- The present disclosure relates to an air conditioner.
- Air conditioners are apparatuses that maintain air in a door space to the most proper state according to use and purpose thereof.
- Such an air conditioner may be classified into an upright type, a wall-mounted type, or a ceiling type according to its installation position. The upright air conditioner may be understood as a type of air conditioner, which is installed to be erected in an indoor space, the wall-mounted type air conditioner may be understood as a type of air conditioner, which is installed to be attached to a wall surface. Also, the ceiling type air conditioner may be understood as a type of air conditioner, which is installed on a ceiling.
- The air conditioner may be a cooler for cooling a predetermined space, a heater for hating a predetermined space, an air conditioner for cooling or heating a predetermined space, and a cleaner for cleaning air within a predetermined space. The function of the air conditioner may be determined according to a type of an air conditioning unit installed in the air conditioner.
- The air conditioner may include a compressor, a condenser, an expansion device, and an evaporator to drive a refrigerant cycle in which compression, condensation, expansion, and evaporation processes of a refrigerant are performed, thereby cooling or heating a predetermined space.
- The air conditioner may include an electric heater, and current may be applied to the electric heater to heat the predetermined space.

- Korean Patent Publication No.
10-06609681 (Published on December 26, 2006 - Embodiments provide an air conditioner that is capable of preventing a filter assembly from being incorrectly mounted.
- Embodiments also provide an air conditioner in which a filter assembly reliably moves to a set position.
- Embodiments also provide an air conditioner in which a user is capable of easily placing a filter assembly.
- In one embodiment, an air conditioner includes: a filter assembly disposed in an air suction hole that is lengthily defined in the air conditioner in a left-right direction; and a pair of moving mechanisms configured to allow the filter assembly to move forward and backward in a direction crossing a longitudinal direction of the filter assembly.
- The pair of moving mechanisms may include: a motor; and a rack configured to move forward and backward by the motor.
- The filter assembly may be withdrawn forward from the air conditioner when the motor operates, and the filter assembly may be inserted into the air conditioner when the motor operates reversely.
- The air conditioner may further include: a case in which the filter assembly is accommodated; a front panel disposed on the case; and a driving mechanism configured to elevate 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 at which the front panel covers a front surface of the filter assembly; and a second position at 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 moving mechanisms may allow the filter assembly to move forward and backward while the front panel is disposed at the second position.
- A front discharge hole, which is opened in a front-rear direction, may be defined in a lower portion of a front surface of the case.
- Each of the first position and the second position may be a position at which the front panel covers the front discharge hole.
- The plurality of positions may further include a third position at which the front panel opens the front discharge hole and covers the front surface of the filter assembly.
- The air conditioner may further include an accommodation body in which the air suction hole is defined, and the filter assembly is accommodated.
- Each of front and top surfaces of the accommodation body may be opened, and the filter assembly may be withdrawn forward or upward.
- The air conditioner may further include a carrier on which the filter assembly is placed and to which the moving mechanism is connected.
- When the carrier operates in a backward movement mode, the filter assembly may move backward so that the filter assembly is accommodated in the accommodation body, and the filter assembly may reliably move to a set position within the accommodation body.
- An opening through which air passes may be defined in a lower portion of the accommodation body. The carrier may be movably disposed in the carrier. A length of the opening in a front-rear direction may be greater than a length of the carrier in the front-rear direction.
- The air conditioner may further include a supply terminal disposed on the accommodation body.
- The filter assembly may include an electric filter. The electric filter may include an electrode terminal that is connected to or disconnected from the supply terminal.
- The moving mechanism may be connected to the carrier to allow the carrier to move backward.
- When the moving mechanism moves backward, the moving mechanism may allow the carrier to move to a connection position at which the electrode terminal is connected to the supply terminal. The connection position may be the set position and also a normal mounting position or a mounting completion position at which the mounting of the filter assembly is normally completed.
- The moving mechanism may further include a driving gear connected to a motor and engaged with a rack. The rack may be disposed on a gear member connected to the carrier.
- In another embodiment, an air conditioner may include: a magnet disposed on a filter assembly; a magnet sensor disposed on a carrier to sense the magnet; and a controller configured to control a moving mechanism to a backward movement mode when the magnet is sensed by the magnet sensor.
- When a user places the filter assembly in a direction opposite to a predetermined direction such as the placing of the filter assembly upside down in a front-rear direction or a left-right direction, in the air conditioner, the filter assembly may stand by without moving backward, incorrect mounting of the filter assembly may be prevented. Also, an operation of the air conditioner in the state in which the filter assembly is incorrectly mounted may be minimized.
