Description

Technical Field

[0001] This utility model relates to the field of air conditioner accessories technology, specifically an air conditioner end plate with sealing and noise reduction functions. Background Technology

[0002] Air conditioner end plates are an important component of the air conditioning unit's outer casing, typically located on the sides or front of the unit. They primarily serve the basic functions of structural support and enclosure, protecting core components such as the fan, heat exchanger, and compressor from external impacts. Furthermore, the design of the end plates directly affects the overall sealing and protection performance of the unit, effectively preventing dust and rainwater intrusion. Their appearance is also a significant factor influencing the overall aesthetics of the air conditioner.

[0003] Utility model patent CN215372896U discloses a household air conditioner end plate. This end plate includes an end plate body with a first sliding groove inside. An L-shaped locking rod is slidably connected inside the first sliding groove. A sliding plate is fixedly connected to the upper end of the L-shaped locking rod, and a first spring is fixedly connected to the outer surface of the sliding plate. One end of the first spring is fixedly connected to the end plate body. This household air conditioner end plate, through the cooperative arrangement of the L-shaped locking rod, sliding plate, and support plate, allows for easy installation during use. By pressing a control block, the locking block disengages from the groove, and then the support plate slides, causing the sliding plate and L-shaped locking rod to slide, compressing or stretching the first spring, adjusting the position of the L-shaped locking rod, and fixing the end plate. This facilitates the fixing of the end plate and improves its installation applicability.

[0004] The ventilation openings of this household air conditioner end plate are usually open or semi-open when the equipment is not in use, which cannot effectively prevent external pollutants such as dust and moisture from entering the machine, affecting the life and performance of the equipment. At the same time, the airflow noise is relatively direct when the equipment is running, and there is a lack of effective sound wave attenuation methods. In view of this, we propose an air conditioner end plate with sealing and noise reduction functions. Utility Model Content

[0005] The purpose of this utility model is to provide an air conditioning end plate with sealing and noise reduction functions to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An air conditioning end plate with sealing and noise reduction function includes a body, and an end plate structure is installed on the front end face of the body. The end plate structure includes an outer cover plate fixed to the body, a sealing component housed inside the outer cover plate, and a noise reduction component disposed inside the outer cover plate. The noise reduction component is located behind the sealing component. The sealing component consists of multiple blades arranged vertically, each blade being rotatably connected to the outer cover plate, and the multiple blades being linked together by a connecting rod. One of the blades is connected to a rotating motor that drives its rotation. The noise reduction component includes a frame fixed inside the outer cover plate, and several V-shaped guide plates are fixed inside the frame.

[0007] Preferably, the front end of the outer cover is a closed surface with an opening, and several ribs are fixed inside the opening; the rear end of the outer cover is open and fixedly connected to the machine body. In this setup, the reinforcing bars form a basic protective grid, which can initially block larger foreign objects from entering while ensuring ventilation.

[0008] Preferably, the front end of the inner side of the outer cover is fixed with a number of horizontally arranged lap plates; the number of lap plates is equal to that of the leaf plates and their positions correspond one-to-one; when the leaf plate rotates toward the corresponding lap plate, its edge overlaps the lap plate and keeps the leaf plate in a horizontal state. This setting provides a stable support point for the leaf plate when it is closed, ensuring that it can form a complete sealing plane.

[0009] Preferably, a fixing shaft is fixed to the rear edge of the page plate, and the two ends of the fixing shaft pass through the left and right side walls of the outer cover plate respectively and form a rotatable connection with the outer cover plate. This setting provides a reliable rotational fulcrum for the opening and closing movement of the leaf plate, ensuring the stability of the operation.

[0010] Preferably, the rotary motor is mounted on the outer side wall of the outer cover plate; the fixed shaft corresponding to the leaf plate connected to the rotary motor is coaxially fixed with the output shaft of the rotary motor; This setup enables direct power input, allowing the synchronous movement of the entire enclosed assembly to be controlled by driving a single leaf plate.

[0011] Preferably, the page plate has a through groove, and a fixing post is fixed in the through groove; the axis of the fixing post is parallel to the axis of the fixing shaft and passes through the connecting rod and is rotatably connected to the connecting rod; This setup creates a linkage mechanism between the page panels, ensuring that all page panels can rotate synchronously and have high consistency in their movements.

[0012] Preferably, the noise reduction component is located at the rear of the end plate structure; several transverse partitions are fixed inside the frame, which divide the interior of the frame into multiple independent installation spaces; the guide plate is vertically fixed inside the installation space. In this setup, the partitions regularly divide the internal space, which helps to organize and fix the noise reduction components in an orderly manner, making the structure compact.

