Referring to fig. 2-4, embodiments of the present disclosure provide a liquid storage pack and a refrigerator including a refrigeration system including the liquid storage pack.

A schematic structural diagram of a refrigeration system of a refrigerator according to an embodiment of the present disclosure is shown in FIG. 2.

The embodiment provides a refrigerating system, the refrigerating system comprises a compressor 1, a condenser 2, a throttling device 3 and an evaporator 4, the evaporator 4 comprises a refrigerating chamber evaporator 41 and a freezing chamber evaporator 42, a liquid storage bag 5 is arranged between an outlet of the freezing chamber evaporator 42 and an air suction port of the compressor 1, wherein an air return pipe is arranged at the air suction port of the compressor 1, and the air return pipe is communicated with the liquid storage bag 5.

The high-temperature high-pressure gaseous refrigerant discharged by the compressor 1 is cooled by the condenser 2 and then becomes normal-temperature liquid refrigerant, the refrigerant enters the evaporator 4, enters the liquid storage bag 5 from the outlet of the evaporator 4, and flows into the air return port of the compressor 1 through the liquid storage bag 5. The refrigeration of the refrigerator is realized through the circulation process.

The refrigerator includes a cabinet defining a refrigerating space. The refrigerating system is arranged on the box body and used for refrigerating the refrigerating space.

A schematic structure of a liquid storage pack 5 according to an embodiment of the present disclosure is shown in fig. 3, where the liquid storage pack 5 includes a liquid storage pack body. The liquid storage bag is internally provided with a liquid storage cavity 51, the liquid storage bag 5 is internally provided with an air inlet 52 and an air outlet 53, the air inlet 52 and the air outlet 53 are both communicated with the liquid storage cavity 51, the air inlet 52 is higher than the air outlet 53, the air inlet 52 is communicated with the evaporator 4, and the air outlet 53 is communicated with an air return pipe of the compressor 1.

The refrigerant in the evaporator 4 flows into the liquid storage chamber 51 from the inlet 52, flows into the muffler through the outlet 53, and flows into the compressor 1 from the suction port of the compressor 1.

The density of the gaseous refrigerant is less than that of the liquid refrigerant, and the gaseous refrigerant gradually separates from the liquid refrigerant and moves above the liquid refrigerant. In the prior art, as shown in fig. 1, a liquid storage bag 100 has a structure that a refrigerant completes heat exchange in an evaporator 4, a gas-liquid refrigerant enters the liquid storage bag 100 from an outlet of the evaporator 4, is sprayed out through an outlet of a connecting pipe 20, and a gaseous refrigerant enters an air return pipe through an outlet 10 of the liquid storage bag, is liquefied in the air return pipe and flows back to a compressor 1, and is subjected to compression circulation; when the refrigerator stops running, the gaseous refrigerant in the evaporator 4 can continuously enter the liquid storage bag 100 through the oil return port 30, the gaseous refrigerant can form floating bubbles in the liquid refrigerant, the bubbles are broken to generate noise, the liquid refrigerant and lubricating oil in the liquid storage bag 100 can flow back to the evaporator 4 from the oil return port 30, and the liquid volume in the liquid storage bag 100 is released.

In this case, the inlet 52 is higher than the outlet 53, i.e. the refrigerant enters the liquid storage chamber 51 from above and flows out from below. In this way, the gas-liquid two-phase refrigerant gradually separates from the liquid refrigerant during the flow from the gas inlet 52 to the gas outlet 53, and there is no problem in that the gas refrigerant floats up from the liquid refrigerant to generate bubbles, and thus there is no problem in that the bubbles collapse to generate noise.

The air inlet 52 is located directly above the air outlet 53.

When the air inlet 52 is positioned right above the air outlet 53, the distance between the air inlet 52 and the air outlet 53 along the up-down direction is large, and the flow path of the gas-liquid two-phase refrigerant in the liquid storage cavity 51 is longest, which is more beneficial to the separation of the gaseous refrigerant and the liquid refrigerant.

Alternatively, the dimension of the liquid storage pack 5 in the up-down direction is larger than that in the horizontal direction to increase the distance between the air inlet 52 and the air outlet 53.

Optionally, the liquid storage bag 5 further includes an air inlet pipe 6, the air inlet pipe 6 is communicated between the air inlet 52 and the evaporator 4, and one end of the air inlet pipe 6 extends into the liquid storage cavity 51.

