Description
Technical Field
The invention relates to a suction device and an air guide for such a suction device.
Background
DE 102016224105 a1 discloses a suction appliance having a housing, in which a motor for generating an air flow is arranged, at least one cyclone chamber and a filter element, wherein the housing has an air inlet and an air outlet.
Disclosure of Invention
The invention proceeds from a suction appliance having a housing, a motor for generating an air flow, at least one cyclone chamber, a collecting container and a filter element, wherein the housing has an air inlet via which the air flow can enter the housing and an air outlet via which the air flow can leave the housing. It is proposed that the suction device has at least one air guide for guiding an air flow in the cyclone chamber.
The invention relates to a suction device having at least one air-guiding device, by means of which a flow of air can be guided and/or controlled in a targeted manner in a cyclone chamber. Thereby, the efficiency for separating particles and/or liquid from the air stream may be increased.
The suction appliance is configured for collecting and separating material particles and/or liquid from the air flow. An air flow is generated by means of an electric motor. The air flow can reach the housing via the air inlet, wherein the air flow is guided into the collecting container by means of the first air channel. The collection container is designed to collect material particles and/or liquid, wherein the collection container is detachably connected to the housing of the suction device. The air flow passes through the filter element and exits the housing through the air outlet. The filter element is arranged in the cyclone chamber and is in particular detachably connected to the housing. The suction device can thus be adapted to different fields of application. Depending on the desired particle size, filter elements adapted to have a specific pore size may be used which both effectively separate particles from the air stream and allow the maximum air stream to pass through. Furthermore, the filter element can also be advantageously replaced in the event of damage, which ensures a high filter performance of the suction appliance over its service life.
The air inlet and the air outlet of the suction appliance can be arranged on sides facing away from one another. The term "sides facing away" is also to be understood to mean, in particular, sides of the suction device which are oriented substantially perpendicularly to one another or substantially opposite sides.
By "air flow" is to be understood, in particular, a particle flow, a fluid flow and/or a gas flow moving through the suction device in the forward direction. The "forward direction" of the air flow is to be understood in particular as meaning the flow direction of the air flow in the switched-on state of the suction appliance. The forward direction is directed substantially from the air inlet of the suction device in the direction of the air outlet of the suction device. For generating the air flow, an electric motor is advantageously used, which is designed to drive at least one ventilation unit. The ventilation unit can be designed, for example, as a radial blower or as an axial blower.
A "cyclone chamber" is to be understood to mean, in particular, a region of the suction apparatus in which material particles and/or fluid particles are separated from the air flow by a centrifugal force separation device. Advantageously, the air flow is at least partially tangentially directed into the cyclone chamber. Preferably, the airflow is directed in a circular path at least partially within the cyclone chamber. In particular, the air flow is guided in the cyclone chamber at least partially in a circular path around the filter element.
The filter element is advantageously designed for filtering material particles and/or fluid particles as they flow out of the cyclone chamber. In particular, the cyclone chamber is at least partially delimited by the filter element. Preferably, the cyclone chamber is at least partially designed as a hollow cylinder, wherein in particular the outer diameter of the hollow cylinder is formed by the collecting container and the inner diameter of the hollow cylinder is formed by the filter element. The filter element can be designed, for example, as a pleated filter. In particular, the outer surface of the pleated filter corresponds to at least twice the outer circumference of the pleated filter. The filter element is in particular detachably connected to the housing. The connection of the filter element to the housing can be a screw connection, a clamping connection, a snap connection, a hook connection or a bayonet connection. For example, a bayonet connection makes it possible to connect the filter element to the suction device housing both easily and reliably.
The air guide device is designed in such a way that it guides the air flow in the cyclone chamber and the auxiliary air flow passes around the filter element in a circular path. An air guide is arranged in the cyclone chamber for preventing the filter element from being impinged upon by the air flow, in particular directly. The air guiding means achieve this by: the air flow is at least partially deflected from the filter element by means of the air guiding device. Thereby, at least a first component of the air flow is directed to the air outlet via the filter element. At least a second component of the air flow is deflected by the air guiding means. Furthermore, the air guiding device is configured for assisting the air flow in the cyclone chamber. By arranging the air guiding means inside the cyclone chamber, the air flow, in particular at least a second component of the air flow, is at least partially directed from the filter element onto a circular path around the filter element. The air guiding device at least partially guides the air flow, in particular at least a second component of the air flow, away from the filter element and in the direction of the circular path. Thereby assisting the circular path of the air flow in the cyclone chamber. The air guide device can improve the function of the centrifugal force separation mechanism. The separation of the material particles and/or fluid particles is improved as the air flow is directed longer in a circular path.
