Example 1:

fig. 1 shows a schematic structural view of a dining car with a heat preservation function, which comprises: the outer shell 1, the inner shell 2, level sensor 3, serving trolley handle 4, rear wheel 5, front wheel 6, heating wire 7, power 8, add water mechanism 9, drainage mechanism 10, the inner shell 2 encloses into the heat preservation cavity that holds food, form the water storage cavity between outer shell 1 and the inner shell 2, the back top of serving trolley is provided with serving trolley handle 4, the back below of serving trolley is provided with two rear wheels 5, the front below of serving trolley is provided with two front wheels 6, be provided with the heating wire 7 of feedwater heating and the power 8 that provides the electric energy for heating wire 7 in the water storage cavity, the serving trolley rear is provided with the filler, serving trolley the place ahead is provided with the outlet, the horizontal position of filler is higher than the outlet. The outer shell 1 and the inner shell 2 are made of stainless steel.

Example 2:

on embodiment 1's basis, 1 inner wall of shell is provided with level sensor 3, and when the water level height was less than level sensor 3, level sensor 3 sent the water level and crosses low signal, reminds the staff to add water. The level sensor 3 is installed at a position higher than the drain port and lower than the filler port in the horizontal direction.

Example 3:

in addition to the embodiment 2, the water adding mechanism 9 is provided at the water adding port, and the water discharging mechanism 10 is provided at the water discharging port.

Example 4:

on the basis of embodiment 3, as shown in fig. 2, the watering mechanism 9 includes a rubber plug 91 and a float 92 (the float is made of a material with a density smaller than that of water), a rubber plug opening 911 is provided below the rubber plug 91, the front end of the rubber plug 91 is set to be an inclined surface, a float protrusion 921 mutually matched with the rubber plug opening 911 is provided above the float 92, the rear end of the float protrusion 921 is an inclined surface, when the float protrusion 921 is clamped into the rubber plug opening 911, the rubber plug 91 cannot be pulled out from the watering opening, when the water level descends, the float 92 also descends along with the water level, and when the float protrusion 921 is separated from the rubber plug opening 911, the rubber plug 91 can be pulled out.

The water adding mechanism 9 has the advantages that: when the water level in the water storage cavity is close to the water filling port, the floater protrusions 921 are clamped into the rubber plug openings 911, so that the worker cannot pull out the rubber plug 91, and accidental scalding is prevented. Only when the water level drops to the safe height, the float projection 921 can break away from the rubber plug notch 911, and the worker can pull out the rubber plug 91.

Example 5:
