The part of the cold air that is generated by the cooler 44 of cooling chamber 43 is forwards blowed forcibly by fan 46.Refrigerating chamber 37 is by the cold air cooling of discharging from covering 45 outlet.The cold air warp-wise is directed to the bottom of cooler 44 at the return port of the lower openings of cover 45, be carried out heat exchange at cooler 44, passes through fan 46 so that fresh cold air repetitive cycling again.Thus, refrigerating chamber 37 is cooled to proper temperature by the control of refrigerating chamber sensor (not shown).
In addition, the cold air that is discharged to the top of fan 46 is directed to plumbing installation 49 from covering 45 cold gas exhausting outlet 72 through the intercommunicating pore of the first partition wall 41.Then, according to refrigerator temperature sensor 67 indoor temperatures be design temperature when above, the refrigerating chamber baffle plate 50a of retaining device 50 opens, thus, the cold air that is discharged to refrigerating chamber 35 is discharged from from the outlet 35a of refrigerating chamber by refrigerating chamber air supply duct 48a, with indoor cooling.Cold air after the circulation becomes the air with the contained moisture of the air in the refrigerating chamber 35 and/or reserve, is directed to return port 35b.Then, the refrigerating chamber Returning pipe 51a of cold air by plumbing installation 49, the cold air return path 71 that consists of by the back face wall by cover 45 and cooling chamber 43.Then, cold air is directed to the bottom of cooler 44 from cold air return port 77, carries out heat exchange with cooler 44, and fresh cold air is forced to blow by fan again.
Because by fan 46 cold air is forced to blow to the refrigerating chamber air supply duct 48a that is communicated with cooler 44, discharge cold air by the refrigerating chamber air supply duct 48a in the plumbing installation 49 to refrigerating chamber 35, and the switching by refrigerator temperature sensor 67 control refrigerating chamber baffle plate 50a, even so be positioned at the position of leaving cooler 44, also can be with the indoor design temperature that is controlled at of refrigerating chamber 35.
In addition, in the situation that be more than the design temperature because switching chamber temperature sensor 68 makes indoor temperature, open the switching chamber baffle plate 50b of retaining device 50, by switching chamber air supply duct 48b, discharge cold air from the outlet 36a of the switching chamber that is arranged on the position higher than the upper surface open section of upper drawer 69 to switching chamber 36, Quilt with air conditioning imports in the upper drawer 69.In addition, also discharge cold air from the outlet 36b that is arranged on the position higher than the upper surface open section of this bottom drawer 70, the back face wall of upper drawer 69 is played a role as the guide member that flows that limits cold air, cold air is imported in the bottom drawer 70.Quilt with air conditioning guiding return port 36c after switching chamber 36 interior circulations, 51b returns connected entrance 59 by switching chamber by the switching chamber Returning pipe, be directed to the bottom of cooler 44 from cold air return port 77 by the shunt conduit 76 that forms at cover 45, carry out heat exchange with cooler 44, the cold air that carries out after the heat exchange is forced to blow by fan again.
Because by fan 46 cold air is forced to blow to the switching chamber air supply duct 48b that is communicated with cooler 44, make cold air pass through plumbing installation 49 interior to switching chamber 36 discharges, and the switching by switching chamber temperature sensor 68 control switching chamber baffle plate 50b, even so be positioned at the position of leaving cooler 44, also can be with the indoor design temperature that is controlled to be of switching chamber 36.
In plumbing installation 49, refrigerating chamber air supply duct 48a, switching chamber air supply duct 48b and refrigerating chamber Returning pipe 51a be laterally side by side configuration about upper and lower extends upward also, and switching chamber Returning pipe 51b forms in the place ahead of refrigerating chamber Returning pipe 51a.
