FIG. 2 is a block diagram schematically showing the washroom space system and washstand according to the first embodiment.
As shown in FIG. 2, the washstand 10 includes a human body detection sensor 40 and a control section 42.

The human body detection sensor 40 detects a human body. The human body detection sensor 40 detects, for example, a hand extended to the washbasin 20. In other words, the human body detection sensor 40 makes it possible to detect a hand held out to the washbasin 20 by detecting an object close to the water spouting part 22a. In this case, the human body detection sensor 40 is, for example, a sensor using infrared light. The human body detection sensor 40 is connected to the control section 42 and inputs detection information representing the detection result of the human body to the control section 42 .

The control unit 42 is configured to be able to communicate with the air conditioner 12, which is a washroom space device installed in the washroom space WS. Communication between the control unit 42 and the air conditioner 12 may be wired or wireless. The control unit 42 can transmit a control signal to the air conditioner 12. The control unit 42 can control the operation of the air conditioner 12 by transmitting a control signal to the air conditioner 12. Further, the control unit 42 controls the operation of the internal devices provided in the bathroom vanity 10 by, for example, transmitting a control signal to the internal devices. Note that when transmitting a control signal to the air conditioner 12 by wireless communication, the control signal may be transmitted from the control unit 42 via a transmitting antenna (not shown) built in the bathroom vanity.

The washstand 10 further includes a power supply section 44 and a switching valve 46. The power supply section 44 has a power plug 44a. In other words, the power plug 44a is an outlet plug. The power supply section 44 is connected to a commercial power source or the like via a power plug 44a. The power supply unit 44 converts AC power supplied from a commercial power source into predetermined power, and supplies the same to each part of the bathroom vanity 10 . The power supply unit 44 is, for example, a DC/AC converter that converts AC power into DC power and supplies the DC power. Each section, such as the human body detection sensor 40, the control section 42, the switching valve 46, and the lighting device 28, operates in accordance with the supply of power from the power supply section 44.

The switching valve 46 switches between spouting water from the water spouting section 22a of the faucet device 22 and stopping the water spouting. The switching valve 46 is connected to the control unit 42 and switches between spouting water and stopping water spouting based on the control of the control unit 42 . The switching valve 46 is, for example, a solenoid valve. However, the switching valve 46 is not limited to an electromagnetic valve, and may be any member capable of switching between spouting water and stopping water spouting based on the control of the control unit 42.

The human body detection sensor 40, the control unit 42, the power supply unit 44, and the switching valve 46 are provided in the faucet device 22, for example. The human body detection sensor 40, the control section 42, the power supply section 44, and the switching valve 46 are provided, for example, in the shelf section 22b of the faucet device 22. However, these arrangements are not limited to the faucet device 22, and may be placed at any position on the washstand 10. The human body detection sensor 40, the control unit 42, the power supply unit 44, and the switching valve 46 may be provided inside the support base 24, inside the mirror cabinet 26, etc., for example.

The control unit 42 determines whether the hand is detected or not based on the detection information from the human body detection sensor 40, and operates the switching valve 46 in response to the switch from the non-detection state to the detection state. Water is automatically spouted from the water spouting part 22a. Then, the control unit 42 automatically stops water spouting from the water spouting unit 22a by stopping the operation of the switching valve 46 in response to the switch from the hand detection state to the non-detection state. That is, in this example, the faucet device 22 is a so-called automatic faucet.

The control unit 42 controls the operation of the switching valve 46 based on the detection information input from the human body detection sensor 40. In this way, the control unit 42 controls the operation of the internal devices provided in the bathroom vanity 10 based on the detection information input from the human body detection sensor 40. The control unit 42 may control turning on and off of the lighting device 28 based on detection information input from the human body detection sensor 40, for example. More specifically, the control unit 42 turns on the lighting device 28 in response to switching from the hand non-detection state to the detection state, and turns on the lighting device 28 in response to the hand switching from the hand detection state to the non-detection state. 28 may be turned off.

