Method and apparatus for cleaning a pipe system provided for the operation of baths
First Claim
1. A method of cleaning a pipe system having a plurality of conduits in baths comprising flushing said pipe system by passing flushing water from a supply system to the pipe system in a plurality of stages such that flushing water form the supply system is passed in each flushing stage to one conduit or one group of conduits while the supply of flushing water to the other conduits in the pipe system is closed so that the pressure of the flushing water in the conduit or group of conduits being flushed in each flushing stage is higher than the pressure of the flushing water would be if all conduits of the pipe system were flushed simultaneously.

Abstract
The present invention relates to a method of cleaning a pipe system (3) in baths, preferably bath tubs, through which pipe system water and/or air is led into the bath-water (6) of the bath (1) to produce water currents and/or water/air currents (4) and/or air bubbles (5) therein. For effective cleaning, the pipe system (3) is flushed with pure water (31) after a bath has been taken before impurities in said pipe system have/had time to dry. A suitable apparatus for carrying out said method comprises a sensor (49) which is adapted to sense when bathing in the bath (1) has been concluded and to deliver when the bathing has been concluded a signal to a time lag relay (34) which is adapted to open a valve (33) for supply of flushing water (31) to a flushing device (30) for flushing of the pipe system (3) a certain time after the time lag relay (34) has received said signal from the sensor (49).

- 14. An apparatus for cleaning a pipe system for baths having a plurality of conduits comprising a sensor for sensing when bathing in the bath is concluded and generating a signal when bathing is concluded, a time lag relay which receives the signal generated by the sensor and opens a valve for supplying flushing water, and a flushing device for receiving the supply of flushing water and flushing the pipe system a predetermined time after the time lay relay has received the signal from the sensor, said predetermined time being selected so that the flushing of the pipe system occurs before impurities in the pipe system have time to dry therein.
