Referring to fig. 7, in some embodiments, a refrigerating circuit is formed by sequentially connecting a compressor 2, a condenser 3, a capillary tube 6, a freezing evaporator 4 and a refrigerating evaporator 5, and a refrigerant circulates in the refrigerating circuit to realize refrigeration of the interior of the box 1.

Wherein, compressor 2 is installed in box 1. The compressor 2 is configured to compress refrigerant vapor to form high-temperature, high-pressure refrigerant vapor. The compressor 2 has a discharge port 21 and a return port 22, and compressed refrigerant vapor flows out of the compressor 2 from the discharge port 21, and the cooled refrigerant returns to the compressor 2 through the return port 22.

In some embodiments, a press house (not shown) is provided in the case 1, and the compressor 2 is installed in the press house. A cooling fan (not shown in the figure) is arranged in the press bin and is used for providing wind power, and wind formed by the cooling fan can cool the compressor 2.

In some embodiments, the condenser 3 is disposed in the compressor 2 cabin, and the air formed by the cooling fan can also cool the condenser 3. It should be noted that, in other embodiments, the condenser 3 may be disposed at other positions of the case 1, for example, the condenser 3 is disposed on a side wall or a back surface of the case 1.

Referring to fig. 7, in some embodiments, the outlet end of the condenser 3 is connected to the inlet end of the capillary tube 6, and the outlet end of the capillary tube 6 is connected to the inlet end of the freeze evaporator 4.

Specifically, the refrigerant enters the freezing evaporator 4 from the capillary tube 6 to absorb heat by evaporation, so that the freezing evaporator 4 can absorb heat in the air in the freezing evaporation bin 14, and the temperature of the air in the freezing evaporation bin 14 is reduced to form cool air.

Referring to fig. 7, in some embodiments, the outlet end of the freezing evaporator 4 is connected to the inlet end of the refrigerating evaporator 5, and the outlet end of the refrigerating evaporator 5 is connected to the return air port 22 of the compressor 2, so that a refrigerating circuit is formed among the compressor 2, the condenser 3, the capillary tube 6, the freezing evaporator 4 and the refrigerating evaporator 5.

In some embodiments, an air return pipe 23 is provided at the air return port 22 of the compressor 2, and the outlet end of the refrigeration evaporator 5 is connected to the air return port 22 of the compressor 2 through the air return pipe 23.

Referring to fig. 4 to 7, in some embodiments, a refrigeration evaporation bin 15 is disposed in the case 1, the refrigeration evaporator 5 is disposed in the refrigeration evaporation bin 15, and the refrigeration evaporator 5 is configured to cool the refrigeration evaporation bin 15, so that a large amount of cool air is formed in the refrigeration evaporation bin 15. Specifically, the refrigerant enters the refrigeration evaporator 5 to absorb heat by evaporation, so that the refrigeration evaporator 5 can absorb heat in the air in the refrigeration evaporation bin 14, and the temperature of the air in the refrigeration evaporation bin 15 is reduced to form cool air.

Referring to fig. 3 to 6, in some embodiments, the freezing chamber 110 has a freezing air outlet 111 and a freezing air return 112. The freezing air outlet 111 is communicated with the air outlet end of the freezing evaporation bin 14, and the freezing air return 112 is communicated with the air inlet end of the refrigerating evaporation bin 15. Meanwhile, the freezing and evaporating bin 14 is communicated with the refrigerating and evaporating bin 15, and the refrigerating and evaporating bin 15 is positioned at the air inlet end of the freezing and evaporating bin 14, namely the air inlet end of the freezing and evaporating bin 14 is communicated with an air outlet end of the refrigerating and evaporating bin 15. Therefore, the air in the freezing chamber 110 can enter the refrigeration evaporation bin 15 through the freezing air return port 112, and the air is cooled by the refrigeration evaporator 5 after flowing through the refrigeration evaporator 5; and then enters the freezing evaporation bin 14 from the air outlet end of the refrigeration evaporator 5, flows through the refrigeration evaporator 4, is further cooled by the refrigeration evaporator 4, and finally formed cold air enters the freezing chamber 110 through the refrigeration air outlet 111 to form refrigeration air circulation, and realizes refrigeration of the freezing chamber 110.

