RU2540573C1 - Small-sized water-efficient urinal unit - Google Patents

Abstract

FIELD: personal use articles.

SUBSTANCE: urinal unit side and front walls are framed with a washing tube attached to the water source. The urinal unit contains a valve controlling water supply. At the water output from the valve a swage is installed. At the swage butt-end part, at a 3÷8 mm distance from each other, two parallel slots with a length equal to 3÷8 mm are made. The plate created with the slots is curved inside the swage in the form of an arch.

EFFECT: simplification of the design of an urinal unit efficiently using water for ablution.

Description

The invention relates to the field of sanitary engineering and can be used in the toilet rooms of residential, public and industrial premises.

Fresh water today can be considered an exhaustible resource, because in many regions of the world there is an acute shortage of water. Water resources are especially scarce in areas of maximum concentration of the population, industry and agriculture. Depletion of water resources is mainly due to pollution of water bodies by household, industrial effluents and agricultural washes. At the same time, of household water consumption, the largest consumption is for toilets. Based on the foregoing, saving water resources is currently one of the highest priorities, especially for areas with a shortage of water sources.

Known urinals made in accordance with GOST 30493-96 “Ceramic sanitary ware”, including wall with a completely molded siphon, equipped with standard drainage fittings and flush valve or other tap fittings.

The closest in technical essence analogue to the proposed small-sized water-efficient urinal is a toilet device adopted for the prototype according to patent No. 2377368, containing a urinal, the side and front walls of which are framed by a washing pipe attached to the water source, and having a valve that controls the flow of water for washing the urinal, moreover, the flushing tube has a plurality of sprinklers directing jets of water for flushing the urinal.

However, the known designs of urinals use a sufficiently large amount of water to wash them, and therefore are not economically efficient.

The objective of the invention is to develop a technical solution simple in design of a small-sized urinal, but at the same time more efficiently using water to wash it.

The technical result obtained by the practical use of the invention is to minimize the consumption of water from the water supply network for washing the urinal due to more efficient spraying of water along its front and side walls.

It is known that standard dual-mode toilets discharge about 3 or 9 liters of water at a time of use, then the claimed water-efficient urinal will discharge only ~ 0.3 ÷ 0.5 liters of water with a single valve actuation, and its operation is more convenient and ergonomic for the male part population.

The receipt of the specified technical result is based on the use of the effect of self-oscillating fluid flow. Empirically, it was found that the flows formed when air or water exit from rectangular openings blocked by arches, after flowing around the edges of the outlet openings under the arch, alternating compression of one flow by another occurs, which generates a breakdown of the vortex structures, leading to the appearance of a stable self-oscillating resultant flow directed alternately in different directions along the axis of the arch (See, for example, Avdeeva TP “Air distribution by dynamically unstable flows.” Thesis for the degree of academician of technical science - L .: S bGASU, 2001. - 360 s)..

The above technical result is achieved by using the inventive small-sized water-efficient urinal, the side and front walls of which are framed by a washing tube attached to a water source, and having a valve that controls the flow of water. At the same time, at the water outlet from the valve, a blind pipe is installed, in the end part of which at a distance of 3-8 mm from each other, two parallel cuts of 3-8 mm length are made, and the plate formed by these cuts is bent into the pipe in the form of an arch. The indicated dimensions of the arch are obtained empirically, and their specific size depends on the size of the bowl of the urinal.

In the particular case of the claimed device, in the lower part of the urinal, before its drain, a horizontal tide of 5–20 mm high was made, protecting it from splashing water outside (outside) of the urinal.

The invention is illustrated in the drawings (figure 1 ÷ 5), which shows the following projection of the claimed device (dimensions in the figures are given only to confirm the small size of the claimed device):

figure 1 shows a General view of a small-sized water-efficient urinal;

figure 2 shows a top view of the urinal;

Figures 3, 4 and 5 show three projections of a blind pipe with an arch.

The figure (figure 1) shows the cross section of the urinal with the neck 1 of the bowl of the urinal, water supply (inlet) pipe 2, valve (flush control) 3, pipe 4, at the bottom of which there are slots 5 (figure 5) and arch 6, outlet a pipe with a water lock 7 for drain into the sewer. At the bottom of the front wall of the bowl there is a tide 8. The figures (Figs. 3, 4, 5) show a blind pipe 4 with an arch 6 in various projections.

When valve 3 is activated, which can be either mechanical or automatic, a portion of water, measured by valve 3, from a preliminary storage tank or network (not shown) through a water supply pipe 2 enters pipe 4, in the dead bottom of which there is an arch 6, curved inside the nozzle 4, and through the openings of the arch enters the urinal bowl in the form of small drops due to the resulting self-oscillating resultant stream.

A small-sized water-efficient urinal can be equipped with both new and under construction residential or industrial premises, as well as retrofit toilet rooms in various existing rooms.

Thanks to the use of the declared water-efficient urinal, in addition to ergonomic amenities, water costs during the operation of the toilets will be significantly reduced, which is especially important in conditions of a scarce supply of water to the settlements in whose territory the claimed water-efficient urinal will be used.
