[0037] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be described below in combination with specific embodiments of the present application and corresponding drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0038] It is very important to reduce the microorganisms breeding in the pipeline of the air conditioner from directly entering the room. In order to reduce the microorganisms breeding in the pipeline of the air conditioner from directly entering the room as much as possible, in the related scheme, the way of the air conditioner to the microorganisms breeding in the pipeline of the air conditioner is mainly: ① opening the sterilization function of the air conditioner, and continuously sterilizing in the running process of the air conditioner; ② according to the running state of the air conditioner and the indoor environment state, the sterilization function of the air conditioner is switched. However, in these ways, on the one hand, electricity is wasted, and on the other hand, in the process of the air conditioner continuously blowing air, after the air quality of the air conditioner blowing air tends to be stable, the content of the microorganisms breeding in the pipeline of the air conditioner is less, and it is unnecessary to continuously sterilize. Therefore, it is imminent to research an economical, practical and obvious effect method for preventing the microorganisms aerosol carried by the residual air in the pipeline of the air conditioner from directly entering the room and being inhaled by the human body.

[0039] Research shows that the number of microorganisms aerosol contacted by the human body is more in the time period of 20s to 80s of the air conditioner starting stage, and the number of microorganisms aerosol contacted by the human body reaches the peak at the time point of 30s of the air conditioner starting stage, and then the number of microorganisms carried by the residual air in the air conditioner is small, and the influence on the human body is small. By using the characteristics, the scheme of the application provides a control method of the air conditioner, specifically a sterilization control method of the air conditioner, by combining the length of the pipeline in the air conditioner, the indoor environment temperature and humidity and the like, the angle of the air deflector, the air speed of the indoor fan and the like are controlled at the same time, the sterilization operation is performed on the residual air in the pipeline of the air conditioner initially sent when the air conditioner is started, the microorganisms aerosol carried by the residual air in the pipeline of the air conditioner can be effectively removed, the risk that the microorganisms breeding in the pipeline of the air conditioner enter the room and the indoor air is directly inhaled by the human body after the indoor air is directly inhaled by the human body is reduced, and the health of the human body is ensured.

[0040] According to the embodiments of the application, a control method of an air conditioner is provided, as shown in Figure 1 The control method of the air conditioner can include: an indoor unit of the air conditioner has an air outlet and a sterilization device; the sterilization device is arranged on the inner side of the air outlet, wherein the inner side of the air outlet is the inside of the air outlet along the air outlet direction of the air duct where the air outlet is located, and the outside of the air outlet is the outside of the air outlet. The control method of the air conditioner includes steps S110 to S140.

[0041] At step S110, after the air conditioner is powered on each time, the indoor environment temperature of the environment where the air conditioner is located is obtained, which is recorded as the current indoor environment temperature of the air conditioner; and the indoor environment humidity of the environment where the air conditioner is located is obtained, which is recorded as the current indoor environment humidity of the air conditioner.

[0042] At step S120, after each power-on of the air conditioner, it is determined whether the air conditioner is in a shutdown state. The shutdown state includes a standby state and a power-off state after power-on. Specifically, the shutdown state includes an air conditioner remote shutdown state and a power-off state. In the power-off state, the ordinary control board cannot time, and if timing is required, a special method can be used to maintain timing, such as adding a standby capacitor to the control board. The capacitor discharges slowly and can maintain the timing chip within one month. The power-off state is timed in this way.

[0043] At step S130, if it is determined that the air conditioner is in a shutdown state, the time during which the air conditioner is in the shutdown state is accumulated and timed according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner, to obtain an accumulated shutdown time, denoted as the current accumulated shutdown time of the air conditioner, and the current accumulated shutdown time of the air conditioner is stored.

[0044] In some embodiments, the specific process of accumulating and timing the time during which the air conditioner is in the shutdown state according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner to obtain an accumulated shutdown time, denoted as the current accumulated shutdown time of the air conditioner, in step S130, is described in the following example.

[0045] The following describes an embodiment of the method of the present application shown in Figure 2 The following describes an embodiment of the method of the present application shown in

[0046] At step S210, it is determined whether the current indoor environment temperature of the air conditioner is greater than a set temperature, and whether the current indoor environment humidity of the air conditioner is greater than a set humidity. The set temperature is, for example, 20°C, and the set humidity is, for example, 70%.

[0047] At step S220, if it is determined that the current indoor environment temperature of the air conditioner is greater than the set temperature, and that the current indoor environment humidity of the air conditioner is greater than the set humidity, the time during which the air conditioner is in the shutdown state is accumulated and timed to obtain a first accumulated shutdown time; the first accumulated shutdown time of the air conditioner is denoted as the current accumulated shutdown time of the air conditioner. The first accumulated shutdown time is, for example, time t1.

[0048] Step S230, if the current indoor environment temperature of the air conditioner is determined to be less than or equal to the set temperature, and / or the current indoor environment humidity of the air conditioner is determined to be less than or equal to the set humidity, the time for which the air conditioner is in the shutdown state is accumulated to obtain a second accumulated shutdown time; the second accumulated shutdown time of the air conditioner is recorded as the current accumulated shutdown time of the air conditioner. The second accumulated shutdown time is, for example, time t2.

[0049] Specifically, Figure 7 A flowchart of an embodiment of a control method for the timing logic of an air conditioner. As shown in the flowchart, the control method for the timing logic of the air conditioner includes: Figure 7

[0050] Step 11, after each power-on of the air conditioner, step 12 is performed.

