[0002] Smart heat preservation tables are currently widely used in schools, government agencies, hospitals, fast food canteens and other places, and can provide meals for multiple people at the same time. The heat preservation table has the function of keeping dishes warm, which can keep the dishes at a temperature that is beneficial to human health. The commonly used heating method is to heat the water in the sink to generate water vapor to heat the placed dishes, but this method has poor heating effect on the dishes and the dishes are heated unevenly. At the same time, the energy consumption of generating a large amount of water vapor is high, which increases the cost of equipment use. In addition, the commonly used heat preservation tables at present, in order to facilitate use in the canteen, will put the potted dishes into small bowls, and put the small bowls of dishes on the second floor for display and sale. Consumers choose the dishes they want to eat on the small bowls of dishes self-selection line. The traditional heat preservation table is heated by water vapor, which cannot reach the second floor to heat and keep the upper small bowls warm. In this process, tungsten filament heating tubes are generally used for lighting and heating. This heating method requires more electricity, is not conducive to the preservation of dishes, has poor heating effect, and has high cost of replacing parts and difficult maintenance.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present utility model are clearly and completely described below in conjunction with the accompanying drawings.

[0018] like Figure 1-2 As shown, the insulation table of the utility model includes a base cabinet 2 and an insulation layer 1. The insulation layer 1 is installed on the base cabinet 2 through a bracket to form an upper and lower layer structure, which is convenient for placing potted dishes in the base cabinet and small portions of dishes in the insulation layer.

[0019] The bottom cabinet 2 is provided with a bottom cabinet sink 20, and the bottom cabinet sink 20 is provided with a bottom cabinet heating pipe 24 to heat the water in the bottom cabinet sink 20 to generate water vapor, thereby keeping the basin dishes placed in the bottom cabinet sink 20 warm and heated. The bottom cabinet sink 20 is connected to a bottom cabinet drain pipe 21 at the lower end, and the bottom cabinet sink 20 is drained through the bottom cabinet drain pipe 21, which is convenient for controlling the amount of water in the bottom cabinet sink 20; the bottom cabinet drain pipe 21 is connected to a solenoid valve 30, which can accurately and automatically control the amount of water discharged into the bottom cabinet sink 20 through the bottom cabinet drain pipe 21. In a further embodiment, an upper water level detection device 22 and a lower water level detection device 23 are provided in the bottom cabinet sink 20. When the water level in the bottom cabinet sink 20 exceeds a set upper standard line, the upper water level detection device 22 detects and issues an early warning to avoid overflow caused by excessive water volume, etc. When the water level in the bottom cabinet sink 20 exceeds a set lower standard line, the lower water level detection device 23 detects and issues an early warning to avoid insufficient steam or dry burning caused by a small amount of water, etc.

[0020] The insulation layer 1 is provided with an insulation layer water tank 10, and the insulation layer water tank 10 is provided with an insulation layer heating pipe 18 to heat the water in the insulation layer water tank 10 to generate water vapor, so as to heat and insulate the small portions of dishes placed on the insulation layer water tank 10. The insulation layer water tank 10 is provided with an insulation layer upper water inlet 11 and an insulation layer lower water inlet 12. The insulation layer upper water inlet 11 is externally connected to an insulation layer upper water external pipe 14, and the insulation layer water tank 10 is supplied with water through the connection between the insulation layer upper water inlet 11 and the insulation layer upper water external pipe 14; the insulation layer lower water inlet 12 is externally connected to an insulation layer lower water external pipe 13, and the insulation layer water tank 10 is discharged through the connection between the insulation layer lower water inlet 12 and the insulation layer lower water external pipe 13. The tail ends of the insulation layer water supply external pipe 14 and the insulation layer water supply external pipe 13 are equipped with electromagnetic valves 30 for controlling the water flow and water volume of the upper and lower water, and maintaining the water volume in the insulation layer water tank 10. Preferably, the upper and lower water ports of the insulation layer water tank 10 are arranged at the side of the insulation layer water tank 10, and the outer sides of the insulation layer water supply external pipe 14 and the insulation layer water supply external pipe 13 are sheathed with stainless steel pipes, which not only facilitates the structural protection of the insulation layer water supply external pipe 14 and the insulation layer water supply external pipe 13 and the smooth flow of the pipes, but also increases the support between the bottom cabinet 2 and the insulation layer 1 and increases the stability.
