Water beating structure and window type air conditioner using same

Abstract

The invention discloses a water beating structure, which comprises a lower air inlet arranged on a base plate and a centrifugal fan arranged on the lower air inlet. A water storage tank is formed corresponding to the bottom of the centrifugal fan on the base plate. A blade of the centrifugal fan is formed with an arc-shaped convex edge or a groove which extends up from top down. The convex edge or the groove extends towards the center of the centrifugal fan. Meanwhile, the invention also discloses a window type air conditioner using the water beating structure. The water beating action at the outdoor side of the window type air conditioner is realized by using self suction force of the fan. The water storage tank is arranged on an upper air inlet of the base plate. The blade of the fan is provided with the convex edge or the groove. The condensed water is stirred up by the blade and a wheel disc at an inlet of the fan and is further lifted up in height by the suction force of the fan, and then the condensed water is blown onto a heat exchanger, so that the water beating area is increased. The water beating action is realized by using the centrifugal fan, so that the water beating effect is good, the cost is reduced and the product reliability is improved.

Description

technical field [0001] The invention relates to an air conditioner, in particular to a water pumping structure of a window type air conditioner. Background technique [0002] An air conditioner is a device that makes its internal refrigerant undergo a refrigeration or heating cycle consisting of a compression process, condensation process, expansion process, and evaporation process. When the air conditioner is in the refrigeration cycle, the refrigerant compressed by the compressor and turned into a high-temperature and high-pressure state can dissipate heat to the outside in the condenser, and when it flows through the expansion valve, its temperature and pressure are significantly reduced, and then the low-temperature, low-pressure refrigerant is in the air. It absorbs heat as it passes through the evaporator and flows back into the compressor. Among them, the compression process, condensation process and expansion process are carried out in the outdoor unit of the air co...

Problems solved by technology

However, if a separate water wheel is used to fetch water, the speed of water pumping is not easy to control, and the water pumping effect is not ideal; and the number of parts increases, and the cost increases; at the same time, using a separate water wheel to fetch water, the installation position is limited, and the reliability is low
