Description

  The present invention relates to a remote controller for a water heater, and more particularly, to a remote controller for a water heater in which hot water supply, chasing, etc. are performed automatically.

  Conventionally, in a water heater having an automatic hot water supply function such as a fully automatic bath apparatus, a hot water remote controller and a bath remote controller are provided, and hot water start and stop, hot water temperature change, bath temperature change, hot water volume change, heat retention time Input operation to command the operation of the water heater such as change, bath automatic operation start and stop, hot water start and stop, hot water temperature change, hot water start and stop, hot water amount change, lukewarm start and stop, etc. is performed by the switch It is like that. Furthermore, these remote controllers are provided with an acoustic guidance function for performing guidance by a buzzer, voice, or the like according to the input operation when the input operation is received, and the input operation content can be identified by sound. As a result, when an input operation is mistaken, it can be immediately recognized and corrected, and a dangerous state such as high-temperature hot water can be immediately notified to prevent an accident.

  However, by performing the acoustic guidance according to the input operation in accordance with the principle, the advantage of performing the acoustic guidance may be lost. For example, for an input operation that normally repeats the same operation, such as a hot water temperature change switch, generating the voice guidance every time an operation is accepted causes the same voice to be heard frequently, which is very troublesome. It will be. For input operations in which the same operation is repeated, voice guidance may be collectively performed after a series of operations. However, the purpose of performing voice guidance for input operations is to make sure that input operations are not mistaken, so it is necessary to perform guidance immediately after input operations. It is not preferred to do so.

  The present invention is intended to solve the above-described problem. When performing acoustic guidance in response to an input operation using a switch, a remote controller for a water heater that can perform appropriate acoustic guidance according to the input operation is provided. The purpose is to provide.

  In order to achieve the above object, a structural feature of the present invention is a remote control device for a water heater having an acoustic guidance function for notifying an acceptance state of an input operation commanding the operation of the water heater by sound, sound such as a buzzer, In the case where the input operation requires a repeated operation such as a numerical value setting, the voice guidance is omitted when the input operation is repeatedly received within a predetermined time.

  By configuring the present invention as described above, when an input operation that requires repeated operations such as numerical setting is repeatedly received within a predetermined time, the voice guidance is omitted, and thus the input operation is performed. Since the voice guidance is not generated every time the operation is accepted in a short period of time, the same voice is not frequently heard. On the other hand, when such an input operation is performed after a predetermined time has elapsed, voice guidance is performed, so that the contents of the input operation can be grasped.

  In the present invention, when an input operation that requires repeated operations such as numerical setting is repeatedly received within a predetermined time, voice guidance is omitted, so that the input operation can be clearly recognized. , The same voice is not frequently heard every time an operation is accepted in a short period of time.

Next, an example of the type of buzzer sound display and sound display generated by the switch operation of the hot water remote controller 70 and the bath remote controller 80 will be described.
As for the buzzer sound display, as shown in FIG. 13 (a), the start sound buzzer 2 used when hot water supply is started, the stop sound buzzer 3 used when hot water supply is stopped, and the hot water is high temperature. There are five types: a high-temperature buzzer 4 that warns the user, a 42 ° C. buzzer 5 that indicates the hot water temperature is 42 ° C., and a click sound buzzer 6 that indicates other cases. In the following description, a state where there is no buzzer is indicated by 1. Here, in the case of the start sound buzzer 2, 100 msec on−120 msec off−100 msec on−20 msec off is one unit. The other buzzers are as shown in FIG. Thereby, the state of the water heater can be determined from the operation mode of the buzzer.

  For voice display, as shown in Fig. 13 (b), "Hot hot water comes out 7" (1.2 seconds), "Change hot water temperature 8" (1.2 seconds), "Bath temperature Change 9 ”(1.0 seconds),“ Change the amount of hot water 10 ”(1.0 seconds),“ Change the heat retention time 11 ”(1.2 seconds),“ Spread 12 ” (1.0 second), “Atsume 14” (0.6 seconds), “Tashiyu 15” (0.6 seconds), “Nurume 16” (0.6 seconds), “melody sound + voice” There are 10 types of baths 13 ”(2.5 seconds).

