  In addition, the bathroom air-conditioning main-body part 11 may be comprised so that the warm water heated with the heat-source equipment 2 of the bath hot-water supply apparatus 1 may be supplied instead of providing a heat generating part. Alternatively, the heat generating part of the bathroom air-conditioning main body 11 may be a combustion type heat generating part. Moreover, the bathroom air-conditioning main-body part 11 may be mounted on the wall of the bathroom BR.

  Further, the heat source device 2 is equipped with a control device 8 that controls the operation of the heat source device 2, and the bathroom air conditioning main body 11 is equipped with a control device 13 that controls the operation of the bathroom air conditioning main body 11. In addition, a temperature sensor 14 for detecting the room temperature of the bathroom BR (hereinafter referred to as bathroom temperature) is mounted. The control devices 8 and 13 are each composed of an electronic circuit unit including a CPU, a RAM, a ROM, an interface circuit and the like.

  The control device 8 of the heat source device 2 is connected to each of the bathroom remote controller 3 and the kitchen remote controller 4 so as to be able to perform wired communication with the bathroom remote controller 3 and the kitchen remote controller 4. The control device 8 controls the operation of the heat source unit 2 according to the operation instruction information given from the bathroom remote controller 3 or the kitchen remote controller 4 by the functions realized by the implemented hardware configuration and program (software configuration). It is comprised so that it can perform. In this case, in the present embodiment, the control device 8 includes a function as a bath operation control unit in the present invention.

  Moreover, in this embodiment, the bathroom remote control 3 is comprised so that the operation information etc. of the bath water heater 1 can be suitably transmitted to the control apparatus 13 of the bathroom air-conditioning main-body part 11 by radio | wireless communications, such as infrared communication. . For example, when the bathroom remote controller 3 starts the hot water operation of the bathtub BT, the bathroom air conditioning main body 11 displays information indicating that, information indicating the hot water target temperature that is the target temperature of hot water to be poured into the bathtub BT, and the like. To the control device 13.

  The control device 13 of the bathroom air-conditioning main body 11 is connected to the remote control 12 so as to be able to perform wired communication with the bathroom air-conditioning operation remote control 12. Further, the control device 13 receives a detection signal from the temperature sensor 14 (a detection signal indicating the bathroom temperature), information transmitted from the bathroom remote controller 3, and the like.

  Then, the control device 13 uses the functions realized by the implemented hardware configuration and program (software configuration), the operation instruction information given from the bathroom air-conditioning operation remote controller 12, and the bathroom temperature indicated by the detection signal of the temperature sensor 14. The operation control of the bathroom air-conditioning main body 11 can be performed in accordance with the detected value or information transmitted from the bathroom remote controller 3 or the like.

You may be comprised so that communication can be performed by radio | wireless. In addition, for example, various types of information may be configured to be communicated between the control device 8 of the heat source device 2 and the control device 13 of the bathroom air-conditioning main body 11 by wire or wireless.

  Further, the temperature sensor 14 may be disposed at a place other than the bathroom air-conditioning main body 11 as long as it can detect a bathroom temperature or a temperature that can be regarded as substantially equivalent to the bathroom temperature. For example, the temperature sensor 14 may be mounted on the bathroom remote control 3. In this case, the control device 13 can acquire the detected value of the bathroom temperature by transmitting information from the bathroom remote controller 3 to the control device 13 of the bathroom air-conditioning main body 11.

  In addition, for example, before the hot water of the bathtub BT, the room temperature of the dressing room UDR can be considered to substantially match the bathroom temperature. Therefore, for example, when the temperature sensor for detecting the room temperature of the dressing room UDR is mounted on the remote controller 12 for the air conditioning operation of the bathroom, at the beginning of the hot water operation of the bathtub BT (at the time of starting or in the vicinity thereof). It is also possible to use the temperature detected by the temperature sensor as the bathroom temperature at the beginning of hot water operation.

  Further, the control device 8 of the heat source device 2 and the control device 13 of the bathroom air-conditioning main body 11 can be integrated and configured.

  Next, with reference to the flowchart of FIG.2 and FIG.3, the operation | movement in the case of performing the hot water of the bathtub BT is demonstrated. In the following description, the control device 8 of the heat source device 2 may be referred to as a bath / hot water control device 8, and the control device 13 of the bathroom air conditioning main body 11 may be referred to as a bathroom air conditioning control device 13.

