[0071] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0072] A refrigerator is a refrigeration device that maintains a constant low temperature. It is also a civilian product that keeps food or other items at a constant low temperature.

[0073] The refrigeration structure of the refrigerator is mainly composed of a compressor, a condenser, a throttle valve and an evaporator which are connected end to end in sequence, wherein the compressor, the condenser, the throttle valve and the evaporator are connected by a connecting pipe, and a refrigerant is circulated in the compressor, the condenser, the throttle valve, the evaporator and the connecting pipe.

[0074] It should be noted that the fluid movement of the refrigerant is shown in the following steps:

[0075] Step 1: Low-temperature and low-pressure refrigerant gas comes out of the evaporator and enters the inlet of the compressor. The compressor compresses the refrigerant gas into high-temperature and high-pressure gas, which is then discharged through the outlet.

[0076] Step 2: High-temperature and high-pressure refrigerant gas comes out of the compressor and enters the inlet of the condenser. In the condenser, the refrigerant gas dissipates heat through the heat sink and fan, gradually cools and condenses into high-pressure liquid. The condensed high-pressure liquid refrigerant flows out from the outlet of the condenser.

[0077] Step 3: High-pressure liquid refrigerant comes out of the condenser and enters the inlet of the throttle valve. In the throttle valve, the refrigerant liquid passes through a small hole or expansion device, the pressure drops suddenly, and it expands rapidly and becomes a low-temperature and low-pressure liquid.

[0078] Step 4: The low-temperature and low-pressure liquid refrigerant comes out of the throttle valve and enters the inlet of the evaporator. In the evaporator, the refrigerant absorbs the heat inside the refrigerator and gradually evaporates into gas. This process causes the temperature inside the refrigerator to drop. The evaporated low-temperature and low-pressure refrigerant gas flows out from the outlet of the evaporator.

[0079] Step 5: The evaporated low-temperature and low-pressure refrigerant gas enters the inlet of the compressor again through the connecting pipe.

[0080] It should be noted that the temperature of the surface of the evaporator is lower than the internal temperature of the refrigerator, and heat exchange occurs between the surface of the evaporator and the interior of the refrigerator, causing the internal temperature of the refrigerator to drop.

[0081] In the related art, the refrigerator is provided with a refrigerating chamber, a temperature-changing chamber and a freezing chamber, wherein the temperature of the refrigerating chamber is greater than or equal to the temperature of the temperature-changing chamber, and the temperature of the temperature-changing chamber is greater than the temperature of the freezing chamber. The setting of the refrigerating chamber, the temperature-changing chamber and the freezing chamber can enable the refrigerator to better meet the family's storage needs for various foods and improve the preservation effect and storage efficiency of food.

[0082] It should be noted that in the related art, the evaporator is arranged in the refrigerator body, and the surface temperature of the evaporator is lower than the internal temperature of the body. The evaporator exchanges heat with the air inside the body, which will drive the internal temperature of the body to drop and cause the cold energy of the evaporator to flow to the external environment, thereby leading to the problem of low utilization rate of the cold energy of the evaporator.

[0083] like Figure 1 and Figure 2 As shown, an embodiment of the present application provides a refrigerator, which includes: a box body 100, a first evaporator 200 and at least one connecting piece 300. The box body 100 is formed with a first installation cavity 101 and a second installation cavity 102, and the first installation cavity 101 and the second installation cavity 102 are arranged at intervals; the first evaporator 200 is arranged in the first installation cavity 101; the connecting piece 300 is arranged on the box body 100, one end of the connecting piece 300 is connected to the first installation cavity 101, and the other end of the connecting piece 300 is connected to the second installation cavity 102.

[0084] It should be noted that the cold energy generated by the first evaporator 200 can be driven by the first external force and then guided to the connecting piece 300 through the first installation cavity 101 , and then guided to the second installation cavity 102 through the connecting piece 300 .

[0085] like Figure 3 and Figure 4 As shown, it should be noted that the connecting piece 300 is used to connect the first installation cavity 101 and the second installation cavity 102 ; the air inside the first installation cavity 101 and the second installation cavity 102 can circulate through the connecting piece 300 .

