[0002] At present, the refrigerator air duct refers to the channel structure used to transport airflow inside the refrigerator. The refrigerator air duct is connected to various spaces such as the evaporator, the cold storage compartment, and the freezer compartment. When the refrigerator is working, the cold energy generated by the compressor absorbs heat through the evaporator and becomes cold air, and then the cold air is evenly transported to the refrigerator's cold storage compartment and freezer compartment through the air duct to achieve refrigeration or freezing of food. A damper is set inside the air duct to control the flow direction and flow rate of the air flow. During the operation of the refrigerator, water droplets are easily generated in the air duct, and the water flows along the inner wall of the air duct to the damper. The water will condense into frost when it encounters cold, which can easily freeze the damper.

The heater can heat the damper, and even if the air cooled by the refrigerator blows on the damper, the damper can be heated by the heater to prevent the damper from frosting or icing, and ensure that the damper can be opened and closed normally.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related art:

[0005] Adding a heater to heat the damper to ensure normal opening and closing of the damper will increase costs, and the overall energy consumption of the refrigerator will increase when the heater is working.

[0039] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0040] Combination Figure 1-2As shown, the embodiment of the present disclosure provides an air duct assembly, including: an air duct body 100 and an air door 200. The air duct body 100 defines an air flow vent cavity 300, and a water storage tank 400 is provided on the inner side wall of the air flow vent cavity 300, and the water storage tank 400 is perpendicular to the air flow direction in the air flow vent cavity 300; the air door 200 is arranged in the air flow vent cavity 300, and in the vertical direction, the water storage tank 400 is located above the air door 200.

[0041] With the air duct assembly provided by the embodiment of the present disclosure, since a water storage tank 400 is provided on the inner side wall of the flow ventilation cavity 300, when there is water on the inner side wall of the flow ventilation cavity 300, the water flows into the water storage tank 400 along the inner side wall of the flow ventilation cavity 300, and the water storage tank 400 intercepts water droplets and temporarily stores the water, thereby reducing the risk of water flowing to the damper 200 and freezing at the damper 200, and ensuring that the damper 200 can be opened and closed normally. The cost of opening the water storage tank 400 is low, and the power consumption of operation will not be increased. In addition, the airflow circulating in the flow ventilation cavity 300 will dry the water in the water storage tank 400, so that the water storage tank 400 can intercept water droplets and temporarily store water again.

[0042] Optionally, the two ends of the water storage tank 400 are interconnected. In this way, when there is water on the inner wall of the flow ventilation cavity 300, the water flows into the water storage tank 400 along the inner wall of the flow ventilation cavity 300, and the two ends of the water storage tank 400 are interconnected to form an annular groove on the inner wall of the flow ventilation cavity 300, so that the range of intercepting water droplets is larger and the interception effect is better.

[0043] Combination Figure 3 As shown, optionally, an extension groove 410 connected to the water storage tank 400 is provided at the lower side of the water storage tank 400. In this way, by providing the extension groove 410 at the lower side of the water storage tank 400, the water in the water storage tank 400 can flow into the extension groove 410, and the water is temporarily stored in the extension groove 410 to increase the water storage capacity.

[0044] Specifically, the extension groove 410 extends downward in the vertical direction from the lower side wall of the water storage tank 400. In this way, by providing the extension groove 410 at the lower side of the water storage tank 400, water in the water storage tank 400 can flow into the extension groove 410, and the water is temporarily stored in the extension groove 410, thereby increasing the water storage capacity.

[0045] Optionally, a plurality of extension grooves 410 are provided. Thus, by providing a plurality of extension grooves 410 at the lower side of the water storage tank 400, water in the water storage tank 400 can flow into the extension grooves 410, and water is temporarily stored in the extension grooves 410, further increasing the water storage capacity.

[0046] Specifically, four extension grooves 410 are provided. Thus, by providing four extension grooves 410 at the lower side of the water storage tank 400, water in the water storage tank 400 can flow into the extension grooves 410, and water is temporarily stored in the extension grooves 410, further increasing the water storage capacity.

[0047] Optionally, each extension groove 410 is provided with a partition bar 420. In this way, the space in the extension groove 410 is divided by the partition bar 420, so that the water flowing into the extension groove 410 is divided by the partition bar 420, and the partition bar 420 reduces the shaking of the water in the extension groove 410. It can also increase the contact area with water and improve adhesion.

