The present disclosure relates to a device for drying and/or polishing items such as glasses and cutlery.
Drying and polishing cutlery and glasses is one of the core roles and responsibilities for those in the hospitality industry. The need for drying and polishing is created due to the streaks and spots that are frequently left on the glasses and cutlery after cleaning, particularly when the glasses and cutlery are cleaned using a dishwasher. Due to a lack of an effective commercial solution, the required drying and polishing of cutlery is commonly performed manually with a rag. Each item is held by hand, and while holding the item, is dried by wiping the item with the rag. This traditional method for drying and polishing cutlery and glasses is time consuming and also creates potential hygiene issues due in part to frequent reuse of the drying rag.
Devices for drying and polishing items such as glasses and cutlery have previously been proposed but have generally been ineffective. Prior devices are large, complicated devices and are generally inconvenient to use. For example, the device disclosed in EP1532921 can only handle cutlery and not glasses. U.S. Pat. No. 6,907,893 is configured for cleaning bottles within a sealed enclosure and would not be appropriate to use for rapidly drying and polishing glasses and cutlery, neither would U.S. Pat. No. 7,604,012, which also includes means for washing the items.
Furthermore, previous devices have suffered from a lack of the control of steam within the devices. For example, previous devices have not included releasing steam only when the items for drying and/or polishing are inserted into the device.
Even further, previous devices have also suffered because the previous devices are generally bulky devices that can take up a lot of space in kitchens, including considerable space on kitchen countertops which would be better used to prepare food for restaurant customers. Further, the previous devices suffer from the inability to both polish and dry stemware and automatically dry and polish cutlery in a single, compact device.
Examples of the disclosure seek to solve, or at least ameliorate, one or more disadvantages of previous devices for drying and polishing items such as glasses and cutlery, or at least provide a useful alternative.
In one embodiment, a device for drying and polishing a plurality of items including glasses and cutlery is provided. The device includes (i) a plurality of movable cleaning elements configured to at least one of dry and polish the items, the plurality of movable cleaning elements including at least one first movable cleaning element, and at least one second movable cleaning element and (ii) an enclosure defining a chamber, wherein the at least one first movable cleaning element and the at least one second movable cleaning element are located in different positions in the chamber. The enclosure includes (i) a first aperture at a first enclosure location, the first aperture adapted to receive a first item of the plurality of items, wherein the at least one first movable cleaning element is proximate the first aperture to at least one of polish and dry the first item when the first item is inserted into the chamber through the first aperture, (ii) a second aperture at a second enclosure location, the second aperture adapted to enable a second item of the plurality of items to be inserted into the chamber, (iii) a third aperture at a third enclosure location, the third aperture adapted to enable the second item of the plurality of items to exit the chamber, and (iv) a channel assembly located in the chamber proximate the at least one second movable cleaning element, the channel assembly defining a channel path, the channel path extending between the second aperture and the third aperture, wherein the second item of the plurality of items is at least one of polished and dried by the at least one second movable cleaning element as the second item of the plurality of items moves along the channel assembly path between the second and third apertures.
In another embodiment, a device for drying and polishing a plurality of items including glasses and cutlery is provided. The device includes (i) a plurality of movable cleaning elements configured to at least one of dry and polish the items, the plurality of movable cleaning elements including at least one first movable cleaning element, and at least one second movable cleaning element, (ii) an enclosure defining a chamber, wherein the at least one first movable cleaning element and the at least one second movable cleaning element are located in different positions in the chamber, and (iii) a selectively operable steam distribution system configured to apply steam within the chamber to at least one of (a) the at least one of the first and second cleaning elements and (b) the items inserted into at least one of the first and second apertures, wherein the steam distribution system is operable upon insertion of the items into at least one of the first and second apertures. The enclosure includes (i) a first aperture at a first enclosure location, the first aperture adapted to receive a first item of the plurality of items, wherein the at least one first movable cleaning element is proximate the first aperture to at least one of polish and dry the first item when the first item is inserted into the chamber through the first aperture, (ii) a second aperture at a second enclosure location, the second aperture adapted to enable a second item of the plurality of items to be inserted into the chamber, (iii) a third aperture at a third enclosure location, the third aperture adapted to enable the second item of the plurality of items to exit the chamber, and (iv) a channel assembly located in the chamber proximate the at least one second movable cleaning element, the channel assembly defining a channel path, the channel path extending between the second aperture and the third aperture, wherein the second item of the plurality of items is at least one of polished and dried by the at least one second movable cleaning element as the second item of the plurality of items moves along the channel assembly path between the second and third apertures.
