Description

Technical field

The present invention relates to a vacuum cleaner with a housing and a removable dust collector, which contains a lid and a lid lock, and in the installed position is in the vacuum cleaner, and the lid lock can be translated into the first and second position, and the lid in the first position of the lid lock is fixed on the dust collector, and in the second position of the lid lock can be removed from the dust collector, and the vacuum cleaner contains a stopper designed to fix the lid lock in the first position.

State of the art

For example, German patent application DE 103 50718 A1 describes a filter for a vacuum cleaner, which is removably mounted in a dust collector chamber located in the main body of the vacuum cleaner. In the known filter of the vacuum cleaner, a pair of guide protrusions are provided, which are located at least on the lid and / or filter housing. These protrusions serve as guides for the filter, which ensure its proper installation in the dust chamber. The user can install the filter in the chamber of the dust collector of the vacuum cleaner using the handle of the lid. The guide lips of the cover slide down along the guide recesses formed on the inner surface of the dust chamber, whereby the filter is installed inside the dust chamber in a suitable place.

In addition, in patent application GB 2453995 A (UK) describes a cleaning device in which the filter can be removed through the side of the device. For this, access to the filter is realized through the hinged door of the device containing the disk. In the side of the device there is a door that is hinged to the main part of the device. The door contains a disk and a mounting device. In addition, the known cleaning device comprises a collection tank. To empty the collection tank, the user disconnects the cyclone separator from the main part of the cleaning device by pressing the unlock button, and removes the cyclone separator. After that, the user presses another unlock button, opening the locking connection. In this way, you can empty the collection tank in which dirt and dust have accumulated.

In addition, European patent application EP 1938735 A2 describes a vacuum cleaner with a dust collector. The dust collector is detachably connected to the vacuum cleaner and comprises a locking element which is fixedly connected to the surface of the dust collector lid on one side and protrudes from the lid on the other side and is biasedly mounted. When the dust collector is fully inserted into the corresponding part of the vacuum cleaner, the free end of the locking element is introduced into it elastically and blocks the dust collector using the groove provided in the vacuum cleaner body. To remove the dust bag, the user pushes the free tip down and pulls the dust bag by its handle.

In European patent application EP 1728460 A1, a device is described for fixing and disconnecting a receiving container with a cyclone element. The device comprises a handle-bracket, a locking / unlocking element and a locking element. A locking / unlocking element locks and unlocks the handle. In the first position, the connection between the cyclone element and the dust container is closed. In the first position, the handle is locked by a locking / unlocking element. In this case, the cyclone element and the dust container are rigidly interconnected. If the handle is in the second position, the cyclone element and the dust container can be separated. The locking / unlocking element comprises a button and an elastic element and is located on the handle of the dust container.

In addition, bagless vacuum cleaners are known in which the handle of a dust collector is immersed in a recess of the housing. In addition, locking devices are known that lock the lid on the vacuum cleaner dust collector. When this latch or actuator is actuated, the cover may be detached from the dust collector. If the dust collector is located in the vacuum cleaner, the housing cover is located above the dust collector, which, accordingly, is not visible from the outside.

Disclosure of invention

The objective of the invention is to provide a vacuum cleaner that compares favorably with the prior art. In particular, improper handling of the lock of the vacuum cleaner dust cover should be avoided. In addition, it is necessary to ensure an attractive appearance of the dust collector and the absence of interfering protruding elements.

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. A dust collector is a device in which intake air containing dirt can be freed from dirt. For example, a dust collector may comprise a filter bag with or without a basket or a centrifugal separator. With proper use, the collected dust collector is installed in a vacuum cleaner. For example, to dispose of dust and dirt accumulated in the dust collector, the dust collector can be removed from the vacuum cleaner. Advantageously, for emptying, the cover can be removed from the removed dust collector.

An advantage of the vacuum cleaner made according to the invention may be the inability to actuate the lock of the dust collector cover in the mounted position, and thus the ability to prevent the cover from being disconnected from the dust collector. According to the invention, this result is achieved due to the presence of a stopper that does not allow the lid lock to be moved to the second position. Thus, the lock can only be in the first position in which it locks the lid on the dust collector. Advantageously, due to the presence of a limiter, the number of positions that the lid lock can occupy when the dust collector is installed can be limited by the first position. In this case, the limiter blocks the movement of the lid lock from the first position to the second position. This can be achieved, for example, due to the fact that the lid lock when moving from the first position to the second position abuts against the stop before it reaches the second position.

