Description

Air conditioner
The invention is a divisional application of the following patent applications: application number: 202010075550.5, filing date: 22 days 1 month 2020, invention name: air conditioner
Technical Field
The present invention relates to an air conditioner, and more particularly, to an air conditioner capable of cleaning a filter.
Background
An air conditioner is a device for maintaining indoor air in an optimal state according to the purpose and purpose.
Air conditioners can be classified as cabinet type, wall-hanging type or ceiling type depending on the installation location. The cabinet type indoor unit is understood to be an air conditioner of a type installed to stand in an indoor space, and the wall-mounted type indoor unit is understood to be an air conditioner of a type installed to be attached to a wall surface. The ceiling-mounted indoor unit is understood to be an air conditioner of a type mounted on a ceiling.
The air conditioner may be an air conditioner for cooling a predetermined space, a heating machine for heating the predetermined space, a cooling and heating air conditioner for cooling or heating the predetermined space, a purifier for purifying air in the predetermined space, etc., and the function of such an air conditioner may be determined according to the type of an air conditioning unit installed inside the air conditioner.
The air conditioner may include a compressor, a condenser, an expansion device, and an evaporator, and may drive a refrigeration cycle performing compression, condensation, expansion, and evaporation processes of a refrigerant to cool or heat the predetermined space.
The air conditioner may include an electric heater, and a current may be applied to the electric heater to heat the predetermined space.
The air conditioner may include a purifying unit such as a filter unit, etc., and may purify air of the predetermined space.
In the air conditioner, a filter that filters dust in air may be provided, and a cleaning kit for cleaning the filter may be provided.
An example of an air conditioner having the filter and the cleaning kit as described above is disclosed in korean laid-open patent publication No. 10-2009-0044786A (published 5/7/2009), and this air conditioner includes: a moving cleaning kit configured to clean foreign materials in the filter as the filter moves; and a cleaning moving tool connected to the moving cleaning kit to move the moving cleaning kit in a left-right direction, the moving cleaning kit including a cleaning kit body connected to move by the moving tool and a brush formed to protrude from the cleaning kit body toward the filter.
However, in the air conditioner having the moving cleaning kit as described above, since the brush and the moving cleaning kit move, dust separated from the brush or the filter may be scattered around the filter during the movement of the brush along the filter, and thus the cleaning around the filter may not be maintained. In addition, since the cleaning kit body for the movable brush requires an additional space between the air suction part and the filter in order to provide the movable cleaning kit, the space utilization rate inside the air conditioner is low, and there is a problem in that the air conditioner is difficult to compact.
As another example of an air conditioner having the filter and the cleaning kit as described above, in japanese laid-open patent publication JP2005-300154A (published on 10/27 2005), the filter reciprocates inside the main body casing by means of a sliding device, and includes a filter cleaning portion that contacts the filter along a moving path of the filter, the filter cleaning portion including a lower cover, an upper cover, and a pair of brushes, foreign matter in the filter being separated from the filter during passage of the filter moved by the sliding device by the pair of brushes, so that it may be stored in a space between the lower cover and the upper cover.
However, as described above, a portion of the filter moved by the sliding device can be pulled out to the outside of the air conditioner to clean the entire filter, and there is a problem in that the portion located at the outside of the air conditioner may be damaged or contaminated.

Disclosure of Invention
The invention aims to provide an air conditioner which can minimize pollution or damage of a filter when cleaning the filter and has high internal space utilization rate.
Another object of the present invention is to provide an air conditioner that can minimize damage to other components by a filter.
An air conditioner according to an embodiment of the present invention may include a prefilter, a roller rotating mechanism, and a brush unit. The air conditioner may include a filter housing.
The prefilter may be oriented toward an air intake for intake air and may be a flexible material. The prefilter is capable of engaging the roller. When the roller rotates, the prefilter can move along the outer circumference of the roller inside the filter housing and can be in contact with the brush unit.
