[0014]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the present invention will be described based on the piping diagram of the embodiment of FIG. 1, but the same components as those in the conventional example are denoted by the same reference numerals.
[0015]
In order to form a so-called backwash conduit for cleaning the filter medium filled in the filtration tank 5 by flowing hot water in the reverse direction in the case of cleaning, the cleaning conduit 14 has an L-shape and a T-shape. Switching valves 15 and 16 are provided.
[0016]
In addition, since the ultraviolet sterilizer 17 is provided as a sterilizer, the intake pipe 12 is not connected as in the conventional example, but of course, the jet nozzle 11 having the intake pipe 12 connected to the tip of the fountain pipe 9 as in the conventional example. Install it so that you can enjoy a bubble bath.
[0017]
Reference numeral 18 denotes a hot water temperature regulator, and the hot water temperature regulator 18 is provided with a bathtub hot water inlet 19, a high temperature hot water inlet 20 and a hot water outlet 21.
[0018]
Reference numeral 22 denotes a hot water storage tank as hot water supply means. One end of a hot water supply pipe 23 is connected to the upper surface of the hot water storage tank 22, and the other end of the hot water supply pipe 23 is a hot water temperature controller of the cleaning pipe 14. The other end of the water inlet pipe 24 connected to the hot water inlet 20 at 18 and one end connected to the bottom surface is connected downstream of the electric heater 7 to the cleaning pipe 14, and the heater 25 is a heater using midnight power.
[0019]
Therefore, in this embodiment, the hot water is stored in the hot water storage tank 22 as hot water by being heated by the heater 25 using late-night power, but the hot water is heated using solar heat, In some cases, it may be heated by ordinary electric power and stored as hot water.
[0020]
Further, the water intake pipe 24 may be placed connected to a water heater that heats tap water with a cheap heat source such as kerosene or gas, and the tap water heated by the water heater may be stored as hot water in a hot water storage tank.
[0021]
Next, the configuration of the hot water temperature regulator 18 will be described in detail with reference to FIGS. 2 and 3. In FIG. 2, reference numeral 26 denotes a mixing chamber, and the mixing chamber 26 has a valve hole 28 in the center on the upper surface. It is a valve seat 27, a bath hot water inlet 19 is provided on one side surface, a hot water inlet 20 leading to the valve seat 27 is provided on the other side surface, and a hot water outlet 21 is provided on the lower surface.
[0022]
29 is a flow control valve, and a valve shaft 30 for opening and closing the valve hole 28 of the valve seat 27 is fixedly attached to the lower end of the valve shaft 30 of the flow control valve 29 and flows into the mixing chamber 26 inside. A wax 33 as a thermo element whose volume changes according to the temperature of the bath water is filled, and a thermostat 32 in which a piston 34 whose lower end abuts against the wax 33 is vertically movable is fixedly fitted. .
[0023]
Reference numeral 35 denotes a guide pipe extending above the mixing chamber 26 so that the valve shaft 30 of the flow rate adjusting valve 29 can be moved up and down, and 36 is fitted to the upper end of the guide pipe 35 and is predetermined according to the set temperature of the bath water. A pressing shaft fixed at the position 37 is a plurality of pressing springs for pushing the flow rate adjustment valve 29 upward.
[0024]
The valve cylinder 31 fixedly attached to the lower end of the valve shaft 30 of the flow rate adjusting valve 29 is as shown in FIG. 3, and the upper half is a hot water closing cylinder 38 that is a cylinder that closes the valve hole 28. The lower half is a hot water barrel 39 which is a cylinder provided with a plurality of cutout grooves 40 at a predetermined interval, and an attachment hole 41 for attachment to the valve shaft 30 is provided at the center.
[0025]
Therefore, the flow rate adjusting valve 29 attaches the valve cylinder 31 to the lower end of the valve shaft 30 through the mounting hole 41, and then sets the valve cylinder 31 into the valve hole 28 of the valve seat 27 and the valve shaft 30 with respect to the mixing chamber 26. Is fitted to the guide tube 35 so as to be movable up and down, and is pushed upward by a plurality of pressing springs 37, and is deployed while pressing the upper end of the piston 34 from above with a pressing shaft 36.
