Vertical air conditioner indoor unit

Abstract

PROBLEM TO BE SOLVED: To provide an inexpensive floor type air conditioner capable of blowing sufficiently conditioned air from an upper air outlet and a lower air outlet.SOLUTION: An upper passage R2 continuously extends from an upper outlet 22a of an indoor fan 22 to an upper part flow path selection mechanism 28, and a lower passage R3 continuously extends from a lower outlet 22b of the indoor fan 22 to a lower part flow path selection mechanism 29. A bypass passage R1 is connected to the upper part flow path selection mechanism 28 and the lower part flow path selection mechanism 29. The upper part flow path selection mechanism 28 is constructed to select the state that conditioned air passes through the upper passage R2 to an upper air outlet 58 or the state that the conditioned air passes from the upper passage R2 through the bypass passage R1 to a lower air outlet 59. The lower part flow path selection mechanism 29 is constructed to select the state that conditioned air passes from the lower passage R3 to the lower air outlet 59 or the state that the conditioned air passes from the lower passage R3 through the bypass passage R1 to the upper air outlet 58.

Description

technical field [0001] The present invention relates to a vertical air conditioner indoor unit, in particular to a vertical air conditioner indoor unit with exhaust ports on the upper and lower parts of the casing. Background technique [0002] Conventionally, there is known an air conditioner that has an upper exhaust port and a lower exhaust port, sucks in air from the center, tempers the sucked air with a heat exchanger, and blows the air out from the upper exhaust port and the lower exhaust port. . [0003] For example, in the conventional air conditioner shown in Patent Document 1 (Japanese Unexamined Patent Application Publication No. 2009-257709), only sufficiently conditioned air can be blown out from either the upper exhaust port or the lower exhaust port using a single heat exchanger. Air. [0004] Therefore, Patent Document 1 proposes an air conditioner in which sufficiently conditioned air is blown out from both the upper exhaust port and the lower exhaust port...

AI Technical Summary

Problems solved by technology

[0008] However, if the air conditioner of Patent Document 1 is to be configured so that air can be blown from the upper exhaust port and the lower exhaust port using two heat exchangers, the air conditioner will become an expensive device.
