Definitions

  • the invention relates to a dust container for a vacuum cleaner according to the preamble of claim 1.
  • Such a dust container is known from DE-AS 19 51 306.
  • the dust inlet opening is closed by elastic flaps made of rubber or plastic, which are pressed into the interior of the dust receptacle when the suction hose is inserted, thus releasing the dust inlet opening.
  • the flaps automatically close the dust inlet opening under the influence of their elasticity.
  • the suction hose must first be at least partially pulled out of the suction nozzle in order to enable the flaps to pivot back into their closed position.
  • the object of the present invention is to design a dust container of the type mentioned in such a way that when the dust container is removed, a reliable closure of the dust inlet opening is ensured, regardless of the degree of filling.
  • the inventive closure device which is arranged on the front of the dust receptacle and can be pivoted laterally against a restoring force, ensures both reliable opening and reliable closing of the dust inlet opening. Since the closure device in its open position does not come into contact with the dirt accumulated in the dust container, on the one hand the safe function of the closure device is guaranteed regardless of the degree of filling of the dust container, on the other hand damage to the closure flap and thus inadequate closing of the latter is avoided. In addition, no additional handle, such as the insertion or removal of a suction hose into or out of the suction nozzle is required to open or close the dust inlet opening, since both opening and closing of the dust inlet opening takes place automatically only when the dust container is inserted or removed into or out of the vacuum cleaner.
  • a simple pivoting of the closure flap and thus an easier insertion of the dust receptacle into the vacuum cleaner is advantageously achieved in that the axis of rotation above the dust inlet opening on it vertical center line and the closure flap is provided radially below the dust inlet opening with a run-on slope, the tip of which is to the side of the vertical center line.
  • Dust receptacles with a lower overall height, in which there is little space above the dust inlet opening for pivoting the closure flap can have a closure flap which consists of two flap parts which together can be pivoted in opposite directions about an axis of rotation which lies above the dust inlet opening on its vertical center line, wherein each flap part is provided with a run-on slope, which are located laterally to the vertical center line of the dust inlet opening. It is particularly advantageous if the closure flap is divided along the vertical center line of the dust inlet opening.
  • a simple pivoting of the closure flap and thus an easier insertion of the dust container into the vacuum cleaner is also achieved according to an advantageous embodiment of the invention in that the axis of rotation lies radially below the horizontal center line of the dust inlet opening and a pivot arm is connected to the closure flap, which is connected when the Dust receptacle in the dust chamber of the vacuum cleaner hits a stop fixed to the housing.
  • the free end of the swivel arm can be designed as a support bracket on which the dust receptacle removed from the vacuum cleaner can be securely gripped. Due to the advantageous arrangement of the swivel arm and the possibly present support bracket, this closure flap is also suitable for dust receptacles with a lower overall height.
  • the restoring force which is always present in the vertically pivotable closure flap due to gravity is increased by the fact that at least one spring which resets the closure flap or the flap parts is provided.
  • the restoring force can also be increased in that both flap parts are provided with oppositely polarized permanent magnets on the surfaces of the flap parts facing in the closed position.
  • the arrangement of at least one resetting spring or oppositely polarized permanent magnets also enables the horizontally arranged dust inlet openings in hand and boiler vacuum cleaners to be closed automatically.
  • a cost-effective and easy-to-assemble coil spring or a leg spring that essentially only occupies the height of the closure flap can be provided as the resetting spring.
  • the arrangement of permanent magnets on the surfaces of the flap parts touching in the closed position advantageously provides a restoring force that is independent of any material fatigue and thus a reliable automatic closing of the dust inlet opening over the entire period of use.
  • 1 denotes a dust receptacle for a vacuum cleaner, the front 10 of which is provided with a dust inlet opening 2.
  • the dust inlet opening 2 is closed by a closure flap 4 which is arranged such that it can pivot about a rotational axis 5 lying radially above the dust inlet opening 2 on its vertical center line 2a.
  • a seal 3 is arranged in the area of the dust inlet opening 2, on which the closure flap 4 lies completely in its closed position with its part lying below the pivot point 5.
