Method of, and apparatus for, introducing a cleaning agent and/or disinfectant into sanitary facilities
First Claim
1. A method of introducing a cleaning, disinfecting and/or deodorizing liquid into a sanitary facility, comprising the steps of:
- monitoring the pressure of a flushing water in a flush cycle of the sanitary facility to determine a time duration of the flushing cycle and obtain a pressure profile for the flushing cycle;
determining a desired time and duration for the introduction of the liquid into the flushing water during the flushing cycle based on the time duration and the pressure profile of the flushing cycle; and
determining the start of a subsequent flush cycle and adding the liquid to the flushing water of the subsequent flush cycle at the desired time for the desired duration.

Abstract
A method for introducing liquid agents, such as cleansers or disinfectant, into the water supply of a sanitary facility, such as a water closet includes the monitoring of the pressure characteristics of a flush cycle and determining an appropriate time during the cycle for introduction of the liquid agent. A subsequent flush cycle is similarly monitored. At the determined time the agent is added. Preferably, the determined time is towards the end of the flush cycle. An apparatus for carrying out the method includes a liquid reception, a pressure sensor located in a line connecting the reservoir to the water supply line for the sanitary facility, and a control unit which operates either a pump or a valve. The liquid can be introduced into the water supply either by the pump or by suction.
