It is contemplated that, in other embodiments, the fluid heating appliance may be any suitable type of appliance that heats fluid (i.e., gas or liquid) for any suitable purpose without departing from the scope of this invention (e.g., the fluid heating appliance may be a hot water dispenser in some embodiments).
- the fluid heating appliance may be any suitable type of appliance that heats fluid (i.e., gas or liquid) for any suitable purpose without departing from the scope of this invention (e.g., the fluid heating appliance may be a hot water dispenser in some embodiments).
- the illustrated coffeemaker 100 includes a housing 102 , a filter basket 104 detachably mounted on (e.g., suspended from) the housing 102 , and a hot plate 106 situated beneath the filter basket 104 .
- the coffeemaker 100 is configured to receive a carafe (e.g., a coffee pot 108 ) on the hot plate 106 beneath the filter basket 104 for containing a brewed beverage (e.g., coffee) discharged from the filter basket 104 during a brewing operation.
- a carafe e.g., a coffee pot 108
- At least one window is provided on the housing 102 , namely a pair of opposing first windows 110 and a pair of opposing second windows 112 in the illustrated embodiment.
- the coffeemaker 100 may be configured in any suitable manner that facilitates enabling the coffeemaker 100 to heat liquid as described herein (e.g., the coffeemaker 100 may not have the detachable filter basket 104 , the hot plate 106 , and/or the windows 110 , 112 in some contemplated embodiments).
- the illustrated coffeemaker 100 further includes a reservoir 114 , a showerhead 116 , and a flow control system (indicated generally by reference numeral 118 ) for regulating a flow of liquid from the reservoir 114 to the showerhead 116 .

- the flow control system 118 includes a pump 120 , a holding tank 122 , and a heating device (indicated generally by reference numeral 124 ) connected in flow communication with one another by a suitable network of conduits.
- the network includes: an upstream conduit 126 which connects the reservoir 114 to the pump 120 ; a column conduit 128 which connects the pump 120 to the holding tank 122 ; a downstream conduit 130 which connects the holding tank 122 to the heating device 124 ; and a ventilation conduit 132 which connects the holding tank 122 to the exterior of the housing 102 for ventilating the network to the ambient.
- the flow control system 118 may have any suitable components arranged in any suitable manner that facilitates supplying liquid from the reservoir 114 to the heating device 124 (e.g., the flow control system 118 may not include the pump 120 and/or the holding tank 122 in some contemplated embodiments, or the flow control system 118 may have a different network of conduits in other embodiments).
- the heating device 124 includes at least one thin-film heating element, namely a first heating element 136 and a second heating element 138 in the illustrated embodiment.
- the heating device 124 may be configured with any suitable number of thin-film heating elements (e.g., the heating device 124 may have only one heating element in some embodiments, or the heating device 124 may have more than two heating elements in other embodiments).
- each of the heating elements 136 , 138 is tubular and has a first end 140 , a second end 142 , and a multi-layer body 144 extending from the first end 140 to the second end 142 .
- the body 144 has a radially inner layer in the form of a substrate 146 , and a radially outer layer in the form of an electrically conductive material 148 deposited on the substrate 146 .
- each heating element 136 , 138 of the heating device 124 is said to be a “thin-film” heating element in the sense that the substrate 146 and the electrically conductive material 148 have a collective thickness that is only marginally greater than the thickness of the substrate 146 itself (i.e., the material 148 forms a thin film on the substrate 146 ).
- the first heating element 136 and the second heating element 138 are substantially identical (i.e., are made in the same manner using the same materials so as to have the same overall construction within accepted manufacturing tolerances).
- the substrate 146 of the heating elements 136 , 138 may be a glass substrate (e.g., a borosilicate substrate, a quartz substrate, etc.), and the electrically conductive material 148 of the heating elements 136 , 138 may be a metal oxide material (e.g., a tin oxide material).
