Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to an apparatus for cleaning bath water in a home bath, and particularly to a so-called bath water cleaning and heating method that can constantly take bath water for 24 hours. It is related to a 24-hour bath device.

(Prior art) Bath water is circulated through a filtration device, an activated stone tank, and the like using a circulation pump to remove and activate hot water dirt. .

On the other hand, recently, we have developed a so-called 24-hour bath device that not only removes and activates hot water dirt, but also uses a heater to heat it and keep it constantly at an appropriate temperature for 24 hours to take a bath 24 hours any time. Was done.

In this case, it is necessary to sterilize to keep the cleanliness of the hot water and to prevent the generation of bad smell and E. coli.
Ozone sterilization has come to be widely used due to the development of a small high pressure discharge type ozone generator as this sterilization treatment.

Recently, a bubble bath device has been developed that jets out bathtub hot water into the bathtub while sucking in air, thereby giving a massage effect to the bather by the infinite number of bubbles generated in the bathtub. Was added to

(1) Bath water inlet (2) Filtration device (3) Circulation pump (4) Electric throw-in heater (5) Activated stone tank (6) Ozone suction device ( (7) Injection pipes with ozone generators are installed. (7) Jet jets are being developed in which bath jets are arranged in series in the circulation line of bath water.

In this apparatus, bath water subjected to filtration, heating, and activation treatments is jetted into the bath while sucking ozone air.

(Problem to be Solved by the Invention) The problem of the conventional bathtub cleaning apparatus as described above is firstly a problem of electric leakage.

Conventionally, as described above, the bathtub hot water is heated directly by an electric throw-in heater, but when the heater is exposed due to contact or cracking of an insulating coating material such as ceramics covering the heater. There is a risk of electric shock to bathers due to electric leakage.

 The next problem is that of unreacted ozone.

That is, as described above, in the conventional ozone sterilization, high-concentration ozone is constantly released together with the jet jet into the bathtub, and the unreacted ozone is sucked by the bather, which may be harmful to health.

Furthermore, in the conventional apparatus, the suction of ozone air for ozone sterilization also serves as the suction of air as a bubble bath function, so that it is constantly a bubble bath. Cannot be in a state.

The present invention solves the problems of the conventional technology as described above,
The invention was created with the aim of providing a bathtub hot water cleaning device that is highly safe in terms of electrical and health for bathers and that the bather can select and operate as desired. It was done.

(Means for Solving the Problems) That is, the present invention provides a filtration device for circulating a bathtub hot water,
An activation treatment device that also serves as a circulation pump, an indirect heating device, an ozone suction device, and an ozone recovery device is sequentially installed in series, and a branch pipe for jet ejection that short-circuits directly to the bathtub immediately after the indirect heating device is provided. It is a bathtub cleaning device.

(Operation) The present invention is configured as described above, and since the heating method is an indirect heating method, the insulation is complete and the bather does not have a risk of electric shock.

Further, the unreacted ozone is collected in the activation treatment device also serving as the ozone recovery device, so that there is no fear that the unreacted ozone is released into the bathtub, and therefore, there is no need to fear the damage to the bather's health.

Further, since the jet ejection pipe is provided separately from the main pipe, the bather can activate the bubble bath function as needed by switching the circulation path of the bath water.

Therefore, the hot water 2 in the bathtub 1 sucked from the hot water suction pipe of the hot water draining unit 3 enters the cleaning processing unit 4 through the hot water suction hose 5, is subjected to the cleaning treatment, and is discharged when discharged as a natural flow. In the case of discharging as a jet jet from the drain pipe of the hot water unit 3 through the hot water hose 6, it is discharged again into the bathtub from the jet outlet at the tip of the jet pipe of the hot water unit 3 through the jet hose 7. .

The internal structure of the cleaning unit 4 is as shown in FIG. 2, and the hot water hose 5, the hot water hose 6, and the jet hose 7 connecting the hot water unit 3 and the cleaning unit 4 as described above. Three hoses are connected to the hose joint 8 including the drain hose attached to the machine frame 9.

The cylindrical filter 20 is inserted into a plurality of through holes 18 at appropriate intervals.
A tap hole 19 connected to a blanch pipe 17 provided with a filter support 16 fitted and positioned in the tap port 14 of the filter case 12 is stored and supported on the upper end surface of the filter 20. The filter case 21 is fixed by closing the filter case lid 23 while pressing the filter holder 21 via the spring 22.

Therefore, the hose joint 8 with the check valve 25 interposed
The hot water that has entered the filtering device 11 through the connection hose 24 to the hot water inlet 13 is filtered from the outer circumference of the filter 20 toward the inner circumference, enters the hot water pipe 17 through the hot water hole 18, and exits.
After passing through 19 and 14, it is sent to the circulation pump 28 by the connecting hose 26.

