[0026] Currently, the sterilization modules built into air conditioners generally include high-voltage modules and positive and negative ion modules. When they are working, in addition to generating high-voltage electricity, they also generate a large number of electromagnetic interference signals. These interference signals usually couple to the iron control box first, and then interfere with the internal components of the control box, thereby affecting the normal operation of the air conditioner.

[0027] Based on this, the purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an air conditioner control box and an air conditioner, which can be grounded simply and effectively through metal connectors and grounding wires to reduce electromagnetic interference.

[0028] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution.

[0029] refer to Figures 1 to 3 , Figure 1 This is a side view of the electrical control box of an air conditioner during installation, according to an embodiment of this utility model. Figure 2 This is a front view of the electrical control box of an air conditioner during installation, as provided in this embodiment of the utility model. Figure 3 This is a schematic diagram of the grounding connection wire in the electrical control box of an air conditioner provided in this embodiment of the present invention. The electrical control box of an air conditioner provided in this embodiment includes: a metal box body 110, which houses an electrical control board; a metal connector 120 disposed on the outside of the metal box body 110; and a grounding connection wire 130 having a first end 131, a second end 132, and a third end 133. The first end 131 is connected to the metal connector 120, the second end 132 is connected to the electrical control board, and the third end 133 is connected to the grounding connector 140 in the air conditioner. The grounding connector 140 is grounded through a power grounding wire 170.

[0030] The metal housing 110 serves as the outer shell for housing the control board, protecting the internal electronic components from external environmental factors such as dust and moisture. Being made of metal, it also provides electromagnetic shielding and, after coupling with external electromagnetic interference, conducts the generated electromagnetic interference signals through the grounding connection line 130 to prevent them from entering the control box and affecting the control board's operation. The metal connector 120 is a conductive component located on the outside of the metal housing 110, serving as the physical and electrical connection point between the grounding connection line 130 and the metal housing 110. The metal connector 120 can be a metal insert welded to the side of the metal housing 110. Its design allows the first end 131 of the grounding connection line 130 to be clamped in place, ensuring good electrical contact and mechanical stability. This allows the control box to be grounded through existing grounding paths, eliminating the need for a separate additional grounding device, simplifying the installation process and improving efficiency.

[0031] In some embodiments, the grounding connection 130 can be a three- or four-terminal conductive wire, used to establish an electrical path from the control box to the existing grounding connection 140 in the air conditioner. The first end 131 is connected to the metal connector 120 to ensure that the metal box 110 can be grounded; the second end 132 is connected to the control board to ensure that the control board can also be grounded, thereby reducing the electromagnetic interference received by the control board; the third end 133 is connected to the grounding connection 140 in the air conditioner, and the grounding connection 140 can be a grounding screw, so that the entire control system can be reliably connected to the ground through the power grounding wire 170, effectively reducing the negative impact of electromagnetic interference on the system; in addition, the grounding connection 130 can also have a fourth end 134 for connecting second functional modules that do not have their own grounding connection 140, such as positive and negative ion modules and high voltage modules, to meet the grounding requirements of these modules.

[0032] The power grounding wire is part of the main power line of the air conditioner. It is used to connect the ground wire of the power system to the earth, providing a safe reference potential for the entire air conditioning system and ensuring that all live parts will not pose a risk of electric shock to users during normal operation. The power grounding wire can be connected to the first functional module with a large area of ​​metal structure in the air conditioner through a grounding screw. The grounding screw can be placed near the power input terminal to shorten the grounding path and reduce resistance.

[0033] In some embodiments, the grounding connector 140 may be a specific component in the air conditioner, such as a grounding screw on the outdoor heat exchanger 141, used to connect the third end 133 of the grounding connector 130 to form a grounding path. The connector is grounded through the power grounding wire 170, ensuring that all devices connected to it can safely conduct excess current or electromagnetic interference to the ground, protecting user safety and stable operation of the equipment.

