Abstract

FIELD: subjects of personal and house use; transportation.

SUBSTANCE: toilet device consists of the case with a seat and a cover, portable capacity, reactant capacity and the pump. The bowl with a washout ring is established in the case. In the reactant capacity the filter and the discharge union is established. Thereat the reactant the capacity is located between the bowl and portable capacity. The portable capacity is connected with the reactant capacity and the pump by two valves.

EFFECT: increase of operational adaptability to manufacture thanks to refusal of the clamping mechanism and from the fitting assembly of portable capacity with a bowl.

Description

The invention relates to the field of aviation technology, and in particular to the equipment of toilets, in particular to toilet devices, and can be used on aircraft, as well as on other vehicles.

Known toilet device ES 9156-7900-WEM. Operation manual for the Universal branch of Zhukovsky, which contains a housing, a seat with a lid, a bowl with a flush ring, a remote container with a docking unit, a slide gate and a pump.

The disadvantages of this toilet device is its low operational adaptability, since the bowl is docked with the remote capacity manually, and the slide gate, which opens and closes with force, does not provide complete sealing, there is a danger of chemical fluid entering the external environment, as well as the fact that the remote the capacity has to be transferred together with a pump rigidly installed on it.

The closest technical solution, selected as a prototype, is a toilet device according to patent RU 2100254, MKI B64D 11/02.

The toilet device comprises a housing, a seat with a lid, a bowl with a flushing ring, an external container with a docking unit, a pump, a clamping mechanism made in the form of a frame with stops and guides. The clamping mechanism provides mechanical docking - undocking of the neck of the remote tank with a bowl and a split valve that supplies fluid to the pump.

The disadvantages of the known toilet device are:

- complex clamping mechanism;

- low operational adaptability of the docking station;

- the use of a centrifugal pump (instead of a self-priming) complicates the design, dimensions and weight increase;

- the supply valve strongly protrudes beyond the dimensions of the tank, which impairs operational manufacturability;

- when undocking, part of the chemical fluid enters from the plug valve into the external environment.

The problem to be solved by the alleged invention is aimed at: simplifying the design by rejecting a complex clamping mechanism or an unreliable slide gate; the use of design solutions that allow the use of both self-priming and centrifugal pumps, without changing the design of the device; refusal of the docking unit of the remote capacity with the bowl increases the reliability of the toilet device.

The technical result is achieved by the fact that the toilet device, consisting of a housing with a seat and a lid, with a bowl fixed to it with a flush ring, a remote tank and a pump, is equipped with a reagent tank with chemical liquid, with a drop drain fitting installed in it, and located between the remote tank and bowl, while the remote tank is connected to the reagent tank and the pump with two easy-disconnect small-sized valves.

A comparative analysis of the invention with identified analogues confirms that the proposed toilet device is new. The whole set of features of the present invention does not follow for experts explicitly from the prior art, therefore, the claimed device meets the criteria of an inventive step and is industrially applicable, since it allows to achieve a technical result.

The invention is illustrated by drawings, where:

- figure 1 shows a toilet device, front view;

- figure 2 shows a toilet device, a top view;

- figure 3 - section aa - depicts an easily disconnected small-sized valve.

"Operation manual" - a copy of the analogue is attached.

The toilet device consists of a housing 1 with a seat 2 and a cover 3, in which a bowl 4 with a flushing ring 5 is installed. The bowl 4 is connected rigidly to the reagent tank 6 by means of a drain neck. A filter and a drain fitting 7 are installed in the reagent tank 6, which recedes from the bottom by 1/2 the height of the reagent tank 6. The drain nozzle 7 can be lowered to the bottom of the reagent tank 6 using the lever 8. A flexible hose is fixed to the drain nozzle 7 at one end. 9, at the other end of which an easy-disconnect small-sized valve 10 is installed. An easy-disconnect small-sized valve 10, consisting of a spring-loaded nut 11 and a spring-loaded shutter 12, is installed in the remote tank 13. When tightening the spring-loaded nut 11 opens a spring-loaded shutter 12 in the remote container 13. The external container 13 is installed under the bowl 4 and the reagent tank 6, the chemical fluid flows from the bowl 4 by gravity into the reactant tank 6, then through the filter, drain fitting 7, flexible hose 9 and through an easily disconnected small-sized valve 10 v remote tank 13. The portable tank 13 is connected through an easy-disconnect small-sized valve 14 of the same design as the easy-to-open small-sized valve 10 and a flexible hose 15 with a pump 16. The pump 16 is mounted rigidly in the housing 1 and is connected to the flush ring 5.

The operation of the device is as follows.

A clean remote tank 13 is installed in the housing 1. Easily disconnected small-sized valves 10, 14 are installed in the remote tank 13. Chemical liquid through the cup 4 is poured into the reagent tank 6 and the remote tank 13 (or the chemical liquid can be poured into a clean remote tank 13 and when the pump is turned on 16 enter the reagent tank 6). When the pump 16 is turned on, the chemical fluid flows through the flushing ring 5 through the flushing cup 4 and enters the reagent tank 6, where part of the chemical fluid remains to dissolve the waste, and the other part is drained through the filter, the discharge nipple 7, the flexible hose 9, and the easily disconnected small-sized valve 10 into the remote tank 13, without overflowing the reagent tank 6. From the remote tank 13, the chemical fluid flows through an easily disconnected small-sized valve 14, a flexible hose 15, then to the pump 16 and through it to flush the cup 4. To remove the remote tank 13 but undock the easy-disconnect small-sized valves 10, 14. In this case, it is possible to completely drain the chemical liquid from the reagent tank 6 by lowering the discharge socket 7 with the lever 8 to the lower level, and after the liquid has been completely drained, the drain socket 7 will rise to the working level. Thus, the use of reagent tank 6, rigidly connected to the cup 4 through the neck, eliminates the need for a docking unit and a complex clamping mechanism, which is replaced by a docking-undocking system with two easily disconnected small-sized valves 10, 14 with a remote tank 13, and as a result, the reliability of operation increases and operational manufacturability of the toilet device.

The present invention is made at the design stage, working drawings are issued.
