DETAILED DESCRIPTION

[0037] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0038] The terms "including" and "having" and any variations thereof in the present invention are intended to cover non-exclusive inclusions. Reference to "embodiments" herein means that the specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0039] Combination Figures 1 to 3 As shown, the present invention mainly relates to: a refrigerator, comprising a box body 1 and a refrigeration component arranged in the box body 1. The box body 1 defines a storage compartment 13 and an evaporator compartment 14 for placing the refrigeration component. The storage compartment 13 is used for storing. The evaporator compartment 14 is arranged adjacent to the lower side of the storage compartment 13.

[0040] The refrigeration component includes an evaporator 15 and a fan 16 , and is used to provide cooling for the storage compartment 13 .

[0041] The refrigerator includes a door body for opening or closing the storage compartment 13 , and the door body is arranged at the opening of the storage compartment 13 .

[0042] Combination Figure 1As shown, in this embodiment, the refrigerator includes a return air hood 2 arranged at the opening of the storage compartment 13 and extending toward the evaporator compartment 14. The return air hood 2 extends backward from the opening of the inner tank. Condensation is easily formed at the opening in the storage compartment 13 due to the large temperature difference between the inside and the outside.

[0043] Combination Figure 5 As shown, the return air cover 2 includes a plurality of transverse ribs 21 spaced apart in the vertical direction, and a first return air port 212 connecting the storage compartment 13 and the evaporator compartment 14 is defined between two adjacent transverse ribs 21. There are a plurality of first return air ports 212. The plurality of first return air ports 212 are spaced apart in the vertical direction. The return air flow in the storage compartment 13 is sucked into the evaporator compartment 14 by the fan 16 through the first return air port 212.

[0044] The transverse rib 21 has an inclined portion 211, and the inclined portion 211 is inclined in a direction from the opening side of the box body 1 to the direction away from the opening side of the box body 1. The opening side of the box body 1 is defined as the front side.

[0045] The inclined transverse ribs 21 can cover the internal structure of the evaporator compartment 14, and have the advantages of a simple and high-end appearance.

[0046] When the fan 16 is working, the fan 16 draws the air of the storage compartment 13 into the evaporator compartment 14 through the first return air port 212. At the same time, condensation formed at the opening in the storage compartment 13 will remain on the transverse rib 21. When condensation appears on the transverse rib 21, it is blown away by the fan 16. The present invention increases the contact area of ​​condensation by making the transverse rib 21 inclined, so that the condensation can be dried more thoroughly. When the condensation is large and forms water droplets, the water droplets are blown away by falling downward.

[0047] Combination Figure 3 As shown, further, the box body 1 includes an inner liner 11, and a storage compartment 13 and an evaporator compartment 14 are located in the inner liner 11 and are separated by a cover plate 3 covering the evaporator compartment 14. The cover plate 3 separates the internal space of the inner liner 11 into the storage compartment 13 and the evaporator compartment 14 which are arranged adjacent to each other up and down. The evaporator compartment 14 is defined between the cover plate 3 and the bottom wall of the inner liner 11.

[0048] The return air cover 2 is arranged on the front side of the cover plate 3 and extends downward from the top of the cover plate 3 to the bottom wall of the inner tank 11. The return air cover 2 first extends forward from the top of the cover plate 3 and then extends downward to the bottom wall of the inner tank 11.

[0049] Furthermore, the inclined portion 211 is arranged to be inclined upward in the direction from front to back. The front end of the inclined portion 211 is lower than the rear end of the inclined portion 211, which is convenient for condensation to drip downward and also convenient for the mold forming of the return air cover 2.

[0050] Furthermore, the return air cover 2 further includes a horizontal portion extending backward from the inclined portion 211 , and the horizontal portion is arranged closer to the cover plate 3 than the inclined portion 211 .

[0051] Combination Figure 5 As shown, further, the return air cover 2 includes a guide rib 22 arranged below the transverse rib 21, and the guide rib 22 is arranged below the lowest transverse rib 21 at intervals.

[0052] The front end surface of the guide rib 22 protrudes further toward the opening side of the box body 1 than the front end surface of the transverse rib 21. The front end surface of the guide rib 22 is arranged closer to the opening side of the box body 1, and when the condensation is large and forms water droplets, it drips down onto the guide rib 22, so that the guide rib 22 plays the function of receiving water.

