Description

  The present invention relates to a plurality of capacitance type touch switches arranged in parallel, and a touch operation for each of the plurality of touch switches based on the capacitance value output from each of the plurality of touch switches. The present invention relates to a bath operating device provided with operation determining means for determining presence or absence.

  Such a bath operation device is used, for example, to configure a bath remote controller for a water heater for supplying hot water to a hot water tap or a shower tap in the bathroom, and the bath remote control is installed in the bathroom. In addition, it is conceivable that the bath operating device is used to configure a remote controller for a bathroom heater / dryer or a remote controller for a television set in the bathroom, and these remote controllers are also installed in the bathroom.

  As a conventional example of a bath operating device, a pair of touch switches is provided as a set, a plurality of switch sets are provided, and a difference between the capacitance values of the pair of touch switches of each switch set is obtained, and the obtained allowable capacitance value Based on the difference between the pair of touch switches, none of the pair of touch switches is touch-operated, one of the pair of touch switches is touch-operated, and the other of the pair of touch switches is touch-operated When there are a plurality of switch sets in which any one of the pair of touch switches is touch-operated, it is determined that the touch operation is not performed. (For example, refer to Patent Document 1).

  That is, in the bath operating device of Patent Document 1, when hot water adheres to the operation surface on which the touch operation of the bath operating device is performed, the capacitance value of the touch switch changes, and the hot water is obtained by performing a shower bath. Is attached to the operation surface, in view of the fact that hot water adheres over an area corresponding to the plurality of touch switches, there are a plurality of switch sets in which one of the pair of touch switches is touch-operated. If present, it is determined that the touch operation has not been performed, assuming that the hot water used in the shower bath is attached to the bath apparatus.

  Furthermore, the bath operation device of Patent Document 1 is configured to calculate the temporal integration value of the difference in capacitance value even when it is determined that any one of the pair of touch switches of one switch set is touched. In other words, when the temporal integration value is larger than the set threshold value, it is determined that the touch operation has been performed, and when the temporal integration value is smaller than the set threshold value, it is determined that the touch operation on the pair of touch switches has not been performed. Is configured to do.

  That is, in view of the fact that the hot water adhering to the operation surface that performs the touch operation of the bath operation device immediately flows down, it is determined that the operation on the pair of touch switches is not performed when the temporal integration value is smaller than the set threshold value. It is what I did.

  As described above, in the bath operation device of Patent Document 1, when there are a plurality of switch sets in which any one of the pair of touch switches is touched, or the temporal integration value of the difference between the capacitance values is more than the set threshold value. If it is smaller, it is determined that there is no touch operation.

  That is, the bath operation device of Patent Document 1 is a mode in which a pair of touch switches is provided as a set, a plurality of switch sets are provided, and a difference in capacitance value between the pair of touch switches of each switch set is obtained. The determination means is not configured to determine the presence or absence of a touch operation for each of the touch switches based on the capacitance value output from each of the plurality of touch switches, but the adhesion of hot water when performing a shower bath A technique for avoiding misjudgment due to is described.

JP 2012-243072 A

  When the operation determination unit determines whether or not there is a touch operation for each touch switch based on the capacitance value output from each of the plurality of touch switches, the technique of Patent Document 1 is used to perform a shower. It may be possible to avoid misjudgment due to adhesion of hot water when bathing.

  In other words, the operation determining means determines that there is a touch operation for a touch switch whose capacitance value has changed more than a setting determination value for determining the presence of the touch operation among the plurality of touch switches. However, as a first form for avoiding erroneous determination, when the operation determination unit includes a plurality of touch switches whose capacitance value changes to a setting determination value or more, all of the plurality of touch switches are detected. It may be configured to determine that there is no touch operation.

  Further, as a second form for avoiding erroneous determination, the operation determination means has a change time in which the capacitance value changes to a set determination value or more among the plurality of touch switches is equal to or longer than the erroneous determination avoidance time. A certain touch switch may be configured to determine that there is a touch operation.

