Definitions

  • the invention relates to a suction device for cleaning purposes a closable suction inlet, a suction outlet and a collecting container arranged between them, with a suction line from the suction outlet a suction unit is connected, the suction line is closable by means of an outlet valve and wherein the side of the filter facing away from the suction inlet one with a Supply valve lockable external air supply arranged is.
  • Such devices are used, for example, as industrial vacuum cleaners used. After some operating time, there is a heavy contamination of the filter, so that filter cleaning becomes necessary. This is done for simple devices by tapping the filter, for example with the help of a mechanical scraper.
  • EP-B1-0 197 036 proposes a vacuum cleaner to use two separate filters and a device to reverse the air circulation in one of the filters. For this purpose, the suction line is closed, and the through air drawn in through one filter flows through the other filter in the reverse flow direction, so that cleaning this filter is done. This requires a structurally complex Design, also need two separate filters be provided.
  • DE-C1-41 38 223 proposes filter cleaning perform in several steps, one each Part of the filter covered by an external air supply is so that this filter section in the counterflow direction flowed through and thus cleaned.
  • the cleaning of the whole Filters is quite time consuming, it also requires the external air supply that can be placed on individual sub-areas considerable design effort.
  • the German Auslegeschrift 12 45 550 proposes to achieve a filter cleaning in that at first running suction unit the suction inlet is closed, so that a negative pressure is created in the collecting container. Subsequently the suction unit is switched off and / or the outlet valve closed. A supply valve is then opened and Via an external air supply outside air into the space between the filter and exhaust valve let in.
  • the handling designed proves to be quite complex and prone to operating errors, moreover, there is not sufficient in all cases Filter cleaning.
  • a suction device is described in US Pat. No. 4,277,265, which uses a bag-shaped filter, that is pressed together during filter cleaning. For this are in a collection container holding the filter Inlet valve and a closable with a supply valve External air supply is provided, the inlet valve mechanically is coupled to the supply valve. If the inlet valve is closed, so the supply valve is opened and at the same time External air flows on the side of the filter facing away from the filter Collecting container in the collecting container. This will make it bag-shaped filter compressed, the im Any air left over when the intake valve closes the suction outlet can escape. It is with this suction device required that during filter cleaning, i.e. when open Supply valve and incoming external air, the Suction unit with the collection container in flow connection stands. The filter cleaning is therefore with a high load connected to the suction unit.
  • suction device a closing an inlet valve associated with the suction inlet and / or opening the supply valve with the Closing the exhaust valve coupling valve coupling unit includes.
  • the valve coupling unit makes handling easier of the suction device during filter cleaning. This is done by that the filter in the counterflow direction with external air is flowed through, which is fed to the filter via the external air supply becomes. In order to prevent the outside air from entering the Suction unit is sucked, the connection between the collecting container and suction unit are interrupted by the Exhaust valve is closed. In addition, the suction inlet be closed so that the external air due to the in the collection container prevailing negative pressure in the collecting container is sucked in. This can cause the suction inlet to be closed done that the user the suction inlet for example with your hand or by using a Inlet valve associated with suction inlet closes. Via the valve coupling unit are in the embodiment of the invention of the suction device, the valves at least partially with one another coupled so that the handling of the suction device easier designed and operating errors avoided.
  • the suction device comprises an inlet valve
  • this can be done according to of the present invention via the valve coupling unit be coupled to the exhaust valve such that the one Valve, for example the inlet valve, closed automatically when the user switches the other valve, e.g. the Exhaust valve closes. He then only needs the supply valve open to effect filter cleaning.
  • the supply valve can also be coupled to the exhaust valve so that, for example the external air supply is opened automatically when the exhaust valve passes into its closed position, or that conversely the exhaust valve closes when the outside air supply is opened.
  • a coupling can also exist if no inlet valve is provided, the user Instead, cover the suction inlet by hand, for example.
  • the suction device is easier to handle when Filter cleaning. Is the supply valve with the outlet valve coupled, so it is also avoided that erroneous after opening the supply valve, the outlet valve is closed becomes.
  • suction device is a Includes inlet valve and both this and the supply valve coupled to the outlet valve via the valve coupling unit are. The user then only has to operate one valve. The other valves are opened and closed then automatically.
