Description

The claimed technical solution relates to electromechanical devices that remotely control the supply of water from the flush tank to the toilet bowl of the bathroom without the application of physical effort, the use of which can be carried out, first of all, in public toilets by a wide, often unlimited, circle of people.

The closest technical solution (prototype) is a device (RF patent No. 45413, E03D 5/00, publ. 10.05.2005 Bull. No. 13), containing a control unit with a processor board, a remote presence sensor, an electromechanical drive, a stem lifting element.

The disadvantages of the prototype: reduced performance due to:

1) the presence of a non-compact (sufficiently large) round box, in which the main control elements of the device are located, fixed on the lid of the drain tank (outside the case) and protruding above its surface;

2) making the water drain controls separate, i.e. the control unit and the presence sensor are each made in its own housing;

3) the presence of a mechanical handle, made separately and protruding from above the plane of the round box and activated by lifting up, prevents the user from bringing the palm of the hand to the presence sensor;

4) increased likelihood of damage to the round box of the flushing device by multiple users of public toilets, because it protrudes significantly above the surface of the drain tank;

5) the absence of a light indication in the device for: informing the user about the operation of the drain device; displaying various modes of the state of the drain device; the ability to control modes of operation;

6) the implementation of the stem control element from a metal tape, reduces the compactness, flexibility and durability of the stem lifting mechanism, and corrosion of the metal tape is also possible.

The technical problem solved by the creation of a new device is that a modern person, when visiting public toilets, risks getting a number of infections, including coronovirus infection (COVID-19), influenza, hepatitis A, salmonellosis, helminthiasis, viral conjunctivitis, dysentery, giardiasis, etc. ., which are transmitted through dirty hands (fingers). All this happens because the operation of the cistern in public places is controlled by applying physical force to the structural element of the drain mechanism, which is inhabited by pathogenic bacteria that can live even up to 48 hours. Therefore, the use of the proposed electronic device with a contactless remote start, installed as attachments on the toilet flush tank, will allow remotely, contactlessly, to bring the mechanism of the drain device into working condition, excluding the transmission of infectious diseases from a sick person to a healthy person, to combat the spread of which the state spends a lot of money. Also, the need for physical pressure on the flush mechanism of the toilet cistern when children, the disabled, the elderly visit the bathrooms of public places and at home often leads to some inconvenience due to a difficult task. Regular sanitization of public sanitary fixtures during operation requires a significant amount of water and human resources.

The technical result of the claimed utility model is the creation of an improved device with improved operational and technical characteristics.

The technical result is achieved by the fact that an electronic device for contactless remote control of the flush tank mechanism, containing a control unit with a processor board, a remote presence sensor, an electromechanical drive, a stem lifting element, moreover, a control unit with a processor board containing a remote infrared presence sensor and a light indication, a light filter located above the processor board, the pusher, made under the control unit with the processor board, and the elastic element mounted on the pusher, are made in a single module, located vertically in the opening of the drain tank cover, the electromechanical drive with the switching board is made rigidly fixed to the drain tank fittings, and the stem raising element is made in the form of a polyamide thread wound onto the drum. At the same time, a single module with its lower part is installed with an interference fit in a polyurethane sleeve located in the upper part of the drain tank fittings. In this case, the device can be configured to remotely control the drain from IR commands coming from external devices.

New essential distinguishing features of the proposed technical solution are the following features:

a control unit with a processor board containing a remote infrared presence sensor and a light indication, a light filter located above the processor board, a pusher made under the control unit with a processor board, and an elastic element mounted on the pusher are made in a single module;

a single module is located vertically in the opening of the drain tank cover;

the electromechanical drive with the switching board is made rigidly fixed to the drain tank armour.

The totality of new essential distinguishing features, along with the features known from the prior art, is sufficient to solve the specified technical problem and obtain the technical result provided by the utility model - improvement of the device with improved operational and technical characteristics.

The electronic device for non-contact remote control of the cistern mechanism (hereinafter referred to as the device), shown in the drawing, contains a control unit 1 (Fig. 1, 4) with a processor board that contains a remote infrared sensor 2 (Fig. 4) presence and light (multi-color) indication (LEDs) 3, light filter 4 (Fig. 1, 2, 4) located above the processor board, pusher 5 (Fig. 1, 4) of a three-stage cylindrical shape, located under the control unit 1 with the processor board, elastic element 6, mounted on the pusher 5, are made in a single module (button case) 7 (Fig. 1, 3, 4) for controlling the discharge of water into the toilet, i.e. all of these elements are built into a single module 7 (button body).

