Abstract

PURPOSE:To prevent counterflow of the circulative water toward an ozone generator by furnishing a buffer time between the bubble bath operation and ozone pasteurizing operation. CONSTITUTION:When a bubble bath operation switch is turned off, a circulation pump 3 stops, but a certain period is needed until complete stop is attained, and meantime the pump 3 continues inertia motion. Accordingly start of driving an ozone pasteurizing pump 6 due to stop of the bubble bath operation switch is actuated with the time (t1) delayed after the stop of the switch, wherein the inertia motion time of the circulation pump 3 is included in said time (t1) (buffer time). An opening/closing valve 7 on an ozone pasteurizing path 5 is opened at the same time as starting of the ozone pasteurizing pump 6. This delay for the time (t1) allows an ozone supply path 9 to open only during the period in which a sufficient suction force due to the ozone pasteurizing pump 6 acts on the ozone supply path 9 side, which should eliminates risk of counterflow of the bathing water (circulative water) to the ozone supply path 9.

Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a bubble bath device having a function of sterilizing bath water using ozone.

<Prior art and its problems> As a bath device that can perform ozone sterilization, the Utility Model was developed in 1983-1997.
The device described in Publication No. 639 is publicly known, but this bath device can perform ozone sterilization only when jet operation is performed using a large-capacity pump, and therefore, it can be operated for a long time even when there are no bathers. It was unsuitable for ozone sterilization operation that requires Furthermore, since ozone is mixed into the bathtub at the jet nozzle, there is also the problem that ozone is introduced into the bathtub without undergoing a sufficient reaction.

For this reason, in adding an ozone sterilization function to a bubble bath device, the inventor of the present invention proposed that, in addition to a circulation path for bubble bath operation in which a bubble bath circulation pump is provided, a circulation path that once branches from the middle of the circulation path and then returns to the circulation path. In addition to providing an ozone sterilization route,
An ozone sterilization pump was provided in the ozone sterilization path, and an ozone supply path from an ozone generator was connected to the ozone sterilization path. When performing ozone sterilization operation after bubble bath operation, only the ozone sterilization pump is driven.
It was decided to operate by supplying ozone to the ozone sterilization route. By doing this, it is possible to sufficiently purify the bathtub water at low operating costs for a long time even when no one is bathing, and it is also possible to sufficiently react the ozone before it enters the bathtub. made possible.

However, when two pumps, the circulation pump and the ozone sterilization pump, are installed and operated in a switching manner, there is a problem that the circulating water flows back toward the ozone generator due to the influence of inertia of the pump that remains even after the switch is turned off. Ta.

Therefore, the present invention is a bath device that is equipped with an ozone sterilization circuit in addition to a circulation path for bubble bath operation, and switches and drives two pumps to perform bubble bath operation and ozone sterilization operation, and the circulating water is directed to the ozone generator side. To provide a bubble bath device with an ozone sterilization function that does not cause water to flow in.

<Means for Solving the Problems> In order to achieve the above object, the bubble bath device with ozone sterilization function of the present invention includes a circulation path for operating a bubble bath, a circulation pump for bubble bath provided in the circulation path, An ozone sterilization path that branches off from the middle of the circulation path and returns to the circulation path, an ozone sterilization pump provided in the ozone sterilization path, and an ozone generator connected to the ozone sterilization path midway. a bubble bath device with an ozone sterilization function, the bubble bath device having an ozone sterilization function and an ozone sterilization function, the bubble bath operation being driven by the circulation pump and the sterilization operation being driven by the ozone sterilization pump do not overlap with each other; The first feature is that a buffer time is provided.

Further, the bubble bath device with ozone sterilization function of the present invention has the above-mentioned first feature.
In addition to the above feature, the second feature is that the ozone supply path is opened after the ozone sterilization pump starts driving, and the ozone supply path is closed before the ozone sterilization pump stops driving. Toshide is here.

Further, the bubble bath device with ozone sterilization function of the present invention has the above-mentioned first feature.
In addition to the above feature or the second feature, a third feature is that the ozone generator and the check valve of the ozone supply path are provided at a position higher than the overflow edge of the bathtub.

Further, the bubble bath device with ozone sterilization function of the present invention has the above-mentioned first feature.
In addition to the feature or the second feature, the ozone sterilization pump is a self-priming pump, and an ozone generator and a check valve of the ozone supply path are provided at a position higher than the self-priming discharge residual amount of the pump. is the fourth feature.

