Abstract

The invention discloses an indoor machine of a two-tubular air conditioner, which comprises a housing, a left and a right tubular fan wheels, a heat exchanger, an air inlet and an air outlet, wherein the housing consists of a front panel assembly and a shell; the left and the right tubular fan wheels are vertically arranged in the housing; the heat exchanger is arranged in the housing and positioned at the rear side of the tubular fan wheels; the air inlet is arranged behind the housing and the air outlet is arranged in front of the housing; the shell is connected to the rear side of the front panel assembly, the inner side of the shell is provided with a box body corresponding to the heat exchanger; back parts of the box body and the shell protrude outwards, the protruding part of the box body is provided with the air inlet, and the protruding part of the shell is provided with an air inlet window corresponding to the air inlet; the heat exchanger is bent towards the protruding direction of the back of the box body and arranged at a position close to the air inlet; and the housing is also internally provided with a volute assembly positioned between the two tubular fan wheels, the volute assembly comprises a left volute, a right volute, and a connecting bulge for connecting the left volute and the right volute together, and the connecting bulge extends to the position close to the heat exchanger. The invention has the advantages of larger air inlet area, compact assembly, low cost, small noise and high heat exchange efficiency.

Description

technical field [0001] The invention relates to a split type air conditioner, in particular to an indoor unit of a double cross-flow air conditioner. Background technique [0002] At present, the structure of the indoor unit of the split floor air conditioner is usually composed of the following brief components: a housing, a centrifugal wind wheel, and a heat exchanger. There is an air outlet, and the centrifugal wind wheel is installed at the lower part of the casing. The entire air supply and heat exchange process is driven by the centrifugal wind wheel to enter the air from the lower side (and the lower front) of the air conditioner, and the air is discharged after passing through the flat plate heat exchanger on the upper part of the air conditioner. This structural method not only has the disadvantages of long air duct, high noise, and low heat transfer efficiency of the overall heat exchanger, but more importantly, the uncompact structure of the whole machine leads t...
