Firstly, being illustrated to the detailed configuration of refrigerated cooler 24.As shown in Fig. 2, refrigerated cooler 24 has:
The collector 24a of entrance as refrigerant, as refrigerant outlet collector 24b, connect these collectors 24a and collector 24b
Between flat tube 24c, be set between each flat tube 24c and by the fin 24d of the rugose heat absorption of metal material shape,
It is set to the collector 24a of entrance side and the entrance side interconnecting piece 24e that is connect with refrigerant piping (illustration omitted) and is set to
The collector 24b of outlet side and the outlet side interconnecting piece 24f being connect with outside pipe arrangement (illustration omitted).At this point, flat as being provided with
The shape of the main part 24g at the position of flat pipe 24c is known as substantially thin rectangular-shape.
Collector 24a and collector 24b are formed hollow cylindrical, become mutual hollow portion (illustration omitted) and pass through respectively
Flat tube 24c and the state being respectively communicated with.More specifically, as shown in figure 3, the shape of flat tube 24c be formed it is flat, and
And be formed in the interior thereof for refrigerant flowing multiple flow paths for 24 hours.Moreover, collector 24a's and collector 24b is mutual hollow
Portion is connected to for 24 hours by each flow path.
By the way that multiple flow paths are arranged like this for 24 hours, compared with previous such type for being provided with one large-scale flow path,
The contact area of refrigerant and flat tube 24c increase.Heat is efficiently transfer to flat tube 24c from refrigerant as a result,.In addition,
Since flat tube 24c is contacted with fin 24d, heat can also be efficiently transfer to fin 24d from flat tube 24c.Moreover, by
It is formed in fin 24d wavy, therefore can further increases and the contact area of air i.e. heat exchange area.
Since in this way, multi-flow type refrigerated cooler 24 can carry out efficient heat exchange between air.For example, right
It, then, being capable of the phase compared with the refrigerated cooler of previous fin tube type if fruit volume is identical for refrigerated cooler 24
To 2~3 times of endothermic effect, on the other hand, as long as if obtaining endothermic effect same, it being capable of shape
At slim etc., volume can be significantly cut down.Refrigerated cooler is configured in the back side of refrigerator 1 as the method as a result,
In the case where 24, the idle space that can cut down back side is not used as the space of storeroom.
In addition, in the case where the method, as shown in figure 4, refrigerated cooler 24 is configured as the collector 24a of entrance side
It is located below, the collector 24b of outlet side is located above.In other words, refrigerated cooler 24 is configured as configured with flat
The main part 24g at the position of pipe 24c and is configured as flat tube 24c and is also perpendicularly to be arranged perpendicular to the setting face of refrigerator 1
Face.In addition, said here be vertically not limited to setting face in 90 degree of state, it also include that can be considered substantially vertical shape
State, such as the state being slightly tilted.
The refrigerant for flowing into refrigerated cooler 24 is flowed with liquid condition from entrance side interconnecting piece 24e as shown by arrow F
Enter refrigerated cooler 24, is evaporated in refrigerated cooler 24 as after gaseous state, connected from the outlet side of top
Portion 24f mainly becomes gaseous state and flows out.At this point, the refrigerant of liquid condition flows down downwards because of gravity, therefore, such as scheme
As showing schematically in 4 (B), the entrance of refrigerant is set to lower section, outlet is set to top, thereby, it is possible to make
The movement of refrigerant is smooth, and is able to carry out efficient heat exchange.In addition, Fig. 4 (B) is showed schematically from diagram left side
The state of refrigerated cooler 24 shown in Fig. 4 (A).
In addition, temperature reduces and generates frost if the refrigeration cycle of refrigerated cooler 24 operates.The frost makes heat exchange
It can reduce, thus, for example just carrying out removing the defrosting processing of frost during certain.In defrosting processing, accompanying frost
It is melted into defrosted water and is discharged downwards.Therefore, by as the method vertically configure refrigerated cooler 24 main body
Portion 24g can promote defrosted water to flow down.Moreover, flat tube 24c is also configured as vertically, defrosted water is easy in flat tube as a result,
24c conduction, can further promote to flow down.
Refrigerator 1 from the description above, can obtain following effect.
Heat exchange of the refrigerator 1 using multi-flow type refrigerated cooler 24 (evaporator) Lai Jinhang refrigeration cycle, the multi-flow type
Refrigerated cooler 24, which has, is formed with the flat tube 24c of multiple flow paths for refrigerant flowing for 24 hours in inside.
