[0001] The present invention relates to a surface cleaning apparatus comprising: a cleaning head; at least one cleaning roller rotatable about a rotation axis; a drive motor for the at least one cleaning roller; and a holding device on which the at least one cleaning roller is rotatably supported, and which holds the at least one cleaning roller on the cleaning head.

[0002] The present invention also relates to a method for operating a surface cleaning device, the surface cleaning device comprising: a cleaning head; at least one cleaning roller rotatable about a rotation axis; a drive motor for the at least one cleaning roller; and a holding device for the at least one cleaning roller. Background Technology

[0003] WO 2023 / 152082 A1 discloses a surface cleaning apparatus comprising: a cleaning head; at least one cleaning roller; and a drive motor for the at least one cleaning roller, having at least one drive shaft, wherein the drive motor and the at least one drive shaft are arranged on the cleaning head, and wherein the at least one drive shaft rotates about a rotation axis during operation of the surface cleaning apparatus. At least one housing is removably positioned on the cleaning head using a retaining device for the at least one cleaning roller. The retaining device has at least two spaced-apart retaining portions for the at least one cleaning roller, through which the at least one cleaning roller is removably held on the at least one housing when the at least one housing is removed from the cleaning head, and wherein, when the at least one housing is arranged on the cleaning head, the at least one cleaning roller is torque-coupled to the at least one drive shaft. Summary of the Invention

[0004] The objective of this invention is to provide a surface cleaning apparatus of the type described at the beginning, wherein at least one cleaning roller can be easily inserted or removed.

[0005] In the surface cleaning device of the type described at the beginning, this task is solved according to the invention by the following means: the holding device has at least one swingable flap, which is equipped with a spring device, wherein at least one cleaning roller is held on the holding device in a clamping manner by the at least one flap, and a scraping device for scraping off dirty fluid from the at least one cleaning roller is mounted on the at least one flap.

[0006] At least one flap (when at least one flap is closed) allows at least one cleaning roller to be held on at least one housing by a form lock and a clamping force applied by at least one flap on the holding device. The rotatability of at least one cleaning roller about a rotation axis is ensured.

[0007] By opening the flap (against the force of the spring mechanism), at least one cleaning roller can be easily removed.

[0008] Therefore, roller replacement can be performed in a simple manner on the holding device.

[0009] At least one flap has the function of removing or placing at least one cleaning roller from or onto the holding device before and after operation of the surface cleaning equipment. During operation of the surface cleaning equipment, at least one flap holds at least one cleaning roller on the holding device, which in turn holds it on the cleaning head.

[0010] By integrating at least one scraping device into at least one flap, dirty fluid can be effectively removed from at least one cleaning roller even during operation of the surface cleaning equipment. Since at least one flap is spring-loaded, the scraping device is also spring-loaded and pressed against the lining of at least one cleaning roller, and particularly into the lining of at least one cleaning roller. This results in effective dirt removal.

[0011] The spring-loaded scraping device also allows for manufacturing tolerances and compensation for wear on at least one cleaning roller. Optimized cleaning performance is achieved using at least one cleaning roller throughout its entire service life, even as its diameter decreases due to wear.

[0012] Advantageously, at least one of the following is provided: - The clamping force applied to at least one cleaning roller by at least one flap is oriented transversely and, in particular, perpendicularly to the axis of rotation of at least one cleaning roller; - The clamping force applied by at least one flap to at least one cleaning roller acts in the direction of a portion of the circumferential wall of the holding device.

[0013] At least one flap provides a circumferentially form-locking fixation of at least one cleaning roller to the holding device. The flap applies an additional clamping force, which in turn ensures optimized positioning of the scraping device on at least one cleaning roller. By releasing the clamping force, the flap can be opened from the cleaning head and the holding device, and at least one cleaning roller can be easily removed from the holding device.

[0014] When the clamping force acts in the direction of the cleaning head's placement plane relative to the surface to be cleaned, a design structure that is advantageous for the cleaning head is achieved.

[0015] Furthermore, it is advantageous that the swing axis of at least one flap's swing bearing assembly is oriented parallel to the rotation axis of at least one cleaning roller, or at an acute angle of up to 30° to it. This results in a space-saving structure. Optimal retention of at least one cleaning roller is achieved in the retaining device.

[0016] Advantageously, at least one of the following is provided: - The cleaning head is equipped with a placement plane for the surface to be cleaned, wherein the rotation axis of at least one cleaning roller is oriented parallel to the placement plane; - The axis of rotation of at least one cleaning roller is oriented transversely to, and in particular perpendicular to, the direction of travel of the cleaning head.

[0017] This allows for effective surface cleaning, especially using cleaning robots.

[0018] In one embodiment, the retaining device has a circumferential wall for at least one cleaning roller, which covers a portion of the periphery of the at least one cleaning roller. This provides a contaminant wall. The circumferential wall itself can retain components of the cleaning head's design, such as interfaces for nozzle devices and wetting devices for supplying cleaning fluid to the at least one cleaning roller. By covering a portion of the area, optimized retention of the at least one cleaning roller on the retaining device can be achieved.

[0019] Furthermore, it is advantageous to have at least one of the following features: - The circumferential wall has a first region, on which a second region is disposed, wherein the second region is formed by at least one flap; - The circumferential walls are constructed to be closed and / or continuous; - The circumferential wall has a first circumferential extension when at least one flap is opened, wherein the first circumferential extension has an angular range of less than 180° and especially less than 150°, and wherein, in particular, the first circumferential extension is formed by a first region of the circumferential wall; - The circumferential wall has a second circumferential extension when at least one flap is closed, wherein at least one closed flap applies a clamping force to at least one cleaning roller, and the second circumferential extension has an angular range greater than 180°, wherein the second circumferential extension is formed, in particular, by a first region and a second region of the circumferential wall together.

[0020] The circumferential wall has a first region and a second region, wherein the second region is formed by at least one flap. When at least one flap is closed, an "integral" circumferential wall consisting of the first region and the second region is formed for holding at least one cleaning roller.

[0021] When the circumferential wall is constructed to be closed or continuous, it allows for the optimal positioning of structural components. Additionally, a fouling protector wall is also provided.

[0022] When the circumferential wall has a first circumferential extension covering an angle range of less than 180° when the flap is open, at least one cleaning roller can be easily inserted into the retaining device. When the circumferential wall has a second circumferential extension greater than 180° when at least one flap is closed, the cleaning roller, which is circular in cross-section, is clamped by the circumferential wall and obtained form-locking fixation. This form-locking fixation is also supported by the clamping force of at least one flap. Thus, reliable retention on the retaining device is achieved, wherein the cleaning roller can be easily inserted or removed when at least one flap is open.

[0023] Specifically, the cleaning head is equipped with a placement plane for the surface to be cleaned, and this placement plane is equipped with a height axis oriented perpendicular to the placement plane. The holding device has an upper region where the distance between the holding device and the placement plane along the height axis is maximized, and a swing bearing device for at least one flip cover is positioned in the upper region away from the placement plane. This achieves optimal installation of the swing bearing device on the cleaning head. The swing bearing device can be arranged in a space-saving manner. Furthermore, the "circumferential constraint" of at least one cleaning roller on the holding device can be easily achieved via at least one flip cover.

[0024] Furthermore, it is advantageous that a first circumferential extension of the circumferential wall of the retaining device extends from the underside of the circumferential wall toward the placement plane to the oscillating bearing device. This first circumferential extension is present when the flap is open, and at least one cleaning roller can be easily placed onto or removed from the circumferential wall.

[0025] When the second circumferential extension of the circumferential wall of the retaining device extends from the oscillating bearing device to the end side of at least one flap, wherein, when at least one flap is closed, the at least one closed flap applies a clamping force to at least one cleaning roller, the end side of which faces the placement plane, the “circumferential constraint” of at least one cleaning roller on the retaining device can be achieved in a simple manner.

[0026] When the swing axis of the swing bearing device is located above the rotation axis and the swing axis and rotation axis intersect with the same height axis or are offset by up to 3 cm in the lateral direction, the spatially optimized arrangement of the swing bearing device is obtained.

[0027] In one embodiment, exactly one flip cover is provided, which is particularly associated with a sway bearing device having a plurality of sway bearings spaced apart from each other. Thus, while keeping the device design simple, reliable opening and closing of at least one flip cover can be achieved, enabling a low-maintenance implementation.

