Abstract

Device for support and automatic cleaning of a small brush, in particular for a W.C., characterised in that it comprises at least one container (10, 12) intended to receive the said small brush, equipped with a pressurised water supply (14) and an outlet (16) in such a way as to ensure the cleaning of this small brush by circulation of water.

Description

The present invention relates to a device for automatically supporting and cleaning a brush including a toilet brush.

In all private places, but more particularly in public places, it is provided for in
A toilet bowl cleaning brush
This toilet brush is a means of cleaning, but it is not itself cleaned. Indeed, it is positioned in a stand on stand, this stand possibly comprising a bowl in which the active part of the brush is dipped.

This bowl can also be filled with a disinfectant liquid which partially ensures the aseptics of the brush.

In the public places and more particularly in the hospitals, the very strict rules of hygiene oblige the personnel to a very rigorous maintenance of all the places being able to be common to the various patients what is the case of WC.

 This type of establishment therefore wishes to have an automatic device for cleaning toilet brushes in order to avoid any problem of contamination or development of bacterial fauna.

The present invention relates to an automatic brush cleaning device which does not require any voluntary intervention by the user, which provides systematic cleaning of the brush, which allows it to be drained after each use in order to prevent the user from spreading water. contaminated water around the device which prevents maintenance of this tool by maintenance personnel, which limits bacterial proliferation, which requires only a diversion on the existing fluid circuits, which can be installed on the installations past and future.

For this purpose the device for automatic cleaning and cleaning of the brush, in particular for W.-C.

according to the invention is characterized in that it comprises a tank intended to receive the said brush, provided with a pressurized water supply and an evacuation so as to ensure the cleaning of this brush by circulation of water.

According to a particular characteristic3 the device comprises a first tank provided with a water supply at the bottom and a second inner tank concentric with the first intended to receive said brush and provided with the discharge.

According to a particular embodiment, the second tank is provided with small diameter bores over its entire periphery3 so as to ensure the passage of the water contained in the first tank to the second tank through said bores.

According to another characteristic, the device comprises a cover integral with the brush and dimensioned to cooperate with the first tank.

The device is removed from the bottom of the second tank and also includes a siphon.

The device is mounted in parallel on the water supply and drainage circuit of the toilet. In this case, provision is made for interposing a flow control valve on the bypass circuit.

The present invention is described below according to a particular embodiment with reference to the accompanying drawings in which - Figure 1 shows a support and cleaning device according to the invention, seen in section, and - Figure 2 shows a view schematic of an installation provided with this support and cleaning device.

FIG. 1 shows the support and cleaning device according to the invention which comprises a first external tank 10, a second concentric internal tank 12 as well as a water supply 14 and a discharge 16.

The standard type brush 3 comprises a handle 18, provided at its lower end with a large number of synthetic fibers 20 constituting the active part of this accessory.

On the handle 18 there is provided a cover 223 integral with this handle and the diameter of which is dimensioned to ensure the closure of the first tank 10.

The cover 22 also comprises bores 23 intended to vent the interior volume of the first tank 10.

This first tank 10 includes a peripheral wall 24 and a bottom 26.

The water supply 14 opens into the first tank 10 immediately above the bottom 26, through the wall 24. The bottom 26 further comprises a bore 28, the use of which will be indicated later "
The second tank 12 is mounted concentric with the first and its diameter is less than that of the first so as to provide a free space 30 for peripheral circulation between the first and the second tank.

This second tank is provided over its entire wall with bores 32 of small diameter and oriented perpendicular to the wall. The tank 12 is extended at its lower part by a discharge pipe 34 which passes through the bore 28 formed in the bottom 26 of the first tank. The seal is ensured by a seal 36, blocked by a nut 38 screwing into the threaded bore 28. At the end of this evacuation pipe 34, an anti-odor siphon 40 is provided.

This second tank 12 is intended to receive the active part of the Sweeper, the cover centered with respect to the first bowl ensuring the maintenance in position of this sweeper. The second tank is lower than the first tank.

In Figure 2 there is shown an installation diagram of the support and cleaning device according to the invention.

The installation comprises, in known manner, a general water supply 42 provided with a shut-off valve 44 ensuring the filling of the flushing tank 46, itself fitted at its outlet with an isolation valve 48.

This tank 46 feeds a toilet bowl 503 itself provided with an evacuation pipe 52.

On the pipe which connects the tank 46 to the toilet bowl 50 there is provided a bypass 14 for supplying water to the first tank 10 of the device according to the invention.

Furthermore, the second tank 12 is connected by its evacuation duct 34 and through the siphon 40 to the main evacuation pipe 52.

The operation of the invention is described below.

As soon as the flush 46 is actuated, the water contained in the tank flows through the isolation valve 48 in the direction of the bowl.
WC 50 on the one hand and in the direction of the support and cleaning device according to the invention on the other hand the proportion derived being determined by the adjustment of a flow control valve 49.

The water enters the first tank through the supply line 14, and under the effect of the pressure this water passes through the bores 32 under the pressure generated by the flush, thus creating a multitude of jets under pressure. The level rises to above the second tank 12, the height of which is less than that of the first tank and the water passes over the second tank in the manner of an overflow.

Furthermore, 1 water from the second tank is evacuated through the evacuation pipe 34 and the siphon 40 towards the main evacuation pipe 52.

The flow valve 49 of the supply line 14 of the device according to the invention makes it possible to avoid any overflow which could result from too great a flow.

Furthermore, the cover 22 remains in position since the pressurized air contained in the first tank 10 during its filling is evacuated through the bores 23 of the cover 22.

Simultaneous with the introduction of water into the device according to the invention, there is provision for its evacuation, so that the second tank empties completely3 thus causing a suction which completes the cleaning of the jets from the small diameter bores 32 .

Such a device allows automatic cleaning of the brush at each use.

Another embodiment provides an intermediate buffer tank with emptying triggered when the brush is replaced so that it is systematically cleaned after use.
