The invention, in certain embodiments, relates to apparatuses and methods for washing hands, and more particularly, to apparatuses and methods that allow many people washing hands efficiently.
For hygienic reasons and/or for reasons of religious ritual, people of all ages need to wash their hands, for example before partaking of certain food and before prayers. For example, before a life cycle event such as a wedding, where food is served to large numbers of people, religious people are required to wash their hands and this leads to a need for large numbers of people to wash their hands all at around the same time. This causes delay and is inconvenient.
In one embodiment, an apparatus for washing hands comprises a chamber configured to hold water for washing hands, the chamber having a water outlet to drain the water out of the chamber; a vessel for holding and pouring water, at least a portion of the vessel situated in the chamber; an axle extending into the chamber and configured to attach to the vessel such that the vessel is configured to rotate relative to the axle in order to pour water out of the vessel and into the chamber; a water inlet configured to deliver water to or into the vessel, the vessel having a valve mechanism for regulating a flow of water into the vessel such that whenever a water level in the vessel reaches a certain level, the valve mechanism automatically ensures that water stops flowing into vessel, the valve mechanism including a valve connected to the water inlet, wherein the water inlet is configured to allow a constant flow of water into the vessel until the valve is closed by the valve mechanism.
In certain embodiments, the valve mechanism includes a float situated in the vessel and the valve mechanism is configured to close the valve when water in the vessel exerts an upward force on the float.
In some embodiments, the water inlet runs through the axle.
In some embodiments, at least one wall of the chamber has two apertures, each of the apertures configured to allow an individual to insert a hand into the chamber.
In some embodiments, the apparatus further comprises a vessel handle configured to extend outside the chamber for rotating the vessel on the axle from outside the chamber.
In some embodiments, the chamber has a rotatable ceiling and is configured to attach to a wall of a room such that the ceiling cannot be rotated as long as the chamber is attached to the wall of the room.
In some embodiments, the apparatus for comprises a clamp assembly for attaching the chamber to a desk.
In some embodiments, the apparatus further comprises an automated hand drying mechanism situated in or alongside the chamber. In some embodiments, the automated hand drying mechanism includes a fan configured to blow air on a user's hands when the user's hands are situated at least partly in the apertures.
In some embodiments, the apparatus further comprises a leg-activated actuator for rotating the vessel.
In some embodiments, the apparatus further comprises a first bearing assembly connecting the vessel to the axle, the first bearing assembly configured to allow rotation of the vessel relative to the axle with one particular degree of freedom of movement and a second bearing assembly configured to allow rotation of the vessel relative to the axle with a second degree of freedom.
In some embodiments, the chamber includes a ledge jutting out of a front wall of the chamber.
In another embodiment, an apparatus for washing hands comprises a vessel for holding and pouring water; an axle configured to attach to the vessel such that the vessel is configured to rotate relative to the axle in order to pour water out of the vessel and into a drainage area external to the apparatus; a water inlet configured to deliver water to or into the vessel, the vessel having a valve mechanism for regulating a flow of water into the vessel such that whenever a water level in the vessel reaches a certain level, the valve mechanism automatically ensures that water stops flowing into vessel, the valve mechanism including a valve connected to the water inlet, wherein the water inlet is configured to allow a constant flow of water into the vessel until the water inlet is closed by the valve mechanism.
In some embodiments, the valve mechanism includes a float situated in the vessel and the valve mechanism is configured to close the valve when water in the vessel exerts an upward force on the float.
In some embodiments, the water inlet runs through the axle.
In some embodiments, the apparatus further comprises a vessel handle configured to rotate the vessel relative to the axle.

These and other features, aspects and advantages of certain embodiments will become better understood with reference to the following drawings, descriptions and claims.
Various embodiments are herein described, by way of example only, with reference to the accompanying drawings, wherein:
The following detailed description is of the best currently contemplated modes of carrying out the invention. The description is not to be taken in a limiting sense, but is made merely for the purpose of illustrating the general principles of the invention, since the scope of the invention is best defined by the appended claims.
