The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
The utility model provides a cold-stored refrigeration device, figure 1 is according to the utility model discloses a cold-stored refrigeration device's of an embodiment schematic structure chart. Referring to fig. 1, the refrigerating and freezing device 1 of the present invention includes a box 10, wherein a plurality of storage compartments are defined in the box 10, and one of the storage compartments is a deep cooling compartment 131. Further, the refrigerating and freezing device 1 further comprises at least one door body for opening and closing the plurality of storage compartments. The refrigerating and freezing device 1 can be a refrigerator, a freezer, etc.
The cold-storage freezer 1 further comprises a compression refrigeration system 20 for cooling each storage compartment. Fig. 2 is a schematic structural view of a compression refrigeration system according to an embodiment of the present invention. Referring to FIG. 2, compressor refrigeration system 20 may include a compressor 21, a condenser 22, a freezing throttling element 232, a cryogenic throttling element 231, and a cryogenic evaporator 241 connected in series. Cryogenic evaporator 241 may be disposed within cryogenic compartment 131 or routed to cryogenic compartment 131 to provide cooling to cryogenic compartment 131. That is to say, the refrigeration and freezing device 1 of the present application realizes the cryogenic function of the cryogenic compartment 131 through the compression and refrigeration system 20, and the compression and refrigeration system 20 includes the freezing throttling element 232, the cryogenic throttling element 231 and the cryogenic evaporator 241 which are connected in series, the refrigerant flowing out of the condenser 22 flows to the cryogenic evaporator 241 after passing through the freezing throttling element 232 and the cryogenic throttling element 231 in sequence for secondary throttling, and the cryogenic compartment 131 is refrigerated through the cryogenic evaporator 241, so that the cryogenic storage function of lower temperature than the freezing temperature in the cryogenic compartment 131 is realized quickly and effectively with a very simple structure, and the complex structure and the great increase of the cost of the refrigeration and freezing device 1 are avoided.
Specifically, the compression refrigeration system further includes a first refrigerant pipeline 251, a second refrigerant pipeline 252 and a first valve 261. First refrigerant pipe 251 is connected in parallel with cryogenic throttling element 231 and cryogenic evaporator 241, that is, first refrigerant pipe 251 is connected in parallel at two ends of the refrigerant flow path where cryogenic throttling element 231 and cryogenic evaporator 241 are located. Second refrigerant line 252 is connected in parallel with cryogenic throttling element 231, i.e. second refrigerant line 252 is connected in parallel across cryogenic throttling element 231. First valve 261 is used for controlling the make-and-break of three refrigerant flow paths of cryogenic throttling element 231 and cryogenic evaporator 241, first refrigerant pipeline 251, and second refrigerant pipeline 252 and cryogenic evaporator 241. The three refrigerant flow paths have different on-off states, and the operation states of the cryogenic throttling element 231 and the cryogenic evaporator 241 are different, so that different storage temperature regions of the cryogenic compartment 131 can be realized when the different refrigerant flow paths are communicated, wide temperature change in the cryogenic compartment 131 is realized, the use function of the cryogenic compartment 131 is increased, the cryogenic compartment 131 has other storage functions besides the cryogenic function, different use requirements of users are met, and the application range is wide.
Specifically, the compressor 21 compresses the vaporized refrigerant into a high-temperature and high-pressure gas, and then discharges the gas from a discharge port of the compressor 21. An inlet of the condenser 22 is connected to an exhaust port of the compressor 21, and the high-temperature and high-pressure gaseous refrigerant passes through the condenser 22 and is gradually condensed into a high-pressure liquid while being radiated to the outside. The inlet of the freezing throttling element 232 is connected with the outlet of the condenser 22, and the high-pressure liquid refrigerant passes through the freezing throttling element 232 and then is reduced in pressure to become a gas-liquid mixture.
In some embodiments of the present disclosure, first valve 261 is configured to controllably selectively communicate one of the three refrigerant flow paths of cryogenic throttling element 231 and cryogenic evaporator 241, first refrigerant conduit 251, and second refrigerant conduit 252 and cryogenic evaporator 241. That is, first valve 261 may be controlled to conduct only the refrigerant flow path in which cryogenic throttling element 231 and cryogenic evaporator 241 are located, may be controlled to conduct only the refrigerant flow path in which first refrigerant pipe 251 is located, and may be controlled to conduct only the refrigerant flow path in which second refrigerant pipe 252 and cryogenic evaporator 241 are located. Therefore, the problem that the refrigerant flow distribution is uncontrollable possibly caused by the simultaneous conduction of any two or more refrigerant flow paths can be avoided, and the running stability of the refrigerating and freezing device 1 is improved.
