DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating and filtering apparatus for bathtub water, which circulates bathtub water and purifies it using a filter material.

[0002]

2. Description of the Related Art Conventional bath tub water circulating and filtering devices are known as inns,
It is for business use used in large baths, open-air baths, heated pools, etc. in hotels, etc., and the hot water supplied to the bath tub is controlled to the appropriate temperature and surface level at any time by setting a timer, and this bath tub water is passed through a filtration device. It is clean and ready to take a bath at any time. In this bath water circulation filter,
There is no need to replace the bathtub water with fresh water every day for cleaning, so that there is an advantage that the cost of water supply and heating fuel can be saved.

FIG. 1 shows the above-mentioned conventional circulating filter for bath water. The bathtub water is filtered from the bottom of the bathtub 41 by a filtration pump 44.
And removes hair and foreign matter through the hair catcher 43. The hair catcher 43 has a built-in synthetic resin bucket.

[0004] Bath water passed through the hair catcher 43 is sent to a filtration filter device 45 by a filtration pump 44, and is filtered by an internal filter to be purified. The purified bath water then enters a three-way valve 46, and the temperature sensor 48 provided at the rear end of the pipe detects the inflow temperature into the bath 41, which is the temperature of the hot water supplied to the bath 41. The signal is received by the electronic thermo in the control panel 49 and the three-way valve 4
6 is controlled. If the inflow temperature of the bathtub 41 is an appropriate temperature, the three-way heating valve 46 opens the upper bypass line in FIG.
If the inflow temperature of the bathtub 41 is low, the lower heating pipe in the figure is opened widely and the heating device 47 heats. That is, bathtub 4
In the case where the temperature 1 is lower than the electronic thermo set temperature, for example, 40 ° C., the three-way heating valve 46 is operated so as to increase the inflow amount to the heating device 47 side, and the temperature detected by the temperature sensor 48 becomes the electronic thermo set temperature. Is adjusted proportionally so as to approach. The level of the bath surface of the bathtub 41 is the same as the level of the bath surface of the bathtub 41 in the level gauge 50, and the level is adjusted to the level of the level provided in the level gauge 50. If the level is detected by a plurality of different electrode rods and the level is low, the control panel 49 opens and closes the supply water valve 51 to supply water to control the level of the level.

[0005] In recent bathing facilities, various types of small-capacity bathtubs such as jet baths, bubble baths, electric baths, hot water pools, and hot water pools are preferred and mixed. For this reason, a filtering device is required for each, and a plurality of filtering devices corresponding to the number of filtering devices are required. However, on the other hand,
In order to reduce equipment costs, it is required to reduce initial costs and reduce installation space. Furthermore, there is a difference in the temperature of hot water that can be bathed comfortably depending on the gender age and preference, and therefore, a device that can adjust the hot water temperature to a different temperature for each bathtub is required.

Furthermore, even if a plurality of bathtubs are installed on different floors such as a nursing home, or bathtubs of different sizes are installed, or even if they are on the same floor and at the same horizontal level, In the case where the distance between the plurality of bathtubs is large, or in the case of a plurality of bathtubs having different bathtub water temperatures, bathtub water is supplied to these bathtubs by separate circulation filtration devices. However, in order to reduce costs, it is required that one circulating filtration device be controlled to a suitable temperature and a suitable surface level.

Therefore, as shown in FIG. 2, in the case of two bathtubs 41a and 41b at the same horizontal level, the bathtub 4
1a and the bathtub 41b are connected by a communication pipe 42, and are circulated and filtered by one filtration circulating device. That is, bathtub 4
1a and a bathtub 41b are connected by a communication pipe 42, and bathtub water is filtered from a bottom of the bathtub 41a and the bathtub 41b by a filtration pump 44.
And removes hair and foreign matter through a hair catcher 43 containing a synthetic resin bucket.
The bath water passed through the hair catcher 43 is filtered by a filtration pump 44.
Is sent to the filtration filter device 45, and is filtered and purified by the built-in filter. The purified bathtub water then enters a three-way valve 46 for temperature rise, and a temperature sensor 48 provided at the rear end of the pipeline detects a bathtub forward temperature to be supplied to each of the bathtubs 41a and 41b. The temperature rise three-way valve 46 is controlled by receiving the electronic thermo of the control panel 49. That is, the temperature rise three-way valve 46 is proportionally adjusted by the electronic thermometer of the control panel 49, and when the bathtub outgoing temperature is an appropriate temperature, the temperature rise three-way valve 46 closes the pipe on the heating device 47 side and opens the other pipe. If the bathtub outgoing temperature is low, the pipe on the heating device 47 side is opened and the other pipe is closed, and the heating device 47 heats. The bath level of the bathtub 41a and the bathtub 41b is detected by detecting the level of the bath surface of the one bathtub 41a with electrode rods having different lengths provided in the water level gauge 50, and the bath surface is reduced by being used as hot water. If it is, the control panel 49 opens and closes the make-up water valve 51 to supply water and is controlled to be constant. However, bathtub 41a
When the distance between the bathtub 41b and the bathtub 41b is large, a communication pipe 42 having a diameter area twice or more the diameter area of the circulation path is required.

