Graywater contamination collecting system for vehicle, control method and vehicle

Abstract

The invention relates to a graywater contamination collecting system for a vehicle, a control method and a vehicle. The graywater contamination collecting system for the vehicle comprises a graywaterdrainage device, a graywater temporary storage box, a water closet, a water tank, a graywater contamination box, a flushing switch and an electric control unit; the water tank is connected with a water flushing pipe of the water closet through a water supply pipeline; a booster water pump, an energy storage tank and a water flushing electromagnetic valve are connected to the water flushing pipe inseries in sequence, wherein the booster water pump is used for increasing the water flushing pressure; the energy storage tank is used for temporarily storing pressure water; and the water flushing electromagnetic valve is used for controlling the closing and opening of the water flushing pipe; the bottom of the water closet is connected with the graywater contamination box through a blow-off pipe; the graywater drainage device is connected with the graywater temporary storage box through a first water drainage pipe; the graywater temporary storage box is connected with the graywater contamination box through a second water drainage pipe; a first electric gate valve is arranged on the blow-off pipe; a second electric gate valve is connected to the second water drainage pipe in series; anelectric vacuum pump used for keeping a vacuum state of the graywater contamination box is connected to the graywater contamination box; and the flushing switch, the water flushing electromagnetic valve, the first electric gate valve, the second electric gate valve, the booster water pump and the electric vacuum pump are connected with the electric control unit. The graywater contamination collecting system for the vehicle has the characteristics of less system equipment, simple and compact structure, low fault rate, guaranteed water flushing effect and the like.

Description

technical field [0001] The invention relates to a water supply sanitation equipment, in particular to a gray water and sewage collection system and a control method for vehicles, and also to a vehicle equipped with the gray water and sewage collection system. Background technique [0002] At present, gray water and dirt collection devices are generally installed on vehicles such as mobile buses, EMUs, airplanes, and portable toilets, and gray water tanks and dirt tanks are installed on the vehicles to collect waste water collected from the vehicles. The gray water and sewage discharged from toilets, floor drains and toilets meet environmental protection requirements and keep the overall environment clean and tidy. [0003] The gray water and dirt collection device of the existing vehicle adopts two beneficial modes, one is gravity type, and the other is the mode of vacuum collection. [0004] The gravity system is generally relatively simple, and the sewage flows into the g...

Problems solved by technology

However, because the booster pump cannot build up enough pressure at the moment of starting, the flushing effect is affected, and the time for action reaction is also increased.
