Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in all of Patent Documents 1 to 3, since mist generating means for supplying mist into the bathroom is required, there is a problem that the above-described bathroom apparatus becomes expensive. Further, in order to attach moisture to clothes to remove wrinkles from the clothes, it is necessary to uniformly attach moisture to the entire clothes. However, when a shower-like splash mist is supplied into the bathroom from a spray nozzle as in Patent Documents 1 and 2, moisture is likely to adhere only to the portion facing the ejection direction of the mist. Therefore, there is a problem that the wrinkles of the entire clothes cannot be sufficiently removed and the wrinkle removal performance is poor. On the other hand, when fine micro mist generated by evaporating hot water on a heat exchanger is supplied into the bathroom as in Patent Document 3, although moisture can be attached to the entire clothes, it is difficult for the humidity in the bathroom to rise. Therefore, there is a problem that not only the processing amount of clothes is limited, but also a long-time mist operation is required, resulting in an increase in operation cost.

[0006] The present invention solves the above problems, and an object of the present invention is to provide a bathroom apparatus capable of efficiently removing wrinkles from clothes at low cost without providing mist generating means, and a bathroom system using the same.

Means for Solving the Problems

[0007] According to a first aspect of the present technology, a blowing means for blowing air into the bathroom, an operation mode setting means for setting a wrinkle removal operation mode of clothes, and a control means, and a bathroom apparatus comprising: The control means has a control configuration for executing a wrinkle removal operation in which, when the wrinkle removal operation mode is set by the operation mode setting means, air is blown by the blowing means into the bathroom in a state where water or hot water in the bathtub is stored in the bathtub, and the bathroom is humidified by the bathtub water. A bathroom apparatus is provided.

[0008] If air is blown by a blowing means into a bathroom in a state where bathtub water is stored in a bathtub, the bathtub water can be evaporated to humidify the entire bathroom. Therefore, according to the first aspect, moisture can be evenly attached to clothes using a bathroom device without a mist generating means. Thereby, it is possible to efficiently remove wrinkles from a plurality of clothes at low cost.

[0009] According to a second aspect of the present technology, in the first aspect, the bathroom device is connected to a hot water supply device that supplies bathtub water of water or hot water to the bathtub, the control means has a control configuration for causing the hot water supply device to supply bathtub water to the bathtub when the ironing operation mode is set by the operation mode setting means.

[0010] According to the second aspect, since it is not necessary for the user to directly supply bathtub water to the bathtub, the usability can be improved. Also, usually, since the user does not know the supply amount of bathtub water suitable for humidifying the bathroom, there is a possibility that the bathtub may be supplied with bathtub water that is unnecessary for humidification. However, according to the second aspect, since the hot water supply device can supply the bathtub with the supply amount of bathtub water suitable for humidifying the bathroom, the bathroom can be efficiently humidified.

[0011] According to a third aspect of the present technology, in the second aspect, the control means acquires the initial room temperature in the bathroom when the ironing operation mode is set by the operation mode setting means, and has a control configuration for causing the hot water supply device to supply water as bathtub water to the bathtub when the initial room temperature in the bathroom is equal to or higher than the initial room temperature threshold value.

[0012] According to the third aspect, when the initial room temperature in the bathroom is equal to or higher than the initial room temperature threshold value, water is supplied from the hot water supply device to the bathtub as bathtub water, so the operation cost can be reduced.

[0013] According to a fourth aspect of the present technology, in the second or third aspect, the control means acquires the water temperature of the water supplied from the hot water supply device to the bathtub, When the water temperature of the water supplied from the water heater to the bathtub is lower than a predetermined initial water temperature threshold value, it has a control configuration for causing the water heater to supply hot water at a predetermined first start temperature to the bathtub as bathtub water.

[0014] According to the fourth aspect, even if the initial room temperature in the bathroom is equal to or higher than the initial room temperature threshold value, if the water temperature of the water supplied from the water heater to the bathtub is lower than the initial water temperature threshold value, hot water at the first start temperature is supplied from the water heater to the bathtub. Therefore, the bathroom can be efficiently humidified.

[0015] According to the fifth aspect of the present technology, in the second or fourth aspect, it has heating means for heating the air blown into the bathroom, When the wrinkle removal operation mode is set by the operation mode setting means, the control means acquires the initial room temperature in the bathroom, When the initial room temperature in the bathroom is lower than the initial room temperature threshold value, it executes preliminary heating for operating the blowing means and the heating means, and has a control configuration for causing the water heater to supply hot water at a predetermined second start temperature to the bathtub as bathtub water.

[0016] When the initial room temperature in the bathroom is low, the amount of saturated water vapor is low, so it becomes difficult for the bathtub water to evaporate and it becomes difficult to humidify the bathroom. However, according to the fifth aspect, when the initial room temperature in the bathroom is lower than the initial room temperature threshold value, the room temperature in the bathroom is raised by preliminary heating, so the bathroom can be efficiently humidified. Further, according to the fifth aspect, when the initial room temperature in the bathroom is lower than the initial room temperature threshold value, hot water at the second start temperature is supplied from the water heater to the bathtub, so the bathroom can be humidified more efficiently.

[0017] According to the sixth aspect of the present technology, in any one of the first to fifth aspects, it has notification means for notifying predetermined information, When the wrinkle removal operation mode is set by the operation mode setting means, the control means acquires the absolute humidity in the bathroom, In the initial stage of the wrinkle-removing operation, when the increase amount of the absolute humidity within a predetermined increase amount determination time is less than a predetermined increase amount threshold value, there is a control configuration for causing notification means to notify caution information for informing the user that the bathroom is in an environment where it is difficult to humidify.

