Description

Technical Field

[0001] The utility model relates to the technical field of refrigeration equipment, in particular to an improvement on the structure of refrigeration equipment. Background Art

[0002] Existing refrigeration equipment, such as kitchen refrigerators, generally adopts an axial flow fan structure, and the axial flow fan is also assembled and arranged at the top of the refrigerator 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.

[0069] The utility model provides an embodiment of a refrigeration device, comprising:

[0070] The box body 100 includes an inner liner component 110, a storage chamber 120 is defined in the inner liner component 110, and the inner liner component 110 includes an inner liner top wall 111.

[0071] 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 .

[0072] The inner liner component 110 is arranged inside the box shell. The inner liner component 110 is connected and fixed to the box shell and a foaming cavity is formed between the inner liner component 110 and the box shell. The foaming cavity is filled with foaming material.

[0073] The inner container component 110 includes an inner container top plate, forming an inner container top wall 111;

[0074] The inner tank side panel is used to form the inner tank side wall;

[0075] The inner liner back wall constituting the inner liner back plate, the inner liner top plate, the inner liner side plates and the inner liner back plate constitute the inner liner component 110, which can be directly integrally formed through the vacuum forming process during molding.

[0076] In some embodiments of the present application, the refrigeration device further includes a door body 140 , which is rotatably connected to the cabinet 100 to open or close the storage chamber 120 .

[0077] A storage chamber 120 for storing food is defined inside the inner container part 110 , and the storage chamber 120 is a freezing chamber or a refrigerating chamber.

[0078] In some embodiments of the present application, the door body 140 includes an upper door body and a lower door body.

[0079] The upper door body includes two upper door bodies that are arranged to open opposite to each other. The two upper door bodies can open or close the upper area of ​​the storage chamber 120 by opening or closing the two upper door bodies relative to each other.

[0080] The lower door body includes two lower door bodies that are arranged to open opposite to each other. The two lower door bodies can open or close the lower area of ​​the storage chamber 120 by opening or closing the two lower door bodies relative to each other.

[0081] The air duct assembly is located in the storage chamber 120 and is assembled on the inner liner top wall 111. An air duct is formed between the air duct assembly and the inner liner top wall 111. The air duct has an air inlet 3221 communicating with the storage chamber 120.

[0082] The air duct structure is formed by the cooperation and connection between the air duct assembly and the inner tank top wall 111. The air inlet portion 3221 is an air inlet, which can be used to connect the storage chamber 120 and the air duct so that the airflow in the storage chamber 120 can enter the interior of the air duct.

[0083] In some embodiments of the present application, the air duct assembly includes:

[0084] The air duct cover 200 is buckled on the inner liner top wall 111, and a folding portion is formed on its circumference, and a plurality of locking portions for connecting with the inner liner top wall 111 are formed on the folding portion.

[0085] The folding portion is a folding edge, and the locking portion is a locking hole arranged on the folding edge.

[0086] When connected, the air duct cover 200 is turned over to fit the inner liner top wall 111 and is locked and fixed to the inner liner top wall 111 by passing the locking screw through the locking hole.

[0087] The centrifugal air supply device 400 can be shielded by buckling the air duct cover 200 onto the top wall 111 of the inner container.

[0088] The bottom surface of the air duct cover 200 faces the storage chamber 120 and is arranged horizontally, that is, arranged parallel to the horizontal plane.

[0089] The air duct baffle 300 is vertically arranged between the inner liner top wall 111 and the air duct cover 200, with one end being fitted and fixed to the inner liner top wall 111, and the other end being fitted and fixed to the air duct cover to form an air duct together with the inner liner top wall 111 and the air duct cover 200.

[0090] An air duct for placing a centrifugal air supply device 400 is formed by connecting the air duct baffle 300 to the inner tank top wall 111 and the air duct cover 200. The setting of the air duct can ensure that the airflow entering the interior flows along the set flow path without air turbulence.

[0091] The air duct has an air duct outlet, and the air duct outlet is arranged toward the evaporator 500, so as to ensure that the air flow flowing through the air duct is directly blown toward the evaporator 500 when flowing out from the air duct outlet.

[0092] The centrifugal air supply device 400 is located in the air duct, mounted on the top wall 111 of the inner tank, and arranged horizontally, with its axis extending in the vertical direction;

[0093] The centrifugal air supply device 400 is a centrifugal fan, which is horizontally mounted on the top wall 111 of the inner container. The centrifugal fan is arranged horizontally, that is, the axis of the centrifugal fan is arranged to extend along the vertical direction. The horizontal arrangement of the centrifugal fan can effectively reduce the vertical space occupied by the centrifugal fan as a whole, thereby greatly reducing the occupation of the storage chamber 120 for storing food.

