Definitions

  • the invention relates to a vacuum cleaning device having a dirt collecting container, which has a suction inlet and is in flow connection via at least one filter and at least one suction line with at least one suction unit, and with at least one downstream of the at least one filter in the at least one suction line opening outside air inlet, by means of at least a closure valve is closable, wherein the at least one closing valve has a movable valve body which rests in a closed position to form at least one valve seat forming one or more sealing lines, the at least one sealing line delimiting a surface which in the closed position of the closing valve with a differential pressure is charged.
  • Saugtivsetti can be configured, for example, as a vacuum cleaner or as sweeping vacuum. They have a dirt collecting container, which can be acted upon by one or more suction units with negative pressure, so that forms a suction flow, under the influence of dirt in the dirt collecting container can be sucked.
  • the dirt collector is connected via at least one filter and at least one adjoining suction line with the suction unit in flow communication.
  • the at least one filter makes it possible to separate solids, so for example dirt or dust particles, from the suction flow. During the operation of the vacuum cleaning device, more and more solids accumulate on the filter, so that the filter is an increasing flow resistance and must therefore be cleaned.
  • the at least one filter against the flow direction formed in the suction flow direction can be acted upon by external air, the downstream of the filter can flow into the suction line via the outside air inlet.
  • ambient air can be used as external air or compressed air also stored by the vacuum cleaning device or stored in a reservoir under pressure.
  • the at least one closing valve has a movable valve body which bears tightly against at least one associated valve seat during the suction operation, wherein at least one sealing line is formed between the valve seat and the valve body, along which the outside air inlet is sealed.
  • the at least one sealing line delimits a surface which is subjected to a differential pressure in the closed position of the at least one closing valve.
  • Saugkossmaschine are for example from the DE 298 23 411 U1 in which it is proposed to close the suction inlet for filter cleaning, so that forms a strong negative pressure within the dirt collecting container. Subsequently, a closing valve is then opened, thereby cleaning a filter. It can be achieved by an effective cleaning, but this must be completely interrupted the suction operation. To counteract this disadvantage, is in the DE 199 49 095 A1 proposed to clean only a portion of the filter, so that over another portion of the suction operation can be maintained. Individual sections of the filter are thus cleaned in succession, without the suction must be interrupted. However, the supply of external air in each case only to a portion of the filter requires a structurally complex mechanism for the closing valve.
  • Object of the present invention is to provide a Saugquessêt of the type mentioned in such a way that the at least one closing valve structurally simple design and the at least one filter can be completely cleaned within a short time.
  • the idea flows in that by providing one or more seal lines as long as possible, but which limit the smallest possible area, a strong, abrupt onset of external air flow can be provided during lifting of the valve body from the valve seat within a very short time, so that on the side facing away from the dirt collecting container of the at least one filter, the negative pressure drops abruptly and the filter is flowed through in the counter-current direction with external air.
  • the sudden pressure increase has the consequence that the filter is mechanically shaken and cleaned, whereby the cleaning can be done within a very short time.
  • the total length of all sealing lines is chosen to be significantly larger than the circumference of a circular area whose surface area corresponds to the area of the surface bounded by the sealing lines.
  • the ratio between the square of the total length of all sealing lines and the size of the total of the sealing lines limited area is according to the invention at least 25 and is thus at least twice as large as in the case that there is only one seal line surrounding a closed circular area whose circumference of the Sealing line is defined.
  • the ratio of the square of the length of the sealing line and the size of the circular area gives a value of approximately 12.5, namely four times the number ⁇ (3.14).
  • the area delimited by the at least one sealing line denotes that area which, in the closed position of the closing valve, is acted on by the pressure difference which forms via the closing valve.
  • This surface is delimited by the at least one sealing line, and according to the invention it is provided that, when providing the longest possible sealing line, the area subjected to the differential pressure is chosen as small as possible. Since the surface acted upon by the differential pressure determines the force with which the closing valve is acted upon in its closed position, the mechanical load of the closing valve can be reduced by providing the smallest possible area. This in turn has the consequence that the closing valve may have a small size, and yet on the at least one, as long as possible selected sealing line when opening the closing valve, a strong external air flow can be provided for cleaning the filter.
