[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] It should be noted that this application is made based on the inventor's understanding and research of the following issues:

[0035] The electronic control of the split air conditioner includes an outdoor main control board, an indoor main control board and a display panel. When the outdoor main control board is powered, it is usually divided into two situations, one is the situation without standby power consumption, and the other is the situation with standby power consumption. When there is no standby power consumption, the connection method of the air conditioner electronic control is that the AC power supply is connected to the outdoor side (that is, the outdoor main control board), and the outdoor side is connected to the indoor side (that is, the indoor main control board and the display panel); when there is standby power consumption, because the indoor unit and the outdoor unit are each equipped with a switching power supply, it is difficult for the air conditioner to achieve 1W standby. The connection method of the air conditioner electronic control is that the AC power supply is connected to the outdoor side (the port is powered, and the main board is not powered), the outdoor side is connected to the indoor side (that is, the indoor main control board and the display panel), and the indoor side is connected to the outdoor side. Therefore, whether it is a scenario without standby power consumption or a scenario with standby power consumption, there is an indoor main control board, so the connection relationship of the air conditioner is relatively complex and the cost is relatively high.

[0036] The indoor and outdoor units of conventional split air conditioners are powered by AC mains electricity. Each of the indoor and outdoor units is equipped with an AC-DC power supply (a type of power supply classification, which means that the power supply specification is AC input and DC output) circuit and EMC (Electromagnetic Compatibility) circuit. Because the voltage of these circuits is relatively high, in order to meet safety requirements (anti-electric shock, anti-short circuit ignition), the size of the indoor main control board is relatively large, and it must be equipped with fireproof sheet metal, resulting in a very compact design space inside the indoor unit. Although the size of the indoor main control board can be reduced by using indoor miniaturization technology, because the indoor main control board is equipped with an ignition source part, the indoor main control board cannot be removed, resulting in a complex connection relationship of the air conditioner and a high cost.

[0037] Based on this, an embodiment of the present invention provides an air conditioner and its control method, storage medium, and display panel. The indoor main control is eliminated by integrating the driving part of the fan in the indoor main control board into the indoor fan circuit, and integrating the control part and communication part of the indoor main control board into the display circuit. This not only simplifies the connection relationship of the air conditioner, but also reduces the cost of the air conditioner.

[0038] The air conditioner and its control method, storage medium, and display panel according to embodiments of the present invention are described below with reference to the accompanying drawings.

[0039] Figure 1 FIG. 1 is a schematic diagram of the structure of an air conditioner according to an embodiment of the present invention. Figure 1 As shown, the air conditioner 1000 includes: an indoor unit 100 and an outdoor unit 200 ; the indoor unit 100 includes a display circuit 110 and an indoor fan circuit 120 , and the outdoor unit 200 includes an outdoor unit control circuit 210 .

[0040] Among them, the indoor fan circuit 120 includes a drive control unit 121 and an indoor fan motor 122, the display circuit 110 is connected to the drive control unit 121, and the display circuit 110 is configured to send a first control instruction to the drive control unit 121, so that the drive control unit 121 controls the indoor fan motor 122 according to the first control instruction; the outdoor unit control circuit 210 is suitable for connecting an AC power supply AC and an outdoor unit load, and is communicatively connected with the display circuit 110, and the outdoor unit control circuit 210 is configured to generate DC power according to the AC power supply AC to power the display circuit 110 and the indoor fan circuit 120, and control the outdoor unit load according to the second control instruction sent by the display circuit 110.

[0041] Specifically, the power input terminal of the outdoor unit control circuit 210 is connected to the AC power source AC, and the AC power source AC can be as follows: Figure 1The AC mains shown in FIG. 1 shows a power supply, wherein L is the live wire, N is the neutral wire, and PE is the ground wire. The outdoor unit control circuit 210 generates direct current according to the AC power supply AC, and supplies power to the display circuit 110 and the indoor fan circuit 120. At the same time, the outdoor unit control circuit 210 can also drive the outdoor unit load according to the direct current, such as driving the compressor 221 and the outdoor fan 222. The indoor main control board can be mainly divided into two parts, one part is a weak current control circuit, such as a communication circuit, and the other part is a driving control circuit of the indoor fan. The display circuit 110 is connected to the outdoor unit control circuit 210 for communication. Therefore, in addition to the original display and remote control receiving functions, the display circuit 110 also undertakes the communication with the outdoor control circuit to send a second control instruction to the outdoor unit control circuit 210, and the outdoor unit control circuit 210 controls the outdoor unit load according to the second control instruction. The indoor fan circuit 120 is provided with a driving control unit 121, and the driving control unit 121 can control the indoor fan according to the first control instruction sent by the display circuit 110, so the driving control unit 121 is integrated into the indoor fan circuit 120. Because the functions of the indoor main control board have been realized by the display circuit 110 and the indoor fan circuit 120, the indoor main control board can be cancelled.

