Description

  The present invention relates to a vacuum cleaner, in particular an electric motor driven vacuum cleaner, in some cases a vacuum cleaner dust collection filter bag which may be in the form of a self-propelled floor cleaning device, the dust filter bag being a holding plate The dust collection bag is fixed to the holding plate, and the holding plate has the supply opening, preferably closeable, for dust-containing air flowing in the supply direction substantially perpendicular to the opening surface of the supply opening In this case, the dust collecting filter bag for the vacuum cleaner is further provided with a lower holding section of the holding plate in front of the fixing surface to the holding plate of the dust collecting bag in the direction of supplying the dust-containing air. It is about.

  The invention further relates to a holding plate and a dust bag fixed to the holding plate in a vacuum cleaner, in particular a motor driven vacuum cleaner, possibly in the form of a self-propelled floor cleaning device. A dust collecting filter bag device, wherein the holding plate has a feed opening, preferably closeable, for dust-containing air flowing in the feed direction substantially perpendicular to the opening face of the feed opening. In this case, the vacuum cleaner further comprises a filter chamber for receiving the dust filter bag and a suction / blowing sleeve to which the attached dust filter bag is connected, in this case Further, the filter chamber is provided with a closing cover having a fitting projection that can be swung to remove or install the dust collecting filter bag. In this case, the closing cover is fitted with the fitting projection. Collection It is possible only when the filter bag and cooperates relates particulate filter bag apparatus for a vacuum cleaner machine.

  The present invention relates to various aspects. In particular, the installation of a new unused dust collecting filter bag in the filter chamber of the vacuum cleaner, and more preferably the removal of the used dust collecting filter bag from the filter bag chamber is also comfortable for the user. Must be executable. Furthermore, the operation of the vacuum cleaner must be ensured that the dust filter bag is installed.

  For this purpose, first, with respect to the dust filter bag, the lower grip section overlaps with the part of the holding plate that forms or transitions to the fixed surface in the projection direction corresponding to the supply direction, It is designed such that an engagement space is formed between the side gripping section and the retaining plate portion.

  The engagement space formed in the holding plate provides a convenient area for the user to grasp the filter dust bag when the dust filter bag is mounted in or removed from the filter chamber. The engagement space is formed in the region of the sanitary preferable holding plate. Correspondingly, therefore, gripping the holding plate, for example to carry a filled dust filter bag, can be carried out in a region away from the supply direction.

  Furthermore, the engagement space is formed to open radially outward with respect to an axis preferably through the center of the supply opening, in which case in the cross section in which the fixing surface is shown as a line, the engagement space is It is formed by a U-shaped region that opens outward in the radial direction of the holding plate.

  Here, the U-leg attached to the inflow side is formed by a lower gripping section, while the opposite U-leg forms a fixed surface or transitions to the fixed surface and is fixed on the radially outer side with respect to the axis of the supply opening It is formed by the part of the holding | maintenance board connected to. These U legs preferably extend parallel to each other. An acute angle of 1-30 °, preferably 1-10 °, may be formed between these U-legs, and in this case, the engagement space should only be from radially inward to radially outward. Instead, it may expand from the radially outer side toward the radially inner side.

  The opening surface of the supply opening is preferably formed in a sealing area that cooperates with a lid or the like in the closed position of the supply opening. Therefore, the supply opening is preferably provided in a sealing surface formed in the cooperating area between the lid and the holding plate.

  The supply direction may be considered the same as a straight line extending through the center of the inflow opening and extending into the dust bag following the center line of the suction / blowing sleeve on the vacuum cleaner side. In this regard, the closure lid is not considered. The actual feed direction, which also takes into account the effect of the flow due to the closure lid, approximates this, but does not run in a straight line.

  The straight line indicating the supply direction forms an acute angle with respect to the cross section of the supply opening, in which the sealing surface is shown as a line, approximately perpendicular to the sealing surface, preferably between 30-90 °, in particular 60-90 °. And stretch.

  Furthermore, the engagement space of the holding plate is open in the direction of the inset of the inset, with the inset being U-shaped in cross-section in the closed position of the closing cover with respect to the dust collecting filter bag device in the vacuum cleaner. It is used so that it can enter the engagement space.

  The correct positioning of the dust collecting filter bag in the filter chamber is ensured in cooperation with the engagement space via the fitting protrusion. Furthermore, this cooperation ensures that the dust collection filter bag is mounted in the filter chamber. When the dust collecting filter bag is not present, and therefore without cooperation with the engagement space of the holding plate, preferably the inset projections are locked against the area of the filter chamber, so that in a preferred form, In this situation, the filter chamber cannot be closed.

