Sterilization devices and household appliances

Abstract

An embodiment of the invention provides a bacterium removal device, and belongs to the field of electric appliances. The bacterium removal device comprises electrodes and a control circuit. The electrodes are used for electrolyzing substances in water or air to generate ions with bacterium removal activity after voltages are applied to the electrodes; the control circuit is used for providing the voltages to the electrodes, and the electrodes are connected with the control circuit. The invention further provides a household electric appliance. The household electric appliance comprises the bacterium removal device. The bacterium removal device and the household electric appliance have the advantages that harmful bacteria can be removed by the aid of electrochemical methods, accordingly, bacteria can be effectively removed, and harmful substances can be prevented in bacterium removal procedures; the bacterium removal device and the household electric appliance are low in energy consumption and accordingly are safe, and energy can be saved.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a sterilization device and household appliances. Background technique [0002] At present, household appliances are becoming more and more diverse, and as the use time of household appliances increases, harmful microorganisms such as bacteria are easy to breed in household appliances, especially in various kitchen appliances, the growth of microorganisms is not conducive to human health . Therefore, it is necessary to install a sterilizing device in the household appliance. [0003] At present, the commonly used disinfection mechanisms include high-temperature cooking and far-infrared disinfection. Infrared disinfection generates radiant heat through the heating of electric heating elements, destroying protein structures such as microorganisms and bacteria on the surface of tableware, denaturing them, and achieving the purpose of sterilization. However, whether it is high-tem...

Problems solved by technology

[0003] At present, the commonly used disinfection mechanisms include high-temperature cooking and far-infrared disinfection. Infrared disinfection generates radiant heat through the heating of electric heating elements, destroying protein structures such as microorganisms and bacteria on the surface of tableware, denaturing them, and achieving the purpose of sterilization. However, whether it is high-temperature cooking or Infrared disinfection has the disadvantage of consuming too much energy

[0004] In addition, there is an ultraviolet lamp sterilization device, which achieves the purpose of making it impossible to reproduce by destroying the DNA chain inside the microorganism body. However, the structure of the ultraviolet lamp sterilization device is complicated, and the ultraviolet rays emitted by the ultraviolet lamp are harmful to the human body. It is required to avoid personnel contact due to damage, which not only poses safety hazards, but also further increases the cost of installation and use

[0005] There are also defects in other existing sterilization methods, for example: plasma and negative ion sterilization do not have broad purification characteristics because of the limited working environment of plasma and negative ions; chemical sterilization and disinfection are prone to produce other harmful components to the human body; in ozone sterilization, ozone It is easy to release exceeding the standard, and it is easy to cause human injury, etc.
