Abstract
Description
Technical Field

[0002] Air conditioners are now essential appliances for homes and offices, especially during the summer and winter months when they are used for extended periods. Air conditioners can control their operation based on ambient temperature feedback from temperature sensors, including automatically adjusting parameters such as output mode, compressor operating frequency, and fan speed.
[0003] Currently, during air conditioner operation, the indoor unit discharges the heated air through a filter. This filter removes dust from the air. After a period of use, a large amount of dust accumulates on the filter, causing it to become clogged. This not only affects the air conditioner's heat exchange performance but also the filter's effectiveness in filtering the air. However, due to the frequency of air conditioner use and its operating environment, current methods for determining air conditioner clogging are not intelligent enough and have low accuracy, requiring further improvement.

The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure.

It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.
[0047] Unless otherwise stated, the term "multiple" means two or more.
[0048] In this embodiment of the disclosure, the character " / " indicates that the objects before and after it are in an "or" relationship. For example, A / B means: A or B.
[0049] 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.
[0050] The air conditioner filter includes a plastic frame and a mesh fabric. The plastic frame divides the mesh fabric into two or more parts. The air conditioner filter is installed in the track groove of the indoor unit of the air conditioner. Under the action of wind pressure and its own gravity, it has an arc-shaped curve. Different degrees of dirt and clogging of the air conditioner filter correspond to different arc curves. Therefore, in this embodiment, two or more position detection devices can be configured on the filter screen. In this way, under the same set air volume, the first position value collected by each position detection device in the usage situation is compared with the standard position value under the corresponding zero dirt and clogging condition to obtain the absolute height difference between the two. Based on the absolute height difference, filter dirt and clogging is detected. This realizes automatic detection of filter dirt and clogging, improves the accuracy of filter dirt and clogging detection, and allows for timely filter dirt and clogging treatment, ensuring effective filtration and air conditioning capacity, and improving user experience.
[0051] Figure 1 This is a schematic flowchart of a method for detecting dirt and clogging in an air conditioning filter, provided in an embodiment of this disclosure. Two or more position detection devices are configured on a designated component on the air conditioning filter, such as... Figure 1 As shown, the process for detecting a dirty or clogged air conditioning filter includes:
[0052] Step 101: Under the set air volume, obtain the first position value collected by each position detection device and generate the corresponding first position shape curve.
[0053] Two or more position detection devices are installed at designated positions on the plastic frame or mesh of the air conditioner filter, so that each position detection device can collect a corresponding position value. The position value may include one or more of the following: a height value relative to the ground, a horizontal value relative to the air conditioner frame, etc.
[0054] In some embodiments, two or more position detection devices may be longitudinally arranged on the first mesh fabric of the air conditioning filter. The filter includes a plastic frame and a mesh fabric, the plastic frame dividing the mesh fabric into two or more sections, with the first mesh fabric located in the middle section of the filter. Thus, during operation, the air conditioner can obtain a first position value for the area corresponding to each position detection device through the two or more position detection devices longitudinally arranged on the first mesh fabric of the air conditioning filter.
[0055] Figure 2 This is a schematic diagram of a position detection device configured on an air conditioning filter according to an embodiment of this disclosure. Figure 2 As shown, multiple position sensors are longitudinally arranged on the middle part of the filter screen, i.e., the first mesh fabric.
[0056] Of course, this disclosure is not limited to this. Two or more position detection devices can also be configured on the plastic frame. Similarly, different degrees of filter clogging correspond to different pressures. Under the action of pressure and its own gravity, the position of the plastic frame will also change. That is, during operation, the air conditioner can obtain the position value of the corresponding point under the action of wind pressure and its own gravity through each position sensor, that is, obtain the first position value of the area corresponding to each position detection device.
[0057] It can be seen that during the operation of the air conditioner, under the set air volume, the first position value collected by each position detection device includes: the height value of the corresponding point after the mesh is subjected to wind pressure and gravity.
[0058] In this embodiment of the disclosure, when detecting air conditioner filter clogging, it is necessary to control the fan of the indoor unit of the air conditioner to generate a set air volume. That is, the fan of the indoor unit of the air conditioner is controlled to run at a first speed to generate the set air volume. For example, the air conditioner controls the indoor unit fan speed n = 900 to maintain a constant suction force on the air intake side. Of course, the fan speed n can be determined according to the air conditioner model, the season of use, and the geographical area, and can be different values such as 600, 800, 1000, etc.
[0059] In this way, the first position value collected by each position detection device can be obtained under a set air volume, and a corresponding first position shape curve can be generated based on each first position value.