[0048] Optionally, a plurality of dividing bars 420 are provided. In this way, the space in the extension groove 410 is divided by the plurality of dividing bars 420, so that the water flowing into the extension groove 410 is divided into a plurality of parts by the dividing bars 420, and the plurality of dividing bars 420 further reduce the shaking of the water in the extension groove 410. The contact area with water can also be increased, thereby improving the adhesion.

[0049] Specifically, two partition bars 420 are provided.

[0050] Optionally, a plurality of water storage tanks 400 are provided along the airflow direction in the air vent cavity 300. Thus, by providing a plurality of water storage tanks 400, the number of times water is intercepted is increased, and the amount of water temporarily stored is also increased. The risk of water flowing to the damper 200 and freezing at the damper 200 is further reduced, ensuring that the damper 200 can be opened and closed normally.

[0051] Specifically, two water storage tanks 400 are provided along the airflow direction in the ventilation cavity 300. Thus, by providing two water storage tanks 400, the number of times water is intercepted is increased, and the amount of water temporarily stored is also increased. The risk of water flowing to the damper 200 and freezing at the damper 200 is further reduced, ensuring that the damper 200 can be opened and closed normally.

[0052] Specifically, the lower side of each water storage tank 400 is provided with an extension groove 410 connected to the water storage tank 400. In this way, the extension groove 410 is provided at the lower side of each water storage tank 400, and the water in each water storage tank 400 can flow into the corresponding extension groove 410, and the water is temporarily stored in the extension groove 410 to increase the water storage capacity.

[0053] Combination Figure 4 As shown, optionally, the upper side wall of the water storage tank 400 is provided with an inclined guide surface 430. In this way, water droplets can flow more smoothly into the water storage tank 400 through the inclined guide surface 430. The risk of water droplets directly dripping from the upper side wall of the water storage tank 400 to the lower side wall of the water storage tank 400 is reduced, and water splashing is reduced.

[0054] Specifically, the upper side wall of each water storage tank 400 is provided with an inclined guide surface 430. In this way, the upper side wall of each water storage tank 400 guides water droplets to flow into the water storage tank 400 through the corresponding inclined guide surface 430, making the water flow smoother. The risk of water droplets directly dripping from the upper side wall of the water storage tank 400 to the lower side wall of the water storage tank 400 is reduced, and the splashing of water is reduced.

[0055] Optionally, the lower side wall of the water storage tank 400 is inclined downward toward the inside of the water storage tank 400. In this way, the amount of water stored at the bottom of the water storage tank 400 is increased.

[0056] Specifically, the lower side wall of each water storage tank 400 is inclined downward toward the inside of the water storage tank 400 .

[0057] Optionally, the length of the depression of the water storage tank 400 toward the inner side wall of the flow ventilation cavity 300 is less than or equal to one half of the wall thickness of the air duct body 100, and greater than or equal to one tenth of the thickness of the air duct body 100. In this way, when the length of the depression of the water storage tank 400 toward the inner side wall of the flow ventilation cavity 300 is greater than one half of the wall thickness of the air duct body 100, the length of the depression is too long, resulting in a low structural strength of the air duct body 100 and a poor thermal insulation effect. When the length of the depression of the water storage tank 400 toward the inner side wall of the flow ventilation cavity 300 is less than one tenth of the thickness of the air duct body 100, the water storage capacity of the water storage tank 400 is small, and the effect of intercepting water is poor. It can be seen from this that the range of the length of the depression of the water storage tank 400 toward the inner side wall of the flow ventilation cavity 300 is less than or equal to one half of the wall thickness of the air duct body 100, and greater than or equal to one tenth of the thickness of the air duct body 100 is more reasonable, so that the structural strength of the air duct body 100 is relatively high and the thermal insulation effect is relatively good. The water storage tank 400 has a relatively large water storage capacity and a better water interception effect.

[0058] Specifically, the length of the water storage tank 400 that is recessed toward the inner wall of the air vent cavity 300 is equal to one sixth of the wall thickness of the air duct body 100. In this way, the structural strength of the air duct body 100 is relatively high, and the heat preservation effect is relatively good. The water storage tank 400 also has a relatively large amount of water storage, and the water interception effect is better.

[0059] Combination Figure 5 and Figure 6 As shown, in one embodiment, the air duct assembly further includes: a water absorbing member 500. The water absorbing member 500 is disposed below the water storage tank 400 and connected to the inner side wall of the air flow passage cavity 300. In this way, by providing the water absorbing member 500 below the water storage tank 400, after the water in the water storage tank 400 overflows, the water flows toward the bottom of the water storage tank 400 to the water absorbing member 500, and the water absorbing member 500 absorbs the outflowing water, thereby reducing the risk of water flowing to the damper 200 and freezing at the damper 200, and ensuring that the damper 200 can be opened and closed normally.

