In addition, due to the large number of loads on the display board, more connecting wires are required during production and installation, which is extremely inconvenient for the production and installation of the display board.

[0059] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0060] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0061] With technological advancements driving the rapid development of smart homes, high-end air conditioning electronic control technology is constantly evolving, emphasizing user experience and focusing on user interactions during use to achieve technological leadership, direct user engagement, and quality breakthroughs. Among these advancements, the multi-functional integration of high-end air conditioners is receiving increasing attention, such as diversified display and interaction methods including touch button interaction, voice interaction, radar-based automatic anti-cold airflow, air quality display, and automatic fresh air function. As peripheral loads increase, the load on the electronic control system becomes heavier, increasing the demand for MCU resources, including display drivers, multiple stepper motor drivers, multiple sensors, and voice modules. A more complex power supply architecture also translates to higher costs. Therefore, improving the complex low-voltage power supply system of the electronic control system and preventing mutual interference between peripheral load functions is an important research direction.

[0062] Currently, the main control board and display board of the indoor unit of the air conditioner are separate. The display board bears most of the peripheral load. Since the display and the load are located on the same circuit board, the frequent start and stop of the motor in the load will interfere with the electrical plane stability of the display board, resulting in excessive power ripple and display flickering under heavy load. In addition, due to the large number of loads on the display board, more connecting wires are required during production and installation, which is extremely inconvenient for the production and installation of the display board.

[0063] This utility model proposes an electronic control component 1, which aims to improve the stability of the display of the electronic control component 1, and at the same time, facilitate its production and installation.

[0064] Reference Figure 1 In one embodiment of this utility model, the electronic control component 1 is applied to a refrigeration device 100, which includes a main control board 2, a display component 3, and a load 4. The electronic control component 1 includes a display board 11 and a driver board 12. The display board 11 is electrically connected to both the main control board 2 and the display component 3, and is used to receive control signals output by the main control board 2 and control the display component 3 to operate. The driver board 12 is electrically connected to both the main control board 2 and the load 4, and is used to receive control signals output by the main control board 2 and drive the load 4 to operate.

[0065] It is understandable that the main control board 2 can be the main board of the indoor unit of the air conditioner or the main board of the air conditioner. The main control board 2 integrates various electronic components and can be equipped with a processor, memory, etc. The processor controls the display board 11 and the driver board 12 through the control program stored in the memory.

[0066] Display panel 11 can be the display panel of the indoor unit of the air conditioner, or it can be the display panel of the air conditioner itself. (See reference...) Figure 4 The display panel 11 may include a display circuit board 111, which integrates various electronic components. The display circuit board 111 may also include a first power processing circuit 112 and a display driving circuit 113. The power input terminal of the first power processing circuit 112 can be connected to the power output terminal of the main control board 2, allowing the main control board 2 to supply power to the display panel 11. Alternatively, it can be connected to the power supply of an air conditioner, directly powering the display panel 11. Therefore, there are many ways to power the display panel 11, and no specific method is limited here. The controlled terminal of the display driving circuit 113 is connected to the control terminal of the main control board 2, and the driving terminal of the display driving circuit 113 is connected to the display component 3. The display driving circuit 113 is used to drive the display component 3 to display when it receives a display control signal output from the main control board 2. The display component 3 can be the display screen of an indoor air conditioner or the display screen of the air conditioner itself. The display screen can show the air conditioner's operating status, including whether it is on or off, fan speed, and temperature, based on the received display control signals. This allows users to easily understand the air conditioner's working status in real time. It can also display the air conditioner's operating mode, such as cooling, heating, dehumidifying, and ventilation, based on the received display control signals.

[0067] The drive board 12 can be an adapter board for an air conditioner, or it can be a drive board 12 specifically designed to drive components such as fans. (See reference...) Figure 5The driver board 12 may include a driver circuit board 121, which integrates various electronic components. The driver circuit board 121 may also include a second power processing circuit 123 and a load driving circuit 122. The power input terminal of the second power processing circuit 123 can be connected to the power output terminal of the main control board 2, supplying power to the driver board 12 via the main control board 2; alternatively, it can be connected to the power output terminal of the display board 11, supplying power to the driver board 12 via the display board 11; or it can be connected to the power supply of an air conditioner, directly supplying power to the driver board 12. Therefore, there are many ways to supply power to the driver board 12, and no specific method is limited here. The controlled terminal of the load driving circuit 122 is connected to the control terminal of the main control board 2, and the driving terminal of the load driving circuit 122 is connected to the load 4.