In other words, even if hot water adheres to the operation surface on which the touch operation of the bath operation device is attached and the capacitance value changes to the set judgment value or more, the attached hot water immediately flows down. In view of the fact that the change time changing beyond the set judgment value does not exceed the misjudgment avoidance time, the change time during which the capacitance value is changing beyond the set judgment value is equal to or greater than the misjudgment avoidance time. For the touch switch, it may be determined that there is a touch operation.
In addition, although the 1st form and the 2nd form can be applied to each separately, it is also conceivable to apply the form in combination.

However, the first mode and the second mode for avoiding misjudgment deteriorate operability, and improvement is desired.
That is, for example, when the user performs a touch operation with the finger along the operation surface, in addition to the capacitance value of the operation target touch switch positioned corresponding to the fingertip of the finger, the finger away from the fingertip of the finger The capacitance value of the touch switch located corresponding to the part also changes, and in addition to the touch switch to be operated, the capacitance value of the adjacent touch switch may change more than the set judgment value. In such a case, in the first form, it is determined that there is no touch operation.

  Incidentally, since the capacitance type touch sensor changes the capacitance value when a finger approaches even if no touch operation is performed, as described above, the capacitance type touch sensor is adjacent to the operation target touch switch. There is a possibility that the capacitance value of the touch switch may change more than the set determination value. In such a case, it is determined that there is no touch operation in the first mode.

  However, when the touch operation of the user makes a touch operation on the adjacent touch switch in addition to the touch switch to be operated, that is, the touch operation on a plurality of touch switches is performed by the user's touch operation. In such a case, it is desirable to process the touch operation as an effective touch operation. However, in the case of the first embodiment, since it is determined that there is no touch operation, the touch operation is determined as an effective touch operation. It cannot be processed.

  In addition, when there are touch operations for a plurality of touch switches, for example, it is informed by voice guidance or a display screen that it is not an appropriate touch operation, and an appropriate touch operation is prompted, When there is a touch switch to be prioritized among multiple touch switches, the touch operation is effective even when there are touch operations for multiple touch switches, such as enabling only the touch operation of the touch switch. Although it is desired to process as a touch operation, in the case of the first form, since it is determined that there is no touch operation, the touch operation cannot be processed as an effective touch operation. There was a risk that it would decrease.

  By the way, as an operation mode in which the capacitance values of a plurality of adjacent touch switches change to a setting determination value or more, in addition to a case where the user performs a touch operation with a finger along the operation surface, for example, adjacent A case where a touch operation is performed with a fingertip at a corresponding position between two touch switches is conceivable.

  In the second embodiment, if the time for performing the touch operation by the user is short, it is erroneously determined that the touch operation is not performed despite the user's touch operation. The user needs to perform a touch operation over the time for avoiding erroneous determination, and the operability is degraded.

  In other words, the user needs to perform the touch operation over the misjudgment avoidance time, although the user has only to instantaneously touch the touch switch, and the operability is reduced.

  As described above, when the operation determination unit determines the presence / absence of a touch operation for each of the touch switches based on the capacitance value output from each of the plurality of touch switches, the technique of Patent Document 1 is used. When using it and avoiding misjudgment by the adhesion of the hot water at the time of performing a shower bath, operativity falls and improvement was desired.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a bath operating device capable of improving operability while avoiding erroneous determination due to adhesion of hot water.

The bath operation device according to the present invention includes a plurality of capacitance-type touch switches arranged side by side, and a plurality of touch switches based on capacitance values output from the plurality of touch switches. Operation determining means for determining the presence or absence of the touch operation is provided, the first characteristic configuration is
A basic determination mode in which the operation determination means determines whether or not the touch operation is performed based on a basic determination condition determined under a condition that a change in the capacitance value of the touch switch does not occur due to water adhesion; An erroneous determination avoidance mode for determining presence or absence of the touch operation based on a determination condition for avoiding erroneous determination determined to avoid erroneous determination when the change in the capacitance value of the touch switch occurs due to water adhesion; It is configured to be freely switchable ,
The operation determining means determines whether a shower bath prediction condition for predicting a shower bath in a bathroom is satisfied, and when the shower bath prediction condition is not satisfied, the basic determination mode is set, When the shower bath prediction condition is satisfied, the misjudgment avoidance mode is set.

