Detailed Description
The present invention is to provide a refrigerating and freezing apparatus, and fig. 1 is a schematic configuration diagram of a refrigerating and freezing apparatus according to an embodiment of the present invention. The refrigerating and freezing apparatus 1 of the present invention includes a cabinet 10, and a refrigerating chamber 11 for storing articles is defined in the cabinet 10. Further, the cabinet 10 may also define a freezing chamber and/or a warming chamber. The refrigerating chamber 11, the freezing chamber, and the temperature-changing chamber are selectively opened or closed by door bodies pivotably provided at the front side of the cabinet 10, respectively.
In particular, the refrigerating and freezing apparatus 1 further includes a ripening apparatus 20, and the ripening apparatus 20 is provided in the case 10 for ripening the ripening object therein. Therefore, the low-temperature and high-humidity environment in the case 10 can be effectively utilized to promote the ripening of the ripening object in the ripening device 20, and a special cooling device and a special humidifying device are not required, thereby reducing the cost. The refrigeration and freezing device 1 integrated with the ripening device 20 not only has the storage and preservation functions under the traditional low-temperature environment, but also has the ripening function, and enriches the functions of the refrigeration and freezing device 1.
Fig. 2 and 3 are schematic sectional views of a ripening apparatus according to one embodiment of the present invention, taken along vertical sectional planes in different orientations, and fig. 4 is a schematic sectional view of a ripening apparatus according to one embodiment of the present invention, taken along horizontal sectional planes. Further, the ripening device 20 is selectively communicated with the refrigerating chamber 11, that is, the ripening device 20 may be communicated with the refrigerating chamber 11 under certain conditions or may not be communicated with the refrigerating chamber 11 under other conditions. The ripening apparatus 20 may include an inner circulation fan 25 and an outer circulation fan 27.
Fig. 5 is a schematic view of an air flow path of a ripening apparatus according to an embodiment of the present invention when an inner circulation fan is separately activated, and fig. 6 is a schematic view of an air flow path of a ripening apparatus according to an embodiment of the present invention when an outer circulation fan is separately activated. Referring to fig. 5 and 6, the internal circulation fan 25 is used to induce the air flow in the ripening apparatus 20 to circulate inside thereof, whereby the requirement of the surface wind speed of the ripening article can be secured by the internal circulation fan 25. The external circulation fan 27 is used for controllably inducing the air flow in the refrigerating chamber 11 into the interior of the ripening device 20 when the humidity of the air in the ripening device 20 exceeds a preset maximum humidity threshold. Thus, when the humidity in the ripening apparatus 20 is high (for example, immediately after the ripening article is put in), the air flow having relatively low humidity in the refrigerating chamber 11 can be introduced into the ripening apparatus 20 by the external circulation fan 27 to suitably reduce the humidity in the ripening apparatus 20 and prevent the ripening article from being deteriorated.
Specifically, the refrigerating chamber 11 has a storage environment for refrigerating and refreshing, the temperature in the refrigerating chamber is approximately between 0 and 8 ℃, and the humidity in the refrigerating chamber 11 is usually higher than that in an indoor environment, so that the refrigerating chamber is suitable for refreshing food materials. The ripening apparatus 20 is normally closed, and when the food is just placed in the ripening apparatus 20 at a pre-stage of ripening, the food itself contains a large amount of water and volatilizes much water, which causes the humidity inside the ripening apparatus 20 to be too high, which may exceed a maximum humidity threshold (e.g., 90%) required for the ripening of the food, thereby causing the food to deteriorate. At this time, the humidity in the refrigerating chamber 11 is relatively small, and the humidity in the refrigerating chamber 11 can be reduced by introducing the air flow in the ripening apparatus 20, and a special dehumidifying apparatus is not required, thereby simplifying the structure of the ripening apparatus 20.
It can be seen that, after the ripening device 20 is integrated on the refrigeration and freezing device 1, the original storage environment in the refrigeration and freezing device 1 is fully utilized to realize the ripening environment with proper temperature and humidity in the ripening device 20, the design idea is novel, the structure is ingenious, and the cost is greatly reduced.
