Problems solved by technology

[0003] The existing air duct machine (or underground machine) series air conditioner internal units mostly adopt the way of placing the heat exchanger perpendicular to the fan outlet direction, so that the condensed water produced by the air conditioner refrigeration will affect the heat exchange effect of the air conditioner, and at the same time due to the existence of The dead angle part of the wind leads to greater air turbulence, resulting in greater fin vibration sound, and at the same time, it is easy to cause water droplets to blow out under high wind speed

Embodiment Construction

[0016] The present invention will be further described below in conjunction with the accompanying drawings.

[0017] see figure 1 , an embodiment of an indoor unit of an air duct unit in the present invention, an indoor unit of an air duct unit, comprising a casing 1, an air inlet 6 or 7 on the casing 1, an air outlet 5, and a heat exchanger 4 in the casing 1 , Centrifugal fan 8 and fan volute 2. The heat exchanger 4 is a finned tube heat exchanger, and the finned tube heat exchanger 4 has at least 2 rows (3 rows in this embodiment).

[0018] The centrifugal fan 2 and the fan volute 8 are arranged at one end of the casing 1 , and the air outlet 5 is arranged at the other end surface of the casing 1 . The air outlet 3 of the fan volute 2 is located at the upper part, and the air outlet 3 faces the air outlet 5 of the casing 1 . The heat exchanger 4 is arranged between the centrifugal fan 8 and the air outlet 5, and the upper end of the heat exchanger 4 is arranged inclined b...

Abstract

The invention provides an air pipe machine indoor machine which comprises an enclosure, an air inlet, an air outlet, a heat exchanger in the enclosure, a centrifugal fan and a fan volute, wherein the air inlet and the air outlet are positioned on the enclosure; and the centrifugal fan and the fan volute are arranged on one inner end of the enclosure, the air outlet is arranged on the other end face of the enclosure, and the heat exchanger is arranged between the centrifugal fan and the air outlet. The air pipe machine indoor machine is characterized in that the upper end of the heat exchanger is backward arranged in an inclining manner, the upper part of the heat exchanger approaches to an exhaust outlet on the upper part of the fan volute, and the included angle of the heat exchanger and the bottom surface of the enclosure is 45 degrees-75 degrees. The air pipe machine indoor machine provided by the invention has the advantages of improving the outlet air exchange efficiency of the heat exchanger and the fan, reducing the influence of the condensing water on an air conditioner, and eliminating noises generated by the heat exchanger vibration due to the outlet air of the fan.

Description

technical field [0001] The invention belongs to the technical field of air conditioner manufacturing, and mainly relates to air duct machines (or sky buried machines) [0002] The invention discloses an improvement of a series air conditioner indoor unit, specifically an air duct unit indoor unit. Background technique [0003] The existing air duct machine (or underground machine) series air conditioner internal units mostly adopt the way of placing the heat exchanger perpendicular to the fan outlet direction, so that the condensed water produced by the air conditioner refrigeration will affect the heat exchange effect of the air conditioner, and at the same time due to the existence of The dead angle part of the wind leads to greater air turbulence, resulting in a greater vibration of the fins, and at the same time, it is easy to cause the problem of water droplets blowing out under high wind speed. In recent years, the energy efficiency and noise of air-conditioning produ...
