If the temperature difference between the temperature of the hot water (hot water) in the bathtub after bathing and the temperature of the bathroom is large, there is a risk of inducing a heat shock of the bather when the bather tries to bathe in the bathtub. be.

On the other hand, the temperature of the hot water that is poured into the bathtub by the hot water operation can generally be set variably as appropriate according to the wishes of the user. Then, in order to prevent the induction of heat shock, the preferable bathroom temperature changes according to the temperature of the hot water that is poured into the bathtub. For example, when the temperature of the hot water in the bathtub is high, the temperature of the bathroom which is preferable for preventing the induction of heat shock is higher than when the temperature of the hot water is low.

However, in the techniques found in Patent Documents 1 and 2, when the temperature of the bathroom at the beginning of the hot water filling is lower than the predetermined temperature, the hot water filling operation can be performed without considering the temperature of the hot water to be poured into the bathroom. The interlocking bathroom heating operation is executed.

Therefore, for example, when the temperature of the hot water to be poured into the bathtub is set to a relatively high temperature, the temperature difference between the temperature of the hot water in the bathtub and the temperature of the bathroom at the end of the hot water in the bathtub is large. There is a possibility that a large situation may occur, and in such a case, a heat shock of the bather may be induced.

Since the heating operation is performed, the temperature difference between the temperature of the hot water in the bathtub and the temperature of the bathroom after the completion of the hot water filling operation can be set to a size equal to or less than the predetermined value. Therefore, it is possible to prevent the temperature difference from becoming excessive.

Therefore, according to the present invention, when a bather who has entered the bathroom after the end of the bathing operation tries to take a bath in the bathtub, the bathing operation and the bathing operation and the induction of heat shock of the bather can be prevented as much as possible.

It is preferable to further include a bath operation control unit that controls the operation of the bath device so that hot water having a target temperature of the beam is poured into the bathtub.
Then, in addition to the basic configuration, the present invention is preset by the user as a command value of the temperature of the hot water to be poured into the bathtub when the heating operation is executed in conjunction with the execution of the hot water filling operation. When the hot water beam set temperature is higher than the predetermined temperature, the hot water beam target temperature lower than the hot water beam set temperature is determined, and the hot water beam target temperature is used instead of the hot water beam set temperature. Then, the operation of the bath device is controlled so that hot water having the target temperature of the hot water is poured into the bathtub, and when the set temperature of the hot water is lower than the predetermined temperature, it matches the set temperature of the hot water. It is characterized by further including a bath operation control unit that controls the operation of the bath device so that hot water having a target temperature of hot water is poured into the bathtub .

During the heating operation or drying operation of the bathroom BR, the air (warm air) heated through the heat exchanger by the heat of the heat generating part is blown into the bathroom BR by the operation of the ventilation fan. By operating the blower fan without operating the unit, it is possible to perform an operation operation such as blowing cool air to the bathroom BR.

The bathroom air conditioner main body 11 may be configured to be supplied with hot water heated by the heat source machine 2 of the bath water heater 1 instead of being provided with a heat generating unit. Alternatively, the heat generating portion of the bathroom air conditioner main body 11 may be a combustion type heat generating portion. Further, the bathroom air-conditioning main body 11 may be mounted on the wall of the bathroom BR.

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

The control device 8 of the heat source machine 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. Then, 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). Is configured to be able to do. In this case, in the present embodiment, the control device 8 includes a function as a bath operation control unit in the present invention.

For example, when the bathroom remote controller 3 starts the hot water filling operation of the bathtub BT, the bathroom air conditioner main unit 11 provides information indicating that fact, information indicating the hot water filling target temperature which is the target temperature of the hot water to be poured into the bathtub BT, and the like. Is transmitted to the control device 13.

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

Then, the control device 13 has the bathroom temperature indicated by the operation instruction information given from the bathroom air-conditioning operation remote controller 12 and the detection signal of the temperature sensor 14 by the functions realized by the mounted hardware configuration and program (software configuration). The operation of the bathroom air conditioner main body 11 can be controlled according to the detected value of the bathroom remote controller 3 or the information transmitted from the bathroom remote controller 3.

It may be configured so that communication can be performed wirelessly. Further, for example, the control device 8 of the heat source machine 2 and the control device 13 of the bathroom air conditioner main body 11 may be configured so that various information can be communicated by wire or wirelessly.

Further, the temperature sensor 14 may be arranged at a place other than the bathroom air-conditioning main body 11 as long as it can detect the bathroom temperature or a temperature that can be regarded as substantially the same as the bathroom temperature. For example, the temperature sensor 14 may be mounted on the bathroom remote controller 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.

