From the US 2005/0050677 A1 a vacuum cleaner with a suction material container is known, the suction material container being detachably connected to a suction head of the vacuum cleaner and wherein the suction material container has a pivotably mounted handle.

From the EP 3448218 B1 a vacuum cleaner is known, comprising a container, a suction unit, an air ducting unit and an exhaust air unit, wherein the exhaust air unit comprises a collecting chamber defining a substantially annular air flow volume which is concentric to the suction unit and which is positioned around one or more outlet openings of the suction unit in order to Collect air, and direct collected air to an outlet port of the collection chamber. The exhaust unit further comprises two opposing exhaust ducts, each of the two ducts surrounding a respective portion of the plenum chamber and having an inlet end in correspondence with the outlet opening of the plenum chamber and a respective outlet end which is opposite to the inlet end in order to discharge air flowing through the suction unit is sucked in.

The invention is based on the object of providing a suction device mentioned at the outset which, with a compact design, can be used in a variety of ways and which can be operated easily and conveniently.

This object is achieved according to the invention in the suction device mentioned at the outset in that the suction device comprises a pipe element with an adapter device, the adapter device being or being releasably connectable to a suction connection of the suction device in a fluid-effective manner for performing a suction process and the adapter device for performing a blowing process with the first air outlet is fluidly releasably connectable or is connected, and wherein by means of at least one wall element of the adapter device, an air inlet opening of the second channel for supplying process air from the suction fan device to the second air outlet is closed when the adapter device is properly connected to the first air outlet.

As a result, a decoupling of process air through the second air outlet can be blocked or released as a function of whether the adapter device is connected to the first air outlet or not. If the adapter device is properly connected to the first air outlet, the process air is extracted exclusively via the first air outlet, the process air then being extracted from the suction head via the first air outlet, in particular with an increased outflow speed and / or with an increased pressure. In this way, for example, an effective blowing function can be implemented on the suction device.

If the adapter device is separated from the first air outlet, the second air outlet is released. The process air is then decoupled from the suction head both via the first air outlet and via the second air outlet. An air flow of the decoupled process air is thereby distributed to the first air outlet and to the second air outlet, so that an outflow speed and / or a pressure of the decoupled process air at the first air outlet or at the second air outlet is reduced. Through this unwanted blowing on an operator of the suction device during operation is reduced.

The suction device according to the invention can thus be used in a particularly versatile and comfortable manner by an operator.

When the adapter device is separated from the first air outlet, the second channel is in particular completely released and / or completely opened. If the adapter device is properly connected to the first air outlet, the second channel is in particular completely blocked and / or completely closed, so that in particular no process air can be extracted by means of the second air outlet.

In principle, it is also possible for the adapter device to implement an intermediate state in which the air inlet opening of the second channel is at least partially released and / or partially opened.

In principle, it is also possible that the air inlet opening of the second channel can be closed or released by means of a nozzle element, the nozzle element being arranged, for example, on the suction head or on the adapter device.

It is also possible that the air inlet opening of the second channel can be closed or released by arranging an accessory element of the suction device within the first channel. For example, the accessory element is a nozzle element or a crevice nozzle for use with the suction device, which can be arranged within the first channel. If the accessory element is arranged within the first channel, the air inlet opening of the second channel is blocked by means of the accessory element.

It can be favorable if the air inlet opening of the second channel is arranged in a transition area between a connecting channel of the channel device and the second channel, with process air being able to be supplied from the suction fan device to the first channel and / or the second channel by means of the connecting channel. In this way, the second channel can be fluidically separated from the connecting channel in a technically simple manner.

It can be favorable if the air inlet opening of the second channel is released when the adapter device is separated from the first air outlet. This results in, for example, an automatic transition to an operating mode in which the process air is decoupled via the first air outlet and the second air outlet when an operator separates the adapter device from the first air outlet, which enables convenient operation of the suction device.

