Pot lid, pot and food preservation method in pot

Abstract

The invention discloses a cooker lid. The cooker lid comprises a cooker lid body, an ultraviolet sterilization module and a steam valve, wherein the steam valve comprises a valve seat arranged on the cooker lid body and a bonnet mounted on the valve seat, and an exhaust channel is formed between the valve seat and the bonnet; the ultraviolet sterilization module is arranged in the steam valve and can emit ultraviolet light to irradiate the exhaust channel of the steam valve. The invention further discloses a cooker. The cooker comprises a cooker body and the cooker lid, wherein the cooker lid body is arranged on the cooker body to cover the cooker body. The invention further discloses a preservation method for food in the cooker. According to the method, after food cooking, a control device controls an ultraviolet lamp in the steam valve to be switched on, and the ultraviolet lamp emits ultraviolet light which penetrates an ultraviolet light transmitting piece to irradiate the exhaust channel in the steam valve. The cooker lid, the cooker and the preservation method for the food in the cooker have the advantages that the sterilization efficiency is high, and bacteria can be inhibited from invading the food in the cooker.

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, etc., does not taste good after being kept warm in the rice cooker for a long time, and the air entering the pot through the exhaust channel of the steam valve contains a certain amount of bacteria, which makes the food in the pot easy to breed bacteria, such as , Rice and other foods in the rice cooker are in the range of 25-40°C, and bacteria are prone 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 ...

AI Technical Summary

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. For other foods (such as soup, vegetables), etc., it is easy to splash rice soup or liquid with other food residues on the pot cover. Affected by these impurities in the pot, the transmittance of the ultraviolet lamp is too low, not only the utilization rate of ultraviolet light is low, Moreover, the disinfection and sterilization effect is poor, and the freshness of the food in the pot cannot be guaranteed. It is necessary to sterilize the entire space in the pot, which makes the utilization rate of ultraviolet light lower.
