Description

    A DEFROST WATER EVAPORATION TRAY, A CONDENSER RETAINER AND A COOLING DEVICE WHEREIN THE SAME ARE USED
  • The present invention relates to an evaporation tray suitable for using in a cooling device, having a container that enables the defrost water forming on the surface of the evaporator to be collected and evaporated, a retainer that can be mounted to the machine-room cabinet of the cooling device, suitable for the mounting of both the evaporation tray and the coil condenser of the cooling device thereon and a cooling device wherein the said evaporation tray and the retainer are used.
  • The producers of white goods designed refrigerators that can evaporate the defrost water by directly heating the defrost water collected in the container or the container wherein the defrost water forming in the refrigerating or freezing compartments is collected in the defrost cycle in order to provide ease of utilization for the users. In these designs, generally refrigerator compressor, condenser tubes or electrically heated cables are used as the heat source. Refrigerators having the design wherein the evaporation tray is placed on the compressor are widely used. However, the usable volume on the compressor of the refrigerators may not be sufficient for evaporating the defrost water.
  • In order to solve this problem, the producers of white goods developed refrigerators having designs that increase evaporation by enabling the tube that leads to the condenser to be passed through the evaporation tray.
  • In the state of the art Korean Patent Application No. KR20120008756, a refrigerator is explained wherein the pipe that leads to the condenser is passed through the evaporation tray. In refrigerators with the said design, holes may occur in the condenser tubes due to the corrosive effect of the water.
  • In order to solve this problem, the producers of white goods developed refrigerators having designs wherein the condenser tube passed through the evaporation tray is isolated or the tube going to the condenser is passed from outside the evaporation tray.
  • In the state of the art European Patent Application No. EP1517106A1, a refrigerator is explained wherein the condenser tube that passes through the evaporation tray is isolated.
  • In the state of the art European Patent Application No. EP2157385A2, a refrigerator is explained wherein the tube leading to the condenser passes from under the evaporation tray.
  • Production of the refrigerators having the said designs requires additional processes and consequently increases the costs.
  • The aim of the present invention is the realization of an evaporation tray that enables the defrost water to be effectively evaporated by using the heat of the condenser and a retainer that can be mounted to the machine-room cabinet of the cooling device, suitable for the mounting of both the evaporation tray and the coil condenser of the cooling device thereon and a cooling device wherein the said evaporation tray and the retainer are used.
  • The evaporation tray, realized in order to attain the aim of the present invention and explicated in the attached claims, is suitable for using in a cooling device and comprises a base the width of which is approximately equal to the width of the coil condenser so as to allow a coil condenser of the cooling device to be placed under the base of the container, and a rear wall the height of which is approximately equal to the height of the coil condenser so as to allow the coil condenser to be adjacently placed under the base of the container, whereon a housing providing the connection of a fan, that cools the coil condenser, and a fan motor is disposed, that extends downwards from the base of the container and that faces the portion of the coil condenser to be cooled by the fan in the situation wherein the evaporation tray is mounted to the cooling device. Thus, the defrost water is enabled to be evaporated by using the heat of the condenser and the temperature of the condenser is enabled to be adjusted at the desired level by using the fan.
  • In an embodiment of the present invention, in the situation wherein the evaporation tray is mounted to the cooling device, bend-shaped recesses and protrusions are formed at the base of the container in order to provide the transfer of heat from the coil condenser to the defrost water collected in the container over a wider surface. Thus, it is possible to effectively use the heat of the condenser and to quickly evaporate the defrost water.
  • In an embodiment of the present invention, in the situation wherein the evaporation tray is mounted to the cooling device, the bend-shaped recesses and protrusions are configured so as to align with the portion wherein the coil condenser is situated, furthermore so as to align with the base portion of the container between the rear wall thereof whereon the fan and the fan motor housing is disposed and the front wall thereof disposed oppositely and also so as to variably elongate upwards and downwards in the vertical direction. Thus, the defrost water is enabled to be collected in the recesses close to the condenser functioning as the heat source and to be subjected to heat over the wide surfaces of the recesses.
  • In an embodiment of the present invention, the bend-shaped recesses and protrusions are configured as channels moving parallel to the rear wall and the front wall of the container. Thus, the heat transferred from the condenser to the defrost water is enabled to be properly dispersed in the channel and the defrost water is enabled to be properly evaporated.
  • In an embodiment of the present invention, in the situation wherein the evaporation tray is mounted to the cooling device, the bend-shaped recesses are disposed at the base of the container so as to allow the condenser tubes disposed at the upper side of the coil condenser to be placed therebetween. Thus, the defrost water is enabled to be evaporated more effectively by using the heat emitted by the portions of the condenser tubes remaining inside the recess.

