The signal generation unit 136 generates a water mist preparation operation signal as will be described later based on the determination results of the forward temperature determination unit 130 and the mist temperature determination unit 132 during the water mist operation.

  In addition, the condition relaxation signal generation unit 138 generates a condition relaxation signal as described later when the cool breeze preparation operation continues or when the water mist preparation operation continues. The operation switching signal generation means 140 will be described later when the environmental state suitable for the cool wind operation is reached during the cool wind preparation operation, and when the environmental state suitable for the water mist operation is reached during the water mist preparation operation. A relaxed condition signal is generated. The abnormal signal generation unit 142 generates an abnormal signal as will be described later.

  The controller 92 further includes timing means 144 and memory means 146. The time measuring means 144 measures time as will be described later. Further, various data are registered in the memory means 146, and a first set forward temperature T1 (for example, set to around 50 ° C.) and a second set forward temperature T2 (the first set temperature) that serve as the judgment reference of the forward temperature judgment means 130. The temperature is higher than the set outgoing temperature M1 and is set to, for example, about 55 ° C.), the first set mist temperature M1 (for example, set to about 60 ° C.) and the first reference mist temperature determination means 132 2 set mist temperature M2 (a temperature higher than the first set mist temperature M1 and set to, for example, around 65 ° C.), and a first set time t1 (for example, 5 minutes) related to the cool air preparation operation and the water mist preparation operation And the second set time t2 (for example, set to about 5 minutes) and the like are registered.

  In this embodiment, as will be described later, for the cool air preparatory operation, there is a first cool air preparatory operation and a second cool air preparatory operation performed thereafter, and the first cool air preparatory operation is based on the first set outgoing temperature T1. In the second cool breeze preparatory operation, the determination is made based on conditions that are more relaxed than in the first cool breeze preparatory operation, that is, the second set forward temperature T2. As for the water mist preparation operation, there are a first water mist preparation operation and a second water mist preparation operation performed thereafter. In the first water mist preparation operation, the first set forward temperature T1 and the first set mist M1. In the second cool breeze preparatory operation, the conditions are more relaxed than in the first cool breeze preparatory operation, that is, based on the second set forward temperature T2 and the second set mist temperature M2.

  In this bathroom heater / dryer, cool air operation is performed as follows. Referring mainly to FIG. 2, FIG. 4 and FIG. 5, in order to perform the cool wind operation, the cool air switch 102 of the operation remote controller 93 may be turned on (step S1). A display to that effect is performed, and a cool wind operation described later is performed for a preset time. In addition, what is necessary is just to input operation of the time setting switch 114, when changing this operation time.

  When the input operation is performed in this way, the time measuring unit 144 of the controller 92 measures the time (step S2), and then the heating temperature is detected (step S3). This temperature detection is performed by the hot water going-out temperature detecting means 84, a detection signal from the hot water going-out temperature detecting means 84 is sent to the controller 92, and the going-out temperature determining means 130 determines that the detected temperature T is the first set outgoing temperature T1. It is determined whether or not (for example, 50 ° C.) or less. For example, immediately after the heating operation (or drying operation, splash mist operation, micro mist operation), when hot water remains in the heating heat exchanger 8 of the heating dryer body 2 and the circulation fan 10 is operated, the heating heat There is a risk that the warm air heat-exchanged by the exchanger 8 will blow out from the outlet. For this reason, if the detected temperature T of the warm water going temperature detecting means 84 exceeds the first set going temperature T1 (T> T1), there is a possibility that warm air may blow out from the main body 2 of the heating dryer. From S4, the process proceeds to step S5. On the other hand, if the detected temperature T is equal to or lower than the first set outgoing temperature T1 (T ≦ T1), the process proceeds from step S4 to step S6 on the assumption that there is no risk of the hot air blowing from the heating / drying machine body 2. The cool air operation of the bathroom heater / dryer is started.

