[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0025] The two door bodies of a double-door refrigerator are closed through a flipping beam structure to solve the problem of cold leakage. However, at the same time, due to the poor heat preservation effect at the flipping beam, condensation often occurs, bringing a bad experience to users. In order to solve the problem of condensation on the flipping beam of the refrigerator, in the prior art, a heating wire is usually set to increase the surface temperature of the flipping beam and reduce the risk of condensation on the flipping beam. However, the heating wires set in the prior art are all set in a whole section and operate at a fixed power-on rate, without considering the problem of uneven temperature distribution in the refrigerating / freezing compartment of the refrigerator, nor can it solve the problem of condensation on the flipping beam under different working conditions, resulting in poor anti-condensation effect of the flipping beam.

[0026] Therefore, in order to solve the technical problem of poor anti-condensation effect of the flipping beam in the prior art, the present invention proposes a control method for a flipping beam heater, which specifically includes the steps of:

[0027] Set a relationship comparison table between the dew point temperature and the preset on-off rate;

[0028] Obtain the dew point temperature corresponding to the current environment, turn on the heating elements in each heating area of the flipping beam heater, and the on-off rate of the heating elements is the preset on-off rate corresponding to the current dew point temperature;

[0029] After the heating elements are heated for a preset duration, obtain the surface temperature of the flipping beam corresponding to each heating area, and determine whether the lowest surface temperature is less than or equal to the current dew point temperature;

[0030] If so, adjust the on-off rate of the heating elements in the heating area with the lowest surface temperature and the surface temperature less than or equal to the current dew point temperature to prevent condensation, and then return to the previous step.

[0031] It can be seen from this that the control method of the flipping beam heater proposed by the present invention is to provide a plurality of heating elements on the flipping beam, each heating element can be independently controlled, and the on-off rate of each heating element can be adjusted according to the dew point temperature of the environment. Therefore, the control method of the flipping beam heater proposed by the present invention can solve the problem of condensation on the flipping beam under different working conditions and has a good anti-condensation effect.

[0032] The principle and structure of the present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] First of all, the flipping beam heater mentioned in the control method of the flipping beam heater proposed by the present invention includes: a plurality of heating elements provided on the condensation side of the flipping beam and a temperature sensor for obtaining the surface temperature of the flipping beam. Among them, a plurality of heating areas are sequentially arranged along the length direction of the flipping beam, and each heating area is provided with a heating element and a temperature sensor. The heating elements in each heating area are independently controlled, and the on-off rate of the heating elements in each heating area can be adjusted.

[0034] Specifically, as Figure 1 shown, in this embodiment, a first heating area, a second heating area and a third heating area are sequentially arranged along the length direction of the flipping beam 1. Among them, the first heating area and the third heating area are arranged at both ends of the flipping beam, the second heating area is arranged in the middle section of the flipping beam, the first heating area is provided with a first heating element 2 and a first temperature sensor 5, the second heating area is provided with a second heating element 3 and a second temperature sensor 6, and the third heating area is provided with a third heating element 4 and a third temperature sensor 7. Among them, the first heating element, the second heating element and the third heating element are all heating wires wound into a disc shape, the first heating element, the second heating element and the third heating element are attached to the flipping beam, and the first heating element, the second heating element and the third heating element are connected in parallel.

[0035] Based on the above flipping beam heater, as Figure 2 shown, the present invention proposes a control method for a flipping beam heater, which specifically includes the steps of:

[0036] Set a relationship comparison table between the dew point temperature and the preset on-off rate;

[0037] Obtain the dew point temperature corresponding to the current environment, turn on the heating elements in each heating area, and the on-off rate of the heating elements is the preset on-off rate corresponding to the current dew point temperature;

[0038] After the heating element heats for a preset duration, obtain the surface temperature of the flipping beam corresponding to each heating area, and judge whether the lowest surface temperature is less than or equal to the current dew point temperature;

[0039] If so, increase the on-off rate of the heating elements in the heating zone where the surface temperature is the lowest and the surface temperature is less than or equal to the current dew point temperature by a preset on-off value, and then return to the previous step;

[0040] If not, keep the on-off rates of the heating elements in each heating zone unchanged, and then return to the step of obtaining the dew point temperature corresponding to the current environment.

[0041] Next, taking the flip beam heater with the first heating zone, the second heating zone and the third heating zone proposed above as an example and combining with Figure 3 the control method proposed by the present invention will be further explained.

[0042] First, simulate multiple times the effect of preventing condensation on the flip beam when the heating elements are heated at different on-off rates at a certain dew point temperature, so as to select the on-off rate that consumes the least power but can prevent condensation on the flip beam at the current dew point temperature as the preset on-off rate corresponding to the current dew point temperature. The on-off rate refers to the ratio of the power-on time in a unit cycle. After that, change the dew point temperature and repeat the above experimental operations to obtain a relationship comparison table between the dew point temperature and the preset on-off rate.

[0043] Then, obtain the ambient temperature and ambient humidity of the current environment, and then obtain the current dew point temperature T0 according to the ambient temperature and ambient humidity. After obtaining the current dew point temperature T0, turn on the first heating element in the first heating zone, the second heating element in the second heating zone and the third heating element in the third heating zone. The on-off rates of the first heating element, the second heating element and the third heating element are the preset on-off rates corresponding to the current dew point temperature.