[0042] In the above embodiment, the driving part of the fan in the indoor main control board is integrated into the indoor fan circuit, and the control part and the communication part of the indoor main control board are integrated into the display circuit, thereby eliminating the indoor main control, which not only simplifies the connection relationship of the air conditioner, but also reduces the cost of the air conditioner, and saves the internal space of the indoor unit.

[0043] In some embodiments, Figure 2 and Figure 3 As shown, the air conditioner 1000 also includes: a bus 300, a first wiring terminal CN1 and a second wiring terminal CN2, wherein the bus 300 is respectively connected to the power output terminal (DC+_out and DC-_out) of the outdoor unit control circuit 210 and the communication interface of the outdoor unit control circuit 210; one end of the first wiring terminal CN1 is connected to the bus 300, and the other end of the first wiring terminal CN1 is respectively connected to the power input terminal (DC+_in and DC-_in) of the display circuit 110 and the communication interface of the display circuit 110; one end of the second wiring terminal CN2 is connected to the bus 300, and the other end of the second wiring terminal CN2 is connected to the power input terminal (DC+_in and DC-_in) of the indoor fan circuit 120.

[0044] Specifically, the power output end of the outdoor unit control circuit 210 includes a DC positive output end DC+_out of the outdoor unit control circuit 210 and a DC negative output end DC-_out of the outdoor unit control circuit 210, respectively, the power input end of the display circuit 110 and the power input end of the indoor fan circuit 120 include a DC positive input end DC+_in and a DC negative input end DC-_in, respectively, and the DC positive output end DC+_out of the outdoor unit control circuit 210, the DC negative output end DC-_out of the outdoor unit control circuit 210 and the communication interface of the outdoor unit control circuit 210 are connected to the bus 300 through a 3-core weak current connection line group. Because the working current of the indoor fan is relatively large when working, and the working current of the display circuit 110 is relatively small, the indoor fan circuit 120 and the display circuit 110 need to be connected to the bus 300 respectively, so the air conditioner 1000 is provided with two wiring terminals, namely, a first wiring terminal CN1 and a second wiring terminal CN2. The first wiring terminal CN1 has three pins, one end of the first wiring terminal CN1 is connected to the bus 300, and the other end of the first wiring terminal CN1 is respectively connected to the DC positive input terminal DC+_in of the display circuit 110, the DC negative input terminal DC-_in of the display circuit 110, and the communication interface of the display circuit 110. Because the indoor fan circuit 120 does not need to communicate with the outdoor unit control circuit 210, the second wiring terminal CN2 has two pins, one end of the second wiring terminal CN2 is connected to the bus 300, and the other end of the second wiring terminal CN2 is respectively connected to the DC positive input terminal DC+_in of the indoor fan circuit 120 and the DC negative input terminal DC-_in of the indoor fan circuit 120.

[0045] It should be noted that the communication interface of the outdoor unit control circuit 210 is connected to the bus 300 through the communication line S, and the communication interface of the display circuit 110 is connected to the first connection terminal CN1 through the communication line S.

[0046] In the above embodiment, the indoor unit and the outdoor unit are connected via a bus, and the bus is provided with two terminals according to the current on the indoor side, one terminal is connected to the display circuit, and the other terminal is connected to the indoor fan circuit.

[0047] In some embodiments, Figure 4 and Figure 5As shown, the power input terminal (DC+_in and DC-_in) of the indoor fan circuit 120 is connected to the power output terminal (DC+_out and DC-_out) of the outdoor unit control circuit 210, and the power output terminal (DC+_out and DC-_out) of the indoor fan circuit 120 is connected to the power input terminal (DC+_in and DC-_in) of the display circuit 110, wherein the power input terminal (DC+_in and DC-_in) of the indoor fan circuit 120 is connected to the power output terminal (DC+_out and DC-_out) of the indoor fan circuit 120.

