So that the purification assembly 130 can rotate between a position covering the air inlet 111 and a position exposing the air inlet 111 with the transverse direction of the housing 110 as a rotation axis.
The purification component 130 is driven by the driving mechanism 120 to rotate between a position covering the air inlet 111 and a position exposing the air inlet 111 by taking the transverse direction of the housing 110 as a rotating shaft, and when the purification function is not started, the purification component 130 is driven by the driving mechanism 120 to be ejected upwards from the air inlet 111 and is positioned at a non-purification position; after the cleaning function is activated, the cleaning assembly 130 is driven by the driving mechanism 120 to cover the air inlet 111 and is in a cleaning position to clean the air entering the indoor unit 100.
Because the purification assembly 130 is when purifying the position and not purifying the position, the windage that the indoor set fan produced the air current is obviously different, after opening purification performance, the air current filters, inevitably leads to the heat transfer effect attenuation through the heat exchanger, appears the high load problem easily, can carry out corresponding control according to the operation mode of air conditioner, makes the air conditioner reduce the normal refrigeration or the influence of heating the function to the air conditioner when purifying.
In some alternative embodiments, the air conditioner includes a refrigeration system including a heat exchanger provided in the indoor unit 100 to exchange heat with air entering the indoor unit, a tube temperature sensor, and a controller. The tube temperature sensor is configured to detect a tube temperature of the heat exchanger of the indoor unit 100. The controller is configured to control the driving mechanism 120 to move the purification assembly 150 to the purification position after acquiring a trigger signal for the air conditioner to enter the purification mode, so as to purify the air flow entering the indoor unit 100, and to perform feedback control on the refrigeration system according to the target pipe temperature in the purification mode set by the pipe temperature of the heat exchanger of the indoor unit 100 when entering the purification mode.
The refrigerating system also comprises an indoor unit fan, a compressor and a throttling device. The controller can also carry out corresponding control according to the operation mode of the air conditioner, so that the influence on the normal refrigeration or heating function of the air conditioner is reduced when the air conditioner is purified. The controller may be configured to: acquiring a tube temperature sensor to detect the tube temperature of a heat exchanger of the indoor unit in real time, and calculating the difference value between the tube temperature sensor and the target tube temperature; when the difference value is smaller than a preset first temperature difference threshold value, performing feedback control on a fan of the indoor unit according to the difference value; increasing the opening degree of a throttle device of the compression refrigeration cycle when the difference value is greater than or equal to the first temperature difference threshold value and less than the second temperature difference threshold value; and when the difference value is greater than or equal to a second temperature difference threshold value, reducing the frequency of the compressor of the compression refrigeration cycle, wherein the second temperature difference threshold value is greater than the first temperature difference threshold value.
For example, after the purification function is turned on, a target tube temperature of the heat exchanger tube temperature of the indoor unit 100 may be set, the heat exchanger tube temperature of the indoor unit 100 may be detected in real time, and the refrigeration system of the air conditioner may be feedback-controlled according to a temperature difference between the detected tube temperature and the target tube temperature.
The target tube temperature can be set according to the heat exchanger tube temperature of the indoor unit 100 when the indoor unit enters the purification mode, in this embodiment, the default position of the purification assembly 130 is a position where purification is not performed, when purification is started, the air conditioner is stable in a normal refrigeration or heating state, and at the moment, the heat exchanger tube temperature of the indoor unit 100 is the normal state temperature of the air conditioner in the current refrigeration mode or heating mode, so that the target tube temperature is set according to the heat exchanger tube temperature at the moment, and the influence on refrigeration and heating after the air conditioner is started and purified can be ensured to be small.
One specific control method is as follows:
when the air conditioner operates in a cooling mode, if the temperature of the heat exchanger tube after purification is lower than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the fan of the indoor unit 100 can be subjected to feedback control according to the difference, and the lower the temperature of the heat exchanger tube is, the faster the fan rotating speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value with the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured to be maintained within the second temperature difference threshold value with the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the excessively low temperature of the heat exchanger of the indoor unit 100 is prevented.
When the air conditioner performs heating operation, if the temperature of the heat exchanger tube after purification is higher than the target tube temperature and does not exceed a first temperature difference threshold (for example, 3 degrees), the feedback control can be performed on the fan of the indoor unit 100 according to the difference, and the higher the temperature of the heat exchanger tube is, the faster the fan rotation speed of the indoor unit 100 is. If the increase of the rotating speed of the fan of the indoor unit 100 cannot ensure that the temperature of the heat exchanger tube is maintained within the first temperature difference threshold value from the target tube temperature, the opening of a throttling device of the compression refrigeration cycle is increased, and if the temperature of the heat exchanger tube cannot be ensured within the second temperature difference threshold value from the target tube temperature, the frequency of the compressor is reduced, so that the high load caused by the overhigh temperature of the heat exchanger of the indoor unit 100 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 heat exchanger of the indoor unit 100, 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.
