Description

Technical Field

[0001] This invention relates to the field of air conditioning equipment technology, and in particular to an air conditioning device, its control method, and a storage medium. Background Technology

[0002] Air conditioning equipment is an important tool for improving ambient temperature. When operating in cooling mode, the cool air output by air conditioners easily condenses at the air outlets (the temperature at the outlets is much lower than the dew point temperature of the surrounding air, so water vapor in the air easily cools and condenses into water), dripping onto the ground or objects below the air conditioner, thus affecting the user experience. While technologies exist that use dew point sensors to detect condensation in air conditioners, the air outlets typically experience strong airflow and temperature fluctuations, and the dew point sensors are affected by factors such as airflow speed and temperature at the outlet, potentially leading to false readings. Therefore, current technology suffers from low accuracy in condensation detection for air conditioners.

[0010] The abnormal data acquisition results include: the distance detected by the ranging sensor is less than a preset first distance threshold, or the ranging sensor does not detect any distance.

[0011] In one embodiment, the step of controlling condensation includes:

[0015] In one embodiment, the step of determining whether a human body or obstacle exists below the lower air outlet based on the data acquisition results of the ranging sensor includes:

[0016] If the distance detected by the ranging sensor is greater than a preset first distance threshold and less than a preset second distance threshold, it is determined that there is a human body or obstacle below the lower air outlet.

[0017] In one embodiment, the method includes:

[0018] Receive distance calibration instruction, detect the current distance to the air outlet of the air conditioning device through the distance measuring sensor, and update the preset second distance threshold based on the current distance;

[0019] And / or, periodically detect the current distance to the air outlet of the air conditioning device using the ranging sensor, and update the preset second distance threshold based on the current distance.

[0020] In one embodiment, the step of determining that a portion of the airflow from the lower air outlet of the air conditioning device is directed toward a ranging sensor located at the lower air outlet includes:

[0022] The airflow direction of the preset air duct of the air conditioning device is controlled to be directed toward the ranging sensor.

[0023] In one embodiment, the ranging sensor is a time-of-flight (TOF) sensor, and the surface of the ranging sensor is covered with an infrared filter.

[0024] The present invention also provides a control device for an air conditioning device, wherein a portion of the air outlet of the air conditioning device is directed toward a ranging sensor located at the lower air outlet; the control device for the air conditioning device includes:

[0025] The acquisition module is used to acquire the data collection results of the ranging sensor during the operation of the air conditioning equipment;

[0026] The control module is used to determine whether condensation exists at the lower air outlet based on the data acquisition results of the ranging sensor, and to control the condensation.

[0030] This invention provides a control method that achieves at least the following technical effects: A distance sensor is installed at the lower air outlet of an air conditioning unit, and part of the airflow direction at the lower air outlet is directed towards the distance sensor.

[0039] The objectives, features, and advantages of this invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Cool air from air conditioning units easily condenses at the lower air outlet, dripping onto the ground or objects below, resulting in a poor user experience. However, current dew point sensors (used to detect condensation at the lower air outlet of an air conditioner) are expensive and require precise placement. Furthermore, because the lower air outlet typically experiences strong airflow and temperature fluctuations, the dew point sensor is affected by factors such as airflow speed and temperature, potentially leading to misjudgments. Therefore, dew point sensors are not suitable for placement at the lower air outlet, making it difficult to accurately detect the presence of condensation there.

[0042] Therefore, this embodiment of the invention, by setting a distance sensor at the lower air outlet of the air conditioning device, and by using the data collected by the distance sensor during the operation of the air conditioning device, determines the presence of condensation at the lower air outlet, thereby enabling condensation control, improving the accuracy of condensation detection, facilitating condensation control, and enhancing the user experience.

[0043] To overcome the above-mentioned shortcomings, the present invention provides a control method for an air conditioning device:

[0044] Based on this, the present invention proposes a control method for an air conditioning device in the first embodiment, wherein a portion of the air outlet direction at the lower air outlet of the air conditioning device is directed toward a ranging sensor located at the lower air outlet; please refer to Figure 1 The control method for the air conditioning equipment includes steps S10 to S20:

[0045] Step S10: During the operation of the air conditioning equipment, acquire the data collection results from the ranging sensor;

[0046] It should be noted that a distance sensor is installed at the lower air outlet of the air conditioning unit. When installing the distance sensor at the lower air outlet, it is necessary to ensure that the distance sensor is not obstructed by the air guide vanes of the lower air outlet. In this embodiment, there are no specific restrictions on the location of the distance sensor installed at the lower air outlet.

