The implementations described in the following exemplary examples do not represent all implementations consistent with the application. Rather, they are merely examples of apparatus and methods consistent with aspects of the application as detailed in the accompanying claims.
Fig. 1 is a flowchart illustrating a control method of an air conditioner according to an exemplary embodiment, and as shown in fig. 1, the method is applicable to an air conditioner, and includes:
step S11, responding to the air conditioner entering a heating mode, controlling the operation of a fan in the air conditioner at a preset maximum fan rotating speed, and starting each electric heater in the air conditioner;
step S12, acquiring the current air outlet temperature, the current external temperature and the set temperature of the air conditioner;
step S13, controlling and adjusting the current fan rotating speed of the fan in the air conditioner and the running state of each electric heater in the air conditioner based on the current air outlet temperature, the current external temperature and the set temperature; wherein the running state is on or off.
In this embodiment, the execution body may be an air conditioner control device provided in an air conditioner.
The starting of the heating mode can be started manually by a user, and the user can set conditions such as a fan gear, the current environment temperature, the current set machine temperature and the like to enter the heating mode. When the heating mode is started by default, controlling the fan in the air conditioner to run at a preset maximum fan rotating speed, and starting all electric heaters in the air conditioner. The preset maximum fan rotating speed is a preset fan rotating speed corresponding to the maximum power of the electric heater.
And after entering the heating mode and when the air conditioner is stable in operation, the execution main body can monitor the current air outlet temperature, the current external temperature and the set temperature of the air conditioner in real time. If the current fan rotation speed reaches the preset maximum fan rotation speed or other set rotation speeds, the fan rotation speed tends to be stable, and the current air outlet temperature also tends to be stable, the air conditioner is determined to be stable in operation.
Then, the executing body can adjust the current fan rotating speed and adjust the running state of each electric heater in the air conditioner based on the current air outlet temperature, the current external temperature and the set temperature obtained by real-time monitoring, namely, the electric heaters are controlled to be turned on or off. The maximum fan rotating speed and the minimum fan rotating speed are preset for the fan of the air conditioner, and numerical adjustment is carried out on all adjustment of the current fan rotating speed based on the interval from the minimum fan rotating speed to the maximum fan rotating speed, so that the interval cannot be exceeded. The operation state of each electric heater in the air conditioner can be adjusted respectively, and the number of the electric heaters in the air conditioner is multiple. Preferably, when the operation state of each electric heater in the air conditioner is adjusted, different adjustment levels can be preset, and the different adjustment levels correspondingly adjust the closing or opening of different numbers of electric heaters, so that the gradual adjustment of the electric heaters is realized. For example, if the air conditioner includes 3 electric heaters (first electric heater, second electric heater, third electric heater), the adjustment levels of the priority levels from high to low may be preset in order as follows: the first electric heater is turned off, the second electric heater is turned on, and the third electric heater is turned on; the first electric heater is turned off, the second electric heater is turned off, and the third electric heater is turned on; the first electric heater is turned off, the second electric heater is turned off, and the third electric heater is turned off. The operation state of the electric heater is adjusted by the step-by-step adjustment level, so that the electric heater can be turned off step by step, and compared with the mode of turning off all the electric heaters at one time, the step-by-step adjustment mode is more flexible, the on-off adjustment frequency of the electric heater can be reduced, and the electric heater is prevented from being started frequently.
Based on the above, aiming at the prior air conditioner control method, the electric heater is always in the running state of the maximum power when in work, when in the running state of the maximum power, the heating amount of the electric heater body is high, the temperature of wind blown out by the air conditioner is also very high, the temperature of the air outlet of the air conditioner is overheated, the user experience feel bad, the power consumption of the air conditioner is large, the energy conservation and the environmental protection are not realized, and the electric heater is frequently started and stopped, so that the service life of the electric heater is damaged. In this way, the application adjusts the air outlet temperature and the operation power of the electric heater by adjusting the rotating speed of the fan based on the proportional relation between the operation power of the electric heater and the air inlet speed of the electric heater, ensures the stability of the air outlet temperature, improves the user experience comfort, avoids frequent starting of the electric heater, and can gradually reduce the use of electric heating starting under the permission of the temperature state, thereby reducing the power consumption and protecting the service life of the electric heater.
Specifically, the air outlet temperature and the running power of the electric heater are adjusted by adjusting the rotating speed of the fan in a heating mode, so that the air outlet temperature is consistent with the set temperature, and the phenomenon of poor user experience caused by large temperature difference between the air outlet temperature and the set temperature is reduced; in the temperature regulation process, if the air outlet temperature is higher than the set temperature, the use of electric heating can be reduced step by step, the air outlet temperature is reduced to reach the set temperature, the use of an electric heater is reduced, and meanwhile, the power consumption is reduced, and the service life of the electric heating is protected.
As an alternative embodiment, controlling and adjusting the current fan rotation speed of the fan in the air conditioner and the operation state of each electric heater in the air conditioner based on the current outlet air temperature, the current external temperature and the set temperature includes:
and if the current external temperature is greater than or equal to the set temperature and the difference between the current air outlet temperature and the set temperature is less than or equal to a preset value, maintaining the current fan rotating speed of the fan in the air conditioner and the running state of each electric heater in the air conditioner.
In this embodiment, the preset value may be a smaller value that is preset, for example, the preset value may be set to 2, the current outlet air temperature is denoted as tsout, the current external temperature is denoted as tsout, and the set temperature is denoted as tsout. If T is greater than or equal to T and T is greater than or equal to 2, maintaining the current fan rotating speed of the fan in the air conditioner and the running state of each electric heater in the air conditioner. Under the condition of first regulation that all electric heaters are started, the current fan rotating speed of a fan in the air conditioner is maintained to be a preset maximum fan rotating speed, and the running state of each electric heater is maintained to be started.
As an alternative embodiment, controlling and adjusting the current fan rotation speed of the fan in the air conditioner and the operation state of each electric heater in the air conditioner based on the current outlet air temperature, the current external temperature and the set temperature includes:
and if the current external temperature is greater than or equal to the set temperature and the difference between the current air outlet temperature and the set temperature is greater than a preset value, reducing the current fan rotating speed of the fan in the air conditioner by a preset rotating speed value.
In the embodiment, if T is greater than or equal to T and T is greater than 2, the rotation speed of the fan can be reduced. The preset rotation speed value is a preset constant value for each adjustment of the rotation speed of the fan, for example, the preset rotation speed value may be set to 10. At this time, if T is greater than or equal to T and T is greater than 2, the current fan speed is adjusted (reduced by 10), i.e., R=R-10. Wherein R is the current fan speed. It can be appreciated that the current fan speed is adjusted to be within a reasonable interval between the maximum fan speed and the minimum fan speed, i.e., R > Rmin after adjustment. Wherein Rmin is a preset minimum fan speed.

