Definitions

  • the present invention relates to a cooler appliance having a cooling apparatus.
  • Korean patent document no. KR101821097 discloses a cooler appliance having a chamber hermetically sealed from a cooler compartment.
  • EP3006871 discloses a refrigerator having at least one compartment for storing food items placed in closed containers.
  • Korean patent document no. KR100719247 discloses a refrigerator for rapidly cooling a shelf, including an evaporator for generating cold air.
  • JP2001355956 discloses a having a refrigerator having a shelf plate on which foods and the like are placed.
  • the aim of the present invention is to realize rapid cooling of the food products placed in a cooler appliance without allowing bacteria growth.
  • the cooler appliance realized to achieve the aim of the invention and disclosed in the first claim and the dependent claims, comprises a body, and at least one compartment provided in the body.
  • An evaporator provided behind the rear wall of the body, cools the air circulating in the body, thereby reducing the compartment temperature.
  • At least one shelf is provided in the compartment, on which are placed the food products and containers to be cooled.
  • a cooling apparatus is placed on the shelf.
  • the containers containing the food products are placed on the shelf so as to rest on the cooling apparatus.
  • An end of the cooling apparatus is positioned proximate to the evaporator or in contact with the evaporator.
  • the containers contacting the cooling apparatus heat the cooling apparatus by way of conduction and this thermal energy is transmitted to the evaporator. Consequently, the containers containing the food products are cooled rapidly. Rapid cooling enables inhibiting bacteria growth on the food products and provides food safety.
  • the cooling apparatus comprises bars forming a grill-shaped structure by extending parallel to each other.
  • the grill-shaped structure enables increasing the contact surface area between the cooling apparatus and the containers containing the food products. Rapid cooling is thus provided without allowing bacteria growth.
  • the cooling apparatus is plate-shaped.
  • the plate-shaped structure may cover the entire surface of the shelf in accordance with users' needs or may be produced so as to partially cover the shelf surface and in a structure adapted to cool relatively smaller containers.
  • the vertical cross-sectional thickness of the cooling apparatus increases in evaporator direction.
  • the cooling apparatus with a thickness increasing in the direction of the rear wall of the compartment, enables enhancing the heat retention capacity and the capacity of heat transmission to the evaporator. As a result, rapid cooling is provided and bacteria growth is inhibited.
  • the cooling apparatus is detachably placed on the shelf. A user may remove the cooling apparatus from the shelf when he/she does not need to use rapid cooling, thereby increasing the available volume.
  • the slot which forms when the cooling apparatus is removed from the shelf, whose depth increases in evaporator direction acts as an inclined surface to place bottles and cylindrical items therein.
  • the cooling apparatus is placed on the shelf so as to be flush with the shelf surface.
  • the food products to be cooled placed on the shelf are thus enabled to rest on a flat surface.
  • the cooling apparatus comprises a heat transfer surface.
  • the heat transfer surface is placed in contact with the evaporator.
  • the heat transfer surface enables enlarging the surface to which heat is transferred and accelerates heat transfer between the cooling apparatus and the evaporator. By this, a rapid cooling is provided without allowing bacteria growth in the containers placed on the cooling apparatus and containing the food products to be cooled.
  • the cooling apparatus and the heat transfer surface form almost a right angle with each other.
  • the heat transfer surface is placed in the cooling duct between the evaporator and the cooling apparatus, so as to be in contact with the evaporator.
  • the heat transfer surface extends parallel to the cooling duct thanks to forming almost a right angle with the cooling apparatus, and its heat transfer capacity is increased by means of the cold air current passing over it. Rapid cooling is thus provided by the cooling apparatus, inhibiting bacteria growth.
  • the cooling apparatus extends almost parallel to the evaporator. This enables increasing heat transfer with the evaporator. Consequently, the cooling apparatus cools rapidly, avoiding bacteria growth.
  • the invention enables rapidly cooling the containers containing food products with high temperatures, which are removed from ovens, cooking ranges and similar cookers and placed directly in cooler appliances, and enables averting bacteria growth therein likely to threaten user health.
  • the cooler appliance (1) comprises a body (2), at least one compartment (3) provided in the body (2), in which the food products to be cooled are placed, at least one evaporator (4) provided on the rear wall of the body (2), enabling cooling the compartment (3), and at least one shelf (5) provided in the compartment (3), on which the food products to be cooled are placed.
  • the cooler appliance (1) of the invention comprises at least one cooling apparatus (6) provided on the upper surface of the shelf (5) and extending from the shelf (5) towards the evaporator (4), whose one end is in contact with the evaporator (4), on which the containers containing the food products to be cooled are placed, and enabling cooling the containers containing the food products by way of thermal conduction by rapidly conveying the heat thereof towards the evaporator (4).
