Embodiment 1

[0047] An automatic door opening and closing system for a refrigerator, including a central processing unit, a voice module, a preprocessing module, an infrared sensor, an automatic door device, a WiFi module, and a remote data center, wherein the WiFi module and the remote data center are the networking communication module and the remote data center of the refrigerator. Remote database, used when the refrigerator is networkable.

[0048]The central processing unit is electrically connected to the voice module, the preprocessing module, and the infrared sensor respectively, and the automatic door device is electrically connected to the preprocessing module; the WiFi module is connected to the remote data center in communication, and the WiFi module is used to detect The data is transmitted to the remote data center and the data returned by the remote data center is transmitted to the central processing unit. The refrigerator can be connected to the Internet through the WiFi mo...

Embodiment 2

[0054] An automatic door opening and closing method for a refrigerator is realized by the above automatic door opening and closing system for a refrigerator, comprising the following steps:

[0055] A. The voice module transmits the acquired voice information to the central processing unit;

[0056] B. The central processing unit determines whether the current voice information belongs to the voice command for controlling the opening of the automatic door device or the voice command for controlling the closing of the automatic door device according to the pre-stored voice control command;

[0057] C. The infrared sensor detects whether there is a user within its measurement range, and when there is a user, obtains the distance between the user and the refrigerator and sends it back to the central processing unit:

[0058] C1. Infrared sensor detects whether there is a user within its measurement range, if there is, then enter step C2, if not, the result is fed back to the cent...

Embodiment 3

[0073] A. The voice module transmits the acquired voice information to the central processing unit;

[0074] B. The central processing unit determines whether the current voice information belongs to the voice command for controlling the opening of the automatic door device or the voice command for controlling the closing of the automatic door device according to the pre-stored voice control command;

[0075] C. Infrared sensor detects whether there is a user within its measurement range, and when there is a user, obtains the user's distance from the refrigerator and sends it back to the central processing unit:

[0076] C1. Infrared sensor detects whether there is a user within its measurement range, if there is, then enter step C2, if not, the result is fed back to the central processing unit;

[0077] C2. The infrared sensor detects the height of the current user and the distance m between the current user and the refrigerator, and transmits the height data of the current u...

Abstract

The invention discloses an automatic door opening and closing system of a refrigerator. The automatic door opening and closing system comprises a central processing unit, a voice module, a preprocessing module, an infrared sensor and an automatic door device. The central processing unit is electrically connected with the voice module, the preprocessing module and the infrared sensor correspondingly. The automatic door device is electrically connected with the preprocessing module. According to the automatic door opening and closing system, through voice and infrared sensing control, the problem that a user needs to open a refrigerator door first and then takes food into the refrigerator second when placing food or the problem that the user needs to take the food and put down the food and then closes the refrigerator door is solved, and user experience is improved.

Description

technical field [0001] The invention relates to the technical field of automatic door opening and closing of a smart refrigerator, in particular to an automatic door opening and closing system and method for a refrigerator. Background technique [0002] In the current environment of supply-side reform, technological innovation, product innovation and service innovation have become the main driving force for the development of refrigerator enterprises. With the acceleration of the intelligent development of home appliances, refrigerator products will continue to accelerate the process of intelligentization on the existing basis in the future, and consumers will have more choices. [0003] Although there are still some problems in the function and human-computer interaction of smart refrigerators, consumers' recognition is not high, and the entire industry lacks a unified technical standard, but there is no doubt that smart refrigerators will become the future development of t...
