the valve driver 842 controls the number of open vent valves 703; when the power of the suction fan 602 is not changed, the amount of wind rotationally sucked by the suction fan 602 is also not changed, and when the number of the ventilation valves 703 is reduced, the static pressure energy of the wind in the outer cover 601 is converted into kinetic energy, so that the flow velocity of the wind is increased, the spraying distance is increased, the flowing speed of the air in the space can be increased, the heat exchange in the space is accelerated, the space cooling is accelerated, meanwhile, the area farther away from the air conditioner can quickly obtain cold wind with lower temperature, the cooling speed of the area farther away is further accelerated, and the cooling effect is improved;
the vertical cabinet type household air conditioner indoor unit and the control method thereof comprise the following steps:
when the air conditioner internal unit is just started, the air conditioner internal unit is in a default state, and the default state is as follows: the suction fan 602 of the upper air cooling mechanism 3 is opened, the exhaust fan 603 of the upper air cooling mechanism 3 is closed, the suction fan 602 of the lower air cooling mechanism 5 is closed, the exhaust fan 603 of the lower air cooling mechanism 5 is opened, and the ventilation valve 703 of the upper air cooling mechanism 3 and the ventilation valve 703 of the lower air cooling mechanism 5 are both opened;
the upper temperature sensor 9 and the lower temperature sensor 901 of each temperature sensor group measure real-time temperature at preset time intervals, and transmit the measured real-time temperature value to the main controller 8;
when the real-time temperature values of the upper temperature sensor 9 and the lower temperature sensor 901 of one temperature sensor group close to the indoor unit of the air conditioner all reach the preset indoor temperature value, and the temperature difference value between the upper temperature sensor 9 and the lower temperature sensor 901 of the group is smaller than the preset temperature difference threshold value of the group, and the temperature difference value outside the group of one temperature sensor group adjacent to the temperature sensor group is larger than the preset temperature difference threshold value outside the group, then the far wind state is triggered, and the far wind state is as follows: the number of vent valves 703 open is reduced; the number of the open ventilation valves 703 is reduced compared to the number in the default state, and in the default state, all the ventilation valves 703 should be opened to accelerate the cooling;
when the intra-group temperature difference value of each temperature sensor group is smaller than the preset intra-group temperature difference threshold value, and the inter-group temperature difference value of the adjacent temperature sensor group is smaller than the preset inter-group temperature difference threshold value, the constant state is triggered, and the constant state is as follows: the suction fan 602 of the upper air cooling mechanism 3 is closed, the exhaust fan 603 of the upper air cooling mechanism 3 is opened, the suction fan 602 of the lower air cooling mechanism 5 is opened, and the exhaust fan 603 of the lower air cooling mechanism 5 is closed; when the constant state is maintained, the whole space reaches the preset indoor temperature, and in order to maintain the temperature, the air conditioner needs to be continuously started; because rapid cooling is not needed at this time, the air conditioner is adjusted to be in a mode of upper air outlet and lower air inlet, the cold air blown out from the upper air cooling mechanism 3 of the air conditioner can spontaneously promote the air in the space to flow due to the downward falling of the cold air, so that the human body can be prevented from feeling too cold, and meanwhile, the preset temperature difference threshold value in each temperature sensor group is the range of the temperature difference value in the upper temperature sensor 9 and the lower temperature sensor 901 of each temperature sensor group;
the preset out-group temperature difference threshold value is the range of the out-group temperature difference value of the set phase group temperature measurement sensor group;
the preset indoor temperature value is the temperature value of the air conditioner set in the prior art;
in the application, a plurality of temperature sensor groups are used for cooling a plurality of areas divided by the plurality of temperature sensor groups from near to far according to the sequence from near to far of the air conditioner, and the calculation of the temperature difference value outside the group is a calculation value between the temperature sensor groups of two adjacent areas;
the intra-group temperature difference value is used for representing whether the temperature of the space of the current region is uniform or not, if the intra-group temperature difference value is smaller than a preset intra-group temperature difference threshold value, the upper temperature and the lower temperature of the region are uniform, and if the measured values of the upper temperature sensor 9 and the lower temperature sensor 901 in the region reach the preset indoor temperature, the cooling effect of the region is the best, and at the moment, the temperature value of a far region can be obtained, the intra-group temperature difference value calculation is carried out, and the cooling effect of the far region is cooled or increased;
therefore, the workload of the multiple temperature measuring sensor groups is reduced from less to more, and the calculated amount is reduced from less to more, so that the calculated amount can be reduced to a certain extent, and the control sensitivity of the air conditioner is improved;
according to the control method of the vertical cabinet type household air conditioner indoor unit, when the air conditioner indoor unit is in a default state, a far wind state and a constant state, the running power of the wind plate motor 704 is adjusted according to the temperature difference value inside the group and the temperature difference value outside the group, and when the temperature difference value inside the group or the temperature difference value outside the group is large, the running power of the wind plate motor 704 is increased; when the intra-group temperature difference value or the inter-group temperature difference value is small, the operation power of the air vane motor 704 is reduced.
In addition, the remote controller 10 connected to the air plate motor 704 of the middle air cooling mechanism 4 is not only used for receiving signals of an infrared remote controller, and setting the rotation speed and angle of the air plate motor 704 through manual remote control, and when a period of time elapses, that is, when the air conditioner enters a far air state, the remote controller 10 autonomously adjusts the rotation of the air plate motor 704, so that the air guide plate 701 rotates to a horizontal state, and in the far air state, the blockage of the air guide plate 701 to the air can be reduced, the distance of the air ejected from the middle air cooling mechanism 4 is increased, and the cooling speed and the cooling effect of a far area can be effectively promoted.
