Description

[0001] The invention relates to a cleaning device, in particular a cleaning robot, with a removable collection container. Furthermore, the invention relates to a collection container for a cleaning device.

[0002] A cleaning device, particularly a suction device, typically has a suction nozzle with a suction port through which impurities or dirt, particularly dust particles, are sucked up from a surface to be cleaned by means of an air stream. The air stream can be generated by a fan. The air stream transports the dirt from the suction port, via a suction channel, into a dirt collection container of the cleaning device.

[0003] For example, DE 10 2017 208 969 A1 is known from the prior art, which discloses a dust separation unit for a vacuum cleaner or robotic vacuum cleaner, which has at least one locking unit for the releasable fixing of the dust separation unit to the vacuum cleaner.

[0004] To empty the collection container, the user of the cleaning device can remove it from the device and take it to a waste bin. It is possible that some dirt particles may unintentionally fall out of the container through an opening during removal.

[0005] This document addresses the technical task of providing a collection container and a cleaning device with a collection container that allows for convenient and safe removal of the collection container without allowing dirt particles to fall out of the collection container.

[0006] The problem is solved by the subject matter of the individual independent patent claims. Advantageous embodiments are defined in particular in the dependent patent claims, described in the following description, or illustrated in the accompanying drawings.

[0007] According to one aspect, a collection container is described that is designed to be inserted into a cleaning device, in particular into a cleaning robot, and that is designed to receive dirt particles during the cleaning operation of the cleaning device. The cleaning device has a container recess into which the collection container can be inserted.

[0008] The collection container comprises a base container, which typically has a filter unit. The filter unit can be designed to retain dirt particles from the suction air flow of the cleaning device in the base container. The fan of the cleaning device (for generating the suction air flow) can be arranged downstream of the filter unit in the flow direction. The base container can be cuboid-shaped or cylindrical, for example.

[0009] The base container can have a drain opening for emptying the base container. The suction air flow containing the dirt particles can enter the collection container through the drain opening. The suction air flow can be drawn through the filter unit, so that the dirt particles are retained by the filter unit in the base container of the collection container.

[0010] The collection container includes a lid designed to cover the base container, particularly its emptying opening, thus preventing dirt particles from falling out of the collection container. The lid may optionally be pivotally mounted on the base container via a pivot axis. The lid may have a suction channel opening (optionally closable by a flap) for receiving the suction airflow containing the dirt particles.

[0011] The collection container further comprises at least one guide element designed to interact with at least one complementary guide element of the container recess of the cleaning device, such that when the collection container is removed from the container recess by the guide element, it is automatically transferred from a (substantially and / or predominantly) horizontal orientation to a tilted orientation (with the lid facing upwards). In the horizontal orientation, the lid and the base container of the collection container can be arranged at (at least almost) the same height relative to the cleaning device. In the tilted orientation, the lid can be arranged higher relative to the cleaning device (at least partially or at least the highest point) than the base container.

[0012] The lid can be arranged along the longitudinal axis of the collection container opposite the base area of ​​the base container. In other words, the collection container can have a longitudinal axis that extends from the base area of ​​the base container to the lid. The cleaning device can have a longitudinal axis that, during cleaning operation of the cleaning device, is (substantially and / or predominantly) parallel to the surface being cleaned by the cleaning device (and that typically corresponds to the direction of movement of the cleaning device). For example, during cleaning operation of the cleaning device, the longitudinal axis of the cleaning device can have an angle to the surface being cleaned by the cleaning device that is less than 10°, preferably less than 5° or less than 2°.In general, it should be noted that when it is described in this document that two axes and / or directions are (substantially) parallel, this preferably means that the two axes and / or directions have an angle to each other which is less than 10°, preferably less than 5° or less than 2°.

[0013] In the horizontal orientation of the collection container, the longitudinal axis of the collection container can be aligned (substantially and / or almost) parallel to the longitudinal axis of the cleaning device (with a tilt angle of (almost) zero, e.g., with a tilt angle of 10° or less, in particular 5° or less, or 2° or less). On the other hand, in the tilted orientation, the longitudinal axis of the collection container and the longitudinal axis of the cleaning device can form a tilt angle greater than zero. The tilt angle can be 20° or more, in particular 40° or more.

