Definitions

  • the present invention relates to a refrigerator appliance with pull-out trolley used to refrigerate various types of products, namely bottles.
  • Refrigerators are known on the market, which are used to contain food products and beverage bottles at a controlled temperature.
  • This type of appliances generally comprises a door that is opened by the user in order to collect the products contained in the refrigerated compartment. This operation is not comfortable because the user does not have a place where to position the collected objects; moreover, the opening of the door changes the climatic conditions of the refrigerated compartment.
  • refrigerators provided with a pull-out trolley where the refrigerated objects are disposed.
  • An actuation system that is controlled by the user pulls out the trolley in such a way that the user can collect the objects from the trolley.
  • the refrigeration system of these refrigerators is similar to the one of a domestic refrigerator appliance, and consists in a plate evaporator that is integral with the body of the refrigerated chamber.
  • a traditional refrigeration system is not efficient in combination with a pull-out trolley because it does not distribute cold uniformly.
  • the evaporator is integral with the bottom wall of the refrigerated chamber, the lower portion of the refrigerated chamber is colder than the upper wall.
  • the temperature increases rapidly when the trolley is actuated, and is restored slowly when the trolley is lowered, causing the formation of frost.
  • US4848091 discloses a refrigerated table-bar comprising a body with an upper refrigerated chamber and a lower technical compartment according to the preamble of claim 1.
  • the refrigerated table-bar comprises a refrigerating unit to refrigerate the upper chamber.
  • a partition is mounted in the refrigerated chamber with possibility of sliding vertically.
  • the partition comprises an upper tray and a lower tray in order to support objects to be refrigerated.
  • a table top is integral with the partition in such a way that the refrigerated table-bar can be in a closed position, wherein the table top closes the body on top, and in an open position, wherein the lower tray is basically at the same level as an upper opening of the upper chamber in order for the user to collect objects from the trays.
  • the refrigerated table-bar comprises a vertical lifting system comprising a gas spring disposed inside an external tube disposed centrally in the upper chamber and connected to the partition.
  • the external central tube is moved by an electromagnetic actuator of solenoid type in order to raise and lower the partition.
  • US4848091 is impaired by a drawback, which consists in the fact that the lifting system of the partition is exclusively actuated by the gas spring disposed in the external central tube that is moved by the solenoid actuator. Such a movement is imprecise and subject to jamming because the trays of the partition protrude from the external central tube and the peripheral part of the trays tends to bend.
  • US2200502 discloses a refrigerator comprising a basket that is disposed in a refrigerated chamber and an upper lid that can be opened in order to provide access to the refrigerated chamber.
  • the basket can be moved manually in horizontal direction. Therefore, US2200502 does not disclose any lifting system of the basket.
  • US2093856 discloses a refrigerator appliance that is suitable for being installed in a kitchen table. Such an appliance comprises a refrigerated chamber with a lower compartment and a refrigerated upper compartment that can be accessed from a front opening. A refrigeration system is disposed in the lower level.
  • the refrigerator appliance comprises lifting means to raise the upper compartment.
  • the lifting means are of pantograph type and comprise an electric motor that moves a worm screw that is engaged in a gear.
  • One end of the pantograph mechanism is disposed in eccentric position in the gear. Therefore, a rotation of the gear determines a movement of the pantograph mechanism.
  • One of the levers of the pantograph mechanism is slidingly mounted in a V-shaped horizontal slide. US2093856 is impaired by the fact that its lifting system is complicated, cumbersome and subject to jamming.
  • the purpose of the present invention is to eliminate the drawbacks of the prior art by devising a refrigerator appliance with pull-out trolley that is efficient, capable of guaranteeing uniform refrigeration and provided with a lifting system of the trolley that is not cumbersome, is reliable and is not subject to jamming.
  • Another purpose of the present invention is to provide a refrigerator appliance that is reliable, practical, versatile, and simple to make and install.
