[0035] Figure 4 The invention is a block diagram showing a device for detecting air conditioner faults according to an exemplary embodiment. DETAILED DESCRIPTION

[0036] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0037] It should be noted that all actions of acquiring signals, information or data in this application are carried out in compliance with the relevant data protection laws and policies of the country where they are located, and with the authorization given by the owner of the corresponding device.

[0038] Figure 1 FIG. 1 is a flow chart showing a method for detecting air conditioner failure according to an exemplary embodiment. Figure 1 As shown, the method includes the following steps.

[0039] In step S101, when the air conditioner is in heating mode and the electric heating module of the indoor unit is in operation, in response to receiving an auxiliary heating function shutoff instruction for instructing the electric heating module to shut down, the voltage at the auxiliary heating relay output terminal, the current at the auxiliary heating relay output terminal and the temperature of the electric heating module are obtained.

[0040] When the user's heating demand is high (for example, in winter), the electric heating module can be controlled to be turned on to achieve rapid heating when the air conditioner is in heating mode. The electric heating module can be turned on or off by the auxiliary heating relay. In multiple scenarios, the user can send an auxiliary heating function off instruction to instruct the electric heating module to turn off through a mobile terminal (such as a mobile phone) or a remote control. For example, when the user controls to turn off the electric heating module, the control sends an auxiliary heating function off instruction to instruct the electric heating module to turn off; when the user controls to turn off the air conditioner, the control sends an auxiliary heating function off instruction to instruct the electric heating module to turn off; when the user adjusts the working mode of the air conditioner from the heating mode to the cooling mode, the control sends an auxiliary heating function off instruction to instruct the electric heating module to turn off. After receiving the auxiliary heating function off instruction to instruct the electric heating module to turn off, the air conditioner side can control the disconnection of the auxiliary heating relay and obtain the voltage at the output end of the auxiliary heating relay, the current at the output end of the auxiliary heating relay and the temperature of the electric heating module. If the auxiliary heating relay has a sticking fault, there is a risk of fire.

[0041] In step S102, it is determined whether a sticking fault occurs in the auxiliary thermal relay according to the acquired voltage, current and temperature.

[0042] The voltage at the output end of the auxiliary heating relay, the current at the output end of the auxiliary heating relay, and the temperature of the electric heating module are different before and after the auxiliary heating relay has a sticking failure. For example, if the auxiliary heating relay has not failed, the electric heating module stops running and the temperature stops rising. After the auxiliary heating relay has a sticking failure, the electric heating module is still in operation and the temperature of the electric heating module continues to rise. After obtaining the voltage at the output end of the auxiliary heating relay, the current at the output end of the auxiliary heating relay, and the temperature of the electric heating module, it is possible to determine whether the auxiliary heating relay has a sticking failure based on the obtained voltage, current, and temperature.

[0043] Through the above technical solution, when the air conditioner is in heating mode and the electric heating module of the indoor unit is in operation, in response to receiving the auxiliary heating function shutdown instruction for instructing the electric heating module to shut down, the voltage at the output end of the auxiliary heating relay, the current at the output end of the auxiliary heating relay and the temperature of the electric heating module are obtained, and based on the obtained voltage, current and temperature, it is possible to accurately and reliably determine that the auxiliary heating relay has a adhesion failure, thereby reducing the risk of fire caused by excessive temperature of the electric heating module due to adhesion failure of the auxiliary heating relay and improving safety.

[0044] In yet another embodiment, the above-mentioned determining whether the auxiliary heating relay has a sticking fault according to the acquired voltage, current and temperature includes:

[0045] If the acquired voltage is not less than a predetermined voltage threshold, the acquired current is not less than a predetermined current threshold, and the acquired temperature is not less than a predetermined first temperature threshold, it is determined that a sticking fault occurs in the auxiliary thermal relay.

[0046] The voltage threshold can be preset by the designer, for example, it can be 50V. When the obtained voltage is not less than the predetermined voltage threshold, the obtained current is not less than the predetermined current threshold and the obtained temperature is not less than the predetermined first temperature threshold, it can be determined that the electric heating circuit in which the electric heating module is located is in a conducting state, the electric heating module is in an operating state, and the temperature of the electric heating module is high, so it can be determined that the auxiliary heating relay has a adhesion fault. When the obtained voltage is less than the predetermined voltage threshold, the obtained current is less than the predetermined current threshold and the obtained temperature is less than the predetermined first temperature threshold, it can be determined that the electric heating circuit in which the electric heating module is located is open, and the electric heating module stops running, so it can be determined that the auxiliary heating relay has no adhesion fault. The current threshold can be preset by the designer, for example, it can be 0.5A. The first temperature threshold can be preset by the designer, for example, it can be 75°C.