[0048] Specifically, the outdoor unit 200 and the indoor unit 100 may not be connected via the bus 300 , but the outdoor unit control circuit 210 is directly connected to the indoor fan circuit 120 , and then the indoor fan circuit 120 is connected to the display circuit 110 . The DC positive output terminal DC+_out of the outdoor unit control circuit 210 is connected to the DC positive input terminal DC+_in of the indoor fan circuit 120, the DC negative output terminal DC-_out of the outdoor unit control circuit 210 is connected to the DC negative input terminal DC-_in of the indoor fan circuit 120, the DC positive output terminal DC+_out of the indoor fan circuit 120 is connected to the DC positive input terminal DC+_in of the indoor fan circuit 120, the DC negative output terminal DC-_out of the indoor fan circuit 120 is connected to the DC negative input terminal DC-_in of the indoor fan circuit 120, the DC positive input terminal DC+_in of the display circuit 110 is connected to the DC positive output terminal DC+_out of the indoor fan circuit 120, and the DC negative input terminal DC-_in of the display circuit 110 is connected to the DC negative output terminal DC-_out of the indoor fan circuit 120.

[0049] In some embodiments, Figure 4 and Figure 5 As shown, the outdoor unit control circuit 210 is connected to the display circuit 110 via a communication line S.

[0050] It can be understood that when the power output end of the outdoor unit control circuit 210 is directly connected to the power input end of the indoor fan circuit 120, and the power output end of the indoor fan circuit 120 is connected to the power input end of the display circuit 110, in order to ensure normal communication between the outdoor unit 200 and the indoor unit 100, the communication interface of the outdoor unit control circuit 210 is connected to the communication interface of the display circuit 110 through a communication line S.

[0051] In some embodiments, Figure 3 and Figure 5As shown, the indoor fan circuit 120 also includes: a first voltage conversion unit 123, the input end of the first voltage conversion unit 123 is suitable for inputting direct current, the output end of the first voltage conversion unit 123 is connected to the drive control unit 121, and the first voltage conversion unit 123 is configured to generate a first direct current according to the direct current, and provide the first direct current to the drive control unit 121, so that the drive control unit 121 drives the indoor fan motor 122 according to the first direct current.

[0052] Specifically, the DC power provided by the outdoor unit control circuit 210 may not meet the working voltage of the indoor fan motor 122. Therefore, the first voltage conversion unit 123 is required to perform voltage conversion on the DC power to obtain the first DC power to power the indoor fan motor 122. Figure 3 When the connection shown in FIG. 1 is used, the input end of the first voltage conversion unit 123 is connected to the second wiring terminal CN2; Figure 5 In the connection shown, the input end of the first voltage conversion unit 123 is directly connected to the power output end (DC+_out and DC-_out) of the outdoor unit control circuit 210.

[0053] Optionally, the first voltage conversion unit 123 includes a first switch tube Q1, a first inductor L1, a first diode D1 and a first capacitor C1, wherein the first end of the first switch tube Q1 is the DC positive input terminal DC+_in of the indoor fan circuit 120, the second end of the first switch tube Q1 is respectively connected to one end of the first inductor L1 and the cathode of the first diode D1, the other end of the first inductor L1 is connected to one end of the first capacitor C1, the other end of the first capacitor C1 is connected to the anode of the first diode D1 and then grounded, and is the DC negative input terminal DC-_in of the indoor fan circuit 120. When the first switch tube Q1 is turned on, the first inductor L1 starts to store energy and the first capacitor C1 starts to charge; when the first switch tube Q1 is turned off, the first inductor L1 releases electric energy to the first capacitor C1 and the drive control unit 121, the first capacitor C1 is used to filter the first DC power, and the first diode D1 is used for freewheeling.

[0054] In some embodiments, Figure 3 and Figure 5As shown, the drive control unit 121 includes: a control module 1211 and a drive module 1212, wherein the input end of the control module 1211 is connected to the output end of the display circuit 110, and the control module 1211 is configured to receive a first control instruction and generate a first drive signal according to the first control instruction; the input end of the drive module 1212 is connected to the output end of the first voltage conversion unit 123, the output end of the drive module 1212 is connected to the indoor fan motor 122, the control end of the drive module 1212 is connected to the output end of the control module 1211, and the drive module 1212 is configured to drive the indoor fan motor 122 according to the first drive signal.

[0055] Specifically, the control module 1211 is connected to the display circuit 110 to receive the first control instruction sent by the display circuit 110, and generates a first drive signal according to the first control instruction. The drive module 1212 is connected to the first voltage conversion unit 123 to receive the electric energy provided by the first voltage conversion unit 123, and then drives the indoor fan motor 122 according to the first drive signal. The drive module 1212 can be an inverter, and the inverter controls the corresponding switch tube to close according to the drive signal to provide the first direct current to the indoor fan motor 122, so that the indoor fan motor 122 rotates.

[0056] In some embodiments, Figure 3 and Figure 5 As shown, the drive control unit 121 is connected to the display circuit 110 via a serial port, and the drive control unit 121 is also configured to feed back the current operating status of the indoor fan motor 122 to the display circuit 110 so that the display circuit 110 generates a first control instruction according to the current operating status.

