Refrigerated cabinets are used to create a low temperature environment for storing food and pharmaceuticals. For food, the low temperature environment not only can prolong the shelf life of the food, but also can make the specific food have certain flavor. For pharmaceutical products, suitable temperatures may prevent the product from accelerating failure due to excessive temperatures. For the refrigerator, the uniformity of the temperature in the refrigerator is very important, and local overheating or supercooling is not beneficial to the storage of food and medicine.

The refrigerating mode of the refrigerated cabinet is wind cooling type and direct cooling type. The direct cooling type freezer directly exchanges heat with the storage space through the refrigeration module, and the loss of moisture of a storage object can be reduced due to less air flowing, but the temperature close to the refrigeration module is obviously lower than other positions, and the temperature uniformity is poor. The air-cooled refrigerator takes away heat of a storage object through low-temperature air which circularly flows, has good temperature uniformity, and is suitable for storing packaged articles. The air outlet of the air-cooled refrigerator is positioned on the side wall, and the air return inlet is positioned at the top. In the air circulation process, the cold air descends, and the air flowability near the side wall opposite to the side wall where the air outlet is located is poor. For some articles that are critical to storage temperature, the temperature uniformity of the air-cooled cooler needs to be further improved.

With reference to fig. 1 to 6, an embodiment of the present disclosure provides a refrigerator, which includes a cabinet body, a vertical partition 150, an air outlet 151, and an air guide assembly 300, where an accommodating space is formed inside the cabinet body; the vertical partition plate 150 and a side plate of the cabinet body form a first interlayer, and the vertical partition plate 150 is provided with an air outlet 151; and the air guide assembly 300 is disposed at the air outlet 151 and extends from the vertical partition plate 150 to a direction away from the first interlayer.

In the disclosed embodiment, the refrigerator cabinet includes a top panel 110, a bottom panel 120, side panels 130, and a cabinet door 140, and the side panels 130 include a left side panel 131, a right side panel 132, and a back panel. The top plate 110, the bottom plate 120, the side plates and the cabinet door 140 enclose to define an accommodating space. The refrigerator further includes a partition dividing the accommodating space into a refrigerating space 410 and a storage space 420. The storage space 420 is used for storing articles, and the refrigerating space 410 is used for arranging a refrigerating device.

The partition plates include vertical partition plates 150 and horizontal partition plates 160, the vertical partition plates 150 form a first interlayer with the side plates, and the horizontal partition plates 160 form a second interlayer with the top plate 110. The first interlayer may be an interlayer formed by the vertical partition plate 150 and the back plate, an interlayer formed by the vertical partition plate 150 and the left side plate 131 or the right side plate 132, or an interlayer formed by the vertical partition plate 150 and the back plate, the left side plate 131 and the right side plate 132. The refrigerated space 410 includes a first compartment and a second compartment, the first compartment being in communication with the second compartment. In one embodiment, the end of the horizontal partition 160 near the back plate is joined to the top end of the vertical partition 150, and the section of the refrigerating space 410 parallel to the plane of the left side plate 131 or the right side plate 132 is an inverted L-shape. The vertical partition 150 is provided with an air outlet 151, and the horizontal partition 160 is provided with an air return opening 161. In the refrigerating space 410, the air flows from the air return opening 161 to the air outlet 151; in the storage space 420, the air flows from the air outlet 151 to the air return opening 161. With such an arrangement, the density of the hot air having exchanged heat with the storage object in the storage space 420 is small and increases upward, and the density of the cold air entering the storage space 420 from the air outlet 151 is large and decreases upward. This allows air to circulate sufficiently, and the temperature of each position in the storage space 420 to be reduced uniformly.

Only the air outlet 151 is formed in the vertical partition 150, and when the air in the refrigerating space 410 flows to the storage space 420 through the air outlet 151, the air flows through the small holes. The air flow type is molecular flow due to the low air pressure. In the molecular flow state, the air of the refrigerating space 410 is diffused toward the storage space 420 by a thermal motion. The air flow is not directional, and tends to gather near the outlet 151 and flow downward due to the difference in density between the hot and cold air. In this case, the cool air is mainly collected near the vertical partition 150 and does not flow well to a location far from the vertical partition 150, such as the cabinet door 140 location.

