Description
Technical field
This utility model is related to a kind of refrigerator freezing fan defrost heating arrangement.
Background technology
With social progress, the raising of people's living standard, frost-free refrigerator has progressed into common people house.No rime ice
The wherein maximum advantage of case can be achieved on refrigerator automatic defrosting, therefore the defrost reliability consideration to frost-free refrigerator is just progressively gone up
It has been raised to a new level.
At present, common wind cooling refrigerator freezing fan, in actual running, flabellum all more or less exists a little
Frost, but can be eliminated by the waste heat of refrigerator defrosting heater.But for relatively conventional wind cooling refrigerator, by freezing
Install again in air channel freeze can realize refrigeration compartment temperature into parts such as, return air air doors will to the wide cut alternating temperature of freezing from cold preservation
Ask.With for the wind cooling refrigerator of two compartments it is generally the case that upper compartment is as refrigerator room, lower compartment is freezing compartment.?
Under new design requirement, upper compartment can be changed into freezing compartment, and temperature can reach -12 DEG C or lower, and lower compartment can change
For refrigerator room, temperature rises to 5 DEG C from -18 DEG C.When vaporizer is located at lower compartment, this lower compartment temperature is cut at 5～-18 DEG C
During changing, when using for preventing bottom freeze compartment from doing refrigerator room, because the heat transfer types such as conduction of heat cause bottom compartment
The compartment temperature that internal-external temperature difference leads to greatly is low, does not reach the requirement using as refrigerator room, therefore is provided with and freezes into, return air
The freezing air channel of door is thicker.Because bottom compartment temperature is in 5～-18 DEG C of handoff procedures, between bottom, indoor humidity ratio is relatively
Greatly, during actual refrigerating operaton, frost more conventional wind cooling refrigerator in freezing fan surface freezes the many of fan surface knot, and
And for ensureing that the temperature of bottom compartment reaches cold preservation design temperature state, entering in freezing air channel, return air door leads to freeze
The more conventional refrigerator of air channel structure is complicated, and during conventional defrost, thermal convection current effect weakens, using the waste heat defrosting of defrosting heater
Effect is deteriorated.In the case of above new problem, it is difficult to eliminate the frost on freezing fan with conventional defrosting control program.With
The prolongation of run time, the frost not eliminated on fan surface will be gradually increased, run for a long time and will lead to fan surface
Frost very serious, fan will run slowly, hydraulic performance decline, finally cause refrigerator overall performance decline.

It is uniformly distributed.
It is straight that the geometric center of the air inlet of described freezing fan, fan heater and freezing fan housing is respectively positioned on same level
On line.
Described fan heater includes the circular heating tube do not closed, described fix bar one end pass through buckle structure with described
Circular heating tube is detachably connected, the other end is fixed by screws on described freezing fan housing.
This utility model has the advantage that compared to existing technology
1st, a kind of refrigerator freezing fan defrost heating arrangement that this utility model provides, its fan heater is directly arranged in
The air inlet of freezing fan housing, and fan heater is located at the both sides of air outlet respectively with freezing fan, fan heater is released
The heat overwhelming majority put all is used for freezing the frost of fan or ice slag melts used, heat utilization efficiency height, and power consumption is few.
2nd, a kind of refrigerator freezing fan defrost heating arrangement that this utility model provides, it is heated with the defrost on vaporizer
The heat time heating time of base of evaporator defrosting heater when device uses cooperatively, can be shortened, reduce the heating energy consumption of defrosting heater,
Improve the reliability of defrosting heater further.
3rd, a kind of refrigerator freezing fan defrost heating arrangement that this utility model provides, structure is simple, easy accessibility.
Brief description
Fig. 1 is structural representation of the present utility model.
The structural representation that Fig. 2 is used cooperatively with defrosting heater for this utility model.
In figure label: 1 freezing fan, 2 fan heaters, 3 freezing fan housings, 4 fix bars, 5 air inlets, 6 screws, 7 evaporations
Device, 8 defrosting heaters, 9 back inner bags, 10 freezing inlet air door, 11 freezing return air air doors.
Specific embodiment
Below embodiment of the present utility model is elaborated, the present embodiment is being front with technical solutions of the utility model
Put and implemented, give detailed embodiment and specific operating process, but protection domain of the present utility model does not limit
In following embodiments.
Referring to Fig. 1, present embodiment discloses a kind of refrigerator freezing fan defrost heating arrangement, including freezing fan housing 3, freezing
Fan 1, freezing fan housing 3 is provided with air inlet 5, and freezing fan 1 is arranged on freezing fan housing 3 and faces entering of freezing fan housing 3