Further, for example, the room temperature of the dressing room UDR can be considered to be substantially the same as the bathroom temperature before the bathtub BT is filled with hot water. Therefore, for example, when the remote control 12 for bathroom air-conditioning operation is equipped with a temperature sensor that detects the room temperature of the dressing room UDR, at the beginning of the hot water filling operation of the bathtub BT (at the start or at a time near the start). It is also possible to use the temperature detected by the temperature sensor as the bathroom temperature at the beginning of the hot water filling operation.

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

Next, the operation of the bathtub BT when hot water is applied will be described with reference to the flowcharts of FIGS. 2 and 3. In the following description, the control device 8 of the heat source machine 2 may be referred to as a bath / hot water supply 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 is instructed to execute the hot water operation by operating the bathroom remote controller 3 or the kitchen remote controller 4, or the user starts executing the hot water operation according to a schedule preset by the bathroom remote controller 3 or the kitchen remote controller 4. When a request to be made occurs, the bath / hot water supply control device 8 executes the process shown in the flowchart of FIG.

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

Here, in the heating / hot water beam automatic adjustment mode, in order to prevent the heat shock of the bather who enters the bathroom BR after the end of the hot water filling of the bathtub BT is induced, the bathroom BR is performed in parallel with the hot water filling operation. The heating target temperature of the bathroom BR (bathroom temperature due to the heating operation) so that the difference (absolute value) between the bathroom temperature realized when the heating operation of the bathtub BT is executed and the temperature of the hot water poured into the bathtub BT does not become too large. This is an operation mode that automatically adjusts the target value of. In the heating / hot water filling automatic adjustment mode, the temperature of the hot water filled in the bathtub BT is also adjusted as appropriate.

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

Next, in STEP 2, the bath / hot water supply control device 8 determines whether or not the heating / hot water temperature automatic adjustment mode is set to ON. If this determination result is negative, the bath / hot water supply control device 8 executes the hot water filling operation in STEP 10. In the hot water operation of STEP 10, the bath / hot water supply control device 8 heats hot water so as to match or substantially match the bath set temperature set in advance by the user by operating the bathroom remote control 3 or the kitchen remote control 4. The operation of the heat source machine 2 is controlled so that hot water is poured into the bathtub BT (the hot water is supplied from the heat source machine 2 to the bathtub BT via the bathtub pipe 7).

If the determination result of STEP2 is affirmative (when the heating / hot water temperature automatic adjustment mode is set to ON), the bath / hot water supply control device 8 sets the bath / hot water supply temperature (bathroom) in STEP3. It is determined whether or not the bath temperature preset by the user by operating the remote control 3 or the kitchen remote control 4 is a temperature equal to or higher than the first threshold temperature (for example, a temperature of 45 ° C. or higher), which is a relatively high temperature. ..

When the determination result of STEP 3 is affirmative (when the bath set temperature ≥ the first threshold temperature (45 ° C.)), the bath / hot water supply control device 8 sets the hot water filling target temperature (bathtub BT) in STEP 4. As the target temperature of the 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.

Further, when the determination result of STEP 3 is negative (when the bath set temperature <first threshold temperature (45 ° C.)), the bath / hot water supply control device 8 further sets the bath set temperature in STEP 5. It is determined whether or not the temperature is higher than the second threshold temperature (for example, 42 ° C), which is slightly lower than the first threshold temperature (45 ° C).

When the determination result of STEP 5 is positive (when the second threshold temperature (42 ° C) <bath set temperature <first threshold temperature (45 ° C)), the bath / hot water supply control device 8 , STEP6, a second threshold temperature (42 ° C.) is set as the hot water filling target temperature.

If the determination result of 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 keeps the bath set temperature as it is. Set as the beam target temperature.

From the above steps 3 to 7, when the bath set temperature is higher than the second threshold temperature (42 ° C), the hot water filling target temperature is within the range of the second threshold temperature (42 ° C) or higher, and the bath is set. 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 a temperature equal to or lower than the second threshold temperature (42 ° C.), the hot water filling target temperature is determined to be a temperature that matches the bath set temperature.

Here, when the hot water filling target temperature is higher than the second threshold temperature (42 ° C.), the bathroom temperature (≈ the 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 risk that the temperature will be too high compared to the temperature of the dressing room UDR as a room. In such a case, when a bather enters the bathroom BR from the dressing room UDR, there is a risk of inducing 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 filling target temperature is forcibly limited to a temperature lower than the bath set temperature.

Next, in STEP 8, the bath / hot water supply control device 8 causes the bathroom remote controller 3 to transmit the hot water beam target temperature determined as described above to the bathroom air conditioner main unit 11.

Further, in STEP 9, the bath / hot water supply control device 8 executes the hot water supply operation. In the hot water supply operation of STEP 9, the bath / hot water supply control device 8 fills the bathtub BT with hot water heated so as to match or substantially match the hot water supply target temperature determined as described above. Operates and controls.

