Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims the benefit of U.S. Provisional Application Serial No. 60/355,503, filed Feb. 11, 2002.[0001]

BACKGROUND

The present invention relates to refrigerated merchandisers for storing and vending packaged products; and more particularly, to ice merchandisers for vending bags of ice, having a novel positioning of a compressor assembly for improved capacity, efficiency and/or cleanliness of the merchandiser.

Ice merchandiser units are essentially refrigerated cabinets, with at least one door providing access to the cabinet, that store and vend bagged ice inside or outside of grocery stores, convenient shops, gas stations and the like. The interior ice merchandisers typically include at least one glass door while the exterior merchandisers typically include insulated doors.

Many conventional ice merchandiser units position their compressor assemblies of their freezer units at the bottom of the ice merchandiser. Such compressor assemblies are typically enclosed from the interior of the ice merchandiser housing by insulated walls and are typically ventilated by positioning a ventilated panel on the front wall of the ice merchandiser unit over an opening that communicates with the compressor assembly enclosure. This configuration may be disadvantageous in certain situations. For example, as will be appreciated by those of ordinary skill in the art, such compressor assemblies tend to give off significant amounts of heat, which tends to rise and potentially damaging to the contents of the ice merchandiser unit. To counter the affect of the heat rising from the compressor assembly and into the ice bags stored in the ice merchandiser unit interior, the compressor assemblies in such conventional ice merchandisers are heavily insulated, decreasing the capacity of the ice merchandiser interior. Furthermore, because the ventilation panel is positioned close to the ground at the front of the ice merchandiser unit, it tends to collect a significant amount of dirt and other debris kicked up by foot traffic, for example, in front of the ice merchandiser unit.

Additionally, some conventional ice merchandiser units position their compressor assemblies on the top wall of the unit's housing that defines the interior in which the bags of ice are stored, where the compressor assembly is covered by a false top or a shell. As such the added height of the unit provided by this positioning of the compressor assembly may reduce the vertical space left for the unit's storage capacity.

SUMMARY

The present invention provides an ice merchandiser, or a packaged product merchandiser, including a shelf area or enclosure positioned at a top-rear corner of the merchandiser housing or along a top portion (such as the top-center) of the merchandiser housing for enclosing the compressor assembly therein. Because the compressor assembly is thus placed at the level of the merchandiser's evaporators, the compressor assembly is positioned within the merchandiser assembly in a space that is typically unused, thereby increasing the capacity of the ice merchandiser. Furthermore, because the heat rising from the compressor assembly will not rise into the packaged products stored within the merchandiser, the amount of insulation provided around the compressor assembly enclosure may be decreased, thereby, further increasing the capacity of the ice merchandiser. Likewise, because heat from the compressor assembly will not tend to rise into the refrigerated/frozen product, the efficiency of the merchandiser unit may also be increased. Finally, because the ventilation panels for the compressor assemblies are positioned well above the ground, the compressor assemblies will tend to stay much cleaner.

Accordingly, it is the first aspect of the present invention to provide a packaged product merchandiser for merchandising frozen or refrigerated packaged products that includes: (a) a housing in which a multitude of packaged products are to be stored having at least one door on the front wall thereof; (b) a cooling unit including a compressor assembly; (c) an elevated shelf mounted within the housing perimeter formed by the front, rear, top and side walls, approximate the top wall of the housing, where the elevated shelf seats the compressor assembly, and where the elevated shelf and compressor assembly are substantially closed-off with respect to the interior of the housing; and (d) at least two ventilation panels, where each ventilation panel is installed on a respective one of the front, rear, top and side walls over a corresponding opening to the closed-off compressor assembly. In a more detailed embodiment, the shelf and compressor assembly are positioned at a top-rear corner of the housing substantially at an intersection of the top, rear and one of the side walls.

