Description

GAS STURDER DEVICE WITH A FLEXIBLE ROTOR BLADE AND GAS STURDER METHOD

TECHNICAL AREA

[0001] The present disclosure relates to a gas swirling device and method for gas swirling, particularly a fan.

STATE OF THE ART

[0002] Conventional fans are normally used to cool, for example, interior spaces by installing a fan on the ceiling, the blades of which are set in motion and a draft is generated in this way. The strength of the draft can be regulated in several stages by increasing or decreasing the speed of movement of the wings.

Typically, conventional fans are made of rigid materials such as wood or plastic. This results in a mostly clunky and heavy design. Furthermore, the fan can only be mounted at suitable locations on the ceiling, which must be suitable for the typically high weight and large size of a conventional fan.

[0004] Furthermore, a conventional fan has a high energy consumption due to the fixed speed levels for regulating the draft.

It is therefore advantageous to provide a gas swirling device that is space-saving, lightweight and energy efficient.

Each example is provided for explanation of the disclosure and is not intended as a limitation of the disclosure. Furthermore, features illustrated or described as part of one embodiment may be present on or in conjunction with others Embodiments are applied to obtain another embodiment. The description is intended to include such modifications and variations.

According to embodiments that can be combined with any embodiment described herein, a gas swirling device is provided. The gas swirling device comprises a drive for generating a rotational speed and a base body which can be rotated about a first axis. The base body can be rotatably connected to the drive. The drive can generate a rotational movement of the base body. The drive can provide the rotational movement in a direction of rotation of the base body. The direction of rotation can be clockwise or counterclockwise. The drive can provide a rotational speed of the base body or the rotational speed of the base body can be controlled by regulating the drive. The drive can be an electric motor. It is to be understood that the drive can be any drive that is suitable for generating a rotational movement. For example, the drive can also be a hydraulic or pneumatic drive or a combination of an electric, pneumatic and/or hydraulic drive.

According to embodiments that can be combined with any embodiment described herein, the drive can include a connection to the base body. The connection can include a driver and an axial bearing, in particular a thrust bearing. Advantageously, this can prevent the total weight of the base body from acting completely on the drive. Accordingly, the durability and service life of the drive are extended and improved.

According to embodiments that can be combined with any embodiment described herein, the first axis can be a substantially vertical axis. Alternatively, the first axis can be a substantially horizontal axis. The terms “essentially vertical” and “essentially horizontal” as used herein are to be understood in such a way that “essentially vertical” can deviate from completely vertical by a maximum of ± 5°, in particular by a maximum of ± 10°, and “ essentially horizontal” from completely horizontal can have a deviation of at most ± 5°, in particular at most ± 10°. Furthermore, the terminology "substantially" can in itself be so be understood that a deviation of ±5%, in particular ±10%, from an exact value is included.

According to embodiments that may be combined with any embodiment described herein, the gas swirling device may include a housing. The drive can be arranged in the housing. The gas swirling device may include one or more devices for mounting the gas swirling device. In particular, the housing can include one or more devices for assembly. For example, the gas swirling device can comprise a screw-fixable plate for attachment to a flat surface such as a ceiling or wall. Advantageously, the housing may be made of an ornamental and/or lightweight material, such as plastic and/or metal.

Advantageously, the gas swirling device can thus be provided in a compact design.

According to embodiments that can be combined with any embodiment described herein, the gas swirling device can be a fan, in particular a ceiling, wall and/or portable fan. The portable fan may include a handheld mount. The portable ventilator may include a control unit, particularly on the hand mount.

According to embodiments that can be combined with any embodiment described herein, the base body comprises a rolling unit rotatable about a second axis. The reel unit includes a flexible rotor blade. The rolling unit is designed to roll up and/or unroll the flexible rotor blade. In particular, the rolling unit is designed to roll out and/or roll in the flexible rotor blade depending on the rotational speed.