[0068] It should be noted that load 4 specifically refers to the air guiding mechanism of the indoor unit of the air conditioner. The air guiding mechanism may include a housing, an air outlet frame, an air guide plate, and a motor. The housing forms an air duct and an air outlet communicating with the air duct. The air outlet frame is installed in the air duct of the housing and located at the air outlet. The air guide plate is connected to the air outlet frame, and the air outlet frame is connected to the housing through the motor. The drive end of the load drive circuit 122 is connected to the motor. When the load drive circuit 122 receives the drive control signal output by the main control board 2, it drives the motor to rotate so as to move the air guide plate at the air outlet. The movement of the air guide plate at the air outlet is not limited to up-and-down swinging, left-and-right swinging, and left-and-right door opening and closing. Correspondingly, the motor may include, but is not limited to, an up-and-down swinging motor, a down-and-right swinging motor, a left-and-right swinging motor, a left-opening motor, a left-closing motor, a right-opening motor, and a right-opening motor. For example, when the load drive circuit 122 receives the upward swing fan drive control signal output by the main control board 2, the load drive circuit 122 drives the upward swing fan motor to rotate, thereby causing the air guide plate to swing upward at the air outlet to adjust the air outlet direction of the air conditioner. It can be seen that other movements of the air guide plate are similar, and will not be described in detail here.

[0069] The technical solution of this utility model involves setting up an electronic control component 1, which is applied to a refrigeration device 100. The refrigeration device 100 includes a main control board 2, a display component 3, and a load 4. The electronic control component 1 includes a display board 11 and a driver board 12. The display board 11 is electrically connected to both the main control board 2 and the display component 3. The display board 11 receives control signals output from the main control board 2 and controls the operation of the display component 3. The driver board 12 is electrically connected to both the main control board 2 and the load 4. The driver board 12 receives control signals output from the main control board 2 and drives the load 4. By setting up separate display boards 11 and 12, the display board 11 is electrically connected to the display component 3, and the driver board 12 is electrically connected to the load 4. That is, the display component 3 and the load 4 are placed on different circuit boards. This can avoid the frequent start and stop of the motor in the load 4 from interfering with the electrical plane stability of the display board 11, overcome the technical defects of excessive power ripple and display flicker when the load 4 is under heavy load, reduce the number of flickering times of the display component 3, and improve its display stability. Furthermore, since the load 4 is no longer located on the display board 11, the number of components arranged on the display board 11 is reduced, and no more connecting wires are needed during production and installation, which is beneficial for the production and installation of the display board 11.

[0070] Reference Figure 2 In one embodiment of this utility model, the driver board 12 is electrically connected to the main control board 2 via the display board 11. And / or, the driver board 12 is electrically connected to the main control board 2 via a connector 13. The driver board 12 can draw power from the display board 11 and communicate with the main control board 2 via the display board 11. This allows for the installation of the driver board 12 without adding excessive connecting lines to the main control board 2, which is beneficial for the production and installation of the main control board 2. Alternatively, the driver board 12 can draw power from the display board 11, while communication is directly provided by the main control board 2, thus improving the communication capability of the driver board 12. Alternatively, the driver board 12 can communicate with the main control board via the display board 11, while the power supply to the driver board 12 is directly provided by the main control board 2. This reduces the disturbance of the load 4 connected to the driver board 12 on the display board 11 and its connected display components 3 during power supply, improving the electrical plane stability of the display board 11 and thus enhancing its display performance. Of course, in other embodiments, the driver board 12 may simply be connected to the main control board via a connector on the display board 11. That is, there is only a physical connection between the driver board 12 and the display board 11, while the driver board 12 and the main control board are directly electrically connected via the connector on the display board 11. In this way, the disturbance of the load 4 connected to the driver board 12 on the display board 11 and its connected display components 3 can be reduced, thereby improving the display performance of the display components 3.

