Description

DEVICE FOR CLEANING A TOILET BOWLCROSS-REFERENCE TO RELATED APPLICATIONThis application claims priority to United States Provisional Patent Application No.63 / 483,286, filed February 05, 2023, the entire contents of which is incorporated herein by reference in its entirety.FIELD

[0001] The present subject matter relates to toilet bowl. More particularly, the present subject matter relates to devices for cleaning toilet bowls.BACKGROUND

[0002] The procedure of cleaning a toilet bowl 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 bowl 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 bowl may be exposed to detergent and dirt that may be sprayed during cleaning. Another disadvantage of using a brush for cleaning a toilet bowl is the accumulation of dirt and microorganism, some of which may be pathogenic, on the brush, particularly between and on the surface of brush bristles.

[0003] There are several commercially available solutions for toilet bowl cleaning that do not require human contact. 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 bowl. 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.

[0004] However, such commercially available solutions cannot provide comprehensive cleaning of the toilet bowl since some stains in the toilet bowl require physical contact in order to be removed, for example, contact with a toilet brush. This is because some stains have a drysurface connection to the inner side of the toilet bowl while a detergent material flushed into the bowl only contacts the outer surface of these stains and does not remove them.SUMMARY

[0054] Before explaining at least one embodiment in detail, it is to be understood that the subject matter 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. The subject matter is capable of other embodiments or of being 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.

[0055] One aim of the present subject matter is to provide a device for automated cleaning of toilet bowls, replacing manual cleaning of the toilet bowls. Another aim is to provide a device that automatically cleans hard stains in the toilet bowl, namely stains that require physical contact in order to be removed. Yet another aim of the present subject matter is to provide a device that can be installed on and adjusted to any type of toilet bowl. Still another aim is to provide a device for cleaning toilet bowls that does not require connection of the device to the mains water supply, but rather uses water that is regularly flushed into the toilet bowl after usage of the toilet bowl. A further aim is to provide a device for cleaning toilet bowls that does not require connection of the device to the mains electricity supply, but rather uses an internal electrical power source. Yet a further aim is to provide a device for cleaning toilet bowls that also illuminates the toilet bowl and its vicinity independently of the cleaning of the toilet bowl. An additional aim is to provide a device for cleaning toilet bowls that can be easily installed on any existing toilet bowl. Yet an additional aim is to provide a device for cleaning toilet bowls that can be easily removed from a toilet bowl. The device for cleaning toilet bowls of the present subject matter addresses all these aims.

[0056] Referring now to Figs. 1A-B schematically illustrating, according to an exemplary embodiment, a front perspective view and a back perspective view, respectively, of a device for cleaning toilet bowls. For the sake of simplicity, the device for cleaning toilet bowls is occasionally termed hereinafter “device 1”. According to one embodiment, the device 1 comprises:a bridge 12 configured to be placed on a rim of a toilet bowl and comprising a first edge 122 and a second edge 124; a container 14 extending down from the first edge 122 of the bridge 12 and configured to be placed in the toilet bowl, under a part of the rim of the toilet bowl where water flushes into the toilet bowl, wherein an interior of the container 14 is configured to be filled with flush water that flows from the rim of the toilet bowl into the toilet bowl; a sprinkler 16 positioned on a side of the container 14 that faces the toilet bowl and configured to sprinkle a jet stream of water into the toilet bowl, wherein the sprinkler 16 comprises at least one sprinkler motor configured to move the sprinkler 16 and direct the jet stream of water to any spot on the toilet bowl; a control unit 18 attached to the second edge 124 of the bridge 12 and configured to reside at an outer side of the toilet bowl rim and control operation of the device 1 ; a pump positioned in the control unit 18 and fluidically connected to the interior of the container 14 and to the sprinkler 16, wherein the pump is configured to pump water from the container 14 and force flow of the water toward the sprinkler 16 in a manner that causes a formation of the jet stream that is sprinkled from the sprinkler 16; at least one electrical power source positioned in the control unit 18 and electrically connected to the pump 20 via a pump switch; and a control electronic circuit positioned in the control unit 18 signally connected to components of the device and configured to control operation of the components of the device.

[0057] An advantage of the present subject matter is that the supply of water for the operation of the device 1 is flush water that freely falls and accumulates in the container 14, during regular flushing of the toilet bowl. Therefore, there is no need to connect the device 1 to an external source of water, like the toilet water tank, or the mains water supply.

[0058] Referring now to Fig. 2 schematically illustrating, according to an exemplary embodiment, a front perspective view of a device for cleaning toilet bowls with a bridge in a bent state. In Figs. 1 A-B, the bridge 12 is straight, whereas in Fig. 2 the bridge 12 is bent. Thus, according to one embodiment, the bridge 12 is configured to be in a straight state, as shown in Figs. 1A-B, or in a bent state, as shown in Fig. 2. For example, on one hand, when the device 1 is presented, for example in an exhibit, or when the device 1 is packaged, the bridge 12 can be in a straight state. On the other hand, when the device 1 is installed on a rim of a toilet bowl, the bridge 12 is in the bent state, thus allowing the container 14 to be in a innerside of the toilet bowl rim, and the control unit 18 to reside on an outer side of the toilet bowl rim.