[0018] For example, when the bathroom is in an environment where the bathroom window or the entrance / exit of the bathroom is open, or the bathtub is covered, even if air is blown by a blowing means into the bathroom in a state where bathtub water is stored in the bathtub, it is difficult to humidify the bathroom, and there is a risk that unnecessary operation will continue. However, according to the sixth aspect described above, when the increase amount of the absolute humidity within the increase amount determination time in the initial stage of the wrinkle-removing operation is less than the increase amount threshold value, caution information for informing the user that the bathroom is in an environment where it is difficult to humidify is notified from the notification means, so that the user can be made to check the inside of the bathroom at an early stage.

[0019] According to the seventh aspect of the present technology, in any one of the second to sixth aspects described above, When the wrinkle-removing operation mode is set by the operation mode setting means, the control means acquires the absolute humidity in the bathroom. In the initial stage of the wrinkle-removing operation, when the absolute humidity has not risen above a predetermined humidification threshold value when a predetermined initial determination time has elapsed, there is a control configuration for causing the hot water supply device to supply hot water at a predetermined first replenishment temperature as bathtub water to the bathtub.

[0020] Even if air is blown by a blowing means into the bathroom in a state where bathtub water is stored in the bathtub, when the absolute humidity in the bathroom does not rise to the humidification threshold value, it is considered that the bathroom is in a state where it is difficult to humidify. However, according to the seventh aspect described above, when the absolute humidity has not risen above the humidification threshold value when the initial determination time in the initial stage of the wrinkle-removing operation has elapsed, hot water at the first replenishment temperature is supplied from the hot water supply device to the bathtub, so that the inside of the bathroom can be humidified at an early stage.

[0021] According to the eighth aspect of the present technology, in the seventh aspect described above, When the initial determination time has elapsed and the absolute humidity has risen above the humidification threshold value, but after the passage of the initial determination time, if the absolute humidity has dropped below the humidification threshold value, the control means has a control configuration for causing the hot water supply device to supply hot water at a predetermined second replenishment temperature to the bathtub as bathtub water.

[0022] If the absolute humidity has risen above the humidification threshold value when the initial determination time has elapsed, it can be determined that the bathroom is in a humidifiable state. On the other hand, even if the absolute humidity has once risen above the humidification threshold value, for example, when the user enters and exits the bathroom, the absolute humidity in the bathroom may decrease, and there is a risk that sufficient moisture cannot be attached to the clothes. However, according to the eighth aspect described above, when the absolute humidity drops below the humidification threshold value after rising above the humidification threshold value, hot water at the second replenishment temperature is supplied from the hot water supply device to the bathtub, so that the inside of the bathroom can be quickly restored to a humid state.

[0023] According to the ninth aspect of the present technology, in any one of the first to eighth aspects described above, In the initial stage of the wrinkle removal operation, when the absolute humidity has risen above a predetermined humidification threshold value when a predetermined initial determination time has elapsed, and after the passage of the initial determination time, if the humid state where the absolute humidity is above the humidification threshold value continues for a predetermined humidification time, it has a control configuration for determining that the humidification is completed.

[0024] According to the eighth aspect described above, since the user does not need to judge the humid state in the bathroom, the usability can be improved.

[0025] According to the tenth aspect of the present technology, in any one of the first to ninth aspects described above, The bathtub has an automatic drain plug for opening and closing the drain port, When the wrinkle removal operation mode is set by the operation mode setting means, the control means has a control configuration for closing the drain port with the automatic drain plug.

[0026] According to the tenth aspect described above, since the user does not need to close the drain plug of the bathtub, the usability can be improved.

[0027] According to the eleventh aspect of the present technology, a bathroom system is provided which includes any one of the first to tenth bathroom apparatuses, a bathroom, and a bathtub.

[0028] According to the eleventh aspect, it is possible to efficiently remove wrinkles from a plurality of pieces of clothing at low cost.

With this configuration, the water supplied from the water supply pipe to the water supply passage 65 is heated by the combustion exhaust gas discharged from the hot water supply side burner unit 61 in the hot water supply side heat exchanger 62, and the heated hot water is supplied to the hot water supply terminal or the bathtub 1 via the hot water supply passage 66.

[0035] A hot water filling passage 67 branches from the hot water supply passage 66, and the hot water filling passage 67 communicates with a bathtub return passage 71 connected to the bathtub 1. The bathtub return passage 71, together with the bathtub forward passage 72, forms a reheating circuit between the bathtub 1 and the bathtub heat exchanger 75. The hot water filling passage 67 is provided with a pouring solenoid valve 68 for opening and closing the hot water filling passage 67, a flow sensor 69 for detecting the flow rate of the bathtub water supplied to the bathtub 1, and a bathtub water temperature sensor 70 for detecting the temperature of the water or hot water supplied to the bathtub 1. The bathtub return passage 71 is provided with a bathtub pump 74 for circulating the bathtub water in the bathtub 1 through the bathtub return passage 71 and the bathtub forward passage 72 during the reheating operation.