  • Negative pressure is usually due to existing leaks in the collection container after a relatively short time Time reduced when the exhaust valve is closed and thereby the collection container is separated from the suction unit.
  • the valve coupling unit the supply valve at the latest after a delay of about 3 seconds Closing the exhaust valve opens.
  • the supply valve is inside this time interval open, it is sufficient in the collection container prevailing negative pressure even with manufacturing technology conditional usual leaks of the collecting container to ensure thorough filter cleaning.
  • the coupling between the inlet and outlet valve can be different Types, for example mechanical, electromagnetic, hydraulic or pneumatic.
  • the coupling of the outlet and supply valve can also be in be configured in many ways, for example one electromagnetic or hydraulic coupling provided his. With an inexpensively producible configuration of the Invention is provided that the outlet and the feed valve are mechanically coupled.
  • outlet and the feed valve are pneumatic are coupled.
  • the exhaust valve on the external air supply controlling pressure sensor is arranged.
  • the one with the Opening the supply valve pressure increase in the External air supply is registered by the pressure sensor, which is due to the pressure increase closes the outlet valve.
  • the external air supply can open into the suction line Include supply line.
  • Supply valve one against the action of a spring in its open Position includes movable valve body. This will ensures that in the operating phases in which no filter cleaning is necessary, the valve body of the supply valve by the spring force in its closed position is held.
  • Valve body of the supply valve can be moved along the supply line is and in its open position one in the Supply line arranged opening, which he in his closed position covered.
  • the outlet valve one in its closed Position immersed in the suction outlet and this in the open position releasing valve body.
  • the suction inlet is closed during filter cleaning, after opening the feed valve is due of the negative pressure prevailing in the collecting container.
  • Immerses the valve body of the exhaust valve in his closed position in the suction outlet ensures that from the collection container during filter cleaning no dust or dirt escapes.
  • the invention provided that the filter the suction outlet is arranged adjacent. This is also why Advantage, as this allows the filter when immersing the valve body the exhaust valve in the suction outlet mechanically shaken can be, so that in addition to the flow through the foreign air in the counterflow direction through the filter caused cleaning effect mechanically tapped the filter becomes.
  • a structurally simple configuration results from that the valve body of the exhaust valve along the supply line is movable.
  • the Exhaust valve body towards its open Position is spring-loaded. This ensures that the outlet valve is in the operating phases of the suction device, in which no cleaning is required, in the open Position.
  • valve body of the exhaust valve along one in the suction line immersed end portion of the supply line is displaceable and from flowing through the suction outlet Airflow is held in its open position.
  • dirt and Air laden with dust particles from the suction unit into the collection container sucked in.
  • the air then flows through it Filter and enters the suction line via the suction outlet.
  • An air flow thus forms at the suction outlet the valve body of the exhaust valve in the operating phases, in where no filter cleaning is necessary, in its open Holds position. Additional elements to the valve body to keep the exhaust valve in its open position, are therefore not necessary.
  • the invention provides that the valve body of the supply valve in one piece with the valve body of the exhaust valve connected is. There is therefore a mechanical one Coupling of the two valves, with a shift of one Valve body a displacement of the other valve body due to the one-piece design.

  • a particularly favorable construction of a suction device results if the suction inlet opens into the collection container Intake port and the inlet valve as in its closed Position formed through the suction port slider are.
  • the suction inlet is connected to a suction hose Suction nozzle of the suction device in connection. It is an advantage if the inlet valve is arranged on the suction nozzle, because thereby a particularly good accessibility of the inlet valve results for the user and he therefore does this easily and conveniently can operate.
  • Suction device is provided that the suction device after closing the suction inlet, the supply valve opens Control unit includes. The handling of the suction device at the The filter is thus cleaned by the suction inlet is closed. The feed valve is then opened automatically by the control unit provided and the closing of the exhaust valve by the valve coupling unit.
  • the control can, for example, be time-dependent, so that the control unit the supply valve after a defined Time interval after closing the suction inlet opens. During this time interval, due to the ongoing Suction unit in the collecting container an increased negative pressure generated after the time interval, for example after a maximum of about 5 seconds, the supply valve automatically opened by the control unit.
  • control unit depending on the in the collection container prevailing pressure between the suction inlet and filter Control piston includes.
  • the control piston thus acts as a pressure sensor that measures the pressure in the collection container detected.
