As shown in the present embodiment, the first and second intermediate portions described below can be provided on the rail portion 414a of the sliding portion 414, but in other embodiments, the rail portion 147a provided on the drawer guide portion 147 can also perform the same function. The present embodiment will be described below, and the above embodiment also describes another embodiment in which the first section and the second section are provided in the rail portion 147a of the drawer guide portion 147.
Referring to fig. 22 and 23, the rail portion 414a includes a first section 414a1, and when the drawer 400 starts to be introduced into the internal space of the filter housing 140, the first section 414a1 forms a flat surface from a first position p1 in contact with the roller 147b to a predetermined position p 2. The rail portion 414a includes a first section 414a1, and the first section 414a1 forms a flat surface from a predetermined position p1 to a second position p2 where the first section 414a1 contacts the roller 147b before the front end 400a1 of the drawer opening 400a is drawn into the internal space of the filter housing 140 from the predetermined position p 1. The rail portion 414a includes a first section 414a1, and when the drawer 400 starts to be introduced into the inner space of the filter housing 140, the first section 414a1 forms a flat surface from a first position p1 contacting the roller 147b to a second position p2 contacting the roller 147b before the front end 400a1 of the drawer opening 400a is introduced into the inner space of the filter housing 140.

In the introduction and extraction of the electric dust collector 500, the abrasion phenomenon due to friction is reduced by preventing the contact of the terminals which do not correspond to each other, and the application of unnecessary power is prevented. In particular, even if the drawer 400 is not in the state of the inner space of the filter housing 140 during the drawing out of the electric dust collector apparatus 500, if the terminals are in contact and power is applied, there may be a danger of electric shock to the human operator, and the present invention may take place in such a manner.
Referring to fig. 24 to 27, the filter housing 140 includes a cut-off switch 145 for determining whether the electric dust collector apparatus 500 is operable. The cut-off switch 145 may be disposed at the filter housing 140. The cut-off switch 145 controls whether or not power is supplied to the high voltage generator 581. In the case where the cut-off switch 145 is pressed, the power of the high voltage generator 581 may be applied. The cutoff switch 145 can control whether other power is supplied to the electrostatic precipitator 500 to desired components (e.g., sensors, displays, motors, etc.).
The cut-off switch 145 allows the air cleaning apparatus 100 to be operated even in a state where the electric dust collector apparatus 500 and the drawer 400 are seated in the filter housing 140. When the electric dust collector apparatus 500 and the drawer are separated from the filter housing 140, the cut-off switch 145 does not operate the air cleaning apparatus 100. The cut-off switch 145 does not operate the air cleaning apparatus 100 in a state where the electric dust collector apparatus 500 and the drawer 400 are not completely coupled (seated) to the filter housing 140.
The cut-off switch 145 is disposed on the supply line 585. The cut-off switch 145 controls whether or not power is applied to the high- voltage generators 581a, 581b.

In a state where the filter assembly 10 is in the inner space of the filter housing 140, the cut-off protrusion 144 presses the cut-off switch 145. When the cutoff protrusion 144 presses the cutoff switch 145, the power supply line 585 opened by the cutoff switch 145 is in a short-circuited state, and power can be applied to the high-voltage generator 581. Accordingly, in a state where the filter assembly is separated from the filter housing 140, when a user comes into contact with the power terminals 148a and 148b and the ground terminals 149a and 149b, the filter assembly is prevented from being electrically shocked. The electric dust collector apparatus 500 may include a cut-off protrusion 144.

In a state where the drawer 400 is separated from the inner space of the filter housing 140, the high potential electrode 541 and the low potential electrode 542 are short-circuited with each other, and thus the charged charges are removed from the dust collecting part 540. When the pressing is released, the short-circuit switch 600 causes the high-potential electrode 541 and the low-potential electrode 542 to be in a short-circuit state.
When the drawer 400 is in the internal space of the filter housing 140, the short circuit between the high potential electrode 541 and the low potential electrode 542 is released, and the electric charges in the dust collection unit 540 are charged to generate an electromagnetic field.

The short-circuiting switch 600 may include an elastic body disposed on the opposite side of the pressing surface of the pressing portion 626. When the pressing portion 626 is pressed, the elastic body is elastically compressed, and when the pressing of the pressing portion 626 is released, the elastic body is restored.
There may be a plurality of shorting switches 600. The electric dust collector 500 may include a plurality of short-circuit switches.
The short-circuiting switches 600 are connected in parallel to the short- circuiting lines 600a, 600b. Even if at least one of the plurality of short switches 600-1, 600-2 is in a short-circuited state, the high potential electrode 541 and the low potential electrode 542 are short-circuited to each other. Accordingly, even if one of the short-circuit switches 600 fails to operate normally due to the presence of a foreign object or a fault, if at least another one of the short-circuit switches operates normally, the high-potential electrode 541 and the low-potential electrode 542 are short-circuited with each other, thereby further enhancing safety of users.
In the present embodiment, the electric dust collector 500 includes two short-circuiting switches 600-1, 600-2. The two shorting switches 600-1, 600-2 may be arranged laterally apart. The electric dust collector 500 may include a first short switch 600-1 and a second short switch 600-2.
