Description

Technical Field

[0001] The present invention relates to a cleaning device for cleaning surfaces, in particular floors, the cleaning device comprising a drive device, a drive shaft that can be driven in a manner to rotate about a rotation axis by means of the drive device, a cleaning roller that can be connected to the drive shaft in a manner that is non-rotatable and detachable, and a fixing device for axially fixing the cleaning roller on the drive shaft, wherein the cleaning roller has a roller body, the roller body has a roller recess extending in the axial direction and a torque transmission link connected to the roller recess in the axial direction, the torque transmission link being passed through by the drive shaft while forming a non-rotatable connection, and wherein the fixing device can be inserted into the roller recess and can be axially fixed on the drive shaft, wherein a stop element of the fixing device comes into contact with a stop surface of the roller body facing away from the torque transmission link. Background Art

[0002] Such cleaning devices are particularly used for cleaning floors in indoor or outdoor areas. These cleaning devices include a drive device, such as an electric motor, which rotates a drive shaft about a rotation axis. At least one cleaning roller is connected to the drive shaft in a rotationally fixed and detachable manner. The cleaning roller can, for example, be designed in the form of a brush roller, which carries a brush structure formed by a plurality of cleaning brushes on its outer side. Alternatively, the cleaning roller can have a cleaning backing, such as a cleaning nonwoven or a cleaning fabric.

[0003] The cleaning roller comprises a roller body having a roller recess extending axially with respect to the rotational axis of the drive shaft and a torque transmission element axially coupled to the roller recess. The drive shaft passes through the torque transmission element, forming a rotationally fixed connection. Torque can be transmitted from the drive shaft to the roller body via the torque transmission element. To axially secure the cleaning roller to the drive shaft, a securing device can be inserted into the axial roller recess and axially secured to the drive shaft, wherein a stop element of the securing device comes into contact with a stop surface of the roller body facing away from the torque transmission element. This ensures that the cleaning roller cannot be accidentally detached from the drive shaft.

[0004] A cleaning device of the type mentioned above is known from DE 10 2021 128 035 A1. In this cleaning device, a fixing device can be screwed to a drive shaft. However, screwing the fixing device requires either a right-hand thread or a left-hand thread, depending on the direction of rotation of the cleaning roller. This makes handling the cleaning device more difficult when replacing the cleaning roller, particularly when the cleaning device has at least two cleaning rollers whose directions of rotation point in opposite directions. Summary of the Invention

[0005] SUMMARY OF THE INVENTION It is therefore an object of the present invention to improve a cleaning device of the type mentioned in the introduction so that it has simpler handling when replacing the cleaning roller.

[0006] In a cleaning device of the generic type, this object is achieved according to the invention in the following manner, namely, the fixing device has a guide body, in which a rotating body is held in a manner that it can rotate about the rotation axis of the drive shaft and cannot move axially, wherein the rotating body has at least one holding arm, which cooperates with a guide link of the guide body and can be moved back and forth between a locked position and a released position by rotating the rotating body relative to the guide body, and the holding arm has a locking element, which in the locked position of the holding arm is sunk into a recess in the drive shaft, and in the released position of the holding arm is spaced apart from the recess.

[0007] To secure at least one cleaning roller to the drive shaft, the cleaning device according to the present invention uses a fixing device comprising a guide body and a rotor. The rotor is held in the guide body so as to be rotatable about the rotation axis of the drive shaft and immovable in the axial direction, and has at least one retaining arm with a latching element. The retaining arm cooperates with the guide link of the guide body so that the retaining arm can move back and forth between a latching position and a release position when the rotor rotates. In the latching position, the latching element of the retaining arm sinks into a recess in the drive shaft, while in the release position of the retaining arm, the latching element releases the recess. In the latching position of the retaining arm, the fixing device is immovably held in the drive shaft in the axial direction, while in the release position of the retaining arm, the fixing device can move axially relative to the drive shaft. This allows the cleaning roller and the fixing device to be separated from the drive shaft as soon as at least one retaining arm is in its release position, while when the retaining arm is in its latching position, the cleaning roller and the fixing device are axially fixed to the drive shaft.

