Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a bubble-generating bathtub that adjusts the temperature of the bath water by controlling the amount of bubbles in the bath water.

(b) Conventional technology Conventionally, bubble-generating bathtubs have a bathwater circulation flow path consisting of a bathwater suction pipe and a bathwater continuous pipe between the bathtub body and a circulation pump installed outside the bathtub body. There are some that have an air intake section installed midway through the bath water continuous pipe. and,
The bath water in the bathtub body is sucked through a bath water suction vibrator by a circulation pump, and the bath water is passed through a bath water continuous pipe and squirted into the bathtub body from the discharge part of the same pipe. In addition, the air intake is mixed with the air sucked into the bath water that is spouted out using the negative pressure caused by the hot water jetting out, so that the air is mixed with air bubbles and is spouted out. There is a system in which a regulating valve is provided in the middle of the connected air suction pipe, and the regulating valve adjusts the amount of air suction to change the ejection pressure of the bubble-containing bath water.

(C) Problem to be Solved by the Invention However, since the bubble generation bathtub described above uses a valve to adjust the amount of intake air, while the bather is in the bubble bathtub spewing out bath water mixed with bubbles, In some cases, the temperature of the bath water gradually decreased. Therefore, there has been a desire for a system that can adjust the temperature of the bath water by adjusting the amount of intake air.

(d) Means for Solving the Problems In the present invention, a bath water circulation system consisting of a bath water suction channel and a bath water drying forced flow channel is provided between the bathtub body and a circulation pump installed outside the bathtub body. A flow path is provided, and a plurality of terminal ends of the bath water suction flow path are opened into the bathtub body to form a jet nozzle, and an air intake portion is connected in communication with the bath water supply flow path to form a jet nozzle. In a bubble-generating bathtub configured to be capable of spouting bathwater mixed with bubbles into the bathtub body, the air intake section is constituted by an in-bathroom air intake section and a bathroom-to-bathroom air intake section, and the air intake section is arranged between the air intake section and the bathtub body. A bubble-generating bathtub having a bath water temperature adjustment function is provided with an air switching valve between inside and outside the bathroom and a bubble ffi adjustment valve, and a drive motor for driving the adjustment valve is driven via an inverter. This is what we intend to provide.

(E) Function/Effect When the bather turns on the operation switch of the drive motor of the regulating valve that adjusts the amount of air bubbles, the drive motor is started by the action of the inverter having a frequency conversion function. The temperature of the air can be adjusted by controlling the rotation of the drive motor via an inverter to open and close the regulating valve, and at the same time switching the air switching valve in the air intake section.

Therefore, it is possible to adjust the amount of air bubbles in the bath water that is ejected from the ejection nozzle, and also to adjust the temperature drop caused by the air bubbles. This makes it possible to control the appropriate temperature according to the temperature.
