Description

  The present invention relates to drying of a bathroom with a bathroom heating / drying apparatus, for example, drying performed after bathing such as taking a mist in the bathroom.

  In recent years, in a bathroom heating / drying machine installed on the ceiling above the bathtub in the bathroom so that the bathroom can be heated, dried, or ventilated, a mist sauna bath can be made by spraying hot water mist into the bathroom. There has been proposed a bathroom heater / dryer with a mist sauna function (see, for example, Patent Document 1 and Patent Document 2).

  If such a bathroom heater / dryer with mist sauna function is installed in the bathroom, the mist sauna bath can be performed in the bathroom, but the humidity in the bathroom is 100% and the temperature in the bathroom is 40-42 ° C. It is necessary to perform a ventilation operation as a countermeasure in the bathroom after the mist sauna operation is finished (for example, see Patent Document 3 for a ventilation operation after the mist sauna bath) or a dry operation.

However, it takes about 6 hours to ventilate the bathroom after mist sauna operation, so it takes about 1 to 2 hours to dry the bathroom in 1 to 2 hours. Operation) is recommended.

  However, if heating and drying operation is performed immediately after the mist sauna operation is finished, the temperature in the bathroom rises by blowing hot air into the bathroom, and the absolute humidity of the air in the bathroom remains high (rather, the temperature in the bathroom increases) Therefore, the absolute humidity will rise further). In this case, as shown in FIG. 12, the air in the bathroom 2 is exhausted to the outside through the bathroom heater / dryer A, the exhaust duct 47, and the vent cap 48. When passing through 2, there is a problem that the air is cooled in the exhaust duct 47 and condensed in the exhaust duct 47, and the dew condensation water drops from the outdoor vent cap 48 to the corridor or the like. In particular, in the case of an apartment house such as a condominium, the vent cap 48 is often provided in an outdoor corridor, and when condensed water drops on the corridor, there is an adverse effect that passage of the corridor is hindered.

  The present invention has been invented in view of the above-described conventional problems, and provides a bathroom heating and drying apparatus capable of preventing the harmful effects of condensed water dripping onto a corridor while being able to dry in a bathroom in a short time. It is an object to do.

In order to solve the above problems, the bathroom heating / drying apparatus according to claim 1 of the present invention sucks air in the bathroom 2 from the suction port 1 and heats the air to blow hot air into the bathroom 2 from the blowout port 3. The heating function that heats the inside of the bathroom 2, the ventilation function that sucks the air in the bathroom 2 from the suction port 1 and exhausts it to the outside, and the air in the bathroom 2 is sucked from the suction port 1 to bring some air outdoors Heating and drying function for drying the bathroom 2 by exhausting and heating the remaining air and blowing warm air from the outlet 3 into the bathroom 2 and mist spray for spraying hot water mist into the bathroom 2 from the mist nozzle 4 ; and a function, a viable bathroom heating drying device mist sauna operation for blowing warm air while spraying hot water mist from the mist nozzle 4, the manipulator 5 in performing dry bath 2 When燥switch 6 is operated, whether the temperature in the bathroom 2 is equal to or higher than the predetermined temperature with whether the finished after a certain time of the mist sauna operation is determined is determined, mist sauna operation When the temperature in the bathroom 2 is equal to or higher than the predetermined temperature after the end of the above, the air in the bathroom 2 is first sucked from the suction port 1 to exhaust some air to the outdoors and the rest After a cool air operation that blows air from the air outlet 3 into the bathroom 2 is performed for a predetermined time, a heating and drying operation that ventilates and blows warm air is performed, and after the mist sauna operation ends, a certain time has passed and the interior of the bathroom 2 When the temperature is less than or equal to a predetermined temperature, a control unit B is provided for controlling so that the heat drying operation is performed immediately without performing the cool air operation.

