Moreover, FIG. 3 is a block diagram showing the principal part structure of the other bathroom clothing drying apparatus concerning this embodiment.
FIG. 4 is a schematic conceptual diagram for explaining the clothes drying operation of the bathroom clothes drying apparatus according to the present embodiment.
Note that the block diagrams shown in FIG. 2 and FIG. 3 collectively show the airway system and the electrical system.

  As shown in FIG. 1, the bathroom clothing drying apparatus 100 according to this embodiment is installed on the ceiling 11 of the bathroom 10. The bathroom clothing drying apparatus 100 according to the present embodiment includes, for example, a “hot air drying operation” that outputs a heater and sends warm air into the bathroom 10 and ventilates a part of the air inside the bathroom 10, and the bathroom. “Ventilation operation” that ventilates the air inside the bathroom 10, “Heating operation” that heats the air inside the bathroom 10, and air is sent to the interior of the bathroom 10 without the output of the heater, and the air inside the bathroom 10 “Cool air drying operation” in which a part is ventilated can be executed.

  The bathroom clothing drying apparatus 100 according to the present embodiment includes, for example, a bathroom clothing drying apparatus 100a called “1 fan type” that ventilates only the bathroom 10, and a bathroom, a toilet, and the like adjacent to the bathroom 10 And a bathroom clothes drying apparatus 100b called “2 fan type” that performs ventilation.

  As shown in FIG. 2, the “1 fan type” bathroom clothing drying apparatus 100 a includes an internal flow path 125, a sensor 131, a fan 133, a damper 135, a heater 137, a discharge path 127, and control means. 110.

  The internal flow path 125 allows the suction port 121 that sucks in air to communicate with the blow-out port 123 that blows out air, and guides the air sucked from the suction port 121 to the blow-out port 123. The fan 133 is provided in the internal flow path 125. The fan 133 sucks air from the suction port 121 and generates a flow in the air in the internal flow path 125 sucked from the suction port 121. The damper 135 is appropriately driven to change the rate at which the air sent from the fan 133 is sent to the internal flow path 125 toward the outlet 123 and the rate at which the air is sent to the discharge path 127. The discharge path 127 branches from the internal flow path 125 in the damper 135 and discharges at least a part of the air in the internal flow path 125 sucked from the suction port 121 to the outside of the bathroom 10. The sensor 131 can detect the temperature of the air flowing through the internal flow path 125. The control unit 110 can control the operations of the fan 133, the damper 135, and the heater 137.

  On the other hand, the “2 fan type” bathroom garment drying apparatus 100 b includes two fans, whereas the “1 fan type” bathroom garment drying apparatus 100 a includes one fan 133. That is, as shown in FIG. 3, the “2 fan type” bathroom clothing drying apparatus 100 b includes a circulation fan 133 a and a ventilation fan 133 b. Circulation fan 133a is provided in internal flow path 125, and is used when performing “warm air drying operation”, “heating operation”, and “cool air drying operation”. The circulation fan 133 a sucks air from the suction port 121 and generates a flow in the air in the internal flow path 125 sucked from the suction port 121. The ventilation fan 133 b is provided in the discharge path 127 on the downstream side of the damper 135. The ventilation fan 133 b sucks air from the opening of the damper 135 and generates a flow in the air of the discharge path 127 sucked from the opening of the damper 135. The other main configuration is the same as the main configuration of the “1 fan type” bathroom clothing drying apparatus 100a described above with reference to FIG.

  Here, when performing the “warm air drying operation”, the bathroom clothes drying apparatus 100 sucks air from, for example, a louver of a door (not shown) of the bathroom 10 as indicated by an arrow A1 illustrated in FIG. Air is sucked into the internal flow path 125 from the mouth 121. Then, as indicated by an arrow A <b> 2 illustrated in FIG. 1, the bathroom clothing drying apparatus 100 uses a part of the air in the internal flow path 125 sucked from the suction port 121 as air heated by the heater 137 (hot air). 10 inside. In addition, as shown by an arrow A5 in FIG. 1, the bathroom clothing drying apparatus 100 discharges another part of the air in the internal flow path 125 sucked from the suction port 121 to the outside of the bathroom 10. Ventilate the internal air.

  The heat of the warm air sent into the bathroom 10 is used to dry the clothing 21 as shown by arrows A3 and A4 shown in FIG. 1, or the bathroom clothing as shown by arrow A5 shown in FIG. It is discharged to the outside of the bathroom 10 by the ventilation operation of the drying device 100 or discharged to the outside of the bathroom 10 by heat transfer through the wall 13 of the bathroom 10.

