Embodiment Construction
[0026] In order to facilitate understanding of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.
[0027] Such as figure 1 As shown, the volute tongue for an indoor unit of an air conditioner according to the present invention includes a volute tongue body 1 , and the volute tongue body 1 is provided with a windward surface 11 and a wind guiding surface 12 . In order to improve the convection environment of the airflow at the volute tongue, the present invention sets the outer surfaces of the windward surface 11 and the wind-guiding surface 12 as planes, and connects the windward surface 11 and the wind-guiding surface 12 through the curved surface section 13, so that the windward surface 11 and the wind-guiding surface 12 are connected. There is a smooth transition between the wind-guiding surfaces 12. Since the outer surfaces of the wind-winding surface 11 and the wind-guiding surface 12 are both flat,...

The invention discloses a volute throat gap for an indoor machine of an air conditioner and the indoor machine of the air conditioner. The volute throat gap body of the indoor machine of the air conditioner is provided with a windward surface and a wind guide surface; the windward surface and the wind guide surface are connected through a transitional circular arc, the outer surfaces of the windward surface and wind guide surface are both planes, the included angle between the windward surface and the wind guide surface is 58-75 degrees, and the width of the windward surface is 13-28 millimeters. The indoor unit of the air conditioner comprises the volute throat gap. According to the invention, the windward surface and wind guide surface of the volute throat gap are arranged as planes, thewindward surface and the wind guide surface are connected through the transitional circular arc with a curved surface section, the included angle between the windward surface and the wind guide surface is increased, the width of the windward surface is reduced, the air flow at the volute throat gap is stable and uniform, and the return air flow at the windward surface is reduced, so that the airoutlet efficiency of the air outlet duct and air outlet port is improved, and the noise generated during the operation of the indoor unit of the air conditioner is effectively reduced.
Description
technical field [0001] The invention relates to the field of air conditioners, in particular to a volute tongue for an indoor unit of an air conditioner and an indoor unit of the air conditioner. Background technique [0002] When the air conditioner is working, it will generate aerodynamic noise due to the rotation of the fan. As an intuitive indicator during the use of the air conditioner, noise has been paid more and more attention. [0003] Noise includes noise value and noise quality, and the ideal state is to optimize both. The aerodynamic noise of the fan includes eddy current noise and rotating noise. The eddy current noise belongs to the noise of wide frequency band and low amplitude, and the rotating noise belongs to the noise of narrow frequency band and high amplitude. Rotational noise is discrete. For the human ear, rotational noise is more difficult to accept than eddy current noise, and has a greater impact on comfort. Therefore, improving the rotating noise...