[0057] Specifically, the data transmission pin TXD of the display circuit 110 is connected to the data receiving pin RXD of the drive control unit 121, and the data receiving pin RXD of the display circuit 110 is connected to the data transmission pin TXD of the drive control unit 121. The display circuit 110 sends a first control command to the data receiving pin RXD of the drive control unit 121 through the data transmission pin TXD of the display circuit 110 to control the wind speed of the indoor fan. The drive control unit 121 sends the current operating state of the indoor fan motor 122 to the data receiving pin RXD of the display circuit 110 through the data transmission pin TXD of the drive control unit 121. The display circuit 110 can monitor the fault information, indoor fan speed and indoor fan power of the indoor fan according to the current operating state, and control the indoor fan according to the current operating state.

[0058] In the above embodiment, the display circuit controls the indoor fan circuit through the serial port. The serial port can not only control the indoor fan, but also monitor the current operating status of the indoor fan, thereby improving the accuracy of control. However, this method has higher requirements on the performance of the motor.

[0059] In some embodiments, Figure 3 and Figure 5 As shown, the speed control terminal VSP of the driving control unit 121 is connected to the output terminal of the display circuit 110, the feedback terminal FG of the driving control unit 121 is connected to the input terminal of the display circuit 110, and the display circuit 110 is also configured to send a first control instruction to the speed control terminal VSP.

[0060] Specifically, the display circuit 110 can control the indoor fan not only through the serial port, but also by sending a PWM (Pulse Width Modulation) signal to the drive control unit 121. The indoor fan circuit 120 has a speed control terminal VSP, and the display circuit 110 can be directly connected to the speed control terminal VSP of the drive control unit 121 to send a first control instruction to the speed control terminal VSP of the drive control unit 121, wherein the first control instruction is a PWM signal.

[0061] In the above embodiment, the display circuit controls the indoor fan circuit by means of PWM signals. This control method has low requirements on the performance of the motor, but cannot monitor the current operating status of the indoor fan.

[0062] In some embodiments, Figure 3 and Figure 5 As shown, the display circuit 110 includes: a display device 111, at least one stepper motor 112, a sterilization module 113, a first control unit 114, a first communication unit 115 and a second voltage conversion unit 116, wherein the display device 111 is suitable for displaying the current operating status of the air conditioner 1000; at least one stepper motor 112 is suitable for adjusting the air outlet angle of the indoor unit 100; the first control unit 114 is respectively connected to the display device 111 and the at least one stepper motor 112 to control the display device 111 and the at least one stepper motor 112 respectively; the first communication unit 115 is connected to the first control unit 114 and is in communication connection with the outdoor unit control circuit 210, and the first communication unit 115 is configured to send a second control instruction to the outdoor unit control circuit 210; the second voltage conversion unit 116 is suitable for inputting direct current, and the second voltage conversion unit 116 is configured to generate a second direct current based on the direct current to power the first control unit 114.

[0063] Specifically, the display device 111 is an original component of the display circuit 110, and the stepper motor 112 and the first communication unit 115 are the weak current parts of the indoor main control board. The direct current provided by the outdoor unit control circuit 210 may not meet the power supply voltage of the active devices in the display circuit 110. Therefore, the second voltage conversion unit 116 is required to perform voltage conversion on the direct current to obtain the second direct current to power the first control unit 114. The second voltage conversion unit 116 can use the same voltage conversion circuit as the first voltage conversion unit 123.

The outdoor unit control circuit 210 can also send the operating status information of the outdoor unit load to the first control unit 114 through the first communication unit 115, so that the first control unit 114 generates the second control instruction according to the operating status information of the outdoor unit load.

[0064] In some embodiments, the display circuit 110 further includes: a sterilization module 113 , which is connected to the first control unit 114 , and is configured to sterilize the indoor environment according to a control signal of the first control unit 114 .

[0065] That is to say, the weak current part of the indoor main control board also includes a sterilization module 113. After the first control unit 114 is powered on, it controls the sterilization module 113, and the sterilization module 113 sterilizes the indoor environment.

[0066] In an optional embodiment, the display circuit 110 also includes a detection unit 117, a receiving unit 118, a WiFi (Wireless Fidelity) module 119, a voice module 130, an air conditioning system sensor 131, 485 communication 132, a speaker and a button 133.

[0068] In the above embodiment, because the ignition source part of the indoor main control board is set in the indoor fan circuit, and the weak current part of the indoor main control board is set in the display circuit, the rated power of the display circuit is relatively low, and the rated power does not exceed 15W, and there is no need for fireproof design. Therefore, there is no need to set fireproof sheet metal, thereby further reducing the cost of the air conditioner.