[0008] To move the at least one retaining arm from the locked position to the released position, the rotor only needs to be twisted relative to the guide body in the first rotational direction, preferably by 90°. To move the at least one retaining arm from the released position to the locked position, the rotor only needs to be twisted relative to the guide body counter to the first rotational direction. The rotational direction of the rotor is independent of the rotational direction assumed by the cleaning roller during operation of the cleaning device. This facilitates the user's handling of the cleaning device when replacing the cleaning roller, as the user does not need to pay attention to the existing rotational direction of the cleaning roller during operation of the cleaning device.

[0009] Advantageously, the recess of the drive shaft constitutes an annular groove extending in the peripheral direction of the drive shaft. This allows that at least one holding arm can be introduced into the recess independently of the current rotational position of the drive shaft and can be moved out of the recess when necessary.

[0010] In a preferred embodiment of the present invention, the rotating body has an operating section that can be grasped by a user, wherein at least one retaining arm is coupled to the operating section and carries a latching element at its end facing away from the operating section. This facilitates the structural design of the rotating body.

[0011] Advantageously, at least one holding arm is rigidly, in particular integrally, connected to the actuating section and is flexibly elastically deformable. The flexibly elastic deformability allows the latching element of the holding arm to be moved back and forth between a latching position and a release position in a structurally simple manner.

[0012] In a preferred design solution of the present invention, the operating section constitutes a rotating knob that can be grasped by the user, which facilitates the user to rotate the rotating body relative to the guide body around the rotation axis of the drive shaft.

[0013] The latching element of at least one holding arm is preferably designed to a hook shape. This facilitates the holding arm being sunken into the recess of the drive shaft.

[0014] It is particularly advantageous if the rotating body has at least two holding arms that are diametrically opposed to one another with respect to the rotation axis of the drive shaft. The two holding arms can be sunk on opposite sides into recesses in the drive shaft, thereby securing the fastening device axially to the drive shaft with a high mechanical load capacity.

[0015] It is particularly advantageous if the two holding arms execute an expansion movement by a rotational movement of the rotating body relative to the guide body, so that the holding arms can be expanded from one another with their end regions facing the drive shaft in order to accommodate the recess of the drive shaft between them.

[0016] In a particularly preferred embodiment of the present invention, the guide element of the guide body has a number of guide slots, arranged offset from the drive shaft's axis of rotation, corresponding to the number of retaining arms. Each guide slot is penetrated by a retaining arm, and the guide slots have a first guide section and a second guide section, wherein the first guide section is at a smaller distance from the drive shaft's axis of rotation than the second guide section, and wherein, upon rotation of the rotor relative to the guide body, the retaining arm passing through the respective guide slot can move back and forth between the first guide section and the second guide section. In this embodiment of the present invention, each retaining arm of the rotor is assigned a guide slot in the form of a through-hole through which the retaining arm passes. The guide slots have guide sections at different distances from the drive shaft's axis of rotation. If the rotor rotates relative to the guide body about the drive shaft's axis of rotation, the retaining arm executes a movement having a radial component with respect to the drive shaft's axis of rotation. This results in the latching element of the holding arm occupying a smaller or larger distance from the rotation axis of the drive shaft depending on the rotation direction of the rotor, so that the latching element sinks into the recess of the drive shaft or moves out of the recess depending on the rotation direction of the rotor.

[0017] In a particularly simple design of the present invention, the guide member is designed in the form of a plate, thereby forming a slotted plate having at least one guide slot in the form of a guide passage, through which the holding arm passes.

[0018] At least one guide link is advantageously designed in the form of a hook. The first guide section of the guide link can form a first end region of the guide link and transition via an arcuate middle section into a second guide section, wherein the first guide section is at a smaller distance from the axis of rotation of the drive shaft than the second guide section.

[0019] In an advantageous embodiment of the present invention, the guide body can only be rotated to a limited extent relative to the roller body about the rotation axis of the drive shaft. This ensures that the rotational movement of the rotating body relative to the guide body only results in a limited rotational movement of the guide body relative to the roller body.

