Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure of an air pipe in a bubble bath provided with a bubble generator.

[Prior Art] Conventionally, a bathtub equipped with a bubble generator is known. That is, the bubble generating device sucks the hot and cold water of the bathtub 1 from the hot and cold water suction port 8 through the pipe 9 by the action of the pump 10, further pressure-feeds it to the bubble nozzle 2 through the pipe 9 and ejects it from the bubble nozzle 2 to the bathtub 1. At this time, air is sucked into the bubble nozzle 2 from the air pipe 3 by the ejector action, and hot water is jetted from the bubble nozzle 2 in a state where the air is mixed as bubbles to generate bubbles in the bathtub 1. It was As shown in FIG. 3, the air pipe 3 floats on the water surface of the bathtub 1 at the tip of the air pipe 3 and collects dust on the water surface in the bathtub 1 when a negative pressure is generated in the air pipe 3. A dust removing device 4 is provided to remove dust from the air pipe 3.
A filter 5 for accumulating the collected dust and a branch pipe 7 connected to an air suction port 6 capable of opening and closing the suction of air were provided between the air bubble nozzle 2 and the bubble nozzle 2. Therefore, when the air suction port 6 is opened, air is sucked from the air suction port 6 and hot water mixed with the air is ejected from the bubble nozzle 2, and when the air suction port 6 is closed, dust is generated. Hot water is sucked together with dirt from the take-up device 4, dirt is collected by the filter 5, and hot water is ejected from the bubble nozzle 2.

[Problems to be Solved by the Invention] In the conventional example, since the height of the air pipe 3 is low, even if the water level of the bathtub 1 is high, even if the air suction port 6 is fully opened, the dust removing device 4 can be opened. The amount of bubbles from the bubble nozzle 2 was reduced because the hot and cold water in the bathtub 1 was sucked in. When the air pipe 3 is slightly higher than the water level in the bathtub 1, when the air suction port 6 is fully closed, the hot water is sucked from the dust removing device 4 to the bubble nozzle 2 side by a negative pressure. Even if the air suction port 6 is opened while the power is on, the force of sucking hot water from the dust removing device 4 side when sucking by the ejector action resists the resistance when sucking air into the air pipe 3 from the air suction port 6. There was a situation in which hot air and water were still sucked into the bubble nozzle 2 from the air pipe 3 connected to the descaling device 4, and the required air could not be sucked in, since the force was larger than the force for sucking air.

The present invention was devised in view of the above-mentioned conventional problems, and its purpose is to remove the hot and cold water in the bathtub from the air pipe connected to the descaling device 4 when trying to suck air. (EN) It is an object to provide a structure of an air pipe for a bubble bath which does not suck in and does not reduce the amount of bubbles.

[Means for Solving the Problems] The structure of the air pipe of the bubble bath according to the present invention is an air pipe for supplying air to a bubble nozzle 2 for ejecting hot water containing air bubbles into the bath 1 by an ejector action. 3 is connected, and a descaling device 4 is provided at the tip of the air pipe 3 to collect dust on the water surface in the bath 1 when floating on the water surface of the bath 1 and a negative pressure is generated in the air pipe 3. A filter 5 for collecting the dust collected between the dust removing device of the pipe 3 and the bubble nozzle 2.
And a branch pipe 7 connected to the air suction port 6 capable of opening and closing the suction of air and a part of the air pipe 3 between the dust removing device 4 and the branch pipe 7 connected to the air suction port 6
The level is almost equal to that of the upper edge, and by adopting such a configuration, the above-mentioned object of the present invention is achieved.

[Operation] That is, in the present invention, a part of the air pipe 3 between the dust removing device 4 and the branch pipe 7 connected to the air suction port 6 is at a level substantially equal to the upper edge of the bathtub 1. Therefore, when the air suction port 6 is closed, hot water is sucked from the dust removing device 4 to collect the dust, and when the air suction port 6 is opened, even if the water level becomes high, the dust removing device 4 From No. 4, it is possible to suck only air from the air suction port without sucking hot and cold water into the air pipe.

[Embodiment] The present invention will be described in detail below based on an embodiment shown in the accompanying drawings.