[0026]
When the flow control valve 29 is provided in the mixing chamber 26 in this way, the valve cylinder 31 is pushed upward, and the lower portion in which the notch groove 40 is provided at the position of the valve hole 28 of the valve seat 27. Since the hot water barrel 39 is located, the valve is open.
[0027]
A state in which the hot water temperature of the bathtub hot water forcibly circulating the cleaning pipe 14 using the hot water temperature controller 18 having the above-described configuration is heated with the hot water stored in the hot water storage tank 22 to maintain the appropriate temperature is shown in FIG. explain.
[0028]
First, when the operation of the apparatus is started, the hot water temperature regulator 18 is configured so that the flow rate adjusting valve 29 is pushed upward by the holding spring 37 and the valve cylinder 31 is moved as shown in FIG. 39 is located in the valve hole 28 of the mixing chamber 26 and is in an initial setting state where the valve is open.
[0029]
When the operation of the apparatus is started in this state, the switching valves 15 and 16 are switched in the direction of the cleaning process, so that the hot water 2 in the bathtub 1 pumped up from the hot water suction pipe 3 by the circulation pump 6 is obtained. After being sterilized by the ultraviolet sterilizer 17, it is filtered by the filtration tank 5 and flows through the cleaning pipe 14 through the electric heater 7.
[0030]
At this time, when the microcomputer controlling the apparatus as a whole determines that the auxiliary heating by the electric heater 7 is necessary based on the relationship between the outside air temperature and the amount of hot water stored in the hot water storage tank 22, the heating by the electric heater is performed.
[0031]
Further, as described above, the flow rate adjustment valve 29 provided for the hot water inlet 20 of the hot water temperature regulator 18 is opened so that hot water can flow into the mixing chamber 26 from the hot water supply pipe 23, and further hot water storage. The other end of the water inlet pipe 24 whose one end is connected to the bottom surface of the tank 22 is connected to the cleaning line 14 between the electric heater 7 and the hot water temperature regulator 18.
[0032]
Accordingly, the hot water 2 that circulates in the cleaning pipe 14 and passes through the electric heater 7 flows through the cleaning pipe 14 toward the hot water temperature controller 18 and also flows from the water inlet pipe 24 toward the hot water storage tank 22.
[0033]
As a result, the bath water 2 that has flowed through the cleaning pipe enters the hot water temperature adjusting device 18 from the bath water inlet 19 and hot water stored in the hot water storage tank 22 is supplied only for the amount of bath water that entered from the bottom. It is pushed out by the pipe 23 and enters from the hot water inlet 20.
[0034]
Therefore, in the hot water temperature regulator 18, the hot water stored in the hot water storage tank 22 is mixed with the bathtub hot water 2 circulated through the cleaning pipe 14 in the mixing chamber 26 and entered into the hot water temperature regulator 18, and is heated and heated. 21 returns to the cleaning line 14 again and returns to the bathtub 1 from the fountain pipe 9.
[0035]
Thus, as shown in FIG. 5A, the flow rate adjustment valve 29 for the hot water inlet 20 of the hot water temperature regulator 18 is opened, and the hot water stored in the hot water storage tank 22 is mixed and heated in the mixing chamber 26. If it continues, the temperature of the bath water 2 which circulates through the purification pipe line 14 and flows into the hot water temperature regulator 18 will continue to rise.
[0036]
Then, the flow rate adjusting valve 29 provided for the hot water inlet 20 of the hot water temperature adjuster 18 increases the temperature of the wax 33 which is a thermo element filled in the thermostat 32 and the volume expands to push the piston 34 upward. It becomes like this.
[0037]
However, since the upper end of the piston 34 is pressed by the holding shaft 36, the flow rate adjusting valve 29 starts to move downward in the direction of closing the valve, and the temperature of the bathtub 2 becomes the same as the temperature set by the bather, (B) A state as shown in FIG.
