Definitions

  • the present invention relates to a floor cleaning machine with a machine frame, with a chassis provided on the machine frame for moving the machine over a floor area to be cleaned, with a dirty water tank, with a suction device attached to the machine frame for sucking liquid from the floor area, the suction device having a Dirty water supply line is connected to the dirty water tank, with a suction device which is driven by a motor and which is connected on the suction side to the dirty water tank via a connection provided on the dirty water tank to generate a negative pressure inside the dirty water tank via a suction line, with a float valve being provided in the dirty water tank that is designed to close the connection to the suction line when the liquid level in the dirty water tank reaches a maximum level. Furthermore, the present invention relates to a method for operating a floor cleaning machine.
  • An electronic device with moving parts for detecting the liquid level inside the dirty water tank would be severely attacked by the dirt dissolved in the dirty water and the cleaning agents also present in it, or dirt would settle on it, which in turn would affect the operational safety and reliability of the measuring system.
  • additional components are required to record the liquid level in the waste water tank.
  • a mechanical float valve closes the tank-side connection for suction when a predetermined level is exceeded. Due to the lower pump volume then, the motor speed increases and the motor current of the electric motor, which drives the suction, decreases. Based on at least one of the changed parameters of the motor speed or motor current, a controller generates a signal that automatically switches off the suction, for example, or at least outputs a signal to the user.
  • the US 2002/0042965 A1 describes a floor cleaning machine with a sensor that can measure a pressure in a supply line that connects a suction port to a dirty water tank.
  • this object is achieved according to claim 1 in that a measuring device is provided which is designed to detect a differential pressure between a first gas pressure in the dirty water tank and a second gas pressure in the suction line, and that the measuring device is configured is to generate a first signal when the differential pressure threshold value is not reached and/or to generate a second signal when the differential pressure threshold value is exceeded.
  • the liquid level is below the maximum level and the suction connection is open. Due to the unclosed connection to the extraction system, essentially the same negative pressure prevails during operation of the extraction system both in the extraction line and in the waste water tank above the waste water level.
  • the differential pressure measured by the measuring device between the first and the second measuring point is essentially equal to zero, i.e. the gas pressure above the liquid surface in the dirty water tank essentially corresponds to the gas pressure in the unsealed suction line. Therefore, for example, because the maximum level has been undercut, a corresponding first signal can be displayed, which stands for the full performance of the machine.
  • the measuring device In the second state, the liquid level in the waste water tank has reached the maximum level and the float valve closes the connection for suction. As a result, a negative pressure is only generated in the suction line between the connection to the dirty water tank and the suction by this, while the gas pressure in the dirty water tank above the liquid surface is at ambient level.
  • the measuring device therefore measures a differential pressure between the first and the second measuring point, which differs significantly from the differential pressure in the first state. Therefore, if the determined differential pressure exceeds a predetermined differential pressure threshold value, the measuring device can emit a second signal which, for example, switches off the suction motor and/or indicates to the user that the dirty water tank is full.
  • the measuring device is designed in such a way that only the first signal is output when the differential pressure threshold value is undershot, but a second signal is not output when the differential pressure threshold value is exceeded.
  • the opposite the first signal can be dispensed with and only the second signal is output when the differential pressure threshold value is exceeded.
  • the measuring device of the floor cleaning machine according to the invention, a clear distinction can be made between the case of normal cleaning operation and the case in which reaching a maximum level in the dirty water tank leads to the float valve closing, without the need for electrical contacts in the area of the float valve that could pollute.
  • the floor cleaning machine according to the invention works reliably, in particular when cleaning smooth floors with a large amount of liquid, and a corresponding signal is only output when the float valve is actually closed.
  • the float valve has a float that can close the connection.
  • the floating body can have a shape corresponding to the connection. It is also conceivable that the floating body has an essentially spherical shape and the connection has a cylindrical shape or is merely an opening terminating with the tank wall.
  • the floating body can be made of any buoyant material, preferably with a low density and high resistance to cleaning agents.
  • the floating body is guided in a tubular cage, which opens into the connection, so that when the liquid level is appropriate, the floating body interrupts the air flow generated by the suction in the connection.
  • a tubular cage which opens into the connection, so that when the liquid level is appropriate, the floating body interrupts the air flow generated by the suction in the connection.