In the refrigerating air cycle, the humidity in the air in the freezing chamber 110 is preferentially condensed on the refrigerating evaporator 5, and after the air flows out of the refrigerating evaporation bin 15, only a small part of the humidity in the air enters the refrigerating evaporation bin 14 to condense on the refrigerating evaporator 4. Accordingly, the amount of frost on the freezing evaporator 4 can be greatly reduced, so that the defrosting time of the freezing evaporator 4 can be greatly reduced, and the power consumption of the refrigerator and the temperature fluctuation of the freezing chamber 110 can be reduced.

Referring to fig. 4 to 6, in some embodiments, a baffle 16 is disposed at a connection between the refrigeration evaporation bin 15 and the freezing evaporation bin 14, the baffle 16 is rotatably disposed at a connection between the refrigeration evaporation bin 15 and the freezing evaporation bin 14, and the baffle 16 is used for opening and closing an air inlet end of the freezing evaporation bin 14. Therefore, when the interior of the freezing chamber 110 needs to be refrigerated, the air inlet end of the freezing and evaporating chamber 14 is opened by the baffle 16, so that the air in the refrigerating and evaporating chamber 5 can enter the freezing and evaporating chamber 14, and then is led into the freezing chamber 110 through the freezing air outlet 111 for refrigeration. When the freezing chamber 110 does not need to be refrigerated or the freezing evaporator 4 needs to be defrosted, the baffle 16 can be closed to isolate the freezing evaporator 4 from the freezing evaporation bin 14 for naturally defrosting or the heater is used for heating and defrosting. In addition, the freezing evaporator 4 does not affect the normal use of the refrigeration evaporator compartment 15 and the refrigeration evaporator 5 during defrosting.

It should be noted that in some embodiments, the baffle 16 may be a fan blade window type baffle 16. In other embodiments, the baffle 16 may be replaced with a damper arrangement.

Referring to fig. 3 to 5, in some embodiments, a side of the freezing and evaporating bin 14 away from the refrigerating and evaporating bin 15 is connected to a freezing air supply duct 141, and the freezing air supply duct 141 is connected to the freezing air outlet 111. Therefore, the freezing and evaporating bin 14 can be communicated with the freezing chamber 110 through the freezing air supply duct 141 and the freezing air outlet 111 in sequence, so that the cold air in the freezing and evaporating bin 14 can flow into the freezing chamber 110 through the freezing air supply duct 141 and the freezing air outlet 111 in sequence, and the refrigerating function of the freezing chamber 110 is realized.

In some embodiments, the freezing air outlets 111 are provided in plurality, and the plurality of freezing air outlets 111 are arranged on the side wall of the freezing chamber 110 at intervals to improve the air inlet speed and the cooling efficiency in the freezing chamber 110. The number of the refrigerating outlets 111 may be adjusted as needed, and is not limited herein.

In some embodiments, a freezing blower 142 is disposed at a communication position between the freezing air supply channel 141 and the freezing and evaporating bin 14, and the freezing blower 142 is used for providing wind power, so that the cold air in the freezing and evaporating bin 14 can flow into the freezing air supply channel 141, and then flow into the freezing chamber 110 through the freezing air outlet 111 for refrigeration.

Referring to fig. 3 to 5, in some embodiments, a refrigerating chamber 120 has a refrigerating outlet 121 and a refrigerating return 122. Meanwhile, the freezing air supply duct 141 is communicated with one end of the refrigerating air supply duct 123, the other end of the refrigerating air supply duct 123 is communicated with the refrigerating air outlet 121, and the refrigerating air return opening 122 is communicated with the air inlet end of the refrigerating evaporation bin 15. Therefore, the cool air in the freezing and evaporating compartment 14 can flow into the freezing and air-supplying duct 141, and enter the refrigerating chamber 120 through the refrigerating and air-supplying duct 123 and the refrigerating air-outlet 121, thereby refrigerating the refrigerating chamber 120. The air in the refrigerating chamber 120 can return to the refrigerating evaporation bin 15 through the refrigerating return air opening 122, and is cooled again by the refrigerating evaporator 5, and the cooled air can enter the freezing evaporation bin 14 and is further cooled by the freezing evaporator 4, so that a refrigerating first air circulation is formed.

In some embodiments, the plurality of refrigerating outlets 121 are provided, and the plurality of refrigerating outlets 121 are arranged on the side wall of the refrigerating compartment 120 at intervals to improve the air inlet speed and the cooling efficiency in the refrigerating compartment 120. The number of the refrigerating outlets 121 may be adjusted as needed, and is not limited herein.

