Pot cover, pots and method for preserving freshness of food in pots

Abstract

The invention discloses a pot cover. The pot cover comprises a pot cover body, a sterilization module and a control device, wherein the sterilization module comprises an ultraviolet light-transmitting piece, and an ultraviolet lamp arranged in an accommodating space between the pot body and the ultraviolet light-transmitting piece, the ultraviolet lamp is electrically connected with the control device, and the pot cover body is provided with a cleaning module used for cleaning the light-emitting side of the ultraviolet light-transmitting piece; the ultraviolet transmissivity is high, and the sterilizing effect is good. The invention further discloses a pot, wherein the pot comprises a pot body and the pot cover which covers the pot body; the ultraviolet transmissivity is high, and the sterilizing effect is good. The invention also discloses another pot, wherein a thermal insulation module electrically connected with the control device is additionally arranged; the control device is arranged on the pot body and/or the pot cover body, and is connected with the thermal insulation module or a temperature sensor; the ultraviolet transmissivity is high, and the sterilizing effect is good. The invention further discloses a method for preserving freshness of food in the pots; according to the method, after boiling of the food, when the temperature inside the pot is reduced to the preset sterilization temperature, the ultraviolet lamp is started, and when the temperature inside the pot is reduced to the preset sterilization temperature, the cleaning module is started; the operation is simple and convenient, the disinfection and sterilization effects are good, and the freshness 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, the 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. However, in actual use, the pot (rice cooker, pressure cooker, etc.) Food (such as soup, vegetables), etc., it is easy to throw rice so...

Problems solved by technology

[0003] In the existing technology, the 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. However, in actual use, the pot (rice cooker, pressure cooker, etc.) Food (such as soup, vegetables), etc., it is easy to throw rice soup or liquid with other food residues on the lid of the pot. The high temperature in the pot is easy to form water vapor. Affected by these impurities (water vapor, food residues in the pot), ultraviolet The transmittance of the 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 deep ultraviolet LED lamps is more easily affected by impurities
