Definitions

  • the present invention relates to a cooling device comprising an insulation material that is provided to be distributed homogeneously in the insulation volume.
  • an insulation material is filled between the inner and outer walls of the body in order to provide heat insulation between the inner volume and the outer environment. Due to its chemical structure, the insulation material, that is preferably polyurethane, expands and solidifies once it is filled into the body of the cooling device. During this solidification, gaps occur in the insulation material. At the ceiling that is the section the insulation material reaches last, these gaps occur more frequently and cause the sheet metal of the cooling device to collapse towards the section with gaps. These collapses are considered as malfunction by the user and this situation both increases maintenance costs and also distorts the quality perception of the user.
  • the insulation material that is preferably polyurethane
  • quick-solidifying polyurethane is used as the insulation material in order to speed up the body-insulation process and this causes an increase in the number of the gaps.
  • slow-solidifying polyurethane is used in order to prevent collapses on the surface of the body, the production slows down and efficiency decreases.
  • a cooling device wherein the insulation material is provided to be homogeneously distributed by means of the plates placed to the inner side of the inner wall of the body, contacting the insulation material.
  • a solidified epoxy layer and an intermediary resin layer are disposed between the inner wall and the insulation material.
  • a heat insulation wall is described, wherein the top is left open, and after the insulation material is filled therein and pressed by means of a pressing means, the top is closed.
  • the heat insulation wall is the refrigerator door.
  • the aim of the present invention is the realization of a cooling device wherein the gaps in the insulation material filled into the insulation volume are eliminated.
  • the cooling device realized in order to attain the aim of the present invention, is defined in independent claim 1 and dependent claims 2-9.
  • this device comprises a body having an insulation volume disposed between its inner wall and outer wall and wherein the insulation material is filled, and a regulating member that is placed in at least some portion of the insulation volume and provides the insulation material to be homogeneously distributed at that section.
  • the regulating member is web-shaped, and the insulation material is preferably polyurethane.
  • the insulation material filled into the insulation volume through an opening arranged on the outer wall splits into smaller pieces by passing through the holes on the regulating member and thus the number of air gaps occurring during the solidification of the insulation material is decreased.
  • the regulating member is placed to the inner side of the inner wall, contacting the insulation material.
  • formation of collapses on the outer surfaces of the inner wall facing the inner volume of the cooling device, is prevented.
  • the regulating member extends along the surface it is covered on, almost parallel to the inner wall and the outer wall.
  • the regulating member is net-shaped.
  • the regulating member can be easily shaped and is formed in compliance with the structure of the wall where it will be placed.
  • the regulating member can be stored in rolls, can be shaped and used according to the geometry of the section where it will be used. Thus, storing costs are decreased. Moreover, since it is not needed to use different molds for different sections of the body, saving in mold costs is provided.
  • the regulating member is placed to the ceiling.
  • the insulation material that starts solidifying before reaching the ceiling is provided to flow in small pieces upon reaching the ceiling and big gaps that start being formed break into pieces.
  • the frequently-encountered problem of the collapsing of the ceiling is prevented.
  • the regulating member is placed into an intermediary wall that separates the body into compartments.
  • the regulating member is placed into a door providing access into the body.
  • the regulating member is placed between the inner wall and the outer wall and provides the insulation material to be homogeneously distributed inside the door, thus providing the surface of the door to be smooth.
  • two regulating members are placed at intervals between the inner wall and the outer wall so as to be parallel to each other.
  • One of the regulating members is closer to the inner wall, and the other to the outer wall.
  • the holes on the regulating member that is closer to the inner wall are smaller than the holes on the regulating member that is closer to the outer wall.
  • the cooling device (1) comprises a body (2) having an inner wall (3), an outer wall (4), an insulation volume (5) between the inner wall (3) and the outer wall (4) and an insulation material (6) filled into the insulation volume (5) ( Figure 1 , Figure 3 ).
  • an opening (O) is arranged so that the insulation material (6) can be filled into the insulation volume (5).
  • the insulation material (6) that is filled preferably through a single opening (O), reaches almost every section of the insulation volume (5) thanks to its fluid structure.
  • the insulation material (6) that is composed of more than one chemical substance enters into exothermic reaction and solidifies as expanding.
  • the interior volume of the cooling device (1) is provided to be insulated from the outer environment conditions and the durability of the body (2) is increased.
  • the cooling device (1) of the present invention comprises at least one perforated regulating member (7) that is placed into the insulation volume (5) and that prevents the formation of gaps by regulating the flow of the insulation material (6).
  • the insulation material (6) splits into smaller pieces by passing through the holes of the regulating member (7).
  • the number of gaps being formed during the solidification is minimized, and the inner wall (3) is prevented from collapsing towards the outer wall (4) in course of time. This provides the malfunction-occurrence rate to decrease and the quality perception to increase.
  • quick-solidifying insulation material (6) can be used, and this shortens the production time, thereby increasing efficiency.
  • the regulating member (7) is placed on the face of the inner wall (3) facing the insulation volume (5). After the regulating member (7) is fastened onto the inner wall (3) from its edges, the insulation material (6) is filled into the insulation volume (5) through the opening (O) preferably arranged on the outer wall (4). Thus, the insulation material (6) is provided to be solidified at the section just above the inner wall (3) without formation of gaps, and collapses on the inner surface of the cooling device (1) are prevented.
  • the regulating member (7) is placed into the insulation volume (5) so as to be almost parallel to the inner wall (3) and the outer wall (4).
  • the regulating member (7) is net-shaped.
  • the regulating member (7) can be easily shaped depending on the geometry of the surface it will be used.
  • mold and logistic costs are decreased since it is not needed to produce and store regulating members (7) with different shapes for different sections of the body (2).
  • cost advantage and production flexibility are provided ( Figure 2 ).
  • the regulating member (7) is placed at the ceiling (T) section of the inner wall (3), throughout the ceiling (T).
  • the regulating member (7) is fastened to the ceiling (T) section of the inner wall (3) from its edges so as to cover the entire ceiling (T).
  • the insulation material (6) is provided to be homogeneously distributed at the ceiling (T) where the insulation material (6) filled through the opening (O) located at the bottom of the body (2) reaches last, and possible collapses are prevented ( Figure 2 ).
  • the body (2) comprises at least one intermediary wall (8) that divides the body into compartments and the regulating member (7) is placed into the intermediary wall (8).
  • the insulation material (6) is homogeneously distributed over the surfaces of the intermediary wall (8) covered with the regulating member (7) and a smooth appearance is obtained ( Figure 3 ).
  • one regulating member (7) is disposed on each of the faces of the intermediary wall (8) facing both compartments.
  • the body (2) comprises at least one door (9) providing access therein and the regulating member (7) is placed into the door (9).
  • the insulation material (6) is provided to be homogeneously distributed inside the door (9) and outer appearance is improved by preventing the occurrence of collapses on the surface of the door (9) ( Figure 3 ).
  • the cooling device (1) comprises two regulating members (7) that are positioned to be spaced apart from each other.
  • the regulating members (7) are placed into the insulation volume (5) so as to be parallel to each other.
  • polyurethane is preferably used as the insulation material (6).
  • the inner wall (3) contacting the insulation material (6) is prevented from collapsing towards the outer wall (4) due to the gaps that may occur because of the quick-solidification of the insulation material (6).
  • the outer appearance of the cooling device (1) is improved and the number of malfunction-records that may occur due to the collapses on the surface is provided to be decreased.