[0020] In a preferred embodiment of the present invention, the roller body comprises a hollow cylindrical base body which surrounds the torque transmission element in the circumferential direction, wherein the torque transmission element is connected to the base body via a plurality of retaining ribs arranged at intervals in the circumferential direction, and wherein the guide body has a plurality of axially oriented projections on its end side facing the torque transmission element, each of which projects into a gap between two circumferentially consecutive retaining ribs. In this embodiment, the torque transmission element is connected to the base body of the roller body via a plurality of retaining ribs arranged at intervals in the circumferential direction. The base body can, for example, carry a brush structure or a cleaning surface, such as a cleaning nonwoven or cleaning fabric, on its outer side. Gaps are arranged between the circumferentially consecutive retaining ribs. The projections arranged on the end side of the guide body facing the torque transmission element each project into these gaps. This ensures that the guide body cannot be twisted unrestricted relative to the roller body about the axis of rotation of the drive shaft. The projection of the guide body can be received by the recess with play, thereby enabling a limited rotational movement of the guide body relative to the roller body, but the projection can also form a positive connection with the recess, thereby completely preventing a rotational movement of the guide body relative to the roller body.

[0021] Advantageously, the securing device can be loaded axially with a spring-elastic restoring force when inserted into the axial roller recess. This has the advantage that, as long as the securing device is not axially secured to the drive shaft, the securing device can be moved axially under the action of the spring-elastic restoring force. Thus, as long as the securing device is not secured to the drive shaft, it can move away from the torque transmission element. This is easily detectable by the user, thereby signaling to the user that the cleaning roller is not securely secured to the drive shaft. Furthermore, the use of the spring-elastic restoring force facilitates replacement of the cleaning roller.

[0022] Advantageously, the fastening device comprises a spring element which, when the fastening device is inserted into the roller recess, comes into contact with the torque transmission member and applies a spring-elastic restoring force to the guide body. For example, it can be provided that, when the fastening device is inserted into the roller recess, the spring element is compressed between the guide body and the torque transmission member.

[0023] Advantageously, mutually assigned rotation guide elements are arranged on both the guide body and the rotating body for guiding the rotating body in a rotational movement relative to the guide body. The rotational movement of the rotating body can also be limited by means of the rotation guide elements.

[0024] The rotation guide element can, for example, form at least one guide slot and a guide pin associated with the guide slot, which guide pin is inserted into the guide slot. The guide slot can extend in the peripheral direction with respect to the rotation axis of the drive shaft, for example, within an angle range of 90°.

[0025] Preferably, at least one guide slot is arranged on the guide body and the guide pin is arranged on the rotating body. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] An advantageous embodiment of a cleaning device according to the present invention is schematically illustrated in the figure and generally designated by reference numeral 10. In this embodiment, cleaning device 10 is a hand-guided floor cleaning device 12 that can be manually guided by a user along a floor surface 14 to be cleaned in order to clean the floor surface. Floor cleaning device 12 can be moved back and forth in and against a feed direction 16. However, the present invention is not limited to hand-guided floor cleaning devices, but is defined by the features of claim 1.

[0036] The cleaning device 10 has a cleaning head 18 with a housing 20, the housing 20 having a front side 22, a rear side facing away from the front side 22, a first longitudinal side 26, a second longitudinal side 28 facing away from the first longitudinal side 26, and an upper side 29. The upper side 29 is defined by a top wall 27 of the housing 20. Figure 3 is hidden.

[0037] A rod 30 is held on the housing 20 so as to be pivotable about a pivot axis 34 by means of a joint 32 .

[0038] An operating unit 36 ​​is located at the end of the rod 30 facing away from the cleaning head 18. The operating unit 36 ​​has a pistol-like handle 38 that can be grasped by the user with one hand. A coupling element 40 is located on the operating unit 36 ​​and is connected to two nozzles arranged on the front side 22 of the housing 20 via a fluid line (not shown). The fluid line runs through the rod 30. A water hose (not shown in the figure for a better overview) can be connected to the coupling element 40. Water can be supplied to the cleaning device via the water hose from a water supply network or a pump, and this water can be applied to the floor 14 to be cleaned via nozzles 42 and 44.

