[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] The terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plural" is two or more.

[0029] In the description of the present invention, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] As Figure 1 shown, in the present invention, the air conditioner body 1 performs a refrigeration cycle by using a compressor, a condenser, an evaporator, and a four-way valve. The refrigeration cycle includes a series of processes involving compression, condensation, and evaporation, and supplies refrigerant to the air that has been conditioned and heat-exchanged.

[0031] The compressor compresses the refrigerant gas in a high-temperature and high-pressure state that enters from the suction pipe and discharges the compressed refrigerant gas through the discharge pipe. The discharged refrigerant gas flows into the condenser from the condenser inlet pipe. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0032] The evaporator evaporates the refrigerant that expands in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to perform heat exchange with the material to be cooled. Throughout the cycle, the air conditioner body 1 can adjust the temperature of the indoor space.

[0033] Combined with Figure 2 and Figure 4 shown, the air conditioner body 1 in the present application includes an indoor fan 11 and an outdoor fan 14. The indoor fan 11 and the outdoor fan 14 can be set as an integrated machine or a split machine. The indoor fan 11 can be set as a wall-mounted type, a ceiling type, a duct type, etc., and the indoor fan 11 is installed on the top or ceiling of the indoor room.

[0034] Taking the indoor wall-mounted unit as an example, the indoor wall-mounted unit is usually installed at positions such as the indoor wall surface. Again, for example, the indoor cabinet unit (not shown in the figure) is also a form of the indoor fan 11 of the indoor fan 11.

[0035] Taking the split machine as an example, the air conditioner body 1 includes an indoor fan 11 and an outdoor fan 14. Among them, the outdoor fan 14 is usually arranged outdoors and is used for heat exchange with the indoor environment.

[0036] In addition, the air conditioner body 1 is provided with a second controller 71 to control the operation of various components in the air conditioner body 1, so that the operation of each component of the air conditioner body 1 realizes each predetermined function of the air conditioner body 1. Among them, a control device 200 is also attached to the air conditioner body 1. Exemplarily, the control device 200 is specifically set as a remote controller 3, and the remote controller 3 has a function of communicating with the second controller 71 by using infrared rays or other communication methods. The remote controller 3 is used for the user to perform various controls on the air conditioner body 1, realizing the interaction between the user and the air conditioner body 1.

[0037] In the embodiment of the present application, the indoor fan 11 of the air conditioner body 1 is arranged at the top or upper part of the room. Generally speaking, the installation height of the indoor fan 11 is higher than the user activity area. The indoor fan 11 includes an air return opening 13 and an air outlet 12 communicating with the room. The indoor air passes through the air return opening 13 into the indoor fan 11 and flows back into the room through the air outlet 12.

[0038] At the position of the air outlet 12, a wind deflector 2 is provided. The wind deflector 2 adjusts the outflow direction of the air flowing through the air outlet 12 by changing its relative rotation angle with the air outlet 12, thereby affecting the air temperature stratification in the room.

[0039] The embodiment of the present application also provides a schematic diagram of the hardware structure of the second controller 71, as Figure 3 shown. The second controller 71 includes a processor 83. Optionally, it further includes a memory 82 and a communication interface 84 connected to the processor 83. The processor 83, the memory 82 and the communication interface 84 are connected through a bus 81.

[0040] The processor 83 may be a central processing unit (CPU), a general-purpose processor, a network processor (NP), a digital signal processor (DSP), a microprocessor, a microcontroller, a programmable logic device (PLD), or any combination thereof. The processor 83 may also be any other device with processing functions, such as a circuit, a device, or a software module. The processor 83 may also include multiple CPUs, and the processor 83 may be a single-core (single CPU) processor or a multi-core (multi CPU) processor. Here, the processor 83 may refer to one or more devices, circuits, or processing cores for processing data (such as computer program instructions).

[0041] The memory 82 can be a read only memory (ROM), or other types of static storage devices that can store static information and instructions, a random access memory (RAM), or other types of dynamic storage devices that can store information and instructions. It can also be an electrically erasable programmable read only memory (EEPROM), a compact disc read only memory (CD ROM), or other optical disc storage, optical disc storage (including compact discs, laser discs, optical discs, digital versatile discs, Blu-ray discs, etc.), magnetic disk storage media, or other magnetic storage devices, or any other medium that can be used to carry or store the desired program code in the form of instructions or data structures and can be accessed by a computer. The embodiments of the present application do not impose any restrictions on this. The memory 82 can exist independently or be integrated with the processor 83. Among them, the memory 82 can contain computer program code. The processor 83 is used to execute the computer program code stored in the memory 82, thereby implementing the control method of the air conditioner body 1 provided by the embodiments of the present application.

