The specific meanings of the above terms in the present invention can be understood according to specific conditions.
The defrost heating device 100 according to the ... of the embodiment of the present invention for refrigerator is described referring to Fig. 1-Fig. 5.Such as Fig. 1-
Shown in Fig. 5, the defrost heating device 100 according to the ... of the embodiment of the present invention for refrigerator includes：Heater 1 and ventilative water blocking knot
Structure.
The evaporator 3 of frost-free refrigerator can be arranged in the interlayer between freezing chamber and refrigerating chamber or upper back in case, but
It is without being limited thereto.
Heater 1 is suitable for being arranged in the lower section of the evaporator 3 of refrigerator, and further, collection can be arranged in the lower section of heater 1
Sink 4, when defrost, 1 heat ambient air of heater, hot-air rising melts evaporator 3 and surrounding frost, frost water
The catch basin 4 of the lower section of heater 1 is fallen to by heater 1, it is preferable that ventilative water-retaining structure can be arranged heater 1 with
Between evaporator 3.
In this way, during defrost, the frost water that 1 top of heater is dripped can be dropped on ventilative water-retaining structure, without
It can be in direct contact with 1 surface of heater, so as to avoid the generation of extraordinary noise, improve user experience.
As shown in figures 1 and 3, ventilative water-retaining structure can be structured as the ventilative water retaining cover 2 with wavy cross-section, into one
The wavy cross-section on step ground, water retaining cover 2 of breathing freely may include lug boss 21 and recessed portion 22, and lug boss 21 and recessed portion 22 are saturating
The length direction of gas water retaining cover 2 is arranged alternately.
Preferably, as shown in Figures 2 and 3, the top of each lug boss 21 can be provided with ventilating groove 211, further,
Ventilating groove 211 is flat-shaped rectangular channel, i.e., the width dimensions of ventilating groove 211 are much smaller than the length dimension of ventilating groove 211, while thoroughly
Air drain 211 extends along the width direction of ventilative water retaining cover 2, and ventilating groove 211 runs through lug boss 21.
Thus it is possible, on the one hand, frost water on evaporator 3 flows to catch basin 4, and frost along waveform water retaining cover 2 of breathing freely
Water will not (or considerably less) enter from ventilating groove 211 and flow to 1 surface of heater, on the other hand, the hot-air around heater 1
Evaporator 3 can be flowed to by ventilating groove 211, to play the effect of defrosting.
In some embodiments, as shown in Figure 1, ventilative water retaining cover 2 can be structured as " people " shape structure, and at least partly
Ground is arranged around heater 1, thus can play the role of preventing frost water droplet from falling on 1 surface of heater.
In further embodiments, as shown in figure 4, ventilative water retaining cover 2 can be structured as " people " shape structure, and the water blocking
Cover can have the section consistent with above-mentioned ventilative water retaining cover 2, while the end of ventilative water retaining cover 2 has water blocking flanging 23, this
Sample frost water along herringbone breathe freely water retaining cover 2 flow down when, catch basin 4 can be flowed under the guiding of water blocking flanging 23.
In the third embodiment, as shown in figure 5, ventilative water retaining cover 2 can be structured as " one " shape structure, and the water blocking
Cover can have the section consistent with above-mentioned ventilative water retaining cover 2, while the both ends of ventilative water retaining cover 2 have water blocking flanging 23, this
Sample can play good water conservancy diversion and convenient for hot-air by effect.
In conclusion the defrost heating device 100 according to the ... of the embodiment of the present invention for refrigerator, by 3 He of evaporator
Water-retaining structure of breathing freely is set between heater 1,1 surface of ice water Direct Contact Heating device of 1 top of heater can be prevented and produced
Raw extraordinary noise, to improve user experience.
The present invention also provides a kind of refrigerator, which includes above-mentioned defrost heating device 100, to have noise
Small, the advantages that user experience is good.
