Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0046] Figure 1 This is a schematic partial structural diagram of an air conditioner indoor unit according to an embodiment of the present invention, as shown below. Figure 1 As shown, and refer to Figures 2 to 7 This utility model provides an indoor air conditioner unit, which includes a housing, a front panel 200, and at least one drive mechanism.

[0047] The housing includes a front housing 100 and a rear housing, with an opening on the front side of the rear housing and an air inlet 110 formed on the front housing 100. The front panel 200 is rotatably mounted on the front housing 100 via at least one rotating arm 500. A drive mechanism is located inside the front housing 100; each drive mechanism corresponds to one rotating arm 500, and each drive mechanism includes a gear assembly 300 and a motor 400. The motor 400 drives the corresponding rotating arm 500 to rotate via the gear assembly 300, thereby causing the front panel 200 to open or close the air inlet 110.

[0048] In this embodiment, the front shell 100 is mounted on the rear shell to cover the front opening of the rear shell. One end of each rotating arm 500 is fixedly connected to or integrally formed with the front panel 200, and the other end of each rotating arm 500 is provided with a rotating shaft 550. The front panel 200 is mounted on the front shell 100 via at least one rotating arm 500. When there are two or more rotating arms 500, the number of drive mechanisms can be less than the number of rotating arms 500, or the number of drive mechanisms can be equal to the number of rotating arms 500, that is, the drive mechanisms are arranged in a one-to-one correspondence with the rotating arms 500. In other words, in this embodiment, only some of the rotating arms 500 can be connected to the drive mechanism, or each rotating arm 500 can be connected to the drive mechanism. The motor 400 of the drive mechanism can be mounted on the front shell 100 or the rear shell.

[0049] The design of the indoor unit of this air conditioner combines practicality and aesthetics. Through flexible air inlet 110 control and efficient cooling cycle, it provides users with a more comfortable, energy-saving, and easy-to-maintain air conditioning experience. The design of the front panel 200 allows it to cover the air inlet 110 when not in use, thus keeping the indoor unit neat and aesthetically pleasing. By controlling the opening and closing of the front panel 200 through a drive mechanism, users can adjust the size of the air inlet 110 as needed, thereby precisely controlling airflow and heat exchange efficiency. This helps reduce unnecessary energy waste and improve the air conditioner's energy efficiency ratio. Users can easily clean and maintain the indoor unit; when it is necessary to clean the indoor heat exchanger or replace the filter, users can easily open the front panel 200 to perform the operation.

[0050] In this embodiment, the front panel 200 is rotatably mounted onto the front housing 100 via a rotating arm 500. The drive mechanism includes a gear assembly 300 and a motor 400. The motor 400 drives the gear assembly 300 to rotate, thereby driving the rotating arm 500 to open or close the front panel 200 and the air inlet 110. Compared with existing technologies, the drive mechanism in this embodiment has a simple and compact structure, requires less installation space, and is easy to assemble.

[0051] Furthermore, compared to existing linkage drives, gear drives offer significant advantages in transmission efficiency, precision, load-bearing capacity, and operational reliability. Specifically, gear drives boast high transmission efficiency, thanks to the large contact area and low frictional loss during gear meshing, as well as their compact structure, which reduces energy loss during transmission. Gear manufacturing processes ensure high precision, resulting in high gear meshing accuracy. Gear drives can withstand large torques and loads, thus guaranteeing transmission stability and accuracy. Gear drives are reliable and have a long service life. Their stability and accuracy enable them to maintain stable transmission performance under prolonged, high-load operating conditions.

[0052] like Figure 5As shown, in some embodiments of this utility model, one end of each rotating arm 500 is fixedly connected to the front panel 200, and the other end is provided with a rotating shaft 550. The rotating shaft 550 can be integrally formed with or fixedly connected to the rotating arm 500.

