Embodiment Construction

[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the guide ring, the air duct structure and the indoor cabinet of the air conditioner of the present invention will be further described in detail through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0038] see Figure 2 to Figure 6 , the air duct structure (not shown) of the present invention includes a body (not shown), a volute (not shown), a centrifugal fan (not shown) and a guide ring 100 . The volute is installed on the body and communicated with the body, the centrifugal fan is installed in the volute, and the guide ring 100 has the effect of strengthening the flow guide.

[0039] The guide ring 100 of the present invention is installed at the edge of the inlet of the volute, which can not on...

Abstract

The invention provides a guide ring, an air duct structure and an air-conditioner indoor cabinet. The guide ring comprises a toroidal connecting portion and a guiding portion, the longitudinal section of the guiding portion is hyperbolic-type, and the cross section of the guiding portion is toroidal; the air duct structure is provided with the guide ring; the air-conditioner indoor cabinet comprises the above air duct structure. The hyperbolic-type guide ring with a guiding function is mounted, so that aerodynamic performance of the air duct structure is improved, and noise of the air-conditioner indoor cabinet is lowered during operation.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a guide ring applied to an air duct structure in an indoor cabinet of an air conditioner, an air duct structure containing the above guide ring, and an indoor cabinet machine of an air conditioner containing the above air duct structure . Background technique [0002] Currently, if figure 1 As shown, the guide ring of the air duct system of the indoor cabinet of the air conditioner generally adopts a circular arc shape, and is generally a quarter of an arc. Most of the gas passes through the guide ring along the axial direction of the motor and enters the interior of the volute. Affected by the rotation of the centrifugal fan blades, the gas needs a large turn to flow out through the flow channel between the centrifugal fan blades, so a large amount of backflow will be generated in the area between the upper part of the centrifugal fan blades and the guide ring,...
