description

The invention relates to an irrigation device with a water tank, a programmable timer with a controllable drivable pump, as well as distribution main and single lines, which are arranged to individual plants at different locations, can be laid and supply the plants with water in a controlled, individually metered manner.

With such irrigation devices, it is necessary that a sufficiently large water reservoir is provided for the long-term irrigation of the plants, or that the irrigation system can be designed in this way. that the water supply can be guaranteed over a period of several weeks. It also makes sense that such an irrigation system can not only be used during the holidays, but that it can also be arranged stationary in the house. the practical handling and technical maintainability must be so simple and straightforward that it is accepted even by the technically less interested housewife.

It is known that irrigation devices are used for the pouring of plants, which can take care of the plants with water, especially during the holidays. However, it is necessary to carry out complex preparatory and construction work on the irrigation system in order to guarantee the function of the system. Many women reject this. In addition, many women want to take care of their plants while they are there for hobby reasons and only accept a practical device when on vacation, which can be assembled and disassembled within a few minutes and does not cause dirt on hands and parking spaces if handled properly. It can also be addressed to people who think practically and economically and who take up little time. Place value on cultivated ornamental plants.

The invention is therefore based on the object of a simple device with great functional reliability. large water storage container and easy connection to an additional water storage container, which can be set up in a very short time by a housewife and can be dismantled just as quickly. This object is achieved according to the invention. that the device housing is formed up to just below the upper edge as a liquid container and that the device has a Aufw ickeldorri formed as an insert, which can be inserted into the housing. The winding mandrel is preferably designed as a housing for electrical parts. ie programmable timer and a battery pack are then housed in the housing. The delivery lines to the pumps and distributors are preferably arranged on a collar of the insert and can be easily connected to or removed from the insert after removal.

In order to prevent the twisting of cables underneath the insert when inserting the insert, a preferably perforated transparent housing can be provided on the insert plate, so that the housewife can check the correct torsion-free condition of the lines themselves before using them with them perforated transparent housing is inserted into the liquid container.

According to a further embodiment, the object is achieved according to the invention in that the insert has a second collar in addition to the first collar and in that conveyor lines and a pump can be arranged between collar 1 and collar 2.

It is also possible. to provide a holder for the pump on the insert.

The advantages which can be achieved with the invention consist in particular in that the liquid container can be filled with pouring liquid almost up to the upper edge. With a particularly flat design of the device housing, a permanent arrangement of the device near plants can also be provided. It is also conceivable that the device is provided with a lid which is used as a base for plants.

Further preferred embodiments and advantages of the invention can be found in the subclaims. The invention is to be explained in more detail below with the aid of preferred embodiments.

Fig. 1 is a schematic perspective view of a first embodiment of a watering device designed according to the invention. a line with a distributor is shown.

Fig. 2 is a perspective view of a device cover, with recesses through which conveyor lines can be led to the outside in the operating state.

Fig. 3 is a partial perspective sectional view of the irrigation device, consisting of liquid container and insert part with collar, the training options of the insert part are shown in more detail.

Fig. 4 is a perspective view of a container rib formed on the liquid container, which serves as a support surface of the insert collar.

5 shows a further embodiment of an irrigation device housing in a perspective partial sectional view, which can be produced in a practical and flat design, a first and a second collar being provided on the insert part.

Fig. 6 A closer perspective view of a device insert designed according to FIG. 5, only one distributor with individual lines, a line holder and plug strips being shown. In Fig. 1, a plant irrigation device generally designated 20 is shown. This device has a liquid container 22. in which a winding mandrel 80 is accommodated. Advantageously, a vzw on the winding mandrel 80. annular collar 10 is provided, the outer diameter of which is selected so that the winding mandrel with collar can be easily inserted into or removed from the liquid container. On the job. consisting of winding mandrel and collar and provided with the reference number 81, one or more connections 24 can be provided for the liquid delivery lines. A possibility of designing the connections 24 is shown in FIG. 6. Instead of connections 24, only openings 82 can also be provided for the passage of the conveying lines 77, 78, 79 or for the insertion of hose plug-in connectors to which the lines 77, 78, 79 can be connected. A pump, which is designed in the example shown as a submersible pump 70, delivers casting liquid from the liquid storage container 22 through the main line 77 to the branch lines 78 and 79 and from dcrt to distributors 123. From which individual lines 40 emanate, which can be laid to plants and expediently be attached to the plants as shown in FIG. 6. The individual lines 40 are preferably guided in line holders, as is also shown in FIG. 6 is shown. Of course, the main line 77 can also be led directly to a distributor 123, or several branch lines can also be provided instead of only two branch lines 78 and 79. Between main line 77 and the branch lines 78 and 79, commercially available plastic push-in connectors can be used, or a multi-way solenoid valve with multiple switching options can be provided, for example, which is controlled by the programmable timer. Two or more pumps, which can be programmed differently, can also be used for different casting requirements. Of course, feed pumps can also be used which are fixedly arranged in the insert or in the housing of the liquid container. For the pumps is vzw. an electric drive is provided. The device is equipped with a programmable timer. The electrical components, such as the battery, programmable time switch etc., can be placed, for example, in the insert 81 or in a special embodiment of the liquid container wall, as indicated in FIG. 5. It is also conceivable that a transformer arranged in the mains plug is provided, as a result of which a larger space in the insert part 81. ie in the winding mandrel 80 for housing the pump is available.

