DETAILED DESCRIPTION

(15) In the present description, certain terms have been used for brevity, clarity and understanding. No unnecessary limitations are to be inferred therefrom beyond the requirement of the prior art because such terms are used for descriptive purposes only and are intended to be broadly construed. The different apparatuses described herein may be used alone or in combination with other apparatuses. Various equivalents, alternatives and modifications are possible within the scope of the appended claims.

(16) Through research and experimentation, the present inventors have recognized that beverage dispensing machines with discrete post-mix beverage dispensing heads (which dispense a single type of beverage from a single nozzle) do not include apparatuses for illuminating the housing of the beverage dispensing heads, the dispensing beverage, and/or working areas (e.g. drip tray) of the dispensing machines. The present inventors have also recognized that the lights that illuminate working areas of beverage dispensing machines having multi-flavor post-mix beverage dispensing heads (which dispense different flavors of beverages from a single nozzle) are not easily integrated into beverage dispensing machines with discrete post-mix beverage dispensing heads. Through research and experimentation, the present inventors have developed the presently disclosed lighting modules, which can be coupled to the discrete post-mix beverage dispensing heads. The present inventors have developed lighting modules that are self-contained and can be connected to the existing electrical circuit that provides power to the discrete post-mix beverage dispensing head.

(17) Prior art post-mixed beverage dispensing heads commonly used in the industry receive two independent fluids (e.g. a flavor syrup and carbonated water) and dispense a beverage formed from the two fluids. Reference is made to the above-incorporated U.S. Patent Application and U.S. Patents for further description of the components and operation of the prior art post-mixed beverage dispensing heads.

(18) Referring to FIG. 1, a beverage dispensing machine 10 has a plurality of post-mix beverage dispensing heads 20 for dispensing beverages to an operator. The beverage dispensing machine 10 includes a drip tray 14 for collecting any beverage that may spill during operation. The beverage dispensing machine 10 has a front side 11 for filing beverage receptacles (e.g. cups) with the beverage from the dispensing heads 20 and a rear side 12 opposite the front side 11 (which may be orientated toward a consumer). It will be recognized that each of the plurality of dispensing heads 20 in a beverage dispensing machine 10 can include any of the components and features described herein.

(19) Referring to FIGS. 2-4, each dispensing head 20 includes a housing 35 that covers and protects a valve assembly 22 (described further herein). The housing 35 includes a front 36, a rear 42 opposite the front 36, a base 45 that extends between the front 36 and the rear 42, and a top 46 opposite the base 45 that extends between the front 36 and the rear 42. The housing 35 defines a cavity 15 in which the valve assembly 22 and a lighting module 50 (described further herein) are disposed.

(20) The front 36 is removably coupled to the dispensing head 20 and includes a display window 38 that can be either transparent or translucent. The display window 38 is removably coupled to the front 36 (FIG. 5). The display window 38 can be made of any suitable transparent or translucent material including glass, plastic, and/or the like. The display window 38 is configured to receive a graphic (e.g. an adhesive sticker) that displays indicia that corresponds to the beverage dispensed from the dispensing head 20 (e.g. an adhesive sticker having a beverage brand or flavor name (e.g. Cherry Cola, Diet Cola) is received on the display window 38). In certain examples, the display window 38 is curved so as to form a lens for focusing light from the lighting module 50. The front 36 is removably coupled to the dispensing head 20 such that the removal of the front 36 exposes the internal components of the dispensing head 20 (FIG. 4).

(21) The rear 42 includes a rear display window 44 (FIG. 3) that can be either transparent or translucent. The rear display window 44 is removably coupled to the rear 42. The rear display window 44 is configured to receive a graphic, such as an adhesive sticker. The rear display window 44 can be made of any suitable transparent or translucent material including glass, plastic, and/or the like.

(22) The base 45 includes a lighting opening 47 (FIG. 3) that is separate from the display window 38. A mixing nozzle 32 is removably coupled to the base 45 and is configured to dispense a beverage to the operator via the base 45 to the beverage receptacle.

(23) Each dispensing head 20 further includes a valve assembly 22 (FIGS. 3-4) having a valve back block 24, a valve 26 configured to control flow of beverage through the mixing nozzle 32, and a switch 28 (FIG. 13) that is movable into and between a closed position in which the valve 26 opens the flow of beverage via the mixing nozzle 32 and an open position in which the valve 26 closes the flow of beverage via the mixing nozzle 32. The valve 26 can include any number of valves such as solenoid valves, check valves, and/or the like. Reference is made to the above incorporated U.S. Patents and U.S. Patent Application for further examples of valves for dispensing a beverage from the dispensing head 20.

(24) Each dispensing head 20 further includes a lever 30 that extends from the base 45 of the housing 35 and is coupled to the switch 28 such that movement of the lever 30 causes the switch 28 to move to the closed position the valve 26 opens the flow of beverage via the mixing nozzle 32 and the lighting module 50 illuminates. That is, the lever 30 is configured to activate flow of beverage via the mixing nozzle 32 by moving the switch 28 to a closed position. In one example operation, a beverage receptacle is pressed against the lever 30 such that the lever 30 causes the switch 28 to move to the closed position. Reference is made to the above incorporated U.S. Patents and U.S. Patent Application for further details regarding examples of a dispense of beverage from the dispensing head 20.

