BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bathtub capable of detecting the presence of a bath lid.

[0002]

2. Description of the Related Art Conventionally, in order to detect the presence of a bath lid covered on the upper surface of a bathtub, for example, a structure shown in a sectional view of a main part in FIG. 5 has been adopted. That is, in FIG. 5, a permanent magnet 52 is embedded in a bath lid 51, and a lead sensor 5 for detecting magnetic force is provided in a bathtub 53.
4 are provided. In such a conventional structure,
It is necessary to incorporate the permanent magnet 52 into the bath lid 51, and there is a problem that the design of the bath lid 51 is deteriorated and the cost is increased. There is a problem that it is necessary to make the permanent magnet 52 considerably large in consideration of the thickness of the magnet 53.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned conventional problems, and does not require the use of a dedicated bath lid, and provides a bathtub capable of detecting the presence of the bath lid satisfactorily. The gist of the invention is that a transmitter and a receiver for detecting the presence of a bath lid covered on the upper surface of the bath tub are respectively attached to a pair of grips installed opposite to each other on the inner wall of the bath tub.

[0004]

[Function] Since the transmitter and the receiver are attached to the grips provided opposite to the inner wall of the bathtub, the infrared light transmitted from the transmitter is reflected on the bath lid and received by the receiver, so that it is good. The state of the cover of the bath lid can be detected at the same time.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of a bathtub. A pair of grips 2 and 2 are installed in an upper portion inside the bathtub 1 so as to face each other. When the ultrasonic wave or the infrared ray is emitted upward from the transmitter 4 side, when the bath lid 8 is covered on the upper surface of the bathtub 1, the back surface of the bath lid 8 is attached. The infrared light and the like are reflected at, and the reflected light is received by the receiver 5. Note that the transmitter 4 and the receiver 5 are connected to lead wires 6, 6, respectively, and the respective lead wires 6, 6 are connected to an external control unit 9. For example, in an automatic cleaning bath,
The cleaning liquid is automatically spouted into the bathtub 1 via the control unit 9 to wash the inside of the bathtub 1.

The grip 2 has a structure as shown in a perspective view in FIG. 2. A handle portion 2a is formed at an upper portion of the grip 2 and protrudes inward at an angle, and is fixed to the inner wall of the bathtub 1. The fixing portion 2b is formed with two screw holes 2c, 2c. FIG. 3 is a front view of the grip 2, and FIG. 4 is a sectional configuration view of the grip 2 attached to the bathtub 1.

A screw 3 is inserted into each of the screw holes 2c, 2c, and the grip 2 can be fixed to the inner wall surface of the bathtub 1 via the screw 3. A transmitter 4 or a receiver 5 is mounted on the handle 2a of the grip 2. A mounting hole 2d that can be mounted is formed, and a tip of the mounting hole 2d has a window 7 into which a transparent plate or the like is fitted.
It has become. For example, the transmitter 4 can be mounted inside the window 7, and the lead wire 6 can be passed through the mounting hole 2d.

A through hole 1a is formed in the bathtub 1, the through hole 1a is aligned with the mounting hole 2d, and the lead wire 6 can be drawn out of the bathtub 1, so that electric wiring is easy. It will be. The grip 2 serves to support a hand or the like when taking a bath in or during bathing. Even if the transmitter 4 or the receiver 5 is attached, the design of the entire bathtub 1 is impaired at all. is not.

In this embodiment, since infrared rays and the like transmitted from the transmitter 4 are reflected on the back side of the bath lid 8 and received by the receiver 5, the bath lid 8 may be a commercially available bath lid. In addition, a low-cost bath cover can be used without having to be a dedicated bath cover. Further, since the reflection position of the infrared rays and the like transmitted from the transmitter 4 is in the air above the bathtub 1, no malfunction occurs even when a towel or the like is hung on the upper edge of the bathtub, and good operation is achieved. A detection state can be presented.

[0010]

[Effect of the Invention] The bathtub of the present invention has a transmitter and a receiver for detecting the presence of a bath lid covered on the upper surface of the bathtub, each of which is attached to a pair of grips installed oppositely on the inner wall of the bathtub. Utilizing the grip installed on the inner wall of the bathtub, the transmitter and the receiver can be incorporated into the grip well to form a bathtub with good design. The presence of a bath lid can be detected, and a commercially available bath lid can be used instead of a special one. Further, since the light is reflected on the bath lid and detected, there is an effect that there is no error movement and the bath lid can be accurately detected.
