(11) The push-out mechanism for the wind deflector provided by the embodiment of the present invention comprises a mounting housing 800, a rack 100, a gear 200, an intermittent movement mechanism, and a connecting rod 500.

(12) Herein, the mounting housing 800 is a supporting component of the push-out mechanism for the wind deflector, for providing a mounting base for other components.

(13) The rack 100 is slidably provided on the mounting housing 800. The rack 100 is used for hinging with a wind deflector 700. Specifically, a first hinge shaft 101 for hinging with the wind deflector 700 is provided on the rack 100. The rack 100 is used for driving the wind deflector 700 to push out forward. The gear 200 is rotatably provided on the mounting housing 800. The gear 200 is used for connecting with an output shaft of a motor, and used for outputting a power of the motor. The gear 200 is engaged with the rack 100, so as to drive the rack 100 to slide along an arc-shaped route. Therefore, the wind deflector 700 is pushed out forward, so that a gap is formed between a lower end of the wind deflector 700 and an air conditioner housing to ensure that when the wind deflector 700 swings subsequently, air conditioning wind can be received from both an upper and lower sides of the wind deflector 700 at the same time.

(14) The rack 100 is provided according to a movement track of the wind deflector 700, and preferably may be designed as a rack of an arc-shaped structure as shown in FIG. 1. The arc-shaped rack can achieve a displacement of a space state of the wind deflector 700, and is more conducive to space layout and less space occupation. Of course, racks with other structures such as a straight structure may also be used, and the present invention does not limit a specific shape of the rack.

(15) The intermittent movement mechanism is rotatably provided on the mounting housing 800. The intermittent movement mechanism comprises a first driving medium 300 rotating coaxially with the gear 200 and a second driving medium 400 drivingly connected with the first driving medium 300. The first driving medium 300 is rotated by the motor, and the second driving medium 400 is rotated by the first driving medium 300. The intermittent movement mechanism can convert the continuous rotation of the first driving medium 300 into a periodic movement and a stop of the second driving medium 400.

(16) One end of the connecting rod 500 is hinged to the second driving medium 400. Specifically, the connecting rod 500 is hinged with the second driving medium 400 through a hinge shaft 501 provided on the connecting rod 500. The other end of the connecting rod 500 is used for hinging with the wind deflector 700. Correspondingly, a second hinge shaft 502 for hinging with the wind deflector 700 is provided on the connecting rod 500. When the intermittent movement mechanism moves, the second driving medium 400 and the rack 100 drive the wind deflector 700 to open to a corresponding angle, and when the intermittent movement mechanism stops, the rack 100 drives the wind deflector 700 to continuously open to a final angle.

(17) As shown in FIG. 2, the push-out mechanism for the wind deflector provided by the present invention drives the first driving medium 300 and the gear 200 synchronous therewith through the motor, and may drive the rack 100 to move when the gear 200 and the first driving medium 300 rotate synchronously. The partial push-out action of the wind deflector 700 is achieved, so that the wind deflector 700 moves towards an outside, close to a middle position, of a wind outlet as far as possible to generate a gap, and an axis of the wind deflector 700 is driven by the rack 100 to displace, thereby achieving a transition from a totally enclosed wind deflector to an opened wind deflector.

(18) As shown in FIG. 3, the first driving medium 300 will drive the second driving medium 400 to rotate until the second driving medium 400 temporarily loses the slave power of the motor. At this time, a push-out and opening stroke of the wind deflector 700 has been completed.

(19) As shown in FIG. 4, when the second driving medium 400 loses the motor power, the wind deflector 700 may be continuously opened under a power action of the rack 100. However, the second driving medium 400 has no power to be applied to the wind deflector 700, but works under an indirect connection of the connecting rod 500 by serving as a rotation center of the wind deflector 700. When the motor moves clockwise and counterclockwise under the control of a program, it is a wind-sweeping action of the wind deflector 700. When the wind deflector 700 may reversely circulate according to a principle of the push-out mechanism for the wind deflector, the wind deflector 700 will be closed. The present invention may push the wind deflector 700 out by means of a left motor and a right motor and may achieve an up-down wind-sweeping action on the wind deflector, thereby saving the cost of one motor.

(20) In a specific embodiment of the present invention, the intermittent movement mechanism is a grooved wheel mechanism, the first driving medium 300 is a grooved wheel, and the second driving medium 400 is a drive plate with a cylindrical pin 401. The first driving medium 300 is a grooved wheel having at least one groove, and the grooved wheel as shown in FIG. 1 is a grooved wheel having four grooves. It should be noted that according to the required movement track, the structure of the grooved wheel may be freely designed. When the grooved wheel mechanism is actuated, it is used as a driving mechanism to drive the wind deflector 700 to push out. When the grooved wheel mechanism stops, that is, when the cylindrical pin 401 leaves the groove of the grooved wheel, it is converted into a driven mechanism for operation.

(21) In a specific embodiment of the present invention, the intermittent movement mechanism is an incomplete gear mechanism, and the incomplete gear mechanism is also a common intermittent movement mechanism. In a driving gear, only one or a few teeth are made, gear teeth engaged with the driving gear are made on a driven gear according to the requirements of movement time and stop time, and others are locking arcs. When two gear teeth come into engagement, as in a case of gear drive, a toothless portion is positioned by the locking arc, so that the driven gear is stationary.

(22) It should be noted that the first driving medium 300 is an incomplete gear, and the second driving medium 400 may be an incomplete gear or an incomplete rack. For the intermittent movement mechanism, an internal gear, an external gear, an internal rack, an external rack, an inner grooved wheel, an outer grooved wheel and like may be selected as required.

(23) In order to ensure smooth sliding of the rack 100, the embodiment of the present invention further comprises a guide mechanism provided on the mounting housing 800 and used to guide the rack 100. The arrangement of the guide mechanism should be set according to a movement route of the rack 100 to ensure that the rack 100 smoothly slides along a predetermined route.

(24) In the present embodiment, the guide mechanism is a guide wheel 600 rotatably provided on the mounting housing 800. That is, the guide wheel and the rack 100 are in rolling friction, and the friction is smaller, which is more conducive to the sliding of the rack 100.

(25) Further, the rack 100 is an arc-shaped rack, and an arc-shaped groove 102 concentric with the rack 100 is provided on the rack 100, the push-out mechanism for a wind deflector comprises a plurality of guide wheels, at least one of the guide wheels 600 is matched with the arc-shaped groove 102, and the other one of the guide wheels 600 are matched with an edge of the rack 100. In the present embodiment, one guide wheel 600 is matched with the arc-shaped groove 102, and two guide wheels 600 are matched with the edge of the rack 100.

(26) A guide groove is provided on an outer circumferential surface of the guide wheel 600, the rack 100 is matched with the guide groove. By means of the guide groove, the guide wheel 600 may not only limit the movement of the rack 100 in a direction perpendicular to an axis of the guide wheel 600, but also limit the movement of the rack 100 in a direction parallel to the axis of the guide wheel 600.

(27) The present invention also discloses an air conditioner. The air conditioner comprises the push-out mechanism for a wind deflector disclosed in the above embodiments, and thus has all the technical effects of the above embodiments, which will not be elaborated herein again.

(28) The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be applied to other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but it is to comply with the broadest scope consistent with the principles and novel features disclosed herein.