  When the detected temperature of the warm water going temperature detection means 84 exceeds the first set going temperature T1 (T> T1), the cool wind preparation operation signal generating means 134 is based on the determination result of the going temperature determination means 130, and the cool wind preparation operation signal is generated. (In this embodiment, a first cool air preparation operation signal) is generated, and the bathroom heater / dryer is operated with a cool air preparation operation (first cool air preparation operation) based on the cool air preparation operation signal (step S5). In this cool breeze preparatory operation, the ventilation fan 34 of the heating / drying machine body 2 is operated, and the air in the bathroom is sucked from the suction port 18 and then exhausted through the circulation channel 4 and the ventilation channel 6 (not shown). ) To the outside, thus ventilating the bathroom (step S7), and warm air in the bathroom is discharged to the outside through the ventilation channel 6. At this time, the heating heat exchanger 8 is cooled by the air flowing through the circulation flow path 4, and the heating-out temperature decreases. This preparatory operation signal is transmitted from the controller 92 to the operation remote controller 93, and the display means 124 displays that the cool air preparatory operation is being performed, and the user is in the cool air preparatory operation by viewing the display. Can be easily known.

  During this cool breeze preparatory operation (first cool breeze preparatory operation), temperature detection is performed by the warm water going-out temperature detecting means 84 (step S8), and the detected temperature T is lowered to the first set outgoing temperature T1 or less (T ≦ T1), the process proceeds from step S9 to step S10, and the forward temperature determination means 130 determines that the forward temperature of the heat exchanger 8 for heating is lowered and there is no risk of warm air blowing, and based on this determination result, the ventilation fan 34 is deactivated. In addition, the operation switching signal generating means 140 generates an operation switching signal, and the operation is switched based on the operation switching signal (step S11), and the cool air preparation operation (first cool air preparation operation) is completed and the cool air operation is completed. Is started (step S6). This operation switching signal is transmitted to the operation remote controller 93, and the display of the cool air preparation operation on the display means 124 disappears.

  When this cool breeze preparatory operation (first cool breeze preparatory operation) is continuously performed for the first set time t1 (for example, 5 minutes), the process proceeds from step S9 to step S12 to step S13, and the condition relaxation signal generation means 138 sets the condition. A relaxation signal is generated, and based on the condition relaxation signal, a condition relaxation operation (second cool air preparation operation) of the bathroom heater / dryer is performed. In the condition relaxation operation, the temperature is determined by switching from the first set forward temperature T1 (for example, 50 ° C.) to the second set forward temperature T2 (for example, 55 ° C.).

  During this condition relaxation operation (second cool breeze preparatory operation), temperature detection is performed by the hot water going-out temperature detecting means 84 (step S14), and the detected temperature T is lowered to the second set outgoing temperature T2 or less (T ≦ T2), the process proceeds from step S15 to step S16, and the outgoing temperature determination means 130 determines that the outgoing temperature of the heat exchanger 8 for heating is lowered to some extent and the interior of the bathroom is ventilated to obtain a cool wind feeling. Based on this, the ventilation fan 34 is deactivated. Further, as described above, the operation switching signal generation means 140 generates an operation switching signal, and the operation is switched based on this operation switching signal (step S17), and the condition relaxation operation (second cool air preparation operation). Is finished and the cool wind operation is started (step S6), and the display of the cool wind preparation operation on the display means 124 of the operation remote controller 93 disappears.

  If this condition relaxation operation (second cool breeze preparation operation) is continuously performed for the second set time t2 (for example, 5 minutes), the process proceeds from step S15 to step S18 to step S19. As the going-out temperature of the heat exchanger 8 does not decrease and there is a possibility that some abnormality has occurred in the bathroom heater / dryer, the abnormal signal generating means 142 generates an abnormal signal (step S19), and based on this abnormal signal. Then, the operation of the bathroom heater / dryer is stopped (that is, the ventilation fan 4 is stopped).

  When the cool air operation of the bathroom heater / dryer is started in step S6, the louver motor 32 of the heater / dryer main body 2 is operated to swing the louver 28 (step S21), and the circulation fan 10 is operated (step S22). Further, the ventilation fan 34 is actuated (step S23), the air sucked through the suction port 18 of the heating dryer body 2 blows out from the blowout port 20, and a part of the air in the bathroom is recirculated through the circulation channel 4 and The air is discharged to the outside through the ventilation channel 6, and the bathroom becomes a space where a cool breeze can be obtained.

