1. A cleaning apparatus that removes deposits attached to a structural object to clean the structural object, comprising:
- a jetting unit adapted to jet out a mixture of a substance in gaseous form and the same substance in liquid form or solid form as the former toward the deposits;
a suction unit adapted to suck the jetted mixture and the deposits to which the mixture has been jetted; and
a pump to which said jetting unit and said suction unit are connected,whereina jet port of said jetting unit is surrounded by a suction port of said suction unit and opens in the suction port,said pump comprises a first impeller corresponding to said jetting unit and a second impeller corresponding to said suction unit, andsaid first impeller is disposed coaxially with said second impeller, and blades of said first impeller have inclinations opposite to inclinations of blades of said second impeller.

Abstract
A cleaning apparatus which can efficiently and satisfactorily clean component parts facing narrow spaces. A mixture of a substance in gaseous form and the same substance in liquid form or solid form as the former is jetted out from a jet pipe toward deposits attached to a structural object. The jetted mixture and the deposits to which the mixture has been jetted are sucked into a suction pipe.

6. A cleaning apparatus that removes deposits attached to a structural object to clean the structural object, comprising:
-
a pipe-shaped jetting unit adapted to jet out a mixture of a substance in gaseous form and the same substance in liquid form or solid form as the former toward the deposits; and a pipe-shaped suction unit adapted to suck the jetted mixture and the deposits to which the mixture has been jetted, wherein said pipe-shaped jetting unit further comprises a heated gas jetting unit adapted to jet out a heated gas to the deposits, said pipe-shaped suction unit is adapted to suck the jetted heated gas and the deposits to which the heated gas has been jetted, said pipe-shaped suction unit coaxially accommodates said pipe-shaped jetting unit therein so that a jet port of said pipe-shaped jetting unit is surrounded by a suction port of said pipe-shaped suction unit and opens in the suction port, and the suction port of said pipe-shaped suction unit projects out from the jet port of said pipe-shaped jetting unit. - View Dependent Claims (7, 8, 9)

10. A cleaning apparatus that removes deposits attached to a structural object to clean the structural object, comprising:
-
a pipe-shaped jetting unit adapted to jet out a mixture of a substance in gaseous form and the same substance in liquid form or solid form as the former toward the deposits; and a pipe-shaped suction unit adapted to suck the jetted mixture and the deposits to which the mixture has been jetted, wherein said pipe-shaped jetting unit further comprises a vibration-applied gas jetting unit adapted to apply a vibration to a gas and jet out the gas to the deposits, said pipe-shaped suction unit is adapted to suck the jetted vibration-applied gas and the deposits to which the vibration-applied gas has been jetted, said pipe-shaped suction unit coaxially accommodates said pipe-shaped jetting unit therein so that a jet port of said pipe-shaped jetting unit is surrounded by a suction port of said pipe-shaped suction unit and opens in the suction port, and the suction port of said pipe-shaped suction unit projects out from the jet port of said pipe-shaped jetting unit. - View Dependent Claims (11, 12, 13)
