Description

Technical Field

[0001] This application relates to the field of smart home appliance technology, such as a top-discharge air conditioner, a monitoring device, method, and storage medium for its outdoor unit exhaust device. Background Technology

[0002] When the outdoor unit of a top-discharge air conditioner is installed on the equipment floor, in order to avoid affecting the performance of the equipment and improve the exhaust effect, the exhaust device is usually connected to the exhaust duct and the protective net of the outdoor unit itself is removed. When foreign objects enter the exhaust duct and ductwork, or when the ductwork itself is damaged or leaks air, the high-speed rotating fan can easily suffer mechanical damage or affect the operation of the exhaust fan. Therefore, abnormal monitoring of the exhaust device is essential.

[0003] To effectively monitor exhaust systems, a method for monitoring exhaust duct anomalies has been disclosed, comprising: installing a wind pressure sensor or a negative pressure sensor at the air outlet; adjusting the speed of the fan and sending a fault signal to the management terminal to prompt for maintenance when the wind pressure monitoring data is outside a preset range; or stabilizing the airflow at the air inlet through an airflow control valve.

[0004] In implementing the embodiments of this disclosure, at least the following problems were found in the related technology: the related technology monitors the exhaust situation using wind pressure sensors. However, when small organisms or solid objects with minimal impact on wind pressure enter the duct, the wind pressure sensor cannot detect or issue an alarm. Once such objects enter the vertical air duct, they may collide with the high-speed rotating fan blades and cause damage.

[0041] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0045] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0046] The term "correspondence" can refer to an association or binding relationship. The correspondence between A and B means that there is an association or binding relationship between A and B.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0048] An air conditioner outdoor unit typically includes a compressor, condenser, fan, and electronic control unit. The electronic control unit includes a processor, which controls the compressor, condenser, exhaust fan, and other electronic components to achieve the various functions of the outdoor unit. The main difference between a top-discharge air conditioner outdoor unit and a regular air conditioner outdoor unit is that the exhaust fan and airflow direction are upwards, and a protective mesh is usually installed on the top side of the exhaust fan.

[0049] When the outdoor unit of a top-discharge air conditioner is connected to the exhaust duct via a duct, the protective mesh on the top side of the exhaust fan is usually removed to improve the fan's heat dissipation efficiency. However, if the exhaust system cracks or small organisms or solid foreign objects enter the exhaust system during prolonged use, it can cause mechanical damage to the operating exhaust fan. Therefore, monitoring for foreign objects in the exhaust system of a top-discharge air conditioner outdoor unit is essential. Current technologies typically use wind pressure sensors or negative pressure sensors to monitor the exhaust fan's operating condition and adjust its speed accordingly. However, these technologies do not consider the hazards caused by small organisms or solid foreign objects entering the exhaust system and cannot effectively monitor foreign objects entering the exhaust duct.

[0050] This disclosure provides a monitoring device for the exhaust system of a top-discharge air conditioner outdoor unit, so as to detect foreign objects in the exhaust system of the top-discharge air conditioner outdoor unit.

[0051] Figure 1 This is a schematic diagram of the structure of a monitoring device for the exhaust system of a top-discharge air conditioner outdoor unit provided in an embodiment of this disclosure;

[0052] Figure 2 This is a connection diagram of a monitoring device for the exhaust system of a top-discharge air conditioner outdoor unit provided in an embodiment of this disclosure.

[0053] like Figure 1 ,2 As shown, the top-discharge air conditioner outdoor unit 110 includes a vertically arranged air guide duct 120 and a horizontally arranged exhaust duct 130; the air inlet of the air guide duct 120 is connected to the air outlet at the top of the air conditioner outdoor unit 110, and the air outlet of the air guide duct 120 is connected to the air inlet of the exhaust duct 130.

[0054] The monitoring device for the exhaust system of a top-discharge air conditioner outdoor unit includes an infrared detection module 180 and an electronic control processing module 190. The infrared detection module 180 is located inside the air duct 120 and / or exhaust duct 130, and is used to emit and receive infrared signals. The electronic control processing module 190 is located in the air conditioner outdoor unit 110 and is electrically connected to the infrared detection module 180, and is used to determine abnormal response commands for the exhaust system based on the signal data from the infrared detection module 190.

[0055] In this embodiment, the infrared detection module 180 can detect small organisms or solid foreign objects entering the exhaust duct 130 and the air guide duct 120. The electronic control processing module 190 can determine the corresponding abnormal response command by judging the infrared signal data, thereby realizing the monitoring of small organisms or solid foreign objects and avoiding damage to the fan blades of the exhaust fan 140 and deterioration of the outdoor unit's operating conditions.

