DE202004011275U1 - Vibratory cleaner for textiles and solid objects, has piston moving in gas-filled cylinder to transmit pressure pulses to balloon in closed chamber containing sealed balloons to form resonating system - Google Patents

Abstract

The vibratory cleaner has a closed chamber (1) filled with water or other incompressible fluid. Textiles and solid objects may be introduced into the chamber through a lid (4) which may be removed or sealed tight. Oscillations are generated by a pneumatic drive (3) consisting of a piston moving in gas-filled cylinder. The pressure pulses are transmitted through a hose (6) to a balloon acting as a pulsator (5) immersed in the fluid in the sealed chamber. The chamber contains sealed balloons (2) which contract as the pulsator balloon expands. The chamber and balloons form a resonating system, and the frequency of pulsations generated by the piston and cylinder is chosen to give maximum resonance.

Description

For soiled objects, preferably textiles and solid surfaces, cleaning devices are known which float in or immerse in the cleaning liquid and infrasonic waves, e.g. B. with unbalance motors, generate ( DE 195 00 889 respectively. DE 295 00 492 ). The infrasound waves are in the range from 30 to 150 Hz, in particular at 50 Hz. An infrasound wetting and cleaning ball has also been proposed, which contains, among other things, a generator for mechanical infrasound waves. ( DE 9319129 ).

The Waves generated by these devices trigger fluid movements that mixing in the liquid and thus cause the cleaning of the objects.

Of The disadvantage is that the frequency with the previously known devices generated infrasound waves not optimal for high mixing and thus good cleaning effect with low energy and cleaning agent expenditure is.

The The invention specified in claim 1 is based on the problem a cleaning device with a high cleaning effect to create low energy and detergent consumption.

The Problem is according to protection claim 1 solved by a device for cleaning objects, in which is in a container for the cleaning solution and the goods to be cleaned, in particular textiles and solid surfaces, at least one Pulsator for generating infrasonic waves and at least one Resonator for generating a resonance frequency and a sensor, which is the frequency of the vibratable Systems captured and through feedback the respective resonance frequency of the sensor signal to the pulsator discontinues or maintains are located.

The resonance frequency achievable with this device causes a high degree of penetration, which is effective cleaning at low Energy and detergent consumption enabled.

The Pulsator is either elastic with a pneumatic drive or rigid provided with electromagnetic or piezoelectric drive. With an electromagnetic or piezoelectric excitation higher Frequencies possible than with a pneumatic actuator.

As Sensors for detecting the vibration frequency are suitable for inductive, optical or acoustic sensors.

The The resonator is either an elastic gas space, e.g. a gas-filled elastic Bubble, or the airspace over the liquid surface in one closed container.

The The device either has a mass balance or is spring-loaded.

example 1

According to an embodiment of the invention. 1 the device consists of a closed cleaning device with mass balance, the pulsator 5 and the resonators 2 generate elastic gas spaces. The mass balance takes place through the counter movement of the liquid areas between the pulsator and the resonators. The housing 1 is through a lid 4 locked.

The pulsation exciter 3 , the z. B. can be designed as a piston or membrane, is via the hose 6 connected to the pulsator. The material to be cleaned is through the lid opening 4 introduced. If the applied pulsation frequency corresponds to the natural frequency of the system, resonance occurs. An intensive self-movement of the liquid is induced. The maximum pulsation amplitude is a few millimeters.
