Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a top-outlet air conditioner, and a monitoring device, method, and storage medium for an outdoor exhaust device thereof. Background Art

[0002] When the top-outlet air conditioner outdoor unit is installed on the equipment floor, in order not to affect 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 the air duct, or the air duct itself is damaged and leaks, it is easy to cause mechanical damage to the high-speed rotating fan or affect the working condition of the exhaust fan. Therefore, it is necessary to monitor the abnormality of the exhaust device.

[0003] In order to implement effective monitoring of the exhaust device, the relevant technology discloses a method for monitoring abnormalities in the exhaust duct, which includes: setting a wind pressure sensor or a negative pressure sensor at the air outlet, when the wind pressure monitoring data is outside the preset range, adjusting the speed of the fan and sending a fault signal to the management terminal to prompt maintenance; or stabilizing the air volume at the air inlet through the air volume control valve.

[0041] In order to be able to understand the features and technical contents of the embodiments of the present disclosure in more detail, the implementation of the embodiments of the present disclosure is described in detail below in conjunction with the accompanying drawings. The attached drawings are for reference only and are not used to limit the embodiments of the present disclosure. In the following technical description, for the convenience of explanation, a full understanding of the disclosed embodiments is provided through multiple details. However, one or more embodiments can still be implemented without these details. In other cases, to simplify the drawings, well-known structures and devices can be simplified for display.

[0042] The terms "first", "second", etc. in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged where appropriate, so that the embodiments of the embodiments of the present disclosure described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0043] Unless otherwise stated, the term "plurality" means two or more.

[0044] In the embodiment of the present disclosure, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B indicates: A or B.

[0045] The term "and / or" is a description of the association relationship 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" may refer to an association relationship or a binding relationship. The correspondence between A and B means that there is an association relationship or a binding relationship between A and B.

[0047] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0048] The air conditioner outdoor unit usually includes a compressor, a condenser, a fan and an electronic control device, wherein the electronic control device includes a processor, which is used to control the compressor, condenser, exhaust fan and other electronic control components to achieve various functions of the air conditioner outdoor unit. The main difference between the top-outlet air conditioner outdoor unit and the general air conditioner outdoor unit is that the exhaust fan and the air outlet direction are upward, and a protective net is usually laid on the top side of the exhaust fan.

[0049] When the top-outlet air conditioner outdoor unit is connected to the exhaust duct through an air duct, the protective net on the top side of the exhaust fan is usually removed to improve the heat dissipation efficiency of the fan. When the exhaust device cracks or when small organisms or solid foreign objects enter the exhaust device during long-term use, it will cause mechanical damage to the working exhaust fan. Therefore, it is necessary to monitor foreign objects in the exhaust device of the top-outlet air conditioner outdoor unit. In the related art, wind pressure sensors or negative pressure sensors are usually used to monitor the working conditions of the exhaust fan and adjust the speed of the exhaust fan by controlling the speed of the exhaust fan. However, the related art does not take into account the hazards caused by small organisms or solid foreign objects entering the exhaust device, and it is impossible to monitor foreign objects entering the exhaust duct.

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

[0051] Figure 1 It is a structural schematic diagram of a monitoring device for an exhaust device of an outdoor unit of a top-outlet air conditioner provided by an embodiment of the present disclosure;

[0052] Figure 2 It is a connection diagram of a monitoring device for an exhaust device of an outdoor unit of a top-outlet air conditioner provided in an embodiment of the present disclosure.

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

[0054] The monitoring device for the exhaust device of the top-outlet air conditioner outdoor unit includes an infrared detection module 180 and an electronic control processing module 190. The infrared detection module 180 is arranged inside the air duct 120 and / or the exhaust duct 130, and is used to transmit and receive infrared signals; the electronic control processing module 190 is arranged in the air conditioner outdoor unit 110 and is electrically connected to the infrared detection module 180, and is used to determine the abnormal response instruction for the exhaust device according to the signal data of the infrared detection module 190.

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

[0056] Optionally, the infrared detection module 180 is disposed inside the air duct 120 to achieve 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 in the air duct 120 at one end close to 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 air conditioner outdoor unit 110 is a first preset value D1; the second infrared detection module 160 is disposed in the air duct 120 at one end close to 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 air conditioner 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 arranged in the air duct 120 along the flow direction of the exhaust air path. It 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 monitor the abnormal situation 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 disposed inside the exhaust duct 130 to implement safety monitoring of the exhaust duct 130 .

[0061] Furthermore, the infrared detection module 180 also includes a third infrared detection module 170, which is disposed in the exhaust duct 130 at one end near the air inlet of the exhaust duct 130. It can be determined whether there are foreign objects passing through the air inlet of the exhaust duct 130, the air inlet of the air duct 120, and the air outlet of the air duct 120, and the abnormal conditions of the exhaust device can be monitored more comprehensively.