Next, the buzzer display and voice display modes for the switch operation mode will be described. As shown in FIG.
A: Buzzer or sound. As an example, three types are included: buzzer only, buzzer + voice, and voice only.
B: The buzzer or sound being sounded is interrupted, and the next buzzer or sound is sounded. As an example, three types are included: buzzer only, buzzer + voice, and voice only.
C: If the same sound is repeated within 5 seconds using a combination of buzzer and sound, only the buzzer is used. As an example, two types are included when it is repeated and when it is not repeated.
D: When only sound is used, if the same sound is repeated within 5 seconds, there is no ringing. As an example, two types are included when it is repeated and when it is not repeated.
E: Operation sound is valid and there is no buzzer or sound
F: The next buzzer or sound is sounded after the sounding buzzer or sound ends. As an example, three types are included: buzzer only, buzzer + voice, and voice only.

  Table 1 below summarizes the buzzer and sounding status when the switch is operated in various states of the water heater.

  For example, when the hot water supply operation is started in the state of “no ringing 1”, since A: 2, the start sound buzzer 2 sounds immediately. In addition, when the hot water supply operation is started in the sound generation state of “hot hot water comes out”, since B: 2, the sound is interrupted and the start sound buzzer 2 sounds immediately, but the operation of raising the hot water temperature to a high temperature In the case of an operation for raising or lowering the temperature, a problem occurs in the hot water heater such as hot water having a high temperature coming out, and these input operations are invalidated.

  When the operation of raising or lowering the hot water supply temperature (42 ° C, low temperature), which is the same operation, is performed in the sound generation state of "Changing the hot water supply temperature", since the state is E, the sound generation state continues and the operation is accepted. It is done. When an operation for raising the hot water supply temperature (high temperature) is performed, since B is 4 + 7, the sound generation state is immediately interrupted, and a high temperature buzzer sounds and a sound “hot hot water comes out” is generated. Note that an operation such as lowering the hot water supply temperature (high temperature) is an impossible operation (indicated by “−” in the table).

  Also, when the switch is operated repeatedly, such as when changing the hot water supply temperature, if the operation is repeated within 5 seconds, such as C: 5 + 8, C: 6 + 8, only the buzzer will sound. Sound generation is omitted. Further, while the buzzer is sounding, as shown in states 2 to 6, all new input operations are invalidated.

  Next, the speaker ringing state when the display is changed by the switch operation is shown in Table 2 below.

  For example, if the temperature display is changed to a high temperature at the start of the hot water supply operation, since A: 7, “hot hot water comes out” is displayed as a voice when no ringing occurs. Also, if the display changes to a low temperature due to a change in hot water temperature, D: 8, so if it is repeated within 5 seconds, the sound generation will be omitted. ”Is generated. “No change” means that there is no change in the voice. Further, changes other than the display changes 1 to 9 shown in Table 2 are not changed and are not shown in Table 2.

Next, the operation of the embodiment configured as described above will be described.
By turning on the operation switch, the controller 60 of the water heater starts to execute the combustion operation control. On the other hand, when the hot water supply switches 73 and 83 of the hot water remote controller 70 or the bath remote controller 80 are turned on, the control unit 93 starts the “main program” at step 100 shown in FIG. 6 and simultaneously displays the “timer interrupt program shown in FIG. Is started at step 106.

  The control unit 93 performs initial settings of the CPU, I / O, etc., performs an initial setting of the interrupt state, and further sets initial data of various variables (steps 101 to 103). In the initial data setting, the operation invalid flag SMF is set to “0”, and the buzzer sound ringing request flag (hereinafter referred to as ringing request flag) BOMF and the ringing storage flag MKF are reset. The ringing request flag BOMF represents the ringing request for the buzzer sound displays 1 to 6 and the voice displays 7 to 16, and is represented by 16 types of BOMF1 to BOMF16 with numbers assigned thereto. The ringing storage flag MKF indicates that the buzzer sound indications 1 to 6 and the voice displays 7 to 16 are being ringing, and is represented by 16 types of MKF1 to MKF16 with respective numbers.

  Subsequently, the control unit 93 executes a “reception information analysis routine” for analyzing the reception information from the control unit 61 of the water heater (step 110), and further transmits the remote control 70, 80 to the control unit 61 of the water heater. A “transmission information setting routine” for setting information to be executed is executed (step 130). Thereafter, the control unit 93 executes a “buzzer / audio output routine” for setting buzzer and audio output based on the received information (step 150), and subsequently outputs to the display units 72 and 82 (step 104). ), Step 110, step 130, step 150 and step 104 are repeatedly executed. On the other hand, the control unit 93 starts interrupt execution of the “timer interrupt program” in step 106, controls the communication state related to data transmission / reception, and repeatedly reads input states of various switches (step 106). ~ 109).

