BACKGROUND OF THE INVENTION
The present invention relates to a bath apparatus, and in particular, while purifying the hot water in the bathtub, for example, filtering and sterilizing, and keeping the bath temperature at the same time, keeping the bath water constantly clean and suitable temperature, it can be used anytime for 24 hours. The present invention relates to a so-called 24-hour bath apparatus that can take a bath at the time of bathing.
[0002]
[Prior art]
Recently, the hot water in the bathtub has been actively used to keep the hot water in the bathtub clean and suitable temperature, so that it can be comfortably bathed anytime for 24 hours and save water.
[0003]
One example of such a bath water purifier is as shown in FIG. 5, where 1 is a bathtub, 2 is hot water, 3 is a hot water pipe for pumping up hot water 2 in the bathtub 1, and 4 is a hot water pipe. 3 is an apparatus main body in which devices for purifying the hot water pumped up in 3 are arranged together, and 9 is a fountain pipe for causing the hot water processed in the apparatus main body 4 to be ejected into the bathtub 1 again.
[0004]
In order to remove dirt in the bath water, the apparatus main body 4 is forced to have a filtration tank 5 loaded with various granular filter media such as activated carbon, activated stone, porous ceramic balls, or a fibrous filter alone or in combination, and hot water. A circulation pump 6 for circulation, a heater 7 for keeping hot water at an appropriate temperature, and a cleaning treatment device such as an ultraviolet lamp 8 for sterilizing the hot water with ultraviolet rays are connected in series, and a suction pipe is provided in the filtration tank 5. 3, a fountain pipe 9 is connected to the heater 7 to form a cleaning pipe line.
[0005]
Reference numeral 10 denotes a prefilter attached to the tip of the hot water suction pipe 3 in order to remove large dirt before pumping it up into the apparatus main body 4. Reference numeral 11 denotes hot water after the cleaning process is jetted into the bathtub 1 as a jet flow having a high flow velocity. The intake pipe 12 is a jet nozzle connected to the ejector section.
[0006]
An intake valve 13 such as an electromagnetic valve for opening and closing a pipe line is provided at the tip of the intake pipe 12 connected to the ejector portion of the jet nozzle 11. When the intake valve 13 is opened, air is sucked from the intake pipe 12 by the intake force of the jet nozzle 11. This air is mixed into the hot water at the ejector section, and the air is spouted from the jet nozzle 11 together with the hot water into the bathtub 1 to form a bubble bath.
[0007]
Further, in this apparatus, in order to remove dirt from the filter medium of the filtration tank 5, so-called backwashing in which the hot water is caused to flow back into the tank and discharged from the hot water discharge pipe 17 or the jet flow is strengthened, the hot water is less resistant. Switching valves 14 and 15 are respectively provided in the hot-water pipe 3 and the fountain pipe 10 so that the pipes can be switched so that the bypass pipe 16 flows.
[0008]
18 is a check valve provided in the hot-water pipe 3 to prevent the hot water in the pipe from draining when the water is filled or the hot water from flowing back into the bathtub 1 when the operation of the circulation pump 6 is stopped. 19 is a differential pressure sensor for detecting a shortage of water in the pipe line based on the pressure difference between the suction side and the discharge side of the circulation pump 6 to prevent idling of the circulation pump 6 and emptying of the heater 7. Is a hot water temperature sensor that constantly detects the temperature of the hot water and sends it to the control device in order to control the power supply to the heater 7 and keep the temperature of the hot water at an appropriate temperature.
[0009]
In the apparatus configured as described above, the user sets various operating conditions as necessary using an operation panel that functions as a key input device and a display device as shown in FIG. The conditions can be displayed, the operation is set by the operation / stop key 21, and the hot water 2 in the bathtub 1 is sterilized by the ultraviolet lamp 8 after removing large dirt by the prefilter 10, and is filtered by the filtration tank 5. After being filtered and heated by the heater 7, it is ejected from the jet nozzle 11 at the tip of the fountain pipe 9.
[0010]
In addition, a jet mode can be set by a jet key 22 so that a jet stream in which air is mixed in hot water is jetted into a bathtub so that a bather can enjoy a so-called bubble bath.
