[0027] See also Figure 1-2 , is a schematic structural diagram of a drawer assembly 100 and an air duct structure 200 in a refrigerator provided in one embodiment of the present invention, wherein the air duct structure 200 is used to supply air to the drawer assembly 100.

[0028] Preferably, the air duct structure 200 includes a first air outlet 201 and a second air outlet 202 which are arranged in cooperation with the drawer assembly 100. The drawer assembly 100 includes a drawer body 10 and a drawer cover 20. The drawer cover 20 is provided with an air inlet 203, and the air inlet 203 is connected to the inner and outer sides of the drawer body 10. The first air outlet 201 blows air toward the top of the drawer cover 20, and the second air outlet 202 blows air toward the air inlet 203.

[0029] Among them, Figure 3As shown, the first air outlet 201 is a main air outlet, and its function is to ensure that cold air always blows over the drawer cover 20 to prevent moisture on the outer surface from causing frost. The second air outlet 202 is an auxiliary air outlet, and its functions are twofold: first, to supply air to the entire drawer body 10 to achieve the purpose of cooling; second, to further blow the inner side of the drawer cover 20 to prevent moisture from accumulating on the inner side of the drawer cover 20 and causing frost.

[0030] Preferably, the first air vent 201 and the second air vent 202 are arranged adjacent to each other, the wind direction angle of the first air vent 201 is different from the wind direction angle of the second air vent 202, the first air vent 201 is higher than the upper surface of the drawer cover 20, and the first air vent 201 blows air toward the upper surface of the drawer cover 10.

[0031] Combination Figure 4-5 As shown, the first air outlet 201 and the second air outlet 202 should have different wind direction angles, and the downward inclination angle of the second air outlet 202 should be greater than that of the first air outlet 201, so that air can be blown to the outside of the drawer cover 10 while blowing air toward the inside of the drawer body 10. More specifically, the first air outlet 201 is vertically arranged above the drawer cover 20 to ensure that air is blown toward the upper surface of the drawer cover 10.

[0032] The first air outlet 201 can be formed as a plurality of first holes arranged at intervals to make the air flow uniform, or as one air outlet to increase the air volume; the second air outlet 202 can be formed as a plurality of second holes arranged at intervals to make the air flow uniform, or as one air outlet to increase the air volume. The first air outlet 201 and the second air outlet 202 can also be connected and arranged, and the size and position of the first hole and the second hole are not limited, and the key point is that as long as the wind direction condition is met, it can be used.

[0033] Preferably, the wind direction angle of the first air outlet 201 is set to horizontal blowing, and a wind shield 210 is arranged above the first air outlet 201 .

[0034] When the first air outlet 201 is set to blow horizontally, it is beneficial for the wind to diffuse farther in the horizontal direction, so that the side of the drawer cover 20 away from the air duct structure 200 can also be blown by the wind; at the same time, a horizontal wind shield 210 is set to guide more wind to blow downward to the upper surface of the drawer cover 20, thereby reducing the upward diffusion. The second air outlet 202 is set to blow obliquely.

[0035] In other embodiments, the first air outlet 201 can also be directly set to be tilted downward at a certain angle to ensure that the wind direction is toward the drawer cover 20 and reduce upward diffusion. The downward tilt angle should not be too large, otherwise it will be detrimental to the forward flow of wind, and most of the wind from the first air outlet 201 may even be blown into the inside of the drawer body 10.

[0036] Preferably, the drawer cover 20 includes an inclined rear wall 22, the air inlet 203 is arranged on the rear wall 22, and the second air inlet 202 is directly opposite to the air inlet 203; in this way, the second air inlet 202 supplies air directly to the air inlet 203, so as to cool the interior of the drawer body 10 and blow air on the inner side of the drawer cover 20 to prevent frost.

[0037] In a specific embodiment, the drawer cover 20 includes a horizontal top wall 21 and a rear wall 22 extending obliquely backward from the rear end of the top wall 21 , and the inclination angle of the second air outlet 202 is equal to the inclination angle of the rear wall 22 , so that the second air outlet 202 faces the rear wall 22 .

