Abstract
PURPOSE:To take a bath without lowering the water level in the bathtub and discharging the used bathwater and to prevent development of rancidity even if the filter is operated by carrying out backwashing for a definite time when the operating switch is turned on and the water level is above a specified level. CONSTITUTION:The operating switch is turned on, the water level is detected following the procedure, and the water level is detected by a pressure sensor 7. The backwashing circuit 30 side and the tank filter 22 are communicated by a three-way valve 25 when the specified water level is exceeded, and the tank filter 22 side and a waste backwashing water discharge circuit 24 are communicated by a three way valve 26. Besides, a hot water supply circuit 3 and the backwashing circuit 30 are communicated by a three-way valve 16. Water is passed under these conditions, and backwashing is carried out for a specified time. A supplementary burning circuit 4 and the hot water supply circuit 3 are then again communicated by the three-way valve 16, the circulating circuit 2 side is closed by the three-way valves 25 and 26, and the supply of hot water is started.

なわせるよう構成したことを特徴とする濾過装置。A filtration circuit with a filtration tank is connected to the circulation circuit that circulates hot water in the bathtub, a backwash drainage circuit is branched from the filtration circuit upstream of the filtration tank, and the downstream side of the filtration tank is directly connected to the water supply. A water level detection means for detecting the water level in the bathtub is installed in an appropriate place in a device in which the backwash circuits are merged, and during backwashing, the backwash water flows back from the backwash circuit to the filtration tank and then to the backwash drain circuit. A filtration device, characterized in that it is configured to perform backwashing for a certain period of time if the water level is above a specified water level when the operation switch of the device is turned on.
