Abstract

The invention relates to the technical field of ovens, in particular to a steaming oven PTC thermistor heating element. The steaming oven PTC thermistor heating element comprises a PTC thermistor and riveting nails, wherein the PTC thermistor adheres to a PTC electrode plate which is riveted to a connecting wire, and a PTC packaging pressing sheet, a PTC packaging plate, a mica sheet, the PTC thermistor, the PTC electrode plate, a PTC insulating film and a PTC heat conducting sheet are sequentially placed between the riveting nails to be fastened in a riveted mode. The steaming oven PTC thermistor heating element is simple in structure, high in efficiency, low in power consumption and favorable for being maintained.

Description

technical field [0001] The present invention relates to the technical field of ovens, in particular to a steam oven. Background technique [0002] The evaporating tray structure of the existing steam oven, 1, the dry burning tube and the die-casting part are die-cast, and 2, the dry burning tube is connected with stainless steel welding and the like. [0003] In view of the design of the first method above, a die-casting mold is required to die-cast the structure of the dry-burning tube and the disc body, and the second method requires welding of the dry-burning tube and the disc body. The heating sources are all dry-fired tubes, and the heat energy is conducted to the die-cast or welded disc body to heat the water into steam during operation. When the dry burning tube of the two design methods is damaged, the entire steam assembly must be replaced. The production of parts is complicated, the evaporator is not maintainable, and the cost is high. Contents of the invention...