The roller can support one side of the prefilter in the longitudinal direction and can move the prefilter left and right. The roller is rotatably accommodated inside the filter housing.
The roller rotation mechanism may rotate the roller.
The brush unit may be disposed at the filter housing. The brush unit may be configured to be capable of contacting the prefilter when the roller rotates. The brush unit can be spaced apart from the roller rotating mechanism.
The air conditioner can maintain the cleaning around the prefilter and does not require a space for moving the brush unit, compared to the case where the position of the prefilter is fixed and the brush unit is moved, so that the space utilization rate inside the air conditioner can be improved.
Further, when the prefilter is cleaned, the prefilter moves inside the filter housing and is not pulled out from the filter housing, so that the space utilization efficiency inside the air conditioner is high, the damage of the prefilter can be minimized, and the possibility of damage of other components arranged inside the air conditioner due to the prefilter can be minimized.
The filter housing, the roller, the prefilter, and the brush unit may constitute a filter assembly, which can be drawn out of the air conditioner to the outside together with the filter housing, and which can be easily managed by a user or operator.
The filter housing may have an external inlet formed therein as an air suction port for sucking air and an internal outlet formed therein as an air discharge port for discharging air.
To move the prefilter with the roller, the roller may include a drive gear, and the prefilter may include a driven gear engaged with the drive gear.
The brush unit may be configured to contact the prefilter when the roller rotates. The brush unit may be disposed adjacent to the roller.
The air conditioner may further include an electrostatic filter disposed between the pre-filter and the filter housing and spaced apart from the roller. The roller does not interfere with the electrostatic filter when the roller rotates, and damage to the electrostatic filter can be minimized.
The electrostatic filter may constitute the filter assembly together with the filter housing, rollers, prefilters and brush units. The electrostatic filter can be drawn out of the air conditioner to the outside together with the roller, the prefilter, the brush unit, and the filter housing, and a user or operator can wash the electrostatic filter with a washing solution such as water.
The prefilter is movable between the filter housing and an electrostatic filter, an outer surface of the electrostatic filter and an inner surface of the filter housing being capable of forming a channel through which the prefilter is movable.
The thickness in the air flow direction in the electrostatic filter may be less than or equal to the diameter of the roller. When the thickness of the electrostatic filter is greater than the diameter of the roller, a portion of the prefilter located between the electrostatic filter and the filter housing may protrude. On the other hand, as described above, when the thickness of the electrostatic filter is less than or equal to the diameter of the roller, the portion of the prefilter located between the electrostatic filter and the filter housing can be spread out in a flat state as much as possible.
A guide body may be formed in the filter housing, the guide body guiding the prefilter to move between the electrostatic filter and the lower housing. The portion of the prefilter that moves along the outer circumference of the roller may be guided by the guide body between the electrostatic filter and the lower case, and the prefilter may move smoothly and stably to the maximum extent.
The air conditioner may further include a filter guide guiding the prefilter to move along the outer circumference of the roller when the roller rotates, and the filter guide may be formed with a guide surface contacting the prefilter.
At least a portion of the filter guides are arcuate, and the radius of the arcuate portion may be greater than the radius of the roller.
The filter guide may include first and second guides spaced apart from each other by a distance greater than a diameter of the roller, and a third guide connecting the first and second guides.
The portion of the prefilter located between the filter guide and the roller may be guided and curved in an arc shape by the roller and the guide surface, respectively, and may minimize malfunction of the prefilter and stably move the prefilter.
The air conditioner may further include a dust tub disposed at the filter housing and formed with a space storing dust separated from the prefilter. The brush unit may be disposed between the roller and the dust tub. The dust bucket may constitute the filter assembly together with the brush unit.
In this case, the user or operator may wash the prefilter with a washing solution such as water by pulling the filter assembly out of the air conditioner, may replace the brush unit or remove foreign substances remaining in the brush unit, and may empty the dust tub.
The filter housing may include an upper cover formed with the outer inlet and a lower housing formed with the inner outlet, and a dust tub accommodating space accommodating the dust tub may be formed between the lower housing and the upper cover.
