Description

Technical area

The present invention relates to a cleaning device for cleaning toilets (also toilet cleaning device) according to claim 1, which is generally rod-shaped.

Background and state of the art

Conventional toilet brushes usually have an inflexible plastic handle with a brush head. Even the models with a side-mounted edge cleaner do not reach all places in the toilet. This means that neither the toilet bowl nor the rim are hygienically cleaned. Even with thorough cleaning, it is proven that germs, bacteria and the well-known and dangerous coliform bacteria remain, which can lead to infectious diseases. Cleaning with the conventional toilet brush is carried out with the upper body bent forward, with the cleaning person's face bent so close to the toilet bowl that the spray water reaches the face and skin as droplets during cleaning. When using this brush, it is not uncommon to find scraps of paper from the predecessor in the brush head, this is the least of it. Often you lift the brush out of a container in which water with a lot of germs has accumulated. Before the brush reaches the toilet bowl for cleaning, a few drops usually fall onto the edge of the glasses and represent a source of bacteria. This is not appropriate for the 21st century.

When cleaning with the classic toilet brush, large amounts of cleaning agents are usually used to try to reach every spot under the toilet rim and in the toilet knee above and especially under the water. Because these are the places where increased deposits of urine scale, bacteria and germs occur.

According to the Federal Institute for Population Research, there are around 41 million households with two people in Germany alone. Large families, single households, schools, hospitals and other public institutions, including restaurants, are not included here. Based on these 41 million households that dispose of the brush set every 6 months, plastic waste - calculated at an average of 200 grams - amounts to 8,200 tonnes. This rough calculation does not even include the packaging material and the production of CO2 and fine dust during delivery.

In motorway toilets, in hospitals and many other public facilities, it is now common practice for the toilet seat to be completely removed and disinfected after each use of the toilet. There are contactless fittings, soap dispensers and electronic hand dryers. The lights are also switched on automatically with the help of motion detectors, but the toilet brush is still placed in a corner that no one really wants to come into contact with.

Task and summary of the invention

The object of the present invention is therefore to at least partially solve the above disadvantages of the prior art and to provide a cleaning device for toilets which effectively cleans a toilet when using a fragrance and/or cleaning agent. The aim is to ensure a constant and unhindered flow of water mixed with fragrance and/or cleaning agents.

This task is solved by a cleaning device with the features of claim 1.

Advantageous embodiments are described in the dependent claims.

In particular, the object is achieved by a cleaning device for cleaning toilets, the cleaning device consisting at least partially, preferably completely, of an antibacterial plastic.

The invention will now be described with reference to 1 to 5 , which show an advantageous embodiment, explained.

The cleaning device 1 for cleaning toilets is in a connected state 5 shown, in which it is arranged in a holding device 8 next to a toilet. The cleaning device 1 has a hose 13, which can be connected to a water connection in order to provide water for the cleaning device 1 via the hose 13 (cf. 5 ).

In 5 the cleaning device 1 is connected to a cistern 9 of a toilet via a suitable water connection 7 and the hose 13, wherein the water connection can advantageously be designed as a water inlet valve. According to the invention, the connection of the cleaning device 1 is also via the hose 13 and A suitable adapter can be connected to any other water supply source in the household.

The cleaning device 1 advantageously consists at least partially, preferably completely, of an antibacterial plastic. The cleaning device preferably has a rotationally symmetrical shape. However, according to the invention, elliptical or other flattened shapes are conceivable, especially for ergonomic handling of the device.

The cleaning device 1 is now based on 1 described in more detail. The cleaning device 1 has a handle 2 which is attached to the hose 13 mentioned above. Both permanent or releasable attachment are conceivable according to the invention, as long as the tightness of the connection is guaranteed. The handle 2 also includes a water regulator 5 in order to use the water regulator 5 to adjust the inflow of water into the cleaning device 1. According to the invention, both an on/off control and a control in which the water flow rate can be adjusted are conceivable. Advantageously, the water flow rate is regulated via two push buttons, as shown. The handle 2 can, as shown in the figures, be designed rotationally symmetrically as a circular cylinder. A flattened design of the handle 2 for ergonomic handling is also conceivable according to the invention.

