Be provided with cold air path 22 in the rear side of refrigerating chamber 8, and be provided with partition wall portion 23 between refrigerating chamber 8 and cold air path 22.Be provided with reception room 24 in the rear side of cold air path 22, described reception room 24 contains cooler 18 described later etc.Between reception room 24 and cold air path 22, be provided with partition wall portion 25.Reception room 24 is formed by the casing that comprises partition wall portion 25 and back face wall 21, and reception room 24 extends in short transverse.
Be provided with cooling duct 27 in the rear side of refrigerating chamber 6, between cooling duct 27 and refrigerating chamber 6, be provided with partition wall portion 26.
Cooling duct 27 is connected with cold air path 22, and is provided with baffle plate 29 and fan 28 between cooling duct 27 and cold air path 22.
Cooling device generates the cold air of supplying with to refrigerating chamber 6, ice-making compartment 7, refrigerating chamber 8 and vegetable compartment 9.Cooling device comprises: compressor 17, compression refrigerant gas; Condenser (not shown), makes the refrigerant gas condensation of the HTHP that compressor 17 compresses; Expander (not shown), passes through for the refrigerant liquid of condenser condenses; Cooler (evaporimeter) 18, makes the refrigerant liquid evacuator body of pressure drop in expander; And reservoir 19, be connected in cooler 18 and compressor 17.
Compressor 17 is housed in the canyon 16 that the rear side of vegetable compartment 9 forms.Cooler 18 is housed in reception room 24, and is positioned at the top of canyon 16.Reservoir 19 is also housed in reception room 24, and is located at the top of cooler 18.In reception room 24, also contain control part 30.
In the medial surface of reception room 24, be positioned in the part above cooler 18 and be formed with peristome 31, fan 32 is arranged on described peristome 31.The below of cooler 18 is provided with heater 33, between heater 33 and cooler 18, disposes heater housing 34.
In the time driving cooling device, in reception room 24, be positioned at cooler 18 ambient airs and be cooled.Air in the reception room 24 that fan 32 makes to be cooled flows into cold air path 22.On cold air path 22, be formed with cold air mouth etc., so that cold air enters in ice-making compartment 7 and refrigerating chamber 8.
Fan 28 makes the cold air that is supplied to cold air path 22 flow into cooling duct 27.In partition wall portion 26, be formed with the cold air mouth that leads to refrigerating chamber 6, cold air enters in refrigerating chamber 6 from described cold air mouth.On the bottom surface side of refrigerating chamber 8, be provided with the backward channel 35 that is communicated with reception room 24, vegetable compartment 9 is also provided with the backward channel 36 that is communicated with reception room 24.
By refrigerating chamber 6, ice-making compartment 7, refrigerating chamber 8 and vegetable compartment 9 etc. and cooling object is carried out to cooled air, enter in reception room 24 from backward channel 35,36, the device 18 that is again cooled is cooling.
The air entering in reception room 24 from backward channel 35 and backward channel 36 contains large quantity of moisture sometimes.If it is cooling to utilize cooler 18 to carry out this air, on cooler 18, can adhere to frost.
In order to remove the frost adhering in cooler 18 grades, control part 30 makes the running that defrosts of cooling device and heater 33 on the opportunity of regulation.In defrosting running, stop driving cooling device, and drive heater 33.By driving heater 33, the frost adhering on the surface of cooler 18 grades is removed.
Fig. 2 is the rearview that represents cooler 18 and reservoir 19, is the rearview of observing from the rear side of cold room 1.As described in as shown in Fig. 2, cooler 18 comprises the refrigerant pipe 37 of the cold-producing medium that circulates, and is arranged on the multiple cooling fins 38 on refrigerant pipe.
Refrigerant pipe 37 extends downwards from 39 serpentine bend limits, limit, initial end, and the limit serpentine bend limit extension upward from below.The initial end 39 of refrigerant pipe 37 is connected with the capillary as expander performance function, and from capillary to refrigerant pipe 37 the supply system cryogens.If cold-producing medium enters in refrigerant pipe 37, cold-producing medium is vaporized, and is positioned at cooler 18 ambient airs and is cooled by cooling fin 38 grades.Final end 40 is connected with as the reservoir of gas-liquid separator performance function (gas-liquid separator) 19, and liquid cold-producing medium storage is stayed in reservoir 19, and gasiform cold-producing medium is sent to compressor 17.
Fig. 3 is the exploded perspective view that represents reception room 24, cooler 18 and fan 32 etc., and Fig. 4 is the stereogram that represents reception room 24, cooler 18 and fan 32 etc.In addition, Fig. 3 is the stereogram of observing from the face side of cold room 1, and Fig. 4 is the stereogram of observing from the rear side of cold room 1.
As shown in Figure 3 and Figure 4, back face wall 21 comprises: main wall portion 44, is formed as tabular; Side wall portion 41, is formed on the first type surface of main wall portion 44, and extends in short transverse; Side wall portion 42, with side wall portion 41 formation spaced apart; And upper wall portions 43, be arranged to connect the top portion of side wall portion 41 and side wall portion 42.
Partition wall portion 25 is configured to cover side wall portion 41, side wall portion 42 and upper wall portions 43.In other words, the casing of formation reception room 24 comprises side wall portion 41, side wall portion 42, upper wall portions 43 and partition wall portion 25.Partition wall portion 25 has par 45, and is connected the rake 46 arranging with par 45.Along with from below upward, rake 46 tilts in the mode of swinging to main wall portion 44 sides.
On rake 46, be formed with peristome 31, in peristome 31, dispose fan 32.Fig. 5 is the cross-sectional side view that represents the configuration status of fan 32 and cooler 18 etc.As described in as shown in Fig. 5, along with upward, fan 32 is to approach the mode tilted configuration of main wall portion 44.
If the distance between fan 32 and partition wall portion 23 is distance L 1, the distance between partition wall portion 25 and partition wall portion 23 is distance L 2.And distance between fan 32 and main wall portion 44 is distance L 3.Particularly, distance L 1 is that the virtual axis O1 of rotary centerline by fan 32 and the intersection point of partition wall portion 23 are to the distance between fan 32.Distance L 3 is that intersection point by the virtual axis O1 of the center of rotation axis of fan 32 and main wall portion 44 is to the distance between fan 32.Conventionally,, if fan approaches while being positioned at nearby wall around of fan, the draft capacity of fan significantly reduces.Therefore, for the fan 32A towards horizontal direction, when fan 32 is erected by rotary centerline, and fan 32 is studied.If the distance between fan 32A and main wall portion 44 is distance L 6.Now, fan 32A is arranged on the position that distance L 6 equates with described distance L 3.
Partition wall portion 23 when partition wall portion 23A shown in dotted line represents to make partition wall portion 23 away from fan 32A, and make the distance L 4 of partition wall portion 23A and fan 32A equal described distance L 1.Like this, because distance L 1 is consistent with distance L 4, and distance L 3 is consistent with distance L 6, so the draft capacity of the draft capacity of fan 32 and fan 32A is unanimous on the whole.On the other hand, partition wall portion 23A than partition wall portion 23 to refrigerating chamber 8 one side shiftings shown in Fig. 1 the part of distance L 5.Hence one can see that, by fan 32 is tilted, in the case of maintaining the draft capacity of fan 32, can strengthen the volume of refrigerating chamber 8 cooling chambers such as grade shown in Fig. 1.
