Definitions
- the present invention relates to a vacuum cleaner with a secondary air valve having a movable closure element, an elastic element and a separator with a secondary air opening, wherein the closure element can be brought by the elastic element in a closed position to close the secondary air opening and the closure element against a closing force of the elastic element can be brought into a deviating from the closed position open position to release the secondary air opening.
- European Patent Application EP 1 514 505 A2 discloses an apparatus for preventing overloading of an engine during operation of a vacuum cleaner having an air damper and an elastic member.
- a tapered portion of the louver is formed so that a corresponding tapered opening in a portion separating a motor housing from a dust collection housing can be closed.
- German Patent DE 10 2006 030 227 B3 discloses a secondary air valve for a vacuum cleaner which has a housing in which two secondary air openings are formed on the lateral upper part. At the upper part of the housing is a valve hole.
- the valve also comprises a closure element and a spring element, which presses the closure element against the valve opening bore, so that the valve opening bore and the secondary air openings are closable.
- the pressure force of the spring element is higher than the negative pressure that results from the predetermined during normal operation of the vacuum cleaner suction.
- the negative pressure acting on the closure element is higher than the pressure force of the spring element, so that an additional air path through the valve opening bore and the secondary air openings is opened.
- the invention has for its object to provide a comparison with the prior art improved vacuum cleaner.
- a vacuum cleaner with a secondary air valve should be provided, in which the opening and closing behavior of the secondary air valve can be improved.
- a secondary air duct By means of a secondary air valve, a secondary air duct, also called a bypass duct, can be opened in order to supply additional air from the environment to a vacuum chamber of a vacuum cleaner. If the negative pressure applied to the secondary air valve increases, the closure element can be brought into an open position from a defined value of the negative pressure against the closing force of the elastic element, in which the secondary air duct is open. This can be prevented in an interruption of the suction air flow, eg in a clogged suction line, that the vacuum cleaner motor is damaged by overheating.
- the force acting on the closure element is related to the negative pressure and can result, for example, by the size of the negative pressure and the opening area of the secondary air opening.
- the separator of the secondary air valve separates the vacuum chamber from the environment.
- the vacuum chamber can also be separated from the environment by further elements of the vacuum cleaner, for example by the vacuum cleaner housing.
- the vacuum cleaner housing usually There is a bleed valve between the cable drum chamber and the dust chamber, so that the secondary air can flow from the connected to the environment cable drum space in the vacuum chamber with dust.
- the force-path diagram of the secondary air valve describes the relationship between the degree of opening of the closure element in an open position with respect to the closed position and a force that must be expended to hold the closure element in the corresponding open position.
- the opening degree may e.g. be given as a distance or as an angle.
- a force-angle diagram is a force-displacement diagram.
- a force-displacement diagram is determined by a force-displacement measurement. In such a measurement, e.g. a mechanical scanning method is performed in which the closure element is opened by a button by the button engages the closure element and this applied to an increasing force. Meanwhile, a force-displacement meter can measure the applied force and the distance traveled.
- the second derivative of the force as a function of the path is less than zero. This means that the slope decreases in the degressive range of the characteristic curve.
- a secondary air valve can be easily opened when a predetermined negative pressure in a vacuum chamber of the vacuum cleaner.
- the degressive characteristic curve can advantageously enable a smaller force to be required for the same proportion of travel with increasing degree of opening of the closure element.
- the closure element can be opened at lower forces compared to a linear or even progressive characteristic, which can lead to a faster opening and closing of the secondary air valve.
- the flutter behavior is reduced by reducing the force necessary to keep the secondary air valve open.
- the secondary air valve already opens at lower forces, so that the force which is applied to the closure element when the secondary air valve is open can be greater than the force required to keep the closure element open. Because of this, fluctuations in the force may be less pronounced on the position of the closure element and flutter of the bleed valve can be reduced. This may allow a more comfortable for the user vacuum cleaner operation, since he may feel a flutter of the bleed valve as annoying. In addition, unnecessary customer complaints can be avoided because a user often suspects a defect in the vacuum cleaner when the secondary air valve flutters.
- the characteristic curve extends degressively via an opening path of the closure element from the closed position to an open end position.
- the open end position of the closure element is an open position in which the closure element opens the secondary air opening maximum.
- the open end position is the position of the open positions of the closure element in which the maximum amount of air can flow through the secondary air opening.
