[0021] In the following, exemplary embodiments of the present invention will be described in more detail with reference to the drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention is not limited to the embodiments described herein, but can be realized in various forms. On the contrary, these embodiments are provided to better understand the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0022] Fig. 1 is a schematic structural diagram of a aging compartment for a refrigerator according to an embodiment of the present invention, and Fig. 2 is a schematic structural exploded view of the aging compartment for a refrigerator according to an embodiment of the present invention. The aging compartment for a refrigerator 100 of the present invention may generally include a drawer 200, a top cover plate 300 and an air circulation unit 400.

[0023] In this embodiment, the drawer 200 is configured to be pulled out into the interior of the refrigerator, its upper end is open to form a top opening for putting in and taking out food, and the rear wall panel 210 of the drawer 200 is provided with an exhaust port 211 and a return air port 212. The top cover panel 300 is disposed above the drawer 200, and closes the top opening of the drawer 200 when the drawer 200 is fully inserted into the interior of the refrigerator, and defines a maturing space together with the drawer 200. The air circulation unit 400 is disposed behind the rear wall panel 210 of the drawer 200, and is configured so that air enters the maturing space via the exhaust port 211 and is then blown out from the return air port 212, thereby completing the air circulation in the maturing space.

[0024] In the aging compartment 100 of the present invention, the drawer 200 and the top cover plate 300 are engaged with each other to define an independent aging space. The rear wall plate 210 of the drawer 200 is provided with an exhaust port 211 and a return port 212, and an air circulation unit 400 is arranged behind the rear wall plate 210 of the drawer 200. The air circulation unit 400 realizes air circulation in the aging space, providing an aging environment that can achieve a food dry aging, and allows dry aged food to be made at home. The air circulation unit 400 is arranged behind the drawer 200, and does not affect the internal structure of the drawer 200 and is not restricted by the movement of the drawer 200, which can be more in line with the user's usage habits.

[0025] In some embodiments, as shown in FIG. 2, the airflow circulation unit 400 includes a fan frame 410 and a fan 420 .

[0026] In this embodiment, the fan frame 410 is disposed behind the exhaust port 211, and the fan 420 is disposed within the fan frame 410, and is used to return the airflow in the aging space from the exhaust port 211 to the aging space after it is blown out from the return air port 212. Specifically, the exhaust port 211 has a rectangular shape and is formed by protruding backward from the rear wall panel 210 of the drawer 200. The fan frame 410 is tightly attached to the rear side of the exhaust port 211, so that the airflow in the fan frame 410 is returned from the exhaust port 211 to the aging space under the action of the fan 420.

[0027] The airflow circulation unit 400 of this embodiment includes a fan frame 410 arranged behind the exhaust port 211 and a fan 420 arranged within the fan frame 410, which effectively sends the airflow within the fan frame 410 gently back from the exhaust port 211 into the aging space, improves the air outlet efficiency of the exhaust port 211, and thereby enhances the dry aging effect.

[0028] In some embodiments, a return air vent 212 is provided above the exhaust vent 211. The air circulation unit 400 further includes a return air cover 430, which extends forward and upward from the top of the fan frame 410 to the return air vent 212, so as to realize that the airflow blown out from the return air vent 212 by the action of the fan is introduced into the fan frame 410. Specifically, the return air vent 212 is an elongated shape opened at the top position of the rear wall panel 210 of the drawer 200, the return air cover 430 is an elongated shape corresponding to the return air vent 212, and the return air vent 212 can be tightly fitted to the intake part of the return air cover 430, thereby realizing a tight connection.

