This invention relates to toilet apparatus, to a cleaning or dispensing device for use with toilet apparatus and to a method of using a dispensing or cleaning device.
Although the following description refers almost exclusively to conventional toilet apparatus having a toilet bowl and toilet cistern associated therewith, it will be appreciated by persons skilled in the art that the toilet apparatus of the present invention could be used with any type of toilet or bathroom apparatus, such as a urinal, bidet, non-conventional toilet and/or the like.
A conventional toilet typically includes a toilet bowl with a toilet lid and/or seat associated with an upper surface thereof to allow a user to sit comfortably on the same in use. A cistern is connected to the toilet bowl to allow water contained in the cistern to flow into the toilet bowl following a user actuated flush to clear the toilet bowl after use. Clearance of the toilet bowl using the flushing water takes place via a siphon mechanism. The water typically enters the toilet bowl from the cistern at the same place or places after a toilet flush. The flow of water over the interior surface of the toilet bowl following a flush does provide a certain level of cleaning of the interior surface of the toilet bowl. However, most flush systems allow the flow of flushing water over a fixed part only of the toilet bowl and so there is normally at least part of the toilet bowl which is not cleaned after flushing. Furthermore, the water entering the toilet bowl from the cistern may not be of sufficient pressure or quantity to provide an adequate cleaning effect.
In order to overcome the abovementioned problem, it is known to provide a toilet brush in a bathroom or toilet environment to allow a user to specifically clean part or parts of an interior surface of a toilet bowl after use. The toilet brush is typically located in a container adjacent the toilet when not in use and has a handle attached to the brush to allow a user to manipulate the same. However, a problem with toilet brushes is that they are unhygienic, often produce drips on the toilet or surfaces surrounding the toilet in use, they are not aesthetically pleasing and often can look unsightly after use.
GB2427124 discloses a spray jet cleaner for cleaning a toilet bowl. The cleaner is hung next to the toilet when not in use and interchangeable venturi heads are provided for use with the cleaner to provide different spray patterns.
GB2404351 discloses spray apparatus for cleaning toilet bowls including a spray head connected to a water hose. The spray head includes a casing having an inlet, an outlet and a chamber within the casing to receive a cleansing medium. Water flows over the cleansing medium in use. A removable cover is provided to allow access to the chamber and a depressible hand operated valve allows user control of the flow of water through the spray head.

A further arrangement of fluid outlet nozzles is shown in
The body portion 18 has a channel 23 passing through the interior thereof and a first end 25 of the channel communicates with the nozzles 30, 32 at first end 19 of the water dispenser, and a second end 27 of the channel communicates with the water conduit 24. As such, with the valve arrangement 26 in an “on” condition, water can pass from the mains water conduit 14, along conduit 24, through the channel 23 defined in body portion 18 and out through the nozzles 30, 32.
Control means 20 can be used to control the flow of water through the water dispenser 16 by opening and closing channel 23. Further control means can be used to adjust the pressure of the water flowing through the nozzles 30 or 32 and/or can be used to adjust which of the nozzles 30, 32 the water is dispensed from. For example, a user may only require water to be dispensed via the central nozzle 30. Alternatively, the nozzle may require water to be dispensed from all the nozzles 30, 32.
In use of the device in
The conduit 24 is typically of such a length to allow the elongate body 18 of the dispenser to be moved close to and preferably inside the toilet bowl 4. In addition, conduit 24 is typically substantially flexible to allow the dispenser to be easily manipulated and moved to any required angle relative to toilet bowl 4. This allows accurate cleaning to be undertaken.
It will be appreciated that in some types of toilet systems, the water dispenser can be used in place of a conventional toilet flush. However, in a preferred embodiment, the water dispenser is used in addition to the conventional toilet flush.