The brush unit may include: a brush body formed with a dust passage opening toward the roller; and a brush formed in a side of the brush body facing the roller and contacting a portion of the prefilter bent along the roller.
The air conditioner according to the present embodiment may include: a main body formed with a suction portion and a discharge portion; and a blower fan accommodated in the main body. The filter assembly may be configured to be capable of being pulled out from the main body to the outside, and a roller rotation mechanism may be installed in the main body, to which the roller is detachably connected.
The air conditioner may further include a filter cleaning device to which the dust bucket is detachably connected, the filter cleaning device being mountable to the main body, the dust bucket being connectable with the filter cleaning device when the filter assembly is mounted to the main body.
According to the embodiment of the present invention, the prefilter moves inside the filter housing along the outer circumference of the roller and is cleaned by the brush unit, so that it is not necessary to pull it out of the filter housing to the outside when cleaning the prefilter, and thus the space utilization inside the air conditioner is high.
In addition, the prefilter does not contact or interfere with other components located outside of the filter housing, thus minimizing contamination and damage of the prefilter or other components that may occur if the prefilter contacts or interferes with other components.
In addition, the roller, the prefilter, and the brush unit can be pulled out of the air conditioner to the outside together with the filter housing, and thus, a user or an operator can easily manage the roller, the prefilter, and the brush unit.
In addition, the electrostatic filter disposed inside the filter housing is spaced apart from the roller disposed inside the filter housing, so that damage to the electrostatic filter by the roller can be minimized.
In addition, the electrostatic filter can be pulled out of the air conditioner together with the roller, the prefilter, the brush unit, and the filter housing, and thus has an advantage of convenient maintenance and management as compared with a case where the roller, the prefilter, the electrostatic filter, and the brush unit are pulled out separately.
In addition, the portion of the prefilter that moves along the outer circumference of the roller may be guided between the electrostatic filter and the lower case by the guide body, so that the prefilter can be moved smoothly and stably to the maximum extent.
In addition, the portion of the prefilter located between the filter guide and the roller is guided and curved in an arc shape by the roller and the guide surface, respectively, and it is possible to minimize malfunction of the prefilter and stably move the prefilter.
In addition, a dust tub storing dust separated from the filter is provided at the filter housing, and a user or operator can wash the prefilter with a washing solution such as water by pulling the filter assembly out of the air conditioner, can replace the brush unit or remove foreign materials remaining in the brush unit, and can empty the dust tub.
In addition, the filter assembly may be configured to be capable of being pulled out from the main body to the outside, and a roller rotation mechanism to which the roller is detachably connected is installed in the main body. Thus, a user or operator can easily wash the entire filter assembly separated from the roller rotation mechanism with a washing solution such as water.

The high voltage power supply 180 may apply a high voltage to the filter assembly 300 and a charging module 360 (refer to fig. 9) described later. The charging module 360 may ionize foreign matters such as dust in the air, and the foreign matters ionized by the charging module 360 may be collected inside the filter assembly 300.
The filter assembly 300 may include a filter housing 310 and at least one filter housed inside the filter housing 310. The Filter assembly 300 may include a prefilter 340 (Pre Filter, see fig. 3) housed inside the Filter housing 310.
The pre-filter 340 may be a filter for filtering foreign matters flowing into the air conditioner, and in particular, for filtering foreign matters flowing into the inside of the filter assembly 300. The pre-filter 340 may have a mesh shape. The pre-filter 340 may be located before an air conditioning unit (e.g., heat exchanger 60) in the air flow direction.
The filter assembly 300 may include a plurality of filters, in which case the filter assembly 300 may further include a dust collecting filter 350 (refer to fig. 4).
When the filter assembly 300 includes the pre-filter 340 and the dust collecting filter 350, the pre-filter 340 may be located before the dust collecting filter 350 in the air flow direction.