Here, when the present inventor continuously outputs the heater 137 in the clothes drying operation, in the second half of the output time, the heat generated in the heater 137 (bathroom 10) compared to the first half of the output time. It was found that the heat of the warm air that was introduced into the interior of the bathroom was not used to dry the clothes 21 and was easily escaped to the outside of the bathroom 10 by heat transfer through the wall 13 of the bathroom 10. In other words, in the case of the clothes drying operation in which the output of the heater 137 is continued for a relatively long time, the present inventor has a temperature difference between the wall 13 of the bathroom 10 and the outside of the bathroom 10 in the latter half of the output time of the heater 137. Since the state where the temperature difference tends to increase and the temperature difference continues increases, the inventors have found that heat transmitted to the wall 13 of the bathroom 10 can easily escape to the outside of the bathroom 10. For example, if the inventor continues to output the heater 137 in the clothes drying operation as a result of the study, for example, the heat of the hot air introduced into the bathroom 10 (see arrow A2) in the latter half of the output time. It was found that 50% or more of the heat escaped to the outside of the bathroom 10 by heat transfer through the wall 13 of the bathroom 10 (see arrow A6).
In the specification of the present application, “clothing drying operation” refers to a series of operations in which the bathroom clothing drying apparatus 100 according to the present embodiment dries the clothing 21 in the bathroom 10, and includes “warm air drying operation” and “cool air”. Operation including at least one of “dry operation” shall be said.

  In contrast, as shown in FIG. 4, the control means 110 of the bathroom clothing drying apparatus 100 according to the present embodiment sets the output time (warm air drying time) of the heater 137 to the first warm air drying time and the first warm air drying time. It is divided into two warm air drying times, and the air in the bathroom 10 is circulated without the output of the heater 137 between the first hot air drying time and the second hot air drying time (cool air drying time). Eco-drying operation can be performed.

  According to this, it is possible to reduce the heat escaping from the wall 13 of the bathroom 10 to the outside of the bathroom 10 in the latter half of the output time of the heater 137, and the flow of the cool air in the cool air drying operation in which the output of the heater 137 is not performed. By utilizing this, it is possible to reduce the overall output time of the heater 137 as compared with a clothes drying operation in which the output of the heater 137 is continuously performed without providing a cool air drying time. Therefore, it is possible to improve the drying efficiency while saving energy.

Next, a specific example of the bathroom clothing drying apparatus 100 according to the present embodiment will be described with reference to the drawings.
FIG. 5 is a schematic cross-sectional view illustrating a specific example of the bathroom clothing drying apparatus of this embodiment.
FIG. 6 is a schematic cross-sectional view showing the position of the damper during the heating operation of this example.
FIG. 7 is a schematic cross-sectional view showing the position of the damper during the hot air drying operation and the cool air drying operation of this example.
FIG. 8 is a schematic cross-sectional view showing the position of the damper during the ventilation operation of this example.

  The bathroom clothing drying apparatus 100a of this specific example is the so-called “1 fan type” bathroom clothing drying apparatus described above with reference to FIG. As shown in FIGS. 5 to 8, the bathroom clothes drying apparatus 100 a of this specific example includes a housing 101, an internal flow path 125, a sensor 131, a fan 133, a damper 135, a heater 137, and a discharge. A route 127. The internal flow path 125, the sensor 131, the fan 133, the damper 135, the heater 137, and the discharge path 127 are provided inside the housing 101. As indicated by an arrow A <b> 11 illustrated in FIG. 5, the air sucked from the suction port 121 is guided to the air outlet 123 by the internal flow path 125 and the fan 133. Other configurations and structures are as described above with reference to FIG.

  Here, when the bathroom clothes drying apparatus 100a performs the “heating operation”, as shown in FIG. 6, the damper 135 blocks the discharge path 127. Therefore, as indicated by an arrow A <b> 12 illustrated in FIG. 6, all of the air in the internal flow path 125 sucked from the suction port 121 is guided to the internal flow path 125 toward the blowout port 123. And the air which goes to the blower outlet 123 is warmed by the heater 137, and is sent in the inside of the bathroom 10 as warm air. That is, when the bathroom clothes drying apparatus 100a performs the “heating operation”, the air inside the bathroom 10 is not ventilated.