[0034] It is understood that this application adopts a combined connection structure of a metal housing 110, a metal connector 120, and a grounding connection wire 130. The metal housing 110 houses the electronic control board, the metal connector 120 is disposed on the outside of the metal housing 110, and the grounding connection wire 130 has a first end 131, a second end 132, and a third end 133. The first end 131 connects to the metal connector 120, the second end 132 connects to the electronic control board, and the third end 133 connects to the grounding connector 140 in the air conditioner. With the above structure, during production and installation, only the first end 131, the second end 132, and the third end 133 of the grounding connection wire 130 need to be connected to the metal connector 120, the electrical control board, and the metal connector 120, respectively. This allows the electrical control box and its internal electrical control board to be indirectly grounded through the existing grounding connector 140 in the air conditioner, eliminating the need to reinstall the grounding connector 140 on the electrical control box. This not only avoids electromagnetic interference to the components inside the electrical control box but also effectively improves production and installation efficiency.

[0035] It is worth noting that the third terminal 133 is connected to the grounding connector 140 in the air conditioner. For example, connecting the plug on the control box to the evaporator with a screw can ensure that the electromagnetic interference signal in the control box can be conducted to the ground through the grounding wire.

[0036] In some embodiments, the control board is a PCB board that integrates a microprocessor or microcontroller. It can execute pre-programmed instructions to control the air conditioner's operating mode, temperature setting, fan speed, etc., and receive input signals from the user interface and environmental data provided by sensors to optimize the air conditioner's operating efficiency and comfort. Since the control board is in a complex electromagnetic environment, in this embodiment of the invention, the electromagnetic shielding effect of the control board is further enhanced by the combined use of the metal housing 110 and the grounding connection wire 130, thereby improving the system's anti-interference capability.

[0037] In some embodiments, the air conditioner includes a first functional module, and a grounding connector 140 is provided on the outside of the first functional module. The grounding connector 140 includes a grounding screw on the outside of the outdoor heat exchanger 141. It is understood that one end of the grounding connection wire 130 is inserted into the metal connector 120, and the other end is connected to the screw position on the outdoor heat exchanger 141 by a screw. Figure 2 As shown, this location can also have multiple screw holes for grounding other modules in the air conditioner, and this location can be grounded via a power grounding wire 170.

[0038] It is worth noting that the first functional module is externally equipped with a grounding screw, which serves as one end connection point of the grounding connection wire 130. This allows the grounding connection wire 130 to be directly fixed to the outdoor heat exchanger 141 by screwing, thus achieving common grounding for the electrical control box and the outdoor heat exchanger 141. To accommodate other air conditioning modules that may require additional grounding, multiple screw holes are reserved at this location. These additional screw holes can be used to connect other components inside the air conditioner, ensuring that all necessary parts can be reliably grounded, thereby guaranteeing the safety and stability of the entire air conditioning system.

[0039] In some embodiments, the air conditioner further includes a second functional module. The second functional module does not have a grounding connector 140 on its outer side. The grounding connector 130 also has a fourth end 134, which is used to connect to the grounding wire 160 of the second functional module to achieve air connection. The fourth end 134 can be a detachable quick-plug interface. It is understood that traditional grounding methods usually require fixing the grounding wire to a metal surface by screwing. Air connection is to provide a convenient grounding port to other modules in the air conditioner, so as to facilitate the connection of other modules that do not have a grounding connector 140 on their outer side.

[0040] The grounding wire for the second functional module refers to the grounding path designed for modules in the air conditioner that do not have built-in grounding connections, such as positive and negative ion modules and high-voltage modules. These modules may generate high electromagnetic interference or voltage during operation, so it is necessary to safely conduct their electrical noise and excess current to the ground through a grounding wire.

[0041] In some embodiments, the grounding wire of the second functional module adopts a quick-plug interface. In order to further reduce electromagnetic interference, the grounding wire of the second functional module can be a shielded cable. The shielding layer can not only protect the internal wires from interference from external electromagnetic waves, but also conduct the electromagnetic radiation generated by the module to the ground.

[0042] In some embodiments, the metal connector 120 includes a metal tab welded to a first side of the metal housing 110. The first side is the side of the metal housing 110 closest to the first functional module, so as to facilitate the connection between the metal housing 110 and the first functional module. It can be understood that the first side is the side of the metal housing 110 closest to the first functional module. Welding the metal tab at this position can not only shorten the wiring distance between the metal housing 110 and the first functional module, but also utilize the low impedance characteristics of the outdoor heat exchanger 141 to provide better conduction of electromagnetic radiation generated by the module to the ground.

