Opening method for refrigerator door body and refrigerator

Abstract

The invention provides an opening method for a refrigerator door body and a refrigerator. The refrigerator is provided with a somatosensory detector and an ultrasonic sensor which face towards the front area of the refrigerator. The opening method for the refrigerator door body comprises the steps that the front area of the refrigerator is detected through the somatosensory detector to judge whether a user appears in an area away from the refrigerator by a first preset distance; after the user appears in the area away from the refrigerator by the first preset distance, the ultrasonic sensor is started to obtain an ultrasonic signal reflected by the user, the sensing range of the ultrasonic sensor is configured to be an area away from the refrigerator by a second preset distance, and the second preset distance is smaller than the first preset distance; and after the ultrasonic signal is obtained, a power-assisted switch assembly of the refrigerator door body enters a work preparing state. According to the scheme, the situation that the refrigerator door body is automatically opened due to accidental touch can be effectively avoided, and the user experience in using is improved.

Description

technical field [0001] The invention relates to the field of home appliance control, in particular to a refrigerator door opening method and a refrigerator. Background technique [0002] With the development of society and the improvement of people's living standards, people's functional requirements for refrigerators are not only traditional storage, but also intelligent. [0003] In the current French side-by-side refrigerators, the traditional way to open the freezer drawer is that the user pulls the handle hard to overcome the resistance of the drawer to open it. However, due to the low temperature of the freezer compartment, the pressure difference between the inside and the outside makes it difficult to open the door. In order to solve this problem in the prior art, various ways of assisting the door opening have been proposed. One of the working principles of automatic opening of the freezer drawer is as follows: an operating button or other operating device is set o...

AI Technical Summary

Problems solved by technology

Since the freezer is generally set at the bottom of the refrigerator and its position is low, children can also touch the operating device, and it is easy to open the door when playing, resulting in leakage of cold in the freezer and affecting the freezing effect of the stored items in the refrigerator. Affect the user experience

Worse yet, children may enter an open freezer unnoticed and have accidents
