It can also be performed at any time by operating a sterilization operation switch (not shown) provided on the operation panel 12.
[0043]
The feature of the present invention lies in the configuration of the hair catcher F disposed in the bath water circulating filtration device A.
[0044]
That is, as shown in FIGS. 3 and 4, the hair catcher F includes a cylindrical outer case 5 provided with a bath hot water inlet 50 at the bottom and a bath hot water outlet 51 at the upper side wall. It is inserted into the outer case 5 so as to shut off the bath water inlet 50 and the bath water outlet 51, and the bath water inlet 60 for introducing the bath water flowing in from the bath water inlet 50 into the upper part. A cylindrical inner case 6 formed on the peripheral wall, and a cylindrical shape disposed in the cylindrical inner case 6 and surrounding the mesh 70 and communicating with the bath outlet 51 of the cylindrical outer case 5 inside. The filter main body 7 is provided.
[0045]
In addition, a lid 8 can be fitted to the cylindrical outer case 5 via a sealing material 80 made of an X ring, and the lid 8, the cylindrical filter body 7 and the cylindrical inner case 6 The cylindrical filter body 7 and the cylindrical inner case 6 can be inserted into and removed from the cylindrical outer case 5 together with the lid 8.
[0046]
That is, as shown in FIG. 6, when the hair catcher F is maintained so that the cylindrical outer case 5 can be inserted and arranged from the upper end surface of the apparatus main body 11 of the bath water circulating filtration apparatus A, the apparatus main body It can be easily attached or detached by removing one lid 1a. 5a is a locking flange (see FIGS. 3 and 4).
[0047]
A fitting flange 61 is formed on the outer side in the vicinity of the upper end of the cylindrical inner case 6, and a filter locking portion 62 for locking the flange portion 71 formed on the upper end of the cylindrical filter body 7 is formed on the inner side. Furthermore, a substantially L-shaped engagement notch 63 is provided on the upper peripheral wall 6a, and an engagement protrusion 81 projecting from the lower peripheral wall 8a of the lid 8 can be engaged with the engagement notch 63. Yes.
[0048]
3 and 4, 52 is a mounting portion provided on the peripheral wall of the cylindrical outer case 5, 82 is formed near the lower end of the lid 8, and the inside of the cylindrical filter body 7 and the cylindrical outer case 5 An opening that communicates with the bath outlet 51 (see arrow f1), 83 is a locking projection provided on the peripheral wall of the lid 8, 53 is a notch corresponding to the locking projection 83, The case 5 is provided from the locking flange 5a to the upper peripheral wall 5b (see FIG. 3).
[0049]
Further, the bath hot water inlets 60 formed in the cylindrical inner case 6 are formed at two positions shifted in position as shown in FIG. The piece 65 is extended in the tangential direction, and the tip is brought into contact with the cylindrical outer case 5.
[0050]
With such a configuration, as indicated by an arrow f in FIG. 4, the bath water introduced from the bath water introduction port 60 can pass through the mesh 70 of the tubular filter body 7 while turning. This swirling flow produces a washing effect, and no biofilm is generated on the mesh 70 surface, so that the hygienic state can be maintained well, and the hair of the mesh 70 can be effectively washed away. Since clogging can be prevented as much as possible, the number of times the hair catcher F is washed can be greatly reduced.
[0051]
And when cleaning, as described above, it can be easily disassembled into the cylindrical outer case 5, the cylindrical inner case 6, and the cylindrical filter body 7, and the assembly is also easy. In addition, since there is little tangling of the hair, the cleaning time can be shortened, and the maintenance becomes very easy.
[0052]
Further, the mesh 70 is provided around a position spaced from the upper end of the tubular filter body 7 by a predetermined distance L.
[0053]
That is, the bath water flowing from the bath hot water inlet 60 of the cylindrical inner case 6 immediately flows into the inside from the vicinity of the upper end of the cylindrical filter body 7 and is directly provided on the upper side wall of the cylindrical outer case 5. This is to prevent the entire vertically long mesh 70 from being efficiently washed with the swirl flow by preventing the flow from the outlet 51.
[0054]
In this way, if this hair catcher F is used, the entire interior including the mesh 70 can be surely heat sterilized, and the hair catcher F which is easy to propagate various germs can be kept clean and the mesh which is a main part can be maintained. Since the washing effect of 70 can be caused, the maintenance interval such as cleaning of the hair catcher F can be extended significantly, and cleaning can be easily performed.
