Definitions
- the invention initially relates to an arrangement for detecting a filter element used in an electric vacuum cleaner as new and designed in a certain way.
- the operating state of the electric vacuum cleaner is controlled by this arrangement determines whether a proper filter is provided, in addition, if appropriate, whether this is used correctly and further, if necessary, whether this is new.
- the filter element with a removable from an area of action element so as to detect the correct insertion of a suitable filter element for operation by optical and / or mechanical means. After initial insertion, for example, a device-side switch or the like influencing element is spent in a non-operative position, so that a re-insertion of a used filter element leads to a corresponding device-side detection.
- a detection of a filter element used in an electric vacuum cleaner is achieved as new and formed in a certain way by electrical means.
- the filter element is at least initially part of the electrical circuit, correspondingly preferably closing a circuit that serves to detect the filter element.
- the filter element acts in this situation in a figurative sense as a switch.
- a device-side usage counter is set to zero according to one embodiment.
- the degree of filling can not or only partially be detected, such utility meter are beneficial.
- the user is displayed, for example via an optical display of the necessary change of the filter element.
- the use of a new filter element to be performed hereafter requires resetting the utility meter.
- the use of a utility meter can also be provided in connection with a filter bag for receiving the fauxschaugenden coarse dirt, then even with such a configuration, the use of a new dust filter bag has the provision of the utility meter to zero result.
- the use of an already used filter element leaves the usage counter unaffected.
- an error message can be triggered as soon as the same filter element is reused in the receiving housing for further use, depending on an opening of the housing. Accordingly, after opening the housing receiving the filter element, insertion of a new filter element having the corresponding part of an electrical circuit is required.
- the filter element loses after insertion into the vacuum cleaner and preferably according to hereafter Roumalem first Turning on the vacuum cleaner its function as part of the electrical circuit, with the result that this filter element is not re-detected when reusing.
- the type of filter element may also be detectable, for example as a function of predetermined resistance values within the looped-in subcircuit.
- the filter element has an electrically conductive element, which loses its conductivity at startup of the vacuum cleaner, in the remaining part firmly trained circuit, and proper energization of the circuit in the manner of an electrical fuse. It may in this regard be an electrical or electronic component, which leads by closing the new filter element in the vacuum cleaner for closing the detection serving electrical circuit.
- the provided outside the filter element subcircuit is an integral part of the vacuum cleaner and is in electronic contact with an electronics, for example, sets the utility counter to zero and / or triggers an error message on further use of the same filter element. This provided on or in the filter element electrically conductive element leads to a brief closure of the detection circuit.
- the conductivity of the filter element-side element is canceled.
- the circuit is interrupted thereafter. Accordingly, the insertion of a new filter element merely results in a pulse-like switching due to the circuit closure by means of the filter element. That sets the usage counter to zero and prevents an error message.
- the electrical element of the new filter is influenced immediately after its detection so that the circuit is interrupted again.
- a mechanical element can be displaced so that the filter-side element is destroyed, for example, separated.
- a particularly her position favorable solution is achieved in that the conductive element is electrically separated by melting. Accordingly, the conductive element is designed so that this when intended energization as a result of a first switching on the
- Vacuum cleaner in the shortest possible time preferably burned within a part of a second.
- the short-term conductivity before melting is sufficient as a pulse for a device-side electronics for resetting the utility counter to zero or to prevent an error message.
- the invention further relates to a filter element to be used in an electric vacuum cleaner, for example a filter bag or a box-type superfine filter.
- an electrically conductive element is proposed, which can be part of an electrical circuit resulting from the addition of dust-proof components when the filter element is inserted into the vacuum cleaner, wherein the electrically conductive element is included Proper energization in the form of a fuse in a non-conductive state passes.
- a reuse of a used filter element can optionally be prevented by means of such a filter element in connection with a suitably designed vacuum cleaner, so on, at least in the form of an error message displayable.
- a utility counter or the like can be set to zero, if a new Filter was used.
- the electrically conductive element having filter element in the vacuum cleaner and subsequent initial switching of the same loses the electrically conductive element of the filter in accordance with the intended energization of the overall circuit its conductivity, after which the filter is already used as already inserted and integrated into the circuit.
- Figure 1 is a perspective view of an electric vacuum cleaner with filter elements.
- FIG. 2 shows the filter element in the form of a filter bag in a perspective view
- FIG. 3 is a detail sectional view through the edge region of a filter bag holder plate side carrying cassette and a conductive element of the filter bag holding plate scanning, device-side contact lug;
- Fig. 5 shows an exemplary electrical circuit for detecting the filter element
- Fig. 6 shows the filter element in a second embodiment, in the manner of a box-like ultrafine filter.
- an electric vacuum cleaner 1 in the form of a handheld vacuum cleaner is shown and described with a base housing 2, a filter chamber 4 accommodating this at a pivotable position, a filter bag 3 forming a first filter element E, and a device handle 5 and a vacuum cleaner. Attachment 6.
- the filter bag 3 has a holding plate 7, with an opening 8 through which dirt / dust particles are transported into the filter bag 3 by means of the suction air flow to be applied.
- the filter bag 3 is supported on an associated end edge 11 of the filter chamber 4 with clamping inclusion of the holding plate edge 10 by a peripheral edge 12 of the base housing 2 corresponding to the end edge 11 of the filter chamber.
- an electrically conductive element 13 is provided on the underside, in the installation situation corresponding to the end edge 11 of the filter chamber 4 facing. This is the entire surface connected to the holding plate material, for example glued to this and formed in the simplest manner in the form of an electrical conductor, with two free ends.
- the electrical element 13 is destroyed, as a result of melting of the conductor as a result of intended energization of the entire circuit.
- the conductor is provided for this purpose with a correspondingly low thickness or width.
- the melting point can be predefined, for example by a waist-like constriction and / or by contact-free exposure of a conductor track section.
- galvanic isolation causes the potential VA to be measured on the info line.
- the circuit S After reaching a maximum operating hours and / or in the course of opening the filter element E receiving housing, the circuit S is placed in a state in which a monitoring of the filter element circuit takes place. If a used filter element E with a destroyed electrical element is reused in this state, this does not correspondingly lead to a detection of the voltage VB.
- FIG. 5 shows the filter element E in the form of a superfine filter 16. This has a box-like housing 17 in which filter material 18 is inserted in a zig-zag shape.
- the electrical element 13 On a side surface of the housing 17, the electrical element 13 is externally provided in the form of a serpentine applied conductor track, with end contact points 19 which are in use position with device-side tabs in electrical connection.
- This electrical element 13 is also designed in such a way that when current is supplied in the proper manner, that is to say in the case of a customary energization suitable for the circuit S, it melts and thus loses its electrical conductivity.
