Specifically, when the indoor unit is in the operation state, the inner panel 3 is controlled to move to open the second area until the inner panel 3 moves to the bottom end of the inner panel and overlap with the first groove 4, at this time, the inner panel 3 and the outer panel 2 are stacked, and the filter screen cleaning member 8 can also play a cleaning role on the filter screen 7 during the movement of the inner panel 3, and the panel cleaning member 9 can play a cleaning role on the inner panel 3. Specifically, the gear is controlled by the motor to rotate anticlockwise so as to drive the rack 18 to move anticlockwise, and the inner panel 3 slides under the drive of the rack 18.
The cavity is formed between the inner layer panel 3 and the outer layer panel 2, when refrigeration operation is performed, cold air in the air duct and outside hot and humid air are not directly contacted on the same panel, and the temperature difference of two sides of the panel can be slowed down by the cavity, so that condensation water is not easy to form on the panel, and the condensation prevention function is achieved.
In the non-working mode, namely in standby or shutdown state, the inner layer panel 3 is controlled to move relative to the outer layer panel 2, so that the inner layer panel 3 and the outer layer panel 2 are relatively unfolded to completely cover the opening 5, dust in the air cannot enter the air conditioner to cause the blockage of the evaporator or influence the normal operation of the air conditioner, and the dustproof function is achieved.
When the air conditioner is in operation in an initial state, both the inner panel 3 and the outer panel 2 are at the front end of the panel body 1. After receiving the shutdown instruction, the motor in the panel body 1 starts to start to rotate clockwise, and drives the gear to drive the inner panel 3 to slide upwards. The filter screen cleaning piece 8 on the top end of the inner panel 3 is in direct contact with the surface of the filter screen 7 at the moment, the filter screen 7 is cleaned, the movement track of the filter screen cleaning piece 8 is consistent with the surface shape of the filter screen 7, and the cleaning efficiency is higher. Until the inner panel 3 slides to the top, the movement is stopped, the inner space of the air conditioner is in a nearly closed state, dust in the air is prevented from entering the inside, the evaporator is blocked or the normal operation of the air conditioner is influenced, and the dustproof function is realized.
In the maintenance mode, the outer layer panel 2 and the inner layer panel 3 are controlled to be stacked on the upper end of the opening 5 of the panel body 1. Specifically, the outer panel 2 can be directly pushed up by a technician, and the inner panel 3 can be synchronously lifted up under the action of the first groove 4 and slide upwards together, so that the opening of the opening panel body 1 is realized. The first limiting bulge 12 bypasses the second limiting bulge 13 and is used for limiting the position of the outer layer panel 2 when being lifted up when being lapped on the second limiting bulge 13, and the positions of the inner layer panel 3 and the outer layer panel 2 can be maintained to prevent the outer layer panel 2 from falling down uncontrollably and naturally after being lifted up.
In some embodiments, the indoor unit further has a cleaning mode, and the indoor unit can independently send out instructions to control the inner panel to reciprocate up and down, and the filter screen cleaning member 8 performs cleaning and dust removing operations in the process, and the specific control method is as follows: no matter the air conditioner is in a starting state or a closing state, if a user needs to clean the filter screen 7, the user can directly send a cleaning instruction, meanwhile, the motor in the panel body 1 starts to operate, the inner panel 3 is driven to slide up and down in a reciprocating manner, the filter screen cleaning piece 8 cleans the filter screen 7 at the same time, and after the cleaning is finished, the inner panel 3 returns to the initial state.
When the indoor unit is set to the cleaning mode, the specific position of the inner panel 3 is not considered, that is, when the indoor unit is in the operation mode and the inner panel 3 and the outer panel 2 are stacked, the indoor unit is switched to the cleaning mode, and the reciprocating movement of the inner panel 3 is controlled. Similarly, when the indoor unit is in a standby or off state and the inner panel 3 and the outer panel 2 are unfolded to cover the opening 5, the indoor unit can be in a cleaning mode to control the reciprocating movement of the inner panel 3.
Referring to fig. 1 to 10, an embodiment of the present application further provides an air conditioner including the indoor unit as described above, and an outdoor unit connected to the indoor unit through a connection pipe.
