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 perform pine surges on the body, thereby increasing the bathing window.

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

With this configuration, by operating the circulation pump, bath water can be spewed out from the spout on the side wall of the bathtub body, and at the time of spouting, air is sucked under negative pressure from the air suction part and poured into the bath water. By mixing air and ejecting 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 high frequency component generated during the switching operation of the switching element causes the connection between the bathtub and the V & ring pump to be controlled. If the insulation is not sufficient, current will leak to the bathtub side, increasing the risk to the human body.

Furthermore, since Impark is still expensive, the bubble generating bathtub is 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, and 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. In a bubble-generating bathtub that can spout bath water, a variable flow rate valve is installed in the forced bath water flow path, and the variable flow rate valve is fixedly attached to the forced bath water flow path with a fixed plate with holes. , a bubble-generating bathtub comprising a movable plate with holes slidably abutting a fixed plate with holes, and a plate rotation device that rotates the movable plate with holes relative to the fixed plate with holes. This is related to.

(E) Functions and Effects In the present invention, the movable plate with holes is rotated relative to the fixed plate with holes provided in the forced bath water flow path of the bath water circulation flow path by driving the plate rotating device. By simply adjusting the amount of alignment between the holes in both plates, the amount and pressure of the hot water jet can be easily changed as desired, allowing bathers to enjoy various types of blowing.

In addition, the variable flow valve having such a configuration is extremely simple in configuration, and can be driven and controlled by an inexpensive electric motor and control means, so an expensive inverter can be eliminated and bubbles can be generated. A bathtub can be manufactured at low cost.

In particular, since the rotational force of the plate rotation device can be directly used to rotate the movable plate with holes, the configuration of the plate rotation device can be simplified and manufactured at low cost.From this point of view, the bubble generating bathtub can be manufactured at low cost. It can be manufactured.

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.
