Therefore, slowly and its amount is the most less than the situation being respectively provided with cold air gateway for the cold air come in and gone out in vegetable compartment 8. Therefore, if the cold air in vegetable compartment 8 becomes the degree replacing dry measure, become major part and rest on the state in vegetable compartment 8.That is, Cold air in vegetable compartment 8 is maintained state as the high humility comprising the dampness evapotranspired from vegetable.Thus, with in vegetable compartment 8 Cold air circulate replaceable such situation in a large number and compare, it is possible to the dry deterioration of vegetable be greatly reduced, compared with prior art, Can be with the best state cooling preservation vegetable.

On the other hand, in the freezer 90 represented in present embodiment, as shown in figure 12, the vegetable compartment in vegetable compartment 8 is led to Bottom, road portion 50 and the part relative with vegetable cold air gateway 44 are provided with vegetable compartment fan 53.Vegetable compartment fan 53 is in cooling fortune When rotating in Zhuaning, in return path 38, the major part of flowing returns cold air and attracted to vegetables from vegetable cold air gateway 44 In dish room passage portion 50.From the blow-off outlet 54 of vegetable compartment fan 53 to the lower floor's vegetable storage casing 49a rear surface in vegetable compartment 8 Cool-air feed.

Here, in present embodiment, vegetable compartment fan 53 is with the state configuration offset with vegetable cold air gateway 44.Cause This, even if opening is one of vegetable cold air gateway 44, so the discrepancy of the cold air carried out via vegetable cold air gateway 44 is also Become smooth and easy, it is possible to attract input reliably.That is, as shown in X, Y of Figure 12, connect at the central shaft with vegetable compartment fan 53 The part (bottom in Figure 12) on lower side of near vegetable cold air gateway 44, in as shown in X, cold air flows into vegetable compartment 8.Another Aspect, in the top end portion (top in Figure 12) of the vegetable cold air gateway 44 of the central shaft away from vegetable compartment fan 53, As shown in Y, cold air is clearly to be distinguished in the way of vegetable compartment 8 outflow.Therefore, even a vegetable cold air gateway 44, also The chaotic cold air that comes in and goes out being prevented from cold air is stagnated and result causes the not enough situation of cold air input.I.e., it is possible to return path Input cold air is attracted more reliably in 38, and from the blow-off outlet 54 of vegetable compartment fan 53 to cool-air feed in vegetable compartment 8.

And, even if in this case, cold air gateway is only one, thus with the situation being respectively provided with cold air gateway Comparing, in vegetable compartment, the replacement amount of cold air is less, is kept into high humility state by vegetable compartment 8, and maintains the dry bad of vegetable Change preventing effectiveness.

As it has been described above, in input vegetable compartment 8 and be supplied to the cold air of vegetable storage casing 48 of vegetable compartment 8, ratio is vegetable Only pass through in the space between space and vegetable storage casing 48 and internal perisporium between storage casing 48 and the bottom surface of vegetable compartment 8 Flowing when the air-supply pressure of cooling fan 19 is circulated is flowed quickly.And, as it has been described above, cold air comes in and goes out from vegetable cold air Mouth 44 carries out returning circulation to cooling chamber 16 via return path 38.Now, to cooling chamber 16 carry out return circulation cold air with Outer cold air attracted to from the first vegetable cold air sucting inlet 47 and the second vegetable cold air sucting inlet 51 being located at vegetable compartment 8 top First path 47a and alternate path 51a, and inhaled by vegetable compartment fan 53 via the vegetable compartment passage portion 50 with these communication Draw.The cold air attracted by vegetable compartment fan 53 via vegetable compartment passage portion 50 from the blow-off outlet 54 of vegetable compartment fan 53 again to vegetables Vegetable storage casing 48 in dish room 8 supplies, in vegetable compartment 8 internal diffusion and circulation.

Then, the condensation to vegetable compartment 8 prevents from illustrating.

Vegetable compartment 8 is subject to the cold spoke of the cooling chamber 16 from the back side being positioned at vegetable compartment 8 and the refrigerating chamber 9 being positioned at lower section Penetrate.As a result of which it is, as prior art, be prone to low temperature near the lower backside of vegetable compartment 8.Especially from cooling chamber 16 Cold emission stronger.Vegetable compartment 8 back side is in the part relative with the cooling chamber temperature field from cooling chamber 16 to cold room air door 31 By stronger cold emission, this part is prone to low temperature.This is because, cooling chamber 16 itself is cooling chamber temperature field certainly, and And also become identical with cooling chamber 16 extremely low from cooling chamber cold air transport road 30 region of cooling chamber 16 to cold room air door 31 The cooling chamber temperature field in temperate zone.

