Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a detachable low-ambient-temperature anti-icing condensate collection and drainage device. Background Technology

[0002] Existing air conditioning heat pumps use a drip tray where condensate is directly discharged and spilled around without being collected. This easily leads to ice buildup in the drip tray at low temperatures. Condensate may be discharged directly into the unit's structure or accumulate into ice piles, damaging the fan blades or causing the ice to expand and compress the copper tubes of the finned heat exchanger, leading to tube rupture and refrigerant leakage, thus posing a safety hazard. Furthermore, since the outdoor unit is located outside the building, installation requires personnel to be on-site. In high-rise buildings, this can leave installers semi-suspended outside, making maintenance inconvenient. Therefore, we propose a detachable, low-temperature, anti-ice-accumulation condensate collection and drainage device. Summary of the Invention

[0003] The purpose of this utility model is to provide a detachable low-ambient-temperature anti-icing condensate collection and drainage device; addressing the problems of non-removable water collection tanks, complex manufacturing processes, and troublesome installation, as well as the technical issues of existing technologies that cannot centrally collect condensate and cause ice buildup, affecting normal machine use and posing a risk of damage.

[0016] According to the aforementioned detachable low-ambient-temperature anti-icing condensate collection and drainage device, the first disc, the second disc, the third disc, and the right-angle drain pipe elbow are connected by welding.

[0017] According to the aforementioned detachable low ambient temperature anti-icing condensate collection and drainage device, the heating element passes through the right-angle drain pipe elbow and the drain hole of the water collection tank, and is distributed along the second end of the bottom wall edge of the third plate of the water collection tank to the first end, then around to the other bottom wall edge of the first plate to the second end of the first plate, and distributed to the first end of the third plate, then extending to the second end of the third plate, then around to the second end of the second plate, extending to the first end, and then around to the second end of the second plate to form a back-and-forth distribution.

[0032] Reference Figures 1 to 5 This utility model provides a detachable low-ambient-temperature anti-icing condensate collection and drainage device, including a water receiving body 1; the water receiving body 1 is provided with multiple water collection troughs 2, with first water collection trough fixing screw holes 9 and second water collection trough fixing screw holes 16, and the water collection troughs 2 are connected to the bottom of the water receiving body 1 by bolts for easy assembly and disassembly; the heating element 3 is distributed in the water collection troughs 2, and is fixed to the bottom wall of the first plate 10, second plate 11 and third plate 13 of the water collection trough 2 by fixing clips 14 and passes through the water collection trough drainage hole 17 and right-angle drain pipe elbow 15;

[0033] The main body 1 of the water receiving tray includes a baffle plate 4, a first water receiving tray frame 5, a second water receiving tray frame 6, a third water receiving tray frame 7, and an oval drain hole 8.

[0034] A baffle plate 4 is provided on the main body of the water receiving tray. The two ends of the baffle plate 4 are welded to the first water receiving tray frame 5 and the second water receiving tray frame 6. The gap between the main body of the water receiving tray 1 and the baffle plate 4 is sealed with sealant. The baffle plate 4 and the frame of the main body of the water receiving tray form a U-shaped water baffle groove. Multiple elliptical drain holes 8 are opened inside the U-shaped water baffle groove, so that the condensate can quickly flow into the water collection groove 2 installed at the bottom of the main body of the water receiving tray through the elliptical drain holes 8.

[0035] The water collection tank 2 includes a first plate 10, a second plate 11, a third plate 13, an overflow notch slope 13, a fixing clamp 14, a right-angle drain pipe elbow 15, a second water collection tank fixing screw hole 16, and a water collection tank drain hole 17.

[0036] The water collection trough is welded from the second end of the first plate 10 to the first end of the third plate 12, and the second end of the second plate 11 is welded to the second end of the third plate 12; a fixing clamp 14 is welded to one side of the bottom wall of the first plate 10, the second plate 11, and the third plate 12; a water collection trough drainage hole 17 is opened at the lowest point of the second end of the third plate 12; a right-angle drain pipe elbow 15 is welded to the bottom of the water collection trough drainage hole 17;

[0037] Heating elements are installed on the bottom walls of the first plate 10, the second plate 11, and the third plate 12 of the water collection tank;

[0038] The heating element 3 passes through the right-angle drain pipe elbow 15 and the water collection tank drain hole 17, and is distributed along the second end of the bottom wall edge of the third plate 12 of the water collection tank to the first end, then around to the other bottom wall edge of the first end of the first plate 10 to the second end of the first plate 10, and then distributed to the first end of the third plate 12, and then extended to the second end of the third plate 12, then around to the second end of the second plate 11 and extended to the first end, and then around back to the second end of the second plate 11 to form a back-and-forth distribution.

The condensate in the third plate 12 then flows along the lowest point of its inner bottom wall to the drain hole 17 in the water collection trough at the lowest point of the third plate 12, and is discharged through a right-angle drain pipe elbow 15. When the ambient temperature is low, the heating element 3 in the water collection trough 2 heats the condensate, preventing it from freezing and accumulating, thus allowing it to drain quickly. When the drain is blocked due to some factor, preventing cold water from draining, the water collection trough has an overflow notch sloping surface 13 on the side wall of the third plate 12. When the accumulated cold water level exceeds the overflow notch sloping surface 13, it can drain through the overflow notch sloping surface 13, preventing ice buildup.

[0040] Working principle: This technical solution combines the main body 1 of the water receiving tray, the water collection tank 2, and the heating element to form a detachable low-ambient-temperature anti-icing condensate collection and drainage device. The heating element 3 is fixed in the water collection tank 3 by a single-sided welded fixing clamp 14, which is convenient for disassembly and installation and easy for later maintenance. The water collection tank 2 is fixed upward to the fixing screw hole 16 of the second water collection tank by bolts passing through it and locking it. This can make the water collection tank tightly and firmly fixed to the bottom of the main body 1 of the water receiving tray. At the same time, the water collection tank can be removed by loosening and tightening the fixing bolts. The installation is convenient.
