Description:

TECHNICAL FIELD

The present invention relates to a device for selecting a drainage outlet for draining wastewater. In one particular form, the device includes a first drainage outlet and a second drainage outlet, wherein the device allows selection of one of the drainage outlets for draining the wastewater. The present invention also provides a kit for assembling the device, and a method for operating the device

BACKGROUND ART

Wastewater generally includes dish, shower, sink, and laundry water. A proportion of this water can be reused for other purposes, such as landscape irrigation.

A number of greywater systems are known which divert portions of wastewater for reuse, These systems are installed outside a domestic house, such as installing the system to an existing wastewater pipe, or are at least installed a significant distance from devices which output wastewater (herein referred to as “wastewater devices”) such as showers, sinks, washing machines, basins, baths and the like.

A number of these systems include a valve which is operated by the user to select whether the wastewater is to be reused or to be disposed. It is generally inconvenient in particular situations for the user to exit the domestic house or travel a significant distance from the particular wastewater device in order to operate the valve prior to using the wastewater device.

Furthermore, it is disadvantageous for the user to have to remember to return to the valve after using the wastewater device in order to actuate the valve such that wastewater is not reused or disposed incorrectly.

Additionally, whilst the system diverts all incoming wastewater for reuse, blackwater output devices may also be simultaneously operational, and as such the blackwater received in these systems may be incorrectly reused.

Therefore, there exists a need for a device which can be operated by a user whilst using a wastewater device, which addresses or at least ameliorates problems inherent in the prior art.

The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavor to which this specification relates,

MODES FOR CARRYING OUT THE INVENTION

The following modes, given by way of example only, are described in order to provide a more precise understanding of the subject matter of a preferred embodiment or embodiments.

FIG. 1 illustrates an example of a packaged kit 10 for assembling a device 5 for selecting a drainage outlet 7, 8 for draining wastewater. As further shown by the exploded diagram of FIG. 6, the kit includes a shell 20, a trough 30, a panel 25, a selection means 16, and a grate 35. The kit can optionally include a lid (visible in FIG. 1) and a surround element 40. The kit 10 call be packaged such that the shell 20 and lid 85 contain the remaining components of the device 5 such that a kit 10 is relatively compact in a packaged state.

When the device 5 is assembled (as will be discussed in detail later), the device 5 includes a surface having drainage outlets 7, 8 including a first drainage outlet 7 and a second drainage outlet 8, and a selection means 16 which is actuable to allow selection of one of the drainage outlets 7, 8 for draining the wastewater.

The selection means 16 allows a user to select one of the drainage outlets 7, 8 to be used for draining the wastewater. In one form, one of the drainage outlets 8 drains the wastewater for reuse whilst the other drainage outlet drains the wastewater for disposal 7. The device 5 in this form can be configured to allow the user to select a drainage outlet 7, 8 to drain the wastewater in accordance with the quality of the wastewater, such that the wastewater can be reused or disposed.

The device 5 generally includes a mounting means 20 for mounting the apparatus adjacent to a receptacle 200 for receiving the wastewater, as shown in FIG. 59. The receptacle 200 can include a shower, a bath, a basin, a sink or any other device (generally domestic) which outputs wastewater.

The device 5 advantageously allows actuation of the selection means 16 whilst the receptacle 200 is in use by a user to thereby drain the wastewater from the receptacle 200. The mounting means 20 allows the device 5 to be mounted immediately adjacent the receptacle 200, or at least partially within the receptacle 200 such that the selection means 16 is advantageously actuable by a user from within the receptacle 200,

In one form, the device 5 can be provided as a drain for a shower. In use, the user may be showering using shampoo, and thus the user may actuate the selection means 16 whilst showering such that the wastewater is diverted to the first drainage outlet 7 for disposing of the wastewater. Whilst the user is not using shampoo, the user may actuate the selection means 16 whilst showering such that the wastewater is diverted to the second drainage 8 outlet allowing for the reuse of the wastewater, such as for irrigation.

FIGS. 2A and 2B show isometric drawings of the device 5 which can be formed from the above mentioned kit 10. Furthermore, FIGS. 3A and 3B show a general cross-sectional view of the operation of the device 5 formed from the above mentioned example kit 10.

