Definitions

  • the invention relates to a water suction device with a sealed supply container having an inlet and outlet, which is connected to a suction device and a pump.
  • a sludge sucker with a suction element which is connected to a receptacle, and includes a motor for generating a suction flow.
  • a drain element is connected to the receptacle.
  • the motor is connected to a ball valve, which is located near the intended fill level of the receptacle. When the fill level limit in the receptacle is reached, the ball valve closes, making the motor run audibly faster. This is the sign for the user to switch off the motor via a remote control, after which the vacuum in the receptacle is eliminated, so that a vacuum valve opens and the sludge inside the receptacle runs out through the drain element until the receptacle is completely emptied.
  • the motor can then be switched on again using the remote control to repeat the process.
  • This sludge sucker is disadvantageous in that only discontinuous work is possible with it.
  • it is imperative that the free end of the drain element is at a point lower than the sludge sucker in order to ensure that the receptacle is emptied.
  • a water suction device with a storage container which comprises an electromotive suction device and, on the other hand, a submersible pump with a float switch, which is arranged within the storage container.
  • a water suction device continuous work is possible since the submersible pump transports the water out of the storage container during operation of the suction device. Since the suction vacuum of the vacuum cleaner is relatively small, the height over which the water can be sucked in is also relatively low. It is therefore necessary to set up the water vacuum cleaner near the water level, which is a disadvantage in confined spaces. Incidentally, the parallel operation of two electric motors, namely that of the vacuum cleaner and that of the submersible pump, is essential.
  • the object is achieved in that the suction device is assigned a valve device and the pump is assigned a level monitoring device, which has the effect that when a certain level is reached the pump sucks the water through the inlet and conveys it through the outlet.
  • the storage container is filled to a certain level by means of the suction device, from which the pump takes over both the suction of the water and its removal via the storage container, so that continuous work is ensured.
  • the suction of water Due to the high suction power inherent in the pump, the suction of water is possible both over relatively long distances and relatively high altitudes.
  • the water suction device is not only suitable for suctioning clear water, but rather also for removing water or mud contaminated with coarse particles.
  • the suction device it is possible to place the suction device so that it is spatially separate from the storage container in such a way that it is not in the vicinity of the water to be sucked up and thus outside a danger zone.
  • the storage container has a relatively compact size in the case of an externally spaced suction device.
  • the suction device is preferably connected to an outlet of an suction nozzle inserted into the storage container.
  • the storage container has a compact structure with a low weight and is therefore easy to handle.
  • the suction nozzle expediently has a water protection device comprising a float valve at its end projecting into the storage container.
  • the suction device is designed as a hand pump and / or an aspirator driven by an electric motor.
  • the hand pump represents a cost-effective embodiment of the suction device, with which water is sucked in until a certain fill level is reached within the storage container, from which the pump takes over the conveyance of the water.
  • the suction motor driven by an electric motor it is more convenient to achieve the specific filling level within the storage container, especially when a relatively large amount of air is sucked in with the water.
  • the intake manifold comprises an access protruding into the open for the connection of a vacuum hose.
  • the pump is advantageously designed as a submersible pump which is inserted into the storage container and generates a greater negative pressure in the storage container than the suction device.
  • the valve device for the suction device can be controlled in such a way that the valve device is closed when the pump is running in order to separate the suction device from the storage container in terms of flow.
  • the submersible pump is expediently connected to a float switch for monitoring the fill level of the storage container.
  • an electrical and / or electronic control unit is integrated in a voltage supply line of the pump and is coupled to level sensors arranged one above the other in the storage container in order to switch the pump on or off.
  • the control unit is preferably connected to the suction device on the one hand for switching the voltage supply on or off when the pump is switched on or off.
  • the control unit provides for alternating operation of the pump or the suction device, which is particularly necessary when water-laden air, for example foam, is sucked in order to protect the pump from damage on the one hand and at the same time the continuous work with the Ensure water suction.
  • control unit When a maximum fill level detected by the upper fill level sensor is reached, the control unit preferably switches the pump on and the vacuum cleaner off and on reaching it from the lower level sensor detected minimum level on and off the pump.
  • a control switch is preferably assigned to the control unit, the application of which causes the pump to operate below the fill level.
  • the valve device comprises a first in the outlet of the intake nozzle and a second in the drain of the reservoir or a Drain hose used shut-off valve.
  • the valve device expediently has a third shut-off valve which is inserted into the connection of the intake manifold.
  • the valves assigned to the intake manifold are closed when the pump is started up and are open during the operation of the intake device.
  • the shut-off valve inserted in the outlet of the storage container is open when the pump is running and closed during the operation of the suction device.
  • the shut-off valves can be removably arranged for easy cleaning of dirt.
  • the shut-off valves are preferably designed as check valves aligned in such a way that they close corresponding passages if the pressure on the side facing the storage container is lower than the pressure on the opposite side.
  • a filter device is assigned to the inlet within the storage container.
