Description

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

(Explanation) Conventional technology The present invention provides a bath water circulation flow path consisting of a reiyu eye-filling flow path and a bath water forced flow path between a bathtub body and a circulation pump, and a bath water forced flow path. A plurality of ends of the flow path are opened in the bathtub body to serve as jetting nozzles, and an air intake part is connected to the bath water forced flow path to inject air bubbles into the bathtub body from the plurality of outlet nozzles. There is one in which the mixed bath water is selectively configured to emit water.

(c) Problems to be Solved by the Invention However, in the bubble-generating bath Tsubaki mentioned above, although bubble-mixed bath water can be selectively spewed out from a plurality of spouting nozzles and the spout location can be changed, When transitioning from the previous jet point to the next jet point, the jet flow at the previous jet point stops and then the jet flow at the next jet point starts, so the transition from the jet point to the next point is smooth. This may cause discomfort to bathers.

(2) Means for solving the problem Therefore, in the present invention, between the bathtub body and the circulation pump,
A bath water mfl flow path consisting of a bath water eye flow path and a bath thirst forced flow path is provided, and the end of the bath water forced flow path is inserted into the bathtub body.
One gate is opened to function as a spouting nozzle, and an air intake part is connected to the bathwater forced flow path, so that bath water mixed with air bubbles can be spouted into the bathtub body from multiple spouting nozzles. In the bubble generating bathtub, the amount of opening and closing of the plurality of jet nozzles described above can be controlled via the nil l part, and by opening and closing each jet nozzle, the jet flow location can be changed, and the jet flow location can be changed at the previous jet flow location. A bubble-generating bathtub in which the jet point can be changed is characterized in that the jet flow at the next jet point starts before the jet flow stops.
I would like to offer it to you.

Another feature is that the jet location can be changed periodically.

(e) Effects According to the present invention, the following effects are produced.

In other words, because the jet flow at the next jet point starts before the jet flow at the previous jet point stops, there is a certain overlap time during which hot water is spouted from both jet points, and the jet flow Smooth transition between areas and no discomfort to bathers! I won't have to worry about it anymore.

In addition, by periodically opening and closing several jet nozzles, the location of the jet can be changed periodically, which eliminates the problem of the bather's body becoming stimulated by the jet. To ensure an acupressure effect, etc., and prevent a bather from getting bored with bubble bathing.

Furthermore, even when the jet stream is made stronger, the jet stream changes periodically, so the jet stream does not hit the same part of the bather's body continuously, causing pain and discomfort to the bather. You can enjoy bubble bathing even for a long time without any problems.

After the elapsed time, the rotation speed (v0 (for example, 25
0Or. P. *) is gradually increased for a certain period of time 02)(
For example, a certain number of revolutions (V2) within 1 second (for example,
2800v. p. *), and the same rotation number (■2) is maintained during blowing operation.

In Fig. 8, the solid line (50〉) indicates the case where the mild blow is changed to the cycle blow, and the dotted line (51)
is from acupressure blow to cycle blow, and also from dotted line (
52) shows the case where pulse blowing is changed to cycle blowing, and the two-dot broken line <53> shows the case where wave blowing is changed to cycle blowing.

Further, in this embodiment, the cycle blow takes the form of acupressure blow, but is not limited to this, and may take other jet forms such as mild blow.

In addition, in this embodiment, the branch history of the jet flow part of the cycle pro was set to the sound side, ventral side, foot side → dorsal side, but it is not limited to this order, and other orders (for example, dorsal side It is also possible to make it one leg side, one ventral side → dorsal side).

Also, the jet location can be changed irregularly.

In this way, in this embodiment, when moving from the previous jet location to the next jet location, a certain overlap time 06) is provided so that bath water is spouted from both jet locations. The transition from one place to another can be performed smoothly, and the bather will not feel uncomfortable.

Moreover, in the cycle blow according to this embodiment, the jet location can be changed periodically by periodically opening and closing the 1d side dorsal and ventral jet nozzles (2), (3), and (4). Moreover, there is no problem that the bather's body becomes stimulated by the jet stream, the acupressure effect etc. of the jet stream is ensured, and the bather does not get tired of bubble bathing.

Furthermore, even when the jet stream is made stronger, the jet stream changes periodically, so the jet stream does not hit the same part of the bather's body continuously, causing pain and discomfort to the bather. You can enjoy bubble bathing even for a long time without any problems.
