The air purifier main bodies 102, 102 arranged in this way have a cover 103 for closing the mounting port 104 in a frame body (not shown) of the cooling unit 100. It is fixed there by screwing. Therefore, when cleaning the air purifier body 102 or replacing the service, it is necessary to remove the cover 103 and remove the air purifier body 102 from the cooling unit 100.

[0003]

By the way, in this type of air cleaner, a high voltage is applied between the wire electrode and the plate electrode provided inside the air cleaner body 102 so as to face each other. The corona discharge generated thereby charges the dust passing between these electrodes, and the electrostatic absorption force of this charging is used to remove the dust. As described above, since a high voltage is supplied to the air purifier body 102, it is necessary as a safety measure that the high-voltage power supply is always turned off when the air purifier body 102 is removed from the cooling unit 100.

Therefore, in the conventional air-conditioning unit of this type, for example, a limit switch is provided on the cooling unit 100 side, and the limit switch is operated by removing the air purifier main body 102 from the cooling unit 100, The high voltage supplied to the air purifier body 102 is automatically cut off. However, in this type of conventional air conditioning unit, it is necessary to install a limit switch, which increases the cost, and reliability of the voltage supply to the air purifier body 102 due to poor connection of the limit switch. There is a problem that accidents that impair the property are likely to occur.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide an improved air conditioning unit with an air cleaner, which is able to solve the above mentioned problems in the prior art.

[0006]

The features of the present invention for solving the above-mentioned problems are that a heat exchanger, an attachment / detachment port formed on an upstream side surface of the heat exchanger, and an insertion / removal port are inserted. An air conditioning unit comprising at least one air cleaner main body that covers the front surface of the heat exchanger and a cover that closes the attachment / detachment port, wherein a power supply terminal is provided on the cover side surface of the air conditioner cleaner main body, and The cover is provided with an opening for projecting the power supply terminal to the outside, and a coupler for supplying a required high-voltage power to the power supply terminal projecting to the outside through the opening is coupled to the power supply terminal. The high voltage is applied to the cover and the cover cannot be removed from the attachment / detachment port at the same time.

Therefore, when the air conditioning unit is operably assembled, the required high-voltage power supply is connected to the main body of the air washer through the coupler connected to the power supply terminal looking out from the opening of the cover. Is being supplied. At the same time, the coupler holds the cover so as not to come off from the attachment / detachment port. That is, the cover physically coupled to the power terminal protruding from the opening of the cover prevents the cover from being removed.

In order to remove the air purifier body from the attachment / detachment port, first the coupler must be removed from the power supply terminal and then the cover must be removed. Therefore, when removing the air purifier from the attachment / detachment port, the supply of high-voltage power to the air purifier is always stopped, and workers may get an electric shock accident due to high voltage during maintenance and inspection of the air purifier. Certainly avoided.

Here, the relationship between the cover and the coupler may be such that the coupler prevents the power terminal from being removed from the opening of the cover unless the coupler is disconnected from the power terminal. It may be fixed to the case or the frame side by screwing, or the cover may be fixed only by coupling the coupler to the power supply terminal.
