Detailed description of the invention
Be described below in detail embodiments of the invention, the example of described embodiment is shown in the drawings.Be exemplary below by the embodiment be described with reference to the drawings, be intended to for explaining the present invention, and can not limitation of the present invention be interpreted as.
Below with reference to Fig. 1 to Fig. 2, the defroster 100 for refrigerator according to the embodiment of the present invention is described.Defroster 100 is arranged in the air channel 200 of refrigerator, and defroster 100 can comprise case courage 10, evaporimeter 20 and heater 30 substantially.
Particularly, as depicted in figs. 1 and 2, the front surface of case courage 10 is provided with groove 11, and evaporimeter 20 is fixed on case courage 10, and hides groove 11 at least in part, and limit container cavity 40 between evaporimeter 20 and groove 11, heater 30 is fixed in container cavity 40.That is, according to actual needs, evaporimeter 20 can part overlaid groove 11, and evaporimeter 20 also can whole steaming lid groove 11.Because case courage 10 and the frost layer on evaporimeter 20 surface are the non-conductor of heat, therefore, after heater 30 electrified regulation, its heat produced can major part be gathered in container cavity 40, only have minor heat outwards to run off, like this, frost layer absorbs rapid solution after a large amount of heats.Thus, the defrosting efficiency of defroster 100 can be improved, reduce energy consumption.
According to the defroster 100 for refrigerator of the embodiment of the present invention, in the container cavity 40 jointly limited by the groove 11 and evaporimeter 20 that heater 30 are fixed on case courage 10, the heat that heater 30 is produced is not easily to external radiation, improve the surperficial frost layer dissolution velocity of evaporimeter 20, thus, improve defrosting efficiency, reduce energy consumption.
In some embodiments of the invention, as shown in Figure 2, heater 30 can be fixed on before case courage 10, wherein, heater 30 is fixed on the mode of the front surface of case courage 10 and is not particularly limited, and such as, heater 30 can be fixed in the front surface of case courage 10 by mode that is bonding or clamping.But understandable, the present invention is not limited to this.Certainly, on heater 30 roof that also can be located at container cavity 40 or diapire.
In addition, for heater 30 kind also and be not particularly limited, such as in one particular embodiment of the present invention, heater 30 is heater strip, and the efficiency of heating surface of heater strip is high, can improve the defrosting efficiency of defroster 100 thus further.
In other embodiments of the present invention, heater 30 extends along the length (above-below direction as in Fig. 1) of evaporimeter 20 and width (left and right directions as Fig. 1) direction.Thus, the even heat radiation that heater 30 can be made to produce on the surface of evaporimeter 20, thus ensures that the frost layer on evaporimeter 20 surface can be dissolved simultaneously, and then reduces defrosting time, improves defrosting efficiency.
As shown in Figure 2, the rear surface of evaporimeter 20 is close to by heater 30, thus, can shorten heat radiation length, reduces heat losses, improves defrosting efficiency.Certainly, heater 30 can spaced a predetermined distance with evaporimeter 20, and like this, the device 20 local heating intensity that can avoid evaporating on the one hand is too high, and affects evaporimeter 20 performance, on the other hand, evaporimeter 20 can be avoided to hinder heat to external radiation.
In another specific embodiment of the present invention, evaporimeter 20 can be plate-type evaporator, and plate-type evaporator 20 extends to the top orientation of groove 11 from the bottom of groove 11.Plate-type evaporator 20 can hinder heat interior to outer loss from container cavity 40, thus, can improve the defrosting efficiency of defroster 100 further.
In the present invention again some embodiments, as shown in Figure 2, case courage 10 is recessed to form groove 11 backward, and evaporimeter 20 is concordant with the rear wall 60 in air channel 200 towards the one side (i.e. the front surface of evaporimeter 20) of refrigerator compartment rear wall 50.Like this, defroster 100 does not affect the air flow property in air channel 200, thus, can ensure the refrigeration of each room in refrigerator.
The refrigerator (scheming not shown) of embodiment comprises the defroster 100 of first aspect present invention embodiment according to a second aspect of the present invention.Due to, the defroster 100 of first aspect present invention embodiment has the advantage of defrosting efficiency height and energy-saving consumption-reducing.Therefore, high according to the defroster efficiency of the embodiment of the present invention, energy consumption is low.
