The refrigerator 100 of the present embodiment is described in detail below with reference to fig. 1 and 2.
The refrigerator 100 of the present embodiment includes a box, a condenser 14, and a valve assembly, in which a temperature-changing chamber 110, a freezing chamber 120, and a refrigerating chamber 130 are defined, the refrigerator 100 further includes a temperature-changing dew-removing pipe 15, a freezing dew-removing pipe 16, and a refrigerating dew-removing pipe 17 connected to an output end of the condenser 14, and the valve assembly is disposed on a refrigerant conveying line between the output end of the condenser 14 and the temperature-changing dew-removing pipe 15, the freezing dew-removing pipe 16, and the refrigerating dew-removing pipe 17, and configured to adjust a flow path of a refrigerant at the output end of the condenser 14 to the temperature-changing dew-removing pipe 15, the freezing dew-removing pipe 16, and the refrigerating dew-removing pipe 17 according to a set temperature of the temperature-changing chamber 110.
In the embodiment, the temperature-changing dew-removing pipe 15, the freezing dew-removing pipe 16 and the refrigerating dew-removing pipe 17 which are independently distributed are arranged, the valve assembly is additionally arranged on the refrigerant pipeline between the output end of the condenser 14 and the temperature-changing dew-removing pipe 15, the freezing dew-removing pipe 16 and the refrigerating dew-removing pipe 17, and the flow paths of the refrigerant among the temperature-changing dew-removing pipe 15, the freezing dew-removing pipe 16 and the refrigerating dew-removing pipe 17 are adjusted by the valve assembly according to the set temperature of the temperature-changing chamber 110, so that different temperature requirements on the temperature-changing dew-removing pipe 15 at different set temperatures of the temperature-changing chamber 110 can be met, and the dew-removing effect is improved.
The temperature-varying chamber 110, the freezing chamber 120, and the refrigerating chamber 130 generally have article access openings with open front sides, and the temperature-varying dew-removing pipe 15, the freezing dew-removing pipe 16, and the refrigerating dew-removing pipe 17 may be fitted in the outer peripheral side of the article access opening of the temperature-varying chamber 110, the outer peripheral side of the article access opening of the freezing chamber 120, and the outer peripheral side of the article access opening of the refrigerating chamber 130, respectively. The outer peripheral side of the article access opening is commonly called a door frame, that is, an area abutted against the door body when the door body is closed.
In the first embodiment, the valve assembly includes a first switching valve 18 and a first cutoff valve 19, an input of the first switching valve 18 is connected to an output of the condenser 14, and the first switching valve 18 has a first output connected to an input of the freezing dewing pipe 16 and a second output connected to an input of the temperature varying dewing pipe 15.
The first outlet end of the freezing dew-removing pipe 16 and the first outlet end of the temperature-changing dew-removing pipe 15 are both connected with the input end of a first stop valve 19, and the first inlet end of the refrigerating dew-removing pipe 17 is connected with the output end of the first stop valve 19.
When the set temperature of the variable temperature chamber 110 is in the temperature regulation interval of the freezing chamber 120, the first switching valve 18 is controlled to open the first output end and the second output end thereof, and the first cut-off valve 19 is controlled to open, so that the refrigerant at the output end of the condenser 14 simultaneously flows through the freezing dew-removing pipe 16 and the variable temperature dew-removing pipe 15, and then enters the refrigerating dew-removing pipe 17.
In the present embodiment, the set temperature of the variable temperature chamber 110 and the set temperature of the freezing chamber 120 are in the same temperature regulation range, that is, the variable temperature chamber 110 is set to be used as the freezing chamber 120 at this time, and the leakage cooling of the variable temperature chamber 110 in the leakage cooling region (generally, the region between the door body and the door frame of the variable temperature chamber 110) is substantially the same as the leakage cooling temperature of the freezing chamber 120, and therefore, the amount of heat required for the freezing chamber 120 and the variable temperature chamber 110 to balance the temperatures of the leakage cooling regions is also substantially the same.