The air conditioner 12 has a power plug 12a. In other words, the power plug 12a is an outlet plug. The air conditioner 12 is connected to a commercial power source or the like via a power plug 12a. The air conditioner 12 converts AC power supplied from a commercial power source into predetermined power and supplies it to each part of the air conditioner 12 .

The air conditioner 12 can operate independently based on the power supplied via the power plug 12a without depending on a control signal from the control unit 42 of the washstand 10. The air conditioner 12 has, for example, an operation section (remote controller) not shown, and operates based on the operation of the operation section. The air conditioner 12 switches between starting and stopping its operation in accordance with the operation of the operating unit. In addition, the air conditioner 12 switches various settings, such as switching between operating modes such as cooling operation and heating operation, or switching the set temperature, in accordance with the operation of the operating unit.

Moreover, the air conditioner 12 can execute operations according to the control signal by receiving a control signal from the control unit 42 of the bathroom vanity 10 .

The control unit 42 of the bathroom vanity 10 can cause the air conditioner 12 to perform an operation according to the detection information by transmitting a control signal based on the detection information of the human body detection sensor 40 to the air conditioner 12.

For example, the control unit 42 transmits a control signal to the air conditioner 12 in response to switching from the hand non-detection state to the detection state, thereby causing the air conditioner 12 to start operating, and changing from the hand detection state to the non-detection state. By transmitting a control signal to the air conditioner 12 in response to switching to the detection state, the air conditioner 12 is caused to stop operating.

FIG. 3 is a flowchart schematically representing an example of the operation of the washroom space system according to the first embodiment.
As shown in FIG. 3, in the washroom space system 2, first, the control unit 42 of the washstand 10 changes the hand (human body) from the non-detection state to the detection state based on the detection information from the human body detection sensor 40. It is determined whether the switch has been made (step S101 in FIG. 3). The control unit 42 repeatedly determines whether the state has changed from the non-detection state to the detection state until the state is switched from the non-detection state to the detection state.

When the control unit 42 determines that the state has changed from the non-detection state to the detection state, it transmits a control signal to the air conditioner 12 (step S102 in FIG. 3).

The air conditioner 12 operates, for example, in a standby mode in which air conditioning is not performed, and determines whether or not a control signal has been received (step S201 in FIG. 3). Then, the air conditioner 12 starts operating in response to receiving the control signal from the bathroom vanity 10 (step S202 in FIG. 3). In other words, the air conditioner 12 switches from standby mode to a predetermined operating mode in response to receiving the control signal. The predetermined operation mode is, for example, a preset operation mode such as a cooling operation mode or a heating operation mode.

The control signal transmitted from the control unit 42 to the air conditioner 12 is, for example, a signal for switching the air conditioner 12 from a stopped state to an operating state. Thereby, the operation can be started without the need for determination on the air conditioner 12 side. The control signal transmitted from the control unit 42 to the air conditioner 12 is, for example, a signal representing the detection of a hand, and the air conditioner 12 side determines the switching from non-detection to detection, thereby causing the air conditioner 12 to start operation. It's okay. In this case, there is no need to generate a control signal corresponding to the air conditioner 12 on the control section 42 side, and the configuration of the control section 42 can be simplified. In addition, the start of operation of the air conditioner 12 is not limited to switching from standby mode to operation mode, and for example, the air conditioner 12 can be started by supplying power to the air conditioner 12 by inputting a control signal. The operation may be started.

After transmitting the control signal, the control unit 42 of the bathroom vanity 10 determines whether the hand detection state has been switched to the non-detection state based on the detection information from the human body detection sensor 40 (step in FIG. 3). S103). The control unit 42 repeatedly determines whether the detection state has been switched to the non-detection state until the detection state is switched to the non-detection state.

When the control unit 42 determines that the detection state has switched to the non-detection state, it transmits a control signal to the air conditioner 12 (step S104 in FIG. 3).

