Referring to FIG. 1, an indoor unit 10 of an air conditioner according to an embodiment of the present invention includes a chassis 11 provided with a stabilizer 111 for generating air flow on a front surface thereof, and a rear surface of the chassis 11. A base 12 fixed to an installation wall, a front frame 13 coupled to the front of the chassis 11, and a suction grill 131 formed on an upper surface thereof, and the front frame 13. Included is a front panel 14 that is movably coupled to the front of the.
In addition, the indoor unit 10 has an inner panel 15 which is linked to the rear surface of the front panel 14 and is provided on the front frame 13 so as to be rotatable, and the front frame 13 and the chassis ( 11, a heat exchanger 19 provided between the supporter, a fan 20 provided below the heat exchanger 19 to suck and discharge indoor air, and a lower end of the heat exchanger 19 to support the discharge port. Included is a discharge grill 16 is provided.
In addition, the indoor unit 10 includes a discharge vane 21 for selectively shielding the discharge port, a discharge louver 22 provided at the discharge port and adjusting the discharge direction of air together with the discharge vane 21; A bottom plate 23 for shielding the pipe passing through the lower end of the indoor unit 10 and a tubing holder 24 rotatably coupled to the chassis 11 to support the pipe are included.
In addition, the indoor unit 10 includes a pre-filter 17 and a pre-filter 17 for purifying air sucked through the front surface of the front frame 13 and the suction grille 131. A dust collecting filter 18 provided between the heat exchangers 19 is included.
2 is an external perspective view showing an operating state of the indoor unit of the air conditioner according to the embodiment of the present invention.
2, the indoor unit 10 of the air conditioner according to the embodiment of the present invention has a structure in which a discharge grill 16 having a discharge port is provided at a lower end of the indoor unit 10. That is, the discharge port is located at the bottom of the indoor unit 10, and the discharge vane 21 and the discharge louver 22 are provided at the discharge port. Therefore, the sucked indoor air passes through the heat exchanger 19 and then is discharged to the bottom of the indoor unit 10.
In addition, the front panel 14 is raised while being rotated by the link member 26 for indoor air intake. In detail, the front panel 14 is raised in a form in which the upper end is inclined forward by the rotation of the link member 26. Therefore, indoor air is sucked through the suction grille 131 and sucked through the space formed between the front frame 13 and the front panel 14. At this time, the inner panel 15 provided on the rear surface of the front panel 14 is kept fixed to the front surface of the front frame 13.
In addition, the bottom edge of the indoor unit 10 is equipped with a moving sensor assembly 27 for detecting the movement of the human body.
In detail, the moving sensor assembly 27 is introduced into the indoor unit 10 when the indoor unit 10 is not operated, and descends when the indoor unit 10 operates to protrude from the bottom surface of the indoor unit 10. do. The moving sensor assembly 27 is rotatably installed at a predetermined angle about the vertical axis.
As such, since the moving sensor assembly 27 protrudes a predetermined length from the bottom of the indoor unit 10 and is rotatably installed in the left and right directions, the moving sensor assembly 27 has an advantage of widening the range of detecting the movement of the human body.
Hereinafter, the configuration and operation of the moving sensor assembly 27 will be described in more detail with reference to the accompanying drawings.
 3 and 4 are perspective views of a moving sensor assembly mounted to the air conditioner indoor unit according to the embodiment of the present invention.
3 and 4, the moving sensor assembly 27 according to the embodiment of the present invention includes a frame 271 having a hollow portion formed therein, a case 272 fitted to and elevated by the hollow portion, A plurality of moving sensors 277 provided inside the case 272, a motor bracket 274 fixed to the case 272, a rotating motor 278 seated on the motor bracket 274, A rotating bracket 275 connected to a rotating shaft of the rotating motor 278 to rotate, a plurality of moving sensors 277 mounted on the rotating bracket 275 to detect movement of an object, particularly a human body, and the frame A lift motor 279 mounted on an outer surface of 272 and a pinion 273 provided on a rotation shaft of the lift motor 279 are included.
In detail, a rack 272b meshing with the pinion 273 is formed in an up and down direction on one side of the edge of the case 272, and a guide protrusion 272a protrudes on the other side. In addition, a guide rail 276 is formed in the frame 271 in order to accommodate the guide protrusion 272a and guide the case 272 up and down stably.
In more detail, both ends of the motor bracket 274 are bent downward and coupled to the edge of the case 272. The rotating motor 278 is mounted on the motor bracket 274. Therefore, the case 272 and the rotating motor 278 are movable in one body in the vertical direction. In addition, the rotation bracket 275 is accommodated in the case 272 while being coupled to the rotation shaft of the rotation motor 278. Then, by the rotation of the motor 278 is rotated by a predetermined angle in the forward or reverse direction. In addition, the lifting motor 179 rotates the pinion 273 in a state of being fixed to the frame 271. Then, the rack 272b coupled with the pinion 273 is raised or lowered. Here, since the rack 272b is integrally formed at the edge of the case 272, the case 272 is moved in the vertical direction by the driving of the lifting motor 279. The frame 271 is fixed to the bottom of the indoor unit 10.
Hereinafter, the operation of the moving sensor assembly 27 will be described.
First, when an operation signal is input to the indoor unit 10, the front panel 14 is raised to open the front suction port, and the discharge vane 21 is rotated to open the discharge port. Then, power is applied to the lifting motor 279, and the pinion 273 connected to the rotating shaft of the lifting motor 279 rotates. Then, the rack 272b engaged with the pinion 273 is lowered so that the case 272 protrudes from the bottom surface of the indoor unit 10. In addition, when the rotating motor 278 is operated, the rotating bracket 275 is rotated so that the moving sensor 277 is rotated a predetermined angle to the left or the right.
Meanwhile, a plurality of moving sensors 277 may be mounted on the rotation bracket 275. In addition, the plurality of moving sensors 277 may be mounted to face in different directions to allow a wider detection range.
In addition, the case 272 is detachably coupled to the frame 271, so that the combination of the case 272, the moving sensor 277, the motor bracket 274, and the rotating motor 278 is one. The module may be provided in a replaceable form. In other words, when the case 272 is pulled upward, the guide protrusion 272a rises along the guide rail 276, and the case 272 is the frame 271 at the moment when the guide 276a leaves the guide rail 276. Separated from.
According to the above configuration, since the moving sensor 277 protrudes a predetermined length downward from the bottom of the indoor unit 10 and is rotatable in the left and right directions, the moving sensor 277 does not protrude from the bottom of the indoor unit 10. Compared with the sensing means fixed to the indoor unit 10, the detection range can be expanded.