The low temperature near vegetable compartment lower backside that this cold emission brings, neutralizes appointing during cooling stops in cooling operating In the case of He, all the cold air in vegetable compartment 8 can be made to spread by utilizing the driving of vegetable compartment fan 53 and circulation eliminates. That is, when vegetable compartment fan 53 drives, the cold air in vegetable compartment 8 is diffused and circulates, by this diffusion and the cold air of circulation, Temperature is disperseed, and low temperature is suppressed.More specifically, utilize vegetable compartment fan 53 in vegetable compartment 8 internal diffusion and circulation Cold air, make because of from be positioned at vegetable compartment 8 back side cooling chamber temperature field cold emission and from the freezing being positioned at below vegetable compartment 8 The cold emission of room 9 and be prone to the temperature near the vegetable compartment lower backside of low temperature at vegetable compartment 8 internal diffusion.That is, vegetable is passed through Room fan 53 at vegetable compartment 8 internal diffusion and the cold air of circulation, reduce the temperature in vegetable compartment 8 and to cooling down in vegetable compartment 8, Suppress to produce extreme low temperature and temperature difference simultaneously near vegetable compartment lower backside, prevent condensation from producing.

Additionally, when all of room is less than design temperature, when the action of compressor 15 and cooling fan 19 stops, eliminating due to The pressure differential that the action of cooling fan 19 produces, all of cold air starts to based on the density contrast produced due to temperature difference Poised state flows.In this case, after cooling chamber cold air transport road 30, the pressure in refrigerating chamber 9 is higher, so cooling Cold air in room cold air transport road 30, cooling chamber 16 and refrigerating chamber 9 continues diffusion, until eliminating pressure differential.Now, refrigerating chamber 9 In and cooling chamber 16 in cold air accumulate in relatively low temperature and density that these are indoor higher, so at least cooling chamber cold air conveying Colder cold air in road 30 flows down downwards, and cold air arrives the height of the coldest cooling chamber 16.Here, cooling chamber 16 He Be full of colder cold air in refrigerating chamber 9, thus the above-mentioned colder cold air flow down via cooling chamber 16 and refrigerating chamber 9 to even The return path 38 of the cold air connect spreads.And, the cold air being diffused into return path 38 countercurrently arrives in return path 38 Lodge in the upper end of the cold air of cooling chamber 16, i.e. at the lower end height cooling down fan 19 of cooling chamber 16 upper opening.

In present embodiment, the lower end of vegetable cold air gateway 44 arranges than the loudspeaker lower end height cooling down fan 19 Height, it is possible to the cold air of suppression adverse current is flowed into vegetable compartment 8 from vegetable cold air gateway 44.Thus, suppression vegetable compartment 8 due to Countercurrently cold air and Local cooling, and be prevented from the condensation in vegetable compartment 8 and freeze, supercool, it is possible to prevent from preserving vegetable Deterioration.

As it has been described above, cooling operating neutralize cooling stop in any in the case of, be all prevented from the local of vegetable compartment 8 The condensation that causes of low temperature produce, even so the cooler 18 that cold air generates maximizes and cooling chamber 16 is across refrigerating chamber 9 and the large-scale freezer of big ability of vegetable compartment 8, it is also possible to suppress the condensation caused from the cold emission of cooling chamber 16.Therefore, In the freezer of the gamut of the large-scale freezer from the small-sized cooling storehouse of little ability to big ability, it is possible to suppress owing to coming The vegetable deterioration caused from the dew of the cold emission generation of cooling chamber 16, and with good state cooling preservation vegetable.And, Vegetable compartment 8 is located between cold room 7 and refrigerating chamber 9 " middle vegetable compartment type " by this freezer, it is possible to prevent Condensation produces and vegetable cooling preservation becomes good state, improves the use carrying out using centered by the access of vegetable etc. simultaneously The ease for use at family is effective.

Hereinafter, the action of freezer 290, the effect constituted like that above is described.

First, the action to kind of refrigeration cycle illustrates.

According to the temperature set in freezer 290, by the signal from control portion 269, kind of refrigeration cycle carries out action, and Carry out cooling operating.Condenser (not shown) is utilized to carry out certain degree from the cold-producing medium of the High Temperature High Pressure of compressor 215 discharge Condensation liquefaction.And, cold-producing medium is via the front surface shop front of the side or the back side and freezer 290 that are configured at freezer 290 Refrigerant piping (not shown) etc. prevents the condensation of freezer 290, and carries out condensation liquefaction, and arrives capillary tube and (do not scheme Show).Afterwards, cold-producing medium carries out heat exchange with the suction tube (not shown) to compressor 215 in capillary tube, and subtracts Pressure, becomes the liquid refrigerant of low-temp low-pressure and arrives cooler 218.The cold-producing medium supplied to cooler 218 is evaporated Gasification, generates the cold air for cooling down each storeroom in cooling chamber 216.