Certain embodiments of the invention generally provide a convenient and practical method and apparatus for a washing station usable by many people. Washing by pouring water from a washing vessel (as opposed to putting one's hands under a faucet) is mandatory according to certain religious rituals. Each person using the washing station need not turn on the water or turn off the water and need not move the washing vessel into position for use. This saves time, particularly when the number of people using the washing station is large. In accordance with certain embodiments, the user need only tilt the vessel (directly or indirectly such as by using an actuator). In some embodiments, even a long line of people will be able to wash hands one after the other without the tedious long wait of positioning the vessel and filling and refilling the vessel. In certain embodiments, the apparatus described herein also avoids the mess of wetness because in certain embodiments it directs the used water into a drainage floor of the chamber and because in some embodiments of the chamber the chamber includes a ledge configured to capture any water falling or spraying during the procedure of washing the hands. The apparatus is suited in certain embodiments for the handicapped, for parents helping children wash. It also can be actuated by one's leg, in some embodiments.
In certain embodiments, the apparatus for washing hands comprises a chamber configured to hold water used for washing hands. In other embodiments, there is no chamber and the apparatus may adjoin a sink or other water drainage area. If apparatus includes a chamber, the chamber has a water outlet to drain the water out of the chamber. The apparatus includes a vessel for holding and pouring water. The washing vessel is situated within the chamber although that is not a limitation (there can be no ceiling on the chamber and less than the entire vessel can be within the chamber with the rest sticking out in certain embodiments). In certain embodiments at least a portion of the vessel is situated in the chamber.
An axle extends into the chamber in some embodiments and the axle is configured to attach to the vessel or to a bearing assembly connected to the vessel such that the vessel can rotate relative to the axle in order to pour water out of the vessel and into the chamber (or if there is no chamber into a sink below). A water inlet is configured to deliver water to or into the vessel, for example by entering the vessel through a wall of the vessel, for example through the axle, or up to a valve. In certain embodiments, the vessel also has a valve mechanism including a valve connected to the water inlet. The valve mechanism is configured to close the valve and thereby block further entry of the water into the vessel whenever the water level in the vessel reaches a certain level. The term “valve” used in this patent application is a broad term that includes any kind of valve whatsoever that is configured to regulate water flow so as to block water flow in at least one mode and to allow water flow in at least one mode. The valve mechanism can comprise a float mechanism that includes a float that triggers a closing of the valve.
In certain embodiments, the water flow into a vessel is normally is a state of being “On”—that is, the water is constantly flowing into a vessel or at least towards the vessel up to a valve or a blockage point where it is blocked. The water inlet is configured to allow a constant flow of water into the vessel until the valve is closed by the float mechanism. When water is poured out of the vessel for washing and the water level in the vessel recedes, water flow into the vessel resumes and this happens automatically without the user (for example the person washing their hands) having to take any action.
The term “chamber” is a broad term that includes any container configured to hold water and can be made of any shape or material.
The principles and operation of an Assembly for Washing Vessel and Chamber may be better understood with reference to the drawings and the accompanying description.
As shown in
Apparatus 10 includes a vessel 30 inside chamber 20 configured to hold water and to pour water out when tilted (vessel is in chamber 20 in embodiments in which apparatus 10 includes a chamber 20). In one non-limiting version shown in
Vessel 30 may be any vessel suitable for holding water. Vessel 30 in certain embodiments is configured for convenient pouring water in vessel 30 out of vessel 30 onto a hand near vessel 30 by tilting vessel 30. In one embodiment depicted most easily seen in
Apparatus 10 may also include an axle 40 that extends into chamber 20 and to vessel 30 or to a bearing assembly 70 connected to vessel 30. For example, axle 40 may extend from a wall of the room that apparatus 10 is located in or may extend from behind that wall or, in cases where water inlet 50 is within axle 40, from general water piping. Axle 40 is configured to attach to vessel 30 such that vessel 30 can rotate relative to axle 40. For example, vessel 30 may rotate using bearing assembly 70 attached to axle 40 and thereby allow the user to pour water out of vessel 30 onto the user's hands. The water poured from vessel 30 typically falls into chamber 20 and typically reaches the floor of chamber 20 containing a water outlet 22 (as a result of the user pouring water from vessel 30 onto the user's hands). Axle 40 is depicted as cylindrical in the drawings, although this is not a requirement.
As seen from
Water inlet 50 may bring water up to valve 65 in some embodiments. Valve 65 may be situated inside vessel 30 or may be situated at wall 31 of vessel 30 or may be situated outside vessel 30. In
Axle 40 may be connected at a distal end of axle 40 to a wall of a room or building in which apparatus 10 is located or to water piping that extends beyond the wall of the room or building to a water source or to a main water pipe or hub.
