Compared with the scheme that the purification assembly 150 is directly driven by the arc-shaped rack 143 and the first guide rail 145-3 is adopted to provide a sliding track for the purification assembly 150, the space occupied by the connection rod 146 for driving the purification assembly 150 to move in cooperation with the irregular second guide rail 145-7 is smaller, and the internal space of the indoor unit 100 of the air conditioner can be saved.
In order to clearly and intuitively understand that the purification assembly 150 is driven by the arc-shaped rack 143, and the scheme of providing the sliding track for the purification assembly 150 by the first guide rail 145-3 is different from the scheme of driving the purification assembly 150 by the arc-shaped rack 143 through the connecting rod 146 to match the movement of the second guide rail 145-7 with an irregular shape, figure 9 shows the path of the irregularly shaped second guide rail 145-7 and the curved first guide rail 145-3, as shown in fig. 9, a is a path of the irregular-shaped second guide rail 145-7 formed by connecting the first arc-shaped section 145-7-1 and the second arc-shaped section 145-7-2 having a different arc from the first arc-shaped section 145-7-1, B is a path of the first guide rail 145-3 having an arc shape, and the irregular-shaped second guide rail 145-7 is positioned outside the first guide rail 145-3 having an arc shape.
Accordingly, if the purification assembly 150 is directly moved by the arc-shaped rack 143 along the arc-shaped first guide rail 145-3, the movement trace of the purification assembly 150 is located at the outer side, and if the purification assembly 150 is moved by the connecting rod 146, the movement trace of the purification assembly 150 is located at the inner side. Therefore, the cleaning assembly 150 requires less space to move along the irregular-shaped second guide 145-7 by the connecting rod 146, and can make more internal space of the indoor unit 100, without increasing the volume of the indoor unit 100, and provide enough space for the arrangement of the heat exchanger 160, the fan 170 and other components while arranging the driving device 140 and the cleaning assembly 150.
As shown in fig. 1, 4, 6 and 7, the cleaning assembly 150 can be detachably connected to the driving device 140, so as to facilitate cleaning and replacement of the cleaning assembly 150.
The purification assembly 150 can include a bracket and a purification module 151 disposed on the bracket. The shape and size of the purification module 151 may be determined according to the size of the air inlet 121 and the inner space of the indoor unit 100, and for example, the purification module 151 may have an arc shape.
The electrostatic absorption module can adsorb electrified PM2.5 particulate matter, PM2.5 particulate matter in the high-efficient filtration environment, plasma purification module can catch the non-plasma of special use, high-efficient bacterium, virus of killing, and decompose into trace H2O, CO2 entering air, anion generation module can release the anion in to the air, form oxygen anion, high-efficient dust removal sterilization, air-purifying, active air molecule simultaneously, improve human lung function, promote metabolism.
The bracket may include two connecting portions 152 disposed oppositely, and in the scheme that the arc-shaped rack 143 directly drives the purifying assembly 150 to slide along the arc-shaped guide rail, the two connecting portions 152 are directly connected to the corresponding arc-shaped rack 143.
In the case where the arc-shaped rack 143 moves the purification assembly 150 along the irregularly-shaped second guide rail 145-7 by the link 146, the two connection portions 152 are rotatably connected to the corresponding links 146. The purification module 151 is disposed on the connection portion 152 between the two connection portions 152. Specifically, two connecting portions 152 may be oppositely disposed at two opposite end edges of the purification module 151, a first end of the connecting portion 152 is rotatably connected to a second end of the link 146, and a second end of the connecting portion 152 is slidably engaged with the second guide rail 145-7.
The cleaning assembly 150 is driven by the driving device 140 to move between the inner side of the front panel 130 and the inner side of the air inlet 121, and when the cleaning function is not started, the cleaning assembly 150 moves to the inner side of the front panel 130 and is in a non-cleaning position; after the cleaning function is turned on, the cleaning assembly 150 is driven by the driving device to move to the inner side of the air inlet 121 to completely shield the air inlet 121, and is located at the cleaning position to clean the air entering the indoor unit 100.
Because the purification assembly 150 is in purification position and when not purifying the position, the windage that indoor set fan produced the air current is obviously different, after opening purification performance, the air current filters, must lead to the heat transfer effect attenuation through heat exchanger 160, appears high load problem easily, can carry out corresponding control according to the operation mode of air conditioner, makes the air conditioner reduce the influence to the normal refrigeration of air conditioner or heating function when purifying.
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.
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 cooling operation, if the temperature of the heat exchanger tube after purification is higher than the target tube temperature and does not exceed the 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 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.
