Description
Technical field
The invention belongs to refrigerator technical field, specifically, relate to the air-supply of a kind of refrigerator and refrigeration system and refrigerator.
Background technology
The medical cupboard that Medical Devices use adopts refrigerator usually, and the air-supply in current refrigerator and refrigeration system mainly comprise blower fan, evaporimeter and inside and outside two-layer cover (as illustrated in fig. 1 and 2), and inner cover is installed blower fan, served as water spilage tray simultaneously.There is following shortcoming in this air-supply and refrigerant system configurations:
1) inner cover inner space is large, and in the case sucked by blower fan, air cannot completely by evaporimeter, and most of air-flow is passed by the side of evaporimeter and bottom surface, effectively do not cooled, and air-flow is unstable, the operating efficiency of the reaction force reduction fan blade of generation.Reduce the operating efficiency of medical cupboard entirety.
2) evaporimeter water spilage tray and blower fan are in the same space, and condensed water (condensation) is not exclusively separated with blower fan electrical part, easily produces hidden danger.
3) separately, volume is large, takies space in case for water spilage tray and outer cover, increases cost.
4) because volume of part is large, easily produce distortion, cause outer layer cover unsightly and impact assembling, produce vibration and noise.
5) water spilage tray, blower hood volume weight are all comparatively large, and need first semifixed inner cover (water spilage tray) then in narrow space, to connect electricity piece, finally just can be completely fixed, and install difficulty and cabling cannot be completely fixed.
For the above-mentioned series of problems that the air-supply in current refrigerator and refrigeration system exist, invention has been effective improvement.
Summary of the invention
The object of the invention is for solve air-flow in refrigerator inabundant by evaporimeter, cause heat exchange efficiency lower, evaporimeter and electricity piece do not separate the problem that potential safety hazard and system install difficulty, and provide a kind of refrigerator to blow and refrigeration system and refrigerator.
For solving the problems of the technologies described above, on the one hand, the invention provides the air-supply of a kind of refrigerator and refrigeration system, comprise liner top plate, plate after inner bag, evaporimeter and blower fan, described evaporimeter is fixedly installed in described liner top plate, after described inner bag, plate is provided with rear air channel, described evaporimeter bottom arranges water spilage tray, described water spilage tray both sides parcel evaporimeter is also connected with liner top plate, the front side of described water spilage tray arranges fan supporter, with described rear air channel UNICOM on rear side of described water spilage tray, described blower fan is arranged on fan supporter, described water spilage tray and fan supporter are separate parts or have independently space respectively, form with described rear air channel the ventilating duct sealed after described water spilage tray and fan supporter overlap mutually.
The present invention propose air-supply and refrigeration system in ventilating duct, stable air-flow can be merged into, namely the wind blown out by blower fan through evaporimeter along ventilating duct major part, then enters freezer liner inside by the cold air of evaporimeter along ventilating duct major part, substantially increases heat exchange efficiency.And drip tray and fan supporter have independently space, the electricity piece of condensed water and blower fan side is completely cut off, and water power separately, avoids potential safety hazard.
Further, described water spilage tray and fan supporter are separate parts, and described water spilage tray comprises chassis, the left and right sides, described chassis is provided with the rib for both sides parcel evaporimeter, chassis upper surface is provided with fuisw rib, and arrange turnup structure on front side of described chassis, rear side arranges air guide member.
Wherein, described fuisw rib comprises two, is funneling arrangement along air-flow direction.
Wherein, described air guide member is the long strip-board shape structure arranged along described drip tray edge direction, which is provided with the breach corresponding with described rear air channel number, single rear air channel openings of sizes.
Wherein, described turnup structure comprises the vertical edge being arranged on upper overturning in the middle part of drip tray leading edge and upper overturning both sides, the rib of described vertical edge and water spilage tray is contour, described vertical edge side is docked with described rib, opposite side arranges in-flanges, the top of described vertical edge and the top of rib all arrange flanging, and described flanging is provided with screw hole, and described screw hole is for being fixed on described liner top plate through screw by described water spilage tray.
Further, described water spilage tray and fan supporter are separate parts, described fan supporter comprises chassis and three ribs, described three ribs lay respectively at the left and right sides and the front side on chassis, described chassis is arranged assembling hole, the top of described rib is provided with flanging, and described flanging is provided with screw hole, and described screw hole is for being fixed on described liner top plate through screw by described fan supporter.
Wherein, be provided with bridging arrangement on rear side of the chassis of described fan supporter, described bridging arrangement comprises upper overturning, and the top central authorities of this upper overturning are provided with rear flange, and described bridging arrangement overlaps with the turnup structure of water spilage tray and coordinates.
Wherein, the position in corresponding described assembling hole, the bottom of described fan supporter is provided with wind scooper.
Wherein, the upper overturning of described water spilage tray and the contour setting of the upper overturning of fan supporter are highly 8-10mm.Arranging of upper overturning places condensation flow in fan supporter, and the rear flange on fan supporter rides on the upper overturning of water spilage tray, prevents air-flow to run off, and the height of upper overturning can not be too high, passes through in case block air-flow.
On the other hand, present invention also offers a kind of refrigerator, the air-supply adopting the present invention above-mentioned and refrigeration system.
The phenomenon that the air-flow that the blower fan that the present invention is directed to current air-supply and refrigeration system existence sucks is not effectively cooled, first consider the air-flow that blower fan produces to put together as far as possible pass through evaporimeter completely, secondly for the phenomenon that water power is not separated, need evaporimeter and blower fan electrical part to separate, so need to increase in former inner cover inside cut off or former interior fan housing is divided into two independently area of space.Simultaneously in order to solve the problem of installing difficulty, former interior fan housing being changed into split type, installing like this and will facilitate a lot, fan housing profile can be improved simultaneously, improving aesthetics.
