In this embodiment, the control circuit 17
The buzzer 21 connected to the control circuit 17 constitutes a mode setting notifying device D. The mode setting notifying device D notifies the user when a predetermined mode is set by a remote operation using the wire remote controller 9. It is supposed to.

The control circuit 17 includes a light receiving unit 5 for detecting various operation signals from the wireless remote control 9, a dirt detection sensor 6, and a display control circuit for controlling the display of various lamps and indicators on the display unit 4. 18, a fan motor 19 which is a driving source of the fan 8, a high voltage power supply unit 20 for applying a high voltage to the dust collecting element 7, a power transformer 22, and a power outlet 23 are connected.

Here, the mode setting notification device D of this embodiment
One of the features of (1) is that, as described later, the control circuit 17 outputs a buzzer when the pollen mode operation switch 14 or the cleaning mode switch 15 is pressed to set the cleaning mode or the pollen mode. 21 is that the mode name is expressed by sequentially outputting sounds with a predetermined change corresponding to each syllable of the mode name.

When the user presses the cigarette mode operation switch 13 of the wireless remote controller 9 to set the cigarette mode,
The light receiving unit 5 detects the cigarette mode setting signal from the wireless remote controller 9 and transmits the signal to the control circuit 17. The control circuit 17 which has received the cigarette mode setting signal from the wireless remote controller 9 provides a display control signal to the display control circuit 18 to indicate on the display unit 4 that the cigarette mode is being operated, and the high voltage power supply unit. 20 is turned on to apply a high voltage to the dust collecting element 7. Accordingly, the control circuit 17 drives the fan motor 19 to rapidly remove smoke particles floating in the air when smoking,
Start the rapid dust collection operation.

At this time, the control circuit 17 drives the buzzer 21 to emit a buzzer sound dedicated to the cigarette mode. Specifically, the buzzer 21 emits a sound simulating a wind noise such that the number of revolutions increases when the fan is turbo-rotated. In this way, when the cigarette mode is set, the user who hears this buzzer sounds a buzzer sound that simulates a wind noise such that the rotation speed increases as the fan rises when the fan is turbo-rotated. Imagine, rapid dust collection. As a result, the user can know that the cigarette mode has been set.

When a predetermined quick dust collection operation time elapses, the control circuit 17 turns off the display of the cigarette mode operation on the display unit 4 and thereafter shifts to the automatic operation mode, where the dirt detected by the dirt detection sensor 6 is detected. Fan motor 1 according to degree
9 is controlled. When the pollen mode operation switch 14 of the wireless remote controller 9 is pressed in order to set the pollen mode, the light receiving unit 5 detects a pollen mode setting signal from the wireless remote controller 9 and controls the signal by the control circuit 17.
Tell The control circuit 17 that has received the pollen mode setting signal from the wireless remote controller 9 provides a display control signal to the display control circuit 18 to indicate that the pollen mode operation is being performed on the display unit 4 and to use the high-voltage power supply unit. 20 is turned on to apply a high voltage to the dust collecting element 7. Along with this, the control circuit 17 drives the fan motor 19 to start the pollen mode operation in order to efficiently remove the pollen floating in the air.

At this time, the control circuit 17 drives the buzzer 21 to emit a buzzer sound dedicated to the pollen mode. Specifically, referring to FIG. 5, when the pollen mode is set,
The buzzer 21 is sounded at a frequency of 3520 Hz for 0.25 seconds, and thereafter the buzzer 21 is sounded at a frequency of 4400 Hz for 0.05 seconds and then for 0.05 seconds.
The buzzer 21 is sounded at a frequency of 4690 Hz for 0.3 seconds apart.

As described above, when the pollen mode is set, the control circuit 17 sets the buzzer 21 at regular intervals.
Since the buzzer sounds and the mode name is expressed while changing the ringing frequency and the ringing time, the user hears as if the voice were output as “KA”, “FU”, and “N”. The notification of the mode name is performed once or several times according to the mode setting.

Referring again to FIG. 4, when the cleaning mode switch 15 of the wireless remote controller 9 is pressed to set the cleaning mode, the light receiving unit 5 detects the cleaning mode setting signal from the wireless remote controller 9. Then, the signal is transmitted to the control circuit 17. The control circuit 17 that has received the cleaning mode setting signal from the wireless remote controller 9 provides a display control signal to the display control circuit 18 to display on the display unit 4 that the cleaning mode operation is being performed, The power supply unit 20 is turned on to apply a high voltage to the dust collection element 7. Along with this, the control circuit 17 drives the fan motor 19 to start the rapid dust collection operation in order to quickly remove the dust soaring into the air during cleaning.

At this time, the control circuit 17 drives the buzzer 21 to emit a buzzer sound dedicated to the cleaning mode. Specifically, referring to FIG. 6, when the cleaning mode is set, the buzzer 21 is sounded at a frequency of 3520 Hz for 0.3 seconds, and then the buzzer 21 is set to a frequency of 4400 Hz for 0.4 seconds after 0.05 seconds. And then 0.05
The buzzer 21 is sounded at a frequency of 3960 Hz for 0.2 seconds apart.

As described above, when the cleaning mode is set, the control circuit 17 outputs the buzzer 2 at regular intervals.
Since the buzzer sounds and the mode name is expressed while changing the ringing frequency and ringing time of 1, the user can
It sounds as if "O", "Yes", "Ji" were output as audio. As described above, one of the features of the mode setting notification device D of the present embodiment is that when the pollen mode or the cleaning mode is set by the remote control from the wireless remote controller 9, the control circuit 17 sets the predetermined interval. In this case, the mode name is expressed by generating a buzzer sound while changing the ringing frequency and ringing time of the buzzer 21. In other words, when the pollen mode or the cleaning mode is set by the remote control from the wireless remote controller 9, the sound generated by the buzzer 21 depends on the pitch contrast for each syllable and the contrast between the long syllable and the single syllable. Since the name is expressed, the user who hears the buzzer sound can remarkably image the mode name as if it were output as voice. As a result, the user can more reliably know which of the pollen mode and the cleaning mode has been set by the remote control from the wireless remote controller 9 at the place where the remote control is performed. Moreover, the expression of the mode name using only the pitch contrast of each syllable and the contrast between the long syllable and the single syllable can be achieved by simple control using an inexpensive buzzer. The production cost of the notification device can be made very low.

[0029] Also, in the above embodiment, when the mode is set by remote control, the sound produced by the buzzer 21, the pitch contrast for each syllable, and the mode name only by contrast the long syllables and syllable Although the example of expressing is described, the above sound may express the mode name only by the contrast of the interval for each syllable, or may express the mode name only by the contrast of the long syllable and the single syllable. Good. Even in such a case, the object of the present invention can be sufficiently achieved.

Of course, various design changes and modifications can be made within the scope of the present invention.
