[0023] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0024] The embodiment of the present application provides an air conditioner and a self-cleaning method, wherein the air conditioner can achieve self-cleaning, which is described in detail below with reference to the accompanying drawings.

[0025] See also Figure 1 as well as Figure 2 , Figure 1A first structural diagram of an air conditioner provided in an embodiment of the present application, Figure 2 A second structural schematic diagram of the air conditioner provided in an embodiment of the present application.

[0026] The air conditioner 100 provided in the embodiment of the present application includes a housing 10, a sensor 20, a dust removal mechanism 30 and a processor. The air conditioner 100 may be an indoor unit of the air conditioner 100. The indoor unit of the air conditioner 100 includes but is not limited to a wall mounted air conditioner, a ceiling mounted air conditioner or a window mounted air conditioner.

[0027] The housing 10 has an air outlet and a storage space, and the air outlet is connected to the storage space. The housing 10 plays a role in protecting the internal structure of the air conditioner 100. The flowing air generated by the fan of the air conditioner 100 is sent out from the air outlet.

[0028] The sensor 20 is disposed at the air outlet and can detect particles in the flowing air blown out from the air outlet.

[0029] The dust removal mechanism 30 is disposed in the accommodation space and can remove dust on the surface of the structure in the accommodation space to achieve a self-cleaning function of the air conditioner 100 .

[0030] The processor is connected to the sensor 20 and the dust removal mechanism 30, and is used to implement the following steps.

[0031] The content of particulate matter in the flowing air blown out from the air outlet detected by the sensor 20 is obtained.

[0032] If the content of the particulate matter is greater than or equal to the preset value, the dust removal mechanism 30 is turned on.

[0033] For example, the sensor 20 is a PM2.5 sensor, which can detect the content of particulate matter in the flowing air blown out from the air outlet. The preset value can be 10 micrograms / cubic meter. The processor is used to obtain the content of particulate matter in the flowing air blown out from the air outlet detected by the sensor 20, and the dust removal mechanism 30 is turned on. In this example, the preset value of 10 micrograms / cubic meter is only for illustration, and the preset value can also be other values, such as 4 micrograms / cubic meter, 5 micrograms / cubic meter, 6 micrograms / cubic meter, 7 micrograms / cubic meter, 8 micrograms / cubic meter or 9 micrograms / cubic meter.

[0034] Of course, the particulate matter may be dust and impurities, and the sensor 20 may also be a dust sensor or an infrared dust particle sensor or a micro infrared dust particle sensor for detecting the dust content.

[0035] As described above, the quality of the air blown out of the air outlet is detected by the sensor 20 to indirectly obtain the dust condition on the surface of the structure in the accommodation space, and then the dust removal mechanism 30 can remove the dust on the surface of the structure to realize the self-cleaning function of the air conditioner 100.

[0036] In some embodiments, in order to solve the problems in the prior art of installing a mechanical cleaning device for automatically cleaning the filter or evaporator in the air conditioner 100, which occupies a large space in the air conditioner 100, has a limited cleaning range, and is easily damaged, please continue to refer to Figure 2 The dust removal mechanism 30 in the embodiment of the present application includes a motor 31 and a surface acoustic wave filter 32. The surface acoustic wave filter 32 is configured to receive and amplify the sound signal generated by the motor 31 to realize the acoustic wave cleaning function, so as to cause the particles in the accommodation space to vibrate. The acoustic wave cleaning function refers to using the wave characteristics of sound waves to vibrate particles such as dust and impurities attached to the surface of the structure in the accommodation space, so that the particles fall off the surface of the structure.

[0037] For example, the audio generated by the rotation of the motor 31 is received and filtered by the surface acoustic wave filter 32, and then the surface acoustic wave filter 32 filters out the sound in the frequency range of 60 to 120 Hz and amplifies it to vibrate the particles in the accommodation space of the air conditioner 100, so that the particles fall off the surface of the structure.

[0038] The motor 31 is a fan motor for driving a fan, which realizes structural reuse, does not hinder the original structural combination and functional use of the air conditioner 100, and has little effect on the size of the air conditioner 100. The fan motor 31 of the air conditioner 100 is used as a sound wave generator, and the low-frequency sound is amplified by the surface acoustic wave filter 32 to vibrate and fall off the particles attached to the internal structure of the air conditioner 100, so that the cleaning range is more comprehensive and no more energy is consumed.

[0039] In some embodiments, the air conditioner 100 further includes an indicator 40 , which is disposed on an outer surface of the housing 10 , and the processor is connected to the indicator 40 , and the indicator has different states.

