Definitions
- the invention relates first to an arrangement of a filter, in particular superfine filter, in a vacuum cleaner with an electric motor having a suction side and a blast side, wherein in the case of the ultrafine filter on the blast side a receiving chamber for the superfine filter is provided, and the filter has a filter frame.
- Vacuum cleaners have in a known manner a dust collection bag for the filtration of dust and dirt particles from the dirt-laden suction air stream. It is further known in this regard that the suction air stream cleaned of coarse particles before discharge into the environment is finally passed through a micro-filter, for the retention of very fine particles. Such a fine filter is arranged on the blast side of the electric motor. In addition to the filtering out of the smallest dust particles still present in the blow-off air flow, such a microfilter also optionally serves to filter out carbon particles from the upstream electric motor. Since the recorded in the usual way in a plastic housing of the ultrafine filter paper is added over time with particles, it is also known to interchangeable absorb the particulate filter in the vacuum cleaner.
- the service life of a filter for a vacuum cleaner depends, among other things, on the degree of filling of the filter or on the degree of clogging of the filter material used. Such a filter state is achieved via a pressure-dependent filling degree measurement and displayed to the user. If a predefined differential or negative pressure value is exceeded or undershot, the respective filter must be changed.
- an actuating tab is formed on the filter frame and that the actuating tab resets an operating hours counter at an introduction of the filter in the receiving chamber.
- an arrangement is provided which has an operating hours counter as a filter change indicator, whereby the display of a filter change to be carried out is achieved independently of a degree of filling measurement thereof.
- Such an operating hours counter proves to be particularly advantageous in connection with a superfine filter, since in this case the filling degree determination by means of pressure measurement proves to be unsuitable (inter alia, too costly).
- such an operating hours counter can also be used in conjunction with a conventional dust filter bag or the like.
- the filter frame may in this case be a plastic frame comprising the filter material, in particular in the case of a micro-filter.
- the filter frame may be formed by a holding plate holding the dust filter bag in the corresponding receiving chamber.
- the operating hours counter is used to record the service life of the monitored filter.
- a predetermined time value is exceeded, the user is displayed the necessary filter change via an acoustic and / or visual signal. Preference is given further lent that resetting the hourmeter to a null position can only be accomplished by inserting a filter with a filter frame having a corresponding tab.
- a switching element is further preferably provided, which is to be actuated only by a non-offset actuating tab.
- the operating hours counter is not to be put into its zero position by a filter already used once. This is only possible by a new, provided with a non-offset actuating tab filter. Accordingly, it is ensured that the reset of the operating hours counter is achieved by a new, unused filter.
- the switching element can act on an electric switch whose switching state is detected by an electronic system or the like. About this electronics is the timing of the operating hours counter and also its reset to the zero position. In addition, the electronics can also be used to acoustically and / or visually display the condition of the filter.
- the switching element moves the electric switch either in a switched or in a non-switched position at each passage of the non-offset operating tab.
- the downstream electronics monitor the position of the electrical switch.
- the operating hours counter is reset with each switching movement of the electric switch from a switched position to a non-switched position and vice versa. Accordingly, the position change of the electric switch is detected by the downstream electronics, which leads to a reset of the operating hours counter to the zero position.
- the operating hours counter continues to run, so according to a reinserting an already used and provided with a correspondingly in a non-actuation position permanently pivoted actuating tab filter.
- the switching element can also interact as an offset stop with the actuating lug.
- the non-offset actuating tab overflows the switching element. Only a removal of the filter from the receiving chamber leads under stops on the switching element to a permanent pivoting of the actuating tab in the non-actuated position. Further alternatively, it is suggested that the
- the electric switch holds the electric switch only in the course of passage of the unequipped operating tab in a switching position.
- the electric switch is designed as a button, wherein in a switching operation by the acted upon via the actuating flap switching element, a pulse of the short-term closing in the course of passage of the non-offset actuating tab button is detected.
- the switching element may be a ratchet, which is further rotated by a non-offset actuating tab by one segment.
- the switching element may also be a rocker, which is urged over the non-offset actuating tab from a preferably spring-loaded basic position in an actuating position acting on the electrical switch.
- the invention further relates to a fine filter to be arranged in the exhaust air flow of a vacuum cleaner, in particular a household vacuum cleaner with a cassette-like plastic housing.
- a micro-filter of the type in question nutzsvorteilhafter it is proposed that on the plastic housing an actuating tab is formed, which is displaceable from an operating position to a non-actuated position.
- a superfine filter is created, which can recognize the basis of the position of the plastic housing formed on the actuating tab, whether it is unused or has already been used at least once.
- the actuating tab forms an indicator.
- the actuating tab may in this case be in cooperation with the accommodating the micro-filter receiving chamber of the vacuum cleaner, so on, for example, with a contact which can only be actuated via an operating tab located in the operating position. For example, this contact for commissioning the vacuum cleaner can be forcibly closed. Accordingly, it is ensured that the vacuum cleaner can be switched on only in the operating position befindaji flap position of the ultrafine filter; Consequently, it can not be operated without the finest filter.
- the actuating tab is preferably a filter change indicator for the micro-filter.
- the operating tab is used to reset an operating hours counter.
- Such hour meter provides a filter change indicator that operates independently of a Gression. It is essential that the actuating tab acts only in the operating position on the operating hours counter with respect to a provision in a zero position. If the actuating tab is placed in a non-actuated position, then the insertion and removal of the filter into or out of the vacuum cleaner has no effect. Accordingly, the operating hours counter continues to operate when the vacuum cleaner is started up.
- the Actuation tab is preferably formed of plastic, so on material of the same with the plastic housing of the ultrafine filter.
