Abstract
Description
Technical Field
[0001] This application relates to the field of air conditioning technology, specifically providing an indoor air conditioning unit and an air conditioner. Background Technology
[0002] Air conditioner air deflectors are constantly exposed to airflow, making them prone to accumulating dust and breeding bacteria. This not only affects airflow quality but may also pose a potential threat to user health. Therefore, regularly cleaning the air deflectors or replacing them promptly when they malfunction is essential to ensuring the efficient and stable operation of air conditioners. This makes the disassembly of air deflectors a frequent occurrence during air conditioner maintenance.
[0003] However, there are significant safety hazards in the current disassembly of air conditioner air deflectors. Although most users know that the power should be turned off before disassembling electrical components, in practice, due to negligence or lack of relevant safety awareness, some users or after-sales personnel may rashly disassemble the air deflector without disconnecting the power. Air conditioners contain high-voltage components; if a live part is accidentally touched during disassembly, it could very likely cause an electric shock, posing a serious threat to personal safety.
[0004] Therefore, there is a need in the field for a new technical solution to address the above problems, which can automatically and reliably cut off the power to the air conditioning unit when the air deflector is removed, thereby providing a solid guarantee for the operational safety of users and after-sales personnel. Utility Model Content
[0005] This application aims to solve the aforementioned technical problem, namely, to address the issue that existing air conditioners, due to the lack of an effective power-off mechanism during the disassembly of the air guide plate, cause users or after-sales personnel to operate the equipment without disconnecting the power, thus posing a risk of electric shock.
[0006] In a first aspect, this application provides an indoor air conditioning unit, comprising:
[0007] The casing has mounting holes.
[0008] An air guide plate with a rotating shaft mounted on it;
[0009] The first and second conductive parts, which are independent of each other, are respectively connected to the electrical control circuit of the indoor unit of the air conditioner and extend into the mounting hole;
[0010] A third conductive part is disposed on the rotating shaft. When the rotating shaft is inserted into the mounting hole, the first conductive part and the second conductive part respectively contact the third conductive part, thereby forming a conductive circuit.
[0011] Optionally, the first conductive part and the second conductive part are both arc-shaped pieces and are distributed circumferentially along the inner wall of the mounting hole, and the third conductive part is a cylindrical structure.
[0012] Optionally, the indoor unit of the air conditioner further includes:
[0013] An insulating element is disposed within the mounting hole, the insulating element serving to isolate the first conductive portion and the second conductive portion.
[0014] Optionally, the insulating element is an insulating bushing, which is disposed on the inner wall of the mounting hole, and both the first conductive part and the second conductive part are disposed on the insulating bushing.
[0015] Optionally, the indoor unit of the air conditioner further includes:
[0016] A first elastic element and a second elastic element are both disposed within the mounting hole. The first elastic element is connected between the inner wall of the mounting hole and the first conductive part, and the second elastic element is connected between the inner wall of the mounting hole and the second conductive part.
[0017] Optionally, both the first elastic element and the second elastic element are insulating elastomers.
[0018] Optionally, the cross-sectional area of the cylindrical structure gradually decreases along the insertion direction of the rotating shaft.
[0019] Optionally, the third conductive part is a conductive ring, and multiple conductive rings are provided, which are spaced apart along the axial direction on the rotating shaft.
[0020] Optionally, multiple mounting holes and air guide plates are provided. Each mounting hole is provided with a set of independent first conductive parts and second conductive parts. Each air guide plate is provided with a third conductive part on its rotating shaft. The sets of first conductive parts and second conductive parts are electrically connected in series.
[0021] In a second aspect, this application provides an air conditioner including an indoor unit as described in any one of the first aspects.
[0022] By adopting the above technical solution, the air conditioner indoor unit provided in this application establishes independent first and second conductive parts within the mounting holes of the casing, which are connected in series to the air conditioner's electrical control circuit. Together with the third conductive part on the air guide plate's rotating shaft, they form a feedback mechanism, enabling real-time monitoring of the air guide plate's installation status. When the air guide plate is correctly installed, the three conductive parts form a closed loop, which the control system uses as the basis for allowing the entire unit to be powered on. When the air guide plate is removed, the loop is broken, triggering power-off protection. This design organically combines safety and ease of use, fundamentally preventing the risk of electric shock from uninterrupted operation while ensuring rapid power restoration during normal maintenance. This significantly improves product safety and user experience, simplifies safety management logic, and reduces after-sales maintenance costs.
