Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and more specifically, to an electronic control component, an outdoor unit, and an air conditioner. Background Technology

[0002] With the continuous development of the air conditioning industry, the demand for miniaturized outdoor air conditioning units is becoming increasingly urgent. For example... Figure 1 As shown, the traditional air conditioner outdoor unit control board 110 adopts a single board design, which integrates filter components, rectifier bridge, PFC inductor, DC bus capacitor, power supply circuit, as well as larger key individual components such as PFC power switch, PFC diode, compressor IPM (Intelligent Power Module) and fan IPM onto the same control board.

[0003] This layout presents numerous problems. First, it results in a bulky control board that occupies a significant portion of the outdoor unit, severely limiting the design flexibility and making adjustments difficult. Furthermore, the compact arrangement of so many power components hinders heat dissipation, severely restricting cooling efficiency and failing to align with the current trend towards more compact and miniaturized outdoor air conditioning units.

[0004] In addition, the current installation structure also has defects. Due to design reasons, the traditional air conditioner outdoor unit control board 110 needs to be connected to the circuit through the external terminal block 120. The radiator also needs to be equipped with long refrigerant heat dissipation pipes. These additional components and complex designs undoubtedly increase the overall cost and hinder the further optimization and upgrading of the air conditioner outdoor unit. Utility Model Content

This utilizes the low-temperature working environment of the liquid storage tank to improve the heat dissipation rate. This not only solves the problem of increased heat dissipation costs caused by increasing the power of the fan and the volume of the radiator, but also avoids the problem of the circuit modules on the second circuit board failing to work properly when the compressor vibrates, thus improving the stability of the system.

[0049] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. The present utility model can be presented in various forms, and some examples will be described below.

[0050] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0051] Furthermore, if the embodiments of this utility model involve descriptions such as "first," "second," etc., these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Moreover, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on what a person skilled in the art can implement. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0052] This utility model proposes an electronic control component that can be used in equipment such as air conditioners and refrigerators. For ease of understanding, the following examples will be based on its application in air conditioners.

[0053] Reference Figure 2 The electronic control component 200 in this embodiment includes an AC power input terminal 261, a filter circuit 204, a rectifier bridge 201, a PFC circuit 240, a power supply circuit 212, a main controller 222, a DC bus capacitor 203, a compressor IPM module 231, and a fan IPM module 232. The AC power input terminal 261 is used to receive AC input voltage. The input terminal of the filter circuit 204 is connected to the AC power input terminal 261. The input terminal of the rectifier bridge 201 is connected to the output terminal of the filter circuit 204. The output terminal of the rectifier bridge 201 is connected to the input terminal of the PFC circuit 240. The output terminal of the PFC circuit 240 is connected to the input terminals of the compressor IPM module 231 and the fan IPM module 232. The DC bus capacitor 203 is connected in parallel to the output terminal of the PFC circuit 240. The main controller 222 is connected to the PFC circuit 240, the compressor IPM module 231, and the fan IPM module 232 respectively. The input terminal of the power supply circuit 212 is connected to the output terminal of the filter circuit 204. The power supply circuit 212 is used to convert the AC input voltage into various values ​​of driving voltage, such as generating 5V, 15V, etc., to power the main controller 222 and other components.

[0054] Furthermore, referring to Figure 5 and Figure 8 The PFC circuit 240 may include components such as a PFC inductor 241, a PFC diode 242, and a PFC power switch 243 to achieve power factor correction of the DC power supply. The PFC circuit 240 can be implemented using a passive PFC circuit to form a boost PFC circuit, a buck PFC circuit, or a buck-boost PFC circuit. It is understood that in practical applications, the position and connection relationship between the PFC power switch 243 and the rectifier bridge 201 can be adaptively adjusted according to the PFC circuit 240's configuration type. The PFC circuit 240 is controlled by a main controller (e.g., an MCU) 222 and adjusts the power factor of the DC voltage input to the rectifier bridge 201, for example, by increasing and stabilizing the DC voltage output from the rectifier bridge 201 to 380V, so that the input current follows the input voltage, ensuring that the power factor of the DC power supply is above 0.9. The adjusted DC power is transmitted to the DC bus capacitor 203, and after being filtered by the DC bus capacitor 203, it is output to the compressor IPM module 231 and the fan IPM module 232 to supply power to the compressor IPM module 231 and the fan IPM module 232.

