[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a bath water purifier.
[0002]
[Prior art]
In recent years, bath water purifiers that circulate and purify bath water in bathtubs have become widespread. As shown in FIG. 11, a circulating water pump P is provided inside the bath water purifier, and the circulating water P enters the bath water from the bathtub B and performs predetermined processing such as filtration, sterilization, or heating. In addition, water is poured into bathtub B.
In such a bath water purifier, it is necessary to drain water from the inside of the apparatus and piping when cleaning and maintaining the inside of the apparatus. Therefore, after washing or maintenance, the inside of the apparatus and piping must be filled with water before use. However, there was a problem that it took time to fill the water.
[0003]
[Problems to be solved by the invention]
In order to eliminate this drawback, it is sufficient to use a self-contained pump as a circulation pump. However, the self-contained pump is expensive, and its structure has a high closing pressure. In addition, the cost is further increased, and the improvement of the self-sufficiency performance is limited, and further long-term self-sufficiency operation causes problems such as shortening the pump life.
The present invention aims to remedy the drawbacks of the prior art described above.
[0004]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a bath water purifier that discharges bath water after purification into a bathtub after the bath water is poured from the bathtub and subjected to a predetermined purification treatment. A non-self-contained pump for circulation, a self-contained pump disposed in parallel or in series with the non-self-contained pump, the non-self-contained pump during normal operation, and the self-contained pump during water filling A control device that performs a water filling operation and controls to switch to the operation of the non-self-contained pump when a water filling state is confirmed; and a means for providing a reference time required for water filling by the self-contained pump, and the control device Is characterized by recognizing the water filling condition based on the reference time from the means for providing the reference time .
With the above-described configuration, the self-contained pump can be filled with water to the apparatus and piping without manual work. Further, since the self-contained pump is used only when it is filled with water, it may be of a small capacity, so that it is not necessary to increase the pressure resistance performance of the apparatus itself or the piping, and the cost can be reduced. It is also possible to improve the self-sufficiency performance and extend the life of the pump.
Further, the means for giving the reference time includes a water filling timing timer and a memory for storing the water filling reference time, actually performing water filling, and determining the reference time necessary for water filling by the time counting timer, A reference time can be stored in the memory. In the case of this configuration, since the water filling time is actually measured and used as the reference time, there is an effect that an accurate reference time can be obtained.
Also, at the start of operation by operating the operation start key or the like, a water filling operation is performed using the self-contained pump, and when the state of water filling is confirmed, control is performed so as to switch to the operation of the non-self-contained pump and perform a normal operation. It is also possible to configure as described above. In this configuration, the water filling operation is always performed automatically at the start of operation, so that an accident caused by forgetting water filling can be prevented.
