Definitions
- the invention relates to a method for operating a floor cleaning system with a central suction station, to which a self-driving and self-controlling suction device is assigned, wherein the suction device picks up dirt from a floor surface to be cleaned and transfers it into a dirt collecting container of the suction device, and wherein the suction station has a suction unit and one sucks off the dirt collecting container by means of the suction unit.
- the invention also relates to a floor cleaning system for using the method.
- the suction device is designed to be self-propelled and self-controlling and can pick up dirt from the bottom surface, which is transferred into a dirt collecting container carried by the suction device. If the dirt collection container is full, the suction device automatically controls the central suction station at which the dirt collection container is emptied.
- the suction station comprises a suction unit for suctioning off the dirt collecting container. After extraction, the suction device can resume its suction operation and move along the floor surface to be cleaned.
- the suction of the dirt collection container is associated with a certain amount of noise.
- the object of the present invention is to provide a method of the type mentioned at the beginning, with the aid of which the noise development of the floor cleaning system can be reduced.
- the suction unit is operated either with maximum suction power or with reduced suction power.
- the noise level of the floor cleaning device can be reduced by operating the suction unit with reduced suction power.
- Such a reduced-power mode of operation is particularly advantageous when the floor cleaning system is used at night. If the floor cleaning system is used at times when the noise is perceived as particularly annoying, the user can choose the mode of operation with reduced suction power of the suction unit. This enables considerable noise reduction, for example a noise reduction of at least 5 dB (A) compared to the noise development of the suction unit with maximum suction power.
- the suction unit is preferably operated for a predetermined period of time with reduced suction power and then again with maximum suction power. This ensures that after a predetermined period of time, the dirt collecting container is again acted upon by the suction flow which forms at maximum suction power of the suction unit, so that it is again at the latest after the predetermined period of time is completely emptied and practically no residual dirt remains in the dirt collecting container.
- Such a procedure is particularly favorable if coarse-grained dirt particles accumulate in the dirt collecting container during the reduced-power operation of the suction unit.
- the suction unit is operated for a maximum of about eight hours with reduced suction power and then again with maximum suction power.
- the dirt collecting container is preferably suctioned off at least once with the maximum suction power of the suction unit after the time period specified for the operating mode with reduced suction power. After vacuuming the dirt collecting container with maximum output, you can then switch back to the reduced output mode. It has been shown that a single suction process with maximum suction power is sufficient to completely remove coarse-grained dirt particles from the dirt collecting container.
- the mobile suction device can usually be switched on and off independently of the central suction station. If the floor cleaning system is in its reduced-power mode of operation and the mobile suction device is switched off in this state, the case may occur that the user simultaneously enters the command for the mode of operation with reduced suction power when the suction device is switched on again. There is therefore a risk that the operating mode with reduced suction power will extend over a very long period of time and that it will Collect an impermissibly large amount of coarse-grained dirt particles. In order to counteract this danger, it is advantageous to measure the time between two aspirations of the dirt collecting container during operation with reduced suction power and to compare it with a maximum permissible time and, if the maximum permissible time is exceeded, to switch to operation with maximum suction power.
- the suction device is suctioned off with reduced suction power of the suction unit and switched off in this state and it is switched on again at a later point in time, with the reduced-power operation of the suction unit being selected again, the time span between the last suctioning of the dirt collecting container is exceeded if a predetermined maximum value is exceeded and the current suction, regardless of the mode of operation selected by the user, switches to operation with maximum suction power in order to completely empty the dirt collecting container.
- the mode of operation with maximum suction power can be limited in time, in particular it can be provided that in this case the dirt collecting container is suctioned off only once with maximum suction power and that one then goes back to the mode of operation selected by the user with power-reduced suction power.
- a command to restart this operating mode is suppressed during the operating mode with reduced suction power. This prevents the user from extending the maximum time period provided for the reduced-power mode of operation by restarting this mode of operation even before the suction station has automatically switched from the reduced-power mode of operation to the mode of operation with maximum suction power.
