Description

  The present invention relates to a warm water washing toilet seat that discharges warm water obtained by a warm water generator from a nozzle and performs butt washing or butt washing and bidet.

  In recent years, warm water flush toilet seats are becoming widespread not only in public facilities but also in general houses. The warm water washing toilet seat is for discharging hot water from a nozzle by operating a switch to wash a local area after a user's toilet. In recent years, in addition to the cleaning function, there are functions that have a massage function and a drying function, as well as functions that adjust the water flow and position of the cleaning water, the temperature of the hot water, etc. This is done by operating switches installed on the remote controller installed on the wall and the sleeve switch part of the heated toilet seat.

  Such a switch operation has a problem that it is very troublesome and difficult to use for an elderly person who is not good at fine operation. Some people do not want to touch the switch as much as possible because of hygiene issues. Therefore, a warm water washing toilet seat having a voice operation function has been developed.

  An example of a cleaning toilet seat having a voice operation function is disclosed in the following Patent Document 1 (Japanese Patent Laid-Open No. 2005-97944). The “local cleaning device” disclosed in the following Patent Document 1 is an operation instructed by the user by comparing the voice of the user input and identified from the sound receiving unit with the voice data stored in advance. The voice operation is enabled by specifying the contents and transmitting the operation to the main body control circuit based on the specified operation contents.

  Also, an example of a cleaning toilet seat that identifies voice for each individual and operates according to setting conditions according to the individual is disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 07-216966). The “sanitary washing toilet seat device” disclosed in the following Patent Document 2 identifies the individual user by the voice of the user and operates according to the desired setting conditions for each individual, for example, if it is a washing operation, The position, the strength of the cleaning, the cleaning time, etc. are configured so that the user can operate in a preferred state.

  However, in the cleaning toilet seat having the voice operation function disclosed in Patent Document 1, the timing for receiving the voice operation has not been specified. For this reason, if the user does not make an unintentional sound such as “cleaning” while not sitting on the toilet seat (or if it is intentionally made), the cleaning nozzle will discharge cleaning water according to the sound instruction. There was a problem that it erupted and scattered around.

  The warm water washing toilet seat device according to the present invention has user identification means for identifying a user. The user identification unit is configured to identify a user by selecting, for example, a plurality of users registered in the storage unit in advance from the operation unit, or includes a voice sensor and is input from the voice sensor. The voice signal may be analyzed to identify a user and to specify a control instruction corresponding to the voice signal. In the following description, the present invention will be described in detail based on the latter configuration.

  As shown in FIG. 1, a warm water flush toilet seat device 10 having a voice operation function according to an embodiment of the present invention is used by being placed on a rim portion 22 of an upper peripheral portion of a toilet bowl 21 constituting a western toilet bowl 20. Is. As shown in FIGS. 1 to 3, the hot water cleaning toilet seat device 10 includes a control unit 100, a human sensor 200, an audio sensor 220, a receiving unit 240, a heating toilet seat 300, a hot water cleaning device 400, a hot air drying device 500, and a deodorization. The apparatus 600 includes a manual operation unit 700 and a toilet lid 800.

  The control unit 100 includes a CPU, a ROM, and a RAM (not shown), and each unit constituting the control unit described below by executing a control program recorded in the ROM on the CPU. The operation of each part of the warm water washing toilet seat apparatus 10 is controlled and integrated.

The function control means 160 controls each control object part of the warm water washing toilet seat apparatus 10, for example, parts, such as a washing nozzle position control part and a washing water / water force control part.

  The mode switching unit 110 switches between a voice recognition mode and a voice non-recognition mode based on an operation of a manual operation unit 700 described later. When the warm water washing toilet seat device 10 of the present embodiment is set to the voice recognition mode by the mode switching means 110, the occupancy determination means 120 is based on the output from the human sensor 200 and there is a user in the toilet. Both of the conditions when it is determined that the user is seated, and when the seating determination unit 130 determines that the user is seated on the toilet seat body 310 based on the output from the seating detection unit 320, or either When one of the conditions is satisfied, the voice sensor 220 and the voice analysis unit 140 are set in an operating state, whereby all voice instructions or a part of voice instructions by the user can be received.