[0038] In a specific embodiment, the drawer assembly 100 is spaced a distance apart from the air duct structure 200 in the horizontal direction. In other words, there is a gap between the drawer assembly 100 and the air duct structure 200 in the front-to-back direction. The rear wall 22 and the second air outlet 202 are located at the same height in the vertical direction. In other words, the rear wall 22 and the second air outlet 202 are basically aligned in the front-to-back direction, and at least the air inlet 203 of the rear wall 22 is aligned with the second air outlet 202 in the front-to-back direction. The vertical height of the rear wall 22 is greater than or equal to the vertical height of the second air outlet 202, and the vertical height of the air inlet 203 falls within the vertical height range of the second air outlet 202, which is conducive to the wind fully blowing into the air inlet 203.

[0039] The rear wall 22 and the second air outlet 202 are located at the same height, and a notch 220 is provided at the lower end of the rear wall 22, and the notch 220 is 5-6 mm away from the rear end of the drawer body; specifically, the distance L1 between the upper wall surface of the notch 220 and the top surface of the drawer body 10 is between 5-6 mm; Figure 5 As shown, the notch 220 forms a gap with the drawer body 10 along the vertical direction, and can also be used for the second air outlet 202 to supply air into the drawer body 10 to ensure uniform air supply.

[0040] Preferably, the air inlet 203 includes a plurality of evenly and spaced circular holes, each of which has a diameter range of 4-5 mm, and a spacing range of 9-11 mm between adjacent circular holes, more preferably 10 mm; the turbulent wind coming out of the second air outlet 202 is throttled so that it is more uniform when entering the drawer body 10, which is beneficial to the uniformity of temperature inside the drawer body 10.

[0041] Preferably, the drawer cover 20 is disposed on the top of the drawer body 10, and the distance between the drawer cover 20 and the drawer body is 3-5 mm; the distance L2 between the bottom surface of the drawer cover 20 and the top surface of the drawer body 10 is between 3-5 mm. Figure 6-8As shown, the drawer body 10 can be pulled out of the refrigerator, and the drawer cover 20 will not be taken out with the drawer body 10. The drawer body 10 and the drawer cover 20 are fixed independently of each other, and the drawer body 10 can slide relative to the drawer cover 20.

[0042] The drawer cover 20 has a cover side wall 23 with a gradually changing height to form an inclined bottom surface of the drawer cover 20 that is higher in the front and lower in the back. At the same time, the drawer body 10 also has a body side wall 11 with a gradually changing height to form an inclined top surface of the drawer body 10 that is higher in the front and lower in the back. The two have the same inclination angle. In this way, the inclined bottom surface of the drawer cover 20 is parallel to the inclined top surface of the drawer body 10, and the two are 3-5mm apart. The two opposite surfaces that are higher in the front and lower in the back and parallel to each other are conducive to ensuring that the customer can smoothly pull out or push the drawer body 10 forward, and the distance between them will not be too far to prevent affecting the refrigeration or freezing effect.

[0043] The drawer assembly 100 includes a drawer front panel 30 arranged in front of the drawer cover 20 and the drawer body 10, and the drawer front panel 30 is 1-3 mm away from the drawer cover 20 in the front-to-back direction; the rear end of the drawer front panel 30 is 1-3 mm away from the front end of the drawer cover 20 to prevent the two from colliding when being pulled out.

[0044] The drawer front plate 30 is used to seal the front of the drawer body 10 and to form a drawer handle, so that the user can apply force to pull out or push in the drawer body 10. The drawer front plate 30 and the drawer body 10 can be formed in one piece or in a separate piece. A distance L3 is provided between the drawer front plate 30 and the drawer cover plate 20 to prevent the drawer front plate 30 from hitting the drawer cover plate 20 when being pulled out or pushed in, thereby affecting the user experience and causing damage to both. At the same time, the distance between the drawer front plate 30 and the drawer cover plate 20 should not be too large to prevent cold air leakage from affecting the refrigeration or freezing effect.

