An electromagnet is provided above the blade, and a permanent magnet is provided on the outer surface of the blade. When the air conditioner is powered on and running, the electromagnet is also powered on and generates magnetism. During the operation of the air conditioner, the air outlet blows out air, blowing the blade movably mounted on the rotating shaft outwards, making the permanent magnet on the blade approach the electromagnet. The electromagnet attracts the permanent magnet, fixing the blade in a horizontal position, so that the air outlet opens and can blow out air normally. When the air conditioner shuts down and stops running, the air outlet no longer blows out air. At the same time, the electromagnet is powered off, and the blade returns to the vertical state under the action of gravity, closing the air outlet to prevent external rainwater and dust from entering the outer casing of the unit and corroding the internal components of the air conditioner. The anti-corrosion function can be realized without changing the original structure of the outdoor unit of the air conditioner.

[0014] 2. The blade is horizontally arranged. After being blown up by the air from the air outlet and attracted by the electromagnet, the blade is horizontally arranged outside the protection component, playing a shielding role above the front side of the protection component. When using the air conditioner on a rainy day, it can prevent rainwater from entering the outer casing of the unit while not affecting the air outlet.

[0015] 3. The blade is provided with a diversion groove. When the air conditioner is running and the blade extends, if it encounters a rainy day, the blade plays a shielding role above the front side of the protection component. Rainwater falls on the blade and gathers in the diversion groove, flowing towards both ends of the blade along the diversion groove. Inside the outer casing of the unit, between the protection component and the outer casing, there is an annular water guide groove. The rainwater enters the water guide groove through the diversion groove on the blade and is discharged through the grid at the air outlet of the outer casing of the unit.

[0016] 4. The surface of the outer casing of the unit is sprayed with an anti-corrosion coating, and the surface of the blade is sprayed with an anti-corrosion coating. After the anti-corrosion coatings are applied to the surfaces of the outer casing of the unit and the blade, an anti-corrosion topcoat is sprayed on the outer surface of the anti-corrosion coating to prevent acidic rainwater from corroding the outer casing of the unit and the blade and extend their service life.

[0024] The present utility model will be further described below with reference to the accompanying drawings.

[0025] All orientations mentioned in this specification are based on the orientation when a corrosion-proof housing of an air conditioner outdoor unit of the present utility model is working properly, without limiting its orientation during storage and transportation, only representing relative positional relationships and not absolute positional relationships.

[0026] As Figures 1 to 6 Collectively shown, a corrosion-proof housing of an air conditioner outdoor unit includes an outdoor unit housing 1 arranged outdoors. An air conditioner component is installed inside the outdoor unit housing 1. An air outlet 2 is provided on the front side of the outdoor unit housing 1. Inside the outdoor unit housing 1, at the position of the air outlet 2, a protection component 3 for blocking the air outlet 2 is installed. There is a certain gap between the protection component 3 and the outdoor unit housing 1 at the air outlet 2. The protection component 3 includes an outer frame 301 clamped to the outdoor unit housing 1. A rotating shaft 302 is installed inside the outer frame 301. The rotating shaft 302 extends along the transverse direction of the outer frame 301 and connects the left and right inner side walls of the outer frame 301. A blade 303 is movably installed on the rotating shaft 302. Above the blade 303, at the outer side part of the rotating shaft 302, an electromagnet 304 is installed. The electromagnet 304 extends along the length direction of the rotating shaft 302 and connects the left and right inner side walls of the outer frame 301. Outside the blade 303, at the upper part of the blade 303, a permanent magnet 305 attracted to the electromagnet 304 is provided.

[0027] There are several blades 303. Several blades 303 with the same width are spliced in sequence to cover the opening range of the outer frame 301. The blades 303 are arranged horizontally. When the blades 303 are blown up by the wind at the air outlet 2 and are attracted by the electromagnet 304, the blades 303 are arranged horizontally in front of the protection component 3, playing a role in blocking the upper front side of the protection component 3. When using the air conditioner on a rainy day, while not affecting the air outlet, it can also prevent rainwater from entering the outdoor unit housing 1.

[0028] The blade 303 is provided with a diversion groove 306; the diversion groove 306 has a structure with a high center and low ends, and its cross-section is a "V" shape. When the air conditioner is running and the blade 303 extends, in case of rain, the blade 303 shields the upper front side of the protection component 3. Rainwater falls on the blade 303 and gathers in the diversion groove 306, flowing towards both ends of the blade 303 along the diversion groove 306; inside the outer machine housing 1, between the protection component 3 and the outer machine housing 1, there is an annular water guide groove. The rainwater enters the water guide groove through the diversion groove 306 on the blade 303 and is discharged through the grid at the air outlet 2 of the outer machine housing 1.

[0029] The blade 303 is made of plastic material. The blade 303 made of plastic material is light in weight. While being able to shield rainwater, it can also be easily blown up by the wind at the air outlet 2 and thus be attracted by the electromagnet 304.

[0030] The surface of the outer machine housing 1 is sprayed with an anti-corrosion coating, and the surface of the blade 303 is also sprayed with an anti-corrosion coating; after the surfaces of the outer machine housing 1 and the blade 303 are coated with the anti-corrosion coating, an anti-corrosion topcoat is sprayed on the outer surface of the anti-corrosion coating to prevent the outer machine housing 1 and the blade 303 from being corroded by acidic rainwater.

[0031] When the air conditioner is powered on and running, the electromagnet 304 is also powered on and generates magnetism. During the operation of the air conditioner, air blows out at the air outlet 2, blowing the blade 303 movably mounted on the rotating shaft 302 outwards, making the permanent magnet 305 on the blade 303 approach the electromagnet 304. The electromagnet 304 attracts the permanent magnet 305, fixing the blade 303 in a horizontal position, so that the air outlet 2 is opened and can blow out air normally; when the air conditioner shuts down and stops running, the air outlet 2 no longer blows out air. At the same time, the electromagnet 304 is powered off, and the blade 303 returns to the vertical state under the action of gravity, closing the air outlet 2 to prevent external rainwater and dust from entering the outer machine housing 1 and corroding the internal components of the air conditioner.

[0032] Certainly, the above description is not a limitation of the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the essence of the present utility model should also fall within the protection scope of the present utility model.