[0053] In some embodiments of this utility model, one end of each rotating arm 500 is integrally formed with the front panel 200, and the other end is provided with a rotating shaft 550. The rotating shaft 550 can be integrally formed with the rotating arm 500 or fixedly connected to it. The integral formation of the rotating arm 500 with the front panel 200 can increase the connection between the rotating arm 500 and the front panel 200.

[0054] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the gear assembly 300 includes two or more gears, with adjacent gears meshing with each other. Among the two or more gears, the gear closest to the rotating arm 500 is fixedly connected to the rotating shaft 550 of the rotating arm 500, and the gear farthest from the rotating arm 500 is fixedly connected to the motor 400.

[0055] In this embodiment, the gear assembly 300 constitutes a gear transmission system. The motor 400 is connected to the gear transmission system via its output shaft, converting electrical energy into mechanical energy to drive the gears to rotate. Adjacent gears transmit torque and rotational motion through meshing. For example, when the gear assembly 300 includes two gears, these two gears are a first gear 310 and a second gear 320, respectively. The first gear 310 is connected to the rotating shaft 550 of the rotating arm 500, and the second gear 320 is connected to the rotating shaft of the motor 400.

[0056] The number of gears in the gear assembly 300 has a significant impact on the transmission ratio, structural complexity, cost, efficiency, durability, and space occupation. Therefore, when designing the gear assembly 300, those skilled in the art can select an appropriate number and combination of gears based on the specific application scenario and requirements.

[0057] In some embodiments of this invention, the rotation axis of the front panel 200 is parallel to the lateral direction of the housing. That is, the rotation shaft 550 on the rotating arm 500 is arranged along the lateral direction of the housing. This embodiment is particularly suitable for situations where the indoor unit of the air conditioner is a wall-mounted or recessed unit.

[0058] In some embodiments of this invention, the rotation axis of the front panel 200 is parallel to the vertical direction of the housing. That is, the rotation shaft 550 on the rotating arm 500 is arranged along the vertical direction of the housing.

[0059] like Figure 5As shown, in some embodiments of this utility model, each of the rotating arms 500 includes a first arm portion 530 and a second arm portion 540; a rotating shaft 550 is disposed on the second arm portion 520. The line connecting the two endpoints of the first arm portion 530 in the length direction is the first connecting line, and the line connecting the two endpoints of the second arm portion 540 in the length direction is the second connecting line. The angle between the first connecting line and the front panel 200 is 20 to 45 degrees, and the angle between the second connecting line and the first connecting line is 45 to 70 degrees. The length of the first connecting line is 1.2 to 2 times the length of the second connecting line.

[0060] For example, the angle between the first connecting line and the front panel 200 can be 20°, 25°, 30°, 40°, or 45°; preferably, the angle between the first connecting line and the front panel 200 is 25° to 30°. The angle between the second connecting line and the first connecting line can be 45°, 50°, 60°, 65°, or 70°; preferably, the angle between the second connecting line and the first connecting line is 65°. The length of the first connecting line can be 1.2 times, 1.4 times, 1.5 times, 1.8 times, or 2 times the length of the second connecting line; preferably, the length of the first connecting line can be 1.3 times the length of the second connecting line.

[0061] In this embodiment, the above-described configuration allows the front panel to have a large rotation angle, enabling it to open to a wider angle. This facilitates adjustment of the air intake volume and also makes it easier to perform maintenance on the indoor unit. Furthermore, the rotating arm in this embodiment, while having a large rotation angle, has a small size, requiring minimal installation space. This reduces manufacturing costs and simplifies assembly.