A bubble nozzle 2 and a hot and cold water inlet 8 are provided on the side wall of the bathtub 1, and the bubble nozzle 2 and the hot and cold water inlet 8 are connected by a pipe 9. A pump 10 is provided between the hot and cold water suction port 8 of the pipe 9 and the bubble nozzle 2. The bubble nozzle 2 is connected to an air pipe 3 for supplying air to the bubble nozzle 2 which ejects hot and cold water containing bubbles mixed into the bath 1 by an ejector action. A decontamination device 4 is provided at the tip of the air pipe 3 to collect dust on the water surface in the bath 1 when it floats on the water surface of the bath 1 and a negative pressure is generated in the air pipe 3. The descaling device 4 is arranged in the bathtub 1 and is fixed in the fixed tube 1.
A movable cylinder 12 which can move up and down is fitted on the upper part of 1. The movable tube 12 itself is formed of a material that floats in water, or the movable tube 12 is provided with a float (not shown), and the upper end opening of the movable tube 12 is substantially the same as the water surface of the bathtub 1. It is floating on the water to reach the level. Between the dust removing device 4 of the air pipe 3 and the bubble nozzle 2, a filter 5 for storing the collected dust and a branch pipe 7 connected to an air suction port 6 capable of opening and closing the suction of air
And are provided. Here, the air suction port 6 is located above the upper edge of the bathtub 1, and is attached to the upper surface side of the flange 13 at the upper edge of the bathtub 1 in the embodiment of the accompanying drawings.
The air suction port 6 is opened and closed by operating the operation portion 14 such as a knob. Air pipe 3 between the dust removing device 4 and the branch pipe 7 connected to the air suction port 6
There is a part of the level almost equal to the upper edge of bathtub 1,
It is the header portion 3a. Here, in order to bring a part of the air pipe 3 to a level almost equal to that of the upper edge of the bathtub 1, for example, one shown in FIG. 1 or 2 is used.

Then, when the pump 10 is operated, the hot water suction port 8 is pressure-fed to the bubble nozzle 2 through the pipe 9 and jetted into the bathtub 1. In this case, when the air suction port 6 is closed, the ejector is closed. By the action, the air sucked from the air suction port 6 is sucked into the bubble nozzle 2 and mixed with the hot and cold water, and the hot and cold water is jetted into the bathtub 1 in a state where the air is mixed as the bubbles. Bubbles can be generated. The jetted bubbles act on the body together with the jet to exert a massage effect, and when the hot and cold water in the bathtub 1 flows, the sensible temperature becomes about 1 to 3 ° C higher than it actually is, and after bathing. It has the effect that there is little decrease in body temperature and it is difficult to cool with hot water.

On the other hand, when the air suction port 6 is opened, a negative pressure is generated in the air pipe 3, and dust on the water surface in the bathtub 1 is collected by the dust removing device 4, and the dust is collected by the filter 5. The hot and cold water sucked together with the dirt is sucked into the bubble nozzle 2 and ejected from the bubble nozzle 2 into the bath 1. In this way, dirt floating on the water surface of the bathtub 1 can be collected.

By the way, if the air pipe 3 is slightly higher than the water level in the bathtub 1, the hot water is sucked from the dust removing device 4 to the bubble nozzle side by a negative pressure when the air suction port 6 is fully closed. Even if the air suction port 6 is opened while 10 is operating, the force of sucking hot water from the air pipe 3 connected to the dust removing device 4 at the time of sucking by the ejector action sucks air into the air pipe 3 from the air suction port 6. The air bubble nozzle 2 is larger than the force that tries to draw in air against the resistance of time.
In addition, a situation occurs in which hot and cold water is still sucked in from the descaling device 4 side and necessary air cannot be sucked in.
On the other hand, in the present invention, a part of the air pipe 3 between the dust removing device 4 and the branch pipe 7 connected to the air suction port 6 is at a level substantially equal to the upper edge of the bath 1. Even if the water level in the bathtub 1 rises, a part of the air pipe 3 can be positioned relatively higher than the water level in the bathtub 1. As a result, the air suction port 6 is closed and the pump 10 is operated. Since the height from the water level to a part of the air pipe 3 is high even if the air suction port 6 is fully opened in the state where the hot water is sucked from the dust removing device 4, the height of the dust removing device 4 to the bathtub 1 is increased.
The air can be reliably sucked from the air suction port 6 without sucking the hot water inside.

[Effect of the Invention] In the present invention, as described above, a part of the air pipe between the dust removing device and the branch pipe connected to the air suction port is at a level almost equal to the upper edge of the bath. , When the air suction port is opened, hot water is sucked from the descaling device to collect the debris, and when the air suction port is closed, hot water is removed from the descaling device even if the water level becomes high. Only air can be sucked from the air suction port without sucking, and as a result, the amount of bubbles is not reduced. 4.
