Below, utilize Fig. 1-Fig. 2 that an embodiment of refrigerator of the present invention is described.
In Fig. 2, be formed with the opening 2 that commodity storage takes out usefulness in front as the open type showcase 1 of refrigerator, and disposed the Machine Room 3 that is provided with the coolant compressor (not shown) that constitutes refrigerant cycles etc. in its underpart, and, the upper wall 8 of showcase 1, rear wall 9 and conduct are to be made of the heat-barrier material 11 that foamed synthetic resin or hard foamed polyurethane etc. constitutes with the diapire 10 in the next door of Machine Room 3.
Being provided with inner surface with this heat-barrier material 11 has the interval top board of being made by rustless metallic plates such as spraying steel plate and stainless steels 13 of appropriate intervals, fascia panel 14 and base plate 15 at interval.These are top board 13 at interval, and the space between fascia panel 14 and interval base plate 15 and the heat-barrier material 11 becomes cold air path 16.And, be provided with multilayer store shelf 18 from top to bottom in the showroom 17 that fascia panel 14 and interval base plate 15 surround as storeroom by interval top board 13.In the showroom 17 top installed in front fluorescent lamp 19, in order to illuminate 17 inside, showroom.
Dispose fan 20 in the cold air path 16 below interval base plate 15, and in the cold air path 16 at the rear (right side among the figure) of fascia panel 14, disposed tabular blade fan type cooler 21.Like this, cold air path 16 can lead to the cold gas exhausting outlet 23 that forms on the front side of interval top board 13.
This fan 20 1 rotates, and the air in the cold air path 16 just carries out forced circulation along direction of arrow air-supply.That is, the air of being sent by fan 20 flows to cooler 21 and is cooled, and further rises and be discharged in the showroom 17 from cold gas exhausting outlet 23.The cold air that blows out from cold gas exhausting outlet 23 is 17 front in the showroom, and promptly commodity storage and take out with opening 22 places and form air curtain cools off showroom 17 simultaneously.Cooled off suction inlet 24 suctions of the air of this showroom 17 from the front side formation of interval base plate 15, return fan 20 then.
Further, utilize the Fig. 1 that amplifies the A part that illustrates among Fig. 2 that cold gas exhausting outlet 23 is described now.At the front end (left end among the figure) of flat upper wall 8, be fixed with section and be L shaped laterally (among the figure for from the lining outwardly direction) elongated front baffle 31, fixing by plastic cabinet thermal insulation parts 32 in the bottom of this front baffle 31.
The cabinet external reflectance plate 33 that is formed by materials such as the steel plate that sprays, stainless steels is installed on the front, bottom of cabinet thermal insulation parts 32, on this cabinet external reflectance plate 33, has disposed fluorescent lamp 19 illustrated in fig. 2.Inside the bottom of these cabinet thermal insulation parts 32, fixing bottom as the cabinet outboard partition 40 of cabinet outer passage wall.Though this cabinet external reflectance plate 33 is warmmer, and cabinet outboard partition 40 is turned cold by the cold air cooling, but as previously mentioned, owing between cabinet external reflectance plate 33 and cabinet outboard partition 40, be provided with cabinet thermal insulation parts 32, therefore, between cabinet external reflectance plate 33 and cabinet outboard partition 40, there is not heat flow.
Cabinet outboard partition 40 carries out sheet metal processing bending by the metallic plate to the spraying steel plate of laterally-elongated or stainless steel etc. and forms.Its cross sectional shape is as follows: as described below, in order to be fixed to the inside of cabinet thermal insulation parts 32, the configuration of bottom perpendicular; Bend oblique top from this lower end and be provided with,, be bent to form the front and back width towards the cabinet outside and be about 2 millimeters to 3 millimeters step part 42 midway towards this upper wall 8 towards upper wall 8.Bending with upper wall 8 contact positions, form installation position 44 along upper wall 8 lower surfaces, and being bent to form downward direction of the traffic, the inner of installation position 44 adjusts plate 46.
By adopting this structure, because the below part of the step part 42 of cabinet outboard partition 40, it is side-prominent that promptly cold air is discharged side direction cold air path 16.And as previously mentioned, this step part 42 and direction of the traffic are adjusted plate 46 and are made for elongated metallic plate by bending laterally, therefore can be longer to horizontal extension.
At interval the front side of top board 13 (left side among the figure) bent and square neck is oblique down, thereby forms the cabinet inner channel wall 51 of cold gas exhausting outlet 23.The bottom of this cabinet inner channel wall 51 is lateral buckling in cabinet further, forms acclivitous leading section.
