Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to a technology for draining water in the air piping of the air ejection device in a bathtub equipped with an air ejection device that ejects air into the bathtub.

[Background Art] Bathtubs that generate air bubbles by jetting air into the bathtub have been known. However, in the past, the air blowing device was independent from the bathtub, and when taking a bath, the air generating device was brought into the bathtub and used. This is mainly because it is difficult to drain and clean the air piping of the air jetting device, so the air jetting device is made independent from the bathtub, and after use, the air jetting device is taken out from the bathtub to drain water or to be cleaned.

However, from the viewpoint of ease of use, it is preferable to attach the air blowing device integrally to the bathtub.
However, when an air blowing device is attached to a bathtub, the water in the air piping of the air blowing device cannot be drained, so water accumulates in this area, causing various negative effects such as becoming unclean and freezing. There was a problem.

[Purpose of the invention] The present invention was devised in view of the above points, and its purpose is to drain water from the air piping in a bathtub with an air jet device attached to the bathtub, and to facilitate cleaning. To provide a bathtub with an air jetting device which can prevent freezing troubles and can drain water from air piping of the air jetting device with a simple configuration.

[Disclosure of the invention] The bathtub with an air jetting device of the present invention includes an air jetting device for jetting air into the bathtub 1 attached to the bathtub 1, and a drainage pipe 4 in the middle of the air piping 3 of the air jetting device 2. Connect one end, connect the other end of the drain pipe 4 to the drain 5 of the bathtub 1,
The other end of the drain pipe 4 can be closed off by a drain plug 6 that allows the drain port 5 to be opened and closed, and by adopting such a configuration, the above-mentioned object of the present invention has been achieved. . That is, in the present invention, the water in the air piping 3 can be drained by providing the drainage pipe 4 in the middle of the air piping 3, and the other end of the drainage pipe 4 can be connected to the bathtub 1.
The other end of the drain pipe 4 can be closed by a drain plug 6 connected to the drain port 5 of the bathtub 1, and the drain port 5 can be opened and closed freely. Opening and closing of drain port 5 of 1 and drain pipe 4
can be opened and closed at the same time, and the water in the air pipe 3 can be drained with a simple configuration.

The present invention will be explained in detail below with reference to Examples. A recess 7 is provided in the bottom of the bathtub 1, and a blow disk 9 of an air blowing device 2 is disposed in the recess 7. The air pipe 3 is connected to the recess 7, the other end of the air pipe 3 is connected to the pump 8, and these recesses 7
An air blowing device 2 is composed of a blower disk 9, an air pipe 3, and a pump 8 inside. One end of a drainage pipe 4 is connected to the lowest part of the air piping 3 of the air blowing device 2. Here, one end of the drain pipe 4 is opened in the same direction as the flow direction of the air at the connection part of the air pipe 3, and in the embodiment shown in the drawings, one end of the drain pipe 4 is led out into the air pipe 3. This lead-out portion 10 is made to protrude in the direction of air flow, and by doing so, the tip opening of the lead-out portion 10 is opened in the direction of air flow.

The other end of the drain pipe 4 is connected to the side wall of the drain port 5 of the bathtub 1. A drain plug 6 is fitted into the drain port 5 so that it can be opened and closed freely.
When inserted into the drain pipe 4 on the side of the drain plug 6
The other end is closed.

However, when using the pump switch 1
1 to generate air from the pump 8, which passes through the air pipe 3 and generates bubbles from the blower plate 9 in the bathtub 1. On the other hand, when draining water, when the drain plug 6 is removed, the hot water in the bathtub 1 is drained from the drain port 5, and at the same time the other end of the drain pipe 4 is opened. Water is drained from 4 to drain port 5. Note that if one end of the drain pipe 4 is opened in the same direction as the air flow direction at the connection part of the air pipe 3 as in the embodiment shown in the drawings, even if high-pressure air flows inside the air pipe 3, the water will not drain. This prevents air from leaking from the drain plug 6 side due to negative pressure inside the pipe 4. In the above embodiment, the blower disk 9 is arranged at the bottom of the bathtub 1, but the blower disk 9 may be arranged inside the bathtub 1. In this case, a recess may be provided inside the bathtub 1, and the blower plate 9 may be placed in this recess.

[Effect of the invention] In the present invention, as described above, an air blowing device for blowing air into the bathtub is attached to the bathtub, and one end of the drain pipe is inserted in the middle of the air piping of this air blowing device. Even though the air blowing device is attached to the bathtub, the water in the air piping can be drained away through the drain pipe, and water does not accumulate in the air piping, making it sanitary. Moreover, since water does not accumulate in the air piping, it is possible to prevent water from freezing in the air piping and causing various troubles. Moreover, the other end of the drain pipe is connected to the bathtub's drain port, and the other end of the drain pipe can be closed by a drain plug that allows the drain port to be opened and closed. You can open and close the bathtub drain and the drain pipe at the same time.
Water in air piping can be drained with a simple configuration.
