Embodiment 1

[0031] see figure 1 As shown, the present invention is an automatic locking device for a refrigerator, which includes a refrigerator door 300 and a refrigerator box 200, and also includes an electronic screen 400, an electromagnet 100 and an iron suction plate 101; the electronic screen 400 is arranged on the refrigerator door 300 Above, the electromagnet 100 and the iron suction plate 101 are respectively arranged at corresponding positions of the refrigerator door 300 and the refrigerator box 200 .

[0032] Preferably, the electromagnet 100 is arranged on the refrigerator door body 300, and the iron suction plate 101 is arranged on the refrigerator box 200 corresponding to the position of the electromagnet 100, and the electromagnet 100 generates a strong magnetic force to attract the iron suction plate 101. Thus, the refrigerator door body 300 is tightly closed.

[0033] Preferably, the electronic screen 400 includes a controller 401, a display screen 402, a human sensor m...

Embodiment 2

[0043] see figure 1 As shown, the present invention is an automatic locking device for a refrigerator, which includes a refrigerator door 300 and a refrigerator box 200, and also includes an electronic screen 400, an electromagnet 100 and an iron suction plate 101; the electronic screen 400 is arranged on the refrigerator door 300 Above, the electromagnet 100 and the iron suction plate 101 are respectively arranged at corresponding positions of the refrigerator door 300 and the refrigerator box 200 .

[0044] Preferably, the electromagnet 100 is arranged on the refrigerator box 200 , and the iron suction plate 101 is arranged on the refrigerator door 300 corresponding to the position of the electromagnet 100 .

[0045] Preferably, the difference between the electronic screen 400 and the first embodiment is that the electronic screen 400 also includes a height identification module for measuring the height of the person in front of the refrigerator. The height identification mo...

Abstract

The invention discloses an automatic locking device and awakening method for a refrigerator, and relates to the technical field of refrigerators. The device comprises a refrigerator door body, a refrigerator body, an electronic screen, an electromagnet and an iron attraction plate. The electronic screen is arranged on the refrigerator door body, and the electromagnet and the iron attraction plateare arranged at corresponding positions of the refrigerator door body and the refrigerator body respectively. The identity of a user in front of the refrigerator is recognized through a camera, the identity of the user in front of the refrigerator is compared with the identity, which is preset in the system, of the user who has the right to open the door, the electromagnet carries out attraction or outage operation by receiving a signal transmitted by a controller in the electronic screen, and therefore the identity of the user is automatically recognized. The purpose of locking or unlocking the refrigerator door is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigerators, and in particular relates to an automatic locking device and a wake-up method for a refrigerator. Background technique [0002] The refrigerator uses the door seal magnetic strip to attract the refrigerator door and the refrigerator box to avoid heat exchange inside and outside the box, thereby maintaining the low temperature state in the refrigerator. However, the internal volume of large refrigerators is large, especially due to differences in consumption habits at home and abroad, refrigerators for export usually have a large single internal space, children are naturally lively and active, and may enter such a large space. Due to the magnetic force of the door seal, it takes a certain amount of strength to push the door open from the inside of the refrigerator. If the child's strength is insufficient, coupled with the lack of air for a long time, it will easily lead to the danger of suff...