Then, the cooling action of circulating cold air is described.

The cold air of the low temperature generated in cooling chamber 216 utilizes cooling fan 219 to send from cooling chamber cold air transport road 230 To cold room 207 and refrigerating chamber 209.Supply after cold room 207 being cooled down to the cold air of cold room 207, this return cold air A part supply to vegetable compartment 208, each room is cooled to design temperature.And, cool the cold air behind each room and again return Return cooling chamber 216, and cooled down by cooler 218, utilize cooling fan 219 to circulate to each room.It addition, control portion 269 base In the detection temperature of temperature of refrigerating chamber test section 265 and freezer temperature test section 267, make compressor 215 and cooling fan 219 At least one in operating and stopping, thus carries out the cold air supply to each room.It addition, control portion 269 is to cold room wind Door 231, refrigerating chamber air door 234 carry out open and close controlling, and each room is maintained design temperature territory.

Then, the cooling action of vegetable compartment 208 is described.

Cold room cooling after cold air as shown in Figure 61, from the vegetable cold air gateway of the return path 238 being located at cold air 244 are supplied to, and vegetable compartment 208 are cooled down.Be located at the opening of vegetable compartment 208 and be only one of vegetable cold air gateway 244, institute for The cold air given to vegetable compartment 208 is circulated as described below.Cooling fan 219 operating in, i.e. cooling operating in, by by Pressure differential between vegetable compartment 208 and return path 238 that the air-supply of cooling fan 219 produces, cold air flows slowly into vegetable compartment 208, to replace a part for the cold air in vegetable compartment.And, cold air is in the inner circumferential of vegetable storage casing 248 with vegetable compartment 208 Flow in space between wall, and indirectly cool down the vegetable and plastics being accommodated in vegetable storage casing 248 from casing periphery Bottle etc., and flow out to return path 238 from vegetable cold air gateway 244.And, cold air from cold air returning pipe road 240 to cooling Room 216 is circulated.

Therefore, the cold air come in and gone out in vegetable compartment 208 than be respectively provided with the situation of cold air gateway slowly and its amount the most relatively Few.Therefore, if the cold air in vegetable compartment 208 becomes the degree replacing dry measure, become major part and rest on the shape in vegetable compartment 208 State.That is, state as the cold air in vegetable compartment 208 is maintained the high humility comprising the dampness evapotranspired from vegetable.Thus, with vegetables Cold air in dish room 208 circulates replaceable such situation in a large number to be compared, it is possible to the dry deterioration of vegetable is greatly reduced, with existing Technology is compared, it is possible to the best state cooling preservation vegetable.

On the other hand, in the freezer 290 represented in present embodiment, as shown in Figure 61, in the vegetable compartment of vegetable compartment 208 Passage portion 250 bottom and the part relative with vegetable cold air gateway 244 are provided with vegetable compartment fan 253.Vegetable compartment fan 253 exists When rotating in cooling operating, in return path 238, the major part of flowing returns cold air from vegetable cold air gateway 244 quilt It is attracted in vegetable compartment passage portion 250.From the blow-off outlet 254 of vegetable compartment fan 253 to the lower floor's vegetable storage in vegetable compartment 208 Casing 249a rear surface cool-air feed.

Here, in present embodiment, vegetable compartment fan 253 is with the state configuration offset with vegetable cold air gateway 244.Cause This, is even if opening is one of vegetable cold air gateway 244, so the discrepancy of the cold air carried out via vegetable cold air gateway 244 Also ratio is become smoothly, it is possible to attract input reliably.That is, as shown in X, Y of Figure 61, with vegetable compartment fan 253 The part (bottom in Figure 61) on lower side of the vegetable cold air gateway 244 that central shaft is close, as shown in X, cold air flows into vegetable compartment In 208.On the other hand, at the top end portion (figure of the vegetable cold air gateway 244 of the central shaft away from vegetable compartment fan 253 Top in 61), as shown in Y, cold air is clearly to be distinguished in the way of vegetable compartment 208 outflow.Therefore, even a vegetable Cold air gateway 244, it is also possible to prevent the chaotic cold air that comes in and goes out of cold air to stagnate and result causes the not enough situation of cold air input. I.e., it is possible in return path 238, attract input cold air more reliably, and from the blow-off outlet 254 of vegetable compartment fan 253 to vegetable Cool-air feed in room 208.

And, even if in this case, cold air gateway is only one, thus with the situation being respectively provided with cold air gateway Comparing, in vegetable compartment, the replacement amount of cold air is less, will be kept into high humility state, and maintain being dried of vegetable in vegetable compartment 208 Deterioration preventing effect.

