Abstract

The invention discloses an electric heater which is used for heating the interior of a vehicle passenger room and mainly comprises a shell and a heating device, the heating device is installed in theposition, close to the center, in the shell, and the shell is installed below a passenger room seat and connected with a passenger room floor. The heating device is hung in the center area of the shell, the distance between the heating unit and the bottom face of the seat is increased, the situation that the seat face is overheated is reduced, and meanwhile enough space is reserved in the upper portion and the lower portion of the heating device and used for hot air convection and personnel maintenance.

Description

technical field [0001] The invention relates to the field of electric heating devices, in particular to an electric heater used for seats in passenger compartments. Background technique [0002] At present, domestic passenger room electric heaters are mostly installed under the seats in the passenger room, and are connected to the seat frame or the side wall. The electric heater installed on the seat frame is close to the seat surface, on the one hand, it is not conducive to the replacement and maintenance of the seat surface, on the other hand, the electric heater running for a long time will cause the seat surface to overheat; the electric heater installed on the side wall It is not conducive to the diffusion of hot air, and the electric heater will cause one side or part of the seat surface to overheat. Therefore, the power is limited by the temperature control unit, which cannot meet the heating load demand of the whole vehicle. [0003] Chinese patent CN104554311A disc...
