The disclosed embodiments relate generally to management of liquids in residential or commercial kitchens or workshops.
Kitchens often contain pots of hot or boiling liquid for preparing food. Such pots are also used for industrial production or processing. Such pots of hot liquid may pose a scald hazard (e.g., boiling water) or burn hazard (e.g., frying oil). A pot containing liquid may also pose a weight hazard. Even if the liquid is cold the pot may be heavy enough to cause injury to a person lifting it (e.g., back strain, or risk of dropping the pot) or losing balance and falling.
Conventional methods of emptying pots often require a user to lift the full pot of liquid (heavy and usually hot or boiling) to a sink or waste disposal area, and pour the pot down. Alternative methods involve scooping liquid out step by step to reduce the volume/weight of the pot contents prior to lifting the pot. This also is risky as it poses a splash and/or steam scald hazard. Further for liquids that may be flammable (e.g., frying oil) one must take care to avoid the liquid spilling onto the cooking/heating surface as it poses a fire and/or fume hazard (from oil fuming, smoking, or igniting under heat).
It would be desirable to have a method and system to empty pots or other containers of liquid so that the liquid may be safely, cleanly, and rapidly removed from the pot. It would be desirable to allow this removal to be controlled by the user or controlled automatically by the system.
A liquid disposal system, comprises a nozzle configured to suck liquid from a kitchen container, wherein the nozzle is configured to be manipulated by a user's hand, a pipe coupled to the nozzle, wherein the pipe is configured to direct the liquid from the nozzle to a disposal means, and a suction pump coupled to the nozzle and to the pipe, wherein the suction pump is configured to suck the liquid through the nozzle and the pipe when the suction pump is activated.
In some embodiments, the suction pump is electrically operated and configured to be activated by the user's hand. In some embodiments, the suction pump comprises a self-priming pump. In some embodiments, the nozzle is configured to be coupled to a filter for preventing particles from clogging the nozzle, pipe, or pump.
In some embodiments, the system comprises a back-flow preventer for preventing previously sucked liquid or particles from flowing back out the nozzle. In some embodiments, the operation of the suction pump is configured to be controlled by the user's hand manipulating the nozzle. In some embodiments, the operation of the suction pump is configured to be activated automatically by a liquid sensor in the nozzle. In some embodiments, the liquid sensor is configured to activate the pump when placed in a liquid, and to deactivate the pump when removed from the liquid or when the liquid runs dry or runs below a shut-off level. In some embodiments, the suction pump and the nozzle are housed in a handheld unit configured to be manipulated by the user's hand. In some embodiments, the handheld unit further comprises a grinder for reducing the size of a solid particle entering the nozzle.
In some embodiments, disposal means comprises a waste water drain. In some embodiments the disposal means comprises a kitchen garbage disposal unit. In some embodiments, the suction pump is configured to be electrically coupled to the kitchen garbage disposal. In some embodiments, the disposal means comprises a settling tank for separating liquid from solid waste.
In some embodiments, a mount for securing the nozzle is proximate to a cooktop. In some embodiments, the mount comprises a lifting mechanism coupled to the nozzle for lifting the nozzle to an elevated level above the cooktop or allowing the nozzle to be lowered to the cooktop. In some embodiments, the mount comprises a swinging mechanism coupled to the nozzle for positioning the nozzle in a first position above the cooktop and allowing the nozzle to be lowered to the cooktop, or in a second position away from the cooktop. In some embodiments, the mount comprises a holder for securing the nozzle substantially level with the cooktop.
A handheld liquid disposal unit comprises a nozzle configured to suck liquid from a kitchen container, a pipe coupling for attaching an exit pipe to the handheld liquid disposal unit, wherein the pipe coupling is configured to direct liquid from the handheld liquid disposal unit to an exit pipe, and a suction pump coupled to the nozzle and to the pipe coupling, wherein the suction pump is configured to suck liquid through the nozzle and direct the liquid to the pipe coupling when the suction pump is activated.
In some embodiments the suction pump is configured to be powered by an electrical supply. In some embodiments, the suction pump is configured to be powered by a rechargeable battery coupled to the unit. In some embodiments, the rechargeable battery is configured to be removable from the unit and to be charged separately from the unit. the rechargeable battery is configured to be charged while coupled to the unit by direct or indirect electrical contact.
A handheld liquid disposal unit comprises a nozzle configured to suck liquid from a kitchen container, and a pipe coupling for attaching an exit pipe to the handheld liquid disposal unit, wherein the pipe coupling is configured to direct liquid from the handheld liquid disposal unit to an exit pipe, wherein the nozzle and pipe are configured to be coupled to a suction pump external to the unit to suck liquid through the nozzle and direct the liquid to the pipe coupling when the suction pump is activated.
