The invention also provides an air conditioner into which a user can easily attach a filter assembly.

According to the invention, the air conditioner comprises: a filter assembly disposed in an air suction port that is defined lengthwise on the air conditioner in a left to right direction; and a pair of movement mechanisms configured to allow the filter assembly to move back and forth in a direction that intersects a longitudinal direction of the filter assembly,

where the pair of mobile mechanisms comprises:

a motor; and

a rack configured to move forward and backward by the motor;

wherein the filter assembly is adapted to be removed forward from the air conditioner when the engine is running, and

The filter assembly is adapted to be inserted into the air conditioner when the engine runs in reverse,

whereby the air conditioner further comprises a support or conveyor on which the filter assembly is placed, wherein the movement mechanism is connected to the conveyor to allow the conveyor to move back and forth,

wherein the air conditioner further comprises a housing body in which the air suction hole is defined and the filter assembly is housed,

wherein the air conditioner further comprises a supply terminal disposed in the housing body,

wherein the filter assembly comprises an electrical filter,

The electrical filter comprises an electrode terminal that is connected or disconnected from the supply terminal, and

When the moving mechanism is moved rearwardly, the moving mechanism is configured to allow the carrier to move rearwardly to a connection position in which the electrode terminal is connected to the supply terminal.

The air conditioner may further include: a box in which the filter assembly is housed; a front panel arranged on the box; and a drive mechanism configured to raise the front panel to a plurality of positions.

The pair of moving mechanisms and the driving mechanism may be interlocked with each other.

The plurality of positions may include: a first position in which the front panel covers a front surface of the filter assembly; and a second position in which the front panel exposes the front surface of the filter assembly.

The second position may be relatively lower than the first position.

The pair of movement mechanisms may allow the filter assembly to move back and forth while the front panel is arranged in the second position.

A front discharge port, opening in a front-rear direction, may be defined in a lower portion of a front surface of the box.

Each of the first position and the second position may be a position in which the front panel covers the front discharge port.

The plurality of positions may further include a third position in which the front panel opens the front discharge port and covers the front surface of the filter assembly.

The air conditioner may further include a conveyor on which the filter assembly is placed and to which the moving mechanism is connected.

When the conveyor operates in a rearward motion mode, the filter assembly can be moved rearwardly so that the filter assembly fits into the housing body, and the filter assembly can be reliably moved to a set position within of the housing body.

Additionally, when the filter assembly is placed in the position where the magnetic sensor detects the magnet, the conveyor can allow the filter assembly to move rearward, thereby preventing the filter assembly from being mounted incorrectly. In addition, the operation of the air conditioner can be minimized in the state in which the filter assembly is incorrectly mounted.

Furthermore, in the rearward movement 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 filter assembly part in a fixed position on the conveyor, since the conveyor 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.

Furthermore, since the conveyor is movably arranged in the opening, it can be more compact when the entire conveyor moves up and down from the opening.

Furthermore, since the conveyor includes the seat body and the sensor housing body, the conveyor can also function to transport 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 arranged below the seat body, so that the magnetic sensor and the sensor housing body are protected by the seat body.

Furthermore, the size of the seat body can be larger than that of the sensor housing body and, therefore, 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 conveyor can be made of non-magnetic material, and the detection accuracy of the magnetic sensor can be high.

Furthermore, the motor can be mounted on the slide guide that guides the conveyor and therefore the number of components can be minimized when the motor is mounted on the separate motor mounter.

Furthermore, since the opening defined between the gear member and the carrier is guided by the guide body of the sliding guide, each of the gear members and the carrier may be guided by a guide body, and the number of components can be minimized to simply the structure compared to the case where the gear element and the conveyor can be guided respectively to the different guide bodies.

Furthermore, since the gear element is guided towards the sliding guide and the guide rail, the gear element and the conveyor can move more slidingly.

Furthermore, the attractive force is applied between the magnet and the magnet arranged on the conveyor to assist in placing the filter assembly, in which the magnet is arranged, in the fixed position on the conveyor to prevent the filter assembly be positioned incorrectly when the conveyor moves.

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

Additionally, the stop can determine the fixation of the filter assembly and limit excessive insertion of the filter assembly. Furthermore, the magnetic body may be disposed on the rear surface of the stopper and, therefore, the filter assembly on which the magnet is mounted may be induced to engage with the front surface of the stopper.

Furthermore, in the backward movement mode of the movement mechanism, the movement mechanism may allow the conveyor and filter assembly to move backward to the connection position in which the terminal is connected to the feed terminal, and The air conditioner can connect the terminal to the power terminal for the electric filter to clean the air.