[0013] Preferably, an air duct for airflow is formed between two adjacent guide vanes, and the air duct is bent. In this setup, the bent air duct can change and disrupt the direction of the airflow, thereby dispersing its energy and suppressing ventilation noise.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. The air conditioner end plate with sealing and noise reduction function, through the setting of movable sealing components, can completely seal the ventilation channel when the air conditioner is idle, forming an effective physical barrier, thereby preventing dust and moisture from entering the interior of the unit, improving the protective performance of the equipment and the convenience of maintenance during idle periods. 2. The air conditioner end plate with sealing and noise reduction function, through the noise reduction component with bent air duct, forces the airflow to change its direction and speed when passing through the end plate during air conditioner operation, disperses and consumes sound wave energy, achieves suppression of ventilation noise, and improves the quiet performance of the product.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figures 1-6 An air conditioning end plate with sealing and noise reduction functions includes a body 100, and an end plate structure 200 is installed on the front end face of the body 100. The end plate structure 200 includes an outer cover plate 210 fixed to the body 100, a sealing component 220 housed inside the outer cover plate 210, and a noise reduction component 230 disposed inside the outer cover plate 210. The noise reduction component 230 is located behind the sealing component 220, thus forming a multi-layer functional structure layout from front to back, which helps to achieve ventilation control and noise suppression in sequence.

[0018] like Figure 2 and Figure 3 As shown, in this invention, the front end of the outer cover plate 210 is a closed surface with an opening. Several ribs 211 are fixed inside this opening, forming a basic protective grid that can initially block larger foreign objects from entering. The rear end of the outer cover plate 210 is open and fixedly connected to the body 100. Several horizontally arranged support plates 212 are fixed inside the front end of the outer cover plate 210, providing reliable support points for the leaf plate 221 when closed.

[0019] like Figures 2-5 As shown, specifically, the enclosing assembly 220 consists of multiple leaf plates 221 arranged vertically. Each leaf plate 221 is rotatably connected to the outer cover plate 210, and a fixed shaft 2211 is fixed to its rear edge. Both ends of the fixed shaft 2211 penetrate the left and right side walls of the outer cover plate 210 respectively, forming a rotatable connection with the outer cover plate 210. A rotary motor 223 is mounted on the outer side wall of the outer cover plate 210. The fixed shaft 2211 corresponding to the leaf plate 221 connected to the rotary motor 223 is coaxially fixed to the output shaft of the rotary motor 223. This allows the rotary motor 223 to directly drive the leaf plate 221, thereby controlling the synchronous opening and closing of all leaf plates through a linkage mechanism.

[0020] Furthermore, the multiple leaf plates 221 are linked together by a connecting rod 222. A through groove 2212 is provided on each leaf plate 221, and a fixing post 2213 is fixed within the through groove 2212. The axis of the fixing post 2213 is parallel to the axis of the fixing shaft 2211, and it passes through the connecting rod 222, rotatably connecting to the connecting rod 222. This linkage mechanism ensures that the multiple leaf plates 221 can achieve a consistent rotation angle, resulting in high synchronization of actions. The number of overlapping plates 212 is equal to that of the leaf plates 221, and their positions correspond one-to-one. When a leaf plate 221 rotates towards its corresponding overlapping plate 212, its edge overlaps the overlapping plate 212, keeping the leaf plate 221 horizontal. At this time, all the leaf plates together form a continuous sealing plane, effectively blocking the passage of external dust and moisture.

[0021] like Figure 2 , Figure 3 and Figure 6 As shown, the noise reduction assembly 230 also includes a frame 231 fixed within the outer cover plate 210. Several transverse partitions 2311 are fixed inside the frame 231, which divide the interior of the frame 231 into multiple independent installation spaces. This division helps to organize and fix the internal noise reduction components, making the structure more regular.

[0022] like Figure 6 As shown, it is worth noting that the air deflector 232 is vertically fixed within the installation space of the frame 231. The air deflector 232 is V-shaped, and an air duct for airflow is formed between two adjacent air deflectors 232. The air duct is also bent, and this bent air duct design can change the airflow direction and effectively disperse the airflow energy, thereby suppressing ventilation noise.

[0023] It is worth noting that the rotating motor 223 involved in this utility model is a conventional technology and will not be described in detail here.

[0024] In this embodiment, the air conditioner end plate with sealing and noise reduction function works as follows: First, the rotating motor 223 receives a control signal and starts working. Then, the rotating motor 223 drives the directly connected blade 221 to rotate through the fixed shaft 2211. The movement of the blade 221 is transmitted to all other blades 221 through a linkage mechanism composed of the fixed column 2213 and the connecting rod 222, so that they rotate synchronously. Next, when the air conditioner needs ventilation, the blade 221 rotates and opens. The airflow passes through the rib 211 grid and the gap between the blades 221 in sequence, and then enters the bent air duct composed of the guide plate 232. During this process, the noise of the airflow is attenuated. Finally, when the air conditioner stops working, the rotating motor 223 drives the blade 221 to rotate in the opposite direction until it overlaps the mounting plate 212 to form a sealing surface, thereby preventing dust and moisture from the external environment from entering the interior of the unit 100.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
