(以下逆洗という)に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath filtration device, and more particularly to backwashing (hereinafter called backwashing) of a filter inserted in a circulation circuit for circulating hot water in a bathtub.

されて泡が発生する。2. Description of the Related Art In a bath device such as a bubble bath, a filter is inserted in a circulation circuit for circulating hot water in the bath.
And in a simple bubble bath, a circulation pump is inserted in this circulation circuit, and the forced circulation force of this makes it suck air.
Circulating water is discharged from the discharge port provided in the bathtub together with suction air to generate bubbles.

方法が特公平4-28383 号公報に提案されている。During this forced circulation, the circulating hot and cold water is filtered by the filter. However, in this bubble bath device, since the circulation operation is frequently executed, the filtering ability of the filter is lowered and the cost is low. Further, if the filter is left for a certain period of time while being filtered, it may cause an offensive odor. Therefore, in order to recover the filtration capacity and prevent the generation of the bad odor, a method of giving a circulation flow to the filter in the direction opposite to the circulation direction during normal operation, that is, a method of performing so-called backwashing at a predetermined timing is known. It is proposed in Japanese Examined Patent Publication No. 4-28283.

る。また、悪臭の発生も防止出来る。In this prior art, during the backwash, clean tap water is introduced from a water circuit communicating with the circulation circuit and the backwash water passing through the filter is discharged to the outside. A method of executing the washing operation for a certain period of time before starting the bubble bath operation is adopted. Therefore, when the bubble bath operation is started after a certain period of time after the bubble bath operation operation, the filter is always in the back-washed state and the filtering ability is restored. Further, it is possible to prevent the generation of a bad odor.

とする。However, in this prior art, since the backwashing operation is always executed prior to the start of the bubble bath operation, a certain waiting time occurs during the bubble bath operation, which is inconvenient. The present invention has been made in view of such a point, and "A filter circuit having a filter is connected to a circulation circuit connected to a bath, and a backwash circuit is connected to the filter circuit to perform backwash. In a bath filtration device in which tap water is allowed to flow back to the filtration circuit during operation and is discharged to the outside, this forced circulation operation is executed promptly during forced circulation operation such as bubble bath operation, and filtration is started at the start of execution. The task is to ensure that the filter of the circuit is always backwashed.

That is.

状態にある。When the forced circulation operation end signal is input, the backwash control device executes the backwash operation for a certain period of time. Therefore, at the time of the next forced circulation operation, the filter is always in the backwashed state.

都合が解消できる。[Effect] When the forced circulation operation is started, the filter is always in the back-washed state, and the forced circulation operation immediately executes the forced circulation operation, thus eliminating the conventional waiting time. Furthermore, since the backwashing operation is executed after the forced circulation is completed, even if the hot water in the bathtub is drained after the final forced circulation operation, the filter is still backwashed at this time, so The inconvenience of being left without backwashing can be eliminated.

The signal at this time sets the three-way valve 31 and the three-way valve 32 to the backwash posture, and then the water filling valve 33 is opened to maintain this state for a certain period of time. As a result, the tap water supplied from the water filling circuit 3a flows backward through the filter 20 and is discharged from the drain circuit 3b. Therefore, in this embodiment, the water filling circuit is