  • In all the embodiments of the present invention, the evaporation tray (1) is suitable for using in a cooling device and comprises a base (2) the width (in Y-direction) of which is approximately equal to the width of the coil condenser (7) so as to allow a coil condenser (7) of the cooling device to be placed under the base (2) of the container (6) and a rear wall (4) the height of which is approximately equal to the height of the coil condenser (7) so as to allow the coil condenser (7) to be adjacently placed under the base (2) of the container (6), whereon a housing (10) providing the connection of a fan (8) and a fan motor (9) enabling the coil condenser (7) to be cooled is disposed, that extends downwards from the base (2) of the container (6) and faces the portion of the coil condenser (7) to be cooled by the fan (8) in the situation wherein the evaporation tray (1) is mounted to the cooling device (Figure 4 and Figure 5). Thus, the defrost water is enabled to be evaporated by using the heat of the condenser (7) and the temperature of the coil condenser (7) is enabled to be adjusted at the desired level by using the fan (8). Generally, the dimensions of coil condensers (7) can be variable. The width of the evaporation tray (1) of the present invention in Y-direction and the height of the rear wall (4) thereof in Z-direction are determined according to the coil condenser (7) on which the evaporation tray (1) will be placed. Therefore, the dimensions of the evaporation tray (1) are not needed to be given here.
  • In an embodiment of the present invention, in the situation wherein the evaporation tray (1) is mounted to the cooling device, bend-shaped recesses (11) and protrusions (12) are formed at the base (2) of the container (6) in order to provide the transfer of heat from the coil condenser (7) to the defrost water collected in the container (6) over a wider surface (Figure 1). Thus, the heat of the condenser (7) is enabled to be effectively used and the defrost water is enabled to be quickly evaporated.
  • In an embodiment of the present invention, in the situation wherein the evaporation tray (1) is mounted to the cooling device, the bend-shaped recesses (11) and protrusions (12) are configured so as to align with the portion wherein the coil condenser (7) is situated, furthermore so as to align with the base portion of the container (6) between the rear wall (4) and the front wall (3) thereof disposed oppositely and also so as to variably extend upwards and downwards in the vertical direction (Z) (Figure 4). Thus, the defrost water is enabled to be collected in the recesses (11) close to the condenser (7) functioning as the heat source and to be subjected to heat over the wide surfaces of the recesses (11) (Figure 5).
  • In an embodiment of the present invention, the bend-shaped recesses (11) and protrusions (12) are configured as channels moving parallel to the rear wall (4) and the front wall (3) of the container (6) with fixed cross-sections (Figure 1 and Figure 4). Thus, the heat transferred from the coil condenser (7) to the defrost water is enabled to be properly dispersed in the channel and the defrost water is enabled to be properly evaporated.

Thus, the defrost water is enabled to be evaporated more effectively by using the heat emitted by the portions of the condenser tubes (13) remaining inside the recess (11). Since the recesses (11) prevent the air flow generated by the fan (8) from cooling the portions of the condenser (7) remaining inside the recess (11) by shielding, it is possible to transfer more heat to the defrost water. The temperature of the condenser (7) is adjusted to the desired level by the air flow generated by the fan (8) and which acts on the portions of the condenser (7) remaining outside the recesses (11). The recesses (11) that move in the shape of bends and wherein the defrost water can fill are not necessary to be used for the collection of the air heated by the condenser (7) under the evaporation tray (1). In an embodiment of the present invention not shown in the figures, at least one or more than one solid, screen-shaped protrusion is realized under the evaporation tray (1), extending between the condenser tubes (13) in the situation wherein the evaporation tray (1) is mounted to the cooling device.

In the embodiment of the present invention not shown in the figures, solid protrusions produced from a material with high thermal conductivity and that enlarge the surface are provided in the container (6) in order to transfer the heat emitted from the condenser (7) more quickly to the defrost water.
  • In an embodiment of the present invention, the two side walls (5) of the evaporation tray (1) are parallel to each other and connect the rear wall (4) and the front wall (3) to each other, and the space forming therebetween enables the air flow to be guided to the portion of the coil condenser (7) to be cooled by the fan (8) in the situation wherein the evaporation tray (1) is mounted to the cooling device (Figure 3). Thus, the temperature of the condenser (7) is enabled to be effectively adjusted to the desired level by the fan (8) (Figure 4). The length (in the X-direction) of the evaporation tray (1) is preferred to be longer than the length of the coil condenser (7). Thus, the fan (8) is enabled to be safely placed under the evaporation tray (1), between the rear wall (4) and the condenser (7). Generally, the dimensions of fans (8) can be variable. The length of the evaporation tray (1) in X-direction is determined depending on the dimensions of the fan (8) to be used.