For this reason, in the refrigerator 100 of the present embodiment, by additionally providing the first switching valve 18 and the first cut-off valve 19, the refrigerant discharged from the output end of the condenser 14 flows through the temperature-varying dew-removing pipe 15, the freezing dew-removing pipe 16, and the refrigerating dew-removing pipe 17 at the same time, so that more heat required by the temperature-varying chamber 110 and the freezing chamber 120 as the balanced cold leakage area is satisfied, and relatively less heat required by the refrigerating chamber 130 as the balanced cold leakage area is satisfied, thereby ensuring the dew-removing effect of the temperature-varying chamber 110, the freezing chamber 120, and the refrigerating chamber 130.
In the second embodiment, the valve assembly comprises a first switching valve 18, a first cutoff valve 19 and a second cutoff valve 20, the input of the first switching valve 18 being connected to the output of the condenser 14, the first switching valve 18 having a first output connected to the input of the freeze dew removal pipe 16 and a second output connected to the input of the temperature swing dew removal pipe 15.
The first outlet end of the freezing dew-removing pipe 16 and the first outlet end of the temperature-changing dew-removing pipe 15 are both connected with the input end of a first stop valve 19, and the first inlet end of the refrigerating dew-removing pipe 17 is connected with the output end of the first stop valve 19.
The input end of the second stop valve 20 is connected with the second outlet end of the freezing dew-removing pipe 16, and the output end of the second stop valve 20 is connected with the second inlet end of the refrigerating dew-removing pipe 17; and the first outlet end of the freezing dew-point elimination pipe 16 and the first outlet end of the temperature-changing dew-point elimination pipe 15 are communicated with the upstream of the input end of the first stop valve 19.
When the set temperature of the temperature-varying chamber 110 is within the temperature regulation range of the freezing chamber 120, the first switching valve 18 is controlled to open the first output end and the second output end, the first stop valve 19 is controlled to open, and the second stop valve 20 is controlled to close, so that the refrigerant at the output end of the condenser 14 flows through the freezing dew-removing pipe 16 and the temperature-varying dew-removing pipe 15 respectively, and then enters the refrigerating dew-removing pipe 17.
When the set temperature of the temperature changing chamber 110 is lower than the temperature of the freezing chamber 120, the first switching valve 18 is controlled to open the second outlet end thereof and close the first outlet end thereof, the first stop valve 19 is controlled to close, and the second stop valve 20 is controlled to open, so that the refrigerant flows through the temperature changing dew removing pipe 15, then flows through the freezing dew removing pipe 16, and then enters the refrigerating dew removing pipe 17.
The temperature-varying chamber 110 of the embodiment can be switched between a temperature regulation interval lower than the freezing chamber 120 and a temperature interval the same as the freezing chamber 120, the temperature-varying amplitude of the temperature-varying chamber 110 is increased, and the temperature-varying chambers 110 with two different temperature intervals are matched with two different refrigerant dew removing paths, so that dew removing effects of the temperature-varying chambers 110 with two different temperature intervals are ensured, and dew removing effects of the freezing chamber 120 and the refrigerating chamber 130 are ensured.
In this embodiment, when the set temperature of the variable temperature chamber 110 and the set temperature of the freezing chamber 120 are in the same temperature regulation zone, the temperature leakage of the variable temperature chamber 110 in the cold leakage region (generally, the region between the door body and the door frame of the variable temperature chamber 110) is substantially the same as the temperature leakage of the freezing chamber 120.
Therefore, the amounts of heat required for the freezing chamber 120 and the warming chamber 110 to balance the temperatures of the cold leakage areas are substantially the same, and the refrigerant discharged from the output end of the condenser 14 flows through the warming dew-removing tube 15, the freezing dew-removing tube 16, and the refrigerating dew-removing tube 17 at the same time by controlling the opening and closing of the first switching valve 18, the first stop valve 19, and the second stop valve 20, thereby satisfying more heat required for the warming chamber 110 and the freezing chamber 120 to balance the cold leakage areas, and ensuring the dew-removing effect of each chamber.
