The air conditioner indoor unit 100 with the air purification function of the embodiment sets a plurality of purification levels by optimizing the control mode of the driving mechanism 130, and is suitable for different working environments. The driving mechanism 130 may be configured to determine a corresponding purification level according to an air pollution parameter of an operating environment of the indoor unit 100 after acquiring a trigger signal for the air conditioner to enter the purification mode, and drive the purification assembly 140 to a specified height of the purification level to purify an air flow entering the indoor unit, where each purification level specifies a height of the purification assembly 140 from the air inlet 121.
The purification level may be set to three or more levels, for example, when purification is not needed, the purification assembly 140 may be located at a standby position, and as the air pollution parameter deteriorates, the height of the purification assembly 140 gradually decreases, so as to increase the proportion of purification performed on the air flow until the purification assembly completely descends to the air inlet 121.
The air conditioner indoor unit 100 with the air purifying function of the present embodiment is provided with an air quality detecting device 180. The air quality detecting device 180 is configured to detect an air pollution parameter of the working environment of the indoor unit 100 of the air conditioner. The trigger signal to enter the purge mode may include: an air pollution overrun signal reported by the air quality detection device 180, a start operation signal from a user, and a timing start signal. In this embodiment, the air quality detection device 180 may automatically output a trigger signal to start the purification when the air pollution parameter exceeds a preset purification start threshold. The purge activation threshold may be configured according to air quality.
After the purification is started, the driving mechanism 130 may further adjust the purification level according to the change of the air pollution parameter until the trigger condition for exiting the purification is satisfied. The trigger conditions for exiting the purge include any one or more of: a signal that the air pollution parameter decreases to a preset purge shutdown threshold; a signal of a purge time timeout; the air pollution parameter continues without improved signal. For example, after the working environment of the indoor unit 100 of the air conditioner has been improved by the purification, the purification can be exited. Alternatively, purging may be exited if the duration of purging exceeds a certain time. If the air pollution parameter continues to be improved or deteriorated during the cleaning process, indicating that the cleaning assembly 150 is not functioning, the cleaning process may be exited. After exiting the purge, the driving mechanism 130 drives the purge assembly 140 to ascend to the standby position.
The indoor unit fan 170 may determine a corresponding rotation speed adjustment scheme according to the purification grade; and the rotating speed is adjusted according to the rotating speed adjusting scheme of the indoor unit fan 170. A specific rotating speed adjusting scheme is as follows:
when the height of the purification assembly 140 from the air inlet 121 is greater than a first preset height, maintaining the rotating speed of the fan 170 of the indoor unit unchanged; when the height of the purification component 140 from the air inlet 121 is smaller than a first preset height and larger than a second preset height, increasing the rotating speed of the fan 170 of the indoor unit by a wind speed level; and when the height of the purification assembly 140 from the air inlet 121 is less than a second preset height, performing feedback control on the rotating speed of the fan 170 of the indoor unit according to the pipe temperature of the heat exchanger 160 of the indoor unit. The second preset height is smaller than the first preset height, and can be obtained by performing a pre-test according to the specification of the indoor unit 100, so as to ensure that the purification of the purification assembly 140 does not cause a high load.
In the purification process, the windage resistances of the airflows generated by the indoor fan 170 are obviously different, after the purification function is started, the airflows are filtered, and the attenuation of the heat exchange effect of the heat exchanger 160 is inevitably caused, so that the high load problem is easy to occur, when the height of the purification assembly 150 from the air inlet 121 of the indoor unit 100 in the embodiment is smaller than the second preset height, the target pipe temperature of the heat exchanger 160 pipe temperature of the indoor unit 100 can be set, the heat exchanger pipe temperature of the indoor unit 100 is detected in real time, the feedback control is performed on the indoor fan 170 according to the temperature difference between the detected pipe temperature and the target pipe temperature, so that the pipe temperature of the heat exchanger 160 is stabilized, and the high load problem caused by the overheating.