  That is, since the fact that the hot water adheres to the operation surface for performing the touch operation of the bath operation device can be limited to when taking a shower in the bathroom, when taking a shower in the bathroom, Switch to the erroneous determination avoidance mode, and switch to the basic determination mode at other times.

In the basic determination mode, since it is not necessary to avoid erroneous determination due to adhesion of hot and cold water, the basic determination condition is determined under the condition that the change in the capacitance value of the touch switch is a user's touch operation. Will be able to.
That is, the basic determination condition is determined to be that there is a touch operation, for example, among touch switches whose capacitance value has changed to a setting determination value or more that determines that there is a touch operation. It is possible to determine the touch switch on which the user's touch operation has been performed, and accurately determine that the touch operation is present.

Further, in the erroneous determination avoidance mode, erroneous determination avoidance determination conditions can be set under conditions that allow an erroneous determination due to the attachment of hot water to be appropriately avoided.
That is, the determination condition for erroneous determination avoidance is determined that, for example, when there are a plurality of touch switches whose capacitance value is changed to a setting determination value or more, there is no touch operation for all of the plurality of touch switches. If there is one touch switch whose capacitance value is changed to a setting determination value or more among the plurality of touch switches, the condition is determined to determine that there is a touch operation for the touch switch. And erroneous determination due to adhesion of hot and cold water can be avoided appropriately.

  In other words, since the basic judgment mode and the misjudgment avoidance mode are switched, the basic judgment condition is set to a condition that allows the user's touch operation to be satisfactorily determined, and the user's touch operation is appropriately performed. The determination is made so that the erroneous determination avoidance determination condition is set to a condition that does not cause an erroneous determination even if hot water adheres, and the erroneous determination due to the adhesion of hot water is appropriately avoided.

  Therefore, in the misjudgment avoidance mode, it is necessary to avoid the occurrence of misjudgment, and it is unavoidable that the operability is reduced. The operability can be improved, and as a whole, the operability can be improved while avoiding erroneous determination due to adhesion of hot water.

  In short, according to the first characteristic configuration of the present invention, it is possible to provide a bath operating device capable of improving operability while avoiding erroneous determination due to adhesion of hot water.

In addition , when the shower bath prediction condition for predicting a shower bath in the bathroom is not satisfied, the operation determination means automatically switches to the basic determination mode, and the shower bath prediction condition for predicting the shower bath in the bathroom is If it is satisfied, the operation determination means automatically switches to the erroneous determination avoidance mode.

  As described above, since the operation determination unit automatically switches between the basic determination mode and the erroneous determination avoidance mode, a special operation for switching the operation determination unit between the basic determination mode and the erroneous determination avoidance mode is required. None, it is possible to improve operability while avoiding erroneous determination due to adhesion of hot and cold water.

In short, according to the first characterizing feature of the present invention, in addition to the above Symbol operation for effect, without requiring a special operation, improve the operability while avoiding erroneous determination due to hot water adhesion .

The bath operation device according to the present invention includes a plurality of capacitance-type touch switches arranged side by side, and a plurality of touch switches based on capacitance values output from the plurality of touch switches. Operation determining means for determining the presence or absence of the touch operation is provided, the second characteristic configuration is
A basic determination mode in which the operation determination means determines whether or not the touch operation is performed based on a basic determination condition determined under a condition that a change in the capacitance value of the touch switch does not occur due to water adhesion; An erroneous determination avoidance mode for determining presence or absence of the touch operation based on a determination condition for avoiding erroneous determination determined to avoid erroneous determination when the change in the capacitance value of the touch switch occurs due to water adhesion; It is configured to be freely switchable,
Among the plurality of touch switches, the basic determination condition is that there is the touch operation for the touch switch in which the capacitance value changes to a setting determination value that is determined to be the presence of the touch operation. It is a condition to judge,
When the determination condition for avoiding erroneous determination is that there are a plurality of touch switches in which the capacitance value changes to the set determination value or more, there is no touch operation for all of the plurality of touch switches. And when there is only one touch switch in which the capacitance value changes more than the set determination value among the plurality of touch switches, the one touch switch It is characterized in that it is a condition for determining that the touch operation is present.