  If the stop switch 108 of the operation remote controller 93 is turned on during the cool wind operation (or the set time for performing the cool wind operation elapses), the process proceeds from step S24 to step S25, the louver motor 32 stops operating, and the circulation fan 10 Is deactivated (step S26), and the ventilation fan 34 is deactivated (step S27). Thus, the cool air operation of the bathroom heater / dryer is completed (step S28). When the operation is finished in this way, an operation end signal is transmitted to the operation remote controller 93, and the cool wind operation display on the display means 124 disappears.

  In this embodiment, the condition relaxation operation (second cool wind preparation operation) is performed after the cool wind preparation operation (first cool wind preparation operation). However, this condition relaxation operation may be omitted. Even if the preparatory operation (first cool breeze preparatory operation) is continuously performed for the first set time t1, the abnormal signal is generated when the forward temperature of the heating heat exchanger 8 exceeds the first forward temperature T1 (T> T1). The generation unit 142 generates an abnormal signal.

  Next, the water mist operation of the bathroom heating dryer described above will be described. Referring mainly to FIG. 2, FIG. 4 and FIG. 6, in order to perform the water mist operation, the water mist switch 107 of the operation remote controller 93 may be turned on (step S31). Display of mist operation is performed, and water mist operation described later is performed for a preset time.

  When the input operation is performed in this manner, the time measuring unit 144 of the controller 92 measures the time (step S32), subsequently the heating forward temperature is detected (step S33), and the mist temperature is further detected (step S34). . This forward temperature detection is performed by the warm water forward temperature detection means 84, and the mist temperature detection is performed by the mist warm water temperature detection means 88, and detection signals from these temperature detection means 84, 88 are sent to the controller 92.

  In this water mist operation, the forward temperature determination means 130 detects that the detected temperature T of the warm water forward temperature detection means 84 is equal to or lower than the first preset forward temperature T1 (for example, 50 ° C.) (T ≦ T1) and detects the mist warm water temperature. It is determined whether the detected temperature M of the means 88 is equal to or lower than the first set mist temperature M1. For example, immediately after the heating operation (or drying operation, splash mist operation, micro mist operation), when hot water remains in the heating heat exchanger 8 of the heating dryer body 2 and the circulation fan 10 is operated, the heating heat There is a possibility that the hot air heat-exchanged in the exchanger 8 may blow out from the outlet, and immediately after the splash mist operation (or micro mist operation), the mist heat exchanger 54 and the drain line 66 of the mist generator 52 are provided. There is a possibility that the hot water remains in a part of the mist line and the splash mist line 68, and the hot water may be ejected from the splash mist generating nozzle 56 through the splash mist line 68.

  For this reason, if the detected temperature T of the warm water going temperature detecting means 84 exceeds the first set going temperature T1 (T> T1), there is a possibility that hot air may blow out from the heating dryer body 2, and If the detected temperature M of the mist hot water temperature detecting means 88 exceeds the first set mist temperature M1 (M> M1), it is assumed that hot water may be ejected from the splash mist generating nozzle 56. In these cases, from step S35 Proceed to step S36. On the other hand, the detected temperature T of the warm water going temperature detecting means 84 is not more than the first set going temperature T1 (T ≦ T1), and the detected temperature M of the mist hot water temperature detecting means 88 is not more than the first set mist temperature M1 (M ≦ M1), it is determined that there is no possibility that hot air will blow out from the heating / drying machine main body 2 and that there is no possibility that hot water will be sprayed from the splash mist generating nozzle 56, and the process proceeds from step S35 to step S37. Operation starts.

  When the detected temperature T of the warm water going temperature detecting means 84 exceeds the first set going temperature T1 (T> T1), the water mist preparation operation signal generating means 136 is based on the determination result of the going temperature determining means 130, When a preparation operation signal (in this embodiment, a first water mist preparation operation signal) is generated and the detected temperature M of the mist hot water temperature detecting means 88 exceeds the first set mist temperature M1 (M> M1), the mist Based on the determination result of the temperature determination unit 132, the water mist preparation operation signal generation unit 136 similarly generates a water mist preparation operation signal (in this embodiment, a first water mist preparation operation signal). Then, based on the water mist preparation operation signal, the bathroom heater / dryer is operated as a water mist preparation operation (first water mist preparation operation) (step S36).