[0051] Step 12, after each power-on of the air conditioner, the shutdown time of the air conditioner is started to be recorded, specifically, whether the air conditioner is in a shutdown state is determined: if yes, step 13 is performed to start recording the shutdown time of the air conditioner; otherwise, the shutdown time of the air conditioner is not recorded, and the shutdown time of the air conditioner is accumulated to be recorded after the next power-on of the air conditioner, specifically, whether the air conditioner is in a shutdown state is continuously determined, and the cycle is repeated. The on-off state of the air conditioner is known to the indoor unit control board of the air conditioner, and the operation of recording the time can also be performed by the control board.

[0052] Step 13, in the case where the air conditioner is in a shutdown state, whether the indoor environment temperature is greater than 20℃ and the indoor environment humidity is greater than 70% is determined: if yes, step 14 is performed, otherwise, step 15 is performed.

[0053] Step 14, when the indoor environment temperature is greater than 20℃ and the indoor environment humidity is greater than 70%, the accumulated time of the shutdown time of the air conditioner is recorded as time t1, and then step 16 is performed.

[0054] Step 15, when the indoor environment temperature is not greater than 20℃ or the indoor environment humidity is not greater than 70%, i.e., when the indoor environment temperature is less than 20℃ or the indoor environment humidity is less than 70%, the accumulated time of the shutdown time of the air conditioner is recorded as time t2, and then step 16 is performed.

[0055] Step 16, time t1 and time t2 are recorded in a storage unit, and in the case where the air conditioner is powered on and then shut down each time, time t1 and time t2 are continuously accumulated to be updated.

[0056] ​Wherein, only when the air conditioner is turned off, aerosol will be generated in the air conditioner, if the air conditioner has been turned on, air exchange has been carried out inside and outside the air conditioner. The time t1 and the time t2 are the shutdown time of the air conditioner, specifically, the shutdown time of the air conditioner after the air conditioner is powered on is accumulated, and the time from the shutdown to the next start-up is accumulated. For example: the air conditioner is turned off after being turned on, the air conditioner is powered off after a period of time, the air conditioner is powered on again after being powered off, and the air conditioner is still turned off after being powered on. In this case, the shutdown time of the air conditioner is recorded. As long as the air conditioner is turned off, the shutdown time of the air conditioner is always accumulated.

[0057] At step S140, if the air conditioner is turned on when the air conditioner is in the shutdown state, the opening and closing of the sterilization function of the air conditioner is controlled according to the current accumulated shutdown time of the air conditioner and the current running time after the air conditioner is turned on, so that when the sterilization function of the air conditioner is turned on, the pipeline inside the air conditioner is sterilized by the sterilization function of the air conditioner, so as to reduce the microbial content in the microbial aerosol carried by the residual air in the pipeline, reduce the microorganisms carried by the microbial aerosol, prevent the user from smelling odor after the air conditioner is turned on, and affect the user experience, and also reduce the microbial aerosol carried by the residual air in the pipeline in the air conditioner from entering the indoor to affect human health; wherein, it is determined that the sterilization function of the air conditioner needs to be turned on to perform sterilization action, so that the sterilization function of the air conditioner is turned on to perform sterilization action when the air conditioner is turned on, and the sterilization device is controlled to be turned on when the air conditioner is turned on. In the case of air outlet, sterilization is performed. When the accumulated shutdown time reaches the set shutdown time, the sterilization function needs to be turned on, but the sterilization action is performed when the air conditioner is blowing in the case of user remote control turning on the air conditioner, and the sterilization action is not performed in the case of air conditioner shutdown.

[0058] The scheme of the present application controls the angle of the air deflector, the wind speed of the indoor fan, etc. by combining the length of the pipeline inside the air conditioner, the indoor environment temperature and humidity, etc. When the air conditioner is turned on, the initial residual air in the pipeline inside the air conditioner is sterilized, and the sterilization operation is necessary and effective, thereby improving the user experience and ensuring human health. Therefore, the microorganisms carried by the microbial aerosol carried by the residual air in the pipeline inside the air conditioner can be greatly reduced, the user can prevent smelling odor when the air conditioner is just turned on, the user experience is improved, and human health is ensured.

[0059] In some embodiments, the specific process of controlling the opening and closing of the sterilization function of the air conditioner according to the current accumulated shutdown time of the air conditioner and the current running time after the air conditioner is turned on in step S140 is described below.

[0060] The following will be described in combination with Figure 3An embodiment flowchart of the method of the application shown in FIG. 1 is further used to illustrate the specific process of controlling the start and stop of the sterilization function according to the current cumulative shutdown time and the current running time of the air conditioner in step S140, which comprises steps S310 to S330.

[0061] In step S310, it is determined whether the current cumulative shutdown time of the air conditioner reaches the set cumulative shutdown time of the air conditioner.

[0062] In some embodiments, the current cumulative shutdown time of the air conditioner is the first cumulative shutdown time of the air conditioner or the second cumulative shutdown time of the air conditioner; the set cumulative shutdown time of the air conditioner is the first set cumulative shutdown time of the air conditioner or the second set cumulative shutdown time of the air conditioner; wherein, when the current cumulative shutdown time of the air conditioner is the first cumulative shutdown time of the air conditioner, the set cumulative shutdown time of the air conditioner is the first set cumulative shutdown time of the air conditioner; when the current cumulative shutdown time of the air conditioner is the second cumulative shutdown time of the air conditioner, the set cumulative shutdown time of the air conditioner is the second set cumulative shutdown time of the air conditioner. When the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner are different values, the set cumulative shutdown time of the air conditioner corresponding to the current cumulative shutdown time of the air conditioner (i.e. the set cumulative shutdown time of the air conditioner) is also a different value.