However, as described above, when the plurality of bathtubs are different in size or are not on the same horizontal plane but are provided on different floors, the bath level of each bathtub is different. If the tubs are connected to the same pipeline, there will be a difference in water pressure between the bathtubs on different floors, and it will not be possible to circulate and supply the hot water level in each bathtub to the same level with one circulating filtration device. Was.

That is, a water level control valve 18 and a flow control valve 19, which are motor valves controlled by the control panel 14, are provided in one of the high-pipe pipes, and a bypass flow control valve 20 is provided in the other pipe. Then, these pipes are united and passed through a circulation flow meter valve 24 to serve as a high-level-side level control unit. Similarly, a water level control valve 21 composed of a motor valve controlled by the control panel 14 and a flow control valve 35 are provided in one of the pipes after the water-fall prevention electromagnetic valve 29 in the low-place pipe, and a bypass is provided in the other pipe. A flow control valve 22 is provided, and these pipes are united and passed through a circulating flow meter valve 23 to serve as a low-level side level control unit.

In the above-mentioned means, a high-altitude bathtub 26
As shown in FIG. 4, the hot water level of the low-level bathtub 1 is divided into an upper level A and a lower level B of an appropriate level and an upper level C and a lower level D of a dangerous level. The levels are detected by the water level gauge 27 and the water level gauge 10, and based on the detection results, the control panel 14 opens and closes the make-up water valve 11 disposed in the pipeline of the purification means, and detects the level of the filtration pump 3.
The control means controls the restart and stop of the operation and controls the level control valve 18 and level control valve 21 in the level control means.

Next, the operation of controlling the level of the molten metal and the operation procedure of the apparatus according to the first embodiment will be described. First, in FIG. 3, when all the switches of the control panel 14 are automatically set, the bath surfaces of the bathtub 1 and the bathtub 26 are low,
Since it is below 0 and the level D of the level gauge 27 (see FIG. 4), the filtration pump 3 is stopped. Since the water level gauge 10 in the bathtub 1 and the water level gauge 27 in the bathtub 26 are below the B level, the make-up water valve 11 is opened. The water replenished from the make-up water valve 11 is supplied to the filtration pump 3 and branched by the temperature raising three-way valve 13, one of which is heated by the heating device 5, and the other is mixed with the water from the bypass line 8. The outlet temperature is detected by the temperature sensor 9, the amount of branch water is adjusted by the control panel 14 by the temperature raising three-way valve 13, and the hot water temperature is controlled to the prescribed hot water temperature of the bathtub. Hot water that has passed through the temperature sensor 9 flows into the high-altitude side pipe since the water-fall prevention valve 29 is closed because the filtration pump 3 is stopped. One passes through the bypass flow rate control valve 20 and the other passes through the level control valve 18 and the flow rate control valve 19, and the two pass together and pass through the circulation flow meter valve 24, and are sent to the bathtub 26 on the high side. The level of the bathtub 26 is level gauge C
, The filtration pump 3 starts operating, and at the same time, the water-fall prevention valve 29 is opened to be fed also to the low-side pipe, and then to the bathtub 1 via the pipe 6.

When the level of the bathtub 26 or the bathtub 1 reaches the level A in FIG. 4 as described above, the level is detected by the level gauge 27 or the level gauge 10 and controlled by the control panel 14 to control the make-up water valve. 11 is closed and the level control valve 1 which has reached further
8 or the level control valve 21 is closed. For example, when the bathtub 1 rises quickly and the bathtub 1 reaches the A level, the bath level control valve 21 is closed, and only the throttled hot water is supplied from the bypass flow control valve 22. As a result of the level control valve 21 being closed, the level of the bath level in the bathtub 1 gradually decreases and the level gauge 10 falls below the level B, the level control valve 21 opens and the level gradually rises again. I do. The bathtub 26 repeats the same operation as the bathtub 1. Therefore, each molten metal surface is held between A and B. Bath tub 26 or bath tub 1 depending on use
When the level of the water level decreases and both the level of the level gauge 27 and the level of the level gauge 10 become equal to or lower than the B level, the replenishment water valve 11 is opened by the control from the control panel 14, and the replenishment lamp provided separately is lit. Then, when either the level gauge 27 or the level gauge 10 reaches the A level, the makeup water valve 11 is closed.

