Embodiment 1

[0044] An air conditioner is proposed in the embodiment of the present application, which includes an indoor unit 10, referring to Figure 3 to Figure 7 , the indoor unit 10 is an air duct machine, which includes a casing 100, a fan 200 and a heat exchanger 300, the casing 100 is provided with an air inlet 110 and an air outlet 120, and the fan 200 is located in the casing 100 and is close to the air inlet 110 The heat exchanger 300 is obliquely installed in the casing 100 and is located on one side of the fan 200, and is close to the air outlet 120. When the fan 200 is working, the indoor air is sucked into the casing 100 by the air inlet 110, and then flows through the fan 200. After heat exchange, the heater 300 is discharged into the room through the air outlet 120 .

[0045] In this embodiment, the heat exchanger 300 is specifically a one-stage heat exchanger, which includes a plurality of fins 310, and the fins 310 are formed with at least one row of multiple tube holes ...

Embodiment 2

[0059] As another implementation of the indoor unit (specifically, the air duct unit) in this application, refer to Figure 9 , the heat exchanger 300 is a two-stage structure, that is, the upper heat exchanger 330 and the lower heat exchanger 340 are connected. The structure of the fins 310 in the heater is the same as that of the first embodiment, and will not be repeated here.

Abstract

The invention provides an indoor unit and an air conditioner. A heat exchanger of the indoor unit is obliquely installed. The indoor unit comprises a plurality of fins. At least one row of pipe holesdistributed in the length direction of each fin are formed in the fin, multiple cracks are formed in the surface of the part, between every two adjacent pipe holes, of each fin, the length direction of the cracks inclines relative to the horizontal direction, the inclination angle beta is larger than or equal to 90 degrees and smaller than 180 degrees, the cracks are divided into a first group ofcracks close to a lower pipe hole and a second group of cracks close to an upper pipe hole, the first group of cracks includes multiple first cracks, the second group of cracks includes multiple second cracks, at least one first crack in the multiple first cracks is positioned in an upwind area in the air supply direction of a fan, and at least one second crack in the second cracks is positioned in a downwind area. According to the indoor unit and the air conditioner, the problem that condensate water on the surface of the heat exchanger of the indoor unit in the prior art is unsmooth in drainage is solved, and smooth drainage of condensate water is guaranteed.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to the structural improvement of an air duct type indoor unit. Background technique [0002] At present, the indoor units of commercial air conditioners mainly include two types: four-sided air outlet type and ducted unit, among which ducted unit occupies a dominant position in the domestic market. The air duct machine is a new model developed in response to the diverse needs of the market and the changes in the overall decoration space. It is suitable for installation and maintenance of small width occasions, especially for small-sized families. Now users have higher and higher requirements for reducing their noise. Because the household ceiling-buried air duct machine is installed in the bedroom, it is even more necessary to effectively control the noise level of the air duct machine, and not allow abnormal noise, so as to achieve comprehensive silence. Effect. [0003]...