[0056] Optionally, the infrared detection module 180 is disposed inside the air duct 120 for safety monitoring of the air duct 120.

[0057] Furthermore, the infrared detection module 180 includes a first infrared detection module 150 and a second infrared detection module 160. The first infrared detection module 150 is disposed inside the air duct 120 near the air inlet of the air duct 120; the distance between the first infrared detection module 150 and the axis of the exhaust fan 140 of the outdoor unit 110 is a first preset value D1; the second infrared detection module 160 is disposed inside the air duct 120 near the air outlet of the air duct 120; the distance between the second infrared detection module 160 and the axis of the exhaust fan 140 of the outdoor unit 110 is a second preset value D2; D2 > D1.

[0058] That is, the first infrared detection module 150 and the second infrared detection module 160 are installed inside the air duct 120 along the airflow direction of the exhaust path. They can determine whether there are foreign objects passing through the air inlet of the air duct 120 and the air inlet of the exhaust duct 130, and can monitor the abnormal conditions of the entire exhaust device.

[0059] Optionally, the value range of D1 is [50, 70] mm, more specifically, D1 = 60 mm; the value range of D2 is [250, 350] mm, more specifically, D2 = 300 mm.

[0060] Optionally, the infrared detection module 180 is installed inside the exhaust duct 130 to enable safety monitoring of the exhaust duct 130.

[0061] Furthermore, the infrared detection module 180 also includes a third infrared detection module 170, which is located inside the exhaust duct 130 near the air inlet of the exhaust duct 130. It can determine whether there are foreign objects passing through the air inlet of the exhaust duct 130, the air inlet of the duct 120, and the air outlet of the duct 120, and can more comprehensively monitor abnormal conditions of the exhaust device.

[0062] Thus, by setting up multiple infrared detection modules 180, multi-point monitoring of the exhaust system can be achieved, realizing a multi-layer monitoring mechanism. This further improves the reliability of detecting foreign objects that have little impact on air pressure, such as small organisms or solid objects, entering the exhaust system. This reduces the occurrence of equipment malfunctions caused by foreign objects entering the exhaust system.

[0063] The infrared detection module 180 in this embodiment is an active alarm, unaffected by abnormal temperature changes that could trigger a false alarm. Because air conditioning involves cooling or heating, causing significant temperature changes in the air duct, this avoids the false alarms that can occur with passive infrared detection modules, which are easily affected by temperature fluctuations. The infrared detection module 180 includes a transmitter and a receiver. The transmitter emits infrared light, and the receiver receives it, detecting the infrared signal radiation value using a built-in sensing probe.

[0064] Optionally, the infrared signal transmission and reception directions of the infrared detection module 180 are both perpendicular to the exhaust direction of the exhaust device.

[0065] In this way, by transmitting and receiving signals perpendicular to the exhaust direction, it is possible to detect whether there are foreign objects passing through the air duct 120 and exhaust duct 130.

[0066] Figure 3 This disclosure provides a monitoring method for the exhaust device of a top-discharge air conditioner outdoor unit, applicable to the aforementioned monitoring device for the exhaust device of a top-discharge air conditioner outdoor unit. It can be executed in the air conditioner processor, in the top-discharge air conditioner outdoor unit, or by the electronic control processing module of the monitoring device. In this disclosure, the solution is described with the processor as the execution entity.

[0067] Combination Figure 3 As shown, the monitoring method for the exhaust device of the outdoor unit of a top-discharge air conditioner includes:

[0068] Step S301: The processor acquires the signal data from the infrared detection module.

[0069] The signal data of the infrared detection module includes one or more of the following: signal transmission data, signal reception data, signal transmission time, and signal reception time.

[0070] In step S302, if the signal data meets the triggering conditions, the processor determines the corresponding abnormal response command for the exhaust device based on the attributes of the infrared detection module.

[0071] The triggering condition refers to the situation where the acquired signal data indicates an abnormal event that may occur, such as the entry of foreign objects into the exhaust system.

[0072] The attributes of the infrared detection module are used to indicate the abnormal event situation corresponding to the location detected by the infrared detection module.

[0073] In step S303, the processor executes an exception handling instruction.

[0074] Anomaly response instructions refer to the actions that can be taken to reduce the possibility of component failure when an abnormal event occurs in the exhaust system.

[0075] Optionally, abnormal response instructions include reducing the exhaust fan speed, triggering audible and visual alarms, and sending notification messages to the user.

