Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to a refrigeration equipment structure with an air duct structure placed on top. Background Art

[0002] Existing refrigeration equipment such as refrigerated display cabinets generally adopt an axial flow fan structure, and the axial flow fan is also assembled and arranged at the top position of the refrigerated display cabinet during assembly.

[0003] Since the axial flow fan has an axial air inlet and axial air outlet structure, in order to ensure a good cooling effect, the axial flow fan needs to be arranged at an angle during installation. The axis of the fan is arranged at an angle, which occupies a large space.

[0004] Moreover, after the axial flow fan is tilted as a whole, the fan cover used to shield it also needs to be tilted accordingly to ensure sufficient spacing between it and the axial flow fan and to adapt to the tilted installation method of the axial flow fan. The entire refrigeration air duct and the tilted fan arrangement will occupy a large amount of storage space in the storage room.

[0005] Since the fan requires a large space for installation, the size of the top refrigeration structure is large, which reduces the usable space inside the box. When the air is introduced, the air is directly sucked into the axial flow fan from the air inlet, and a low-pressure area is easily formed around the air inlet, so that the air around it is first sucked into the evaporator for heat exchange, while the air in other areas is lagging behind in the heat exchange, and finally the temperature in the storage room is uneven due to uneven air supply.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field.

[0077] The utility model provides an embodiment of a refrigeration device, referring to Figure 1-Figure 2 As shown, including:

[0078] The box body 100 includes an inner liner component, and a storage chamber is defined in the inner liner component;

[0079] The inner liner component includes an inner liner top component 110;

[0080] The inner tank side member is used to form the side wall of the inner tank component;

[0081] And the liner back plate 120 is used to form the rear wall of the liner component.

[0082] In some embodiments of the present application, the inner liner top component 110 includes: a top main body portion 111 and a folded side portion 112 folded downward from the top main body portion 111 .

[0083] The top main body portion 111 is arranged horizontally to form the top wall of the inner container, and the folded side edge portion 112 is mainly used to connect related components after being folded downward.

[0084] In some embodiments of the present application, the box body 100 includes a box shell, which constitutes the outer shell of the box body 100 .

[0085] Cabinet module 200, see Figure 3 As shown, it is arranged at the front end of the storage room and connected to the box body 100;

[0086] The front-to-back direction in this embodiment refers to when the refrigeration device is normally placed for use, with the side facing the user being the front and the opposite being the rear. The front-to-back direction corresponds to the depth placement of the refrigeration device, and the width direction corresponds to the left-right direction thereof.

[0087] In some embodiments of the present application, the cabinet opening module 200 includes: a cabinet opening body member 210 and a cabinet front beam member 220 connected to the cabinet opening body member.

[0088] The cabinet opening body is an injection molded part, and an insertion opening is provided on the cabinet opening body. The folded side edge portion 112 located on one side of the top main body portion 111 is bent and inserted into the insertion opening to be plugged and fixed to the inner tank top component 110.

[0089] The folded side portion 112 on the other side of the top main body portion 111 is bent downward to connect with the inner container rear plate 120 .

[0090] The cabinet front beam 220 is plugged and fixed to the cabinet body 210, and the top of the cabinet front beam 220 is connected to the top plate of the box shell.

[0091] A closed foaming cavity is formed between the cabinet opening front beam member 220, the cabinet opening body member 210, the liner member and the box shell, and the foaming cavity is filled with a heat-insulating foaming material.

[0092] The air duct component 300 is assembled and fixed on the inner liner top member 110, and an air duct is formed between the inner liner top member 110, wherein the air duct has a first air inlet portion;

[0093] The air duct component is buckled on the inner liner top component 110 and connected to the inner liner top component 110 to form an air duct, and the first air inlet portion is a first air inlet formed on the air duct to facilitate the airflow in the storage room to enter the interior of the air duct.

[0094] The air duct also has an air duct outlet portion for sending the airflow in the air duct outwards.

