-
FIG. 1 pictorially illustrates a bathroom having a flush toilet in which a toilet-disinfectant dispenser is installed, according to one embodiment of the invention. -
Dispenser 30 is attached to the rim of thetoilet bowl 14 by aclip 20. - Handle 10 of
dispenser 30 activates dispension of the disinfectant. When the toilet'sseat 16 is placed down or upon sitting on seat 16 (depending on the design thereof),seat 16 pushes handle 10 ofdispenser 30 downwards, thereby activating the dispension of disinfectant intotoilet bowl 14. - The dispenser can be designed to dispense the substance upon placing the seat on the handle. Alternatively, the dispenser can be designed to dispense the substance only when a user sits on the toilet seat. When employing a spring, the strength of the spring may determine how the dispensing is activated, upon applying a weight of a toilet seat, or upon applying the weight of a user.
- The handle is actually an activator of the dispenser. As will be detailed hereinafter, the activator may be also a circuitry which employs a sensor for sensing presence of a user at the toilet bowl, and so on.
- Thus, according to this embodiment, the operation of dispensing disinfectant into the toilet bowl takes place a “short time” before the waste falls the bowl. As such, when the waste is dropped down, the disinfectant already is present in the toilet bowl, and as a result, the operation of eliminating organisms producing stench is more effective and faster than in any other prior art technology wherein the dispensing operation takes place after the waste has dropped into the toilet bowl.

FIG. 2 is a zoomed view, which schematically illustrates the toilet-disinfectant dispenser ofFIG. 1 . -
FIG. 3 is an exploded view from the front of the toilet-disinfectant dispenser ofFIG. 1 . -
FIG. 4 is an exploded view from the back of the toilet-disinfectant dispenser ofFIG. 1 . - Generally, the toilet-
disinfectant dispenser 30 is composed of a container (whose walls are marked by numeral 32) for storing the disinfectant substance, avanes wheel 48 that rotates inside the container, and a unidirectional bearing, which rotates the vanes wheel 48 in one direction.Container 32 comprises anoutlet 41 through which the substance is released from the container, and ahandle 10 which rotates the unidirectional bearing, thereby dispensing the disinfectant substance stored therein. -
Element 34 is used as a chassis to the construction. Anaxle 44 forwheels chassis 34. Also attached to thechassis 34 is alid 42, whose role is described hereinafter. -
Wheel 48 comprises acylinder 38 on one side thereof (better seen inFIG. 3 ) and a plurality ofvanes 40 on the other side. - A
handle 10 is attached to thewheel 36. -
Wheel 36 is a cogwheel in which the cogs are in the interior part thereof. - Upon turning
handle 10 down,cogwheel 36, which is attached to handle 10, gripscylinder 38 and as such, rotateswheel 48 to whichcylinder 38 is attached (or is a part of). Aswheel 48 rotates, the substance within the toilet-disinfectant dispenser falls down throughopening 41. If opening 41 is positioned above a toilet bowl, the substance falls into the bowl. -
Wheel 48 is used also as a lid to thewalls 32 of the disinfectant container.Wheel 48 also comprisesvanes 40, which turn to the interior side ofcontainer 32. Aswheel 48 rotates,vanes 40 blend the disinfectant substance stored within the container, the walls of which are marked as 32, thereby assuring that the dispensed quantity of substance is substantially constant.Element 42 is a lid the role of which is explained inFIGS. 6 a and 6 b and the description thereof. -
FIG. 5 is a sectional view which schematically illustrates the structure of a unidirectional bearing that can be employed in embodiments of the invention. - The unidirectional bearing is used to rotate
wheel 48 whenhandle 10 is pushed downwards, and makes an idle move in the opposite direction. Presently, unidirectional bearings are well known in the art. - The unidirectional bearing illustrated in
FIG. 5 comprises: acylinder 48; acogwheel 36 the cogs of which are saw-like; androllers 46. The cogs ofcogwheel 36 are in the form of a saw cogs. Sincewheel 36 comprises saw-like cogs, the space betweenwheel 36 andwheel 48 along a cog is gradual, and reaches to a minimum at the tip of a cog. InFIG. 5 , the cogs are on the interior side ofcylinder 36. However, alternatively, the cogs may be on the exterior side ofwheel 48. In such a case, the internal diameter ofcylinder 38 must be greater than the external diameter of thecogwheel 36. - When cogwheel 36 rotates in direction A,