[0036] The heating side combustion unit 80 includes a heating return passage 85 connected to the upstream end of the heating side heat exchanger 82 and a heating forward passage 86 connected to the downstream end of the heating side heat exchanger 82. As described above, the heating return passage 85 and the heating forward passage 86 are connected to the heat exchanger 42 of the bathroom heating and drying machine 3, and the heating return passage 85 and the heating forward passage 86 form a heating circuit between the heating side heat exchanger 82 and the heat exchanger 42 of the bathroom heating and drying machine 3. A cistern 83 is interposed in the heating return passage 85. A makeup water passage 88 branched from the water supply passage 65 is connected to the cistern 83, and the makeup water passage 88 is provided with a makeup water solenoid valve 89 for opening and closing the makeup water passage 88. Further, a heating pump 84 for circulating hot water between the heating side combustion unit 80 and the heat exchanger 42 of the bathroom heating and drying machine 3 is provided in the heating return passage 85. A bathtub branch passage 76 is connected to the heating forward passage 86, and a reheating bathtub heat exchanger 75 is provided in the middle of the bathtub branch passage 76.

[0037] Below the hot water supply side burner unit 61 and the heating side burner unit 81, a hot water supply side combustion fan 90 and a heating side combustion fan 91 are provided respectively (see Fig. 2). By the operation of these fans 90 and 91, the outside air inhaled into the hot water supply device 6 is supplied as combustion air to the hot water supply side burner unit 61 and the heating side burner unit 81.

[0038] On the inner peripheral surface of the bathtub 1, bathtub fittings 10 are provided. At the bottom of the bathtub 1, a drain port 11 for discharging the bathtub water in the bathtub 1 to the outside is opened. An automatic drain plug 12 that can automatically open and close the drain port 11 is provided at the drain port 11. The bathtub fittings 10 are connected to the aforementioned bath return passage 71 and bath forward passage 72.

[0039] On the wall surface of the bathroom BR, a remote control (operation mode setting means) 100 for setting each operation mode of the bathroom heater / dryer 3 and the hot water supply device 6 is installed. The remote control 100 includes a heating operation switch 102, a ventilation operation switch 103, a drying operation switch 104, a wrinkle removal operation switch 105 for setting each operation mode of the bathroom heater / dryer 3, a water filling operation switch 106, a supplementary heating operation switch 107 for setting each operation mode of the hot water supply device 6, an operation condition setting switch 108 for setting operation conditions such as temperature and operation time in each operation mode of the bathroom heater / dryer 3 and the hot water supply device 6, a display unit 109 for displaying predetermined character image information, a speaker (notification means) 110 for notifying predetermined voice information, etc. When the user operates each switch of the remote control 100, operation control signals are respectively transmitted to a bathroom heater / dryer controller C1 and a hot water supply controller C2 described later, and each operation mode is executed under the set operation conditions. Note that individual remote controls for setting the respective operation modes of the bathroom heater / dryer 3 and the hot water supply device 6 may be provided, or both a common remote control and individual remote controls may be provided. Also, a plurality of operation modes may be configured to be set by combining one operation switch and an operation condition setting switch.

[0040] The bathroom heating and drying controller C1, the hot water supply controller C2, and the drain plug controller C3 are all composed of a microcomputer equipped with a CPU, ROM, RAM, A / D converter, timer, interface, etc., and programs corresponding to the control of the operations of the bathroom heating and drying machine 3, the hot water supply device 6, and the automatic drain plug 12 are installed in advance.

[0041] As shown in FIG. 2, the bathroom heating and drying controller C1 is connected to a room temperature sensor 33, a humidity sensor 34, a hot water temperature sensor 44, etc., and these detection signals are input. Also, the bathroom heating and drying controller C1 is connected to a circulation fan 40, a ventilation fan 41, a movable louver 35, a thermostatic valve 43, etc., and controls their operations. The hot water supply controller C2 is connected to a flow sensor 69, a bathtub water temperature sensor 70, etc., and these detection signals are input. Also, the hot water supply controller C2 is connected to a hot water supply side burner unit 61, a heating side burner unit 81, a hot water supply side combustion fan 90, a heating side combustion fan 91, a hot water injection solenoid valve 68, a bathtub pump 74, a heating pump 84, a make-up water solenoid valve 89, etc., and controls their operations. The drain plug controller C3 is connected to the automatic drain plug 12 and controls its operation. Also, the bathroom heating and drying controller C1 and the hot water supply controller C2 are each connected to be capable of two-way communication with a remote controller 100. Also, the bathroom heating and drying controller C1 is connected to be capable of two-way communication with the hot water supply controller C2 and the drain plug controller C3.

[0042] The bathroom heating and drying controller C1 includes, as functional configuration means, a heating control means 150 for controlling the heating operation, a ventilation control means 151 for controlling the ventilation operation, a drying control means 152 for controlling the drying operation of clothes, a wrinkling removal control means 153 for controlling the wrinkling removal operation of clothes, and a notification control means 154 for controlling the notification of predetermined information from the display unit 109 and the speaker 110. Therefore, the wrinkling removal control means 153 of the bathroom heating and drying controller C1 corresponds to the control means for controlling the operation of each device in the wrinkling removal operation. The hot water supply controller C2 includes, as functional configuration means, a hot water supply side control means 200 for controlling the operation of the hot water supply side combustion unit 60 and a heating side control means 201 for controlling the operation of the heating side combustion unit 80. The drain plug controller C3 includes, as functional configuration means, a drain plug control means 300 for controlling the operation of the automatic drain plug 12 in response to a control signal from the bathroom heating and drying controller C1. Note that the hot water supply controller C2 may have a part of the functions executed by the wrinkling removal control means 153.