With the above configuration, when the bathroom 2 is dried after the mist sauna operation, the air in the bathroom 2 is cooled before the heating and drying operation in which ventilation and warm air are blown, and the air in the bathroom 2 is cooled. Since the absolute humidity of the exhaust gas is lowered and the heat drying operation is performed from this state, it is difficult for the exhaust duct 47 to condense even if the exhaust duct 47 is cooled. Moreover, since the bathroom 2 is mainly dried by the heating and drying operation in which ventilation and warm air are blown, the bathroom 2 is dried in a short time. Accordingly, it is possible to prevent the harmful effect that the dew condensation water drops on the corridor or the like while the bathroom 2 can be dried in a short time. In addition, the cool air operation after the mist sauna operation can actively lower the absolute humidity of the air in the bathroom 2 and also the bathroom 2 can be dried, further reducing the occurrence of condensation and drying the bathroom 2. Can be further promoted. Further, when a certain period of time has elapsed after the mist sauna operation is completed and the temperature in the bathroom 2 is equal to or lower than a predetermined temperature, the heating and drying operation can be performed immediately without performing the cool air operation.

  The mist sauna apparatus according to claim 2 of the present invention sucks air in the bathroom 2 from the suction port 1 and heats the air to blow warm air from the outlet 3 into the bathroom 2 to heat the bathroom 2. Heating function, ventilation function that sucks air in the bathroom 2 from the suction port 1 and exhausts it to the outside, and sucks air in the bathroom 2 from the suction port 1 and exhausts part of the air to the outdoors and the remaining air Heating and drying function for heating and drying the bathroom 2 by blowing warm air from the outlet 3 into the bathroom 2, and bathroom heating provided with a mist spraying function for spraying hot water mist from the mist nozzle 4 into the bathroom 2 This is a drying device that has an automatic bathroom drying operation setting and release function for automatically drying the bathroom 2 after the operation of spraying hot water mist from the mist nozzle 4 is completed. Sometimes, after the operation of spraying mist is finished, the device is left for a predetermined time without blowing or ventilating, and then controlled so that the heating and drying operation of blowing ventilation and hot air is performed, and the automatic bathroom drying operation is released. When performing heating and drying while the vehicle is in operation, the controller B is provided with a control unit B that performs control so that the ventilation, ventilation, or heating and drying operation is performed immediately without being left for the predetermined time.

  By configuring as described above, when the automatic bathroom drying operation is set, when the bathroom 2 is dried after the operation of spraying mist, the bathroom 2 is heated before the heating and drying operation of blowing ventilation and warm air. The inside air is cooled, the absolute humidity of the air inside the bathroom 2 is lowered, and the heat drying operation is performed from this state, so that even if it is cooled by the exhaust duct 47, it is difficult for condensation to occur in the exhaust duct 47. Moreover, since the bathroom 2 is mainly dried by the heating and drying operation in which ventilation and warm air are blown, the bathroom 2 is dried in a short time. Accordingly, it is possible to prevent the harmful effect that the dew condensation water drops on the corridor or the like while the bathroom 2 can be dried in a short time. In addition, it is possible to suppress the generation of condensation and to promote drying by simple control that only shifts the start of the heating and drying operation in terms of time. In addition, when heating drying is executed when the automatic bathroom drying operation is cancelled, it is possible to immediately perform air blowing, ventilation or heating drying operation.

  Since the present invention is configured as described, when the bathroom is dried after the operation of spraying mist, the air in the bathroom is cooled before the heating and drying operation in which ventilation and hot air are blown. Since the absolute humidity of the air is reduced and heat drying operation is performed from this state, it is difficult to condense in the exhaust duct even if it is cooled in the exhaust duct, and it is mainly used in heat drying operation that ventilates and blows hot air. The bathroom is dried in a short time, and therefore the bathroom is dried in a short time. Therefore, while the bathroom can be dried in a short time, the effect of preventing the dew condensation from dripping onto the corridor etc. can be prevented. is there.

FIG. 4 shows a control circuit of the bathroom heater / dryer A, and the controller B can be controlled as follows by operating the controller 5 and the controller 30 by remote control.

  When the operator 5 for the dressing room or the operator 30 for the bathroom is operated in the bathroom 2 by operating the heating switch 36, the heating on-off valve 17 is opened and hot water is supplied to the heat exchanger 13 for hot air. Then, the circulation fan 14a is driven while the ventilation fan 14b is stopped, the movable louver 18 is opened, and the outlet 3 is opened. As a result, the air in the bathroom 2 is sucked into the main body 9 from the suction port 1, and the hot air heated by exchanging heat with warm water in the hot air heat exchanger 13 is blown out from the air outlet 3. Circulates and the bathroom 2 is heated. At this time, the strength can be switched by changing the air flow rate of the circulation fan 14a by switching the strength of the heating switch 36. Further, by operating the wind direction switch 33, the direction of the warm air blown from the outlet 3 can be changed.