[0014] Thus, a collection container is described that has one or more guide elements that automatically tilt the collection container (with the lid facing upwards) when it is removed from the container recess of the cleaning device. This allows for convenient and safe removal of the collection container.

[0015] The collection container can have at least one guide pin as a guide element on at least one side wall, which is designed to engage in a corresponding guide rail (in particular in a guide groove) on at least one side wall of the container recess. The side wall of the collection container can be arranged (essentially and / or predominantly and / or almost) parallel to the longitudinal axis of the collection container. Correspondingly, the side wall of the container recess can be arranged (essentially and / or predominantly and / or almost) parallel to the longitudinal axis of the cleaning device. By providing one or more guide pins, the tilting of the collection container during removal can be achieved in a particularly efficient manner.

[0016] The collection container typically has two opposing side walls along the transverse axis of the collection container. Correspondingly, the container recess typically has two opposing side walls. The collection container preferably has at least one guide pin, in particular two guide pins, on each of the two side walls. This allows the collection container to be tilted particularly reliably during removal.

[0017] The collection container can have a front guide pin facing the lid and a rear guide pin facing away from the lid on one or both side walls. The rear guide pin can be positioned higher relative to the vertical axis of the collection container, in particular 30% or more of the total height of the collection container (along the vertical axis), than the front guide pin. By using two guide pins (on both side walls) positioned at different heights, the collection container can be tilted during removal in a particularly reliable manner.

[0018] As already explained above, the lid can be pivotally mounted on the base container via a pivot axis. The collection container can have an elastic seal that is attached to the inner wall of the base container and to the inner wall of the lid, covering the pivot axis. This provides a particularly reliable way to prevent contamination and jamming of the pivot axis.

[0019] According to a further aspect, a cleaning device, in particular a cleaning robot, is described. The cleaning device typically comprises a cleaning unit (e.g., a suction unit) configured to clean a surface, e.g., a surface on which the cleaning device is arranged and / or on which the cleaning device moves (optionally autonomously). The cleaning device may further comprise the collection container described in this document for receiving dirt particles. Furthermore, the cleaning device may comprise a suction channel that fluidically connects the cleaning unit to the collection container, and a fan configured to effect a suction air flow through the cleaning unit and through the suction channel to the collection container.

[0020] The cleaning device comprises, in particular, a container recess for accommodating a collection container for dirt particles. Furthermore, the cleaning device comprises at least one guide element configured to interact with at least one complementary guide element of the collection container, so that when the collection container is removed from the container recess, the guide element automatically converts it from a horizontal orientation to a tilted orientation (with the lid of the collection container facing upwards).

[0021] As already explained, the cleaning device can have at least one guide rail (in particular a guide groove) as a guide element on at least one side wall of the container recess, which is designed to receive the corresponding guide pin on a side wall of the collection container. The at least one guide rail can extend from the top of the cleaning device along the vertical axis of the cleaning device into the container recess. Furthermore, the guide rail on the top of the cleaning device can have a funnel-shaped enlargement, which facilitates the threading of the corresponding guide pin (when inserting the collection container).

[0022] The container recess typically has two opposite side walls along the transverse axis of the cleaning device. Preferably, the container recess has at least one guide rail on each of the two side walls, in particular at least two guide rails on each side. This allows the collection container to be tilted particularly reliably during removal.

[0023] The cleaning device can have, on one or both side walls of the container recess (each) along the longitudinal axis of the cleaning device, a first front guide rail facing the lid of the collecting container and a rear guide rail facing away from the lid. The rear guide rail can run straight along the vertical axis of the cleaning device into the container recess at a rear position. The first front guide rail can run from a front position on the top side of the cleaning device along the vertical axis of the cleaning device into the container recess. The first front guide rail can be curved from the front position towards the rear position with increasing penetration depth into the container recess.By providing a curved guide rail, the tilting of the collection container when removed can be achieved in a particularly efficient and reliable manner.