[0053] The top of the guide rib 22 is tilted downward from the front to the back. When water drops fall on the guide rib 22, the water drops flow to the rear of the guide rib 22 due to the guide top surface of the guide rib 22 tilting backward and downward, so that the guide rib 22 plays a water guiding function. At the same time, the fan 16 of the evaporator compartment 14 will also blow away the water drops flowing to the rear of the guide rib 22, avoiding water drops in front of the guide rib 22, thereby improving the cleanliness of the bottom of the storage compartment 13, and improving the aesthetics and neatness.

[0054] Furthermore, the return air cover 2 also includes a vertical rib 23 whose front end of the guide rib 22 extends downward and connects to the bottom of the inner tank 11 .

[0055] Combination Figure 4 As shown, the vertical ribs 23 are spaced apart from the cover plate 3 and define a water accumulation area 27. The guide ribs 22, the vertical ribs 23, the bottom of the liner 11 and the cover plate 3 together form the water accumulation area 27. In this embodiment, the return air cover 2 is integrally formed.

[0056] Furthermore, the bottom wall of the inner tank 11 is recessed downward to form a water collecting groove 12 having a drain port 121. The water collecting groove 12 is disposed below the evaporator 15. The bottom wall of the inner tank 11 is inclined downward toward the water collecting groove 12 at the front and rear sides and the left and right sides of the water collecting groove 12, so that the water directed to the bottom wall of the inner tank 11 flows down to the water collecting groove 12. In other words, the drain port 121 of the water collecting groove 12 is the lowest area of ​​the bottom wall of the inner tank 11.

[0057] Combination Figure 5 As shown, a water guide port 241 is vertically provided on the top of the return air cover 2, and the top of the return air cover 2 is inclined toward the water guide port 241 on both sides of the water guide port 241. In this embodiment, the top of the return air cover 2 is inclined toward the water guide port 241 on both sides of the water guide port 241.

[0058] It is understandable that a storage drawer or other storage device is provided in the storage compartment 13. Water droplets from the front cover of the storage drawer or other storage device condensate drops to the top of the return air cover 2, and flows down to the water guide port 241 through the inclined surfaces formed on both sides of the water guide port 241.

[0059] The cover plate 3 forms a water guide portion corresponding to the lower portion of the water guide port 241, which connects the water guide port 241 and the water collecting groove 12. Water dripping from the front cover of the storage drawer or other storage device flows from the water guide port 241 into the water collecting groove 12 through the water guide portion, and is discharged into the evaporating dish for placing defrost water outside the inner pot 11 through the drain port 121. In this embodiment, the water guide portion is formed on the cover plate 3, and it is understandable that the water guide portion can also be fixed to the cover plate 3 by other connection methods.

[0060] Preferably, the cabinet 1 further comprises a press chamber disposed below the evaporator compartment 14. An evaporating dish is disposed in the press chamber, and a water containing cavity is formed in the evaporating dish. The refrigerator further comprises a defrosting drain pipe connecting the drain port 121 and the containing cavity.

[0061] Combination Figure 6 As shown, the cover plate 3 further includes a horizontal inclined portion 31 that is inclined downward from the back to the front, and a vertical inclined portion 32 that extends downward from the horizontal inclined portion 31 to the bottom of the inner container 11. Water drops that drip onto the cover plate 3 will also flow forward along the inclined direction of the horizontal inclined portion 31, and be guided to the outside of the inner container 11 through the water guide portion.

[0062] The vertical inclined portion 32 includes a plurality of second return air ports 322 spaced apart in the left-right direction. Specifically, the vertical inclined portion 32 includes a plurality of vertical ribs 321 spaced apart in the left-right direction, and two adjacent vertical ribs 321 define a second return air port 322 .

[0063] The water guide portion includes an inclined connection portion 37 formed at the connection between the horizontal inclined portion 31 and the vertical inclined portion 32 . The inclined connection portion 37 is disposed directly below the water guide port 241 .

[0064] Since the vertical inclined portion 32 is formed by the downward extension of the horizontal inclined portion 31, the inclined connecting portion 37 is also formed by the downward extension, and the inclined connecting portion 37 is arranged to be inclined downward in the back-to-front direction. The water in the water guide port 241 will flow downward through the inclined connecting portion 37, and then flow to the bottom wall of the inner tank 11 in the storage compartment 13 through the second return air port 322 arranged on the vertical inclined portion 32, and at the same time be discharged to the evaporating dish outside the inner tank 11 for placing defrosting water through the drain port 121. It has the advantages of compact structure and reasonable layout. The moisture in the return air flow can also be condensed in advance at the transverse ribs 21 and the vertical inclined portion 32, and at the same time, water is formed under the wind force of the fan 16, and is diverted to the water collecting groove 12 through the water guide portion, thereby reducing the moisture condensed on the evaporator 15, thereby reducing the frosting of the evaporator 15.

