Abstract

By way of realization of opportunities of a new way of washing of linen with help bubble the activator allowing to fully automate all process of processing of linen without any participation of the consumer from a bookmark before drying with an opportunity of direct connection to any of known ironing installations, it is offered two new variants of designs of SM for full processing linen in weight up to 5 kg distinguished from earlier suggested designs by application of special less labour-consuming and more simple units with overlapping of functions, that, besides reduction in price of manufacture, has allowed to reduce even more weigt, dimensions and the charge of a liquid.

Description

Household machine for complete processing of linen.

Description.

Considering the possibilities of modern CMs, despite the impressive number of improvements in their structures, you are convinced, even without a special analysis of their operational and technical features, that they are predetermined by the washing methods used.

These ways of conducting the washing process in a common heap without taking into account the characteristics of each thing separately and predetermined insurmountable difficulties for combining all stages of washing into a single process of complete processing of the laundry up to ironing without any consumer intervention.

A new method of washing, devoid of this disadvantage, was proposed by the author in the patent of the Republic of Latvia JNb 13245 dated April 20, 2005, where fabric items are laid in CM or in the form of packages (folded in several layers of sheets, etc.) up to 1 thick, 5 cm and a width of up to 35 cm, or neatly laid out on the receiving panel at the entrance to the CM items of clothing of similar sizes, except for products made of leather, plastic and rubber. This allowed the use of a bubbling activator that allows the passage of an airborne (MP) flow of MP or water (with cavitation at the time of pressure drop in the flow) through the tissue moving along the open cavity of the activator between 2 conveyor perforated belts from one storage roller to another, and after removing the liquid and pressing the fabric, use the ability of the activator to push dry air through the fabric with the suction of the moistened one and thereby carry out effective drying. Connecting to such a CM any of the known ironing plants is not difficult, which will ensure the continuity of the complete processing of linen.

In practice, this method of processing linen showed the possibility of eliminating almost all the drawbacks inherent in all types of modern CM drum, activator and vibration performance, namely: a) the impossibility of continuously conducting a full cycle of laundry processing in automatic mode. b) the need to sort linen and the inconvenience associated with the definition and installation of a wash program for each group depending on the type of fabric. c) crushing and tangling of linen. d) the necessity of hanging the undressed linen for hanging down and completing drying outside the CM. e) lack of cost-effectiveness of CM in the cost of time, water, detergents, electricity, especially with incomplete loading of CM. e) noise, vibration. ι g) considerable weight. h) the impossibility of the automatic withdrawal of linen after processing in the drive or ironing device. i) almost no variety of sizes and shapes of CM of one class. K) the lack of automatic selective effects on different types of tissue. l) lack of measures against the ingress of allergic suspensions into the air when filling CM with detergents. m) the inability to use any drive other than electric.

The results of the search by an international CM development agency in US-2,885,877A, US-1,466397A, US-4361018A, US-4159632A and US-1568240A, which are also not resolved by these search problems. However, in part of the CM refinement according to para. d, f, s, u, k, l, and m remains one or the other for worries to improve these characteristics. Therefore, new versions of CM designs with a modernized bubbling activator (Fig. 1-1) are proposed, in which the inlet and outlet valves (36) fig. 1-4, in combination with shut-off valves (P and E) fig. 1-2 allow to exclude the distribution device in the pneumatic system, to solve the issue of automatic control of the impact on the fabric depending on its thickness (density) and to ensure water saving by the bypass system in the process of washing and rinsing, which corresponds to solving the problems according to p. d, w and k. Input device in Fig. 1-5 is a dispenser for the supply of detergent and water, depending on the thickness and amount of fabric, which simultaneously solves the question of the processing time as per pp. d and l. For example, CM designed for 5 kg of linen, for example, can be used for washing 1 kg or 2.5 kg of linen with the resources reduced accordingly by 1/5 or 2.5 / 5 of the amount spent on this amount of linen. For a more reliable and controlled sealing of the activator cavity during membrane oscillation operating cycles, jogging advancement of linen is applicable with tight binding of the entire sealing time with the conveyor belts stopped for the duration of the activator membrane cycles. In addition, by combining the functions of the membranes located one below the other activators, there is no need for special baths under them, replaced by a common pan (2), from which excess washing solution or water by the pump (18) is fed directly into the cavities of the activators through the holes in their base. When processing laundry of indefinite forms (eg, bras, etc.) to avoid shunting jerky pressure on the open portions of the conveyor belt in the cavities of the lower activators, it is possible to place either a spongy elastic band with transverse capillary holes or between two lattice plastic planes between which spherical recesses in a single layer are light balls the size of a pea .. It also reduces the sag of conveyor belts and the load on them and the lower membrane of the activator, reducing the number and ytochny weight liquid. Work CM. The linen is laid in the side opening, captured by the upper (4a) and lower (46) conveyor belts on the driving rollers (Over) and the receiving coils (36), driven by a chain drive and sprockets rotating through a pulley from a reversing electric motor (5) . After winding up the pre-moistened laundry on the left-hand coil (36), the limit switches are activated, controlling the relays Pl and P2, which switch the reverse of the electric motor (5). When winding from the left coil (36), the laundry is reached by the activator (8c), pressed by the roller (15) and rinsed with activators (8b, a). When winding the laundry on the right spool (36), it is pressed on it by braking the tape with the spool (10), as well as with another pinch roller (15). By triggering limit switches Ki and Ki 'laundry starts to move in the reverse direction for drying, hot-air dryer (16), entering through a duct (20) and valves Kla _s in the upper activator in the upper stroke position KIIIM and valve Kla _2, the lower activator, and moistened air through Klbi and Klb _{2 by} exhaust (13) is removed to the air exchange system of the premises.

