The air conditioner 12 can operate as a single unit based on the electric power supplied through the power plug 12a, regardless of the control signal from the control unit 42 of the vanity 10. The air conditioner 12 has, for example, an operation unit (remote controller) (not shown) and operates based on the operation of the operation unit. The air conditioner 12 switches between starting and stopping the operation according to the operation of the operation unit. Further, the air conditioner 12 switches various settings such as switching of operation modes such as cooling operation and heating operation, or switching of set temperature according to the operation of the operation unit.

Further, the air conditioner 12 can execute an operation according to the control signal by receiving the input of the control signal from the control unit 42 of the vanity 10.

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

For example, the control unit 42 causes the air conditioner 12 to start the operation by transmitting a control signal to the air conditioner 12 in response to switching from the non-detection state of the hand to the detection state, and the control unit 42 is released from the detection state of the hand. By transmitting a control signal to the air conditioner 12 in response to switching to the detection state, the air conditioner 12 stops the operation.

The wireless communication unit 48 transmits a control signal to the air conditioner 12 by wireless communication using infrared rays. The wireless communication unit 48 is connected to the control unit 42.

The wireless communication between the vanity 10 and the air conditioner 12 is not limited to the communication using infrared rays. The wireless communication between the vanity 10 and the air conditioner 12 may be, for example, communication using radio waves. Further, the communication between the vanity 10 and the air conditioner 12 is not limited to wireless communication, but may be wired communication. When transmitting a control signal by wireless communication to the air conditioner 12, the control unit 42 may transmit the control signal via a transmission antenna (not shown) built in the vanity.

FIG. 3 is a side view schematically showing the vanity table according to the first embodiment.
As shown in FIG. 3, the wireless communication unit 48 is provided above the mirror units 26e to 26g of the mirror cabinet 26. The wireless communication unit 48 is provided at the upper end of the mirror cabinet 26, for example.

The wireless communication unit 48 irradiates infrared IR diagonally upward and forward. The "front" is, for example, the direction toward the front side when viewed from the user facing the vanity 10. In other words, it is the direction in which the wall surface (building elevation) on which the vanity 10 is attached faces.

FIG. 4 is a flowchart schematically showing an example of the operation of the wash space system according to the first embodiment.
As shown in FIG. 4, in the washroom space system 2, first, the control unit 42 of the vanity 10 changes from the non-detection state of the hand (human body) to the detection state based on the detection information from the human body detection sensor 40. It is determined whether or not the switch has been made (step S101 in FIG. 4). The control unit 42 repeats the determination of whether or not the non-detection state has been switched to the detection state until the non-detection state is switched 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 transmits a control signal to the air conditioner 12 (step S102 in FIG. 4). Further, when the control unit 42 determines that the non-detection state has been switched to the detection state, the control unit 42 opens the switching valve 46 to start water discharge from the water discharge unit 22a of the faucet device 22.

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. 4). Then, the air conditioner 12 is activated in response to the reception of the control signal from the vanity 10 (step S202 in FIG. 4). In other words, the air conditioner 12 switches from the standby mode to a predetermined operation mode in response to the reception of the control signal. The predetermined operation mode is 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 the stopped state to the operating state. As a result, the air conditioner 12 can be started without the need for determination or the like 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 indicating hand detection, and even if the air conditioner 12 is activated by having the air conditioner 12 determine the switching from non-detection to detection. Good. In this case, it is not necessary for the control unit 42 to generate a control signal corresponding to the air conditioner 12, and the configuration of the control unit 42 can be simplified. Further, the start of operation of the air conditioner 12 is not limited to switching from the standby mode to the operation mode. For example, the air conditioner 12 can be started by supplying electric power to the air conditioner 12 by inputting a control signal. You may want to start it.

After transmitting the control signal, the control unit 42 of the vanity 10 determines whether or not 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 of FIG. 4). S103). The control unit 42 repeats the determination of whether or not 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 been switched to the non-detection state, the control unit 42 transmits a control signal to the air conditioner 12 (step S104 in FIG. 4). Further, when the control unit 42 determines that the detection state has been switched to the non-detection state, the control unit 42 closes the switching valve 46 to stop the water discharge from the water discharge unit 22a of the faucet device 22.

