Description

Antibacterial cooking utensil

Technical Field

The invention relates to the technical field of household appliances, in particular to a bacteriostatic cooking appliance.

Background

With the rapid development of space science and technology, astronauts can use some kitchen electrical appliances in space, and the life quality of space is improved. Due to the particularity of the space environment, the safety and sanitation of the kitchen appliance are extremely important, which has great influence on the physical health of astronauts. Meanwhile, in recent years, diseases transmitted by viruses and bacteria are frequent, more people gradually select cooking food materials, the quality of healthy life is improved, and the safety and the sanitation in use of electric kitchen appliances are emphasized. Therefore, in both space life and daily life, the safety and sanitation of the kitchen electric appliance are problems which need to be solved at present.

In order to solve the technical problem, some cooking appliances use antibacterial structural members at the positions which are not easy to clean and easy to breed bacteria, so that the use safety and the use sanitation of the cooking appliances are improved, such as antibacterial sealing rings on covers of electric rice cookers. Because zinc oxide has the characteristics of high stability, good durability and the like, the zinc oxide is coated on the surface of the sealing ring or added into the sealing ring for bacteriostasis, but the actual bacteriostasis effect is poor, particularly food stains are easy to remain in a sealing part which is in sealing fit with the edge of the pot body, and the zinc oxide is not easy to clean, breed bacteria, and go moldy and smelly. Although the zinc oxide has the main bacteriostatic modes of photocatalysis bacteriostasis, metal zinc ion dissolution bacteriostasis and active oxygen bacteriostasis, at present, zinc oxide mainly dissolves bacteriostasis through metal zinc ions on cooking utensils, namely zinc oxide slowly releases zinc ions in a water-containing medium to destroy and kill cells so as to achieve the aims of sterilization and bacteriostasis. However, the existing sealing ring cannot provide a water-moistening environment, so that the zinc oxide antibacterial sealing ring cannot effectively sterilize and bacteriostat, the use safety and sanitation of the cooking utensil are reduced, and the user experience is poor.
