Fig. 1 is a schematic structural view of an air-cooled refrigerator 100 according to an embodiment of the present invention, fig. 2 is a front view of an inner container 111 of the air-cooled refrigerator 100 according to an embodiment of the present invention, and fig. 3 is a rear view of the inner container 111 of the air-cooled refrigerator 100 according to an embodiment of the present invention. As shown in fig. 1 to 3, the air-cooled refrigerator 100 of the present embodiment may generally include: the refrigerator body 110, the door body 120 and the refrigerated return air duct 130.
The box body 110 defines a storage compartment therein, and the storage compartment includes a refrigerating compartment 112 and a temperature-changing compartment 113. Specifically, the box body 110 may include an inner container 111 and an outer casing (not shown), and an insulating layer (not shown) is filled between the inner container 111 and the outer casing. And, the inner container 111 defines the storage compartment. As shown in fig. 1 and fig. 2, the refrigerator 100 of the present embodiment may include three storage compartments arranged from top to bottom, and the three storage compartments may be configured from top to bottom according to different purposes: a refrigerating compartment 112, a temperature-changing compartment 113 and a freezing compartment 114. Each storage compartment can be divided into a plurality of storage areas by a dividing plate, and the articles are stored by racks or drawers.
A cooling chamber 115 is further defined inside the cabinet 110, and an evaporator is provided inside the cooling chamber 115 to provide cooling energy to the storage compartment. As shown in fig. 2, the freezing chamber 114 and the cooling chamber 115 may be in a front-rear positional relationship, that is, the cooling chamber 115 is located behind the freezing chamber 114. That is, the refrigerating compartment 112, the variable temperature compartment 113, and the cooling compartment 115 are also disposed in a positional relationship from top to bottom. The evaporators provide different cooling capacities for various storage compartments, so that the temperatures in the various storage compartments are different. For example, the temperature in the refrigerated compartment 112 is generally between 2 ℃ and 10 ℃, preferably between 4 ℃ and 7 ℃. The temperature in the freezer compartment 114 is typically in the range of-22 c to-14 c. The temperature range within the temperature-changing compartment 113 is typically between 10 ℃ and 20 ℃.
The door 120 is disposed at a front side of the cabinet 110 to operatively open and close the storage compartment. The door bodies 120 may be disposed corresponding to the storage compartments, that is, one or more door bodies 120 may be disposed corresponding to each storage compartment. The door 120 may be pivotally disposed on a front surface of the cabinet 110, and may also be opened in a drawer manner. Fig. 4 is a partial schematic view of the inner container 111 of the air-cooled refrigerator 100 according to one embodiment of the present invention. The refrigerated return air duct 130 is provided with a first sub return air door 134 and a second sub return air door 135, when the first sub return air door 134 is opened, the refrigerated return air duct 130 is communicated with the refrigerated compartment 112 and the variable temperature compartment 113, so that at least part of air in the refrigerated compartment 112 enters the variable temperature compartment 113; when the second sub-return air damper 135 is open, the refrigerated return air duct 130 communicates between the refrigerated compartment 112 and the cooling compartment 115 to allow at least some of the air in the refrigerated compartment 112 to enter the cooling compartment 115. Because the humidity of the air in the refrigerating chamber 112 is high, the air in the refrigerating chamber 112 is introduced into the temperature-changing chamber 113, so that the humidity in the temperature-changing chamber 113 can be effectively improved, the air drying of food in the temperature-changing chamber 113 is avoided, and the storage effect is improved.
