Detailed ways

This embodiment first provides an air-cooled refrigerator, which can introduce gas with high humidity in the refrigerating compartment into the temperature-changing compartment, increase the humidity in the temperature-changing compartment, and prevent the food in it from drying out, thereby improving the storage effect. 1 is a schematic structural diagram of an air-cooled refrigerator 100 according to an embodiment of the present invention, FIG. 2 is a front view of an inner pot 111 of the air-cooled refrigerator 100 according to an embodiment of the present invention, and FIG. 3 is an embodiment of the present invention. A rear view of the inner pot 111 of the air-cooled refrigerator 100 . As shown in FIGS. 1 to 3 , the air-cooled refrigerator 100 of this embodiment may generally include: a box body 110 , a door body 120 and a refrigerated return air duct 130 .

A storage compartment is defined inside the box body 110 , and the storage compartment includes a refrigerating compartment 112 and a temperature-changing compartment 113 . Specifically, the box 110 may include an inner container 111 and an outer shell (not shown in the figure), and a thermal insulation layer (not shown in the figure) is filled between the inner container 111 and the outer shell. And, the inner container 111 defines the above-mentioned storage compartment. As shown in FIG. 1 and FIG. 2 , the refrigerator 100 of this embodiment may include three storage compartments arranged from top to bottom, and from top to bottom may be respectively configured as: refrigerating compartment 112 , temperature changing compartment from top to bottom according to different purposes Compartment 113 and freezer compartment 114. Each storage compartment can be divided into a plurality of storage areas by a dividing board, and the items can be stored by using a shelf or a drawer.

A cooling chamber 115 is also defined inside the box body 110, and an evaporator is arranged in the cooling chamber 115 to provide cooling capacity to the storage compartment. As shown in FIG. 2 , the freezing compartment 114 and the cooling compartment 115 may be in a front and rear positional relationship, that is, the cooling compartment 115 is located behind the freezing compartment 114 . That is, in fact, the refrigerating compartment 112, the temperature-changing compartment 113, and the cooling compartment 115 are also arranged in a positional relationship from top to bottom. The cooling capacity provided by the evaporator to various types of storage compartments is different, so that the temperatures in the various types of storage compartments are also different. For example, the temperature in the refrigerated compartment 112 is generally between 2°C and 10°C, preferably 4°C to 7°C. The temperature range within the freezer compartment 114 is typically -22°C to -14°C. The temperature range in the variable temperature compartment 113 is generally 10°C to 20°C.

The door body 120 is disposed on the front side of the box body 110 to operably open and close the storage compartment. The door bodies 120 may be provided corresponding to the storage compartments, that is, each storage compartment is correspondingly provided with one or more door bodies 120 . The door body 120 can be pivotally disposed on the front surface of the box body 110, and can also be opened in a drawer type. FIG. 4 is a partial schematic view of the inner container 111 of the air-cooled refrigerator 100 according to an 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 connected to the refrigerating compartment 112 and the temperature-changing compartment 113, so that the gas in the refrigerating compartment 112 at least partially enters the temperature-changing compartment 113; when the second sub-return air door 135 is opened, the refrigerating return air duct 130 connects the refrigerating compartment 112 and the cooling compartment 115, so that the refrigerating compartment The gas within 112 at least partially enters cooling chamber 115 . Since the gas humidity in the refrigerating compartment 112 is relatively high, introducing the gas in the refrigerating compartment 112 into the temperature-changing compartment 113 can effectively increase the humidity in the temperature-changing compartment 113 to prevent the food in it from drying out, thereby improving the storage effect.

Specifically, as shown in FIGS. 3 and 4 , the refrigerated return air duct 130 may include: a general return air duct 131 , a first sub-return air duct 132 and a second sub-return air duct 133 . In fact, FIG. 4 is a schematic diagram of the inner tank 111 except the main return air duct 131 to show the first sub-return air damper 134 and the second sub-return air damper 135 . Wherein, the general return air duct 131 communicates with the refrigerating compartment 112 . One end of the first sub-return air duct 132 is in controlled communication with the main return air duct 131 through the first sub-return air door 134, and the other end is in communication with the temperature-changing compartment 113, so that the gas in the refrigerating compartment 112 is at least partially connected. Enter the variable temperature room 113 . One end of the second sub-return air duct 133 is in controlled communication with the main return air duct 131 through the second sub-return air damper 135, and the other end is in communication with the cooling chamber 115, so that the gas in the refrigerating compartment 112 at least partially enters Cooling chamber 115 . The refrigerated return air duct 130 enables the refrigerating compartment 112 to return air to the cooling compartment 115 to realize a refrigeration cycle; Reasonable arrangement of the air duct structure of the air-cooled refrigerator 100 eliminates the need to arrange other humidification equipment, thereby effectively reducing the production cost, and at the same time, additional equipment can be prevented from occupying storage space.