According to embodiments that can be combined with any embodiment described herein, the rolling unit can comprise a support structure, in particular a tube, for example a plastic tube, on which the flexible rotor blade is provided. In particular, the flexible rotor blade can be rolled up or rolled up and/or unrolled on the support structure, for example the tube. According to embodiments that may be combined with any embodiment described herein, the second axis may lie in a second plane that is rotated substantially 90° to a first plane in which the first axis lies. In other words, there can be an angle of essentially 90° between the first plane and the second plane (regardless of an assembly state of the gas swirling device). Furthermore, the first axis can extend in a first direction and the second axis can extend in a second direction different from the first direction of the first axis. The first axis can extend in a substantially vertical direction and the second axis can extend in a substantially horizontal direction.

Advantageously, orienting the axes in different directions leads to the flexible rotor blades being rolled out and rolled in without risk. Furthermore, such an arrangement can ensure easier replacement of the rolling units, e.g. for maintenance and/or for the assembly of a rolling unit used for a specific purpose or a flexible rotor blade used.

According to embodiments that can be combined with any embodiment described herein, the body may include multiple rolling units. For example, the base body can comprise two or more rolling units, in particular three or more rolling units, more particularly four or more rolling units or five or more rolling units or six or more rolling units. The base body can include a base plate. The rolling unit or the multiple rolling units can be arranged on the base plate. The plurality of rolling units may be equidistant from each other. For example, the base body can include three rolling units or three rolling units can be arranged on the base plate. In particular, the three rolling units can be arranged as a substantially equilateral triangle. It is to be understood that the multiple rolling units may be arranged according to number, particularly as a polygon. For example, four rolling units can be arranged as a square, in particular as a square, corresponding to five rolling units as a (regular) pentagon and six rolling units as a (regular) hexagon.

According to embodiments that can be combined with any embodiment described herein, the base plate can have any suitable geometric shape. In particular, the base plate can essentially be round, rectangular, triangular or polygonal be. In particular, the shape of the base plate can correspond to a number and arrangement of the rolling units.

According to embodiments that can be combined with each embodiment described herein, the rolling unit can comprise a tensioning device that is tensioned by unrolling the flexible rotor blade. The tensioning device can be designed in such a way that the tensioning device twists when the flexible rotor blade is unrolled. For example, the tensioning device can be selected from a rubber motor, a rotatable spring, in particular a rotatable metal spring, a torsion bar and/or a torsion bar spring. The torsion bar or the torsion bar spring can be made of plastic or contain plastic.

Advantageously, the unrolling of the flexible rotor blade leads to an (additional) twisting of the tensioning device. In other words, energy is stored in the tension device by coasting. The stored energy can be used to roll up the flexible rotor blade. In particular, the stored energy can be used to roll up the flexible rotor blade as a function of the rotational speed. For example, the tensioning device can be triggered when the rotational speed falls below a certain threshold value, so that the flexible rotor blade is rolled up.

According to embodiments that can be combined with any embodiment described herein, the tensioning device can be prestressed or have a prestress. The pre-tension can be adjusted by a regulating element on the reel unit. The regulation element can be connected to the tensioning device. For example, the regulating element can be a tension knob. Advantageously, the pretensioning of the tensioning device can strengthen or simplify the inward or outward rolling up of the flexible rotor blade.

According to embodiments that can be combined with any embodiment described herein, the rolling unit can be detachably connected to the base body, in particular to the base plate. For example, the rolling unit can be connected to the base body via suitable fixing means, such as screws. Additionally or alternatively, the base body can include a holder into which the roller unit can be inserted in such a way that the rolling unit can rotate. For example, the roller unit can be clicked into the holder at two axially opposite ends of the roller unit. The mount can include a bearing, eg a rotary bearing.

[0028] Advantageously, the roller unit can be exchanged. This means that individual roller units can be removed or replaced for maintenance. Accordingly, the durability of the gas swirling device can be improved and it can be operated at low cost.

According to embodiments that can be combined with any embodiment described herein, the connection of the rolling unit to the base body or to the base plate can be height-adjustable. For example, the connection may include one or more members. The multiple members can be slidably connected to each other. Advantageously, an angle of attack of the flexible rotor blade can be regulated via the height adjustability of the rolling unit.

