Description

Technical field

The present invention relates to a vacuum cleaner with a dust collector, which contains at least one locking device for detachably fixing the dust collector, a control device for the locking device and at least one transmission element for transmitting the movement of the control element to the locking device.

State of the art

For example, German patent application DE 102004019317 describes a dust collector for a vacuum cleaner with a self-returning handle, as a result of which the dust collector can be conveniently removed from the vacuum cleaner body.

In addition, patent application US 2003/0226228 describes a container with a lid and a carrying handle for use in a carpet care device. The U-shaped carrying handle is pivotally mounted on the container and can lock the lid.

In European patent application EP 1728460, for example, a device for fixing and separating a container with a centrifugal element is described. The device includes a handle and a lock / unlock device.

In addition, patent application US 2007/0186372 describes a vacuum cleaner with a dust chamber. So that the dust chamber can be removed from the vacuum cleaner body in order to clean it from dust and dirt, the user needs to unlock using two levers that are pre-stressed by springs. In this case, the ends of the levers are removed from two protrusions, as a result of which the dust chamber can be removed from the vacuum cleaner body.

US 2004/0205928 describes a vacuum cleaner with a removable container that is connected via a detachable connection to the upper part of the housing. In addition, the container includes a handle that is mounted on the container with the possibility of rotation between the first and second position. A stopper is installed on the vacuum cleaner, which fixes the container on the upper part of the body when the handle is in the first position, and disconnects the container from the upper part of the body when the handle is in the second position.

In addition, the German patent application DE 102004001028 describes a vacuum cleaner that includes a cover for the main body. A handle is provided on the cover of the main body, and hooks are formed on both sides of the handle, and corresponding grooves are formed in the corresponding places of the main body of the vacuum cleaner. If you insert the filter element into the mount or filter holder and press the handle down, the hooks will mesh with the grooves.

In addition, German patent application DE 102007008915 describes a vacuum cleaner with a removable dust-collecting container and a centrifugal separator. The centrifugal separator can be biased to remove the dust container. The centrifugal separator is held in position on the dust container with a protrusion that abuts the cutout of the locking element on the handle of the dust container. To remove the dust container, the user needs to push the button to remove the locking element from the protrusion region of the centrifugal separator, overcoming the spring force. As a result, the centrifugal separator will be released. Now the centrifugal separator can be tilted to the open position.

German patent application DE 10336829 describes a vacuum cleaner with a housing and a carrying handle. The carrying handle can be rotated relative to the housing between two end positions of the working rotation angle using at least one rotating support, which comprises a first part and a second part, which can be rotated relative to the first part about a common axis of rotation. The pivot bearing is designed to dock or separate the first part of the pivot bearing and the second part of the pivot bearing in a mounting angular position that lies outside the working angle of rotation.

Disclosure of invention

The objective of the invention is to provide a vacuum cleaner that compares favorably with the prior art. In particular, a vacuum cleaner should be developed whose latching dust collector can be removed from the vacuum cleaner by a simple action. In particular, ease of handling of the dust collector should be ensured. In addition, a vacuum cleaner with a dust collector should be developed, in which improper installation of the dust collector in the vacuum cleaner will be excluded.

The designations in all claims are not restrictive and serve only to improve understanding of the invention.

The tasks are solved with a vacuum cleaner with the features disclosed in paragraph 1 of the claims.

A vacuum cleaner is an electric device for collecting dust, and it can be powered by either an electrical network or a battery or accumulator. The vacuum cleaner may contain, for example, a unit consisting of an engine and a blower device for creating an intake air stream, a dust collecting nozzle, a channel directing an intake air stream, and a dust collector. A dust collector is understood to mean a device in which intake air containing dirt can be freed from dirt. For example, a dust collector may include a filter with or without a basket, a dust container and / or a centrifugal separator.

The dust collector described by the invention can be removed from the vacuum cleaner, for example, to remove collected dust, and reinserted into the vacuum cleaner. The locking device allows you to fix the dust collector on the vacuum cleaner during its operation. Advantageously, the locking device can be translated into the locking position, in which the dust collector can be fixed by the locking device on the vacuum cleaner. In order to be able to remove the dust collector from the vacuum cleaner, the locking device can advantageously be translated into the unlocking position in which the dust collector is not fixed to the vacuum cleaner.