An example of the dust collecting filter 350 may be a high performance filter, such as a high efficiency air filter (High efficiency particulate air Filter) capable of filtering out fine dust or the like.
Another example of the dust collecting filter 350 may be an electrostatic dust collecting filter that collects dust by using electricity. In a state where the dust collecting filter 350 is accommodated inside the filter housing 310, the dust collecting filter 350 may be electrically connected to the high voltage power supply 180 through a wire, a terminal, or the like. The dust collecting filter 350 may be an electrostatic filter that collects foreign matters using static electricity of the foreign matters ionized by the charging module 360.
Hereinafter, the dust collecting filter 350 is described as an example of an electrostatic filter, and the same reference numerals as those of the dust collecting filter 350 will be used to describe the electrostatic filter. However, the present invention is not limited to the dust collecting filter 350 being an electrostatic filter.
The pre-filter 340 may filter out larger dust in the air flowing toward the electrostatic filter 350 in a state of being located at an upper side of the electrostatic filter 350.
The electrostatic filter 350 may be disposed between the pre-filter 340 and the filter housing 310. The electrostatic filter 350 may be spaced apart from the roller 372. The thickness of the electrostatic filter 350 in the air flow direction may be less than or equal to the diameter of the roller 372.
The air conditioner may further include a brush unit 380 (refer to fig. 4), and the brush unit 380 may separate foreign substances (hereinafter, referred to as 'dust') such as dust, etc., attached to the filter from the filter (e.g., the pre-filter 340). In addition, the air conditioner may further include a dust tub 390 (refer to fig. 4), and dust separated from the filter is contained in the dust tub 390.
The brush unit 380 may be arranged in a position where it can contact the filter, in particular the pre-filter 340.
The dust attached to the pre-filter 340 may be separated from the pre-filter 340 by contacting with the brush unit 380, and the dust separated from the pre-filter 340 may flow into the dust bucket 390 to be stored inside the dust bucket 390.
The dust bucket 390 can be pulled out to the outside of the air conditioner, and dust stored inside thereof can be discarded by a user or the like.
The air conditioner may further include a filter cleaning device 400 (refer to fig. 2), and the filter cleaning device 400 serves to separate dust accumulated in the filter, particularly, the prefilter 340.
The filter cleaning device 400 may communicate with the dust bucket 390 when the dust bucket 390 is mounted in the air conditioner. The filter cleaning device 400 may be separated from the dust bucket 390 when the dust bucket 390 is pulled out to the outside. The filter cleaning device 400 may be a suction unit connected to the dust bucket 390 to suck air in the dust bucket 390. The filter cleaning device 400 may include a fan motor unit blowing by sucking air in the dust bucket 390. The filter cleaning device 400 may be a fan motor unit detachably contacting the dust bucket 390.
An electric wire may be connected to the filter cleaning device 400, and the filter cleaning device 400 may be mounted to the main body 10.
The filter cleaning device 400 may be accommodated between the housing 100 and the chassis 30. The filter cleaning device 400 may be disposed inside the housing 100. The filter cleaning device 400 may be configured to be located on an upper side of the control module 50.
When the filter cleaning device 400 is driven, the suction force of the filter cleaning device 400 may act on the filter (particularly, the pre-filter 340) through the dust bucket 390 and the brush unit 380, and dust attached to the filter of the filter assembly 300 may flow into the dust bucket 390 to be temporarily stored inside the dust bucket 390.
As shown in fig. 4, the brush unit 380 and the dust bucket 390 may be disposed at the filter housing 310, and may be drawn out to the outside of the air conditioner together with the filter housing 310.
In this case, the brush unit 380 and the dust bucket 390 may form part of the filter assembly 300, and the dust bucket 390 may be connected to or separated from a filter cleaning device 400 described later.
On the other hand, the brush unit 380 and the dust bucket 390 may be disposed at the chassis 30 or the housing 100, not at the filter housing 310. In this case, the brush unit 380 and the dust tub 300 may be maintained in a state of being connected to the filter cleaning device 400, and may be connected to the filter assembly 30 when the filter assembly 30 is installed.