In particular, as shown in FIGS. 3A and 3B, the shell 20 supports the trough 30 located within the shell 20, wherein outlets 71, 72 of the shell 20 are aligned width drainage outlets 65, 66 of the trough 30. The panel 25 is then located to rest on a support section 31 of the trough 30. The surround element 40 is placed, preferably mortared, on the flange portion 67 of the trough 30, as shown in FIGS. 60, 61, 62 and 63. The surround element 40 is substantially flush in height with the grate 35 and adjacent material such as tiles on the shower floor or the like. A gap can exist between the perimeter of the surround element 40 and the grate 35.

The grate 30 is then positioned on the flange portion 67 of the trough 30 such that the height of the grate 30 is flush with the surround element 40. As described in later detail, the grate 35 can be flipped over such that the grate 35 can accommodate timber slates, tiles, pebbles. The selection means 16 includes an actuation surface 15 and a selection panel 45 which is placed adjacent the grate 35 such as to abut the grate 35, The selection means 16 is operably connected to a portion of the panel 25 such that when the selection means 16 is actuated between first and second selection positions, the panel 25 pivots between first and second positions, allowing wastewater to drain to one of the drainage outlets 7, 8.

FIGS. 3A and 31 show a general functional operation of the device represented in FIGS. 2A and 2B.

In particular, as shown in FIG. 3A, when the selection means 16 is actuated to a first selection position, the panel 25 pivots to a first position such that the panel 25 is angularly tilted relative to the horizontal. When wastewater flows over the grate 35, the wastewater flows through the holes of the grid 36 and fall onto the panel 25 placed in the first position.

Due to the panel 25 being tilted and positioned in the first position, the wastewater is gravity fed (illustrated by arrow 75) along the panel 25 to apertures 27 located at a first end region 26 of the panel 25 where the wastewater is drained therethrough and falls into a first end of the trough 30 where the first drainage outlet 7 is located. Generally, when the selection means 16 is actuated to the first selection position, and the panel 25 is in the first position, the wastewater which is drained away is disposed.

In FIG. 33, the selection means 16 is actuated to the second selection position, wherein the actuation causes the panel 25 to be placed into the second position by pivoting the panel 25 about a pivot point such that the angular tilt of the panel 25 alters.

As wastewater falls onto the panel 25 via the grate 35, the wastewater flows in a different direction (illustrated by arrow 80) to that shown in FIG. 3A, wherein the wastewater on the panel flows to a second end region 26′ of the panel 25. Apertures 27′ in the second end region 26′ of the panel 25 allow the wastewater to flow therethrough and fall into a second end of the trough 30 where the second drainage outlet 8 is located for draining the wastewater Generally, when the selection means 16 is actuated to the second selection position, and the panel 25 is in the second position, the wastewater is drained away to be reused.

As can be seen from FIGS. 3A and 3B, the actuation of the selection means 16 to the first selection position or the second selection position causes the panel 25 to move between a first position and a second position which subsequently causes the wastewater to be drained to one of the drainage outlets 7, 8 according to the selected position of the selection means 16.

Each of the above-mentioned components of the device 5 will now be described in more detail below,

Selection Means

FIGS. 7 and 8 show an example of components forming the selection means 16. In particular, FIG. 7 shows an exploded diagram of an example of a spring loaded mechanism 50 for moving and biasing the selection means 16 between the first selection position aid the second selection position.

The spring loaded mechanism 50 can include a cover 100, a shaft 90, a spring 95, a ring element 105, and a screw 160. The shaft 90 is inserted and received in a void of the cover 100 The screw 160 releasably holds the shaft 90 in the void of the cover 100.

The spring loaded mechanism 50 is connected to an actuating surface 15 of the selection means 16, such as a surface of a button, as shown in FIG. 8. As also shown in FIGS. 49 to 54, the spring 95 rests within a void of the button 16, wherein a first terminal coil of the spring 95 rests against an inner surface of the void and a second terminal coil of the spring 95 rests against the shaft 90 and cover 100. The void of the button 16 including the spring 95 is operably connected to the shaft 90 and cover 100 such that when a force is applied to the actuating surface of the button 16, the spring loaded mechanism 50 moves between an extended position and a compressed position.

When the spring loaded mechanism 50 moves between the extended position and compressed position, the actuating surface of the button 16 moves between a raised state and a depressed state, as shown in FIGS. 2A and 2B respectively. Generally, actuation of the button 16 to the second selection position causes the button 16 to be in a depressed state, and actuation of the button 16 to the first selection position causes the button to remain in an elevated state.

