Description

The invention relates to technical solutions for laundry services, in particular to devices for washing, drying and sterilizing textiles.

A vacuum washing machine is known (RF Patent No. 2144586. MPK D06B 17/00. [Text] Vacuum washing machine, patent holder Maklashov V.A. application No. 98117832/12, prior. 09.28.1998 publ. 01.20.2000. Bulletin 2) [1], intended for washing clothes in boiling washing liquid at a temperature below its boiling point at atmospheric pressure. It consists of a housing, inside which a tank, a drum, a vacuum pump, a condenser, a control valve and a pipeline are fixed. The disadvantages of the prototype are that, due to the design solution, the author only proposed washing textiles in a vacuum, and drying textiles is carried out in the traditional way.

The technical objective of the invention is to improve the technical performance of the apparatus by making it possible to accelerate the drying and sterilization of textiles without the use of additional devices, reducing the duration of washing and saving energy resources.

The technical problem is solved due to the fact that the machine for washing, drying and sterilizing textiles at a special-purpose facility consists of a housing, a control unit, a tank, a drum, an electric motor, a vacuum pump, a pump pump, a receiver, and is characterized in that the housing is made of composite material, wall thickness 2 mm, inside which a control unit is rigidly fixed, connected through a bus with an inlet valve, a water level sensor, a tubular electric heater, an electric motor, a pump, an ultraviolet lamp, a vacuum pump, a receiver, and a pressure sensor, as well as The ultraviolet lamp is fixedly fixed on the inner rear wall of the tank, connected through a vacuum air duct to a vacuum pump and a receiver, inside of which a condenser coil and a pressure sensor connected to a reducing pressure outlet valve are fixedly fixed.

The essence of the technical solution is to create a vacuum in the tank and during the process of spinning and drying textiles by irradiation with ultraviolet radiation, as well as to propose design solutions that make it possible to reduce the duration of drying and sterilization of textiles.

The apparatus for sanitary treatment of textiles consists of a housing (13) (optionally, made of composite material, wall thickness 2 mm, ensuring strength during operation under vibration conditions) inside which an electric motor (6) and a vacuum pump (10) are fixedly fixed. Electric motor (6) (as an option, brand DC31-00002 (Electric motor [Electronic resource] https://radugard.ru/elektficheskij-dvigate\l-dlva-stiralnoy-mashine-DC31-00002) [2], via a belt drive (14) is connected to the drum (7) through the coupling (23) and ensures its reverse rotation at various speeds. The drum (7) is rigidly and movably fixed inside the tank (3). On the outer upper side of the housing (13) the control unit ( 1), (optionally consisting of a microcontroller into which a program is embedded for various types of fabric and the degree of their contamination). It controls all technological processes of washing, spinning, drying and sterilizing textiles. Tubular electric heater (5) (optionally, brand DC47-00006X ([Electronic resource] (https://zipm.ru/goods/815870-nagrevatelniy-element-ten-dliy-stiralnoe-mashine-164940242965321568) [3], rigidly fixed in the lower part of the tank (3), connected through the bus (22) with a source of electricity. Vacuum pump (10) (as an option, brand DC31-00180A) (Vacuum pump [Electronic resource] https://radugard.ru/vakuum-nasos-dlva-stiralnoe-mashine -maxx- m50) [4], fixedly fixed in the lower part of the housing (13), connected through a vacuum air duct (15) with a tank (3) and a receiver (11), filled with water used for rinsing textiles. The receiver (11) is connected through a pipeline (18) to a reduction pressure outlet valve (24) and a sewer pipe (19). Ultraviolet lamp (9) (as an option, brand AquaPro UV-SL) (Ultraviolet lamp [Electronic resource] https://radugard.ru/ULTRA-FIOLETLAMPA) [5], hermetically fixed in the rear wall of the tank (3), connected through bus (22) with control unit (1). A damper pad (17) is rigidly fixed on the lower part of the leg (16) (optionally, made of compensation material, rubber with a density of 1200 kg/m ³ ), which reduces vibration impacts on the structural elements of the device (RF Patent No. 201839 IPC F16F 7/00 [Text] Device for reducing the influence of vibration and shock effects on the performance of technological equipment, patent holder Romanchikov S.A., Popenyuk D.I., application No. 2020132900, priority 10/06/2020 published 03/17/2001 Bulletin 8 [6].