[0040] The processor is used to compare the relationship between the content of particulate matter and the preset value. When the content of particulate matter is greater than or equal to the preset value, the indicator 40 is controlled to be in the first state. When the content of particulate matter is less than the preset value, the indicator 40 is controlled to be in the second state. The first state is different from the second state and is used to respectively indicate the relationship between the content of particulate matter and the preset value.

[0041] For example, the indicator 40 is an indicator light, and the indicator light has different colors to indicate different states, such as the indicator light is red in the first state and green in the second state. When the indicator light presents different colors, the user can intuitively know the accumulation degree of dust, impurities and other particles inside the air conditioner 100. The user can also issue a dust removal command through the remote control, and the processor of the air conditioner 100 drives the dust removal mechanism 30 after receiving the dust removal command of the remote control to achieve manual dust removal.

[0042] When the indicator 40 is an indicator light, the indicator light may be a breathing light. The soft light state presented by the breathing light can reduce the light influence and interference on the user's sleep at night.

[0043] For another example, the indicator 40 is a display panel, and the display content of the display panel can point to different states. For example, when the display panel displays "dirty", it is the first state of the indicator 40; when the display panel displays "clean", it is the second state of the indicator 40. Of course, in the first state and the second state, a graded display can also be performed to indicate different degrees of cleanliness or dirtiness.

[0044] It is worth noting that the indicator 40 provided in the embodiment of the present application is an indicator light or a display panel for illustrative purposes only. If there are other structures or methods that can enable the user to intuitively or relatively intuitively know the degree of accumulation of particles such as dust and impurities inside the air conditioner 100, they are all within the protection scope of the embodiment of the present application.

[0045] In some embodiments, in order to reduce the frequent self-start of the dust removal mechanism 30, so as to save energy and reduce noise, the processor is also used to: control the sensor 20 to obtain particulate matter in the flowing air blown out of the air outlet each time the air conditioner 100 is turned on. When the air conditioner 100 is turned on multiple times and the content of particulate matter obtained by the sensor 20 each time is greater than or equal to the preset value, the dust removal mechanism 30 is turned on.

[0046] The air conditioner 100 is turned on multiple times means that the number of times it is turned on is greater than or equal to 2 times. For example, the number of times the air conditioner 100 is turned on is 3 times. When the air conditioner 100 is turned on for 3 consecutive times, and the content of particulate matter obtained by the sensor 20 each time is greater than or equal to the preset value, the air conditioner 100 automatically turns on the dust removal mechanism 30.

[0047] Of course, users can set the detection method by themselves, and can set the air conditioner 100 to be turned on 1 time, 2 times, 4 times or 5 times, so as to adjust the sensitivity of the air conditioner 100 to the content of particulate matter in the accommodating space, thereby saving energy consumption and reducing noise or improving cleaning ability.

[0048] In some embodiments, when the dust removal mechanism 30 is turned on, the processor is used to: calculate the working time of the dust removal mechanism 30; and when the working time of the dust removal mechanism 30 reaches a first time period, turn off the dust removal mechanism 30.

[0049] The first time period may be 2 to 10 minutes, for example 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes or 9 minutes.

[0050] The dust removal mechanism 30 emits a large sound wave to vibrate the dust impurities and other particles attached to the internal structure of the air conditioner 100, so that the dust impurities and other particles that are vibrated out float in the air in the accommodation space again. After the dust removal mechanism 30 stops working after vibrating for 3 minutes, the particles can be deposited on the dust collection mechanism 50 due to the neutralizing effect of their own gravity.

[0051] In some cases, after turning off the dust removal mechanism 30 and leaving it stationary for a first period of time, the processor is also used to again obtain the content of particulate matter in the flowing air blown out of the air outlet detected by the sensor 20; if the content of particulate matter is greater than or equal to a preset value, the dust removal mechanism 30 is turned on again until the content of particulate matter is less than the preset value.

[0052] In some embodiments, see Figure 3 , Figure 3 A third structural schematic diagram of the air conditioner provided in the embodiment of the present application: Figure (1) shows the pop-up state of the integrated box of the air conditioner, and Figure (2) shows the retracted state of the integrated box of the air conditioner. The air conditioner 100 also includes a dust collecting mechanism 50, and the dust collecting mechanism 50 includes a dust collecting box and a transmission structure, and the transmission structure is respectively connected to the dust collecting box and the shell 10. The processor is electrically connected to the transmission structure. The processor is used to: if the content of particulate matter is greater than or equal to a preset value, control the movement of the transmission structure to drive the dust collecting box to be located at the air outlet; when the dust removal mechanism 30 is closed, calculate the closing time of the dust removal mechanism 30, and when the closing time of the dust removal structure is after the second time period, control the transmission structure to drive the dust collecting box to move into the accommodating space.

