Sewage circulation water-saving device and method for commercial cleaning robot

Abstract

The invention discloses a sewage circulation water-saving device and method for a commercial cleaning robot. The device comprises a sewage tank, a clear water tank and a brush disc; the sewage tank is used for temporarily storing ground sewage; the sewage in the sewage tank enters a filtering water tank through a filtering device; water outflow pipelines of the filtering water tank and the clear water tank are communicated with a water outflow main pipe through a three-way valve; the water outflow main pipe is communicated with the brush disc; a liquid level sensor is arranged in the filtering water tank; an electromagnetic valve A is arranged on a water outflow pipeline of the filtering water tank; an electromagnetic valve B is arranged on a water outflow pipeline of the clear water tank; and the liquid level sensor, the electromagnetic valve A and the electromagnetic valve B are all electrically connected with a central controller. According to the water-saving device, on the basis of the signal indication of the liquid level sensor arranged in the filtering water tank, the central controller switches the clear water tank or the filtering water tank in turn to supply water, and the water-saving device does not need to frequently add water and treat sewage and ensures that water in the clear water tank is not polluted.

Description

technical field [0001] The invention relates to the fields of cleaning and water-saving technology and robot control technology, in particular to a sewage circulation and water-saving device and method for a commercial cleaning robot. Background technique [0002] With the development of artificial intelligence technology, especially the continuous maturity of unmanned driving technology, the commercialization of low-speed unmanned commercial cleaning vehicles in indoor and outdoor environments has become possible. With the acceleration of population aging and the low cleaning efficiency and high work intensity, commercial cleaning robots rely on artificial intelligence technology, including SLAM algorithms, computer vision, multi-sensor fusion algorithms and automatic path planning. and other technologies to automatically complete the cleaning task of full-coverage ground in large scenes, and liberate a large number of cleaning workers from repetitive and inefficient work e...

Problems solved by technology

However, this device flows the water in the sewage tank into the clean water tank through the filter device. Although this method can achieve sewage recycling, no matter how good the filter system is, the filtering effect will deteriorate over time, and it will be filtered into the clean water tank. There will always be impurities in the water, which will cause the water in the clean water tank to not be clean. After a period of time, there must be impurities in the clean water tank. The clean water tank must be cleaned regularly, and most of the clean water tanks of commercial cleaning robots on the market are heterogeneous structures. It is difficult to clean and maintain the water tank, and it is not easy to clean the water tank