[0076] Optionally, acquiring signal data from the infrared detection module includes: acquiring signal data from the infrared detection module at frequency F; and acquiring signal data from the infrared detection module at frequency F1 within a set time period after executing the abnormal response command.

[0077] Where F1>F, when the infrared detection unit detects a foreign object, increasing the acquisition frequency can enable real-time monitoring of the foreign object situation, and the default low frequency can save energy and extend the device life.

[0078] Optionally, the value of F is in the range of [0.5, 1.5] times / second, more specifically, F = 1 time / second; the value of F1 is in the range of [2, 4] times / second, more specifically, F = 3 times / second.

[0079] Thus, the monitoring method for the exhaust device of the top-discharge air conditioner outdoor unit provided in this embodiment can detect abnormalities in the exhaust duct and air guide pipe, detect foreign objects that have little impact on air pressure, such as small organisms or solids, and adjust the exhaust device by executing corresponding abnormal response commands. This can prevent foreign objects entering the exhaust device from causing mechanical damage to the fan blades of the operating exhaust fan and reduce the possibility of deterioration of the operating condition of the air conditioner outdoor unit.

[0080] The following explains how to determine the abnormal response instruction when multiple infrared detection modules are involved and the signal data from multiple points meet the triggering conditions.

[0081] Figure 4 This disclosure provides another monitoring method for the exhaust device of a top-discharge air conditioner outdoor unit, applied to the aforementioned monitoring device for the exhaust device of a top-discharge air conditioner outdoor unit. In this disclosure, the solution is described using a processor as the execution entity.

[0082] Combination Figure 4 As shown, the monitoring method for the exhaust device of the outdoor unit of a top-discharge air conditioner includes:

[0083] Step S401: The processor acquires the signal data from the infrared detection module.

[0084] In step S402, if the signal data meets the triggering conditions, the processor obtains the attributes of the infrared detection module whose signal data meets the triggering conditions in order to determine the corresponding exception handling priority.

[0085] In step S403, the processor determines the corresponding exception response instruction for the exhaust device based on the exception handling priority.

[0086] In step S404, the processor executes exception handling instructions.

[0087] Anomaly handling priority refers to the processing priority when multiple anomalies occur. In the case of multiple anomalies, the anomaly response instructions corresponding to the infrared detection module with higher anomaly handling priority will be executed first.

[0088] Optionally, the higher the exception handling priority, the higher the warning intensity of the corresponding exception response instruction.

[0089] The alert intensity of an anomaly response command refers to the different levels of enforcement when performing the same action. For example, when the anomaly response command is to reduce the exhaust fan speed, the alert intensity is highest when the exhaust fan speed is reduced to 0; when the rotation speed N1 is greater than the rotation speed N2, the alert intensity is higher when the exhaust fan speed is reduced by N1 than when the exhaust fan speed is reduced by N2.

[0090] Furthermore, the priority of exception handling can be determined by setting the location in the infrared detection module's properties. This location setting can be stored in the processor and sent along with the signal data received from the infrared detection module.

[0091] For example, when the properties of the infrared detection module include the setting location of the infrared detection module, the determination of the exception handling priority includes:

[0092] The system acquires the setting position of the infrared detection module that meets the triggering conditions based on the signal data; and determines the current exception handling priority based on the correspondence between the setting position and the exception handling priority.

[0093] The correspondence between the setting location and the priority of abnormal handling can be stored in the database in the form of a one-to-one correspondence data table. After obtaining the setting location of the infrared detection module that meets the triggering conditions for the current signal data, the current priority of abnormal handling can be determined by querying the database.

[0094] Here, the correspondence between the location and the priority of exception handling is set as follows:

[0095] The abnormality priority of the infrared detection module in the exhaust duct is higher than that of the infrared detection module in the air duct.

[0096] The infrared detection module that is closer to the exhaust fan shaft inside the air duct has a higher anomaly priority than the infrared detection module that is farther away from the exhaust fan shaft inside the air duct.

[0097] For example, when the properties of the infrared detection module include the distance between the infrared detection module and the exhaust fan shaft, the determination of the exception handling priority includes:

[0098] Acquire signal data to determine the distance between the infrared detection module and the exhaust fan shaft that meets the triggering conditions;

[0099] The priority of anomaly handling among multiple infrared detection modules is determined based on the distance between the infrared detection module and the exhaust fan shaft.

[0100] The closer the infrared detection module is to the exhaust fan shaft, the higher the priority of its anomaly handling. The closer the infrared detection module is to the exhaust fan shaft, the greater the probability that the triggered foreign object will cause mechanical damage to the exhaust fan.

[0101] The following explains how to determine if signal data meets the triggering conditions.

