Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
As shown in fig. 1, an air conditioner control method according to an embodiment of the present invention includes: in a refrigeration mode, acquiring a shutdown instruction; controlling the air deflector to close or blow air upwards; and controlling the compressor to run at a low frequency and controlling the air conditioner to execute a heating mode.
After the air conditioner finishes refrigeration shutdown, the humidity of the air in the air duct can reach more than 90%, and a lot of condensed water is condensed on the evaporator fins, so that the air conditioner control method provided by the embodiment of the invention obtains a shutdown instruction in a refrigeration mode, and further processes and improves the humid environment in the air duct of an indoor unit of the air conditioner.
Specifically, when the air conditioner operates in a cooling mode, an instant shutdown instruction or a timing shutdown instruction from a remote controller, a voice control or an intelligent mobile terminal is received.
When an instant shutdown instruction is received, other parts are immediately controlled to be closed, the low-frequency operation of the compressor is controlled, and the load increase caused by the overlarge pressure difference of the compressor is prevented. After the compressor operates stably for a period of time, the four-way valve is controlled to change direction, so that the air conditioner executes a heating mode. For example, when the compressor steady operation time is greater than or equal to 6s, the air conditioner is controlled to execute the heating mode.
When a timing shutdown instruction is received, after the air conditioner runs for a corresponding time, the compressor is controlled to run at a low frequency, and after the compressor runs for a period of time stably, the air conditioner is controlled to execute a heating mode.
Wherein, the operation of the external fan can be controlled to enhance the heating effect.
The method provided by the embodiment of the invention can control the air deflector to be closed and also can control the air deflector to blow upwards, thereby avoiding blowing hot air to a user and influencing the use experience.
When the air guide plate is controlled to blow air upwards, hot air is accumulated above the indoor environment, and the influence on the indoor environment temperature can be reduced.
When the air deflector is closed, the heat transfer efficiency in the air duct of the air conditioner indoor unit can be improved, so that the evaporator can fully improve the temperature, remove condensed water and reduce the humidity; after the heating mode is closed, the heat retention time in the air duct can be prolonged, and the condensed water is fully dried by using the waste heat.
According to the air conditioner control method provided by the embodiment of the invention, the shutdown instruction is obtained in the refrigeration mode, the low-frequency operation of the compressor is controlled, and the air conditioner executes the heating mode, so that the internal temperature of the air duct of the inner machine is raised, the temperature of the evaporator is raised, the effect of removing condensed water or preventing the generation of the condensed water is realized, the rusting or the mildew is prevented, and the safety performance of the air conditioner is improved; the air deflector is controlled to be closed or the air is blown upwards, so that the air flow is prevented from being blown to a user, and the use experience is prevented from being influenced.
The control of the low-frequency operation of the compressor specifically comprises the following steps: acquiring the running frequency of the compressor in a refrigeration mode; when the running frequency is greater than the preset frequency, controlling the compressor to run according to the preset frequency; and when the running frequency is less than or equal to the preset frequency, controlling the compressor to run according to the running frequency. The low-frequency operation of the compressor can play a role in saving energy on one hand and can prevent the shutdown caused by the increase of load on the other hand.
The preset frequency can be set manually or generated automatically according to the indoor environment temperature. For example, when a shutdown instruction of the air conditioner is acquired, the indoor ambient temperature is acquired; when the indoor environment temperature is less than or equal to 16 ℃, the preset frequency is automatically set to be 75 Hz; when the indoor environment temperature is higher than 16 ℃ and lower than or equal to 22 ℃, the preset frequency is automatically set to 63 Hz; when the indoor environment temperature is greater than 22 ℃ and less than or equal to 29 ℃, the preset frequency is automatically set to be 40 Hz. It should be noted that, the present invention does not limit the setting of the preset frequency, and those skilled in the art can set the preset frequency according to actual situations.
In order to ensure the working effect of the compressor, prevent the shutdown caused by overhigh internal temperature of the air conditioner and overlarge load of the compressor, and also prevent the influence on the heating effect caused by overlow internal temperature of the air conditioner, the temperature of an evaporator coil is also obtained after the air conditioner executes a heating mode; the operating frequency of the compressor is controlled and adjusted based on the evaporator coil temperature.