  • the square of the total length of all sealing lines amounts to at least 50 times, preferably more than 100 times, the total size of all the surfaces delimited by the sealing lines.
  • the at least one closing valve may have a single sealing line, for example a star-shaped or in the form of the edge of a clover designed seal line with alternating positive and negative curvature.
  • the at least one closing valve has a plurality of sealing lines in the form of closed sealing sections.
  • two sealing sections can be used which define an outer edge and an inner edge of a surface acted upon by the differential pressure.
  • the closed sealing sections can be arranged side by side. Preferably, however, the sealing sections form nested sealing rings. Preferably, the sealing rings are arranged concentrically with each other. For example, four sealing rings can be used, which are arranged concentrically to each other, wherein each two sealing rings define an annular, acted upon by the differential pressure surface. In this case, the total of the sealing lines limited area results from the sum of the two annular surfaces.
  • the sealing rings can be arranged over their entire circumference at a uniform distance from each other, but it can also be provided that touch individual sealing rings.
  • the sealing sections are designed to be round and form, for example, an oval or a circle.
  • sealing line is preferably arranged in one plane.
  • the individual sealing lines are arranged in different planes, for example, in staggered or tilted planes.
  • the valve body on a valve disc which is tightly applied to the at least one valve seat with the interposition of at least one sealing line defining a sealing element.
  • the valve disk can be formed very flat, so that the closing valve requires only a very small space.
  • valve disk has at least one, preferably annular passage opening, which is delimited by one or more sealing elements in the closed position of the valve disk.
  • Such a configuration has the advantage that, when lifting the valve disk from the valve seat, external air can flow into the suction line laterally next to the valve disk, but also through the at least one passage opening of the valve disk. Even if the valve plate lifts only slightly from the valve seat, already a strong external air flow can be achieved. This not only has the advantage that only a small range of motion for the valve disc must be ensured, but this has the advantage that even a very short opening movement is sufficient to abruptly act on the at least one filter with external air and thus an effective To achieve cleaning.
  • the at least one valve seat has a plurality of passage openings, which are each delimited by at least one sealing element in the closed position of the valve disk. It can be provided, for example, that the at least one valve seat has two concentrically arranged annular through openings comprises, on the lifting of the valve disk from the valve seat external air can flow into the suction line.
  • the valve body may be pivotably mounted on the at least one valve seat or on a device-fixed part. It is particularly advantageous, however, if the valve body is held displaceably, in particular it can be provided that the valve body is held displaceably in a guide.
  • the guide is cylindrical in an advantageous embodiment, because this gives the possibility to rotate the valve body about the cylinder axis of the guide, without thereby affecting the opening and closing movement of the valve body.
  • the at least one closing valve has a guide sleeve into which a guide receptacle dips.
  • the guide sleeve can be arranged on the valve body, preferably the guide sleeve is integrally connected to the valve body.
  • valve body is acted upon by a spring with a closing force.
  • the spring moves the opening when the closing valve from the valve seat lifting valve body back into its closed position as soon as the negative pressure in the suction line downstream of the at least one filter is degraded by the action of the suction unit.
  • the suction unit is in fact during the filter cleaning with the at least one filter in flow communication, so that the inflowing via the closing valve in the suction line foreign air, which briefly acts on the filter in the counterflow direction is sucked from the suction unit.
  • In the closed position ensures the spring for a reliable fixation of the valve body.
  • the spring absorbs the energy of the valve body, brakes it and accelerates it back to its closed position.
  • the spring may be designed in several parts, in particular in two parts, wherein a longer spring part may have a lower spring constant than a shorter spring part.
  • the shorter spring part with the higher spring constant limits the opening travel of the valve body and thus also the ingress of foreign air.
  • a single spring is used, which preferably has a non-linear characteristic, so that the movement of the valve body at the beginning is only slightly and then more inhibited.
  • a very strong pressure surge can be achieved by which the at least one filter can be cleaned in a very short time.