[0062] In this way, by setting up multiple infrared detection modules 180, multi-point monitoring of the exhaust device is realized, and a multi-layer monitoring mechanism is realized, which can further improve the reliability of detecting foreign objects such as small organisms or solids that have little effect on wind pressure entering the exhaust device, thereby reducing the occurrence of equipment failures caused by foreign objects entering the exhaust device.

[0063] The infrared detection module 180 in the disclosed embodiment is an active alarm, which is not subject to false alarms due to abnormal temperature changes. Because the air conditioner is used for cooling or heating, the temperature of the air duct changes greatly, which avoids the situation where the passive infrared detection module is easily affected by the temperature and causes false touches. The infrared detection module 180 includes a transmitter and a receiver. The transmitter transmits infrared rays, and the receiver receives infrared rays accordingly, and detects the infrared signal radiation value through the built-in sensor probe.

[0064] Optionally, the infrared signal transmitting direction and receiving direction 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 the exhaust duct 130.

[0066] Figure 3 A monitoring method for an exhaust device of an outdoor unit of a top-outlet air conditioner provided in an embodiment of the present disclosure is applied to the above-mentioned monitoring device for an exhaust device of an outdoor unit of a top-outlet air conditioner. The method can be executed in an air conditioner processor, in an outdoor unit of a top-outlet air conditioner, or by an electronic control processing module of a monitoring device. In the embodiment of the present disclosure, the solution is described with the processor as the execution subject.

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

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

[0069] The signal data of the infrared detection module includes one or more of the signal sending data, signal receiving data, signal sending time, and signal receiving time of the infrared detection module.

[0070] Step S302: When the signal data meets the trigger condition, the processor determines the abnormal response instruction corresponding to the exhaust device according to the properties of the infrared detection module.

[0071] The trigger condition refers to a situation in which the acquired signal data indicates an abnormal event that a foreign object may enter the exhaust device.

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

[0073] Step S303: the processor executes the exception handling instruction.

[0074] Abnormal response instructions refer to the processing actions that can be taken to reduce the possibility of failure of components inside the exhaust device when an abnormal event occurs in the exhaust device.

[0075] Optionally, the abnormal response instructions include reducing the exhaust fan speed, sound and light alarms, pushing prompt information to the user, etc.

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

[0077] Among them, F1>F, when the infrared detection unit detects foreign matter, increasing the acquisition frequency can monitor the foreign matter situation in real time, and the default low frequency can save energy and extend the life of the device.

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

[0079] In this way, by adopting the monitoring method for the exhaust device of the outdoor unit of the top-air air-discharging air conditioner provided in the embodiment of the present disclosure, abnormal conditions in the exhaust duct and the air guide duct can be detected, and foreign objects such as small organisms or solids that have little effect on the wind pressure entering the exhaust device can be detected. By executing corresponding abnormal response instructions, the exhaust device can be adjusted to avoid mechanical damage to the blades of the exhaust fan in operation caused by foreign objects entering the exhaust device, thereby reducing the possibility of deterioration of the operating condition of the outdoor unit of the air conditioner.

[0080] The following describes how to determine an abnormal response instruction when the infrared detection modules include multiple ones and the multi-point signal data meet the triggering conditions.

[0081] Figure 4 Another monitoring method for an exhaust device of an outdoor unit of a top-outlet air conditioner provided in an embodiment of the present disclosure is applied to the monitoring device for an exhaust device of an outdoor unit of a top-outlet air conditioner. In an embodiment of the present disclosure, a processor is used as an execution subject to illustrate the solution.

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

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

[0084] Step S402: When the signal data meets the trigger condition, the processor obtains the property of the infrared detection module whose signal data meets the trigger condition to determine the corresponding exception processing priority.

[0085] Step S403: The processor determines the abnormality handling instruction corresponding to the exhaust device according to the abnormality handling priority.

[0086] Step S404: the processor executes the exception handling instruction.

[0087] Exception handling priority refers to the processing priority when multiple abnormal events occur. In the case of multiple abnormalities, the abnormal response instructions corresponding to the infrared detection module with a higher exception 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 warning intensity of the abnormal response instruction refers to the different execution strengths when performing the same action. For example, when the abnormal response instruction is to reduce the exhaust fan speed, the warning intensity of reducing the exhaust fan speed to 0 is the highest; when the speed N1 is greater than the speed N2, the warning intensity of reducing the exhaust fan speed by N1 is higher than that of reducing the exhaust fan speed by N2.

[0090] Furthermore, the determination of the exception handling priority can be determined by setting the position in the infrared detection module properties. The setting position of the infrared detection module can be stored in the processor and sent together when receiving the signal data of the infrared detection module.

