Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a bubble jetting bath, and more specifically, to reliably drain residual water on the bubble jetting device side by a bubble producing device by operating an air pump. Technology.

[Prior Art] Conventionally, in a bubble jetting bathtub in which a plurality of fumarolic portions are arranged on the bottom surface of the bathtub and bubbles are jetted into the bathtub through the fumarolic portions, a pipe is arranged on the lower surface side of the bathtub. When the bubble generator is stopped, the hot and cold water in the bathtub flows into the pipe, and the hot and cold water remains in the pipe even when the drain plug of the bathtub is removed to drain the bathtub. However, if the air pipes are left with residual water for a long time in this way, scales may accumulate in the pipes, clogging the pipes, and discharging fumes from the fumes during reuse. However, there is a problem in that it is not sanitary, and that the amount of bubbles is reduced by promoting clogging of the fumarolic portion, impairing its mechanism. Therefore, in the bubble jetting device, it is necessary to drain the water in the pipe by some method after use. The simplest method is to remove the drain plug after use and then operate the air pump to eject the water in the pipe from the fumarolic portion into the bath by the discharged air for draining.

[Problems to be solved by the invention] However, it is easy to forget to operate the air pump after operating the air pump to drain residual water after finishing the bath, thus eliminating the problem of residual water. It was something I couldn't get.

The present invention has been made in view of such problems,
It is an object of the invention to provide a bubble jetting bath which can surely eliminate residual water in the pipe on the bubble generator side.

[Means for Solving the Problems] In the bubble jetting bathtub of the present invention, an air pump 18 connected to the jetting portion 2 is operated through a plurality of jetting portions 2 arranged on the bottom surface of the bathtub 1. Is a bubble jetting bathtub for jetting bubbles into the bathtub 1 by driving the bubble generator 24, and the opening of the drain plug 23 provided in the bathtub 1 is detected, and the air pump 18 is operated based on the detection result. It is characterized in that it is configured to operate for a fixed time.

[Operation] As described above, the opening of the drain plug 23 provided in the bathtub 1 is detected, and based on the detection result, the air bubble generator 24 is configured to be operated for a certain period of time by operating the air pump 18. By removing the plug 23, the bubble generating device 24 is automatically operated for a certain period of time, and the hot and cold water in the pipe 19 of the bubble generating device 24 side can be reliably eliminated, and the pipe of the bubble generating device 24 side can be kept for a long time. It is possible to maintain good quality over a long period of time and to perform good bubble ejection for a long period of time.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a bath apparatus, in which a bottom portion of the bath 1 is provided with a plurality of blowout portions 2 and an operation of an operation switch 17 drives an air pump 18 to drive a bubble generating device 24. Air is blown out through the pipe 19
The bubbles can be ejected into the bathtub 1 as bubbles.

As shown in FIG. 2, a drain plug 23 made of rubber is provided in the drain port 25 at the bottom of the bathtub 1 so that the drain plug 23 can be inserted and removed freely. The drain plug 23 is connected to a heaton plug 27 by a chain 26. Has been done. A switch (not shown) that is turned on by pulling the chain 26 is built in the drain plug 23, and a signal line 28 is drawn from the switch to the outside of the bathtub 1 along the chain 26 at the back of the heaton plug 27. This signal line 28
Is connected to the electric control circuit of the air pump 18.
In the electrical connection circuit, the air pump 18 is turned on for a certain period of time (bath 1
A control circuit is provided which operates for a certain period of time after all the hot water in the inside is drained.

Then, the opening of the drain plug 23 provided in the bathtub 1 is detected by the switch, the air pump 18 is operated for a certain period of time based on the detection result, and the drain plug 23 is pulled out in this way, thereby automatically generating the bubble generating device. 24 is operated for a certain period of time, the hot run of the air pump 18 is surely made to eliminate residual hot water in the pipe 19 of the bubble generating device 24 side, and the pipe of the bubble generating device 24 side is favorably maintained for a long period of time. . Then, after a certain period of time, the air pump 18 is automatically stopped.

FIG. 3 shows another embodiment, in which the pipe 19 from the air pump 18 is provided with a pressure switch 29, and when the drain plug 23 is pulled out, the water level in the bathtub 1 is lowered, and thus the pipe When the pressure change in 19 occurs and the pressure change reaches a certain level or more, the pressure switch 29 operates (turns on),
A control signal is input to the electric control circuit of the air pump 18 through the signal line 28, but the air pump 18 is operated for a certain period of time to drain the residual water in the pipe 19. In such a case, it goes without saying that the drain plug 23 does not include the switch shown in FIG.

FIG. 4 shows the structure of the fumarolic portion 2, in which the fumarolic portion main body 5 is inserted from above into the opening 3 formed in the bottom surface of the bathtub 1 and the nut 11 is screwed into the male screw portion 10 of the fumarolic portion main body 5. The peripheral portion of the opening 3 of the bath 1 is sandwiched between the nut 11 and the flange 12 of the body 5 of the fusible portion so that the body 5 of the fusible portion 1
It can be attached to. In such cases,
An O-ring 15 is arranged between the bathtub 1 and the main body 5 of the fume part above the peripheral part of the opening part 3, and a packing 13 is arranged on the lower surface of the peripheral part of the opening part 3 to ensure a reliable seal. Therefore, the hot water in the bathtub 1 is prevented from leaking. A foam body 7 is attached to the main body 5 of the fumarolic portion. The foam body 7 is a foam plate 9 made of a porous synthetic resin foam and a foam plate in which the foam plate 9 is fixed with an adhesive agent or the like with good sealing property. Case 1
4, the foam plate case 14 is screwed into the main body 5 of the gas ejection portion and is detachably attached.

As shown in FIG. 4, a taper 32 is formed on the inner surface of the foam plate case 14, and this taper 32 is a value that takes into consideration the residual volume indicated by diagonal lines and the uniform ejection of bubbles from the entire upper surface of the foam plate 9. It is set to (20 to 30 °). By forming the taper 32 on the inner surface of the foam plate case 14 in this manner, residual water in the pipe 19 and residual water in the foam plate case 14 can be effectively discharged by air.

As shown in FIG. 4, the foam plate 9 is formed flush with the foam plate case 14, and as shown in FIG. 1, the foam plates 9 are arranged on both sides of the bottom of the bath 1. It is designed so that the person does not feel a cold sensation by directly touching the buttocks and the foaming is not hindered. Even with such a configuration, when the residual water is drained, the water drained on the upper surface of the foam plate 9 is smoothly drained into the bathtub 1 along the upper surface of the fumarolic unit body 5.

[Effects of the Invention] In short, the present invention is configured to detect the opening of the drain plug provided in the bathtub and, based on the detection result, drive the bubble generator for a certain period of time by operating the air pump. By removing the drain plug, the bubble generator can be automatically operated for a certain period of time, the hot and cold water in the bubble generator pipe can be reliably eliminated, and the bubble generator pipe can be kept for a long time. There is an advantage that it can be maintained satisfactorily and bubble ejection can be performed satisfactorily for a long period of time.