After starting the operation, the air conditioner 12 determines whether or not the control signal has been received (step S203 in FIG. 4). Then, the air conditioner 12 stops operating in response to the reception of the control signal from the vanity 10 (step S204 in FIG. 4). In other words, the air conditioner 12 returns from the operation mode to the standby mode in response to the reception of the control signal.

As described above, according to the washroom system 2 and the washstand 10 according to the present embodiment, when the user enters the washroom WS and uses the washstand 10, the washroom 10 is automatically used. The air conditioner 12 can be activated. As a result, the activation of the air conditioner 12 can be triggered by the use of the vanity 10, and the air conditioner 12 can be used at an unintended timing such as entering the temporary wash space WS for collecting laundry. Startup can be suppressed. Therefore, even when the air conditioner 12 is automatically started, it is possible to suppress the start at an unnecessary timing and improve the usability of the wash space WS. For example, the power consumption required to start the air conditioner 12 at an unnecessary timing can be suppressed, and the running cost can be suppressed.

Further, in the vanity 10, the wireless communication unit 48 is provided above the mirror units 26e to 26g, and irradiates infrared IR obliquely forward and upward. As a result, the infrared IR can be reflected on the ceiling, the control signal can be transmitted over a wide range in the wash space WS, and the control signal can be easily received by the air conditioner 12. As a result, the degree of freedom in the installation position of the air conditioner 12 can be increased.

In the vanity 10a, the infrared IR is reflected by the wash bowl 20 so that the control signal can be transmitted over a wide range in the wash space WS, and the control signal can be easily received by the air conditioner 12. As a result, the degree of freedom in the installation position of the air conditioner 12 can be increased.

As described above, the wireless communication unit 48 may irradiate the infrared IR diagonally upward and forward toward the ceiling, or may irradiate the infrared IR diagonally downward and forward toward the washbasin 20. When irradiating infrared IR diagonally forward and downward toward the wash bowl 20, for example, the infrared light projecting unit for detecting the hand of the human body detection sensor 40 is also used as the infrared light projecting unit for wireless communication. May be good. That is, the human body detection sensor 40 may have the function of the wireless communication unit 48.

FIG. 6 is a block diagram schematically showing a modified example of the vanity according to the first embodiment. As shown in FIG. 6, in the vanity 10b, the control unit 42 has a timer 60 for measuring time. The timer 60 may be provided as a member separate from the control unit 42, and the timekeeping information may be input to the control unit 42.

FIG. 7 is a flowchart schematically showing another operation of the vanity according to the first embodiment.
As shown in FIG. 7, the control unit 42 of the vanity 10b first detects the hand (human body) based on the detection information from the human body detection sensor 40, as in the description of FIG. By transmitting a control signal to the air conditioner 12 in response to the detection of the above, the air conditioner 12 is activated and the non-detection of the hand is determined (steps S111 to 113 in FIG. 7).

When the control unit 42 determines that the detection state has been switched to the non-detection state, the control unit 42 activates the timer 60 and causes the timer 60 to start timing (step S114 in FIG. 7). Further, when the control unit 42 determines that the detection state has been switched to the non-detection state, the control unit 42 closes the switching valve 46 to stop the water discharge from the water discharge unit 22a of the faucet device 22.

After activating the timer 60, the control unit 42 determines whether or not a predetermined time has elapsed from the timing when the detection information of the human body detection sensor 40 is switched from the detection state to the non-detection state (step S115 in FIG. 7). ..

When the control unit 42 determines that the predetermined time has elapsed, the control unit 42 transmits a control signal to the air conditioner 12 to stop the operation of the air conditioner 12 (step S116 in FIG. 7). Further, when the control unit 42 determines that the predetermined time has elapsed, the time counting of the timer 60 is stopped (step S117 in FIG. 7).

