The first feature is that the sub-circulation path is further provided with an ozone inlet and a reaction tower for the introduced ozone and the sub-circulation water.

Further, the bathtub water sterilization and purification device of the present invention has a main circulation path for a one-pack bath connected to the bathtub, and a main VV provided in the cough main circulation path.
& A bathtub water sterilization and purification device having a ring pump and a sub-circulation path branching from the main circulation path and connecting the flow to the main circulation path via a filter, the sub-circulation path including the filter. In addition, a sub-circulation pump exclusively for sub-circulation, an ozone inlet, and a reaction tower for ozone and sub-circulation water are provided, and the branch port and connection port of the sub-circulation path discharge the main circulation path into the bathtub. The second feature is that check valves are provided upstream and downstream of the passageway.

Further, in the bathtub water sterilization and purification device of the present invention, in the second feature, the branch port and the connection port of the subcirculation path are provided in the main circulation path of the main circulation path, instead of being provided in the discharge path to the bathtub of the main circulation path. The third feature is that a check valve is provided in the suction path upstream and downstream of the suction path.

<Operation> According to the first feature of the device of the present invention, the main circulation bomb is driven to introduce part of the bath water into the sub-circulation path while introducing ozone into the sub-circulation path, thereby achieving filtration. In addition to the purification of bath water by the device, bath water can also be sterilized by the ozone reaction tower. Sterilization and purification of bathtub water can be performed while operating a bubble bath.

According to the second feature of the device of the present invention, even if only the auxiliary circulation pump provided in the auxiliary circulation path is driven, bath water flows from the bathtub to the main circulation path through the suction path and the main circulation pump to the main circulation path. The water enters the discharge path, is further guided from the branch port to the subcirculation path, passes through a filter and an ozone reaction tower, enters the discharge path again from the connection port at the end of the subcirculation path, and travels backward through the discharge path using a check valve.

After passing through a filter and an ozone reaction tower, it enters the suction path again from the connection port at the end of the subcirculation path, and is prevented from flowing backward through the suction path by the reverse valve, allowing it to pass through the main circulation pump and discharge path. The water is then circulated to the bathtub. That is, bath water can be sterilized and purified economically without using a main circulation pump. In addition, when sterilizing and purifying at the same time during bath operation using a main circulation bomb, the connection port at the end of the subcirculation path is connected to the suction path, which lowers the internal pressure of the GLL circulation path, making it necessary to introduce ozone at high pressure. It can be easily installed using the ejector method.

Example FIG. 1 is a block diagram showing a first embodiment of the apparatus of the present invention.

A main circulation path 20 for a bubble bath is connected to the bathtub 10,
A main circulation pump 30 is provided in the main circulation path 20 . The main circulation path 20 includes a suction path 21 from the bathtub 10 to the main circulation bomb 30 and a discharge path 22 from the main circulation bomb 30 to the bathtub 10. At the end of the discharge passage 22, the bathtub 10
An ejector 42 is configured at the connection part to the ejector 42, and an air introduction pipe 40 is connected to the negative pressure forming part of the ejector 42 via a valve 4l.
is connected. When performing a bubble bath operation, the main circulation pump 30 may be driven and the valve 41 may be opened. The high flow rate by the main circulation pump 30 draws air from the ejector 42 and ejects a stream of bubbles into the bathtub IO.

The sub-circulation path 50 is branched from the discharge path 22 of the main circulation path 20 and connects its flow to the suction path 21 of the main circulation path 20 through a filter 60 . 51 is a bypass of the subcirculation path 50;
52 is a discharge path from the sub-circulation path 50. Also V1■2
is a three-way valve.

70 is an ozone 'tX (ozone generator), and the ozone source 7
An ozone introduction pipe 71 is connected to the filter 60 of the subcirculation path 50 or the bypass 5 through an on-off valve 72.
1 at a downstream position. A reaction tower 74 is provided further downstream of the ozone inlet 73. The ozone introduced into the sub-circulation path 50 sufficiently contacts and reacts with the sub-circulation water in the reaction tower 74, thereby sterilizing the sub-circulation water.

The reacted gas is then discharged from the gas vent valve 75.

To filter and sterilize the bathtub water, the main circulation pump 30 is driven, and a part of the circulating water circulating through the main circulation path 20 is circulated through the sub-circulation path 50 in the direction of the solid line arrow in FIG. This is done by opening the on-off valve 72 of 71. The bathtub water that enters the subcirculation path 50 from the discharge path 22 is filtered by the filter 60 and further sterilized by the reaction tube 74, then returns to the suction path 21, passes through the main circulation bomb 30 and the discharge path 22, and enters the bathtub. return.

