Description

BACKGROUND OF THE INVENTION

In many different industries, most notably, the airline catering industry, food products must be transferred from one area to another after preparation and before service. Food products after preparation are generally hot, for example, 170° F. The food products are then placed on trays which, in turn, are placed on a movable rack. The rack is then usually placed within a cabinet cooler, to reduce the temperature of.the food products to a desired temperature of, for example, 40° F. Thereafter, the rack can be removed from the cabinet cooler and moved into a conventional walk-in cooler for the final reduction in temperature of the food products to a temperature of, for example, 38° F. When the user is ready to process the food products, the rack is removed from the walk-in cooler for final processing of the food products by the user.

Problems have arisen, though, with the movement of the food products after preparation, to the walk-in cooler, and then to their final destination, i.e., airline carts. The food products will not maintain the desired temperature as they must be moved from place to place outside of a controlled environment of the desired temperature. Generally, the cabinet cooler is stationary and is connected to an intricate plumbing system, or requires the use of liquid nitrogen or liquid CO 2 . These cabinet coolers also generally require the user to push the rack onto a ramp in order to insert the rack within the cabinet cooler. Such a setup can cause safety problems.

Therefore, there is a need for an effective cabinet cooler that is portable such that it can move by itself, or in conjunction with a rack holding food products therein. There is also a need for an effective cabinet cooler that is capable of sealing cooled air therein when the rack is positioned therein. The present invention provides such a cabinet cooler. Other advantages of the present invention will become apparent upon reading the attached specification in combination with a study of the drawings.

OBJECTS AND SUMMARY OF THE INVENTION

A primary object of the invention is to provide a novel portable container system which is used for cooling of in-process food that is particularly applicable to the airline catering industry.

Another object of the invention is to provide a portable cabinet cooler that does not require a ramp for the rack to be rolled therein.

Yet another object of the.invention is to provide a cabinet cooler which uses dry ice, as opposed to liquid nitrogen or liquid CO 2 .

Still another object of the invention is to provide a cabinet cooler that requires no fixed plumbing, but only a 100v plug in.

Another object of the invention is to provide a cabinet cooler having elongated slots in a lower wall thereof to allow the legs of a rack to wheeled therein and to act as guides for the rack legs.

Yet another object of the present invention is to provide flexible seals along the length of the elongated slots which conform to the legs of the rack when the rack is positioned therein for sealing the bottom of the cabinet cooler.

Still another object of the present invention is to provide a cabinet cooler that is capable of rapidly cooling the inside thereof.

Another object of the present invention is to provide a cabinet cooler which allows a rack to roll directly into the cabinet cooler without any additional devices or modifications to the rack.

Yet another object of the present invention is to provide a cabinet cooler where the fans and driving means can be easily serviced and cleaned.

Another object of the present invention is to provide a cabinet cooler that can operate as either a cooler/freezer or, if desired, as an isothermal container to maintain the temperature within the cabinet cooler.

Briefly, and in accordance with the foregoing, the present invention provides a novel cabinet cooler. The cabinet cooler has an open housing defined by a lower wall, a rear wall, opposite side walls, and a top wall. The lower wall.has a plurality of wheels positioned on a bottom thereof so that the cabinet cooler can be easily moved.

The dry ice storage 80 is mounted within the upper chamber of the housing 24 by sliding the side edges of the ledge 88 along the respective upper slots 66 . A handle 89 may be provided on the front wall 84 of the dry ice storage 80 for convenience in inserting the dry ice storage 80 into the housing 24 and removing the dry ice storage 80 from the housing 24 .

