High-temperature electrothermal sterilizing cabinet with homogeneous temperature field

Abstract

The electrothermal sterilizing cabinet includes cabinet, back heating pipe with power accounting for 33-43 % of total power, bottom heating pipe with power accounting for 57-67 % of total power, doorand control circuit connected to the heating pipes. Owing to the reasonable distribution of heating power in the heating pipes, the sterilizing chamber has improved temperature homogeneity and controlled maximum temperature below 170 deg.c, lower than the temperature limit of heat insulating polyurethane material and without fire danger and damage to sterilized tableware and other articles. Thepresent invention has smart design, high sterilizing effect, good use performance and high safety performance.

Description

1. Technical field: [0001] The invention is an electric heating disinfection cabinet, especially a high-temperature electric heating disinfection cabinet with a uniform temperature field. 2. Background technology: [0002] The high-temperature disinfection chamber of the existing vertical tableware disinfection cabinet (including single door, double door, and three doors) is a square box, and the five sides of the box wall except the door are double-layered with polyurethane hard foam and other thermal insulation materials in the middle. Metal plate structure, the door body adopts a double metal plate structure with an insulating interlayer or a structure with a glass window and a double-layer glass structure with an insulating air layer in the middle, and a flexible sealing strip is used between the door body and the box body to seal and insulate. The disinfection room of the disinfection cabinet is generally equipped with two far-infrared quartz heating tubes with the same...

AI Technical Summary

Problems solved by technology

In order to make the temperature at the midpoint of the door edge of the bottom shelf meet this requirement, the temperature at the midpoint of the inner surface of the upper shelf must reach 200°C, but this temperature has exceeded the temperature limit that the insulation layer can withstand, so that the insulation material is burnt , resulting in a decline in its thermal insulation performance; in addition, it also wastes electric energy, and there is a hidden danger of fire, and it is easy to damage the tableware and other devices in the disinfection cabinet

For this reason, many manufacturers of disinfection cabinets have to lower the standards, so that the temperature at the door cannot meet the requirements of the national standard, and the disinfection effect is greatly reduced.
