Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to a bubble generating bath tub which can be changed in blow form, can be manufactured at low cost, and has high safety.

(B) Conventional technology Conventionally, as one form of a bathtub, there is a bubble generating bathtub provided with a bubble generating device separately from a bathtub body, and the bubble generating bathtub generates bubbles in the bathtub by the bubble generating device. By doing so, massage the body with bubbles,
It is configured so that a feeling of taking a bath can be enhanced.

That is, such a bubble-generating bathtub is provided with a spout on the side wall of the bathtub body, a circulating pump for circulating bath water through the circulating pump is connected to the spout, and an ejector effect is provided near the spout. An air suction unit that allows air to be mixed into the bath water is installed by utilizing this.

With this configuration, by operating the circulation pump, the bath water can be spouted from the spout on the side wall of the bathtub body, and at the time of the spout, the air is suctioned at a negative pressure from the air suction unit, and the bath water is injected into the bath water. By mixing air and jetting out hot water mixed with air from the jet port, air bubbles are generated in the bath tub and applied to the bather's body, thereby improving the massage effect and the like.

(C) Problems to be Solved by the Invention However, the above-mentioned bubble generating bath still has the following disadvantages.

That is, in the above-described bubble generating bath, only one circulation pump used for circulating bath water is provided in the bath water suction flow path. The bath water could only be spouted into the bathtub with the spout pressure, and the jet flow was monotonous.

In particular, it was not possible to secure a sufficient ejection pressure in terms of the ejection pressure, and the massage effect was insufficient.

On the other hand, in order to ensure a high ejection pressure, the pump capacity must be significantly increased, and such a pump has become large, heavy, and expensive.

In addition, when the circulating pump breaks down, there is a problem that it is impossible to take a bath until the repair / replacement work is completed.

As described in Japanese Utility Model Application Laid-Open No. 63-100035,
Inverter-controlled electric motors have also been developed to change the amount and pressure of the bath water.

However, such electric motors are expensive because they require high-level control such as inverter control, and the product cost of the bubble generating bath itself is also high. Also, in terms of safety, high frequency components generated during operation cause problems. Had.

 Also, the ejection pressure has not been sufficient.

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

(D) Means for Solving the Problems The present invention provides a bath water circulation flow path comprising a bath water suction flow path and a bath hot water supply flow path between a bathtub body and a circulation pump. An air intake section is connected to the hot water supply channel and air taken in by the air intake section is mixed into the bath water in the hot water supply channel, and air bubbles are mixed into the bathtub body from each jet nozzle. In the bubble-generating bath tub in which the bath water can be spouted, a plurality of circulating pumps are arranged in parallel in the bath tub circulation path so that the spouting form from the spout nozzle can be appropriately changed, and the operating state of the circulating pump The present invention relates to an air bubble generating bath provided with a control device capable of changing.

(E) Function and effect In the present invention, since a plurality of circulation pumps are arranged in parallel in the bathtub circulation flow path, even if the circulation pump is a fixed-quantity pump, the number of operations of the same pump may be changed as appropriate. Thus, the ejection amount and ejection pressure of the circulation pump can be easily changed, and a plurality of blow modes can be enjoyed.

In addition, since an inexpensive small pump is sufficient, the overall weight can be reduced, and the number of installations can be arbitrarily determined according to the application.

Furthermore, the blow mode can be changed simply by simply turning on and off each circulation pump, so that the control unit of the circulation pump can be manufactured at low cost, and the bubble generation bath can be manufactured at low cost.

Furthermore, since a plurality of circulation pumps are used, even if one of them fails, another circulation pump can be used, so that bathing is not hindered, and replacement of the circulation pump is easy, and In addition, the cost required for replacement can be reduced.