  The additional holding that is necessary in the case of the dust collecting filter bag in the filter chamber can also be achieved via a fitting projection inserted into the engagement space. Furthermore, in a preferred form, the snap-in projection acts so that the holding plate is airtight in the area of the supply opening and is crimped to the suction / blowing sleeve on the vacuum cleaner side.

  With respect to the central axis of the supply opening, which is shown as the center point in the plan view of the supply opening, the lower gripping section is at least radiused outside the fixing area to the holding plate of the dust bag in the projection direction along the supply direction At least most of the directions overlap. Since the dust bag is spaced from the lower gripping section, the engagement space is unaffected by the dust bag regardless of the degree of filling of the dust bag.

  Thereby, the engagement space can be used to hold the dust collection filter bag in a sanitary manner, particularly when the dust collection filter bag is removed from the filter chamber.

  In order to support the dust bag in the upside down arrangement of the dust bag in the filter chamber, in particular, the dust bag extends above the holding plate. It is preferable that a part of the holding plate extends outside the portion fixed to the holding plate in the radial direction.

  In a preferred form, the spacing between the lower gripping section and the part of the holding plate that transitions to the fixing surface or the fixing surface varies in the radial direction and / or in the circumferential direction, which is in particular the lower gripping section. And the portion of the holding plate that moves into the fixed plane diverges from each other. Accordingly, the mutually facing surfaces of the lower grip section and the portion of the holding plate that is spaced apart form an acute angle of 30 ° or less, more preferably 5-10 °.

  The retaining surface of the retaining plate generally extends in a plane that forms an acute angle of no more than 30 °, preferably 5-15 °, with the surface in which the lower gripping section extends in a cross-section where the surface is indicated by a line.

  The lower grip section is preferably formed only within a part of the periphery. Accordingly, the lower grip section preferably extends within the range of 1/10 to 1/5 around the retaining plate in the region of the face that receives the lower grip section.

  Two opposite gripping sections are preferably formed with respect to the central axis of the supply opening, and correspondingly two engagement spaces are formed. The engagement space can be engaged with each fitting protrusion of the vacuum cleaner.

  It is preferable that the fitting protrusion is swingable around the swinging shaft, and in this case, the fitting protrusion is swung around the swinging shaft at the inserted position. In a position that is not affected by the holding plate or the engagement space, the fitting protrusion is preferably moved to a basic position that is spring-biased and constrained, and is fitted when there is no holding plate or when there is no dust collecting filter bag. In this basic position, the projection is restrained by striking against a section of the filter chamber or vacuum cleaner. Only when the retaining plate fitted with the fitting projection is inserted into the attached engagement space, the fitting projection swings to a position that allows the filter chamber to be closed.

  The snap-in projection enters the engagement space in an entry direction perpendicular to the extension direction of the lower grip section. In the substantially U-shaped cross-sectional shape of the engagement space, it is preferable that the fitting protrusion enters the engagement space at a right angle to the U-section.

  While the inset projection cooperates with the retaining plate in closing the closure cover, the inset projection provides a predetermined positioning of the retaining plate seal relative to the suction / blowing sleeve or the bottom of the filter chamber. Also preferably, in the subsequent closed position of the closing cover, the snap-in projection is pressed and held in this position so that the sealing area of the retaining plate, for example in the form of a ring collar with sealing lips, forms a sealing fit. Apply force to the retaining plate.

  A closure prevention device is preferably provided in the filter chamber. The closure prevention device cooperates with an associated snap-in projection when trying to move the closure cover to the closed position when the dust filter bag is not installed or is not installed correctly. In this case, the fitting protrusion does not enter the engagement space even if it is swung, and strikes a closing prevention device that prevents further swinging of the closing cover.

  The closure prevention device may be a rib or a protrusion. It is preferred that a closure blocking pocket is provided in which the inset projection enters a partial area.

  Two inset projections are preferably provided. Preferably, each of the two snap-in projections is accompanied by a closure prevention device.

  It is preferable that the fitting protrusions are held on the closing cover so as to be able to swing independently of each other. The swinging movement of one of the fitting protrusions is based on a unique motion and does not necessarily follow the movement of the other fitting protrusion.

  Therefore, it is preferable that the holding plate can be transferred to the airtight fit and / or can be held in the airtight fit by the one or more fitting protrusions.

  First, referring to FIG. 1, a vacuum cleaner 1 of the type of a manual electric vacuum cleaner operated with a handle, comprising a basic housing 2 including a motor / fan unit not shown, The vacuum cleaner 1 is shown and described, connected to an openable filter chamber 3 for the dust collecting filter bag 4.