In some embodiments, the handheld liquid disposal unit comprises a switch configured to send an activation signal to the suction pump or to a controller coupled to the suction pump, in response to a user's input or in response to a sensor instruction. In some embodiments, the activation signal is transmitted wirelessly from the unit to the suction pump or to the controller coupled to the suction pump. In some embodiments, the activation signal is transmitted over a physical connection from the unit to the suction pump or to the controller coupled to the suction pump.
Like reference numerals refer to corresponding parts throughout the drawings.
In some embodiments, when a user activates the suction vent and places it in the pot of liquid, the suction vent removes the liquid from the pot in a controlled fashion.
In some embodiments, the suction function (e.g., a suction pump) is electrically operated and configured to be activated by a user's hand. For example, the suction pump may draw power from an external source or from an internal rechargeable battery, and may be activated by a control (e.g., button, lever, or capacitive sensor) on the nozzle. In some embodiments, the suction pump comprises a self-priming pump.
In the embodiments of
In some embodiments, the operation of the suction pump is configured to be controlled by the user's hand manipulating the nozzle. For example, a user may manually turn on the pump with same hand that holds the nozzle. In some embodiments, one-handed operation is a preferred embodiment of the system.
In some embodiments, the operation of the suction pump is 310 configured to be activated automatically by a liquid sensor in the nozzle 120. For example, the pump may turn on when it senses or is immersed in liquid. In some embodiments, the liquid sensor is configured to activate the pump when placed in a liquid, and to deactivate the pump when removed from the liquid, or when the liquid runs dry or runs below a shut-off level. For example, the pump may have an automatic shut-off function to prevent damage to the pot or pump if most or all liquid removed.
In the example of
In another embodiment illustrated 350 in
In an embodiment 501 (
In some embodiments, the nozzle 120 comprises a grinder for reducing the size of a solid particle entering the nozzle. For example, a small rotating blade may be coupled to the nozzle or handheld unit, to prevent large food particles from clogging the nozzle or pump. For example hand-held food blender blade or the likes may be used.
In some embodiments, the nozzle 120 may comprise a back-flow preventer to prevent previously sucked liquid or particles from flowing back out the nozzle. In some applications it is desirable to prevent waste that has been sucked up from flowing back down and contaminating the pot 105. This is particularly relevant in kitchen or food preparation applications. In some embodiments, the nozzle 120 may contain an anti-siphon valve.
Mount 710 is configured to direct hose 725 (or another hose or pipe to which hose 725 is coupled) to a pump 310 and/or to a drain 320. In embodiments where a pump is included in the handheld unit (of which nozzle 120 is part) then pump 310 may not be necessary.
An advantage of this arrangement is that it allows a user to easily grasp the nozzle and direct it to the pot, activate the suction function to drain liquid from the pot, and then release the nozzle so it that it raises up above the cooktop out of the way. In some embodiments, the spring 820 may be locked in an extended position so a user can place the nozzle 120 in the pot 105 to drain the liquid 115, and step away for a short period while the draining is occurring. This avoids the need for the user to stand at the pot holding the nozzle in the pot during the draining process. Alternatively, the nozzle 120 may have a clip to attach to the pot or to a handle of the pot to keep the nozzle in place in the pot during the suction operation.
This arrangement provides a swinging mechanism (e.g., via connection 730 and/or 735) coupled to the nozzle for positioning the nozzle in a first position above the cooktop and allowing the nozzle to be lowered (e.g., via connection 730 and/or 735) to the pot 105 on the cooktop, or in a second position away from the cooktop. The swinging mechanism allows the nozzle to be swung back towards or against a wall, or swung out over the cooktop so the nozzle can be lowered into a kitchen container 105. This provides a convenient means for positioning the nozzle, draining liquid, and storing the nozzle out of the way, via a one-handed operation.
An advantage of this arrangement is that the nozzle is stored out of the way so no liquid or drips can fall out into the pot or on the range. A further advantage is that the excess or unused hose is stored in a visually pleasing manner out of sight, and there is nothing store above or to the side of the range/cooktop, providing a sleeker and less cluttered arrangement.
In some embodiments of the described system, the suction pump and the nozzle are housed in a handheld unit configured to be manipulated by the user's hand. In this arrangement, the nozzle and pump are in single unit/chassis for one-handed operation, like a one-handed food blender.
A suction pump 1215 housed within the nozzle (HLDU) is coupled to the opening 1221 and to the pipe coupling 1235, wherein the suction pump is configured to suck liquid through the opening and direct the liquid to the pipe coupling when the suction pump is activated.
A battery 1210 (in some embodiments, rechargeable) is housed within the nozzle (HLDU) is coupled to the pump 1215 and to a switch 1210. Upon a user activating the switch 1210 (or upon automatic activation), the battery provides power to the pump 1215 and liquid is sucked up through opening 1221 and expelled through pipe coupling 1235.