  • a driven brush head for engaging with the floor surface, a control for the suction and a control for the driven brush head are provided, with the measuring device being designed to transmit the signal generated by falling below or exceeding the differential pressure threshold to the control of the suction and /or forward the control of the brush head.
  • control of the suction and/or the control of the brush head are connected to the measuring device, and the control of the suction and the control of the brush head are designed in such a way that when the signal from the measuring device is present, the suction and/or the Drive of the brush head can be switched off. This enables a particularly energy-saving operation of the floor cleaning machine according to the invention.
  • the measuring device has a first and a second sensor, the first sensor being designed to measure the first gas pressure in the dirty water tank and the second sensor being designed to measure the second gas pressure in the suction line. Using the measurement signals from the first sensor as the first measurement point and the second sensor as the second measurement point, the measuring device can determine the pressure difference and derive from this whether the liquid level in the waste water tank has reached the specified maximum level and the float valve is closed or not.
  • the first and/or second sensor can work piezoresistively, piezoelectrically, inductively, capacitively, mechanically or resistively.
  • the measuring device can preferably have a differential pressure switch, which has a first pressure detection connection and a second pressure detection connection, which are functionally and/or communicatively connected to a pressure switch.
  • the first pressure detection port detects the first gas pressure and the second pressure detection port detects the second gas pressure. If a pressure difference between the first and the second pressure detection connection is greater than a predetermined threshold value, i.e. if the pressure difference is above a switching threshold, in the simplest case a contact is opened or closed by the pressure switch.
  • the measuring device comprises a third sensor arranged adjacent to the bottom of the waste water tank, the third sensor being configured to measure a liquid pressure, ie the pressure resulting from the weight of the liquid and the pressure above the liquid level of the third sensor, and wherein the measuring device is designed to generate a signal from the first gas pressure in the dirty water tank and the liquid pressure, which signal corresponds to a fill level of the liquid in the dirty water tank.
  • the fill level of the liquid also known as the liquid level, can in particular be an absolute fill level.
  • the measuring device it is thus possible for the measuring device to have a third sensor in addition to the first two sensors for measuring a gas differential pressure. It is also possible that the measuring device has only a first sensor and a third sensor and thus implements an independent, inventive measuring concept for measuring an absolute liquid level.
  • the measurement signal from the third sensor can be used to determine, together with the measurement signal from the first sensor in the dirty water tank and the measuring device, a signal which is, for example, proportional to the absolute liquid level in the dirty water tank.
  • the determination of the absolute liquid level via the liquid pressure and the gas pressure in the waste water tank is an independent inventive concept which can be used in addition to the gas differential pressure measurement according to claim 1. However, this determination of the absolute liquid level can also be used independently, i.e. without a pure gas differential pressure measurement between a first gas pressure in the dirty water tank and a second gas pressure in the suction line.
  • a (further) differential pressure switch is used to detect the maximum level in the dirty water tank, one pressure detection connection of which detects the first gas pressure above the liquid level and the second pressure detection connection of which the liquid pressure at the bottom of the tank.
  • the differential pressure switch that is used to determine whether the port is closed and that is used to determine whether the maximum level has been exceeded can use a common first pressure detection port. If the pressure difference detected by the further pressure difference switch exceeds a threshold and the switch closes or opens, this indicates that the maximum level has been reached.
  • a statement can be made as to whether the float was caused by foam or raised by the liquid surface.
  • This information can, for example, be relevant for the user when emptying the dirty water tank and can help the user to decide whether or not the dirty water tank needs to be additionally rinsed to remove the foam.
  • the third sensor can also work piezoresistively, piezoelectrically, inductively, capacitively, mechanically or resistively.
  • the above object is achieved by a method for operating a floor cleaning machine with a machine frame, with a chassis provided on the machine frame for moving the machine over a floor area to be cleaned, with a dirty water tank, with a Suction device attached to the machine frame for sucking up liquid from the floor surface, the suction device being connected to the dirty water tank via a dirty water supply line, with a suction device which is driven by a motor and which, in order to generate a negative pressure inside the dirty water tank on the suction side, is connected to this via a device provided on the dirty water tank Connection is connected via a suction line, wherein a float valve is provided in the dirty water tank, which is designed to close the connection when the liquid level in the dirty water tank exceeds a maximum level, appel i
