Definitions

  • This invention relates to quick ice-making units used to shorten the time of making ice in a freezing compartment in current refrigerators and coolers.
  • Ice-obtaining process which is desired to be performed by filling water into an ice container located in the freezing part of the refrigerators, takes usually 30 to 60 minutes depending on the capacity of a refrigerator. It is disadvantageous for the users if this period takes a long time.
  • the system described in the published patent application US 2005076654 has a quick ice-making option.
  • a fan and a compressor are used for enabling the quick ice-making option. Air cooled by an evaporator is transferred into a freezer with the aid of a fan, thereby enabling the ice container to be cooled. Air heated as a result of a heat transfer occurred in the freezer section is vented out and re-cooled, and then it is sent back to the freezer section.
  • homogenous cooling of the ice container cannot be achieved in this system.
  • the system described in the published patent application US 2005072166 has a quick ice-making control mechanism.
  • Water is filled into a semicircular ice container and cooled with the aid of an evaporator.
  • a mixer is used to accelerate the heat exchange between water and cold air within the ice container. Ice formation is achieved by the heat transfer occurring with the aid of the mixer.
  • An ice container is provided with a heater at its outer side to remove ice therefrom.
  • quick ice-making units of this invention can be used.
  • An ice container made of a material having high thermal conductivity is filled with water and placed onto ice-making units of the invention provided with insulated outer surfaces, which are located in the freezing compartment.
  • High-flow cold air fluxes are achieved in the ice-making units of the invention equipped with thermoelectric cooler and/or cold air blower, thereby water in the ice container with high thermal conductivity is solidified quickly.
  • the aim of this invention is to provide ice-making units equipped with thermoelectric cooler and/or cold air blower in order to quickly cool water in the ice container having high thermal conductivity and transform it into ice using forced air circulation in a freezing compartment.
  • Another aim of the invention is to enable these units to be utilized in currently used refrigerators or coolers.
  • the invention is quick ice-making units in a freezing compartment which use a cooling technique based on directing ambient air forcibly by a fan (15) - motor (16) mechanism located in a freezing compartment into the compartment of a cooling element (17) such as an evaporator and cooling this air while passing over the cooling element (17) and re-transferring it into the freezing compartment (1) or the ice chamber (2, 12) from air blowers.
  • a cooling element (17) such as an evaporator
  • a cooling element (17) such as an evaporator
  • FIG. 1 a side view of a quick ice-making unit (A) with thermoelectric cooler is shown.
  • This unit (A) comprises at least one ice chamber (2) with insulated outer surfaces placed into the freezing compartment (1) of a refrigerator, an ice container (3) made of a material with high thermal conductivity which is placed in said chamber (2) and on which one or more water compartments are located, a separator (4) which is slightly above the ice container (3) and dividing the ice chamber (2) into two parts as lower and upper parts, a motor (6) which is located in a housing, at the back side of the ice chamber (2), formed by the side walls of said chamber (2) together with the separator (4), a fan (5) rotated by the motor (6), and a thermoelectric element (7) with multiple heat transfer fins (8, 8') thereon which is placed inside one wall of the ice chamber (2) such that it confronts the fan (5) and provides heat transfer between the compartment (1) and the chamber (2).
  • Ice chamber (2) is also provided with a back passage (10) and a front passage (11) which are located on the front and back sides of the separator (4) and connecting the lower and the upper parts of the separator (4) to each other.
  • Unit (A) can be used in all types of refrigerators, cooling or freezing systems having a mechanism in their freezing compartments (1) wherein air is directed in the compartment (1) onto a cooling element (17) preferably such as an evaporator forcibly with the aid of a fan (15) and a motor (16) which rotates the fan (15), and wherein air cooled on the cooling element (17) is re-transferred into the compartment (1) through blow outlets (19).
  • This unit (A) can also be used in all types of freezing compartments which can be cooled with a different method other than the cooling method including the use of a freezing compartment (1) with evaporator.
  • thermoelectric element (7) Heat transfer fins (8, 8') used in the unit (A) are placed on the thermoelectric element (7) in two groups in such a position that thermoelectric element (7) is located in between and they faces both into the freezing compartment (1) and the ice chamber (2). Said thermoelectric element (7) is a component operated by peltier effect.
  • the heat of cold air within the freezing compartment (1) is transferred to heat transfer fins (8') and the thermoelectric element (7).
  • heat transfer fins (8) facing into the ice chamber (2) are provided to reach a lower temperature than ambient temperature in the compartment (1).
  • Air flow which is obtained by the rotation of the fan (5) located opposite to the heat transfer fins (8) with the aid of a motor (6) is cooled at heat transfer fins (8) and forcibly passed through the back passage (10), and then transferred into the ice container (3) in the lower part of the separator (4).
  • the ice container (3) is made of a material with high thermal conductivity as mentioned previously. Between cold air sent forcibly to the surfaces of the ice container (3) and water which is warmer than this air, a fast heat transfer occurs and the temperature of water decreases due to the high thermal conductivity of the ice container (3).
  • the ice container (3) In order to cool homogenously a number of water compartments located in the ice container (3), there are holes (9) whereon these compartments are connected to each other. Cool air flows around these compartments and reaches the upper side of the ice container (3) and the lower part of the separator (4) from said holes (9), thereby advancing towards the front passage (11). While the temperature of air advancing towards the front passage (11) increases somewhat due to heat transfer between the ice container (3) and water therein, the temperature of water decreases as mentioned earlier.
  • Air advancing into the fan (5) over the separator (4) through the front passage (11) is cooled at thermoelectric element-aided (7) heat transfer fins (8) by re-directing of the fan (4) forcibly and re-transferred into the ice container (3) on the lower part of the separator (4) by passing it through the back passage (10).
  • cooling of air within the freezing compartment (1) is ensured by directing it towards the cooling element (17) forcibly through the motor (16) and the fan (15) mechanism and the cooled air is re-directed into the compartment (1) with the aid of blow outlets (19).
  • forced air circulation provided in this way, water within the ice container (3) is cooled quickly and converted into ice.
  • the walls of the ice chamber (2) are heat-insulated in order to prevent heat transfer between the freezing compartment (1) and the ice chamber (2), except heat transfer fins (8, 8') and thermoelectric element (7).
  • the material of the separator (4) is heat-insulated as the walls of the ice chamber (2) in order to prevent heat transfer between the upper and the lower surfaces of the separator (4).
  • This unit (B) comprises at least one ice chamber (12) with insulated outer surfaces placed into the freezing compartment (1) of a refrigerator, an ice container (13) made of a material with high thermal conductivity which is placed in said chamber (12) and on which one or more water compartments are located, a separator (14) which is slightly above the ice container (13) and dividing the ice chamber (12) into two as lower and upper parts, a front passage (21) which is located on the front side of the ice chamber (12) and connects the lower and the upper parts of the separator (14) to each other, a outlet hole (22) which is located on the back side of the ice chamber (12) and connects the upper part of the separator (14) and the freezing compartment (1) to each other, and at least one inlet hole (20) which is located on the back of the ice chamber (12) and used for the cold air intake, and through which cold air from a cooling element (17) preferably such as an e