[0053] The integrated mechanism may be disposed at the bottom 11 of the air conditioner 100 to facilitate receiving particles deposited by gravity.

[0054] The transmission structure can be a clockwork spring.

[0055] The second time period may be 2 to 10 minutes, for example 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes or 9 minutes.

[0056] While the dust removal mechanism 30 is working, the processor is used to control the transmission structure of the dust box on the bottom 11 of the air conditioner 100 to be energized, and the dust box is ejected to the air outlet.

[0057] When the dust removal mechanism 30 stops working for a period of time, the transmission structure of the dust box on the bottom 11 of the air conditioner 100 is powered on again, the dust box is retracted into the accommodating space, the air conditioner 100 ends the self-cleaning function and resumes normal operation.

[0058] In some cases, before controlling the transmission structure to drive the dust box to move into the accommodation space and after the dust removal structure is closed for a second period of time, the processor is also used to obtain the content of particulate matter in the flowing air blown out of the air outlet detected by the sensor 20 again; if the content of particulate matter is greater than or equal to the preset value, the dust removal mechanism 30 is turned on again until the content of particulate matter is less than the preset value, at which time the processor controls the dust box to be retracted into the accommodation space, the air conditioner 100 ends the self-cleaning function, and resumes normal operation. In this case, multiple transmissions of the integrated mechanism can be avoided, thereby improving the dust removal efficiency of the air conditioner 100.

[0059] In some embodiments, the air conditioner 100 further includes an air guide plate 60, which is located at the air outlet, connected to the housing 10, and the sensor 20 is disposed on the air guide plate 60. Optionally, the sensor 20 is disposed at the edge of the air guide plate 60. It is understandable that since the flowing air blown out from the air outlet passes through the air guide plate 60, the sensor 20 is disposed on the air guide plate 60 to improve the detection efficiency of the sensor 20.

[0060] In some scenarios, the scenario provides an air conditioner 100, which can be a wall-mounted air conditioner, a ceiling-mounted air conditioner or a window-mounted air conditioner. The air conditioner 100 can achieve self-cleaning, and the self-cleaning method is mainly divided into three stages: monitoring stage, dust removal stage and dust collection stage.

[0061] Please continue reading Figure 1 During the monitoring phase, a sensor 20 is provided at the edge of the air guide plate 60 of the air conditioner 100. The sensor 20 may be a PM2.5 sensor 20, a dust sensor 20, an infrared dust particle sensor 20, or a micro infrared dust particle sensor 20. When the air conditioner 100 is normally turned on and operated, the air guide plate 60 is opened, the sensor 20 is powered on, the indicator light is normally lit green, and the sensor 20 starts to detect the content of particulate matter in the flowing air blown out from the air conditioner 100.

[0062] If the content of particulate matter is greater than or equal to a preset value, the processor controls the color of the indicator light to change from green to red.

[0063] When the air conditioner 100 is turned on for three consecutive times, and the content of particulate matter obtained by the sensor 20 each time is greater than or equal to the preset value, the air conditioner 100 automatically turns on the dust removal mechanism 30. The dust removal mechanism 30 includes a motor 31 and a surface acoustic wave filter 32.

[0064] Please continue reading Figure 2 In the dust removal stage, when the processor of the air conditioner 100 detects that the content of particulate matter is greater than or equal to a preset value, the air guide plate 60 is closed, the compressor is stopped, and only the motor 31 rotates. At this time, the surface acoustic wave filter 32 works, and the audio of the motor 31 is received and filtered by the surface acoustic wave filter 32. The surface acoustic wave filter 32 then filters out the sound in the frequency range of 60 to 120 Hz and amplifies it to vibrate the particulate matter in the accommodation space of the air conditioner 100.

[0065] At this time, the dust removal mechanism 30 emits a large sound wave to vibrate the dust impurities and other particles attached to the internal structure of the air conditioner 100, so that the dust impurities and other particles that are vibrated out float in the air in the accommodation space again. The dust removal mechanism 30 stops working after vibrating for 3 minutes, and the particles can be deposited on the dust collection mechanism 50 due to the neutralizing effect of their own gravity.

[0066] Please continue reading Figure 3 During the dust collection stage, while the dust removal mechanism 30 is working, the processor is used to control the transmission structure of the dust box on the bottom 11 of the air conditioner 100 to be energized, and the dust box is ejected to the air outlet.