In addition, it should be noted that the air-cooled refrigerator 100 may further include: a heater (not shown in the figure) disposed in the temperature-changing compartment 113 and configured to be controlled to open to increase the temperature inside the temperature-changing compartment 113 . The heat provided by the heater and the cooling capacity provided by the evaporator should be matched, so that the temperature range of the variable temperature compartment 113 can reach 10°C to 20°C. The optimal storage temperature for different types of items is not the same, and the storage compartments suitable for storage are also different. For example, fruits and vegetables are preferably stored in the refrigerating compartment 112 or the temperature-changing compartment 113 , and meat foods are preferably stored in the freezing compartment 114 .

It should be noted that, since the temperature in the refrigerating compartment 112 is lower than that in the variable temperature compartment 113 , when the refrigerating compartment 112 returns air to the variable temperature compartment 113 , the humidity in the variable temperature compartment 113 can not only be increased, but also the temperature can be reduced. temperature of compartment 113. In a specific embodiment, when the air-cooled refrigerator 100 is normally refrigerated, the temperature-changing compartment 113 is supplied with air for cooling through the normal temperature-changing air supply air duct 160, and no return air from the refrigerating compartment 112 is required. The 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 compartment 113, and when the humidity needs to be increased, the first sub-air return air duct 132 can be used to realize the return air from the refrigerating compartment 112 to the variable temperature room At this time, the first sub-return air damper 134 is opened, and the second sub-return air damper 135 is closed.

The first sub-return air damper 134 and the second sub-return air damper 135 are not opened at the same time as possible. The first sub-return air damper 134 is closed, and the second sub-return air damper 135 is opened, which can ensure that as much gas of the refrigerating compartment 112 enters the cooling chamber 115 as possible, and improves the efficiency of the refrigeration cycle; the first sub-return air damper 134 is opened, The closing of the second sub-return air damper 135 can ensure that as much gas of the refrigerating compartment 112 enters into the temperature-changing compartment 113 as possible, so as to effectively adjust the humidity and temperature of the temperature-changing compartment 113 .

It can be seen from FIG. 3 and FIG. 4 that, in a preferred embodiment, from the perspective of the back of the inner bladder 111, the entrance of the general return air duct 131 can be arranged on the lower right side of the refrigerating compartment 112, and the total return air The outlet of the duct 131 is respectively connected with the inlet of the first sub-return air duct 132 and the inlet of the second sub-return air duct 133. The outlet of the second sub-return air duct 133 is disposed on the right of the lower middle of the cooling chamber 115 . The inlet of the temperature-variable return air duct 140 is arranged on the lower left side of the temperature-changing compartment 113 , and the outlet of the temperature-variable return air duct 140 is arranged to the left of the lower middle of the cooling chamber 115 . The inlet of the refrigerated air supply duct 150 is arranged in the upper middle of the cooling compartment 115 to the right, and the outlet of the refrigerated air supply duct 150 is arranged in the lower middle of the refrigerating compartment 112 . The inlet of the variable temperature air supply duct 160 is set to the left in the upper middle of the cooling chamber 115 , and the outlet of the variable temperature air supply duct 160 is set to the left of the upper middle of the refrigerating compartment 112 . The positions of the specific inlets and outlets of the above air ducts are set reasonably to ensure timely and rapid air supply and return air, and to avoid interference between the air ducts.

FIG. 5 is a schematic block diagram of an air-cooled refrigerator 100 according to an embodiment of the present invention. The air-cooled refrigerator 100 includes a control device 200, and the control device 200 includes a processor 210 and a memory 220, wherein the memory 220 stores a control program 221, and when the control program 221 is executed by the processor 210, is used to implement any of the following embodiments. Control method of air-cooled refrigerator.

This embodiment also provides a control method for an air-cooled refrigerator, and FIG. 6 is a schematic diagram of a control method for an air-cooled refrigerator according to an embodiment of the present invention. As shown in Figure 6, the control method of the air-cooled refrigerator may perform the following steps:

Step S602, obtaining the cooling status of the refrigerating compartment 112 and the temperature-changing compartment 113;

Step S604, it is judged whether the refrigeration compartment 112 and the temperature-changing compartment 113 both need to be cooled, and if so, go to Step S606;

Step S606, control the first sub-return air door 134 to open and the second sub-return air door 135 to close, and when the actual temperature of the variable temperature compartment 113 is less than or equal to the variable temperature shutdown temperature, control the first sub-return air door 134 to close, and the second sub-return air door 134 to close. The sub-return air damper 135 is opened.