[0102] Figure 5 This disclosure provides another monitoring method for the exhaust device of a top-discharge air conditioner outdoor unit, applied to the aforementioned monitoring device for the exhaust device of a top-discharge air conditioner outdoor unit. In this disclosure, the solution is described using a processor as the execution entity.

[0103] Combination Figure 5 As shown, the monitoring method for the exhaust device of the outdoor unit of a top-discharge air conditioner includes:

[0104] Step S501: The processor acquires the signal data from the infrared detection module.

[0105] Step S502: Within a set time after the infrared detection module emits an infrared signal, if |Rn-Ra|>Rx, the signal data meets the trigger condition. Here, Rn is the infrared signal radiation threshold; Ra is the real-time received infrared signal radiation value; and Rx is the radiation trigger value.

[0106] Step S503: Determine the corresponding abnormal response command for the exhaust device based on the properties of the infrared detection module.

[0107] In step S504, the processor executes exception handling instructions.

[0108] Here, |Rn-Ra|>Rx includes at least one of the following abnormal conditions.

[0109] The infrared signal radiation threshold Rn refers to the energy value of the infrared signal received after the infrared signal emitted by the infrared detection module has undergone normal energy loss during transmission within the pipeline under normal conditions.

[0110] The radiation trigger value Rx represents the reasonable range of signal radiation energy loss.

[0111] Rn-Ra>Rx, meaning the difference between the received infrared signal radiation value and the infrared signal radiation threshold is greater than the radiation trigger value. In this case, foreign objects in the pipeline may cause multiple infrared signals emitted by the infrared detection module to refract or bounce, resulting in the received infrared signal radiation value exceeding the infrared signal radiation threshold.

[0112] Rn-Ra<-Rx, meaning the received infrared signal radiation value is less than the infrared signal radiation threshold, and the absolute value of the difference between the two is greater than the radiation trigger value. In this case, there may be foreign objects in the pipeline that cause the infrared signal radiation value received by the infrared detection module to be interrupted or bounced, and the received value is much lower than the normal value.

[0113] If the probe detects that the infrared light is stationary when the signal data does not meet the triggering conditions, that is, the infrared light emitted by the generator is continuous and does not bounce, then it is determined that there is no foreign object moving and it is normal.

[0114] When the signal data meets the triggering conditions, it means that if a small animal or person enters the monitoring range, it will cause the emitted infrared signal to disconnect or bounce, resulting in a change in the continuous static state of the infrared light. The receiver will determine that a foreign object has entered and will send signal data to the processor. When the processor determines that the triggering conditions are met, it will execute the corresponding abnormal response instructions.

[0115] In practical applications, when the monitoring device for the exhaust system of a top-discharge air conditioner outdoor unit includes the aforementioned first infrared detection module, second infrared detection module, and third infrared detection module, such as Figure 6As shown, the monitoring method for the exhaust device of the outdoor unit of a top-discharge air conditioner includes:

[0116] Step S601: The processor acquires the signal data from the infrared detection module.

[0117] Step S602: If the signal data meets the triggering conditions, obtain the attributes of the infrared detection module whose signal data meets the triggering conditions.

[0118] Step S603: If the infrared detection module that meets the triggering conditions includes the first infrared detection module, determine that the abnormal response command corresponding to the exhaust device is the first command.

[0119] Step S604: If the infrared detection modules that meet the triggering conditions include a second infrared detection module, determine that the abnormal response command corresponding to the exhaust device is the second command. The warning intensity of the first command is greater than the warning intensity of the second command.

[0120] Step S605: If the infrared detection module that meets the triggering conditions is the third infrared detection module, determine that the abnormal response command corresponding to the exhaust device is the third command. The warning intensity of the second command is greater than that of the third command.

[0121] Step S606: Execute the corresponding exception handling instructions.

[0122] Here, the first instruction includes stopping the exhaust fan and providing a warning. The second instruction includes reducing the exhaust fan speed and providing a warning. The third instruction includes an audible and visual alarm to urge the fan to stop. The warning refers to sending alert messages to after-sales personnel or users via SMS or software.

[0123] Combination Figure 7 As shown, this disclosure provides a monitoring device 710 for the exhaust fan of a top-discharge air conditioner outdoor unit, including a processor 700 and a memory 701. Optionally, the device may further include a communication interface 702 and a bus 703. The processor 700, communication interface 702, and memory 701 can communicate with each other via the bus 703.

[0124] Furthermore, the logic instructions in the aforementioned memory 701 can be implemented as software functional units and, when sold or used as independent products, can be stored in a computer-readable storage medium.
