- an ultrasonic generator 106 having a piezoelectric buzzer 162 for sending ultrasonic waves toward a room is disposed facing the back of the front part 121.
- the piezoelectric buzzer 16 2 is arranged at a position closer to the front side in the air conditioner.
- air conditioners are often arranged so that the indoor living space is located ahead. For this reason, in this air conditioner, the piezoelectric buzzer 162 is located closer to the occupant in the indoor unit 102.
- the piezoelectric buzzer 16 2 is disposed in front of the heat exchanger 104, there may be obstacles to the ultrasonic wave such as the heat exchanger 104 in front of the piezoelectric buzzer 16 2. Few. Obedience In this air conditioner, ultrasonic waves can be transmitted to the occupants more sufficiently.
- the ultrasonic generator 6 a plurality of transmitting units having different characteristics may be used in combination. If the frequency band of generated ultrasonic waves is wide and a single ultrasonic wave transmitter cannot oscillate ultrasonic waves of a frequency in that range, a combination of multiple transmitters with different characteristics can be used. A wider frequency band can be covered.
- a highly versatile transmitter as the combined transmitter. For example, if you want to generate ultrasonic waves in the frequency band of 20 kHz or more and 60 kHz or less, a piezoelectric element for a buzzer corresponding to a frequency of about 20 kHz and a piezoelectric element for distance measurement corresponding to a frequency of about 40 kHz Should be combined with Such devices are highly versatile and inexpensive. For this reason, the cost of the ultrasonic generator 6 can be reduced.
- ultrasonic waves having a frequency of 20 kHz or more and 100 kHz or less are generated, but ultrasonic waves of other frequencies may be generated as necessary.
- the frequency should be between 20 kHz and 50 kHz. As described above, the upper limit of the frequency may be lowered.
- the air conditioner 1 is a device that blows conditioned air, which has been subjected to cooling and heating and humidity control, into a room and thereby conditioned the indoor air.
- the ultrasonic generator 6 may be provided in an air purifier that blows air from which odor or the like has been removed into a room. Also in this case, the generation of ultrasonic waves can improve the occupant's comfort.
- the air conditioner is not limited to the wall-mounted type, but may be a floor-standing type. Even in such a case, the ultrasonic waves can reach the occupants, and the feeling of comfort can be improved.
- a hypersonic effect can be provided.
- the sound waves can reach the occupant, and the occupant's feeling of comfort can be improved.