When the control unit 42 determines in step S115 that the predetermined time has not elapsed, whether or not the control unit 42 subsequently switches from the non-detection state of the hand to the detection state based on the detection information from the human body detection sensor 40. (Step S118 in FIG. 7).

When it is determined that the non-detection state is continued, the control unit 42 returns to the process of step S115 and determines whether or not the predetermined time has elapsed.

On the other hand, when the control unit 42 determines that the detection information has been switched from the non-detection state to the detection state again before the elapse of the predetermined time, the operation of the timer 60 is stopped by resetting the timer 60, and the predetermined state is determined. Reset the timekeeping (step S119 in FIG. 7). In other words, when the control unit 42 detects the human body before the elapse of the predetermined time, the control unit 42 returns the time counting of the predetermined time to the initial value.

After resetting the timer 60, the control unit 42 returns to the process of step S113 and determines that the hand is not detected. Then, the control unit 42 repeats the same process thereafter.

As described above, in the vanity 10b, the control unit 42 sends the control signal to the air conditioner when a predetermined time elapses from the timing when the detection information is switched from the detection state to the non-detection state after the air conditioner 12 is activated. By transmitting to 12, the air conditioner 12 can be stopped. As a result, the air conditioner 12 can be automatically stopped when the user leaves the vanity 10b, the running cost can be further reduced, and a comfortable wash space WS with better usability can be provided. it can.

Further, in the vanity 10b, the control unit 42 resets the time counting of the predetermined time when the detection information is switched from the non-detection state to the detection state again before the elapse of the predetermined time. As a result, even if the user temporarily leaves the vanity 10b while brushing his teeth, the air conditioner 12 is unintentionally stopped by being detected again before the lapse of a predetermined time. It is possible to prevent it from being lost. For example, it is possible to prevent the air conditioner 12 from repeatedly starting and stopping. Further, for example, it is possible to prevent the air conditioner 12 from stopping once when different users continuously use the vanity 10b. Therefore, it is possible to further improve the usability of the wash space WS while further suppressing the running cost.

(Second Embodiment)
FIG. 8 is a block diagram schematically showing the washroom space system and the washstand according to the second embodiment.
As shown in FIG. 8, the vanity 10c includes a temperature sensor 62. The temperature sensor 62 can measure the temperature in the wash space WS. The temperature sensor 62 is connected to the control unit 42. The temperature sensor 62 inputs the measurement information of the temperature in the wash space WS to the control unit 42.

FIG. 9 is a side view schematically showing the vanity table according to the second embodiment.
As shown in FIG. 9, the temperature sensor 62 is provided at the lower end of the mirror cabinet 26, for example. The distance D1 between the temperature sensor 62 and the faucet device 22 is closer than the height distance D2 from the temperature sensor 62 to the floor surface. The distance D1 between the temperature sensor 62 and the faucet device 22 is, for example, the shortest distance between the temperature sensor 62 and the faucet device 22.

In this way, the temperature sensor 62 is arranged in the vicinity of the faucet device 22. The temperature sensor 62 is arranged, for example, above the upper end of the bowl portion 20a of the wash bowl 20 and below the lower end of the mirror cabinet 26. The temperature sensor 62 is arranged at a position where it overlaps with the back guard portion 20b in the front-rear direction, for example. However, the position of the temperature sensor 62 is not limited to this, and may be any position where the temperature in the wash space WS can be appropriately measured.

For example, if the temperature sensor 62 is arranged in a closed space such as the inside of the support base 24 or the inside of the mirror cabinet 26, the temperature in the wash space WS may not be measured appropriately. Therefore, it is preferable that the temperature sensor 62 is arranged at a position exposed to the outside. In other words, it is preferable that the temperature sensor 62 is arranged at a position in the wash space WS that directly contacts the air.

The temperature sensor 62 is provided, for example, at the lower end of the mirror cabinet 26 or at the front surface of the back guard portion 20b. Thereby, the temperature in the wash space WS can be appropriately measured.