Between cabinet inner channel wall 51 and cabinet outboard partition 40, insert and be positioned with honeycomb fashion current equalizer (rectification Ha ニ カ system) 61.The length than cabinet inboard that the length of the unit 61a of this honeycomb fashion current equalizer 61 will be made the cabinet outside is long.In addition, the step part 42 of above-mentioned cabinet outboard partition 40 extends along the bottom in the cabinet outside of honeycomb fashion current equalizer 61, and the bottom, the cabinet outside of this honeycomb fashion current equalizer 61 is by these step part 42 location.As previously mentioned, though the front and back of this stage portion 42 wide be the 2-3 millimeter, can do suitable modification towards the direction that increases or dwindle.For the size of the unit 61a of honeycomb fashion current equalizer 61, wide smaller more good than the front and back of unit 61a, more suitable is is about its half.
The side of the cabinet inboard of honeycomb fashion current equalizer 61 is entrenched in the carriage 71 as positioner.Bonding pad 76 by axle 77 rotationally pivot suspension on this carriage 71.Be formed with in conjunction with protuberance 78 on the surface of the cabinet inboard of bonding pad 76, this protuberance 78 protrudes into the interior realization of the not shown perforate combination on the cabinet inner channel wall 51.
Thereby, when will be when cold gas exhausting outlet 23 folding removes honeycomb fashion current equalizer 61, bonding pad 76 be rotated along clockwise direction as the center with axle 77.Like this, the not shown perforate in conjunction with protuberance 78 and cabinet inner channel wall 51 of bonding pad 76 is separated and is indexed in the cold air path 16, then, downward tractive carriage 71, honeycomb fashion current equalizer 61 also just is drawn out with carriage 71.
In contrast, for will and the honeycomb fashion current equalizer 61 that is separated of cold gas exhausting outlet 23 be inserted and positioned between cabinet inner channel wall 51 and the cabinet outboard partition 40, earlier the side with the cabinet inboard of honeycomb fashion current equalizer 61 is entrenched on the carriage 71, with chimeric state the distortion of honeycomb fashion current equalizer 61 elasticities of compression and be pressed into.Be inserted into institute's allocation then always, and bonding pad 76 is against the sun rotated, make to be attached in the not shown perforate of cabinet inner channel wall 51 and locate in conjunction with protuberance 78.At this moment, the lower end of the cabinet outboard end of honeycomb fashion current equalizer 61 be positioned in cabinet outboard partition 40 step part 42 directly over the position on.In addition, because the front and back width of the cold air path 16 of the top of step part 42 is bigger than the front and back width of the cold air path 16 of its below, the state expansion from its elastic compression increases honeycomb fashion current equalizer 61 by its restoring force.
Owing to formed step part 42, honeycomb fashion current equalizer 61 must compression-expansion on loading and unloading cold gas exhausting outlet 23 time, and it is suitable making it have bigger restoring force.Thereby, compare the school with the material that forms by the bigger aluminium foil of plastic deformation, only is by synthetic resin, particularly the material of polyvinyl chloride formation.
Below, the effect of the embodiment of the refrigerator with cold gas exhausting outlet 23 of being with said structure is described.
In Fig. 2, as mentioned above, when fan 20 rotates, when being sent to cold air in the cold air path 16, in Fig. 1, cold air flow into the front side of cold air path 16 from rear side (right side Fig. 1), by the direction of the traffic of cabinet outboard partition 40 being adjusted plate 46 deflection belows, can flow into equably in the whole honeycomb fashion current equalizer 61.And under the situation of not having this direction of the traffic adjustment plate 46, cold air can flow in the front part of honeycomb fashion current equalizer 61 in large quantities.In addition, the length of the preceding side unit 61a of honeycomb fashion current equalizer 61 is longer than the length of the unit 61a of rear side, has increased the pipe resistance of front side, thereby can not flow in a large number toward cold air in the preceding side unit 61a of honeycomb fashion current equalizer 61.
Flow into cold air in the honeycomb fashion current equalizer 61 equably from flowing to the opening part 23a of cold gas exhausting outlet 23 after the below of honeycomb fashion current equalizer 61 blows out.This moment, because the pipe resistance of the cabinet outboard end unit 61b of honeycomb fashion current equalizer 61 is big, so cold air can blow out hardly as to Fig. 4 explanation of prior art.But, the blow-off outlet of the unit 61b of this cabinet outboard end faces the step part 42 of cabinet outboard partition 40, thereby, the below of step part 42, the i.e. surface of the cabinet outboard partition 40 of cold air discharge side are positioned at the cold air of the unit 61a of the complete hexagonal cells shape adjacent with unit 61b and discharge side.