[0094] In some embodiments, the inner tank top wall 111 is arranged horizontally, the axis of the centrifugal fan is arranged perpendicular to the inner tank top wall 111 , and the centrifugal fan is arranged parallel to the inner tank top wall 111 .

[0095] Correspondingly, since the centrifugal air supply device 400 is arranged horizontally as a whole, the air duct cover 200 used to shield it is also arranged horizontally, and its bottom surface is parallel to the horizontal plane, thereby thinning the thickness of the entire air duct and reducing the occupied space.

[0096] In some embodiments of the present application, a fan mounting frame 900 is further included. The fan mounting frame 900 is a fan mounting plate, whose shape profile is adapted to the profile of the centrifugal fan, and a plurality of screw locking holes are formed around the fan.

[0097] During installation, the centrifugal air supply device 400 is fixed against the fan mounting plate, and then the fan mounting plate is fixedly connected to the top wall 111 of the inner tank to realize the assembly of the centrifugal air supply device 400.

[0098] The fan mounting frame 900 is configured as a fan mounting plate structure to support and fix the fan. The fan mounting plate has a small thickness, which can reduce the vertical space occupied in the vertical direction and increase the internal space of the storage chamber 120.

[0099] The evaporator 500 is mounted on the top wall 111 of the inner tank and arranged on one side of the centrifugal air supply device 400 and arranged horizontally;

[0100] In some embodiments, the evaporator 500 is formed by bending an evaporating aluminum tube.

[0101] The evaporator 500 is arranged horizontally, which can reduce its occupation of the storage chamber 120 and increase the space for storage compared with its vertical arrangement.

[0102] During assembly and fixing, the evaporator 500 can be fixed on the top wall 111 of the inner container by screwing. After assembly and fixing, the evaporator 500 is arranged parallel to the inner container and in close contact with the top wall 111 of the inner container.

[0103] Since the centrifugal air supply device 400 takes in air along the axial direction and discharges air along the radial direction, when the centrifugal air supply device 400 is arranged horizontally, it can take in air along the vertical direction and then discharge air along the horizontal direction.

[0104] The evaporator 500 is arranged at the air outlet side of the centrifugal air supply device 400 and arranged side by side with the centrifugal air supply device 400, mainly to ensure that the airflow blown out from the centrifugal air supply device 400 can be directly blown out of the evaporator 500, so as to ensure that the airflow sucked from the storage chamber 120 by the centrifugal air supply device 400 can flow through the evaporator 500 for heat exchange.

[0105] The water receiving component 600 is used to receive the condensed water on the evaporator 500;

[0106] Since the evaporator 500 is placed on top, in order to receive the condensed water on the evaporator 500 , the water receiving component 600 is also placed on top to collect the condensed water and prevent the condensed water from dripping from the top into the storage chamber 120 .

[0107] The water receiving component 600 is buckled on the top wall 111 of the inner container and is surrounded by the top wall 111 of the inner container to form an evaporation chamber cavity;

[0108] In order to achieve the top fixation of the water receiving component 600, the water receiving component 600 is buckled on the inner tank top wall 111 and screwed to lock and fix it to the inner tank top wall 111. The evaporation chamber formed by the water receiving component 600 and the inner tank top wall 111 can be used to accommodate the evaporator 500, so that the user can see the top evaporator 500 structure after opening the door, and it is shielded by the water receiving component 600.

[0109] The evaporation chamber cavity is communicated with the air duct to ensure that the airflow sucked into the air duct by the centrifugal air supply device 400 can be delivered to the evaporator 500 located in the evaporation chamber cavity.

[0110] The water receiving component 600 is provided with an air outlet 610 communicating with the storage chamber 120 . The air outlet 610 is an air outlet formed on the water receiving component 600 , and the air outlet is communicated with both the evaporation chamber cavity and the storage chamber 120 .

[0111] After the airflow exchanges heat through the evaporator 500, it is blown outward along the air outlet 610. Since the air outlet 610 is connected to the storage chamber 120, the airflow can enter the storage chamber 120, so that the airflow that exchanges heat through the evaporator 500 enters the storage chamber 120 for cooling and refrigerating or freezing food.

