Definitions

  • the invention in question refers to a reciprocating compressor and, more particularly, a reciprocating compressor comprising a hermetically sealed housing having an electrical or electronic circuit protective plate attached to a part of its outer face.
  • the invention in question stands out for presenting a protective plate composed of at least two plate segments, which can be fixed to each other after mounting and closing the hermetically sealed housing of the reciprocating compressor.
  • the invention in question also refers to the process of mounting the hermetically sealed housing of the reciprocating compressor, including the specific steps of conformation of the protective plate of the electric or electronic circuit composed by at least two plate segments.
  • the current state of the art comprises a plurality of reciprocating compressor models and, in particular, a plurality of reciprocating compressor models useful for being applied in refrigeration systems.
  • reciprocating compressors whose mechanisms and functional systems are closed inside a hermetically sealed housing and, in a simultaneous manner, whose mechanisms and functional systems are electrically powered and/or controlled by electrical or electronic circuits arranged outside such hermetically sealed housing. It is important to highlight that reciprocating compressors of this kind are broadly known by a person skilled in the art, as well as being broadly described in specialized technical literature.
  • certain electrical or electronic circuits are arranged outside the hermetically sealed housing of the reciprocating compressors, wherein for said purpose, it is common to be used, posteriorly, at least one protective plate, and, frontally, at least one protective cover, both capable of isolating and/or protecting said circuits from the environment to which the hermetically sealed reciprocating compressor is exposed.
  • FIG. 1 illustrates, in a schematic form, a typical embodiment in accordance to the current state of the art.
  • the conventional protective plates are welded to the hermetically sealed housings of the reciprocating compressors, while the said housings are still open (usually, the hermetically sealed housing of a reciprocating compressor is composed of a base and a lid, which are fixed to each other by welding), that is, it is common that a protective plate is welded to the base of the hermetically sealed housing before the welding between the base and the lid of the said hermetically sealed housing. This fact occurs, mainly, due to the type of welding process used.
  • the protective plate and/or the electric or electronic circuit comprises dimensions (especially the height) greater than the dimensions of the base of the hermetically sealed housing of the reciprocating compressor.
  • the dimensions (especially the height) of the protective plate can represent great limitations to the miniaturization of reciprocating compressors, after all, it becomes extremely complicated (and, sometimes, even impossible) to close the hermetically sealed housing of a reciprocating compressor, whose the protective plate has larger dimensions than the dimensions of the base of the hermetically sealed housing.
  • the JP 2013024067 document describes and illustrates a compressor whose protective plate has regions perpendicularly folded in relation to the general orientation of the hermetically sealed housing base of the compressor. As a result, a free space is reached between the upper end of the protective plate and the upper end of the hermetically sealed housing, which will allow the common welding between the base and the lid of the hermetically sealed housing of the reciprocating compressor.
  • the KR 200963414 document describes and illustrates a compressor whose protective plate is mounted near to the base of the hermetically sealed housing by means of welded mounting guides, which are individually fixed to the base of the hermetically sealed housing.
  • the said protective plate can be subsequently linked to its mounting guides, either with the opened hermetically sealed housing (unbounded base and lid) or with the hermetically sealed housing (base and lid welded).
  • a reciprocating compressor comprising a hermetically sealed housing whose the electrical or electronic circuit protective plate does not represent, regardless of the dimensions of the hermetically sealed housing, limitations to the closing process of the said hermetically sealed housing, that is, limitations to the welding of the housing lid at the housing base.
  • the dimensions of the electric or electronic circuit are not guided and/or stagnated by the dimensions of the hermetically sealed housing of the reciprocating compressor.
  • the reciprocating compressor now disclosed, which, in general terms, comprises a compression mechanism and a compression mechanism-driven system, a hermetically sealed housing conformed by a lid and a base which is liable to be fixed to each other and at least one protective plate for at least one electrical or electronic circuit.
  • the said protective plate is conformed by at least one first plate segment and at least one second plate segment, wherein the said first plate segment is definitively fixed to a part of the outer face of the base of the hermetically sealed housing by fixing means and wherein the said second plate segment being fixed to the said first plate segment by fixing means.
  • the fixing means used for fixation between the first plate segment and the outer face of the hermetically sealed housing base comprises loose points made between the first plate segment and parts of the outer face of the hermetically sealed housing base.
  • the fixing means between the second plate segment and the first plate segment comprise definitive or selective fixing means.
  • At least one mounting guide between the first plate segment and the second plate segment of the said protective plate is further foreseen.
  • the process of mounting the hermetically sealed housing of the reciprocating compressor includes, minimally, a first step of fixing the first plate segment on the base of the compressor housing, a second step of fixing the lid on the base so as to conform the hermetically sealed housing and a third and final step of fixing the second plate segment on the first plate segment.
  • the illustrated electric or electronic circuit comprises a frequency inverter circuit through which it is possible to control the rotation speed of the electric engine (not illustrated) that triggers the compression mechanism (not illustrated) of the reciprocating compressor.
  • the scope of the invention in question is not limited solely to the frequency inverter circuit, and it can cover all and any electrical or electronic circuit used to lead, control, monitor or trigger the compression mechanism (not illustrated, but essentially composed by the assembly formed by the cylinder-block, piston and head) or the triggering system of compression mechanism (not illustrated, but essentially composed of an electric engine).
  • the reciprocating compressor now treated comprises a hermetically sealed housing 1 conformed by a lid 11 and a base 12, both capable of fixing each other by the usual and known means (welding, for example).
  • a hermetically sealed housing 1 conformed by a lid 11 and a base 12, both capable of fixing each other by the usual and known means (welding, for example).
  • the reciprocating compressor further comprises a protective plate 2 and a protective cover (not illustrated) for an electrical or electronic circuit (not illustrated).
  • the protective plate 2 is conformed by at least one first plate segment 21 and a second plate segment 22.
  • the other plate segments could exist and still be part of the protective plate 2 according to the invention in question.
  • the plate segments 21 and 22 are made of metallic blade, by already known industrial processes.
  • first plate segment 21 is fixed, in a definitively manner, to a part of the outer face of the base 12 of the hermetically sealed housing 1 by traditional fixing means (not particularly illustrated) and the second plate segment 22 is fixed to the said first plate segment 21 by fixing means 3.
  • the traditional fixing means (not particularly illustrated), which are responsible for the definitive fixation between the first plate segment 21 and the part of the outer face of the base 12 of the hermetically sealed housing 1 (part that is near to the hermetic end 4 ), comprise conventional means, such as, for example, welding points.
  • the fixing means 3 responsible for fixation between plate segments 21 and 22, they are more versatile, which may or may not be definitive or selective (that is, removable, detachable, and similar concepts), such as, for example, union by screwing, union by welding, union by rivet, union by fitting, union by glue, among others.
  • mounting guides 5 between the first plate segment 21 and the second plate segment 22 are also foreseen - in an optional manner - mounting guides 5 between the first plate segment 21 and the second plate segment 22.
  • these mounting guides comprise similar rails or equivalent structures.
  • the invention in question solves the problem of the miniaturization of the reciprocating compressors, after all, the fact that the protective plate 2 is composed of plate segments 21 and 22 allows to increase the size of the protective plate 2 without being observed problems or limitations relating to the closure of hermetically sealed housing 1.
  • the invention in question allows frequency inverter circuits to be coupled in reciprocating compressors extremely smaller.
  • the mounting and fixing of the components especially the mounting and fixing of the hermetically sealed housing 1 formed by lid 11 and base 12 and the protective plate 2 formed by the first plate segment 21 and the second plate segment 22 comprise the following order:
