The electric control box is mainly used to control the operation of electrical equipment and has functions such as power distribution, control, measurement and protection. The outdoor condenser is an indispensable and important component in precision air conditioning, and the electric control box on the condenser outdoor unit is an even more important component. The electric control box is equipped with switches and fan drives, which are electrical components that cannot touch water, so the waterproof function of the electric control box has become a top priority.

[0003] At present, most of the electric control boxes on the market have relatively simple structures and functions, and are usually produced by simply spraying paint on cold-rolled plates. After long-term use in the external environment, the paint on the surface of the electric control box is prone to paint peeling and corrosion after being exposed to wind, rain and sun. This may cause water to enter the electric control box, resulting in poor waterproof performance and serious safety hazards, causing the practicality of the electric control box to be reduced. Therefore, we propose a waterproof electric control box structure for an air-conditioner outdoor unit to solve the above problems. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] Reference Figure 1-5 The top of the box body 1 is provided with a sealing groove matched with the sealing block 7, and one side of the sealing block 7 is symmetrically provided with two slots. The front side of the box body 1 is symmetrically provided with a positioning assembly connected with the adjacent slots. Card plates 9 are provided on both sides of the sealing plate 3, and the adjacent side walls of the two card plates 9 are provided with card slots matched with the side walls of the sealing plate 3. The two sides of the two card plates 9 away from each other are fixedly connected with the adjacent inner wall of the box body 1. A plurality of electrical components 14 are fixedly installed on the inner wall of the rear side of the box body 1, and a plurality of ventilation holes 5 are penetrated through the inner walls of the two sides of the box body 1 in a linear array. Specifically, the sealing block 7 and the sealing plate 3 are conveniently positioned by operating the positioning assembly, so that personnel can conveniently open and close the electric control box to maintain the electrical components 14, thereby improving the convenience and practicality of the operation of the electric control box.

[0025] Furthermore, the positioning assembly includes a connecting plate 10 arranged on the front side of the box body 1, and the connecting plate 10 is U-shaped. The side walls at both ends of the connecting plate 10 are fixedly connected to the front surface of the box body 1. A pull rod 11 is provided inside the connecting plate 10. One end of the pull rod 11 passes through the front side wall of the box body 1 and is plugged into the slot, and the other end of the pull rod 11 passes through the side wall of the connecting plate 10 and is fixedly installed with a pull block 12. Specifically, through the provision of the pull block 12, it is convenient for a person to hold the pull block 12 and pull the pull rod 11 to move, so as to achieve the effect of making the pull rod 11 convenient for quickly positioning the sealing block 7 and the sealing plate 3.

[0026] Furthermore, the positioning assembly also includes a spring 13 arranged on one side of the connecting plate 10, the interior of the spring 13 is nested with the exterior of the pull rod 11, and the two ends of the spring 13 are respectively fixedly connected to the pull block 12 and the adjacent side walls of the connecting plate 10. Specifically, through the setting of the spring 13, a person can hold the pull block 12 to pull the pull rod 11 to move one end of it out of the slot. At this time, the pull block 12 stretches the spring 13 to release the positioning of the sealing block 7. By holding the handle 6 and pulling it upward, the sealing block 7 and the sealing plate 3 can be pulled out, which is convenient for personnel to maintain components. The two sides of the sealing plate 3 are symmetrically slid into the two card slots through the sealing groove, so that the bottom of the sealing plate 3 fits with the top of the sealing gasket 8, and then the pull block 12 is loosened to make the spring 13 lose its tension and elastically recover to pull the pull block 12 back to its original position. The pull block 12 then drives the pull rod 11 back to its original position and inserts one end of it into the slot to position the sealing block 7, thereby completing the positioning of the sealing plate 3, achieving the effect of facilitating the opening and closing of the sealing plate 3 and facilitating personnel to maintain and replace the electrical components 14. At the same time, the sealing plate 3, the sealing block 7 and the sealing gasket 8 achieve good waterproof performance and a simple appearance, thereby improving the practicality of the electric control box.

[0027] Furthermore, a mounting groove matched with the bottom of the sealing plate 3 is opened on one side of the bottom of the box body 1, and a sealing gasket 8 is fixedly installed in the mounting groove. Specifically, through the setting of the sealing gasket 8, when the sealing plate 3 is lowered into the mounting groove, the bottom of the sealing plate 3 will fit with the sealing gasket 8, thereby achieving a sealing effect on the bottom of the box body 1, preventing rainwater from flowing from the bottom of the box body 1 to the inside of the box body 1, wherein the box body 1, the sealing plate 3 and the sealing block 7 are all galvanized by adding outdoor powder sprayed on the galvanized sheet, so that the paint will not fall off and the corrosion will not be achieved after a long period of wind and rain.

[0028] Furthermore, a plurality of water guide grooves 4 are provided in a linear array on the top of the box body 1. Specifically, through the provision of the water guide grooves 4, rainwater falls on the top of the box body 1 when it rains, and then the rainwater drops flow through the water guide grooves 4 through the plurality of water guide grooves 4. Since the water guide grooves 4 are at an inclined angle, the rainwater naturally slides down the grooves due to the influence of gravity, thereby preventing the rainwater from penetrating into the interior of the box body 1 to damage components, thereby greatly increasing the waterproof performance of the box.

[0029] Furthermore, a handle 6 is fixedly installed in the middle of the top of the sealing block 7. Specifically, through the setting of the handle 6, it is convenient for a person to hold the handle 6 and pull up the sealing block 7 to drive the sealing plate 3 to be pulled out and open the inside of the box body 1 to operate the electrical components 14.

[0030] In summary:

[0031] By holding the pull block 12 and pulling the pull rod 11 to move one end of it out of the slot, the pull block 12 stretches the spring 13 to release the positioning of the sealing block 7. By holding the handle 6 and pulling it upward, the sealing block 7 and the sealing plate 3 can be pulled out for personnel to maintain the components. During installation, the two sides of the sealing plate 3 are symmetrical with the two card slots through the sealing groove and slide in, so that the bottom of the sealing plate 3 fits with the top of the sealing gasket 8. Then, the pull block 12 is released to make the spring 13 lose its tension and elastically recover to pull the pull block 12 back. The pull block 12 then drives the pull rod 11 to return and insert one end of it into the slot to position the sealing block 7, thereby completing the positioning of the sealing plate 3, achieving the effect of facilitating the opening and closing of the sealing plate 3 and facilitating personnel to maintain and replace electrical components 14. At the same time, the sealing plate 3, the sealing block 7 and the sealing gasket 8 achieve good waterproof performance and simple appearance, thereby improving the practicality of the electric control box.