  Hereinafter, the operation of both remote controllers 70 and 80 will be described based on an example of an input operation when a repeated operation is required as a switch operation in the embodiment. As an input operation example, the hot water supply switch 73 is turned on (the hot water supply temperature setting is low), and then the up switch 76a is changed within a predetermined time (within 5 seconds in this example) to change the temperature setting at a low temperature. This is a case of repeated operation.

  In the “reception information analysis routine”, as shown in FIG. 8, the execution of the program is started at step 110, and it is determined whether there is reception information at step 111. Here, since there is no reception information, “NO” is given. Once determined, the program is moved to step 120 and execution is terminated. In the “transmission information setting routine”, as shown in FIG. 10, when the execution of the program is started in step 130 and the switch is not turned on, the operation invalid flag SMF is reset to “0” and the transmission information is set. Is switched off (steps 131-134). The operation invalid flag SMF stores “1” when it is determined that the switch operation (input operation) is invalid, and stores “0” when it is not determined that the switch operation is invalid. It is a flag to disable until turned off.

  Here, since the hot water supply switch 73 is turned on, the program is moved to step 135, and it is determined whether or not the operation invalid flag SMF is “1”. Here, since it is not yet “1”, the program moves to step 136, and it is determined whether or not the previous switch is off. Here, since the previous switch is off, it is next determined whether or not a buzzer is sounding (step 137). Here, since the sound is not ringing, the program is moved to step 138 based on the determination of “NO”, the operation switch being turned on, that is, the hot water supply switch 73 is taken in as transmission information, and the execution of the program is finished (step 139). .

  Next, in the “buzzer sound output routine”, as shown in FIG. 11, execution of the program is started in step 150, and it is determined whether or not the buzzer sound is ringing (step 151). Therefore, the program is moved to step 152 based on the determination of “NO”, is not turned on and is in an off state, and further, since there is no request for a buzzer or sound, the execution of the program is terminated (steps 152 to 154). ). Subsequently, display output is performed (step 104), and the program is returned to step 110 again. During this time, the control unit 93 transmits the transmission information to the controller 60 through the communication circuit by executing the “timer interrupt program”, receives the information signal from the controller 60, and further reads the switch input. (Steps 107-109).

  In the “reception information analysis routine”, it is determined whether or not there is reception information. Here, since the reception information on the hot water supply switch 73 is sent, it is determined as “YES” and the program is moved to step 112. Then, the display data is updated, and it is determined whether or not there is an operation valid sound instruction (step 113). Here, since there is an operation effective sound instruction, the content is classified into A: 2 shown in Table 1 (steps 114 and 115). Further, the change in the display data is analyzed and the buzzer and the sound to be sounded are selected (steps 116 and 117). However, since there is nothing corresponding here, the second sounding request flag BOMF is set as a result.

  Subsequently, it is determined whether or not there is a buzzer sound request this time (step 118). Since A: 2 is classified as an operation effective sound here, the program is moved to step 121 based on the determination of "YES". . Here, “NO” is determined according to A: 2, and after the timer is reset (steps 121 and 122), the state with the received information is reset, and then the execution of the program ends (steps 119 and 120). . In the “transmission information setting routine”, steps 131, 135, 136, 138, and 139 are repeatedly executed until the switch is turned off. After the switch is turned off, steps 131 to 134 are executed as described above. Is done.

  Next, in the “buzzer sound output routine”, it is determined in step 151 whether or not the buzzer sound is being sounded. Here, since there is no sound, the process proceeds to step 152 based on the determination of “NO”. Since there is actually no ringing, it is determined in step 153 whether there is a buzzer or voice ringing request. Since there is a second ringing request, the program proceeds to step 155 based on the determination of “YES”, and the second start sound buzzer 2 is selected from the ringing request flag BOMF to identify the current buzzer. No. 2 starting sound is set from the ringing storage flag MKF, and a ringing sound phrase is further selected (steps 155 to 157). Further, the program is moved to step 158, the buzzer sound sound output is turned on, and the start sound buzzer 2 is sounded.