Therefore, the cold air that blows out from unit 61a can flow along the surface of cabinet outboard partition 40 fully, and extraneous air then can not flow on the surface of cabinet outboard partition 40 of low temperature.And because this step part 42 is to discharge side end along the cold air of honeycomb fashion current equalizer 61 to form, therefore discharge side end along the cold air of this honeycomb fashion current equalizer 61, promptly in the scope that laterally has honeycomb fashion current equalizer 61 of cabinet outboard partition 40, cold air just can flow along the surface of cabinet outboard partition 40 fully.
As mentioned above, the step part 42 of cabinet outboard partition 40 processes by metallic plate is carried out sheet metal, therefore makes simple.
In addition, the aluminium that need not have good plastic deformation at honeycomb fashion current equalizer 61 is made, but under the situation with the fabulous synthetic resin formation of nerve, be cleaning honeycomb fashion current equalizer 61, even the opening 23a by cold gas exhausting outlet 23 loads and unloads honeycomb fashion current equalizer 61 repeatedly, honeycomb fashion current equalizer 61 can be not impaired because of plastic deformation yet.
Near the cold air of cabinet outboard partition 40 honeycomb fashion current equalizer 61 is discharged side and is formed step part 42, and near the cold air inflow side honeycomb fashion current equalizer 61 makes the extension that maintains the original state of the face that joins with honeycomb fashion current equalizer 61, and forms the cool-air feed space like this.Therefore by this cool-air feed space, cold air can successfully flow in the outer side unit 61a of cabinet of honeycomb fashion current equalizer 61.
More than describe embodiments of the invention in detail.But the present invention is not limited in the scope of the foregoing description.And in of the present invention total design scope of in the claim scope, putting down in writing, can make various improvement.Improvement embodiment of the present invention is as follows.
1. in an embodiment, form air curtain by the cold air that blows out from cold gas exhausting outlet at above-below direction, and the formation direction of this air curtain also need not be at above-below direction, the direction suitable towards horizontal direction or incline direction etc. is also passable.
2. the honeycomb fashion current equalizer releasably is positioned positioner on the cabinet inner channel wall and does not also limit the mode of record in an embodiment, as have releasably that the function of positioning honeycomb spare also can adopt other appropriate device.
3. in an embodiment,, also can adopt other suitable material and processing method though the cabinet outboard partition is to process by metallic plate is carried out sheet metal.
According to the present invention, because the cabinet outer passage wall of cold gas exhausting outlet is side-prominent to cold air path along the cold air discharge side end of honeycomb fashion current equalizer, then to discharge the part of side be not the end that is positioned at the honeycomb fashion current equalizer that blows out cold air hardly near the cold air that is positioned at the honeycomb fashion current equalizer of the cabinet outer passage wall of cold gas exhausting outlet, but the cold air that is in the part that the unit of the fast honeycomb fashion current equalizer of the cold air flow velocity that blows out is completed into is discharged side.So cold air can flow along cabinet outer passage wall, extraneous gas does not invade on the cabinet outer passage wall.Also dewfall and then become water droplet and fall of extraneous gas consequently with regard to not contacting with cabinet outer passage wall.
In addition, positioner releasably is positioned at the honeycomb fashion current equalizer on the cabinet inner channel wall, by removing location by this positioner, just can very simply the honeycomb fashion current equalizer be taken out from cold gas exhausting outlet, just can the honeycomb fashion current equalizer cleaning of taking out is clean.
In order to prevent aforesaid frosting problem, the cabinet outer passage wall of cold gas exhausting outlet is side-prominent to cold air path, utilizes because of outstanding formed step part, with the cabinet outboard end location of honeycomb fashion current equalizer.Therefore, the cabinet medial end of honeycomb fashion current equalizer and cabinet outboard end are located by the step part of positioner and cabinet outer passage wall respectively.
The result is by in the cantilever support that adopts in the existing cold gas exhausting outlet as shown in Figure 3, and the position skew can appear in the cabinet outboard end of honeycomb fashion current equalizer, therefore the honeycomb fashion current equalizer can not be positioned on the position of design; And according to the present invention, the cabinet medial end of honeycomb fashion current equalizer is located by positioner, and the cabinet outboard end is positioned at the position of design by above-mentioned step part simultaneously, thereby can guarantee the only wind speed profile of air curtain, can guarantee good cooling performance again.