[0060] Optionally, the upper side of the water absorbent 500 extends to the edge of the water storage tank 400. In this way, the upper side of the water absorbent 500 is closer to the water storage tank 400, and the distance for the overflowing water droplets to flow to the water absorbent 500 is shorter. When water contacts the water absorbent 500, the speed of the water is slower, reducing the risk of water splashing, so that the water absorbent 500 can better absorb water.

[0061] Specifically, the water absorbing member 500 is a water absorbing fabric strip 510. Thus, the water absorbing fabric strip 510 has a better water absorbing effect and a lower manufacturing cost.

[0062] Optionally, the length of the water absorbent 500 protruding from the inner side wall of the air flow vent cavity 300 is less than or equal to one-half of the length of the water storage tank 400 being recessed toward the inner side wall of the air flow vent cavity 300, and greater than or equal to one-seventh of the length of the water storage tank 400 being recessed toward the inner side wall of the air flow vent cavity 300. In this way, in the case where the length of the water absorbent 500 protruding from the inner side wall of the air flow vent cavity 300 is greater than one-half of the length of the water storage tank 400 being recessed toward the inner side wall of the air flow vent cavity 300, the water absorbent 500 will occupy too much space in the air flow vent cavity 300. In the case where the length of the water absorbent 500 protruding from the inner side wall of the air flow vent cavity 300 is less than one-seventh of the length of the water storage tank 400 being recessed toward the inner side wall of the air flow vent cavity 300, the amount of water absorbed by the water absorbent 500 is relatively small. It can be seen that the length of the water-absorbing member 500 protruding from the inner wall of the convection ventilation cavity 300 is less than or equal to one-half of the length of the water storage tank 400 recessed toward the inner wall of the convection ventilation cavity 300, and is greater than or equal to one-seventh of the length of the water storage tank 400 recessed toward the inner wall of the convection ventilation cavity 300. The range is more reasonable, the space occupied in the convection ventilation cavity 300 is relatively small, and the water absorption capacity of the water-absorbing member 500 is also relatively large.

[0063] In another embodiment, a water absorbing portion 600 is provided in the water storage tank 400, and the upper side of the water absorbing portion 600 abuts against the upper side wall of the water storage tank 400, and the lower side of the water absorbing portion 600 is higher than the lower side wall of the water storage tank 400. In this way, by providing the water absorbing portion 600 inside the water storage tank 400, water is absorbed by the water absorbing portion 600. The water flowing into the water storage tank 400 is stored at the bottom of the water storage tank 400, and the water in the water storage tank 400 will flow out of the water storage tank 400 when it exceeds a certain height. Therefore, providing the water absorbing portion 600 in the water storage tank 400 can increase the water storage capacity of the water storage tank 400.

[0064] Optionally, the water absorbing part 600 is a water absorbing cotton strip 610, and the water absorbing cotton strip 610 is fixedly connected to the inner wall of the water storage tank 400. In this way, by arranging the water absorbing cotton strip 610 inside the water storage tank 400, the water is absorbed by the water absorbing cotton strip 610, the water absorption speed is faster, and the absorption effect is good.

[0065] Combination Figures 7 to 9As shown, optionally, the air duct body 100 includes: a first cover body 110, a second cover body 120 and a third cover body 130. The second cover body 120 is covered on one side of the first cover body 110, and together with the first cover body 110, encloses a first flow cavity 310; the third cover body 130 abuts against the first cover body 110 and the second cover body 120, and defines a second flow cavity 320, and the air duct cavity 300 is composed of the first flow cavity 310 and the second flow cavity 320 being connected; wherein the damper 200 is assembled in the second flow cavity 320. In this way, the second cover body 120 is covered on one side of the first cover body 110, and the third cover body 130 abuts against the first cover body 110 and the second cover body 120, so that the first flow cavity 310 and the second flow cavity 320 are connected. The damper 200 is assembled in the second circulation cavity 320. When the damper 200 and the cavity wall of the second circulation cavity 320 are sealed, even if a gap appears in the cavity wall of the second circulation cavity 320, since the first circulation cavity 310 is separately enclosed by the first cover body 110 and the second cover body 120, the gap will not extend into the first circulation cavity 310, thereby shortening the extension of the gap and reducing the risk of air leakage.