[0038]
That is, when the temperature of the bath water 2 rises and the flow control valve 29 continues to expand and lower the volume of the wax 33 of the thermostat 32, the valve cylinder 31 fitted in the valve hole 28 of the valve seat 27 of the mixing chamber 26 continues to lower, At the moment when the bath water 2 and the set temperature become the same, the lowering valve is closed until the lower end of the hot water closing tube 38 just reaches the position of the valve hole 28, and hot water does not enter from the hot water inlet 20.
[0039]
Then, the hot water 2 circulating in the cleaning pipe 14 does not flow in the direction of the hot water storage tank 22 after passing through the electric heater 7, but all flows in the direction of the hot water temperature controller 18. Is mixed and heated and returns to the bathtub 1 as it is.
[0040]
(B) As shown in the figure, when the valve of the flow rate adjustment valve 29 with respect to the hot water inlet 20 of the hot water temperature regulator 18 is closed and the bathtub hot water 2 is not heated and continues to circulate through the cleaning conduit 14, the temperature eventually decreases. put out.
[0041]
Then, since the volume of the wax 33 of the thermostat 32 starts to contract, the flow regulating valve 29 weakens the force to push the piston 34 upward, and rises upward. As for the valve cylinder 31, the hot water supply cylinder 39 enters the valve hole 28 of the valve seat 27. As shown in FIG. 5A, the hot water stored in the hot water storage tank 22 is mixed with the hot water temperature controller 18 in the bathtub hot water 2 circulating through the cleaning pipe 14. After being heated again, it returns to the bathtub 1.
[0042]
As described above, the hot water inlet 20 of the hot water temperature regulator 18 is used for the bathtub hot water 2 circulating through the cleaning conduit 14 while the hot water temperature is adjusted as described above. The valve of the flow rate control valve 29 provided for the valve is closed and does not become too high.
[0043]
However, even if the bath water 2 is heated too much for some reason and becomes higher than the set temperature, the flow rate control valve 29 for the hot water inlet 20 of the hot water temperature regulator 18 is peeled off as shown in FIG. The bath water 2 is completely closed, and the hot water is never mixed until the temperature is lower than the set temperature, and the temperature is never too high.
[0044]
That is, when the temperature of the bath water 2 becomes higher than the set temperature, the flow rate adjustment valve 29 of the hot water temperature regulator 18 continues to fall because the expansion of the wax of the thermostat 32 continues, and eventually the valve hole 28 of the valve seat 27 of the mixing chamber 26. Is closed by the upper end of the hot water closing cylinder 38 of the valve cylinder 31, and the valve is completely closed.
[0045]
When this happens, the bath water 2 continues to circulate through the cleaning line 14 without being heated, and the temperature gradually decreases. The flow rate control valve 29 of the hot water temperature regulator 18 contracts, the wax 33 of the thermostat 32 contracts, and the piston 34 The force that pushes upward weakens and gradually rises, eventually becomes the same as the set temperature (b), passes through the state shown in the figure, and then drops below the set temperature (a) The valve as shown in the figure again Until it is opened, the hot water stored in the hot water storage tank 22 is never heated.
[0046]
As described above, the hot water temperature adjuster 18 mixes hot water stored in the hot water storage tank 22 by closing the flow rate adjusting valve provided for the hot water inlet 20 at the same time as the temperature of the bath water becomes the same as the set temperature. Therefore, the bath water 2 is always at or below the set temperature, and is rarely too high.
[0047]
Even if the bath water 2 becomes higher than the set temperature, the flow control valve 29 moves in a direction to close the valve firmly as the temperature of the bath water rises, and never opens the valve until the temperature drops below the set temperature. During this time, hot water will be further mixed, and it will never be too hot so that there is a risk of burns.
[0048]
Moreover, the hot water temperature regulator 18 is provided in the state which provided the flow control valve 29 with respect to the hot water inflow port 20 in the middle of the purification pipe line 14 of the bathtub hot water 2, and the low temperature bathtub hot water 2 always flows in, Only when the temperature of the bath water 2 falls below the set temperature, the valve is opened and hot water stored in the hot water storage tank 22 is mixed to adjust the temperature of the bath water 2, so that the valve is broken. Even if hot water does not spout into the bathtub 1, it is safe.
