CZ20004198A3 - Circuit arrangement of automatic washing machine having pressure variable working chamber employing as washing medium water along with a mechanical washing process - Google Patents

Abstract

The principle of assembly of the automatic washing machine with a variable pressure working chamber using water as a washing medium in combination with a mechanical washing process lies in connecting of the pressure-controlled chamber (1) to the source of pressure (7) and the source of vacuum (8), both connected to the programmer (5). The realization according to the invention is suitable for washing of textiles and other materials of a similar texture in industrial and household washing machines.

Description

BACKGROUND OF THE INVENTION The present invention relates to an automatic washing machine having a pressure-variable working chamber using water as a working medium together with a mechanical washing process and which is applicable to both industrial and household washing machines.

BACKGROUND OF THE INVENTION

For washing textiles, textile products and articles made of similar materials, automatic washing machines using water as a working medium in conjunction with a mechanical washing process are widely used. The washed material is fed into the working chamber of a washing machine containing a water bath customarily supplemented with detergents, water softeners and flavoring agents forming the working medium. Mechanically, for example in a rotating spout, by means of a worm gear, a vibrating device or by ultrasound, the washed material is further free of impurities. During this process, the washing medium is heated at various times by an electric heater according to a pre-selected program by means of a programmer consisting of an electric or electronic control unit connected to the shut-off elements, drive unit, heater and other washing machine accessories. other specific user requirements. Depending on the set program, the mechanical process with the main drive unit operates at different time intervals and includes the transport of clean water to the working chamber and discharge of the working medium to the waste by means of a transport electric pump. drive unit. All of the above-mentioned appliances, power units and pumps, heaters and other washing machine accessories use the most electrical energy and show their energy intensity, which besides the choice of washing program is very difficult for the user to influence while maintaining the desired result of the washing process.

It is therefore an object of the present invention to provide such a washing system which minimizes the aforementioned energy performance to the extent necessary and is technically simple to implement and possibly applicable to existing washing machines.

SUMMARY OF THE INVENTION

The aforementioned drawbacks largely eliminate and the purpose of the invention is achieved by the connection of an automatic washing machine with a pressure-variable working chamber using water as the working medium together with a mechanical washing process consisting of a pressure-sealable chamber containing a mechanical washing mechanism with main drive. to a clean water supply and by means of a scrubbing waste element for a washing medium provided with a conveying pump, wherein all the sealing elements, the main drive, the conveying pump and the heater are connected to a programmer comprising an electronic control unit according to the invention; connected by means of multifunctional closing element to the source of overpressure and to the source of underpressure and wherein the pressure-sealable chamber is further connected to the programmer and by means of a strain relief shut-off with washing medium waste, and wherein the multifunction closure and the relief closure are connected to a programmer. The overpressure source and the underpressure source consist of a vacuum pump compressor integrated into the washing machine body and / or a pressure and vacuum distribution network.

DETAILED DESCRIPTION OF THE INVENTION

The schematic drawing shows schematically the main components of the circuit, in which a pressure-sealable chamber 1 is shown, in which a mechanical device connected to the main drive - not shown and formed in this case by a rotating perforated drum 12 - is connected. a clean water supply 9 and via a waste shut-off element 21 to a washing medium waste 10 which is provided with a transport pump 3. The pressure-sealable chamber 1 is connected via a multifunctional shut-off element 6 to a positive pressure source 7 and a negative pressure source 8 which can be either an integrated compressor by vacuum pump either into the washing machine body or by vacuum and overpressure distribution network. The pressure-sealable chamber 1 is further connected via the pressure relief element 11 to the washing medium outlet 10 and via a pressure gauge 4 to a programmer 5. All the closing elements of the connection, the conveyor pump 3, the source 8 ll. I iJii, lili mni i M'jl! HWJIII1) 1 ^| i ^{l 'l} l1l imBIIIIIII! l ^l l ^lll Imiimi south!'! ΙΙ! 1'Ί ^! Β ^! IIJ!

vacuum and overpressure source 7, heater - not drawn, main drive - not drawn and other washing machine control accessories are connected to the programmer 5 formed by the electronic control unit. The device operates in such a way that, according to the selected washing program by the programmer 5, individual washing modes are selected, which are supported by defined changes of overpressure and underpressure in the interior of the pressure-sealable chamber as well as in connection with closing elements corresponding to the given function. The relief valve 11 is installed in the event of an overpressure in the pressure-sealable chamber 1 and is set to a pressure limit value.