- Most of the open end position is determined by a stop which limits the movement of the closure element during opening. Due to the degressive curve of the characteristic curve over the opening path, that is, through the degressive course of the entire characteristic curve, the flutter behavior of the secondary air valve can be reduced even further.
- the degressive region of the characteristic curve has a vertex.
- the degressive range of the characteristic curve is the section of the characteristic curve in which it is degressive.
- the vertex can also be called a local maximum.
- the characteristic decreases in its degressive range from the vertex with increasing and decreasing path. This means that the force for holding the closure element in the corresponding position becomes smaller with increasing and decreasing path. In this way it can be achieved that the secondary air valve opens abruptly when exceeding an opening threshold value defined by the vertex. Because due to the sloping characteristic, the force required to hold the valve open is less than the opening threshold.
- the value of this force results from a local minimum of the characteristic curve, which adjoins the vertex as the path increases.
- the holding value can be the value of the force which results when the closing element is open at maximum, ie at the maximum value of the path.
- the characteristic curve can not run infinitely with increasing path due to the design of the secondary air valve, but end at a maximum value of the path. At this end point of the characteristic, the closure element can be in the open end position.
- the holding value can therefore be determined by a stop. Because the holding value is lower than the opening threshold value, a hysteresis behavior of the secondary air valve can be made possible during opening and closing.
- a novel bleed valve without flutter characteristics that after a first-time opening of the bleed valve due to an undesirable increase in the negative pressure in the vacuum chamber, a sufficiently large amount of air can flow through the bleed valve until normal pressure conditions prevail in the vacuum chamber again.
- Such regular pressure conditions prevail, for example during normal operation of the vacuum cleaner.
- An increase in the negative pressure can be caused for example by a stuck eyes on objects or a clogged suction line.
- the force indicated in the force-displacement diagram is perpendicular to the opening area of the secondary air opening.
- the direction of the force is preferably directed in the flow direction of the secondary air flow, wherein the flow direction of the secondary air flow is perpendicular to the opening surface of the secondary air opening and is determined by the formation of the secondary air valve without closure element.
- the opening area of the secondary air opening is through an opening edge of the secondary air opening spanned.
- the vertical force can also be a force component of a force acting on the closure element.
- the opening degree can be specified as an angle or as a distance.
- the force indicated in the force-displacement diagram is perpendicular to the closing surface of the closure element, wherein the closing surface is a surface of the closure element, which covers the opening surface of the secondary air opening in the closed state of the closure element and thereby closes.
- the path indicated in the force-displacement diagram is the distance of a point of the closure element from an opening surface of the secondary air opening.
- the path indicated is the distance of the centroid or the center of gravity of the closing surface of the closure element to the opening surface of the secondary air opening.
- the distance of a point of the shutter member is the length of a distance leading from the point to the opening area and perpendicular to the opening area.
- the characteristic is degressive at least in sections in a force-displacement diagram in which the distance of a point, e.g.
- the characteristic is degressive at least in sections in a force-displacement diagram in which the distance of a point, e.g. the center of gravity of the closing surface of the closure element, is given to the opening surface as a path and a force perpendicular to the closing surface of the closure element force.

- the nature of Movement of the closure element during opening and / or closing of the secondary air valve that is, by the kinematics of the closure element with respect to the separating element, results in the at least partially degressive characteristic of the secondary air valve.
- This may allow a bleed valve according to the invention with a degressive behavior, although an elastic element with a linear or even progressive spring characteristic is arranged in the bleed valve.
- the spring characteristic of the elastic element is given as a force-displacement diagram and describes the dependence of a force which must be applied in order to move two points of the elastic element, preferably the two ends, relative to one another. Namely, as the degree of opening of the shutter member which is opened by a force, the proportion of the spring force acting in the direction of the applied force due to the kinematics increase less with increasing degree of opening of the shutter member for the same proportion of way, whereby the degressive characteristic arises. Depending on the design of the secondary air valve, a degressive characteristic curve or even a degressive characteristic curve with vertex can be achieved.
- the characteristic curve can be even more degressive or even have a vertex.
- the characteristic curve then runs degressively if the slope in the declining-balance region of the characteristic curve decreases more sharply, ie the characteristic becomes flatter with increasing distance.
- the closure element is connected via a hinge with the separating element.
- the closure member may be pivoted about an axis of rotation of the hinge to be opened and closed.
- the characteristic curve of the secondary air valve is degressive even if the degree of opening of the closure element is indicated as the opening angle in a force-angle diagram.

- FIG. 10 is a sectional view of the third embodiment of the secondary air valve with the closure element in an open end position.
