Detailed Description

The invention will be further described with reference to the following examples.

The splash-proof ventilation window on the load box is shown in fig. 1 and comprises a rectangular frame 1, wherein a blade group 2 is fixed in the frame 1, the blade group 2 is shown in fig. 2, the blade group 2 is formed by vertically arranging a plurality of blades 21 with the same structure, and the splash-proof ventilation window is only ventilated through the blades 21.

The cross-sectional structure of each blade 21 is as shown in fig. 3, and comprises a base plate a, a water baffle B, a blocking plate C, a water return groove D and a connecting plate E which are connected with brackets on the left side and the right side of the frame from bottom to top. The substrate A is arranged obliquely, and the inclination angle of the substrate A with the horizontal plane is 134.4 degrees. The water return tank D is composed of two vertical plates D2, D3 and a top plate D1, the vertical plates D2, D3 and the top plate D1 are also connected with the supports on the left side and the right side of the frame, the top plate D1 is horizontally arranged, the two vertical plates D3 and D2 are respectively fixed on two exposed sides of the top plate D1, and a tank body with a downward opening is formed. The vertical plate D3 is far away from the window than the vertical plate D2 and is positioned behind the vertical plate D2. The vertical plate D3 is fixedly connected with the base plate a, so that the water return tank D is inverted on the base plate a, and the vertical plate D2 is hung above the base plate a.

The water baffle B is located between the water returning groove D and the outside of the window to block in front of the vertical plate D2, and the water baffle B is fixed on the bottom of the base plate a of the upper stage blade through the joint plate E. Wherein the water baffle plates B are also arranged obliquely at an angle of 51.4 DEG to the horizontal, and the connector tiles E are arranged vertically so that the faces of the connector tiles E facing the outside of the window do not have sharp acute angles. Furthermore, the connector plates E in each blade are positioned in line so that the outer sides of the blade sets are flush.

Referring to fig. 3, in the blade of this stage, a line connecting the bottom end of the vertical plate D2 and the bottom end of the base plate a is referred to as L1, the bottom end of the water guard B crosses the line L1, and an opening is left between the bottom end of the vertical plate D2 and the water guard B, and these openings are used for ventilation.

The blocking plate C is fixed on the rear side of the water guard B and is located between the water guard B and the vertical plate D2. The plugging plate C is arranged obliquely with an angle of inclination of 149.1 ° to the horizontal. The point of intersection of the extension line of the water guard B and the base plate a is referred to as point O, the extension line of point O and the bottom end of the vertical plate D2 is referred to as L2, and the top end of the blocking plate C reaches or even goes beyond the extension line L2, so that water droplets splashed between the water guard B and the vertical plate D2 can be almost completely intercepted. It should be noted that an opening is required to be left between the blocking plate C and the vertical plate D2 for ventilation.

In rainy days, if raindrops fall on the water baffle B, the raindrops can flow off along the surface of the water baffle B; if raindrops fall on the substrate a, the raindrops may splash on the substrate a, and a part of the splashed raindrops may be injected into the ventilation window from the opening between the water baffle B and the substrate a, and the splashed raindrops either enter the region S1 and are blocked back by the water returning groove D, so that the raindrops flow out along the groove wall of the water returning groove D and the surface of the substrate a, or enter the region S3 and are blocked back by the blocking plate C, so that the raindrops flow out along the water baffle B and the substrate a. Since the splashed raindrops cannot enter the area S2, the raindrops cannot pass through the ventilation window and enter the load box, and complete interception of the raindrops is basically achieved.

When the load box works, the resistor disc inside the load box generates a large amount of heat, so that air is heated, and the air in the load box is heated and expanded. In the state where the suction fan of the loadbox is not activated, the expanded air is discharged to the outside through the ventilation window, and the air flow path thereof is as shown in fig. 5. When the load box is overheated, the load box starts the exhaust fan to exhaust air, so that hot air is exhausted to the outside, the outside air is supplemented into the load box through the ventilation window at the moment, and the air flow channel of the load box is opposite to the air flow direction in the graph 5.

Since the structure of the exhaust fan on the load box and the position thereof belong to the prior art, the detailed description thereof is omitted herein.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present application, and not for limiting the protection scope of the present application, and although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present application without departing from the spirit and scope of the technical solutions of the present application.