  When the ventilation switch 38 of the dressing room operating unit 5 is operated to ventilate the bathroom 2, the heating on-off valve 17 is closed and the circulation of hot water to the hot air heat exchanger 13 is stopped. The ventilation fan 14b is driven in a state where the circulation fan 14a is stopped, the movable louver 18 is opened, and the outlet 3 is closed. Thereby, the air in the bathroom 2 is sucked into the main body 9 from the suction port 1 and is exhausted to the outside through the exhaust duct 47, whereby the ventilation in the bathroom 2 is performed. At this time, it is possible to switch the strength by changing the ventilation amount of the ventilation fan 14b by switching the strength of the ventilation switch 38.

  When the cool air switch 37 of the operating device 5 for the dressing room or the operating device 30 for the bathroom is operated to blow the cool air into the bathroom 2, the heating on-off valve 17 is closed and the heat exchanger 13 for the hot air is moved to. Supply of hot water is stopped, the circulation fan 14a and the ventilation fan 14b are driven, the movable louver 18 is opened, and the outlet 3 is opened. Thereby, the air in the bathroom 2 is sucked into the main body 9 from the suction port 1, a part of the air is exhausted to the outside through the exhaust duct 47, and the remaining air is blown into the bathroom 2 from the outlet 3. Cool air is blown into the bathroom 2. Further, by operating the wind direction switch 33, the direction of the air blown from the air outlet 3 can be changed.

  When the mist sauna operation is performed by operating the mist sauna switch 34 of the operation device 5 for the dressing room or the operation device 30 for the bathroom, the water supply opening / closing valve 23 is opened to supply water to the mist supply pipe 20 and proportionally. The valve 25 is opened and hot water is circulated through the mist heating conduit 24. As a result, the water flowing through the mist feed pipe 20 is heated by the mist heat exchanger 26, and the hot water flows through the mist feed pipe 20. In this state, the mist opening / closing valves 21a and 21b are opened, and a mist of warm water is sprayed from the mist nozzles 4a and 4b. On the other hand, when the mist sauna operation is performed, the heating on-off valve 17 is opened, hot water is supplied to the hot air heat exchanger 13, the circulation fan 14a is driven while the ventilation fan 14b is stopped, and the movable louver 18 is moved. The air outlet 3 is opened in the open state. Thereby, the air in the bathroom 2 is sucked into the main body 9 from the suction port 1, and the hot air heated by exchanging heat with warm water in the hot air heat exchanger 13 is blown out from the air outlet 3. Air circulates and the bathroom 2 is heated. In this way, mist is sprayed from the mist nozzles 4a and 4b and heated with warm air, whereby a mist sauna bath is performed. At this time, the mist sauna switch 34 can be switched between a strong mist sauna state and a weak mist sauna state by operating the mist sauna switch 34. When switched to the strong mist sauna state, the mist is sprayed from the pair of mist nozzles 4a and 4b, and when switched to the weak mist sauna state, the mist is sprayed from one of the mist nozzle 4a or the mist nozzle 4b.

  When the mist operation is performed by operating the mist switch 41 of the bathroom operating device 30, the water supply opening / closing valve 23 is opened to supply water to the mist water supply line 20, and the proportional valve 25 is opened to cause mist heating. Hot water is circulated through the conduit 24. As a result, the water flowing through the mist feed pipe 20 is heated by the mist heat exchanger 26, and the hot water flows through the mist feed pipe 20. In this state, the mist opening / closing valves 21a and 21b are opened, and a mist of warm water is sprayed from the mist nozzles 4a and 4b. At this time, the mist switch 41 can be operated to switch between a strong mist state and a weak mist state. When switched to the strong mist state, mist is sprayed from both the pair of mist nozzles 4a and 4b, and when switched to the weak mist state, mist is sprayed from either the mist nozzle 4a or the mist nozzle 4b.