  On the other hand, when the warm water washing toilet seat device 10 is set to the voice non-recognition mode by the user, it is determined that the user is in the toilet, or the user is placed on the toilet seat body 310. Even if it is determined that the user is seated, both or one of the voice sensor 220 and the voice analysis means 140 are in a stopped state, and cannot accept all voice instructions from the user.

  It should be noted that under what conditions when the voice recognition mode is set, whether the voice sensor 220 or the voice analysis unit 140 is in an operating state is determined by the user in advance when the initial setting or the voice recognition mode is set. And stored in the storage means 150. In the following description, an example will be described in which the voice sensor 220 and the voice analysis means 140 are put into an operation state when it is determined that the user is seated on the toilet seat body 310 based on the output from the seating detection unit 320. .

  The occupancy determination means 120 analyzes the output from the human sensor 200 described later, and whether or not there is a user in the toilet in which the hot water washing toilet seat device 10 of the present embodiment is installed or is used. It is determined whether the person has entered the toilet and has left the toilet. For example, when the occupancy determination unit 120 determines that the user has entered the toilet, the function control unit 160 instructs the energization of the toilet seat heater 330 of the heating toilet seat 300 to start heating the toilet seat body 310.

When it is determined by the occupancy determination means 120 that the user has left the toilet, the function control means 160 stops energization of the toilet seat heater 330 of the heating toilet seat 300 and stops heating the toilet seat body 310. Further, the function control means 160 outputs an instruction to close the stool lid 800 to the opening / closing means 810.

  The seating determination unit 130 determines whether or not the user is seated on the toilet seat body 310 based on the output from the seating detection unit 320 of the heating toilet seat 300.

  The voice analysis unit 140 filters the voice signal collected by the voice sensor 220 and recognizes what word the user has generated. Speaker identification is performed as follows. It is assumed that a voice signal input by the user includes a personal identification voice signal for identifying an individual, for example, a number or a symbol, and the storage area of the storage unit 150 is previously stored with the number, symbol, or personal name (name or father). And moms) and users are set in association with each other, and each user specifies the corresponding numbers, symbols or personal names in advance and registers their voice instructions.

  In this way, it is possible to identify a speaker by simply recognizing numbers, symbolic speakers, or individual names without performing spectrum analysis or voiceprint analysis of the input speech signal. The speaker identification accuracy can be improved by the means. Since the number of toilet users is limited to a few family members, the personal identification voice signal only needs to correspond to a limited number of people and does not need to be set innumerably. Further, the user may be specified by a method other than voice analysis.

  The storage unit 150 stores a word registered by each user and each operation instruction in association with each other. For example, the user's word “cleaning” is stored in association with an instruction to start hot water cleaning. Similarly, a washing stop instruction is associated with the word “stop” input by the user and stored in the storage unit 150.

  Note that a plurality of user words may be stored in association with one control instruction, and similarly, a plurality of words of the same user, for example, an instruction to start hot water washing, for one control instruction. In addition to “washing”, words such as “washing” and “buttock” may be associated with each other. In this case, even if the user utters any of the words “washing”, “washing”, and “wet”, it is considered that the same hot water washing start control instruction is given, and the function control means 160 (to be described later) 400 is instructed to start washing with warm water.

  A storage area for each individual user is set in the storage means 150, and the personal identification voice information and voice instruction information described above are stored in the personal correspondence storage area for a predetermined period of time. The operation conditions (for example, the operation conditions such as the position of the cleaning nozzle and the water flow of cleaning water) are stored. The operation conditions are stored in a first-in / first-out manner. For example, the latest operation conditions for the most recent one week are always stored.