[0011]
23 is a bathing key. When a bather first operates the bathing key 23, a predetermined time thereafter is set as a bathing time zone. For example, when ozone sterilization is performed, ozone sterilization is performed only in this bathing time zone. Control is performed to stop and protect the bather from harmful ozone, or various controls can be performed based on the bathing time zone as in the setting of the sterilization time zone in the present invention.
[0012]
When the jet key 22 is set to be strong, the switching valves 14 and 15 are switched, and the hot water 2 in the bathtub 1 pumped up from the hot water suction pipe 3 flows directly into the hot water pipe 9 via the bypass pipe 16 and flows through the hot water circulation path. The resistance is reduced, and a strong jet flow is ejected from the jet nozzle 11.
[0013]
If it is desired to continue the cleaning process and wash the filter medium in the filtration tank 5, although not shown, the switching valves 14 and 15 are switched by the setting of backwashing with the backwashing key, and the hot water in the bathtub 1 pumped from the hot water suction pipe 3 is switched. There is also provided a backwash mode in which 2 is caused to flow back in the filtration tank 5 via the bypass pipe 16 and discharged from the hot water pipe 17 so-called backwashing.
[0014]
Further, a display switching key 24 and a setting change key 25 are provided in the operation panel shown in FIG. 6, and the display on the display panel 26 changes to the hot water temperature or time by the operation of the display switching key 24. The hot water temperature or time setting is changed by the operation 25, and the setting state of the operating condition by the above key operation is displayed by a plurality of display lamps 27.
[0015]
Therefore, when the display switch key 24 is operated to switch the display panel 26 to the time display, and the setting change key 25 is further operated to set the time, the bathing time zone for one day can be set without operating the bathing key 23 as described above. Can be set automatically.
[0016]
When the bathing time zone is automatically set using the display switching key 24 and the display panel 26, the hot water temperature is limited to the bathing time zone in addition to the control when the bathing key 23 is operated manually as described above. Therefore, it is convenient that the bathing temperature is maintained and the non-bathing time period is kept low and the heating cost is saved.
[0017]
In addition, as shown in this example, if the bath water sterilization is changed from the conventional ozone sterilization with the ozoneizer to the ultraviolet light sterilization with the ultraviolet lamp 8, no harmful ozone is generated from the hot water even when sterilizing at the time of bathing. You can enjoy bathing in clean water.
[0018]
[Problems to be solved by the invention]
However, when the bath water is sterilized by the ultraviolet lamp 8, the ultraviolet lamp 8 is expensive, and the illuminance decreases as the irradiation time elapses. Therefore, if the apparatus is used for about one year and the irradiation time is about 10,000 hours, the lifetime has come to be replaced.
[0019]
Therefore, in the case of ultraviolet sterilization, in order to extend the life of the ultraviolet lamp 9 as much as possible, it is considered that the application of power to the ultraviolet lamp 8 is ON / OFF controlled so as not to be sterilized throughout the day.
[0020]
In this control method, a sterilization time zone is defined only during a predetermined time when bathing within a day is predicted, and a sterilization is performed by applying power to the ultraviolet lamp 8 only during this sterilization time zone, There is a method of repeatedly applying and stopping power supply to the ultraviolet lamp 8 in a short time.
[0021]
If a certain period of time is set as a sterilization time period and controlled, the UV lamp 8 is applied with a power source for only several hours a day, so the life is considerably extended. The hot water must be replaced frequently even when the gasification device is installed.
[0022]
In other words, because the lifestyle is not the same every day, the bathing time zone and the sterilization time zone may not always match. In addition, even if the bathing time zone and the sterilization time zone coincide with each other, even if the sterilized hot water is not sterilized at all for a long time, the bacteria will multiply again, so in any case the next sterilization time The hot water will be very dirty between the belt.
[0023]
Moreover, if the application and stop of the power supply to the ultraviolet lamp are controlled to be repeated in a short time, the time for applying the power supply to the ultraviolet lamp per day can be reduced to about half with almost no sterilization effect, but the ultraviolet lamp 8 is turned on. On the contrary, the service life is shortened due to the effect that -OFF is frequently repeated.