The refrigerator provided by the embodiment of the present disclosure further includes a wind guide assembly 300, and the wind guide assembly 300 extends from the vertical partition 150 to a direction away from the vertical partition 150. The air flowing through the air outlet 151 flows through the air guide assembly 300 and enters the storage space 420. The air guide assembly 300 has a certain length along the air flowing direction, and the air flowing model is the flowing of the air through the duct when the air flows through the air guide assembly 300. Because the flow velocity of the air is low, the inertia force of the air is also small, the mean free path of the air is far smaller than the pipe diameter, and the flowing type of the air is viscous-molecular flow. In this case, the internal friction in the air is significant, and the flow of the air is dominated by a laminar flow along the axial direction of the tube wall. Thus, the air guide assembly 300 allows the air to have an initial velocity in the direction of the duct and to be blown to a position far from the vertical partition 150. After leaving the air guide assembly 300, the air is quickly attenuated by the friction force of the air in the storage space 420 and moves downwards under the action of gravity. Compared with the arrangement that the air outlet 151 is formed in the vertical partition 150, the cold air entering the storage space 420 from the refrigerating space 410 can exchange heat with the air and the storage objects in the storage space 420 at a position relatively far away from the vertical partition 150, so that the cold air mainly exchanges heat at a position relatively central to the storage space 420, the temperature difference between the position near the vertical partition 150 and the position near the cabinet door 140 can be reduced, and the uniformity of the temperature in the refrigerating cabinet can be further improved.

Optionally, the air guiding assembly 300 includes an air guiding tube 310, a first end of which is linearly abutted to the air outlet 151, and a second end of which extends to the storage space 420.

The shape of the air duct 310 matches the shape of the air outlet 151, and the first end of the air duct 310 is a mounting end, fixed to the vertical partition 150, and covering the air outlet 151. The arrangement form has simple structure and lower cost.

Optionally, the conduction cross-sectional area of the second end of the air guiding assembly 300 is smaller than the conduction cross-sectional area of the air outlet 151.

With this arrangement, the air flowing from the refrigerating space 410 to the storage space 420 has a reduced cross-sectional area when passing through the air guide assembly 300, and the flow rate of the air is increased. This increases the distance between the air and the vertical partition 150, and reduces the temperature difference between the vicinity of the vertical partition 150 and a position away from the vertical partition 150 in the storage space 420.

Optionally, the second end of the air guiding pipe 310 is opened with a notch.

When the storage object is placed in the storage space 420, if the storage object approaches the air guiding pipe 310, the second end of the air guiding pipe 310 may be blocked, which may affect the air circulation effect. The second end of the air duct 310 is opened with a notch, and the end surface is a non-parallel surface. Even if the storage object is close to the second end of the air guide tube 310 or even abuts against the second end of the air guide tube 310, the air guide tube 310 can still maintain the conduction state. By adopting the arrangement form, the full and effective circulation of air in the refrigerated cabinet is facilitated, and the stability and uniformity of the temperature in the refrigerated cabinet can be improved.

Optionally, the second end of the air guiding tube 310 is provided with a gap above the air guiding tube 310.

Here, the upper side is the upper side of the refrigerator in the use state. The air passing through the air guide duct 310 has a relatively low temperature and sinks downward in the storage space 420 due to a difference in density between the hot and cold air. The gap is arranged above the air guide pipe 310, and has small influence on the movement distance of the air flowing through the air guide pipe 310 in the horizontal direction. By adopting the arrangement mode, the influence of opening the notch on the air supply distance can be reduced.

Optionally, the second end of the air guide duct 310 is configured with a protrusion in the air flow direction.

