Here, 27 is an air suction pipe, 28 is a water surface, 30 is a bathroom bottom plate, 32 is a bathroom foot, 33 is a circulation pump mounting part, and 34 is a floor.

Problems to be Solved by the Invention With such a configuration, in the conventional bubble jet bathtub device, when water is supplied to the bathtub from the faucet, water enters the pipe from the suction port, and at the same time, it also flows out from the spout. Water is coming in. As a result, an air pocket is created in a part of the circulation pipe. If you operate the bubble ejector in this state,
The air trapped inside the pipe is forced out from the spout. The emitted noise at this time vibrates the walls of the bathtub and bathroom,
There was an issue with extremely high noise levels.

Moreover, the ejection noise of such a bubble ejecting device is very large even during steady operation. In particular, the problem is that the vibration noise from the circulation pump and the air bubbles being ejected is transmitted to the bottom plate and floor of the bathroom and reverberates inside the bathroom, resulting in extremely loud noise, and that the noise is often transmitted to neighboring residences, especially the downstairs rooms of apartment complexes. However, there was a problem in that it caused a great deal of trouble to the residences downstairs.

The present invention solves such conventional problems, and has a structure that does not create air pockets in the circulation pipe, and has a primary purpose of significantly reducing the noise when starting the operation of the bubble ejecting device. It is said that In addition, the second objective is to suppress the vibration noise and bubble ejection noise of the circulation pump even during steady operation to prevent them from being transmitted to neighboring residences, especially the downstairs rooms of apartment complexes.
The purpose is to Thirdly, the purpose is to save space by placing the circulation pump on a bathtub holder, and fourthly, by installing the circulation pump in a position that does not face the water faucet, safety is improved. The purpose is to improve.

Means for Solving the Problems In order to achieve the first object, the present invention for solving the problems described above includes a pipe in which water is circulated by a circulation pump and a suction port of the pipe on the wall surface of the bathtub; A bubble ejecting device and a blowout port of the bubble blowing device are installed at the most downstream position of the pipe line, and the installation height is set in the order of the suction port, the suction port of the circulation pump, the discharge port of the circulation pump, and the bubble jet port. The piping was configured so that the temperature gradually increased.

In order to achieve the second objective, a vibration isolator is installed below the foot of the circulation pump, and a vibration isolator is installed under the foot of the bathroom bottom plate that receives the bathtub.

In order to achieve the third objective, a pipe line through which water is circulated by a circulation pump, a bubble ejecting device that mixes water and bubbles and ejects the mixture, and a bathtub equipped with the pipe line and the bubble ejecting device. The bathtub holder on which the circulation pump and the bathtub are placed is provided with a stand.

Furthermore, for the fourth purpose, a circulation pump is installed in a space surrounded by the side surface of the bathtub, the handrail portion, and the wall surface of the bathroom other than the side surface of the bathtub in contact with the wall surface where the water faucet is installed in the bathroom.

Operation According to the above-described structure of the present invention, when water is supplied, water enters the circulation pipe in order from the suction port and finally reaches the spout. Therefore, no air pockets are generated, and the water circulates smoothly and a jet of bubbles is ejected when the bubble ejecting device starts operating, so that the generated noise can be significantly reduced.

In addition, the vibration noise of the circulation pump is not transmitted to the bottom of the bathroom due to the vibration isolating device installed at the foot of the bathroom, and the sound of bubbles is not transmitted to the floor due to the vibration isolating device installed at the foot of the bathroom bottom board. This makes it possible to significantly reduce noise. In addition, the bathtub receiver can save space by placing the components on a stand, and by removing the circulation pump from directly below the water faucet, it is possible to prevent electrical leakage and improve safety. It is.

EXAMPLE Hereinafter, an example of the bubble jet bathtub device of the present invention will be described with reference to FIGS. 1 and 2.

As shown in the first part, the bubble jet bathroom device of the present invention includes a pipe 2 through which water is circulated by a circulation pump 1, a suction port 5 of the pipe on the wall surface 4 of the bathtub 3, and a suction port 5 of the pipe at the end of the pipe. A bubble ejecting device 6 and a blowing lower of the bubble blowing device are provided at a downstream position, and the installation height is set in the order of the suction port 5, the suction port 8 of the circulation pump, the discharge port 9 of the circulation pump, and the blowing lower of the bubble jet. The piping was configured so that the temperature gradually increased. The circulation pump and the bathtub are placed on a bathtub pedestal 47, and the circulation pump is installed in a space between the wall surface 46 where the water tap is installed, the opposite wall surface 45, and the bathtub handrail section 48. And so. Here, 10 is a water faucet, 11 is a water surface, 12 is an air intake pipe, 13 is an air intake port, I4 is a floor, 1
5.16 is a vibration isolator, 17 is a bottom plate foot, and 18 is a pump foot.

