[0002] Currently, most refrigerators on the market have double-door frost-free compartments, such as French door refrigerators, where the refrigerator compartment consists of two doors that open from the left and right. Generally, a hinged beam is installed on the side of one of the doors to overlap with the other door, ensuring a tight seal when the refrigerator compartment is closed.
[0003] Because the tilting beam itself has poor thermal insulation performance, it is necessary to install heaters on the inner surface of the tilting beam for temperature compensation to prevent condensation from appearing on the surface of the tilting beam.
[0004] Generally speaking, the heater inside the tilting beam operates more frequently as ambient temperature and humidity increase. While existing heating control methods can prevent condensation on the tilting beam surface, the heater consumes a significant amount of electricity, resulting in excessive overall power consumption for the refrigerator and weakening its competitive advantage in the market.

[0042] The present invention provides a preferred embodiment of a refrigerator control method, applicable to frost-free refrigerators with double doors in the refrigerator compartment.
[0043] See Figure 1 -3. The refrigerator's crisper compartment has a first door and a second door that open from the left and right. A flip beam 1 is located on the side of the first door for overlapping with the second door. Inside the flip beam 1 are a first heating element 11 located at the top and a second heating element 12 located at the bottom. Specifically, the first heating element 11 and the second heating element 12 are installed on the inner surface of the flip beam 1. The first heating element 11 and the second heating element 12 can be turned on or off simultaneously, or at different times. A temperature sensor 3 is installed inside the crisper compartment. The temperature sensor 3 is generally located in the air duct of the crisper compartment or on the side of the inner liner, and its function is to detect the temperature inside the crisper compartment. A temperature and humidity sensor 2 is installed on the top of the refrigerator, and its function is to detect the temperature and humidity of the external environment in which the refrigerator is located. The temperature and humidity sensor 2, located on the top of the refrigerator, can more accurately sense the temperature and humidity of the external environment.
[0044] See Figure 4 , Figure 4 This is a flowchart of a preferred embodiment of a refrigerator control method, including steps S1-S4:
[0045] Step S1: Obtain the cumulative cooling time of the refrigerator and determine whether it meets the first preset condition. The first preset condition may be: the cumulative cooling time of the refrigerator is greater than or equal to 6 hours.
[0046] Step S2: When the first preset condition is met, the temperature of the refrigerator compartment measured by the temperature sensor 3 and the ambient temperature and humidity b measured by the temperature and humidity sensor 2 are obtained in real time. The difference between the refrigerator compartment temperature and the ambient temperature is recorded as a.
[0047] Step S3: Determine the heating start-up rate based on the refrigerator compartment temperature, the ambient temperature, and the ambient humidity b. In practice, the heating start-up rate is determined based on the difference between the refrigerator compartment temperature and the ambient temperature (a) and the ambient humidity (b). Here, the "heating start-up rate" is the ratio of the heater's running time to the total time of the heater's operation and shutdown, i.e., heating start-up rate = heater running time / (heater running time + heater shutdown time). In actual settings, the heater shutdown time is generally set first, and then the heater's running time is determined by the heating start-up rate. For example, if the heater shutdown time is set to 2 minutes, the heater's running time is 2 minutes when the heating start-up rate is 50%. Preferably, the heating start-up rates corresponding to the difference between the refrigerator compartment temperature and the ambient temperature (a) and the ambient humidity (b) are shown in Table 1 below:
[0048]
[0049] Table 1
[0050] According to Table 1, when 0℃ < a ≤ 10℃ and b ≥ 90%, the heating start-up rate is 60%; when 0℃ < a ≤ 10℃ and 90% > b ≥ 70%, the heating start-up rate is 40%; when 0℃ < a ≤ 10℃ and 70% > b ≥ 50%, the heating start-up rate is 25%; when 0℃ < a ≤ 10℃ and 50% > b ≥ 30%, the heating start-up rate is 10%; when 0℃ < a ≤ 10℃ and 30% > b ≥ 10%, the heating start-up rate is 2%; and when 0℃ < a ≤ 10℃ and 10% > b, the heating start-up rate is 0%. When 10℃ < a ≤ 20℃ and b ≥ 90%, the heating start-up rate is 60%; when 10℃ < a ≤ 20℃ and 90% > b ≥ 70%, the heating start-up rate is 40%; when 10℃ < a ≤ 20℃ and 70% > b ≥ 50%, the heating start-up rate is 30%; when 10℃ < a ≤ 20℃ and 50% > b ≥ 30%, the heating start-up rate is 15%; when 10℃ < a ≤ 20℃ and 30% > b ≥ 10%, the heating start-up rate is 5%; when 10℃ < a ≤ 20℃ and 10% > b, the heating start-up rate is 0%. When 20℃ < a ≤ 30℃ and b ≥ 90%, the heating start-up rate is 65%; when 20℃ < a ≤ 30℃ and 90% > b ≥ 70%, the heating start-up rate is 45%; when 20℃ < a ≤ 30℃ and 70% > b ≥ 50%, the heating start-up rate is 35%; when 20℃ < a ≤ 30℃ and 50% > b ≥ 30%, the heating start-up rate is 15%; when 20℃ < a ≤ 30℃ and 30% > b ≥ 10%, the heating start-up rate is 5%; when 20℃ < a ≤ 30℃ and 10% > b, the heating start-up rate is 0%. When 30℃ < a ≤ 40℃ and b ≥ 90%, the heating start-up rate is 70%; when 30℃ < a ≤ 40℃ and 90% > b ≥ 70%, the heating start-up rate is 50%; when 30℃ < a ≤ 40℃ and 70% > b ≥ 50%, the heating start-up rate is 35%; when 30℃ < a ≤ 40℃ and 50% > b ≥ 30%, the heating start-up rate is 20%; when 30℃ < a ≤ 40℃ and 30% > b ≥ 10%, the heating start-up rate is 5%; when 30℃ < a ≤ 40℃ and 10% > b, the heating start-up rate is 0%. When 40℃ < a ≤ 50℃ and b ≥ 90%, the heating start-up rate is 80%; when 40℃ < a ≤ 50℃ and 90% > b ≥ 70%, the heating start-up rate is 60%; when 40℃ < a ≤ 50℃ and 70% > b ≥ 50%, the heating start-up rate is 40%; when 40℃ < a ≤ 50℃ and 50% > b ≥ 30%, the heating start-up rate is 25%; when 40℃ < a ≤ 50℃ and 30% > b ≥ 10%, the heating start-up rate is 10%; when 40℃ < a ≤ 50℃ and 10% > b, the heating start-up rate is 2%.
[0051] Step S4: Obtain the refrigeration status of the refrigerator compartment. When the refrigerator compartment is in a refrigeration state, execute the first heating program; when the refrigerator compartment is not in a refrigeration state, execute the second heating program.
[0052] In some embodiments of this application, the first heating procedure is as follows: the first heating element 11 operates for a first preset duration according to the heating start-up rate, while the second heating element 12 does not operate. For example, when the heater shutdown time is set to 2 minutes, and the heating start-up rate is calculated to be 50% in step S3, the first preset duration is 2 minutes. That is, in this embodiment, the first heating element 11 operates for 2 minutes.
[0053] In some embodiments of this application, the first heating procedure is as follows: the first heating element 11 operates for a first preset duration according to the heating start-up rate, and the second heating element 12 operates for a second preset duration, wherein the second preset duration is less than the first preset duration. Preferably, the ratio of the second preset duration to the first preset duration is between 0.2 and 0.4. Most preferably, the ratio of the second preset duration to the first preset duration is 0.3, that is, the operating duration of the second heating element 12 is 30% of the operating duration of the first heating element 11. For example, when the heater shutdown time is set to 2 minutes, and the heating start-up rate is calculated to be 50% in step S3, the first preset duration is 2 minutes, and the second preset duration is between 24 and 48 seconds. That is, in this embodiment, the first heating element 11 operates for 2 minutes, and the second heating element 12 operates for 24 to 48 seconds.
