is installed.

The configuration of the adjustment mechanism 119 will be explained based on FIG. 8.9. The adjustment knob 118 is slidably supported in a slit 117 of a support plate 120 fixed to the inner surface of the upper end of the main body cover 4.

An arm 122 is rotatably supported at the center of the support plate 120 by a screw 121, and has a long hole 13 at its upper end.
An adjustment knob 118 is fitted and connected to the arm 122, and a connecting portion 123 is cut out at the lower end of the arm 122. Also, a pair of bins 1 are provided at the lower bent portion of the support plate 120.

is rotated between the solid line position and the chain line position shown in FIG.
10 is closed, and the lever 12 is closed.
The discharge port 114 is opened at the position indicated by the chain line 9. Therefore, by appropriately operating the adjustment knob 118, the opening of the discharge port 114 can be adjusted to adjust the amount of volatilization of the odor decomposing member 115. In addition, in FIGS. 3 and 8, reference numeral 107 denotes a presser projection protruding from the inner surface of the upper end of the side wall plates 39 and 40 of the support frame 36, and these prevent the deodorizing unit 108 in the attached state from lifting up. It looks like this.

Next, the operation of the electrical industry mi configured as above will be explained. Now, in FIG. 3, the dust collection unit 38 is housed in the support frame 36, and the deodorizing unit 108 is mounted above the dust collection unit 38, and the support frame 36 is
This figure shows a state in which the main body frame 1 accommodates and supports the main body frame 1. At this time, the high-voltage contact plate 75 of the support frame 36 is in contact with the high-voltage contact spring 27 of the power supply unit 21, and the ground contact plate 85 of the support frame 36 is in contact with the ground contact spring 28 of the power supply unit 21.

If you turn on the power switch 17 in this state,
When the fan 20 is started, a negative DC high voltage is applied from the DC high voltage generating section of the power supply unit 21 to the charging wire 66 of the support frame 36 and each negative electrode plate 95 of the dust collection unit 38 . Particles in the airflow introduced into the main body frame 1 from the suction grille 14 as the fan 20 rotates are negatively charged between the charged wire 66 and the lower end of the long positive electrode plate 93, and then Charged particles are transported between each of the positive and negative polar plates 93 to 95 by the air flow.

Thereupon, the charged particles in the airflow are attracted and captured on both sides of each positive electrode plate 93, 94 while being repulsed by each negative electrode plate 95.

Next, the air after dust collection in the dust collection unit 38 is sent to the deodorization unit 108 as the fan 20 rotates, and the odor is removed by the deodorization filter 113 in the deodorization case 109, and the odor decomposition case 110 The odor is decomposed by the odor decomposing member 115 in the
The fragrance from 4 is mixed into the air stream. Therefore, dust and odor are removed from the blow-off grill 15, and clean air containing fragrance is discharged into the room.

By the way, when a large amount of dust adheres to each of the positive electrode plates 93 and 94 in the dust collection unit 38 due to long-term use, these are replaced or cleaned as follows. First, as shown by the chain line in FIG. The main body cover 4 is held open. Next, as shown in FIG. 3, if the lower end of the support frame 36 is removed from the support piece 35 forward and the support frame 36 is slid downward along the rail portion 33,
The fitting between the rail portion 33 and the locking projection 44 is released, and the support frame 36 can be easily taken out from the main body frame 1. Then, the deodorizing unit 108 is removed together with the receiving frame 111 from the support frame 36. Next, support frame 3
Remove the terminal plate 68 from the right side wall plate 40 of No. 6 and pull out the dust collection unit 38 upward. In this case, each electrode plate 93 to 9
5 are integrally assembled and held via the connecting member 106, so unlike the conventional case where a plurality of electrode plates were taken out one by one, the work of taking out the dust collection unit 38 is extremely easy. be able to.

If each of the positive electrode plates 93 and 94 in the dust collection unit 38 is heavily contaminated, the entire unit 38 is replaced with a new one. In this case, since each of the electrode plates 93 to 95 is made of cardboard at low cost, they can be made into disposable parts and the troublesome cleaning work can be saved. Of course, if each of the positive electrode plates 93 and 94 is slightly contaminated, the unit 38 is cleaned with the unit 38 still assembled. At this time, since the entire area around the unit 92 is open, the cleaning operation can be easily performed.

Subsequently, the replaced or cleaned dust collection unit 38 is housed in the support frame 36 in the reverse order as described above, and the terminal plate 68 is
The accommodated state is reliably maintained by each gripping piece 79,87. Thereafter, the deodorizing unit 108 is attached to the upper part of the support frame 36.

In this way, the support frame 36 in which the dust collecting unit 38 and the deodorizing unit 108 are housed is again accommodated and supported within the main body frame 1, and the electrostatic precipitator is restarted.

Note that when the support frame 36 is taken out, the deodorizing filter 113 and the odor decomposing member 1 in the deodorizing unit 108 are removed.
Check the clogging and volatilization performance of No. 15, and if sufficient effect is not obtained, replace with a new one. Further, the amount of fragrance released from the odor decomposition case 110 is adjusted using the adjustment knob 11.
It can be easily adjusted even during operation by external operation of 8.

Furthermore, according to the configuration of the dust collection unit 38 described above, since each of the electrode plates 93 to 95 is assembled only by the connecting rod 100 and the spacing rod 102, each of the electrode plates 93 to 95 can be equally assembled with a small number of parts. Can be assembled accurately and easily in spaced positions. Moreover, when replacing the dust collection unit 38, the safety switch 34 is turned off and the electric circuit of the power supply unit 21 is opened when the main body cover 4 is opened.
It is possible to prevent electric shock accidents for workers caused by high DC voltage.

Effects of the Invention As described in detail above, according to the present invention, the dust collection unit is constructed from a plurality of positive and negative polar plates arranged alternately along the air flow, and each polar plate is spaced apart from each other. Since they are integrally assembled and held through the connecting member so as to be equal, the excellent effect is achieved that the removal and installation of each electrode plate during replacement or cleaning can be performed extremely easily.