  When the user instructs the execution of the hot water operation by operating the bathroom remote control 3 or the kitchen remote control 4, or starts the execution of the hot water operation according to a schedule preset by the user with the bathroom remote control 3 or the kitchen remote control 4. When a request to be generated is generated, the bath / hot-water supply control device 8 executes the processing shown in the flowchart of FIG.

  First, in STEP 1, the bath / hot water control device 8 uses heating / hot water as the hot water operation start information indicating the start of hot water operation and the operation modes of the bath hot water device 1 and the bathroom air conditioner 10 during hot water operation. The operation mode information indicating whether or not the beam temperature automatic adjustment mode is set to the valid state (ON) is transmitted from the bathroom remote controller 3 to the bathroom air conditioning main body 11.

  Here, in the heating / hot water automatic adjustment mode, in order to prevent the heat shock of the bather entering the bathroom BR after the hot water of the bathtub BT is finished, the bathroom BR is performed in parallel with the hot water operation. So that the difference (absolute value) between the bathroom temperature realized when the heating operation is performed and the temperature of the hot water poured into the bathtub BT is not so large (the bathroom temperature by the heating operation) The target mode is automatically adjusted. In the heating / hot water automatic adjustment mode, the temperature of hot water to be poured into the bathtub BT is also adjusted as appropriate.

  In this embodiment, when the user operates the bathroom remote controller 3 or the kitchen remote controller 4 in advance, the heating / hot water temperature automatic adjustment mode is turned on / off to the bath / hot water control device 8. It is possible to select and set in advance.

  Next, in STEP 2, the bath / hot water control device 8 determines whether or not the heating / hot water temperature automatic adjustment mode is set to ON. When this determination result is negative, the bath / hot water supply control device 8 executes a hot water operation in STEP 10. In the hot water operation of STEP 10, the bath / hot water control device 8 uses hot water heated so as to match or substantially match the bath set temperature set in advance by operating the bathroom remote controller 3 or the kitchen remote controller 4. Operation control of the heat source device 2 is performed so that hot water is poured into the bathtub BT (the hot water is supplied from the heat source device 2 to the bathtub BT via the bathtub piping 7).

  When the determination result in STEP 2 is affirmative (when the heating / hot water temperature automatic adjustment mode is set to ON), the bath / hot water control device 8 determines the bath set temperature (bathroom) in STEP 3. It is determined whether or not the bath temperature set in advance by the user by operating the remote controller 3 or the kitchen remote controller 4 is a temperature higher than a first threshold temperature that is a relatively high temperature (for example, a temperature of 45 ° C. or higher). .

  When the determination result in STEP 3 is affirmative (when the bath set temperature ≧ first threshold temperature (45 ° C.)), the bath / hot water supply control device 8 determines the hot water target temperature (bath BT BT) in STEP 4. As a target temperature of hot water that is actually poured, a temperature that is lower than the bath set temperature by a predetermined value (for example, 3 ° C.) is set.

  When the determination result of STEP 3 is negative (when the bath set temperature <the first threshold temperature (45 ° C.)), the bath / hot water supply controller 8 further determines that the bath set temperature is It is determined whether the temperature is higher than a second threshold temperature (for example, 42 ° C.) that is slightly lower than the first threshold temperature (45 ° C.).

  When the determination result of STEP 5 is affirmative (when the second threshold temperature (42 ° C.) <Bath set temperature <first threshold temperature (45 ° C.)), the bath / hot water control device 8 In STEP 6, the second threshold temperature (42 ° C.) is set as the hot water target temperature.

  When the determination result in STEP 5 is negative (when the bath set temperature ≦ the second threshold temperature (42 ° C.)), in STEP 7, the bath / hot water supply control device 8 uses the bath set temperature as it is. Set as beam target temperature.

  When the bath setting temperature is higher than the second threshold temperature (42 ° C.), the hot water target temperature is within the range equal to or higher than the second threshold temperature (42 ° C.). It is determined to be a temperature lower than the temperature (bath set temperature-3 ° C. or second threshold temperature (42 ° C.)). When the bath set temperature is equal to or lower than the second threshold temperature (42 ° C.), the hot water target temperature is determined to be a temperature that matches the bath set temperature.

