The drying mode is an operation mode for drying laundry such as clothes in the bathroom or in the bathroom, and drying operation by continuously energizing the heater when the drying operation for a relatively short time is desired such as drying the laundry quickly. When the standard mode is selected, and the bathroom is used to remove moisture from the room until the next morning and to dry, or to run a drying operation to dry the laundry, limit the energization time of the heater or the heater capacity. In addition, the drying operation is performed by a combination of the drying operation by energizing the heater and the blowing operation without energizing the heater, and simultaneously detecting and controlling the energization time of the heater or the temperature of the air in the room adjacent to the bathroom to which the heater capacity is sucked. By selecting the energy saving drying operation mode, the heater is energized according to the room temperature. This is controlled and made to perform efficient drying operation by energy saving.

Further, on the left half side of the surface of the controller case 15a, a remaining time display lamp group L7 for displaying the remaining time of the operation time and a stop timer setting button B6 are provided, and the stop timer setting button B6 is provided. By setting the operation time in each mode, the remaining time display is switched by one division each time it is pressed, and the remaining time is continuously switched by pressing for more than one second.

Next, the usage method of the bathroom ventilation dryer which concerns on one Embodiment of this invention is demonstrated along the flowchart of FIG.

As shown in Figs. 3 and 4, the laundry is suspended in the bathroom R1.

Next, by pressing the drying mode operation operation button B2 of the controller 15 shown in FIG. 6, a certain drying mode such as the "standard drying" mode or the "energy saving drying" mode is selected (S1).

In addition, by setting the drying mode operating time in advance in the stop timer setting button B6, the remaining time (operation time) is displayed in the remaining time display lamp group L7.

In addition, when the drying mode is selected, as shown in FIG. 5, the blower 7 is rotated through the controller 15, the fan motor controller 7a ₁ , and the fan motor 7a, and the heater controller 8c _{1 is} rotated. The 1st heater 8a and the 2nd heater 8b generate heat | fever through it. In addition, the damper motor 9a is rotated through the damper motor controller 9a ₁ , and the damper 9 is held in a half-open state as shown in FIG. 2. In the standard drying mode, air is supplied from the side R2 to the bathroom R1 through the window louver D1, and is sucked into the main body 2 from the intake port 3, so that some air is supplied to the fan motor 7a. The exhaust port 6 is exhausted from the exhaust port 6 through the duct P through the exhaust passage 13 formed above the damper 9. On the other hand, the remaining air passes through the heater 8 through the circulation passage 14 formed below the damper 9, is heated and is ejected from the jet port 4 into the bathroom R1, and the bathroom R1 by the air. ) Dry the laundry inside and in the bathroom.

When the "energy saving drying" mode of the drying mode is selected, when the operation time is set to 5 hours as shown in Fig. 8, the heater is energized for the first 1 hour and the last 30 minutes, and the other time is the heater. (8) is set to not energize. At this time, the electricity supply time or the electricity supply amount of the heater 8 which is first energized based on the temperature of the side R2 is controlled by the temperature sensor 16.

The air of the side R2 is supplied into the bathroom R1 through the window louver D1, and the air supply temperature is detected by the temperature sensor 16 (S2).

The air supply temperature is compared with the predetermined temperature T (S3).

If it is more than the set value, the controller 15 controls to shorten the energization time of the heater 8 or to reduce the energization amount (S4).

Since the relatively high temperature air is supplied into the bathroom when the lateral side R2 is relatively high temperature, the air spouted from the spout 4 is relatively fast in the bathroom R1 even when not heated by the heater 8. The laundry dries.

When the room temperature of the bathroom side R2 is less than the set value, the controller 15 controls to lengthen the time for energizing the heater 8 or to increase the capacity of the heater 8 (S5).

The air sucked from the suction port 3 is heated by the heater 8 and blown into the bathroom R1 through the circulation passage 14 and the jet port 4. The laundry is dried by the heated hot air.

In addition, when energizing and controlling the heater in two stages according to the set temperature, two sets of T1 and T2 are provided for setting the air supply temperature for determining the energization to the heater, and the air supply temperature is the first set value in the drying operation. When more than (T1), the electricity supply to one heater may be stopped, and when more than 2nd set value T2, both may stop electricity supply to a heater.

In addition, when the humidity sensor 17 is provided, the air humidity supplied can be detected, and the energization to the heater 8 is determined according to the humidity, and the drying time is also affected by the humidity of the supplied air. Further drying time can be stabilized and power consumption can be reduced.

It is determined whether the standard drying mode has elapsed for a predetermined time (S6).

After a certain time has elapsed, the controller 15 stops the blower 7 and stops energization of the heater 8 to end the drying mode.

If it has not elapsed for a predetermined time, the process returns to S3 and the cycle is repeated below by comparing the air supply temperature with a predetermined temperature (T).

As described above, according to the "energy saving drying" mode, the energization time of the heater or heater capacity which introduces air from the side room to dry in the bathroom and increases the temperature of the air sent into the bathroom by the temperature of the introduced air. When the room temperature is high by changing the temperature, the energization time is shortened or the heater capacity is reduced, so that the bathroom ventilation dryer excellent in energy saving is realized.

In addition, since the heater is energized for a predetermined time from the start of the operation, the heater is turned off thereafter, the blower operation is performed, and the energization is performed immediately before the end of the operation. By increasing the temperature of the moisture of the back, it is easy to evaporate, and afterwards, the air is blown out to release the moisture to the outside, and the temperature of clothes is increased immediately before the drying is finished. do.

In addition, since the temperature of the dried clothes or the like is increased immediately after the end to increase the dry feeling, the energization time may be fixed at about 30 minutes, and immediately after the operation, the temperature of the ventilation air is changed to the temperature of the next room. Even if the current supply time is shortened, the same effect as that at the low temperature can be obtained, so that the efficiency can be increased.

As described above, according to the bathroom ventilation dryer of the present embodiment, a bathroom ventilation dryer excellent in energy saving can be realized without impairing drying performance.

According to the bathroom ventilation dryer which concerns on this invention, the bathroom ventilation dryer excellent in energy saving can be provided, without impairing drying performance.
