Summary of the invention

But, when utilizing refrigerated item (0 ℃～15 ℃ levels) such as refrigerated truck or the freezing product of reach in freezer combined shipment (20 ℃ of levels) and fresh food, because the temperature difference between Room 2 is big, so the storehouse inwall of will transmitting scriptures moves a large amount of heat from the chamber, storehouse of high temperature side to the chamber, storehouse of low temperature side.Its result may cause the chamber, storehouse of high temperature side too to be cooled off or deficiency is cooled off in the chamber, storehouse of low temperature side, has reduced the quality of goods.

At this moment, in order too to cool off the chamber, storehouse that prevents high temperature side, can be as patent documentation 1,2 be put down in writing, utilize the heating of the high temperature refrigerant of the cooling water of engine or refrigerator, but owing to need utilize pipe arrangement to connect refrigerator or engine and Ku Nei, so not only structure becomes complicated, but also there is the problem that is easy to take place because of the faults such as leakage of the improper cooling water that causes of piping engineering or refrigerant.In the unmanned transportation of reach in freezer, in when, for example when railway transportation such fault having taken place, owing to can not carry out alignment processing for a long time, so may lose commodity value.

In addition, if mixing year freezing product and refrigerated item, also mistakenly partition wall be fixed under the state of favorite places, carry out respectively each storehouse room temperature being controlled to the so-called two temperature bands control of cryogenic temperature and refrigerated storage temperature, then owing to do not distinguish internal tank by partition wall, so because of the cold air inflow integral container of cryogenic temperature causes refrigerated item also to be frozen, the result causes the commodity value forfeiture of refrigerated item.

On the other hand, because usually T shape track has adopted the extrusion molded article of the aluminium of high thermoconductivity on long-pending basis, heavy in section, thus can be when moving a large amount of heat by flooring material, by a large amount of heat that flows away of the cold air path based on its flooring material.Therefore, when cutting off for chamber, a plurality of storehouse in the storehouse by partition wall, though need to cooperate the cross sectional shape ground of flooring material to form partition wall, obstruction is based on the passage of the cold air of flooring material, but it is relatively more difficult to cooperate the cross sectional shape ground of flooring material to form partition wall by the cross sectional shape of inlet contraction, inner broad such flooring material, reliably the passage of airtight cold air.In addition, also there is the structure of the partition wall shortcoming that operation trouble and so on is set of complexity and partition wall that becomes.And, if even if the passage of airtight cold air based on flooring material can not avoid moving by the long-pending flooring material in heavy in section the situation of a large amount of heat.

In addition, in engine-driven lift-launch electric generator type refrigerator of the reach in freezer of patent documentation 5, when in container or truck, having carried refrigerator, need the size of design refrigerator to make it to have the ability that can be cooled to-20 ℃～-30 ℃ of degree.At this moment, if use the control of the so-called two temperature bands of different design temperature control freezers and freezer Room 2 as described above, the situation of heater of compressor and freezer side then will occur turning round simultaneously, and in the refrigerator of above-mentioned design, compressor and heater if turn round simultaneously then overload will appear in generator (engine) thereupon will go wrong aspect security.

In order to address this problem, though can carry the generator (engine) of the capacity that on the ability of compressor, has increased the ability that drives the heater degree, but then will cause generator to maximize if so, aspect weight, all there is unfavorable such problem in cost aspect, combustion expense aspect.

The present invention finishes in view of above-mentioned such problem points, and the 1st purpose provides and can reliably prevent to accommodate the storehouse temperature supercooling of refrigerated item to the reach in freezer below the refrigerated storage temperature with simple structure.

The 2nd purpose provides when cooperating car loading to be distinguished into the cup of any volume and chamber, back in container by partition wall, can suppress to accommodate the cup of freezing product as much as possible and accommodate the reach in freezer that moves of the heat between the back chamber of refrigerated item.

The 3rd purpose provides when cooperating car loading to be distinguished into the cup of any volume and chamber, back in container by partition wall, can suppress the leakage of heat as much as possible, reliably respectively control accommodate freezing product cup in cryogenic temperature with accommodate the back chamber of refrigerated item in the reach in freezer of refrigerated storage temperature.

The 4th purpose provides when partition wall is in favorite places, can stop to control the two temperature bands control of each chamber, storehouse in cryogenic temperature and refrigerated storage temperature respectively, prevents that reliably refrigerated item is cooled to the reach in freezer of cryogenic temperature mistakenly.

The 5th purpose drives when providing by avoidance compressor and heater, can under the ability of the refrigerator of above-mentioned design, also can avoid the generation of the overload of engine, safety and the cold insulation operation controller of reach in freezer that stably carries out the control of two temperature bands.

