SU1505997A2 - Method of flushing linen in drum of centrifuge with vertical axis - Google Patents

Abstract

The invention relates to domestic machinery, can be used in household washing machines with centrifugal extraction of the products being processed and allows to reduce water consumption. The way to rinse the underwear is to put the textiles into the drum and spin them by centrifuging. After stopping the drum, water is supplied to it, the amount of which is set by calculating per 1 kg of water depending on the type of linen. At the end of the water supply, the laundry is kept in water for 30-35 s, and then squeezed out again. The described process is repeated cyclically to provide a standard rinsing efficiency indicator. 1 tab.

Description

The invention relates to household engineering, can be used in household washing machines with centrifugal Gimom machined products and is an improvement of the method according to the author. No. 1305217.

The aim of the invention is to reduce water consumption.

The process of gargling the drum in a centrifuge drum is carried out in the following sequence: after the textile products have been placed in the spin drum, centrifugation is carried out, the period of which is determined depending on the type of fabric according to the following relationship:

Where

t — centrifugation time, s;

K is a coefficient that teaches the type of tissue being treated;

 - centrifuge angular acceleration, rad / s.

Then, the centrifuge drive is turned off and the spin speed of the drum is quenched to zero. After the drum has completely stopped, water is supplied to it, the amount of which is determined from the following relationship:

O. qt,

where Q. - the amount of water supplied,

q - coefficient taking into account the type of fabric being treated, kg / kg; ha - the mass of the processed linen,

At the end of the water supply, the laundry is kept in water for 30-35 s.

Then the centrifuge is turned on again and the described process is repeated cyclically until the standard level of the rinsing performance indicators is reached. The centrifugal rinsing process is completed with a final spin cycle with a duration that ensures the residual moisture of the squeezed products, not exceeding the standard,

To experimentally substantiate the optimal amount of water supplied to substantiate,

PRI im p Rinse the cotton linen and synthetic fabrics in a drum for squeezing with a different amount of water supplied for rinsing. The average amount of water supplied in liters, the number of rinsing cycles, the average water consumption in liters, and the power consumption are measured.

The experimental data are summarized in the table.

As B1 from the table, the optimal amount of water supplied for the strip is A, 0-5, O kg, i.e. 2.0-2.5 kg of water per 1 kg of linen, and for synthetic fabrics, respectively, 3.0-4.0 and 1.5-2.0 kg of water per 1 kg of linen. When reducing the amount below the optimum magnification}, the power consumption during rinsing is economically inappropriate.

Based on the data in the table, it can be argued that the optimum dose of rinsing water is determined from the relationship:
