Description

AUTOMATIC TOILET CLEANER

FIELD The disclosure relates to toilet cleaning. More particularly, the disclosure herein relates to systems and methods for automatic toilet cleaning.

BACKGROUND The procedure of cleaning a toilet is usually time consuming and also cumbersome.

This is a result of the unique structure of the toilet bowl, which requires meticulous movements and gestures by the person cleaning the toilet in order to thoroughly clean all parts of the toilet bowl. Typically, such cleaning is carried out using a toilet brush, whereby the person cleaning the toilet cleans a single toilet in up to ten minutes.

There are several commercially available solutions for enhanced toilet cleaning. These solutions typically involve some sort of detergent (usually in the form of a capsule) that is embedded into the toilet bowl, for example attached to the inner side of the bowl, and release a small amount of detergent with every flush of the toilet. Additionally, some solutions are embedded into the toilet tank and are directly connected to the water supply such that every flush releases a small amount of detergent from the toilet tank.

However, such commercially available solutions cannot provide a comprehensive solution since some stains in the toilet bowl require physical contact in order to be removed (e.g. contact with a toilet brush), since some stains have a dry surface connection to the inner side of the toilet bowl while detergent material flushed into the bowl only contacts the outer surface of these stains. Therefore, manually cleaning with a toilet brush is still required.

It is therefore an object to provide a portable device for automated toilet cleaning, to replace a manually operated toilet brush. Further objects and advantages will appear as the description proceeds. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the embodiments belong. Although methods and materials similar or equivalent to those described herein can be used in the practice or testing, suitable methods and materials are described below.

Before explaining at least one embodiment in detail, it is to be understood that the embodiments is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. Other embodiments can be practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting. In discussion of the various figures described herein below, like numbers refer to like parts. The drawings are generally not to scale.

For clarity, non-essential elements were omitted from some of the drawings.

Fig. 1 schematically illustrates a commercially available toilet 10. The commercially available toilet 10 has a toilet bowl 12 with a rim 11 and an inner surface 13 to be cleaned by the user, typically with a toilet brush. The commercially available toilet 10 further has a toilet tank 14 accommodating water to be dispensed into the toilet bowl 12 with every flush, and also a toilet seat 15 capable of covering the toilet bowl 12. Since manually cleaning the toilet bowl is time consuming, it would therefore be advantageous to have an automatic solution that may simulate the physical toilet cleaning operation of a toilet brush without the need of manual intervention. Referring now to Fig. 2, this figure schematically illustrates a perspective view of an automatic cleaning system 20 assembled onto an existing commercially available toilet 10. The automatic cleaning system 20 may couple to the rim 11 of the toilet bowl 12, using at least one arm 21, while the other elements of the automatic cleaning system 20 remain on the inner side of the toilet bowl 12. Optionally, the at least one arm 21 may be partially elastic so as to couple to any shape of toilet bowl.

The toilet seat 15 may then be placed onto the automatic cleaning system 20 so as to allow normal use of the toilet 10 while the automatic cleaning system 20 may operate independently. It should be noted that the only element of the automatic cleaning system 20 positioned between the toilet bowl 12 and the seat 15, is the at least one arm 21. Preferably, the at least one arm 21 is sufficiently thin so as to allow positioning the seat 15 onto the automatic cleaning system 20 such that a user sitting on the seat does not feel a difference after the addition of the automatic cleaning system 20. It is appreciated that the automatic cleaning system 20 may be assembled onto any type of toilet, whereby the automatic cleaning system 20 is easily coupled to the rim of the toilet bowl with the at least one arm 21. Thus, the automatic cleaning system 20 may automatically clean the inner surface 13 of the toilet bowl 12 (further described hereinafter), while the seat 15 may be placed onto the automatic cleaning system 20 such that normal use of the toilet may be allowed.

