Abstract
PURPOSE:To prevent the lowering of the water level in a bathtub even when backwashing is carried out, to take a bath without discharging bathtub water used in the previous day and to prevent the floating of a malodor even when filtering operation is carried out by performing backwashing for a definite time prior to filtering at the time of the operation of a foam bath. CONSTITUTION:When an operation switch is turned ON and a foam bath operating switch is pushed for the first time, a circulation pump 5 is driven and three-way valves 25, 26, 16 are controlled and a flashing opening and closing valve 19 is controlled so as to be opened to perform backwashing for a predetermined time and, at the same time, an air amount control valve 37 is opened to realize a foam bath. Thereafter, the three-way valves 25, 25 are controlled to perform filtering operation. At this time, a foam bath state is held and hot water is sucked in a circulation circuit 2 from a bathtub 1 to be divided into the stream going to a filter circuit 23 and the stream emitted to the bathtub 1. The hot water flowing to the filter circuit 23 is decontaminated by a filter tank 22 to be again returned to the suction part of the pump 5 and the malodor in the filter tank 22 is removed by backwashing operation to be prevented from floating. Even when backwashing is carried out in the foam bath alternately subjected to filtering and backwashing, the water level in the bathtub 1 is not lowered.

を設け、該循環回路に濾過槽を有する濾過回路を接続し
、濾過槽よりも上流側の濾過回路から逆洗用排水回路を
分岐し、濾過槽よりも下流側には上水道と直結した逆洗
回路を合流させ、逆洗時には逆洗水を逆洗回路から濾過
槽を逆流させ、逆洗用排水回路へと流し、泡風呂運転時

特徴とする濾過装置。A foam ejector is provided at the bathtub outlet of a circulation circuit that circulates hot water in the bathtub, a filtration circuit having a filtration tank is connected to the circulation circuit, and a backwash drainage circuit is branched from the filtration circuit upstream of the filtration tank. However, on the downstream side of the filtration tank, a backwash circuit directly connected to the water supply is merged, and during backwashing, the backwash water is made to flow back from the backwash circuit to the filtration tank, and then to the backwash drainage circuit, allowing bubble bath operation. A filtration device that sometimes performs filtration, and is characterized in that it is configured to perform backwashing for a certain period of time prior to filtration during bubble bath operation.