Advantageously, the locking device described by the invention can be controlled by a control that can be translated into a holding position and an extraction position. Advantageously, the locking device is in the unlocked position when the control is in the ejection position, that is, the locking connection of the dust collector and the vacuum cleaner can be opened, and the dust collector can be removed from the vacuum cleaner. If the control is in the holding position, then the locking device is advantageously in the locking position, that is, the dust collector can be fixed to the vacuum cleaner, for example, during operation of the vacuum cleaner. Advantageously, the locking device comprises a locking and unlocking mechanism that can be actuated by the control.

The transmission element can improve control of the vacuum cleaner, since the locking device can be actuated independently of the control. With the same position (for example, the holding position) of the control, the locking device can be moved to the locking and / or unlocking position. Advantageously, the locking device can be moved to the locking and / or unlocking position when the control is in the holding position. As a result, in an advantageous manner, the dust collector can be installed in the vacuum cleaner regardless of the position of the control element, which makes it easier to handle the vacuum cleaner. So, for example, it is possible to exclude a situation in which the locking device is in the locking position when installing the dust collector and blocks the installation. As a result, it is possible to prevent the user from handling the dust collector improperly, which may lead to damage to the vacuum cleaner or dust collector.

A possible advantage of the vacuum cleaner described by the invention is that the transmission element allows you to transfer the movement of the control to the locking device in order to establish or open the locking connection between the dust collector and the vacuum cleaner. In this case, the control body and the locking device can move in different directions or even in different ways. So, for example, rotational motion can be transformed into translational, and translational - into rotational. This may be considered an advantage since the design of the control may not depend on the locking device.

Another possible advantage may be the possibility of actuating the locking device by means of a handle, since the handle can be used both to unlock the locking device and thereby open the locking connection between the dust collector and the vacuum cleaner, and to remove or carry the dust collector. Advantageously, the handle can be used to carry and / or unlock / lock the dust collector on the vacuum cleaner. As a result, the use of the vacuum cleaner can be facilitated, since the user, holding the handle, can unlock and remove the dust collector. This can be especially beneficial because the user would already intuitively grab the handle to remove the dust collector. Advantageously, the user does not have to think about how to unlock the dust collector.

Advantageous embodiments of the invention, which can be used individually or in combination with each other, are disclosed in the dependent claims.

In a preferred embodiment, the control is rotatably mounted. As a result, the user can rotate the control made in the form of a handle to remove the dust collector. In this case, by means of the transmission element and the locking device, the fixing connection between the dust collector and the vacuum cleaner will be opened. In a particularly preferred embodiment, the control may be rotated by the holding position and the extraction position. Advantageously, the user can remove the dust collector from the vacuum cleaner using the control in the extraction position.

In a further preferred embodiment, the dust collector comprises a recess in which the control element is included. In a particularly preferred embodiment, the control in the holding position is located in the recess. Due to this, during operation of the vacuum cleaner, that is, with the dust collector installed, the control is in the recess and does not protrude from the vacuum cleaner. As a result, in an advantageous manner, damage to the control element during operation of the vacuum cleaner can be prevented. In addition, you can give the vacuum cleaner an attractive appearance.

In a further preferred embodiment, the transmission element is in the form of a transmission mechanism. The transmission mechanism allows you to convert the movement of one type, for example, rotational or translational, in the movement of another type. Usually for this moving parts are interconnected. In addition to mechanical devices, hydraulic, pneumatic or electromagnetic transmission mechanisms can be used. Advantageously, the transmission mechanism can transmit the movement of the control to the locking device. So, for example, the rotation of the control corresponding to rotation can be converted into translational motion in order to fix the dust collector on the vacuum cleaner.

In a further embodiment of the invention, the transmission element may be in the form of a wedge mechanism. Advantageously, the wedge mechanism allows a simple and / or easily manufactured transmission element to be realized. Advantageously, the wedge mechanism may differ in mechanical strength, due to which it is possible to ensure a long service life of the transmission element.