[0024] The cleaning device may have a second (straight) front guide rail on one or both side walls of the container recess (each), which runs along the vertical axis of the cleaning device parallel to the rear guide rail into the container recess (at a position arranged between the rear and the front position).

[0025] The second front guide rail can merge with the first (curved) front guide rail at a specific penetration depth into the container recess. A switch can be arranged at this specific penetration depth. The switch can be designed (e.g., by using a spring that holds the switch in a defined position) such that • a guide pin is guided from the second front guide rail to the first front guide rail when inserting the collection container into the container recess from the specific penetration depth (through the switch) (so that the collection container can be inserted into the container recess in the horizontal orientation); and • the guide pin is guided past the second front guide rail when removing the collection container from the container recess (through the switch) and is held in the first front guide rail (so that the collection container is transferred into the tilted orientation when removed from the container recess).

[0026] By providing a second front (straight) guide rail, the convenience of inserting and removing the collection container can be further increased.

[0027] It should be noted that any aspects of the collection container and / or cleaning device described in this document can be combined with one another in a variety of ways and / or in any way. In particular, the features of the claims can be combined with one another in a variety of ways and / or in any way.

[0028] The invention will be described in more detail below with reference to exemplary embodiments illustrated in the accompanying drawings. Figures 1a and 1b an exemplary cleaning robot as an example of a cleaning and / or suction device in different perspective views; Figure 1c exemplary components of a cleaning device; Figures 2a to 2e an exemplary collection container and an exemplary container recess of a cleaning device; Figures 3a to 3c exemplary guide rails; Figures 4a to 4cexemplary guide certificates with a guide switch; and Figures 5a to 5b a collecting container with a seal.

[0029] As stated at the outset, this document deals with preventing the unintentional spillage of dirt from a collection container when the container is removed from a cleaning device in an efficient and reliable manner. In this context, we demonstrate Fig. 1a the top 121 and Fig. 1b The underside 122 of a cleaning robot 100 serves as an example of a cleaning device, in particular as an example of a suction device. The aspects described specifically for a cleaning robot apply generally to a cleaning device.

[0030] During vacuuming operation of the cleaning robot 100, the underside 122 faces the floor to be cleaned or the surface of a cleaning area, such as a room, to be cleaned. The underside 122 of the cleaning robot 100 typically has one or more drive units 101 (with one or more drive wheels), by means of which the cleaning robot 100 can be moved independently to clean different areas of a floor. Furthermore, the cleaning robot 100 can have one or more guide and / or support elements 104 (e.g., non-driven wheels) that enable stable movement of the cleaning robot 100 over the floor to be cleaned. In addition, a cleaning robot 100 typically comprises one or more cleaning units 106 (in particular, suction nozzles) that are configured to clean the floor beneath the cleaning robot 100.

[0031] A cleaning unit 106 (in particular a suction nozzle) may include a brush roller 102 configured to rotate about a rotational axis, wherein the rotational axis is typically arranged parallel to the underside 122 of the cleaning robot 100. The brush roller 102 may be used to mechanically remove dust and / or contaminants from the floor to be cleaned, so that the dust and / or contaminants can be sucked into the suction mouth 107 of the cleaning unit 106 with increased reliability.

[0032] A user interface can be arranged on the top side 121 of the cleaning robot 100, which allows a user of the cleaning robot 100 to make control inputs. Furthermore, the cleaning robot 100 can comprise a bumper 105 on a side wall 123 (e.g., on a side wall 123 in the front area of ​​the cleaning robot 100). A bumper sensor can be arranged on the bumper 105 and is configured to capture sensor data indicating whether or not the cleaning robot 100 has encountered an obstacle in the direction of movement 120. Triggering the bumper sensor (due to the deflection of the bumper 105) by an obstacle can, for example, cause the cleaning robot 100 to rotate about its vertical or vertical axis, which is perpendicular to the floor, and thereby change the direction of movement 120 to avoid the obstacle.