[0086] It is understandable that the surface temperature of the first evaporator 200 is lower than the internal temperature of the first installation cavity 101, and heat exchange occurs between the surface of the first evaporator 200 and the first installation cavity 101, so that the internal temperature of the first installation cavity 101 is reduced. The first installation cavity 101 is used to isolate the first evaporator 200 from direct contact with the outside world, thereby reducing the flow of cold generated by the first evaporator 200 toward the outside world, thereby keeping the first evaporator 200 cold.

[0087] Thus, the internal temperature of the first installation cavity 101 is lower than the internal temperature of the second installation cavity 102. The first installation cavity 101 and the second installation cavity 102 are connected by the connecting piece 300. The first installation cavity 101 and the second installation cavity 102 generate heat exchange through the connecting piece 300, so that the internal temperature of the second installation cavity 102 is reduced. The setting of the second installation cavity 102 can reduce the coldness in the second installation cavity 102 from flowing to the outside.

[0088] Therefore, the refrigerator provided in the embodiment of the present application can solve the problem of low utilization rate of the cooling capacity of the evaporator.

[0089] The refrigerator provided in the embodiment of the present application further includes: a first fan, which is arranged on the box body 100;

[0090] The air inlet end of the first fan is arranged toward the first installation cavity 101 , and the air outlet end of the first fan is arranged toward the connecting piece 300 .

[0091] It is understandable that the first fan is used to accelerate the air in the first installation cavity 101 to move toward the connecting piece 300 , and drive the cold energy in the first installation cavity 101 to flow toward the connecting piece 300 , so as to improve the cold energy utilization rate of the first evaporator 200 .

[0092] like Figure 5As shown, the refrigerator provided in the embodiment of the present application also includes: a first chamber 103 and a second chamber 104; wherein, the first chamber 103 is located on the side of the box body 100 close to the box opening, and the first chamber 103 is connected to the first installation cavity 101; the second chamber 104 is located on the side of the box body 100 close to the box opening, and the second chamber 104 is connected to the second installation cavity 102.

[0093] like Figure 6 As shown, it should be noted that the first chamber 103 and the second chamber 104 have a variety of different configurations. The specific configurations of the first chamber 103 and the second chamber 104 are described below with examples.

[0094] In a feasible implementation manner, the first chamber 103 is a temperature-changing chamber, and the second chamber 104 is a refrigerating chamber.

[0095] like Figure 7 As shown, in another feasible implementation manner, the first chamber 103 is a freezing chamber, and the second chamber 104 is a refrigerating chamber.

[0096] In addition, in other feasible implementations, the first chamber 103 is a freezing chamber, and the second chamber 104 is a temperature-changing chamber.

[0097] It is understandable that there is no limitation on the specific configuration of the first chamber 103 and the second chamber 104 , and they can be selected according to actual use requirements, as long as the internal temperature of the first chamber 103 is less than or equal to the internal temperature of the second chamber 104 .

[0098] It should be noted that a first channel is arranged between the first installation cavity 101 and the first chamber 103, one end of the first channel is connected to the first installation cavity 101, and the other end of the first channel is connected to the first chamber 103; the air in the first installation cavity 101 can be guided to the interior of the first chamber 103 after passing through the first channel, wherein the internal temperature of the first installation cavity 101 is lower than the internal temperature of the first chamber 103, and heat exchange is generated between the first chamber 103 and the first installation cavity 101, so that the internal temperature of the first chamber 103 is reduced.

[0099] It should be noted that a second channel is arranged between the second installation cavity 102 and the second chamber 104, one end of the second channel is connected to the second installation cavity 102, and the other end of the second channel is connected to the second chamber 104; the air in the second installation cavity 102 can be guided to the interior of the second chamber 104 after passing through the second channel, wherein the internal temperature of the second installation cavity 102 is lower than the internal temperature of the second chamber 104, and heat exchange is generated between the second chamber 104 and the second installation cavity 102, so that the internal temperature of the second chamber 104 is reduced.

[0100] It should be noted that there are many different connection modes between the first chamber 103 and the second chamber 104 . The connection modes between the first chamber 103 and the second chamber 104 are described below in turn with examples.

[0101] In a feasible implementation manner, the first chamber 103 and the second chamber 104 are spaced apart from each other.

[0102] In another possible implementation, the first chamber 103 and the second chamber 104 are disposed adjacent to each other.

[0103] In addition, in another feasible embodiment, the first chamber 103 and the second chamber 104 are connected, and the first chamber 103 and the second chamber 104 are connected through a connecting pipe, one end of the connecting pipe is connected to the first chamber 103, and the other end of the connecting pipe is connected to the second chamber 104.

