Abstract
The invention discloses an energy-saving refrigerator and belongs to the technical field of refrigerator energy conservation. Before polyurethane foam is filled in a heat-insulating layer to foam, one or two high-vacuum thermal insulation plates are arranged in the heat-insulating layer. The whole heat-insulating material consists of polyurethane open-cell foam, an air adsorbent and a trapping membrane, wherein the polyurethane open-cell foam serves as a core heat-insulating material; the aperture ratio of the polyurethane foam is more than or equal to 95 percent; and the polyurethane open-cell foam is vacuumized and is sealed by the trapping membrane, so that the heat conductivity is greatly reduced. A double-magnetic stripe door seal is arranged at a connecting place of the cabinet body and a door body; two parallel magnetic stripes of which the length is 4 to 6mm respectively pass through two correspondingly independent air bags; and a small air bag is spaced between the two air bags. The two magnetic stripes realize two door seals and have complementary effect of two sealing surfaces which overcome leakage caused by warping of a single magnetic stripe and guarantee that the seal is more thorough. The aim of energy conservation and consumption reduction is fulfilled by changing the material and structure of the heat-insulating layer and the mounting positions and number of the magnetic stripes of the door seal.
Description
Technical field
The present invention relates to a kind of refrigerator, more particularly, is a kind of energy-saving-type cold storage household freezer.
Background technology
The appearance of refrigerator has only short decades, update but experienced several times, the external form volume develops into multi-door big capacity by the simple gate low capacity, function and usage is by the single freezing how warm multi-layer multi purposes that develops into, control mode is developed into digital control by mechanical type, but increase the volume and the capacity of refrigerator, mean and to take bigger space, expend the more energy, this must be subjected to the restriction of living conditions and energy scarcity, many other purposes of refrigerator are additional function, and freezing and refrigeration is the basic function of refrigerator forever, and hommization, energy-conservationization and high efficiency are the themes of refrigerator development.
The power-saving technology of present domestic refrigerator mainly contains the energy consumption that reduces refrigerator from following several aspects: 1) increase the refrigerator depth of foam, common refrigerator refrigerating chamber depth of foam is 35mm to 45mm, refrigerating chamber Baidu is 60mm to 80mm, in order to reduce the radiation of cold to the external world, the depth of foam of refrigerating chamber is increased to 55mm to 65mm, the refrigerating chamber depth of foam increases to 85mm to 100mm even 120mm, and increases the cost that depth of foam will certainly increase refrigerator; 2) adopt mechanical temperature controller, the freezer compressor start-stop of single round-robin system cooling system is controlled by temperature of refrigerating chamber only, compares the refrigerator of cycle refrigeration system mutually, and the available machine time is short, comparatively power saving; 3) adopting high-efficient compressor, is the main means of present refrigerator energy-saving; 4) adopt the gasbag-type gasket, whether refrigerator doors fastens, this can directly influence the operating efficiency of refrigerator, thereby refrigerator gas leakage can cause the refrigeration variation to increase power consumption, also cause compressor to start repeatedly easily and burn, adopt gasket can reduce cold and flow out, increase power consumption by the refrigerator doors slit.
The conventional power-saving technology of above-mentioned refrigerator, have simple, the reliability advantages of higher of production technology, but shortcoming is also comparatively obvious: blocked up foaming can influence the attractive in appearance of refrigerator, and increases the production cost of refrigerator; There are problems such as operation is inconvenient, the freezing ability of single loop system is relatively poor in mechanical temperature controller; The high-efficient compressor construction cycle is long, and can improve the cost of refrigerator integral body; Adopt gasket, most of refrigerator adopts a whole magnetic stripe to come the adhesive outcase of refrigerator to seal, in case cabinet shell out-of-flatness or impurity is arranged, will cause whole adhesive face " warping ", thereby cause a body joint to produce the slit, cause the interior cold air of refrigerator excessive, the heat-insulating property variation, power consumption rises.
For this reason, now many refrigerator products adopt vacuum heat-insulating plate to improve effect of heat insulation, application mode normally is pasted on it outcase of refrigerator inboard or inner chamber outside, paste normal higher double faced adhesive tape or the thermosol of price that adopt and be coated on evacuated panel and adhesive surface, but this mode cost is higher, and in actual applications, because outcase of refrigerator, inner chamber outer surface injustice, usually cause vacuum heat-insulating plate and outcase of refrigerator, inner chamber can not 100% contact fully, after foaming, produce from bubble or cavity phenomenon, frothing percentage is not high, has limited the application of vacuum heat-insulating plate on refrigerator.
Summary of the invention
In order to solve deficiency of the prior art, the invention provides a kind of energy-saving-type cold storage household freezer, by changing refrigerator structure and adopting new material, do not adopting expensive, high-efficient compressor and do not increasing under the prerequisite of depth of foam, effectively reduce the thermal conductivity of refrigerator, reduce the energy consumption of refrigerator, reach purpose energy-conservation, consumption reduction.
The objective of the invention is to realize by following technical scheme:
