The control unit 20 controls, for example, operation start, operation stop, temperature, and air volume of the air conditioner installed in the washroom based on the voice operation of the user.

The control unit 20 controls the operation of the device 30 provided in the bathroom and the device provided in the washroom based on the wake word and the operation word collected by the voice collection unit 10. A wake word is a specific word for starting a voice operation. The operation word is a word about an instruction for operating the device 30.

The control unit 20 has a state in which the operation word can be received and a state in which the operation word cannot be received. The control unit 20 maintains the state in which the operation word is not accepted until the voice collection unit 10 detects the wake word issued by the user. When the control unit 20 detects the wake word issued by the user by the voice collection unit 10, the control unit 20 becomes ready to accept the action word. In other words, the wake word is a voice command for switching the control unit 20 from the state of not accepting the action word to the state of accepting the action word. The control unit 20 controls the operation of the device 30 based on the content of the action word when the voice collection unit 10 detects the action word emitted by the user in a state in which the action word can be accepted. In other words, the operation word is a voice command for instructing the device 30 to be operated and the content of the operation.

The control unit 20 may be connected to the cloud CL via the Internet, for example. In this case, the wake word and the action word may be determined (voice recognition) by the control unit 20 or may be determined by the cloud CL. Further, a part of the wake word and the action word may be determined by the control unit 20, and the other may be determined by the cloud CL.

For example, the wake word is determined by the control unit 20, and the action word is determined by the cloud CL. As described above, the wake word is determined by the control unit 20 and the action word is determined by the cloud CL, so that the action word can be accepted as compared with the case where both the wake word and the action word are determined by the cloud CL. The time to become can be shortened. As a result, the time from when the user issues the wake word and the operation word to when the operation of the device 30 is executed can be shortened, and the usability can be improved.

Even if the voice collecting unit 10 detects the voice uttered by the user, if the control unit 20 cannot determine that the content of the voice is a preset wake word or action word, the wake word. It is considered that no motion word is detected.

Etc.), the bathtub 60, and/or the washroom 90 may be included.

FIG. 3 is a table showing an example of wake words and action words in the first mode and the second mode of the bathroom system according to the embodiment.
As shown in FIG. 3, the control unit 20 has a first mode and a second mode. In the first mode, the control unit 20 enters a state in which it is possible to receive the operation word by the different wake words set for each of the plurality of devices 30. In the second mode, the control unit 20 enters a state in which it can accept the operation word by the wake word common to the plurality of devices 30.

In the first mode, different wake words are set for each of the plurality of devices 30. Furthermore, when the device 30 has a plurality of functions, different wake words may be set for each of the plurality of functions.

For example, in the first mode, when the wake word for the heating function of the air conditioner 32 is “heating” and the operation word for designating the start of the heating function of the air conditioner 32 is “turn on”, the user indicates “heating”. It is possible to start the operation of the heating function of the air conditioner 32 by saying "Turn on". Other devices 30 and functions can also be operated by, for example, the wake word and operation word illustrated in the table of FIG. Note that the wake word and the operation word shown in FIG. 3 are examples, and the wake word and the operation word in the embodiment are not limited thereto.

In the second mode, a wake word common to the plurality of devices 30 is set. The common wake word in the second mode is, for example, “TOTO” or “flow”.

For example, in the second mode, when the common wake word is “TOTO” and the operation word for designating the start of the heating function of the air conditioner 32 is “Turn on heating”, the user selects “TOTO, turn on heating”. ", the operation of the heating function of the air conditioner 32 can be started. Other devices 30 and functions can also be operated by the operation words illustrated in the table of FIG. 3, for example. Note that the wake word and the operation word shown in FIG. 3 are examples, and the wake word and the operation word in the embodiment are not limited thereto.

As shown in FIG. 3, in the second mode, the operation word has an operation device word and an operation content word. The operating device word is a word for designating the device 30 and the function to be operated. The operation content word is a word for designating the operation content of the device 30 and the function. In the above example, the operation device word is “heating” and the operation content word is “turn on”. As described above, in the second mode in which the wake word common to the plurality of devices 30 is set, the user needs to issue the operation device word in order to specify the device 30 and the function to be operated.

On the other hand, as shown in FIG. 3, in the first mode, different wake words are set for each of the plurality of devices 30. Therefore, when the control unit 20 detects the wake word, the control unit 20 can detect the device 30 or the function to be operated by the detected wake word. Therefore, in the first mode, the user does not need to issue the operation device word after the wake word. In other words, in the first mode, the user can omit uttering the operating device word. As shown in FIG. 3, in the first mode, the operating device word in the second mode can be regarded as the wake word, and the wake word in the second mode can be considered to be omitted.

As described above, by setting different wake words for each of the plurality of devices 30, the device 30 to be operated can be designated by the wake word. As a result, the operating device word can be omitted and a smoother operation can be performed, and usability can be improved.

The first mode and the second mode can be switched. Switching between the first mode and the second mode is performed by, for example, the remote controller 75 in the bathroom. The switching between the first mode and the second mode may be performed by the toilet remote controller 95.

In this way, it is possible to switch between the first mode in which different wake words are set for each of the plurality of devices 30 and the second mode in which the wake word that is common to the plurality of devices 30 is set. , The usability can be improved. For example, when bathing alone, a smoother operation can be performed and usability can be improved by setting the first mode in which the operating device word can be omitted. In addition, when a plurality of people take a bath, by setting the second mode in which an erroneous operation is less likely to occur, it is possible to prevent the erroneous operation from occurring in the conversation between the users and improve the usability.

Further, the device 30 capable of performing the voice operation may be different between the first mode and the second mode. Since the water discharger 31 may discharge cold water or hot water, it has a great influence on the safety of the user when an erroneous operation occurs. On the other hand, the air conditioner 32 and the lighting device 33 have little influence on the safety of the user when an erroneous operation occurs.

Therefore, in the embodiment, for example, when the device 30 has the first device 30a including the water discharge device 31, and the second device 30b including at least one of the air conditioning device 32 and the lighting device 33, the control unit 20. Makes it possible to accept the voice operation for the second device 30b and not the voice operation for the first device 30a in the first mode, and the voice operation for the first device 30a and the second device 30b in the second mode. Can be accepted.

In this way, when the erroneous operation occurs, the voice operation of the first device 30a such as the water discharger 31, which has a great influence on the safety of the user, is performed only in the second mode in which the erroneous operation is less likely to occur, and the erroneous operation occurs. In this case, the voice operation of the second device 30b such as the air conditioner 32 and the lighting device 33, which has a small influence on the safety of the user, is performed in both the first mode and the second mode to improve the safety. The usability can be improved.
