Air conditioner outdoor unit and liquid level control method of condensate collection device thereof, and air conditioner

Abstract

The invention discloses an air conditioner outdoor unit, a liquid level control method of a condensate water collecting device of the air conditioner outdoor unit, and an air conditioner. The air conditioner outdoor unit comprises an outdoor unit shell (1), an outdoor unit heat exchanger (2) and the condensate water collecting device (3) arranged on the top part of the outdoor unit shell (1). A filter (4) is arranged on an opening part on the top part of the condensate water collecting device (3); a level indicator (5) is arranged in the condensate water collecting device (3); a condensate water conveying pipe (6) for conveying condensate water to the outdoor unit heat exchanger (2) is arranged on the bottom part of the condensate water collecting device (3); a flow control valve (7) is arranged on the conveying pipe (6); and the air conditioner outdoor unit adjusts the opening of the flow control valve (7) according to a liquid level, detected by the level indicator (5), in the condensate water collecting device (3). According to the air conditioner outdoor unit provided by the invention, the problem that in the prior art, the self-cleaning requirement of the air conditioner outdoor unit cannot be well met since the condensate water volume on the outdoor side is not stable can be solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a liquid level control method for an outdoor unit of an air conditioner and a condensed water collection device thereof, and an air conditioner. Background technique [0002] When installing the outdoor unit of the air conditioner, the exposed side of the heat exchanger is generally close to the wall and the distance is small. Long-term use of the air conditioner will cause a lot of dust and debris to condense on the fins of the heat exchanger, which will affect the heat transfer of the heat exchanger and reduce the efficiency of the air conditioner. The performance of the whole machine and shorten the service life of the air conditioner. [0003] In addition, in some areas with more rainfall in summer, the current treatment of condensed water generally adopts the method of discharging anywhere, and some will consider discharging it outdoors to exchange heat with the out...
