The invention relates to municipal engineering, namely to machines for washing and pressing drum type drum, and can be used in washing and washing and squeezing machines, washing line washing machines, drying machines, edge squeezing machines, dry cleaning machines as well as in the finishing production of light and textile industry and in other branches of the national economy.

The purpose of the invention is to improve the otstiraya

Fig. 1 shows a schematic machine diagram; Fig 2 is a section in Fig.1.

Inside the housing 1 of the washing machine, on the axis 2, there is a cylindrical perforated drum 3, which has a loading hatch 4 on the front end wall 5 and a solid rear end wall 6. On the inner cylindrical surface of the drum 3 there are ribs, each of which is the length of the rim and consists of local stubs 7, which can be made by stamping in one piece with the surface of the drum or in the form of individual parts and welded to the inner surface of the drum 3 Adjacent and the length of the drum 3 bulge 7 are separated from each other by a section 8 of a cylindrical surface. All convexities are arranged even 9 and odd причем rows, and convexities of even rows 9 are located between thicknesses 7 odd rows 10 in the diametral plane of drum 3, even 9 and odd 10 rows of convexes 7 are curved in a curvilinear fashion, with the angle of inclination of rows 9 and 10 of the protuberances 7 in relation to the generator of the drum 3 increasing in the direction from the loading port 4 to the rear end wall 6 as the height of the protuberances 7 decreases. tori 11 resting on the base 12. The drum 3 is driven by the electric motor 13,. installed on the housing 1, via a belt drive 14. The housing 1 is connected to the mains 15, through which detergents and finishing agents are fed into it, cold and hot water, steam.

The machine works as follows

The laundry to be processed is loaded through the hatch 4 into the drum 3. Through line 15, the body 1 is supplied with washing equipment, and the electric motor 13 is driven into rotation by the drum 3 through a belt drive 14,

During the washing process, as the drum 3 rotates, the laundry under the action of rolling protuberances 7 alternately bends, lifting up on the convexes 7 and falling between them. Erasable laundry partially slips along convexity 7. At the same time, under the influence of even 9 and odd 10 rows, the laundry is carried away from the bottom of the drum 3 into its upper part. When the direction of rotation of the drum is changed, the laundry falls on the surface of the protrusions, but on the other side, previously facing the center of the drum.

With repeated passage of rows 9 and 10 of larger constrictions 7., the underwear is repeatedly bent not only in the diametral plane of the drum 3, but also in a plane parallel to the axis 2 of its rotation, due to the passage of the linen on the 8 sections to the method of separately located 7 senses.

Under the action of curvilinearly curved rows 9 and 10 of the sleeves 7, the laundry during rotation of the drum is displaced in the direction of the axis of rotation 2 to one or the other m orc wall 5 or 6, depending on the direction of rotation of the drum 3. Moreover, the beacon is shifted to the rear end wall 6 is more active as a result of decreasing the height of the protrusions and increasing the angle o.

The detergent rounds the convexes during the rotation of the drum bar and, encountering a convex edeen, ejects them, forming numerous turbulent vortexes and pulsations under the influence of which the detergent foams actively All these factors contribute to the intensification of the washing process.

After the washing and rinsing is completed, the washing machine (washing-pressing) switches to the split mode: DKI. In the layout mode, before the machine exits the spinning cycle, the correctness of which largely depends. The machine’s vibroharacteristics depends, the drum 3 is rotated only in one direction , with the layout of the linen in the initial period carried out with water,

remaining after rinsing, and then after a certain period of time it is drained.

A uniform arrangement of the sleeves 7 on the surface of the drum 3 and a relatively small height improve the quality of the layout of the linen, reducing the level of vibration and increasing the reliability of the machine.

The quality of the layouts is also improved by increasing the angle of the rows 9 and 10 to the drum 3 forming as the height of the protuberances 7 decreases in the direction from the loading door 4, thereby improving the condition of the shift and the side of the rear wall 6 of the drum 3.

When concentrating the main mass of linen at the rear of 6 console console 3, the shoulder and the bending moment are reduced from the mass of the linen, which reduces the level of vibration and increases the reliability of the shop.

make a drum out of thinner material and reduce its material -. aloemkost A reduction in material consumption leads to a decrease in energy consumption, since a lower power motor is required to set in motion a lighter drum. Reducing the mass of the drum reduces its inertia and time for acceleration and deceleration. This further shortens the washing cycle and increases productivity.

Convexity can be oval, spherical or zllipsoid, cone-shaped with rounded tops and others.

In the proposed machine, as compared with the known, the productivity is increased due to the improvement in the availability of the beacon due to the increase in the mechanical effect from the training of the tension during rotation of the -drum and at the moment of reversal

After laying out the bel car, it exits, from an increase in the number of bends per

Diet spinning mode. During spinning, the shape of the loops 7 contributes to a reduction in the adhesion of the linen with the inner surface of the drum 3, because the lineway is pressed to one part of the surface by a convexity 7 directed to the direction of movement, the circumferential force, the air resistance force and moisture removed, and 7, in the opposite direction of movement, these factors separate the laundry. As a result, the force of adhesion of the laundry with the profiled surface of the drum is reduced. The bonding force of the drum with the drum 3 after spinning is also reduced due to the presence of alternating plastic deformations. contributing to the restoration of the original form of linen.

Reducing the force of adhesion of the laundry with drum 3 provides an improvement in the condition of its separation in the course of lining and shortens its duration. Due to this, the manual operation to separate the laundry from the surface of the drum 3 is eliminated and the washing cycle is further shortened.
