Heat, temperature is gone to be declined to become cold air.Rise in pipeline 12 by the cold air of the evaporator 23.What is risen in pipeline 12 is cold
A part for gas guides each cold air blow-off outlet 7 by guide plate 25ax, 25ay, 25b, is blown from each cold air blow-off outlet 7 to showroom 4
Go out.The cold air of blowout cools down the commodity on each shelf 5.
Due to the effect of guide plate 25ax, 25ay, 25b into, cold air can expeditiously be guided to each cold air blow-off outlet 7.It is special
It is not the protrusion length T of the planar portions B of the protrusion length T and guide plate 25b of the planar portions B due to making guide plate 25ax, 25ay
Difference, from each side blowing portion 7ax, 7ay of each cold air blow-off outlet 7 and the cold air of the other Chui Chu Fitness amounts of center blowing portion 7b Fen.
If the protrusion length of the planar portions B of the protrusion length T and guide plate 25b of the planar portions B of guide plate 25ax, 25ay
T-phase is same, and the ventilatory capacity of the per unit area of the opening of each side blowing portion 7ax, 7ay will be than center blowing portion 7b's in this case
The ventilatory capacity of the per unit area of opening is few.
In the case of this implementation form, make the planar portions of guide plate 25ax, 25ay corresponding with each side blowing portion 7ax, 7ay
The protrusion length T long of the planar portions B of the protrusion length T guide plate 25bs more corresponding than with center blowing portion 7b of B, therefore can incite somebody to action
The ventilatory capacity of the per unit area of the opening of each side blowing portion 7ax, 7ay is set as the per unit with the opening of center blowing portion 7b
The ventilatory capacity of area is identical or more than its.Using this setting, the commodity that two corner of front side of each shelf 5 can be placed
Convey sufficient cold air.That is, all commodity on each shelf 5 can access appropriate cooling.
Above-mentioned freeze cycle, cold air blow-off outlet 7, pipeline 12, suction inlet 13, pipeline 14a, fan 22, guide plate 25ax,
25ay, 25b and following adjustment plate 25z etc. constitute the cooling end to providing cold air in showroom 4.
On the other hand, the pipeline 11 in the cold air inflow top plate 2 on 12 top of pipeline is reached.The cold air of flow ipe 11 is drawn
To gas curtain blow-off outlet 10, blown downwards from each side blowing portion 10ax, 10ay and center blowing portion 10b of the gas curtain blow-off outlet 10
Go out.
Before the cold airflow blown out from each side blowing portion 10ax, 10ay and center blowing portion 10b is formed along showroom 4
The gas curtain of face opening portion 41, left side opening portion 42, right side opening portion 43.By means of the gas curtain, can prevent outside main body 1
Invade the extraneous air of showroom 4.Since the intrusion of extraneous air can be prevented, can improve to the cold of the commodity in showroom 4
But efficiency.
The cold air flowed downwards is blown out from gas curtain blow-off outlet 10 and is blown out from cold air blow-off outlet 7 on each shelf 5
Commodity carry out cooling cold air, and the suction inlet 13 of negative pressure state is in expeditiously because of the operation of fan 22 with admixture
Sucking.The mixed gas for being inhaled into the sucking of mouth 13 flows to evaporator 23 by pipeline 14a, is recycled by above-mentioned path.
In this way, even three faces with front openings portion 41, left side opening portion 42, right side opening portion 43 are opening
Showroom 4, can also carry out uniform and efficient cooling to the commodity on each shelf 5.To the commodity in showroom 4,
It can confirm from front side, left side surface side, right side surface side any direction, can see.So as to improve the exhibition of commodity
Show effect.In the case that even 41 front someone of front openings portion stands, the commodity in showroom 4 are also easy to pass through left side
Opening portion 42 or right side opening portion 43 are taken out without hindered.Thus, it is possible to improve the marketing efficiency of commodity.
Since the size Fa and the relationship of the size Fb of the front and back longitudinal direction of main body 1 of the left and right width direction of main body 1 are
Fa≤Fb, main body 1 closely, while can reduce the setting area of main body 1.Even thus small-scale convenience store or ratio
Main body 1 can be also arranged in the shops such as the supermarket of small-scale.The shipping of main body 1 and the work for moving in setting place be also easy into
Row.