[0071] Reference Figure 4 In one embodiment of this utility model, the display panel 11 includes:

[0072] Display circuit board 111;

[0073] A first power processing circuit 112 is disposed on the display circuit board 111. The power input terminal of the first power processing circuit 112 is used to connect to a power supply. The first power processing circuit 112 is used to process the power supply connected to the power supply.

[0074] The display driving circuit 113 is disposed on the display circuit board 111. The power input terminal of the display driving circuit 113 is connected to the power output terminal of the first power processing circuit 112. The first power output terminal of the display driving circuit 113 is connected to the display component 3 and is used to supply power to the display component 3.

[0075] It is understood that there are many power supply methods for the display panel 11. In this embodiment, the display panel 11 includes a display circuit board 111. Various electronic components are integrated on the display circuit board 111, which may include a first power processing circuit 112 and a display driving circuit 113. The first power processing circuit 112 may include a first DC-DC conversion circuit and a first voltage regulator circuit. The power input terminal of the first DC-DC conversion circuit is used to connect to a power supply, wherein the power supply is a DC power supply located on the main control board 2. It mainly receives the DC voltage signal output from the DC power supply of the main control board 2 and converts the received DC voltage signal into the DC voltage signal required by the display driving circuit 113 before outputting it to the display driving circuit 113. The first DC-DC conversion circuit may include at least one of a buck converter, a boost converter, or a buck-boost converter; no specific limitation is made here. The first voltage regulator circuit mainly maintains the stability of the output voltage through an internal first regulating transistor. Specifically, when the input DC voltage signal changes, the first regulating transistor adjusts the DC voltage signal output to the display driving circuit 113 by changing its own impedance, thereby maintaining the stability of the output voltage. The display driver circuit 113 may include a display driver chip and a display amplifier circuit. After receiving the control signal output by the main control board 2, the display driver chip generates a corresponding display driver signal. The display amplifier circuit amplifies the display driver signal generated by the display driver chip so that it can drive the display component 3 to work. To power the display driver circuit 113 and the display component 3, the power input terminal of the display driver circuit 113 is connected to the power output terminal of the first power processing circuit 112, and the first power output terminal of the display driver circuit 113 is connected to the display component 3. In this way, the display component 3 is powered through the display board 11, instead of being directly powered from the main control board 2, which simplifies the wiring connection of the main control board 2 and improves the convenience of production and installation of the main control board 2.

Various electronic components are integrated on the driver circuit board 121, and a load drive circuit 122 may be provided on the driver circuit board 121. The load drive circuit 122 is specifically a motor drive circuit, which may include a load drive chip and a power amplifier, etc. After receiving the control signal output by the main control board 2, the load drive chip generates a corresponding drive signal. This drive signal determines the speed and direction of the motor. The power amplifier amplifies the drive signal generated by the load drive chip to meet the high power requirements of the motor. To realize the power supply of the load drive circuit 122 and the load 4, the power input terminal of the load drive circuit 122 is connected to the second power output terminal of the display drive circuit 113, and the power output terminal of the load drive circuit 122 is connected to the load 4. In this way, the main control board 2 provides a stable power supply to the load 4 through the display board 11 and the driver board 12 in sequence. This reduces the power lines between the load 4 and the main control board 2, simplifies the structure of the main control board 2, and improves the convenience of production and installation of the main control board 2.

[0089] It is understood that there are many communication methods for the display board 11. In this embodiment, the display board 11 includes a display circuit board 111. Various electronic components are integrated on the display circuit board 111, which may include a first communication circuit 114 and a display driver circuit 113. The first communication circuit 114 is implemented using a first communication interface, which is a first serial port capable of converting between parallel and serial data reception and transmission. The signal input terminal of the first serial port is used to receive control signals output by the main control board 2 and output them to the display driver circuit 113. The display driver circuit 113 may include a display driver chip and a display amplifier circuit. The signal input terminal of the display driver chip is connected to the signal output terminal of the first serial port, the first signal output terminal of the display driver chip is connected to the signal input terminal of the display amplifier circuit, and the signal output terminal of the display amplifier circuit is connected to the display component 3. After receiving the control signals output by the main control board 2 via the first serial port, the display driver chip generates corresponding display driver signals. The display amplifier circuit amplifies the display driver signals generated by the display driver chip, enabling them to drive the display component 3 to operate.

