The present invention relates generally to food waste disposers and more particularly to batch feed food waste disposer interlock devices.
A food waste disposer, sometimes called a garbage disposal unit, is typically electrically powered and installed under a kitchen sink between the sink's drain and trap. Food fed into the food waste disposer is shredded into small pieces, often less than a few millimeters in size. The shredded food waste is then passed through a home's plumbing system for downstream disposal into existing infrastructure, such as, for example, sewage systems and wastewater treatment plants.
A typical food waste disposer has a high starting torque electric motor, which drives a turntable inside a grinding chamber into which food waste drops. Swiveling metal impellers near a top edge of the turntable throw the food waste against a grinding ring repeatedly, until the food waste is small enough to pass through an opening in a ring, allowing the food waste to be flushed down the sink drain.
The food waste disposer was invented by John W. Hammes, a Racine, Wis. architect, in 1927, who applied for a patent in 1933 that was issued in 1935 as U.S. Pat. No. 2,012,680 (Hammes). Mr. Hammes put his invention into practice in 1940, when he started to market the invention. Hammes' claim, however, was disputed by General Electric, which introduced a food waste disposer in 1935. Fifty percent of homes in the United States had food waste disposers by 2009.
Continuous feed and batch feed food waste disposers are the prevalent types of food waste disposers in use, today.
Although continuous feed units are more common than batch feed units, batch feed units are considered safer.
Continuous feed units are operated by feeding food waste into the waste disposer after starting the food waste disposer and are more common than batch feed units.
Batch feed food waste disposers are considered safer than continuous feed units, because the top of the batch feed food waste disposer is covered during operation, preventing foreign objects from falling into the unit and preventing children's or adult's hands from getting mangled during the disposal process. Typical batch feed units are operated by placing food waste inside the waste disposer and placing a specially designed cover over the opening, before starting the unit. Some batch feed food waste disposer covers manipulate mechanical switches, while others have magnets in the covers that align with magnets in the units. Slits in the covers allow water to flow through the units.
A batch feed food waste disposer interlock device that is capable of being removably and matingly used with a variety of different food waste disposers having magnetically activated switches, that is capable of activating the magnetically activated switches for turning the food waste disposer on and off, has a removable basket strainer that may be used to discard any collected debris therefrom is necessary.
The batch feed food waste disposer interlock device should be capable of being used as a retrofit in existing installations or in new installations.
The batch feed food waste disposer interlock device should be capable of switching the food waste disposer that the interlock device is removably and matingly removably seated in on and off, as required, acting as a basket strainer, catching and collecting debris, controlling the flow of water, fluid, food waste, or wastewater, by either allowing or preventing the water or food waste from entering and flowing through the interlock device and into the food waste disposer, as directed by a user.
The batch feed food waste disposer interlock device should be capable of turning the food waste disposer on when the food waste disposer interlock device is removably seated in the sink flange of the sink and is in a food waste disposer activation position and turning the food waste disposer off when the food waste disposer interlock device is in the sink flange of the sink and is in a position other than the food waste disposer activation position.
The batch feed food waste disposer interlock device should be capable of being easily and conveniently removed from the food waste disposer to clean and remove any remaining debris therefrom and turning the food waste disposer off, when the food waste interlock device is removed from the sink flange of the sink.
The batch feed food waste disposer interlock device should be durable, light weight, inexpensive, safe to use, attractive, sturdy, of simple construction, and capable of being used in a quick, convenient, and efficient manner.
Different batch feed food waste disposer interlock devices have heretofore been known. However, none of the batch feed food waste disposer interlock devices adequately satisfies these aforementioned needs.
Different strainers and drain devices have heretofore been known. However, none of the strainers and drain devices adequately satisfies these aforementioned needs.
For the foregoing reasons, there is thus a need for a batch feed food waste disposer interlock device that is capable of being removably and matingly used with a variety of different food waste disposers having magnetically activated switches, that is capable of activating the magnetically activated switches for turning the food waste disposer on and off, has a removable basket strainer that may be used to discard any collected debris therefrom is necessary.