  • the valve body is held by a magnetic holder in the closed position.
  • a magnetic holder for example, at least one permanent magnet can be used, which reliably holds the valve body in its closed position in the case of pressure differences as they occur during the proper suction operation at the at least one closing valve. If the pressure difference is increased for filter cleaning, the magnetic holder releases the valve body, which then lifts off from the valve seat, so that external air can flow in.
  • the pressure difference can be increased, for example, by the fact that the negative pressure within the dirt collecting container is increased, for example by closing the suction inlet or a suction hose connected to this. Alternatively or additionally, the pressure difference can be increased by the fact that external air with overpressure the at least one closing valve is supplied.
  • the vacuum cleaning device may have a pressure accumulator which is filled with a compressor. If external air is released from the pressure accumulator, then the overpressure exerted on the valve body exerts an increased force in the opening direction, which force can no longer be compensated by the magnet holder, so that the at least one closing valve opens. If the supply of pressurized external air is interrupted, then the pressure builds up, and under the action of the magnetic force, possibly supported by the action of a closing spring, the valve body goes back to its closed position.
  • the magnet holder comprises an electromagnet. This allows an electrical control of the magnetic holder such that the closing valve maintains its closed position, as long as the solenoid is energized. If the power supply is interrupted, the closing valve opens abruptly.
  • the electromagnet as an electro-adhesive magnet.
  • Such Elektrohaftmagente are characterized by a very low magnetic remanence, so that when interrupting the power supply virtually no residual magnetic field is present and therefore the valve body can lift off the valve seat in a very short time.
  • the at least one closing valve is mechanically actuated. It is advantageous, however, if it is electronically operable.
  • the pressure difference that forms via the filter is detected by means of pressure sensors. The greater the pressure difference, the greater the flow resistance of the filter, and when a predetermined value for the pressure difference is exceeded, the at least one closing valve can be actuated by means of control electronics.
  • a time-controlled actuation of the at least one closing valve is advantageous. It can be provided that it can be actuated with different time intervals. In particular, after a plurality of shorter time intervals, a further actuation may be provided only after a longer time interval. However, effective filter cleaning can also be achieved with filter cleaning at constant time intervals.
  • the at least one filter is preferably designed as a folded filter, for example in the form of a filter cartridge or a flat pleated filter.
  • the vacuum cleaning device may have a plurality of filters, but it has proved to be particularly advantageous if the vacuum cleaning device comprises a single filter.
  • the filter can be acted upon by external air simultaneously by opening all closing valves over its entire surface.
  • the inventive design of the vacuum cleaning device makes it possible to abruptly increase the negative pressure in the suction line in the region adjacent to the at least one filter, and then the negative pressure is reduced again within a very short time due to the effect of the at least one suction unit.
  • the valve body can momentarily remain in an open position in order then to change over again into its closed position.
  • the valve body is continuously movable back into its closed position via its open position. In such an embodiment, the valve body performs a continuous movement when opening the closing valve without it remains in its open position.
  • valve body is greatly accelerated when opening the closing valve and then braked again so that it reverses its direction of movement and then its closed position occupies.
  • the entire movement of the valve body starting from its closed position on the open position back into the closed position can be done in fractions of a second.
  • the at least one filter is acted upon by the closing valve for less than 200 ms, in particular for less than 100 ms, with external air.
  • Such loading does not result in any appreciable interruption of the suction operation for the user, but due to the provision of a very long seal line for the at least one closing valve, it results in effective cleaning of the filter.
  • the at least one filter can be acted on by means of the at least one closing valve while maintaining a negative pressure in the mouth region of a suction hose opening into the suction inlet with external air. If the at least one closing valve is opened, the pressure on the side of the filter facing away from the dirt collecting container abruptly increases and is then reduced again. The sudden increase in pressure causes an effective cleaning of the filter, but since it is degraded by the at least one suction turbine immediately again, it does not lead to a complete interruption of the negative pressure in the mouth region of the opening into the suction inlet suction hose. Rather, a quasi-continuous suction operation can be maintained.