Reach in freezer of the present invention is by the antetheca that has thermal insulation respectively, roof, diapire, about sidewall and the freezing unit of the container that forms of rear wall and the antetheca outside that is arranged on container constitute, in the back chamber of cup that inner area is divided into the antetheca side by the partition wall that can move and rear wall side along the inner face of container, also respectively cup is set at low temperature side, back chamber is set at high temperature side, be when utilizing freezing unit cooling cup, the cold air of cup is imported the reach in freezer of chamber, cooling back, chamber, back, it is characterized in that: above-mentioned freezing unit is by prime mover, by the generator of prime mover driven with have and utilize the refrigerating plant of power-actuated motor compressor that generator sends to constitute, back chamber is provided with and prevents the supercooling electric heater.

Utilize the reach in freezer that constitutes like this, can when cup is written into goods (freezing product) and stationary partition, after the chamber, back has been written into goods (refrigerated item), make freezing unit work, cup is cooled to cryogenic temperature.Promptly when driving prime mover driven generator, the driven by power motor compressor that utilizes generator to send is cooled to cryogenic temperature at the air of the evaporimeter heat exchange cup of refrigerating plant.On the other hand, with chamber behind the cooled guide of cup, make the chamber, back be cooled to refrigerated storage temperature.Here, during to the refrigerated storage temperature that sets, utilized the electric power that sends by generator to make electric heater work by supercooling in the chamber, back, by heating the chamber, back, can prevent reliably the chamber, back be cooled to need temperature more than.

Perhaps, reach in freezer of the present invention is by the antetheca that has thermal insulation respectively, roof, diapire, about sidewall and the freezing unit of the container that forms of rear wall and the antetheca outside that is arranged on container constitute, in the back chamber of cup that inner area is divided into the antetheca side by the partition wall that can move and rear wall side along the inner face of container, also respectively cup is set at low temperature side, back chamber is set at high temperature side, be when utilizing freezing unit cooling cup, the cold air of cup is imported the reach in freezer of chamber, cooling back, chamber, back, it is characterized in that: when being formed flatly the surface of above-mentioned diapire, dispose a plurality of lath (pedals at diapire, curtain plate), between a pair of lath of adjacency, dispose partition wall.

As the diapire that has been formed flatly above-mentioned surface, though can enumerate plastic plates such as steel plate, FRP such as stainless steel, implement the timber of water-fast processing, if but considered durability, could adopt then suitably that pyroconductivity differs some materials than FRP or timber, as adopting stainless-steel sheet.

As above-mentioned lath, consider that from the viewpoint of durability or usability can require it is lightweight, high-intensity material.As the material that satisfies such requirement, can suitably adopt aluminium or FRP.And then, towards length direction ground configuration lath, can between the perpendicular lattice of adjacency, guarantee the passage of cold air by perpendicular lattice.

Utilize the reach in freezer that constitutes like this, after cup has been paved with lath, the goods of packing into (freezing product) stationary partition.If fixed partition wall, then in the back after the chamber has been paved with lath, the goods of packing into (refrigerated item).After this, make freezing unit work, cup is cooled to cryogenic temperature.That is, drive the compressor of refrigerating plant, be cooled to cryogenic temperature at the air of evaporimeter heat exchange cup.Simultaneously, the chamber, cold air importing back with cup is cooled to refrigerated storage temperature with the chamber, back.

At this moment, the cold air that is blown into the cold air of cup and is blown into the chamber, back circulates via lath, does not exist cold air to be detained.

Its result, the length that can separate lath be stationary partition at an arbitrary position at interval, cooperates car loading that the inner space of container is distinguished into cup and chamber, back.And, owing to be formed flatly the surface of diapire, thus can be in the structure of simplification partition wall, do not produce with gap between the positiver sealing partition wall and diapire.In addition, can make the sectional area of diapire become minimum, reduce the heat of the diapire of flowing through significantly.Thereby the cold air flow of relatively-high temperature of back chamber that can suppress to accommodate refrigerated item is to the cup of accommodating freezing product.

Perhaps, reach in freezer of the present invention is by the antetheca that has thermal insulation respectively, roof, diapire, about sidewall and the freezing unit of the container that forms of rear wall and the antetheca outside that is arranged on container constitute, in the back chamber of cup that inner area is divided into the antetheca side by the partition wall that can move and rear wall side along the inner face of container, also respectively cup is set at low temperature side, back chamber is set at high temperature side, be when utilizing freezing unit cooling cup, the cold air of cup is imported the reach in freezer of chamber, cooling back, chamber, back, it is characterized in that: above above-mentioned antetheca inner face, be provided with in the heat exchanger and fan of freezing unit, the width that spreads all over the roof inner face all sidedly an end opening near antetheca, other end opening is in the chamber, back, distinguished inner flat breather line about being provided with, in addition, rearward end at the roof inner face has front opening part and rear peristome, when inside is provided with cooling fan and circulating fan, the place ahead of also closing on circulating fan is provided with the mixing duct that has set electric heater, and then, when the antetheca inner face closes on heat exchanger and is arranged on the air duct that above-below direction extends, also the rear peristome that closes on mixing duct at the rear wall inner face is arranged on the air duct that above-below direction extends, in addition, also the back chamber side opening of one side about breather line is communicated in the front opening part of the cooling fan that closes on mixing duct, side face at above-mentioned partition wall is provided with encapsulant, makes it the diapire inner face that closely contact has formed tabular surface, the diapire outside of left and right sides side wall inner surface and breather line.

