Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, the utility model embodiment defrosting system of refrigerator comprise vaporizer body 1 and be arranged on bottom vaporizer body 1 for the precooling evaporator 2 cooled the hot and humid air of returning from return air inlet and dehumidify, described precooling evaporator 2 one end is connected with return air inlet, and one end is connected with vaporizer body 1.The wind cooling refrigerator of defrosting system of refrigerator, after the hot and humid air of returning from return air inlet is undertaken cooling and dehumidify by precooling evaporator 2, again by vaporizer body 1 cooling heat transferring, part frost is made to condense on precooling evaporator 2 like this, thus the frosting degree in vaporizer body 1 obviously reduces, and frosting is even, effectively raises the heat exchange efficiency of vaporizer body.Preferably, before and after described precooling evaporator 2, at least side of both sides is provided with defrosting heater 3 bottom at least one, and described bottom defrosting heater 3 is positioned at the lower end of described vaporizer body 1.Because the frost layer on precooling evaporator 2 is thicker, be close to precooling evaporator 2, arrange a bottom defrosting heater 3, bottom this, defrosting heater 3 fully can heat precooling evaporator 2, therefore can reach the effect of precooling evaporator 2 being carried out to highly effective defrosting.And described bottom defrosting heater 3 also can heat from bottom to vaporizer body 1, eliminates the frost of vaporizer body 1 bottom.As further preferred version, only a bottom defrosting heater 3 is set in the front side of the bottom of vaporizer body 1 and described precooling evaporator 2.Described bottom defrosting heater 3 can comprise one deck heating tube.But be not limited thereto, also can be made up of two-layer or Multi-layer warming pipe.Although the heat of single bottom defrosting heater 3 can up conduct, and then part defrost is carried out to vaporizer body 1, but its heat is more and more weak from bottom to top, therefore can not ensure that the frost of vaporizer body 1 can fully be changed only, and cause defrost overlong time, also easily cause food temperature to go up while waste electric energy higher.Therefore at least side of the both sides, front and back of described vaporizer body 1 is provided with at least one upper end defrosting heater 4.Adopt upper end defrosting heater 4 pairs of vaporizer body 1 to carry out heating defrosting, effectively can remove the frost in vaporizer body 1.
As preferred embodiment, defrosting heater 3 described in the present embodiment is connected with defrosting heater controller, and described defrosting heater gauge tap is arranged on described refrigerator outer wall; Described upper end defrosting heater 4 is connected with upper end defrosting heater controller, and described upper end defrosting heater controller switches is arranged on described refrigerator outer wall.
In the present embodiment, as a kind of preferred version, the both sides, front and back of described vaporizer body 1 are provided with a upper end defrosting heater 4.As further preferred version, before and after described vaporizer body 1, the upper end defrosting heater 4 of both sides includes the upper strata heating tube 41 of connection, middle level heating tube 42 and lower floor's heating tube 43, all be communicated with by vertical heating tube between described upper strata heating tube 41 and middle level heating tube 42 and middle level heating tube 42 lower floor heating tube 43, lower floor's heating tube of both sides, front and back is all communicated with collecting pipe 44.Upper end described in the utility model defrosting heater 4 adopts unique three-decker, and upper strata heating tube 41 and middle level heating tube 42 and vaporizer body 1 are as far as possible many to be contacted, faster heat is passed to vaporizer body 1; Lower floor's heating tube 43, near delivery port, can fall the ice-out of delivery port rapidly, so that defrosting water can successfully be discharged from osculum through collecting pipe 44, thus shortens defrost time, reduction energy consumption of refrigerator.As a kind of preferred version, described vaporizer body 1 is finned tube evaporator, and finned tube is also gilled tube, is add fin on the surface of base tube, makes original heat transfer area obtain expansion.
Fig. 2 is the structural representation of the finned tube evaporator that the utility model detailed description of the invention provides.Concrete, as shown in Figure 2, the finned tube of described finned tube evaporator comprises the first base tube 11, and the surface of described first base tube 11 is provided with the first fin 12.Therefore finned tube is the heat-transfer pipe of band extended surface, and fin itself is extended surface.Owing to increasing fin on the surface of heat exchanger tube, increase the external surface area of heat exchanger tube, thus reach the object improving heat exchange efficiency.
Spoken of in this manual " embodiment ", " another embodiment ", " embodiment ", etc., refer to the specific features, structure or the feature that describe in conjunction with this embodiment and be included at least one embodiment of the application's generality description.Multiple place occurs that statement of the same race is not necessarily refer to same embodiment in the description.Furthermore, when describing specific features, structure or a feature in conjunction with any one embodiment, what advocate is also drop in scope of the present utility model to realize this feature, structure or feature in conjunction with other embodiments.
Although the multiple explanatory embodiment here with reference to utility model is described the utility model, but, should be appreciated that, those skilled in the art can design a lot of other amendment and embodiment, these amendments and embodiment will drop within spirit disclosed in the present application and spirit.More particularly, in the scope of, accompanying drawing open in the application and claim, multiple modification and improvement can be carried out to the building block of subject combination layout and/or layout.Except the modification of carrying out building block and/or layout is with except improvement, to those skilled in the art, other purposes also will be obvious.