[0029] The air circulation unit 400 of this embodiment includes a return air cover 430 extending forward and upward from the top of the fan frame 410 to the return air vent 212, which determines the flow direction of the airflow blown out of the return air vent 212, and ensures that the airflow in the aging space, after being blown out of the upper return air vent 212, enters the fan frame 410 through the blocking action of the return air cover 430. Because the fan 420 is disposed in the fan frame 410, the airflow blown out of the return air vent 212 can quickly enter the fan frame 410 through the return air cover 430 through the promoting action of the fan 420, improving the efficiency of air circulation, thereby further enhancing the dry aging effect. By locating the return air port 212 above the exhaust air port 211, it is ensured that the airflow in the aging space is blown out from the upper return air port 212 and then returned to the aging space from the lower exhaust air port 211, the direction of airflow circulation in the aging space is determined, and the stability of the airflow flowing in the aging space is further ensured, thereby improving the dry aging effect.

[0030] In some embodiments, when the drawer 200 is fully pushed into the cabinet, the airflow circulation unit 400 is connected to the exhaust port 211 and the return port 212 of the drawer 200 and the airflow circulation unit 400 operates normally, and when the drawer 200 is pulled out, the connection between the airflow circulation unit 400 and the exhaust port 211 and the return port 212 is cut off.

[0031] In some embodiments, the fan 420 is an axial fan. As shown in FIG. 2, the exhaust port 211 is provided below the return air port 212, and the air guide unit 500 is provided at the exhaust port 211, and the air guide unit 500 is configured to send the airflow blown out from the axial fan diagonally downward into the maturation space. Specifically, the axial fan blows air from the rear to the front, and the air guide unit 500 is provided at the exhaust port 211, and may be a louver-shaped unit that is provided in a low front and high rear, so that the axial fan blows the airflow diagonally downward. In this embodiment, the air guide unit 500 is configured to send the airflow that enters the maturation space from the exhaust port 211 diagonally downward, so that the airflow that enters the maturation space reaches each position in the maturation space after blowing on the surface of the food. Due to the blocking action of the inner wall of the drawer and the inner wall of the top cover plate, the airflow in the fermentation space is blown out from the return air vent 212 at the top of the fermentation space, completing the airflow circulation in the fermentation space.

[0032] In some embodiments, as shown in Fig. 1 and Fig. 2, a first ventilation opening 412 communicating with a storage compartment of a refrigerator is provided on a side wall 411 of the fan frame 410, so that airflow in the storage compartment is sucked into the fan frame 410 through the first ventilation opening 412 by the action of the fan 420 and allowed to enter the fermentation space through the exhaust port 211 and the air guide part 500. Specifically, a first ventilation opening 412 communicating with a storage compartment of a refrigerator can be provided on both side walls 411 of the fan frame 410, so that airflow in the storage compartment is allowed to properly enter the fan frame 410 through the first ventilation opening 412 by the action of the fan 420, and enter the fermentation space through the exhaust port 211, thereby realizing gas exchange between the fermentation space and the storage compartment.

[0033] Furthermore, the second ventilation openings 240 communicating with the storage compartment are provided in both front regions of the side walls on both lateral sides of the drawer 200, so that the high humidity air current in the aging space is allowed to flow into the storage compartment from the second ventilation openings 240 by the action of the fan 420. In this way, the low humidity air current that enters the aging space from the storage compartment flows sufficiently through the entire aging space, and then returns to the storage compartment via the second ventilation openings 240.

[0034] The aging compartment 100 in the above embodiment is provided with a first ventilation opening 412 and a second ventilation opening 240 communicating with the storage compartment, and the airflow in the storage compartment can enter the fan frame 410 from the first ventilation opening 412 by the action of the fan 420, enter the aging space through the exhaust opening 211, and then be discharged to the storage compartment through the second ventilation opening 240. In this way, air circulation between the aging space and the storage compartment is realized, thereby reducing the humidity in the aging compartment 100.

[0035] Furthermore, the storage compartment may be a refrigerator compartment, and the aging compartment 100 is disposed in the refrigerator compartment, and the first ventilation port 412 connects the aging compartment 100 and the refrigerator compartment, allowing a certain air exchange between the refrigerator compartment and the aging compartment 100, thereby controlling the humidity in the aging space. For example, the humidity in the aging space is controlled to 50%-90%, more preferably 55%-85%. In some more specific embodiments, it is more preferably controlled to 70%, so as to enhance the dry aging effect.

