Definitions

• the present invention relates to a cooling device comprising ice trays that are used in making ice.
• making ice is performed generally by filling water into the ice tray by the user and placing the ice tray in the freezing compartment.
• the cooling and freezing phases that start after water is filled into the ice tray are maintained entirely with the cooling provided by the refrigerator.
• heat is absorbed from water proportionally to the specific heat of water and in the freezing phase, heat is absorbed proportionally to the latent heat.
• the cooling phase of water is generally short but the freezing phase is comparatively longer. This situation makes it hard to make ice in the refrigerator in a short period of time.
• the ice making vessel is composed of an internal vessel and an external vessel, a cold heat storage agent that can store low temperature for a long period of time is disposed between the internal vessel and the external vessel.
• the aim of the present invention is the realization of a refrigerator wherein ice is provided to be made quickly in the ice tray placed in the freezing compartment.
• the refrigerator realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a receptacle whereon the ice tray is placed, having cavities shaped as hollow, closed boxes, and extending inward from the upper wall thereof, wherein the ice cells are seated and surrounding the cell walls from the outside.
• a phase changing material that changes phase at a temperature below zero is provided inside the receptacle so as to contact at least partially the underside of the cavities.
• phase changing material in an embodiment of the present invention, a phase changing material

• the receptacle is
• compartments composed of compartments in each of which a single cavity is disposed and into each of which phase changing material is placed. Channels are provided between the compartments that separate the compartments from each other.
• the compartments are in cubical form or in frustoconical form similar to cell structure.
• the receptacle is like a wide tray with the base area almost as much as the area of the other body shelves used in the refrigerator.
• the phase changing material is placed in the receptacle so as to cover the base partially or entirely.
• the receptacle used in the refrigerator of the present invention provides ice to be obtained quickly in the ice tray by means of the phase changing material placed therein.

• the refrigerator (1 ) comprises one or more freezing compartments (2) and an ice tray (4) placed in the freezing compartment (2) having more than one cell (3) providing ice to be obtained by freezing the water filled therein.
• the refrigerator (1 ) of the present invention comprises a receptacle (6) whereon the ice tray (4) is disposed, having one or more cavities (5) shaped as hollow, closed boxes, wherein the cells (3) are seated and which surrounds all around the surfaces of the cells (3) except the surface wherein water is filled and ice comes out and wherein phase changing material (PCM) that changes phase at a temperature value below zero degree is filled so as to at least partially contact the bottom sides of the cavities (5).
• PCM phase changing material
• the phase changing material (PCM) that changes phase at a temperature value between - 1 to - 20 degrees is filled into the receptacle (6). Since the set temperature of the freezing compartment (2) is around - 18 degrees, the phase changing material (PCM) that changes phase preferably at a temperature value slightly higher than this value, for example at - 17 degrees, is filled into the receptacle (6).
• the receptacle (6) whereon the ice tray (4) is disposed speeds up the freezing phase of water with the aid of the phase changing material (PCM) filled therein and provides ice to be obtained in a short period of time.
• Phase changing material (PCM) that changes phase at a temperature value lower than zero degree whereat water freezes, preferably at a temperature value between - 1 to - 20 0 C is filled into the receptacle (6).
• the phase changing material (PCM) that changes phase at - 17 degrees is used, the phase changing material (PCM) stays in liquid state in environments having a temperature higher than - 17 degrees and stays in solid state in environments having a temperature lower than - 17 degrees.
• phase changing material (PCM) that changes phase at - 17 degrees therein
• PCM phase changing material
• phase changing material (PCM) in the receptacle (6) starts to change phase with the temperature effect of water and quickly absorbs heat from water in the cells (3) by the latent heat absorption energy stored thereby provides the water to freeze in a short period of time.
• the receptacle (6) comprises more than one compartment (7) that bears each cell (3) in the ice tray (4) separately, each one having a single cavity (5) and each one filled with the phase changing material (PCM) and more than one channel (8) that separates the compartments (7) from each other ( Figure 3).
• PCM phase changing material
• compartments (7) are in cubical form ( Figure 4).
• compartments (7) are in frustoconical form ( Figure 5).
• the structure consisting of compartments (7) and channels (8) makes the receptacle (6) flexible and provides the ice tray (4) to be dislodged from the receptacle (6) more easily particularly after the ice formation phase.
• the receptacle (6) is
• phase changing material is filled into the receptacle (6) such that the base thereof is partially or entirely covered ( Figure 6, Figure 7).
• the receptacle (6) provides cooling to continue in the refrigerator (1 ) for a long time period in the case of power outage by means of the latent heat absorption energy stored in the large amount of phase changing material (PCM) contained therein.
• the receptacle (6) used in the refrigerator (1 ) of the present invention provides ice to be obtained quickly in the ice tray (4) disposed thereon by means of the phase changing material (PCM) placed therein.
• the receptacle (6) furthermore conserves the low temperature environment in the refrigerator (1) for a long period of time when the refrigerator (1 ) does not operate due to power outage or another reason by means of the large amount of latent heat absorption energy stored.
