Central air conditioner air duct cleaning machine and cleaning method

Abstract

The invention discloses a central air conditioner air duct cleaning machine and cleaning method. The central air conditioner air duct cleaning machine comprises a cleaning robot, a suction device anda controlling box, the cleaning robot comprises a walking mechanism, a lifting and lowering mechanism, a rotary mechanism and a dust removing mechanism, the walking mechanism, the lifting and loweringmechanism, the rotary mechanism and the dust removing mechanism are connected with the controlling box, the lifting and lowering mechanism is arranged on the walking mechanism, the lifting and lowering mechanism is provided with a position sensor, the position sensor is connected with the controlling box, the rotary mechanism is arranged on the lifting and lowering mechanism, the dust removing mechanism is arranged on the rotary mechanism, and a vacuum cleaner is connected with the dust removing mechanism. Compared with the prior art, a signal is transmitted to the controlling box by the position sensor when the position of the dust removing mechanism is allowed to be lifted to a preset position by the lifting and lowering mechanism to be detected by the position sensor, the rotary mechanism is started by the controlling box, so that the central air conditioner air duct is not damaged by scratching when the position of the dust removing mechanism is excessively low because of the rotation of the rotary mechanism, dead angles does not exist on the linkage points of side walls and the top or bottom, and therefore the cleaning effect is better.

Description

technical field [0001] The invention relates to the technical field of cleaning machines, in particular to a central air-conditioning air duct cleaning machine and a cleaning method. Background technique [0002] The air ducts, filters, and heat exchange surfaces of the central air conditioner will accumulate dirt during use, which will reduce the heat exchange efficiency of the system, increase the ventilation resistance, reduce the quality of the air conditioner, increase unnecessary energy consumption, and greatly increase the operating cost of the system. . And the dirt is easy to breed bacteria, causing indoor air pollution. Central air-conditioning cleaning refers to cleaning, dust removal, old removal, sterilization and disinfection of the central air-conditioning system as a whole, which can avoid indoor air pollution, improve the cooling effect, and prolong the life of each component of the central air-conditioning system. The cleaning area of ​​the air duct is the...

Problems solved by technology

[0002] The air ducts, filters, and heat exchange surfaces of the central air conditioner will accumulate dirt during use, which will reduce the heat exchange efficiency of the system, increase the ventilation resistance, reduce the quality of the air conditioner, increase unnecessary energy consumption, and greatly increase the operating cost of the system.

And the dirt is easy to breed bacteria, causing indoor air pollution

Central air-conditioning cleaning refers to cleaning, dust removal, old removal, sterilization and disinfection of the central air-conditioning system as a whole, which can avoid indoor air pollution, improve the cooling effect, and prolong the life of each component of the central air-conditioning system. The cleaning area of ​​the air duct is the largest among the above-mentioned components. Most importantly, the cleaning efficiency of the robot in the air duct directly determines the efficiency and cost of cleaning the entire central air conditioner; because the cleaning of the air duct prohibits personnel from entering due to safety considerations, the robot cleaning method is generally used, and the cleaning robot can be controlled by the controller. Enter the air duct of the central air conditioner for dust removal and cleaning; but because the entire inner wall of the air duct needs to be cleaned and dust removed, the existing cleaning robot uses the walking mechanism to drive the dust removal mechanism to rotate and clean the air duct at the same time. It is difficult to clean in place at the joint corners of two adjacent faces of the pipe