The rack 22 that is used with the cabinet cooler 20 of the present invention is conventional and is illustrated in FIG. 2 . The rack 22 includes four vertical legs 90 , 92 , 94 , 96 , each of which has a wheel 98 mounted on a lower end thereof. A plurality of horizontal support members 10 a are provided between two of the legs 90 , 92 , and a plurality of horizontal support members 100 b are provided between the other two legs 94 , 96 . The respective horizontal support member 100 a , 100 b are aligned with each other and face each other. A lower diagonal bar 102 is provided between two of the legs 92 , 94 at a position spaced from the bottom ends of the legs 92 , 94 . A first upper diagonal bar 104 is provided between two of the legs 90 , 96 at a position spaced from the upper ends of the legs 90 , 96 . A second upper diagonal bar 106 is provided between the other two legs 92 , 94 at the upper ends of the legs 92 , 94 such that the first and second upper bars 104 , 106 cross over each other and form an X. Trays (not shown) can be removably mounted on the rack 22 by sliding the trays along the support members. 100 a , 100 b.

To place the rack 22 within the cabinet cooler 20 , the user opens the door 61 or parts the vinyls strips. Thereafter, the user rolls the rack 22 into the cabinet cooler 20 such that the legs 90 , 92 of the rack 22 enter into slot 50 within the bottom wall 26 and the other legs 94 , 96 of the rack 22 enter into slot 52 within the bottom wall 26 . The seals 56 , 58 within each slot 50 , 52 conform to the shape of the legs 90 , 92 , 94 , 96 to substantially prevent the leakage of air from within the cabinet cooler 20 to the outside. If desired, cutouts can be provided in the seals 56 , 58 to mold around the legs 90 , 92 , 94 , 96 . The door 61 is then closed or the vinyl strips are allowed to fall back into place. There is no need to modify the rack 22 or to use ramps to place the rack 22 within the cabinet cooler 20 .

If the thermopanel 70 is in the open position, that is, the thermopanel 70 is pulled away from the rear wall 32 of the housing 24 , air is circulated through the housing 24 by using the fans 46 . The fans 46 are driven to blow air toward the door 61 or the vinyl strips. The air flows over the trays (which have food products or the like thereon), from the back of the trays to the front of the trays and up the front of the housing 24 between the thermopanel 70 and the door 61 or the vinyl strips. The air then flows between the thermopanel 70 and the dry ice storage 80 . As the air flows between the thermopanel 70 and the dry ice storage 80 , the air is cooled by the dry ice contained within the dry ice storage 80 . The air then flows between the partition 38 and the rear wall 32 for recirculation through the housing 24 . The fans 46 suck the air from between the thermopanel 70 and the dry ice storage 80 .

If the thermopanel 70 is in the closed position, that is, the thermopanel 70 abuts against the rear wall 32 of the housing 24 such that the space between the partition 38 and the rear wall 32 is closed, the air is not circulated through the housing 24 . Instead, the cabinet cooler 20 acts as an isothermal container to maintain the temperature of the food products or the like on the trays. Coldness from the dry ice passes through the thermopanel 70 to the food products or the like in the lower chamber.

To remove the rack 22 from the cabinet cooler 20 , the user opens the door 61 or parts the vinyls strips. Thereafter, the user rolls the rack 22 out of the cabinet cooler 20 . The door 61 is then closed or the vinyl strips are allowed to fall back into place. There is no need to modify the rack 22 or to use ramps to remove the rack 22 from the cabinet cooler 20 .

Attention is now invited to the second embodiment of the cabinet cooler 220 shown in FIGS. 6-8 . The cabinet cooler 220 includes a housing 224 which is formed from a lower wall 226 , opposite side walls 228 , 230 extending upwardly from side edges of the lower wall 226 , a rear wall 232 extending upwardly from a rear edge of the lower wall 226 , and a top wall 234 which is connected to the upper ends of the side walls 228 , 230 and the rear wall 232 . The walls 226 , 228 , 230 , 232 , 234 are made of a suitable material, such as fiberglass reinforced plastic composite material, or polyethylene.

The fans 246 are driven by suitable means, such as a 110V AC current battery.