  By the way, after taking a bath, especially after taking a mist sauna bath or a mist bath, the inside of the bathroom 2 is in a humid state, and the inside of the bathroom 2 needs to be dried. In the present invention, after bathing, when the drying switch 6 of the operation device 5 for the dressing room is operated to dry the bathroom 2, the temperature in the bathroom 2 is detected by the bathroom temperature thermistor TH3, and the temperature of the bathroom 2 is the predetermined temperature. (In the case of this example, for example, 35 ° C.) If the temperature is equal to or higher than that, the air in the bathroom 2 is sucked from the suction port 1 and a part of the air is exhausted to the outside from the exhaust duct 47 and the remaining air is discharged from the outlet 3 to the bathroom 2. Cool air operation that blows into the interior for a predetermined time, or ventilation operation for sucking the air in the bathroom 2 from the suction port 1 and exhausting it outside through the exhaust duct 47, or for the predetermined time in the bathroom 2 from the suction port 1 It is controlled by the control unit B so as to perform a heating and drying operation in which ventilation and hot air are blown after a predetermined time for the blowing operation to circulate and blow air so as to suck in and blow out from the blowout port 3. If the temperature in the bathroom 2 is below a predetermined temperature, and is controlled by the control unit B, as heat drying operation is performed immediately.

  When the heating and drying operation is performed, the heating on-off valve 17 is opened, hot water is supplied to the hot air heat exchanger 13, the circulation fan 14a and the ventilation fan 14b are driven, and the movable louver 18 is opened. Then, the air outlet 3 is opened. As a result, the air in the bathroom 2 is sucked into the main body 9 from the suction port 1, and the air circulates so that the hot air heated by exchanging heat with warm water in the hot air heat exchanger 13 is blown out from the air outlet 3. On the other hand, a part of the air sucked into the main body 9 is exhausted to the outside through the exhaust duct 47.

  FIG. 7 shows a flowchart of an example for controlling the operation as described above. In this figure, when the drying switch 6 is operated, when the temperature of the bathroom 2 is equal to or higher than a predetermined temperature, the heating and drying operation is performed after the cool air operation is performed first. As shown in FIG. 8, for example, in order to dry the inside of the bathroom 2 from the state where the mist sauna or the mist operation is turned off, the switch is turned on to operate the drying switch 6 of the operating device 5 for the dressing room. Then, the cool air operation for blowing cool air is started, the temperature in the bathroom 2 is detected by the bathroom temperature thermistor TH3, and if the temperature in the bathroom 2 is a predetermined temperature, for example, 35 ° C. or more, first, the cool air operation is performed for 10 minutes, for example. Then, for example, a heat drying operation is performed for 5 minutes, and then a cool air operation is performed, for example, for 5 minutes. Thereafter, the heat drying operation is performed, and the heat drying operation is performed for the time set by the operation timer. Is stopped. When the temperature in the bathroom 2 at the start of the cool breeze operation is, for example, 35 ° C. or less, the cool breeze operation is not performed, the heat drying operation is performed as it is, and the heat drying operation is performed for the time set by the operation timer. Stopped.

In the case of this example, in addition to being able to set the bathroom dry state as described above by operating the drying switch 6 of the operation device 5, it is set to the clothes dry state in which the laundry washed in the bathroom 2 is dried. Can be switched. When set to clothes drying state by operating the drying switch 6 is also adapted to drying is performed, it is controlled as described above. However, when the drying switch 6 is in a clothes drying state, the laundry is dried in a direction such as a downward direction where the laundry is easy to dry. When the drying switch 6 is in the bathroom drying state, the wind spreads throughout the bathroom 2. It is dried by swinging the wind direction.

  When the drying switch 6 is operated and the bathroom 2 is dried by controlling by the control unit B as described above, ventilation and hot air are blown if the temperature in the bathroom 2 is, for example, 35 ° C. or more. Before the heating and drying operation, the air in the bathroom 2 is cooled by the cool air operation, and the absolute humidity of the air in the bathroom 2 is lowered. Especially after the operation of the mist sauna, the temperature decreases and the absolute humidity decreases. In this state, since a heating and drying operation in which ventilation and hot air are blown is performed, even if the exhaust duct 47 cools, condensation in the exhaust duct 47 is difficult. Moreover, since the bathroom 2 is mainly dried by the heating and drying operation in which ventilation and hot air are blown, the bathroom 2 is dried in a short time. Accordingly, it is possible to prevent the harmful effect that the dew condensation water drops on the corridor or the like while the bathroom 2 can be dried in a short time.