Support means in the form of a holder device 28 can be mounted on the wall adjacent the toilet for holding the water dispenser 16 in an “out of use” or storage position. The holder device 28 typically maintains the dispenser with the first end 19 uppermost to ensure that any residual water left in the body portion or conduit 24 after use does not spill out onto the floor surrounding the toilet. However, it will be appreciated that the holder device can be in any suitable form, such as a hook, clip, friction fit, inter-engaging member and/or the like and can hold the water dispenser in any suitable manner or orientation. In addition, to prevent further spillage of water or fluid from end 19, valve 51 blocks the flow of water when the water supply is turned off by valve 49.
The elongate body portion 18 can be provided in two parts; a top part 18a and an intermediate part 18b, the ends 34 of which are detachably attached together via a rotatable mounting in the form of a complementary screw thread arrangement 36. The two parts 18a, 18b can be separated via unscrewing of the screw thread arrangement. End 37 of intermediate part 18b is detachably attached via a rotatable mounting in the form of a complementary screw thread arrangement 36 to end 39 of base part 41, at least a part of base part 41 forms control means 20. Water inlet means 22 can also be detachably attached via a rotatable mounting in the form of a complementary screw thread arrangement to end 45 of base part 41 via end 43. Thus, the water dispensing head in the illustrated embodiment comprises four parts which are detachably attached to each other via rotatable mountings, thereby allowing easy dismantlement for cleaning and/or repair. It will be appreciated that fewer or greater number of parts can be provided to form the dispensing head if required.
One or more cleaning products, disinfectants, odourous products and/or the like can be inserted in or in association with the fluid channel 23 at any suitable location. The products can be easily inserted by unscrewing any suitable parts of the dispensing head and locating the product in channel 23.
In the illustrated embodiment, a cartridge 38 containing a disinfectant can be located in the channel 23, as shown by arrow 39 in
The water dispenser can be formed from any suitable material, such as plastic, metal, rubber and/or the like. The dispenser can also be of any suitable size, shape and/or design. Preferably the dispenser is aesthetically pleasing and can be matched to any interior design within the bathroom or toilet in which it is to be located.
Gripping means in the form of knurled exterior surfaces 47 can be provided on top part 18a and base part 41 to allow a user to easily grip the exterior surface of the dispensing head. Gripping means could be provided at any suitable location and/or in any form on the dispensing means.
A flow control valve 49 is provided in base part 41 forming part of the control means for allow control of the flow of fluid through dispensing head 16. A pressure valve 51 is provided in top part 18a to allow control of the fluid pressure being dispensed from the dispensing head. Operation of the valves can be via rotation of one or more parts of the device in a suitable manner. Thus, for example, partial or a small amount of rotation of one or more of the parts may adjust the valve or valves.
Referring to
A valve closure element 66 is movably mounted in valve housing 60 via screw threads 68 which are complementary to screw thread portions provided on the interior walls of valve housing 60. The screw threads allow valve closure element 66 to be rotatably moved longitudinally of valve housing 60 and thus of base part 41. Thus, rotation of base part 41 with respect to housing part 18b causes closure element 66 to be rotated with respect to valve housing 60 between open and closed positions. Closure element 66 can move between ends 80 and 82 of valve housing 60 in a reciprocating manner when rotated.
End 76 of closure element 66 is attached to a valve seat component 74. When the valve 49 is in a closed position, the valve seat 74 engages with or in a channel defined in water inlet means 22, as shown in
When the valve 49 is in an open position, the valve seat 74 is moved a spaced distance apart from the water inlet means 22 and end 78 of the closure element 66 is moved towards end 82 of valve housing 60. Fluid flows through the water inlet means 22, around the external surface of end portion 80 of valve housing 60. The water is prevented from flowing towards opposite end 82 of valve housing 60 due to sealing washers 69. As such, the water passes through fluid apertures 65, into the interior channel of valve housing 60 and along the interior channel defined in base part 41.
When the valve 49 is in a closed position, the valve seat 74 engages with the water inlet means 22 and end 78 of closure element 66 is moved towards end 80 of valve housing 60. Water flows through water inlet means 22 but cannot pass valve seat 74.