As it has been described above, in input vegetable compartment 208 and be supplied to the cold air of vegetable storage casing 248 of vegetable compartment 208, than The space between space and vegetable storage casing 248 and internal perisporium between vegetable storage casing 248 and the bottom surface of vegetable compartment 208 Flowing when being the most only circulated by the air-supply pressure of cooling fan 219 is flowed quickly.And, as it has been described above, cold air is from vegetables Dish cold air gateway 244 carries out returning circulation to cooling chamber 216 via return path 238.Now, return to cooling chamber 216 Return the cold air beyond the cold air of circulation cold from the first vegetable cold air sucting inlet 247 and the second vegetable being located at vegetable compartment 208 top Aspiration entrance 251 attracted to the first path 247a and alternate path 251a, and leads to via the vegetable compartment with these communication Road portion 250 is attracted by vegetable compartment fan 253.The cold air attracted by vegetable compartment fan 53 via vegetable compartment passage portion 250 is from vegetable The blow-off outlet 254 of room fan 253 vegetable in vegetable compartment 208 again storage casing 248 supplies, at vegetable compartment 208 internal diffusion And circulation.

Then, the condensation to vegetable compartment 208 prevents from illustrating.

Vegetable compartment 208 is subject to the cooling chamber 216 from the back side being positioned at vegetable compartment 208 and the refrigerating chamber 209 being positioned at lower section Cold emission.As a result of which it is, as prior art, be prone to low temperature near the lower backside of vegetable compartment 208.Especially from The cold emission of cooling chamber 216 is stronger.Vegetable compartment 208 back side with the cooling chamber temperature from cooling chamber 216 to cold room air door 231 The relative part in territory is by stronger cold emission, and this part is prone to low temperature.This is because, cooling chamber 216 itself is cold certainly But room temperature territory, and also become with cold from cooling chamber cold air transport road 230 region of cooling chamber 216 to cold room air door 231 But the cooling chamber temperature field in the extremely low temperate zone that room 216 is identical.The low temperature near vegetable compartment lower backside that this cold emission brings, Cooling operating neutralize cooling stop in any in the case of, all can make vegetable by utilizing the driving of vegetable compartment fan 253 Cold air diffusion and circulation in room 208 eliminate.That is, when vegetable compartment fan 253 drives, the cold air in vegetable compartment 208 is carried out Diffusion and circulation, by this diffusion and the cold air of circulation, temperature is disperseed, and the low temperature of local is suppressed.More specifically, Utilize vegetable compartment fan 253 at vegetable compartment 208 internal diffusion and the cold air of circulation, make because of from being positioned at the cold of vegetable compartment 208 back side But the cold emission in room temperature territory and be prone to the vegetable compartment of low temperature from the cold emission of the refrigerating chamber 209 being positioned at below vegetable compartment Temperature near lower backside is at vegetable compartment 208 internal diffusion.That is, and followed at vegetable compartment 208 internal diffusion by vegetable compartment fan 253 The cold air of ring, reduces the temperature in vegetable compartment 208 and to cooling down in vegetable compartment 208, suppresses under the vegetable compartment back side simultaneously Produce extreme low temperature and temperature difference near portion, prevent condensation from producing.

Additionally, when all of room is less than design temperature, when the action of compressor 215 and cooling fan 219 stops, eliminating by In the pressure differential that the action of cooling fan 219 produces, all of cold air starts to based on the density contrast produced due to temperature difference Poised state flowing.In this case, after cooling chamber cold air transport road 230, the pressure in refrigerating chamber 209 is higher, so Cold air in cooling chamber cold air transport road 230, cooling chamber 216 and refrigerating chamber 209 continues diffusion, until eliminating pressure differential.Now, Cold air in refrigerating chamber 209 and in cooling chamber 216 accumulates in these indoor higher with relatively low temperature and density, thus the coldest But the colder cold air in room cold air transport road 230 flows down downwards, and cold air arrives the height of the coldest cooling chamber 216.? This, be full of colder cold air, so the above-mentioned colder cold air flow down is via cold in cooling chamber 216 and refrigerating chamber 209 But room 216 and refrigerating chamber 209 spread to the return path 238 of the cold air connected.And, it is diffused into the cold air of return path 238 Adverse current in, return path 238 and arrive the upper end of the cold air lodging in cooling chamber 216, i.e. at cooling chamber 216 upper opening The lower end height of cooling fan 219.

