Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] see Figure 1-Figure 3 , an outlet grille of an air conditioner external unit, comprising a grille 3 arranged between an outer frame body 1 and a central plate 2; the grille 3 has a ring rib 3.1, and the head 3.11 of the ring rib 3.1 has an air inlet end The air outlet end is larger than the tail part 3.12; a concave step 3.13 is provided between the head part 3.11 and the tail part 3.12 of the ring rib.

[0021] Furthermore, the vertical section of the head 3.11 of the circular rib 3.1 is wing-head-shaped, and the vertical section of the tail 3.12 is in the shape of a shuttle; the section width of the head 3.11 increases gradually; the section width of the tail 3.12 decreases.

[0022] Furthermore, the steps are arranged symmetrically on the upper and lower sides of the ring rib 3.1; the step 3.13 is located at the maximum width of the head 3.1...

Abstract

The invention discloses an air outlet grating of an air conditioner outdoor unit. The air outlet grating comprises a grating body arranged between an outer frame body and a central plate; the grating body is provided with a circular ring rib and is characterized in that a head part air inlet end of the circular ring rib is larger than a tail part air outlet end; and a sunk step is arranged between the head part and the tail part of the circular ring rib. The air outlet grating enables airflows to be more naturally gathered at the tail part, so that wake loss is reduced, the circulation performance and the flow state of the impeller outlet of a draught fan are improved, the efficiency and the noise reduction performance of the draught fan are improved, and the overall power consumption of is reduced. On the other hand, the air outlet grating can also play the role in improving the production efficiency during actual production. The grating is an injection molding part; a conventional grating rib strip is a straight body face; and an improved grating is of special-shaped structure. A die joint face can be placed at the plane of a rib strip step. As the two ends of the rib strip with the structure are not straight bodies and are provided with demoulding slope, demoulding of the injection molding part is ensured to be smooth, and the rib strip produced through injection molding can be effectively prevented from drag damage and technological problems including burr during production also can be effectively prevented.

Description

technical field [0001] The invention relates to an air conditioner external unit, in particular to an outlet grille of the air conditioner external unit. Background technique [0002] The entire fan system of the outdoor unit of the air conditioner serves the heat exchanger. In the outdoor unit of the air conditioner, the main flow-passing components are the heat exchanger, the motor and its bracket, the guide ring and the grille. Excluding the heat exchanger, the grid has the greatest flow loss. 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 external air conditioners have different forms, but they are all of dense mesh structure, mainly for safety considerations. From the perspective of flow performance, the dense mesh outlet grille is insta...