The initiation of the cleaning operation may be commenced by built-in sensors in the automatic cleaning system 20, and triggered with every flushing of the toilet. For example, an acoustic sensor that triggers the cleaning operation upon recognition of the flushing sound, and/or a motion sensor that that triggers the cleaning operation upon recognition of flowing water inside the toilet. Additionally or alternatively, the cleaning operation may be commenced with a predetermined time period (for instance, once every hour). In some exemplary embodiments, the automatic cleaning system 20 may be mutually coupled with an automatic and/or a touch-less toilet flusher, capable of flushing the toilet upon detecting motion/presence. It should be noted that, the coupling comprise wirelessly obtaining a signal, indicating that flushing has began, from the automatic/touch-less flush, thus initiation the cleaning operation. In some exemplary embodiments, the built-in sensors commencing the cleaning operation may comprise motion sensor, proximity sensor, presence sensor, a combination thereof, or the like, such as the automatic and/or a touch-less toilet flusher.

Referring now to Figs. 3A-3C, these figures illustrate the elements of the automatic cleaning system. Fig. 3 A schematically illustrates a perspective view of the automatic cleaning system 20 assembled onto a rim 11 of the toilet bowl, and Fig. 3B schematically illustrates a perspective view of the automatic cleaning system 20 without the rim 11.

It should be noted that while the automatic cleaning system 20 may be assembled onto a rim 11 of the toilet bowl with at least one arm 21, the at least one arm 21 may further comprise a clinging segment 31 configured to allow clinging the at least one arm 21 onto the outer edge of the toilet bowl.

The automatic cleaning system 20 comprises an annular rail 22 configured to be adjacent to the rim 11, and an articulated cleaning system 30 that is coupled to and moving on the rail 22, further described hereinafter. Preferably, the articulated cleaning system 30 comprises three coupled segments that move together along the rail 22. Namely, a control segment 32, a driver segment 34, and also a cleaning segment 36. Fig. 3C schematically illustrates a perspective view of the elements of the articulated cleaning system 30. The control segment 32 is coupled to the driver segment 34 with a first flexible joint 33, and the driver segment 34 is coupled to the cleaning segment 36 with a second flexible joint 35. It should be noted that among these elements only the driver segment 34 is coupled to the rail with at least one wheel 38, further described hereinafter. During the movement of the articulated cleaning system 30 along the rail, the driver segment 34 moves along the rail while the coupled control segment 32 and the cleaning segment 36 move along with the driver segment 34. In some embodiments, the first and second flexible joints 33, 35 are hollow elastic joints that protect electric cables passing through them, for instance protect from damages of water flow in the toilet. Specifically, the first flexible joint 33 protects a first electric cable passing from the control segment 32 to the driver segment 34 such that the control segment 32 may control the motion of the driver segment 34. Similarly, the second flexible joint 35 protects a second electric cable passing from the driver segment 34 to the cleaning segment 36, such that the control segment 32 may in turn control the operation of the cleaning segment 36.

Referring now to Figs. 4A-4B, these figures illustrate the elements of the control segment 32. Fig. 4A schematically illustrates a perspective view of the control segment 32, and Fig. 4B schematically illustrates a cross-sectional view of the same. The control segment 32 comprises a first connection element 41 configured to allow connection to the first flexible joint 33 and/or the driver segment 34 (for instance as shown in Fig. 3C). Additionally, the control segment 32 further comprises a power compartment with at least one power storage element 43 (typically a standard battery), and also a control board 42 (e.g. a PCB) configured to control the movement of the entire articulated cleaning system 30 along the rail, and particularly control the motion of the driver segment and the operation of the cleaning segment via electric cables passing from the control segment 32 and to the driver and cleaning segments.

Referring now to Figs. 5A-5C, these figures illustrate the operation of the driver segment. Fig. 5A schematically illustrates a perspective view of the driver segment 34, and Fig. 5B schematically illustrates a partial cross-sectional view of the driver segment 34 attached to the annular rail 22 of the automatic cleaning system 20.

