Example 1

As shown in fig. 1, fig. 2, fig. 3 and fig. 6, the embodiment provides a side-by-side refrigerator freezing air duct structure for being arranged in a freezing chamber of a refrigerator, for convenience in description, the side-by-side refrigerator is described in the direction of the use state, the left-right direction of the refrigerator is the left-right direction, the up-down direction of the refrigerator when being placed is the vertical direction, the side-by-side refrigerator freezing air duct structure comprises an air duct 10 and a fan 20, the air duct 10 is internally provided with a containing cavity 110, the shape of the air duct 10 can be set to be in various forms, in the embodiment, in order to enable the freezing air duct to be more easily arranged in the refrigerator, the shape of the air duct 10 is set to be a cuboid structure, an air inlet 120 and an air outlet 130 are arranged on the air duct 10, the air inlet 120 is arranged at the bottom of the air duct 10, the air inlet 120 is led to the containing cavity 110 so as to enable cold air to enter the inside the containing cavity 110, the air outlet 130 is arranged at one side of the air duct 10 facing the front, the air outlet 130 is a channel connecting the containing cavity 110 and the cold air, so as to be smoothly entered into the freezing chamber, the bottom of the air duct 10 is provided with the containing cavity 110, the containing cavity, the air duct 10 is provided with the containing cavity, the containing the air inlet is arranged in the containing cavity, the air duct and the air inlet 120 is arranged in the vertical direction opposite to the direction of the vertical direction, and the air evaporator fan is arranged in the air duct 20, and the air inlet is arranged in the vertical direction, and the air evaporator is set up the air direction and is opposite to the air direction of the air evaporator 20.

The working principle of the embodiment is as follows: when the refrigerator starts to operate, the evaporator is started, and simultaneously the fan 20 above the evaporator starts to rotate, and cold air generated by the evaporator is sucked into the air inlet 120 by wind power generated by the rotation of the fan 20 and blown into the accommodating chamber 110. Cold air then enters the freezing chamber through the air outlet 130 to maintain a low temperature state of the freezing chamber. This design effectively circulates cool air to ensure that the food or items within the freezer compartment are maintained at the proper temperature.

The beneficial effects of the freezing wind channel structure of side by side combination refrigerator that this embodiment provided lie in at least: by arranging the freezing air duct structure of the side-by-side combination refrigerator, air in the freezing chamber enters the evaporator to exchange heat and then is sent into the accommodating cavity 110 by the pressure difference generated by the fan 20, and cold air can enter the accommodating cavity 110 and finally enter the freezing chamber through blowing out of the fan 20. This design can enhance circulation and circulation of cold air, thereby improving cooling effect of the freezing chamber. The combination of the rotation of the fan 20 and the air flow enables a wider area of cool air coverage, ensuring that the food or items within the freezer compartment receive cool air evenly. Setting the rotation axis of the fan 20 in the vertical direction can improve the waste caused by the dynamic pressure generated by the fan 20 acting on the inner wall. The rotation axis of the fan 20 is changed to be vertical, which is more beneficial to the wind pressure to act on the evaporator, so that the wind speed around the coil pipe of the evaporator is improved, and the heat exchange efficiency is improved. Thereby reducing the temperature of the freezing air outlet 130, improving the freezing capacity of the compartment, reducing the running frequency and energy consumption of the refrigerating system, being beneficial to reducing energy waste and reducing adverse effect on the environment.

As shown in fig. 4 and 5, in this embodiment, a baffle plate 30 is disposed at an opening of the air outlet 130 facing one side of the accommodating cavity 110, and the baffle plate 30 is a curved baffle plate 30 bent downward, so that cold air enters the freezing chamber along the baffle plate 30. When the cool air blown by the fan 20 enters the accommodating cavity 110 through the air inlet 120, the cool air will encounter the baffle plate 30 at the air outlet 130. The curved shape of the baffle 30 causes the cold air to bend down along the curve and into the freezer compartment along the curve of the baffle 30. By directing the cool air along the arcuate baffle 30 into the freezer compartment, a more uniform distribution of cool air may be achieved. The downward bending design of the arc baffle 30 ensures that the cold air is uniformly dispersed in the freezing chamber, avoids overheating or supercooling in certain areas, and improves the fresh-keeping effect of foods or articles in the freezing chamber. Since the cold air is downwards bent along the baffle 30 to enter the freezing chamber, the baffle 30 can also play a role in buffering and diffusing, so that direct cold air can be prevented from being blown to a specific area, and excessive drying or freezing of food or objects in the freezing chamber can be avoided. The downward curved design of the arcuate baffles 30 also reduces the wind effects of cold air directly on the contents of the receiving chamber 110. If the baffle 30 is a straight plane, cold air may be blown directly toward the articles in the receiving chamber 110 at a high speed, which may result in breakage or quality damage of the articles. While the arcuate baffles 30 may direct the cool air downward and slow down before entering the receiving chamber 110, reducing the wind effects that may be caused to items within the freezer compartment.