The batch feed food waste disposer interlock device should be capable of turning the food waste disposer on when the food waste disposer interlock device is removably seated in the sink flange of the sink and is in a food waste disposer activation position and turning the food waste disposer off when the food waste disposer interlock device is in the sink flange of the sink and is in a position other than the food waste disposer activation position.
The batch feed food waste disposer interlock device should be capable of being easily and conveniently removed from the food waste disposer to clean and remove any remaining debris therefrom and turning the food waste disposer off, when the food waste interlock device is removed from the sink flange of the sink.
The batch feed food waste disposer interlock device should be durable, light weight, inexpensive, safe to use, attractive, sturdy, of simple construction, and capable of being used in a quick, convenient, and efficient manner.

These and other features, aspects, and advantages of the present invention will become better understood with regard to the following description, appended claims, and accompanying drawings where:
The preferred embodiments of the present invention will be described with reference to
The food waste disposer 18 is typically fastened to a sink 20 with a food waste disposer sink mount 22, which has a flange 24, which may be used to removably and matingly receive and seat the interlock device 12 therein. The food waste disposer sink mount 22 is often a three hole mount for passing bolts 26 therethrough and fastening the food waste disposer 18 to the sink 20, although other suitable fastening arrangements may be used.
In more detail, an upper clamp ring 25 fits around the circumference of the flange 24 underneath the sink 20 and clamps the flange 24 securely to the sink 20 using three of the bolts 26. The bolts 26 are removably threaded through a lower mounting ring 27, which securely mounts the food waste disposer 18 beneath the flange 24. The lower mounting ring 27 is fastened to the flange 24 by a snap ring 29.
The magnetically activated switch 14 is fastened to the food waste disposer sink mount 22 adjacent the flange 24, using two of the bolts 26, although other suitable fastening arrangements may be used.
The electric circuit box 16, which is connected to an external power source, supplies electrical power to the magnetically activated switch 14. The food waste disposer 18 is activated and electrical power is supplied to the food waste disposer 18 by the magnetically activated switch 14, when the magnetically activated switch 14 is activated by the interlock device 12.
The interlock device 12 must be seated in the flange 24 and the interlock device 12 must be in a food waste disposer activation position for the food waste disposer 18 to be activated.
If the interlock device 12 is not seated in the flange 24 or if the interlock device is withdrawn from the flange 24, the food waste disposer 18 will not be activated. Likewise, the food waste disposer 18 will turn off, if the food waste disposer 18 is already turned on and the interlock device 12 ceases to be seated in the flange 24 or if the interlock device is withdrawn from the flange 24.
If the interlock device 12 is seated in the flange 24 and if the interlock device 12 is in a food waste disposer activation position, the food waste disposer 18 will be activated and electric power will be supplied to the food waste disposer by the electric circuit box 16.
The interlock assembly 10 may be used to retrofit an existing food waste disposer 18 and convert a continuous feed food waste disposer into a batch feed food waste disposer. Alternatively, the interlock assembly 10 may be used in a new batch feed waste disposer installation. The interlock assembly 10 may optionally be a kit.
The magnetically activated switch 14 has a magnetically activated switch magnet 28 seated in a magnetically activated switch magnet housing 30 that is pivotally connected to magnetically activated switch housing 32. The magnetically activated switch 14 has a first linkage 34 that is pivotally coupled to the magnetically activated switch magnet housing 30 and a second linkage 36 that is pivotally coupled to the first linkage 34. The second linkage 36 is also pivotally connected to the magnetically activated switch housing 32.
The second linkage 36 has a lever arm 38, which presses against spring loaded switch activator button 40 of spring activated switch 42 and activates the food waste disposer 18 by supplying electric power to the food waste disposer 18, when the magnetically activated switch magnet 28 is drawn to one of the interlock device magnets 44 of the interlock device 12.
The magnetically activated switch magnet 28 is drawn to one of the interlock device magnets 44, when the interlock device 12 is seated in the flange 24 and one of the interlock device magnets 44 is adjacent the magnetically activated switch magnet 28.
When the interlock device 12 is seated in the flange 24 and the interlock device 12 is in a food waste disposer activation position, the magnetically activated switch magnet 28 is adjacent one of the interlock device magnets 44 of the interlock device 12, and the magnetically activated switch magnet 28 is drawn to one of the interlock device magnets 44, which activates the food waste disposer 18.