Utilize the reach in freezer that constitutes like this, when cup is packed goods (freezing product) and stationary partition into, after the chamber, back has been packed goods (refrigerated item) into, make freezing unit work, cup is cooled to cryogenic temperature.That is, drive the compressor of refrigerating plant, attract the air of the cup of coming in to make it to be cooled to cryogenic temperature in the heat exchange of heat exchanger place via fan.In addition, also drive circulating fan, make the air circulation of chamber, back.At this moment, in cup and chamber, back, the air of circulation is imported the below via air duct respectively, owing to be the air that sprays circulation from the below towards the top, so be compared to the ejection mode, the interior temperature distribution of each chamber can reach homogeneous.

On the other hand, if drive cooling fan, because half one, mixing duct and the air duct of the cold air of cup about via breather line is imported into the chamber, back, so can cool off chamber afterwards.At this moment, the air capacity that is equivalent to be imported into the air capacity of chamber, back can be returned cup via second half one of the left and right sides of breather line by the chamber, back.At this moment, be subjected to fan at once and attract and be cooled owing to supply to the cold air of back chamber of the relatively-high temperature of cup, so can not exert an influence reefer cargo at the heat exchanger place.

In addition, if electric heater work, the air that then is circulated throughout the chamber, back is heated by electric heater, so can prevent the supercooling of chamber, back.

And then, since can corresponding utilize smooth diapire inner face, about side wall inner surface and the square shape ground formation partition wall of the squarish that forms of the outside of flat breather line, so can be in simplified construction, guarantee and the confidentiality of the inner face of container by encapsulant, can suppress the leakage of the heat between cup and the chamber, back as much as possible.And, owing to do not restrict, can cooperate car loading at random to change the volume of cup and chamber, back being provided with on the position of partition wall.

In addition, because that the width of ventilation shaft spreads all over the width of roof is comprehensive,, can Min. will be suppressed to highly again so both can guarantee certain ventilation.Thereby, if consider between roof inner face and goods, to guarantee the passage of cold air, then can not exert an influence to the storehouse internal volume.

In addition, in reach in freezer of the present invention, if the diapire inner face at above-mentioned breather line is provided with heat-insulating material, then in via the chamber, cold air importing back of breather line with cup, when can also importing cup at cold air with the back chamber of relatively-high temperature, utilize the temperature difference of cold air with the cold air of chamber, back of cup, prevent in the outside of breather line reliably and the phenomenon of inner face generation dewfall.Thereby the dew that can not drip drenches goods.

At this moment, since partition wall 13 be arranged on encapsulant 13a around it be close to respectively seamlessly be close to the inner face that is arranged on smooth diapire 2a, about the inner face of sidewall 2c and the outside of the smooth breather line 14 of roof 2b described later, so can suppress as much as possible to transmit scriptures cup 2A and the leakage of the heat between the 2B of chamber afterwards.And, because the sectional area of the stainless-steel sheet of diapire 2a reduces significantly than the flooring material of T word shape, so also can reduce hot amount of movement widely.In addition, can also utilize between air blanketing 13d and the goods and guarantee air duct, prevent that goods contact partition wall 13 from directly passing to goods with heat.

On the other hand, at the inner face of the roof 2b of container 2, have the inner face width at interval of the sidewall 2c about approximate being equivalent to, and near being positioned at antetheca 2d an end opening at cup 2A, simultaneously, begin to be fixed with at a certain distance his end opening flat breather line 14 from rear wall 2e at back chamber 2B.This breather line 14 is about inside, the middle place of being bordering on of width is divided into by next door 14a (with reference to Fig. 2), wherein see antetheca 2d side from rear wall 2e side, it is set at right-hand ventilation path 14R can import to the cold air of cup 2A back chamber 2B, and the ventilation path 14L of left then can import to cup 2A with the cold air of back chamber 2B.

And, on left and right sides ventilation path 14R, 14L, pasted heat-insulating material 14b (with reference to Fig. 5 and Fig. 6) respectively at the diapire inner face of breather line 14.At this moment, because breather line 14 has the inner face width at interval of the sidewall 2c about approximate being equivalent to, so can guarantee enough throughputs and, the storehouse internal volume is not exerted an influence with highly being suppressed at irreducible minimum.That is, between roof 2b inner face and goods, need gap that cold air is passed through, can in this gap, take in breather line 14.

And then antetheca 2d side opening and rear wall 2e side opening place at the ventilation path 14L of the antetheca 2d side opening of right-hand ventilation path 14R and rear wall 2e side opening and left are provided with flashboard 15 respectively free to rotately.

