[0038] The embodiment of the present application provides a distributor, a refrigeration system and a refrigerator, so as to solve the problem that the freezing branch is usually in an open state when the ambient temperature is high in the existing double-system refrigerator, and the refrigeration demand of the refrigeration compartment is opened again, so that the temperature of the refrigeration compartment is difficult to pull down. The following will be described with reference to the accompanying drawings.

[0039] The distributor 1 provided by the embodiment of the present application is applied to a refrigerator. The refrigerator comprises a refrigeration compartment, a freezing evaporator 10 and a refrigeration evaporator 9. Please refer to Figures 1 to 3The distributor 1 comprises a shell 11, the shell 11 is formed with a communicating containing space 111 for containing refrigerant, a refrigerant inlet 112, a freezing outlet 113 and a refrigerating outlet 114, the freezing outlet 113 is communicated with the freezing evaporator 10, and the refrigerating outlet 114 is openably and closably connected with the refrigerating evaporator 9; the liquid level at the freezing outlet 113 is higher than the liquid level at the refrigerating outlet 114; wherein when the temperature of the refrigerating compartment is higher than a first preset temperature, the refrigerating outlet 114 is communicated with the refrigerating evaporator 9; when the temperature of the refrigerating compartment is lower than a second preset temperature, the refrigerating outlet 114 is disconnected with the refrigerating evaporator 9, and the first preset temperature is higher than the second preset temperature. The specific values of the first preset temperature and the second preset temperature are not limited herein.

[0040] The distributor 1 provided by the embodiment of the present application, because the liquid level at the freezing outlet 113 is higher than the liquid level at the refrigerating outlet 114, when the refrigerating branch and the freezing branch are opened at the same time, if the liquid level in the containing space 111 of the distributor 1 is lower than the liquid level at the freezing outlet 113, the refrigerant in the containing space 111 will flow to the refrigerating evaporator 9 from the refrigerating outlet 114, realizing the preferential supply to the refrigerating evaporator 9; if the liquid level in the containing space 111 of the distributor 1 is higher than the liquid level at the freezing outlet 113, because of the height difference of the liquid level between the refrigerating outlet 114 and the refrigerating outlet 114, the pressure at the refrigerating outlet 114 will be greater than the pressure at the freezing outlet 113, so the refrigerant flow at the refrigerating outlet 114 will be greater than the refrigerant flow at the freezing outlet 113, to realize the preferential supply to the refrigerating evaporator 9. That is, when the refrigerating outlet 114 is communicated with the refrigerating evaporator 9, the refrigerant in the distributor 1 can always realize the preferential supply to the refrigerating evaporator 9, preventing the migration loss caused by the migration of the refrigerant between the freezing branch and the refrigerating branch, and the problem of slow temperature drop of the refrigerating compartment caused by the small refrigerant supply amount of the refrigerating branch. Even in the state that the freezing branch is always opened under the high ambient temperature of the refrigerator, the refrigerant flow at the refrigerating outlet 114 can be greater than the refrigerant flow at the freezing outlet 113, to compensate for the migration loss of the refrigerant and ensure the temperature drop speed of the refrigerating compartment.

[0041] Optionally, referring to Figure 1 The distributor 1 provided by the embodiment of the present application further comprises a control valve 12, the control valve 12 is openably and closably arranged at the refrigerating outlet 114, for controlling the opening and closing of the refrigerating outlet 114. By arranging the control valve 12 at the refrigerating outlet 114, the openable and closable connection between the refrigerating outlet 114 and the refrigerating evaporator 9 is realized, and the control valve 12 is opened only when the refrigerating compartment has a refrigeration demand, so that the refrigerating outlet 114 and the refrigerating evaporator 9 are communicated, and the refrigeration effect on the refrigerating compartment is realized.

[0042] Optionally, the opening degree of the control valve 12 is adjustable. In some examples, the control valve 12 can be a solenoid valve, and the type of the solenoid valve is not limited herein.