[0036] In some embodiments, the aging compartment 100 for a refrigerator further includes a humidity sensor for detecting the humidity in the aging space. The humidity sensor can monitor whether the humidity in the aging space is within a required humidity range. What is to be explained is that the specific location of the humidity sensor is not shown in the figures. As can be understood by those skilled in the art, the humidity sensor may be provided on the top cover plate 300 or on the drawer 200. In some more specific embodiments, it is more preferable that the humidity sensor is provided on the top cover plate 300. In addition, the airflow flow area of ​​the first ventilation opening 412 can be adjusted according to the humidity in the aging space, thereby changing the gas exchange rate between the aging space and the storage compartment. For example, an airflow opening / closing device (not shown) is disposed on the first ventilation opening 412, and the airflow opening / closing device is configured to adjust the airflow flow area of ​​the first ventilation opening 412 according to the humidity. In detail, the air vent opening and closing device adjusts the airflow flow area of ​​the first ventilation opening 412 according to the humidity, and controls the gas exchange rate between the aging space and the storage compartment to a range of 5% to 30%. Such an air vent opening and closing device can be realized by those skilled in the art, and will not be described repeatedly in this specification. The aging compartment 100 of this embodiment is provided with a humidity sensor, and can adjust the airflow flow area of ​​the first ventilation opening 412 according to the humidity, thereby avoiding the problem of the humidity in the aging space being too high after fresh food is placed in the aging compartment 100, and realizing the humidity of the aging space to be maintained within a required humidity range, thereby achieving a better dry aging effect.

[0037] Also, in one optional embodiment of the above embodiment, the airflow area of ​​the second ventilation opening 240 may be set to be adjusted in synchronization with the airflow area of ​​the first ventilation opening 412. Or, in another optional embodiment of the above embodiment, the maturation compartment 100 further includes a cooling air outlet 600 for blowing a cooling airflow of a specified temperature into the maturation space, and the second ventilation opening 221 is always fully open, and the cooling airflow is returned after passing through the second ventilation opening 221.

[0038] In some embodiments, the exhaust port 211 is located in the center of the rear wall panel 210 of the drawer 200, and the second ventilation port 240 is provided in the front region of the side wall panels on both lateral sides of the drawer 200, so that the airflow entering the fan frame 410 from the storage compartment enters the maturation space through the exhaust port 211 and is then blown out from the second ventilation ports 240 on both sides of the front of the drawer, thereby realizing that the airflow entering the maturation space from within the storage compartment via the fan frame 410 and the exhaust port 211 can reach each position in the maturation space uniformly.

[0039] In some specific embodiments, the height position of the geometric center of the second ventilation opening 240 is higher than the height position of the geometric center of the exhaust opening 211. This improves the speed of humidity adjustment in the aging compartment 100. In some more specific embodiments, the bottom side of the second ventilation opening 240 is higher than the top side of the exhaust opening 211. In other more specific embodiments, the lower segment of the second ventilation opening 240 and the upper segment of the exhaust opening 211 partially overlap. In addition, the ventilation area of ​​the second ventilation opening 240 is set to be basically the same as the ventilation area of ​​the first ventilation opening 412. This makes the air circulation between the storage compartment and the aging space more stable, further improves the uniformity of the air circulation, and further enhances the dry aging effect.

[0040] Fig. 3 is a plan view of a ripening compartment for a refrigerator according to one embodiment of the present invention with a top cover plate removed, and Fig. 4 is a cross-sectional view of the ripening compartment for a refrigerator according to one embodiment of the present invention taken along section line A-A' in Fig. 1. In some embodiments, as shown in Figs. 3 and 4, the ripening compartment 100 of the present invention further comprises a shelf 700 and a tray 800.