In some embodiments, the suction pump is configured to be powered by an electrical supply. In some embodiments, the suction pump is configured to be powered by a rechargeable battery coupled to the nozzle. In some embodiments, the suction pump is configured to be activated by a user input (e.g., a switch, lever, button, etc.) or through electrical means (optical sensor, capacitive sensor, heat sensor, etc.) or through an automatic means (liquid sensor, proximity sensor, heat sensor, or other sensor or computer means).
In some embodiments, the rechargeable battery 1210 is configured to be removable from the unit and to be charged separately from the unit. This separate charging may operate like a garage power tool that has a removable and chargeable battery.
In some embodiments, the rechargeable battery is configured to be charged while coupled to the unit by direct or indirect electrical contact. For example, a direct connection for charging may be provided through regular conductive contacts. Alternatively, an indirect connection for charging may be provided by inductive charging. An advantage of inductive charging is that there are no exposed electrical contacts to get wet and short or corrode. In some embodiments, the battery may be recharged when the nozzle (HLDU) is stored, such as in a mount/holder as previously described. For safety reasons, it may be desirable to electrically isolate the charging power supply from the nozzle when the nozzle is in use (e.g., used next to liquid).
In an embodiment, a handheld liquid disposal unit (HLDU) provides a self-contained nozzle and pipe coupling, configured to couple to a suction system. The HLDU comprises a nozzle configured to suck liquid from a kitchen container, and a pipe coupling for attaching an exit pipe to the handheld liquid disposal unit. The pipe coupling is configured to direct liquid from the handheld liquid disposal unit to an exit pipe, in response to a suction force. The nozzle and pipe are configured to be coupled to a suction pump external to the unit to suck liquid through the nozzle and direct the liquid to the pipe coupling when the suction pump is activated.
In some embodiments, the HLDU furthers comprising a switch or sensor means (as described) configured to send an activation signal to the suction pump or to a controller coupled to the suction pump, in response to a user's input or in response to a sensor instruction. For example, a switch on the handheld unit when activated by a user or automatically activated sends a command to the suction pump or controller to turn the suction pump on or off.
In some embodiments, the activation signal is transmitted wirelessly from the HLDU to the suction pump or to the controller coupled to the suction pump. For example, such wireless transmission may include a Bluetooth network or a short range wireless network connection, including a wireless Personal Area Network, a wireless Home Automation Network, or other wireless control means.
In some embodiments, the activation signal is transmitted over a physical connection from the HLDU to the suction pump or to the controller coupled to the suction pump. For example, a low-voltage wire circuit may be used. In embodiments where it is desirable to avoid sending electricity in parallel with a water line (e.g., due to building code or industrial safety, electrical, or fire codes, ordinances or best practices), an optical connection may be used (e.g., a fiber optic type cable) to convey an activation signal to the pump or controller. In some embodiments a high frequency audio signal (e.g., a signal above the range of human and/or domestic animal hearing) could be used.
In some embodiments, the liquid disposal system can be constructed from one or more components which allow for a sanitary system for the transport of fluids. Such components are resistant to soaps, solvents, chemicals or agents utilized in the removal and cleaning of particulate matter, pathogens (bacteria, viruses, fungus, mold and algae) and biofilm from surfaces capable of cross contamination. In alternate embodiments, in portions of the liquid disposal system where the temperature does not exceed 170 degrees Fahrenheit, antimicrobial coatings can be utilized. In further embodiments, tubing capable of higher temperatures such as polysulfone can be used. In other embodiments, the liquid disposal system may comprise one or more materials including stainless steel, copper, neoprene, carbon composites or professional grade plastics, polymers and ceramics. In some embodiments, combinations of one or more of these materials may be used on interior and/or exterior surfaces of the liquid disposal system.
Each of the systems and components described herein may be represented as electronic designs or code for manufacturing via computer-aided design/manufacture (CAD/CAM) or computer numerical controlled (CNC) systems. These designs or code may be stored in one or more memory devices, and correspond to a set of instructions for performing a function or manufacturing a component described above.
Such memory devices may include high-speed random access memory, such as DRAM, SRAM, DDR RAM or other random access solid state memory devices; and may include non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid state storage devices. Memory devices may optionally include one or more storage devices remotely located from manufacturing machines or systems described. Memory devices may include computer cloud storage and data attached to email systems.
While the foregoing has been described in the context if kitchens and food preparation, it is applicable to other environments also. The described embodiments may also be used in kitchen cleanup and/or food disposal environments (for example, a home, restaurant, or institution (prison, hospital, school, office, etc.)
In a further example, the embodiments may be adapted for use with hazardous liquids or materials. For example, in some environments liquids may require disposal that are corrosive, acidic, basic, poisonous, radioactive, toxic, or otherwise hazardous. The described embodiments may be adapted for use in safe disposal of such liquids.