Alternatively, when the interlock device 12 is not in a food waste disposer activation position, the magnetically activated switch magnet 28 is not adjacent one of the interlock device magnets 44 of the interlock device 12, and the spring activated switch 42 is switched off. When the spring activated switch 42 is switched off, the food waste disposer 18 is not activated or is deactivated if already turned on.
A mounting spring 31 is used to hold the magnetically activated switch housing 32 in place at one of the bolts 26.
The interlock device 12 may be removably, matingly, and rotatably seated in and unseated from the flange 24. The interlock device 12 may, thus, be removed from the flange 24, in order to remove, for example, any collected debris from the interlock device 12, after which, the interlock device 12 can be reseated in the flange 24.
The interlock device 12 is substantially disk shaped and has a substantially disk shaped base 48 having:
The opposing interlock device magnets 44 are preferably arcuate shaped or C-shaped and are preferably embedded in the upper cylindrical outer collar 50 of the substantially disk shaped base 48 of the interlock device 12, although other suitable shaped magnets and locations adjacent the periphery of the upper cylindrical outer collar 50 or adjacent the periphery of the disk shaped base 48 may be used.
The second linkage 36 has the lever arm 38, which presses against the spring loaded switch activator button 40 of the spring activated switch 42 and activates the food waste disposer 18 by supplying electric power to the food waste disposer 18, when the magnetically activated switch magnet 28 is drawn to one of the opposing interlock device magnets 44 of the interlock device 12.
The magnetically activated switch magnet 28 is drawn to one of the opposing interlock device magnets 44, when the interlock device 12 is seated in the flange 24 and one of the interlock device magnets 44 is adjacent the magnetically activated switch magnet 28.
When the interlock device 12 is seated in the flange 24 and the interlock device 12 is in a food waste disposer activation position, the magnetically activated switch magnet 28 is adjacent one of the opposing interlock device magnets 44 of the interlock device 12, and the magnetically activated switch magnet 28 is drawn to one of the opposing interlock device magnets 44, which activates the food waste disposer 18.
Alternatively, when the interlock device 12 is not in a food waste disposer activation position, the magnetically activated switch magnet 28 is not adjacent one of the opposing interlock device magnets 44 of the interlock device 12, and the spring activated switch 42 is switched off. When the spring activated switch 42 is switched off, the food waste disposer 18 is not activated or is deactivated if already turned on.
The food waste disposer sink mount 22 is often a three hole mount for passing the bolts 26 therethrough and fastening the food waste disposer 18 to the sink 20, although other suitable fastening arrangements may be used.
The magnetically activated switch 14 is fastened to the food waste disposer sink mount 22 adjacent the flange 24, using two of the bolts 26 that are used to fasten the food waste disposer 18 to the sink 20, using the food waste disposer sink mount 22.
The interlock device 100 may be used with or as a component of the interlock assembly 10 or may be used with or as a component of any other suitable interlock assembly.
The interlock assembly 126 is substantially the same as the interlock assembly 10, except that the interlock assembly 126 has a bottom mounted splash guard 128 mounted to food waste disposer sink mount 130. The food waste disposer sink mount 130 has an extended or deeper sink flange 131 to make room for and facilitate mounting the bottom mounted splash guard 128 to the sink flange 131 beneath the interlock device 100.
The bottom mounted splash guard 128 is preferably of a resilient and flexible material, such as, for example, rubber or other suitable waterproof material, which has soundproofing or sound attenuation properties, and is mounted to the bottom of the food waste disposer sink mount 130 for additional sound attenuation and for aesthetic purposes.
The bottom mounted splash guard 128 has an inverted dome 132 and X shaped expandable and retractable opposing splash guard fins 133, which define quadrants 134 of the inverted dome 132, each of which have at least one discharge hole 135. Each of the X shaped expandable and retractable opposing splash guard fins 133 have lengthwise discharge openings 136 to facilitate discharge of water, fluid, food waste, or wastewater therethrough from the bottom of the bottom mounted splash guard 128.