  When executing the control instructed by voice, the function control means 160 obtains the driving conditions corresponding to the identified user from the storage means, and is set most with reference to each of the acquired driving conditions. The operation condition is specified as the current operation condition, and the operation (operation) of each control target part is controlled. In this way, the most recent driving conditions are always memorized, the most frequently set driving conditions are identified and the control target part is controlled, so the physical condition and defecation status of the day for each individual who uses the toilet seat It is possible to dynamically set the operating conditions that change depending on.

  The function control means 160 is a user's input operation from the manual operation section 700, or a voice instruction specified by the voice analysis means 140. Furthermore, the mode switching means 110, occupancy determination means 120, seating determination of the control section 100. Based on the output from the means 130, etc., an instruction is outputted to each part of the warm water washing toilet seat 10, and the operation of each part is controlled.

In the storage area for each user, personal identification voice information and voice instruction information input in advance are registered.

  The personal identification voice information is, for example, numbers or symbols or individual names for identifying individual users. The voice instruction information is, for example, an operation instruction for each part of the warm water washing toilet seat device 10, and FIG. 4 illustrates an example in which the instruction information (word) of the user A instructing “washing” of the buttocks is registered. The user's word “cleaning” is stored in association with a warm water cleaning start instruction. Further, as described above, in addition to “cleaning”, words such as “washing” and “butting” may be associated as words for the instruction to start the hot water cleaning. In this case, even if the user utters any of the words “washing”, “washing”, and “wet”, it is considered that the same hot water washing start control instruction is given, and the function control means 160 (to be described later) 400 is instructed to start washing with warm water. The same applies to driving instructions for other parts to be controlled.

  These voice instruction information storage areas are each control target part in the hot water cleaning, in the example of FIG. 4, for example, the operating conditions of each control target part such as the nozzle position and the cleaning water flow, It is configured to store the data in a first-out method (a method in which first stored data is deleted first and new data is added and stored).

  The predetermined span is a predetermined period (for example, one week) or a predetermined number of uses (for example, 20 times). Therefore, the latest operating conditions are always stored in the storage unit 150 for each user for each control target part during the span. The function control unit 160 specifies the most frequently specified driving condition among the driving conditions stored for each control target part stored in the storage unit 150 as the current driving condition, and controls the operation of the control target part. In the following description, it is assumed that the predetermined span is a predetermined period, for example, one week.

  For example, in response to the voice instruction “cleaning” of the user A in FIG. 4, the most frequently set condition, for example, the water pressure among the operation conditions for the most recent one week in the control target portion “cleaning water water flow” 1 (weak) to 5 (strong) can be set in 5 stages, and when the most frequently set condition is 3 in the middle, the water condition “3” is specified as the current condition, and the function control means 160 controls the washing water to be ejected at a water pressure “3”. If the data to be stored is less than a predetermined span (for example, until one week elapses), the most recently stored operating condition may be set as the current operating condition.

  In addition, when the function control means 160 specifies the most frequently set condition wash water flow among the operation conditions for one week, a specific operation condition (in this case, wash water flow) is performed by the manual operation unit 700 by the user A. Is set, the most frequently set operating condition is changed to the operating condition set by the manual operation unit 700 to be the current operating condition. In other words, if there is any operating condition set by manual operation, the set operating condition is given priority as the current operating condition.

  Next, operation | movement of the warm water washing toilet seat apparatus 10 of this embodiment is demonstrated with reference to the flowchart shown in FIG. In step S101, 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. 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 S102, the occupancy determination means 120 determines whether or not the user is present in the toilet in which the warm water washing toilet seat device 10 is installed based on the output from the human sensor 200, or whether or not the user has entered the room. Determine whether. If it is determined that the user is not in the room or has not entered the room, the occupancy determination unit 120 waits for processing until it is determined that the user is in or out of the room.

  If it is determined that the user is in the room or has entered the toilet, in step S103, the function control means 160 controls the energization start of the toilet seat heater 330 of the heating toilet seat 300, and the heating toilet seat 300 Heating is started. Further, the function control means 160 outputs an instruction to open and close the toilet lid 800 to the opening / closing means 810, and the toilet lid 800 is automatically flipped up.