That is, since the fact that the hot water adheres to the operation surface for performing the touch operation of the bath operation device can be limited to when taking a shower in the bathroom, when taking a shower in the bathroom, Switch to the erroneous determination avoidance mode, and switch to the basic determination mode at other times.
In the basic determination mode, since it is not necessary to avoid erroneous determination due to adhesion of hot and cold water, the basic determination condition is determined under the condition that the change in the capacitance value of the touch switch is a user's touch operation. Will be able to.
That is, the basic determination condition is determined to be that there is a touch operation, for example, among touch switches whose capacitance value has changed to a setting determination value or more that determines that there is a touch operation. It is possible to determine the touch switch on which the user's touch operation has been performed, and accurately determine that the touch operation is present.
Further, in the erroneous determination avoidance mode, erroneous determination avoidance determination conditions can be set under conditions that allow an erroneous determination due to the attachment of hot water to be appropriately avoided.
That is, the determination condition for erroneous determination avoidance is determined that, for example, when there are a plurality of touch switches whose capacitance value is changed to a setting determination value or more, there is no touch operation for all of the plurality of touch switches. If there is one touch switch whose capacitance value is changed to a setting determination value or more among the plurality of touch switches, the condition is determined to determine that there is a touch operation for the touch switch. And erroneous determination due to adhesion of hot and cold water can be avoided appropriately.
In other words, since the basic judgment mode and the misjudgment avoidance mode are switched, the basic judgment condition is set to a condition that allows the user's touch operation to be satisfactorily determined, and the user's touch operation is appropriately performed. The determination is made so that the erroneous determination avoidance determination condition is set to a condition that does not cause an erroneous determination even if hot water adheres, and the erroneous determination due to the adhesion of hot water is appropriately avoided.
Therefore, in the misjudgment avoidance mode, it is necessary to avoid the occurrence of misjudgment, and it is unavoidable that the operability is reduced. The operability can be improved, and as a whole, the operability can be improved while avoiding erroneous determination due to adhesion of hot water.
In short, according to the second characteristic configuration of the present invention, it is possible to provide a bath operating device capable of improving operability while avoiding erroneous determination due to adhesion of hot water.
In the basic determination mode, it is determined that there is a touch operation on the operation target touch switch based on the basic determination condition by instantaneously touching the operation target touch switch.
Incidentally, even when there are a plurality of touch switches whose capacitance values are changed to the setting determination value or more, it is determined that there is a touch operation for all of the plurality of touch switches.

  On the other hand, in the misjudgment avoidance mode, when there are a plurality of touch switches whose capacitance value is changed to the set judgment value or more, there is a high possibility of adhesion of hot water. It is determined that there is no touch operation for all of the touch switches, and among the plurality of touch switches, there is only one touch switch whose capacitance value changes to a setting determination value or more. Is a touch operation by the user, and it is determined that there is a touch operation for the one touch switch.

  Therefore, in the misjudgment avoidance mode, while accurately avoiding misjudgment due to adhesion to hot water, in the basic judgment mode, by touching the touch switch of the operation target instantaneously, It is accurately determined that there is a touch operation, and it is possible to appropriately improve operability while accurately avoiding erroneous determination due to adhesion of hot water.

In short, according to the second characterizing feature of the present invention, in addition to the above Symbol operation for effect, while avoiding accurately erroneous determination due to hot water adhesion, the bath operating device can be appropriately improved operability Can be provided.

The bath operation device according to the present invention includes a plurality of capacitance-type touch switches arranged side by side, and a plurality of touch switches based on capacitance values output from the plurality of touch switches. Operation determining means for determining the presence or absence of a touch operation is provided, and the third characteristic configuration thereof is:
A basic determination mode in which the operation determination means determines whether or not the touch operation is performed based on a basic determination condition determined under a condition that a change in the capacitance value of the touch switch does not occur due to water adhesion; An erroneous determination avoidance mode for determining presence or absence of the touch operation based on a determination condition for avoiding erroneous determination determined to avoid erroneous determination when the change in the capacitance value of the touch switch occurs due to water adhesion; It is configured to be freely switchable,
Among the plurality of touch switches, the basic determination condition is that there is the touch operation for the touch switch in which the capacitance value changes to a setting determination value that is determined to be the presence of the touch operation. It is a condition to judge,
Regarding the touch switch in which the determination condition for erroneous determination avoidance is a plurality of the touch switches, and the change time in which the capacitance value is changed to the set determination value or more is equal to or longer than the erroneous determination avoidance time. The condition is that the touch operation is determined to be present.