After the air conditioner 12 starts operating, it determines whether a control signal has been received (step S203 in FIG. 3). The air conditioner 12 then stops operating in response to receiving the control signal from the bathroom vanity 10 (step S204 in FIG. 3). In other words, the air conditioner 12 returns from the operating mode to the standby mode in response to receiving the control signal.

As described above, according to the washroom space system 2 and the washstand 10 according to the present embodiment, a control signal is sent to the air conditioner 12 ( By transmitting the detected information to the washroom space equipment), it is possible to cause the air conditioner 12 to perform an operation according to the detected information. For example, the air conditioner 12 can be caused to start operating and stop operating. Thereby, it is not necessary to provide the human body detection sensor 40 in the air conditioner 12, and the cost of the air conditioner 12 can be suppressed even when controlling appropriate to the usage situation.

Further, in the washstand 10, the human body detection sensor 40 detects a hand extended to the washbowl 20. This makes it possible to determine the presence or absence of a human body focusing on the act of washing. For example, it is possible to detect a human body that has just entered the washroom space WS or a human body that has just passed through the washroom space WS, and to prevent the air conditioner 12 from operating unnecessarily. Therefore, it is possible to appropriately control the air conditioner 12 by focusing only on the person using the bathroom vanity 10, and it is possible to further improve convenience for the user. For example, unnecessary operations of the air conditioner 12 can be further suppressed, and running costs can be further suppressed.

When a hand extended into the washbowl 20 is detected, the user stops washing his hands and no detection is detected, and then the user starts washing his hands again, which turns the air conditioner 12 on and off (starts operation). There is a possibility that the process (and the suspension of operation) may be repeated. Therefore, when the hand detection state is switched to the non-detection state, the operation of the air conditioner 12 may be stopped by transmitting a control signal in response to the non-detection state continuing for a predetermined period of time. This can prevent the air conditioner 12 from repeatedly turning on and off at short intervals. It is possible to more appropriately detect a user's suspension of use and further improve convenience.

Note that the human body detection sensor 40 is not limited to a sensor that detects a hand extended to the washbasin 20. The human body detection sensor 40 may be, for example, a sensor that detects a human body entering the washroom space WS, a sensor that detects a human body approaching the washbowl 20, or the like. In this case, the human body detection sensor 40 can be, for example, a distance measurement sensor using infrared light, a pyroelectric sensor, or a radio wave sensor such as a microwave sensor. The human body detection sensor 40 may be any sensor that can appropriately detect a human body such as a user approaching the washstand 10.

The air conditioner 12, air purifier 14, and dehumidifier 16 can each perform the following operations.

In this case, the control unit 42 generates a plurality of control signals corresponding to each of the air conditioner 12, the air cleaner 14, and the dehumidifier 16, and Send to each. Thereby, each operation of the air conditioner 12, the air cleaner 14, and the dehumidifier 16 can be appropriately controlled.

The control unit 42 may transmit the same control signal to each of the air conditioner 12, air purifier 14, and dehumidifier 16, for example. For example, a signal representing the detection of a human body is transmitted to each of the air conditioner 12, air purifier 14, and dehumidifier 16, and each of the air conditioner 12, air purifier 14, and dehumidifier 16 responds to the detection of the human body. An action may be executed. In this case, the configuration of the control section 42 can be simplified. Further, there is no need to store information on each device in the control unit 42 in advance, and it is possible to easily cope with the addition of washroom space devices.

For example, the control unit 42 controls the air conditioner 12 by transmitting a control signal to each of the air conditioner 12, the air purifier 14, and the dehumidifier 16 in response to the change from the non-detection state to the detection state of the human body. , the air purifier 14, and the dehumidifier 16, and in response to the switch from the human body detection state to the non-detection state, control signals are sent to the air conditioner 12, the air purifier 14, and the dehumidifier 16. By transmitting the information to each of the air conditioners 12, the air purifier 14, and the dehumidifier 16, the operations of the air conditioners 12, air purifiers 14, and dehumidifiers 16 are stopped.

