Description

The invention relates to a toilet device with a vacuum system for removing feces from a toilet cabin both in transport and in an individual living environment.

Known toilet modules [1], [2] containing a toilet, a vacuum feeder of fecal wastewater with a pipeline and a valve in it, a receiver of fecal wastewater, a toilet cleaning device with a water tank.

The closest in technical essence is a toilet module [3], which contains a toilet bowl, a fecal sink receiver, a fecal line from the toilet to a fecal sink receiver with an unloading valve, a flushing device with a water pump, a vacuum apparatus connected to the fecal line, a controller .

The disadvantages of such a toilet module are its inconsistency with environmental requirements for the sound pressure level in the toilet cabin at the time the toilet contents are lowered into the faecal sink receiver, the excess volume of the vacuum system for transporting the toilet contents to the faecal sink receiver, and the excessive variety of controller functions.

The technical result of the invention is to minimize the sound pressure level in the toilet cabin and the productivity of the vacuum apparatus, reduce the functions of the controller, increase the reliability of the toilet module.

This technical result is achieved in the toilet module, which contains a toilet bowl, a fecal sink receiver, a fecal line from the toilet to a fecal sink receiver with an unloading valve, a flushing device with a water pump, a vacuum apparatus connected to the fecal line, a controller, so that a self-closing check valve installed between the fecal line and the receiver of fecal waste is introduced, made as a cylindrical thin-walled tube made of elastic material a type of rubber, in the middle part of which a recess is stamped, which is directed by its external convex part into the cavity of the tube with the possibility of completely overlapping the opening of the fecal line.

In one particular case, the outer surface of the convex part of the recess is made in the form of a part of a spherical surface, the radius of which is not less than the inner diameter of the fecal line, having a circular cross section.

In another particular case, a bypass is installed between the discharge valve and the self-closing check valve in the fecal line.

By introducing a self-closing check valve, the vacuum required to transport the fecal wastewater from the toilet to the faecal sink receiver is ensured only in the volume of the fecal line, which leads to a decrease in the volume in which a vacuum is required. Therefore, the environmental friendliness of the toilet module is increased due to the decrease in sound pressure in the toilet cabin as a result of the minimum air volume required for the transportation of fecal effluents in the space between the toilet and the faecal sink receiver.

Reducing the volume in which a vacuum is necessary, minimizes the performance of the vacuum apparatus.

As a result of the introduction of a self-closing check valve, a reduction in the functions of the controller is achieved, since there is no need for actuators requiring interaction with an unloading valve and a flushing device to actuate a self-closing check valve.

With the introduction of a self-closing check valve, the reliability of the toilet module increases due to a decrease in the number of actuators required for the functioning of the toilet module.

Bypassing the faecal line, the reliability of the toilet module is increased, since the possibility of overflowing the fecal line with fecal drains is eliminated due to the fact that there is no increase in air pressure in front of the moving stream that impedes the movement of the stream.

In Fig.1 shows a General view of the toilet module, Fig.2 is a view of a self-closing check valve, Fig.3 is a cross-sectional view of a self-closing check valve, Fig.4 is a view of a self-closing check valve in an open state, Fig.5 - view of the fecal line with bypass.

The toilet module (Fig. 1) contains a toilet bowl 1 located in the toilet cabin, a fecal waste receiver 2, a vacuum apparatus 3, a water pump 4, a controller 5 connecting the toilet outlet 1 to the faecal sink receiver 2 a fecal line 6 in which a relief valve is made 7 and a self-closing check valve 8. The water pump 4 is connected by a pipe 9 to a toilet 1 and a pipe 10 with a tank 11 with water. The vacuum apparatus 3 is connected by a pipe 12 with a fecal line 6 and a pipe 13 with an unloading valve 7, which can be actuated by supplying atmospheric air to it in series and creating a vacuum.

The self-closing check valve 8 (Fig. 2) is made as a cylindrical thin-walled tube 14 made of an elastic material such as rubber, in the middle part of which a recess 15 is stamped, which is directed by its convex part into the cavity 16 of the tube 14 and is located between the cavities 17 and 18 of the fecal line 6. In a preferred particular case, the outer surface 19 of the recess 15 is made in the form of a part of a spherical surface with a radius r not less than the inner diameter d of the fecal line 6 having a circular cross-section.

The configuration of the recess 15 (figure 3) is such that in a free state it completely covers the opening of the fecal line 6, excluding the communication between the cavities 17 and 18 of the fecal line 6 and providing a closing mode for the self-closing check valve 8.

In the deformed state (Fig. 4) of a self-closing check valve 8, the entire tube 14 together with the recess 15 takes a cylindrical shape in which the outer surface 19 of the recess 15 is aligned with the inner surface of the tube 14. In this case, the cavities 17 and 18 of the fecal line 6 are interconnected via the open cavity 16 of the tube 14, which corresponds to the opening mode of the self-closing check valve 8.

Bypass 20 (figure 5) is located between the discharge valve 7 and the self-closing check valve 8 of the fecal line 6.

The toilet module operates as follows. When the flushing device is activated (Fig. 1), for example, by pressing the button intended for this, the water pump 4 is started by the commands received from the controller 5, a portion of the water from the tank 11 is injected into the toilet 1 through pipelines 9.10, and the discharge valve opens 7 by creating a vacuum in it from the vacuum apparatus 3. Under the action of the vacuum created by the vacuum apparatus 3 in the volume of the fecal line 6 between the discharge valve 7 and the self-closing check valve 8, the fecal effluent in the form of a product is excreted Together with a portion of water for flushing in the form of a cork, moving along the fecal line 6, they acquire the necessary speed. After equalizing the pressure in the fecal line 6 with atmospheric pressure, the fecal wastes inertia continue to move towards the self-closing check valve 8. Under the action of the generated pressure, the self-closing check valve 8 is deformed in front of the moving stopper from the mixture of water and feces, so that the recess 15 in the tube 14 folds so that the outer surface 19 of the recess 15 is aligned with the inner surface of the tube 14 (figure 4). As a result of deformation, the tube 14 together with the recess 15 takes a cylindrical shape, fitting into the cavity of the fecal line 6 and connecting the cavities 17, 18 of the fecal line 6 with each other by means of the open cavity 16 of the tube 14. At the same time, the self-closing check valve 8 enters the opening state, providing drainage fecal wastewater to the fecal wastewater receiver 2. After closing the discharge valve 7 as a result of the presence of environmental pressure in the fecal line 6 after the discharge valve 7 and after self-closing I check valve 8 recess 15 takes its original form. Thus, the self-closing check valve 8 enters the closing state (Fig. 2), (Fig. 3), and the discharge in the fecal line 6 is restored. The toilet module is ready for a second cycle of interaction between the toilet 1 and the fecal waste receiver 2.

Since the controller 5 gives commands only to the water pump 4 and the vacuum apparatus 3, and the self-closing check valve 8 operates autonomously, the functions of the controller 5 are minimal, which increases the reliability of the toilet module.

When passing through the bypass 20 (Fig. 5), the plug from the bowel product with a portion of water, air flows through the bypass 20 from the self-closing check valve 8 towards the discharge valve 7, the pressure on the plug from the bowel product with water from the discharge valve 7 increases, increases the speed of movement of the cork and decreases the time of passage of fecal wastes from the toilet 1 to the receiver of fecal wastes 2. As a result, the clogging of the fecal line 6 is eliminated, and the reliability of the toilet module is increased.
