Description

Primary water and gray water comprehensive utilization system for RV

technical field

The invention relates to a comprehensive utilization system of primary water and gray water for a caravan, belonging to the technical field of environmental protection.

Background technique

With the improvement of people's living standards, RVs have gradually entered people's daily life, providing a convenient and comfortable environment for people's journey life. However, due to all kinds of living facilities in the caravan, the water consumption is large, but it is often inconvenient to add water during the journey. The existing caravan usually only has two water inlets, and there is no consideration for adding water for short-distance journeys. Nozzle, resulting in inconvenience and waste of water resources.

Existing caravans do not make good use of water resources. After primary use, the water becomes domestic sewage and is discharged directly without recycling, purification and reuse. At the same time, it is not considered to use the rainwater collected by the caravan during driving in rainy days to clean the gray water tank. Replenishment of water cannot realize the secondary utilization of water resources, resulting in great waste.

In the RVs commonly used today, the heating method of the hot water tank is relatively simple, and electric heating is mostly used. The heat utilization of automobile exhaust and the combination of new energy such as solar panels and electric heating are not considered, resulting in high energy consumption.