It can be advantageous if the at least one wall element of the adapter device has a curved shape and / or if the at least one wall element lies in a geometric cylinder section. The at least one wall element can thereby be connected, for example, in a technically simple manner to a cylindrical hose element, whereby the adapter device can be arranged or formed on a cylindrical hose element in a technically simple manner.

It can be favorable if the suction device comprises a connecting device, by means of which the adapter device can be releasably fixed and / or releasably latched to the first air outlet.

In particular, it can be provided that the suction device comprises a connecting device, by means of which the adapter device can be releasably fixed and / or releasably latched on the suction connection.

In particular, it can be provided that at least one rib element for supporting and / or guiding the adapter device is arranged on the first air outlet and / or on the first channel, and in particular that the at least one rib element is oriented at least approximately parallel to a first longitudinal center axis of the first channel is.

For example, the second channel within the suction head is in fluid communication with a connecting channel for supplying process air from the suction fan device to the first channel and / or the second channel when the adapter device is separated from the first air outlet.

For example, the second channel within the suction head is closed in a fluid-tight manner with respect to a connecting channel for supplying process air from the suction fan device to the first channel and / or the second channel in the suction head when the adapter device is properly connected to the first air outlet.

For example, the first channel within the suction head is in fluid communication with a connecting channel for supplying process air from the suction fan device to the first channel and / or the second channel when the adapter device is separated from the first air outlet.

For example, the first channel within the suction head is in fluid communication with a connecting channel for supplying process air from the suction fan device to the first channel and / or the second channel when the adapter device is properly connected to the first air outlet.

The aforementioned object is also achieved according to the invention in the aforementioned suction device in that a smallest angle between a first longitudinal center axis of the first channel and a second longitudinal center axis of the second channel is at least 40 ° and / or at most 70 °.

It is thereby possible to reduce a torque exerted on the suction device and / or on the suction head when process air is decoupled from the suction head during operation. This makes it possible to reduce undesirable movements and, in particular, undesirable rotary movements of the suction device during operation. This enables the suction device to be operated as conveniently as possible.

As a result, the suction device can also be used particularly comfortably, for example, when it has reduced static friction with respect to a subsurface, for example because the subsurface is smooth or because the suction device is equipped with rollers for movement on the subsurface. In these situations too, the suction device according to the invention can reduce an undesired (rotary) movement which results from the extraction of process air.

In particular, it can be provided that a smallest angle between the first longitudinal center axis of the first channel and the second longitudinal center axis of the second channel is at least 50 ° and / or at most 60 °. In this way, a torque that occurs when process air is decoupled onto the suction device can be further reduced.

It can be favorable if a smallest angle between a main flow direction of process air guided through the first channel and a main flow direction of process air guided through the second channel is at least 40 ° and / or at most 70 ° and in particular at least 50 ° and / or does not exceed 60 °.

For example, a first longitudinal center axis of the first channel and a second longitudinal center axis of the second channel lie at least approximately in a common plane, the plane being oriented transversely and in particular perpendicular to a longitudinal center axis and / or to a height direction of the suction device.

For example, a main flow direction of process air guided through the first channel and a main flow direction of process air guided through the second channel lie at least approximately in a common plane, the plane being transverse and in particular perpendicular to a longitudinal center axis and / or to a vertical direction of the suction device is oriented.

For example, an outer contour of the first air outlet is at least approximately circular.

It can be favorable if the first air outlet and the second air outlet are spaced apart from one another in the circumferential direction of the suction head, and in particular if the smallest distance between the first air outlet and the second air outlet is at least 1 cm and / or at most 7 cm. The occurrence of a torque during the coupling of process air can thereby be further reduced.

For example, a first center point of an outer contour of the first air outlet and a second center point of an outer contour of the second air outlet are at least approximately at the same height with respect to a height direction of the suction device.

For example, a lower end of the at least first air outlet and a lower end of the second air outlet are at least approximately at the same height with respect to a height direction of the suction device.

For example, an upper end of the first air outlet and an upper end of the second air outlet are at least approximately at the same height with respect to a height direction of the suction device.

