Suction Apparatus

Abstract

A suction apparatus includes a housing, an electric motor for generating an air flow, wherein the housing has an air inlet by way of which the air flow can enter the housing and an air outlet by way of which the air flow can exit the housing. The suction apparatus further includes at least one cyclone chamber, a collection container, and a filter element. The suction apparatus has at least one air-directing device for directing the air flow within the cyclone chamber.

1 . A suction apparatus comprising:
 a housing having an air inlet and an air outlet;   an electric motor configured to generate an air flow that enters the housing through the air inlet and exits the housing through the air outlet;   at least one cyclone chamber;   a collection container;   a filter element; and   at least one air-directing device configured to direct the air flow within the cyclone chamber.   
     
     
         2 . The suction apparatus according to  claim 1 , wherein the air-directing device at least partially surrounds the filter element so as to at least partially obstruct the filter element. 
     
     
         3 . The suction apparatus according to  claim 1 , wherein, relative to a radial direction to a housing axis, the air-directing device is disposed between the filter element and the collection container. 
     
     
         4 . The suction apparatus according to  claim 1 , wherein, relative to a housing axis, the air-directing device is disposed coaxially between the filter element and the collection container. 
     
     
         5 . The suction apparatus according to  claim 1 , wherein the air-directing device has a substantially circular cross section. 
     
     
         6 . The suction apparatus according to  claim 1 , wherein the air-directing device comprises at least one air-directing element configured to direct the air flow, the air-directing element disposed relative to the filter element. 
     
     
         7 . The suction apparatus according to  claim 6 , wherein the air-directing element has an actuation angle in a range of from 15° to 35° relative to an air-directing axis. 
     
     
         8 . The suction apparatus according to  claim 7 , wherein the range of the actuation angle is from 20° to 30°. 
     
     
         9 . The suction apparatus according to  claim 1 , wherein the air-directing device includes at least one frame element configured to increase a stability of the air-directing device. 
     
     
         10 . The suction apparatus according to  claim 1 , wherein the air-directing device has at least one connection element configured to connect the air-directing device to at least one of the housing, the collection container, and the filter element. 
     
     
         11 . The suction apparatus according to  claim 10 , wherein the air-directing device includes at least one air-directing element disposed on the at least one connection element. 
     
     
         12 . The suction apparatus according to  claim 6 , wherein:
 the at least one air-directing element includes a plurality of air-directing elements, and   the air-directing device includes at least one frame element configured to increase a stability of the air-directing device and to connect the plurality of air-directing elements.   
     
     
         13 . The suction apparatus according to  claim 12 , wherein the air-directing elements are disposed at a mutual spacing in a range of from 15 mm to 35 mm relative to one another. 
     
     
         14 . The suction apparatus according to  claim 13 , wherein the mutual spacing is from 20 mm to 30 mm. 
     
     
         15 . The suction apparatus according to  claim 10 , wherein the air-directing device comprises at least one further connection element configured to connect the at least one air-directing element and/or the air-directing device to at least one of the collection container and the filter element. 
     
     
         16 . An air-directing device configured to direct air flow within a cyclone chamber of a suction apparatus, which includes a housing having an air inlet and an air outlet, an electric motor configured to generate the air flow that enters the housing through the air inlet and exits the housing through the air outlet, the cyclone chamber, a collection container, and a filter element, the at least one air-directing device comprising:
 at least one air-directing element configured to direct the air flow within the cyclone chamber.
