As shown in fig. 1 and 2, the present invention provides an electric control box 100 disposed in an outdoor unit of an air conditioner, wherein the electric control box 100 includes: an electrical component 110, and a filter portion 120. The electric component 110 realizes automatic control of the air conditioner in the working process of the air conditioner, the electric component 110 is fixed on the main board 170, in the power-on working process, the main board 170 and the electric component 110 can generate heat, in order to dissipate the heat of the electric component 110, a heat dissipation air duct 180 is arranged in the electric control box 100, the electric component 110 is connected with the heat dissipation air duct 180, so that the heat dissipation air generated by the fan 230 enters the electric control box 100 and exchanges heat, and then flows out of the electric control box 100 (for example, the arrow direction in fig. 1 is the heat dissipation air direction). In this embodiment, one side of the cooling air flowing to the electrical component 110 is an air inlet side of the cooling air duct, and one side of the cooling air far away from the electrical component 110 is an air outlet side of the cooling air duct. The filtering portion 120 is disposed in the heat dissipation air duct 180 and located on a heat dissipation air inlet side of the electrical component 110, and the filtering portion 120 is configured to filter water drops in the heat dissipation air and also filter dust in the heat dissipation air.

In the above scheme, through setting up filter part 120 in the wind channel of dispelling the heat, the heat dissipation wind passes through behind the filter part again electric components, when the drop of water enters into automatically controlled box 100 inside through the drive of heat dissipation wind, the drop of water among the filter part 120 filtration heat dissipation wind (as solid arrow direction is the drop of water direction of motion in fig. 6, hollow arrow direction is the heat dissipation wind direction of flow) to make the drop of water can not be got rid of the electric components 110 region in the automatically controlled box 100, realize preventing that water from splashing the effect to electric components 110, improve electric components 110's reliability. The cooling air filtered by the filter unit 120 flows through the electronic component 110 and is blown out, and thus the cooling of the electronic component is not affected.

For convenience of structural description, in the present embodiment, the direction in which the filter part 120 and the electrical component 110 are oppositely disposed is the left-right direction, so that the heat dissipation air flows through the electrical component 110 along the left-right direction; the vertical direction in which the air conditioner is placed when in use is taken as the up-down direction, and the direction perpendicular to the left-right direction in a horizontal plane is taken as the front-back direction. In the specific structure of this embodiment, the electronic control box 100 further includes a housing 130, an inner cavity 131 and a heat dissipation air inlet 132 are disposed in the housing 130, the inner cavity 131 is used as a part of a heat dissipation air duct, and the heat dissipation air inlet 132 is located on an air inlet side of the heat dissipation air duct. The electrical component 110 is installed in the inner cavity 131, and the heat dissipation air inlet 132 is communicated with the inner cavity 131. The heat dissipation air inlet 132 is located at one side of the inner cavity 131 in the left-right direction, and the heat dissipation air enters the inner cavity 131 through the heat dissipation air inlet 132, so as to dissipate heat of the electrical component 110 in the inner cavity 131. The filter portion 120 is disposed in the heat dissipation air inlet 132, so that when the heat dissipation air with water drops passes through the filter portion 120, the heat dissipation air is filtered by the filter portion 120, and the water drops stay on the filter portion 120 and cannot contact the electrical component 110, which results in a short circuit of the electrical component 110.

As shown in fig. 3 and 4, the filter portion 120 in this embodiment is a filter screen, and is covered in the heat dissipation air inlet 132 through the filter screen, so that the water drops are adsorbed on the mesh wire of the filter screen after entering the electronic control box 100 along with the heat dissipation air, and thus the water drops are not allowed to enter the inner cavity 131.

In this embodiment, a filter screen is used as the filtering portion 120, and for enhancing the waterproof effect, the filter screen in this embodiment is located on one side of the water-introducing portion 140 departing from the electrical component 110. That is, the edge of the filter part 120 is located at the lower ends of the lower water guide surface 141 and the lower water guide surface 141, so that the distance between the filter part 120 and the electric component 110 is further increased, and when the water drops thrown onto the filter part 120 directly fall from the filter part 120 to the electric component 110, the water drops can be guided out through the lower water guide surface 141 and the upper water guide surface 142, and thus the water drops are prevented from falling into the inner cavity 131. And a better waterproof effect is achieved.

Thus, when the water drops on the water guide part 140 fall on the inclined surface 133, the water drops flow out of the electronic control box 100 on the inclined surface 133 due to the diversion of the inclined surface 133, and the water drops are not gathered in the electronic control box 100 and cannot be discharged. The outer wall of the connecting part of the shell 130 and the inclined plane 133 is provided with a clearance groove 134, the clearance groove is positioned between the inclined plane and the lower water diversion surface, and the clearance groove specifically comprises: the empty-avoiding groove 134 is located below the lower water-guiding surface 141, and the empty-avoiding groove is recessed toward the electrical component. The water drops on the lower water guide surface 141 slide down along the lower water guide surface 141 and slide down on the inclined surface 133 along the upper outer wall of the shell 130, and the water drops at the lower end of the lower water guide surface 141 can directly fall on the inclined surface 133 through the arrangement of the clearance groove 134, so that the influence on the waterproof effect of the electric control box 100 caused by the residual water drops on the shell 130 is avoided.
