Various noises such as a shower sound are generated in a bathroom. In particular, in the case of a so-called jet bath in which a large amount of foam is jetted into a bathtub, the noise level is relatively large and is constantly generated.

[0004] Therefore, the conventional bathroom apparatus has a problem that when the user is in the bathtub, the user may be worried about the noise and cannot relax sufficiently.

[0005]

DISCLOSURE OF THE INVENTION The present invention has been proposed in view of the above points, and it is possible to reduce noise entering a user's ear when the user positions his / her head near a headrest of a bathtub. Its purpose is to provide a device.

In order to solve the above problems, the present invention provides:
The following technical measures have been taken:

According to a first aspect of the present invention, there is provided a bathroom device provided with a noise removing device for removing noise near a headrest of a bathtub.

[0008] According to a preferred embodiment, the noise elimination device includes a microphone arranged near the headrest,
A speaker, a phase inversion circuit for inverting the phase of the output signal of the microphone, and a level of the output signal of the phase inversion circuit controlled in accordance with the level of the output signal of the microphone, and the signal is supplied to the speaker as a drive signal for driving the speaker. And a level adjusting circuit for supplying.

According to another preferred embodiment, the speaker and the microphone are respectively provided on both sides of the headrest of the bathtub.

[0010] According to another preferred embodiment, the loudspeaker is located near the headrest of the bathtub and farther from the headrest than the microphone.

According to another preferred embodiment, the speaker and the microphone are embedded in a bathtub.

According to the present invention, since the noise eliminator for removing noise near the headrest of the bathtub is provided, the user can place the head near the headrest of the bathtub, that is, put the head on the headrest of the bathtub. You can relax and enjoy bathing without the noise when the part is placed or the head is located near the headrest with your back along the inner wall of the bathtub.

[0013] Other features and advantages of the present invention will become more apparent from the detailed description given below with reference to the accompanying drawings.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be specifically described below with reference to the drawings.

FIG. 1 is a schematic plan view of a main part of a bathroom device according to the present invention. FIG. 2 is a schematic vertical sectional front view. At the upper edge of the bathtub 1, the headrest 2 is recessed. Near the headrest 2 of the bathtub 1, a pair of speakers 3 a and 3 b are embedded in the bathtub 1 with the headrest 2 interposed therebetween. Microphones 4a and 4b are embedded in bathtub 1 between speakers 3a and 3b and headrest 2. On the side wall 5 of the bathroom located near the end opposite to the headrest 2 of the bathtub 1, a bath remote controller 6 for remotely controlling a hot water supply device for supplying hot water to the bathtub 1 is installed.

FIG. 3 is a circuit block diagram of a noise elimination device provided in a bathroom device according to the present invention. FIG. 3 shows only the circuit of the right channel, but the circuit of the left channel has the same configuration. The noise elimination device is a speaker 3
a and a microphone 4a, a phase inversion circuit 11 and a level adjustment circuit 12 are provided. The level adjustment circuit 12 includes a level detection circuit 13 and a gain control circuit 14. This noise elimination device has a bath remote controller 6 except for a speaker 3a and a microphone 4a.
It is built in.

The phase inversion circuit 11 inverts the phase of the output signal of the microphone 4a.

The level adjustment circuit 12 includes a microphone 4a
The level of the output signal of the phase inverting circuit 11 is controlled in accordance with the level of the output signal of the above, and the signal is supplied to the speaker 3a as a drive signal.

The level detection circuit 13 includes a microphone 4a
And outputs a detection signal corresponding to the detected level.

The gain control circuit 14 is responsive to the detection signal from the level detection circuit 13 to
Control the level of the signal from

Next, the operation will be described. Noise near the headrest 2 is input to the microphone 4a. A signal corresponding to this noise is sent from the microphone 4a to the phase inversion circuit 1
1 and the level detection circuit 13.

The signal output from the microphone 4a is phase-inverted by the phase inversion circuit 11, and the level is detected by the level detection circuit 13.

The signal whose phase has been inverted by the phase inverting circuit 11 is adjusted in level by a gain control circuit 14 in accordance with the level detected by the level detecting circuit 13, and is supplied to the speaker 3a as a drive signal. Since this drive signal is a signal obtained by inverting and level-adjusting a signal corresponding to noise around the microphone 4a, a sound whose phase is inverted from the noise around the microphone 4a is output from the speaker 3a. Therefore, at the position of the ear of the user whose head is located near the headrest 2 of the bathtub 1, ambient noise is canceled or reduced.

As described above, since the noise elimination device for eliminating the noise near the headrest 2 of the bathtub 1 is provided, the user is troubled by the noise while the head is located near the headrest 2 of the bathtub 1. Without relaxing, you can enjoy a relaxing bath in a quiet environment.

In the above embodiment, the speakers 3a, 3b and the microphones 4a, 4b are buried in the bathtub 1, but the speakers 3a, 3b and the microphones 4a, 4
b may be attached to the bathtub 1 without being embedded in the bathtub 1. Further, the speakers 3a and 3b and the microphones 4a and 4b may be attached to the side wall of the bathroom. For example, when the user puts his / her head on the headrest 2 and the side wall of the bathroom is present near the back of the head, the speakers 3a and 3 are located slightly higher than the headrest 2 on the side wall.
b or microphones 4a and 4b may be attached.

In the above embodiment, among the components of the noise elimination device, components other than the speakers 3a and 3b and the microphones 4a and 4b are incorporated in the bath remote controller 6, but are independent of the bath remote controller 6. It may be built in a case that has been made.

In the above embodiment, two sets of speakers and microphones are provided in the noise elimination device, but the number of sets of speakers and microphones is arbitrary.

Further, in the above embodiment, the portion of the headrest 2 of the bathtub 1 is recessed. However, the portion of the headrest 2 does not necessarily need to be recessed, and the headrest 2 and other portions of the bathtub 1 cannot be distinguished. You may.

[0029]

As described above, according to the present invention, since the noise elimination device for eliminating noise near the headrest of the bathtub is provided, the user can position the head near the headrest of the bathtub. You can relax and enjoy the bath without being bothered by the noise.