The end of the portion of the air inlet pipe 6 extending into the liquid storage cavity 51 is provided with a jet hole 611, the gas-liquid two-phase refrigerant flows out from the evaporator 4, reaches the liquid storage cavity 51 through the jet hole 611 of the air inlet pipe 6, and the air inlet pipe 6 plays a role in transporting the gas-liquid two-phase refrigerant.

The wall of the liquid storage cavity 51 comprises a first cavity wall section 511, and the end of the air inlet pipe 6 positioned in the liquid storage cavity 51 is inclined towards the first cavity wall section 511 to form a first air inlet section 61.

The air inlet pipe 6 is inclined towards the first cavity wall section 511 at the end part to form a bending structure, so that when the spraying speed of the gas-liquid two-phase refrigerant sprayed from the spraying hole 611 is high, the gas-liquid two-phase refrigerant can be sprayed onto the first cavity wall section 511, the spraying speed of the gas-liquid two-phase refrigerant can be reduced, the descending speed of the gas-liquid two-phase refrigerant in the liquid storage cavity 51 is slowed down, the time for separating the gas-liquid two-phase refrigerant is prolonged, the gas-phase refrigerant can be fully separated from the liquid-phase refrigerant, and the separation effect of the gas-phase refrigerant and the liquid-phase refrigerant is improved; and noise caused by high-speed ejection of the gas-liquid two-phase refrigerant from the ejection port 611 is avoided.

The air inlet pipe 6 comprises a first air inlet section 61 positioned in the liquid storage cavity 51 and a second air inlet section 62 positioned outside the liquid storage bag 5 body, and the communication part of the second air inlet section 62 and the first air inlet section 61 forms a bending.

The bending can increase the flow resistance of the gas-liquid two-phase refrigerant in the air inlet pipe 6, thereby reducing the flow speed of the gas-liquid two-phase refrigerant in the air inlet pipe 6, reducing the ejection speed of the gas-liquid two-phase refrigerant from the ejection port 611, improving the separation effect of the gas-phase refrigerant and the liquid-phase refrigerant, and avoiding the noise caused by the high-speed ejection of the gas-liquid two-phase refrigerant from the ejection port 611.

The air inlet pipe 6 further comprises a third air inlet section 63 located outside the body of the liquid storage bag 5.

The third intake section 63, the second intake section 62, and the first intake section 61 are provided in this order along the flow direction of the refrigerant in the intake pipe 6. The communication between the third air intake section 63 and the second air intake section 62 forms a first bend.

The first bend can increase the flow resistance when the gas-liquid two-phase refrigerant flows from the third air inlet section 63 into the second air inlet section 62, thereby reducing the flow speed of the gas-liquid two-phase refrigerant in the air inlet pipe 6, reducing the ejection speed of the gas-liquid two-phase refrigerant from the ejection port 611, improving the separation effect of the gas-phase refrigerant and the liquid-phase refrigerant, and avoiding the noise caused by the high-speed ejection of the gas-liquid two-phase refrigerant from the ejection port 611.

Optionally, the liquid storage bag 5 further includes an air outlet pipe 7, the air outlet pipe 7 is communicated between the air outlet 53 and the air return pipe, and one end of the air outlet pipe 7 extends into the liquid storage cavity 51, and a portion of the air outlet pipe 7 located in the liquid storage cavity 51 is provided with an air inlet 711.

The gaseous refrigerant phase-separated from the gas-liquid two-phase refrigerant directly enters the muffler through the gas inlet 711 of the gas outlet pipe 7, so that the noise caused by the gaseous refrigerant floating up from the liquid refrigerant due to the gaseous refrigerant entering the bottom of the liquid storage cavity 51 can be avoided. One end of the air outlet pipe 7 extends into the liquid storage cavity 51, and the air inlet 711 of the air outlet pipe 7 is at a certain distance from the bottom of the liquid storage cavity 51, so that the bottom of the liquid storage cavity 51 can store a certain amount of liquid refrigerant.

An oil return port 72 is arranged on the pipe wall of the air outlet pipe 7, which is positioned in the liquid storage cavity 51, and the oil return port 72 penetrates through the pipe wall of the air outlet pipe 7 and is lower than the gas inlet 711. Fig. 4 is an enlarged partial schematic view of the return port 72 of fig. 3 provided in an embodiment of the present disclosure.

The number of the oil return ports 72 may be one or a plurality.

When the number of the oil return ports is plural, the plurality of oil return ports 72 may be arranged at intervals in sequence along the circumferential direction of the air outlet pipe 7, or may be arranged at intervals in sequence along the length direction of the air return pipe.

The oil return port 72 may have a circular shape or a rectangular shape.

