The effect of the electrostatic precipitating filter of the air conditioner according to the present invention configured as described above is as follows.

The blower fan 14 operates to suck air into the harmonic space through the suction unit 11, and discharge the air into the harmonic space through the discharge unit 12 through the indoor heat exchanger 18, and blower fan 14. The air circulated by force is heat-exchanged when it comes into contact with the indoor heat exchanger 18 to become conditioned air, and is discharged through the discharge part 12 to the conditioned space to harmonize the conditioned space.

At this time, dust or fine suspended matter contained in the air sucked through the suction unit 11 is collected by the electrostatic precipitator 20 installed in the suction unit 11, which will be described below.

First, in the state in which the suction grille 16 is closed, the safety switch 40 applies the power of the high pressure generator 30 to supply power to the high pressure generator 30. The high-voltage generator 30, which is supplied with power, boosts the input voltage to a high voltage and supplies a high voltage (about 3 Kv) to the electrostatic precipitating filter 21 through the second terminals 71 and 72 and the first terminal (not shown). The low pressure (0v) is applied at the same time. The electrostatic precipitating filter 21, which has been subjected to a high pressure and a low pressure, is to increase impurities such as dust by using corona discharge due to a voltage difference.

At this time, the leaf spring 90 supports the electrostatic precipitator 20 toward the second terminals 71 and 72 to secure the connection between the first terminal (not shown) and the second terminals 71 and 72. Sparks due to poor connection between the will be prevented.

In addition, the risk of electric shock by the high-pressure generator 30, which may be generated when the suction grill 16 is opened, is prevented by the safety switch 40 of the suction grill 16. When the suction grill 16 is opened, the lever 43 The lever intermittent portion 16 ', which has been pressed, is also rotated together, and the lever 43 rises to change the contact point of the safety switch 40 to cut off the power applied to the high pressure generator 30 to eliminate the risk of electric shock. .

As described in detail above, the electrostatic precipitating filter of the air conditioner according to the present invention solves the complexity in the installing part by installing a high-pressure generator that generates a high voltage supplied to the electrostatic precipitating filter on one side of the indoor heat exchanger instead of the installing unit. In addition, by shortening the supply line of the power supply (high pressure and low pressure), there is an advantage of reducing defects such as ease of manufacture and disconnection.

In addition, there is an advantage of eliminating the risk of electric shock generated when the suction grill is opened to clean the suction unit by controlling the power applied to the high pressure generator according to the opening and closing of the suction grill.

In addition, by installing a leaf spring to support the contacts of the first terminal and the second terminal has the advantage of preventing sparks due to contact failure.