In certain embodiments of apparatus 10, there is a mechanism 60, for example a valve mechanism 60, for regulating the flow of water into vessel 30 such that whenever the water level within vessel 30 reaches a certain height or a certain level, the valve mechanism automatically ensures that water stops flowing into vessel 30. Valve mechanism 60 may include valve 65 connected to water inlet 50. Valve mechanism 60 is typically in vessel or on vessel 30 but in some embodiments portions of valve mechanism 60 can be external to vessel 30.
In one implementation of valve mechanism 60, a sensor (not shown) along wall 31 of vessel 30 senses a height of the water level in the vessel 30 and triggers a closing of valve 65. A variety of other implementations of valve mechanism 60 are also contemplated. Closing of valve 65 may be triggered by water in vessel 30 reaching a certain level and this can be a level necessary to mechanically urge valve to close or this can be a predetermined height of the water in vessel 30, such as a certain percentage of the vessel 30 being full of water, or the trigger can be a height level of the water in vessel 30 or any of a variety of other triggers depending on the embodiment.
In one implementation of valve mechanism 60, vessel 30 comprises a float mechanism that includes a valve 65 and a float 62, the float 62 in certain embodiments situated within vessel 30, and the valve mechanism 60 is configured to close valve 65 when water in vessel 30 exerts an upward force on float 62. Float 62 is connected to valve 65, for example mechanically as shown in
One non-limiting configuration of float mechanism 60 is shown in detail in
In one non-limiting embodiment, float 62 is connected mechanically to valve 65 such that the upward force of float 62 urges a component such as valve 65 to regulate the flow of water through valve 65. In one non-limiting example shown in
In one particular non-limiting example of how this can be implemented, one of the jointed levers 64a, 64b shown in
In other embodiments, valve 65 can instead be regulated and closed to block water flow in any of a number of other mechanical ways. In still other embodiments, valve 65 can be regulated from open to closed state using non-mechanical means such as electrical, electromagnetic and/using sensors.
Thus, the height of water level in vessel 30 is regulated so as to not exceed a certain height within vessel 30. That height is pre-determined, for example by the position of float 62 relative to the floor of vessel 30 to provide enough water to be available in vessel 30 with which to wash one's hand at least once and in some embodiments enough water to wash both hands once or at least once and in some embodiments enough water to wash both hands twice or at least twice or enough to wash both hands three times (in accordance with requirements of certain religious rituals which may require washing each hand twice or three times). For example, in certain embodiments, the float mechanism 60 is configured to ensure that water fills vessel 30 until vessel 30 is at least half full or in other embodiments is two-thirds full or in other embodiments is three-quarters full or in other embodiments is at least 80% or at least 90% full or is completely full. In certain embodiments, the float mechanism 60 is configured to ensure that water fills vessel 30 until vessel 30 holds 250 cc or a particular amount that is at least 250 cc or in other embodiments holds 500 cc or a particular amount that is at least 500 cc or in other embodiments holds 750 cc or a particular amount that is at least 750 cc or in other embodiments holds a liter or a particular amount that is at least a liter or in other embodiments holds a liter and a half or a particular amount that is at least a liter and a half. Other amounts are possible and these are non-limiting examples.
Normally, water inlet 50 is configured to allow a constant flow of water into vessel 30 until water inlet 30 is closed by float mechanism 60. In other words, the flow of water is “on” all the time and is just blocked when the water level in vessel 30 reaches a certain level. This means that each person in the typically long line of people lining up to wash their hands does not teach first turn on the water (and later turn off the water so the sink does not overflow) and does not even need to position a washing vessel underneath a faucet. In addition, the apparatus 10 is configured to ensure that an entire washing station is in place and ready for use by large numbers of people whenever necessary. In embodiments where apparatus 10 is attached to the wall, the washing vessel does not have to be guarded to make sure it is not lost or taken away by a child for example. In many wedding halls and restaurants, the washing vessel is tied to the sink area by a chain whereas apparatus 10 alleviates the need for this.