- the first heating element 136 is shown in FIGS. 7 and 8 , it is understood that the second heating element 138 is configured to be substantially identical.
- the heating elements 136 , 138 may not be substantially identical (e.g., the first heating element 136 may have its substrate 146 made of a first composition, and its electrically conductive material 148 made of a second composition; whereas the second heating element 138 may have its substrate 146 made of a third composition that is different than the first composition, and its electrically conductive material 148 made from a fourth composition that is different than the second composition).
- each heating element 136 , 138 of the heating device 124 may have its substrate 146 and its electrically conductive material 148 made from any suitable composition(s) that facilitate enabling the heating element(s) 136 , 138 to function as described herein.
- the substrate 146 forms at least a segment of an interior surface 150 of the body 144 , and the interior surface 150 defines a heating conduit 152 which extends through the body 144 from the first end 140 to the second end 142 .
- an additional layer of the body 144 e.g., a coating
- the electrically conductive material 148 forms at least a segment of an exterior surface 154 of the body 144 .
- the electrically conductive material 148 completely covers the radially outer side of the substrate 146 , in the sense that the material 148 wraps completely around the substrate 146 from near the first end 140 to near the second end 142 .
- the material 148 may not completely cover the radially outer side of the substrate 146 but, rather, may instead be deposited on the substrate 146 in any suitable pattern (e.g., the material 148 may be deposited in a pattern of circumferentially spaced-apart lines, or a grid-like formation, that extends from near the first end 140 to near the second end 142 ).
- the body 144 e.g., the substrate 146 and the electrically conductive material 148
- the illustrated coffeemaker 100 has a light source (e.g., at least one light emitting diode (LED) 156 ) for emitting light (e.g., a colored light such as red light, green light, blue light, etc.) through the heating conduit 152 to illuminate the liquid disposed within the heating conduit 152 .
- a light source e.g., at least one light emitting diode (LED) 156
- LED light emitting diode
- the LEDs 156 facilitate illuminating bubbles in the liquid when the heating elements 136 , 138 heat the liquid and as the bubbles rise through the heating conduit 152 ). While the illustrated LEDs 156 are disposed near the first ends 140 of the heating elements 136 , 138 as set forth in more detail below, the LEDs 156 may be disposed at any suitable location(s) in other embodiments. Alternatively, the body 144 (e.g., the substrate 146 and/or the electrically conductive material 148 ) may be opaque (and the LEDs 156 therefore absent from the coffeemaker construction) without departing from the scope of this invention.
- the heating elements 136 , 138 are oriented substantially parallel to one another and are held in spaced-apart relation via a grommet (or spacer) 158 , and the grommet 158 engages a bracket 161 of the housing 102 to facilitate stabilizing the heating elements 136 , 138 within the housing 102 .
- each of the heating elements 136 , 138 is attached at its first end 140 to a one-way (or check) valve 162 via a first coupling 164 such that the heating conduit 152 is in flow communication with the downstream conduit 130 across the one-way valve 162 .
- Each of the heating elements 136 , 138 is also attached at its second end 142 to the showerhead 116 via a second coupling 166 such that the heating conduit 152 is in flow communication with the showerhead 116 .

Abstract
A coffeemaker generally includes a reservoir and a flow control system for regulating a flow of water from the reservoir. The flow control system has a thin-film heating element that defines at least a portion of a heating conduit in which water is heated.
Description
- This application claims the benefit of U.S. Provisional Application No. 61/980,468 filed on Apr. 16, 2014, which is incorporated by reference herein in its entirety.
- The present invention relates generally to fluid heating appliances and, more particularly, to an appliance for brewing a beverage (e.g., a coffeemaker).
- Many conventional coffeemakers have a water reservoir, a showerhead, and a flow control system. The flow control system includes an arrangement of tubes and a pump for generating a flow of water from the reservoir to the showerhead through the tubes. At least some conventional coffeemakers also include a calrod-type heating device that heats the water as the water flows from the reservoir to the showerhead. However, it can be difficult to regulate water temperature with calrod-type heating devices, not to mention the less than desirable heat-up time and bulkiness of calrod-type heating devices.