Preferred embodiments of the disclosure will be further described, by way of non-limiting examples only, with reference to the accompanying drawings in which:
With reference to
The device includes an enclosure 12 having apertures 14a, 14b through which an end of the items can be inserted, a plurality of movable cleaning elements 16 within the enclosure 12 for drying and/or polishing the items, and a selectively operable steam distribution system 34 (to be described further below) for applying steam within the enclosure 12 to at least one of the cleaning elements 16 and/or the items, whereby the cleaning elements 16 dry and/or polish the items. When the items are selectively inserted into either aperture 14a or 14b, the user holds the item adjacent the associated cleaning elements while the item is being polished and dried. The device user then removes the polished and dried items through the aperture.
The enclosure 12 is fitted with an operation switch 18 and a display screen 20, which may be in the form of a LCD screen. The enclosure 12 also includes a lid 22, openable, as illustrated in
The electric drives 24 rotate pulleys 26 which, via belts 28, causes rotation of the shafts on which the cleaning elements 16 are mounted. Idlers 30 may be provided for guiding/directing the belt. Preferably, some of the cleaning elements 16 within the first and second sets are configured for counter rotation to improve drying/polishing of the glasses/cutlery. To achieve this, gears may be used to couple cleaning elements or other components within the rotating elements and transfer rotational direction as required.
It will be appreciated that not all of the cleaning elements 16 need be directly rotated by belts 28 and that some of the cleaning elements, such as cleaning elements 16f, 16g illustrated, may instead be coupled to a driven cleaning element by gears to enable rotation and to transfer the direction of rotational motion from one cleaning element to the next.
A pump 42 is provided for distributing the steam. Control valves 44a, 44b are also provided to control distribution of steam between cleaning elements configured for use with cutlery and cleaning elements for use with glasses.
For safety, a pressure reducer 46 is provided on a mains water intake, with one-way valves 48 used to control flow of water from the reservoir 36 (or water intake) and to the pressure reducer 46. Also, a flow limiter may be provided to limit the amount of steam that can be applied within the enclosure 12.
The steam distribution system 34 is operable on detection of an end of said items being inserted into the enclosure 12. In some embodiments, sensors may be used to detect an end of said items being inserted into the enclosure 12. In the illustrated embodiment, the steam distribution system 34 is operable upon an end of one of said items being brought into contact with at least one cleaning element 16. In this regard, the steam distribution system 34 is operable on applying pressure to at least one of the cleaning elements 16 via applying pressure to the item once inserted within the enclosure 12, for example by pressing an upturned glass downwardly onto a cleaning element.
Within the cleaning elements for use with glasses, only some of the rotating elements may be configured as “switchable”, i.e. configured so that by applying pressure thereto causes activation of the steam distribution system 34. In the illustrated example, only internal cleaning element 16a, which is configured for cleaning the inside of a glass, and external cleaning element 16c, which is configured for cleaning an external area of the glass are so configured, with cleaning elements 16b, 16d, 16e being provided without a switch. Exerting pressure on either cleaning element 16a or 16c will result in steam being applied to all of the cleaning elements in the first set, i.e. 16a, 16b, 16c, 16d and 16e, resulting in both external and internal cleaning of the glass.
With “unswitched” cleaning elements 16b, 16d, 16e steam can still be applied to those cleaning elements, though the steam is only applied on operation of the switches associated with cleaning elements 16a, 16c. Such an arrangement can reduce manufacturing costs and complexity without adversely affecting performance.