[0039] In addition to the handle 38 , the operating element 36 also has a power plug 46 , which can be connected to a power supply cable for supplying power to the cleaning device 10 and is connected to the cleaning head 18 via a cable 48 which is largely guided through the rod 30 .

[0040] The housing 20 of the cleaning head 18 accommodates a drive device 50, which in the illustrated embodiment is configured as an electric motor that is electrically connected to a power plug 46 via a cable 48 for supplying electrical energy. To switch the drive device 50 on or off, an electric switch having a switch lever 52 is arranged on the handle 38 of the operating unit 36, which can be actuated by the user.

[0041] The housing 20 covers a front cleaning roller unit 54 arranged adjacent to the front side 22 and a rear cleaning roller unit 56 arranged adjacent to the rear side 24. The two cleaning roller units 54, 56 are designed to be identical. In the embodiment shown, the two cleaning roller units 54, 56 constitute brush roller units respectively.

[0042] The two cleaning roller units 54, 56 each have two cleaning rollers 58, 60 arranged aligned with one another, which are connected in a rotationally fixed and detachable manner to a drive shaft 62. The drive shaft 62 is coupled to the drive device 50 via a transmission element 64 and can be rotated by the drive device about an axis of rotation 66.

[0043] Cleaning rollers 58, 60 are constructed to be identical. Therefore, only cleaning roller 58 is described in detail below. Corresponding statements also apply to cleaning roller 60 in the same manner.

[0044] The cleaning roller 58 has a roller body 68, which comprises a hollow cylindrical base body 70 and a torque transmission element 72 which is surrounded in the circumferential direction by the base body 70. In the region upstream of the torque transmission element 72, the base body 70 is formed with an axial roller recess 74 which extends from the torque transmission element 72 to an end face 76 of the roller body 68 facing away from the torque transmission element 72.

[0045] The torque transmission member 72 is integrally connected to the base body 70 via a plurality of radially oriented retaining ribs 78, which are arranged evenly distributed around the circumference of the torque transmission member 72. Between adjacent retaining ribs 78, a gap 80 extends, which is delimited in the radial direction on the one hand by the torque transmission member 72 and on the other hand by the base body 70.

[0046] The torque transmission member 72 is designed as a hollow body and is passed through by the drive shaft 62. The drive shaft and the torque transmission member 72 form a positive lock and have flat portions 82 on the sides facing away from each other. This allows the torque to be transmitted from the drive shaft 62 to the roller body 68.

[0047] The drive shaft 62 projects out of the torque transmission member 72 in the direction of the end face 76 and, in its projecting region, has a recess 84 in the form of an annular groove 86 extending over the circumference of the drive shaft 62 .

[0048] The cleaning roller 58 can be placed onto the drive shaft 62 in a rotationally fixed manner in the axial direction about the rotation axis 66 and can be axially fixed on the drive shaft 62 by means of a fixing device 88 .

[0049] Especially from Figures 4 to 8 It can be seen that the fixing device 88 comprises a guide body 90 and a rotational body 92 which is held in the guide body 90 so as to be rotatable about the axis of rotation 66 and axially fixed.

[0050] The guide body 90 has a guide sleeve 94 which, at its end facing away from the torque transmission element 72, carries an annular collar 96 extending from the roller recess 74 and forming a stop element 98 which can abut in the axial direction against the end face 76 of the roller body 68. For this purpose, the end face 76 forms a stop surface 100 associated with the stop element 98.

[0051] A plate-shaped guide member 102 is arranged in the guide sleeve 94 at a distance from the annular collar 96 , said guide member forming a gate plate and being arranged perpendicular to the axis of rotation 66 of the drive shaft 62 .

[0052] Especially from Figure 7 It can be seen that the guide member 102 has two guide links 104, 106, which are arranged offset to the axis of rotation 66 and are essentially hook-shaped and diametrically opposed to each other. The guide links 104, 106 each have a first guide section 108 or 110, which transitions via an arcuate middle section 112 or 114 into a second guide section 116, 118, wherein the first guide sections 108, 110 are at a smaller distance from the axis of rotation 66 than the second guide sections 116, 118.

