At this point, the cold air for cooling ice temperature fresh-keeping room 22 is overflowed from ice temperature fresh-keeping room container 44, in ice temperature fresh-keeping room 22 Cold air return path portion (ice temperature fresh-keeping side) 46 with from refrigerating chamber 14 cold air collaborate, from the top plate for being set to refrigerating chamber 21 The refrigeration cold air return port (micro- jelly side) 55 of component 50 passes through the cold air return path portion (micro- jelly side) 56 at 21 rear of refrigerating chamber, from Cold air collaborates return port 57 and returns to cooling chamber 23 via refrigerating chamber return duct 58.

In addition, the cold air of refrigerating chamber 21 is overflowed from refrigerating chamber's container 52, to the cold air return path portion at 21 rear of refrigerating chamber (micro- jelly side) 56 flow, with from refrigerating chamber 14 and ice temperature fresh-keeping room 22 cold air interflow and from cold air interflow return port 57 via Refrigerating chamber return duct 58 returns to cooling chamber 23.

Like this, the freezer 90 of present embodiment can make the cold air of refrigerating chamber 14, ice temperature fresh-keeping room 22 cold air and After the cold air of refrigerating chamber 21 is via cold air return port (ice temperature fresh-keeping side) 45, the ice temperature fresh-keeping room 22 being set in refrigerating chamber 14 The cold air return path portion (ice temperature fresh-keeping side) 46 of side, cold air return port (micro- jelly side) 55, the rear for being set to refrigerating chamber 21 Cold air return path portion (micro- jelly side) 56 and cold air interflow return port 57 return to cooling chamber 23.It therefore, there is no need to along refrigeration Separately setting makes the cold air of each room (ice temperature fresh-keeping room 22 and refrigerating chamber 21) return to cooling chamber 23 to room pipeline 28 in refrigerating chamber 14 Pipe section.Therefore, the internal volume of refrigerating chamber 14 can be made to increase amount corresponding with the pipeline for not needing separately to be arranged, Neng Gouleng But more food materials are saved.

In addition, the cold air return path portion of cold air interflow return port 57 is flowed to via ice temperature fresh-keeping room 22 from refrigerating chamber 14 The mainstream of cold air in (micro- jelly side) 56 is located on the line of cold air return port (micro- jelly side) 55 and cold air interflow return port 57.It should Cold air includes the cold air from ice temperature fresh-keeping room 22 and the cold air from refrigerating chamber 21, but its major part is from refrigerating chamber 14 Cold air.In the freezer 90 of present embodiment, collaborate in the cold air return port (micro- jelly side) 55 and cold air of mainstream cold air flow It is provided with refrigerator temperature sensor 59 (6 and Figure 17 referring to Fig.1) between return port 57, therefore, can accurately detect cold Hide the temperature of room 14.Therefore, accurately the temperature of refrigerating chamber 14 can be controlled as set temperature.

On the other hand, 60 cold air being set in refrigerating chamber 21 of refrigerating chamber's temperature sensor (low temperature chamber temperature sensor) returns The cold airflow for going back to passage portion (micro- jelly side) 56 becomes the cold air return port (micro- jelly side) 55 and cold air interflow return port 57 of mainstream Part other than on line, in the present embodiment, as shown in Figure 16 and Figure 17, be set to it is when observing from the front freezer 90, Clip the diagonal part that refrigerating chamber pipeline 28 and refrigerator temperature sensor 59 are in opposite side in the lateral direction.According in this way Structure, can accurately detect the temperature of refrigerating chamber 21, be accurately proceed control.That is, clip refrigerating chamber pipeline 28 with The cold air that refrigerator temperature sensor 59 is in the refrigerating chamber 14 of the diagonal part of opposite side is few, the cold air of flowing in the part Most of is the cold air in refrigerating chamber 21, and in the part, the cold air in refrigerating chamber 21 becomes the state of floating.Therefore, according to this The structure of sample can accurately detect the temperature in refrigerating chamber 21, can be accurately proceed temperature control.

On the other hand, ice temperature fresh-keeping room 22 by the cold emission from refrigerating chamber 21 as described above, be cooled to than cold The low temperature of room temperature is hidden, when the cooling temperature of refrigerating chamber 21 changes, the temperature of ice temperature fresh-keeping room 22 is easily affected by it and becomes Change.

But in the freezer of present embodiment 90, can based on the output from ice temperature fresh-keeping room temperature sensor, It is by the temperature control of ice temperature fresh-keeping room 22 by unlatching/22 bottom surface of closing ice temperature fresh-keeping room heater for regulating temperature 49 Set temperature can be accurately proceed the temperature control of ice temperature fresh-keeping room 22.

