Description

Ash water recycling device for vehicle toilet

Technical Field

The utility model relates to the technical field of vehicle sanitary systems, in particular to a device for recycling ash water in a vehicle toilet.

Background

The existing vehicle sanitation system is a system which uses compressed air as power and uses electricity (generally DC 24V) for control. As shown in fig. 1, the vehicle sanitary system is installed under a vehicle (under a vehicle floor, a vehicle body suspension), with an under-vehicle dirt box 11 (including a vacuum generator, a vacuum switch, a solenoid valve, etc.) and a grey water temporary storage box 10 (including a full water level, a drain valve, a vent pipe, etc.) of grey water.

In the vehicle sanitary system, a toilet system (including a flush solenoid valve, a water booster 5, a pneumatic flush valve 16, a toilet 4, a nozzle, a drain valve 12, and the like) and a basin 2 (a water containing valve) are installed in a vehicle cabin (in a bathroom).

Basic functional introduction:

under-vehicle dirt box 11: for collecting dirt and waste water, and detecting the set value of the vacuum pressure switch in the standby state. When the pressure of the tank body is higher than a set value, the system controls the electromagnetic valve to be opened, compressed air carries out a vacuum generator and generates vacuum in the sewage tank below the vehicle. When the pressure reaches the vacuum pressure switch set point, the solenoid valve closes, the system stops evacuating, and vacuum is maintained in the under-vehicle dirt box.

Grey water temporary storage box 10 (collection and transfer of grey water): the ash water of the washing basin on the vehicle flows into the ash water temporary storage box by utilizing the height difference (gravity), and when the ash water is accumulated to reach the liquid level of the ash water temporary storage box. The system controls the drain valve 12 to open, the grey water temporary storage tank 10 is communicated with the under-vehicle dirt tank 11, and grey water is transferred from the grey water temporary storage tank to the under-vehicle dirt tank 11 under the action of vacuum.

Toilet bowl composition (flushing action): the lower cavity of the water booster 5 is filled with water, and when flushing is needed, the system controls the flushing electromagnetic valve 15 to be opened electrically. Compressed air enters the upper chamber of the water booster 5 and simultaneously opens the pneumatically controlled flush valve 16, and pressurized water is flushed through the nozzle into the toilet bowl 4.

Toilet bowl composition (blowdown action): the system controls the drain valve below the toilet bowl 4 to open, the toilet bowl 4 is communicated with the under-vehicle dirt box 11, and dirt is transferred from the toilet bowl 4 into the under-vehicle dirt box 11 under the action of vacuum.

Basin 2: the water valve is operated, and the produced greywater is collected by the basin and flows into the offal temporary storage tank 10 through the pipeline.

The water in the basin 2 finally flows into the filth tank, and the amount of purified water and the amount of discharged filth are large.
