Definitions

  • the present invention relates to an airtight compressor provided with an evaporation tray for condensation water, utilized particularly in household refrigerators and freezers.
  • This type of compressor is currently provided with a tray mounted above its upwardly open cap and utilized for collecting the amount of water obtained from the thawing of the frost or ice within the refrigerator in which the compressor is installed.
  • an efficient, safe and automatic solution consists in collecting the water collected within the refrigerator and carrying it outside by means of expedient pipes, and discharging it in the tray that, due to its position, is constantly heated by the compressor cap in operation and therefore in its turn heats the water contained therein thus making it evaporate.
  • trays have been disclosed whose inside is formed substantially as a half-barrel in such a way that it is possible to insert the tray above the compressor head with a single horizontal movement, which is extremely advantageous considering that the compressor is normally housed in a space as small as possible to increase the useful volume of the refrigerating space.
  • a spring locking mechanism between the components, constituted by a first tongued coupling element fixed, usually welded, on the head of the compressor housing and a second spring fixing element for the coupling element, the second element being formed integrally with the material from which the tray is made.
  • the invention substantially consists in eliminating the previous fixing device and utilizing two of the pipes that issue from the compressor and are used for discharging, for returning and for feeding the refrigerating gas in the refrigerator circuit, as a support for expedient engagement elements disposed on the tray.
  • tray 1 With reference to the figures one can see tray 1, compressor 2 and the profile of side 3 that has nonlowered edge 4 utilized to make the tray slide horizontally on the compressor head.
  • the latter is provided with pipes 5, 6, 7 for circulating the refrigerator fluid, the pipes issuing from positions situated “at the front” (from the point of view of the operator who must work there) and laterally from the body of the compressor housing, and being inclined upward.
  • the tray is stabilized with respect to the compressor head by the application of at least two lengthening pieces, first flexible lengthening piece 8 having end portion 9 bent into a curl.
  • the diameter of the curl, the fact that it is made of flexible material, the position, orientation and general arrangement and dimension of the lengthening piece are such that when the tray is applied to the compressor cap the engagement operation of the curl on pipe 5 corresponding to it in position is immediate, elementary and devoid of any problem since the coupling elements are in full view and, as mentioned, lengthening piece 8 is flexible.
  • Lengthening piece 8 is preferably formed integrally by the mold for forming the tray.
  • second lengthening piece 10 As far as second lengthening piece 10 is concerned, it can be realized in quite similar ways to be applied to second pipe 7 of the compressor, so that further explanation is unnecessary.
  • pipe 7 to which this lengthening piece is applied is the discharge pipe, i.e. a metal pipe that can heat to high temperature during operation
  • the lengthening piece cannot be made of plastic material that softens with the temperature of the pipe to which it is applied, and it is therefore necessary for its material to be resistant and flexible at high temperatures, like special types of plastic.
  • a useful improvement consists in realizing a flexible metal foil disposed so as to be easily engaged against hot pipe 7.
  • the expert in the field is readily able to plan the position, the orientation and the form of this foil so that it can be easily engaged with the corresponding pipe so as to strengthen the stabilization of the tray on the head of the compressor housing.
  • a thin metal foil involves a constructional problem: since it cannot be formed integrally with the tray it is necessary to apply it thereto by a subsequent operation, which can be done by forming, preferably molding, hollow 12 in an expedient position on a side of the tray and inserting an end of foil 10 in the hollow.
  • a useful improvement therefore consists in realizing hollow 12 with increased dimensions and artificially increasing the thickness of foil 10 by bending its end to be inserted with at least one reentrant curve 13. This artificially increases the dimension required for housing the foil utilizing the forced interference between curves 13 and the inside walls of the hollow and finally permits a safe and easy locking of the foil on the tray, without any further aid.