The lines 78 and 79 and the distributors r 123 with the single lines 40 are normally wound up on the winding mandrel 80 above the bundle 10 and with a device cover, as shown in FIG. 2 shown, closed. The wound state of the lines is indicated in FIG. 6 and is to be expressed here by the line 679 and the dashed line 674.

The hose connectors between the lines 77, 78 and 79 can also be used to bring the line ends of the delivery lines 77, 78 and 79 relative to the collar 10 into a fixed, immovable position. This is done by, for example, Y-shaped or T-shaped hose connectors with a connection side so through the opening 82 of the collar 10 that z. on the underside of the federal government, the conveyor line 77 and on the upper side of the federal government, the forwarding lines 78 and 79 can be connected or plugged in, which is not shown further.

Advantageously, check valves 35 are arranged in the conveying lines, which prevent the backflow of pourable liquid from lines 78 and. 79 resp. Prevent 178 and 179.

It can make sense to accommodate the programmable time clock in a housing 88, which is described in greater detail in FIGS. 3 and 6. The control buttons 90 of the time switch are then expediently arranged on the housing cover of the housing 88. This housing is inserted into the winding mandrel up to the edge of the lid. In this way, the programmable time switch. as well as the battery or. a battery pack and other electrical components can be accommodated in the winding mandrel. If a three-way solenoid valve is used to selectively open the lines 77 and 78 or 77 and 79, this is expediently arranged on the collar 10 or on the outside of the winding mandrel 80. The submersible pump 70 is equipped with a delivery line 77 and with an electr. Connection line 92 connected. The electrical connection line 92 is connected on the one hand to an electric motor in the submersible pump and on the other hand to a program-controlled power supply.

Using the example of the pump 170 shown, it is to be demonstrated that the pump can also be arranged in a secondary vessel, which can be larger than the liquid storage container 22. The associated secondary vessel is not shown in any more detail, however. The delivery line 177 is then led through a lateral edge opening 14 to a distributor 148, from which the delivery lines 178 and 179 extend. A Y or T piece can be used as a distributor, as already described above. This Y-piece or T-piece can then, as also described above, serve to firmly and immovably fix the conveyor line ends 177, 178 and 179 with respect to the collar 10. The delivery lines can also be passed directly through the openings 82 in the collar 10. The delivery lines 178 and 179 are connected at their other ends facing the plants to distributors 123, as already described. Of course, lines 177, 178 and 179 can also be connected to connections 24.

When inserting the insert 81, it can be useful if support strips or support pieces 4 are provided on the inside of the liquid container wall 22, on which the insert can be placed. The insert 81 can also be arranged fixedly, but releasably, on the liquid container 22, for example by means of screws or by means of corresponding screw threads on the liquid container and on the insert. However, a preferably perforated transparent housing 30 can also be arranged on the insert. In this case, the torsion-free condition of the delivery lines can be easily checked and the insert with transparent housing can be inserted together in the liquid container. The perforation makes sense because the casting liquid can flow through the perforation. In order to be able to lead the delivery lines 78, 79 and 177 out with the cover closed, recesses 2 are expediently provided. Similar recesses can also be provided in the cover, as described in FIG. 2.

The advantage of this embodiment described in FIG. 1 is that the preferably annular winding space formed from insert 81 and liquid container 22 above collar 10 can be used both as a water reservoir and as a winding container. Another great advantage is that the submersible pump including the electrical connection line 192 and the extended main delivery line 177 are removed from the device and. can be relocated to a larger secondary vessel, not shown, whereby the delivery line 177 and the electrical connecting line of the pump 192 can remain connected to the device insert 81 at their ends pointing away from the submersible pump, so that the housewife can move the secondary vessel within a few seconds can be made.

