Definitions

  • This invention relates to a type of refrigerator and the method of manufacturing the door for the refrigerator, moreover, it is invention with respect to a type of refrigerator suitable for both domestic and commercial use, and the method of manufacturing the door for this refrigerator.
  • the door of a refrigerator is an important element in the acceptance of a refrigerator. Due to the special quality of glass, refrigerators with a glass plate as front plate are currently on the market.
  • the glass plate is mounted in a concave groove extending longitudinally upwards from the side frame of the door. The two transverse edges of the glass plate are placed separately in the corresponding concave channel and in this way the glass plate is attached to the other parts of the door in one.
  • this kind of door for the refrigerator has shortcomings as follows: the glass plate is covered at least at two side edges by the side wall of the concave groove of the side frame, so that the side wall of the concave groove is inevitably exposed on the show side of the door. Therefore, the show side of the door is not continuous, but there is a dividing line between the glass plate and the side frame.
  • this type of structure is unfavorable for assembly.
  • the glass plate if the glass plate is reinstalled after the two side frames of the door have been fixed, the glass plate must be slid in the predetermined direction between the two side frames, so that this type of assembly requires a fairly high and moreover required clearance between the glass plate and the Both side frames needed so that the glass plate can be inserted.
  • the two sides of the glass plate are simultaneously connected to the front and rear frame, so that under these conditions the glass plate is also involved in the foaming process.
  • the glass plate can be scratched, so that the manufacturer must take measures to prevent the glass plate from being scratched at the outer edge.
  • this invention aims to provide an applicable manufacturing which may also serve to improve the external appearance of the refrigerator.
  • this invention aims to provide a method of manufacturing a door intended for a refrigerator.
  • the manufacture of said refrigerator comprises a utility space and at least one door for opening and closing said utility space, said door comprising a door body and a front panel connected thereto, the front of said door being at least partially formed by said front panel, among others said door main body comprises a first wall forming the rear of said door and having a second wall at a predetermined distance, and a heat insulating layer received between the first and second walls, characterized in that the door further comprises an adhesive device which is located between said door main body and said front panel, and said front panel is adhered to said door body by means of said adhesive device.
  • the front panel can be glued by means of the adhesive device on the front of the door main part, the establishment of a concave groove on the outer edge for attachment of the front panel is unnecessary. On the one hand, this accelerates the assembly of the door and front panel and door main body are tighter and tighter together, on the other hand, it is expected that the corresponding edge of the front panel is completely exposed, thereby the external appearance of the refrigerator thanks to continuous side of the door will be more appealing. Further, this invention of a refrigerator offers the following possibilities: the front panel is not involved in the foaming operation of the door, so that the door can be mounted on the door main body after fully foaming. This not only prevents the front panel from being scratched during the foaming process, but also provides an advantage for planning the foaming process.
  • An optimal implementation example according to this invention is that said adhesive device comprises an adhesive tape extending said adhesive tape along the transverse edge of said front plate and / or the longitudinal edge.
  • a particularly optimal implementation example according to this invention is that the said adhesive strip is mounted along the transverse edge of said front plate and along the longitudinal edge so as to form a frame in the form of a closed ring.
  • transverse edge and / or the longitudinal edge of said front panel form part of the face of said door.
  • Another optimal implementation example according to this invention is that said second wall is formed by an integrated thin plate.
  • said door body comprises an edge cover of the door, said edge cover of the door forms the side paneling of the outside of said door and is curved from the front end of said side panel and parallel with the edge strip of the inside of the door said front panel, said edge strip forms a part of said second wall.
  • said second wall forms the door leaf of the main part of said second wall, said edge strip lying on one side of said door leaf.
  • said door leaf and the direction of said marginal strip lie on the same plane with the outer surface of said front plate.
  • An optimal implementation example according to this invention is that said edge strip and said door leaf have different thicknesses, said door leaf forming a step on which said edge strip rests.
  • An optimal implementation example according to this invention is that said edge strip has an adhesive device towards one side of said front plate.
  • the direction of said second wall and the outside of said front panel extend on one level.
  • the second wall is made of metal.
  • the refrigerator of this invention uses as a special feature a glass door as a front panel.
  • this invention relates to the method of manufacturing a door of a type of refrigerator, comprising:
  • door main part said door main part comprising the first wall which forms the rear side of said door, a second wall at a fixed distance from the first said wall and a heat insulating layer between said first and second wall; b) a gluing device mounted on the outside of said door main body; c) front panel; d) the front panel pressed onto the door main body, said front panel forms at least part of the outside of said door.