In some embodiments, a refrigeration damper 124 is disposed in the refrigeration air supply duct 123, and the refrigeration damper 124 is configured to open and close the refrigeration air supply duct 123. When the temperature in the refrigerating chamber 120 reaches the preset threshold or the refrigerating chamber 120 does not need to be refrigerated, the refrigerating air door 124 is closed to prevent the cool air in the freezing and evaporating bin 14 from entering the refrigerating chamber 120, and thus the refrigerating chamber 120 is stopped, and at this time, the freezing chamber 110 can be independently refrigerated, as shown in fig. 5.

When the refrigeration damper 124 is opened, the refrigerating air cycle and the first refrigerating air cycle may be performed simultaneously, thereby achieving simultaneous refrigeration of the refrigerating compartment 120 and the freezing compartment 110.

Referring to fig. 4 to 6, in some embodiments, a refrigerating fan 17 is further disposed in the case 1, the refrigerating fan 17 is disposed on a side wall of the air outlet end of the refrigerating evaporation bin 15, and the refrigerating fan 17 communicates between the refrigerating evaporation bin 15 and the refrigerating chamber 120. The refrigerating fan 17 can drive the air in the refrigerating evaporation bin 15 to directly enter the refrigerating chamber 120, and enable the air in the refrigerating chamber 120 to return to the refrigerating evaporation bin 15 through the refrigerating air return opening 122, so as to form a refrigerating second air circulation.

When the frost on the refrigeration evaporator 5 is increased, and the refrigeration evaporator 5 needs to be defrosted, the communicating part of the refrigeration evaporation bin 15 and the refrigeration evaporation bin 14 can be closed through the baffle 16, namely, the air inlet end of the refrigeration evaporation bin 14 is closed through the baffle 16, the refrigeration fan 17 is started at the same time, and then the refrigeration second air circulation is started, so that the refrigeration chamber 120 can be independently refrigerated, the refrigeration evaporator 5 is defrosted through the heat in the air in the refrigeration chamber 120, and meanwhile, the moisture on the refrigeration evaporator 5 can enter the refrigeration chamber 120 to humidify the refrigeration chamber 120, and further the refrigeration and moisture preservation functions are achieved in the refrigeration chamber 120. The defrosting mode can greatly reduce the power consumption of the refrigerator.

Referring to fig. 3 to 6, in some embodiments, the freeze evaporation bin 14 and the refrigeration evaporation bin 15 are both disposed in the partition region 100 within the partition portion, that is, the freeze evaporation bin 14 and the refrigeration evaporation bin 15 are both disposed in the partition region 100 between the freezing chamber 110 and the refrigeration chamber 120, and the freeze evaporation bin 14 and the refrigeration evaporation bin 15 are both disposed in the partition region 100 between the first container 11 and the second container 12. The freezing evaporation bin 14 and the refrigeration evaporation bin 15 are arranged in an up-down separation mode, a baffle 16 is arranged at a separation area between the freezing evaporation bin 14 and the refrigeration evaporation bin 15, and the baffle 16 controls the communication or closing between the freezing evaporation bin 14 and the refrigeration evaporation bin 15.

It should be noted that, in other embodiments, the freeze evaporation bin 14 and the refrigeration evaporation bin 15 may be disposed in the area on the back sides of the freezing chamber 110 and the refrigeration chamber 120, that is, the freeze evaporation bin 14 and the refrigeration evaporation bin 15 may be disposed in the area on the back sides of the first liner 11 and the second liner 12.

Referring to fig. 3 to 6, in some embodiments, the freezing air outlet 111 and the freezing air return 112 are disposed on the side wall of the freezing chamber 110 facing the partition area 100, so that the distance between the freezing air outlet 111 and the freezing and evaporating chambers 14 and the distance between the freezing air return 112 and the refrigerating and evaporating chambers 15 can be shortened, so that the cold air in the freezing and evaporating chambers 14 can enter the freezing chamber 110 from the freezing air outlet 111 nearby, and the air in the freezing chamber 110 can also enter the refrigerating and evaporating chambers 15 from the freezing air return 112 nearby.

In other embodiments, the freezing air outlet 111 and the freezing air return 112 are disposed on other sidewalls of the freezing chamber 110.