[0062] like Figure 5 As shown, in some embodiments of this utility model, the indoor unit of the air conditioner further includes a connecting assembly, and the rotating arm is connected to the front panel through the connecting assembly. The connecting assembly is integrally formed or fixedly connected to the rotating arm. The connecting assembly includes a plurality of first connecting plates 510 and second connecting plates 520. The first connecting plates 510 are perpendicular to or inclined to the front panel 200, and the second connecting plates 520 are parallel to the front panel 200. The plurality of first connecting plates 200 are spaced apart between the second connecting plates 520 and the front panel 200; a first arm portion 530 is disposed between the second connecting plates 520 and the second arm portion 540; the ratio of the cross-sectional area of ​​the first arm portion 530 to the cross-sectional area of ​​the second connecting plate 540 is 0.2 to 0.8. Through the above-mentioned arrangement, this embodiment can achieve a high bonding strength between the rotating arm and the front panel.

[0063] Furthermore, the integrated design of the connecting component and the rotating arm helps to further increase the bonding strength between the rotating arm and the front panel.

[0064] Furthermore, the connecting assembly also includes a third connecting plate, which is located on one side of the second connecting plate and is used to connect multiple first connecting plates together. Even further, the outer side of the third connecting plate is provided with reinforcing ribs. By providing the third connecting plate and reinforcing ribs, the connection stability between the front panel and the rotating arm can be further enhanced.

[0065] like Figure 3 , Figure 5 and Figure 7 As shown, in some embodiments of this utility model, the front shell 100 is provided with a first clearance hole 130 for the rotating arm 500 to pass through, so that the two ends of the rotating arm 500 are respectively located on the front and rear sides of the front shell 100. A mounting bracket 600 is provided on the rear wall of the front shell 100, and the mounting bracket 600 is provided with a mounting hole 610. The rotating shaft 550 is inserted into the mounting hole 610, and one end of the rotating shaft 550 is fixedly connected to or integrally formed with the rotating arm 500, while the other end extends out of the mounting hole 610.

[0066] Specifically, the axis of the mounting hole 610 is parallel to the axis of the rotating shaft 550, and the rotating shaft 550 is rotatably disposed in the mounting hole 610. The mounting bracket 600 can be a mounting plate or a mounting block. The function of the first clearance hole 130 is to provide rotation space for the rotating arm 500. In this embodiment, by providing the mounting bracket 600 on the inner side of the front housing 100, the front panel 200 can be rotatably mounted on the front housing 100. With the above arrangement, the installation or removal of the front panel 200 can be facilitated, thereby facilitating the maintenance of the internal components of the indoor unit.

[0067] In some embodiments of this utility model, the front housing 100 and the rear housing are detachably connected. Specifically, the front housing 100 and the rear housing can be connected by any feasible connection method, such as threaded connection, snap-fit ​​connection, plug-in connection, magnetic connection, etc. Among them, threaded connection includes bolt connection or screw connection. The detachable connection design of the front housing 100 and the rear housing has many advantages: it facilitates the assembly and disassembly of the indoor unit; during maintenance, users can easily disassemble the indoor unit, replace damaged parts or perform internal cleaning, and extend the service life of the indoor unit.

[0068] like Figure 2 , Figure 3 and Figure 7 As shown, in some embodiments of this utility model, the front housing 100 and the rear housing are detachably connected. Each drive mechanism is mounted on the front housing 100; the front housing 100 has a second clearance hole 140 for the gear assembly to pass through. The second clearance hole 140 provides rotational space for the gear.

[0069] In this embodiment, the drive mechanism is mounted on the front housing 100, which makes the structure of the drive mechanism more compact, thereby further reducing the installation space. Furthermore, this embodiment also facilitates the installation, inspection, and maintenance of the drive mechanism. Specifically, during installation, the drive structure can be first assembled onto the front housing 100, and then the front housing 100 can be installed onto the rear housing. During inspection or maintenance, the front housing 100 can be removed from the rear housing for inspection or maintenance of the drive mechanism.

[0070] In some embodiments of this example, the motor 400 can be directly mounted on the rear wall of the front housing 100.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments of this utility model, the indoor unit of the air conditioner further includes at least one mounting base 700. The mounting base 700 is provided in a one-to-one correspondence with the drive mechanism; each mounting base 700 is disposed on the rear wall surface of the front housing 100, and the motor 400 of each drive mechanism is mounted on the front housing 100 via the corresponding mounting base 700. In this embodiment, the motor 400 is mounted on the front housing 100 via the mounting base 700, which facilitates the installation or replacement of the motor 400 without damaging the front housing 100.

