Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and more specifically, relates to an air conditioner. Background Art

[0002] With the popular use of air conditioners, it often occurs that air conditioners are used in closed rooms for a long time in summer. Therefore, the problem of air disinfection, sterilization and purification in closed rooms becomes more and more important.

[0003] At present, most air conditioners adopt self-cleaning modules and high-temperature sterilization modules to sterilize the inside of the air conditioner. However, for the sterilization of indoor air, to improve the overall air quality in the room and reduce the bacterial content in the indoor air, the existing sterilization and purification means used in air conditioners are relatively single, the sterilization effect is not ideal, and the indoor air cannot be thoroughly sterilized as a whole. Moreover, for the purification of indoor air by existing air conditioners, the bacterial content in the indoor air is not accurately detected, and targeted sterilization is not carried out according to the bacterial content.

[0004] At the same time, the existing sterilization methods of air conditioners do not combine with the control methods of air conditioners to improve the sterilization and purification effect, so the sterilization and purification effect is relatively poor.

[0005] Therefore, it is an urgent technical problem to be solved to develop an air conditioner that comprehensively uses various sterilization means for sterilization, and combines the detection of indoor air quality and the control method of the air conditioner to improve the indoor air quality.

In addition, the present invention provides examples of various specific processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0053] In this application, the air conditioner performs a refrigeration cycle by using a compressor, a condenser, an expansion valve, and an evaporator. The refrigeration cycle includes a series of processes involving compression, condensation, expansion, and evaporation to cool or heat an indoor space.

[0054] The low-temperature and low-pressure refrigerant enters the compressor, and the compressor compresses it into a refrigerant gas in a high-temperature and high-pressure state and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process. The expansion valve expands the high-temperature and high-pressure liquid-phase refrigerant formed in the condenser into a low-pressure liquid-phase refrigerant. The evaporator evaporates the refrigerant expanded in the expansion valve and returns the refrigerant gas in a low-temperature and low-pressure state to the compressor. The evaporator can achieve a refrigeration effect by using the latent heat of evaporation of the refrigerant to exchange heat with the material to be cooled. Throughout the cycle, the air conditioner can adjust the temperature of the indoor space.

[0055] The outdoor unit of the air conditioner refers to the part of the refrigeration cycle including the compressor and the outdoor heat exchanger. The indoor unit of the air conditioner includes the indoor heat exchanger, and the expansion valve can be provided in the indoor unit or the outdoor unit.

[0056] The indoor heat exchanger and the outdoor heat exchanger are used as condensers or evaporators. When the indoor heat exchanger is used as a condenser, the air conditioner operates in the heating mode; when the indoor heat exchanger is used as an evaporator, the air conditioner operates in the cooling mode.

[0057] Among them, the way the indoor heat exchanger and the outdoor heat exchanger are converted to be used as condensers or evaporators generally uses a four-way valve. For specific reference, please refer to the settings of conventional air conditioners, which will not be elaborated here.

[0058] The refrigeration working principle of the air conditioner is as follows: When the compressor works, the indoor heat exchanger (in the indoor unit, which is an evaporator at this time) is in an ultra-low pressure state. The liquid refrigerant in the indoor heat exchanger quickly evaporates and absorbs heat. The air blown by the indoor fan cools down after passing through the indoor heat exchanger coil and then blows into the room as cold air. After the refrigerant evaporates and vaporizes, it is pressurized by the compressor and condenses into a liquid in the high-pressure environment of the outdoor heat exchanger (in the outdoor unit, which is a condenser at this time), releasing heat. Through the outdoor fan, the heat is dissipated into the atmosphere. In this way, the refrigeration effect is achieved through such a cycle.

[0059] The heating working principle of the air conditioner is as follows: The gaseous refrigerant is pressurized by the compressor to become a high-temperature and high-pressure gas, enters the indoor heat exchanger (which is a condenser at this time), condenses and liquefies to release heat, becoming a liquid, and at the same time heats the indoor air, thereby achieving the purpose of raising the indoor temperature. The liquid refrigerant is depressurized by the throttling device and enters the outdoor heat exchanger (which is an evaporator at this time), evaporates and vaporizes to absorb heat, becoming a gas, and at the same time absorbs the heat of the outdoor air (the outdoor air becomes colder), becoming a gaseous refrigerant, and then enters the compressor again to start the next cycle.

[0060] Example 1. In this example, as Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 shown, in order to detect the bacterial content of the indoor air, a first bacteria detector 380 is provided.

