Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a whirlpool having a jet function for taking out bathtub water from a bathtub and returning it from a wall surface of the bathtub as a jet stream containing bubbles, and a filtering function for taking out bathtub water from the bathtub and filtering it. Regarding the unit.

[0002]

2. Description of the Related Art The applicant of the present application considers the fact that when a jet stream is sprayed on a bather, dirt or the like is likely to be removed and the bath water is easily soiled, before the bath water taken out from the bath is returned as a jet stream. We propose a whirlpool unit that is designed to be filtered.

[0003] There are also some which can carry out filtration independently.

[0004]

By the way, the applicant of the present application has also proposed an ozone sterilizer for purifying bath water and the like by using ozone, regardless of the above-mentioned function. It is more effective in purifying the water in the bathtub when used in the whirlpool unit. In order to achieve this, at present, jet sterilization equipment is used.
It must be installed separately from the filtration device, and it is desired to combine the ozone sterilization function and the jet / filtration function without waste and without any functional problem.

In view of the above circumstances, the present invention provides a structure capable of efficiently purifying bath water by combining the ozone sterilization function and the jet / filtration function without waste and without functional problems. This is an issue.

[0006]

The present invention has a jet function of taking out bath water from a bathtub and returning it from the wall surface of the bathtub as a jet stream containing bubbles, and a filtering function of taking out bathwater from the bathtub and filtering it. The whirlpool unit is configured as follows.

The whirlpool unit of the present invention comprises a circulation water channel for jetting and filtering for taking out the bath water and then returning it, a circulation water channel for sterilization connected in parallel with this circulation water channel, and a connecting portion between both water channels. An on-off valve for connecting or blocking both water channels, a first circulation pump and a filter provided in the middle of the jet / filtration circulation channel, an ozone reaction chamber and a second in the middle of the sterilization circulation channel. A circulation pump and a control means for controlling each of the above elements to execute a jet function, a filtration function, or an ozone sterilization function in response to a request are provided.

[0008]

[Function] By connecting the circulation water passage for sterilization to the circulation water passage for jet / filtration, the jet / filtration mechanism and the ozone sterilization mechanism are combined, and a set of bath water take-out port and reflux port is provided in the bathtub. It does not need two sets as in the case of making them separate. Further, by the opening / closing valve, the ozone / sterilization function can be executed when the jet / filtration circulation water channel and the sterilization circulation water channel are in communication with each other, and the jet function and the filtration function can be executed when they are cut off.

[0009]

FIG. 1 shows an embodiment of the present invention. In summary, the whirlpool unit of this embodiment can perform ozone sterilization in addition to filtering the bath water in consideration of the fact that the jet spout easily removes dirt from the bather and the bath water is easily soiled. Is configured.
In the figure, A is a jet / filtration mechanism part, B is an ozone sterilization mechanism part, and C is a controller as a control means.

The jet / filtering mechanism A has a main circulation water passage (outlet pipe, return pipe) 10 connecting the suction port 4 provided in the bathtub 2 with the jet nozzles 6, 8 on the back side and the foot side,
A first circulation pump 12 provided in the middle of the main circulation water passage 10 for circulating bath water, and water amount adjusting valves 14, 1 provided on the discharge side of the first circulation pump 12 in the main circulation water passage 10.
6 and an air suction pipe 1 connected to the jet nozzles 6 and 8
8, the air amount adjusting valve 20 provided on the suction end side of the air suction pipe 18, and the first circulation pump 1 in the main circulation water passage 10.
First auxiliary circulating water channel 2 connected to the suction side and the discharge side of
2, a steam separation tank 24 provided in the middle of the first auxiliary circulation water passage 22, and a filter 26 containing a fluid filter medium.
And three-way switching valves 28 and 30 provided at the connection between the main circulation water passage 10 and the first auxiliary circulation water passage 22. The air / water separation tank 24 and the filter 26 are provided with air bleeding valves 32 and 34 with check valves.

The ozone sterilization mechanism section B includes a second auxiliary circulating water passage 36 connected in parallel with the main circulating water passage 10 and the second auxiliary circulating water passage 36.
The second circulation pump 3 provided in the middle of the auxiliary circulation water passage 36
8 and the ozone reaction chamber 40, the ozone supply device 42 for supplying the ozone reaction chamber 40 with ozonized air (having a proper concentration of ozone mixed with air), and the intake section of the second auxiliary circulation water channel 36. And on-off valves 44 and 46 provided in the reflux section. In the ozone reaction chamber 40, ozonized air is previously taken in, and then bath water is introduced, and this is dispersed in a shower shape by the mesh sheet 48 above the inside so as to contact with ozone. An ejector 50 is provided on the front side of the ozone reaction chamber 40 where the bath water is introduced. The ejector 50 sucks the ozonized air in the reaction chamber and mixes it with the bath water to form the ozone reaction chamber 4.
It is designed to drop to 0. Second auxiliary circulation channel 3
The intake portion 6 is connected to the outlet side of the filter 26 in the first auxiliary circulation water passage 22, and the return portion is connected to the downstream side of the air amount adjusting valve 20 in the air suction pipe 18. Reference numeral 52 is a purge valve.

The controller C controls each of the above elements in accordance with a user's request to execute a jet function, a filtration function and an ozone sterilization function. Although not shown, the controller C includes a jet switch for instructing execution of a jet function, a sterilization switch for instructing execution of an ozone sterilization function, a filtration switch for instructing execution of a single filtration function, a jet ejection strength and air bubble mixture. And an intensity switch for specifying the quantity.

Next, the operation will be described.

