Technical Field

The invention relates to a suction cleaning device, in particular an autonomous vacuum cleaning robot, having a device housing in which a fan and a filter chamber for receiving suction material sucked by means of the fan are arranged, wherein the filter chamber has a chamber closure element for reversibly closing a chamber opening of the filter chamber, and wherein the device housing has a housing closure element, which is independent of the chamber closure element, for reversibly closing a housing opening of the device housing, through which the chamber opening of the filter chamber is accessible from outside the suction cleaning device.

Background

Such suction cleaning devices are known in the prior art. They usually have a filter chamber with a so-called permanent filter which remains permanently in the suction cleaning device and can be regenerated by means of a base station or other suction cleaning devices. The filter chamber is evacuated and can be used for the suction cleaning device to be operated again.

In order to evacuate the filter chamber of the suction cleaning device by means of the base station or even a fan of another suction cleaning device, the device housing of the suction cleaning device is first opened to provide access to the filter chamber enclosed by the device housing. Subsequently, the chamber opening of the filter cavity is opened to enable evacuation of the filter cavity.

A disadvantage of such a suction cleaning device is that the user or the base station must first move the housing closure element and then also the chamber closure element, since the housing closure element does not simultaneously form the chamber closure element of the filter chamber. The filter chamber is then opened for the regeneration process.

Disclosure of Invention

Starting from the prior art described above, the object of the invention is to make the regeneration process for evacuating the filter chamber easier, in particular to make it easier to reach the interior space of the filter chamber.

In order to solve the above-mentioned problem, it is proposed according to the invention that the chamber closing element and the housing closing element are mechanically coupled to one another in such a way that a displacement movement of the housing closing element relative to the housing opening simultaneously also brings about a displacement movement of the chamber closing element relative to the chamber opening, wherein the chamber closing element is mounted on the housing closing element so as to be movable relative to the housing closing element.

According to the invention, the housing closing element and the chamber closing element are mechanically coupled to one another in such a way that, upon a displacement movement of the housing closing element, the chamber closing element is displaced so that the chamber opening can be connected to a suction connection of a base station or other suction cleaning device, wherein the displacement movement can be performed manually by a user or automatically by a servo mechanism of the suction cleaning device. The filter chamber can thus be accessed by only one actuating movement, i.e. the displacement of the housing closure element, which forms a partial region of the exterior of the device housing of the suction cleaning device.

Preferably, the housing opening is formed on the upper side of the device housing, with reference to the usual orientation of the suction cleaning device during the suction operation. In this case, the housing closing element preferably forms a plane with the adjacent housing partial region of the device housing with reference to the closed state of the housing opening. The housing opening formed on the upper side of the device housing achieves an optimal accessibility of the housing opening by the user or even by the base station in order to connect the suction connection to the filter chamber of the suction cleaning device to be regenerated. In the closed state of the housing opening of the suction cleaning device, the surface of the housing of the device preferably forms a flat surface in which the housing closure element is arranged flush alongside the adjacent housing partial region, so that the upper side of the housing of the device is easy to clean and offers little possibility for dust and dirt to accumulate.

It is proposed that the housing closure element is mounted on the device housing in a linearly displaceable manner. The opening of the housing opening is thus achieved by a displacement of the housing closure element relative to the device housing, wherein a displacement movement of the housing closure element also simultaneously leads to a displacement of the chamber closure element. When the housing closure element is displaced, the chamber closure element is preferably first lifted off the chamber opening or the seal sealing the chamber opening, before the chamber closure element is slid relative to the chamber opening.

In particular, it is proposed that the chamber closing element is mechanically operatively connected to the housing closing element by a follower, so that the chamber closing element is simultaneously displaced when the housing closing element is displaced. The proposed follower couples the housing closure element and the chamber closure element to one another in such a way that, when the housing closure element is displaced, the chamber closure element is also displaced together. The user or the base station merely has to displace the housing closure element, whereby the displacement of the chamber closure element then also takes place automatically. The follower can preferably be firmly fixed to the housing closure element, for example by means of a screw connection or a latching connection, so that relative movement between the housing closure element and the follower is not possible. The housing closing element can be moved relative to the housing closing element in such a way that the housing closing element is moved relative to the housing closing element. The chamber closing element can thus be lifted off the chamber opening or the associated seal in a direction different from the sliding direction.

It is proposed that the suction cleaning device has a guide device for mechanically guiding the displacement movement of the housing closure element and/or the follower. The guiding means may be a guiding runner formed or arranged in the device housing. The guide device may have, for example, a guide groove, in which the follower or a corresponding partial region of the housing closing element can slide. Preferably, a partial region of the follower is guided in the guide runner, wherein the housing closing element is in turn indirectly supported on the guide device via the follower. Alternatively, however, a local region of the housing closing element can also be guided in the guide device.