[0065] Furthermore, the water guide portion also includes a bent water guide portion 33 formed by the lateral middle portion of the front wall of the vertical inclined portion 32 extending obliquely downward to both lateral sides, and an inclined water guide portion 34 extending forward from the bottom of the vertical inclined portion 32. Among them, the inclined water guide portion 34 is arranged to be inclined downward from front to back. The bottom of the second return air port 322 is connected to the inclined water guide portion 34. In other words, the water flowing into the inclined water guide portion 34 is guided into the water collecting groove 12 through the second return air port 322. The bent water guide portion 33 is arranged below the inclined water guide portion 34.

[0066] When the water passing through the water guide port 241 flows downward through the inclined connection portion 37, it will naturally flow to the bent water guide portion 33, so that the water flows downward along the bent water guide portion 33 to the inclined water guide portion 34, and then flows downward along the inclination of the inclined water guide portion 34, and then flows downstream through the lower part of the second return air port 322 to the bottom wall of the inner tank 11 located in the evaporator compartment 14. The arrangement of the bent water guide portion 33 and the inclined water guide portion 34 prevents water droplets from directly flowing into the evaporator compartment 14 through the upper part of the inclined water guide portion 34 and the second return air port 322, and prevents water droplets from splashing onto the evaporator 15, thereby reducing the amount of frost on the evaporator 15.

[0067] Preferably, a water guiding space is defined between the bent water guiding portion 33 and the side wall of the inner container 11, so that water flows downward along the water guiding space.

[0068] In this embodiment, the bottom wall of the inner tank 11 protrudes upward to form a convex rib. The convex rib is arranged at the bottom of the cover plate 3. The convex rib is arranged to separate the storage compartment 13 and the evaporator compartment 14 in the front-to-back direction. The convex rib includes a horizontal inclined surface arranged at the highest point. The inclined water guide portion 34 is arranged at the top of the horizontal inclined surface to prevent the water of the guide portion from flowing into the storage compartment 13.

[0069] Combination Figure 4As shown, specifically, the convex rib includes a horizontal surface 122, a vertical surface 123 extending upward from the horizontal surface 122, a horizontal inclined surface 124 extending backward from the vertical surface 123 and arranged at the bottom of the inclined water guide portion 34, and a vertical inclined surface 125 extending downward from the horizontal inclined surface 124. Among them, the vertical rib 23 is vertically arranged on the upper part of the horizontal surface 122. The vertical inclined surface 125 is used to form the evaporator compartment 14 with the cover plate 3. The setting of the convex rib separates the storage compartment 13 and the evaporator compartment 14 in the front-to-back direction, preventing the water in the guide portion from flowing into the storage compartment 13, thereby improving the neatness and aesthetics of the storage compartment 13.

[0070] Combination Figure 5 As shown, further, the return air cover 2 includes a first cover plate 24 disposed on the top of the horizontal inclined portion 31. A water guide port 241 is formed on the first cover plate 24.

[0071] A water guide channel is defined between the first cover plate 24 and the top of the horizontal inclined portion 31, and the entrance of the water guide channel is formed at the rear end of the first cover plate 24. The water guide channel is connected to the water guide portion. The left and right side edges of the first cover plate 24 extend downward to form a water guide channel with the top of the horizontal inclined portion 31, which has the advantages of simple structure and easy implementation.

[0072] The horizontal inclined portion 31 is inclined downward from the back to the front, and water drops falling on the cover plate 3 will also flow forward along the inclined direction of the water guide channel and be guided to the outside of the inner tank 11 through the water guide. The detailed description of how the water guide guide guides has been described above and will not be repeated here.

[0073] Furthermore, the return air cover 2 further includes a second cover plate 26 extending downward from the front end of the first cover plate 24 , and the second cover plate 26 is disposed at the front side of the vertical inclined portion 32 . The transverse ribs 21 are formed on the second cover plate 26 .

[0074] Preferably, a return air space is defined between the second cover plate 26 and the vertical inclined portion 32 for supplying air to the first return air outlet 212 and flowing to the second return air outlet 322. The provision of the return air space also provides a preset space for the provision of the inclined water guide portion 34.

