Definitions

  • the invention relates to a cleaning tool for a floor cleaning appliance with a base body, which carries a cleaning pad subject to wear, and with a signal generator, which provides a wireless signal depending on the degree of wear of the cleaning pad.
  • Floor cleaning equipment such as sweepers, scrubbers or floor polishing machines, have a cleaning tool with a body carrying a cleaning pad.
  • the cleaning pad can be configured for example in the form of a bristle covering, a polishing pad or a cleaning pad and is subject to increasing wear when using the cleaning tool. Upon reaching a maximum allowable degree of wear, the cleaning tool should be replaced, otherwise there is a risk of damage to the floor surface to be cleaned and also the achievable cleaning result is insufficient.
  • the wear of the cleaning pad is often visually inspected by the user. However, this is in many cases associated with difficulties, since the cleaning tool is often positioned in a housing of the floor cleaning device and therefore can not be readily viewed by the user from the outside.
  • Object of the present invention is to develop a cleaning tool of the generic type such that wear of the cleaning pad can be detected in a cost effective manner.
  • the signal generator is designed to be rigid and fixed to a movable support member, wherein the support member is held on the base body and from a normal position against a restoring force in a deflection position is movable, wherein the support member in the basic position further protrudes from the base body than in the evasive position and wherein the support member and / or the signal transmitter contacted when reaching a maximum allowable degree of wear of the cleaning surface to be cleaned bottom surface.
  • a rigid signal generator is used, which is fixed to a movable support member.
  • a signal generator a standard part can be used, such as a permanent magnet or a transponder that can be produced inexpensively in very large quantities.
  • the support member is held on the base body and can be moved, starting from a basic position against the action of the restoring force in an evasive position. In the basic position, the support part protrudes further out of the main body than in the evasive position.
  • Upon reaching a maximum allowable degree of wear of the cleaning pad contacted the support member and / or the signal generator to be cleaned bottom surface. This has the consequence that upon further use of the cleaning tool, the support member and / or the signal transmitter are affected by the bottom surface. This ultimately leads to damage of the support member and / or the signal generator, and this in turn has the consequence that the wireless signal provided by the signal generator changes.
  • the signal transmitter is damaged or even destroyed after exceeding a maximum allowable degree of wear of the cleaning surface of the floor or detached from the support member.
  • the signal generator provides a predetermined wireless signal until a maximum permissible degree of wear of the cleaning pad is reached and the signal abruptly changes or stops when the maximum permissible degree of wear of the cleaning pad is exceeded.
  • the floor surface is cleaned by contacting the cleaning surface with the floor surface.
  • the cleaning surface is pressed against the floor surface when cleaning the floor surface.
  • the cleaning tool is held in many cases on the floor cleaning device movable.
  • the force with which the cleaning pad is pressed against the floor surface can often be influenced by the user.
  • the type of floor surface cleaning surface can be pressed with different force against the floor surface. This has the consequence that the cleaning surface is more or less compressed when cleaning the bottom surface.
  • the achievement of the maximum allowable degree of wear of the cleaning pad without the user for this purpose must visually inspect the cleaning pad.
  • This ensures that the support member and / or the signal generator are affected by the bottom surface only when reaching the maximum permissible degree of wear of the cleaning, without already a strong compression of the cleaning pad leads to such a deterioration of the support member and / or the signal generator.
  • a rigid signal transmitter there is thus no risk that the bottom surface will be damaged during normal operation of the cleaning tool by the signal generator or the support member.
  • the cleaning tool is rotatable about an axis of rotation and the support member is relative to the axis of rotation of the cleaning tool in the radial or axial direction between the basic position and the alternate position movable back and forth.
  • the cleaning tool is configured as a plate brush, which is mounted rotatably about a substantially vertically oriented axis of rotation on the floor cleaning device, wherein the support member in the axial direction between the basic position and the escape position is movable back and forth.
  • the cleaning tool is designed as a roller brush, which is mounted rotatably about a substantially horizontally oriented axis of rotation on the floor cleaning device, wherein the support member in the radial direction between the basic position and the alternate position is movable back and forth.
  • the signal transmitter projects out of the main body in the basic position of the carrying part and is completely surrounded by the carrying part in its protruding area.
  • the support member forms a protective jacket which surrounds the signal generator at least in its protruding from the body region.
  • the signal transmitter protrudes completely in the basic position of the support member from the main body of the cleaning tool and is completely surrounded by the support member.
  • the support member forms a protective sleeve which surrounds the signal generator in the circumferential direction.
  • the signal generator can be inserted into the protective sleeve and fixed in the protective sleeve.
  • the protective sleeve may be formed, for example in the form of a circular cylinder.
  • the support member can be applied to the surface to be cleaned upon reaching a maximum allowable degree of wear of the cleaning pad.
  • the further use of the cleaning tool then has the consequence that the support member slides along the bottom surface and is mechanically influenced by the bottom surface.
  • the support member may be ground off the floor surface.
  • the increasing mechanical influence of the support member may, after a short time, cause the signal provided by the signal generator fixed to the support member to undergo a change. This signal change can be detected by a signal receiver and thereby the user can be signaled that the cleaning pad has exceeded its maximum permissible degree of wear.
  • the support member is destructible upon reaching the maximum allowable degree of wear of the cleaning pad by using the cleaning tool.
  • the destruction of the support member can be done by contact with the ground surface.
  • the support member breaks into at least two parts.
  • the fixation of the signal transmitter is adversely affected on the support member and this in turn leads to a change in the signal provided by the signal generator after the cleaning pad has reached its maximum allowable degree of wear.
  • the signal transmitter can be removed from the base body when the maximum permissible degree of wear of the cleaning surface is reached. For example, it may be provided that the signal transmitter is thrown off the base body moving relative to the bottom surface when the maximum permissible degree of wear of the cleaning coating is reached. As a result, the signal generator no longer provides a user-detectable signal. The absence of the signal thus signals the user that the cleaning pad has reached its maximum allowable degree of wear.
  • the signal generator is designed as a transponder.
  • the signal generator thus forms a radio communication link, which incoming Receives and answers signals.
  • a wireless transmission channel between the cleaning tool and an external reading device of the floor cleaning device can be achieved.
  • the transponder has a data memory in the form of a read / write memory and may additionally include a control logic.
  • the transponder has an antenna coil.
  • the transponder can be supplied with energy and its data memory can be read out.
  • the transponder is equipped with its own power source.
  • RFID Radio Frequency Identification Technology