If the level of either the bathtub 26 or the bathtub 1 drops and the level of the level gauge 27 or the level gauge 10 falls below the D level, a separately provided drought lamp is turned on. When the temperatures of both the bath tub 26 and the bath tub 1 become lower than the D level, a separately provided drought buzzer sounds and the filtration pump 3 is stopped. When the surface of either the bathtub 26 or the bathtub 1 is restored to the C level, the operation of the filtration pump 3 is restarted. When the operation of the filtration pump 3 is stopped as described above, the water-fall prevention solenoid valve 29 is closed, and the check valve 17 prevents water from flowing from the bathtub 26 at a high place to the bathtub 1.

Further, the temperature control operation and operation procedure of the bathtub 26 and the bathtub 1 having different hot water temperature set temperatures of the apparatus according to the second embodiment will be described. It should be noted that the control operation and the operation procedure of the liquid level control in the apparatus according to the second embodiment are the same as the control operation and the operation procedure of the apparatus according to the first embodiment, and the description thereof will be omitted. if,
When the bath temperature of the bathtub 1 is lower than the set temperature of the electronic thermostat for the bathtub 1 separately provided on the control panel 14, for example, 40 ° C., FIG.
In the apparatus shown in FIG. 3, the temperature of the outlet of the temperature sensor 30b is detected, the electronic thermo of the control panel 14 is operated to activate the three-way heating valve 13 which is the hot water temperature control means on the bathtub 1 side, and the heating device 5
As a result, the temperature of the hot water detected by the temperature sensor 30b increases because the amount of hot water coming from the heating device 5 increases.
When the detected temperature of 0b reaches 40 ° C., the three-way valve 13 is adjusted to increase the amount of hot water in the bypass pipe 32 as compared with the heating device 5 side, and the outlet temperature of the temperature sensor 30b becomes 40 ° C.
Is controlled to be maintained at

Similarly, if the set bath temperature of the bathtub 26 is controlled to be lower than the set bath temperature of 38.degree.
The three-way heating valve 38 in the hot water temperature control means on the side is operated by the temperature sensor 30a from the electronic thermostat for the bath tub 26 of the control panel 14 to the heating three-way valve 38 as the hot water temperature control means on the bath tub 26 side. As a result, the temperature of the hot water detected by the temperature sensor 30a increases because the amount of hot water coming from the heating device 5 increases, and the temperature detected by the temperature sensor 30a becomes 38. ℃,
The temperature rise three-way valve 13 is adjusted to increase the amount of hot water in the bypass conduit 31 as compared with the heating device 5 side.
Is controlled such that the outlet temperature is maintained at 38 ° C.

As shown in FIG. 6, an operation test was performed on an actual machine. A 1500 liter bathtub 26 and a water level gauge 27 are installed on the roof of a factory on the fourth floor, and a 60

Start driving.

The flow control valve 19 and the flow control valve 35 are closed, the flow rate of the pipe 25 of the bathtub 26 is set to 50 liters per minute by the circulation flow meter control valve 24, and the bathtub 1 is controlled by the circulation flow meter control valve 23. Is set to 20 liters per minute. In general, this setting is based on the fact that if the bath is circulated twice as much as the amount of hot water in the bath for one hour, the filtration body can properly purify the water. In this state, the level of the bath surface of the bathtub 1 on the second floor is adjusted by the bypass flow rate control valve 22 so as to gradually decrease. Then, the level control valve 21 is manually opened and adjusted by the flow rate control valve 35. Then, adjustment was performed so that the surface of the bathtub 1 gradually rose. Similarly, the level of the hot water in the bathtub 26 on the roof is adjusted by the bypass flow rate adjusting valve 20 so as to gradually decrease, and then the hot water level control valve 18 is manually opened.
The adjustment was performed by the flow control valve 19 so that the surface of the bathtub 26 gradually rose.

After the above adjustments, a running test was conducted for 6 days a day for 5 days. Both bath tubs 26 and bath tubs 1 had a level of 20 m between levels A and B shown in FIG.
m, the replenishing water valve 11 was opened when both bathtubs fell below the level B, and the refilling water valve 11 was closed when either of the bath surfaces reached the level A. Makeup water valve 11