Specifically, as shown in fig. 3 and 4, the refrigerated return air duct 130 may include: a main return air duct 131, a first sub-return air duct 132, and a second sub-return air duct 133. In practice, fig. 4 is a schematic view of the inner container 111 with the main return air duct 131 removed to show the first sub-return air damper 134 and the second sub-return air damper 135. The return air main duct 131 is in communication with the refrigerating compartment 112. The first sub-return air duct 132 has one end in controlled communication with the return air main duct 131 through the first sub-return air damper 134, and has the other end in communication with the variable temperature compartment 113, so that at least part of the air in the refrigerating compartment 112 enters the variable temperature compartment 113. A second sub-return air duct 133 is in controlled communication with the return air main duct 131 through a second sub-return air damper 135 at one end and with the cooling compartment 115 at the other end, so that air in the refrigerated compartment 112 at least partially enters the cooling compartment 115. The refrigerating return air duct 130 enables the refrigerating compartment 112 to return air to the cooling chamber 115, so as to realize refrigeration cycle; and returns the air to the temperature-varying chamber 113 to increase the humidity of the temperature-varying chamber 113. The air duct structure of the air-cooled refrigerator 100 is reasonably arranged, other humidifying equipment is not required to be arranged, the production cost is effectively reduced, and meanwhile, the extra equipment can be prevented from occupying the storage space.
In addition, the air-cooled refrigerator 100 may further include: a heater (not shown) is disposed in the temperature-changing chamber 113 and is configured to be controllably activated to raise the temperature inside the temperature-changing chamber 113. The heat provided by the heater and the cold provided by the evaporator are matched, so that the temperature range of the variable temperature chamber 113 can reach 10 ℃ to 20 ℃. The optimal storage temperatures of different types of articles are different, and therefore the storage compartments suitable for storage are also different. For example, the fruit and vegetable food is preferably stored in the refrigerating compartment 112 or the temperature-changing compartment 113, and the meat food is preferably stored in the freezing compartment 114.
The air-cooled refrigerator 100 may further include: a refrigerated air supply duct 150 and a variable temperature air supply duct 160. The refrigerating air supply duct 150 is configured to controllably communicate the cooling chamber 115 with the refrigerating compartment 112 through a refrigerating air supply damper (not shown) to supply cooling energy to the refrigerating compartment 112. The variable temperature air supply duct 160 is configured to communicate the cooling chamber 115 with the variable temperature chamber 113 in a controlled manner through a variable temperature air supply damper (not shown) to supply cooling energy to the variable temperature chamber 113. In addition, the air-cooled refrigerator 100 may further include: variable temperature return air duct 140 communicates between variable temperature compartment 113 and cooling compartment 115, and returns the air in variable temperature compartment 113 to cooling compartment 115.
Since the temperature in the refrigerating compartment 112 is lower than that in the variable temperature compartment 113, when the refrigerating compartment 112 returns to the variable temperature compartment 113, not only the humidity in the variable temperature compartment 113 can be raised, but also the temperature in the variable temperature compartment 113 can be lowered. In a specific embodiment, under the condition that the air-cooled refrigerator 100 is normally cooled, the variable-temperature compartment 113 supplies air for cooling through the normal variable-temperature air supply duct 160, and air return of the refrigerating compartment 112 is not needed, at this time, the first sub-air return air door 134 is closed, and the second sub-air return air door 135 is opened; fruits and vegetables are stored in the variable-temperature chamber 113, when the humidity needs to be increased, the cold storage chamber 112 returns air to the variable-temperature chamber 113 through the first sub return air duct 132, so that the moisture preservation and refrigeration are realized, at the moment, the first sub return air door 134 is opened, and the second sub return air door 135 is closed.
The first sub-return air damper 134 and the second sub-return air damper 135 are opened at the same time as much as possible. The first sub return air door 134 is closed, and the second sub return air door 135 is opened, so that the air in the refrigerating compartment 112 can enter the cooling chamber 115 as much as possible, and the efficiency of the refrigeration cycle is improved; the first sub-return air damper 134 is opened and the second sub-return air damper 135 is closed, so that as much air in the refrigerating compartment 112 as possible can be ensured to enter the variable temperature compartment 113, and the humidity and the temperature of the variable temperature compartment 113 can be effectively adjusted.
