[0016] (1) Existing air outlet grilles cannot prevent clogging. After long-term use, dust will clog the grilles, affecting the air volume and requiring frequent cleaning. This application sets an anti-clogging component on one side of the grille body. When the fan is working, it blows air to remove dust or snow from the grille body, achieving the effect of unblocking. By setting a horizontal moving unit between the moving frame and the fan, the fan can move horizontally to unblock the grille body.

[0017] (2) By opening a sliding groove on the inner wall of the moving frame and opening a groove at the bottom of the sliding groove, the second lead screw is movably installed in the groove. When the second servo motor works, it drives the second lead screw to rotate. The second lead screw moves through the moving slider and the moving slider is engaged in the groove. Thus, the moving slider moves and drives the lower fan to move, clearing the dust on the grille body. By setting the air guide hood, the airflow speed can be increased and the clearing effect can be improved.

[0018] (3) Two sets of rectangular plates are fixedly installed on the outer wall of the fan. The shaft is fixedly inserted through the two sets of rectangular plates, and the two ends of the shaft are movably installed on the corresponding arc plate. Multiple sets of clip holes are opened through one side of the arc plate. Limiting columns are fixedly connected to the outer wall of one side of the rectangular plate. The limiting columns movably insert through the corresponding clip holes. During the installation process, the tilt angle of the fan can be adjusted according to the specific situation of the grille body. Attached Figure Description

The lifting block 15 and the first lead screw 13 are connected. The first lead screw 13 movably passes through the lifting block 15, and the lifting block 15 and the first lead screw 13 are in a transmission cooperation. The horizontal moving unit includes a second lead screw 23 and a connecting part. The connecting part is located between the moving frame 11 and the fan 17. The connecting part includes a moving slider 24, an arc plate 28 and a rectangular plate 26. The rectangular plate 26 and the arc plate 28 are movably connected and are fixedly positioned.

[0028] It should be noted that the flow fan 17 is existing technology and will not be described in detail here.

[0029] Specifically, existing air outlet grilles cannot prevent clogging. After long-term use, dust will clog the grille, affecting the airflow and requiring frequent cleaning. This application solves this problem by setting an anti-clogging component on one side of the grille body 10. When the fan 17 is working, it blows airflow to remove dust or snow from the grille body 10, achieving a clearing effect. By setting a horizontal moving unit between the moving frame 11 and the fan 17, the fan 17 can move horizontally to clear the grille body 10. By setting a lifting unit, the moving frame 11 can move vertically, thereby achieving overall anti-clogging of the grille body 10. The practicality of this device is improved through reasonable structural design.

[0030] The lifting unit also includes a first lifting limiting groove 12 and a second lifting limiting groove 16 fixedly connected to both sides of the grille body 10. A first lead screw 13 is movably installed in the cavity of the first lifting limiting groove 12. The lifting block 15 is L-shaped, with one end fixedly connected to the moving frame 11 and the other end movably engaged with the first lifting limiting groove 12. A first servo motor 14 is fixedly installed at the top of the first lifting limiting groove 12. The output shaft of the first servo motor 14 movably passes through the first lifting limiting groove 12 and is fixedly connected to one end of the first lead screw 13. The first lead screw 13 and the lifting block 15 are connected by a thread. A guide rod 19 is fixedly installed in the cavity of the second lifting limiting groove 16.

One end of the guide block 20 movably engages with the second lifting limiting groove 16, and the guide rod 19 movably passes through the guide block 20.

[0031] Specifically, by setting a first lifting limit groove 12 and a second lifting limit groove 16 to be fixedly connected to the grid body 10, a first lead screw 13 is movably installed in the cavity of the first lifting limit groove 12, one end of the lifting block 15 is fixedly connected to the moving frame 11, and the other end of the lifting block 15 is movably engaged with the first lifting limit groove 12. The first lead screw 13 movably passes through the lifting block 15. When the first servo motor 14 is working, it drives the first lead screw 13 to rotate. The lifting block 15 and the first lead screw 13 are in transmission cooperation, so that the moving frame 11 can be lifted and lowered. By setting a guide rod 19 to be fixedly installed in the cavity of the second lifting limit groove 16, the guide rod 19 movably passes through the guide block 20, and the guide block 20 is fixedly connected to the moving frame 11, ensuring that the moving frame 11 is lifted and lowered in the direction of the guide rod 19.

[0032] The movable frame 11 is located between the first lifting limit groove 12 and the second lifting limit groove 16. A sliding groove 21 is provided on the inner wall of the movable frame 11, and a groove 22 is provided at the bottom end of the sliding groove 21.

The movable slider 24 is movably engaged in the groove 22. The second lead screw 23 and the movable slider 24 are connected by a thread.

[0033] Specifically, a groove 21 is opened on the inner wall of the movable frame 11, and a groove 22 is opened at the bottom end of the groove 21. The second lead screw 23 is movably installed in the groove 22. When the second servo motor 18 works, it drives the second lead screw 23 to rotate. The second lead screw 23 moves through the movable slider 24, and the movable slider 24 is engaged in the groove 22. Thus, the movable slider 24 moves and drives the lower airflow fan 17 to move, clearing the dust on the grille body 10. By setting the air guide hood 25, the airflow speed can be increased, and the clearing effect can be improved.

[0034] Two sets of rectangular plates 26 are fixedly installed on the outer wall of the fan 17. A shaft 27 is fixedly connected to both sets of rectangular plates 26. The two ends of the shaft 27 are movably installed on corresponding arc-shaped plates 28. The shaft 27 and the movable slider 24 are parallel to each other. Two sets of arc-shaped plates 28 are movably engaged within the slide groove 21.

During the installation process, the tilt angle of the fan 17 can be adjusted according to the specific situation of the grille body 10.

[0036] The working principle of the air inlet and outlet grille structure of the outdoor unit of a heat pump disclosed in this application is as follows: By setting an anti-clogging component on one side of the grille body 10, the airflow fan 17 blows air to remove dust or snow on the grille body 10 during operation, thereby achieving a clearing effect. By setting a horizontal moving unit between the moving frame 11 and the airflow fan 17, the airflow fan 17 can move horizontally to clear the grille body 10. By setting a lifting unit, the moving frame 11 can move vertically, thereby achieving overall anti-clogging of the grille body 10.
