The first assembly (100) can be positioned upstream of the second assembly (200). For example, when the exhaust port (13b) is positioned above the intake port (13a) and the blower fan (30) moves the air upward, the second assembly (200) can be arranged above the first assembly (100).

[0087] The first assembly (100) and the second assembly (200) are detachably coupled. The first assembly (100) and the second assembly (200) may be arranged to be mutually assembleable. For example, the second assembly (200) may be arranged to be mounted on the first assembly (100). For example, the upper portion (150) of the first assembly (100) and the lower portion (250) of the second assembly (200) may be arranged to face each other.

[0088] Typically, an electrostatic precipitator may include a charging unit and a dust collector. However, separating the charging unit and dust collector requires the entire electrostatic precipitator case to be disassembled. Alternatively, a separate rail structure may be required for the electrostatic precipitator case. Consequently, maintenance of the electrostatic precipitator can be difficult and its usability may be reduced.

[0089] In contrast, according to the present disclosure, the first assembly (100) and the second assembly (200) are detachably coupled. The first assembly (100) and the second assembly (200) can each perform the functions of charging an aerosol in the air and capturing the charged aerosol. That is, in order to separate the first assembly (100) and the second assembly (200), the entire electrostatic precipitator (50) does not need to be disassembled, and a separate rail structure is not required. Meanwhile, the first assembly (100) does not need to be washed with water because it does not capture an aerosol in the air. In addition, as will be described later, the first assembly (100) may not be washed with water because it includes a discharge electrode (120) and a substrate (121). The second assembly (200) needs periodic washing management because it captures an aerosol in the air. In addition, as will be described later, the second assembly (200) includes a dust collecting electrode (220) and needs to be washed with water to remove dust, etc. collected on the dust collecting electrode (220). That is, different maintenance is required according to the functions of each of the first assembly (100) and the second assembly (200). Since the first assembly (100) and the second assembly (200) are separable, maintenance of each of the first assembly (100) and the second assembly (200) can be easily performed. For example, the first assembly (100) can be managed by shaking off dust accumulated on the discharge electrode (120) and / or the substrate (121). For example, the second assembly (200) can be managed by washing dust collected on the dust collecting electrode (220) with water. As a result, maintenance of the electric dust collector (50) can be easy and usability can be improved.

[0090] Referring to FIG. 8, the first assembly (100) may include a discharge electrode (120). The discharge electrode (120) may emit electrons when a voltage is applied.

[0103] The first assembly (100) may include a first inclined portion (160) formed on the edge of the upper portion (150). The first inclined portion (160) may be arranged to surround the upper portion (150). For example, the first inclined portion (160) may have a closed loop shape. For example, the first inclined portion (160) may have an approximately square ring shape. For example, the first inclined portion (160) may have a shape that slopes upward toward the outside.

[0104] The first assembly (100) may include an inlet (51) through which air is introduced. The inlet (51) may be arranged to face the suction port (13a) (see FIG. 2). Air passing through the suction port (13a) may flow into the electrostatic precipitator (50) through the inlet (51). The inlet (51) may be formed to penetrate the first case (110) of the first assembly (100).

[0111] An electric field may be formed between the first dust collecting electrode unit (221) and the second dust collecting electrode unit (222), and the aerosol charged in the first assembly (100) may be captured by the dust collecting electrode (220). While the air passes between the first dust collecting electrode unit (221) and the second dust collecting electrode unit (222), pollutants contained in the air may be adsorbed on the dust collecting electrode (220). For example, a high voltage may be applied to the first dust collecting electrode unit (221), and the second dust collecting electrode unit (222) may be grounded.

However, the present disclosure is not limited thereto, and at least some of the fourth frame part (211), the fifth frame part (212), and the sixth frame part (213) may be formed integrally. The second case (210) may also be provided as a single configuration.

[0119] The fourth frame portion (211) can support a ground electrode (230). The ground electrode (230) can be mounted on the inside of the fourth frame portion (211).

[0120] The fifth frame part (212) may be provided to support the dust collecting electrode (220). The fifth frame part (212) may be provided to cover a portion of the front part and a portion of the rear part of the dust collecting electrode (220).

[0124] The second inclined portion (260) may be provided to correspond to the first inclined portion (160) (see FIGS. 17 and 18). As the second assembly (200) is coupled to the first assembly (100), the second inclined portion (260) may contact the first inclined portion (160). As the second assembly (200) is coupled to the first assembly (100), the second inclined portion (260) may be seated on the first inclined portion (160). For example, the inclination angle of the second inclined portion (260) may be the same as the inclination angle of the first inclined portion (160). As the first inclined portion (160) and the second inclined portion (260) correspond, air leakage between the first assembly (100) and the second assembly (200) may be reduced and / or prevented. Air passing through the first assembly (100) can flow to the second assembly (200) without being discharged outside the electrostatic precipitator (50).

[0125] The second assembly (200) may include an outlet (52) through which air flows out. Air passing through the dust collecting electrode (220) may flow out of the electrostatic precipitator (50) through the outlet (52).

For example, the receiving groove (2402) may be recessed upward.

[0128] The second grip section (240) may be referred to as a second handle (240).

[0129] A detailed description of the second phasing section (240) will be provided later.

[0130] Fig. 12 illustrates a state in which some components are separated in an air conditioner according to one embodiment. Fig. 13 illustrates a state in which some components are separated in an air conditioner according to one embodiment. Fig. 14 is an enlarged view of a part of a state in which some components are separated in an air conditioner according to one embodiment.

