Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bubble-generating bathtub that is highly safe during bathing and allows inexpensive blow control.

(B) Conventional technology Conventionally, as one form of bathtub, there is a bubble-generating bathtub that is equipped with a bubble-generating device separate from the bathtub body, and the bubble-generating bathtub uses the bubble-generating device to generate bubbles in the bathtub. As a result, the air bubbles can be used to massage the body, increasing the pleasure of bathing.

That is, such a bubble-generating bathtub is provided with a spout on the side wall of the bathtub body, and bath water is circulated through the spout via a circulation pump. A ring pump is connected in communication, and an air suction part is installed near the spout, which can mix air into the bath water using an ejector effect.

With this configuration, by operating the N-ring pump, bath water can be spouted from the spout on the side wall of the bathtub body, and at the time of spouting, air is suctioned under negative pressure from the air suction part, so that the water can flow into the bath water. By mixing air into the bathtub and ejecting the air-mixed bath water from the spout, bubbles are generated in the bathtub and applied to the body of the bather, thereby increasing the pine surge effect.

In recent years, as described in Utility Model Application No. 63-100035, the ejection force of bath water can be changed periodically by controlling an electric motor used as a pump drive device for driving a circulation pump using an inverter. There are also proposals that can be made.

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

That is, in the above-mentioned bubble-generating bathtub, when the electric motor is controlled by an inverter in order to change the spouting amount and jetting pressure of bath water, the insulation between the bathtub and the circulation pump is caused by the high frequency components generated during the switching operation of the switching element. If this is not done properly, the leakage current will flow to the bathtub side, increasing the danger to the human body.

Furthermore, since inverters are still expensive, bubble generating bathtubs are also expensive.

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

(d) Means for Solving the Problems The present invention provides a bath water circulation flow path consisting of a bath water suction flow path and a bath water forced flow path between the bathtub body and the circulation pump. An air intake part is connected to the hot water forced flow passage, and the air taken in by the air intake part is mixed into the bath water in the bath water forced flow passage, and air bubbles are mixed into the bathtub body from each jet nozzle. This invention relates to a bubble-generating bathtub capable of spouting bath water, characterized in that a variable flow rate pulp is disposed in a bath water suction channel.

Further, the present invention provides variable flow rate pulp at the suction port, and drives the plate rotating device to rotate the variable flow rate pulp relative to the fixed plate with holes provided at the suction port. By adjusting the amount of alignment of the through holes in both plates, the amount and pressure of the bath water are controlled.
1 is also featured in the configuration that enables it.

(E) Functions and Effects In the present invention, a variable flow rate pulp is provided in the bath water suction flow path, particularly in the suction port, and by adjusting the opening/closing amount of the valve, the jetting amount and jetting pressure can be easily adjusted. This allows bathers to enjoy various types of blowjobs.

In addition, the variable flow rate pulp has an extremely simple structure and can be driven and controlled by an inexpensive electric motor and control means, so there is no need for an expensive inverter that is required to control the ejection amount and ejection pressure using a circulation pump. Therefore, the bubble generating bathtub can be manufactured at low cost.

Furthermore, it is possible to change the blow mode without performing inverter control, and the possibility of life-threatening electric shock accidents caused by high frequency components can be reduced as much as possible.

In addition, since the flow rate is variable on the upstream side of the circulation pump, there is no need to use pressure-resistant parts for the circulation pump or piping, etc. In other words, synthetic oil products such as plastic can be used, so it is possible to reduce the cost by integrally molding. It can be manufactured. Moreover,
It can have excellent corrosion resistance.

Furthermore, since the variable flow rate pulp is on the pressure receiving side, the valve driving torque can be small, and therefore the driving source can be made smaller, that is, the motor etc. can be made smaller and cheaper.