At the top of the steam pipe 54 is a nozzle 58 that directs steam onto a conical diffuser 60, which rotates with the cleaning head 50, for directing steam radially outwardly along path A from the steam pipe 54 via apertures 62 formed in shaft 52. Steam flows through apertures 62 and into cleaning head 50 to facilitate drying and polishing of the glass. The apertures are preferably two apertures offset 180 degrees around the shaft, i.e. on opposite sides of the shaft, though they may also be otherwise configured with a single aperture or more than two apertures. Although a single set of apertures is provided at a mid point of the cleaning element, it will be appreciated that they may be offset from the mid point, and that more that one set of apertures may be provided.
On activation of the steam distribution system 34, steam flows from the boiler 38, via the conduit 40, into steam pipe 54 and upwardly along path B, as illustrated in
Again, at the top of the steam pipe 54 is a nozzle 58 that directs steam onto a conical diffuser 60, which rotates with the cleaning head 50, for directing steam radially outwardly along path A from the steam pipe 54 via apertures 62 formed in the steam pipe 54. Steam flows through apertures 62 and into cleaning head 50 to facilitate drying and polishing of the glass. Although a single set of apertures is provided at a mid point of the cleaning element, it will be appreciated that they may be offset from the mid point, and that more that one set of apertures may be provided.
With switched cleaning elements 16a, 16c, the steam distribution system 34 is operable by applying pressure to the cleaning element 16a via the cleaning head 50 axially along the axis of rotation of the cleaning element 16a to trigger steam flow to all of the cleaning elements in the first set, i.e. 16a, 16b, 16c, 16d, 16e.
A spring 70 is provided to resiliently bias the base plate 64 and thus the shaft 52 and cleaning head 50 upwardly, though allow it to be movable downwardly to operate the steam distribution system. A bolt 72 is provided for guiding movement of the brush.
Cleaning elements 16f, 16g, which are configured to dry and polish cutlery, may be unswitched cleaning elements and configured in accordance with cleaning elements 16b, 16d, 16e, as described above. Operation of the steam distribution system 34 for flow of steam to cleaning elements 16f, 16g via control valve 44a may be via a further sensor within the enclosure, such as a proximity sensor to detect the insertion of cutlery, to provide autonomous activation of steam once a piece of cutlery is inserted through the aperture and held in place by the user to hygienically clean/polish the piece of cutlery prior to use. Alternatively, an external switch on or remote from the device 10 may be provided.
The device 10 also includes a programmable microprocessor that can control operation, monitor performance parameters, and log usage data. In one example, the microprocessor can record usage history and provide alerts for replacement of the cleaning elements 16 once a predetermined number of cycles have passed. In other examples, the microprocessor may accept signals from sensors fitted to the device, such as vibration sensors to alert to damage of cleaning elements, which could shut down or limit operation of the device, or moisture sensors to alert to excessive use of steam, which could trigger operation of a heater provided within the enclosure for drying the cleaning elements.
With reference to
Device 100 is substantially similar to device 10. That is, device 100 includes substantially the same components (e.g., cleaning elements 16, rotating assembly 32, a steam distribution system 34, etc.) as device 10 and performs in substantially the same way as device 10 (e.g., by using the steam distribution system and cleaning elements to dry and/or polish the items). Accordingly, like components of device 10, that are included in the description of device 100, will be identified by the the same reference numerals as used in the description of device 10. However, device 100 includes additional features of an integrated device for drying and/or polishing glasses and cutlery in a single device and where the cutlery is cleaned with minimal contact by the user, as is further described herein.
Device 100 includes an enclosure 102 (e.g., substantially similar to enclosure 12 of device 10) that defines a chamber 103 (shown in
A channel assembly 114 extends internally (e.g., in the chamber 103) through the device 100 from the second aperture 112 of the top portion 104 to the third aperture 122 formed in side portion 106a. The channel assembly 114 is configured to guide the items inserted into the second aperture 112 through the enclosure 102 and the chamber 103, as described further herein.
Device 100 further includes the operation switch 18, the display screen 20, and a first button 116 and a second button 118 associated with the display screen 20. In the exemplary embodiment, the buttons 116, 118 may be used to navigate and/or view the display screen 20. In other embodiments, the display screen 20 may be a conventional touchscreen device/graphical user interface, and the buttons 116, 118 may not be included in device 100.
