As shown in fig. 1 to 11, the present invention provides a vertical refrigerator for commercial use, comprising: cabinet body 1, refrigeration circuit, centrifugal fan 3 and wind channel apron 4.
The cabinet body 1 comprises a shell 11 and an inner container 12, the inner container 12 is arranged in the shell 11, and a heat insulation layer is formed between the inner container 12 and the shell 11. The refrigeration circuit comprises a compressor (not shown), a condenser (not shown), a throttling device (not shown) and an evaporator 2 connected together. The centrifugal fan 3 comprises a volute 31 and a centrifugal fan 32, wherein the front surface of the volute 31 forms an air suction opening 301, the lower part of the volute 31 forms an air discharge opening 302, and the centrifugal fan 32 is positioned in the volute 31; an air inlet 401 and an air outlet 402 are arranged on the air duct cover plate 4, and the air inlet 401 is positioned above the air outlet 402. The air duct cover plate 4 is arranged in the inner container 12 and forms an air duct 100 with the back of the inner container 12, the area of the inner container 12 located on the front side of the air duct cover plate 4 forms a storage cavity, the centrifugal fan 3 and the evaporator 2 are located in the air duct, an air inlet area is formed between the volute 31 and the air duct cover plate 4, and the air inlet 401 and the air suction opening 301 are arranged oppositely.
In the actual operation process of the refrigerator, a refrigerant in the refrigeration loop circularly flows under the action of the compressor and is refrigerated through the evaporator 2. Air in the inner container 12 circularly flows at the front side and the rear side of the air duct cover plate 4 under the action of the centrifugal fan 3, so that the air in the inner container 12 is cooled after heat exchange through the evaporator 2. The process of the refrigerant circulating flow of the refrigeration circuit and the working process of the centrifugal fan 3 are not limited and described herein.
In order to effectively increase the volume of the storage cavity in the inner container 12, the upper and lower spaces of the inner container 12 may be optimized correspondingly, which is specifically described with reference to the accompanying drawings.
In the first embodiment, the upper space of the inner container 12 is optimally designed, and the volume of the storage cavity in the inner container 12 is increased by reducing the distance between the air duct cover plate 4 and the volute casing 31. Specifically, since the air suction opening 301 of the centrifugal fan 3 faces the air duct cover plate 4, in order to meet the air intake requirement of the centrifugal fan 3, a sufficient distance needs to be set between the air duct cover plate 4 and the volute casing 31 to meet the air intake requirement, so that the upper storage space of the inner container 12 is reduced. For this purpose, an auxiliary air inlet 403 communicating with the air duct is formed between the top of the air duct cover 4 and the top wall of the inner container 12.
During the operation of the centrifugal fan 3, air in the storage cavity in the inner container 12 enters the air inlet area through the air inlet 401 and the auxiliary air inlet 403 respectively. Air introduced from the air inlet 401 directly enters the scroll casing 31 through the air suction hole, and air sucked from the auxiliary air inlet 403 enters the scroll casing 31 from the periphery of the air suction hole. Thus, the amount of air entering the air intake area can be increased through the auxiliary air inlet 403, and the distance between the air duct cover plate 4 and the volute casing 31 can be reduced on the premise of meeting the air intake amount, so that the storage space in the upper area of the inner container 12 can be increased.
In some embodiments, in order to enable the auxiliary air inlet 403 to suck air from the front region of the inner container 12 to accelerate the air circulation flow speed in the inner container 12, the top of the air duct cover 4 is further provided with a top cover 43 extending toward the front side of the cabinet 1, and a return air channel (not labeled) communicating with the air duct is formed between the top cover 43 and the top wall of the inner container 12. The return air duct can extend from the top of the inner container 12 to the front region of the inner container 12, and air in the front region of the inner container 12 can be sucked in by the return air duct when the centrifugal fan 3 is in operation. Therefore, the air in the storage cavity in the inner container 12 can flow more uniformly and circularly, and the air in the inner container 12 can flow more quickly.
