BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub device for ejecting air bubbles into the interior of a bathtub.

0002

2. Description of the Related Art A conventional bathtub device will be explained with reference to FIG.

[0003] In FIG. 3, a bathtub is circulated by a circulation pump 1, and when the bathtub passes through a bubble jetting device 2, a jet containing air bubbles is jetted out from an outlet 3 of the bubble jetting device 2. Here, 4 is a pipe that introduces bath water into the circulation pump 1, 5 is a pipe that connects the circulation pump 1 and the bubble ejecting device 2, 6 is a bathtub, 7 is a foot of the bathtub, and 8 9 is a bathtub holder, 9 is a foot of the bathtub holder, 10 is a circulation pump foot, and 11 is a floor on which the bathtub holder 8 is installed.

0004

[Problems to be Solved by the Invention] However, in such a configuration, the pipe line 4 for introducing bath water into the circulation pump 1,
The circulation pump 1 and the bubble ejecting device 2 must be connected by a pipe 5, and a pressure loss occurs when passing through the pipes 4 and 5, so that the bubble jet is weakened. Another problem is that during construction, two holes are drilled in the bathtub for each bubble ejecting device and piping is installed, which requires a lot of effort.

Furthermore, when the circulation pump 1 is driven to operate the bubble ejecting device 2, the vibrations of the bathtub pedestal 8 that are excited by the vibrations generated from the circulation pump 1 and the vibrations generated from the bubble ejecting device 2, It is transmitted to the floor 11 via the bathtub pedestal foot 9. Therefore, if the bathtub device is installed on the upper floor of a housing complex and the bubble blowing device 2 is operated, the noise in the downstairs room becomes louder, causing a problem of causing a great deal of trouble to neighboring residents.

[0006] The present invention solves these conventional problems, and its primary purpose is to significantly reduce the labor involved in construction and to obtain a strong bubble jet.

A second object is to provide a bathtub device that can suppress vibration noise transmitted to the downstairs room even when the circulation pump is driven and the bubble blowing device 2 is operated.

[0008]

[Means for Solving the Problems] In order to achieve the first object, the bathtub device of the present invention includes a bathtub, a circulation pump that circulates water in the bathtub, and a circulation pump that is installed in the outlet passage of the circulation pump and that is installed inside the outlet passage. an air supply means for supplying air to the air, and a suction passage for a circulation pump that is close to the jet passage and is provided so as to flow in the opposite direction to the flow of water flowing through the jet passage, and the jet passage and the suction passage are They are connected or integrally formed and placed on the outer surface of the bathtub.

Further, in order to achieve the second object, the present invention provides a bathtub holder on which a bathtub is placed, a bathtub foot provided on the bathtub, and vibration isolation means between the bathtub foot and the bathtub holder. It has been established.

0010

[Operation] Due to the above-described structure, the bathtub device of the present invention has a small pipe resistance and a strong bubble jet. The work of piping the bathtub and circulation pump during construction is greatly reduced. The time required for construction can be drastically reduced.

Furthermore, the vibrations generated from the circulation pump and the vibrations generated from the bubble ejecting device are once transmitted to the bathtub, but are damped by vibration isolating means provided at the foot of the bathtub.

0012

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, the same components as those of the conventional bathtub device shown in FIG. 3 will be described with the same reference numerals.

FIG. 1 shows a bathtub device in one embodiment of the present invention. In the figure, bubble ejecting devices 13 incorporating a circulation pump 12 for circulating bath water in the bathtub 6 and ejecting bath water and bubbles are provided on opposite sides of the shorter sides of the bathtub 6. Also, a bathtub pedestal 8 on which the bathtub 6 is placed,
A bathtub foot portion 14 provided in the bathtub 6 is provided. A vibration isolating rubber 15 is provided between the bathtub foot 14 and the bathtub holder 8 as a vibration isolator made of ethylene propylene (hereinafter abbreviated as EPDM).

Here, as shown in FIG.
A circulation pump 12 is provided at the rear end portion 16 of. Moreover, the inside of the bubble ejecting device 13 has a structure in which a flow path is divided into two upper and lower parts, which are used for both purposes, and the lower flow path serves as a suction path 17 from the bathtub 6 to the circulation pump 12. The upper flow path is a blowout path 18 from the circulation pump 12 to the bathtub 6, and air is sucked in from an air suction path 19, which is an air supply means, to generate a bubble jet. For this reason, only one hole is required to be drilled into the bathtub 6 for one bubble ejecting device.

The operation of the above configuration will be explained below. By driving the circulation pump 12, the bath water in the bathtub 6 passes through the suction path 17 in the bubble ejecting device 13 and is sucked into the circulation pump 12, and the bath water pressurized by the circulation pump 12 passes through the suction path 17 in the bubble ejecting device 13. 13, negative pressure is generated by the diffuser 20 and the air is passed through the air intake path 1.
9 and blows out a jet of bubbles into the bathtub 6. At this time, vibrations are generated from the circulation pump 12 and the bubble ejecting device 13. The generated vibrations both vibrate the entire bathtub 6, but since the vibrations of the excited bathtub 6 are damped by the vibration isolating rubber 15, transmission of the vibrations to the bathtub pedestal 8 can be suppressed.

As described above, according to this embodiment, since the circulation pump 12 is built into the bubble jetting device 13, the pressure loss of the bath water when passing through the suction passage 17 and the jetting passage 18 can be reduced, and a strong jet stream can be generated. can be supplied toward the inside of the bathtub 6. In addition, the labor involved in constructing piping can be greatly reduced, and there is less worry about water leaks.

Furthermore, a circulation pump 12 and a bubble blowing device 13 are provided.
The vibrations generated from the bathtub 6 vibrate the bathtub 6, but the vibrations of the bathtub 6 are damped by the anti-vibration rubber 15 and are not easily transmitted to the bathtub pedestal 8, so that the transmission of vibrations to the floor 11 can be kept to a minimum. . This reduces the vibration noise transmitted to the downstairs rooms of apartment buildings, etc., and allows nearby residents to enjoy the bubble jetting device without worrying about it.

Here, the material of the vibration isolating rubber 15 is EPDM, but since this is used at the lower part of the bathtub foot 14, it has poor durability against bath water and chemicals (hypochlorous acid, etc.). This is because we selected a material with a certain EP used this time
Even anti-vibration rubbers other than DM exhibit similar anti-vibration effects. In the embodiment, the bubble ejecting devices 13 are provided at two locations in the bathtub 6, but substantially the same effect can be produced even if the bubble ejecting devices 13 are provided at only one location or three or more locations.

[0019]

[Effects of the Invention] As described above, the bathtub device of the present invention provides the following effects. The suction passage and the discharge passage of the circulation pump are connected or integrally formed and are directly attached to the outer surface of the bathtub, so that bath water can be introduced into the circulation pump by bypassing the outer circumference of the bathtub as in the past. Long pipes are not required. This reduces pressure loss and allows a strong jet to be supplied to the bathtub. Further, since it is only necessary to make one hole in the bathtub to communicate the suction passage and the spout passage with the bathtub, the labor during construction is greatly reduced, and there is less worry about water leakage, etc., and reliability is improved.

Furthermore, although the vibrations generated by the circulation pump and the bubble ejecting device vibrate the bathtub, these vibrations are damped by the vibration isolating means and hardly transmitted to the bathtub holder. Therefore, the vibration noise transmitted to the downstairs room of an apartment complex or the like is reduced, so that nearby residents can enjoy the bathtub device with bubble jetting without worrying about it.
