Problems solved by technology

[0008] The above two schemes also have disadvantages. In scheme (1), the silver ion concentration is ensured to a certain extent by retaining the design margin of the silver electrode, but therefore a large silver electrode is required, which leads to an increase in cost and causes the silver ion concentration to increase. Excessive hidden danger
In scheme (2), a variable electrolysis voltage is used to electrolyze the silver electrode with a constant current, thereby ensuring the concentration of silver ions. However, because the driving circuit of the constant current is complex and the constant current is not absolute, there is still a certain The deviation, so the accuracy and cost are not perfect

Abstract

The invention discloses a control method of an electrical appliance carrying out sterilization by using metal ions, which belongs to the field of electrical appliances. The problem that the concentration of metal ions cannot be accurately controlled in the prior art is solved. The technical scheme for solving the problem is as follows: detection is carried out multiple times by using a current detection circuit, normal electrolysis currents are accumulated, and the concentration of metal ions is fed back by using the magnitude of current obtained, thus realizing accurate control on the concentration of metal ions. The control method is mainly used in electrical appliances carrying out sterilization by using metal ions. In addition, the invention provides an electrical appliance which realizes sterilization by using the control method.

Description

technical field [0001] The invention relates to an electric appliance, in particular to a control method and the electric appliance which use metal ions to sterilize the electric appliance. Background technique [0002] In recent years, with the changes in the ecological environment, people's awareness of health has continued to increase. In terms of household appliances, people's demand for appliances with sterilization functions has continued to grow. From the current point of view, the sterilization methods mainly include the following types: solar radiation (ultraviolet) sterilization, high temperature sterilization, ozone sterilization, metal ion (silver ion) sterilization and so on. Among them, the metal ion sterilization method is widely installed in electrical appliances with a sterilization function due to its relatively simple conditions of use and relatively low cost. [0003] The module with silver ion sterilization function mainly uses the strong oxidation of s...
