Abstract

A perforated (6) grid (2) is used to avoid the blocking of the intermediate division and the water drainage canal (5) by the snow and ice pieces that fall into the water drainage pool (4) in large masses during the defrosting of the evaporator of a two-door, 'No-Frost' refrigerator having freezer and fresh food compartments and to melt these masses by means of the switched-in heaters (1). The grid (2) is made of a rectangular and preferably metallic sheet iron piece. At the bottom of the grid (2) perforations (6) are arranged with a certain distance from each other and in any desired number and form. Furthermore, the lowest part of the evaporator (3) heater (1) is seated on the grid (2) base and the heater (1) is mounted by means of the detents (7) formed on the grid (2), in such a manner that it will be in contact with the bottom of the grid (2).

Description

A HEATERAND A GRID FORREFRIGERATORDEFROSTING
The present invention is related to a grid that prevents, the frost formed around the evaporator of a refrigerator having fresh food and freezer compartments, from falling in large pieces into the drainage pool during defrosting and to the melting of the said masses by means of heaters.
The frost formed on the evaporator has been melted via a heater and ice pieces that has been melted fall into the water drainage reservoir and the said masses of ice and snow are melted by means of a separate heater placed below the water drainage reservoir. However the melting of big pieces takes a long time and meanwhile the water drainage canal is jammed which in turn has a negative impact on the operational performance of the refrigerator.
The object of the present invention is to improve the cooling performance by preventing the blockage in the intermediate compartment and in the reservoir, due to frosting.
The heater and grid for refrigerator defrosting, realized in order to attain the above object of the present invention are illustrated in the attached drawings, wherein:
Figure 1, is the schematic profile view of the refrigerator; Figure 2, is the view of the evaporator and the grid; Figure 3, is the side view of the grid;
Figure 4, is the top view of the grid;
The components shown in the drawings are enumerated separately as follows:
1. Heater 2. Grid
3. Evaporator
4. Water drainage reservoir
5. Water drainage canal 6. Perforations
7. Detent
A perforated grid (2) is used to avoid the blocking of the intermediate division and the water drainage canal (5) by the snow and ice pieces that fall into the water drainage reservoir (4) in large masses during the defrosting of the evaporator of a two-door, "No-Frost" refrigerator having freezer and fresh food compartments and to dissolve melt these masses by means of the heaters (1).
The grid (2) is made of a rectangular and preferably metallic sheet iron piece. At the bottom of the grid (2), there exist perforations (6) arranged with a certain distance from each other and in any desired number and form.
The short edges on both ends of the grid (2) are extended upwards and mounted on the evaporator (3). Furthermore, the lowest part of the evaporator (3) heater (1) is seated on the grid (2) base and the heater (1) is mounted by means of the detents (7) formed on the grid (2), in such a manner that it will be in contact with the bottom of the grid (2).
The grid (2) is placed between the evaporator (3) and the water drainage reservoir (4), so that the snow and ice pieces accumulated on the evaporator (3) drop onto the said grid (2), and flow down into the water drainage pool (4) as they melt. Melting is provided by the electrical heaters (1) that are switched in during defrosting. In this manner, blocking of the water drainage canal (5) and of the intermediate division is avoided by preventing the frost load from falling directly into the pool (4).

Claims

1. A refrigerator characterized with a grid (2) placed between the evaporator (3) and the water drainage reservoir (4), having perforations (6) formed on its surface, that avoids blocking of the water drainage canal (5) and of the intermediate division, by preventing the frost load from falling directly into the reservoir (4) when the frost load consisting of snow and ice pieces formed around the evaporator (3) start melting.
2. A refrigerator according to Claim 1, characterized with a grid (2), the short sides on both ends of which are extended upwards and mounted on the evaporator (3).
3. A refrigerator according to Claim 1, and 2, characterised with a grid (2), which also includes a heater (1) fixed on the grid (2) by means of the detents
(7) that are present on the grid (2) base, and arranged so that it contacts with the grid (2) base, to provide the melting of the snow and ice pieces that have fallen onto the grid (2) during defrosting.