[0104] It is understandable that there is no limitation on the connection method between the first chamber 103 and the second chamber 104 , and it can be selected according to actual use requirements.

[0105] The refrigerator provided in the embodiment of the present application also includes: a second fan 400, which is arranged on the box body 100, the air inlet end of the second fan 400 is arranged toward the first installation cavity 101, and the air outlet end of the second fan 400 is arranged to be connected to the first chamber 103, and the second fan 400 is used to drive the cold air in the first installation cavity 101 into the first chamber 103.

[0106] It should be noted that the second fan 400 is used to speed up the air circulation between the first installation cavity 101 and the first chamber 103 , thereby speeding up the movement of the cold energy in the first installation cavity 101 toward one side of the first chamber 103 .

[0107] like Figure 8 As shown, the refrigerator provided in the embodiment of the present application also includes: a third fan 500, the third fan 500 is arranged on the box body 100, the air inlet end of the third fan 500 is connected to the second installation cavity 102, and the air outlet end of the third fan 500 is connected to the second chamber 104, and the third fan 500 is used to drive the cold air in the second installation cavity 102 into the second chamber 104.

[0108] It should be noted that the third fan 500 is used to speed up the air circulation between the second installation cavity 102 and the second chamber 104 , thereby speeding up the movement of the cold energy in the second installation cavity 102 toward one side of the second chamber 104 .

[0109] The connecting piece 300 provided in the embodiment of the present application includes: an air inlet 301 and an air outlet 302, and the air inlet 301 and the air outlet 302 are arranged at intervals; the air inlet 301 is used to guide the air in the first installation cavity 101 to the second installation cavity 102; the air outlet 302 is used to guide the air in the second installation cavity 102 to the first installation cavity 101.

[0110] It should be noted that the air in the first installation cavity 101 can enter the second installation cavity 102 through the air inlet 301 , and the air in the second installation cavity 102 can enter the first installation cavity 101 through the air outlet 302 .

[0111] It is understandable that the setting of the air inlet 301 and the air outlet 302 can increase the air circulation speed between the first installation cavity 101 and the second installation cavity 102, thereby improving the heat exchange speed between the first installation cavity 101 and the second installation cavity 102, thereby reducing the cooling time of the second installation cavity 102.

[0112] It should be noted that the connecting piece 300 has a variety of different configurations, and the configurations of the connecting piece 300 are described below in turn with examples.

[0113] In a feasible embodiment, the connecting piece 300 is a connecting tube, one end of the connecting tube is connected to the first installation cavity 101, and the other end of the connecting tube is connected to the second installation cavity 102. The connection between the connecting tube and the first installation cavity 101 forms an air inlet 301, and the connection between the connecting tube and the second installation cavity 102 forms an air outlet 302.

[0114] It can be understood that the provision of the connecting pipe can guide the cold air in the first installation cavity 101 to the second installation cavity 102 , so that the internal temperature of the second installation cavity 102 is reduced.

[0115] In another feasible embodiment, the connecting piece 300 is a connecting hole, which is opened between the first installation cavity 101 and the second installation cavity 102, one end of the connecting hole is connected to the first installation cavity 101, and the other end of the connecting hole is connected to the second installation cavity 102, and the connection between the connecting hole and the first installation cavity 101 forms an air inlet 301, and the connection between the connecting hole and the second installation cavity 102 forms an air outlet 302.

[0116] It is understandable that the provision of the connecting hole can reduce the difficulty of connecting the first installation cavity 101 and the second installation cavity 102 , and can guide the cold air in the first installation cavity 101 to the second installation cavity 102 , so as to reduce the internal temperature of the second installation cavity 102 .

[0117] It is understandable that there is no limitation on the configuration of the connecting piece 300 , and it can be selected according to actual use requirements, as long as the connecting piece 300 can connect the first installation cavity 101 and the second installation cavity 102 .

[0118] It should be noted that a plurality of connecting pieces 300 are provided, and two adjacent connecting pieces 300 are arranged at intervals.

[0119] It is understandable that providing a plurality of connecting pieces 300 can increase the air circulation speed between the first installation cavity 101 and the second installation cavity 102 , thereby increasing the heat exchange speed between the first installation cavity 101 and the second installation cavity 102 , thereby reducing the cooling time of the second installation cavity 102 .