The temperature control of ice temperature fresh-keeping room 22 and refrigerating chamber 14 and refrigerating chamber 21 are same, by setting air door and can be opened and closed Air door carries out the cool-air feed to ice temperature fresh-keeping room 22, but the situation needs air door installation space, and volume of refrigerating chamber is caused to subtract Small or freezer is enlarged.But it if being set as heater mode as present embodiment, does not need for air door to be arranged Space and access structure, can simply and not carry out the control of the temperature of ice temperature fresh-keeping room 22 with reducing volume of refrigerating chamber.

In addition, refrigerator temperature sensor 59 and refrigerating chamber's temperature sensor 60 are installed on the pipeline cover of refrigerating chamber pipeline 28 28b, thus by by pipeline cover 28b to being installed in refrigerating chamber, can be by refrigerator temperature sensor 59 and refrigerating chamber's temperature Degree sensor 60 is assembled in specified position.Therefore, with assembled conduit cover 28b and each sensor (refrigerator temperature sensor respectively 59 with refrigerating chamber temperature sensor 60) the case where compare, its workability can be greatly improved, improve productivity.

In addition, the freezer 90 of present embodiment is equipped with deodorization unit as shown in Figure 21~Figure 23, in pipeline cover 28b 61, therefore, the assembling of deodorization unit 61 becomes easy, and can further increase productivity.Further, by the way that deodorization unit is arranged 61, the smell being transferred in cold air from the food materials in refrigerating chamber 14 can be removed, the freezer of health is obtained.

Further, the cold air return port (ice temperature fresh-keeping side) 45 of the structure cold air return path in refrigerating chamber 14 is (referring to figure 15) and cold air return port (micro- jelly side) 55, with cold air interflow return port 57 be set as when observing from the front freezer 90 on a left side Position is staggered in right direction.Therefore, even if the clast that food materials etc. occur is returned from cold air return port (ice temperature fresh-keeping side) 45 or cold air It answers back the case where being fallen etc via cold air return port (ice temperature fresh-keeping side) 45 of (micro- jelly side) 55, can also prevent them from falling within cold Block cold air interflow return port 57 on the return port 57 of gas interflow or reduce the opening area etc. of cold air interflow return port 57, energy Enough span length's phases maintain good cold air to return to performance.

Finally, the cooling and cold air return action to freezing chamber 18 are illustrated.

As shown in Fig. 4, Fig. 5 and Fig. 9, the cold air of the cold air in the downstream side from cooling fan 25 from freezing chamber backplate 32 Blow-off outlet 63 is supplied to freezing chamber 18 and is cooled to.Cold air blow-off outlet 63 on the left of the top layer in cold air blow-off outlet 63 Cold air be fed into ice-making compartment 16, the cold air of the cold air blow-off outlet 63 on the right side of top layer is fed into switching chamber 15, and Cooling each room.The cold air of freezing chamber 18, ice-making compartment 16 and switching chamber 15 is cooled from the freezing for the lower part for being set to freezing chamber 18 Cold air return port 64 returns to cooling chamber 23.

Herein, it in the freezer of present embodiment 90, as shown in Figure 6 and Figure 8, is returned in the freezing cold air of freezing chamber 18 Mouth 64 is provided with freezer damper 68, therefore, can be supplied by the open and close control of freezer damper 68 to freezing chamber 18 cold The amount of gas.Therefore, although can prevent freezing chamber 18 from having become for set temperature, the temperature of refrigerating chamber 14 is high and compressor 27 It is driven with cooling fan 25, cold air is supplied to freezing chamber 18 and leads to sub-cooled, can be realized good freezen protective.

In the freezer 90 of present embodiment, especially freezer damper 68 is not provided with the cold air in freezing chamber 18 and blows Therefore 64 side of freezing cold air return port for exporting 63 sides but being set to 18 lower part of freezing chamber can simplify the structure in realization While, stable air door movement is obtained, the temperature control precision of freezing chamber 18 is can be improved and improves reliability.

That is, freezing chamber 18 close to cooling chamber 23 front surface and (referring to Fig. 6) is set, be set to the top of freezing chamber 18 Cold air blow-off outlet 63 is connected to (referring to Fig. 5) with 25 downstream side of cooling fan of cooling chamber 23.In such a structure, cooler When 24 defrosting operating, the high humidity after defrosting warms up cold air and is risen by its flowing in cooling chamber 23 and reach cold air blow-off outlet 63.If 63 side of cold air blow-off outlet be arranged freezer damper 68, the warm cold air contact refrigeration room air door 68 of high temperature and humidity and tie Dew, may freeze when cooling operating restarting after defrosting operating and initiation movement is bad.The icing in order to prevent needs To be arranged to freeze in freezer damper 68 and prevent dedicated heater, cause structure is complicated to change.