[0059] According to one embodiment, the bridge 12 is flexible. This embodiment allows the bridge 12 to shift between the straight state and the bent state. This flexibility allows bending of the bridge 12 over the rim of the toilet bowl for placing the container 14 under the rim of the toilet bowl, where flush water enters the toilet bowl, and for placing the control unit 18 over an outer surface of the rim of the toilet bowl. This flexibility also allows adjustment of the bridge 12 to any available size and shape of a rim of a toilet bowl. According to this embodiment, the bridge 12 is made of a flexible material. Any type of flexible material, from which the bridge 12 is made, is under the scope of the present subject matter, for example, but not limited to, silicon, flexible plastic, fabric and the like.

[0060] According to another embodiment, the bridge 12 is configured to adjust its length, for example to lengthen, or shorten. This embodiment allows adjustment of the bridge 12 to different sizes and shapes of toilet bowls, in order to correctly position the container 14 under the rim of the toilet bowl. Thus, according to this embodiment, the bridge is made of an elastic material that allows changing the length of the bridge 12, or, for example, the bridge 12 has a harmonica-like structure that allows the bridge 12 to lengthen or shorten.

[0061] According to one embodiment, the bridge 12 has an exposed side 12E, seen in Figs. 1A and 2, and a contact side 12C, seen in Figs. IB and 2. When the device 1 is placed on a rim of the toilet bowl in the bent state of the bridge 12, as shown in Fig. 2, the exposed side 12 E of the bridge 12 is exposed, for example to the ambient air, whereas the contact side 12C of the bridge 12 is in contact with a surface of the toilet bowl and the toilet bowl rim.

[0062] As can be seen in Figs. 1A and 2, the exposed side 12E of the bridge 12 is smooth. However, this is only an exemplary presentation of the exposed side 12E and should not be considered as limiting the scope of the present subject matter. The exposed side 12E can be in any structure. However, according to one embodiment, the contact side 12C of the bridge is rough. This embodiment allows, for example, tight fixing of the bridge 12 to a surface of the toilet bowl and of the toilet bowl rim, for example in order to prevent sliding of the device on the toilet bowl rim, especially during cleaning of the toilet bowl with the device 1. Any type of mechanism for making the contact side 12C of the bridge 12 rough is under the scope of the present subject matter. For example, the contact side 12C can be with a high friction coefficient,for example by a material with a high friction coefficient of which the contact side 12C is made. Another example, shown in Figs. IB and 2, is of a contact side 12C that comprises a plurality of protrusions 126 extending from the contact surface 12C and have a high friction coefficient that enables tight fixing the bridge 12 on the toilet bowl rim.

[0063] Returning now to Fig. 1A. According to one embodiment, the control unit 18 comprises a door 182. Opening of this door 182 gives access to a power source compartment that will be shown hereinafter.

Fig. 3 shows the control unit 18, and the second edge 124 of the bridge 12 that is attached to the control unit 18. More particularly, Fig. 3 is a front view of the interior of the control unit 18, that can be seen for example when the door 182 of the control unit 18, shown in Fig. 1A, is open. Thus, according to one embodiment, the control unit 18 further comprises a power source compartment 184 configured to house the at least one electrical power source 22. According to one embodiment, the at least one electrical power source 22 is a battery. Any type of battery is under the scope of the present subject matter, for example a disposable battery, a chargeable battery and the like. Fig. 3 shows two electrical power sources 22 in the form of two batteries 122. It should be noted that this number of electrical power sources 22 is only exemplary and should not be considered as limiting the scope of the present subject matter. Any number of electrical power sources 22 can be housed in the power source compartment 184.

[0065] Referring now to Fig. 4 schematically illustrating, according to an exemplary embodiment, a back view of an interior of a control unit. Fig. 4 shows additional components that reside inside the control unit 18, namely the pump 20 and the control electronic circuit 242 - a detailed description of it will be given hereinafter.

According to another embodiment, the holder 30 is configured to hold the tablet 35 above the level of water that is in the container 14, in a manner that allows flush water that enters the container 14 to path over the tablet 35, and dissolve some of the material of the tablet 35. According to this embodiment, the holder 30 is perforated. As a result, small amounts of the material of the tablet 35 dissolves in the flush water that passes through the holder 30 in its way into the toilet bowl. Thus, some of the material of the tablet 35 enters into the water that accumulates in the container 14 after each flush of the toilet bowl. According to yet another embodiment, the holder 30 is configured to hold the tablet 35 in a manner that allows at least partial immersion of the tablet 35 in the water that is in the container 14.
