Description

  • The present invention relates to an evaporator assembly for use in a refrigeration appliance, in particular a no-frost domestic refrigerator. The present invention also relates to a process of manufacturing the refrigeration appliance by using the evaporator assembly.
  • The no-frost technology is an effective method of reducing humidity in a refrigeration compartment in order to prevent formation of frost on an inner case of the refrigeration compartment and on the articles stored therein. A refrigeration appliance utilizing the no-frost technology generally includes an air circulation facility along which the air inside the refrigeration compartment is conveyed by means of a fan towards the evaporator and subsequently discharged into the refrigeration compartment. In the no-frost refrigeration appliance the evaporator of the refrigeration circuit is disposed at a location outside the refrigeration compartment usually in a rear partition of the inner case which has an air inlet and an air outlet for the circulation of the air. Thereby, the moisture in the circulated air freezes on the surface of the evaporator as the refrigerant evaporates. During the circulation of the air, heat is also transferred with the circulated air from the articles stored in the refrigerating compartment to the evaporator through convection. As the moisture in the circulated air freezes on the surface of the evaporator, the proper functioning of the evaporator starts degrading. Therefore, the evaporator must be eventually defrosted.
  • In general, the refrigeration compartment must be thermally insulated from an outside in order to improve the refrigeration performance. Therefore, a region between the inner case of the refrigeration compartment and the outer case of the refrigeration appliance is filled with foam material, in particular polyurethane.
  • JPH0849965 (A) discloses a refrigerator which has an evaporator located in a rear partition of the refrigeration compartment. A gap between the inner case of the refrigeration apartment and the outer case of the refrigerator is filled with foam material.
  • EP1154210 discloses a refrigerator with a plate evaporator that is disposed in an air channel behind the rear wall of a refrigeration compartment. The back wall of the air channel has feet for pressing the evaporator against the rear wall of the refrigeration compartment, thus transmitting the thrust which is exerted during formation of the insulation of the refrigerator.
  • WO2012104884 discloses a refrigerator having a panelled structure with a front plate and a rear plate. An evaporator tube may be arranged in said structure in a channel running adjacent to the front plate. Other channels in the structure contain an eutectic material or transport forced circulated air.
  • A problem with the foam material is that during the curing process, the foam material exerts pressure on the inner case and on the outer case such that the plastic elements thereof start deforming. If the inner case is permanently deformed when the foam material is completely cured, it becomes impossible to properly install the evaporator into the partition.
  • In a commonly known technique spacers are utilized to prevent deformation of the plastic elements during the curing process. After the foam is completely cured, the spacers are removed and the evaporator is installed. However, the assembly process of the evaporator becomes more complicated after the gaps have been filled with the foam material. Moreover, a thermal insulation performance degrades when the foam material is damaged during the assembly process of the evaporator.
  • An objective of the present invention is to provide an evaporator assembly and a refrigeration appliance having the same which overcomes the aforementioned drawbacks of the prior art and which enables an easy and a reliable installation of the evaporator. Another objective of the present invention is to provide a process of manufacturing the refrigeration appliance by using the evaporator assembly of the present invention.
  • This objective have been achieved by the evaporator assembly as defined in claim 1, the manufacturing process as defined in claim 9, and the refrigeration appliance as defined in claim 10. Further achievements have been attained by the subject-matters respectively defined in the dependent claims.
  • The evaporator assembly of the present invention has a casing for accommodating an evaporator. The casing has a front cover and a rear cover which are detachably attachable. The front cover forms a portion of an inner case of the refrigeration compartment. The rear cover has on its inner surface a protrusion which firmly abuts against an opposing surface of the front cover. A cross-section and a material of the protrusion is configured to exhibit a sufficient strength to withstand without being deformed, a pressure exerted by a curing foam material which is injected between the outer surface of the rear cover and the outer case during an assembly process. In addition, the protrusion is formed on an inner surface of the rear cover at a position which does not obstruct installation of the evaporator.
  • The present invention also provides a process of manufacturing the refrigeration appliance by using the evaporator assembly. In the manufacturing process of the refrigeration appliance the evaporator is installed into the casing from an open side of the rear cover. Then, the rear cover is attached to the front cover. Subsequently, foam material is injected between the outer surface of the rear cover and the outer case.
  • According to the invention, the protrusion has a mounting portion for detachably attaching the evaporator to the rear cover. With the protrusion having the mounting portion, the evaporator can be secured to the casing and simultaneously protected from possible damages during the foaming process. Thereby, an inner structure of the casing has been simplified. The circulation of air through he casing has been improved.
  • By virtue of the evaporator assembly of the present invention, the evaporator can be installed into the casing without interference with the protrusion which prevents deformation of the cover during the curing of the foam material. The thermal insulation can be formed by foam material in a state where the evaporator has been already installed into the casing. Thereby, the manufacturing process of the refrigeration appliance has been simplified and a high quality thermal insulation has been attained. The casing has been effectively protected from deformations through the curing foam material during the manufacturing process. Thereby, the evaporator has been protected from damages. Thus, the proper installation of the evaporator has been maintained after completion of the foaming process.

  6. The evaporator assembly (1) according to any one of claims 1 to 5, characterized in that the front cover (8) is integrally provided with the inner case (3), wherein the air inlet and the air outlet are formed in to the front cover (8).
  7. The evaporator assembly (1) according to any one of claims 1 to 6, characterized in that the rear cover (9) having a tube inlet (18) and a tube outlet (19) for respectively inserting an incoming tube and an outgoing tube of the evaporator; a cable throughlet (20) for inserting a electrical power transmission cable (21) of an electrical defrost heater (23) attached to the evaporator (7) and a discharge outlet (22) for discharging defrost water.
  8. The evaporator assembly (1) according to claim 7, characterized in that the cable throughlet (20) is formed close to an upper side of the rear cover (9) and the discharge outlet (22) is formed on a lowest side of the rear cover (9).
  9. A process of manufacturing a refrigeration appliance (2) using the evaporator assembly (1) as defined in any one of claims 1 to 8, the manufacturing process comprising the steps of:
    - installing the evaporator (7) into the casing (6),
    - attaching the rear cover (9) to the front cover (8) and
    - injecting foam material between the outer surface (9b) of the rear cover (9) and the outer case (5).
  10. A refrigeration appliance (2), in particular a domestic refrigerator comprising an inner case (3) which forms a refrigeration compartment (4); and an outer case (5) which forms a body of the refrigeration appliance (2), characterized by an evaporator assembly (1) as defined in any one of claims 1 to 8.
  11. The refrigeration appliance (2) according to claim 10, characterized by an evaporator (7) which has a meandering refrigerant conveying tube.
  12. The refrigeration appliance (2) according to claim 11, characterized in that the evaporator (7) is provided with fins.
  13. The refrigeration appliance (2) according to claim 11 or 12, characterized in that the evaporator (7) is provided with an electrical defrost heater (23).