  In step S104, the function control unit 160 refers to the flag indicating ON / OFF of the voice recognition mode stored in the storage unit 150, and sets the voice sensor 220 to the operating state when the voice recognition mode is set to ON. In other words, the microphone is turned on, and the voice analysis means 140 is set in an activated state, thereby enabling a voice instruction to be accepted.

  In step S <b> 105, the voice analysis unit 140 determines whether or not a voice instruction is input from the voice sensor 220. If the voice analysis unit 140 determines that a voice instruction is input, the process proceeds to step S106. If it is determined that no voice instruction is input, the process returns to step S104 and waits for a voice instruction input.

  In step S106, the voice analysis means 140 filters the voice signal acquired via the voice sensor 220, and recognizes what word the user uttered. As described with reference to FIG. 4, the beginning of the input voice information includes personal identification voice information such as numbers and symbols for identifying the user or a personal name. Therefore, the voice analysis means 140 only recognizes the spoken word, and does not perform complicated analysis such as analysis of the voice spectrum, determination of the degree of coincidence with the user's voice data, which is pronounced in advance and stored. An individual can be identified (step S107).

  When the user is identified, the voice analysis unit 140 recognizes a voice signal continuously input by the user, compares it with a word by each user registered in advance in the storage unit 150, and indicates an instruction associated with the matching word. Is identified as a user instruction, the type of voice instruction acquired by the voice sensor 220 is specified (see FIG. 4). Hereinafter, a case where the user is A and the user A has generated the word “wet” will be described as an example. The voice analysis means 140 compares the word registered and stored in advance in the area of the user A of the storage means 150 by the user A, recognizes the matching word, that is, the word “wet”, and stores it in the storage means 150 in advance. The instruction of “start cleaning” registered in association with “wet” is specified as the instruction by the user.

  When the voice instruction is specified, in step S108, the function control unit 160 acquires the driving conditions for one week stored in the area of the user A in the storage unit 150. For example, as shown in FIG. 4, in response to the voice instruction “cleaning” by the user A, the operation conditions for the latest one week at the control target portion “cleaning water / water flow” and “nozzle position” are acquired.

  Next, in step S109, the function control means 160 specifies the most frequently set operating condition among the acquired operating conditions. For example, the water flow can be set in 5 steps from 1 (weak) to 5 (strong), and when the most frequently set operating condition is 3 in the middle, the water flow “3” is specified as the current condition. Then, the function control means 160 prepares for control so that the washing water is ejected at the water force “3”.

  In step S110, the function control unit 160 determines whether or not there is an operation instruction from the manual operation unit 700. When it is determined that there is no operation instruction from the manual operation unit 700, the function control unit 160 proceeds to the process of step S111, and the operation condition specified in step S109 (the most frequently set operation condition) is set as the current operation condition. Set and execute voice instructions. In the above case, the washing water flow “3” is specified, and the function control means 160 ejects the washing water at the water flow “3”.

  On the other hand, if the function control unit 160 determines that there is a report operation instruction from the manual operation unit 700, the process proceeds to step S112. Here, a case will be described in which the user A sets the washing water power to a weak “1” from the manual operation unit 700. In that case, the function control means 160 updates the water force “3” of the operation condition (the operation condition set most frequently) identified in step S109 to the water force “1” set from the manual operation unit 700, and this operation condition. And execute voice instructions. In the above case, the washing water is ejected with the water force “1”.

  When the execution of the voice instruction is completed in step S111 or step S112, the function control unit 160 stores the executed current driving condition in the driving condition storage unit for one week in the storage area of the user A of the storage unit 150. In storing, the oldest stored operating condition is deleted.