The heat exchange performance as described above of multi-flow type refrigerated cooler 24 is high, if performance is identical, with previous fin
The refrigerated cooler of tubular type is compared, its volume can be significantly cut down.Further, since can be realized slimming, and therefore, configuration
The freedom degree in place also improves.Therefore, it can be improved the freedom degree of the configuration of refrigerated cooler 24, and can obtain effective
Case inner volume can be used as space in the case of storeroom.
In addition, defrosted water can be promoted to flow down by the main part 24g for vertically configuring refrigerated cooler 24.The feelings
Under condition, flat tube 24c is also configured as vertically, defrosted water is easy to conduct in flat tube 24c as a result, can further promote to remove
Under white water flow.
In addition, as the method with refrigerated cooler 24 and freezing cooler 25 the two evaporators
In the case of, every circulating defrosting can be carried out to refrigerated cooler 24 by each actuation cycle.If refrigerant flows, refrigerate
Cooled with cooler 24, on the other hand, the temperature inside the box of refrigerating chamber 3 is 0 DEG C or more, therefore, if refrigerant does not flow,
Rotate refrigeration blowing fan 35 persistently, thus, it is possible to be heated to defrost to evaporator.
At this point, since the thermal capacity of multi-flow type refrigerated cooler 24 becomes smaller, the refrigeration with previous fin tube type
It is compared with cooler, defrosting time shortens, and is able to carry out efficient operating, and it is possible to realize the savings of electric power.
In addition, entrance side interconnecting piece 24e and outlet side interconnecting piece 24f are set as substantially parallel with main part 24g, because
This, can make the length (thickness) forward and backward of refrigerated cooler 24 thinning, storeroom can be made to become larger.
In addition, can also obtain effect same as refrigerated cooler 24 about freezing cooler 25.
< second method >
Hereinafter, being illustrated referring to Fig. 5 to Figure 10 to second method.In second method, to refrigerated cooler 24
Other of configuration mode and construction example are illustrated.
As described above, the lower side of refrigerated cooler 24 can flow down defrosted water, therefore, if (flowing down region in this range
(Rx.Referring to refrigeration blowing fan 35 is configured in Fig. 7), then when having carried out defrosting processing, defrosted water can probably drop to refrigeration and use
Blowing fan 35.
Thus, for example in the case where being configured in refrigerator cooler room 36 as illustrated in fig. 5, it is contemplated that will be used for
The fan 60 blown to refrigerated cooler 24 is configured at the position substantially parallel with refrigerated cooler 24.In addition, fan 60
It is also possible to refrigeration blowing fan 35.
Thereby, it is possible to prevent the defrosted water flowed down by gravity from dropping to fan 60.In addition, refrigerating if it is multi-flow type with cold
But device 24, then can be formed as described above it is slim, accordingly it is also possible to be set side by side in refrigerator cooler room 36 with fan 60
It sets.
In this case, the lower side in refrigerated cooler 24 is provided with water storage container 56 (referring to Fig.1) and therefore passes through
The space of the water storage container 56, the lower side of refrigerated cooler 24 becomes on the inside of case by the state of Partial Blocking.In the state
Under make fan 60 rotate in the case where, side is inhaled into fan 60 to air stream from below first as depicted by arrow B, later,
It is discharged upwards across refrigerated cooler 24.
That is the fan 60 is configured at the upstream side i.e. weather side of the flow path of the wind relative to refrigerated cooler 24.
Even if as a result, at the refrigerated cooler 24 caused by frost in the case where disperse or evaporate, also can prevent moisture from hanging to wind
Fan 60.
Alternatively, fan 60 can be configured at and be refrigerated with cold in the case where being configured in cold duct 34 as illustrated in fig. 6
But the upper side of device 24.Thereby, it is possible to prevent defrosted water from hanging to fan 60.In this case, it is contemplated that side is sucked up from below
The water droplet that the air come is discharged upwards after refrigerated cooler 24 like that as shown by arrow B, but disperses can be because of weight
Power and move downwards, therefore, hanging to a possibility that fan 60 reduces.
Alternatively, as shown in Figure 7, it is envisioned that even in the lower section of refrigerated cooler 24, but if being from defrosted water
Flow down region (Rx) that is the position that the range of the underface of substantially refrigerated cooler 24 deviates, then can also prevent from removing
White water is hung to fan 60.At this point, being configured fan 60 when with refrigerated cooler 24 is passed through relative to refrigerated cooler 24
The opposite side of wind direction.
Wind direction when in the case of fig. 7, across refrigerated cooler 24 is diagram towards a left side, and therefore, fan 60 is arranged
In than refrigerated cooler 24 by illustrate right side.Even if be attached to as a result, the surface of refrigerated cooler 24 it is white because
Wind and disperse, also can reduce a possibility that extension is to fan 60.