In this way, in the washroom space system 2a, by transmitting control signals to a plurality of washroom space devices based on the detection information of the human body detection sensor 40 provided in the washstand 10a, a plurality of operations can be performed according to the detection information. It can be carried out in the washroom space equipment. For example, a plurality of washroom space devices can be caused to start and stop operating. Thereby, it is not necessary to provide the human body detection sensor 40 in each of the plurality of washroom space devices, and the cost of the plurality of washroom space devices can be suppressed even when controlling appropriate for the usage situation.

Therefore, even if each of the plurality of washroom space devices is configured to perform control appropriate to the usage situation in order to create a comfortable washroom space WS, the human body detection sensor 40 or the like is installed in each of the plurality of washroom space devices. Compared to the case where the system is provided, the cost burden on the user can be reduced. To provide washstands 10 and 10a that can reduce the cost burden on users when controlling a plurality of washroom space devices in a manner appropriate to the user's usage conditions, aiming to improve user convenience. be able to.

Note that the washroom space equipment is not limited to the air conditioner 12, the air purifier 14, and the dehumidifier 16. The washroom space equipment may be, for example, an electric fan, a dehumidifier, an electric water heater, audio equipment, video equipment, or an aroma diffuser. For example, an electric water heater is installed within the support base 24 of the bathroom vanity 10. In this way, the washroom space equipment is not limited to being provided separately from the washstand 10a, and may be used by being incorporated into the washstand 10a. Electric power for the bathroom space equipment may be supplied from the bathroom vanity 10a, for example, via a service outlet provided on the bathroom vanity 10a. The washroom space equipment is installed and used in the washroom space WS, has a power plug separate from the power supply of the washstand, and is any device that can operate independently based on the power supplied via the power plug. Any equipment is fine.

(Second embodiment)
FIG. 5 is a block diagram schematically showing a washroom space system and a washstand according to the second embodiment.
As shown in FIG. 5, in the washroom space system 2b, the washstand 10b further includes a room temperature sensor 50 (environmental state measurement sensor).

Room temperature sensor 50 measures the room temperature in washroom space WS as the environmental state of washroom space WS. Room temperature sensor 50 is connected to control section 42 . The room temperature sensor 50 inputs room temperature measurement information to the control unit 42 .

The control unit 42 transmits a control signal to the air conditioner 12 based on the detection information of the human body detection sensor 40 and the measurement information of the room temperature sensor 50.

FIG. 6 is a flowchart schematically showing an example of the operation of the washroom space system according to the second embodiment.
In FIG. 6, an example of the operation of the washroom space system 2b will be described using a case where the air conditioner 12 is set to the cooling operation mode.
As shown in FIG. 6, in the washroom space system 2b, first, the control unit 42 of the washstand 10b changes the hand (human body) from the non-detection state to the detection state based on the detection information from the human body detection sensor 40. It is determined whether the switch has been made (step S111 in FIG. 6). The control unit 42 repeatedly determines whether the state has changed from the non-detection state to the detection state until the state is switched from the non-detection state to the detection state.

When the control unit 42 determines that the non-detection state has been switched to the detection state, the control unit 42 subsequently determines whether the room temperature of the washroom space WS is equal to or higher than a predetermined temperature based on the measurement information from the room temperature sensor 50 (step in FIG. 6). S112).

When the control unit 42 determines that the room temperature of the washroom space WS is equal to or higher than the predetermined temperature, the control unit 42 transmits a control signal to the air conditioner 12 (step S113 in FIG. 6). As a result, the air conditioner 12 starts operating in the cooling operation mode, and cooling of the washroom space WS starts in response to the detection by the human body detection sensor 40. Note that steps S114, S115, and steps S211 to S214 in FIG. 6 are substantially the same as steps S103, S104, and steps S201 to S204 described with reference to FIG. 3, so a detailed explanation will be omitted.