In addition, the cleaning device 1 has a tube 3, which is connected to the handle 2. The connection is preferably designed as a tight screw connection or quick-release fastener.

Advantageously, the tube 3 also has a filter system which is arranged in the tube 3. The filter system divides the pipe 3 into an upstream region with a substantially constant cross section and a downstream tapering region 17 which accelerates the flow. The filter system can, for example, comprise a sieve 10, which is preferably arranged in a sieve bed 11 for stabilization. The sieve bed 11 also advantageously allows the sieve 10 to be replaced if necessary. The upstream area of the tube 3 forms a mixing space 6 for receiving a fragrance or cleaning agent and the downstream area 17 of the tube 3 is designed to accelerate the fragrance or cleaning agent mixed with water. The filter system is advantageous in that particles resulting from the dissolution of the fragrance or cleaning agent are collected and thus do not clog the downstream area of the pipe 3, in particular a nozzle described below and/or a check valve described below.

The downstream region also has a nozzle 12 at its outlet. The nozzle 12 is designed, for example, as a flat jet nozzle.

The downstream region has a constriction 14 upstream of the nozzle 12, the constriction 14 being designed to accommodate a check valve. The check valve can be designed as a ball check valve, as in the 1 , 2A , 2 B and 4 visible. wherein the ball check valve has a ball 15 closing the constriction 14 and a spring 16, the spring 16 acting on the ball 15 against the constriction 14. Ball 15 and/or spring 16 can advantageously be made of silicone.

The combination of ball 15 and constriction 14 thus increases the hydrostatic pressure in particular. The ball 15 completely closes the constriction 14 in the depressurized state, so that the water is prevented from flowing out. In the 2A This unpressurized state is shown, while in 2 B Water pressure is present, so that water is conveyed past the ball 15 and out of the nozzle 12.

In 4 a sectional view of the tube 3 can be seen. It can be seen in particular that the mixing space 6 is present at the end which faces the handle 2. Fragrances or cleaning agents can be introduced into the mixing chamber 6 as required in order to mix the water flowing through. Downstream of the mixing chamber 6 is in the embodiment according to 4 the sieve 10 is arranged, which is present in a sieve bed 11 for stabilization.

Within the scope of the invention, it is conceivable that the cleaning device 1 has lighting means in order to at least partially illuminate the cleaning device 1, which, however, is not shown in the figures.

The handle 2 of the cleaning device 1 according to the invention can also have vibration means. For example, ongoing operation of the device and/or the absence of fragrance or cleaning agent can be signaled. The vibration generated by the vibrating agent can also better mix a solid fragrance or cleaning agent with the water flowing through it.

It is also conceivable that in an embodiment not shown in the figures, the cleaning device 1 also has a display and at least one sensor in order to display a Flow rate, a flow pressure and / or a fill level of the fragrance or cleaning agent in the mixing room 6 to provide. In addition, the cleaning device 1 can in particular further have a water wheel with a dynamo in order to supply the display and the sensor with power, the electricity being generated by a flow of water through the cleaning device 1.

It can be advantageous if the tube 3 is designed to be flexible, in particular as a corrugated tube.

In a further possible embodiment, not shown, the handle 2 and the tube 3 each have a connecting element in order to arrange an extension element between the handle 2 and the tube 3 via the respective connecting elements. It is also conceivable to provide a single connecting element. The pipe 3 may also preferably have an extension element between the downstream end of the pipe 3 and the nozzle 12, so that the nozzle 12 can extend into further areas of the toilet.

The connecting element(s) within the scope of the present invention can be designed as snap or latching elements or alternatively as complementary threads.

In addition, the hose 13 can have a backflow preventer and/or an aquastop at the end that can be connected to the water connection.

The cleaning device according to the invention advantageously works with the help of the high water pressure, which makes the use of urine scale remover completely unnecessary. If necessary, a fragrance and/or cleaning agent can be filled into the mixing chamber 6, which is located inside the cleaning device 1. The invention is a significantly more hygienic toilet bowl cleaning device than the tried and tested toilet brush. The toilet cleaning device developed is operated by water pressure and enables thorough and hygienic cleaning without bristles and contamination.

