Abstract

PURPOSE:To prevent trouble such that the body of a bathing person becomes habituated to the stimulation due to the jet stream in a definite direction by separately opening and closing a plurality of jet nozzles cyclically to change jet stream places cyclically and changing the number of rotations of a recirculation pump cyclically. CONSTITUTION:The opening and closing of jet nozzles 2, 3, 4 on foot, back and abdomen sides automatically variable in jet quantity and the number of rotations of the recirculation pump P are made controllable by a control part C and the respective jet nozzles 2, 3, 4 are cyclically opened and closed to cyclically change jet stream places and the number of rotations of the recirculation pump P is cyclically changed to make it possible to impart a jet stream of a moving wave image to a bathing person from the jet stream places altered cyclically. Especially, the number of rotations of the recirculation pump P is controlled by an inverter to make it possible to smoothly perform the alteration of jet stream intensity. Further, by changing the opening quantities of the jet nozzles 2, 3, 4 subjected to opening operation, jet streams alternately changing in mildness and an acupressure feeling can be given to the bathing person from the cyclically altered jet stream places.

Description

[Detailed description of the invention]

(a) Industrial Application Field The present invention relates to a bubble-generating bathtub that controls the location of jet flow. (b) Conventional technology Conventionally, as a basic form of a bubble-generating bathtub, Japanese Patent Application Laid-Open No. 59-1
As described in Publication No. 35058, a bath water circulation flow path consisting of a bath water suction vibrator and a bath water bullet delivery pipe is interposed between the bathtub body and a circulation pump installed outside the bathtub body. However, there are some types of bathtub vibrators that have an air intake part in the middle. With this configuration, the circulation pump sucks the bath water inside the bathtub body through the bath water suction vibrator, and the circulation pump causes the bath water to pass through the bath water delivery pipe and squirt it into the bathtub body from the discharge part of the pipe. At this time, the air intake is mixed with the air taken in by using the negative pressure caused by the hot water jetting out from the air intake part, so that the hot water mixed with bubbles can be jetted out. ing. In addition, the bubble-generating bathtub having the above-mentioned basic configuration is equipped with a control valve that adjusts the amount of air intake in the middle part of the air intake pipe connected to the air intake section, and the control valve adjusts the amount of air intake. By adjusting the jet pressure of the bubble-mixed bath water, you can enjoy a jet stream with a desired jet pressure. In addition, Japanese Patent Application Laid-open No. 1983-H61 discloses that fine bubbles and normal bubbles having a larger diameter than the same fine bubbles can be ejected together with bath water selectively or in combination with the bath water. A bubble-generating bathtub that allows even the sick and sick to take a bath is described. (c) Problems to be Solved by the Invention However, the bubble-generating bathtub described in JP-A-59-135058 can only change the ejection pressure of bath water by adjusting the amount of intake air; Japanese Patent Publication No. 1983-3
The bubble-generating bathtub described in Japanese Patent No. 881 can only select the state in which fine bubbles and normal bubbles are ejected. In this way, both of them only take the form of a simple jet flow of bath water, and because the jet flow location cannot be changed periodically, the body of the bather is affected by the jet flow from a fixed direction. There was a problem that the acupressure effect of the jet stream was reduced due to the stimulation. (d) Means for Solving the Problems Therefore, in the present invention, a bath consisting of a bath water suction flow path and a bath water bomb delivery flow path is provided between a bathtub body and a circulation pump installed outside the bathtub body. A hot water circulation flow path is provided, and the ends of the bath water bullet feed flow path are opened at multiple locations within the bathtub body to form multiple spout nozzles, and an air intake portion is communicated with the hot water forced flow flow path. In the bubble-generating bathtub, which is configured such that the spouting nozzles are connected to each other so that bath water mixed with bubbles can be spouted into the bathtub body, the opening and closing of the spouting nozzles and the rotation speed of the circulation pump are controlled via a control unit. The invention is characterized in that the plurality of jet nozzles are periodically and independently opened and closed, thereby periodically changing the jet flow location and periodically changing the rotation speed of the circulation pump. It is an object of the present invention to provide a bubble generating bathtub that controls the location of jet flow. Another feature is that each jet nozzle is periodically opened and closed to periodically change the jet flow location, and the opening amount of the jet nozzle that is being opened is also periodically changed. (e) Effects According to the present invention, the following effects are produced. ■Because the control unit can periodically open and close each jet nozzle to change the location of the jet flow periodically, the body of the bather becomes stimulated by the jet flow from a fixed direction. In addition to being able to prevent problems, it is also possible to enjoy changes in the jet flow location. ■By periodically changing the rotation speed of the circulation pump, the strength of the jet flow can be varied, and the periodically changing jet points give a jet that resembles waves that return to the bather. I can do it. Therefore, the bather can enjoy the synergistic effect of the above effect (1) and the jet effect, which gives the bather the image of waves approaching and returning. ■ By periodically changing the opening amount of the jet nozzle, it is possible to create periodic changes in the jet amount and jet pressure of the bath water, and the periodically changing jet flow points give the bather a mild and shiatsu sensation. Alternating jets can be provided. Therefore, the bather can enjoy the synergistic effect of the above effect (1) and the jet effect that gives the bather an alternating sensation of mildness and acupressure sensation. Here, the above-mentioned period is not limited to a constant period but also includes a variable period.

In case of bathing, there is a function to change the strength level of the hot water
It is possible to operate. Regarding the operation of changing the spout position and strength level of the bath water

Refer to and explain. [Timer operation] Timer operation allows the bather to set the desired blow operation time.
It is possible to set the temperature to prevent hot flashes caused by long baths.
The operation of the timer operation is explained below.

The timer operation starts, and the one-hour display on the timer starts.
The value decreases every second (595). Also, press the timer switch (114) while the timer is running.
Without pressing the button to turn it on (60ON), the timer is turned on.
The time has passed and the timer 1 hour display reaches ro:oo.
(605), the time taken will be displayed for 0.5 seconds.
It flashes for 5 seconds every time and sounds a buzzer.
After that, the timer operation ends (610) and the operation stop message is displayed.
At the same time, the timer returns to one hour display (615)
. Also, set the timer one hour to a time other than the five minutes mentioned above.
If you want to set the time, press the timer switch (114) for 2 seconds.
If you keep pressing it (59ON), the above "5" will change to 0.

I'm trying to stop it. In this way, blowing operation can be stopped after a certain period of time.
Due to this, the bather forgets to stop the blow operation.
This prevents the problem of continuous blowing operation for a long time.
