Description

Technical Field

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

[0002] Air conditioners typically have a controller installed in both the indoor and outdoor units. When the controller on the outdoor unit is operating, it generates Joule heat due to the current. Outdoor air, after heat exchange with the condenser, then passes through the controller's cooling fins, cooling the controller itself. However, when the air conditioner is in cooling mode and the outdoor temperature is high, the temperature of the air passing through the condenser increases significantly, reducing its cooling effect on the controller. To protect the controller, the machine must reduce its operating frequency. This creates a conflict between the cooling demand and the controller's frequency limitation when the controller temperature is too high, thus affecting the air conditioner's cooling capacity. Utility Model Content

[0004] The solution to the technical problem of this utility model is: an installation structure, which includes an indoor unit and an electrical control box. The indoor unit includes a housing and a fan assembly disposed within the housing. The fan assembly is used to draw indoor air into the housing. The electrical control box includes a housing, an outdoor unit electrical control board, and a radiator. The housing is disposed on one side of the housing, the outdoor unit electrical control board is disposed within the housing, and the radiator is disposed on the outdoor unit electrical control board. The radiator extends into the housing and is disposed on the air inlet side of the fan assembly.

[0005] The beneficial effects of this invention are as follows: the fan assembly draws in indoor air, performs heat exchange and temperature regulation, and then outputs it back into the room, achieving air circulation and temperature regulation; the outdoor unit's electronic control board controls the rotation speed of the outdoor unit itself, thereby regulating the air conditioner; the outdoor unit's electronic control board generates heat during operation, and the radiator on the board, extending into the casing and located on the air intake side of the fan assembly, can directly utilize fresh air to cool the radiator. As the fresh air flows through the radiator, it carries away the heat, thus cooling the outdoor unit's electronic control board. By employing indoor air cooling, utilizing the relatively comfortable indoor ambient temperature to cool the radiator, higher heat dissipation efficiency is achieved, better meeting the heat dissipation needs of the outdoor unit's electronic control board. This eliminates the need for the air conditioner to reduce its frequency in hot weather, improving cooling capacity and user comfort.

[0006] As a further improvement to the above technical solution, a mounting groove is formed on one side of the wind turbine assembly on the outer shell. The mounting groove includes a groove top and at least two groove walls. The electrical control box is supported on the groove top. The lower end of each groove wall is connected to the groove top, and at least two groove walls are connected to each other.

[0007] As a further improvement to the above technical solution, the electrical control box also includes an electrical control mounting box disposed within the box body. The outdoor unit electrical control board is disposed within the electrical control mounting box and is fastened to the electrical control mounting box by screws. The electrical control mounting box is mounted on the box body by screws. The electrical control mounting box is provided with a third through hole, through which the radiator passes.

[0008] As a further improvement to the above technical solution, the electrical control mounting box is provided with a buckle, and the inner wall of the box is provided with a slot, and the buckle engages with the slot.

[0009] As a further improvement to the above technical solution, the electrical control box also includes a cover plate, on which an arched limiting part is provided, which is used to engage with the box body.

[0011] As a further improvement to the above technical solution, the box body is provided with a second through hole, which is corresponding to the first through hole, and the heat sink passes through the second through hole and the first through hole in sequence.

[0012] As a further improvement to the above technical solution, the installation structure also includes a sealing strip, which is disposed between the box body and the outer shell, and surrounds the first through hole and the second through hole.

[0013] An air conditioner includes an outdoor unit body and an installation structure as described in any of the above claims, wherein the outdoor unit control board is electrically connected to the outdoor unit body.

[0014] As a further improvement to the above technical solution, the outdoor unit's control board is electrically connected to the outdoor unit body and is used to control the operation of the outdoor unit body. The outdoor unit body does not have an independent control board, but only retains the actuators.

[0019] To more clearly illustrate the technical solutions in the embodiments of this utility model, the drawings used in the description of the embodiments have been briefly explained above. Obviously, the described drawings are only a part of the embodiments of this utility model, not all of them.

[0020] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages mentioned herein do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0021] An air conditioner typically has a controller installed on both the indoor and outdoor units 100. When the controller on the outdoor unit 100 is operating, it generates Joule heat due to the current. Outdoor air, after heat exchange with the condenser, then passes through the controller's cooling fins, cooling the controller itself. However, when the air conditioner is in cooling mode and the outdoor temperature is high, the temperature of the air exchanged with the condenser increases significantly, reducing its cooling effect on the controller. To protect the controller, the machine must reduce its operating frequency. This causes a conflict between the cooling demand and the controller's frequency limitation when the controller temperature is too high, thus affecting the air conditioner's cooling capacity.

