DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bubble-generating bathtub that can perform wave blowing in time with the sound of waves.

(b) Conventional technology Conventionally, as a basic form of a bubble-generating bathtub, Japanese Patent Laid-Open No. 59-1
As described in Japanese Patent No. 35058, a bath water suction pipe and a bath water supply vibrator are connected between the bathtub body and the circulation pump, and an air intake part is provided in the middle of the pipe.

With this structure, the circulation pump is operated and the pump sucks the bath water inside the bathtub body through the bath water suction pipe.
Then, the water is ejected from the pump into the bathtub body via the bathwater supply pipe.

At this time, the air intake part mixes the bath water into the bath water by using the negative pressure generated by the jet of bath water from the air intake part. I'm trying to make it squirt out.

(c) Problems to be Solved by the Invention However, the above-mentioned bubble-generating bathtub had the following drawbacks.

That is, since such a circulation pump is driven at a constant rotation speed, the amount and pressure of the bubble-mixed bath water jetted from the jet nozzle were always constant.

Therefore, even if this bath water is applied to the bather's body, it only has a stimulating effect on the body, and since it relies on the tactile function of the five human senses, the stimulation will be monotonous, and the bather will not be able to enjoy the bath. I couldn't improve my feelings.

Furthermore, when the jet pressure from the jet nozzle is increased, the jet hits one part of the body, causing pain and discomfort to the bather, making it impossible to take a bath for a long time.

An object of the present invention is to provide a bubble-generating bathtub that can solve the above problems.

A bubble-generating bathtub constructed to be able to eject water, comprising an output part capable of outputting wave sound, and a control part controlling a drive circuit of a circulation pump that spouts out wave-shaped bath water based on the output of the wave sound. The present invention provides a bubble-generating bathtub with special features.

Further, the present invention is characterized in that the wave sound is composed of a plurality of wave sound patterns such as rocky sound, sandy beach sound, etc.

Furthermore, the present invention is characterized in that the output section is provided with a selection means that allows selection of wave sound patterns such as rocky sound, sandy beach sound, etc.

Further, in the present invention, there is provided a selection means that can select a wave sound pattern such as the sound of a rocky area or a sound of a sandy beach, and based on a signal from the selection means, the output of each wave sound from the output section and the output of each wave sound of each wave-like bath water. It is characterized by comprising a control section that controls a drive circuit of a circulation pump that performs ejection.

(e) Functions and Effects In the present invention, the circulation pump is operated to circulate the bath water within the bathtub body, thereby spouting the bath water from the spout nozzle, and at that time, the air sucked from the air intake part. can be mixed into the bath water in the bath water forced flow channel to obtain a jet stream mixed with air bubbles.

Furthermore, the output section selects a wave sound pattern such as the sound of a rocky area or the sound of a sandy beach, and outputs that sound.The output also controls the drive circuit of the circulation pump, making this jet flow mixed with bubbles into a wave shape that can be applied to the body. By applying it to the desired location, you can enjoy the pine surge effect of acupressure or other jet pressure.

As described above, according to the present invention, each wave sound is outputted by the output section, and the rotation speed of the circulation pump is controlled by each wave sound, so that the effect of the sound of the waves and the wave-like spout of bath water can be used to improve human health.
