Abstract

PURPOSE: To prolong an interval of cleaning and replacing a filter medium for biological filtration and thereby improve ease of handling. CONSTITUTION: In a purification device for bath water consisting of a circulation path which connects a suction port 6 to a discharge port 7 through a pump 4 for circulating water in a bathtub and at the same time, a filtration means arranged in the circulation path for purifying bath water, the filtration means uses a granular fiber filter medium 40 as a filter medium, and a stirring and cleaning means for stirring the filter medium is provided. Compared to a granular porous filter medium, the granular fiber filter medium has a larger surface area and less pressure loss. In addition, it can easily shake off a sticking dirt by stirring and cleaning action, so that the interval of cleaning and replacing the filter medium can be prolonged.

2. Description of the Related Art In recent years, there have been provided baths for home use that allow bathing for 24 hours. in this case,
The bath water in the bathtub can be used for a long period of time.
It must be purified regularly or periodically. For this reason, this type of bath is equipped with a bath water purifying device which sucks up bath water in the bathtub, filters it with a filtering means, and returns it to the bathtub.

By the way, since the bath water contains sweat and proteins that are emitted from the human body and it is difficult to remove them by physical filtration, the filter medium used in the filtration means is one that simply performs physical filtration. Since it is impossible to use the bath water for a long time, biological filtration is performed. That is, a microorganism that decomposes or sterilizes sweat (ammonia) or protein is used, and for this reason, a granular porous filter medium on which the microorganism can grow is used as the filter medium.

On the other hand, since dirt in the bath water adheres to the filter medium, clogging is inevitable. At this time, if the filter medium is replaced, it will take time until the above-mentioned decomposition and sterilization action by the microorganisms propagated in the filter medium can be stably obtained. Therefore, the bath water can be run in the direction opposite to the normal condition in the filter containing the filter material,
It has been conventionally practiced to wash the filter medium by stirring the filter medium in the filter to eliminate clogging and make the filter medium usable for a long period of time.

Here, as the filter medium which is also a carrier for microorganisms, the granular porous filter medium such as the granular malted stone or the ceramic ball has been conventionally used as described above. In this case, The filter medium had to be frequently washed because it was clogged relatively early. Even if washing is performed, it is not possible to remove all the dirt adhering to the filter medium by only performing backwashing or stirring washing in the filter, and in order to perform sufficient washing, the filter medium should be taken out and washed. This is a must-have item, and eventually, the filter medium must be replaced, but the state in which it had to be replaced was early.

[0006] It is difficult for the user to determine when to wash the filter medium. Even if the user finds that the circulating flow rate has decreased, the circulating flow rate also decreases due to clogging of the filter for capturing hair etc. that is usually provided at the inlet of the bath water, so it is distinguished from this point. I have to do it. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a bath water purifying device which is easy to use and can extend the cleaning or replacement cycle of the filter medium for biological filtration. Another object of the present invention is to provide a bath water purifying device capable of accurately and easily detecting clogging of a filter medium.

However, this bath water purifying apparatus is installed in the vicinity of the bathtub, and the suction port 6 and the discharge port 7 are submerged in the bath water in the bathtub. The bath water sucked through the mouth 6 is circulated and filtered, and the temperature of the bath water is prevented from lowering when the sheath heater 3 is energized. When the granular fiber filter medium 40 of the filter 4 is clogged and the flow becomes poor, the pressure in the heater chamber 13 between the pump 2 and the filter 4 rises, and the pressure sensor 17 detects this. To inform
Alternatively, the cleaning operation described below is performed. When the filter 60 is clogged, the negative pressure generated on the suction port 6 side of the pump chamber 12 becomes large.
8 to prompt the user to wash or replace the filter 60. Whether or not it is in a clogging state is determined by comparing the pressure values detected by these pressure sensors 17 and 18 with the matrix table of the above-mentioned limit values, or using the membership function for the detected pressure values. By performing the fuzzy inference by performing the calculation based on the above calculation, not only the particulate fiber filter medium 40 and the filter 60 are clogged, but also the pump lock, the poor circulation due to the trapped air of the pump, the overflow due to the lid 11 being removed, and the pressure sensor 17 ,
18 abnormalities and the like are also discriminated.

The cleaning of the granular fiber filter medium 40 in the filter 4 is performed by operating the pump 2 and the stirring blade 45 by the motor 15.
Is performed and the drainage switching valve 9 is switched. The pump 2 can be rotated normally and reversely, and the pump 2 can be used for cleaning.
May be driven in reverse. Here, the granular porous filter medium and the granular fiber filter medium 40 which have been conventionally used
Comparing the cases where and are filled in the same volume of the filter 4, the granular fiber filter medium 40 has a larger surface area, a larger filtration performance, and a smaller pressure loss. It is more time consuming to use 40 in order to reach a clogging state, so that the cleaning cycle can be lengthened and the number of times of cleaning can be reduced, and in addition, the granular porous filter medium has dirt that is clogged inside its pores. Is difficult to remove by washing, while the granular fiber filter medium 40 has stains on its surface, so that it is easy to remove the stains by stirring and washing. The effect of recovering the filtration capacity by washing is higher, and the time until it becomes necessary to replace the filter medium is longer, and in addition, the performance for propagating microorganisms is Since unchanged with Jo porous filter media, particulate fibrous filter media 40 as filter media used in the bath water purifier for domestic use is very those advantages often.

Further, the granular fiber filter medium 40 can be agitated at the time of cleaning by the motor 15 having a small torque, and the agitating blade 45 is also of a pulsator type as in the embodiment shown in FIG. Is possible, in this case
Since the stirring blade 45 can also be installed on the lid 11 side, the substantial internal volume of the filter 4 can be set large, that is, the filling amount of the granular fiber filter medium 40 can be increased and the granular fiber filter medium 40 can be increased. And the stirring blade 45 can be easily maintained.
