Description

    A COOLING DEVICE COMPRISING A DEFROST HEATER
  • The present invention relates to a cooling device comprising at least one compartment wherein the products to be cooled are placed, an evaporator that provides the cooling of the compartment by evaporating the refrigerant fluid and a defrost heater which enables the ice accumulated on the evaporator surface to be heated and melted during a defrost cycle.
  • The users generally keep the door of the compartments open for a long time in order to place the products they bought into the refrigerator. During this time period, the moisture entering the compartment together with the hot air in the outer environment freezes and causes formation of ice on the cold surface of the evaporator that provides the cooling of the compartment. Furthermore, the moisture in the products also freezes on the cold surface of the evaporator and causes formation of ice. The ice forming on the surface of the evaporator leads to heat insulation effect and causes the evaporator not to cool the compartment sufficiently and the electricity consumption of the cooling device to increase in the following refrigeration cycles.
  • In order to solve this problem, the producers of white goods have designed defrost heaters that allow the ice formed on evaporators to be melted by means of a defrost cycle and the cooling devices comprising the said defrost heaters.
  • In the state of the art Chinese Utility Model Application No. CN20102222083U, a cooling device is explained which comprises a defrost heater that enables the ice formed on an evaporator to be melted by means of a special defrost cycle.
  • In this defrost heater, the heater electric cable placed around the evaporator tube passes through a metal tube. Thus, the risk of electric shock and fire increases.
  • The aim of the present invention is the realization of a cooling device comprising a defrost heater that does not allow electric shock and fire.
  • The cooling device realized in order to attain the aim of the present invention and explicated in the attached claims comprises a defrost heater having a metal tube, an electric cable passing through the metal tube, electrically insulated from the metal tube and enabling the metal tube to be heated, and one gasket placed on each of the ends of the metal tube and that prevents the electric cable from contacting the end of the metal tube. Thus, if the electric cable moves due to a mechanical force, the electric cable is prevented from rubbing against the end of the metal tube and being cut. Thus, the risk of electric leakage and fire is also prevented.
  • In an embodiment of the present invention, the gasket has a body configured as a tube, through which the electric cable passes and a flange formed on one end of the body thereof and that is seated on the end of the metal tube. Thus, the gasket is enabled to entirely cover the end of the metal tube and to be safely seated on the end of the metal tube.
  • In an embodiment of the present invention, both ends of the metal tube are expanded. Thus, the gasket is enabled to be easily placed between the metal tube and the electric cable and to safely protect the electric cable.
  • In an embodiment of the present invention, the inner diameter of the tube-shaped body of the gasket is equal to the inner diameter of the metal tube. Furthermore, the outer diameter of the flange of the gasket is larger than the outer diameter of the metal tube. Thus, the ends of the flange are enabled to be easily grasped from the outside. Additionally, the electric cable is thus enabled to evenly pass through the metal tube and the gasket. Thus, the defrost heater is enabled to occupy less space.
  • In an embodiment of the present invention, the portion of the metal tube between the expanded end and the unexpanded end thereof is configured as an inclined step. Thus, only the end portions of the metal tube are enabled to be wider.
  • In an embodiment of the present invention, the portion of the tube-shaped body of the gasket placed inside the metal tube is seated on the portion of the metal tube configured as an inclined step from the inner side. Thus, the gasket is enabled to be safely placed on the expanded end of the metal tube.
  • In an embodiment of the present invention, a flexible coating enabling the metal tube and the gasket to be pressed towards each other and the inner side of the metal tube to be insulated from the outer side thereof is placed around the portion of the metal tube configured as an inclined step so as to enclose both the gasket and the end of the metal tube. Thus, the coating is prevented from moving or sliding back and forth. Additionally, the gasket is thus prevented from dislodging.
  • By means of the present invention, a cooling device comprising a defrost heater that does not allow electric shock and fire is realized.
  • A model embodiment relating to the defrost heater realized in order to attain the aim of the present invention is illustrated in the attached figure, where:
  • Figure 1 – is a schematic view of the defrost heater in an embodiment of the present invention.