FIG. 10 is a flowchart schematically showing an example of the operation of the vanity according to the second embodiment.
In FIG. 10, an example of the operation of the vanity 10c is taken as an example in which the air conditioner 12 is set to the cooling operation mode and the air conditioner 12 has two operation modes, operation mode A and operation mode B. explain. The operation mode A is a recommended operation mode when the room temperature of the wash space WS is equal to or higher than a preset predetermined threshold value. The operation mode B is a recommended operation mode when the room temperature of the wash 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. The 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 this, and for example, an operation mode having a low set temperature may be set as an operation mode A, and an operation mode having a high set temperature may be set as an operation mode B or the like. For example, the operation mode A may be set to the cooling operation mode, and the operation mode B may be set to the heating operation mode.

As shown in FIG. 10, the control unit 42 of the vanity 10c determines whether or not the non-detection state of the hand (human body) has been switched to the detection state based on the detection information from the human body detection sensor 40. When it is determined that the non-detection state has been switched to the detection state, it is subsequently determined whether or not the room temperature of the wash space WS is equal to or higher than the threshold value based on the measurement information from the temperature sensor 62 (steps S121 and S122 in FIG. 10). ).

When the control unit 42 determines that the threshold value is equal to or higher than the threshold value, the control unit 42 transmits a control signal for activating the air conditioner 12 in the operation mode A to the air conditioner 12 (step S123 in FIG. 10). The air conditioner 12 is activated in the operation mode A in response to the reception of the control signal.

On the other hand, when the control unit 42 determines that the value is less than the threshold value, the control unit 42 transmits a control signal for activating the air conditioner 12 in the operation mode B to the air conditioner 12 (step S124 in FIG. 10). The air conditioner 12 is activated in the operation mode B in response to the reception of the control signal.

In this way, in the vanity 10c, the control unit 42 can transmit the control signal to be activated in the operation mode corresponding to the temperature of the wash space WS to the air conditioner 12 based on the measurement information of the temperature sensor 62. It has a good structure. As a result, the air conditioner 12 can be automatically started in the operation mode corresponding to the temperature of the wash space WS, and the usability of the wash space WS can be further improved. For example, the set temperature, the air volume, and the like can be automatically set according to the situation of the wash space WS, and the comfort can be improved.

FIG. 11 is a flowchart schematically showing another operation of the vanity according to the second embodiment.
FIG. 11 schematically shows a part of the operation of the vanity 10c. The operation of FIG. 11 is executed after transmitting a control signal to the air conditioner 12 and activating the air conditioner 12. That is, the operation of FIG. 11 is executed after step S123 or step S124 of FIG. Further, in FIG. 11, the operation mode A and the operation mode B are the same as those described with respect to FIG.

The control unit 42 of the vanity 10c transmits a control signal to activate the air conditioner 12, and then determines whether or not the room temperature of the vanity WS is equal to or higher than the threshold value based on the measurement information from the temperature sensor 62. (Step S131 in FIG. 11).

When the control unit 42 determines that the threshold value is equal to or higher than the threshold value, the control unit 42 subsequently determines whether or not the current operation mode of the air conditioner 12 is the operation mode B (step S132 in FIG. 11).

When the control unit 42 determines that the operation mode B is set, the control unit 42 transmits a control signal for changing the operation mode of the air conditioner 12 from the operation mode B to the operation mode A to the air conditioner 12 (step of FIG. 11). S133). The air conditioner 12 changes the operation mode from the operation mode B to the operation mode A in response to the reception of the control signal. Further, when the control unit 42 determines that the operation mode A is set, the control unit 42 returns to the determination of the room temperature in step S131 without transmitting the control signal.

When the control unit 42 determines in step S131 that the value is less than the threshold value, the control unit 42 subsequently determines whether or not the current operation mode of the air conditioner 12 is the operation mode A (step S134 in FIG. 11).