Gtoreq.Tset and Tout-Tset > 2. In contrast, if the electric heater in the on state exists in the air conditioner, the target electric heater is selected to be turned off from the electric heaters in the on state. Preferably, for each electric heater, a closing priority of the electric heater is preset. When the target electric heater is selected from the electric heaters in the on state to be turned off, the electric heater with the highest turn-off priority can be selected as the target electric heater to be turned off according to the order of the turn-off priority from high to low. After the target electric heater is turned off, in order to prevent the exhaust air temperature from suddenly decreasing, the temperature difference is large, and the fan rotation speed is adjusted to the fan rotation speed with the maximum power of the electric heater operation, namely, r=rmax. Wherein Rmax is the preset maximum fan speed. And after the operation is stable, repeatedly executing the control strategy based on the current air outlet temperature, the current external temperature and the set temperature.
In addition, if R-10 is less than or equal to Rmin and no electric heater in an on state exists in the air conditioner, the electric heaters are all turned off, the turn-off control strategy of the electric heaters is not executed at the moment, the current fan rotating speed is controlled to operate according to R=Rmin, and the electric heaters are all operated in the off state at the moment. At this time, when the set temperature changes, the heating mode is re-entered, and all the electric heaters are started. The set temperature is here set manually by the user.
As an optional implementation manner, after reducing the current fan rotation speed of the fan in the air conditioner by the preset rotation speed value, the method further includes:
and if the current external temperature is smaller than the set temperature, increasing the current fan rotating speed of the fan in the air conditioner by the preset rotating speed value.

And if T is smaller than T, controlling the current fan rotating speed to be changed into R=R+10, and keeping the running state of the electric heater unchanged. If T is not less than T and T is not less than 2, the current fan rotating speed is kept unchanged, and the running state of the electric heater is kept unchanged. If Tout is greater than or equal to Tset and Tout-Tset > 2 at this time, R=R-10 as described above is repeatedly executed.

If the closed electric heater exists in the air conditioner, the corresponding target control mode can be determined to be at least one electric heater which controls the current fan rotating speed to be the preset minimum fan rotating speed and is closed in the on-state. Preferably, when at least one electric heater in the closed state is turned on, the electric heater in the closed state with the lowest closing priority may be selected to be turned on according to the sequence from low to high of the closing priorities corresponding to the electric heaters.