The brush unit 380 and the dust bucket 390 are preferably configured to require washing by a user or service provider and are easily pulled out or installed.

Fig. 5 is a perspective view of the front panel shown in fig. 1 in the first position, fig. 6 is a perspective view of the front panel shown in fig. 1 in the second position, and fig. 7 is a perspective view of the front panel shown in fig. 1 in the third position.
As shown in fig. 5 to 7, the driving mechanism 170 (refer to fig. 2) may raise or lower the front panel 150. The driving mechanism 170 may be a front panel lifting mechanism for lifting the front panel 150.
As shown in fig. 7, the discharge portion formed in the housing 100 may further include a front discharge portion 129. The front discharge portion 129 may be formed by opening a part thereof in the front lower portion of the casing 100 in the front-rear direction.
The drive mechanism 170 may move the front panel 150 to a plurality of positions.
The plurality of positions may include a first position P1 and a second position P2.
The first position P1 may be a position where the front panel 150 covers the front 301 of the filter assembly 300.
The second position P2 may be a position relatively lower than the first position P1. The second position P1 may be a position where the front panel 150 exposes the front 301 of the filter assembly 300. The first position P1 and the second position P2 may be positions where the front panel 150 shields the front discharge port 129.
When the front panel 150 is in the first position, as shown in fig. 5, the front panel 150 may conceal the front face 301 and the front discharge port 129 of the filter assembly 300.
When the front panel 150 is in the second position, as shown in fig. 6, the front panel 150 may expose the front face 301 of the filter assembly 300 and conceal the front discharge opening 129.
When the front panel 150 is positioned at the second position, the upper end of the front panel 150 may be positioned at the front lower side of the filter assembly 300, and the filter assembly 300 may be movable forward beyond the upper end of the front panel 150.
When the front panel 150 is positioned at the second position P2, the user or the air conditioner may move the filter assembly 300 forward, and the user may easily pull out the filter assembly 300 forward without separating the front panel 150 or the housing 100.
The user can easily wash the filter assembly 300 pulled out from the front of the upper housing 114 using a washing solution such as water. The user may place and insert the filter assembly 300 into the upper housing 114 after washing the filter assembly 300, and the filter assembly 300 may be inserted and received into the upper housing 114.
On the other hand, the plurality of positions may further include a third position P3. The third position P3 may be a position relatively higher than the first position P1. As shown in fig. 7, the third position P3 may be a position where the front panel 150 opens the front discharge port 129, and may be a position where the front panel 150 covers the front face 301 of the filter assembly 300. When the front panel 150 is located at the third position, air flowing toward the filter assembly 300 may be guided to the rear surface of the front panel 150 and then sucked into the filter assembly 300.
The air conditioner may selectively perform a lower air flow mode that discharges air conditioned downward of the casing 100 through the lower discharge portion 126 (see fig. 1) and a front air flow mode that discharges air conditioned forward of the casing 100 through the front discharge portion 129 (see fig. 6).
When the front panel 150 is positioned at the first position P1 or the second position P2, the air conditioner may discharge the air conditioned by the lower discharge portion 126.
When the front panel 150 is positioned at the third position, the air conditioner can discharge the air conditioned by the front discharge portion 129 and the lower discharge portion 126.
Fig. 8 is a top view of an air conditioner according to an embodiment of the present invention, fig. 9 is a cross-sectional view taken along a line A-A 'of fig. 8, fig. 10 is a cross-sectional view taken along a line B-B' of fig. 8, fig. 11 is a bottom view showing an inside of a dielectric filter according to an embodiment of the present invention, and fig. 12 is a view showing a filter assembly and a moving mechanism according to an embodiment of the present invention.
The air conditioner may further include a charging module 360 (or an ionization module, refer to fig. 8 and 9).
The charging module 360 may be an electrolysis module or an ionization module that ionizes foreign substances in the air. The charging module 360 may be configured such that foreign substances in the air can be ionized before flowing into the electrostatic filter 350.