[0063] In step S310, it is determined whether the current cumulative shutdown time of the air conditioner reaches the set cumulative shutdown time of the air conditioner, which comprises any of the following determination cases:

[0064] The first determination case: if the current cumulative shutdown time of the air conditioner is the first cumulative shutdown time of the air conditioner, it is determined whether the current cumulative shutdown time of the air conditioner reaches the first set cumulative shutdown time of the air conditioner. The first set cumulative shutdown time of the air conditioner is, for example, 8 hours.

[0065] The second determination case: if the current cumulative shutdown time of the air conditioner is the second cumulative shutdown time of the air conditioner, it is determined whether the current cumulative shutdown time of the air conditioner reaches the second set cumulative shutdown time of the air conditioner. The second set cumulative shutdown time of the air conditioner is, for example, 72 hours.

[0066] The sterilization device of the air conditioner is arranged at the air outlet of the air conditioner. When the time t1 reaches 8 hours, the sterilization function is started when the air conditioner is turned on; when the time t2 reaches 72 hours, the sterilization function is started when the air conditioner is turned on.

[0067] Step S320, if it is determined that the current cumulative shutdown time of the air conditioner has reached the set cumulative shutdown time of the air conditioner, it is determined that the sterilization function of the air conditioner needs to be turned on to perform sterilization action, the sterilization function of the air conditioner is turned on to perform sterilization action when the air conditioner is turned on, and the current cumulative shutdown time of the air conditioner is cleared after the air conditioner performs sterilization action, and then returns to re-determine whether the air conditioner is in the shutdown state, and then, if it is re-determined that the air conditioner is in the shutdown state, the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner are re-determined, and the time when the air conditioner is in the shutdown state is re-counted to obtain the cumulative shutdown time, which is recorded as the current cumulative shutdown time of the air conditioner, and the current cumulative shutdown time of the air conditioner is stored. Wherein, the determination that the sterilization function of the air conditioner needs to be turned on to perform sterilization action, so as to turn on the sterilization function of the air conditioner to perform sterilization action when the air conditioner is turned on, comprises: controlling the sterilization device of the air conditioner to be turned on; in the case that the sterilization function of the air conditioner is turned on, using the sterilization function of the air conditioner to sterilize the pipeline in the air conditioner, so as to reduce the microbial content in the microbial aerosol carried by the residual air in the pipeline, reduce the microorganisms carried by the microbial aerosol, prevent the user from smelling odor after the air conditioner is turned on and affecting the user experience, and also reduce the microbial aerosol carried by the residual air in the pipeline in the air conditioner from entering the indoor to affect human health.

[0068] Step S330, if it is determined that the current cumulative shutdown time of the air conditioner has not reached the set cumulative shutdown time of the air conditioner, the on-off of the sterilization function of the air conditioner is controlled according to the current running time of the air conditioner, so that in the case that the sterilization function of the air conditioner is turned on, the sterilization function of the air conditioner is used to sterilize the pipeline in the air conditioner, so as to reduce the microbial content in the microbial aerosol carried by the residual air in the pipeline, reduce the microorganisms carried by the microbial aerosol, prevent the user from smelling odor after the air conditioner is turned on and affecting the user experience, and also reduce the microbial aerosol carried by the residual air in the pipeline in the air conditioner from entering the indoor to affect human health.

[0069] Specifically, Figure 8 The flowchart of an embodiment of the control method of the air conditioner's cleaning timing logic is shown in FIG. 8. As shown in FIG. 8, the control method of the air conditioner's cleaning timing logic comprises: Figure 8 The control method of the air conditioner's cleaning timing logic comprises:

[0070] Step 21: After the air conditioner is turned on, determine whether the cumulative time of the air conditioner's shutdown time has not reached the set cumulative time. If so, proceed to step 22 to control the opening and closing of the air conditioner's sterilization device according to the current running time of the air conditioner. Otherwise, control the air conditioner's sterilization device to turn on, so as to activate the air conditioner's sterilization function and sterilize the residual air in the pipes initially delivered by the air conditioner when it is turned on. Time t1 and time t2 are reset to zero and start timing again.

[0071] Step 22: Control the opening and closing of the air conditioner's sterilization device according to the current running time of the air conditioner.

[0072] In some embodiments, the specific process of controlling the start and stop of the sterilization function of the air conditioner according to the current running time of the air conditioner when the current cumulative shutdown time of the air conditioner has not reached the set cumulative shutdown time of the air conditioner in step S330 is described in the following exemplary description.

[0073] The following is combined with Figure 4 The flowchart shown is a schematic diagram of an embodiment of the method of the present invention that controls the start and stop of the sterilization function according to the current running time after the air conditioner is turned on. The specific process of controlling the start and stop of the sterilization function according to the current running time after the air conditioner is turned on in step S330 is further explained, including steps S410 to S430.

[0074] Step S410: If the current cumulative shutdown time of the air conditioner has not reached the set cumulative shutdown time of the air conditioner, determine whether the current running time of the air conditioner has reached the set running time of the air conditioner.