[0091] For example, when the attribute of the infrared detection module includes the setting position of the infrared detection module, the determination of the exception handling priority includes:

[0092] The setting position of the infrared detection module whose signal data meets the trigger condition is obtained; and the current exception handling priority is determined according to the corresponding relationship between the setting position and the exception handling priority.

[0093] Among them, the correspondence between the setting position and the exception handling priority can be stored in the database in the form of a one-to-one correspondence data table. After obtaining the setting position of the infrared detection module whose current signal data meets the trigger condition, the current exception handling priority can be determined by querying the database.

[0094] Here, the correspondence between the setting position and the exception handling priority includes:

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

[0096] The abnormality priority of the infrared detection module in which the distance between the air duct and the axis of the exhaust fan is close is higher than the abnormality priority of the infrared detection module in which the distance between the air duct and the axis of the exhaust fan is far.

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

[0098] The distance between the infrared detection module and the axis of the exhaust fan is obtained when the signal data meets the trigger condition;

[0099] Determine the exception handling priority among multiple infrared detection modules according to the distance between the infrared detection module and the axis of the exhaust fan;

[0100] The smaller the distance between the infrared detection module and the exhaust fan axis, the higher the abnormality handling priority of the infrared detection module. The closer the infrared detection module is to the exhaust fan axis, the greater the probability that the triggered foreign matter will cause mechanical damage to the exhaust fan.

[0101] The following describes how to determine whether the signal data meets the trigger condition.

[0102] Figure 5 Another monitoring method for an exhaust device of an outdoor unit of a top-outlet air conditioner provided in an embodiment of the present disclosure is applied to the monitoring device for an exhaust device of an outdoor unit of a top-outlet air conditioner. In an embodiment of the present disclosure, a processor is used as an execution subject to illustrate the solution.

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

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

[0105] Step S502: within a set time after the infrared detection module transmits an infrared signal, when |Rn-Ra|>Rx is satisfied, the signal data meets the trigger condition, where Rn is the infrared signal radiation threshold; Ra is the infrared signal radiation value received in real time; and Rx is the radiation trigger value.

[0106] Step S503, determining the abnormal response instruction corresponding to the exhaust device according to the properties of the infrared detection module.

[0107] Step S504: the processor executes the exception handling instruction.

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

[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 incurs normal energy loss during transmission in the pipeline under normal conditions.

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

[0111] Rn-Ra>Rx, that is, the difference between the received infrared signal radiation value and the infrared signal radiation threshold is greater than the radiation trigger value. At this time, there may be foreign matter in the pipeline that causes multiple infrared signals emitted by the infrared detection module to be refracted or rebounded, and the received infrared signal radiation value is greater than the infrared signal radiation threshold.

[0112] Rn-Ra<-Rx, that is, 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. At this time, there may be foreign matter in the pipeline that causes the infrared signal radiation value received by the infrared detection module to be interrupted or rebound, and the received value is much smaller than the normal value.

[0113] When the signal data does not meet the trigger conditions, if the probe detects that the infrared ray is stationary, that is, the infrared ray emitted by the generator is not disconnected and does not rebound, it is determined that there is no foreign body movement and it is normal.

[0114] When the signal data meets the trigger conditions, it means that if a small animal or person enters the monitoring range, the emitted infrared signal will be disconnected or rebounded, causing the continuous static state of the infrared light to change. The receiver will judge whether a foreign object has entered and send the signal data to the processor. When the processor determines that the trigger conditions are met, it executes the corresponding exception response instructions.

[0115] In practical applications, when the monitoring device for the exhaust device of the top-outlet air conditioner outdoor unit includes the first infrared detection module, the second infrared detection module, and the third infrared detection module, as shown in FIG. Figure 6As shown, the monitoring method for the exhaust device of the top-outlet air conditioner outdoor unit includes:

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

[0117] Step S602: when the signal data meets the trigger condition, obtain the property of the infrared detection module whose signal data meets the trigger condition.

[0118] Step S603: When the infrared detection modules that meet the triggering condition include the first infrared detection module, determine that the abnormal response instruction corresponding to the exhaust device is the first instruction.

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

[0120] Step S605: when the infrared detection module that meets the trigger condition is the third infrared detection module, determine that the abnormal response instruction corresponding to the exhaust device is the third instruction, wherein the warning intensity of the second instruction is greater than the warning intensity of the third instruction.

[0121] Step S606, executing corresponding abnormality handling instructions.

[0122] Here, the first instruction includes stopping the exhaust fan and a warning reminder. The second instruction includes reducing the exhaust fan speed and a warning reminder. The third instruction includes sound and light alarms for driving away. The warning reminder refers to pushing warning reminder information to after-sales personnel or users through SMS terminals or software terminals.