Here, each flashboard 15 utilizes the deadweight locking each opening usually respectively, can be in the circulation that stops the air between cup 2A and the back chamber 2B, and the air that suppresses in the breather line 14 moves.On the other hand, when driving cooling fan 17 described later, each flashboard 15 anti-deadweight and rotating, can from cup 2A backward chamber 2B import cold air, in addition, also can import the cold air of relatively-high temperature to cup 2A from back chamber 2B.For example, as shown in Figure 5, when driving cooling fan 17, rotate, make rear wall 2e side opening open by the anti-respectively deadweight of flashboard 15, can be by the cold air importing back chamber 2B of right-hand ventilation path 14R with cup 2A.

In addition, rearward end at roof 2b, has the approximate inner face width at interval that is equivalent to left and right sides sidewall 2c, and when inside has mixing chamber 16a, be fixed with the mixing duct 16 of the case shape of the peristome that is communicated in mixing chamber 16a before and after having formed, in the mixing chamber 16a of mixing duct 16, be equipped with a cooling fan 17 and a plurality of circulating fan 18.And, on the front side peristome of the mixing chamber 16a that is provided with cooling fan 17 that is communicated in mixing duct 16, be connected with the other end (with reference to Fig. 6) of intake line 19 that an end is connected in the rear wall 2e side opening of right-hand ventilation path 14R.Simultaneously, on the front side peristome of the mixing chamber 16a that is provided with circulating fan 18 that is communicated in mixing duct 16, be provided with electric heater 29, this front side peristome is from the rear wall 2e of the ventilation path 14L of aforesaid left side opening, at a certain distance just at back chamber 2B opening (with reference to Fig. 2 and Fig. 7).And then the mixing chamber 16a that a rear side peristome subtend of mixing duct 16 is provided with circulating fan 18 forms, in addition, this peristome also be communicated in via encapsulant 16b be arranged on rear wall 2e inner face, at the upwardly extending air duct 21 of upper and lower.

Here, the mixing chamber 16a of mixing duct 16 utilizes next door 161 (with reference to Fig. 2) to distinguish between cooling fan 17 and the circulating fan 18 in the suction side that has set cooling fan 17 and circulating fan 18.Therefore, can the cold air of cup 2A only be imported cooling fan 17 via breather line 14, intake line 19.

Though at length do not illustrate freezing unit 3, but it is by comprising prime mover, for example being equipped with the Diesel engine of fuel tank, generator by diesel engine drives and utilize the refrigerating plant of power-actuated motor compressor that generator sends to constitute, its design can not kept refrigerating capacity with reaching setting-up time yet under railway transportation, boats and ships transportation, trailer transportation etc. have the situation of power source.

In addition, leading section (the inner face top of antetheca 2d) at roof 2b, when the evaporimeter of setting and refrigerating plant carries out the heat exchanger 22 of heat exchange, also be provided with and carried out the fan 23a of the cool-air feed of heat exchange by this heat exchanger 22 to cup 2A.And,,, also be provided with the air duct 21 that above-below direction extends for the below of will leading by the cold air that fan 23a supplies with at the inner face of antetheca 2d.

Here, freezing unit 3 state for controlling by control device (not have to illustrate), aforesaid cooling fan 17, circulating fan 18, electric heater 20 and fan 23a are connected with the control device distribution, carry out ON/OFF via control device and control.

Action to the reach in freezer 1 of such formation describes below.

At first, assemble ground at produce, when lath body 11A being set along antetheca 2d, after the outstanding rear end that cooperates lath body 11A has carried out being provided with the lath 11B of unit of suitable number in turn, utilize transportation such as fork truck goods (freezing product) to be loaded on lath body 11A and the lath 11B of unit with machine.If finished the loading of freezing product, partition wall 13 then is installed, after in container 2, being distinguished into cup 2A and back chamber 2B, when the diapire 2a as back chamber 2B is provided with the remaining lath 11B of unit, along rear wall 2e lath body 11A is set, similarly utilize transportations such as fork truck with machine with on goods (refrigerated item) lath 11B of the unit of being loaded into and the lath body 11A, locking rear wall 2e.

After this, to transporting reach in freezer 1 with providing and delivering.Be exactly to utilize the direct transported on trucks of trailer in specific words to dispensing ground, perhaps utilize trailer to be transported to the goods station, be transported to the goods station of destination at railway after, once more from goods station transported on trucks to dispensing ground, perhaps utilize trailer to be transported to the harbour, after boats and ships have been transported to destination port, once more from the harbour transported on trucks to dispensing ground.

Assembling ground from such produce when dispensing ground transports reach in freezer 1, should connect in advance and be used for controlling respectively cup 2A and to the two temperature tape-select switch (not having to illustrate) of refrigerated storage temperature freezing unit 3 worked to cryogenic temperature, back chamber 2B.