As shown in fig. 1, 2 and 3, the air outlet 130 in the present embodiment includes a first air outlet 131, a second air outlet 132 and a third air outlet 133, and the first air outlet 131, the second air outlet 132 and the third air outlet 133 are sequentially disposed at intervals on a side of the air duct 10 facing the front face of the freezing chamber. The first air outlet 131 is disposed at the upper half of the air duct 10, the second air outlet 132 is disposed at the middle of the air duct 10, and the third air outlet 133 is disposed at the lower half of the air duct 10. By providing a plurality of air outlets 130, more uniform distribution of cool air may be achieved. The air outlets 130 at different positions can guide cold air to different areas of the freezing chamber, so that food or articles in the whole freezing chamber can be uniformly cooled. The air outlets 130 are arranged at different positions of the air duct 10, so that excessive concentration of cold air in a certain area can be avoided, and excessive freezing or drying of foods or articles in the area can be avoided. But through the air outlets 130 provided at intervals of the regions, the cool air may be more uniformly distributed in the freezer compartment. The location and spacing of each of the outlets 130 is such that the supply of cool air may be adjusted as desired. The opening degree of each air outlet 130 or the speed of the fan 20 can be adjusted according to the layout or storage mode of foods or articles in the freezing chamber, so as to realize the flexibility of cold air supply in different areas.

As shown in fig. 4 and 5, the baffle 30 in the present embodiment includes a first baffle 310 and a second baffle 320, the first baffle 310 is disposed on a side of the first air outlet 131 facing the accommodating chamber 110, and the second baffle 320 is disposed on a side of the second air outlet 132 facing the accommodating chamber 110. Wherein the area of the first barrier 310 is larger than the area of the second barrier 320. The first baffle 310 and the second baffle 320 are disposed on a side of the respective corresponding air outlets 130 facing the accommodating chamber 110. The provision of the baffle 30 may alter the path and speed of the flow of the cool air, thereby affecting the manner in which the cool air enters the receiving chamber 110. The arrangement of the first baffle 310 and the second baffle 320 may affect the distribution of the cool air. Since the area of the first baffle 310 is larger than that of the second baffle 320, the cool air is more resistant and dispersed when passing through the first baffle 310, and thus a portion of the cool air is more introduced into the second air outlet 132. Due to the arrangement of the area difference, the cold air is subjected to a large resistance and deceleration when passing through the first baffle 310. This may slow down the cool air before entering the receiving cavity 110, thereby reducing direct wind effects that may be caused to frozen foods or items stored within the receiving cavity 110.

As shown in fig. 4 and 5, the baffle 30 in the present embodiment further includes a third baffle 330, where the third baffle 330 is disposed on a side of the third air outlet 133 facing the accommodating cavity 110, and the air outlet amount of the third air outlet 133 is changed by controlling the angle of the third baffle 330 relative to the air duct 10. By adjusting the angle of the third baffle 330, the air output of the third air outlet 133 can be controlled. When the angle of the third baffle 330 is larger, the opening of the air outlet 130 is larger, and the flow rate of cold air is increased; when the angle of the third baffle 330 is smaller, the opening of the air outlet 130 is smaller, and the flow rate of the cool air is reduced. By controlling the air outlet amount of the third air outlet 133, the supply of cool air can be regulated. The amount of cold air supplied can be increased or decreased by adjusting the angle of the third baffle 330 according to the need in the freezer or the change in the ambient temperature to meet different cooling needs.

As shown in fig. 6, in this embodiment, the first baffle 310, the second baffle 320 and the third baffle 330 are all hollow cylindrical structures cut into a quarter, wherein the radius of the cylinder of the second baffle 320 is larger than that of the cylinder of the third baffle 330, the radius of the cylinder of the first baffle 310 is larger than that of the second baffle 320, and since the fan 20 blows in the vertical direction, the cooling air needs to be sequentially led into the freezing chamber through the third baffle 330, the second baffle 320 and the first baffle 310, and the third baffle 320, if the sizes of the plurality of baffles 30 are set to be the same, the air output of the plurality of air outlets 130 is inconsistent, which results in inconsistent temperatures in the freezing chamber of the refrigerator, the air output near the nearest air outlet 130 of the fan 20 is maximum, and the air output 130 is minimum further away from the fan 20, so that the air output of the plurality of air outlets 130 of the freezing chamber is kept consistent by setting the first baffle 310, the second baffle 320 and the third baffle 330 to be sequentially reduced.