Light filter 4 (Fig. 1, 2, 4) consists of two plates made of milky white and infrared transparent acrylic. The combination of light filter plates 4 is designed to scatter the light coming from the light indication LEDs 3 (Fig. 4) and unhindered penetration of infrared radiation to the remote infrared presence sensor 2.

The elastic element 6 (Fig. 1, 4) is made in the form of a spring located inside a single module 7 (Fig. 1, 3, 4), designed to return the pusher 5 (Fig. 1, 4) to its original position when the filter is physically actuated 4 (Fig. 1, 2, 4).

A single module 7 (Fig. 1, 3, 4), the body of which is made of plastic, is located vertically in the opening of the cover 8 (Fig. 1, 2, 3, 4) of the drain tank 9 (Fig. 1) and is installed with its lower part with interference into the polyurethane sleeve 10 (Fig. 3, 4), located in the upper part of the armature 20 (Fig. 1, 3) drain (ceramic) tank 9 (Fig. 1).

Inside the body of the drain tank 9 there is a valve 20 (Fig. 1, 3) and an electromechanical drive (motor with a gearbox) 12 (Fig. 3, 4) with a switching board. The electromechanical drive 12 with the switching board is rigidly fixed to the plate 11 (Fig. 1, 2, 3, 4) attached to the valve 20 (Fig. 3, 4) of the drain tank 9 (Fig. 1).

The electromechanical drive 12 (Fig. 3, 4) is designed to open and close the drain hole 13 (Fig. 1) of the cistern 9 of the toilet bowl. The electromechanical drive (motor with gearbox) 12 (Fig. 3, 4) with the switching board is splash-proof.

Plate 11 (Fig. 1, 2, 3, 4) fastening the drive is located under a single module 7 (Fig. 1, 3, 4) - in the upper part of the valve 20 (Fig. 1, 3) of the drain tank 9 (Fig. 1) .

A thin thread 14 (Fig. 1, 2, 4) made of polyamide, wound on a drum 15 (Fig. 3, 4), is an element of raising (raising function) of the rod 16 of the armature mechanism 20 (Fig. 1, 3) of the drain tank 9 ( Fig. 1).

A single module 7 (Fig. 1, 3, 4) has a low rounded "hat" 17 (Fig. 1, 2, 3, 4), which in the assembled state of the device (during its operation) is located above the surface of the cover 8 of the drain tank 9 ( Fig. 1) toilet bowl.

The device works as follows. At the initial moment of time, the device is in standby mode ("standby mode") and the drain hole 13 is closed. The remote control of the proposed device begins to be carried out when the palm of a person's hand or any reflective object is brought to a distance within, for example, 10 cm to the remote infrared sensor 2 (Fig. 4) of the presence, made on the processor board of the control unit 1 (Fig. 1, 4) . The control unit 1 supplies voltage to the electromechanical drive (motor with gearbox) 12 (Fig. 3, 4) of such polarity that the shaft (not shown in the figure) of the drum 15 of the electromechanical drive 12 rotates in the direction of winding the polyamide thread 14 (Fig. 1, 2 , four). Winding on the drum 15 (Fig.3,4), polyamide thread 14 (Fig.1,2,4) raises the rod 16 (Fig.3,4) up, which through the appropriate structural elements of the drain mechanism lifts the sealing ring 18 (Fig. 1, 3, 4) up, thereby opening the drain hole 13 (Fig. 1), which ensures that water is drained from the drain tank 9 (Fig. 1) into the toilet bowl (not shown in the figure). The sealing ring 18 (Fig. 1, 3, 4) is made, for example, of rubber.

When a hand or any reflective object is raised above the remote infrared sensor 2 (Fig. 4) for up to one second, the “small drain” mode of the cistern is activated, lasting for one second. In this case, the light indication 3 displays the "small drain" mode (successively turning on the LEDs clockwise) in blue on the light filter 4 (Fig. 1, 2, 4). After one second (from the moment of activation), if a human hand or any reflective object continues to be in the zone of the remote infrared sensor 2 (Fig. 4), the light indication 3 will change the blue color to blue and the device will switch to the “big drain” mode, in which the sealing ring 18 (Fig. 1, 3, 4) continues to hold the open state of the drain hole 13 (Fig. 1) until the drain tank 9 is completely empty. programmed into the processor board. As soon as the palm of the hand is removed from the remote infrared sensor 2 (Fig. 4), the control unit 1 (Fig. 1, 4) will apply to the electromechanical drive (motor with gearbox) 12 (Fig. 3, 4) a voltage of such polarity at which the drum shaft 15 with polyamide thread 14 (Fig. 1, 2, 4) will begin to unwind, simultaneously lowering the rod 16 (Fig. 3, 4), which, moving, lowers the sealing ring 18 (Fig. 1, 3, 4), the thereby closing the drain hole 13 (Fig. 1). If, after ten seconds from the moment of activation, the reflective object is not removed from the sensitive area, then the drain hole 13 will be forcibly closed, and the device will switch to the “emergency” mode, while the light indication 3 (Fig. 4) of the device will glow red and green flashes.