[0033] Furthermore, a cleaning robot 100 typically has one or more environment sensors 110 (see Fig. 1c), which are configured to acquire environmental and / or sensor data relating to the environment of the cleaning robot 100. The one or more environmental sensors 110 may include: one or more cameras, one or more ultrasonic sensors, one or more tactile and / or optical distance sensors, one or more acoustic sensors, one or more temperature sensors, one or more lidar and / or radar sensors, etc. A control unit 130 of the cleaning robot 100 may be configured to determine digital map information relating to the cleaning area based on the environmental data and, if necessary, to store it on a storage unit 111 of the cleaning robot 100. The cleaning robot 100 can use the digital map information to orient itself independently within the cleaning area (e.g., within a room) and / or to determine a route for cleaning the cleaning area.

[0034] Fig. 1cshows a Cartesian coordinate system with a longitudinal axis (i.e., an x-axis), a transverse axis (i.e., a y-axis), and a vertical axis (i.e., a z-axis). The direction of movement 120 of the cleaning device 100 typically corresponds to the longitudinal axis. The rotational axis of the brush roller 102 typically runs along the transverse axis.

[0035] The cleaning device 100 typically has a collecting container 140, which can be inserted into a container recess 150 of the cleaning device 100 or removed from the container recess 150 of the cleaning device 100. In the Figures 2a and 2b illustrates how the collecting container 140 can be removed from the container recess 150 of the cleaning device 100. Furthermore, Figures 2c and 2d an exemplary container recess 150 with guide rails (in particular grooves) 221, 222 and Fig. 2eshows an exemplary collection container 140 with corresponding guide pins 211, 212, which can be moved in the corresponding guide rails 221, 222 when removing or inserting the collection container 140.

[0036] The collection container 140 can have a base container 205 that can be covered with a lid 202. The lid 202 can be pivotally mounted on the base container 205, for example, via a joint and / or a pivot axis. A handle 204 for opening the lid 202 and / or for removing the collection container 140 from the container recess 150 can be arranged on the lid 202. The base container 205 can have a filter unit 203 on a container wall through which suction air is drawn. The filter unit 203 can be designed to filter out dirt particles that were sucked into the collection container 140 by the cleaning device 100 via the suction mouth 107 from the suction air, so that the dirt particles remain in the collection container 140.

[0037] A suction channel opening 201 can be arranged on the collection container 140, in particular on the lid 202 of the collection container 140, through which the suction air (with the dirt particles) enters the collection container 140. A flap can be provided on the suction channel opening 201, with which the suction channel opening 201 can be closed (when the cleaning device 100 is not operating in cleaning mode). The flap can be designed such that it opens automatically (e.g., due to the suction air flow) when the cleaning device 100 is operating in cleaning mode.

[0038] It may happen, particularly if the suction channel opening 201 of the collecting container 140 cannot be covered with a flap, that dirt particles fall out of the collecting container 140 when the collecting container 140 is removed from the container recess 150, e.g., when the collecting container 140 is removed horizontally or with the suction channel opening 201 facing downwards. The collecting container 140 and the container recess 150 can therefore be designed such that the suction channel opening 201 and / or the lid 202 are automatically aligned upwards when the collecting container 140 is removed. This can be achieved by the Figures 2c and 2d Guide rails 221, 222 shown and the Fig. 2e illustrated guide pins 211, 212 (general guide elements).

[0039] The collection container 140 can have a longitudinal axis extending from the base of the main container 205 to the lid 202 of the collection container 140, in particular to the emptying opening of the main container 205. The hinge of the collection container 140 can be configured to pivot the lid about a pivot axis that runs parallel to the transverse axis of the collection container 140. The vertical axis of the collection container 140 can be arranged perpendicular to the longitudinal and transverse axes. In the installed state of the collection container 140: the longitudinal axis of the collection container 140 can correspond to the longitudinal axis of the cleaning device 100, the transverse axis of the collection container 140 can correspond to the transverse axis of the cleaning device 100, and / or the vertical axis of the collection container 140 can correspond to the vertical axis of the cleaning device 100.

[0040] The collection container 140 can, for example, have a cuboid shape. Furthermore, the collection container 140 can have a first side wall and an opposite second side wall along the transverse axis. Two pins 211, 212 can be arranged on each of the two side walls. The container recess 150 is typically designed to correspond to and / or complement the shape of the collection container 140. The container recess 150 can have a first side wall and an opposite second side wall along the transverse axis (of the cleaning device 100). Two guide rails 221, 222 (for the corresponding pins 212, 212 of the collection container 140) can be arranged in each of the two side walls.