[0043] Next, the operations of the bathroom heating and drying machine 3, the hot water supply device 6, and the automatic drain plug 12 will be described. First, the operations of each device in the heating operation mode, the ventilation operation mode, and the clothes drying operation mode will be described. The operations of each device in these operation modes are the same as those in the prior art. By the user operating each operation switch 102, 103, 104, each operation mode is set. When changing the operation time from the initial value, the user operates the operation condition setting switch 108 to set the operation time.

[0044] When the user turns on the heating operation switch 102 and the heating operation mode is set, a control signal for starting the heating operation is sent from the remote controller 100 to the bathroom heating and drying controller C1, and the heating operation is started by the heating control means 150. In the heating operation, the heating control means 150 sends a control signal for starting the combustion operation of the heating-side combustion unit 80 to the hot water supply controller C2. Then, the hot water supply controller C2 starts the combustion operation of the heating-side combustion unit 80 according to the control signal, operates the heating pump 84, and supplies hot water at a predetermined temperature to the heat exchanger 42 of the bathroom heating and drying machine 3. Then, the heating control means 150 opens the thermostatic valve 43 and operates the circulation fan 40 to execute a heating operation in which warm air is circulated in the bathroom BR for the set operation time.

[0045] When the user turns on the ventilation operation switch 103 and the ventilation operation mode is set, a control signal for starting the ventilation operation is sent from the remote controller 100 to the bathroom heating and drying controller C1, and the ventilation operation is started by the ventilation control means 151. In the ventilation operation, the ventilation control means 151 does not send a control signal to the hot water supply controller C2, closes the thermostatic valve 43, stops the circulation fan 40, and operates only the ventilation fan 41 for the set operation time. As a result, the air in the bathroom BR is discharged to the outside and the bathroom BR is ventilated.

[0046] When the user turns on the drying operation switch 104 and the drying operation mode is set, a control signal for starting the drying operation is sent from the remote control 100 to the bathroom heating and drying controller C1, and the drying control means 152 starts the drying operation of the clothes. The drying operation is executed with the clothes hung in the bathroom BR. Similar to the heating operation, the drying control means 152 sends a control signal to the hot water supply controller C2 to start the combustion operation of the heating side combustion unit 80. Then, the hot water supply controller C2 starts the combustion operation of the heating side combustion unit 80 according to the control signal, operates the heating pump 84, and supplies hot water at a predetermined temperature to the heat exchanger 42 of the bathroom heating and dryer 3. Then, the drying control means 152 opens the thermostatic valve 43 and operates the set operation time, the circulation fan 40, and the ventilation fan 41. By the operation of the circulation fan 40, the air in the bathroom BR sucked toward the heat exchanger 42 is heated by the heat exchanger 42, blown out into the bathroom BR as warm air, and the temperature in the bathroom BR rises. Also, by the operation of the ventilation fan 41, the moist air released from the clothes is discharged to the outside, and the clothes hung in the bathroom BR are gradually dried.

[0047] Next, with reference to FIGS. 3 to 7, the operation of each device in the ironing operation mode will be described. Note that the operation conditions such as the temperature and time described later in the ironing operation can be obtained in advance by experiments according to the size of the bathroom BR and the performance of each device.

[0048] The wrinkle-removing operation is executed with clothes hung in the bathroom BR. When the user turns on the wrinkle-removing operation switch 105 and the wrinkle-removing operation mode is set, a control signal is sent from the remote controller 100 to the bathroom heating and drying controller C1 to start the wrinkle-removing operation, and the wrinkle-removing operation is started by the wrinkle-removing control means 153 (in step S1, Yes). In the wrinkle-removing operation, first, in order to confirm to the user whether the environment in the bathroom BR is suitable for the wrinkle-removing operation, the wrinkle-removing control means 153 sends a control signal to cause the remote controller 100 to notify the first attention information, and notifies the first attention information (for example, "Please open the bathtub lid" or "Is the bathroom window closed?") from the speaker 110, and starts a standby timer that measures a standby time (for example, 2 minutes) (steps S2 to S3). At this time, the first attention information composed of character image information may be displayed on the display unit 109 of the remote controller 100.

[0049] When the standby time elapses (in step S4, Yes), the wrinkle-removing control means 153 sends a control signal to the drain plug controller C3 to close the automatic drain plug 12 (step S5). Then, the drain plug controller C3 closes the automatic drain plug 12 according to the control signal (steps S301 to S302).

[0050] Next, the wrinkle-removing control means 153 starts the operation of the circulation fan 40 at the set rotation speed, and operates the movable louver 35 so that air is blown from the air outlet 32 toward the bathtub 1 (step S6). Further, when the wrinkle-removing control means 153 starts the operation of the circulation fan 40, it acquires the initial room temperature in the bathroom BR from the detection signal output from the room temperature sensor 33, and determines whether the initial room temperature in the bathroom BR is equal to or higher than a predetermined initial room temperature threshold value (for example, 15°C) (step S7). In the wrinkle-removing operation, different from the drying operation, the ventilation fan 41 is not operated until the humidification in the bathroom BR is completed, and the air circulates in the bathroom BR.