<Operation> According to the first feature of the present invention, since a buffer time is provided between the bubble bath operation and the ozone sterilization operation,
Mutual interference between the two operations is prevented when transitioning from bubble bath operation to ozone sterilization operation and when transitioning from ozone sterilization operation to bubble bath operation. Therefore, it is also possible to prevent circulating water from flowing back toward the ozone generator due to the strong action of the circulation pump for bubble bath operation.

According to the second feature of the present invention, in addition to the first feature, during ozone sterilization operation, the ozone supply path is opened and closed only when the ozone sterilization pump is operating substantially sufficiently. Therefore, it is more reliably prevented that the ozone sterilization pump becomes insufficient in suction and the circulating water flows back from the ozone sterilization passage toward the ozone generator.

According to the third feature of the present invention, in addition to the first or second feature, the check valve of the ozone supply path and the ozone generator are provided at a position higher than the overflow edge of the bathtub. At times, bath water is prevented from entering the ozone generator, and even if bath water enters the ozone supply path at abnormal times, the check valve prevents the bath water from entering the ozone generator.

According to the fourth feature of the present invention, in addition to the first or second feature, the ozone generator and the Since the stop valve is provided, bath water is prevented from entering the ozone generator under normal conditions, and the check valve also prevents bath water from entering the ozone generator during abnormal conditions.

<Example> FIG. 1 is an overall configuration diagram showing a first example of the device of the present invention;
FIG. 2 is a time chart showing 54477 examples of operations of each member.

A bathtub 1 is provided with a circulation path 2 for operating a bubble bath and a circulation pump 3 for bubble bath. The bubble bath operation is performed by driving the pump 3 to circulate bath water through the circulation path 2. A back leg switching valve 2 is installed at the spout La and 1a to the bathtub L.
Switching is performed at a. During the bubble bath operation, a part of the bath water flowing through the circulation path 2 is circulated to the filter 4 and filtered. 4a, 4a are three-way valves, and by switching these, the filter 4 can be backwashed.

An ozone sterilization path 5 is branched from the middle of the circulation path 2,
It passes through the ozone sterilization pump 6 and is piped to return to the circulation path 2 again. 7 is an on-off valve for the ozone sterilization channel 5. An ozone supply path 9 from an ozone generator 8 is connected to the ozone sterilization path 5 on the suction side of the ozone sterilization pump 6 via a check valve 1° and an on-off valve 11.

The check valve 10 and the ozone generator 8 are provided at a higher position than the overflow edge of the bathtub l.

During ozone sterilization operation, the ozone sterilization pump 6 is turned on.
When the on-off valve 7 opens, the ozone generator 8 is turned on, and the on-off valve 11 is opened, bath water enters the ozone sterilization path 5 from the bathtub 1 through the circulation path 2, and the ozone generator 8
The ozone sent from the factory is mixed in and sterilized.
Return to the bathtub.

Although the ozone sterilization operation may be started independently, it is usually configured to continue for a certain period of time following the end of the bubble bath operation. In this case, so that the bubble bath operation and the ozone sterilization operation do not actually overlap with each other,
Provide a buffer time between both operations. That is, as shown in FIG. 2, when the bubble bath operation switch is turned off, the circulation pump 3
The supply of power to the circulation pump 3 is stopped, and the circulation pump 3 is stopped. However, it takes some time to completely stop, and during that time the pump 3 continues its inertial operation. Therefore, when the bubble bath operation is suddenly stopped, the ozone sterilization pump 6 is started to be driven after the switch is stopped by a time tl (l negotiation time) that includes the inertia operation time of the circulation pump 3. There is. The on-off valve 7 of the ozone sterilization channel 5 is opened at the same time as the ozone sterilization pump 6 starts to be driven. By providing the buffer time t1 in this way, it is possible to prevent the residual pressure from the circulation pump 3 from being applied to the ozone sterilization channel 5 and further to the ozone supply channel 9 side.