- It would be useful, therefore, to provide a coffeemaker with a smaller heating device that enables water to be heated quicker and to a more precise temperature.
- In one embodiment, a coffeemaker generally comprises a reservoir and a flow control system for regulating a flow of water from the reservoir. The flow control system includes a thin-film heating element that defines at least a portion of a heating conduit in which water is heated.
- In another embodiment, a coffeemaker generally comprises a reservoir, a showerhead, and a flow control system for regulating a flow of water from the reservoir to the showerhead. The flow control system includes a thin-film heating element that defines a heating conduit in which water is heated. The flow control system further includes a check valve disposed between the reservoir and the heating element, and a flow control valve disposed between the heating element and the showerhead.
- In yet another embodiment, a terminal unit for a heating device having a pair of tubular, thin-film heating elements generally comprises a pair of ring-shaped terminals each sized to wrap around one of the heating elements. The terminal unit also includes a bus bar extending between the ring-shaped terminals to electrically connect the ring-shaped terminals to one another.

- Referring to the drawings, and in particular to
FIGS. 1 and 2 , a fluid heating appliance is illustrated in the form of a coffeemaker (indicated generally by the reference numeral 100). It is contemplated that, in other embodiments, the fluid heating appliance may be any suitable type of appliance that heats fluid (i.e., gas or liquid) for any suitable purpose without departing from the scope of this invention (e.g., the fluid heating appliance may be a hot water dispenser in some embodiments). - The illustrated
coffeemaker 100 includes ahousing 102, afilter basket 104 detachably mounted on (e.g., suspended from) thehousing 102, and ahot plate 106 situated beneath thefilter basket 104. In this manner, thecoffeemaker 100 is configured to receive a carafe (e.g., a coffee pot 108) on thehot plate 106 beneath thefilter basket 104 for containing a brewed beverage (e.g., coffee) discharged from thefilter basket 104 during a brewing operation. - To enable viewing of internal componentry of the
coffeemaker 100 during its operation, at least one window is provided on thehousing 102, namely a pair of opposingfirst windows 110 and a pair of opposingsecond windows 112 in the illustrated embodiment. In other embodiments, however, thecoffeemaker 100 may be configured in any suitable manner that facilitates enabling thecoffeemaker 100 to heat liquid as described herein (e.g., thecoffeemaker 100 may not have thedetachable filter basket 104, thehot plate 106, and/or thewindows - With reference now to
FIG. 3 , the illustratedcoffeemaker 100 further includes areservoir 114, ashowerhead 116, and a flow control system (indicated generally by reference numeral 118) for regulating a flow of liquid from thereservoir 114 to theshowerhead 116. Thereservoir 114 is configured to contain a liquid suitable for brewing a beverage (e.g., water), and the amount of liquid contained within thereservoir 114 is observable through thefirst windows 110. Theshowerhead 116 is situated, at least in part, above thefilter basket 104 for discharging liquid onto a brewable product (e.g., coffee grounds) placed on a filter inside thefilter basket 104. - The flow control system 118 includes a
pump 120, aholding tank 122, and a heating device (indicated generally by reference numeral 124) connected in flow communication with one another by a suitable network of conduits. In the illustrated embodiment, the network includes: anupstream conduit 126 which connects thereservoir 114 to thepump 120; acolumn conduit 128 which connects thepump 120 to theholding tank 122; adownstream conduit 130 which connects theholding tank 122 to theheating device 124; and aventilation conduit 132 which connects theholding tank 122 to the exterior of thehousing 102 for ventilating the network to the ambient. Alternatively, the flow control system 118 may have any suitable components arranged in any suitable manner that facilitates supplying liquid from thereservoir 114 to the heating device 124 (e.g., the flow control system 118 may not include thepump 120 and/or theholding tank 122 in some contemplated embodiments, or the flow control system 118 may have a different network of conduits in other embodiments). - As shown in