[0075] Furthermore, the first cover plate 24 is downwardly extended to form a plurality of spaced-apart diverter ribs 25 , and the diverter ribs 25 are extended in the front-to-back direction.

[0076] Among them, a plurality of diversion ribs 25 separate the water guide channel into a plurality of diversion channels.

[0077] Furthermore, the second cover plate 26 includes a second cover plate body and a clamping block 261 extending rearwardly from the second cover plate body.

[0078] The cover plate 3 includes a vertical extension portion 35 extending downward from the inclined water guide portion 34 and a clamping portion 36 extending forward from the vertical extension portion 35. The clamping portion 36 is provided with a clamping hole for the clamping block 261 to be clamped in. The clamping block 261 cooperates with the clamping portion 36 to form a whole with the cover plate 3.

[0079] The vertical extension portion 35 is also vertically disposed on the top of the horizontal plane 122 .

[0080] Furthermore, the evaporator 15 is disposed at the bottom of the horizontally inclined portion 31, and the fan 16 is disposed behind the evaporator 15 and vertically fixed to the rear wall of the inner tank 11. A first end 151 of the evaporator 15 close to the fan 16 is higher than a second end 152 of the evaporator 15 away from the fan 16.

[0081] Furthermore, the evaporator 15 includes a plurality of fins spaced apart in the left-right direction, and the air flows in a direction parallel to the fins.

[0082] Combination Figure 3 As shown, an upper insulation layer 17 is provided on the upper side of the evaporator 15, and the upper insulation layer 17 is provided between the horizontal inclined portion 31 and the evaporator 15. The inclination of the upper insulation layer 17 is adapted to the horizontal inclined portion 31. The surface of the upper insulation layer 17 facing the evaporator 15 is an inclined structure, and the inclined structure gradually extends obliquely upward from the second end 152 away from the fan 16 toward the first end 151 close to the fan 16, so that the second end 152 is lower than the first end 151. It is prevented that the defrosting water generated by the defrosting of the evaporator 15 affects the normal operation of the fan 16, and it is convenient for the defrosting water generated by the evaporator 15 to flow into the water collecting groove 12.

[0083] Preferably, the bottom of the fan 16 is higher than the bottom of the second end 152 of the evaporator 15 .

[0084] Furthermore, the refrigerator further comprises an air duct plate assembly 4 arranged at the rear wall of the inner tank 11. The air duct plate assembly 4 defines an air outlet 41 connecting the evaporator compartment 14 and the storage compartment 13, and a plurality of air outlets 42 connecting the air outlet 41 and the storage compartment 13 respectively. The plurality of air outlets 42 are arranged at intervals in the vertical direction. The air outlets 42 are arranged forward. In other words, a refrigeration air path with air outlet at the rear side and air return at the bottom is formed. The refrigeration air path has the advantages of reasonable design and high space utilization.

[0085] The fan 16 is a centrifugal fan, the front of which is provided with an air inlet 161, and the top of which is provided with an air outlet 162. The air outlet 41 is connected to the air outlet 162 of the centrifugal fan to improve the driving ability of the fan 16.

[0086] Preferably, the air suction port 161 is arranged directly opposite to the first air return port 212 to improve the air suction capacity of the fan 16 .

[0087] Furthermore, the cover plate 3 includes a horizontal inclined portion 31 extending backwards to an inclined extension portion at the air duct plate assembly 4. The arrangement of the inclined extension portion allows a preset spacing between the evaporator 15 and the fan 16 to prevent the defrosting water generated by the defrosting of the evaporator 15 from affecting the normal operation of the fan 16, thereby increasing the service life of the fan 16.

[0088] Compared with the prior art, the refrigerator provided by the present invention arranges the evaporator compartment 14 adjacent to the lower side of the storage compartment 13, the return air hood 2 includes a plurality of transverse ribs 21 spaced apart from each other, the transverse ribs 21 between two adjacent transverse ribs 21 define a first return air port 212, the fan 16 draws the air of the storage compartment 13 into the evaporator compartment 14 through the first return air port 212, and at the same time, the condensation formed at the opening in the storage compartment 13 remains at the transverse rib 21, the fan 16 takes away the condensation at the transverse rib 21 by wind, the transverse rib 21 has an inclination, which increases the contact area of ​​the condensation, so that the condensation is blown dry more thoroughly, and when the condensation is large and forms water droplets, the water droplets are blown away by falling downward, which has the advantages of reducing condensation, lowering humidity, and having a neat appearance.