- The air conditioner may further include a magnetic body that is attracted to the magnet. The magnetic body may be a paramagnetic body. The carrier may be a nonmagnetic body.
- The moving mechanism may further include a sliding guide that guides the carrier.
- An opening may be defined between the gear member and the carrier. The opening may be opened in the forward and backward movement direction of the carrier.
- The sliding guide may include a guide body through which the opening is guided, and the guide body may guide the forward and backward movement of the carrier and the driven gear.
- The sliding guide may further include a guide rail spaced apart from the guide body to guide a lower end of the gear member.
- The carrier may include a seating body on which the filter assembly is placed and a stopper extending from the seating body and allowing the filter assembly to be hooked in a rear direction.
- When the user performs a simple operation of placing a portion of the filter assembly at 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 whole of the filter assembly into the accommodation body, and thus, the user may more easily mount the filter assembly.
- The carrier may further include a sensor accommodation body in which the magnet sensor is accommodated.
- In this case, the carrier may also function to carry the filter assembly and support the magnet sensor, and the number of components of the air conditioner may be minimized.
- The sensor accommodation body may be disposed below the seating body.
- A size of the seating body may be greater than a size of the sensor accommodation body.
- The air conditioner may further include a magnetic body disposed on a rear surface of the stopper and attracted to the magnet.
- According to the embodiment, the pair of moving mechanisms may allow the filter assembly to move forward and backward, and thus, the entire filter assembly that is elongated in the left-right direction may more stably move.
- Also, when the filter assembly is placed at the position at which the magnet sensor senses the magnet, the carrier may allow the filter assembly to move backward, thereby preventing the filter assembly from being incorrectly mounted. Also, the operation of the air conditioner in the state in which the filter assembly is incorrectly mounted may be minimized.
- Also, in the backward movement mode of the carrier, the carrier may allow the filter assembly to move to the set position within the accommodation body and allow the filter assembly to the set position with the higher reliability than when the user places the filter assembly at the set position.
- When the user performs the simple operation of placing the portion of the filter assembly at 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 whole of the filter assembly into the accommodation body, and thus, the user may more easily mount the filter assembly.
- Also, since the carrier is movably disposed in the opening, it may be more compact when all of the carrier move upward and downward from the opening.
- Also, since the carrier includes the seating body and the sensor accommodation body, the carrier may also function to carry the filter assembly and support the magnet sensor, and the number of components of the air conditioner may be minimized.
- Also, the sensor accommodation body is disposed under the seating body so that the magnet sensor and the sensor accommodation body are protected by the seating body.
- Also, the size of the seating body may be greater than that of the sensor accommodation body, and thus, the foreign substances such as the dust may be minimized to be accumulated on the surface of the magnet sensor or between the sensor accommodation body and the magnet sensor, and the magnet sensor may be maintained in the cleaned clean.
- Also, the carrier may be made of the nonmagnetic material, and the sensing accuracy of the magnet sensor may be high.
- Also, the motor may be mounted on the sliding guide that guides the carrier, and thus, the number of components may be minimized when the motor is mounted on the separate motor mounter.
- Also, 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 member and the carrier may be guided by one guide body, and the number of components may be minimized to simply the structure when compared to the case in which the gear member and the carrier may be respectively guided to the different guide bodies.
- Also, since the gear member is guided to the sliding guide and the guide rail, the gear member and the carrier may be more slidably move.
- Also, the attractive force is applied between the magnet and the magnet disposed on the carrier to assist the location of the filter assembly, on which the magnet is disposed, at the fixed position on the carrier to prevent the filter assembly from being mislocated when the carrier moves.
- Also, the magnetic body may be made of the paramagnetic body, and thus, the malfunction of the magnet sensor may be minimized.
- Also, the stopper may determine the fixed of the filter assembly and limit the excessive insertion of the filter assembly.
- Also, the magnetic body may be disposed on the rear surface of the stopper, and thus, the filter assembly on which the magnet is mounted may be induced to be hooked with the front surface of the stopper.
- Also, in the backward movement mode of the moving mechanism, the moving mechanism may allow the carrier and the filter assembly to move backward to the connection position at which the electrode terminal is connected to the supply terminal, and the air conditioner may connect the electrode terminal to the supply terminal so that the air is cleaned by the electric filter.