  Here, when the hot water target temperature is higher than the second threshold temperature (42 ° C.), the bathroom temperature (≈ heating target temperature described later) realized by the heating operation of the bathroom BR described later is adjacent to the bathroom BR. There is a possibility that the temperature becomes too high as compared with the temperature of the dressing room UDR as a room. In such a case, when the bather enters the bathroom BR from the dressing room UDR, there is a risk of inducing a heat shock of the bather. Therefore, in the present embodiment, when the bath set temperature is higher than the second threshold temperature (42 ° C.), the hot water target temperature is forcibly limited to a temperature lower than the bath set temperature.

  Next, in STEP 8, the bath / hot water control device 8 transmits the hot water target temperature determined as described above from the bathroom remote controller 3 to the bathroom air conditioning main body 11.

  Further, in STEP 9, the bath / hot water control device 8 executes hot water operation. In this hot water operation of STEP 9, the bath / hot water control device 8 heats the hot water source 2 so that hot water heated to match or substantially matches the hot water target temperature determined as described above is poured into the bathtub BT. The operation control is performed.

  The hot water operation is terminated when the hot water amount of the bathtub BT (the accumulated amount of hot water supplied to the bathtub BT) reaches the amount set in advance by the bathroom remote controller 3 or the kitchen remote controller 4.

  On the other hand, when receiving the hot water operation start information and the operation mode information transmitted from the bathroom remote controller 3 in STEP 1, the bathroom air-conditioning control device 13 executes the process shown in the flowchart of FIG. 3.

  In this case, first, in STEP 21, the bathroom air-conditioning control device 13 determines whether or not an execution condition for heating operation of the bathroom BR (necessary condition for executing the heating operation) is satisfied. In the present embodiment, for example, when the detection value of the bathroom temperature (the detection value of the bathroom temperature at the beginning of the hot water operation) indicated by the detection signal of the temperature sensor 14 is equal to or lower than a predetermined temperature (for example, 15 ° C.). The execution condition of the heating operation is established.

  The predetermined temperature may be variably set by the user by operating the remote control 12 for bathroom air conditioning operation. Alternatively, the predetermined temperature may be variably set by the bathroom air-conditioning control device 13 according to environmental conditions such as season or temperature.

  Further, for example, the user designates whether to permit the heating operation of the bathroom BR linked to the hot water operation by operating the bathroom remote controller 3 or the kitchen remote controller 4 or the bathroom air conditioner operation remote controller 12. In the case of obtaining the heating operation, the condition for performing the heating operation may be satisfied when it is permitted to perform the heating operation of the bathroom BR linked to the hot water operation.

  When the determination result in STEP 21 is negative (when the heating operation execution condition is not satisfied), the processing of the bathroom air-conditioning control device 13 ends (the heating operation is not executed).

  If the determination result in STEP 21 is affirmative (when the heating operation execution condition is satisfied), the bathroom air-conditioning control device 13 next turns on the heating / hot water temperature automatic adjustment mode in STEP 22. Is determined based on the driving information received from the bathroom remote controller 3.

  When the determination result in STEP 22 is negative, the bathroom air-conditioning control device 13 executes the heating operation in STEP 28. In the heating operation in STEP 28, the bathroom air-conditioning control device 13 sets the bathroom temperature to the heating preset temperature (the set value of the bathroom temperature during the heating operation) set in advance by the user operating the remote controller 12 for bathroom air-conditioning operation. By controlling one or both of the air volume of the blower fan of the bathroom air-conditioning main body 11 (warm air flow rate) and the heat generation amount of the heat generating part so that the detected values match or substantially coincide with each other, the bathroom air-conditioning main body 11 The operation control is performed. In addition, when the ventilation operation is performed for 24 hours before the heating operation is started, the heating operation is started after the ventilation operation is stopped.

  When the determination result in STEP 22 is affirmative (when the heating / hot water temperature automatic adjustment mode is set to ON), the bathroom air-conditioning control device 13 is transmitted from the bathroom remote control 3 in STEP 23. The hot water target temperature (the hot water target temperature determined in STEP 4 or 6 or 7) is acquired.

  And the control apparatus 13 for bathroom air-conditioning has the temperature difference (= hot water target temperature-heating setting temperature) of the acquired hot water target temperature and the heating preset temperature set by the user from predetermined value (for example, 15 degreeC). It is determined in STEP 24 whether or not is larger.