When the control unit 42 determines that the operation mode A is set, the control unit 42 transmits a control signal for changing the operation mode of the air conditioner 12 from the operation mode A to the operation mode B to the air conditioner 12 (step of FIG. 11). S135). The air conditioner 12 changes the operation mode from the operation mode A to the operation mode B in response to the reception of the control signal. Further, when the control unit 42 determines that the operation mode B is set, the control unit 42 returns to the determination of the room temperature in step S131 without transmitting the control signal.

In this way, in the vanity 10c, after the control unit 42 activates the air conditioner 12, the control signal based on the measurement information is transmitted to the air conditioner 12, so that the operation according to the measurement information is performed by the air conditioner 12. Can be executed. Thereby, more suitable control can be performed according to the temperature of the wash space WS. For example, it is possible to suppress unnecessary operations of the air conditioner 12, suppress unnecessary power consumption due to unnecessary operations, and suppress running costs.

FIG. 12 is a block diagram schematically showing a modified example of the wash space system and the vanity according to the second embodiment.
As shown in FIG. 12, in the vanity 10d, the faucet device 22 has an operation unit 70 and a flow rate adjusting valve 72. Further, in the faucet device 22 of the vanity 10d, the switching valve 46 is omitted.

The operation unit 70 receives an operation from a user or the like. The operation unit 70 is, for example, a handle or a lever. The flow rate adjusting valve 72 is provided between the water supply source and the water discharge unit 22a, and by opening and closing the flow path according to the operation of the operation unit 70, the water discharge from the water discharge unit 22a and the stop of the water discharge are switched and operated. The flow rate of water discharged from the water discharge unit 22a is adjusted according to the operation amount of the unit 70. That is, in this example, the faucet device 22 is a so-called manual faucet.

In this example, an example of a manual faucet in which the flow rate adjusting valve 72 mechanically switches the water discharge from the water discharge unit 22a and the stop of the water discharge is shown. However, the configuration of the manual faucet is not limited to the above configuration. For example, the operation input of the operation unit 70 may be input to the control unit 42, and the control unit 42 may open and close the switching valve 46 to switch the water discharge from the water discharge unit 22a and the stop of the water discharge. In this case, the operation unit 70 may be a handle, a lever, or the like, or a touch sensor or the like.

The faucet device 22 further includes a water discharge detection unit 74. The water discharge detection unit 74 detects the water discharge from the water discharge unit 22a and the stop of the water discharge. For the water discharge detection unit 74, for example, a flow rate sensor or the like is used. The water discharge detection unit 74 is connected to the control unit 42. The water discharge detection unit 74 inputs water discharge information based on the detection result to the control unit 42. As a result, even when the faucet device 22 is a mechanical manual faucet, the control unit 42 can grasp the presence or absence of water discharge. For example, when the operation input of the operation unit 70 is input to the control unit 42, the water discharge detection unit 74 can be omitted.

In the vanity 10d, the human body detection sensor 40 detects a human body approaching the vanity 10d. In other words, the human body detection sensor 40 detects a human body approaching the washbasin 20 or the faucet device 22. In this case, as the human body detection sensor 40, for example, a distance measuring sensor using infrared light or the like, a pyroelectric sensor, or a radio wave sensor such as a microwave sensor can be used. As described above, the human body detection sensor 40 is not limited to the one that detects the hand of the user or the like, and may be any sensor that can detect the approaching human body. The human body detection sensor 40 may be appropriately selected according to the form of water discharge such as a manual faucet or an automatic faucet.

In the vanity 10d, the detection range of the human body detection sensor 40 is preferably set to, for example, about 50 cm or more and 1 m or less. By setting the detection range of the human body detection sensor 40 to 50 cm or more, it is possible to detect an approaching human body even before the user or the like operates the operation unit 70. In other words, it is possible to detect an approaching human body even before the faucet device 22 starts spouting water. Thereby, for example, the air conditioner 12 can be started before the user or the like operates the operation unit 70 to discharge water. By setting the detection range of the human body detection sensor 40 to 1 m or less, it is possible to suppress the activation of the air conditioner 12 at an unintended timing such as entering the temporary wash space WS for collecting laundry. it can.