[0095] The centrifugal air supply device 510 is arranged horizontally, assembled on the top wall of the inner tank, and arranged inside the air duct.

[0096] In some embodiments of the present application, the centrifugal air supply device 510 is a centrifugal fan, which can achieve axial air intake and radial air outlet effects. The centrifugal air supply device 510 is arranged corresponding to the position of the first air inlet to ensure a large air intake amount.

[0097] During assembly and fixing, the centrifugal air supply device 510 can be directly assembled and fixed on the inner tank top component 110 .

[0098] The refrigeration equipment replaces the existing axial flow fan with a centrifugal air supply device 510 by replacing the fan used for the refrigeration cycle. Since the centrifugal air supply device 510 has axial air intake and radial air exhaust, it can be horizontally arranged on the top component 110 of the inner tank when it is arranged, and its axial direction extends along the vertical direction. When taking in air, it takes in air axially and exhausts air horizontally from the other side.

[0099] Compared with the horizontal arrangement of the centrifugal air supply device 510 instead of the inclined arrangement of the axial flow fan, the storage space occupied by the storage room is reduced.

[0100] The air duct cover plate 400 is horizontally arranged below the air duct component 300 and connected to the air duct component 300 and the inner tank top member 110, and a plurality of second air inlet portions 410 evenly distributed over the air duct cover plate 400 are formed above the air duct cover plate 400;

[0101] In some embodiments of the present application, the air duct cover plate 400 is used to cover the air duct component 300 to form an external decorative plate of the entire air duct. When the user looks from the outside, he can only see the horizontally arranged air duct cover plate 400. Figure 4 shown.

[0102] Since the centrifugal air supply device 510 is arranged horizontally, in order to adapt and install it therewith, the air duct cover plate 400 is also arranged horizontally accordingly, and its bottom surface is arranged parallel to the horizontal plane.

[0103] The horizontal arrangement of the air duct cover plate 400 can further reduce the occupation of the internal space of the storage room, and further increase the storage space of the storage room.

[0104] In some embodiments of the present application, the second air inlet portion 410 is a second air inlet hole evenly distributed on the air duct cover plate 400, and the second air inlet hole can be in a circular, square or elliptical shape.

[0105] The second air inlet holes face the storage chamber and are evenly distributed on the air duct cover plate 400 , so that the airflow sucked from the storage chamber can flow in evenly through the plurality of second air inlet holes.

[0106] In order to ensure the air intake area, a plurality of second air intake portions 410 are arranged along the width direction of the box body 100 to ensure that the airflow in each area of ​​the storage room can be sucked in.

[0107] A low-pressure air inlet area is formed between the air duct cover plate 400 and the air duct component 300, and the air inlet area is connected to the first air inlet portion 333 and the second air inlet portion 410;

[0108] The air inlet area is communicated with the first air inlet portion 333 and the second air inlet portion 410 respectively, so that the airflow entering from the second air inlet portion 410 can enter the second air inlet portion 410 through the air inlet area, so that the airflow enters the air duct.

[0109] During arrangement, the air duct cover plate 400 and the bottom of the air duct component 300 are arranged at a certain distance, so that the air inlet area is formed between the air duct cover plate 400 and the air duct component 300 after assembly.

[0110] If the air duct cover plate 400 is not provided, and only the air duct component 300 and the first air inlet arranged on the air duct component 300 are provided, when the centrifugal air supply device 510 is working, the air flow will be sucked into the inside of the air duct through the first air inlet. At this time, a low-pressure area will be formed at the periphery of the first air inlet, and most of the sucked air flow is in the air flow in the periphery of the first air inlet. The air flow located in the periphery of the first air inlet is first sucked in for heat exchange, and the air flow in the remaining areas is subsequently sucked in by the first air inlet for a heat exchange cycle. There is a time difference in the heat exchange of the air flow in the storage chamber, and ultimately the temperature in the entire storage chamber is uneven due to the uneven air flow suction.