[0090] To meet different display functions, refer to Figure 6 In another embodiment of this utility model, the display component 3 includes an LED display module and a color filter backlight display module. The LED display module does not require high brightness; to achieve segmented display, the display driver chip is an AIP3331 chip. The AIP3331 chip is a dot-matrix constant current LED load driver chip, configured via an IIC communication interface, and can drive a dot matrix composed of up to 144 monochrome LEDs. The color filter backlight display module requires higher brightness; the display driver chip is electrically connected to a PWM port, which drives multiple color filter areas. The backlight brightness is adjusted by changing the duty cycle of the frequency, with up to 16 adjustment levels.

[0091] Reference Figure 6 In one embodiment of this utility model, the drive board 12 includes:

[0092] Driver circuit board 121;

[0093] A load driving circuit 122 is disposed on the driving circuit board 121. The signal input terminal of the load driving circuit 122 is connected to the second signal output terminal of the display driving circuit 113, and the signal output terminal of the load driving circuit 122 is connected to the load 4. The load driving circuit 122 is used to receive the control signal output by the main control board 2 through the first communication circuit 114 and the display driving circuit 113, and drive the load 4 to work according to the control signal.

[0094] It is understood that the communication methods of the driver board 12 can vary. In this embodiment, the driver board 12 includes a driver circuit board 121. Various electronic components are integrated on the driver circuit board 121, and a load drive circuit 122 may be provided on the driver circuit board 121. The load drive circuit 122 is specifically a motor drive circuit, which may include a load drive chip and a power amplifier, etc. The signal input terminal of the load drive chip is connected to the second signal output terminal of the display driver chip, the signal output terminal of the load drive chip is connected to the signal input terminal of the power amplifier, and the signal output terminal of the power amplifier is connected to the load 4. The display driver chip receives the control signal output by the main control board 2 via the first serial port and forwards it to the load drive chip. The load drive chip generates a corresponding load drive signal based on the received control signal. The power amplifier amplifies the load drive signal generated by the load drive chip, enabling it to drive the load 4 to work. It can be seen that the drive board 12 communicates with the main control board 2 through the display board 11. That is, the drive board 12, the display board 11 and the main control board 2 communicate with each other. Only one communication line can be led out between the main control board 2, the display board 11 and the drive board 12, which can facilitate the production of the air conditioner indoor unit and greatly improve the quality and efficiency of production.

[0095] Reference Figure 7 In one embodiment of this utility model, the drive board 12 includes:

[0096] Driver circuit board 121;

[0097] The second communication circuit 124 is disposed on the drive circuit board 121. The signal input terminal of the second communication circuit 124 is used to receive control signals. The second communication circuit 124 is used to communicate with the main control board 2.

[0098] A load drive circuit 122 is disposed on the drive circuit board 121. The signal input terminal of the load drive circuit 122 is connected to the signal output terminal of the second communication circuit 124, and the signal output terminal of the load drive circuit 122 is connected to the load 4. The load drive circuit 122 is used to receive the control signal output by the main control board 2 through the second communication circuit 124, and drive the load 4 to work according to the control signal.

[0099] It is understood that, unlike the above embodiments, in this embodiment, the driver board 12 includes a driver circuit board 121. Various electronic components are integrated on the driver circuit board 121, which may include a second communication circuit 124 and a load drive circuit 122. The second communication circuit 124 is implemented using a second communication interface, which is a second serial port capable of converting between parallel and serial data reception and transmission. The signal input terminal of the second serial port is used to receive control signals output by the main control board 2 and output them to the load drive circuit 122. The load drive circuit 122 is specifically a motor drive circuit, which may include a load drive chip and a power amplifier. The signal input terminal of the load drive chip is connected to the signal output terminal of the second serial port, the signal output terminal of the load drive chip is connected to the signal input terminal of the power amplifier, and the signal output terminal of the power amplifier is connected to the load 4. After receiving the control signals output by the main control board 2 via the second serial port, the load drive chip generates corresponding load drive signals. The power amplifier amplifies the load drive signals generated by the load drive chip, enabling it to drive the load 4 to operate. That is, in this embodiment, the driver board 12 and the display board 11 communicate independently, which can reduce signal interference between the two boards and improve the stability of communication between the driver board 12 and the main control board 2, as well as between the display board 11 and the main control board 2.