[0041] In this embodiment, the shelf 700 is removably disposed within the drawer 200 and receives food items such that the air current circulating within the maturation space can flow both above, below, and to the left and right of the food items. That is, food items can be placed on the shelf 700 such that the air current circulating within the maturation space can blow on each of the above, below, left, and right of the food items.

[0042] The shelf 700 in this embodiment is removably arranged, which facilitates users to clean it by themselves, while making the production assembly easier and reducing the production cost of the aging compartment 100. The shelf 700 receives the food and realizes the direct contact between the food surface and the airflow circulating in the aging space, which enhances the evaporation speed of the moisture of the outer layer of the food, thereby promoting the rapid air-drying of the food surface to form a protective layer, making the flavor of the food richer and more saturated, and achieving a better dry aging effect.

[0043] In some more specific embodiments, the shelf 700 includes a receiving surface 710 and a support member 720. As shown in FIG. 3, the receiving surface 710 is a mesh structure, and the projected area of ​​the receiving surface 710 in a horizontal plane is 0.8 to 0.99 times the area of ​​the bottom of the drawer 200. This ensures that the space for placing food is sufficiently large, and the airflow in the vertical and horizontal directions of the food is more sufficient, thereby further ensuring that the surface of the food can directly contact the airflow circulating in the aging space in any direction. The projected area of ​​the receiving surface 710 in a horizontal plane is set to be sufficiently large, which increases the development area of ​​the food and promotes the stretching of the muscle fibers inside the food, thereby making the texture after aging softer and achieving a better aging effect. Preferably, the receiving surface 710 extends along the horizontal direction. This allows the airflow to flow in both the vertical and horizontal directions of the food, increasing the uniformity of the airflow in the vertical direction of the food, and improving the air drying speed of the food.

[0044] As shown in FIG. 4, the support member 720 supports the receiving surface 710 on the bottom of the drawer 200, and the height of the support member 720 is 1 cm to 3 cm, and in some embodiments, more preferably 1.5 cm to 2.5 cm. In some more specific embodiments, it is more preferably 2 cm. The support member 720 is arranged at a suitable height so that there is sufficient airflow space under the food received on the shelf 700, which improves the airflow speed on the food surface and reduces the storage space occupied in the maturing space to a certain extent. Preferably, the support member 720 is formed with the receiving surface 710 recessed vertically downward, which is integrally molded, and has a simple structure and reduces the production cost.

[0045] In some embodiments, the tray 800 is removably positioned below the shelf 700 to collect dripping juices during the aging process of the food received on the shelf 700, and prevent the dripping juices from contaminating the internal environment of the aging compartment 100 by concentrating and flowing at the bottom of the drawer 200. In addition, the tray 800 is a removable part, which makes it easy for users to clean it themselves, makes production assembly easier, and reduces the production cost of the aging compartment 100.

[0046] 2, the top cover plate 300 includes a top wall 310 and a skirt 320 formed by folding downward, and the skirt 320 is configured so that the bottom surface of the skirt 320 closely contacts the two side walls of the drawer 200 and the top surface of the rear wall plate 210 when the drawer 200 is fully pushed into the chamber. This further ensures that the top cover plate 300 can close the top opening of the drawer 200 and define an independent aging space together with the drawer 200 when the drawer 200 is pushed into the chamber. In addition, the structure of the drawer 200 and the top cover plate 300 is simple and suitable for assembly into various different types of refrigerator bodies, improving the versatility of the aging compartment 100.

