[0023] Figure 2 It is the second of the flow schematic diagrams of the air conditioner drain pump fault detection method provided by the present invention.

[0024] Figure 3 It is the structural schematic diagram of the air conditioner drain pump fault detection device provided by the present invention.

[0025] Figure 4 It is the structural schematic diagram of the electronic device provided by the present invention. Detailed implementation manners

[0026] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0027] The following Figures 1 - 4 describes the air conditioner drain pump fault detection method and device of the present invention, and details its embodiments.

[0028] The following is a detailed description of the embodiments based on the air conditioner drain pump fault detection method described in the present invention. As Figure 1 shown, it is one of the flow schematic diagrams of the air conditioner drain pump fault detection method provided by the present invention, and the specific implementation process includes the following steps: Step 101: When the water level height of the condensate after detecting the refrigeration operation target time of the air conditioner does not exceed the warning water level height, obtain the current current data of the drain pump and the drainage flow data of the drainage pipe.

[0029] In an embodiment of the present invention, before performing this step, it is necessary to pre-detect the operating mode and operating time of the air conditioner. When the refrigeration operation target time of the air conditioner is detected, the water level height data collected by the liquid level control device in the condensate container is obtained. And the water level height data is compared and analyzed with a preset warning water level height. When the water level height data is less than the preset warning water level height, the current current data of the drain pump collected by the sampling resistor is obtained; when the water level height data is greater than or equal to the preset warning water level height, it is determined that the drain pump is in a fault state, and a corresponding drain pump fault alarm prompt message is generated. Among them, the operating mode may include, in addition to the refrigeration mode, a self-cleaning mode. The air conditioner generates condensate during the operation of the refrigeration mode and the self-cleaning mode, so it is necessary to control the drain pump to perform drainage operations. The air conditioner is a multi-connected air conditioner. The liquid level control device may be a float switch (i.e., the float in Figure 2 ) provided in the condensate storage container. Figure 2 in Figure 2

[0030] During the execution of this step, when it is detected that the water level height of the condensate after the refrigeration mode operation or the self-cleaning mode operation target time (such as 1 hour) of the air conditioner does not exceed the warning water level height, the current current data of the drain pump (i.e., the water pump in Figure 2 ) and the drainage flow data of the drainage pipe can be further obtained. Specifically, the current current data provided to the drain pump can be obtained through a preset sampling resistor, and the drainage flow data of the drainage pipe can be obtained through a flow sensor at the outlet of the drainage pipe. Figure 2 the water pump in Figure 2

[0031] Step 102: Based on the current current data of the drain pump, the drainage flow data of the drainage pipe, and the target drainage flow data corresponding to the drain pump, determine whether the drain pump is in a fault state. If so, generate a corresponding drain pump fault warning prompt message. Among them, the target drainage flow data is obtained based on the performance coefficient of the drain pump under the current current data and the maximum drainage volume corresponding to the drain pump; the performance coefficient is a parameter used to represent the drainage performance of the drain pump under the current current data.

[0032] In an embodiment of the present invention, the current current data (i.e., Figure 2 ) Figure 2The A1) in it is compared and analyzed with a preset target current range. When the current data is within the preset target current range, the first drainage flow rate data of the drainage pipeline collected by the flow sensor is obtained; further, the first drainage flow rate data is compared and analyzed with the first target drainage flow rate data corresponding to the drainage pump. When the first drainage flow rate data is less than the first target drainage flow rate data corresponding to the drainage pump, it is determined that the drainage pump is in a failure state, and a corresponding drainage pump failure alarm prompt message is generated. The smaller value of the target current range can be the no-load operating current data of the drainage pump (i.e., Figure 2 the A0) in it, and the larger value of the target current range can be the full-load operating current data of the drainage pump (i.e., Figure 2 the Am) in it.

[0033] Among them, the target drainage flow rate data includes the first target drainage flow rate data (i.e., Figure 2 the product of m and Lm in it). The first target drainage flow rate data is based on the first performance coefficient of the drainage pump under the current data (i.e., Figure 2 the m in it, where m is less than 1) and the maximum drainage volume corresponding to the drainage pump (i.e., Figure 2 the Lm) in it; the maximum drainage volume is a standard configuration parameter; the first performance coefficient is the coefficient of the corresponding relationship between each current data and each drainage flow rate data, and can be obtained by analyzing and processing multiple historical current data corresponding to the drainage pump and the historical drainage flow rate data corresponding to the drainage pump at each of the multiple historical current data, and is a parameter used to represent the drainage performance of the drainage pump under the current data.

[0034] After comparing and analyzing the first drainage flow rate data (i.e., Figure 2 the L1) in it with the first target drainage flow rate data corresponding to the drainage pump, it further includes: when the first drainage flow rate data is greater than or equal to the first target drainage flow rate data corresponding to the drainage pump and less than the maximum drainage volume corresponding to the drainage pump, it is determined that the drainage pump is operating normally, and the detection of the water level height data collected by the liquid level control device in the condensate container is continued for the next cycle.

[0035] In addition, the current data is compared and analyzed with a preset target current range. When the current data is outside the target current range, it is judged whether the current data is greater than the full-load operating current data of the drainage pump. When the current data (i.e., Figure 2 the A1) in it is greater than the full-load operating current data of the drainage pump (i.e., Figure 2 the Am) in it, the second drainage flow rate data of the drainage pipeline collected by the flow sensor can also be obtained (i.e., Figure 2in L2). By comparing and analyzing the second drainage flow rate data with the second target drainage flow rate data corresponding to the drainage pump (i.e., Figure 2 obtained by multiplying n and Lm in

[0036] ), when the second drainage flow rate data is greater than the second target drainage flow rate data corresponding to the drainage pump, it is determined that the drainage pump is in a fault state, and a corresponding drainage pump fault alarm prompt message is generated. Figure 2 wherein the target drainage flow rate data includes the second target drainage flow rate data. The second target drainage flow rate data is based on the second performance coefficient of the drainage pump under the current current data (i.e., Figure 2 n in

[0037] where n is less than or equal to 1) and the maximum drainage volume corresponding to the drainage pump (i.e.,

[0038] Lm in Figure 2 ). The maximum drainage volume is a standard configuration parameter. The second performance coefficient is the coefficient of the corresponding relationship between each current data and each drainage flow rate data, and can be obtained by analyzing and processing multiple historical current data corresponding to the drainage pump and the historical drainage flow rate data corresponding to the drainage pump at each of the multiple historical current data, and is a parameter used to represent the drainage performance of the drainage pump under the current current data. Figure 2 When the second drainage flow rate data is less than or equal to the second target drainage flow rate data corresponding to the drainage pump, it is determined that the drainage pump is operating normally, and the detection of the water level height data collected by the liquid level control device in the condensate container continues for the next cycle.

[0039] It should be noted that in the process of determining the performance coefficient corresponding to the drainage pump, multiple historical current data corresponding to the drainage pump (such as A1, A2... An) and historical drainage flow data corresponding to the drainage pump at a head of 1.2 meters corresponding to the multiple historical current data (such as L1, L2... Ln) can be obtained. Then, normal distribution analysis is performed on the multiple historical current data and the historical drainage flow data to obtain a normal distribution curve, and the corresponding performance coefficient can be obtained according to the normal distribution curve. In addition, linear fitting processing can also be performed on the multiple historical current data and the historical drainage flow data to obtain the corresponding performance coefficient.
