Anti-condensation structure for turnover beam of refrigerator and anti-condensation control method

Abstract

The invention discloses an anti-condensation structure for a turnover beam of a refrigerator and an anti-condensation control method. The anti-condensation structure comprises a box body, wherein a left compartment and a right compartment are arranged on the upper portion of the box body; the turnover beam is arranged between the left compartment and the right compartment; a left door body is hinged to the position, at the left compartment, of the box body; a right door body is hinged to the position, at the right compartment, of the box body; an electric heating device is arranged in the turnover beam; a turnover beam temperature sensor for sensing the surface temperature of the turnover beam is embedded on the surface of the turnover beam; an outer temperature sensor is arranged on the outer wall of the box body; an electric control device and an inner temperature sensor are arranged in the box body; and the electric control device is connected with the electric heating device, the inner temperature sensor, the turnover beam temperature sensor and the outer temperature sensor. The anti-condensation control method comprises the first step of starting; the second step of adjusting;and the third step of loop executing. The anti-condensation structure and the anti-condensation control method can not only guarantee that the phenomenon of condensation of the turnover beam does notappear under most conditions, but also prevent energy from being wasted, and low-energy anti-condensation is realized.

Description

Technical field [0001] The invention relates to the technical field of refrigerators, in particular to the anti-condensation technology of a turning beam. Background technique [0002] The consumer market’s demand for refrigerators is becoming more and more multi-functional, and the styles of refrigerators are also diverse. One of them is a compartment with two left and right doors. The two doors use a flip beam 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 turning beam, the use schemes in the refrigerator are 1. Determine the start and stop of the turning beam heating components through empirical values, which requires a lot of test data and higher energy consumption; 2. By placing a temperature and humidity sensor to control the start and stop of the heating part of the turning beam, this kind of control has high precision, low energy consumption, but high cost. The above...