[0041] A front pin 211 and a rear pin 212 (relative to the longitudinal axis) can be arranged on the side walls of the collecting container 140, wherein the front pin 211 is arranged closer to the suction channel opening 201 than the rear pin 212. The rear pin 212 can be arranged higher relative to the vertical axis than the front pin 211.

[0042] In a corresponding manner, a front guide rail 221 (for the respective front pin 211) and a rear guide rail 222 (for the respective rear pin 212) can be arranged on the side walls of the container recess 150 (with respect to the longitudinal axis), wherein the front rail 221 is arranged closer to the suction channel than the rear rail 222.

[0043] In the Figures 3a to 3c different arrangements of the pins 211, 212 in the corresponding rails 221, 222 when removing the collecting container 140 from the container recess 150 are shown. Fig. 3a shows the arrangement of the pins 211, 212 when the collection container 140 is fully inserted into the container recess 150 (e.g., during the cleaning operation of the cleaning device 100). The collection container 140 is in the horizontal orientation.

[0044] Fig. 3b illustrates a situation in which the collecting container 140 has been lifted horizontally (ie with the longitudinal axis aligned horizontally). Due to the curvature of the front rail 221, the collecting container 140 can only be lifted horizontally to a certain height. From the height shown in Fig. 3b At the point shown, the collecting container 140 must be rotated backwards around the transverse axis in order to increase the effective distance between the two pins 211, 212 (along the longitudinal axis of the cleaning device 100). Only then can the collecting container 140 be raised further out of the container recess 150, as shown by way of example in Fig. 3c shown.

[0045] In the Figures 4a to 4e An example is shown in which the side walls of the container recess 150 each have a second front guide rail 421, which allows the collection container 140 to be inserted horizontally into the container recess 150. The container recess 150 has a first front rail 221 on each side wall, which has a curvature to force the collection container 140 to tilt when removed. Furthermore, each side wall has a second front rail 421, which allows the collection container 140 to be inserted horizontally into the container recess 150.

[0046] The two front guide rails 221, 421 are preferably separated from each other by a partition 401 and a movably mounted (on a pivot axis 402) switch 403. By default, the switch 403 can close access to the second front rail 421 when the collecting container 140 is inserted, so that the front pin 211 is guided along the first front rail 221 when the collecting container 140 is removed. On the other hand, the switch 403 can be deflected by the front pin 211, starting from the second front rail 421, when the collecting container 140 is inserted, in order to transfer the collecting container 140 horizontally along the second front rail 421 into the inserted state.

[0047] Measures are thus described which make it possible to automatically tilt the dust box 140 (i.e., the collection container 140 in general) during removal. Tilting the dust box 140 causes any dust and dirt contained therein to be moved away from the front flap 202 to the rear wall (i.e., the base) of the dust box 140. The tilting movement allows the dust to be reliably released from the filter unit 203 of the dust box 140. Furthermore, it can be ensured that the dust is no longer located in the area of ​​the front flap 202 (i.e., the lid) and thus cannot fall out of the dust box 140 when the user opens the front flap 140.

[0048] The dust box 140 can be designed such that the dust box 140 can be pulled upwards out of the cleaning robot 100. The dust box 140 has a front flap 202 that allows the contents of the dust box 140 to be completely emptied.

[0049] A guide is integrated into the cleaning robot 100, along which the dust box 140 is moved when it is removed from or inserted into the cleaning robot 100. This guide is at least partially not straight, but rather has one or more curves designed such that the dust box 140 is tilted upward about the transverse axis (with the front flap 202) during removal from the cleaning robot 100.

[0050] For this purpose, guide pins 211, 212, e.g., sliding blocks, can be provided on the dust box 140. Furthermore, the corresponding guide rails 221, 222 (e.g., grooves) can be arranged in the cleaning robot 100. The one or more curves of the guide rails 221, 222 can be designed such that the dust box 140 is not only moved vertically but is also simultaneously tilted about the transverse axis. For the user, this appears as a continuous movement, which can be perceived, for example, as a locking step.