Device 100 is configured to be relatively compact and lightweight such that device 100 has a small footprint and does not take up a large amount of space on the surface (e.g., a countertop of a kitchen) upon which device 100 is placed and is able to be moved by a user without substantial effort or moving equipment. Since counter space may be limited in kitchens and/or bars, especially commercial kitchens and bars, the compact and lightweight device 100 is preferable to large and heavy machinery that polishes and/or dries items. For example, device 100 may be put on a countertop when device 100 is being used and then easily stored away when device 100 is not in use to clear the countertop. Accordingly, device 100 may be preferable to other polishing and drying devices that are permanent or semi-permanent fixtures of kitchens and bars due to the size and weight of the other polishing and drying devices. Further, device 100 provides polishing and drying for both stemware/glasses and cutlery in the single enclosure 102 of device 100, and separate devices are not needed for stemware and cutlery polishing and drying. That is, a user of the device can polish and/or dry a stemware item (e.g., by holding the stemware item proximate to the first aperture 110) while the user is simultaneously placing cutlery items (e.g., into second aperture 112) into device 100 to be polished and/or dried, as described herein. Integrating the cutlery and glass polishing/drying capability into a single device eliminates the need to have separate discrete devices dedicated to cleaning of stemware or cutlery.
Although the apertures 110, 112, 122 are illustrated in
Device 100 includes substantially similar electronic components as device 10. For example, device 100 includes at least one of the electric drive 24, the steam distribution system 34, a boiler 38 for heating the water of the steam distribution system 34, and other electrical components of device 10 not specifically shown with respect to device 100, including, but not limited to, the rotating assembly 32, the water reservoir 36, the main water connection 37, the pump 42 of the steam distribution system 34, and other suitable components that allow devices 10 and 100 to function as described herein.
Device 100 includes a wall 132 that is configured to separate the cleaning elements 16 from the electrical components. The wall 132 protects the electrical components of device 100 from the steam emitted from the cleaning elements 16 in the polishing and/or drying of the items inserted into the enclosure 102 (shown in
As shown in
An anchor member 142 is made integral with the collar 130. In the exemplary embodiment, the anchor 142 is an L-shaped member. A free end 147 of the anchor member 142 is fixed in a conventional manner to an interior of side portion 106a near the top portion 104 of the enclosure 102 when the channel assembly 114 is located in the chamber 103. Screws, or other well-known fasteners may be used to join the free end 147 of the anchor member 142 to the enclosure 102.
A second anchor member 144 is made integral with chute 124 and includes a first leg 150 and a second leg 152. In the exemplary embodiment, the second anchor member 144 is U-shaped. The second anchor member 144 secures the channel assembly 114 to the enclosure 102 along a floor of the enclosure 102 (e.g., the floor of the enclosure being substantially parallel to the top portion 104 of the enclosure 102, shown in
Accordingly, when located for use in the chamber 103, the first anchor member 142 of the channel assembly 114 is secured in the enclosure 102 of the device 100 such that (i) the collar 130 and associated defined inlet 125 is adjacent the second aperture 112 of the device 100 and (ii) the discharge end 123 of the chute assembly 114 is adjacent the third aperture 122 with the guides 146, 148 adjacent the third aperture 122 (as shown in
In use, cutlery, such as forks, knives and/or spoons may be inserted through inlet 125 and second aperture 112 into chamber 103. Upon entry into the chamber 103, the specific cutlery item is located along the portion of the path 149 defined by the support 140. The cutlery item then moves through the cleaning elements 16f, 16g where the item is polished and/or dried. After passing through the cleaning elements 16f, 16g, the cutlery item continues along the portion of the path 149 defined by the chute 124 and ultimately exits (e.g., is discharged from) the chamber 103 through third aperture 124. The guide members 146, 148 ensure that as the cutlery item emerges from the cleaning elements 16f, 16g, it is maintained on the defined path 149 and out the third aperture 122. The guides 146, 148 span the entire length of the chute 124, from the cleaning elements 16f, 16g to the discharge end 123. In some embodiments, as the cutlery exits the chamber 103, the cutlery may be collected in a receptacle (not shown) located near the third aperture 122, thereby further minimizing contact with the cleaned cutlery. In other embodiments, a user may receive the polished and/or dried cutlery items as the cutlery items descend from the chute 124 and out of the chamber 103.