[0047] In this embodiment, a simple threshold comparison can be used to accurately and reliably determine that the auxiliary thermal relay has a sticking fault, and the data processing speed is fast and the reliability is high.

[0048] In yet another embodiment, the above method further includes:

[0049] If it is determined that the auxiliary heating relay has a sticking fault, a fault prompt message is output, and the fault prompt message includes fault type information.

[0050] After determining that the auxiliary heating relay has a adhesion fault, a prompt message including fault type information can be output. For example, the buzzer can be controlled to turn on to remind the user that the air conditioner has a fault through sound, and at the same time, a pop-up message "auxiliary heating relay has a adhesion fault" can be controlled to be output on the indoor unit screen of the air conditioner. The fault type is an auxiliary heating relay adhesion fault.

[0051] In this embodiment, after determining that the auxiliary heating relay has a sticking fault, a prompt message including fault type information is output, which facilitates the user to take corresponding measures in a timely manner, thereby improving safety.

[0052] In yet another embodiment, the above method further includes:

[0053] If it is determined that the auxiliary heating relay has a adhesion failure, a first alarm instruction is sent to the user terminal, and the first alarm instruction is used to instruct the user terminal to output an alarm message; or, if it is determined that the auxiliary heating relay has a adhesion failure, a second alarm instruction is sent to the server, and the second alarm instruction is used to instruct the server to send a third alarm instruction to the user terminal associated with the air conditioner, and the third alarm instruction is used to instruct the user terminal to output an alarm message.

[0054] The first alarm instruction is used to instruct the user terminal to output an alarm message. After determining that the auxiliary heating relay has a sticking fault, the first alarm instruction can be sent to the user terminal (such as a mobile phone). After receiving the first alarm instruction, the user terminal can output a pop-up message on the screen: "The auxiliary heating relay has a sticking fault, please cut off the air conditioner power supply in time." The air conditioner and the user terminal can communicate through Bluetooth, WIFI, 3G, 4G, 5G, etc.

[0055] After determining that the auxiliary heating relay has a sticking fault, a second alarm instruction can be sent to the server, and the second alarm instruction is used to instruct the server to send a third alarm instruction to the user terminal (such as a mobile phone) associated with the air conditioner to instruct the user terminal to output an alarm message. After receiving the third alarm instruction, the user terminal can output a pop-up message on the screen: "The auxiliary heating relay has a sticking fault, please cut off the air conditioner power supply in time."

[0056] In this embodiment, the air conditioner communicates with the user terminal directly or through the server to instruct the user terminal to output an alarm message, which can remind the user in time and enhance the safety of the use of the air conditioner.

[0057] It is also possible to preferentially send a first alarm instruction to the user terminal. When the user terminal receives the first alarm instruction sent by the air conditioner, it can feedback a response message to the air conditioner. If a communication failure occurs between the air conditioner and the user terminal, and the air conditioner does not receive a response message feedback from the user terminal within a predetermined period of time, it can send a second alarm instruction to the server to instruct the server to send a third alarm instruction to the user terminal associated with the air conditioner.

[0058] In this embodiment, through the above two mutually redundant methods for instructing the user terminal to output an alarm message, when one method cannot enable the user terminal to output an alarm message, the other redundant method can reliably and effectively instruct the user terminal to output an alarm message.

[0059] When it is determined that the auxiliary heating relay has a sticking fault, the air conditioner terminal can send a first alarm instruction to the user terminal while outputting a fault prompt message, or send a second alarm instruction to the server while outputting a fault prompt message, or send a first alarm instruction to the user terminal and a second alarm instruction to the server while outputting a fault prompt message. Alternatively, the output of the fault prompt message, the sending of the first alarm instruction, and the sending of the second alarm instruction can be executed in any order, which is not limited here.

[0060] In yet another embodiment, the above method further includes:

[0061] When the timing duration starting from the determination that the auxiliary heating relay has a sticking fault reaches a predetermined duration, if the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than a predetermined second temperature threshold, the air conditioner is controlled to be in cooling mode and to operate at maximum power, and at the same time, the air conditioner's internal fan is controlled to operate at maximum speed, and the first temperature threshold is less than the second temperature threshold.

