Description

[0001] The present invention relates to refrigeration and freezing technology, and more particularly to an aging device for a refrigeration and freezing apparatus and the refrigeration and freezing apparatus. [Background technology]

[0002] Aging is a process in which meat after deacidification is placed in an aging chamber with a constant temperature, humidity, and air velocity to undergo slow, natural fermentation, ultimately producing a deep flavor and improving the tenderness, flavor, juiciness, etc. of the meat. Existing aging devices are generally independent, require the design of special temperature and humidity control devices, and have a relatively complex structure. Furthermore, after the material to be aged is placed in the aging chamber, its bottom is usually in contact with a shelf, and the humidity at the bottom is high. Therefore, if the air velocity at the bottom is insufficient, the high humidity is likely to cause the growth and proliferation of microorganisms, ultimately resulting in the spoilage of the material to be aged.

[0011] Optionally, both the second blowing segment and the third blowing segment are tapered along the airflow direction therein.

[0012] Optionally, an air guide plate is provided adjacent to the outside of some of the air outlets on the upstream side within the second air blowing segment and the third air blowing segment.

[0013] Optionally, the return air vent is a circular air vent, the center of the circle of the return air vent overlaps with the center of the circulation fan, and the diameter of the return air vent is 3 / 4 to 1 times the diameter of the circulation fan; and / or The height of the airflow outlet of the circulation fan is 2 / 3 to 5 / 3 of the diameter of the circulation fan.

[0014] Optionally, the circulation fan includes a blower outlet casing and an impeller disposed in the blower outlet casing, and the top of the blower outlet casing has an arc-shaped structure with a central portion protruding upward.

[0015] According to a second aspect of the present invention, there is further provided a refrigeration / freezing apparatus, a storage body defining a storage chamber for storing items therein; The maturation device according to any of the above solutions, which is used for maturing the material to be maturated therein, comprises a maturation device provided in the storage chamber.

[0016] The aging device of the present invention, when applied to a refrigerator / freezer, can effectively utilize the low-temperature, high-humidity environment within the refrigerator / freezer to promote aging of the aging objects in the aging device, eliminating the need for special temperature and humidity control devices, thereby simplifying the structure of the aging device and reducing its costs.

[0018] Furthermore, the ventilation air duct includes a first ventilation segment at the rear and a second and third ventilation segment on either side, and both the second and third ventilation segments are tapered along the airflow direction within them. By utilizing the tapered overflow area, the phenomenon of the air velocity in the second and third ventilation segments gradually decreasing along the airflow direction is avoided, improving the uniformity of ventilation at various points in the vertical direction of the aging chamber, and achieving a uniform airflow blowing effect on all areas of the vertical surface of the aged material.

[0019] In this way, the material to be aged can be subjected to a uniform airflow blowing effect in both the horizontal and vertical directions, improving the aging effect of the material to be aged.

[0023] The present invention provides a aging device for a refrigeration / freezing device, which is used to age objects within the device. When the aging device of the present invention is applied to a refrigeration / freezing device, it effectively utilizes the low-temperature, high-humidity environment within the device to promote the aging of objects within the device, eliminating the need for special temperature and humidity control devices, thereby simplifying the structure of the aging device and reducing its cost.

[0024] Fig. 1 is a schematic exploded view of the structure of a ripening device according to an embodiment of the present invention, and Fig. 2 and Fig. 3 are schematic cross-sectional views of the ripening device according to an embodiment of the present invention as seen from different directions. Referring to Fig. 1 to Fig. 3, a ripening device 20 for a refrigeration / freezer of the present invention comprises an outer housing 21, an inner housing 22, and a circulation fan 23.

