BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described in detail as examples based on the drawings. FIG. 1 is a cross-sectional view of an air conditioner according to the present invention. FIG. 1A shows a state in which an air suction grill is closed, and FIG. 1B shows a state in which an air suction grill is rotated to open an air suction port. There is.

The air conditioner according to the present invention includes, as an example, as shown in FIGS. 1 (A) and 1 (B), a base 1 fixed to a wall surface in a room through a predetermined fixing means, and a rear end portion. A front panel 2 having a cross-sectional bottom shape so that the front end portion is locked to the lower end portion of the base 1 and the front end portion is curved upward, and the rear end portion is locked to the upper end portion of the base 1 and the front end portion is Is provided with a main body cabinet including a front end of the front panel 2 and a top panel 3 that is butted.

A cross flow fan 4 is provided on the base 1.
And a dew receiver 7 formed in an inverted V shape are provided, an air outlet 8 is provided at the rear end side of the front panel 2, and a filter 10 is provided on the upper panel 3. The air suction grill 9 that it has is rotatably and detachably provided, and an electric air cleaner 11 is provided between the air suction grill 9 and the heat exchanger 6.

As shown in FIGS. 1A and 2, the electric air cleaner 11 has a plurality of "+ charge portions 11a" made of a conductive plate material and a conductive material made of, for example, a tungsten wire. And a plurality of "-charge portions 11b" each having an electric charge. By discharging between the + charge portion 11a and the-charge portion 11b, fine dust is attached to the-charge portion 11b. ing.

When the air suction grill 9 is removed during maintenance of the filter 10 and the electric air cleaner 11, electricity is supplied without increasing the number of constituent parts or complicating workability of assembly. In order to ensure safety by eliminating the risk of fingers touching the electric air cleaner 11, the electric air cleaner 11 is
The filter 10 is attached to the back surface of the suction bar 9a that constitutes the air suction grill 9, and a part of the filter 10 is made of a conductive dust collecting portion 10a. A structure is provided in which a current-carrying portion 12 is provided that is intermittently powered by coming into contact with or separating from the portion 10a.

Alternatively, the air conditioner according to the present invention, as another example, as shown in the sectional view of FIG. 2, has a base 1 fixed to a wall surface in a room through a predetermined fixing means, and the base 1
A front panel 2 ′ mounted on the front surface of the front panel and having an air inlet on the upper and upper surfaces of the front and an air outlet 8 on the lower side, and rotatably to an air inlet on the upper front of the front panel 2 ′, and The detachable air suction grill 9 is provided in an air passage connecting the air suction port and the air outlet 8.
The filter 10 having the dust collecting portion 10a having conductivity, the heat exchanger 6 having the dew receiver 7 at the bottom, the blower fan 4, and the air suction grill 9 are attached to the rear surface of the dust collecting portion 10a. 10a
The electric air cleaner 11 is provided with an energizing portion 12 which is energized intermittently by being brought into and out of contact with.

With the above configuration, the operation will be described below. When the filter 10 is removed for cleaning or the electric air cleaner 11 is maintained, the air suction grill 9 is rotated to rotate the air suction grill 9 so that the electric air purifier is installed. The current-carrying portion provided on the front end of the machine 11 and the filter 10 corresponding thereto.
When 12 is separated, the electric power to the electric air cleaner 11 is turned off.

As a result, even when a finger is inserted through the air suction opening opened by rotating the air suction grill 9, the electric power to the electric air cleaner 11 is turned off. Therefore, the safety can be secured.

Further, it becomes possible to easily remove the filter 10 from the opened air suction port and wash it.

Further, after the rotating air suction grill 9 is removed, the electric air cleaner 11 can be removed from the air suction grill 9 for maintenance of the electric air cleaner 11. Work can be done easily.

The dust collector 10a may be formed integrally with the filter 10 as shown in FIG. 2, or as shown in FIGS. 1 (B) and 1 (C). As shown in, it may be configured to be individually formed and then fixed to a fixed holder 13 integrally formed with the filter 10. In this case, the fixed holder 13 is folded by a thin-walled self-hinge a continuously formed on the fixed holder 13, and the catch claw b is locked to the locking part c, so that the dust collecting part 10a is removed. It is supposed to be fixed.

Further, since the current-carrying part 12 is composed of a current-carrying member 14 made of elastic metal plate attached to the electric air cleaner 11 so as to face the dust collecting part 10a,
When the air suction grill 9 is closed, the dust collector 10a is pressed to allow the electric air cleaner 11 to be accurately energized.
