Definitions
- the invention relates to a suction nozzle for a vacuum cleaner, which is connectable to a suction pipe and / or to a suction hose of the vacuum cleaner, wherein the suction nozzle has a nozzle provided with a suction nozzle, which via a tubular connection part with the suction pipe or with the suction hose of the vacuum cleaner can be connected, with a arranged in the flow path of the vacuum cleaner dust flow sensor whose signals are evaluated by an electronic control device and wherein the control device in operation controls a display the dust flow display device.
- Both proposed solutions have in common that the sensor and display device is arranged in the bottom part of the suction nozzle.
- a removable part housing is provided above the bottom part of the Saugduse to accommodate the sensor and the display elements.
- optical dust detection means are provided in the suction channel or in the suction region of the bottom part of the suction nozzle.
- the bottom nozzle shown in this prior publication makes the disadvantages of this embodiment particularly clear.
- a solution which has become known from EP 0759 157 B1 is particularly advantageous in that it uses a piezoelectric sensor device by means of which even the smallest dust particles can be reliably sensed, while z. B. Carpet fibers do not affect the signal so much.
- the piezoelectric sensor in the intake pipe or in an intake of the vacuum cleaner. When the dust particles present in the flow air path strike the piezoelectric sensor, they release a part of their kinetic energy to the sensor, the piezoelectric sensor converting the kinetic energy into a corresponding electrical signal (piezo voltage).
- the invention thus raises the problem of accommodating a sensor and display device in the flow air path of the vacuum cleaner such that a space-saving and ergonomically favorable attachment of the components involved in the overall system is provided. Furthermore, a flow favorable location for the sensor is to be found, with a trouble-free and reliable functioning operation is guaranteed.
- the bottom part and the suction nozzle of the suction nozzle can be kept flat in its design.
- the design of an attachment housing on the upper side of the connection part or of the ascending connection piece also makes it possible to achieve an ergonomically favorable and design-compatible housing of all components.
- the battery compartment for example, is easily accessible and changing the battery is very easy.
- the display elements representing the state of the suction air in the manner known per se on display LED * s can be clearly visible housed for the user. The user always has this viewing window in direct eye contact because he has the suction nozzle area along the suction tube in the visor while sucking.
- the attachment of the piezoelectric sensor to the underside of the upper wall of the connection part decisively supports the special function of the system. If there are still heavy parts and particles in the suction air stream, they are usually transported below the sensor with the dust air flow in the collection chamber system of the vacuum cleaner. As a result, the sensor is protected and is not constantly exposed to the impact of heavy particles. Plus, he can develop his benefits when it matters. This is usually the case when the dust accumulation and the particle number of the air flow with the progress of the suction operation is getting lower. The sensor can even detect even the smallest dust particles in the air stream, so that it can still provide meaningful information to the user up to a very high degree of purity. This is very important especially for allergy sufferers. For these it is very advantageous that with the er i Dust indicator according to the invention known to be very allergenic particulate matter can be detected.
- Another advantage of the new arrangement is that a holding device is provided to which all the essential components are attached, such as the dust sensor, the board with the controller, the vacuum switch and the display elements.
- a space-saving and compact design can be realized.
- the holding device can be detachably inserted into the opening of the connection part of the suction nozzle.
- the assembly is in the installed state formed so that the air inlet line of the pressure switch is in the lee of the recording device, whereby contamination on the air inlet line are prevented, which would otherwise interfere with the proper operation of the pressure switch.
- FIG. 1 shows a vacuum cleaner with suction nozzle, suction tube and suction hose in a simplified schematic diagram
- FIG. 2 shows the suction nozzle according to the invention in a perspective view in detail
- FIG 3 shows the suction nozzle according to the invention in side view and fragmentary the area of accommodation of the sensor, display and control device in the connecting piece in section,
- Figure 4 shows the tubular part of the connecting piece in section II - II in the direction of the
- Figure 5 shows the connection part of the suction nozzle in a perspective assembly drawing.
- FIG. 1 shows a vacuum cleaner (1) with a suction nozzle (2), a rigid suction pipe (3) and a flexible suction hose (4), via which the dust-laden air is transported in the direction of the arrow into the dust collecting space (5).
- the suction nozzle (2) is usually detachably connected to the suction pipe (3).
- the suction nozzle (2) is in the example shown a floor nozzle and consists essentially of the suction mouthpiece or nozzle part (2.1) and the connecting part (2.2). Nozzle part (2.1) and connecting part (2.2) are usually connected to one another via a shoulder (2.3) mounted, so-called Drehkippgelenk.
- a suction nozzle designed according to the invention is shown in detail in FIG. Again, the nozzle part (2.1) of the suction nozzle (2) via the in the approach (2.3) mounted Drehkippgelenk connected to the connecting piece serving as the connecting part (2.2).
- the Connecting part (2.2) has at its upper end a locking pawl (6), with which the suction nozzle (2) can be attached to the suction pipe (3) of the vacuum cleaner.
- connection part (2.2) On the upper side of the ascending connection part (2.2), on the side facing the nozzle part (2.1) of the suction nozzle (2), the connection part (2.2) is formed with a housing (7).
- Figures 3 and 4 show the connector (2.2) with the control, sensor and display means housed therein in detail.
- the connecting part (2.2) consists of the connecting piece (2.4) which can be connected to the swivel joint (2.3) and the connection piece (2.5), which can be connected to the suction pipe (not shown here).