When backwashing the filter 60, the three-way valve ■1, v
2, the main circulation bomb 30 is driven to guide the bathtub water into the subcirculation path 50 in the direction of the broken line arrow in FIG.
After backwashing the 0, it is discharged to the outside from the discharge path 52. During this backwash operation, the ozone inlet 73 becomes under negative pressure, so the on-off valve 72 is required.

FIG. 2 is a block diagram of main parts showing a second embodiment of the device of the present invention.

This example has a configuration in which one three-way valve V2 is omitted from the apparatus of the first embodiment described above, and the on-off valve 72 is removed from the ozone introduction pipe 71. The rest of the structure is the same as the device of the first embodiment, and the same members are denoted by the same reference numerals.

In the device of the second embodiment, when bath water is filtered and sterilized by the sub-circulation path 50, some of the sub-circulation water passes through the bypass 51 without passing through the filter 60. In addition to backwashing the filter 60, it is also circulated in the direction of the reaction column 74, as shown by the dashed arrow in FIG.

Therefore, by introducing ozone, sterilization operation can be performed even during backwashing. Further, since the inside of the ozone introduction pipe 71 does not become negative pressure even during backwash operation, the on-off valve 72 in the first embodiment is not necessary, nor is a check valve required.

FIG. 3 is an overall configuration diagram showing a third embodiment of the device of the present invention. In this embodiment, the ozone inlet 73 and the reaction tower 74 are
is provided downstream of the filter 60 in the subcirculation path 50 and upstream of the bypass 51 by the three-way valve (2).

Further, the ozone introduction pipe 71 is provided with a check valve 76 instead of the on-off valve 72 in the first embodiment. The other configurations are similar to those of the first embodiment already described, and the same members are given the same reference numerals. In this embodiment, during filtration and sterilization operations, subcirculation water flows through the subcirculation path 50 in the direction shown by the solid arrow in FIG. 3, and is filtered by the filter 60 and sterilized by the reaction tower 74. In this case, since the three-way valve 2 is provided downstream from the reaction tower 74, the ozone inlet 73
The ejector effect becomes weaker. On the other hand, the filter 60
During backwashing, the backwash water flows as shown by the dashed arrow in Figure 3.
Since the flow backs into the reaction tower 74, the inside of the ozone introduction pipe 71 does not become a negative pressure, but becomes a pressurized state, so the on-off valve 72 as in the case of the first embodiment is not necessary, and the check valve 76 is sufficient. becomes.

FIG. 4 is a configuration diagram of the main parts showing a fourth embodiment of the device of the present invention. This embodiment is obtained by omitting the three-way valve (2) from the third embodiment shown in FIG. The other configurations are similar to those of the third embodiment, and the same members are given the same reference numerals. In this embodiment, the three-way valve V2 can be omitted, but a flow that does not pass through the filter 60 or the reaction tower 74 occurs in both the filtration and sterilization operation and the backwash operation.

The first to fourth embodiments described above constitute one inventive concept.

FIG. 5 is an overall configuration diagram showing a fifth embodiment of the device of the present invention. In this embodiment, the subcirculation path 50 is provided with a subcirculation pump 80 exclusively for subcirculation. This auxiliary circulation pump 80 may have a smaller capacity than the main circulation bomb 30. Further, a branch port 53 from the main circulation path 20 of the sub-circulation path 50 is provided in the discharge path 22, and a connection port 54 of the sub-circulation path 50 to the main circulation path 20 is also provided from the branch port 53 of the discharge path 22. It is provided on the downstream side via a reverse valve CI. Further, a check valve 76 is provided in the ozone introduction pipe 7l instead of the on-off valve 72. Other than this, the configuration is the same as that of the first embodiment shown in FIG. 1 above. Identical members are indicated by the same reference numerals. In the case of this embodiment, the auxiliary circulation pump 80 can be used not only when the main circulation pump 30 is driven, but also when the main circulation pump 30 is not driven.
Filtration and sterilization operations can be performed by driving the . That is, when the auxiliary circulation pump 80 is driven, the bathtub water passes through the suction path 21, the main circulation pump 3Q (in a stopped state),
A part of the discharge passage 22 enters the subcirculation passage 50 through the branch port 53, circulates in the direction shown by the solid line arrow in FIG. will be held. The sub-circulating water then enters the discharge passage 22 again from the terminal connection port 54 and is led to the bathtub 10. If the check valve C is not provided, water entering the discharge passage 22 from the connection port 54 will not be guided to the bathtub 10 side.

Backwashing can also be performed by independently driving the auxiliary circulation pump 80. In this case, by switching the three-way valve 2, the bathtub water flows through the auxiliary circulation path 50 as shown by the broken line arrow in Figure 5, and after backwashing is performed, it is discharged to the outside of the system from the discharge path 52. be done. Note that since positive pressure is applied to the ozone introduction pipe 71, a check valve 76 is required. Further, when the main circulation bomb 30 is driven to introduce ozone during a bubble bath operation, it is necessary to introduce ozone into the subcirculation path 50 using a suitable high-pressure combustor.