[0075] Step S420: If the current cumulative shutdown time of the air conditioner has not reached the set cumulative shutdown time, but it is determined that the current running time of the air conditioner has reached the set running time, then the current cumulative shutdown time of the air conditioner is reset to zero. The process then returns to re-determine whether the air conditioner is in a shutdown state. If it is re-determined that the air conditioner is in a shutdown state, then the time the air conditioner has been in a shutdown state is re-accumulated based on the current indoor ambient temperature and humidity, resulting in a cumulative shutdown time, which is recorded as the current cumulative shutdown time and stored. Specifically, if the air conditioner is turned on by remote control before the cumulative shutdown time meets the sterilization activation condition, the cumulative shutdown time can be cleared after the air conditioner's running time is reached. If the cumulative shutdown time meets the sterilization activation condition, the cumulative shutdown time will only be cleared after the sterilization process is completed.

[0076] Step S430, in the case that the current cumulative shutdown time of the air conditioner does not reach the set cumulative shutdown time of the air conditioner, if it is determined that the current running time of the air conditioner does not reach the set running time of the air conditioner, return to continue determining whether the air conditioner is in the shutdown state on the basis of the current cumulative shutdown time of the air conditioner, and if it is determined that the air conditioner is in the shutdown state, continue to accumulate the time during which the air conditioner is in the shutdown state according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner, to obtain a new cumulative shutdown time, denoted as a new current cumulative shutdown time of the air conditioner, and store the new current cumulative shutdown time of the air conditioner.

[0077] Specifically, as shown in Figure 8 The control method of the air conditioner's cleaning timing logic further includes: in step 22, determining whether the running time of the air conditioner reaches the set running time; if yes, clearing the accumulated time of the shutdown time of the air conditioner, and then re-accumulating the shutdown time of the air conditioner when the air conditioner is powered off after being powered on; otherwise, continuing to accumulate the shutdown time of the air conditioner.

[0078] Wherein, when the air conditioner is powered on before the fixed time t1 and the fixed time t2, the time t1 and the time t2 are cleared and re-timed when the air conditioner has been running for more than 5 minutes, at which time the microorganism aerosol carried by the residual air in the pipeline in the air conditioner has been completely blown out, and the air exchange in the air conditioner has been completed; if the sterilization function has been started, the time t1 and the time t2 are cleared and re-timed.

[0079] In some embodiments, the indoor unit of the air conditioner further has a deflector and an indoor fan.

[0080] In the case that the indoor unit of the air conditioner further has a deflector and an indoor fan, the step S140 of determining that the sterilization function of the air conditioner needs to be started to perform the sterilization action to start the sterilization function of the air conditioner to perform the sterilization action when the air conditioner is powered on further includes: after the sterilization device is controlled to be started, the original blowing angle of the deflector is switched to a preset sterilization blowing angle of the deflector, and the original wind gear of the indoor fan is switched to a preset sterilization wind gear of the indoor fan. Wherein, the preset sterilization blowing angle is like the preset minimum blowing angle, and the preset sterilization wind gear is like the preset minimum wind gear.

[0081] Specifically, Figure 9 The flowchart of an embodiment of the control method of the sterilization function logic of the air conditioner. As shown in Figure 9 The control method of the sterilization function logic of the air conditioner includes:

[0082] Step 31, after the sterilization condition is met, when the user uses the air conditioner, the sterilization function is started when the air conditioner is turned on. After the sterilization device of the air conditioner is turned on, if there is a deflector in the air outlet of the air conditioner, the deflector of the air conditioner is turned to the non-blowing state (such as the air outlet angle of the deflector is the minimum air outlet angle that can blow air), and the air damper of the indoor fan of the air conditioner is turned to the preset air damper of the sterilization state (such as the minimum air damper), and the sterilization time is obtained, and then step 32 is executed.

[0083] Step 32, determine whether the sterilization time reaches the set sterilization time: if yes, control the sterilization device to close, and the air outlet angle of the deflector and the air damper of the indoor fan are restored to the state before the sterilization device is turned on, such as restored to the state set by the user.

[0084] Among them, the sterilization device can be an ultraviolet, silver ion generator or a heater, etc. As long as it is a device that can kill bacteria. Generally, the sterilization device can work as long as it is powered, so the on-off of the sterilization device can be controlled by controlling whether the sterilization device is powered.

[0085] Figure 10 The schematic diagram of the deflector sweeping wind in the sterilization state of the ceiling-mounted air conditioner and the cabinet air conditioner is shown in Figure 10 The air conditioner shown in Figure 10 The air conditioner shown in Figure 11 The schematic diagram of the deflector sweeping wind in the sterilization state of the central air conditioner is shown in Figure 11 The air conditioner shown in Figure 11 The air conditioner shown in

[0086] Referring to the example shown in Figure 9 When the deflector of the air conditioner is turned to the non-blowing state, if the air conditioner is a ceiling-mounted or cabinet air conditioner, the air outlet angle of the first deflector 21 of the ceiling-mounted and cabinet air conditioner is inclined downward, as shown in Figure 10 The air outlet angle of the second deflector 22 of the central air conditioner is inclined to the side, as shown in Figure 11 Avoid blowing wind; at the same time, the fan speed is turned to the micro air damper of the sterilization state, so that the sterilization device can fully kill the microorganisms carried in the aerosol remaining in the air conditioner. After the sterilization time is up, the sterilization device is closed, and the deflector and the fan are restored to the set state.