  When the bathroom clothing drying apparatus 100a performs “warm air drying operation” and “cool air drying operation”, the damper 135 opens a part of the discharge path 127 as shown in FIG. . Therefore, as indicated by an arrow A <b> 13 illustrated in FIG. 7, a part of the air in the internal flow path 125 sucked from the suction port 121 is guided to the discharge path 127 and discharged to the outside of the bathroom 10. Further, as indicated by an arrow A <b> 14 illustrated in FIG. 7, another part of the air in the internal flow path 125 sucked from the suction port 121 is guided to the internal flow path 125 toward the air outlet 123. That is, when the bathroom clothing drying apparatus 100a performs “warm air drying operation” and “cool air drying operation”, air is blown out from the air outlet 123 to the bathroom 10, and the air in the bathroom 10 is circulated and the inlet 121 is circulated. A part of the air in the internal flow path 125 sucked from the air is ventilated.

  In the case of “warm air drying operation”, the air toward the air outlet 123 is heated by the heater 137 and sent into the bathroom 10 as warm air. On the other hand, in the case of “cool air drying operation”, the control unit 110 stops the output of the heater, and the air toward the air outlet 123 is sent into the bathroom 10 as cool air without being heated by the heater 137.

  When the bathroom clothes drying apparatus 100a performs “ventilation operation”, as shown in FIG. 8, the damper 135 fully opens the discharge path 127 and closes the internal flow path 125 toward the outlet 123. Yes. Therefore, as indicated by an arrow A <b> 15 illustrated in FIG. 8, all the air in the internal flow path 125 sucked from the suction port 121 is guided to the discharge path 127 and discharged to the outside of the bathroom 10.

FIG. 9 is a schematic cross-sectional view illustrating a specific example of the bathroom clothing drying apparatus of this embodiment.
The bathroom clothes drying apparatus 100b of this specific example is the so-called “2 fan type” bathroom clothes drying apparatus described above with reference to FIG.

  As shown in FIG. 9, the bathroom clothing drying apparatus 100b of this example includes a first casing 101a, a second casing 101b, an internal flow path 125, a sensor 131, and a circulation fan 133a. And a ventilation fan 133b, a damper 135, a heater 137, and a discharge path 127. The internal flow path 125, the sensor 131, the circulation fan 133a, and the heater 137 are provided inside the first casing 101a. The ventilation fan 133b and the discharge path 127 are provided inside the second casing 101b. The damper 135 is provided at a connection portion between the first casing 101a and the second casing 101b.

  The first casing 101a and the second casing 101b communicate with each other through a connection port (not shown). Therefore, for example, when the damper 135 is open like the damper 135b and the damper 135c illustrated in FIG. 9, at least a part of the air in the internal flow path 125 sucked from the suction port 121 is discharged to the discharge path 127. Can flow to. Other configurations and structures are as described above with reference to FIG.

  Here, when the bathroom clothes drying apparatus 100b performs the “heating operation”, the damper 135 closes the connection port and the discharge path 127 like the damper 135a illustrated in FIG. 9. Therefore, as indicated by an arrow A21 illustrated in FIG. 9, all of the air in the internal flow path 125 sucked from the suction port 121 is guided to the internal flow path 125 toward the blowout port 123. The other air flows are the same as the air flows in the “heating operation” of the “1 fan type” bathroom clothing drying apparatus 100a described above with reference to FIG.

  In addition, when the bathroom clothing drying apparatus 100b performs “warm air drying operation” and “cool air drying operation”, the damper 135 is connected to the connection port and the discharge path 127 as in the damper 135b illustrated in FIG. The part is open. Therefore, a part of the air in the internal flow path 125 sucked from the suction port 121 is guided to the discharge path 127 and discharged to the outside of the bathroom 10 through the exhaust connection port 129 provided in the second housing 101b. The The other air flows are the same as the air flows in the “hot air drying operation” and “cool air drying operation” of the “1 fan type” bathroom clothing drying apparatus 100a described above with reference to FIG.

  Further, when the bathroom clothes drying apparatus 100b performs the “ventilation operation”, the damper 135 has the connection port and the discharge path 127 fully opened as in the damper 135c illustrated in FIG. Therefore, all of the air in the internal flow path 125 sucked from the suction port 121 is guided to the discharge path 127 and discharged to the outside of the bathroom 10 through the exhaust connection port 129.

  The second casing 101b is provided with an exhaust connection port 129 and an intake connection port 128. As described above, the air guided to the discharge path 127 is discharged to the outside of the bathroom 10 through the exhaust connection port 129. Air sucked from a bathroom or toilet adjacent to the bathroom 10 is guided to the inside of the housing 101b through the intake connection port 128, and is passed through the exhaust connection port 129 by the ventilation fan 133b and the discharge path 127. 10 is discharged to the outside.

