[0025] See attached Figure 1 , Figure 1 The following is a flow chart of the main steps of a method for detecting blockage in an air conditioner drain pipe according to an embodiment of the present invention. The air conditioner drain pipe includes an indoor drain pipe and an outdoor drain pipe. The indoor drain pipe and the outdoor drain pipe are connected via a pipe connecting device. The pipe connecting device includes a cavity for accommodating condensed water and a water level meter for detecting the condensed water level in the cavity. The condensed water generated during the operation of the air conditioner is discharged in sequence through the indoor drain pipe, the pipe connecting device, and the outdoor drain pipe. Figure 1 As shown, the method for detecting blockage of an air-conditioning drain pipe in an embodiment of the present invention mainly includes the following steps S101 to S105.

[0026] Step S101: After the air conditioner is started, the upper limit and lower limit of the condensed water level in the pipe communication device after running for a first preset time are predicted according to the operating mode of the air conditioner.

[0027] In this embodiment, the air conditioner can be any type of air conditioner that includes an indoor drainage pipe and an outdoor drainage pipe, and the indoor drainage pipe and the outdoor drainage pipe are connected through a pipe connecting device, such as a cabinet air conditioner, a hanging air conditioner, a vertical air conditioner, a mobile air conditioner or a commercial multi-split air conditioner, etc. The embodiment of the present invention does not limit this.

[0028] The operating modes of the air conditioner may include, but are not limited to, cooling mode, heating mode, dehumidification mode, and ventilation mode.

[0029] The first preset duration is used to predict the operating time required to generate the upper and lower limits of the condensed water level within the pipe communication device during operation of the air conditioner. The first preset duration can be a duration determined by those skilled in the art based on test data, or can be a duration determined by those skilled in the art by adjusting the preset duration based on actual needs, and this is not limited in the present embodiment.

[0030] The upper and lower limits are the maximum and minimum values used to determine whether condensate blockage has occurred within the pipe communication device. Both the upper and lower limits can be values obtained by those skilled in the art based on experimental data, or can be values obtained by those skilled in the art by adjusting the already set values based on actual needs. This is not a limitation in the present invention.

[0031] In one embodiment, after the air conditioner is started, the amount of condensed water generated by the air conditioner after running for a first preset time can be predicted based on the operating mode of the air conditioner. When the amount of condensed water reaches a first ratio of the volume of the cavity containing condensed water in the pipe connecting device, the amount of condensed water is determined as the lower limit of the condensed water level in the pipe connecting device. When the amount of condensed water reaches a second ratio of the volume of the cavity containing condensed water in the pipe connecting device, the amount of condensed water is determined as the upper limit of the condensed water level in the pipe connecting device.

[0032] Furthermore, those skilled in the art can predict the amount of condensed water generated by the air conditioner after running in different operating modes for a first preset time based on actual experience.

[0033] It should be noted that the first ratio is less than the second ratio and the difference between the first ratio and the second ratio is greater than a set threshold. Specifically, the first ratio refers to the ratio of the lower limit of the condensate level in the pipe connection device to the amount of condensate generated by the air conditioner; the second ratio refers to the ratio of the upper limit of the condensate level in the pipe connection device to the amount of condensate generated by the air conditioner; the set threshold is used to prevent the first ratio and the second ratio from being too close, causing the upper and lower limits of the condensate level to be too close, thereby reducing the accuracy of detecting blockage in the air conditioner drain pipe. The first ratio, the second ratio, and the set threshold can all be ratios obtained by those skilled in the art based on experimental data, or can be ratios obtained by those skilled in the art after adjusting the already set ratios according to actual needs. The present embodiment is not limited in this regard. For example, the first ratio can be 1 / 3, 1 / 4, 1 / 5, 1 / 6, etc., and the second ratio can be 2 / 3, 3 / 4, 4 / 5, 5 / 6, etc. Preferably, in the embodiment of the present invention, the first ratio is 1 / 3 and the second ratio is 4 / 5.