  In this water mist preparatory operation, the ventilation fan 34 of the heating / drying machine main body 2 is operated, and the air in the bathroom is ventilated in the same manner as described above (step S38). In addition, the heating heat exchanger 8 is cooled by the air that is discharged to the outside through the ventilation flow path 6 and flows through the circulation flow path 4, and the heating-out temperature is lowered. This water mist preparation operation signal is transmitted to the operation remote controller 93, and the display means 124 displays the water mist preparation operation.

  During this water mist preparatory operation (first water mist preparatory operation), the hot water forward temperature detecting means 84 detects the hot water forward temperature (step S39), and the mist hot water temperature detecting means 88 detects the mist hot water temperature. (Step S40), the detected temperature T of the hot water going-out temperature detecting means 84 is lowered to the first set outgoing temperature T1 or less (T ≦ T1), and the detected temperature M of the mist hot water temperature detecting means 88 is set to the first setting. When the temperature decreases to the mist temperature M1 (M ≦ M1), the process proceeds from step S41 to step S42, and the forward temperature determination unit 130 determines that the forward temperature of the heating heat exchanger 8 is decreased and there is no possibility that the warm air is blown out. Further, the mist temperature determining means 132 determines that there is no possibility that the mist temperature is lowered and hot water is ejected from the splash mist generating nozzle 56. Ventilation fan 34 is deactivated based on the results. Further, the operation switching signal generating means 140 generates an operation switching signal, and the operation is switched based on the operation switching signal (step S43), and the water mist preparation operation (first water mist preparation operation) is completed, Water mist operation is started (step S37). This operation switching signal is transmitted to the operation remote controller 93 and the display of the water mist preparation operation on the display means 124 disappears.

  When this water mist preparation operation (first water mist preparation operation) is continuously performed for the first set time t1 (for example, 5 minutes), the process proceeds from step S41 to step S44 to step S45, and the condition relaxation signal generation unit 138 is performed. Generates a condition relaxation signal, and the condition relaxation operation (second water mist preparation operation) of the bathroom heater / dryer is performed based on the condition relaxation signal. In this condition relaxation operation, the first set forward temperature T1 (for example, 50 ° C.) is switched to the second set forward temperature T2 (for example, 55 ° C.) to determine the forward hot water temperature, and the first set mist The temperature is switched from the temperature M1 (for example, 60 ° C.) to the second set mist temperature M2 (for example, 65 ° C.), and the mist hot water temperature is determined.

  During this condition relaxation operation (second cool air preparatory operation), the warm water temperature detection means 84 detects the warm water temperature (step S46), and the mist warm water temperature detection means 88 detects the mist warm water temperature. (Step S47), the detected temperature T of the forward hot water is lowered to the second preset outgoing temperature T2 or less (T ≦ T2), and the detected temperature M of the mist hot water is lowered to the second preset mist temperature M2 or lower (M ≦ M2), the process proceeds from step S48 to step S49, where the forward temperature determining means 130 determines that the forward temperature of the heat exchanger 8 for heating has been reduced to some extent, and the mist temperature determining means 132 is that of the mist generating means 55. It is determined that the temperature of the mist warm water has decreased to some extent, and the ventilation fan 34 is deactivated based on these determination results. Further, as described above, the operation switching signal generation means 140 generates an operation switching signal, and the operation is switched based on this operation switching signal (step S50), and the condition relaxation operation (second water mist preparation operation). ) Is finished, and the water mist operation is started (step S37), and the display of the water mist preparation operation on the display means 124 of the operation remote controller 93 disappears.

  If this condition relaxation operation (second water mist preparation operation) is continuously performed for the second set time t2 (for example, 5 minutes), the process proceeds from step S48 to step S51 to step S52, and heating is performed even after a predetermined time has elapsed. The forward signal of the heat exchanger 8 and the mist temperature of the mist generating means 55 are not lowered, and there is a possibility that some abnormality has occurred in the bathroom heater / dryer, so that the abnormal signal generating means 142 generates an abnormal signal ( In step S52), the operation of the bathroom heater / dryer is stopped based on the abnormal signal (step S53).

