The present invention will now be described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, and merely illustrates the basic structure of the present invention in a schematic manner, and therefore it shows only the constitution related to the present invention.

In the description of the present invention, it is to be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner and are not to be construed as limiting the present invention.

Referring to fig. 1-3, the automatic drainage mechanism 100 of the present invention is shown in an overall elongated shape, and the drainage mechanism 100 mainly includes a housing formed by a lower box 10 and a box cover 20, a motor 30, a rotating wheel 40 engaged with a motor shaft of the motor 30, a water plug 50, a transmission rope 60 connecting the rotating wheel 40 and the water plug 50, and a spring 70 having one end fixed to the lower box 20 and the other end abutting against the water plug 50.

The motor 30 is arranged at the upper right side of the drainage mechanism 100, so that the motor 30 is far away from the water level line as far as possible, the use reliability of the drainage mechanism is improved, the rotating wheel 40 is arranged below the motor 30 and fixed on the motor shaft and driven by the motor 30, and the rotating wheel 40 drives the water plug 50 through the transmission rope belt 60. In order to facilitate the matching of the rotating wheel 40 and the transmission rope 60, a circle of groove 41 is formed in the periphery of the rotating wheel, so that the transmission rope 60 can be conveniently wound on the rotating wheel 40 to move.

The left side of the lower box body 10 is provided with a rotating shaft 80, the water plug 50 is approximately in an "n" shape, one end of the water plug 50 is provided with a "C" shaped notch 51, the other end of the water plug 50 is fixedly provided with a rubber head 52 so as to improve the sealing performance of the water plug 50 and the drain hole, one end of the water plug 50 provided with the "C" shaped notch 51 is positioned in the shell of the drainage mechanism 100, the other end provided with the rubber head 52 is positioned outside the shell of the drainage mechanism 100, and the water plug 50 is rotatably and fixedly connected to the rotating shaft 80 through the "C" shaped notch 51. Because the two ends of the existing universal rotating shaft are large and the middle is small, the design of the C-shaped notch 51 solves the problem of assembling the water plug 50 and the rotating shaft 80.

When the motor 30 is in a closed state, the rubber head 52 of the water plug 50 is engaged with the drainage hole of the chassis 200 under the elastic force of the spring 70, and the drainage mechanism 100 is in a closed state. When the motor 30 rotates in the forward direction, the motor 30 drives the water plug 50 to rotate around the rotating shaft 80 through the rotating wheel 40 and the transmission rope 60, the rubber head 52 of the water plug 50 is separated from the water drainage hole, so that the drainage mechanism 100 is opened, when the motor 30 rotates in the reverse direction, the transmission rope 60 is released, the rubber head 52 of the water plug 50 is matched with the water drainage hole again under the elastic force of the spring 70, and the drainage mechanism 100 returns to the closed state.

The automatic drainage mechanism 100 is transversely installed on a base plate 200 of the air conditioner, a bottom plate 210 of the base plate 200 is provided with a recessed area with the height of 2mm-3mm, a drain hole is formed in the recessed area to facilitate drainage, the automatic drainage mechanism 100 is matched with the drain hole, the transverse installation can greatly reduce the longitudinal space occupied by the drainage mechanism 100, and the interior of a common product of the existing integrated air conditioner can have loose transverse space, so that the design can fully utilize the residual space in the product according to the existing layout of the product, and the product does not need to reserve the longitudinal space to install the drainage mechanism 100. The water plug 50 is matched with the drainage hole in a rotating mode, so that the water plug 50 and the drainage hole do not need to be designed coaxially, and the water plug is one of key points for realizing transverse installation of the automatic drainage mechanism 100.

The factors such as product cost, use reliability and service life are comprehensively considered, the motor 30 adopts a stepping motor, the spring 70 is a pressure spring, and the transmission rope 60 adopts a steel wire rope. Through precise calculation in combination with the elastic force of the spring 70, the traction force of the motor 30, the lever action of the rotating wheel 40 and the water plug 50, and the like, it is finally ensured that sufficient elastic force is converted into the force of blocking and pressing the water drain hole by the water plug when the drainage mechanism 100 is in a closed state, and water leakage is ensured when the drainage mechanism is in the closed state. Meanwhile, the water discharging mechanism 100 is ensured to have balance between the elastic force of the spring 70 and the traction force of the motor 30 in the opening state, so that the water plug 50 can be pulled, the opening state can be maintained, and sufficient margin is provided.