Next, a specific example of the operation of the bathroom clothing drying apparatus 100 according to the present embodiment will be described with reference to the drawings.
FIG. 10 is a flowchart illustrating a specific example of the operation of the bathroom clothing drying apparatus according to the present embodiment.
FIG. 11 is a schematic schematic diagram illustrating a specific example of the operation of the bathroom clothing drying apparatus according to the present embodiment.
FIG. 12 is a table illustrating an example of the heater output time in the relationship between the clothes drying set time and the outside air temperature.
FIG. 11 is a schematic diagram illustrating the operation when the clothing weight is 2 kilograms (kg), the outside air temperature is 15 degrees (° C.), and the clothing drying time (set time) is 8 hours.

  First, when executing the clothes drying operation, the user estimates the weight of the clothes 21 suspended in the bathroom 10 and sets the clothes drying time using a remote controller (not shown) (step S101). As shown in FIG. 12, for example, when the user estimates that the weight of the clothing 21 is “2 kg”, the user sets the clothing drying time to “8 hours”. For example, when the user estimates that the weight of the clothing 21 is “5 kg”, the clothing drying time is set to “10 hours”. For example, when the user estimates that the weight of the clothing 21 is “7 kg”, the clothing drying time is set to “12 hours”.

  In the specific example shown in FIG. 11, the user estimates that the weight of the clothing 21 is “2 kg”, and sets the clothing drying time to “8 hours (480 minutes)” based on the table shown in FIG. Yes.

  Subsequently, when the user sets the clothes drying time, the control unit 110 starts operation, and first executes a cool air drying operation (step S103). As described above with reference to FIG. 7, the bathroom clothing drying apparatus 100 circulates the air in the bathroom 10 and ventilates a part of the air in the bathroom 10 when performing the “cool air drying operation”. Thus, the bathroom clothing drying apparatus 100 according to the present embodiment exhausts the air inside the bathroom 10 at the beginning of the clothing drying operation.

  Subsequently, as shown in FIG. 11, when a predetermined time (in this specific example, 30 minutes) elapses (step S <b> 105: Yes), the control unit 110 causes the temperature (outside temperature) of the bathroom 10 at this time, that is, the internal flow. The temperature of the air flowing through the path 125 is detected by the sensor 131 (step S107). Here, the “predetermined time” means that the air inside the bathroom 10 is sufficiently replaced after the cool air drying operation is started, and the temperature of the bathroom 10 is, for example, the temperature (outside temperature) of a bathroom or a corridor. The time until it becomes equivalent shall be said. And the control means 110 determines the output time of the heater 137 based on the temperature detected by the sensor 131 (step S109).

  Subsequently, the control unit 110 divides the output time of the heater 137 into a first hot air drying time and a second hot air drying time. Furthermore, the control means 110 provides a cool air drying time between the first hot air drying time and the second hot air drying time.

  In the specific example shown in FIG. 11, since the outside air temperature is 15 ° C., the control unit 110 determines the heater output time as “90 minutes” based on the table shown in FIG. 12. Subsequently, the controller 110 divides the heater output time “90 minutes” into a first hot air drying time “60 minutes” and a second hot air drying time “30 minutes”. Furthermore, the control means 110 provides “360 minutes” of the cool air drying time between the first hot air drying time and the second hot air drying time. The cool air drying time (360 minutes) between the first hot air drying time and the second hot air drying time is from the clothing drying time (480 minutes) to the cool air drying time (30 minutes) at the start of operation. And the first hot air drying time (60 minutes) and the second hot air drying time (30 minutes) are subtracted.

  Subsequently, the control unit 110 executes a first hot air drying operation (step S111). Subsequently, when the first hot air drying time (60 minutes in this specific example) has elapsed (step S113: Yes), the control unit 110 ends the first hot air drying operation and executes the cool air drying operation ( Step S115). This makes it possible to reduce the heat escaping from the wall 13 of the bathroom 10 to the outside of the bathroom 10 in the latter half of the output time of the heater 137, and provides a cool air drying time using the flow of cool air in the cool air drying operation. Therefore, the output time of the heater 137 can be shortened as a whole as compared with the clothes drying operation in which the output of the heater 137 is continuously performed. Therefore, it is possible to improve the drying efficiency while saving energy.

  Subsequently, when the cool air drying time (360 minutes in this specific example) has elapsed (step S117: Yes), the control unit 110 ends the cool air drying operation and executes the second hot air drying operation (step S119). Subsequently, when the second hot air drying time (30 minutes in this specific example) has elapsed (step S121: Yes), the control unit 110 ends the second hot air drying operation and ends (stops) the clothing drying operation. (Step S123).