That is, since the fact that the hot water adheres to the operation surface for performing the touch operation of the bath operation device can be limited to when taking a shower in the bathroom, when taking a shower in the bathroom, Switch to the erroneous determination avoidance mode, and switch to the basic determination mode at other times.
In the basic determination mode, since it is not necessary to avoid erroneous determination due to adhesion of hot and cold water, the basic determination condition is determined under the condition that the change in the capacitance value of the touch switch is a user's touch operation. Will be able to.
That is, the basic determination condition is determined to be that there is a touch operation, for example, among touch switches whose capacitance value has changed to a setting determination value or more that determines that there is a touch operation. It is possible to determine the touch switch on which the user's touch operation has been performed, and accurately determine that the touch operation is present.
Further, in the erroneous determination avoidance mode, erroneous determination avoidance determination conditions can be set under conditions that allow an erroneous determination due to the attachment of hot water to be appropriately avoided.
That is, the determination condition for erroneous determination avoidance is determined that, for example, when there are a plurality of touch switches whose capacitance value is changed to a setting determination value or more, there is no touch operation for all of the plurality of touch switches. If there is one touch switch whose capacitance value is changed to a setting determination value or more among the plurality of touch switches, the condition is determined to determine that there is a touch operation for the touch switch. And erroneous determination due to adhesion of hot and cold water can be avoided appropriately.
In other words, since the basic judgment mode and the misjudgment avoidance mode are switched, the basic judgment condition is set to a condition that allows the user's touch operation to be satisfactorily determined, and the user's touch operation is appropriately performed. The determination is made so that the erroneous determination avoidance determination condition is set to a condition that does not cause an erroneous determination even if hot water adheres, and the erroneous determination due to the adhesion of hot water is appropriately avoided.
Therefore, in the misjudgment avoidance mode, it is necessary to avoid the occurrence of misjudgment, and it is unavoidable that the operability is reduced. The operability can be improved, and as a whole, the operability can be improved while avoiding erroneous determination due to adhesion of hot water.
In short, according to the third characteristic configuration of the present invention, it is possible to provide a bath operating device capable of improving operability while avoiding erroneous determination due to adhesion of hot water.
In the basic determination mode, it is determined that there is a touch operation on the operation target touch switch based on the basic determination condition by instantaneously touching the operation target touch switch.
Incidentally, even when there are a plurality of touch switches whose capacitance values are changed to the setting determination value or more, it is determined that there is a touch operation for all of the plurality of touch switches.

On the other hand, in the misjudgment avoidance mode, the touch switch to be operated is touched based on the misjudgment avoidance judgment condition by touching the touch switch to be manipulated for more than the misjudgment avoidance time. It is determined that there is an operation.
In other words, even if hot water is attached to the touch switch by the shower bath, the attached hot water will immediately flow down, so the change time when the capacitance value changes to the set judgment value or more is more than the misjudgment avoidance time Therefore, it is possible to avoid misjudgment due to adhesion of hot and cold water, and by touching the operation target touch switch for more than the time for avoiding misjudgment, it is determined that there is touch operation on the touch switch to be operated. It is done.

  Therefore, in the misjudgment avoidance mode, while accurately avoiding misjudgment due to adhesion to hot water, in the basic judgment mode, by touching the touch switch of the operation target instantaneously, It is accurately determined that there is a touch operation, and it is possible to appropriately improve operability while accurately avoiding erroneous determination due to adhesion of hot water.

In short, according to the third characterizing feature of the present invention, in addition to the above Symbol operation for effect, while avoiding accurately erroneous determination due to hot water adhesion, the bath operating device can be appropriately improved operability Can be provided.