  When the water mist operation of the bathroom heating / drying machine is started in step S37, the louver motor 32 of the heating / drying machine body 2 is operated to swing the louver 28 (step S54), and the circulation fan 10 is operated ( Step S55), the air sucked through the suction port 18 of the heating / drying machine main body 2 is blown out from the blowout port 20, and the air in the bathroom is circulated. Further, the buzzer 162 (see FIG. 4) of the mist generating device 52 is activated (step S56) to notify the start of water mist spraying.

  After the operation of the buzzer 162 (for example, after 3 to 5 seconds), spraying of water mist is started. That is, the water supply electromagnetic valve 67 of the mist generating device 52 is actuated (step S57), the splash mist electromagnetic valve 70 is opened, and the water from the water supply line 64 flows through the drain line 66 and the splash mist line 68. Sprayed from the mist generating nozzle 56 into the bathroom. Therefore, the bathroom space is filled with water mist, and an environment state in which the water mist effect can be experienced is obtained.

  If the stop switch 108 of the operation remote controller 93 is turned on during the water mist operation (or the set time for performing the water mist operation elapses), the process proceeds from step S59 to step S60, and the water supply electromagnetic valve 67 is closed. Water supply is completed, and the splash mist solenoid valve 70 is closed, and the spraying of water mist is completed (step S61). Further, the louver motor 32 is deactivated (S62), the circulation fan 10 is deactivated (step S63), and the ventilation fan 34 is deactivated (S64). Thus, the water mist operation of the bathroom heating dryer is performed. Ends.

  The other operation of this bathroom heater / dryer is outlined as follows. For example, in the heating operation, the circulation fan 10 of the heat source machine 36 and the heating dryer main body 2 is operated, and hot water from the heat source machine 36 is circulated through the heating heat exchanger 8 of the heating dryer main body 2, thereby heating the dryer. Hot air blows out from the outlet 20 of the main body 2, and the bathroom is filled with warm air. Further, in the drying operation, the heat source unit 36, the circulation fan 10 and the ventilation fan 34 of the heating dryer body 2 are operated, and the heated air blows out from the heating dryer body 2 and air in the bathroom (for example, Humid air) is discharged to the outside and the interior of the bathroom is kept dry. In the ventilation operation, the ventilation fan 34 of the heating / drying machine main body 2 is operated, and the air in the bathroom is discharged to the outside to ventilate the bathroom. Further, in the splash mist operation (or micro mist operation), the heat source unit 36, the circulation fan 10 of the heating / drying machine main body 2, and the components (or the configuration related to the micro mist) related to the splash mist of the mist generating device 52 are operated. The hot water from the machine 36 is circulated through the heating heat exchanger 8 of the heating / drying machine main body 2 and the mist heat exchanger 54 of the mist generating device 52, and is heated by the heating heat exchanger 8 by the action of the circulation fan 10. The blown air is blown out from the blow-out port 20, and the warm water heated in the heat exchanger for mist flows through the splash water and the line 68 (or the micro mist line 72) and is sprayed into the bathroom from the splash mist generating nozzle 56. (Or, after spraying into the circulation channel 4 from the micro mist generating nozzle 58, it flows into the bathroom. ), They are satisfied by the splash mist in the bathroom due to warm air and hot water (or micro-mist).

  In this embodiment, the condition relaxation operation (second water mist preparation operation) is performed after the water mist preparation operation (first water mist preparation operation), but this condition relaxation operation may be omitted. In this case, even if the water mist preparatory operation (first water mist preparatory operation) is continuously performed for the first set time t1, the forward temperature of the heating heat exchanger 8 (the detected temperature of the warm water forward temperature detecting means 84) is the first forward. The temperature T1 is exceeded (T> T1), or the outflow side temperature of the mist heat exchanger 54 (the detected temperature of the mist hot water temperature detecting means 88) exceeds the first set mist temperature M1 (M> M1). Then, the abnormal signal generation unit 142 generates an abnormal signal.

  As mentioned above, although one Embodiment of the bathroom heating dryer according to this invention was described, this invention is not limited to this embodiment, A various correction thru | or change is possible, without deviating from the scope of the present invention. .

