inner section of the bath. The disadvantage of this evaporation bath is that its construction is complicated.

The object of the patented invention is to improve the evaporation of the melt water and to reduce the construction by increasing the surface area of the evaporated melt water and ensuring the self-convection of the warm air generated by the compressor.

A patented refrigerator comprising a product storage chamber (1) with a refrigerant evaporator (2) located behind the rear wall of the product storage chamber; a melt water removal system consisting of a water collection tray (3a), a drainage channel (3b); water drainage duct (3c), compressor niche (4), compressor (5), capacitor (6). The upper part of the compressor recess (4) over the compressor (5) has one or two melting water collecting tubs (7, 8) protruding from 10 to 70 mm from the rear wall plane of the refrigerator body and secured to the refrigerator body by at least 2 fastening elements ( 9). The baths (7, 8) have one or two hot air convection channels (10). The essence of this design solution is that by using one or two baths, the melting water is spread over a larger area and the flow of warm air from the convection channel improves the evaporation of the water. In the refrigerator, the bottom of both melting water collectors (7, 8) is flat. The essence of this construction solution is that there are no water zones in place and the flat bottom facilitates the production, installation and cleaning of two melting water baths. In the refrigerator, the convection channel (s) (10) of the melt water collection bath is 5 to 15 mm higher than the side walls of the bath (7, 8), its rear wall (10a) is inclined at an angle of 15-25 ° to the outside of the compressor recess, the lower part of the convection channel. the radius (R) of the roundings (10b) is 50 - 150 mm. The channel has a heat accumulating pocket (10c).

The convection ducts (10) are higher than the side walls so that the melt water does not enter the compressor and the electrical installation. Tub end 3

The wall (10a) of wall B (10a) is angled to the outside of the compressor niche for circulation of water vapor-saturated air to the outside of the niche. The lower part of the bath (10b) is made to allow the warm air from the compressor (5) to enter the convection channel (10) more easily. The air pocket (s) (10c) is designed to accumulate heat and improve convection. The top of the refrigerator compressor niche (4) has one melting water collector (7). This design solution is designed for small capacity refrigerators. In the upper part of the refrigerator compressor niche (4), there are two overhead water pickup baths (7, 8). This design solution is designed for high-capacity or often-open refrigerators. The upper bath (8) in the refrigerator compartment recess (4) has an opening (8a) for transferring part of the melt water to the lower bath (7). This construction solution makes it possible to double the surface of the evaporated water. Refrigerated water collecting tubs are attached to the refrigerator casing so that there are gaps (11) for the outlet of water-saturated air. This construction solution ensures circulation of water vapor-saturated air. The refrigeration compressor niche (4) has a shield (12). This construction solution directs more warm air to convection channels (10).