[0053] The guide sleeve 94 has, on its end face 120 facing the torque transmission member 72, a plurality of projections 122 arranged at regular intervals in the circumferential direction and extending in the axial direction. On the side of the guide member 102 facing away from the projections 122, the guide sleeve 94 has guide slots 124, 126 lying opposite one another and extending in the circumferential direction over an angular range of approximately 90°.

[0054] The guide sleeve 94 surrounds the rotating body 92, which is held therein so that it can rotate about the axis of rotation 66 and cannot move axially. The rotating body 92 has an operating section 128, which forms a rotary knob 130 that can be grasped by a user to rotate the rotating body 92. Two diametrically opposed retaining arms 132, 134 are connected to the rotary knob 130, are integrally connected to the rotary knob 130, and are designed to be flexibly elastic. The retaining arms 132, 134 extend through the guide slots 104 and 106, respectively, and have hook-shaped latching elements 136 and 138 at their ends facing away from the rotary knob 130.

[0055] In order to guide the rotating body 92 in the rotational direction, the rotating body 92 has two guide pins 140 , 142 diametrically opposed to one another and pointing radially outward, which respectively engage in a guide slot 124 , 126 .

[0056] The fastening device 88 can be inserted into the roller recess 74, wherein the annular collar 96 comes into contact with the stop surface 100 of the end face 76 of the roller body 68. When inserted into the roller recess 74, the projections arranged on the end face 120 of the guide sleeve 94 respectively sink into one of the recesses 80. This ensures that the fastening device 88 can only be twisted in the circumferential direction to a limited extent at most.

[0057] By rotating the rotating body 92 about the rotation axis 66 of the drive shaft 62, the holding arms 132, 134 can be moved back and forth between a locked position and a released position under the action of the guide links 104, 106. In the locked position, the holding arms 132, 134 each adopt a position in the first guide section 108 or 110 of the respective guide link 104, 106, so that the respective latching element 136, 138 is embedded in the annular groove 86 of the drive shaft 62, thereby securing the fixing device 88 together with the cleaning roller 58 in the axial direction on the drive shaft 62. By rotating the rotating body 92 by 90° about the rotation axis 66, the holding arms 132, 134 are moved into the respective second guide section 116, 118 of the guide links 104, 106. This results in the flexibly elastically deformable holding arms 132, 134 being stretched apart from one another due to the greater distance between the second guide sections 116, 118 and the axis of rotation 66, so that the latching elements 136, 138 are spaced apart from the annular groove 86. This is particularly true in Figure 5 This allows the fixing device 88 to be removed from the drive shaft 62 together with the cleaning roller 58 .

[0058] On the side of the guide member 102 facing away from the guide slots 124 , 126 , the guide sleeve 94 surrounds a spring element 144 . In the illustrated embodiment, this spring element is designed as a coil spring and is compressed between the guide member 102 and the torque transmission member 72 when the securing device 88 is inserted into the roller recess 74 . Consequently, the securing device 88 is inserted into the roller recess 74 against the spring-elastic restoring force exerted by the spring element 144 . If the user releases the rotor 92 after inserting the securing device 88 into the roller recess 74 , the securing device 88 is displaced against the insertion direction under the action of the spring elasticity of the spring element 144 , provided that the retaining arms 132 , 134 occupy their released position rather than their locked position. This movement of the securing device 88 against the insertion direction signals to the user that the cleaning roller 58 is not axially secured to the drive shaft 62 .

[0059] The cleaning device 10 is characterized by easy handling when replacing the cleaning rollers 58, 60. Therefore, to replace the cleaning rollers 58, 60, the rotating body 92 only needs to be rotated relative to the guide body 90 about the rotation axis 66 until the retaining arms 132, 134 adopt their released position, so that the cleaning rollers 58, 60 can then be separated from the drive shaft 62. If the cleaning rollers 58, 60 are to be mounted on the drive shaft 62, the cleaning rollers 58, 60 can be pushed onto the drive shaft 62 in the axial direction, and to axially secure the cleaning rollers 58, 60, the user only needs to rotate the rotating body 92 relative to the guide body 90 until the latching elements 136, 138 of the retaining arms 132, 134 adopt their latching position again, in which they engage in the annular groove 86 of the drive shaft 62.