[0100] Reference Figure 8 In one embodiment of this utility model, the drive board 12 includes:

[0101] A driving circuit board 121 having a first edge 1211;

[0102] The load drive circuit 122 is disposed on the drive circuit board 121 and is disposed near the first edge 1211.

[0103] Understandably, compared to existing air conditioner indoor units, this solution includes not only the main control board 2 and the display board 11, but also a drive board 12. To avoid excessively increasing the size of the air conditioner indoor unit and to make its structure more compact, the drive board 12 is located on the air outlet frame of the air guide mechanism of the air conditioner indoor unit.

[0104] In this embodiment, the drive board 12 includes a drive circuit board 121 and a load drive circuit 122. The drive circuit board 121 has a first edge 1211. The load drive circuit 122 is disposed on the drive circuit board 121 and close to the first edge 1211. With this design, the power line, communication line and wire of the load drive circuit 122 can be directly led out into the air outlet frame without crossing other circuits on the drive board 12, which facilitates wiring, reduces electromagnetic interference caused by complex wiring, and improves the anti-interference performance of the air conditioner indoor unit.

[0105] Reference Figure 9In one embodiment of this utility model, the display panel 11 includes:

[0106] Display circuit board 111, the display circuit board 111 having a first side surface 1111 and a second side surface 1112 disposed opposite to each other;

[0107] The display driving circuit 113 is disposed on the first side surface 1111, and the display component 3 is disposed on the second side surface 1112.

[0108] Based on the above embodiments, in this embodiment, the display panel 11 is disposed on the display component 3 of the indoor unit of the air conditioner. Specifically, the display panel 11 includes a display circuit board 111 and a display driving circuit 113. The display circuit board 111 has a first side surface 1111 and a second side surface 1112 disposed opposite to each other along the thickness direction. The display driving circuit 113 is disposed on the first side surface 1111 of the display circuit board 111, and the display component 3 is disposed on the second side surface 1112 of the display circuit board 111. This allows the volume of the display portion to be compressed in the thickness direction of the display circuit board 111, making the structure of the indoor unit of the air conditioner more compact.

[0109] To improve the ease of use of air conditioners, refer to Figure 9 In one embodiment of the present invention, the electronic control component 1 further includes a touch circuit 14, which is disposed on the display circuit board 111 and is electrically connected to the display driving circuit 113.

[0110] In this embodiment, the touch circuit 14 is mainly composed of capacitive touch buttons. Each capacitive touch button consists of a conductive layer and an insulating layer. When a user touches the capacitive touch button, the human body and the conductive layer form a capacitor, causing a change in the charge at the touch point. The capacitive touch button can be mounted on the display circuit board 111 and electrically connected to the display driving circuit 113, allowing the display driving circuit 113 to collect these charge changes and forward them to the main control board 2 in the form of electrical signals. The main control board 2 determines the touch position based on the received electrical signals and then determines which function of the air conditioner the user has triggered. Furthermore, mounting the capacitive touch button on the display circuit board 111 prevents it from being mounted on the same circuit board as the load 4, reducing the impact of frequent motor starts and stops in the load 4 on the touch function of the capacitive touch button, preventing touch recognition failures, improving the reliability of the touch signal, and enhancing the production and quality efficiency of the air conditioner indoor unit and even the entire air conditioner.

[0111] Reference Figure 9In one embodiment of this utility model, the touch circuit 14 is disposed on the first side surface 1111 and close to the display driving circuit 113. In this way, the connection between the touch circuit 14 and the display driving circuit 113 is shortened, simplifying the connection between the two and improving the signal-to-noise ratio and anti-interference performance of the air conditioner indoor unit.

