BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fresh water generator that is convenient for storage and use.

2. Description of the Related Art Water fresheners, for example, used in emergency situations such as large-scale earthquakes, storms and floods, fires, and droughts when drinking water or domestic water (washing water, bath water, dishwashing water, etc.) cannot be secured. Many emergency desalination devices of the type have been proposed. This desalination device can be used in emergency situations such as those described above.
Using fresh water such as seawater, river water, lake water, pool water, fire-prevention water, or the like as raw water, drinking water or living water is produced by a fresh water producing unit.

In such a fresh water generator, as means for pumping and pressurizing raw water, an engine, a motor, or a pump driven by human power is used. The fresh water is stored in a special or general water tank.
A specific example is a plastic tank. The purified water stored in the tank is used as drinking water or domestic water.

[0004]

The above-mentioned fresh water generating apparatus is usually covered with a cover during storage in order to protect the fresh water generating unit from dust, dirt and falling objects. However, since an inexpensive sheet cover for dust prevention is usually used, there is a possibility that important equipment of the fresh water generator may be damaged by a fallen object during an earthquake or the like.

[0005] Further, since the water storage tank is stored separately when the fresh water generator is stored, there is a problem that a large storage space is required for the water storage tank. Further, when the water storage tank is a plastic tank, it may be damaged by a fallen object during an earthquake or the like, and may not be used for water storage. In addition, there is a problem in carrying, for example, in terms of weight and volume.

[0006] The object of the present invention is to solve the above problems,
