Definitions

• the invention relates to a device for ejecting liquid from a wiper body, which is held on a wiper head of a surface cleaning device, with a container in which a wiper head holder is rotatably mounted, into which the wiper head with the wiper body can be inserted and which means for dehumidifying the wiper body a drive device can be driven to rotate about an axis of rotation.
• a wiping body for example a wiping mop, a wiping pad or a wiping covering held on a wiping head to form a wiping surface, is often used to clean a soiled surface, in particular a floor surface.
• the wiper head with the wiper body is moved along the surface to be cleaned, so that dirt can be absorbed.
• the wiping body held on the wiping head can then be washed out and wrung out.
• WO 92/14394 A proposes to place the wiper head on a wiper head holder, which is then set in rotation so that liquid is thrown out of the wiper body due to the centrifugal forces acting on it. This has the advantage that the user does not have to come into contact with the cleaning liquid.
• the wiper head holder is arranged in a first container which can be positioned above a collecting container in which the liquid thrown out of the wiper body can be collected.
• a further container is provided in which the wiping head held on the wiping body can be washed out.
• a device of the type mentioned in which a multi-part container is used with a first container part, which has a centrifugal area for ejecting liquid from the wiper body, and with a second container part, which Surrounds washing area for washing out the wiper body. If the wiper head with the wiper body held thereon is inserted into the centrifugal area, an electric motor of the drive device is automatically activated and the wiper head holder is set in rotation together with the wiper head and the wiper body arranged thereon.
• the known device can be connected to a mains voltage via a connecting cable.
• the drive unit has a rechargeable battery which enables the device to be driven independently of the mains. For this purpose, it is desirable if the drive device uses as little energy as possible to eject the wiper body.
• the object of the present invention is to develop a device of the type mentioned at the outset in such a way that the energy consumption of the device can be kept low.
• the device comprises a measuring element for determining a degree of dryness or a spin time of the wiper body, the measuring element being associated with a display unit for indicating the achievement of a certain degree of dryness or the running of a certain one spinning time.
• the energy consumption of the device can be kept low by signaling to the user when the wiper body is ejected that a certain degree of dryness has been reached or that a certain spinning time has elapsed.
• the measuring element can be designed, for example, in the form of a sensor unit which detects the amount of liquid ejected and, in the presence of a certain amount of liquid and thus a certain degree of dryness, causes the display unit to display the degree of dryness.
• the measuring element is designed in the form of a timing element coupled to the drive unit. This makes it possible to record the spin time of the wiper head holder and the wiper head inserted into it by means of the measuring element and to activate the display unit after a certain spin time has elapsed.
• the display unit has at least one optical display element, for example a light-emitting diode.
• the display unit has an acoustic display element, for example a buzzer.
• the display unit preferably comprises a plurality of display elements each indicating the achievement of a certain degree of dryness or the expiry of a certain spin time.
• a particularly simple handling and a particularly low energy consumption of the device can be achieved in that the drive device can be switched off automatically when a certain degree of dryness is reached or after a certain spin time has elapsed.
• the desired degree of dryness or the desired spin time can be specified by means of an actuator.
• the actuator By means of the actuator, the user can specify the desired spin time or the corresponding degree of drying. When this degree of drying is reached or when the corresponding spinning time has elapsed, the display unit signals the desired end of the spinning process, so that the user can end the spinning process himself or the drive device switches itself off.
• the drive device is coupled to a control element which can be actuated by the user and which is arranged on the container.
• a control element which can be actuated by the user and which is arranged on the container.
• control element comprises a foot switch.
• the container comprises a centrifugal area and a washing area, the rotatable wiper head holder being mounted in the centrifugal area and the washing area receiving a cleaning liquid for washing out the wiping body, and the display unit and / or the control element being arranged below the washing area.
• the mop head is inserted into the mop head holder and rotated so that the mop body held on the mop head is dehumidified.
• the end of the spinning process is indicated to the user by means of the display unit, which can be arranged below the washing area.
• the control element is arranged below the washing area. It has been shown that this enables a particularly compact design of the device, the display unit being easily accessible to the user and the control element being able to be operated comfortably.
• a particularly thorough cleaning of the wiping body in the washing area can be achieved in that the washing area has a bottom wall oriented obliquely to the axis of rotation of the wiping head holder and thus obliquely to the vertical in the position of use of the device, which forms a washing plate with a friction surface facing the interior of the container, to which the Wiper body can be applied flat and along which the wiper body can be moved.
• the bottom wall in the form of the washing plate, forms a kind of washing board which enables the wiping body to be cleaned reliably by the wiping body being able to be moved back and forth there.
• the bottom wall is oriented obliquely to the vertical in the position of use of the device and enables easy handling of the device, since the wiper body can be displaced along the obliquely aligned friction surface, for example from top to bottom.
• control element and / or the display unit are arranged below the bottom wall.
• the bottom wall can cover a free space of the container, for example, the control element and
• the wiping body is held on the wiping head while forming a wiping surface and if the wiping head holder forms a receptacle into which the wiping head can be inserted with the surface normal of the wiping surface oriented obliquely or perpendicular to the axis of rotation of the wiping head holder.
• the wiper body is oriented during the ejection so that the surface normal of the wiper surface does not assume a position parallel to the axis of rotation of the wiper head holder, but the surface normal is oriented at an angle to the axis of rotation. It has been shown that droplets of liquid can be thrown out particularly effectively by such an alignment of the wiping surface. This enables a particularly high degree of efficiency to be achieved. This makes it possible to achieve effective dehumidification of the wiper body within a short time, even at relatively low speeds, so that relatively low energy consumption is required to dehumidify the wiper body.
• the receptacle receives the wiping head with the surface normal of the wiping surface oriented perpendicular to the axis of rotation. This enables a particularly compact design of the device.
• plate-shaped wiping bodies can be dehumidified in an advantageous manner, which form a wiping surface both on their top side and on their underside and can therefore be used on both sides.
• Such wiping bodies are usually held on a wiping head to which a handle or handle is articulated laterally.
• the wiping head with the wiping body held thereon can be pivoted relative to the handle or handle such that, alternatively, the top or the underside of the wiping body faces the surface to be cleaned.
• This pivotable mounting of the wiper head on the handle or handle simplifies the use of the wiper head with the wiper body held thereon in the receptacle of the wiper head holder such that the surface normal of the wiping surface is exposed perpendicular to the axis of rotation of the wiper head holder.
• the container is designed like a bucket. It is advantageous here if the container comprises an integrally formed base body which surrounds the centrifugal area and the washing area and which has an indentation which can be covered by a cover and defines a drive space which receives the drive device.
• the drive area is arranged below the centrifuge area and that the washing area extends laterally next to the centrifuge area and the drive area, forming an insertion section at the level of the centrifugal area and a liquid absorption area at the level of the drive area absorbs the cleaning liquid.
• the liquid absorption area can reach under the centrifugal area and thus, despite the relatively small design of the container, have a relatively large capacity for cleaning liquid.