But, it is necessary to seek the blowout amount of the cold air blown out forwards from cold air blow-off outlet 7 with from gas curtain blow-off outlet 10
The optimal allocation of the blowout amount of the cold air blown out downwards.
In each cold air blow-off outlet 7, also it is necessary to seek the blowout air quantity from each side blowing portion 7ax, 7ay to be blown out with from center
The optimal allocation of the blowout air quantity of portion 7b.The wind Zhi Jin blown out from each side blowing portion 7ax, 7ay and center blowing portion 7b
Also it is important.The space of position corresponding with the cold air blow-off outlet 7 of lowest part in space especially in pipeline 12, it is just logical
The Strong cold wind of pervaporation device 23 is blown upward.The surface current of cold wind upward, major part against smooth partition board 19 is dynamic.Flow direction
The air conditioning quantity of each 7 side of cold air blow-off outlet is few.
In order to slightly reduce these, there are problems, and guide plate 25ax, 25ay, 25b are arranged in pipeline 12.But institute as above
It states, the most of surface current against smooth partition board 19 of cold wind for flowing to top is dynamic, flows to the air conditioning quantity of each 7 side of cold air blow-off outlet
It is few.As a result, the air conditioning quantity blown out from each cold air blow-off outlet 7 into showroom 4 is insufficient.
As countermeasure, it is necessary to be adjusted, make against the dynamic cold wind of the surface current of partition board 19 also flow to each guide plate 25ax,
The side 25ay, 25b.Then, as shown in Figure 10, Figure 11, Figure 12, the configuration adjustment plate 25z in pipeline 12.In addition, Figure 10 is table
Show the skeleton diagram of the partial longitudinal section of main body 1.Figure 11 is the enlarged drawing of a part of Figure 10.Figure 12 indicates that adjustment plate 25z's is outer
It sees.
Adjustment plate 25z is the steel plate of "L" shaped as guide plate 25ax, 25ay, 25b, and rise part C is for example, by welding
It is fixed on the surface of partition board 19, planar portions (plate portion of screening) spaces of the D into pipeline 12 is prominent.The installation of adjustment plate 25z
Position is arranged in the opposite side of guide plate 25ax, 25ay, 25b of the opening upper limb of the cold air blow-off outlet 7 of lowest part.Lowest part
Cooling of the cold air blow-off outlet 7 on the shelf 5Z of most subordinate shown in Fig. 10 blow cold air with space.
Guide plate 25ax, 25ay, 25b are installed in the inside of back side 4a, and adjustment plate 25z is installed in the table of partition board 19
Face.The planar portions D of the planar portions B and adjustment plate 25z of guide plate 25ax, 25ay, 25b are in the state of facing each other to pipeline 12
Interior space protrudes.
As shown in the amplification expression of Figure 11, guide plate is compared in the position in the upper-lower height direction of the planar portions D of adjustment plate 25z
The position in the upper-lower height direction of the planar portions B of 25ax, 25ay, 25b is slightly higher.In addition, the planar portions D's of adjustment plate 25z is upper and lower
In the case of the position of short transverse is identical with the position in upper-lower height direction of planar portions B of guide plate 25ax, 25ay, 25b,
Wind path between adjustment plate 25z and guide plate 25ax, 25ay, 25b is narrow, and ventilation resistance is big.This is undesirable.
In the front-end edge of the front-end edge Dn and the planar portions B of guide plate 25ax, 25ay, 25b of the planar portions D of adjustment plate 25z
Between Bm, defined interval is ensured in the width direction of left and right, with the traveling of obstruction free cold wind.
The cold air for carrying out Re Jiao Change with evaporator 23 and reducing temperature rises in pipeline 12.One of the cold air of rising
Divide guide plate 25ax, 25ay, 25b of impact lowest part, thus is led to the cold air blow-off outlet 7 of lowest part.It is led to lowest part
The cold air of cold air blow-off outlet 7 blown out from the cooling of the cold air blow-off outlet 7 of the lowest part on most subordinate's shelf 5 with space.It blows
The cold air gone out cools down the commodity on the shelf 5 of most subordinate.
