Detailed ways

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

It should be noted that all actions to obtain signals, information or data in this application are carried out under the premise of complying with the corresponding data protection laws and policies of the country where the location is located, and with the authorization given by the corresponding device owner.

Fig. 1 is a flowchart showing a method for detecting an air conditioner failure according to an exemplary embodiment. As shown in Figure 1, the method includes the following steps.

In step S101, when the air conditioner is in the heating mode and the electric heating module of the indoor unit is in the running state, in response to receiving an auxiliary heating function shutdown command indicating that the electric heating module is turned off, the voltage at the output terminal of the auxiliary thermal relay is obtained , the current at the output end of the auxiliary thermal relay and the temperature of the electric heating module.

When the user's heating demand is high (such as winter), the electric heating module can be controlled to turn on when the air conditioner is in the heating mode to achieve rapid heating. The electric heating module can be turned on or off by controlling the auxiliary thermal relay. In multiple scenarios, the user can send an instruction to turn off the auxiliary heating function through a mobile terminal (such as a mobile phone) or a remote controller to instruct the electric heating module to turn off. For example, when the user controls to turn off the electric heating module, the control sends an auxiliary heating function shutdown instruction for instructing the electric heating module to turn off; when the user controls to turn off the air conditioner, the control sends an auxiliary heating function shutdown instruction for instructing 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 instruction to turn off the auxiliary heating function for instructing the electric heating module to turn off. After the air conditioner side receives the instruction to turn off the auxiliary heating function to indicate that the electric heating module is turned off, it can control to turn off the auxiliary thermal relay, and at the same time obtain the voltage at the output end of the auxiliary thermal relay, the current at the output end of the auxiliary thermal relay, and the temperature of the electric heating module. In the event of a sticking failure of the auxiliary thermal relay, there is a risk of fire.

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

The voltage at the output terminal of the auxiliary thermal relay, the current at the output terminal of the auxiliary thermal relay, and the temperature of the electric heating module are different before and after the adhesion fault of the auxiliary thermal relay occurs. For example, if the auxiliary thermal relay does not fail, the electric heating module stops running and the temperature stops After the auxiliary thermal relay has a sticking failure, the electric heating module is still working, and the temperature of the electric heating module continues to rise. After obtaining the voltage at the output terminal of the auxiliary thermal relay, the current at the output terminal of the auxiliary thermal relay and the temperature of the electric heating module, it can be determined whether the auxiliary thermal relay has a sticking failure according to the obtained voltage, current and temperature

Through the above technical solution, when the air conditioner is in the heating mode and the electric heating module of the indoor unit is in the running state, the voltage at the output terminal of the auxiliary thermal relay is obtained in response to receiving the auxiliary heating function shutdown instruction for instructing the electric heating module to be turned off , the current at the output end of the auxiliary thermal relay and the temperature of the electric heating module.

In yet another embodiment, determining whether a sticking fault occurs in the auxiliary thermal relay according to the obtained voltage, current and temperature includes:

If 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 is determined that the auxiliary thermal relay has a sticking failure.

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 where the electric heating module is located is in conduction state, the electric heating module is in the running state, and the temperature of the electric heating module is relatively high, so it can be determined that the auxiliary thermal relay has a sticking failure. 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 where the electric heating module is located is disconnected, and the electric heating module stops Therefore, it can be determined that the auxiliary thermal relay has not had a sticking failure. The current threshold can be preset by the designer, for example, it can be 0.5A. The first temperature threshold can be preset by a designer, for example, it can be 75°C.

In this embodiment, the sticking failure of the auxiliary thermal relay can be accurately and reliably determined through simple threshold value comparison, and the data processing speed is fast and the reliability is high.

In yet another embodiment, the above method also includes:

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

After it is determined that the auxiliary thermal relay has a sticking fault, a prompt message including fault type information may be output.

The fault type is a sticking fault of the auxiliary thermal relay.

In this embodiment, after it is determined that the auxiliary thermal relay has a sticking fault, a prompt message including fault type information is output to facilitate the user to take corresponding measures in time, thereby improving safety.

In yet another embodiment, the above method also includes:

If it is determined that the auxiliary thermal relay has a sticking failure, then send a first alarm instruction 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 thermal relay has a sticking failure, then send a second alarm to the server Instructions, 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.

The first alarm command is used to instruct the user terminal to output an alarm message. After it is determined that the auxiliary thermal relay has a sticking failure, it can send the first alarm command to the user terminal (such as a mobile phone).

The air conditioner and the user terminal can communicate through Bluetooth, WIFI, 3G, 4G, 5G, etc.

It is also possible to send a second alarm instruction to the server after it is determined that the auxiliary thermal relay has a sticking failure, and the second alarm instruction is used to instruct the server to send a message for instructing the user terminal to output an alarm message to a user terminal (such as a mobile phone) associated with the air conditioner.

After receiving the third alarm instruction, the user terminal can output a pop-up message on the screen: "The auxiliary thermal relay has a sticking failure, please cut off the power supply of the air conditioner in time".

In this embodiment, the air conditioner directly communicates with the user terminal or communicates with the user terminal 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 air conditioner.

It is also possible to give priority to sending the first alarm command to the user terminal. When the user terminal receives the first alarm command sent by the air conditioner, it can feed back a response message to the air conditioner. If the communication between the air conditioner and the user terminal fails, the air conditioner will If no response message fed back by the user terminal is received, a second alarm instruction for instructing the server to send a third alarm instruction to the user terminal associated with the air conditioner may be sent to the server.

In this embodiment, through the above two mutually redundant methods for instructing the user terminal to output an alarm message, when one of the methods cannot cause the user terminal to output an alarm message, the other redundant method can reliably , effectively instructing the user terminal to output an alarm message.

When it is determined that the auxiliary thermal relay has a sticking fault, the first alarm command can be sent to the user terminal while the air conditioner terminal outputs a fault prompt message, or the second alarm command can be sent to the server while the air conditioner terminal outputs a fault prompt message, It is also possible to send the first alarm instruction to the user terminal and the second alarm instruction to the server while the air conditioner terminal outputs the fault prompt message. Alternatively, outputting a fault prompt message, sending the first alarm command, and sending the second alarm command may be executed in any order, which is not limited here.

The predetermined duration may be preset by the designer, for example, it may be 3 minutes. When the timing period from the determination that the auxiliary thermal relay has a sticking fault reaches the predetermined time, and the air conditioner is powered on 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 sticking fault and continues The duration is longer, the air conditioner is powered on (the user has not cut off the power supply of the air conditioner), the electric heating module is continuously running, and the temperature of the electric heating module is high, there is a risk of fire. You can control the air conditioner in cooling mode and While running at the maximum power, the internal fan of the air conditioner is controlled to run at the maximum speed to reduce the temperature of the electric heating module. The second temperature threshold can be preset by a designer, for example, it can be 100°C.