With the addition of the channel assembly 114 of the device 100, the device 100 can automatically polish and/or dry, by the cleaning elements 16f, 16g, the cutlery items inserted into the second aperture 112 of the top portion 104 of device 100. That is, device 100 embodies a “touchless” system for polishing and/or drying cutlery items. The user of device 100 does not have to hold the items in contact with the cleaning elements 16f, 16g while the cleaning elements 16f, 16g polish and/or dry the cutlery items. Rather, the user of device 100 may insert the cutlery items in the second aperture 112 of the top portion 104 of the device 100 and retrieve the inserted cutlery items from the third aperture 122 of the side panel 120 of device 100. Accordingly, the “touchless” polishing and/or drying functionality of device 100 provides a sanitary, fast, and efficient way for users to polish and/or dry cutlery items.
In the exemplary embodiment, the brush head assemblies 350 of each of the cleaning elements 16a-g are substantially similar. Accordingly, only one brush head assembly 350 is illustrated, and it should be understood that in the exemplary embodiment, the brush head assembly 350 represents the brush head assemblies 350 for each of the cleaning elements 16a-g. In other embodiments, the brush head assemblies 350 of the cleaning elements 16a-g may differ from one another. For example, in one embodiment, the cleaning elements 16a-e may include larger brush head assemblies 350 compared to the brush head assemblies 350 of the cleaning elements 16f, 16g.
The glass tube 210 includes two apertures 212 disposed 180 degrees from each other on the glass tube 210. The glass tube 210 is configured to be disposed around the steam shaft 204 of the steam generating component 200. The apertures 212 of the glass tube 210 are configured to align with the apertures 208 of the steam shaft 204 when the glass tube 210 is disposed around the steam shaft 204. That is, when the steam flows radially outward from the steam pipe 206, the steam flows through the apertures 208 of the steam shaft and the apertures 212 of the glass tube of the brush head assembly 350.
The band 300 includes a front end 302 and a back end 304 opposite the front end 302. The band 300 includes a plurality of brush tassels 306 sewn or otherwise joined together to form the band 300. In the exemplary embodiment, the brush tassels 306 are comprised of a mix of fibers of cotton, rayon, and polyester. In other embodiments, the brush tassels are comprised of any suitable fibers or materials including, for example, foam. The band 300 includes an adhesive 308 adhered to the back end 304 of the band 300. In the exemplary embodiment, the adhesive 308 is a double-sided cloth tape. In other embodiments, the adhesive 308 is any suitable adhesive including, for example, glue, hook-and-loop fasteners, and resins.
The brush head assembly 350 includes the glass tube 210 and the band 300 of the plurality of brush tassels 306. Specifically, the brush assembly 350 is formed from the band 300 being adhered to the glass tube 210 with the adhesive 308 of the band 300. The band 300 is wound tightly around the glass tube 210, except in the areas of the apertures 212 of the glass tube 210. That is, the band 300 is not adhered to the apertures 212 of the glass tube 210. Accordingly, the brush assembly 350 is disposed around the steam generating component 200 such that steam flows from the steam generating component 200 through the apertures 212 and brush assembly 350. The steam and the rotation of the plurality of brush tassels 306 polish and/or dry the items inserted into the enclosure 102 of the device 100 (both shown in
The embodiments have been described by way of example only and modifications are possible within the scope of the disclosure disclosed. For example, in the illustrated embodiments, the cleaning elements 16 are rotatable for cleaning or polishing the items. In other embodiments, the direction of motion may change rapidly with the cleaning elements 16 oscillating. In other embodiments, the cleaning elements may also demonstrate axial movement, or combinations or rotation, oscillation and axial translation. Furthermore, although the cleaning elements are described as being formed of flexible filaments that are urged outwardly during rotation, they may also be formed of other materials, such as plastic foams for example.