[0043] In some embodiments, the metal insert is an L-shaped insert, with the first connecting portion and the second connecting portion of the metal insert set at an angle. The first connecting portion is close to the first side, and the second connecting portion is inserted into the first end 131 of the grounding connection wire 130. The first end 131 includes a clamping opening formed by two clamping pieces corresponding to the second connecting portion, which is used to clamp the second connecting portion for fixation. It can be understood that this L-shaped design increases the flexibility and stability of the connection, so that the grounding connection wire 130 can be firmly fixed on the metal insert. One end of the grounding connection wire 130 can be quickly plugged in and out by clamping the insert, that is, the grounding wire can be connected to the module without the use of tools. The design of the quick plug-in interface can improve the convenience of installation and maintenance, especially in places with limited space or difficult access. This interface can easily add or remove grounding connections without damaging the original structure.

[0044] In some embodiments, a socket plate 150 is provided on the second side of the metal box 110 adjacent to the first side. The socket on the socket plate 150 is electrofused to the control board. The second end 132 of the grounding connection line 130 is inserted into the socket. The second end 132 includes a plug corresponding to the socket, so as to ensure that the electromagnetic interference signal of the control board in the control box can be conducted to the ground through the grounding wire. It can be understood that through the electrical connection between the second end 132 of the grounding connection line 130 and the control board, the electromagnetic interference signal generated by the control board can be conducted to the ground through the grounding wire, reducing the impact on other electronic devices and improving the stability of the system. Moreover, the design of the plug and socket makes the installation of the grounding connection line 130 simple and quick, without the need for complicated welding or screw fixing, thus improving production efficiency.

[0045] In some embodiments, the first functional module includes an outdoor heat exchanger 141 of the air conditioner. The outdoor heat exchanger 141 includes an evaporator. It is understood that the evaporator, as a large-area metal structure, has the characteristics of low impedance. Moreover, the evaporator is located close to the electrical control box, so the electrical control box and its internal electrical control board can be grounded effectively and simply through the grounding connection line 130 to reduce electromagnetic interference.

[0046] In some embodiments, the second functional module includes a positive and negative ion module and a high-voltage module of the air conditioner. The positive and negative ion module is a functional component in the air conditioner used for air purification. It generates positive and negative ions to neutralize particulate matter in the air, such as dust, pollen, and bacteria, thereby improving indoor air quality. When working, the module generates a high voltage to ionize air molecules and form charged ions. The high-voltage module is a key component that provides power support to the positive and negative ion module or other components that require high-voltage operation. It typically includes a boost circuit that can convert low-voltage DC power into high-voltage DC or AC power of several thousand volts. Due to its high operating voltage, it may generate strong electromagnetic interference. It is understood that the positive and negative ion module and the high-voltage module may not have their own grounding connector 140. The fourth end 134 of the grounding connector 130 is designed as a detachable quick-plug interface for easy installation and maintenance. This design allows these second functional modules to be easily connected without damaging the original structure so that the second functional modules are grounded.

[0047] In some embodiments, the grounding connector 140 includes a grounding screw, and the third end 133 of the grounding connector 130 includes a nut corresponding to the grounding screw. The grounding screw is a physical connection point for grounding in the air conditioner and can be installed on the metal casing of the air conditioner or the outdoor heat exchanger 141. As one end connection point of the grounding connector 130, the grounding screw provides a reliable electrical path by connecting to the earth, ensuring that excess current or electromagnetic interference can be quickly conducted to the earth. It is understood that the third end 133 of the grounding connector 130 in this application is designed as a corresponding nut, which can be fitted onto the grounding screw and tightened to achieve a firm electrical connection, so as to ensure good contact resistance and mechanical stability and prevent the connection from loosening or falling off.

[0048] It is worth noting that when replacement or repair is needed, the grounding connection wire 130 can be easily removed simply by loosening the nut, without the need for complicated tools or steps. The design of the grounding screw and nut can be adjusted according to different models of air conditioners to ensure compatibility with various specifications of grounding connection wire 130 and adapt to different application scenarios.

[0049] In some embodiments, the electrical control box is installed between the outdoor heat exchanger 141 and the fresh air inlet 180 of the air conditioner to make full use of the space inside the air conditioner without sacrificing performance.