  • the base body is cylindrical in shape and, relative to the cylinder axis, has a radial bore or a bore aligned parallel or obliquely to the radial direction into which the guide part can be inserted.
  • the guide part can be latched to the base body.
  • the guide member may for example have latching elements which occupy a latching position when inserting the guide member into the body, so that the guide member the basic body can not be readily removed more.
  • the base body is designed as a hollow cylinder and has a preferably radially aligned bore into which the guide member is insertable, wherein at least one locking element of the guide member after insertion of the guide member into the bore to an inner side of the hollow cylindrical body can be applied.
  • the support member on a support body which receives the signal transmitter, and a connectable to the main body of the cleaning tool base body which is connected via an elastically deformable spring body with the support body.
  • the base body can be used, for example, in a receptacle of the main body of the cleaning tool and the carrier receiving the signal carrier can be moved by providing the elastically deformable spring body relative to the base body between a basic position and an alternate position back and forth. When moving from the basic position in the alternate position of the support body can be acted upon by the elastically deformable spring body with a restoring force.

  • the cleaning tool can be designed as a cleaning brush rotatable about a rotation axis. It is advantageous if in the direction of rotation of the cleaning brush in front of the signal generator cleaning bristles are arranged, which cover the signal generator during use of the cleaning tool until it reaches a maximum allowable degree of wear of the cleaning bristles at least partially.
  • the cleaning bristles protrude from a body of the cleaning brush to the outside.
  • the cleaning bristles can protrude in the radial direction from the main body of the cleaning brush relative to the axis of rotation of the cleaning brush.

  • cleaning bristles In the direction of rotation of the cleaning brush in front of the signal generator arranged cleaning bristles cover this as long as the signal generator at least partially until the cleaning bristles have reached their maximum allowable degree of wear. After reaching the maximum permissible degree of wear The cleaning bristles can no longer cover the signal generator so that it contacts the floor surface and is thus affected by the floor surface. This can lead to a change, and in particular to a cancellation of the signal provided by the signal generator, and this signal change can be detected by the user.
