A vase for flowers and plants is described which, thanks to an integrated air dehumidification system, composed of a refrigeration unit, is able to produce water for plants autonomously, without being connected to any water supply or without water added by an user. Through a moisture sensor placed inside the soil, it is possible to evaluate the moisture level of the soil itself and, through a pump, to deliver the produced water to the plant until the set moisture level is reached. Independently from the plant exposure, in a sunny or shaded area, from the season, both summer and winter, and even without the presence of a person, the vase is able to provide the necessary water supply to the plant. The invention meets the needs of vegetal species in the vase and also, if it is placed inside a house or an office, is able to improve the environmental comfort, reducing air humidity and providing oxygen thanks to the symbiotic relation between the vase and the plant.

It comprises an outer pot (110) having an inner cavity (115) for receiving an inner pot (130), the outer pot (110) having an interior (117) where a tray structure (118) is provided comprising trays (118a, 118b, 118c) dividing said interior (117) into sub-chambers (C1, C2, C3, C4) arranged at different levels for supplying watering liquid towards the inner cavity (115) at different heights through openings (116, 131) formed in the outer and inner pots (110, 130). Valve means (300) operated according to the hydrostatic pressure of the watering liquid in the sub-chamber (C1, C2, C3, C4) are provided for allowing controlled supply of watering liquid to the inner cavity (115). Adjusting means are provided for controlling the amount of watering liquid supplied into each sub-chamber (C1, C2, C3, C4).

Die Erfindung betrifft zunächst ein Verfahren zum Transport von Fluid bezüglich einer Batteriezelle in einem Akkumulatorgefäß, mit einer in die Batteriezelle führenden Fluidleitung. Weiter betrifft die Erfindung auch ein Verfahren zur Belieferung eines Gefäßes mit unterschiedlichen Fluiden, mit einer ersten Lieferleitung, die mit einer als Schlauchpumpe ausgebildeten Fördereinrichtung zusammenwirkt. Um ein Verfahren anzugeben, das im Hinblick auf eine zuverlässige Funktion vorteilhaft ausgestaltet ist, wird vorgeschlagen, dass die Fluidleitung mit einer selbstansaugend und/oder richtungsumkehrbar ausgebildeten Fördervorrichtung zusammenwirkt, wobei, bevorzugt, die Fördereinrichtung als Schlauchpumpe ausgebildet ist und/oder dass wahlweise in Förderrichtung vor der Fördereinrichtung (6) eine Umschaltung auf eine zweite und gegebenenfalls weitere Lieferleitung durchgeführt wird, zur wahlweisen Förderung von Fluid aus der zweiten und gegebenenfalls weiteren Lieferleitung (21, 22) mit derselben Fördereinrichtung, wobei, bevorzugt, die Fördereinrichtung als Schlauchpumpe ausgebildet ist.

The present invention provides a rainwater catchment apparatus 1 that is easily installed without renovating a building. The rainwater catchment apparatus 1 comprises a rainwater inlet 7 for introducing rainwater, a flange portion 10 engaged with a peripheral portion of a rainwater outlet 3 serving as a leading end of a drainage canal 4 formed in a building framework 2 for introducing rainwater into the rainwater inlet 7, a drain portion 9 for discharging excessive water exceeding a predetermined level to the drainage canal 4, a reservoir 5 freely fitted into the drainage canal 4 through the rainwater outlet 3, and a pumping mechanism 6 for pumping water stored in the reservoir 5 to the outside.

The plant cultivation device (1) comprises a frame (2) fixable to a wall (3) and supporting a first panel (7) presenting means (9) for retaining plants (10) with their roots (11) free in air in correspondence with a rear portion of the first panel (7) and their leaves (12) in correspondence with a front portion of said first panel (7). The device (1) also presents, in correspondence with the rear portion of the first panel (7), means (17) for dispensing water and/or fertilizer onto the roots (11) of the plants (10).

There is provided a column planter including a tank (2) to be filled with water, a plurality of planting pots (12) stackable on top of each other, to form at least one column of stacked pots (12), each pot (12) having a central opening (18) in its bottom, as well as a plurality of drainage holes (16), and a substantially vertical, substantially rigid tube (20) for each column on which tube (20), with their central openings (18), are strung the pots (12) of the column. The lower end of the tube (20) is supported in the tank (2) and the tube (20) is of such length as to at least protrude beyond the soil surface of the uppermost pot (12) in a column and an emitter (22) is attached to the upper end of the vertical tube (20). There are further provided mounting and supporting members for affixing the column of pots (12) on the tank (2), and a pump (26) having an inlet and an outlet opening and adapted to draw water from the tank (2). The outlet opening is operatively connected to the lower end of the vertical tube (20) into which the pump (26) forces the water drawn from the tank (2), to be issued from the emitter (22) at the upper end of the tube (20), wherein water issued from the emitter (22) trickles down, passing from one pot (12) into another pot (12) therebelow through the drainage holes (16), and returns to the tank (2) to be recirculated by the pump (26).