[0051] At this time, when the initial room temperature in the bathroom BR is equal to or higher than the initial room temperature threshold value (Yes in step S7), the wrinkle removal control means 153 transmits a control signal to the hot water supply controller C2 to cause water to be supplied as bathtub water to the bathtub 1 (step S8). Then, the hot water supply controller C2 opens the injection solenoid valve 68 according to the control signal and supplies water to the bathtub 1 until the flow rate of the bathtub water detected by the flow rate sensor 69 reaches a predetermined supply amount (for example, 20 L) (steps S201 to S203). When the supply of bathtub water to the bathtub 1 is completed (Yes in step S203), the hot water supply controller C2 closes the injection solenoid valve 68 and transmits a control signal indicating the completion of the supply of bathtub water to the bathtub 1 and the water temperature of the water output from the bathtub water temperature sensor 70 to the bathroom heating and drying controller C1 (steps S204 to S205). Therefore, if the initial room temperature in the bathroom BR at the initial stage of the wrinkle removal operation is equal to or higher than the initial room temperature threshold value that can contain a large amount of water vapor, normal temperature water is supplied as bathtub water to the bathtub 1 without performing a combustion operation by the hot water supply device 6. Thereby, the operation cost can be reduced. Note that the bathtub 1 has a large upward opening, and if air is blown into the bathroom BR, the bathtub water stored in the bathtub 1 can be evaporated, so that the bathroom BR can be efficiently humidified even with a small amount of bathtub water. For this reason, as described above, the supply amount of bathtub water to the bathtub 1 can be made sufficiently less than the normal hot water filling amount (for example, 100 L or more) filled from the hot water supply device 6 to the bathtub 1 during the hot water filling operation, and the operation cost can be further reduced.

[0052] Next, when the wrinkle removal control means 153 receives a control signal for the completion of the supply of the bathtub water and the control of the water temperature of the water supplied to the bathtub 1 from the hot water supply controller C2 (Yes in step S9), it determines whether the water temperature of the water supplied to the bathtub 1 obtained is equal to or higher than a predetermined initial water temperature threshold value (for example, 30°C) (step S10). At this time, when the water temperature is low (No in step S10), even if air is blown into the bathroom BR in a state where water is stored in the bathtub 1, it is difficult for the bathtub water to evaporate, and it takes a long time to increase the absolute humidity in the bathroom BR. For this reason, the wrinkle removal control means 153 transmits a control signal to the hot water supply controller C2 to start the combustion operation of the hot water supply side combustion unit 60 and supply hot water at a predetermined first start temperature (for example, 35°C) to the bathtub 1 (step S11). Then, the hot water supply controller C2 starts the combustion operation of the hot water supply side combustion unit 60 according to the control signal (steps S211 to S212). And the hot water supply controller C2 opens the pouring solenoid valve 68 and supplies hot water at the first start temperature to the bathtub 1 until the flow rate of the bathtub water detected by the flow rate sensor 69 reaches a predetermined supply amount (for example, 20 L) (steps S213 to S214). Thereby, the absolute humidity in the bathroom BR can be increased early in the initial stage of the wrinkle removal operation. When the supply of the bathtub water to the bathtub 1 is completed, the hot water supply controller C2 ends the combustion operation of the hot water supply side combustion unit 60, closes the pouring solenoid valve 68, and transmits a control signal for the completion of the supply of the bathtub water to the bathtub 1 to the bathroom heating and drying controller C1 (steps S215 to S217). When the bathroom heating and drying controller C1 receives a control signal for the completion of the supply of the bathtub water to the bathtub 1 from the hot water supply controller C2 (Yes in step S12), the wrinkle removal control means 153 proceeds to the humidity addition determination described later. If the water temperature of the water supplied to the bathtub 1 is less than the initial water temperature threshold value, the combustion operation of the hot water supply side combustion unit 60 may be started before the supply of water to the bathtub 1 or before the supply of water is completed, and hot water at the first start temperature may be supplied to the bathtub 1.

[0053] On the other hand, when the initial room temperature in the bathroom BR is low (No in step S7), since the amount of saturated water vapor is low, even if air is blown into the bathroom BR in a state where water is stored in the bathtub 1, it takes a long time to increase the absolute humidity in the bathroom BR. Therefore, the wrinkle removal control means 153 transmits a control signal to start the combustion operation of the heating side combustion unit 80 to the hot water supply controller C2 and starts a preheating timer for measuring the preheating time (for example, 10 minutes) in the same manner as the heating operation described above (steps S21 to S22). Then, the hot water supply controller C2 starts the preheating timer in response to the control signal, starts the combustion operation of the heating side combustion unit 80, operates the heating pump 84, and supplies hot water at a predetermined temperature to the heat exchanger 42 of the bathroom heating and drying machine 3 (steps S221 to S223). Further, the wrinkle removal control means 153 opens the thermostatic valve 43 and executes a preheating operation for circulating warm air in the bathroom BR (step S23). As a result, the air sucked into the case body 30 from the suction port 31 is heated by the heat exchanger 42, and the warm air is circulated into the bathroom BR by the circulation fan 40, so that the temperature in the bathroom BR rises.

