Problems solved by technology

[0003] 1. Some residential areas have specially set up the installation location for the outdoor unit, which is not only in the shape of a square frame, but also has wooden or iron grille doors on the outside in order to make the building beautiful and unified, which affects the air volume of the outdoor unit.
When the outdoor unit of the air conditioner is installed in such a small compartment, the return air and exhaust air required for heat exchange of the outdoor unit can only be circulated through the front grille. The outdoor air conditioner originally has a grille on the front side, and the wind The circulation area is very small and the wind resistance is very large, which will inevitably lead to a significant drop in the heat transfer performance of the outdoor unit of the air conditioner, and even cannot guarantee the reliable operation of the air conditioner
Moreover, due to the limitation of the installation position of the external unit, the external unit blows abnormally, such as whistle, etc., and the sound is strange, which affects the user experience.
[0004] 2. The seasonal wind or the "pass wind" caused by the building structure will affect the exhaust air of the outdoor unit, resulting in affected heat dissipation

Embodiment 1

[0037] Such as Figure 1-6 As shown, an air conditioner outdoor unit grille assembly includes an outer grille 1, a guide rail mounting frame 2, an inner grille 3 and an adjustment mechanism 5, and the outer grille 1 and the inner grille 3 pass through the guide rail mounting frame 2 The guide rail mounting frame 2 connects the outer grille 1 and the inner grille 3 and makes the two relatively rotate. The inside of the inner grille is uniformly inclined along the circumference and is provided with a wind deflector 302. The inner grille 3 Driven teeth are provided at the edge, and the adjustment mechanism includes a drive box 501, a stop disc 503, a rotating toothed disc 506 and a knob disc 507, the stop disc 503 is connected with the drive box 501, and the stop disc 503 One side of the rotating toothed plate 506 is connected with the inner grid 3 through the driven gear 511 , and one side of the rotating toothed plate 506 is connected with the knob plate 507 .

[0038] The dri...

Embodiment 2

[0047] Such as Figure 7 As shown, the adjustment mechanism 5 includes a drive box 501, a rotating toothed disc 506 and a motor 9, the drive box 501 is provided with a motor 9, the output shaft of the motor 9 is connected with a rotating toothed disc 506, and the inner The edge of the grid 3 is provided with driven teeth meshing with the rotating toothed disc 506 .

[0048] Driven by the motor 9, the rotating toothed disc 506 is driven to rotate, thereby driving the inner grille to rotate, thereby realizing the adjustment of the wind direction, and the adjustment method is more convenient and quick.

[0049] All the other structures are the same as in Embodiment 1.

Embodiment 3

[0051] Such as Figure 8 As shown, the adjustment mechanism 5 includes a rack bar 8, one end of the rack bar 8 is provided with a mating tooth 802, and the edge of the inner grid 3 is provided with a driven tooth that engages with the mating tooth 802, and the tooth The other end of the bar 8 is provided with a hand-pull block 801, and the hand-pull block 801 is arranged on the casing of the air conditioner external unit. By manually sliding the hand-pull block 801 to pull the rack bar 8, the rack bar 8 drives the inner grille 3 The wind direction can be adjusted by rotating, and the adjustment mechanism has low manufacturing cost and low maintenance cost.

[0052] All the other structures are the same as in Embodiment 1.

Abstract

The invention discloses a grating assembly for an outdoor unit of an air conditioner. The grating assembly comprises an outer grating, and further comprises an inner grating and an adjusting mechanism; and air guiding plates are uniformly arranged on the inner part of the inner grating along the circumference, the air guiding plates are obliquely arranged, and the inner grating rotates by an anglethrough the adjusting mechanism. In the case of limited air volume by a grating door and the like, the air volume is increased by adjusting the inner grating; due to the adoption of a grating structure of the outdoor unit, when foreign matter blocks the front side of the installation position of the outdoor unit, the inner grating is adjusted, and thus the air outlet form and direction can be adjusted; and in the case of abnormal noise of the outdoor unit caused by the foreign matter, the air outlet direction is adjusted by adjusting the inner grating, so that the air direction avoids the foreign matter, the abnormal noise is reduced, the air outlet angle and form are adjusted through the external conditions, the power consumption can be saved, and the working efficiency of the outdoor unit is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioner outdoor units, in particular to an air conditioner outdoor unit grille assembly and an air conditioner outdoor unit. Background technique [0002] The patent No. CN204717927U Fan assembly and air conditioner outdoor unit patent discloses a grille structure, through the optimization of the structure, the air supply volume is large and the air supply noise is low. But it can only increase the air volume in a straight line, and it cannot be used in many restricted positions. The main problems at present are: [0003] 1. Some residential areas have specially set up the installation location for the outdoor unit, which is not only in the shape of a square, but also has wooden or iron grille doors on the outside in order to make the building beautiful and unified, which affects the air volume of the outdoor unit. When the outdoor unit of the air conditioner is installed in such a small compart...