Therefore, refrigerating chamber air supply duct 48a and switching chamber air supply duct 48b are configured in the approximate centre position of the width of plumbing installation 49, and dispose refrigerating chamber Returning pipe 51a and switching chamber Returning pipe 51b with respect to heat insulating box 31 at fore-and-aft direction in a side, so so can make because the distance that disposes 33 in the plumbing installation 49 of the idle space that the water supply piping 55 that is connected with supply tank 53 and distribution incorporating section 52 become switching chamber 36 rears and interior case at opposite side diminishes, can guarantee that the depth size of switching chamber 36 is larger.
In addition, refrigerating chamber air supply duct 48a so can reduce the duct resistance in the pipeline, guarantees to blow to the air quantity of refrigerating chamber 35 till the individual paths 63 to the refrigerating chamber 35 in the plumbing installation 49 of switching chamber 36, form pipeline in the direction of approximate vertical.
In addition, filling-foam heat-barrier material 34 forms the first partition wall 41 and the second partition wall 42 at heat insulating box 31, afterwards, between the first partition wall 41 and the second partition wall 42, at the back side of switching chamber 36 configuring pipes device 49, can form simply thus the pipeline configuration of switching chamber 36.
Switching chamber 36 can switch to design temperature 4 ℃ refrigerated storage temperature territory from-18 ℃ cryogenic temperature territory.This can realize by the rate of opening wide of correspondingly controlling switching chamber baffle plate 50b with design temperature.
Particularly the design temperature in switching chamber 36 is set in the situation of the temperature field lower than refrigerated storage temperature, and the cold air of discharging from outlet 36a, the 36b of switching chamber is imported in the switching chamber Returning pipe 51b by return port 36c.Cold air by refrigerating chamber Returning pipe 51a is because higher than the temperature of the cold air by switching chamber Returning pipe 51b, so there is the problem that produces dewfall at the pipe surface of refrigerating chamber Returning pipe 51a, in the special situation that the temperature degree is low outside, the possibility that exists dewfall to freeze.In addition, the possibility that also exists dew to flow through in the refrigerating chamber Returning pipe 51a, freeze at return path 71.Therefore, can heat to make the dew evaporation that produces by the aluminium foil heater 57 that utilization sticks on refrigerating chamber Returning pipe 51a, prevent freezing in the pipeline.
In addition, by utilizing shunt conduit 76 that cold air is not mixed in the upstream portion shunting of cold air return path 71, can bring into play and prevent from not flowing to the below and returning connected entrance 59 adverse currents to switching chamber by the cold air that refrigerating chamber Returning pipe 51a comes, interception from from the switching chamber return port 36c of plumbing installation 49 to switching chamber 36 interior adverse currents, prevent that as adverse current pipeline from working, stop refrigerating chamber to return cold air and return connected entrance 59 from switching chamber return port 36c to switching chamber 36 adverse currents by switching chamber, can effectively switching chamber 36 be cooled to proper temperature, and can Antidewing etc.
In addition, expose an end from cooler 44 on the perspective plane end of Defrost heater 47, by in the cold air return port 77, be extended down to cold air return path 71 and configure interiorly, so when defrosting, can utilize the heat of heater to heating in the return path 71, so can improve and Antidewing and freezing, can improve reliability.
Because refrigerating chamber Returning pipe 51a and switching chamber Returning pipe 51b are by being communicated with the below of cooler 44 with temperature field refrigerating chamber 37 zones lower than switching chamber 36 and refrigerating chamber 35, so compare with the temperature field of refrigerating chamber 37, the refrigerating chamber Returning pipe 51a that cold air temperature is the highest is configured in the mode of the position of leaving refrigerating chamber 37, can reduce the problem that is cooled in the refrigerating chamber Returning pipe 51a and produces dewfall, further freeze in the refrigerating chamber Returning pipe 51a.
Therefore, by can be configured in from the temperature near the temperature of refrigerating chamber 37 the place ahead of refrigerating chamber Returning pipe 51a to the switching chamber Returning pipe 51b of the switching chamber 36 of setting near the temperature of temperature of refrigerating chamber, can reduce the dewfall in the refrigerating chamber Returning pipe 51a and freeze.
