Then, when the fan 80 starts to operate, the room air is drawn into the tank through the air inlets 70a, 70b, 70c, when the air passes through the side filters 21, 22, and the lower filter group 230 of the air cleaner, The air that is drawn in is purified. 0 In detail, via the base 50 The air drawn in before the air inlet 70a is continuously purified through the filter state 231, the second transition 232, and the third filter 233; the air drawn in through the air inlets 7〇b, 70c of the front case 70 When the side filter states 210, 220 are passed, the main purpose is to clean the air, because the indoor unit is closed at the side inlet blades 77a, 77b, and only the lower blades 54 are opened for drawing. The air is operated by the front air inlet 70a, and even fine dust particles are removed by the lower filter group 230 to clean the air discharged to the room. Second, via the filters 210, 22〇, 231, 232, When the 233 purified air passes through the photocatalyst plasma air purifying device 24 in front of the fan 80, dust and odor particles are ionized and collected. The cleaned gas is blown to the heat exchanger 9 by the fan 8〇, The refrigerant flowing through the heat exchanger is subjected to a heat exchange process, and is discharged to the room via the air outlets 72a, 72b, 72c in a cooled or heated state to cool or heat the room. When the air cleaner is used for a time, if the debris such as dust accumulates in the transition device 23 232, 233 and the side filters 210, 220 of the lower filter group 230, the user can conveniently open the front panel 100 to the front case 70. 22 1255327 The direction of the dough is taken out of the filter 231, 232, 233 or side of the lower filter group 230, the horse filter 210, 220 〇 ^ Then, insert the cleaned or new transition device, # move off the front 100. In addition, even When a device such as the heat exchanger 90 or the fan 80 is to be repaired or cleaned, the heat exchanger 90 or the fan 80 can be repaired or cleaned through the opening 71c in a state where the front panel 100 is opened. ~ - Secondly, if the manufacturer wants to change the color of the front face of the button (10), the front color of the room can be easily and easily changed by replacing the existing color plate 12 on the front panel 100 with a new color plate. As described above, the indoor unit of the air conditioner of the present invention has the following advantages: First, the three side air inlets and outlets of the other cabinets reduce the sound of the air inlet, and supply the heat exchanged and clean air to each of them. direction. Second, the air cleaner is easy to handle and does not pose a risk of injury to adjacent components. The repair or cleaning of the second 'hot father's brain or fan is easy because the heat exchange of the tank or the repair or cleaning of the fan can be performed with the front panel open. Fourth, the heat exchanger and other components are hidden behind the cabinet and the front of the front panel. The front panel forms the exterior of the front of the indoor unit, which improves the appearance and allows the front surface to be easily replaced. ^5 When the indoor unit is not operating, the intrusion of the debris can be avoided by opening/closing the blade of the air inlet and outlet; it is easy to form a unit when the side outlet vane and the side inlet vane 23 ί255327. Simple structure with a motor to open/close
The upper side (4) is made up of air ώ σ, and it is spread to the fan. This air is overloaded by the motor that can avoid driving the fan, so that the second 上 exit on the next day is smoothly discharged. Moreover, ^^ who is familiar with this technology can make various modifications and changes, therefore, where the corrections and reliance (4) are specific _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _Changes are all covered by the invention.
