[0021] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but they are not intended to limit the present invention.

[0022] See also Figures 1 to 5 As shown, according to an embodiment of the present invention, an electric control box is provided, which includes a panel 10 and a box body 20, the panel 10 is fixed on the box body 20, the panel 10 and the box body 20 are sealed by a sealing strip 30, a first reinforcing rib 21 is arranged on the box body 20, the first reinforcing rib 21 forms a water retaining groove 211, the opening of the water retaining groove 211 is arranged toward the gap 40 between the panel 10 and the box body 20, and the first reinforcing rib 21 is located between the sealing strip 30 and the gap 40.

[0023] A first reinforcing rib 21 structure is designed on the body of the electric control box. The first reinforcing rib 21 also forms a water retaining groove 211. When water seeps in from the gap between the body and the panel, it will be blocked on the outside of the first reinforcing rib 21 by the water retaining groove 211, thereby effectively preventing water or other liquids from contacting the sealing strip, thereby preventing the sealing strip from aging. The sealing strip remains effective for a long time, and can ensure the stable operation of the electric control box for a long time.

[0024] The surface of the box body 20 protrudes to form a first reinforcing rib 21, the side wall of the water retaining groove 211 is connected to the surface of the box body 20, and the side wall of the water retaining groove 211 is connected to the gap 40. Figure 1 and Figure 2 The first reinforcing rib 21 is formed by directly protruding from the surface of the box body 20. The first reinforcing rib 21 can be a part of the box body 20 or an independent structure. The first reinforcing rib 21 is L-shaped as a whole, and a water retaining groove 211 is formed on the structure. The side wall of the water retaining groove 211 is connected to the gap 40. This structure allows water or other liquids that penetrate into the gap to enter the water retaining groove 211 along the side wall, and will not pass over the first reinforcing rib 21 and contact the sealing strip. This structure improves the anti-seepage effect.

[0025] The box body 20 is provided with a second reinforcing rib 22, and a sealing strip 30 is installed between the second reinforcing rib 22 and the panel 10, and the sealing strip 30 is respectively sealed and connected with the second reinforcing rib 22 and the panel 10. The electric control box of the present invention uses a double-layer reinforcing rib structure, and the second reinforcing rib 22 is located on the inner side of the electric control box relative to the first reinforcing rib 21, and the second reinforcing rib 22 is farther from the gap. The second reinforcing rib 22 and the first reinforcing rib 21 can increase the overall structural strength of the electric control box, and the double-layer reinforcing rib structure can also achieve double-layer sealing, which has the effect of one object with multiple uses.

[0026] In order to further improve the structural coordination and sealing, the panel 10 has a first groove 11 and a second groove 12 on the side facing the box body 20, the first reinforcing rib 21 is located in the first groove 11, the second reinforcing rib 22 is located in the second groove 12, and the sealing strip 30 is located in the second groove 12. The coordination of the first reinforcing rib 21 and the first groove 11 can effectively prevent water or other liquids from penetrating into the second groove. The coordination of the second reinforcing rib 22, the sealing strip 30 and the second groove 12 can improve the sealing of the sealing strip and improve the stability of the electric control box.

[0027] The first groove 11 and the second groove are both annular grooves formed on the panel 10 . The sealing strip 30 is an annular strip structure. Correspondingly, the first reinforcing rib 21 and the second reinforcing rib 22 are protruding annular ribs.

[0028] like Figure 3As shown, the first groove 11 and the second groove 12 are separated by a metal rib 13, and a magnetic attraction component 50 corresponding to the position of the metal rib 13 is provided on the box body 20. In this embodiment, the first groove 11 and the second groove 12 are arranged adjacent to each other, and the metal rib 13 is between the first groove 11 and the second groove 12, and the two sides of the metal rib 13 form a partial side wall structure of the first groove 11 and the second groove 12. The metal rib 13 is firmly attracted by the magnetic attraction component 50, so that the panel and the box body are fixed.

[0029] In this embodiment, the magnetic attraction component 50 is an electromagnet in the electric control box that can be energized. After the electromagnet is energized, the metal ribs are firmly attracted by the electromagnet, thereby achieving a fixed seal between the panel and the box body.

[0030] In order to further simplify and coordinate the structure, the magnetic component 50 is located between the first reinforcing rib 21 and the second reinforcing rib 22. The magnetic component 50 corresponds to the metal rib 13. After the magnetic component 50 attracts the panel, the first reinforcing rib 21 and the second reinforcing rib 22 also enter the corresponding groove structure at the same time.

[0031] like Figure 4 As shown, a switch 23 is provided on the box 20, and the switch 23 is used to control the power on and off of the electromagnet. The power needs to be turned off manually before opening the panel, which can reduce the risk of electric shock caused by live operation by maintenance personnel. A terminal interface 24 is provided on the box 20, and the terminal interface 24 is the interface for the electric control box to connect to the outside.

[0032] The present invention provides an embodiment of an air-conditioning unit, and the air-conditioning unit comprises the electric control box of the above embodiment.