The charging module 360 ionizes foreign matters in the air flowing to the electrostatic filter 350, and may include a discharge electrode 361 that ionizes the foreign matters in the air when a high voltage is applied.
The discharge electrode 361 may include a fiber combination such as Carbon fiber or Carbon fiber. The discharge electrode 361 may be electrically connected to the high voltage power supply 180 shown in fig. 2.
The discharge electrode 361 may be built in the filter assembly 300 to adhere ionized foreign objects to the electrostatic filter 350. However, when the discharge electrode 361 is disposed inside the filter assembly 300, the filter assembly 300 may become thick due to the thickness of the discharge electrode 361, the distance between the discharge electrode 361 and the electrostatic filter 350, and the like. In addition, when the user separates the filter assembly 300 from the chassis 30 or the case 100 to clean the filter assembly 300, the discharge electrode 361 needs to be electrically disconnected from the high-voltage power source 180, and the possibility of damage of the discharge electrode 361 may be increased when the filter assembly 300 is washed.
The discharge electrode 361 is preferably located outside the filter assembly 300, and the discharge electrode 361 is preferably not pulled out together with the filter assembly 300 even if the filter assembly 300 is pulled out to wash the filter assembly 300.
The discharge electrode 361 may be located in the chassis 30 or the casing 100, and may be disposed to face the outside of the air conditioner, for example. In this case, the discharge electrode 361 may ionize foreign substances in the air outside the air conditioner, particularly outside the filter assembly 300.
Foreign substances in the air outside the air conditioner may be ionized outside the filter assembly 300, and the foreign substances ionized by the discharge electrode 361 may be sucked into the filter assembly 300 and collected by the electrostatic filter 350 through the filter assembly 300.
On the other hand, the discharge electrode 361 is preferably arranged to ionize as much as possible foreign matter in the air surrounding the filter assembly 300, and for this purpose, the discharge electrode 361 may be arranged close to the upper case 114, for example, toward the upper side of the upper case 114.
When the blower fan 40 is driven, external air of the air conditioner may flow to the upper side of the upper case 114 and the filter assembly 300 and then may be sucked into the filter assembly 300, so that foreign substances in the air flowing to the upper side of the upper case 114 and the filter assembly 300 are preferably ionized by the discharge electrode 361.
The discharge electrode 361 toward the upper side of the upper case 114 may minimize power loss of foreign substances in ionized air.
The charging module 360 may further include a module installer 364, and the module installer 364 is disposed at an upper portion of at least one of the chassis 30 and the housing 100.
The inside of the module mounter 364 may be formed with a space S5 accommodating the discharge electrode 361. Such a space S5 may be formed larger than the discharge electrode 361.
The discharge electrode 361 is preferably configured to have an upper end lower than an upper end of the module mounter 364. In this case, the discharge electrode 361 may be protected by the module installer 364, and it is possible to minimize a safety accident or damage of the discharge electrode 361 that may occur when a user touches the discharge electrode 361.
The module mounter 364 may have a wire through hole 365 formed therein, and the wire 362 connected to the discharge electrode 361 may pass through the wire through hole 365. Such an electric wire 362 may be fixed by being interposed in the electric wire through hole 365, and the electric wire 362 connected to the discharge electrode 361 may extend into the high-voltage power supply 180 shown in fig. 2.
On the other hand, a pair of the charging modules 360 may be provided in the air conditioner. A pair of charging modules 360A and 360B may be spaced apart in the length direction Y of the filter assembly 300.
The filter assembly 300 may have a polygonal shape having a length in the left-right direction Y longer than that in the front-rear direction X, and the length L2 of the filter assembly 300 may be defined as the length in the left-right direction Y of the filter assembly 300.
The distance L1 between the pair of charging modules 360A and 360B may be greater than or equal to the length L2 of the filter assembly.
The pair of charging modules 360A and 360B may be symmetrically configured across the filter assembly 300.