As shown in fig. 4, 5 and 6, the structure of the freezing air duct of the side-by-side combination refrigerator in this embodiment further includes a driving assembly, the baffle 30 is connected to the driving assembly, wherein a plurality of driving assemblies are disposed on the air duct, and the first baffle 310, the second baffle 320 and the third baffle 330 are respectively connected to the plurality of driving assemblies and are driven by the driving assemblies to rotate. The drive assembly includes driving motor and drive shaft, and driving motor sets up on wind channel 10, and the one end and the driving motor swing joint of drive shaft, the baffle 30 is connected to the other end. The driving motor and the driving shaft constitute a driving assembly, which functions to transmit a rotational force to the barrier 30 by power of the driving motor. One end of the driving shaft is movably connected with the driving motor, and the other end of the driving shaft is connected with the baffle 30, so that the baffle 30 can be rotated by the operation of the driving motor. By controlling the rotation of the baffle 30, the air output of the air outlet 130 can be adjusted. The drive assembly can adjust the angle of the baffle 30 as needed to vary the flow and speed of the cool air through the air outlet 130. The drive motor is the main part in the drive assembly, and the drive assembly still includes transmission system, control circuit and mechanical connection, and the drive motor is used for providing the turning force. The driving motor can be a direct current motor, an alternating current motor or a stepping motor, and the transmission system structure comprises gear transmission, belt transmission and chain transmission. The control circuitry typically includes motor drivers, sensors, and controllers, among other components. The mechanical connection is used to connect the drive motor to the drive shaft and to connect the drive shaft to the baffle 30. Common mechanical connectors include bearings, couplings, connecting rods, and the like. These connectors serve to support, transmit force and rotate. The driving motor, the transmission system, the control circuit and the mechanical connecting piece work cooperatively, so that the driving assembly can realize the rotation of the baffle 30 through the driving of the driving motor. In this way, the air flow distribution of the freezing air duct can be regulated, so that the temperature of the freezing chamber is controlled.

As shown in fig. 4, 5 and 6, the baffle 30 in the present embodiment further includes a fourth baffle 340, and the fourth baffle 340 is disposed at a side of the third air outlet 133 facing the front surface of the freezing chamber. Because the third air outlet 133 is located closer to the evaporator and the fan 20, a strong flow of cold air may be generated, resulting in excessive cooling of certain areas in the freezing chamber, which has an influence on the quality of frozen foods. The fourth baffle 340 may limit the air output of the third air outlet 133, thereby adjusting the air output distribution of the entire air duct. By limiting the air output of the third air outlet 133, the cold air can be more uniformly distributed in the air duct, and the situation of overcooling or undercooling of the vertical area of the freezing chamber is avoided.

As shown in fig. 1, 4 and 6, the width of the baffle 30 in the present embodiment is equal to the width of the air outlet 130, wherein the width of the first baffle 310 is equal to the width of the first air outlet 131, the width of the second baffle 320 is equal to the width of the second air outlet 132, and the width of the third baffle 330 and the fourth baffle 340 is equal to the width of the third air outlet 133. The width of the baffle 30 is equal to the width of the air outlet 130, so that the baffle 30 can completely cover the corresponding air outlet 130, and the design of width matching enables the baffle 30 to effectively control the opening size and angle of the air outlet 130. To adjust and equalize the temperature profile of the freezer compartment. The matching of the width of the baffle 30 and the width of the air outlet 130 ensures that the control of the baffle 30 can accurately influence the distribution and supply of cold air, thereby realizing the adjustment and equalization of temperature.

As shown in fig. 1, the freezing air duct structure of the side-by-side refrigerator in this embodiment further includes a refrigerating air outlet 140, where the refrigerating air outlet 140 is disposed on the air duct 10 and is used for transferring part of the cold air in the air duct 10 into the refrigerating compartment. The refrigeration outlet 140 is located above or to the side of the air duct 10 within the freezer compartment. Through the passage of the freezing duct, cold air may enter the refrigerating compartment from within the freezing compartment through the refrigerating outlet 140. The refrigerating outlet 140 transfers part of the cool air from the air duct to the refrigerating compartment. This ensures that the temperature in the refrigerated compartment is maintained in a suitable range, maintaining the freshness and quality of the food. The refrigerating outlet 140 can prevent the cold air in the refrigerating chamber from excessively accumulating, and avoid the excessive temperature. By moving part of the cool air to the refrigerating compartment, it is possible to avoid a temperature rise in the freezing compartment, maintaining the freshness and quality of the food.