[0023] The air conditioner provided in this application controls the power supply by monitoring the installation status of the air guide plate, greatly reducing the risk of electric shock caused by users or after-sales personnel neglecting to disconnect the power when disassembling the air guide plate. This establishes a reliable safety barrier for the operation process, significantly reducing the probability of accidents and protecting personnel safety. Furthermore, integrating the power-off mechanism into the air guide plate installation structure eliminates the need for additional complex operations, reducing equipment damage caused by misoperation, lowering after-sales maintenance costs and safety management difficulties, and enhancing the user experience and overall product competitiveness.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.
[0033] Please refer to Figure 1 , Figure 1 A partial structural diagram of an air conditioner indoor unit according to an embodiment of this application is shown. Specifically, the housing 1 of the air conditioner indoor unit is provided with a support portion 11, and a mounting hole 110 is provided on the support portion 11, in which the rotating shaft 21 of the air guide plate 2 is detachably installed.
[0034] Furthermore, a first conductive part 31 and a second conductive part 32, independent of each other, are provided in the mounting hole 110 of the housing 1. Both the first conductive part 31 and the second conductive part 32 are connected in series to a safety monitoring circuit in the overall electrical control circuit of the air conditioner indoor unit. This safety monitoring circuit generates an electrical signal based on the physical installation state of the air guide plate 2 and feeds this signal back to the main control system as the trigger for power-off protection. A third conductive part 33 is provided on the rotating shaft 21 of the air guide plate 2. When the air guide plate 2 is installed into the mounting hole 110 via its rotating shaft 21, the third conductive part 33 on the rotating shaft 21 will simultaneously make physical contact with the first conductive part 31 and the second conductive part 32 in the mounting hole 110, thereby forming a complete, closed current path. The state of this closed loop is continuously monitored by the air conditioning control system as a signal that the air guide plate 2 has been installed in place and the system allows the entire unit to be powered on.
[0035] The above solution establishes independent first conductive part 31 and second conductive part 32 within the mounting hole 110 of the housing 1, and connects them in series to a safety monitoring circuit. Together with the third conductive part 33 on the rotating shaft 21 of the air guide plate 2, they form a physical state feedback mechanism, enabling real-time monitoring of the installation status of the air guide plate 2. When the air guide plate 2 is correctly installed, a closed loop is formed, which the control system uses as the basis for allowing the entire unit to be powered on. When the air guide plate 2 is disassembled, the loop is broken, triggering the power-off protection. This design organically combines safety assurance with ease of use, fundamentally preventing the risk of electric shock from unpowered operation, and ensuring rapid power restoration during normal maintenance. This significantly improves product safety and user experience, while simplifying safety management logic and reducing after-sales maintenance costs.
[0036] In a specific implementation, the first conductive part 31 and the second conductive part 32 can be designed as positive and negative electrodes that are insulated from each other, and they are connected in series to the safety monitoring circuit via wires. When the third conductive part 33 (e.g., a metal conductive ring or other shaped conductor on the rotating shaft 21) is installed in place, it simultaneously contacts the positive and negative electrode contacts, forming a circuit in the safety monitoring circuit. The main control board uses this to determine that the air guide plate 2 is in place. Once disassembly causes the contact to break, the circuit is open, and the main control board immediately triggers relays and other devices to cut off the high-voltage main power supply circuit, thereby achieving power-off protection for the entire machine. This design can effectively isolate high-voltage risks and does not require manual intervention of the power switch, thus achieving automatic power-off protection before personnel come into contact with internal components.
[0037] In one specific embodiment, both the first conductive part 31 and the second conductive part 32 are designed as arc-shaped conductive sheets and are distributed circumferentially along the inner wall of the mounting hole 110. Correspondingly, the third conductive part 33, which is provided on the rotating shaft 21 of the air guide plate 2, is designed as a cylindrical structure that wraps around the outer circumference of the rotating shaft 21. When the rotating shaft 21 of the air guide plate 2 is inserted into the mounting hole 110, the third conductive part 33 can make full-circumferential covering contact with the circumferentially distributed first conductive part 31 and second conductive part 32. This contact method not only significantly increases the effective contact area and ensures the reliability of the conductive connection, but more importantly, it allows the air guide plate 2 to maintain a continuous conductive physical connection within the normal operating angle adjustment range (i.e., when the rotating shaft 21 rotates within the mounting hole 110), avoiding accidental power outages caused by momentary disconnection of contact due to the swing of the air guide plate 2.
