SUCTION DEVICE, ESPECIALLY FOR THE HOUSEHOLD

The present invention relates to a suction device which is particularly suitable for use in the household is.

Various types of suction fans are currently known, which generally consists of one of an electric motor in Rotation offset impeller consist. In the conventional Suction fans, the impeller is housed in a screw, which consists of a block and a Line for the discharge of the sucked air to the outside is provided. In these execution forms are stored with the time inside the screw in the sucked in air Existing grease and dirt particles around the impeller

around off. As a result of these dirt deposits, the suction fan emits unpleasant smells after a certain time and becomes unusable because it can no longer fulfill its originally intended task.

The fat and dirt deposits also have a negative impact on the operation and efficiency of the Suction fan, and partly lead to its irrevocable Damage so that the owner of the whole. Device needs to be replaced.

The aim of the present invention is to eliminate the above-mentioned disadvantages by providing a especially suitable for the household, practical and functional suction device in which the screw and the impeller can also be cleaned inside.

Another object of the present invention is in creating an absolutely hygienic suction device that completely eliminates unpleasant odors eliminated.

The present invention also aims to provide a suction device which is light and quick disassembled into its component parts and therefore fully checked for potential. Pre-tax damage gene,

Another object of the present invention is to provide a suction device which is easily made of commercially available elements and is competitively priced.

These and other goals, which are clearly evident from the following description, are achieved by a suction device that is particularly suitable for the household, consisting of a base that can be attached to an outlet opening, an impeller set in rotation by a motor, and an outer shell for the accommodation of this impeller and direses motor that can be mounted on this base, characterized in that this outer shell consists of two half-shells which can be put together and taken apart.

Other features and advantages will appear more clearly from the following description of a preferred embodiment a suction device particularly suitable for the household with reference to the attached examples Drawings. It shows:

Fig. 2 is a side view of the suction device;

Fig. 3 shows a cross section along the straight line III-III in Fig. 1;

Fig. 4 is a perspective view of a detail of the

bond between the two half-shells of the outer shell the suction device.

With reference to the above figures, the invented " • Appropriate suction device 1 from a base 2 with a substantially rectangular base area, which at their corner points have through holes 3- for fastening this pad on a wall or the like. Has an outlet opening. From a middle section this base 2 is a discharge line 4 from which for example with the aid of screws 5 the junction 6 of a helical outer shell 7 is attached.

In the interior of this outer shell 7, a suction wheel 8 is arranged, which is also in the interior of the envelope 7 provided electric motor 9 is set in rotation. '. ·

The sheath 7 consists of two half-shells 7a and 7b, which abut one another along an edge 10 which, with reference to this envelope 7, is in a central, in .wesserlichen ^ is arranged perpendicular to the axis of rotation of the suction wheel 8 plane. The half-shell points to the contact edge 10 7a has a projection 11, which extends along the entire contact edge and is supported by a corresponding corresponding, provided on the contact edge 10 of the half-shell 7b receptacle 12 is received. In this way and Way there is a clamping element for the connection

609819/0821

2546974

the half-shell 7a with the half-shell 7b.

In order to achieve a stable connection between the half-shell 7a and the half-shell 7b, a groove 13a or 13b is provided in the vicinity of the edge 10 both on the half-shell 7a and on the half-shell 7b, which is parallel to the edge.10 on the the entire length of the same extends. The arms 14a and 14b respectively engage in these grooves 13a and 13b

one along the entire edge 10 extending connection se learn te s 14 with a U-shaped cross-section.

The connecting element 14, which is preferably made of rubber or some other elastic material, is also held in place by two pins 15 and 16, which are arranged at the two free ends of the connecting element 14 and worked out of the confluence of the Stftes sleeve 7. The two pins 15 and 16 each consist of two halves provided on the half-shell 7a and on the half-shell 7b. It should also be noted that the connecting element 14 has two holes 17 and 18 at its two free ends, into which these pins 15 and 16 are inserted.

For the sake of completeness, it must still be said that the half-shell 7b has a projection in a central section 20 has, which develops axially to the half-shell 7b, and in which the motor 9 is housed. the Half-shell 7a, on the other hand, has a central section

609819/0821

a suction opening 21 which is arranged axially to the suction wheel 8 is.

The operating mode of the suction device is based on the above description clearly shows which is obviously cleaned quickly inside and in particular in the zone of the suction wheel 8 can be. To do this, it is sufficient to loosen the screws 5 in order to free the entire outer shell from the base 2. Only the ends of the connecting element need to be on it 14 can be released from the pins 15 and 16, and the sheath 7 can be opened completely by separating the half-shells 7a and 7b from one another. After this process, the Zone of the suction wheel completely checked and, if necessary, carefully cleaned by all possibly in the Removed internally deposited grease and dirt particles. Obviously, this process takes little time and is extremely easy to carry out. For assembly, the same steps are reversed repeated.

Numerous changes can be made to the invention thus configured and variants can be made without thereby exceeding the scope of the invention.

In addition, all components can be replaced by others, technically equivalent elements are replaced.

In practice, depending on the requirements any materials and dimensions can be selected,