For example, when the temperature of the evaporator coil is more than 58 ℃ and less than or equal to 60 ℃, the compressor is controlled to rapidly reduce the frequency until the temperature of the evaporator coil reaches 58 ℃;
when the temperature of the evaporator coil is higher than 52 ℃ and lower than or equal to 58 ℃, controlling the compressor to slowly reduce the frequency until the temperature of the evaporator coil reaches 52 ℃;
when the temperature of the evaporator coil is more than 50 ℃ and less than or equal to 52 ℃, controlling the compressor to keep the current frequency and not to decrease any more;
when the temperature of the evaporator coil is more than 48 ℃ and less than or equal to 50 ℃, controlling the compressor to slowly increase the frequency until the temperature of the evaporator coil is more than 50 ℃;
when the evaporator coil temperature is less than or equal to 48 ℃, the compressor is controlled to rapidly increase the frequency until the evaporator coil temperature is greater than 48 ℃.
In the process, the compressor has the lowest operating frequency and the highest operating frequency, and when the compressor is lowered to the lowest operating frequency, the compressor does not continuously descend; when the compressor is raised to the maximum operating frequency, the compressor will not continue to rise. The lowest operating frequency may be set according to practical circumstances, and may be set to 20Hz, for example. The highest operating frequency is the preset frequency of the compressor.
It should be noted that the above-mentioned embodiments are only used for illustration and do not limit the present invention, and those skilled in the art can adjust the operation frequency of the compressor according to the conventional method known in the prior art based on the understanding of the present invention.
In order to accelerate the air flow circulation in the air duct of the indoor unit of the air conditioner and improve the heat transfer efficiency, the control method of the air conditioner also controls the inner fan to operate according to the preset rotating speed. The preset rotating speed is a preset rotating speed, and in order to avoid generating larger noise to influence the use experience, preferably, the preset rotating speed is a low rotating speed. For example, the preset rotation speed may be set to 400RPM, may be set to 800RPM, and may be set to any value of 400 to 800 RPM.
Further, as shown in fig. 2, the operation duration of the air conditioner in the heating mode is compared with a preset duration, and when the operation duration of the air conditioner in the heating mode is greater than or equal to the preset duration, the compressor and the inner fan are controlled to be turned off, and the air conditioner enters the standby mode; otherwise, controlling the compressor and the inner fan to continue to operate. The preset time is the running time of the preset air conditioner in the heating mode, the heating effect on the air duct inside the air conditioner is guaranteed during the preset time, and the influence of the overlong running time on the indoor environment temperature is avoided. For example, the preset time period may be set to 30s, may also be set to 180s, and may also be set to any value of 30 to 180 s.
The following describes the air conditioner control device provided by the present invention, and the air conditioner control device described below and the air conditioner control method described above may be referred to in correspondence with each other.

After the compressor operates stably for a period of time, the control unit controls the four-way valve to change direction, so that the air conditioner executes a heating mode. For example, when the compressor stable operation time is greater than or equal to 6s, the control unit controls the air conditioner to perform the heating mode.

The preset rotating speed is a preset rotating speed, and in order to avoid generating larger noise to influence the use experience, preferably, the preset rotating speed is a low rotating speed. For example, the preset rotation speed may be set to 400RPM, may be set to 800RPM, and may be set to any value of 400 to 800 RPM.
Further, the control unit compares the operation time of the air conditioner in the heating mode with a preset time, when the operation time of the air conditioner in the heating mode is more than or equal to the preset time, the control unit controls the compressor and the inner fan to be closed, and the air conditioner enters a standby mode; otherwise, the control unit controls the air conditioner to continue to execute the heating mode. The preset time is the running time of the preset air conditioner in the heating mode, the heating effect on the air duct inside the air conditioner is guaranteed during the preset time, and the influence of the overlong running time on the indoor environment temperature is avoided. For example, the preset time period may be set to 30s, may also be set to 180s, and may also be set to any value of 30 to 180 s.