[0060] Step 102: Compare the first position shaping curve with the standard position curve to obtain the absolute height difference between each first position value and the corresponding standard position value, and determine the statistical quantity corresponding to the absolute height difference greater than the set value. The standard position curve is obtained and saved under the condition of zero dirt and clogging of the filter.
[0061] In this embodiment of the disclosure, when detecting air conditioner filter clogging, the corresponding reference standard is the standard position value collected by each position detection device under the condition of zero filter clogging. That is, under the condition of set airflow and zero filter clogging, the position value collected by each position detection device is obtained and saved as the standard position value. Then, a corresponding standard position curve can be generated based on each standard position value. Generally, the standard position values can be obtained and saved when the air conditioner leaves the factory or when the air conditioner is first run after installation.
[0062] In this way, during the operation of the air conditioner, after acquiring the first position value collected by each position detection device under the set air volume, the air conditioner can obtain the absolute position difference between each first position value and the corresponding standard position value.
[0063] An air conditioner filter is equipped with n position detection devices. Under the condition of set airflow and zero filter clogging, n standard position values can be saved, namely Hb1, Hb2, ..., Hbn. When the air conditioner is running, at the set airflow, the first position values obtained by the air conditioner through the n position detection devices are H1, H2, ..., Hn. Thus, the absolute position differences between each first position value and its corresponding standard position value are: Δ1 = |H1 - Hb1|, Δ2 = |H2 - Hb2|, ..., Δn = |Hn - Hbn|.
[0064] The position detection device detects the position value generated by wind pressure and gravity after the mesh passes through. When a part of the mesh becomes dirty and clogged, the position at that location will deform more due to the increased wind pressure, causing the curve to dip locally. Therefore, the higher the degree of clogging, the greater the corresponding absolute position difference will be.
[0065] It is evident that the greater the degree of clogging of the filter, the greater the corresponding absolute position difference. In some embodiments, a set value can be configured. When the absolute position difference Δ is greater than the set value, it indicates that the area where the corresponding position detection device is located is relatively clogged. Therefore, the number of absolute position differences greater than the set value can be counted, that is, the statistical quantity corresponding to the absolute position differences greater than the set value can be determined.
[0066] The set value can be 8mm, 9mm, 10mm, 12mm, etc., depending on the performance of the air conditioner.
[0067] Step 103: If the number of items counted exceeds the set number, clean the air conditioning filter to remove dirt and clogging.
[0068] The number can be set to 1, 2, 3, or 4, etc. For example, if the number is set to N=1, then if the count is greater than 1, it indicates that the area where two or more location detection devices are located is relatively dirty and clogged. Therefore, the air conditioner can determine that the air conditioner filter is relatively dirty and clogged and needs to be cleaned, and the air conditioner filter can be cleaned.
[0069] In some embodiments, the process of cleaning up a clogged air conditioning filter includes: if the difference between the current absolute positions is greater than a set value, determining the current area corresponding to the current position detection device corresponding to the difference between the current absolute positions as the current clogged area; and issuing a filter clog reminder based on the current clogged area.
[0070] Filter clogging alerts can be provided through one or more methods, such as sound, light, or electricity. For example, a text alert can be displayed on the air conditioner screen, along with a voice message. This allows the air conditioner to alert users based on the specific area of clogging, enabling them to focus on cleaning that area when cleaning the air conditioner filter.
[0071] In some embodiments, addressing air conditioning filter clogging includes: determining the degree of filter clogging in the area corresponding to each location detection device based on the absolute position difference; and issuing a filter clogging alert based on the degree of clogging.
[0072] Regardless of where the position detection device is located on the filter, the greater the degree of filter clogging, the greater the corresponding absolute position difference. Therefore, the air conditioner can maintain a correspondence between the absolute position difference and the degree of filter clogging. Based on this correspondence, the air conditioner can determine the degree of filter clogging in the area corresponding to each position detection device and then issue a filter clogging alert accordingly.
[0073] Table 1 shows the correspondence between absolute position difference and filter clogging degree provided in the embodiments of this disclosure.
[0074] Absolute position difference △ degree of filter clogging 0mm≤△<2mm 0％ 2mm≤△<4mm 10％ 4N≤△<6mm 20％ 6mm≤△<8mm 30％ 8mm≤△<10mm 40％ …… ……
[0075] Table 1
[0076] As shown in Table 1, if △1 = 2mm, the filter clogging level in the area corresponding to position detection device 1 is determined to be 10%; if △3 = 9mm, the filter clogging level in the area corresponding to position detection device 3 is determined to be 40%. Thus, to provide a filter clogging reminder, the air conditioner can display the area corresponding to the position detection device and the corresponding filter clogging level on the air conditioner screen, provide a voice reminder, or send the information to the user terminal via the network, etc.