- Fig. 1 is a sectional view of a vacuum cleaner 10 with a secondary air valve 30.
- the vacuum cleaner 10 is equipped with a vacuum cleaner motor 1 1, which drives a fan 13, through which a suction air flow 15 is generated.
- a negative pressure is generated in a vacuum chamber 21, which is a dust chamber.
- the vacuum chamber 21 is the vacuum cleaner motor 1 1 and the fan 13 in the direction of the suction air flow 15th upstream.
- a motor protection filter 17 is arranged.
- the bleed valve 30 is attached to a vacuum space wall 23 of the vacuum space 21 that separates the vacuum space 21 from an ambient space 25 that is a cable drum space.
- the secondary air valve 30 can open a secondary air passage and thereby throttling or interrupting the Saugluftstroms 15 via the flowing through the secondary air valve 30 Compensate for air.
- This secondary air channel is established between the vacuum chamber 21 and the surrounding space 25.
- the ambient space 25 is connected to the environment surrounding the vacuum cleaner 10 so that the atmospheric pressure prevailing in the environment is thus also present in the surrounding space 25.
- the secondary air valve 30 is shown in FIGS. 2 to 4.
- Fig. 2 is a view of the secondary air valve 30 from above.
- Fig. 3 is a sectional view of the secondary air valve 30 along the line AA of Fig. 2, wherein a closure element 50 is in the closed position.
- a sectional view of the secondary air valve 30 along the line AA of FIG. 2 with the closure element 50 in an open end position is shown in FIG. 4.
- the movable closure element 50 of the secondary air valve 30 is pivotally connected via a hinge 41 with a separating element 33 of the secondary air valve 30.
- the separating element 33 is arranged with the auxiliary air chamber 30 mounted between the vacuum chamber 21 and the surrounding space 25, so that it, like the vacuum chamber wall 23, separates the vacuum chamber 21 from the surrounding space 25.
- the separating element 33 has a secondary air opening 60, through which air can flow from the surrounding space 25 into the vacuum chamber 21.
- the secondary air valve 30 further has an elastic element 37, which acts on engagement points 39 on the closure element 50 and the separating element 33 in order to exert a force on the closure element 50.
- the closure element 50 can therefore be brought into a closed position by the elastic element 37 in order to close the secondary air opening 60.
- the Closing element 50 is pressed against the separating element 33, whereby a closing surface 51 of the closure element 50 covers the auxiliary air opening 60 and thus closes.
- the closed secondary air valve 30 is a static negative pressure, namely the pressure prevailing in the vacuum chamber 21 negative pressure. If this negative pressure exceeds a response pressure of the closed secondary air valve 30, the closing force of the elastic element 37 can be overcome and the closure element 50 can be brought into an open position against the spring force of the spring element 37, also referred to as closing force. This corresponds to the opening of the secondary air valve 30, in which the secondary air duct between the vacuum chamber 21 and the surrounding space 25 is opened.
- the closure element 50 can thus be brought against a closing force of the elastic element 37 in a deviating from the closed position open position to release the secondary air opening 60.
- the secondary air valve 30 By opening the secondary air valve 30 is added to the static pressure still a dynamic pressure in the form of the secondary air flow.
- the static pressure decreases and the dynamic pressure increases.
- the closure element 50 is opened until the sums of the two pressures, ie the static and dynamic pressure, is greater than the restoring force exerted by the elastic element 37 on the closure element 50. In the open end position, the closure element 50 is held by the secondary air flow.
- the open end position of the closure element 50 is an open position in which the closure element 50 opens the auxiliary air opening 60 to a maximum. This open end position is determined by the fact that the closure element 50 can not be opened on reaching a stop. This stop is realized by a projection 57 of the closure element 50 formed in the region of the joint 41.
- a fixing region 71 of the closure element 50 and the separating element 33 locking elements 70 are arranged, in which engages the elastic element 37.
- the elastic element 37 has in the closed position of the closure element 50 to a bias and is clamped due to this bias between two locking elements 70.
- the elastic element 37 can engage in various locking elements 70, so that the distance between the points of attack 39 and thereby acting on the closure element 50 spring force can be varied.
- the elastic element 37 is thus adjustable via latching elements 70 of the closure element 50 and the separating element 33 in its spring strength.
- the elastic element 37 designed as a leaf spring has an omega-shaped course between the points of application 39, so that the course of the elastic element 37 from the closure element 50 to the separating element 33 has at least three alternating curvatures.
