a detection step, which is used for detecting an air deflector angle zone bit Alt after the air conditioner is started;
a judging step, namely judging that the angle flag bit Alt of the air deflector is 0,1 or 2;
a control step, which is used for controlling the air deflector to sweep wind up and down and enter a uniform refrigeration mode when the angle flag bit Alt of the air deflector is equal to 0; when the angle flag bit Alt of the air deflector is 1, controlling the angle of the air deflector to be fixed to a set stop-motion angle for operation and entering a stop-motion air-guiding refrigeration mode; when the angle flag bit Alt of the air deflector is 2, the angle of the air deflector is controlled to be fixed to be operated at a direct blow preventing angle, and the air deflector enters a direct blow preventing mode.
According to the air conditioner, after the air conditioner is started, the angle flag bit Alt of the air deflector is detected, whether the angle flag bit Alt is one of 0,1 and 2 is judged, and when the Alt is equal to 0, the air deflector is controlled to perform up-and-down air sweeping motion and enter a uniform refrigeration mode, so that the problems that the temperature of each area of a room is not uniform during air conditioner refrigeration, the temperature of a place where cold air can be blown is fast reduced, the temperature is low, and the refrigeration effect is poor due to the fact that air outlet cannot be distributed in a part of areas are solved, the air conditioner can achieve uniform air sweeping of the interior of the room, and the uniformity distribution of indoor temperature; when Alt is 1, the angle of the air deflector is controlled to be fixed to a set stop-motion angle for operation, and the air deflector enters a stop-motion air-guiding refrigeration mode, so that stop-motion operation can be realized, cold air is prevented from being blown directly to a person, and the requirement of positioning and cold air supply of a human body can be met; when Alt is 2, the angle of the air deflector is controlled to be fixed to be operated at a direct blowing prevention angle, and the direct blowing prevention mode is entered, so that the problem that a user is easy to catch a cold once the user forgets to learn, play games and sleep after the user operates for a period of time at present can be solved, the direct blowing prevention mode is effectively and automatically entered, manual setting is not needed, and the user is prevented from catching a cold due to cold wind blowing; therefore, the operation stage of the current air conditioner is judged through logic control, the motion mode of the air deflector is flexibly adjusted, the air deflector can be operated in a full-house three-dimensional surrounding air supply mode, uniform refrigeration of a room is realized, and the air deflector can be operated in a fixed grid manner, cold air is prevented from blowing people during refrigeration, people feel cool like transparent, meanwhile, the air deflector automatically enters a direct blowing prevention mode according to the requirements of users on cold quantity and comfort at different moments and in different states, manual setting is not needed, and the cold air is prevented from cooling the users; the problem that people are blown by cooling cold wind is solved, and the problem that the temperature distribution in a cooling room is uneven is also solved.
In some embodiments, the determining step is further configured to continuously determine which of 0,1 and 2 the angle flag Alt of the air deflector is after the air conditioner enters the uniform cooling mode;
the control step is also used for controlling the air conditioner to exit the uniform refrigeration mode, controlling the angle of the air deflector to be fixed to a set stop angle to operate and entering the stop air guide refrigeration mode when the angle flag bit Alt of the air deflector is judged to be 1 after the air conditioner enters the uniform refrigeration mode; and the air conditioner is also used for controlling the air conditioner to exit from the uniform refrigeration mode and controlling the angle of the air deflector to be fixed to operate at a direct blowing prevention angle and enter into the direct blowing prevention mode when the angle flag bit Alt of the air deflector is judged to be 2 after the air conditioner enters into the uniform refrigeration mode.