In present embodiment, the lower end of vegetable cold air gateway 244 arranges than the loudspeaker lower end height cooling down fan 219 Height, it is possible to the cold air of suppression adverse current is flowed into vegetable compartment 208 from vegetable cold air gateway 244.Thus, suppression vegetable compartment 208 due to adverse current cold air Local cooling, and be prevented from the condensation in vegetable compartment 208 and freeze, supercool, it is possible to prevent Preserve the deterioration of vegetable.

As it has been described above, cooling operating neutralize cooling stop in any in the case of, be all prevented from the office of vegetable compartment 208 The condensation that the low temperature in portion causes produces, even so the cooler 218 that cold air generates maximizes and cooling chamber 216 is across cold Freeze the large-scale freezer of the big ability of room 209 and vegetable compartment 208, it is also possible to suppress to cause from the cold emission of cooling chamber 216 Condensation.Therefore, in the freezer of the gamut of the large-scale freezer from the small-sized cooling storehouse of little ability to big ability, it is possible to Suppress the vegetable deterioration caused due to the dew produced from the cold emission of cooling chamber 216, and protect with good state cooling Deposit vegetable.And, vegetable compartment 208 is located at " middle vegetable compartment between cold room 207 and refrigerating chamber 209 by this freezer Type ", it is possible to prevent condensation from producing and vegetable cooling preservation becomes good state, improve the access with vegetable etc. simultaneously Centered by the ease for use of user that carries out using be effective.

Then, the cooling of vegetable compartment 208 and condensation prevent from controlling to use Figure 71～Figure 75 to illustrate.

Figure 71 is the flow chart of the vegetable compartment cooling action of the freezer that embodiment 5 is described.Figure 72 is to represent by cold Gas circulates the sequential chart of action when making same vegetable compartment samming.Figure 73 is to represent to make same vegetable compartment samming by circulating cold air The sequential chart of cooling action when simultaneously cooling down.Figure 74 is to represent the passing through when temperature of same vegetable compartment is higher than set point of temperature The samming of circulating cold air and the sequential chart of cooling action.Figure 75 is the flow process of the actual cooling condition example representing same vegetable compartment Figure.

As shown in the flow chart of Figure 71, the freezer 290 of present embodiment, as common freezer, is primarily based on cold That hides that the temperature of room 207 or refrigerating chamber 209 determines cooling operating could (S1).That is, compressor 215 and cooling fan 219 are determined Could operate.Such as when the temperature of refrigerating chamber 209 is more than design temperature, based on from freezer temperature test section 267 Output, control portion 269 drives compressor 215 and cooling fan 219 to drive.And control portion 269 opens refrigerating chamber air door 234, cold Hide room air door 231 and partial freeze room air door is (following, for the purpose of simplifying the description, to control the cold of the cold air supply to vegetable compartment 208 Illustrate as a example by hiding room air door 231).As a result of which it is, the cool-air feed generated by cooler 218 is to refrigerating chamber 209, cold room 207 etc., it is fed simultaneously to vegetable compartment 208, and cold room 207, vegetable compartment 208 and refrigerating chamber 209 are cooled down.Now, as Upper described, vegetable compartment 208 is inputted by the cold air that the air-supply of cooling fan 219 brings and stably cools down.

Then, after cooling operating can negate (S1), input external air temperature also judges external air temperature state (S2).Based on the temperature results judged, revise the initial vegetable compartment fan 253 set driving time (connect driving time and Shut-in time), and it is set as timer driving time (S3).Such as, with at external air temperature as set point of temperature more than summer It etc. extend the fans drive time, set timer shortening the mode of fans drive time for winter below set point of temperature etc. Driving time.

Then, input vegetable compartment temperature be whether cooling temperature range when stablizing to this temperature, i.e. it is pre-designed certainly Carry out in the range of fixed set point of temperature judging (S4), in the range of set point of temperature, be then clocked into device and control operating (S5).

On the other hand, if above-mentioned steps (S4) is judged to vegetable compartment temperature be more than set point of temperature scope, such as by Temperature when temperature uprises such transition in the access of vegetable etc., then enter temperature and control operating (S6).

Above-mentioned steps (S4) is judged to temperature when vegetable compartment temperature is below set point of temperature scope, in vegetable compartment 208 Fully step-down, vegetable compartment fan 253 is set to halted state (S14) by control portion 269.Thereby, it is possible to suppression is along with vegetable compartment wind The power consumption of fan 253 rotation, it is achieved the good cooling preservation of vegetable.

Then, illustrate that timer controls operating (S5).

When being clocked into device and controlling operating (S5), first confirm that whether be in cooling operating, i.e. compressor 215 and cooling Whether fan 219 is in operating (S8).

If not in operating, then vegetable compartment fan 253 is set to halted state (S14).Thus, regardless of freezer 290 Operating stops, and vegetable compartment fan 253 all rotates, by hearing this sound, it is possible to prevent from bringing distrust to user.