[0111] In the refrigeration device of the present embodiment, a certain distance is set between the air duct cover plate 400 and the air duct component 300 to form a low-pressure air inlet area therebetween.

[0112] When entering, the air flow first passes through multiple second air inlets 410 evenly arranged on the air duct cover 400. Through the arrangement of multiple second air inlets 410, the air flow can be evenly sucked into the air inlet area between the air duct cover 400 and the air duct component 300, so that the air inlet area corresponding to the air inlet side of the centrifugal air supply device 510 is all a low-pressure area, rather than just the area around the first air inlet of the centrifugal air supply device 510 being a low-pressure area. In this way, the air flow sucked into the centrifugal air supply device 510 is no longer the air flow at the periphery of the first air inlet, but the air flow at all positions in the inlet pressure area can be sucked into the inside of the air duct, thereby ensuring the uniformity of the air flow suction, and then also ensuring the uniformity of the temperature in the entire storage room.

[0113] The evaporator 520 is mounted on the top wall of the inner tank and arranged horizontally;

[0114] In some embodiments of the present application, the evaporator 520 is formed by bending an aluminum plate and is arranged at the air outlet 541 of the air duct to ensure that the airflow blown out from the centrifugal air supply device 510 can be directly blown above it for heat exchange.

[0115] By arranging the evaporator 520 horizontally, the storage space occupied by the evaporator 520 can be reduced. Figure 5-Figure 6 shown.

[0116] The water receiving component 530 is used to receive the condensed water on the evaporator 520, and is assembled on the inner liner component to form an evaporation chamber 540 between the inner liner component, and the evaporation chamber 540 is connected to the air duct, and the evaporation chamber 540 has an air outlet 541 connected to the storage chamber.

[0117] The water receiving component 530 is arranged below the evaporator 520 , and the condensed water dripping from the evaporator 520 can be received by the water receiving component 530 .

[0118] The water receiving component 530 is fixed on the inner liner component to form an evaporation chamber 540 together with the inner liner component. The evaporation chamber 540 can be used to accommodate the evaporator 520 to shield the evaporator 520. The evaporator 520 structure cannot be seen from the outside, and the overall aesthetics is good.

[0119] The evaporation chamber 540 is arranged to be interconnected with the air duct, so as to ensure that the airflow flowing out of the air duct can enter the evaporation chamber 540 to exchange heat with the evaporator 520 in the evaporation chamber 540 .

[0120] The air outlet portion 541 is an air outlet formed on the evaporation chamber 540 , and is used to send the airflow after heat exchange with the evaporator 520 into the storage chamber.

[0121] When the refrigeration equipment is working, the centrifugal air supply device 510 is operated to suck the air from the storage chamber into the air inlet area through the second air inlet 410, and then enters the inside of the air duct through the air inlet area. The air flow entering the air duct is blown from the air outlet 541 of the air duct to the evaporator 520 located on one side thereof by the action of the centrifugal air supply device 510. The air flow passes through the evaporator 520 for heat exchange, and the air flow after heat exchange is sent from the air outlet 541 to the storage chamber, completing a cycle.

[0122] The refrigeration equipment structure replaces the axial flow fan with a centrifugal air supply device 510, and the centrifugal air supply device 510 is arranged horizontally, and the air duct cover plate 400 matched therewith is also arranged horizontally, and the evaporator 520 is also arranged horizontally. The entire air duct fan and the evaporator 520 are arranged horizontally, which reduces the occupation of the internal space in the storage room and increases the internal space of the storage room;

[0123] At the same time, the air duct structure is improved to form a uniform low-pressure air inlet area between the air duct component 300 and the air duct cover plate 400, thereby ensuring that the airflow in the storage room can be uniformly sucked into the air duct for heat exchange, ensuring the uniformity of airflow suction, and thereby improving the uniformity of the temperature inside the storage room.