That is, the connection by two temperature tape-select switch drives Diesel engine, drives generator, and then utilizes the motor compressor of the driven by power refrigerating plant that generator sends.And if drive motor compressor, then refrigerant is compressed and supplies to condensed device, is cooled and becomes the liquid of high pressure at condensed device.After this, if make the refrigerant that has liquefied be ejected into evaporimeter via expansion valve, the refrigerant vaporization of then having liquefied is captured heat of gasification around the evaporimeter and is cooled off.The refrigerant that becomes gas is inhaled into motor compressor, carries out freeze cycle once more.

Here, the air of cup 2A is attracted by fan 23, after heat exchanger 22 carries out heat exchange and has been cooled, supplies to lath body 11A via the air duct 21 that is arranged on antetheca 2d, sprays towards the top from lath body 11A and the lath 11B of unit.Like this, the air of cup 2A capable of circulation, and control make cup 2A inner sustain at design temperature, for example maintain-20 ℃.

On the other hand, at back chamber 2B, circulating fan 18 is driven, and therefore, the air of back chamber 2B is recycled fan 18 and attracts, and supplies to lath body 11A via the air duct 21 that is arranged on rear wall 2e, sprays towards the top from lath body 11A and the lath 11B of unit.Like this, the air of back capable of circulation chamber 2B, and control make back chamber 2B inner sustain at design temperature, for example maintain 15 ℃.

Like this, at cup 2A and back chamber 2B, by down ejection, go up suction circulation cold air, can go up that the ejection mode is easier to make the storehouse temperature distribution reach homogeneous.

And then, if reaching, the internal temperature of the back chamber 2B that detects by temperature sensor 24 (with reference to Fig. 7) is higher than the design temperature uniform temperature, then drive cooling fan 17, make the flashboard 15 of attraction force acts to the rear wall 2e side opening place that is arranged on right-hand ventilation path 14R via intake line 19.Thus, the flashboard 15 at the rear wall 2e side opening place that is arranged on right-hand ventilation path 14R and the flashboard 15 opposing deadweights at antetheca 2d side opening place are rotated.Thereby, the cold air of cup 2A attracts via right-hand ventilation path 14R and the intake line 19 mixed pipelines 16 of breather line 14, supply to lath body 11A from cooling fan 17 side mixing chamber 16a via circulating fan 18 side mixing chamber 16a and the air duct 21 that is arranged on rear wall 2e, and spray towards the top from lath body 11A and the lath 11B of unit.

At this moment because the air of back chamber 2B circulates by circulating fan 18, so the mixing chamber 16a of mixing duct 16 mix the cup 2A that mixed pipeline 16 attracts cold air and after the cold air of chamber 2B, cool off at leisure.

Here, when right-hand ventilation path 14R by breather line 14 of the cold air of cup 2A because the internal temperature of back chamber 2B is than the cold air relatively-high temperature of cup 2A, thus may dewfall in breather line 14 outsides.But pasted heat-insulating material 14b by diapire inner face, can prevent dewfall at breather line 14.Therefore, the phenomenon that dew drenches goods that can not occur dripping.

In addition, because the Quilt with air conditioning cooling fan 17 of cup 2A supplies to back chamber 2B, so in the chamber 2B of back, produce malleation.Thus, the flashboard 15 opposing deadweight of the ventilation path 14L of left is rotated, air that will back chamber 2B via the ventilation path 14L of left supplies to cup 2A.That is, the air that supplies to back chamber 2B from cup 2A have only corresponding capacity from back chamber 2B circulation to cup 2A, so can always keep poised state.

At this moment, because the antetheca 2d side opening of the ventilation path 14L of the left of breather line 14 is opened near the antetheca 2d, attracted by fan 23a at once and be cooled at heat exchanger 22 so turn back to the cold air of the back chamber 2B of cup 2A.Thereby, can prevent that the quality that can not cause goods descends from afterwards chamber 2B circulation is to the goods (freezing product) of the cold air contact cup 2A of the relatively-high temperature of cup 2A.

Here, when the ventilation path 14L of the left of cold air by breather line 14 of the relatively-high temperature of back chamber 2B since the internal temperature of cup 2A after the cold air of chamber 2B be relative low temperature, so may dewfall at breather line 14 inner faces.But pasted heat-insulating material 14b by diapire inner face, can prevent dewfall at breather line 14.Therefore, dew can not occur drips from the cup 2A side opening end of breather line 14 or the connecting hole of pipeline etc. and drenches the phenomenon of goods.Like this, the air of back chamber 2B is cooled, if reach design temperature then temperature sensor 24 detects temperature, stops the driving of cooling fan 17.

On the other hand, if import back chamber 2B by cold air with cup 2A, perhaps based on the leakage of back chamber 2B to the heat of cup 2A, the temperature of chamber 2B becomes design temperature and drops to the above supercooling state of uniform temperature after making, then when cooling fan 17 is driving, stop the driving of cooling fan 17, simultaneously, make electric heater work, and when making the air circulation of back chamber 2B via circulating fan 18, the air that utilizes electric heater 20 heating to be attracted.If the air of back chamber 2B is heated and reaches design temperature then stop the action of electric heater 20.