If in Yun Zhuan, the most then confirm whether cold room air door 231 is opened, i.e. whether cold room air door 231 is opened, Whether the cool-air feed from cooling chamber 216 is cooled down (S9) to cold room 207 and vegetable compartment 208 to these each rooms.

If closing cold room air door 231, and when stopping the cooling of cold room 207 and vegetable compartment 208, then based on timing Device driving time carries out sammingization operating (S10) for preventing vegetable compartment from condensing.Carry out when closing cold room air door 231 In sammingization operating, cold air does not flow to return path 238, so by the rotation of vegetable compartment fan 253, in making vegetable compartment 208 Cold air circulate in vegetable compartment 208, eliminate the temperature difference in vegetable compartment and suppress condensation to produce.

Additionally, although it is not shown, above-mentioned samming operates at temperature of refrigerating chamber and vegetable compartment temperature is the most relatively low and continuous More than certain time and be not switched on during cold room air door 231 all carrying out, drive vegetable compartment fan based on timer driving time 253, prevent condensation from producing.That is, control portion 269 is when the operating stopping of the compressor that cold air generates is in certain time, will Vegetable compartment fan 253 is forcibly set to halted state.Halted state continuation certain time when the compressor that cold air generates Time above, control operating based on timer and drive vegetable compartment fan 253.

Here, sammingization operating makes vegetable compartment fan 253 carry out Spin Control with the time predetermined, so always examining Survey the temperature in vegetable compartment 208, it is possible to reduce the temperature detection that can produce when vegetable compartment fan 253 is carried out Spin Control and postpone The temperature control deviation caused.Thereby, it is possible to make the temperature stabilization in vegetable compartment 208 and with good state cooling preservation vegetables Dish.

It addition, the driving of vegetable compartment fan 253 when timer controls sammingization operating (S10) in operating (S5) is to enter The mode of the time considering external air temperature in row step (S3) and set controls, even if so be subject to from door side etc. from The thermal change of extraneous air, it is also possible to make the cold air in vegetable compartment fully circulate according to this change.Thereby, it is possible to make vegetable compartment Interior temperature reliably carries out samming, it is possible to reliably and efficiently suppress the condensation produced due to the temperature difference in vegetable compartment.

Figure 72 represents the driving condition of vegetable compartment fan 253 when timer controls the samming that operating carries out and vegetable compartment The state of temperature of 208.When compressor 215 carries out operating and cold room air door 231 is closed, vegetable compartment fan 253 rotates.By This, the temperature in vegetable compartment 208 will not produce the deviation that temperature detection delay etc. causes, and samming is melted into the most certain temperature Degree.Thereby, it is possible to be reliably suppressed the condensation produced due to the temperature difference in vegetable compartment 208.Additionally, the A in Figure 72 represents meter Time device control operating the samming duration of runs.

On the other hand, the result that the operating condition in step (S8) confirms, if cold room air door 231 is opened and to vegetables During dish room 208 etc. cools down, then vegetable compartment fan 253 is carried out the driving for above-mentioned samming, and also carry out for The driving of cooling, and carry out cooling+sammingization operating (S12) of vegetable compartment 208.This cooling+sammingization operating is as it has been described above, lead to Cross the rotation of vegetable compartment fan 253, attract to be taken into by the cold air of flowing in return path 238 energetically, and with in vegetable compartment Initially the cold air of circulation circulates together in vegetable compartment 208, and to carrying out samming in vegetable compartment 208, suppression condensation produces, and In cooling vegetable compartment 208.

Figure 73 represents the driving condition of vegetable compartment fan 253 when timer controls cooling+samming that operating carries out.Cold But with rotating and the sammingization the most predetermined certain timer driving time (S13a) of rotation.Thus, by vegetable In the range of in room 208, cooling maintains set point of temperature, and in vegetable compartment, cold air cycles as mentioned above, and prevents from producing in vegetable compartment Raw bigger temperature difference also suppresses condensation to produce.Additionally, the B in Figure 73 represents when timer controls the cooling operating in operating Between.

