Position connect with return air straight section 152, connect with cooling chamber return air inlet in order to bypass the first side wall 121.What is be consequently formed returns
The length in wind air duct 150 is smaller, compared with little airflow resistance, reduces energy loss.
Space between wind inlet channel 140 and the outer wall and shell of refrigerating chamber 120 is filled with thermal insulation material, return airway
Space between 150 and the outer wall and shell of refrigerating chamber 120 is filled with thermal insulation material.It also is understood as, 140 He of wind inlet channel
Return airway 150 is respectively positioned in the foaming layer between refrigerating chamber 120 and shell, to avoid wind inlet channel 140 and return airway 150
Influence to 120 temperature of refrigerating chamber, and avoid the loss of refrigeration capacity of wind inlet channel 140.
Fig. 5 is according to the front view of the refrigerating chamber 120 of the refrigerator 100 of the utility model one embodiment, and Fig. 6 is Fig. 5
A-A sectional views, Fig. 7 are the A-A sectional views of electric flap 160 in Fig. 4.
Such as Fig. 5 to Fig. 7, heating element 126 is additionally provided on ice making evaporator 123.Heating element 126 can be periodically to ice making
Evaporator 123 carries out heating defrost.Specifically, heating element 126 can be heater strip or heating plate, and heating element 126 can be arranged
It is upwardly extended in the lower part of ice making evaporator 123, and by the side of ice making evaporator 123.Heating element 126 can also be coiled in system
On the surface of ice evaporator 123, to increase the contact area with ice making evaporator 123, accelerate the defrost of ice making evaporator 123.
Thus avoiding ice making evaporator 123 in use for some time influences the heat exchange property of ice making evaporator 123 because of frosting.
As shown in Figure 5,6, the bottom of ice machine cooling chamber 122 is formed with osculum, and the foaming layer of babinet 110 is (outside babinet
Space between shell and storing compartment is filled with foaming layer) in be disposed with the drainpipe 127 being connected to osculum, drainpipe 127
It is extended to by the position being connected to osculum in the drip tray of the bottom of babinet 110, the defrosting water of ice making evaporator 123 is through draining
Pipe 127 is flow in drip tray.
Referring again to Fig. 4, electric flap 160 is provided in the air inlet straight section 142 of wind inlet channel 140, electric flap 160 is matched
It is set to when heating element 126 carries out heating defrost to ice making evaporator 123, straight section 142 is entered the wind in controlled closing, to avoid ice making
Hot gas around evaporator 123 flows through wind inlet channel 140 and enters in ice-making compartment 131, to avoid the ice cube in ice machine 132 from melting
Change adhesion and so that ice cube is difficult to be detached from from ice machine 132, and can avoid the part in the ice storage area of 132 lower part of ice machine
Ice melting adhesion and make ice storage area in ice cube be difficult to down fall in distributor.
In ice-making process, electric flap 160 is in the open state always, is flowed with ensureing that cold air flows through wind inlet channel 140
Into ice-making compartment 131.
As shown in fig. 7, electric flap 160 may include air door ontology 162 and the motor 161 with output shaft in general manner.
The output shaft of motor 161 is substantially parallel with the width direction of wind inlet channel 140.Heating element 126 carries out ice making evaporator 123
When heating defrost, 161 controlled operation of motor, air door ontology 162 drives the output shaft around motor 161 to rotate by motor 161, will
Wind inlet channel 140 is closed, and thermal current is avoided to be flowed in ice-making compartment 131 from wind inlet channel 140.
The width of air door ontology 162 is roughly the same with the thickness of wind inlet channel 140, the height and air inlet of air door ontology 162
The width in air duct 140 is roughly the same, to ensure that air door ontology 162 can completely close wind inlet channel 140.
The rear wall inside of the refrigerator 100 of the present embodiment, refrigerating chamber 120 is formed with ice machine cooling chamber 122, is located at refrigerating chamber
The cold of ice making evaporator 123 is directly delivered at ice machine 132 by the wind inlet channel 140 of 120 outer wall, simplifies air duct
Structure shortens the path length of cold airflow flowing, reduces distinguished and admirable resistance, considerably increase at ice machine 132
Air quantity, and loss of refrigeration capacity is reduced, improve ice making efficiency.Furthermore by the way that heating element is arranged on ice making evaporator 123
126, can heating defrost periodically be carried out to ice making evaporator 123, avoid ice making evaporator 123 after a period of operation, because of knot
Heat exchange property that is white and influencing ice making evaporator 123.
Further, in the refrigerator 100 of the present embodiment, wind inlet channel 140 and return airway 150 may be contained within refrigerating chamber
The outside of 120 outer walls is accelerated the cycle of cold, is improved using the wind inlet channel 140 and return airway 150 of special arrangement
The transfer efficiency of cold.
Further, in the refrigerator 100 of the present embodiment, by the way that electric flap 160 is arranged in entering the wind straight section 142, when
When heating element 126 carries out heating defrost to ice making evaporator 123, straight section 142 is entered the wind in 160 controlled closing of electric flap, to keep away
Exempt from the hot gas around ice making evaporator 123 to flow through in the entrance ice-making compartment 131 of wind inlet channel 140, to avoid in ice-making compartment 131
Ice melting stick together in part and the problem of cause ice cube to be difficult to be detached from from ice machine 132.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this practicality is new
The range of type is understood that and regards as to cover other all these variations or modifications.