The hot water filling operation is terminated when the hot water filling amount of the bathtub BT (integrated amount of hot water supplied to the bathtub BT) reaches a preset amount by the bathroom remote controller 3 or the kitchen remote controller 4.

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

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

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

Further, for example, the user specifies whether or not to allow the heating operation of the bathroom BR linked to the hot water operation by operating the bathroom remote control 3 or the kitchen remote control 4, or the bathroom air-conditioning operation remote control 12. In the case of obtaining, the execution condition of the heating operation may be satisfied when the heating operation of the bathroom BR linked to the hot water operation is permitted.

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

If the determination result of STEP 21 is affirmative (when the execution condition of the heating operation is satisfied), the bathroom air-conditioning control device 13 then turns on the heating / hot water temperature automatic adjustment mode in STEP 22. Whether or not it is set to is determined based on the operation information received from the bathroom remote controller 3.

If the determination result of STEP 22 is negative, the bathroom air-conditioning control device 13 executes the heating operation in STEP 28. In the heating operation of STEP 28, the bathroom air-conditioning control device 13 sets the bathroom temperature to the heating set temperature (set value of the bathroom temperature during the heating operation) set in advance by the user operating the bathroom air-conditioning operation remote control 12. By controlling one or both of the air volume of the air-conditioning fan of the bathroom air-conditioning main unit 11 (the air volume of warm air) and the heat-generating amount of the heat-generating unit so that the detected values of Operates. If the ventilation operation has been executed for 24 hours before the start of the heating operation, the ventilation operation is stopped and then the heating operation is started.

If the determination result of 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 controller 3 in STEP 23. Acquire the hot water beam target temperature (the hot water beam target temperature determined in STEP 4 or 6 or 7).

Then, in the bathroom air-conditioning control device 13, the temperature difference (= target temperature of hot water-heating set temperature) between the acquired target temperature of hot water and the set heating temperature set by the user is greater than a predetermined value (for example, 15 ° C.). It is judged in STEP24 whether or not the temperature is large.

The situation where the judgment result of STEP24 is affirmative is that, assuming that the heating operation in which the heating set temperature is the target of the bathroom temperature is executed in parallel with the bathing operation, the bathtub BT is filled with the hot water by the hot water operation. Since the temperature of the hot water (≈ target temperature for hot water) becomes too high compared to the bathroom temperature (≈ heating set temperature) warmed by the 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 for the bather.

Therefore, when the determination result of STEP 24 is affirmative (hot water target temperature-heating set temperature> predetermined value (15 ° C.)), the bathroom air conditioning control device 13 is set in STEP 25 during the heating operation. As the heating target temperature to be used as the actual target temperature of the bathroom temperature, a temperature lower than the above-mentioned predetermined value (15 ° C.) than the hot water beam target temperature is set.

If the determination result of STEP 24 is negative (target temperature of hot water-heating set temperature ≤ predetermined value (15 ° C.)), the bathroom air-conditioning control device 13 sets the heating set temperature in STEP 26. Set as the heating target temperature as it is.

By the above steps 24 to 26, the heating target temperature is determined so that the temperature difference from the hot water beam target temperature (= hot water beam target temperature-heating target temperature) is within the above-mentioned 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 matches or substantially matches the detected value of the bathroom temperature with the heating target temperature determined as described above. By controlling one or both of the amount of hot air blown) and the amount of heat generated by the heating unit, the operation of the bathroom air conditioning main unit 11 is controlled. If the ventilation operation is executed for 24 hours before the start of the heating operation, the ventilation operation is stopped and then the heating operation is started.

In the present embodiment, when the hot water supply operation is started, the control processes of the bath / hot water supply control device 8 and the bathroom air conditioning control device 13 are jointly executed as described above. As a result, when the hot water filling 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 filling 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 the temperature difference from the hot water temperature target temperature ( = Hot water beam target temperature-Heating target temperature) is determined to be within a predetermined value (15 ° C) or less. Therefore, when a bather who has entered the bathroom BR bathes in the bathtub BT after the end of the hot water filling operation, the bathroom temperature (≈heating target temperature) and the temperature of the hot water in the bathtub BT (≈ hot water filling target temperature). It is prevented that the temperature difference between the bath and the bath is excessive. As a result, the bather can prevent the bather from inducing heat shock when taking a bath.

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

Therefore, it is possible to prevent the bather from inducing heat shock when the bather enters the bathroom BR from the dressing room UDR after the bathing operation is completed.

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

Further, in the above embodiment, when the temperature difference between the heating set temperature by the user and the hot water filling target temperature is not more than a predetermined value (15 ° C.), the heating set temperature is set as the heating target temperature as it is. However, for example, the heating target temperature may be set independently of the heating set temperature within a range in which the temperature difference between the heating target temperature and the hot water filling target temperature is within a predetermined value.

Further, the bath device in the present invention may be a device having no hot water supply function.