[0087] In some embodiments, the step S140 of controlling the sterilization function of the air conditioner according to the current accumulated shutdown time of the air conditioner and the current running time after the air conditioner is turned on further comprises: a process of controlling the sterilization function of the air conditioner to be turned off, i.e., after determining that the sterilization function of the air conditioner needs to be turned on to perform the sterilization action, a process of controlling the sterilization function of the air conditioner to be turned off after the sterilization function of the air conditioner is turned on to perform the sterilization action.

[0088] The specific process of controlling the sterilization function of the air conditioner to be turned off in the step S140 will be further described below with reference to the flowchart of an embodiment of the process of controlling the sterilization function of the air conditioner to be turned off in the method of the air conditioner shown in Figure 5

[0089] The step S510 is to determine the running time of the sterilization function of the air conditioner, denoted as the sterilization time of the air conditioner, and determine the set sterilization time of the air conditioner according to the model of the air conditioner. The set sterilization time of the air conditioner is different when the model of the air conditioner is different.

[0090] The step S520 is to determine whether the sterilization time of the air conditioner reaches the set sterilization time of the air conditioner.

[0091] The step S530 is to control the sterilization function of the air conditioner to be turned off if the sterilization time of the air conditioner reaches the set sterilization time of the air conditioner. The control of the sterilization function of the air conditioner to be turned off comprises: controlling the sterilization device of the air conditioner to be turned off, and in the case that the indoor unit of the air conditioner has a deflector and an indoor fan, controlling the deflection angle of the deflector to return to the original deflection angle of the deflector and controlling the wind damper of the indoor fan to return to the original wind damper of the indoor fan. The original deflection angle of the deflector is the deflection angle of the deflector before the sterilization function of the air conditioner is turned on. The original wind damper of the indoor fan is the wind damper of the indoor fan before the sterilization function of the air conditioner is turned on.

[0092] The step S540 is to maintain the sterilization function of the air conditioner to be turned on if the sterilization time of the air conditioner does not reach the set sterilization time of the air conditioner, and then return to continue determining whether the sterilization time of the air conditioner reaches the set sterilization time of the air conditioner.

[0093] ​The sterilization time after the sterilization device is turned on can be automatically adjusted by judging the air conditioner type. Specifically, by obtaining the air conditioner type, the sterilization time can be automatically adjusted according to the specific conditions of the unit. It is known that the pipeline structure in the air conditioner, the air inlet and air outlet of the indoor unit of the hanging machine and the cabinet machine pass through a relatively short path, while the air inlet and air outlet of the indoor unit of the central air conditioner pass through a relatively long path. Therefore, the sterilization time is different. For example, the sterilization time T of the hanging machine and the cabinet machine is set to 90 s, and the sterilization time T of the central air conditioner is set to 5 min.

[0094] In the scheme of the present application, the judgment of the sterilization condition is made by the standby time of the air conditioner and the environmental temperature and humidity; the treatment of the air supply air of the air conditioner is made by judging the cumulative time of microorganisms, and combining the type of the air conditioner, the angle control of the air deflector and the fan control to sterilize the initial air supply of the air conditioner. Through the scheme of the present application, by combining the pipeline length in the air conditioner, the indoor environmental temperature and humidity and other conditions, while controlling the angle of the air deflector, the wind speed of the indoor fan and the like, the residual air in the pipeline in the air conditioner initially sent out at the start of the air conditioner is sterilized, which can effectively remove the microorganisms carried by the microbial aerosol carried by the residual air in the pipeline in the air conditioner, reduce the risk that the microorganisms breeding in the pipeline in the air conditioner are directly inhaled by the human body after entering the indoor air, and ensure the health of the human body.

[0095] The technical scheme of the present embodiment is adopted. In the case that the air conditioner is turned off after being powered on, the cumulative time of the air conditioner from being turned off to being turned on next time is counted under different temperature and humidity environments according to the indoor environmental temperature and the indoor environmental humidity of the environment where the air conditioner is located, and the cumulative turn-off time of the air conditioner is obtained. After the air conditioner is turned on, it is determined whether the cumulative turn-off time of the air conditioner reaches the set cumulative turn-off time of the air conditioner. If yes, the sterilization function of the air conditioner is turned on and the cumulative turn-off time of the air conditioner is cleaned. Otherwise, the cumulative turn-off time of the air conditioner is cleaned in the case that the running time of the air conditioner has exceeded the set running time, and the air conditioner is controlled to continue running and the cumulative turn-off time of the air conditioner is continued to be counted after the air conditioner is turned off in the case that the running time of the air conditioner has not exceeded the set running time. Wherein, the sterilization function is turned on, specifically, the sterilization device is turned on, the air deflector is controlled to have a preset sterilization air outlet angle, and the indoor fan is controlled to have a preset sterilization wind range. Therefore, whether sterilization is performed is determined according to the standby time of the air conditioner and the indoor environmental temperature and humidity, the air outlet angle of the air deflector and the wind range of the indoor fan are controlled during the sterilization process, and the sterilization time is controlled in combination with the type of the air conditioner, so that the residual air in the pipeline in the air conditioner initially sent out at the start of the air conditioner is sterilized, the microbial aerosol carried by the residual air in the pipeline in the air conditioner is effectively removed, and the health of the human body is beneficial.

