Abstract

PURPOSE:To accurately perform the washing of a filter medium and also to extremely inhibit the reduction of water in a bath by unnecessary backwash by constituting a filter so that backwash is automatically practiced in case filtering operation is performed at a preset time. CONSTITUTION:A controller 17 by which backwashing operation is practiced in case filtering operation time reaches preset time at a time of filtering operation is provided. As the controller 17, an apparatus performing the following functions is used. For example, a pump 2 is drived by the turning-on operation of a filtering operation switch 14, and the driving of the pump 2, changeover of a three-way valve 5 and the opening and closing of a solenoid on-off valve 9 are performed by the turning-on operation of a backwashing operation switch 15. Furthermore by the turning-on operation of a capacity changeover switch 16, the opening of the valve 9 is performed and also in case the integrated time of a built-in timer integrating the filtering operation time of a filter 6 reaches preset time, filtering operation is automatically changed over to backwashing operation and backwash is performed at a constant time and thereafter the timer is cleared to return the filter to filtering operation.

In the above configuration, when the filtration operation switch (14) is turned on when filtering the bathtub water, the three-way valve (5) is switched as shown by the solid line, and the pump (2) is driven. By driving the pump (2), some of the bath water flows into the circulation path (
3) to the first branch path (4) from the orifice (11), (1
2), the flow rate is restricted and flows through the first branch (4).
The bath water flowing through is filtered by a filter (6). At that time, if the filtration operation is waited for a set time, a backwash operation, which will be described later, is automatically executed during the filtration operation. Next, when cleaning the filter (6), press the backwash operation switch (15).
When turned on, the three-way solenoid valve (5) is switched to the state shown by the broken line, and the solenoid on-off valve (9) is opened.