  When the operating condition is stored in the storage unit 150, the process proceeds to step S114. In step S114, the occupancy determination means 120 determines whether there is a user in the toilet in which the warm water washing toilet seat device 10 is installed or whether the user has left the room based on the output of the human sensor 200. . If it is determined that the user is not in the room or has left the room, the process proceeds to step S115. If it is determined that the user is still in the room, the process returns to step 104. Wait for user voice instructions.

  In step S <b> 115, the function control unit 160 controls to stop energization of the toilet seat heater 330 of the heating toilet seat 300 and stops heating the heating toilet seat 300. Further, the function control means 160 outputs an instruction to control the closing of the toilet lid 800 to the opening / closing means 810, whereby the toilet lid 800 is automatically closed and the processing is ended.

  Of course, the processing in steps S104 to S113 is performed not only on the buttocks cleaning but also on each control target portion of the warm water cleaning toilet seat 10.

  As described above, according to the warm water washing toilet seat device 10 of the present invention, each of the operating conditions is stored in the storage area for each user for the most recent predetermined span, and the function control means 160 acquires Each of the operating conditions is referred to, and the operation condition set most often is specified as the current operating condition to control the operation of the hot water cleaning apparatus. Therefore, driving conditions that vary depending on the physical condition of the day and the state of defecation can be dynamically set for each individual who uses the toilet seat.

  Further, according to the hot water washing toilet seat apparatus 10 of the present invention, the voice analysis means 140 identifies the user based on the personal identification voice signal of the speaker included at the head of the voice signal, and the personal identification voice signal is used in advance. Since it is either a number, a symbol or an individual name determined for each person, it is possible to improve the accuracy of personal identification based on voice data with a simple configuration.

  In addition, in the warm water washing toilet seat apparatus 10 of this invention, it is possible to add the various deformation | transformation described below. For example, 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. Only when it is determined that the user is seated on the toilet seat main body 310, the voice sensor 220 and the voice analysis means 140 can be set in an operating state to receive voice instructions from the user.

  As a result, when the user is not seated on the toilet seat body 310, a voice such as “butt” or “wash” is unintentionally emitted, or a word of a voice instruction associated with each operation instruction is intentionally generated. Even in such a case, it is possible to prevent a malfunction such as a cleaning operation being started based on this, and the cleaning water being scattered around.

  Of the switches provided in the manual operation unit 700, the buttocks washing switch, bidet washing switch, drying switch, stop switch, and move switch are not seated on the toilet seat body 310 by the seating determination means 130. If it is determined, the functions do not operate as in the case of the voice operation described above even if the user operates. On the other hand, the water temperature adjustment switch, water adjustment switch, toilet seat temperature adjustment switch, voice recognition mode on / off switch, and power saving setting switch accept various operations regardless of whether the user is seated on the toilet seat body 310 or not. May be performed.

  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. Is determined to be in the toilet, the voice sensor 220 and the voice analysis means 140 are in an operating state and can receive a voice instruction such as “flowing” the toilet water. Voice instructions such as bidet cleaning, drying, stopping, etc. are not executed, and only when the seating determination means 130 determines that the user is seated on the toilet seat body 310, such as butt cleaning, bidet cleaning, drying, stopping, etc. A voice instruction may be executed. In this case, the function control means 160 determines and executes a voice instruction that is permitted in each condition at the time of occupancy determination and seating determination.

  In the above description, the most frequently set driving condition (step S109 in FIG. 5) among the driving conditions for one week acquired from the storage unit 150 and the driving condition set by the user using the manual operation unit 700 are described. When the difference exceeds a predetermined range, the function control unit 160 is configured to set the most recently set operating condition as the current operating condition in place of the most frequently set operating condition in the subsequent processing. You can also

  For example, a user operating with normal wash water set to a strong “5” may change the setting to a low “1” using the manual operation unit 700 according to changes in physical condition such as hemorrhoids and diarrhea. In this case, it is more realistic for the user to use the most recent operation condition (weak water force “1”) as the current operation condition instead of the most frequently set operation condition (high water force “5”). This period can also be set as a certain period until the physical condition improves.