- the mode of operation with reduced suction power can, for example, be such that the suction station is operated at a maximum of 50% of the electrical power that the suction station has at maximum suction power. For example, it can be provided that the suction station consumes an electrical power of 600 W at maximum suction power, while the power consumption of the suction station is only 250 W at reduced suction power.
- the present invention also relates to a floor cleaning system using the aforementioned method.
- the floor cleaning system here comprises a central suction station to which a self-driving and self-controlling suction device is assigned, the suction device having a dirt collecting container and a suction turbine for picking up dirt from a floor surface to be cleaned and for transferring the dirt into the dirt collecting container, and wherein the suction station is a suction unit has for suction of the dirt collecting container.
- the suction unit can be operated either with maximum suction power or with reduced suction power.
- the suction station has an activation element which can be actuated by the user, for example a selector switch or pushbutton element, for activating the operating mode with reduced suction power.
- an activation element which can be actuated by the user, for example a selector switch or pushbutton element, for activating the operating mode with reduced suction power.
- the suction unit can be operated for a predetermined period of time with reduced suction power and, after the predetermined period of time has passed, it switches to an operating mode with maximum suction power.
- a design of the floor cleaning system has the advantage that the user does not have to take care of himself that the dirt container is vacuumed from time to time with the maximum suction power of the suction unit, rather the suction unit goes after a predetermined period of time, for example after the expiration of about eight hours, regardless of a corresponding control command from the user into the mode of operation with maximum suction power. If the user wishes to select the reduced-power mode of operation of the suction unit again, it can be provided that for this purpose he has to actuate the activation element again.
- the suction station comprises an activation element for activating the operating mode with reduced suction power, the predetermined time period for the operating mode with reduced suction power not being extendable by repeated actuation of the activation element. This prevents an actuation of the activation element during the reduced-power mode of operation of the suction station leading to an extension of this mode of operation. Instead, the reduced-power mode of operation can only be started during the mode of operation with maximum suction power are, that is, the activation element is effective only at maximum suction power of the suction unit.
- Such a configuration ensures that the user cannot reset the timer with which the duration of the mode of operation with reduced suction power is actuated by actuating the activation element, in order in this way to operate the suction unit permanently with reduced suction power.
- an activation signal which is provided by the activation element of a control of the suction station, is consequently suppressed.
- Such an activation signal is rather effective in such an embodiment of the floor cleaning system only during operation with maximum suction power of the suction unit.
- the suction unit can only be operated again with reduced suction power after operation with reduced suction power after at least one suction of the dirt collecting container with maximum suction power.
- the suction station comprises a test device, with the aid of which it can be checked whether, after a predetermined period of time, the Operation with reduced suction power at least once the dirt collecting container was sucked off with maximum suction power. A renewed transition to the operating mode with reduced suction power is only released by the test device if a suction with maximum suction power has previously been carried out.
- the suction station automatically switches to the mode of operation with maximum suction power, provided that the time period between two suctionings of the dirt collecting container exceeds a predetermined maximum value.
- the suction station has a timer that measures the time between two suctionings of the dirt collecting container, the timer being associated with a test device that compares the measured time with a predetermined maximum time and, if the maximum predetermined time is exceeded, the reduced power Operation of the suction unit ended. The timer is started each time the suction of the dirt collecting container begins and is read out by the test device at the start of the subsequent suction, so that the determined value can be compared with a predetermined maximum value.
- the suction power of the suction unit is at least about 50% of the maximum suction power can be reduced.
- the suction station can be significantly reduced in noise.
- Figure 1 is a schematic side view of a floor cleaning system according to the invention with a mobile suction device docked to a central suction station;
- Figure 2 is a schematic longitudinal sectional view of the floor cleaning system according to Figure 1 and
- Figure 3 a flow chart for the operation of the floor cleaning system.
- FIG. 1 and 2 schematically show a floor cleaning system according to the invention, generally designated by reference number 10, which comprises a self-propelled and self-controlling suction device 12 and a central suction station 14.
- the mobile suction device 12 comprises a housing 16 with a top wall 18 and a bottom wall 20, which define a suction channel 22 between them.
