Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to an indoor air conditioning unit and an air conditioner. Background Technology

[0002] Currently, air conditioner indoor units typically use a single-axial flow fan layout. However, to meet the requirements of high air volume and low noise, the impeller diameter needs to be increased, resulting in a larger overall unit size. Furthermore, the single-axial flow arrangement suffers from uneven airflow, with high air velocity near the impeller and low velocity further away, leading to low heat exchange efficiency. To address this, related technologies have proposed a fan structure with multiple axial impellers connected in series. These impellers are typically positioned within the evaporator cavity, increasing airflow, reducing noise, and improving airflow uniformity and evaporator heat exchange efficiency without increasing motor speed or reducing fan diameter. However, assembling multiple impellers in series on a single shaft within the air guide ring of the air conditioner indoor unit is difficult. Utility Model Content

[0046] Currently, air conditioner indoor units typically use a single-axial flow fan layout. However, to meet the requirements of high air volume and low noise, the impeller diameter needs to be increased, resulting in a larger overall unit size. Furthermore, the single-axial flow arrangement suffers from uneven airflow, with high air velocity near the impeller and low velocity further away, leading to low heat exchange efficiency. To address this, related technologies have proposed a fan structure with multiple axial impellers connected in series. These impellers are typically positioned within the evaporator cavity, increasing air volume, reducing noise, and improving airflow uniformity and evaporator heat exchange efficiency without increasing motor speed or reducing fan diameter. However, connecting multiple impellers in series on a single shaft results in a large fan structure, making it difficult to assemble along the axial direction within the air guide ring of the indoor unit.

[0047] Based on this, this utility model proposes an indoor air conditioning unit, aiming to solve the problem of difficult installation of the fan impeller structure. Among other things, Figures 1 to 6 This is a schematic diagram of the structure of the indoor unit of the air conditioner according to this utility model.

[0048] Please see Figures 2 to 4 In one embodiment of the present invention, the indoor unit 100 of the air conditioner includes a fan structure 1 and an air guide structure 2. The fan structure 1 includes a rotating shaft 11 and a first fan 12 disposed on the rotating shaft 11. The air guide structure 2 includes a plurality of air guide parts 21. The plurality of air guide parts 21 can be assembled along the circumference of the rotating shaft 11 to form an air guide ring, so that the first fan 12 of the fan structure 1 can be laterally installed in the air guide ring.

[0049] In the technical solution of this utility model, by setting the rotating shaft 11 to install the first impeller 12, and by setting the first impeller 12 to rotate synchronously with the rotating shaft 11, the first impeller 12 can pressurize the airflow. By setting multiple air guides 21, the side of the air guide ring is opened before the first impeller 12 is installed, so that the first impeller 12 can be installed laterally in the air guide ring. After the first impeller 12 is installed, the multiple air guides 21 are gathered to form the air guide ring, so that the airflow can flow along the axial direction of the air guide ring. In this way, by setting multiple air guides 21, the air guide ring can be formed, and the first impeller 12 can be installed radially along the rotating shaft 11 in the air guide ring, thereby solving the problem of difficult installation of the impeller structure 1.

[0050] It should be noted that the air guide ring refers to a structure capable of forming an internal environment. This internal environment structure can accommodate the first impeller 12, and the air guide ring is an open structure with openings at both ends, allowing airflow to flow along its extension direction. Specifically, the number of air guides 21 is not limited; it can be two, three, four, or five, etc. This invention does not limit this. Specifically, two air guides 21 are provided, which allows the first impeller 12 to be installed laterally within the air guide ring and reduces errors caused by assembly gaps. Furthermore, the air guides 21 can be made of various materials. They can be metals such as iron and aluminum alloys, inorganic non-metallic materials such as nano-ceramics, or polymer materials such as plastics. Specifically, in this embodiment, the air guides 21 are made of plastic, which reduces the weight of the air guide structure 2 and facilitates molding.

[0051] It should also be noted that there are various ways to form the first impeller 12 and the rotating shaft 11. The first impeller 12 and the rotating shaft 11 can be integrally formed or separately formed, and this utility model does not limit this. Furthermore, the first impeller 12 includes at least one blade so that the first impeller 12 can rotate synchronously under the drive of the rotating shaft 11 to pressurize the airflow. Furthermore, the number of blades is not limited; it can be one, two, three, or four, etc., and this utility model does not limit this. Specifically, three blades are provided, and the three blades are spaced apart circumferentially along the rotating shaft 11, so that the number of blades can cover the circumference of the rotating shaft 11. This ensures that the impeller has a sufficient pressurization range and avoids increasing the forming difficulty of the impeller structure 1 due to an excessive number of blades, thus helping to reduce the manufacturing cost of the impeller structure 1.

[0052] In one embodiment of this utility model, please refer to Figures 4 to 6 The plurality of air guides 21 include a first air guide 211, and the air guide structure 2 also includes an air guide body 22 arranged in a ring. The first air guide 211 is disposed at one end of the air guide body 22 in the axial direction. The first air guide 211 and the air guide body 22 are integrally formed. In this way, by setting the air guide body 22, the first air guide 211 can be installed. At the same time, the first air guide 211 and the air guide body 22 are integrally formed, which can save subsequent assembly processes and eliminate errors caused by assembly gaps, thereby improving the accuracy of the air guide structure 2.

