The fin heat exchanger is directly placed in the collected condensate water, which may immerse the fins and reduce the heat exchange area, and may also cause the risk of freezing and cracking of the copper pipe. The water collecting tray on the market is easy to cause condensate water accumulation and bottom ice phenomenon. CONTENT OF THE UTILITY MODEL

[0025] The embodiment discloses a vertical heat pump all-in-one machine with heat exchanger fixing and condensate water collection, which mainly comprises a vertical shell 3, a water tank 1, a compressor 7, a water tank heat exchange microchannel, a fan assembly 5, a filter, a capillary, a fin heat exchanger 4, a water pan 6, a steam-water separator 71 and an electric control assembly 2 and the like structure, and the refrigerant passes through the water tank heat exchange microchannel, the filter, the capillary, the fin heat exchanger 4, the steam-water separator 71 and the gas inlet of the compressor 7 in sequence through the pipeline from the exhaust port of the compressor 7.

[0026] The water tank 1 is fixed at the lower part of the three-dimensional shell, and a base plate for isolating the water tank is installed at the upper part of the vertical shell. The water pan 6 is integrally welded by adopting a sheet metal process support, has no separated parts, is stable in structure and not prone to loosening and deformation, is easy to install, improves the installation efficiency, and has an upward turned-over plate 61 welded at the outer periphery of the water pan 6. A drain pipe 63 is installed on the turned-over plate 61, the inner circular bottom of the drain pipe 63 is tangent to the bottom of the water pan 6, and the water storage is effectively avoided. The condensate water generated by the system heat exchange flows into the lowest point drain port along the bottom plate, the drainage is timely and smooth, the water accumulation and icing are avoided, and the evaporator heat exchange efficiency is ensured. Two external legs 64 are welded on the outer side wall of the water pan 6, and the two external legs 64 are fixed on the base plate by screws. Instead of the previous mode of fixing the bottom plate of the water pan 6 to the base plate through fixing holes, the risk of water leakage of the fixing holes of the bottom plate of the water pan 6 is avoided. Two fixed plates 62 in the shape of Chinese character 'j' are welded in the bottom plate of the water pan 6, and the bottom of the fin heat exchanger 4 is fixed on the two fixed plates 62 by screw assemblies. The fin heat exchanger 4 is entirely within the range of the water pan 6. There is a certain distance between the fixed plate 62 and the bottom plate of the water pan 6, the height of the fixed plate 62 is higher than the vertex of the drain pipe 63, the fin heat exchanger 4 is elevated by the layered design, the condensate water is prevented from submerging the fins and freezing the copper pipe, the safety of the pipeline is ensured to avoid cracking, and the heat exchange efficiency is ensured. The steam-water separator 71 of the compressor 7 is also a part where external condensate water is prone to occur, and the steam-water separator 71 is suspended above the water pan 6.

[0027] Through the design of the vertical heat pump all-in-one machine with heat exchanger fixing and condensate water collection described in this embodiment, the steam-water separator 71 and the fin heat exchanger 4 are both above the water collecting tray 6, which can realize full coverage and no omission of condensate water collection. The bottom of the drain pipe 63 is tangent to the bottom plate of the water collecting tray 6, which effectively avoids water storage. The condensate water generated by the system heat exchange flows into the lowest point drain outlet along the bottom tray, and the drainage is timely and smooth, avoiding water accumulation and freezing, ensuring the evaporation heat exchange efficiency. Through the drain pipe 63, the condensate water can be concentrated and discharged, which is beneficial to improve the cleanliness and safety of the entire equipment area, and improve the service life of the heat pump water heater all-in-one machine.