[0055] Furthermore, referring to Figure 3The electronic control assembly 200 includes a first circuit board 210 and a second circuit board 220. The first circuit board 210 has various passive devices 211 with a large area, the power supply circuit 212, and terminals 213. The second circuit board 220 has various power devices 221 that generate heat during operation and a main controller 222. The first circuit board 210 and the second circuit board 220 are connected by a connecting line 230. For example, the connecting line 230 may include a PFC positive line (PFC+), a DC bus positive line (VDC), a 15V power supply line (VCC), a ground line (GND), and communication / control signal lines. Furthermore, the first circuit board 210 is also connected to the live wire (L1), neutral wire (N1), ground wire (PE1), and the communication signal line (SI1) with the indoor unit to receive AC input power and / or various communication and control signals.

[0056] Furthermore, referring to Figure 4 In another embodiment, the first circuit board 210 is provided with various passive devices 211 and terminals 213 with a large area, and the second circuit board 220 is provided with various power devices 221, a main controller 222 and the power supply circuit 212. This utility model does not limit this.

[0057] Furthermore, referring to Figure 5 and Figure 6 In the first embodiment, passive components such as the rectifier bridge 201, the DC bus capacitor 203, the filter circuit 204, and the PFC inductor 241 are mounted on the first circuit board 210. Since these components have a large area and are all through-hole devices, the PCB board of the first circuit board 210 in this embodiment can be a single-sided board, which helps reduce the cost of the PCB board. Furthermore, the first circuit board 210 is also provided with an AC power input terminal 261, a DC power output terminal 262, and a communication terminal 213. The AC power input terminal 261 is used to connect to the input power line 217 to receive AC input voltage and communication signals with the indoor unit. The DC power output terminal 262 is used to connect to the second circuit board 220 to provide DC voltage. The communication terminal 213 is used to realize communication and control signal transmission between the first circuit board 210 and the second circuit board 220. In a further embodiment, a simple control chip can also be mounted on the first circuit board 210. This control chip can communicate with the main controller 222 on the second circuit board 220 through the communication terminal 213.

[0058] Furthermore, in traditional electronic control components, an additional wiring converter is required to connect the input power line to the electronic control board. However, in the electronic control component 200 of this embodiment, since the area of ​​the first circuit board 210 is significantly smaller than that of a traditional electronic control board, the first circuit board 210 can be placed on the support base 250, and the power line 217 can be directly connected to the AC power input terminal 261 of the first circuit board 210. Therefore, the electronic control component 200 of this embodiment can save a wiring converter compared to the existing solution, reducing the material cost and installation process of the air conditioner outdoor unit.

[0059] In this embodiment, the power supply circuit 212 can be composed of components such as a transformer, a DC voltage regulator chip, a switching power supply chip, a voltage sampling resistor, and a current sampling resistor. The power supply circuit 212 converts the input AC or DC power supply to generate various driving voltages, such as 3.3V, 5V, 12V, and 15V, to power the components on the second circuit board 220, such as the main controller 10, and the first circuit board 210. In this embodiment, the filter circuit 204 can provide EMC, EMS, and lightning protection functions for both the first circuit board 210 and the second circuit board 220.

[0060] It should be noted that, referring to Figure 7 In another embodiment, the rectifier bridge 201, power supply circuit 212 and PFC inductor 241 can be set on the second circuit board 220, and the first circuit board 210 can only be provided with DC bus capacitor 203, filter circuit 204, communication terminal 213, AC power input terminal 261 and DC power output terminal 262. This utility model does not limit this.