[0028] More advantageously, at least one flap is provided with a port for guiding away the scraped dirty fluid and coupling it into a tank device for the dirty fluid. This allows the scraped dirty fluid to be coupled into the tank device via the flap with a minimized transport path.

[0029] In one embodiment, at least one flap has a first end face and an opposing second end face, and the scraping device has at least one scraper that can penetrate into the lining of at least one cleaning roller, and the scraper is positioned on at least one flap between the first end face and the second end face, and in particular spaced apart from both the first and second end face. Thus, on the one hand, an optimized “circumferential constraint” function of at least one flap is achieved, and on the other hand, optimized positioning of at least one scraper for scraping dirty fluid from at least one cleaning roller is obtained.

[0030] Advantageously, a port for guiding dirty fluid from at least one cleaning roller is positioned on at least one scraper blade. Specifically, the port and the at least one scraper blade share a common edge. This allows for efficient guidance of the dirty fluid and its coupling into a tank device for the dirty fluid.

[0031] For the same reason, it is advantageous that the port device is positioned between the first end and the second end, and in particular spaced apart from both the first and second end.

[0032] In one advantageous embodiment of the design, at least one guiding element for guiding and securing the device on the cleaning head is arranged on the outer side of the circumferential wall of the retaining device, opposite to at least one cleaning roller. The circumferential wall thus serves to retain the elements in the design structure itself.

[0033] This results in a compact structure and reduces the number of components required.

[0034] In one embodiment, at least one cleaning roller is positioned between at least one guide element and a tank device for dirty fluid. This results in a space-saving and compact structure.

[0035] Advantageously, with reference to the circumferential direction of at least one cleaning roller, the at least one guide element is positioned within an angular range of 70° to 110°, and especially 90°, with respect to the oscillating bearing device for at least one flap. This results in a space-saving arrangement.

[0036] More advantageously, the retaining device is a housing or part of a housing, which is positioned on the cleaning head in a removable manner, and in particular, can be removed from the receiving portion of the cleaning head in a removal direction at least approximately parallel to the rotation axis of at least one cleaning roller, and can be inserted into the receiving portion of the cleaning head in the opposite direction of the removal direction. This allows for simple roller replacement on the cleaning head.

[0037] In one embodiment, a rotating bearing for at least one cleaning roller is positioned on the holding device. This provides a rotatable support for at least one cleaning roller on the holding device.

[0038] In one embodiment, an edge flange is arranged on the end side of the retaining device, providing an axial stop surface for at least one cleaning roller. This provides axial fixation of at least one cleaning roller on the retaining device, particularly opposite to the rotating bearing. At the respective ends of the retaining device, the edge flange on the end side prevents at least one cleaning roller from "falling off." Structural elements, such as lugs for securing devices, may also be arranged on the edge flange. The edge flange may be positioned on at least one flap or on the circumferential wall of the retaining device.

[0039] Of particular advantage is that the edge flange is mounted on the retaining device away from the rotary bearing. The rotary bearing itself provides an axial stop surface. Thus, the edge flange also provides an axial stop surface in the opposite direction.

[0040] Furthermore, it is advantageous that an interface for a wetting device for the cleaning fluid is arranged on or in the region of the edge flange on the retaining device. Thus, especially when the retaining device is positioned on the cleaning head, automatic fluid connection with the wetting device on the rest of the cleaning head can be achieved.

[0041] Furthermore, it is advantageous that a portion of the edge flange is provided for securing the retaining device within the receiving portion of the cleaning head with respect to the insertion and removal directions, and in particular, at least one nose is provided with the securing device. This results in a structurally simple design. The press-type snap-fit ​​device can be implemented in a simple manner.

[0042] In one embodiment, a drive motor for at least one cleaning roller is positioned in the housing of the holding device. During operation of the surface cleaning equipment, the at least one cleaning roller held on the holding device is fitted onto the drive motor. This achieves optimized space utilization. The space already present in the housing is also used for positioning the drive motor.

[0043] In one embodiment, a cartridge holder for at least one cartridge with a holding device is positioned on the cleaning head body, wherein the at least one cartridge is detachably mounted in the cartridge holder, and wherein a guiding device is provided, via which the at least one cartridge is guided on the cartridge holder in a direction parallel to the insertion direction and held transversely to the insertion direction. This provides simple and defined guidance of the at least one cartridge on the cleaning head. Axial fixation can also be easily achieved when inserting the at least one cartridge. Furthermore, removal can also be performed in a simple manner.

[0044] Advantageously, at least one of the following is provided: - At least one cleaning roller has a textile lining, and in particular a microfiber lining; - At least one cleaning roller is configured as a wet wiping roller; - At least one cleaning roller is configured as a cleaning roller for hard surfaces.

[0045] In principle, it is also possible that at least one cleaning roller has a bristle liner and, for example, only bristle bundles, or that there are bristle bundles and a textile area.

[0046] In principle, the surface cleaning device according to the invention can be implemented, for example, as a hand-guided surface cleaning device, which in particular has a lever mechanism. Specifically, an operator standing behind the cleaning head guides the surface cleaning device with the cleaning head onto the surface in a standing position. In one embodiment, a self-propelled and self-steering configuration is provided, and in particular, a configuration as a suction robot, a wiping robot, or a suction-wiping robot.

[0047] Advantageously, at least one of the following is provided: - At least one cleaning roller is equipped with a tank device for dirty fluid, which is particularly mounted on the cleaning head in a removable manner; - Dirty fluid is conveyed to the tank device from at least one cleaning roller without a blower or via a blower device; - A wetting device is provided, which applies cleaning fluid to at least one cleaning roller and / or the surface to be cleaned; - At least one cleaning roller is equipped with a scraping device for scraping dirty fluid from at least one cleaning roller.

[0048] A tank device for dirty fluids can contain the mixture of dirt and filth.

[0049] Dirt can be better dissolved on hard surfaces by wetting the surface to be cleaned, especially via at least one cleaning roller.

[0050] The scraping device can effectively scrape away and guide the dirty fluid from at least one cleaning roller.

[0051] Furthermore, it is advantageous to have at least one of the following features: - In addition to at least one cleaning roller, at least one rotatable brush roller is provided on the cleaning head, and at least one brush roller is equipped with a fan device for generating a suction flow. - At least one brush roller is equipped with a sludge collection container, which is removably mounted on the cleaning head.

[0052] The suction operation of the surface cleaning equipment can be achieved by using at least one rotatable brush roller and its associated fan device, so that, for example, textile surfaces can also be cleaned.

[0053] According to the invention, a method of the type described at the beginning is also provided, wherein at least one spring-loaded flap is mounted on a holding device, at least one cleaning roller is held on the holding device in a clamping manner via the at least one flap, and wherein a scraping device is mounted on the at least one flap, the scraping device being positioned on the at least one cleaning roller via the at least one flap.

[0054] The method according to the invention has the advantages described in conjunction with the surface cleaning apparatus according to the invention.

[0055] In particular, the method according to the invention can be performed on the surface cleaning device according to the invention, or the surface cleaning device according to the invention can be operated using the method according to the invention. Attached Figure Description

Detailed Implementation

[0057] One embodiment of surface cleaning equipment is a floor cleaning device, which is a self-propelled and self-steering floor cleaning device. Figures 1 to 9 This surface cleaning equipment, especially the suction-wiping robot, is suitable for cleaning textile floors and hard floors.

[0058] The surface cleaning device 10 includes a cleaning head 12 having a self-propelled and self-steering cleaning head body 14 (walking body).

[0059] A (ground) station may be set up, which is particularly used for charging the battery device and, if necessary, for cleaning the cleaning head 12 (not shown in the figure).

[0060] During cleaning operations, the surface cleaning device 10 places its cleaning head 12 on a surface 16 to be cleaned, such as a floor (see, for example, [reference needed]). Figure 10 )superior.

[0061] A travel drive 18 is arranged on the cleaning head body 14. This travel drive is paired with wheels 20 ( Figure 2 The drive mechanism is as follows: In one embodiment, a first wheel 20a and a second wheel 20b are provided, which share a common wheel axis 22. The wheels 20 are driven by a drive driver 18 to rotate about the wheel axis 22.