If the temperature of the heat exchanger 160 cannot be guaranteed to be stable by adjusting the indoor fan 170, the operating conditions of the compressor and the throttling device of the compression refrigeration cycle can be further adjusted. The compression refrigeration cycle realizes heat transfer by utilizing the compression phase change cycle of a refrigerant in a compressor, a condenser, an evaporator and a throttling device. In the air conditioner, the refrigeration system may further include a reversing valve to change the flow direction of the refrigerant, so that the indoor heat exchanger 160 may alternately serve as an evaporator or a condenser to perform a cooling or heating function. Since the compression refrigeration cycle in the air conditioner is well known to those skilled in the art, the operation principle and structure thereof will not be described again. In this embodiment, the compressor is an inverter compressor, and the throttle device is an electronic expansion valve with an adjustable opening degree. The specific control scheme may be:
when the air conditioner is in refrigeration operation, if the temperature of the heat exchanger 160 after purification is lower than the target temperature of the heat exchanger 160 and does not exceed the first temperature difference threshold (for example, 3 degrees), the feedback control can be performed on the fan 170 of the indoor unit 100 according to the difference, and the lower the temperature of the heat exchanger 160 is, the faster the rotation speed of the fan 170 of the indoor unit 100 is. If the increase of the rotating speed of the fan 170 of the indoor unit 100 cannot ensure that the temperature difference between the tube temperature of the heat exchanger 160 and the target tube temperature is within the first temperature difference threshold, the opening of the throttling device of the compression refrigeration cycle is increased, and if the temperature difference between the tube temperature of the heat exchanger 160 and the target tube temperature is within the second temperature difference threshold, the compressor is subjected to frequency reduction, so that the high load caused by the excessively low temperature of the heat exchanger 160 of the indoor unit is prevented.
When the air conditioner performs heating operation, if the temperature of the heat exchanger 160 after purification is higher than the target temperature of the heat exchanger and does not exceed a first temperature difference threshold (for example, 3 degrees), feedback control may be performed on the indoor fan 170 according to the difference, and the higher the temperature of the heat exchanger 160 is, the faster the rotation speed of the indoor fan 170 is. If the increase of the rotating speed of the indoor unit fan 170 cannot ensure that the temperature difference between the heat exchanger 160 and the target pipe temperature is within the first temperature difference threshold, the opening of the throttling device of the compression refrigeration cycle is increased, and if the temperature difference between the heat exchanger 160 and the target pipe temperature is still not ensured to be within the second temperature difference threshold, the frequency of the compressor is reduced, so that the high load caused by the overhigh temperature of the indoor unit heat exchanger 160 is prevented.
The first temperature difference threshold and the second temperature difference threshold may be configured according to the specification and the use requirement of the indoor unit heat exchanger 160, for example, the first temperature difference threshold is set to plus or minus 3 degrees celsius, and the second temperature difference threshold is set to plus or minus 5 degrees celsius.
The control process of the air conditioner indoor unit 100 in the above embodiment is further described below with reference to the control method of the air conditioner indoor unit 100 with an air purification function in this embodiment, and the control method of the air conditioner indoor unit 100 with an air purification function in this embodiment can be executed by the air conditioner indoor unit 100 with an air purification function described above, and meets the purification requirement by controlling the driving mechanism 130, the indoor unit fan 170, and the air quality detection device 180. Fig. 7 is a schematic diagram illustrating a control method of the indoor unit 100 of the air conditioner having an air cleaning function according to an embodiment of the present invention.

step S702, acquiring a trigger signal for the air conditioner to enter a purification mode; these trigger signals may include, but are not limited to: an air pollution overrun signal reported by the air quality detection device 180, a start operation signal from a user, and a timing start signal.
For the air pollution overrun signal, the air quality detection device 180 may trigger the air conditioner to enter the purification mode after detecting that the air pollution in the working environment of the air conditioner reaches a set overrun threshold (for example, each parameter overrun or the pollution level overrun).