The air conditioner is a further preferable control method after entering the uniform refrigeration mode, namely after entering the uniform refrigeration mode, the flag bit Alt of the air deflector still becomes 1 or 2, and the possibility of changing to 1 is that the air conditioner starting Alt defaults to 0; after the air deflector is started, the air deflector is defaulted to be in wind sweeping operation, and after the controller receives an up-down wind sweeping command for the first time, the air deflector can be in fixed operation according to the angle of the air deflector at the moment of receiving the command; after receiving the 'up-down wind sweeping' instruction 2, 3, 4, 5 and 6 times, the air deflector respectively operates according to the fixed angles of the fixed frame 1, the fixed frame 2, the fixed frame 3, the fixed frame 4 and the fixed frame 5, wherein Alt is 1; the key pressing times of the 'up-down wind sweeping' key are different, and the final stop-motion angle of the air deflector is also different, so that the requirement of a user on the operation of the stop-motion air deflector angle is met; when the accumulated running time, the environmental temperature difference and the running frequency of the compressor are met, the angle zone bit of the air deflector can be changed into 2, and then the direct blowing prevention mode can be entered, or when a remote control command 'one-key direct blowing prevention' of a user is received, the angle zone bit of the air deflector can also be changed into 2, and the direct blowing prevention mode can be entered. The former is because the user is to the requirement of air-out angle travelling comfort this moment, and the latter is under certain circumstances, and the user probably has the requirement of preventing blowing directly before satisfying the judgement condition, and the user directly gets into through the remote control button and prevents blowing directly mode this moment
In some embodiments, the detecting step is further configured to detect a startup time T and an indoor environment temperature T of the air conditionerRing (C)And a current air conditioner operating frequency F;
the judging step is also used for judging the starting time t and tPreset ofThe relation between them, and determining TRing (C)-TIs provided withWhether or not less than TError of the measurementAnd determining whether F is less than FPreset of；

The optimal control method is that when the accumulated running time, the environmental temperature difference and the running frequency of the compressor are met, the angle flag bit of the air deflector can be changed into 2, and then the direct blowing prevention mode can be entered, and when t is more than or equal to tPreset ofOr Δ T ≦ TError of the measurementOr F is less than or equal to FPreset ofWhen the temperature is higher, the operation time of the uniform refrigeration mode of the up-down wind sweeping is longer or the indoor environment temperature tends to be higherAt a predetermined temperature tPreset ofOr the running frequency F of the air conditioner is lower than a low-frequency numerical value (the representation reaches a preset value), which shows that the indoor refrigeration effect basically meets the requirement at the moment, so that the control enters the direct blowing prevention mode, the direct blowing prevention effect on indoor users is ensured, the comfort of the users is improved, and the situation that the comfort degree is poor due to direct blowing is avoided.
In some embodiments, t isPreset of＝30min；T Error of the measurement2 deg.c. When the uniform refrigeration mode is operated for a certain time, the difference value between the operation time of the open-top machine and the inlet air temperature and the set temperature and the operation frequency of the air conditioner are judged, and if T is more than or equal to 30min or delta T is less than or equal to 2 ℃ or F is less than or equal to FPreset ofAnd if the air guide plate is in the uniform refrigeration mode, the air guide plate is in the direct blowing prevention angle operation, the Alt is reset to be 2, and the direct blowing prevention mode is entered.
As shown in the figure, the air deflector is a large air deflector motion structure pushed out by a driving strip, the front end of the driving strip is provided with a motor, the motor is matched with the air deflector, and the air deflector is driven to rotate by 360-degree rotation of the motor. The air deflector is started, the air deflector is defaulted to be in wind sweeping operation, and the air deflector can be fixed (stopped randomly) after receiving the air deflector change instruction again; in addition, the air deflector has 6 preset stop angles (stop 1, stop 2, stop 3, stop 4, stop 5 and direct blow prevention). After the user got into the room in summer, can open the air conditioner and set up a key through the remote control and get into the refrigeration mode of enjoying comfortable, just begin the room in the temperature and set for the temperature difference great, most users hope that the room can rapid cooling this moment, and can not mind the cold wind and blow the people, program control air conditioner carries out the even refrigeration operation that the whole room three-dimensional surrounds the air supply this moment, and cold wind can all-round send the room everywhere, makes temperature can evenly descend fast in the room. After the air conditioner is operated for a period of time, the difference value between the temperature in the room and the set temperature is smaller and smaller, the requirement of a user on cold quantity is not strong at the moment, the cold air blown to the body is sensitive, the uniform refrigeration is automatically quitted through judgment of control conditions, the angle of the air deflector is fixed to be a direct-blowing prevention fixed-grid angle, and the cold air is blown upwards to avoid the user.
