The invention provides an air conditioner, and aims to solve the problem that the existing air conditioner cannot acquire the accurate position of a user. The air conditioner can be a split machine, such as a cabinet machine, a hanging machine, a ceiling machine and an air duct machine, wherein the cabinet machine can be a square cabinet machine or a round cabinet machine; for a circular cabinet air conditioner, the circular cabinet air conditioner is provided with a roughly cylindrical shell, a long strip-shaped air outlet extending downwards from the top is formed in the shell, and a cross-flow wind wheel corresponding to the air outlet is arranged in the shell. Of course, the air conditioner may be a unified machine such as a window machine and a mobile air conditioner.
As shown in fig. 1 to 4, to achieve the above object, the present invention provides an air conditioner 100, which includes a housing 1 and an electric control board (not shown), the air conditioner 100 further includes a position monitoring device 2, and the position monitoring device 2 is disposed on the housing 1. The position monitoring device 2 comprises a radar sensor 23, a first shielding ring 21, a second shielding ring 22 and a driving device 24, wherein the radar sensor 23 is electrically connected with the electric control board; the first shielding ring 21 is arranged around the periphery of the radar sensor 23, and the first shielding ring 21 can shield radar waves of the radar sensor 23; the second shielding ring 22 is arranged around the periphery of the first shielding ring 21, and the second shielding ring 22 can also shield the radar wave of the radar sensor 23; one of the first shielding ring 21 and the second shielding ring 22 is provided with a plurality of first wave feeding ports 211, and the other is provided with a second wave feeding port 221; the driving device 24 is connected to the first shielding ring 21 or the second shielding ring 22 with the second wave feeding port 221, so as to drive the first shielding ring 21 or the second shielding ring 22 to move, and the second wave feeding port 221 corresponds to the plurality of first wave feeding ports 211 one by one. When the second wave feeding port 221 corresponds to any one of the first wave feeding ports 211, the radar waves of the radar sensor 23 can pass through the first wave feeding port 211 and the second wave feeding port 221 to detect a detected object, which is the user 200 in this embodiment.
When the position monitoring device 2 in the air conditioner 100 of this embodiment is in operation, the radar sensor 23 is turned on, and the driving device 24 drives the first shielding ring 21 or the second shielding ring 22 to move, so as to adjust the position of the second wave feeding port 221. In the process of moving the first wave feeding ring or the second wave feeding ring, the second wave feeding port 221 corresponds to one of the first wave feeding ports 211, the radar wave of the radar sensor 23 is emitted through the second wave feeding port 221 and the first wave feeding port 211 to detect whether the user 200 exists in the radar wave region emitted by the radar sensor 23, and the propagation angle of the radar wave of the radar sensor 23 after passing through the second wave feeding port 221 and the first wave feeding port 211 is small, so that the position of the user 200 can be determined in a specific range. If the user 200 is detected to exist, the first shielding ring 21 or the second shielding ring 22 stops moving, that is, the second wave feed port 221 stops moving, the distance between the user 200 and the air conditioner 100 is determined through the doppler effect, the emission angle of the radar wave of the radar sensor 23 is determined according to the movement amount of the second wave feed port 221, and then the accurate position of the user 200 is determined according to the emission angle of the radar wave and the distance between the user 200 and the air conditioner 100. If the user 200 is not detected to be present, the first shielding ring 21 or the second shielding ring 22 continues to move to adjust the position of the second wave feeding port 221 until the user 200 is detected to be present, so as to monitor the position of the user 200 in real time.
The air conditioner 100 of this embodiment can obtain the accurate location of the user 200 through the location monitoring device 2, and further adjust the wind direction of the air conditioner 100 according to the location information of the user 200, so that the user 200 can obtain a comfortable feeling.