Here, the driving of vegetable compartment fan 253 when timer controls the cooling+sammingization operating (S12) in operating (S5) The dynamic time (S13a) carrying out consideration external air temperature in step (S3) and set.Therefore, when operating with sammingization as, energy The radiations heat energy from extraneous air that enough bases are subject to from door side etc., makes the cold air in vegetable compartment fully circulate, and can Input is suitable to the cold air of the amount of vegetable indoor temperature.Thereby, it is possible to by vegetable indoor temperature reliably samming reliable and high Prevent the condensation caused by temperature difference from producing to effect.And then, vegetable compartment 208 will not be made interior by about external air temperature, it is possible to In the range of reliably cooling maintains set point of temperature.And, the rotation of vegetable compartment fan 253 is to control by timer further The time Spin Control that operating determines, so always detecting the temperature in vegetable compartment 208, it is possible to reduce vegetable compartment fan 253 The temperature detection that can produce when carrying out Spin Control postpones the temperature control deviation caused.As mentioned above, it is possible to make vegetable compartment 208 Interior temperature stabilization, and with good state cooling preservation vegetable.

Then, illustrate that temperature controls operating (S6).

When entering (S6) when temperature controls operating, first revise further in step (S3) according to the temperature of vegetable compartment 208 Cooling timer driving time in the timer driving time set, and it is set as that the cooling temperature-driven time sets (S7)。

Afterwards, control with timer as operating (S5), in being confirmed whether to operate for cooling, i.e. compressor 215 and cooling Whether fan 219 is in operating (S8).

In this case, the judgement of the vegetable compartment temperature in step (S4) is more than set point of temperature scope, so compressor 215 and cooling fan 219 certainly for operating in.And, it is confirmed whether to open cold room air door 231, the most whether opens cold room These each rooms are cooled down by air door 231 by the cool-air feed from cooling chamber 216 to cold room 207 and vegetable compartment 208 (S9).In this case, the judgement of the vegetable compartment temperature in step (S4) is more than set point of temperature scope, so compressor 215 and cooling fan 219 in operating, and during cold room air door 231 is opened but is cooled down.Therefore, vegetable compartment fan is driven 253, carry out cooling+sammingization operating (S12) of vegetable compartment 208.

Here, temperature controls the driving base of the vegetable compartment fan 253 of the cooling in operating (S6)+sammingization operating (S12) In step (S7), the cooling temperature-driven time based on vegetable compartment temperature adjustmemt is carried out, when through supercooling temperature-driven Between time (S13b) stop (S14).That is, when the access due to vegetable etc. is by open for vegetable compartment, thus, extraneous air entrance etc. and warm When degree uprises, vegetable compartment fan 253 rotates the cooling temperature-driven time set based on the temperature in vegetable compartment 208 and stops Only.Therefore, it is possible to set point of temperature reliably and quickly will be cooled in vegetable compartment, and carry out the samming of vegetable indoor temperature, It is also prevented from condensation to produce.

Figure 74 represents the driving condition of the vegetable compartment fan 253 being controlled operating (S6) by temperature.It is applied not only to vegetable compartment The samming time of the samming in 208, and the cool time of cooling in vegetable compartment carried out is according to vegetable compartment 208 Temperature is the most elongated, and vegetable compartment fan 253 carried out rotating (S13b) with the time being most suitable for the temperature of vegetable compartment 208.Thus, input The amount of the cold air in vegetable compartment 208 increases, it is possible to reliably and quickly cool down in vegetable compartment 208, and can be by vegetable compartment In 208 samming and prevent condensation produce.In this case, if the driving time extending vegetable compartment fan 253 improves simultaneously Rotating speed, or only improve rotating speed etc., then can increase the amount of the cold air inputted in vegetable compartment 208, by vegetable compartment in shorter time 208 are cooled to set point of temperature.Additionally, the C in Figure 74 represents that temperature controls the cooling duration of runs in operating.

Figure 75 is an example of the cooling condition representing the vegetable compartment 208 when being controlled by the control of present embodiment 5 Sequential chart.As shown in Figure 75, when the temperature in vegetable compartment 208 is in the range of equilibrium temperature state i.e. set point of temperature (X), for Cooling and samming, control the duration of runs by the timer determined in vegetable compartment fan 253 actuation step (S3).That is, vegetable During room proper temperature stable, vegetable compartment 208 cools down with cooling operating 1 (timer control).In order to take out such as vegetable Deng, during the transition that in opening vegetable compartment 208 and becoming vegetable compartment 208, temperature uprises time (Y), according to the temperature in vegetable compartment, drive The cool time of dynamic vegetable compartment fan 253 is elongated, efficiently cooling vegetable compartment 208.Here, to cooling operating 1 (timer control System) add cooling operating 2 (temperature control), cooling extends the duration of runs.And, along with in vegetable compartment 208, temperature reduces, drive The cool time of vegetable compartment fan 253 shortens.When the temperature of vegetable compartment 208 arrives below set point of temperature, terminate cooling operating 2 (temperature control).

And, in the range of the set point of temperature when temperature in vegetable compartment 208 is back to stable time (X), revert to step (S3) timer determined in controls the duration of runs, carries out the cooling in vegetable compartment and samming.That is, become when vegetable compartment 208 During proper temperature, revert to only cool down the operating of operating 1 (timer control).