But by the way that freezer damper 68 is set to 23 lower part of cooling chamber the freezer 90 such as present embodiment Freeze cold air return port 64, generated high humidity was warmed up cold air and returned by flowing than freezing cold air with its major part when defrosting Place generates mouth 64 against the top and original sample rises, and therefore, touches the warm cold air minute quantity of freezer damper 68 and humidity is low, condense And then the case where icing of initiation, is slight.Therefore, the movement of freezer damper 68 can steadily be carried out.Moreover, in this implementation In the freezer 90 of mode, icing can be prevented by waste heat caused by the Glass tube heater 26 for defrosting.Root According to such structure, the ground such as dedicated heater that can not need to defrost make to simplify the structure.In other words, temperature can improved Reliability is improved while controlling precision.

In addition, freezer damper 68 as shown in Figure 11 and Figure 24 etc., is constituted by combining multiple pendulums 71, therefore, with The front and rear width size for the air door being made of a pendulum is compared, and front and back when multiple pendulums 71 are opened respectively can be substantially reduced Width dimensions.Therefore, setting freezer damper 68 can substantially be reduced while making itself densification of freezer damper 68 Space can make the volume in freezing chamber 18 increase corresponding amount.

In addition, as shown in figure 31b, multiple pendulums 71 of freezer damper 68 are respectively set to open to 23 side of cooling chamber. According to this structure, the volume in freezing chamber 18 can also be increased.That is, when freezer damper 68 with multiple pendulums 71 respectively to When the mode that 18 side of freezing chamber is opened is constituted, multiple pendulums 71 are respectively become to 18 side of freezing chamber form outstanding, if it has to Freezing chamber container 62 is set to forwards close to the position measured accordingly, so that the appearance for reducing freezing chamber container 62 of having to The volume of product, in other words freezing chamber 18.But structure as freezer 90 according to the present embodiment, it is able to solve in this way The problem of, the volume of freezing chamber 18 can be increased.

In addition, as shown in figure 29, being mounted with the cooling chamber side port frame portion of the freezing cold air return port 64 of freezer damper 68 66 to be more then located rear by top relative to vertical line, i.e. the mode of 23 side of cooling chamber tilts, that is, is installed on cooling chamber side port The end of 23 side of cooling chamber of the freezer damper 68 of frame portion 66 by be located at than 18 side of freezing chamber end on the lower in a manner of incline Tiltedly it is arranged.According to this structure, even if occurring as being generated in cooling chamber 23 when touching the defrosting operating of cooler 24 Warm cold air and such situation that condenses, dew can be also discharged by discharge outlet 36 to outside under 23 effluent of cooling chamber.Cause This, can prevent dew to being frozen under 18 effluent of freezing chamber in freezing chamber 18 and form ice cube so that causing failure.

In addition, being typically configured to when defrosting operating, freezer damper 68 is closed, and the warm cold air in cooling chamber 23 can not be into Enter in freezing chamber 18.

In addition, freezer damper 68 is as shown in figures 24 and 25,26 proximity of Glass tube heater with 23 lower part of cooling chamber Ground setting, therefore, when defrosting operating, temperature rises.But air door framework 70 and the multiple pendulums of composition freezer damper 68 71 it is equal formed by the material of heat resistance, therefore, thermal deformation etc. can be prevented, can span length ensure good air door movement the phase and make With.

In particular, freezer damper 68 is arranged to its underpart (air door framework 70 in the freezer 90 of present embodiment Lower portion) positioned at the positive side of Glass tube heater 26 and positioned at the position more against the top than its, therefore, freezer damper 68 can be directly hot as radiant heat line bring is reduced from the isolated form of Glass tube heater 26 in corresponding amount It influences, is able to suppress temperature rising.On the other hand, though the moisture heated by Glass tube heater 26 it is less warm cold air it is certain It contacts with freezer damper 68 and in 68 frosting of freezer damper, also can certainly defrost to it, thus air door movement becomes It obtains well.

Further, at a distance from Glass tube heater 26 it is short, bearing freezer damper 68 lower part cooling chamber side port The following 66a of frame portion 66 have to the shape outstanding of cooling chamber 23 (than cooling chamber 23 bottom surface 23a to 26 side of Glass tube heater Shape outstanding) (referring to Figure 29).According to this structure, the radiation hot line from Glass tube heater 26 can be prevented direct The air door for being irradiated to freezer damper 68 is following, can prevent extreme temperature from rising.Moreover, cooling chamber side port frame portion 66 Following 66a is made of double wall, and the gap portion 66b of double wall, which has, faces the open shape of freezing chamber 18.According to such Structure, in addition to the cooling effect using the cold air in freezing chamber 18, additionally it is possible to prevent extreme heating, it can be ensured that good Air door movement.