[0054] When the preliminary heating starts, in the same manner as described above, the wrinkle removal control means 153 transmits a control signal to the hot water supply controller C2 to start the combustion operation of the hot water supply side combustion unit 60 and supply hot water at a predetermined second start temperature (for example, 35°C) to the bathtub 1 (step S24). Then, the hot water supply controller C2 starts the combustion operation of the hot water supply side combustion unit 60 in response to the control signal in the same manner as described above (steps S211 to S212). And the hot water supply controller C2 opens the pouring solenoid valve 68 and supplies hot water at the second start temperature to the bathtub 1 until the flow rate of the bathtub water detected by the flow rate sensor 69 reaches a predetermined supply amount (for example, 20 L) (steps S213 to S214). Thereby, the absolute humidity in the bathroom BR can be efficiently increased. Note that the first start temperature and the second start temperature may be the same or different. Also, the hot water supply device 6 may set the supply temperature and supply amount of the hot water to the bathtub 1 according to the control signal from the bathroom heating and drying machine 3, or may supply hot water to the bathtub 1 at the supply temperature and supply amount set in advance in the hot water supply device 6. When the supply of the bathtub water to the bathtub 1 is completed, the hot water supply controller C2 ends the combustion operation of the hot water supply side combustion unit 60, closes the pouring solenoid valve 68, and transmits a control signal indicating the completion of the supply of the bathtub water to the bathtub 1 to the bathroom heating and drying controller C1 (steps S215 to S217). When the bathroom heating and drying controller C1 receives the control signal indicating the completion of the supply of the bathtub water to the bathtub 1 from the hot water supply controller C2 and the preliminary heating time has elapsed (Yes in steps S25 and S26, Yes in step S224), the wrinkle removal control means 153 closes the thermostatic valve 43 with the circulation fan 40 operating (step S27), and the hot water supply controller C2 ends the combustion operation of the heating side combustion unit 80 (step S225). Note that the preliminary heating may determine the end of heating according to the room temperature in the bathroom BR. Also, the supply of hot water from the hot water supply device 6 to the bathtub 1 may be after the preliminary heating.

[0055] When the bathtub water is supplied to the bathtub 1 as described above, the wrinkle removal control means 153 starts acquiring the absolute humidity in the bathroom BR based on the detection signal output from the humidity sensor 34, and measures the rise amount determination time (for example, 1 minute) for determining the increase amount of the absolute humidity in the bathroom BR at the initial stage of the wrinkle removal operation, and the initial determination time (a time longer than the rise amount determination time, for example, 10 minutes) for determining the absolute humidity in the bathroom BR at the initial stage of the wrinkle removal operation. The initial determination timer is started (step S31). Then, until the initial determination time elapses, each time the rise amount determination time arrives, the wrinkle removal control means 153 determines whether the increase amount of the absolute humidity within the current rise amount determination time is equal to a predetermined rise amount threshold value (for example, 0.002 kg / m 3)Determine whether it is as described above (Steps S32 to S33). At this time, if the increase amount of the absolute humidity within the increase amount determination time is less than the increase amount threshold (No in Step S33), start a new increase amount determination timer (Step S41). If it is within the initial determination time (No in Step S42), determine whether the increase amount of the absolute humidity within the next increase amount determination time is greater than or equal to the increase amount threshold (Steps S32 to S33). Since the bathroom BR is a relatively enclosed space, if air is blown into the bathroom BR made into an environment where it is easy to humidify as described above, the absolute humidity will increase in a short time. However, for example, when the user misses the previous first caution information and the wrinkling operation is started in an environment where the bathtub 1 is covered or the window of the bathroom BR is open, the increase amount of the absolute humidity becomes small. Therefore, if the increase amount of the absolute humidity within the increase amount determination time remains small until the initial determination time elapses (No in Step S33, Yes in Step S42), the wrinkling control means 153 causes the remote controller 100 to notify the second caution information (for example, "The humidity is not increasing. Is the lid of the bathtub open?", "Is the window of the bathroom closed?", or "Is the drain plug closed?" etc.), stops the circulation fan 40, and stops the wrinkling operation (Steps S43 to S44). Thereby, it is possible to prevent the wrinkling operation from continuing in an environment where it is difficult to humidify the inside of the bathroom BR, and it is possible to improve the environment of the bathroom BR for the user. Note that the determination of the increase amount of the absolute humidity may be performed only once.

[0056] If the increase amount of the absolute humidity within the increase amount determination time at the initial stage of the wrinkling operation is greater than or equal to the increase amount threshold (Yes in Step S33), the wrinkling control means 153 further determines that when the initial determination time has elapsed, the absolute humidity is a predetermined humidification threshold (for example, 0.018 kg / m 3)Determine whether it has risen up to this point (Steps S34 - S35). That is, a certain absolute humidity or more is required to evenly attach moisture to the clothing. However, even if the increase in absolute humidity in the initial stage is large, the absolute humidity may not rise to a level sufficient to fully humidify the clothing depending on the temperature of the bathtub water, the room temperature in the bathroom BR, etc. Therefore, if the absolute humidity has not risen above the humidification threshold when the initial determination time has elapsed (Yes in Step S34, No in Step S35), it may take a long time to increase the absolute humidity in the bathroom BR. For this reason, the wrinkle removal control means 153 sends a control signal to the hot water supply controller C2 to start the combustion operation of the hot water supply side combustion unit 60 and supply hot water at a predetermined first replenishment temperature (for example, 40°C) to the bathtub 1 (Step S36). Then, the hot water supply controller C2 starts the combustion operation of the hot water supply side combustion unit 60 in response to the control signal in the same manner as above (Steps S211 - S212). And the hot water supply controller C2 opens the pouring solenoid valve 68 and supplies hot water at the first replenishment temperature to the bathtub 1 until the flow rate of the bathtub water detected by the flow rate sensor 69 reaches a predetermined supply amount (for example, 20L) (Steps S213 - S214). Thereby, the absolute humidity in the bathroom BR can be increased early in the initial stage of the wrinkle removal operation. When the supply of bathtub water to the bathtub 1 is completed, the hot water supply controller C2 ends the combustion operation of the hot water supply side combustion unit 60, closes the pouring solenoid valve 68, and sends a control signal of the completion of the supply of bathtub water to the bathtub 1 to the bathroom heating and drying controller C1 (Steps S215 - S217).