[0120] It should be noted that there are many different ways to set the number of connecting pieces 300. The following will illustrate the number of connecting pieces 300 in turn with examples.

[0121] In a feasible implementation manner, one connecting piece 300 is provided, and the connecting piece 300 is respectively connected to the first installation cavity 101 and the second installation cavity 102 .

[0122] In another feasible implementation manner, two connecting pieces 300 are provided, and the two connecting pieces 300 are respectively connected to the first installation cavity 101 and the second installation cavity 102 , and the two connecting pieces 300 are spaced apart.

[0123] It is understandable that there is no limit to the number of connecting pieces 300 that can be set, and it can be selected according to actual usage requirements. It only needs to ensure that the connecting pieces 300 can be connected to the first installation cavity 101 and the second installation cavity 102 respectively.

[0124] It is understandable that increasing the number of the connecting pieces 300 can increase the connecting area between the first installation cavity 101 and the second installation cavity 102 , thereby increasing the air circulation speed between the first installation cavity 101 and the second installation cavity 102 .

[0125] like Fig. 9 As shown, the refrigerator provided in the embodiment of the present application further includes: a second evaporator 600 , and the second evaporator 600 is disposed in the second installation cavity 102 .

[0126] It is understandable that the surface temperature of the second evaporator 600 is lower than the internal temperature of the second installation cavity 102, and heat exchange occurs between the surface of the second evaporator 600 and the second installation cavity 102, so that the internal temperature of the second installation cavity 102 is reduced, thereby reducing the cooling time of the second installation cavity 102.

[0127] It can be understood that the second evaporator 600 is arranged in the second installation cavity 102, and the second installation cavity 102 is used to isolate the second evaporator from direct contact with the outside world, so as to reduce the circulation of the cold energy generated by the second evaporator to the outside world, thereby keeping the second evaporator cold and improving the cold energy utilization rate of the second evaporator.

[0128] like Fig.10 As shown, the refrigerator provided in the embodiment of the present application further includes: a first temperature measuring member 700 and a second temperature measuring member 800.

[0129] It can be understood that the first temperature measuring element 700 is used to detect the internal temperature of the first chamber 103 , and the second temperature measuring element is used to detect the internal temperature of the second chamber 104 .

[0130] It should be noted that the first temperature measuring component 700 has a variety of different configurations. The configurations of the first temperature measuring component 700 are described below with examples.

[0131] In a feasible implementation manner, the first temperature measuring component 700 is a first temperature sensing probe. The first temperature sensing probe is at least partially located in the first chamber 103 , and the first temperature sensing probe is used to measure the internal temperature of the first chamber 103 .

[0132] In another feasible implementation manner, the first temperature measuring component 700 is a first infrared temperature sensor, which is located in the first chamber 103 and is used to measure the internal temperature of the first chamber 103 .

[0133] It is understandable that there is no limitation on the specific configuration of the first temperature measuring component 700 , and it can be selected according to actual use requirements, as long as the first temperature measuring component 700 can measure the internal temperature of the first chamber 103 .

[0134] It should be noted that the second temperature measuring component 800 has a variety of different configurations. The configurations of the second temperature measuring component 800 are described below with examples.

[0135] In a feasible implementation manner, the second temperature measuring component 800 is a second temperature sensing probe, which is at least partially located in the second chamber 104 , and is used to measure the internal temperature of the second chamber 104 .

[0136] In another feasible implementation manner, the second temperature measuring component 800 is a second infrared temperature sensor, which is located in the second chamber 104 and is used to measure the internal temperature of the second chamber 104 .

[0139] It can be understood that the surface temperature of the first evaporator 200 is lower than the internal temperature of the first installation cavity 101, and heat exchange occurs between the first installation cavity 101 and the surface of the first evaporator 200, so that the internal temperature of the first installation cavity 101 decreases; thus, the internal temperature of the first installation cavity 101 is lower than the internal temperature of the second installation cavity 102, and heat exchange occurs between the first installation cavity 101 and the second installation cavity 102, so that the internal temperature of the second installation cavity 102 decreases. The arrangement of the first installation cavity 101 and the second installation cavity 102 can isolate the first evaporator 200 from direct contact with the external environment, thereby keeping the first evaporator 200 cold.

[0140] Therefore, the refrigerator provided in the embodiment of the present application can solve the problem of low utilization rate of the cooling capacity of the evaporator.