[0112] Reference Figure 9 In one embodiment of the present invention, the display circuit board 111 has a second edge 1113, and the touch circuit 14 is disposed close to the second edge 1113. In this way, the leads of the touch circuit 14 can be led out from the edge of the display circuit board 111, avoiding them from crossing other modules or devices on the display circuit board 111, which facilitates wiring and improves the anti-interference problem caused by complex wiring.

[0113] Reference Figure 8 and Figure 9 In one embodiment of this utility model, the electronic control component 1 further includes multiple functional module control circuits. These multiple functional module control circuits may include a photosensitive module control circuit 15, an infrared receiving module control circuit 16, a positioning module control circuit 17, an alert module control circuit 18, a voice recognition module control circuit 19, a wireless communication module control circuit 20, an audio module control circuit 21, etc.

[0114] The photosensitive module control circuit 15 is disposed on the second side surface 1112 of the display circuit board 111. The photosensitive module control circuit 15 is used to connect the photosensitive module, which is used to detect the ambient light intensity. The display driving circuit 113 is also used to adjust the display brightness of the display component 3 according to the light intensity detected by the photosensitive module, so as to achieve the purpose of making the user's eyes comfortable. Furthermore, since the photosensitive signal has high requirements for power supply stability, the power supply ripple is required to be within 140mV. Since the display circuit board 111 and the driving circuit board 121 are disposed separately, the power supply ripple of the display circuit board 111 can be within 140mV. Therefore, by placing the photosensitive module control circuit 15 on the display circuit board 111, the interference of the load 4 on it can be reduced.

[0115] The infrared receiving module control circuit 16 is disposed on the second side surface 1112 of the display circuit board 111. The infrared receiving module control circuit 16 is used to connect the infrared receiving module, which is used to receive infrared signals. The display driving circuit 113 is also used to generate a feedback signal based on the infrared signal received by the infrared receiving module and output it to the main control board 2. The main control board 2 controls the air conditioner to turn on or off based on the feedback signal. Infrared signals also have high requirements for power supply stability, and the power supply ripple is required to be within 140mV. The display circuit board 111 and the driving circuit board 121 are disposed separately, and the power supply ripple of the display circuit board 111 can be within 140mV. Therefore, by placing the infrared receiving module control circuit 16 on the display circuit board 111, the interference of the load 4 on it can also be reduced.

[0116] The positioning module control circuit 17 is located on the first surface 1111 of the display circuit board 111. Specifically, the positioning module control circuit 17 is a radar serial port used to connect to a radar sensor. The radar sensor can detect the user's presence, location, and movement status, and send this data to the display driver circuit 113 via the radar serial port. The display driver circuit 113 then forwards this data to the main control board 2. Based on the received data, the main control board 2 adjusts the air conditioner's operating mode, for example, automatically adjusting the air outlet direction to achieve the functions of "air blowing towards the person" and "air avoiding the person," thereby improving the comfort and energy efficiency of the air conditioner.

[0117] The reminder module control circuit 18 is used to connect the reminder module, which is specifically a buzzer. The buzzer mainly emits a buzzing sound to alert the user when the air conditioner malfunctions, or even when the air conditioner itself malfunctions. The reminder module control circuit 18 can be located on the display circuit board 111 or the driver circuit board 121, depending on the sealing performance of the display board 11 and the driver board 12. For example, if the driver board 12 has a stronger sealing performance than the display board 11, the buzzer can be located on the first side surface 1111 of the display circuit board 111, allowing the buzzer sound to be effectively emitted outwards. Furthermore, the buzzer can be modulated using a set of PWM frequencies to change the volume of the buzzer sound, meeting the user's needs for different levels of alert volume.

[0118] The voice recognition module control circuit 19 is disposed on the first side surface 1111 of the display circuit board 111, and is used to connect the voice recognition module. By controlling the air conditioner through the voice recognition module, users can avoid frequent use of the remote control, thus bringing a more convenient lifestyle.

[0119] The wireless communication module control circuit 20 is disposed on the first side surface 1111 of the display circuit board 111, and is used to connect to the wireless communication module. Through the wireless communication module, users can remotely control the air conditioner via smartphones or other smart terminals, improving the convenience and comfort of using the air conditioner.

