Description:
BACKGROUND OF THE INVENTION 
     The present invention relates to a vending machine installation including a misting accessory which attracts customers and enhances awareness of the identity of the product being vended. The present invention also relates to a pavilion incorporating vending machines and an array of misting nozzle assemblies providing evaporative cooling to persons within the pavilion. More specifically, the present invention relates to a vending machine installation and a pavilion incorporating an accessory which interacts with customers visually, audibly and physically in order to convey the cooling and refreshing attributes of the product being vended to the customer. 
     Various auxiliary devices have previously been integrated into vending machines in order to attract customers&#39; attention and to increase sales of the products to be vended. These devices include talking devices which audibly communicate various messages, greetings and advertisements to customers, musical devices which output uplifting jingles and advertisements to customers, coupon dispensers which dispense discount coupons for future purchases of the products, and game devices such as video games which the customer can play in conjunction with the purchase of products being vended. 
     All of the above devices, integrated into vending machines, are utilized to attract customers to the vending machines and increase product awareness. 
     Recently, in order to further increase product awareness improved sign panels and associated graphics have been developed to visually illustrate attributes of products including the ability to cool and refresh the consumer. Various types of graphics include beds of ice, frosting or the like for conveying to the customer the refreshing and cooling characteristics of the product. The cooling and refreshing nature of the product are particularly important in environments where temperatures may be high, as in amusement parks visited during warm weather months. 
     It is generally known in amusement parks to provide enclosures which customers of the park may walk into and be sprayed with water, or a water mist, to cool them off on hot summer days. These cooling areas are popular and give temporary relief from the heat. 
     U.S. Pat. No. 5,497,633, issued to Michael Jones and Mark Hensley, discloses apparatuses in which evaporative cooling is provided by adding a water mist from a nozzle or nozzles to an air current produced by a blower and discharging the cloud-like mixture to the local atmosphere. 
     Known apparatuses for providing evaporative cooling, such as those disclosed in the Jones et al. patent, generally require high pressure water supplies in order to achieve satisfactory atomization within the mist nozzles. The equipment for supplying the high pressure water can be bulky and expensive. Also, these evaporative cooling apparatuses are generally used for sustained periods and are not particularly well suited for intermittent operation. 
     Known misting or cooling enclosures in amusement parks or other sites where people gather are not directly or interactively associated with the sale of beverages. Rather, they are provided as separate attractions to cool off customers of the amusement park, to make their stay more enjoyable on a hot summer day. 
     For conveying the cooling and refreshing attributes of vending products to customers of the vended products, it would be advantageous to be able to communicate with the customer beyond the normal visual communication provided by improved sign panels and graphics relating to the cooling and refreshing attributes of the products. It would additionally be advantageous to be able to audibly and physically communicate with the customer the refreshing attributes of the products to be vended in an interactive way associated with the vending of the products and the operation of the vending machines by the customer. 
     OBJECTS AND SUMMARY OF THE INVENTION 
     Accordingly, it is a primary object of the present invention to provide a vending machine installation including means for attracting customers to increase sales of the products and to enhance the awareness of product identity being dispensed from the machines.

     DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS 
     Referring to FIG. 1, there is illustrated a vending machine installation in accordance with the present invention which includes two independently operated side-by-side vending machines 10 and 10&#39;. Each unit has front and side panels 10A, 10B which may carry advertising graphics. As illustrated, the front panel of each vending machine carries a relieved representation of a bottle 12A corresponding to at least one of the products therein to be vended. The graphics surrounding the illustrated bottles depict a bed of ice chunks 12B. The bottles shown on the front panels of the vending machines are the Coca-Cola &#34;Contour&#34; bottle which is a registered trademark of The Coca-Cola Company. The front panels of each vending machine also carry an independently operable control panel 14 including a coin or paper currency slot 14A and product selection buttons 14B. 
     A misting accessory 16 is supported above the two side-by-side vending machines by structure (not shown) which permits removal of either vending machine for convenient servicing. As illustrated, the misting accessory includes a housing 17 in the shape of an ice bed 18 from which extends a bottle neck 20. A cap 20A is mounted to the bottle neck for pivoting movement to a position which simulates the opening of the bottle. Angularly spaced ports 22 in the bottle neck accommodate nozzle assemblies (to be described) from which a cooling mist 24 discharges in the direction of a vending machine customer 26. A panel 19 incorporating a display 19A and speakers 19B at each end extends along the front of the housing 17. Located within and concealed by the housing are the components for generating a cooling mist, sounds and visual messages and for moving the bottle cap, as will be described. 
     As illustrated schematically in FIG. 2, vending machines 10 and 10&#39; each include a vend control unit 30 for receiving currency input signals at 14A in conjunction with product selection signals at input 14B through an AND gate or the like. Receipt of these signals causes the vending of a selected product by providing a signal to vend motors 32 in a known manner. The vend control unit 30 also provides signals to an interface device control unit 34. A readily available programmable logic controller 36 receives signals from the vending machines via the interface device control units 34. Controller 36 provides signals which operate sound generator 38, display 19A, motor 40 for pivoted bottle cap 20A and mist nozzle assemblies 60, 60&#39;. 
     An array of LEDs may serve as the display 19A, and a micro-chip, CD player or tape player may serve as the sound generator 38, which is connected to the speakers 19B on panel 19. As illustrated, the bottle cap 20A is operated by an air motor 40 coupled by conduit 42 to pressurized air supply 50. An air motor valve 42V in conduit 42 is coupled to controller 36 via line 42C and operates in response to signals from the controller to control the application of pressurized air to motor 40. 
