Smart Bathroom Mirror Defogging Function Description
Many homes now have bathrooms and like to have mirrors in them. However, after people take a bath, the mirror will be covered with a layer of fog, which affects the use of the mirror. It is necessary to wipe the mirror with hands or a towel. However, after bathing, people are reluctant to touch foreign objects due to hygiene considerations. If they use a towel to wipe, they also need to wash the towel, which increases the workload of housework, brings a very bad bathing experience to people, and seriously affects people's bathing. Feeling.
Outdated bathroom mirror defogging technology
In the prior art, the water mist on the mirror is mainly removed by means of an automatic erasing device or by arranging a fan and a heater around the mirror. The disadvantage is that no matter the additional equipment of the automatic erasing device affects the beauty of the sperm, in addition, the dust and water mist of the automatic erasing device itself need to be manually erased.
Smart mirror advanced defogging technology
The characteristic of the intelligent bathroom mirror defogging is that the device also includes an infrared emitting device, an infrared receiving device, a heating wire coil, a microcontroller, a rectifier diode, a step-down transformer, a fuse and a thyristor; the infrared emitting device and the infrared receiving device are installed in the On the back of the mirror, the mirror body is not provided with a coating where the infrared rays are irradiated, and the infrared emitting device and the infrared receiving device are electrically connected to the microcontroller; the heating wire coil is arranged in a ring shape on the back of the mirror body, one end is connected to the fuse and the step-down transformer, and the other end is connected to the fuse and the step-down transformer. The thyristor is connected to the microcontroller; the microcontroller is connected to the step-down transformer through a rectifier diode to connect the power supply, and the microcontroller is installed in the frame of the mirror body. Further, the infrared emitting device and the infrared receiving device are installed on the front of the mirror.
Further, the infrared emitting device and the infrared receiving device are installed in the middle of the ring formed by the two heating wires of the heating wire coil to prevent the mirror mist near the heating wire coil from being removed first, and the microcontroller disconnects the circuit in advance. When in use, the device is powered on, and the microcontroller controls the infrared emitting device. If the infrared receiving device can receive infrared rays, it is determined that the surface of the mirror is not blocked, that is, there is no fog, and the heating wire coil circuit is disconnected; when the infrared receiving device cannot receive it. In the case of infrared rays, the microcontroller controls the thyristor to connect to the heating wire coil circuit, and the heating wire coil is energized to generate heat to remove the water mist. After the mist and water are removed, the infrared receiving device receives the infrared ray to judge the intensity, and the microcontroller controls the thyristor to disconnect the circuit. .