FIGS. 4 and 5 , theheating device 124 includes at least one thin-film heating element, namely afirst heating element 136 and asecond heating element 138 in the illustrated embodiment. Without departing from the scope of this invention, theheating device 124 may be configured with any suitable number of thin-film heating elements (e.g., theheating device 124 may have only one heating element in some embodiments, or theheating device 124 may have more than two heating elements in other embodiments). - Referring now to
FIGS. 7 and 8 , each of theheating elements first end 140, asecond end 142, and a multi-layer body 144 extending from thefirst end 140 to thesecond end 142. The body 144 has a radially inner layer in the form of a substrate 146, and a radially outer layer in the form of an electrically conductive material 148 deposited on the substrate 146. As used herein, eachheating element heating device 124 is said to be a “thin-film” heating element in the sense that the substrate 146 and the electrically conductive material 148 have a collective thickness that is only marginally greater than the thickness of the substrate 146 itself (i.e., the material 148 forms a thin film on the substrate 146). - In the illustrated embodiment, the
first heating element 136 and thesecond heating element 138 are substantially identical (i.e., are made in the same manner using the same materials so as to have the same overall construction within accepted manufacturing tolerances). For instance, the substrate 146 of theheating elements heating elements first heating element 136 is shown inFIGS. 7 and 8 , it is understood that thesecond heating element 138 is configured to be substantially identical. - In other embodiments, the
heating elements first heating element 136 may have its substrate 146 made of a first composition, and its electrically conductive material 148 made of a second composition; whereas thesecond heating element 138 may have its substrate 146 made of a third composition that is different than the first composition, and its electrically conductive material 148 made from a fourth composition that is different than the second composition). Alternatively, eachheating element heating device 124 may have its substrate 146 and its electrically conductive material 148 made from any suitable composition(s) that facilitate enabling the heating element(s) 136, 138 to function as described herein. - In the illustrated embodiment, the substrate 146 forms at least a segment of an
interior surface 150 of the body 144, and theinterior surface 150 defines aheating conduit 152 which extends through the body 144 from thefirst end 140 to thesecond end 142. In an alternative embodiment, an additional layer of the body 144 (e.g., a coating) may be disposed on a radially inner side of the substrate 146 such that the additional layer forms some or all of theinterior surface 150. - The electrically conductive material 148, on the other hand, forms at least a segment of an
exterior surface 154 of the body 144. For example, in the illustrated embodiment, the electrically conductive material 148 completely covers the radially outer side of the substrate 146, in the sense that the material 148 wraps completely around the substrate 146 from near thefirst end 140 to near thesecond end 142. In another contemplated embodiment, the material 148 may not completely cover the radially outer side of the substrate 146 but, rather, may instead be deposited on the substrate 146 in any suitable pattern (e.g., the material 148 may be deposited in a pattern of circumferentially spaced-apart lines, or a grid-like formation, that extends from near thefirst end 140 to near the second end 142). - Referring back to
FIGS. 4 and 5 , the body 144 (e.g., the substrate 146 and the electrically conductive material 148) are substantially transparent in the illustrated embodiment, thereby enabling liquid within theheating conduit 152 to be viewed from outside of thehousing 102 through thesecond windows 112. In this manner, the illustratedcoffeemaker 100 has a light source (e.g., at least one light emitting diode (LED) 156) for emitting light (e.g., a colored light such as red light, green light, blue light, etc.) through theheating conduit 152 to illuminate the liquid disposed within theheating conduit 152. This enhances the overall aesthetic appeal of thecoffeemaker 100 during operation (e.g., the LEDs 156 facilitate illuminating bubbles in the liquid when theheating elements first ends 140 of theheating elements - In the illustrated embodiment, the