The substantially disk shaped base 118 has interior wall 137, substantially centrally disposed base hub 138, which has the opposing longitudinal helical ramps 114 or helical cams, and a plurality of spokes 139 therebetween, which define a plurality of base drain holes 140 therebetween. The substantially disk shaped base 118 may have alternative base drain holes or other suitable base drain holes.
The alternate embodiment of the interlock assembly 126 is preferably used with magnetically activated switch 141 or other suitable magnetically activated switch fastened to the food waste disposer sink mount 130, as shown in
Although, the interlock device 100 functions substantially the same as the interlock device 12, the interlock device 100 has the ergonomic S-shaped handle 102 in the shape of a long S for improved usability and user friendliness, and improvements in construction, durability, reliability, and manufacturing, and encourage a user to twist the ergonomic S-shaped handle 102 clockwise and raise upper strainer basket 143 prior to turning a food waste disposer on for use, such as the food waste disposer 18 or other suitable food waste disposer.
The ergonomic S-shaped handle 102 may alternatively have the shape of the integral symbol, the shape of a florin sign, or the modified shape of Latin script for the letter f. The ergonomic S-shaped handle 102, the florin shaped handle, or the modified Latin script letter f shaped handle, encourages a user to twist the ergonomic S-shaped handle 102 clockwise and raise the upper strainer basket 143, prior to turning the power to the food waste disposer 18 or other suitable waste disposer on.
The substantially disk shaped stepped spindle mounted seal 104, which is shown in
The substantially centrally disposed seal hub 106 has a substantially centrally disposed bore 144 therethrough, and the lower substantially centrally disposed spindle 110 is rotatably mounted through the substantially centrally disposed bore 144. The lower spindle retaining collar 116 is integral with the substantially centrally disposed spindle 110. The lower spindle retaining collar 116 is larger than the diameter of the substantially centrally disposed bore 144 to ensure that the substantially centrally disposed spindle 110 does not come apart from the substantially disk shaped base 118. Additionally, the lower substantially centrally disposed spindle 110 has a larger diameter than that of the lower substantially centrally disposed spindle 74 of the interlock device 12, for added strength and durability.
The opposing longitudinal helical ramps 114 or helical cams have helical cam profiles, which have helical cam surfaces. The lower substantially centrally disposed spindle 110 has the opposing longitudinal fins 112, which travel along the opposing longitudinal helical ramps 114 or helical cams, which have the helical cam surfaces, when the ergonomic S-shaped handle 102 is rotatably twisted.
The substantially disk shaped base 118 has the opposing longitudinal helical ramps 114 or helical cams, which are best shown in
The interlock device 100 is typically used in an open configuration or a closed configuration, as shown in
The interlock device 100 is open and allows fluid, water, or wastewater to flow through the interlock device 100, when the opposing longitudinal fins 112, which travel along the opposing longitudinal helical ramps 114 or helical cams, when the ergonomic S-shaped handle 102 is rotatably twisted clockwise to raise the upper strainer basket 143 to an open configuration, as shown in
The interlock device 100 is closed and prevents fluid, water, or wastewater from flowing through the interlock device 100, when the opposing longitudinal fins 112, which travel along the opposing longitudinal helical ramps 114 or helical cams, when the ergonomic S-shaped handle 102 is rotatably twisted counterclockwise to lower the upper strainer basket 143 to a closed configuration, as shown in
The opposing food waste disposer activation magnets 122 are used to activate a food waste disposer, such as the food waste disposer 18 or other suitable waste disposer, when the opposing food waste disposer activation magnets 122 are coupled to the food waste disposer, such as the food waste disposer 18 or other suitable waste disposer.
The substantially disk shaped base 118 has the opposing containers 120, which hold the opposing food waste disposer activation magnets 122 therein. The opposing containers 120 have nubs 150 and 152, which aid in holding the opposing food waste disposer activation magnets 122 in position within the opposing containers 120 and create a tight fit for the opposing food waste disposer activation magnets 122 within the opposing containers 120. The opposing containers 120 also have the opposing container covers 124, which cover the opposing containers 120 and hold the opposing food waste disposer activation magnets 122 therein. The interlock device 100 has a flange seal 154 about the substantially disk shaped base 118, which creates a seal between the interlock device 100 and the extended or deeper sink flange 131.