DETAILED DESCRIPTION

As shown in FIGS. 1 and 2, an exemplary embodiment of an [0022] indoor ice merchandiser 10 according to the present invention includes a housing having a front wall 12, a top wall 14, a left side wall 16, a right side wall 18, a rear wall 20 and a bottom (not shown). The front wall 12 includes a pair of glass doors 22 providing access to the interior of the housing so that ice bags can be stocked by suppliers and removed by customers. The walls of the housing are typically insulated.
Referring specifically to FIG. 2, the left rear corner of the housing (at the intersection of the [0023] top wall 14, rear wall 20 and left side wall 16) includes a collapsed portion 24 forming a shelf 26 for seating the compressor assembly 28 thereon. A top ventilation panel 30, a rear ventilation panel 32 and a side ventilation panel 34 are mounted flush with the respective top, rear and side walls over the collapsed portion 24 and shelf 26 to provide a ventilated covering for the compressor assembly 28. The collapsed portion includes side walls 36, 38 closing off the shelf 26 from the interior of the housing, where the vertical side walls may also include ports for communicating the compressor assembly 28 with the internal evaporator 40 and/or with power sources and the like.
By positioning the compressor assembly within the rear top corner of the ice merchandiser housing as in the first exemplary embodiment, the compressor assembly fills a formerly unused space adjacent to the [0024] evaporator 40 allowing for greater effective use of the merchandiser interior, thereby increasing the capacity of the merchandiser. Additionally, because the compressor assembly is positioned above the frozen merchandise, heat will not tend to rise from the compressor assembly into the frozen merchandise. This may increase the efficiency of the ice merchandiser and may also decrease the thickness of the insulation provided between the compressor assembly and the interior of the merchandiser housing, which could also increase the capacity of the ice merchandiser. Additionally, because the compressor assembly is now located above the floor, away from traffic, it potentially will not collect dirt as quickly as prior art compressor assemblies located near the floor.
While the compressor assembly of the first exemplary embodiment is positioned at the left rear corner of the housing, it is, of course, within the scope of the present invention to locate the compressor assembly of the first exemplary embodiment at the right rear corner of the housing. Furthermore, while the [0025] ventilation panels 30, 32 and 34 are shown as individual panels, it is within the scope of the invention that the panels can be coupled together to form a pyramidal ventilation panel or, alternatively, be integrated into the respective walls themselves.
As shown in FIGS. 3A, 3B and [0026] 4, a second embodiment of the present invention is an outdoor ice merchandiser 42 having a merchandiser housing with a top wall 44, back wall 45, a left side wall 46, a right side wall (not shown), a lower front wall 48, an upper-angled front wall 50, and a bottom (not shown). These walls are typically insulated. The upper-angled front wall 50 includes a pair of openings accessible by insulated doors 52, 54. The doors 52, 54 provide access to the interior of the ice merchandiser 42 so that suppliers can supply bagged ice to the merchandiser and customers can retrieve bags of ice from the merchandiser. An enclosed shelf 56 is positioned between each of the doors 52, 54 and extends from the upper-angled wall 50 of the ice merchandiser back to the rear wall 45 of the ice merchandiser. (See FIG. 4) This enclosed shelf 56 houses a compressor assembly 58 therein and has a vertical height slightly larger than the height of the compressor assembly 58 so as to maximize capacity of the ice merchandiser interior.
The [0027] enclosure 59 formed by the enclosed shelf 56 and side walls 64 and 66 includes a top that is flush with the top wall 44 of the housing. The front of the enclosure 59 is flush with the upper-angled front wall 50 of the housing, and the rear of the enclosure 59 is flush with the rear wall 45 of the ice merchandiser housing. Referring to FIGS. 3A and 3B, the front of the enclosure 59 is covered by a ventilated panel 60 and the rear of the enclosure 59 is also covered by a ventilated panel 62. The ventilated panels 60, 62 provide ventilation for the compressor assembly 58 with the ambient environment. Preferably the side walls 64 and 66 and the shelf 56 of the enclosure 59 are insulated.
Referring again in FIG. 4, the [0028] elevated compressor assembly 58 is positioned on the enclosed shelf 56 between the pair of evaporators 68, 70 thereby filling unused space between the evaporators and maximizing the capacity of the ice merchandiser for bags of ice. Furthermore, by positioning the compressor assembly above the frozen product, the heat tending to rise from the compressor assembly 58 will not rise into the frozen product stored within the merchandiser, thereby increasing the efficiency of the ice merchandiser and decreasing the amount of insulation needed between the compressor assembly and the interior of the ice merchandiser housing. Finally, because the ice merchandiser is positioned above the ground level, it will be less susceptible to the intake of dirt and other debris.
