Description

Technical Field

[0001] The present invention relates to the technical field of air-conditioning outdoor units, in particular to an air-conditioning outdoor unit grille component and an air-conditioning outdoor unit. Background Art

[0002] Patent number CN204717927U, a fan assembly and air conditioner outdoor unit incorporating the same, discloses a grille structure that, through structural optimization, delivers high airflow and low noise. However, it can only increase airflow in a linear direction, making it unusable in many restricted locations. The main issues currently include:

[0003] 1. Some residential communities have designated installation locations for outdoor units. These are not only square-shaped, but also feature wooden or iron grilles on the outside to create a uniform aesthetic. This reduces the airflow volume. When the outdoor unit is installed in such a small compartment, the return and exhaust air required for heat exchange can only flow through the front grille. Since the outdoor unit already has a grille on the front, the airflow area is very small and the wind resistance is very high. This will inevitably lead to a significant decrease in the heat exchange performance of the outdoor unit and may even make it impossible to ensure reliable operation. Furthermore, the restricted installation location of the outdoor unit can cause unusual noises, such as whistling, which can affect the user experience.

[0004] 2. Seasonal winds or "through drafts" caused by building structures affect the exhaust of the outdoor unit, resulting in affected heat dissipation. Summary of the Invention

[0005] The present invention addresses the above-mentioned deficiencies in the prior art and provides an air conditioner outdoor unit grille assembly. When air volume is limited by a grille door or other factors, the air volume can be increased by adjusting the inner grille. Due to the use of the present invention's outdoor unit grille structure, the air outlet pattern and direction can be adjusted by adjusting the inner grille when foreign objects obstruct the front of the outdoor unit's installation location. If foreign objects cause abnormal noise from the outdoor unit's air outlet, the air outlet direction can be adjusted by adjusting the inner grille to avoid the foreign objects and reduce the noise. Adjusting the air outlet angle and pattern based on external conditions can save electricity and improve the outdoor unit's operating efficiency.

[0006] To achieve the above object, the present invention provides the following technical solutions:

DETAILED DESCRIPTION

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] An air conditioner outdoor unit includes an air conditioner outdoor unit grille assembly, and the specific structure is as follows:

[0036] Example 1:

[0037] like Figure 1-6 As shown, a grille assembly of an air conditioner outdoor unit includes an outer grille 1, a guide rail mounting frame 2, an inner grille 3 and an adjustment mechanism 5, wherein the outer grille 1 and the inner grille 3 are connected by the guide rail mounting frame 2, and the guide rail mounting frame 2 connects the outer grille 1 and the inner grille 3 and enables the two to rotate relative to each other, and the interior of the inner grille is uniformly inclined along the circumference and provided with an air guide plate 302, and the edge of the inner grille 3 is provided with a driven tooth, and the adjustment mechanism includes a drive box 501, a stopping disk 503, a rotating toothed disk 506 and a knob disk 507, the stopping disk 503 is connected to the drive box 501, and one side of the stopping disk 503 is connected to the rotating toothed disk 506, the rotating toothed disk 506 is meshed with the inner grille 3 through a driven gear 511, and one side of the rotating toothed disk 506 is connected to the knob disk 507.

[0038] A fixed shaft 514 is provided in the drive box 501, and a return spring 502 is sleeved on the fixed shaft 514. A connecting sleeve 504 that cooperates with the fixed shaft 514 is provided on one side of the stop disk 503. One end of the return spring 502 is connected to the inner wall of the drive box 501, and the other end of the return spring 502 is connected to the connecting sleeve 504.

[0039] A driven locking tooth 513 is provided on one side of the stop disc 503 , and an active locking tooth 505 is provided on one side of the rotating gear disc 506 . The active locking tooth 505 cooperates with the driven locking tooth 513 .

[0040] A rotating hole cooperating with the fixed shaft 514 is provided in the middle of the rotating gear plate 506, and a pin groove 512 is provided on the side wall of the rotating hole. A rotating shaft 510 cooperating with the rotating hole is provided on one side of the knob plate 507, and a pin block cooperating with the pin groove 512 is provided on the side wall of the rotating shaft 510.

[0041] The active locking teeth 505 and the driven locking teeth 513 are both annular structures. The cooperation principle between the two is similar to that of a ratchet pawl, and can realize automatic locking of the rotating toothed disc 506. After adjustment, the inner grille is placed in a rotational position.

[0042] A knob block 509 is provided on one side of the knob plate 507 .

[0043] The driving box 501 is a structure with one side open, and a clearance hole 515 that cooperates with the rotating gear disc 506 is provided on the side wall of the driving box 501.

[0044] A sliding groove 301 is provided on the inner side of the inner grille 3 , and the sliding groove 301 is an arc-shaped structure.

[0045] During adjustment, the rotating toothed disc 506 is driven to rotate by turning the knob block 509, and the rotating toothed disc 506 drives the inner grille 3 to rotate through the driven gear 511 to achieve angle adjustment of the inner grille 3. After the rotation is completed, the driven locking tooth 513 on the stopping disc 503 can lock the active locking tooth 505 to prevent the rotating toothed disc 506 from rotating. When reset is required, the knob disc 507 is pressed, the rotating shaft 510 presses the stopping disc 503 down, the reset spring 502 is compressed, and the stopping disc 503 is separated from the rotating toothed disc 506. At this time, the rotating knob block 509 drives the rotating toothed disc 506 to rotate in the opposite direction to achieve the reset process of the inner grille 3.

[0046] Example 2:

The drive box 501 is provided with a motor 9, and the output shaft of the motor 9 is connected to the rotating gear disc 506. The edge of the inner grille 3 is provided with driven teeth that engage with the rotating gear disc 506.

[0048] The motor 9 drives the rotating gear disc 506 to rotate, thereby driving the inner grille to rotate, thereby achieving adjustment of the wind direction, and the adjustment method is more convenient and quick.

[0049] The rest of the structure is the same as that of the first embodiment.

[0050] Example 3,

[0051] like Figure 8 As shown, the adjustment mechanism 5 includes a rack rod 8, one end of which is provided with a mating tooth 802, and the edge of the inner grille 3 is provided with a driven tooth engaged with the mating tooth 802, and the other end of the rack rod 8 is provided with a hand pull block 801, which is set on the casing of the air conditioner outdoor unit. By manually sliding the hand pull block 801 to pull the rack rod 8, the rack rod 8 drives the inner grille 3 to rotate, thereby realizing wind direction adjustment. The adjustment mechanism has low manufacturing cost and low maintenance cost.

[0052] The rest of the structure is the same as that of the first embodiment.

[0053] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