[0024]
An object of the present invention is to provide a bath water cleaning device that eliminates the drawbacks of the prior art as described above, greatly extends the life of the ultraviolet lamp 8, and further maintains hot water.
[0025]
[Means for Solving the Problems]
Therefore, the present invention pumps hot water in the bathtub with a circulation pump, and circulates a cleaning pipeline provided with various cleaning and heat insulation means such as a filtration device, a sterilization device, a heating device, etc. In the bathtub hot water cleaning apparatus which returns to the bathtub after the treatment, the sterilizing apparatus is provided with an ultraviolet sterilizing apparatus and an ionic sterilizing apparatus, and the input device has an arbitrary time zone within a day. Bathing time setting means to be set as a belt is provided, and in the bathing time zone set by the input device, ultraviolet sterilization by the ultraviolet sterilizer is performed, and in the non-bathing time zone, ionic wind sterilization by the ionic wind sterilizer is performed. It is configured to control so that bathing hours when the hot water stains become severe without adopting sterilization that generates ozone or other harmful gases that may cause health hazards to bathers. Implemented, band non bathing time is an ion wind sterilization can be carried through the day sterilization, moreover, it has solved the problems as possible to shorten the operating time of the UV sterilizer.
[0026]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of the configuration of the present invention will be described with reference to the drawings.
[0027]
FIG. 1 shows a piping diagram of an embodiment of the present invention. In the piping diagram of this embodiment, the same constituent elements as those of the conventional example are given the same reference numerals, so that the same components constituted by them are shown. The description of the part is omitted.
[0028]
In this embodiment, an ion wind generator 28 is provided with an ejector section for forming a bubble bath by increasing the flow velocity at the jet nozzle 11 to form a negative pressure and sucking air based on the pressure difference. Since the intake pipe 12 is connected to the ion pipe, the ion wind generator 28 is provided in the middle of the intake pipe 12 for forming the bubble bath.
[0029]
Accordingly, when the jet key 22 on the operation panel is operated to set the jet mode, the intake valve 13 provided in the intake pipe 12 is opened, and hot water mixed with air from the jet nozzle 11 is jetted into the bathtub 1 as a jet flow. When the ion wind generator 28 is operated simultaneously with opening the intake valve 13, hot water mixed with ion wind is ejected from the jet nozzle 11 into the bathtub 1 as a jet flow.
[0030]
When ionic wind is mixed in the hot water instead of air when enjoying a bubble bath, it not only produces a cleansing action that suppresses the growth of fungi in the bath water, but also generally a sedative action that eliminates irritation. Since the ionic wind is said to be diffused from the bathtub, the bubble bath is more comfortable.
[0031]
The basic configuration of the ion wind generator 28 is as shown in FIG. 2. A needle-like negative electrode and a plate-like positive electrode to which a high voltage of DC number KV, which is rectified by a rectifier circuit after being transformed by a step-up transformer, is applied. The air introduced into the device is opposed to the electrode, and the air introduced into the device is passed between the electrodes to which the high voltage is applied, so that the anion of oxygen generated in the anion generating part around the needle-shaped anion electrode is included. It is a device that discharges as ionic wind.
[0032]
As described above, when air is made into an ionic wind by high-pressure discharge of a needle-like negative electrode, not only oxygen anions but also cations and ozone are generated during high-pressure discharge. And ozone is included in a small amount.
[0033]
For this reason, in the ion wind generator 28 shown in the present embodiment, a retinal negative electrode and an ozonolysis filter filled with an ozone decomposing agent such as activated carbon and a metal catalyst are provided after the high-pressure discharge electrode, and the cation and ozone in the ion wind are provided. The ion wind containing only the oxygen anion is generated.
[0034]
Next, the control device applies UV power to the UV lamp only during the sterilization time zone determined based on the bathing time zone set manually or automatically, and UV power is applied to the UV lamp 8. Based on FIG. 3 and FIG. 4, the stopped non-sterilization zone is operated based on FIG. 3 and FIG. 4 to control the ion wind generator 28 to operate so that the hot water is kept clean by mixing the ion wind into the hot water and preventing the growth of bacteria. I will explain.