[0067] When the dust removal mechanism 30 stops working for a period of time, the transmission structure of the dust box on the bottom 11 of the air conditioner 100 is powered on again, the dust box is retracted into the accommodating space, the air conditioner 100 ends the self-cleaning function and resumes normal operation.

[0068] After the dust collection stage is over, the motor 31 is powered on again and the sensor 20 on the air guide plate 60 continues to work. If the content of particulate matter still exceeds the standard, the dust removal stage is entered again until the content of particulate matter is less than the preset value. If the content of particulate matter is reduced to less than the preset value, the color of the indicator light turns back to green, the self-cleaning process of the air conditioner 100 ends, the compressor starts, and the air conditioner 100 automatically resumes normal operation.

[0069] See also Figure 4 , Figure 4 A schematic flow chart of a self-cleaning method provided in an embodiment of the present application. An embodiment of the present application provides a self-cleaning method, which is applied to the above-mentioned air conditioner 100. The self-cleaning method includes the following steps.

[0070] S1. Detect particles in the flowing air blown out of the air outlet.

[0071] S2. If the content of the particulate matter is greater than or equal to a preset value, the dust removal mechanism 30 is turned on.

[0072] For example, the sensor 20 is a PM2.5 sensor 20, which can detect the content of particulate matter in the flowing air blown out from the air outlet. The preset value can be 10 micrograms / cubic meter. If the content of particulate matter in the flowing air blown out from the air outlet detected by the sensor 20 is greater than or equal to 10 micrograms / cubic meter, the dust removal mechanism 30 is turned on. In this example, the preset value of 10 micrograms / cubic meter is only for illustration, and the preset value can also be other values, such as 4 micrograms / cubic meter, 5 micrograms / cubic meter, 6 micrograms / cubic meter, 7 micrograms / cubic meter, 8 micrograms / cubic meter or 9 micrograms / cubic meter.

[0073] Of course, the particulate matter may be dust, and the sensor 20 may also be a dust sensor or an infrared dust particle sensor for detecting the dust content.

[0074] As described above, the quality of the air blown out of the air outlet is detected by the sensor 20 to indirectly obtain the dust condition on the surface of the structure in the accommodation space, and then the dust removal mechanism 30 can remove the dust on the surface of the structure to realize the self-cleaning function of the air conditioner 100.

[0075] In some embodiments, the air conditioner 100 further includes an indicator 40 , which is disposed on an outer surface of the housing 10 , and the indicator has different states.

[0076] The self-cleaning method further includes comparing the relationship between the content of the particulate matter and the preset value, and when the content of the particulate matter is greater than or equal to the preset value, the indicator 40 is controlled to be in the first state, and when the content of the particulate matter is less than the preset value, the indicator 40 is controlled to be in the second state. The first state is different from the second state, and is used to respectively indicate the relationship between the content of the particulate matter and the preset value.

[0077] For example, the indicator 40 is an indicator light, and the indicator light has different colors to indicate different states, such as the indicator light is red in the first state and green in the second state. When the indicator light presents different colors, the user can intuitively know the degree of dust and impurities accumulation inside the air conditioner 100. The user can also issue a dust removal command through the remote control, and the air conditioner 100 drives the dust removal mechanism 30 after receiving the dust removal command from the remote control to achieve manual dust removal.

[0078] When the indicator 40 is an indicator light, the indicator light may be a breathing light. The soft light state presented by the breathing light can reduce the light influence and interference on the user's sleep at night.

[0079] For another example, the indicator 40 is a display panel, and the display content of the display panel points to different states. For example, when the display panel displays “dirty”, it is the first state of the indicator 40 ; when the display panel displays “clean”, it is the second state of the indicator 40 .

[0080] It is worth noting that the indicator 40 provided in the embodiment of the present application is an indicator light or a display panel for illustrative purposes only. If there are other structures or methods that can enable the user to intuitively or relatively intuitively know the degree of dust and impurity accumulation inside the air conditioner 100, they are all within the protection scope of the embodiment of the present application.

[0081] In some embodiments, in order to reduce the frequent self-start of the dust removal mechanism 30, so as to save energy and reduce noise, the self-cleaning method further includes: controlling the sensor 20 to obtain particulate matter in the flowing air blown out of the air outlet each time the air conditioner 100 is turned on. When the air conditioner 100 is turned on multiple times and the content of particulate matter obtained by the sensor 20 each time is greater than or equal to the preset value, the dust removal mechanism 30 is turned on.

[0082] The air conditioner 100 is turned on multiple times means that the number of times it is turned on is greater than or equal to 2 times. For example, the number of times the air conditioner 100 is turned on is 3 times. When the air conditioner 100 is turned on for 3 consecutive times, and the content of particulate matter obtained by the sensor 20 each time is greater than or equal to the preset value, the air conditioner 100 automatically turns on the dust removal mechanism 30.