Like this, when the temperature of back chamber 2B has been higher than design temperature, drive cooling fan 17, import chamber, back 2B cooled interior by cold air with cup 2A, perhaps, when the temperature of back chamber 2B has been lower than design temperature, make electric heater 20 work, by the air of heating and circulation back chamber 2B, can control simply, make the internal temperature of back chamber 2B maintain design temperature respectively.And, can transmit scriptures and lay electric wiring between freezing unit 3 and the back chamber 2B, than the situation that the cooling water of engine or high temperature refrigerant is imported back chamber 2B via pipe arrangement, can carry out operation simply, simultaneously, also not needing to consider the leakage of cooling water or refrigerant etc., is to have reduced the scheme that produces rough sledding.

Here, in the 1st example, illustrated to make diapire 2a form tabular surface, and having laid lath 11A, 11B after, utilized the situation of transporting, but explanation is that supposition can not use fork truck etc. to transport the situation of using machine with the machine loading goods.At this moment, can use the slide block of market sale, but can freely advance and retreat and free lifting ground has constituted the slide block handling goods of plane of load in order to being used as via cylinder.And then, corresponding to utilizing such slide block, can also be as shown in Figure 8, make the diapire 2a of container 2 have can the traveling slide block width, simultaneously, left and right sides width separate set the compartment of terrain from the antetheca 2d of container 2 up to rear wall 2e lay make when having in traveling plane of load than lath 11A, be projected into above the 11B above, when preserving, make plane of load than lath 11A, submerge above the 11B to below many tracks 25 of the degree of depth.

At this moment, in the lower surface of partition wall 13 rubber slab etc. is set vertically as encapsulant 13a, simultaneously, the shape ground of vertical sectional shape that comprises the floor of track 25 by correspondence forms encapsulant 13a, can with the situation of smooth diapire 2a similarly, be bordering between seamlessly airtight cup 2A and the back chamber 2B, the leakage from back chamber 2B to the heat of cup 2A is suppressed to Min..

The variation of＜the 1 example 〉

The general structure profilograph of the reach in freezer 100 of the variation that relates to the present invention's the 1st example shown in Figure 9.Here, with the same inscape of the 1st above-mentioned example on additional same reference marks, following explanation is primarily aimed at its difference and carries out.

On the top of the left and right sides of reach in freezer 100 sidewall 2c, be positioned at the below of the breather line 14 that is arranged on roof 2b described later, make the peristome subtend fix the guide rail 12 of cross section mutually for approximate C word shape.And then, on each guide rail 12,, embedded in front and back and can distinguish freely to rotate the moving body that axle has supported cylinder though there is not detailed icon, about moving body on linked partition wall 113 freely to rotate towards the rear via hinge respectively.

In addition, be provided with concavo-convex (not diagram) in the bottom of partition wall 113, can fastening to the hook (not diagram) of the rearward end that is arranged on breather line 14.

Thereby, be pressed into or pull out partition wall 113 by grip (not diagram), can make partition wall 113 move to the optional position of fore-and-aft direction along guide rail 12.And, can will install in position arbitrarily with the fastening portion of tying up track (not diagram) of ironware 13c fastening to the sidewall 2c inner face that is provided in container 2, by setting up fixed band 13b, can be arbitrarily between lath adjacent, promptly at interval partition wall 113 is fixed on position arbitrarily in the container 2 according to the length of the lath 11B of unit between the front end of the rear end of antetheca 2d side plate bar body 11A and rear wall 2e side plate bar body 11A.

Here, when loading or unloaded of cargo,, embossed card is fixed on be arranged on the hook of breather line 14, can keep along the favorite places of breather line 14 by the partition wall 113 that takeoffs.And then when partition wall 113 was in favorite places, breather line 14 was provided with the limit switch (not diagram) of action.

In addition, the detection signal of this limit switch or main switch (not diagram), be used for container 2 integral body control to cryogenic temperature or refrigerated storage temperature single temperature tape-select switch, be used for controlling respectively cup 2A to cryogenic temperature, afterwards chamber 2B is transfused to control device to the operation signal of two temperature tape-select switch of refrigerated storage temperature.

Action to the reach in freezer 100 of such formation describes below.

At first, assemble ground at produce, when lath body 11A being set along antetheca 2d, also the rear end of lath body 11A is outstanding in turn be equipped with the lath 11B of unit of right quantity after, utilize fork truck etc. to transport with machine lade (freezing product) on lath body 11A and the lath 11B of unit.If finished the loading of freezing product, then partition wall 113 is fallen from preservation state and be job state, and, will be distinguished into cup 2A and back chamber 2B in the container 2 by making it to move along the rear end of the lath 11B of unit and fixing.After this, the diapire 2a of chamber 2B is provided with in the remaining lath 11B of unit after formation, also along rear wall 2e lath body 11B is set, similarly, utilize fork truck etc. to transport with machine lade (refrigerated item) on lath 11B of unit and lath body 11A, locking rear wall 2e.