On the other hand, when the control unit 42 determines that the room temperature of the washroom space WS is lower than the predetermined temperature, the control unit 42 does not transmit the control signal to the air conditioner 12. Thereby, when the room temperature of the washroom space WS is low, it is possible to prevent the air conditioner 12 from operating in the cooling operation mode unnecessarily.

For example, when the air conditioner 12 is set to the heating operation mode, it may be determined in step S112 of FIG. 6 whether the room temperature of the washroom space WS is below a predetermined temperature. When it is determined that the room temperature of the washroom space WS is higher than a predetermined temperature, the control signal is not transmitted to the air conditioner 12. Thereby, when the room temperature of the washroom space WS is high, it is possible to prevent the air conditioner 12 from operating in the heating mode unnecessarily.

In this manner, in the bathroom vanity 10b, if the measurement information satisfies a predetermined condition, the control unit 42 transmits a control signal to the air conditioner 12 in response to the detection of a human body based on the detection information, and performs the measurement. If the information does not meet the predetermined conditions, no control signal is transmitted to the air conditioner 12 even if a human body is detected based on the detection information.

In this washroom space system 2b and washstand 10b, the control unit 42 transmits a control signal to the air conditioner 12 based on the detection information of the human body detection sensor 40 and the measurement information of the room temperature sensor 50, thereby controlling the washroom space WS. More suitable control can be performed depending on the environmental conditions. For example, unnecessary operations of the air conditioner 12 can be suppressed, unnecessary power consumption caused by unnecessary operations can be suppressed, and running costs can also be suppressed.

Furthermore, depending on the environmental condition of the washroom space WS, by controlling the air conditioner 12 so as not to operate even if a human body is detected, it is possible to perform control more suited to the usage situation, further improving user convenience. be able to. For example, running costs can be further reduced.

Note that in this example, the room temperature sensor 50 is shown as an example of an environmental state measuring sensor that measures the environmental state of the washroom space WS, but the environmental state measuring sensor is not limited to the room temperature sensor 50.

For example, when the washroom space equipment is an air purifier, a sensor that measures the air cleanliness of the washroom space WS as an environmental state is set as an environmental state measurement sensor, and when the air cleanliness is less than a predetermined value, a control signal is sent. You may choose not to send it.

For example, if the washroom space equipment is a dehumidifier or humidifier, a humidity sensor that measures the humidity of the washroom space WS as an environmental state may be used as an environmental state measurement sensor, and control signals may not be transmitted depending on the humidity. good.

In this way, the environmental condition measuring sensor may be any sensor capable of measuring any environmental condition corresponding to the washroom space equipment.

Further, when transmitting the control signal to the washroom space equipment, the control unit 42 may change the content of the control signal based on the measurement information of the environmental state measurement sensor. For example, if the washroom space equipment is an air conditioner, the air volume, operation mode, etc. may be changed depending on the room temperature. For example, if the washroom space device is an air purifier, the suction amount etc. may be changed depending on the air cleanliness. For example, when the washroom space equipment is a dehumidifier or a humidifier, the strength of humidification or dehumidification may be changed depending on the humidity.

FIG. 7 is a flowchart schematically showing an example of the operation of the bathroom vanity according to the second embodiment.
FIG. 7 schematically shows a part of the operation of the washstand 10b. The operation in FIG. 7 is executed after transmitting a control signal based on the detection information to the air conditioner 12 and starting the operation of the air conditioner 12. That is, the operation in FIG. 7 is executed between step S113 and step S114 in FIG. 6.

