Description
[technical field]
The utility model is about a kind of refrigerating plant, particularly about a kind of refrigerating plant with defrost function.
[background technology]
Existing refrigerator has Defrost heater, and this heater is configured to the frost that thaws and do not expected.Most technological improvement all is at the frost of how effectively removing on the evaporimeter.A kind of like this refrigerator is arranged, and evaporimeter is the outside that is surrounded on inner container of icebox, and is fixing by the blowing agent foaming.Because the moisture in the evaporimeter discord refrigerator directly contacts, and therefore, does not have frost on the evaporimeter, frost is formed on the inner bag of refrigerator, especially evaporimeter around the inner bag part, the frosting phenomenon is comparatively general.
In order to address the above problem, prior art is taked two kinds of schemes: the one, and direct fixing heater strip on evaporator pipeline; The 2nd, in a side of evaporimeter the thermal treatment zone is set, the formed cooling zone of the thermal treatment zone and evaporimeter is separately.All there is at least one shortcoming in above-mentioned two kinds of schemes, heater strip in first kind of scheme is fixed on the evaporator pipeline, refrigerant temperature ascensional range in heating process makes evaporator pipeline and pipeline is bigger, in the cold-producing medium cyclic process, strengthen the load of compressor, the shortcoming of second kind of scheme is that the heat that heater sends can't evenly distribute, if will reach the effect of defrosting fully, promptly make and come off apart from the thawing of the frost on the heater locations inner bag far away, then need the long time of heater work, during this period, no matter whether refrigerating function continues, and all can influence the effect of refrigerator refrigeration.

Structure of the present utility model and its other utility model purposes and beneficial effect will be in conjunction with the drawings and description of preferred embodiments and becoming apparent more.
[description of drawings]
The part of book and in order to providing as an illustration to further understanding of the present utility model, the following drawings diagram specific embodiment of the present utility model, and be used for illustrating principle of the present utility model with specification.Wherein,
Fig. 1 is the cutaway view of storeroom of the present utility model.
Fig. 2 is the enlarged drawing of the local A of Fig. 1.
[specific embodiment]
To be described in detail exemplary embodiments of the present utility model now, its example is shown in the drawings, and identical Reference numeral is represented identical original paper in all accompanying drawings.Below will embodiment be described with explanation the utility model by reference accompanying drawing 1 and Fig. 2.
The utility model provides a kind of refrigerating appliance, for example a kind of refrigerator, this refrigerating appliance has a material storage room 22 at least, the profile of refrigerating appliance is limited by the shell (not shown), the shape of material storage room 22 is limited by the inner casing 20 that is positioned in the shell, and the filled with foaming material (not shown) is in order to thermal insulation between shell and the inner casing 20.This inner casing 20 has the rear wall 14 of the relative inner casing 20 of an opening 12 that is used to take or puts into food and opening 12 and inner casing 20 walls around all the other.
Be provided with evaporation tube 16 on the outer wall 21 of inner casing 20, evaporation tube 16 is directly used in cooling material storage room 22 as the part of refrigerating circuit in the refrigerating appliance, and this refrigeration modes is called as " direct-cooled ".For the efficient that increases refrigerated area and improve refrigeration, evaporation tube 16 is arranged on the outer wall 21 of inner casing 20 in the mode of twining.
Present embodiment adopts the mode to the heating wire heating to defrost, and for area that increases the heating region covering and the efficient that improves defrosting, the set-up mode of heater strip 15 and evaporation tube 16 are similar, promptly are arranged on the outer wall 21 of inner casing 20 in the mode of twining.
In order to defrost rapidly, shorten the time of heater strip operation, heater strip 15 is configured to parallel mutually with evaporation tube 16, promptly one section heater strip 15 correspondence that parallel with it and one section evaporation tube 16 equal length, the frost that is produced by evaporation tube cold storage chambers 16, especially near evaporation tube 16 cooled zones, too near heater strip 15 area heated, therefore, after frost forms, give heater strip 15 heating, the temperature between the inwall 13 of can raise rapidly frost and inner casing 20, thus make frost drop from the inwall 13 of inner casing 20.The operation of 15 short time of heater strip can make to greatest extent that the temperature in the storeroom can obviously not raise, thereby keep low temperature environment, alleviates the burden of refrigerating circuit.
Though heater strip 15 is mutually parallel with evaporation tube 16, but do not link to each other each other, reduce heater strip 15 influence to evaporation tube 16 in the process of heating, as far as possible after defrost is finished, the temperature of the cold-producing medium in evaporation tube 16 and the pipe can obviously not raise, and alleviates the burden of compressor.
In order to make cold air and heat that evaporation tube 16 and heater strip 15 are produced spread to uniformly in the material storage room 22, on the whole outer wall 21 of inner casing 20, heat-conducting layer 11 is set, promptly between the outer wall 21 of evaporation tube 16, heater strip 15 and inner casing 20, wherein evaporation tube 16, described heater strip 15 all contact with heat-conducting layer 11 this heat-conducting layer 11.Preferred a kind of embodiment, the material of heat-conducting layer 11 uses aluminium foil, because the aluminium foil good heat conductivity, and cost is low.
Two sides at aluminium foil layer 11 is equipped with glue, and the glue of one side makes aluminium foil layer 11 be fixed on the outer wall 21 of inner casing 20, and the glue of another side is used for fixing heater strip 15 and evaporation tube 16.In process, heater strip 15 can paste aluminium foil layer 11 in advance, and aluminium foil layer 11 and heater strip 15 are fixed to the outer wall 21 of inner casing 20 together then, has reduced the time of installing, and has improved existence efficient.
Because evaporation tube 16 has the quality that manys that weighs than heater strip 15, therefore,, between evaporation tube 16 and aluminium foil layer 11, use 17 pairs of evaporation tubes 16 of solid gum to fix for more firm fixedly evaporation tube 16.Twine in the process of inner casings 20 at evaporation tube 16 and heat-conducting layer 11, evaporation tube 16 all forms the turn of bilge that conforms to inner casing 20 shapes with heater strip 15, and turn of bilge bends on the outer wall 21 that is close to inner casing 20, helps improving the effect of freezing and defrosting.
In the present embodiment, evaporation tube 16 and heater strip 15 are on all the other walls that are wrapped in uniformly except that the rear wall of inner casing 20, uniform winding is in order to make cold air or heat distribute more uniformly on inner casing 20, is convenient to installation and be wrapped on all the other walls except that the rear wall 14 of inner casing 20.Certainly, in another embodiment, evaporation tube 16 and heater strip 15 also can be wrapped on all outer walls 21 of inner casing 20.