In addition to the second or third characteristic configuration described above, the fourth characteristic configuration of the bath operating device of the present invention includes:
The operation determining means determines whether a shower bath prediction condition for predicting a shower bath in a bathroom is satisfied, and when the shower bath prediction condition is not satisfied, the basic determination mode is set, When the shower bath prediction condition is satisfied, the misjudgment avoidance mode is set.
That is, when the shower bath prediction condition for predicting a shower bath in the bathroom is not satisfied, the operation determination means automatically switches to the basic determination mode, and the shower bath prediction condition for predicting the shower bath in the bathroom is If it is satisfied, the operation determination means automatically switches to the erroneous determination avoidance mode.
As described above, since the operation determination unit automatically switches between the basic determination mode and the erroneous determination avoidance mode, a special operation for switching the operation determination unit between the basic determination mode and the erroneous determination avoidance mode is required. None, it is possible to improve operability while avoiding erroneous determination due to adhesion of hot and cold water.
In short, according to the fourth characteristic configuration of the present invention, in addition to the operational effects of the second or third characteristic configuration, the operability can be improved while avoiding erroneous determination due to adhesion of hot water without requiring a special operation. Improvements can be made.
The fifth characteristic feature of the bath operating device of the present invention, in addition to the configuration of the first or fourth feature,
If the hot water supply amount per unit time of the water heater for supplying hot water to the bathroom is equal to or greater than a set threshold, the operation determining means determines that the shower bath prediction condition for predicting the shower bath in the bathroom is satisfied. When the shower bath prediction condition is satisfied, the erroneous determination avoidance mode is set, and when the shower bath prediction condition is not satisfied, the basic determination mode is set. And

  That is, when the amount of hot water supply per unit time of the water heater for supplying hot water to the bathroom is equal to or higher than the set threshold value, it is highly possible that the shower bath is being performed. If it is determined and the mode is switched to the erroneous determination avoidance mode, and the amount of hot water supply per unit time of the water heater is less than the set threshold, it is unlikely that the shower bath is being performed. It is determined that the prediction condition is not satisfied, and the mode is switched to the basic determination mode.

  Therefore, it is possible to switch between the basic determination mode and the erroneous determination avoidance mode with a simple configuration that determines whether or not the amount of hot water supply per unit time of the water heater is equal to or greater than the set threshold value.

In short, according to the fifth aspect of the present invention, in addition to the effects by the first or fourth feature configuration, with a simple construction, it can be switched to the determined avoidance mode erroneously fundamental determination mode A bath operating device can be provided.

The sixth characterizing feature of the bath operating device of the present invention, in addition to the configuration of the first or fourth feature,
A water heater that supplies hot water to the bathroom is configured to perform an automatic hot water operation that supplies hot water of a set target temperature to a bathtub to a set target hot water amount or a target set water level,
When the operation determining means supplies hot water before the set time elapses after the water heater has performed the automatic hot water operation, a shower bath prediction condition for predicting a shower bath in the bathroom is satisfied. When the shower bath prediction condition is satisfied, the erroneous determination avoidance mode is set. When the shower bath prediction condition is not satisfied, the basic determination mode is set. It is characterized by that.

  That is, when the hot water heater supplies hot water after execution of the automatic hot water operation until the set time elapses, there is a high possibility that the shower bath is being performed. Is switched to the misjudgment avoidance mode, even if the set time elapses after execution of the automatic hot water operation, or if the hot water heater is not hot or If the elapsed time after the operation is out of the set time, it is unlikely that the shower bath is being performed.Therefore, the operation determination means determines that the shower bath prediction condition is not satisfied, and the basic determination is made. Switch to mode.

And, when hot water is supplied between the time when the water heater performs the automatic hot water operation and the set time elapses, the possibility of shower bathing is very high, so the basic judgment mode and the erroneous judgment avoidance mode Can be switched appropriately.
Incidentally, the set time after the execution of the automatic hot water operation is preferably set to about 15 to 60 minutes, for example.

In short, according to the sixth characterizing feature of the present invention, in addition to the effects by the first or fourth feature configuration, the bath operating device capable of appropriately switching between decision avoidance mode erroneously fundamental determination mode Can be provided.

