[0048] In the related art, as the electronic dust collector works for a long time, more dust, hair and the like will adhere to the electronic dust collector, which seriously affects the subsequent dust removal ability of the electronic dust collector and may cause safety hazards such as fire. In order to eliminate the dust adsorbed on the electronic dust collector, manual disassembly and cleaning are often used, which is troublesome to operate and inconvenient to use.

[0049] According to the first aspect of the present invention, an air conditioner is provided. Figure 1 and Figure 2 , including a shell 10, an electronic dust collector 11, a fan 12, a cleaning component 13, a dust concentration sensor and a controller, etc.

[0050] The indoor unit of the air conditioner includes a housing 10, in which an air duct 100 is formed. The air duct 100 is formed with an air inlet 101 and an air outlet 102, wherein the air inlet 101 is used to receive fresh air from the outside, and the air outlet 102 is used to transport air to the room. A return air port 14 is also provided on the air duct 100, and the return air port 14 is used to receive indoor air. The return air port 14 is connected to the air outlet 102 through the air duct 100, and an indoor air circulation of return air port 14-air duct 100-air outlet 102-indoor-return air port 14 can be formed. A return air valve is provided at the return air port 14, and an air inlet valve can also be provided at the air inlet 101.

[0051] An electronic dust collector 11 is provided in the air duct 100, and the electronic dust collector 11 is located between the air inlet 101 and the air outlet 102. When the fresh air from the air inlet 101 flows through the electronic dust collector 11, the dust, hair and the like carried in the air will be adsorbed on the surface of the electronic dust collector 11, thereby improving the cleanliness of the air entering the room.

[0052] A fan 12 is provided in the air duct 100. Driven by the fan 12, outdoor air can enter the room along the air inlet 101, the air duct 100 and the air outlet 102, or indoor air can enter the room along the return air outlet 14, the air duct 100 and the air outlet 102. When the air passes through the air duct 100, dust or hair is filtered out by the electronic dust collector 11.

[0053] A cleaning component 13 is also provided in the air duct 100. The cleaning component 13 includes an ultrasonic nozzle 131 and a water supply pipeline connected to the ultrasonic nozzle 131. The cleaning component 13 is arranged adjacent to the electronic dust collector 11. Under the action of the water supply pipeline, the ultrasonic nozzle 131 sprays cleaning liquid to the electronic dust collector 11. The cleaning component 13 includes two electronic control components, one is the ultrasonic nozzle 131, and the other is a water pump of the water supply pipeline. Controlling the start and stop of the water pump can supply water to the ultrasonic nozzle 131 or cut off the water supply. Controlling the vibration frequency of the ultrasonic nozzle 131 can improve the cleaning effect of the cleaning liquid.

[0054] A dust concentration sensor is provided in the air duct 100, and the dust concentration sensor is located between the electronic dust collector 11 and the air outlet 102, and is used to detect the dust concentration of the air after the electronic dust collector 11 has removed the dust, and determine whether the dust removal capacity of the electronic dust collector 11 meets the standard and whether it needs to be cleaned according to the dust concentration.

[0055] The air conditioner provided in the embodiment of the present invention further includes a controller, which is electrically connected to the electronic dust collector 11, the fan 12, the cleaning component 13 and the dust concentration sensor, and is used to control the operation of the electronic dust collector 11, the fan 12 and the cleaning component 13 based on the dust concentration. The controller is configured to obtain the dust concentration in the air duct 100, and determine the air outlet state of the air outlet 102 according to the dust concentration and the pre-acquired air outlet state relationship; wherein the air outlet state includes a clean state and a dirty state; and when the air outlet state is a dirty state, the fan 12 and the electronic dust collector 11 are controlled to stop running, and the ultrasonic nozzle 131 of the cleaning component 13 is controlled to spray the cleaning liquid to the electronic dust collector 11 and continue for a first preset time; and when the air outlet state is a clean state, the fan 12 and the electronic dust collector 11 are controlled to operate according to a predetermined mode.

[0056] The air conditioner can spray cleaning liquid to the electronic dust collector 11 through the ultrasonic nozzle 131. The cleaning liquid impacts the surface of the electronic dust collector 11 in a high-frequency vibration manner, which can efficiently clean the adhesion on the surface of the electronic dust collector 11. It is easy to operate and has a good cleaning effect.

[0057] In some embodiments, the cleaning component 13 further includes a lifting mechanism 132, the ultrasonic nozzle 131 is connected to the lifting mechanism 132, and the lifting mechanism 132 is electrically connected to the controller.

[0058] See also Figure 1 and Figure 2 The lifting mechanism 132 can adjust the height of the ultrasonic nozzle 131 relative to the electronic dust collector 11, so that the ultrasonic nozzle 131 can clean different positions of the electronic dust collector 11, and can perform all-round cleaning on the electronic dust collector 11, which can achieve a better cleaning effect.

[0059] In some embodiments, the lifting mechanism 132 includes a bracket, a driver 133, a pulley, and a chain, etc. The base of the ultrasonic nozzle 131 is connected to the chain, and the position of the ultrasonic nozzle 131 relative to the electronic dust collector 11 can be adjusted under the action of the driver 133.