Like this, as long as refrigerated cooler 24 is located at the flowing down outside region of defrosted water, arbitrary position can be configured at
It sets.Thus, for example in Fig. 6, if there are spaces in diagram left and right directions, also fan 60 can be configured at and refrigerated with cold
But the oblique upper etc. of device 24.
In addition, as shown in figure 8, refrigerated cooler 24 horizontally can be configured relative to the setting face of refrigerator 1.Separately
Outside, it is described herein it is horizontal include that can regard approximate horizontal state as, such as the state being slightly tilted.
By substantially horizontally being configured like this, the required space of short transverse can be cut down.Further, since can
It is configured along top or is configured at insulation segregated portion, therefore, case internal volume can be made to increase.
In this case, can prevent defrosted water from hanging to wind by the top that fan 60 is configured to refrigerated cooler 24
Fan 60.In addition, being capable of increasing main part 24g to obtain surface area, or by keeping main part 24g thin by being set as approximate horizontal
Change come the reduction of the raising and required space of seeking the freedom degree of setting.
In addition, wind direction is set as upward in Fig. 8, that is it is set as from refrigerated cooler 24 to the direction of fan 60, but
The frost removed from refrigerated cooler 24 moves downwards because of gravity, and therefore, wind direction will not become problem.In addition, pass through by
Wind direction is set as downward, that is is set as to further suppress and using from refrigeration from fan 60 to the direction of refrigerated cooler 24
The frost that cooler 24 is removed is attached to fan 60.
In addition, up to the present, as refrigerated cooler 24, being said to the refrigerated cooler of so-called parallel type
It is bright, but refrigerated cooler 24 can also use the refrigerated cooler of dioptric type like that as illustrated in fig. 9.The refrigeration of dioptric type
It is so that a flat tube 24c is turned back and be connected to outlet from the entrance of refrigerant with the structure that cooler 24 is formed.It is flat at this
The entrance side of the refrigerant of pipe 24c is provided with collector 24a, and the outlet side of refrigerant is provided with collector 24b.In addition, being rolled over
Fin 24d is provided between the flat tube 24c returned.
Even the refrigerated cooler 24 of such a dioptric type, also with the refrigeration of parallel type shown in first method
Similarly with cooler, heat exchange performance is high, if it is same performance then with the refrigerated cooler phase of previous fin tube type
Than can significantly cut down its volume, thinning can be realized, therefore, the freedom degree for configuring place also improves, so as to obtain
It can be used as the effective case inner volume of storeroom.
In addition, the refrigerant of liquid condition flows into, and as described previously for refrigerated cooler 24 with gaseous state stream
Out.The so-called time liquid that clean refrigerant is flowed out with liquid condition is not evaporated at this point, may generate.
Therefore, schematically show in the refrigerated cooler 24 of the parallel type schematically illustrated in Figure 10 (a), Figure 10 (b)
In the refrigerated cooler 24 of dioptric type out, make the volume of the collector 24b of outlet side formed than entrance side collector 24a
Volume is big.In addition, Figure 10 schematically illustrates the difference of volume by the difference of collector 24a and the diameter of collector 24b.
The collector 24b of outlet side is functioned as liquid storage device as a result, can reduce in refrigerated cooler 24
A possibility that rear section side refrigerant maintains liquid condition to be recycled.In addition, can also be sought if can ensure enough volumes
Seek no reservoir.
In addition, can also obtain effect same as refrigerated cooler 24 about freezing cooler 25.
< Third Way >
Hereinafter, 1 to Figure 13 being illustrated referring to Fig.1 to Third Way.In Third Way, to refrigerated cooler 24
Other examples of setting place are illustrated.
The example of the rear configuration refrigerated cooler 24 of the shock chamber 14 in refrigerating chamber 3 is shown in first method
Son, but refrigerated cooler 24 can also be configured at other places.
For example, as shown in figure 11, refrigerated cooler 24 can be configured to the inside of refrigerator 1 and be top side and back
Surface side (hereinafter, for convenience and referred to as top rear face side).Although the size according to refrigerator 1 is also different, refrigerator 1 it is upper
Portion's back side refers to that hand is relatively difficult to the place touched when picking and placing food materials relative to refrigerating chamber 3.In addition, multi-flow type refrigeration cooling
Device 24 is miniaturized as described above, therefore its required space also becomes smaller.
