Definitions
- the invention relates to a vacuum cleaning device having a dirt collecting container which has a suction inlet and is in flow communication via at least one filter and at least one suction channel with at least one suction unit, and with at least one downstream of the at least one filter in the suction channel opening outside air inlet, which selectively by means of a closing body lockable and is releasable.
- the vacuum cleaning device has at least one filter, which is arranged in the flow path between the dirt collecting container and the suction unit and serves for the separation of solids from the suction flow.
- dirt particles are increasingly deposited on the dirty side of the at least one filter facing the dirt collecting container, so that the filter has to be cleaned after some time.
- the clean side of the filter facing away from the dirt collecting container can be subjected to external air by a closing body releasing at least one outside air inlet opening into the suction channel downstream of the filter.
- Such suction devices are known for example from DE 298 23 411 Ul and DE 10 2005 017 702 Al.
- the closing bodies are in this case designed as a valve disk of a lifting valve, which by means of an electromagnet in a Closed position can be kept in which he shoots the at least one forced air intake. If the power supply of the electromagnet is interrupted, the valve plate lifts off from the forced air inlet, so that extraneous air can suddenly flow into the suction channel and act on the clean side of the filter.
- Saugquelsetti have proven themselves.
- designed as a valve disk of a lift valve closing body for the proper function of the filter cleaning requires considerable space.
- Object of the present invention is to provide a Saugquess réelle of the type mentioned in such a way that the space required for proper filter cleaning space of the closing body can be reduced.
- the suction duct has a Fremd Kunststoffeinlass- wall with at least one forced air inlet and the closing body along the outside of the forced air inlet wall along sliding between the at least one forced air inlet occluding closed position and the at least one forced air inlet releasing release position is reciprocable.
- the installation space of the closing body required for proper filter cleaning can be considerably reduced by the closing body sliding along the outside of the outside air inlet wall which has the at least one outside air inlet.
- the closing body sliding along the outside of the outside air inlet wall which has the at least one outside air inlet.
- the external air inlet wall comprises a plurality of external air inlets, which are released simultaneously by transition of the closing body from its closed position to its release position.
- the vented air inlets are designed slot-shaped and the closing body can be moved from its firing position into its release position transversely to the longitudinal axis of the slot-shaped vented air inlets.
- Such a configuration has the advantage that the closing body only has to perform a relatively small lifting movement in order to be able to completely release all slit-shaped forced air inlets at the same time.
- the external air inlet wall and the closing body are designed plate-shaped. This results in a further reduction of the installation space.
- the closing body can be linearly displaceable along the outside of the external air inlet wall.

- the center may be the pivot axis of the pivotable Defining closing body, which closes the radially extending external air inlets in its closed position and releases it in its release position.
- the external air inlet wall and the closing body are bent in a cylindrical shape. It is advantageous if the closing body is pivotable about the cylinder axis of the forced air inlet wall.
- the closing body rests directly against the forced air inlet wall.
- sealing elements for example O-rings, arranged between the closing body and the forced air inlet wall can be dispensed with.
- the closing body is elastically deformed more strongly than the forced air inlet wall under the effect of the pressure difference between the negative pressure prevailing in the suction channel during operation of the vacuum cleaning device and the outside pressure acting on the closing body.
- the stronger elastic deformability of the closing body causes the closing body is pressed during operation of the Saugquels expertss against the forced air inlet wall, which has a lower elastic deformability.
- the pressing of the closing body against the forced air inlet wall seduces that the foreign air inlets are reliably sealed during the suction operation of the vacuum cleaning device.
- the closing body and the external air inlet wall are made of different materials, wherein the material of the closing body has a greater elastic deformability than the material of the forced air inlet wall.
- the closing body and the external air inlet wall are made of the same material, but wherein the external air inlet wall has a greater dimensional stability than the closing body.
- the outside air inlet wall may have a greater material thickness than the closing body.
- the reinforcing elements ensure that the external air inlet wall has only a very low elastic deformability, so it is designed to be more rigid than the closing body and forms a only slightly bending abutment for the closing body during the suction operation of Saugquels expertss.
- the reinforcing elements are preferably designed as reinforcing ribs molded onto the external air inlet wall.
- At least one reinforcing rib is arranged in each case between adjacent outside air inlets.
- a particularly effective filter cleaning is achieved in an advantageous embodiment in that the outside air inlet wall facing the clean side of the filter.
- the external air inlet wall forms a cover of the filter so that the external air flowing through the external air inlets in the release position of the closing body directly reaches the clean side of the filter and mechanically shakes it. tert, wherein at least a part of the inflowing external air can flow through the filter against the prevailing in the suction operation of Saugtherapies confuses flow direction. The filter can thus be cleaned very effectively.
- the filter is designed as a cartridge filter, in particular, the filter can be configured cylindrical.
- the filter is designed as a flat-fold filter, since thereby the space can be kept low.
- the external air inlet wall covers the flat pleated filter.
- the external air inlet wall can in this case extend over the entire length and over the entire width of the flat pleated filter, so that it can be acted upon on its entire outside with external air.
- the closing body is movable back and forth between its closed position and its release position.
- an electric drive or a pneumatic drive can be used.
- the closing body is electromagnetically movable.
- a solenoid can be used.
- a solenoid may be provided which presses the closing body against the action of a spring force in its release position.
- the solenoid can be on or off by an electronic control system at intervals Several times in a row be energized for automatic filter cleaning.
- the closing body is manually movable.
