Publication number: 20240117984Abstract: Provided is an air conditioner including an indoor unit provided with a microphone element for receiving voice instructions, such that a voice instruction spoken by an operator is acquired with high quality and control based on the voice instruction spoken by the operator is likely to be ensured. The air conditioner includes an indoor unit, a transmission unit, and a reception unit. The indoor unit has a main body and a microphone element. The main body has formed therein a blow-out port through which air-conditioned air is blown out toward a space to be air-conditioned. The microphone element accepts a voice instruction captured from a voice capturing portion arranged at a position that deviates from a ventilation space through which the air blown out from the blow-out port flows, in such a manner as to face the space to be air-conditioned. The transmission unit transmits the voice instruction accepted by the microphone element to an outside as a signal.Type: ApplicationFiled: December 15, 2023Publication date: April 11, 2024Inventors: Kousuke TSUBOI, Takao SONODA, Makoto IKEDA, Tetsushi TSUDA, Yu OTA, Yuuichi KITA, Kenji AMANO, Atsushi MATSUBARA, Tomomi KUKITA, Naoko KURIYAMA, Tomoyoshi ASHIKAGA, Gen KUMAMOTO