[0034] For example, if the air conditioner is started and the cooling mode is executed, the preset first time length is 20 minutes. Then, according to the prediction that the condensed water level generated by the air conditioner in the cavity containing the condensed water in the pipe connecting device reaches 60 cm after the cooling mode has been running for 20 minutes; the first ratio is set to 1 / 3, and the second ratio is set to 4 / 5. Then, the ratio of the lower limit value of the condensed water level in the pipe connecting device to the level of 60 cm of the condensed water generated by the air conditioner is the first ratio 1 / 3. Therefore, the lower limit value of the condensed water level in the pipe connecting device = the level of the condensed water generated by the air conditioner × the first ratio = 60 × (1 / 3) = 20 cm; the upper limit value of the condensed water level in the pipe connecting device to the level of 60 cm of the condensed water generated by the air conditioner is the second ratio 4 / 5. Therefore, the upper limit value of the condensed water level in the pipe connecting device = the level of the condensed water generated by the air conditioner × the second ratio = 60 × (4 / 5) = 48 cm.

[0035] Step S102: obtaining, by means of a water level meter, an actual value of the condensed water level in the pipe communication device after the air conditioner has been running for a first preset time.

[0036] In this embodiment, the water level meter can be any type of water level meter that obtains the liquid level value in the device in any manner, such as a tracking water level meter, a pressure sensing water level meter, etc., and the present invention does not impose any limitation on this.

[0037] In one embodiment, a tracking water level meter can be used to obtain the actual value of the condensate level within the pipe connection device after the air conditioner has operated for the first predetermined period of time. Specifically, the tracking water level meter utilizes an electric probe on the weight of the tracking water level meter to contact the water surface, generating an electrical signal that causes the motor of the tracking water level meter to rotate forward or reverse, constantly tracking the position of the water surface point, thereby determining the actual value of the condensate level within the connection device. As this acquisition method is already publicly available, it will not be described in detail here.

[0038] Step S103: Determine whether the actual value is greater than or equal to the lower limit and less than or equal to the upper limit. If so, execute step S104; if not, execute step S105.

[0039] Step S104: The air conditioner drain pipe is not blocked.

[0040] Step S105: The air conditioner drain pipe is clogged.

[0041] Based on the above steps S101 to S105, a water level meter for detecting the condensate level in the cavity of the pipe connecting device that can accommodate condensate is set. After the air conditioner is started, the actual value of the condensate level in the pipe connecting device after the air conditioner has been running for the first preset time can be accurately and timely obtained through the water level meter, thereby improving the accuracy and timeliness of obtaining the actual value of the condensate level in the pipe connecting device; further, by predicting the upper and lower limit values of the condensate level in the pipe connecting device after the first preset time according to the operating mode of the air conditioner, the actual value, upper and lower limit values of the condensate level are compared. If the actual value is between the lower limit and the upper limit, it is determined that the air conditioner drain pipe is not blocked, otherwise it is determined that the air conditioner drain pipe is blocked, which significantly increases the accuracy of judging the blockage of the drain pipe, effectively avoids the problem of air conditioning leakage caused by drain pipe blockage during operation, extends the service life of the air conditioner, further reduces the user's maintenance cost, and improves the user's usage experience.

[0042] See attached Figure 2 , Figure 2 The figure is a flow chart of the main steps of a method for detecting blockage of an air conditioner drain pipe according to another embodiment of the present invention. The air conditioner drain pipe includes an indoor drain pipe and an outdoor drain pipe. The indoor drain pipe and the outdoor drain pipe are connected by a pipe connecting device. The pipe connecting device includes a cavity for accommodating condensed water and a water level meter for detecting the condensed water level in the cavity. The condensed water generated during the operation of the air conditioner is discharged in sequence through the indoor drain pipe, the pipe connecting device, and the outdoor drain pipe. Figure 2 As shown, the method for detecting blockage of an air-conditioning drain pipe in an embodiment of the present invention mainly includes the following steps S201 to S210.

[0043] Step S201: After the air conditioner is started, the temperature change and humidity change in the room where the air conditioner is located after running for a first preset time are predicted according to the operating mode of the air conditioner.