Advantageously, the invention eliminates erroneous operation, for example, inadvertently disconnecting the cover from the dust collector when the cover lock is actuated during the suction process. As a result, incorrect operation of the vacuum cleaner can be eliminated, for example, loss of suction power due to the presence of additional unintended openings.

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 of the invention, at least a portion of the lid lock with the dust collector installed is open. When at least a part of the lid lock is open, then at least a part of the lid lock is accessible to the user of the vacuum cleaner during proper operation of the vacuum cleaner. Thus, the openly located portion of the lid lock can be seen from the outside. As a result, the design of the vacuum cleaner can be simplified and cheapened.

In a further preferred embodiment, the lid lock comprises a control. In a particularly preferred embodiment, at least a portion of the control when the dust collector is installed is located openly. Advantageously, the lid lock can be operated by means of a control element, for example, due to the fact that the vacuum cleaner user can move the lid lock by means of the control element from the first position to the second position (so that the lid can be lifted) and from the second position to the first position (so that you can fix the lid on the dust collector). In order to exclude improper handling and, thereby, accidentally unlocking the lid, the control element, advantageously, cannot be activated when the dust collector is installed. In a particularly preferred embodiment, the control element comprises a control surface which makes it easy to actuate the lid lock. The user can, for example, actuate the lid lock by pressing a finger on a control surface.

In a further preferred embodiment of the invention, the control element with the dust collector installed is at least partially flush with the surface of the housing. In a particularly preferred embodiment, the part of the control that is flush with the surface of the housing is open. In this case, in an advantageous way, the control is placed in the housing in such a way as to prevent it from being actuated and thereby unlocking the lid. This can be realized, for example, by selecting suitable distances from the control to the housing. Due to the fact that the openly located part of the control body adjoins the surface of the housing flush with it, that is, is located at the same level with the housing, it is possible to give the vacuum cleaner an attractive appearance.

In one embodiment of the invention, a limiter is mounted on the housing. In a particularly preferred embodiment, the limiter is part of the housing. As a result, in an advantageous manner, the limiter functions can be performed by the housing. Due to this, it is possible to reduce the number of parts in the vacuum cleaner, which reduces its cost. Thanks to the limiter located on the housing with the dust collector installed, it is possible to provide mechanically reliable blocking of the movement of the cover lock from the first position to the second position. The design of the limiter in the form of a part of the housing can be implemented in an advantageous manner by selecting suitable distances between the housing and the cover lock.

According to the invention, preferably, the dust collector comprises a handle. The presence of a handle makes it easy to handle the dust collector after removal from the vacuum cleaner, for example, in order to facilitate the removal of dirt accumulated in the dust collector.

In a preferred embodiment of the invention, the housing comprises a recess in which, when a dust collector is installed, a handle is included. Advantageously, by inserting the handle into the recess, the position of the dust collector in the vacuum cleaner body can be fixed. As a result, the dust collector installed in the vacuum cleaner can only be in the proper position, in which the holes of the dust collector coincide with the corresponding holes of the vacuum cleaner. In addition, the presence of a recess in the housing makes it easier to introduce a dust collector into the housing. At the same time, the introduction of the handle into the recess makes it possible to facilitate both visual orientation and the installation itself. In addition, by immersing the handle in the recess, you can give the dust collector an attractive appearance, ensuring that there are no interfering protruding parts. Preferably, the stopper is part of a recess under the handle.

In a further preferred embodiment of the invention, the lid lock is located on the handle. In a particularly preferred embodiment, the lid lock is movably mounted on the handle. In a particularly preferred embodiment, the lid lock comprises a control located on the handle. Thanks to the lid lock located on the handle, an easily implemented stopper can be created, which can, for example, be part of a recess under the handle. In addition, the user can easily operate the lid lock located on the handle in order to empty the dust collector.

In one embodiment of the invention, the lid lock is biased. In a particularly preferred embodiment, the lid lock is pivotally mounted. For this, in an advantageous manner, the lid lock has an axis of rotation. The lid lock mounted with the possibility of displacement, can be easily moved to the first or second position, so that it can be easier to handle the lock. In addition, the movable cover lock can be characterized by high mechanical reliability.