In some embodiments of the present invention, the cryogenic compartment 131 has a freezing mode, a cryogenic mode, and a variable temperature mode.
In the freezing mode, the first valve 261 connects the second refrigerant pipe 252 and the refrigerant flow path where the cryogenic evaporator 241 is located, so that the refrigerant flows back to the compressor 21 after passing through the second refrigerant pipe 252 and the cryogenic evaporator 241. At this time, the refrigerant flowing out of the condenser 22 is once throttled by the freezing throttle element 232 and flows to the cryogenic evaporator 241, and therefore the cryogenic compartment 131 can be used as a normal freezing compartment.
In the cryogenic mode, first valve 261 may direct the refrigerant flow path through which cryogenic throttling element 231 and cryogenic evaporator 241 are located such that the refrigerant flows back to compressor 21 after passing through cryogenic throttling element 231 and cryogenic evaporator 241. At this time, the refrigerant flowing out of the condenser 22 flows to the cryogenic evaporator 241 after passing through the freezing throttling element 232 and the cryogenic throttling element 231 in sequence and throttling twice, so that more cold can be provided to the cryogenic compartment 131, the temperature in the cryogenic compartment is lower than that of the ordinary freezing compartment, and a cryogenic storage environment is formed.
In the temperature changing mode, the first valve 261 alternately connects the refrigerant flow path where the first refrigerant pipeline 251 is located and the refrigerant flow path where the second refrigerant pipeline 252 and the cryogenic evaporator 241 are located according to a preset time period, so that the refrigerant alternately flows back to the compressor 21 directly through the first refrigerant pipeline 251 or flows back to the compressor 21 after passing through the second refrigerant pipeline 252 and the cryogenic evaporator 241. When the first valve 261 is communicated with the refrigerant flow path where the first refrigerant pipeline 251 is located, the refrigerant directly flows back to the compressor 21 through the first refrigerant pipeline 251 without flowing through the cryogenic throttling element 231 and the cryogenic evaporator 241, and at this time, the cryogenic compartment 131 is hardly supplied with cold and does not refrigerate; when the first valve 261 conducts the refrigerant flow path where the second refrigerant pipeline 252 and the cryogenic evaporator 241 are located, the refrigerant flows to the cryogenic evaporator 241 after being throttled once only by the freezing throttling element 232, and at this time, the cryogenic chamber 131 serves as a common freezing chamber to perform refrigeration. Thus, the deep cooling compartment 131 is switched between the uncooled and normal freezing compartments, thereby realizing the temperature change control.
Further, the specific temperature interval of the cryogenic compartment 141 in the variable temperature mode may be adjusted by controlling the time length for which the first valve 261 conducts the refrigerant flow path in which the first refrigerant pipe 251 is located and the time length for conducting the second refrigerant pipe 252 and the refrigerant flow path in which the cryogenic evaporator 241 is located. That is, the deep cooling compartment 131 is switched between the non-cooling state and the normal freezing and cooling state, and the change of the internal temperature between the cold storage state and the freezing state can be realized. Specifically, the storage temperature in the cryogenic compartment 131 may also be adjusted by setting the preset time period to adjust the duration of the cryogenic compartment 131 in the two states of non-refrigeration and normal freezing refrigeration, respectively.
For example, when the first valve 261 has a longer time to conduct the refrigerant flow path in which the first refrigerant pipe 251 is located, and a shorter time to conduct the refrigerant flow path in which the second refrigerant pipe 252 and the cryogenic evaporator 241 are located, the cryogenic compartment 131 may be used as a cold storage compartment; when the first valve 261 has a short time to communicate with the refrigerant flow path in which the first refrigerant pipe 251 is located, and has a long time to communicate with the refrigerant flow path in which the second refrigerant pipe 252 and the cryogenic evaporator 241 are located, the cryogenic compartment 131 may be used as a temperature-changing compartment or a freezing compartment having a slightly lower temperature.
In some embodiments of the present invention, the box 10 may include an outer box 11, at least one inner container 12 disposed inside the outer box 11, and a heat insulation layer 14 disposed between the outer box 11 and the at least one inner container 12. Each inner container at least limits one storage compartment. Specifically, in the embodiment shown in fig. 1, three inner containers are defined in the box body 10, wherein one inner container is located at the upper part, and the other two inner containers are laterally arranged at the lower part side by side.
In some embodiments of the present invention, one of the storage compartments is a freezer compartment 132. The compression refrigeration system 20 further includes a freeze evaporator 242, the freeze evaporator 242 being connected in series between the first valve 261 and the freeze throttling element 232. A freeze evaporator 242 may be provided within the freezer compartment 132 or access to the freezer compartment 132 to provide refrigeration to the freezer compartment 132.