In order to avoid the air circulation effect being affected by the shielding of the second end of the air guiding pipe 310 when the storage object approaches the air guiding pipe 310, the second end of the air guiding pipe 310 is configured with a protrusion, and the end surface of the protrusion is a non-flush surface. Even if the storage object is close to the second end of the air guide tube 310 or even abuts against the second end of the air guide tube 310, the air guide tube 310 can still maintain the conduction state. By adopting the arrangement form, the full and effective circulation of air in the refrigerated cabinet is facilitated, and the stability and uniformity of the temperature in the refrigerated cabinet can be improved.

Optionally, the air outlet 151 is a flat hole arranged horizontally, and the air guiding pipe 310 is a flat pipe matched with the flat hole.

With this arrangement, the cross section of the air blown out through the second end of the air guide duct 310 in the plane perpendicular to the air guide duct 310 is elliptical. That is, the air blown out through the second end of the air guiding pipe 310 has a larger range of lateral diffusion than longitudinal diffusion. This facilitates uniform spreading of the cool air in the lateral direction. The cold air can move in the vertical direction under the action of the cold and hot density difference of the air. With such an arrangement, the uniformity of the temperature of the storage space 420 can be further improved.

Optionally, an included angle between the axis of the air guiding pipe 310 and the vertical partition plate 150 is greater than or equal to 45 ° and less than or equal to 135 °.

Within this angle range, the air blown out through the air guide duct 310 may move laterally for a long distance, which is advantageous to improve the uniformity of the temperature of the storage space 420.

Optionally, the number of the air outlets 151 is multiple, the air outlets 151 are spaced apart in the vertical direction, the number of the air guiding assemblies 300 is multiple, and the air guiding assemblies 300 are disposed on the air outlets 151 in a one-to-one correspondence.

The air outlets 151 are arranged, the air outlets 151 are spaced apart in the vertical direction, and cold air in the refrigerating space 410 can enter the storage space 420 from a plurality of positions of the vertical partition plate 150 through the air outlets 151 and the corresponding air guide assemblies 300. By adopting the arrangement form, the temperature uniformity of the refrigerated cabinet in the vertical direction can be improved.

Optionally, the lengths of the air guiding assemblies 300 extending from the vertical partition 150 from top to bottom are gradually reduced or gradually increased.

In the cooling space 410, the pressure drop of the air flowing from top to bottom is small, and the initial velocity of the air flowing through the plurality of air outlets 151 is relatively close. The distance between the air flowing through the air outlet 151 and the vertical partition 150 after entering the storage space 420 depends on the distance between the second end of the air guide assembly 300 and the vertical partition 150. The longer the air deflection assembly 300 extends from the vertical partition 150, the further the air can move laterally. The length of the plurality of air guide assemblies 300 extending from the vertical partition 150 is gradually reduced or increased, and the projections of the air blown out through the plurality of air guide assemblies 300 on the refrigerator base 120 are not completely overlapped. Thus, the cold air is uniformly distributed in the horizontal plane, and the uniformity of the temperature in the refrigerated cabinet is improved.

Optionally, the conduction sectional area of the second end of the wind guide assembly 300 is gradually increased or gradually decreased from top to bottom.

The larger the cross-sectional area of the second end of the air guide assembly 300, the smaller the initial velocity of the air, and the smaller the lateral movement distance of the air blown out through the air guide assembly 300. The conduction sectional area of the second ends of the air guide assemblies 300 is gradually increased or decreased, so that the cold air blown out by the air guide assemblies 300 can be more uniformly distributed in the horizontal direction, and the uniformity of the temperature in the refrigerator is improved.

Optionally, the refrigerated cabinet further includes a diaphragm plate 160, which forms a second interlayer with the top plate 110 of the cabinet body, the second interlayer is communicated with the first interlayer, and the diaphragm plate 160 is provided with an air return opening 161; the transverse partition plate 160 and the vertical partition plate 150 divide the space in the cabinet body into a storage space 420 and a refrigerating space 410, air in the refrigerating space 410 enters the storage space 420 through the air outlet 151, and air in the storage space 420 returns to the refrigerating space 410 through the air return opening 161.