[0062] Support rollers 24, spaced apart from the wheels 20, are also arranged on the cleaning head body 14. Each support roller 24 has a rotation axis. This support roller can oscillate about a steering axis perpendicular to this rotation axis. In principle, it is possible for the support roller 24 to be a passive steering roller, which is not driven (especially when rotating about the corresponding rotation axis and when oscillating about the steering axis). Changes in direction of the cleaning head 12 are achieved by corresponding manipulation of the wheels 20a and 20b by a control device positioned on the cleaning head body 14. Changes in direction are achieved, in particular, by the rotation of the wheels 20a and 20b at different speeds.

[0063] In an alternative embodiment, the support roller 24 is configured as an active steering roller for controlling the direction of the cleaning head 14. Accordingly, this control is performed via a control device.

[0064] The surface cleaning device 10 has a main travel direction 26. This main travel direction 26 is the forward direction. When the cleaning head 12 travels along the main travel direction 26, the rotation axis of the support roller 24 is oriented parallel to the wheel axis 22.

[0065] The cleaning head 12 is equipped with a placement surface 28 (see, for example, see...) Figure 10 The placement plane 28 is pre-defined by the wheel 20 and the support roller 24. When the surface 16 is flat, the cleaning head 12 rests against the surface when it is placed on the surface 16 via the placement plane 28.

[0066] The surface cleaning device 10 includes at least one brush roller 30 for suction operation. The surface cleaning device also includes an additional cleaning roller 32, by means of which wet wiping cleaning can be performed.

[0067] During the cleaning operation of the surface cleaning device 10, the brush roller 30 and / or the cleaning roller 32 rest against the placement plane 28 and act on the surface 16 to be cleaned. (In principle, it is possible that during the cleaning operation, both the brush roller 30 and the cleaning roller 32 act on the surface 16 to be cleaned, or only the brush roller 30 acts on the surface 16 to be cleaned. In another embodiment, it may also be configured that only the cleaning roller 32 acts on the surface 16 to be cleaned.)

[0068] A navigation device 34 is arranged on the cleaning head body 14. The navigation device 34 is a sensor device and includes at least one sensor element. The navigation device 34 is signal-operatedly connected to a control device for controlling the movement of the surface cleaning equipment 10. The navigation device 34 includes, for example, one or more optical sensors, one or more radar sensors, one or more infrared sensors, and / or one or more ultrasonic sensors.

[0069] The cleaning head body 14 has a front end 36 and a rear end 38 relative to the main travel direction 26 (forward direction). The cleaning head 12 is equipped with a longitudinal axis 40, which extends between the front end 36 and the rear end 38 and is parallel to the main travel direction 26.

[0070] In the region of the rear end 38, a tank device 42 for dirty fluid and a tank device 44 for cleaning fluid are specifically positioned (see, for example, see...). Figure 24 ).

[0071] In one embodiment, the canister device 42 and canister device 44 are combined in a combined manner and can be removed from or inserted into the cleaning head 12 as a combination.

[0072] Dirty fluid is understood here as a fluid that is, in principle, capable of flowing. It can consist of dirt particles or a mixture of dirt particles and liquid (especially water, and if necessary, surfactant additives).

[0073] The cleaning head body 14 has a lower side 46 facing the placement plane 28. The cleaning head body has an upper side 48 opposite to the lower side 46. The wheel 20 and the support roller 24 are arranged on the lower side 46. The navigation device 34 is positioned on the upper side 48 at least in a partial area.

[0074] On the cleaning head body 14, a bumper 50 is arranged in the area of ​​the front end 36, through which the collision between the surface cleaning device 10 and an obstacle can be detected tactilely. The bumper 50 is one or more tactile sensor elements or includes one or more tactile sensor elements, which are connected to the control device in a signal-acting manner.

[0075] A cliff sensor 52 is arranged at position 46 on the lower side of the cleaning head body 14 (see...). Figure 2 These cliff sensors 52 are connected to the control unit in a signal-based manner. These cliff sensors 52 are used to prevent surface cleaning equipment 10 from falling, for example, in stairwell areas, by correspondingly identifying a "cliff".

[0076] The cleaning head body 14 includes a rear region 54. Tank devices 42 and 44 and a cleaning roller 32 are positioned in the rear region 54. A rear end portion 38 is located in the rear region 54. The cleaning head body 14 also includes a front region 56 connected to the rear region 54. A front end portion 36 is located in the front region 56.

[0077] In the front area 56, adjacent to the rear area 54, there is a sludge collection container (in... Figure 3 The receiving section 58 (not shown in the image) contains a sludge collection container, which is specifically used to collect dry dirt and is associated with the brush roller 30.

[0078] An interface 60 is provided at the receiving section 58, through which the corresponding sludge collection container is connected to the blower unit 62. The blower unit 62 is located at the front region 56. The blower unit generates a suction flow. This suction flow is applied to the receiving region 64, where the brush roller 30 is positioned (see...). Figure 2 The brush roller 30 is rotatably supported about a rotation axis 66. A drive motor 68 is arranged in the front region 56, which drives the brush roller 30 to rotate about the rotation axis 66 during cleaning operation.

[0079] The blower device applies a suction flow to the receiving area 64, and in particular, draws in dry dirt and holds it in the sludge collection container (not shown) in the receiving section 58.

[0080] The sludge collection container can be removed from the receiving section 58 for emptying and cleaning.

[0081] In one embodiment, the receiving portion 64 is positioned on the cleaning head body 14 (referring to longitudinal axis 40) between the receiving area 64 having the brush roller 30 and the can assembly 42 or 44. The receiving portion 58 is positioned on the cleaning head body 14 between the cleaning roller 32 and the brush roller 30.

[0082] Along the longitudinal axis 40, following the receiving area 64 with the brush roller 30, a rechargeable battery device 70 is placed in the front area 56 of the cleaning head body 14.

[0083] In the illustrated embodiment, the receiving area 64 with brush roller 30 is positioned between the battery device 70 and the receiving portion 58 for the sludge collection container with reference to the longitudinal axis 40.

[0084] In the region of the front end 36, a contact element 72 is arranged at the lower side 56 of the cleaning head body 14 (see...). Figure 2 These contact elements, in cooperation with the site (ground station), enable the charging of the battery device 70.

[0085] The rotation axis 66 of the brush roller 30 is oriented transversely to and, in particular, perpendicular to the longitudinal axis 40.

[0086] The axis of rotation 66 is oriented parallel to the placement plane 28.

[0087] In particular, the receiving area 64 with brush roller 30 is positioned between the first roller 20a and the second roller 20b (see...). Figure 2 ).

[0088] Side brooms 74a and 74b are also installed at the front end 56 of the cleaning head 12. These side brooms extend beyond the periphery of the cleaning head body 14.

[0089] In one embodiment, a first side broom 74a and a second side broom 74b are provided. Each of the side brooms 74a and 74b is equipped with a drive motor 76 in the front region 56 of the cleaning head body 14. The side brooms 74a and 74b are rotatable about rotation axes that are transverse to and, in particular, perpendicular to the placement plane 28, or form a small acute angle with the placement plane 28, particularly an acute angle less than 10°.

[0090] In one embodiment, the battery device 70 is positioned between the drive motors 76 for the side brooms 74a, 74b, and in particular, the battery device 70 and the drive motors 76 are on a straight line (see [link]). Figure 3 The line 78 is perpendicular to the longitudinal axis 40 and oriented. It is also parallel to the axis of rotation 66.

[0091] In one embodiment, the blower assembly 62 is located on one side of the cleaning head body 14, while the drive motor 68, for example, for the brush roller 30, is located on the other side. In particular, the central plane of the cleaning head body 14 is located between the blower assembly 62 and the drive motor 68, the longitudinal axis 40 is located in this central plane, and this central plane is perpendicular to the placement plane 28.

[0092] In one embodiment, a blower 62 is located on one side of the housing 58, wherein a fluid connection with the sludge collection container is established via the blower 62 through the corresponding side of the housing 58, while a drive motor 68 is located on the opposite side of the housing 58.