  In order to operate the vacuum cleaner 1, a handle 5 is fixed to the basic housing 2. The handle 5 has a hand grip 6 at the end, and the hand grip 6 is provided with a switch 7 for starting and operating the vacuum cleaner 1 electrically. Electricity is supplied through an electric cable 8, and the electric cable 8 enters the hand grip 6.

  In the illustrated embodiment, the floor is cleaned through the floor nozzle 9. The floor nozzle 9 is coupled to the basic housing 2 and the motor fan unit arranged therein via a joint 10 not shown in detail, both in flow technology and possibly electrically.

  During operation of the vacuum cleaner 1, the dust collection filter bag 4 is held in the filter chamber 3. The dust collection filter bag 4 has a dust collection bag 12 fixed to a holding plate 11. The dust bag 12 is preferably formed from wool.

  The filter chamber 3 can be opened in order to remove the dust collection filter bag 4 and in particular to allow the dust collection filter bag 4 to be replaced. For this purpose, a part of the filter chamber 3 is formed as a lid-like closing cover 13, and the closing cover 13 can swing around the swing axis x with respect to the fixed part of the filter chamber 3.

    In FIG. 2, the closing cover 13 is shown in a closed blocking position with respect to the closing movement of the cover.

  A suction through-opening 14 is formed in the filter chamber 3, and dust sucked in the operating state is collected through the suction through-opening 14 in the dust collection filter bag 4 existing in the filter chamber 3. Depending on the form of the vacuum cleaner 1, dust can be blown into or sucked into the dust collecting filter bag 4.

  When the vacuum cleaner 1 is in use, the filter chamber 3 is substantially perpendicular or vertical with respect to its longitudinal direction, corresponding to the direction of the bottom surface 16 which is visible here and to other surfaces which are not shown in the drawing. It is preferable that they may be arranged extending at an acute angle with respect to the line.

  A fitting projection 15 is arranged inside the closing cover 13. It is preferable that two fitting protrusions 15 that are spaced apart from each other in the extending direction of the swing axis x are provided.

  As can be seen from FIG. 2, each fitting protrusion 15 can be arranged inside the closing cover 13. In this case, it is more preferable that each fitting protrusion 15 is disposed on the closing cover 13 so as to make a swinging motion. In this case, the swinging axis y of each fitting protrusion 15 is set to the swinging axis x of the closing cover 13. It is preferred to extend parallel or at least approximately parallel.

  The fitting protrusions 15 are arranged so as to be able to swing around the respective swinging shafts independently of each other. The swing of one fitting protrusion 15 does not necessarily follow the swing of the other fitting protrusion 15.

  This can be achieved by individual formation of the inset projections 15. Both the fitting protrusions 15 may be formed in advance so as to be easy to mount, for example, by forming a bond between the fitting protrusions, so that this connection allows independent rocking of the fitting protrusions 15. Good.

  Each fitting protrusion 15 may be further spring-biased to the fitting position. For this purpose, it is further preferred that a spring, for example a leg spring, is attached to each inset projection 15, which urges the inset projection 15 into a pivot position, preferably limited by a stopper. In the moving position, even if an attempt is made to close the closing cover 13, the snap-in projection 15 enters and locks into a closing prevention device formed in the bottom surface 16 of the filter chamber 3 without using any other means. .

  The closure prevention device may be a shoulder or projection that allows cooperation with the attached telescoping protrusion 15. The closure blocking device is preferably a closure blocking pocket 17 which extends open below and into the bottom surface 16 (see also FIG. 18).

  Each inset projection 15 is associated with a closure prevention device, in particular a closure prevention pocket 17.

  The fitting position shown in FIG. 2 corresponds to the fitting projection 15 cooperating with the closing prevention pocket 17 so that the closing of the closing cover 13 is prevented when the dust collecting filter bag 4 is not mounted. And act to be locked. Abnormal closure of the filter chamber 3 can prevent the vacuum cleaner 1 from starting using electrical and / or mechanical means.

  In order to allow the closure cover 13 to be moved to the closed position of the filter chamber 3, the inset projection 15 is turned against the spring force acting on it, so that entry into the closure prevention pocket 17 is prevented. In addition, the turning of the fitting protrusion 15 is assumed.

  This turning operation of the fitting protrusion 15 is given by the region of the holding plate 11 when the dust collecting filter bag 4 is mounted.

