[0023] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0024] The embodiments of the present application provide an air conditioner and a self-cleaning method, the air conditioner can realize self-cleaning, which will be described in detail in combination with the drawings.

[0025] Please refer to Figure 1 and Figure 2 , Figure 1A first structure diagram of an air conditioner provided by an embodiment of the present application, Figure 2 A second structure diagram of an air conditioner provided by an embodiment of the present application.

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

[0027] The shell 10 has an air outlet and a containing space, and the air outlet is in communication with the containing space. The shell 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 arranged at the air outlet and can detect particulate matter in the flowing air blown out from the air outlet.

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

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

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

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

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

[0034] Of course, the particulate matter can be dust and impurities, and the sensor 20 can also be a dust sensor or an infrared dust particle sensor or a micro infrared dust particle sensor, which is used to detect the content of the dust.

[0035] The quality of the air blown out of the air outlet is detected by the sensor 20, so as to indirectly obtain the dust condition of the structural surface in the containing space, and the dust removal mechanism 30 can remove the dust on the structural surface, so as 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 that installing a mechanical cleaning device for automatically cleaning the filter screen or the evaporator in the air conditioner 100 causes a large space occupation in the indoor unit of the air conditioner 100, a limited cleaning range, and easy damage, etc., please refer to Figure 2 The dust removal mechanism 30 in the embodiment of the 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, and realizes the function of acoustic wave dust removal, so as to make the particulate matter in the containing space vibrate. The function of acoustic wave dust removal refers to using the wave characteristics of the acoustic wave to vibrate the particulate matter such as dust impurities attached to the structural surface in the containing space, so that the particulate matter falls off from the structural surface.

[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 and amplifies the sound in the frequency range of 60 to 120 Hz, so as to vibrate the particulate matter in the containing space of the air conditioner 100, and make the particulate matter fall off from the structural surface.

[0038] The motor 31 is a fan motor for driving the 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. By using the fan motor 31 of the air conditioner 100 as a sound wave generator, and amplifying the low-frequency sound through the surface acoustic wave filter 32, the particulate matter attached to the structure of the indoor unit of the air conditioner 100 is vibrated and falls off, and the dust removal range is more comprehensive and does not consume more energy.

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

[0040] The processor is configured to compare the content of the particulate matter with 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 a first state, and when the content of the particulate matter is less than the preset value, the indicator 40 is controlled to be in a second state. The first state and the second state are different, and are used to respectively indicate the relationship between the content of the particulate matter and the preset value.

[0041] For example, the indicator 40 is an indicator light, and different colors of the indicator light indicate different states. For example, the first state is indicated by a red indicator light, and the second state is indicated by a green indicator light. When the indicator light presents different colors, the user can intuitively know the accumulation degree of dust and other particulate matters inside the air conditioner 100. The user can also issue a dust removal instruction through the remote controller, and the processor of the air conditioner 100 drives the dust removal mechanism 30 to achieve manual dust removal after receiving the dust removal instruction of the remote controller.

[0042] When the indicator 40 is an indicator light, the indicator light can be a breathing light. The soft light state of 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 different display contents of the display panel indicate different states. For example, when the display panel displays “dirty”, it is the first state of the indicator 40; and 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 be performed to indicate different degrees of cleanliness or dirtiness.

[0044] It should be noted that the indicator 40 provided in the embodiments of the present application is only an example, and if other structures or methods can enable the user to intuitively or more intuitively know the accumulation degree of dust and other particulate matters inside the air conditioner 100, they are also within the protection scope of the embodiments of the present application.

[0045] In some embodiments, in order to reduce the frequent self-starting of the dust removal mechanism 30, save energy consumption, and reduce noise, the processor is further configured to: control the sensor 20 to obtain the content of particulate matters in the flowing air blown out of the air outlet each time the air conditioner 100 is turned on. When the number of times of turning on the air conditioner 100 is multiple times, and the content of particulate matters obtained by the sensor 20 each time is greater than or equal to a preset value, the dust removal mechanism 30 is started.

