Description




BACKGROUND OF THE INVENTION




The present invention relates generally to a product display unit, and more particularly to a counter top merchandiser for holding and displaying both hot and cold products.




One such application for this invention is the storage and display of hot and cold food products. However, it is contemplated that other types of hot and cold products may be stored and displayed in the merchandiser. This invention is particularly related to the technology disclosed in U.S. Pat. No. 6,257,010 entitled “Merchandiser for Warm and Cold Food”, issued Jul. 10, 2001, owned by Duke Manufacturing Co. of St. Louis, Mo., and incorporated herein by reference for all purposes. The merchandiser disclosed in this patent is described as being adapted to rest on a counter with its upper compartment elevated somewhat above the counter top and its lower compartment recessed into the counter, i.e., positioned in an opening cut in the counter top to receive the cold pan of the device. Cutting such an opening increases the cost of installation. Further, in the event the merchandiser is later removed, the counter top must be replaced or repaired to cover the opening. Therefore, there is a need for a counter top merchandiser which can be installed without requiring an opening in the counter top.




SUMMARY OF THE INVENTION




Among the several objects of this invention may be noted the provision of a hot/cold product merchandiser which can be installed on a counter top without cutting a hole in the counter top; the provision of such a merchandiser which is easy to install on a counter top and to remove from the counter top; the provision of such a merchandiser which displays products in the merchandiser in a way which is pleasing to customers; the provision of such a merchandiser which is attractive in appearance and which is easy to use; the provision of such a merchandiser which has a product display section and a product storage section from which products can be removed as they are sold without disturbing the products in the display section; the provision of such a merchandiser which, in a preferred embodiment, has a front which is permanently closed to deny customers access to the merchandiser but which is transparent to permit viewing of the product in the merchandiser; the provision of such a merchandiser which, in a preferred embodiment, allows independent access to the cold compartment from both sides of the merchandiser; and the provision of such a merchandiser which has a warm compartment for storing warm products and a cold compartment for storing cold products.




In general, a counter top merchandiser of the present invention comprises a warm compartment within the merchandiser for holding and displaying warm products. A cold compartment is below the warm compartment and defined in part by a bottom wall positioned above the counter top when the merchandiser is placed on the counter top. The cold compartment has a display section and a storage section. A partition separates the warm and cold compartments. A heating unit heats products within the warm compartment and a refrigeration unit cools products within the cold compartment. At least one transparent wall allows viewing of products within the merchandiser. Openings provide access to the warm and cold compartments from the rear of the merchandiser.




The present invention is also directed to a method of using such a merchandiser. The method includes the steps of placing cold products to be viewed in the display section and placing cold products to be removed for customer use in the storage section. Warm products to be viewed and stored are placed in the warm compartment. The refrigeration unit is operated to cool products in the cold compartment and the heating unit is operated to heat products in the warm compartment.




Other objects and features of the present invention will be in part apparent and in part pointed out hereinafter.

DESCRIPTION OF THE PREFERRED EMBODIMENT




Referring now to the drawings, and more particularly to

FIGS. 1-5

, a hot/cold counter top merchandiser of the present invention is designated in its entirety by the reference numeral


1


. As shown in

FIGS. 1-3

, the merchandiser


1


is adapted to be mounted on a counter top, designated


3


, without having to cut an opening in the counter top, or otherwise damaging the counter top, so that if and when the merchandiser is removed, the counter top can be used without being replaced or repaired.




As shown best in

FIG. 5

, the merchandiser


1


has an upper warm compartment


5


for holding and displaying warm products and a lower cold compartment


7


for holding and displaying cold products. In accordance with one aspect of the present invention, the cold compartment


7


has a front display section


9


for displaying products to prospective customers, and a rear storage section


11


for storing products to be sold or otherwise distributed. The products in the warm compartment


5


are heated by a heating unit, generally designated


13


. The products in the cold compartment are cooled by a refrigeration unit, generally designated


15


. A partition


25


separates the warm compartment


5


from the cold compartment


7


. In one embodiment (FIG.


7


), the partition


25


comprises a layer of fiberglass insulation


27


and a layer of foam insulation


29


disposed between a top stainless steel panel


31


and a lower sheet metal panel


33


.




In one embodiment, the cold compartment


7


is defined by a cabinet of sheet metal


41


(e.g., galvanized steel) and by the partition


25


which is affixed to the cabinet. The cabinet


41


has a bottom wall


43


, opposite side walls


45


, and a front wall


47


which includes upper and lower panels,


49


and


51


respectively, mounted in openings in the front wall. The upper panel


49


is preferably transparent, forming a window


61


to allow viewing of products in the display section


9


of the cold compartment


7


. The window


61


may be constructed of dual pane thermal glass, although other types of windows are contemplated by this invention (e.g., single pane glass). A thermal mastic seal