Then,, at this moment, when connecting main switch, also connect two temperature tape-select switch with providing and delivering, set cryogenic temperature and refrigerated storage temperature respectively, make freezing unit 3 work by display floater (not diagram) to transporting reach in freezer 100.

And when favorite places stationary partition 113, limit switch work also is input to the detection signal of limit switch the control device of freezing unit 3.Under this state, when connecting main switch, also when having connected two temperature tape-select switch,, make it to transfer to the control of the objective table of setting cryogenic temperature or refrigerated storage temperature at the guidance panel display abnormality and when giving the alarm.Thereby, owing to when can holding partition wall 113 to be in favorite places, do not carry out the control of two temperature bands, so can avoid reliably refrigerated item is cooled to cryogenic temperature.

Here, owing to be freezing or cold storage container 2 integral body by design temperature, so when having operated single temperature selector switch, can transfer to the next objective table of design temperature according to the detection signal that detected partition wall 113 is positioned at the limit switch of favorite places.

Its result when container 2 being divided into cup 2A and back chamber 2B and controlling each chamber according to design temperature respectively, has fixed at favorite places under the state of partition wall 113, can not carry out the control of two temperature bands, can prevent reliably that mistake is cooled to cryogenic temperature with refrigerated item.

As above-mentioned, the reach in freezer of the 2nd example can mix and carry the different goods of storage temperature by being target control (control of two temperature bands) control cup 202A and each chamber of chamber 202B, back with different separately design temperatures.In the 2nd example, cup 202A uses as the freezer of taking in the freezing preservation article that the freezing state that must keep chilled meat or frozen fish Jie class etc. transports, and back chamber 202B is as the freezer use of taking in the stored refrigerated article that the frozen state that must keep raw vegetable or cold drink etc. transports.

In addition, the design temperature of chamber, back (below be referred to as " freezer ") 202B is set on the design temperature ground that is lower than cup (below be referred to as " freezer ") 202A, and as above-mentioned, by the cold air importing freezer 202B side of outlet side ventilation path 214R with freezer 202A, carry out the temperature control of freezer 202B, under the situation that the excessive temperature of freezer 202B descends, can control with holding temperature by electric heater.

Here, the temperature of so-called freezer 202B too descends and can consider following such situation.Promptly, because the storehouse temperature of freezer 202A is controlled in-20 ℃～-30 ℃ degree, the storehouse temperature of freezer (cooling) 13 is controlled in+5 ℃ of front and back, therefore, even the obstructed ventilation path of trackside in the past 214R also can be by this temperature difference via cold and hot the be delivered to freezer 202B side of partition wall 13 with freezer 202A side to freezer 202B side with the cool-air feed of freezer 202A, exist owing to cooled off the interior and situation that too descend from design temperature of freezer 202B.In addition, for example, occasion when the situation etc. of article is transported in Hokkaido, situation about from design temperature too descending the outside air temperature cooling refrigeration storehouse 202B in Hokkaido in also can occur even utilize from Osaka in the winter time.Under these circumstances, need control, utilize in the electric heater 20 warm storehouses, maintaining design temperature (+5 ℃) in the storehouse.In addition, sometimes also need to consider to control, in freezer 202A side is passed through electric heater 220 warm storehouses, to keep the inherent design temperature (20 ℃～-30 ℃) in storehouse.

Like this, in the control of two temperature bands, existence need be main with the compressor of refrigerator 23 and the situation of the electric heater 20 of the freezer 202B that turns round simultaneously.But, as above-mentioned, if the electric heater 20 of the compressor of the refrigerator 23 that turns round simultaneously and freezer 202B then the rough sledding that generator is overload state and so on can occur.Therefore, in the 2nd example, adopt and to control by control device, a certain side who makes the compressor of refrigerator or electric heater 20 is in operation process and stop the formation of an other side's running.At this moment, the relative importance value that adopts a certain side preestablish preferential compressor or electric heater 20 to control, and according to a certain side's of this relative importance value control compressor or electric heater 20 formation.

Shown in Figure 13 is to carry out the functional block diagram that the summary of control system of the control of two temperature bands constitutes in the reach in freezer 200 of above-mentioned formation.

That is, on the control part 51 of all control of watching the palm two temperature bands, be connected with a plurality of temperature sensors 52 (and even but in Figure 10 Figure 12, not illustrating) of the suitable position that is arranged on freezer 202A and freezer 202B.In addition, control part 51 is being connected in when ON/OFF drives the heater-driven portion 53 of each electric heater 20,220, also is connected in the fans drive portion 54 of ON/OFF control cooling fan 17, circulating fan 18 and circulating fan 218.In addition, control part 51 can also drive the compressor of control refrigerator 23.Though omitted diagram, control part 51 also possess the CPU that carries out various calculation process arranged, preserve the temperature control program of two temperature bands ROM, as each temperature detection data of storage or when carrying out temperature control as the RAM of working region work etc.

