In step S401, the user operates the voice recognition mode on / off switch of the manual operation unit 700 in advance to perform an instruction operation to turn on the voice recognition mode. Then, the mode switching unit 110 of the control unit 100 sets the storage unit 150 so that the warm water washing toilet seat device 10 can be operated in the voice recognition mode. This operation may be performed as an initial setting of the warm water washing toilet seat apparatus 10. When the voice recognition mode is on, as will be described later, when the seating determination unit 130 determines that the user is seated on the toilet seat body 310, the voice sensor 200 and the voice analysis unit 140 are set in an operating state. Thus, it is possible to accept voice instructions. Even when the voice recognition mode is set to ON, if the user is not seated on the toilet seat body 310, either one or both of the voice sensor 200 and the voice analysis means 140 are used. Stop operation. On the other hand, when the voice recognition mode is off, the voice sensor 200 and the voice analysis unit 140 remain in the non-operating state even when the seating determination unit 130 determines that the user is seated on the toilet seat body 310. Therefore, voice instructions are not accepted. In the following description, a case will be described in which an instruction for a buttocks cleaning function is given when a user is seated on the toilet seat body 310.

  In step S <b> 402, the seating determination unit 130 determines whether the user is seated on the toilet seat body 310 based on the output of the seating detection unit 320 of the heating toilet seat 300. When it is determined that the user is not seated on the toilet seat body 310, the user waits for seating. On the other hand, when it is determined in step S402 that the user is seated on the toilet seat body 310, in step S403, each function control unit 160 indicates a flag indicating ON / OFF of the voice recognition mode stored in the storage unit 150. , The voice sensor 200 is set to the operating state when the voice recognition mode is set to ON, and the voice analysis unit 140 is set to the operating state to enable the voice instruction to be received. Here, when the voice recognition mode is set to OFF, each function control unit 160 uses the voice by leaving both the voice sensor 200 and the voice analysis unit 140 in a non-operating state. Leave in a state that does not accept instructions.

  In subsequent step S404, the noise canceling means 120 removes the noise component by performing arithmetic processing based on the audio signal input from the audio sensor 200, that is, the first microphone 210 or the second microphone 220, and the user's audio. Only the signal component is left and output to the voice analysis means 140.

  In step S405, the voice analysis unit 140 determines whether or not a voice instruction is input by the user. If it is determined by the voice analysis means 140 that a voice instruction is input, the process proceeds to step S406. If it is determined that there is no voice instruction input, the process proceeds to step S407. In step S406, the voice analysis unit 140 recognizes what word the user has generated, compares it with the word by each user registered in advance in the storage unit 150, and uses the instruction associated with the matching word. The type of voice instruction acquired by the voice sensor 200 is specified by regarding the instruction as a person's instruction. For example, when the user generates the word “wet”, the voice analyzing unit 140 recognizes the word “wet” and recognizes the “washing start” registered in the storage unit 150 in association with “wet” in advance. Is specified as a user instruction, the type of the voice instruction specified in this way is stored in the storage means 150, and the process proceeds to step S408.

  In step S407, each function control unit 160 determines whether or not there is an operation instruction from the manual operation unit 700. When each function control unit 160 determines that there is an operation instruction from the manual operation unit 700, the function control unit 160 stores the content of the operation instruction in the storage unit 150, and proceeds to the process of step S408. On the other hand, when each function control unit 160 determines that there is no operation instruction from the manual operation unit 700, the process returns to the process of step S403.

  In step S <b> 408, each function control unit 160 executes control of each function based on an instruction specified based on a voice instruction stored in the storage unit 150 or an operation instruction from the manual operation unit 700. For example, the cleaning operation is started by discharging the cleaning water from the nozzle 430 of the hot water cleaning device 400 based on the “start cleaning” instruction specified based on the word “wet” of the user.

  In step S <b> 409, the seating determination unit 130 determines whether or not the user is seated on the toilet seat body 310 based on the output of the seating detection unit 320 of the heating toilet seat 300. If it is determined that the user is not seated on the toilet seat body 310, the process proceeds to step S410. If it is determined that the user is seated on the toilet seat body 310, the process returns to step S403. Wait for detection of instructions by voice.

  In step S410, each function control unit 160 stops receiving voice instructions by turning off the voice sensor 200 or turning off the voice analysis unit 140. Further, for example, when it is determined that the user is not seated from the toilet seat body 310 during the cleaning operation, each function control unit 160 stops the operation of the hot water cleaning device 400 and immediately ends the cleaning operation.

  As described above, in the warm water washing toilet seat device 10 of the present embodiment, the voice sensor 200 configured by the first microphone 210 and the second microphone 220 arranged at different positions is used to collect the voice instruction of the user. To do. The noise canceling unit 120 performs arithmetic processing based on the audio signals input from these two microphones to remove the noise component and leave only the user's audio signal component, thereby improving the accuracy of audio recognition. It becomes possible.

  In particular, the first microphone 210 is disposed on the right or left side of the control box 340 of the heating toilet seat 300, and the second microphone 220 is disposed on the sleeve switch unit 710 or the remote controller 720. It is easy to collect noise or noise caused by various driving sounds (such as the intake fan 610 of the deodorizing device 600) generated from the main body of the warm water washing toilet seat 10, and the second microphone 220 relatively easily collects the user's voice. Based on the difference between the two audio signal components, only the user's audio component can be extracted.

  In the above embodiment, the case where two microphones are provided as the sound sensor has been described. However, the present invention is not limited to the above, and three or more microphones may be provided. Further, the installation position of the first microphone is not limited to the control box 340, and may be arranged at another position, for example, the toilet seat body 310 or the toilet lid 800. Further, the installation position of the second microphone is not limited to the front side surface of the sleeve switch unit 710, and may be arranged at another position.

  Further, in the warm water washing toilet seat device of the present embodiment, the seat determination unit 130 determines that the user is seated on the toilet seat body 310 based on the output from the seat detection unit 320 provided in the heating toilet seat 300. Only when the first microphone 200, the second microphone 220, and the voice analysis means 140 are in an operating state, and a voice instruction from the user can be received. Therefore, when the user is not seated on the toilet seat main body 310, a voice such as “butt” or “wash” is unintentionally uttered, or a voice instruction word associated with each operation instruction is intentionally uttered. Even in such a case, it is possible to prevent a malfunction such as a cleaning operation being started based on that, or a cleaning water splashing around.

  Further, in the above embodiment, the user can set the voice recognition mode on or off, and if the voice recognition mode is turned off, all of the voice recognition modes can be used regardless of whether the user is seated or not. Since voice instructions are not accepted, erroneous operations based on voice recognition can be prevented.

  In the above description, an example in which a washing start operation is performed when a voice instruction such as “wet” is received while the user is seated on the toilet seat body 310 has been described. When the user is seated on the toilet seat body 310 by means 130, voice instructions such as bidet cleaning, drying, stopping, and adjustment of the strength of the washing water may be accepted.

  Furthermore, in the above description, an example in which a voice instruction is received only when the user is seated on the toilet seat body 310 has been described. However, the present invention is not limited to the above-described embodiment. 1), the first microphone 210, the second microphone 220, and the voice analysis means 140 are activated, and the toilet water is “flowed”. Can be received, but voice instructions such as butt washing, bidet washing, drying, and stopping are not executed, and the seating determination unit 130 determines that the user is seated on the toilet seat body 310. Only after that, voice instructions such as butt washing, bidet washing, drying, and stopping may be executed. In this case, each function control unit 160 determines and executes a voice instruction that is permitted at each condition at the time of presence determination and seating determination.