FIG. 6 is an overall configuration diagram showing a sixth embodiment of the device of the present invention. In this embodiment, the ozone inlet 73 and the reaction tower 74 are
is provided downstream of the filter 60 in the subcirculation path 50 and upstream of the three-way valve v2 of the bypass 51. The other configurations are the same as the fifth embodiment shown in FIG. The same members are given the same symbols. During filtration and sterilization operations, the auxiliary circulation path 50 is circulated in the direction of the solid line arrow in FIG. Further, during backwash operation of the filter 60, bath water flows in the direction of the dashed arrow in FIG. 6 and is discharged from the discharge passage 52.

Note that the three-way valve 52 of the bypass 51 can be omitted in the fifth embodiment and the sixth embodiment as well.

The fifth embodiment, the sixth embodiment, and those in which the three-way valve 52 is omitted constitute one inventive concept.

As shown in FIG. 7, instead of the check valve C1 in FIGS. 5 and 6, the branch port 53 of the auxiliary circulation path 50 may be a three-way valve 3 (seventh embodiment). In this case, bubble bath operation and filtration sterilization operation cannot be performed at the same time.

FIG. 8 shows an eighth embodiment of the device of the present invention. In this embodiment, the branch port 53 of the subcirculation path 50 is connected to the suction path 2 of the main circulation path 20.
1, and the connection port 54 of the subcirculation path 50 is also provided downstream of the branch port 53 of the suction path 21 via a check valve Ct. Further, a sub-circulation bomb 80 exclusively for sub-circulation is provided in the sub-circulation path 50. Other than this, the configuration is the same as the first embodiment shown in FIG. Identical members are given the same reference numerals. In the case of this embodiment, filtration and sterilization operations can be performed not only by driving the main circulation bomb 30 but also by simply driving the auxiliary circulation pump. That is, when the sub-circulation pump 80 is driven, the bathtub water flows from the suction path 2l to the branch port 53.
It enters the auxiliary circulation path 50 through the pipe, circulates in the direction shown by the solid line arrow in FIG. 8, and is filtered by the filter 60 and sterilized in the reaction tower 74. Then, it enters the suction path 21 again through the terminal connection port 54 and is led to the bathtub 10 via the main circulation pump 30 and the discharge path 22. If the check valve C2 is not provided, water entering the suction path 21 from the connection port 54 will flow toward the branch port 53 side.

Backwashing can also be performed by independently driving the auxiliary circulation pump 80. In this case, by switching the three-way valves V1 and 2, the bathtub water is caused to flow in the direction of the dashed arrow in FIG. in this case,
As in the case of the first embodiment shown in FIG. 1, since negative pressure is applied to the ozone introduction pipe 71 during backwashing, a check valve is not sufficient and an on-off valve is required.

On the other hand, when the main circulation bomb 30 is driven and ozone is introduced during bubble bath operation for filtration and sterilization, unlike the embodiments shown in FIGS. 5 and 6, a high-pressure compressor is used to introduce ozone. Ozone can be introduced using the ejector effect without the need for ozone.

Note that in the eighth embodiment, the three-way valve vz of the bypass 51 can be omitted. In this case, the water flow during the filtration sterilization operation and backwashing in the subcirculation path 50 is changed to the second flow shown in FIG.
This is the same as in the embodiment, and for the same reason, the on-off valve 72 and check valve 7G are not required in the ozone introduction pipe 71.

FIG. 9 is an overall configuration diagram showing a ninth embodiment of the device of the present invention. In this embodiment, the ozone inlet 73 and the reaction tower 74 are located downstream of the filter 60 in the subcirculation path 50, and the high bus 5
Three-way valve 1 is installed on the upstream side of 2. The structure of the pond is the same as that of the eighth column except that the valve of the ozone introduction pipe 71 may be a check valve 76.
This is the same as the eighth embodiment shown in the figure. Identical members are given the same reference numerals. During filtration and sterilization operation, the auxiliary circulation path 50 is circulated in the direction of the solid line arrow in FIG. Further, during backwash operation, bathtub water flows in the direction of the broken line arrow in FIG.

Incidentally, also in the ninth embodiment shown in FIG.
The three-way valve 52 can be omitted.

Effects> The present invention has the above configuration, and according to the bathtub water sterilization and purification device according to claim 1, by driving the main circulation pump, the bathtub water can be sterilized and purified at the same time while performing a bubble bath operation. It can be carried out. Therefore, in a bubble bath device where bacteria are likely to breed, the cleanliness of the bathtub water can be maintained and the bathtub water can be made to last for a long time.
