Abstract

The invention discloses a novel hoisting and dropping machine. The novel hoisting and dropping machine is characterized in that the mounting position of an electric control box body is changed, and the electric control box body is installed above an air inlet grid; during maintenance, the whole electric control box body does not need to be disassembled, and the electric control box body can be maintained only by removing the air inlet grid; and by designing the upper boundary extension line A of a volute air outlet to coincide with the upper edge of an air outlet of the hoisting and dropping machine and designing the lower boundary extension line B of the volute air outlet to coincide with the lower edge of the air outlet of the hoisting and dropping machine, the interference between the upper boundary extension line A and a shell of the hoisting and dropping machine and between the lower boundary extension line B and a water receiving tray can be effectively avoided, and vortex formation can be avoided, so that the noise is reduced effectively, and the air outlet efficiency of the whole machine can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a hoist for easy maintenance of an electric control box. Background technique [0002] Air-conditioning noise is the noise emitted by the air-conditioning system when it is working, including the noise generated by the fan that escapes into the room and the regenerative noise at the end of the air duct. The noise produced by the fan is the modulated noise and the random noise caused by the eddy current caused by the impingement of the blades on the surrounding air when they rotate. In the criteria for judging the quality of air conditioners, the noise level has long been in the same important position as key parameters such as the cooling capacity, heating capacity, energy efficiency ratio, and air volume of the air conditioner. Reducing the noise of air conditioners has become a technical hot spot and difficulty in public relations when manufacturers develop new product...