63


around the periphery of the window


61


seals against the front wall


47


of the cabinet


41


to prevent the escape of cold air from the cold compartment


7


. The window


61


is preferably immovably mounted in the front wall


47


to prevent access to the cold compartment


7


from the front of the merchandiser


1


. Optionally, the front wall


47


of the merchandiser


1


may be modified to allow access to the warm and/or cold compartments,


5


and


7


respectively, from the front of the merchandiser


1


. A housing


65


is provided at the front of the cabinet


41


behind the lower panel


51


of the front wall


47


for housing the refrigeration unit


15


. The front wall


47


of the cabinet is preferably inclined, sloping downward and forward at an angle of about 15°, although this angle may vary, preferably within a range of 5° to 25°. The use of an inclined front wall


47


in the preferred embodiment, achieves a more attractive presentation of the products within the merchandiser


1


. It will be understood that the side walls


45


and the lower panel


51


form preferred locations for advertising panels (not shown) to promote products held within the merchandiser, but other locations on the merchandiser for mounting product advertisements are also contemplated (i.e., outer surface


209


).




The bottom and side walls,


43


and


45


respectively, of the cabinet


41


and housing


65


for the refrigeration unit


15


are lined with a suitable thermal insulation


67


, as shown in FIG.


5


. This insulation may be a foam insulation, for example, sandwiched between the walls and an interior liner of stainless steel sheet metal


69


, for example. A frame of insulating material


71


(e.g., PVC channel) around the cold compartment


7


at the back of the cabinet


41


provides a thermal break between the inner liner


69


and outer cabinet


41


. The insulating frame


71


is secured in place by suitable means, such as snap clips


73


(FIG.


7


). The back wall


81


of the cabinet


41


is defined, at least in part, by a pair of door panels


83


mounted on a vertical mullion bar


85


extending between the partition


25


and the bottom wall


43


of the cabinet. In the embodiment of

FIG. 5

, the back wall


81


is shown substantially perpendicular to the counter top, but it will be understood that the back wall could also be inclined towards the front of the merchandiser or otherwise configured without departing from the scope of this invention. The mullion bar


85


is preferably located generally midway between the side walls


45


of the cabinet


41


to define left and right openings of about equal area. The doors


83


are mounted on the mullion bar


85


by common top and bottom hinges,


91


and


93


respectively, that allow independent operation of each door. Rubber seals


97


mounted on the doors


83


seal against the cabinet


41


around respective openings. The doors


83


are retained in a closed position by magnets


99


(FIG.


7


). It will be understood that other variations of the merchandiser


1


are contemplated that include a back wall


81


having any number of doors


83


including one or more than two. Also, a back wall


81


providing only limited access to the cold compartment


7


, or that prevents access altogether, is contemplated. Further, the mullion bar


85


could be offset resulting in corresponding left and right doors


83


of unequal size.




In the embodiment shown in

FIG. 5

, the display section


9


and storage section


11


of the cold compartment


7


are separated by a divider


121


spaced back from and generally parallel to the transparent window


61


of the front wall


47


of cabinet


41


. The divider


121


is preferably located above the housing


65


for the refrigeration unit


15


, but it could also be located above the rear horizontal portion


123


of the liner


69


. The divider


121


can be a partition of any suitable type, such as a grate, a vacuum formed panel having pockets for holding items to be displayed, a transparent wall, or an opaque wall. The display section


9


of the cold compartment


7


comprises the volume of space between the divider


121


and the window


61


at the front of the merchandiser


1


. The storage section


11


of the cold compartment


7


comprises the volume of space between the divider


121


and the back wall


81


of the cabinet


41


. The volume of the storage section


11


of the illustrated embodiment is approximately 5.0 cu. ft. and the volume of the display section


9


is approximately 0.4 cu. ft. Alternatively, the divider


121


could be omitted from the cold compartment


7


, in which event the display section


9


would comprise the entire volume above the refrigeration housing


65


. The storage section


11


preferably has a volume in the range of 100% to 1200% larger than the volume of the display section


9


, more preferably 600% to 1500% larger, still more preferably 1000% to 1500% larger, and most preferably about 1100% to 1200% larger. Racks (not shown) are preferably used to store products in an organized fashion in the storage section


11


. For example, three horizontal storage racks or shelves, vertically arranged, can be used. One or more racks or shelves (not shown) can also be installed in the display section


9


for displaying products in an attractive manner. One or more fluorescent lamps (not shown) may be attached to the bottom of the partition


25


to provide lighting for the storage section


11


and display section


9


.





FIG. 8

schematically illustrates the refrigeration unit


15


. As shown, the unit comprises a conventional refrigeration circuit


129


including a compressor


131


, a condenser


133


, a condenser fan


135


, a heat exchanger


137


, an evaporator


139


, an evaporator fan


141


and capillary tube


143


. The unit is controlled by means of an on/off switch


151


located at the back of the merchandiser (FIG.


3


). Louvers


153


in the side walls


45


of the cabinet


41


allow for the entry of ambient air into the refrigeration unit


15


. Air from within the cold compartment


7


is circulated into the refrigeration unit


15


through one or more return openings


145


and passes over the evaporator coil


137


and is cooled. The colder air is then discharged from the refrigeration system


15


through one or more discharge openings


147


back into the cold compartment


7


. A drip pan


161


for condensate is located directly below the refrigeration unit


15


and is removable from the merchandiser


1


. The lower panel


51


at the front of the cabinet


41


is preferably removable to provide access to the refrigeration unit


15


. For the sake of appearance and sanitation, a gasket


171


is provided around the bottom of the cabinet to close the gap between the cabinet and the counter top, thereby preventing debris from becoming trapped below the cabinet.