[0045] Preferably, the drawer cover 20 includes a cover body 24 and a moisturizing module 25. Figure 9-10 As shown, the cover body 24 is provided with the top wall 21 , the rear wall 22 and the side wall 23 .

[0046] The middle of the cover body 24 is formed as a through region 240 with a step structure, the moisturizing module 25 is disposed in the through region 240 , and the upper surface of the moisturizing module 25 is coplanar with the upper surface of the cover body 24 .

[0047] In a specific embodiment, the drawer assembly 100 is a temperature-variable drawer assembly with a temperature-adjusting function, and a refrigeration and freezing moisturizing module 25 is embedded in the drawer cover 20. The moisturizing module 25 is usually humid and more prone to frost. Therefore, the first air outlet 201 mainly blows air toward the upper surface of the drawer cover 20 to ensure that cold air always blows over the moisturizing module 25 to prevent the outer surface of the moisturizing module 25 from being too humid and frosted.

[0048] At the same time, the through area 240 with the step structure can make the outer surface of the drawer assembly 100 smoother, which is conducive to the blowing of cold air; the single-layer or multi-layer step structure can also enhance the structural strength of the cover body 24.

[0049] Preferably, a reinforcement edge 243 is vertically provided at the end of the cover body 24 to enhance the structural strength of the cover body 24 .

[0050] Since the middle area of ​​the cover body 24 is penetrated to set the moisturizing module 25, the cover body 24 made of plastic material formed by injection molding has a weak structural strength and is easily deformed, causing it to fall off the refrigerator inner tank. Therefore, a reinforcing edge 243 structure with upper and lower flanges is added to the front end of the cover body 24, and a reinforcing structure can also be set in other areas of the cover body 24.

[0051] Combination Figure 8-10 As shown, when the front end of the cover body 24 is provided with a downwardly turned reinforcing edge 243, the distance between the reinforcing edge 243 and the drawer front plate 30 is the distance L3 between the drawer front plate 30 and the drawer cover 20 along the front-to-back direction. Therefore, the reinforcing edge 243 structure can also be used to withstand the collision force of the drawer front plate 30 when pulling with transitional force.

[0052] Preferably, a buckle structure 241 is provided between the cover body 24 and the moisturizing module 25 for buckle fixing the two after assembly, and the buckle structure 241 is a buckle protrusion and a buckle groove that cooperate with each other, one of which is provided on the cover body 24, and the other is provided on the moisturizing module 25. In other embodiments, other locking methods such as screws may also be selected.

[0053] A limiting structure 242 is further provided between the cover body 24 and the moisturizing module 25. The limiting structure 242 is a positioning block and a positioning groove that cooperate with each other, one of which is provided on the cover body 24 and the other is provided on the moisturizing module 25. It is used for limiting the position during assembly to prevent excessive installation.

[0054] The beneficial effects of the present invention are at least that: the air duct structure 200 is provided with a first air outlet 201 to blow air toward the top of the drawer cover 20 to prevent frost on the outer side of the drawer cover 20, and further, prevent frost on the outer surface of the moisturizing module 25 due to excessive moisture; the air duct structure 200 is also provided with a second air outlet 202 to blow air toward the air inlet 203 of the drawer cover, which can not only cool the inside of the drawer body 10 but also prevent frost on the inner side of the drawer cover 20, and further, prevent frost on the inner surface of the moisturizing module 25 due to excessive moisture; the drawer cover 20 is 3-5mm away from the drawer body in the vertical direction, which is conducive to the smooth pulling and pulling of the drawer body 10 and ensures the refrigeration and freezing effect; the drawer front panel 30 is 1-3mm away from the drawer cover 20 in the front-to-back direction to prevent pulling and collision and ensure the refrigeration and freezing effect; the cover body 24 is provided with a step structure and a reinforcing edge 243 to enhance the structural strength.
