[0001]
[Industrial application fields]
The present invention relates to a bath apparatus, and in particular, a bather can use the hot water circulating in a bathtub hot water purifier for cleaning, such as filtration, heat retention, and sterilization while forcibly circulating hot water in the bathtub according to his / her preference. The present invention relates to an apparatus capable of coloring a free color.
[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]
The apparatus body 4 is forced to circulate hot water through a filtration tank 5 loaded with various granular filter media such as activated stones and porous ceramic balls and fibrous filters alone or in combination in order to remove dirt in the bath water. A cleaning pump such as a circulation pump 6 for heating, a heater 7 for keeping hot water at an appropriate temperature, and an ozonizer 8 for sterilizing hot water with ozone are provided.
[0005]
Reference numeral 10 denotes a prefilter attached to the tip of the hot water suction pipe 3 in order to remove a large amount of dirt before the apparatus body 4 is pumped up. 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. Therefore, reference numeral 12 denotes a jet nozzle, and reference numeral 12 denotes an intake pipe for sucking air from the negative pressure portion into the jet nozzle 11.
[0006]
An electromagnetic valve 13 for opening and closing a pipe line is provided at the tip of the intake pipe 12, and the ozonizer 8 is provided in the middle. When the electromagnetic valve 13 is opened, air sucked from the intake pipe 12 is discharged from the jet nozzle 11. When the ozonizer 8 is operated, the sucked air is ozoned and the hot water 2 in the bathtub 1 is sterilized by ozone.
[0007]
In the apparatus configured as described above, the bathtub water is cleaned by removing large dirt with the prefilter 10, filtering with the filtration tank 5, heating with the heater 7, and then spraying again from the fountain pipe 9 into the bathtub 1. Let
[0008]
If the solenoid valve 13 of the intake pipe 12 is opened at the time of this cleaning, the jet nozzle 11 at the tip of the fountain pipe 9 is sucked through the intake pipe 12 from the negative pressure portion formed by increasing the flow rate of hot water. When air is spouted into the bathtub 1 together with hot water to form a bubble bath, and the ozonizer 8 is operated to ozonize the air sucked from the intake pipe 12, the hot water 2 in the bathtub 1 is sterilized with ozone.
[0009]
In addition, recently, bathers not only simply clean hot water with a cleaning device and enjoy a bubble bath, but also try to obtain a warming effect and a beauty effect by adding various commercially available bath agents. It became so.
[0010]
Commercial bathing agents contain not only various heat-retaining and cosmetic ingredients, but also fragrances and coloring agents, so when bathing agents are added, hot water gives off a specific fragrance and at the same time has a specific color. Colored, bathers enjoy the scent and color at the same time.
[0011]
[Problems to be solved by the invention]
However, scents and colors vary considerably from person to person, and if a particular scent or color is applied to hot water by bathing agents, bathers whose scents and colors do not meet their preferences It must be unpleasant until the scent or color disappears, but there is a problem because the color cannot be easily erased.
[0012]
In other words, when the hot water is scented and colored by the bathing agent, the scent will disappear from the surface of the bathtub for a relatively short time or be absorbed by the filter medium of the bath water purifier. Also, you can add your favorite fragrance to the hot water and shield it, so it doesn't matter much.
[0013]
However, the color will not disappear unless the hot water is changed. If you use a bath water purifier, the hot water will be changed over a long period of time, so it will be adsorbed by the filter medium or slightly changed after each bath. There is, but it does not disappear easily though it gets thinner as the day passes.
[0014]
In addition, if the same bath agent is added even if the hot water is changed, the same color will be given, and the bather will have his / her own preference unless there is a commercially available bath agent containing various colorants in the same heat-retaining agent or beauty agent. Even if a bathing agent with various colorants blended with the same heat-retaining agent or beauty agent cannot be applied to hot water, the bather has to be able to color her favorite color. You will have to change the hot water every time you change.
[0015]
In this way, if the bather changes the hot water every time the bather changes in order to put his favorite color on the hot water, it is natural that there is no point in using the bath water cleaning device, and at the same time fuel and water are used. This is practically impossible because of the waste of a lot.
[0016]
The present invention eliminates the drawbacks of the prior art as described above, and can enjoy bathing with clean and appropriate hot water at any time for 24 hours without changing hot water over a long period of time, and adding a commercially available bathing agent to hot water. It is an object of the present invention to provide a bath water purifier that can color hot water in a desired color while obtaining a heat retaining effect and a beauty effect.
[0017]
[Means for Solving the Problems]