In one embodiment of the invention, the lid lock comprises an elastic element. In a particularly preferred embodiment, the lid lock comprises a spring. Advantageously, the elastic element can translate the lid lock into the first position. This makes it particularly easy to handle the dust collector, since, for example, after emptying the dust collector, the user simply needs to install the lid on the dust collector, and the lid lock will automatically move from the second position to the first position, thereby fixing the lid on the dust collector.

In a preferred embodiment of the invention, the vacuum cleaner contains a receiving device, and the dust collector in the installed position is in the receiving device. In a particularly preferred embodiment, the dust collector in the installed position is at least partially surrounded by a receiving device. As a result, high stability of the dust collector in the installed position can be achieved. In a particularly preferred embodiment, the lid, when the dust collector is in the installed position, is flush with the surface of the housing. As a result, in an advantageous manner, it is possible to give the vacuum cleaner an attractive appearance.

The present invention constructively simple and inexpensive means allows you to create a vacuum cleaner with a dust collector, in which it will be possible to exclude erroneous operation of the lid lock, for example, during the suction process. In addition, control of the lid lock can be facilitated. In addition, you can give the vacuum cleaner an attractive appearance, for example, to ensure the absence of protruding parts.

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 1-4. The figure 1 shows a vacuum cleaner 10 with a housing 11, the surface 12 of the housing 11 and a removable dust collector 20. Figure 2 shows a section of a vacuum cleaner 10, a perspective view. Figure 3 shows a fragment of a vacuum cleaner 10 (fragment A from figure 2). The figure 4 shows a section of a vacuum cleaner. The dust collector 20 comprises a cover 21, a cover lock 23 and a handle 22, and in the installed position is in the vacuum cleaner 10. In figures 1-4, the dust collector 20 is shown in the installed position. In the installed position, the dust collector 20 is located in the receiving device of the vacuum cleaner 10. This ensures a stable position of the dust collector 20 during operation of the vacuum cleaner 10.

The lock 23 of the cover can be translated into the first and second position, and the lock 23 of the cover for reasons of clarity is shown in the figures only in the first position. In the first position, the cover lock 23 secures the cover 21 to the dust collector 20. In the second position of the cover lock 23, the cover 21 can be removed from the dust collector 20 so that, for example, dirt accumulated in the dust collector 20 can be removed.

In the installed position (mounted state) of the dust collector 20, the lid lock 23 is open and thereby is visible to the user. The lid lock 23 comprises a control member 24 for actuating the lid lock 23. When a dust collector 20 is installed, the control body 24 is flush with the surface 12 of the housing 11. As a result, the vacuum cleaner is given a particularly attractive appearance. The control body 24 has a control surface 25 with which the user can particularly easily control the lid lock 23. To do this, the user grasps the handle 22 with his hand and presses the thumb on the control surface 25. As a result, the user moves the lid lock 23 from the first position to the second position and, thus, can remove the lid 21 from the dust collector 20 so that it becomes possible to remove dirt accumulated in the dust collector 20.

In addition, the vacuum cleaner 10 includes a stopper 14, designed to fix the lock 23 of the cover in the first position. When the dust collector 20 is in the installed position, the limiter reduces the number of possible positions of the lid lock 23 to one first position. As a result, it is guaranteed that the cover 21 of the dust collector 20 cannot be accidentally disconnected by actuating the cover lock 23 by the control member 24 during operation of the vacuum cleaner 10.

The housing 11 of the vacuum cleaner 10 includes a recess 13, which serves as a slot for the handle 22 of the dust collector 20, which is in the installed position. Due to the presence of a recess 13 in the housing 11, it is possible to ensure ease of installation of the dust collector 20. In this case, the direction of the handle 22 facilitates both visual orientation and the actual installation. The limiter 14 is part of the recess 13 for the handle and, thus, is located on the housing 11. Thus, the limiter 14 is realized by selecting suitable distances between the control 24 of the lock 23 of the lid and the recess 13 of the housing 11.

The lid lock 23 located on the handle 22 can be rotated, that is, rotatably mounted. Thanks to this, it can be easily controlled. The lid lock 23 contains an elastic element (not shown in the figures for reasons of clarity) that moves the lid lock 23 from a second position to a first position.

The present invention constructively simple and inexpensive means allows you to create a vacuum cleaner with a dust collector, in which it will be possible to exclude erroneous operation of the lid lock, for example, during the suction process. In addition, control of the lid lock can be facilitated. In addition, you can give the vacuum cleaner an attractive appearance, for example, to ensure the absence of protruding parts.

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.