[0022] Therefore, this utility model proposes an installation structure, referring to... Figures 1-3 The device includes an indoor unit and an electrical control box 200. The indoor unit includes a housing 110 and a fan assembly 120 disposed within the housing 110. The fan assembly 120 is used to draw indoor air into the housing 110. The electrical control box 200 includes a housing 210, an outdoor unit electrical control board 220, and a radiator 230. The housing 210 is disposed on one side of the housing 110. The outdoor unit electrical control board 220 is disposed within the housing 210. The radiator 230 is disposed on the outdoor unit electrical control board 220 and extends into the housing 110 and is disposed on one side of the fan assembly 120.

[0023] The fan assembly 120 draws in indoor air, performs heat exchange and temperature regulation, and then outputs it back into the room, achieving air circulation and temperature regulation. The outdoor unit control board 220 controls the rotation speed of the outdoor unit 100, etc., to regulate the air conditioner. The outdoor unit control board 220 generates heat during operation. The radiator 230 on the outdoor unit control board 220 extends into the outer casing 110 and is located on the air intake side of the fan assembly 120, allowing direct cooling using fresh air. As the fresh air flows through the radiator 230, it carries away the heat, thus cooling the outdoor unit control board 220. By employing indoor air cooling, utilizing the relatively comfortable indoor ambient temperature to cool the radiator 230, higher heat dissipation efficiency is achieved, better meeting the heat dissipation needs of the outdoor unit control board 220. This eliminates the need for the air conditioner to reduce its frequency in hot weather, improving cooling capacity and user comfort.

[0024] The electrical control box 200 and housing 210 are securely installed on the side of the indoor unit casing 110, ensuring their airtightness to prevent the intrusion of moisture and dust. The casing 110 has an air inlet and an air outlet. When the air conditioner is running, the fan assembly 120 drives indoor air into the casing 110 through the air inlet, adjusts the temperature according to the air conditioner's operating mode, and then exhausts the air through the air outlet. The heat generated by the outdoor unit's electrical control board 220 is conducted to its surface through a radiator 230 connected using a high thermal conductivity material. The radiator 230 is designed with fins or heat pipes, extending into the casing 110 and located on the air inlet side of the fan, prioritizing heat dissipation. Heat is absorbed by unconditioned fresh air; fresh flowing air or circulating air comes into direct contact with the surface of radiator 230, carrying away heat through heat convection and heat conduction, forming a heat dissipation path of "outdoor unit control board 220 → radiator 230 → air"; taking advantage of the relatively suitable indoor temperature environment, the temperature difference of radiator 230 increases, thereby improving the efficiency of heat exchange; in high-temperature environments, the temperature of outdoor unit control board 220 remains stable, so that the air conditioner does not need to reduce its operating frequency, thereby increasing the cooling capacity; the control box 200 adopts an independent design, which can be quickly disassembled and replaced in case of failure, thereby reducing maintenance costs.

[0025] The electrical control box 200 is prone to loosening of its fixing points due to long-term vibration from air conditioning operation, posing a risk of detachment. Therefore, in one embodiment, a mounting groove 130 is formed on one side of the impeller assembly 120 on the outer casing 110. The mounting groove 130 includes a groove top 131 and at least two groove walls 132. The electrical control box 200 is supported on the groove top 131, and the lower end of each groove wall 132 is connected to the groove top 131. At least two groove walls 132 are connected to each other. By designing a dedicated mounting groove 130 on the outer casing 110, the electrical control box 200 can be installed on the indoor unit more neatly and aesthetically. The groove wall 132 of the mounting groove 130 provides support for the electrical control box 200, increasing its structural stability. At least two groove walls 132 are connected to each other, forming a relatively enclosed space to prevent the electrical control box 200 from shaking or shifting during installation and use. The lower end of the groove wall 132 is connected to the groove top 131 to ensure that it can withstand the weight of the electrical control box 200 and the vibration that may be generated during operation.

[0026] When the air conditioner is running, the vibrations of components such as the compressor and fan are directly transmitted to the outdoor unit's electrical control board 220, which may cause solder joints to crack and capacitors to detach. Therefore, in one embodiment, the electrical control box 200 further includes an electrical control mounting box 240 disposed within the housing 210. The outdoor unit's electrical control board 220 is disposed within the electrical control mounting box 240 and is fastened to the electrical control mounting box 240 with screws. The electrical control mounting box 240 is mounted to the housing 210 with screws. The electrical control mounting box 240 has a third through hole 242 through which the radiator 230 passes. The electrical control mounting box 240 can accommodate and fix the outdoor unit electrical control board 220. The installer only needs to place the outdoor unit electrical control board 220 in the electrical control mounting box 240 and then fix it with screws, which improves the installation efficiency and reduces the error rate that may occur during the installation process. The electrical control mounting box 240 provides an additional protective layer for the outdoor unit electrical control board 220, which can alleviate the impact of external factors such as vibration and shock on the outdoor unit electrical control board 220 and protect it from damage.

