A kind of steam table
Technical field
The utility model relates to a kind of steam table, particularly a kind of multi-functional Composite dinner table structure that is applicable to family or restaurant.
Background technology
The northern area of China because winter, temperature was low, food on the dining table can be cold must be than comparatively fast, and people are long mealtime, people's edible cold dish of having to perhaps will be edible again after cold food backheat again.
The utility model content
The purpose of this utility model is to examine filter the problems referred to above and a kind of steam table that can make meal insulation is provided.
The technical solution of the utility model is: a kind of steam table, comprise desktop, heat retaining and exothermal film, power control unit, thermometric device, thermal insulation board, power line and drain pan, wherein the heat retaining and exothermal film is installed in the lower surface of desktop, the thermometric device be installed in the heat retaining and exothermal film below, the corresponding heat retaining and exothermal film location of drain pan is installed in the below of desktop, thermal insulation board places on the drain pan, and power control unit is positioned at the top of thermal insulation board, and thermometric device, power control unit and power line connect successively.
Above-mentioned heat retaining and exothermal film directly is printed on the lower surface of desktop, or pastes the lower surface of desktop.
Above-mentioned desktop is square or circular.
Above-mentioned desktop is armorplate glass, microcrystal glass plate or poly (methyl methacrylate) plate.
Above-mentioned heat retaining and exothermal film is carbon film, metal film, rare earth film or PTC heater element.
Above-mentioned power control unit is mechanical switch formula control module or circuit board control module.
Above-mentioned power control unit is the circuit board control module, comprises switch, Thermal Cutoffs and thermoregulator, and switch, Thermal Cutoffs, thermoregulator and thermometric device are connected in series.
Above-mentioned thermometric device is thermistor or Thermal Cutoffs.
The utility model its advantage of comparing with ordinary table is: at cold winter, people can be placed on steam table with food and be incubated, and food is turned cold, and help the healthy of people, have improved people's quality of the life greatly.The utility model steam table dependable performance, simple in structure, easy to operate.

The specific embodiment
Embodiment:
The utility model steam table structure as shown in Figure 1, comprise desktop 1, heat retaining and exothermal film 2, rate control module 3, thermometric device 4, thermal insulation board 5, power line 6 and drain pan 7, wherein heat retaining and exothermal film 2 is a carbon film, metal film, rare earth film or PTC heater element, heat retaining and exothermal film 2 directly prints or sticks on the lower surface of desktop 1, for thermometric accurate, thermometric device 4 is close to the lower surface that is installed in heat retaining and exothermal film 2, drain pan 7 corresponding heat retaining and exothermal films 2 positions are installed in the below of desktop 1, thermal insulation board 5 places on the drain pan 7, power control unit 3 is positioned on the thermal insulation board 5, thermometric device 4, power control unit 3 and power line 6 are electrically connected successively.In the present embodiment, drain pan 7 is hollow structure, and its upper end open is tightly packed in the lower surface of desktop, and thermal insulation board 5 places the upper surface of drain pan 7 inner bottom parts, and shape and drain pan 7 bottoms match.
Above-mentioned thermometric device 4 is thermistor or Thermal Cutoffs.In the present embodiment, thermometric device 4 is a thermistor.
Above-mentioned desktop 1 is square or circular.In the present embodiment, desktop 1 is square.
Above-mentioned desktop 1 is armorplate glass, microcrystal glass plate or poly (methyl methacrylate) plate.In the present embodiment, desktop 1 adopts microcrystal glass plate.
Above-mentioned power control unit 3 is mechanical switch formula control module or circuit board control module.In the present embodiment, as shown in Figure 2, above-mentioned power control unit 3 is the circuit board control module, comprises switch 31, Thermal Cutoffs 32 and thermoregulator 33, and switch 31, Thermal Cutoffs 32, thermoregulator 33 and thermometric device 4 are connected in series.
When the utility model steam table uses, after power line 6 is inserted on the commercial power socket, press the power connection that switch 31 makes steam table, heating film 2 has electric current by just beginning afterwards heating, can need the size of holding temperature this moment by thermoregulator 33 manual adjustments, and the design temperature control range of present embodiment is 60 ℃~120 ℃.When unusual or High Temperature take place when, i.e. temperature too high (above 140 ℃), thermometric device 4 signal feedback to power control unit 3; Thermal Cutoffs 32 will fuse automatically; cut off the electricity supply, safety problems such as on fire do not take place in the safety with the protection steam table.When the heating film adstante febre, drain pan 7 can comparative heats, therefore, by placing the thermal insulation board of being made by aluminium platinum paper 5 on the drain pan 7 heat insulation, greatly reduce the temperature of drain pan, thereby too high with the temperature of avoiding drain pan.
The operation principle of the utility model steam table is: heating film 2 is equivalent to a very big and heating resistor that resistance is very little of heating area, as electric current the time by heating film, heating film then sends infrared ray and produces heat Heating table panel, thus indirect be placed on food above the desktop.
Steam table of the present utility model can be embedded on the table of the middle perforate of desktop, and for example hot pot table also can connect a table support 8 below desktop.