The spring loaded mechanism 50 is generally engageable with an engagement section 60 of the trough 30. Generally, the ring element 105 can engage a hook component of the spring mechanism 50 and an end of the shaft 90 to facilitate the elevation and depression of the button 16. The cover has a threaded base which is received ill the engagement section 60 which includes a cooperating thread.

Due to the option of the device 5 being used as a drain in a shower 200 or the like, it is preferable that the selection means 16 is actuable with a user's foot so as to restrict ally bending motion by a user. The actuation surface 15 can include visual indicia 140 indicative of the button 16 being actuable with a user's foot. The visual indicia 140 may also be further able to facilitate traction between the user's foot and an actuation surface of the button 16 which is advantageous when the user's foot may be wet.

As shown in FIGS. 3A and 3B, the spring loaded mechanism 50 of the selection means 16 is engaged with a portion of the panel 25 such that when the selection means 16 is actuated, the spring loaded mechanism 50 moves between an extended position and a compressed position causing pivotal movement of the panel 25 between the first position and second position.

As shown in FIGS. 40 to 43, the selection means 16 can include a selection means panel 45 which receivably surrounds the actuation surface 15 of the selection means 16. The selection means panel 45 is positioned so as to abut an end of the grate 35. The panel 45 has a void 47 which close-fittingly receives the actuation surface 15 of the selection means 16.

The panel 45 can include visual indicia 46 indicative of the first selection position and second selection position of the selection means 16. The visual indicia 46 associated with the first selection position is generally indicative of the wastewater being drained through the first drainage outlet 7 when the selection means 16 is positioned in the first selection position, and the visual indicia 46 associated with the second selection position is generally indicative of the wastewater being drained through the second drainage outlet 8 when the selection means 16 in positioned in the second selection position.

Panel

The panel 25 is generally configured to restrict the wastewater draining through at least some of the drainage outlets 7, 8 and/or facilitate the wastewater to drain through at least some of the drainage outlets 7, 8. As shown in FIGS. 3A and 3B, the panel 25 moves between a first position, wherein the wastewater is able to drain through the first drainage outlet 7, and a second position, wherein the waste-water is able to drain through the second drainage outlet 8, wherein the movement of the panel 25 is in accordance with the actuation of the selection means 16.

The movement of the panel 25 can include a pivotable movement, such that actuation of the selection means 16 causes the panel 25 to pivot between the first position and the second position. The pivot points of the pivotal motion of the panel can include the support section 31 located at the top of the trough 30, as shown in FIG. 27. Alternatively, it is envisaged that a portion of the raised section of the trough 55 that can be in contact with the panel 25 such that the panel 25 pivots about the raised section 55,

The first position and the second position of the panel 25 can include the panel 25 being angularly titled as shown in FIG. 3A and 3B to a first angle and a second angle respectively, thereby urging wastewater in contact with the panel to flow toward a pivoting end region 26, 26′ of the panel 25, wherein each pivoting end region 26, 26′ is positioned adjacent to one of the drainage outlets 7, 8.

As shown in FIGS. 29 to 32, each end region 26, 26′ of the panel 25 includes apertures 27 which allow wastewater in contact with the panel 25 to drain toward one of the drainage outlets 7, 8 of the surface in accordance with the actuation of the selection means 16.

As shown in FIG. 32, each aperture 27 includes an elevated rim 122 relative to the panel 25. The rim 122 a similar profile to that of a hole of a cheese grater. The rim 122 includes an irregular tilt relative to the panel 25 so that the rim 122 includes a first section 123 which is elevated compared to a second section 121 of the rim 122. When the panel 25 is tilted, wastewater which first comes into contact with the first section 123 of the rim 122 is substantially drained through the aperture 27 toward one of the drainage outlets 7, 8 and wastewater which first comes into contact with the second section 121 of the rim 122 is substantially restricted from draining through the aperture 27. This is generally known as the “tea-pot effect” where due to pressure differences between the relevant sections 123, 121 of the aperture 27, the wastewater is permitted or restricted from draining through the apertures 27.

In this configuration, the apertures 27 positioned adjacent the first drainage outlet 7 can be configured to substantially restrict wastewater in contact with the panel 25 to drain toward the first drainage outlet 7 when the panel 25 is positioned in the second position. Additionally, the apertures 27 positioned adjacent the second drainage outlet 8 can be configured to substantially restrict wastewater in contact with the panel 25 to drain toward the second drainage outlet 8 when the panel 25 is positioned in the first position.

