Below with reference to accompanying drawing, describe in detail according to the hold-over plate 100 for refrigerator of the embodiment of the present invention.
As shown in Figure 1-2, the hold-over plate 100 for refrigerator according to the embodiment of the present invention, comprising: housing 10 and a plurality of cold-storages unit 20.
Particularly, in each cold-storage unit 20, be packaged with phase change cold accumulating agent (scheming not shown).Be understandable that, the shape of cold-storage unit 20 is not done to particular restriction, for example, in one embodiment of the invention, cold-storage unit 20 can be hollow ball, and covert agent for storage of coldness is located in spheroid.Cold-storage unit 20 can be located in housing 10.It should be noted that, take liquid-solid phase change cold accumulating agent as example, when phase change cold accumulating agent is cooled to solidification temperature, just produce from liquid state to solid-state phase transformation, in cooling process, phase-change material absorbs and stores a large amount of colds; When phase-change material melts, the cold of storage goes will be dispersed into environment in certain temperature range in, carries out the reverse transformation from solid-state to liquid.
When refrigerator is started shooting operation for the first time, between refrigeration, indoor temperature is normal temperature, and now phase change cold accumulating agent state is solid-state.When compressor operating is after a period of time, between refrigeration, indoor temperature is reduced to transformation temperature upper (being for example 5 ℃), and now phase change cold accumulating agent starts by liquid state to solid-state conversion, and carries out cold-storage.Also it should be noted that, when the shutdown temperature of design compressor, the target temperature of shutdown can be suitably lower than phase point temperature; that is to say, phase change cold accumulating agent be converted into completely solid-state after, compressor continues operation; until indoor temperature is lower than phase point temperature between refrigeration, compressor is out of service.Thus, extend compressor operating time, reduced the start-stop rate of compressor, thereby reached energy-conservation object.
After once compressor is out of service, indoor temperature bottom out between refrigeration, when indoor temperature is elevated to transformation temperature, phase change cold accumulating agent starts to occur solid-state to liquid reverse transformation, and the cold storing is before discharged, this will make between refrigeration indoor temperature constant in transformation temperature, and between namely freezing, the temperature of chamber will keep a period of time at phase point temperature, until agent for storage of coldness is converted into liquid state completely, till stored cold discharges totally before.After this, between refrigeration, indoor temperature continues to rise, until reach compressor start target temperature, compressor starts refrigeration again, and so forth.Thus, extend the downtime of compressor, reduced the start-stop rate of compressor, thereby reached energy-conservation object.In addition, phase change cold accumulating agent has extended the time that between refrigeration, indoor temperature declines and gos up, and has reduced fluctuations in indoor temperature between refrigeration, thereby has improved the fresh-keeping effect of food.
According to the hold-over plate 100 for refrigerator of the embodiment of the present invention, by the indoor hold-over plate 100 that arranges between refrigeration, when compressor operating, cold-storage unit 20 is stored in cold in covert agent for storage of coldness, to extend the running time of compressor; When compressor is out of service, cold-storage unit 20 released cold quantities, to extend the downtime of compressor.Thus, by extending operation and the downtime of compressor, reduced the number of starts and the start-stop rate of compressor, thereby reached energy-conservation object.In addition, phase change cold accumulating agent has extended the time that between refrigeration, indoor temperature declines and gos up, and has reduced fluctuations in indoor temperature between refrigeration, thereby has improved the fresh-keeping effect of food.
As shown in Figure 1, according to one embodiment of present invention, housing 10 can be cuboid, is provided with the cold-storage unit 20 of one deck setting adjacent one another are in housing 10.Be understandable that, the number of plies of the interior cold-storage of housing 10 unit 20 is not limited to this, for example, as shown in Figure 2, in another specific embodiment of the present invention, is provided with the cold-storage unit 20 of multilayer setting adjacent one another are in housing 10.In addition, the shape of housing 10 is also not limited to cuboid, and according to one embodiment of present invention, housing 10 is " C " shape, and in " C " shape housing (scheming not shown), is provided with the cold-storage unit 20 of at least one deck setting adjacent one another are.
For the phase change cold accumulating agent that between refrigeration, chamber is selected, the selection of best transformation temperature should be the optimum temperature point according to food fresh keeping, by phase change cold accumulating agent, extends the time of food in this temperature spot, and then produces best fresh-keeping effect.For example, according to one embodiment of present invention, in cold-storage unit 20, be packaged with transformation temperature and be the agent for storage of coldness of 3-6 ℃.Preferably, in cold-storage unit 20, being packaged with transformation temperature is the agent for storage of coldness of 5 ℃.
According to the refrigerator of the embodiment of the present invention (scheming not shown), comprising: casing, door body and hold-over plate 100.Particularly, casing has chamber between refrigeration.Men Tiyu casing connects, to open or close chamber between refrigeration.Hold-over plate 100 is located between refrigeration indoor.
According to the refrigerator of the embodiment of the present invention, by the indoor hold-over plate 100 that arranges between refrigeration, when compressor operating, cold-storage unit 20 is stored in cold in covert agent for storage of coldness, to extend the running time of compressor; When compressor is out of service, cold-storage unit 20 released cold quantities, to extend the downtime of compressor.Thus, by extending operation and the downtime of compressor, reduced the number of starts and the start-stop rate of compressor, thereby reached energy-conservation object.In addition, phase change cold accumulating agent has extended the time that between refrigeration, indoor temperature declines and gos up, and has reduced fluctuations in indoor temperature between refrigeration, thereby has improved the fresh-keeping effect of food.
According to an example of the present invention, hold-over plate 100 can be located on the roof of chamber between refrigeration.When hold-over plate 100 released cold quantity, cold air can from top to bottom flow.Thus, delay the time that between refrigeration, indoor temperature is gone up, reduced indoor temperature fluctuation between refrigeration.Certainly, the placement location of hold-over plate 100 is not limited to this, and in another example of the present invention, hold-over plate 100 can also be located on the sidewall of chamber between refrigeration.