[0042] The communication interface 84 can be used to communicate with other devices or communication networks (such as Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc.). The communication interface 84 can be a module, a circuit, a transceiver, or any device capable of implementing communication.

[0043] The bus 81 can be a peripheral component interconnect (PCI) bus 81 or an extended industry standard architecture (EISA) bus 81, etc. The bus 81 can be divided into an address bus 81, a data bus 81, a control bus 81, etc.

[0044] Next, in conjunction with Figures 4 - 6 Describe the air conditioner 100 and its control method according to the embodiments of the present invention.

[0045] As Figure 4 shown, the air conditioner 100 includes: an air conditioner body 1, a remote controller 3;

[0046] Among them, in some embodiments, the air conditioner main body 1 may include: a refrigerant circulation circuit that enables the refrigerant to perform a refrigeration cycle in a circuit composed of a compressor, a condenser, an expansion valve, and an evaporator, where one of the condenser and the evaporator is an outdoor heat exchanger and the other is an indoor heat exchanger.

[0047] In some embodiments, the air conditioner main body 1 may include: an indoor fan 11 configured to drive indoor air to pass through the indoor heat exchanger by rotation, so that the refrigerant exchanges heat with the indoor air.

[0048] In some embodiments, the air conditioner main body 1 may include: an outdoor fan 14 configured to drive outdoor air to pass through the outdoor heat exchanger by rotation, so that the refrigerant exchanges heat with the outdoor air.

[0049] In some embodiments, as Figure 4 shown, the remote controller 3 may include: a first controller 31 configured to: when it is determined that a first preset condition is met, control the remote controller 3 to enter a header code information modification mode to modify the header code information of the remote controller 3, and after the modification is completed, send the modified header code information to the second controller 71.

[0050] Specifically, a first controller 31 is provided inside the remote controller 3. After the remote controller 3 is powered on, the first controller 31 can continuously detect whether the remote controller 3 meets the conditions for entering the header code information modification mode, that is, the first preset condition, including but not limited to whether the user long-presses a certain specific key combination, whether any operation signal is received within a specific time, etc. Further, when it is determined that the first preset condition is met, the remote controller 3 can be controlled to enter the header code information modification mode, and the header code information of the remote controller 3 can be customized according to the user's needs. After the modification is completed, the first controller 31 can send the modified header code information to the second controller 71 of the air conditioner main body 1 through wireless communication or other means.

[0051] In some embodiments, as Figure 4 shown, the air conditioner main body 1 may include: a second controller 71 configured to: when it is determined that a second preset condition is met, receive the modified header code information sent by the first controller 31, verify the received modified header code information, and store the modified header code information after successful verification;

[0052] When a control signal sent by the remote controller 3 is received, determine whether the header code information in the control signal is the same as the modified header code information stored in the second controller 71;

[0053] If so, control the air conditioner main body 1 to operate according to the control signal, otherwise, control the air conditioner main body 1 to maintain the current operating state.

[0054] Specifically, a second controller 71 is provided inside the air conditioner body 1. The second controller 71 can continuously detect whether the condition for communicating with the first controller 31 is met, that is, the second preset condition. When it is determined that the second preset condition is met, the second controller 71 can receive the modified header code information sent by the first controller 31 and verify the received modified header code information, including but not limited to checksum comparison, etc., to ensure that the modified header code information is not damaged or tampered with during transmission. Further, after successful verification, the second controller 71 can store the modified header code information in a storage medium, including but not limited to storing it in an EEPROM (Electrically Erasable Programmable Read-Only Memory).

[0055] Further, when the air conditioner body 1 receives a control signal (such as a temperature adjustment signal, a mode switching signal, etc.) sent by the remote controller 3, the second controller 71 of the air conditioner body 1 can analyze the data in the control signal, extract the header code information in the control signal, and compare it with the modified header code information stored in the storage medium of the air conditioner body 1. If the header code information in the received control signal is consistent with the modified header code information stored in the storage medium, it indicates that the control signal comes from the correct and paired remote controller 3. At this time, the second controller 71 can control the air conditioner body 1 to execute the operations in the control signal, including but not limited to adjusting the wind speed, changing the temperature setting, etc.; if the header code information in the received control signal is inconsistent with the modified header code information stored in the storage medium, it indicates that the control signal does not come from the paired remote controller 3. At this time, the second controller 71 can ignore the control signal and control the air conditioner body 1 to maintain the current operating state.