The follower preferably additionally has a guide track in which the connecting element of the chamber closing element is guided movably. A guide track inside the follower effects a lifting of the chamber closure element from the filter chamber, wherein the direction of the lifting movement differs from the displacement movement caused by the guide device. In addition to the transmission of the displacement movement of the housing closing element to the chamber closing element, the follower therefore also has the task of transmitting a force to the chamber closing element, which force causes the chamber closing element to follow the guide track and to be detached from or lifted off the chamber opening. The guide groove of the guide device and the guide track of the follower are oriented relative to one another in such a way that, when a force is applied to the housing closure element in the opening direction, the chamber closure element is first caused to be displaced along the guide track of the follower and then along the guide device. However, both movements may also be at least partially simultaneous.

Preferably, the chamber closing element is supported relative to the housing closing element by means of a spring element, wherein the restoring force of the spring element is directed away from the housing closing element. In this way, the spring element, which is preferably designed as a compression spring, is arranged between the housing closure element and the chamber closure element, both in terms of space and also in terms of mode of action. For example, the spring element may be a helical spring, a leaf spring or the like. The spring element presses the chamber closing element against a partial region of the filter chamber or a sealing element surrounding the chamber opening, so that the chamber opening is preferably closed dust-tight and gas-tight. The spring element is supported on the housing closure element.

Furthermore, it is proposed that the guide device is equipped with a restoring element which is provided to apply a restoring force in the closing direction to a partial region of the housing closure element and/or the follower which is guided by means of the guide device. The restoring element can be, for example, a tension spring which is tensioned during the opening movement of the housing closure element and then, as soon as the force acting in the opening direction on the housing closure element disappears, pulls the housing closure element or the follower guided in the guide back into an initial position, which corresponds to the closed state of the housing opening and the chamber opening. Provision can be made for the guide device to have more than one restoring element. If the guide device is designed, for example, as a guide frame which circumferentially surrounds the housing closure element, or has two partial elements which delimit the chamber opening and the housing opening from both sides, it is possible to provide a separate restoring element opposite a partial region of the guide frame or to assign each guide partial element to its own.

It is particularly proposed that the housing closure element has a guide ramp on the underside facing the interior of the device housing, which guide ramp can slide over an adjacent housing partial region of the device housing when the housing closure element is moved in a displacement manner in the opening direction. The slope of the guide ramp preferably corresponds to the slope of the guide means, wherein the slope is preferably dimensioned such that the housing closure element is displaced at the smallest possible angle relative to the adjacent partial region of the device housing. Preferably, a slope of 0.1 to 5 degrees is specified. However, slopes of up to 10 degrees may also be provided. When displaced into the open position, the housing closure element is held as close as possible to the upper side of the device housing, so that it does not collide with a partial region of the base station, the vacuum cleaner performing the regeneration or even the user. Alternatively or additionally, however, it can also be provided that the housing closure element enters a recess or a cover of the device housing.

Finally, it is proposed that the housing closure element has a handling region which is spaced apart from an adjacent housing subregion of the device housing, so that a displacement force can be applied to the handling region in the opening direction of the housing closure element. If the actuating region of the housing closure element lies in the plane of the device housing, a recess, in particular a groove, can be provided next to the housing closure element, for example, which can reach the actuating region. It is important that the actuating region is arranged such that a force can act on the actuating region, said force acting in the displacement direction of the housing closure element, i.e. in the opening direction of the housing opening.

Detailed Description

Fig. 1 to 6 show by way of example a suction cleaning device 1 in the form of an autonomous travelling vacuum cleaner robot with motor-driven wheels 21 (see fig. 4 to 6) for autonomous travelling. Furthermore, the vacuum cleaning apparatus 1 has a navigation device, not shown, by means of which the vacuum cleaning apparatus 1 can be oriented and positioned in the environment. For this purpose, the suction cleaning device 1 has, for example, a distance measuring device, for example a laser triangulation device, which can measure the distance to obstacles present in the environment. From the measured distance values, the computing means of the suction cleaning device 1 generate an environment map with which the suction cleaning device 1 can plan a travel path in the environment or position itself. However, the invention described below is not only used for an autonomously traveling suction cleaning device 1, but also for a suction cleaning device 1 which is guided manually by the user's hand. The invention is applicable in principle to all suction cleaning devices 1 which have a regenerable filter chamber 4, the filter chamber 4 being evacuable by an external suction device 20.

