Definitions
- the present invention relates to a food or beverage warmer with the features of the preamble of claim 1.
- Food or beverage warmers so-called energy-saving stoves
- a heat-insulating housing with a cooking space and a removable lid, and with a heating element assigned to the floor, which has an output of approx. 350 watts, for heating ready meals in packaging and beverages (hereinafter referred to collectively as products)
- products for heating ready meals in packaging and beverages
- a relatively large amount of water is evaporated, which initially condenses on the packaging wall, thereby transferring the heat to the food. Part of the steam escapes through an opening in the lid.
- the heating process ends when all the water has evaporated and the heating element therefore reaches a temperature of over 100 ° C.
- Food or beverage warmer for heating ready meals, eggs and for gently cooking raw food with a small water volume, which typically does not fully evaporate during operation, of typically only 5 to 100 ml, which, for example, heat a preserve of one liter content to approx. 90 ° C, are not known.
- the food or beverage warmer is provided with a heat-insulating housing which has a depression associated with the bottom wall, which is in heat-conducting connection with the heating element and which is set up to hold 5 ml to 100 ml of water, this small amount of water can be kept at a low level Energy use can be heated and the resulting
- Condense water vapor on the product Condense water vapor on the product.
- the product absorbs the thermal energy contained in the steam as evaporation energy and is heated.
- the housing also carries a temperature sensor in a side wall, the temperature of the cooking space can be determined and the heating solution can then be regulated or switched on and off. This temperature is more characteristic of the desired heating process than the temperature of the heating plate.
- the heating element preferably has a power consumption between 40 and 150 watts, in particular about 100 watts. This means that power supply is also easily possible in 12-volt and 24-volt systems.
- the heating element is a resistor with a positive temperature coefficient (PTC) that can be connected to a power supply with a nominal voltage between 12 and 14 volts and / or between 110 and 240 volts.
- PTC positive temperature coefficient
- the temperature sensor is arranged in a region of the housing adjacent to the ceiling wall and is set up to interrupt the power supply to the heating element at an especially selectable shutdown temperature between 85 ° C. and 98 ° C.
- heating plate there is preferably at least one spacer which holds a food or beverage container arranged thereon at a distance from the heating element.
- the vessel can have a closing lid with a pressure compensation opening and can thus be operated without pressure at any time.
- the lid is set up as a holding device for a plate.
- the housing wall is preferably made of a solid, washable plastic with an inner shell and an outer shell, between which an insulation layer is arranged.
- the performance of the at least one heating element can be limited to such an extent that it cannot reach a temperature on its intended power supply that reaches the flash point of the most flammable material used.
- an excess temperature fuse with a shutdown e.g. be provided at 105 ° C.
- FIG. 1 An exemplary embodiment of the present invention is described below with reference to the drawing.
- the single figure shows a food warmer according to the invention in a schematic cross section from the side.
- FIG. 1 shows a food warmer with a pot-shaped housing 1, which is heat-insulating with a sandwich-like wall made of 105 an inner shell 2, an outer shell 3 and a foamed insulation 4 arranged between them. These form a peripheral side wall 5 and a bottom wall 6 integral therewith.
- an opening 7 is provided to access 110 an interior 8, which can be closed with a cover 9.
- the lid 9 has a corresponding sandwich-like structure as the rest of the wall 5, 6. On its upper side, the lid 9 has a recessed grip 10.
- the lid has an opening (not shown) either at the edge or in its surface, 115 which builds up pressure Interior 8 prevented.
- the bottom wall 6 has bulges 12 facing the interior 8, which are set up in such a way that they keep a food vessel 13 placed thereon at a distance from the bottom wall 8.
- the food vessel 13 is held so that it can flow around from all sides.
- the bottom wall also carries heating elements 14, which act as PTC Resistors with a power consumption of approximately 100 watts are set up at the intended nominal voltage.
- the nominal voltage is 12 volts, 24 volts or 110 volts to 240 volts, depending on the version. It is also possible to provide the food warmer for use with different operating voltages.
- the heating elements are arranged in a trough 15 in which, during operation, there is a small amount of water, depending on the amount of food to be heated, for example between 5 ml and 100 ml. About 10% of the mass to be heated is sufficient.
- the side wall 5 carries in the area of the inner shell 2 adjacent to the opening 7 a temperature sensor 16 which measures the temperature of the interior 8 during operation. This temperature sensor is intended for the execution and determination of the end time of the regular heating process.
- a temperature fuse 17 is assigned to the bottom wall, which responds when an inadmissibly high temperature is reached in the interior and interrupts the heating output.
- the heating elements 14, which are thermally conductive to the depression 15 and the water, are supplied with an operating voltage and heat the water that
- the operating voltage 150 is switched off.
- the food is then heated to the desired degree and ready for consumption.
- the water in the trough 15 is then not yet completely evaporated so that the necessary energy is not used up.
- the amount of water has not been released to the environment in vapor form.
- the device can be used even where there is no powerful energy source, because 5 to 100 ml of water can be quickly evaporated even with a heating source of 50-150 watts and when the steam condenses on the tank wall and dripped back onto the hotplate, convert to steam again.
- the device can also be used 165 where previously devices with high energy requirements did the work.
- the device described so far like other embodiments of the present invention, has a thermally insulated one
- 175 housing with a closing lid and air compensation opening, both made of any thermally poorly conductive material, with one or more heating elements attached to the inner bottom of the vessel, with a calorific value of typically 30 to 150 watts, with at least one spacer in any shape as well as
- the dishes can, if they are heated in a water bath,
- 190 can be heated in your sales packaging or in a preferably supplied food storage container.
- the food or beverage warmer can be classified as safe from a fire protection point of view due to its low output.
- the device can be used in vehicles, airplanes, ships, households, 195 offices, canteens, restaurants, etc.
- the food or beverage warmer can also be operated with other heating sources (gas catalytic converter, etc.), although the advantage of fire safety is usually lost.