- a cover 24, not shown in FIG. 2, is placed on the ceiling wall 18 in order to achieve a better overview.
- the housing 16 forms a chassis of the mobile suction device 12.
- On the housing 16 are in itself Known and therefore not shown in detail in the drawing, two drive wheels 26 rotatably mounted, each having an electric drive motor (not shown) known per se.
- the drive motors are controlled by means of an electronic control 28 which is known per se and is therefore only shown schematically in FIG. 2 and which is connected to the drive motors via control lines not shown in the drawing.
- the bottom wall 20 has a suction inlet 30 through which sweeping brushes 32 of a brush roller 34 rotatably mounted above the suction inlet 30 pass.
- the brush roller 34 is rotatably drivable by means of an electric motor 36 which sits above the brush roller 34 on the top wall 18 and is coupled to the brush roller 34 by means of transmission means known per se and therefore not shown in the drawing.
- the housing 16 In its rear area facing away from the charging station 14, the housing 16 carries a suction turbine 40 which can be driven in rotation by an electric drive motor 42 and is in flow connection with the suction channel 22 via an intake port 44.
- the electrical consumers of the mobile suction device 12 are supplied with energy by means of a rechargeable battery 46 which is carried by the ceiling wall 18 and is shown in FIG.
- a dirt filter 48 is arranged within the suction channel 22 obliquely to the longitudinal extent of the suction channel 22, and the area of the suction channel 22 between the dirt filter 48 and the suction inlet 30 forms a dirt collecting container 50, the fill level of which is monitored by a fill level sensor 52 which is in electrical connection with the controller 28.
- the dirt filter 48 has a frame 49 on which a filter fabric 51 is supported in a self-supporting manner, the filter fabric forming a curvature with respect to the frame 49 even in the unloaded state.
- the filter fabric aligns itself in accordance with the air flow prevailing in the suction duct 22. A reversal of the air flow causes a reversal of the direction of the curvature of the filter fabric 51 and thus a filter cleaning that is simple to construct and effective.
- the suction turbine 40 For cleaning a floor surface, the suction turbine 40 generates a suction flow, with the aid of which dirt can be transferred from the floor surface to be cleaned through the suction inlet 30 into the dirt collecting container 50.
- the dirt pick-up from the floor surface is supported by the brush roller 34.
- the suction device 12 automatically travels along the floor surface to be cleaned until the state of charge of the battery 46 monitored by the controller 28 approaches a minimum value or until the fill level sensor 52 detects that the dirt collecting container 50 is full. If at least one of these two conditions is met, the suction device 12 automatically controls the suction station 14, at which the battery 46 can be charged and the dirt collecting container 50 can be emptied at the same time.
- the suction station 14 has a housing 54 which has an suction unit 56 driven by an electric motor and a dirt holding container 58 surrounds that can be acted upon by the suction unit 56 with a negative pressure.
- a bracket 60 is held laterally on the housing 54 of the suction station 14, which surrounds a control chamber 61 and has an end wall 62 at its end facing away from the housing 24, which is connected to the housing 54 via a cover 64 and a support plate 66.
- a ramp 74 is formed on the housing 54, which has a suction opening 76.
- the latter is connected to the dirt receptacle 58 via a suction channel 78.
- the area between the boom 60 and the ramp 74 defines a docking point 80 for the suction device 12 and is delimited in the direction of the housing 54 of the suction station 14 by a support wall 81, on which two electrical contact elements 82, 84 are held.
- the suction station comprises a charger known per se and therefore not shown in the drawing, which can be connected to a mains voltage and is connected to the electrical contact elements 80 and 84 via supply lines not shown in the drawing.
- Associated with the electrical contact elements 82 and 84 of the suction station 14 are held on the outside of the cover 24 of the suction device 12 two electrical contact pins 86, 88, shown schematically in FIG. 1, which are connected to the rechargeable battery 46 via connecting lines (not shown in the drawing) stand. Via the electrical contact elements 82, 84 and the associated contact pins 86 and 88, electrical energy can be transmitted from the suction station 14 to the suction device 12 for charging the battery 46.