[0047] When a distance sensor is installed in an air conditioning unit, during operation, the airflow direction of a portion of the lower air outlet needs to be towards the distance sensor to facilitate condensation at the sensor location. This allows the distance sensor to quickly detect whether condensation is present at the lower air outlet. For example, the airflow direction of the adjacent blades near the distance sensor in the lower air outlet can be towards the sensor. There can be one or more adjacent blades; this embodiment does not specifically limit this.

[0048] The data acquisition results are characterized as the data collected by the distance sensor during the operation of the air conditioning equipment. The data acquisition results may include distance data collected by the distance sensor, such as the detected distance to the lower air outlet of the air conditioning equipment. Since the cold air output by the air conditioning equipment is prone to condensation at the lower air outlet, the data acquisition results of the distance sensor can be obtained when the air conditioning equipment is running in cooling mode. When the air conditioning equipment is running in heating mode, the distance sensor can be put into sleep mode to reduce the energy consumption of the air conditioning equipment, or it can continue to acquire data acquisition results. This embodiment does not specifically limit this.

[0049] For example, during the operation of an air conditioning device, a distance sensor can continuously detect distances to obtain the data acquisition results from the distance sensor.

[0050] Step S20: Based on the data acquisition results of the ranging sensor, determine that there is condensation at the lower air outlet and perform condensation control.

[0051] It should be noted that condensation refers to water droplets or mist that form on or near the lower air outlet when cold air is blown out. Once condensation is detected at the lower air outlet, condensation control is implemented to prevent condensation from dripping onto the ground or objects below the air conditioning unit, thus avoiding any impact on the user experience.

[0052] Distance sensors can be used to detect distances. When condensation is present on the distance sensor, the data detected by the distance sensor will change. Therefore, the data acquisition results of the distance sensor can be used to determine whether there is condensation at the air outlet and to control the condensation.

[0053] For example, based on the acquired data collection results, it is determined whether there is condensation at the lower air outlet. If it is determined that there is condensation at the lower air outlet, condensation control is performed to prevent condensation from continuing to be generated at the lower air outlet.

[0054] In this embodiment of the invention, a distance sensor is installed at the lower air outlet of the air conditioning unit, and part of the airflow direction at the lower air outlet is directed towards the distance sensor. This makes the distance sensor the most prone to condensation, thus facilitating the detection of condensation at the lower air outlet using the distance sensor. Specifically, during the operation of the air conditioning unit, the data acquisition results of the distance sensor can be obtained, and based on the data acquisition results, it can be determined that condensation exists at the lower air outlet, and condensation control can be implemented. This achieves condensation detection through the distance sensor, which can be used to detect distance. When condensation exists at the distance sensor, it indicates that the distance sensor is blocked by condensation, and the data acquisition results of the distance sensor will also change. Therefore, the presence of condensation at the lower air outlet can be determined and condensation control can be implemented through the data acquisition results of the distance sensor, without the need for detection by a dew point sensor. This avoids misjudgment due to the influence of wind speed and temperature at the lower air outlet, thereby improving the accuracy of condensation detection in the air conditioning unit.

[0055] In a feasible embodiment, step S20 further includes step S21:

[0056] Step S21: If the data acquisition results of the ranging sensor are abnormal after a preset number of consecutive steps, it is determined that there is condensation at the lower air outlet.

[0057] Among them, abnormal data acquisition results include: the distance detected by the ranging sensor is less than the preset first distance threshold, and the ranging sensor does not detect any distance.

[0058] It should be noted that the distance sensor calculates the distance to an object by emitting light pulses and measuring the time it takes for the light pulses to return. When condensation is present on the distance sensor, such as water droplets, mist, or a water film, the distance detected by the distance sensor will be very short or undetectable. For example, the light pulses emitted by the distance sensor may be scattered by condensation, which may lead to the distance sensor not detecting the distance or detecting a very short distance. Therefore, this embodiment of the invention can use a distance sensor to detect whether condensation exists at the air outlet.