[0055]
Here, the case where the thermal sterilization operation is actually performed in the bath water circulating filtration device A according to the present embodiment will be described.
[0056]
FIGS. 8A and 8B show the flow of bath water during the filtration operation and the heat sterilization operation.
[0057]
The bath water circulating filtration device A normally performs a filtration operation. In that case, as shown in FIG. 8 (a), the bath water is bath water suction part 20 → hair catcher F → circulation pump P → five direction. Valve V (inlet V5 → first communication port V1) → UV sterilizer S → filter Q → 5-way valve V (second communication port V2 → third communication port V3) → three-way valve D (second port D2 → 1st port D1) → circulates with bath water discharge port 30.
[0058]
At this time, the temperature of the bath water is monitored by the bath water temperature sensor E connected to the control device, and if the temperature is lower than the set temperature, an energization signal to the heater H is output from the control device and heated. The bath water is always kept at the set temperature.
[0059]
At the predetermined time, the heat sterilization operation is started. At this time, the control device outputs a flow path switching signal to the three-way valve D to circulate the hot water in the sterilization flow path RC in the apparatus main body 1 and the heater H. A temperature rise signal is output to the bath water temperature to 60 to 80 ° C., and this temperature is controlled to be maintained for 10 minutes.
[0060]
That is, as shown in FIG. 8 (b), the bath water is a circulation pump P → 5-way valve V (inlet V5 → first communication port V1) → ultraviolet sterilizer S → filter Q → 5-way valve V ( Second communication port V2 → third communication port V3) → three-way valve D (second port D2 → third port D3) → bypass channel R1 hair catcher F → circulation only in the sterilization channel RC of circulation pump P.
[0061]
At this time, since the heater H is provided in the lower part of the filter Q, the heat sterilization can be effectively performed against various germs that easily grow in the filter medium Q1.
[0062]
In particular, Legionella spp. Which are problematic by causing pneumonia are known to be killed when heated at 60 ° C. for 5 minutes, and can be reliably killed according to the present invention.
[0063]
Moreover, since hot water of 60-80 ° C circulates up to the hair catcher F, it is possible to sterilize acid-fast bacteria that easily grow in the hair catcher F, and bathers can perform hygienic bathing without fear of infection. .
[0064]
In addition, after the heat sterilization is completed, the three-way valve D is controlled so that the hot water is circulated in the hot water circulation channel R so that heat can be exchanged between the hot water and the hot water in the bathtub. The flow rate is controlled so that it is at least a half of the flow rate during the filtration operation and the flow rate during the heat exchange operation is smaller than the flow rate during the heat sterilization.
[0065]
More specifically, the circulation flow rate in a normal filtration operation or the like is 13 liters per minute (L / min), and during the sterilization operation of about 30 minutes, the rotation of the circulation pump P is controlled to reduce the circulation flow rate to 5.6. L / min. Further, during the subsequent heat exchange operation, the circulation flow rate is set to 0.5 L / min. The flow rate during the heat exchange operation is maintained until the bath temperature reaches 45 ° C. The temperature detection at this time is detected by the thermistor T.
[0066]
By the way, the flow rate of 5.6 L / min is a flow rate at which cavitation does not occur even in high-temperature water, and the flow rate of 0.5 L / min is about 5 cm by a person at the bath water discharge port 30 opened in the bathtub. The flow rate is such that the heat is not felt even when the distance is approached, and both are experimentally determined.
[0067]
With the above configuration, the amount of heat used for heat sterilization can be recovered and the heat energy can be used effectively, so there is no loss of heat and it is efficient and energy saving, resulting in a large power saving effect. .
[0068]
Moreover, even if a bather enters the tub during the sterilization operation or immediately after the sterilization operation, the hot water flowing out from the hot water discharge port is small enough to prevent burns if mixed with the hot water in the tub. It is extremely safe because it is narrowed down.
[0069]
As described above, in the present embodiment, the hair catcher F has been described as being disposed in the hot water circulating filter device A, but is not necessarily limited to being disposed in the hot water circulating filter device A. It can be widely used as a filter device provided in the.
[0070]