Therefore, by ensuring the space of refrigerator cooler room 36 in top rear face side and configuring refrigerated cooler herein
24, it can effectively apply flexibly hand and relatively be difficult to the place touched.In addition, the rear side in shock chamber 14 does not need refrigeration cooling
Therefore the space of device room 36 is capable of increasing shock chamber 14.
In this case, as shown in figure 12, refrigerated cooler 24 and refrigeration blowing fan 35 (referring to Fig. 5) is set side by side simultaneously
They are configured at top rear face side, free space, therefore, vegetable can be formed at the rear of vegetable compartment 4 in this mode as a result,
It dish room 4 also being capable of enlargement.
In addition, as shown in figure 13, refrigerated cooler 24 and refrigeration blowing fan 35 (referring to Fig. 5) being set side by side and is inciting somebody to action
In the case that they are configured at the rear of shock chamber 14, vegetable compartment 4 can be made enlarged.
Like this, by using multi-flow type refrigerated cooler as refrigerated cooler 24, not only refrigeration cooling
Device 24, the configuration place of refrigeration blowing fan 35 and the freedom degree of configuration mode also improve.Thereby, it is possible to effectively apply flexibly food materials
The difficult top rear face side etc. of pick-and-place, the effective case inner volume that can be used as storeroom can be obtained.In addition, being used about freezing
Cooler 25 can also obtain effect same as refrigerated cooler 24.
The more a configuration mode > of <
Firstly, being illustrated to the background of multiple configuration modes.In the past, it was cooled down in the storeroom to different temperatures band
When, refrigerating chamber 3, freezing chamber 7 are cooled down by different coolers respectively.But have in recent years as substantially same
Refrigerating chamber 3, vegetable compartment 4 or the shock chamber 14 of one temperature band, the ice-making compartment 5 as substantially same temperature band, small freezing chamber 6 or
The structure of multiple storerooms of same temperature band as freezing chamber 7 etc. is increasing.
Like this there are in the case where the storeroom of multiple same temperature bands, in the cooling carried out by a cooler
In, it needs to be laid with cold duct, the case internal volume that can be used as storeroom correspondingly reduces.In addition, according to same temperature
The storeroom for spending band uses the composition of multiple coolers, then in the cooler of previous fin tube type, cooler has certain
The size of degree, therefore, case internal volume can still reduce.
Therefore, in multiple configuration modes, by it is multiple have be formed with multiple flow paths for refrigerant flowing in inside
The multi-flow type evaporator of flat tube 24c (referring to Fig. 2 etc.) is used for the cooling to the storeroom of same temperature band.Hereinafter, to setting
The specific composition example of multiple multi-flow type evaporators is illustrated.
Figure 14 schematically illustrates the refrigerator 100 of the method.The top layer side of the refrigerator 100 is provided with refrigerating chamber 3, at it
It is provided with to lower section left-right situs ice-making compartment 5 and small freezing chamber 6, vegetable compartment 4 is provided with below these, is arranged thereunder
There is freezing chamber 7.Here, that is the storeroom that refrigerating chamber 3 and vegetable compartment 4 are refrigerating temperature zones is substantially same temperature band
Storeroom, ice-making compartment 5, small freezing chamber 6 and freezing chamber 7 are that is the storeroom of cryogenic temperature band is substantially same temperature
Spend the storeroom of band.
That is, in the case where refrigerator 100, configured with not between the refrigerating chamber 3 and vegetable compartment 4 of same temperature band
The ice-making compartment 5 and small freezing chamber 6 of synthermal band.Moreover, the 1R that refrigerator 100 has for carrying out cooling to refrigerating chamber 3 is cold
But device 110, for carrying out cooling 2R cooler 111, cold for carrying out to ice-making compartment 5 and small freezing chamber 6 to vegetable compartment 4
But 1F cooler 112 and the 2F cooler 113 for carrying out cooling to freezing chamber 7.In addition, leading between each storeroom
Insulation demarcation plate 101 is crossed to separate.
It, can be with if volume is identical compared with previous fin tube type construction as described previously for multi-flow type evaporator
2~3 times of endothermic effect is expected, on the other hand, if as long as acquisition and previous same endothermic effect, can be realized
Miniaturization and thinning, can significantly cut down required installation space.Therefore, it is used by the storeroom to same temperature band more
A multi-flow type evaporator is able to suppress case internal volume and is greatly reduced.That is, multi-flow type cooler (evaporator) and previous fin
The cooler of tubular type is compared, and it is possible to realize slimming and miniaturizations.
In addition, such as can not also be connected between refrigerating chamber 3 and vegetable compartment 4 by cold duct, it is therefore not necessary to spread
If cold duct, the reduction of case internal volume can be prevented.
