0010
As a specific configuration of the heat storage tank 30, an electric water heater using water as a heat storage medium is used. That is, the heat storage tank 30 is composed of a tank 30a and a heater 30b that uses electric power provided in the tank 30a. Hot water is supplied from the output side heat storage pipe 12. The principles of such electric water heaters include convection methods (natural convection, forced convection) and heat exchanger methods. It can be used as a water heater. A temperature detector 30c is also provided, and the temperature is controlled at a desired set temperature.
[0011]
If late-night electricity is used for the heat storage tank 30 (water heater), the electricity usage fee can be made relatively low. The late-night power sources include Mid-night power A and B (power used for hot water between 11:00 p.m. and 7:00 a.m. the next morning), Midnight power No. 2 (power used for hot water between 1:00 a.m. and 6:00 a.m.). There are various types of electricity (electricity used for electricity), etc., and the discount rates differ depending on each electricity company.
0012
Reference numeral 11 denotes an input side heat storage pipe, which is connected to the input side of the heat storage tank 30 , and one end of the output side heat storage pipe 12 is connected to the output side of the heat storage tank 30 . The other end (inflow side) of the input heat storage pipe 11 is connected to the connecting pipe 4 downstream of the circulation pump 1 of the bath water purification and circulation system A via a circulation path switching means 13. Further, the other end (outflow side) of the output side heat storage pipe 12 is communicated with the middle of the output side circulation pipe 6 via a first switching means 14 .
[0013]
A temperature measuring means 22 connected to the central processing unit 21 is provided in the middle of the input side circulation pipe 5 serving as the bath water purification and circulation device A, and measures the temperature of the bath water in the bath water purification and circulation device A. Accordingly, the valve control means 23 operates to appropriately switch the flow path for bath water, etc., so that a predetermined temperature can be controlled. Further, a desired temperature is stored in the set temperature storage means 24 in advance. This set temperature is configured as a RAM so that it can be changed as appropriate. Further, the central processing unit 21 is also provided with a temperature comparison means 25 for comparing the measured temperature and the set temperature. Further, a water supply valve 26 from another water source is also provided so as to be controllable by the valve control means 23 in order to lower the temperature of the bath water.
[0014]
Within an appropriate desired set temperature range (approximately 40 to 42° C.), the flow path of the circulation path switching means 13 does not flow out to the input side heat storage piping 11, but passes only through the bath water purification and circulation device A. In addition, the flow path of the first switching means 14 is configured so that only the inside of the bath water purification and circulation device A passes through [see FIG. 3(A)]. In addition, when the temperature decreases slightly (within about several degrees), the flow path of the circulation path switching means 13 passes through the heat storage tank 30 from the input side heat storage piping 11 side, and inside the bath water purification and circulation device A. The hot water in the heat storage tank 30 and the bath water in the bath water purification and circulation device A are mixed together and pass through the output side circulation pipe 6 via the first switching means 14. [See FIG. 3(B)]. Furthermore, when the temperature drops significantly (more than about several degrees), the flow path of the circulation path switching means 13 is blocked from passing through the bath water purification and circulation device A, and the flow path of the circulation path switching means 13 is switched from the input side heat storage piping 11 side to the heat storage tank 30. In addition, the flow path of the first switching means 14 also blocks passage of the bath water in the bath water purification and circulation device A, and the hot water stored only in the heat storage tank 30 is routed from the output side circulation pipe 6. [See FIG. 3(C)].
[0015]
Next, the process will be explained using the flowchart shown in FIG. First, the operation of the apparatus of the present invention is started. Then, the temperature measurement means 22 measures the temperature and determines whether it is within the set temperature range (see S1). If the temperature is within the set temperature range, the valve control means 23 controls the valve, and the circulation path switching means 13 The flow path is configured so that it does not flow into the input side heat storage pipe 11 and passes only through the bath water purification and circulation device A, and the flow path of the first switching means 14 is configured so that only the inside of the bath water purification and circulation device A flows through the bath water purification and circulation device A. [See S2 and FIG. 3(A)]. That is, when the circulation pump 1 in the bath water purification and circulation device A is started, the bath water is circulated through the bathtub 10, the input side circulation piping 5, the bath water purification and circulation device A, and the output side circulation piping 6 to perform sterilization, etc. . In this circulating state, the process returns to step S1. Further, the temperature is measured by the temperature measuring means 22 and it is determined whether the temperature is lower than the set temperature (see S3), and if the temperature is higher than the set temperature range, the valve is controlled by the valve control means 23. , the water supply valve 26 is opened to lower the bath water temperature (see S4). In this state of decreasing, the process returns to step S1.
