Description

Field of technology

The ventilation system of a toilet bowl is applicable in everyday life and hygiene.

Prior art

A ventilation system for a toilet bowl with a lid is known, which includes the dish itself as such. It is ventilated with the lid raised, whereby the accumulated gases in it fall into the air in the room where the toilet bowl is located.

The disadvantage of this toilet ventilation system is that immediately after using the plate "in great need", the user, who during the use played the role of a lid, gets out of it, the most concentrated gases enter the air in the room where it is located. In addition, even when using the toilet bowl, the user, due to the topology of his body, closes with it only part of the opening of the toilet bowl, which is why, even during the use of the toilet bowl, the most concentrated gases fall into the air in the room where it is located. This disturbs the comfort in the room and the hygiene of the process.

Patent application GB 2292395 discloses a toilet bowl ventilation system which comprises a pot to which a lower rear opening for draining sewage and an upper rear opening for connection to a flushing water source by means of a pipe are provided. A tester is mounted to the pipeline, where one end of the air duct is connected to the free end of the tester. The other end of the duct is connected to the inlet of an autonomous fan, whose command signal input is capable of connecting an autonomous motion sensor. The disadvantage of this solution is the use of a tester to connect the pipeline and the air duct, which creates a complete interruption of the process of exhaust gases through the air duct during the discharge of water through the pipeline for flushing water.

There is known a solution of international patent application WO 1999/035349, which discloses a ventilation system for a toilet bowl, which includes a pot to which a lower rear opening for drainage of sewage and an upper rear opening for connection to a source of flushing water by means pipeline. Two additional ventilation openings are formed on the pot, symmetrically located on both sides of the opening for the flushing water source, respectively under the upper rear opening for connection to the flushing water source. The disadvantage of this solution is the location of the two ventilation openings under the flushing water opening, which creates a difficulty or complete interruption of the exhaust gas discharge through the ventilation opening during the discharge of water from the rinsing water opening.

From the registered utility model DE 201 08 033 U1, a ventilation system for a toilet bowl is known, which includes a pot to which a lower rear opening for drainage of sewage and an upper rear opening for connection to a flushing water source by means of a pipeline are provided. An additional opening is formed on the pot, to which one end of the air duct is connected, and the other end of the air duct is connected to the inlet opening of an autonomous fan, whose input for command signal is connected to a sensor. In the known solution, the additional ventilation opening is located below the upper rear washing water opening. To prevent water from entering the additional ventilation opening and to reduce the presence of significant obstructions in the exhaust, a cover is provided in front of and on the additional ventilation opening, which cover is located at a distance from said ventilation opening.

A disadvantage of the known solution is the difficult passage and removal of gases through the ventilation opening and the air duct.

Technical essence of the invention

The object of the invention is to provide a ventilation system for a toilet bowl, in which the discharge of gases through the ventilation opening and the air duct takes place without interruption and without any obstacles, and to prevent the entry of any amount of flushing water through the opening.

This task is solved by creating a ventilation system on a toilet bowl, consisting of a pot, to which are provided a lower rear opening for drainage of sewage, an upper rear opening for connection to a flushing water source by pipeline, at least one additional opening for ventilation located on the rear wall of the pot, in which is lowered the lower end of an air duct, the upper end of which is discharged into the inlet of an autonomous fan, the input of which for command signal is connected to an autonomous motion sensor. At least one additional ventilation opening is located above the upper rear flushing water opening

It is possible for the toilet bowl ventilation system to include an additional second ventilation opening located symmetrically with the first ventilation opening on the rear wall of the pot, above the upper rear opening for flushing water.

Description of the attached figures

In more detail, the ventilation system of a toilet bowl is shown in the attached figures, where: figure 1 is a side section of a ventilation system of a toilet bowl with ventilation through the upper opening for flushing water, known from the prior art;

Figure 2 is a side section of the ventilation system of a toilet bowl with ventilation through an additional opening in the rear part of the pot, located above the opening for flushing water;

Figure 3 is a rear view of the pot with an additional vent;

Figure 4 is a rear view of the pot with two additional vents.

Exemplary embodiment and operation of the invention

The ventilation system of the toilet bowl shown in Figure 2 and Figure 3 consists of the toilet bowl itself, whose pot 1 with a movable seat board 2 and a movable lid 3 with a common hinge and a lower rear opening 14 for drainage, upper rear opening 4 for connection to a flushing water source 6, preferably mounted on the wall 7 of the ventilation shaft 8, by means of a pipe 5. The pot has in its rear wall, at the level of its upper edge, at least one additional ventilation opening 13 located on the rear a pot wall in which the lower end of an air duct 10 is discharged, the upper end of which is discharged into the inlet of an autonomous fan 11, the input of which for command signal is connected to an autonomous sensor 12 for movement in the room where the system is located. At least one additional ventilation opening 13 is located above the upper rear washing opening 4.

The power supply of the sensor 12 and the fan 11 can be from autonomous sources or from the network (not shown in the figures).

As shown in Figure 4, it is possible for the toilet bowl pot 1 to have two additional openings 13.1 and 13.2 symmetrically located on both sides of the opening 4.

The ventilation system of the toilet bowl in Figure 2 works as follows. As soon as a person enters the room, the motion sensor 12 detects this movement and with its control signal turns on the autonomous fan 11, which begins to draw air through the additional opening 13 and the air duct 10 and discharge it into the ventilation shaft 8. This process continues while the toilet is also used during the most exhaust gases, which are thus not allowed in the room. The descent of the flushing water from source 6 does not interfere with the ventilation, as the ventilation system of the toilet bowl is designed so that the flushing water flows through an opening located below the ventilation opening, respectively there is no obstacle for the passage of gases through said opening. for ventilation and flushing water does not enter the ventilation opening 13.

For ease of installation, one of the additional holes 13.1 and 13.2 shown in Figure 4 is used instead of one additional hole 13. Then the unoccupied hole is closed with an additional cap (not shown in the figures). It is also possible to use both additional openings 13.1 and 13.2, with a second ventilation circuit (not shown in the figures) connected to the remaining free opening.