The size, number and shape of the oil return ports 72 can be flexibly set according to practical applications, and are all within the scope of the present application.

After the gaseous refrigerant is separated from the liquid refrigerant, since the density of the gaseous refrigerant is smaller than that of the liquid refrigerant and the gas inlet 711 is higher than the return oil liquid return port 72, the gaseous refrigerant flows out from the gas inlet 711 to the return air pipe through the air outlet pipe 7, and the liquid refrigerant flows out from the return oil liquid return port 72 to the return air pipe through the air outlet pipe 7. I.e. the gaseous refrigerant and the liquid refrigerant flow from different ports (gas inlet port 711 and return oil return port 72, respectively) into the outlet pipe 7, avoiding noise generated by mixing the gaseous refrigerant and the liquid refrigerant.

The liquid refrigerant falls or flows to the bottom of the liquid storage bag 5 to form liquid accumulated liquid, and the liquid accumulated liquid and lubricating oil flow to the air return pipe from the oil return port 72. The arrangement position of the oil return port 72 ensures that the liquid level in the liquid storage cavity 51 is lower than the lowest liquid level of the height of the gas inlet 711 of the gas outlet pipe 7 when the evaporator 4 is in a refrigerating state.

When the oil return liquid return port 72 is specifically provided, the oil return liquid return port 72 needs to be arranged on the pipe wall of the air outlet pipe 7 close to the air outlet 53 of the liquid storage bag 5, so that liquid accumulated liquid in the liquid storage cavity 51 can completely flow to the air return pipe from the oil return liquid return port 72, and the phenomenon that the oil return liquid return port 73 is provided too close to the air inlet 711 of the air outlet pipe 7, so that abnormal noise in the liquid storage bag 5 is aggravated and the liquid accumulated liquid remained in the liquid storage cavity 51 is excessively high is avoided.

The liquid refrigerant directly enters the air return pipe from the oil return liquid return port 72, so that the cooling stroke of the refrigerant in the air return pipe can be reduced, the length of the air return pipe is shortened to a certain extent, and the design cost is reduced.

The cavity wall of the liquid storage cavity 51 further comprises a second cavity wall section 512 which is arranged opposite to the first cavity wall section 511, the end part of the air outlet pipe 7 positioned in the liquid storage cavity 51 is inclined towards the second cavity wall section 512 to form an air outlet section 71, and the air inlet 711 is arranged in the air outlet section.

The first and second chamber wall sections 511 and 512 are disposed opposite to each other such that the inclination directions of the first and second inlet and outlet sections 61 and 71 are opposite to each other, as shown in fig. 3, the first and outlet sections 61 and 71 are inclined opposite to each other, and the opposite inclination increases the distance between the first and outlet sections 61 and 71 compared to the opposite arrangement of the first and outlet sections 61 and 71, thereby increasing the distance of the gaseous refrigerant flowing into the gas inlet 711 from the discharge port 611, so that the gaseous refrigerant can be sufficiently separated from the liquid refrigerant.

Alternatively, the ejection port 611 is higher than the gas inlet 711.

The scheme can ensure that the gaseous refrigerant separated from the gas-liquid two-phase refrigerant sprayed from the spraying hole 611 directly enters the air return pipe from the gas inlet 711, and can avoid noise caused by the fact that the gaseous refrigerant is lower than the gas inlet 711 in the spraying hole 611 and enters liquid accumulated liquid at the bottom of the liquid storage cavity 5.

An embodiment of the second aspect of the present application provides a refrigerator comprising a compressor 1, an evaporator 4 and a liquid storage pack 5 according to any of the above embodiments, the liquid storage pack 5 being in communication between an air suction port of the compressor 1 and an outlet of the evaporator 4.

The refrigerator provided in the embodiment of the second aspect of the present application, because of including the liquid storage pack 5 according to any one of the above embodiments, has all the advantages of the liquid storage pack 5 according to any one of the above embodiments, and will not be described in detail herein.

With this receiver 5, the gas-liquid two-phase refrigerant flowing into the receiver 5 from the outlet of the evaporator 4 after phase separation does not enter the receiver 51 from below and flow out from above, so there is no case where the gaseous refrigerant floats up from the liquid refrigerant to generate bubbles. According to the scheme, the refrigerant can enter the liquid storage cavity from the upper air inlet 52 and flow out from the lower air outlet 53, the gaseous refrigerant is gradually separated from the liquid refrigerant, and compared with the problem that bubbles are broken to form noise in the prior art, the problem that the gaseous refrigerant in the gas-liquid two-phase refrigerant can form floating bubbles is avoided, and noise is reduced.