[0057] When the initial determination time has elapsed, whether the absolute humidity has risen above the humidification threshold (Yes in step S35), or when the initial determination time has elapsed and the absolute humidity is less than the humidification threshold, but when hot water is supplied from the hot water supply device 6 to the bathtub 1 (No in step S35, Yes in step S37), the wrinkle removal control means 153 starts a humidification determination timer for measuring a predetermined humidification time (for example, 20 minutes) (step S51). Then, the wrinkle removal control means 153 determines whether the humidified state where the absolute humidity is above the humidification threshold continues for the humidification time (steps S52 to S53). At this time, for example, when the user opens the entrance of the bathroom BR, the absolute humidity in the bathroom BR may decrease, and the amount of moisture adhering to the clothes may decrease. Therefore, if the absolute humidity becomes less than the humidification threshold before the humidification time elapses (No in step S52, No in step S53), the wrinkle removal control means 153 sends a control signal to the hot water supply controller C2 to start the combustion operation of the hot water supply side combustion unit 60 and supply hot water at a predetermined second replenishment temperature (for example, 40°C) to the bathtub 1 (step S54). Then, the hot water supply controller C2 starts the combustion operation of the hot water supply side combustion unit 60 according to the control signal in the same manner as above (steps S211 to S212). And the hot water supply controller C2 opens the hot water injection solenoid valve 68 and supplies hot water at the second replenishment temperature to the bathtub 1 until the flow rate of the bathtub water detected by the flow rate sensor 69 reaches a predetermined supply amount (for example, 20L) (steps S213 to S214). Thereby, the bathroom BR can be quickly restored to the humidified state. At this time, the time from when the absolute humidity becomes less than the humidification threshold to when it returns above the humidification threshold may be subtracted from the humidification time up to that point. When the supply of the bathtub water to the bathtub 1 is completed, the hot water supply controller C2 ends the combustion operation of the hot water supply side combustion unit 60, closes the hot water injection solenoid valve 68, and sends a control signal of the completion of the supply of the bathtub water to the bathtub 1 to the bathroom heating and drying controller C1 (steps S215 to S217). When the bathroom heating and drying controller C1 receives the control signal of the completion of the supply of the bathtub water to the bathtub 1 from the hot water supply controller C2 (Yes in step S55), the wrinkle removal control means 153 continues the above-described humidification determination. Note that the first replenishment temperature and the second replenishment temperature, and the supply amounts of the hot water thereof may be the same or different respectively.

[0058] When the humidification state where the absolute humidity is equal to or higher than the humidification threshold value continues for the humidification time (Yes in steps S52 and S53), the wrinkle removal control means 153 determines that the humidification has ended, and transmits a control signal to the drain plug controller C3 to open the automatic drain plug 12 (step S56). Then, the drain plug controller C3 opens the automatic drain plug 12 in response to the control signal (steps S303 to S304). As a result, the bathtub water is drained from the bathtub 1. At this time, the operation of the circulation fan 40 may be stopped.

[0059] Next, the wrinkle removal control means 153 executes a drying operation for a predetermined drying time (for example, 20 minutes) (step S60). This drying operation is the same as the drying operation when drying the above-mentioned clothes. Thereby, the clothes to which moisture has been attached for wrinkle removal can be dried. Although not shown, when the drying time has elapsed, the end of the wrinkle removal operation is notified from the display unit 109 and the speaker 110 of the remote controller 100.

[0060] According to the above embodiment, when the wrinkle removal operation mode is set by the remote controller 100, air is blown by the circulation fan 40 in the bathroom BR in a state where the bathtub water is stored in the bathtub 1, so that the bathtub water can be evaporated to humidify the entire bathroom BR. Therefore, according to the above embodiment, moisture can be evenly attached to the clothes by using the bathroom heater dryer 3 that does not have a mist generating means. Thereby, it is possible to efficiently remove wrinkles from a plurality of pieces of clothing at low cost.

[0061] Further, according to the above embodiment, the bathroom heating and drying machine 3 is connected to the hot water supply device 6. When the wrinkle removal operation mode is set by the remote controller 100, hot water is supplied from the hot water supply device 6 to the bathtub 1, so that the user does not need to directly supply the bathtub water to the bathtub 1. Therefore, the usability can be improved. Also, usually, since the user does not know the supply amount of the bathtub water suitable for humidifying the bathroom BR, there is a possibility that the bathtub 1 is supplied with bathtub water that is unnecessary for humidification. However, according to the above embodiment, the hot water supply device 6 can supply the bathtub 1 with the supply amount of bathtub water suitable for humidifying the bathroom BR, and the bathroom BR can be efficiently humidified.