Similarly to the control segment, the driver segment 34 has at least one second connection element 51 configured to allow connection to the first flexible joint 33 and/or the control segment 32 (for instance as shown in Fig. 3C). Optionally, the driver segment 34 has additional second connection element 51 configured to allow connection to the second flexible joint 35 and/or the cleaning segment 36.

The at least one wheel 38 of the driver segment 34 is configured to fit into a track of the rail 22. The driver segment 34 may comprise a built-in motor (further described hereinafter) that rotates the at least one wheel 38. Rotation of the at least one wheel 38 onto the rail 22 may therefore move the driver segment 34 along the rail 22, and consequently the control 32 and cleaning 36 segments that are coupled to the driver segment 34. It should be noted that the operation of the motor of the driver segment 34, and thereby the movement of the automatic cleaning system 20 along the rail 22, may be controlled by the control segment 32.

Fig. 5C schematically illustrates a partial cross-sectional view of the driver segment 34. The driver segment 34 may comprise a built-in motor 54 (e.g. a step motor), that is coupled to the at least one wheel 38 and capable of rotating the at least one wheel 38.

In some embodiments, the driver segment 34 may also comprise a first elastic element 55 (e.g. a spring) that is coupled to an additional wheel 38 in order to allow corresponding rotation of the two wheels 38 onto the rail 22 such that a desired motion of the driver segment 34 may be achieved. Preferably, the position of the additional wheel 38 relatively to the driver segment 34 is not fixed such that both wheels may move along the rail 22 with a changing distance between them, for example may be required as some portions of the angular rail 22 may be curved and in order to move there the wheels 38 must slightly change the distance between them. The first elastic element 55 may keep a minimal distance between the wheels 38 such that both wheels about the rail 22.

It is appreciated that the driver segment 34 thus provides the desired horizontal movement along the annular rail 22, wherein the control segment controls the motion. Referring now to Figs. 6A-7, these figures illustrate the elements of the cleaning segment. Fig. 6A schematically illustrates a perspective view of the cleaning segment 36, and Fig. 6B schematically illustrates a partial cross-sectional view of the same. Similarly to the control segment, the cleaning segment 36 has at least one third connection element 61 configured to allow connection to the second flexible joint 35 and/or the driver segment 34 (for instance as shown in Fig. 3C). Optionally, the cleaning segment 36 may also have at least one cover connector 63 configured to allow connection of the cleaning segment 36 to the cleaning cover (for instance as shown in Fig. 7).

Preferably, the cleaning segment 36 is coupled to a brush 64 having a rounded balllike head, configured to simulate the brushing operation while manually cleaning a toilet bowl. The cleaning segment 36 may be coupled to the brush 64 with shaft 62 configured change the length and thus change the vertical position of the brush 64, further described hereinafter. Optionally, the operation of the shaft 62 is controlled by the control segment.

The cleaning segment 36 may optionally comprise a spring 65 configured to maintain a predefined distance between the cleaning segment 36 and the brush 64. In some exemplary embodiments the spring 65 may assist in raising the brush towards the cleaning segment 36 and therefore allow lower power consumption of the system in order to overcome the gravitational force pulling the brush 64 downwards. Alternatively, spring 65 may be assembled in a way that assists lowering the brush away from the cleaning segment 36.

In some exemplary embodiments, the brush may be coated with hydrophobic and oleophobic material, which repel water, mud, other liquids, sticky materials, a combination thereof, or the like. These hydrophobic and oleophobic coatings cause liquids to form nearly perfect spheres, which roll off the surface of the coated substrate, thus keeping the brush dry and clean. Optionally, the brush may be a separate element and replaced by the user after a certain period of time (e.g. replaced once a year). The operation of the brush 64 may be achieved with two corresponding motors. Namely, a rotation motor 66 and a height motor 68 that may operate separately or alternatively operate simultaneously in order to achieve a desired motion. The rotation motor 66 may be directly coupled to the shaft 62 and rotate the shaft 62 around it's axis in order to rotate the brush 64 such that a brushing procedure may occur. Alternatively, the height motor 68 is directly coupled to the shaft 62 and the rotation motor 66 may be coupled to the shaft 62 with an elastic belt 67. Thus, the height motor 68 may move the shaft 62 so as to change the distance between the cleaning segment 36 and the brush 64, for example by winding the shaft 62 onto a reel, and the rotation motor 66 may in turn move the belt 67 so as to rotate the shaft 62 around it's axis. It should be noted that the cleaning segment 36 thus provides the desired vertical movement for the brushing procedure, wherein the control segment controls the motion by controlling the rotation motor 66 and the height motor 68.