To switch to the "standby mode" it is necessary to remove the reflective object from the sensitive zone of the remote infrared presence sensor 2.

The water level in the drain tank is regulated by a float (not shown in the figure) of the device, while the maximum allowable water level in the drain tank 9 (Fig. 1) should not exceed the level of the upper end of the pipe 19 (Fig. 1, 3, 4) overflow.

In the absence of power supply, the proposed device can operate in manual (mechanical, contact) mode. In this case, to drain the water, press the light filter 4 (Fig. 1, 2, 4) of the device until it stops and release it, while the light filter 4 through the pusher 5 (Fig. 1.4) acts on the rod 16 (Fig. 3, 4 ), lifting it, thereby rising the ring 18 (Fig. 1, 3, 4) sealing, opening the drain hole 13 (Fig. 1) and water begins to flow from the drain tank 9 into the toilet bowl. The spring 6 (Fig. 1, 4) returns the pusher 5, when the light filter 4 (Fig. 1, 2, 4) is pressed with a finger. In this case, the light filter 4 acts as a push button.

Sleeve 10 (Fig. 3, 4) is designed to center the seat of a single module 7 (Fig. 1, 3, 4) and holes (not shown in the figure) in the lid of the tank 9 (Fig. 1). A single module 7 (Fig. 1, 3, 4) is installed with an interference fit in the hole of the sleeve 10 (Fig. 3, 4). The sleeve 10 is located in the upper part of the drain mechanism 20 (Fig. 1, 3) of the tank 9 (Fig. 1).

The proposed device is powered by a constant voltage of 3.5...5.5 V, ensuring the electrical safety of the consumer during the operation of the device. The power supply unit (not shown in the figure), which is included in the product kit, is connected to the nearest voltage source of 220 V, and in the absence of an electrical outlet in the room, to a lighting lamp.

The proposed technical solution is adapted to the design of the mechanical device (fittings) of the cistern 9 (Fig. 1), shown in the drawing, which controls the supply of water to the toilet.

All components (constituent elements) necessary for the manufacture of the device are standard and are produced by modern industry, which does not cause difficulties in the selection of the elemental and technical equipment of the equipment object. The proposed device is electrically safe for the user during operation.

Unlike the prototype, which uses a bulky device that is installed on the lid of the toilet flush tank and contains separate elements - a control unit, a remote presence sensor, an electromechanical drive, a rod raising element, a mechanical handle, the proposed technical solution is a compact device, the elements of which are built into a single a module with a pusher, and an electromechanical drive with a switching board is made fixed to the fittings of the cistern mechanism, i.e. made built into the body of the toilet cistern, which increases the operational and technical characteristics due to the achievement of compactness, the absence of protruding parts, helping to reduce the likelihood of damage to the device by users, including multiple users, during operation.

Unlike the prototype, in the proposed technical solution, the mechanical drain control knob is replaced by a light filter button with an elastic element, which improves performance due to compactness, tightness, ease of control of the drain device (activation of the water drain mechanism is carried out without touching the surface of the button), creating convenience for the consumer when using the device.

The proposed technical solution uses a multi-color light indication (LEDs are made on the processor board), which visualizes the processes of opening and closing the drain valve (sealing ring), the operating modes of the drain device and its emergency conditions, which improves operational and technical characteristics by informing the user about the operating modes drain tank.

Unlike the prototype, where the device uses a rod control element in the form of a metal tape, the proposed technical solution uses a polyamide thread as a rod control element, which improves performance due to increased flexibility and durability of the thread, as well as its compactness when located on electromechanical drive drum.

The use in the proposed improved device of the tank drain modes and the light indications reflecting these modes on the light filter button helps to reduce the consumption of water and human resources consumed in the conditions of operation of public and private toilets while ensuring the sanitary and hygienic safety of a modern person/consumer.

The proposed technical solution is made with the ability to support external control through remote IR commands, so that the control of the drain valve can be controlled remotely from the control panel, smart home system or other automatic control devices.

All components of the claimed technical solution are interconnected by assembly operations, i.e. are in functional and constructive unity.

Implementation of the proposed utility model allows solving the claimed technical problem and ensuring the achievement of the claimed technical result.

The proposed technical solution, having a constructive unity, implements a common functional purpose (functional unity).

In the prior art, no analogue has been found, characterized by features identical to all essential features of the claimed utility model.
