Description

  The present invention relates to a cleaning accessory according to the superordinate concept of claim 1.

  Vacuum cleaner attachments and bottom nozzles are known, and with these aids, the surface of the fabric, such as mattresses and cushions, can be cleaned. At that time, dirt is sucked in, and certainly the odor cannot be neutralized at all. In addition, bacteria and molds can be sucked unnecessarily and therefore remain stored in the fabric.

  In addition, there are UV lamps that are effective on the surface, where they kill bacteria and mold. It is not possible to reach the area inside the fabric and the effect is very limited. In addition, the walls can be attacked by fungi, particularly in humid residential areas. The mold has usually been eradicated using powerful chemicals.

  Patent Document 1 discloses a suction head for an electric vacuum cleaner. In this suction head, negative and positive ions are generated using an ion generator, and these ions cause the hair of a brush roller to be electrically connected. To charge. Thereby, since the static electricity is high, dirt particles are absorbed. In this case, the surface cannot be cleaned or sterilized by killing organic bacteria, and the odor cannot be removed. In addition, the ion generator is contaminated with absorbed dirt particles and cannot be assisted by the aspirated air.

  SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a cleaning accessory for a vacuum cleaner that enables cleaning of a deep portion and efficiently removes odor.

  This problem is solved by a cleaning accessory having the features of claim 1.

  According to the present invention, a cleaning accessory includes a housing, a connection for a suction pipe, at least one suction hole for ambient air, and a plasma generator for generating plasma provided in the housing. And at least one exhaust hole or flow path, and the mixture of plasma and air is cleaned along the exhaust hole or flow path before the mixture is sucked into the housing and through the connection. Collide with the surface to be. The cleaning accessory can then be handled to sterilize air and dirt and to neutralize odors. Through the cleaning opening or flow path, the air and plasma mixture is guided to or along the surface to be cleaned. Since the plasma contains ozone, bacteria and mold are killed. Surface cleaning takes place in a cleaning opening free of liquids or additives due to the formation of a flow profile. Therefore, such cleaning is particularly material compatible and does not impair the use of the object.

The housing is preferably divided into an overpressure chamber and a negative pressure chamber by a gas permeable partition. This ensures that the flow is from the overpressure chamber to the negative pressure chamber. Furthermore, it is of course possible to form the partition walls in a gas-permeable manner, so that no direct flow occurs between the overpressure chamber and the negative pressure chamber, but through the cleaning opening. In that case, ambient air is sucked in through a blower, preferably through a ventilator. This creates an overpressure that increases the penetration depth of the plasma into the surface to be cleaned. Preferably, the flow resistance of the gas permeable partition is adjustable. As a result, the activated air reaches the negative pressure chamber, where odors and bacteria can be eliminated.

  In one embodiment of the present invention, the at least one cleaning opening includes an outflow opening for flowing out a mixture of plasma and air and an inflow opening for allowing the mixture to flow into the housing. Due to the pressure and flow relationship, a mixture of air and plasma is flowed for a predetermined section outside the housing where it is used for cleaning. The spacing between the outflow opening and the inflow opening can be formed as a strip with a width between 0.5 cm and 5 cm, preferably between 1 cm and 2 cm. This ensures that after killing the bacteria, the organic residue dead on the surface to be cleaned is absorbed into the negative pressure area of the cleaning accessory.

  The cleaning accessory is configured such that the volume flow flowing through the inlet (Ansaugoffnung) is preferably less than the volume flow flowing through the connection (Anschluss) for the suction pipe (Saugrohr) by more than 20% It is preferable. As a result, the ambient air as well as the mixture of plasma and air are sucked into the cleaning opening, thereby improving the cleaning performance.

  A power supply (Stromspeicher) for supplying a plasma generator is preferably provided for self-sufficient energy supply.

In addition, the cleaning accessory may additionally comprise a device for cleaning mechanically, in particular a rotary brush roller. In that case, the brush roller may be provided between the exhaust port for allowing the mixture of plasma and air to flow out and the suction port for allowing the mixture to flow into the housing.

  In order to make the structure compact, the plasma generator may include one or more frames for enclosing at least a part of the brush roller.

  According to an advantageous embodiment of the power supply, a generator is provided, which is connected to the drive mechanism or brush roller with a belt drive mechanism, in which case the kinetic energy of the brush roller or wheel is converted into electrical energy. Convert.

  In a preferred embodiment, the plasma generator is placed parallel to the brush roller so that the plasma density is generated directly near the brush roller by fully using the width of the housing.

  In another preferred embodiment, the plasma generator is arranged perpendicular to the brush roller. In this case, the plasma generator surrounds a part of the brush roller and is thus configured to generate a high plasma density in the vicinity of the brush roller as well.

  According to a preferred embodiment of the present invention, a housing is provided, and the housing is provided with rubber packings in various directions on the surface to be cleaned along the contact surface of the housing. Thus, an optimization of the flow profile of the air and plasma mixture is achieved on or in the surface to be cleaned. Furthermore, a large amount of suction of dirty air is achieved by high dust collection performance, and an enhanced negative pressure is constructed.

  The invention will be described in more detail below with reference to the accompanying drawings on the basis of several embodiments.

In this case, the flow resistance of the gas-permeable partition wall 9 may be adjustable by a filter structure having a passage in which the bridge portion (Durchlassquerschnitt) is changed, for example. High flow resistance reduces the amount of inhaled mixture consisting of ambient air and plasma.

  In order to supply power to the plasma generator 2 and the blower 5, a power source 19 incorporated in the housing 3 is provided. In this case, the plasma generator 2 is provided with a plurality of rod-like bodies or conduits, which extend parallel to the rotation axis of the brush roller 12 and surround a part thereof.