  In the figure, only the holding plate 11 of the dust collecting filter bag 4 is essentially shown. As can be seen from the drawing, only the outline of the dust bag 12 connected to the holding plate 11 is shown by a one-dot chain line, and is not completely shown.

  In the embodiment, the holding plate 11 is preferably formed in a lattice shape within the range of the fixed surface E with respect to the dust bag 12. The holding plate 11 may be formed as a plastic injection molded product.

  The holding plate 11 has a supply opening 18, and the supply opening 18 is surrounded by a collar 19 protruding into the dust bag 12. The supply opening 18 is closed by a lid-like closing part 20, in particular when the vacuum cleaner 1 is switched off, i.e. when no suction air flow is formed. The closing part 20 is swingable from the closed position of the supply opening to the open position, preferably about an axis extending parallel to or at least approximately parallel to the swing axis x of the closing cover 13, in this open position, The closing part 20 has been moved in the direction inside the bag (for this purpose see FIG. 7).

  The movement of the closed part 20 to the open position is preferably performed only by the suction air flow acting on the closed part 20 during operation of the vacuum cleaner 1. There may be provided opening assisting means for mechanically acting on the closing part 20 to assist the opening process.

  As indicated by the alternate long and short dash line 21 indicating the outer coupling contour of the dust bag 12 to the holding plate 11, the holding plate 11 is arranged in the lateral direction, here within the extension width of the filter chamber 3. Protrude beyond.

  The holding plate 11 is preferably formed in a lattice shape in the portion 23 of the holding plate 11 that protrudes beyond the dust bag 12, and preferably also in other portions, whereby the vacuum cleaner 1 The lower support of the dust bag 12 filled during the continuous operation can be achieved. In this case, this portion 23 of the holding plate 11 that forms the fixed surface E on the upper side is formed by a lattice structure, so that the vacuum cleaner Depending on the operation mode of the one, the through flow of the air sucked from the dust bag 12 or blown from the dust bag 12 is enabled.

  A lower grip section 24 is formed in the holding plate 11 attached to each portion 23 of the holding plate 11 configured in a lattice shape. Simultaneously with the part 23 configured in a grid, two lower gripping sections are preferably formed in the basic body of the holding plate 11 which provides a fixing surface 22 for the dust bag 12.

  In the projection in the direction of the supply direction of dust-containing air flowing into the dust bag 12 (see arrow a in FIG. 7), the lower grip section moves to the fixed surface 22 and each attached portion of the holding plate 11 23, at least partly overlaps, and in this case, an interval in the supply direction a is provided between the lower gripping section 24 and the part 23 of the attached holding plate.

  Each lower gripping section 24 extends within approximately 1/5 of the circumference of the holding plate 11, in particular the circumference of the basic body of the holding plate 11. Furthermore, each lower gripping section 24 essentially has a narrow side length as viewed perpendicular to the longitudinal extension direction of the holding plate 11 from the holding plate edge extending substantially parallel to the hinge axis of the closing portion 20. It extends within a range of about 1/3 to 1/2 (see dimension L in FIG. 10).

  In the cross section of the region of the retaining plate 11 that supports the lower gripping section 24, the lower gripping section 24, the portion 23 configured in a grid and the attached basic body section of the retaining plate 11 define a U-shaped engagement space 25. Form. The U-shaped engagement space 25 is open on both sides in the longitudinal extension direction of the lower gripping section 24, i.e. in the extension direction of the shorter holding plate dimension L, and also on the side away from the basic body of the holding plate. I.e. also radially outward with respect to the central axis z passing through the supply opening 18.

  The faces of the lower grip section 24 facing each other (face F) and the face of the retaining plate portion 23 (face E) form an acute angle α of about 5-10 ° in the longitudinal direction of the lower grip section 24; In this case, the spacing decreases uniformly in the direction of the section of the retaining plate portion 23 that extends beyond the lower gripping section 24.

  Correspondingly, the abutment surface of the lower gripping section 24 directed in the direction of the retaining plate portion 23 also extends at the aforementioned angle with respect to the fixing surface 22 for the dust bag 12.

  The engagement openings 25 arranged to face each other, for example, when the user puts two fingers into the engagement space 25 and supports the holding plate 11, the dust collection filter bag 4, particularly the dust collection filter bag 4 filled. It is advantageous that it can be used advantageously to remove or even carry it. In this case, the portion 23 of the holding plate configured in a filter shape does not come into contact with the wall of the dust bag that is spaced from the engagement space 25.

  Further, the lower engagement section 24 is positioned so that the lower engagement section 24 covers the chamber-side closing prevention pocket 17 in a state where the dust collection filter bag 4 is mounted in the filter chamber 3 ( (See FIG. 5).