[0093] On the cleaning head body 14, at the upper side 48, there is an openable and, in particular, flip-up cover 78 (see...). Figure 1 According to Figure 3 The cover is not shown in the partial view. Cover 78 covers the tank devices 42 and 44 at the upper side 48. Furthermore, the cover also covers the receiving portion 58 for the sludge collection container. The cover 78 must be opened in order to remove the sludge collection container from the receiving portion 58.

[0094] The cleaning head body 14 has a first lateral side 80 and an opposite second lateral side 82. The first lateral side 80 and the second lateral side 82 are particularly mirror-symmetrical with respect to the intermediate plane where the longitudinal axis 40 is located.

[0095] The first lateral side 80 and the second lateral side 82 can be flat or arched.

[0096] On the cleaning head body 14, a receiving portion 84 for the cleaning roller 32 is arranged between the first lateral side 80 and the second lateral side 82. The receiving portion 84 is in particular a receiving groove. The receiving portion 84 faces downward 46 and is therefore open to the placement plane 28, so that the cleaning roller 32 positioned in the receiving portion 84 can act on the surface 16 to be cleaned.

[0097] The receiving portion 84 is located in the rear region 54 of the cleaning head body 14. The receiving portion is spaced apart from the rear end portion 38 of the cleaning head body 14.

[0098] The receiving portion 84 is closed at the first lateral side 80 by a transverse wall 86. The transverse wall 86 is specifically fixedly arranged on the cleaning head body 14, or is a fixed component of the cleaning head body 14.

[0099] At the second lateral side 82, the receiving portion 84 is opened via an opening 88. A cover 90 is provided for the opening 88, by means of which the opening 88 at the second lateral side 82 can be closed.

[0100] Figure 4 The image shows a portion of the cleaning head 12, with the cover 90 closed. Figure 5 and Figure 6 In order to remove the cleaning roller 32 or place it into the receiving part 84, the cover 90 is opened.

[0101] To position the cleaning roller 32 within the receiving portion 84, a housing 92 is provided (see [reference]). Figures 7 to 24 The housing 92 includes a retaining device 94 for the cleaning roller 32. When the housing 92 is positioned as intended in the receiving portion 84 of the cleaning head 12, the cleaning roller 32 is driven at the retaining device 94, thereby enabling it to rotate about the rotation axis 96.

[0102] The axis of rotation 96 is parallel to the placement plane 28. This axis of rotation is transverse to, and in particular perpendicular to, the main travel direction 26 (forward direction 26). This axis of rotation is transverse to, and in particular perpendicular to, the longitudinal axis 40. This axis of rotation is at least approximately parallel to the axis of rotation 66 of the brush roller 30.

[0103] On the cleaning head body 14, a cartridge retainer 98 is positioned in the receiving portion 84 to retain the cartridge 92, and thus indirectly to retain the cleaning roller 32 in the receiving portion 84. The cartridge retainer 98 (see especially...) Figure 16and Figures 20 to 24 The cleaning head 12 is a non-removable component. It may be fixedly positioned on the cleaning head 12 (on the cleaning head body 14), or, in an embodiment further described below, positioned on the cleaning head body 14 in a movable and, in particular, swingable manner.

[0104] A guide device 100 is provided for guiding the case 92 on the case holder 98 and holding it in a position in the receiving section 84.

[0105] The guide device 100 includes a first portion 102, which is arranged or formed on the housing retainer 98 (see, for example, see...). Figure 22 and Figure 23 The guiding device also includes a second part 104, which is arranged or formed on the housing 92. The first part 102 and the second part 104 cooperate with each other.

[0106] The retaining device 94 (cassette 92) has a circumferential wall 106. The circumferential wall 106 extends along the axial direction 108 between a first end 110 and an opposite second end 112. When the cassette 92 is positioned in the receiving portion 84 as intended, the axis of rotation 96 is parallel to the axis of rotation 96 of the cleaning roller 32.

[0107] Axis 108 is the axial axis. The cleaning roller 32 has a cylindrical external shape, with its axial axis parallel to the rotation axis 96. Therefore, the housing 92 can be fitted with a circumferential direction 114 (see...). Figure 12 ) and radial direction 116. According to Figure 12 In the illustration, the axial axis 108 is perpendicular to the plane of the drawing. The circumferential direction 114, the radial direction 116, and the axial axis 108 define the polar coordinates.

[0108] The circumferential wall 106 has a first region 118 and a second region 120.

[0109] The second region 120 is arranged on the first region 118 in a movable manner.

[0110] The first region 118 extends circumferentially 114 from the lower side 122 of the circumferential wall 106 toward the placement plane 28 to the end region 124. Here, when the housing 92 is installed on the cleaning head 12 as specified, the end region 124 is located at the upper region 126 of the housing 92 (see [reference]). Figure 12 In the upper region 126, the circumferential wall 106 has a maximum distance from the placement plane 28, with reference to the height axis 128 perpendicular to the placement plane 28.

[0111] The first region 118 extends in a first circumferential direction between the end region 124 and the lower region 122, having an angle range of 130, which is less than 180°, and particularly less than 150°.

[0112] Thus, the cleaning roller 32 can be positioned on the first region 118 without being clamped.

[0113] In one embodiment, the circumferential wall 106 is closed at the first region 118, that is, it is continuously formed without openings or similar structures.

[0114] The circumferential wall 106 has an inner side 132 facing the cleaning roller 32 and an outer side 134 away from the cleaning roller 32.

[0115] The second part 104 of the guide device 100 is installed on the outer side 134.

[0116] In particular, the second part 104 of the guiding device 100 is constructed as a guiding element in the form of a guide block, while the first part 102 is its mating element. The second part 104 and the first part 102 are configured cooperatively such that the guiding direction of the guide device 100 on the housing 92 in the housing holder 98 is parallel to the axis 108, that is, parallel to the rotation axis 96. The direction transverse to the axis 108 or transverse to the rotation axis 96 of the cleaning roller 32 is maintained by the corresponding side recess 136.

[0117] In one embodiment, an interface 138 of a wetting device 140 is arranged in a first region 118 of the circumferential wall 106, in a region of the second end portion 112. The wetting device 140 allows cleaning fluid from the tank device 44 to be applied directly and, in particular, indirectly, via the cleaning roller 32 to the surface 16 to be cleaned. In an advantageous embodiment, during operation of the surface cleaning device 10, the cleaning fluid is applied to the cleaning roller 32 via a nozzle device 142 disposed on the circumferential wall 106 and therein in the first region 118.

[0118] The fluid action of the portion of the wetting device 140 positioned outside the housing 92 on the cleaning head 14 is achieved via interface 138.

[0119] The second region 120 is configured as a flip cover 144 (see, for example, see...) Figures 7 to 13 The flap is supported in a movable manner at the first region 118 of the circumferential wall 106 via a swing bearing device 146.

[0120] The swing axis 148 of the swing bearing assembly 146 is oriented parallel to axis 108, and thus also parallel to the rotation axis 96.

[0121] In one embodiment, the oscillating bearing assembly 156 includes a plurality of spaced-apart oscillating bearings 150 oriented in alignment along an oscillating axis 148.

[0122] In the illustrated embodiment (see Figure 7 The device is equipped with three swing bearings 150.

[0123] In one embodiment, the oscillating bearing 150 includes a shaft element 152 disposed in a first region 118, and a receiving portion 154, each for the shaft element 152, disposed in a second region 120 and formed integrally, for example.

[0124] The second region 120 is configured as a flap 144. A spring device 156 is provided for the swing bearing device 146, wherein the spring force of the spring device 156 is used to press the flap 144 against the cleaning roller 32, thereby clamping the cleaning roller onto the holding device 94.

[0125] The flip cover 144 (second area 120) has a closed position 158 ( Figure 7 , Figure 10 , Figure 12 In this closed position, the flip cover 144 clamps the cleaning roller 32 onto the housing 92. The spring device 156 has a clamping force perpendicular to the axis of rotation 96 (perpendicular to axis 108) for clamping retention.

[0126] In the open position of the flip cover 144 (which is achieved by overcoming the spring force of the spring device 156, especially by manual operation by the operator), the cleaning roller 32 can be removed from the housing 92 (when the housing 92 is removed from the cleaning head 12). This open position... Figure 9 , Figure 11 and Figure 13 As shown in the image.

[0127] The flip cover 144 has a first end 160 and an opposite second end 162. The flip cover 144 is hinged to a first region 118 of the circumferential wall 106 via a swing bearing device 146 in the region of the first end 160.

