Definitions

  • the invention relates to a mobile cleaning device for liquids, such as water, with a suction device having a suction connection for the liquid to be cleaned, a wet filter arranged in the liquid flow and defining a filter inlet side and a pressure connection and, for example, a pump-containing return device for the cleaned liquid, the Suction device and the return device each have an inlet on the suction side and both inlets are connected to an air-containing vacuum chamber to be evacuated by the suction device, into which the suction connection opens, and the return device is also provided in the flow path of the liquid after the wet filter.

  • GB-A-1 336 117 has disclosed a cleaning device for cleaning the cooling liquid of machine tools, in which a horizontal boiler is divided into two chambers, namely a filter chamber and a storage chamber for the cleaned liquid. Above the liquid level, the suction-side inlet of a suction blower is connected to the storage chamber and is indirectly connected to the filter chamber via a pipeline passing through the intermediate wall between the two chambers. Below this pipeline, the two chambers are connected to one another via a check valve so that cleaned liquid can only get from the filter chamber into the storage chamber. The lower end of the suction pipe of a water pump protrudes into the storage chamber, which receives a pump rotor which is connected to a motor outside the boiler.
  • suction-side inlet which serves to evacuate the boiler, opens into the storage chamber, this inlet is located relatively far from the wet filter and from the suction port for the liquid to be cleaned, this suction-side inlet also being arranged downstream of the filter outlet side of the wet filter. This results in a relatively poor efficiency, a space-consuming construction and only a delayed response of the suction effect when commissioning.
  • the invention is based on the object of providing a cleaning device of the type mentioned at the outset which, even with a compact design, has high performance and low susceptibility to failure.
  • a cleaning device of the type mentioned according to the invention in that the suction-side inlet of the suction device is assigned to the filter inlet side of the wet filter.
  • the suction device does not need to suck the liquid to be cleaned through the wet filter, so that it works practically irrespective of its degree of soiling and very quickly creates a sufficiently high vacuum in the vacuum chamber when it is started up.
  • This also protects the suction device. Since the contaminated water is sucked in with a high liter output without having to pass through any moving machine parts and then fed to a possibly very large-area filter, the wet filter can be set to a very fine filtration by the design according to the invention without impairing the throughput.
  • the return device is only exposed to the filtered water, so that it is not subject to interference or damage from dirt.
  • the cleaning device according to the invention is particularly suitable for swimming pools or the like.
  • swimming pools in particular the bottom of swimming pools, two different types of devices are mainly used.
  • the type of device of the type mentioned above usually has a self-propelled rotor driven by an electric motor, which runs off the bottom of the swimming pool and sucks in water with loosened dirt via a pump and presses it through a pressure or outlet-side wet filter in the form of, for example, a filter bag and return the filtered water back to the swimming pool.
  • the pump is both a component of the suction device and the return device for the cleaned liquid.
  • the other type of device generally has a suction nozzle which can be guided with a rod or tube and which is connected via a hose to the surface suction of the swimming pool, namely the so-called “skimmer”.
  • the sucked-in dirt is retained in the swimming pool filter stationary associated with the swimming pool, which leads to very rapid contamination, for example with leaves, of the filter. Furthermore, there are very high backwash losses in the swimming pool water because these filters have to be cleaned by backwashing and removing the backwash water.
  • the coarse dirt accumulating when cleaning the swimming pool also leads to unsanitary contamination of the swimming pool filter, which is constantly in communication with the swimming pool water.
  • a very compact design of the subject matter of the invention is obtained if the suction opening of the return device and the vacuum chamber are provided one above the other in a common main chamber, in particular a boiler standing upright due to its vertical extension, the vacuum chamber in particular due to the pressure-tight space above the liquid level of a liquid intermediate store in the main chamber is formed.
  • the intermediate store can be used in a simple manner to prevent the return device from running dry, although a pump can also be provided which has good dry-running properties. Since the intermediate store communicates with the vacuum chamber, when vacuuming filtered water from the intermediate store, the negative pressure in the vacuum chamber and thus the suction power of the suction device are increased accordingly.
  • suction device and the feedback device by separate units, which are preferably driven by separate motors, for example electric motors.
  • separate motors for example electric motors.
  • a separate motor suction fan and a motor pump are each structurally combined with the boiler.