[0035]
FIG. 3 is a control block diagram showing a configuration in which the device is controlled entirely by the control device. Reference numeral 29 denotes a key input device provided on the operation panel for setting various operating conditions. In addition to the operation / stop key 21 for setting the operation and the jet key 22 for setting or canceling the bubble bath, the bathing key 23 for manually or automatically setting the bathing time zone, the display switching key 24, and the setting change Key 25 is deployed.
[0036]
That is, the bathing key 23 is a key for manually setting the bathing time zone of the day. When the bathing key 23 is operated for the first time, a bathing time zone of a predetermined time such as 5 hours is set thereafter.
[0037]
The display switching key 24 and the setting change key 25 are keys used for automatically setting the bathing time zone. The user displays the time on the display panel 26 while changing the bathing time zone, for example, from 18:00 to 23:00. Once set according to the life time zone, the same time zone is automatically set as the bathing time zone every day unless the setting is changed.
[0038]
In this way, when the bathing time zone is set by operating the bathing key 23 or operating the display switching key 24 and the setting change key 25, the hot water contaminated in this bathing time zone is immediately cleaned by sterilization. Based on the set bathing time zone, a sterilization time zone in which power is applied to the ultraviolet lamp 8 to perform UV sterilization is automatically set as a time obtained by adding a predetermined time after the bathing time zone has elapsed.
[0039]
That is, for example, when the bathing key 23 is operated or the display switching key 24 and the setting change key 25 are operated to set the bathing time zone from 18:00 to 23:00, in the present invention, after the bathing time zone has elapsed, A time zone from 18:00 to 14:00 including 1 hour is automatically set as a sterilization time zone.
[0040]
Further, as described above, the apparatus is controlled by detecting the hot water temperature by the hot water temperature sensor 20 or by detecting the lack of water by the differential pressure sensor 19.
[0041]
30 is a timer used to control the apparatus in terms of time. As described above, the operation of the bathing key 23 or the setting and setting of the bathing time zone using the display switching key 24 and the setting change key 25 are performed. The sterilization time zone is set based on the bathing time zone and the passage of time is measured.
[0042]
Reference numeral 31 denotes a control device for overall control of the device. The control device 31 includes a CPU 32 that performs various arithmetic processes, a program ROM 33 that stores a control program, a RAM 34 that temporarily stores control data, and the like. It is a micro computer.
[0043]
Reference numeral 35 denotes a circulation pump drive circuit for driving the circulation pump 6, 36 denotes a heater drive circuit for driving the heater 7, and 37 denotes an ultraviolet lamp drive circuit that supplies power to the ultraviolet lamp 8 and lights it.
[0044]
38 is an ion wind generator drive circuit for driving the ion wind generator 28, 39 is an intake valve drive circuit for opening and closing the intake valve 13, and 40 is provided together with the key input device 29 on the operation panel. This is a display device driving circuit for driving a display device 41 including a display panel 26 and a plurality of display lamps 27.
[0045]
The control device 31 operates the ultraviolet sterilization and ozone wind generator in accordance with the program shown in the flow chart of FIG. 4 stored in the program ROM 33, and sterilizes the ultraviolet ray only in the set sterilization time zone. The sterilization time zone is controlled so that the ozone wind generator is activated and ionic wind is mixed to prevent bacterial growth.
[0046]
In the first step S1, it is determined whether or not the operation is set by operating the operation / stop key 21, and when the operation is set, the intake valve 13 provided in the intake pipe 12 is opened in the second step S2. At the same time, the third step S3 ion wind generator 28 is operated.
[0047]
As a result, the air sucked from the intake pipe 12 is changed into ion wind by the ion wind generator 28 and mixed into hot water, filtered from the jet nozzle 11 by the filtration tank 5 and heated to an appropriate temperature by the heater 7, and the ion wind is mixed. Then, the hot water in a state where the bacteria do not propagate is constantly jetted into the bathtub 1, and the hot water of the bathtub is cleaned in the automatically set jet operation state.
