Pot cover, pot and fresh-keeping method for food in pot

Abstract

The invention discloses a pot cover. The pot cover comprises a pot cover body, a sterilizing module, a control device and a shielding module, wherein the sterilizing module comprises an ultraviolet lamp; the shielding module comprises a shielding piece which is movably arranged on the pot cover body; and a light channel between the sterilizing module and the pot body can be closed or opened by the shielding piece. The ultraviolet transmittance is high, and the sterilizing effect is good. The invention further discloses a pot, a heat insulating module which is electrically connected with the control device is added, the control device is arranged on the pot body and / or the pot cover body, and is connected with the heat insulating module or a temperature sensor; and the ultraviolet transmittance is high, and the sterilizing effect is good. The invention further discloses a fresh-keeping method for food in the pot. The fresh-keeping method for the food in the pot comprises the following steps: closing the shielding piece in a food cooking process, and closing a light channel between the sterilizing module and the pot body; and after cooking of the food is finished and when the temperature reduced to a preset sterilizing temperature, opening the shielding piece, and turning on an ultraviolet lamp. Operation is simple and convenient, the sterilizing effect is good, and the fresh-keeping 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.) For food (such as soup, vegetables), etc., it is easy to throw ric...

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.) For 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. Affected by these impurities (food residues thrown into the pot), the transmittance of the ultraviolet lamp is too low, which leads to disinfection and sterilization The reduction of the food in the pot cannot guarantee the freshness of the food, and the transmittance of the deep ultraviolet LED lamp is more easily affected by impurities
