The invention designs a circular outdoor cover of an air conditioner. The nozzle structure is inserted through a wall hole of the wall body 90, and the housing assembly 100 is disposed at an end of the nozzle structure located outdoors. Fresh air enters from a second grid plate 61 and a fresh air side transverse rib (second connecting rib 62) of fresh air side grids (second ventilating grid 60) on two sides of a fresh air chamber outer joint (second outdoor joint 20) of the circular chamber outer cover and enters into an indoor fresh air port (fresh air port 212) along a fresh air pipe (second ventilating pipe 32), dirty air is exhausted along an exhaust pipe (first ventilating pipe 31) and is exhausted from an exhaust chamber outer joint (first outdoor joint 10), and a first grid plate 51 and a vertical rib (first connecting rib 52) of a rain-proof covered dirty air exhaust grid (first ventilating grid 50) are exhausted. The housing assembly is sealed to the wall 90 by a fresh air duct sealing rubber ring (first sealing ring 70) and is fixed by glass cement.
The circular chamber outer cover assembly consists of a rain-proof cover, an exhaust chamber outer joint, a fresh air pipe sealing rubber ring and an exhaust pipe sealing rubber ring.
The pipe connecting component consists of a heat-insulating sleeve, a fresh air pipe, an exhaust pipe, a support frame (support component 221), an indoor joint, a foam joint and an exhaust pipe sealing rubber ring.
The principle that the circular chamber outer cover prevents the short circuit of fresh air and dirty air is as follows:
dirty wind in the exhaust pipe is discharged from the room, and the wind speed is very big, and the new trend in the new trend pipe is introduced from the open air, and the wind speed is less, has the pressure differential, scurries the wind easily. The rain-proof cover cap is matched with the outer joint of the exhaust chamber, and dirty wind is exhausted from the lower side in front of the rain-proof cover cap through the exhaust pipe. An exhaust pipe sealing rubber ring is arranged between the exhaust pipe and the outer joint of the exhaust chamber, so that fresh air in the fresh air pipe is prevented from entering the exhaust pipe.
The fresh air pipe and the fresh air chamber are assembled through outer joints, and a fresh air pipe sealing rubber ring is assembled in the middle of the fresh air pipe sealing rubber ring, so that the fresh air pipe is prevented from being blown into the outside air of the fresh air pipe. In the circular chamber outer cover component, the fresh air channel and the air exhaust channel are skillfully separated by the air exhaust pipe joint. The fresh air is towards the wall body, the fresh air chamber outer joint is introduced from back to front, the exhaust air is discharged from the rain cover to the lower side in the front, and no interference exists in the directions of the two air streams.
The invention designs the circular outdoor cover assembly, thereby solving the hidden danger problem that mice and insects enter the room and the problems of short circuit of fresh air and exhaust air, backflow of rainwater and inconvenience in after-sale installation.
Insect prevention and rat prevention principle:
as shown in fig. 2 and 3, the louver grilles (second grill plates 61) and the transverse bars (second connecting bars 62) are arranged on two sides of the fresh air chamber external joint, and the matching structure of the grilles and the transverse bars can effectively prevent rats and insects from entering.
As shown in fig. 3, the rain cover has a louver grille (first grille plate 51) and vertical ribs (first connecting ribs 52), and the matching structure of the grille and the vertical ribs can effectively prevent rats and insects from entering.
Rainwater backflow prevention principle:
as shown in figure 2, the louver grilles are angled backwards, no gap can be formed between the grilles when viewed from the side view, but a gap of 5mm to 25mm is formed between the grilles when viewed from the back to the front, and the grilles with the structure can prevent rainwater from flowing into the indoor outer cover without influencing fresh air guiding. Rainwater flows to the outer joint surface of the fresh air chamber and can flow down along the circular cambered surface structure, so that rainwater accumulation cannot be caused, and hidden troubles of inflow into the outer cover of the chamber are avoided. As shown in FIG. 4, even if there is condensed water or rainwater inside the outdoor enclosure, the condensed water or rainwater can be discharged along the rainwater guide arc structure (guide protrusion 21) of the fresh air chamber external joint.
As shown in figure 3, the louver grilles are downwards angled, gaps can not be formed between the grilles when viewed from the front view, but gaps of 5mm to 25mm are formed between the grilles when viewed from the bottom to the top, and the grilles with the structure can prevent rainwater from flowing into the indoor housing without influencing the sewage discharge wind. Meanwhile, the outer joint of the exhaust chamber has a certain downward taper forward, so that rainwater can flow outdoors even if part of the rainwater enters the outer joint of the exhaust chamber.
Procedure from indoor installation:
the invention can be installed only from indoor, does not need to install outdoors, has guaranteed the security of the installation master after sale. The circular chamber outer cover assembly is assembled on the pipe connecting assembly indoors, then the assembled assembly is poked out through a wall hole, the second sealing rubber ring retaining ring (the second groove wall 712) cannot expose the outer side of the wall body, the first sealing rubber ring retaining ring (the first groove wall 711) is guaranteed to be not exposed out of the outer side of the wall body as far as possible, and therefore the sealing rubber ring retaining ring can play a role in sealing the wall body. An installer can inject glass cement into the indoor gap to effectively fix the pipe connecting assembly.
From the above description, it can be seen that the above-described embodiments of the present invention achieve the following technical effects:
(1) the problem that insects and mice easily enter the room is solved;
(2) the problem of short circuit of fresh air and exhaust air is solved;
(3) the problem of rainwater backflow is solved;
(4) the problem of the inconvenient installation of outdoor installation new trend rain-proof cover of after sale is solved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
