• the heat transfer plate 3 is in the form of a circular disk with an upward and downward protruding edge bead 12.
• the edge bead 12 engages behind the annular projection 5 of the plate 1, so that the plate 1 is supported on the edge bead 12, even if it faces the heat plate 3 Surface is not completely flat.
• An intermediate space 13 is formed between the dining plate 1 and the heat transfer plate 3.
• the edge bead 12 engages in the step 6 of the service plate 2 in order to form an intermediate space 14 between the heat transfer plate 3 and the bottom 8 of the depression of the service plate 2.
• the heat is transferred from the heated heat transfer plate 3 to the dining plate 1 essentially by convection in the intermediate space 13. Since the air in the intermediate space 14 has a higher temperature at the top and a lower temperature at the bottom, there is no convection there, so that heat from the heat transfer plate 3 to the service plate 2 only by heat radiation and conduction through the resting, poor conductive air in the space 14 passes, the heat loss is low there.
• the space 14 should not be chosen too narrow.
• the inner diameter of the ring-shaped dining plate projection 5 is equal to the diameter of the ring step 6.
• the ring bead 12 can be on its upper and / or lower Shaped side with a ring step, which enables the shown and described positive locking despite the diameter difference.
• the heat capacity of the heat transfer plate 3 is to be dimensioned such that it is sufficient to keep the dinner plate 1 with the dishes served there warm for a reasonable time, if it has previously been heated to a certain temperature, which should not be too high for practical reasons .
• the diameter of the heat transfer plate 3 is predetermined by the dinner plate 1, and its thickness is limited because its use should not significantly increase the distance of the dinner plate 1 from the service plate 3 for reasons of convenience when eating.
• the weight of the heat transfer plate 3 should not be too high for easy handling.
• the material of the heat transfer plate should be selected on the basis of these aspects (density and specific heat). It has been shown that, for example, aluminum heat transfer plates which are heated to approximately 250 ° C. are suitable.