[0053] In one embodiment of this utility model, please refer to Figures 2 to 4 The plurality of air guides 21 include a first air guide 211. The air guide structure 2 also includes an air guide body 22 arranged in a ring. The first air guide 211 is located at one end of the air guide body 22 in the axial direction. A bearing 5 is provided on the air guide body 22. The end of the rotating shaft 11 is sleeved in the inner ring of the bearing 5. Thus, by providing the bearing 5, the wind turbine structure 1 can be rotatably installed in the air guide structure 2.

[0054] It should be noted that the above two related technical features, namely, "the first air guide part 211 is integrally formed with the air guide body 22" and "a bearing 5 is provided on the air guide body 22, and the end of the rotating shaft 11 is sleeved in the inner ring of the bearing 5", can be provided either one or both, and this utility model does not limit them.

[0055] In one embodiment of this utility model, please refer to Figures 2 to 5 The indoor unit 100 of the air conditioner also includes a mounting bracket 3, which defines a heat exchange cavity 31 with a first side opening for mounting the evaporator 9 of the indoor unit 100. Thus, by setting the mounting bracket 3, it is convenient to install the evaporator 9 and the heat exchange cavity 31 can be formed so that the evaporator 9 can exchange heat with the airflow in the heat exchanger.

[0056] It should be noted that the mounting bracket 3 can be made of various materials, such as metal or plastic, and this utility model does not limit the materials used.

[0057] Further, please refer to Figure 4 and Figure 5The plurality of air guides 21 include a first air guide 211, the first air guide 211 having a second side opening, the second side opening and the first side opening having the same orientation, the first air guide 211 being integrally formed with the mounting bracket 3. In this way, the integral forming can save subsequent assembly processes and eliminate errors caused by assembly gaps. At the same time, the first side opening and the second side opening having the same orientation allows the impeller structure 1 to be installed radially along the shaft 11 within the first air guide 211 and the mounting bracket 3.

[0058] In one embodiment of this utility model, please refer to Figures 1 to 3 The indoor unit 100 of the air conditioner also includes a sealing plate portion 4 disposed at the first side opening of the mounting bracket 3. At least a portion of the impeller structure 1 is disposed within the heat exchange chamber 31. Thus, by providing the sealing plate portion 4, the heat exchange chamber 31 is sealed and isolated, preventing the risk of frost formation on the indoor and outdoor panels 8 of the air conditioner. It should be noted that the sealing plate portion 4 can be made of various materials, such as rubber or plastic, as long as it can insulate the heat from the heat exchange chamber 31. This invention does not impose any limitations on this.

[0059] In one embodiment of this utility model, please refer to Figure 4 and Figure 6 The plurality of air guides 21 include a second air guide 212, which is disposed at one end of the sealing plate 4 in its length direction and is integrally formed with the sealing plate 4. In this way, the second air guide 212 and the sealing plate 4 are integrally formed, which can save subsequent assembly processes and eliminate errors caused by assembly gaps.

[0060] In one embodiment of this utility model, please refer to Figure 4 and Figure 5The indoor unit 100 of the air conditioner also includes a sealing plate portion 4 disposed at the first side opening of the mounting bracket 3. Two first splicing surfaces 32 are formed between the sealing plate portion 4 and the mounting bracket 3. The plurality of air guide portions 21 include a first air guide portion 211 and a second air guide portion 212. Two second splicing surfaces 2111 are formed between the first air guide portion 211 and the second air guide portion 212. Along the circumferential direction of the rotating shaft 11, each first splicing surface 32 and each second splicing surface 2111 are staggered. Thus, the staggered arrangement of the first splicing surface 32 and the second splicing surface 2111 allows the... The joint between the first air guide 211 and the second air guide 212 can be staggered from the joint between the mounting bracket 3 and the sealing plate 4. This can disperse stress, avoid stress concentration, and improve the strength of the connection. On the other hand, it can allow the first air guide 211 and the mounting bracket 3 to form a first stepped surface facing the first air guide 211, and the second air guide 212 and the sealing plate 4 to form a second stepped surface facing the sealing plate 4, so as to abut against the first stepped surface. This helps to quickly install the second air guide 212 onto the first air guide 211.

[0061] In one embodiment of the present invention, the indoor unit 100 of the air conditioner further includes a drive motor 6. The motor housing 7 of the drive motor 6 is disposed on the mounting bracket 3. The output main shaft of the drive motor 6 drives the end of the rotating shaft 11. Thus, by setting the drive motor 6, the rotating shaft 11 is driven to rotate, so that the fan wheel on the rotating shaft 11 can rotate synchronously to pressurize the airflow.

[0062] It should be noted that the bearing 5 and the drive motor 6 are respectively located on the air guide body 22 and the mounting bracket 3, while the air guide body 22, the first air guide part 211 and the mounting bracket 3 are integrally set, which can reduce the assembly error, improve the accuracy, and thus help to eliminate vibration noise.