In one embodiment, the air guiding device at least partially surrounds the filter element for at least partially shielding the filter element. The air guide device may surround the filter element in a cage-like manner. Furthermore, it is conceivable for the air guiding device to at least partially surround the filter element. At least partial shielding of the filter element can be achieved, at least a part of the filter element, in particular a section, in particular a surface, being shielded by the air guiding device. This increases the separation of material particles and/or fluid particles from the air flow and increases the service life of the filter element during operation of the suction device. The filter element is protected by the air flow, in particular directly against the flow, by means of at least partial shielding. As explained above, the air guide device deflects at least a second component of the air flow from the filter element and guides the air flow onto a circular path. Thereby, the air guiding means at least partially shields the filter element. The air guiding device is preferably arranged around the filter element in the circumferential direction. Alternatively, it is also conceivable for the air guide to at least partially cover the lower side or the upper side of the filter element.
In one embodiment, the air guiding device is arranged between the filter element and the collecting container in a radial direction with respect to the housing axis. The housing of the suction device is substantially cylindrical in shape, so that at least one longitudinal axis of the housing forms the housing axis. The air guide device is arranged in the radial direction away from the housing axis between the filter element and the collection container. This makes it possible for the air flow to be guided in a circular path in the cyclone chamber.
In one embodiment, the air guiding device is arranged coaxially with respect to the housing axis between the filter element and the collection container. In this embodiment, the filter element is arranged on the housing axis. The collection container is substantially cylindrical in configuration and is arranged coaxially to the housing axis. The air guide is arranged coaxially to the housing axis. Furthermore, an air guide is arranged coaxially between the filter element and the collecting container.
In one embodiment, the air guiding device is arranged on the filter element. The air guide is arranged on the filter element in such a way that at least one free end of the air guide terminates in at least one free end of the filter element. By "terminating" is understood here that the free end of the air guiding device has substantially the same axial height relative to the housing axis as the free end of the filter element. The air guide device can be detachably connected to the filter element. It is also conceivable that the air guiding device is connected to the filter element substantially non-detachably. As used herein, "substantially non-detachable" is understood to mean substantially not easily removable from the housing by a user. It is also conceivable for the air guiding device to be connected to the housing, in particular detachably.
In one embodiment, the filter element projects in an axial direction relative to the housing axis at least partially beyond the air guiding device. In this case, at least one free end of the filter element can project beyond the at least one free end of the air guide device in the axial direction relative to the housing axis by a range of 5mm to 30mm, in particular 10mm to 25 mm.
In an alternative embodiment, the air guiding device projects at least partially beyond the filter element in an axial direction relative to the housing axis. In this case, at least one free end of the air guide device can project beyond the at least one free end of the filter element in the axial direction relative to the housing axis in the range from 5mm to 30mm, in particular from 10mm to 25 mm.
In one embodiment, the air guiding device has a substantially circular cross-section. Here, "substantially circular" is also to be understood as meaning oval, annular or disk-shaped. The air guide device has an inscribed circle diameter in the range from 100mm to 175mm, in particular from 110mm to 165mm, in particular from 125mm to 155 mm. Furthermore, the air guiding device has a circumscribed circle diameter in the range from 100mm to 185mm, in particular from 115mm to 175mm, in particular from 125mm to 160 mm.
In one embodiment, the air guiding device has at least one air guiding element for guiding the air flow, wherein the air guiding element is arranged relative to the filter element. The air guiding element is configured for guiding the air flow in a circular path within the cyclone chamber. For this purpose, the air-guiding element can be shaped as a cuboid, a wing, a sheet or a droplet. It is also conceivable for the two free ends of the air guiding element to be designed as trapezoids with rounded corners. The air guiding element may have an axial length in the range of 90mm to 160mm, in particular 100mm to 150mm, in particular 110mm to 140 mm. The axial length of the air guiding element is here the distance relative to the housing axis, i.e. in the axial direction along the housing axis.
In one embodiment, the air guiding element has an angle of attack in the range of 15 ° to 35 °, in particular 20 ° to 30 °, with respect to the air guiding axis. The air guide axis may be arranged substantially perpendicular to the housing axis. It is also conceivable for the air guide axis to be arranged additionally at an angle to the housing axis. By means of an angle of attack in the range from 15 ° to 35 °, in particular from 20 ° to 30 °, relative to the air guide axis, it is possible for the air guide element to guide the air flow in the cyclone chamber onto a circular path and at the same time to enable effective screening of the filter element. If a plurality of air guiding elements are provided, these may have the same angle of attack or different angles of attack.
