Definitions

  • the invention relates to a suction device for cleaning purposes with a lockable suction inlet, a suction outlet and a filter arranged between them, which is connected to a suction unit via a suction line emanating from the suction outlet, the suction line being closable by means of an outlet valve and wherein On the side of the filter facing away from the suction inlet, an external air supply which can be closed with a supply valve is arranged.
  • Devices of this type are used, for example, as industrial vacuum cleaners. After some operating time, the filter becomes very dirty, so that filter cleaning is necessary. In simple devices, this is done by tapping the filter, for example with the help of a mechanical scraper.
  • EP-B1-0 197 036 it is proposed to use two separate filters in a vacuum cleaner and a device for reversing the air circulation in each of the filters. For this purpose, the suction line is closed, and the air drawn in through one filter flows through the other filter in the reverse flow direction, so that this filter is cleaned. This requires a structurally complex design, and two separate filters must also be provided.
  • DE-Cl-41 38 223 proposes to carry out the filter cleaning in several steps, in each case a partial area of the filter being covered by an external air supply, so that this partial filter area is in the counterflow direction flowed through and thus cleaned.
  • the cleaning of the entire filter is very time-consuming, and the external air supply which can be placed on individual sub-areas requires considerable construction effort.
  • German Auslegeschrift 12 45 550 it is proposed to achieve filter cleaning by first closing the suction inlet while the suction unit is running, so that a negative pressure is created in the collecting container. The suction unit is then switched off and / or the outlet valve is closed. A supply valve is then opened and outside air is admitted into the space between the filter and the outlet valve via a supply of external air. The handling is therefore quite complex and prone to operating errors, and in addition, there is not sufficient filter cleaning in all cases.
  • the suction device comprises a valve coupling unit which couples the closing of an inlet valve assigned to the suction inlet and / or the opening of the supply valve with the closing of the outlet valve.
  • the valve coupling unit makes the suction device easier to handle when cleaning the filter. This takes place in that foreign air flows through the filter in the counterflow direction and is supplied to the filter via the external air supply.
  • the connection between the collecting container and the suction unit must be interrupted by closing the outlet valve.
  • the suction inlet must be closed so that the outside air is sucked into the collecting container due to the negative pressure prevailing in the collecting container.
  • the suction inlet can be closed by the user covering the suction inlet by hand, for example, or by closing an inlet valve which may be associated with the suction inlet.
  • the valves are at least partially coupled to one another so that the handling of the suction device is simpler and operating errors are avoided.
  • the suction device comprises an inlet valve
  • this can be coupled to the outlet valve via the valve coupling unit such that one valve, for example the inlet valve, is closed automatically when the user uses the other valve, for example the exhaust valve closes. He then only has to open the feed valve in order to clean the filter.
  • the supply valve can also be coupled to the exhaust valve, so that, for example, the external air supply is automatically opened when the exhaust valve changes to its closed position, or conversely the exhaust valve closes when the external air supply is opened.
  • Such a coupling can also be present if no inlet valve is provided, instead the user covers the suction inlet by hand, for example.
  • the suction device is easier to handle when cleaning the filter. If the feed valve is coupled to the outlet valve, it is also avoided that the outlet valve is erroneously closed only after the feed valve has opened.
  • suction device comprises an inlet valve and both this and the supply valve are coupled to the outlet valve via the valve coupling unit.
  • the user then only has to operate one valve.
  • the other valves are then opened and closed automatically.
  • the negative pressure which forms in the collecting container due to the suction unit is generally reduced after a relatively short time due to the presence of leaks in the collecting container when the outlet valve is closed and the collecting container is thereby separated from the suction unit.
  • the valve coupling unit the supply valve at the latest opens after a delay of approximately 3 seconds after the exhaust valve closes. If the supply valve is opened within this time interval, the negative pressure prevailing in the collecting container is sufficient even in the case of the usual leaks in the collecting container due to the production technology in order to effect thorough filter cleaning.
  • a particularly effective filter cleaning can be achieved in that the valve coupling unit opens the supply valve essentially simultaneously with the closing of the outlet valve. In this case, even if there are leaks in the collecting container, the entire negative pressure for filter cleaning is used, which was formed in the collecting container before the connection between the collecting container and the suction unit was interrupted.
  • the coupling between the inlet and outlet valve can take place in various ways, for example mechanically, electromagnetically, hydraulically or pneumatically.
  • the coupling of the outlet and supply valve can also be designed in many ways, for example an electromagnetic or hydraulic coupling can be provided.
  • an embodiment of the invention which can be produced at low cost, it is provided that the outlet valve and the feed valve are mechanically coupled.
  • outlet and the feed valve are pneumatically coupled.
  • a pressure sensor controlling the exhaust valve is arranged on the external air supply.
