Description

Disinfection frame and disinfection cabinet

Technical Field

The invention relates to the technical field of kitchen equipment, in particular to a disinfection frame and a disinfection cabinet.

Background

The milk bottle disinfection mode in the disinfection cabinet comprises an ultraviolet ray mode and a heating mode, and ozone is not suitable for the disinfection of the milk bottle due to the existence of unpleasant smell:

(1) the milk bottle is disinfected by means of the irradiation of the disinfection light, and the light can not penetrate the glass or the plastic milk bottle wall because only the surface sterilization can be carried out; the internal sterilization can only aim the mouth of the feeding bottle at the lamp tube as much as possible, and the maximum amount of sterilization light is ensured to irradiate into the feeding bottle, but the lamp tube is positioned in the sterilization cabinet, and the size, shape deviation, feeding bottle placing position difference and the like of the feeding bottle hardly ensure that the mouths of all the feeding bottles can be over against the lamp tube; in order to sterilize the milk bottle comprehensively, the utility model patent of a sterilizing cabinet with the patent application number of CN201921217544.8 (with the publication number of CN211096254U) is specially provided with a first ultraviolet lamp tube for sterilizing the milk bottle, which can directly irradiate the inner surface of the milk bottle, and has the advantages of short acting distance, no dead angle, thorough sterilization and short sterilizing time; the second lamp tube is used for conventional disinfection, but the scheme needs to be specially provided with additional disinfection lamp tubes, so that the cost is higher, and the adaptability to the conventional common disinfection cabinet is poor;

(2) rely on the heat to carry out the feeding bottle disinfection, general sterilizer heating element arranges at the sterilizer bottom, and the feeding bottle bottleneck is invertd on the dense net shelf of drawer basket of heating bottom plate top, inside the hot gas flow rises and gets into the feeding bottle, the problem is: firstly, the bottle mouth is narrow, the quantity of heat entering the interior of the feeding bottle is limited, the plastic products can be burnt and melted due to overhigh temperature, and the sterilization effect is poor due to low temperature; secondly, if the bottom is buckled reversely, the sterilizing light is difficult to enter through the bottle mouth, and the sterilizing effect is not good; thirdly, the milk bottle is not stably placed;

similarly, other hollow objects to be sterilized such as nipples, cups, etc. having openings have similar problems.
