Definitions

  • the present invention relates to a cooling device comprising a cover whereof the side facing the fresh food compartment is insulated.
  • cooling devices there are at least two compartments, generally one being a fresh food and the other a freezer, which are kept at different temperatures from each other.
  • the fresh food compartment is allocated for storing foods such as fruits and vegetables and the temperature is kept around 5°C.
  • the freezer compartment with a temperature around -18°C, foods such as meat and fish are placed that have to be stored for a longer time.
  • an air channel is provided with air blowing holes arranged thereon, for conveying the air activated by the fan into the fresh food compartment.
  • Thermostats for adjusting the temperatures of the fresh food and freezer compartments and a valve for controlling the air flow by changing the cross section of the air channel are disposed inside the air channel.
  • the valve and the thermostat are situated inside the air channel and safeguarded by a cover. The cover separates the air channel and the fresh food compartment and a knob is placed thereon so that the user can adjust the valve and/or the thermostat from inside the fresh food compartment.
  • the insulation of particularly the cover that houses the damper thermostat is tried to be accomplished by applying styrofoam material on the inner wall.
  • styrofoam material on the inner wall of the damper thermostat cover that having particularly indented surfaces, a desired configuration without any gap therebetween itself and the surface.
  • a gap remains between the styrofoam material and the cover surface, cold air seeps into these gaps. Accordingly, condensation appears on the cover surface, particularly on the side facing the fresh food compartment, since the side of the cover facing the air channel is in contact with cold air and the side facing the fresh food compartment is in contact with relatively hotter air.
  • a heater is disposed in contact with the surface of the cover facing the air channel.
  • disposing styrofoam and heater on the cover increases both labor and costs and also the energy consumption.
  • the aim of the present invention is the realization of a cooling device comprising a cover wherein condensation is prevented on the surface thereof facing the fresh food compartment.
  • the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a cover, fitted over the air channel in the fresh food compartment, the surface thereof facing inside the air channel is entirely clad by polyurethane material, safeguarding the thermostat and the shutter disposed in the air channel, and a knob mounted thereon for controlling the thermostat and/or the shutter.
  • the surface of the cover forming an intermediate surface where the cold and hot air meet, facing inside the air channel, is insulated such that no gap is left therebetween the insulation material and the surface wall.
  • the polyurethane material due to its feature, takes the shape of the mould and hence the shape of the cover by expanding and solidifying inside the mould and adheres to the surface of the cover facing the air channel without any gaps therebetween.
  • the surface of the cover having surfaces forming intermediate surfaces where cold air and hot air meet inside the compartment, safeguarding for example the damper thermostat disposed inside the air channel, is effectively insulated.
  • the use of a heater is not necessary, maintaining savings in cost, labor, and energy.
  • Figure 1 - is the front view of a cooling device.
  • Figure 2 - is the A-A cross sectional view of Figure 1.
  • the cooling device (1) of the present invention comprises a freezer compartment (2) wherein foods to be frozen are placed, a fresh food compartment (3), kept at a higher temperature than the freezer compartment (2), wherein foodstuffs to be cooled are emplaced, at least one evaporator (4) for cooling the air circulated in the compartments (2,3) one or more fans (5) for activating the air cooled by the evaporator (4), an air channel (7) for delivering the air activated by the fan (5) into the fresh food compartment (3), one or more thermostats (10) disposed inside the air channel (7) for regulating the temperatures of the compartments (2, 3), a shutter (9) that controls the air flow by changing the cross section of the air channel (7), a cover (6) that safeguards the shutter (9) and the thermostat (10), fitted over the air channel (7) in the fresh food compartment (3), such that one side faces the air channel (7) and the other side the fresh food compartment (3), and a knob (8) mounted on the cover (6) so that the user can adjust the shutter (9) and/or
  • the formation of condensation on the surface of the cover (6) facing inside of the fresh food compartment (3) and contacting with relatively hotter air is prevented.
  • the polyurethane material adheres on the cover (6), preferably made of plastic, by itself.
  • the use of a heater for preventing condensation is not necessary since the polyurethane material adheres to the cover (6) surface and entirely takes the shape of the surface.
  • mounting the polyurethane material on the surface does not require additional time and labor consumption.
  • the thermostat (10) is a damper thermostat and directly controls the shutter (9) that changes the cross section of the air channel (7).
  • the cover (6) is produced from polyurethane material.
  • the side of the cover (6) facing inside the air channel (7) is made directly from polyurethane material.
  • polyurethane material is poured into the mould and the mould is closed. The polyurethane material taking the shape of the mould and hence the shape of the cover (6) by expanding and solidifying inside the mould is taken out and is mounted over the air channel (7) in the fresh food compartment (3).
  • the outer surface of the polyurethane material taken out of the mould is painted.
  • the surface of the mould is painted in any color desired.
  • polyurethane material is poured into the mould and the mould is closed.
  • the polyurethane material taking the shape of the mould and hence the shape of the cover (6) by expanding and solidifying inside the mould is taken out with the side facing the fresh food compartment (3) painted.
  • the cover (6) that is subsequently mounted on the air channel (7) in the fresh food compartment (3), and having particularly indented surfaces, is insulated without any gaps between the polyurethane material and the cover (6) as a result of cladding the side thereof facing the air channel (7) by polyurethane material. Accordingly, formation of condensation on the cover (6) surface facing the fresh food compartment (3) is prevented. This removes the necessity of heater usage thereby maintaining savings in cost, labor, and energy.