For the start operation signal, the user can manually trigger the air conditioner to enter the purification mode through a remote controller or other air conditioner man-machine interaction interfaces.
For the timed start signal, the air conditioner may periodically perform purging according to the operation time, for example, accumulate the operation for 8 hours and start purging for 1 hour.
The trigger signal for the air conditioner to enter the purification mode can be set according to the requirement of the user on air purification. In this embodiment, the air quality detection device 180 may automatically output a trigger signal to start the purification when the air pollution parameter exceeds a preset purification start threshold.
Step S704, detecting air pollution parameters of the working environment of the indoor unit 100 of the air conditioner, and determining the purification grade corresponding to the air pollution parameters; the air quality detection device 180 can detect parameters such as index of micro-particles in the working environment, and accordingly determine the purification grade corresponding to the air pollution parameter. The height of each purification level purification assembly 140 from the air inlet 121;
in step S706, the driving mechanism 130 is controlled to drive the purifying assembly 140 to a specified height of the purifying level, so as to purify the airflow entering the indoor unit 100.
After the purification is started, the air pollution parameters can be continuously detected, and the purification grade is correspondingly adjusted according to the change of the air pollution parameters until the triggering condition for quitting the purification is met. The trigger conditions for exiting the purge include any one or more of: a signal that the air pollution parameter decreases to a preset purge shutdown threshold; a signal of a purge time timeout; the air pollution parameter continues without improved signal. For example, after the working environment of the indoor unit 100 of the air conditioner has been improved by the purification, the purification can be exited. Alternatively, purging may be exited if the duration of purging exceeds a certain time. If the air pollution parameter continues to be improved or deteriorated during the cleaning process, indicating that the cleaning assembly 150 is not functioning, the cleaning process may be exited.
In order to reduce the increase of the wind resistance caused by the cleaning component 150, after step S706, a corresponding rotating speed adjustment scheme of the indoor unit fan 170 may be determined according to the cleaning level; and adjusting the rotating speed of the fan 170 of the indoor unit according to the rotating speed adjusting scheme of the fan of the indoor unit. For example, when the height of the purification module 140 from the air inlet 121 is greater than a first preset height, the rotation speed of the fan 170 of the indoor unit is maintained unchanged; when the height of the purification component 140 from the air inlet 121 is smaller than a first preset height and larger than a second preset height, increasing the rotating speed of the fan 170 of the indoor unit by a wind speed level; and when the height of the purification assembly 140 from the air inlet 121 is less than a second preset height, performing feedback control on the rotating speed of the fan 170 of the indoor unit according to the pipe temperature of the heat exchanger 160 of the indoor unit. The second preset height is smaller than the first preset height, and can be obtained by performing a pre-test according to the specification of the indoor unit 100, so as to ensure that the purification of the purification assembly 140 does not cause a high load.
In the air conditioner of the embodiment, the driving mechanism 130 and the purifying assembly 140 connected with the driving mechanism 130 are arranged in the indoor unit 100, the purifying assembly 140 is driven by the driving mechanism 130 to move up and down, and air flow entering the indoor unit 100 is purified according to the air quality, so that the air quality of the indoor environment is improved; in addition, when the ambient air quality is good and the air purification assembly 140 is not needed to be used for purifying air, the purification assembly 140 can be driven by the driving mechanism 130 to be ejected upwards to expose the air inlet 121, so that the expansion and use flexibility of the functions of the indoor unit 100 of the air conditioner are realized, and the purification degree of the air flow purified by the purification assembly 140 can be changed by adjusting the height of the purification assembly 140 relative to the air inlet 121, so that the requirements of air purification are met, the wind resistance generated by the purification assembly 140 is reduced as much as possible, the expansion and use flexibility of the functions of the indoor unit 100 of the air conditioner are realized, and the normal temperature regulation function of the air conditioner is prevented from.
