    becomes it. By optimizing the water purifier's orientation towards the sun to take advantage of the increased amount of solar energy to which the container is exposed, it also causes an increased load on both the transparent disc which is joined to the absorbent part of the water purifier, the box. which is also hot when it is set up perpendicular to the short side of the box against the ground The stress on the joint edges becomes high and there is a risk of leakage and deformation of the materials. To increase the robustness, you can increase the thickness of the material in the container, but if you increase the thickness of the transparent disc, you reduce the amount of UV light that is let through, which delays the purification process of the water. The transparent surface should transmit maximum with UV light but should be as little as possible obscured by ear-strengthening constructions that hold the two joined parts (box and disc) so eg nets, straps or other ear straps are not preferable.
    Brief description of the invention In order to find the optimal angle of incidence of solar radiation for the water purifier, a mark (3.) in the transparent, sunlight-transmissive disc (1.) has been arranged so that a shadow image (6.) falls on the absorber surface (bottom of the box) ( 2.) directly below the mark if the angle of incidence is 90 ° between the solar radiation and the impact surface.
    The mark can be placed anywhere on the disc, but it should clearly give rise to shadows. The mark can be a thickening in the material, as a covering surface, as lines or as other geometries that can be applied to or in the transparent sheet. Another solution is to make a mark in the absorber in line with the mark on the disc, in order to curb maneuver the container until the shadow falls into the mark. If the shadow on the absorber falls outside the mark in the transparent disc, the box must be aligned so that the shadow falls into place. As the energy losses become large if the water purification tank is exposed incorrectly, ie more flat against the surface or more steep, it affects the effect on the purification and prolongs the time for exposure, which can mean that the purification process can not be completed during the hours the sun is up during the day. The portable water purifier can be adjusted in both latitude and angle to the sun depending on geographical location, altitude, season and time of day. As the alignment process increases the amount of radiated solar energy, it also gives rise to an increased pressure inside the container and an increased load on the materials. To reduce shape changes in the plastic and reduce the risk of leakage in glue or welded edges (4.), a transparent disc in a concave (l. 1) or a convex (1: 2) shape at the deepest and highest point in the middle can distribute the pressure. smoother over the board and then provides a relief on the joint edges that are between the box and the board. A center pillar (5.) is a possible attachment point for the transparent board together with the joint edges between the outer edges of the transparent board and the box. The transparent disc can therefore be relatively thin and can thus let through the largest possible amount of UV light in order to be able to effectively clean and heat the water. The transparent disc can be mainly square, rectangular, oval or round in its design.