[0128] In the closed position 158 of the flip cover 144, the second end 162 faces the placement plane 28 (see, for example, [reference needed]). Figure 10 ).

[0129] In the closed position 158 of the flap 144, the circumferential wall 106 has a second circumferential extension due to the first region 118 and the second region 120 (flip 144), which has an angle range 164 greater than 180°, for example greater than 200° (see Figure 12 ).

[0130] Thus, in the closed position 158, the cleaning roller 32 is prevented from detaching from the housing 92 in a direction transverse to the rotation axis 96 (transverse to axis 108). In the closed position 158, with respect to these directions transverse to the rotation axis 96, the cleaning roller 32 achieves form-locking on the holding device 94 via the circumferential wall 106 using its first region 118 and second region 120. The cleaning roller 32 is thus held in place on the housing 92.

[0131] The shape lock can be released by moving the flip cover 144 away. Figure 9 , Figure 11 , Figure 13 ).

[0132] A scraping device 166 for cleaning roller 32 is arranged on the flip cover.

[0133] The cleaning roller 32 is specifically configured as a wiping roller or a wet cleaning roller. It has a sleeve 168 (see...). Figure 13 The sleeve 168 has an open internal space 170. A lining 172, made of textile material, such as microfiber material, is mounted on the sleeve 168. During the cleaning operation of the surface cleaning device 10, the lining 172 is wetted with a cleaning solution (clean water or water with a surfactant) by the wetting device 140. By acting on the surface 16 to be cleaned, dirt can be dissolved and carried away by the lining 172 of the cleaning roller 32.

[0134] In principle, it is also possible that the cleaning roller 32 is a brush roller and is accordingly provided with brush bundles, or that the cleaning roller 32 has a mixed lining with a textile area and a brush area.

[0135] When the surface cleaning device 10 is in operation and the flip cover 144 is in the closed position 158, the scraping device 166 is pressed onto the cleaning roller 32 and thereupon the cleaning roller 32 is pressed onto the lining 172.

[0136] The scraping device 166 is arranged and configured such that the dirty fluid is stripped from the lining 172 of the cleaning roller 32 and guided to the inlet device 174. The scraping device 166 has both the function of stripping and guiding the dirty fluid.

[0137] Both the scraping device 166 and the swivel device 174 are mounted on the flip cover 144. The scraping device 166 here includes at least one scraper 176 (see...). Figure 13 When the surface cleaning equipment 10 is operating and the flip cover 144 is in the closed position 158 (and the housing 92 is inserted into the cleaning head 12 as specified), the scraper penetrates into the lining 172 of the cleaning roller 32. This in Figure 13The figure is indicated by reference numeral 178. The dirty fluid can be stripped from the lining 172 and guided away by the penetrating scraper 176.

[0138] The scraper 176 is arranged here, particularly on the flap 144, between the first end 160 and the second end 162, and is positioned here spaced apart from these two ends respectively.

[0139] The scraper extends almost along the entire length of the cleaning roller 32 (with the direction of the rotation axis 96 as its longitudinal axis).

[0140] The scraper 176 is arranged and configured to lead to the inlet device 174 in a funnel shape.

[0141] By means of the spring force of the spring device 156, the flip cover 144 is pressed against the lining surface 172 of the cleaning roller 32, and the scraper 176 is pressed into the lining surface 172 to achieve penetration 178. This creates a scraping device 176 under spring load.

[0142] Thus, for example, manufacturing tolerances in the cleaning roller or wear on the cleaning roller 32 can be compensated, because the spring-loaded oscillating bearing device 146 enables the scraper 176 to be correctly positioned on the cleaning roller 32 in the functions of dirt removal and dirt removal.

[0143] When the housing 92 is positioned on the cleaning head 12 as intended, the inlet device 174 (when the flap 144 is in the closed position 158) is positioned to allow the dirty fluid to be directly introduced into the tank device 42 for the dirty fluid. Specifically, the transport of the dirty fluid from the cleaning roller 32 to the tank device 42 is achieved without a blower via a direct coupling of a transport path 180 from the housing 92, and in this case, from the inlet device 174 on the flap 144 of the housing 92, to the tank device 42 (see, for example, [reference needed]). Figure 23 ).

[0144] The receiving section 84, the casing 92, and the canister device 42 and their components are designed here to automatically couple the opening device 174 of the casing 92 with the fluid action of the canister device 42 when the casing 92 is correctly placed into the receiving section 84, for filling the canister device 42 with dirty fluid.

[0145] On the retaining device 94 (of the housing 92), an edge flange 180 is arranged on the end side of the second end portion 112. This edge flange 180 (see, for example, [reference needed]). Figure 8 A contact surface for the cleaning roller 32 is formed about the axial axis 108. When the cleaning roller 32 is against the circumferential wall 106, the edge flange 180 prevents the cleaning roller 32 from falling off the housing 92 in the direction 108.

[0146] The housing 92 (holding device 94) has a rotating bearing 182 at the first end side end 110 (see...). Figure 15 The cleaning roller 32 is inserted into the rotary bearing 182 in a way that resists relative rotation, for rotation about the axis of rotation 96. The rotary bearing 192 is a fixed component of the housing 92 and is located away from the edge flange 180.

[0147] To secure the cleaning roller to the housing 92, the cleaning roller 32 is first inserted into the rotating bearing 182 when the flap 144 is open, and then pressed against the circumferential wall 106, particularly against the first region 118 of the circumferential wall 106. This pushes the cleaning roller past the edge flange 180, which provides an axial contact surface. The flap 144 is then closed, i.e., placed in the closed position 158 (see, for example, [reference needed]). Figure 10 Thus, the cleaning roller 32 is fixed to the housing 92. The housing 92 can then be pushed into the receiving portion 84. When the cover 90 is open (see...), Figure 5 and Figure 6 The housing is placed onto the housing holder 98 and pushed into the receiving portion 84 along the insertion direction 184 until it is secured about the axial axis 108. This will still be described in detail below. The insertion is performed at or via the second lateral side 82.

[0148] The insertion direction 184 is at least approximately parallel to the axis of rotation 96.

[0149] The assembly of the housing 92 and the cleaning roller 32 fixed thereon is placed into the receiving part 84.

[0150] To remove the housing 92 with the cleaning roller 32, the cover 90 is opened, and then the axial fastening is released. This will still be described in detail below.

[0151] In particular, when the axial fixation is released, the housing 92 and the cleaning roller 32 are fed together, causing them to extend beyond the second lateral side 82. Thus, the housing 92 with the cleaning roller 32 can be completely removed.

[0152] Take out direction 186 ( Figure 5 ) is the opposite direction of insertion direction 184, and is antiparallel to that insertion direction.

[0153] The removal is carried out at the opening 88, away from the transverse wall 86.

[0154] Then, the cleaning roller 32 can be removed from the housing 92 and cleaned, for example, in a washing machine.

[0155] As the housing 92 with the cleaning roller 32 is inserted along the insertion direction 184 until axial fixation is achieved, the interface 138 on the housing is automatically connected to the remaining parts of the wetting device 140 on the cleaning head 12 via fluid action. The cleaning roller 32 is automatically coupled to the drive device via torque action. Automatic orientation of the port device 174 is achieved for fluid action coupling with the tank device 42 for dirty fluid.

[0156] When the housing 92 with the cleaning roller 32 is removed and the axial fixation is released accordingly, the following are achieved: automatic disengagement of the interface 138 from the rest of the wetting device 140, removal of the cleaning roller 32 from the torque transmission device, and automatic release of the fluid coupling between the port device 174 and the tank device 42.

[0157] The housing 92 has a support side 188 with a rotary bearing 182 at its first end 110. Oppositely, it has a support drive side 190. An edge flange 180 is located on the support drive side 190. The support drive side 190 enables torque coupling between the cleaning roller 32 and the drive motor for rotation about the rotation axis 96.

[0158] The edge flange 180 and the circumferential wall 106 are designed so that the cleaning roller 32 can be driven to rotate about the axis of rotation 96 on the housing 92 even when the flip cover 144 is in the closed position 158.

