2. Description of the Related Art As a conventional method for controlling a bubble bath apparatus with a filtering device of this type, there is one described in Japanese Utility Model Publication No. 4-888. When the filtration operation switch is turned on, the bath water filtering apparatus of the same publication first performs backwashing for a predetermined time, and then shifts to the filtration operation.

As another conventional example, JP-A-3-60709.
There is one described in the publication. The method of the same issue is to carry out backwashing for a certain period of time during the first filtration operation after the bath water is refilled.

[0004]

The method of Japanese Utility Model Publication No. 4-888 has a problem that the backwashing operation is performed more frequently than necessary because the backwashing operation is performed every time the filtration operation is performed.

According to the method disclosed in JP-A-3-60709, backwashing is not performed on the second day when the remaining hot water in the bathtub is used for bathing again the next day. Therefore, filtration is performed with a filter that has not been backwashed, and the water that has accumulated in the filter (miscellaneous bacteria has considerably propagated) flows into the bath immediately after the start of filtration operation, and the bath water is removed. There is a problem of pollution.

A switch dedicated to backwashing is provided,
It is conceivable to operate this switch for backwashing if necessary, but it is not uncommon to forget backwashing.
In addition, backwashing becomes troublesome, and backwashing is often omitted and only filtration operation is performed.

A method for controlling a bubble bath device with a filtering device capable of backwashing, comprising backwashing the filtering device with water in the bathtub water and discharging backwash drainage to the outside of the bathtub. A bubble switch and a backwash bubble switch for backwash bubble operation are provided, and when the filter bubble switch is operated, a filter bubble operation is performed to supply bubbles while filtering, and the backwash bubble switch is operated. In this case, backwashing and bubble supply are performed for a predetermined time, and after this predetermined time has elapsed, filtration and bubble supply are performed.

According to a second aspect of the present invention, there is provided a method for controlling a bubble bath apparatus with a filtering device, wherein the method according to the first aspect further comprises alarm means that is activated when backwashing is required.

That is, according to the present invention, as a switch for filtration operation, there are two types of switches, a switch for filtration and bubble operation, and a switch for performing filtration and bubble operation after backwashing first. Is provided.

[0010]

When the filter bubble switch is operated, a filter bubble operation is performed in which bubbles are ejected while filtering.

When the backwash bubble switch is operated, first the backwash bubble operation is performed in which bubbles are ejected while backwashing, and then the filtration bubble operation is performed in which bubbles are ejected while filtering.

In the method of controlling the bubble bath apparatus with a filtering device of the present invention, a bather who intends to bathe in a bubble will select either the filter bubble switch or the backwash bubble switch. When the bather feels that washing is necessary, he or she may operate the backwash bubble switch.
Then, bubble ejection and backwashing are performed, and thereafter, the operation automatically shifts to filtration and bubble ejection. Therefore, the backwash bubble operation and the subsequent filtration and bubble ejection operations can be performed by only one switch operation, and there is no trouble for the bather. Therefore, backwashing can be appropriately performed as necessary, and contamination of bath water is prevented.

In the method for controlling a bubble bath apparatus with a filtering device according to a second aspect of the invention, warning means such as a warning lamp is activated when, for example, the total filtering time from the previous backwash exceeds a predetermined time. This allows the bather to perceive that it is time to backwash.