[0050] In some embodiments, the grounding connection wire 130 has a first end 131, a second end 132, a third end 133, and a fourth end 134, all of which can be designed using common single-prong plugs, quick-connect plugs, screw collars, etc., so that during production and installation, only one end of the grounding connection wire 130 needs to be inserted into the metal connector 120 welded to the surface of the iron electrical control box, and the others are connected to the evaporator, the overhead connection, and the electrical control board, respectively. This not only avoids electromagnetic interference to the components inside the electrical control box, but also effectively improves production and installation efficiency.

[0051] In some embodiments, specifically, the first end 131 of the grounding connection wire 130 adopts a insert design, which can be inserted into a metal insert welded to the first side of the metal housing 110. It has a clamp formed by two clips for holding the second connection part of the metal insert, ensuring good electrical contact and stable mechanical fixation, allowing quick insertion and removal, and enabling connection without tools. The second end 132 of the grounding connection wire 130 is designed as a plug, which can be directly inserted into a socket on the socket plate 150. The socket plate 150 is located on the second side of the metal housing 110 adjacent to the first side. Its socket is electrofused to the control board through internal wiring. This plug and socket design ensures reliable electrical connection. The grounding connection 130 is designed to facilitate quick assembly and disassembly during production and maintenance. The third end 133 of the grounding connection 130 is equipped with a corresponding nut, which can be fitted onto the existing grounding screw in the air conditioner and tightened. The grounding screw is usually installed on large-area metal structures such as the outdoor heat exchanger 141, providing a stable grounding path. The combination of nut and screw ensures good electrical contact and mechanical stability, making it suitable for long-term use. The fourth end 134 of the grounding connection 130 is designed as a detachable quick-plug interface for connecting second functional modules that do not have their own grounding connector 140. This quick-plug interface can achieve "air docking" without damaging the original structure, improving the flexibility of installation and maintenance.

[0052] In some embodiments, the quick-plug interface at the second end is used to quickly and conveniently connect and disconnect electrical or mechanical connections. In the electrical control box design of the air conditioner in this application, the quick-plug interface can be applied to various occasions such as grounding connection line 130, signal line, and power line to simplify the installation and maintenance process.

[0053] In some embodiments, for ease of installation and maintenance, the quick-plug interface at the second end can be a quick-plug interface corresponding to the grounding wire of the second functional module, which can easily achieve connection and disconnection without the use of tools. It is suitable for occasions where frequent maintenance or module replacement is required. For example: push-pull connector: connection and disconnection are achieved through simple push-in and pull-out operations, suitable for modules that require frequent plugging and unplugging; snap-on connector: quick locking and unlocking are achieved through a snap-on structure, which is simple to operate and has a low cost; spring-loaded connector: contact pressure is maintained by the force of a spring to ensure a good electrical connection, which is suitable for high-frequency plugging and unplugging applications.

[0054] In some embodiments, the present invention provides an outdoor unit of an air conditioner including the electrical control box of the air conditioner according to any of the above embodiments. It is understood that the electrical control box in the outdoor unit adopts a combined connection structure of a metal housing 110, a metal connector 120, and a grounding connection wire 130. The metal housing 110 houses the electrical control board, the metal connector 120 is disposed on the outside of the metal housing 110, and the grounding connection wire 130 has a first end 131, a second end 132, and a third end 133. The first end 131 is connected to the metal connector 120, and the second end 132 is connected to the electrical control board. The third end 133 is connected to the grounding connector 140 in the air conditioner. Based on the above structure, during production and installation, it is only necessary to connect the first end 131, the second end 132 and the third end 133 of the grounding connector 130 to the metal connector 120, the electrical control board and the metal connector 120 respectively. This allows the electrical control box and its internal electrical control board to be indirectly grounded through the existing grounding connector 140 in the air conditioner, without the need to reinstall the grounding connector 140 on the electrical control box. This not only avoids electromagnetic interference to the components inside the electrical control box, but also effectively improves production and installation efficiency.

Based on the above structure, during production and installation, only the first end 131, the second end 132 and the third end 133 of the grounding connector 130 need to be connected to the metal connector 120, the electrical control board and the metal connector 120 respectively. This allows the electrical control box and its internal electrical control board to be indirectly grounded through the existing grounding connector 140 in the air conditioner, without the need to reinstall the grounding connector 140 on the electrical control box.