[0059] The preset first distance threshold can be set based on actual conditions. For example, the preset first distance threshold can be set to 0.1m, etc. This embodiment does not specifically limit this. When the distance detected by the ranging sensor is less than the preset first distance threshold, it indicates that the distance detected by the ranging sensor is very short, and there may be condensation or water mist on the surface of the ranging sensor. When the ranging sensor does not detect any distance, it also indicates that there may be condensation or water mist on the surface of the ranging sensor.

[0060] The preset number of times can be set based on actual conditions, such as 3 times, 4 times, etc., and this embodiment does not make a specific limitation. This embodiment determines that condensation exists at the lower air outlet when abnormalities are detected in the data acquisition results after a preset number of consecutive tests, thereby ensuring the accuracy of condensation detection and avoiding inaccurate condensation detection caused by a single false detection by the ranging sensor.

[0061] Therefore, this embodiment improves the accuracy of condensation detection by using a distance sensor to detect whether condensation exists at the lower air outlet. Specifically, part of the airflow from the lower air outlet of the air conditioning unit is directed towards the distance sensor, making the sensor the most prone to condensation. This allows for faster detection of condensation at the lower air outlet, improving detection efficiency.

[0062] The distance sensor determines whether there is condensation at the lower air outlet by detecting the distance. Therefore, the data collected by the distance sensor is not affected by the airflow and temperature fluctuations at the lower air outlet. As long as there is condensation or water mist on the surface of the distance sensor, it can detect whether there is condensation at the lower air outlet, thereby improving the accuracy of condensation detection.

[0063] For example, if the data acquisition results from the ranging sensor show abnormalities for a preset number of consecutive cycles, condensation is determined to exist at the lower air outlet; if the number of consecutive cycles with abnormal data acquisition results from the ranging sensor is less than the preset number, condensation control can be omitted. Condensation control can also be omitted when the data acquisition results from the ranging sensor are normal. Normal data acquisition results include the distance detected by the ranging sensor being greater than or equal to a preset first distance threshold.

[0064] In addition, it should be noted that the ranging sensor has a very high detection frequency, for example, it can detect multiple times within 1 second. Therefore, if there are abnormalities in the data collection results after a preset number of consecutive tests, it can be determined that there is condensation at the air outlet, thus improving the condensation detection efficiency while ensuring detection accuracy.

[0065] In a feasible embodiment, step S20 further includes step X10:

[0066] Step X10: Output a condensation handling reminder; and / or, close the lower air outlet of the air conditioning unit; and / or, increase the air outlet temperature of the air conditioning unit.

[0067] It should be noted that condensation control can take several forms, such as issuing a condensation management reminder; and / or closing the lower air outlet of the air conditioner; and / or increasing the air outlet temperature of the air conditioner. The condensation management reminder alerts the user that condensation exists at the lower air outlet and needs to be cleaned. Closing the lower air outlet prevents the output of cold air, thus stopping condensation. Increasing the air outlet temperature slows down condensation formation, achieving the same effect.

[0068] Once condensation is detected at the lower air outlet, users can choose any one, two, or all three control methods to control condensation: output a condensation control reminder, close the lower air outlet of the air conditioner, or increase the air outlet temperature of the air conditioner. This improves the flexibility of condensation control.

[0069] Furthermore, in a feasible embodiment, the control method for the air conditioning equipment further includes step A10:

[0070] Step A10: Based on the data acquisition results from the ranging sensor, determine if there is a human body or obstacle below the lower air outlet, and implement wind avoidance control.

[0071] It should be noted that wind avoidance control means that the airflow direction of the lower air outlet avoids the location of people or obstacles. For example, wind avoidance control can be to close the lower air outlet or adjust the airflow direction of the lower air outlet to prevent the airflow from blowing towards people or obstacles. It should also be noted that when adjusting the airflow direction of the lower air outlet, it is still necessary to ensure that part of the airflow from the lower air outlet is directed towards the distance sensor located at the lower air outlet. If, during wind avoidance control, part of the airflow from the lower air outlet is directed towards the distance sensor but still blows towards people or obstacles, the lower air outlet can be closed directly to avoid affecting the user experience and to avoid affecting the detection of condensation at the lower air outlet.

[0072] For example, based on the data collected by the ranging sensor, it can be determined whether there is a person or obstacle below the air outlet. If a person or obstacle is present, wind avoidance control is implemented. If no person or obstacle is present, wind avoidance control may not be implemented.