On the other hand, a buffer time is also provided for the ozone sterilization operation that is started after the buffer time of time t. That is, even when the ozone sterilization pump 6 starts operating, the on-off valve 11 of the ozone supply path 9 does not open at the same time, but is delayed by the time t2, which includes the time required for the ozone sterilization pump 6 to start up. Open/close valve 1
1 is open. The ozone generator 8 has an on-off valve 11
Driving is started in synchronization with. By delaying the operation by 11 hours in this way, the ozone supply path 9 is opened only while sufficient suction force by the ozone sterilization pump 6 is working on the ozone supply path 9 side, and therefore, the ozone supply path 9 is opened. The risk of backflow of bath water (circulated water) is also eliminated. If the on-off valve 11 of the ozone supply path 9 is opened at the same time as the ozone sterilization pump 6 is driven, there is a risk that bath water will enter the ozone supply path 9 side from the ozone sterilization path 5 in the initial stage.

Similarly, when the ozone sterilization operation is stopped after the ozone sterilization operation for a predetermined period of time, the on-off valve 11 is first closed before the drive of the ozone sterilization pump 6 is stopped, and the pump 6 is turned on after a certain period of time t3. The drive is stopped and the on-off valve 7 is closed.

Further, when the bubble bath operation switch is turned on by a bather or the like during ozone sterilization operation, the on-off valve 11 is first closed, the ozone generator 8 is stopped, and t.

After 14 hours, the ozone sterilization pump 6 and the on-off valve 7 are stopped, and after a 14-hour buffer period, the circulation pump 3 is stopped.
starts driving. The 11 hours is a time including the inertia operation time of the ozone sterilization pump 6.

In addition, even if the on-off valves 11 and 7 malfunction and the pressure of the circulation pump 3 is applied to the ozone sterilization supply path 9,
The check valve 10 can prevent ozone from entering the ozone generator 8. Furthermore, since the ozone generator 8 and the check valve 10 are provided at a position higher than the overflow edge level L+ of the bathtub l, bath water is prevented from entering the ozone generator 8 in normal times, and The check valve 10 remains open during normal times and exerts a check effect only when the on-off valves 7 and 11 are abnormal, so that clogging of the valve due to bath water hardly occurs.

FIG. 2 is an overall configuration diagram showing a second embodiment of the device of the present invention. In this embodiment, the ozone sterilization pump 6 is a self-priming pump, and the ozone generator 8 and check valve 10 are provided at a position higher than the self-priming discharge level L2 of the pump 6. Further, the on-off valve 11 is provided on the suction side of the pump 6 of the ozone sterilization channel 5 instead of being provided in the ozone supply channel 9. Even if the on-off valve 11 is provided in this position, the on-off valve 1 of the first embodiment described above can prevent bath water from entering into the ozone supply path 9 side.
It plays the same role as 1. The other configurations are the same as in the first embodiment. Components that perform the same function are given the same reference numerals. Also in this embodiment, the pump 3.6, the on-off valve 7.
No. 11 and the like perform the same driving operations as those already described in the first embodiment. The difference between this embodiment and the first embodiment is that since the ozone sterilization pump 6 is of a self-priming type, the ozone generator 8 and the check valve lO are provided at a position higher than the self-priming discharge residual level L2. Therefore, the same effect as in the first embodiment can be obtained at a lower position (overflow edge level L of the bathtub 1, lower position).

Effects> The present invention has the above configuration, and according to the bubble bath device with an ozone sterilization function according to claim 1, a buffer time is provided between the bubble bath operation and the ozone sterilization operation, so that there is no time difference between the two operations. mutual interference can be prevented. Therefore, the ozone sterilization operation can be performed without any trouble, and it is also possible to prevent circulating water from entering the ozone generator side due to the influence of the bubble bath operation.

Further, according to the bubble bath device with ozone sterilization function according to claim 2, in addition to the effects achieved by the configuration according to claim 1,
Since the ozone supply path is opened and closed when the ozone sterilization pump is substantially operating sufficiently, it is possible to reliably prevent bath water from entering the ozone generator side due to insufficient operation of the ozone sterilization pump. .

Moreover, according to the bubble bath device with an ozone sterilization function according to claim 3, in addition to the effects achieved by the configuration according to claim 1 or 2, it is possible to more reliably prevent bath water from entering the ozone generator.

According to the bubble bath device with an ozone sterilization function according to claim 4, in addition to the effects achieved by the configuration according to claim 1 or 2, the position of the ozone generator and the check valve is lower than the overflow edge level of the bathtub. Even if it is low, it is possible to effectively prevent bath water from entering the ozone generator.
