1. A plastic compressor housing, comprising: at least one thermosetting plastic body for providing an intake pipe, a compressor duct, and an outlet pipe;a thermoplastic at least partially covering said thermosetting plastic body in a hood-like fashion, said thermosetting plastic body being formed as a basic body and said thermoplastic being injection molded on said basic body,wherein at least a first surface of at least a first anchoring element is embodied on at least a first surface of said thermosetting plastic body, and wherein at least a second surface of said first anchoring element is substantially completely covered with said thermoplastic; andwherein at least one end edge of said thermosetting plastic body is covered, at least in regions, by said thermoplastic. 2. The plastic compressor housing of claim 1, wherein said thermosetting plastic body tapers toward the free end in the area of the end edge of said intake pipe and/or outlet pipe, and an extension of said thermoplastic wraps around the end edge. 3. The plastic compressor housing of claim 1, wherein said thermosetting plastic body is covered substantially completely by said thermoplastic at least in the area of said intake pipe and/or of said compressor duct. 4. The plastic compressor housing of claim 1, further comprising at least one fluid guide element connected to said intake pipe, compressor duct, and/or outlet pipe, wherein said fluid guide element is covered, at least in regions, by said thermoplastic, and wherein at least one second anchoring element is embodied on a surface of said fluid guide element, wherein said second anchoring element is covered, at least in regions, by said thermoplastic. 5. The plastic compressor housing of claim 4, wherein the fluid guide element is selected from a group consisting of a fluid filter element, a fluid pipe, and a damping element. 6. The plastic compressor housing of claim 4, wherein at least one anchoring element is embodied on at least a surface of the intake pipe, compressor duct, and/or outlet pipe that is covered, at least in regions, by said thermoplastic. 7. The plastic compressor housing of claim 4, wherein said fluid guide element comprises, at least in regions, a plastic and/or a metal. 8. The plastic compressor housing of claim 1, wherein said thermosetting plastic body comprises at least one attachment area having a step-like, contour form for attaching, at least in regions, at least one additional compressor housing element, wherein at least one surface of said attachment area and/or at least one surface adjacent to said attachment area form said first surface of the thermosetting plastic body. 9. The plastic compressor housing of claim 8, comprising an extension of said thermoplastic that extends beyond said attachment area of said thermosetting plastic body, further comprising at least one sealing lip, wherein the additional compressor housing element is attached between said attachment area of said thermosetting plastic body and said extension of said thermoplastic. 10. The plastic compressor housing of claim 1, comprising at least a first fastening means embodied in said thermosetting plastic body, wherein at least one fastening element is reciprocally connected to said first fastening means, and a second fastening means embodied in said thermoplastic, wherein the at least one fastening element is reciprocally joined to said second fastening means. 11. The plastic compressor housing of claim 10, wherein said plastic compressor housing is fastened to at least one bearing structure by means of said fastening element, wherein the thermoplastic and/or said plastic compressor housing remains fastened to said bearing structure with a reduction in the bonding force between said first fastening means and said fastening element, wherein the reduction in the bonding force results from a change in the strength, consistency and/or substance of said thermosetting plastic body, in the area of said first fastening means. 12. The plastic compressor housing of claim 10, wherein said first fastening means comprises at least a first opening and/or a first fixing device in said thermosetting plastic body and said second fastening means comprises a second opening and/or second fixing device in said thermoplastic, wherein said second opening is aligned with said first opening and said fastening element is inserted into said first opening and into said second opening, at least in regions. 13. The plastic compressor housing of claim 12, wherein said first and/or said second opening and/or said first and/or said second fixing device comprises at least one bore, at least one hole, at least one blind hole, and/or at least one thread, and wherein said fastening element comprises at least one rivet joint, screw connection, clipped connection, or a self-cutting screw. 14. The plastic compressor housing of claim 4, wherein said first anchoring element or said second anchoring element comprises: at least one depression, said depression comprising at least one undercut or at least one groove;at least one elevation, said elevation comprising at least one bar or at least one surface area with an elevated surface roughness; and/orat least one opening in said plastic compressor housing,wherein said depression or said opening are substantially completely filled with said thermoplastic, said bar is substantially contacted on all sides with thermoplastic, and said surface area is substantially completely covered by thermoplastic. 15. The plastic compressor housing of claim 1, further comprising at least a first stiffening device embodied in said thermoplastic and at least a second stiffening device embodied in said thermosetting plastic body. 16. The plastic compressor housing of claim 15, wherein said first stiffening device is formed by covering the second stiffening device with thermoplastic. 17. The plastic compressor housing of claim 15, wherein the first stiffening device and/or the second stiffening device are connected to at least a first compressor housing device and/or at least a second compressor housing device, wherein the first stiffening device and/or the second stiffening device is embodied between the first compressor housing device and the second compressor housing device, wherein the first and second compressor housing devices further comprise said intake pipe, said compressor duct, said outlet pipe, said first anchoring element, said end edge of said thermosetting plastic body, said attachment area, said sealing lip, said first fastening means, said second fastening means, and/or said second anchoring element. 18. The plastic compressor housing of claim 15, wherein a width and/or a height of the first stiffening device and/or the second stiffening device is in the range of 0.2 mm wide by 5 mm high, and wherein at least two first stiffening devices, at least two second stiffening devices, and/or at least one first stiffening device and at least one second stiffening device are spaced approximately 3 to 20 mm from one another. 19.