  According to this example, the first hot air drying time is longer than the second hot air drying time. Therefore, even when the user wants to cancel the clothes drying operation and change to another operation, the drying of most of the clothes has been completed. Therefore, the user can easily change to another driving. Thereby, it is possible to meet the needs of users who rush to dry clothes.

  Further, the control means 110 of this specific example ends (completes) the clothes drying operation simultaneously with the end of the second hot air drying time. That is, the end of the second warm air drying time coincides with the time for completing the clothes drying operation. Thereby, clothing can be warmed by the second hot air drying operation, and the clothing can be finished in a plump state.

  Further, the control means 110 of this specific example detects the temperature of the air flowing through the internal flow path 125 by the sensor 131 after the air inside the bathroom 10 is discharged at the beginning of the clothes drying operation. If the temperature inside the bathroom 10 is detected by the sensor 131 when the air inside the bathroom 10 is not exhausted sufficiently, the control means 110 may erroneously detect the temperature as being significantly different from the outside air temperature. On the other hand, in this specific example, the control means 110 can suppress erroneous detection by performing temperature detection by the sensor 131 after exhausting the air inside the bathroom 10.

  Further, as shown in FIGS. 5 and 9, the sensor 131 is located on the fan 133 (circulation fan 133 a) side in the internal flow path 125 between the suction port 121 and the fan 133 (circulation fan 133 a). Is arranged. Therefore, the sensor 131 detects the temperature of the part where the temperature of the air sucked from the suction port 121 tends to become more uniform. Thereby, the sensor 131 can detect the temperature of air more correctly, and can determine the output time of a heater more accurately.

Next, a specific example of the operation of the bathroom clothing drying apparatus 100 according to the present embodiment will be further described with reference to the drawings.
FIG. 13 is a timing chart illustrating a specific example of the operation of the bathroom clothing drying apparatus according to the present embodiment.
The bathroom clothing drying apparatus 100a of this specific example is the so-called “1 fan type” bathroom clothing drying apparatus described above with reference to FIG.

  First, when the user sets the clothes drying time, the control unit 110 starts the operation of the fan 133, and changes the position of the damper 135 from the position of “heating operation” (see FIG. 6) to “cool air drying operation / warm air drying”. The position is changed to the “operation” position (see FIG. 7) (timing t1). At this time, since the control means 110 stops the output of the heater 137, the cool air drying operation is executed (timing t1 to t2). Thereby, the air inside the bathroom 10 is discharged at the beginning of the clothes drying operation.

  Subsequently, when a predetermined time elapses, the control unit 110 outputs the heater 137 (timing t2). Thereby, the first warm air drying operation is executed (timing t2 to t3). Subsequently, when the first hot air drying time has elapsed, the control unit 110 stops the output of the heater 137 (timing t3). Thereby, the cool air drying operation is executed (timing t3 to t4). And the heat | fever which escapes from the wall 13 of the bathroom 10 in the second half of the output time of the heater 137 to the exterior of the bathroom 10 can be reduced using the flow of the cool wind of the cool air drying operation, and the drying of the clothes 21 can be continued.

  Subsequently, when the cool air drying time has elapsed, the control unit 110 outputs the heater 137 again (timing t4). Thereby, the second hot air drying operation is executed (timing t4 to t5). Subsequently, when the second hot air drying time has elapsed, the control unit 110 stops the output of the heater 137 and stops the operation of the fan 133. Further, the control unit 110 changes the position of the damper 135 from the “cool air drying operation / warm air drying operation” position to the “heating operation” position. Thereby, the clothes drying operation ends.

FIG. 14 is a timing chart illustrating another specific example of the operation of the bathroom clothing drying apparatus according to the present embodiment.
The bathroom clothes drying apparatus 100b of this specific example is the so-called “2 fan type” bathroom clothes drying apparatus described above with reference to FIG.

  First, when the user sets the clothes drying time, the control unit 110 starts to operate the circulation fan 133a and the ventilation fan 133b (timing t11). At this time, since the control means 110 has stopped the output of the heater 137, the cool air drying operation is executed (timing t11 to t12). Thereby, the air inside the bathroom 10 is discharged at the beginning of the clothes drying operation.

Subsequently, the operation at timings t12 to t14 is the same as the operation at timings t2 to t4 of the specific example described above with reference to FIG.
Subsequently, when the second hot air drying time elapses, the control unit 110 stops the output of the heater 137 and stops the operation of the circulation fan 133a and the ventilation fan 133b (timing t15). Thereby, the clothes drying operation ends.

FIG. 15 is a timing chart illustrating still another specific example of the operation of the bathroom clothing drying apparatus according to the present embodiment.
The bathroom clothing drying apparatus 100a of this specific example is the so-called “1 fan type” bathroom clothing drying apparatus described above with reference to FIG.

