Internal cleaning and maintaining device for central air conditioner

Abstract

The invention provides an internal cleaning and maintaining device for a central air conditioner, and relates to the field of central air conditioners. The internal cleaning and maintaining device for the central air conditioner comprises a rotating seat, a through hole communicated with the lower surface is formed in the upper surface of the rotating seat, bristles are fixedly connected to the upper surface of the rotating seat, a supporting cylinder is in lap joint with the lower surface of the rotating seat, and a limiting sleeve is fixedly connected to the lower surface of the rotating seat. According to the internal cleaning and maintaining device for the central air conditioner, dust in the air conditioner is cleaned through mutual cooperation of a double-shaft motor, a motor shaft, the rotating seat and bristles, air above is sucked downwards through air blown by fan blades in the reverse direction by arranging the fan blades, and therefore the cleaned fly ash is sucked, the dust is prevented from entering the deeper position of the air conditioner. The problems that when an existing cleaning and maintaining device for the interior of the central air conditioner conducts cleaning and maintaining work, dust is prone to being blown into the deeper position of the air conditioner, a good cleaning effect cannot be achieved, and the service life of the air conditioner is prone to being affected are solved.

Description

technical field [0001] The invention relates to the technical field of central air conditioners, in particular to an internal cleaning and maintenance device for central air conditioners. Background technique [0002] The principle of air conditioning refrigeration, liquid vaporization refrigeration is to use the heat absorption of liquid vaporization and the exothermic effect of condensation to realize refrigeration. Liquid vaporizes to form steam. When the liquid (refrigerant) is in a closed container, there is no other gas in the container except the liquid and the vapor generated by the liquid itself, and the liquid and vapor will reach equilibrium at a certain pressure. The gas is called saturated steam, the pressure is called saturation pressure, and the temperature is called saturation temperature. When the liquid is in equilibrium, the liquid is no longer vaporized. At this time, if a part of the steam is removed from the container, the liquid must continue to vapo...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a central air-conditioning internal cleaning and maintenance device, which solves the problem that the current central air-conditioning internal cleaning and maintenance device cannot achieve a good cleaning effect because it is easy to blow dust into the deeper part of the air conditioner during cleaning and maintenance. Problems that are likely to affect the service life of the air conditioner