[0038] Furthermore, along the insertion direction of the rotating shaft 21, the cross-sectional area of the cylindrical structure gradually decreases. When the rotating shaft 21 of the air guide plate 2 is inserted into the mounting hole 110, the front end of the cylindrical structure (the end with the smaller cross-sectional area) enters the mounting hole 110 first. Its gradually narrowing shape can more smoothly guide the rotating shaft 21 to be aligned. This structure can overcome slight deviations during initial assembly to improve the smoothness of the insertion of the rotating shaft 21.
[0039] In another specific embodiment, the third conductive part 33 disposed on the rotating shaft 21 of the air guide plate 2 adopts a design of multiple conductive rings, which are arranged at intervals along the axial direction of the rotating shaft 21. The axial distribution of multiple conductive rings is equivalent to setting multiple sets of parallel contact points on the rotating shaft 21. Even if individual conductive rings have poor contact due to dirt, slight deformation or local wear, the other conductive rings can still ensure that an effective conductive circuit is formed between the first conductive part 31, the second conductive part 32 and the third conductive part 33.
[0040] In one embodiment, an insulating element is also provided in the mounting hole 110. The insulating element is located between the first conductive part 31 and the second conductive part 32. The key function of the insulating element is to physically isolate the two conductive parts to prevent them from accidentally short-circuiting due to contact or foreign object contact, thus ensuring circuit safety.
[0041] One specific implementation involves providing an insulating bushing within the mounting hole 110, and fixing both the first conductive part 31 and the second conductive part 32 onto this insulating bushing. In this way, the insulating bushing provides a stable and mutually insulated mounting base for the two conductive parts, ensuring precise positioning and constant spacing, effectively preventing short-circuit risks caused by assembly errors or displacement of the conductive parts during long-term use.
[0042] In one embodiment, a first elastic element and a second elastic element are further provided within the mounting hole 110. The first elastic element is connected between the inner wall of the mounting hole 110 and the first conductive part 31, and the second elastic element is connected between the inner wall of the mounting hole 110 and the second conductive part 32. One end of the elastic element is fixed to the inner wall of the mounting hole 110 or a fixed structure (such as an insulating bushing) on the inner wall. The elastic pressure of the elastic element acts on the corresponding conductive part, so that both the first conductive part 31 and the second conductive part 32 can maintain a tight, low-resistance contact with the third conductive part 33 on the rotating shaft 21 when the air guide plate 2 swings, preventing signal interruption.
[0043] Furthermore, both the first and second elastic elements are insulating elastomers, whose insulating properties can block any potential conductive path formed through the elastic element itself, ensuring the integrity of electrical isolation within the mounting hole 110.
[0044] In one embodiment, the housing 1 has multiple mounting holes 110 for mounting corresponding air guide plates 2. Each mounting hole 110 has an independently provided set of a first conductive part 31 and a second conductive part 32, which are separate from each other. At the same time, each air guide plate 2 has a corresponding third conductive part 33 on its rotating shaft 21. Further, the first conductive parts 31 and the second conductive parts 32 in each set of mounting holes 110 are electrically connected in series, and finally connected to the safety monitoring circuit of the whole machine to form a continuous series link.
[0045] This series connection structure further reduces the risk of electric shock: the entire series circuit is only conductive when all air guide plates 2 are installed in place (i.e., the third conductive part 33 on the shaft 21 of each air guide plate 2 forms a partial circuit with the first conductive part 31 and the second conductive part 32 in its mounting hole 110). Once any air guide plate 2 is removed, its shaft 21 exits the mounting hole 110, causing the third conductive part 33 to lose contact with the corresponding first conductive part 31 and second conductive part 32, thus cutting off the partial circuit. Since all groups are connected in series, the breaking of any partial circuit will immediately make the entire series circuit open. Once this open circuit signal is detected by the electronic control system, it will immediately trigger a power outage in the main power circuit of the entire machine. Therefore, removing any air guide plate 2 will cause the entire machine to lose power. This greatly reduces the risk of live operation that may remain due to only removing part of the air guide plates 2, further providing safety protection for operators.
[0046] This application provides an air conditioner, including the indoor unit as described above. This air conditioner controls the power supply by monitoring the installation status of the air guide plate 2, significantly reducing the risk of electric shock caused by users or after-sales personnel neglecting to disconnect the power when disassembling the air guide plate 2. This establishes a reliable safety barrier during operation, greatly reducing the probability of accidents and protecting personnel safety. Furthermore, integrating the power-off mechanism into the air guide plate 2 installation structure eliminates the need for additional complex operations, reducing equipment damage caused by misoperation, lowering after-sales maintenance costs and safety management difficulties, and improving user experience and overall product competitiveness.
[0047] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments. Without departing from the principles of this application, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of this application.
