きるようになっている。The jet flow generator is constructed by sequentially providing a jet flow circulation pump and a jet flow control valve on the way from the suction side to the discharge side of the jet flow circulation water channel, and the bath water is supplied by the jet flow circulation pump. Inhale,
It jets out from the wall of the bathtub as a jet stream containing bubbles. The jet amount can be adjusted by the jet flow rate control valve.

しないようにしている。Further, the bath water purifying apparatus comprises a purifying circulation pump, a filter tank, a biological filter bed tank, and a sterilizing device, which are sequentially connected on the way from the suction side to the discharge side of the purifying circulation water channel. Circulation pumps for hair, dust, dirt,
Inhale bath water containing soap, etc.
After removing relatively large suspended matter such as dust and dirt, the soap content and organic matter that are the nutrient sources of microorganisms are removed in the biological filter bed tank at the next stage, and further sterilized by a sterilizer before being sent into the bath. By repeating the procedure, the water in the bathtub is purified so that various bacteria do not propagate.

うにしている。When a biological filter tank is used as a bath water purifying apparatus, since it removes organic substances, etc., which are a source of propagation of various bacteria by the action of microorganisms, in order to maintain the purifying action by microorganisms, dissolved oxygen is always used. Must be secured. Therefore, when the bathtub is filled with hot water, the bathwater is constantly circulated to allow the hot and cold water mixed with air to flow into the biological filter tank to secure the dissolved oxygen.

立して取り付ける構成が採られている。As described above, in the case of using the biological filter bed as the bath water purifying device, it is necessary to constantly operate the purifying circulation pump to generate the water flow, while the jet flow generating device uses this. Whether or not to do so is selected each time according to the preference of the bather. Therefore, in the prior art, due to the difference in the usage mode of such a device, the jet flow generating device and the bath water purifying device are separately attached to the bath.

When the speed is high, the circulation rate of bath water per unit time is
Compared with the rate of decrease in turbidity at the beginning of purification
However, since the flow rate is faster, the removal efficiency of organic matter is higher.
Poorly, there is a limit to purification and the final turbidity increases.
On the contrary, when the flow rate of the biological filter bed is low, the
Although the efficiency of removing substances is high and the final turbidity is low,
However, since the circulation amount of bath water per unit time is small,
Especially in the first purification process where a large amount of organic substances are present, such as immediately after bathing.
In the period, the turbidity increases temporarily.

Large floating material is removed. Then, the hot and cold water that has passed through the filtration tank 22 is branched into two and enters the biological filter beds 26a and 26b through the three-way valves 24a and 24b, and organic substances such as fine dust and soap are removed.
At that time, since the dissolved oxygen in the biological filter beds 26a and 26b is supplied, the anaerobic state does not occur. Further, this hot water is sterilized by the sterilizer 28 and then returned from the discharge port 16aout to the jet flow circulating water channel 10 via the branch portion 16a of the purification circulating water channel 16 and is jetted by the jet flow circulating pump 12 to the jet flow circulating water channel. It is mixed with the hot water flowing in 10 and is jetted out into the bathtub 2 as a jet flow. In addition, a part thereof is again sucked into the purification / purification water channel 16.

A jet stream is generated and purification is performed at the same time. Further, in this mode, the water passage valve 30b of the other branch portion 16b of the purification circulation water channel 16 is closed, and the hot water of the purification circulation water channel 16 is returned to the jet flow circulation channel 10 from one branch portion 16a. Therefore, for example, even when operating the jet flow rate control valve 14a on the back side of the bathtub 2,
The amount of hot and cold water discharged from the discharge port 10aout is adjusted according to the adjustment amount, and there is no discomfort.

Hot water flows into a and 26b and into the sterilizer 28 for purification. Then, the purified hot and cold water is purified circulation water channel 1
From the other branch portion 16b of 6 through the branch portion 10a of the jet circulation water channel 10, the water is returned from the discharge port 10aout into the bathtub 2.

浄化を極めて効率良く行なうことができる。 In particular, in this example, one biological filter bed tank 26a
An orifice 44 is provided on the side of each biological filter bed tank 26a, 2
Since the flow rate in 6b is different,
In both operating modes (1) and (2), bath water
Purification can be performed extremely efficiently.

When the flow velocity of 6b is vb (where vb> va), as shown in FIG. 2, at a high flow velocity vb (indicated by a broken line in the figure), the circulation amount of the bath water per unit time is large, The rate of decrease in turbidity at the beginning of purification is relatively large. However, the flow velocity vb
However, the removal efficiency of organic matter is low, the limit of purification occurs, and the final turbidity increases. On the other hand, slow flow velocity
With va (shown by the one-dot chain line in the figure), although the removal efficiency of organic matter is high and the final turbidity is small, the circulation amount of bath water per unit time is small, so that it is especially In the initial stage of purification where a large amount of organic substances are present, the turbidity will temporarily increase. Therefore, as in this example, each biological filter tank 26 having a high flow velocity vb and a low flow velocity va is used.
If b and 26a are combined, as shown by the solid line in FIG.
This is convenient because the rate of decrease in turbidity at the early stage of purification, such as immediately after bathing, becomes relatively large, and the final turbidity can be reduced to some extent.

In addition, as shown in FIG. 3, the hot and cold water channel that has passed through one biological filter bed tank 26a is branched into two, one of which is directly connected to the biological filter bed tank 26b of the next stage, and the other is this biological filter tank. Even if the bed tank 26b is bypassed, since the flow rates of the biological filter beds 26a and 26b are different, the same effect as described above can be obtained.