[0061] In this embodiment, the number of DC bus capacitors 203 can be one or more, depending on the horsepower of the power device. For example, in a 1-horsepower or 2-horsepower air conditioner, the number of DC bus capacitors 203 is generally set to one, while in a 3-horsepower or higher air conditioner, the number of DC bus capacitors 203 is generally set to two or more. Of course, in other embodiments, the number of DC bus capacitors 203 can be set according to the energy storage requirements of the power device, and there is no limitation here.

[0062] Furthermore, referring to Figures 8 to 13In this embodiment, the second circuit board 220 has a first surface 205 and a second surface 206 facing away from each other. The main controller 222 and the terminal block 223 are disposed on the first surface 205, and the plurality of power devices 221 are disposed on the second surface 206. It should be noted that in another embodiment, the second circuit board 220 may also be a single-sided board, with the plurality of power devices 221 and the main controller 222 disposed on the same surface of the second circuit board 220; this invention does not impose limitations on this.

[0063] Furthermore, the plurality of power devices 221 may include the compressor IPM module 231, the fan IPM module 232, the PFC diode 242, and the PFC power switch 243, etc.

[0064] Furthermore, the wiring terminals 223 provided on the first surface 205 of the second circuit board 220 may include a fan wiring terminal 251, a DC power input terminal 252, a compressor wiring terminal 253, and a communication terminal 254. Specifically, the fan wiring terminal 251 is used to connect to the three-phase motor harness of the outdoor unit's fan; the DC power input terminal 252 is used to connect to the DC power output terminal 262 on the first circuit board 210; the compressor wiring terminal 253 is used to connect to the three-phase motor harness of the compressor; and the communication terminal 254 is used to connect to the communication terminal 213 on the first circuit board 210. Furthermore, the main controller 222 integrates a timing controller, a memory, a data processor, and software programs and / or modules stored in the memory and executable on the data processor. The main controller 222 runs or executes the software programs and / or modules stored in the memory, and calls data stored in the memory. It also communicates with the first circuit board 210 and the control unit on the indoor unit through the communication interface 254 to receive control signals output from the control unit. The main controller 222 converts the control signals into corresponding logic level signals and outputs them to the PFC power switch 243, the compressor IPM module 231, and the fan IPM module 232 to drive the PFC power switch 243, the compressor IPM module 231, and the fan IPM module 232 to work.

[0065] It is understood that the first surface 205 of the second circuit board 220 may also be provided with a real-time detection circuit that can detect parameters such as current, temperature and voltage of each component in the rectifier bridge 201, PFC power switch 243, compressor IPM module 231 and fan IPM module 232. In the event of severe overload or even short circuit, or overheating, drive voltage overvoltage or other faults, it can control the power devices in the IPM module to softly shut down and send a fault signal to the control circuit unit so that the control circuit unit can control other circuit modules to work, thereby avoiding damage to other circuit modules due to faults.

[0066] In this embodiment, the compressor IPM module 231 integrates multiple power switching transistors, which together form a drive inverter circuit. For example, a three-phase inverter bridge circuit can be composed of six power switching transistors, or a two-phase inverter bridge circuit can be composed of four power switching transistors. Each power switching transistor can be implemented using a MOSFET or an IGBT. The compressor IPM module 231 is used to drive the compressor motor. In other embodiments, the compressor IPM module 231 can also be used to drive inverters for other motors and various inverter power supplies, and can be applied in variable frequency speed control, metallurgical machinery, electric traction, servo drives, and variable frequency home appliances such as air conditioners. It is understood that, to improve the integration of the compressor IPM module 231 and reduce the size of the circuit board, this embodiment can encapsulate the PFC diode 242 and / or the PFC power switch 243 within the compressor IPM module 231. In other embodiments, the PFC diode 242, the PFC power switch 243, and the compressor IPM module 231 can also be separately configured; this is not a limitation.