In addition, in FIG. 7, the operation of the washstand 10b is taken as an example where the air conditioner 12 is set to the cooling operation mode and has two operation modes, operation mode A and operation mode B. An example will be explained. Operation mode A is an operation mode recommended when the room temperature of the washroom space WS is equal to or higher than a predetermined threshold. Operation mode B is an operation mode recommended when the room temperature of the washroom space WS is less than a predetermined threshold value set in advance. The operation mode A is, for example, a strong operation mode in which the air volume is increased. Operation mode B is, for example, a weak operation mode in which the air volume is weakened. The operation modes A and B are not limited to these, and, for example, an operation mode with a low set temperature may be set as operation mode A, an operation mode with a high set temperature may be set as operation mode B, etc.

After transmitting a control signal to start the operation of the air conditioner 12, the control unit 42 of the washstand 10b determines whether the room temperature of the washroom space WS is equal to or higher than a threshold value based on the measurement information from the room temperature sensor 50. Determination is made (step S121 in FIG. 7).

If the control unit 42 determines that it is equal to or greater than the threshold value, then it determines whether the current operation mode of the air conditioner 12 is operation mode B (step S122 in FIG. 7).

If the control unit 42 determines that the operating mode is B, it transmits a control signal to the air conditioner 12 for changing the operating mode of the air conditioner 12 from the operating mode B to the operating mode A (step in FIG. 7). S123). The air conditioner 12 changes the operation mode from operation mode B to operation mode A in response to reception of this control signal. Moreover, when the control unit 42 determines that the operation mode is A, the control unit 42 returns to the room temperature determination in step S121 without transmitting a control signal.

If the control unit 42 determines in step S121 that it is less than the threshold value, then it determines whether the current operation mode of the air conditioner 12 is operation mode A (step S124 in FIG. 7).

If the control unit 42 determines that the operating mode is A, it transmits a control signal to the air conditioner 12 for changing the operating mode of the air conditioner 12 from the operating mode A to the operating mode B (step in FIG. 7). S125). The air conditioner 12 changes the operation mode from operation mode A to operation mode B in response to receiving this control signal. Further, when the control unit 42 determines that the operation mode is B, the control unit 42 returns to the room temperature determination in step S121 without transmitting a control signal.

As described above, in this example, the control unit 42 transmits a control signal based on the detection information to the air conditioner 12, and then transmits a control signal based on the measurement information to the air conditioner 12, thereby controlling the operation according to the measurement information. The air conditioner 12 can be caused to perform the following steps.

In this way, by causing the air conditioner 12 to perform operations according to the measurement information, it is possible to perform control more suited to the usage situation, and it is possible to further improve convenience for the user. For example, unnecessary operations of the air conditioner 12 can be further suppressed, and running costs can be further suppressed.

For example, when the room temperature is relatively high, the air conditioner 12 is operated in the strong operation mode, and when the room temperature is relatively low, the air conditioner 12 is operated in the weak operation mode. Air conditioning can be performed by the air conditioner 12, and the user can use the washroom space WS more comfortably. Further, for example, even when the room temperature is relatively low, it is possible to prevent the air conditioner 12 from continuing to operate in the strong operation mode. Thereby, unnecessary power consumption can be suppressed and running costs can be further suppressed.

Note that the operation according to the measurement information may be appropriately set according to the type of washroom space equipment. For example, when the air conditioner 12 is set to the heating operation mode, it is determined whether the room temperature of the washroom space WS is below a threshold value, and if it is below the threshold value, the air conditioner 12 is caused to execute the strong operation mode, If it is higher than a threshold value, the air conditioner 12 may be caused to execute the weak operation mode.

For example, when the washroom space equipment is an air purifier, it is determined whether the air cleanliness of the washroom space WS is below a threshold value, and if it is below the threshold value, the air purifier is caused to execute the strong operation mode, and The air purifier may be caused to perform a weak operation mode when the temperature is higher than .

For example, when the washroom space equipment is a dehumidifier, it is determined whether the humidity in the washroom space WS is above a threshold value, and when it is above the threshold value, the dehumidifier is caused to execute the strong operation mode, and when it is below the threshold value, the dehumidifier is caused to execute the strong operation mode. The dehumidifier may be set to low operating mode.