Further, a plurality of air deflectors 44 are disposed on the top cover plate 43 in a longitudinal direction. Specifically, the air deflector 44 can guide the airflow entering the return air channel, so that the airflow can be uniformly dispersed to the periphery of the air suction opening 301, and a larger air suction amount is ensured.
Preferably, the rear end of the air deflector 44 extends backwards to the outside of the air duct cover plate 4, and the rear end of the air deflector 44 is further provided with a positioning plate 45, and the positioning plate 45 abuts against the volute casing 31. Specifically, when assembling, the positioning plate 45 can abut against the volute casing 31, so as to conveniently assemble the air duct cover plate 4 into the inner container 12 and accurately position and fix the air duct cover plate. The positioning plate 45 is disposed above the air inlet 301, so that an air guide channel (not labeled) for guiding air toward the air inlet 301 is formed between the positioning plate 45 and the back of the air duct cover plate 4, and the air flow output from the air return channel is guided to the air inlet 301 below through the air guide channel.
In other embodiments, the duct cover 4 includes: an upper cover plate 41 and a lower cover plate 42. Wherein, an air inlet 401 is formed on the upper cover plate 41, and an air outlet 402 is formed on the lower cover plate 42; the upper cover plate 41 is located above the lower cover plate 42, the lower edge of the upper cover plate 41 is butted with the upper edge of the lower cover plate 42, the upper cover plate 41 is located opposite to the front side of the scroll casing 31, and the lower cover plate 42 is located on the front side of the evaporator 2. Specifically, the air duct cover plate 4 is of a split structure, the upper cover plate 41 covers the centrifugal fan 3, and the lower cover plate 42 covers the evaporator 2. The connection manner of the upper cover plate 41 and the lower cover plate 42 may be a splicing manner, which is not limited and described herein.
In some embodiments, the two sides of the upper cover plate 41 are provided with flange structures 411 extending towards the rear side of the cabinet 1, and the flange structures abut against the back of the inner container 12. Specifically, the flanging structure 411 abuts against the inner container 12 and can shield both sides of the centrifugal fan 3. Preferably, an interval is formed between the flanging structure and the side wall of the inner container 12, the flanging structure is further provided with a vent hole 412 communicated with the air duct, and the vent hole 412 can also realize that air on two sides of the top of the inner container 12 enters an air inlet area and is sucked into the volute casing 31 through the air suction opening 301. Thus, the air intake can be further increased to meet the requirement of setting a small distance between the volute casing 31 and the air duct cover 4.
In a preferred embodiment, the back surface of the upper cover plate 41 is provided with a partition 413, and the partition 413 is transversely arranged below the air inlet 401 and abuts against the volute casing 31. Specifically, after the centrifugal fan 3, the evaporator 2 and the duct cover 4 are assembled in the inner container 12, the partition 413 abuts against the scroll casing 31, and the air outlet 302 is separated from the above air inlet and air inlet by the partition 413, so that the air output from the air outlet 302 is blown directly to the evaporator 2. Further, the reverse flow of the air flow output from the air outlet 302 to the air inlet area due to the blockage of the evaporator 2 can be avoided or reduced, and the heat exchange efficiency is improved.
In another embodiment, in order to increase the volume of the storage cavity of the inner container 12 to a greater extent, the back of the inner container 12 is further provided with an outward protruding portion 121, the outward protruding portion 121 forms a mounting groove in the inner container 12, and the centrifugal fan 3 and the evaporator 2 are disposed in the mounting groove. Specifically, the back of the inner container 12 is formed with an outward protrusion 121 protruding toward the housing 11, so as to further increase the internal volume of the inner container 12, and the centrifugal fan 3 and the evaporator 2 are mounted in the mounting groove formed by the outward protrusion 121, so as to maximally increase the volume of the storage cavity in the inner container 12.