heating elements grommet 158 engages a bracket 161 of thehousing 102 to facilitate stabilizing theheating elements housing 102. Moreover, each of theheating elements first end 140 to a one-way (or check)valve 162 via afirst coupling 164 such that theheating conduit 152 is in flow communication with thedownstream conduit 130 across the one-way valve 162. Each of theheating elements second end 142 to theshowerhead 116 via a second coupling 166 such that theheating conduit 152 is in flow communication with theshowerhead 116. - In the illustrated embodiment, the
couplings 164, 166 are fabricated from a material that facilitates electrically and thermally isolating theheating elements way valve 162 and theshowerhead 116, respectively (e.g., thecouplings 164, 166 may be fabricated from a plastic or rubber material). Moreover, the one-way valve 162 is substantially transparent in the illustrated embodiment, and the LEDs 156 are mounted beneath the one-way valve 162 on aledge 160 of thehousing 102 to emit light through the one-way valve 162 into theheating conduit 152. - The illustrated
heating device 124 further includes afirst terminal 168 and asecond terminal 170 attached to each of theheating elements first terminal 168 is ring-shaped and wraps around the body 144 near thefirst end 140 in electrical contact with the material 148. Similarly, thesecond terminal 170 is ring-shaped and wraps around the body 144 near thesecond end 142 in electrical contact with the material 148. In alternative embodiments, theterminals heating elements - Referring now to
FIGS. 5 and 6 , thefirst terminals 168 are electrically connected to one another via afirst bus bar 172 to form a first terminal unit (indicated generally by reference numeral 174), thereby enabling electrical current to flow from one of thefirst terminals 168 to the other of thefirst terminals 168 across thefirst bus bar 172. Similarly, thesecond terminals 170 are electrically connected to one another via a second bus bar 176 to form a second terminal unit (indicated generally by reference numeral 178), thereby enabling electrical current to flow from one of thesecond terminals 170 to the other of thesecond terminals 170 across the second bus bar 176. Because the firstterminal unit 174 and the secondterminal unit 178 are substantially identical in the illustrated embodiment, only the firstterminal unit 174 is represented inFIG. 6 . - In some contemplated embodiments the
first terminals 168 may not be electrically connected to one another via thefirst bus bar 172, and thesecond terminals 170 may not be electrically connected to one another via the second bus bar 176. Moreover, in other contemplated embodiments, theterminal units terminal unit 174 may have fourfirst terminals 168 electrically connected together by thefirst bus bar 172 if theheating device 124 has four heating elements). Alternatively, the material 148 may not extend from near thefirst end 140 to near thesecond end 142, but may instead be limited to a central region of the body 144 such that theterminals ends - In the illustrated embodiment, each of the
terminals wire port 180 that facilitates electrically connecting wires to theterminal units terminals heating element housing 102 or a remote power supply) via the wires. - When electrical current is thereby supplied to each
heating element first terminal 168 to thesecond terminal 170 across the electrically conductive material 148. Because the material 148 naturally resists the flow of current therethrough, the material 148 heats up as a result. Such heating of the material 148 causes the substrate 146 to be heated by virtue of the substrate 146 being in conductive heat transfer with the material 148. This facilitates heating any fluid (e.g., water) disposed within theheating conduits 152. - In the illustrated embodiment, the electrical current supplied to the electrically conductive material 148 is regulated by a control unit 182 (shown in
FIG. 3 ) disposed within thehousing 102. More specifically, thecontrol unit 182 modulates the flow of electrical current from the power supply through the electrically conductive material 148 during operation of thecoffeemaker 100 to control the temperature of the substrate 146 and, hence, the temperature of the liquid flowing through theheating conduits 152. - Optionally, the
control unit 182 may be operatively connected to a suitable temperature sensor (e.g., abimetallic temperature switch 184, shown inFIGS. 3 and 4 ) for regulating a temperature of theheating elements 136, 138 (such as, for example, to facilitate preventing theheating elements control unit 182 suitably includes a microcontroller and a memory for storing instructions to be executed by the microcontroller when modulating electrical current to the heating element(s) 136, 138 in response to a selection by the user. - In one example of operating the