(1) When the jet switch is operated, the flow paths are set by the three-way switching valves 28 and 30 so that the bath water flows in the direction of the solid line arrow in the figure, and the on-off valve 4
4 and 46 are set to “closed”, and the water amount adjusting valves 14 and 16 and the air amount adjusting valve 20 are set to any one of three stages of weak, medium and strong according to a request (switch not shown). Then, the first circulation pump 12 is driven. This allows
While the bathtub water in the bathtub 2 is taken out from the suction port 4, a part of the bathtub water from the discharge side of the first circulation pump 12 is passed through the filter 26 from the forward direction to the first auxiliary circulation water passage 22 and filtered, Most of the remaining bath water is returned to the bath 2 through the jet nozzles 6 and 8. The air suction pipe 1 by this reflux water
Since the inside of 8 is in a negative pressure state, the air sucked through the air suction pipe 18 is supplied to the jet nozzles 6, 8 where the reflux water and the air are mixed to form a foam and the bathtub 2
A jet is jetted out. The bubbles contained in the bath water taken into the first auxiliary circulation water passage 22 are discharged to the outside from the air bleed valves 32 and 34 with check valves provided in both the steam separation tank 24 and the filter 26. .

When the jet operation including such filtration has passed for a predetermined time, the jet operation is temporarily interrupted and the bath water is passed through the filter 26 in the direction opposite to that at the time of the filtration so that the filter 26 can be operated.
A backwashing process is performed to wash the. During this backwash process,
The flow paths are changed by the three-way switching valves 28 and 30 so that the bath water flows in the direction of the broken arrow in the figure. This backwashing process is continued for a predetermined time, then terminated, and the jet operation is resumed.

When the jet switch is operated again or the operation is stopped due to the time-out of the built-in timer (not shown) of the controller C, the first circulation pump 12 is stopped and the air amount control valve is stopped. Only 20 is "closed" and other valves are maintained as they are.

(2) When the filtration switch is operated, it is almost the same as the above-mentioned jet operation condition, but the only difference is that the air amount adjusting valve 20 is "closed" and the bath water is recirculated. This is to prevent air from being mixed with the jet nozzles 6 and 8. The single filtration operation is mainly
This is done for the next bather. When nothing is operated, the air amount control valve 20 is “closed”, so at the start of this filtering operation, the air amount control valve 20 is closed.
There is no need to control the.

(3) When the sterilization switch is operated, the flow paths are set by the three-way switching valves 28 and 30 so that the bath water flows in the direction of the two-dot chain line arrow in the figure, and the on-off valve 4
4, 46 are "opened" and the water amount adjusting valves 14, 16 are "closed" to drive the second circulation pump 38 and the ozone supplier 42. As a result, most of the bath water taken out of the bath 2 flows in a short circuit to the water passage connecting the suction side of the first circulation pump 12 and the outlet side of the filter 26 which are not driven due to the water passage resistance. Then, it is introduced into the ozone reaction chamber 40 of the second auxiliary circulation water channel 36. This ozone reaction chamber 4
The bath water is sterilized at 0 and then returned to the air intake pipe 18,
It is returned to the bathtub 2 through the jet nozzles 6 and 8. The ozone reaction chamber 40 is for sterilizing the bath water by contact-mixing the introduced predetermined amount of ozone with the continuously introduced bath water, and the purge valve 52 is turned on after a predetermined time elapses. Open it and let it evacuate before introducing new ozone. This is repeated the required number of times.

When the sterilization switch is operated again or the operation is stopped due to the timer being timed up, the second circulation pump 38 and the ozone supplier 32 are stopped, and the on-off valves 44 and 46 are also stopped. Is closed, and other valves are maintained as is.

By the way, during the above-mentioned ozone sterilization operation, since only the second circulation pump 38 is driven, the insides of the steam / water separation tank 24 and the filter 26 are in a negative pressure state. Since the check valves 32 and 34 are provided with check valves, the outside air is not sucked from the air check valves 32 and 34, and bubbles are not mixed in the bath water introduced into the second auxiliary circulation water passage 36. When the first circulation pump 12 is also driven during the ozone sterilization operation, the suction force of the first circulation pump 12 acts on the outlet of the filter 26,
Since it is considered that the amount of bath water introduced into the second auxiliary circulation water passage 36 may decrease, it is preferable to set the first circulation pump 12 not to be driven during the ozone sterilization operation. Furthermore, if an on-off valve is provided in the water path from the outlet of the filter 26 to the suction side of the first circulation pump 12, and this on-off valve is closed during ozone sterilization operation, all of the bath water taken out of the bath 2 will be removed. It can be introduced from the discharge side of the driven first circulation pump 12 into the first auxiliary circulation water passage 22, and can be guided to the second auxiliary circulation water passage 36 after being filtered by the filter 26.

The present invention is not limited to the above embodiment. For example, the reflux portion of the second auxiliary circulation water passage 36 may be connected to the discharge side of the first circulation pump 12 in the main circulation water passage 10. When this connection is set on the upstream side of the water amount adjusting valves 14 and 16, the water amount adjusting valves 14 and 16 during the sterilization process are performed.
Is set to "open", and when the connecting portion is set to the downstream side of the water amount adjusting valves 14 and 16, the water amount adjusting valve 14 and
It is preferable to control 16 to be “closed” to increase the stirring action in the bath 2 associated with the circulation of the sterilized bath water so that the bath water can be efficiently replaced.

[0022]

As described above, according to the present invention, the jet function or filtration function mechanism section and the ozone sterilization function mechanism section are made as common as possible so that they can be combined without waste and functionally. Therefore, it is possible to efficiently purify the bath water that is easily polluted by jetting.