Referring to fig. 3 to 6, in some embodiments, the refrigerating fan 17 and the refrigerating return opening 122 are disposed on a side wall of the refrigerating compartment 120 facing the partition area 100, so as to shorten the distance between the refrigerating fan 17 and the refrigerating evaporation bin 15 and the refrigerating compartment 120, and shorten the distance between the refrigerating return opening 122 and the refrigerating evaporation bin 15. Thus, when the baffle 16 is closed and the refrigeration second air cycle is independently turned on, cool air in the refrigerated evaporation compartment 15 can be allowed to enter the refrigeration compartment 120 from the refrigeration fan 17 in a close proximity and air in the refrigeration compartment 120 can be returned from the refrigeration return air opening 122 back into the refrigerated evaporation compartment 15 in a close proximity.

It should be noted that, in other embodiments, the refrigerating fan 17 and the refrigerating return air opening 122 may be disposed on other sidewalls of the refrigerating compartment 120.

It should be noted that, in other embodiments, the refrigeration outlet 121 may be disposed on a side wall of the refrigeration compartment 120 facing the partition 100, and the refrigeration air supply duct 123 may be disposed in the partition 100.

Referring to fig. 3 to 6, in some embodiments, a freezing heater (not shown) is provided on the freezing evaporator 4, and when the amount of frost on the freezing evaporator 4 increases, the freezing evaporator 4 may be defrosted by the freezing heater.

It should be noted that most of the time the refrigeration heater need not be used.

Fig. 8 is a schematic view of another embodiment of the interior of fig. 2. Fig. 9 is a cross-sectional view of fig. 8. Fig. 10 is a wind cycle diagram of fig. 9. Fig. 11 is another wind cycle diagram of fig. 9.

Referring to fig. 8 to 11, the refrigerator of the present embodiment has the same main structure as the refrigerator of the embodiment of fig. 3 to 6, and includes a refrigerator body 1, and a freezing chamber 110, a refrigerating chamber 120, a freezing and evaporating bin 14 and a refrigerating and evaporating bin 15 disposed in the refrigerator body 1. The main difference of this embodiment is that: the arrangement of the cool air supply duct 123 is different. One end of the refrigeration air supply duct 123 is communicated with the refrigeration air outlet 121, and one end of the refrigeration air supply duct 123 far away from the refrigeration air outlet 121 is not communicated with the refrigeration air supply duct 141, but is communicated with the refrigeration fan 17, namely, the refrigeration fan 17 is communicated with one end of the refrigeration air supply duct 123 and the refrigeration evaporation bin 15. Therefore, the cool air in the refrigerating evaporation chamber 15 can be directly sent into the refrigerating chamber 120 through the refrigerating fan 17, the refrigerating air supply duct 123 and the refrigerating air outlet 121, and the interior of the refrigerating chamber 120 is refrigerated. The air in the freezing and evaporating compartment 14 is only sent into the freezing compartment 110 through the freezing air supply duct 141 and the freezing air supply opening, and only the freezing compartment 110 is refrigerated, i.e., the air in the freezing and evaporating compartment 14 is not used for refrigerating the refrigerating compartment 120.

In this embodiment, only one refrigerating air circulation is provided in the refrigerating chamber 120, that is, air in the refrigerating chamber 120 enters the refrigerating evaporation bin 15 through the refrigerating air return port 122, and cold air in the refrigerating evaporation bin 15 returns to the refrigerating chamber 120 through the refrigerating fan 17, the refrigerating air supply duct 123 and the refrigerating air outlet 121 to form the refrigerating air circulation.

When the frost on the refrigerating evaporator 5 is increased, and the refrigerating evaporator 5 needs to be defrosted, the communicating part of the refrigerating evaporation bin 15 and the freezing evaporation bin 14 can be closed through the baffle 16, the refrigerating fan 17 is started at the same time, and then the refrigerating wind circulation is started, so that the refrigerating chamber 120 can be independently refrigerated, the refrigerating evaporator 5 can be defrosted through the heat in the air in the refrigerating chamber 120, and the moisture on the refrigerating evaporator 5 can enter the refrigerating chamber 120 to humidify the refrigerating chamber 120 while defrosting, and further the refrigerating and moisturizing functions are achieved in the refrigerating chamber 120. The defrosting mode can also greatly reduce the power consumption of the refrigerator.

Referring to fig. 8 to 11, in some embodiments, the refrigerating outlet 121 is disposed on a side wall of the refrigerating compartment 120 facing the partition 100, and the refrigerating air supply duct 123 is also disposed in the partition 100.

It should be noted that, in other embodiments, the refrigeration outlet 121 may be disposed on other side walls of the refrigeration compartment 120, and one end of the refrigeration air supply duct 123 may also be disposed on other side walls of the refrigeration compartment 120 in an extending manner.

