Description
Technical Field
The invention belongs to the technical field of refrigerator condensation prevention, and particularly relates to a condensation prevention refrigerator and a control method thereof.
Background
Condensation is a phenomenon that when a high-temperature and high-humidity gas encounters a low-temperature object, the gas becomes liquid on the surface thereof when the temperature is equal to or lower than the dew point temperature. The temperature in the refrigerator is far lower than the temperature outside the refrigerator, and the cold in the refrigerator body is outwards diffused through the door seal or the heat insulation layer, so that the surface temperature of the refrigerator body and the door body is lower, and the gas meeting high temperature and high humidity can be condensed into dew on the surface of the refrigerator body and the door body, thereby generating the phenomenon of dew condensation. The condensation phenomenon not only affects the appearance of the refrigerator and the user experience, but also causes corrosion and rust of metal parts and mold and odor of plastic parts for a long time, and the service life of the refrigerator is reduced.
In order to prevent condensation at the joint of two refrigeration door bodies of the conventional refrigeration side-by-side combination refrigerator, a turnover beam is arranged between the two doors, and a heater is arranged on the turnover beam so as to evaporate condensation water condensed on the surface of the refrigerator by utilizing heat emitted by the heater, thereby achieving the effect of condensation prevention. However, in the actual use process, due to the differences of production and assembly of the structural process and the like, the door switch used in the prior art cannot detect the fit clearance between two refrigeration door bodies and the turnover beam and the degree of different faces of two vertical faces, so that the cold air leakage of the box body is different through the door seal between the turnover Liang Yumen bodies, and the required turnover Liang Jia heat is also different. In order to solve the practical use problem, when the control rule of the turnover beam is generally formulated, the heating allowance is given by taking the difference into consideration so as to meet the production requirement. However, a certain energy waste exists in the given heating allowance.
The temperature sensor is arranged on the turnover beam to detect the surface temperature in real time and compare the surface temperature with the dew point temperature, so that the heating quantity of the heater of the turnover beam is accurately controlled, but the position of the temperature sensor, which is not interfered by heating, is difficult to determine due to the arrangement of the heating wires when the sensor is arranged on the turnover beam, and the arrangement of the sensor wire harness on the turnover beam is difficult, so that the process is not well realized.
The invention provides an anti-condensation refrigerator and a control method thereof, wherein the first distance D1 of a left door body and the second distance D2 of a right door body are detected, the distance difference K between the first distance D1 and the second distance D2 is calculated, the heating time of a heater is accurately calculated under the control of heating quantity P=P0+Ph, the condensation can be effectively eliminated, the heat waste is avoided, the resources are saved, and the refrigerator is convenient to install and assemble and disassemble.
