FIELD: aqua vending machines.
SUBSTANCE: invention relates to aqua vending machines, i.e. to drinking water vending machines by means of automatically controlled dispensing of water into a container of a water buyer, which is installed in a water filling chamber equipped with a spring-loaded door closing the inlet opening of this chamber. Technical problem consists in the need to provide shock-free closing of the spring-loaded door of the filling chamber without reducing the compression force of its door spring. Filling chamber is a box with a branch pipe. Box has an inlet opening of rectangular shape, which is closed by an inlet spring-loaded door. Sides of opening rectangle are located in vertical plane of opening and are formed by four edges, namely free edge of left side wall of box, on which door is installed by means of door hinges, free edge of right side wall of box, free edge of upper wall of box and free edge of box bottom. Area of the free edge of either the said right side wall, or the said upper wall, or simultaneously each of them is made in the form of a bent L-shaped section. Wall of this profile is located parallel to the plane of the inlet opening and is shifted inside the box by the width of the shelf of this profile relative to the plane of the inlet opening. By means of this displacement in the entrance opening in the direction towards the rear wall of the box, a recess is formed, which is limited only by the wall of the specified profile and intended for placement in this recess of the entrance door in its closed position with a stop against the wall of the specified profile and with transverse gaps along the perimeter of the door between the sides of the perimeter of the door and adjacent to them inlet opening perimeter sides, wherein said gaps do not exceed 2 mm.
EFFECT: providing optimum balance of forces of door closing and resistance to this closing by means of aerodynamic braking (piston effect).