[0131] Referring to FIGS. 12 and 13, the main body (10) of the air conditioner (1) may include a housing (101) and a front panel (11a).

[0132] The housing (101) may include an opening (102). The opening (102) may be formed by opening the front of the housing (101). The housing (101) may have a substantially box-like shape with the front open. The housing (101) may form an internal space for accommodating components of the air conditioner (1).

[0133] For example, the housing (101) may include a portion of the main body (10) excluding the front panel (11a). For example, the housing (101) may include an upper panel (15), a support (16), a right panel (11c), a left panel (11d), and a rear panel (11b).

[0134] The front panel (11a) may be provided to cover the opening (102). The front panel (11a) may be provided to cover components arranged inside the main body (10). The front panel (11a) may be provided to cover components accommodated in the housing (101). The front panel (11a) may form at least a portion of the front surface of the main body (10).

[0135] The front panel (11a) can be detachably connected to the housing (101).

[0136] While the front panel (11a) is separated from the housing (101), the electrostatic precipitator (50) housed inside the main body (10) can be exposed through the opening (102). While the front panel (11a) is separated from the housing (101), the electrostatic precipitator (50) can be made accessible through the opening (102).

[0137] While the front panel (11a) is separated from the housing (101), the first grip portion (140) can be exposed through the opening (102). While the front panel (11a) is separated from the housing (101), the first grip portion (140) can be provided to be accessible through the opening (102). While the first assembly (100) is housed within the main body (10), the first grip portion (140) can be positioned to face the opening (102). This allows a user to easily access the first grip portion (140) exposed through the opening (102) after separating the front panel (11a) from the housing (101).

[0138] While the front panel (11a) is separated from the housing (101), the second grip portion (240) can be exposed through the opening (102). While the front panel (11a) is separated from the housing (101), the second grip portion (240) can be provided to be accessible through the opening (102). While the second assembly (200) is housed within the main body (10), the second grip portion (240) can be positioned to face the opening (102). This allows a user to easily access the second grip portion (240) exposed through the opening (102) after separating the front panel (11a) from the housing (101).

[0139] The electric dust collector (50) can be detachably mounted on the main body (10). The electric dust collector (50) can be accommodated inside the main body (10) or detached from the main body (10) while moving approximately in the forward-backward direction (X direction).

[0140] The electrostatic precipitator (50) may be arranged to be withdrawn from and inserted into the housing (101) through the opening (102). While the front panel (11a) is separated from the housing (101), the electrostatic precipitator (50) may be arranged to be withdrawn from and inserted into the housing (101) while the first assembly (100) and the second assembly (200) are coupled. That is, the first assembly (100) and the second assembly (200) may be withdrawn from the housing (101) at one time. The first assembly (100) and the second assembly (200) may be inserted into the housing (101) at one time. For example, a user may separate the electrostatic precipitator (50) with the first assembly (100) and the second assembly (200) coupled from the housing (101) or couple it to the housing (101). At this time, the user can grip the first grip part (140) and the second grip part (240) together. While the electric dust collector (50) is mounted on or separated from the main body (10), the first assembly (100) and the second assembly (200) may not be separated from each other. This prevents at least one of the first assembly (100) and the second assembly (200) from falling to the floor and being damaged. Consequently, the risk of damage to the electric dust collector (50) can be reduced.

[0141] Referring to FIG. 14, the electric precipitator (50) may include a locking member (300). The locking member (300) may secure the electric precipitator (50) to the main body (10). The locking member (300) may prevent the electric precipitator (50) accommodated inside the main body (10) from being overturned. Although each electric precipitator (50) is illustrated in the drawing as including two locking members (300), the present disclosure is not limited thereto.

The operating portion (320) is movable along the horizontal direction (Y direction). For example, a user may adjust the protrusion degree of the locking protrusion (310) described below by moving the operating portion (320).

[0143] The locking member (300) may include a locking protrusion (310). The locking protrusion (310) may protrude from the first case (110) and / or the second case (210). For example, a protrusion hole (280) may be formed in the second case (210), and the locking protrusion (310) may protrude through the protrusion hole (280) (see FIGS. 5 and 6).

[0144] The locking protrusion (310) can move in conjunction with the operating unit (320). The locking protrusion (310) can move integrally with the operating unit (320). The locking protrusion (310) can move in a direction crossing the air flow direction together with the operating unit (320). The locking protrusion (310) is movable along the horizontal direction (Y direction). The locking protrusion (310) can be arranged to be caught on the inside of the main body (10). The locking protrusion (310) can be arranged to be fixed on the inside of the main body (10).

[0145] The main body (10) may include a catch (103). The catch (103) may be provided to correspond to a locking projection (310). While the electric dust collector (50) is placed inside the main body (10) and the locking projection (310) protrudes, the catch (103) may be provided to interfere with the locking projection (310). The catch (103) may be provided to contact the locking projection (310). The catch (103) may be formed on an inner wall of the main body (10). The catch (103) may be formed on an inner wall of the housing (101). For example, the catch (103) may include a step.

[0146] Fig. 15 illustrates an example of a process for joining a first assembly and a second assembly according to one embodiment. Fig. 16 illustrates an example of a process for joining a first assembly and a second assembly according to one embodiment.