[0061] Specifically, as Figure 5 shown, the first bacteria detector 380 is arranged outside the air outlet 310 of the indoor unit of the air conditioner.

[0062] In this example, as Figure 5 shown, in order to achieve the comprehensive sterilization of the indoor air by the air conditioner, a magnetic field generator 100 and a microwave emitter 200 are arranged inside the indoor unit of the air conditioner.

[0063] The first bacteria detector 380 is used to detect the indoor air. After the detected indoor bacterial content is greater than the set value, the magnetic field generator 100 or the microwave emitter 200 is turned on to sterilize the indoor air.

[0064] Sterilization is carried out by means of magnetism, that is, when the air flow cuts the magnetic induction lines during the flowing process, an induced current is generated, which can destroy the activity of bacteria or denature the proteins of bacteria, so as to achieve deep sterilization of the air and improve the sterilization effect on indoor air. At the same time, under the action of the potential difference of the magnetic field, when the air flow passes through the magnetic field, negative ions can be generated, and the negative ions can adsorb the micro dust and bacteria in the air, so as to further improve the sterilization and dust removal effects on the air.

[0065] When the magnetic field generator 100 is turned on alone, the magnetic field can sterilize by denaturing the bacterial proteins.

[0066] In order to improve the sterilization effect of magnetic sterilization and ensure that the air flow flowing out of the air conditioner indoor unit air outlet 310 all passes through the range covered by the magnetic field, in this embodiment, the magnetic field generator 100 is arranged on the lower side of the air conditioner indoor unit air outlet 310, so that the air flow flowing out of the air conditioner indoor unit air outlet 310 all passes through the action of the magnetic field for sterilization.

[0067] Specifically, the number of the magnetic field generators 100 is two, which are respectively located on both sides of the lower end of the air conditioner indoor unit air outlet 310. Thus, the magnetic field formed by the magnetic field generators 100 can cover the air flow path flowing towards the air conditioner indoor unit air outlet in the air conditioner indoor unit, so as to achieve the full coverage of the magnetic field for the air flow.

[0068] In addition to being able to kill bacteria by using the method of protein denaturation, the magnetic field can also generate negative ions for the bacteria that cannot be killed again, so as to adsorb the residual bacteria. After the negative ions adsorb the participating bacteria and flow out from the air conditioner indoor unit air outlet 310, after the negative ions combine with the bacteria, the combination will fall to the ground and remain for a long time, which is convenient for subsequent sterilization steps to carry out sterilization.

[0069] Sterilization is carried out by using the microwave principle, that is, by irradiating microwaves to generate heat so as to achieve the purpose of sterilization and disinfection. At the same time, by using the microwave principle, the bacteria in the air can also be decomposed and excited into separate factors. Thus, it is convenient for subsequent other sterilization methods to kill the bacteria.

[0070] In this embodiment, in order to make the microwaves cover the air conditioner indoor unit air return opening 320 as a whole, the number of the microwave emitters 200 is 4, and the 4 microwave emitters 200 are respectively arranged at the four corners of the air conditioner indoor unit air return opening 320.

[0071] Thus, when the indoor air flows through the air conditioner indoor unit air return opening 320, part of the bacteria are killed by the heat of the microwaves, and the other part of the residual bacteria can be fully separated from the air, which is convenient for subsequent sterilization methods to kill the bacteria.

[0072] In this embodiment, bacteria in the air flow passing through the air return opening 320 of the indoor unit of the air conditioner have been separated from the air, and the bacteria enter the indoor unit of the air conditioner along with the air flow.

[0073] During the process of turning on the microwave emitter 200 or the magnetic field generator 100, in order to ensure the gas flow rate through the air outlet 310 or the air return opening 320 of the indoor unit of the air conditioner during the operation of the microwave emitter 200 or the magnetic field emitter 100, so that a large amount or even all of the air in the room can flow through the air outlet 310 or the air return opening 320 of the indoor unit of the air conditioner within a short period of time. When the microwave emitter 200 or the magnetic field generator 100 is turned on, the horizontal swing blade 312 and the vertical swing blade 311 of the air outlet of the indoor unit of the air conditioner both maintain the maximum air outlet angle.

[0074] In this embodiment, among the gas flowing out of the air outlet 310 of the indoor unit of the air conditioner via the magnetic field generator 100, some bacteria are killed by the magnetic field, and there are still some bacteria adsorbed by negative ions.