[0025] An aging chamber 221 for accommodating an object to be aged is defined inside the inner housing 22. The outer housing 21 is provided outside the inner housing 22, and at least a portion of the circumferential side wall of the outer housing 21 is provided at a distance from at least a portion of the circumferential side wall of the inner housing 22. A blowing air duct 24 is formed outside the inner housing 22 and inside the outer housing 21. The blowing air duct 24 communicates with the aging chamber 221 via a plurality of air outlets provided in the circumferential side wall of the inner housing 22. The circulation fan 23 is controlled to generate an airflow in the blowing air duct 24 and flow into the aging chamber 221 through the air outlets. The plurality of air outlets are distributed sparsely at the top and densely at the bottom on the circumferential side wall of the inner housing 22.

[0026] That is, the aging device 20 of the present invention has a two-layer structure consisting of an inner housing 22 and an outer housing 21. A aging chamber 221 is defined within the inner housing 22, and a blowing air duct 24 is defined between the inner housing 22 and the outer housing 21. Under the operation of the circulation fan 23, the airflow in the blowing air duct 24 is carried to the aging chamber 221 through air outlets provided on the circumferential side wall of the inner housing 22. Furthermore, the air outlets are distributed sparsely at the top and densely at the bottom on the circumferential side wall of the inner housing 22. That is, the air outlets are distributed sparsely at the top and densely at the bottom, so that more of the airflow in the blowing air duct 24 flows to the bottom of the aging chamber 221 and is blown onto the bottom of the aging object, suppressing the growth and proliferation of microorganisms and avoiding the problem of the aging object being prone to spoilage due to relatively high humidity at the bottom.

[0027] Specifically, the multiple air outlets are distributed in two areas, the upper air outlet and the lower air outlet, on the circumferential side wall of the inner housing 22, and the ratio between the total area of ​​the upper air outlet and the total area of ​​the lower air outlet is preferably between 1:2 and 1:3, which can rationally distribute the air flow flowing through the upper and lower areas of the aging chamber 221. On the one hand, it can ensure a high wind speed in the lower part of the aging chamber 221 to promote evaporation of moisture at the bottom of the aging material, and on the other hand, the air flow can also be blown to other areas of the aging material, thereby achieving a good aging effect.

[0028] In some embodiments, the aging device 20 further includes a cylinder 20a and an open-top drawer 20b formed by an outer housing 21, an inner housing 22, a circulation fan 23, etc. The drawer 20b can be pushed and pulled within the cylinder 20a to form a relatively closed aging chamber 221. At the same time, it is possible to easily access the aging material to the aging chamber 221, improving the user's convenience of operation.

[0029] It should be understood that the air outlets may be distributed in various specific configurations on the circumferential sidewall of the inner housing 22 .

[0030] Specifically, in some embodiments, the multiple air outlets may include multiple vertical air outlets 222 extending vertically and multiple horizontal air outlets 223 extending horizontally. That is, the vertical air outlets 222 and the horizontal air outlets 223 are both bar-shaped air outlets, and the bar-shaped air outlets have a large overflow area, which reduces the airflow resistance of the airflow flowing into the aging chamber 221 and ensures the airflow speed toward the aging target objects. Furthermore, by distributing the vertical air outlets 222 and the horizontal air outlets 223 extending in different directions, uniform or specific airflow in different directions throughout the aging chamber 221 can be achieved.

[0031] Furthermore, the vertical height of the horizontal air outlet 223 is located below the center of the lowest vertical air outlet 222 and above the bottom of the lowest vertical air outlet 222. As a result, air is blown to the upper region of the aging chamber 221 by the vertical air outlet 222, and air is blown to the lower region of the aging chamber 222 by the cooperation of the vertical air outlet 222 and the horizontal air outlet 223, ensuring a larger air flow rate in the lower region of the aging chamber 221 than in the upper region, and enabling air to be blown to target the bottom of the objects to be aged.

[0032] Specifically, the vertical air outlets 222 may be arranged in a single row or in multiple rows, and the horizontal air outlets 223 are arranged in a single row.

[0033] In some embodiments, a wire rack 25 for placing the aging material inside the inner housing 22 is provided, and the wire rack 25 is spaced apart from the bottom plate of the inner housing 22, leaving an airflow space below the wire rack 25, making it easier to blow air onto the underside of the aging material placed on the wire rack 25, and achieving a rapid air-drying effect on the underside of the aging material.