In a preferred embodiment of the invention, the control comprises a leash engaged with the wedge mechanism. In a particularly preferred embodiment, the leash is adjacent to the grip surface of the wedge mechanism. As a result, the movement of the control can be transmitted by a wedge mechanism to a locking device. Advantageously, the leash is adjacent to the surface of the wedge mechanism so that the locking device can move to the locking and / or unlocking position regardless of the control even when the control is in the holding position, for example, with the handle folded. As a result, the user can advantageously install the dust collector in the vacuum cleaner regardless of the position of the control.

According to the invention, preferably, the locking device comprises an elastically deformable element. An elastically deformable element can be made, for example, in the form of a spring. As a result, it is possible to realize the possibility of transferring the locking device to a specific position using an elastically deformable element. Advantageously, the locking device can be translated by means of an elastically deformable element into the locking position in which it will fix the dust collector on the vacuum cleaner. Advantageously, the locking device when installing the dust collector in the vacuum cleaner can be transferred from the locking position to the unlocking position, overcoming the force developed by the elastically deformable element. This will allow the elastically deformable element to return to the locked position when the dust collector is installed in the operating position. Advantageously, the locking device is deflected upon installation by means of a vacuum cleaner element.

In a further preferred embodiment of the invention, the dust collector comprises two locking devices which are located on opposite sides of the dust collector. As a result, in an advantageous manner, at least two locking devices are arranged symmetrically on the dust collector. Due to this, a uniform fixation of the dust collector on the vacuum cleaner is achieved and, thereby, a mechanically stable position of the dust collector in the vacuum cleaner.

In a further preferred embodiment of the invention, the locking device comprises at least one fixing element for fixing the dust collector to the vacuum cleaner. In a particularly preferred embodiment, the locking element is made in the form of a bolt. Of course, the invention allows the use of other options for the locking element. In a particularly preferred embodiment, at least one part of the locking element extends into the interacting element of the vacuum cleaner. In a particularly preferred embodiment, the fixing element for the purpose of fixing the dust collector on the vacuum cleaner enters the corresponding hole on the vacuum cleaner. Advantageously, the locking element allows for mechanically stable fixing of the dust collector on the vacuum cleaner.

The locking element in a preferred embodiment is biasably mounted. In a particularly preferred embodiment, the dust collector can be fixed on the vacuum cleaner due to the translational movement of the locking element. Advantageously, the locking element mounted with the possibility of translational movement can be implemented in a particularly simple way. Embodiments of the invention are also possible in which the locking element is mounted, for example, rotatably. This design may be particularly mechanical resistant.

In a further preferred embodiment, a sliding surface is provided on one side of the locking element. The sliding surface can be implemented, for example, in the form of a bevel. Using the sliding surface, it is possible to provide the possibility of installing a dust collector without using a control element. Advantageously, when installing the dust collector in the vacuum cleaner, the sliding surface allows for the displacement, for example, the sliding of the locking element. The sliding surface is located on the fixing element so that the elastically deformable element when installing the dust collector in the vacuum cleaner counteracts the displacement of the fixing element. This design will make it easier to fix when installing the dust collector.

In a further preferred embodiment of the invention, the sliding surface is located on that side of the fixing element that faces the vacuum cleaner during the installation process. Due to this, the fixing element can be displaced during the installation of the dust collector, and upon completion of the installation process, this element will return to the fixing position and fix the dust collector. Advantageously, the sliding surface during installation comes into contact with the vacuum cleaner, as a result of which the locking element can be shifted back.

The present invention constructively simple and inexpensive means allows you to create a vacuum cleaner, dust collector which is securely fixed to the vacuum cleaner during operation of the vacuum cleaner and can be removed from the vacuum cleaner using a simple operation. In particular, the actuating element opening the fixing connection can also be used as a handle for carrying the dust collector, whereby the handling of the vacuum cleaner can be simplified. In addition, the dust collector can be installed in the vacuum cleaner regardless of the position of the handle, so that improper handling of the household appliance can be eliminated.

The implementation of the invention

In the following description of a preferred embodiment of the invention, the same designations refer to the same or comparable components.