Specifically, the freezer compartment 132 may be located in a lower portion of the interior of the cabinet 10 and defined by a freezer interior.
Further, a drawer (not shown) is provided in the freezing compartment 132, and the cryogenic evaporator 241 is provided in the freezing inner container defining the freezing compartment 132 and corresponds to a region where the drawer is located to define the cryogenic compartment 131 in the drawer.
Applicants have recognized that in our daily lives, there are not many items that need to be stored deep-frozen, and therefore the space for the cryogenic compartment 131 does not need to be large. Therefore, according to the refrigerator, the drawer is arranged in the freezing chamber 132, and the cryogenic evaporator 241 is arranged in the freezing inner container corresponding to the drawer, so that the cryogenic chamber 131 is formed in the inner space of the drawer, and on one hand, the problems of complex process, high mold cost and the like caused by additionally arranging the cryogenic chamber with a smaller space on the box body structure of the traditional refrigerator are solved; on the other hand, the space size in the drawer basically meets the requirement of a user on a deep cooling space, more spaces can be uniformly distributed to be used as freezing spaces, and the reasonability of the compartment layout of the refrigerating and freezing device 1 is improved.
Applicants have recognized that the temperature within the freezer compartment 132 is relatively low and, as a result, the freezer compartment 132 is susceptible to frost or ice formation that may affect the normal push-pull operation or normal use of the drawer in the freezer compartment 132.
Therefore, the air duct structure of the refrigeration and freezing device is improved. Specifically, a plurality of induced air ports communicated with the air supply duct may be formed in the duct plate of the freezing compartment 132, and then, part of the return air in the freezing compartment 132 is introduced into the air supply duct through the induced air ports by using the jet principle, so as to be premixed with the cooling air flow with a very low temperature in the air supply duct and then sent to the freezing compartment 132. Therefore, the air flow circulation can be effectively enhanced, the temperature uniformity of the compartment is improved, and the surface of the drawer is effectively prevented from frosting or freezing.
Fig. 3 is a schematic structural view of a compression refrigeration system according to another embodiment of the present invention. In some embodiments of the present invention, one of the storage compartments is a refrigeration compartment 133. The compression refrigeration system 20 further includes a refrigeration evaporator 243 and a refrigeration throttling element 233 connected in series, the refrigeration evaporator 243 and the refrigeration throttling element 233 being connected in parallel with the freezing throttling element 232.

Specifically, the refrigerating compartment 133 may be located at an upper portion within the cabinet 10 and defined by a refrigerating inner container.
In some embodiments of the present invention, one of the storage compartments is a temperature-changing compartment 134. The compression refrigeration system 20 further includes a temperature swing evaporator 244 and a temperature swing throttling element 234 connected in series, the temperature swing evaporator 244 and the temperature swing throttling element 234 being connected in parallel with the freezing throttling element 232 and also in parallel with the series connected refrigerating evaporator 243 and the refrigerating throttling element 233. The temperature change evaporator 244 can be disposed within the temperature change compartment 134 or can be routed into the temperature change compartment 134 to provide cooling to the temperature change compartment 134. Specifically, the temperature-changing compartment 134 may be located in a lower portion of the interior of the cabinet 10 and laterally flanking the freezer compartment 132. The temperature change compartment 134 can be defined by a temperature change bladder.
Specifically, the storage temperature in the freezing chamber 132 may be-24 to-14 ℃, the storage temperature in the refrigerating chamber 133 may be 0 to 8 ℃, the storage temperature in the variable temperature chamber 134 may be-14 to 0 ℃, and the storage temperature in the deep cooling chamber 131 may cover the storage temperature intervals of the refrigerating chamber 133, the variable temperature chamber 134 and the freezing chamber 132 and further include an interval with a lower temperature. For example, the storage temperature in the deep cooling compartment 131 may be-50 to 8 ℃.
In some embodiments of the present invention, the compression refrigeration system 20 further includes a second valve 262, and the second valve 262 is used for controlling the on-off of the three refrigerant flow paths, i.e., the refrigeration evaporator 243, the refrigeration throttling element 233, the temperature-changing evaporator 244, the temperature-changing throttling element 234, and the freezing throttling element 232.

That is, the second valve 262 may be controlled to communicate only with the refrigerant flow path in which the refrigeration evaporator 243 and the refrigeration throttling element 233 are located, may be controlled to communicate only with the refrigerant flow path in which the temperature-varying evaporator 244 and the temperature-varying throttling element 234 are located, or may be controlled to communicate only with the refrigerant flow path in which the freezing throttling element 232 is located.