In some embodiments, the ripening apparatus 20 is disposed in the refrigerating compartment 11 and includes an external air inlet 211 for allowing an air flow in the refrigerating compartment 11 to flow into the inside thereof and an external air outlet 212 for allowing an air flow in the ripening apparatus 20 to flow out. The outside air inlet 211 communicates with an air flow inlet of the outside circulation fan 27, and the outside air inlet 211 and/or the outside air outlet 212 are selectively opened or closed by a damper. That is, after the ripening device 20 is disposed in the refrigerating chamber 11, only the external air inlet 211 needs to be formed in the ripening device 20, and the air flow in the refrigerating chamber 11 can directly enter the ripening device 20 through the external air inlet 211 without providing an additional air duct under the action of the external circulation fan 27, thereby simplifying the structure. In addition, the opening and closing of the external air inlet 211 and the external air outlet 212 are adjustable and controllable through the air door, so that the problem that the taste of the inside of the ripening device 20 and the taste of the inside of the refrigerating chamber 11 are easily mixed because the external air inlet 211 and the external air outlet 212 are always opened is avoided, a relatively closed environment can be formed in the ripening device 20, and the ripening of the ripening objects is facilitated.
Specifically, the outside air inlet 211 communicates the airflow inlet of the outside circulation fan 27 and the refrigerating compartment 11. In one embodiment, the external outlet vent 212 may communicate the interior of the ripening apparatus 20 with the refrigerated compartment 11 to facilitate the flow of air from the ripening apparatus 20 back into the refrigerated compartment 11. At this time, an air duct is not required to be provided, the external circulation fan 27 drives the air flow to circulate between the inside of the ripening apparatus 20 and the refrigerating chamber 11, the flow path is short, the driving force is strong, and the flow rate of the air flow is fast, so that the humidity adjustment speed in the ripening apparatus 20 is fast. In another embodiment, the external air outlet 212 may also communicate between the interior of the ripening device 20 and other compartments within the enclosure 10, such as an evaporator compartment for housing an evaporator, to facilitate the flow of air from the ripening device 20 to the evaporator compartment. At this time, the external circulation fan 27 can drive the air flow to circulate between the inside of the ripening apparatus 20, the refrigerating compartment 11 and the evaporator compartment, and the humidity of the air flow in the evaporator compartment is lower than that of the air flow in the refrigerating compartment 11, so that the humidity in the ripening apparatus 20 can be adjusted relatively quickly.
In some embodiments, the maturation device 20 further includes an outer shell 21 and an inner shell 22 disposed within the outer shell 21, the outer and inner shells 21, 22 defining a blowing passage 24 therebetween. The inner casing 22 defines a ripening chamber 23 for containing a material to be ripened therein, and the ripening chamber 23 communicates with an air flow inlet of the internal circulation fan 25 through an internal return air port 224 provided in the inner casing 22 and communicates with the air supply passage 24 through an internal air supply port 222 provided in the inner casing 22. The internal circulation fan 25 is used to drive the air flow inside the outer casing 21 to circulate between the air supply passage 24 and the ripening chamber 23. The air outlet of the external circulation fan 27 is communicated with the air supply passage 24 to drive the air in the refrigerating chamber 11 to flow to the ripening chamber 23 through the external air inlet 211, the air supply passage 24 and the internal air supply outlet 222 in sequence, and the air in the ripening chamber 23 flows to the outside of the ripening apparatus 20 through the external air outlet 212.
That is, the ripening apparatus 20 has a two-layer structure of inner and outer shells, wherein a ripening chamber 23 is formed in the inner shell 22, and an air blowing passage 24 is formed in the outer shell 21 and outside the inner shell 22. The air flow driven by the internal circulating fan 25 or the external circulating fan 27 is sent to the ripening chamber 23 through the air supply channel 24, and the air supply channel 24 is shared by the internal circulating fan and the external circulating fan, so that the structure is simplified, and the air flow in the air supply channel 24 is relatively uniformly sent to the ripening chamber 23 through the design of the extending path of the air supply channel 24, so that the ripening effect of the ripening products is improved.
In some embodiments, both lateral sides of the inner case 22 are spaced apart from both lateral sides of the outer case 21, respectively, to form two air blowing passages 24. Both the air blowing passages 24 extend in the longitudinal direction of the inner case 22 and the outer case 21 (i.e., the direction perpendicular to the lateral direction), and the air blowing passages 24 are located laterally outside the inner case 22 and laterally inside the outer case 21. That is, the lateral side plate 221 of one side of the inner case 22 is spaced apart from the lateral side wall of the outer case 21 on the side, thereby forming one of the air blowing passages 24; the other lateral side plate 221 of the inner case 22 is spaced apart from the lateral side wall of the outer case 21 on the other side, thereby forming another blowing passage 24.