[0096] According to the embodiments of the present application, a control device of an air conditioner corresponding to the control method of the air conditioner is also provided. Referring to Figure 6The structural schematic diagram of an embodiment of the device of the application is shown. The indoor unit of the air conditioner has an air outlet and a sterilization device; the sterilization device is arranged on the inner side of the air outlet, wherein the inner side of the air outlet is the inside of the air outlet along the air outlet direction of the air duct where the air outlet is located, and the outside of the air outlet is the outside of the air outlet. The control device of the air conditioner comprises an acquisition unit 102 and a control unit 104.

[0097] The acquisition unit 102 is configured to acquire the indoor environment temperature of the environment where the air conditioner is located after each power-on of the air conditioner, denoted as the current indoor environment temperature of the air conditioner; and acquire the indoor environment humidity of the environment where the air conditioner is located, denoted as the current indoor environment humidity of the air conditioner. For specific functions and processing of the acquisition unit 102, see step S110.

[0098] The control unit 104 is configured to determine whether the air conditioner is in a shutdown state after each power-on of the air conditioner; wherein the shutdown state includes a standby state and also includes a power-on and power-off state. For specific functions and processing of the control unit 104, see step S120.

[0099] The control unit 104 is further configured to, if it is determined that the air conditioner is in a shutdown state, accumulate the time when the air conditioner is in a shutdown state according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner, to obtain an accumulated shutdown time, denoted as the current accumulated shutdown time of the air conditioner, and store the current accumulated shutdown time of the air conditioner; for specific functions and processing of the control unit 104, see also step S130.

[0100] In some embodiments, the control unit 104 accumulates the time when the air conditioner is in a shutdown state according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner, to obtain an accumulated shutdown time, denoted as the current accumulated shutdown time of the air conditioner, including:

[0101] The control unit 104 is specifically further configured to determine whether the current indoor environment temperature of the air conditioner is greater than a set temperature, and determine whether the current indoor environment humidity of the air conditioner is greater than a set humidity. The set temperature is, for example, 20℃, and the set humidity is, for example, 70%. For specific functions and processing of the control unit 104, see also step S210.

[0102] The control unit 104 is further configured to, if it is determined that the current indoor environment temperature of the air conditioner is greater than the set temperature and that the current indoor environment humidity of the air conditioner is greater than the set humidity, accumulate the time during which the air conditioner is in the shutdown state to obtain a first accumulated shutdown time of the air conditioner; and record the first accumulated shutdown time of the air conditioner as the current accumulated shutdown time of the air conditioner. The first accumulated shutdown time is, for example, time t1. For details of the functions and processes of the control unit 104, see step S220.

[0103] The control unit 104 is further configured to, if it is determined that the current indoor environment temperature of the air conditioner is less than or equal to the set temperature and / or that the current indoor environment humidity of the air conditioner is less than or equal to the set humidity, accumulate the time during which the air conditioner is in the shutdown state to obtain a second accumulated shutdown time of the air conditioner; and record the second accumulated shutdown time of the air conditioner as the current accumulated shutdown time of the air conditioner. The second accumulated shutdown time is, for example, time t2. For details of the functions and processes of the control unit 104, see step S230.

[0104] Specifically, Figure 7 A flowchart of an embodiment of a control device for the timing logic of an air conditioner. As shown in Figure 7 The control device for the timing logic of an air conditioner comprises:

[0105] Step 11: After each power-on of the air conditioner, step 12 is performed.

[0106] Step 12: After each power-on of the air conditioner, the shutdown time of the air conditioner is started to be recorded. Specifically, it is determined whether the air conditioner is in the shutdown state. If yes, step 13 is performed to start recording the shutdown time of the air conditioner. If not, the shutdown time of the air conditioner is not recorded, and the shutdown time of the air conditioner is accumulated to be recorded after the next power-on of the air conditioner. Specifically, it is continuously determined whether the air conditioner is in the shutdown state, and the process is repeated.

[0107] Step 13: In the case where the air conditioner is in the shutdown state, it is determined whether the indoor environment temperature is greater than 20℃ and the indoor environment humidity is greater than 70%. If yes, step 14 is performed. If not, step 15 is performed.

[0108] Step 14: When the indoor environment temperature is greater than 20℃ and the indoor environment humidity is greater than 70%, the accumulated time of the shutdown time of the air conditioner is recorded as time t1. Then, step 16 is performed.

[0109] Step 15: When the indoor environment temperature is not greater than 20℃ or the indoor environment humidity is not greater than 70%, i.e., when the indoor environment temperature is less than 20℃ or the indoor environment humidity is less than 70%, the accumulated time of the shutdown time of the air conditioner is recorded as time t2. Then, step 16 is performed.

[0110] Step 16, record time t1 and time t2 in the storage unit, and continue to accumulate in the case of power on and off each time to update time t1 and time t2.

[0111] Wherein, only when the air conditioner is turned off, aerosol will be generated in the air conditioner, if it has been turned on, air exchange has been carried out inside and outside the air conditioner. Time t1 and time t2 are the shutdown time of the air conditioner, specifically, the shutdown time of the air conditioner after power on is accumulated, and the time from shutdown to the next start is accumulated. For example: the air conditioner is turned off after being turned on, the air conditioner is powered off after a period of time, the power is turned on after being powered off, and the air conditioner is still turned off after being powered on. The shutdown time of the air conditioner is recorded. As long as the air conditioner is turned off, the shutdown time of the air conditioner is always accumulated.

