Detailed Description

For a better understanding of the present invention, embodiments of the present invention are explained in detail below with reference to fig. 1 to 3.

It should be noted that the "inside and outside" directions described herein refer to the inside and outside directions of the box, and the drawings are a cross sectional plan view of one side surface of the box, and the inside is the lower side and the outside is the upper side as viewed in the drawings.

The positive pressure section inward opening door assembly of the air conditioning unit comprises a box body (only one surface of the box body with an inward opening door is shown in the attached drawing) and an inward opening door 1, wherein one side of the inward opening door is hinged to the box body through a hinge. A door lock 2 is arranged between the inward opening door 1 and the cabinet, and the door lock 2 is preferably a lock body mounted on a cabinet plate 3 as shown in the figure. The lock handle is positioned outside the box body. A door handle 17 is provided on the outside of the in-opening door.

The box body panel 3 around the in-opening door 1 includes an inner panel 31, an outer panel 32, and a foaming material 33 filled between the inner panel 31 and the outer panel 32, and the foaming material is preferably a urethane foam (the same applies hereinafter). An aluminum via 4 is connected to the end of the case plate 3, and the aluminum via 4 is not in contact with the inner plate 31. The in-opening door 1 includes an inner door panel 11, an outer door panel 12, a heat insulating block 13, and a foaming material 14 filled between the inner door panel 11 and the outer door panel 12, the inner door panel 11 and the outer door panel 12 do not contact, and the heat insulating block 13 is disposed between the end of the outer door panel 12 and the inner door panel 11. Other heat insulating materials such as foam blocks, wood blocks, or rubber blocks can be used for the heat insulating blocks 13.

The left side and the right side of the inner side of the inward opening door 1 are respectively provided with a boss 15, the inner side of the box body plate 3 is provided with a groove 34 corresponding to the boss 15, and the boss 15 is provided with a sealing strip 16.

Specifically, the inner door panel 11 and the outer door panel 12 are not in contact with each other as shown in the accompanying drawings, and as shown in fig. 1 and fig. 2, a horizontal section ii 121 extends from the end of the outer door panel 12 to the center of the inward opening door, horizontal sections i 111 extending from the center of the inward opening door 1 are arranged at two sides of the inner door panel 11, and the horizontal sections i 111 are located at the side surfaces of the outer door panel 12. Although this design is relatively easy to assemble, when the inner door is subjected to internal pressure, the joint between the inner door panel 11 and the outer door panel 12 is likely to crack. For this purpose, as shown in fig. 3, horizontal sections i 111 extending toward the center of the inward opening door 1 are provided at both sides of the inner door panel 11, and horizontal sections ii 121 located inside the horizontal sections i 111 are provided at both sides of the outer door panel 12, and the horizontal sections i 111 can provide a drawing action to the horizontal sections ii 121 to prevent the door panel from being cracked. Similarly, as shown in fig. 1 and fig. 2, the structures of the horizontal section iii 311 and the horizontal section iv 321 are relatively easy to assemble, but are easy to crack, so the inner plate 31 and the outer plate 32 of the present invention are also designed to be drawn into each other, specifically, the horizontal section iii 311 is respectively disposed on both sides of the end of the inner plate 31, and the horizontal section iv 321 located inside the horizontal section iii 311 is respectively disposed on both sides of the end of the outer plate 32. In order to prevent heat transfer between the inner and outer panels, the outer panel is wrapped at its ends with insulating mats 6 as shown in fig. 3. Similarly, the end of the horizontal section I111 can be wrapped by a heat insulation pad.

In order to reinforce the structural strength of the in-opening door, two reinforcing plates 5 are crossed in the foaming material 14 of the in-opening door 1. The two reinforcing plates 5 can be fixed directly inside the foamed material 14. The reinforcing plate 5 may be fixed at both ends thereof to the heat insulating blocks 13 (when the heat insulating blocks are made of wood or other hard heat insulating materials). Of course, the reinforcing plate 5 may also be of an X-shaped integral structure.

It should be noted that although the present specification describes embodiments, not every embodiment includes only a single technical solution, and such description of the specification is only for clarity, and those skilled in the art should take the specification as a whole, and the technical solutions in the embodiments may be appropriately combined to form other embodiments that can be understood by those skilled in the art. For example, the material of the novel inner door panel, outer door panel, inner panel and outer panel is not limited to color-coated sheet, and other sheet materials such as galvanized sheet or stainless steel sheet may be used.
