<P>PROBLEM TO BE SOLVED: To provide an ozone-type water supply pipe cleaning apparatus and ozone-type water supply pipe cleaning method in which foreign substances are efficiently removed by a reverse jet nozzle by short-time cleaning work and a sanitary state is improved by efficient deodorization and sterilization effects. <P>SOLUTION: During a cleaning operation, ozone-containing water Wf jetting out from a reverse jet nozzle 15 is uniformly sprayed to the inner wall surface 11 of a water supply pipe 6 as a jet stream S. Accordingly, not only sliminess or fur but also foreign substances Fm such as tubercle firmly stuck to the inner wall surface 11 of the water supply pipe 6 in an intra-pipe scale can be efficiently blown away. Accordingly, the inside of the water supply pipe 6 is efficiently deodorized and sterilized as a whole, the sanitary state of the water supply pipe 6 is improved and cleaning work of the water supply pipe 6 is completed in a short period of time, thereby improving working efficiency. <P>COPYRIGHT: (C)2012,JPO&INPIT |