[0046] The number of times of turning on the air conditioner 100 is multiple times, which means that the number of times is greater than or equal to 2. For example, the number of times of turning on the air conditioner 100 is 3. In the case of continuously turning on the air conditioner 100 for 3 times, the content of particulate matters obtained by the sensor 20 each time is greater than or equal to the preset value, and the dust removal mechanism 30 of the air conditioner 100 is automatically started.

[0047] Of course, the user can set the detection mode by himself, and can set the number of times of turning on the air conditioner 100 to 1, 2, 4, or 5, to adjust the sensitivity of the air conditioner 100 to the content of particulate matters in the accommodation 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 configured to: calculate the working time of the dust removal mechanism 30; and turn off the dust removal mechanism 30 when the working time of the dust removal mechanism 30 reaches a first time period.

[0049] The first time period can 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 and other particulate matters attached to the internal structure of the air conditioner 100, so that the vibrated dust and other particulate matters float in the air in the accommodation space again. After the dust removal mechanism 30 stops working after 3 minutes of vibration, the particulate matters can deposit on the dust collection mechanism 50 due to the action of their own gravity.

[0051] In some cases, after the dust removal mechanism 30 is turned off and the first time period is elapsed, the processor is further configured to: again acquire the content of the particulate matters in the flowing air blown out of the air outlet detected by the sensor 20; and again turn on the dust removal mechanism 30 until the content of the particulate matters is less than the preset value, if the content of the particulate matters is greater than or equal to the preset value.

[0052] In some embodiments, referring to Figure 3 , Figure 3 A third structure diagram of the air conditioner provided by the embodiments of the present application is provided: Fig. (1) is a pop-up state of the integrated box of the air conditioner, and Fig. (2) is a retracted state of the integrated box of the air conditioner. The air conditioner 100 further comprises a dust collection mechanism 50, which comprises a dust collection box and a transmission structure connected with the dust collection box and the shell 10 respectively. The processor is electrically connected with the transmission structure. The processor is configured to: control the transmission structure to move to drive the dust collection box to be located at the air outlet if the content of the particulate matters is greater than or equal to the preset value; and calculate the closing time of the dust removal mechanism 30 when the dust removal mechanism 30 is turned off, and control the transmission structure to drive the dust collection box to move into the accommodation space when the closing time of the dust removal mechanism 30 reaches a second time period.

[0053] The integrated mechanism can be arranged at the bottom 11 of the air conditioner 100, which is convenient for receiving the particulate matters deposited due to gravity.

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

[0055] The second time period can 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] When the dust removal mechanism 30 is working, the processor is configured to control the transmission structure of the dust collection box on the bottom 11 of the air conditioner 100 to be powered on, and the dust collection box is popped out to the air outlet.

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

[0058] In some cases, before the control transmission structure drives the dust collection box to move into the containing space and the dust removal mechanism 30 is closed for a second time period, the processor is further configured to acquire 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 started again until the content of particulate matter is less than the preset value, at which time the processor controls the dust collection box to be retracted into the containing space, the air conditioner 100 ends the self-cleaning function, and returns to the normal running state. In this case, the transmission of the dust removal mechanism can be avoided multiple times, and the dust removal efficiency of the air conditioner 100 is improved.

[0059] In some embodiments, the air conditioner 100 further comprises a deflector 60, the deflector 60 is located at the air outlet, the deflector 60 is connected with the shell 10, and the sensor 20 is arranged on the deflector 60. Optionally, the sensor 20 is arranged on the edge of the deflector 60. It can be understood that since the flowing air blown out of the air outlet passes through the deflector 60, the detection efficiency of the sensor 20 can be improved by arranging the sensor 20 on the deflector 60.

