Description

[Detailed Description of the Invention] The present invention relates to a bathtub equipped with an electric switch.

The bathroom is an inappropriate place to install an electric switch because of its high humidity and the possibility of getting wet. If an electric switch is needed to notify or contact people outside, it is installed in a location outside the bathroom near the entrance. Naturally, this had the problem that it could not be operated from within the bathroom, making it quite inconvenient to use.

The present invention was developed with the aim of solving these conventional problems, and includes a reed switch that is embedded inside the switch body and subjected to moisture-proof treatment, and a corresponding reed switch on the surface of the switch body. By installing an electric switch consisting of a permanent magnet attached to the operating knob on the flange of the bathtub, we have created a bathtub where there is no risk of electric shock and the electric switch can be operated not only in the bathroom but also while in the bathtub. This is what was provided. below,
The illustrated embodiment will be described.

In FIG. 1, reference numeral 1 denotes a bathtub body having a flange 2 and an apron 3, and an electric switch 4 is provided at the corner of the flange 2. electric switch 4
As shown in FIG. 2, the switch body 5 is installed from above into a mounting hole (not shown) provided in the flange 2 through a rubber seal 6, and is fixed with a tightening nut 7. An operating knob 8 is pivoted on the surface. 9 is a lead wire. Here, as shown in FIG. 2, the electric switch 4 is attached to the flange 2 of the bathtub body 1, and the operating knob 8 is located on the upper surface side of the flange 2. FIG. 3 shows the structure of the electric switch 4. The switch body 5 consists of a plate part 5a and a threaded part 5b. A reed switch 10 is arranged at a position off center on the plate part 5a, and a lead wire is connected to the switch body 5. After connecting 9, a synthetic resin 11 is filled. Further, a permanent magnet 12 is attached to the operation knob 8 provided on the switch body 5 at a position offset from the center of the back surface corresponding to the reed switch 10.

When the operating knob 8 is rotated here, the distance of the permanent magnet 12 to the reed switch 10 changes, and the reed switch 10 is turned on when the permanent magnet 12 is closest to it and turned off when the permanent magnet 12 is far away. By operating the operating knob 8, the reed switch 10 can be opened and closed. A plurality of reed switches 10 can be provided depending on the application, and a plurality of permanent magnets 12 can also be provided, and one or more required reed switches 10 can be selected at the same time to open and close depending on the rotation angle of the operating knob 8. You can also do it like this.

The electrical switch 4 constructed in this way and the control box 13 installed outside the bathroom as shown in FIG.
are connected by lead wires 9, and the required controlled equipment is operated. Furthermore, if low-voltage electricity of, for example, 6V is supplied to the electric switch 4 from the control box 13 via an isolation transformer, there is no risk of electric shock since the electric switch 4 itself has a structure that does not expose live parts. It can be a safe switch.

FIG. 5 shows an example in which the bathtub of the present invention is used for a bubble bath, in which a pump 16 is installed between the suction port 14 and the injection port 15 provided on the side wall 1a of the bathtub body 1.
Electric switch 4 and pump 16 provided on flange 2
and lead wire 9, control box 13, lead wire 1
7 and the pump 16 is turned on by the electric switch 4.
It is designed to operate. When the pump 16 is operated, hot water is sucked in from the suction port 14, and when hot water is injected from the injection port 15, the air sucked in from the air pipe 18 is drawn in by the injection port 15 and countless air bubbles are ejected. It is also possible to drive the compressor to inject only air bubbles.

In addition, although the above-mentioned embodiment shows the case where the operating knob is of a rotary type, the operating knob may be of other types such as a sliding type.

As mentioned above, the present invention consists of a reed switch that is embedded inside the switch body and subjected to moisture-proof treatment, and a control knob attached to the surface of the switch body. An electric switch consisting of a permanent magnet that turns on the reed switch and turns it off when removed from the bathtub body is installed on the flange of the bathtub body, and the operating knob of the electric switch is located on the top side of the flange. You can control electrical devices such as bubble baths or reheating devices not only in the bathroom, but even while in the bathtub by reaching out and operating the electric switch, so you can easily control electrical devices such as bubble baths or reheating devices by reaching out and operating the electric switch, so you can easily control electrical devices such as bubble baths or reheating devices by reaching out and operating the electric switch even when you are in the bathtub. can be controlled to emit bubbles, and even
It can be used to reheat the hot water, and even when used as a so-called nurse call, the electric switch operation knob is located on the top side of the flange, so the bather can use the electric switch to call while taking a bath. When operating the device, the control knob can be easily operated by slightly moving the hand placed on the top surface of the flange without having to get up, making it extremely easy to operate.As a result, operability can be greatly improved. It is convenient and can be configured so that the live part is not exposed, so it can be used safely even in humid places without problems such as electric shock.The structure of the switch part is simple, so there is no failure, and the electric switch can be easily used. It has the advantage of being easy to install in a bathtub.
