Definitions
- the present invention relates to a novel floor nozzle for hard floors.
- an attachable to a vacuum cleaner attachment which consists of a suction tube, a connectable with this mouthpiece and a suction tube arranged on the container for cleaning liquid, which accessory in Mund Nursinggeophuse a liquid-conducting connected to the container distribution strip and one of these , movably mounted applicator body is provided. Due to the arrangement of the container for cleaning liquid to the suction pipe of the vacuum cleaner, a liquid supply is possible only by gravity and a dosage of the correct amount of liquid is not possible.
- the present invention seeks to provide a comparison with the prior art improved arrangement with a dosage of the liquid in response to the operation of the floor nozzle.
- a floor nozzle for hard floors which has a liquid supply device for a wiper, which comprises a pump for delivering liquid from a liquid tank.
- a pump By using a pump, the liquid transport can be actively promoted.
- the pump can be controlled differently depending on different operating conditions. In particular, the delivery rate of the pump can then be increased if the floor nozzle performs a wet cleaning over a large area. On the other hand, the delivery rate of the pump can be reduced if the floor nozzle has only a small floor area to clean.
- the pump is designed to convey liquid in response to movement of the floor nozzle during the wiping operation.
- the delivery rate of liquid is controlled in dependence on how much floor area is swept by the floor nozzle.
- the wet wiper sweeps the floor, a certain amount of liquid is released to the floor. This means that if a large floor area is covered, the liquid consumption big. If, on the other hand, only a small floor area is covered, less liquid is consumed. Consequently, it is advantageous if the delivery rate of the pump is controlled in dependence on the movement, ie the frequency of movement of the floor nozzle.
- the pump is controlled by selective activation of the pump at certain intervals.
- the pump may have for its activation mechanical means which are actuated by the movement of the floor nozzle. Due to the mechanical activation of the pump, no additional energy supplies, such as electrical energy, are necessary. This makes the floor nozzle independent of external power supplies. Advantageously, therefore, the kinetic energy generated by the manual movement of the floor nozzle can be used for the activation of the pump. Another advantage is the fact that at the same time there is also a control of the pump, namely that very many movements also very much fluid is promoted and little fluid is promoted with a few movements.
- the pump may preferably have a pump body which can be activated in response to a movement of the floor nozzle.
- the pump body converts the kinetic energy into a pressure energy that promotes the liquid from the liquid tank to the wiper.
- the pump body may be a diaphragm of a diaphragm pump which can be activated by an inertia mass body movably mounted in the floor nozzle.
- the design of the pump body as a membrane offers a cost-effective solution that works largely trouble-free and thereby increases the reliability of diesstechniksförde- tion.
- the inertial mass body may be a ball which is mounted for displacement on the diaphragm to and away from the diaphragm due to its inertia in response to movement of the floor nozzle in the floor nozzle.
- the floor nozzle may have a groove in which the ball is guided for rolling.
- the channel is preferably oriented in the main direction of movement of the floor nozzle.
- the ball On the trough, the ball is free to move between a front stop end and a rear stop end. If the floor nozzle is moved forward, the ball rolls up Because of their inertia to the rear stop end of the channel. Then, when the floor nozzle is moved back, so the ball rolls in turn due to their inertia forward until it abuts the front end stop.
- the diaphragm of the pump may be located at the front end stop. Each time the ball strikes the diaphragm, a certain amount of fluid is pumped through the pump. With a similar effect, the diaphragm of the pump could also be provided at the rear stop end of the channel.
- the pump preferably has a supply line connected to the liquid tank and at least two discharge lines leading to the wiper agent.
- liquid can be conveyed out from a central common liquid tank and forwarded into a plurality of outflow lines. There are no additional Verteila,e Trenten necessary to divide the liquid flow. The division takes place directly in the pump.
- the pump may have at least one inlet valve and one outlet valve, which are connected to a pump chamber to prevent fluid transport in the rest position of the pump.
- the inlet valve and the outlet valve are fluidically connected in opposite directions in the liquid line, so that only a small amount of liquid can always be intermittently promoted. This has the advantage that no continuous flow connection is present and consequently no undesirable outflow of liquid, in particular in the rest position of the pump, can take place.
- the exhaust valves and intake valves are designed as flapper valves.
- Flap valves consist in a simple embodiment of a passage bore, which is covered by an elastic flag.
- the elastic flag may be formed as a simple Einlegefolienteil. As a result, a cost-effective production is possible and at the same time created a valve with high reliability.
- the pump can be operated in a simple embodiment with the foot.
- a pump is preferably provided, which is driven by a mechanism on the nozzle.
- the diaphragm of the pump is actuated during the suction movements.
- the ball runs in a path in the direction of the suction movements.
- the ball Due to the backward movement of the nozzle, the ball experiences a movement from the pump to the end of the track due to the inertia of the mass. Here the bullet hits and is thrown back.
- the meanwhile executed forward movement of the nozzle accelerates the ball by the rebound energy and the inertia of the ball towards the pump.
- this impinges on the pump diaphragm, presses it together and thereby conveys the fluid medium in the direction of the sponge of the floor nozzle.
- the nozzle moves backward, the ball moves away from the pump. As a result, the membrane is relieved again and attracts liquid medium from the tank.
- the liquid transport in the pump is preferably controlled by so-called flutter valves, which can only open to the respective direction when the corresponding pressure is applied.
- flutter valves which can only open to the respective direction when the corresponding pressure is applied.
- the figures show a preferred possibility of forming a pump for esp.
- Cleaning liquid on the nozzle for hard floors which is equipped with two suction channels, between which a wiper, especially a sponge provided with a cloth attached.
- the wiper is constantly supplied with water in the suction process, so that a constant humidity of the wiper is maintained.
- the wiper is attached to the nozzle so that it may be easily removed by the operator.
- a tank is attached, which can be removed for filling of the nozzle. From this tank, a pipe leads to a pump, which is designed so that it can carry water and also cleaning media.
- the outlet valves are opened and allow the cleaning medium to reach the wiping agent formed, for example, as a sponge cloth.
- the inlet valve opens and allows the cleaning medium get into the pump housing.
- both valves are closed and do not allow any medium flow.
- the pump can be optionally provided with one or two liquid outlets, which lead to a uniform liquid distribution and thus carry the same amount of liquid to the cloth.
- the pump is attached to the nozzle via a mechanism. exaggerated. By a ball, the diaphragm of the pump is actuated during the suction movements. The ball runs in a path in the direction of the suction movements.
