Abstract
The invention discloses a refrigerator achieving intelligent heat pipe unfreezing and relates to the field of household appliances. According to an existing household refrigerator, the taste is affected and nutrition is lost due to rapid unfreezing of food, and manual operation is needed when food is unfrozen in refrigerating chambers. The refrigerator achieving intelligent heat pipe unfreezing achieves unfreezing in a preset mode by the utilization of a single-chip microcomputer control technology and a controlled heat pipe technology. The refrigerator achieving intelligent heat pipe unfreezing comprises a plurality of heat insulating freezing chambers the refrigerating chambers, the temperature of the freezing chambers and the temperature of the refrigerating chambers are controlled independently, the refrigerating chambers and the freezing chambers are connected through heat pipes, the heat pipes are provided with solenoid valves, and a single-chip microcomputer system controls the solenoid valves to operate or stop. When the heat pipes operate, heat transfer media in the heat pipes flow to the freezing chambers slowly by carrying heat of the refrigerating chambers, frozen food is unfrozen slowly within the time preset by a user, the amount of lost juice is reduced when the frozen food is unfrozen, and the nutrition and taste of food are reserved. Meanwhile, as the multiple independent heat insulating freezing chambers are provided and cold of the freezing chambers flows to the refrigerating chambers slowly, compared with the existing refrigerator, the refrigerator achieving intelligent heat pipe unfreezing can save more electric energy.
Description
Technical field
The present invention relates to refrigeration technology field, relate in particular to domestic refrigerator.
Background technology
The frozen food temperature variation curve of existing main flow refrigerator as shown in Figure 2,1 stage, cooling frozen food; In 2 stages, food is in freezing preservation; In 3 stages, food is taken out in refrigerator, is placed on the plate that thaws and naturally thaws; In 4 stages, heating is thawed, and user is not free to be waited nature and thaw, and just puts into warm water or micro-wave oven thaws.On dining table, the meat product of quick-thawing is as the mouthfeel of blockishness, and part is remained on dining table, finally abandons.
Experienced user, proceeds to refrigerating chamber from refrigerating chamber in advance by freezing food, and as shown in Figure 3, in 1 stage, food cooling is freezing for its variations in temperature; In 2 stages, food is in freezing preservation; In 3 stages, food slowly thaws at refrigerating chamber; In 4 stages, food is taken out in refrigerator, and food is placed under normal temperature environment and cooks, and on dining table, nutrition is good to eat is favourably welcome.But the present people who does not generally have enough sleep, often forgot frozen food is proceeded to refrigerating chamber from refrigerating chamber in busy morning.When culinary art, only have again quick-thawing, because mouthfeel is too poor, part is outwelled.The inconvenience of thawing, user abandons using refrigerating chamber or the full busy culinary art of thawing of refrigerating chamber.
Inside heat pipe mainly leans on the liquid and vapor capacity phase-change heat transfer of heat transfer medium, thermal resistance is very little, therefore there is the very high capacity of heat transmission, compared with silver, copper, aluminium .., the heat pipe of Unit Weight can transmit the heat of several orders of magnitude more, there is the invertibity of good isothermal, heat flow density changeability and direction of heat flow, certainly, high-termal conductivity is also comparatively speaking, the second law of thermodynamics shows what the temperature difference always existed, heat pipe is mainly used in heat radiation and the samming of electronic device at present, seldom applies at family expenses refrigeration technology field.
Document " thawing apparatus and be provided with the refrigerator of thawing apparatus " CN102878756A, discloses a kind of thawing apparatus, uses hot pipe technique to thaw.CN02121055.1 proposes to adopt the used heat of Machine Room to thaw; The thawing apparatus that CN97126440.6 proposes, this thawing apparatus not only needs electric heater and air-supply arrangement, also will have independent space.Therefore, provide a kind of and can reduce the infringement of course of defrosting to food mouthfeel and nutrition and the refrigerator automatically thawing becomes the industry technical issues that need to address.
Summary of the invention

dfood, in frozen state, has thawed.In heat pipe intelligence refrigerator capable of defrosting experimental system, the temperature variation curve of frozen food as shown in Figure 4.
The beef experiment of thawing, Sunday, 8 users put into beef in refrigerating chamber 102, input take-off time by keyboard, estimate 17 of Tuesday and take out cooking food, refrigerating chamber refrigeration, order Sunday 20 and reach minimum cryogenic temperature, 23 complete refrigerating chamber nature thawing time and the test of refrigerating chamber heat pipe thawing time, heat pipe thawing time is 12 hours, nature thawing time is 24 hours, close refrigerating chamber 102 refrigerant tubings on 23 of Mondaies and connect the valve of compressors, refrigerating chamber 102 enters nature heat absorption thawed state, it is-7.2 DEG C to 11 temperature rises on Tuesday, refrigerating chamber 102 enters heat pipe thawed state, Tuesday 17 point, the temperature of refrigerating chamber 102 is 1.8 DEG C.
In sum, the present invention has following beneficial effect.
1. the taste of defrosting food and nutrition reservation are better than prior art.As shown in Figure 9, from the relatively impact of course of defrosting on beef in appearance, the raw beef of Fig. 9-B, the structure of meat fiber completes, and meat fiber is arranged closely, muscle fibre spacing minimum.Fig. 9-C puts into the beef that warm water thaws 25 minutes after being placed on and thawing 25 minutes on the plate that thaws again, and in course of defrosting, meat fiber protein oxidation and skelemin degraded have destroyed musculature.The structural intergrity of freezing beef meat fiber suffers that, compared with heavy damage, exomysium breaks more, and their muscle fibre spacing is larger.Fig. 9-A is that heat pipe intelligence is separated chilled beef, and compared with thawing with the plate that thaws, the beef myocytolysis degree that intelligence is thawed is less less with their muscle fibre spacing, and exomysium is more complete.Nutritive loss correction data is as shown in table 1, and group 1 is the intelligence experiment group of thawing, and group 2 is the plate control groups that thaw that thaw.Compared with the plate solution chilled beef that thaws, the heat pipe intelligence beef juice loss that thaws has reduced by 4.05%, and protein loss reduces 0.85%, and intelligence is thawed and significantly reduced juice loss, protein loss.In a word, heat pipe intelligence is thawed and has been retained better taste and the nutrition of frozen food.
Table 1 nutritive loss contrast table
。
2. saved electric power.One, refrigerating chamber is divided into multiple, and each access food is only opened corresponding refrigerating chamber, and cooling gas leakage amount only has original part.Its two, the cold of refrigerating chamber is transmitted to refrigerating chamber, the cold of course of defrosting is recycled.
3. comprehensively measuring and calculating, purchasing price improves, and use cost declines, and totle drilling cost slightly declines, and the user who is applicable to all levels of consumption uses.Heat pipe intelligence refrigerator capable of defrosting improves the quality of frozen food under the condition that does not increase totle drilling cost, ensures kinsfolk's health of user.
In a word; although the present invention has enumerated above-mentioned preferred embodiment, should illustrate, although those skilled in the art can carry out various variations and remodeling; unless such variation and remodeling have departed from scope of the present invention, otherwise all should be included in protection scope of the present invention.
