Description

[Detailed explanation of the idea] This invention relates to an in-bath bubble generator.

BACKGROUND ART A bath bubble generating device is known that generates bubbles in a bathtub to give appropriate stimulation to the skin during bathing, and also has a pine surge effect that promotes blood circulation, a heating effect, and a cleaning effect.

Generally, this in-bath bubble generation device is composed of a compressor serving as a supply source of compressed air, and a foam body connected to the compressor by an air guide hose.

The compressor is equipped with an electrical system, and if it gets wet with water, it is likely to malfunction or cause an electric shock accident due to electrical leakage.

Therefore, normally a compressor is placed outside the bathroom, and an air-conducting hose is led into the bathroom to supply compressed air to the foam placed at the bottom of the bathtub. Since it is connected to the body through a single air conduction hose, during use, a gap approximately the same size as the outside diameter of the air conduction hose will be created at the entrance to the bathroom or at the window. There was an inconvenience that wind could enter the bathroom through the gap, possibly causing hot water leaks.

Additionally, if the power outlet is located far from the entrance of the bathroom, the bather will have to go to where the compressor is located to temporarily stop foaming.
In this case, it was extremely dangerous to operate the compressor while wet.

Due to these inconveniences, foaming was interrupted by taking the foam out of the bathtub instead of turning it off each time, but since the compressor was still running, electricity was wasted. This was not desirable from the standpoint of power saving.

In view of the above-mentioned disadvantages of conventional bath bubble generators, this idea was developed to allow bathers to use the compressor's power supply while in the bathroom while using the bath bubble generator. It was devised to prevent electrical shocks caused by current leakage and drafts from entering the bathroom, as well as to save power.

An embodiment of this invention will be described below with reference to the accompanying drawings.

Fig. 1 shows the state of use, in which compressed air brought by a compressor 1 is supplied to a foam 3 submerged in a bathtub through an air guide hose 2. The hose 2 is divided into two parts: an air guide hose 2 a connected to the compressed air outlet of the compressor 1 and an air guide hose 2 b connected to the compressed air intake of the foam 3 .

Note that the lengths of the air guide hoses 2a and 2b are not specified, but if the distance from the door 41 to the bottom of the bathtub 7 is shorter than the distance from the compressor 1 to the door 41, then the length of the air guide hoses 2b is shorter than the length of the air guide hose 2a.

The end of the air guide hose 2a connected to the compressed air outlet of the compressor 1 is provided with a female fitting 10 in the form of a valve body. A male joint body 11 that pairs with the female body 10 is provided at the end of the air hose 2b.

3 and 4 show a joint consisting of a female body 10 and a male body 11. The female body 10 is elastically repelled by a compression spring 12, and when separated from the male body 11, a valve body 13 closes the flow path. Built-in.

Reference numeral 14 denotes a backing that comes into contact with the valve body 13 to seal the flow path.

When the male body 11 is inserted into the female body 10, the male body 11 comes into contact with the gasket 14 to form a fluid-tight seal, and the valve body 13 is moved against the elastic force of the compression spring 12 to open the female body 10.11. The channels are opened to each other.

A ball 1 for locking the female body 10 is provided in the outer peripheral groove 15 of the male body 11.
6 is locked, and the operation ring 17 maintains this connected state.

When the operating ring 17 is withdrawn against the elastic force of the compression spring 18, the ball 16 is released from the locking restraining force of the operating ring 17, so that the female body 10 and the male body 11 can be separated.

Reference numeral 19 is a cock for adjusting the flow rate provided in the female body 10, and the scale 20 is useful for displaying the amount of air introduced by turning the cock 19. Therefore, when the cock 19 is turned, the amount of air bubbles can be adjusted. can do.

The compressor 1 placed outside the bathroom has an automatic pressure switch (not shown) built-in.

When the coupling female and male bodies 10.11 are in the separated state, the valve body 13 built into the female body 10 is automatically closed, as described above.

If the compressor 1 continues to operate, the pressure of the compressed air produced by the compressor will normally continue to rise, but when this pressure rise reaches a certain point and reaches a predetermined value, the pressure increases in response to this. The switch works automatically to turn off the power to compressor 1.

As a result, the power supply to the compressor 1 is cut off, and the compressor 1 automatically stops operating.

Therefore, when washing the body, if the male and female bodies 10.11 are separated and the air guide hose 2a connected to the compressor 1 is taken out of the bathroom, the door 41 can be opened as shown in FIG. can be completely closed off, preventing drafts from entering the bathroom.

Also, when the male and female bodies 10.11 are separated, as mentioned above,
Since the compressor 1 automatically stops operating, there is no need to go to the place where the compressor 1 is located and turn it off every time you want to stop the compressor, which is convenient and also helps save electricity.

Reference numeral 30 denotes a thin or flat connecting device of a required length that connects the female body 10 and the male body 11, and when the female body 10 and the male body 11 are separated, this connecting device 30 is sandwiched between the doors 41. When attempting to connect the female body 10 and the male body 11 again, by pulling together the air guide hose 2b on the bathroom side, the other air guide hose 2a can be guided into the bathroom without leaving the room.

Note that the communication device 30 shown in FIG. 5 is made of a synthetic resin ribbon 31.
A T-shaped portion 32 extends at both ends of the gap, and a pair of extraction holes 33 and a headed projection 34 are individually arranged at both ends of the intervening portion 32, and the headed projection 34 is inserted into the extraction hole 33 and locked. A ring 35 which is fitted onto the female body 10 and the male body 11 is formed by this.

In addition, you can use any chain, braid, or other material with the thickness, thickness, and width that will allow you to close the door 41. You should choose the one that doesn't exist.

Although the embodiments have been described above, this invention is based on an air bubble that connects a compressor installed outside the bathroom and a foam submerged in the bathtub with an air conduction hose through a removable joint consisting of a male and female joint. The generator is provided with a joint on the compressor side that has a valve that has the function of automatically closing the flow path when it dissociates and the function of increasing or decreasing the amount of air supplied to the foam, and A joint is provided on the foam side to push open the valve when connected, and the compressor detects the pressure in the discharge flow path, and when the pressure reaches a predetermined value, the compressor opens the valve on the electric drive source side of the compressor. Since it has a built-in automatic pressure switch configured to cut off the electrical circuit, during bathing, you can adjust the amount of air passing through the foam by operating a valve in your hand. , it is possible to generate air bubbles of the strength you like in the bath, and when you are washing your body in the washing area, the air supply from the compressor is shut off with a valve that automatically closes when they dissociate. When the pressure reaches a predetermined value, the pressure switch automatically stops the compressor, stopping unnecessary operation of the compressor and saving power.

Therefore, according to this invention, there is no need to operate the power supply of the compressor to adjust the air volume or start/stop the compressor during bathing, and the amount of air bubbles discharged in the bathroom can be controlled without touching the electrical system at all. It is extremely safe and can be used to stop air bubbles from being emitted.