[0054] When the refrigerator compartment is in cooling mode, the upper half of the tilting beam 1 is colder than the lower half, and condensation easily forms on the surface of the upper half. Therefore, the first heating element 11 must be activated to prevent condensation from forming on the surface of the upper half of the tilting beam 1. This is because the air duct outlets of a refrigerator are generally located at the top of the cooling compartment. When the refrigerator compartment is cooling, a top-down circulation of cooling air is formed (e.g., ...). Figure 1 (As shown). Due to the direct blowing of cold air, the upper part of the refrigerator compartment is colder than the lower part, resulting in the upper part of the tilting beam 1 being colder than the lower part. Therefore, when the refrigerator compartment is in cooling mode, the first heating element 11 needs to operate to prevent condensation from forming on the surface of the upper part of the tilting beam 1. The second heating element 12 can have two states: the first is not operating, which can save heating energy to the maximum extent; the second is operating, but the operating time is about 30% of the operating time of the first heating element 11, thereby ensuring that no condensation forms on the surface of the entire tilting beam 1, while saving heating energy.
[0055] In some embodiments of this application, the second heating procedure is as follows: the second heating element 12 runs for a third preset duration according to the heating start-up rate, while the first heating element 11 does not run. For example, when the heater shutdown time is set to 2 minutes, and the heating start-up rate is calculated to be 50% in step S3, the third preset duration is 2 minutes. That is, in this embodiment, the second heating element 12 runs for 2 minutes.
[0056] In some embodiments of this application, the second heating program is as follows: the second heating element 12 operates for a third preset duration according to the heating start-up rate, and the first heating element 11 operates for a fourth preset duration, wherein the fourth preset duration is less than the third preset duration. Preferably, the ratio of the fourth preset duration to the third preset duration is between 0.2 and 0.4. Most preferably, the ratio of the fourth preset duration to the third preset duration is 0.3, that is, the operating duration of the first heating element 11 is 30% of the operating duration of the second heating element 12. For example, when the heater shutdown time is set to 2 minutes, and the heating start-up rate is calculated to be 50% in step S3, the third preset duration is 2 minutes, and the fourth preset duration is between 24 and 48 seconds. That is, in this embodiment, the second heating element 12 operates for 2 minutes, and the first heating element 11 operates for 24-48 seconds.
[0057] When the refrigerator compartment is not cooling, the upper half of the tilting beam 1 is warmer than the lower half, and condensation easily forms on the surface of the lower half. Therefore, the second heating element 12 must operate to prevent condensation on the lower half of the tilting beam 1. This is because when the refrigerator compartment is not cooling, the air inside stops circulating, and the cold air naturally sinks, causing the upper half of the refrigerator compartment to be warmer than the lower half, resulting in the upper half of the tilting beam 1 being warmer than the lower half. Therefore, when the refrigerator compartment is not cooling, the second heating element 12 needs to operate to prevent condensation on the lower half of the tilting beam 1. The first heating element 11 can have two states: one is not operating, which maximizes energy savings; the other is operating, but for approximately 30% of the operating time of the second heating element 12, thus ensuring that condensation does not form on the entire surface of the tilting beam 1 while saving energy.
[0058] See Figure 5This is a control logic diagram of a preferred embodiment of the refrigerator control method provided by the present invention. In this embodiment, the cumulative cooling time of the refrigerator is first obtained, and it is determined whether it is greater than or equal to 6 hours. After the refrigerator has been powered on for 6 hours of cooling, the refrigerator compartment temperature measured by the temperature sensor 3 and the ambient temperature and humidity b measured by the temperature and humidity sensor 2 are collected (acquired in real time) to determine the heating start-up rate corresponding to the difference 'a' between the refrigerator compartment temperature and the ambient temperature and the ambient humidity b. The cooling state of the refrigerator compartment is also obtained. When the refrigerator compartment is in the cooling state, the first heating element 11 is controlled to run for a first preset time according to the heating start-up rate, and the second heating element 12 is not running; when the refrigerator compartment is in the non-cooling state, the second heating element 12 is controlled to run for a third preset time according to the heating start-up rate, and the first heating element 11 is not running.

The one or more modules / units can be a series of computer program instruction segments capable of performing specific functions, and the instruction segments are used to describe the execution process of the computer program in the refrigerator.