[0112] The control unit 104 is also configured to, if the air conditioner is turned on when the air conditioner is in the shutdown state, control the opening and closing of the sterilization function of the air conditioner according to the current accumulated shutdown time of the air conditioner and the current running time after the air conditioner is turned on, so that the pipeline inside the air conditioner is sterilized by the sterilization function of the air conditioner when the sterilization function of the air conditioner is turned on. Reduce the microbial content in the microbial aerosol carried by the residual air in the pipeline, reduce the microorganisms carried by the microbial aerosol, prevent the user from smelling odor after the air conditioner is turned on and affect the user experience, and also reduce the microbial aerosol carried by the residual air in the pipeline in the air conditioner into the room and affect human health. Wherein, it is determined that the sterilization function of the air conditioner needs to be turned on to perform sterilization action, so that the sterilization function of the air conditioner is turned on to perform sterilization action when the air conditioner is turned on, and the sterilization device is controlled to be turned on to sterilize when the air outlet of the air conditioner is turned on. The specific functions and processes of the control unit 104 are also referred to step S140.

[0113] The scheme of the application, by combining the length of the pipeline inside the air conditioner, the indoor environment temperature and humidity and other states, simultaneously controlling the angle of the air deflector, the wind speed of the indoor fan and other states, sterilizing the residual air in the pipeline inside the air conditioner when the air conditioner is turned on, and making the sterilization operation necessary and effective, thereby improving the user experience and ensuring human health; thereby, the microorganisms carried by the microbial aerosol carried by the residual air in the pipeline inside the air conditioner can be greatly reduced, the user can prevent smelling odor when the air conditioner is just turned on, the user experience can be improved, and the human health can be ensured.

[0114] In some embodiments, the control unit 104 controls the opening and closing of the sterilization function of the air conditioner according to the current accumulated shutdown time of the air conditioner and the current running time after the air conditioner is turned on, including:

[0115] The control unit 104 is specifically further configured to determine whether the current cumulative shutdown time of the air conditioner reaches the set cumulative shutdown time of the air conditioner. The specific functions and processes of the control unit 104 are also described in step S310.

[0116] In some embodiments, the current cumulative shutdown time of the air conditioner is the first cumulative shutdown time of the air conditioner or the second cumulative shutdown time of the air conditioner; the set cumulative shutdown time of the air conditioner is the first set cumulative shutdown time of the air conditioner or the second set cumulative shutdown time of the air conditioner; wherein, when the current cumulative shutdown time of the air conditioner is the first cumulative shutdown time of the air conditioner, the set cumulative shutdown time of the air conditioner is the first set cumulative shutdown time of the air conditioner; when the current cumulative shutdown time of the air conditioner is the second cumulative shutdown time of the air conditioner, the set cumulative shutdown time of the air conditioner is the second set cumulative shutdown time of the air conditioner; wherein, when the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner are different values, the set cumulative shutdown time corresponding to the current cumulative shutdown time of the air conditioner (i.e. the set cumulative shutdown time of the air conditioner) is also different values.

[0117] The control unit 104 determines whether the current cumulative shutdown time of the air conditioner reaches the set cumulative shutdown time of the air conditioner, including any of the following determination cases:

[0118] The first determination case: the control unit 104 is specifically further configured to determine whether the current cumulative shutdown time of the air conditioner reaches the first set cumulative shutdown time of the air conditioner, if the current cumulative shutdown time of the air conditioner is the first cumulative shutdown time of the air conditioner. The first set cumulative shutdown time of the air conditioner is, for example, 8 hours.

[0119] The second determination case: the control unit 104 is specifically further configured to determine whether the current cumulative shutdown time of the air conditioner reaches the second set cumulative shutdown time of the air conditioner, if the current cumulative shutdown time of the air conditioner is the second cumulative shutdown time of the air conditioner. The second set cumulative shutdown time of the air conditioner is, for example, 72 hours.

[0120] Wherein, the sterilization device of the air conditioner is arranged at the air outlet of the air conditioner, and the sterilization function is started when the air conditioner is started when the time t1 reaches 8 hours; the sterilization function is started when the air conditioner is started when the time t2 reaches 72 hours.

The specific functions and processes of the control unit 104 are also referred to step S410.

[0128] The control unit 104 is specifically further configured to, in the case that the current accumulated shutdown time of the air conditioner does not reach the set accumulated shutdown time of the air conditioner, if it is determined that the current running time of the air conditioner has reached the set running time of the air conditioner, the current accumulated shutdown time of the air conditioner is cleared, and then returned to re-determine whether the air conditioner is in the shutdown state, and then, if it is re-determined that the air conditioner is in the shutdown state, the time of the air conditioner in the shutdown state is re-accumulated according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner, to obtain the accumulated shutdown time, recorded as the current accumulated shutdown time of the air conditioner, and the current accumulated shutdown time of the air conditioner is stored. The specific functions and processes of the control unit 104 are also referred to step S420.

[0129] The control unit 104 is further configured to, in a case where the current accumulated shutdown time of the air conditioner does not reach the set accumulated shutdown time of the air conditioner, return to continue determining whether the air conditioner is in a shutdown state based on the current accumulated shutdown time of the air conditioner, and if it is determined that the air conditioner is in a shutdown state, continue accumulating the time for which the air conditioner is in a shutdown state according to the current indoor environment temperature of the air conditioner and the current indoor environment humidity of the air conditioner, to obtain a new accumulated shutdown time, denoted as a new current accumulated shutdown time of the air conditioner, and store the new current accumulated shutdown time of the air conditioner.