[0159] In one embodiment, the interface 138 is located at or near the edge flange 180. A securing device 192 is provided to axially secure the housing 92 within the receiving portion 84, causing the housing 92 to be secured within the receiving portion 84 with respect to the insertion direction 184 and the removal direction 186. The guide device 100 causes fixation in all its lateral directions.

[0160] The retaining device 192 here has a first portion 194, which is arranged outside the housing 92 and associated with the transverse wall 86. The first portion 194 of the retaining device 192 is fixedly arranged on the cleaning head body 14 such that it cannot be removed from the cleaning head body 14. In embodiments, particularly those with a movable housing retainer, the first portion 194 itself may be movable, or it may be positioned as a whole in a non-movable manner on the cleaning head body 14.

[0161] In the illustrated embodiment, the first portion 194 of the fixing device 192 is arranged on the housing retainer 98 (see, for example, see...). Figure 20 ).

[0162] In an alternative embodiment, particularly when the housing retainer 98 is fixed (in a non-movable manner) to the cleaning head body 14, the first part 194 of the fixing device 192 may also be arranged directly at the transverse wall 86 and positioned inside the receiving portion 84.

[0163] The second part 196 of the fixing device 192, corresponding to the first part 194, is arranged on the housing 92.

[0164] In one embodiment, the second portion 196 of the fixing device 192 includes a nose 198, and in particular a plurality of noses 198, which are mounted on the edge flange 180 and extend outward in particular away from the edge flange 180.

[0165] Surface cleaning device 10 includes drive motor 200 (see...) Figure 16 It is used to drive the cleaning roller 32 to rotate around the rotation axis 96 in a rotary manner.

[0166] In one embodiment (not shown in the figures), the drive motor 200 is arranged on the cleaning head body 14, and particularly in the front region 56. Torque transmission from the drive motor 200 to the cleaning roller 32 is achieved via a transmission mechanism, which includes, for example, a belt drive mechanism, and particularly a reduction gear mechanism. With the housing 92 fixed to the cleaning head 12, torque coupling is achieved at the support drive side 190 via a corresponding drive end bearing element, to which the cleaning roller 32 is fitted with its sleeve 168 in a way that resists relative rotation.

[0167] In the illustrated embodiment, the drive motor 200 is a built-in motor for the cleaning roller 32. The drive motor 200 is a fixed component of the cleaning head 12 and is located in the rear region 54.

[0168] There is a connection to the control device via a control line, and there is an electrical connection to the battery device 70.

[0169] In particular, when the housing retainer 98 is movable (as described in detail below), the drive motor 200 is fixedly connected to the housing retainer 98 and can move together with the housing retainer.

[0170] When the housing retainer 98 cannot move, the drive motor 200 is arranged, for example, at the transverse wall 86, and is connected to the transverse wall directly or indirectly.

[0171] The drive motor 200 is positioned in the housing 84 and extends in a specific area about a longitudinal axis parallel to the rotation axis 96.

[0172] A motor drive component 202 is provided, which is positioned within the internal space 170 of the sleeve 168 when the cleaning roller 32 is fitted onto the drive motor 200. The motor drive component 202 is coupled to the cleaning roller 32 in a way that resists relative rotation.

[0173] In one variant of the embodiment ( Figure 19 The cleaning roller 32 is provided with a drive motor 204, which is external to the sleeve 168 of the cleaning roller 32. A drive member 206 is coupled to the drive motor 204 in a way that resists relative rotation and extends into the sleeve 168 of the corresponding cleaning roller 32.

[0174] The housing 92 is axially fixed to the cleaning head body 14 away from the second lateral side 82 via the fixing device 192. Thus, especially above the opening 88, no space is needed for the fixing device between the housing 92 and the cleaning head body 14. This space can then be used, for example, for the can 44, or the cleaning head 12 can be positioned at a smaller height parallel to the height axis 128.

[0175] In one embodiment, the retaining device 192 is configured as a press-type latching device 208 (“press-release touch latch”). A “press-release” mechanism is provided by the press-type latching device 208 (also referred to as a “press-release latch”) positioned in the region of the transverse wall 86. Axial fixation can be achieved, and axial fixation can be released (for removal of the housing 92 from the receiving portion 84) by applying pressure to the housing 92, wherein the pressure application is performed along a pressure application direction at least approximately parallel to the insertion direction 184. Furthermore, pressure can also be applied to the housing 92 in the region of the opening 88, that is, at a “larger” distance from the retaining device 192.

[0176] The fixing area for the housing 92, which is axially fixed relative to the cleaning head 14 (about axis 108), is specifically located at the end of the receiving portion 84, and is located in the receiving portion 84 or in the extension line of the receiving portion 84 in front of the transverse wall 86. Thus, the space already present in the receiving portion 84 is optimized for positioning the fixing device 192.

[0177] Press-fit fasteners are known in themselves and are used, for example, in furniture manufacturing.

[0178] In one embodiment, the push-button snap-fit ​​device 208 includes a housing 210 at the first portion 194. The housing 210 has a receiving portion facing the receiving portion 84 for the nose 198. The nose can be placed in the receiving portion of the housing 210 and axially secured in a snap-fit ​​manner. The connection can be released by applying pressure in a direction parallel to the insertion device 194.

[0179] It is possible to configure a spring device on the housing 210, which provides a feed when the housing 92 is disconnected and "pops out" the housing to a certain extent.

[0180] The push-button latching device 208 can be constructed in a relatively small size along a direction parallel to the axis 108, so that it can be positioned at the end of the receiving portion 84 as described.

[0181] The feed rate generated by the press-type latching device 208 is at least 0.5 mm, and preferably at least 1 mm. A larger feed rate is more advantageous.

[0182] As will be explained below, an additional feeding device 212 may be provided, which, in addition to the feeding of the press-type latching device 208, causes further feeding so as to cause the housing 92 to pop out "further" when the fixing device 192 is released, and in particular, to pop out through the opening 88.

[0183] The cover 90 is used to close the receiving portion 84 at the opening 88. The cover also serves to prevent the housing 92 from accidentally becoming detached. For example, there is a possibility, in principle, that in the "press-to-release" mechanism of the press-type latching device 208, an object colliding with the housing 92 in the area of ​​the opening 88 would generate pressure acting on the housing 92 in the direction of the transverse wall 86, thereby causing the housing 92 to become detached. With the cover 90 closed, this risk does not exist.

[0184] In one embodiment, the cover 90 is fixedly (to prevent loss) connected to the cleaning head body 14. A corresponding hinge 214 is provided for this purpose, having a swing axis 216. In one embodiment, the swing axis 216 is oriented laterally and, in particular, perpendicularly to the placement plane 28. The swing axis is oriented laterally and, in particular, perpendicularly to the insertion device 184 or the removal direction 186. The swing axis is oriented laterally and, in particular, perpendicularly to the rotation axis 96. The swing axis is oriented laterally and, in particular, perpendicularly to the main travel direction 26.

[0185] In particular, the cover is arranged laterally via hinge 214 and, for example, on the side on which the housing retainer 98 is also oriented on the cleaning head body 14.

[0186] When the lid is 90 degrees open ( Figure 5 , Figure 6 ), the cover 90 pivots from the rear end 38 to the front end 36.

[0187] The hinge 214 is, for example, spring-loaded, to achieve a good closure of the opening 88 at the second lateral side 82.

[0188] In particular, it is designed so that when the lid is closed at 90 degrees ( Figure 4The cover 90 is spaced apart from the housing 92 and from the second end 112, so that no pressure (which could trigger the "press-release" mechanism of the fixing device 192) is applied to the housing 92.

[0189] In order to secure the cartridge 92 (together with the cleaning roller 32) in the receiving portion 84, the cartridge 92 is pushed into the receiving portion 84 in the insertion direction 184 when the cover 90 is opened. The cartridge 92 is oriented such that the first portion 102 and the second portion 104 of the guide device 100 are engaged with each other.

[0190] The housing 92 is pushed along the insertion direction 184 until the first part 194 and the second part 196 of the fixing device 192 (press-type snap-fit ​​device 208) correspond to each other and achieve axial fixation.

[0191] This can be perceived auditorily through a clicking sound.

