Embodiment Construction

[0019] Such as figure 1 - Figure 5 As shown, the outlet grille for the air conditioner outdoor unit of the present invention includes an outer frame body 1, a center plate 2 and at least one circle of annular diffuser grilles located between the outer frame body 1 and the center plate 2. Each of the annular diffuser grids includes a number of radially arranged rear guide vanes 3, two or more adjacent rear guide vanes 3 are formed as a group, and are arranged staggeredly in the axial position. Multiple groups of rear guide vanes 3 The array forms an annular diffuser grid. The outer frame can be a square frame or a circular frame. The preferred solution of the present invention is that there are at least three circles of annular diffuser grilles between the outer frame body 1 and the central plate 2, and a connecting ring 4 between two adjacent annular diffuser grilles. It can also be said that the rear guide vane 3 of the above-mentioned annular diffuser grid connects two a...

Abstract

The invention discloses an exhaust grid for an outdoor unit of an air conditioner. The exhaust grid comprises an outer frame body, a center plate, and at least one lap of annular diffusion grids positioned between the outer frame body and the center plate. The exhaust grid is characterized in that each annular diffusion grid comprises multiple back guide blades radially arranged; two or more adjacent back guide blades form one set, and are arranged in axial positions in a staggered manner; and multiple sets of back guide blade arrays form one lap of annular diffusion grids. When the exhaust grid is applied to the outdoor unit, the flowing loss of air currents due to flowing through the grids is reduced; and the structure fully uses the flowing characteristics of the back guide blades to improve the fan efficiency in the outdoor unit. The staggered annular diffusion grid structure can relieve the impact loss of the wake jet of impeller blades to the exhaust grid to a certain extent; the exhaust air currents of the outdoor unit of the air conditioner are uniform and centralized; the air volume is high; the flowing speed is high; the stamina is high; and the air blowing distance is farther.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to an outlet grille for an outdoor unit of an air conditioner. Background technique [0002] The whole fan system of the existing air conditioner outdoor unit mainly consists of an axial flow fan, a condenser, a casing, a motor, a motor support, an air guide ring and an outlet grille. The fan system serves the heat exchanger. In the outdoor unit of the air conditioner, the main flow-passing components include the heat exchanger, the motor and its bracket, the guide ring and the outlet grille. Except for the heat exchanger, the largest flow loss is the outlet grille. If the flow loss of other fixed parts inside the fan system can be reduced, it is expected to improve the overall energy efficiency of the air conditioner, make the air volume of the fan larger, the flow rate higher, and reduce energy loss. [0003] Existing air outlet grills for outdoor units of air conditioners have ...