Another version of the CM design contains a new kind of bubbling activator and a device for rinsing. The activator consists of two plates of solid material with a thickness of 25 ÷ 30 mm and dimensions of 400x400 mm, facing each other with mirrored lines, where two groups of grooves alternate between each other, but not connected with each other (29), fig. 2-3, to which either the pressure or the vacuum (40) of fig. 2-3 from receivers (32) fig. 2-3 with pumps connected to them (60) fig. 2 pressures and dilutions, so that when these plates are mixed and diluted in the well-moistened fabric between them, a necessary bubbling process is formed, and when the wetting and spinning of the fabric is stopped, it is dried. In order to increase water saving during rinsing (this process is usually performed by two or three times changing water), a rinse is proposed, which is a case of two hermetically fitted halves, at the junction of which there is a through channel 15 mm high and 350 mm wide for passing conveyor belts with linen, moreover, at the left edge of the upper half there is an entrance slit (58) at the top of fig. 2-4 5x350 mm in size for wetting the fabric with water from a tank located in the upper part of CM, which, passing from top to bottom through the fabric, flows into the canal of the lower half of the pencil case through the same slit and represents a cavity with an internal diameter of about 5 mm and abutting from the bottom into the fabric and feeding the liquid into the slot of the exact same tubule in the upper half of the can and so several times, with the bends of the tubules in the upper and lower half (59) fig. 2-4 are made of rubber capable of without disturbing the tightness due to vibrations up and down from the KIIIM rods with a frequency of about 1 Hz during their out-of-phase movement, push the water and thereby more fully utilize the phenomenon of particle transfer in a liquid due to diffusion, thermal conductivity and viscosity. The main nodes in Fig. 1 and 2 have the following positions: 1 - body, 2

- bath, 3 (a and b) - lead roller, 4 (a and b) - conveyor belt, 5 - electric motor, 6 - gearbox, 7 - crank motor (booms), 8 - activator, 9 - spring, 10

- guide rollers and rupture rollers trans. tape, 11 - software device, 14, 15 - bracket with squeezing roller, 16 - hairdryer, 17 - drain valve, 18 - pump, 19 - damper, 20 - air duct, 23 - heating tank with heating elements, 24 - tank, 25 - pins, 26 — elastic activator body with a solid base, 27 — branch pipe, 47 — membrane, 48 — washing powder package, 49 — powder feeding screw, 50 —perforated membrane, controlled by the fabric thickness tracker, 51 — screw feeding spring into the package, 52 - auger of displacement and mixing of a dose of powder, 53 - axis of the screw, 54 - solution bypass hose, 55 - water make-up neck, 56 - gear and 57 - fabric softener, 58 - water inlet slit 59 - Rubber knee tubules, 60 - pumps. It has been experimentally established that in 5-6 cycles of 5 kg of circulation it becomes dry. The output from the CM occurs when the valve (19) is triggered; with the help of suckers on the hinges the laundry is loaded into the basket.