[0044] In this embodiment, the first preset duration is a pre-set duration for predicting the temperature change and humidity change in the room where the air conditioner is located, or it can be a duration determined based on actual demand conditions for predicting the temperature change and humidity change in the room where the air conditioner is located. The embodiment of the present invention does not limit this.

[0045] The temperature change refers to the difference between the ambient temperature in the room where the air conditioner is located before the first preset time period and the ambient temperature in the room where the air conditioner is located after the first preset time period.

[0046] The humidity change refers to the difference between the ambient humidity in the room where the air conditioner is located before the first preset time period and the ambient humidity in the room where the air conditioner is located after the first preset time period.

[0047] The operating modes of the air conditioner may include, but are not limited to, cooling mode, heating mode, dehumidification mode, and ventilation mode.

[0048] In one embodiment, after the air conditioner is started, the air conditioner's operating mode and the first ambient temperature of the room where the air conditioner is located are obtained, and a second ambient temperature of the room where the air conditioner is located is predicted after the air conditioner has been running for a first period of time, with the difference between the first and second ambient temperatures being used as the predicted temperature change. Furthermore, the air conditioner's operating mode and the first ambient humidity of the room where the air conditioner is located are obtained, and a second ambient humidity of the room where the air conditioner is located is predicted after the air conditioner has been running for the first period of time, with the difference between the first and second ambient humidity being used as the predicted humidity change. For example, if the first preset time period is set to 20 minutes, and the air conditioner is started, the operating mode is obtained to be cooling mode, and the first ambient temperature and humidity of the room where the air conditioner is located are 30°C and 25%, then the predicted second ambient temperature and humidity of the room where the air conditioner is located after 20 minutes of operation are 25°C and 28%, respectively. Therefore, the temperature change of the room where the air conditioner is located after 20 minutes of operation = 30°C - 25°C = 5°C, and the humidity change = |25% - 28%| = 3%.

[0049] Step S202: matching the experimental value of the amount of condensed water corresponding to both the temperature change and the humidity change.

[0050] In this embodiment, a correspondence table of different temperature changes and humidity changes and condensed water volume experimental values can be pre-stored, and the corresponding condensed water volume experimental value can be determined according to the temperature change and humidity change predicted in step S210 based on the correspondence table.

[0051] The experimental value of condensed water volume refers to the experimental value of the amount of condensed water generated when the air conditioner is operated under different temperature and humidity changes. The experimental value of condensed water volume is obtained by those skilled in the art based on experimental data.

[0052] Specifically, different temperature variations and humidity-temperature variations can be combined to form multiple sub-combinations. The air conditioner is operated under the environmental conditions of each sub-combination. After the air conditioner has been operated for a first preset period of time, the experimental value of the amount of condensed water generated by the air conditioner is recorded. For each temperature variation and humidity-temperature variation, the average of the experimental values of the amount of condensed water generated by all the air conditioners is used as the experimental value of the amount of condensed water corresponding to both the temperature variation and the humidity-temperature variation. Assuming the temperature variation is 0°C-2°C and the humidity variation is 30%-32%, the temperature variation and humidity variation are combined to form the following nine sub-combinations:

[0053] {0℃, 30%}, {0℃, 31%}, {0℃, 32%}, {1℃, 30%}, {1℃, 31%}, {1℃, 32%}, {2℃, 30%}, {2℃, 31%}, {2℃, 32%};

[0054] Then, after the air conditioner is operated for the first preset period of time under the conditions of the nine sub-combinations, the actual value of the condensation water level generated by the air conditioner is obtained. If the experimental values of the liquid levels of the condensation water generated by the nine sub-combinations are 60cm, 61cm, 62cm, 64cm, 68cm, 70cm, 77cm, 82cm, and 99cm, respectively, the average value of the actual values of the liquid levels of the condensation water of the nine sub-combinations is obtained as the experimental value of the liquid level of the condensation water corresponding to the temperature change of 0℃-2℃ and the humidity temperature change of 30%-32%, that is, the experimental value of the liquid level of the condensation water = (60cm+61cm+62cm+64cm+68cm+70cm+77cm+82cm+99cm)÷9=71.44cm, wherein the experimental value of the liquid level of the condensation water is retained with at least two decimal places.