(embodiment 6)

Figure 76 is the axonometric chart of the cold air flow of the cooling chamber back portion of the freezer that embodiment 6 is described.Figure 77 is The summary sectional view of the cold air flow in the vegetable compartment that the freezer of this embodiment 6 is described.

The freezer 290 of present embodiment is respectively provided with each vegetable cold air inlet 245 and vegetable cold air return port 246 Replace the vegetable cold air gateway 244 of explanation in embodiment 5.That is, vegetable compartment 208 is provided with vegetable cold air inlet 245, Further than vegetable cold air inlet 245 position by the top, such as the first path 247a, alternate path 251a and vegetable compartment path Vegetable cold air return port 246 it is provided with near the interflow in portion 250.

Other structure, comprise control all as embodiment 5, to identical element mark identical symbol omitting Explanation.

In present embodiment 6, the cold air in the return path 238 of cold air flows into from vegetable cold air inlet 245, vegetable compartment Cold air in 208 flows out to the return path 238 of cold air from vegetable cold air return port 246.Therefore, cold from a vegetable with cold air The situation that gas gateway 244 comes in and goes out is compared, and the discrepancy of cold air is smooth and easy, and more cold air flows in vegetable compartment 208.Thus, efficiently Ground inputs cold air in vegetable compartment, it is possible to strongly in cooling vegetable compartment 208.Thus, it is in freezer in such as vegetable compartment 208 The foot of main body, and the bottom of vegetable compartment 208 is not easily susceptible to the heat radiation from extraneous air and the cold preservation of low temperature type Storehouse etc. are effective.

For other action effect, suppress vegetables except utilizing a vegetable cold air gateway 244 to make cold air come in and go out Beyond the effect of the dry deterioration of dish, as embodiment 5, and omit the description.

As it has been described above, the freezer 290 of embodiment 5,6 is that vegetable compartment 208 is configured at cold room 207 and refrigerating chamber Structure between 209, not from cold room 207 and refrigerating chamber 209 to the caloric receptivity of vegetable compartment 208, so except repertory to Beyond during the replacement of vegetable compartment 208, vegetable compartment temperature stabilization.Therefore, if the temperature stabilization of vegetable compartment 208, i.e. vegetable room temperature When degree is in the range of set point of temperature, the timer being driven vegetable compartment fan 253 controls to operate.On the other hand, vegetables Dish room temperature due to during the replacement of repertory etc. and rapid increase, vegetable compartment temperature becomes the temperature higher than set point of temperature scope Time, the temperature being driven vegetable compartment fan 253 with the time set based on vegetable compartment temperature controls operating.Thereby, it is possible to it is real The most optimal vegetable compartment temperature controls.

The freezer 290 of embodiment 5,6 can suppress the condensation caused by temperature difference in vegetable compartment 208 to produce, with Time by vegetable compartment cooling be kept into low temperature, it is possible to always with good state cooling preservation vegetable.It addition, it is cold about vegetable compartment But, freezer 290 also has following effect.

First, vegetable compartment fan 253 makes the cold air lower floor vegetable storage casing 249a to vegetable storage casing 248 and upper strata The peripheral circulation of vegetable storage casing 249b.Thus, the cold air utilizing vegetable compartment fan 253 to circulate enters lower floor's vegetable storage casing In 249a and upper strata vegetable storage casing 249b, it is possible to suppression is flowed each other vegetable.As a result of which it is, can also prevent due to Cold air flows each other vegetable the dry deterioration of the vegetable that can produce, and with fresh and good state cooling preservation vegetable.

Freezer 290 is in the vegetable storage being made up of lower floor vegetable storage casing 249a and upper strata vegetable storage casing 249b The top of casing 248 is provided with the first vegetable cold air also become at vegetable compartment 208 internal diffusion or the suction inlet of the cold air of circulation and inhales Entrance 247 and the second vegetable cold air sucting inlet 251.Therefore, in vegetable compartment 208, the cold air of circulation will not enter by lower floor vegetable In the vegetable storage casing 248 that storage casing 249a and upper strata vegetable storage casing 249b is constituted, and flow directly into the first vegetable Cold air sucting inlet 247 and the second vegetable cold air sucting inlet 251.Thereby, it is possible to be reliably prevented the dry deterioration of vegetable and with newly Fresh and good state cooling preservation vegetable.By making the top-open edge of upper strata vegetable storage casing 249b close to becoming vegetable The demarcation strip 205 in ceiling canopy face, it is possible to improve the effect above further.Additionally, by arranging the upper opening of lid of covering, it is possible to More effectively improve the effect above.