[0060] In some embodiments, there are two groups of cleaning components 13 , and the two groups of cleaning components 13 are respectively located on both sides of the electronic dust collector 11 .

[0061] See also Figure 1 The two independently controlled cleaning components 13 are respectively located on both sides of the electronic dust collector 11. The two cleaning components 13 can be located at the same height or at different heights. When the two cleaning components 13 are located at different heights, the electronic dust collector 11 can be cleaned multiple times in sequence. When the two cleaning components are located at the same height, the adhered matter can be impacted on both sides at the same time, thereby improving the cleaning effect on the adhered matter.

[0062] In some embodiments, a water collecting tray is provided at the bottom of the air duct 100, and the water collecting tray can collect the cleaning liquid sprayed by the ultrasonic nozzle 131. The water collecting tray is located at the lowest point in the air duct 100, so that all the cleaning liquid can flow into the water collecting tray. The air conditioner is also provided with a sewage pipeline, and a filter device is provided on the sewage pipeline, which can filter and discharge the cleaning liquid, and the filter device can be replaced or cleaned regularly.

[0063] In some embodiments, the air conditioner further includes a heating component 15, which is disposed at the air inlet 101, and the heating component 15 and the return air valve are electrically connected to the controller.

[0064] See also Figure 1The controller is electrically connected to the heating component 15 and the return air valve, and can control the operation of the heating component 15 and the opening and closing of the return air valve. The return air valve is closed, and then the heating component 15 and the fan 12 are opened, so that the air duct 100 can be dried by hot air, so as to avoid the accumulation of cleaning liquid in the air duct 100 to cause bacteria breeding, or to avoid the phenomenon of short circuit of electronic components, thereby improving the safety of the air conditioner.

[0065] In some embodiments, a primary filter 16 is disposed in the air duct 100 , and the primary filter 16 is disposed between the air inlet 101 and the electronic dust collector 11 .

[0066] See also Figure 1 A primary filter 16 is provided between the air inlet 101 and the electronic dust collector 11 in the air duct 100. Large particles in the air can be filtered by the primary filter 16, and then dust and hair in the air can be eliminated by the electronic dust collector 11, thereby improving the air filtering effect. The air inlet 101 and the return air outlet 14 are both located upstream of the primary filter 16 and the electronic dust collector 11. Whether it is fresh air entering the room or indoor air circulation, it can be filtered twice, and the air cleaning effect is better.

[0067] According to the second aspect of the present invention, the cleaning control method of the air conditioner is provided. Figure 3 ,include:

[0068] S100, obtaining dust concentration in the air duct, and determining the air outlet state of the air outlet according to the dust concentration and the pre-acquired air outlet state relationship; wherein the air outlet state includes a clean state and a dirty state.

[0069] It is understandable that a dust concentration sensor is provided in the air duct, and the dust concentration sensor is located between the electronic dust collector and the air outlet, and is used to detect the dust concentration in the air after the electronic dust collector has removed the dust, and determine whether the dust removal capacity of the electronic dust collector meets the standard and whether it needs to be cleaned based on the dust concentration. In order to ensure the quality of indoor air, a corresponding relationship between dust concentration and air outlet status can be set. For example, when the dust concentration is greater than the allowed concentration threshold, the air outlet status is in a dirty state, the dust removal capacity of the electronic dust collector decreases, and cleaning is required; when the dust concentration is less than or equal to the preset allowed concentration threshold, the air outlet status is in a clean state, the dust removal capacity of the electronic dust collector is strong, and cleaning is not required.

[0070] S210. When the air outlet state is dirty, the fan and the electronic dust collector are controlled to stop running, and the ultrasonic nozzle of the cleaning component is controlled to spray cleaning liquid to the electronic dust collector for a first preset time.

[0071] It is understandable that when the air outlet state is dirty, the dust removal capacity of the electronic dust collector is insufficient and the electronic dust collector needs to be cleaned. At this time, the fan and the electronic dust collector are controlled to stop running, and there is no longer flowing air in the air duct. The ultrasonic nozzle of the cleaning component is controlled to spray cleaning liquid to the electronic dust collector. Under the action of the high-frequency vibrating cleaning liquid, the adhered matter can be quickly removed from the surface of the electronic dust collector. In order to ensure the cleaning effect of the electronic dust collector, the working time of the ultrasonic nozzle lasts for the first preset time.

[0072] S220: When the air outlet state is a cleaning state, the fan and the electronic dust collector are controlled to operate according to a predetermined mode.

[0073] It is understandable that when the air outlet state is in a clean state, the dust removal effect of the electronic dust collector is better and no cleaning is required. Therefore, the fan and the electronic dust collector are controlled to operate according to a predetermined mode to maintain the normal fresh air or return air function of the air conditioner.

[0074] The air conditioner can spray cleaning liquid to the electronic dust collector through an ultrasonic nozzle. The cleaning liquid impacts the surface of the electronic dust collector in a high-frequency vibration manner, which can efficiently clean the adhesion on the surface of the electronic dust collector. It is easy to operate and has a good cleaning effect.