[0192] To remove case 92, close cover 90. Figure 4 Starting from the opening 88, the cover 90 is opened. Then, in the area of ​​the opening 88, the cartridge 92 is pressed with a pressure direction at least approximately parallel to the insertion direction 184. This causes the fixation on the retaining device 192 to be released, and the connection between the first part 194 and the second part 196 to be released. The cartridge 92 is detached from the cleaning head body 14. In the illustrated embodiment, the cartridge 92 is detached from the cartridge holder 98 in the axial direction 108.

[0193] In one embodiment, the fixing device 192 is also configured to, upon release of the fixing, impart a feed to the housing 92 in a direction parallel to the removal direction 186.

[0194] In one embodiment, additionally or alternatively, the cleaning roller 32 is equipped with a feeding device 218. In one embodiment ( Figure 16 The feed device 218 is positioned in the internal space 170 of the sleeve 168.

[0195] The feeding device 218 has a spring device 220, which is supported both on the cleaning roller 32 (within the sleeve 168) and on the drive motor 200, specifically at the end of the drive motor 200. When the cartridge 92 is positioned as intended on the cleaning head 12, the spring device 220 is under compression. For example, the spring device is compressed during insertion. When the cartridge 92 is released from the fixing device 192, the spring device 220 relaxes and, through its action on the cleaning roller 32, imparts a feed to the cartridge 92, and in particular, an additional feed.

[0196] The feed rate is at least 0.5 cm, preferably at least 1 cm, and especially at least 2 cm.

[0197] The drive motor 200 is arranged on the cleaning head 12 in a non-detachable manner. The drive motor provides a support surface for the spring device 220, which ensures that the housing 92 moves or undergoes additional movement in the removal direction 186 when the fixation by the fixing device 192 is released.

[0198] In particular, when releasing the fixation via the fixing device 192, especially via the "press-release" mechanism, the overall feed of the case 92 causes the case 92 to protrude beyond the second lateral side 82 through the opening 88. This allows the operator to more easily grasp the case 92 and then pull it completely out of the receiving portion 84 in the removal direction 186.

[0199] The total feed can be generated solely by the press-type latching device 208, solely by the feed device 218, or a total feed consisting of the individual feeds of the press-type latching device 208 and the feed device 218, depending on the construction scheme.

[0200] As an alternative to the swingable cover 90, it is also possible to provide a cover 222 (Fig. 26(a)) that can be completely removed from the cleaning head body 14 (Fig. 26(b)). In particular, the cover 222 is held on the cleaning head body 14 by a pin element on the cover or on the cleaning head body 14.

[0201] In another embodiment ( Figures 27 to 2 In 9(b)), the cover 224 is fixedly arranged on the box body 92.

[0202] The cover 224 is arranged and constructed such that no pressure is applied to the housing 92 via it (which could cause accidental release of the fasteners on the fixing device 192). For example, the cover 222 is arranged on the housing 92 in a swingable manner (see Figures 28(a) and 28(b)). A conversion mechanism (not shown) is provided that converts the swing of the cover 222 (according to Figure 28(b)) into the application of pressure to the housing 92 parallel to the insertion direction 184. Thus, the fasteners on the housing 92 can be released by means of the cover 224.

[0203] In another embodiment (Figures 29(a) and 29(b)), a cover 226 is provided, which is mounted on the housing 92 in a linearly movable manner. The linear movement of the cover 226 (Figure 29(b)) then generates pressure parallel to the insertion direction 184 via a conversion mechanism, which in turn causes the release of the fixation on the fixing device 192 and, if necessary, causes feeding along the removal direction 186.

[0204] The box 92 can be removed with the cover 224 or 226 attached.

[0205] A receiving wall 228 is provided on the cleaning head body 14 (see, for example, see...). Figure 23 and Figure 24 The receiving portion 84 is formed through the receiving wall. In principle, it is possible that the case holder 98 is formed via the receiving wall 228, and in particular, the first part of the guide device 100 may be arranged on or formed by the receiving wall 228.

[0206] In one embodiment, the housing retainer 98 is separate from the receiving wall 228 and is positioned movable within the receiving portion 84.

[0207] A swing bearing device 230 is provided, which enables the housing retainer 98 to be supported on the cleaning head 14 in a swinging motion.

[0208] Oscillating axis 232 (see Figure 21 This axis is parallel to axis 108, or rather, parallel to axis of rotation 96. The swing axis is transverse to, and in particular perpendicular to, the insertion direction 184 or the removal direction 186. The swing axis is transverse to, and in particular perpendicular to, the main travel direction 26.

[0209] The swing axis 232 is parallel to the placement plane 28.

[0210] The housing retainer 98 has a wall 234 (see Figure 21 , Figure 23 The first part 102 of the guide device 100 is formed on the inner side of the wall 234.

[0211] A transverse region 236 is provided on wall 234 (see Figure 21 , Figure 22 The lateral region 236 holds the first portion 194 of the fixing device 192. The lateral region 236 also holds the drive motor 200 via a corresponding retainer 238.

[0212] In an alternative embodiment where the drive motor is mounted on the cleaning head body 14 outside the receiving portion 84, torque coupling with the transmission mechanism is achieved via the lateral region 236.

[0213] Spacing tabs 242 are arranged on the outer side 240 of the wall 234. These tabs extend outward from the wall 234 and are away from the receiving part 84.

[0214] In one embodiment (see Figure 21 These tabs 242 are constructed in an arc shape. These tabs 242 form the oscillating bearing assembly 230, and in particular, the portion mounted on the housing retainer 98. This portion cooperates with another portion mounted on the cleaning head body 14.

[0215] The receiving wall 228 has an opening 244 that cooperates with the tab 242. Each opening 244 is passed through by a tab 242 (or, in the case of an arc, by a tab assembly). Thus, the mating member 246 relative to the tab 242 (by means of which the swing bearing device 230 is formed) is fixedly positioned on the cleaning head body 14 outside the receiving portion 84, as described above.

[0216] Thus, the receiving portion 84 is positioned between the oscillating bearing assembly 230 and the rear end portion 38 of the cleaning head 12. When the housing 92, along with the cleaning roller 32, is mounted on the cleaning head 12, the housing is positioned between the oscillating bearing assembly 230 and the can assembly 42.

[0217] The mating part 246 of the swing bearing device 230 is particularly installed on the front region 56 of the cleaning head body 14.

[0218] In the illustrated embodiment, two mating parts 246 are provided for cooperating with two tabs or tab assemblies 242.

[0219] The oscillating bearing assembly 230 is equipped with a spring assembly 248. In particular, each oscillating bearing of the oscillating bearing assembly 230, which consists of a mating member 256 and an associated tab or tab assembly 242, is equipped with (at least one) spring, such as a helical spring.

[0220] The spring device 248 is arranged and configured to apply a spring force that presses the housing retainer 98 against the placement plane 28.

[0221] In principle, the cleaning roller 32 is pressed against the surface 16 to be cleaned during cleaning operation, especially on the ground, and the force used is predetermined by the gravity of the cleaning head 12. The cleaning roller 32 can be pressed against the surface 16 to be cleaned using an additional force provided by the spring device 248 via a movable housing retainer 98 having a swing bearing device 230 and a spring device 248. This results in improved cleaning performance.

[0222] In one embodiment, the additional force is set to be in the range of 7N to 17N.

[0223] The cleaning roller 32 can be supported by a spring load via the housing retainer 98, allowing it to move. This enables a floating support of the cleaning roller 32 on the cleaning head 12. As a result, it is possible for the cleaning roller 32 (by movement of the housing retainer 98) to avoid obstacles by briefly lifting (raising upward) off the surface 16 via the housing retainer 98.

[0224] The spring force of the spring device 248 causes a brief maintenance of the lift during this lifting, and once the obstruction is removed, the housing retainer 98 moves toward the placement plane 28 and presses the cleaning roller 32 onto the surface to be cleaned.

[0225] In principle, it is possible to match the spring device 248 to the application. The spring force should not be too large to prevent the cleaning head body 14 from lifting, that is, it must be kept on the placement plane 28. For example, in principle, it is possible that a smaller spring force is sufficient for a floating support, rather than expecting a stronger press of the cleaning roller 32 onto the surface 16 to be cleaned.

[0226] The placement plane 28 is pre-defined by the wheel 20 and the support roller 24. The brush roller 30 rests against the placement plane 28. When the cartridge holder 98 is not movable, the cleaning roller 32 also rests against the placement plane 28.