[0124] In some embodiments of the present application, a plurality of centrifugal air supply devices 510 are provided. Figure 5 As shown, one evaporator 520 is provided, and a plurality of centrifugal air supply devices 510 are arranged side by side at equal intervals along the width direction of the box body 100. By providing a plurality of centrifugal air supply devices 510, a large amount of airflow can be sucked in at one time, and air can be supplied to the evaporator 520 at the same time, thereby improving the heat exchange efficiency.

[0125] The evaporator 520 and the centrifugal air supply device 510 are arranged side by side along the depth direction of the box body 100. The centrifugal air supply device 510 is arranged near the front end of the box body 100. The first air inlet and the second air inlet 410 are arranged below the centrifugal air supply device 510 and near the front end of the box body 100. The evaporator 520 is arranged near the rear end of the box body 100, and the air outlet is also arranged at the rear end of the box body 100 accordingly.

[0126] The air flow is sucked in from the front end of the storage chamber through the centrifugal air supply device 510, enters the air duct and the evaporation chamber 540, and then enters the storage chamber from the air outlet 541 at the rear side for circulation.

[0133] The air duct baffle 320 is disposed perpendicularly to the air duct inner component 330 and the inner liner top component 110 , and one end thereof extends to the connecting component 310 and is located above the connecting component 310 and is locked and fixed to the connecting component 310 .

[0134] One end of the air duct inner component 330 is in contact with the connecting component 310 to seal the air duct.

[0135] The number of the air duct baffles 320 is matched with the number of the centrifugal air supply devices 510 .

[0137] In some embodiments, multiple centrifugal air supply devices 510 are provided, and multiple air duct partitions 320 are provided accordingly. The number of air duct partitions 320 is one more than the number of centrifugal air supply devices 510, so that two air duct partitions 320 are arranged on both sides of each centrifugal air supply device 510 to guide the airflow inside it. Multiple air duct partitions 320 cooperate with the inner tank top component 110, the connecting component 310 and the air duct internal component 330 to form multiple air duct structures, and the airflow of the multiple centrifugal air supply devices 510 is guided respectively.

[0138] In some embodiments of the present application, the air duct partition 320 includes a partition body, and a first folded portion 322 formed by folding from the partition body, a first threaded hole is provided on the first folded portion 322, and a first screw hole is provided on the inner liner top component 110.

[0142] By arranging the air duct baffle 320 and the centrifugal air supply device 510 at different intervals, a narrow airflow shielding portion 600 can be formed between the centrifugal air supply device 510 and the air duct baffle 320 which is closer thereto.

[0143] The formation of the narrow airflow shielding portion 600 blocks the airflow, preventing it from flowing circumferentially along the centrifugal air supply device 510, but causing it to flow along the remaining area outside the airflow shielding portion 600, thereby avoiding the generation of vortices and improving the air circulation efficiency.

[0145] Along the direction from the connecting member 310 to the water receiving component 530, the inclined portion 321 on the air duct blocking member 320 which is closer to the centrifugal air supply device 510 gradually approaches the centrifugal air supply device 510;

[0146] Along the direction from the connecting member 310 to the water receiving component 530 , the inclined portion 321 on the air duct blocking member 320 which is farther away from the centrifugal air supply device 510 gradually moves away from the centrifugal air supply device 510 .

[0147] The air duct barrier 320 further includes a first barrier portion 324 and a second barrier portion 325 .

[0148] The airflow shielding portion 600 is formed between the first barrier portion 324 and the inclined portion 321 and the centrifugal air supply device 500. Figure 5 shown.

[0149] When the centrifugal air supply device 510 rotates, the airflow will be continuously thrown out along its radial direction, and will be blocked when the airflow reaches the airflow shielding part, so that the airflow will no longer continue to flow in the circumferential direction, but will flow along the area outside the airflow shielding part 600, so that the air will not generate eddy currents around the centrifugal air supply device 510, thereby improving the air circulation efficiency.