[0034] Specifically, the storage rack 25 has a plurality of hollowed out rope holes formed therein, and the hollowed out storage rack 25 reduces the contact area between the maturation object and the storage rack 25, thereby preventing part of the surface of the maturation object from coming into contact with the airflow and causing it to spoil.

[0035] Furthermore, the height of the horizontal air outlet 223 is equal to or slightly lower than the height of the mounting wire rack 25. This allows the airflow blown into the aging chamber 221 through the horizontal air outlet 223 to be blown toward the bottom of the objects to be aged placed on the mounting wire rack 25, thereby accelerating the aging speed of the objects to be aged.

[0036] In some embodiments, the vertical air outlets 222 and the horizontal air outlets 223 are alternately arranged, thereby ensuring uniform airflow in the ripening chamber 221 in the front-to-back direction.

[0037] Specifically, the vertical air outlets 222 are all the same size, and the horizontal air outlets 223 are all the same size. The vertical air outlets 222 are uniformly distributed, and the horizontal air outlets 223 are uniformly distributed. This ensures uniform airflow within the same height area of ​​the ripening chamber 221.

[0038] In some alternative embodiments, the plurality of air outlets may be distributed in other patterns on the circumferential sidewall of inner housing 22. For example, the plurality of air outlets may be uniformly sized circular air outlets with a lower density of circular air outlets at the top and a higher density of circular air outlets at the bottom.

[0039] In some embodiments, the rear wall 21a and two lateral side walls 21b of the outer housing 21 are spaced apart from the rear wall 22a and two lateral side walls 22b of the inner housing 22, respectively, to form a U-shaped air duct 24. The circulation fan 23 is disposed in the air duct 24, and multiple air outlets are provided on the two lateral side walls 22b of the inner housing 22, respectively. As a result, the airflow in the air duct 24 is transported to the aging chamber 221 through the air outlets provided on the two lateral side walls 22b of the inner housing 22, respectively. That is, the airflow simultaneously flows into the aging chamber 221 from both lateral sides, improving the lateral airflow uniformity of the aging chamber 221 and improving the aging effect of the aged material.

[0040] In some embodiments, the blowing air duct 24 includes a first blowing segment 241 located at the rear of the inner housing 22, and a second blowing segment 242 and a third blowing segment 243 respectively provided on both lateral sides of the inner housing 22. The circulation fan 23 is disposed in the first blowing segment 241, a return air vent 224 is provided on the rear wall of the inner housing 22, an air flow inlet of the circulation fan 23 communicates with the return air vent 224, and two opposing air flow outlets 233 of the circulation fan 23 communicate with the second blowing segment 242 and the third blowing segment 243, respectively. As a result, the airflow that flows into the aging chamber 221 travels a relatively long path within the aging chamber 221 before flowing out from the return air vent 224, which prolongs the time the airflow is blown onto the surface of the aging object, thereby fully exerting the airflow drying effect on the object.

[0041] When the circulation fan 23 is operated, the airflow in the aging chamber 221 flows from the return air port 224 into the airflow inlet of the circulation fan 23, and then flows from the two opposing airflow outlets of the circulation fan 23 into the second airflow segment 242 and the third airflow segment 243, respectively. The airflows in the second airflow segment 242 and the third airflow segment 243 flow into the aging chamber 221 in the same direction through the airflow outlets provided in the two lateral side walls of the inner housing 22, respectively, thereby realizing airflow circulation between the blow air duct 24 and the aging chamber 221.

[0042] Moreover, the circulation fan 23 is disposed in the rear first air blowing segment 241. That is, when the ripening device 20 is disposed in the refrigerating / freezing apparatus 1, the circulation fan 23 is located on the rear side inside the refrigerating / freezing apparatus 1, so that the user is less likely to perceive noise caused by the operation of the circulation fan 23.