As a result, while the heat is accumulated in the wall 13 of the bathroom 10, the amount of heat accumulated in the wall 13 of the bathroom 10 is discharged to the outside of the bathroom 10 by maintaining the exhaust amount to a smaller amount. Can be kept to a small amount.

  Subsequently, when a predetermined time elapses, the control unit 110 increases the number of rotations of the fan 133, and the amount of air discharged from the discharge path 127 to the outside of the bathroom 10 is reduced to the amount of exhaust during the first hot air drying time. (Timing t24). In other words, the amount of air discharged in the cool air drying operation has a portion larger than the amount of air discharged in the first hot air drying operation. According to this, since the amount of heat transferred is less after the heat accumulated in the wall 13 of the bathroom 10 is reduced, the clothes are dried by increasing the number of revolutions of the fan 133 and increasing the amount of air discharged. Can be promoted.

  Subsequently, when the cool air drying time elapses, the control unit 110 outputs the heater 137 again, and makes the rotational speed of the fan 133 equal to the rotational speed of the fan 133 in the first hot air drying operation (timing t25). . Thereby, the second hot air drying operation is executed (timing t25 to t26). Subsequently, the operation at the timing t26 is the same as the operation at the timing t5 in the specific example described above with reference to FIG.

As a result, the same effect as described above with reference to FIG. 15 is obtained.

  Subsequently, when a predetermined time elapses, the control unit 110 increases the rotational speed of the ventilation fan 133b, and reduces the amount of air discharged from the discharge path 127 to the outside of the bathroom 10 during the first hot air drying time. The exhaust amount is increased (timing t34). In other words, the amount of air discharged in the cool air drying operation has a portion larger than the amount of air discharged in the first hot air drying operation. According to this, the same effect as described above with reference to FIG. 15 can be obtained.

  Subsequently, when the cool air drying time elapses, the control unit 110 outputs the heater 137 again, and makes the rotational speed of the ventilation fan 133b equal to the rotational speed of the ventilation fan 133b in the first hot air drying operation. (Timing t35). Thereby, the second hot air drying operation is executed (timing t35 to t36). Subsequently, the operation at the timing t36 is the same as the operation at the timing t15 of the specific example described above with reference to FIG.

  As shown in FIG. 17, the controller 200 of the bathroom clothing drying apparatus 100 according to the present embodiment includes a heating button 210 that operates “heating operation”, a drying button 220 that operates “warm air drying operation”, and “ventilation”.

Next, after pressing the + button 290 or the − button 300 to determine the start time of “heating operation”, the heating button 210 that is “heating operation” to be reserved is pressed to set “heating operation”. Thereafter, since the operation time is displayed on the display unit 270, the operation time of “heating operation” is determined by pressing the + button 290 or the − button 300, and then the reservation operation of “heating operation” is confirmed by pressing the reservation button 280. . In addition, in “ventilation operation”, “cool air drying operation”, and “drying operation” other than “heating operation”, the reserved operation of the operation can be set by the same method.

  In order to reserve “dry operation”, the user first presses the reservation button 280 once to display the start time of “dry operation” on the display unit 270. Next, after pressing the + button 290 or the − button 300 to determine the start time of “drying operation”, the “drying operation” is set by pressing the drying button 220 which is the “drying operation” to be reserved.

When the rotational speed of the fan 133 detected by the control means 110 and the rotational speed detection means is within a predetermined range with respect to the reference value, the control state of the rotational speed of the fan 133 is in a stable state. The display unit 270 includes an AM lamp 310 and a PM lamp 320 that are lit and informed to the user. In the bathroom clothes drying apparatus 100 according to the present embodiment, the AM lamp 310 and the PM lamp 320 of the display unit 270 are described as notification means. Instead of them, for example, audio means provided in the bathroom clothes drying apparatus 100 or the like is used. The user may be notified.

  As shown in FIGS. 18 to 20, in the “ventilation operation”, when the user presses the ventilation button 230 for a predetermined time, the bathroom clothing drying apparatus 100 sets the fan 133 set in the display unit 270 of the controller 200. The ventilation air volume (for example, the set value of the ventilation air volume set by the user) corresponding to the rotational speed is lit up and displayed. Further, when the rotational speed of the fan 133 is within the first range (N6 ≦ N ≦ N3), the AM lamp 310 and the PM lamp 320 of the display unit 270 are turned on, and the rotational speed of the fan 133 is in a stable state. Since the notification is made, the user can easily and accurately measure the ventilation air volume when checking the ventilation air volume. In the bathroom clothes drying apparatus 100 according to the present embodiment, the long press of the ventilation button 230 is described as the “back operation instruction” for a predetermined time, but it includes operations other than the normal operation for the controller.