An embodiment is described below based on figures 1-7. The figure 1 shows a vacuum cleaner 10 with a node 11, consisting of an engine and a blower device and designed to create a flow of intake air. The vacuum cleaner 10 comprises a dust collector 20, not shown in FIG. 1, for simplification of the image, and a chamber 12 for installing the dust collector 20. FIG. 2 shows a perspective section of the dust collector 20 of the vacuum cleaner 10 shown in FIG. 1. FIG. 3 shows a perspective section of a fragment of the dust collector 20 ( fragment A from figure 2). Figure 4 shows a dust collector according to figures 2 and 3, a top view. Figure 5 shows a perspective section of a dust collector 20 of a vacuum cleaner 10. Figure 6 shows a perspective section of a fragment of a dust collector 20 (fragment B from figure 5). Figure 7 shows a dust collector 20 according to figures 5 and 6, a perspective view.

The dust collector 20 contains two locking devices 40, which are located on opposite sides of the dust collector 20. The locking devices 40 are used to create a detachable locking connection of the dust collector 20 with the vacuum cleaner 10. To control the locking devices 40, the dust collector 20 contains a control element 21, which is made in the form of a handle for removing the dust collector 20. The control 21 allows the user to remove the dust collector 20 from the vacuum cleaner 10. The control 21 is rotatably mounted and can be rotated I am between the holding position and the extraction position. In this case, the holding position of the control element 21 is shown in figures 2-4. The extraction position of the control body 21 is shown in figures 5-7. The dust collector 20 includes a recess 22, which includes the control body 21 in the holding position. When the control element 21 is complex, that is, is in the holding position, the control element 21 is located in the recess 22, so that interfering elements do not protrude from the vacuum cleaner and an attractive appearance of the vacuum cleaner is provided.

To transfer the rotation of the control element 21 to both locking devices 40, the dust collector 20 contains two transmission elements 30. The transmission elements 30, when the control 21 is rotated from the holding position to the extraction position, the locking devices are actuated, as a result of which the locking devices 40 open the fixing connection of the dust collector 20 and a vacuum cleaner 10, and the dust collector 20 can be removed for the control element 21 from the vacuum cleaner 10.

The transmission element 30 is made in the form of a wedge mechanism, that is, a transmission mechanism. The wedge mechanism is easy to manufacture and is particularly durable. At both ends of the control body 21 there is a leash 31, which engages with a wedge mechanism and abuts against the grip surface 32 of the transmission element 30.

The locking device 40 includes a locking element 42 for fixing the dust collector 20 to the vacuum cleaner 10. For this, the locking element 42 in the locking position of the locking device 40 enters the corresponding hole 43 of the vacuum cleaner 10. The locking element 42 is biased so that it can be translated into the positions shown in figures 3 and 5 and corresponding to the locking and unlocking position of the locking device. The locking device 40 includes an elastically deformable element 41, by which the locking element 42 is translated into the locking position, as shown in figure 3. The locking element 42 is automatically translated into the locking position by means of an elastically deformable element 41. On the side of the fixing element 42, which faces to the vacuum cleaner 10 during the installation process, there is a sliding surface 44. When the control 21 is folded, that is, in the holding position, when the dust collector 20 is installed in the vacuum cleaner 10, the locking element 42 of the locking device 40 is pressed into the locking device 40 due to the pressure of the sliding surface 44 on the edge of the hole 43 of the vacuum cleaner 10. As soon as the dust collector 20 is completely inserted into the vacuum cleaner 10, the locking device 40 is fixed by returning the locking element 42 by an elastically deformable element 41 into the hole 43 of the vacuum cleaner 10, that is, into the locking position.

The present invention constructively simple and inexpensive means allows you to create a vacuum cleaner, dust collector which is securely fixed to the vacuum cleaner during operation of the vacuum cleaner and can be removed from the vacuum cleaner using a simple operation. In particular, the actuating element opening the fixing connection can also be used as a handle for carrying the dust collector, whereby the handling of the vacuum cleaner can be simplified. In addition, the dust collector can be installed in the vacuum cleaner regardless of the position of the handle, so that improper handling of the household appliance can be eliminated.

The features stated in the above description, claims and in the figures can be used to implement various embodiments of the invention both individually and in arbitrary combinations.
