JPH0318361A - Bubble generating bathtub to smoothly change form of jet stream - Google Patents

Abstract

PURPOSE:To enjoy the various forms of jet streams for a bathing person by controlling the opening/closing degree of an ejecting nozzle and the rotating speed of a circulating pump, obtaining the various forms of the jet streams with various ejecting quantity and ejecting pressure and making the strength of the jet stream almost equal when the form of the jet stream is changed to the other form of the jet stream. CONSTITUTION:By controlling the opening/closing degree of respective ejecting nozzles 2, 3 and 4 through a control part C, a field blow can be obtained to be alternatively changed to mild blow, for which the ejecting quantity of bathing hot water from the respective ejecting nozzles 2, 3 and 4 is large and the ejecting pressure is low, and a finger-pressure blow for which the ejecting quantity of the bathing hot water from the respective ejecting nozzles 2, 3 and 4 is small and the ejecting pressure is high. However, when the mild blow and finger-pressure blow are alternatively changed, the strength of the jet stream is made almost equal for the mild blow and finger- pressure blow and the both blows can be smoothly linked by controlling the rotating speed of a circulating pump P through the control part C. In such a case, the rotating speed of the circulating pump P is controlled through an inverter 1 by the control part C and can be smoothly changed without fail.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bubble-generating bathtub in which the form of jet flow can be smoothly changed.

(Exposure) Conventional technology In the past, as an example of a bubble-generating bathtub, a bath water circulation flow path was interposed between a bathtub body and a circulation pump, and an air intake part was connected to the bath circulation flow path. , a control valve is provided in the middle of the air intake pipe connected to the air intake section to enable the bubbly bath water to be spouted into the wooden body of the bathtub, and the control valve adjusts the amount of air intake. There is a system in which it is possible to obtain a jet stream with a desired jet pressure by adjusting the amount of air blower and changing the jet pressure of the bath containing air bubbles.

(c) Problems to be solved by the invention In the case of the above-mentioned bubble-generating bathtub, the ejection pressure of the bath water can only be changed by adjusting the amount of intake air;
The bath water was in the form of a jet stream similar to iB.

Moreover, the jet pressure must be adjusted manually; if the jet pressure is changed suddenly, the strength of the jet flow felt by the bather will change dramatically, causing discomfort to the bather. In order to avoid such discomfort, the ejection pressure must be adjusted slowly, which is a hassle.

(2) A final step to solve the problem. Therefore, in the present invention, a bathtub circulation flow path consisting of a bath water suction flow path and a bath water forced flow path is interposed between the bath 10 main body and the circulation bomb. The end of the forced bath water flow path is opened in the bathtub body to form a spout nozzle, and an air intake part is connected in communication with the forced bath water flow path, so that the end of the forced bath water flow path is connected to the bathtub body from the spout nozzle. In the bubble-generating bathtub configured to be able to spray bubbles mixed into the bathtub, the opening/closing amount of the spray nozzle and the rotation speed of the circulation pump described in "2" can be controlled via the control unit, and the spray amount and spray pressure can be controlled. If we obtain regular or irregular changes in the various jet forms over time, then J (abbreviates the jet strength of different jet forms when changing from one jet form to another) To provide a bubble-generating bathtub in which the shape of the jet stream can be smoothly changed, and is characterized in that the connection can be made smoothly.

In addition, by controlling the amount of opening and closing of the spout nozzle via the control unit, it is possible to create a mild blow that has a large amount of hot water spouted from the spout nozzle and a low spout pressure, and a mild blow that has a small amount of hot water spouted from the spout nozzle and has a low spout pressure. When the jet pressure is alternately changed over time to a high acupressure blow, the jet strength of the mild blow and the acupressure blow can be controlled by controlling the rotation speed of the circulation pump via the control unit when changing the jet pressure. Another feature is that they are made almost the same, allowing for loose connections.

(e) Action/effect According to the present invention, the following effects are produced.

That is, by controlling the opening and closing of the jet nozzle via the control unit, various types of jets with different jet amounts and jet pressures can be created, for example, a mild blow with a large amount of bath water jetted from the jet nozzle and a low jet pressure. When changing over time to Shiatsu blowing, which has a small amount of bath water spouted from the 11I1 nozzle and a high jetting pressure, the rotation speed of the circulation pump is changed to Jl<. By controlling the jet strength of the mild blow and the acupressure blow, the jet strength is made almost the same, allowing for a gentle connection.
Bathers can enjoy jets of different shapes, and can fully enjoy the comfort of playing in the waves generated by the jets without feeling discomfort when the jets change shape.

As mentioned above, in this example, in Feelbro,
When changing the mild blow and the acupressure blow, the rotation speed of the circulation pump (P) is controlled by the control unit (C), so that the jet strength of the mild blow and the acupressure blow are made the same, and the field Because the blows can be connected gently, bathers can enjoy the stimulating massage effect of a mild blow and the acupressure effect of a shiatsu blow. You can enjoy the comfort of playing in the waves generated by the jet without feeling any discomfort when changing to the shiatsu blow.

In addition, in this embodiment, the mutual change between mild blow and acupressure blow at the field blow mouth can be smoothly performed, but when changing the jet flow form other than field blow, the circulation pump (P) is rotated. The number of inverters (1
), the jet strength can be changed gradually, and the jet form can be smoothly changed without causing discomfort to the bather.

Furthermore, depending on the preference of the bather, the strength of the jet stream can be changed in a disruptive manner, thereby stimulatingly changing the shape of the jet stream.