In step S602, the cooling conditions of the refrigerating compartment 112 and the temperature-changing compartment 113 are acquired, wherein the cooling conditions include the need for cooling and the need for cooling. In step S606, the first sub-return air damper 134 is controlled to be opened, and the second sub-return air damper 135 is closed. In fact, the refrigerating compartment 112 is returned to the temperature-changing compartment 113. Since the gas humidity in the refrigerating compartment 112 is relatively high, the air in the refrigeration compartment 112 is relatively high. The gas in the refrigerating compartment 112 is introduced into the temperature-changing compartment 113, which can effectively increase the humidity in the temperature-changing compartment 113, and prevent the food in it from drying out, thereby improving the storage effect.

In addition, since the temperature in the refrigerating compartment 112 is lower than that in the temperature changing compartment 113 , when the refrigerating compartment 112 is returned to the temperature changing compartment 113 , the humidity in the changing temperature compartment 113 can not only be increased, but also the temperature in the changing temperature compartment 113 can be lowered. The temperature of the variable temperature compartment 113 needs to be refrigerated. In addition, 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 damper 134 is controlled to close, and the second sub-return air damper 135 is opened. When the actual temperature of the variable temperature compartment 113 is less than or equal to the variable temperature shutdown temperature, the cooling state of the variable temperature compartment 113 changes to no cooling, so the first sub-return air damper 134 is controlled to close, the second sub-return air damper 135 is opened, and the refrigerating compartment 112 The temperature of the variable temperature compartment 113 is lowered by not returning air to the variable temperature compartment 113 .

In some optional embodiments, the air-cooled refrigerator 100 can achieve a higher technical effect by further optimizing and configuring the above steps. The control method is described in detail in this embodiment. This embodiment is only an example of the execution process. During specific implementation, the execution sequence and operating conditions of some steps may be modified according to specific implementation requirements. 7 is a detailed flowchart of a control method for an air-cooled refrigerator according to an embodiment of the present invention, and the control method for the air-cooled refrigerator includes the following steps:

Step S704, it is judged whether the refrigeration compartment 112 and the temperature-changing compartment 113 both need to be cooled, and if so, go to Step S606;

Step S706, control the refrigerating air supply air door to open, and the variable temperature air supply air door to close;

Step S708, control the first sub-return air damper 134 to open and the second sub-return air damper 135 to close, and control the first sub-return air damper 134 to close and the second sub-return air damper 134 to close when the actual temperature of the variable temperature compartment 113 is less than or equal to the variable temperature shutdown temperature. The sub-return air damper 135 is opened.

In step S706, the refrigerating air supply air door is controlled to open, and the variable temperature air supply air door is closed. In step S708, the first sub-return air door 134 is controlled to open, and the second sub-air return air door 135 is closed. 112 needs to be cooled. Although the variable temperature air supply door is closed, it cannot be cooled by the supply air of the cooling chamber 115, but the first sub-air return air door 134 is opened, so that the refrigerated room 112 with high humidity and low temperature returns the air to the variable temperature The compartment 113 can not only increase the humidity in the temperature-changing compartment 113 , but also lower the temperature of the temperature-changing compartment 113 , so as to meet the cooling demand of the temperature-changing compartment 113 .

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 damper 134 is controlled to close, and the second sub-return air damper 135 is opened. At this time, the refrigerating compartment 112 returns air to the cooling compartment 115, and the refrigerating air supply air door is opened, and the cooling compartment 115 sends air to the refrigerating compartment 112, thus forming a refrigeration cycle to ensure that the cooling demand of the refrigerating compartment 112 is fully satisfied. The control method of the air-cooled refrigerator in this embodiment takes into account the temperature and humidity of the storage compartment, and meets the storage requirements of users.

8 is a detailed flowchart of a control method for an air-cooled refrigerator according to yet another embodiment of the present invention, and the control method for the air-cooled refrigerator includes the following steps:

Step S802, obtaining the cooling status of the refrigerating compartment 112 and the temperature-changing compartment 113;

Step S804, in the case that the refrigerating compartment 112 needs to be cooled and the temperature-changing compartment 113 does not need to be cooled, obtain the ambient temperature of the environment where the air-cooled refrigerator 100 is located;

Step S806, determine whether the ambient temperature is greater than or equal to the preset temperature value, if yes, go to step S808, if not, go to step S810;

Step S808, controlling the refrigerating air supply air door to open, the variable temperature air supply air door to close, the first sub-return air door 134 to be opened after being closed for a first preset time period, and the second sub-air return air door 135 to be opened for a first preset time period and then closed;