[0055] Furthermore, according to the above experimental process, the corresponding relationship table of different temperature changes and humidity changes and the experimental values of the condensed water level is obtained as shown in the following table:

[0056]

[0057]

[0058] Step S203: using the matched experimental value of the condensed water volume as the predicted condensed water volume generated by the air conditioner after running for the first preset time period.

[0059] Step S204: determining the liquid level value when the amount of condensed water reaches four fifths of the volume of the cavity containing condensed water in the pipeline communication device as the upper limit value of the condensed water level.

[0060] In this embodiment, the ratio of the upper limit of the condensed water level to the experimental value of the condensed water volume is four-fifths, and the upper limit of the condensed water level is the product of the experimental value of the condensed water volume and four-fifths. Assuming that the experimental value of the condensed water volume level is 120cm, then the upper limit of the condensed water level is

[0061] Step S205: determining the liquid level value when the amount of condensed water reaches one third of the volume of the cavity containing condensed water in the pipeline communication device as the lower limit value of the condensed water level.

[0062] In this embodiment, the ratio of the lower limit of the condensed water level to the experimental value of the condensed water volume is one third, and the upper limit of the condensed water level is the product of the experimental value of the condensed water volume and one third. Assuming that the experimental value of the condensed water volume level is 120cm, then the condensed water level

[0063] Step S206: obtaining, by means of a water level meter, an actual value of the condensed water level in the pipe communication device after the air conditioner has run for the first preset time period.

[0064] In this embodiment, the method of obtaining the actual value of the condensate level in the pipe connecting device after the air conditioner runs for the first preset time by using the water level meter is the same as the method of obtaining in the above step S102, and will not be repeated here.

[0065] Step S207: Determine whether the actual value is less than the lower limit or whether the actual value is greater than the upper limit. If so, execute step S208; if not, execute step S210.

[0066] Step S208: Determine that the air conditioner drain pipe is clogged.

[0067] In this embodiment, if the actual value is less than the lower limit value, it is considered that the condensed water in the indoor drain pipe cannot flow into the pipe connecting device and then flow through the outdoor drain pipe for drainage. Therefore, it is determined that the indoor drain pipe of the air conditioner is blocked; if the actual value is greater than the upper limit value, it is considered that the condensed water in the pipe connecting device cannot be discharged outdoors through the outdoor drain pipe. Therefore, it is determined that the outdoor drain pipe of the air conditioner is blocked.

[0068] Step S209: outputting warning information through the human-computer interaction device of the air conditioner and / or sending warning information to a mobile device connected to the air conditioner for communication.

[0069] In this embodiment, the human-computer interaction device may include a display screen for outputting a warning message indicating that the air conditioner drain pipe is clogged, a touch screen integrated with a function for outputting a warning message indicating that the air conditioner drain pipe is clogged, or an alarm, such as a buzzer, for outputting a warning message indicating that the air conditioner drain pipe is clogged. This embodiment of the present invention is not limited to this.

[0070] Mobile devices include but are not limited to mobile phones, tablets, laptops, smart bracelets and smart watches, etc.

[0071] Step S210: Determine that the air conditioner drain pipe is not blocked.

[0072] In this embodiment, if the actual value is between the lower limit and the upper limit, it is considered that the condensed water in the indoor drain pipe can flow normally into the pipe connecting device and then flow through the outdoor drain pipe to be discharged outdoors. Therefore, it is determined that both the indoor and outdoor drain pipes of the air conditioner are not blocked.

[0073] It should be pointed out that although the various steps in the above embodiments are described in a specific order, those skilled in the art will understand that in order to achieve the effects of the present invention, different steps do not have to be performed in such an order. They can be performed simultaneously (in parallel) or in other orders. These changes are within the scope of protection of the present invention.

[0074] Furthermore, the present invention also provides a blockage detection device for an air-conditioning drain pipe.