Further, the internal air blowing port 222 is opened on both lateral side plates 221 of the inner case 22. That is, each of the lateral side plates 221 is opened with an internal air blowing port 222. This allows the air flows in the two blowing ducts 24 to be sent to the ripening chamber 23 through the internal blowing ports 222 on the two lateral side plates 221. When the internal circulation fan 25 is started, the internal air flows into the ripening chamber 23 from both lateral sides of the ripening chamber 23 at the same time, improving the air supply uniformity of the air flow in the lateral direction of the ripening chamber 23, thereby improving the ripening effect of the ripening goods. When the external circulation fan 27 is activated, the air flows in the refrigerating chamber 11 simultaneously flow into the ripening chamber 23 from both lateral sides of the ripening chamber 23, improving the uniformity of the air flow supplied in the lateral direction of the ripening chamber 23, thereby rapidly and uniformly adjusting the humidity in the ripening chamber 23.
In some embodiments, the number of the air blowing openings 222 is plural, and the number and/or size of the plural air blowing openings 222 are set to make the air flow to all positions of the ripening chamber 23 uniform, further improving the ripening effect of the ripening article.
Specifically, the number of the air blowing ports 222 on each of the lateral side plates 221 of the inner case 22 is plural. The arrangement of the plurality of air blowing ports 222 on the two lateral side plates 221 may be symmetrically arranged.
Further, the sizes of the air blowing ports 222 are the same, and the arrangement density of the air blowing ports 222 on each lateral side plate 221 in the height direction of the inner casing 22 is uniform. The arrangement density of the plurality of air blowing ports 222 on the two lateral side plates 221 in the height direction of the inner case 22 is the same. Therefore, the air supply uniformity of each position in the height direction of the ripening chamber 23 can be improved, and the uniform air flow blowing effect on the upper surface and the lower surface of the ripening object is ensured; but also to make the humidity adjustment of the ripening chamber 23 relatively uniform in every area in the height direction.
Specifically, the plurality of air blowing ports 222 on the same transverse side plate 221 may be arranged in a plurality of rows and columns, and the hole pitch between any two adjacent air blowing ports 222 in the height direction is the same.
The applicant has realised that by using one internal circulation fan 25 or one external circulation fan 27 to drive the air flow in the two supply channels 24 towards the ripening chamber 23, the internal circulation fan 25 and the external circulation fan 27 must be upstream of the two supply channels 24. Therefore, the flow velocity of the air flow is gradually reduced in the air flow direction in the air blowing passage 24 (i.e., the longitudinal direction of the inner case 22). For this reason, when the sizes of the air supply ports 222 are the same, the arrangement density of the air supply ports 222 on each lateral side plate 221 in the airflow direction in the air supply passage 24 is increased stepwise or gradually.
Therefore, the defect that the flow velocity of the air flow in the air supply channel 24 is decreased gradually in the air flow direction can be made up in a mode that the arrangement density of the air supply openings 222 is increased gradually, the air supply uniformity of each position in the longitudinal direction of the ripening chamber 23 is improved, the uniform air flow blowing effect of each surface area of the ripening article in the longitudinal direction is ensured, and the humidity adjustment of each area in the longitudinal direction of the ripening chamber 23 is uniform.
Specifically, in one embodiment, the arrangement density of the plurality of air supply ports 222 on the lateral side plate 221 increases stepwise in the air flow direction in the air supply passage 24. That is, the lateral side plate 221 may be divided into a plurality of sections in the longitudinal direction, the arrangement density of the air blowing ports 222 in each section in the airflow flowing direction is the same, and the arrangement density of the air blowing ports 222 in the plurality of sections sequentially arranged along the airflow flowing direction is gradually increased. Specifically, the plurality of air blowing ports 222 on the same transverse side plate 221 may be arranged in a plurality of rows and columns, and the hole pitch between any two air blowing ports 222 adjacent to each other in the airflow flowing direction in the same section is the same. The hole spacing between two air supply outlets 222 adjacent in the longitudinal direction of the inner shell of a plurality of sections arranged in sequence along the airflow flowing direction is gradually increased.