The pair of charging modules 360A and 360B may include a left charging module 360A located on the left side of the filter assembly 300 and a right charging module 360B located on the right side of the filter assembly 300.
Hereinafter, the same constitution in the left and right charging modules 360A and 360B will be referred to as a charging module 360, and when it is necessary to distinguish between the left and right charging modules 360A and 360B, it will be referred to as a left and right charging module 360A and 360B, respectively.
The distance L3 between the discharge electrode 361 of the left charging module 360A and the discharge electrode 361 of the right charging module 360B may be longer than the length L2 of the filter assembly 300.
The extension lines E1 and E2 respectively extending from the discharge electrodes 361 of the pair of charging modules 360A and 360B may cross each other outside the air conditioner. Such extension lines E1 and E2 may cross each other at the upper side of the filter assembly 300.
When the blower fan 40 rotates, foreign matters in the air flowing toward the upper side of the filter assembly 300 may be ionized when passing around the discharge electrode 361, and the foreign matters ionized by the discharge electrode 361 may be adsorbed and collected by the electrostatic filter 350 from the foreign matters passing through the prefilter 340.
Hereinafter, the filter assembly 300 is described in detail.
The inside of the filter housing 310 may be formed with a space S3 accommodating at least one filter.

The upper cover 320 may be an outer cover capable of forming the appearance of the top surface of the air conditioner when the filter assembly 300 is mounted to the air conditioner.
When the filter assembly 300 is mounted to the air conditioner, the lower case 330 may be an inner case whose bottom surface can face the inside of the air conditioner, particularly, the inner space S1.
The pre-filter 340 may be formed of a flexible material that can be bent or curved. The length of the pre-filter 340 in the left-right direction may be longer than the length of the pre-filter 340 in the front-rear direction.
As shown in fig. 10, the pre-filter 340 may include a filter net 342, and the filter net 342 is formed with a through hole through which air can pass. The pre-filter 340 may include a filter body 344 supporting a filter mesh 342.
The pre-filter 340 may be accommodated between the electrostatic filter 350 and the upper cover 320.
The electrostatic filter 350 may be a trapping module that traps foreign matters ionized by the charging module 360. The electrostatic filter 350 may be accommodated in such a manner as to be located behind the prefilter 340 in the direction of air flow.

As shown in fig. 11, the first filter body 351 and the second filter body 352 may be arranged to be spaced apart in a direction X orthogonal to the air suction direction Z. The first filter body 351 and the second filter body 352 may be alternately disposed in a direction X orthogonal to the air suction direction Z.
Electrode terminals may be disposed in the electrostatic filter 350. A pair of electrode terminals may be provided in the electrostatic filter 350, and as shown in fig. 11, the pair of electrode terminals may be an anode terminal 353 and a ground terminal 354.

The anode terminal 353 and the ground terminal 354 may each be configured to penetrate the filter frame of the electrostatic filter 350, and a portion thereof may be located outside the filter frame of the electrostatic filter 350.
The ground terminal 354 may be electrically connected with the second electrode 352A and may be spaced apart from the first filter body 351.
A portion of the second electrode 352A in the second filter body 352 may be in contact with the ground terminal 354.

The rack 530 may be formed long in the front-rear direction at the lower portion of the lower case 330.
The movement mechanism 500 may be controlled by the control module 50. When the control module 50 controls the motor 510 in the forward mode, the motor 510 may rotate the rotation shaft in any one of the clockwise direction and the counterclockwise direction, thereby enabling the rack 530 to be advanced, and the filter assembly 300 may be advanced in the forward direction in a state of being placed on the upper housing 114.
When a user inputs a command to pull out the filter assembly 300 through an input part such as a remote controller or the like, or the air conditioner is in a condition to pull out the filter assembly, the control module 50 may transmit a signal of a forward mode to the motor 510.
As an example of the condition for pulling out the filter unit, the air conditioner may be operated for a set time.