[0075] Among the air flow flowing into the indoor unit via the microwave emitter 200 and the air return opening 320 of the indoor unit of the air conditioner, some bacteria are killed by the microwave, and there are still some bacteria separated from the air.

[0076] In this embodiment, the frequency of the electromagnetic wave emitted by the microwave emitter 200 is in the range of 300 to 300000 MHz.

[0077] In order to further improve the thoroughness of sterilization, in this embodiment, a negative ion generator 400 and a drug sterilization module 500 are further provided in the indoor unit of the air conditioner.

[0078] The first bacteria detector 380 is used to detect the indoor air. After the indoor bacteria content detected by the first bacteria detector 380 is greater than the set value, the negative ion generator 400 or the drug sterilization module 500 is turned on to sterilize the indoor air.

[0079] The negative ion generator 400 can release negative ions. The negative ions can combine with bacteria, causing the structure of the bacteria to change, realizing the transfer of the energy of the bacteria. The negative ions can make the protein of the bacteria produce a bipolar inversion, resulting in a decrease in the survival ability of the bacteria or the death of the bacteria. And because the negative ions have adsorption properties, the bacteria that are not killed in the air can be adsorbed by the negative ions and stay on the indoor floor for a long time after adsorption.

[0080] The drug sterilization module 500 can slowly release drugs into the indoor air to sterilize the bacteria adsorbed on the surface and the bacteria staying in the air.

[0081] The drugs released into the room via the drug sterilization module 500 can remain in the indoor environment for a long time, forming a long-term sterilization effect.

[0082] After the sterilization by the negative ion generator 400, the microwave emitter 200, and the magnetic field generator 100, the remaining bacteria are further sterilized by the drugs released by the drug sterilization module 500. And because the drug sterilization has a persistent effect, the indoor air can be fully sterilized.

[0083] In this embodiment, the negative ion generator 400 is arranged at the air outlet 310 of the indoor unit of the air conditioner. After the bacteria in the air flow are sterilized when flowing through the negative ion generator 400, the remaining bacteria can be adsorbed on the negative ions and deposited on the indoor floor.

[0084] In this embodiment, the drug sterilization module 500 is arranged at the air return opening 320 of the indoor unit of the air conditioner. The drugs released by the drug sterilization module 500 can flow along with the gas flowing into the air return opening 320 of the indoor unit of the air conditioner, flow through the indoor unit of the air conditioner, flow out through the air outlet 310 of the indoor unit of the air conditioner to the outside of the indoor unit of the air conditioner, and flow into the indoor environment.

[0085] During the process of the drug flowing along with the air flow, sterilization can be carried out. And after the drug flows into the indoor air along with the air flow, it can sterilize the indoor air for a long time. Thus, it has a very significant effect on the thorough sterilization of the indoor air.

[0086] During the working process of the negative ion generator 400 or the drug sterilization module 500, it is necessary to make the indoor air flow into the indoor unit of the air conditioner through the air return opening 320 of the indoor unit of the air conditioner and flow out to the indoor through the air outlet 310 of the indoor unit of the air conditioner, so that the indoor air can all pass through the action of the negative ion generator 400 and the action of the drug sterilization module 500. Thus, the unevenness of the indoor air quality can be avoided and the indoor air can be ensured to be all treated.

[0087] In this embodiment, during the period when the negative ion generator 400 is turned on, the vertical swing blade 311 at the air outlet of the indoor unit of the air conditioner swings at a uniform speed for several complete strokes between the maximum angle of the normal vertical louvers and the minimum angle of the normal vertical louvers during the normal operation of the air conditioner. The horizontal swing blade 312 at the air outlet of the indoor unit of the air conditioner swings at a uniform speed for several complete strokes between the minimum angle of the normal horizontal louvers and the maximum angle of the normal horizontal louvers during the normal operation of the air conditioner. Thus, it is ensured that the indoor air all passes through the action of the negative ion generator 400.

[0088] In this embodiment, during the period when the drug sterilization module 500 is turned on, the vertical swing blade 311 at the air outlet of the indoor unit of the air conditioner swings at a uniform speed for several complete strokes between the maximum angle of the vertical louver during normal operation of the air conditioner and the minimum angle of the vertical louver during normal operation of the air conditioner. The horizontal swing blade 312 at the air outlet of the indoor unit of the air conditioner swings at a uniform speed for several complete strokes between the minimum angle of the horizontal louver during normal operation of the air conditioner and the maximum angle of the horizontal louver during normal operation of the air conditioner. Thereby ensuring that the indoor air all passes through the action of the drug sterilization module 500.