[0047] In some more specific embodiments, as shown in Fig. 4, the skirt 320 includes a first skirt side wall 321 and a second skirt side wall 322 located on both sides of the top wall 310, and a skirt rear wall 323 located on the rear side of the top wall 310. Specifically, the first skirt side wall 321 and the second skirt side wall 322 are both wedge-shaped with a narrow front and a wide rear. The first side wall panel 220 and the second side wall panel 230 on both lateral sides of the drawer 200 are configured as a high-front and low-rear structure that fits the first skirt side wall 321 and the second skirt side wall 322, respectively, so that when the drawer 200 is fully pushed into the interior, the bottom surface of the skirt 320 tightly contacts the top surface of the wall panel of the drawer 200, and the drawer 200 can be smoothly pulled out from the interior of the refrigerator. Preferably, the first side wall panel 220 and the second side wall panel 230 of the drawer 200 are arranged to fit the first skirt side wall 321 and the second skirt side wall 322, respectively, to improve the sealing of the aging space. It should be noted that the front and rear mentioned in this specification are defined with respect to the cabinet of the refrigerator, and the direction toward which the opening of the cabinet faces is the front direction.

[0048] In one alternative embodiment of the above embodiment, the maturation compartment 100 is further provided with a cooling air outlet 600. As shown in FIG. 1 and FIG. 2, the skirt rear wall 323 protrudes backward to form the cooling air outlet 600. The cooling air outlet 600 is used to blow a cooling airflow of a specified temperature into the maturation space, thereby controlling the temperature of the maturation space to 0-4°C. In this embodiment, a temperature sensor (not shown) for detecting the temperature in the maturation space is further arranged in the maturation compartment 100. For example, the temperature sensor is arranged in the top cover plate 300, the drawer 200 or other positions in the maturation space to realize monitoring of the temperature in the maturation space. For example, when the temperature sensor detects that the temperature in the maturation space is equal to or higher than a predetermined temperature, the cooling air outlet 600 blows a cooling airflow of a specified temperature into the maturation space until the temperature of the maturation space is controlled to 0-4°C.

[0049] The aging compartment 100 of this embodiment has the cooling air supply vent 600 and a temperature sensor, thereby realizing real-time monitoring and control of the temperature in the aging space and maintaining a fixed temperature to create an aging environment suitable for dry aging of food. The cooling air supply vent 600 is provided in the top cover plate 300, which prevents the cooling air supply form from affecting the internal structure of the drawer 200 and prevents the cooling air supply form from being restricted by the movement of the drawer 200, thereby improving the versatility of the drawer 200, simplifying the assembly of the aging compartment 100, and reducing the manufacturing cost.

[0050] 5 is a schematic structural diagram of a refrigerator 900 according to an embodiment of the present invention. The refrigerator 900 of the present invention may generally include a cabinet 910 and a fermentation compartment 100 disposed within the cabinet.

[0051] A cooling air duct 920 for supplying a cooling airflow is defined in the cabinet 910. At least one air outlet 921 is provided in the cooling air duct 920 for blowing the cooling airflow out of the cooling air duct 920. The aging compartment 100 is provided with a cooling air outlet 600. At least a part of the at least one air outlet 921 is connected to the cooling air outlet 600. In a specific application, as shown in FIG. 2 and FIG. 3, the cooling air outlet 600 in the embodiment of the present invention is formed by the skirt rear wall 323 of the top cover plate 300 protruding backward. As shown in FIG. 5, the wall part of the cooling air outlet 600 is fitted to the outside of the air outlet 921, so that the cooling air duct 920 can deliver a cooling airflow of a specified temperature into the aging compartment 100 through the cooling air outlet 600. In this way, regulation of the temperature within the maturation compartment 100 is achieved, for example the temperature within the maturation compartment 100 is controlled to 0-4°C.

[0052] The refrigerator 900 of the embodiment of the present invention has an aging compartment 100 and a cooling air duct 920 that supplies cooling airflow at a specified temperature to the aging compartment 100, creating an aging environment that enables dry aging of food, and allowing people to make their own aged food at home.

[0053] In some more specific embodiments, a storage compartment 930 is defined in the body 910 of the refrigerator 900, and the aging compartment 100 is disposed in the storage compartment 930.