Seventh characterizing feature of the bath operating device of the present invention, in addition to the configuration of the first or fourth feature,
The main remote controller and bath remote controller for the hot water heater that supplies hot water to the bathroom and other locations are configured to switch the priority state for setting the target hot water temperature,
The bath remote controller is equipped with a plurality of the touch switches and the operation determination means,
When the operation determination unit is switched to the bath remote controller and the priority state is switched, when the water heater supplies hot water, a shower bath prediction condition for predicting a shower bath in the bathroom is satisfied. When the shower bath prediction condition is satisfied, the erroneous determination avoidance mode is set. When the shower bath prediction condition is not satisfied, the basic determination mode is set. It is characterized by that.

  In other words, when the priority is switched to the bath remote controller between the main remote controller installed in the kitchen or the like and the bath remote controller installed in the bathroom, a shower bath is used when the water heater supplies hot water. Since it is highly likely that the operation has been performed, the operation determination means switches to the erroneous determination avoidance mode, and even if the priority state is switched to the bath remote control, the hot water heater does not supply hot water or has priority over the main remote control. When the state is switched, the possibility that the shower bath is being performed is low, so the operation determination means determines that the shower bath prediction condition is not satisfied and switches to the basic determination mode. Become.

  And when the bath remote control is switched to the priority state and the water heater supplies hot water, the possibility of shower bathing is quite high, so switch between the basic judgment mode and the erroneous judgment avoidance mode appropriately. Can do.

In short, according to the seventh characterizing feature of the present invention, in addition to the effects by the first or fourth feature configuration, the bath operating device capable of appropriately switching between decision avoidance mode erroneously fundamental determination mode Can be provided.

It is a condition to be judged.

Specifically, the operation control unit C is configured to communicate the detected flow rate of the water amount sensor 14 when performing general hot water supply to the bath remote controller R2.
When the detected flow rate of the water amount sensor 14 is equal to or greater than the set threshold, the main control unit 70 determines that the shower bath prediction condition is satisfied.

The second condition is a condition for determining that the shower bath prediction condition is satisfied when the hot water heater G supplies hot water after execution of the automatic hot water operation until the set time elapses.
For example, the set time is set to an appropriate time between 15 and 60 minutes.

(Summary of embodiment)
As described above, the main control unit 70 switches between the basic determination mode and the erroneous determination avoidance mode, and the basic determination condition is set to a condition that allows the user to properly determine the touch operation. Since the judgment avoidance judgment condition is set to a condition that does not cause erroneous judgment even when hot water adheres, in the misjudgment avoidance mode, it is necessary to avoid occurrence of misjudgment. However, in the basic judgment mode, it is not subject to the restriction to avoid misjudgment due to hot water adhering, so the operability can be improved. The operability can be improved while avoiding the above.

  In addition, when the shower bath prediction condition for predicting the shower bath in the bathroom D is not satisfied, the main control unit 70 automatically switches to the basic determination mode, and the shower in which the shower bath in the bathroom D is predicted. When the bath prediction condition is satisfied, the mode is automatically switched to the misjudgment avoidance mode. The operability can be improved while avoiding the determination.

[Second Embodiment]

W is a condition for determining that there is a touch operation.
Incidentally, the setting determination value is set according to the sensitivity of the touch switch W.

On the other hand, the misjudgment avoidance determination condition in the misjudgment avoidance mode has a change time in which the capacitance value changes to the set determination value or more among the plurality of touch switches W or more than the misdetermination avoidance time The touch switch W is a condition for determining that there is a touch operation.
Incidentally, the erroneous determination avoidance time is set to about 500 to 700 mmS, for example.

  In the second embodiment, even if hot water adheres to the touch switch W due to the shower bath in the erroneous determination avoidance mode, the attached hot water immediately flows down, so that the capacitance value changes to the set determination value or more. Since the change time is not longer than the misjudgment avoidance time, it is possible to avoid the misjudgment caused by the hot water adhering while touching the touch switch W to be manipulated for more than the misjudgment avoidance time. The touch switch W is determined to have a touch operation.

  Accordingly, in the misjudgment avoidance mode, while the misjudgment due to adhesion to hot water is accurately avoided, in the basic judgment mode, the touch switch W to be operated is instantaneously touched to operate the touch switch W to be operated. Therefore, it is accurately determined that there is a touch operation, and it is possible to appropriately improve operability while accurately avoiding erroneous determination due to adhesion of hot water.