[0049]
That is, when the flow rate control valve 29 breaks down and the valve remains closed, the hot water stored in the hot water storage tank 22 is not heated by mixing with the hot water stored in the hot water storage tank 22 and sprayed to the bathtub 1 in a state lower than the set temperature. There is no danger just by continuing, even if the valve remains open, it will always be in a state where the low temperature bath water 2 and hot water are mixed, so even if it becomes too hot, it will never burn you There is no danger that only the hot water stored in the hot water storage tank 22 is jetted into the bathtub 1 and burned, only the hot water 2 having a temperature at which there is no danger is jetted into the bathtub 1.
[0050]
If the flow rate adjustment valve 29 provided for the hot water inlet 20 of the hot water temperature regulator 18 is a thermostat type, the valve opens and closes depending on the temperature of the bath water 2 and is simply turned on at a predetermined temperature. Much more precise temperature control is possible than with a solenoid valve that simply turns off.
[0051]
The flow rate adjusting valve 29 may be configured to simply open and close the valve hole 28 with a valve plate. However, as shown in the embodiment, the valve cylinder 31 divided into a hot water supply cylinder 38 and a hot water supply pipe 39 is divided into valve holes. If it is configured such that it can be moved up and down to 28, the opening and closing of the valve becomes more precise and the temperature can be adjusted accurately.
[0052]
That is, when the temperature of the bath water 2 is too lower than the set temperature, the flow rate adjusting valve 29 is arranged so that the hot water supply tube 39 provided with the notch groove 40 as the hot water supply groove comes out on the valve seat 27 and opens the valve. However, the length of the hot water pipe 39 that is above the valve seat 27, that is, the amount of the hot water opening area that opens the valve, is changed according to the temperature of the bath water 2.
[0053]
For this reason, the hot water temperature adjuster 18 has an amount proportional to the temperature difference between the set temperature and the bath water 2 in the mixing chamber 26 when the bath water 2 is heated below the set temperature and the flow rate control valve 29 is opened. The hot water stored in the hot water storage tank 22 enters from the hot water inlet 20, and heats the bath water 2 quickly and accurately to the set hot water temperature.
[0054]
Moreover, since the valve is closed and hot water does not enter the mixing chamber 26 at the moment when the bath water 2 reaches the set temperature, the bath water 2 hardly reaches the set temperature.
[0055]
On the other hand, when the temperature of the bath water becomes higher than the set temperature and the flow rate control valve 29 is closed, the length of the hot water cylinder 38 that is exposed under the valve seat 27, that is, the amount of closing the valve, is also the same as the bath water 2 and the set temperature. If the bath water 2 is too higher than the set temperature, the valve will be completely closed as it is too high and never open until the bath water 2 falls below the set temperature. While accurately adjusting the temperature, the bath water 2 is completely prevented from becoming too hot.
[0056]
The flow rate adjusting valve provided for the hot water inlet 20 of the hot water temperature adjuster 18 is preferably one that operates based on the volume change according to the hot water temperature as shown in the above embodiment, but the shape memory alloy. It goes without saying that other types of valves may be used as long as the amount of opening can be changed according to the temperature of the bath water such as a formula.
[0057]
Further, in the thermostat type flow control valve, a material that changes in volume greatly in response to heat, such as a gas or a low melting point alloy other than wax, may be used as the thermo element.
[0058]
【The invention's effect】
The present invention is configured as described above, and the hot water temperature controller provided for mixing and heating the hot water stored in the hot water storage tank according to the hot water temperature is very simple in structure, low in cost and accurate. You can adjust the temperature.
[0059]
In addition, if hot water stored in the hot water storage tank is mixed with the hot water storage tank according to the hot water temperature in the middle of the cleaning line, the hot water stored in the hot water tank is mixed and heated. The bath water can be heated up to the set temperature rapidly.