As can be seen from fig. 3 and 4, in a preferred embodiment, from the perspective of the back of the inner container 111, the inlet of the return air main duct 131 may be disposed at the lower right side of the refrigerating compartment 112, the outlet of the return air main duct 131 is connected to the inlet of the first sub-return air duct 132 and the inlet of the second sub-return air duct 133, respectively, the outlet of the first sub-return air duct 132 is disposed at the upper right side of the variable temperature compartment 113, and the outlet of the second sub-return air duct 133 is disposed at the lower middle part of the cooling compartment 115. The inlet of the variable-temperature return air duct 140 is disposed on the left lower side of the variable-temperature compartment 113, and the outlet of the variable-temperature return air duct 140 is disposed on the left side of the lower middle portion of the cooling compartment 115. The inlet of the refrigerated air supply duct 150 is arranged on the right side of the upper middle part of the cooling chamber 115, and the outlet of the refrigerated air supply duct 150 is arranged on the lower middle part of the refrigerating chamber 112. The inlet of the variable temperature air supply duct 160 is disposed on the left side of the upper middle portion of the cooling compartment 115, and the outlet of the variable temperature air supply duct 160 is disposed on the left side of the upper middle portion of the refrigerating compartment 112. The specific inlet and outlet positions of each air channel are reasonably arranged, so that the air supply and return are ensured to be timely and quick, and meanwhile, the interference among the air channels is avoided.
Fig. 5 is a schematic block diagram of an air-cooled refrigerator 100 according to one embodiment of the present invention. The air-cooled refrigerator 100 comprises a control device 200, the control device 200 comprises a processor 210 and a memory 220, wherein the memory 220 stores a control program 221, and the control program 221 is used for realizing the control method of the air-cooled refrigerator of any one of the following embodiments when being executed by the processor 210.
Fig. 6 is a schematic diagram of a control method of an air-cooled refrigerator according to an embodiment of the present invention. As shown in fig. 6, the control method of the air-cooled refrigerator may perform the following steps:
step S602, acquiring refrigeration conditions of the refrigerating compartment 112 and the variable temperature compartment 113;
step S604, judging whether the refrigerating chamber 112 and the temperature-changing chamber 113 both need to be refrigerated, if so, executing step S606;
step S606, the first sub return air door 134 is controlled to be opened, the second sub return air door 135 is controlled to be closed, and when the actual temperature of the variable temperature compartment 113 is less than or equal to the variable temperature shutdown temperature, the first sub return air door 134 is controlled to be closed, and the second sub return air door 135 is controlled to be opened.
In step S602, the refrigeration conditions of the refrigerating compartment 112 and the temperature-changing compartment 113 are obtained, wherein the refrigeration conditions include refrigeration requirement and refrigeration non-requirement. In step S606, the first sub return air damper 134 is controlled to be opened, the second sub return air damper 135 is controlled to be closed, and actually, the refrigerating compartment 112 returns air to the variable temperature compartment 113, and since the humidity of the air in the refrigerating compartment 112 is high, the air in the refrigerating compartment 112 is introduced into the variable temperature compartment 113, so that the humidity in the variable temperature compartment 113 can be effectively increased, and the air drying of the food therein is avoided, thereby improving the storage effect.
In addition, because the temperature in the refrigerating compartment 112 is lower than that in the temperature-changing compartment 113, when the refrigerating compartment 112 returns air to the temperature-changing compartment 113, not only can the humidity in the temperature-changing compartment 113 be raised, but also the temperature of the temperature-changing compartment 113 can be lowered, and the requirement that the temperature-changing compartment 113 needs to be refrigerated is met. When the actual temperature of the variable temperature compartment 113 is equal to or lower than the variable temperature shutdown temperature, the first sub return air damper 134 is controlled to be closed, and the second sub return air damper 135 is controlled to be opened. When the actual temperature of the variable temperature compartment 113 is less than or equal to the variable temperature shutdown temperature, the refrigeration condition of the variable temperature compartment 113 is changed to no need of refrigeration, so that the first sub return air door 134 is controlled to be closed, the second sub return air door 135 is controlled to be opened, and the cold storage compartment 112 does not return air to the variable temperature compartment 113 any more to reduce the temperature of the variable temperature compartment 113.
In some optional embodiments, the air-cooled refrigerator 100 may achieve a higher technical effect by further optimizing and configuring the above steps, and the following describes in detail the control method of the air-cooled refrigerator of this embodiment in combination with a description of an optional execution flow of this embodiment, where this embodiment is merely an illustration of the execution flow, and in a specific implementation, an execution sequence and an operation condition of a part of steps may be modified according to specific implementation requirements.