  The holding plate 11 of the dust collecting filter bag 4 has a suction collar that protrudes into the filter chamber 3 on the lower side, that is, the seal collar 26 of the holding plate 11 that circulates on the opposite side of the collar 19. It is mounted in the filter chamber 3 so as to surround the connecting collar 27 of the blowing sleeve 32. The suction / blowing sleeves 32 are all formed on the end side of the suction channel 28 led into the basic housing 2.

  The sealing collar 26 of the retaining plate 11 is further provided with a sealing lip 29 that makes one round. The sealing lip 29 cooperates with the connecting collar 27 so as to be radially inward from the circumferential edge of the sealing collar 26. It is preferable to protrude in the direction.

  After the dust filter bag 4 is mounted by the user, it is preferable that the holding plate 11 is first positioned at the temporary mounting position (see FIG. 4).

  When the closing cover 13 is moved in the direction of the closed position of the filter chamber 3, the fitting projections 15 enter into the engagement space 25 on the holding plate side, each of the fitting projections 15 facing the holding plate portion 23. It is supported on 24 contact surfaces. As a result, the fitting protrusion 15 is turned against the spring force acting on the fitting protrusion 15.

  When the closing cover 13 is further swung into the closed position, the fitting protrusion 15 slides on this abutment surface of the lower gripping section 24 and further enters the respective engagement space 25.

  The swinging movement of the fitting protrusion 15 performed against the spring force is preferably limited by a stopper (abutting protrusion 35), so that the closing cover 13 is completely in the closed position as shown in FIG. When moved, a force component is applied to the lower grip section 24 via the fitting protrusion 15 to move the holding plate 11 (further) to the airtight fitting position shown in FIG. The horizontal basic shape of the seal lip 29 changes in cooperation with the outer surface of the connection collar 27, and the seal lip 29 is curved and abuts against the outer surface of the connection collar 27 so as to be airtight.

  The holding plate is supported on the bottom surface 16 at the same time.

  The airtightness between the connecting collar 27 and the bottom 16 of the filter chamber is, for example, a connection acting on the bottom of the filter chamber from below, which is injection molded as a 2K soft component or surrounds the connecting collar 27 as a separately mounted seal. This is achieved by the color 27 section.

  In order to mount the holding plate 11 in a correct position, a web-like positioning projection 30 is provided on the bottom surface 16, and the positioning projection 30 is a positioning slit 31 formed in the portion 23 of the holding plate configured in a lattice shape. Engage with.

  The holding plate 11 may be formed with a protrusion that cooperates with the recess and / or the notch in the receiving chamber.

  FIG. 15 shows the face of the retaining plate portion 23 with a rear gripping area 33 of the retaining plate having a width greater than the distance between the edges of the positioning protrusions 30 facing each other (this surface saves material, for example). Therefore, one form of the holding plate 11 is shown. A width corresponding to this interval or a width exceeding this interval is provided in the wider region of the holding plate portion 23.

  This enables (intuitively) correct placement of the holding plate 11 in the filter chamber 3. The holding plate 11 erroneously mounted in the reverse direction of 180 ° is not positionable because the holding plate 11 slides forward due to the bottom surface 16 disposed at an inclination. The holding plate 11 is supported by the positioning protrusion 30 at the correct mounting position by the rear grip region 33.

  Instead of the bottom-side closing prevention pocket 17, a closing prevention rib that protrudes upward from the bottom surface may be provided. When the dust collecting filter bag 4 is not attached, the fitting protrusion 15 strikes the closing prevention rib. Locked. When the dust collecting filter bag 4 is mounted, the closing prevention rib is received by a pocket or the like formed on the lower side of the lower grip section 24.

  For example, the dust bag 12 may be folded on the manufacturing side or may be folded compactly as a roll (see FIG. 16). The compact shape is held by one or more, in particular two band-like material bands 34 that surround at least part of the dust bag 12 and the holding plate 11. The material band 34 may be a paper band.

  The material band 34 tightens the engagement space 25 from above.

  In the middle of the closing process of the closing cover 13, first, the tip of the fitting protrusion 15 strikes the surface of the material band 34. When the fitting protrusion 15 further enters the engagement space 25, the material band 34 is fully extended and finally is broken as planned.

  By the closing movement of the cover, the fixing action of the one or more material bands 34 is released, so that the dust bag 12 is supported by the vacuum action on the dust bag wall when the vacuum cleaner 1 is in operation. The final size and shape of the crease / roll is extended.