In one embodiment, the air guiding device has one or more frame elements for increasing the stability of the air guiding device. The frame element is designed in such a way that it substantially maintains the shape stability of the air-guiding device in every operating state of the suction device. In particular, the frame element can hold the air flow guiding device in the cyclone chamber in a shape-stable manner when the suction appliance is in operation, irrespective of the strength of the air flow. Here, "shape-stable" is understood to mean that the shape is maintained even when an external force is applied. The air guiding element is connected with the frame element. It is thereby possible for the frame element to arrange the air guiding element with an angle of attack. It is conceivable for the air-guiding element to be connected to the frame element in a form-fitting, force-fitting and/or material-fitting manner. Furthermore, it may be that the frame element is integral with the air guiding element. Furthermore, it may be provided that the air guiding device has a further frame element for stabilization in the circumferential direction relative to the housing axis. The further frame element may be connected with the air guiding element. It is conceivable that the further frame element and the air guiding element are integral.
In one embodiment, the air guiding device has at least one connecting element for connecting the air guiding device to the housing, the collecting container and/or the filter element. The connecting element can in this case connect the air-guiding device to the housing, the collecting container and/or the filter element in a detachable or substantially non-detachable manner, wherein "substantially non-detachable" is to be understood as explained above. The connecting element can connect the air-guiding device to the housing, the collecting container and/or the filter element in a force-fitting, form-fitting and/or material-fitting manner. The connecting element can have a receiving element for receiving the fastening element for the connection. By means of the fastening element and the receiving element, the air-guiding device can be connected to the housing, the collecting container and/or the filter element. For example, the receiving element can be designed as a receiving opening, while the fastening element can be designed as a screw. The screw can then connect the connecting element to the housing, the collecting container and/or the filter element by means of the receiving opening. It is also conceivable for the connecting element to have at least one holding element for connecting the air-guiding device to the housing, the collecting container and/or the filter element. The holding element can thus be designed, for example, as a catch. It is also possible for the connecting element to be formed as a clamping ring in order to connect the air-guiding device to the housing, the collecting container and/or the filter element by means of a clamping connection. For this purpose, the collecting container can have at least one receiving element, for example in the form of a receiving ring.

In one embodiment, the air guiding element is arranged on the connecting element. The air guiding element can be connected to the connecting element by means of the frame element in a non-positive, form-fitting and/or material-fitting manner. The air guiding element can thus be connected to the connecting element at least by means of a clamping connection, a snap connection, a bayonet connection and/or a snap-lock connection via the frame element. It is also conceivable that the air guiding element, the frame element and the connecting element are integral.
In one embodiment, the air guiding device has a plurality of air guiding elements, and the frame element is configured for connecting the plurality of air guiding elements. The number of the plurality of air guiding elements may be in the range from 2 to 30, in particular from 2 to 25. The frame element is designed in such a way that it can receive and connect a plurality of air guiding elements. The frame element can connect the air guide elements in a force-fitting, form-fitting and/or material-fitting manner. For connecting the frame element to the plurality of air guiding elements, a clamping connection, a snap connection or a bayonet connection may be considered. It is also possible for the frame element to be formed in one piece with a plurality of air guiding elements. The frame element may preferably be arranged with a plurality of air guiding elements in the circumferential direction of the air guiding device. The air guiding elements may each have an angle of attack in the range from 15 ° to 35 °, in particular from 20 ° to 30 °, with respect to the air guiding axis. It is conceivable that each air guiding element of the plurality of air guiding elements has a different angle of attack relative to the air guiding axis in the range of 15 ° to 35 °, in particular 20 ° to 30 °. Furthermore, the connecting element is designed to connect the plurality of air guiding elements also to the housing, the collecting container and/or the filter element.
In one embodiment, the air guiding elements are arranged at a distance in the range from 15mm to 35mm, in particular from 20mm to 30mm, from one another. It is conceivable that the plurality of air guiding elements each have a different spacing in the range from 15mm to 35 mm. Due to the spacing of the air guiding elements, it is possible to effectively separate material particles and/or fluid particles in a way that: the air guide element increases the shielding for preventing in particular direct flow against the filter element.
In one embodiment, the plurality of air guiding elements are arranged substantially in the shape of a cylinder jacket. The air guiding elements are arranged on the frame element in such a way that they form a kind of cylinder liner. The cylinder liner has an inscribed circle diameter in the range from 100mm to 175mm, in particular from 110mm to 165mm, in particular from 125mm to 155 mm.