  The situation in which the determination result in STEP 24 is affirmative is that when it is assumed that the heating operation in which the heating set temperature is the target of the bathroom temperature is performed in parallel with the hot water operation, the hot water operation is performed on the bathtub BT. Since the temperature of the heated water (≒ hot water target temperature) becomes too high compared to the bathroom temperature (≒ heating set temperature) warmed by heating operation, the bather who entered the bathroom BR takes a bath in the bathtub BT When this happens, there is a risk of inducing a heat shock of the bather.

  Therefore, if the determination result in STEP 24 is affirmative (the hot water target temperature−the heating set temperature> the predetermined value (15 ° C.)), the bathroom air-conditioning control device 13 determines in STEP 25 that the heating operation is being performed. As the heating target temperature used as the actual target temperature of the bathroom temperature, a temperature lower than the hot water target temperature by the predetermined value (15 ° C.) is set.

  In addition, when the determination result of STEP 24 is negative (hot water target temperature−heating setting temperature ≦ predetermined value (15 ° C.)), the bathroom air-conditioning control device 13 sets the heating setting temperature in STEP 26. Set the heating target temperature as it is.

  Through the processing of STEPs 24 to 26, the heating target temperature is determined such that the temperature difference from the hot water target temperature (= hot water target temperature−heating target temperature) falls within the predetermined value (15 ° C.).

  After determining the heating target temperature in this way, the bathroom air-conditioning control device 13 executes the heating operation in STEP 27. In the heating operation of STEP 27, the bathroom air-conditioning control device 13 sets the air flow rate of the blower fan of the bathroom air-conditioning main body 11 so that the detected value of the bathroom temperature matches or substantially matches the heating target temperature determined as described above. The operation control of the bathroom air-conditioning main body 11 is performed by controlling one or both of the hot air flow rate) and the heat generation amount of the heat generation unit. In addition, when the ventilation operation is performed for 24 hours before the heating operation is started, the heating operation is started after the ventilation operation is stopped.

  In the present embodiment, when hot water operation is started, the control processing of the bath / hot water control device 8 and the bathroom air conditioning control device 13 is executed in cooperation as described above. Thereby, if the hot water operation is started in a state where the execution condition of the heating operation is satisfied, the heating operation of the bathroom BR is automatically executed in parallel with the hot water operation.

  In this case, when the heating / hot water temperature automatic adjustment mode is set to ON, the heating target temperature as the target value of the bathroom temperature actually used in the heating operation is different from the hot water target temperature ( (= Hot water target temperature−heating target temperature) is determined to be equal to or less than a predetermined value (15 ° C.). For this reason, when a bather entering the bathroom BR takes a bath in the bath BT after the hot water operation is finished, the bath temperature (≈heating target temperature) and the temperature of hot water in the bath BT (≈ hot water target temperature) It is prevented that the temperature difference between and is excessive. As a result, when the bather takes a bath, the bather can prevent the heat shock of the bather from being induced.

  Further, when the bath set temperature set by the user is higher than the second temperature threshold (42 ° C.), the hot water target temperature is forcibly set as the target value of the temperature of the hot water actually applied to the bathtub BT. In addition, the temperature is set lower than the bath set temperature. As a result, the heating target temperature in the heating operation performed in parallel with the hot water operation is prevented from becoming too high with respect to the temperature of the dressing room UDR (the room adjacent to the bathroom BR).

  For this reason, when the bather enters the bathroom BR from the dressing room UDR after the hot water operation is completed, it is possible to prevent the heat shock of the bather from being induced.

  In the embodiment described above, the control process shown in the flowchart of FIG. 2 is executed by the bath / hot-water supply control device 8 and the control process shown in the flowchart of FIG. 3 is executed by the bathroom air-conditioning control device 13. I made it. However, for example, when the bath / hot water control device 8 and the bathroom air-conditioning control device 13 can communicate with each other, a part of the control processing shown in the flowchart of FIG. Alternatively, a part of the control process shown in the flowchart of FIG. 3 can be executed by the bath / hot water control device 8.

  Moreover, in the said embodiment, when the temperature difference of the heating preset temperature by a user and the hot water target temperature is below a predetermined value (15 degreeC), heating preset temperature was set as heating target temperature as it is. However, for example, the heating target temperature may be set without depending on the heating set temperature within a range in which the temperature difference between the heating target temperature and the hot water target temperature falls within a predetermined value.

  Further, the bath apparatus in the present invention may be an apparatus that does not have a hot water supply function.