  • the cooling apparatus (6) is positioned on the shelf (5) and is adapted for the containers containing the food products to be cooled to be placed thereon by a user.
  • the cooling apparatus (6) is in contact with the base of said containers and thereby enables the food products stored in the containers to be rapidly cooled by way of thermal conduction.
  • the cooler appliance (1) comprises a cooling apparatus (6) shaped as a grill consisting of bars extending parallel to each other.
  • the grill-shaped cooling apparatus (6) enables increasing the contact surface between the cooling apparatus (6) and the containers containing food products to be cooled.
  • more than one path is thus formed for transferring the thermal energy to enable thermal conductivity with the evaporator. Rapid cooling is thus enabled, inhibiting bacteria growth on the food products.
  • the cooler appliance (1) comprises a flat plate-shaped cooling apparatus (6).
  • the cooling apparatus (6) having a plate shape forms a flat resting surface for the containers containing the food products to be cooled and facilitates usage.
  • contact surface is increased by using a plate-shaped structure, thereby obtaining rapid cooling and inhibiting bacteria growth on the food products.
  • the cooler appliance (1) comprises a cooling apparatus (6) adapted to be placed in a cut-out formed on the shelf (5) for the apparatus so as to rest almost flush with the shelf (5).
  • the cooler appliance (1) comprises a cooling apparatus (6) whose cross-sectional area thickness increases in evaporator (4) direction.
  • the cross-sectional area of the cooling apparatus (6) increases from the frontal opening of the compartment (3) in which users load the food products to be cooled, towards the evaporator (4) resting behind the compartment (3). Heat is thus effectively transmitted to the evaporator (4), thereby achieving rapid cooling without destabilizing the temperature in the compartment (3) and enhancing the operational efficiency of the cooler appliance (1).
  • bacteria growth is inhibited on the food products cooled rapidly.
  • the cooler appliance (1) comprises a cooling apparatus (6) detachably placed on the shelf (5).
  • the cooling apparatus (6) can be removed from the shelf (5) when not in use, thereby providing additional usage volume on the shelf (5).
  • the cooler appliance (1) comprises a cooling apparatus (6) having at least one heat transfer surface (7) positioned in contact with the evaporator (4).
  • a cooling apparatus (6) having at least one heat transfer surface (7) positioned in contact with the evaporator (4).
  • at least one heat transfer surface (7) is placed on the side of the cooling apparatus (6) positioned in contact with the evaporator (4).
  • the heat of the containers containing the food products to be cooled, placed on the cooling apparatus (6) is thus effectively transferred to the evaporator (4), enabling rapid cooling without allowing bacteria growth on food products.
  • the cooler appliance (1) comprises the heat transfer surface (7) extending so as to form almost a right angle with the plane of the cooling apparatus (6).
  • the heat transfer surface (7) thus extends along the duct provided on the rear wall of the cooler appliance (1), through which cool air passes. Consequently, heat loss of the heat transfer surface (7) increases, enabling rapid cooling of the containers containing the food products to be cooled, placed on the shelf, inhibiting bacteria growth.
  • the cooler appliance (1) comprises a cooling apparatus (6) having the heat transfer surface (7) placed so as to extend in parallel to the evaporator (4) surface.
  • the heat transfer surface (7) extending in parallel to the evaporator (4), increases the heat transfer between the evaporator (4) and the heat transfer surface (7), inhibiting bacteria growth by providing rapid cooling.
  • the cooler appliance (1) comprises at least one sensor (8) detecting the temperature of the food products placed on the cooling apparatus (6), and a control unit (10) activating a motor (9) moving the heat transfer surface (7) closer to or farther from the evaporator (4) according to the temperature value received from the sensor (8).
  • the temperature value received from the sensor (8) is transmitted to the control unit (10). If the transmitted temperature value is higher than a value predetermined by the producer, the control unit (10) activates the motor (9) so as to move the heat transfer surface (7) closer to the evaporator (4).
  • the control unit (10) maintains the position of the heat transfer surface (7) or activates the motor (9) so as to move the heat transfer surface (7) farther from the evaporator (4). By this, the food products placed on the cooling apparatus (6) are prevented from being cooled more than desired. ( Figure 5 )
  • the containers containing the food products to be cooled, placed on the cooling apparatus (6) provided on the shelf (5), are rapidly cooled, thereby enabling their shelf life to be prolonged by preventing bacteria formation, and avoiding conditions likely to threaten users' health.