[0062] Further, according to the above embodiment, when the initial room temperature in the bathroom BR is equal to or higher than the initial room temperature threshold value, water is supplied from the hot water supply device 6 to the bathtub 1 as bathtub water, so that the operation cost can be reduced. Also, according to the above embodiment, even if the room temperature in the bathroom BR is equal to or higher than the initial room temperature threshold value, if the water temperature of the water supplied from the hot water supply device 6 to the bathtub 1 is lower than the initial water temperature threshold value, hot water at the first start temperature is supplied from the hot water supply device 6 to the bathtub 1, so that the bathroom BR can be efficiently humidified.

[0063] On the other hand, when the room temperature in the bathroom BR is low, the amount of saturated water vapor is low, so it becomes difficult for the bathtub water to evaporate and it becomes difficult to humidify the bathroom BR. However, according to the above embodiment, when the room temperature in the bathroom BR is lower than the initial room temperature threshold value, the room temperature in the bathroom BR is raised by preliminary heating, so that the bathroom can be efficiently humidified. Also, according to the above embodiment, when the room temperature in the bathroom BR is lower than the initial room temperature threshold value, hot water at the second start temperature is supplied from the hot water supply device 6 to the bathtub 1, so that the bathroom BR can be more efficiently humidified.

[0064] Further, according to the above embodiment, when the increase amount of the absolute humidity within the increase amount determination time in the initial stage of the wrinkle removal operation is less than the increase amount threshold value, a warning message for notifying the user that the bathroom BR is in an environment where it is difficult to humidify is notified from the speaker 110 of the remote controller 100, so that the user can be made to check the bathroom BR at an early stage.

[0065] Further, according to the above embodiment, when the absolute humidity has not risen above the humidification threshold value when the initial determination time in the wrinkle removal operation has elapsed, hot water at the first replenishment temperature is supplied from the water supply device 6 to the bathtub 1, so that the bathroom BR can be humidified early.

[0066] Further, according to the above embodiment, after the absolute humidity has risen above the humidification threshold value, when the absolute humidity drops below the humidification threshold value, hot water at the second replenishment temperature is supplied from the water supply device 6 to the bathtub 1, so that the humidified state in the bathroom BR can be restored early.

[0067] Further, according to the above embodiment, when the absolute humidity has risen above the humidification threshold value when the initial determination time has elapsed, and after the elapse of the initial determination time, if the humidified state where the absolute humidity is above the humidification threshold value continues for the humidification time, the humidification in the bathroom BR is terminated, so that the user does not need to judge the humidified state in the bathroom BR. Therefore, the usability can be improved. Note that the relative humidity is the ratio of the amount of water vapor in the air to the saturated water vapor amount at a certain temperature, and the saturated water vapor amount decreases as the temperature decreases, so even if the relative humidity is high, the absolute humidity is low. On the other hand, since it is necessary to attach a certain amount of moisture to the clothes for wrinkle removal, it is necessary to make the amount of water vapor contained in the air equal to or more than a certain amount regardless of the temperature. Therefore, by judging the humidified state in the bathroom BR by the absolute humidity, it is possible to surely remove wrinkles from the clothes regardless of the temperature.

[0068] Further, according to the above embodiment, when the wrinkle removal operation mode is set, the drain port 11 is closed by the automatic drain plug 12, so the user does not need to close the drain plug of the bathtub 1. Therefore, the usability can be improved.

[0069] (Other Embodiments) (1) In the above embodiment, the bathtub water is supplied to the bathtub after the start of blowing by the blowing means. However, in the present invention, the blowing by the blowing means may be started during or after the supply of the bathtub water to the bathtub.

[0070] (2) In the above-described embodiment, in order to allow the user to check the bathroom environment at the start of the wrinkle removal operation, the notification means is used to notify the caution information. However, in the present invention, the presence or absence of the bathtub lid by the distance measuring sensor and the opening of the bathroom window or entrance by the mechanical switch are detected, and when it is detected by the detection means that the bathroom is in an environment where it is difficult to humidify, the caution information may be notified.

[0071] (3) In the above-described embodiment, an automatic drain valve is provided in the bathtub. However, in the present invention, a manual drain valve may be used. In this case, the opening of the manual drain valve may be notified from the notification means at the end of humidification. Further, in the above-described embodiment, the automatic drain valve is opened and closed by a control signal from the bathroom heater / dryer. However, when the automatic drain valve and the hot water supply device are connected, the automatic drain valve may be opened and closed by the hot water supply device. Also, the temperature and supply amount of the bathtub water supplied to the bathtub may be directly output to the bathroom heater / dryer.

[0072] (4) In the above-described embodiment, preheating is performed by supplying hot water from the hot water supply device to the bathroom heater / dryer. However, in the present invention, the bathroom heater / dryer may have a heating means independent of the hot water supply device.

[0073] (5) In the above-described embodiment, bathtub water is supplied to the bathtub without determining whether the bathtub is filled with hot water. However, if the bathtub water filled with hot water is used, the bathroom can be humidified. For this reason, when the wrinkle removal operation mode is set, before supplying the bathtub water to the bathtub, it may be determined whether the hot water filling operation has been performed or the automatic drain valve has been opened.

[0074] (6) In the above-described embodiment, in the wrinkle removal operation, the room temperature of the bathroom and the water temperature of the water that is the bathtub water are determined. However, in the present invention, in the wrinkle removal operation, the determination of the room temperature of the bathroom may be omitted.

[0075] (7) In the above embodiment, a bathroom heater / dryer is used as the bathroom device. However, in the present invention, a bathroom dryer or a bathroom heater may be used as the bathroom device.