[0073] In a feasible embodiment, step A10 further includes step A11:

[0074] Step A11: If the distance detected by the ranging sensor is greater than a preset first distance threshold and less than a preset second distance threshold, it is determined that there is a human body or obstacle below the lower air outlet.

[0075] It should be noted that the preset second distance threshold can be set based on actual conditions, and the preset second distance threshold is greater than the preset first distance threshold. The data acquisition results of the ranging sensor include the distance detected by the ranging sensor.

[0076] If the distance detected by the distance sensor is greater than a preset first distance threshold, it indicates that there is no condensation at the distance sensor location. If the distance detected by the distance sensor is greater than the preset first distance threshold but less than a preset second distance threshold, it indicates that there is a person or obstacle below the lower air outlet of the air conditioning unit. In this case, wind avoidance control is required to improve the user experience.

[0077] For example, when the distance detected by the ranging sensor is greater than a preset first distance threshold and less than a preset second distance threshold, it is determined that there is a human body or obstacle below the lower air outlet; when the distance detected by the ranging sensor is greater than the preset second distance threshold, wind avoidance control can be omitted.

[0078] In one feasible embodiment, the control method for the air conditioning equipment further includes step B10 and / or step B20:

[0079] Step B10: Receive distance calibration instruction, detect the current distance to the air outlet of the air conditioning device through the distance sensor, and update the preset second distance threshold based on the current distance;

[0080] It should be noted that the distance calibration indicator is used to indicate the distance to the air outlet of the air conditioning unit. The distance calibration indicator can be initiated by the user or automatically triggered by the air conditioning unit during installation. This embodiment does not make specific limitations on this.

[0081] For example, after an air conditioning unit is installed, the distance sensor on the unit can automatically detect the current distance below the lower air vent and use this current distance as a preset second distance threshold. When the environment around the air conditioning unit changes, the user can also initiate a distance calibration instruction. Upon receiving the instruction, the distance sensor will detect the current distance below the lower air vent and update the preset second distance threshold based on this distance. For example, the detected current distance can be directly used as the preset second distance threshold to update it.

[0082] This embodiment receives a distance calibration instruction and then updates a preset second distance threshold based on the detected current distance. This allows it to adapt to changes in the environment where the air conditioning device is located, making it easier for the air conditioning device to more accurately detect whether there are obstacles or people below the lower air outlet, thus improving the user experience.

[0083] Step B20: Periodically detect the current distance to the air outlet of the air conditioning device using a distance sensor, and update the preset second distance threshold based on the current distance.

[0084] It should be noted that this embodiment can also periodically detect the current distance below the air outlet of the air conditioning device, and periodically update the preset second distance threshold based on the periodically detected current distance. This eliminates the need for user-instructed updates to the preset second distance threshold, improving the intelligence of the air conditioning device and enhancing the user experience.

[0085] The period for detecting the current distance below the air outlet can be set based on the actual situation. For example, it can be detected every morning or every Tuesday morning. This embodiment does not make any specific limitation on this.

[0086] In one feasible embodiment, the step of determining that a portion of the airflow from the lower air outlet of the air conditioning unit is directed toward a ranging sensor located at the lower air outlet includes step C10 or step C20:

[0087] Step C10: Control the airflow direction of the blades near the distance sensor inside the lower air outlet of the air conditioning equipment toward the distance sensor.

[0088] It should be noted that the airflow direction of the blades near the distance sensor within the lower air outlet can be controlled to face the distance sensor, so that part of the airflow at the lower air outlet faces the distance sensor. The blades near the distance sensor can be determined based on the distance between the blades within the lower air outlet and the distance sensor. The nearby blades can be one or more, etc., and this embodiment does not specifically limit this.

[0089] For example, refer to Figure 2 In this embodiment, the ranging sensor can be located on the left side of the lower air outlet. Figure 2 This demonstrates one method of mounting a ranging sensor on an air conditioning unit. Figure 2 In this embodiment, T refers to the Time-of-Flight (TOF) sensor, D1, D2, and D3 represent the guide vanes at the lower air outlet, and F indicates the airflow direction of D1 to D3. For example, the airflow direction indicated by F is towards the TOF sensor. This embodiment determines that the airflow direction of the vanes adjacent to the ranging sensor is towards the ranging sensor, thereby facilitating the fastest possible condensation generation at the ranging sensor. Additionally, in other embodiments, reference can be made to... Figure 3 , Figure 3 This diagram shows another example of a distance sensor installed at the lower air outlet. Figure 3 In this context, "T" refers to the Time-of-Flight (TOF) sensor. Figure 3The Time-of-Flight (TOF) sensor can be positioned below the lower air outlet. Y1 to Y7 are all guide vanes of the lower air outlet, and the airflow direction of the guide vanes is all towards the ranging sensor T. FX indicates the airflow direction of the guide vanes of the lower air outlet.

