Circulating cooling device for bladeless fan

Abstract

The invention belongs to the field of household appliances, and particularly relates to a circulating cooling device for a bladeless fan. The device comprises a refrigeration cavity arranged in a shell. An air inlet and an air outlet are respectively formed in two sides of the refrigeration cavity, a plurality of evaporation cylinders are rotatably connected in the refrigeration cavity, and waterinlet pipes rotatably connected with the evaporation cylinders are arranged in the evaporation cylinders. Connecting cotton fixedly connected to the side wall of the refrigeration cavity is arranged at the bottom ends of the evaporation cylinders, a plurality of water absorption ropes are fixedly connected to the bottom end of the connecting cotton, and a control gear is fixedly connected to one side of each evaporation cylinder. Automatic cooling can be achieved through water evaporation and refrigerant dissolution heat absorption, refrigerant precipitation can be achieved in the water evaporation process, then cyclic refrigeration of the device can be achieved, and large-amplitude cooling of airflow can be achieved only by adding a proper amount of water in the process without making iceblocks in advance by personnel.

Description

technical field [0001] The invention belongs to the field of household appliances, in particular to a circulation cooling device for a bladeless fan. Background technique [0002] The bladeless fan is also called the air doubling machine, it can generate natural and continuous cool wind, because it has no blades, it will not cover the dust or hurt the children's inserted hands, and there is no need to worry about the hair of the personnel being entangled by the fan, etc. When using Safer than traditional fans. [0003] During the use of the bladeless fan, in order to improve the cooling effect of the bladeless fan, a water tank is generally provided in the air duct of the fan, so that when the air flow passes in the air duct, the air flow makes the water in the water tank evaporate, and then absorbs heat through water evaporation. In order to achieve a cooling effect, at the same time, in order to ensure a better cooling effect, ice cubes are generally placed in the water t...

Problems solved by technology

[0003] During the use of the bladeless fan, in order to improve the cooling effect of the bladeless fan, a water tank is generally provided in the air duct of the fan, so that when the air flow passes in the air duct, the air flow makes the water in the water tank evaporate, and then absorbs heat through water evaporation. In order to achieve a cooling effect, at the same time, in order to ensure a better cooling effect, ice cubes are generally placed in the water tank, which can further improve the cooling effect of the fan. However, in these processes, personnel are required to use refrigerators to prepare ice cubes. The block is placed inside the fan, making the actual use experience poor
