Also, the operation of the air conditioner in the state where the filter assembly is incorrectly mounted can be minimized.

Also, in the backward moving mode of the conveyor, the conveyor can allow the filter assembly to move to the set position within the housing body and allow the filter assembly to reach the set position more reliably than when the user places the filter assembly in the set position.

When the user performs the simple operation of placing the part of the filter assembly in a fixed position on the carrier, since the carrier allows the filter assembly to move to the set position, the user may not need to insert the entire filter assembly into the housing body and therefore the user can more easily mount the filter assembly.

Also, since the carrier is movably disposed in the opening, it can be more compact when the entire carrier moves up and down from the opening.

Furthermore, since the carrier includes the seat body and the sensor housing body, the carrier can also function to carry the filter assembly and support the magnetic sensor, and the number of components of the air conditioner can be minimized.

Furthermore, the sensor housing body is disposed below the seat body, so that the magnetic sensor and the sensor housing body are protected by the seat body.

In addition, the size of the seat body can be larger than that of the sensor housing body, and thus the accumulation of foreign substances, such as dust, on the surface of the magnetic sensor or between the housing body can be minimized. of the sensor and the magnetic sensor, and the magnetic sensor can be kept clean and clean.

In addition, the carrier can be made of non-magnetic material, and the detection accuracy of the magnetic sensor can be high.

Also, the motor can be mounted on the slider that guides the conveyor, and therefore the number of components can be minimized when the motor is mounted on the separate motor mount.

Furthermore, since the opening defined between the gear member and the carrier is guided by the guide body of the slider, each of the gear members and the carrier can be guided by one guide body, and the number of components can be minimized to just the structure as compared to the case where the gear element and the carrier can be respectively guided to the different guide bodies.

Also, since the gear member is guided toward the slider and the guide rail, the gear member and the conveyor can move more sliderly.

In addition, the attractive force is applied between the magnet and the magnet provided on the carrier to help position the filter assembly, on which the magnet is provided, in the fixed position on the carrier to prevent the filter assembly misplaced when the carrier is moving.

Also, the magnetic body can be made of paramagnetic body, and therefore the malfunction of the magnetic sensor can be minimized.

Furthermore, the stopper can determine the fixation of the filter assembly and limit the excessive insertion of the filter assembly.

Furthermore, the magnetic body may be disposed on the rear surface of the stopper, and thus the filter assembly on which the magnet is mounted can be induced to engage with the front surface of the stopper.

In addition, in the backward movement mode of the movement mechanism, the movement mechanism can allow the conveyor and the filter assembly to move backward to the connection position where the terminal is connected to the power terminal, and the air conditioner can connect the terminal to the power terminal for the electric filter to clean the air.