[0090] Step C20: Control the airflow direction of the preset air duct of the air conditioning equipment towards the distance sensor.

[0091] It should be noted that a preset air duct can be set on the air conditioning equipment, and the airflow direction of the preset air duct can be controlled to be towards the distance sensor. This makes it easier for condensation to occur at the location of the distance sensor, so that condensation can be detected more quickly at the lower air outlet. Therefore, the method for detecting condensation at the lower air outlet in this embodiment of the invention can be applied to various air conditioning equipment, such as air conditioning equipment with a preset air duct or air conditioning equipment without a preset air duct.

[0092] Air conditioning equipment can be equipped with main air ducts and auxiliary air ducts. The preset air duct can be the auxiliary air duct, thereby improving the detection efficiency of condensation without affecting the performance of the air conditioning equipment.

[0093] In one feasible embodiment, the ranging sensor is a time-of-flight (TOF) sensor, and the surface of the ranging sensor is covered with an infrared filter.

[0094] It should be noted that the ranging sensor can be a Time-of-Flight (TOF) sensor. TOF is a sensor technology that uses light pulses to measure the distance to an object. For example, a TOF sensor first emits a modulated infrared light pulse, which can be in the form of pulse modulation or continuous wave modulation. When the emitted light pulse encounters a target object, it is reflected back by the object's surface and captured by the TOF sensor. The TOF sensor calculates the distance between the target object and the TOF sensor by measuring the time difference between the emission and reception of the light pulse (i.e., the time of flight) and combining this with the speed of light (approximately 0.3 meters per nanosecond). For example, the target object could be an object near the lower air vent of an air conditioning unit, such as a floor or sofa; this embodiment does not specifically limit this.

[0095] An infrared filter can also be placed on the surface of the ranging sensor to reduce interference with the ranging sensor and improve the accuracy of the ranging sensor's detection distance.

[0096] To better understand this embodiment, please refer to Figure 4The process of this embodiment is briefly described as follows: First, step Y10 is performed: Time-of-Flight (TOF) sensor calibration; this ensures the accuracy of the TOF sensor's detection. The TOF sensor calibration process may include a series of standard steps to adjust and optimize the sensor's parameters to ensure measurement accuracy. For example, standard steps may include calibrating the resolution of the TOF sensor. Next, step Y20 is performed: detecting the distance below the lower air outlet; the TOF sensor detects the distance below the lower air outlet. It can be understood that the data acquisition result of the ranging sensor is the distance below the lower air outlet detected by the TOF sensor. Step Y30: Is the data acquisition result abnormal? Abnormal data acquisition results include: the detection distance is less than the preset first distance threshold, or no distance is detected. If the data acquisition result is abnormal, proceed to step Y31: If abnormality is detected for a preset number of consecutive times, condensation control is implemented. If the data acquisition result is not abnormal, proceed to step Y40: Is the detection distance greater than the preset first distance threshold and less than the preset second distance threshold? If the detection distance is greater than the preset first distance threshold and less than the preset second distance threshold, proceed to step Y41: If there is a person or obstacle below the lower air outlet, wind avoidance control is implemented. If the detection distance is greater than the preset second distance threshold, you can return to step Y20 to continue detecting the distance below the lower air outlet. After completing either step Y41 or step Y31, the current condensation detection process can be terminated.

[0097] This invention also provides a control device 30 for an air conditioning equipment, see reference. Figure 5 The air outlet of the air conditioning unit is partially oriented towards the distance sensor located at the lower air outlet; the control device 30 of the air conditioning unit includes:

[0098] The acquisition module 10 is used to acquire the data collection results of the ranging sensor during the operation of the air conditioning equipment;

[0099] The control module 20 is used to determine whether there is condensation at the lower air outlet based on the data acquisition results of the ranging sensor, and to control the condensation.
