Pot cover, pot and preservation method for food in pot

Abstract

The invention discloses a pot cover which comprises a pot cover body, a sterilizing module, a control device and a shielding module, wherein the sterilizing module comprises an ultraviolet LED lamp, and a light guide pillar is arranged at the light emitting side of the ultraviolet LED light. The pot cover has the advantages that the sterilizing effect is good, and the ultraviolet light is long in service life. The invention also discloses a pot which comprises a pot body and the pot cover covering the pot body. The pot has the advantages that the sterilizing effect is good, and the ultraviolet light is long in service life.The invention further discloses a pot additionally provided with a heat preservation module electrically connected with the control device, wherein the control device is arranged on the pot body and / or the pot cover body and is connected with the heat preservation module or a temperature sensor. The pot has the advantages that the sterilizing effect is good, and the ultraviolet light is long in service life. The invention further discloses a preservation method for food in the pot, which comprises the steps: during cooking, a shielding part covers the pot, a light passage is sealed; and after cooking is ended, preset sterilizing temperature is reached, the shielding part is opened, the light passage is opened, the ultraviolet LED light is turned on, and ultraviolet light is transmitted via the light guide pillar and penetrates through the light emitting side of the sterling module to irradiate food in the pot. The method has the advantages that the operation is simple and convenient, the sterilizing effect is good, and the preservation effect is good.

Description

technical field [0001] The invention belongs to the technical field of kitchen utensils, and in particular relates to a pot cover, a pot and a fresh-keeping method for food in the pot. Background technique [0002] With the improvement of living standards, people's requirements for quality of life are also getting higher and higher. Usually food (such as rice, soup, porridge) tastes bad after being kept warm in the electric cooker for a long time and is easy to breed bacteria. For example, food such as rice in the electric cooker is in the range of 25-40°C, which is easy for bacteria to multiply and deteriorate. [0003] In the existing technology, an ultraviolet lamp is usually used in the pot cover to directly irradiate the food in the pot to realize the function of disinfection and sterilization, so as to ensure the quality of the food. But in actual use, when the pot (rice cooker, pressure cooker, etc.) is cooking rice or porridge or other foods (such as soup, vegetable...

AI Technical Summary

Problems solved by technology

But in actual use, when the pot (rice cooker, pressure cooker, etc.) is cooking rice or porridge or other foods (such as soup, vegetables), it is easy to throw rice soup or liquid with other food residues on the pot cover, which is affected by these impurities ( food residue in the pot), the transmittance of the ultraviolet lamp is too low, which leads to the reduction of disinfection and sterilization, and cannot guarantee the freshness of the food in the pot. The transmittance of the deep ultraviolet lamp is more easily affected by impurities; in order to ensure the light effect, usually The ultraviolet lamp is closely attached to the quartz glass for light output on the pot cover, and the ultraviolet lamp is easily damaged by the high temperature erosion in the pot