  • the one with the Opening the supply valve increases the pressure in the external air supply is registered by the pressure sensor, which closes the outlet valve due to the pressure increase.
  • the pressure sensor is designed as a sliding element which is held displaceably on the external air supply and is displaceable as a function of the pressure prevailing in the external air supply. If the supply valve is opened, the pressure in the external air supply increases and the sliding element is displaced. This closes the exhaust valve.
  • the external air supply can comprise a supply line that merges into the suction line.
  • the supply valve comprises a valve body which can be moved into its open position against the action of a spring. This ensures that the valve body of the supply valve is held in its closed position by the spring force in the operating phases in which no filter cleaning is necessary.
  • valve body of the supply valve is displaceable along the supply line and in its open position exposes an opening arranged in the supply line, which it covers in its closed position.
  • the outlet valve includes a valve body which plunges into the suction outlet in its closed position and releases it in the open position.
  • the suction inlet is closed during filter cleaning close, after opening the supply valve, external air is sucked in due to the negative pressure prevailing in the collecting container. If the valve body of the outlet valve plunges into the suction outlet in its closed position, this ensures that no dust or dirt escapes from the collecting container during filter cleaning.
  • the filter is arranged adjacent to the suction outlet. This is also advantageous because it allows the filter to be mechanically shaken when the valve body of the outlet valve is immersed in the suction outlet, so that in addition to the cleaning action caused by the flow of outside air in the counterflow direction through the filter, the filter is knocked off mechanically.
  • a structurally simple configuration results from the fact that the valve body of the outlet valve is displaceable along the feed line.
  • valve body of the exhaust valve is spring-loaded in the direction of its open position. This ensures that the outlet valve is in the open position in the operating phases of the suction device, in which no cleaning is required.
  • valve body of the outlet valve is displaceable along an end section of the feed line which plunges into the suction line and flows through the suction outlet. air flow is held in its open position.
  • air laden with dirt and dust particles is sucked into the collecting container by the suction unit. The air then flows through the filter and enters the suction line via the suction outlet. An air flow thus forms at the suction outlet, which holds the valve body of the outlet valve in its open position in the operating phases in which no filter cleaning is necessary. Additional elements for holding the valve body of the exhaust valve in its open position are therefore not necessary.
  • valve body of the supply valve is integrally connected to the valve body of the outlet valve. There is thus a mechanical coupling of the two valves, a displacement of one valve body resulting in a displacement of the other valve body due to the one-piece design.
  • the inlet valve can be arranged at the suction inlet.
  • suction inlet is designed as a suction nozzle that flows into the collecting container and the inlet valve is designed as a slider reaching through the suction nozzle in its closed position.
  • the suction inlet is connected to a suction nozzle of the suction device via a suction hose. It is advantageous if the inlet valve is arranged on the suction nozzle, since this makes the inlet valve particularly accessible results for the user and he can thus operate it easily and comfortably.
  • the feed valve can be operated.
  • the supply valve can be actuated mechanically, for example by hand.
  • the suction device comprises a control unit which opens the supply valve after the suction inlet has been closed.
  • the handling of the suction device during filter cleaning is thus done by closing the suction inlet.
  • the supply valve is then opened automatically by the control unit provided and the outlet valve is closed by the valve coupling unit.
  • the control can be time-dependent, for example, so that the control unit opens the supply valve after a defined time interval has elapsed after the suction inlet has been closed. During this time interval, an increased negative pressure is generated in the collecting container due to the running suction unit. After the time interval has elapsed, for example after a maximum of about 5 seconds, the supply valve is automatically opened by the control unit.
  • a particularly effective filter cleaning is ensured in that the control unit opens the supply valve when a defined negative pressure is reached in the collecting container between the suction inlet and the filter.
  • the negative pressure prevailing in the collecting container in front of the filter is therefore decisive for the opening of the supply valve.
  • a heavy contamination has the consequence that the suction effect of the suction unit prevailing in the collecting container is reduced, so that a longer time interval is necessary in order to achieve the increased negative pressure desired for a particularly effective filter cleaning after the suction inlet is closed. If, on the other hand, there is only slight contamination of the filter, the desired negative pressure in the collecting container is reached shortly after the suction inlet is closed.
  • control unit comprises a control piston which can be displaced depending on the pressure prevailing in the collecting container between the suction inlet and the filter.
  • the control piston thus acts as a pressure sensor which detects the pressure prevailing in the collecting container.
  • the control of the supply valve can take place in that the valve body of the supply valve can be moved into its open position depending on the position of the control piston. If the suction inlet is closed, the pressure in the collecting container is lowered and the control piston is displaced. This displacement serves as a signal for the valve body of the supply valve, which is moved into its open position when the displacement of the control piston has reached a desired extent in accordance with the negative pressure prevailing in the collecting container.