[0083] Of course, the user can set the detection method by himself, and can set the air conditioner 100 to be turned on 1 time, 2 times, 4 times or 5 times, so as to adjust the sensitivity of the air conditioner 100 to the content of particulate matter in the accommodation space, thereby saving energy consumption and reducing noise.

[0084] In some embodiments, when the dust removal mechanism 30 is turned on, the self-cleaning method further includes calculating the working time of the dust removal mechanism 30; when the working time of the dust removal mechanism 30 reaches a first time period, the dust removal mechanism 30 is turned off.

[0085] The first time period may be 2 to 10 minutes, for example 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes or 9 minutes.

[0086] The dust removal mechanism 30 emits a large sound wave to vibrate the dust impurities and other particles attached to the internal structure of the air conditioner 100, so that the dust impurities and other particles that are vibrated out float in the air in the accommodation space again. After the dust removal mechanism 30 stops working after vibrating for 3 minutes, the particles can be deposited on the dust collection mechanism 50 due to the neutralizing effect of their own gravity.

[0087] In some cases, after turning off the dust removal mechanism 30, the self-cleaning method also includes again obtaining the content of particulate matter in the flowing air blown out from the air outlet detected by the sensor 20; if the content of particulate matter is greater than or equal to a preset value, the dust removal mechanism 30 is turned on again until the content of particulate matter is less than the preset value.

[0088] In some embodiments, the air conditioner 100 further includes a dust collecting mechanism 50, the dust collecting mechanism 50 includes a dust collecting box and a transmission structure, and the transmission structure is respectively connected to the dust collecting box and the housing 10. The self-cleaning method includes: if the content of particulate matter is greater than or equal to a preset value, controlling the transmission structure to move to drive the dust collecting box to be located at the air outlet; when the dust removal mechanism 30 is closed, calculating the closing time of the dust removal mechanism 30, and when the closing time of the dust removal structure is a second time period, controlling the transmission structure to drive the dust collecting box to move into the accommodation space.

[0089] The integrated mechanism may be disposed at the bottom 11 of the air conditioner 100 to facilitate receiving particles deposited by gravity.

[0090] The transmission structure can be a clockwork spring.

[0091] The second time period may be 2 to 10 minutes, for example 2 minutes, 3 minutes, 4 minutes, 5 minutes, 6 minutes, 7 minutes, 8 minutes or 9 minutes.

[0092] While the dust removal mechanism 30 is working, the transmission structure for controlling the dust box on the bottom 11 of the air conditioner 100 is energized, and the dust box is ejected to the air outlet.

[0093] When the dust removal mechanism 30 stops working for a period of time, the transmission structure of the dust box on the bottom 11 of the air conditioner 100 is powered on again, the dust box is retracted into the accommodating space, the air conditioner 100 ends the self-cleaning function and resumes normal operation.

[0094] In some cases, before the transmission structure is controlled to drive the dust box to move into the accommodation space and after the dust removal structure is closed for a second period of time, the self-cleaning method further includes obtaining the content of particulate matter in the flowing air blown out of the air outlet detected by the sensor 20 again; if the content of particulate matter is greater than or equal to a preset value, the dust removal mechanism 30 is turned on again until the content of particulate matter is less than the preset value, at which time the dust box is retracted into the accommodation space, the air conditioner 100 ends the self-cleaning function, and resumes normal operation. In this case, multiple transmissions of the integrated mechanism can be avoided, thereby improving the dust removal efficiency of the air conditioner 100.

[0095] In some embodiments, the air conditioner 100 further includes an air guide plate 60, which is located at the air outlet, connected to the housing 10, and the sensor 20 is disposed on the air guide plate 60. It is understandable that since the flowing air blown out from the air outlet passes through the air guide plate 60, the sensor 20 is disposed on the air guide plate 60 to improve the detection efficiency of the sensor 20.

An embodiment of the present application provides an electronic device 200, including a memory 21, a processor 22, and a computer program stored in the memory 21 and executable on the processor 22. When the processor 22 executes the program, the self-cleaning method described above is implemented. The electronic device 200 is not only the air conditioner 100 in the above embodiment, but also other electrical enclosed spaces with similar principles, such as the sonic cleaning method in the engine compartment of a car.

[0097] An embodiment of the present application provides a non-temporary computer-readable storage medium on which a computer program is stored. When the computer program is executed by a processor, the self-cleaning method as described above is implemented.