Each fan housing 237 has a bottom wall 241 , opposite side walls 243 , 245 which extend upwardly and outwardly from side edges of the bottom wall 241 and a front wall 247 which extends upwardly from a front edge of the bottom wall 241 and is connected to front edges of the side walls 243 , 245 . As such, the upper end of the fan housing 237 is open. The bottom wall 241 and the side walls 243 , 245 extend from the rear wall 232 of the housing 224 into the cavity within the housing 224 formed by the walls 226 , 228 , 230 , 232 , 234 . The front wall 247 is parallel to the rear wall 232 and is generally V-shaped as the opposite side walls 243 , 245 extend upwardly and outwardly from side edges of the bottom wall 241 . The aperture 239 of the fan housing 237 is provided through the front wall 247 of the fan housing 237 . The fan housing 237 is made of a suitable material, such as fiberglass reinforced plastic composite material, or polyethylene.

A tray 249 can be positioned on top of each fan housing 237 . The trays 249 span the width of the rear wall 232 such that the trays 249 extend between sidewalls 228 , 230 . The trays 249 also extend from the rear wall 232 to the front wall 247 of the fan housing 237 . Supports 251 can be mounted to each of the side walls 228 , 230 to support the ends of the tray 249 while the side walls 243 , 245 and front wall 247 of the fan housing 237 support the middle of the trays 249 .

A bottom wall 253 of the tray 249 has an opening therein that is in communication with the open upper end of the fan housing 237 . A mesh screen 255 is mounted within the opening of the bottom wall 253 and defines a plurality of perforations through the bottom wall 253 . The mesh screen 255 is formed from a suitable material, such as expanded metal. The bottom wall 253 of the tray 249 is used to support at least one dry ice cell 263 , which can be a dry ice slab or dry ice pellets. The tray 249 can be removed from the housing 224 such that a user does not have to directly handle the dry ice cell 263 . The tray 249 can further include front, side and rear walls if desired.

The bottom wall 226 of the cabinet cooler 220 includes two elongated slots 250 , 252 which extend from the front of the bottom wall 226 to a position which is spaced from the rear wall 232 of the housing 224 . An elongated frame 254 which matches the shape of each slot 250 , 252 is provided in each slot 250 , 252 . The frame 254 can be snapped into or seated in each slot 250 , 252 . A flexible seal 256 , 258 is mounted on the frame 254 . The seal 256 , 258 is formed from two strips of vinyl which overlap each other such that an elongated slit 260 is formed along the length of the seal 256 , 258 . Each frame 254 and its associated seal 256 , 258 is removable from the bottom wall 226 so that each frame 254 and seal 256 , 258 can be cleaned.

A door 261 can be hingedly connected to one of the side walls 228 and can be swung around the hinges 262 to close the front of the housing 224 . The other side wall 230 can have latches 264 which connect with catches (not shown) on the free end of the door 261 when the door 261 is closed to secure the door 261 in a closed position. Alternatively, the door 261 and its associated hardware, can be eliminated and vinyl strips (not shown) can be attached to the top wall 234 and hang downwardly therefrom to cover the open front of the housing 224 .

The rack 22 that is used with the cabinet cooler 220 of the second embodiment of the present invention is conventional and is exactly the same as that used with the cabinet cooler 20 of the first embodiment of the present invention. Therefore, the description of the rack 22 is not repeated.

Prior to the insertion of the rack 22 into the cabinet cooler 220 , slabs of dry ice 263 are placed on the trays 249 . The trays 249 are slid into the housing 224 and are seated on the supports 251 and on top of the fan housing 237 . To place the rack 22 within the cabinet cooler 220 , the user opens the door 261 or parts the vinyl strips. Thereafter, the user rolls the rack 22 into the cabinet cooler 220 such that the legs 90 , 92 of the rack 22 enter into slot 250 within the bottom wall 226 and the other legs 94 , 96 of the rack 22 enter into slot 252 within the bottom wall 226 . The seals 256 , 258 within each slot 250 , 252 conform to the shape of the legs 90 , 92 , 94 , 96 to substantially prevent the leakage of air from within the cabinet cooler 220 to the outside. If desired, cutouts can be provided in the vinyl strips to mold around the legs 90 , 92 , 94 , 96 . The door 261 is then closed or the vinyl strips are allowed to fall back into place. The rack 22 does not contact the fan housings 237 or trays 249 because the slots 250 , 252 of the lower wall 226 do not extend far enough into the housing 224 . There is no need to modify the rack 22 or to use ramps to place the rack 22 within the cabinet cooler 220 .

After the insertion of the rack 22 into the cabinet cooler 220 , the cool air that is emitted from the respective slabs of dry ice 263 is sucked through the perforations defined by the mesh screen 255 of the tray 249 and into the fan housing 237 by the fans 246 . This cools the air. The V-shaped side walls 243 , 245 of the fan housing 237 help draw cold air down to the fans 246 . The fans 246 are driven to blow cooled air toward the door 261 or the vinyl strips. The air flows over the trays (which have food products or the like thereon), from the back of the trays to the front of the trays and up the front of the housing and back over the dry ice 263 . The air continues to recirculate through the housing 224 , over the dry ice 263 , into the fan housing 237 , and back out over the trays of food.

To remove the rack 22 from the cabinet cooler 220 , the user opens the door 261 or parts the vinyl strips. Thereafter, the user rolls the rack 22 out of the cabinet cooler 220 . The door 261 is then closed or the vinyl strips are allowed to fall back into place. There is no need to modify the rack 22 or to use ramps to remove the rack 22 from the cabinet cooler 220 .

A suitable usage of both of the embodiments of the present invention is as follows. The rack 22 which has trays with food products or the like thereon is wheeled into the cabinet cooler 20 , 220 of the present invention. The food products or the like are hot, having a temperature of, for example, 170° F., prior to insertion into the cabinet cooler 20 , 220 of the present invention. The cabinet cooler 20 , 220 is used to reduce the temperature of the food products or the like to a desired temperature of, for example, 40° F. Thereafter, the rack 22 is removed from the cabinet cooler 20 , 220 and moved into a conventional walk-in cooler (not shown) for the final reduction in temperature of the food products or the like to a temperature of, for example, 38° F. When the user is ready to process the food products or the like, the rack 22 is removed from the walk-in cooler for final processing of the food products or the like by the user.

After final processing, the rack 22 can be reinserted into the cabinet cooler 20 , 220 and the cabinet cooler 20 , 220 and the rack 22 can be directly wheeled to the airline carts. The rack 22 and the trays or just the trays can then be removed from the cabinet cooler 20 , 220 for transferring the trays to the airline cart.

The cabinet cooler 20 , 220 of the present invention can also be used as a thermal box. The empty rack 22 can be placed within the cabinet cooler 20 , 220 . Trays with food products or the like are then mounted onto the support members 100 a , 100 b while the rack 22 is within the cabinet cooler 20 , 220 . Preferably, for this type of application, vinyl strips are used to close the front of the housing 24 , 224 so that the user does not have to constantly open and close the door 61 , 261 .

The cabinet cooler 20 , 220 of the present invention is used to prevent the temperature of the food products or the like from rising during the time the trays are being prepared and can be used to remove heat from the food products or the like in an efficient manner. In addition, the cabinet cooler 20 , 220 of the present invention is not intended to freeze the food products or the like. Usage of the cabinet cooler 20 , 220 of the present invention as an intermediate step also reduces condensation within the walk-in cooler and reduces the amount of dehydration of the food products or the like.

The cabinet cooler 20 , 220 of the present invention does not require a carbon dioxide tank, does not require a nitrogen tank and does not require plumbing which would be associated with these tanks or any other mechanical apparatus using cooling or freezing. In addition, the cabinet cooler 20 , 220 of the present invention is portable making the cabinet cooler very convenient to use.

While preferred embodiments of the present invention are shown and described, it is envisioned that those skilled in the art may devise various modifications without departing from the spirit and scope of the foregoing description.
