New description: [New technical field] This creation is about a door structure, especially a door structure with intercom and peep window. [Prior Art] The general residential building is equipped with a door-to-door intercom system, which provides intercommunication between the residents on each floor and the visitors at the entrance of the building. 'The door intercom system usually also has a camera and a display screen for the resident to identify the visitor. And carry out access control. However, the building is complicated or because the visitors are not familiar with the door intercom system; often visitors do not pass through the door intercom system, that is, they directly enter the building and directly knock at the door of the building. At this time, the residents can only use the cat's eye installed on the door panel. , watch visitors. In order to protect the privacy of the residents, the size of the cat's eye is small, so that outdoor personnel can directly see the indoor situation. Relatively speaking, when the household is watching the outdoor condition from the cat's eye, it is not only very close to the cat's eye, but also very laborious to watch. And its visual range is also limited. If the visitor's standing position is out of the visible range of the cat's eye or the visitor's height is short, it is difficult for the resident to identify the visitor's identity by the cat's eye, making it difficult for the resident to make a decision whether or not to open the door to accept the visit. In order to solve the above technical problems, there has been a peeping window structure disposed on a door panel in the market which mainly uses a voltage to change a liquid transmittance. When the power is turned off, the liquid crystal film is opaque to maintain the privacy of the vine. When the power is turned on, the liquid crystal film is transparent ί = Γ outdoor conditions and visitor identity. Since the liquid crystal film is opaque when it is not energized, its mounting area is not limited, so 3 M414479 solves the disadvantages of the laborious viewing and narrow viewing range of the conventional cat eye device. The above-mentioned liquid crystal film which can change the light transmittance is used as a peeping window structure on the door panel, and has been found in many prior patents, such as the patents of No. 9622〇795, No. 097, No. 098209〇16, and the like. China's patents such as 92241885.3 and 93238267.3. The above-mentioned prior patents and the conventional liquid crystal thin-view window structure are not equipped with a walkie-talking device. If the visitor is an unfamiliar visitor, the resident can watch the window structure of the liquid crystal film, but cannot understand the meaning through the intercom device. 'It also makes it difficult for residents to decide whether to open the door to accept the visit of the strange visitor. Since the standby liquid crystal film prying window structure changes its light transmittance by energization, 'physical wiring work is inevitably required, and the above-mentioned prior patents and conventional liquid crystal film peeping window structures must be in the door panel or building for wiring. The hole in the wall is drilled through the hole and the cable is connected. The wiring is mostly in the form of a clear line. It is exposed on the door panel, which not only damages the finish of the door panel, but also destroys the aesthetics of its appearance. In view of the shortcomings of the above-mentioned conventional techniques, the creators of this case, after many years of painstaking research and research, finally succeeded in researching and developing the structure of the door with the intercom and the window. [New content] The purpose of this creation is to provide a door with a liquid crystal film peeping window, which is equipped with a pair of peasant houses. The occupant can not only view the outdoor condition and the visitor identity through the liquid crystal film, but also The intercom rumor understands the visitor's intention to 'make the right judgment to make a door open to accept the visit.'
