Description

[Technical field]

[0001] The present invention relates to a toilet cavity ventilation system which can also be used to ventilate an individual toilet or bathroom space. [Background technology]

[0002] A ventilation system mounted inside a water tank is known from US 2002194670, which includes an odor drain from the toilet for extracting dirty air from inside the bathroom, an automatic flushing device, and a steam and moisture vent from the bath or toilet with an engine and a fan connected to the odor drain. The system consists of an inverted U-shaped outlet connected to the tank outlet and a passage arranged at the bottom of the tank, which leads to the outside of the tank and to which a fan is attached.

[0003] Another system for ventilating toilet containers, as described in WO2011153637, consists of an adapter that is attached to the inside of the water tank and is composed of two open chambers at the bottom that communicate with each other through a window, the lower part of the two chambers being located below the water level in the tank.

[0004] From Romanian patent specification 130981 B1 a ventilation system is known which uses the discharge path of a drainage circuit from a tank in the reverse direction using a fan located at the end of the discharge path, the system being formed in an output variant from a sealed chamber having two pairs of holes arranged on a vertical axis, through which pass several cylinders in which several pistons connected to each other slide, the cylinders having corresponding windows between them.

[0005] These ventilation systems imply major changes in the aquarium drainage assembly, unnecessary extraction of air and aquarium, as well as the ingress of water flow into the ventilation circuit or reverse air circulation when the fan is not operating. [Prior art documents] [Patent documents]

[0007] The technical problem that the present invention solves is the efficient ventilation of toilets, toilet cubicles and bathroom cavities. [Means for solving the problem]

[0008] The ventilation system according to the invention solves the proposed problem and consists of a ventilation device for the cavity of the toilet bowl, which is installed between the water tank and the drain pipe or inserted into the drain pipe, ventilation pipe. The ventilation device consists of a main body and a sub-body, a cylindrical protective part of the air circuit movable shutter installed inside the main body, and a movable shutter placed inside the main body and connected by a threaded rod and a nut of a stopper at the top of the float, the drainage of all water from the tank is prevented by a counterweight, the discharge of dirty air from the toilet is carried out by several radial windows formed in the main body, at the top of the air circuit a T-corner is arranged with an access cover for periodic sanitation of the dirty air circuit, a fan is installed in the piping and in order to better ventilate its housing, two end spacer rings and several windows formed in the piping in front of the fan are used, and at the circuit air outlet a lane flap is installed that prevents air from flowing back when the fan is not working.

[0009] In the following, examples of implementations of the invention are also presented in relation to FIGS. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The toilet bowl cavity ventilation system according to the present invention comprises a toilet bowl cavity D ventilator, a vacuum exhaust pipe 22 and a fan 23.

[0012] The ventilator D can be mounted directly on the tank R between the water tank and the drain pipe, or the ventilator D can be mounted and inserted onto the drain pipe by cutting the drain pipe, thus without dimensionally modifying the drain assembly.

[0013] The ventilator D consists of a cylindrically shaped body 1 installed coaxially inside a sub-body 2, which may be circular or square or of any other shape, as shown in FIG.

[0014] A fixed cylindrical protective part 4 is attached to the top of the main body 1, forming a common body with the main body 1 inside. The protective part 4 has the same external shape as the movable shutter 3 of the air circuit, which is arranged in the center of the main body 1. The cylindrical protective part 4 prevents the flow of water from the R tank from pressing the movable shutter 3 and moving it downward together with the entire water actuator, thereby stopping the leakage circuit from the R water tank.

[0015] In the middle part of the body 1, several radially located windows are made for the passage of dirty air and its exit on the ventilation circuit. The radial windows a have a height lower than that of the movable shutter 3, and the sub-body 2 is fixed externally in front of them. This allows the dirty air to be extracted radially through all the windows a, so that the result of the radial pushing force acting on the 3 slide is zero and the movable shutter can move and function without friction with the walls of the body 1.

[0016] The movable shutter 3 is connected at both ends by a threaded rod 6 passing through the center of the protective part 4 and a stopper 5 fixed at both ends by nuts 27. The stopper 5 is located at the upper end of the float 9, to which a counterweight 10 is attached to the lever of the actuator drainage system flap 7, consisting of a flap arm 8 and a support 11.

[0017] The weight of the mobile system attached to the float 9 prevents all water from being drained from the tank R. This problem can be solved by a dimensioned float 9, or by a counterweight 10 attached to the lever of the drainage system flap 7 according to FIG. 6, or by a pulley 14 simply fixed by supports 13 to the wall of the pool 12 of the tank R, above which a pulley is fixed on one side of the wire 16a to a counterweight 17 corresponding to the weight of the entire auxiliary system, and on the other side via supports 18 and a tip 19 on the float 9, according to FIG.

[0018] A T-corner 20 is fitted at the top of the air circuit with an access cover 21 for regular sanitation of the dirty air circuit.

[0019] There are cooling ventilation windows 24 along the fan 23 and two end spacer rings 25 are used for better ventilation of the fan housing 23, while an inverted flap 26 is installed on the exhaust circuit to prevent air from flowing back when the fan 23 is not running.