[0056] According to the air conditioner 100 of an embodiment of the present invention, when it is determined that the first preset condition is satisfied, the first controller 31 in the remote controller 3 can customize and modify the header code information of the remote controller 3, and after the modification is completed, send the modified header code information to the second controller 71 of the air conditioner main body 1. When it is determined that the second preset condition is satisfied, the second controller 71 in the air conditioner main body 1 can receive the modified header code information and store it after successfully verifying the modified header code information. Further, when the second controller 71 receives a control signal sent by the remote controller 3, if it is determined that the header code information in the control signal is the same as the modified header code information stored by the second controller 71, the air conditioner main body 1 is controlled to operate according to the control signal; otherwise, the air conditioner main body 1 is controlled to maintain the current state, so as to avoid the phenomenon of misoperation when the air conditioner main body 1 receives a control signal sent by an unmatched remote controller 3, ensure that when there are multiple air conditioner main bodies 1, each air conditioner main body 1 can only respond to the commands of its exclusive remote controller 3, reduce the possibility of signal interference, improve the control accuracy of the remote controller 3 for the air conditioner main body 1, and further improve the reliability of the air conditioner 100.

[0057] In an embodiment of the present invention, after the remote controller 3 is controlled to enter the header code information modification mode, the first controller 31 is configured to: modify the values of the respective header codes in the header code information.

[0058] Specifically, after the remote controller 3 is controlled to enter the header code information modification mode, the first controller 31 can modify the values of the respective header codes in the header code information according to the values customized by the user, that is, replace the original values of the respective header codes with new values. For example, after the remote controller 3 enters the header code information modification mode, the display screen of the remote controller 3 can display the header code information. If each header code consists of two bytes, the values of the two bytes of each header code can be adjusted one by one to complete the modification of the values of the respective header codes. Among them, the range of each byte is usually 00 to FF (that is, 0 to 255 in decimal).

[0059] In an embodiment of the present invention, when modifying the values of the respective header codes in the header code information, the first controller 31 is configured to: modify the values of the respective header codes according to the received header code information modification instruction, where the header code information modification instruction includes the value adjustment amount corresponding to each header code.

[0060] Specifically, when modifying the values of each header code in the header code information, the first controller 31 can receive a header code information modification instruction through the communication channel inside the remote controller 3, and modify the values of each header code according to the header code information modification instruction. Among them, the header code information modification instruction includes the value adjustment amount corresponding to each header code, that is, the numerical amount by which each header code is increased or decreased. For example, the first controller 31 can determine the positions of the header codes to be modified in the header code information, read the current values of each header code, and then increase or subtract the value adjustment amount of each header code from the current value according to the indication in the header code information modification instruction, so as to achieve the modification of the values of each header code.

[0061] In an embodiment of the present invention, the header code information modification instruction is generated based on the user's operation on the corresponding button of the remote controller 3.

[0062] Specifically, when the first controller 31 modifies the header code information, a header code information modification instruction can be generated by pressing the corresponding button on the remote controller 3. For example, the user can determine each header code in the header code information to be modified by continuously pressing a certain button or a combination of buttons on the remote controller 3, and generate a corresponding header code information modification instruction by means of up and down selection of the button, digital input, etc., so that the first controller 31 can input the value adjustment amount of the corresponding header code according to the header code information modification instruction.

[0063] In an embodiment of the present invention, when verifying the received modified header code information, the second controller 71 is configured to: determine the first data frame checksum corresponding to the received modified header code information; compare the first data frame checksum with the received second data frame checksum, where the second data frame checksum is calculated by the first controller 31 based on the modified header code information;

[0064] When the first data frame checksum and the second data frame checksum are equal, it is determined that the verification of the received modified header code information is successful; otherwise, it is determined that the verification of the received modified header code information fails, and the modified header code information is not stored.

[0065] Specifically, when verifying the received modified header code information, the second controller 71 can recalculate and determine the data frame checksum of the modified header code information, that is, the first data frame checksum, through cyclic redundancy code check or parity check, etc. Further, the first data frame checksum can be compared with the received second data frame checksum, where the second data frame checksum is calculated by the first controller 31 before sending the modified header code information based on the modified header code information.

[0066] Further, when it is determined that the first data frame checksum is equal to the second data frame checksum, it indicates that the modified header code information received by the second controller 71 has not been in error or tampered with during transmission, and the verification is determined to be successful. The second controller 71 stores the received modified header code information. When it is determined that the first data frame checksum is not equal to the second data frame checksum, it indicates that the modified header code information has been in error or tampered with during data transmission, and the verification is determined to be failed. The second controller 71 does not store the modified header code information and maintains the original header code information unchanged to prevent incorrect configuration caused by wireless transmission errors or external interference and improve the reliability of the air conditioner 100.

[0067] In an embodiment of the present invention, when verifying the received modified header code information, the second controller 71 is further configured to: when the verification is successful, output a first preset prompt message corresponding to the successful verification; when the verification fails, output a second preset prompt message corresponding to the failed verification.