[0120] The audio module control circuit 21 is disposed on the first side surface 1111 of the display circuit board 111. The audio module control circuit 21 is used to connect the audio module, which may include a speaker, etc., and emits prompt sounds through the speaker. These prompt sounds include sounds when the air conditioner is turned on, the mode is changed, the temperature is adjusted, the fan speed is adjusted, etc., to help users understand the operating status of the air conditioner and improve the user experience.

[0121] In summary, this solution integrates user-interactive functions directly into the display panel 11, including display, touch, photosensitivity detection, infrared reception, positioning, alerts, voice recognition, and wireless communication. This optimizes the space resources of the display panel 11 and facilitates the miniaturization and integrated layout of the electronic control components 1.

[0122] This utility model also proposes a refrigeration device 100, as shown in the reference. Figure 1 and Figure 2 The refrigeration device 100 includes a main control board 2, a display component 3, a load 4, and an electrical control component 1. The specific structure of the electrical control component 1 is as described in the above embodiments. Since this refrigeration device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. Among them, the display board 11 of the electrical control component 1 is electrically connected to the main control board 2 and the display component 3, and the drive board 12 of the electrical control component 1 is electrically connected to the main control board 2 and the load 4.

[0123] It is understandable that the power supply for the refrigeration unit 100 can take many forms, as shown in the reference... Figure 1 In one embodiment of this utility model, the power input terminal of the main control board 2 is used to connect to a power supply, the power input terminal of the display board 11 is connected to the first power output terminal of the main control board 2, the power output terminal of the display board 11 is connected to the display component 3, the power input terminal of the driver board 12 is connected to the second power output terminal of the main control board 2, and the power output terminal of the driver board 12 is connected to the load 4. With this configuration, the display board 11 and the driver board 12 each draw power from the main control board 2, which can reduce the disturbance of the load 4 to the display board 11 and the display component 3, improve the electrical plane stability of the display board 11, and thus improve the display performance of the display component 3.

[0124] Understandably, the communication methods of the refrigeration unit 100 can vary, as shown in the following reference. Figure 2In one embodiment of this utility model, the signal input terminal of the main control board 2 is used to receive control signals, the signal output terminal of the main control board 2 is connected to the signal input terminal of the display board 11, the first signal output terminal of the display board 11 is connected to the display component 3, the second signal output terminal of the display board 11 is connected to the signal input terminal of the drive board 12, and the signal output terminal of the drive board 12 is connected to the load 4. With this configuration, the drive board 12 communicates with the main control board 2 via the display board 11, that is, the drive board 12, the display board 11, and the main control board 2 communicate with each other. Only one communication line needs to be led out between the main control board 2, the display board 11, and the drive board 12, which facilitates the production of the air conditioner indoor unit and greatly improves the quality and efficiency of production.

[0125] This utility model also proposes an indoor air conditioner unit, which includes an air outlet frame, an electrical control box, and a refrigeration device 100. The specific structure of the refrigeration device 100 is as described in the above embodiments. Since this indoor air conditioner unit adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0126] The display panel 11 of the refrigeration unit 100 is located on the display component 3 of the refrigeration unit 100. This display component 3 can also be the indoor unit of an air conditioner, or even the display screen of an air conditioner. The drive board 12 of the refrigeration unit 100 is located on the air outlet frame, so that the load drive circuit 122 on the drive board 12 is located close to the air outlet frame, which facilitates the connection between the load drive circuit 122 and the motor drive on the air outlet frame to achieve drive. The main control board 2 of the refrigeration unit 100 is located in the electrical control box, which can also be the electrical control box of an air conditioner.

[0127] In other words, compared to existing air conditioner indoor units, although this solution adds a drive board 12, it achieves a reasonable layout of the display board 11, drive board 12, and main control board 2 by placing the display board 11 on the original display structure of the air conditioner indoor unit, the drive board 12 on the original drive mechanism of the air conditioner indoor unit, and the main control board 2 on the original control structure of the air conditioner indoor unit. This makes the structure of the air conditioner indoor unit more compact, and even with the addition of the drive board 12, the volume of the air conditioner indoor unit will not be increased excessively.

[0128] This utility model also proposes an air conditioner, which includes an indoor unit. The specific structure of the indoor unit is as described in the above embodiments. Since this air conditioner adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