As described above, it is preferable that the detection range of the human body detection sensor 40 is set so that the human body can be detected even before the start of water discharge and is narrower than the wash space WS. By setting the detection range of the human body detection sensor 40 to 50 cm or more and 1 m or less, the human body can be detected even before the start of water discharge, and the space can be set to be narrower than the wash space WS.

FIG. 13 is a flowchart schematically showing another operation of the vanity according to the second embodiment.
FIG. 13 schematically shows a part of the operation of the vanity 10d. The operation of FIG. 13 is executed after transmitting the control signal to the air conditioner 12 and activating the air conditioner 12, similarly to the operation of FIG. At this time, in the vanity 10d, by configuring the human body detection sensor 40 and the like as described above, the human body can be detected even before the start of water discharge, the air conditioner 12 can be started, and the air conditioner 12 can be activated and the non-detection can be performed. By stopping the air conditioner 12, the air conditioner 12 can be stopped after the water discharge is stopped.

The control unit 42 of the vanity 10d transmits a control signal to activate the air conditioner 12, and then, based on the water discharge information from the water discharge detection unit 74, from the start of water discharge to the stop of water discharge of the faucet device 22. It is determined whether or not the water discharge period includes the above (step S141 in FIG. 13). The water discharge period may be a period from the start of water discharge to the stop of water discharge, or may be a period obtained by adding a predetermined time to the period from the start of water discharge to the stop of water discharge.

For example, the control unit 42 determines that the water discharge period is when the water discharge information is switched from stop to water discharge, and determines that the water discharge period is completed when the water discharge information is switched from water discharge to stop. Alternatively, the control unit 42 determines that the water discharge period is when the water discharge information is switched from stop to water discharge, and the water discharge period is terminated when a predetermined time elapses from the timing when the water discharge information is switched from water discharge to stop. judge.

When the control unit 42 determines that the water discharge period is not reached, the control unit 42 transmits a control signal based on the measurement information to the air conditioner 12 to perform an operation according to the measurement information, as in the explanation with respect to FIG. (Steps S142 to S146 in FIG. 13). Steps S142 to S146 of FIG. 13 are substantially the same as steps S131 to S135 of FIG.

On the other hand, when the control unit 42 determines that the water discharge period is reached, the control unit 42 does not transmit the control signal based on the measurement information.

In the vanity 10d, since the temperature sensor 62 is provided near the faucet device 22, the temperature is closer to the user than the air conditioner 12 which is likely to be arranged near the ceiling or the floor. Can be measured. Therefore, the influence of the hot air or cold air blown from the air conditioner 12 can be suppressed, and the temperature of the wash space WS can be measured more accurately.

Further, in the vanity 10d, the control signal based on the measurement information is not transmitted during the predetermined water discharge period including the start of the water discharge of the faucet device 22 to the stop of the water discharge, so that the vicinity of the faucet device 22 is not transmitted. Even when the temperature sensor 62 is arranged in the faucet device 22, the influence of cold water or hot water discharged from the faucet device 22 can be suppressed. Therefore, the temperature of the wash space WS can be measured more accurately.

In the vanity 10d, the water discharge detection unit 74 detects the presence or absence of water discharge from the water discharge unit 22a. For example, when the human body detection sensor 40 detects a user's hand and opens and closes the switching valve 46 to switch between starting and stopping water discharge, the human body detection sensor 40 does not need to provide the water discharge detection unit 74. The presence or absence of water discharge may be detected based on the detection information.

In this case, for example, by setting two threshold values in the human body detection sensor 40, two detection ranges of the human body approaching the vanity 10d and the detection range of the hand extended to the wash bowl 20 are detected. A range is provided in the human body detection sensor 40, and the detection range of the human body is made wider than the detection range of the hand.

The control unit 42 activates the air conditioner 12 in response to the detection of the human body, and causes the water discharge unit 22a to start spouting water in response to the detection of the hand. As a result, the operations of steps S142 to S146 of FIG. 13 can be performed between the start of the air conditioner 12 and the start of water discharge, and between the stop of water discharge and the stop of the air conditioner 12.