  • the leg spring 15 is fitted with its spring turn on a pin 16 lying laterally to the axis of rotation 5.
  • One leg 15a of the leg spring 15 is fixed by means of two pins 17 and 18 on the front 10 of the dust receptacle 1, while the other leg 15b of the leg spring 15 bears against the outer edge of the closure flap 4.
  • the closure flap according to FIG. 2 consists of two flap parts 8 and 9 which are divided along the vertical center line 2a of the dust inlet opening 2 and which together can be pivoted in opposite directions about the axis of rotation 5 lying on the vertical center line 2a. Both flap parts 8 and 9 are provided below the dust inlet opening 2 each with a run-up slope 11 or 12, each run-up slope 11 or 12 lying on one side of the vertical center line 2a and at an angle of approximately 45 ° to the vertical center line 2a runs. The flap parts 8 and 9 are each held in their closed position by a leg spring 15.
  • the leg springs 15 are plugged with their spring turn onto pins 16 lying laterally to the axis of rotation 5 and are fixed with their one leg 15a in each case between a pin 17 protruding on the front side 10 and the protruding upper edge 26 of the dust receptacle 1.
  • the other leg 15b of the leg springs 15 lies against the respective outer edge of the flap parts 8 and 9.
  • a helical spring 19 can also be provided, which is fixed above the dust inlet opening 2 with one end in each case on one of the flap parts 8 or 9.
  • Both the leg springs 15 and the helical spring 19 exert a restoring force on the two flap parts 8 and 9, which forces both flap parts 8 and 9 into their closed position when the dust holding container 1 is removed.
  • the closure flap shown in FIG. 3 matches the mechanical dimensions of its flap parts 8 and 9 with the flap parts 8 and 9 described in FIG. Instead of the springs returning the flap parts 8 and 9, however, oppositely polarized permanent magnets 20 and 21 are provided, which are inserted into the surfaces of the flap parts 8 and 9 facing each other in the closed position. The restoring force described in FIG. 2 is also achieved by these permanent magnets 20 and 21.
  • FIG. 4 shows a partial section of the vacuum cleaner, the insertion of the dust container 1 in the open dust chamber 14. From the closure flap according to FIG. 2, only the flap part 8 with its run-on slope 11 is visible. The dust receptacle 1 is already partially inserted into the dust chamber 14, so that the flap parts 8 and 9 with their run-up bevels 11 and 12 respectively rest on the suction nozzle end 13a.
  • FIGS. 6 and 7 essentially corresponds to the dust receptacle 1 described above.
  • a further embodiment of a closure flap 40 is shown in FIGS. 6 and 7.
  • This closure flap 40 can be pivoted about an axis of rotation 5 lying radially below the horizontal center line 2b of the dust inlet opening 2 and laterally with respect to the vertical center line 2a of the dust inlet opening 2.
  • a swivel arm 7 is arranged radially below the dust inlet opening 2 at an angle of approximately 90 °.
  • a support bracket 7a can additionally be integrally formed on this swivel arm 7.
  • the closure flap 40 In its closed position, the closure flap 40 lies partially on the seal 3 and thereby reliably closes the dust inlet opening 2.
  • the swivel arm 7 of the closure flap 4 with its rolling bevel 27 in the area of the vertical center line 2a of the dust inlet opening 2 hits the bottom of the dust chamber 14 serving as a stop fixed to the housing Arrow 23 thus exerts a pivoting force on the closure flap 40.
  • the closure flap 40 is thereby pivoted against the restoring force of a leg spring 15 from its closed position into the open position shown by a dash-dotted line, so that the dust inlet opening 2 can be coupled in alignment to the suction nozzle end 13a located in the dust chamber 14.
  • the leg spring 15 is concentric with its spring turn to the axis of rotation 5 of the closure flap 40 arranges.
  • One leg 15a of the leg spring 15 is fixed on the front 10 of the dust container 1 in a slot 28, the other leg 15b of the leg spring 15, however, on the closure flap 40.