Through forming the auxiliary air import between wind channel apron and the inner bag top, the air intake air on the wind channel apron can be cooperated in the auxiliary air import to satisfy the requirement of intake, like this, alright in order to make the wind channel apron further reduce with the distance between the spiral case, thereby reserve bigger space at the top of inner bag and come the storage article, increased the whole storing space of inner bag on the whole.
In the second embodiment, the lower space of the inner container 12 is optimally designed, and the volume of the storage cavity in the inner container 12 is increased by reducing the overall height dimension of the air duct cover plate 4 and arranging the air duct cover plate 4 in the upper region of the inner container 12. Specifically, a storage space is formed between the lower part of the air duct cover plate 4 and the bottom of the inner container 12. The commercial vertical refrigerator also comprises a water receiving tray 5, and a drainage part 50 for draining water outwards is arranged on the water receiving tray 5; wherein, the water pan 5 is arranged on the back of the air duct cover plate 4 and is positioned below the evaporator 2.
In actual use, the centrifugal fan 3 and the evaporator 2 are installed by forming an air duct on the upper back area of the inner container 12 through the air duct cover plate 4. Thus, a space can be reserved in the lower area of the inner container 12 for placing articles, so that the volume of the storage cavity in the inner container 12 is increased by utilizing the area at the lower part of the air duct cover plate 4.
Because the air duct cover plate 4 does not completely cover the back of the inner container 12, in order to meet the defrosting requirement of the evaporator 2, correspondingly, the water receiving tray 5 is arranged on the back of the air duct cover plate 4, when the evaporator 2 defrosts, defrosted water drops into the water receiving tray 5, and partial defrosted water flows into the water receiving tray 5 along the air duct cover plate 4, so that the phenomenon that the defrosted water flows randomly in the inner container 12 is avoided. The defrosted water collected in the drain pan 5 is finally discharged uniformly through the drain unit 50.
In some embodiments, the drip tray 5 comprises: an upper tray body 51, a lower tray body 52 and a support plate 53. An upper water collecting tank 511 is formed on the upper tray body 51, and a lower water collecting tank 521 is formed on the lower tray body 52; a plurality of supporting plates 53 are arranged between the upper tray body 51 and the lower tray body 52, an air outlet interval 50 is formed between two adjacent supporting plates 53, a connecting flow passage 54 is further arranged between the upper water collecting tank 511 and the lower water collecting tank 521, and an auxiliary air outlet 404 is formed between the lower part of the air duct cover plate 4 and the back of the inner container 12.
Specifically, for the upper tray body 51, the edge of the upper tray body 51 will abut against the back of the air duct cover plate 4, so that the defrosting water dropping from the evaporator 2 and flowing down from the air duct cover plate 4 can be collected by the upper tray body 51. Meanwhile, as for the lower tray body 52, the edge of the lower tray body 52 is attached to the back of the inner container 12, and the defrosting water dropping from the evaporator 2 and flowing down from the inner container 12 can be collected through the lower tray body 52. Further, the upper tray body 51 and the lower tray body 52 are arranged in a staggered manner from front to back, and the vertical projection of the upper tray body 51 and the vertical projection of the lower tray body 52 form an overlapping area, so that the defrosting water dropping from the evaporator 2 can be prevented from being missed.

Similarly, the defrosting water in the water receiving tray 5 may be discharged by using a drain pipe, that is, the drain part 50 is a drain pipe communicated with the lower water collecting tank 521, and the drain pipe is disposed at the back of the inner container 12.
In some embodiments, the back surface of the duct cover plate 4 is further provided with a raised water retaining rib 421, and the edge of the upper disc body 51 abuts against the lower side of the water retaining rib 421. Specifically, the defrosting water flows downwards along the back surface of the air duct cover plate 4 and is blocked by the water blocking ribs 421, so that the defrosting water flows into the upper tray body 51 after passing through the water blocking ribs 421. And the structural style that the upper disc body 51 is arranged obliquely downwards is matched, the phenomenon that the defrosting water flows down along the back surface of the air duct cover plate 4 and directly drops in the inner container 12 can be reduced or avoided, and the user experience is improved.