For example, the second air outlet has a cross-sectional area that is at least 10% and in particular at least 15% and in particular at least 20% larger than the first air outlet. As a result, process air can be extracted over an enlarged cross-sectional area, as a result of which a flow velocity and / or a pressure of the extracted air is reduced.

For example, an outer contour of the second air outlet is essentially rectangular.

For example, an outer contour of the second air outlet lies at least in sections in a geometric rectangle.

For example, at least three of four edge sections of the outer contour of the second air outlet lie in a geometric rectangle.

For example, a fourth edge section of the outer contour of the second air outlet has a first section and a second section adjoining the first section, the second section being oriented transversely to the first section.

For example, at least one edge section of the outer contour of the second air outlet is oriented transversely and in particular perpendicular to a height direction of the suction device.

For example, an edge section of the outer contour of the second air outlet facing the first air outlet is designed in a straight line.

It can be favorable if the first channel and the second channel have fluidically separated or fluidically separable flow spaces for air. As a result, the second channel can be fluidically separated from the first channel within the suction head, so that, for example, process air cannot be decoupled via the second channel.

It can be advantageous if a flow cross section of the first channel is at least approximately constant. In this way, for example, the connection of the adapter device to the first air outlet can be implemented in a technically simple manner.

It can be favorable if a flow cross section of the second channel widens towards the second air outlet, and in particular if the flow cross section of the second channel is greatest at an end of the second air outlet facing the second air outlet and / or at an end facing away from the second air outlet of the second channel is smallest. A flow speed of process air coupled out through the second channel can thereby be reduced.

In particular, it can be provided that the channel device comprises a connecting channel for establishing a fluid-effective connection between an outlet of the suction fan device and the first air outlet and / or the second air outlet, with air to be coupled out of the suction head onto the first channel and / or onto the first channel by means of the connecting channel the second channel is split or can be split. In this way, for example, process air can be fed to the first channel and the second channel at the same time for decoupling.

For example, the connecting channel is arranged in an interior of the suction head.

For example, the connecting channel has a first partial area in which a flow cross section of the connecting channel is at least approximately constant

For example, the connecting channel has a second partial area adjoining a first partial area, the second partial area facing the first channel and / or the second channel, and wherein a flow cross-section of the connecting channel in the second partial area extends to the first channel and / or the second channel expanded and in particular expanded monotonically. In this way, for example, process air can be divided into the first channel and the second channel in a technically simple manner.

For example, the connecting channel surrounds the suction fan device in sections.

For example, the connecting channel has a shape that is curved towards a longitudinal center axis of the suction device, the longitudinal center axis being oriented parallel to a height direction of the suction device.

For example, the connecting channel is arranged between an outlet and / or outlet channel of the suction fan device and the first channel and / or the second channel with respect to a main flow direction of air coupled out from the suction fan device.

For example, a transition area for air is formed between an outlet and / or outlet channel of the suction fan device and the connecting channel.

For example, a transition area for air formed between an outlet and / or outlet channel of the suction fan device and the connecting channel is designed in such a way that a main flow direction of air decoupled from the suction fan device reverses in the transition area and, in particular, reverses by at least approximately 180 °.

In one embodiment, the suction device comprises at least one air guiding element for distributing air to be decoupled from the suction head to the first channel and the second channel, the at least one air guiding element being arranged in the connecting channel or assigned to the connecting channel. The air can be distributed to the first channel and the second channel in a technically simple manner by means of the at least one air guide element.

For example, the at least one air guiding element is oriented transversely to the first channel.

For example, a smallest angle between a longitudinal center axis of the at least one air guiding element and a first longitudinal center axis of the first channel is at least 20 ° and / or at most 50 ° and in particular at least 30 ° and / or at most 40 °.

For example, the at least one air guide element has a shape that is curved towards a longitudinal center axis of the suction device, the longitudinal center axis being oriented parallel to a height direction of the suction device.