[0043] Specifically, the circulation fan 23 is a centrifugal fan with one-way intake and two-way outlet, which not only allows the airflow from the return air vent 224 to be simultaneously blown in two opposite directions to the two air ducts 24, but also reduces the space occupied by the circulation fan 23, making the structure of the ripening device 20 more compact and miniaturized, and preventing it from taking up too much space within the refrigerating / freezing device 1.

[0044] In some embodiments, both the second and third air blowing segments 242 and 243 are tapered along the airflow direction therein. Specifically, the airflow direction in both the second and third air blowing segments 242 and 243 is from rear to front, and the cross-sectional areas of the second and third air blowing segments 242 and 243 gradually decrease from rear to front, which avoids the phenomenon of the airflow speed in the second and third air blowing segments 242 and 243 gradually decreasing along the airflow direction due to the tapering of the flow area, ensures uniform airflow at all points along the length of the aging chamber 221, and ensures a uniform airflow effect on all areas of the longitudinal surface of the aging objects.

[0045] In this way, the material to be aged can be subjected to a uniform airflow blowing effect in both the horizontal and vertical directions (i.e., the front-to-back direction), improving the aging effect of the material to be aged.

[0046] The applicant recognizes that because the airflow initially enters the second air blowing segment 242 and the third air blowing segment 243 at a high speed, the intake volume of the air blowing ports communicating with the upstream sides of the second air blowing segment 242 and the third air blowing segment 243 may be small, resulting in a small blowing volume in the rear region of the aging chamber 221.

[0047] For this reason, in some embodiments, an air guide plate 26 is provided adjacent to the outer side of some of the air outlets upstream in the second air blowing segment 242 and the third air blowing segment 243. That is, the air guide plate 26 is provided in the air blowing duct 24 to block part of the air flowing through the air blowing duct 24 and guide that part of the air flow to the corresponding air outlet. As a result, a sufficient amount of air is ensured at the upstream air blowing port, further improving the uniformity of air blowing in the front-to-back direction within the aging chamber 221 and improving the aging effect.

[0048] Specifically, the air guide plate 26 extends from the outside of the air outlet into the air duct 24 in a direction perpendicular to the lateral side wall of the inner housing 221, and its extension length is less than one-third of the width of the air duct 24 at that position, ensuring that more air flows toward the downstream side of the air duct 24.

[0049] In some alternative embodiments, the air guide plate 26 may extend at an angle from the outside of the air outlet into the air duct 24, and the angle is set so that an acute angle is formed between the windward surface of the air guide plate 26 and the lateral side wall of the inner housing 221, thereby improving the airflow blocking ability of the air guide plate 26.

[0050] In some embodiments, return air inlet 224 is a circular air inlet, the center of the circle of return air inlet 224 overlaps with the center of circulation fan 23, and the diameter of return air inlet 224 is ¾ to 1 times the diameter of circulation fan 23. That is, return air inlet 224 may be slightly smaller than or equal to the diameter of circulation fan 23, but not exceed the diameter of circulation fan 23. This ensures smooth return air flow without affecting the air volume, and also prevents the phenomenon of part of the airflow being sucked back by return air inlet 224 without passing through the blower air duct due to return air inlet 224 being too large, thereby preventing the air volume from being affected.

[0051] In some embodiments, the height of the airflow outlet 233 of the circulation fan 23 is 2 / 3 to 5 / 3 of the diameter of the circulation fan 23. This avoids the problem that an airflow outlet that is too low increases airflow resistance and affects the air volume, while an airflow outlet that is too high not only fails to improve the air volume but also increases the structural dimensions and occupies a large space in the ripening device 20.

[0052] 4 is a structural schematic diagram of the internal structure of a circulation fan according to an embodiment of the present invention. In some embodiments, the circulation fan 23 includes a blower outlet casing 231 and an impeller 232 disposed within the blower outlet casing 231. The top of the blower outlet casing 231 has an arc-shaped structure with a central portion protruding upward. That is, an arc-shaped air guide structure is formed at the top of the blower outlet casing 231, which guides the airflow toward two airflow outlets 233 on either side in the lateral direction, thereby reducing airflow resistance and air loss.