When using two pumps, it may make sense to design the time switch so that two program sequences can be set. It is then also possible to arrange one or both pumps in one or two secondary vessels. It is then also possible to differentiate between normal irrigation water and nutrient solution liquid and to supply both liquids in different doses. In this way, the housewife can, for example, take intensive care courses on her plants over a period of several weeks. If a controllable solenoid valve is used at junction 48, two different programs can also be run with one pump if the timer is designed accordingly.

Basically, different feed pump designs are conceivable. For example, the pump and motor can be combined in one housing. It is also possible to arrange the pump and drive motor separately. The motor and pump can be connected by a long drive shaft, which is mounted in a tubular connecting piece, the pump being arranged near the bottom of the liquid storage container 22 and the electric drive motor preferably being arranged above the water level of the irrigation water. If the pump and the electric drive motor are designed separately, the drive motor can be arranged in the winding mandrel and a further tubular riser pipe, for example arranged laterally or centrally in the winding mandrel, can serve to mount the pump drive shaft. Of course, the drive motor can also be arranged below the water level in the device if the drive shaft of the electric motor can be sealed off from the pump arranged in the irrigation water.

The programmable time switch can preferably be adjustable in such a way that a casting time can be set in each case from a few seconds to several minutes and that a waiting time until the next casting process is possible from several hours to several days. A work cycle then consists of a pre-settable casting time and a pre-settable waiting time. Then a new work cycle begins.

The delivery lines 77, 78 and 79 and 177, 178 and 179 are expediently made of silicone rubber, because such lines can be wound up more easily.

Distributors 123 with individual lines can be used in any version.

In Fig. 2, a device cover is shown. In the device cover 21, an opening 19 is preferably provided, which is slightly larger than the wickeldbrh 80 and an approach 17, the vzw. is slightly smaller in the outside diameter than the inside of the wall 22. If the lid 21 is placed on the device, then the opening 19 must match the winding mandrel 80 and the shoulder 17 preferably the inner diameter of the liquid container 22.

Recesses 3 can be provided in the shoulder 17 of the cover and on the edge of the cover, through which the delivery hoses can be held when the device is closed and in the operating state. After use, the lines can be rewound around the winding mandrel as described above and the device can be closed again with all of the delivery lines that are properly wound in the device. If the device is used continuously, it can also be used as a base for a plant.

In Fig. 3 the device housing is shown in a perspective partial sectional view. The housing 322 is designed as a liquid container and has locking lugs 34 on the inner wall side, on which the insert part 381, consisting of the winding mandrel 380 and collar 310, can be placed, as is shown in more detail in FIG. 4.

A particular advantage is that a perforated transparent housing 330 can be provided on the underside of the insert 381, in which a submersible pump 370 together with a delivery hose 377, and an electrical feed line 392 can be accommodated. A pump holder can be provided in the transparent housing, but is not shown in more detail. It can be useful to arrange a second winding mandrel for the lines 377 and 392 below the bundle 10, which is approximately in the form of the second bundle 611 shown in FIG. 6 and whose extension 509 or 609 is extended for this application and as Winding mandrel. Of course, the winding mandrel 380 can also be extended so far down that the conveyor lines can be wound on it below the collar 310. A pump holder can also be provided on this extended winding mandrel 380.

The transparent housing 330 can be plugged onto the extension 331 or connected in another suitable manner to the insert part 381. With such an arrangement, the housewife can convince herself at any time whether the hose lines are arranged in a proper condition, ie without being twisted.

In the version with a perforated transparent housing, insert 381 and transparent housing 330 can of course also be connected, for example by plugging the two parts together, in such a way that the detents 34 on the inside of the device liquid wall can be omitted.

The winding mandrel 380 can be closed on the underside, which is to be expressed by 399. The interior of the rewinder can then be used as a housing for electrical components.