[0027] Fixing the mounting box solely with screws or brackets requires additional alignment of holes and tightening of screws, resulting in a lengthy installation time. Therefore, in one embodiment, the electrical control mounting box 240 is equipped with a buckle 241, and the inner wall of the box body 210 is provided with a slot 211, with the buckle 241 engaging with the slot 211. The engagement of the buckle 241 and the slot 211 makes the installation of the electrical control mounting box 240 simpler and faster, improving installation efficiency and reducing installation difficulty and cost. The tight fit between the buckle 241 and the slot 211 ensures a stable connection between the electrical control mounting box 240 and the box body 210, providing good shock resistance and effectively preventing loosening or detachment of the electrical control mounting box 240 during use, thereby ensuring the stability of the electrical control system.

[0028] Dust, fluff, and other particulate matter may directly adhere to the surface of the outdoor unit's electrical control board 220, causing short circuits or poor heat dissipation. Therefore, in one embodiment, the electrical control box 200 further includes a cover plate 250, which has an arched limiting part 251 for engaging with the housing 210. The cover plate 250 covers the opening of the housing 210, thereby protecting the outdoor unit's electrical control board 220 and other internal components from external environmental factors such as dust and moisture. The engagement of the arched limiting part 251 with the housing 210 allows the cover plate 250 to be easily disassembled and installed. When the outdoor unit's electrical control board 220 malfunctions or requires maintenance, maintenance personnel can quickly open the cover plate 250 to inspect and repair the board, reducing maintenance time and improving maintenance efficiency.

[0029] Insufficient heat dissipation may trigger over-temperature protection, causing the air conditioner to shut down frequently. Therefore, in one embodiment, the outer casing 110 is provided with a first through hole 111, which is located on one side of the impeller assembly 120. The radiator 230 extends into the outer casing 110 through the first through hole 111. By allowing the radiator 230 to extend into the outer casing 110 through the first through hole 111 and directly contact the airflow on the side of the impeller assembly 120, the contact area between the radiator 230 and the airflow can be significantly increased. This helps to reduce the operating temperature of the outdoor unit's electronic control board 220, improve its stability and reliability, and thus extend the service life of the air conditioner.

[0030] The housing 110 and box 210 contain various components and wiring layouts. During installation, the radiator 230 may be interfered with by other structures within the housing 110 or box 210. Therefore, in one embodiment, the box 210 is provided with a second through hole 212, which corresponds to the first through hole 111. The radiator 230 passes through the second through hole 212 and the first through hole 111 sequentially. By allowing the radiator 230 to pass through the second through hole 212 and the first through hole 111 sequentially, the airflow between the radiator 230 and the interior of the housing 110 is kept unobstructed. This allows the radiator 230 to more effectively absorb and dissipate the heat generated by the outdoor unit's electrical control board 220, thereby improving heat dissipation efficiency. The corresponding arrangement of the second through hole 212 and the first through hole 111 ensures that the radiator 230 will not be interfered with by other structures within the housing 110 or box 210 during installation, simplifying the installation process and reducing the risk of installation errors.

[0031] Dust can freely enter the electrical control box 200 through the first through hole 111 and the second through hole 212. Over time, dust will gradually accumulate on components such as the outdoor unit electrical control board 220 and the radiator 230. Therefore, in one embodiment, the mounting structure also includes a sealing strip, which is disposed between the housing 210 and the outer casing 110, and surrounds the first through hole 111 and the second through hole 212. By surrounding the first through hole 111 and the second through hole 212, it can be ensured that the sealing strip can fit tightly against the housing 210 and the outer casing 110 at any position, thereby enhancing its sealing performance. The sealing strip can effectively prevent external factors such as dust and moisture from entering the electrical control box 200 through the first through hole 111 and the second through hole 212, protecting internal components such as the outdoor unit electrical control board 220 from contamination and corrosion, and improving the reliability of the entire air conditioning system.

[0032] An air conditioner includes an outdoor unit body 100 and an installation structure as described in any of the preceding claims, wherein the outdoor unit control board 220 is electrically connected to the outdoor unit body 100.

[0033] The outdoor unit control board 220 is electrically connected to the outdoor unit body 100 and is used to control the operation of the outdoor unit body 100. The outdoor unit body 100 does not have an independent control board, but only retains the actuator. The actuator is directly connected to the outdoor unit control board 220 in the control box 200 via a power cable, thereby realizing the control of the outdoor unit body 100. The direct connection between the control box 200 and the actuator of the outdoor unit body 100 via a power cable eliminates the risk of communication failure between the indoor and outdoor units, and improves the stability and reliability of the system. The outdoor unit body 100 without an independent control board has a simpler structure, which helps to reduce the complexity and maintenance difficulty of the system, making the system debugging and maintenance easier and faster.

[0034] Preferably, the indoor unit further includes an indoor unit electrical control board, and the indoor unit electrical control board and the outdoor unit electrical control board 220 are integrated into the electrical control box 200.