[0075] In some embodiments, the step of controlling the ultrasonic nozzle of the cleaning component to spray the cleaning liquid to the electronic dust collector for a first preset time period further includes:

[0076] S211. Obtain the real-time dust concentration in the air duct.

[0077] S212. When the real-time dust concentration is greater than a preset concentration threshold, the lifting mechanism is controlled to start and the position of the ultrasonic nozzle is adjusted until the real-time dust concentration is less than or equal to the preset concentration threshold or the number of times the lifting mechanism is started is greater than or equal to the preset number of times.

[0078] It is understandable that after the ultrasonic nozzle is started, a high-frequency vibrating cleaning liquid can be sprayed into the electronic dust collector, thereby cleaning the electronic dust collector. After a large amount of adhesion has accumulated on the surface of the electronic dust collector, if the real-time dust concentration is still high after cleaning, the entire electronic dust collector needs to be cleaned. At this time, the lifting mechanism is controlled to start and adjust the position of the ultrasonic nozzle. The distance moved by the lifting mechanism each time it is started is fixed, such as 3cm or 5cm, so the lifting mechanism needs to move multiple times to make the cleaning liquid sprayed by the ultrasonic nozzle cover the entire surface of the electronic dust collector. At each position, the ultrasonic nozzle runs for the first preset time. As the lifting mechanism moves, the dust concentration in the air gradually decreases. When the real-time dust concentration is less than or equal to the preset concentration threshold, the lifting mechanism and the ultrasonic nozzle can be controlled to stop running.

[0079] In some cases, as the lifting mechanism operates multiple times until the number of times the lifting mechanism is started is greater than or equal to the preset number of times, the ultrasonic nozzle has covered the entire surface of the electronic dust collector. If the real-time dust concentration meets the requirements at this time, it means that the cleaning effect is better; if the real-time concentration does not meet the requirements, it means that the dust concentration is not caused by the blockage of the electronic dust collector, and cleaning can also be stopped.

[0080] S213: When the real-time dust concentration is less than or equal to a preset concentration threshold, the fan and the electronic dust collector are controlled to operate in a predetermined mode.

[0081] It can be understood that when the real-time dust concentration is less than or equal to the preset concentration threshold, the dust removal effect of the electronic dust collector is better and no cleaning is required. Therefore, the fan and the electronic dust collector are controlled to operate according to the predetermined mode to maintain normal fresh air and return air functions of the air conditioner.

[0082] In some embodiments, the step of controlling the lifting mechanism to start and adjust the position of the ultrasonic nozzle until the real-time dust concentration is less than or equal to a preset concentration threshold or the number of times the lifting mechanism is started is greater than or equal to a preset number of times, further includes:

[0083] S230, controlling the return air valve to close, and controlling the heating component and the fan to operate for a second preset time.

[0084] It is understandable that after the electronic dust collector is cleaned by an ultrasonic nozzle, there is excess cleaning liquid on the surface of the electronic dust collector and in the air duct. If the electronic dust collector or other electrical components are turned on, a short circuit may occur, which may lead to a malfunction of the air conditioner indoor unit. Therefore, it is necessary to run the heating component and the fan for a second preset time to dry the air duct and the electronic components in the air duct, thereby improving the safety of the air conditioner.

[0085] S240, control the return air valve to open, and control the fan and the electronic dust collector to operate according to a predetermined mode.

[0086] After the air duct and the electronic components in the air duct are dried, the fan and the electronic dust collector can be controlled to operate according to a predetermined mode, so that the air conditioner can play a normal fresh air or return air function and ensure the air quality.

[0087] According to the third aspect of the present invention, the cleaning control device of the air conditioner is provided. Figure 4 ,include:

[0088] The acquisition module 301 is used to acquire the dust concentration in the air duct and determine the air outlet state of the air outlet according to the dust concentration and the pre-acquired air outlet state relationship; wherein the air outlet state includes a clean state and a dirty state.

[0089] The control module 302 is used to control the fan and the electronic dust collector to stop running when the air outlet state is a dirty state, and control the ultrasonic nozzle of the cleaning component to spray cleaning liquid to the electronic dust collector for a first preset time; and when the air outlet state is a clean state, control the fan and the electronic dust collector to operate according to a predetermined mode.

[0090] It should be noted that the above steps S100 to S220, as well as other steps, are only for the convenience of expression and do not constitute a time sequence limitation for each step in the cleaning control method of the air conditioner. In addition, some contents are described in detail in the cleaning control method of the air conditioner provided in the second aspect embodiment, and the contents in all the cleaning control methods of the air conditioner are also applicable to the cleaning control device of the air conditioner provided in the third aspect embodiment, and in order to avoid repetition, the cleaning control device of the air conditioner provided in the third aspect embodiment is not described in detail.

[0091] The air conditioner provided in accordance with the fourth aspect of the embodiment of the present invention comprises a memory, a processor and a computer program stored in the memory and executable on the processor, wherein when the processor executes the program, the steps of the cleaning control method for the air conditioner provided in accordance with the second aspect of the embodiment of the present invention are implemented.