[0227] In the solution according to the invention, which has a movable cartridge holder 98, the cleaning roller 32 is in principle only in contact with the placement plane 28 when the cleaning head 12 is placed on the surface 16. When the cleaning head 12 is lifted, the spring force of the spring device causes the cleaning roller 32 to be pushed downwards beyond the placement plane until it reaches the end stop.

[0228] Surface cleaning equipment 10 includes an active lifting device 250 (see...) Figure 3 ), so that the housing holder 98 is lifted in a direction away from the placement plane 28, thereby spaced the cleaning roller 32, in particular, from the placement plane 28 and from the surface 16 (see Figure 24 In this position 252, the cleaning roller 32 does not touch the surface 16. This may be meaningful, for example, when pure carpet cleaning should be performed via the brush roller 30. The lifting device 250 can make the cleaning roller 32 non-active with respect to surface contact.

[0229] The corresponding location 252 may also be meaningful, for example, when the surface cleaning equipment 10, and especially the cleaning roller 32, is to be cleaned at a site (ground station).

[0230] In one embodiment, the lifting device is configured as a rope traction device 254. This rope traction device includes a traction rope 256. The traction rope 256 is connected via a fastening element 258 (…). Figure 3 , Figures 21 to 23 It is fixed to the box holder 98 on the end side.

[0231] Fastening element 258 is installed in the upper region at wall 234. This results in space-saving access.

[0232] The fastening element 258 is arranged, in particular, at least approximately centered, between the opposite ends of the housing retainer 98.

[0233] The rope traction device 254 also includes a motor 260 with a transmission mechanism. The motor 260 is located in the front region 56 of the cleaning head body 14, and particularly in the region of the battery device 70.

[0234] In one embodiment, with reference to longitudinal axis 40, motor 260 is positioned between the receiving portion 58 for the sludge collection container and the front end portion 36 of the cleaning head body 14.

[0235] Motor 260 is specifically positioned near the fan unit 62.

[0236] In addition, in one embodiment, the motor 260 is arranged on the same side as the fan unit 62.

[0237] The traction rope 256 is guided along the housing 58 via the first region 262. Then, its direction is changed at the second region 264. The second region 264 is specifically guided above the fan assembly 62.

[0238] Another direction change is made at the third region 266, and coupled to the motor 260.

[0239] By activating the motor 260 and applying corresponding tension to the traction rope 256, the housing retainer 98 with the housing 92 equipped with the cleaning roller 32 can be lifted. It is pulled upwards ( Figure 24 ), to reach position 252.

[0240] The motor 260 maintains this position 252. In particular, this position 252 is maintained even when the motor 260 is not running (not supplied with electrical power).

[0241] In particular, it is configured such that, in order to guide the housing from position 252 and to lower the housing retainer 98, motor 260 needs to be activated. Motor 260 then causes the tension to be canceled to some extent by rotating in the opposite direction to the lifting direction, and thus the spring device 248 causes the descent.

[0242] In one embodiment, the rope traction device 254 includes a pulley element 268. The pulley element 268 is arranged, for example, at a first region 262 of the traction rope 256.

[0243] In one embodiment, pulley element 268 is arranged in the rear region 54 of the cleaning head body 14.

[0244] It is located particularly close to the housing area at location 58 (see...) Figure 3 ).

[0245] The pulley element 268 has a displacement element 270 that is supported in a movable manner. In one embodiment, the displacement direction 272 is oriented parallel to the axis of rotation 96.

[0246] The displacement direction is 272, especially the linear direction.

[0247] The first traction rope 274 is guided at the displacement element 270 via a loop 276. The displacement element 270 is a roller for the first traction rope 274.

[0248] The first traction rope 274 is fixedly connected to the cleaning head body 14 at one end 278 (if a spring device is used if necessary) and, for example, at the rear region 54.

[0249] At the other end 280, the first traction rope 274 is connected to the motor 260. Figure 25 The diagram illustrates motor 260, whose actual positioning is based on... Figure 3 (As shown.)

[0250] Return line 276 is located between ends 278 and 280.

[0251] The second traction rope 282 is fixedly connected to the displacement element 270 at its corresponding end 284. At the other end, it is connected to the fastening element 258.

[0252] By activating motor 260, displacement element 270 is moved along displacement direction 272. This actuates second traction rope 282, applying tension to it, thereby raising housing retainer 98. Reset is then performed accordingly.

[0253] By using pulley element 268, the required motor force is halved, resulting in a doubling of the stroke.

[0254] The first traction rope 274 and the second traction rope 282 constitute the traction rope 256. A first region 262 of the traction rope 256 includes a portion of the second traction rope 282 and the first traction rope 274. A second region 264 and a third region 266 are formed at the first traction rope 274.

[0255] In one embodiment, the first traction rope 274 is secured to the cleaning head body 14 via a spring device 286. The spring device 286 ensures that the first traction rope 274 is continuously under tension.

[0256] The surface cleaning device 10 described above is a self-propelled and self-steering floor cleaning machine. The solutions according to the invention, particularly the flip cover 144, the "press-to-release" fixing device 192, and the movable and spring-supported support for the housing retainer 98, can also be applied individually or in combination to other types of surface cleaning devices, such as those guided by a standing operator's hand via a lever mechanism.

[0257] The surface cleaning device 10 according to the present invention functions as follows:

[0258] For cleaning operation, the cleaning roller 32 is placed into the housing 92 located outside the cleaning head 12. To do this, the flip cover 144 is opened, and then the cleaning roller 32 is placed into the housing 92. This achieves the following: Figure 7 The state shown.

[0259] The cleaning roller 32 is held in the housing 92 by the flip cover 144.

[0260] In addition, the scraping device 166 and the opening device 174 are also integrated into the flip cover 144. When the surface cleaning device 10 is in operation, at least one scraper 176 is pressed against, or in particular pressed into, the lining 172 of the cleaning roller 32.

[0261] After securing the cleaning roller 32 in the housing 92, the operator pushes the housing 92, carrying the cleaning roller 32, into the receiving portion 84. To do this, the cover 90 is opened and the housing 92 is pushed in. Pushing the housing in here causes the second portion 104 of the guide device 100 to engage with the first portion 102.

[0262] Move the housing 92 toward the transverse wall 86 along the insertion direction 184 until the fixing device 192 can be engaged. The first part 194 of the fixing device 192 is connected to the second part 196 on the housing 92.

[0263] Thus, the housing 92 is fixed about axis 108 in the receiving part 84. At the same time, this establishes a fluid connection between the wetting device 140 and the housing 92, aligns the inlet device 174 with the can device 42, and couples the drive motor 200 with the cleaning roller 32 to resist relative rotation.

[0264] Close the lid at 90 degrees.

[0265] Then you can perform a clean run.

[0266] A movable cartridge retainer supported by a spring device 248 allows the cleaning roller 32 to be pressed against the surface 16 to be cleaned during cleaning operation. This achieves a floating support, increasing the contact force for improved cleaning results.

[0267] The cleaning roller 32 can be lifted via the rope traction device 254. This renders the cleaning roller in a non-functional state (see [link]). Figure 24 ).

[0268] For example, when the cleaning process should only be performed on the textile surface, the cleaning roller 32 is deactivated accordingly. The operator makes the necessary adjustments, and the control device activates the rope traction device 254, or the sensor identifies the surface type (such as the ground type) and automatically and autonomously activates the rope traction device 254 when the textile surface is detected, so as to reach the position 252 of the cleaning roller 32.

[0269] After the cleaning process is complete, the operator can remove the cleaning roller 32 for washing, for example, in a washing machine. To do this, the operator opens the cover 90. This is done by directing water into the corresponding end 288 of the housing 92 or the cleaning roller 32 through the opening 88 (see...). Figure 5 Applying pressure, the operator releases the fixing device 192. The push-button latching device 208 provides a "press-release" mechanism.

[0270] In addition to releasing the fixing device 192, a feed also occurs, which can be enhanced by the feed device 212.

[0271] In particular, the cartridge 92 with the cleaning roller 32 is then pushed out of the opening 88 slightly to make it easier to remove.

[0272] The operator can then remove the housing 92 containing the dirty cleaning roller (see, for example, the case of the cleaning roller). Figure 7 By flipping up the cover 144, the operator can remove the cleaning roller 32 from the housing 92.