In addition, the cleaning device 1 according to the invention is free of a collecting container, as is known from toilet cleaning brushes. This means that germs and bacteria no longer accumulate in unhygienic toilet brush containers. In addition, the cleaning device is made of antibacterial plastic, so that germs and bacteria can also be prevented from sticking.

Furthermore, the toilet cleaning device counteracts high levels of waste.

It is also important to mention that, unlike a conventional toilet brush, the purchase costs are only one-off.

The cleaning device 1 is preferably connected to an existing water inlet valve of a cistern 9, in particular using a branch distributor (T-piece), and can be attached to a wall or the cistern 9 using a holding device 8. Inside the cleaning device 1 there is the mixing room 6 to mix the water with cleaning agents and/or fragrances. This innovative system enables germ-free cleaning with the cleaning device 1 and has the advantage that, unlike the classic toilet brush, no germs and bacteria stick to the toilet cleaning device 1 and therefore neither spread nor multiply.

• Das Wasser wird über den Schlauch 13 und anschließend durch den Griff 2 in den Mischraum 6 des Rohres 3 gefördert und wird dort mit den Duft- und/oder Reinigungsmitteln gemischt. Anschließend wird das Gemisch durch den Sieb 10 eines Filtersystems gefördert und somit von Überresten befreit, um die Düse 12 nicht zu verstopfen. Das Sieb 10 wird für eine zusätzliche Stabilität unterstützt durch ein Sieb-Bett 11. Nun strömt das Fluid bzw. Wasser in die Verengung 14 des Rohres 3, dort nimmt die Strömungsgeschwindigkeit aufgrund der Rohrverengung 14 ab, was dazu führt, dass der hydrostatische Druck zunimmt. In diesem Prozessschritt befindet sich eine weitere Technologie, die das unkontrollierte Nachtropfen im Ruhezustand unterbindet. An der Spitze des Rohrs 3 befindet sich bevorzugt die Kugel 15, beispielsweise eine Silikonkugel, mit Widerstand durch die Druckfeder 16, die das Rohr 3 im Bereich der Verengung 14 im Ruhezustand verschließt, sodass ein Nachtropfen unterbunden ist. Betätigt man aber nun den Wasserregler 5 wird nimmt der hydrostatische Druck zu und somit wird die Kugel 15, insbesondere Silikonkugel, in Richtung der Feder 16 gedrückt, wodurch das Wasser durch die Düse 12 austritt.

The functional principle according to the invention is preferably as follows:

• The water is conveyed via the hose 13 and then through the handle 2 into the mixing space 6 of the pipe 3 and is mixed there with the fragrances and/or cleaning agents. The mixture is then conveyed through the sieve 10 of a filter system and is thus freed from residues so as not to clog the nozzle 12. The sieve 10 is supported by a sieve bed 11 for additional stability. Now the fluid or water flows into the constriction 14 of the pipe 3, where the flow velocity decreases due to the pipe constriction 14, which leads to the hydrostatic pressure increasing . This process step contains another technology that prevents uncontrolled dripping when at rest. At the tip of the tube 3 there is preferably the ball 15, for example a silicone ball, with resistance from the compression spring 16, which closes the tube 3 in the area of the constriction 14 in the resting state, so that dripping is prevented. But if you now operate the water regulator 5, the hydrostatic pressure increases and the ball 15, in particular the silicone ball, is pressed in the direction of the spring 16, whereby the water emerges through the nozzle 12.

Although the invention has been described in connection with water, it may also be used in connection with other similar liquid or fluid. The invention can also be used with water at a pressure present in conventional pipes as well as with excess pressure. In any case, the design of the cleaning device 1 according to the invention increases the speed and/or pressure of the emerging water jet.

The toilet cleaning device 1 was developed with the highest precision in order to achieve maximum hygiene. In an advantageous embodiment, the length of the device is approximately 50cm (tube 3 approximately 40cm; handle 2 approximately 10cm) in order to be able to ensure a hygienic distance during use.

The embodiments shown here represent only examples of the present invention and should therefore not be construed as limiting. Alternative embodiments contemplated by those skilled in the art are equally included within the scope of the present invention.