In another embodiment, the arrangement density of the plurality of air blowing ports 222 on the lateral side plate 221 in the airflow direction in the air blowing passage 24 gradually increases. That is, the degree of increase in the arrangement density of the blowing ports 222 in the airflow direction is uniform. Specifically, the plurality of air blowing ports 222 on the same lateral side plate 221 may be arranged in a plurality of rows and columns, and the hole pitch between two adjacent air blowing ports 222 in the airflow flowing direction increases at equal intervals.
Therefore, the present application can obtain uniform airflow blowing effect and uniform humidity of the mature object in the transverse direction, the height direction and the longitudinal direction through the special design of the air supply channel 24 and the air supply opening 222, and the mature effect of the mature object is good.
In some embodiments, the inner housing 22 further includes an end plate 223 connected between the two lateral side plates 221 thereof, and the inner air return opening 224 opens on the end plate 223. The external air intake 211 is opened in a wall of the outer case 21 opposite to the end plate 223. The external outlet port 212 is located on the other side of the ripening apparatus 20 opposite to the side where the end plate 223 is located, and communicates with the refrigerating chamber 11. The inner circulation fan 25 and the outer circulation fan 27 are both disposed between the outer case 21 and the inner case 22.
Thus, both the internal airflow flowing into the ripening chamber 23 and the external airflow from the refrigerating chamber 11 can flow through a long path in the ripening chamber 23 and then flow out from the internal return air inlet 224 and the external air outlet 212, respectively. The internal air flow has longer blowing time on the surface of the to-be-cured product, and the air drying effect of the air flow on the to-be-cured product is fully exerted. The path of the external air flow passing through the ripening chamber 23 is long, and the humidity adjusting effect is good, so that each area in the ripening chamber 23 can be completely covered.
In some embodiments, the outer circulation fan 27 is on the outside of the inner circulation fan 25 facing away from the inner casing 22. The outer circulation fan 27 and the inner circulation fan 25 can be separated by a partition plate 28 to avoid the influence of the air supply paths of the two fans. The outer circulating fan 27 and the inner circulating fan 25 are both positioned at the rear side of the ripening device 20, i.e. the end plate 223 is a rear end plate, when the ripening device 20 is placed in the box 10, the inner circulating fan 25 and the outer circulating fan 27 are both positioned at the rear side of the box 10, and thus a user is not easy to feel noise generated when the fans operate.
Further, the inner circulation fan 25 and the outer circulation fan 27 are both single-direction air inlet and double-direction air outlet centrifugal fans. Therefore, not only can the air flow be blown to the two blowing channels 24 respectively towards two opposite directions, but also the space occupied by the internal circulation fan 25 and the external circulation fan 27 is reduced, so that the structure of the ripening device 20 is more compact and the volume is smaller, and the occupation of too much space in the box body 10 is avoided.
In some embodiments, the outer housing 21 is a cylinder with a front opening. The inner case 22 is a drawer with an open top, and the inner case 22 is disposed in the outer case 21 to be slidable.
That is, the outer case 21 of the ripening apparatus 20 is in the form of a cylinder, the inner case 22 is in the form of a drawer, and the inner case 22 is slidably provided in the outer case 21, so that the ripening chamber 23 in the inner case 22 can be easily put in or taken out of the ripening chamber 23, thereby improving the convenience of the user's operation.
In some embodiments, a rack 26 for holding the food to be cooked is disposed in the inner shell 22, the rack 26 has a plurality of hollow meshes, and the rack 26 is spaced apart from the bottom plate of the inner shell 22.
That is to say, the upper side and the lower side of the rack 26 have certain spaces, and the rack 26 is hollow, so that the airflow can blow the upper surface and the lower surface of the object to be cooked placed on the rack 26, thereby ensuring that the upper surface and the lower surface of the object to be cooked can be dried as soon as possible.
Moreover, the hollow rack 26 for placing articles also reduces the contact area between the object to be cooked and the rack 26 for placing articles, and prevents the partial surface of the object to be cooked from being deteriorated due to the fact that the partial surface of the object to be cooked is not contacted with air flow.
