During the use of the bathroom mirror, because the temperature and humidity of the bathroom environment increase significantly, especially in the time period when the temperature is relatively low, the heating efficiency of the mirror surface on the bathroom mirror usually lags behind the heating efficiency of the bathroom environment. The air in the mirror contacts the mirror surface and forms condensation, which makes the mirror surface unusable due to fogging; for this reason, many bathroom mirror cabinets or mirror surfaces with defogging functions have been disclosed in the current process.
If the user is required to manually turn on and off the defogging function, it is obviously inconvenient and will affect the user's experience. Therefore, many technical solutions for controlling bathroom mirror cabinets or mirror defogging have been introduced in the current process, most of which use real-time technology. Real-time monitoring of bathroom temperature changes or real-time monitoring of mirror reflection is achieved: real-time monitoring of bathroom temperature changes is less accurate, and there is a certain probability of false opening or closing; real-time monitoring of mirror reflection requires the use of infrared or visible light and other sensing equipment, which is expensive and expensive. The installation and use are relatively complicated, and the market competitiveness is weak, which is not conducive to application promotion.