[0066] In one embodiment, a portion of a side wall of the third cover 130 abuts against the first cover 110, and the remaining portion of a side wall of the third cover 130 abuts against the second cover 120, and the inner side of the third cover 130 defines a second circulation cavity 320. In this way, the damper 200 is assembled in the second circulation cavity 320, that is, assembled in the third cover 130, and then the first cover 110, the second cover 120 and the third cover 130 are assembled together. In the case of sealing between the damper 200 and the cavity wall of the second circulation cavity 320, since the third cover 130 is an integrated structure, there will be no gap in the cavity wall of the second circulation cavity 320. The second circulation cavity 320 enclosed by the first cover 110 and the second cover 120 will not be affected by the gap, thereby reducing the risk of air leakage.

[0067] Optionally, a first splicing portion 710 is provided between the first cover 110 and the third cover 130 to splice the first cover 110 and the third cover 130; a second splicing portion 720 is provided between the second cover 120 and the third cover 130 to splice the second cover 120 and the third cover 130. In this way, the first cover 110 and the third cover 130 are spliced ​​by the first splicing portion 710, and the second cover 120 and the third cover 130 are spliced ​​by the second splicing portion 720, so as to improve the stability of the connection.

[0068] Optionally, the first joint portion 710 is a first protrusion 711, one end of the first protrusion 711 is fixedly connected to the first cover body 110, and one end of the first protrusion 711 facing away from the first cover body 110 extends into the second flow cavity 320 and abuts against its cavity wall. In this way, the first protrusion 711 extends into the second flow cavity 320 and abuts against its cavity wall, the contact area is larger, and the connection stability is higher.

[0069] Optionally, the second joint portion 720 is a second protrusion 721, one end of the second protrusion 721 is fixedly connected to the second cover body 120, and one end of the second protrusion 721 facing away from the second cover body 120 extends into the second flow cavity 320 and abuts against its cavity wall. In this way, the second protrusion 721 extends into the second flow cavity 320 and abuts against its cavity wall, with a larger contact area and higher connection stability.

[0070] In another embodiment, the first cover 110 abuts against one side wall of the third cover 130, the second cover 120 abuts against another adjacent side wall of the third cover 130, and a portion of the second cover 120 and the third cover 130 enclose a second circulation cavity 320. In this way, the damper 200 can be first assembled in one of the third cover 130 and the portion corresponding to the second cover 120 and the third cover 130, and then the other cover is assembled, and then the damper 200 is assembled into the second circulation cavity 320. The assembly process is more intuitive and simple, reducing the risk of damaging the cavity wall of the second circulation cavity 320. When sealing is performed between the damper 200 and the cavity wall of the second circulation cavity 320, even if a gap appears between the second cover body 120 and the third cover body 130, since the first circulation cavity 310 is separately enclosed by the first cover body 110 and the second cover body 120, and the first cover body 110 and the third cover body 130 are separately arranged, the gap will not extend into the first circulation cavity 310, thereby shortening the extension of the gap and reducing the risk of air leakage.

[0071] Optionally, part of one side wall of the second cover 120 is covered on one side of the first cover 110, and the rest of one side wall of the second cover 120 is in contact with the third cover 130. In this way, the first cover 110 and the third cover 130 are assembled on the same side wall of the second cover 120, and the assembly process is more intuitive and simpler.

[0072] In some embodiments, a refrigerator includes: an air duct assembly as in any of the above embodiments.

[0073] The refrigerator provided by this embodiment includes the air duct assembly in any of the above embodiments, and a water storage tank 400 is provided on the inner wall of the air flow vent cavity 300. When there is water on the inner wall of the air flow vent cavity 300, the water flows into the water storage tank 400 along the inner wall of the air flow vent cavity 300, and the water storage tank 400 intercepts water droplets and temporarily stores the water, thereby reducing the risk of water flowing to the damper 200 and freezing at the damper 200, and ensuring that the damper 200 can be opened and closed normally. The cost of opening the water storage tank 400 is low, and the power consumption of the operation will not be increased. In addition, the air flow circulating in the air flow vent cavity 300 will dry the water in the water storage tank 400, so that the water storage tank 400 can intercept water droplets and temporarily store water again.

[0074] The above description and the accompanying drawings sufficiently illustrate the embodiments of the present disclosure to enable those skilled in the art to practice them. Other embodiments may include structural and other changes. The embodiments represent only possible variations. Unless explicitly required, individual components and functions are optional, and the order of operations may vary. Portions and features of some embodiments may be included in or replace portions and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
