The specific embodiment
Please in conjunction with Fig. 1 and Fig. 2 referring to Fig. 3 and shown in Figure 4, the open freezing and refrigeration combination showcase of air curtain apparatus is folded mutually up and down by Over-The-Counter 10 and following cabinet 20 and is formed in the middle of the utility model band.
Over-The-Counter 10 has the Over-The-Counter air channel 11 that cross section is " " word shape, and the air outlet 111 in Over-The-Counter air channel 11 is arranged on the last front end in " " font Over-The-Counter air channel 11 with being that Open Side Down; Return air inlet 112 openings in Over-The-Counter air channel 11 up are arranged on the lower front end in " " font Over-The-Counter air channel 11; Cold air is sent downwards after advancing to air outlet 111 places, Over-The-Counter air channel along Over-The-Counter air channel 11, forms the air curtain 12 that intercepts Over-The-Counter 10 internal-external heat exchange.This air curtain 12 is sucked back in the Over-The-Counter air channel 11 by the return air inlet 112 in Over-The-Counter air channel 11, continues the circulation air curtain 12 that circulation also forms Over-The-Counter once more.
Following cabinet 20 has the following cabinet air channel 21 that cross section is " recessed " word shape, and the air outlet 211 in following cabinet air channel 21 is the upper right side that opening is arranged on cabinet air channel 21 under " recessed " font left; The return air inlet 212 in following cabinet air channel 21 is the left-hand end that opening up is arranged on cabinet air channel 21 under " recessed " font; Cold air is sent forward after cabinet air channel 21 advances to down cabinet ducting outlet 211 places down, the air curtain 22 of cabinet 20 internal-external heat exchange under the upper surface formation of cabinet 20 intercepts down.The windshield 23 of cabinet 20 front portions blocks under these air curtain 22 quilts, and the return air inlet 212 in cabinet air channel 21 sucks back down in the cabinet air channel 21 under the quilt, the circulation air curtain 22 of cabinet under the formation once more that continues to circulate also.
Upset the circulation air curtain 22 of following cabinet 20 in the cabinet 20 and cause down the load of cabinet 20 to increase in order to stop the cold air that overflows in the Over-The-Counter 10 to enter down, and refrigerating capacity obviously strengthens and the generation of the phenomenon of continuation severe exacerbation, in the utility model, between Over-The-Counter 10 and following cabinet 20 air curtain apparatus 30 in the middle of is set, this centre air curtain apparatus 30 is made up of middle air channel 31 and the fan 32 that is arranged in the air channel 31, centre; Intercept the isolated air curtain in centre that air-flow mixes between Over-The-Counter 10 and the following cabinet 20 in order to form, and then stop the cold air that Over-The-Counter 10 overflows to enter down in the cabinet 20, thereby guarantee that cabinet 20 can keep predetermined in-cabinet temperature down.
Air curtain apparatus 30 can be arranged between Over-The-Counter 10 and the following cabinet 20 in the middle of described, and in the present embodiment, described middle air curtain apparatus 30 is arranged on down the position, upper end of cabinet 20.
In the present embodiment, the middle air channel 31 in the middle air curtain apparatus 30 is the positions, upper end that are horizontally installed on down cabinet 20, promptly is positioned at the top of cabinet air channel 21 outlets 211 down; Fan 32 in the middle air curtain apparatus 30 is arranged in the horizontal middle air channel 31; The preferable position of air channel 31 fans 32 is oblique upper ends that are arranged on down cabinet air channel air outlet 211 in the middle of being arranged in; Middle air channel 31 is interlinked to the outside (not shown) with cabinet by fan 32 and obtains to suck air-flow.The air outlet 311 in middle air channel 31 is positioned at the downside of Over-The-Counter return air inlet 112.
In the present embodiment, in order effectively to stop the cold air that Over-The-Counter 10 overflows to enter down in the cabinet 20, form certain angle between air outlet 311 parts in middle air channel 31 and the return air inlet 112 in Over-The-Counter air channel 11, make between air outlet 311 parts and the horizontal plane and form acute angle, angular range is 0 °～85 °, and the fan 32 in the middle air channel 31 is the oblique upper ends that are arranged on down cabinet air channel air outlet 211, air outlet 311 part equidirectional ground with middle air channel 31, therefore the isolated air curtain 33 in the centre that air channel 31 is sent in the middle of makes progress and outwards oblique extending out along the angular range with 0 °～85 ° between formation of middle air channel air outlet 311 directions and the horizontal plane, therefore the middle air curtain 33 that blows out with this angle can intercept the cold air that overflows in the Over-The-Counter 10 effectively, it can't be invaded down in the cabinet 20 go;
In the present embodiment, the middle air curtain 33 that blows out for the air outlet 311 that makes middle air channel 31 reaches the certain cold air of wind speed to overflow in effective obstruct Over-The-Counter 10, the width of the air outlet 311 in air channel 31 can not be too wide in the middle of requiring, and the width of usually middle air channel 31 outlets 311 is set between 1 millimeter to 10 millimeters; Yet, for bigger open freezing and refrigeration combination showcase or combination down in the cabinet 20 content of display many and when requiring the low situation of freezing and refrigeration temperature, the optimum width of middle air channel 31 outlets 311 is 3～6 millimeter, the air-out speed in middle air channel can be controlled at like this in the scope quite at a high speed, formation can effectively completely cut off the isolated air curtain 33 in centre of cabinet air-flow exchange up and down, stop the cold air that overflows in the Over-The-Counter to enter down cabinet, reduce the increase of cabinet refrigeration load down, thereby reach effective control the temperature of open freezing and refrigeration combination showcase.
In sum, in the middle of the utility model band the open-type refrigeration cold-storage of air curtain apparatus combination showcase because At the middle air curtain apparatus of being provided with between the cabinet up and down of combination showcase, form the isolated up and down gas between the cabinet of one deck Therefore the isolated air curtain in the centre that stream mixes can stop the cold air that overflows in the Over-The-Counter to enter in the lower cabinet, makes lower cabinet energy Maintain in-cabinet temperature; Simultaneously, because the air outlet in middle air channel is arranged to and horizontal plane between angle Be acute angle, simultaneously with fan also oblique setting, therefore, the middle air curtain of from middle air channel, sending also with water Form acute angle between the plane. And, because the air outlet width in middle air channel is arranged on 1 to 10 millimeter Between, make thus the middle air curtain that blows out from this air outlet have quite high speed, and formation and level The acutangulate isolated up and down isolated air curtain of air-flow between the cabinet of face, this centre with proper angle and wind speed Air curtain can stop the cold air that overflows in the Over-The-Counter to invade lower cabinet and upset lower cabinet air curtain effectively, thereby plays stable Lower cabinet load and keep the effect of lower cabinet normal temperature is to the freshness of guaranteeing display goods with reduce the energy and disappear Consuming highly beneficially, is a very fresh-keeping power-saving technology of showcase of Nover practical, therefore very practical.