[0053] Furthermore, the bottom of the circulation fan 23 is almost flat or has an arc-shaped structure with a downward recess in the center, and the degree of recession at the bottom of the circulation fan 23 is smaller than the degree of upward protrusion at the top, thereby minimizing the space occupied by the circulation fan 23.

[0054] The present invention also provides a refrigerated freezer. Figure 5 is a structural schematic diagram of a refrigerated freezer according to one embodiment of the present invention. The refrigerated freezer 1 of the present invention comprises a storage body 10, within which a storage compartment 11 for storing items is defined. In particular, the refrigerated freezer 1 further comprises a ripening device 20 described in any of the above embodiments. The ripening device 20 is used to ripen items therein, and is disposed in the storage compartment 11. The refrigerated freezer 1 integrated with the ripening device 20 has not only the conventional functions of preserving and maintaining freshness in a low-temperature environment, but also the function of ripening, thereby enhancing the functionality of the refrigerated freezer 1.

[0055] Furthermore, the storage device 11 may be a refrigerated compartment with a storage temperature range of 0 to 8°C, which is more suitable for the aging temperature requirements of the aging object. Furthermore, the storage humidity in the refrigerated compartment is usually higher than the humidity of the indoor environment, which is more suitable for the aging humidity requirements of the aging object. Even if the humidity in the aging device 20 is not appropriate, it can be easily adjusted by the airflow in the refrigerated compartment. Therefore, by installing the aging device 20 in the refrigerated compartment, the temperature and humidity conditions of the refrigerated compartment itself can be fully utilized, and costs can be minimized.

[0056] Furthermore, a freezer compartment and / or a temperature-variable compartment may be further defined in the cabinet 10. The refrigerator compartment, freezer compartment, and temperature-variable compartment are each pivotably mounted on a door on the front side of the cabinet 10, and may be selectively opened and closed.

[0057] It should be understood by those skilled in the art that the refrigerating and freezing device 1 of the present invention may be a cross-door refrigerator, and the ripening device 20 is provided in the refrigerator compartment at the top.

[0058] In some other embodiments, the refrigeration / freezing device 1 is not limited to the refrigerator structure shown in FIG. 5, but may be a double-door refrigerator, and the ripening device 20 may be installed in the upper refrigerator compartment.

[0059] In some other embodiments, the refrigeration / freezing device 1 is not limited to the refrigerator structure shown in FIG. 5, but may be a three-door refrigerator, and the aging device 20 may be installed in the upper refrigerator compartment.

[0060] In some other embodiments, the refrigeration and freezing device 1 is not limited to the refrigerator structure shown in FIG. 5, but may be a double-door refrigerator, and the aging device 20 may be installed in a storage compartment having a refrigerated storage environment.

[0061] In some other embodiments, the refrigeration / freezing device 1 is not limited to the refrigerator structure shown in FIG. 5, but may be a freezer, a horizontal freezer, or any other shape of refrigeration / freezing device, and the aging device 20 may be installed in a space having a refrigerated storage environment.

[0062] It should be understood by those skilled in the art that terms indicating orientation or positional relationship, such as "upper," "lower," "front," "rear," "top," and "bottom," used in the embodiments of the present invention are used based on the actual usage conditions of the aging apparatus 20 and the refrigeration / freezing apparatus 1. These terms are used only for the purpose of facilitating the description of the invention and understanding of the technical solutions of the present invention, and do not indicate or imply that such apparatus or device necessarily has a specific orientation or needs to be configured and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0063] Although several exemplary embodiments of the present application have been shown and described in detail herein, it should be recognized by those skilled in the art that many variations or modifications of the principles of the present application can be directly determined or inferred based on the disclosure of the present application without departing from the spirit and scope of the present application.