- the two connection sockets (2.4 u.2.5) merge into one another to form an angle and thus form the connection part (2.2).
- On the lower side of the connecting part (2.2) is still a Rastem elemerrt (18) formed for a parking aid.
- a battery compartment (8) is provided in the lower part.
- a receiving chamber (7.1) for the electrical control device for the detection of dust flow as well as for the dust flow indicating means is formed in the upper part of the housing (7).
- the housing has a viewing window (9) for the dust flow indicator on the end face facing upwards to the connection piece (2.5). This viewing window is thus aligned in the direction of the connection point for the suction pipe (3).
- the display (9) is located in a clearly visible area, since the user constantly has his sights on the display device along the suction tube (3) during suction.
- the battery compartment (8) is provided with a removable cover (8.1), as is common in battery-powered devices. The batteries (13) can thus be easily accessible replaced.
- the piezoelectric dust sensor (11) is fixed in the upper wall of the connecting part (2.2) in a receiving part (12.1) of a holding device (12). In this case, the piezoelectric dust sensor (11) projects obliquely inclined into the dust flow stream in the interior of the tubular connecting part (2.2).
- a negative pressure switch (15) which can be activated by the control device is fastened on the circuit board (14) and communicates with its air inlet line (15.1) via an opening (17) with the dust flow stream.
- the Staubhnean Seaeetic (16) are also mounted on the board (14) and aligned with the viewing window (9), so that the display is displayed to the outside.
- the LED s (16) are arranged on the circuit board (14) with a light radiation-dependent coordinated distance to the viewing window (9), so that in conjunction with the choice of a suitable material for the viewing window results in a planar illumination of the viewing window. Furthermore, it is characteristic that the viewing window is always backlit depending on the detected contamination in only one color (green, yellow, red), on the one hand to indicate the clear suction progress and on the other hand to allow a clear readability of the display in all possible orientations when the suction nozzle is combined with different suction pipes and handle parts of the suction hose of the vacuum cleaner. Furthermore, this constructive solution contributes to a reassurance of the display is achieved and that flicker of the LED x s, due to the strongly fluctuating signals of the dust sensor is largely avoided.
- a closable opening (19) Through the interior of the pipe socket, for. for cleaning or replacing the dust sensor (11) is accessible.
- the dust sensor (11) is exposed with its baffle and the oblique arrangement the upper part of the air flow in the tubular part of the connecting piece.
- This has the particular advantage that the heavy parts in the suction air flow are transported away under this sensor without reaching its baffle surface (see arrow direction in the connection part).
- the light particulate matter, which is distributed per se in the entire cross section of the air flow, is detected by the dust sensor (11).
- a degree of purity can be sensed with this sensor technology and this special arrangement of the sensor, in which even the finest dust can be taken into account, which benefits the allergy sufferers among the users.
- the dust sensor (11) is advantageously arranged with an inclination angle (23) of 25 to 50 degrees in relation to the upper wall of the connecting part (2.2) in the dust air flow.
- the upper housing part is a housing shell (7.2), which is adapted to the shape of the connecting part (2.2) on its upper side.
- the connecting part (2.2) has on its upper side latching and fastening elements (21, 22) by means of which the housing shell (7.2) to the connecting part (2.2) by latching and by screwing can be fastened.
- the holding device (12) takes on its upper side, the board (14). On the board of the vacuum switch (15) and the display elements (16) and the control circuit not shown here in detail are arranged. It may be appropriate to look behind the display elements (16) to arrange a reflector, not shown in this drawing, which reflects the light rays in the direction of the viewing window (9).
- the connection to the batteries (13) is produced, wherein the batteries (13) in the battery compartment (8) can be used.
- the battery compartment can be closed with the battery compartment cover (8.1).
- the arrangement and design of the holding device (12) and the printed circuit board (14) is such that the air inlet line (15.1) of the vacuum switch (15) via the opening (17) formed in the receiving device (12.1), and the neck ( 12.2) in conjunction with the interior of the connecting part (2.2) can be brought.
- the receiving part (12.1) of the holding device for receiving the dust sensor (11) immersed in the attachment of the holding device (12) on the connecting part (2.2) through the opening formed there on the top (20) in the interior of the connecting part (2.2).
- the dust sensor (11) is thus exposed to the dust air flow and the air inlet line (15.1) of the pressure switch (15) lies in the lee of this receiving part (12.1) of the holding device.
- the display elements (16) are designed as green, yellow and red LEDs. In the assembled state, the arrangement is such that the display elements (16) are in a light radiation moderately matched position to the viewing window (9). Together with the selection of a suitable material for the viewing window (9) results in a flat and highly visible, flicker-free display. The user always sees only a full-surface display in the colors red, yellow and green, showing the degrees of purity "dirty”, “slightly dirty” and "clean".
- connection part can also be designed as an independent part or accessory and can then be connected between the suction nozzle (2) of a vacuum cleaner (1) and its suction pipe (3) or its suction hose (4).
- the connecting part is formed in the same way as the connecting part (2.2), except that in addition at its lower end also a connecting element is arranged, which establishes the connection with a connecting piece of the nozzle part (2).
- the sensor and display control communicate via a wireless transmission system with a control center in the vacuum cleaner, which allows further control and display options to be displayed via the suction process.
- the power supply for sensor and display control in the connection part from the power supply system of the floor nozzle in the case of electrical bottom nozzles.
