CONSTITUTION:The outside parts of a bathtub receiving board 8 for placing a bathtub 3 and a circulation pump 1 are coated with vibrationproof coating 4, and vibrationproof rubbers 9 and 10 as vibrationproof parts are installed between the circulation pump 1 and the bathtub receiving board 8 and between the bathtub 3 and the bathtub receiving board 8, respectively. The vibration of the bathtub 3 which is generated by the vibration of the circulation pump 1 and the pressure variation of the bubble jet stream is largely reduced by the vibrationproof rubber 9 installed between the circulation pump 1 and the bathtub receiving board 8 and the vibrationproof rubber 10 installed between the bathtub 3 and the bathtub receiving board 8, and only the largely damped vibration is transmitted to the bathtub receiving board 8. The vibration of the bathtub receiving board 8 is further suppressed by the vibration-proof coating 4 applied on the outside of the bathtub receiving board 8, and the generation of resonance due to the slight vibration after the vibrationproof treatment or the pressure of the noise through the aerial transmission is suppressed, and the noise generated from the bathtub receiving board 8 can be reduced remarkably.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a bathtub device in which air bubbles are generated inside the bathtub.

BACKGROUND OF THE INVENTION A conventional bathtub device is shown in FIG. In the figure, a circulation pump 31 circulates water through a pipe 32, and a bubble jet device 36 provided on the wall of a bathtub 35 blows out a jet of bubbles, which is a mixture of water and air, into the inside of the bathtub 35. Here, 33 is a water inlet, 34 is a bubble jet outlet, 37 is a bathtub support, and 38 is a floor of the building.

Problems to be Solved by the Invention In such a configuration, the conventional bathtub device has a problem in that the bathtub 35 vibrates greatly due to pressure fluctuations when ejecting a jet stream containing bubbles. Also, this vibration
The bathtub support was transmitted to the base 37 from the foot portion 39 of the bathtub support 5, and furthermore, the vibration of the circulation pump 31 was simultaneously transmitted to the bathtub support and the base 37, and the vibration of the bathtub support and the base 37 was larger. Furthermore, in order to reduce the weight of the bathtub support base 37, it is designed to be very thin except for the parts where strength is required. Therefore, when even a small amount of vibration from the bathtub 35 is transmitted to the base 37, the thin bathtub support is excited to vibrate resonantly, and it also resonates due to the pressure of sound propagated through the air, and these phenomena cause large noises. was. The vibration of the base 37 of this bathtub receiver generates a large amount of noise both inside and outside the bathroom, and because of this noise, the clarity of conversations in the bathroom and AV equipment such as TV and radio decreases, making it extremely difficult to hear. In addition, there was the problem of so-called household noise, in which the noise was transmitted to the outside and caused a nuisance to neighboring houses.

The present invention is intended to solve such conventional problems, and primarily aims to significantly reduce the vibration noise generated from the bathtub support.

Means for Solving the Problems In order to solve the above problems, the bathtub device of the present invention includes a bathtub, a pipe line for circulating water inside the bathtub, and a circulation pump provided in the middle of the pipe line. a bubble ejecting device installed in the conduit and ejecting a bubble jet by mixing water and air;
The bathtub support on which the bathtub and the circulation pump are placed has a stand, and the bathtub and the bathtub support each have a vibration isolating portion between the stands, and the bathtub support has a stand made of a damping material.

Function: With the above-described configuration, the vibration transmitted from the bathtub or the circulation pump to the bathtub support is attenuated by the vibration isolator. In addition, vibrations caused by air propagation of vibrations and sound pressure are greatly attenuated by the base of the bathtub support made of damping material.

As a result, the bathtub support greatly reduces vibration noise transmitted from the base.

EXAMPLE Hereinafter, an example of the bathtub device of the present invention will be described with reference to FIG.

The bathtub device of the present invention includes a bathtub 3, a pipe line 2 that circulates water inside the bathtub 3, a circulation pump 1 provided in the middle of the pipe line 2, and a pump that circulates water and air in the pipe line 2. The bathtub holder on which the bathtub 3 and the circulation pump 1 are placed has a stand 8, and the outside of the stand 8 of the bathtub holder is coated with a damping paint 4. There are vibration isolating rubber parts 9 between the circulation pump 1 and the bathtub holder and between the bathtub 3 and the bathtub holder 8, respectively. and anti-vibration rubber 10 are provided. Here, 5 is a bubble jet outlet, 7 is a floor of the building, 11 is a water inlet, and 12 is a water suction side pipe.

In such a configuration, vibrations of the circulation pump 1 and vibrations of the bathtub 3 caused by pressure fluctuations of the bubble jet are caused by the vibrations of the circulation pump 1.
The vibration of the bathtub holder is greatly reduced by the vibration isolating rubber 9 installed between the pedestal 8 and the vibration isolating rubber 10 installed between the bathtub 3 and the pedestal 8. I can only convey it. The vibration damping paint 4 applied to the outside of the base 8 of the bathtub support further suppresses the vibrations of the base 8, and even slight vibrations after vibration isolation or the pressure of sound due to air propagation will not resonate. As a result, the noise generated from the bathtub support platform 8 is significantly reduced.

In addition, even if the water inside the bathtub 3 (i.e., water containing bath materials, chlorine, or ammonia) flows onto the base 8 of the bathtub support, the damping paint 4 is applied to the outside of the base 8 of the bathtub support. I never touch this water. Therefore, there is no need to worry about the reliability of the medicine.

Furthermore, the damping paint 4 increases the heat insulation properties of the base 8 of the bathtub support, thereby preventing a drop in the temperature of the hot water inside the bathtub 3.

It is well known that the same vibration damping effect can be obtained even if the bathtub support base 8 is constructed using a damping steel plate, which is often used as a damping material. Furthermore, expanding on the above concept, the bathtub support uses vibration-damping steel plates not only for the base but also for the wall materials that make up the bathroom, improving vibration damping properties and reducing noise inside and outside the bathroom. can do.

By reducing these vibrations in this way, it is possible to significantly reduce the vibration noise generated inside and outside the bathroom, improving the clarity of conversations and AV equipment in the bathroom, and making bathing more comfortable. In addition to being able to enjoy the environment, there is no need to worry about household noises bothering neighbors, etc.

Furthermore, since the bathtub support greatly reduces the vibration of the base 8, the propagation of vibrations to the floor of the building where the bathtub 3 is installed is also reduced. As a result, even if a bathtub equipped with a bubble ejecting device is installed on the second floor or above of an apartment complex, the user can take a bath without disturbing the downstairs or neighboring rooms with noise.

Effects of the Invention As described above, according to the bathtub device of the present invention, the vibration isolating part and the bathtub support suppress the vibrations transmitted to the base from the bathtub or circulation pump and the vibrations due to air propagation of sound pressure. significantly suppressed by gender. Therefore, the vibration noise transmitted from the bathtub support to the floor and walls of the building is greatly reduced. Therefore, the user can enjoy AV equipment such as television and radio in the bathroom, and can enjoy bathing without bothering the outside of the bathroom or the surrounding area with these everyday noises. Furthermore, since the damping material does not come into direct contact with the water inside the bathtub, the reliability of the damping material is high. Furthermore, due to the heat insulating effect of the damping paint applied to the vibration damping material, there is an energy saving effect in that the temperature of the hot water inside the bathtub decreases less.