  When the rotational speed of the fan 133 is within the second range (N5 ≦ N <N6, N3 <N ≦ N2), either the AM lamp 310 or the PM lamp 320 of the display unit 270 is turned on to determine the rotational speed of the fan 133.

Since the lamp 320 is provided together with the ventilation button 230 of the controller 200, the user can easily grasp that the rotation speed of the fan 133 is in a stable state. Further, since the user can determine the timing of measuring the ventilation air volume while visually checking the display unit 270 of the controller 200, the user can more easily measure the ventilation air volume.

Can be made.

  The control means 110 includes a CPU that performs arithmetic processing and a memory that stores information. The controller 200 transmits an operation signal to the control means 110 by the operation of the user.

The CPU can appropriately refer to information stored in the memory, perform processing based on the information, and store new information in the memory.

  In the case of the present embodiment, power supplied to the fan motor, damper motor, and heater 137 is supplied from the power supply circuit via the control means 110. The power circuit is directly connected to a commercial power source provided in a house where the bathroom clothes drying apparatus 100 is installed, and power is supplied from the commercial power source. The bathroom clothing drying apparatus 100 according to this embodiment automatically determines by the control means 110 as an initial check whether it is connected to a commercial power supply (for example, 100 V) having a voltage different from the corresponding power supply voltage (for example, 200 V). It has a function to do. The determination flow will be described with reference to FIG.

  In step S01, when the commercial power source and the power circuit are connected and the main power switch (not shown) of the bathroom clothing drying apparatus 100 is turned on, it is determined that the commercial power source is supplying power. However, it is also preferable that when the commercial power supply and the power supply circuit are connected and the electric power supplied from the commercial power supply is transferred to the control means 110, it is determined that the electric power is supplied from the commercial power supply. It is. According to such a determination method, even if the installer forgets to turn on the main power switch (not shown), the initial check can be executed.

If the first rotation speed (for example, 1000 ppm) is larger than the maximum rotation speed (for example, 800 ppm which is the upper limit value of variation) corresponding to the second power source, the control unit 110 can easily determine whether the voltage is the second voltage. .

  FIG. 23B shows that the first rotational speed (for example, 1000 ppm) is smaller than the minimum rotational speed (at the time of high instruction voltage) of the fan motor when the power supply voltage is the first voltage. If the first rotation speed (for example, 1000 ppm) is smaller than the minimum rotation speed (for example, 1100 ppm which is the lower limit value of variation) corresponding to the first power supply, it becomes easy for the control unit 110 to determine that it is not the first voltage. .

When the rotation speed of the fan motor continues for 2 seconds or more corresponding to the rotation speed corresponding to the first voltage (for example, the first threshold value 900 ppm or more), it is determined that the voltage supplied from the commercial power supply is the first voltage ( Step S504). On the other hand, the rotation speed of the fan motor does not continue over the rotation speed corresponding to the first voltage (for example, the first threshold value 900 ppm or more) for 2 seconds or more, and the rotation speed corresponding to the first voltage or more (for example, the second threshold value 800 ppm). When the above is not reached (step S505), it is determined that the voltage supplied from the commercial power supply is the second voltage (step S506).

  With the revision of the Building Standards Act of 2003, it is obliged to install mechanical ventilation equipment that can ventilate rooms more than 0.5 times / h as a countermeasure against sick house. Therefore, the bathroom clothing drying apparatus 100 ensures that the air in the room is exhausted to the outside by making the air volume for exhausting the air in the room constant. In order to control the air volume for exhausting the room air to the outside, it is necessary to detect the exhaust pressure loss of the exhaust duct connected to the exhaust path 127. If the exhaust pressure loss is known, the control means 110 detects the exhaust pressure loss. What is necessary is just to set the rotation speed of a fan motor so that it may become predetermined | prescribed air volume by pressure loss.

  FIG. 29 shows a control block diagram of the fan motor. The fan motor is a DC brushless high-pressure fan motor, and the control means 110 applies DC281V obtained by rectifying and smoothing commercial power supply AC200V to the fan motor. The motor drive IC of the fan motor energizes the fan motor with a duty corresponding to the magnitude of the CPU command voltage. Further, a rotation speed pulse signal corresponding to the rotation speed of the fan motor is output to the CPU from the Hall IC provided on the rotation shaft of the fan motor. In the constant air volume control in which the air volume for exhausting the room air to the outside is constant, the rotational speed (N) of the fan motor can be detected by a rotational speed pulse signal from the fan motor. On the other hand, for the fan motor work (W), the fan motor work (W) is estimated from “fan motor power (W)”. If the rotation speed (N) and the fan motor work (W) are known, the bathroom clothing drying apparatus 100 determines the exhaust pressure loss from the relationship between the torque (T) and the rotation speed (N) with respect to the fan motor work (W). It is possible to cope with changes in pressure loss due to external disturbances such as the external wind pressure of the exhaust duct and clogged dust.