As shown in fig. 1, the freezing air duct structure of the side-by-side refrigerator in this embodiment further includes a defrosting heater and a temperature sensor, where the temperature sensor is disposed in the freezing chamber and is used for detecting the temperature in the freezing chamber at regular time, so as to control the rotation angle of the baffle 30 in time, to adjust the air volume of the air outlet 130, and the temperature sensor can measure the temperature by using the principles of a thermistor, a thermocouple or a semiconductor, etc., and generate an electrical signal or a resistance change by using the temperature characteristic of the material, thereby reflecting the temperature change. The data from the temperature sensor can be used for feedback from the control system to adjust the angle of rotation of the baffle 30 in time. When the temperature of the freezing chamber exceeds the set upper limit temperature, the control system opens the baffle 30 accordingly to increase the air volume of the air outlet 130 to increase the cold air supply. Conversely, when the temperature is lower than the set lower limit temperature, the control system will close or reduce the opening degree of the baffle 30 accordingly, and reduce the air volume of the air outlet 130. The defrosting heater is provided at the bottom of the evaporator and is used for defrosting the evaporator as well as the fan 20. Defrosting heaters typically take the form of electric heaters that provide a heating effect by converting electrical energy into thermal energy. The heater is typically composed of a heating element such as a resistance wire or an electric heating tube, and generates heat by passing an electric current through the heating element. During the freezing process, the evaporator surface may freeze, forming a layer of frost and ice. The frost ice may negatively affect the heat transfer efficiency of the condenser, reducing the freezing effect. The defrosting heater is used for applying heat to the evaporator to melt the frost ice into water, so that the surface of the evaporator is kept clean and the heat transfer efficiency is kept. When the defrosting heater is operated, in order to prevent the heat generated by the heater from affecting the temperature in the freezing chamber, the baffle 30 is in a closed state, so that the temperature in the freezing chamber is prevented from being excessively affected.

In a second aspect, the present application provides a damper control method including:

s100, detecting the temperature in the refrigerating chamber at fixed time through a sensor.

In a specific process, the damper control method first needs to detect the temperature in the freezer. By installing a temperature sensor or other temperature detecting device, the temperature change of the freezing chamber can be monitored in real time. These temperature sensors may transmit temperature signals to the control system for subsequent damper control and regulation.

And S200, adjusting the rotation angle of the baffle according to the measured temperature of the freezing chamber.

In a specific process, according to the temperature change in the refrigerating chamber, the control system can control the opening and closing degree of the air door by adjusting the rotation angle of the baffle 30. When the temperature in the freezing chamber is high, the control system will open the baffle 30 to increase the air output of the air outlet 130, so as to increase the supply of cold air into the freezing chamber. Conversely, when the temperature in the freezing chamber is low, the control system can close the third baffle 330 or reduce the opening degree, and reduce the air output of the air outlet 130, so as to reduce the supply of cold air into the freezing chamber.

And S210, when the refrigerator is in a refrigerating cycle, the refrigerating air outlet is in an open state, and the rotation angles of the first baffle, the second baffle and the third baffle are reduced according to the temperature of the refrigerating chamber.

In a specific process, when the refrigerator is in a refrigeration cycle, the refrigeration air outlet 140 is in an opened state, and by adjusting the rotation angles of the first baffle 310, the second baffle 320 and the third baffle 330, the air quantity of the cold air flowing into the first air outlet 131, the second air outlet 132 and the third air outlet 133 is reduced, and most of the cold air moves towards the refrigeration air outlet 140, so that the air quantity of the refrigeration compartment can be increased.

S220, when the refrigerator is in a defrosting state, the first baffle, the second baffle and the third baffle are closed.

In a specific process, when the refrigerator is in a defrosting state, the temperature in the air duct is increased, and in order not to influence the temperature in the freezing chamber and influence the freezing effect of food, the first baffle 310, the second baffle 320 and the third baffle 330 are closed to reduce the influence of the heater on the temperature of the freezing chamber.

It is to be understood that the invention is not limited in its application to the examples described above, but is capable of modification and variation in light of the above teachings by those skilled in the art, and that all such modifications and variations are intended to be included within the scope of the appended claims.
