Refrigerator stores and fresh-keeping device as popular home food, has become the article that each family is indispensable.China is as Small Refrigerating Equipment production and consumption big countries such as refrigerators, and refrigerator total output in 2012 is 6,600 ten thousand according to statistics, and the domestic refrigerator total market sales is 41,000,000.Total recoverable amount of current China refrigerator has broken through 2.5 hundred million, close to 300,000,000.
Refrigerator traditional mostly in the market is two Room or three compartment refrigerators, and the refrigeration system pipeline of refrigerator comprises compressor, condenser pipe, dew eliminating tube, device for drying and filtering, capillary, freezing and evaporating pipeline, refrigeration evaporation pipeline, reservoir.Wherein, compressor and reservoir are positioned at bottom refrigerator, and condenser pipe is positioned at refrigerator body both sides or rear portion, and dew eliminating tube is positioned at refrigerating chamber door seal place, and freezing and evaporating pipeline is positioned at refrigerating chamber, and refrigeration evaporation pipeline is positioned at refrigerating chamber.In whole refrigeration system pipeline, dew eliminating tube and condenser pipe have thermolysis, and evaporation pipeline has refrigeration.
Conventional household refrigerator only utilizes the refrigeration of refrigeration system, and fresh-keeping to the material object cooling in freezing or refrigerating chamber, the effect that heats for refrigeration system utilizes less, is only used in the anti-dew of refrigerating chamber door seal.
Summary of the invention
For the problems referred to above, main contents of the present invention are to provide a kind of novel accumulation of heat for domestic refrigerator and thaw heat-insulation system.This system increases an accumulation of heat defrosting room in conventional refrigerator.Accumulation of heat defrosting room is positioned at refrigerator top, and outward appearance and refrigerator are integral type structure, heat insulation with other case rooms.In accumulation of heat defrosting room, increase accumulation of heat coil pipe, outside pipeline, have phase change heat storage material.Wherein, accumulation of heat coil pipe belongs to refrigeration system pipeline, from introducing accumulation of heat defrosting room between dew eliminating tube and condenser pipe.Phase change heat storage material wherein outside pipeline is the mixture of paraffin and butyl stearate.
Adopt the phase transformation defrosting room of accumulation of heat coil pipe and phase change heat storage material, the condensation heat of refrigerator can be stored with the form of latent heat of phase change, when needing food defrosting or insulation, even if freezer compressor does not work, time accumulation of heat coil pipe does not have heat to produce, phase change heat storage material also can provide enough heats.
For achieving the above object, the present invention adopts following technical scheme:
On the basis of traditional domestic refrigerator, increase an accumulation of heat defrosting room, by refrigerator refrigerant circulation line, the pipeline access accumulation of heat defrosting room between dew eliminating tube and condenser pipe, as accumulation of heat coil pipe, each several part relation is as follows:

The order of connection of described accumulation of heat coil pipe is:
Described accumulation of heat coil pipe accesses accumulation of heat defrosting room between the dew eliminating tube and condenser pipe of refrigeration system; After high temperature refrigerant flows through dew eliminating tube, enter accumulation of heat coil pipe, at accumulation of heat defrosting room heat releaseafter, leave accumulation of heat coil pipe, enter condenser pipe.
The structure of described accumulation of heat defrosting room is:
accumulation of heatdefrosting room is cuboid box room, is divided into two-layer up and down; Lower floor is regenerator, and accumulation of heat coil pipe is positioned at lower floor, and accumulation of heat coil pipe is externally connected with radiating wire, for enhanced heat exchange, is placed horizontally in the middle part of described regenerator; Fill phase change heat storage material in regenerator, phase change heat storage material is the mixture of paraffin and butyl stearate, and its ratio is 1:1 ;dividing plate between levels is metal guide hot plate; Upper strata is defrosting room, for placing food.
The thaw course of work of heat-insulation system of the described accumulation of heat for domestic refrigerator is as follows:
First the heat-accumulating process of accumulation of heat defrosting room is carried out.When freezer compressor works, cold-producing medium flows out from compressor, for high-temperature gas, through dew eliminating tube, shed partial heat, prevents refrigerating chamber door sealed knot from revealing, rear inflow accumulation of heat coil pipe, in accumulation of heat coil pipe, cold-producing medium and phase change heat storage material heat exchange, make material melts, and to top defrosting room heat release, defrosting room and heat-storing material are heated up, renews heat, the cold-producing medium after heat exchange enters the abundant heat release of condenser pipe, by throttling, produce refrigeration at freezing and refrigerating chamber, get back to compressor again by reservoir, complete kind of refrigeration cycle ;in compressor operating process, heat-storing material constantly absorbs heat thawing, carries out heat-accumulating process.
When after compressor shutdown, heat-accumulating process terminates.Accumulation of heat defrosting room enters insulating process.Its internal temperature maintains higher temperature levels.
When needs thaw to food, when maybe will preserve heat food, food is put into accumulation of heat storeroom, process of starting working.Phase change heat storage material stores a large amount of latent heat of phase change, and during defrosting food, the temperature difference is comparatively large, and heat-storing material completes phase transformation exothermic process fast, discharges amount of heat rapidly, quick-thawing food.During to the insulation of heat food, have a narrow range of temperature, phase-change material slow releasing latent heat of phase change, can be incubated the long period.
After the course of work, after accumulation of heat defrosting room needs again to experience heat-accumulating process, could task again.
The accumulation of heat for domestic refrigerator in the patent of the present invention heat-insulation system that thaws has following function:
1, quick-thawing food; 2, insulation or heated food.
The accumulation of heat for domestic refrigerator of the Patent design of the present invention heat-insulation system tool that thaws has the following advantages:
1, limited repacking is carried out to conventional refrigerator, reach the object that this patent accumulation of heat is thawed, be easier to technically realize.
The thermal source of the accumulation of heat defrosting room of the refrigerator 2, in this patent, from the condensation heat of refrigerator, belongs to Waste Heat Recovery and utilizes, have the effect of energy-saving and emission-reduction.
3, the heat-storing material in this patent in accumulation of heat defrosting room is phase change heat storage material, is compared to traditional water accumulation of heat, can stores more heat, can maintain the temperature of accumulation of heat defrosting room for a long time in higher level.