In this configuration, when water is supplied from the faucet, the water enters the circulation pipe in order from the suction port located at the bottom of the bathtub, the water level gradually rises, and finally reaches the spout. do. Therefore, no air pockets occur in the circulation pipe, and the water circulates smoothly and a jet of bubbles is ejected even when the bubble ejecting device starts operating, so the noise generated when the bubble ejecting device starts operating can be significantly reduced. This is possible.

When starting up the bubble ejecting device, the control circuit controls the circulation flow rate of the circulation pump to gradually increase. For example, in a control that repeats on and off intermittently, the on time is shortened and the off time is lengthened at the beginning of startup, and then the on time is gradually lengthened and the off time is shortened. By controlling the pump speed, the rotation speed of the pump gradually increases to the rated speed.At this time, small air bubbles that have accumulated inside the pump are flushed out at low flow rates, and only water is circulated smoothly at rated flow rates. . Therefore, the noise at the time of startup can be suppressed, and a bubble jetting bathtub device with even lower noise can be achieved.

Further, even when water is drained, no water remains in the circulation pipe, so there is an effect that freezing in winter and cracking of pipes due to freezing do not occur.

In this way, by significantly reducing the noise generated when the bubble ejecting device is activated, it is possible to eliminate the nuisance caused by neighboring noises and create a comfortable living environment. Moreover, there is an effect that the bubble jet bathtub device can be installed in an apartment complex or a living space on the second floor or higher.

Next, explanation will be given using FIG. 2. The foot part of the bottom plate of the bathroom includes a threaded part 17, a hexagonal NAND part 19, and a spherical lowermost end 44.
It consists of The vibration isolator has an uneven surface 43 at the bottom.
It consists of a vibration isolating rubber 16 provided with a vibration isolating rubber and a vibration isolating table 42 provided with an undulating portion 41 around the periphery, which is installed on the vibration isolating rubber.

In such a configuration, in order to hold the bathroom bottom plate horizontally, the height of each part is adjusted by rotating the neck part of the bottom plate foot part. In this case, since the lowest end of the foot is spherical, the contact area with the vibration isolator installed at the bottom is small, and the force that twists the vibration isolator in the direction of rotation of the screw is reduced. It is possible to minimize distortion and maximize the anti-vibration effect.

An undulating portion is provided around the vibration isolating table so that the feet will not come off the vibration isolating table. moreover,
The bottom surface of the anti-vibration rubber is uneven, which reduces the contact area with the floor and increases the anti-vibration effect.
Distortion in the twisting direction can be absorbed by these uneven parts, increasing the vibration-proofing effect and improving durability.

In addition, as shown in Figure 1, by installing the circulation pump in a dead space far from the water faucet, space can be saved, and in terms of construction, the piping between the circulation pump and the bathtub can be shortened. No need for extension piping construction, saving labor.

Furthermore, it is possible to prevent electrical leakage from the circulation pump due to water leakage around the water faucet, making it extremely safe.

In this way, the vibration isolating device installed at the bottom of the circulation pump foot and bottom plate foot prevents noise and vibration from being transmitted to the bathroom bottom plate and floor, making it possible to significantly reduce noise inside and outside the bathroom. be. In addition, the vibration isolating device below the circulation pump raises the pump position and has the effect of preventing water from flooding the pump.

Effects of the Invention As described above, according to the bubble jetting bathtub device of the present invention, air pockets do not occur when water is supplied, and water circulates smoothly and a jet of bubbles is ejected when the bubble jetting device starts operating. Not only can the generated noise be significantly reduced, but since no water remains when draining water, there is no problem caused by freezing.

In addition, the vibration isolating device installed at the bottom of the circulation pump foot and bottom plate foot prevents noise and vibration from being transmitted to the bathroom bottom plate and floor, greatly reducing noise inside and outside the bathroom. Even in a crowded room, you can comfortably enjoy a bubble jet bath without worrying about noise issues.

The built-in circulation pump saves space and labor, and by moving it away from the water tap, it has the effect of preventing electrical leakage and improving safety.