The remaining cold air for not flowing into the cold air blow-off outlet 7 of lowest part passes through guide plate 25ax, 25ay, 25b of lowest part
Planar portions B front-end edge Bm and adjustment plate 25z planar portions D front-end edge Dn between gap rise, while a part punching
Hit the planar portions D of adjustment plate 25z.
The cold air for impacting the planar portions D of adjustment plate 25z is closed after reducing flow velocity by the cold airflow of above-mentioned gap and rising
Stream.Cold air behind interflow is not biased towards the face of partition board 19, but also flows to the sides each guide plate 25ax, 25ay, 25b (in pipeline 12
Near centre).In this way, the cold air in pipeline 12 also expeditiously to be guided into the 2nd grade of later each cold air blow-off outlet 7 from below.
If it is considered that the position in the upper-lower height direction of the planar portions D of adjustment plate 25z than lowest part guide plate 25ax,
The low situation in the position in the upper-lower height direction of the planar portions B of 25ay, 25b, a part of head of the cold air risen through evaporator 23
The first planar portions D of impact adjustment plate 25z.The cold airflow impacted after adjustment plate 25z flow to lowest part guide plate 25ax,
Direction existing for 25ay, 25b.
In this case, the more than half of cold air flows into the cold of lowest part along guide plate 25ax, 25ay, 25b of lowest part
Air-blowing outlet 7.Certainly, the cold blast rate for being directed into gas curtain blow-off outlet 10 is reduced.Want to avoid occurring such undesirable situation,
It is necessary to the position in the upper-lower height direction of the planar portions D of adjustment plate 25z is arranged than guide plate 25ax, 25ay, 25b it is flat
The position in the upper-lower height direction of facial B is high.
Adjustment plate 25z need not be configured in each cold air blow-off outlet 7, only just enough to the configuration of the cold air blow-off outlet 7 of most subordinate
.That is, as described above, the cold air for being adjusted plate 25z is not biased towards the face of partition board 19, and the center for passing through pipeline 12 is attached
Nearly flowing, therefore do not have to adjustment plate 25z, only enough cold air can also be drawn from below with each guide plate 25ax, 25ay, 25b
Each cold air blow-off outlet 7 later to the 2nd grade.
By suitably setting the protrusion size of guide plate 25ax, 25ay, 25b of each cold air blow-off outlet 7, gas curtain can be used
The cold air of enough amounts guide gas curtain blow-off outlet 10 into.
But uniformly cooled down in order to the commodity on each shelf 5 in the showroom 4 to three faces style of opening, such as
Shown in Figure 13, it is necessary to make from the air quantity ratio that each side blowing portion 7ax, 7ay of each cold air blow-off outlet 7 is blown out from each cold air blow-off outlet
The air quantity of 7 center blowing portion 7b blowouts is more.
In order to realize the purpose, as shown in figure 12, the left and right width direction of the planar portions D of adjustment plate 25z substantially
Central portion forms recess Di.Then, the protrusion length T1's, recess Di of the front and back longitudinal direction of appropriate adjustment planar portions D is front and back
The part in addition to recess Di of the notch depth T2 of longitudinal direction, the dimension D z of the left and right width direction of recess Di, planar portions D
Dimension D x, Dy of left and right width direction.
Using this structure, as shown in figure 13, can make to blow out from each side blowing portion 7ax, 7ay of each cold air blow-off outlet 7
Air quantity it is more than the air quantity blown out from the center blowing portion 7b of each cold air blow-off outlet 7.It can generally prevent from reaching gas curtain blowout
The air conditioning quantity of mouth 10 is reduced, while can increase the air conditioning quantity blown out from each cold air blow-off outlet 7.
By the front and back depth side for suitably setting the protrusion length T1 and recess Di of the front and back longitudinal direction of planar portions D
To notch depth T2, it is not necessary to make the planar portions of the protrusion length T and guide plate 25b of the planar portions B of guide plate 25ax, 25ay
The protrusion length T of B is different.For example, if the protrusion length T's and guide plate 25b of the planar portions B of guide plate 25ax, 25ay is flat
The protrusion length T-phase of facial B is same, then guide plate 25ax, 25ay and guide plate 25b can share 1 block of plate and be bent to form.
It is shown in Figure 14 and Figure 15 in the specific example for each shelf 5 that showroom 4 configures.