[0077] Similarly, when cleaning a clogged air conditioning filter, users can follow the prompts to perform different cleaning processes depending on the degree of clogging. For example, the more clogged the filter, the more times the corresponding area needs to be cleaned, or the stronger the water used for cleaning, etc. Specific examples will not be listed here.
[0078] Of course, in some embodiments, after determining the degree of filter clogging in the area corresponding to each location detection device, the air conditioner can count the number of filters with a clogging degree greater than a set value, determine this as the number of clogging points, and perform air conditioner filter clogging treatment if the number of clogging points is greater than the set value. For example: Δ2 = 8mm corresponds to a filter clogging degree of 40%, and Δ3 = 9mm also corresponds to a filter clogging degree of 40%, and Δ4 = 11mm also corresponds to a filter clogging degree of 50%. If the set value is 30%, 40% > 30%, and 50% > 30%, then the number of clogging points is 3, which is greater than the set value of 2. Therefore, the air conditioner can also perform filter clogging treatment.
[0079] As can be seen, in this embodiment of the present disclosure, two or more position detection devices can be configured at a set position on the filter. In this way, under the same set air volume, the air conditioner compares the first position value collected by each position detection device during use with the corresponding standard position value under zero clogging conditions to obtain the absolute position difference between the two. Based on the absolute position difference, filter clogging can be detected. This achieves automatic detection of filter clogging, improves the accuracy of filter clogging detection, and allows for timely filter clogging treatment, ensuring effective filtration and air conditioning capacity, and improving user experience.
[0080] The following describes the operation process in a specific embodiment, illustrating the process for detecting dirt and clogging in air conditioning filters provided by the embodiments of the present invention.
[0081] In one embodiment of this disclosure, such as Figure 2 As shown, multiple position sensors are longitudinally arranged on the middle part of the filter, i.e., the first mesh fabric. The air conditioner saves the height value (based on the ground) collected by each position sensor when the airflow is set and the filter is completely free of dirt and clogging. After saving it as a standard height value, a standard position curve is generated, as shown. Figure 3 As shown, h is the height value collected by the position sensor, and C is the longitudinal relative position of the position sensor on the first mesh. Furthermore, the air conditioner stores the corresponding relationship shown in Table 1, with a setting degree of 30% and a setting quantity of 1.
[0082] Figure 4 This is a schematic flowchart of a method for detecting dirt and clogging in an air conditioning filter, provided in an embodiment of this disclosure. Figure 4 As shown, the air conditioner filter clogging detection process includes:
[0083] Step 401: Control the fan of the indoor unit of the air conditioner to run at a speed of 900 rpm.
[0084] Step 402: The air conditioner obtains the first height value of the corresponding position through each position sensor, namely H1, H2, ..., and generates the corresponding first position shape curve.
[0085] When a section of the filter mesh becomes clogged with dirt, the area experiences increased wind pressure, leading to greater deformation and a localized concave curve in the filter's shape. Figure 5 As shown, in the state of dirt blockage, the height at some locations decreases.
[0086] Step 403: The air conditioner compares the first position shape curve with the standard position curve to obtain the absolute position difference Δ between each first height value and the corresponding standard height value.
[0087] Where Δ1 = |H1-Hb1|, Δ2 = |H2-Hb2|, ...
[0088] Step 404: According to Table 1, the air conditioner determines the degree of filter clogging corresponding to each absolute position difference Δ, and counts the number of filters with a degree of clogging greater than 30%, which is determined as the number of clogging filters.
[0089] If Δ1 = 4mm, Δ2 = 8mm, Δ3 = 3.5mm, Δ4 = 9mm, ... according to Table 1, the corresponding filter clogging degrees are 30%, 40%, 30%, 40%, ... then the number of clogging filters with a clogging degree greater than 30% is counted.
[0090] Step 405: Determine if the number of blocked or clogged items is greater than 1. If yes, proceed to step 406; otherwise, end the process.
[0091] Step 406: The air conditioner will issue a filter clogging reminder based on the degree of filter clogging.
[0092] As can be seen, in this embodiment, multiple position sensors are longitudinally arranged on the middle part of the filter, i.e., the first mesh fabric. In this way, under the same set air volume, the air conditioner compares the first height value collected by each position sensor during use with the standard height value under the corresponding zero-clogging condition to obtain the absolute position difference between the two. Based on the absolute position difference, filter clogging can be detected. This achieves automatic detection of filter clogging, improves the accuracy of filter clogging detection, and allows for timely filter clogging treatment, ensuring effective filtration and air conditioning capacity, and improving user experience.
[0093] Based on the above process for detecting dirt and clogging in air conditioning filters, a device for detecting dirt and clogging in air conditioning filters can be constructed.