And (3) operation design:
when a user starts up, the remote controller is used for setting refrigerationTemperature TIs provided withAfter the one-key cooling mode is entered, the air guide plate defaults to wind sweeping operation, Alt is judged to be 0 (the air guide plate angle flag bit is a judgment condition when the controller enters different modes, the numerical value is 0,1 and 2 represent three air guide plate motion modes, namely wind sweeping operation, common stop motion angle (5 stop motion angles) and direct blow prevention stop motion angle (direct blow prevention angle), and meanwhile, the starting operation time T and the room internal environment temperature T are output and memorizedRing (C). Then, judging the Alt, and if the Alt is 0, entering a uniform refrigeration mode (when the air conditioner is started, a user has higher requirement on the refrigeration effect, the angle zone bit of the air deflector is defaulted to be 0 to ensure the uniform and efficient refrigeration effect of a room, and at the moment, a controller program judges that the air deflector enters the uniform refrigeration mode through the zone bit and controls a motor to drive the air deflector to sweep wind up and down); if Alt is 1, the air deflector operates at a fixed air deflector angle according to a received air deflector angle instruction (in some cases, a user needs to set a certain fixed air deflector angle to operate, in order to meet the requirement, when a remote control instruction of the user is received (the user presses an up-down wind sweeping key on a remote controller), a flag bit is changed into 1, at the moment, a program enters a grid-fixed operation mode by judging the numerical value of the flag bit, the air deflector angle is a grid, a specific angle is determined according to the number of times of pressing the up-down wind sweeping key by the user, and the explanation of Alt in the following table 1 is followed); if Alt is 2, the aviation baffle is fixed to prevent the direct-blowing angle operation (when the three conditions of the start-up accumulated operation duration, the ambient temperature difference change and the compressor operation frequency difference change satisfy one of them, the user diminishes the demand on the refrigeration effect, and the requirement on the comfort of the air-out angle to the people becomes high, and the aviation baffle angle flag bit becomes 2 at this moment, and the program judges to enter into the direct-blowing prevention mode at this moment, controls the aviation baffle to be fixed to prevent the direct-blowing angle operation, avoids the cold wind to blow to the people), and enters into the direct-blowing prevention mode. Continuously judging Alt in the uniform refrigeration operation process, if Alt is 1, exiting from the uniform refrigeration mode, and fixing the angle of the air deflector to operate according to the received angle instruction of the air deflector by the air deflector; if Alt is 2, the uniform refrigeration mode is exited, the air deflector is fixed to operate at the direct blow prevention angle, and the direct blow prevention mode is entered; and if Alt is equal to 0, continuing to operate in the uniform cooling mode. When the uniform refrigeration mode is operated to a certain degreeAfter the time, the difference value between the running time of the starting machine and the inlet air temperature and the set temperature and the running frequency of the air conditioner are judged, and if T is more than or equal to 30min or delta T is less than or equal to 2 ℃ or F is less than or equal to FPreset ofAnd exiting the uniform refrigeration mode, enabling the air guide plates to operate at the fixed anti-blow-through angle, resetting Alt to be 2, and entering the anti-blow-through mode (the air guide plates are at fixed angles, the former air guide plate is at the fixed anti-blow-through angle, and the latter air guide plate is at the same fixed angle, but different fixed angles can be changed through remote control of a user).
In some embodiments, the controlling step is further configured to control the angle flag Alt of the air deflector to default to 0 after the air conditioner is turned on, the default is to perform a wind sweeping operation, and the air conditioner enters a uniform cooling mode.
In some embodiments, the determining step is further configured to determine whether the controller receives an "up-down wind sweeping" instruction and count the number of times the "up-down wind sweeping" instruction is received;
and the control step is also used for controlling the angle flag bit Alt of the air deflector to be 1 when the up-down wind sweeping command is received and the number of times of receiving the up-down wind sweeping command is less than or equal to N times, controlling the angle of the air deflector to be fixed to a set stop-motion angle for operation, and entering a stop-motion air guiding and refrigerating mode, wherein N is a natural number.
In some embodiments, the stop motion angles of the air deflectors are different in the N times; and/or, said N ═ 6.
In some embodiments, the control step is further configured to, when the number of times of receiving the "wind sweeping up and down" command is greater than N times, control the angle flag bit Alt of the air deflector to be 0, and control the air deflector to wind up and down and enter the uniform cooling mode again.
