Benefits of technology

The patent describes a heating and cooling system for a mobile food carrying cart. The system includes a shelf and thermoelectric devices that are connected to the shelf. The cart also has a support structure and one or more thermoelectric devices that are connected to the shelf. The system can control the temperature of the food products and can be powered by a variety of energy sources. The technical effects of this invention include improved food preservation and control over food temperature during transportation.

Problems solved by technology

Vapor compression based cooling systems cool all of the food products in a given cart to a fixed set temperature, which can preclude the transport of more than one food type.
In addition, vapor compression based cooling systems have high noise, high vibration and a considerable weight, all affecting the mobility of the cart.

Embodiment Construction

[0017]Referring now to FIG. 1, an exemplary embodiment of a mobile food carrying cart generally referred to by reference numeral 10 is illustrated. Cart 10 may heat, cool, and provide temperature control storage at a desired temperature for a plurality of food products, such as frozen food, fresh food, or wine for uses such as commercial or military applications. However, the present disclosure contemplates the storage and refrigeration of other such food and non-food items.

[0018]The products are stored on a plurality of shelves 30. The size, shape and number of shelves 30, as well as their configuration in cart 10, can vary with the particular needs of cart 10. Such factors as sizing, mobility, refrigeration needs, heating needs, container capacity, and others can be used by one of ordinary skill in the art to determine the particular size, shape and number of shelves 30, as well as their configuration in cart 10. In the exemplary embodiment, each of the shelves 30 has a planar, re...

Abstract

A heating and cooling system is connected to a mobile food carrying cart comprising at least one shelf and one or more thermoelectric devices.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates generally to mobile food carrying carts and, more particularly, a method and apparatus for heating and cooling a mobile food carrying cart.[0003]2. Description of the Related Art[0004]Mobile food carrying carts are used to store and ship food products to different locations at a desired temperature. In contemporary mobile food carrying carts, chilled air is circulated about the interior of the cart to cool the contents to a desired temperature. The air is typically cooled by a vapor-compression system having a vapor compression cycle. Vapor compression based cooling systems can have low coefficients of performance of less than 2.[0005]Vapor compression based cooling systems cool all of the food products in a given cart to a fixed set temperature, which can preclude the transport of more than one food type. Moreover, the food product must be removed and heated by a separate piece of equipment, such...