When using an immersion pump 370, a riser 398 is expediently provided, which is preferably arranged either on the inside of the winding mandrel or in the wall of the winding mandrel, and its opening 397 on the upper side to the interior of the winding mandrel 380 and on the lower side to the Space leads under the plate 310/399. The riser pipe can also be led laterally out of the wall of the winding mandrel, which is not shown in detail. The feed line 392 is guided through the riser pipe into the interior of the winding mandrel 380. This constructive design prevents the irrigation water from penetrating into the interior of the winding mandrel designed as an electrical housing when the maximum level is reached, which is to be indicated by reference numeral 35. Connections 324 can be provided on the insert part 381, preferably on the collar 310, as is shown in more detail in FIG. 6. A further very expedient and simple guidance of delivery lines can be achieved if openings 382 are provided in the collar 310 through which the hose lines are passed. The lines 377 and 392 can be led through the recess 383 to a pump arranged in a secondary vessel. To hold the delivery lines 378 and 379, cutouts 32 can be introduced at the edge of the vessel. If the lid 21 is placed on the device, then the opening 19 must match the winding mandrel 80 and the shoulder 17 preferably the inner diameter of the liquid container 22.

In the shoulder 17 of the cover and on the edge of the cover, recesses 3 can be provided, through which the delivery hoses can be held when the device is closed and in the state of septicemia. After use, the lines can be rewound around the winding mandrel as described above and the device can be closed again with all the delivery lines that are properly wound in the device. If the device is used continuously, it can also be used as a base for a plant.

In Fig. 3 the device housing is shown in a perspective ivischeh partial sectional view. The housing 322 is designed as a liquid container and has latching lugs 34 on the inner wall side, on which the insert part 381, consisting of winding mandrel 380 and sound 310, can be placed, as is shown in more detail in FIG. 4.

A particular advantage is that a perforated transparent housing 330 can be provided on the underside of the insert part 381, in which a submersible pump 370 together with delivery hoses 377, 378, 379 and an electrical feed line 392 can be accommodated. A pump holder can be provided in the transparent housing, but this is not shown in more detail. It can make sense to arrange a second winding mandrel for the lines 377, 378, 379 below the bundle 10, which is designed approximately in the manner of the second bundle 611 shown in FIG. 6 and whose extension 509 or 609 is extended for this application and serves as a winding mandrel. Of course, the winding mandrel 380 can also be extended downwards to such an extent that the delivery lines below the collar 310 can be wound thereon. A pump holder can also be provided on this extended winding mandrel 380, 8 The transparent housing 330 can be plugged onto the extension 331, or can be connected to the insert part 381 in another suitable manner. The time switch housing 388 with the adjustment buttons 309 is indicated by dashed lines and is preferably cylindrical towards the winding mandrel side and designed to accommodate the programmable time clock, which is to be indicated by the reference number 301.

Furthermore, it is also conceivable that the timer and a transformer connected to the power supply are housed together in an external housing outside the device, this electrical subunit having a cable connection to the power plug and a connection to the pump in the device. Parts of this version or the whole can also be integrated in the power plug.

This arrangement enables a submersible pump to be arranged directly in the winding mandrel and, if necessary, can also be removed and used in a secondary vessel.

A holder for the pump 370 (not shown in detail) can preferably be arranged on the underside of the base 399.

The placement of the federal 410 is shown in more detail in FIG. 4. Ribs 44 are expediently arranged on the liquid container wall 422, which fit into recesses of the collar 410. As a result, the insert with collar 410 can be snapped into place in a simple manner.

5 shows a further embodiment, the detailed function of which is described in more detail in FIG. 6. The expanded version consists in that a second collar 51 1 can be placed on the insert 581, preferably on the winding mandrel 580 to the first collar 510, from below. which preferably has an extension 509. This will wi rd through housing 522 and. thus insert 581 completes a first winding space 515 for winding an extended main pump line and the pump 570 can also be arranged in this space, as shown in the drawing. The space 516 above is used to wind up the extension lines with the distributors arranged thereon when the device is to be put out of operation and switched off. Irrigation water can be filled up to level 512 in the operating state. Thus, the irrigation water fills the previously mentioned rooms 515 and 516 up to the maximum stated height. Reference number 533 is intended to represent an electrical box arranged on the side wall, in which a programmable time switch can be accommodated. On this electrical equipment box, a cover can be arranged with control buttons, similar to the described embodiment, but this is not shown further.

It is also conceivable for the pump to be held in a special embodiment of the lower winding part, which is to be expressed by reference number 555. A submersible pump can be accommodated in this curved receptacle. With this housing design, too, a pump arrangement permanently installed in the housing is also conceivable, as described above, instead of a submersible pump.

Of course, the bottom cover 599 of the winding mandrel 80 can also be omitted in this embodiment if the electric housing is arranged in the liquid container wall or elsewhere or externally.

