Abstract

A food warmer is installed in a vehicle and is connected to the vehicles heating system. The food warmer includes an enclosure where food is placed for warming. Heated fluid is circulated around a metal tube 14 that wraps around the enclosure, which is insulated 15 to prevent heat loss and is covered by an outer case 16. The food warmer is fitted with a door 11 preventing heat from escaping, an insulated handle 10, and a dial or knob (1, fig 1) to turn the warmer on and off and to choose temperature levels via a thermostat. The warmer may be connected to the fluid via fluid connectors (08, 09, fig 1).

Description

Food Warner This invention relates to a food warmer for vehicles.

Background

On journeys through high traffic environment such as on motorways, less developed city highways or even cross country, where it's hard to find facilities that provides heated nutritious essentials, there are times when toddlers cry for their bottle but parents find that the formula is ccld, times when we just want a warm drink, and there are other times especially in winter when we want a hot meal or to warm-up the provisions while travelling for long distances.

Statement of Invention

A food warmer installed inside the vehicle, which is connected to the (engine cooling system) vehicle's fluid heating system, or the Rapid Heater vehicle heating system's fluid flow line and fluid return line adjacent to the heater matrix. As heated fluid occupies the vanes/ports of the metal tube that surrounds all the inner enclosjre (where food is heated) or the tubes are made into the inner enclosure as a single unit, the heat transferred is prctected by a circumference of insulation which confines heat centrally to the inner enclosure only. An outer casing that wraps all-around the food warmer so as to protect its inner essential parts, heat trapped inside the inner enclosure is secured by a thermal sealed door with an insulated handle. The food warmer is equipped with a dial which via a thermostat connected to the solenoid and battery relates temperature differences inside the inner enclosure, while visual indicators on the door and knob/dial displays on/off positions and temperature levels, a back light inside the food warmer aids visually while warming food.

The food warmer may be inside the vehicle and or underneath the radio or even occupies some of the space inside the glove compartment so it's out of reach to children etc. Advantages A food warmer will provide instant access to a facility that produces hot food or drink every time.

The food warmer uses existing energy and does not deplete or consume a separate fuel source such as the battery.

The food warmer can be made to deliver higher temperatures if use with the Rapid Heater vehicle heating system.

The food warmer is hygienic, does not produce ash from spent fuel, oil hi-products, smoke from the engine exhaust, carbon monoxide or carbon dioxide etc. The food warmer can be turned on or off when not in use.

A food warmer will allow for you never to miss breakfast, lunch or dinner again.

During winter the food warmer supplements thermoses and will always sustain heating food.

Description

The vehiclets engine is equipped with fluid/coolant heated by combustion that is also used as heating for passeflger inside the vehicle.

This invention will now be descried solely by the way ot example and with reference to the accompanying drawings in which: Fig 1 shows the different views of the food warmer, Knob 01, with visual calibrations 18, on the door 11, for choosing different warming levels. A top view 02, a bottom view 03, the right view 04, the left view 05, a view from the back 06 with the fluid flow 08 and fluid return connection 09, and the solenoid 12 that stops fluid movement when the food warmer is turned off. The door is hinge 07 in a position so as to aflow maximum access to the warming space inside the food warmer, and an insulated door handle 10 for safe access.

Fig 2 shows a partial cutaway view of the interior layers of the food warner.

The inner enclosure 13 consists of metal tube 14 wrapped all around a metal chassis but both can be manufactured as a single unit 13. It is covered with insulation 15 in order to prevent heat from escaping, and is protected by an outer case/cover 16 with a smooth surface so the door seals properly.

Fig 3 shows the controls 01, 10, 18 on the tood warmer's thermal sealed door 11 and insulated handle 10.

The rood warmer is installed arid connected to the engines cooling system's fluid line, as the engine produces heated fluid, it is then circulated through the tube wrapped all around and at the back or impregnated into the inner enclosure of the food warmer, this heated fluid heats the metal tube and in turn heats the entire inner enclosure which capturec and compacts heat to be utilised for cooking.

A food warmer installed inside the vehicle comprising of; An inner enclosure 13 that retains the food to be heated, consist of a metal tube 14 wrapped all around a metal chassis; but can be made as one unit 13, that connects to the engine cooling system's flow and return fluid lines for the heated fluid to circulate through, heat resistant material 15 prevents heat loss and keeps the heat central to the rood warmer's inner enclosure 13, An outer protective casing 16 covers and secures the food warmer's inner essential parts.

A thermal door 11 seals with the smooth surface 17 of the casing 16 and keeps heat inside the inner enclosure. An insulated handle 10 provides easy access to the food warmer by opening and closing the sealed heat resistant door 11, a thermostatic temperature knob/dial 01 that regulate food warming temperature via a thermostat placed on the body of the inner enclosure. An on/off indicator light 19 that indicates usage position and an an/off switch with heating levels which is integrated into the kflob/dial, a solenoid 12 stops the flow of fluid to the inner enclosure by default while on OFF, but is actuated by the thermostat via the battery and allows fluid to flow around the vanes/ports when turned to ON, the heating levels allow the choice of different temperature settings for warming food.

Claims

Claims A food warmer installed inside the vehicle, which is connected to the (engine cooling system) vehicle's fluid heating system, or the Rapid Heater vehicle heating system's fluid flow line and fluid return line adjacent to the heater matrix, As heated fluid occupies the vanes/ports of the metal tube that wraps all around and at the back of the inner enclosure (where food is heated) 13 or the tubes are made into the inner enclosure as a single unit 13, the heat transferred is protected by a circumference of insulation 15 which confines heat centrally to the inner enclosure only, An outer casing 16 that wraps all-around the food warmer so as to protect its inner essential parts, heat trapped inside the inner enclosure is secured by a thermal sealed door 11 with an insulated handle 10, The food warmer is equipped with a dial/knob 01 which via a thermostat connected to the solenoid 12 and battery, relates temperature differences inside the inner enclosure, while visual indicators 18 on the door and knob/dial displays on/off positions, a back light inside the food warmer aids visually while warming food.1.