The suction cleaning device 1 shown here has a device housing 2 in which a fan 3 and a filter chamber 4 are arranged. The fan 3 is provided with an electric motor, not shown further. The filter chamber 4 is connected to the suction opening 23 via a suction channel 24. In the suction operation of the suction cleaning device 1, suction sucked up from the surface to be cleaned can enter the filter chamber 4 via the suction opening 23 and the suction channel 24, wherein only the cleaned air then flows to the fan 3. The suction opening 23 is assigned cleaning elements 22, in this case for example a bristle roller rotating about a substantially horizontal axis, for the mechanical treatment of the surface to be cleaned. In addition to the exemplary illustrated cleaning element 22 or as an alternative thereto, the suction cleaning device 1 can also have other or further cleaning elements 22, for example wiping elements and/or cleaning elements 22 rotating about a substantially vertical axis. In order to avoid collisions with obstacles in the environment, the suction cleaning device 1 preferably has an obstacle sensor, not shown, for example an ultrasonic sensor. The sensor is preferably arranged on the device housing 2 of the suction cleaning device 1 in the front with respect to the normal forward movement of the suction cleaning device 1.

On the upper side 9 of the device housing 2, a housing closure element 7 is arranged, which housing closure element 7 reversibly closes the housing opening 8. When the housing opening 8 is open, a user or an external suction device 20 can reach the filter chamber 4 arranged in the device housing 2, i.e. to the chamber opening 6, the chamber opening 6 being exposed to the inlet inside the filter chamber 4 in the open state of the chamber closure element 5.

As fig. 4 to 6 show, the housing opening 8 and the chamber opening 6 are spaced apart from one another and are separately constructed with the housing closure element 7 on one side and the chamber closure element 5 on the other side.

The housing closing element 7 and the chamber closing element 5 are mechanically coupled to one another by, for example, two guides 12 and two followers 10. This is illustrated by figures 7 to 10. Fig. 7 shows in particular an exploded view of a partial region of the suction cleaning device 1, which partial region has the filter chamber 4 and the housing partial region 15, the housing partial region 15 delimiting the housing opening 8. For the mechanical coupling, the housing closing element 7 and the chamber closing element 5 are connected by a follower 10, which has a flange, not shown in detail, which is mounted in a guide 12. The guide means 12 are designed as guide grooves which have an acute angle with respect to the bottom or underside 19 of the housing closure element 7. The two followers 10 and the two guides 12 are opposite each other with respect to the housing opening 8 or the cavity opening 6. A spring element 11 is also arranged between the housing closing element 7 and the chamber closing element 5 located therebelow, said spring element 11 being designed here as a compression spring and the restoring force of the compression spring pushing the chamber closing element 5 away from the housing closing element 7. The chamber closing element 5 is in particular pressed against a sealing element 25 of the filter chamber 4, which surrounds the edge of the chamber opening 6. The housing closing element 7 is immovably connected to a follower 10 supported in a guide 12. Instead, the chamber closing element 5 is mounted movably on the follower 10, i.e. by means of a connecting element 18, said connecting element 18 engaging in the guide track 13 of the follower 10. When the housing opening 8 or the chamber opening 6 is opened, the displaceable mounting of the chamber closing element 5 on the follower 10 firstly effects a lifting of the chamber closing element 5 from the sealing element 25, acting substantially in the vertical direction, and then, with the opening movement of the housing closing element 7 or the chamber closing element 5 continuing, effects a displacement movement of the chamber closing element 5 along the guide 12, i.e. a displacement movement which is substantially horizontally or slightly upwardly directed. The follower 10 is connected to the guide 12 by means of a restoring element 17, i.e. in this case, for example, a tension spring, wherein the restoring element 17 is tensioned when the follower 10 is moved in the opening direction. When the opening force on the follower 10 disappears, the follower 10 is displaced again by the restoring force of the restoring element 17 into the initial position, which coincides with the closed state of the chamber closing element 5 and the housing closing element 7. The housing closure element 7 also has a guide ramp 16 on its underside 19, the guide ramp 16 (as shown in fig. 8 to 10) enabling the housing closure element 7 to be lifted out of the plane of the housing partial region 15 bounding the housing opening 8 and to slide at least partially over the adjacent housing partial region 15. On the side edge opposite the guide ramp 16, the housing closing element 7 has an actuating region 14, through which a force can be introduced, which leads to the opening of the housing opening 8. For example, a displaceable partial region of a base station or a suction device 20 guided manually by a user can act on the manipulation region 14.

Fig. 11 to 13 and 14 to 16 show in unique views (fig. 11 to 13) a partial region of the suction cleaning device 1 according to fig. 7 in the assembled state and integrated into the suction cleaning device 1 (fig. 14 to 16).