[0068] Specifically, when verifying the received modified header code information, if it is determined that the verification is successful, the second controller 71 may trigger a preset prompt message output mechanism to output a first preset prompt message corresponding to the successful verification, including but not limited to displaying text on the display screen (such as "Verification successful", etc.) or playing a sound through the buzzer (such as the buzzer can sound 3 times) to clearly inform the user that the verification has been successful; if it is determined that the verification fails, a second preset prompt message corresponding to the failed verification may be output, including but not limited to displaying text on the display screen (such as "Verification failed", etc.) or playing a sound through the buzzer (such as the buzzer can sound 5 times) to clearly inform the user that the verification has failed.

[0069] In an embodiment of the present invention, the first preset condition includes: the remote controller 3 receives a first preset signal within a first preset time, and the duration of the first preset signal within the first preset time exceeds a second preset time, where the first preset signal is emitted when a first preset button on the remote controller 3 is triggered.

[0070] Specifically, when the remote controller 3 is powered on, the timer inside the remote controller 3 starts timing. If the remote controller 3 receives a first preset signal within a first preset time, and the duration of the first preset signal within the first preset time exceeds a second preset time, it indicates that the user has a real intention to modify the header code information. At this time, it is determined that the remote controller 3 meets the first preset condition, where the first preset signal is emitted when a first preset button on the remote controller 3 is triggered. It can be understood that if within the first preset time, the user continuously presses the first preset button on the remote controller 3 for a time exceeding the second preset time, it can be determined that the first preset condition is met, thereby avoiding misoperations caused by accidental touches or short presses, and further improving the reliability of the air conditioner 100.

[0071] In a specific embodiment, the first preset time, the second preset time, and the first preset button can be set according to actual situations. Among them, the first preset time can be 10 seconds, the second preset time can be 3 seconds, and the first preset button can be the power-on button of the remote controller 3.

[0072] In an embodiment of the present invention, the second preset condition includes: the air conditioner main body 1 is in a powered-on state and receives the second preset signal sent by the remote controller 3 within the third preset time, where the second preset signal is sent when the second preset button on the remote controller 3 is triggered.

[0073] Specifically, when the air conditioner main body 1 is powered on, the timer inside the air conditioner main body 1 starts timing. If the second preset signal sent by the remote controller 3 is received within the third preset time, it indicates that the current air conditioner main body 1 can receive the modified header information sent by the first controller 31, that is, the second preset condition is satisfied. Among them, the second preset signal is sent when the second preset button on the remote controller 3 is triggered. It can be understood that after the air conditioner main body 1 is powered on, when it can detect that the user continuously presses the second preset button on the remote controller 3 within the third preset time, it can be determined that the second preset condition is satisfied, so as to avoid interference caused by other already turned-on air conditioner main bodies 1 to the air conditioner main body 1 that needs to modify the header information currently, and further improve the reliability of the air conditioner 100.

[0074] In a specific embodiment, the third preset time and the second preset button can be set according to actual situations. Among them, the third preset time can be 15 seconds, and the second preset button can be the power-on button of the remote controller 3.

[0075] In an embodiment of the present invention, when determining whether the header information in the control signal is the same as the modified header information stored in the second controller 71, the second controller 71 is further configured to: determine whether each header in the header information sent by the remote controller 3 corresponds one-to-one and is the same as each header in the modified header information stored in the second controller 71; if so, determine that the header information is the same, otherwise, determine that the header information is different.

[0076] Specifically, when the second controller 71 receives the control signal from the remote controller 3, it can extract the header information from the received control signal, and compare the extracted header information with the modified header information stored inside the second controller 71. If the values of each header of the header information sent by the remote controller 3 are exactly the same as the values of the corresponding headers stored in the second controller 71, it is determined that the header information is the same, otherwise, it is determined that the header information is different.

[0077] According to the air conditioner 100 of the embodiment of the present invention, when it is determined that the first preset condition is satisfied, the first controller 31 in the remote controller 3 can customize and modify the header code information of the remote controller 3, and after the modification is completed, send the modified header code information to the second controller 71 of the air conditioner body 1. When it is determined that the second preset condition is satisfied, the second controller 71 in the air conditioner body 1 can receive the modified header code information and store it after the verification of the modified header code information is successful. Further, when the second controller 71 receives the control signal sent by the remote controller 3, if it is determined that the header code information in the control signal is the same as the modified header code information stored in the second controller 71, the air conditioner body 1 is controlled to operate according to the control signal; otherwise, the air conditioner body 1 is controlled to maintain the current state. Therefore, it is possible to avoid the phenomenon of misoperation when the air conditioner body 1 receives the control signal sent by the unmatched remote controller 3, ensure that when there are multiple air conditioner bodies 1, each air conditioner body 1 can only respond to the commands of its exclusive remote controller 3, reduce the possibility of signal interference, and improve the control accuracy of the remote controller 3 for the air conditioner body 1, thereby improving the reliability of the air conditioner 100.
