Description

Technical Field

[0001] The utility model relates to the technical field of heat-insulating plates for container containers, in particular to a spliced ​​small heat-insulating bearing plate. Background Art

[0002] As the weather turns cold, the food gets cold while eating, and the taste of the dishes deteriorates. Using an induction cooker or a microwave to heat the food, repeatedly heating the food at high temperatures can easily cause the loss of nutrients, which is detrimental to people's health. At present, the conventional insulation method is to optimize the setting of the dining table so that it has a heating function, thereby heating the dining table board surface, so that the heated dining table board can heat the food holding vessel placed on the dining table by heat conduction. However, this insulation method is limited by the surface area of ​​the dining table and requires a large number of heating units to cover the entire tabletop. When in use, the entire dining table is heated, so that most of the areas where the vessels are not placed have the defect of heat loss and excessive waste of energy, and the heating of the entire surface of the dining table will also cause the dining table to be unable to place cold dishes that need to be kept at a low temperature or room temperature, which can easily cause the cold dishes to be heated and affect the taste.

[0003] Although, existing patent documents limit the heating area by developing heated dish turntables and cutting boards to achieve the placement of hot dishes and cold dishes on the dining table in different areas, so that the hot dishes on the dish turntable and cutting board can be effectively insulated by heat conduction, while the cold dishes directly placed on the dining table can maintain a normal or low temperature taste. However, the existing dish turntable uses electric heating to heat the plates and bowls by setting a heating wire on the lower surface of the turntable. Since the placement surface of this turntable is a plane, the placement surface of general plates and bowls has a circle of convex ridges for stable placement, which is actually in close line contact with the surface of the turntable, with a small contact area and poor insulation effect. The existing dish turntable has a relatively fixed placement surface area, which is generally suitable for round tables with a larger load-bearing plane and is used to heat more dishes and utensils. When faced with the 2-5 dishes prepared for ordinary meals of regular families, the heating support plate provided is too large and is not conducive to the placement and use of small-sized families. The heating turntable or the overall plate-shaped heating module cannot effectively adapt to the actual dining situation with fewer dishes, which can easily cause a lot of energy waste. In addition, the entire plate or plate surface cannot be controlled in a single zone, which is not convenient for use by regular small families. In addition, the complete plate-shaped heating plate cannot adapt to the actual dish placement needs. When the placement needs to be adjusted according to the number of people, due to the poor matching of the plate plane and the serving plate body, adaptive adjustment of various placement methods cannot be performed, resulting in energy waste and inability to fully heat.
