Description

Efficient assembly structure of bathroom heater PTC heating element module Technical Field The utility model relates to the technical field of ice making devices, in particular to a high-efficiency assembly structure of a PTC heating element module of a bathroom heater. Background The conventional bathroom heater PTC heater module is generally assembled by adopting an integral metal frame structure, and a heater is fixed in a box body through welding or bolting. The common mode includes welding PTC heater directly onto metal rack, installing the heater to main frame or fastening the heater to the rack with several bolts, and installing protecting grille and cover plate. Although the structure can realize basic fixation, the structure has the problems of complicated assembly process, manual adjustment of positioning accuracy, tolerance and the like. In addition, the integral frame is easy to deform due to heat stress concentration under the high-temperature working condition, and poor contact or potential safety hazard can be caused after long-term use. Based on the structure, the traditional assembly mode has the obvious defects that firstly, special tools and skilled workers are needed for welding or bolting, the production efficiency is low, the cost is high, secondly, the integral frame is required to be disassembled for maintenance and replacement, and thirdly, the rigid connection is difficult to compensate the thermal expansion difference, and the structural deformation or the connection looseness is easy to cause.