In fig. 6 is shown in a perspective partial sectional view the further embodiment of the invention, which makes it possible to accommodate the submersible pump in a particularly space-saving arrangement so that the height of the device can be significantly reduced. Here, the submersible pump 671 is arranged laterally under the first collar 610 and between the housing wall 622 of the liquid container, indicated by dashed lines, on the one hand, and the winding mandrel 680, on the other hand, the intended position of the pump being indicated by dashed lines and designated 670. The housing of the winding mandrel 680 can extend to the floor or in the vicinity of the floor. It may make sense to provide a second collar 61 1 which can be plugged onto the winding mandrel 680 from below and which preferably has special receptacles for holding the pump after the pump side 670. Thus, on the one hand, the delivery line 677 and the electric line 692 can be wound on the mandrel 680 without twisting between the first collar 610 and the second collar 61 1 and cannot slide downward, and on the other hand the pump 670, which also lies between the first collar 610 and the second collar 611, are additionally held in an immovable position. Such a pump holder can also be provided directly on the winding mandrel 680. Thus, the insert part 681 with the coiled lines 677 and 692 as well as with the pump can be inserted into the liquid container 622 and can also be removed without the lines and pumps slipping below the collar 610.

At the point designated 648, a plug connection for connecting the delivery lines 677, 678 and 679 can be provided. As already described above, a three-way connector, which is designed as a Y or T connector, is expediently also used here. It makes sense to insert a connecting pipe of this connecting piece through the opening 614 in such a way that the delivery line 677 can be connected on the underside of the federal government 610 and the delivery lines 378 and 37 can be connected on the top side, but this is not shown further. As a result, the delivery lines 377, 378 and 379 are each held at one end in a largely immovable position with respect to the collar 610. Check valves 635 are expediently arranged in the conveying lines 378 and 379 above the collar 610.

Of course, other connection options for the delivery lines 377, 378 and 379 are also conceivable. In the illustration in FIG. 6, the T-piece or Y-piece is arranged below the collar 610, for example, and therefore two openings 614 are arranged for the delivery lines 378 and 379.

Instead of cable bushings 614, connections 624 can also be provided, which are preferably arranged on the collar 610 or at another location on the insert part 681. The connections 624 have connection pins 627 and 628 on the top and bottom. to which the production lines can be connected. Check valves can be integrated into these connections 624. Two or more connecting pins 627 can also be provided on the upper side of the connections 624. Then on the underside, ie on the connection pin 628, the delivery line 677 and on the top, ie on the connection pin 627, for example, the delivery lines 678 u. 679 can be connected. If there is more than one upper connecting line, the check valves are expediently integrated in the upper connecting pin part 627, so that each individual line is protected against backflow of pouring liquid.

The submersible pump 671 or 670 is connected to an electrical connection line 692 and a delivery line 677. The electrical connection line 692 leads to the electrical components. i.e. in the Aufwickeldor rn 680 designed as a device housing. The entry is preferably on the underside. A recess 612 is provided on the edge of the collar 61 1 so that the electrical connecting line 692 can be guided from the outlet side at the bottom of the winding mandrel to the annular space 61 5 formed from the two bundles 610 and 611. If the second collar 61 1 has a ring-like distance piece 609 on the underside, then a recess 608 must also be provided on the side facing the bottom of the liquid container, which serves to pass the line 692 through.

In this embodiment, too, a riser pipe 698 is provided, which is firmly connected to the housing of the winding mandrel 680 and the bottom 699 thereof, or is preferably integrated therein, and prevents watering water from rising up in the winding mandrel 680 designed as an efectro housing. The electrical drive line 692, which is connected on the one hand to the submersible pump motor 671 or 670 and on the other hand to the electrical components, can be guided through this riser pipe 698. The riser pipe should be so high that even with a slight inclination of the device, irrigation water cannot get into the electrical sub-tank. In addition to a timer, a winding or battery pack or other components can also be arranged in the winding mandrel. The water level of this embodiment can then, as already described above, reach up to about the rim of the liquid storage container in the filled state. On the lower side of the riser pipe, the opening can also be arranged laterally, which is not shown further. It is also conceivable to lead the line 692 down on the outside of the winding mandrel. In the device, as in the previously described embodiment, there are the spaces filled with casting liquid, ie here the space 615, 616 and the space below the collar 611, and a drying room for electrical parts, which can be formed here in the interior of the winding mandrel 680 . The irrigation water can rise in the riser pipe 698 without the water getting into the drying room. Of course, a seal in the riser pipe can also be used, or the riser pipe can be completely dispensed with when the line 692 is sealed off from the interior of the housing 680 into the space containing the casting liquid. This also applies to the embodiment shown in FIGS. 1 to 3.