The drain port 15 and the drain hose of the hose joint are connected by a connecting hose 27.

Reference numeral 28 denotes a circulation pump for forcibly circulating hot water in the circulation pipeline, and the hot water inlet 29 is connected to the connecting hose 26 as described above.
The outlet port 30 of the filtration device 11 is connected to the outlet port 30 of the indirect heating device 32 by a connection hose 31.

The details of the indirect heating device 32 are as shown in FIG. 3, and a heating element 36 having an electric heater 37 provided in an insulating oil 38 such as silicone oil, and a hot water flow path surrounding the heating element 36 A water tank 33 having an inlet 34 and an outlet 35 forming
It comprises an overflow tank 39 connected to a heating element 36 for absorbing the volume expansion of the insulating hot water 38 during heating.

Therefore, the hot water that has entered from the hot water inlet 34 flows while being indirectly heated in contact with the heating body 36 in the flow path formed as a gap between the heating body 36 and the water tank 33, and after being heated to a predetermined temperature, the hot water outlet. It exits from 35 and is sent to the bath 37 of the three-way valve 36.

The three-way valve 36 uses a pulse motor 38 as a drive source, and a control mechanism 39
The three-way valve 36 is opened and closed, and the switching of the three-way valve 36 switches the pipe line so that hot water flows from the jet port 40 to the jet drain pipe 60 connected to the joint hose 7 via the hose joint 8. Can be

Therefore, by the switching of the three-way valve 36, bubbles are generated in the bath tub, and the bath becomes a bubble bath.

The three-way valve 36 has a function of switching the ozone supply pipe for ozone sterilization other than the above-described switching of the pipe through which the hot water flows, which will be described later.

The natural outlet 41 of the three-way valve 36 is connected to a venturi-type ozone inhaler 42, and sterilizes hot water flowing through the pipeline by ozone from the ozone generator 59 or the ozone recovery device sucked from the vent.

43 is an activation treatment device also serving as an ozone recovery device,
Activated stone 48 was filled between upper and lower activated stone steels 51 and 52 provided with countless through holes in a cylindrical activated stone tank 44 provided with a hot water inlet 45, a hot water outlet 46 and a drain opening 47 on the bottom surface. After the activated stone basket 49 is positioned with the tap hole 50 on the bottom surface in the tap hole 46 of the activated stone tank 44, the activated stone 52 at the top is spring-loaded 53.
The activated stone tank lid 54 is fixed and accommodated by closing the activated stone tank lid 54 while pressing downward.

The ozone inhaler 42 and the hot water inlet 45 of the activation processing device 43 are connected by a connecting pipe 56, and are sterilized by absorbing ozone from the ozone inhaler 42 and enter the activation processing device 43 from the hot water inlet 45. The activated stone tank 44 and the activated stone basket
Going up the gap with 49, eventually activated stone basket 49
Of the activated stone 52, flows into the activated stone basket 49 through the activated stone 52, flows down while being activated by the activated stone 48, and exits from the activated stone 51 below and taps 50 and 46. Spilled through.

When the hot water flows down the activated stone basket 49 while being activated by the activated stone 48, the activation processing device 43 receives the resistance of the activated stone 48, the flow speed is reduced, and a gas-liquid separation effect occurs, and the unreacted material in the hot water is generated. Ozone is separated and gradually accumulates in the ozone storage 55, which is an upper cavity, so that it also has the function of an ozone recovery device.

As the recovery of unreacted ozone by the activation treatment device 43 proceeds as described above, the ozone recovery amount of the ozone storage unit 55 increases, and when the predetermined recovery amount is reached, the recovered ozone is discharged out of the device. It is necessary to dispose of detoxified air by performing waste ozone treatment.

In this embodiment, which will be described in detail later, as ozone treatment, the collected ozone is sent to the ozone absorber 42 and reused for sterilization, whereby the air in the ozone reservoir 55 has an ozone concentration equal to or lower than a predetermined level. In this method, water is released into hot water that has been cleaned.

On the other hand, as described above, the hot water that has been subjected to the recovery and activation processing of the unreacted ozone in the ozone recovery device 43 also serving as the ozone recovery device is connected to the hot water discharge hose 6 from the outlet 46 through the hose joint 8. It flows out into the drainage pipe 57.

58 is an activation treatment device 43 that has been subjected to the above-described waste ozone treatment.
This is a venturi-type air suction device provided in the middle of a natural drainage pipe 57 for discharging the air in the ozone storage section 55 into the hot water after the cleaning process.

