Description

  The present invention relates to a bathing apparatus.

  Getting a relaxing time not only physically but also mentally is one of the big goals of bathing. As one of means for obtaining a relaxing effect during bathing, conventionally, lighting for a bathroom, a bathtub, bathtub water, and the like has been used. For example, attempts have been made to provide a visual relaxing effect by reducing the illuminance of the entire bathroom and illuminating a part of the bathroom or the entire surface of the bathtub water with light from indirect lighting. Moreover, the apparatus which floats a lighting fixture in bathtub water, the bathtub which installed the lighting fixture inside the bathtub wall surface, etc. are also known.

On the other hand, a bubble generation bathtub that generates a bubbling water flow in the bathtub water for the purpose of massage effect and body temperature maintenance effect after bathing is known, but the bathtub water is colored by irradiating light to this bubble and visually Bathing devices have been proposed to further promote the relaxing effect. For example, Patent Literatures 1 to 3 disclose a bathtub including a bubble generating unit and a lighting device that irradiates light to the bubbles ejected from the bubble generating unit on a bathtub wall. Patent Document 4 describes a bathtub with a light effect device that produces a light effect by irradiating light of a variable color from an illumination device in the bathtub using a bath water that is clouded by fine bubbles having a diameter of 5 to 10 μm as a screen. Has been.

  In the case of a bathing apparatus such as Patent Documents 1-4, the illumination device for irradiating light on the bubbles is a diffused light irradiation device such as a lamp or LSD, and light is applied to the entire bubbles injected into the bath water. Irradiated. For this reason, it is possible to produce various changes in the color of the entire bubble, but it is not possible to produce light by local or linear light irradiation, and there is a limit to the increase in visual effects. .

  The present invention eliminates the limitations in the prior art as described above, and provides a relaxing effect that enables various light effects that could not be achieved with conventional devices by locally and linearly irradiating bubbles in the bath water. The object is to provide an excellent bathing apparatus.

  The bathing apparatus of the present invention is characterized in that it first comprises bubble generating means for generating fine bubbles having a diameter of 0.2 μm to 100 μm in the bath water, and laser light irradiation means for the bath water.

  The bathing apparatus of the present invention is secondly characterized in that the wavelength of the laser light is 360 nm to 830 nm.

  Furthermore, the bathing apparatus of the present invention is characterized in that an image is projected onto the bathtub water by laser light.

  Furthermore, the bathing apparatus of the present invention is characterized by comprising human body detecting means for preventing irradiation of the human body with laser light.

  In the bathing apparatus according to the first invention of the present application, it is possible to irradiate light locally and linearly to the fine bubbles in the bath water. That is, since laser light is excellent in directivity, monochromaticity, high brightness, operability, and the like, vivid linear color light can be formed in bath water by reflecting the laser light on fine bubbles. This makes it possible to produce various kinds of light effects on the bathtub water, and the visual relaxation effect is further increased.

  In the second invention, the wavelength of the laser light is 360 nm to 830 nm, and laser light in the range from ultraviolet light to near infrared light centering on visible light enables various light effects.

  In the third invention, for example, by irradiating laser light from above the bathtub, it is possible to project an image on bathtub water that has become clouded by fine bubbles, and the diversity of light effects is further increased.

  In the fourth invention, the human body, particularly the eyeball, is prevented from being irradiated with the laser beam by the human body detecting means.

  The present invention has the features as described above, and the best mode for carrying out the invention will be described below with reference to FIGS.

  FIG. 1 is a side sectional view illustrating an embodiment of a bathing apparatus of the present invention.

  The bathing apparatus illustrated in FIG. 1 includes bubble generating means 2 below the wall surface of the bathtub 1, and a plurality of laser light irradiation means 3 on the wall surface of the bathtub 1. The fine bubbles 4 ejected from the bubble generating means 2 have a diameter of 0.2 μm to 100 μm. The fine bubbles 4 are irradiated with the laser beam 5 from the laser light irradiation means 3 and reflected by the fine bubbles 4 to be linear. Color light is formed.

