DE60009513T2 - HEATING DEVICE AND GRILLE FOR REFRIGERATOR TANK - Google Patents

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

The Invention relates to a refrigerator with a grid that prevents ice from getting around the evaporator of the fresh food and freezer compartment having refrigerator has formed while defrosting in big pieces in the collection container falls and in which these masses preferably by means of heaters be melted.

at known refrigerators is the ice formed on the evaporator over a heater melted and the pieces of ice that had been melted are falling into the water collection store and said masses of ice and snow are made by means of a separate heater melted, which is arranged under the water storage tank. The melting big pieces needed however, a long time and in the meantime, the water drainage channel blocked, which in turn has a negative effect on the operating function of the refrigerator has.

From the FR-A-2 117 851 For example, a refrigerator is known in which the above problem is solved by a device which ensures that no refrigerating cycle is started before the ice present in the water collecting storage is completely melted.

Of the Invention is based on the object to improve the cooling function, that the blockage in the middle compartment and in the store owing Icing is prevented.

The Heater and grid for defrosting the refrigerator, realized, In order to achieve the above object of the present invention, are disclosed in the following drawings. Show it:

Securing device

A perforated grid 2 is used to block the middle compartment and the drainage channel 5 by preventing the snow and ice pieces from entering the water collection store in large quantities while defrosting the evaporator of a two-door "no-ice" refrigerator 4 fall, the freezer and Frischlebensmittelabteile has to these masses by means of the heater 1 to liquefy.

The grid 2 is made of a rectangular and preferably metallic steel sheet. At the bottom of the grid 2 are perforation holes 6 formed, which have a certain distance from each other, and which can be provided in any desired number and shape.

The short edges of the two ends of the grid 2 are extended upwards and at the evaporator 3 appropriate. In addition, the lower part of the evaporator sits 3 the heater 1 at the base of the grid 2 and the heater 1 is by means of the retaining device 7 at the grid 2 is formed in such a way that it attaches to the bottom of the grid 2 is in contact.

The grid 2 is between the evaporator 3 and the water collection store 4 arranged so that the pieces of snow and ice on the evaporator 3 be collected on the grid 2 fall and into the water collection store 4 flow down when they melt. The melting is done by the electric heaters 1 which are switched on during defrosting. In this way, a blockage of the water drainage channel 5 and the middle compartment avoided by preventing the amount of ice directly into the store 4 falls.

Claims (3)

Refrigerator with an evaporator ( 3 ), a water collection storage ( 4 ) and a water drainage channel ( 5 ), characterized by a grid ( 2 ) between the evaporator ( 3 ) and the water collection storage ( 4 ) and the holes ( 6 ), which are formed on its surface, and a blocking of the water drainage channel ( 5 ) and the intermediate area avoids that falling of the frost charge directly into the Storage ( 4 ) is prevented when the around the evaporator ( 3 ) Frost charge of snow and pieces of ice formed around it begins to melt. Refrigerator according to claim 1, characterized in that the short sides at both ends of the grid ( 2 ) extend upwards and on the evaporator ( 3 ) are mounted. Refrigerator according to claim 1 and 2, characterized in that the grid ( 2 ) a heating device ( 1 ) located at the grid ( 2 ) by fasteners ( 7 ) fixed at the base of the grid ( 2 ) are arranged and arranged such that the heating device with the base of the grid ( 2 ) is in contact with the snow and the pieces of ice which have been deposited on the grid during de-icing ( 2 ) have fallen, to melt.