[0044] After the first heating element, the second heating element and the third heating element are heated for a preset duration at the preset on-off rate corresponding to the current dew point temperature, the first temperature sensor obtains the surface temperature T1 of the flip beam where the first heating zone is located, the second temperature sensor obtains the surface temperature T2 of the flip beam where the second heating zone is located, and the third temperature sensor obtains the surface temperature T3 of the flip beam where the third heating zone is located. Then, judge whether the minimum value among the surface temperature obtained by the first temperature sensor, the surface temperature obtained by the second temperature sensor and the surface temperature obtained by the third temperature sensor is less than or equal to the current dew point temperature T0;

[0045] If the lowest surface temperature is less than or equal to the current dew point temperature T0, increase the on-off rate of the corresponding heating element by a preset on-off value, and then return to the previous step. That is, if the surface temperature T1 of the flipping beam detected by the first temperature sensor is the minimum and less than or equal to the current dew point temperature T0, increase the on-off rate of the first heating element by a preset on-off value. Then, return to the previous step to re-obtain the surface temperatures of the first heating area, the second heating area, and the third heating area, and increase the on-off rate of the heating element in the heating area corresponding to the lowest surface temperature and less than or equal to the current dew point temperature T0 by a preset on-off rate. Repeat this step until the surface temperatures of all heating areas are greater than the current dew point temperature T0. If the surface temperature T2 of the flipping beam detected by the second temperature sensor is the minimum and less than or equal to the current dew point temperature T0, increase the on-off rate of the second heating element by a preset on-off value. Then, return to the previous step to re-obtain the surface temperatures of the first heating area, the second heating area, and the third heating area, and increase the on-off rate of the heating element in the heating area corresponding to the lowest surface temperature and less than or equal to the current dew point temperature T0 by a preset on-off rate. Repeat this step until the surface temperatures of all heating areas are greater than the current dew point temperature T0. If the surface temperature T3 of the flipping beam detected by the third temperature sensor is the minimum and less than or equal to the current dew point temperature T0, increase the on-off rate of the third heating element by a preset on-off value. Then, return to the previous step to re-obtain the surface temperatures of the first heating area, the second heating area, and the third heating area, and increase the on-off rate of the heating element in the heating area corresponding to the lowest surface temperature and less than or equal to the current dew point temperature T0 by a preset on-off rate. Repeat this step until the surface temperatures of all heating areas are greater than the current dew point temperature T0.

[0046] If the lowest surface temperature is greater than the current dew point temperature T0, keep the on-off rates of the first heating element, the second heating element, and the third heating element unchanged, and then return to the step of obtaining the dew point temperature corresponding to the current environment.

[0047] In the control method proposed in the present invention, the on-off rates of the heating elements in all heating areas with surface temperatures lower than the current dew point temperature are not increased simultaneously to raise the temperatures of all heating areas with surface temperatures lower than the current dew point temperature and prevent condensation. Instead, only the heating element in the heating area corresponding to the lowest surface temperature and less than or equal to the current dew point temperature is adjusted each time. This is because when adjusting the heating element in one heating area, due to heat transfer, the surface temperature of the heating area adjacent to this heating area will rise and may rise to a state greater than or equal to the current dew point temperature. Therefore, adjusting only one heating area at a time is conducive to saving energy and reducing energy consumption.

[0048] In summary, the control method of the flip beam heater proposed by the present invention can adjust the on-off rate of the flip beam heater according to the changes in the environment, thereby solving the problem of condensation on the flip beam under different working conditions.

[0049] The present invention also proposes a refrigerator, which is a double-door refrigerator. There is a flip beam on the door body of the refrigerator. There are multiple heating elements and multiple temperature sensors for obtaining the surface temperature of the flip beam on the condensation side of the flip beam. Among them, multiple heating areas are arranged in sequence along the length direction of the flip beam, and each heating area is provided with a heating element and a temperature sensor. The heating elements in each heating area are independently controlled, and the on-off rate of the heating elements in each heating area can be adjusted.

[0050] Further, the flip beam of the refrigerator prevents condensation through the control method proposed above, specifically including the steps:

[0051] Set a relationship comparison table between the dew point temperature and the preset on-off rate;

[0052] Obtain the dew point temperature corresponding to the current environment, turn on the heating elements in each heating area, and the on-off rate of the heating elements is the preset on-off rate corresponding to the current dew point temperature;

[0053] After the heating elements are heated for a preset duration, obtain the surface temperature of the flip beam corresponding to each heating area, and determine whether the lowest surface temperature is less than or equal to the current dew point temperature;

[0054] If so, increase the on-off rate of the heating element in the heating area with the lowest surface temperature and less than or equal to the current dew point temperature by a preset on-off value, and then return to the previous step;

[0055] If not, keep the on-off rate of the heating elements in each heating area unchanged, and then return to the step of obtaining the dew point temperature corresponding to the current environment.

[0056] The present invention also proposes a computer storage medium, which stores one or more instructions, and the one or more instructions are suitable for being loaded and executed by a processor to perform the control method of the flip beam heater above.
