Description

Device for the automatic supply of potted plants with water

The present invention is a device of the simplest type and puncture, which it enables several potted plants (flower pots) to be automatically closed with water for several weeks supply.

The devices or apparatus known today that have the above-mentioned purpose of automatic Fulfilling water supply, some have disadvantages, some of which are named as follows:

One device only supplies a single plant. The time of the automatic supply is too short, e.g. only one week,

The device is too complicated to manufacture and puncture, requiring installation Preparing or preparing dirt.

The invention has the advantage of allowing about 1 to 20 potted plants (or more) for about 3 to 6 weeks (or longer) to be automatically supplied with water. It is straightforward, easy and quick to set up and does not cause dirt. It is easy to manufacture.

The device consists of

a) the base bowl 1

b) the swimming bowl 2 and

c) a saucer filter 3 per flower pot.

ORtÖINAL INSPECTED

See the drawings Pig.1 and 2. A saucer can be used for plants that are sensitive to water. The base bowl and the floating bowl are expediently made of plastic with a wall thickness of a few millimeters (in the drawing shown as a thick line). The floating bowl is composed of a floating body k and a supporting body 5, which are manufactured in one piece. Since it has one or more holes Φ 1 cm, the support body has the water level of the base bowl. The support body carries the potted plants 6, carried by the floating body itself. The water level in the support body, provided that the load on the support body remains constant, is constant, that is, the potted plants are always at the same depth in the water. The base bowl expediently has an integral half-funnel 7.

As can be seen from the attached drawing Pig.l, the following relationship exists (dimensions: [cm]; [p]):

(a) G _B + Q ₃ - A _B = A _s = V ₃

whereby

Qg a weight of all potted plants 6 together, Go = weight of the swimming bowl 2

A _n = buoyancy of the potted plants 6 and the filter

Ao = buoyancy of the swirl bowl 2

Vo = volume of the floating bowl 2 displaced water,

Y " a specific gravity of water

The following equations also exist: (b) A _s = ^{2 2}

(c) T ₁ = r ₂ + 1

An exemplary embodiment is calculated below. It is set:

⁰ B " ^A B s ^{10 00} ° P = 20 small flower pots

= 1 000 P. ^h 3 4th cm ^r 2 = 50 cm

Then according to (a):

11,000 = Gt (5O ² - r ^ ² ) «4 r, Ai 40 cm

All the dimensions of an exemplary embodiment follow from this the device to:

T ₁ = 51 cm, r ₂ = 50 cm, r ^ = 40 cm, h ₁ (selected) = 38 cm, h ₂ = 8 cm

h, = 4 cm

Devices with other (arbitrary) dimensions can be calculated accordingly.

If the total potted plant weight is less than 10 kp (= approx. 20 smaller potted plants) the support body here based on the above exemplary embodiment with the calculated dimensions - load is the Float accordingly symmetrically

Load any weight so that the desired water level of approx. 2 - 4 cm is present in the supporting body is.

Non-aquatic potted plants are each placed on a saucer filter 3 (see drawing Fig. 2), which is made of plastic or another material and, due to its porosity, has exactly the permeability that ensures an optimal water supply for the plant. See the Darcy ¹ filter law

Q β ic. J · F or

the optimal filter permeability results in k _f = v _f / J,

v _f a the optimal filter flow rate that corresponds to the optimal water supply and

J = is the given pressure gradient.

The optimal filter permeability value k “becomes expediently determined by experiment, that is, the sub-filter that ensures an optimal water supply Q is determined by experiment.

Furthermore, the filter material is soft and elastic, so that a seal against the lower The outer edge of the pots or against the underside of the bottom of the pot is guaranteed. The reduction filters are conveniently in two or three different

Diameters, suitable for smaller, medium and larger plant pots. Next to one Lower filters with an average permeability are optionally available filters with different permeability to use.

In addition to the automatic supply of potted plants with water, the device can be used as an ornamental plant (flower) bowl, which, possibly provided with doors, represents a decorative piece of furniture, which also reduces the humidity in dry, centrally heated rooms and thus creates a healthy indoor climate.

Claims (2)

Claims Device for the automatic supply of potted plants with water, characterized in that that in a base bowl (1) of any desired, but expediently round shape, a second so-called floating bowl (2), consisting of an internal, round basic shape when used circular support body (5) and an outer ring-shaped, fixed to the support body connected floating body (4), is set, and that the dimensions of the floating bowl (2) so are chosen that in the support body (5) of the floating bowl (2) in Qebrauchsstatus for a long time a constant water level is maintained. 2. Device for the automatic supply of potted plants with water according to claim 1, characterized characterized in that to regulate the water supply to the potted plants on the support body (5) stand in the water at a constant water level, lower filter (3) are arranged, which due to its material properties (porous, elastic, which) give the plant an optimal water supply guarantee. 209819/0391 Blank page