- the suction device 12 When docking with the suction station 14, the suction device 12 assumes such a position on the ramp 74 that the suction inlet 30 is aligned with the suction opening 76.
- the suction unit 56 is then activated by an electronic control 90 of the suction station 14 arranged in the control room 61, which detects the flow of a charging current via the contact elements 82, 84, so that the dirt collecting container 50 is formed by forming a suction flow symbolized by the arrows 92 in FIG. 2 can be suctioned off via the suction inlet 30 and the suction channel 78 and dirt can be transferred into the dirt holding container 58.
- the battery 76 of the suction device 12 is recharged.
- the operation of the suction unit 56 is associated with a noise development of the suction station 40.
- the user can activate an operating mode of the suction unit 56 with reduced suction power by actuating an electrical pushbutton element 94 arranged on the cover 64 of the arm 60.
- the controller 90 which includes a test device 91 and is coupled to an electronic timer 96, checks whether the prerequisites for suction with reduced suction power are present, or whether, despite actuation of the pushbutton element 94, suction of the dirt collecting container 50 with maximum suction power of the Suction unit 56 is to be performed. To this end, the controller 90 executes the following method steps, which are explained in more detail in FIG. 3: According to the symbol 100 shown in FIG.
- the docking of the suction device 12 to the suction station 14 and the associated flow of a charging current via the contact elements 82 and 84 is first checked by the test device 91 in method step 102 as to whether the user has entered the command for activating the reduced-power suction operation by actuating the feeler element 94 , If this is not the case, then in method step 105 the dirt collecting container 50 is suctioned off with the maximum suction power of the suction unit 56. In this case, the suction unit 56 can be activated, for example, for about 20 to 40 seconds. This period is sufficient to completely empty the dirt collecting container 50.
- step 103 the control unit 90 queries the timer 56, which has been the time span since the last Docking process of the control unit 12 measures.
- step 103 the test device 91 then compares the detected time period with a predetermined maximum value, which can be, for example, two hours. If the test in method step 103 shows that a longer time than the maximum permissible time has elapsed since the last docking process, the method of operation 104 is ended with reduced suction power and suction of the dirt collecting container 50 is carried out in accordance with method step 105, i. H. with maximum suction power.
- the dirt collecting container 50 is suctioned off with reduced suction power of the suction unit 56.
- the suction unit is preferably active for 20 seconds to 40 seconds.
- a further value of the timing element 96 is queried by the testing device 91, namely the period of time that has elapsed since the start of the reduced-power mode of operation. If this check shows that the operating mode with reduced suction power has been present for more than eight hours, then the operating mode with reduced suction power is ended in method step 110. If, instead, the test reveals that the maximum predetermined period of time, for example eight hours, has not yet been exceeded, the operating mode is maintained with reduced suction power.
- the suction of the dirt collecting container 50 with simultaneous recharging of the battery 56 is then ended, and in method step 112 the suction device 12 can then resume its normal suction operation, in which it travels along the surface to be cleaned.
- the suction power of the suction station 14 can be reduced by actuating the feeler element 94 for a predetermined period of time of eight hours in the present example. This ensures that the floor cleaning system 10 has only a low level of noise, for example when cleaning a floor surface at night.
- the operating time is recorded with reduced suction power.
- the suction station 14 automatically switches to an operating mode with maximum suction power, the operating mode with reduced suction power only being activated again by pressing the pushbutton element 94 again.
- method step 103 in which the time span since the last docking process is checked, it can also be provided that in method step 103 it is checked whether, since the last mode of operation with reduced suction power, at least one suction of the dirt collecting container 50 with maximum suction power of the suction unit 56 was carried out. This ensures that a user can not easily restart the operating mode with reduced suction power after the operating mode with reduced suction power, but that the dirt collecting container 50 is suctioned off at least once with full suction power, so that even coarse dirt particles from the dirt collecting container 50 reliably into the Dirt holding container 58 are transferred.