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

[0061] Please continue to refer to Figure 1 For the monitoring stage, the edge of the deflector 60 of the air conditioner 100 is provided with a sensor 20, which can be a PM2.5 sensor 20, a dust sensor 20 or an infrared dust particle sensor 20 or a micro infrared dust particle sensor 20. When the air conditioner 100 is normally started and runs, the deflector 60 is opened, the sensor 20 is powered on and works, the indicator light normally lights up green, and the sensor 20 starts to detect the content of particulate matter in the flowing air blown out of 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] In the case of starting the air conditioner 100 for 3 times in succession, the content of particulate matter obtained by the sensor 20 each time is greater than or equal to the preset value, and then the dust removal mechanism 30 of the air conditioner 100 is automatically started. The dust removal mechanism 30 comprises a motor 31 and a surface acoustic wave filter 32.

[0064] Please continue to refer toFigure 2 For the dust removal stage, the processor of the air conditioner 100 detects that the content of particulate matter is greater than or equal to a preset value, and then the air deflector 60 is closed and the compressor is stopped, and only the motor 31 rotates. At this time, the surface acoustic wave filter 32 works, the audio of the motor 31 rotation is received by the surface acoustic wave filter 32 and filtered, and then the sound in the frequency range of 60 to 120 Hz is filtered out and amplified by the surface acoustic wave filter 32 to vibrate the particulate matter in the air conditioner 100.

[0065] At this time, the dust removal mechanism 30 emits a larger sound wave to vibrate the particulate matter such as dust and impurities attached to the internal structure of the air conditioner 100, so that the vibrated particulate matter such as dust and impurities floats again in the air in the accommodation space. The dust removal mechanism 30 stops working after 3 minutes of vibration, and the particulate matter can be deposited on the dust collection mechanism 50 due to the action of its own gravity.

[0066] Please continue to refer to Figure 3 For the dust collection stage, the dust removal mechanism 30 works at the same time, and the processor is used to control the transmission structure of the dust collection box on the bottom 11 of the air conditioner 100 to be powered on, and the dust collection 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 collection box on the bottom 11 of the air conditioner 100 is powered on again, and the dust collection box is retracted into the accommodation space, and the air conditioner 100 ends the self-cleaning function and returns to the normal operating state.

[0068] After the dust collection stage, the motor 31 is powered on and operated again, and the sensor 20 on the air deflector 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 changes back to green, the self-cleaning process of the air conditioner 100 ends, the compressor starts, and the air conditioner 100 automatically returns to normal operation.

[0069] Please refer to Figure 4 , Figure 4 The flowchart of the self-cleaning method provided by the embodiment of the application. The embodiment of the application provides a self-cleaning method applied to the air conditioner 100. The self-cleaning method comprises the following steps.

[0070] S1, detecting particulate matter in the flowing air blown out of the air outlet.

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

[0072] For example, the sensor 20 is a PM2.5 sensor 20, which is capable of detecting the content of particulate matters in the flowing air blown out of the air outlet. The preset value can be 10 μg / m3. If the content of particulate matters in the flowing air blown out of the air outlet detected by the sensor 20 is greater than or equal to 10 μg / m3, the dust removal mechanism 30 is started. In this example, the preset value of 10 μg / m3 is only for illustration, and the preset value can also be other values, such as 4 μg / m3, 5 μg / m3, 6 μg / m3, 7 μg / m3, 8 μg / m3, or 9 μg / m3.

[0073] Of course, the particulate matters can be dust, and the sensor 20 can also be a dust sensor or an infrared dust sensor for detecting the content of dust.

[0074] In this way, the quality of the air blown out of the air outlet is detected by the sensor 20, so as to indirectly obtain the dust condition of the structural surface in the accommodation space, and the dust removal mechanism 30 can remove the dust on the structural surface, so as to realize the self-cleaning function of the air conditioner 100.

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

[0076] The self-cleaning method further comprises comparing the content of the particulate matters with the preset value, controlling the indicator 40 to be in the first state when the content of the particulate matters is greater than or equal to the preset value, and controlling the indicator 40 to be in the second state when the content of the particulate matters is less than the preset value. The first state and the second state are different, and are used to respectively indicate the relationship between the content of the particulate matters 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 first state is that the color of the indicator light is red, and the second state is that the color of the indicator light is green. When the indicator light presents different colors, the user can intuitively know the accumulation degree of dust impurities inside the air conditioner 100. The user can also issue a dust removal instruction through a remote controller, and the air conditioner 100 drives the dust removal mechanism 30 after receiving the dust removal instruction of the remote controller, so as to realize manual dust removal.

