Wherein, the door panel 1 is an installation base, on which a ventilation louver hole opening downward is arranged; the door inner lining plate 3 is an installation support, and the door inner lining plate 3 and the door panel 1 are sealed together;

The dust-proof net assembly 5 is fixedly connected with the door lining plate 3, and the dust-proof net assembly 5 is provided with ventilation louver holes with upward openings, and the dust-proof net assembly 5 and the door lining plate 3 Seal together.

Further, the dust-proof net assembly 5 specifically includes: a ventilation plate 6, a dust-proof net 7, and a pressing plate 8;

Wherein, the dust-proof net 7 is plugged in the pressing plate 8, and the pressing plate 8 and the ventilation plate 6 are fixed together.

Further, the pressure plate 8 and the ventilation plate 6 are fixed together by screws.

Further, the dust-proof net (7) is made of sponge material.

Further, the lowermost row of louver holes of the door panel 1 is lower than the installation joint surface of the door lining panel 3 and the door panel 1 .

Further, the dustproof screen assembly 5 and the door lining plate 3 are fixed together by screws.

Further, the door lining panel 3 and the door panel 1 are sealed together by a sealing strip 2 .

Further, the dust filter assembly 5 and the door inner liner 3 are sealed together by a sealing strip 4 .

In summary, the utility model improves a ventilation door panel. The louver hole opening of the door panel 1 of the utility model is downward, and the louver hole opening of the dust-proof net assembly 5 is upward. Cooperate to meet the sealing requirements of IP55, the external spray water cannot reach the inside of the cabinet, and no water will remain in the door panel, and on the basis of achieving sealing, the ventilation requirements inside and outside the cabinet are well realized.

Detailed ways

The ventilation door panel described in the utility model will be described in detail below in conjunction with the accompanying drawings.

As shown in Fig. 1 and Fig. 2, Fig. 1 and Fig. 2 are the overall schematic diagrams of the outside and inside of the ventilation door panel respectively.

As shown in FIG. 3 , FIG. 3 is a schematic structural diagram of the ventilation door panel. The ventilation door panel mainly includes: a door panel 1 , a sealing strip 2 , a door lining 3 , a sealing strip 4 , and a dustproof net assembly 5 .

Wherein, the door panel 1 is an installation base, on which a ventilation louver hole is opened, and the opening of the louver hole is downward; the door lining plate 3 is an installation support, and a sealing strip 2 is installed between it and the door panel 1 to realize sealing; of course, Those of ordinary skill in the art should know that the door liner 3 and the door panel 1 can also be sealed in other ways, as long as the sealing effect is achieved.

The dust-proof net assembly 5 and the door liner 3 are fixedly connected together. During the specific implementation of the present utility model, the dust-proof net assembly 5 and the door liner 3 can be fastened and connected by screws. The opening of the ventilation louver hole of the dust-proof net assembly 5 is upward, and a sealing strip 4 is installed between the dust-proof net assembly 5 and the door inner liner 3 to realize sealing. Of course, those of ordinary skill in the art should know that the seal between the dustproof component 5 and the door liner 3 can also be achieved in other ways, as long as the sealing effect is achieved.

Fig. 4 is a sectional view of the sealing structure of the ventilation door panel, Fig. 5 is an enlarged detail view of part I in the sectional view of the sealing structure of the ventilation door panel shown in Fig. 4 , and Fig. 6 is an enlarged detail view of part II in the enlarged detail view shown in Fig. 5 . From Figure 4 to Figure 6, it can be seen that on the outside of the cabinet, the opening of the louver hole of door panel 1 is downward; on the inside of the cabinet, the opening of the louver hole of dust filter assembly 5 is upward; Since the opening of the louver hole of the dust-proof net assembly 5 is upward, water droplets must flow back to the inside of the door panel instead of entering the inside of the cabinet.

Moreover, the lowermost row of louver holes of the door panel 1 is slightly lower than the installation joint surface of the door lining panel 3 and the door panel 1 . In this way, it can be ensured that the accumulated water inside the door panel can flow out, so that no accumulated water can be realized.

As shown in FIG. 7 , FIG. 7 is a schematic structural diagram of the dust-proof net assembly 5 . The dust-proof net assembly mainly includes: a ventilation plate 6 , a dust-proof net 7 , and a pressure plate 8 .

Wherein, the dust-proof net 7 is plugged in the pressing plate 8, and the pressing plate 8 and the ventilation plate 6 are affixed together. In the specific implementation process of the present utility model, the pressing plate 8 and the ventilation plate 6 can be fastened and connected by screws; Net 7 is usually a sponge material, and the sponge material can achieve the effects of dustproof and moisture absorption.

In summary, the ventilation door panel described in the present utility model has the opening of the louver hole of the door panel 1 downward, and the opening of the louver hole of the dust-proof net assembly 5 is upward, and through cooperation with the sealing strip and the sponge dust-proof net, IP55 is achieved. Sealing requirements, external spray water cannot reach the inside of the cabinet, and no water will remain in the door panel, and on the basis of achieving sealing, the ventilation requirements inside and outside the cabinet are well realized.