  FIG. 30 shows a flowchart of the operation of constant air volume control of the bathroom clothing drying apparatus 100. When the ventilation operation is started during normal operation (step S602), the control unit 110 first drives the fan motor so that the rotation speed of the fan motor is constant at the target rotation speed N0 with n = 0 (steps S603 and S604). . The controller 110 continues to drive the fan motor at the target rotational speed N0 continuously for a predetermined time in order to stabilize the rotational speed when the fan motor is started (step S605). Thereafter, after a predetermined time has passed, the control unit 110 calculates “fan motor power (W)” from the detected applied voltage and energization current of the fan motor, and averages them to calculate the average power (W) of the fan motor. Is obtained (step S606). Next, Wn + 1 and Wn-1 are extracted from the control table stored in advance in the memory and compared with the average power (W) of the fan motor (step S607). If W <Wn−1, the value of n is incremented by 1 (step S608), and if W> Wn + 1, the value of n is decremented by 1 (step S609), and the change of the new rotational speed is repeated from the control table. If neither W <Wn + 1 nor W> Wn−1, the value of n is kept as it is and the operation at the rotational speed Nn is continued. If it will be in this state, it will drive | operate by predetermined air volume fixed control.

  FIG. 31 is a flowchart showing a specific example of the abnormality notification of the notification unit (for example, the display unit 270 and audio means) of the bathroom clothes drying apparatus 100 according to the present embodiment. When energization of the bathroom clothing drying apparatus 100 is started (S700), the ventilation fan motor is operated to start detection of the duct pressure loss (S710), and when the abnormality detection means detects that the first abnormality has occurred (S710) In step S720, the ventilation fan motor is stopped (S800), an abnormality is displayed on the controller 200, and reception of the controller is prohibited (S810). In addition, when the abnormality detecting unit does not detect the occurrence of the first abnormality (S720) and the abnormality detecting unit does not detect the occurrence of the second abnormality (S730), the operation of the ventilation fan motor continues for a predetermined time (S740). ), The duct pressure loss is determined and stored in the control means 110 (S750). When the abnormality detection unit detects the occurrence of the second abnormality (S730), the second abnormality is stored in the control unit 110, but the operation of the ventilation fan motor is continued (S790).

  Thereafter, the ventilation fan motor is stopped (S760), and when the control unit 110 stores the second abnormality (S770), the controller 200 displays an abnormality and prohibits the controller from accepting (S810). When the second abnormality is not stored in the control unit 110 (S770), the bathroom clothing drying apparatus 100 determines that the duct pressure loss detection has been completed normally and shifts to a standby state ( S780). Here, as a specific example of the first abnormality, for example, an abnormality that may interfere with the environment detection operation, such as an abnormality in the rotational speed of the fan motor, or a significant trouble in the bathroom clothing drying apparatus 100, such as the operation of the safety device. It is an abnormality recognized to have occurred, and when these abnormalities occur, it is required to once cut off the energization to the bathroom clothing drying apparatus 100 in order to confirm the cause. In addition, as a specific example of the second abnormality, for example, a temporary or partial abnormality such as a communication abnormality of the controller 200, and the abnormality that causes little trouble to the bathroom clothing drying apparatus 100 even if energization is continued. Yes, in the case of communication abnormality of the controller 200, if the communication is normal, it returns to the normal state.

  In the ventilator 100 of the present invention, the duct connection state is the position of a plurality of intake air passages or exhaust air passages 127. The duct connection state is the number of a plurality of intake air passages or exhaust air passages 127. The control content is a control parameter for controlling the fan 133b. The control content is the largest maximum exhaust air volume among the exhaust air volumes. The ventilation device 100 is a bathroom dryer provided in a bathroom.

  In the ventilator 100 of the present invention, the control content is the amount of exhaust air discharged from the exhaust air passage 127. Specifically, the control means 110 sets the maximum exhaust air volume when detecting one intake air path to 150 m <3> / h and the maximum exhaust air volume when detecting two air paths is 180 m <3> / h. Thereby, excessive ventilation when there are few intake air paths can be prevented, and the noise which generate | occur | produces in an intake air path can be suppressed.