- Fig. 5 is a force-displacement diagram of the secondary air valve 30 is shown, in which the opening degree of the closure element 50 is indicated in a position as the path X.
- This distance X is the distance of the center of the surface 53 of the closing surface 51 of the closure element 50 to an opening surface 61 of the secondary air opening 60, which is spanned by the opening edge 63 of the secondary air opening 60. This distance is zero when the closure element 30 is in the closed position.
- the force F indicated in the force-displacement diagram must be used to hold the closure element 30 in a position determined by the path X. This force F is perpendicular to the opening area 61 of the secondary air opening 60 and is applied during the opening of the closure element 50 by the negative pressure and by the secondary air flow.
- the direction of the force F is directed in the flow direction 31 of the secondary air flow, wherein the flow direction 31 of the secondary air flow is perpendicular to the opening surface 61 of the secondary air opening 60 and is defined by the formation of the secondary air valve 30 without closure element 30.
- the force F depends on the negative pressure and the size of the opening area 61 of the secondary air opening 60.
- the two characteristic curves K1 and K2 shown in FIG. 5 show examples in which the elastic element 37 engages on different latching elements 70.
- the two curves shown in Fig. 4 K1 and K2 extend over the opening path of the closure member 30 from the closed position shown in Fig. 3 to the open end position shown in Fig.
- the secondary air valve 30 opens abruptly when an opening threshold 83 of approximately 1.6 N is exceeded.
- the holding value 85 that is, the force necessary to keep open the secondary air valve 30, which in the example of the characteristic K1 is approximately 1.3 N
- the opening threshold value 83 means that the secondary air valve 30 shows a hysteresis behavior, since the secondary air valve 30 opens when the opening threshold 83 is exceeded and closes again when the holding value 85, which is less than the opening threshold 83, is exceeded. The result of this is that slight fluctuations in the force acting on the closure element 50 do not lead to any movement of the closure element 50, thereby preventing the secondary air valve 30 from fluttering.
- the separating element 33 has the shape of a cuboid, wherein the secondary air opening 60 is arranged on a top surface of the cuboid. The other top surface of the cuboid is open to allow the secondary air flow when the secondary air valve 30 is open.
- the locking elements 70 of the separating element 33 are arranged on the side surface of the cylinder, which adjoins the side 41 of the auxiliary air opening 60 opposite the joint 41.

- FIG. 8 shows a sectional view of the secondary air valve 30 along the line B-B from FIG. 6 with the closure element 50 in an open end position.
- the locking elements 70 of the separating element 33 are mounted on a side surface of the cuboid, so that due to the relative movement of the elastic element 37 and separating element 33 to each other, the degressive characteristic is formed.
- the closure element 50 is opened with increasing degree of opening of the closure element 50, ie, with increasing distance 55 of the center of area 53 of the closing surface 51 to the opening surface 61, the proportion of the path by which the points of attack 39 move toward one another is the same Share of a change in the distance of the center of area 53 to the opening area 61 less.
- the elastic element 37 is designed as a segment of a spherical shell, which is also referred to as a cambered circular blank.
- the elastic member 37 and the closure member 50 are made in one piece, wherein in the closed position of the closure member 50 and the elastic member 37, the auxiliary air opening 60 is closed by a part of the cambered blank. This closed position is in Fig. 7 shown. If the negative pressure in the vacuum space 21 exceeds a threshold value, the elastic element 37 and the closure element 50 are deformed until the open end position shown in FIG. 8 is reached.
- outlet openings 35 are arranged so that the secondary air from the surrounding space 25 through the auxiliary air opening 60 and the outlet openings 35 can flow into the vacuum chamber 21.
- the characteristic of the secondary air valve 30 in the force-displacement curve is degressive, since the cambered Ronde has a degressive spring characteristic as an elastic element 37.
- the distance 55 of the center of area 53 of the closing surface 51 is indicated to the opening area 61 of the sub-air valve 30 and the force perpendicular to the opening area 61 of the sub-air opening 60.
- the open end position shown in Fig. 8 is a metastable state, which arises when force is applied to the cambered Ronde in the closed position, which is a stable state, the Ronde is bent until it suddenly jumps through bumps in the open final state.
- the present invention makes it possible with simple structural and cost-effective means to provide a vacuum cleaner with a secondary air valve, which can be opened and closed again due to its at least partially degressively running characteristic.
- a secondary air valve can be provided in which the flutter behavior can be reduced.