  • the pump can be arranged in a simple manner, for example in the form of a submersible pump, below the vacuum chamber, preferably on the bottom of the main chamber, so that it contributes to a low position of the center of gravity of the cleaning device.
  • At least one suction opening is expediently located in the immediate vicinity of the floor and the pressure line is led out of the main chamber in a pressure-tight manner, so that negative pressure losses in the negative pressure chamber are avoided and the intermediate store can be at least almost completely emptied by the pump.
  • the delivery rates of the suction device and the feedback device can be coordinated with one another in a particularly simple manner in that the feedback device is controlled as a function of the liquid level in the cleaning device, preferably with a float switch. If the return device is matched to the suction device in such a way that the wet filter lies above the highest liquid level, the water can flow through the wet filter unhindered, and in addition it is avoided that the dirt retained in the wet filter is suspended by the filtered water.
  • the pump is expediently designed in such a way that it has a somewhat higher delivery capacity than the suction fan, so that it is switched off automatically several times during operation, for example by the float switch. While the pump is not delivering, a return suction via the outlet of the return device is prevented by the check valve mentioned.
  • the suction device is arranged on the upper side of the vacuum chamber and preferably detachably closes the wet filter and / or the vacuum chamber at an upper opening with the suction side, in particular the suction device providing a boiler lid and / or a ring clamp for forms the wet filter.
  • the suction device can also be placed as a suction head or boiler lid on another, not a return device, but rather as a buffer tank for dust-containing boilers and thus form a high-performance vacuum or wet vacuum cleaner.
  • the suction nozzle leading into this boiler opens into the boiler such that the filter or filter bag lies between its mouth and the suction side of the suction device, so that dirt does not flow through the suction device.
  • the suction connection expediently opens below the suction device, in particular directed obliquely downwards, into the vacuum chamber, wherein it is preferably formed by a nozzle inserted radially into the boiler wall, so that there is practically no risk of water entering the Suction device is sucked.
  • Both the suction device and the return device thus work in unpolluted medium, namely the suction device with air and the return device with filtered water.
  • the Suction opening of the suction device is assigned a float valve, which preferably has a float standing in the axis of the boiler, which is guided in a support cage or the like for the wet filter, which engages in the wet filter and is structurally combined with the suction device, and in particular in the initial position with its valve closing member at approximately the height of the suction port adjacent to its circumference. Due to the correspondingly lightweight and large-volume design of the float, the swimmer responds quickly even to small amounts of water. The fact that a support cage is provided for the wet filter, then this can be kept in a simple manner in a wide area despite the low pressure. If this support cage forms part of the boiler lid, it is also effective when another boiler is used.
  • a filter housing in the form of, preferably, a coated textile jacket with a dimensionally stable, perforated base is required to hold the, particularly replaceable or designed as a disposable filter , for example a perforated plate, is provided, which in particular has a lateral opening for the sealed passage through the suction connection.
  • This filter housing which is coated, for example, with a rubber-like plastic and is network-like, supports the wet filter against the impinging contaminated water.
  • the wet filter is filled with dirt, it can be removed from the cleaning device in a simple manner as a container holding this dirt, including the dirt thrown away and replaced by a new wet filter.
  • the wet filter is fastened by clamping its upper, turned-out edge against a profile ring which seals the upper side of the vacuum chamber and which preferably carries the filter housing and / or is stepped radially inward from top to bottom several times. If the boiler lid or the suction device is removed from the boiler, the wet filter is thus freely accessible for removal.
  • the cleaning device has a chassis, which is preferably provided with self-steering trailing wheels, so that it can be driven around the outside of the swimming pool or retightened with a suction hose connected to its suction connection.
  • a sink hose is expediently connected to the outlet of the return device, the outlet-side end of which lies below the water level in the swimming pool.
  • the invention further relates to a wet filter for a cleaning device of the type described, which - in the form of a filter bag or the like.
  • a paper fleece with high hydraulic permeability has a push-through opening in the jacket for the suction connection, which is preferably attached by one on its inside, one elastically limited passage opening for the cuff having suction connection is formed in the form of, for example, a flat, flexible reinforcement.
  • the filter bag or paper tile is bound to be moisture-resistant. After insertion into the filter housing, the filter bag with its through opening is pushed over the suction nozzle of the suction device, so that its mouth lies inside the filter bag.