Fig. 12 is a diagram of the refrigeration system of fig. 9.

Referring to fig. 12, in some embodiments, the refrigeration system employs a series-parallel refrigeration system of a refrigeration evaporator 4 and a refrigeration evaporator 5. Wherein the discharge port 21 of the compressor 2 is connected to the inlet end of the condenser 3. The outlet end of the condenser 3 is connected with a switch valve 7. The switch valve 7 may employ a solenoid valve, the switch valve 7 having a first outlet 71 and a second outlet 72, the switch valve 7 may switch the first outlet 71 to open, the second outlet 72 to close, or switch to the first outlet 71 to close, the second outlet 72 to open.

The second outlet 72 of the switch valve 7 is connected to the inlet end of the refrigeration capillary 6b, and the outlet end of the refrigeration capillary 6b is connected to the inlet end of the refrigeration evaporator 5, i.e. the inlet end of the refrigeration evaporator 5 is connected to the outlet end of the refrigeration capillary 6b and the outlet end of the freezing evaporator 4, respectively. The outlet end of the refrigeration evaporator 5 is connected with an air return pipe 23, and is connected with an air return port 22 of the compressor 2 through the air return pipe 23, so as to form a refrigeration cycle loop with a series-parallel structure.

Referring to fig. 10, in some embodiments, when it is desired to simultaneously cool the freezing compartment 110 and the refrigerating compartment 120, the refrigerating fan 17 may be turned on, and the on-off valve 7 may be switched to open the first outlet 71 and close the second outlet 72. At this time, the refrigerating evaporation bin 15 and the refrigerating evaporator 5 simultaneously refrigerate the freezing chamber 110 and the refrigerating chamber 120, and the freezing evaporation bin 14 and the freezing evaporator 4 are separately used for refrigerating the freezing chamber 110, and the humidity of the air in the freezing chamber 110 and the refrigerating chamber 120 is mainly condensed on the refrigerating evaporator 5.

In some embodiments, when the freezing compartment 110 alone is required to be cooled, the refrigerating fan 17 may be turned off, while the switching valve 7 is switched to the first outlet 71 to be opened and the second outlet 72 to be closed. At this time, the refrigerating evaporation bin 15, the refrigerating evaporator 5, the freezing evaporation bin 14, and the freezing evaporator 4 are all used to cool the freezing chamber 110. The humidity of the air in the freezing chamber 110 is mainly condensed on the refrigerating evaporator 5.

Referring to fig. 11, in some embodiments, when the refrigerating compartment 120 is required to be cooled separately, the baffle 16 may be closed, the refrigerating fan 17 may be turned on, and the on-off valve 7 may be switched to the first outlet 71 to be closed and the second outlet 72 to be opened. At this time, the freezing evaporator 4 is not operated, the refrigerating evaporation bin 15 and the refrigerating evaporator 5 are used for refrigerating the refrigerating chamber 120 alone, and the humidity of the air in the refrigerating chamber 120 is mainly condensed on the refrigerating evaporator 5.

Referring to fig. 11, in some embodiments, when the amount of frost on the refrigeration evaporator 5 increases and it is desired to defrost the refrigeration evaporator 5, the baffle 16 may be closed, the refrigeration fan 17 may be opened, and the compressor 2 may be stopped. At this time, the refrigerating wind is circulated and opened, the frost on the refrigerating evaporator 5 can be utilized to continuously refrigerate the refrigerating chamber 120, and the refrigerating evaporator 5 is defrosted by the heat in the air in the refrigerating chamber 120, and the moisture on the refrigerating evaporator 5 can enter the refrigerating chamber 120 to humidify the refrigerating chamber 120 while defrosting, so that the inside of the refrigerating chamber 120 is refrigerated and moisturized. The defrosting mode can also greatly reduce the power consumption of the refrigerator.

It should be noted that, in other embodiments, the refrigeration system in fig. 12 may also be used in the refrigerator embodiments of fig. 3 to 6.

In this freezing cycle, the humidity in the air in the freezing chamber 110 is preferentially condensed on the refrigerating evaporator 5, and the amount of frost on the freezing evaporator 4 can be greatly reduced, so that the defrosting time of the freezing evaporator 4 is greatly reduced, the power consumption of the refrigerator is reduced, and the temperature fluctuation of the freezing chamber 110 is reduced.
