Control method for automatic door opening and closing of household refrigerator

Abstract

The invention discloses a control method for automatic door opening and closing of a household refrigerator. The method includes the following steps of detecting the distance D between the standing position of a human body and the refrigerator, calculating the standing still time T of the human body, judging whether operation is performed on a display key operating interface within 30 seconds or not, judging whether the refrigerator is at a door closed state or not, judging whether D is lower than a first preset value D1 or not, judging whether T is higher than a first preset value T1 or not,judging whether D is higher than a second preset value D2 or not, judging whether T is higher than a second preset value T2 or not, and controlling a door of the refrigerator to be opened or closed. By detecting the distance between the human body and the refrigerator through a human body position detecting sensor and calculating the standing still time of a user, the opening and closing of the door of the refrigerator are judged and controlled, the user can open or close the door of the refrigerator without using a hand, the two hands of the user are effectively freed, and high-quality service is more intelligently provided for the user.

Description

technical field [0001] The invention belongs to the technical field of refrigerator control, and in particular relates to a control method for automatically opening and closing a door of a household refrigerator. Background technique [0002] With the advancement of science and technology, refrigerators are developing towards a more intelligent direction, among which automatic door opening and closing is the general trend. At present, the automatic door opening and closing technology in the refrigerator industry is mainly realized through voice recognition technology, human gesture judgment and other technologies. Voice recognition technology depends on the network. If the refrigerator is not connected to the network, or the connection network fails, the automatic door opening and closing cannot be realized; Human gesture judgment requires gestures to determine the door opening and closing requirements. When users take things from the refrigerator or put things into the refr...

Problems solved by technology

At present, the automatic door opening and closing technology in the refrigerator industry is mainly realized through voice recognition technology, human gesture judgment and other technologies. Voice recognition technology depends on the network. If the refrigerator is not connected to the network, or the connection network fails, the automatic door opening and closing cannot be realized; Human gesture judgment requires gestures to determine the door opening and closing requirements. When users take things from the refrigerator or put things into the refrigerator, they often hold items in both hands, and cannot conveniently perform door opening and closing gestures.