[0131] Wherein, when the air conditioner is powered on before the fixed time t1 and t2 is reached, the air conditioner is powered on, and when the air conditioner has been running for more than 5 minutes, the microorganism aerosol carried by the residual air in the pipeline in the air conditioner has been completely blown out, and the air exchange in the air conditioner has been completed, so the time t1 and t2 are cleared and re-timed; if the sterilization function has been started, the time t1 and t2 are cleared and re-timed.

[0132] In some embodiments, the indoor unit of the air conditioner further has a deflector and an indoor fan.

[0135] Step 31, after the sterilization condition is met, when the user uses the air conditioner, the sterilization function is started when the air conditioner is turned on. After the sterilization device of the air conditioner is turned on, if there is a deflector in the air outlet of the air conditioner, the deflector of the air conditioner is turned to the non-blowing state (such as the air outlet angle of the deflector is the minimum air outlet angle that can blow air), and the air damper of the indoor fan of the air conditioner is turned to the preset air damper of the sterilization state (such as the minimum air damper), and the sterilization time is obtained, and then step 32 is executed.

[0136] Step 32, determine whether the sterilization time reaches the set sterilization time: if yes, control the sterilization device to close, and the air outlet angle of the deflector and the air damper of the indoor fan are restored to the state before the sterilization device is turned on, such as restored to the state set by the user.

[0137] Among them, the sterilization device can be an ultraviolet, silver ion generator or a heater, as long as it can kill bacteria. Generally, the sterilization device can work as long as it is powered, so the on-off of the sterilization device can be controlled by controlling whether the sterilization device is powered.

[0138] Figure 10 The schematic diagram of the deflector sweeping wind in the sterilization state of the ceiling-mounted air conditioner and the cabinet air conditioner is shown in Figure 10 The air conditioner shown in Figure 10 The air conditioner shown in Figure 11 The schematic diagram of the deflector sweeping wind in the sterilization state of the central air conditioner is shown in Figure 11 The air conditioner shown in Figure 11 The air conditioner shown in

[0139] Referring to the example shown in Figure 9 When the deflector of the air conditioner is turned to the non-blowing state, if the air conditioner is a ceiling-mounted or cabinet air conditioner, the air outlet angle of the first deflector 21 of the ceiling-mounted and cabinet air conditioner is inclined downward, as shown in Figure 10 The air outlet angle of the second deflector 22 of the central air conditioner is inclined to the side, as shown in Figure 11 Avoid blowing wind; at the same time, the fan speed is turned to the micro air damper of the sterilization state, so that the sterilization device can fully kill the microorganisms carried in the aerosol remaining in the air conditioner. After the sterilization time is up, the sterilization device is closed, and the deflector and the fan are restored to the set state.

[0140] In some embodiments, the control unit 104 controls the opening and closing of the sterilization function of the air conditioner according to the current cumulative shutdown time of the air conditioner and the current running time after the air conditioner is turned on, and further comprises a process of controlling the sterilization function of the air conditioner to be closed, that is, after determining that the sterilization function of the air conditioner needs to be turned on to perform sterilization action, and after the sterilization function of the air conditioner is turned on to perform sterilization action when the air conditioner is turned on, the process of controlling the sterilization function of the air conditioner to be closed is further included, and the specific process is as follows:

[0141] The control unit 104 is specifically configured to determine the running time of the sterilization function of the air conditioner, denoted as the sterilization time of the air conditioner, and determine the set sterilization time of the air conditioner according to the model of the air conditioner.

[0142] The control unit 104 is specifically configured to determine whether the sterilization time of the air conditioner reaches the set sterilization time of the air conditioner. For specific functions and processes of the control unit 104, see step S520.

[0143] The control unit 104 is specifically configured to control the sterilization function of the air conditioner to be closed if the sterilization time of the air conditioner reaches the set sterilization time of the air conditioner. Controlling the sterilization function of the air conditioner to be closed includes controlling the sterilization device of the air conditioner to be closed, and in the case that the indoor unit of the air conditioner has a guide vane and an indoor fan, controlling the air outlet angle of the guide vane to return to the original air outlet angle of the guide vane, and controlling the air deflector of the indoor fan to return to the original air deflector of the indoor fan. The original air outlet angle of the guide vane is the air outlet angle of the guide vane before the sterilization function of the air conditioner is turned on. The original air deflector of the indoor fan is the air deflector of the indoor fan before the sterilization function of the air conditioner is turned on. For specific functions and processes of the control unit 104, see step S530.

For specific functions and processes of the control unit 104, see step S540.

[0145] The sterilization time after the sterilization device is turned on can be automatically adjusted by judging the air conditioner type. Specifically, by obtaining the air conditioner type, the sterilization time can be automatically adjusted according to the specific conditions of the unit. The known pipeline structure in the air conditioner, the short distance between the indoor air suction and the air supply in the hanging machine and the cabinet machine, and the long distance between the indoor air suction and the air supply in the central air conditioner, so the sterilization time is different. For example, the sterilization time T of the hanging machine and the cabinet machine is set to 90s, and the sterilization time T of the central air conditioner is set to 5min.

[0146] In the scheme of the present application, the judgment of the sterilization condition is made by the standby time of the air conditioner and the environmental temperature and humidity; the treatment of the air supply air of the air conditioner is made by judging the cumulative time of microorganisms, and combining the air conditioner type, the air deflector and the fan control to sterilize the initial air supply of the air conditioner after starting.