In addition, distinguishing in 1R cooler 110,2R cooler 111,1F cooler 112 and 2F cooler 113
It is provided with blowing fan 120~122.Thus, it is possible to promote the heat exchange at each cooler, endothermic effect can be improved.
Here, to the company of 1R cooler 110,2R cooler 111,1F cooler 112 and 2F cooler 113
The mode of connecing is illustrated.
Firstly, Figure 15 schematically illustrates connection type when cooler is connected in series.In this case, for 1R
Cooler 110 and 2R cooler 111, for example, by the switching valve 104 being made of triple valve switch over for refrigeration
In the path of the refrigerant flowing of temperature band, 1R cooler 110 is connected to upstream side, and it is cold to be connected with 2R in side downstream
But device 111.
Similarly, for 1F cooler 112 and 2F cooler 113, in the confession switched over by switching valve 104
In the path of the refrigerant flowing of cryogenic temperature band, 1F cooler 112 is connected to upstream side, is connected with the in side downstream
2F cooler 113.These coolers and compressor 27, condenser 103 together constitute with refrigeration cycle 105.
Like this, by the way that cooler is connected in series, it is no longer necessary to individually to refrigerant to the flow path of each cooler
Therefore the composition switched over respectively is able to suppress the increase of cost.
In addition, in the case where configuring the storeroom of multiple same temperature bands in non-conterminous position as the method,
That is passing through multiple coolers in the case where being provided with the storeroom of different temperatures band between the storeroom of same temperature band
Different storerooms is cooled down respectively, as a result, without being laid with cooling pipe, can significantly inhibit the drop of case internal volume
It is low.
On the other hand, Figure 16 schematically illustrates connection type when being connected in parallel to cooler.In this case, for example
By the switching valve 104 being made of five-way valve or multiple triple valves, for 1R cooler 110,2R cooler 111,1F
Cooler 112 and 2F cooler 113 separately switch the path for refrigerant flowing.
Like this, by being connected in parallel to cooler, can individually to flow path from refrigerant to each cooler into
Row switching, can be such that each cooler operates with evaporating temperature appropriate, can promote energy-saving.
In addition, each cooler respectively cools down different storerooms.As in the past by a cooler to same
In the case that the storeroom of one temperature band carries out cooling, such as when cooling down to refrigerating chamber 3, vegetable compartment 4 is also inevitable cold
But.Therefore, even if not opening/closing to vegetable compartment 4, vegetable compartment 4 may also can be cooled, but by by different coolings
Device respectively cools down different storerooms, even if the door in such as refrigerating chamber 3 is opened/closed and the temperature of refrigerating chamber 3
In the case where rising, also only refrigerating chamber 3 can be cooled down.That is, each storeroom individually can be maintained respectively suitable
When temperature.Further, since using compact-sized cooler, so will can inhibit smaller to the influence of case internal volume.
In addition, the composition of the storeroom of refrigerator 100 shown in Figure 14 is an example, such as following structure can also be used
At: by vegetable compartment 4 and the exchange of the sequence of freezing chamber 7 in Figure 14, refrigerating chamber 3 is configured at top layer, vegetable compartment 4 is configured at
Lowest level.In this case, following composition can also be used: by different coolers respectively to 3 He of the refrigerating chamber of configured separate
Vegetable compartment 4 is cooled down, and ice-making compartment 5, small freezing chamber 6, the freezing chamber 7 being configured adjacently are cooled down by a cooler.
That is even the refrigerating chamber 3 of the storeroom refrigerating temperature zone as same temperature band, vegetable compartment 4 or Quench
Any of room 14 or their combination also can be carried out efficiently the cooling of the storeroom of refrigerating temperature zone.Similarly,
Even any of the ice-making compartment 5 of the storeroom cryogenic temperature band as same temperature band, small freezing chamber 6 or freezing chamber 7
Or their combination, it also can be carried out efficiently the cooling of the storeroom of cryogenic temperature band.In addition, even if not having ice making
It, also can be using composition illustrated in this mode in the case where room 5, small freezing chamber 6.
In addition, as shown in figure 17, it, can be using in shock chamber 14 in the case where shock chamber 14 are provided in refrigerating chamber 3
3R cooler 114 is set and separately carries out cooling composition to refrigerating chamber 3, vegetable compartment 4 and shock chamber 14.The feelings
Under condition, such as the temperature etc. of setting shock chamber 14 is allowed users to, thereby, it is possible to be eaten within the scope of more appropriate temperature
The preservation of product etc., can be improved convenience.I.e., it is possible to using the composition of setting three or more the storerooms of same temperature band.