(25) Referring to FIGS. 7-11, the dispensing head 20 includes a lighting module 50 disposed in the cavity 15 (FIG. 8) defined by the housing 35. The lighting module 50 is configured to illuminate the front 36 of the housing 35 and the base 45 of the housing 35 when the switch 28 (FIG. 13) is moved into the closed position. That is, the lighting module 50 is configured to illuminate the display window 38 and/or the lighting opening 47 when the switch 28 is moved into the closed position. Illumination of the display window 38 can cause the graphic received on the display window 38 to illuminate and thereby display indicia to the operator. The lighting opening 47 is oriented toward the point of dispense of the beverage, i.e. the mixing nozzle 32, the flow of beverage into the beverage receptacle, and/or the drip tray. The illumination of the display window 38 and the lighting opening 47 can be simultaneous or sequential.

(26) The lighting module 50 includes a first light source 61 orientated toward the display window 38 that emits light and a second light source 71 orientated toward the lighting opening 47 that emits light. The light sources 61, 71 include at least one light emitting diode (LED), and the light sources 61, 71 can include a printed circuit board.

(27) The lighting module 50 further includes a light guide 52 that vertically upwardly guides light from the first lighting source 61 alongside the display window 38. In certain examples, the light guide 52 extends alongside a majority of the display window 38. The light guide 52 includes a front surface 53 for dispersing the light toward the display window 38 and a rear surface 54 opposite the front surface 53 that reflects light from the first light source 61 toward the display window 38 (see FIGS. 10 and 11 which include light arrows L that depict light directed toward the display window 38). The front surface 53 includes a diffuser film 63 that diffuses the light toward the display window 38. The rear surface 54 includes a reflective film 65 that reflects light from the first light source 61 toward the display window 38. The rear surface 54 has reflective properties that increase as the rear surface 54 extends away from the first light source 61 (i.e. the reflective properties of the rear surface 54 can include reflectivity, light absorption, light scattering, and/or the like, the strength of which increases further away from the first light source 61). In certain examples, the light guide 52 defines a cavity (not shown) that receives the light and vertically upwardly guides the light from the lighting source 61. The light guide 52 can be made of any suitable transparent or translucent material such as plastic, glass, and the like.

(28) The lighting module 50 is removably coupled to the housing 35 by a manually operable mating connection 66 (FIGS. 6-7). The mating connection 66 includes a boss 85 (FIG. 7) on one of the lighting module 50 and the housing 35 and a channel 40 (FIGS. 5-6) defined in the other of the lighting module 50 and the housing 35. The channel 40 is configured to receive the boss 85. In the example depicted in FIGS. 5-7, the boss 85 is on the lighting module 50 and the channel 40 is defined in the housing 35.

(29) The lighting module 50 is further electrically coupled to the dispensing head 20 by a manually operable electrical connection 73 (FIG. 7). The electrical connection 73 couples to lighting module 50 to the electrical circuit that receives power for a power source 90 (FIGS. 12-13) and that is electrically coupled to the valve 26 (FIGS. 12-13). In the example depicted in FIG. 7, the electrical connection 73 is a wire harness that has a male connection end 74 that is configured to mate with a female connection receiver (not shown) on the dispensing head 20 (FIG. 4).

(30) Referring to FIG. 7, the lighting module 50 includes a casing 80 that defines a cavity 88 that receives the light guide 52, the first light source 61, and/or the second light source 62 to thereby protect and seal the light guide 52, the first light source 61, and/or the second light source 62 from contaminants and moisture. The casing 80 includes a front panel 81 and a rear panel 82 opposite the front panel 81 that hermetically seals with the front panel 81. The front panel 81 includes a pair of opposing sides 84 that extend toward the rear panel 82. The front panel 81 is configured to allow light to travel from the light guide 52 to the display window 38 and/or the lighting opening 47. The panels 81, 82 can include transparent, translucent, and/or opaque sections.

(31) The rear panel 82 defines an opening 99 that allows the electrical connection 73 to be received there through while still maintaining the hermetic seal with the front panel 81. The rear panel 82 also defines an access opening 100 that receives a removable grommet 101. The grommet 101 can be removed to allow inspection and/or maintenance to the components in the casing 80.

(32) In certain examples, the dispensing head 20 includes a rear lighting module 51 (FIG. 3) configured to illuminate the rear display window 44 of the rear 42. The rear lighting module 51 is similar to the lighting module 50 and can include any of the components described with reference to the lighting module 50. In certain examples, the rear lighting module 51 includes a second manual electrical connection that electrically couples the rear lighting module to the dispensing head 20.

(33) Referring to FIGS. 12-13 example circuit diagrams for the dispensing head 20 and the lighting module 50 are shown. The lighting module 50 is coupled to the power source 90 via the electrical connection 73 (FIG. 7). In certain examples, the power source 90 is a 24 Volt AC power source. In certain examples, a slide switch 94 is included and configured to electrically uncouple to the second light source 71 from the circuit such that the second light source 71 does not emit light.

(34) The lighting module 50 and/or the electrical circuits to which the lighting module 50 is coupled via the electrical connection 73 can include electrical devices and/or components which vary the operation of the lighting module 50 (i.e. various electrical devices may cause the light sources 61, 71 to blink, dim, gradually illuminate, and/or perform other functions).
