Embodiment Construction
[0051] As shown in Figures 1 and 2, the air conditioner indoor unit of the present invention includes a base 50, a casing 60, an outlet unit 80, and an elevating mechanism for the outlet unit. The casing 60 is provided on the upper side of the base 50, and has air inlets 72 formed on the left and right sides, respectively, and air outlets 74 formed on the upper surface. The discharge port unit 80 is provided on the air discharge port 74 of the casing 60 in a liftable manner, and is used to distribute the air discharged to the air port 74 to the front and both sides. The discharge port lifting mechanism is formed on the discharge port unit 80 and the casing 60, and can move the discharge port unit 80 up and down to open and close the air discharge port 74. As shown in FIG.
[0052] The upper surface of the casing 60 is an open structure, forming the air discharge port 74, which is closed as the discharge port unit 80 descends and opened as the discharge port unit 80 ascends.

The lift mechanism of exhaust unit of air conditioner includes a driven nut formed in the exhaust unit on the casing; a lifting motor set on the casing coaxially with the driven nut; a driving screw fixed on the rotating shaft of the lifting motor to mesh with the driven nut and capable of rotating; and a screw rack mounted in the lower end of the driving screw for the driving screw to rotate on. Inside the air exhaust on the casing, an exhaust unit guiding part is set for guiding the lift of the exhaust unit, and the lifting motor is mounted on the supporting frame on the lower end of the exhaust unit. The present invention makes the casing more beautiful and can avoid foreign matter to enter the exhaust, and the lift mechanism has simple structure and easy operation.
Description
technical field [0001] The invention relates to a lifting mechanism for an air conditioner outlet unit. Background technique [0002] Generally, an air conditioner is composed of a compressor, a condenser, an expander, and an evaporator. An air conditioner is a device that uses the refrigeration cycle of a refrigerant to cool or purify indoor air. Provide users with a more comfortable indoor environment. [0003] As shown in Fig. 8 Fig. 9, the structure of existing air conditioner indoor unit comprises base 2, shell 4, front upper panel 10, front lower panel 14, left and right suction grille 16, air blower 18, heat exchanger 20. The casing 4 is provided on the upper side of the rear part of the above-mentioned base 2, and its front has an open structure. The front upper panel 10 is arranged on the front upper part of the above-mentioned housing 4, and the front center of both sides are respectively formed with a discharge port 6, left and right discharge ports 8. The fro...
