Description

Technical Field

[0001] The present application relates to the technical field of refrigeration equipment, for example, to a refrigerator. Background Art

[0002] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. In recent years, with the continuous improvement of people's living standards, people's pursuit of living quality and food quality has become higher and higher. When it comes to choosing a household refrigerator, people's demand for large-capacity, frost-free, energy-saving, silent, and intelligent refrigerators has gradually increased, and the application of double-door refrigerators has become more and more widespread.

[0003] The related technology discloses a double-door refrigerator, comprising a first inner tank having a freezing compartment and a second inner tank having a refrigerating compartment, an evaporator is provided at the bottom of the first inner tank, an air duct is provided between the back plate of the first inner tank and the air duct plate, and the air duct is connected to the refrigerating compartment through a branch air duct, an air door is provided on the branch air duct, and the air duct is connected to the freezing compartment through an air outlet on the air duct plate, wherein a fan is provided in the air duct, and when the air door is opened, the fan rotates to drive a low-temperature air flow to flow to the refrigerating compartment and the freezing compartment.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] The side-by-side refrigerator in the related art is a single-system refrigeration system. During operation, air flows through the evaporator to form a low-temperature airflow, which flows upward to the fan and flows into the refrigerated compartment and the freezer compartment at the same time under the drive of the fan. However, when the return air from the refrigerated compartment is transported to the vicinity of the evaporator, driven by the strong power of the fan, part of the airflow will flow directly to the fan without passing through the evaporator and enter the freezer compartment. This will increase the temperature of the airflow entering the freezer compartment, increase the refrigeration capacity required for the freezer compartment, and cause energy waste.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field.

[0040] A refrigerator is a refrigeration device that keeps a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature. In recent years, with the continuous improvement of people's living standards, people's pursuit of living quality and food quality has become higher and higher. When it comes to choosing a household refrigerator, people's demand for large-capacity, frost-free, energy-saving, silent, and intelligent refrigerators has gradually increased, and the application of double-door refrigerators has become more and more widespread.

[0041] The related technology discloses a double-door refrigerator, comprising a first inner tank having a freezing compartment and a second inner tank having a refrigerating compartment, an evaporator is provided at the bottom of the first inner tank, an air duct is provided between the back plate of the first inner tank and the air duct plate, and the air duct is connected to the refrigerating compartment through a branch air duct, an air door is provided on the branch air duct, and the air duct is connected to the freezing compartment through an air outlet on the air duct plate, wherein a fan is provided in the air duct, and when the air door is opened, the fan rotates to drive a low-temperature air flow to flow to the refrigerating compartment and the freezing compartment.

[0042] However, the side-by-side refrigerator in the related art is a single-system refrigeration system. During operation, air flows through the evaporator to form a low-temperature airflow, which flows upward to the fan and flows into the refrigerated compartment and the freezer compartment at the same time under the drive of the fan. However, when the return air from the refrigerated compartment is transported to the vicinity of the evaporator, driven by the strong power of the fan, part of the airflow will flow directly to the fan without passing through the evaporator and enter the freezer compartment. This will increase the temperature of the airflow entering the freezer compartment, increase the refrigeration capacity required for the freezer compartment, and cause energy waste.

By making the first fan and the second fan operate alternately, that is, the second fan stops operating when the first fan is operating, so that the return airflow of the refrigerating chamber can be avoided from directly flowing into the freezing chamber without passing through the evaporator, thereby ensuring the airflow temperature entering the freezing chamber, keeping the refrigerating capacity of the freezing chamber stable, thereby reducing energy consumption and improving refrigeration efficiency.

[0052] In addition, by stopping the second fan when the first fan is running, or stopping the first fan when the second fan is running, it is possible to prevent the airflow in the refrigerating compartment from entering the freezing compartment, or prevent the airflow in the freezing compartment from entering the refrigerating compartment, thereby preventing the airflow from mixing with each other, and further preventing the odors in the refrigerating compartment and the freezing compartment from mixing with each other, thereby improving the storage quality of food in the refrigerator.

[0053] Optionally, the partition plate 400 is configured as an arc-shaped plate. By configuring the partition plate 400 as an arc-shaped plate, it is possible to avoid the occurrence of a flow dead angle in the refrigeration air supply duct 231 or the freezing air supply duct 232, thereby ensuring the smooth flow of the low-temperature airflow.

[0054] Optionally, the first fan 310 includes a first shell 311 connected between the second air duct plate 210 and the air duct cover 220; one end of the partition plate 400 is fixedly connected to the first shell 311, and the other end of the partition plate 400 extends toward the bottom end of the refrigeration air duct 230 and is fixedly connected to the first side plate 221 or the bottom plate of the air duct cover 220; wherein the first shell 311 is fixedly connected to the first side plate 221.