  • the filter device can comprise, for example, coarse and / or fine filters in order to separate particles of different sizes from the water. This makes the water cleaner particularly suitable for cleaning swimming pools or ponds or cisterns, since the dirty water drawn in flows through the filter device, leaves it cleaned of particles and can be returned to the swimming pool, pond or cistern via the drain as purified water.
  • FIG. 1 is a schematic sectional view of a water suction device according to the invention
  • FIG. 2 shows a schematic sectional illustration of the water vacuum cleaner according to FIG. 1 in an alternative embodiment
  • Fig. 3 is a schematic sectional view of the water vacuum cleaner according to Fig. 1 in a further alternative embodiment
  • FIG. 4 shows a schematic illustration of a storage container of the water suction device according to FIG. 1.
  • the filter housing 1 comprises a storage container 1 which is closed airtight with a lid 2.
  • a filter housing cover 3 is inserted into the cover 2 for closing a filter housing 4 projecting into the pressure-stable storage container 1.
  • the filter housing 4 comprises a funnel-shaped sieve insert 5 and is used to hold coarse-grained material, which is to be removed after opening the filter housing cover 3.
  • An inlet 6, which is connected to a suction hose 7, is inserted in a sealed manner in the filter housing cover 3.
  • a suction device 9 designed as a hand pump 8
  • the cover 2 seals a suction nozzle 10, the end of which protrudes into the reservoir 1 carries a water protection device 12 comprising a float valve 11.
  • a first shut-off valve 15, designed as a check valve 14, of a valve device 16 is inserted into an outlet 13 of the intake connector 10, which is connected to the hand pump 8, and further comprises a second shut-off valve 18, also designed as a check valve 17, in a drain 19 projecting through the cover 2.
  • the drain 19 is connected, on the one hand, to a pump 21, which is arranged on the bottom of the storage container 1 and designed as a submersible pump 20, and, on the other hand, to a drain hose 22.
  • the submersible pump 20, the voltage supply Line 23 is also passed through the cover 2 ' , comprises a float switch 24 for monitoring the fill level of the storage container 1.
  • the storage container 1 has a drain valve 25 on the bottom.
  • the check valve 17 inserted in the outlet 19 is closed, the float valve inserted in the intake port 10 and the check valve 14 inserted in the outlet 13 of the intake port 10 are opened.
  • the hand pump 8 which can be removed from the storage container, water is sucked in via the inlet 6, which is cleaned of particles in the filter housing 4 and reaches the storage container 1 until it reaches a certain fill level.
  • the float switch 24 switches on the submersible pump 20, which generates an increased vacuum in the reservoir 1 compared to the hand pump 8. Because of this, the check valve 14 inserted in the outlet 13 of the intake port 10 is closed, with the result that the hand pump 8 is fluidically decoupled from the storage container 1.
  • the check valve 17 ′ assigned to the outlet 19 is opened. Due to the negative pressure generated by the submersible pump 20 when the water is removed, water is again drawn into the reservoir 1 via the inlet 6. Thus, the water suction device is operated exclusively by means of the submersible pump 20. Due to a filter device 26 assigned to the inlet 6 and comprising the filter housing cover 3, the filter housing 4, the sieve insert 5 and possibly further filter inserts, the water suction device is particularly suitable for Cleaning a swimming pool, pond, fountains and the like, since the contaminated water sucked in by the filter device 26 can be freed of dirt particles through the drain 19 as purified water to the swimming pool or the like.
  • the suction nozzle 10 inserted into the cover 2 of the storage container 1 is, in addition to the outlet 13, a connection 27 for a further or alternative suction device 9, wherein in the connection 27 a third shut-off valve 29 of the valve device 16 designed as a check valve 28 is used.
  • a third shut-off valve 29 of the valve device 16 designed as a check valve 28 is used.
  • the housing 32 is assigned a plug 34 for connection to the mains and a socket 35 for connecting further electrical devices.
  • the housing 33 has a key switch 36.
  • an aspirator 37 driven by an electric motor is provided as the suction device 9 and is connected to the connection 27 of the suction nozzle 10 via a hose 38.
  • a cable 39 of the suction device 37 is plugged into the socket 35 connected to the control unit 33.
  • the water suction device is started up by acting on a switch 40 assigned to the control unit 33, which is housed in the housing 32.
  • the suction device 37 When the storage container 1 is empty, the suction device 37 is first put into operation and the air present in the storage container 1 is sucked out through the opened water protection device 12 and the open check valve 28 via the hose 38, so that a negative pressure is created in the storage container 1, through which the Check valve 14 in the outlet 13 of the intake manifold 10 and the check valve 17 in the outlet 19 are closed. Then the medium to be recorded, such as water, water-air mixture, sludge or the like, is sucked in via the suction hose connected to the inlet 6 and reaches the storage container 1 via the filter device 26 until the medium reaches a fill level in the area of the upper fill level sensor 30.