For example, if the washroom space equipment is a humidifier, it is determined whether the humidity in the washroom space WS is below a threshold value, and if the humidity is below the threshold value, the humidifier is caused to execute the strong operation mode, and when it is higher than the threshold value, the humidifier is caused to execute the strong operation mode. You may also have the humidifier run in low mode.

(Third embodiment)
FIG. 8 is a block diagram schematically showing a washroom space system and a washstand according to the third embodiment.
As shown in FIG. 8, in the bathroom vanity 10c of the bathroom space system 2c, the control section 42 includes a timer 60, a storage section 62, and a calculation section 64. The timer 60 outputs time information obtained by counting a predetermined time as time information. The storage unit 62 enables storage of detection information of the human body detection sensor 40 and time information of the timer 60. Based on the detection information and time information stored in the storage unit 62, the calculation unit 64 calculates the predicted usage time for the next time the user will use the bathroom vanity 10c. Note that the timer 60, the storage section 62, and the calculation section 64 may be provided in the control section 42, or may be provided as separate members from the control section 42 and connected to the control section 42. Note that a timer 60 that outputs time information representing the time may be used. Furthermore, the timer 60 may be capable of outputting both clock information and time information. The time information may include at least one of time information representing the time of day and clock information that measures a predetermined time. Further, the time information may be obtained from an external device through communication, for example.

In the bathroom vanity 10c, when a human body is detected based on the detection information of the human body detection sensor 40, the control unit 42 acquires time information from the timer 60, associates the detection information with the time information, and stores it in the storage unit 62. to be memorized. For example, the control unit 42 starts the timer 60 (resets the clocking time) at the timing when the detection information and time information are stored in the storage unit 62, thereby controlling the time from the previous human body detection to the next human body detection. A timer 60 is made to measure the time.

The control unit 42 causes the calculation unit 64 to calculate the predicted next usage time based on the detection information and time information stored in the storage unit 62. For example, when one piece of clock information is stored as time information in the storage unit 62, the calculation unit 64 calculates the time of the clock information as the predicted usage time. For example, if the time from the previous human body detection to the previous human body detection is one hour, there is a high possibility that the bathroom vanity 10c will be used one hour later. Therefore, in this case, the calculation unit 64 calculates one hour later as the predicted usage time. Further, when there is a plurality of pieces of timekeeping information stored in the storage unit 62, the calculation unit 64 calculates, for example, the average time of the plurality of pieces of timekeeping information as the predicted usage time.

For example, when one piece of time information is stored as time information in the storage unit 62, the calculation unit 64 calculates the time of the time information as the predicted usage time. For example, if the bathroom vanity 10c is used at 7 a.m., there is a high possibility that the bathroom vanity 10c will be used at 7 a.m. the next day as well. In this case, the calculation unit 64 calculates the next 7 a.m. as the predicted usage time.

When there is a plurality of pieces of time information stored in the storage unit 62, the calculation unit 64 statistically calculates the predicted usage time by, for example, so-called learning control. For example, a plurality of pieces of time information are divided into time zones, and the average time of the plurality of time information is calculated for each time zone. Then, the closest average time in a time period ahead of the current time is calculated as the predicted usage time. Thereby, it is possible to calculate a more appropriate predicted usage time according to the usage frequency of the user. However, the calculation method of the predicted usage time by the calculation unit 64 is based on the detection information and time information stored in the storage unit 62, and appropriately calculates the time when the user is likely to use the bathroom vanity 10c next. Any method that allows calculation may be used.

The control unit 42 causes the calculation unit 64 to calculate the predicted next usage time, and then transmits a control signal to the air conditioner 12 based on the calculated predicted usage time, thereby causing the air conditioner 12 to start operating. Thereby, in the bathroom vanity 10c, the air conditioner 12 can be operated in advance before the user actually starts using the bathroom vanity 10c. For example, the user can use the washstand 10c while the washroom space WS is adjusted to an appropriate room temperature.