Below, the concrete example of the common cold insulation running control of the common cold insulation running control of freezer side and freezer side is described, at last to describing based on the cold insulation running control that relates to relative importance value of the present invention.

(1) the common cold insulation running control of freezer side

Shown in Figure 14 is the flow chart of the common cold insulation running control processing of freezer side.Handle below with reference to flowchart text cold insulation running control shown in Figure 14.Here, the design temperature of getting freezer 202A is for for example-25 ℃, and the storehouse temperature control accuracy of freezer 202A is+1 ℃～-2 ℃.In addition, the freezer side temperature deviation of getting as the difference of the storehouse temperature of the design temperature of corresponding freezer 202A is Δ T1.In addition, also establish circulating fan 218 and be in frequent running.

The temperature sensor that do not have illustrated assigned position place 52 of control part 51 by being arranged on freezer 202A detects storehouse temperatures, judge freezing side temperature deviation Δ T1 as the difference of the design temperature of its detected temperatures and freezer 202A whether surpassed as control accuracy+1 ℃ (step S11).Surpassed at Δ T1 consequently+1 ℃ the time (when step S11 is judged as "Yes"), open compressor starts running (step S12).On the other hand, after the running that has begun compressor, judge whether Δ T1 has reached below-1 ℃ (step S13).When consequently reaching below-1 ℃ (when step S13 is judged as "Yes"), close compressor (step S14).

Control part 51 is controlled by above-mentioned repeatedly processing (processing of step S11～step S14) basically, and the storehouse temperature of freezer 202A is in-25 ℃ ± 1 ℃ the scope as design temperature.

On the other hand, in the ON/OFF control of such compressor, control part 51 often monitors whether Δ T1 has reached below-2 ℃ (step S15).This is to consider only to pass through as above-mentioned so out of contior other the key element (influences of for example above-mentioned outdoor temperature etc.) of the ON/OFF of compressor.

And, when Δ T1 has reached below-2 ℃ (when step S15 is judged as "Yes"), will judge in the freezer 202A coldly excessively, and then open electric heater (Defrost heater) 220 (step S16).And then if storehouse temperature reaches design temperature, promptly Δ T1 is that 0 (when step S17 is judged as "Yes") then closed electric heater (Defrost heater) 220 (step S18), returns step S11.

(2) explanation of the common cold insulation running control of freezer side

Shown in Figure 15 is the flow chart of the common cold insulation running control processing of freezer side.Handle below with reference to flowchart text cold insulation running control shown in Figure 15.Here, the design temperature of getting freezer 202B is for for example+5 ℃, and the storehouse temperature control accuracy of freezer 202B is ± 2 ℃.In addition, the freezer side temperature deviation of getting as the difference of the storehouse temperature of the design temperature of corresponding freezer 202B is Δ T2.In addition, also establish circulating fan 18 and be in frequent running.

The temperature sensor that do not have illustrated assigned position place 52 of control part 51 by being arranged on freezer 202B detects storehouse temperatures, judge refrigeration side temperature deviation Δ T2 as the difference of the design temperature of its detected temperatures and freezer 202B whether surpassed as control accuracy+1 ℃ (step S21).Surpassed at Δ T2 consequently+1 ℃ the time (when step S21 is judged as "Yes"), open cooling fan 17 entrys into service (step S22).On the other hand, after the running that has begun cooling fan 17, judge whether Δ T2 has reached below-0.5 ℃ (step S23).When consequently reaching below-0.5 ℃ (when step S23 is judged as "Yes"), closing cool air fan 17 (step S24).

Control part 51 is controlled by above-mentioned repeatedly processing (processing of step S21～step S24) basically, make the storehouse temperature of freezer 202B be in Zi as design temperature+5 ℃ to+1 ℃～-0.5 ℃ scope in.

On the other hand, in the ON/OFF control of such cooling fan 17, control part 51 often monitors whether Δ T2 has reached below-1 ℃ (step S25).This is to consider only to pass through as above-mentioned so out of contior other the key element (the transmission from one channel to another partition wall 13 of for example above-mentioned freezer 202A comes the influence of cold and hot or outdoor temperature etc.) of the ON/OFF of cooling fan 17.

And, when Δ T2 has reached below-1 ℃ (when step S25 is judged as "Yes"), will judge in the freezer 202B coldly excessively, and then open electric heater 20 (step S26).And then, if Δ T2 surpasses 0.5 ℃ (when step S27 is judged as "Yes") then closes electric heater 20 (step S28), return step S21.

(3) explanation of controlling based on the cold insulation running of relative importance value

In the 2nd example, basically be to carry out the common cold insulation running control of above-mentioned freezer side and the common cold insulation running control of above-mentioned freezer side individually, at this moment, when the overlapping state has appearred in the running of compressor and electric heater 20, have precedence over the cold insulation running control that following explanation is implemented in above-mentioned each cold insulation running control based on relative importance value.
