Embedded air conditioner indoor unit

Abstract

The invention provides an embedded air conditioner indoor unit which comprises an air return box, an electric control box, a volute, a water receiving disc, a heat exchanger, a volute bolt and a wind wheel. The volute bolt comprises a first board, a second board and a third board. The axis of the wind wheel serves as an original point, the plane where the first board is located is not parallel to the plane in the Y direction of the axis of the wind wheel and the height of a semicircle formed by cutting the wind wheel through the plane where the first board is located is 15% larger than the diameter of the wind wheel. The second board is a first arc board concentric with the wind wheel, a gap ranging from 5 mm to 9 mm is formed between the first arc board and the wind wheel, and one end of the first arc board is connected with the first board. One end of the third board is connected with the other end of the second board and the other end of the third board is connected with the water receiving disc. According to the embedded air conditioner indoor unit, the thickness size and the width size of a product are effectively reduced, resistance of a whole wind path channel is reduced, the leakage amount of the suction end and the blowing end is optimized, so that efficiency of a fan is improved and noise is lowered.

Description

technical field [0001] The invention relates to the field of home appliances, and more specifically, to an embedded air conditioner indoor unit. Background technique [0002] Ceiling-mounted air conditioners are usually used in commercial environments, such as office buildings, shopping malls, etc. In these environments, the room floor height is relatively sufficient, and the ceiling area is also large, so there are no special restrictions on the installation thickness and length and width of the air conditioner. Require. [0003] Compared with traditional household air conditioners (such as wall-mounted air conditioners or cabinet air conditioners), since the ceiling embedded air conditioner does not occupy wall and floor space after installation, the room has a better sense of space and is more beautiful, so , more and more favored by the household market. [0004] However, the floor height of the usual household environment is not high. If you want to install a ceiling-...

Problems solved by technology

[0004] However, the floor height of the usual household environment is not high. If you want to install a ceiling-mounted air conditioner, you can only choose a product with a very thin body thickness. However, in the existing technology, almost all ultra-thin ceiling-mounted air conditioners are in After the body is thinner, not only the width dimension is increased, but also the product fan efficiency is low, the heat exchanger is poor, and the noise is high due to the reduction of the channel size.