FIG. 9 is a flowchart schematically showing an example of the operation of the bathroom vanity according to the third embodiment.
As shown in FIG. 9, in the bathroom vanity 10c, the control unit 42 first causes the calculation unit 64 to calculate the predicted next usage time (step S131 in FIG. 9). The calculation of the predicted usage time by the calculation unit 64 is performed, for example, after transmitting a control signal to the air conditioner 12 and stopping the operation of the air conditioner 12.

After calculating the predicted usage time, the control unit 42 determines whether the predicted usage time has been reached based on the time information of the timer 60 (step S132 in FIG. 9).

If the control unit 42 determines that the expected use time has not yet been reached, it then determines whether the hand (human body) has switched from the non-detection state to the detection state based on the detection information from the human body detection sensor 40. (Step S133 in FIG. 9).

If the control unit 42 determines that the non-detection state remains, the control unit 42 returns to determining whether the predicted usage time has been reached. On the other hand, when the control unit 42 determines that the state has changed from the non-detection state to the detection state, it transmits a control signal to the air conditioner 12 to start the operation of the air conditioner 12 (step S134 in FIG. 9).

Further, when the control unit 42 determines that the non-detection state has switched to the detection state, it transmits a control signal, acquires time information from the timer 60, associates the detection information with the time information, and stores it in the storage unit 62. (Step S135 in FIG. 9).

When a human body is detected, the control unit 42 determines whether or not the detection state has switched to the non-detection state, similarly to the first embodiment, and determines that the detection state has switched to the non-detection state. Accordingly, a control signal is sent to the air conditioner 12 to stop the operation of the air conditioner 12 (steps S136 and S137 in FIG. 9).

If it is determined in step S132 that the predicted use time has been reached, the control unit 42 transmits a control signal to the air conditioner 12 to start the operation of the air conditioner 12 (step S138 in FIG. 9). Thereby, it is possible to predict the user's use of the bathroom vanity 10c and operate the air conditioner 12 in advance.

After transmitting the control signal, the control unit 42 determines whether the hand (human body) has switched from the non-detection state to the detection state based on the detection information from the human body detection sensor 40 (step S139 in FIG. 9). .

When the control unit 42 determines that the state has changed from the non-detection state to the detection state, the control unit 42 associates the detection information with the time information, as in the case where a human body is detected before the predicted usage time is reached (step S133). The information is stored in the storage unit 62, and similar processing is performed thereafter.

When determining that the non-detection state remains, the control unit 42 subsequently determines whether a certain period of time has elapsed from the timing at which the control signal was transmitted to start the operation of the air conditioner 12. (Step S140 in FIG. 9).

When the control unit 42 determines that the certain period of time has not elapsed, the control unit 42 returns to determining whether the non-detection state has been switched to the detection state. On the other hand, when the control unit 42 determines that the certain period of time has elapsed, the control unit 42 stops the operation of the air conditioner 12 by transmitting a control signal to the air conditioner 12. After this, the control unit 42 returns to the process of calculating the predicted usage time, and repeats the same process.

In this manner, in the bathroom vanity 10c, when the control unit 42 detects a human body based on the detection information, the control unit 42 acquires time information, associates the detection information with the time information, and stores the detected information. The air conditioner 12 can be operated in advance by calculating the predicted next usage time based on the time information and transmitting a control signal to the air conditioner 12 based on the predicted usage time. Thereby, the air conditioner 12 can be operated in advance before the user actually uses it, and the convenience for the user can be further improved.

Further, in the bathroom vanity 10c, the control unit 42 sends a control signal to operate the air conditioner 12 in advance, and then sends a control signal to stop the operation when a human body is not detected after a certain period of time has elapsed. It is transmitted to the air conditioner 12. This allows the air conditioner 12 to operate in advance before the user actually uses it, improving user convenience while suppressing unnecessary operations of the air conditioner 12 and reducing running costs more appropriately. Can be suppressed.