Referring to

FIGS. 1-5

, the warm compartment


5


of the merchandiser


1


is defined, in part, by a pair of risers


201


extending up from the side walls


45


of the cabinet


41


adjacent the rear of the cabinet. The risers


201


of the preferred embodiment are made from sheet metal but it will be understood that other materials (i.e., composites or ceramics) can be used. Each riser


201


is secured to the cold compartment cabinet


41


by conventional fasteners (e.g., rivets, not shown) and has a flange


203


along its front vertical edge


205


projecting forward in a plane which is offset inward from the plane of the outer surface


209


of the riser (FIG.


5


). A housing


221


for the heating unit


13


is attached to the risers


201


by screws


223


or the like in a position spaced above the horizontal partition


25


. The housing


221


has top and back walls,


225


and


227


respectively, that further define the warm compartment


5


. As will be described later in more detail, the heating unit


13


is similar to that disclosed in U.S. Pat. No. 6,257,010 and functions to circulate warm air throughout the warm compartment


5


. One or more incandescent lamps (not shown) are attached to one or both of the risers


201


inside the warm compartment


5


to illuminate products within the warm compartment for viewing.




In one embodiment, the warm compartment


5


is further defined by a pair of side panels


235


which are secured to respective flanges


203


of the risers


201


by suitable fasteners


237


(e.g., screws) and which extend forward from the risers to the front of the merchandiser


1


. The thickness of the side panels


235


generally corresponds to the inward offset of the flanges


203


so that, when assembled, the outer surfaces


209


of each riser


201


and respective side panel are generally coplanar to enhance attractiveness and to provide smooth joints. The side panels


235


are bridged by a cover panel


241


which extends over the warm compartment


5


. Preferably, the side panels


235


and cover panel


241


are transparent to allow viewing of products within the warm compartment


5


. In the illustrated embodiment these panels


235


and


241


are fabricated as a single piece of molded plastic (e.g., acrylic) but it will be understood that other materials (i.e., glass) and constructions can be used. The cover panel


241


is preferably formed to have a substantially horizontal rear portion


243


which is generally coplanar with the top of the heater housing


225


, an inclined generally planar front portion


245


defining the front of the warm compartment


5


, and a curved portion


247


joining the front and rear portions. In the illustrated embodiment the curved portion


247


of the cover panel has a radius of curvature of about 8 inches, but it will be understood that this radius may vary. In the preferred embodiment, the inclined front portion


245


of the cover panel


241


is substantially coplanar with the front wall


47


of the cabinet


41


defining the cold compartment


7


. Access to the warm compartment


5


is provided by a door


255


closing an opening


257


at the back of the merchandiser


1


between the heater housing


221


and the partition


25


. When closed, the door


255


defines the back of the warm compartment


5


(FIG.


5


). In one embodiment, the door


255


is mounted for pivoting about a generally horizontal axis between open and closed positions by a pair of hinges


261


attached to the heater housing


221


. When closed, the door


255


seals against a rubber seal


267


secured to the partition


25


and to the risers


201


. A handle


269


is provided for swinging the door


255


open and closed.





FIG. 6

illustrates the preferred heating unit


13


which, as previously noted, may be similar to that disclosed in U.S. Pat. No. 6,257,010. The unit


13


is disposed in the housing


221


and includes a horizontal mounting plate


281


affixed by screws


283


or other suitable means to the housing


221


. A heating element


287


is secured, as by wire clips


289


, to the mounting plate


281


in a position below the plate. Electric current is provided to a terminal


293


of the heating element


287


via wiring (not shown) entering the housing


221


through an annular bushing


295


in one wall of the housing. A layer of thermal insulation


301


is provided above the mounting plate


281


. The unit also includes a motor


303


driving an upper fan


305


above the mounting plate


281


and a lower fan


307


below the heating element


287


, the lower fan being rotatable to circulate air from the warm compartment


5


over the heating element and to discharge the heated air back into the warm compartment, and the upper fan being rotatable for cooling the motor. The motor


303


is preferably a single-speed dc motor. The electric heating element


287


and lower fan


307


are enclosed by a cover


315


removably secured to the housing


221


by suitable fasteners


317


, and by a mesh guard screen


319


over an opening


321


in the cover around the lower fan


307


. The cover


315


and mounting plate


281


combine to define an air plenum


335


. The lower fan


307


forces air out of the plenum


335


through the lower guard screen


319


and slots


337


in the bottom of the lower cover


315


creating a slight negative pressure in the plenum. The negative pressure created by the lower fan


307


pulls air into the plenum


335


through gaps


339


in the cover. The air entering the plenum


335


flows across the heating coil


287


and exits the plenum through the cover


315


and guard screen


319


. The heating unit


13


is controlled via a thermostat control knob


345


located at the back of the merchandiser


1


(FIG.
