Embodiment Construction

[0032] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments of the present invention and corresponding drawings. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] According to an embodiment of the present invention, a guide ring is provided, such as figure 1 Shown is a cross-sectional view of the guide ring of the present invention. Wherein, 1 is a guide ring, 11 is a first guide arc surface, and 12 is a second guide arc surface. The guide ring 1 includes an air inlet part and an air outlet part, the air inlet part...

Abstract

The invention discloses a flow guide ring, a centrifugal fan and an air conditioner. The flow guide ring comprises an air inlet portion and an air outlet portion which are connected, the air inlet portion comprises a first flow guide arc face, and the air outlet portion comprises a second flow guide arc face. According to the scheme, the defect that air intake and air exhaust of a centrifugal volute of the centrifugal fan are not uniform in the prior art can be overcome. Since the flow guide ring comprises the first flow guide arc face of the air inlet portion and further comprises the secondflow guide arc face of the air outlet portion, due to the existing of the second flow guide arc face, the second flow guide arc face can form a convex face at the outer edge of the inlet of the flow guide ring and the outlet of the flow guide ring, accordingly wall face attaching flow of the flow guide ring on the outer edge of the inlet and the outlet is enhanced, and air intake and air exhaust of the centrifugal volute of the centrifugal fan can be uniform.

Description

technical field [0001] The invention belongs to the technical field of air conditioning, and in particular relates to a guide ring, a centrifugal fan and an air conditioner. Background technique [0002] At present, the deflector ring used for the existing cabinet unit in conjunction with the centrifugal fan blades has a profile on the axial air inlet surface in the form of a single arc, or in the form of a single arc plus a straight line. [0003] The existing single-arc guide ring is fixed on the volute body of the machine inside the cabinet. The existing single-arc working surface of the diversion ring can achieve a single-direction radial rotation axial wind guiding effect only at the inlet position of the diversion ring; Neither the upper nor the outlet can play the role of changing the wind field, and it is easy to generate eddy current flow at the position of the front disk of the impeller. The fan produces a low frequency surge noise. Contents of the invention ...