  While the start sound buzzer 2 is sounding, the program is returned from step 160 to the main routine. Further, “YES” is determined in step 151 and “NO” is determined in step 161, and the process proceeds to step 159. When the ringing of the start tone buzzer 2 ends, the program moves to step 162, the ringing request flag BOMF that was ringing currently is reset based on the ringing storage flag MKF, the ringing storage flag MKF is reset, and the ringing sound Is turned off (steps 162-164), the program ends (step 160). Next, a process for increasing the hot water supply temperature is performed by operating the up switch 76a.

  In the “reception information analysis routine”, it is determined in step 111 whether there is reception information. However, since there is no reception information here, it is determined “NO”, the program is moved to step 120, and the execution ends. In the “transmission information setting routine”, it is determined in step 131 that the up switch 76a is turned on, the program is moved to step 135, and it is determined whether or not the operation invalid flag SMF is “1”. Since “1” is not set here, the program moves to step 136 to determine whether or not the previous switch was off. Since it is off here, it is next determined in step 137 whether or not a buzzer is sounding. In this case, since the buzzer sound is not sounded, the program is moved to step 138 based on the determination of “NO”, the operation switch being turned on, that is, the up switch 76a is taken in as transmission information, and the execution of the program is finished ( Step 139).

  Next, in the “buzzer sound output routine”, it is determined in step 151 whether or not the buzzer sound is being sounded. Here, since there is no sound, the process proceeds to step 152 based on the determination of “NO”. Since there is no ringing and it is in an off state and there is no ringing request, the program execution is also terminated (steps 152 to 154). Subsequently, display output is performed (step 104), and the program is returned to step 110 again. During this time, the control unit 93 transmits the transmission information to the controller 60 through the communication circuit and receives the information signal from the controller 60 by executing the “timer interrupt program”.

  In the “reception information analysis routine”, it is determined in step 111 whether or not there is reception information. Here, since reception information with the up switch 76a turned on is sent, it is determined “YES” and the program is executed. The process proceeds to step 112 where the display data is updated and it is determined whether or not there is an operation valid sound instruction (step 113). Here, since there is an operation effective sound instruction, the content is classified into C: 6 + 8 shown in Table 1 (steps 114 and 115). Further, the change in the display data is analyzed, and the buzzer and the sound to sound are selected (steps 116 and 117). Here, it is also classified as D: 8, but the synthesized result is C: 6 + 8, giving priority to the operation. No. 8 ringing request is selected.

  Subsequently, it is determined whether or not the buzzer sound is requested this time and the buzzer sound setting corresponds to “C” or “D” in the table (steps 118 and 121). The program is moved to step 123 based on the determination “” and it is determined whether or not the timer is being counted. Since it is not counted here, it is determined as “NO”, and a timer start of 5 seconds is started (step 124). Thereafter, the state with the received information is reset, and the execution of the program ends (steps 119 and 120).

  In the “transmission information setting routine”, it is determined whether or not the operation invalid flag SMF is “1”. Here, since it was not set to “1” last time, the program moves to step 136 and it is determined whether or not the previous switch is off. Here, since the up switch 76a is on, the program is moved to step 138 based on the determination of “NO”, and the operation switch being turned on, that is, the up switch 76a is taken in as transmission information, and the execution of the program ends (step). 139).

  Next, in the “buzzer sound output routine”, it is determined whether or not the buzzer sound is sounding. However, since there is no sound here, the process proceeds to step 152 based on the determination of “NO”, and there is no sound. Therefore, it is determined in step 153 whether or not there is a buzzer or sound ringing request. Since there are ringing requests for No. 6 and No. 8, the program moves to Step 155 based on the determination of “YES”, and the buzzer of No. 6 and No. 8 in the ringing request flag BOMF has priority. The number 6 in the ringing storage flag MKF is set and a ringing sound phrase is selected (steps 155 to 157).

  Further, the program is moved to step 158 and the click sound buzzer 6 is activated. While the buzzer / sound is sounding, the program is returned from step 160 to the main routine. Further, “YES” is determined in step 151 and “NO” is determined in step 161, and the process proceeds to step 159. When the ringing is finished, the program is moved to step 162, the number 6 in the ringing request flag BOMF is reset based on the ringing storage flag MKF, the ringing storage flag MKF is reset, and the ringing sound is turned off. After (steps 162 to 164), the program ends (step 160). Subsequently, No. 8 “Change hot water temperature” is selected, and the voice guidance “Change hot water temperature” is sounded.