[0072] like Figure 7 As shown, in some embodiments of this utility model, each mounting base 700 has an arc-shaped mounting surface 710, and the motor 400 is mounted on the arc-shaped mounting surface 710. By setting the arc-shaped mounting surface 710, the contact area between the motor 400 and the mounting base 700 can be increased, thereby increasing the installation stability of the motor 400.

[0073] like Figure 3 and Figure 7 As shown, in some embodiments of this utility model, the motor 400 and the mounting base 700 are connected by screws or bolts, and threaded holes 720 are correspondingly provided on the side of the mounting base 700 and the housing of the motor 400.

[0074] like Figure 1 and Figure 2 As shown, in some embodiments of this utility model, an air outlet 120 is also formed on the front shell 100, and a heat exchange air duct connecting the air inlet 110 and the air outlet 120 is formed inside the casing; the air inlet 110 and the air outlet 120 are distributed in the vertical direction. In this embodiment, both the air inlet 110 and the air outlet 120 are located on the front side of the casing, which facilitates the embedded installation of the indoor unit in a cabinet or wall to meet the diverse usage needs of users.

[0075] In some embodiments of this utility model, there are two rotating arms 500, which are located on both sides of the air inlet 110 in the lateral direction. Compared with only one rotating arm 500, providing two rotating arms 500 makes the rotation process of the front panel 200 more stable.

[0076] Furthermore, one rotating arm 500 is connected to a drive mechanism, while the other rotating arm 500 is not connected to a drive mechanism. This configuration can reduce the production cost of the indoor air conditioning unit.

[0077] In some embodiments of this utility model, the air inlet 110 is located above the air outlet 120; the rotating arm 500 is disposed at the lower edge of the front panel 200. This arrangement prevents the intake airflow and the exhaust airflow from interfering with each other.

[0078] Furthermore, in some embodiments of this utility model, the lateral dimension of the air outlet 120 is smaller than the lateral dimension of the front housing 100. The lateral dimension of the air inlet 110 is smaller than the lateral dimension of the front housing 100. The lateral dimension of the front panel is equal to the lateral dimension of the front housing. The first clearance hole 130, the second clearance hole 140, the mounting base 700, and the mounting bracket 600 are all disposed on the outer side of the lateral dimension of the air outlet 120.

[0079] An embodiment of this utility model also provides an air conditioner, which includes an outdoor unit and an indoor unit as described in any of the above embodiments.

[0080] As the terminal device of the air conditioner's refrigeration system, the indoor unit of an air conditioner is mainly responsible for heat exchange with the user's space.

[0081] When the refrigeration system is operating in cooling mode, the refrigerant is compressed into a high-temperature, high-pressure gas in the compressor of the outdoor unit. After being cooled by the outdoor heat exchanger, it becomes liquid. The liquid refrigerant is then transported through the refrigerant pipe to the indoor heat exchanger of the indoor unit, where it evaporates and absorbs heat, carrying away the indoor heat. The refrigerant then returns to the compressor of the outdoor unit for circulation.

[0082] When the cooling system is in heating mode, the refrigerant is compressed into a high-temperature, high-pressure gas in the compressor of the outdoor unit and transported to the indoor heat exchanger of the indoor unit through the refrigerant pipe. After being cooled by the indoor heat exchanger, it becomes liquid, raising the indoor temperature. The liquid refrigerant is then transported to the outdoor heat exchanger of the outdoor unit through the refrigerant pipe, where it evaporates and absorbs heat before returning to the compressor for circulation.

[0083] Therefore, those skilled in the art should recognize that although many exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications conforming to the principles of the present invention can be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
