Embodiment 1
[0034] This embodiment discloses an air conditioner, the air conditioner is provided with an air supply system 10, the air supply system 10 includes a housing, a centrifugal fan 13 is arranged in the housing, and an upper air duct 11 and a lower air duct 12 are formed in the housing , which are all in communication with the centrifugal fan 13, and the wind flows through the upper air duct 11 and the lower air duct 12 at the same time when the centrifugal fan 13 is working. An upper air outlet 111 is formed on the upper air passage 11 , and an lower air outlet 121 is formed on the lower air passage 12 . When the centrifugal fan 13 worked, the wind blown from the upper air outlet 111 through the upper air duct 11 was blown to the top of the room where the air conditioner was located, and the wind blown from the lower air outlet 121 through the lower air duct 12 was blown to the bottom of the room where the air conditioner was located. The air conditioner can realize wind blowing...

The invention relates to an air stop mechanism. The air stop mechanism comprises a cam, a first motor controlling the cam to rotate, and a ratchet wheel air stop assembly; the ratchet wheel air stop assembly comprises a ratchet wheel, an air baffle fixed to the ratchet wheel, and a second motor driving the ratchet wheel and the air baffle to rotate; the ratchet wheel comprises a wheel body and ratchet teeth formed on the periphery of the wheel body, and ratchet grooves are formed between the ratchet teeth; and the cam is provided with a short-diameter large end and a long-diameter small end. The cam is rotatably matched with the ratchet wheel, wherein when it is needed to adjust the angle of the air baffle, the second motor drives the ratchet wheel and the air baffle on the ratchet wheel to rotate, and the first motor controls the cam to rotate to make the cam separated from the ratchet grooves and not interfere with rotation of the ratchet teeth; and when the air baffle is rotated toa set angle or a preset angle, the second motor is stopped, the first motor drives the cam to rotate to make the long-diameter small end of the cam clamped into the corresponding ratchet groove, and then the air baffle is fixed. An air supply system with the air stop mechanism can realize adjustment of the air volume and / or the opening and closing of an air channel and / or the air supply direction.
Description
technical field [0001] The invention relates to a wind shielding mechanism, an air supply system, an air conditioner and a control method thereof, and belongs to the technical field of refrigeration equipment. Background technique [0002] The existing air supply system with a centrifugal fan can realize the air conditioner with two-way air outlet, and only has the function of two-way air outlet at the same time during work. The air conditioner that realizes two-way air outlet, such as the air conditioner with upper and lower air outlets. Without a windshield mechanism, the wind coming out of the centrifugal fan can only flow out from the two air outlet ducts at the same time. It cannot satisfy the air outlet function that the user wants to select only the upper air outlet or only the lower air outlet. An air supply system with double air ducts or multiple air ducts is provided, and an air outlet reversing device is arranged between the centrifugal fan and the air inlets of...