[0089] During the period when the negative ion generator 400 and the drug sterilization module 500 are turned on simultaneously, the vertical swing blade 311 at the air outlet of the indoor unit of the air conditioner swings at a uniform speed for several complete strokes between the maximum angle of the vertical louver during normal operation of the air conditioner and the minimum angle of the vertical louver during normal operation of the air conditioner. The horizontal swing blade 312 at the air outlet of the indoor unit of the air conditioner swings at a uniform speed for several complete strokes between the minimum angle of the horizontal louver during normal operation of the air conditioner and the maximum angle of the horizontal louver during normal operation of the air conditioner. Thereby ensuring that the indoor air all passes through the sufficient action of the negative ion generator 400 or the drug sterilization module 500.

[0090] By arranging the negative ion generator 400 and the magnetic field generator 100 at the air outlet 310 of the indoor unit of the air conditioner, and arranging the drug sterilization module 500 and the microwave transmitter 200 at the air return opening 320 of the indoor unit of the air conditioner, and comprehensively using various sterilization methods to sterilize the indoor environment, the sterilization effect can be greatly improved and the air quality can be improved.

[0091] By setting the first bacteria detector 380, the bacteria content in the indoor air can be detected, and thus it can be judged whether sterilization is needed according to the bacteria content in the indoor air, making the sterilization more targeted.

[0092] In order to detect the bacteria content in the indoor unit of the air conditioner, a second bacteria detector 330 is arranged in the indoor unit of the air conditioner, and the second bacteria detector 330 is used to detect the bacteria content inside the indoor unit of the air conditioner.

[0093] In this embodiment, as Figure 7 、 Figure 8 、 Figure 9 shown, in order to realize the sterilization inside the indoor unit of the air conditioner, a self-cleaning module 340 and a high-temperature sterilization module 350 are arranged.

[0094] The self-cleaning module 340 and the high-temperature sterilization module 350 are respectively arranged on both sides of the heat exchanger of the indoor unit of the air conditioner.

[0095] The second bacteria detector 330 is arranged above the self-cleaning module 340 and the high-temperature sterilization module 350.

[0096] It is equivalent to the air flow flowing in from the return air outlet 320 of the air conditioner indoor unit. After being sterilized by the self-cleaning module 340 and the high-temperature sterilization module 350, it is detected. If the bacteria content in the air conditioner detected by the second bacteria detector is still greater than the set value, the self-cleaning module 340 or the high-temperature sterilization module 350 needs to be started again, or the self-cleaning module 340 and the high-temperature sterilization module 350 need to be started simultaneously.

[0097] In order to improve the sterilization effect of the self-cleaning module 340 on the air conditioner indoor unit, it is also necessary to cooperate with the control of the louvers of the air conditioner indoor unit.

[0098] Specifically, when the self-cleaning module 340 is separately turned on to sterilize the air conditioner indoor unit, the vertical louver 311 at the air outlet of the air conditioner indoor unit is in the extreme swing position, and the horizontal louver 312 at the air outlet of the air conditioner indoor unit is at the minimum angle set value of the self-cleaning horizontal louver.

[0099] Here, it should be noted that when the vertical louver 311 at the air outlet of the air conditioner indoor unit is in the extreme swing position, it means that the vertical louver 311 at the air outlet of the air conditioner indoor unit is completely closed. However, after the vertical louver 311 at the air outlet of the air conditioner indoor unit is completely closed, there are still relatively large gaps between adjacent vertical louvers 311 at the air outlet of the air conditioner indoor unit, which will not affect the air outlet of the air outlet 310 of the air conditioner indoor unit.

[0100] If the horizontal louver 312 at the air outlet of the air conditioner indoor unit is in the extreme swing position, that is, the horizontal louver at the air outlet of the air conditioner indoor unit is completely closed, then adjacent horizontal louvers 312 at the air outlet of the air conditioner indoor unit will be closed, which will affect the air outlet of the air outlet 310 of the air conditioner indoor unit. Therefore, at this time, the horizontal louver 312 at the air outlet of the air conditioner indoor unit is at the minimum angle set value of the self-cleaning horizontal louver, rather than the extreme swing position. Thus, the normal air outlet of the air outlet 310 of the air conditioner indoor unit is ensured.

[0101] In order to improve the sterilization effect of the high-temperature sterilization module 350 on the air conditioner indoor unit, it is also necessary to cooperate with the control of the louvers of the air conditioner indoor unit.