[0062] The predetermined duration can be preset by the designer, for example, it can be 3 minutes. When the timing duration from the determination that the auxiliary thermal relay has a adhesion fault reaches the predetermined duration, the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than the predetermined second temperature threshold, it is considered that the auxiliary thermal relay has a adhesion fault for a long time, the air conditioner is in a powered-on state (the user has not cut off the power of the air conditioner), the electric heating module is continuously in operation, and the temperature of the electric heating module is high, there is a risk of fire, and the air conditioner can be controlled to be in cooling mode and run at maximum power while controlling the air conditioner's internal fan to run at maximum speed to reduce the temperature of the electric heating module. The second temperature threshold can be preset by the designer, for example, it can be 100°C.

[0063] In this embodiment, when the timing duration starting from the determination of the adhesion failure of the auxiliary heating relay reaches a predetermined duration, the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than a predetermined second temperature threshold, by controlling the air conditioner to be in cooling mode and running at maximum power, and at the same time controlling the air conditioner's internal fan to run at the maximum speed, the temperature of the electric heating module can be reliably lowered, thereby reducing the risk of fire and improving safety.

[0064] In yet another embodiment, the above method further includes:

[0065] When the timing duration starting from the determination that the auxiliary heating relay has a sticking fault reaches a predetermined duration, if the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than a predetermined second temperature threshold, a fourth alarm instruction is sent to the server, and the fourth alarm instruction is used to instruct the server to output an alarm message.

[0066] The fourth alarm instruction is used to instruct the server to output an alarm message. When the timing time from the determination that the auxiliary heating relay has a adhesion failure reaches a predetermined time, the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than the predetermined second temperature threshold, the fourth alarm instruction can be sent to the server. After receiving the fourth alarm instruction, the server can output a pop-up message on the screen: "The auxiliary heating relay of the air conditioner of user XXX has a adhesion failure, please contact the user in time."

[0067] In this embodiment, when the timing duration starting from the determination of the adhesion failure of the auxiliary heating relay reaches a predetermined duration, the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than a predetermined second temperature threshold, a fourth alarm instruction is sent to the server, so that the after-sales staff of the air conditioner can contact the user in time, thereby improving safety.

[0068] In another embodiment, when the timing duration starting from the determination that the auxiliary heating relay has a sticking fault reaches a predetermined duration, if the air conditioner is in a powered-on state and the temperature of the electric heating module obtained is not less than a predetermined second temperature threshold, the air conditioner can be controlled to be in cooling mode and run at maximum power, and the internal fan of the air conditioner can be controlled to run at the maximum speed, while a fourth alarm instruction is sent to the server.

[0069] Figure 2 is a flow chart of an air conditioner fault detection method according to yet another exemplary embodiment. Figure 2 The steps in the embodiment are a combination of the steps in the above multiple embodiments, and specifically include the following steps.

[0070] 1. When the air conditioner is in heating mode and the electric heating module of the indoor unit is in operation, in response to receiving an auxiliary heating function shut-down instruction for instructing the electric heating module to shut down, the voltage at the auxiliary heating relay output terminal, the current at the auxiliary heating relay output terminal and the temperature of the electric heating module are obtained.

[0071] 2. If the obtained voltage is not less than 50V, the obtained current is not less than 0.5A and the obtained temperature is not less than 75°C, it is determined that the auxiliary heating relay has a sticking fault.

[0072] 3. If the voltage obtained is not less than 50V, the current obtained is not less than 0.5A and the temperature obtained is not less than 75°C, and at least one of the three is not satisfied, the detection is terminated.

[0073] 4. If it is determined that the auxiliary heating relay has a sticking fault, a fault prompt message is output and a first alarm instruction is sent to the user terminal at the same time.

[0074] 5. When the timing time from the determination of the adhesion failure of the auxiliary heating relay reaches 3 minutes, if the air conditioner is in the power-on state and the temperature of the electric heating module obtained is not less than 100°C, a fourth alarm instruction is sent to the server to control the air conditioner to be in cooling mode and run at maximum power, and at the same time control the air conditioner's internal fan to run at the maximum speed.

[0075] 7. When the timing time from the determination that the auxiliary heating relay has a sticking fault reaches 3 minutes, if the air conditioner is not in the power-on state or the temperature of the electric heating module obtained is less than 100°C, the detection is terminated.
