AI Technical Summary
Camper vans often face water scarcity due to limited onboard water supplies, necessitating efficient water reuse systems to maximize water usage.
A water reuse system integrated within a camper van, utilizing a sink with a faucet, a sewage tank, and a series of filters including a filter for coarse solids, a reverse osmosis membrane filter for bacteria and chemical removal, and a calcium carbonate filter for pH neutralization and taste improvement, effectively recycling water for reuse.
The system significantly increases the usable water supply within the camper van, providing stable and filtered water for extended periods without relying on external water replenishment, even in areas where water is scarce.

Abstract
Description
[Technical field]
[0001] Wastewater is taken from the drainage system and purified using a filtration filter and a reverse osmosis membrane filter, and the taste of the treated water is improved by remineralizing and neutralizing it using calcium carbonate (calcite) filter material. [Background technology]
[0002] The device is based on a sink with a faucet that uses an electrically operated water pressure pump that can be mounted on a vehicle, and is equipped with a water purification and wastewater tank, and is equipped with a device that can reuse wastewater. Summary of the Invention [Problem to be solved by the invention]
[0003] The amount of water that can be carried in a camper is limited, and by reusing water that has already been used, the limited amount of water can be used effectively.
[0004] The explanation is based on the diagram below. Water pumped up from C is used in A and B, then collected in the wastewater tank at D, where it is filtered out of large foreign objects at E, then fine solids are removed in tank G, and bacteria and chemicals are removed in the reverse osmosis membrane filter at H, extracting only the water molecules. The calcium carbonate (calcite) filter at J neutralizes the pH and adjusts the taste before returning the water to tank C. Effects of the idea
[0005] By increasing the amount of purified water available and stably filtering it inside the vehicle, water can be consumed only within the vehicle without relying on external sources, and water can be replenished less from outside. It also makes it possible to operate for long periods of time even in places where it is difficult to replenish water. [Brief description of the drawings]
[0006] [Figure 1] A diagram showing the components of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0007] By installing a model with a sink with a faucet and drain inside the camper van, and a reflux device with a filtration filter and reverse osmosis filter, it is possible to obtain water even in places where it is difficult to refill the water tank. EXAMPLES