[0094] Figure 6 This is a schematic diagram of a device for detecting dirt and clogging in an air conditioning filter, provided in an embodiment of this disclosure. Two or more position detection devices are configured on a designated component on the air conditioning filter, such as... Figure 6 As shown, the air conditioner filter clogging detection device 600 includes: a position acquisition module 610, a comparison and statistics module 620, and a detection and processing module 630.
[0095] The position acquisition module 610 is configured to acquire the first position value collected by each position detection device under a set air volume, and generate the corresponding first position shape curve.
[0096] The comparison and statistics module 620 is configured to compare the first position shaping curve with the standard position curve to obtain the absolute height difference between each first position value and the corresponding standard position value, and to determine the statistical quantity corresponding to the absolute height difference greater than the set value. The standard position curve is obtained and saved under the condition of zero dirt clogging of the filter.
[0097] The detection and processing module 630 is configured to perform air conditioning filter clogging treatment when the number of detected filters exceeds a set number.
[0098] In some embodiments, it also includes:
[0099] The fan control module is configured to control the fan of the indoor unit of the air conditioner to run at a first speed to generate a set air volume.
[0100] In some embodiments, it also includes:
[0101] The standard storage module is configured to acquire the position values collected by each position detection device and save them as standard position values when the air volume is set and the filter is free of dirt and clogging; and generate corresponding standard position curves based on the standard position values.
[0102] In some embodiments, the location acquisition module 610 includes:
[0103] The first acquisition unit is configured to acquire the first position of the area corresponding to each position detection device by using two or more position detection devices arranged longitudinally on the first mesh of the air conditioner filter.
[0104] The filter screen includes a plastic frame and a mesh fabric. The plastic frame divides the mesh fabric into two or more parts, with the first mesh fabric located in the middle part of the filter screen.
[0105] In some embodiments, the detection processing module 630 is specifically configured to determine the current area corresponding to the current position detection device corresponding to the current absolute height difference as the current clogged area when the current absolute height difference is greater than a set value; and to perform filter clog reminder processing based on the current clogged area.
[0106] In some embodiments, the detection processing module 630 is specifically configured to determine the degree of filter clogging in the area corresponding to each position detection device based on the absolute position difference; and to perform filter clogging reminder processing based on the degree of filter clogging.
[0107] The following describes the air conditioning filter clogging detection process for the air conditioning filter clogging detection device in further detail with reference to the embodiments.
[0108] In this embodiment, as Figure 2 As shown, multiple position sensors are longitudinally arranged on the middle part of the filter, i.e., the first mesh. The air conditioner stores the correspondence shown in Table 1, with a setting degree of 30% and a setting quantity of 1.
[0109] Figure 7 This is a schematic diagram of a device for detecting dirt and clogging in an air conditioning filter, provided in an embodiment of this disclosure. Figure 7As shown, the air conditioner filter clogging detection device 600 includes: a position acquisition module 610, a comparison and statistics module 620, a detection and processing module 630, a fan control module 640, and a standard storage module 650, wherein the position acquisition module 610 includes a first acquisition unit 611.
[0110] In this embodiment, when the air conditioner filter is free of dirt and clogging, the fan control module 640 controls the fan of the indoor unit of the air conditioner to run at a speed of 900 revolutions per minute. In this way, the standard storage module 650 can obtain the height value collected by each position sensor and save it as a standard height value, namely Hb1, Hb2, Hb3, ..., and generate the corresponding standard position curve.
[0111] Thus, after the air conditioner starts operating, during the air conditioner filter inspection, the fan control module 640 similarly controls the indoor unit fan to run at a speed of 900 rpm. The first acquisition unit 611 in the position acquisition module 610 acquires the corresponding first height values (H1, H2, H3…) through each position sensor and generates the corresponding first position shaping curve. The comparison and statistics module 620 compares the first position shaping curve with the standard position curve to obtain the absolute position difference Δ between each first height value and the corresponding standard height value. Based on Table 1, it determines the degree of filter clogging corresponding to each absolute position difference Δ and counts the number of filters with a clogging degree greater than 30%, defining this as the number of clogged filters.
[0112] In this way, when the number of clogs is greater than 1, the detection and processing module 630 can provide a filter clogging reminder based on the degree of filter clogging.
[0113] As can be seen, in this embodiment, multiple position sensors are longitudinally arranged on the middle part of the mesh, i.e., the first mesh fabric. Thus, under the same set air volume, the device for detecting filter clogging compares the first height value collected by each position sensor during use with the corresponding standard height value under zero clogging conditions to obtain the absolute position difference between the two. Based on the absolute position difference, filter clogging can be detected. This achieves automatic detection of filter clogging, improves the accuracy of filter clogging detection, and allows for timely filter clogging treatment, ensuring effective filtration and air conditioning capacity, and enhancing the user experience.
