Specifically, the refrigeration process of the air-cooled refrigerator is as follows: the refrigeration evaporator generates cold, the refrigeration evaporator performs air circulation to refrigerate the freezing chamber, the refrigeration evaporator can pump the cold generated by the refrigeration evaporator upwards, the cold is delivered to the upper part of the refrigeration air channel through the air supply outlet, the air supply pipe and the air door after the air door is opened, and finally the cold reaches the refrigerating chamber through the air outlet to refrigerate the refrigerating chamber. However, because the temperature difference between the refrigerating chamber and the freezing chamber is large, when moisture in the chamber enters the air-cooled refrigerator, the air supply opening for communicating the freezing chamber and the refrigerating chamber is frozen under the combined action of cold air and moisture. Along with the accumulation of the ice, the transmission channel of the cold energy is blocked, the cold energy generated by the freezing evaporator cannot be transmitted to the refrigerating chamber, so that the refrigerating chamber is not refrigerated, and the food stored in the refrigerating chamber is overdue. In order to solve the problem that the refrigerating chamber is not refrigerated due to the fact that the air supply opening is frozen, the heating wire can be additionally arranged on the outer side of the air supply pipe, and therefore the air-cooled refrigerator can heat the air supply pipe through the heating wire to prevent the air supply opening from being frozen.

The memory 12 may be self-contained and coupled to the processor 11 via a communication bus 14. The memory 12 may also be integrated with the processor 11.

In a specific implementation, the memory 12 is used for storing data in the present application and executing software programs of the present application.

In order to solve the problem that the energy consumption of the air-cooled refrigerator is increased because the air supply opening is not frozen and the heating wire still works, the embodiment of the application provides a control method of the heater. Specifically, as shown in fig. 3, the method may include the following steps 201 to 203:

201. the refrigerator obtains a first temperature value and a second temperature value when the freezing and evaporating fan rotates.

Wherein the first temperature value represents a temperature in the blast pipe, and the second temperature value represents a temperature in an upper portion of the freezing evaporator. The relation between the first temperature value and the second temperature value obtained by the refrigerator can indicate whether the air supply outlet is frozen or not only when the freezing and evaporating fan rotates to pump the cold from the freezing chamber to the refrigerating chamber. Therefore, the refrigerator can acquire a first temperature value of a first sensor arranged between the air door and the air supply outlet and a second temperature value of a second sensor arranged on the freezing evaporator when the freezing evaporation fan rotates.

202. The refrigerator calculates a difference between the first temperature value and the second temperature value.

203. And if the difference value is larger than the preset value, controlling the heater to start working.

The refrigerating system comprises a refrigerating chamber, an air door, a refrigerating air duct, a first temperature value, a second temperature value, a refrigerating air duct and a refrigerating air duct, wherein the refrigerating air duct is connected with the refrigerating chamber through the air door, the refrigerating air duct and the refrigerating air duct. However, as time goes on, the freezing of the air supply outlet gradually increases, so that the transmission effect of the cooling capacity gradually becomes worse, and the difference between the first temperature value and the second temperature value gradually increases, and therefore the refrigerator can judge whether the difference is larger than the preset value after calculating the difference between the first temperature value and the second temperature value. If the difference is larger than the preset value, the condition that the air supply outlet is blocked by ice is indicated, and the refrigerator can control the heater to start working at the moment. If the difference is smaller than or equal to the preset value, the condition that the air supply outlet is not blocked by ice is indicated, and the refrigerator does not need to control the heater to start working.

In a possible implementation manner, after the refrigerator controls the heater to start operating for a preset time, the step 201 and the step 202 may be periodically executed, and it is determined whether a difference between the first temperature value and the second temperature value obtained again is greater than a preset value, if the difference between the first temperature value and the second temperature value obtained again is still greater than the preset value, the refrigerator may control the heater to continue operating, and if the difference is less than or equal to the preset value, the refrigerator may control the heater to stop operating. In another possible implementation manner, after the refrigerator controls the heater to start to operate for a preset time, the heater may be controlled to stop operating, step 201 and step 202 are executed, whether a difference value between the first temperature value and the second temperature value obtained again is greater than a preset value is judged, if the difference value is greater than the preset value, the heater is controlled to continue to operate, and after the preset time, the judgment is continued until the difference value between the first temperature value and the second temperature value obtained again is less than or equal to the preset value, and if the difference value is less than or equal to the preset value, the heater does not need to be controlled to continue to operate.

It should be noted that, in the embodiment of the present application, since the first temperature value and the second temperature value have a certain difference value under the condition that the air feeding port is not frozen, but belong to a normal range, it can be determined that the air feeding port is blocked by ice only if the difference value is large to a certain extent, and in a specific implementation, the preset value can be obtained according to an actual situation and is configured in a refrigerator in advance.

In addition, the heater may be specifically a heating wire or a heating sheet, and the specific form of the heater is not limited herein in the embodiments of the present application.
