Publication number: 20140134939Abstract: A wall-mounted air conditioning indoor unit includes a casing, and an air flow direction adjustment unit with plural guide blades positioned between right and left side walls of the outlet passage of the casing. A first of the guide blades is positioned closest to a predetermined side wall of the right and left side walls. In a state in which the first guide blade is postured closer to the predetermined side wall as the first guide blade extends on a downstream side, first and second gaps are formed between first and second sections of the first guide blade and the predetermined side wall, respectively. The first section is part of an end portion of the first blade on the downstream side. The second section is outside the first section. The first gap is equal to or less than 10 mm. The second gap is greater than 10 mm.Type: ApplicationFiled: June 27, 2012Publication date: May 15, 2014Inventors: Masashi Kamada, Hironobu Teraoka, Noriyuki Okuda, Tooru Shigesawa, Kouichi Yasuo, Tatsuhiko Akai, Koutarou Kuida

Patent number: 7565814Abstract: The present invention provides an indoor unit of an air conditioner, which is capable of improving the safety regarding the opening and closing movements of a movable panel. An indoor unit of an air conditioner includes a front grill, a second panel, a driving machine, and a second panel supporting member. The front grill is provided with a first intake port at a front thereof. The second panel is provided such that it covers the first intake port, opens the first intake port by moving away from the first intake port and closes the first intake port by moving close to the first intake port. The driving machine generates a driving force to move the second panel. The second panel supporting member has a gear portion and a plate member. The gear portion transmits the driving force of the driving machine to the second panel. The plate member is provided outside the gear portion, and covers a gap between the second panel and the front grill in a state in which the second panel is open.Type: GrantFiled: September 9, 2004Date of Patent: July 28, 2009Assignee: Daikin Industries, Ltd.Inventors: Tetsuya Yamashita, Tatsuhiko Akai, Takashi Doi, Atsushi Kataoka