  • the negative pressure in the suction hose at a distance of 3 cm from the suction inlet at most for 150 ms below 40% of the value formed when the closing valves are closed is usually a standard hose with an inside diameter of 35 mm and a length of 2.5 m is connected.
  • a negative pressure forms in the suction hose and in the dirt collecting container, the negative pressure in the suction hose at a distance of 3 cm from the suction inlet, for example, about 50 mbar, if no tool is connected to the free end of the suction hose, the free end of the suction hose so it is open.
  • the at least one closing valve for filter cleaning is opened for a short time, then the negative pressure drops briefly to a value of less than 20 mbar at the designated point, but at the latest after 150 ms the negative pressure again exceeds the value of 20 mbar and then approaches the original one again Value of 50 mbar.
  • the negative pressure at the designated point for less than 100 ms, in particular for about 50 to about 80 ms drops below a value of 40% of the forming at closed closing valves value.
  • a vacuum cleaning device in the form of a vacuum cleaner 10 is shown schematically with a lower part, which forms a dirt collecting container 12, on which an upper part 14 is placed, which receives a suction unit 16.
  • the dirt collecting container 12 has a volume of up to 80 l, preferably a volume of about 30 l to about 80 l. It comprises a suction inlet 18, to which a suction hose 20 can be connected, at the free end, which is not shown in the drawing to achieve a better overview, a suction nozzle can be connected.
  • the suction hose 20 is connected to a machining tool, for example a drilling unit or a milling unit, so that dust accumulating during operation of the machining tool can be sucked off.
  • the upper part 14 forms a suction outlet 22 for the dirt collecting container 12, wherein at the suction outlet 22, a pleated filter 24 is held, to which a suction line in the form of a suction channel 26 connects, via which the pleated filter 24 is in flow connection with the suction unit 16.
  • the dirt collecting 12 can be acted upon by the suction unit 16 with negative pressure, so that a in FIG. 1 symbolized by the arrows 28 Saugströmung forms, below their effect dirt can be sucked into the dirt collector 12.
  • the fold filter 24 the dirt particles from the suction flow 28 can be deposited.
  • a closing valve 30 is arranged in the upper part 14, which in FIG. 2 is shown enlarged. It comprises a stationary in the upper part 14 arranged valve holder 32 which forms a valve seat and cooperates with a valve body in the form of a valve plate 34.
  • the valve disk 34 is acted upon by a closing spring 36 with a non-linear characteristic in the direction of the valve holder 32 with a closing force.
  • the closing spring 36 is clamped between a plate-like, in the upper part 14 arranged filter holder 38 and the valve plate 34.
  • the valve holder 32 has two concentric with each other, annular through holes 40, 42, which are sealed in the closed position of the closing valve 30 of the valve plate 34.
  • the through holes 40 and 42 are formed in a retaining plate 44 of the valve holder 23, wherein the retaining plate 44 is divided by the through holes 40 and 42 in an outer ring 45 and an inner ring 46 concentrically surrounding a cylindrical central portion 47 and by means of the outside of the central part 47 in radial direction protruding holding ribs 49 are fixed to the middle part 47.
  • the central part 47 comprises a hollow cylindrical shell 51, which is covered on the upper side by an end wall 52 and receives an electro-magnet 54. This is surrounded by an annular space 55 within the middle part 47 and is connected via a connection cable, not shown in the drawing, to a control unit of the vacuum cleaner 10, likewise not shown in the drawing, in electrical connection.
  • the valve disk 34 has an annular passage opening 57, which is penetrated by a plurality of radially aligned support ribs 58, which connect an outer annular region 60 of the valve disk 34 with a circular central region 61 of the valve disk 34. From the central region 61 is in the direction of the central portion 47 of the valve holder 32 from a guide sleeve 63 from above, which dips into the annular space 55 of the valve holder 32 and an iron plate 64 receives, which is glued into the guide sleeve 63.

  • the sealing rings 66, 67 and 68 thus define annular sealing lines which delimit a surface acted upon by the pressure difference forming at the closing valve 30.
