生装置等の装置を付加したものがある。In this bath water purifying apparatus, for example, a filter for filtering suspended matters in a forced circulation path of the hot water forcibly sucking the hot water in the bathtub by the circulation pump and discharging it again into the bathtub. A filtration tank loaded with the above, a circulation pump for forcedly circulating hot water, a heater for keeping the hot water at an appropriate temperature, an activation tank for activating the hot water, and a bath water in the bathtub. There is a device to which a device such as an ozone generator for sterilizing is added.

するために流量を検出する必要があった。With respect to the flow rate of hot water in the circulation path, such a bath water cleaning device is a filter in a filtration tank or activated carbon in an activation tank, which is obtained by continuously using the cleaning device for a long time.
When the flow rate of the hot water circulating in the circulation path gradually decreases as the activated stones etc. are clogged, and if a situation occurs in which the suction port or discharge port of the circulation path is blocked by foreign matter, etc. Since the flow rate of the hot water in the circulation path sharply decreases and causes the inconvenience described later, it is necessary to detect the flow rate in order to cope with it.
【0005】従来は、循環路中の流量の検出のために、

フロートスイッチ型の水流センサーを配設していた。Conventionally, in order to detect the flow rate in the circulation path,
A float switch type water flow sensor for detecting a change in the flow rate of hot water as shown in FIG. 5 was disposed in the circulation path.

A case 1 provided with a case 1 and a water outlet 3 vertically attached to the case 1, a reed switch 5 is provided in the upper part of the case, and a reed switch 5 is provided outside the case 1.
The switch body from which the two signal lines 6 are drawn is attached, and the shaft portion 7 extends downward from the switch body.
The shaft 8 is fitted with a float 8 which is vertically movable and a spring 9 which biases the float 8 containing a magnet upward.

ので、リードスイッチはONになっている。In the present embodiment, the reed switch 5 is of a type that is turned off when magnetism is applied. In this water flow sensor, hot water enters the case 1 through the water inlet 2 and goes out through the water outlet 3. Meanwhile, when the flow rate of the hot water is in the normal range, the float 8 is pushed downward by the pressure of the hot water flowing against the spring 9, and the magnetism does not act on the reed switch 5, so the reed switch is turned on. There is.

ている。On the other hand, when the flow rate of the hot water in the float 8 decreases, the force of the hot water to push the float 8 downward becomes weaker, and the spring 8 pushes it upward, and the magnetism of the float 8 acts on the reed switch 5 to cause it. Is turned off, and this signal is sent to the control device by the signal line 6 to detect the decrease in the flow rate.

Furthermore, these sliding surfaces may be clogged with fragments of activated stones or activated carbon, which may cause the water flow sensor to malfunction.

た場合等には循環路中の湯の流量が急激に減少する。As described above, the flow rate of hot water circulating in the circulation path gradually decreases as the filters in the filtration tank and the activated carbon, activated stones, etc. in the activation tank continue to be clogged due to continuous use of the cleaning device. The flow rate of hot water in the circulation path sharply decreases when a situation occurs such that the suction port and the discharge port of the circulation path are closed by foreign matter.

る。When the flow rate of hot water in the circulation path decreases to a certain value or the flow rate sharply decreases (hereinafter referred to as water shortage) due to long-term continuous use, there is a degree of difference between these two cases. The circulation pump was run dry, damaged due to heat generation, etc.
An inconvenient problem occurs that damages the cleaning device.

If it cannot be detected, or if the flow rate suddenly decreases, there is a risk that the cleaning device may malfunction due to idle operation of the circulation pump, abnormal overheating of the heat retention heater, or the like.

It has the effect of cleaning the filter media, and if the flow rate drops sharply, stop the operation of the cleaning device, and run the conventional circulating pump idle operation or abnormal heating of the heat retention heater. There is an effect that can be solved.

OMに記憶されている。FIG. 2 shows the relationship between the temperature difference and the flow rate. That is, the two hot water temperatures detected by the first hot water temperature sensor 29 installed on the front side of the warm water heater 13 and the second hot water temperature sensor installed on the rear side of the warm water heater 13 in the flow direction of hot water in the circulation path. As a result of experiments, it has been found that the relationship between the temperature difference and the flow rate of hot water in the circulation path has a relationship as shown in FIG.
According to this, as the flow rate decreases, the hot water is further heated when passing through the heat retention heater 13, and the temperature difference increases. Figure 2
The relationship between the temperature difference and the flow rate shown in FIG.
It is stored in OM.

っている。If a water shortage occurs during the operation of the cleaning device, the temperature difference between the hot water temperatures detected by the first hot water temperature sensor 29 and the second hot water temperature sensor 34 becomes large.
Water shortage is detected by comparing with the temperature difference data preset in the OM. If the lack of water is caused by the continuous use of the cleaning device for a long period of time, the display device 33 finely determines whether the content of the filtration tank or the activation tank is clogged, and the deterioration of the activation capacity is finely determined, and it is time to wash the water. It is designed to display.

ておきこれとの比較で行うこともできる。Further, in the case of a rapid decrease in the flow rate, the temperature difference between the hot water temperatures detected by the first hot water temperature sensor 29 and the second hot water temperature sensor 34 is smaller than that in the case of water shortage due to the long-term continuous use. This value becomes larger, and this value is compared with the temperature difference data that is set in advance in the storage device ROM and is larger than the previous one, and a sharp decrease in the flow rate is detected. In this case. The operation of the cleaning device is automatically stopped to ensure safety. This rapid decrease of the flow rate is performed by comparison with the temperature difference data stored in the storage device ROM, but instead of this, the data of the time change of the temperature difference is stored in the storage device. It can also be done by comparison.