- Such a configuration is characterized by particularly low production costs.
- the space for the closing body and its drive can be kept very low.
- the closing body is movable by means of a pivot lever.
- the swivel lever can be actuated by the user of the vacuum cleaning device for filter cleaning.
- the closing body against the action of a return spring from its closed position is a release position movable.
- the return spring ensures that the closing body, starting from its release position, can again be reliably moved back into its closed position.
- the return spring may be formed for example as a compression spring.
- the return spring is helical.
- the return spring is arranged on the outer side of the forced air inlet wall.
- the external air inlet wall can have a return, against which the return spring rests. As a result, the space can be additionally reduced.

- Figure 2 is a sectional view of the Saug lenderss advocatess along the line 2-2 in Figure 1;
- Figure 3 is a sectional view of the Saug lenderss expertss along the line 3-3 in Figure 1 and
- Figure 4 is a vertical sectional view of the vacuum cleaning device of Figure 1 during the cleaning of a filter.
- an inventive Saugquess choir 10 is shown schematically with a lower part, which forms a dirt collector 12, and an attachable to the lower part top 14.
- the dirt collector 12 has a suction inlet 16, to the usual manner in the drawing not shown suction hose can be connected, at the free end of a suction nozzle can be held.
- suction hose is connected to a machining tool, for example a drilling machine or a milling unit, so that dust accumulating during operation of the machining tool can be extracted.
- the upper part 14 receives a suction unit 18 with an electric motor 20 and a suction turbine 22.
- the suction unit 18 is arranged lying, d. H. the turbine axis 24 of the suction unit 18 extends horizontally.
- a flat pleated filter 26 is held in the upper part 14, to which a suction channel 28 is connected within the upper part 14.
- the suction channel 28 establishes a flow connection between the dirt collecting container 12 and the suction unit 18.
- Negative pressure can be applied, so that the symbolized in Figure 1 by the arrows 30 suction flow is formed, under the effect of dirt in the dirt collector 12 can be sucked.
- the dirt particles can be separated from the suction flow 30.
- Suction air is sucked from the suction unit 18, which, starting from the dirt collecting container 12, flows through the flat pleated filter 26 in order to reach the suction inlet 32 of the suction unit 18 via the suction channel 28.
- the suction air is sucked axially with respect to the turbine axis 24 and is discharged from the suction turbine 22 in the radial direction.
- the exhaust air duct 34 is arranged below the suction channel 28 in the rear region 38 of the vacuum cleaning device 10 facing away from the suction inlet 16.
- the suction channel 28 has a duct wall in the form of a forced air inlet wall 40, which extends over the entire length and over the entire width of the flat pleated filter 26 and which has a plurality of slot-shaped forced air inlets 42, which are arranged side by side at a constant distance.
- a reinforcing rib 46 is integrally formed on the inside 44 of the external air inlet wall 40.
- the closing body 50 On the outside 48 of the plate-shaped external air inlet wall 40 is a plate-shaped closing body 50 slidably.
- the closing body 50 has a multiplicity of slot-shaped passages 52, which are of identical construction to the outside air inlets 52 of the outside air inlet wall 40.
- the passages 52 are arranged laterally offset from the outside air inlets 42 in the closed position of the closing body 50 shown in FIG. 1, so that the closing body 50 the outside air inlets 42 closes.
- the closing body 50 can be moved against the action of a return spring 54 in the release position shown in Figure 4. In the release position, the passages 52 are aligned with the external air inlets 42.
- the return spring 54 is arranged between the outside air inlet wall 40 and the closing body 50 on the outside 48 of the outside air inlet wall 40. It is supported, on the one hand, on a step 62 of the outside air inlet wall 40 and, on the other hand, on a step 64 of the closing body 50.
- a pivot lever 66 is used, which is mounted pivotably about a pivot axis 68 on the upper part 14 and can be operated by the user of Saugquels confuses 10.
- the pivoting lever 66 is engaged with an actuating pin 70, which is connected in one piece with the closing body 50 and which is arranged below the pivoting lever 66 in the closed position of the closing body 50 shown in FIG. If the pivot lever 66 is actuated by the user, it moves the closing body 50 along the outside 48 into the release position shown in FIG. 4 via the actuating pin 70. If the pivot lever 66 is then released again by the user, then the restoring spring 54 moves the closing body 50 back along the outside 48 into its release position.
- the forced air inlet wall 40 Due to the reinforcing ribs 46, the forced air inlet wall 40 has a considerably higher dimensional stability than the closing body 50.
- the latter is elastically more deformable than the external air inlet wall 40.
- the closing body 50 lying flat against the outer side 48 of the forced air inlet wall 40 undergoes only a very short stroke movement during the transition from its closed position into its release position, which corresponds to half the distance between two adjacent forced air inlets 42.
- the result of the low stroke movement is that the forced air inlets 42 can be completely released within a very short time, so that extraneous air can impact the clean side 56 of the flat pleated filter 26 abruptly in order to effectively clean it. Since there is a negative pressure during the transition of the closing body 50 from its closed position into its release position within the dirt collecting container 12, the abruptly penetrating foreign air is sucked into the dirt container 12 through the flat fold filter 26 to a considerable extent. As a result, the mechanical cleaning of the flat pleated filter 26 is enhanced.
- the user can release the pivot lever 66, as already explained, in which case the closing body 50 is automatically moved under the action of the return spring 54 in its closed position, so that the suction operation of the Saugquess- device 10 are continued again can.