[0067] It should be noted that the outdoor fan of an air conditioner can be divided into AC fans and DC fans. AC fans generally do not require a driver to operate, while DC fans require a power drive to control their operation. In this embodiment, a DC fan can be selected as the outdoor fan. Accordingly, this embodiment also includes a DC fan IPM module 232 for driving the DC fan. The DC fan IPM module 232 and the compressor IPM module 231 each integrate multiple IGBTs, MOSFETs, and other power switching transistors. The number of power switching transistors can be four or six, and the specific number can be set according to the motor type, drive power, etc., and is not limited here. Furthermore, to reduce the size of the circuit board, in this embodiment, the PFC diode 242 and / or the PFC power switch 243 can be packaged in the fan IPM module 232, or the PFC diode 242 and the PFC power switch 243 can be packaged together, and the compressor IPM module 231 and the fan IPM module 232 can be packaged together, or the PFC diode 242, the PFC power switch 243, the compressor IPM module 231, and the fan IPM module 232 can be packaged together. Of course, in other embodiments, the PFC diode 242, the PFC power switch 243, the compressor IPM module 231, and the fan IPM module 232 can also be disposed separately, and there is no limitation here.

[0068] It should be noted that the compressor IPM module 231, fan IPM module 232, and PFC power switch 243 generally generate significant heat during operation. The heat generated by the power devices is conducted to the main controller 222 through the circuit board, causing the temperature of the main controller 222 to rise. Since the ideal operating temperature of the main controller 222 is mostly lower than that of the power devices, the operating temperature of the power devices may cause the main controller 222 to overheat and malfunction, making it prone to outputting incorrect control signals.

[0069] Reference Figure 13 To avoid the aforementioned problems, the electronic control component 200 in this embodiment further includes a heat sink 270, which is connected to the second surface 206 of the second circuit board 220, thereby dissipating heat from the power devices on the second circuit board 220 and reducing the temperature of the second circuit board 220. Further, the heat sink 270 can be mounted on the second surface of the second circuit board 220 by one or more combinations of screws, bolts, riveting, welding, snap-fitting, and plugging. In a further embodiment, the heat sink 270 can also be disposed on the first circuit board 210 to dissipate heat from the devices on the first circuit board 210. Further, the heat dissipation method of the heat sink 270 includes air cooling or refrigerant cooling.

[0070] In a further embodiment, the present invention also proposes an outdoor unit, which may include a compressor and the electronic control component 200 as described above. The detailed structure of the electronic control component 200 can be referred to the above embodiments and will not be repeated here.

[0071] In a further embodiment, the present invention also proposes an air conditioner, which may include a compressor and the electronic control component 200 as described above. Alternatively, the air conditioner may include an indoor unit and an outdoor unit as described above, wherein the main controller of the outdoor unit is communicatively connected to the main control chip of the indoor unit, and the structure of the electronic control component 200 or the outdoor unit is the same as described in the above embodiments, and will not be repeated here.

[0072] It should be understood that the air conditioner can be a split-type air conditioner or an integrated air conditioner. Since the embodiments of the air conditioner include all embodiments of the above-mentioned electronic control components or outdoor units, and have the same technical effects as the above-mentioned electronic control components or outdoor units, they will not be described again here.

[0073] In summary, the electrical control component of this utility model is implemented using two circuit boards, a first circuit board and a second circuit board. Various passive components are placed on the first circuit board, and various power devices are placed on the second circuit board. This not only reduces the area of ​​a single circuit board and facilitates its installation in the housing of the electrical control component, but also simplifies the PCB layout of the electrical control board and improves design flexibility.

[0074] In addition, the electronic control component of this utility model can also solve the problems of dense components, difficult circuit wiring and electrical isolation that exist when using a whole circuit board.

[0075] Furthermore, the electronic control component of this invention can also separate the heat source device and the non-heat source device, which can prevent the heat source device from dissipating heat to the non-heat source device and affecting the operation of the non-heat source device.
