DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The invention concerns a washing and cleaning device of the type including a sealed housing inside of which an electrically driven device for generating vibrations transferable from the housing to its environment is arranged.
BACKGROUND OF THE INVENTION
From DE-Utility Model 90 02 289 a washing and cleaning device operating with an ultrasonic generator arranged inside a housing is known. This device has a cost-intensive structure and does not work very reliably.
OBJECTS AND SUMMARY OF THE INVENTION
It is the object of the present invention to modify a device of the type mentioned above such as to have a simple structure and an effective washing performance, to work reliably, and to be easy to transport and usable in any desired location.
This object is achieved by means of a washing a cleaning device comprising a sealed housing inside of which an electrically driven device for generating vibrations transferable from the housing to its environment is arranged, and having an electric motor arranged in the cavity of the housing and rigidly secured to the inner wall thereof, as well as an imbalanced mass generating the vibrations being arranged outside the axis of rotation and on the output shaft of the electric motor.
Advantageous and expedient modifications of the problem solution of the present invention are as set forth below.
The invention is characterised by a simple structure and virtually does not require any maintenance work. It can be produced at a relatively small size and can be used in just about any location.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention is explained in detail below by making reference to the appended drawing showing embodiments, wherein:
FIG. 1 is a first embodiment of a washing and cleaning device; and
FIG. 2 is a second embodiment of a washing and cleaning device.
Identical reference numerals in the figures of the drawing designate equivalent elements.
DETAILED DESCRIPTION OF THE INVENTION
The drawings show a housing 2 in the form of a hollow sphere composed of two sphere shells 4, 6 sealingly welded together.
The housing 2 contains an electric motor 10 rigidly secured to the housing inner wall e.g. by strut elements 8, with an unbalanced mass or flywheel 14 for generating vibrations being arranged outside the rotation axis and on the output shaft 12 thereof. The electric motor 10 operates at a rotational speed of 8,000-15,000 rpm.
For a power supply, a current source having the form of an accumulator 16 is provided inside the housing--cf. FIG. 1--with a switch 20, preferably a reed switch, arranged on the housing wall being connected along the power line 18 towards the electric motor 10. The accumulator may be re-charged via a connection 22 arranged in or on the housing wall.
Instead of the accumulator, a power supply unit 24--cf. FIG. 2--arranged outside the housing 2 or inside the housing (indicated in broken lines) may also be provided as a current source.
The housing 22 preferably is made up of plastics material and may e.g, have a diameter of 77 mm.
Operation of the described device is carried out as follows. The spherical housing is introduced into the articles to be washed or cleaned with the electric motor switched on. The vibrations generated by the device are transferred to the washing or cleaning liquid and simply and rapidly detach dirt particles from the articles to be washed or cleaned. Adding detergent or soap generally is not required; the washing or cleaning process is, however, accelerated by the addition of detergent or soap. By means of the described device, considerable amounts of detergent may be saved to thus at the same time relieve the strain on the environment caused by detergents.
1. A washing and cleaning device, comprising: vibrations transferable from said housing to its environment; secured to an inner wall thereof; generating the vibrations being arranged outside the axis of rotation of and on an output shaft of said electric motor; and power source for said electric motor, said accumulator being rechargeab
