At present, the elevator car is made of metal materials such as stainless steel, and in winter with cold weather, the temperature in the elevator car is lower, and some elevators supply heat to the whole elevator box by heating air, so that the energy consumption is higher, and on the other hand, the heat conveyed into the elevator car by the heating device can flow outwards, so that the heat is wasted outwards through the wall of the elevator car.

SUMMERY OF THE UTILITY MODEL

To the not enough with above-mentioned background art, the utility model provides a heatable car floor.

The utility model adopts the technical scheme as follows: a heatable car floor, the key lies in: the floor unit is connected with the heat insulation base through a clamping piece, a plurality of annular wire grooves are formed in the heat insulation base and correspond to the floor units one by one, heating wires are arranged in the annular wire grooves and connected in parallel, heat conducting frames are clamped on the heating wires and contacted with the heat conducting frames below the floor units, pressure sensors are arranged between the floor unit and the heat insulation base, and the pressure sensors and the heating wires are respectively electrically connected with a unit controller.

Preferably, a heat insulation cavity is arranged in the heat insulation base, and the heat insulation cavity is a vacuum cavity.

Preferably, the floor unit is a rectangular plate, the clamping piece comprises four clamping blocks arranged on the lower surface of the floor unit and clamping grooves arranged on the heat insulation base, and the four clamping blocks are close to the four corners of the rectangular plate.

Preferably, the heat conduction frame comprises a plurality of concave snap rings, the concave surfaces of the concave snap rings are attached to the surface of the heating wire, and the concave snap rings are connected with the same heat conduction net frame.

Preferably, the heating wire is a carbon fiber heating wire.

Preferably, a temperature protector is embedded in the floor unit.

Preferably, the pressure sensor is a membrane pressure sensor.

Has the advantages that: compared with the prior art, the heatable car floor provided by the utility model avoids the problem of too low surface temperature of the floor in winter, and changes the heat flow form in the car, so that the temperature uniformity of the air in the whole car is better; and through adopting the way of shunting control heating, can carry out local heat supply according to the position that the passenger stood in the car, the area is little, it is fast to heat up, reduce to the heat supply load requirement, the energy consumption is low, and set up the vacuum cavity in the heat-insulating base, play good thermal-insulated effect, reduce the heat and scatter and disappear, energy-concerving and environment-protective, share the partial work of air conditioner, reduce the interior circulating air volume of railway carriage or compartment, corresponding wind is made an uproar and is reduced, the comfort level of passenger improves, have fine economic benefits and social.
