Patent Application
20050205081
The present invention relates in general to a heated food cabinet and more particularly, but not limited to, a heated food cabinet that includes a moveable food drawer that has a positional drawer door.
Food warming devices, are often used in commercial establishments for maintaining prepared foods at a serving temperature. These cabinets are also used to reheat food products and for storage of food products that require extensive preparation time.
These food warming cabinets include one or more drawers that are positional within a heated cavity. The drawers include a storage area for the food that may be either a permanent part of the drawer or a removable tray or pan. In either situation the food product must be placed in and removed from the storage area, and the storage area must be regularly sanitized.
In the prior art devices having a permanent food storage container as part of the drawer increases the effort and time required to clean and sanitize the food storage area. First, it is necessary to shut down the heating element for safety reasons resulting in taking the food cabinet out of service, not only for the cleaning process but also during the period of time for the heating cavity to cool and then for the period of time for the heating cavity to again attain the desired temperature. Further, to achieve adequate cleaning the entire drawer must be removed from the food cabinet wasting time and often resulting in damage to the drawer and/or the food cabinet.
Some prior art food warming cabinets include drawers that have a removable food storage container. These devices allow a user to exchange food containers within the drawer and permit easier cleaning of the food container. However, these prior art devices require that a user precariously grip the food container when placing the container into the drawer or removing the container from the drawer. The limited access and ability to grip the food container is due to the required minimal foot print of the food cabinet and the utilization of a minimal heated cavity. This limited ability to handle the food container often results in accidents wherein the food container is dropped or mishandled resulting in injury to the user or others in the vicinity, damage to the food cabinet, and loss of food product.
It is thus a desire of the present invention to provide a positional drawer door for a food cabinet that address shortcomings of the prior art food cabinets. It is a still further desire of the present invention to provide a positional drawer that facilitates access to a drawer food container without sacrificing size limitations or the capacity of the food cabinet. It is a still further desire of the present invention to provide a positional drawer door that facilitates quick access for removing or placing a food container in a food cabinet limiting the loss of heat from the heated cavity, conserving energy, and preventing unnecessary heating of the heat source that may overcook the contained food product.
In view of the foregoing and other considerations, the present invention relates to food warming cabinets and more particularly a positional drawer door for a food cabinet.
It is a benefit of the present invention to provide positional drawer door that is movable between an open position to a closed and locked position.
It is a further benefit of the present invention to provide a positional drawer door that facilitates full access to a food tray for inserting the food tray into the drawer or removing the food tray from the drawer.
Accordingly, a positional drawer door for a food warming oven is provided. The positional drawer door is connected to the side rails of a drawer frame in a manner to be moved from a closed position to an open position. The drawer frame may be adapted to removably carry a food tray. The positional drawer door is selectively maintained in the closed position by a locking mechanism connectable between the positional door and the side rails of the drawer frame.
A food warmer oven is further provided, the food warmer oven includes a cabinet having opposing side walls, a top wall, a bottom wall, a back wall, and a front wall defining a heating cavity, the front wall defining an opening into the heating cavity; a heating source disposed within the heating cavity; a drawer frame having a pair of opposing side rails, each of the side rails having a front end and a terminal end, the side rails being functionally connected with the side walls of the cabinet in a manner such that the drawer frame can be moved between an open position wherein the drawer frame extends substantially exterior of the heating cavity through the opening and a closed position wherein the drawer frame is positioned substantially within the heating cavity, the front end of the side rails being positioned proximate the front wall and the terminal end being positioned proximate the back wall when the drawer frame is in the closed position; a food tray removably held by the drawer frame; a door moveably connected to the side rails of the drawer frame, the door moveable between an open position and a closed position; and a locking mechanism in connection between the door and the side rails of the drawer frame for selectively maintaining the door in the closed position.