[0112] When the centrifugal air supply device 400 is in operation, it can drive the air flow to circulate between the storage chamber 120, the air duct and the evaporation chamber.

[0113] In some embodiments of the present application, the refrigeration device further includes a compressor 800, a condenser, and a solenoid valve, which are connected to the evaporator 500 through a refrigerant pipeline to form a refrigeration cycle system.

[0114] The refrigeration system includes a compressor 800 configured to compress a refrigerant;

[0115] a condenser configured to condense the refrigerant;

[0116] an evaporator 500 configured to evaporate the refrigerant condensed by the condenser, and the refrigerant evaporated by the evaporator 500 is configured to cool the storage chamber 120;

[0117] The refrigerant circulation loop allows the condensate to circulate in a loop consisting of the compressor 800, the evaporator 500, the condenser, the solenoid valve and the throttling device;

[0118] The refrigeration system performs a refrigeration cycle of the refrigeration device by using the compressor 800, the condenser, the solenoid valve, the evaporator 500, and the throttling device.

[0119] The low-temperature and low-pressure refrigerant enters the compressor 800, which compresses it into a high-temperature and high-pressure refrigerant gas and discharges the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser. The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the surrounding environment through the condensation process.

[0120] The evaporator 500 may cool the items in the cabinet 100 by using latent heat of evaporation of the refrigerant.

[0121] In some embodiments of the present application, the box body 100 is divided into a storage chamber 120 and an installation space 130 , and the installation space 130 is arranged above the storage chamber 120 .

[0122] The compressor 800 , the condenser, and the refrigerant pipeline are arranged in the installation space 130 .

[0123] The refrigerant pipeline connected to the evaporator 500 may extend from the storage chamber to the installation space 130 to connect the evaporator 500 and the compressor 800 .

[0124] In the refrigeration equipment of this embodiment, the air supply device is replaced by a centrifugal air supply device 400 instead of an axial air supply device.

[0125] The centrifugal air supply device 400 is used as an evaporation fan, and the input power is less than 5W, making the cabinet more energy-efficient;

[0126] The centrifugal air supply device 400 is used as an evaporation fan, the air volume meets the use requirements, the fan speed is high, and the noise is low.

[0127] The centrifugal air supply device 400 is used as an evaporation fan and is 12V weak current, making the cabinet safer.

[0128] The centrifugal air supply device 400 is arranged horizontally, and the evaporator 500 is arranged horizontally on one side thereof, which reduces the height of the air supply device and the evaporator 500 as a whole, reduces the occupation of the internal space of the storage chamber 120, and increases the storage space of the storage chamber 120;

[0129] The centrifugal air supply device 400 is arranged horizontally so that the air duct cover 200 mounted on the inner tank component 110 for accommodating the centrifugal air supply device 400 does not need to be arranged tilted but is arranged horizontally to match it, with the bottom surface parallel to the horizontal plane;

[0130] The evaporator 500 is arranged horizontally so that the water receiving component 600 of the cover buckle evaporator 500 can also match the horizontal evaporator 500 to maintain a substantially horizontal arrangement. When viewed from the outside, the air duct assembly is arranged horizontally, and the water receiving component 600 is basically arranged horizontally. Compared with the inclined arrangement, it not only reduces the occupation of the storage chamber 120 space, but also reduces the pressure feeling of the user when opening the door, thereby improving the user comfort.

[0131] In terms of overall structure, the centrifugal air supply device 400 is horizontally assembled on the top wall 111 of the inner tank, the evaporator 500 is arranged side by side with it, the air duct assembly cover is buckled on the top wall 111 of the inner tank, and the water receiving component 600 is buckled on the evaporator 500. The overall structure is compactly arranged and occupies little space.

[0132] When the refrigeration equipment is running, the centrifugal air supply device 400 is activated, and the air flow in the storage chamber 120 is sucked into the inside of the air duct through the air inlet 3221, and then blown out to the evaporator 500 in the evaporation chamber connected to the air duct for heat exchange. After the heat exchange, it is blown out from the air outlet 610 and enters the storage chamber 120 to perform a refrigeration cycle.

[0133] In some embodiments of the present application, the air duct cover 200 includes:

[0134] A cover body 210, wherein a through portion 211 is provided on the cover body 210;

[0135] The cover mesh cover 220 corresponds to the position of the centrifugal air supply device 400 , which blocks the position of the penetration portion 211 and is locked and fixed to the cover body 210 .