[0051] When removing the dust box 140 upwards, the front, lower edge of the dust box 140 is in the Figures 3a to 3c In the example shown, the dust box 140 is guided upwards in a curved path. During this movement, the dust box 140 tilts, so that the front of the dust box 140 is raised. Dust falls into the rear area of ​​the dust box 140 and remains there. Upon completion of the guided removal movement, the dust box 140 can be freely removed upwards by the user. If the user continues to hold the dust box 140 in this orientation on the way to a trash can, it can be ensured that the dust does not fall out unexpectedly when the front flap 202 is opened.

[0052] When reinserting the dust box 140 into the cleaning robot 100, the dust box 140 in the example of Figures 3a to 3cIt is inserted into the cleaning robot 100 in a tilted orientation and is then returned to the horizontal and / or horizontal orientation during the further downward movement. The cleaning robot 100 is preferably provided with funnel-shaped insertion openings in the guide rails 221, 222 to facilitate threading the corresponding pins 211, 212 of the dust box 140.

[0053] The curved shape of the guide rails 221, 222 is preferably designed such that the guide rails 221, 222 force the dust box 140 to tilt upon removal, and when the dust box 140 is inserted, wedging and / or hooking of the guide pins 211, 212 is reliably prevented. The curve responsible for tilting the dust box 140 is preferably designed to force a displacement of the front guide pins 211 before the rear guide pins 212 can be lifted out of the corresponding guide rails 222. The curved curve therefore begins relatively early (i.e., relatively far down within the container recess 150). When reinserting the dust box 140, wedging can be prevented by the (front) guide rails 221 being designed to be relatively wide (along the longitudinal axis) in order to allow sufficient play during insertion and when pushed downwards by the user.

[0054] The tipping motion during lifting can be supported by the design of one or more handles 204 on the dust box 140. If the dust box 140 has a handle 204 only on its front edge or in the front area, the weight distribution relative to the handle 204 alone will automatically cause the dust box 140 to tip when it is lifted out.

[0055] Alternatively or additionally, the guide rails 221, 222 on the cleaning robot 100 can be designed in such a way that the dust box 140 is tilted when removed, but can also be inserted horizontally when inserted into the cleaning robot 100 (as shown for example in the Figures 4a to 4e(shown). Similar to a track switch system, the front guide pins 211 of the dust box 140 are guided forward on their upward path. During insertion, the guide pins 211 can also take a straight downward path, bypassing or pushing away the switch 403. The switch 403 can be pressed into its desired position by spring force.

[0056] This gives the user the option of reinserting the empty dust box 140 into the cleaning robot 100 in a horizontal position, which enables particularly convenient and intuitive handling.

[0057] When inserted horizontally, the (front) guide pin 211 slides vertically downward into the rear, second channel 421 of the front guide rail 221, 421 (i.e., into the second front guide rail 421). The spring-loaded switch 403 is pushed to the side, allowing the guide pin 211 to slide past the switch 403. When the dust box 140 is removed, the guide pin 211 is forced by the switch 403 into the front, first channel 221 of the front guide rail 221, 421 (i.e., into the first front guide rail 221), tilting the dust box 140.

[0058] In the event that the front flap 202 of the dust box 140 is swung open downwards with the swivel axis 501 (as shown for example in the Figures 5a and 5bshown), it is possible that when the dust box 140 is emptied, dirt and dust may pass over the edge of the base container 205 onto the front flap 202. To prevent the seals on the flap 202 from becoming dirty, a flexible seal 502 can be integrated between the base container 205 and the front flap 202, which is tightened or tensioned when the front flap 202 is opened, so that a continuous, smooth transition is created between the base container 205 and the flap 202.

[0059] The automatic tilting of the dust box 140 described in this document moves dust and dirt to the rear of the dust box 140, preventing them from falling out when the front flap 202 is opened. Tilting the dust box 140 can provide an additional cleaning effect for the filter unit 203, particularly for removing relatively large pieces of lint.