  In the “reception information analysis routine”, it is determined whether or not there is reception information. Here, since the reception information after ON switch 76a ON transmission is continuously sent, it is determined as “YES” and the program is executed in steps. 112, the display data is updated, and it is determined whether or not there is an operation valid sound instruction (step 113). Here, since there is an operation effective sound instruction, the content is classified into C: 6 + 8 shown in Table 1 (steps 114 and 115). Furthermore, the change in the display data is analyzed, and the buzzer and the sound to be sounded are selected (steps 116 and 117). Here, it is also classified as D: 8. However, since the synthesized result gives priority to the operation, C: 6 + 8. No. 6 and No. 8 ringing request flags BOMF are set.

  Next, whether or not the buzzer sound setting corresponds to “C” or “D” in the table is determined based on the request for the buzzer sound this time (steps 118 and 121), but the buzzer sound setting is C: 6 + 8. Therefore, based on the determination of “YES”, the program is moved to step 123 to determine whether or not the timer is being counted. Here, since the up switch 76a is turned on within 5 seconds and the timer is counting, the program moves to step 125 based on the determination of “YES”, cancels the selected voice number 8 and rings the number 6 Only the request flag BOMF is provided. Further, the timer is set again to 5 seconds (step 124), the state with the received information is reset, and then the program execution is terminated (steps 119 and 120).

  In the “transmission information setting routine”, since the up switch 76a is continuously turned on, the program is moved to step 135, and it is determined whether or not the operation invalid flag SMF is “1”. Here, since it was not set to “1” last time, the program moves to step 136 and it is determined whether or not the previous switch is off. Since it is on here, the program is moved to step 138 based on the determination of “NO”, the operation switch that is turned on, that is, the up switch 76a is taken in as transmission information, and the execution of the program ends (step 139).

  Next, in the “buzzer sound output routine”, it is determined whether or not the buzzer sound is sounding. However, since there is no sound here, the process proceeds to step 152 based on the determination of “NO”, and there is no sound. Therefore, it is determined in step 153 whether or not there is a buzzer or sound ringing request. Since there is a ringing request for No. 6, the program moves to Step 155 based on the determination of “YES”, No. 6 is selected from the ringing request flag BOMF, No. 6 of the ringing storage flag MKF is set, Further, a ringing sound phrase is selected (steps 155 to 157). Accordingly, when the sound output is turned on, the click sound buzzer 6 is only sounded, and the voice guidance “change hot water temperature” is not performed (step 158).

  That is, if the operation of the up switch 76a that generates the same ringing is performed within 5 seconds after the previous ringing, only the click buzzer 6 is ringed and the voice guidance “changes the hot water supply temperature” does not occur. . Subsequent operation of the up switch 76a also sounds only the click sound buzzer 6 within 5 seconds. However, in the case of the operation of the up switch 76a after 5 seconds have passed since the previous ringing, “NO” is determined in step 123 shown in FIG. 9, and the click buzzer 6 is ringed similarly to the previous time, Furthermore, the voice guidance “I will change the hot water supply temperature” is performed.

  As described above, when the operation of the up / down switches 76a and 76b that require repeated operations such as numerical setting is repeatedly received within a predetermined time, the click buzzer 6 only sounds and the “hot water supply temperature” The guidance of “I will change” is omitted, so that the input operation can be clearly recognized. Further, since the voice guidance “changes the hot water supply temperature” is not generated every time the operation of the up / down switches 76a and 76b is accepted in a short period of time, the same voice is not frequently heard. On the other hand, when the input operation of the up / down switches 76a and 76b is performed after a predetermined time has elapsed, the voice guidance “I will change the hot water supply temperature” is performed, so that the contents of the input operation can be grasped.

  The above embodiment is merely an example, but the present invention is also applied to operations for each state shown in Table 1 and display changes for each state shown in Table 2. In addition, what was shown to the said embodiment is an example, and can be implemented in various changes in the range which does not deviate from the meaning of this invention.

  In the present invention, when an input operation that requires repeated operations such as numerical setting is repeatedly received within a predetermined time, voice guidance is omitted, so that the input operation can be clearly recognized, The same voice guidance is not frequently heard, and when an input operation is performed after a predetermined time has elapsed, the voice guidance is performed, so that the contents of the input operation can be grasped, which is useful.