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

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

[0080] It should be noted that the indicator 40 provided by the embodiments of the present application is a light indicator or a display panel, which is only an example. If other structures or methods can enable the user to intuitively or more intuitively know the dust accumulation degree inside the air conditioner 100, they are also within the protection scope of the embodiments of the present application.

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

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

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

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

[0085] The first time period can 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 larger sound wave to vibrate the dust and other particulate matters attached to the internal structure of the air conditioner 100, so that the vibrated dust and other particulate matters float in the air in the accommodation space again. After the dust removal mechanism 30 stops working after vibrating for 3 minutes, the particulate matters can deposit on the dust collecting mechanism 50 due to the action of their own gravity.

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

[0088] In some embodiments, the air conditioner 100 further comprises a dust collection mechanism 50, which comprises a dust collection box and a transmission structure connected with the dust collection box and the shell 10 respectively. The self-cleaning method comprises: if the content of particulate matter is greater than or equal to a preset value, controlling the transmission structure to move the dust collection box to the air outlet; when the dust removal mechanism 30 is closed, calculating the closing duration of the dust removal mechanism 30, and after the closing duration of the dust removal mechanism 30 is the second time period, controlling the transmission structure to move the dust collection box into the containing space.

[0089] The integrated mechanism can be arranged at the bottom 11 of the air conditioner 100, which is convenient for collecting particulate matter deposited due to gravity.

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

[0091] The second time period can 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] When the dust removal mechanism 30 is working, the transmission structure for controlling the dust collection box on the bottom 11 of the air conditioner 100 is powered on, and the dust collection box is ejected to the air outlet.

[0093] After the dust removal mechanism 30 stops working for a period of time, the transmission structure of the dust collection box on the bottom 11 of the air conditioner 100 is powered on again, the dust collection box is retracted into the containing space, and the air conditioner 100 ends the self-cleaning function and returns to the normal operating state.

[0094] In some cases, before controlling the transmission structure to move the dust collection box into the containing space and after the closing duration of the dust removal mechanism 30 is the second time period, the self-cleaning method further comprises: again acquiring 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 started again until the content of particulate matter is less than the preset value, at which time the dust collection box is retracted into the containing space, and the air conditioner 100 ends the self-cleaning function and returns to the normal operating state. In this case, the integrated mechanism can be driven multiple times to improve the dust removal efficiency of the air conditioner 100.

[0095] In some embodiments, the air conditioner 100 further comprises a deflector 60 located at the air outlet, the deflector 60 being connected with the shell 10, and the sensor 20 being arranged on the deflector 60. It can be understood that since the flowing air blown out of the air outlet passes through the deflector 60, arranging the sensor 20 on the deflector 60 can improve the detection efficiency of the sensor 20.

[0096] Please refer to Figure 5 , Figure 5The module schematic diagram of the electronic device provided by the embodiment of the present application is shown. The embodiment of the present application provides an electronic device 200, which comprises a memory 21, a processor 22, and a computer program stored in the memory 21 and capable of running on the processor 22. When the processor 22 executes the program, the self-cleaning method as described above is realized. The electronic device 200 is not only the air conditioner 100 in the above embodiment, but also other electrical closed spaces of similar principles, such as the sound wave dust cleaning method in the engine compartment of a car.

[0097] The embodiment of the present application provides a non-transitory computer readable storage medium, which stores a computer program. When the computer program is executed by a processor, the self-cleaning method as described above is realized.

[0098] The air conditioner 100 and the self-cleaning method provided by the embodiment of the present application are shown. The air conditioner 100 comprises a shell 10, a sensor 20, a dust removal mechanism 30, and a processor. The shell 10 has a containing space and an opening communicating with the containing space.