  For example, in the above-described embodiment, in the case of the cool air operation, whether or not the cool air preparation operation (first cool air preparation operation) is performed by comparing the detected temperature T of the heating forward temperature detection means 84 with the first set outbound temperature T1. In the condition relaxation operation (second cool air preparation operation), the detected temperature T is compared with the second set outgoing temperature T2 to determine whether or not to return to the cool air operation. You may make it add the relationship with the absolute humidity in a bathroom. In this case, the heater / dryer main body 2 is provided with bathroom absolute humidity detecting means (not shown) for detecting the absolute humidity in the bathroom, and the controller 92 includes absolute humidity determining means (not shown). The absolute humidity used as a reference for the memory means 146, that is, the first set absolute humidity Z1 (for example, set to about 0.025 kg · kg) and the second set absolute humidity Z2 (for example, set to about 0.030 kg / kg). Is registered.

  The cool wind operation in this case is performed as shown in FIG. 7, for example. Referring to FIG. 7, when cool air switch 102 of operation remote controller 93 is turned on (step S71), timer means 144 of controller 92 measures the time (step S72), and then the detection of the temperature going forward is performed. (Step S73) Furthermore, the absolute humidity of the bathroom is detected (Step S74). This temperature detection is performed by the hot water going-out temperature detecting means 84, and this absolute humidity is made by the bathroom absolute humidity detecting means (not shown), and detection signals from the hot water going-out temperature detecting means 84 and the bathroom absolute humidity detecting means are received. It is sent to the controller 92.

  The forward temperature determining means 130 determines whether or not the detected temperature T is equal to or lower than a first set outgoing temperature T1 (for example, 50 ° C.), and the absolute humidity determining means (not shown) is the detected humidity Z. Is less than or equal to the first set absolute humidity Z1. For example, immediately after the heating operation (or drying operation, splash mist operation, micro mist operation), as described above, there is a possibility that the hot air heat-exchanged in the heating heat exchanger 8 is blown out from the outlet. Immediately after the splash mist operation (or micro mist operation), the absolute humidity in the bathroom is high, and even if the circulation fan 10 is operated and the air in the bathroom is circulated in such a humidity state, a feeling of cool breeze cannot be obtained. There is a fear.

  For this reason, the detected temperature T of the warm water going temperature detecting means 84 exceeds the first set going temperature T1 (T> T1), or the detected humidity Z of the bathroom absolute humidity detecting means (not shown) is If the first set absolute humidity Z1 is exceeded (Z> Z1), the cool wind feeling may not be obtained even if the cool wind operation is performed, and the process proceeds from step S75 to step S76, and the cool wind preparation operation (first cool wind preparation operation). ) Is performed. On the other hand, when the detected temperature T is equal to or lower than the first set outgoing temperature T1 (T ≦ T1) and the detected humidity Z of the bathroom absolute humidity detecting means is equal to or lower than the first set absolute humidity Z1 (Z ≦ Z1), heating drying is performed. Since there is no fear that hot air will blow out from the machine body 2 and there is little humidity in the bathroom and a cool wind feeling is obtained, the process proceeds from step S75 to step S77, and the cool air operation of the bathroom heater / dryer is started.

  The cool breeze preparatory operation (first cool breeze preparatory operation) is performed in the same manner as described above, and even during this cool breeze preparatory operation, temperature detection is performed by the hot water going-out temperature detection means 84 (step S79), and bathroom absolute humidity detection Humidity is detected by means (not shown) (step S80). Then, when the detected temperature T is lowered to the first set outgoing temperature T1 or less (T ≦ T1) and the detected humidity Z is lowered to the first set absolute humidity Z1 or less (Z ≦ Z1), the steps from step S81 are performed. Proceeding to S82, the outgoing temperature determining means 130 determines that the outgoing temperature of the heat exchanger 8 for heating is lowered and there is no risk of hot air blowing, and the absolute humidity determining means (not shown) is used in the bathroom. It is determined that the environment is in an environment where the humidity is lowered and a cool breeze is obtained, and the ventilation fan 34 is deactivated based on these determination results. Further, the operation switching signal generating means 140 generates an operation switching signal, and the operation is switched based on this operation switching signal (step S83), the cool air preparation operation (first cool air preparation operation) is completed, and the cool air operation is completed. Is started (step S77).