coffeemaker 100 to brew coffee, the user presses a button on an interface of the coffeemaker 100 (or a remote interface, such as a wireless device). Thecontrol unit 182 responds by supplying electrical current to theheating elements heating element terminals substrate 136 and, hence, the temperature inside theheating conduit 152. - Before, during, or after supplying current to the
heating elements control unit 182 also operates thepump 120 to supply water from thereservoir 114 to theheating elements conduits heating conduits 152 via the one-way valve 162. As the temperature of the water within theheating conduits 152 is raised and the pressure inside theheating conduits 152 increases, the water evacuates theheating conduits 152 into thefilter basket 104 via theshowerhead 116. Once theheating conduits 152 have been at least partially evacuated, additional water is permitted to flow into theheating conduits 152 via the one-way valve 162. - As shown in
FIG. 3 , because the illustratedholding tank 122 is elevated in relation to the max-fill marker 134 of the reservoir 114 (and in relation to the one-way valve 162), theholding tank 122 gravitationally pressurizing the water flowing from thereservoir 114 to theheating device 124 to facilitate ensuring that water is supplied to theheating elements reservoir 114 is low. - Optionally, in some contemplated embodiments (e.g., embodiments that do not include the pump 120), a flow control valve 186 may be disposed between the heating element(s) 136, 138 and the
showerhead 116, as shown schematically inFIG. 9 . In this manner, the flow control valve 186 may be configured to prevent the heated water from prematurely evacuating the heating conduit(s) 152 until a predetermined water temperature is reached. For example, thecontrol unit 182 may be configured to operate the flow control valve 186 to inhibit the heated water from prematurely evacuating the heating conduit(s) 152 until a predetermined water temperature is reached. Thus, in some embodiments, the water may be heated to a desired temperature, which is selectable from a plurality of predetermined temperatures. - Referring now to
FIGS. 10 and 11 , rather than havingheating device 124 andshowerhead 116, thefluid heating appliance 100 may instead have a heating device (indicated generally by reference numeral 188) and associatedshowerhead 190. In the illustrated embodiment, theheating device 188 includes a frame 192 (e.g., a silicone frame) and a pair of thin-film heating elements 194 mounted in spaced relation on theframe 192 such that theframe 192 substantially seals around the bottom and sides of eachheating element 194. - The
heating elements 194 are in the form of substantially rectangular panes (e.g., are substantially planar objects), such that aheating conduit 196 having an open-top, generally cuboidal volumetric shape is defined between theheating elements 194. A one-way valve 198 is connected to theframe 192 in flow communication with the bottom of theheating conduit 196, and theshowerhead 190 is connected to theframe 192 in flow communication with the open top of theheating conduit 196. The one-way valve 198 is also configured for connection to thedownstream conduit 130 to place thedownstream conduit 130 in flow communication with theheating conduit 196 across the one-way valve 198. Optionally, in an alternative embodiment, theheating device 188 may have only oneheating element 194, with an additional sidewall of theframe 192 in place of theother heating element 194, for example. - Each of the
heating elements 194 is constructed much like theheating elements heating element 194 has a substrate, an electrically conductive material deposited on the substrate, and a pair ofbus bars 199 suitably attached to, or deposited on, the substrate. When electrical current is supplied to the bus bars 199 by thecontrol unit 182, the current flows across the electrically conductive material and heats the substrate to, in turn, heat theconduit 196. Water in theconduit 196 is heated as a result, and the heated water evacuates theconduit 196 toward the open top of theconduit 196 and spills over into theshowerhead 190 for delivery to thefilter basket 104. - Moreover, the
heating device 188 may be viewable through the window(s) 112 of thehousing 102, and may be illuminated by the light source (e.g., the LEDs 156), in a manner similar to that ofheating device 124 set forth above.
