Description

cleaning equipment

The present invention relates to a cleaning apparatus for cleaning a surface, in particular for cleaning a fabric surface or a twisted surface, wherein at least one gaseous pressurized pressure medium and at least one cleaning utility are provided, both of which can be rotated The swirl sleeve, the nozzle tube and the ball bearing form a vortex in the nozzle element of the cleaning device.

The above-mentioned cleaning device is disclosed, for example, in DE 20 2009 013 337 U1. In conventional cleaning apparatus, compressed air enters and passes through the nozzle assembly and is again discharged at the nozzle opening. The nozzle opening is provided at the end of a rigid curved tubular member which is mounted by means of a ball bearing for rotation about a rotational axis. The end of the tubular member is eccentrically disposed relative to the axis of rotation and is curved such that when the compressed air exits, an allotropic component is formed, and the rotatable tubular member rotates under the tangential component. Conventional cleaning devices have a cleaning fluid container through which the cleaning fluid enters the nozzle assembly through a flexible hose. The flexible hose extends to the outlet end of the rigid tubular member in a rotatably mounted manner, here also the discharge of compressed air. Compressed air takes the droplets away from the flexible hose and atomizes them. At the same time, the mist rotates under the rotation of the rotatable pipe. The air-cleaning liquid mixture thus swirling and rotating thus exits the funnel member via the open side of the funnel member around the nozzle member to further reach the surface to be cleaned.

The purpose of this creation is to improve the cleaning efficiency and cleaning process time of the aforementioned types of cleaning equipment.

This work proposes to set up steam as the solution for this pressure medium. The steam mainly releases heat when condensing, and the heat is used to heat the surface to be cleaned so that the dirt particles It is easier to fall off. This shortens the cleaning process and reduces the amount of detergent used. In most cases it is no longer necessary to use special detergents, because in many cases, the use of only steam is sufficient to remove the dirt particles. In the latter case, the delivery of cleaning liquid to the cleaning device can be stopped.

In a preferred embodiment of the present invention, steam and compressed air are provided as the pressure medium for alternate use. After cleaning with steam, the steam can be shut off and the compressed air valve opened. Compressed air is used to dry the cleaned surface and is very effective because the surface has previously been heated by steam to form rising moisture, which is effectively blown away by compressed air.

In addition to the use of compressed air to dry the cleaned surface, the present invention has the advantage that the cleaning device can operate in a conventional manner in the prior art with compressed air as the pressure medium and cleaning liquid as the cleaning agent.

According to a further development of the present invention, the cleaning device has a suction device for aspirating the cleaning agent or water from the surface to be cleaned. In a preferred embodiment, the suction device is constructed of a wet and dry vacuum cleaner having a nozzle coupled to a funnel member that surrounds the nozzle member. Wherein, the suction can be performed simultaneously with the spraying process. Another advantage is that the drying process is preferably carried out using compressed air, which is more effective in removing the cleaning agent that is sucked in the liquid state or the water formed by condensation of water vapor. However, compressed air can be used as a supplemental drying means to eliminate moisture that has not been pumped away.

For special dirt, it is beneficial to set dry ice as a cleaning agent. Dry ice can violently cool the dirt particles to be removed, at least partially away from the surface to be cleaned. After further mechanical action is applied, the dirt particles will completely fall off and be blown away or be sucked up by a suction device that may be present.

In a further advantageous development of the present invention, the cleaning device further has a pulsation device which can be switched on with a switch to cause the pressure medium discharged from the nozzle tube to pulsate. The discharge of steam or compressed air thereby forms a pulsation, thereby improving the scavenging effect of the stubborn.

Embodiments of the present creation will be described in detail below with reference to the drawings.

Figure 1 is a partial cross-sectional view of the cleaning apparatus of the present invention.

The illustrated cleaning apparatus is implemented as a cleaning gun, including a handlebar 12, and a steam joint 11 at its lower end for connecting a steam pipe (not shown) to deliver steam. The steam line is closed by a valve hidden in the handlebar. The steam pipe can be opened by the lever 13. Then, the steam passes through the tubular connecting member 14 to reach the nozzle member 10 connected to the connecting member 14, which is composed of a rigid tubular member 31, a rotary sleeve 32 rotatably mounted on the rigid tubular member 31 by the two ball bearings 35, and The rotary sleeve 32 is constructed of a nozzle tube 34 that is connected in a twist-proof manner.

Alternatively, a sleeve member may be used in place of the rotating sleeve 32 to be rotationally coupled to the rigid tubular member 31. In this case, the rotary nozzle tube 34 is rotatably attached to the inside of the sleeve member by the ball bearing 35.

Alternatively, a single bearing (for example, a sliding bearing or a roller bearing extending in the direction of the rotation axis) may be provided instead of the two ball bearings 35.

The liquid container 21 is connected to one of the connecting members 14 via a blocking valve 23. The flexible liquid conduit 24 extends into the liquid container 21 to draw the liquid therein, which liquid reaches the flexible hose 15 via the open blocking valve 23, which extends inside the connecting member 14 towards the nozzle element and runs therethrough The rigid tubular member 31, the rotating sleeve 32 and the nozzle tube 34 extend to the open end of the nozzle tube 34. With the blocking valve open and the lever 13 actuated, the compressed air flows through the nozzle element 10 until it reaches the end of the nozzle tube 34 and exits there. During this process, the compressed air carries the liquid away from the flexible hose 15 that also terminates at the end of the nozzle tube 34 and atomizes it. At the same time, the nozzle tube 34 is rotated about the axis of rotation defined by the ball bearing 35 in the direction indicated by the direction of the rotary arrow 30. The mist 25 formed between the compressed air and the cleaning liquid is rotated until it reaches the surface to be cleaned. A sheath member 16 is provided around the nozzle element 10, and the rotary mist 25 is discharged from the opening side thereof.

The gun handle 12 is provided with a connection air compressor (not shown) in addition to the steam joint 11 The compressed air joint 17 of the road. The state in which the steam is delivered through the steam joint 11 is converted by the converter 18 to the state in which the compressed air is supplied through the compressed air joint 17. For example, the surface can be cleaned with steam first and then dried with compressed air.

The cleaning apparatus of the present invention is provided with a suction device 40 to support the drying process after the cleaning process, which is only schematically shown in FIG. The suction device is a conventional dry and wet vacuum cleaner which is connected via a suction hose 41 to a suction nozzle 42 which in turn is connected to a sheathing member 16 which surrounds the nozzle element 10. In this way, liquid or liquid mist can be absorbed from the cleaned surface through the suction nozzle 42. For this purpose, the open end of the sheathing member 16 is preferably placed on the surface to be suctioned.

The pulsator 50 is also provided with a pulsating device 50 that can be manipulated by a switch 51. After the pulsation device 50 is turned on, the steam flow or the compressed air flow is periodically interrupted, so that the pressure medium discharged at the open end of the nozzle tube 34 is pulsed.