Optionally, the brush 64 may be lowered by the height motor 68 until it contacts the bottom of the toilet bowl such that the entire toilet may be cleaned. It is appreciated that as different countries use different structures of toilet bowls, the automatic toilet cleaner may be adapted for specific toilet structures, for instance with elongated brush movements such that the entire toilet bowl may be cleaned.

Fig. 7 schematically illustrates a cleaning cover 70 that is compatible with the cleaning segment 36. The cover 70 may at least partially cover the cleaning segment 36 such that water flowing after flushing of the toilet does not damage the mechanical elements (e.g. the shaft and motors). Additionally, the cover 70 may protect the cleaning segment 36 from damages caused by physical contact with the toilet bowl. The cover 70 comprises a connector 71 configured to allow connection to the at least one cover connector of the cleaning segment 36. It should be noted that the connection to the cleaning segment 36 is flexible, and the position of the cover 70 relatively to the cleaning segment 36 may change according to the contact of the cover 70 with the toilet bowl.

In some embodiments, the cover 70 further comprises a disinfection cartridge 72, having an aperture 73. The disinfection cartridge 72 may be filled (e.g. by the user) with a capsule (not shown). The capsule may be comprised of material, such as a disinfecting substance, a cleaning detergent, a combination thereof, or the like. A portion of capsule material may be released into the toilet bowl during the brushing procedure (cleaning operation). Preferably, the physical contact between the cover 70 and the toilet bowl may press the disinfection cartridge 72 so as to release a portion of capsule material through the aperture 73 such that the material may reach the brush cleaning the toilet.

It is appreciated that such automated toilet cleaning may be particularly advantageous in public facilities having numerous toilets, for example large sport stadiums having hundreds of toilets. In order to manually clean all of these toilets (wherein daily cleaning is required) it may take several hours and employ several workers. However, using the abovementioned automatic cleaning system, all of the toilets are automatically cleaned such that the requirement to employ an entire cleaning crew to clean every toilet bowl in the facility may be eliminated.

In some exemplary embodiments of the disclosed subject matter, the automatic cleaning process of a structure's inner wall may comprise operations such as; brushing the inner wall with a brush that articulated, by driver segment 34, on the structure's inner wall; spinning the brush about its longitudinal axis; linearly moving the brush along the brush longitudinal axis; homing the brush to an origin position; a combination thereof, or the like. It should be noted that while the above discusses cleaning of toilet, the same methods may be applied for automatic cleaning of other objects that are commonly cleaned with a brush, wherein the structure of the rail may require adaptation for the new object. It should be also noted that, no attempt is made to show structural details in more detail than is necessary for a fundamental understanding of the disclosed subject matter. Furthermore the apparatus structure and its method of operation, described in the preferred embodiment above, may be altered (redesign) due to ongoing effort of cost reduction; performance, reliability, and maintenance improvements; a combination thereof, or the like. As an example, the control module may be relocated to the toilet outer wall. Another example, the apparatus may utilize an external power supply for its operation. As yet another example, the cleaning operation may be initiated manually by a push of a button. It is appreciated that certain features of the embodiments, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the embodiments, which are, for brevity, described in the context of a single embodiment, may also be provided separately or in any suitable sub combination.

Although it been described in conjunction with specific embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, it is intended to embrace all such alternatives, modifications and variations that fall within the spirit and broad scope of the appended claims.