[0043] Optionally, referring to Figure 1 and Figure 2 , the shell 11 extends along the direction of gravity, and the shell 11 is further provided with a freezing conduit 13 extending along the direction of gravity and at least partially located in the containing space 111, one end of the freezing conduit 13 located in the containing space 111 forms a freezing outlet 113; and a refrigeration outlet 114 is located at the bottom of the shell 11. That is, the distributor 1 can be vertically placed for use, at this time, the freezing conduit 13 can also be vertically arranged, specifically, the freezing conduit 13 can have a certain spacing from the top of the distributor 1, which not only meets the liquid level difference between the freezing outlet 113 and the refrigeration outlet 114, but also reduces the requirement for the refrigerant liquid level in the distributor 1 when the freezing compartment is refrigerated.

[0044] Further, part of the freezing conduit 13 can be arranged outside the distributor 1 so as to be connected with the freezing evaporator 10, specifically, the part of the freezing conduit 13 arranged outside the distributor 1 is first connected with the freezing capillary tube 5, and the other end of the freezing capillary tube 5 is connected with the freezing evaporator 10.

[0045] Optionally, referring to Figure 2 , the freezing conduit 13 is externally sleeved with a movable sleeve 131, and the movable sleeve 131 is movable along the axial direction of the freezing conduit 13. By sleeving the movable sleeve 131 on the external periphery of the freezing conduit 13, the height of the freezing outlet 113 can be adjusted by controlling the movable sleeve 131 to move along the axial direction of the freezing conduit 13, thereby changing the height difference between the freezing outlet 113 and the refrigeration outlet 114, so as to change the relative refrigerant flow at the freezing outlet 113 and the refrigeration outlet 114, for example, when the refrigeration compartment is overheated, the movable sleeve 131 can be appropriately raised to further reduce the pressure difference of the freezing outlet 113, so as to increase the pressure difference between the refrigeration outlet 114 and the freezing outlet 113, thereby increasing the refrigerant flow at the refrigeration outlet 114, and realizing the rapid temperature draw of the refrigeration compartment.

[0046] By sleeving the movable sleeve 131 on the external periphery of the freezing conduit 13, the length of the freezing conduit 13 can be set to be relatively short, so when the refrigeration compartment has no refrigeration requirement, the movable sleeve 131 is directly lowered to the minimum to form the freezing outlet 113 with the original opening of the freezing conduit 13, the height of the freezing outlet 113 is maximally reduced, so as to reduce the requirement for the refrigerant liquid level in the distributor 1 when the freezing compartment is refrigerated, at the same time, the height of the freezing outlet 113 is also reduced, which increases the pressure at the freezing outlet 113, thereby increasing the refrigerant flow at the freezing outlet 113, and facilitating the improvement of the refrigeration efficiency of the freezing compartment.

[0047] Optionally, the shell 11 is further provided with a refrigeration conduit 14 extending along the direction of gravity from the refrigeration outlet 114. The refrigeration conduit 14 is convenient to be connected with the refrigeration evaporator 9 by being arranged.

[0049] That is, the shell 11 can also be placed horizontally for use, which can be more convenient to assemble into the compressor 2 compartment, at this time, the refrigeration conduit 14 can be vertically arranged at the bottom of the shell 11 of the distributor 1, and the freezing conduit 13 can be arranged at one side of the shell 11, so as to realize the height difference setting of the refrigeration outlet 114 and the freezing outlet 113, without the need to extend the refrigeration conduit 14 or the freezing conduit 13 in the containing space 111, thereby reducing the manufacturing difficulty.

[0050] Further, the refrigeration conduit 14 includes a first pipe section, a transition pipe and a second pipe section, the first pipe section is connected with the shell 11, the transition pipe connects the first pipe section and the second pipe section, the inner diameter of the first pipe section is larger than that of the second pipe section, and the inner diameter of the first pipe section can be 6 mm, for example, so as to increase the refrigerant distribution amount of the refrigeration conduit 14. The second pipe section with a smaller inner diameter is arranged to communicate with the refrigeration capillary tube 6, that is, the second pipe section of the refrigeration conduit 14, the refrigeration capillary tube 6 and the refrigeration evaporator 9 are sequentially communicated. The transition pipe is used for the transition connection between the first pipe section and the second pipe section, and the shape of the transition pipe is not limited further, for example, the transition pipe can be a tapered pipe.

[0051] Optionally, the distributor 1 provided by the embodiment of the present application further comprises a liquid inlet pipe, one end of the liquid inlet pipe is in communication with the liquid inlet 112, and the other end is in communication with an upstream device of the distributor 1, such as a filter 4.
