A second means of the present invention comprises an electric motor for rotationally driving a blower fan, a receiver for receiving an operation stop signal transmitted from an air conditioner, and an illuminance sensor for detecting environmental illuminance. When the receiving unit receives the operation stop signal of the air conditioner and the illuminance sensor detects a predetermined illuminance of environmental illuminance or less, the electric motor is driven. It is characterized in that a control circuit for stopping the operation is provided.

Further, the control circuit drives the electric motor when the receiving section receives the operation stop signal and the illuminance sensor detects a predetermined illuminance equal to or less than the ambient illuminance.
It is characterized in that a control circuit is provided for stopping the operation of the electric motor when a predetermined illuminance or more continues for a predetermined time.

[0008]

According to the first means of the present invention, the control circuit rotationally drives the blower fan to blow air when the operation stop signal of the air conditioner is received and when the illuminance is below a predetermined level.

According to the second means of the present invention, the control circuit rotationally drives the blower fan to blow air when the operation stop signal of the air conditioner is received and when the illuminance is below a predetermined level. Then, when the illuminance exceeds a predetermined value, that is, in the morning, the operation is stopped. At this time, the operation of the electric motor is stopped when the illuminance above a predetermined level continues for a predetermined time.

That is, by operating the mode selection switch, three modes of automatic operation, good night operation, and manual operation are selected.

Next, the automatic operation routine will be described with reference to FIG. In step S16, the air blowing is started with the air blowing amount according to the latest signal from the air conditioner 13 stored in the memory, and the swinging at the time when the operation is stopped last time is performed. The air volume according to the room temperature detected by the air conditioner 13 is set as shown in FIG. 9, and the air volume number is given according to the air volume. In step S16, it is determined whether or not the signal from the air conditioner 13 is input, and when the signal from the air conditioner 13 is input, the process proceeds to step S17.

In step S17, the difference T between the air volume number T2 currently in operation and the air volume number T1 calculated this time is calculated, and the air volume number T1 is set to T2 in step S18. In step S19, the air volume number obtained by adding the air volume difference T calculated in step S17 to the air volume number stored in the air volume memory is set in the air volume memory, and in step S20, the air volume number in the air volume memory is sent.

In the above, the vertical swing motor 35 and the horizontal swing motor 16 are driven to start three-dimensional swing, so that the user may perform three-dimensional swing at the time of starting a good night, or the fan may fall down during three-dimensional swing. Check for any.

In step S26, the air volume adjustment switch 7
When the air volume adjustment switch 7 is operated, it is determined whether or not the air volume adjustment switch 7 is operated, and in step S27, the air volume of the air volume number that is one more than the air volume of the air volume memory is set in the air volume memory, and in step S28 the air volume number of the air volume memory Blow in. The air flow rate is adjusted according to the user's preference in steps S26 to S28.

In step S29, the swing adjustment switch 10
When it is determined that the head shake adjustment switch 10 has been operated, the head shake is adjusted according to the user's preference in steps S29 to S36. When 1 minute has passed in step S37, the blowing and swinging are stopped in step S38, and the blowing amount set in steps S26 to S28 and the swinging state set in steps S29 to S36 are stored.

In step S39, it is judged whether or not the operation stop signal from the air conditioner 13 is received. If the operation stop signal of the air conditioner 13 is not received, after the sleep operation mode is selected in step S40. It is determined whether or not a predetermined time, 8 hours in the present embodiment, has elapsed. If 8 hours have elapsed, the sleep mode is canceled in step S41, and the process proceeds to the main routine. Therefore, it is possible to eliminate the inconvenience of forgetting to cancel the sleep mode and operating the vehicle in the absence of anyone.

When the operation stop signal of the air conditioner 13 is received in step S39, the process proceeds to step S42. In step S42, it is determined whether or not the blower fan 32 is rotating at that time. If it is not rotating, it is determined in step S43 whether the predetermined illuminance, here 10 lux or less.
10 Lux, that is, it is determined whether the air is off, and if it is off, the difference T between the air volume number T2 set in the air volume memory in steps S26 to S28 and the air volume number T1 calculated this time in step S44. Is calculated and step S4
In 5, the air volume number T1 is set to T2. Step S46
At, the air volume number is set to the air volume memory by adding the air volume number stored in the air volume memory to the air volume difference T calculated in step S44, and in step S47, the blowing is started with the air volume number in the air volume memory calculated in step S46. Along with
In step S48, the swing set in steps S29 to S36 is performed.

In step S49, it is judged whether or not a predetermined time, 2 hours in this embodiment, has elapsed since the operation stop signal of the air conditioner 13 was received. If 2 hours have elapsed, the operation is stopped in step S50. Then, shift to the main routine. If two hours have not elapsed in step S49, it is determined in step S51 whether or not the signal from the air conditioner 13 is received, and when the environmental information signal from the air conditioner 13 is received, the process proceeds to step S39. , Step S39
Through step S49, air is blown at an air volume corresponding to the room temperature detected by the air conditioner 13.

Further, in step S42, a blower fan
When 32 is driving, 1 lux above 10 lux of predetermined illuminance
It is determined in step S52 whether or not the operation has continued for more than an hour. If 10 lux or more has continued for one hour or more, it is determined that the dawn has come, and the operation is stopped in step S50. In step S52, when 10 lux or more of the predetermined illuminance does not continue for one hour or more, the blower fan 32 is driven to rotate as it is. In this case, the flow chart is such that it is judged that the light is turned on for a short time during the sleep, or that the light from the outside is temporarily entered, and such an operation is ignored.

[0039]

As described above, according to the configuration of claim 1 of the present invention, it is determined by the sensor of the air conditioner and the illuminance sensor attached to the fan that the air conditioner has stopped during sleep. Since the fan is operated after the air conditioner has stopped, the fan can be operated efficiently and it is not necessary to set the timer setting time of the fan in consideration of the operating time of the air conditioner. It has good effects.

According to the second aspect of the present invention, the electric motor is driven when the environmental illuminance is equal to or lower than the predetermined illuminance, and the driving of the electric motor is automatically stopped when the illuminance exceeds the predetermined illuminance. Does not have to bother to turn off the power when waking up from sleep, and also has the effect of not forgetting to turn off the power.

Furthermore, when the electric motor is driven at a predetermined illuminance or less, the electric motor does not stop unless the illuminance is continuously higher than the predetermined illuminance for a predetermined time or more. , Even if the light from the outside temporarily enters and the illuminance exceeds a certain level, the drive of the motor does not stop, so there is no inconvenience and it is easy to use and provides a comfortable environment for the user. can do.
