Description

[0001] The invention relates to a connector for a vacuum cleaner for detachable connection of a suction hose to a suction opening provided in a vacuum cleaner housing, wherein the connector with a tubular end piece can be inserted in the suction opening.

[0002] Such a vacuum cleaner is known from DE 42 40 913 A1. In the known vacuum cleaner there is provided a vacuum cleaner hose which is detachably coupled to a connector via a coupling element. The connector has a tubular end piece which can be inserted in a suction opening in a vacuum cleaner housing. The connector has a circular cross-section and is thus rotatably mounted in the vacuum cleaner housing.

[0003] It is the object of the invention to improve a connector of the type described initially.

[0004] This object is solved according to the invention by the fact that the connector can be guided through a first outer and a second inner wall of the vacuum cleaner housing.

[0005] The connector according to the invention provides a particularly stable and secure connection between the vacuum cleaner hose and the vacuum cleaner housing.

[0006] In an advantageous development of the invention, the connector with a connecting cone dips in a sealing fashion into a dust container. By means of this measure, the connector is on the one hand fixedly connected to the dust container, thus for example in the case of a dust bag, to its filter cardboard, but despite this the dust bag can be changed even when the connector is inserted since the connector does not dip into or does not dip deeply into the dust bag.

[0007] A further advantage of the invention is that the connector can be fixed in a region between the first and the second wall. As a result of this arrangement, a high stability is achieved.

[0008] In an advantageous further development, the connector has a sealing lip which sits on the outside of the second wall and by which means it can be fixed on the second wall.

[0009] The connector preferably has at least one catch lug by which means the connector can be fixed on the inside of the first wall. The stability of the connector is also increased by this measure.

[0010] In an advantageous development of the invention there is provided a gripping element accessible from the outside of the wall by which means the at least one catch lug can be pressed backwards and the connector can be withdrawn from the vacuum cleaner housing.

[0011] The gripping element is advantageously formed by a catch hook on which the catch lug is respectively arranged.

[0012] The arrangement of a gripping recess on the catch hook is especially advantageous. The connector can thereby be conveniently and rapidly separated from the vacuum cleaner housing.

[0013] The invention is explained in further detail below in an exemplary embodiment with reference to the drawings. In the figures:

[0014] FIG. 1 is a longitudinal section through a connector inserted in a vacuum cleaner housing,

[0015] FIG. 2 shows the connector in a longitudinal section turned through 90° about the longitudinal axis of the connector with respect to the longitudinal section shown in FIG. 1 and

[0016] FIG. 3 shows a plan view of the connector.

[0017] A vacuum cleaner has a vacuum cleaner housing 1 that for example, forms the lower part of the complete housing of the vacuum cleaner. The vacuum cleaner housing comprises a wall 2 to which a wall 3 is connected at an angle. The wall 3 serves for example as the front apron of the vacuum cleaner below which the user can grip to lift up the vacuum cleaner. Inside the vacuum cleaner housing 1 a filter bag 4 is affixed directly behind the wall 2 as a dust space. A filter cardboard 5 extends in the vicinity of the wall 2.

[0018] An end piece 7 of a connector 8 projects into an opening 6 of the filter cardboard 5. At its free end the end piece 7 has a sealing cone 9 which is exactly the same size as the opening 6 and ends approximately flush with the side facing the inside of the filter bag 4 so that it does not project into the filter bag 4.

[0019] The end piece 7 also has a circumferential sealing lip 10 which ensures that the dust space with the filter bag 4 is sealed towards the outside.

[0020] The connector 8 has a connecting piece 11 with which it is connected to a suction hose. The connecting piece 11 becomes the end piece 7 and penetrates through the outer wall 3. It thus imparts stability to the housing apron formed by the wall 3.

[0021] The connector 8 is held on the side of the wall 3 facing the wall 2 by means of catch lugs 12 (FIG. 2) which are attached to the outside of catch hooks 13. The catch hooks 13 serve as gripping elements so that the connector 8 can be withdrawn from the opening 6.

[0022] The catch hooks 13 interact with the sealing lip 10 such that the connector 8 is fixed slip-free between the walls 2 and 3. In order that the catch hooks 13 can be simply pressed together during removal of the connector 8 from the vacuum cleaner housing, gripping recesses 14 are arranged on the catch hooks 13. When the catch hooks 13 are pressed together by pressing on the gripping recesses 14, the catch hooks 12 are moved to a distance apart from one another which is less than the diameter of the opening for the connector 8 in the wall 3. The connector 8 can then be pulled out from the walls 2 and 3, exposing the opening 6.

[0023] At the free end of the connector 8 said connector is detachably or non-detachably connected in an inherently known fashion to an end piece of a suction hose. A detachable connection between the connector 8 is known for example from DE 42 40 913 A1.

[0024] The invention provides a connector 8 for a vacuum cleaner housing which is held between walls 2 and 3 of the vacuum cleaner housing. The wall 3 forms a front apron of the vacuum cleaner and can be gripped from its underside by a user such that it is suitable for carrying said vacuum cleaner.

[0025] The connector 8 is fixed between the walls 2 and 3 by means of a sealing lip 10 and the catch lugs 12. In this case, the connector 8 with a sealing cone 9 dips into a filter cardboard 5 such that the filter bag 4 can be removed even when the connector 8 is inserted.
