Water repellent fan leaf structure of outdoor fan of window air conditioner

Abstract

The invention relates to a window-type air conditioner, in particular to an outdoor fan water repelling fan blade structure of the window-type air conditioner, and solves the problems that the outdoor fan of the prior window-type air conditioner repels water by fan blades and connecting rings, has small water taking amount and causes that a water receiving tray accumulates water, condensed water exhausted by the fan is reduced, a condenser has low heat exchange rate and the efficiency of the air conditioner is declined. The outdoor fan water repelling fan blade structure consists of a hub which is provided with a flattened axial hole in the center and can be screwed with a motor pivot of the fan, a plurality of fan blades which are radially injected or welded on the periphery of the hub and provided with torsional angles and connecting rings; the outdoor fan water repelling fan blade structure is characterized in that: a folded angle water repelling part is injected or folded on the end part of each fan blade. When the fan blades rotate, the outdoor fan water repelling fan blade structure of the window-type air conditioner can bring more condensed water from the water receiving tray and evenly scatter the condensed water to the condenser in order that a heat exchange rate of the condenser is improved and an efficiency of the air conditioner is raised subsequently.

Description

technical field [0001] The invention relates to a window-type air conditioner, in particular to a water-draining blade structure of an outdoor fan of the window-type air conditioner. Background technique [0002] Existing window air conditioners such as figure 1 , 2 As shown in , 6, the outer casing 2 is formed; the chassis 3 for installing parts; the panel 4 arranged on the inner side of the chassis; the lower side of the panel 4 is formed with an air inlet 4a, and the upper side has an exhaust port 4b; the inner side of the panel 4 The evaporator 6 is arranged in sequence; the indoor fan 7; the air guide 8 (8a, 8b, 8c); the fan motor 14; the compressor 16; , the outer panel of the exhaust port; the chassis 3 is designed with a water tray 20; the connecting ring 24 of the outdoor fan 11 is rotated and installed in the water tray 20. When the air conditioner is running, the condenser 12 will be compressed by the refrigerant The heat needs to be released quickly, otherwise...

AI Technical Summary

Problems solved by technology

The domestic invention patent, the patent number is 03144189.2, discloses a solution to the above problems, which is to use the fan blade 23 of the outdoor fan 11 and its connecting ring 24 to lift up the condensed water in the water receiving tray 20 and guide it through the guide groove Pass through the condenser 12 to discharge the air conditioner, which not only avoids the accumulation and overflow of condensed water, but also improves the heat exchange efficiency of the condenser 12, thereby also improving the efficiency of the air conditioner. Not big, the cross section of the connecting ring 24 is very small, so there is still little condensed water brought out from the water tray 20, so that the evaporator 6 and the condenser 12 cannot perform heat exchange smoothly, the water tray accumulates water, and the efficiency of the air conditioner cannot be improved The problem