Now, for example, the invention functions in such a way that a user exerts a force on the actuating region 14 of the housing closure element 7 by means of a manually guided suction device 20, for example a suction nozzle of a hand-held vacuum cleaner. The application of force takes place substantially parallel to the upper side 9 of the device housing 2, so that the housing closure element 7 is moved by a follower 10 guided in a guide 12. In this case, the guide ramp 16 of the housing closure element 7 reaches above the adjacent housing part 15, while the housing closure element 7 moves along the rising guide 12. As shown first in fig. 5 and 9, the connecting element 18 of the chamber closing element 5 is displaced within the guide track 13 of the follower 10. The chamber closing element 5 is thereby lifted off the sealing element 25 of the chamber opening 6 and can then follow the guide 12 in a substantially horizontal direction. In the open position of the housing opening 8, the housing closure element 7 exposes an inlet into the device housing 2, i.e. in particular an inlet on the chamber opening 6 of the filter chamber 4, so that the external suction device 20 can be connected to the chamber opening 6 of the filter chamber 4 and regenerate. As soon as the force acting on the housing closing element 7, in particular on the actuating region 14, has disappeared, for example in that the external suction device 20 is removed from the actuating region 14, the follower 10 and the housing closing element 7 fastened thereto are pulled back from the open position shown in fig. 6 into the closed position according to fig. 4, by virtue of the restoring force of the restoring element 17 tensioned during the opening movement. Here, the spring element 11 arranged between the housing closing element 7 and the chamber closing element 5 likewise reduces the stress, the spring element 11 pressing the chamber closing element 5 back onto the sealing element 25. Here, the connecting element 18 of the chamber closing element 5 is at the same time displaced again in the guide track 13 of the follower 10. The chamber opening 6 is then closed again in an air-tight and dust-tight manner.

Fig. 17 shows a further embodiment of the suction cleaning device 1 according to the invention, wherein, in contrast to the embodiment according to fig. 7, the housing subregion 15 with the chamber opening 6 is designed with two parts. The upper partial region forms a housing outer wall, the housing closure element 7 lying in the plane of which housing outer wall the housing opening 8 is closed by the housing closure element 7. The lower part of the housing subregion 15 has the chamber opening 6 (and preferably also a sealing element 25, not shown) and a lateral receptacle 26 for the restoring element 17, the restoring element 17 serving for the return displacement of the housing closing element 7 and the chamber closing element 5 into the closed position. Contrary to the previous embodiments according to fig. 4 to 16, the follower 10 for the connection between the chamber closing element 5 and the housing closing element 7 is integrated in a guide frame 27, the guide frame 27 circumferentially surrounding the chamber opening 6 with respect to the closed position of the chamber closing element 5. The guide frame 27 with the housing closure element 7 can be displaced relative to the housing subregion 15 into the open position against the restoring force of the restoring element 17. In order to achieve a displacement of the coupling of the housing closing element 7 and the guide frame 27, the housing closing element 7 has a pin 28, the pin 28 being supported in a corresponding recess 29 of the guide frame 7. According to the illustration in fig. 18, the chamber closing element 5 is arranged (not shown) in the guide frame 27 and engages with its connecting element 18 in the guide track 13 of the guide frame 27 in order to achieve a vertical lifting-off of the chamber closing element 5 relative to the housing part area 15 before the guide frame 27 is displaced together with the housing closing element 7 and the chamber closing element 5 relative to the housing part area 15. The vertical displacement of the chamber closing element 5 relative to the housing closing element 7 is controlled by a spring element 11, the spring element 11 pressing the chamber closing element 5 against the edge region of the chamber opening 6 via a guide frame 27.

Fig. 19 shows a top view of the housing subregion 15 together with the housing closure element 7 in the closed position. The actuating region 14 can be seen, the actuating region 14 projecting as a stop element beyond the surface plane of the housing partial region 15 and being able to be gripped by a user or contacted by a partial region of an external suction cleaning device 1 or base station in order to displace the housing closure element 7 and the guide frame 27 located on the housing closure element 7 as a whole relative to the housing opening 8.

Finally, fig. 20 shows a further alternative embodiment of the suction cleaning device 1, which has a housing closure element 7, in which the chamber closure element 5 is accommodated in the housing closure element 7. The chamber closure element 5 is therefore surrounded by the housing closure element 7. The chamber closing element 5 is mounted so as to be movable relative to the housing closing element 7 in order to achieve an initial lifting of the chamber closing element 5 off the sealing element 25 of the chamber opening 6. For this purpose, the housing closing element 7 can in turn provide, for example, a guide track 13 (not shown) for a connecting element 18 (not shown) of the housing closing element 5. Alternatively, however, other types of guide runners can be provided inside the housing closure element 7, which guide runners allow a relative movement of the chamber closure element 5 with respect to the housing closure element 7. The housing closing element 7 is in turn moved along the guide means 12 relative to the housing partial region 15 and the chamber opening 6. The guide means 12 is, for example, a guide ramp formed on a housing partial region 15. The guide device 12 and/or the housing closing element 7 can in turn be assigned a restoring element 17 (or two restoring elements 17) which can displace the housing closing element 7 back into the closed position when the actuating force is removed.