The diaphragm plate 160 and the top plate 110 of the cabinet body form a second interlayer, the air return opening 161 is formed in the diaphragm plate 160, and hot air in the storage space 420 can return to the refrigerating space 410 through the air return opening 161 to complete cooling based on the distance of cold air descending during the hot air ascending. The arrangement mode can improve the circulation effect of the air in the refrigerated cabinet.

The refrigerating space 410 is used for cooling air, and the temperature of the air returning to the refrigerating space 410 from the air return opening 161 is lowered, and then the air enters the storage space 420 through the air outlet 151, and the above-mentioned operation is repeated, so that the temperature of the storage space 420 is lowered.

The refrigerated cabinet also includes a heat exchanger disposed in the refrigerated space 410, the temperature of the air flowing through the heat exchanger being reduced.

Optionally, the refrigerator further includes a fan 200 disposed in the second interlayer corresponding to the air return opening 161, wherein the fan 200 is used for driving the air in the storage space 420 to return to the refrigerating space 410 through the air return opening 161.

The fan 200 is disposed corresponding to the return air opening 161 for driving the air in the refrigerator cabinet to circulate between the refrigerating space 410 and the storage space 420. The first and second sandwiching layers have a large cross section, and the fan 200 is disposed corresponding to the air return opening 161, for example, covering the air return opening 161, so that the air flow driving function thereof can be realized with a small volume. The fan 200 has moving parts and the fan 200 is disposed in the second interlayer, which can improve the safety of the refrigerator in use. In addition, the fan 200 is arranged in the second interlayer, so that the storage space 420 in the refrigeration chamber has a neat appearance,

optionally, the number of the air return openings 161 is multiple, the air return openings 161 are arranged at intervals, the number of the fans 200 is multiple, and the fans 200 correspond to the air return openings 161 one by one.

The arrangement of the plurality of air return openings 161 and the plurality of fans 200 can make full use of the space of the second interlayer and the area of the diaphragm 160, thereby improving the air circulation effect of the refrigerator.

Optionally, the refrigerator further includes a return air inlet cover 162 covering the return air inlet 161, and the return air inlet cover 162 has a plurality of hollows.

The air return opening 161 is arranged on the cover plate, so that the use safety of the refrigerated cabinet can be further improved. The air return opening cover plate 162 is hollowed out at a plurality of positions so that the air in the storage space 420 can smoothly return to the refrigerating space 410 through the air return opening 161.

Optionally, the air return cover plate 162 is hollowed out to form spokes.

The rotation of the fan blades of the fan 200 drives the air flow, which swirls around the fan 200. The air return cover plate 162 is spoke-shaped, so as to have a certain flow rectification effect, and air passing through the air return cover plate 162 can flow orderly, so that the air is better driven by the fan 200 to circulate between the storage space 420 and the refrigerating space 410.

Optionally, the refrigerated case is also configured with an appliance mounting space 430.

The electric appliance mounting space 430 is used for mounting the electric control box and a heat generating part of the refrigerating apparatus. This prevents the heat generated during operation of the refrigerator from affecting the temperature of the refrigerated space 410 or the storage space 420.

Optionally, the appliance mounting space 430 is located below the bottom plate 120 of the case.

By adopting the arrangement mode, on one hand, the gravity center of the refrigerated cabinet is lower and more stable, and on the other hand, the vibration of the vibration part in the electric appliance installation space 430 is not easy to cause the resonance of the refrigerated cabinet body, so that the running noise of the refrigerated cabinet can be reduced.

Optionally, the refrigerator includes a refrigerant circulation system formed by connecting a compressor, a condenser, a throttling device and an evaporator in sequence through pipes, wherein the compressor, the condenser and the throttling device are located in the electric appliance installation space 430, and the evaporator is located in the first interlayer and/or the second interlayer.

The refrigerant circulating system has high refrigerating efficiency, and the refrigerating capacity of the refrigerated cabinet can be improved by using the refrigerant circulating system as refrigerating equipment of the refrigerated cabinet.