According to embodiments that can be combined with any embodiment described herein, the flexible rotor blade is fully and/or partially unrollable depending on the rotation speed. Depending on the rotational speed, the flexible rotor blade can be completely and/or partially unrolled and/or rolled in. For example, the flexible rotor blade can be rolled out completely and/or partially when the rotational speed exceeds a first threshold value and/or can be rolled in completely and/or partially when a second threshold value is undershot. In particular, the flexible rotor blade can be fully unrolled at a maximum rotation speed. More particularly, the flexible rotor blade can be fully rolled in at a minimum rotation speed. Furthermore, the flexible rotor blade can be rolled out or rolled in according to a rotation speed gradient. For example, the flexible rotor blade can be partially unfurled when the first threshold is exceeded and then further unfurled with an increasing rotational speed gradient until it is fully furled at the maximum speed. Conversely, if the flexible rotor blade falls below a second threshold value, it can be partially rolled up and then further rolled up with a decreasing rotational speed gradient until it is completely rolled up at the minimum speed. According to embodiments that can be combined with any embodiment described herein, the flexible rotor blade can be connected to the rolling unit at a first end. At a second end of the flexible rotor blade opposite the first end, the flexible rotor blade may include a reinforcement. The reinforcement may have or include a weight. The gain can be chosen so that the rotor blade is rolled out at a certain rotational speed. In other words, the rotational speed at which the rotor blade is rolled out and/or rolled in can be determined via a type of amplification. Advantageously, the rolling out or rolling in of the flexible rotor blade can be based on the principle of centrifugal force.

According to embodiments that may be combined with any embodiment described herein, the first rotational speed threshold and the second rotational speed threshold may be dependent on the gain of the flexible rotor blade. For example, the reinforcement can have a weight. The first threshold may be a lower rotation speed when the gain weight is high. The first threshold may be a higher rotation speed when the gain weight is a small value. Furthermore, the first threshold and the second threshold may be the same or different.

Advantageously, the flexible rotor blades can be unfurled when the gas swirling device is in an active state. This can mean that the rotor blades are protected from (negative) external influences such as dust, sunlight, etc. Accordingly, the durability and service life of the gas swirling device, in particular the flexible rotor blades, is extended. Furthermore, the gas swirling device is safer and more compact when the gas swirling device is not in active use.

According to embodiments that can be combined with any embodiment described herein, the flexible rotor blade can be detachably connected to the rolling unit. Advantageously, the flexible rotor blade can thus be easily exchanged without the entire roller unit having to be renewed/exchanged.

The rolling unit, the flexible rotor blade or the flexible material and/or the coating can comprise, for example, a material with fibers that are directed essentially radially outwards. For example, the rolling unit, the flexible rotor blade or the flexible material and/or the coating can comprise or consist of an artificial fur. In particular, the flexible rotor blade or the flexible material and/or the coating can comprise capillary hairs. The capillary hairs can have a length, in particular in a radially outward direction, of between 0.001 mm and 10 mm, in particular between 0.01 mm and 5 mm, more particularly between 0.1 mm and 1 mm.

Advantageously, gases can be absorbed in this way. Also advantageously, solid, liquid and/or gaseous components that are dispersed/mixed in the gas or gas mixture can be bound to the artificial fur and/or the capillary hairs so that they are isolated or filtered from the gas or gas mixture. Accordingly, a dispersion or a gas mixture can be freed from specific components. For example, a gas such as air can be freed from solids dispersed in it, such as microorganisms, virus particles, dust particles, pollen, protozoa, (solid) pollutants, toxins, etc. by being absorbed or bound to the flexible material or the coating . Liquids dispersed in the gas can be, for example, (contaminated) water, oil-based liquids, organic liquids, and/or inorganic liquids. Gases mixed in the gas can be, for example, war gases, tear gases, exhaust gases such as carbon monoxide, and/or narcotic gases.

The gas swirling device can advantageously be used as a gas cleaning device. For example, by mounting in a room, for example in an apartment, existing air can be freed from substances dispersed therein or substances dispersed therein can be depleted. For example, improved room air can be provided. The simultaneous turbulence of the carrier gas can lead to additional cooling of the room. Additionally or alternatively, the gas swirling device can be provided in rooms that need to be cleared of a specific substance, such as a mold infestation in a basement. Furthermore, additionally or alternatively, the gas swirling device can be used to alleviate medical ailments, for example by depleting allergens from the carrier gas in the case of allergy sufferers and/or for Depletion of certain pathogens so that the risk of infection can be reduced and/or eliminated.