  When this cool breeze preparatory operation (first cool breeze preparatory operation) is continuously performed for the first set time t1 (for example, 5 minutes), the process proceeds from step S81 to step S84 to step S85, and as described above, the bathroom heating dryer The condition relaxation operation (second cool breeze preparation operation) is performed. In this condition relaxation operation, the first set outgoing temperature T1 (for example, 50 ° C.) is switched to the second set outgoing temperature T2 (for example, 55 ° C.), and the first set absolute humidity Z1 (for example, 0.025 kg / day). kg) to the second set absolute humidity Z2 (for example, 0.030 kg / kg) to determine the temperature and the absolute humidity.

  Even during this condition relaxation operation (second cool breeze preparatory operation), temperature detection by the warm water going-out temperature detection means 84 is performed (step S86), and humidity detection by the bathroom absolute humidity detection means (not shown) is performed ( Step S87). When the detected temperature T is lowered to the second set outgoing temperature T2 or lower (T ≦ T2) and the detected humidity Z is lowered to the second set absolute humidity Z2, the process proceeds from step S88 to step S89, where the outgoing temperature is determined. The means 130 determines that the going-out temperature of the heating heat exchanger 8 has decreased to some extent, and the absolute room determining means (not shown) determines that the absolute humidity in the bathroom has decreased to some extent, and based on these determination results. Then, the ventilation fan 34 is deactivated (step S89), and the operation is switched based on the operation switching signal generated by the operation switching signal generating means 140 (step S90), and the condition relaxation operation (second cool air preparatory operation) is performed. ) Is finished, and cool air operation is started (step S77).

  When this condition relaxation operation (second cool air preparation operation) is continuously performed for the second set time t2 (for example, 5 minutes), the process proceeds from step S88 to step S91 to step S92. The temperature of the heat exchanger 8 has exceeded the second preset temperature T2, or the absolute humidity in the bathroom has exceeded the second preset absolute humidity Z2, and some abnormality has occurred in the bathroom heater / dryer. As a result, the abnormal signal generator 142 generates an abnormal signal (step S92), and the operation of the bathroom heater / dryer is stopped (step S93).

  When the cool air operation of the bathroom heater / dryer is started in step S77, steps S94 to S101 are performed, and the contents of steps S94 to 101 are substantially the same as steps S21 to S28 in the flowchart of FIG. .

  Further, for example, in the above-described embodiment, in the case of the water mist operation, the detected temperature T of the heating forward temperature detecting means 84 is compared with the first set outgoing temperature T1, and the detected temperature M of the mist hot water temperature detecting means 88 is compared. The first set mist temperature M1 is compared to determine whether or not to perform the water mist preparation operation (first cool breeze preparation operation). As in the case of the cool air operation, this determination is performed in the bathroom. You may make it add the relationship with absolute humidity. In this case, the detected temperature T of the warm water going temperature detecting means 84 is not more than the first set going temperature T1 (T ≦ T1), and the detected temperature M of the mist hot water temperature detecting means 88 is not more than the first set mist temperature M1 (M ≦ ≤). M1) and when the detected humidity Z of the bathroom absolute humidity detecting means (not shown) is equal to or lower than the first set absolute humidity Z1 (Z ≦ Z1), the water mist operation is performed, and at least of these three conditions When one condition is not satisfied, a water mist preparation operation (first water mist preparation operation) is performed because there is a possibility that a sufficient water mist effect may not be experienced even if the water mist operation is performed.

  Further, for example, in the above-described embodiment, in the water mist condition relaxation operation (second water mist preparation operation), the detected temperature T of the heating forward temperature detecting means 84 is compared with the second preset outgoing temperature T2, and Although the detection temperature M of the mist hot water temperature detection means 88 and the second set mist temperature M2 are compared to determine whether or not to return to the water mist operation, the condition of the cool air operation is relaxed (the second cool air preparation operation). Similarly to the determination of, a relationship with the absolute humidity in the bathroom may be added to this determination. In this case, the detected temperature T of the warm water going temperature detecting means 84 is not more than the second set going temperature T2 (T ≦ T2), and the detected temperature M of the mist hot water temperature detecting means 88 is not more than the second set mist temperature M2 (M ≦ T). M2) and when the detected humidity Z of the bathroom absolute humidity detecting means (not shown) is equal to or lower than the second set absolute humidity Z2 (Z ≦ Z2), the water mist operation is performed because the water mist effect is obtained in the bathroom. Is called.
