The electric control box includes a housing (1); a cooling fin (2) running through the housing (1) and having a part located inside the housing (1) and another part located outside the housing (1); an inner water-guiding part (3) located inside the housing (1) and below the cooling fin (2); an outer water-guiding part (4) located outside the housing (1) and below the inner water-guiding part (3), the inner water-guiding part (3) and the outer water-guiding part (4) defining a water guide passage (a) configured to guide water (b) inside the housing (1) to the outside of the housing (1). ## Claims ### Claim 1 An electric control box for an air conditioner, comprising: a housing; a cooling fin running through the housing, the cooling fin having a part located inside the housing and another part located outside the housing; an inner water-guiding part extending from the housing a distance into the housing and positioned below the cooling fin; an outer water-guiding part extending from the housing a distance out of the housing and positioned below the inner water-guiding part, the inner water-guiding part and the outer water-guiding part defining a water guide passage configured to guide water inside the housing to the outside of the housing and wherein the housing defines an opening, and a lower edge defining the opening is bent towards the inside of the housing to form the inner water-guiding part, and a water shield located outside the housing and covering the opening and the outer water-guiding part, the water shield defining a through hole in a lower part thereof. ### Claim 2 (depends on 1) The electric control box according to claim 1, wherein the inner water-guiding part and the outer water-guiding part are located at the opening, and an upper edge defining the opening is bent towards the outside of the housing to form a water guide plate. ### Claim 3 (depends on 2) The electric control box according to claim 2, wherein the water guide plate includes a curved portion. ### Claim 4 (depends on 3) The electric control box according to claim 3, wherein the water guide plate protrudes towards the cooling fin. ### Claim 5 (depends on 1) The electric control box according to claim 1, wherein the inner water-guiding part and the outer water-guiding part are integrally formed. ### Claim 6 (depends on 1) The electric control box according to claim 1, wherein at least one of the inner water-guiding part and the outer water-guiding part is welded to the housing. ### Claim 7 (depends on 1) The electric control box according to claim 1, wherein the inner water-guiding part has a curved portion and is diagonally shaped. ### Claim 8 (depends on 7) The electric control box according to claim 7, wherein the inner water guiding part protrudes towards a direction away from the cooling fin. ### Claim 9 (depends on 1) The electric control box according to claim 1, wherein the outer water-guiding part has a lower end inclining towards a direction away from the housing, in a direction away from the cooling fin. ### Claim 10 (depends on 1) The electric control box according to claim 1, wherein a perpendicular distance between an end of the inner water-guiding part adjacent to the cooling fin and a corresponding position on the housing is L1, and a portion of the cooling fin adjacent to the inner water-guiding part extends into the housing by a length L2, in which L1≥L2. ### Claim 11 (depends on 1) The electric control box according to claim 1, wherein the cooling fin is connected to the housing by means a threaded fastener. ### Claim 12 (depends on 1) An air conditioner, comprising an electric control box according to claim 1. ### Claim 13 (depends on 1) The electric control box according to claim 1, wherein the outer water-guiding part has a lower end inclining towards a direction away from the housing, in a direction away from the cooling fin. ### Claim 14 (depends on 1) The electric control box according to claim 1, wherein a perpendicular distance between an end of the inner water-guiding part adjacent to the cooling fin and a corresponding position on the housing is L1, and a portion of the cooling fin adjacent to the inner water-guiding part extends into the housing by a length L2, in which L1≥L2. ### Claim 15 (depends on 1) The electric control box according to claim 1, wherein the cooling fin is connected to the housing by means a threaded fastener. ### Claim 16 (depends on 1) An air conditioner, comprising an electric control box according to claim 1. ### Claim 17 An electric control box for an air conditioner, comprising: a housing; a cooling fin running through the housing, the cooling fin having a part located inside the housing and another part located outside the housing; an inner water-guiding part extending from the housing a distance into the housing and positioned below the cooling fin; an outer water-guiding part extending from the housing a distance out of the housing and positioned below the inner water-guiding part, the inner water-guiding part and the outer water-guiding part defining a water guide passage configured to guide water inside the housing to the outside of the housing, and a water shield located outside the housing and covering a portion of the water guide passage outside the housing, a gap being defined between a lower part of the water shield and an outer surface of the housing. ### Claim 18 An electric control box for an air conditioner, comprising: a housing; a cooling fin running through the housing, the cooling fin having a part located inside the housing and another part located outside the housing; an inner water-guiding part extending from the housing a distance into the housing and positioned below the cooling fin; an outer water-guiding part extending from the housing a distance out of the housing and positioned below the inner water-guiding part, the inner water-guiding part and the outer water-guiding part defining a water guide passage configured to guide water inside the housing to the outside of the housing and wherein the housing defines an opening, and a lower edge defining the opening is bent towards the inside of the housing to form the inner water-guiding part, and a water shield located outside the housing and covering a portion of the water guide passage outside the housing, a gap being defined between a lower part of the water shield and an outer surface of the housing.