[0048]
In the state in which the bath water cleaning process is performed in this manner, it is determined whether or not the sterilization time zone is set in the fourth step S4.
[0049]
As described above, the sterilization time zone is automatically set based on the bathing time zone as an additional time for about 1 hour after the bathing time zone has passed in order to immediately clean the hot water contaminated by bathing. Set to
[0050]
Therefore, whether or not the bathing key 23 has been operated in the same manner as in determining whether or not the bathing time zone has been set in order to determine whether or not the sterilization time zone has been set in the fourth step S4, or It is determined whether or not the timer 30 has detected that a predetermined bathing time has been reached using the display switching key 24 and the setting change key 25.
[0051]
As described above, when it is determined that the sterilization time zone has been set in the fourth step S4, the power is applied to the ultraviolet lamp 8 through the ultraviolet lamp driving circuit 37 in the fifth step S5, and the lamp is turned on. At the same time, the timer 30 starts measuring the sterilization time at the sixth step S6.
[0052]
It is preferable to mix ionic wind in the bath water during bathing because the calming effect of the ionic wind diffused in the bathroom can relax the bather's mood. Since it is not necessary to stop the operation, the apparatus of the present invention is automatically in a jet operation state in which a jet stream mixed with ionic wind for 24 hours is jetted into the bathtub.
[0053]
However, since some bathers may not like the bubble bath, it is determined whether or not the jet has been stopped by operating the jet key 22 in the seventh step S7, and if it is determined that the jet has been stopped, In step S8, the intake valve 13 is closed, and at the same time, the operation of the ion wind generator 28 is operated in the ninth step S9. The jet is manually set by operating the jet key 22 again, or automatically after a predetermined time has passed. Stop until set.
[0054]
In this way, when the jet is stopped, mixing of the ionic wind is stopped, and if the jet is not stopped or is set again even if it is stopped, the ionic wind is mixed and the tenth step S10 Then, UV sterilization is continued until the timer 30 sterilization time period is detected.
[0055]
If it is determined in the tenth step S10 that the timer 30 has detected that the sterilization time period has elapsed, the application of power to the ultraviolet lamp 8 is stopped via the ultraviolet lamp driving circuit 37 in the eleventh step S11 to perform ultraviolet sterilization. If the operation is set after that, the intake valve 13 is opened, and at the same time, the ion wind generator 28 is operated to continue mixing the ion wind into the hot water. Continue the cleaning process to prevent bacteria from growing in the hot water.
[0056]
In the embodiment of the present invention described above, the ion wind generator 28 is provided in the intake pipe 12 connected to the jet nozzle 11 to form the bubble bath, so that the ion wind is stopped when the bubble bath is stopped as described above. The operation of the generator 28 must be stopped, and the ion wind cannot be mixed into the hot water while the operation of the ion wind generator 28 is stopped.
[0057]
However, since the ion wind generator 28 may be provided in an intake pipe connected to an ejector section provided at any position in the pipe line, for example, an intake section connected to the ejector section is provided upstream of the filtration tank 5. If the ion wind generator 28 is installed in the tube, the formation of the bubble bath and the generation of the ion wind are completely independent, and the ion wind generator can be operated for 24 hours. Conveniently, it is better able to prevent the bacteria from growing on the filled filter medium.
[0058]
【The invention's effect】
The present invention is configured as described above, and ultraviolet sterilization is performed only during the sterilization time period determined based on the bathing time period of about one third of the day, so that the life of the ultraviolet lamp is greatly extended. .
[0059]
Moreover, since the sterilization time zone is set based on the bathing time zone, the hot water contaminated by bathing is immediately cleaned by UV sterilization, and in the non-sterilization time zone other than the sterilization time zone, ionic Can prevent the growth of bacteria.
[0060]
In addition, if ionic wind is mixed in the hot water, not only can the growth of the bacteria be prevented, but the ionic wind radiated from the hot water in the bath will give the bather a sedative effect and a relaxed state, allowing them to take a more comfortable bath. It becomes like this.