[0016]
If the temperature is lower than the set temperature range, it is further determined whether the measured temperature is slightly lower (see S5), and if it is slightly lower, the valve control means 23 controls the valve to Bath water and thermal storage hot water circulate between the water purification and circulation devices A and between the heat storage tanks 30 to raise the bath water temperature (see S6). That is, the first switching means 14 is switched, and the heated hot water in the heat storage tank 30 and the bath water in the bath water purification and circulation device A are mixed together and pass through the output side circulation pipe 6 [FIG. 3] (B)]. In this way, the temperature of the bath water using the stored heat water is increased. While the temperature of the bath water is rising, return to the step before S1 and repeat. When the desired set temperature is reached in this manner, the same process as described above occurs. In addition, when the temperature decreases significantly (more than about several degrees) (in the case of NO in S5), the valve is controlled by the valve control means 23, and the thermal storage hot water including the bath water is circulated between the thermal storage tanks 30. Raise the temperature (see S7). That is, the flow path of the first switching means 14 is switched, blocking the bath water from passing through the bath water purification and circulation device A, allowing the stored hot water only in the heat storage tank 30 to pass from the output side circulation pipe 6, and changing the bath water. [See Figure 3(C)]. In this state, the process returns to step S1 and repeats the steps from S1 to maintain the set temperature of the bath water at all times.
[0017]
As a modification of the first embodiment, it may be possible to switch only between the case of FIG. 3(A) and the case of FIG. 3(B). Specifically, in the bath water circulation, there is a case where the bath water does not flow into the input side heat storage pipe 11 and passes only through the bath water purification and circulation device A [see FIG. 3(A)], and a case where the heat storage in the heat storage tank 30 In some cases, the hot water and the bath water in the bath water purification/circulation device A flow out into the bathtub 10 while being mixed together (see FIG. 3(B)). Furthermore, as a modification of the first embodiment, switching may be made only between the case of FIG. 3(A) and the case of FIG. 3(C). Specifically, in the bath water circulation, there is a case where the bath water does not flow into the input side heat storage piping 11 and only passes through the bath water purification and circulation device A [see Fig. 3 (A)], and when only the heat storage water containing the bath water flows out. may flow into the bathtub 10 [see FIG. 3(C)].
[0018]
Furthermore, in the second embodiment of the present invention, as shown in FIGS. 6 and 7, a second switching means 15 is used in place of the first switching means 14 of the first embodiment. In this case, rapid heating pipes 16 are provided from the 15 second switching means, and the temperature inside the bathtub 10 can be rapidly raised. The other configurations are the same as in the first embodiment. To explain its operation, when the temperature is within the set temperature range, the valve is controlled by the valve control means 23, and the flow path of the circulation path switching means 13 does not flow into the input side heat storage piping 11, and the bath water purification circulation system If the temperature is higher than the set temperature range, the valve is controlled by the valve control means 23, and the water supply valve 26 is opened. The bath water temperature is lowered, and when the temperature is slightly lower than the set temperature range, the valve is controlled by the valve control means 23, and the bath water and The heated hot water is mixed and circulated to raise the bath water temperature [see Figures 7 (B) and (C)]. In particular, in the case of Figure 7 (B), the heated hot water and the bath water flow out independently. In the case of FIG. 7(C), the heated hot water and bath water are mixed and flowed out at an appropriate temperature. Further, when the temperature decreases significantly (more than about several degrees), thermal storage hot water including bath water circulates between the heat storage tanks 30 to increase the bath water temperature [see FIG. 7(D)]. The flowchart is the same as in the first embodiment.