     Each mist nozzle assembly includes a mist nozzle 62, 62&#39; and an adjacent air nozzle 64, 64&#39;. Water at a suitable pressure of, say, 30 psi is conveyed from water supply 52 to the mist nozzles via conduits 66, 66&#39;. Air at a suitable pressure of, say, 30 psi is conveyed from air supply 50 to the mist nozzles via conduits 68, 68&#39; and to the air nozzles via conduits 70, 70&#39;. The mist nozzles may be chosen from readily available nozzles which mix relatively low pressure water and air and produce a water/air mist cloud containing very fine water droplets. The air nozzles may be formed by small diameter tubing and are oriented so that they discharge an air current which intersects with the mist issuing from the discharge outlet of the adjacent mist nozzle. The mist and air nozzles may alternatively be incorporated in a unitary nozzle body. 
     If deemed advantageous, the cooling mist may carry an aroma which is evocative of a beverage flavor, or some other pleasing flavor or scent. The aroma can be provided by an aromatic agent supplied as an aerosol from pressurized source 54 connected by conduits 56, 56&#39; with air conduits 70, 70&#39;. The flow of the aromatic agent into the air conduits is controlled by valves 56V, 56V&#39; which operate in response to signals received from controller 36 via lines 56C, 56C&#39;. 
     Valves 66V, 66V&#39;, 68V, 68V&#39;, 70V, 70V&#39; in the water and air conduits are coupled to controller 36 via lines 66C, 66C&#39;, 68C, 68C&#39;, 70C, 70C&#39; and operate in response to signals from the controller to control the flow of water and air to the mist nozzle assemblies. 
     In a typical operating scheme, when a sale is not taking place at one of the vending machines, advertising or promotional messages will be presented on display 19A, and advertising jingles or sounds which attract customers will be produced by speakers 19B. Preferably, the sounds will suggest the cooling and refreshing effects of the products offered by the vending machines or the refreshing effects of the cooling mist emitted by the misting accessory. The sounds of ice falling into a glass, a beverage being poured into a glass, a satisfied &#34;ahhh&#34; voiced by a refreshed customer are among the sounds which might be employed. The water and air valves and the air motor valve may be periodically operated to discharge a mist from either or both of the mist nozzle assemblies and effect opening of the bottle cap. As will be described, the mist discharge will be accompanied by a sound, like the familiar sound of CO 2  gas escaping from a beverage container being opened, which may serve as an enticement to potential customers. 
     To make a purchase at one of the vending machines, the customer will introduce the necessary amount of currency into slot 14A and will select a product by actuating one of the buttons 14B. The vend control unit 30 then issues a signal which activates the vend motors 32 and also issues a signal to controller 36 via the interface device control unit 34. In response to the signal from the vending machine, the controller 36 issues signals via the control lines to open the valves in the water and air conduits for predetermined intervals for producing a cooling mist which discharges from a mist nozzle assembly toward the customer located in front of the vending machine. Concurrently, the controller 36 sends a signal to valve 42V which operates the air motor 40 to pivot the bottle cap toward an open position. Also, signals may be issued by the controller to change the sounds produced by the speakers 19B and the appearance of display 19A, so that potential customers nearby will be alerted to the cooling and refreshing experience of the customer who has made a purchase. The sounds may simulate the familiar sound of a beverage container being opened. 
     If the customer is making a purchase from vending machine 10&#39;, the controller will issue signals for operating the valves in the water and air conduits supplying mist nozzle assembly 60&#39;. The signals for operating the valves issue in a sequence which reliably produces a cloud-like mist directed toward the customer using vending machine 10&#39;. First, the valves 68V and 70V in conduits 68 and 70 are operated to allow flow of pressurized air to the mist and air nozzles 62&#39;, 64&#39;. Then, valve 66V&#39; in conduit 66 is operated for a suitable interval to allow a flow of water to the mist nozzle. Valves 68V&#39; and 70V&#39; allow continued air flow through the mist and air nozzles for a suitable interval after the water flow stops. 
     The initial air flow to the mist and air nozzles creates a sound which may be like that of CO 2  gas escaping from a beverage container being opened. The air flow through the mist nozzle also removes any residual water which might drip from the mist nozzle. Within the mist nozzle, the incoming water breaks up into small water droplets, mixes with the pressurized air to form even smaller droplets and discharges as a very fine mist. The air current issuing from the air nozzle entrains the mist and carries the mist toward the customer. The air flow which continues after the cessation of water flow eliminates water from the mist nozzle and ensures that all of the mist is conveyed toward the customer. 
     The present invention may also be employed in a larger installation such as a pavilion. As illustrated in FIG. 3, the pavilion 100, which is large enough to accommodate a gathering of people, may be simply formed of upright columns 112 spanned by an open-work roof of elevated members 114. The columns and/or the elevated members provide support for an array of mist nozzle assemblies 116 like those employed in the vending machine installation of FIGS. 1 and 2. The columns and elevated members may also carry graphics and display panels 118. Water and air conduits and control lines (not shown) for the mist nozzle assemblies and the display panels may be supported within or on the columns and elevated members. The water and air supplies and the controller may be suitably housed within the pavilion or at a remote location. As illustrated, the pavilion accommodates vending machines 120. 
     According to one operating scheme, the mist nozzle assemblies will periodically discharge to provide cooling refreshment to persons gathered in the pavilion. The graphics and the display panels can serve as constant reminders of the provider of the refreshing experience. 
     According to another operating scheme, the mist nozzle assemblies adjacent to the vending machines may discharge a cooling mist toward a customer making a purchase at one of the machines, as described above in connection with the vending machine installation of FIGS. 1 and 2. According to still another operating scheme, all of the mist nozzle assemblies will discharge a cooling mist when a purchase is made at one of the vending machines, to thus provide a strong inducement for purchasing products from the machines. 
     The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
