Below, the mobility status of cold air in the said structure freeze cycle is described in conjunction with Fig. 9 of refrigerator 10.
At first, illustrate by the mobility status that refrigerates the cold air that cools off with evaporimeter 50.
Cold air by refrigeration is cooled off with evaporimeter 50 is admitted to the refrigeration branch space 78 that is positioned at vegetable compartment 16 rears from the front side that refrigerates with pressure fan 54.The top of this refrigeration branch space 78 is connected with the refrigeration pipeline 80 that is located at refrigerating chamber 14 back sides, thereby cold air is delivered to this refrigeration pipeline 80.As shown in Figure 8, refrigeration pipeline 80 is divided into two strands in the bottom of refrigerating chamber 14, roughly is the U font.Front at refrigeration pipeline 80 is provided with the blow-off outlet 82 that every predetermined distance blows out cold air, and cold air is blown into the refrigerating chamber 14 from these blow-off outlets 82.The below (with reference to Fig. 9) of the cold air that refrigerating chamber 14 is cooled off by cooling chamber 26, storage tank 44 flow into be located at refrigeration with pressure fan 54 and refrigeration with the return-air duct 84 of evaporimeter about 50, blow out to the below of refrigeration with evaporimeter 50.And this cold air cools off with evaporimeter 50 with refrigeration again, arrives the position of refrigeration with pressure fan 54.
In addition, the fresh-keeping cover 29 of cold air from refrigeration branch space 78 along vegetable compartment 16 cools off (with reference to Fig. 9) to vegetable compartment 16.This cold air flows in the bottom of vegetable container 28 in the past backward, arrive return air openings portion 88 and in refrigeration with circulation in the evaporimeter 50.
The following describes mobility status by the freezing cold air that cools off with evaporimeter 52.
By the freezing cold air that cools off with evaporimeter 52, arrive freezing branch space 90.The top of this freezing branch space 90 communicates with ice maker 34, thereby cold air blows out to ice maker 34 from this top.In addition, the bottom of freezing branch space 90 with in the hole 33 of the backplate upper shed of the refrigerated container 32 of refrigerating chamber 22 with communicate above the refrigerated container 32, thereby cold air blows out from this bottom to refrigerated container 32 inside.

Fig. 5 represents the cutaway view of triple valve 68, is the so-called electromagnet structure that is made of coil 102, magnet 104, plunger 106 etc.Be provided with pin 108 in the bottom of plunger 106, by to coil 102 excitations, pin 108 just is driven to the below, overcomes spring 112 elastic force and drives valve body 110 downwards.Under this state, cold-producing medium is just used evaporimeter (R エ バ) side from drier one effluent to refrigerating.In addition, when plunger 106 was replied, valve body 110 was replied upward, cold-producing medium just from drier one effluent to freezing usefulness evaporimeter (F エ バ) side.116 is that valve seat is used in refrigeration among the figure, the 118th, and the freezing valve seat of using.
For the triple valve 68 that switches refrigerant flow path, because in its configuration aspects and the situation of small trash folder between valve body 110 and valve seat 116,118 in the freeze cycle arranged, so exist leakage rate to a certain degree.
Therefore, in the present embodiment, set in advance the refrigeration that is installed in the refrigerant flow path shown in Figure 1 capillary 70 and freezing amount of restriction difference with the cold-producing medium in the capillary 72.
That is to say, the refrigeration that is connected with evaporimeter 50 by handle and refrigeration with the amount of restriction of capillary 70 be provided with compare loose with the amount of restriction of the freezing freezing usefulness capillary 72 that is connected with evaporimeter 52, cold-producing medium is used in the evaporimeter 50 in refrigeration flowed, cold-producing medium is flowed freezing using in the evaporimeter 52.
For example, for desire is cooled off refrigerating chamber 14, when refrigerant flow path being utilized triple valve 68 switch to when refrigerating the stream that is connected with evaporimeter 50, producing the occasion of leaking with freezing freezing usefulness capillary 72 sides that are connected with evaporimeter 52, because freezing amount of restriction with capillary 72 1 sides is more tight with the amount of restriction of capillary 70 than refrigeration, so cold-producing medium is difficult to use capillary 72 1 side flow to freezing, thereby cold-producing medium is to refrigeration evaporimeter 50 1 side flow.
On the contrary, for desire is cooled off refrigerating chamber 22, when refrigerant flow path being utilized triple valve 68 switch to the freezing stream that is connected with evaporimeter 52, producing the occasion of leaking with refrigeration with capillary 70 sides with the refrigeration that evaporimeter 50 is connected, because refrigeration is looser than freezing amount of restriction with capillary 72 with the amount of restriction of capillary 70, therefore, though cold-producing medium flows with evaporimeter 50 to refrigeration, but because refrigeration shuts down with pressure fan 54, so cold-producing medium does not carry out heat exchange in refrigerating with evaporimeter 50, but with through directly to the freezing cold-producing medium interflow that refrigerating chamber 22 is connected with capillary 72, evaporate in freezing with evaporimeter 52, heat exchange.
So, in the present embodiment, even producing, triple valve 68 leaks, when refrigerating chamber cools off and when refrigerating chamber cools off, also can be respectively reach in evaporimeter 50 freezing and flow through most cold-producing medium in evaporimeter 52 in refrigeration, can cool off respectively, thereby can prevent to produce loss refrigeration, freezing each zone.

In this case, though that refrigeration should rise in original cooling with the temperature of evaporimeter 50 is about more than 0 ℃, owing to lower, so can detect than it.Produce a kind of of the possibility of leaking as triple valve 68, can consider following situation: when being pressed on the valve seat 116,118 when mobile valve 110, the rubbish in the freeze cycle just embeds therebetween, just produces the gap between valve body 110 and the valve seat 116,118.
At this moment, valve body 110 is opened certain hour, 10 seconds for example cold-producing medium is flowed between valve body 110 and valve seat 116,118, wash away behind the rubbish mobile valve 110 again, be pressed on the valve seat 116,118, then can improve its compactness.This control can be undertaken by control part shown in Figure 1 120.In addition, also (2～3 times) this action repeatedly several times.
The 3rd embodiment
And, refrigeration being remained in operation under the situation of certain hour (for example 5 minutes) with pressure fan 54 when when the refrigerating chamber state of cooling switches to the no state of cooling, refrigeration usefulness evaporimeter 50 is risen near 0 ℃ by the indoor air heat of refrigerating chamber 14.
But, producing the occasion of leakage with the refrigeration that evaporimeter 50 is connected with capillary 70 sides with refrigeration, as if stopping refrigeration, then refrigerate the temperature of using evaporimeter 50 and descend with pressure fan 54 runnings.This situation is identical with the 1st embodiment, eliminates valve by mobile valve 110 and leaks.