[0019]
In addition, in the third embodiment, as shown in FIGS. 8 and 9, the first switching means 14 of the first embodiment is removed, and the output side circulation pipe 6 and the output side heat storage pipe 12 are made independent. and each end thereof is provided so as to be able to flow out into the bathtub 10. When the temperature of the bath water decreases, this is measured by the temperature measuring means 22, and the heated hot water circulated to the heat storage tank 30 side is automatically flowed out to control the bath water to a desired temperature. has been done. In this case, what flows into the bathtub 10 is high-temperature thermal storage hot water that has been circulated through the thermal storage tank 30 and can be heated quickly. In addition, within the set temperature range, the bath water is configured to pass only through the bath water purification and circulation device A [see Figure 9 (A)], and when the temperature is a little low, it passes between the bath water purification and circulation device A and the heat storage tank. The bath water and heat storage hot water are circulated between 30 and 30 minutes to raise the bath water temperature [see FIG. 9(B)]. In this way, when bath water flows into the input side heat storage pipe 11 by switching the circulation path switching means 13, the heated hot water in the heat storage tank 30 automatically flows out from the output side circulation pipe 6 by that amount. . The other configurations are the same as those in the first embodiment, and their explanation will be omitted.
[0020]
Next, in the fourth embodiment, as shown in FIG. 10, the first switching means 14 and the input heat storage pipe 11 of the first embodiment (see FIG. 1) are removed, and the other configurations are as follows. This is the same as the first embodiment. In this fourth embodiment, especially when the temperature of the bath water decreases, only the heat storage water in the heat storage tank 30 is used, and although the amount of bath water in the bathtub 10 increases, it is different from the first embodiment. The configuration is relatively easy. In this case, only the first switching means 14 is controlled, and its operation is the same as in the first embodiment.
[0021]
Next, in the fifth embodiment, as shown in FIG. 11, the first switching means 14 and the input heat storage pipe 11 of the second embodiment (see FIGS. 6 and 7) are removed, and other configurations are used. is the same as the second embodiment. In this fifth embodiment, especially when the temperature of the bath water decreases, only the heat storage water in the heat storage tank 30 is used, and although the amount of bath water in the bathtub 10 increases, it is different from the second embodiment. The configuration is relatively easy. The operation of the fifth embodiment is also similar to that of the second embodiment.
[0022]
Next, in the sixth embodiment, as shown in FIG. 12, the first switching means 14 and the input heat storage pipe 11 of the third embodiment (see FIGS. 8 and 9) are removed, and other configurations are used. is the same as the third embodiment. In this sixth embodiment, especially when the temperature of the bath water decreases, only the heat storage water in the heat storage tank 30 is used, and although the amount of bath water in the bathtub 10 increases, it is different from the third embodiment. The configuration is relatively easy. The operation of the sixth embodiment is also similar to that of the third embodiment.
[0023]
In addition, in the seventh embodiment, as shown in FIG. 13, the bath water purification and circulation device A and the heat storage tank 30 are configured in series, and in this case, the bath water and the heat storage hot water are always mixed. In this case, it is particularly necessary to control the temperature inside the heat storage tank 30 to the desired temperature as bath water. , it is necessary to stop the circulation and raise the temperature of the hot water in the heat storage tank 30.
[0024]
In the first to seventh embodiments, in cold regions or the like, heating means 18 such as a sheathed heater may be provided as a component of the bath water purification and circulation device A, as shown in FIG. Furthermore, in the first to seventh embodiments, as shown in FIG. 15, the hot water supply equipment section 35 capable of providing a shower 35a may be made usable from the heat storage tank 30. The stored hot water from the shower 35a and water from a water source such as tap water are used to maintain an appropriate temperature. In the drawing, the heating means 18 is provided in the bath water purification and circulation device A, but it is applied to the first to seventh embodiments, and in FIG. 15, the hot water supply equipment in the first embodiment is 35, but this is also applicable to the other second to seventh embodiments.