As shown in FIGS. 29 and 30, the panel 25 includes one or more tabs 28 which engage the support section 31 of the trough 30, wherein actuation of the selection means 16 can cause pivotal movement of the panel 25 about the engaged support section 31. In an additional or alternative form, the panel 25 can rest against the raised section 55 of the base portion of the trough 30, wherein actuation of the selection means 16 causes pivotal movement of the panel 25 about a portion of the raised section 55 that can be in contact with the panel 25.

Trough

FIGS. 21 to 28 show an example of the trough 25. In one embodiment, the surface of the device 5 is a portion of a trough 25. Generally, the surface is a base portion of the trough 25. The trough 25 includes the first drainage outlet 65 and second drainage outlet 66.

As shown in FIGS. 22 and 27, the base portion includes a raised section 55, wherein the first drainage outlet 65 and the second drainage outlet 66 are located on opposing sides of the raised portion 55, The raised portion 55 facilitates separation of the wastewater which flows from the panel 25 toward the surface. Additionally or alternatively, the portion of the raised section 55 in contact with the panel 25 can serve as a pivot point of the pivoting movement of the panel 25.

As shown in FIGS. 25 and 27, the trough 25 includes a support section 31 for pivotally supporting the tabs 28 of the panel 25.

As shown in FIGS. 22 and 23, the base portion of the trough 25 includes an engagement section 60 which engages an end of the spring loaded mechanism 50 of the selection means 16.

As shown in FIGS. 25 and 28, the trough includes a flange portion 67 which is able to support the surround element 40 which is positioned thereupon.

The shell 20 generally includes a first shell outlet 71 for being in fluid communication with the first drainage outlet 65 of the trough 30, and a second shell outlet 72 for being in fluid communication with the second drainage outlet 66 of the trough 30, Generally, the first and second shell outlets 71, 72 coaxially align with the first and second outlets 65, 66 of the trough 20 when the trough 30 is received within the shell 20.

Grate

FIGS. 35, 36A, 36B, 37A, 37B, 38A, 38B, 39A and 39B show an example of the grate 35 for the device 5.

In particular, the grate 35 includes holes 36 provided therethrough to permit wastewater flowing over the grate 35 to flow through to the panel 25, The holes 36 can be positioned randomly over the grate 35. The grate 35 is a self-draining surface that allows wastewater to dissipate faster than a traditional round 100 mm drop-in grate due to the elongate surface area of the grate 35. The holes 36 are configured to allow the wastewater to flow therethrough, however, are configured to restrict appendages of children becoming caught therein.

As shown in FIGS. 37A, 37B, 38A and 38B, the grate 35 can include legs 39 which extend from the grate surface 35, Each leg 39 can include provisions 38. The protrusions 38 can be formed in the grate using a metal pressing process if the grate 35 is made from metal. Neighboring protrusions 38 define a recess, allow material such as tiles, timber, stone and pebbles to be placed in the recess and over the grate 35, allowing for alternate aesthetic appearances of the device 5 when installed, The protrusions 38 also define a gap between neighboring tiles, timber, stones or pebbles such that the water can flow through the gaps defined by each protrusion 38 to the grate surface 35 below,

In the instance when tiles, timber, stone or pebbles are not to be accommodated in recesses of the grate 35, the grate is orientated in a first position as shown in FIG. 37A such that the legs protrude 39 downwards relative to the grate surface 35. However, if tiles timber, stone and/or pebbles are to be placed over the grate 35, the grate 35 is orientated in a second position (as illustrated in FIG. 38A) by flipping over the grate 35 (ie 180 degree rotation) such that the opposing side of the grate surface 35 is facing upwards and that the legs extend 39 upwards from the grate surface 35. In this second position, the tiles, timber, stone or pebbles can be placed in the recesses defined by the protrusions 38 in the legs 39 of the grate 35.

Each leg can also include a curved section 37 as shown in FIG. 39B. When the grate 35 is positioned in the second position, and the tiles, timbers, stones or pebbles are positioned between neighboring protrusions 38, the tiles, timber, stones or pebbles can rest against the curved recess 37. This curved recesses 37 in each leg 39 prevent the tiles, timber, stones or pebbles from resting against the grate 35, and therefore preventing any blockage the holes 36 of the grate 35.