rollers 46 roll towards a narrower space betweencylinder 38 andcogwheel wheel 36. Asrollers 46 advance,cogwheel 36grips cylinder 38 tighter, and at acertain point cylinder 38 rotates along with the rotation ofcogwheel 36. - When cogwheel 36 rotates in the opposite direction, i.e., direction B, the grip of
cogwheel 36 loosens, and when aroller 46 reaches to edge 37 of a cog, theroller 46 is dragged. In other words,cogwheel 36 rotates freely aroundcylinder 38 in the B direction. -

According to this embodiment of the invention, anadditional container 62 is attached to the construction ofdispenser 30.Container 62 may include a different substance which is gradually washed away (through opening 64) with the water of the toilet thereof. The substance stored incontainer 62 may be a fragrance, a substance which may react with the disinfectant substance stored in the container (the walls of which are marked by numeral 32) and therefore stored in a different container, etc. The substance to be stored incontainer 62 may be in the form of a solid object such as tablet(s), powder, liquid, and so forth. -
FIG. 9 is a sectional view of a bathroom in which a toilet disinfectant dispenser is installed, according to another embodiment of the invention. - According to this embodiment, the dispenser is installed above the toilet bowl, in contrast to the inside of the toilet bowl. This enables a user to activate the dispensing independently from the toilet seat. The toilet disinfectant dispenser is located near the
water activator 8 of the toilet. Apipe 18 connects the substance outlet of thedispenser 30 withpipe 24 through which water is conveyed totoilet bowl 14. -
FIG. 10 illustrates a bathroom equipped with the toilet disinfectant dispenser ofFIG. 9 . -
FIG. 11 pictorially illustrates a bathroom having a flush toilet in which a toilet-disinfectant dispenser is installed, according to another embodiment of the invention. -
FIG. 12 is a zoomed view which schematically illustrates the toilet-disinfectant dispenser ofFIG. 11 . - Each of
FIGS. 13 and 14 is exploded view from a different angle of the toilet-disinfectant dispenser ofFIG. 11 . -
FIGS. 15 a and 15 b schematically illustrate the dispensing operation carried out by the dispenser illustrated inFIG. 11 . - From the structural point of view, the dispenser illustrated in
FIGS. 11 to 15 i comprises a cylindrical container (composes ofmembers 92 and 84) inside which acylinder 96 rotates around an axle 80 (which is a part of member 92),cylinder 96 may be rotated by ahandle 10 connected thereto; and a “rack” 88. - At State A, which is illustrated in
FIG. 15 a, opening 90 and ofrack 88 andopening 98 ofcylinder 96 overlap. In this way, the disinfectant substance stored within the container fills the cell generated byopenings state opening 94 of the container does not overlapopenings - At State B, which is illustrated in
FIG. 15 b, opening 98 ofcylinder 96 overlaps opening 94, resulting with pouring the substance enclosed in opening 98 out of the dispenser. - Upon releasing
handle 10, a spiral-spring 86returns cylinder 96 to State A. - In other words, the disinfectant substance that fills opening 90 in State A is dispensed in State B. In State A
opening 98 is exposed to the disinfectant substance within the container, and in State B the substance within opening 98 is poured out throughopening 94. InState B rack 88 is used as a lid to opening 98, thereby preventing from the rest of the substance enclosed within the container to be poured out. - It should be noted that although the activator is preferably a mechanical device, since it does not have to use electric power; the activator may also employ electric power. When electric power is used, the activator may use a sensor. A simple sensor may be a contact sensor. For example, one contact of a circuit is deployed on the toilet seat, and the other on the lavatory. When the seat is placed down, the contact between the contacts closes a circuit which dispenses one portion of the disinfectant substance into the toilet bowl.
- According to one embodiment, the sensor is a strain sensor, which indicates when a pressure of a certain level and higher is applied on the sensor. Thus, a certain pressure (e.g., the weight of a seat, the weight of a user) is applied, one substance portion is dispensed.
- According to another embodiment, the sensor is a based on infrared technology, such as the sensors applied in taps of toilet rooms which pour water upon sensing presence of an object underneath the tap. Such a sensor may sense presence of a user near the toilet bowl, falling waste inside the bowl, and so on.
- According to one embodiment of the invention, the toilet seat and/or lid is used as a container of the dispenser. In this case the container may be refilled. Actually, the entire dispense may be embedded in a toilet seat/lid.