  As the bubble generating means 2, for example, an apparatus means disclosed in Patent Document 4 can be adopted. That is, the bath water sucked into the pump by the motor drive and the atmosphere are pressurized and dissolved in the pump, rectified by the accumulator, and supplied to the jet outlet. The pressure-dissolved water is depressurized at the jet outlet, passes through the pore cartridge at the jet outlet, and the fine bubbles 4 are jetted into the bath water. By adjusting the degree of pressurization, decompression, rectification, cartridge hole diameter, etc., fine bubbles having a diameter of 0.2 μm to 100 μm are ejected.

  Since the fine bubbles 4 having a diameter of 0.2 μm to 100 μm do not float and disappear for a while after the generation, the linear light by the laser light 5 continues for a long time. However, since the fine bubbles 4 disappear little by little, the fluctuation of the color light by the laser light 5 is affected, and a more complicated visual effect appears.

  A plurality of bubble generating means 2 may be provided at any wall surface location of the bathtub 1. Further, the plurality of bubble generating means 2 may generate the microbubbles 4 having the same size, or may generate the microbubbles 4 having different sizes. Since the microbubbles of different sizes are annihilated at different times, the fluctuation of the color light by the laser light 5 is diversified, and various light effects are possible.

The laser light irradiation means 3 is an apparatus capable of irradiating laser light in a range (wavelength 360 nm to 830 nm) covering the ultraviolet light region to the near infrared light region centering on the visible light region (wavelength 400 nm to 720 nm). Can be used. For example, visible lasers include red semiconductor lasers (AlGalnP, GalnP, AlGaA), green semiconductor lasers (ZnSSe, ZnCdSe), blue semiconductor lasers (InGaN), free electron lasers, OPO lasers, dye lasers, alexandrite lasers, Kr ions A laser, ruby laser, Ti sapphire laser, He-Cd laser, He-Ne laser, copper vapor laser, Nd: YAG double frequency, Ar ion laser, or the like can be used. The laser light 5 emitted by these devices is preferably output class 1, 1M, 2 or 2M according to the International Electrotechnical Commission (IEC) in consideration of the influence on the human body of the bather.

One or more laser light irradiation means 3 are installed on any wall surface of the bathtub 1. As illustrated in FIG. 1, the installation position of the laser beam irradiation means 3 may be a position where the laser beam irradiation unit 3 is immersed in the bathtub water, or the laser beam 5 is irradiated from the upper part of the wall surface of the bathtub 1 to the bathtub water surface. It may be a position. Further, when there are a plurality of laser light irradiation means 3, each may be irradiated with laser light 5 having the same color tone and wavelength, or may be irradiated with laser light 5 having different color tone and wavelength. Further, the laser beam irradiation means 3 may be configured such that the irradiation direction of the laser beam 5 is constant or variable manually or automatically. However, it is preferable that the irradiation direction of the laser beam 5 be lower than the horizontal. When the laser beam 5 is irradiated horizontally or more, there is a risk that the laser beam 5 is irradiated to the bather's eyeball, which is not preferable. Further, various sensors as human body detection means may be connected to the laser light irradiation means 3, and the laser light 5 may be stopped when a human body is detected in the irradiation direction of the laser light 5.

  The laser beam irradiation means 3 can be operated at any time by a manual switch, or can be automatically interlocked with the operation of the bubble generating means 2.

  FIG. 2 is a side cross-sectional view illustrating another embodiment of the bathing apparatus of the present invention.

  In the bathing apparatus illustrated in FIG. 2, the laser beam irradiation means 3 is installed on the ceiling surface 11 of the bathroom 10, and for the fine bubbles 4 ejected from the bubble generation means 2 disposed on the wall surface of the bathtub 1, Laser light 5 is irradiated from above the bathtub. Further, a human body detection means 6 is connected to the laser light irradiation means 3 so that the bather is not directly irradiated with the laser light 5.

Further, when a plurality of laser beams 5 are irradiated from the laser beam irradiation means 3 all at once and with a certain pattern, the bath water which becomes cloudy by the fine bubbles 4 becomes a screen, and an image is projected. At this time, as illustrated in FIG.
The laser beam 5 may be separately irradiated into the bath water. Or you may make it irradiate the microbubble 4 as background light by the lamp | ramp diffused light currently disclosed by patent document 4. FIG.

  Needless to say, the present invention is not limited to the above examples, and various aspects are possible in detail.
