Automatic control system for pushing separating plate of refrigerator

Abstract

The invention discloses an automatic control system for pushing a separating plate of refrigerator. The system comprises a guide rail, a gravity sensor, a digital analog converter, a control circuit, a driving motor and a rotating wheel, wherein the guide rail consisting of an upper guide rail and a lower guide rail is arranged in the inner wall of a box body; the gravity sensor is used for detecting the gravity on the separating plate and converting the detected gravity into an analog signal; the digital analog converter is used for converting the analog signal into a digital signal to be used as the input of the control circuit; the control circuit is used for acquiring the gravity value and comparing with the preset gravity value, and generating a driving signal to output when the acquired gravity value is more than the preset gravity value; the driving motor is used for generating a rotating power according to the driving signal and outputting through an output shaft; the rotating wheel is arranged on the side edge of the separating plate and clamped between the upper guide rail and the lower guide rail, and a shaft of the rotating wheel is connected with the output shaft of the driving motor; the rotating wheel can move in the upper guide rail and the lower guide rail to push in or out the separating plate based on the received rotating force. The automatic control system has the automatic detecting function and automatic pushing function, and prevents the separating plate from being damaged by overload.

Description

technical field [0001] The invention relates to an automatic control system for pushing refrigerator partitions, belonging to the technical field of refrigeration equipment. Background technique [0002] In order to preserve food and not easy to spoil, refrigerators are commonly used tools. In general refrigerators, the motor provides mechanical energy, and the compressor works on the refrigeration system. The refrigeration system is made of the principle of absorbing heat when evaporating and vaporizing the refrigerant with a low boiling point. Its advantages are long life and convenient use. The traditional refrigerators are all provided with partitions, which are used to separate the cabinet into several layers. The partitions are generally made of glass materials, which are movably arranged in the cabinet, and the partitions can be removed when cleaning is required Remove it, and insert it into the corresponding groove of the box after cleaning, and store items separa...

However, such a structure still cannot detect the weight of food placed on it, and does not have a push function

[0006] Therefore, the existing refrigerator partitions do not have automatic detection function and automatic push function when they are placed. When overweight is detected, the partition cannot be pushed out in time, and people cannot be reminded to reduce the pressure on the partition, thereby reducing the performance of the partition and shortening the service life of the partition
