う。Within an appropriate desired set temperature range (about 40 to 42 ° C.), the solenoid valve 4 is closed, and the bath water is configured to pass through the bath water purifying device B and the output side circulation pipe 16, and When the temperature measuring means 21 in the bath water purifying apparatus B detects that the temperature of the hot water in the bathtub 10 has dropped, the valve control means 22 outputs a signal to open the solenoid valve 4, and the solenoid valve 4
Opens. Then, the throttle part 5 of the ejector A for hot water mixing
Since c is smaller than the inner diameter of the other output side circulation pipe 16, the flow velocity is fast, and the pressure becomes lower than that at the branching point T in the middle of the output side circulation pipe 16.
A part of the bath water circulating in the bath (bath water) flows to the hot water storage tank 1 side. In the Bernoulli's theorem and the Venturi tube principle in FIG. 4, a negative pressure with a virtual height difference h is generated at the six hot water inflow portions. The hot water in the hot water storage tank 1 in the amount of the inflow of the bath water flows out from the output-side hot-water storage pipe 3 and flows from the throttle portion 5c of the hot-water mixing ejector A into the mainstream of the output-side circulation pipe 16 of the bath water purifying apparatus B. The temperature of the hot water in the bathtub 10 is raised by being mixed with the bath water.

テップの手前に戻る。Next, description will be made with reference to the flowchart shown in FIG. First, the operation of the device of the present invention is started. Then, the temperature measuring means 21 measures to determine whether or not it is within the set temperature range (see S1). If it is within the set temperature range,
The solenoid valve 4 is closed by the valve control means 22 so that the bath water passes from the bath water purifying apparatus B only through the main stream of the output side circulation pipe 16 (see S2). That is, when the circulation pump 11 in the bath water purifying apparatus B is started,
0, the input side circulation pipe 15, the bath water purifying device B, and the output side circulation pipe 16 circulate the bath water for sterilization. In such a circulating state, the process returns to the step before step S1. Further, the temperature is measured by the temperature measuring means 21 to determine whether or not the temperature is lower than the set temperature (see S3). When the temperature is higher than the set temperature range, the valve control means 22 controls the valve. , The water supply valve 25 is opened to lower the bath water temperature (S
4). With this, the state is lowered, and the process returns to the step before step S1.

るように構成されている。When the temperature is lower than the set temperature range, the valve control means 22 controls the valve to open the solenoid valve 4, and the venturi pipe action of the hot water mixing ejector A causes the bath water to flow. Part of the hot water in the hot water storage tank 1 flows into the hot water storage tank 1 side, and the hot water in the hot water storage tank 1 flows out from the output side hot water storage pipe 3 and the throttle portion 5c of the hot water mixing ejector A.
The temperature of the hot water in the bathtub 10 is raised by mixing with the mainstream bath water in the output side circulation pipe 16 of the bathtub hot water purifying apparatus B (see S5).
Even while the bath water is warming up, it returns to the front of S1 and repeats. In this way, when the desired set temperature is reached, the process is the same as described above, and the bath water is always set at the set temperature.

温度は変わらないが昇温速度は速くなることになる。EXAMPLE The graph shown in FIG. 8 shows the relationship between the total flow rate and the hot water flow rate. That is, the horizontal axis represents the total flow rate (bath water amount + hot water flow rate) in liters per minute, and the vertical axis represents the hot water flow rate flowing from the throttle portion 5c of the hot water mixing ejector A in liters per minute. It is shown. When the flow rate of hot water through the throttle portion 5c of the ejector A for hot water mixing increases, the total flow rate also increases. As a result, the ratio of the hot water flow rate to the total flow rate (this ratio is also referred to as "hot water mixing ratio"). ) Is about 8.5 to about 9%. As described above, since the ratio of the hot water flow rate to the main flow rate of the output side circulation pipe 16 of the bath water purifying apparatus B is always constant, if the temperature of the stored hot water in the hot water storage tank 1 is constant, the bath hot water purification is performed. Even if the flow rate of the device B changes due to clogging or the like, the temperature difference between the hot water discharged from the hot water outlet 18 and the hot water of the bathtub does not change. In other words, if the flow rate decreases due to clogging of the filter medium, or if there is a mischief
This means that the temperature of the hot water coming out of the hot water outlet 18 does not change even when the flow rate of the water 7 or the hot water outlet 18 is blocked suddenly. Further, when the flow rate of the circulation pump 11 of the bath water purifying apparatus B can be changed, if the circulation is performed at a high speed, the hot water outlet temperature of the hot water outlet 18 does not change, but the temperature rising rate becomes faster.

にならないようにすることが肝要である。FIG. 9 shows a graph of the relationship between the mixing ratio and the outlet temperature, and in the apparatus of the present invention, the hot water flow rate of 85 ° C. in the hot water storage tank 1 is located at the hot water mixing ejector A location. For the total flow rate (bath water + hot water flow rate)
It shows the temperature coming out from the tap hole 18 when mixed at a ratio of 5, 10, 15, 20, 25, 30%. For example, when the bath water is bathed at 42 ° C, it is heated (when the installation temperature is 43 ° C or higher and the device determines that the temperature of the bath water is low and the solenoid valve 4 is opened to mix hot water). The temperature of the hot water coming out of the sprue 18 is 44 when the hot water mixing ratio is 5%.
About 30 ° C, 55 ° C at 30%. When the temperature of the hot water discharged from the hot water outlet 18 exceeds 50 ° C., it feels quite hot, so it is preferable to design the hot water mixing ratio to be 15% or less. Considering that the hot water is spouting from the hot water outlet 18 and hits the human body, it is important to prevent the temperature from becoming too high.