In accordance with certain embodiments, apparatus 10 may have an actuator 21 facing outward from outer wall of chamber 20 with which to cause vessel 30 to tilt for washing. This can be useful when a parent is assisting a child in washing hands or for people with certain handicaps. The child sticks their hands into apertures 24, 26 and the parent activates, for example turns, the actuator 21. In one non-limiting implementation of this, actuator 21 comprises a handle 21 configured to jut out of chamber 20 for rotating vessel 30 relative to axle 40 from outside chamber 20. In one example, the handle 21 is a simple knob 21 that can be turned in either direction to tilt vessel 30 left or right. Other ways of actuating the tilting of vessel 30 are also possible. Another way in which tilting vessel 30 can be actuated is by a leg-actuated lever 99 configured to rotate vessel 30 as shown schematically in
In certain embodiments, chamber 20 has a ceiling, for example a rotatable ceiling 28 (
Chamber 20 may be situated against a wall of a room or even behind the wall. In either case, the user sticks his or her hands into the apertures 24, 26 of chamber 20 to wash their hands.
In certain embodiments, for example in accordance with one non-limiting implementation shown in dotted lines in
One embodiment of apparatus 10 does not include any chamber 20.
In the embodiment of apparatus 10 that does not include any chamber 20, instead of chamber 20, the apparatus 10, and in particular axle 40 of apparatus 10, attaches to any infrastructure such as a wall having a sink in front of it. In that case, the water that pours out of vessel 30 falls into the sink (external to apparatus 10) instead of into a chamber 20 of apparatus 10 after the user washes his or her hands. Accordingly, in this embodiment, apparatus 10 for washing hands, comprises vessel 30 for holding and pouring water, axle 40 configured to attach to vessel 30 such that vessel 30 is configured to rotate relative to axle 40 to pour water out of vessel 30 and into a drainage area external to the apparatus 10, a water inlet 50 configured to deliver water to or into the vessel 30. Vessel has a mechanism 60 such as a valve mechanism for regulating a flow of water into vessel 30 such that whenever a water level in vessel 30 reaches a certain level, the valve mechanism 60 automatically ensures that water stops flowing into vessel 30. Valve mechanism 60 may include a valve 65 connected to water inlet 50. Water inlet 50 is configured to allow a constant flow of water into vessel 30 until water inlet 50 is closed by valve mechanism 60.
In one implementation, axle 40 is configured to attach on one of its ends to infrastructure such as a wall external to apparatus 10, the axle 40 also configured to attach on the other (proximal) end to vessel 30 such that vessel 30 is configured to rotate relative to the axle 40 (for example using bearing assembly 70 connected to axle 40) in order to pour water out of vessel 30 (and into a sink or other suitable drainage area external to apparatus 10, for example below vessel 30). Apparatus includes a water inlet 50 configured to extend into vessel 30 through a wall 31 of vessel 30. Water inlet 50 may comprise a tube or pipe inside axle 40 or may be situated external to axle 40. Instead of a separate tube or pipe inside axle 40, water inlet 50 may just comprise the inner space defined by the inner walls of axle 40. Vessel 30 may also comprise a valve mechanism 60 configured to regulate flow of water through water inlet 50, for example using valve 65, and thereby block further entry of the water into vessel 30 when a water level in vessel 30 reaches a certain level. For example, valve mechanism 60 may comprise a valve 65 and a float 62. Water inlet 50 is configured to allow a constant flow of water into vessel 30 until the water inlet is closed by the float mechanism 60.
In the embodiment where there is no chamber 20, apparatus 10 may comprise any suitable version of its components (including but not limited to any suitable version of any portion of vessel 30, axle 40 water inlet 50, mechanism 60 or valve mechanism 60) described in relation to the embodiment of apparatus 10 that does include chamber 20. For example, apparatus 10 may include an actuator 21 such as a handle extending outwardly from vessel 30, for example from a front of vessel 40, that allows a user to rotate vessel 30 relative to axle 40 without having to contact vessel 30 directly. In another example, apparatus 10 may include a clamp assembly configured to attach apparatus (without a chamber) to a desk (for example by attaching to axle 40). In another example, apparatus 10 includes the hand drying mechanism which for example is attached to axle 40 or to a nearby wall or other infrastructure.
In some variations, apparatus 10 is configured to be attached to a desk using a clamp assembly. As shown in
For embodiments in which apparatus 10 includes chamber 20, apparatus 10 may also be combined with the clamp assembly 151 shown in