[0102] Compared with the operation of the self-cleaning module 340 in the air conditioner indoor unit, the high-temperature sterilization module 350 requires more gas flow.

[0103] Therefore, specifically, when the high-temperature sterilization module 350 is separately turned on to sterilize the indoor unit of the air conditioner, or when the high-temperature sterilization module 350 and the self-cleaning module 340 are simultaneously turned on to sterilize the indoor unit of the air conditioner, the vertical louvers 311 at the air outlet of the indoor unit of the air conditioner are at the minimum angle setting value of the vertical louvers for high-temperature sterilization, and the horizontal louvers 312 at the air outlet of the indoor unit of the air conditioner are at the minimum angle setting value of the horizontal louvers for high-temperature sterilization. Thus, it is ensured that there is sufficient air flow retained in the indoor unit of the air conditioner, avoiding the components in the indoor unit of the air conditioner from being shut down due to high temperature because the air flow cannot fully flow during the operation of the high-temperature sterilization module.

[0104] The minimum angle setting value of the self-cleaning horizontal louvers, the minimum angle setting value of the vertical louvers for high-temperature sterilization, and the minimum angle setting value of the horizontal louvers for high-temperature sterilization are all set as fixed values in the system of the air conditioner.

[0105] In this embodiment, during the operation of the self-cleaning module 340 or the high-temperature sterilization module 350, especially during the operation of the high-temperature sterilization module 350, in order to ensure the air circulation in the indoor unit of the air conditioner, the indoor unit heat exchanger 360 and the indoor unit fan 370 of the air conditioner are turned on.

[0106] In this embodiment, a reminder module is also provided, and after the microwave transmitter 200 and the magnetic field generator 100 are turned off, the reminder module emits a reminder sound.

[0107] Embodiment 2. In this embodiment, a method for sterilizing using the air conditioner in Embodiment 1 is involved.

[0108] In this embodiment, for the various sterilization methods mentioned in Embodiment 1, taking a sterilization sequence as an example, an explanation is given.

[0109] As Figure 1 、 Figure 2 shown, the first bacteria detector 380 detects the bacteria content in the indoor air. If the bacteria content in the indoor air is lower than the set value of the indoor bacteria content, then no sterilization module needs to be turned on, and there is no need to enter the sterilization mode. After an interval of T5, the first bacteria detector 380 detects the bacteria content in the indoor air again.

[0110] The first bacteria detector 380 detects the bacteria content in the indoor air. If the bacteria content in the indoor air is greater than the set value of the indoor bacteria content, then the negative ion generator 400 is turned on.

[0111] After the negative ion generator 400 operates for a time T2, the first bacteria detector 380 detects the bacteria content in the indoor air. If the bacteria content in the indoor air is lower than the set value of the indoor bacteria content, then the negative ion generator 400 is turned off. After an interval of T5, the first bacteria detector 380 detects the bacteria content in the indoor air again.

[0112] During the above-mentioned T2 time, the vertical louvers 311 at the air outlet of the indoor unit of the air conditioner swing at a uniform speed for at least one complete stroke between the maximum angle of the vertical louvers during normal operation of the air conditioner and the minimum angle of the vertical louvers during normal operation of the air conditioner. The horizontal louvers 312 at the air outlet of the indoor unit of the air conditioner swing at a uniform speed for several complete strokes between the minimum angle of the horizontal louvers during normal operation of the air conditioner and the maximum angle of the horizontal louvers during normal operation of the air conditioner.

[0113] If the bacterial content in the indoor air is greater than the set value of the indoor bacterial content, the negative ion generator 400 and the drug sterilization module 500 are turned on simultaneously. After T3 time, the first bacterial detector 380 detects the bacterial content in the indoor air. If the bacterial content in the indoor air is lower than the set value of the indoor bacterial content, the negative ion generator 400 is turned off and the drug sterilization module 500 is turned off. After an interval of T5 time, the first bacterial detector 380 detects the bacterial content in the indoor air again.

[0114] If the bacterial content in the indoor air is greater than the set value of the indoor bacterial content, the negative ion generator 400 and the drug sterilization module 500 are turned on simultaneously. After another T3 time, the first bacterial detector 380 detects the bacterial content in the indoor air. If the bacterial content in the indoor air is lower than the set value of the indoor bacterial content, the negative ion generator 400 is turned off and the drug sterilization module 500 is turned off. After an interval of T5 time, the first bacterial detector 380 detects the bacterial content in the indoor air again.