[0025]
【Effect of the invention】
In the invention of claim 1, the bath water in the bathtub 10 is pumped up from the input side circulation piping 5 by the operation of the circulation pump 1, and is circulated through the bath water purification and circulation device A in which the sterilization device 2 and the filtration device 3 are installed. In a 24-hour bath water purification/circulation device that constantly keeps bath water clean by flowing it out from an output side circulation pipe 6 into a bathtub 10 after purification treatment, an input side heat storage pipe 11 is provided on the bottom surface, and an output side heat storage pipe 12 is provided on the top surface. A heat storage tank 30 is provided, which is connected to each other and has a heater 30b that uses electric power inside to store hot water. The valve control means 23 connects the circulation path switching means 13 to the input side circulation pipe 5 of the bath water purification and circulation apparatus A based on the bath water temperature measured by the temperature measurement means 22. The circulating bath water is switched so that it flows in three directions: to the side of the bath water purification and circulation device A alone, to the side of the heat storage tank 30 alone, and to both sides of the bath water purification and circulation device A and the heat storage tank 30. The 24-hour bath water purification and circulation device is controlled so that an amount of hot water corresponding to the amount of bath water that has flowed from the output side heat storage pipe 12 through the input side heat storage pipe 11 flows out, mixes with the bath water, and heats it. Therefore, in order to keep the water temperature of the bath water constant, the heat storage tank 30 that can heat the water using a power source is used, so if, for example, nighttime electricity is used to heat the heat storage tank 30, the power cost can be reduced. This makes it possible to provide a 24-hour bath water purification and circulation system at a lower cost. Since water is used as the heat storage medium, the cost of the heat storage material can be lowered, and because the heat storage tanks 30 are arranged in parallel, the bath water Temperature control is easy. Furthermore, since the heat storage tanks 30 are arranged in parallel, there is an advantage that there is no need to stop circulation (purification) even when heating is not required.
[0026]
The heat storage tank 30 uses cheap electricity such as late-night electricity, stores the heat in the heat storage tank 30, and uses it to heat the bath water. This also eliminates the need for power consumption, allowing for power savings. Moreover, in the invention of claim 1, when the temperature drops, the heated hot water flowing into the bathtub 10 can be directly caused to flow into the bathtub 10. Furthermore, since water is used as the heat storage medium, the heat storage material can be easily set when installing the heat storage tank 30, and is non-flammable and safe. Furthermore, even if there is a hole in the heat exchanger, there is no need to worry about contamination of the bath water, and there are advantages such as low corrosivity.
[0027]
In the invention of claim 2, the bath water in the bathtub 10 is pumped up from the input side circulation pipe 5 by the operation of the circulation pump 1 and circulated through the bath water purification and circulation device A in which the sterilization device 2 and the filtration device 3 are installed. In a 24-hour bath water purification/circulation device that constantly keeps bath water clean by flowing it out from an output side circulation pipe 6 into a bathtub 10 after purification treatment, an input side heat storage pipe 11 is provided on the bottom surface, and an output side heat storage pipe 12 is provided on the top surface. A heat storage tank 30 for storing hot water with a heater 30b that uses electricity is connected to each other, and the output side heat storage pipe 12 of the heat storage tank 30 is rapidly connected to the output side circulation pipe 6 of the bath water purification and circulation device A. The valve control means 23 switches the switching means provided on the output side circulation pipe 6 in response to switching of the circulation path switching means 13 provided on the input side circulation pipe 5. When the circulation path switching means 13 is switched to the side where the heat storage tank 30 is isolated, the switching means is switched to the side where the rapid heating pipe 16 is isolated so that the hot water flowing into the output side heat storage pipe 12 flows directly into the bathtub 10. By adopting a 24-hour bath water purification and circulation device that is controlled in this way, when the temperature of the bath water drops, the high-temperature stored hot water that flows into the bathtub 10 can be directly flowed in.
[0028]
In the invention of claim 3, the 24-hour bath water purification and circulation device according to claim 1 or 2 is further provided with a heating means 18 such as a sheathed heater in the bath water purification and circulation device. is valid for use.
