The invention discloses an anti-condensation structure for an overturning beam of a refrigerator. The left door body is hinged on the box body, and the right door body is hinged on the box body at the right compartment. An electric heating device is installed in the flip beam, and a flip beam temperature sensor for sensing the surface temperature of the flip beam is embedded on the flip beam surface. The outer wall of the box is provided with an external temperature sensor, and the box is provided with an electric control device and an internal temperature sensor, and the electric control device is connected to the electric heating device, the internal temperature sensor, the flip beam temperature sensor and the external temperature sensor. The invention also discloses the anti-condensation control method, the first step is the start step; the second step is the adjustment step; the third step is the cycle execution step. The invention can not only ensure that no condensation occurs on the overturning beam in most cases, but also prevent waste of energy and realize anti-condensation with low energy consumption.
Description
technical field [0001] The invention relates to the technical field of refrigerators, in particular to the anti-condensation technology of an overturning beam. Background technique [0002] The demand for refrigerators in the consumer market is increasingly multi-functional, and the styles of refrigerators are also varied. One of them is a room with two doors that open left and right, and a flip beam is used between the two doors to prevent cold leakage, but the flip beam If the temperature is too low, it may cause condensation. At present, in order to prevent condensation on the overturning beam, there are two ways to use it in the refrigerator: 1. Determine the start and stop of the heating part of the overturning beam through empirical values, which requires a large amount of test data and consumes more energy; 2. By placing a temperature and humidity sensor, the heating part of the flip beam is controlled to start and stop. This kind of control has high precision and low...
