Description

Device for dispensing in the discharge of water and / or to mix with the water discharge detergent products and / or disinfectants and / or deodorants, in toilets or devices hydraulic and sanitary in general.

The present invention refers to a device for dispensing in the discharge of water and / or for mixing with the discharge of water detergent products and / or disinfectants and / or deodorants, in toilets or hydraulic and sanitary devices in general.

Toilet dispensing devices Detergent products and / or disinfectants and / or deodorants in condition solid, packaged in the form of water soluble tablets or bars, They are known. These devices are generally constituted by a support structure that is composed of an enclosure with a cage-shaped structure that internally forms a tablet or bar receptacle and a suspension arm in hook shape that is connected to the enclosure and that can hook the edge of the toilet to support the enclosure below the edge of the toilet, where the holes to dispense the discharge of water from the Toilet are provided. In this way, every time the system Toilet discharge is operated, water discharge hits the enclosure, gradually dissolving the tablet or bar and therefore mixing detergent and / or disinfectant products and / or Deodorants with water discharge.

When using these devices, very often you find uneven wear of the tablet or bar, put that the discharge of water hits different regions differently of the tablet or bar. This uneven wear very often causes an unwanted breakage of the tablet or bar, releasing pieces not dissolved in the water discharge, and therefore with a consumption little effective of the tablet or bar in terms of cleaning the toilet.

In addition, with these devices the substances that make up the tablet or bar dissolve in the water discharge in an unsatisfactory way and foam generation is limited and normally enhanced by resorting to an increase in the content of surfactants in the substances that make up the tablet or bar.

Toilet dispensing devices detergent products and / or disinfectants and / or deodorants, in the Liquid state or as a gel, are also known. These devices are provided with at least one tank, which is hung from the edge of the toilet and contains detergent products and / or disinfectants and / or deodorants, and the products are dispensed in water discharge normally using the cleaning action of the water in a preset region of the device, in which a a certain amount of such products is dispensed, usually by gravity.

Even with these devices, very often detergent products and / or disinfectants and / or deodorants are mix in the water discharge in a way that is not completely satisfactory, and there is limited foam generation depending the shape of the toilet, the strength of the water jet and the water discharge direction in the device.

In toilets served by a cistern for store the water discharge, the water discharge can receive the addition of detergent and / or disinfectant products and / or deodorants, which are placed inside said cistern.

In this case too, very often the mixture of detergent and / or disinfectant and / or deodorant products in the water discharge is not completely satisfactory and the generation Foam is limited.

WO 2004/005631 shows a device for clean and disinfect a toilet using a liquid composition that comprises an oscillating tray under a composition tank liquid

GB-A-2 349 157 shows an apparatus for dosing an active agent in the discharge of water from a toilet in which the active agent is inside a partially rotating tank.

DE-A-199 20 897 shows a device to clean a toilet in which a tank It is arranged to release a dose of disinfectant product liquid between the blades of a rotating element.

The objective of the present invention is to provide a device for dispensing in the discharge of water and / or for mix detergent products and / or water discharge disinfectants and / or deodorants, in toilets or devices hydraulic and sanitary in general, to ensure the optimal mix of detergent and / or disinfectant and / or deodorant products in the water discharge

Within this objective an object of the invention is to provide a device that, for the same products detergents and / or disinfectants and / or deodorants used, get greater foam generation and longer retention of the foam generated with respect to the types of known devices.
