Abstract
The utility model discloses an energy-saving refrigerator which comprises an inner shell and layers of inner cavity evaporators. The inner cavity evaporators are arranged in a cavity chamber of the inner shell. An outer cavity evaporator is arranged on the peripheral surface at the outer part of the inner shell. The energy-saving refrigerator adopts the design that the outer cavity evaporator is arranged on the peripheral surface at the outer part of the inner shell; therefore, when the refrigerator is started, the inner cavity evaporators in the cavity chamber of the inner shell and the outercavity evaporator at the outer part of the inner shell form a three-dimensional cold air curtain, and the refrigeration is quicker and more powerful; when the refrigerator is stopped, the temperatureof the outer cavity evaporator is less than 30 DEG C below zero and is far lower than the indoor load temperature, and heat transmitted through a heat isolating layer can be absorbed. The design of the energy-saving refrigerator meanwhile meets the requirements of temperature reduction and heat preservation, the refrigerator is more energy-saving, the indoor temperature is uniform, and the refrigerator is beneficial for keeping food fresh; moreover, the design structure of the refrigerator is simple, the technique operation is quite simple as well as convenient, and the cost is low.
Description
Technical field
The utility model relates to a kind of freezing equipment, particularly a kind of energy-saving electric refrigerator.
Background technology
Current, many resources are all more in short supply, and electric energy also is so, so the energy-conservation development trend that has become the refrigerator industry of refrigerator.Mainly can design than the energy-conservation of refrigerator from two aspects.The first, the cooling rate of indoor load when starting to improve refrigerator with the increasing disengagement area by the temperature that improves evaporimeter.Way is more effectively, improves compressor COP value, or the evaporimeter in the refrigerating chamber is optimized.As evaporimeter is encrypted, on evaporation tube, increase radiating fin etc.The second, load rise speed as the thermal insulation layer of thickening casing, adopts vaccum thermal insulation technique etc. when reducing the refrigerator shutdown.Therefore, make refrigerator have a good energy-saving effect to improve evaporimeter in thermal insulation layer, the refrigerating chamber or compressor simultaneously, not only cause the waste of material resources, and technological operation complexity, the production cost height costs an arm and a leg, and can not satisfy whole people's requirements of saving energy.
The utility model content
In order to overcome the deficiencies in the prior art, the utility model provides the refrigerator that a kind of cost is lower, energy-conservation, technological operation is easy.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of energy-saving electric refrigerator comprises inner casing and is arranged on the interior several layers inner chamber evaporimeter of inner casing chamber that the surrounded surface of described inner casing outside is provided with the exocoel evaporimeter.
As further improvement of the utility model, described exocoel evaporimeter comprises evaporation tube and heat transfer plate, and described heat transfer plate places between evaporation tube and the inner casing.
As another kind of improvement the of the present utility model, described exocoel evaporimeter comprises evaporation tube and aluminium foil, and described aluminium foil covers on the surface of evaporation tube and inner casing.
The beneficial effects of the utility model are: because the surrounded surface of the utility model inner casing outside is installed the exocoel evaporimeter, after the refrigerator start, the inner chamber evaporimeter in the inner casing chamber and the exocoel evaporimeter of inner casing outside have formed three-dimensional cold air curtain, greatly very high disengagement area, cold air is alternately transmitted, and it is rapider powerful to freeze; Simultaneously because the effect of exocoel evaporimeter, when refrigerator is shut down, can avoid the interior load temperature of temperatures involved case of external environment to go up, the high temperature that more helps stoping the radiator arranged on the refrigerator left side plate to bring, when refrigerator is started shooting refrigeration once more, cold-producing medium is very fast takes away the external heat that absorbs on the exocoel evaporimeter, so appropriate design startup-shutdown time scale can reach desirable heat insulation effect; The design has satisfied the requirement of cooling and insulation simultaneously, and refrigerator is more energy-conservation, and indoor temperature is even, helps food fresh keeping, and the design is simple in structure simultaneously, and technological operation is also very easy, and cost is lower.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the first embodiment stereogram of the present utility model;
Fig. 2 is the second embodiment stereogram of the present utility model;
Fig. 3 is a fundamental diagram of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of energy-saving electric refrigerator comprises inner casing 1 and is arranged on the interior several layers inner chamber evaporimeter 2 of inner casing 1 chamber that the surrounded surface of described inner casing 1 outside is provided with exocoel evaporimeter 3.By compressor 5, condenser 6, filter 7, capillary 8, inner chamber evaporimeter 2, exocoel evaporimeter 3, refrigerator evaporator 4 constitute the single round-robin system cooling system simultaneously.When refrigerator start refrigeration, the cold-producing medium that comes out from capillary 8 at first passes through inner chamber evaporimeter 2, because inner chamber evaporimeter 2 directly contacts with load, refrigerating speed is fast, and cold-producing medium passes through exocoel evaporimeter 3 more then, inner chamber evaporimeter 2 in inner casing 1 chamber is equivalent to form three-dimensional cold air curtain with the exocoel evaporimeter 3 of inner casing outside, greatly very high disengagement area is alternately transmitted cold air, and it is rapider powerful to freeze, temperature in inner casing 1 chamber is also more even, helps food fresh keeping; When refrigerator is shut down, heat transfer plate 32 temperature are below-30 ℃, inner casing 1 chamber internal burden temperature remains on-18 ℃, it is lower 12 ℃ than food temperature at least to be equivalent to heat transfer plate 32 temperature, can avoid the interior load temperature of temperatures involved case of external environment to go up, the high temperature that more helps stoping the radiator arranged on the refrigerator left side plate to bring, when refrigerator start next time refrigeration, cold-producing medium is very fast takes away the external heat that absorbs on the heat transfer plate in the exocoel evaporimeter 3 32, therefore appropriate design startup-shutdown time scale, the temperature recovery of the heat transfer plate when being about to shut down in the evaporimeter of refrigerating chamber surrounded surface to time of-18 ℃ as downtime length can reach desirable heat insulation effect; The design is simple in structure simultaneously, and technological operation is also very easy, and cost is lower, can satisfy whole people's requirements of saving energy.
Described exocoel evaporimeter 3 comprises evaporation tube 31 and heat transfer plate 32, and heat transfer plate 32 places between evaporation tube 31 and the inner casing 1, and heat transfer plate 32 can fully contact with housing 1, helps refrigeration; This exocoel evaporimeter 3 also can adopt alternate manner in addition, and promptly exocoel evaporimeter 3 comprises evaporation tube 31 and aluminium foil 33, and evaporation tube 31 is on housing 1, and aluminium foil 33 covers the surface of evaporation tube 31 and housing 1, can freeze effectively.
Certainly, the utility model is created and is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