  In the above example, the cool air operation is performed before the heating and drying operation. Instead of this cool air operation, the ventilation operation for sucking the air in the bathroom 2 from the suction port 1 and exhausting it to the outside, or the bathroom 2 from the suction port 1 is performed. The same operation can be performed even if a blowing operation is performed in which the air inside is sucked and circulated so as to blow out from the outlet 3. However, the cool air operation can lower the absolute humidity in the bathroom 2 faster and more effectively than the ventilation operation or the air blowing operation.

  Further, in the above example, after the cool air operation is performed, the heat drying operation is performed, the cool air operation is performed again, and then the heat drying operation is performed. However, as shown in FIG. However, after performing the heat drying operation after the cool air operation as in the above example, if the cool air operation is performed again, the absolute humidity in the bathroom 2 is lowered by the cool air operation and then the heat drying operation is performed again even if the absolute humidity increases somewhat. By operating in cool air, the absolute humidity can be lowered and the occurrence of condensation can be reliably suppressed.

  In the above explanation, the explanation is mainly about the drying by operating the drying switch 6 after the mist sauna or the mist bath, but after taking a normal bathing bathing in the bathtub 7 or taking a shower in the washing place. Similarly, when the drying switch 6 is operated to dry the bathroom 2, the drying is controlled in the same manner.

  As described above, the bathroom 2 can be dried by operating the drying switch 6 after completion of the mist sauna or mist operation or after normal bathing, but automatically after the mist sauna or mist operation is completed. It may have a function of performing bathroom drying operation. This automatic bathroom drying operation can be controlled by the control unit B so that after the mist sauna or mist operation is finished, the heating and drying operation is performed after being left for a certain period of time without ventilation or ventilation. This automatic bathroom drying operation function can be set to an automatic operation state or can be canceled (off) from automatic operation. This automatic bathroom drying operation can be set or canceled by the following operation, for example. Press the drying switch 6 for 2 seconds or more during the bathroom drying operation. Then, a display as shown in FIG. “A-:-” is an automatic operation release (off) display, “A1: 00” is a display that the heating and drying operation is started after one hour, and “A2: 00” is a heating and drying operation after two hours. "A3: 00" is a display that the heating and drying operation is started after 3 hours. In this display state, the timer setting switch 32 can be switched between “A-:-”, “A1: 00”, “A2: 00”, “A3: 00” by setting the automatic operation, Can be canceled.

  When the automatic bathroom drying operation is cancelled, the bathroom 2 is not automatically dried after the mist sauna or mist operation is completed. At this time, as described above, the operation of drying the bathroom 2 by manually operating the drying switch 6 is performed.

  When automatic bathroom drying operation is set, after the operation of the mist sauna or mist is finished, the heating and drying operation is performed to ventilate and blow hot air after leaving the mist sauna or mist for the set time without ventilation or ventilation. . The absolute humidity in the bathroom 2 decreases even if left for a predetermined time without ventilation or ventilation, and no condensation occurs in the ventilation duct 47 even if the drying operation is performed.

  In the above example, not only after the mist sauna or mist operation is finished, but when the drying switch 6 is operated, if the temperature in the bathroom 2 is equal to or higher than the predetermined temperature, a cool air operation or the like is first performed to lower the temperature of the bathroom 2 before heating. The drying operation is performed. However, the operation may be controlled as follows when the drying switch 6 is operated after the mist sauna or the mist operation is finished. In this case, for example, control can be performed as shown in the flowchart of FIG.

When the drying switch 6 is turned on after the mist sauna or the mist operation is finished, the cool air operation is started, it is determined whether it is within 10 minutes after the mist sauna or the mist operation is completed, and it is determined whether the temperature of the bathroom 2 is, for example, 35 ° C. or more. The If the mist sauna or mist operation is within 10 minutes, or the temperature in the bathroom 2 is 35 ° C. or higher, for example, a cool air operation is performed for 10 minutes, followed by a heat drying operation for, for example, 5 minutes, and then a cool air for, for example, 5 minutes. After that, the heating and drying operation is performed, and the heating and drying operation is performed for the time set by the operation timer, and the operation is stopped. When the drying switch 6 is turned on, if the mist sauna or mist operation has passed for 10 minutes or more and the temperature in the bathroom 2 is 35 ° C. or less, the heating / drying operation is immediately performed and the operation timer is set. The heating and drying operation is performed for the time and the operation is stopped. By doing in this way, generation | occurrence | production of the dew condensation in the ventilation duct 47 can be suppressed, and the bathroom 2 can be dried.