[0115] If the bacterial content in the indoor air is greater than the set value of the indoor bacterial content, the magnetic field generator 100 is turned on. After the magnetic field generator 100 is turned on for T1 time, the microwave transmitter 200 is turned on. After the microwave transmitter 200 is turned on for T7 time, the first bacterial detector 380 detects the bacterial content in the indoor air. If the bacterial content in the indoor air is lower than the set value of the indoor bacterial content, the magnetic field generator 100 is turned off and the microwave transmitter 200 is turned off.

[0116] If the bacterial content in the indoor air is greater than the set value of the indoor bacterial content, the microwave transmitter 200 and the magnetic field generator 100 continue to be turned on for T4 time and then the microwave transmitter 200 and the magnetic field generator 100 are turned off.

[0117] During the above-mentioned T1 time and T4 time, the horizontal swing blade 312 and the vertical swing blade 311 at the air outlet of the indoor unit of the air conditioner both maintain the maximum air outlet angle.

[0118] After all the sterilization devices are turned off, the horizontal swing blade 312 at the air outlet of the indoor unit of the air conditioner moves between the maximum angle and the minimum angle of the horizontal louvers during normal operation of the air conditioner; the vertical swing blade 311 at the air outlet of the indoor unit of the air conditioner moves between the maximum angle and the minimum angle of the vertical louvers during normal operation of the air conditioner. The prompt module emits a prompt sound to inform the user that the sterilization has been completed.

[0119] In this embodiment, the times of T1, T2, T3, and T4 are all short, generally within 10 minutes. The time of T7 is longer, generally greater than 30 minutes. The time of T5 is even longer and is determined according to the practical environment of the indoor unit of the air conditioner.

[0120] The opening sequence of the above-mentioned sterilization method can be adjusted according to specific needs, and only this example is used for illustration in this embodiment.

[0121] Embodiment 3, as Figure 3 、 Figure 4 shown, in this embodiment, the second bacteria detector 330 detects the bacteria content in the indoor unit of the air conditioner. If the indoor bacteria content detected by the first bacteria detector 330 is less than the set value, the sterilization mode is exited, and after an interval time T5, the detection is performed again.

[0122] If the bacteria content in the indoor unit of the air conditioner detected by the first bacteria detector 330 is greater than the set value, the self-cleaning module 340 is turned on, and the high-temperature sterilization module 350 is turned on.

[0123] After the self-cleaning module 340 and the high-temperature sterilization module 350 are turned on for a time T6, the second bacteria detector 330 detects the bacteria content in the indoor unit of the air conditioner. If the indoor bacteria content detected by the first bacteria detector 330 is less than the set value, the sterilization mode is exited, and after an interval time T5, the detection is performed again.

[0124] If the indoor bacteria content detected by the first bacteria detector 330 is greater than the set value, the self-cleaning module 340 is turned on, and the high-temperature sterilization module 350 is turned on.

[0125] Multiple cycles are performed until the indoor bacteria content detected by the first bacteria detector 330 is less than the set value, the sterilization mode is exited, and after an interval time T5, the detection is performed again.

[0126] Within the time T6, the heat exchanger of the indoor unit of the air conditioner and the indoor unit fan are turned on; the vertical louver 312 at the air outlet of the indoor unit of the air conditioner is in the extreme swing position; the horizontal louver 311 at the air outlet of the indoor unit of the air conditioner is at the minimum angle set value of the self-cleaning horizontal swing leaf.

[0127] After both the self-cleaning module 340 and the high-temperature sterilization module 350 are turned off, the horizontal swing leaf 311 at the air outlet of the indoor unit of the air conditioner moves between the maximum angle and the minimum angle of the normal operation horizontal louver of the air conditioner; the vertical swing leaf 312 at the air outlet of the indoor unit of the air conditioner moves between the maximum angle and the minimum angle of the normal operation vertical louver of the air conditioner.

[0128] When the indoor bacteria content detected by the first bacteria detector 330 is greater than the set value, it is also possible to only turn on the self-cleaning module 340 or the high-temperature sterilization module 350, or turn on the self-cleaning module 340 and the high-temperature sterilization module 350 successively, which is not limited here.

[0129] Embodiment 4. In this embodiment, the sterilization of the indoor unit of the air conditioner and the sterilization of the indoor air in Embodiment 2 and Embodiment 3 are carried out simultaneously. Through the circulation of the indoor air and the air in the indoor unit of the air conditioner, the progress of sterilization is promoted.

[0130] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in any one or more embodiments or examples in a suitable manner.

[0131] The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