Next, an ozone sterilization process will be described with reference to FIG. 4 while reusing the ozone collected by using the activation processing device 43 as described above.

The air from the air pump 61 is sent to the ozone generator 59 via the tube 62, where a part of the air is ozonized, and the ozone air is sent to the three-way valve 36 via the tube 63.

The three-way valve 36 interlocked with the control mechanism 39 is provided with a hot water flow switching chamber 69 for switching the flow of the heated hot water between the ozone suction device 42 and the jet drain 60 as described above, and a flow of ozone air. Ozone air flow switching chamber 64 for switching directions
It consists of.

In a state where the sterilization process is performed with the ozone air generated by the ozone generator 59, the ozone air flow switching chamber 64
The valve is switched so that the conduit between the inlet 65 and the outlet 66 is opened.

Therefore, the ozone air sent from the ozone generator 59 via the tube 63 is supplied to the ozone air flow switching chamber 64.
The water enters the inlet 65 from the inlet 65, exits from the outlet 66, passes through the tube 70, and is sucked into the hot water flowing through the pipeline via the ozone inhaler 42.

As the unreacted ozone in the hot water is recovered in the activation processing device 43 and the ozone is stored in the ozone storage unit 55, the pressure in the activation processing device 43 increases and the water level gradually decreases.

The activation treatment device 43 is provided with a lower float switch 71 that operates by detecting the lower limit water level and an upper float switch 72 that operates by detecting the upper limit water level, and the amount of collected ozone is reduced as described above. When the water level further decreases, the lower float switch 71 operates.

This state indicates that a predetermined amount of ozone has been collected in the ozone storage unit 55, and is a state in which the supply of ozone air to the ozone suction device 42 is switched from the ozone generator 59 to the collected ozone in the ozone storage unit 55. is there.

Therefore, the operation of the air pump 61 is stopped by the signal that the lower float switch 71 has been operated, the generation of ozone air by the ozone generator 59 is stopped, and the valve of the ozone air flow switching chamber 64 is connected to the outlet 66. The pipe is switched so that the pipe at the inlet 65 is closed and the pipe at the inlet 67 is opened.

For this reason, the ozone air in the ozone storage section 55 of the activation processing device 43 enters the ozone air flow switching chamber 64 from the inlet 67 via the tube 73, exits from the outlet 66, and is sucked from the ozone suction device 42 via the tube 70. To be used for sterilization.

If the sterilization with the collected ozone by the above circulation is continued for a predetermined time, the concentration of the ozone air in the ozone storage unit 55 decreases, and the concentration of the ozone air does not cause a problem even if the ozone air is discharged outside the apparatus.
This circulation is stopped when a time determined in advance by an experiment has elapsed, and the collected ozone air is discharged outside the apparatus.

Therefore, when the circulation of the recovered ozone air is performed for a predetermined time, the valve of the ozone air flow switching chamber 64 is switched so as to close the pipe of the outlet 66 with respect to the inlet 67 and open the pipe of the outlet 68.

The ozone air having a low concentration in the ozone storage unit 55 of the activation processing device 43 due to the switching of the pipeline enters the ozone air flow switching chamber 64 through the inlet 67, exits through the tube 68, and exits through the tube.
The air is sucked from the intake device 58 into the natural drainage pipe 57 via 74.

When the ozone air in the ozone storage section 55 of the activation processing device 43 is exhausted as described above, the pressure in the device decreases, so that the water position rises and eventually reaches the upper limit water level, and the upper float switch 72 operates, A signal indicating that the exhaust has been completed is issued.

With this signal, the air pump 61 and the ozone generator 59
Starts operating, and at the same time, the ozone air flow switching chamber 64
Is closed with the conduit of the inlet 67 and the outlet 68, and the inlet 65 and the outlet
The valve is switched so that the line to 66 is opened, and sterilization by the ozone air generated by the ozone generator 59 is started again.

As described above, the ozone sterilization alternates between the ozone air generated by the ozone generator 59 and the ozone air generated by the unreacted ozone collected by the activation processing device 43 by switching the ozone air line by the three-way valve 36. It is performed while switching.

(Effect) The configuration and operation of the present invention are as described above.
The bath is heated by indirect heating using insulating oil as a heat medium, so there is no danger of electric shock to the bather.Next, the jet drain pipe is branched immediately after the heating device, preventing a pressure drop and preventing a strong jet. By jetting the jet into the bathtub, you can enjoy an effective bubble bath, and also inhale ozone in front of the activation treatment device, so that unreacted ozone can be collected by gas-liquid separation in the activation treatment device and collected in the bathtub. A bathtub hot water purifying device is provided, in which no unreacted ozone is released into the bath, and there is no risk that bathers inhale ozone and harm their health. .