The apparatus for sanitizing textiles works as follows. Textiles are loaded into the drum (7). Depending on the type and degree of contamination, the washing program is selected.

The water entering the tank (3) ensures the process of soaking textiles. During the rotation of the drum (7), due to the centripetal force, textile products actively collide with the internal ribs of the drum (7), as a result, dirt is knocked out of the fibers of the textile products. The duration and temperature conditions for washing textiles depend on the selected washing program when starting the machine. Rinsing of textiles is carried out in a drum (7) with a rotation speed of 50 - 70 rpm for 5-7 minutes. During rinsing, detergent residues are washed out of textiles. Textiles are spun in a drum (7) with a rotation speed of 400-1200 rpm for 15 minutes. With the start of spinning textiles, the control unit (1) sends a command to the vacuum pump (10) which creates a vacuum with a pressure P = 289 Pa in the tank (3). Drying of textiles is carried out due to the synergy of effects from the centripetal force of rotation of the drum (7) and the vacuum in the tank (3) (Amosov V.I. Vacuum drying of clothes [Text] Physical processes. - 2016. - No. 4. - P. 55 - 59) [7], which ensures the evaporation of water molecules from the fibers of the fabric during its boiling (t _boil = 75°C) at a pressure inside the drum P = 289 Pa. A tubular electric heater (5) raises the temperature inside the tank to 75°C. The pressure in the tank (3) is controlled by a pressure sensor of the vacuum pump (20), fixedly installed in the inner surface of the tank (3), in the inner part of the vacuum air duct (15). The evacuated moist air from the drum (7) is supplied through a vacuum air line (15) to the condenser coil (21) of the receiver (11). The receiver (11), 1/3 of the volume filled with cold water (t = 15°C), ensures condensation of water vapor (t _boil = 75°C) in the condenser coil (21), coming from the tank (3). During the injection of moist air into the receiver (11), the level of air pressure and water level increase. Removal of water and air from the receiver (11) is carried out into the sewer pipe (19) of a special-purpose facility through the release valve of the reducing pressure (24), to atmospheric pressure, through the pipeline (18).

Sterilization of textile products is carried out at the stages of spinning and drying, due to the radiation of an ultraviolet lamp with electromagnetic waves that have a bactericidal effect (λ = 210 nm), which ensures its sterilization from microorganisms, viruses and insects, and from linen lice. Sterilization of textiles with ultraviolet radiation is carried out during the spinning process minutes, as well as during the drying process of textiles minutes (Borisov L.B. Medical microbiology, virology and immunology. - MIA, 2005. - P. 154-156. - ISBN 5-89481-278-X) [8].

Experimental studies carried out on the basis of Proektintertekhnika LLC using a pilot sample of an apparatus for sanitary processing of textiles allowed us to obtain the following results:

the use of ultraviolet radiation in the process of rinsing and drying textiles ensures sterilization from microorganisms, viruses, insects, lice, mites and their destruction up to 90% (Fig. 3);

design solutions of the device provide 90-12% energy saving (Fig. 4);

the technical solution makes it possible to reduce the duration of the technological cycle for processing textiles (washing, rinsing, drying) from 45 minutes to 41 minutes (Fig. 4);

the use of vacuum accelerated the drying of textiles by 20% to their humidity W = 5 - 8%, which eliminates additional drying outside the apparatus.

Thus, the apparatus for sanitizing textiles is new and provides improved technical performance by enabling accelerated drying and sterilization of textiles without the use of additional devices, reducing washing time and saving energy resources.