In this embodiment, when the set temperature of the variable temperature chamber 110 is lower than the temperature of the freezing chamber 120, the set temperature of the variable temperature chamber 110 is the lowest, and the variable temperature chamber 110 forms a lower temperature than the cold leakage of the freezing chamber 120 in the cold leakage area (generally, the area between the door body and the door frame of the variable temperature chamber 110).
Therefore, more heat is required to balance the temperature of the cold leakage area. Therefore, in the refrigerator 100 of the present embodiment, by controlling the opening and closing of the first switching valve 18, the first stop valve 19, and the second stop valve 20, the refrigerant discharged from the output end of the condenser 14 flows through the temperature-varying dew-removing pipe 15, and then sequentially flows through the freezing dew-removing pipe 16 and the refrigerating dew-removing pipe 17, so that more heat required by the temperature-varying chamber 110 as a balanced cold leakage area is satisfied, and heat required by the freezing chamber 120 and the refrigerating chamber 130 as a balanced cold leakage area is also satisfied, thereby ensuring the dew-removing effect of each chamber.
The first outlet end of the freezing dew-removing pipe 16 and the first outlet end of the temperature-changing dew-removing pipe 15 are connected to the input end of the first stop valve 19, and the implementation structure may specifically be: the first outlet end of the freezing dew-removing pipe 16 is connected with a first refrigerating pipe section (not numbered), the first outlet end of the temperature-changing dew-removing pipe 15 is connected with a second refrigerating pipeline (not numbered), the input end of the first stop valve 19 is connected with a third refrigerating pipeline (not numbered), the third refrigerating pipeline is provided with two inlet ends which are respectively connected with the first refrigerating pipeline and the second refrigerating pipeline, and therefore the first outlet end of the freezing dew-removing pipe 16 and the first outlet end of the temperature-changing dew-removing pipe 15 are indirectly connected with the input end of the first stop valve 19.
In the third embodiment, the valve assembly includes a first switching valve 18, a first cutoff valve 19, a second cutoff valve 20, and a third cutoff valve 21, an input end of the first switching valve 18 is connected to an output end of the condenser 14, and the first switching valve 18 has a first output end connected to an input end of the freezing dew condensation removing pipe 16 and a second output end connected to an input end of the temperature changing dew condensation removing pipe 15.

The compressor plays a role in a refrigeration system mainly by absorbing low-temperature and low-pressure refrigerant vapor from the evaporator, and finally becoming high-temperature and high-pressure vapor after adiabatic compression of the compressor.
The condenser 14 functions in the refrigeration system to introduce high-temperature and high-pressure vapor in the compressor into the condenser 14, condense the refrigerant vapor at the same pressure, and dissipate the heat to the surrounding medium to turn the refrigerant vapor into high-pressure and low-temperature refrigerant cold liquid.
The capillary tube plays a role in a refrigeration system mainly by converting high-pressure low-temperature refrigerant cold liquid into low-temperature low-pressure refrigerant steam after the refrigerant cold liquid is subjected to intermediate enthalpy throttling in the capillary tube, and then sending the refrigerant steam into an evaporator.
The evaporator mainly boils low-temperature and low-pressure refrigerant vapor passing through the capillary tube under the condition of constant pressure of the evaporator, and the refrigerant vapor absorbs heat of surrounding media in the boiling process and finally becomes low-temperature and low-pressure dry saturated vapor of the refrigerant.
In summary, a dry saturated gas of a refrigerant in a refrigeration system is compressed into a high-temperature high-pressure superheated refrigerant vapor when passing through a compressor, the high-temperature high-pressure superheated refrigerant vapor enters a condenser 14 through an exhaust pipe of an expansion valve piston of the compressor, the high-temperature high-pressure refrigerant vapor is condensed into a high-pressure low-temperature liquid in the condenser 14, then the liquid enters a filter (not shown), the liquid passes through a capillary tube, the medium enthalpy throttling in the capillary tube is changed into a low-temperature low-pressure refrigerant vapor, then the low-temperature low-pressure refrigerant boils in an isobaric evaporator to absorb a large amount of external heat to become saturated vapor, a refrigeration process is realized, and finally the refrigerant is sucked by the compressor again to perform a cold cycle.
